본 연구의 목적은 폐경기 여성의 외모관리행동이 우울과 정신건강에 미치는 영향 관계를 분 석하고 신체매력지각의 매개효과를 실증적으로 분석하는데 있다. 연구대상자는 서울·경기 소재 폐경기 여성 258명을 대상으로 구조화된 설문지를 통하여 자료를 수집하였다. 수집된 자료는 기술통계, 확인적 요인분석, 상관관계, 구조방정식 모델, bootstrapping기법을 이용한 매개효과 분석을 실시하였다. 일련의 연구절차를 통하여 도출된 결론은 다음과 같다. 첫째, 폐경기 여성의 외모관리행동은 우울과 통계적 유 의미한 부적(-) 영향을 미쳤으며, 정신건강과는 정적(+) 영향을 보였다. 둘째, 폐경기 여성의 신체매력지 각은 우울과 통계적 유의미한 부적(-) 영향을 미쳤으며, 정신건강과는 정적(+) 영향을 보였다. 셋째, 폐 경기 여성의 외모관리행동과 우울, 정신건강과의 관계에서 신체매력지각은 부분매개 효과가 있는 것으로 나타났다. 이는 폐경기 여성의 외모관리행동을 통하여 변화된 자신의 긍정적 신체매력지각이 우울과 정 신건강에 더욱 강화된 영향력을 제공할 수 있다는 것을 시사한다. 본 연구의 결과는 외모관리행동으로 폐경기 여성의 우울과 같은 부정적 정서를 극복하고 건강한 삶을 살아갈 수 있도록 중재변수로서의 타 당성을 제고하였다는 측면에 의의가 있다.

고밀도폴리에틸렌(HDPE)은 대표적인 열가소성 플라스틱으로서 재활용성, 내충격성 등이 우수하여 차세대 친환경 소형선박용 재료로 각광받고 있다. 그러나, HDPE의 열변형온도는 하절기의 선체 온도와 비슷한 수준이며, 재료의 열팽창 특성으로 인해 선박 구조용 재료로서의 적용 가능성에 대한 기술적 검토가 필요하다. 본 연구에서는 선박이 일상적으로 겪을 수 있는 상온 이상 온도범위에서 HDPE 의 기계적·열적 물성치를 도출하였고, 모의설계한 HDPE 어선을 대상으로 연중 태양복사열과 기관실 내부 온도가 가장 높은 하절기 운용 상황을 모사한 열전달 해석을 통해 구조부재들의 온도변화 및 분포, 응력 및 변위 구배 등을 확인하고자 하였다. 혹서기의 높은 기온과 강한 태양복사에 노출되는 HDPE 선체의 온도는 재료의 열변형온도 수준까지 상승하며 열팽창에 의한 변형 및 국부응력을 보여 설계 및 검토단계에서 선체 변형을 고려할 필요가 있고 향후 선체변형 대응방안 및 구조안전성 평가기준 마련 시 온도상승에 따른 물성치 변화를 고려할 필요가 있다.

Stress and fatigue are general physical aspects of our daily lives. It has been shown that physical therapists have different levels of job stress and fatigue according to the type A/B behavior patterns. This study collected data from 212 physical therapists between October 28 and November 23, 2016 using an anonymous, self-administered questionnaire. The study results showed the proportion of physical therapists with the Type A behavior patterns(TABP) was 18% greater than that of physical therapists with the Type B behavior patterns(TBBP). In this study, physical therapists with TABP were compared with physical therapists with TBBP. The results indicated that physical therapists with TABP were more inclined to experience higher levels of overall job stress and fatigue from the following stress factors: physical environment, job requirement, and job autonomy. Therefore, the stronger the tendency toward TABP, the stronger the feeling of job stress and fatigue from physical environment, job requirement, and job autonomy. Those with a tendency toward TBBP showed positive correlations between job requirement and the total job stress score; thus, the stronger the tendency toward TBBP, the stronger the feeling of overall job stress and fatigue from job requirement. This study suggests that it is necessary to manage the job stress and fatigue of physical therapists with both TABP and TBBP and to manage the job stress and fatigue of physical therapists with the type A behavioral pattern.

High pollutant-loading capacities (up to 319 times its own weight) are achieved by three-dimensional (3D) macroporous, slightly reduced graphene oxide (srGO) sorbents, which are prepared through ice-templating and consecutive thermal reduction. The reduction of the srGO is readily controlled by heating time under a mild condition (at 1 10–2 Torr and 200°C). The saturated sorption capacity of the hydrophilic srGO sorbent (thermally reduced for 1 h) could not be improved further even though the samples were reduced for 10 h to achieve the hydrophobic surface. The large meso- and macroporosity of the srGO sorbent, which is achieved by removing the residual water and the hydroxyl groups, is crucial for achieving the enhanced capacity. In particular, a systematic study on absorption parameters indicates that the open porosity of the 3D srGO sorbents significantly contributes to the physical loading of oils and organic solvents on the hydrophilic surface. Therefore, this study provides insight into the absorption behavior of highly macroporous graphene-based macrostructures and hence paves the way to development of promising next-generation sorbents for removal of oils and organic solvent pollutants.

This current research investigated whether job stress mediates the relationship between physical environment and safety behavior of members in organization. Furthermore, we hypothesized that safety climate functions as moderator between physical environment-job stress link. In order to examine the hypotheses, 870 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which cab elaborately test the significance of our hypotheses. The results showed that job stress mediated the link between physical environment and safety behavior of members. Moreover, the relationship between physical environment and job stress was moderated by safety climate. The implications and limitations of our study and suggestions for future research were discussed.

The purpose of this study was to measure the nutrition knowledge, dietary attitude, eating behavior, physical ability and locomotion of 5-year-old-children, and thereby to provide the fundamental information necessary to develop a nutritionrelated physical education program. A survey was performed on 143 5-years-old boys and 113 girls. The results were as follows. The average score in the nutrition knowledge item, was 7.22 out of a possible 10 points; in the dietary attitude item, 32.46 out of 50 points; in the eating behavior item, 26.67 out of 40 points. According to body measurement, there was a significant difference in height by gender (p＜0.05), Significant differences in muscle mass and basal metabolic rate were also observed by gender (p＜0.001). Gender also influenced the flexibility and reflexibility (p＜0.001), with significant difference in balance of the right side (p＜0.01). Although this study was limited by its cross-sectional study design, the body muscle (p＜0.05) and basal metabolic rate (p＜0.05) were observed to have a positive relation with nutritional knowledge. In addition, there was a significant positive correlation between nutritional knowledge and dietary attitude (p＜0.01). According to the results, it is necessary to develop a long-term and systematic program with the combination of nutrition and physical education to develop correct dietary habits and for the balanced growth of children.

The questionnaire survey was made to understand the users' satisfaction and attributes. The statistical analysis was applied, the frequency analysis and percentage calculation were used to find out the citizenship and perception toward the physical factors, and paired-sample T test to compare the average.

The purpose of this study was to determine the influences on physical status and study achievement by the dietary behavior of the youth in Korea. The survey was carried from June to July, 1995 by way of questionnaire to 397 students. The students' study achievement records and physical status were analyzed by the factor of dietary behavior. The results were as follows: 1 The average physical status of male students was lean, but females were standard. 76ft of mothers of the subjects were working in specialty farming. The monthly income of their family was 1000~1500 thousand Won and students' pocket money was 20~40 thousand Won per month. 2. The aspects of meal behavior included the general idea that the meal was thought to relieve hunger, and preference of taste was spiciness The most important factor of the meals for the students was taste. Their bad meal habits were quick eating and irregularity of meals. 3. There was a significant difference in the comparison of the study achieving records with the frequency of supper However, there was no one meaningful difference between study achievement records and the attendance rate to school, health status, and living conditions. However, there was a significant difference between their study records and eating with family. The students, who had the breakfast and/or supper with family, remarked better study records than other groups. 4. Also, there was a significant difference of study records with physical status. The overweight or obese students had a lower degree of study score (p〈0.1). Adolescence is considered a period of setting up dietary behavior, so it is necessary to educate good nutrition and dietary habits for students to keep in healthy physical condition and with high study achievements.

The purpose of this study was to examine the relationships of nutritional and social factors among 100 children aged 5~6 years. Forty five children (45%) were selected from families with low socioeconomic status, while 55 children (55%) were from those with high socioeconomic status. Cognitive performance of the children was measured by the Draw a man test and the degrees of hyperactivity were assessed by both children's mothers and their teachers using two different Check List (Behavior check list and Conner's rating scale). There were few associations between cognitive performance and nutritional variables. However, levels of hyperactivity were related positively to diversity of food intake and weight percentage for age, and negatively to animal and processed food preferences. These results indicate a possible role of nutrition on psychological development.

We evaluated the nutritional and socioeconomical factors of 100 children aged 5~6 years. Forty five children (45%) were selected from families with low socioeconomic status, while 55 children (55%) were from those with high socioeconomic status. Some differences of the nutritional factors (eating behavior, food preference, food frequency) were found between low and high socioeconomic groups. This survey suggest that eating behavior, food preference and food frequency may be useful in estimating nutritional factors. And the nutrition education for the children and their meal planners is necessary to improve the nutritional status of the subjects.
