Purpose: This study was conducted to identify the effects of perceived health status and fatigue on family health, and to define the main factors that influence family health in middle aged women. Methods: Using a structured questionnaire, data were collected from 311 middle aged women. Descriptive statistics, Pearson's correlation coefficient, a t-test and ANOVA, a Scheffe test, and Stepwise multiple regression were conducted using the SAS package. Results: The mean score of perceived health status was 3.17($\pm$.63), while that of fatigue was 2.65($\pm$.49) and that of family health was 2.91($\pm$.37). Fatigue was negatively related to perceived health status and family health. In addition, perceived health status was positively correlated with the family health. The major factors that affect family health in middle aged women were perceived health status, economic status, mental fatigue, and satisfaction with marital status, which explained 27.2% of family health. Conclusion: These results indicate that, to increase family health, it is necessary to concentrate on improving the perceived health status and decreasing fatigue.

Purpose: The purpose was to identify the effects of a Tai Chi exercise program on physical fitness, fall related perception and health status among institutionalized elderly. Methods: A quasi-experimental research was carried out with a nonequivalent control group pretest-posttest design. There were 23 subjects in the experimental group and 24 in the control group. The data was gathered by structured questionnaires about fall related perception, and health status. Physical fitness was measured by an exercise therapist with a blind principle. Results: At the completion of the 12 weeks Tai Chi exercise program, flexibility (F=4.50, p=.00), and ability to balance (F=3.27, p=.00) had increased significantly. Fall related perception showed significant improvement in the fear of falling (F=-3.52, p=.00). Physical functioning (F=3.38, p=.00), role limitation-physical (F=2.67, p=.01), role limitation-emotional (F=2.47, p=.02). and general health (F=3.88, p=.00) in health status showed significant differences between the two groups. Conclusion: The study findings revealed Tai Chi exercise as a useful nursing intervention for elderly that enhances flexibility and balance, decreases fall related perception and also increases the health status. Further research is warranted to compare the potential effects of Tai Chi exercise and its health benefits from other types of exercise or martial arts.

This study investigated social determinants and their interaction effects on the health of school-aged children in diverse environmental factors pertaining to the individual, family, and peers from an ecological systematic perspective. Data were drawn from the first wave of the Korean Children and Youth Panel Survey (KCYPS) developed by the National Youth Policy Institute and conducted in 2010. Data were analyzed by descriptive statistics, Cronbach ${\alpha}$, correlation, and hierarchical regression analysis using SPSS ver. 18. The results from this study showed that sex and age were related to the health of school-aged children, as social determinants. Self-rated levels of the health of boys and younger children were more positive than girls and older children; in addition, levels of self-resilience, satisfaction of peer relation, and parenting rearing attitude were found to have a positive impact on self-rated levels of the health of school-aged children as protective factors. Especially, according to the result of interaction analysis between factors, self-resilience, and parenting rearing attitude were moderators of the effects on between sex and household income and self-rated level of the health of school-aged children respectively. The findings from this study suggested the need to expand the social intervention range to improve school-aged children's health.

The health effects of environmental and occupational exposure to steady magnetic fields is a matter of concern. The aim of this study was to evaluate the hematologic effects of exposure to steady magnetic fields at the electrolysis unit of a Copper complex. The population under study was the workers of the electrolysis unit of the copper refinery. The average steady magnetic field in the exposure group was 2.5 mT. The blood indices of workers exposure to steady magnetic fields after adjusting for confounders showed decreased white blood cells (except neutrophils) and increase in the number and volume of platelets. Red blood cells did not show any significant difference. Exposure to steady magnetic fields even in proposed safe limits may have hematologic effects on humans. There is a necessity for more research about the safe doses of exposure to magnetic fields.

Environmental contaminants are one of the important causal factors for development of various human diseases. In particular, the perinatal period is highly vulnerable to environmental toxicants and resultant dysregulation of fetal development can cause detrimental health outcomes potentially affecting life-long health. Perfluoroalkyl compounds (PFCs), emerging environmental pollutants, are man-made organic molecules, which are widely used in diverse industries and consumer products. PFCs are non-degradable and bioaccumulate in the environment. Importantly, PFCs can be found in cord blood and breast milk as well as in the general population. Due to their physicochemical properties and potential toxicity, many studies have evaluated the health effects of PFCs. This review summarizes the epidemiological and experimental studies addressing the association of PFCs with neurotoxicity and immunotoxicity. While the relationships between PFC levels and changes in neural and immune health are not yet conclusive, accumulative studies provide evidence for positive associations between PFC levels and the incidence of attention deficit hyperactivity disorder and reduced immune response to vaccination both in children and adults. In conclusion, PFCs have the potential to affect human health linked with neurological disorders and immunosuppressive responses. However, our understanding of the molecular mechanism of the effects of PFCs on human health is still in its infancy. Therefore, along with efforts to develop methods to reduce exposure to PFCs, studies on the mode of action of these chemicals are required in the near future.

Purpose: The purpose of this study was to investigate the effects and characteristics of health care programs for pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: This study was conducted according to the Cochrane Collaboration's systematic literature review handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. We searched eight international and domestic electronic databases for relevant studies. Two reviewers independently selected the studies and extracted data. For each study, information on the research method, participants, characteristics of the program, and results were extracted using a previously established coding table. The National Evidence-based Healthcare Collaborating Agency's risk of bias assessment tool for non-randomized studies was used to assess the risk of bias of the included articles. A qualitative review of the selected studies was performed because the interventions differed considerably and the measured outcomes varied. Results: Out of 128 initially identified papers, seven were included in the final analysis. The risk of bias was evaluated as generally low. Health care programs for pregnant women with GDM showed positive effects on blood glucose control. Anxiety and depression were reduced, and self-management and self-care behavior, self-efficacy, and maternal identity improved. Conclusion: Our study provides clinical evidence for the effectiveness of health care programs for pregnant women with GDM, and its results can be used to support the development of health care programs for GDM. More well-designed research is needed on GDM, especially studies that deal with emotional stress and apply a family-oriented approach.
