Unmet healthcare needs are being used as an important indicator of the accessibility of healthcare services worldwide. To examine current status and trends of unmet needs in Korea, we used data from four sources: the Korea National Health and Nutrition Examination Survey (KNHANES, 2007-2017); the Community Health Survey (CHS 2008-2017); the Korea Health Panel Survey (KHP 2011-2015); and the Korean Welfare Panel Study (KOWEPS 2006-2017). The proportion of individual reporting unmet healthcare needs as of 2017 was 8.8% (KNHANES), 10.6% (CHS), and 12.4% (KHP as of 2015). The proportion of households reporting unmet healthcare needs due to cost was 0.5% (KOWEPS). Annual percentage change was -19.2%, -13.3%, -5.8%, and -13.3% respectively. Low income populations had more unmet healthcare needs than high income populations. However, unlike the last two studies, the main reason for unmet medical reasons was that there was no time regardless of income level.

This study analyzed factors influencing cultivation area of two major apple cultivars, Fuji and Hongro, applying the panel SUR model to survey data from farms. Characteristics of farms, distribution factors, and weather factors were the independent variables of the model. The analysis indicated that characteristics of farms, distribution factors, and weather factors influence the cultivation area of Hongro and Fuji. The independent variables were also found to have different levels of influence on increase and decrease of the cultivated area. Helping predict changes in cultivation area of Hongro and Fuji, the research results can be used as primary data to support efforts to prevent price fluctuations due to changes in supply.

Purpose: The aim of this study was to examine the correlation between school-life adjustment and suicidal ideation in adolescents by applying the latent growth curve models to the longitudinal data. Methods: This study analyzed three waves of data from the Korean Children & Youth Panel Survey (2014~2016). A total of 1,534 students were included in the analysis. In the application of the latent growth curve models to the longitudinal survey data, we analyzed the initial status and growth changes for each wave, identified individual differences in the general characteristics, and examined the direct relationship between the two latent constructs. Results: The analysis revealed that variations in the initial status and rate of school-life adjustment were significant with respect to parents' education level, household income and academic satisfaction. Variations in the initial status and growth rate of suicidal ideation were significantly associated with household income and family structure. The relationship between school-life adjustment and suicidal ideation showed a negative correlation in which the starting value of the former increased and that of the latter decreased and vice versa. Conclusion: The results confirmed that school-life adjustment and suicidal ideation varied according to students' general characteristics. In addition, school-life adjustment was negatively correlated with suicidal ideation, thereby highlighting students' ability to adjust as an important factor influencing their suicidal thinking.

Purpose: The purpose of this study is to empirically evaluate the unintended welfare losses induced by paid sick leave, examine the severity of the unintended moral hazard loss caused by paid sick leave, and evaluate how much moral hazard cost society can accept to obtain paid sick leave benefits. Research Design, Data and Methodology: We examine the Medical Expenditure Panel Survey data collected in 2013 and 2014 by employing a panel probit analysis to control for individual heterogeneity. Results: The estimation result shows that the probability of absence due to paid sick leave increases from 4.91% to 7.84%. Among them, excluding the probability of increasing absence from 1.29% to 2.69% due to the actual disease, the probability of absence due to the moral hazard was estimated to be 2.41% to 6.49% in the proposed models. Based on the result, if we evaluate the increase in absence caused by moral hazard as a social cost, the estimated cost is approximately $174 to $297 per worker per year. Conclusion: Considering these expected costs, our society can obtain the access benefit from paid sick leave if we are willing to accept the moral hazard cost.

Data from Panel Survey of Employment for the Disabled(4th year, 187 workers) was used for analyzing the difference between hearing aid users and nonusers for their job satisfaction and daily life satisfaction. The analyses result shows that there are no significant differences in both job satisfaction and daily life satisfaction between hearing aid users and nonusers. However, job satisfaction of hearing aid users has a positive role in daily life satisfaction. Although hearing aids to the hearing impaired played very important role, it was thought to be resulted that some influence factors such as the increase of using IT devices and the expansion of communication support services weren't applied because of the nature of the panel data. These limitations of the study and implications are presented at the conclusion.

Objectives: This study aimed to verify the impact of dental health care insurance coverage policy by analyzing the changes in dental care utilization and expenditures over 5 years from 2012 to 2016, when the dental health insurance coverage expansion policy was implemented. From the national cohort data collected by the Korea Health Panel Survey, a retrospective study was conducted for all household members using dental services. Methods: This study statistically verified the difference in the dependent variables by frequency analysis, chi-square test, t-test, and one-way analysis of variance (SPSS version 22, IBM Co. USA, p<0.05). Results: The annual utilization rate steadily increased from 23.4% to 26.1% between 2012 and 2016. Although there were differences in utilization rates by gender, age, and income level, patients kept using the dental services in 2016 regardless of the type of health insurance. The average annual copayment for patient expenditures (out-of-pocket amount) increased from ￦463,844 to ￦537,401 in 2012 and 2016, respectively. Of the dental care expenditures over 5 years, the ratio of uninsured expenses by the elderly decreased from 38.5% to 25.9%, and the national health insurance service coverage increased from 40.3% to 49.1%. Conclusions: Although this policy did not reduce overall patient expenditures, it has been found that there was a positive effect on the elderly and low-income groups; it increased the utilization and access to dental services.

This study examined the onset of adolescent delinquency through discrete-time survival analysis. Our analysis used data obtained from the Korean Children & Youth Panel Survey, and included 2,277 middle school students. The main analysis results are as follows. First, the hazard probability for the occurrence of delinquency was the highest at 16.6% in the second year of middle school, slightly decreased in the third year of middle school, but continued to increase as the overall grade increased. Second, adolescent psychological and emotional factors have significantly affected the onset of delinquency. Third, negative parenting methods had a significant impact on delinquency, but neglect was not significant. Fourth, having delinquent friends was an important factor affecting the status of delinquency. Fifth, among the school factors, adjustment of learning activities, adjustment of school rules, and adjustment of friendship relations influenced the status of delinquency, while the adjustment of teacher relations was not significant. As early intervention is important to prevent juvenile delinquency, education and support for establishing healthy relationships are needed.

Background: Population aging is a serious problem in Korea. And we have experienced a rapid increase in the health expenditures of the elderly. The purpose of this paper is to analyze the effect of having a usual source of care (USC) for the elderly. Methods: This study used the Korea Health Panel Survey data of 2012, 2013, 2016, 2017, and 2018. The sample was the person who answered the USC questions among the elderly. The panel logit model was used to analyze the determinants of having USC and the panel simultaneous equation model was used to analyze the effect of having USC among the elderly on the medical expenses, medical utilization, and subjective health status. Results: The estimation result shows that age, income, marriage, and so forth turn out to be the factors of having USC. Having the clinic level USC is estimated to reduce the health care utilization and the health expenditure and to improve the subjective health status. Conclusion: It is expected that the result of our analysis will provide evidence for encouraging having USC.

Suicide is becoming a public health issue in many countries, and even more so in Korea. Korea has the highest suicide rate in the Organization for Economic Cooperation and Development countries. To address these issues, we investigated the recent trends in suicidal ideation and suicide attempts among the adult population. We used data from four sources: Korean National Health and Nutrition Examination Survey (KNHANES, '2007-2012, '2013, '2015), Korean Community Health Survey (KCHS, '2008-2009, '2013), Korean Wealth Panel Study (KOWEPS, '2012-2015), and Korea Health Panel Survey (KHP, '2010-2013). Weighted frequencies and trend tests were used. The rate of suicidal ideation as recent year was 5.10% (KNHANES, '2015), 8.95% (KCHS, '2013), 2.34% (KOWEPS, '2015), or 5.39% (KHP, '2013). Regarding the suicide attempts, the rate of suicide attempts as recent year was 0.61% (KNHANES, '2015), 0.41% (KCHS, '2013), or 0.04% (KOWEPS, '2015). Average percent change of suicidal ideation during survey year was -2.80% (KNHANES, '2007-2012), 5.78% (KNHANES, '2013-2015), 0.62% (KCHS, '2008-2013), -5.63% (KOWEPS, '2012-2015), and -10.94% (KHP, '2010-2013). Average percent change of suicide attempts during survey year was -3.84% (KNHANES, '2007-2012), 4.55% (KNHANES, '2013-2015), -2.54% (KCHS, '2008-2013), and -18.96% (KOWEPS, '2012-2015). Those who had lower income level were more likely to have self-reported suicidal ideation and suicide attempts. Our results suggest that further efforts are needed for more effective intervention to identify and manage low income strata with suicide problem.
