The study purpose was to examine weight control status and related factors among 370 high school girls in Seoul. Factors examined included interest toward weight control, body satisfaction, body image, beliefs regarding weight control and self-efficacy. $65.1\%$ had attempted to control weight and were categorized into attempt group. Those in the attempt group had higher body weight (p < 0.001) and BMI (p < 0.001) than the counterparts. They tried to control weight 2.9 times on average (22.4 days each time). The major information sources for weight control were internet ($62.8\%$), and TV/radio ($17.1\%$). Exercise was most commonly used for weight control, followed by reducing meal amount and skipping dinner. The attempt group was less satisfied with body size (p < 0.001) and perceived their body size as heavier than the counterparts (p < 0.001), but they showed more interest toward weight control (p < 0.001). The ideal body size of society or the body size that they want was very thin in both groups. Twelve out of 20 beliefs regarding weight control were significantly different between the two groups. The attempt group believed more strongly on the advantages such as increased self-confidence, appearance, attractiveness (p < 0.001) and 'good for making friends' (p < 0.01) In contrast, the attempt group believed less strongly about the disadvantages including harmful effects on health (p < 0.001), parents' dislike, feelings of discouragement (p < 0.01) and becoming (p < 0.05). The attempt group showed lower overall self-efficacy to control overeating (p < 0.05) than the counterparts. Especially, the attempt group felt less control of overeating in situations such as eating-out, after school, when they are with family (p < 0.01) or with friends, when they feel hungry, during examination periods and when others offer food (p < 0.05). This study suggested that weight management education for adolescents include strategies for changing body image and beliefs regarding weight control, as well as increasing self-efficacy to control overeating.

This study was undertaken to grasp health-promoting behavior of the elderly and to identify variables related to them in order to facilitate nursing intervention for health promotion of this population. The subjects for this study were 291 old persons obtained by cluster sampling from twenty general social welfare centers located in Tague. Data were collected by self-reported questionnaires from August 13 to September 13, 1996. Questionnaires were developed based on Sherer and others' Self-Efficacy scale, Rosenberg's Self-Esteem scale, Wallston and other's Multidimensional Health Locus of Control scale, Northern illinois University's Helath Self Rating Scale, Walker and others' Health Promotion Lifestyles Profile. Analysis of the data was done by use of descriptive statistics, stepwise multiple regression, Pearson Correlation Coefficient, MANOVA, t-test, and ANOVA. The results were summarized as follows : 1. For the practice of health-promoting behavior, the mean score was 2.89 and range was 3.59 to 2.09. The factor of the highest mean score was regular diet(M=3.42) and factor of the lowest mean score as stress management(M=2.27). 2. The combination of self-efficacy, internal health locus of control, family number, and average monthly pocket money explained 30.0% of the variance of health-promoting behavior. 3. With regard to the relationship between health-promoting behavior and cognitive perceptual factor, self-efficacy correlated positively with health-promoting behavior(r=.4951, P=.0001), self-esteem correlated positively(r=.3263, P=.0001), internal health locus of control correlated positively(r=.3244, P=.0001), perceived health status correlated positively(r=.1355, P=.0274). 4. According to age(F=2.50, P=.0431), sex(t=2.14, P=.0332), marital status(F=7.85, P=.0005), education(F=5.44, P=.0003), family number(F=11.18, P=.0001), people living together(F=7.21, P=.0009), previous occupation(F=5.83, P=.0001), average monthly pocket money(F=7.27, P=.0001), there were differences of health-promoting behavior. The above findings show that health-promoting behavior are related to demographic characteristics, four cognitive perceptual factors(self-efficacy, self-esteem, internal health locus of control, perceived health status). On the basis of the above findings the following recommendations are made ; 1. Nursing interventions enhancing exercise or activity, accountability for health, stress management of the elderly must be provided. 2. Nursing strategies enhancing self-efficacy which is most significant effect on health-promoting behavior must be developed.

Sludge transporting pipes in wastewater treatment plant are easy to be clogged with struvite when the digested sludge and dehydrated filtrate are transported through the pipes, which lowers the efficiency of sludge treatment system in a WWTP. pH is one of the most important factors in struvite formation, and carbon dioxide separated from biogas can be used to control pH and struvite formation. By controlling pH, the amount of dehydrating agent can be reduced by about 10%, which saves the budget for facility maintenance. As $CO_2$ is reused and dehydrating chemicals are saved, the approach can contribute to global warming gas reduction.

A 35-day trial was carried out to determine the influence of dietary cinnamon powder (CNP) on the sensory evaluation and quality of chicken meat, carcass characteristics, plasma lipid level and growth performance of broiler chickens. There were 5 treatment groups: control; CNP 2.0%; CNP 3.0%; CNP 4.0%; and CNP 5.0%. The body weight of the broilers fed the diets containing 3.0% CNP was higher than the broilers fed the control feeds (p<0.05). The concentration of triacylglyceride, HDL-C was higher in the plasma from broiler chickens fed diets with CNP (p<0.05) but the concentrations of total cholesterol and LDL-C were significantly lower (p<0.05) compared to the control group. The carcass percentage, chicken breast and thigh weight were not different between the CNP and control groups. The WHC was significantly higher in the chickens fed 4% CNP diet, while the TBARS was significantly lower (p<0.05) in the chickens fed 3% CNP diet compared to the control group. The color of the breast muscle from the chickens fed 3% CNP diet was lighter than those from the control groups (p<0.05). The sensory evaluation of the taste and savor related to CNP in fried or boiled chicken meat were significantly better from the broiler chicken fed diets containing CNP than the control group (p<0.05). These results suggest that dietary cinnamon powder may improve savor and quality of chicken meat in broiler chickens.

The purpose of this study was to investigate the factors influencing health perception in the elderly, to provide the basic data for health behavior program and nursing intervention. The subjects of this study were 240 elderly person over the age 60, living in Seoul and Kangnung. They were conveniently sampled for this study and the data was collected from June 1999 to September 1999. The instruments for this study were the Health Perception Questionaire developed by Ware(1979), the OARS Functional Assessment Questionaire (Duke University 1978), and Multidimensional Health Locus of Control by Wallston, Wallston, and De Vills(1978). The data were analyzed by using SPSS Win computer Program. The results are as follows; 1. The total mean score of the health perception was 52.02(S.D=${\pm}$7.07) in a range of 33 to 69, and the mean score of the functional status was 27.02 (SD=${\pm}$2.75) in a range of zero to 28 and the mean score of the health locus of control was 65.66(S.D=${\pm}$8.68) in a range of 43 to 90. And The mean scores on the HLOC subscales were HLOC-I: 23.73${\pm}$4.56 (range: 6-30), HLOC-P: 23.07${\pm}$4.74 (range: 6-30), HLOC-C: 18.55${\pm}$4.03 (range: 11-30). 2. There was a significant positive correlation between health perception and functional status(r=.216, p=.001), and health perception and the health locus of control(HLOC) were not correlated at the level of statistical significance. However, the HLOC-I and health perception were correlated positively(r=.328, p=.000), and the HLOC-P were correlated negatively (r=-.129, p=.046). 3. There was a significant difference statistically in the degree of health perception according to the age(F=3.351, p=.002), spouse(t=2.232, p=.021), education level(F=7.373, p=.001), disease(t=3.639, p=.000), group activity (t=2.458, p=.015). drink(t=2.327, p=.021). 4. Stepwise multiple regression analysis revealed that the most powerful predictor of health perception was internal health locus of control. A combination of HOLC-I, functional status, HLOC-P, group activity explained 17.9% of the variance for health perception in the elderly. In conclusion, the results of this study show that internal health locus of control factor is very important in explaining the health perception for the elderly. Therefore, it will be considered internal health locus of control factor in nursing intervention and program in order to enforce the health behavior for elderly people .

This study was carried out to investigate the influence of dietary germanium supplementation on the meat quality of duck. Ducks raised for 42 days were slaughtered and the ground meats were stored at 3$^{\circ}C$ for 12 days under 1200 lux. Experimental treatments were divided into 3 kinds of meat from ducks fed germanium as follows; 1) Control(natural water + commercial feed), 2) T1(1～10 days: natural water + commercial feed, 11-42 days: natural water + commercial feed supplemented with 1 % germanium), 3) T2(1～10 days: germanium submersion water + commercial feed, 11～42 days: natural water + commercial feed supplemented with 1 % germanium). The pH of duck meat was not different among the treatments(p>0.05). The germanium treatments exhibited significantly higher crude fat content in both breast and thigh meat(p<0.05). In the fatty acid composition, T2 contained more unsaturated fatty acid than control or Tl. TPA(textural profile analysis) value such as hardness, gumminess, chewiness and adhesiveness decreased in meat from duck fed supplemental germanium. Cholesterol contents of duck meat decreased in dietary supplemental germanium treatment compared to control, but were not significantly different among them(p>0.05). Dietary germanium supplementation affected on lipid oxidation of meat during storage. TBARS of meat from duck fed germanium was lower than that of control(po.05). The CIE L*, b* and h$\^$0/ values of germanium treatments were significantly(p.o5) higher than those of control. Also a* value showed more stable in germanium diet treatment during storage. Therefore, dietary supplemental germanium to duck resulted in light brownish color formation, improvement tenderness and retardation of lipid oxidation of meat during refrigerated storage.

The purpose of this study was to investigate the effect of ketoconazole (20 mg/kg) on the pharmacokinetic parameters and the bioavailability of paclitaxel (40 mg/kg) orally coadministered in rats. The plasma concentration of paclitaxel in combination with ketoconazole was significantly (p<0.05) increased from 8 hr to 24 hr compared to that of control. Area under the plasma concentration-time curve (AUC) of paclitaxel with ketoconazole was significantly (coadministration p<0.05, pretreatment p<0.0l) higher than that of control. Peak concentration $(C_{max})$ of paclitaxel pretreated with ketoconazole were significantly (p<0.05) increased compared to that of control. Time to peak concentation $(T_{max})$ of paclitaxel pretreated with ketoconazole were significantly (p<0.05) shorter than that of control. Half-life at elimination phase $(t_{1/2{\beta}})$ of paclitaxel pretreated with ketoconazole was significantly (p<0.05) prolonged compared to that of control. Based on these results, it might be due to both inhibition of the enzyme cytochrome P450 and p-glycoprotein, which engaged in paclitaxel absorption and metabolism in liver and gastrointestinal mucosa.
