Objectives: This study performed to analyze general characteristics, environmental factors, and health promoting lifestyle by smoking behavior among university students. Methods: In 2011, interview survey was conducted with 700 Korean students of university and college in located 7 metropolitan cities and the biggest province (Gyeonggido). To examine the factors related to smoking behavior, it collected environmental factors, health promoting lifestyle, and mental health. Multiple logistic regression analysis for survey data identified the difference of smoking behavior. Results: The 20.4% of university students was current smoker. Smoking rate of male was higher than that of female. The university students residing in Seoul and surrounding areas were less likely to have smoking behavior than them residing in local areas. In multiple regression models, difference by gender, academic year, college level, college type, region, secondary smoking exposure time, health status, monthly drinking, alcohol use disorder, and eating breakfast remained significantly (p<0.01, p<0.05). Conclusion: Future efforts should be focused on association between health risk factors and environment factors in physical, mental, and social aspects. To achieve this, we will need to provide the integrated health promotion program to decrease smoking problems of university students.

Purpose: This study investigated the factors influencing mental health among university students based on ecological perspectives. Method: The subjects for this study were 416 students in two colleges in K province. The instruments used for measurement were: Symptom Checklist (Derogatis, 1977), Ego Resilience Scale (Block & Block, 1980), Perceived Stress Inventory (Cohen, Kamarck, & Mermelstein, 1983), and Social Support Scale (Park, 2002). The data was analyzed using the IBM SPSS program. Result: Ego resilience and perceived stress as intrapersonal factors and friends' support as interpersonal factor were the significant predictors of mental health. It was showed that these factors explained 47% of mental health. Conclusion: This study suggests that the factors influencing mental health are both intrapersonal and interpersonal factors. Thus, the findings of this study provide the basic data to develop a program for mental health of university students based on ecological perspectives.

Normal balance is defined as state in which the body is equlilibrium. It is complex motor control task, requring integration of sensory information, neural processing, and biomechanical factors. There are major two factors contribute to balance control, the neurological and the musculoskeletal. The neurological factor provides the sensory processing and motor output mechanisms that are the neurophysiological basis for response. The musculoskeletal factor provides the mechanical structure for response. When all components of two factors are operating effectively, the postural response should be appropriate and effective for good balance control. Therfore, balance can be influenced by above all factors. In addition, balance can be also influenced by muscle tone, hearing, physiological factors, and environmental factors. Physical therapists must understand factors of balance control so that we can accurately assess balance. Therefore, physical therapists have to develop useful balance measurement tools to evaluate balance.

This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.

Exposure factors based on the Korean population are required for making appropriate risk assessment. It is expected that handbooks for exposure factors will be applied in many fields, as well as by health department risk assessors. The present article describes the development of an exposure factors handbook that specifically focuses on human activities in situations involving the possible risk of exposure to environmental contaminants. We define majour exposure factors that represent behavioral patterns for risk assessment, including time spent on routine activities, in different places, on using transportation, and engaged in activities related to water contact including swimming, bathing and washing. Duration of residence and employment are also defined. National survey data were used to identify recommended levels of exposure factors in terms of time spent on routine activities and period of residence and employment. An online survey was conducted with 2073 subjects who were selected using a stratified random sampling method in order to develop a list of exposure factors for the time spent in different places and in performing water-related activities. We provide the statistical distribution of the variables, and report reference levels of average exposure based on the reliable data in our exposure factors handbook.

Background: In modern society, depression is serious issue that causes socioeconomic and family burden. To decrease the incidence of depression, risk factors should be identified and managed. Among many risk factors for depression, this study examined socioeconomic risk factors for depression. Methods: We utilized first (2006), second (2008), and third (2010)-wave data from the Korean Longitudinal Study of Aging (KLoSA). Depressive symptom was measured with the 10-item Center for Epidemiological Studies Depression Scale, Short Form (CES-D-10) in the survey in 2008 and 2010. Three risk factors including job security, employment type and monthly income were measured in the survey in 2006. The association between risk factors and depressive symptom was analyzed by Cox proportional-hazard model. Results: We analyzed data from 1,105 workers and hazard ratios (HRs) for 3 risk factors were significant entirely. In addition, regular worker with high income group is the most vulnerable group of poor job insecurity on depression among male workers (HR: 1.73; 95% confidence interval [CI]: 1.07-2.81). Finally, HRs for 7 groups who had at least 1 risk factor had higher HRs compared to groups who had no risk factors after stratifying 3 risk factors. In the analysis, significantly vulnerable groups were total 5 groups and the group who had highest HR was temporary/daily workers with poor job security (HR: 2.51; 95% CI: 1.36-4.64). The results concerning women, regardless of job type, were non-significant. Conclusions: This study presented one or more risk factors among poor job security, low income, temporary/daily employment type increase hazard for depressive symptom in 2 or 4 years after the exposure. These results inform policy to screen for and protect against the risk of depression in vulnerable groups.

Objectives: This paper aims to identify depressive or stress related symptoms and its associated risk and protective factors among marriage immigrant women in Korea. Methods: The study participants were 490 immigrant wives from '2012 Survey of Foreign Residents in Korea'. The participants completed self-administered questionnaires on socio-demographics, health status, family members' related factors, and other environmental factors. Results: Difficulties on child nursing, finance, family conflict, and experience of physical or verbal violence were significant risk variables to the depressive stress related symptoms. Family life satisfaction, discussion about troubles with Koreans, healthy status, social trust, and discussion about troubles with people from home country were the significant protective variables to mental health. However economic activities were not protective factors but risk factors. Conclusions: Mental Health promotion programs for marriage immigrant women and their family members need to consider the family and community related protective mental health factors and develop supportive system with pre-existing programs and policy modification.

Purpose: The purpose of this study was to review and identify factors relevant to workplace bullying in nursing. Methods: Twenty-three studies that met the criteria were selected from a sample of twenty-six studies. These articles were retrieved from a central literature databases (N=13,241). The total correlational effect size (ESr) for each related factor was calculated from Fisher's Zr. A funnel plot inspection (similar to scatter plot) with a trim-and-fill method was used to assess the publication bias of the meta-analyzed studies. Results: From the systematic review, fifty-one factors were identified as having an influencing effect. Fourteen factors (five individual and nine organizational factors) were eligible for meta-analysis. The individual factors included, self-esteem (ESr=-.31), psychological capital (ESr=-.26), and marital status (ESr=-.06) which were significantly correlated with workplace bullying. Organizational factors included, organizational tolerance (ESr=.48), supervisor incivility (ESr=.47), job stress (ESr=.46), group morale (ESr=-.36), group support (ESr=-.35), supervisor leadership (ESr=-.35), group identity (ESr=-.33), and structural empowerment (ESr=-.27). These factors were significantly correlated with workplace bullying. There were no publication biases except for both individual and organizational factors. Conclusion: Organizational factors have more of an greater impact than individual factors on workplace bullying. The results of this study support the need for intervention at the organizational level.
