High density polyethylene (HDPE) pipe has many advantages over metallic pipe, and has been used in non-safety related application for years in some nuclear power plants (NPPs). Recently, HDPE pipe was introduced into safety related applications. The main difference between safety-related and non-safety-related pipes in NPPs is the design method of extra loadings such as gravity, temperature, and earthquake. In this paper, the mechanical behavior of HDPE pipe under various loads in pipe gallery was studied by finite element analysis (FEA). Stress concentrations were found at the fusion regions on inner surface of mitered elbows of HDPE pipe system. The effects of various factors were analyzed, and the influence of various loads on the damage of HDPE pipe system were evaluated. The results of this paper provide a reference for the design of nuclear safety-related Class 3 HDPE pipe. In addition, as the HDPE pipes analyzed in this paper were suspended in pipe gallery, it can also serve as a supplementary reference for current ASME standard on Class 3 HDPE pipe, which only covers the application for buried pipe application.

This study was performed to investigate the dietary supplement use and related factors by college students attending in web class. One thousand four hundred college students(male: 632, female: 768) were participated in this study. The questionnaire about dietary supplements use, demographic characteristics, eating behavior, health-related lifestyles, nutrient intake was self-administered and the data were obtained via internet or mail. Dietary supplements were taken by 63.6%(male : 62.2%, female : 64.2%) of subjects. The higher concern about nutrition and health, the higher the incidence of dietary supplements taking was(p < 0.05). Dietary supplement users were satisfied more than non-users about meal served(p < 0.05). Supplements used by most male students were lactic acid beverage, Chinese medicine, geigogi geisoju and multivitamin, Chinese medicine, fiber-processed flood for female students. Most of dietary supplement users answered that the sources of information on supplements were 'friend, family or relatives' and 'TV or radio'. Dietary supplement users were taking significantly more nutrients compared to non-use. Therefore, it may be necessary to provide nutrition information and education which show that balanced diet is the best nutritional strategy for health promotion and diet supplements can be helpful in deficient state nutrients.

This research was intended to furnish basic data which can be helpful to maintain and improve the skin health and to activate aromatherapy by analyzing the knowledge, attitude and behavior on the aromatherapy skin care of college students. As their grade got higher, students of beauty class showed the level of knowledge on aromatherapy higher than those of non-beauty class, and that of girl students was higher than that of boy students and as the living standard of students got higher, and pocket money of a month of them got more, the level of knowledge on aromatherapy of them was high, and as the interest in appearance and satisfaction on appearance of them got higher, the level of knowledge on aromatherapy of them was high. In common characteristics, as the living standard of them got higher, and pocket money of a month of them got more, the level of attitude on aromatherapy of them was high. As the interest in appearance of them got higher, the level of attitude on aromatherapy on the interest in appearance of them was high. In the characteristics related with the skin, as the skin health condition of students got healthier, the level of attitude on aromatherapy of them was high, and it was high in the students who had much agony on the skin color.

This paper presents the results of a series of experiments conducted to model a magnetorheological damper operated in shear mode. The prototype MR damper consists of two parallel steel plates; a paddle covered with an MR fluid coated foam is placed between the plates. The force is generated when the paddle is in motion and the MR fluid is reached by the magnetic field of the coil in one end of the device. Two approaches were considered in this experiment: a parametric approach based on the Bingham, Bouc-Wen and Hyperbolic Tangent models and a non parametric approach based on a Neural Network model. The accuracy to reproduce the MR damper behavior is compared as well as some aspects related to performance are discussed.

The Korean GDP per capita doubled during the last 10 years. As the GDP increases, Korean health behaviors such as, eating, drinking, smoking, and exercise habits changed as well. Compared to the remarkably advanced diagnostic technologies and therapeutics during the last decade, the leading causes of death in Korea scarcely changed. Among the leading causes of death, cerebrovascular disease, heart disease, diabetes, liver disease and hypertension are closely related to health behaviors. Using the database of medical check-up between 2001 and 2010, the authors performed a longitudinal study for the prevalence rates and the trends of major chronic adult diseases among the 2,721 workers along with their health behavior. Among the diagnostic test items, fasting blood sugar, cholesterol and BMI levels showed steady increase and these three test items all showed linear trends (p<0.001). The average blood sugar and cholesterol levels were near worrying levels. Moreover, the average BMI of males was found to be at the overweight level, intimating the possibility reaching thee Obese Class I level soon if there are no aggressive counter measures. Fasting blood sugar and cholesterol levels were higher in a drinking group as compared to a non-drinking group, and the BMI levels were also higher in the drinking group and the smoking group as compared to the non-drinking and the non-smoking group (p<0.001). Finally, the authors believe that the fasting blood sugar, cholesterol and BMI levels should be designated as target monitoring test items in the medical check-up for Korean employees.

본 연구는 중학생을 대상으로 지속적인 음악청취가 발표불안에 미치는 영향을 밝히고자 하였다. 실험 참여자는 여중생 두 개 반을 대상으로 통제집단 33명, 실험집단 33명씩 총 66명이고, 음악처치를 받는 집단과 아무런 처치가 주어지지 않는 집단으로 나누었다. 처치 전, 처치 1주 후 및 2주 후에 자기보고식으로 이루어진 발표불안척도(SAS)와 교사의 평가로 이루어진 발표행동 평가척도(SBES)를 통하여 발표불안을 측정하였다. 결과는 음악처치를 받은 실험집단에서 발표불안이 의미 있게 감소하는 것으로 나타났다. 따라서 음악에 의한 감성 유발이 발표상황에서 받는 스트레스에 긍정적인 효과가 있었다.

Purpose: The aim of this study was to evaluate the influence of the mothers' native country on influenza vaccinations in adolescents in multicultural families. Methods: Data were gathered from the 13th (2017) Youth Risk Behavior Web-Based Survey. Logistic regression analyses were conducted using a complex sample data analysis method. The participants in this study had a father who was born in Korea and a mother born outside of Korea. The sample included 481 adolescents. Results: The analysis of non-adjusted confounding variables showed that influenza vaccination was higher in multicultural adolescents whose mother's native country had an annual minimum temperature less than $21^{\circ}C$ (odds ratio [OR]: 1.81, 95% confidence interval [CI]: 1.20~2.74). Furthermore, when the analysis was adjusted for confounding variables, an annual minimum temperature less than $21^{\circ}C$ in the mother's native country had a statistically significant association with influenza vaccination (OR: 2.12, 95% CI: 1.36~3.29). Conclusion: Multicultural adolescents belong to a socioeconomically vulnerable class, and their health promotion behaviors are influenced by their mothers' culture. Thus, healthcare providers and school nurses should provide adolescents with appropriate information related to influenza vaccination depending on their mothers' culture and their family's cultural background.
