Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

The purpose of this study is to investigate the effect of Ondol on the bedclimate, microclimate and physiological responses of occupants. Four healthy female subjects slept for seven hours in thermal environment of detached house and apartment respectively. Their bedclimate, microclimate, skin temperature, weight loss of body, weight of bedcloth and sleepwear, body movement and subjective sensation were measureed for this study. The results were as follows; The differences of bedclimate, microclimate, skin temperature were significant according to season and residence styles. The occupants of the detached house showed higher temperature and humidity inside quilt and clothes than those of the apartment did on apartment environment. The occupants of the detached house showed higher weight losses of body, heavier weights of quilt than those of the apartment did on apartment environment in the spring, autumn and winter, lower weight losses of mattress in the autumn and winter. The occupants of the detached house moved more than those of the apartment on apartment environment when sleeping. The occupants of the detached house felt higher thermal sensation and lower humidity sensation than those of the apartment did. The occupants of the detached house felt more comfortable than those of the apartment on detached house environment, while the occupants of the apartment felt more comfortable than those of the detached house on apartment environment. The thermal environments of the apartment and the detached house had an effect on the bedclimates, microclimates of occupants and therefore the physiological responses such as skin temperature, rectal temperature, weight loss of body, perspiration and subjective sensation are different during sleeping according to their residential styles on the same environment.

A modified grey clustering method is presented to systematically evaluate the risk of water inrush in karst tunnels. Based on the center triangle whitenization weight function and upper and lower limit measure whitenization weight function, the modified grey evaluation model doesn't have the crossing properties of grey cluster and meets the standard well. By adsorbing and integrating the previous research results, seven influence factors are selected as evaluation indexes. A couple of evaluation indexes are modified and quantitatively graded according to four risk grades through expert evaluation method. The weights of evaluation indexes are rationally distributed by the comprehensive assignment method. It is integrated by the subjective factors and the objective factors. Subjective weight is given based on analytical hierarchy process, and objective weight obtained from simple dependent function. The modified grey evaluation model is validated by Jigongling Tunnel. Finally, the water inrush risk of Shangjiawan Tunnel is evaluated by using the established model, and the evaluation result obtained from the proposed method is agrees well with practical situation. This risk assessment methodology provides a powerful tool with which planners and engineers can systematically assess the risk of water inrush in karst tunnels.

Purpose: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. Methods: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). Results: At the school level, the average school body mass index (BMI, $kg/m^2$) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI ($kg/m^2$), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. Conclusion: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

The actual clothing conditions were surveyed to diagnose clothing condition of collegians in the view point of adaptation to the thermal environment in fall. Then, clothing climate, physiological responses, and subjective sensation were investigated through wearing trials on human subjects in climatic chamber based on the results from the survey. Factors to evaluate validity of clothing condition were clothing weight, clothing climate, physiological responses of human body, and subjective sensation. Adaptability of this research to thermal environment was compared to the results of Toda's and Duno's of Japan, Chung's results of Korea rural area, and Winslow's clo value. The standard values for wearing trials were values at comfortable zone, such as $32{\pm}1^{\circ}C$ of temperature and $50{\pm}10%$ of humidity inside clothing, $36.5{\sim}37.3^{\circ}C$ of ear temperature and $32.2{\sim}34.3^{\circ}C$ of mean skin temperature. Clothing weight per body surface area was 680.9 $g/m^2$ in male and 526.7 $g/m^2$ in women. Cold resistance ability of collegians was superior to Japanese and American, and similar to rural male in Korea. According to the examination of clothing adaptability with clothing weight from the investigation on physiological responses and the actual clothing conditions survey, following were found. Temperature inside clothing ($29.8{\sim}32.3^{\circ}C$) was normal, and humidity inside clothing (32.2~54.8%) was at comfortable zone. Mean skin temperature was at its comfortable zone. Therefore, 615 $g/m^2$ in male and 525 $g/m^2$ in female were a desirable wearing condition.

The purpose of this study is to weigh the students' backpacks of middle school in daily use and to analyse their physiological responses and subjective senses when carrying backpack in order to promote healthy and comfort school life of girl middle school students. Two female students were subjects who answered the questionnaires on two types of backpack and their metabolism, perspiration and the changes of skin temperature were measured in constant environment chamber, $25{\pm}1$ and $49{\pm}10$% RH. They walked on the treadmill carrying the backpack with the increment of backpack weight, 2 kg, 4 kg to 6 kg. When the backpack increases to 6 kg, the discomfort parameters and responses increases rapidly. Comparing with general type, improved type of backpack showed good results in physiological responses, but not in subjective senses, such as the ease of movement, pain, or total preference, specially in 2 kg and 4 kg. The girl students prefer the general type of backpack which is of fashion and small, when it weighs light such as 2 kg or 4 kg, while they prefer the improved bag which is functional when it is heavy as 6 kg. The longer wearing time of the medium weight, for example, 4 kg without feeling or recognition of any discomfort due to fashion style, might cause the students' posture and health weaker or more vulnerable to the problems.
