Purpose: This study was based on social-role theory, and purposes were to investigate (1) how depression and health determinants vary with married and employed women, and (2) what factors contribute to depression according to family cycle. Methods: A stratified convenience sample of 765 married and employed women was recruited during May to August 2010. Study variables of depression, socio-demographic threatening factors, psycho-stimulating factors, and social-role related factors were measured via a structured questionnaire. Results: Prevalence rate for depression was 18.6%, with highest rate (25.4%) from elementary laborers. Greater levels of depression were related to women's occupation, higher life stress, and poorer health; lower social support and vulnerable personality; higher levels of social-role related stress. From multivariate analysis, women with preadolescents were the most vulnerable to depression affected by occupation, life stress, personality, and parenting stress. These factors (except for occupational class) combined with economic status, social support, and housework unfairness were significant for depression in women with adolescents. Conclusion: Depression among married and employed women differs by psycho-stimulating and social role relevant factors in addition to occupational class and family life cycle. Female elementary laborers and women with children need to have the highest prioritization for community mental health programs.

Purpose: The purposes of this study were to investigate the degree of presenteeism, which lowers productivity when call center workers come to work with illness, and analyze the factors influencing it. Methods: A survey was conducted for three months from July to September, 2013 to collect data. Questionnaires were distributed to 1,500 workers at 30 call centers in Seoul and Gyeonggi Province, of which were 1,274 returned and analyzed for the study. Results: The findings show that the call center workers scored 15.4 points out of the maximum 30 on presenteeism based on SPS-6. The study examined factors that affect the presenteeism of call center workers and identified inner emotional labor, depression, subjective health condition, age and turnover intention as those factors. Their presenteeism was low when they engaged in more inner emotional labor, and when they had a good subjective health condition. The presenteeism was high when they had a higher degree of depression, were young, and had a higher turnover intention. Conclusion: The findings call for a need to implement a mental health promotion program to resolve call center workers' depression at work, help them manage their emotional labor to lower their turnover intention, improve their subjective health conditions, and run a health management program to consider the uniqueness of the young age group in order to prevent their increasing presenteeism.

Indoor air quality is the dominant contributor to total personal exposure because most people spend a majority of their time indoors. The purposes of this study were to evaluate the alternative method for improvement of indoor air quality in house after coating titanium dioxide ($TiO_2$) photocatalyst for interior part of the house using nitrogen dioxide ($NO_2$) multiple measurements. To evaluate the alternative method in indoor environment, daily indoor and outdoor $NO_2$ concentrations of an apartment and a detached house were daily measured for consecutive 21 days in winter and summer, respectively, Another daily 21 measurements were carried out after $TiO_2$ coating on wall paper of interior part in houses. All $NO_2$ concentrations were measured by passive filter badges. Indoor air quality models using mass balance are useful tool to quantify the relationship between indoor air pollution levels, ambient concentrations, and explanatory variables. Using a mass balance model and linear regression analysis, penetration factor (ventilation rate divided by sum of ventilation rate and decay rate) and source strength factor (emission rate divided by sum of ventilation rate and decay rate) were calculated. Subsequently, the decay constants were estimated. In this study. magnitude of improvement of indoor air quality could be evaluated by decay constant.

The purposes of this study were to understand health-promoting behavior of client visiting health-promoting center, to identify the major subscales affecting performance in health promoting behavior to facilitate nursing intervention for health promoting of this population and to test Pender's Health Promotion Model. The subjects for this study were 177 sampled among clients from health-promoting center in General Hospital at Teajon. Data was collected by self-reported questionnaires from February 11 to May 22, 1998. Analysis of the data was done by frequency, t-test, ANOVA, Pearson Correlation Coefficient, Stepwise multiple regrssion using SPSS-PC. The results of the study were summarized as follows : 1. The mean score of performance in the health-promoting behavior was 109.22 and range was 71 to 170. The subscale of the highest mean score was self-actualization(30.77) and the subscale of the lowest mean score was exercise(10.50). 2. The most important variable in the health promoting behavior was the perceived self-efficacy. The perceived self-efficacy explained 15.8% of the variance in health promoting behavior. The combination of perceived self-efficacy, perceived barriers, religion, perceived benefits, perceived symptom, and age explained 43.5% of the variance in health promoting behavior. 3. In the relationships between individual characteristics and experience and health promoting behavior, age, religion, the significant differences in the subscale of the health promoting behavior ; sex, educational state, previous occupation, monthly income, marrital state, perceived symptom, and visiting plan of health-promoting center. 4. The health promoting behavior was statistically significant correlated with perceived benefits, perceived barriers, affect related to action, and perceived self-efficacy.

Purpose: This study sought to identify the utilization and confidence in assistive technology (AT) for pediatric physical therapists (PPTs) and pediatric occupational therapists (POTs) for the purpose of improving the utilization of AT in clinics. Methods: The subjects of this study were 167 therapists (98 PPTs and 69 POTs) who work at general hospitals, welfare centers, facilities for the disabled, and special education schools in Seoul and Gyeonggi province. The frequency analysis and chi-squared test were used. Results: This study found that both PPTs and POTs recognize that AT benefits infants with disabilities; however, they show low confidence in using AT. Applications of AT are concentrated on wheelchairs for mobility and assistance with seating position, with orthotics/prosthetics for both purposes. POTs were found to use a wider variety of AT devices. While both PPTs and POTs frequently select/recommend devices, both groups are less involved with delivery methods, manufacture of devices, and education on AT use. Conclusion: These findings show the actual conditions of utilization and confidence in AT of PPTs and POTs deeply involved with AT, and emphasize that AT training is essential for pediatric treatment by comparing domestic and foreign studies.

The primary purpose of the general duty clause is to offer an extra measure of protection to employees in the workplace. Most standards implemented under OSHA are targeted at a specific hazard. The general duty clause, however allows inspectors to cite employers for exposing its employees to a recognized hazard that has not been specifically addressed in the regulations. Congress intended the general duty clause to be a limited means of advancing the purposes of the OSHAct. But OSHA has not always regarded the general duty clause as the limited means for protecting the safety and health of employees that Congress intented. OSHA attempted to expand the scope of the general duty clause, at times improperly, to make it a more flexible enforcement tool. OSHA's interpretation of each of the restrictions on the scope of the clause has changed over the years. In recent years the general duty clause has been utilized as a sometimes controversial mechanism for enforcement of safety guidelines that have not yet been specifically addressed by statute or regulation. The most notable example of this was application of the general duty clause to ergonomic hazards.
