  • Background: A group health service is a system that delegates workplace health management to an entrusted institution. There have been various studies on group health services to date, but recent changes, such as an increase in foreign workers, are rapidly changing industry characteristics. Methods: Satisfaction was assessed using a 27-question survey distributed among 203 workplaces employing health professionals. The survey items consisted of general characteristics, comprehensive satisfaction, requirements for health professionals' work, and satisfaction with work environment management, ergonomic management, and healthcare management. Multiple regression and frequency analyses were performed. Results: The comprehensive satisfaction was 4.08 points on average, out of 5. The comprehensive satisfaction of health professionals in the industry was positively correlated with each factor. Hazardous materials and chemical management (material safety data sheets, MSDSs) were the most common requirements. Conclusion: A low level of satisfaction with work environment management indicates high demand for healthcare management. The working environment should be improved by identifying characteristics of the workplace, examining harmful substances, inspecting equipment, and enhancing worker methods. The shorter the work experience of health professionals, the more dependent they are on group health services. The variables affecting comprehensive satisfaction were the period of work, healthcare management satisfaction, and work environment management satisfaction. Most of the requirements of health professionals in the workplace were practical improvement case presentations, MSDSs, and legal document management.

  • Nowadays people are turning to have a more intimate environment-friendly lifestyles. In the clothing industry they are focusing on making products that are more human-friendly and not harmful to the environment. In the midst of the spread of consumption research is being done to develop manufacturing textiles that do not induce pollution. For instance, advantages of the natural textile fibers, cotton, silk, and ramie, have been newly recognized in terms of environment-friendliness, Together with these fibers, the natural high molecular materials, such as chitosan and hyaluronic acid, have found new roles in the application sectors of human-friendliness and environment-friendliness. Products using these substances and processing methods can make the products more wearable, have high sensitivity, make people feel aesthetic appreciation for the products, and make them appreciate the value of a more healthier environment. In a survey according to subjects in their 20s and 30s, their preferences towards their consciousness and awareness of the development of materials as well as their attitude towards environment-friendly products were determined as a conclusion. It was shown that consumers that are more conscious about the interest of the environment as well as the problems concerning the environment were more intent on buying products that were environmentally-friendly. Women have shown more active and positive attitudes towards the importance of the awareness of the environment in comparison with men. Generally, consumers in their 20s and 30s preferred the feel of materials that were less than 1% concentration process than those of materials that were 1% concentration process. To increase the "rustly" feeling of the materials, it was found that 1% concentration process was suitable for manufacturing.

  • Effort has been performed for latest 20 years to improve resident's comfort and indoor environment in building. And interest and effort to improve indoor air environment among various indoor environment elements have continuously increased since 1990s, because it is examined scientifically that various contaminants generated indoor affect human body. Specially, indoor air contaminants generated from apartments are those exhausted from resident's indoor environment, closing materials and household. Indoor air environment in buildings is different according to pollution degree, existence availability of pollution source, ventilation amount, and meteorology. It is known that other contaminants more than about 900 kinds generate according to a kind of work or action in a room. Specially, nowadays buildings are well insulated and confidentiality-centered for environment protection and economical side. So indoor air contaminants are generated from indoor air pollution sauces of unprepared ventilation, human body carbon dioxide emissions, and various building materials. when these are accumulated in long term human body, it is harmful to resident's health, but awareness for this is very insufficient. Because bedroom is space that people inhabit for a long time by unconscious state and indoor environment occupies important part for resident's health and quality of life at sleep, the actual condition of air quality is investigated, improvement countermeasure is considered, and ventilation amount is analyzed. In this study, putting case that the most longest stayed time is sleeping time when people inhabit in the apartment, the air quality according to volume of bedroom space at sleep was measured and analyzed, and the data acquired will be the basis for improvement on this.

  • Numerous regulations have been introduced and a various kinds of institutional intervention have been made by government against the occupational safety and health problems. However, it was serious issue to the workers that what can be claimed by those who meet with apparently harmful and risky working conditions in their social systems. In the view point of employees, their right to be free from unacceptable risk and hazards has not been clearly defined. Therefore, workers have very limited rights to take any actions unless employer or government do their actions. It is believed that this undesirable conditions resulted from Jack of legal definition of workers' right to work in the safe and healthy environment. It has been found increased social pressure to make intervention to the industry to protect workers' health. Also, increased pressure has been kept for deregulation. This conflict lay the current situation in dilemma. The concept of the working environmental right has been developed and discussed in this study to overcome this trade-off confliction. It should be clearly separated between legal aspects and administrative and Policy area to make the regulations effective. Strong enforcement to the industry based on the law should be minimum, however, it should be practically effective in the aspect of workers' right. Administration and policy should be focused on supportive and leading activities to achieve the ultimate goal, safe and healthy working environment. It is concluded that establishment of working environmental right would satisfy workers and industry and it would result in improvement workers' environment and conditions.
