The welders and car painters are frequently exposed to heavy metals such as lead, zinc, cadmium and chromium, and those are a major source of heavy metal poisoning. This study was carried out to investigate the relationship of the heavy metal level in blood by age, working duration, and smoking status among 105 industrial workers and 88 general people in Gyeongnam province from October 2003 to October 2004. The heavy metal level in blood was analyzed by atomic absorption spectrophotometer. Mean blood lead level in exposed group and control group was 8.40±4.67μl/dl, 1.82±1.35μl/dl, respectively. Mean blood zinc level in exposed group and control group was 9.43±5.38 ㎍/ml, 2.89±1.79㎍/ml, respectively. Mean blood cadmium level in Exposed group and control group was 1.53±1.05μl/dl, 0.60±0.49 μl/dl, respectively. Mean blood chromium level in exposed group and control group was 0.89±0.76μl/dl, 0.68±0.63μl/dl, respectively. Lead, zinc, cadmium and chromium level in blood of exposed group was significantly higher than that of control group. In the comparison of smoking status, lead, zinc and cadmium level of smoker's was significantly higher than that of non-smoker's. Comparison of heavy metal level by age, lead, zinc, cadmium level in 40's, 50's (exposed group) in blood significantly higher than that of 20's, 30's. In exposed group, working duration has no significant difference. In conclusion, smoking was the most hazardous factor to elevate in blood heavy metal levels.

This study investigates the balance between work and family, and the happiness of married working women who have preschool-aged children. Data were collected from 321 questionnaires that consisted of three parts: 1) basic demographic variables, 2) family-life variables, and 3) working-life variables. SPSS 21.0 was used for the statistical analysis. The variables that were identified to have a statistically significant impact on the balance between work and family were income, age of first child, time spent on housework and childcare on weekdays, time spent on housework on weekends, family-friendly service in the workplace and flexibility of work schedule. 2) The variables that were identified to have a statistically significant impact on happiness were age, income, time spent on housework on weekends, satisfaction with spouse's participation in housework and childcare, average working time, family-fiendly service in the workplace, flexibility of work schedule, and balance between work and family. The majority of the variables that influence balance between work and family, and happiness related to aspects of work, such as family-fiendly service, flexibility of work schedules, and average working time. The results also found that the load of housework and childcare on weekends is a heavy burden for working women. Further research needs to focus on developing the extending index of happiness including the measure of balance between work and life. In addition, further studies with more varied groups need to be conducted.

The construction industry is an industry in which skilled construction workers should be secured and trained because of the quality and productivity of buildings, but the negative image makes it difficult to supply and demand skilled construction workers. In response, this study derived the factors influencing the intention of transferring construction workers to other occupations and investigated ways to improve the prevention of leaving other occupations by age of construction workers. The factors influencing the turnover of construction workers have also been derived, and work overload, salary, workplace stability, and employment competitiveness have a significant impact on the intention of new employees to change jobs. According to a survey on ways to improve the prevention of leaving other jobs, those in their 20s and 30s are "improving working conditions, such as providing holidays, paying overtime, compliance with working hours," and those in their 50s and 60s.

This research explores different non-work trip characteristics between the elderly group (65+) and the working age group (20-64) using heteroscadastic ordered logit model. The analysis is based on travel survey data of Seoul Metropolitan area in 2006. The results show that age induces heteroscadasticity and the model provides a better fit than ordered logit model. The factors increasing the number of non-work trip of the elderly were driver's license and household income. Conversely, the number of non-work trips decreased in those groups that were male, with a job, in aging, and with the number of preschool children. The factors having opposite effects (increased the number of non-work trips in the working age groups and decreased in the elderly group) between the elderly group and working age group were age and job.

This qualitative case study examines how mid-life housewives perceive age, react to aging, and experience the changing of their appearance that comes with age. The participants of this study were eight housewives four full-time housewives and four working housewives in middle adulthood. This study was conducted through in-depth interviews that were based on an unstructured questionnaire, and the data was collected from January 2010 to October 2010. Findings are as follows: during mid-life, housewives continue to exert efforts toward self-development, and toward self-actualization that can unleash the potential of their "multi-self". The housewives of the Entering Middle Adulthood self-actualization period believe that the material self as manifested in appearance is the most important component of the multi-self. Indeed, both groups of housewives thought a great deal about the criterion of appearance for their age and were concerned about others' viewpoints, social stereotypes, the appearance "norm," and other characteristics related to appearance. The full-time housewives made efforts to improve their social selves, and the working housewives tried to enhance their spiritual selves. The viewpoints of husbands are often internalized into housewives' internal points of view; therefore the relationships of housewives with their husbands were crucial both to the confidence the women felt in their appearance, and to their satisfaction in life.

Purpose: The purpose of this study was to compare health promoting behavior between working and non-working mothers with infants and toddlers, and to investigate factors affecting the mothers'health promoting behavior. Methods: This descriptive study was conducted through conveniently sampled 403 women who visited the child health clinics at two public health centers. The questionnaire included the Health Promoting Life Style Profile (HPLP) and a visual analogue scale for subjective health status. ANCOVA, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted using SPSS ver. 21. Results: Working mothers' average HPLP score ($2.30{\pm}0.37$) was higher than non-working mother's ($2.15{\pm}0.37$). The score of the physical activity subscale was lowest among the subscales and there was a difference between the two groups. Subjective mental health status was the only predictor of working mothers'health promoting behavior, and it explained 23.2% of variance in health promoting behavior. Subjective mental health status, education, and age were the predictors of non-working mothers' health promoting behavior and they explained 27.2% of variance in health promoting behavior. Conclusion: According to the findings, both working and non-working mothers' health promoting behaviors were low. To promote mothers' health, it is necessary to develop diverse community health promotion programs to support mothers.
