Minority populations in the United States have a higher prevalence of non-insulin-dependent diabetes mellitus (NIDDM) and more persons die of the disease than white persons. This study was to review and compare risk factors and prevalence rates of NIDDM in African Americans, Hispanic s, Korean Americans and Native Americans in the United States. The risk factors of NIDDM, including family history of diabetes, obesity, physical inactivity, diet and age, were reviewed in the minority populations. Risk factors such as obesity, physical inactivity and family history of diabetes occurred to a greater extent in some minority populations than in the white population. Diabetes should be treated as a public health problem for minority populations. Due to the increase of older populations and the increased prevalence of obesity and sedentariness, NIDDM in minorities is nearing epidemic proportions. Good diet and regular exercise can reduce the incidence of NIDDM but an understanding of the cultural aspects of diabetes is imperative in order to provide adequate community health education programs because those programs involve diet and behavior changes, characteristics that are often culturally determined. In summary, it is important to plan a community health education program targeted on NIDDM in a culturally adapted manner that will be received with both comprehension and acceptability. In particular, the program for high-risk populations should be stressed so to prevent diabetes. Preventive approaches to diabetes should be considered because they can be both therapeutic and cost effective.

In this study, we have purified and characterized the membrane bound nitrate reductase obtained from the denitrifying bacteria, Ochrobactrum anthropi SY509, which was isolated from soil samples. O. anthropi SY509 can grow in minimal medium using nitrate as a nitrogen source. We achieved an overall purification rate of 15-fold from the protein extracted from the membrane fraction, with a recovery of approximately 12% of activity. The enzyme exhibited its highest level of activity at pH 5.5, and the activity was increased up to $70^{\circ}C$. Periplasmic and cytochromic proteins, including nitrite and nitrous oxide reductase, were excluded during centrifugation and were verified using enzyme essay. Reduced methyl viologen was determined to be the most efficient electron donor among a variety of anionic and cationic dyestuffs, which could be also used as an electron donor with dimethyl dithionite. The effects of purification and storage conditions on the stability of enzyme were also investigated. The activity of the membranebound nitrate reductase was stably maintained for over 2 weeks in solution. To maintain the stability of enzyme, the cell was disrupted using sonication at low temperatures, and enzyme was extracted by hot water without any surfactant. The purified enzyme was stored in solution with no salt to prevent any significant losses in activity levels.

In this study, the optimization of fabrication conditions was accomplished to make immuno-strip biosensor by the combination of enzyme linked immunosorbent assay (ELISA) and immuno-chromatographic strip techniques for the detection of Escherichia coli O157 : H7. Optimal fabrication conditions of capture antibody concentration, detection antibody concentration, and additive composition of running buffer solution were determined. Optimal concentration was determined as 1.0 mg/mL for both of capture antibody and detection antibody. A composition of 0.5% Tween20 and 3% BSA were selected as optimal additive for buffer solution to prevent non-specific binding.

This is a descriptive study that introduces programs that support family caregivers looking after the elderly, by focusing on the case of Georgia, in the United States. The U.S. is one of the few countries that support family caregivers by law. In this study, we focus on the evidence-based interventions implemented through the Alzheimer's Disease Supportive Services Program (ADSSP), a federal policy that complements the National Family Caregiver Support Program (NFCSP). Our findings show that one-on-one evidence-based programs (EBPs) for family caregivers are both economical and effective in assisting caregivers. In our discussion, we highlight how the implementation of the latest EBPs can build an infrastructure to support family caregivers. ADSSP funding is useful as it constructs a caregiver support through the implementation of programs in the local community. The result is the creation of a well-coordinated division of labor among government agencies, academia and NGOs, which produces a synergetic effect in funding, research and development, translation and implementation of programs, and staff training. We conclude that the implementation of EBPs funded by the government is a useful reference for Korea and other rapidly aging countries, if we are to create an infrastructure for caregiver support, which can effectively prevent a crisis in caregiving.

Purpose: The purpose of this study was to analyze the prevalence of allergic disease among elementary school students in rural and urban areas. Methods: In this study, 1,513 elementary students (1,163 in urban areas, 350 in rural areas) were surveyed. Data were analyzed using frequency, percentage of allergic symptoms and $X^2$ test was used to identify differences in the prevalence of allergic symptoms between urban and rural area students. The SAS program was used in the data analysis. Results: There were significant differences in the prevalence of allergic disease according to whether there was a family member with a prior history of allergy symptoms. 48.7% of surveyed students (49.4% in urban, 46.3% in rural) had allergic symptoms. Allergic rhinitis was the most frequent allergic symptom in both urban and rural students. Conclusion: These results suggest that there is a need to prevent and manage allergies among elementary students. The family history should be considered an important factor when a program for allergy prevention and management is developed. Interventions are needed in both areas, especially for students with allergic rhinitis.

In this study, $Si_3N_4$/SnZnO/AZO/Ag/Ti/ITO multi-layer film were prepared on glass substrate by DC/RF magnetron sputtering method. To prevent interfacial reaction between Ag and ITO layer, Ti buffer layer was inserted. Optical properties and sheet resistance were studied depending on laminating times of each multi-layered film especially in visible ray. The simulation program, EMP (essential macleod program), was adopted and compared with experimental data to expect the experimental result. It was found out that the transmittance of the first stacked $Si_3N_4$/SnZnO/AZO/Ag/Ti/ITO multi-layer film was more than 90%. However, with increasing stacking times, the optical properties of $Si_3N_4$/SnZnO/AZO/Ag/Ti/ITO multi-layer film get worse. Consequently, Ti layer is good for oxidation barrier, but too many uses of this layer may have an adverse effect to optical properties of TCO film.

Purpose : The purpose of this study was investigated to find the approach in the PNF and TC for frail elder Method : This is a literature study with books, articles, seminal note and books for PNF and TC international course. Result : Neural mechanisms contribute significantly to the gains that occur in the range of motion about a joint with stretching exercises. The participation in a stretch-training program decreases tonic reflex activity and increases flexibility and decreases in force production and muscle activation. Also the stretching-induced decreases may be due to a central nervous system inhibitory mechanism. PNF stretch techniques can increase ROM in older adults. These results may differ from those of studies performed with younger populations because of age-related physiologic changes. TC exercise improves balance control and muscle strength and were associated with reorganized lower extremity neuromuscular patterns. Conclusions : The stretch training program of the PNF and TC contribute to increase the balance and coordination for frail elder. Therefore, The frail elder prevent falling. Further study, The PNF and TC be introduced as the new therapeutic intervention for frail elder.

Purpose: This study was to assess the degree of infection prevention behaviors at home, and a relationship between those behaviors and barrier factors among cancer patients undergoing chemotherapy. Method: The data were collected from 92 cancer patients who were undergoing chemotherapy with more than two kinds of immunosuppressive agents at G university hospital in J city from February 17 to April 4, 2003. The instruments were the infection prevention behavior scale developed by researchers and the barrier factor scale by Gu et al. (2003). The data were analysed using mean, standard deviation, t-test, ANOVA, and Pearson's correlation coefficient by SPSS program. Results: The mean score of the behaviors for infection prevention was 2.61 of 4. The highest score was on the subscale 'rest and exercise', and the lowest score was on the subscale 'monitoring sign and symptom of infection'. And a negative correlation(r= -.208, p= .023) was found between infection prevention behaviors and barrier factors. The barriers correlated to infection prevention behaviors were mainly 'no habits' and 'no interest'. Conclusion: It seems that the degree of the behaviors for infection prevention was not performed enough to prevent infection among cancer patients. And there was negative relationship between infection prevention behaviors and barriers. We suggest to develop a nursing intervention program to enhance infection prevention behaviors through reducing the barrier factors.

Purpose: This study was conducted to identify the relationship of the elder abuse perception with the caregiving stress of adult caregivers and to investigate influencing factors on them. Methods: Data were collected from 398 adults aged 30-65, and analyzed with the SPSS/WIN program. Results: In the elder abuse perception, there were differences in age, marital status, education, job, person to be taken care of, age of elderly mother, duration of caregiving, economic status and health status of elderly parents. As for the caregiving stress, there were differences in age, marital status, income, health status, relationship with the elder, person to be taken care of, economic status and health status of elder parents. Influencing factors on the elder abuse perception included caregiving stress, education, marital status, health status of elders, and economic status of parents (30%). On the caregiving stress, elder abuse perception, economic status of elders, and relationship between caregivers and elders were influencing factors (24%). Conclusion: The results of this study suggest that it is needed to develop a nursing program to prevent elder abuse and to decrease caregiving stress in caregivers. In addition, it should be considered in tandem with significant influencing factors that were found in this study.

Purpose: This study was to explore factors affecting musculoskeletal symptoms of the child care centers' teachers in Korea. Methods: This study was a descriptive research, using a cross-sectional survey. Convenience samples of 230 child care centers' teachers aged 20 to 65 were selected. A self-administered questionnaire was used to measure general characteristics, job-related characteristics, exercise habit, fatigue and musculoskeletal symptoms of the body parts. The data were analyzed with the SPSS/WIN 21.0 program. Results: Shoulder pain (73.5%), low back pain (72.6%) and wrist/hand pain (57.8%) were the most common musculoskeletal symptoms. Shoulder pain significantly differed depending on the age of children in charge at the child care center (p<.047). The exercise habit was related to low back pain (p<.028) and the career was linked to wrist/hand pain (p<.046). The logistic regression analysis revealed exercise habit and fatigue were the risk factors on musculoskeletal symptoms of many body parts. Conclusion: These results suggest that interventions targeting the child care centers' teachers should be considered job-related characteristics and fatigue in order to prevent musculoskeletal disorder. Thus, there continues to be a need to develop exercise program for the child care centers' teachers.
