This study presents a real neutral floor surface temperature in floor panel heating system(Ondol). The Ondol heating system can keep the constant temperature. However, the actual temperature when a person sits on a floor can be different from the surface temparature of a floor it self. The contents of this study are as follows : 1) measuring the spatial distributions of thermal conditions 2) the thermal sensation vote of residents is taken in order to investigate the relation between thermal condition and human thermal sensation in sedentary condition 3) estimating the neutral floor surface temperatures by measuring floor surface temperatures.

Background: Dietary fat has been inconsistently associated with the risk of breast cancer. The purpose of this study was to examine the relationship between meat and animal and plant fat intake and breast cancer risk in subgroups by total lifetime physical activity, using data from a case-control study conducted in the Region of Western Pomerania, Poland. Materials and Methods: The study included 858 women with histological confirmed breast cancer and 1,085 controls, free of any cancer diagnosis. The study was based on a self-administered questionnaire including questions about socio-demographic characteristics, current weight and height, reproductive factors, family history of breast cancer and lifestyle habits. Unconditional logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results: High animal fat intake significantly increased OR from 1.7 times (OR=1.66, 95%CI=1.07-3.59) to 2.9 times (OR=2.9, 95%CI=1.37-6.14) independent of physical activity level, comparing the third versus the lowest quartile. Women with a high intake of red meat or processed meat and low physical activity showed increased risk of breast cancer: OR=2.70, 95%CI=1.21-6.03 and 1.78, 95%CI=1.04-3.59, respectively. The plant fat dietary pattern was negatively associated with breast cancer in sedentary women (OR=0.57, 95%CI=0.32-0.99). Conclusions: These results indicated that a diet characterized by a high consumption of animal fat is associated with a higher breast cancer risk in sedentary women, while consumption of plant fat products may reduce risk in the same group.

The bathroom is a space where humans fulfil certain daily needs, but for the disabled, it can be the most difficult space to use and may even be a cause of accidents and a source of danger. Previous studies on the bathroom have mostly proposed an ideal model of bathroom, but the majority of disabled people live in small homes of about $50m^2$ in size. As their bathrooms are usually very small, and existing houses have various structural limitations, more research should be conducted on the remodeling of residential bathrooms. This study analyzed a number of remodeling items in bathrooms, all of which were listed in previous studies. Based on 17 cases of residential bathroom remodeling in the homes of disabled people residing in Incheon in 2009, this study analyzed several remodeling items required according to the subject's characteristics, such as a lifestyle, gender, and family composition; and proposed the following remodeling requirements and improvement measures for ambulatory-disabled persons and sedentary-disabled people. First, as ambulatory-disabled people have lower-limb impairments, they required bathroom remodeling designed to improve their mobility in the bathroom. These subjects desired the installation of grab bars, as well as the elimination of floor level differences, the installation of non-slip flooring, a counter-top, a sink stand, and a shower holder whose height can be adjusted. Second, sedentary-disabled people move around in a sitting or crawling position, so many of them asked to eliminate floor level differences and vertically-installed bathroom furnishings. Basically, both people with ambulatory disabilities and people with non-ambulatory impairments requested the elimination of floor level differences and the installation of non-slip flooring and grab bars for the toilet and bathtub. They also asked for the heights of sinks, faucets, mirrors, shower holders, and cabinets to be adjusted to suit their needs.

본 연구는 2013년 지역사회건강조사 통계자료를 활용하여 젊은 여성들의 체중조절행위에 영향을 미치는 요인을 파악하고자 실시되었다. 연구대상은 전국의 19~29세 13,351명이었으며, 자료분석은 ${\chi}2$-test와 다중로지스틱회귀분석을 통해 이루어졌다. 연구결과 젊은 여성들의 체중조절행위는 연령, 결혼상태, 교육수준, 가족유형, BMI, 인지된 건강수준, 주관적 체형, 고위험 음주, 주중 좌식여가활동, 아침식사결식, 수면시간, 스트레스 인지, 우울감 경험, 자살생각 등에 따라 차이가 있었다. 그리고 젊은 여성의 체중조절행위에 영향을 주는 요인은 연령, 결혼상태, 교육수준, 가족유형, BMI, 인지된 건강수준, 주관적 체형, 고위험 음주, 주중 좌식여가활동, 스트레스 인지, 우울감 경험 등이었다. 체중조절행위 접근 시 다른 건강행위들과의 상관성을 고려할 필요가 있다.

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.

본 연구는 정부 기관에서 제시하는 청소년 신체활동지침의 실천과 스마트폰으로 인한 문제경험과의 관계를 파악하고자 한다. 이를 위해 62,225명의 "2017년 청소년건강행태조사" 데이터를 활용하여 신체활동지침의 실천과 스마트폰 변인간의 관계를 분석하였으며, SPSS 23.0 프로그램을 이용하여 다중회귀분석을 실시하였다. 분석결과 "60분이상 신체활동"을 제외한 모든 신체활동이 스마트폰으로 인한 문제경험에 부(-)적 영향을 미치는 것으로 나타났다. 또한, 유산소운동, 근력운동, 스포츠클럽참여, 좌식행동 등 정부 기관에서 제시하는 신체활동지침을 실천하는 학생은 미실천학생에 비해 스마트폰 문제경험이 감소하였으며 이는 성별로 유의한 차이를 보였다. 본 결과에 따라, 스마트폰 중독예방에 있어 해당 지침을 활용한 학술적인 심층연구와 성별로 차별화된 신체활동 증진 프로그램이 가능할 것으로 기대한다.

The purposes of this study were to assess the physical activity level (PAL) and the total daily energy expenditure (TEE) as well as to evaluate the validity of prediction equation for the estimated energy requirement (EER) in normal weight and overweight or obese children and adolescents. The subjects comprised of 100 healthy Korean students aged between 7-18. The anthropometric data was collected. PAL was calculated from the physical activity diary by the 24-hour recall method, and the resting metabolic rate (RMR) was measured by an open-circuit indirect calorimetry using a ventilated hood system. Daily energy expenditure was PAL multiplied by RMR. EER was calculated by using the prediction equation published in KDRIs. There was no significant difference in the means of age and height between the 46 obese subjects and 54 nonobese subjects. The weight and BMI of the obese group (60.2 kg, $25.3kg/m^2$) were significantly higher than those of the nonobese group (42.4 kg, $18.4kg/m^2$). However, PAL was not significantly different between the two groups (nonobese 1.45, obese 1.46). TEE of the obese group (2,212 kcal/day) was significantly higher than that of the nonobese group (1,774 kcal/day). EER (individual PA) and EER (light PA) were significantly higher than TEE (p < 0,001); however, EER (sedentary PA) was not significantly different with TEE in the two groups. These results showed that the levels of physical activity were the same as the sedentary activity both in the nonobese and obese Korean students; moreover, the predictive equation for EER published in KDRI overestimated the TEE of Korean children and adolescents. Therefore, in further research, a new predictive equation for EER should be developed for Korean children and adolescents through the doubly labeled water method.
