Background: The purpose of this study is to evaluate the effect of health insurance coverage expansion for cancer patients on equity in health care utilization and catastrophic expenditure. Methods: To analyze the causal relationship between the policy to expand benefit coverage and the change in health care utilization and out-of-pocket payments of cancer patients, this study employed a difference-in-differences (DID) method. In the DID model, the change in health care utilization, such as health care expenditure, visit days and length of stay, of cancer patients was compared with that of liver disease patients, using Korea Health Panel Data in 2009 and 2010. Results: The policy of reducing cost sharing from 10% to 5% for cancer patients did not have significant effects on equity in health care utilization. The results of this study were different from those of the previous study that showed that the reduction of cost sharing from 20% to 10% significantly improved the equity in health care utilization of cancer patients. In addition, the result of catastrophic expenditures analysis showed the policy did not change the probability of catastrophic expenditures. Conclusion: The results of this study imply that payment for non-covered services account for high out-of-pocket payments, and the reduction in cost sharing for covered services alone may have a limited effect on total financial burden on patients.

This paper examines the performance according to the combination pattern of HRM and business strategy. The business strategy was divided into Miles & Snow's prospector, defender, and analyzer. Data were collected from the Korea Labor Institute's workplace panel survey from 2005 to 2015, and the analysis used 465 companies that are common respondents of the six wave surveys. To test the research model, structural equation modeling was employed. The results of the analysis showed that the combination of high commitment HRM and prospector had a positively significant effect on the performance. Contrariwise, the combination of high commitment HRM and defender, the combination of high commitment HRM and analyzer were not significant effect on performance.

Background: Most developed countries are working to improve their universal health coverage systems. This study investigates regional disparities in unmet healthcare needs and their causes in South Korea. Additionally, it compares the unmet healthcare needs rate in South Korea with that of 33 European countries. Methods: The analysis incorporates information from 13,359 adults aged 19 or older, using data from the Korea Health Panel. The dependent variables encompass the experience of unmet healthcare needs and the three causes of occurrence: "burden of medical expenses," "time constraints," and "lack of care." The primary variable of interest is the region of residence, while control variables encompass 14 socio-demographic, health, and functional characteristics. Multivariable binary logistic regression analysis, accounting for the sampling design, is conducted. Results: The rate of unmet healthcare needs in Korea is 11.7% (95% confidence interval [CI], 11.0%-13.3%), which is approximately 30 times higher than that of Austria (0.4%). The causes of unmet healthcare needs, ranked in descending order, are "lack of care," "time constraints," and "burden of medical expenses." Predictive probabilities for experiencing unmet healthcare needs and each cause differ significantly between regions. For instance, the probability of experiencing unmet healthcare needs due to "lack of care" is approximately 10 times higher in Gangwon-do (13.5%; 95% CI, 13.0%-14.1%) than in Busan (1.3%; 95% CI, 1.3%-1.4%). The probability due to "burden of medical expenses" is approximately 14 times higher in Seoul (4.1%; 95% CI, 3.6%-4.6%) compared to Jeollanam-do (0.3%; 95% CI, 0.2%-0.4%). Conclusion: Amid rapid sociodemographic transitions, South Korea must make significant efforts to alleviate unmet healthcare needs and the associated regional disparities. To effectively achieve this, it is recommended that South Korea involves the National Assembly in healthcare policy-making, while maintaining a centralized financing model and delegating healthcare planning and implementation to regional authorities for their local residents-similar to the approaches of the United Kingdom and France.

This paper estimates relationships between the supply of national highways, measured in lane-km, and the quantity of traffic, measured in vehicle-km traveled. The analysis uses a panel data set of annual observations for the years 1984 to 2003. By using a log-linear lag effect model designed to capture short and long term effects, the paper estimates that national highway vehicle-km traveled has a lane-km elasticity of 0.268 at the country level (Non-Seoul Metropolitan area) and 0.41 at the Seoul metropolitan area for the short term. For the long term, the paper estimates 0.8 for the country level and 1.23 for the Seoul metropolitan area. This paper finds conclusive evidence that increases in highway lane-miles have generated traffic over the period of study, however the increasing ratio of the generated traffic decreases gradually, particularly during the late 1980s.

The purpose of this study is to make practical suggestions to help multicultural adolescents' academic adaptation. For this purpose, changes in the academic adaptation of multicultural adolescents were identified, and longitudinal changes in self-esteem were explored in the relationship between bicultural acceptance attitude and academic adaptation. The data from the panel survey of multicultural youth of the Korea Youth Policy Institute was used for the analysis. The result of analyzing the longitudinal mediating effects of self-esteem between bicultural acceptance and academic adaptation through the multivariate potential growth model, the mediating effects of self-esteem was confirmed. Based on these results, the practical implications for enhancing the bicultural acceptance attitude, academic adaptation, and self-esteem of multicultural youth were presented.

This study used data from the 3rd and 11th year of the Korean Welfare Panel to evaluate the effects of the Long-Term Care Insurance(LTCI) system on the consumption and expenditure of LTCI users' households. The study consisted of program group using LTCI and control group not using. Chi-square and t-test were used for the characteristic differences among the groups, and the difference of consumption expenditure was identified by multiple regression analysis. As a result, LTCI had a statistically significant effect on the health care costs of LTCI users' households, resulting in an increase in health care costs(${\beta}=3.06$). However, there was no statistically significant effect on the total cost of living, basic cost, education cost, and recreation/entertainment cost. Therefore, in order to show the effect of LTC system, we should try to reduce of self-pay and improve the contents and quality of the service of the LTC system.

In recent years, China's Internet finance industry is hot. There is no doubt that Internet finance has been fully integrated into China, forming a new form of financing, and rapidly becoming a new channel for investment and financing in China, shouldering the responsibility of inclusive financing and building China's real economy. However, with investment, there are risks. Based on the panel data of China's Internet financial platform, this paper uses the random effect model to study the influencing factors of Internet financial risks, and draws three conclusions: (1) The user funds and platform funds of the financial platform will be managed separately by the bank, which can effectively reduce the risk of financial transactions on the Internet; (2) The risk of Internet financial transactions can be effectively reduced by avoiding the concentration of platform funds in the hands of a few borrowers through regulatory policies; (3) The liquidity control of funds effectively reduces the risk of Internet financial transactions. Based on the conclusions, we propose optimization strategies for regulatory policies to achieve the healthy and sustainable development of Internet finance.

This study examined the interactive effects between social service use and economic hardship on the family conflicts among low-income families. We analyzed data from about 2,000 low-income families who participated in both the first and the second waves of the Korean Welfare Panel Study using a hierarchical logistic regression model. The main results are as follows. First, take-up rates of social services among low-income families were very low. Second, among the low-income families who did not use any social service, families who experienced more economic hardship were more likely to experience family conflicts. Third, the higher levels of economic hardship increased the positive effects of social service of reducing family conflicts. These findings suggest that the resource for the social services be concentrated on the low-income families who tend to experience more economic hardship and thereby family conflicts and that comprehensive social services be provided in the programs which aim to promote family relationships.

This study sought to clarify the relation of children's suicidal ideation and parental depression/life satisfaction, and the mediating effect of the self-esteem in child. With regard to suicidal ideation in children, most studies have used children's depression as predictor, not parental depression. Similarly, parental life satisfaction have not been included in spite of its general influence on child development. Relations among these variables were examined in 512 children and their parents in $7^{th}$ Korean welfare panel data using the structural equation model. Results showed that the maternal life satisfaction was the only significant factor affecting the suicidal ideation of children, no having the mediating effects of the self-esteem in child. The implication of these results and suggestions for intervention and prevention work, and future research are discussed.

Purpose: This methodological study was conducted to develop and psychometrically test the Transcultural Self-efficacy scale (TCSE-scale) for nurses. Methods: Initial 41 items for the TCSE-scale were generated based on extensive literature reviews and in-depth interviews with 18 nurses who had experience in caring for foreign patients. Cultural Competence and Confidence model was used as a conceptual framework. Content validity was evaluated by an expert panel. Psychometric testing was performed with a convenience sample of 242 nurses recruited from four general hospitals in the Seoul metropolitan area and Gyeonggi-do province of South Korea. To evaluate the reliability of TCSE-scale, a test-retest reliability and an internal consistency reliability were analyzed. Construct validity, concurrent validity, criterion validity, convergent validity and discriminative validity were used to evaluate the validity. Results: The 25-item TCSE-scale was found to have three subscales-Cognitive, Practical, and Affective domain-explaining 91.5% of the total variance. TCSE-scale also demonstrated a concurrent validity with the Cultural Competence Scale. Criterion-related validity was supported by known-group comparison. Reliability analysis showed an acceptable-to-high Cronbach's alpha-.88 in total, and subscales ranged from .76 to .87. The ICC was .90, indicating that the TCSE-scale has internal consistency and stability of reliability. Conclusion: This preliminary evaluation of the psychometric scale properties demonstrated an acceptable validity and reliability. The TCSE-scale is able to contribute to building up empirical and evidence based on data collection regarding the transcultural self-efficacy of clinical nurses. We suggest further testing of the applicability of TCSE-scale in different settings and community contexts.
