Purpose: The study assessed the effects of a 12-session empowering program to promote health quality of life, decision making self-efficacy, self-care competency, and reasonable medical care utilization among low income women households in one rural area. Methods: A quasi-experimental, one-group pre-posttest design was employed. A total of 28 women enrolled as medicaid recipients in the Public Health Center of W city agreed to participate. The empowering program consisted of 12 sessions addressing health education for self-care of disease, medication management, and counseling for psycho-social support. The intervention was delivered by five nurses and one social worker. Women completed a structured questionnaire measuring the study variables with demographic characteristic before and after the intervention. Data were analyzed by PAWS Statistics 17 utilizing descriptive statistics and paired t-test. Results: After the intervention, significant increases were evident in participant health quality of life (t=-5.83, p<.001), decision making self-efficacy (t=-4.86, p<.001), self-care competency (t=-8.16, p<.001), and reasonable medical care utilization (t=-3.97, p<.001). Conclusion: The 12-session empowering program on health quality of life as well as self-care competency was effective when delivered to low income women households. Further studies with larger numbers of participants and a control group are necessary to validate the results.

In order to analysis of the water pollution of the Anyang stream(one of the biggest branch streams of the Han River) and its main tributaries, the geological and topographical and rainfall features in its basin were investigated. To do this, the water samples were collected 23 points of the upper, mid and down of Anyang stream and its tributaries and were analyzed based on the chemical methods, Korean Biotic Index(KBI) and Saprobien systems. The Anyang stream basin has a characteristic of topographical torrential heavy rainfall like a typical rainfall feature in Korea. The concentration and the outflow rate of rainfall is very different in seasonal, and water pollution in dry season is especially severe. After 1997, although the water quality status of stream has been improved gradually, the concentration of T-N and SS at the upstream is increased due to the deficiency of facility used for collecting wastewater released from industrial factories, livestock farms and residential areas. The mainstream of the Anyang stream is classified into the 5th grade water as polysaprobic water area according to Saprobien system and the biotic index is over 2.5 in overall. Most of tributaries have 1~3 grade water limit with ${\alpha}$- and ${\beta}$-mesosaprobic except the upper and mid streams of Samsung tributary, in which pollution status is the lowest part. Though Sambong tributary is ${\alpha}$-mesosaproboic, biotic index is low because of the appearance of abundant benthos animals in farming and fishing villages.

Acute hemodynamic effects of CJ-18513, a non-peptide angiotensin IIreceptor antagonist, were examined in mongrel dogs treated with high frequency ventricular pacing for one week. Rapid ventricular pacing reduced mean blood pressure (mBP), Lvdp/dt and cardiac output (CO), and increased the left ventricular end-diastolic pressure (LVEDP) and pulmonary capillary wedge pressure (PCWP). Continuous infusion of CJ-10513 at doses of 10 and 20$\mu$g/kg/min, respectively, for 30 minutes reduced mBP, LVEDP and myocardial oxygen consumption rate (MVO,) and shifted the cardiac function curve (CO-LVEDP ourve) to the left in this dog model. In conclusion, CJ-10513 decreased the preload and afterload and increased the cardiac function in dogs with pacing-induced heart failure.

Purpose: The purpose of the study was to identify the effect of a self-exercise program on low back pain, abdominal-back muscle strength and waist flexibility in hospital nurses. Method: An experimental research design was employed. 43 subjects (20 in the experimental group and 23 in the control group) who worked in a general hospital in W city agreed to participate in this study. The intervention had 6 sessions with self-exercise program including flexion and extension demonstrated by a trained research assistant. A Visual Analog Scale was used to measure the subjective pain severity. Abdominal-back muscle strength was measured with a back strength dynamometer, while waist flexibility was gauged by the standing of the subject's upper body. Analysis included descriptive statistics, $x^2$ test, t-test and ANOVA. Result: The experimental group exhibited significantly decreased low back pain, an increase in abdominal-back muscle strength, and increased waist flexibility after 6 sessions. The experimental group were not significantly increased in abdominal-back muscle strength than the control group. Conclusion: These results suggest that further research is needed to replicate for verification of clinical validity with the methodological rigors, and to utilize the self-exercise program for care and prevention of low back pain.

Purpose: The purpose of the study was to identify the relationship between obesity and bone mineral density in middle aged women. Methods: A cross-sectional survey design was utilized with a check list and physiological measurements. A total of 827 convenient samples were recruited from women who lived in the community. Bone mineral density was measured by T-score using the pixi method of Lumar on the left heel. Descriptive statistics and pearson correlation coefficient were utilized for data analysis. Results: Most were assessed as having normal weight(37.9%) or obese (57.4%) by BMI. Only 32% was assessed as having normal bone mineral density, while 40.3% had osteopenia, and 27.7% as osteoporosis. The BMI scores were significantly related to age, and episodes of fractures. Those with lower bone mineral density reported significantly more episodes of fractures and chronic disease. The T scores of Bone mineral density were significantly correlated with the scores of BMI (r= .126, p< .001). Conclusion: There is a strong need to develop intervention programs for this age group to manage bone mineral density loss to prevent occurrences of osteoporosis, and episodes of fracture.

The purpose of this study was to provide the basic information for developing sugar related nutrition education programs for children in child-care facilities and their parents. The results showed that the total score of parent's dietary attitudes towards sugar-rich foods was 17.94 and the total score of parent's nutritional knowledge was 3.67. A positive relationship was observed among items of parent's dietary attitudes (p<0.01), and some correlations were also observed between the total score of parent's nutritional knowledge and the total score of parent's dietary attitudes (p<0.05 or p<0.01). The total average score of children's eating behaviors for sugar-rich foods was 23.98, and the item with the highest score was 'I often eat candy, chocolate and jelly'. For children, food that received the highest preference was chocolate, and soft drinks received the lowest preference. The most frequently consumed food item was candy or caramel, and the least frequently consumed food item was soft drinks. There were positive correlation among the total score of children's eating behaviors, food preferences, and food intake frequency (p<0.01). When parent's tried to reduce the sugar intake, children's total score of eating behaviors (p<0.001) and food intake frequency (p<0.001) for sugar-rich food was lower. We conclude that parent's dietary attitudes may influence children's eating behaviors, food preferences, and food intake frequency for sugar-rich foods.

Purpose: The study was done to examine the effects of cognition-behavior integrated breast cancer prevention education, in which a breast model with interchangeable nodules was utilized, on the self-competency of nursing students in performing breast cancer education. Methods: A nonequivalent control group non-synchronized design was used. A traditional lecture intervention was provided for 49 3rd year college of nursing students (control group) while the integrated breast cancer prevention education was given to 47 3rd year students in the same college one year later (experimental group). The integrated breast cancer prevention education was developed by the research team to strengthen the competency of cognitive and behavioral components in education on breast cancer. Results: Effects of the intervention were found to be significant through all study variables: knowledge about breast cancer (t=7.79, p <.001), breast cancer risk awareness (t=2.05, p <.05), self-competency of breast self-exam (t=8.27, p <.001), and intention to teach breast self-exam (t=3.87, p <.001). Conclusion: The integrated breast cancer prevention education was useful to improve not only knowledge about breast cancer but competency in performing breast examination for nursing students who acquired technical skills from various simulation nodules. As the program helped the students to be prepared as confident educators, future application of the module is recommended for academic curricula.
