computer and photography industries may benefit from a new invention developed
by a UNT research group led by Oliver Chyan, Ph.D., associate professor
A patent was recently granted for the ultra-sensitive chemical sensor
that detects minute metallic impurities. In the semi-conductor industry,
the silicon-based sensor can be used in integrated circuit production
to prevent losses due to unpredictable contamination. In the photography
industry, the sensor can help determine that photo-processing chemicals
have been purified before they are released into the environment.
Chyan's work was funded by Texas Instruments for more
than $300,000 over a six-year period and by Kodak for $150,000 over two
and a half years.
conducted by William E. Moen, Ph.D., assistant professor of library and
information sciences and a fellow at the Texas Center for Digital Knowledge
at UNT, will make retrieving information from library catalogs and other
online databases easier. It involves the use of the American National
Standard Z39.50, a computer communications protocol for information retrieval.
The protocol is widely used in the software of libraries and other organizations
that provide online searching of their databases.
To improve how Z39.50-accessible systems work together,
Moen received a $280,000 National Leadership Grant from the U.S. Institute
of Museum and Library Services. The grant, along with contributions from
OCLC, SIRSI Corp. and Sea Change Corp., funds the research and demonstration
of a Z39.50 interoperability testbed. Vendors, developers and libraries
will use the testbed to assess how well their Z39.50 systems are configured.

Hans Schaeuble's opera Dorian Grey for a full-scale world premiere
production and recording in February 2003.
The Swiss Schaeuble Foundation awarded UNT a grant
of $65,000 to fund the production, which is being mounted as a partnership

A team of faculty members and students from the School
of Community Service and the School of Visual Arts is hard at work creating
a multimedia CD-ROM for sixth- through ninth-graders that will help them
understand why they shouldn't smoke.
The project was funded by a $355,573 grant from the
Nursing, Allied Health and Other Health-Related Education Grant Program,
established by the Texas Legislature with proceeds from the 1998 Texas
tobacco lawsuit settlement. Free copies of the CD-ROM and accompanying
manual will be provided to every middle and junior high school in Texas
Texas Center for Educational Technology within the College of Education
is now entering the second year of a multimillion-dollar grant supporting
teacher education in technology.
State funds exceeding $5 million are allocated to UNT
for the Intel Teach to the Future project, a worldwide initiative training
classroom teachers to integrate the use of computers into their curriculum
to improve student learning. Microsoft Corp. and other technology-related
companies also provide support.
Over the four years of the project, 400,000 classroom
teachers in 20 countries will be trained. A recently approved grant from
the Texas Telecommunications Infrastructure Fund Board will help UNT and
Texas A&M University double the impact of the effort in Texas.
Connors, Ph.D., nutritionist and assistant professor of merchandising
and hospitality management, is profiling school menu writers to better
understand their food choices. In collaboration with the Texas Department
of Human Services Special Nutrition Program, she is determining if the
menu writers' training, attitudes toward reducing fat and familiarity
with food safety techniques influence school menu selections.
She found that although many menu planners were avoiding
in their own diets, the menus they wrote for children were high in fat
— despite U.S.
Department of Agriculture mandates to reduce fat in school meals. The
study will be used to help menu writers become better educated in nutrition
and safe food handling.
who are racial minorities in their churches are more supportive of tax
breaks for businesses in minority areas, legal immigration and interracial
marriage than Caucasians who attend churches in which they are the racial
majority, according to research conducted by George Yancey, Ph.D., assistant
professor of sociology.
Yancey received $484,884 from the Lilly Endowment to investigate whether
Americans who are members of multiracial churches have less racial prejudice
than those who are not members of multiracial churches.
He also discovered that African Americans were more
supportive of immigration if they were the minorities in their churches
and more supportive of interracial marriage if they attended multiracial

Craig Neumann, Ph.D., assistant professor of psychology,
says understanding the "time-of-day" effect on performances
caused by circadian rhythms could be particularly helpful in the treatment
of patients with schizophrenia, who tend to have attention deficits with
and without medication and who have cognitive defects.
Neumann received $60,000 from the National Alliance
for Research on Schizophrenia and Depression to conduct time-of-day studies
on 50 patients at the Dallas Veterans Affairs hospital.
research has shown that people with depression often complain about not
understanding others' speech. This may be caused by low levels of serotonin,
a neurotransmitter involved in stimulus reactivity and sensory reception
that produces feelings of calm and well-being.
Kamakshi Gopal, Ph.D., associate professor of speech
and hearing sciences, is testing the hearing and speech perception skills
of people who have been medically diagnosed with depression. She plans
to test the subjects before and after they are on medication to increase
their serotonin levels, and compare the results with subjects who do not

how the body's immune response helps protect against spreading cancers
is the focus of intensive research at the Health Science Center. Ronald
Goldfarb, Ph.D., director of the Institute for Cancer Research, and his
team of researchers demonstrated how a specific type of white blood cells,
aptly named natural killer cells, travel through the body to invade advanced
The researchers have been able to stimulate these natural
killer cells to enhance their lethal effect on malignant tumors and improve
their effectiveness in hunting cancerous cells with quick and deadly accuracy.
Since the initial discovery, the team has focused on using its findings
to develop new drug therapies for advanced cancer.
Eisenberg, Ph.D., director of the DNA Identity Laboratory, is leading
his research team at the lab on a quest to automate the process of extracting
DNA from evidence.
Successful DNA analysis can mean the difference between
an unsolved crime and a closed case, but too few trained specialists and
too many cases have led to a national backlog of unsolved cases. Crime
labs currently analyze only 25 percent of the sexual assault cases reported
to authorities in the United States.
An automated extraction system will produce better and
faster results and is essential to solving more crimes based on DNA evidence,
UNT Health Science Center excels in recruiting minority students while
many other institutions are struggling with diversity issues. Its efforts
have earned the center national recognition as a role model institution.
Outreach efforts of the Graduate School of Biomedical
Sciences contributed to an increase in minority students while national
enrollment figures were declining. Thirty-six percent of the students
entering the graduate school in Fall 2001 are under-represented minorities.
The center also leads all other health science centers
in Texas in the percentage of minority students seeking graduate degrees.

food and little, if any, physical activity have contributed to a growing
rate of diabetes and signs of heart disease among young people. A research
team led by Ximena Urrutia-Rojas, D.P.H., assistant professor in the School
of Public Health, and pediatrician John Menchaca, M.D., is working with
local families to reverse the trend.
Initially, researchers found that nearly a quarter of Fort Worth fifth-graders
surveyed were at high risk for developing diabetes. Now the team is encouraging
individual families to adopt healthy lifestyles. Solutions that involve
the whole family tend to be the most successful since family members often
share similar eating and exercise habits, Urrutia-Rojas says.

Science Center graduates are helping alleviate the shortage. The Texas
College of Osteopathic Medicine actively encourages its medical students
to enter family practice.
A third of the graduates from the center's class of
2001 entered family-practice residencies. No other medical school in Texas
topped the 25 percent mark. Samuel Coleridge, D.O., chair of family medicine,
says the school is committed to producing the family physicians of tomorrow.
physicians will be better able to measure the effectiveness of manipulative
treatment, the hallmark of their profession, as a result of research being
conducted at the Health Science Center. With support from the National
Institutes of Health, the center is training osteopathic physicians in
how to conduct clinical research in osteopathic manipulative medicine.
Scott Stoll, D.O., Ph.D., chairs the Department of
Manipulative Medicine. This expanded and improved program allows the center
to continue to develop future researchers capable of competitive clinical
and basic science research in osteopathic manipulative medicine.
