The purpose of this study was to assess the energy expenditure and investigate the relationship between related variables in 70 female university students. Resting energy expenditure estimated by Harris-Benedict formula, WHO/NAO/FAO formula and various formulas based on body weight and body surface area were 1366.9$\pm$74.4kcal/day, 1287.8$\pm$106.6kcal/day, 1171.4$\pm$155.8kcal/day and 1342.0$\pm$97.4kcal/day. Measured resting energy expenditure by indirect calorimetry(Model : Metavine and TrueOne2400) were 1582.0$\pm$150.1kcal/day and 1268.2$\pm$152.9kcal/day, respectively. Average step number per day was 11981.2$\pm$3014.4 steps and average step number per hour was 746.1$\pm$198.0 steps/hr. Daily energy expenditure by using Harris-Benedict formula, body weight formula, body surface area formula, WHO/NAO.FAO formula and 15-min check list formula were 2374.7$\pm$249.6kcal, 2033.5$\pm$313.2kcal, 2331.2$\pm$266.0kcal, 2240.8$\pm$185.5kcal and 2195.5$\pm$398.3kcal. Meanwhile energy intake of subjects was 1714.9$\pm$551.2 kcal. Daily energy expenditure has positive correlation(r=0.262) with daily step number. And there was significant positive correlations(r=0.35-0.68) between various daily energy expenditures and muscle mass. These results suggested that increase of daily step number by using pedometer is good method to increase daily energy expenditure. In particular, increase in step number can reinforce the amounts of muscle.

The purpose of this study was to assess the physical activity level of Korean farmers to establish estimated energy requirements during the off-season. Subjects were 90 healthy males (n = 25) and females (n = 65). Body weight, height and body fat and muscles of subjects were measured. The prevalence of obesity among farmers was 56.7% according to the BMI. The farmers spent about 18 hours 7 minutes (75.5%) in sleeping and resting. The farmers spent about 19 hours 56 minutes (83.1%) out of 24 hours (one day) in "sedentary activities" and spent about 3 hours 56 minutes (16.4%) in "light activities". Physical activity level (PAL, activity coefficient) of female farmers was 1.42 which was not significantly higher than that (1.37) of male farmers. Estimated energy requirements (EER) for farmers who were different in age groups and gender were calculated. For example, the EERs for male and female farmers were 2190 kcal/day and 1712 kcal/day, respectively. The daily energy intakes of male and female farmers were 1803 kcal/day and 1610 kcal/day, respectively. The EER of male farmers was 2190 kcal/day which was significantly higher than that (1803 kcal/day) of the recommended daily energy intake of male farmers. The results of this study suggest that estimated EER of farmers should be modified according to seasonal workload and energy balance of farmers should be evaluated to prevent obesity.

The purpose of this study is to examine the prevalence of depression in Korean middle-aged adults and to identify the gender difference in factors associated with the severity of depression. The data of 2,241 individuals who participated in the Sixth Korea National Health and Nutrition Examination Survey in 2014 were used. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9), and multivariate ordinal logistic regression analysis was performed. The prevalence rate of moderate to severe depression ($PHQ-9{\geq}10$) was identified at 5.2% (men 3.3%, women 7.0%). The factors associated with the severity of depression in men were younger age, living in metropolitan, unemployed, lower body mass index, and heavily drinking. On the other hand, women were affected by having no spouse, lower income, limited physical activity, and sleeping shorter hours.

There are a few studies that reported the association of sleep duration with calorie intake and energy expenditure. Using cross-sectional data from a population-based prospective study, we evaluated the association of sleep duration with indicators of obesity including body mass index and waist circumference, calorie intake and its proportion of macronutrients, and physical activity. The study subjects were 4,226 male and female adults, who were aged 40 to 69 years and were free of diagnosed cardiovascular disease, diabetes mellitus, and dyslipidemia at baseline. Robust regression analysis was used to analyze associations. The study found that sleep duration is inversely associated with waist circumference, calorie intake, and percent of calories from fat intake and is positively associated with percent of calories from carbohydrate intake and physical activity. The inverse association between sleep duration and waist circumference was stronger among men than among women. The inverse association between sleep duration and calorie intake was stronger among women than among men and such association was also stronger among obese persons than those with a normal body mass index. The positive association between sleep duration and physical activity was strongly demonstrated regardless of sex or obesity. Physical activity is positively associated with sleep duration independent of potential confounding factors including age, sex, income, occupation, marital status, education, smoking status, waist circumference, calorie and macronutrient intake, and alcohol intake.

In the order to grasp their physical characteristics stemming from activity amount, this paper has divided elderly women into the following group ; those with high activity in the past, those with low activity in the present, those with high activity in the present and those with low activity in the present. The analyses of the body measurements and the pie chart, and the classification of back shapes by taking photographs have led to the following results. 1. The items of depth and girth among the body measurements were significant in the past and the present activity. Those with high activity in the past had smaller sizes in depth and girth than those with low activity. 2. From the pie chart, it was shown that those with high activity in the past had smaller sizes in every index as well as in girth than those with low activity in the past. Both those with low activity in the present and those with medium activity in the present had somewhat large sizes in waist girth, bust girth, hip girth and abdominal girth and in the indices of these items. 3. The classification of back shapes by taking photograpes has shown that those with high activity in the past had the less bent body type-42 percent of Type A and 6.5 percent of Type D. Among those with medium activity in the present, Type A was most outstanding and Type C and Type D were less, This fact shows that those with medium activity in the present keep the most normal body type. This proves that the medium activity of elderly women is desirable for keeping the normal body type.

This study examined artificial joint replacement surgery for early intervention and prevention of the occurrence of delirium surgery. Data of study were analysed using the sample through the EMR (Electronic Medical Record) and after surgery to provide basic data. The subjects were elderly aged 60 years or more and the number of the sample was 821. Data were analysed by using SPSS 20.0 with t-test, $x^2$-test and multiple logistic regression analysis. The study results showed patients with artificial joint replacement surgery incidence of delirium was 13.5%, findings of these variables insisted that the main influencing factors of delirium were caused by age, fall history, physical activity, emotional status, body mass index (BMI) before surgery. The study suggested that the above findings are required for early intervention, early detection and prevention of delirium.

In case of the BTL project for current educational faculties, the proper standards to analyze those said educational standards lack, so it is very difficult to conduct an exact analysis and those improper standards are problematic when proper management and maintenance costs are calculated. In case of such educational facilities, as students have to use them safely for a long time and the quantity of their activities and the status of their physical growth based on individual classes, as well as the features for use by facility and the regional characteristics are different, other standards for maintenance and management must be considered unlike an apartment house. Thus, in this study, to set up the standards considering the features of educational facilities, the maintenance and management level suitable for educational facilities is presented by comparing and analysing that required to maintain and manage an apartment house, targeting the experts specializing management of educational facilities.

The purpose of this study was to examine how Montessori-education program, one of different early-childhood education programs, was tied into the multiple intelligences of young children and how Montessori education program affected their multiple intelligences. It's basically meant to determine the efficiency of Montessori-education program. The major findings of the study were as follows: First, the Montessori-education program turned out to have a favorable effect on the development of the young children's multiple intelligences. Second, among the subfactors of multiple intelligences, the musical and bodily-kinesthetic intelligences of the preschoolers were little affected by the Montessori-education program, but that had a good impact on their logical-mathematical, spatial, linguistic, interpersonal, intrapersonal, and naturalist intelligences. The above-mentioned findings suggested that Montessori-education program was one of efficient teaching methods to step up the development of young children's multiple intelligences.
