Objective: Using the Korean Health Panel data (KHP) of 2008 and 2009, this paper analyzed the effect of antihypertension medication adherence on the changes in medical service utilization and medical expenditure in the next year. Method: Through a face-to-face interview survey, KHP has provided an extensive data on demographic characteristics, medical utilizations behavior, medical expenditure and health behaviors of the targeted households and their members since 2008. KHP is recognized as highly accurate regarding medical expenditure in that it makes the target households to record 'Health diary' whenever they use healthcare service, which could minimize their cognitive bias or memory distortion. The 2010 KHP data was based on the interview from 6,432 households and 19,697 household members. Two part model was used to explore the effects of medication adherence on medical use (logistic regression analysis) and medical expenditures (OLS). Result: Our study result demonstrated that the 74.7% of the patients who strictly adhere to their medication in both years, in 2008 and in 2009, were likely to use inpatient service in 2010. This shows the noncompliant patients were in fact use emergency service less than the compliant patients. Conclusion: Based on our analysis, this paper concludes that the high medication adherence of hypertensive patients could contribute to reduce the emergency service use. Therefore it is highly recommendable for the Korean government and the insurer, NHIS, to actively invest in developing education and promotion program to improve medication adherence among hypertensive patients.

The purpose of this research is to explain what affects the volunteer center's performance on the basis on the program logic model. We assume that internal factors and external factors influence the organizational performance. For the empirical analysis, we use SUR(seemingly unrelated regression). The major findings of this research are as follows: Frist, organizational budget as internal factors are important influential factors. Second, civil society's capacity variable and stakeholder's support variable affect positively volunteer center's performance. Third, the contract out variable's effect as an operation types is not proven statistically. In case of estimating the multi organizational performance, lastly, the SUR method is prefer to the OLS method in the aspect methodology. However, more systemic study is complemented the panel data for organizational performance.

Objectives : The purpose of this study was to estimate the willingness to quit cigarette price among Korean male adults, and to examine the factors affecting the willingness to quit cigarette price. Methods : The data was collected by a random digit dial telephone survey. 702 samples were analyzed by using t-tests, ANOVA and OLS regression analysis. To estimate the willingness to quit cigarette price, smokers were asked dichotomous questions with open-ended follow-up and the starting point of the price was randomized by one of 5 bid prices elicited from a pilot study. Results : The mean of the willingness to quit cigarette price was 4,287 Won per package, which was about 2,000 Won higher than the mean of the actual price the smokers now paid. About 41% of respondents were willing to quit smoking if the price of cigarette would be increased by 3,000 Won, and if the price would be increased by 20,000 Won, all respondents were willing to quit smoking. The factors associated with the willingness to quit cigarette price were the place of residence, the amount of smoking and the degree of exposure to smoking through the mass media. Conclusions : The results showed that to get people to quit smoking, increasing the cigarette price would obviously be effective and much higher prices have a greater effect. Furthermore, to enlarge the effect of increased cigarette prices, providing more cessation programs to small towns, reducing the amount of smoking and decreasing or prohibiting advertisements of cigarettes and smoking in the mass media will be efficient.

The purpose of the study is to review the real situations of the income-gap between urban and rural areas which is focused on as one of the biggest issues revealed in the process of Chinese economic development and to find out which factors will alleviate or deteriorate such income-gap, also to find out such factors will effect differently on the regional characteristics. To analyze it, six factors such as industrialization-ratio, urbanization-ratio, tertiary industry-ratio, the level of both governmental educational support and agricultural support, and Chinese dual-economic structure are considered as explanatory variables, and OLS regression analysis was implemented to the factor data for the period of 1986-2007 about Chinese 31 districts(castles and cities). The results of the analysis show that both industrialization factors and urbanization factors affect significantly to alleviate income-gap between urban and rural areas, and as predicted, they also shows that dual-economic structure between urban and rural areas is the most biggest factors to enlarge the above mentioned income-gap. However, in accordance to the different level of economic development in eastern, central, and western districts the study shows that such factors will affect them differently respectively. The contents are as follows; In eastern district governmental educational support factor will affect the most great influence to alleviate the income-gap, in central district industrialization factor will affect the most great influence to alleviate the gap, and western district governmental agricultural support factor will affect the most great influence to alleviate the gap. Therefore, in solving the issue of income-gap between urban and rural areas in China we recommend that it is necessary for more differential policy in considering regional characteristics than unilateral policy to Chinese whole areas.

The purpose of this study is to examine the impacts of smartphone use on structured social network types in the Korean elderly population. Data was derived from the 2014 survey of living conditions and welfare needs of Korean older persons collected by Korea Institute for Health and Social Affairs. A total of 4,180 participants were selected for the Propensity Score Matching (PSM) analysis. Based on propensity score estimates, the 491 smartphone users (treatment group) and 491 featurephone users (control group) were matched. Ordinary Least Squares (OLS) regression analysis was conducted to examine the relationship between smartphone use and structural social network types. The results showed that among retired older adults, people using smartphone had significantly better structured social networks than those using featurephone even after controlling for covariates. Smartphone users had the higher levels of social contact and social activity. These findings suggested empirical evidence that using smartphone positively affects structured social networks, which might be used as the basis for designing intervention programs to promote social networks and social engagement of retired older adults.

This study examines factors of unemployment and career path challenges commonly faced by youth in the East Coast of Peninsular Malaysia. The study employed a quantitative approach which involved a total of 1,083 youths in Kelantan, Pahang and Terengganu selected at random. Descriptive and multiple regression analysis (OLS) methods were used to analyze demographic distribution of youth in determining factors influencing unemployment among them. The results reveal that the majority of youth respondents in the East Coast states of Malaysia are still unemployed and actively seeking employment. Demographic profiles are based on the survey results, youths seeking employment with 36 per cent distribution in Kelantan, 34 per cent in Pahang, and 30 per cent in Terengganu. Majority of the respondents were youths aged 20 to 24 years with a 40.9 percent percentage. The findings show that there are differences in factors affecting youth unemployment in the three states of East Coast, Malaysia. For Kelantan (age, experience, work mobility, marital status), Pahang (experience, marital status) and Terengganu (experience, gender, marital status, training). This study suggests that youths should be wise in preparing for their career by choosing the right career as well as doing side jobs to gain experience before they pursue for a real job.

This study exemines the roles of corporate social activity (CSR) and executive compensation structure on the pricing of seasoned equity offerings (SEOs) with special focus on the role of CSR in reducing the level of information asymmetry between managers and future shareholders of issuing firms through SEOs. This study also investigates the interaction between executive compensation structure and CSR on the discounting of SEOs. We use a sample of 2,102 seasoned equity offerings of U.S. firms with CSR scores from 1995 to 2015 in our OLS fixed effect regression analysis. The results show that issuing firms with high CSR are more likely to expericence a lower degree of the SEO discount. The results also document a positive association between CSR and a high proportion of equity-based compensation of issuing firms' executives. The findings of this paper confirm that CSR attenuates the impact of information asymmetry and the pre-SEO price uncertainty on the pricing of the offers and hence the SEO discount. Furthermore, CSR reinforces the impact of executive firm-related wealth on the discounting of seasoned equity offerings. It appears that firm-related wealth motivates managers to actively engage in reducing information asymmetry activities before SEOs, thereby decreasing the SEO discount.

This study considered technology commercialization as a sort of external R&D of the licensee firm. Then, this study analyzed industrial characteristics of technology commercialization and interactions between internal R&D and technology commercialization from the licensee's viewpoint. Data from NTIS (National science and Technology Information Service) and KED (Korea Enterprise Database) were matched. 7,645 technology commercializations from 1,980 firms were extracted. Afterward, OLS and quantile regression were applied to the extracted data. The impact of technology commercialization on firm growth was concentrated to few high-tech and medium high-tech firms. Technology commercialization was effective in the growth in a year while internal R&D was effective in the growth in two years. The firm size was insiginificant variable. In analysis of 4 selected industries (automobile, electronics, semiconductor, chemistry), the impact was skewed among industries. Though the importance of technology commercialization is widely acknowledged, quantitative analyses like this study are uncommon. Therefore, this study can be useful for the tailored industry solutions for technology commercialization.

Using data from Korea Welfare Panal Study(KWPS), this study examines the relationship between public income transfers and private income transfers in Korea. This research is analyzed by the procedure of OLS regression analysis. The results are as follows. First, the paper shows that public income transfers crowded out the private income transfers. Specially public assistance crowed out the private income transfers. The amount of public income transfers has negative correlation with the amount of private income transfers. The amount of public assistance income has negative correlation with the amount of private income transfers. But social insurance transfers do not have influence on the private income transfer. Second, the private income transfers in Korea are altruistically motivated.
