The purpose of this study was to analyze the signification system between color and clothes systematically in black and white clothes. For this purpose, after examining the images of black and white clothes, we selected 55 clothes that represented as black and white and analyzed their meanings and the sources using semiotic framework, based on the work of Saussure and Barthes. The results as follows: First, the meaning in black and white clothes was generated from original color image. White clothes of religious person like Virgin Mary, Angel expressed pure and sacred color image. And black clothes like funeral dress expressed grief and death. Next, the meaning of black and white clothes was regenerated into modern color image by new environment. After industrial revolution, black was considered as a traditional men's fashion color. With diverse leisure activities, white sports wear appeared as active and clean image. Finally the source of the meaning of the clothes was the designer or the wearer. A little black dress by Chanel who was interested in simplicity and function represents an ideal of simple and sexy object. The situation is complicated by the fact that these three kinds of explanation may be found singly or mixed together.

Stress at work and in the family is a very common issue in our society that generates many health-related problems. During recent years, numerous studies have sought to define the term stress, raising many contradictions that various authors have studied. Other authors have attempted to establish some criteria, in subjective and not very quantitative ways, in an attempt to reduce and even to eliminate stressors and their effects at work and in the family context. The purpose of this study was to quantify so-called cushioning variables, such as control, social support, home/work life conciliation, and even sports and leisure activities, with the purpose of, as much as possible, reducing the negative effects of stress, which seriously affects the health of workers. The study employs data from the Fifth European Working Conditions Survey, in which nearly 44,000 interviewees from 34 countries in the European Union participated. We constructed a probabilistic model based on a Bayesian network, using variables from both the workplace and the family, the aforementioned cushioning variables, as well as the variable stress. If action is taken on the above variables, then the probabilities of suffering high levels of stress may be reduced. Such action may improve the quality of life of people at work and in the family.

The purpose of this study was to investigate the effect of health care on the body composition and metabolic Syndrome risk factors in male office workers. The subjects of this study were 30~40's male office workers and their physical activities were increased by mobile healthcare. The date analysis in this study was carried out paired t­test using SPSS 20.0 version(${\alpha}=.05$). The result of study were as follow: First. body composition kg(p<.015), BMI(p<.041), WC(p<.026) were significantly decreased after Increase in Physical Activity Using Mobile Health Care, although these did not reach statistical significance, SMM(p<.123), BF(p<.059) was slightly increased and decreased trend. Second, SBP(p<.300), DBP(p<.384) was slightly decreased trend and BS(p<.034) were significantly decreased after Increase in Physical Activity Using Mobile Health Care, Third, plasma TC(p<.015), TG(p<.003), LDL-C)(p<.000) were significantly decreased after Increase in Physical Activity Using Mobile Health Care and plasma HDL-C (p<.003) were significantly increased. These results suggest that increased physical activity using mobile health care has a positive effect on the body composition and metabolic syndrome index in male office workers. Sedentary lifestyles could be changed by Continuous feedback using mobile healthcare.

Because of comfortable texture and easy treatment, more and more knit products has been required for leisure such as sports, traveling, hobbies, and various social activities. Therefore, the demand of knit is gradually increasing in the clothing industry. There are, however, several issues, which require solutions, and we must develop higher value-added products, which differentiate from those of developing countries allowing us to compete and win in the world market. The patterns on porcelain of underglaze iron, which had been popular from late-l5th century to mid-16th century, are diverse, unique, and traditional--so valuable patterns of our own. The computer hitting machine enables the designer to conceive new designs and produce samples of fabrics within a few minutes, which allows us to save time for mass production. Therefore, it is an essential tool for the knitting industry. After collecting, analyzing, and choosing various patterns on porcelains of underglaze iron, This study reflects the actual experience of hitting the fabrics with the patterns through the computer knitting machine which is also used to produce patterns after designing the new patterns through Adobe Illustrator and Photoshop, which has several merits. This article compares and analyzes them for production, which uses the patterns that has been designed from the patterns on porcelains of underglaze iron.

Bromotopsentin (BSM) is a bisindole alkaloid compound, which is recognized as a metabolite of the marine sponge Spongosorites sp. In this study, the antioxidant activity of BSM was investigated. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, the trolox equivalent antioxidant capacity (TEAC) assay, the superoxide radical scavenging (NBT) assay, the lipid peroxidation and hydroxyl radical-induced DNA damage assays were carried out to evaluate the antioxidant activity of BSM. It was found that BSM had stronger scavenging activity on the stable free radical DPPH and superoxide radical than L-ascorbic acid with an $IC_{50}$ value of 62 and 64 ${\mu}M$, respectively. The TEAC value which indicated the total antioxidant capacity of BSM was about 0.8, which was also stronger than L-ascorbic acid. About 1.3 ${\mu}M$ of BSM induced 50% inhibition of lipid peroxidation. 60 nM of BSM exhibited a significant protective activity against DNA strand scission by hydroxyl radical on pBR322 DNA. Taken together, we suggest that BSM possesses strong antioxidant activity, and could be a valuable new addition to the list of anti-aging chemotherapeutic agents.

In the past, waves, which are the main external forces acting on marine and coastal structures, have been dealt with only in terms of safety. Recently, various studies have been conducted to define the characteristics of waves in a specific area in order to respond to the increasing demand for diversified marine activities such as ocean energy development and marine leisure sports. Although the characteristics of waves are specific to the site, the available spectrum model proposed in previous studies are limited. In this study, we analyzed the shape of the ocean wave spectrum by comparing it with the standard spectrum model.

This study tends to grasp the physical activity on its influences and effect s to the mental health of middle school students and we tried to look for a specific plan that will help to improve middle school students' mental health. We analyzed 36,530 students in middle school using a basic data "9th (2013) health behavior of juvenile on the online". The study is analyzed by complex sample data analysis method. The degree of euphoria recognition showed the low feeling of happiness when students exercise directly below two times rather than three times a week in the Physical Education class at school. On the other hand, the possibility of stress perception degree and suicide attempt is lowered. If the number of sports team participating is below one team, euphoria would be lowered and the limit of stress perception is high. However, the participation of one or two teams make the possibility of suicide lessens rather than students taking part in more 4 teams. In order to help middle school students reduce their stress and improve their happiness, they need to participate in sports as a regular team and join intramural games more than three times a week. In this case of the lower grade, it is considered that it is necessary for them to combine the educational program for the emotional support to control their extreme behavior.
