Background: The study investigated the causes of safety accidents by facility, focused on safety accidents caused directly or indirectly by school facilities at elementary schools in S City. Purpose: The objective of this study is to provide materials for planning the construction of school buildings and the installation of school facilities and for improving existing facilities and ultimately to minimize mental and Physical losses from safety accidents caused by school facilities and to create pleasant education environment. Method: We selected 10 elementary schools in S City, analyzed the factors of safety accidents caused by facilities inside and outside the schools, and presented the results of the analysis including the factors of safety accidents caused by elementary school facilities. Result: It was found that safety accidents caused by elementary school facilities can be prevented to some degree by considering safety accidents in facility planning. As the safety accident rate is higher at elementary schools than at middle and high schools, it is essential to consider safety accidents in planning the construction of an elementary school and to execute safety accident prevention education in order to reduce safety accidents at elementary schools. In addition, as the curriculums are revised and new facilities are introduced for the new curriculums, elementary students' physical, psychological and environmental factors should be analyzed and studied closely and the results should be reflected in establishing the standards for the installation of elementary school facilities.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

The stability of protein tissues and protein fibers in the human muscle is investigated in the presented paper. The protein fibers are modeled via tube structures embedded in others proteins fibers like the elastic substrate. Physical sport and physical exercise play an important role in the stability of synthesis and strength of the protein tissues. In physical exercise, the temperature of the body increases, and this temperature change impacts the stability of the protein tissues, which is the aim of the current study. The mathematical simulation of the protein tissues is done based on the mechanical sciences, and the protein fibers are modeled via wire structures according to the high-order theory beams. The thermal stress due to the conditions of the sport is applied to the nanoscale protein fibers, then the stability regarding the frequency analysis is investigated. Finally, the impact of temperature change, physical exercise, and small-scale parameters on the stability of the protein tissues are examined in detail.

The purpose of this study was to analyze the differences in the expenses of private education and the economic preparations for old age according to household income and consumption wants for education in mothers with school-aged children. The data used in this study were collected from 416 mothers with school-aged children aged 8 to 19 years old living in Daegu. The data analysis methods adopted for the study were two-way ANOVA and Scheff$\acute{e}$ test. The results of this study were as follows: First, there were differences in the private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of low household income, the mothers with high consumption wants for education spent more money on academic education and music, fine arts or physical education than the mother's with low consumption wants for education. On the other hand, in the group of mothers of high household income, the mothers with low consumption wants for education spent more money on academic education and spent less money on music, fine arts or physical education than the mothers with high consumption wants for education. There were no meaningful differences in the group of mothers of middle household income. Second, there were differences in the perceived burden of private education expenditure according to the household income and the consumption wants for education in mothers with school-aged children. In the group of mothers of middle household income, the mothers with low consumption wants for education perceived there was a higher burden for private education expenditure than the mothers with high consumption wants for education. Third, there were differences in the expenditure preparation for old age and the economic preparation behavior for old age according to the level of household income. The mothers with high household income spent more money on preparation for old age and did well in economic preparation behavior for old age than the mothers with middle and low household income.

BACKGROUND/OBJECTIVES: One ongoing effort to curtail dyslipidemia in school children is through lifestyle intervention. This study analyzes outcomes of the intervention of nutrition education and Javanese traditional game-based physical activity, on lipid profiles of overweight and obese children. SUBJECTS/METHODS: The experimental study consisted of three steps: data collection (October to December 2016), intervention processes (January to March 2017), and final report preparation (April to May 2017). This was a split-plot block study, enrolling a total of 72 subjects. Traditional game intervention (12 meetings) and nutrition education (9 meetings) was carried out within 3 months with material related to obesity. RESULTS: Our results showed no decrease in the levels of total cholesterol in the group receiving nutrition education (rise by 1.56 mg/dL), but when compared to subjects without intervention, total cholesterol levels experienced was increased. The group which did not receive physical activity showed increase in the total cholesterol, whereas the traditional game intervention group showed a decrease of 0.05 mg/dL total cholesterol at the end of the intervention. Nutrition education and physical activity interventions did not influence any reduction in the low-density lipoprotein cholesterol (LDL-C) levels, but rather showed a tendency to increase at the end of the intervention. However, the increase in LDL-c levels in the traditional game group was lower than in other intervention groups. Duncan's test indicated that the effect of nutrition education and physical activity interventions did not differ from the cut-off values of LDL-C and high-density lipoprotein cholesterol. CONCLUSIONS: Total cholesterol and triglyceride levels in the traditional game group tended to decrease at the end of the intervention, but the results did not differ much from other intervention groups. We deduce that nutrition education and traditional game-based physical activity interventions are not capable of improving blood lipid profiles in overweight and obese children within 3 months. It is necessary to increase the time of physical activity intervention to maintain the lipid profile in another study.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through $\chi^2$-test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teachers. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC than those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

The purpose of this study is to investigate secondary school teacher's perceptions and needs of computer and information literacy(CIL) convergence education and to suggest implications for promoting CIL convergence education in the actual school fields. We conducted a survey on teachers perceptions and the needs for CIL convergence education and analysed 227 secondary school teachers responses. As a result, we found that the perception of the necessity of CIL convergence education was very high while understanding level of the CIL convergence education and the actual frequency of teaching experiences were relatively low. In addition, CIL convergence education activities are mainly conducted through Informatics curriculum rather than various subjects. We identified that the main constrains of CIL convergence education were the burden on the progress of subject based curriculum as well as the lacking of teaching and learning equipments including computers. We identified that the needs for empowering teachers professional developments and constructing the physical and institutional environments of school sites were high. In discussion, we suggested the support strategies in terms of teacher professional development, institutional supports, and physical environments.

Neutron conversion detectors that use ¹⁰B-enriched boron carbide are feasible alternatives to ³He-based detectors. We prepared boron carbide films at micron-scale thickness using direct-current magnetron sputtering. The structural characteristics of natural B₄C films, including density, roughness, crystallization, and purity, were analyzed using grazing incidence X-ray reflectivity, X-ray diffraction, X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and scanning electron microscopy. A beam profile test was conducted to verify the practicality of the ¹⁰B-enriched B₄C neutron conversion layer. A clear profile indicated the high quality of the neutron conversion of the boron carbide layer.
