The function of the school uniform is to represent the role of a student and also to restrict the scope of action for the student. Many students wear school uniforms for the most of their daily life. So the school uniform is very important for students during the school days. The purpose of this study was to suggest the fundamental information for the development of the school uniform design based on actual wearing conditions and preferred designs. Photos of school uniforms of 61 girls' high schools in Seoul were analyzed. Surveys of actual wearing conditions and preferred designs were investigated. The major conclusions of the study were as the following: 1. Most of the high school girls wore the uniform jackets that had tailored collars, were single breasted, slightly fitted, and that have a medium length between the waistline and hipline. Many students wore skirts with various pleats and knee length. Many school uniforms were navy blue and grey. 2. Many students bought ready-to-wear school uniforms from agencies with their parents. When they bought the school uniforms, they tried it on and confirmed the sizes on their own. However, since they didn't know the size systems, and they had to repair the size and design of the school uniforms. Students felt uncomfortable with how the shoulders and sleeves fit. 3. Uniform Jackets with tailored collars, single breasted, slightly fitted, and a short waistline length were preferred. Pleats skirts with knee length or upper-knee length were preferred. Navy blue and grey colors, and elastic fabrics were preferred. 4. When comparing the actual wearing conditions and preferred designs of school uniforms, there were a few differences in styles, but overall, students preferred shorter lengths of jackets and skirts. It is considered to reflect the fashion trends and the students' pursuit for beauty.

This study examines the risk of overheating of a school building, under extreme hot weather conditions, in 14 locations in the United Kingdom using the overheating criteria defined in Building Bulletin 101 (BB101). The building was modelled as naturally ventilated, mechanically ventilated and in mixed mode and was simulated both for the current and the projected weather conditions of the 2050s. Under the current weather conditions, results of the simulations show that when naturally ventilated, the school building fulfils the BB101 criteria only in the areas of Edinburgh and Glasgow. In the simulations of the building as mechanically ventilated and in mixed mode, mechanical cooling was provided in order for the building to comply with the overheating criteria. A comparison of the required cooling loads between the two scenarios shows that application of mixed mode ventilation results in less cooling loads.

The purpose of this study was to compare understanding of school foodservice management and environmentally friendly agricultural products between urban and rural elementary school children's mothers. Subjects were 400 elementary school parentsliving in Jeonnam. The results are summarized as follows. School foodservice program helped to solve unbalanced diets, develop minds and bodies, and improve eating habits. Mothers showed a higher degree of satisfaction for school foodservice containing environmentally friendly agricultural products. The primary reason for favoring environmentally friendly agricultural products was improvement of health and securing safe foods. The most important parameter of school foodservice management was sanitary control of food materials>sanitary control of foods>sanitary conditions of place for meals>sanitary conditions of cooker>sanitary conditions of tableware. In conclusion, school foodservice should be financially responsible to make policies effective.

The study is focused on making space of the abolished primary school for college dormitory in rural area which has regional type nearby city. We, firstly, analysed regional conditions and then surveyed various data for space conditions of dormitory. By surveying exterior space and interior renovation, and analysing the actual conditions of dormitory, we propose design factors and model of using facilities of the abolished primary school. So, the purpose of it is to suggest making space and a model of dormitory utilization of abolished school in regional type nearby city. It is a spacial case of re-using facilities of abolished school in rural area, but we expect that abolished school make an offer another type of using facilities.

The purpose of this study was to investigate the actual wearing conditions and the preferences of knit wear school uniforms. The subjects were 480 high school girls from 6 high schools placed in Daejeon. The method of study is a survey consisted of actual wearing conditions questionnaires, preferences questionnaires, and demographic attribution. Data was analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS 12.0 program. The results of study are as follows. First, high school girls over 90% wearing knit wear school uniforms were satisfied with current knit wear school uniforms(navy color, V-neck, and wool mixed). Second, high school girls preferred 100% cotton material and black/white/gray color group. The style of knit wear school uniforms was most preferred monochrome cardigan with cable pattern. High school girls wanted to show neat image by knit wear school uniforms and to diversify the style of them. Third, the differences of preferences between groups, they were wearing knit wear school uniforms(A group) or not(B group), were about pattern and improvement. A group preferred school mark pattern, and wanted to improve the quality and after service. B group preferred monochrome cable pattern, and wanted to diversify the style. Both groups wanted to wear knit wear school uniforms because knit wear was 'warm' and 'comfort'. Consequently, knit wear school uniforms will help high school girls express individuality and beauty.

Objectives: To analyze the association between changes in perceived physical and psychosocial working conditions and change of sickness absence days in younger and older (< 50 and ${\geq}50$ years) food industry employees. Methods: This was a follow up study of 679 employees, who completed working conditions survey questionnaires in 2005 and 2009 and for whom the requisite sickness absence data were available for the years 2004 and 2008. Results: Sickness absence increased and working conditions improved during follow-up. However, the change of increased sickness absence days were associated with the change of increased poor working postures and the change of deteriorated team spirit and reactivity (especially among < 50 years). No other changes in working conditions were associated with the changes in sickness absence. Conclusion: Sickness absence is affected by many factors other than working conditions. Nevertheless, according to this study improving team spirit and reactivity and preventing poor working postures are important in decreasing sickness absence.

With global aging, the number of patients with heart failure has increased markedly. Heart failure is a complex condition intricately associated with aging, organ damage, frailty, and cognitive decline, resulting in a poor prognosis. The relationship among frailty, sarcopenia, cachexia, malnutrition, and heart failure has recently received considerable attention. Although these conditions are distinct, they often exhibit a remarkably close relationship. Overlapping diagnostic criteria have been observed in the recently proposed guidelines and position statements, suggesting that several of these conditions may coexist in patients with heart failure. Therefore, a comprehensive understanding of these conditions is essential, and interventions must not only target these conditions individually, but also provide comprehensive management strategies. This review article provides an overview of the epidemiology, diagnostic methods, overlap, and prognosis of frailty, sarcopenia, cachexia, and malnutrition in patients with heart failure, incorporating insights from the FRAGILEHF study data. Additionally, based on existing literature, this article discusses the impact of these conditions on the effectiveness of guideline-directed medical therapy for patients with heart failure. While recognizing these conditions early and promptly implementing interventions may be advantageous, further data, particularly from well-powered, large-scale, randomized controlled trials, are necessary to refine personalized treatment strategies for patients with heart failure.

The fairly recent standard of equipping mobile devices with advanced imaging sensors has opened the possibility of conveniently diagnosing skin conditions, anywhere, anytime. For this application, we attempted to estimate skin conditions from a skin image taken by a mobile handheld camera. To estimate the skin conditions, we specifically identified three skin features (pigmentation, pores, and roughness) that can be measured quantitatively from a skin image. The experimental data indicate that the existing thresholding methods are inappropriate for extracting the pigmentation and pore skin features. Thus, we propose a new line-fitting based thresholding method for skin feature detection. We thoroughly evaluated our proposed skin condition estimation method using our skin image database. The experimental results show that our proposed thresholding method can better determine the threshold leading to the most visually plausible detection, when compared to existing methods. We also confirmed that skin conditions can be feasibly estimated using a common mobile handheld camera (for example, a smartphone).

Frequency regulation in off-normal conditions has been an important problem in electric power system design/operation and is becoming much more significant today due to the increasing size, changing structure and complexity of interconnected power systems. Increasing economic pressures for power system efficiency and reliability have led to a requirement for maintaining power system frequency closer to nominal value. This paper presents a decentralized frequency control framework using a modified low-order frequency response model containing a proportional-integral(PI) controller. The proposed framework is suitable for near-normal and emergency operating conditions. An $H_{\infty}$ control technique is applied to achieve optimal PI parameters, and an analytic approach is used to analyse the system frequency response for wide area operating conditions. Time-domain simulations with a multi-area power system example show that the simulated results agree with those predicted analytically.

Unlike other ready-made suits, which are normalized based on aspects like, designs, materials, sewing methods, has to be worn for three years, designing and pattern development of school uniform depends greatly on satisfaction and appearance. Furthermore, school uniform is of importance as many teenagers spend most of their time at school. In the present work, an attempt has been made to suggest ideal school uniform for female middle school students based on their actual uniform conditions and design preferences, so that the demands of artistic aspect, and the requirements of a suitable uniform for a female teenager can be fulfilled. Initially, a survey about the actual wearing condition was held to figure out the actual uniform conditions and design preferences. Based on the result of the survey, two types of school uniform were made with different patterns. Finally, the most ideal school uniform for female middle school students was suggested based on the experiment involving a few aspects such as suitability and functionality. It is conjectured that school uniform survey and investigation, could provide useful information to the school uniform business market.
