Background: As a reform plan of health care system, Accountable Care Organization (ACO) has became an object of attention in the United States after Patient Protection and Affordable Care Act was enacted. ACO is a group of various health care providers and provide coordinated care to its assigned beneficiaries. If ACOs improve the quality level and reduce the cost of care, they can get financial incentives. Under the discussion for a quite long time and demonstration projects, ACO has been established. We aimed to analysis and discuss the history, policy mechanism, contents, status and outcomes of ACO. Also, we intended to suggest political implication Korean health care system with regard to ACO. Methods: We searched the articles related ACO in PubMed and selected several available papers about ACO. Total 56 studies were reviewed and categorized three parts; demonstration projects for formation of ACO, policy mechanism and agenda, empirical results of ACO performance. Results: As a result, establishment of ACO was successful partly in the US. It seems to be due to various project and pilot test for verification in the long time. The empirical effect of ACO was also identified in a few study but it needs more evidences to judge its positive effect. Conclusion: In Korea, there are arguments for the application of ACO. However it is difficult to implement a ACO by different political conditions between Korean and US. Nevertheless ACO proposed us the necessity of paradigm shift in our health policy and could be significant to national policy orientation in the future.

This research analyzed. knowledge structure and its effect factor by analysis of co-author and keyword network in Korea's health policy and administration sector. The data was extracted from 339 articles listed in the Korean Journal of Health Policy and Administration, and was transformed into a co-author and keyword matrix. In this matrix the existence of a link was defined by impact factors which were calculated by the weight value of what the role was and the rate of how many authors contributed. We demonstrated that the research achievement was dependent on the author's status and network index. Analysis methods were neighborhood degree, correspondence analysis, multiple regression and the difference of weight distribution by research fields. Co-author networks were developed as closeness centrality as well as degree centrality by a few high productivity researchers. In particular, power law distribution was discovered in impact factor and research productivity. The effect of the author's role was significant in both the impact factor calculated by the participatory rate and the number of listed articles. Especially, this journal shared its major researchers who had a licensed physician with the Journal of Preventive Medicine and Public Health. Therefore, social scientists were likely to be small co-author network differently from natural scientists. It was so called 'two cultures' phenomenon. This study showed how can we verified academic research structure existed in the unit of journal like as citation networks. The co-author networks in the field of health policy and administration had more differentiated and clustered than preventive medicine and epidemiology fields.

Purpose: This study aims to examine the effect of the copayment reduction policy on the health care utilization of patients under age 15 after the policy started in 2017. (이하는 아래 methodoloty로 이동) Methodology: Data on the ALOS, the average admission cost, and the out-of-pocket expenditure for patients under 15 years of age from 2015 to 2019 were obtained from the National Health Insurance database. Policy effects were measured by analyzing three dependent variables before and after policy: the average length of stay (ALOS), the average admission cost, and the out-of-pocket expenditure for patients under 15 years of age. The collected data were analyzed using the SAS package, and the analysis methods used in this study were the mean difference test and linear regression analysis. Findings: The study results reveal that, after the copayment reduction policy in the year 2017, the ALOS and the out-of-pocket expenditure were significantly decreased, but the average admission cost was significantly increased. Practical Implications: These results imply that the policy of copayment reduction for the patients under the age of 15 has contributed to mitigating the patients' financial burden with little concern about growing medical utilization.

최근 주택 가격이 전국적으로 상승하였고 정부는 실수요자 보호를 위해 금융, 세금 등 다양한 규제를 지역에 따라 시행하였다. 정책 시행 이후 전국적인 주택 가격 평균은 안정되었으나 지역 별로 살펴보면 양극화 현상이 발생하였다. 또한 규제로 인해 오히려 실수요자가 피해를 볼 우려에 대한 논의도 지속되고 있다. 따라서 정책 계획 및 분석에 있어 시장 변수 간의 상관관계 뿐 아니라 미시적으로 시장 참여자들에게 어떻게 정책의 효과가 파급되는 지 분석할 필요성이 있다. 이에 본 연구에서는 변수 간 인과관계로 구성되는 시장 구조 분석을 위한 시스템 다이내믹스와 시장 참여자들의 의사 결정 과정 모델링을 위한 행위자 기반 모델을 통합하여 시뮬레이션 모델을 구축하였다. 개발한 모델에 금융 규제와 세금 규제를 적용하여 주택 가격의 변화와 이에 시장 참여자들이 어떻게 행동하는 지에 대한 분석을 통해 정책의 실효성을 평가하였다. 본 연구를 통해 가격 안정화라는 같은 목적을 가진 두 규제에 대해 시장 참여자들이 다른 의사결정을 함에 따라 시장을 지배하는 피드백의 차이를 확인했다. 이에 따라 정책 대상 지역 뿐 아니라 그 이외의 지역에 대해서도 다른 파급효과가 나타났다.

Background: The study describes the changes resulted from imposition on tertiary hospital outpatient coinsurance rate rise policy and in tertiary or general hospital drug coverage rise policy on healthcare service utilization. Methods: Accordingly, the hypothesis about outpatient healthcare utilization after rise policy in outpatient coinsurance rate and drug coverage was established, using interrupted time-series analysis and segmented regression analysis to test the hypothesis. 5-year analysis period (2007. 3-2012. 3) from the outset year was designated, the data about most common 10 high-ranking of the main diseases targeting visiting patient from age of 6 to 64 were collected. Results: The summary on the major research is followed. First, the medical expense and duration of treatment tends to be increased in case of imposition about rise policy in outpatient coinsurance rate in the tertiary hospital under the interrupted time-series analysis. It showed temporary increase and slow down on account of influenza A even after the policy enforcement. In segmented regression analysis, duration of visit and medical expense in the tertiary hospital increased temporally right after the policy implementation and the decreased rapidly depends on period. Both rise and fall is statistically significant. The second, In case of tertiary or general hospital outpatient drug coverage rise policy, all of the tertiary hospital healthcare service utilization variables by the interrupted time-series analysis, drug coverage policy in the general hospital deeply declined according to decreasing trend before policy implementation. The third, in case of segmented regression analysis, the visit duration and medical expense statistically declined right after the policy implementation in both the tertiary and general hospital. Meanwhile, administration day was statistically meaningful only for the decrease right after the policy implementation. Otherwise, general hospital changes are not statistically meaningful. And the medicine cost was statistically, meaningfully decreased after the increase in drug coverage. Conclusion: Finally, the result demonstrated according to the analysis is only 1 hypothesis is denied, the other 2 are partially supported. Then, tertiary hospital outpatient coinsurance rate increase policy comparatively makes decrease effect on long-term healthcare utilization, and tertiary or general hospital outpatient drug coverage policy showed partially short-term effect is assured.

To find out more efficient ways of implementing health promotion programs and to determine the factors affecting the results of various interventions, we reviewed 73 articles un the effectiveness of health promotion programs. These include the papers on the smoking, alcohol, drug abuse, nutrition(obesity) and stress management etc. Specific interventions evaluated in this review are education based on the lecture or video shows, health-related event activities, modifications of policy or the environment, health risk appraisal etc. By using KIHASA Line of Korea Institute of Health and Social Affairs, National Congress Library Database MEDLINE, we identified 201 articles published from 1980 to Jun. 1979 and finally selected 73 papers which contain the implementation process, and result of each program. The factors used in the analysis of the programs are (1) characteristics of participants (2) interventions evaluated (3) research design (4) length of programs and evacuation point (7) outcome indices (6) effect of program evaluated by each author. The study results did not prove positive effect of education based on lectures or video shows etc. Rather, it was suggested that lecture-based education has negative effect on the result. Event activity such as contest or health festivals has positive effect, and policy change or environmental change is closely related to the event activity. Also, the result shows that the overall effect of programs fur the students is less than that of the programs for the others. The programs conducted over, 1-year are mere likely to have positive outcomes than shorter ones. And, the outcomes of the programs with controlled research design such as experimental or quasi-experimental study tend to be evaluated inferiorly to those with non-experimental design.

The Livestock Raw Material Purchase Fund is a policy to increase the export of livestock products by providing loans to exporters of livestock products (including byproducts). The policy started in 2015 and the annual budget is about 26 billion won. However, a quantitative evaluation of policy effects has not yet been made. Therefore, in this study, the economic surplus of the policy was analyzed using the equilibrium displacement model (EDM). From the results of the welfare analysis, from 2016 to 2019, producer surplus in the chicken and duck market increased by KRW 70.9 billion, while consumer surplus decreased by KRW 70 billion. In other words, the total economic surplus of the chicken and duck market increased by about one billion won during the same period due to the increase in export demand according to the policy. Therefore, the Livestock Raw Material Purchase Fund can be viewed as a policy to maintain and increase export demand for export livestock products and to improve the economic surplus of the livestock product market. Also, since the policy is based on loans, it does not place a burden on the government's finances. Therefore, this policy should continue in the future.
