The purpose of this study was to identify the longitudinal mediating effects of peer attachment on the relationship between psychological school environment and children's sense of community. Data on 1,088 children were obtained from the 10^th, 11^th, and 13^th Panel Study on Korean Children in the 3rd 4th, and 6th grades. The data were analyzed using descriptive statistics, Cronbach's α, Pearson's correlation, a latent growth model, and a multivariate latent growth model. All analyses were conducted in SPSS 25.0 and AMOS 23.0. The principal results were as follows. First, children's peer attachment gradually decreased over time. Moreover, individual differences existed in the initial values and rates of change. Second, the psychological school environment in the 3rd grade positively influenced children's initial peer attachment, which then exerted a positive impact on children's sense of community in the 6th grade. Second, the psychological school environment in the 3rd grade negatively influenced children's rates of change, which also exerted a positive impact on children's sense of community in the 6th grade. Finally, the initial value and rates of change of peer attachment were significant mediating effects of the relationship between the psychological school environment in the 3rd grade and children's sense of community in the 6th grade. The findings highlight the necessity of creating a psychological school environment that develops peer attachment and a sense of community among children.

Background: The purpose of this study was to analyze the association between social support, psychosocial factors, and health behaviors of old adults in korean society. Methods: The data which was used in this study was extracted from the second wave of the Korean longitudinal study of aging in 2008. A total of 3,978 elderly aged 65 years or older were included in this study. We conducted $X^2$-test, t-test for the elderly health behavior in accordance with their social support and psychosocial factors. Also, multivariate logistic regressive analysis was performed in order to find how degree social support and psychosocial factors are associated with health behavior after adjusting sex, age, smoking (alcohol drinking), and other significant variables. The data was processed by SAS ver. 9.1 and Stata SE ver. 11. Results: Social support in older adults was significantly associated with lower smoking, alcohol drinking, exercise, and eating habit. Also, psychosocial factors were positively associated with smoking, alcohol drinking, regular exercise, and eating habit. Conclusion: health behaviors of old adults are likely to be vulnerable to social support and psychosocial factors. To increase effectiveness of the health policy for the elderly in Korea, it is important to adapt new strategy to include the empowerment of elderly's social networks, policy support to enhance subjective expectation, and life satisfaction.

Purpose: The National Health Insurance Service-National Sample Cohort and medical checkup data from 2002 to 2013 were used to evaluate the association between periodontal surgery for the treatment of periodontitis (PSTP) and vasculogenic erectile dysfunction (VED). Methods: Bivariate and multivariate logistic regression analyses were applied to a longitudinal retrospective database to assess the association between PSTP and VED while adjusting for the potential confounding effects of sociodemographic factors (age, household income, insurance status, health status, residence area, and smoking status) and comorbidities (diabetes mellitus, angina pectoris, cerebral infarction, and myocardial infarction). Results: Among the 7,148 PSTP within the 268,296 recruited subjects, the overall prevalence of VED in PSTP was 1.43% (n=102). The bivariate analysis showed that VED was significantly related to PSTP (odds ratio [OR], 1.99; 95% confidence interval [CI], 1.38-2.06; P<0.001), and this was confirmed in the multivariate analysis after adjusting for sociodemographic factors and comorbidities (OR, 1.29; 95% CI, 1.06-1.58; P=0.002). Conclusions: Subjects with a history of periodontal flap surgery had a significantly higher risk of VED, after adjusting for potential confounding factors. Further studies are required to identify the key mechanisms underlying the association between severe periodontal disease and VED.

Objectives: Previous observations propose that risk-taking behaviors such as cigarette smoking are prevailing among young people with chronic conditions including diabetes. The purpose of this study was to examine whether cigarette smoking is more prevalent among diabetics than non-diabetics and whether it differs by age at the time of diagnosis with diabetes from young adulthood (YAH) to adulthood (AH). Methods: We used US panel data from the National Longitudinal Study of Adolescent Health (Add Health Study) during the years 2001 to 2002 (Wave III, YAH) and 2007 to 2008 (Wave IV, AH). Multivariate logistic regression models were applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of cigarette use behaviors according to age at the time of diagnosis with diabetes, after adjusting for demographic and selected behavioral factors. Results: Of 12 175 study participants, 2.6% reported having been diagnosed with diabetes up to AH. Early-onset diabetics (age at diagnosis <13 years) were more likely than non-diabetics to report frequent cigarette smoking (smoking on ${\geq}20$ days during the previous 30 days) in YAH (OR, 3.34; 95% CI, 1.27 to 8.79). On the other hand, late-onset diabetics (age at diagnosis ${\geq}13$ years) were more likely than non-diabetics to report heavy cigarette smoking (smoking ${\geq}10$ cigarettes per day during the previous 30 days) in AH (OR, 1.54; 95% CI, 1.03 to 2.30). Conclusions: The current study indicated that diabetics are more likely than non-diabetics to smoke cigarettes frequently and heavily in YAH and AH. Effective smoking prevention and cessation programs uniquely focused on diabetics need to be designed and implemented.

Objective : To examine the association between dietary factors and cognitive impairment in older Korean women living in the community. Methods : Wave 2 data, from the Suwon Longitudinal Aging Study (SLAS), of 365 women aged 65 years or over, were used. The Korean version of the 30-point Mini-Mental State Examination (MMSE-K) was used to assess cognitive impairment (score$\geq$19). Dietary habits and frequencies of food group consumption were also examined. Results : A total of 67 women (18.4%) were found to be cognitively impaired. In bivariate analyses, nondietary factors, such as age, marital status, education, income, self-rated health, depression, emotional support, social activity, exercise, and dietary factors, such as self-rated nutritional status, frequency of beans and bean products and milk and dairy products consumption were associated with cognitive impairment. In the multivariate analysis, a higher frequency ($\geq$1 vs. <1 time/day) of beans and bean products (OR=0.48, 95% CI: 0.23-0.99) and milk and dairy products (OR=0.25, 95% CI: 0.10-0.61) consumption was inversely associated with cognitive impairment, after adjustment for non-dietary factors. Conclusion : These results suggest that dietary factors may play a significant role in cognitive impairment of older Korean women.

This study was designed to investigate the content of health behavior and to examine factors determining health behavior of nursing students(n=159) in relation to sociodemographic and cognitive variables. Cognitive variables were categorized into saliency of health, susceptibility to illness, and health locus of control. Data analysis prodecure included factor analysis and stepwise multivariate regressions using health behavior as dependent variables. Analysis showed; 1. As a whole, nursing students showed a tendency of lack in positive health behavior, especially in diet-related health behavior. 2. Multiple regression analysis revealed that the factors such as grade, saliency of health, and birth place were to be independently and significantly associated with health behavior: Upper grade students, high level of saliency, urban-born students tend to take health behavior positively. 3. The most influential factor among them was grade, but cognitive inspite of stereotype, poorly impact on health behavior with the exception health. We can guess the effect of education indirectively from these findindgs, but longitudinal studies need to consider the direct effect of education. The results also indicate that the respondents should be encouraged to take health behavior positively. The studies including more other cognitive variables would be conducted for the nursing students in relation to health behavior.

Purpose: Patterns of traditional medicine (TM) utilization vary depending on culture, historical significance, and regulations. We seek to understand how socio-demographic factors are related to TM use in Korea. Methods: The longitudinal cohort survey data of the Korea Health Panel (2008-2012) were used for the analysis. Information on TM included questions on 4 types of TM therapies used in South Korea (e.g., acupuncture, moxibustion and cupping, herbal therapies, and massage using hand). To adjust clustering across multiple observations per individual, individual random effects were used in the multivariate analysis. All analyses were performed using Stata 11.0. Results: A majority of Koreans (60%) used WM only during a year, and few people used TM only. Among TM users, most (93%) used it along with WM and 8% used TM only. Our regression analysis showed that female, age 34-64, low-educated, and sicker people were more likely to use TM. Conclusion: This study provides evidence on the relationship between TM utilization and socio-demographic factors.

Scheduled inspections of common crossings are one of the main cost drivers of railway maintenance. Prognostics and health management (PHM) approach and modern monitoring means offer many possibilities in the optimization of inspections and maintenance. The present paper deals with data driven prognosis of the common crossing remaining useful life (RUL) that is based on an inertial monitoring system. The problem of scheduled inspections system for common crossings is outlined and analysed. The proposed analysis of inertial signals with the maximal overlap discrete wavelet packet transform (MODWPT) and Shannon entropy (SE) estimates enable to extract the spectral features. The relevant features for the acceleration components are selected with application of Lasso (Least absolute shrinkage and selection operator) regularization. The features are fused with time domain information about the longitudinal position of wheels impact and train velocities by multivariate regression. The fused structural health (SH) indicator has a significant correlation to the lifetime of crossing. The RUL prognosis is performed on the linear degradation stochastic model with recursive Bayesian update. Prognosis testing metrics show the promising results for common crossing inspection scheduling improvement.

Background: Family values of a married woman may be related to her own depressive mood. Since depressive mood of a married woman is likely to exert a negative influence, in terms of mental health, on her, her family members, and the whole society's, it may be very important to explore the relationship between family values in married women and their depressive mood. Methods: In this study, we analyzed nationally representative 5,818 married women aged 20 years or older from the 4th panel data of 2012 Korean Longitudinal Survey of Women and Families. As for variables of interest, we constructed three family values variables: family-oriented view of marriage, individualistic view of marriage, and traditional view of marital roles. Then we employed multivariate logistic regression analyses to explore the relationship between family values and depressive mood, adjusting for family and socio-demographic factors. Results: In total, 804 married women (18.4%) had experienced depressive mood. All of the three family values variables were significant in their relationships with depressive mood. The women categorized as 'very weak' in family-oriented view of marriage were more likely to experience depressive mood than the women categorized as 'very strong' (odds ratio [OR], 1.98; 95% confidence interval [CI], 1.53-2.55). By contrast, the women categorized as 'very weak' in individualistic view of marriage (OR, 0.43; 95% CI, 0.33-0.55) and in traditional view of marital roles (OR, 0.68; 95% CI, 0.51-0.92) were less likely to experience depressive mood than their respective counterpart women categorized as 'very strong.' Conclusion: In Korea, married women's values towards marriage itself and roles between wives and husbands had significant associations with their depressive mood. This suggests that in order to improve mental health in married women, we need to take social and cultural dimensions into consideration along with public health interventions.
