Traffic-related air pollutants and particulates from diesel exhaust cause for increasing respiratory health problem. Recent epidemiologic studies have reported adverse effects of urban air pollution on various aspects of respiratory health. Bus or truck terminal workers have high probability of exposure to diesel exhaust particle than general office worker. This study was designed to evaluate the relationship between pulmonary function of people who working at the high-density area of diesel vehicles and pulmonary function of people who working at general office in Seoul. So, this study explored the effects on people with exposure to diesel traffic or exposure to diesel traffic, through the pulmonary function test (PFT). There were significant difference in Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second ($FEV_1$) between high-exposure group and control. High-exposure to diesel particle were increased risk of reduction in pulmonary function in this study. These results provide the necessity additional research that manage people who working at the high-density area of diesel vehicles.

Indoor and outdoor nitrogen dioxide (NO$_2$) concentrations were measured and compared with measurements of personal exposures of 95 persons in Seoul, Korea and 57 persons in Brisbane, Australia, respectively. Time activity diary was used to determine the impact on NO$_2$ exposure assessment and microenvironmental model to estimate the personal NO$_2$ exposure. Most people both Seoul and Brisbane spent their times more than 90% of indoor and more than 50% in home, respectively. Personal NO$_2$ exposures were significantly associated with indoor NO$_2$ levels with Pearson coefficient of 0.70 (p＜0.01) and outdoor NO$_2$ levels with Pearson coefficient of 0.66 (p＜0.01) in Seoul and of 0.51 (p＜0.01) and of 0.33 (p＜0.05) in Brisbane, respectively. Using microenvironmental model by time weighted average model, personal NO$_2$ exposures were estimated with NO$_2$ measurements in indoor home, indoor office and outdoor home. Estimated NO$_2$ measurements were significantly correlated with measured personal exposures (r = 0.69, p＜0.001) in Seoul and in Brisbane (r = 0.66, p＜0.001), respectively. Difference between measured and estimated NO$_2$ exposures by multiple regression analysis was explained that NO$_2$ levels in near workplace and other outdoors in Seoul (p = 0.023), and in transportation in Brisbane (p = 0.019) affected the personal NO$_2$ exposures.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.

Methods For this, 9 male and 15 female participated in the foward head posture with tension type headache. Each group consisted of 3 male and 5 female. Groups are divided into groups, such as muscle relaxation therapy, joint movement therapy, muscle relaxation and joint movement therapy. After intervention for each group for a month, we measured neck movement and head disability index and neck disability index 2 week. SPSS 23.0 (IBM Corp., Armonk, NY, USA) was used for data analysis. The one-way repeated analysis of variance (ANOVA), one-way ANOVA, compared t-test was used for statistical analysis. Results Three intervention groups have brought improvements in neck movement and daily life comfort. There is significant difference in the improvement of neck extension and change in neck disability index between 2 and 4 weeks in the joint movement approach compared to muscle relaxation approach, muscle relaxation and joint movement approach. Conclusions Office workers are exposed to tension type headache. However, muscle relaxation approach and joint movement approach can improve neck movement and daily life comfort.

This study was designed to search for the direction to develop housing service which assists the older people to live independently in their community and provides the systematization of community care. The subjects of the research include 533 older people between the age of 60 to 79 residing in Seoul and 84 welfare officials at a dong(in)-office and 67 social workers working at comprehensive social welfare institutions. The results were as follows: Both demanders and deliverers recognized that housing service for older people was necessary for community care, and, in particular, the deliverers had higher degree of necessity as people charged in welfare service. The most needed service was community alarm service which currently is proceeded partially for low-income and living-alone olders. It needed to expand the scope of the people to be served. It appeared that the need for inside safety measures rather than for housing space or structural problems. It requires less effort and cost for those who need simple repair, such as safety grips or slippery protection, and safety checks. Among financial support services, the need for tax benefits appeared the most necessary service for the older people. It suggested that more 'direct' financial support service is needed for the elderly people.

This study analysed the effect of mothers' work status on time use in child care and use of market child care services. There were two major questions: Do self-employed (and family worker without being paid) mothers have a flexible work schedule and so can they care her child(ren) well? If it is true, is the work status as self-employee related to non-market child care services? To answer these questions, 1,196 samples were selected from the Time Use Data of 1999, which had been administered by Korea National Statistical Office. Major results were as follows: First, a mother who is family workers without being paid made time to care children frequently more than wage earners. Second, according to regression analysis, mothers' work status was one of the important variables to explain child care activity frequency. Third, among categories of child caring ('physical caring', 'non-physical caring', and 'caring of the others'), mothers spent more frequently in 'caring of the others', and had higher probability to use market child care services. But the more frequently a mother made time in 'non-physical caring' for her child, the lower probability to choose market child care services. In conclusion, it was certain that self-employed mothers benefit from a flexible time schedule at work places. But the relationship of child care activity frequency with use of market child care services was inconsistent.
