The purpose of this study was to identify hindlimb muscle atrophy in stroke induced rat and determine the effect of endurance exercise on body weight, weight of hindlimb muscle during 7 days after stroke induction. Thirty four male Sprague-Dawley rats with 200-270g body weight were divided into four groups : control, control+exercise(Con+Ex), stroke, and exercise after stroke(St+Ex) group. The control group and Con+Ex group received sham operation and the stroke group and St+Ex group received right MCA occlusion operation by using silicon-coated probe. The Con+Ex and St+Ex groups ran on a treadmill for 20min/day at 10m/min and $10^{\circ}grade$. Daily body weight and diet intake were measured every morning for 7 days. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30minutes. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight of the control group at the 7th day increased by 18.3% significantly from the first day of experiment, that of the stroke group at the 7th day decreased by 6.7% significantly compared to the day of receiving right MCA occlusion operation. Body weight of the Con+Ex group at the 7th day increased by 10.3% significantly form the first day of experiment, that of St+Ex group at the 7th day also increased by 13.4% significantly compared to the day of receiving right MCA occlusion operation. The total amount of diet in stroke group decreased significantly compared to that of St+Ex and that of control group. In stroke group the wet weight of both sides of soleus, plantaris, and gastrocnemius muscles decreased significantly compared to that of control group. The relative weight of affected(left) plantaris and gastrocnemius muscles decreased significantly compared to that of the control group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in stroke group. The wet weight of right gastrocnemius muscles in Con+Ex group increased compared to that of control group. The relative weight of right gastrocnemius muscle increased significantly compared to that of the control group. The wet weight of St+Ex group increased significantly compared to that of the stroke group in both sides of soleus, plantaris, and gastrocnemius muscles. The relative weight of affected plantaris muscle increased significantly compared to that of the stroke group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in St+Ex group. Body weight and wet weight of soleus, plantaris, and gastrocnemius muscles in the St+Ex group did not recover to the values of control group. Based on these results, it can be suggested that endurance exercise during acute stage of stroke can reduce muscle atrophy related to denervation, inactivity and undernutrition.

This study was designed to investigate the role of weight control in the formation of underlying pathology in eating disorder or eating related problems. The subjects were 304 college athletes(Male : 187. Female: 121) and they were divided into two groups according to need for weight control(Weght control group: 110, Weght non control group: 194). The authors used self report questionnaire which was composed of epidemiologic data, food habit scale, eating attitude test, scale for locus of control for weight, scale for food preference and eating behavior. And we also used Eysenck Personality Questionnaire of Korean standardized edition for assessment of personality characteristics, Beck depression inventory, and the scale of hypochondriasis. The results were as follows: 1) Body mass index and the amount of cigarrette smoking and alcohol drinking showed significant differences by sex but not by need for weight control. 2) Eating habit of female athletes was the worst in all athletes. The score of eating attitude test of female athletes was higher than that of male athletes but there was no significant difference by need for weight control. Food preference and eating related behavior was also different by sex. 3) There were no significant differences in all subscales of Eysenck Personality Questionnaire, Beck depression inventory, and the scale of hypochondriasis between two groups which were divided by need for weight control. Neuroticism score was higher in female atheletes and psychoticism score was the highest in weight control male atheletes. 4) There was no significant difference in number of population with abnormal EAT score(to-tal score$\geq$26) between two groups which were divided by need for weight control. 5) The score of eating attitude test had positive correlation with the score of psychoticism and the tendency of depression in weight control male athletes but not in non-weight control male athletes. In non-weight control male athletes, the score of eating attitude test had positive correlation with the score of lie scale. so its correlation is different from those of weight control male athletes. But in female athletes, the score of eating attitude test had significant positive correlation with the score of psychoticism in both groups. In conclusion, these results suggest that the differences of eating traits in athletes are depend upon the sex difference, not upon the need for weight control. and that the role of weight control in eating disorder or abnormal eating attitude differs according to sex.

The study was carried out to determine if a difference in initial chick weight was still evident in market body weight(6 or 8 week body weight) of broilers. The data of a total of 800 broiler commercial chick raised at Poultry Breeding Farm, Seoul National University from Aug. 6, 1981 to Oct. 1, 1981 were analysed. The results were summarized as follows: 1. Although the initial chick weight was about the same, male chick grew more rapidly than female and sex difference was the most striking factor in growth rate of broiler in this analysis. 2. The relationship between initial chick weight and body weight after hatching was decreased to the increase of weeks of age in both sexes. Though the correlation coefficients of the 6 week and 8 week body weight to the initial chick weight were 0.15 & 0.15 in female and 0.18 & 0.17 in male, the relationship was highly significant in both sexes. 3. Regressions of 6 and 8 week body weight on the initial chick weight in both sexes indicate that, for each increase of one gram in weight of chick at hatching, the average increase in body weight was 8.33 gram ＆ 10.07 gram in female and 7.85 gram ＆ 11.28 gram in male. Results show that the initial chick weight (1 day of age) influence average body weight of commercial broiler at 6 and 8 weeks of age.

The weight estimation and calculation of FPSO topsides is first performed at the bidding stage of projects. At this time, it is difficult to estimate and calculate accurately the weight because most of items of FPSO are not apparently defined. Especially, in the case of the pipe rack module, its portion of the total weight and the range of weight variation are large due to special features of piping and electric equipment in the module. Thus, it is very important to estimate and calculate accurately its weight in the task of the weight estimation and calculation of FPSO topsides. In this study, the past data for the weight of the pipe rack module were collected and analyzed, the WBS (Work Breakdown Structure) for the pipe rack module was constructed, and primary variables and secondary variables for developing a weight estimation and calculation model were selected. That is, after analyzing the past data, the volume was selected as the primary variable and the regression analysis was performed based on the variable. Then, several secondary variables were selected and incorporated into a weight estimation and calculation model. At this time, the weight per discipline was assumed from ratios of the total weight. Finally, the weight of the pipe rack module was estimated and calculated by using the developed model. As a result, the deviation from the model was better than that (-20 % ~ 60 %) of other studies about the weight estimation and calculation of FPSO topsides. Thus, the validity and applicability of the weight estimation and calculation of the pipe rack could be checked.

With the aim of diagnostic research on health education. the health promoting behaviors related to elementary school students' weight control. life satisfaction. health state. self-efficacy. parent's interest and knowledge about weight control and school health education of weight control were investigated on the basis of the PRECEDE model. The data for this study were collected from a sample at an elementary school in Chongju for 5 days in July. 2004. In analyzing the data. t-test. one-way ANOVA. chi-square test and multiple regression analysis were done by using SPSS 10.1 The results were as follows : 1. The elementary school students' level of life satisfaction was above half of the full point. The score difference of life satisfaction was statistically significant by grade and academic achievement(F=4.646. p=.010. F=16.042. p=.000). 2. The perceived level of health state was moderate for all students. Normal weight students' level was significantly higher than obese students' (t=3.667. p=.000). 3. The perceived level of health promoting behaviors related to weight control was above the moderate. The perceived level of health promoting behaviors related to weight control in the obese students was significantly higher than that in normal weight students(t=-2.225. p=.027). The students used computer for 1.48 hours and watched TV for 2.52 hours a day. 4. The score of health promoting behavior self-efficacy in this subject was 70.61. 5. The parents' level of interest in the obese students' weight control was significantly higher than that in the normal weight students(t=-4.86. p=.000). 6. Sixty-six percent of the students learned about weight control education in school. 7. The health promoting behavior self-efficacy among the educational diagnostic variables was the most influential variable in students' health promoting behaviors related to weight control. This research diagnosed the needs of weight control education in elementary school by assessing various factors related to weight control behaviors. The research findings suggest that we can enhance the prevention of childhood obesity by strengthening the related factors such as parents' knowledge and interest, health promoting behaviors and self-efficacy related to weight control in school health education.

Acute and subacute toxicity of Artemisia asistica Nakai Aqua-acupuncture Solution (ANAS) were studied in ICR mice. In acute toxicity test, mice were injected intraperitoneally with single dose of $1{\times}$, $5{\times}$, $10{\times}$ ANAS, and toxicological responeses were observed for consecutive 14 days. Mortality, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with $1{\times}$ and $5{\times}$ ANAS were not affected during the experimental periods. With the $10{\times}$ ANAS treatment, there were dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. In subacute toxicity test, mice were injected intraperitoneally with doses of $1{\times}$, $10{\times}$ ANAS for 14 days. No difference was found between control and $1{\times}$ ANAS treated group in mortality, changes of body weight and organ weight, and serum biochemical values. However, Dead animals, changes of body weight and organ weight, and increased serum biochemical values were observed with $10{\times}$ ANAS treated groups. These results suggest that $1{\times}$ ANAS causes no toxicity in acute and subacute toxicity tests. However $10{\times}$ ANAS causes toxicity in both tests.

Purpose: This research was conducted to compare the effect of a wellness program on knowledge of obesity and weight loss in women schizophrenia inpatients. Methods: A nonequivalent control group pretest-posttest design was used for this study. A total of 44 patients with schizophrenia were randomly divided into an experimental group (22) and a control group (22) in a 12-week multimodal weight control program. For 6 weeks, the experimental group received approximately an hour of teaching on obesity interventions and for another 6 weeks one hour of teaching on exercise and weight control interventions while the control group received the usual care. The outcome variables were measured before and after the program. Data was analyzed with the ${\chi}^2$-test and t-test using PASW Statistics 18. Results: For those who completed the weight control program, there was a mean weight loss of 1.37kg by the end of the intervention. The experimental group showed significant improvement in knowledge of obesity and weight loss. Conclusion: The wellness program was effective in reducing the weight of women schizophrenia patients as well as being effective in increasing knowledge of obesity. Therefore, nurses must consistently educate women schizophrenia inpatients about health care and knowledge of obesity.

Purpose: The study investigates the degree of maternal self-esteem, postpartal depression, and family function in mothers of normal and of low birth-weight infants. Method: A retrospective cohort design was applied to compare the variables of interest between a group of 73 mothers with normal birth weight infants and a group of 45 mothers with low birth-weight infants, using the maternal self-report inventory(MSRV), Edinburgh Postnatal Depression Scale(EPDS) and Family APGAR(FAPGAR). Result: The total mean score was 82.57 for MSRV, 8.45 for EPDS, and 6.83 for FAPGAR with no differences between two groups. A positive correlation was found between MSRV and FAPGAR, while a negative correlations between MSRV and EPDS, and FAPGAR and EPDS. Regardless of the direction of the relationship, the degrees of the correlations were stronger in low birth-weight mothers group than in normal group. Conclusion: No differences in MSRV, EPDS and FAPGAR between the normal and the low birth-weight group considered as beneficial effects of the follow-up management which low birth-weight group was engaged in. This suggested the early intervention(follow-up) for the family with risk factor(low birth-weight) could reduce negative outcomes such as the impaired maternal self-esteem and family function, and the occurrence of postpartal depression, retrospectively.

Background: The consequences of falls are often debilitating, and prevention is important. In theory, the lower the center of mass (COM), the greater postural stability during standing, and a weight belt at the waist level may help to lower the COM and improve the standing balance. Objects: We examined how the limit of stability (LOS) was affected by the lowered center of mass with the weight belt. Methods: Twenty healthy individuals participated in the LOS test. After calculating each participant's COM, a weight belt was fastened ten centimeters below the COM. Trials were acquired with five weight belt conditions: 0%, 2%, 4%, 6%, and 8% of body weight. Outcome measures included reaction time, movement velocity, endpoint excursion, maximum excursion, and directional control in 4 cardinal moving directions. Results: None of our outcome variables were associated with a weight belt (p > 0.075), but all of them were associated with moving direction (p < 0.01). On average, movement velocity of the COM and maximum excursion were 31% and 18% greater, respectively, in mediolateral than anteroposterior direction (5.4°/s vs. 4.1°/s; 97.5% vs. 82.6%). Conclusion: Our results suggest that postural stability was not affected by the weight-induced lowered COM, informing the development and improvement of balance training strategies.
