Purpose: This study aimed to identify the influence of social pressure related to appearance and body image dissatisfaction on mental health in adolescents. Methods: Participants included 293 high school students. The data were collected from March 4 to 29, 2019, and were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression with SPSS ver. 21. Results: Mental health was positively correlated with social pressure related to appearance and body image dissatisfaction. Factors influencing mental health were peer pressure (β=.28, p<.001) and parental pressure (β=.22, p<.001) related to appearance; body image dissatisfaction (β =.11, p=.034); "high" (β=-.18, p=.004) and "moderate" (β=-.22, p<.001) perceived school achievement; and "satisfied" response to school satisfaction (β=-.27, p=.028). These factors explained 32% of the variance in mental health. Conclusion: These results imply the need to develop effective intervention programs that enhance body image satisfaction to prevent poor mental health in adolescents.

The purpose of this study was to investigate the changes of obesity and depression level of obese children on body weight control program. The body weight control program included nutrition education, psychotherapy and exercise for weekly session during 9 months. The results from this study were as follows. A total of 27 obese children participated in this study. The average age of children was 11.7 years, 70% of children had regular exercise. Average exercise time was 1.2 hours and watching television time was 1.8 hours. Children's serum composition were within normal ranges. Rohrer index(RI) was significantly decreased to 163 from 167(p<0.001) and BMI was significantly decreased to 23.9 from 24.5(p<0.01) after body weight control program. There was not significant difference in depression score after body weight control program and there was not significant correlation between obesity and depression level. The response tendency of depression items indicated obese children had negative depression feelings and couldn't have hopeful mind to the future. But there were significant increase(p<0.05) in depression and hopeful mind in factor analysis. The suggestion and limitations of this study were discussed. These results suggest that body weight control program including nutrition education, exercise and psychotherapy may be effective for helping obese children.

In this study, the leveling control system for a tractor has been developed. The experimental model showed that the implementation of the proposed hydraulic control system fur the prototype design of a slope land tractor was feasible. The front axle was designed as a center pin type and the rear axle was designed as a trailing arm type. The leveling control of the body on the slope land was accomplished by controlling the height of the right and left trailing arms using the electronic controlled hydraulic cylinder. The maximum leveling control angles were ${\pm}$15$^{\circ}$ for roll angle and 7$^{\circ}$far pitch angle. The front and rear wheel drives were transmitted by gears from the main shaft to the final drive. The adaptability of the hydraulic control system was tested and investigated by analyzing the system response in time and frequency domain. The hydraulic control system on a step input showed a linearly increasing trend without any overshoot state. The hydraulic control system on a frequency input showed a little phase differences and gain drops within the range of 0.3Hz.

Purified diets containing five graded levels of lysine were fed to a total of 125 growing chicks (25 chicks per treatment) to evaluate lysine requirements for growth and maintenance. A model was developed to separate lysine requirement for maintenance from requirement for growth. Based on weight gain response, the daily lysine requirement for growth was 12.06 mg/g gain and the daily lysine requirement for maintenance was 0.332 times metabolic body size ($W^{0.75}$). Similarly, the lysine requirement for growth was 0.457 mg/mg nitrogen gain and the daily lysine requirement for maintenance was 0.344 times metabolic body size. The plateau of plasma lysine concentration was reached at 354.75 mg intake/day. The total lysine requirement was 414.27 mg/day or 1.0% of the diet, 420.11 mg/day or 1.01% of the diet based on weight gain response and N gain response, respectively. Previous lysine requirements for growing chicks of 1-28 days old were in close agreement with these estimates. As a percentage of protein, lysine requirement was calculated to be 7.3% and the reported lysine content of chick muscle crude protein of 7.46% was closely related.

We examined the effect of individual sweating responses on thermoregulatory responses induced by heat of sorption, immediately after the onset of sweating. The present study consists of two experiments. In experiment 1, made of 100% cotton (C) and 100% polyester (P) clothing were exposed in the chamber at ambient temperature (Ta) of $27.2^{\circ}C$ and relative humidity (rh) raised from 50% to 95% at five different increase rates of environmental vapor pressure (VP). The increase rate of clothing surface temperature (Tcs), peak Tcs and peak time showed significant correlation with the increase rate of environmental VP in C-clothing (p<0.05). In experiment 2, seven female subjects were studied during leg water immersion ($35-41^{\circ}C$) for 70min in Ta of 27.2 and 50%rh. There were significant positive correlations in the increase rate of clothing microclimate VP vs. changes in Tcs, skin blood flow, mean skin temperature and mean body temperature (p<0.05). The present results showed that individual clothing microclimate VP had significant effects on thermoregulatory responses induced by heat of sorption wearing C ensembles.

The administraction of ginseng butanol fraction(GBF) inhibited the development of tolerance to and physical dependence on morphine induced by morphine multiple injections in mice. Each group of mice was injected with morphine hydrochloride (40mg/kg s.c.) three times at 8 hr intervals for a period of 6 days. GBF (25, 50, 100, 200mg/kg) was injected (i.p.) to mice 1hr prior to the third morphine injection daily. Inhibition of morphine tolerance by GBF was evidenced by the increase in analgesic response to morphine hydrochloride (10mg/kg) as estimated by the tail flick method and the reduction in morphine dependence was estimated by the decreased number of the naloxone induced withdrawal jumping mice. Further evidenced that GBF reduced the development of morphine dependence was indicated by the fact that GBF decreased the loss in body weight.

Objective : We investigated the sasang constitutional difference of physiological and psychological response in various thermal environmental conditions. Methods: Among 210 volunteers, 30 healthy subjects were selected through the QSCC II (a questionnaire for constitutional discrimination) and the manual examination of a specialist in sasang constitution. Subjects consisted of 10 each Soyang(少陽), Soeum(少陰), and Taeum(太陽). Experimental environments were set by six different conditions to be $23^{\circ}C,\;50\%\;RH,\;0.lm/s;\;25^{\circ}C,\;25\%\;RH,\;0.lm/s;\;25^{\circ}C,\;50\%\;RH,\;0.lm/s;\;25^{\circ}C,\;50\%\;RH,\;0.4m/s;\;25^{\circ}C,\;75\%\;RH,\;0.1m/s;\;and\;27^{\circ}C,\;50\%\;RH,\;0.1m\s$ (respectively temperature, relative humidity, and wind velocity). Skin temperature, core temperature, heart rate variability (HRV), and galvanic skin response (GSR) were measured for each subject Additionally, subjects were asked about comfort through the questionnaire. Results: From the viewpoint of external temperature sensibility, in all experimental environments, generally the Taeum type feels hotter and the Soeum feels colder than other types. In relative comfort, Soeum types were most sensitive to wind velocity change. From the viewpoint of body temperature, Taeum type was lower and Soyang was higher than other types. The measurements of HRV and GSR showed no difference between the types. Conclusion : The four sasang constitution types showed different responses to various thermal environmental conditions. Accordingly, our research could provide basic data for building the optimal thermal conditions for individuals based on sasang constitution. Consequently, it will help to build a healthy environment for everyday life.

This study investigated the integrated effects of family, school, internet, and mass culture factors on the identity formation of adolescents. Specifically, the purposes of this study were to categorize adolescents into groups by what they do during the time except the life in school and to investigate differences among the groups regarding the identity information(body image, self-esteem, self-identity) and the influences of environmental factors on identity formation of adolescent. The study distributed questionnaires to middle and high school adolescents of five representative cities in South Korea. The total respondents were 2240(960 from Seoul/Kyongki, and 320 each from Taegu, Pusan, Kwangju, and Taejon). The response rate was 98.7%. The data were analyzed by factor analysis, cluster analysis, ANOVA, Duncan test, and multiple regression. The results showed that Korean adolescents were segmented into five groups : TV preference group, computer preference group, friends and family involvement group, homework and study preference group, and study institute involvement group). The five groups were significantly different in regard to body image pursuit, self-esteem, and self-identity. The body image pursuit, self-esteem, and self-identity of adolescents were significantly different in regard to each environmental factors, in each adolescent group.
