Glass to Glass Bonding
Oren Alfi & Brandon Choi
Mentor: Dr. John LaRue

If one has ever attempted to bond glass to glass, they all would experience three things in common. The first is the presence of voids. The second problem is in finding glue that is both strong enough and thin enough to spread over the entire surface area. The third problem is finding the right solution to clean the glass with, so that there is no extra residue interfering with the glue that is used to bond the glass together. Some of the techniques used were cleaning the glass with liquinox, another detergent called Tween Twone, a brand called alconox, and a fourth by RCA-1 cleaning. All of these methods of cleaning will be discussed in its entirety in the report. During the rest of our research we will be looking into the use of epoxies to bond the glass. We will also be breaking the bonded glass in an MTS machine to test the strength of the bond.

Cultural Values Embedded in Mexican-American Children’s Literature
Emily Burch & Danielle Marie van Asch-Prevot
Mentor: Dr. Jaime Rodriguez

As Mexican immigration to the United States continues to rise, an increasing number of children are growing up with the challenge of negotiating two separate identities into one they can call their own. When children enter school they begin to learn to read. Often they are introduced to picture books first. Traditionally the amount and quality of children’s literature written for Mexican Americans has been limited. Early literature was written by other ethnic groups and often reiterated negative stereotypes. Since the 1960’s the emphasis on multiculturalism has risen. This project will consist of researching and analyzing children’s books between the ages K-3 in either Spanish or English and then compiling and streamlining the information. Books being considered are those with authors and topics focusing on cultural values of Mexican Americans.

Data Rate Wireless Transmission Using Cordless Phone Technology
Rex Chen & Robert On
Mentor: Dr. Nikil Dutt

Traditionally, the public switched telephone network (PSTN) was the primary device for communication. Today, however, the Internet has become the main form of communication by linking computer systems from hundreds of millions of users around the world. The continuous growth of the World Wide Web supports the projection that the future of communication devices requires the ability to send and receive valuable data transmissions. Increasingly, enabling the availability of data services for small embedded devices has gained popularity as the scope of the application that arises from this technology continues to grow. The computing industry has already shown significant interests in providing data transmission in addition to the typical voice calls and adapting data for the DSS cordless telephony is notable to many consumers. Data transmission in cordless telephony offers advantage over other technology sources such as cellular with its already ubiquitous deployment of PSTN infrastructure within home and office area spaces. It also provides low cost convenience of airtime-free services for the end users and many business areas can benefit from this technology. Our research focuses on studying the feasibility concern and concept proof of a cordless telephony technology to adapt wireless data transmissions. The project goal is to investigate feasibility issues of using an existing development system provided by Conexant Systems for alternative applications that requires data transmit. We studied the approach necessary to undertake this process and conducted code review to understand how communication for the cordless system works. Exploration of the assembly code review described some of our recommendations of the methodologies necessary to make the development platform more extensible for new feature enhancements.

EZ-P2P: A Next-Generation P2P Network with Enhanced Topology Management
Jeffrey Ma & Har Yau
Mentors: Dr. Tatsuya Suda & Dr. Junichi Suzuki

The file-sharing craze, ignited by the introductions of Napster and Gnutella, owes much of its success to inherently self-organizing and decentralized network protocols called P2P (peer-to-peer). While P2P has been deployed in wired static networks like the Internet, the next generation of P2P is being tailored for wireless dynamic (mobile) networks where nodes can move and power on/off sporadically. Next-generation P2P is ideal in such critical applications as emergency response and military operations to such everyday applications as retail distribution, floor planning, and pizza delivery services. However, current P2P protocols are not suited for mobile networks largely due to the lack of autonomous adaptability in topology management¾ the process of tracking connectivity among nodes. A node in traditional P2P probes neighbors within a communication scope or zone, defined by a radius, to stay connected. When the radius is big, excessive topology management traffic occurs because of the overhead to maintain a large zone. When the radius is small, longer delays occur between searches due to lesser network knowledge resulting from a smaller zone. An optimal zone radius is a hop count that simultaneously minimizes both of these issues. We have developed a next-generation topology management protocol, EZ-P2P (Evolving Zone-P2P), in which each node autonomously evolves its zone radius in response to the perpetual dynamism of a mobile network. We have already implemented EZ-P2P on our own simulator, conducted preliminary simulations to obtain its performance implications, and compared EZ-P2P with traditional P2P protocols.

Adult Bookstores and Secondary Crime
Christopher Hernandez & Kira Wong
Mentor: Dr. George Tita

This research involved the gathering of Calls For Service to the San Diego Police Department in an effort to recognize a pattern of criminal behavior around adult bookstores with peepshows within a certain time frame. While examining prior studies we utilized information from Professor Linz of UCSB. Actually, we replicated Linz’ research using different methods. After we gathered the addresses of the businesses, we constructed a database and combined it with the Calls For Service database that we had created. Three programs were utilized: SPSS, Excel, and Arc View 3.2 (GIS). SPSS was utilized to distinguish different types of Calls For Service that we obtained from the police records, they included: Arrest, Duplicates, Unfounded, Reports, and a call referred to as Other. We then transferred this information to Excel via Stat Transfer. This was done to concatenate the street names with the street numbers of the CFS. Excel was also used to concatenate the street names and the street numbers of the adult establishments. The data then was transferred to Arc View 3.2 (GIS) via Stat Transfer to project the information onto our map. Buffer zones were created 1000 ft from the establishments (experimental zone); we then began to tally up the CFS in these zones from the hours of 2 a.m.-6 a.m. We found that there was not an increase in CFS compared to an additional 1000 ft buffer zone (control zone), although we did find an increase in CFS around adult bookstores without peepshows. We recommend extensive research be conducted around these businesses.

Fecal Coliform Growth Potential in Dry-flow Urban Run-off Water from Laguna Niguel, CA
Aline Der Alexanian & Erica Dunbar
Mentor: Dr. Betty Olson

Clean Water Act Amendments called for fishable and swimable waterways and have recently established limits for urban runoff. Many cities are finding that run-off from residential streets exceed the discharge limit (2000 fecal coliform units per 100 ml) for secondary use streams. Fecal coliforms originate from animal sources. Our research will help to differentiate input from increases in fecal coliform numbers from growth because of this groups’ wide temperature range (15 ° C and 45 ° C) in waters with high levels of carbon. Our research addressed the question through the determination of the minimum doubling time for heterotrophic plate count (HPC) bacteria and E. coli in dry-flow urban run-off water. E. coli is one of the main fecal coliform indicators. Influent and effluent water samples were collected from two constructed wetlands. Water samples were divided to two portions: HPC counts were performed daily for 14 days and fecal Coliform growth was determined. Pasteurized water samples were inoculated with E. coli producing a final concentration of 50-cfu/100 ml and growth recorded daily for 14 days. Our results demonstrated runoff water supports fecal coliform growth with a minimum doubling time of 4 hr, indicating that discharge can exceed the limits through growth alone. Dissolved Total Organic Carbon analysis of each initial and final water samples indicated the amount of carbon converted into biomass confirming the bioassay for growth. Finally, HPC growth curves indicated the effect of predation on bacterial population numbers over each experiment, which will be related to fecal growth.

Antagonistic Pleiotropy Between Early Fecundity and Late Life in Drosophila melanogaster
Rupesh Kalthia & Francis Rocha
Mentor: Dr. Michael Rose

For many animal populations, mortality rates plateau late in life due to a decline in the force of natural selection. According to evolutionary theory, late-life fecundity rates should plateau in the same trend as mortality rates. The theory of antagonistic pleiotropy uses a genetic mechanism to explain mortality rate patterns in different populations. It should also theoretically explain varied fecundity rate patterns. To test this, we reverse selected replicates of Drosophila melanogaster for an earlier last age of reproduction for several generations. We then made a pair-wise fecundity comparison with those populations and their progenitor lines and used a two-stage linear model to determine the effects that the change in last age in reproduction have on the onset of late-life fecundity plateaus. In the experiment, the data did not clearly show a fecundity plateau or an effect of antagonistic pleiotropy on the change of fecundity rates. Neither the new replicates nor their parental lines fit to a two-stage linear model for fecundity rates. The lack of adherence might be due to experimental design, as the methods had two different variables from previous experiments on late-life fecundity in Drosophila melanogaster. It could also mean that unlike the force of natural selection, the genetic mechanism of antagonistic pleiotropy primarily has an effect on mortality rates and not fecundity rates. The results of the experiment are too inconclusive to support any conclusion on the relationship between the theory of antagonistic pleiotropy and late-life fecundity plateaus.

No Man’s Land: A Look at the Environmental Discrimination of U.S. National Parks
Elita Johnson and Antoinette A. Brown
Mentor: Dr. Richard Matthew

As minorities experience the greatest social mobility in the 21st century, one segment of society that remains untouched by this change is our national park service. By 2050 people of color will make up nearly 50% of the population of the United States, yet there is a visible gap between communities of color and visitation to the national parks. The challenge of national parks in the 21st century is to build a multicultural foundation in a seemingly public space such as nature, make national parks a true treasure of American culture, and make it a place of comfort and accessibility to all groups. The premise of our research is to examine why minorities, particularly African Americans, are largely absent to national parks, specifically Yosemite National Park. We will focus on the external factors that support this trend, such as perceptions of how different cultures recreate exposure to nature, accessibility, advertising, as well as a host of other significant variables. In examining these factors we will also look at how the park system, as a bureaucratic body, sustains and supports the racial segmentation of Yosemite National Park. From our findings, we will show how the barriers between national parks and people of color were created and how it continues to thrive centuries after the park service was created. We have found that early exposure (childhood/youth) to wilderness and nature is the key to bridging minorities toward visitation to national parks. With an early exposure to the park, minorities will feel comfortable outside an urban setting, enjoy the resources and experiences that the park service provides, and with greatest hope, recreate according to what interests them rather than what culture and society dictates.

A Review of the "O" Populations of Drosophila melanogaster
Cheryl-Ann Dacayo & Janice Doan
Mentor: Dr. Michael Rose

The "O" populations were derived in February 1980 from a single population of Massachusetts Drosophila melanogaster designated IVES (IV) from P.T. Ives’ lab. The purpose of the O selection was to increase late life net fertility by making natural selection favor females that are able to produce eggs late in life. The O stock has a ten-week generation time with two weeks in the standard larval stage in vials and an extended eight weeks of adult phase in their selection cages. The maintenance of the O population starts with flies dumped into their cages after two weeks in incubation. An eight-week routine procedure follows with feeding banana food plates to the flies, yeasting to increase fecundity, egg collection, and the transfer of the backup population to their new food vials. After maintaining the O stock for over seven generations, the population demonstrated an increased susceptibility to contamination. Contamination caused us to collect eggs early, which shortened the generation time to less than the normal ten week cycle. In our lab, the O-stock was utilized in experiments that measure the fecundity of female fruit flies under different environmental conditions. These "O" flies have been one of the most important stocks in the world for the postponement of aging. They have life spans 2-3 times greater than those of their ancestors, along with many other physiological enhancements.

Stereoselective Synthesis of (E)-Alkenes by Copper-Mediated Allylic Substitution Reactions of (Z)-Allylic Carbamates by Organometallic Nucleophiles
Jennifer Moore & Anh Pham
Mentor: Dr. Keith Woerpel

Copper-mediated allylic substitution reactions represent important methods for construction of alkenes. (E)-alkenes were obtained with high selectivity when (Z)-allylic carbamates were treated with hard organometallic nucleophiles, such as alkyllithium or alkylmagnesium halides. Because the use of these hard nucleophiles limits the functional group compatibility, softer nucleophiles were investigated. The reaction of (E)-allylic carbamates with soft organometallic nucleophiles gave only modest (E)-selectivity. The reaction of (Z)-allylic carbamates with soft organometallic nucleophiles, such as organoaluminum and organozinc reagents, however, afforded (E)-alkenes with high selectivity. We have also shown this reaction could be utilized to synthesize (Z)-allylic silanes with high selectivity.

Scooter Collision and Accident Trauma and Epidemiology Report (SCATER)
Venice Cercado & Elena Marveya Tarango
Mentor: Dr. Julie Gorchynski

There has been a dramatic increase in the use of unpowered (foot propelled) scooters since its "reinvention" in 2000 from its prototype in the 1950’s. Although the CDC reports that scooter use incurs minimal injuries, the advent of more advanced scooters, such as powered versions, show injury estimates that drastically increased from initial estimates. In addition, guidelines and safety recommendations reported by the CDC and the CPSC were projected from skateboard and in-line skate and injury data and not directly from scooter related accidents. Since only a few studies have been done on this subject, this current study was designed to investigate scooter-related injuries in relation to different variables. As part of the current investigation, data have been collected from 30 subjects for over a period of nine months. All patients reporting to the Emergency Room at UCI Medical Center with injuries related to scooters were included in a study on scooter injury and safety. The study involved 25 questions regarding the events surrounding the scooter injury that the patient provided, as well as the diagnosis, treatment and results documented by the M.D. Data analysis is currently in process. Planned analyses will show indicative patterns between scooter-related injuries and factors attributed to the injury including environmental factors, equipment variability, user demographics and scooter safety knowledge. The findings of the study will help us understand significant correlations between particular variables and scooter-related injuries, allowing for updated preventative health measures and recommendations on scooter use.

Effect of Free Bicycle Helmet Distribution to Children of Low-Income Families from an Emergency Department
Tina (Baotin) Chuong & Tejdeep Kochhar
Mentor: Dr. Kenneth Kwon

Despite the popularity of bicycling in the United States, bicycling is also a significant source of morbidity and mortality. Each year, there are more than 580,000 emergency department (ED) visits and about 1000 deaths. The most serious bicycle injuries are head injuries, which account for up to 100,000 yearly ED visits and up to 90% of all bicycle crash fatalities. Many studies have shown that bicycle helmets significantly reduce morbidity and mortality in all ages. However, despite its effectiveness, helmet use was estimated to be less than 18% in 1992, with the lowest rates in children between 11-14 years. There have been many studies investigating the effects of free helmet distribution, with mixed results. Some studies have shown an increase in usage, while others have shown an increase in ownership but not in regular use. Due to a recent mini-grant, UCI Medical Center ED will distribute approximately 250 free helmets along with safety information to low-income families. The main objective of this study is to quantify the degree of helmet use in children of low-income families who are given free helmets and bicycle safety information in the UCI Medical Center ED. Each subject and their parent(s) were surveyed on their bike safety and helmet usage. Two-week and six-month follow-ups were done to determine bicycle helmet usage. Data analysis is still being conducted. An increase in bicycle helmet use is expected for children who are given free helmets and also for children who already owned a helmet and were only given bicycle safety information.

Effects of Microgravity on Intracellular Signaling Proteins Mechanism of Vascular Smooth Muscle Contraction
Sang Le & Trang (Jan) Nguyen
Mentor: Dr. Ralph Purdy

Under normal upright posture, the blood pressure gradient in humans is distributed 70 mmHg at the head and 200 mmHg at the feet. However, exposure to microgravity in space alters the gradient to a uniform 100 mmHg throughout the body. Upon returning to Earth, many astronauts encounter cardiovascular problems such as tachycardia, hypolvemia and orthostatic intolerance. In a study conducted by Buckey et al., fourteen out of nineteen astronauts returning from space failed a ten-minute stand test. It was determined that those who did not pass showed an inability to raise their total peripheral resistance upon returning to Earth’s gravitational condition. One possible explanation for this occurrence may be the effects of microgravity on second messenger signal transduction in arterial smooth muscle cells. Our current study focuses on the effects of microgravity on the expression levels of c-Src and p38 MAPK, two crucial second messengers in the smooth muscle contraction pathway. To simulate microgravity rats underwent hindlimb unweighting (HU). After 20 days of HU treatment, carotid, abdominal, thoracic, and femoral arteries were removed from control and HU rats. Western blot analysis was conducted to determine the levels of c-Src and p38 MAPK in the blood vessels. Thus far, results indicate that p38 MAPK expression level drastically decreased by HU treatment in carotid and femoral arteries and also in abdominal and thoracic aorta arteries. Additional analysis is taking place and aims to further investigate the effects of microgravity on the function of signal transduction second messengers, p38 MAPK as well as c-Src.

Laparoscopic Cooled Tip Microwave Thermotherapy for Destruction of Experimental VX-2 Renal Tumors in Rabbits: Comparison to Cryotherapy and Radical Nephrectomy
Corollos Abdelshehid & Ian Casimiro
Mentors: Dr. Ralph Clayman & Dr. Louis Eichel

We elected to compare the ability of a prototype 3.5 mm cooled tip microwave probe to destroy experimental renal tumors with cryotherapy and radical nephrectomy. The VX-2 tumor line in rabbits is highly malignant with great metastatic potential. Thirty-five rabbits were divided into 7 groups of 5: 1) microwave VX-2 therapy with a 3.5 mm cooled tip probe; 2) cryotherapy of VX-2 with a 2.3 mm probe; 3) laparoscopic radical nephrectomy for VX-2; 4) no treatment of VX-2; 5) microwave of normal renal tissue (NRT); 6) cryotherapy of NRT; and 7) no treatment of dead VX-2 tissue. All VX-2 rabbits had a 1 mm3 VX-2 tumor implanted under the renal capsule. Control rabbits had laparoscopic kidney mobilization. Five days post tumor implantation, treatment was given. One month later, all animals were autopsied; kidneys were sectioned and stained for H and E. At 5 days, tumors achieved an average size of 3 mm x 4 mm. During microwave treatment, interstitial fluid emanated from the probe path. At 1 month, in the microwave VX-2 group, 5/5 had local recurrences, 3/5 had extensive metastatic tumor encasing the abdominal compartment and 2/5 had lung metastases. At 1 month, in the cryotherapy VX-2 rabbits, 1/5 had a local recurrence and 2/5 had small volume metastases to lung or stomach. At 1 month, in the radical nephrectomy group, there was no local recurrence or metastases. In the VX-2 implanted control rabbits, 5/5 had extensive local kidney tumors and lung metastases; 2/5 had peritoneal metastases. In conclusion, neither cryotherapy nor microwave therapy was as effective as radical nephrectomy. Violation of the VX-2 tumor with a probe may cause intraperitoneal seeding; this was more prevalent with the cooled tip microwave probe.

Effects of Simulated Microgravity on Voltage Operated Calcium Channels
Julie Huynh & Alina Saechong
Mentor: Dr. Ralph Purdy

Microgravity causes cardiovascular deconditioning effects, including orthostatic intolerance. One important underlying cause of orthostatic intolerance is thought to be the inability to raise total peripheral resistance leading to a person’s limited ability to stand upright. Voltage operated calcium channels (VOCC) are known to be an essential component in mediating vascular smooth muscle contraction by making calcium available for calmodulin binding, subsequent activation of myosin light chain kinase, and phosphorylation of myosin light chain 20. The objective of this study was to investigate microgravity effects in VOCC expression in abdominal and thoracic aortas. Male Wistar rats were hindlimb unweighted (HU) for 20 days in order to simulate microgravity. The abdominal aorta and thoracic aorta were isolated and cleaned of extraneous tissue. Western Blot analysis revealed a 20% decrease in VOCC protein in HU abdominal aorta. Similarly, the HU-treated thoracic aortas revealed a 40% decrease in VOCC expression. The HU-induced down-regulation of VOCC expression strongly suggests that reduced cytosolic calcium in HU treated tissues may be an essential factor in the marked vascular hyporesponsiveness. Further studies are necessary to determine additional alterations to calcium channel signaling proteins in vascular smooth muscle contractions.

Data Mapping and MIDI Scheduling for the Vicon-8 Motion Capture System
Mark Magpayo & Maybelle Tan
Mentors: Dr. Fred Bevilacqua, Dr. Christopher Dobrian, & Dr. André van der Hoek

Motion capture systems such as the Vicon-8 create a 3D representation of a live performance. It uses eight cameras positioned strategically to plot movements in 3-dimensional space. Traditionally, these systems have been used for biomechanics studies and in the entertainment industry for animation, computer games, and visual effects. However, these applications in essence map the movements captured by the system into animations or visualization interfaces. The focus of the project is on using these movements to instead create new channels of expression through music. Based upon the motions of a performer, the system will be used to generate data adhering to the Musical Instrument Digital Interface (MIDI) protocol. Parts of the body are mapped to different controls on a MIDI synthesizer, such as pitch, volume, and velocity. These controls would allow a performer to create original musical pieces based entirely on physical movements.

Lipid-Lowering, Antithrombotic, and Anti-inflammatory Effects of Ayurvedic Therapies
Tony Khan & Alan Rillorta
Mentor: Dr. Nathan Wong

Maharishi Ayur-Ved is a comprehensive healthcare system that dates back more than 5000 years to the ancient Vedic civilization of India. It is prevention-oriented and focuses on treatment of chronic ailments. Certain herbal products have been reported to have possible cardiovascular benefits, including effects on lowering cholesterol, blood pressure, and improvements in other cardiovascular risk factors. This study will evaluate the efficacy of Maharishi Ayurvedic Cholesterol Protection herbal therapy on lipids and other cardiovascular risk factors. Specifically, the following will be investigated: the efficacy of Ayur-Vedic CP therapy on lowering total and low-density lipoprotein-(LDL)-cholesterol in persons with moderate elevations of LDL-cholesterol and the efficacy of Ayur-Vedic CP therapy on reducing systemic inflammation and thrombotic potential. Subjects will be randomized to either the active Ayurvedic product or equivalent placebo. The randomization visit will involve conducting a fasting lipid profile, vitals, Lp(a), c-reactive protein, and fibrinogen measures. Follow-up visits are conducted after 4, 12 and 24 weeks on treatment or placebo. At each follow-up visit a lipid profile is done. At the last treatment visit, all measures obtained at randomization, as well as chemistry profile are obtained. Study data will be coded into SAS data format for analysis. Initial analysis will involve comparison of all measures at baseline between treatment groups. Repeated measures analysis of variance will examine for group differences in changes in values for lipids across treatment visits from baseline, and the student’s t-test will examine for differences in the change in each of the other parameters from baseline to follow-up between treatment groups. Multiple logistic regression will examine the likelihood of achieving NCEP lipid goals in the Ayurvedic group versus placebo, after adjusting for baseline medical history and lipid parameters.

The Effects of S-Adenosylmethionine (SAMe) on Osteoarthritis of the Knee
Purvi Patel & Michelle Rubinstein
Mentor: Dr. Jerome Tobis

The intent of this study was to conduct follow-up interviews with 56 participants who had completed a double-blind cross-over study on the effects of S-Adenosylmethionine (SAMe) vs. Celebrex for osteoarthritis (OA) of the knee. After the original study was completed and the participants knew which medicines they took, we interviewed participants to determine which of the two drugs was preferred and why. Forty-seven out of 56 patients were contacted via telephone, email, and postal address to ascertain pain levels, methods of pain management (SAMe, Celebrex, other NSAIDs, exercise, etc.), and if the cost of medicine affected the choice of pain control. Even though the results indicated both medicines were effective in reducing knee pain, 14 out of 47 participants preferred SAMe over Celebrex. Participants recalled having minimal side effects with SAMe, compared to Celebrex, while study data had actually revealed no significant differences in side effects. During the follow-up interviews (about 6 months after study completion), SAMe appeared to participants to be more tolerable and effective with easing arthritis pain. Out of the 14 patients who favored SAMe over Celebrex, 3 actually followed up with the treatment of SAMe for their knee pain. Cost was an issue for the remaining participants because SAMe is not covered by health insurance. Thus, patients tend to turn to medications that are covered by insurance, even though they would prefer a supplement, which they perceive to have fewer side effects.

MicroMouse Project

Mentor: Dr. Roland Schinzinger

The simple concept of a mouse navigating a maze was made complicated when the mouse must be a fully autonomous robot. This is the challenge that was approached in the MicroMouse Project. With no previous background, we designed a mouse that consisted of the latest motor, battery, power distribution, and microprocessor technologies to bring ultra low power usages, high intelligence, and mobility. Breaking up into three teams, hardware, software, and mechanical, we broke down the different aspects of the mouse. Forty-eight ultra-small infrared sensors were placed on eight arms to monitor the distance from walls while forty-eight corresponding LED indicator lights allowed for error detection and efficient debugging. Two bipolar stepper motors and gearboxes provided precision movement and maximum torque. The "brains" of the mouse consisted of a microprocessor called Microblaze given to us by Xilinx Inc. This soft processor was programmed into a semiconductor device called an FPGA (Field Programmable Gate Array). The FPGA contained the maze solving algorithm, sensor interpretation, and motor movement functions that allowed the mouse to navigate and intelligently make decisions to solve the maze.

A Distributed Architecture for the Rapid Development and Deployment of Wireless Markup Language (WML) Based Applications
Hooman Afghani, Chin-Ju Chen, & Gary De La Cruz
Mentor: Dr. Tatsuya Suda

WML (Wireless Markup Language) is used to create web pages that can be displayed in a WAP (Wireless Access Protocol) enabled browser on wireless devices such as cell phones and PDAs. The proposed architecture is a modification of the OSI network layer model separating the software system into 3 distinctive layers: (1) data layer, (2) logic layer, and (3) presentation layer. In this architecture, the three layers are implemented in mySQL, Java Servlets, and ASP.NET mobile-forms respectively. The development methodology is based on the concept of a distributed system establishing a simple message passing protocol to allow heterogeneous components to communicate with one another regardless of the language implemented or physical locality. Applications are written in an object-oriented fashion using java Servlets that can retrieve data from a database and output processed information with the presentation parameters to an ASP.NET page that generates the actual WML code to be displayed on the wireless device. WML, similar to HTML, is a relatively simple language and the use of ASP.NET mobile forms to generate WML gives us rich facilities for session tracking, state management, WML code abstraction, and guaranteed correctness of the WML code generated. With the WML-based application, the fundamental software engineering principles such as reusability, robustness, testability, modularity, and abstraction are preserved. Also, the distributed nature of this architecture adapts characteristics including scalability, portability, resource sharing, heterogeneity, redundancy, and transparency. In our experiment, we demonstrated the benefits of using the architecture and environment versus its absence and contrasted the two case studies based on a sample application we developed.

Seasonal Variations in Mood: Impact on the Smoking Behavior of Young Adults
Forough Ghavami Shirehjini, Roxanna Ramirez, & Melody Yi
Mentor: Dr. Larry D. Jamner

For a number of people, the winter holiday season is associated with the experience of greater stress and negative moods (Rohan & Sigmon, 2000). Among the possible health consequences of elevations in negative mood states is the risk of increased cigarette consumption. Unaware of published studies that have examined the effects of seasonal shifts in mood on smoking behavior, we hypothesized that the winter holiday period would precipitate greater smoking behavior through the elicitation of depressive symptoms. With data collected from a pool of approximately 220 college students, whose moods and smoking behavior were experience-sampled every 30 minutes over several four-day ambulatory monitoring periods, we initially compared the data collected between December 1 and January 31 to data collected between April 15 and June 15. Preliminary analysis revealed generally greater levels of diary-reported negative emotions and urges to smoke during the holiday compared to the spring period. However, this effect appeared to be moderated by smoking history: larger shifts in moods and urges to smoke across the two seasonal periods were more apparent for heavier, perhaps more tobacco-dependent, smokers whereas smaller shifts were more apparent for non-smokers and smokers with low levels of cigarette consumption. The pattern of findings is consistent with the notions that vulnerable individuals may smoke in an attempt to alleviate negative moods and depressive symptoms and that certain subgroups of individuals may be more vulnerable to experiencing seasonal "blues." Further analyses are underway to shed light on additional factors predictive of seasonal influences on mood-smoking linkages.

Boston Suicides
Austin Chu, David Shiroma, & Angeline Wu
Mentor: Dr. George Tita

On December 30, 1996, there was an outbreak of suicidal behavior among adolescents in the community of South Boston, a mostly white, low-income, urban Irish Catholic neighborhood of Boston, Massachusetts. In twelve months, there were seven completed suicides, 19 medical hospitalizations for self-injury, and almost 400 other mental health crisis screenings, including many other less medically serious self-injuries, recorded by several emergency teams serving the community. This project seeks to answer the following questions: 1) did adolescents living nearer to the youth programs in this community have a lower likelihood of self-injury during this outbreak? 2) If so, are the correlations better explained by some other factor? 3) Are there differences in the time and space distribution of more and less serious self-injury events? 4) Are there differences in the time and space distribution of self-injury events, according to the method of self-injury? Our aim was to visually represent the data that was collected. Using a program called ArcView GIS (Global Information System), we will interpret the data and display various trends and characteristics of these events. Moreover, this project will allow people to comprehend the raw data, physically see the occurrences on a map and eventually understand the problem as a whole. After mapping out the neighborhood and pinpointing the location of completed and attempted suicides using GIS, we were unable to find a connection to the surrounding community centers in South Boston. In our conclusion we describe the drawbacks and explanations to our findings.

The Relationship Between Carotid Luminal Pathology and Preoperative Symptoms
Jessica Chang, Prashant James, & Jacqueline Seifert
Mentor: Dr. Peter Lawrence

Atherosclerosis of the carotid artery is the most common treatable cause of stroke. The percent stenosis (narrowing) of the carotid artery is the primary indicator of the need for carotid endartarectomy (plaque removal). However, the pathology of carotid artery plaques has also been used to predict stroke risk but the relationship is less clearly defined. Some studies have suggested that carotid plaque morphology, such as composition of the plaque contents and the luminal (adjacent to blood flow) surface of the artery in the area of the plaque, are independent risk factors for stroke, and provide additional information to percent stenosis. Luminal irregularities, which occur on the blood flow surface, may be the most significant pathologic predictor to risk of stroke but have been difficult to evaluate since they are altered in the process of plaque removal. Recently, a technique of "no touch" plaque removal, in which the pathology remains undisturbed, has allowed a better evaluation of luminal pathology. This study was conducted to determine whether there was a correlation between luminal surface characteristics and preoperative symptoms, which are an indication for carotid endarterectomy. Luminal findings can then be correlated with stroke risk and diagnostic studies, which evaluate luminal characteristics, and can then be used to predict which plaques have the greatest risk of stroke and which patients have the greatest need for surgery.

Satisfying the Judicial Gatekeeper: Assessing Legal Standards for the Reliability of Expert Testimony
Khoa Le, Star Lopez, & Pouya Ziapour
Mentor: Dr. Caesar Sereseres

Who are "expert witnesses"? What effects do they have upon juries and judges? When should they be allowed to testify? Why are there two different methods of determining the validity of an expert (California and Federal)? Where are the potential abuses in the system? How can science and law have a mutually beneficial relationship in the courtroom? All these questions and more present themselves upon even a cursory study of the world of the expert witnesses. The topic of expert witnesses and their testimonies has become more and more a part of the drama in a courtroom. The plaintiff and defendant both marshal witnesses to their side to explain, in favorable terms, highly technical and specialized knowledge. Many people, however, can claim to be and know many things, regardless of their actual validity. In order to facilitate the separation of the wheat from the chaff, two different methods of testing validity have arisen in state and federal courts. While expert witnesses must qualify under the Kelly-Frye general acceptance test in California State courts, federal courts utilize the Daubert test, which involves more liberal qualifications. This research group evaluates the usefulness of expert witnesses in court, how the varying qualifications of expert witnesses in state and federal courts have led to forum shopping in court cases, and how the highly technical nature evident in much expert testimony may cause judges to be unprepared to make the decision between what qualifies as "good science" and what qualifies as "junk science."

"Five Minutes More"—Dance Performance
Crystal Hernandez, Marc Macaranas, & Sunny Staton
Mentor: Dr. David Allan

During the summer of 2002, with the aid of UROP, I was able to further explore my area of research: choreography. With support from the Sacramento Ballet, I spent time in their studio creating a new work for dancers from the ballet company and two dance majors from UCI. The piece was entitled "Love Swings" and contained two sections. The first section highlighted three different duets displaying different aspects of love, while the second section was a celebration of love set on twelve dancers in a highly explosive number. The choreography was highly effective as a strong piece of entertainment, one of the goals I intended to pursue with this project. The second goal I set for myself was to explore the different relationships between men and women and be able to effectively display this through dance. I was happy to receive positive feedback from my mentor, David Allan, as well as the Sacramento Ballet’s Artistic Directors and the audience at large.

Managing the Evolution of Software Architectures
Ping Chen, Matthew Critchlow, Akash Garg, & Christopher Van der Westhuizen
Mentor: Dr. André van der Hoek

Currently, many modern software organizations develop closely related software products as single, unrelated efforts. As a result, many high-level design decisions are lost between products and reuse remains ineffective or limited to the code level. One solution is to create a generic design architecture, which is able to capture an entire family of closely related products, called a product line architecture (PLA). The PLA explicitly describes the common features shared by all the products as well as the points of variation among the individual products. Variation points are either optional (it is not required) or variant (it may take different forms in different products). PLAs change over time as new products are added, old products are retired, and existing products are changed. Currently, there are no tools to manage the resulting evolution of a PLA. Furthermore, manually evolving a PLA is a painstaking and error-prone process. To address this problem, we have developed four tools for the management of PLAs. The first tool, Ménage, is a design environment for specifying product line architectures and their evolution. The second tool, ArchSelector, automatically selects a single product by resolving each variation point based on some user-specified product features. The third tool, ArchDiff, helps in understanding the difference between two products by calculating an architectural "diff". Finally, ArchMerge propagates such a diff to another product in the PLA. This supports the propagation of features from one product into another product, and can be done either statically (at design-time) or dynamically (at run-time).

Inter-domain Routing Exchange Model Simulator
Ryan Creasey, Jianan Guo, Patrick Lo, & Robert On
Mentor: Dr. Tatsuya Suda

With the ever-increasing volume of traffic on the Internet and the demands for Quality of Service, traffic has been classified into different service classes with different priorities. The premium class traffic has the higher priority and customers requiring such priority would be willing to pay for that premium. Deploying premium flows such as video, audio and VPN traffic through several domains requires that every domain along the selected path agrees to offer these special services to ensure high priority data is transmitted efficiently. Present inter-domain premium traffic management frameworks are typically detailed and complex, requiring time-consuming human negotiation between domains to establish service level agreements that are often inflexible to the demands and dynamic nature of network flow. iRex stipulates that better Quality of Service can be achieved if this service level agreement framework could be automated and dynamic, allowing all price and purchase decisions up to the domain routers. The Inter-domain Routing Exchange model simulator will provide a means to discern the overall feasibility of full implementation of the iRex model as well as provide invaluable insight into the results of implementation. Such events that may only occur in the implementation of iRex would be exhibited in the simulation and allow for study. The simulator would require similar configuration files as the expected implementation of the project, thus making a transition to the fully implemented project easier. The results of this simulator will prove invaluable toward the quest proving iRex as a viable QoS management and routing technology.

Minority and Immigrant Perceptions of Policing and the Legal System: Analysis of a Latino Community
Adriana De La Torre, Louisa Ko, Blanca Serrano, & Yanira Torrez
Mentor: Dr. John Dombrink

This presentation focuses on findings from a community survey of minority, largely immigrant Latino residents, and informant interviews with Latino community leaders in a Southern California community. The purpose of this study was to provide preliminary data on the attitudes of Latino residents in Westside Costa Mesa regarding their perceptions and experiences with the police, legal system, and community. One hundred and fifty telephone interviews with residents of Costa Mesa and several interviews with community leaders were collected to gain information on community concerns and their opinions of local law enforcement. Key analyses involve the experience of residents with the legal system and with police, attitudes toward the police, and willingness to participate with the criminal justice system. Findings from this study will be implemented into community interventions for the improvement of community and police relations.

The Progression of Alzheimer’s Disease in Down Syndrome
Navid Alem, Saba Hamiduzzaman, Ramin Rahimian, & Tramanh Vu
Mentor: Dr. Linda Nelson

Alzheimer’s disease (AD) is a debilitating disease exemplified by severe problems in reasoning and recall. Often, the cognitive decline is so accelerated that death ensues within 10 years of AD onset. Although AD may afflict a large percentage of the general population, the Down Syndrome (DS) population is most susceptible to acquiring AD. Their high susceptibility is largely due to triplicate coding on chromosome 21 for the ß-amyloid precursor protein. This polysomy ultimately results in over-expression of the ß-amyloid protein that causes senile plaque formation associated with AD dementia. Hence, an opportunity to characterize the progression of AD presents itself by analyzing the DS population. Through cognitive testing, the goal of our study is to help identify neuronal pathways that are showing signs of dementia. In so doing, interventions designed to slow the progression of AD may be improved. Due to similar brain/behavior associations, we are using an animal model previously performed on canines and nonhuman primates to test our DS subjects (Head et al., 1998). Each animal based task represents a specific brain region or neuronal pathway. We are currently retesting subjects to document any cognitive deterioration over time (i.e., dementia). Preliminary results (n = 7) show that specific animal-based tasks are potentially useful in identifying early signs of AD in a high-risk population. We hope that our findings will one day play a role in alleviating the suffering associated with the devastating effects of AD.

A Validation Study of the Beck Depression Inventory, Center for Epidemiological Studies-Depression Scale, and the Self-report Depression Scale for Korean Americans
Sarah Lee, Jennifer Nguyen, Yong Park, & April Yabiku
Mentor: Dr. Jeanett Castellanos

Studies utilizing self-report depression scales (i.e., Center for Epidemiological Studies-Depression (CES-D) and the Self-report depression scale (SDS)) show that Korean Americans consistently exhibit higher depression rates compared to other Asian Americans as well as Caucasian Americans. The validity of the findings needs to be examined since neither the CES-D nor the SDS was validated and normed for use with Asian Americans. Asian Americans, including Korean Americans, may exhibit depression symptoms differently than other race/ethnicity groups due to cultural differences. Approximately 150 Korean Americans will be assessed in the current study to evaluate the reliability and validity of the Beck Depression Inventory (BDI), CES-D, and the SDS. The split-half method will assess the internal consistency of the scales. Correlation of the three scales’ scores will be used to assess convergent validity. The symptom expression variable, measured by the Memorial Symptom Assessment Scale (MSAS), will be included to measure the criterion validity. Clinical and research data shows that Korean Americans may express psychological symptoms in somatic form. Therefore, less acculturated, measured by the Asian Values Scale (AVS), Korean Americans who are depressed should exhibit more somatic symptoms than acculturated Korean Americans. Implications of results and suggestions for future research will be provided.

Girls’ Night Out: A Tribute to Women in Musical Theatre
Jennifer Alvarez, Stephanie Linn, Saskia Saffir, & Bonnie Wickeraad
Mentor: Dr. Mary Leslie Ishii

The most memorable artists in the entertainment industry are those who, in addition to having talent and skill, have embraced their individuality. Developing a cabaret show celebrating women in musical theatre required research and planning for its success. To create a script connecting the lives of four women in musical theatre, Judy Garland, Ethel Merman, Bernadette Peters, and Barbra Streisand, involved collaboration and insight from everyone engaged in the project. Time was devoted to watching various theatrical performances, concerts, reading interviews, biographies, fans’ opinions, critical reviews, etc., to recreate these women’s specific personalities and stage personas. Planning on a technical level included reserving a space to perform, set up of sound, lights, props, set pieces, publicity, etc., and proved to be a necessary challenge to have our artistic ideas come to fruition. The result of our efforts was a thirty-minute cabaret entitled Girl’s Night Out: A Tribute to Women in Musical Theatre. The experiences from this production were individually rewarding for each performer. Most importantly we discovered how art, especially the performing arts, is a collaborative process that demands discipline, open communication, organization, commitment, flexibility, and artistic vision.

UCI Cargo Express Plane
Cang Lam, John Liu, Pauline Nyon, Kenny Phong, & Shirley Vong
Mentor: Dr. John LaRue

Each year, the Society of Automotive Engineers (SAE) hosts an event that challenges student engineers all over to design and construct a radio-controlled model cargo airplane. Restrictions on the engine size and wingspan offer more opportunity to apply our practical engineering knowledge learned in the classroom to specific situations and to manipulate the problem to facilitate a better solution. It involves working with the two aspects of flight performance as well as the accuracy of the design predictions. The design goal is to carry about twenty-five to thirty pounds of cargo weight, which is more than twice as heavy as the plane. The major design constraints limit the wingspan to six feet or less, and prescribe one of two specific engine choices. Thus, ultimately, our design translates into maximizing lift while minimizing weight and drag. However, given the structural requirements of the airplane, as the plane must remain structurally intact in flight and upon landing, weight cannot simply and blindly be subtracted and minimized. Rather, it must be optimized to balance the factors of lift as well as strength to withstand the aerodynamic and gravitational forces of air and land.

Monitoring High Methane Emissions at the Edison Park Landfill in Huntington Beach, CA
Julia Aponte, Gloria Liu, Marie Jennifer Lopez, David Medina, & Rishi Mhapsekar
Mentor: Dr. Donald Blake

Gas emissions from landfills are regularly monitored to ensure civic health and safety. Landfills are a major source of methane, which is used as a source of energy in many homes. Bacteria in the soil consume paper products from these landfills and give off methane. Methane levels from landfills are believed to increase as time progresses. At one landfill under Edison Park in Huntington Beach, CA, a gas monitoring company reported that levels of methane are decreasing over time. This company is currently under criminal investigation for falsifying data. Our group has found that the methane level in this landfill is substantially high. Background levels of methane are around 2-3 ppm, and using gas chromatography we analyzed various air samples at this landfill and found methane levels to be as high as 36 ppm. This excess methane, if not controlled, can become flammable, affecting the surrounding residential area and high school. Our study plans to continue monitoring the levels of methane and other gases like CO (carbon monoxide) at this landfill. We want to use the results to increase civic awareness about this problem of increased methane levels and also find a viable solution so that this excess methane can be used as a fuel source.

A Computational Study of Conformational Interconversions and Stereoelectronic Interactions in Silathiacyclohexanes (Silathianes)
Chansa Cha, Christine Fang, Angela Huang, Jee Hwang, & Patricia Louie
Mentor: Dr. Fillmore Freeman

Stereoelectronic hyperconjugative interactions and the relative energies and structures of conformers and transition states of 2-silathiacyclohexane (2-silathiane), 3-silathiacyclohexane (3-silathiane), and 4-silathiacyclohexane (4-silathiane) have been calculated using ab initio molecular orbital theory and density functional theory (DFT) with the 6-31+G(d,p) and 6-311+G(d,p) basis sets. Intrinsic reaction coordinate (IRC) calculations have been used to connect the respective transition states between the chair and twist conformers and the enantiomers of the respective twist conformers. All levels of theory calculated the chair conformer of 2-silathiane to be lower in energy than the chair conformers of 3-silathiane and 4-silathiane and B3LYP/6-31+G(d,p) calculated these energy differences (DE) to be 15.38 and 15.86 kcal/mol, respectively. B3LYP/6-31+G(d,p) calculated the respective energy differences (DE, kcal/mol) between the chair conformer and the 1,4-twist (DE = 4.16), 2,5-twist (DE = 3.20), and 3,6-twist (DE = 3.87) conformers of 2-silathiane. B3LYP/6-31+G(d,p) calculated small energy differences (DE, kcal/mol) between the chair conformer and the 1,4-twist (DE = 3.95), 2,5-twist (DE = 4.07), and 3,6-twist (DE = 3.46) conformers of 3-silathiane. HF/6-31+G(d,p) and B3LYP/6-31+G(d,p) calculated the energy of the transition state that connects the chair and 1,4-twist conformers of 3-silathiane to be 5.15 kcal/mol and 4.92 kcal/mol, respectively. B3LYP/6-31+G(d,p) calculated the respective energy differences (DE, kcal/mol) between the chair conformer and the 1,4-twist (DE = 3.55) and 2,5-twist (DE = 4.04) conformers of 4-silathiane. Relative energies of isomers and conformers will also be discussed.

A Novel Enzyme Linked Immunosorbent Assay (ELISA) that Measures Insulin Autoantibody (IAA) IgG Subclasses
Forough Ghavami Shirehjini, Mehraneh Jafari, Danielle Kushner, Talla Motakef, & Norela Ocampo
Mentor: Dr. Edward Arquilla

This study is founded on the need to develop a method that can measure human insulin autoantibodies (IAA) and immunoglobulin G (IgG) subclasses. This need is based on the fact that IAA IgG subclasses may be involved in blood glucose control, the complications that afflict diabetics, and the onset of human Type 1 diabetes. Yet, because of the deficiency of a consistent and valid method to measure IAA IgG subclasses, there is a paucity of documented evidence on the role that IAA IgG subclasses may have in controlling the blood sugar of insulin treated diabetics. Thus, the specific aim of this study is to develop a method to measure immunoglobulin G (IgG) human insulin autoantibodies (IAA) subclasses. There are two specific aims in this project: 1) To develop a very sensitive ELISA that will measure the total IgG concentration and the fractional distribution of each of the IgG subclasses in the peritoneal effluent of insulin treated diabetics and 2) To measure the fraction of the total IgG that is IAA and the amount of IAA in each of the respective IgG subclasses. To date, a very accurate and sensitive IgG ELISA has been developed. This assay’s validity has been established by comparing the total IgG and IgG 1 level in 18 serum samples to the total IgG measured by the nephelometric method currently used in our clinical laboratories and finding a highly significant correlation between the nephelometric and ELISA methods. Presently, preliminary investigations in stripping the insulin-IAA complexes in order to measure total IAA have been accomplished by dialyzing against guinea-pig antibodies and citric acid. The concentration of insulin allows for the calculation of the total IAA that is IgG, which has been found to be roughly 1%.

SAE AeroDesign West 2003
Young Huh, Trevor Orr, Greg Raith, Brandon Tabaldo, Terens Whelan, & Fazlul Zubair
Mentor: Dr. John LaRue

Everyday we take for granted the ingenuity and mechanical skill needed to create an airplane and keep it flying. The Society for Automotive Engineers (SAE) holds an annual competition each year to encourage students to design a cargo plane that can carry the greatest load. We are participating in the regular class competition, which has certain constraints, such as a wing span limit of 6 ft. To overcome this limit we decided to be innovative and create a tri-plane structure. A tri-plane is a design of airplane that sports three separate wing sections in a certain configuration that can generate a large amount of lift. To determine the best configuration for the tri-plane, we conducted research using NACA (National Advisory Committee for Aeronautics) reports done in 1924. The report written by C. Wieselsberger titled Triplane Tests was our main source of data for this project. Using this report we picked a tri-plane configuration that will give us high lift and stability in flight. Currently we are in the process of building our plane and we hope to do well in the competition in June. Through this project we hope to learn more about airplane construction and design and gain insight on how different wing configurations affect lift and drag. We are additionally testing high lift devices such as Gurney flaps and larger camber fuselages. Lastly we are testing different fabrication techniques that will be low cost and produce high-quality, strong airplanes, such as foam, fiberglass, composite, and molding techniques.

Stand Training Robot for the Clinic and Home

Mentor: Dr. David Reinkensmeyer

Over 600,000 individuals in the United States each year suffer a stroke that prevents their legs from performing the normal functions necessary to stand. Approximately 10,000 suffer a spinal cord injury that limits their standing ability. In order to train an individual to be able to walk again, we must first develop an affordable robotic system for assisting in stand training following the spinal cord injury. Patients can be taught to stand for extended periods of time with a promising new rehabilitation therapy. The major elements that are associated with this therapy are to provide a graded level of body weight support, and to assist with knee extension as necessary. The current standing frames do not dynamically assist in standing, but rather clamp the leg in an extended posture, doing away with the need for the nervous system to learn to control standing. An old adage gives an important background to how stand training is thought of: "A person must be able to stand before they can walk." It is our goal to assist in this necessary function for walking by building a robot that promotes stand training.

Hip Hop & Its Roots
Danielle Daguman, Christina Glur, Julia Hughes, Jennifer Magpantay, Richelle Mowry-South, & Greta Schroeder
Mentor: Dr. Bob Boross

The project, Hip Hop and Its Roots, has been Julia Hughes’ attempt at researching and presenting the history of hip hop dance. She began this project as her thesis for the Campuswide Honors Program and it has turned into a labor of love. She researched the evolution of hip hop dance from its beginnings in African dance through many forms until what hip hop has become today. She presented the dance forms (West African, slave dances, swing, rock’n’roll, break dancing, and hip hop) on April 18 and 19, 2003 at the Little Theater in Humanities Hall on the UC Irvine campus. The dance forms are presented as accurately as possible but to modern music, which is played by a DJ throughout the whole performance. There are also emcees that explain the transitions between the different types of dance in between each dance piece.

The Integration of Multiple Institutions into a Single Database

Mentor: Dr. Peter Lawrence

A report from the Institute of Medicine identified medical errors, which cause 98,000 unnecessary deaths, as a major healthcare issue. To address these errors, the first step is for each physician and institution to know the frequency of complications and deaths. The purpose of our study is to determine the current status of databases among vascular surgeons in the Western United States, determine the extent of interest among vascular surgeons in participating in a uniform database, and assess their information and resource needs. Using a modified Delphi technique, a questionnaire was sent to members of the Western Vascular Society (WVS) and Rocky Mountain Vascular Surgery Society (RMVSS). Additionally, we obtained three leading commercial vascular databases distributed primarily in the United States, as well as a shared database used by many vascular societies in Europe. The response rate to the questionnaire was 56.6%. We found four distinct databases in the United States and Europe: Vascular 2000 by MFS database, Vascubase version 4.8 by Consensus Medical system, Atrium version 2.0 by Atrium Medical, Inc., and Karbase. Ninety-three percent of physicians are willing to both enter data into a database on each patient and share the data with other physicians. The median time for data entry acceptable to these physicians is five minutes. These data confirm the willingness and resource commitment of vascular surgeons to improve patient data collection.

Senior Choreographic Thesis
Briana Bowie, Nicole Giordano, Nathan Hodges, Nolan Kubota, Piper Lewis, Natalie Penn, Kimberly Shimasaki, Sunny Staton, & April Tra
Mentor: Dr. David Allan

Over the last 4 years within his dance major, Nathan Hodges has focused his creative and artistic talents on choreography. By expressing his thoughts, opinions, and feelings through dance in both blatant and abstract forms, he has found both inspiration and meaning in personal and professional life. To Hodges, the entire choreographic process, including brainstorming, experimenting with movement, setting it on dancers, and watching it become something new and beautiful, is overwhelming and wonderful. It was his goal in his final year at UCI to reset all his past dances and to choreograph a few new ones and combine them into an evening that would feature his entire repertoire. He hopes to not only show his growth as a choreographer and to exhibit his art, but to learn from this entire process everything that will be necessary for his future professional career. The performing piece, "The Benefits of a Catholic Education," is an excerpt from Sunny Staton’s and Hodges’ thesis show and was the first of his dances, originally performed in Physical Graffiti 2001. The dance is a summary of the angst and anger Hodges and his friends felt while attending Catholic high school during their freshman year. The piece touches on how adolescent development is affected in a structured institution that is founded on religion.

Professional Performance Experience in Concert Jazz Dance Studies
Carla Cardona-Robbins, Noemy Hernandez, Julia Hughes, Marc Macaranas, Jennifer Magpantay, Richelle Mowry-South, Spencer Smith, Mia Velez, & Mandarin Wu
Mentor: Dr. Bob Boross

The objective of this project was for the dancers involved to gain professional performance experience in jazz dance. To do this, the UC Irvine Jazz Dance Ensemble participated in Spectrum Dance LA on November 23 and 24, 2002 at the Ivar Theater, a historic theater off Sunset Boulevard in Los Angeles. We performed a new, experimental piece choreographed by Bob Boross entitled, If There’s A Hell Below, We’re All Gonna Go. This piece utilized the revolutionary actor’s training method Viewpoints to allow the dancers to improvise realistic crowd scenes during the course of the dance, possibly the first time this method has been used in concert jazz dance. Being one of 15 dance companies participating in this performance gave us the opportunity to see other forms of jazz dance that are popular in Los Angeles, make contacts in the dance world, and get feedback from professional dancers, choreographers, and reviewers. We received a mention in reviews in the Los Angeles Times and the Beverly Hills Reporter.

BattleBots is an increasingly popular robotic sport with an annual competition in May. Founded by Trey Roski and Greg Munson in March 10, 1999, there is now an abundant amount of people who have continued their interest in this sport. This tournament not only interests the engineers and the mechanics, but also encompasses all majors and people alike. In a competition of fierce battle and perseverance, a grueling one-on-one match comes down to one factor: the best creatively built armored and weaponed bot. Two teams of Mechanical Engineering students at UCI are inspired and actively enthusiastic to have the opportunity to outwit and outlast any competition pitted against them. We are challenged to design, build and control a robot that will prevail over all others through our creativity, engineering skills, strategy, and driving ability. We are currently building our robots based on our design drawings and striving to make them undefeatable. As we progress further into the project we will accumulate experiences that mirror the industrial field of problem solving and critical thinking.

Mentor: Dr. Donald McKayle

Dink’s Blues is the female solo from Rainbow Round My Shoulder, created in 1959 for a company of seven men and one woman, set to the rich soulful songs which the men sing as they toil. This work, hailed as a modern dance classic, is set on a chain gang in the American south where the prisoners labor "from can see to can’t see," breaking rocks with pick axes in the hot sun. As they work, they dream of freedom; it comes to them in the guise of a woman. The solo will be performed by Piper Lewis and the choreographer was Donald McKayle. The music is from traditional chain gang songs, which are from the collection of John and Alan Lomax, and they are arranged by Robert De Cormier and Milton Okun. Costume design was by Domingo Rodriguez.

The Formula SAE research project is an annual opportunity for students in various disciplines to research and design an open-wheel vehicle based on very few regulations. This study builds upon the work of previous Formula SAE research as well as formal research from various sources including the Society of Automotive Engineers. The primary stages of research include an extensive study of the ergonomics of driving. Four average-sized people were placed into a simulation cockpit and asked to report their most comfortable and most responsive seating positions. Further research was done on suspension geometries as well as four-stroke combustion engines in order to economically improve the performance of the vehicle. Computer-based simulation programs were used to analyze the structure of the chassis as well as visually analyze the vehicles dynamic motion. Following these analyses, a prototype was built according to our designs and data was collected regarding the vehicle’s dynamic performance as well as the driver’s comfort level and fatigue after extensive driving.
