Purpose: The number of Korean adolescents engaging in gambling is increasing, especially among out-of-school adolescents. This study aimed to identify patterns of gambling activities and factors related to specific subgroups of out-of-school adolescent gambling activities. Methods: This descriptive study analyzed secondary data from the 2015 Korea Youth Gambling Problem Survey, including 1,200 out-of-school adolescents. Latent class analysis was conducted to identify patterns of gambling activities. The factors related to gambling subgroups were verified with multinomial logistic regression. Results: Three latent classes of gambling activities were identified: rarely gambling (RG), immediate gain gambling (IGG), and broad gambling (BG). These subgroups differed significantly in terms of gender, age at and type of first gambling experience, number and type of gambling activities, gambling frequency, time and money spent on gambling, problem gambling severity, and motivation for gambling. Compared to the RG subgroup, both the IGG and BG subgroups were strongly associated with an older age at the first gambling experience. Conclusion: Out-of-school adolescents who first gambled at an older age and who gambled mainly in order to gain money immediately were at risk of problem gambling. Developing strategies for early screening and referral to professionals is necessary to prevent gambling problems from worsening.

This study investigates the stability of professionals' cost variability factor-rankings across different levels of cost-variability and response scenarios. Descriptive statistics are used to examine the stability of factor-ranking for 20 cost variability factors and a Multinomial Logistic (MNL) regression model was implemented to examine the stability of cost variability factors across three cost variability levels. The finding on the descriptive statistics indicated that professionals' factors-rankings are stable only for external factors. The MNL regression results on factor-stability suggested that 8 out of the 20 evaluated factors were unstable determinant of lower cost variability levels. These factors are "risk associated with the project", "personal bias and poor professionalism of the estimators", "limited time available to complete the project", "lack of skills and experience by estimator" "geographical location of projects", "incomplete & rush designs for estimate", "unforeseen or unexpected site constraints", "high class bidders for the contractors". Similarly lack of experience and large size projects were observed to be unstable as well. These observations suggest that professionals' view on pre-tender cost variability factor-ranking yields unstable factor rankings hence should not be relied upon as the only mechanisms to mitigate cost related risks in construction projects.

This study investigates the factors affecting job seekers' utilization of social networks in Korean job markets by using the East Asia Social Survey on People's Work Life: South Korea data collected in 1996. If employees are analyzed as a whole, social networks have been used more frequently than formal means and direct application. Results of the multinomial logistic regression largely show that job seekers who occupy better positions in job markets have used social networks less frequently. This is due to the characteristics of Korean job markets: (1) Korean job markets are clearly divided by several criteria, and (2) in the sectors of job markets which provide better socioeconomic rewards, the competition through formal means is the main path of getting jobs.

Purpose: This study was conducted to characterize the influence of achievement motivation and the parent-child relationship on ego identity in Korean nursing students. Methods: The participants were 217 Korean nursing students in the first and fourth year of university. Data were collected through self-report questionnaires composed of items assessing ego identity, achievement motivation, the parent-child relationship, and demographic characteristics. The data were analyzed using descriptive statistics, one-way analysis of variance, the $x^2$ test, and multinomial logistic regression analysis. Results: Ego identity was related to achievement motivation; moreover, the achievement motivation of students with moratorium and achieved identity status was significantly higher than that of students with low-profile moratorium and diffused identity statuses. Ego identity was not related to the mother-child relationship, but the father-child relationship of students in foreclosure was significantly higher than that of students with diffused identity status. The factors influencing achieved identity compared to diffused identity were achievement motivation, year in school, satisfaction with school, and having religious beliefs. Conclusion: These findings indicate that nursing students' ego identity attainment was more influenced by achievement motivation than by the parent-child relationship. It emphasizes that highly motivated students can develop their own identities regardless of the parent-child relationship.

Purpose: The purpose of study was to examine the relationship between obesity and its associated factors (psychiatric symptom, duration of illness, type of medication, physical activity, dietary habits, depressive symptom, and stress) in patients with chronic mental illness registered to community mental health welfare centers. Methods: This was a cross-sectional correlation study using a convenience sampling. A total of 392 participants were recruited from community mental health welfare centers. The obtained data were analyzed using binary and multinomial logistic regression. Results: Atypical antipsychotic medication, duration of illness, dietary habits (overeating, and drinking instant coffee) were significantly contributed variables into body mass index (BMI) obesity. Atypical antipsychotic medication and instant coffee were significantly related to abdominal obesity. Conclusion: These results emphasized the needs of tailored obesity-preventive management for the community-dwelling patients with chronic mental illness, topically focusing on the administration of atypical antipsychotic medication, duration of illness, and dietary habits.

The purpose of this study is to identify variables that influence the family decision-making process when planning a wedding. In this case the planning refers to: the procedure of the wedding: yedan, which means presents for parents and relatives: and yemul, which means wedding gifts. Decision-making was categorized into four types: decisions led by the bride and groom, decisions led by the groom's parents, decisions led by the bride's parents, and co-decisions by the two families. Resource theory was used as a conceptual framework. Data for this study were collected from 305 adults who got married after 1977 and lived in Seoul. Multinomial logistic regression models were used to analyze the data. Variables determining the decision-making of wedding procedure were the groom's age at marriage, the level of familism, and the major source for the wedding expenses. When it came to decisions on yedan, gender, the bride's year of education, and the major source for wedding expenses had significant influence on the decision-making. Variables that affected decision-making on yemul were the bride's year of education, and the major source for wedding expenses. This study suggested the power structure among bride, groom, and their parents through variables which exert influence on family decision-making.

Purpose: This study was conducted in order to identify factors that influence depression for low-income elderly who live at home from the International Classification of Functioning model (ICF). Methods: The subjects were 205 elderly people living at home in two public health centers located in metropolitan cities. Subjects were divided according to their depression scores, which were measured using the GDS-short form, including normal, risk, and depression groups. Each variable was consistent with factors of the ICF model, including health condition, individual factors, environmental factors, body function, activities, and participation. Data were collected using structured questionnaires. ANOVA, $x^2$, Pearson's correlation coefficient, and Multinomial logistic regression with IBM SPSS 21.0 were used for analysis of the data. Results: Statistically significant differences were observed among normal, risk, and depression groups regarding personal factors. Gender, education level, numbers of diseases, perceived health, life satisfaction, and social support were identified as the variables that had a significant impact on depression of low-income elderly living at home. Conclusion: Results of this study indicate that there is a need for construction and implementation of strategies that strengthen life satisfaction and social support in order to lower depression of low-income elderly.

This study explored a typology (or time allocation), investigated personal and work characteristic differences among time allocation types, and identified determinants of time allocation types of married working women with a preschool child. The data source for this research was the 2014 Time Use Survey conducted by Statistics Korea. We analyzed 368 time diaries (184 for weekdays and 184 for weekends) using frequency, mean, cluster analysis, chisquare, analysis of variance (ANOVA), Duncan's test, and multinomial logistic analysis. The results of this research are as follows. Time allocation of married working women with a preschool child was classified into three different types of 'work-centered,' 'work-family balanced,' and 'family-centered.' The work-centered type accounted for 14.7% of total respondents, and compared with other types, this type of people spent more time working, and less time doing house-work, caring for family, and having leisure. The work-family balanced type represents more than half of the total, and spend more time working on weekdays and house-working, having leisure on weekends. The family-centered type represents 28.8%, and spends most of the time doing house-work and caring for family on both weekdays and weekends. Occupation, employment status, monthly income, and weekly hours of work were different for each type. Occupation, employment status, perception of lack of time, health condition, and weekly hours of work were identified as determinants for each type.

Objectives: This study was conducted to examine the association between health condition and leaving the labor market among middle-aged and older adults in South Korea. Methods: Data was obtained from individuals aged 45 years and older participating in the 2006 and 2008 Korean Longitudinal Study of Ageing. We used various health measures including chronic diseases, comorbidities, traffic accident injuries, disabilit of instrumental activities of daily living, depressive symptoms, and self-rated health. The odds ratios of job loss, and retirement, versus employment were calculated using multinomial logistic regression by each health measure. Results: In our cross-sectional and longitudinal analysis, health problems related to physical disabilities had the greatest effect on leaving the worksite. A shift in health condition from good to poor in a short period was a predictor of increased risk of unemployment but a persistent pattern of health problems was not associated with unemployment. Women with health problems showed a high probability of retirement, whereas among men, health problems instantly the possibility of both job loss and retirement. Conclusions: Health problems of middle aged and older workers were crucial risk factors for retirement and involuntarily job loss. Especially functional defect and recent health problems strongly and instanty affected employment status.

Background: Smokeless tobacco consumption is one of the causes of oral cancer. The aim of this study was to determine the prevalence of smokeless tobacco consumption among male students of Zahedan universities and associated factors in 2012. Materials and Methods: In this cross-sectional study, 431 students were selected from the universities of Zahedan using multi-stage random cluster sampling. The data collection tool was a questionnaire including questions about demographic information, history of smokeless tobacco consumption, and awareness of smokeless tobacco hazards. Data were analyzed by SPSS19 using Chi-square test and multinomial logistic regression, with p<0.05 considered significant. Results: At the time of conducting this study, 102 students (23.7%) had already consumed smokeless tobacco and 49 students (11.4%) were current users (consuming at least once in 30 days before the study). There was a significant relationship between history of smokeless tobacco consumption, university/college, place of living, mean GPA, and mother's education level (p<0.05). Also there was a significant association between knowledge and prevalence of smokeless tobacco use (p<0.001). Conclusions: There is a relatively high prevalence of smokeless tobacco consumption among the male students of universities of Zahedan, which shows the need to emphasize the provision and implementation of prevention programs in universities.
