Background: Prolonged sitting at work can lead to adverse health outcomes. The health risk of office workers is an increasing concern for the society and industry, with prolonged sitting work becoming more prevalent. Objective: This study aimed to explore the variation in muscle activities during prolonged sitting work and found out when and how to take a break to mitigate the risk of muscle symptoms. Methods: A preliminary survey was conducted to find out the prevalence of muscle discomfort in sedentary work. Firstly, a 2-h sedentary computer work was designed based on the preliminary study to investigate the variation in muscle activities. Twenty-four participants took part in the electromyography (EMG) measurement study. The EMG variations in the trapezius muscle and latissimus dorsi were investigated. Then the intervention time was determined based on the EMG measurement study. Secondly, 48 participants were divided into six groups to compare the effectiveness of every break type (passive break, active break of changing their posture, and stand and stretch their body with 5 or 10 mins). Finally, data consisting of EMG amplitudes and spectra and subjective assessment of discomfort were analyzed. Results: In the EMG experiment, results from the joint analysis of the spectral and amplitude method showed muscle fatigue after about 40 mins of sedentary work. In the intervention experiment, the results showed that standing and stretching for 5 mins was the most effective break type, and this type of break could keep the muscles' state at a recovery level for about 30-45 mins. Conclusions: This study offers the possibility of being applied to office workers and provides preliminary data support and theoretical exploration for a follow-up early muscle fatigue detection system.

These days the use of personal computer has become generalized at factory, office, house, etc and this fact indicates that visual display terminal work became popular in every field of our society. The use of computer improves work efficiency, productivity & qualify but in addition, it also generated the physical and mental diseases or defects so called VDT syndrome to workers. The purpose of this paper is to analyse the computer-work-related anti-physical, anti-psychogenic symptoms & side effects through the data drawn from workers who use computers on their works, and to find out methods of improvement & humanization of computer works. The follows are the results of questions about personal sensibility of VDT syndrome. 1. Female workers are more sensitive to the side effects of computer labor than males. 2. Workers aged twenties feel more severe symptoms of VDT syndrome than thirties or fourties, but there are no level of significance. 3. Middle managements workers are the most sensitive group to VDT syndrome, on the other hand tow managements are less sensitive than operators. 4. The result of questions indicates that a phone conductress show more severe VDT syndrome symptoms than business affairs or an engineer workers, with level of significance. 5. The longer computer work engagement period, the more evident VDT syndrome symptoms appear. For instance, workers who have more than 2 year engagement period complain more severe symptoms, compared workers who have less than 2 year engagement period. 6. Long computer working time per day also increases VDT syndrome severity specially people who have more than 2 hours in working time in a day have much less severe symptoms, compared people whose daily working time exceeds 2 hours. 7. Specific body part which shows VDT syndrome symptoms is shoulder, wrist, neck, finger, eye, waist, arm in the order of severity. 8. Sensibility of VDT syndrome symptoms have effect on degree of vocational satisfaction.

질병발생 양상이 변화되고 건강에 대한 관심이 증가하며, 건강에 대한 임상적이며 객관적인 평가와 동시에 환자의 주관적 인식을 포괄하는 건강 상태를 평가하기 위한 노력이 계속되고 있다. HRQoL을 측정하는 것을 이러한 노력 중 하나로 꼽을 수 있는데, 본 연구는 일반적인 HRQoL과 구강건강 상태와의 관련성을 알아보기 위해 수행되었다. 대표성 있는 국민건강영양조사 자료 중 제6기 2차년도(2014년) 자료를 활용하여 분석을 수행하였다. EQ-5D로 측정된 일반적인 HRQoL에 영향을 미치는 요인은 성별, 연령, 교육수준, 소득수준, 민간건강보험 가입 여부, 주관적으로 인식하는 전신건강상태, 최근 1년간 치통 경험, 현존 치아 수로 확인되었다(p<0.05). 구강건강은 전반적인 건강상태를 결정짓는데 중요한 역할을 하기 때문에 객관적인 구강건강 상태가 전신건강에 영향을 미치고, 이는 결국 일반적인 HRQoL에 관련성이 있는 것으로 볼 수 있다.

OP-Art was not appreciated by painters and art critics. and according1y has been forgotten in art history. But recently Op-Art is revitalized in fashion and is in its palmy days. This study intends to re-assess the value of Op-Art, by reviewing its influence on fashion design in the post-modern society To this purpose, conceptual characteristics of Op-Art was analyzed. And then, on the bases of these characteristics, the figural characteristics and the meaning of Op-Art in fashion design of post-modern society was re-explained. Op-Art is characterized as an art of flatness of picture plane which uses repetition of simple forms and colors. It is also based on trick of visual perception. Finally. it creates an impression which is flickering or vibrating by means of optical illusion. These characteristics give birth to some features such as simplicity. anonymity and mobility in the Op-Art fashion. The meanings of Op-Art in fashion design in post-modern society are as follows. First, repetition of simple units employed in Op-Art produces feeling of simplicity. which makes the Op-Art fashion works perceived as polysemy. In other words, the feeling of simplicity can be interpreted In diverse perspectives within the social context of our society. The material civilization and technology civilization, which causes the alienation and standardization of man. can be the backgrounds of the Op-Art fashion. Second, Op-Art is an art based on perspectives of spectators. Anonymity in the Op-Art fashion enhances participation of spectators. which gives Op-Art a sense of affinity. Third, through the feeling of mobility created by optical illusion techniques. the Op-Art fashion expresses the opposition to the ideal body image made by power group. In post-modern society, Op-Art in fashion gives new meaning to art. Op-Art in fashion proposes new roles of artist and spectators, and new concepts of art related with roles of human beings. Through general sensibility of men, Op-art in fashion can express new recognition of the post-modern society.

Geometrical figures have been used as artwork motifs from the ancient times to the present day. The area of fashion, being a part of modern art, is also largely influenced by geometry and geometrical shapes are being used as a motif for fashion design now more than ever before. However, studies about geometry in the fashion field are not yet done enough and further research is necessary. This research will therefore investigate the usages of round, square and triangular design in contemporary fashion. The main scope of this research is to look at the type of expression and analyze the intrinsic meanings of these shapes in modern fashion. This research will look profoundly into the general characteristics of these geometrical figures and analyze the effects and uniqueness found in the world collection introduced since 2007. As a result from this study, it was found that round and square objects were perceived in such a straightforward and positive way and these designs, when worn, really completed the final look. On the other hand, the triangular design was used mainly for spatial expansion and was interpreted in a more metaphorical, indirect and abstract way. The intrinsic meaning of round, square and triangle figures in contemporary fashion consists of the informal features that really steps out of the formative clothing structure. The topological changes that is formed from the interactive functions and the wholism that creates a new system through integration of the human body and clothing contains the intrinsic meaning of these geometrical figures. Based on the research results, the method of expression and the characteristics of modern day fashion's geometrical figures was able to be easily understood. This work provides the useful information on the development of fashion design and the extended interpretation of clothing structure.

In this study, the diffusion phenomenon of casual Hanbok which started in the mid 1990s and has been widely spread ever since with innovative features in design, materials, etc., was reviewed. Through the interviews of 45 People who have worn casual Hanbok the advantages and disadvantages of casual Hanbok related to its innovative characteristics were recorded and analyzed. Through the questionnaires distributed to 482 adults living in Seoul, Busan, and Darjeon, the factors related to the adoption of casual Hanbok were examined. The following are the results from the empirical study. First the adoption of contemporary casual Hanbok is due to the consumers′ positive response to the excellence of casual Hanbok′s various innovative characteristics. What the consumers perceived as innovative characteristics of casual Hanbok in the survey results validated the findings of the depth interview, identifying seven subcategories of the innovative characteristics of casual Hanbok; aesthetics, positive training effect on body and mind, difficulty in we, practicality, psychological attachment for "Our Clothes", economic efficiency, and symbolic compatibility. And consumers who think highly of such spiritual and identity values as national consciousness, nature affiliation, and community consciousness, had high evaluation to casual Hanbok However, consumers′ prejudice against Hanbok that Hanbok is for old people, uncomfortable, and not suitable to modern life, tuned out to have a negative influence on the adoption. From these results, it can be concluded that casual Hanbok of the late 1990s is a fashion with innovative characteristics, different from the one in the l980s worn by the demonstrators of popular movements and democratic movements, and it emerged as a new symbol with the characteristics of cultural movement like community consciousness and nature affiliation.

Objectives : This study was conducted to examine the factors implicated when people start smoking again after a 6 month cessation, and was carried out at the smoking cessation clinic of a public health center. Methods : The study subjects were 191 males who had attended the smoking cessation clinic of a public health center for 6 months in an attempt to quit smoking. Data was collected, by phone interview, regarding individual smoking habits, if any, over the 6 month study period. The factors which may have caused an individual to smoke again were examined. This study employed a health belief model as it theoretical basis. Results : Following a 6 month cessation, 24.1% of the study group began to smoke again during the 6 month test period. In a simple analysis, the factors related to individuals relapsing and smoking again included barriers of stress reduction, body weight gain and induction of smoking by surroundings among perceived barriers factor of our health belief model(p<0.05). In multiple logistic regression analysis for relapsed smoking, significant factors included barriers of stress reduction and induction of smoking by surroundings(p<0.05). The most important reason of for an individual to relapse into smoking was stress(60.9%) and the most likely place for a relapse to occur was a drinking establishment(39.1%). Conclusions : Our results indicate that both regular consultations and a follow-up management program are important considerations in a public health center program geared towards maintaining smoking cessation.

Impact and process evaluations were performed in order to verify the effectiveness of a public health nutrition program developed for child-bearing aged women in Korea. Participants included 58 high school girls who were divided into two groups. Each group received four 50 - 60 minute nutrition education lectures regarding healthy eating, osteoporosis, constipation and nutrition labeling in every two weeks. Each session took 50- 60 minutes. Regarding nutrition knowledge, there was a significant increase of degree of perception (p = 0.0004) , but no change in degree of accuracy after implementation (p = 0.9522) . Nutrition education was also effective in attitude change, showing more participants were ready to change their eating behaviors in terms of meal regularity (p = 0.0455) and less processed food intake (p =0.0143) . After implementing nutrition education, effective behavioral changes were observed in milk consumption (p =0.0037) and meal regularity (p = 0.0882) as well as daily activity such as stair use (p = 0.0701) . However, nutrition education had no effect on body mass index and perceived health status. In process evaluation conducted by a 9 item questionnaire, grand mean score was $4.17 \pm$0.72 out of 5. Proportion of items with scores higher than 4 ranged $68-91\%$. These results suggest that the nutrition education program used in this study was effective and useful. For a wider use of this program, more research was recommend for a strategy development of program diffuse. (Korean J Nutrition 38(10): 873$\sim$879,2005)
