Purpose : To provide data on exercise prescription for obesity management and prevention of cardiovascular disease in girl's high school and to prepare basic data for more effective exercise program for lifestyle improvement and prevention of lifestyle-related diseases. This study examines the effects on brain nerve growth factor and inflammatory factors, and the relationship between obesity factor and brain neuron cell production factor and inflammatory factor changes by complex exercise. Methods : The subjects of the study were obese students with a body fat percentage of 30 % or higher after obtaining body fat percentage of high school girls in C-city. Among them, 20 students who wanted to participate in the program of this study and did not participate in special exercise and diet therapy within the last 6 months were radio-sampled into groups of exercise group and control group, but attendance rate was low and The final exercise group (9) and control group (9) were measured, except for one student who did not respond. Results : Analysis of the range of variation in body composition, BMI, lean body mass, and the interaction between the groups showed significant differences (p<.05). TC, TG, HDL-C, and LDL-C as variables of blood lipids, TC and TG were not significantly different and TG was significantly different (p<.05) in interactions. HDL-C showed a significant difference (p<.01) in interactions, an increase in exercise group, and a significant decrease in control group (p<.05). There was a significant difference (p<.05) in BDNF interaction, an increase in the exercise group and a decrease in the control group, but no significant difference. NGF tended to increase in both exercise and control groups. IL-6 had a significant difference in timing (p<.05) and significantly decreased (p<.01) in the exercise group, and TNF-α interacted with timing (p<.05), and a significant increase in the control group. Conclusion : This study confirmed 12-week compound exercise program was effective in increasing the expression of basal fitness or CNS factor, but not enough to actually improve brain function. Fat mass and obesity are also affecting vascular inflammatory factors.

This study was conducted to determine the effects of dietary low grade soybean, fermented with Aspergillus oryzae (FSB 1) or Bacillus subtilis var. natto (FSB 2), on egg production and quality, fat and cholesterol content, and the fatty acid (FA) profile of eggs by lipid layer. A total of 18 Hi-Line strain layers, 22 wk of age, were randomly assigned to three dietary treatments: no fermented soybean (control), control with 15% FSB 1 (C + FSB 1), and control with 15% FSB 2 (C + FSB 2). The rate of egg production and egg weight were evaluated between two periods: one was from the 1st to 4th wk and the other was from the 5th to 8th wk. At the 8th wk, a total of 30 eggs were randomly selected from each treatment group and analyzed for physical quality, fat content, fatty acid composition and cholesterol content. The results showed that egg production was increased in hens fed with diets containing fermented soybeans from the 5th to 8th wk period (p<0.01). A similar tendency was observed through eight weeks' cumulative egg production (p<0.05). There were no significant differences in egg production between the C + FSB 1 and C + FSB 2 treatment groups (p>0.05). Egg weight and other physical properties did not vary between treatment groups (p>0.05). Egg yolks among different treatment groups were similar in fat content, but egg yolks in the C + FSB 1 and C + FSB 2 groups had lower oleic acid (p<0.05), higher linoleic, ${\alpha}$-linolenic, and arachidonic acids (p<0.01), and lower cholesterol content (p<0.05) than those in the control group. In conclusion, supplementation of fermented low grade soybeans might be useful as a functional feedstuff to improve egg production and quality for a healthy human diet.

Background : The goal of this study was to examine the health behaviors of nurses and provide basic information on health promotion for nurses. Materials and Methods : A self-administered questionnaire survey was completed by 340 nurses working at a university hospital in Daegu, Korea from March 6 to March 30, 2006. The questionnaire included demographic characteristics, working environment, health behaviors, self-assessed health status, and the practice of health promotion activities according to the work group(shift group vs. non-shift group). Results : There were significant differences in 'regular diet', 'drinking', 'ordinary health management', 'regular exercise', 'leisure activities', 'rest', and 'feeling of fatigue' between the two groups. The score for the practice of health promotion activities of the non-shift group was 121.9, which was higher than the 115.4 for the shift group. By field of practice of health promotion activities, there were significant differences in 'self-realization' and 'nutrition' between the two groups. Conclusion : The shift group did not appear to have enough time to take care of their health. It is therefore important to provide a working environment in which nurses are encouraged to increase their interest and efforts to maintain healthy behaviors. In addition, programs for education and training should be developed to help nurses adopt healthy life styles and enhance their self-esteem.

The cause of essential hypertension is yet unknown, but in general is caused by interaction of hereditary factors, diet, obesity, lack of exercise and stress. The aging process influences various physiological mechanism related to regulation of blood pressure. So elderly hypertensives have a tendancy to consider the disease as a result of the physiological aging process. This attitude causes many complications, worsening of the disease and even early death because of inappropriate care. In order to improve self-management of elderly hypertensives in this study the researcher examined the effect of blood pressure regulation by an education program that improves self-care behavior, through increasing self-efficacy. The education program consisted of group education on hypertension and self-care strategies, and encouraging and reinforcing self-efficacy resources such as verbal persuation, performance accomplishment and vicarious experiences. A quasi-experimental pre-and post-test design was used. Thirty-two elderly hypertensives participated in the study. Eighteen in the education group and fourteen in the control group. The education program consisted of eight sessions twice a week for four weeks. There was no intervention for the control group. Data were analysed using SPSS for Windows(Version 8.0). The results were as follows. 1. There was a significant decrease in systolic and diastolic blood pressure between the experimental group and control group over three different times, and interaction by groups and over time. 2. There was no significant difference in the level of self-care behavior between the experimental group and control group over three different times, and interaction by groups and over time. 3. There was significant difference in selfefficacy of experimental and control group, depending on the measuring period, but there was no difference between these groups on interaction by groups and over time. 4. There was positive correlation between self efficacy and self care behavior depending on the measuring period. There was negative correlation between diastolic blood pressure and self-care behavior on the posttest of the program, and between systolic blood pressure and self-care behavior on the follow-up test of the program. Findings indicate that this study will contribute to develop nursing strategies for the regulation of blood pressure for the elderly, which is easy for the elderly to learn as a nonpharmacologic approach.

The aim of this study was to investigate the latent classes and predictors of chronic diseases such as hypertension, dyslipidemia, arthritis, thyroid disease, depression, atopy, allergy, and diabetes. The subjects of this study were Korean citizens who participated in the Korea National Health and Nutrition Examination Survey in 2014. Stratified cluster sampling method was used with a sample size of 7,550. Latent hierarchy analysis was applied to this data. Four classes were identified. Class 1 consisted of participants with hypertension and diabetes. Class 2 consisted of participants with atopy and allergies. Class 3 consisted of participants with dyslipidemia, arthritis, thyroid disease, and depression. Class 4 consisted of participants without any chronic diseases. In comparing Class 1 to Class 4, age, physical activity, self-management, obesity, and presence of high cholesterol were found to be significant. In comparing Class 2 to Class 4, gender, age, and education level were significant. When Class 3 was compared to Class 4, gender, age, pain and discomfort, as well as high cholesterol were found to be significant. Diabetes and hypertension should be treated as comorbid conditions, applying integrated treatments involving effective drug treatment, diet, and physical activity programs. Atopy was found to be strongly correlated with allergies. Thyroid disease was found to coexist with dyslipidemia and arthritis, along with having a strong correlation to depression. Age-appropriate preventive measures can help reduce the risk of chronic diseases.

Objective: Incorporating high fibre ingredients into pig diets has the potential to reduce odour emissions from of pigs. The current study was carried out to determine effect of diets containing 0, 80 and 160 g/kg of each of lucerne hay, maize cobs and sunflower husks on the chemical characteristics and odours from pig slurries. Methods: Twenty eight pigs averaging $18{\pm}2.0kg$ were kept in individual cages, over four weeks. All pigs were fed ad libitum. Faeces and urine were collected, mixed in a 1:2.3 ratio (w/w), stored and fermented for 16 days in a temperature controlled room at $22^{\circ}C{\pm}2.3^{\circ}C$. The slurry was sampled twice (on day 1 and on day 16) of the fermentation period and analysed for pH, chemical oxygen demand (COD), nitrogen and short chain fatty acids (SCFA) concentration, on wet basis. All samples were tested for odour offensiveness using 18 panelists. A scale of 1 to 5 was used to rank the odour severity, (1 = not offensive, 5 = extremely offensive). Results: Slurry pH and COD varied with fibre source (p<0.05). On day 16, COD for lucerne hay, sunflower husk and maize cobs were 369, 512, and 425 (standard error of the mean = 34.2) mg of oxygen per litre. Total SCFA concentration was higher at day 16 than day 1 (p<0.05). Odour offensiveness varied with fibre source across both incubation periods (p<0.05). Sunflower husks and lucerne hay-based diets were rated as less offensive (mean rank = 2.2) than maize cob diets (mean rank of 4.3) (p<0.05). Conclusion: It was concluded that different fibre sources and incubation period influence chemical composition and odour of the slurry. There is, thereby, a need to incorporate locally available fibrous feeds in the diet of pigs because they have an economical and environmental relevance to pig management.

The purpose of this descriptive study was to identify the homecare needs of patients with cancer and to provide a basis of interventions. One hundred and two patients at one general hospital in Gyeongnam responded to a questionnaire developed on the basis of care needs perceived by nurses caring for hospitalized patients with cancer. The questionnaire was a Likert type 5 point scale with 56 items on five need categories ; 1) informational 2) physical care : 3) emotional care 4) socioeconomic care and 5) special care needs. Internal consistency of this questionnaire was Cronbach's $\alpha$＝.9101 for total items. The data was collected from March 1st to May 31th, 1998, by two graduate nurses. In the data analysis, mean & standard deviation were calculated to identify the degree of care need of each item, and the t-test & ANOVA were done to determine the effects of patients' demographic background on their care needs. The findings are summarized as follows ; 1) The mean score of total of need items was 3.048. Of the four need categories the highest score was informational at 3.4, followed by emotional care, 3.063, physical care, 2.623, and socioeconomic care, 2.599. 2) In the informational need category there were four subcategories with 19 items. Medication and pain control had the highest score, 3.755 ; second was diet and exercise, 3.613 ; third was disease and treatment process, 3.337 ; and last was personal hygiene and infection prevention at 2.687. 3) In the physical care need category there was nine items, IV infusion for nutrition and management of treatment complication was above 3.2 points and the remaining items were in the 2.847-2.070 score ranges. 4) In the emotional care need category there were seven items. The highest need was in support for relationships with health personnel, 3.673. The need for support of religions beliefs and support for having a religion were low at about 2 points. 5) In the socioeconomic care need category there were six items. Support for medical insurance expansion and financial support were above 3 points. Legal support and support for caring of children were low in the care needs. 6) In the special care need category the there were 15 items. Informational need about immunization and informational need about effects of disease on growth and development were high, above 4.1 points. Need for decubitus care and prevention, sitz bath and incontinence care were low, below 2 points. 7) There were significant differences in degree of care need according to admission rate, education level, marital status, religion and caregiver's religion. In conclusion, homecare needs perceived by hospitalized patient's with cancer was moderate, but informational need was higher than direct care need, leading to the conclusion that the provision of sufficient information to patients with cancer at discharge is needed. Nursing interventions should be developed considering the patient's background.

A amphipod, Leptocheirus plumulosus was exposed to Ag contaminated sediments to evaluate relative importance of various uptake routes (sediment, porewater, supplementary food) for Ag bioaccumulation in sediment-dwelling marine invertebrates. Additionally, influence of AVS (acid-volatile sulfide) on the partitioning of Ag to porewater and on the Ag bioavailability was determined to evaluate the utility of AVS criteria for the management of metal contaminated sediment. The experimental sediments were spiked with 4 levels of Ag (0.1-3.3 ${\mu}$mol Ag/g) and AVS concentrations were manipulated to 40 or <0.5 ${\mu}$mol/g, then equilibrated for >2 months to allow pore water/particulate distributions similar to nature. A L. plumulosus was incubated in the contaminated sediments with overlying water for 35d. During the exposure, the amphipods was fed with supplementary food ($TetraMin^{(R)}$) with or without Ag contamination. Following exposure, tissue Ag in L. plumulosus was strongly correlated with the weak acid extractable Ag in sediments ($r^{2}$=0.87, p<0.001). The ratio of AVS to Ag-SEM (Ag extracted simulaneouls with AVS) had a strong influence on porewater Ag concentration, consistent with previous studies. However, Ag bioaccumulation in L. plumulosus was not influenced by AVS concentrations. The amphipods fed Ag contaminated food took up ${\sim}$ 1.8 X Ag accumulated by the amphipods fed uncontaminated supplementary diet. The result suggests that the benthic invertebrates exposed to metal contaminated sediments would accumulate metals largely via ingestion of contaminated sediments and food, with minor contribution from dissolved sources of porewater and overlying water.

Background/aim : Gallbladder stone is the most common disease of biliary tract. It is lead to acute abdominal pain. The cholecystitis which is caused by in gallbladder stone occurs frequently and the possibility of the gallbladder cancer comes to be high. Our study was designed to determine the prevalence and risk factors gallbladder stone in a population who community. Materials and Methods : We enrolled a total of 826 (male : 297, female : 529) persons who 60 or older in Jeju-do 10 places from 2008 July one months. The height, weight, liver function tests, lipid profile, fasting blood sugar, were all measurement. They had their gallbladder examined with using ultrasonography. Statistical significance was defined as a p-value less than 0.05. Results : Among 826 persons, gallbladder stone was found in 49 persons (5.9%). The male is 6.1% and the female is 5.8%, the male 1.03 times appeared more highly the female. The body mass index above of 23.0 kg/$m^2$ with the gallbladder stone was 69.3% (p<0.047). Conclusion : The gallbladder stone appeared highly according to age increases. The obesity is the risk factor of gallbladder stone. The weight management and diet control is a possibility of reducing a gallbladder stone creation.

We investigated the effects feeding illite on growth performance and meat quality characteristics in finishing pigs. Forty-eight pigs ($Landrace{\times}Yorkshire{\times}Duroc$; $68.3{\pm}1.6 kg$ average initial body weight) were used in a 50 day experiment. Pigs were randomly placed into one of four experimented diet groups (0, 0.2, 0.5 and 1% illite) and were slaughtered at approximately 110 kg live weight. Although there were no significantly differences in daily weight gain, feed intake and feed conversion between controls and groups fed illite, those values were increased as increasing of illite concentration in feed. Carcass weight, carcass ratio and backfat thickness were not affected by dietary illite supplementation. However, the percentage of A grade carcasses were significantly increased by dietary supplement of 1.0% illite. There were no significantly differences in moisture, crude protein and crude ash between controls and groups fed illite, but the crude fat of 1.0% illite supplemented groups was significantly lower than other groups (p<0.05). All muscles from control and treatment groups had normal pH 5.55-5.68. However, lightness ($L^*$) values of pork decreased as increasing illite supplement. Whereas red-ness ($a^*$) and yellowness ($b^*$) values were not significantly changed. In fatty acid composition, palmitoleic acid and linoleic acid were significantly higher in 1.0% illite dietary group, saturated fatty acid was decreased and unsaturated fatty acid was increased by 0.5-1.0% illite supplementation.
