  • Purpose: The purpose of this study was to investigate parents' perceptions and attitudes regarding a screening test for and subsequent management of students' emotional and behavioral problems. Methods: A descriptive research design was used, and included disproportional stratified and cluster random sampling. The sample comprised 223 parents of elementary, middle, and high school students. Data were analyzed using descriptive statistics, Chi-squared test, and ANOVA with SPSS/WIN 21.0. Results: Overall, parents responded that they knew of the goals, types, and tools of screening tests for students' emotional and behavioral problems. In total, 64.6% of parents reported having information for the screening test in advance. Only 13.5%(n=30) of students had emotional and behavioral problems in the last year. Among these students, 56.7%(n=17) were referred to mental health facilities but only 29.4%(n=5) of them received ongoing management from these facilities. Conclusion: These findings suggest that parents should receive information about the screening test for and subsequent management of students' emotional and behavioral problems. Health professionals need to build strategies to provide ongoing management for students who have emotional and behavioral problems.

  • Purpose. The purpose of this study was to determine the relationship between peer and parental factors and smoking behavior of adolescents in urban cities and to investigate whether there are gender differences. Methods. A stratified and random cluster sampling design was used to obtain a cross-sectional sample of high school students in two urban cities. The sample consisted of 512 Korean adolescents (256 boys and 256 girls) aged 15 to 18 (mean age 16.7$\pm$.58). Self-reported questionnaire consisted of adolescent smoking behavior, peer smoking and alcohol use, parental smoking and alcohol use, father-mother-peer relationships and perceived social support from peers and parents. Multiple logistic regression analysis was used to examine the hypothesized model. Results. The findings showed that peer and parental factors accounted for $30.3\%$ of the variance in adolescent smoking and peer smoking was most strongly associated with adolescent smoking behavior (OR = 10.18). In addition, peer smoking (OR = 4.71), peer alcohol use (OR = 4.21), and peer relationships (OR = 1.03) were significantly associated with boys' smoking behavior. In girls, peer smoking (OR = 26.50) and parent smoking (OR = 5.48) were significantly associated with smoking behavior. Conclusions. Consistent with previous findings, peer smoking is a significant factor on adolescent smoking. Specifically, boys would be more influenced from peers than girls. Therefore, smoking prevention programs for adolescents might be focused on the social context such as, resisting to peer pressure and enhancing the self-efficacy to control.

  • Objectives : To investigate the information searching behavior of health care consumers according to sociodemographic characteristics. Methods : A questionnaire survey was conducted of 1,507 persons who were selected through a multi-stage stratified area cluster sampling of the Republic of Korea, excluding the province of Jeiu-do. Personal were conducted through a door-to-door survey between 27 July and 10 August 1999. Results : 80.5% of respondents used more than one source of information and those $40\sim59$ years of age, female, a housewife or student and those who claimed a religion demonstrated more active information searching behavior. A personal informer was used significantly more in those $20\sim39$ years old, female, and those who claimed a religion. Clerical workers, those with post-secondary education and a monthly income greater than 2,000,000 won ($1500) were more actively used a public informer. Low socioeconomic status and older persons used an experimental informer when they chose a health care institution. Conclusion : Regardless of the sociodemographic characteristics, personal and experimental informers were the most useful source of information. Because appropriate information was not easy to obtain, the health care consumer was dependent upon word-of-mouth communication(personal informer) when using health care services.

  • Purpose: The purpose of this study was to empirically test a model of associations linking locations and competition among nursing homes (NHs), mediated by facility grade and registered nurse (RN) turnover, on activities of daily living (ADLs) in Korean NHs. Methods: This study used a cross-sectional design to identify causal factors on NH residents' ADLs. Data were collected from June 2017 to August 2017. A disproportionate stratified cluster sampling method of NHs across Korea was used to gain representation. The collected data consisted of location and the Herfindahl-Hirschman Index (HHI), RN turnover rate, facility grade, and NH residents' ADLs. Results: All pathways affecting ADLs were not significant, and the effect on facility grade was significant in RN turnover (β = -.59, p < .001). RN turnover associated negatively with facility grade. In other words, the higher the RN turnover, the worse the facility grade. Conclusion: This study is the first to examine the impact of location and HHIs, mediated by RN turnover rate and facility grade, on NH residents' ADLs. To improve residents' ADLs, subsequent studies are needed to identify the factors affecting ADLs utilizing other variables because this study did not identify factors that affect ADLs.

  • This study empirically examined the moderated mediation effect of volunteer time in the effect of school maladjustment on juvenile delinquency through depression as negative emotions. For empirical confirmation, 7,052 individuals were collected by stratified multi-stage cluster sampling among 4th to 6th grade elementary school, 1st to 3rd grade junior high school, and 1st to 3rd grade high school students in May 2015. This data was used for analysis. The results of the analysis are as follows. First, school maladjustment directly affects juvenile delinquency and indirectly influences juvenile delinquency through depression. In other words, the higher the school maladjustment, the higher the juvenile delinquency. Also, the higher the school maladjustment, the higher the depression, and the higher the depression, the higher the juvenile delinquency. Second, the volunteer time has a significant effect on juvenile delinquency through interaction with the depression. In other words, it was proved that the moderated mediation effect of volunteer time in the effect of school maladjustment on juvenile delinquency through depression as negative emotions. Based on this, policy implications were examined.

  • Purpose: This study compared health behaviors and health-related clinical characteristics between individuals with normal glucose levels without diabetes and those with undiagnosed diabetes. Factors that were associated with undiagnosed diabetes were identified by sex. Methods: This was an observational study with a cross-sectional design based on data from the eighth Korea National Health and Nutrition Examination Survey, which used a stratified, multi-stage, cluster-sampling design to obtain a nationally representative sample. Multiple logistic regression analysis was employed to compute the odds ratios of health behaviors and clinical characteristics to identify risk factors for undiagnosed diabetes. Results: The overall prevalence of undiagnosed diabetes was 5.2% (weighted %, n = 700, p < .001). Among individuals with undiagnosed diabetes, 58.3% were men. Univariate logistic regression for undiagnosed diabetes identified sex, age, house income, educational level, and triglycerides as influencing factors. In multiple logistic regression by sex, the factors associated with undiagnosed diabetes in men were age, perceived health status, a diagnosis of angina, and triglycerides. Conclusion: Strategies should be targeted to improve health behaviors and clinical characteristics for specific age groups, men in bad perceived health status, women with high systolic blood pressure, and high triglycerides. Moreover, healthcare providers should understand the barriers to health behaviors and health-related quality of life to effectively deliver healthcare services.

  • 1. Purpose Rural tourism is made by individuals with different characteristics, needs and wants. It is important to have information on the characteristics and preferences of the consumers of the different types of existing rural accommodation. The stud aims to identify the determinants of consumer preference by type of accommodations. 2. Methodology 2.1 Sample Data were collected from 1000 people by telephone survey with three-stage stratified random sampling in seven metropolitan areas in Korea. Respondents were chosen by sampling internal on telephone book published in 2006. We surveyed from four to ten-thirty 0'clock afternoon so as to systematic sampling considering respondents' life cycle. 2.2 Two-step cluster Analysis Our study is accomplished through the use of a two-step cluster method to classify the accommodation in a reduced number of groups, so that each group constitutes a type. This method had been suggested as appropriate in clustering large data sets with mixed attributes. The method is based on a distance measure that enables data with both continuous and categorical attributes to be clustered. This is derived from a probabilistic model in which the distance between two clusters in equivalent to the decrease in log-likelihood function as a result of merging. 2.3 Multinomial Logit Analysis The estimation of a Multionmial Logit model determines the characteristics of tourist who is most likely to opt for each type of accommodation. The Multinomial Logit model constitutes an appropriate framework to explore and explain choice process where the choice set consists of more than two alternatives. Due to its ease and quick estimation of parameters, the Multinomial Logit model has been used for many empirical studies of choice in tourism. 3. Findings The auto-clustering algorithm indicated that a five-cluster solution was the best model, because it minimized the BIC value and the change in them between adjacent numbers of clusters. The accommodation establishments can be classified into five types: Traditional House, Typical Farmhouse, Farmstay house for group Tour, Log Cabin for Family, and Log Cabin for Individuals. Group 1 (Traditional House) includes mainly the large accommodation establishments, i.e. those with ondoll style room providing meals and one shower room on family tourist, of original construction style house. Group 2 (Typical Farmhouse) encompasses accommodation establishments of Ondoll rooms and each bathroom providing meals. It includes, in other words, the tourist accommodations Known as "rural houses." Group 3 (Farmstay House for Group) has accommodation establishments of Ondoll rooms not providing meals and self cooking facilities, large room size over five persons. Group 4 (Log Cabin for Family) includes mainly the popular accommodation establishments, i.e. those with Ondoll style room with on shower room on family tourist, of western styled log house. While the accommodations in this group are not defined as regards type of construction, the group does include all the original Korean style construction, Finally, group 5 (Log Cabin for Individuals)includes those accommodations that are bedroom western styled wooden house with each bathroom. First Multinomial Logit model is estimated including all the explicative variables considered and taking accommodation group 2 as base alternative. The results show that the variables and the estimated values of the parameters for the model giving the probability of each of the five different types of accommodation available in rural tourism village in Korea, according to the socio-economic and trip related characteristics of the individuals. An initial observation of the analysis reveals that none of variables income, the number of journey, distance, and residential style of house is explicative in the choice of rural accommodation. The age and accompany variables are significant for accommodation establishment of group 1. The education and rural residential experience variables are significant for accommodation establishment of groups 4 and 5. The expenditure and marital status variables are significant for accommodation establishment of group 4. The gender and occupation variable are significant for accommodation establishment of group 3. The loyalty variable is significant for accommodation establishment of groups 3 and 4. The study indicates that significant differences exist among the individuals who choose each type of accommodation at a destination. From this investigation is evident that several profiles of tourists can be attracted by a rural destination according to the types of existing accommodations at this destination. Besides, the tourist profiles may be used as the basis for investment policy and promotion for each type of accommodation, making use in each case of the variables that indicate a greater likelihood of influencing the tourist choice of accommodation.

  • Objectives: This study was designed to investigate the current status of the association of job-related information such as employment status, workplace environment, and hazard material exposures with health examination outcomes. Methods: The study used data from KNHANES 2007-2009 representing the three years of 2007-2009, which was conducted annually using a rolling sampling design that involved a complex, stratified, multistage, probability-cluster survey of a representative sample of the non-institutionalized civilian population in Korea. The final analytical sample consisted of 17,240 participants. Information on age, education, smoking history and alcohol intake was collected during the health interview. Job related information consisted of employment status, workplace environment, and hazardous material exposure. The selected indices of health examination were blood pressure, fasting glucose, blood cholesterol, HDL, SGOT, SGPT, and BUN. Results: In multiple logistic regression analysis using hypertension and pre-hypertension as dependent variables and job related categories as independent variables after covariate adjustments, the odds of hypertension and pre-hypertension were significantly lower in those with responsibility and power in their job activities. Interestingly, low odds for hypertension were observed among those who reported that their jobs were fast-paced. Conclusions: This study confirmed that some job-related categories in employment status, workplace environment, and hazardous material exposure had an association with health outcome status. It is worthwhile to comment that high responsibility and power in job activities were revealed as one of the important favorable factors to improve health condition of workers.
