To find the association of perception of health status with lifestyle of different ethnic groups living in north-eastern part of China, a cross-sectional questionnaire survey was done by 10 local health workers for 375 Korean immigrants and 217 Chinese whose age was 30 years old or more. Because Korean immigrants showed higher mortality than Chinese, we expected to find significant lifestyle related with perception of health status which was known to be a predictor of mortality by different ethnic groups. The results were as follows : 1. We found that 59.7% of Yanbian Koreans and 42.9% of Yanbian Chinese felt unhealthy (p=0.000). 2. For Yanbian Koreans, significant variables associated with perception of health status were selected through logistic regression analysis and they were sex; female to male with an OR=2.45 (95% confidence interval[CI] 1.06, 5.64), prevalence of chronic illness with an OR=5.48 (95% CI: 4.62, 15.56), mont of meal; small or moderate to full with an OR=2.67 (95% CI : 1.40, 5.09), preference of spicy food with an OR=1.78 (95% CI : 1.04, 3.04), and less amount intake of vitamin $B_2$, with an OR=2.29 (95% CI : 1.33, 3.93). 3. For Yanbian Chinese, significant variables associated with perception of health status were prevalence of chronic illness with an OR=4.97 (95% CI : 2.11, 11.68), history of taking ginseng with an OR=3.72 (95% CI : 1.33, 10.43), and less intake of vitamin C with an OR=0.18 (95% CI : 0.07, 0.46). In conclusion, sex, presence of chronic illness, dietary habit, and amount of $vitamin-B_1$ intake were associated with perception of health status in Yanbian Koreans. Presence of chronic illness, experience of ginseng intake, and amount of vitamin C intake were associated with perception of health status in Yanbian Chinese. To prove cause-effect relation between perception of health status and lifestyle, further study is needed for these different ethnic groups.

Many a number of policies have been tried to reduce auto accidents so far, but it is obvious that further studies are still needed to find a more fundamental and multi-dimensional preventive measure with effect. The National Mental Health Statistics shows that the most profound forms of negative emotions, that is, depression and anxiety, have been increasing, but studies on such a topic are scarce to find. Therefore, we conducted a structural analysis between the negative emotions, including depression and anxiety, of drivers and their driving behaviors using a Structural Equation Modeling(SEM) technique. The review of past literature and studies indicated that not all of human emotions manifest themselves as the ultimate behaviors because they go through emotion regulation Strategies. For this reason, the purpose of this study was set to analyze the structural model developed in this study reflecting the emotion regulation strategies. The result of our analysis showed that the driver's negative emotion had a more significant influence on dangerous driving behaviors than safe ones, and especially, the expressive suppression strategy was found to be the highest factor. Also, the total effect analysis with the negative emotional factors showed that expressive suppression had more significant influence compared to that of cognitive reappraisal. The implication of this study might provide a better understanding on driving behaviors of the drivers and could be used as a fundamental study for future policy development to reduce traffic accidents.

The purpose of this study was to compare weight control behaviour, eating habits and health-related life habits according to the obesity degree by body fat percentage (%Fat) among middle-aged women. The subjects were 170 middle-aged women who lived Gunsan City, and they were assigned to one of the following groups based on their %Fat; normal weight group (18% - < 28%), overweight group (28% - < 33%) and obesity group (over 33%). The height, body weight, %Fat, the circumference of waist and hip of them were measured. Eating habits and health-related life habits were evaluated based on questionnaires. The results were as follows. Their weight, %Fat, body mass index (BMI), relative body weight (RBW), waist, hip, and waist-hip ratio (WHR) were significantly higher in the obesity subjects when compared to the normal and overweight subjects. Self-perception for weight (p < 0.001), desire for weight control (p < 0.01), and reasons of weight control (p < 0.05) were different among three groups. The main skipped meal was breakfast (67.9%), reasons of skipping meals were different among three groups (p < 0.05), and main reasons were "lose one's appetite" and "have not enough time". Food habits score for each food was not significantly different among three groups, but eating the meal on thinking with food combination in normal group was higher than overweight and obesity group (p < 0.01). Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes. Therefore, proper nutritional education for middle-aged women in obesity group is recommended regular diet, good food habits and exercise. The middle-aged women must decrease the frequency of eating out, snack and the salty foods, and increase the fruits and vegetables. They must have healthy life styles for exercise, smoking, and drinking.

The present times is rapidly growing and changing. As both an industry and a social legislation are running after a generality, relatively the number of people who are out of it is gradually increasing. Those people are getting skeptical about their positions as well as their existences, so that a social deviant phenomenon has been continuously arising by themselves in public and private area. It is the Vandalism . People are often exposed to this Vandalism which is occurring around their life. Accordingly this study analyzed cause-and-effect Vandalism. As a means of impediment against the progressing Vandalism in design process, the study as been developed by approaching to an ergonomics design, a simple shape design (minimalism), a semantic design, a re-useful design. As a result, it comes to the fact that the Vandalism from the view of design is caused by a lack of ergonomics and user-interface, a failure of simple structure, a complication of excessive functions. Furthermore, it comes to the conclusion that industrial design is playing an important role in the contribution of social development, to create a design obstructing the vandalism will bring development of sound society.

The evolution of biotechnology is no longer strange to the hypothetical scenario of cloning human genes to make cloned human beings. The characters of are cloned humans made in the laboratory by the 100-year-old life planning. They are cohabited in a school called Hailsham, where they are secretly reared. The purpose of this project is to provide healthy organs to real human patients with incurable diseases. The main characters Cathy, Tommy, and Ruth experience the growth of body and consciousness here during adolescence, and they also know the secret of identity as a clone. As adults, they move to a second residence, Cottage and are ready to begin organ donation. The second stage is also part of a program to provide more genuine-like organs to real patients. Even though they know all the plans that humans have built, they do not resist them and fatefully accept their situation. However, their non-responsiveness is not a declaration of renunciation of life, but a self-sacrificing life extension for another future that is the extension of life through their organ donation. The film emphasizes the fraternity and sacrificial attitudes of the cloned human beings and shows that it is necessary to continue the discussions on cloned human beings from a bio-ethical point of view supported by philosophical reasons.

Recently, as living standards have improved, many people are becoming more interested in health, and self-training is increasing through exercise to prevent and manage pre-illness. In general, an imbalance of muscles causes asymmetry of posture, which can cause various diseases by accompanying an adjustment force, circulation action, displacement of internal organs, etc.. In this study, the development of fitness software that can be self - training among smart wears has attracted considerable attention in recent years. In this study, a technology was proposed for the commercialization of self - trainer fitness wear by a simulation through Android - based applications. Self - trainer fitness software was developed by combining a conductive polymer, fashion design, sewing, and electric and electronic technology to monitor the unbalance of the muscles during exercise and make smart wear that can calibrate the asymmetry by oneself. In particular, a polymer sensor was fabricated by deriving the optimal MWCNT concentration, and the electrode signal was collected by attaching the electrode to the optimal position, where the electrode signal line using the conductive fiber was designed and attached to collect the signal. A signal module that converts the bio-signals collected through electrical signal conversion and transmits them using Bluetooth communication was designed and manufactured. Self-trainer fitness software that can be commercialized was developed by combining noise cancellation with Android-based self-training application using a software algorithm method.

This study was conducted to determine the levels of job stress, as well as its association with psychosocial factors (type A behavior pattern, locus of control, and self-esteem). Self-administered questionnaires were given to 634 clerical public officers in the C Provincial Office between February 18 and Mar. 10, 2013. As a result, the job stress levels of the subjects was significantly different according to age, sex, educational level, marital status, job position, job career, satisfaction in job life, smoking, alcohol drinking, sleeping time, type A behavior pattern, locus of control, and self-esteem. Regarding the correlation of job stress and psychosocial factors, the level of job demand was negatively correlated with the internal locus of control. The decision latitude was negatively correlated with the type A behavior pattern, internal locus of control and self-esteem. Supervisor support was negatively correlated with the external locus of control. In hierarchial multiple regression analysis, the affecting factors to the job stress selected variables, such as age, subjective health status, job position, overtime work, experience of sick absence, satisfaction in work, sleeping time, leisure time, visiting out-patient department, type A behavior pattern, locus of control, and self-esteem, and the explanatory powers of these factors was 32.1%. In particular, the factors related to the psychosocial factors (type A behavior pattern, locus of control, self-esteem) were strongly related to the job stress, increasing the explanation of factors up to 15.0%.
