High price equipment is one of the major factors that increases national health expenditure in developed countries. Computerized Tomography(CT), one of the important high price equipment, has been concerns of health service researchers and policy makers in many countries. In Korea, CT, first introduced in 1984, have spreaded nationwide with rapid speed. Though the Committee for Approving Import of High Price Medical Equipment, founded in 1981, tried to regulate the introduction of high price medical equipment including CT, the effort resulted in failure. The exact situation of diffusion of the high price equipment, however, was not yet investigated. We aimed at the description of the diffusion of CT in Korea and analysis of influencing factors on hospitals for the adoption of CT. We mainly used the database of CT, made in 1996 by the National Federation of Medical Insurance for the purpose of insurance payment for CT. Also characteristics of hospitals were gathered from yearbooks published by the central and local governments and by the Korean Hospital Association. We calculated the cumulative number of the CT per one million population year by year. In turn, multiple linear logistic regression was done to find out the contributing factors for the adoption of CT by each hospital. In the logistic regression model, it is regarded as dependent factor whether a hospital retained CT or not in 1988 and 1993. The major categories of the independent factors were hospital characteristics, environmental factors and competitive conditions of hospitals at the period of the adoption. The results are as follows: Number of CT scanners per one million persons in Korea marked more higher level compared with those of most OECD countries. Major influencing factors on the adoption of CT scanners were hospital characteristics, such as hospital referral level, and competitive condition of hospitals, such as number of CT scanners per 10,000 persons in each district where the hospital was located. In Korea, CT diffused with rather rapid speed, comparable with those of the United States and Japan. The major factors contributing on the adoption of CT for hospitals were competitive condition and hospital characteristics rather than regional health care need for CT. In conclusion, a kind of regulating mechanism would be necessary for the prevention of the indiscreet adoption and inefficient use of high price equipment including CT.

This study examined the factors related to family caregiver satisfaction with institutional care services for beneficiaries under the Public Long-Term Care Insurance(PLTCI) system. Determining what contributes to family caregiver satisfaction is a critical step toward implementing effective quality improvement strategies. A national cross-sectional descriptive survey was conducted from November to December 2008, using proportionate quota sampling based on the location and level of Long-Term Care of the beneficiaries. Total 1,745 family caregivers wrote informed consents and 733 (response rate 42%) completed questionnaires, which included caregiver characteristics, organizational resources, primary objective and subjective stressors, perceived quality of services, and family caregiver satisfaction. Family caregivers were satisfied overall with institutional care. In multiple regression analysis, there was a statistically significant difference in degree of family caregiver satisfaction according to caregiver characteristics(relationship to beneficiary), primary objective stressors (insurance type of beneficiary), perceived quality of services(respect to family caregivers' idea, ADL support, expertness of staff, careful concern of staff, fulfillment of client's requests, and safety of institution's environment). In public long-term care, satisfaction efforts are in an early stage of development. This study is meaningful as the first attempt to measure family caregiver satisfaction with institutional care for beneficiaries under the PLTCI system, and to identify factors affecting the satisfaction. Among the identified factors, the policy makers, the insurer, and the providers need to pay attention to perceived quality of services, in particular, to improve customer satisfaction. Our findings can provide quality care improvement initiatives in the public long-term care setting.

Objectives : This study aims to estimate the oral antihyperglycemic medications adherence among ambulatory care with adult type 2 diabetes patients and to identify factors affecting the medication adherence in Korea. Methods : This study used the Korean National Health Insurance Database. Study population was 40,082 patients who were 20 years of age or older and first diagnosed with type 2 diabetes (ICD-10: E11) in 2004. The patients were followed up for two years in order to measure adherence with oral antihyperglycemic medications. The level of medication adherence was measured by the medication possession ratio (MPR). Results : The average MPR in the study population was 49.5%. The appropriate adherence rate (MPR$\geq$80%) was 29.4% and showed variation according to the characteristics of individual patients. Multiple logistic regression analysis revealed that the odds of appropriate adherence increased with female (OR:1.21, CI:1.14-1.27), older age, increasing ambulatory care visits, health insurance (OR:1.53, CI:1.33-1.76), decreasing ambulatory care providers, using a specialized general hospital as their main attending medical institution (OR:10.08, CI:8.96-11.33), having co-morbidity, using polytherapy (OR:1.07, CI:1.01-1.13). Conclusions : The medications adherence for patient with type 2 diabetes is low in Korea, and shows variation according to the characteristics of patients. For proper management of diabetes, health care policy is expected to be enacted to improve medications adherence continuously. In particular, more intensive management is needed for patients with low medications adherence. Also, health care policy makers need to develop the program to induce health care utilization by a patient to be more concentrated with the same provider.

The information and communications construction business has the characteristics of an infrastructure industry and responsibility for the construction and maintenance of all ICT infrastructures. With the recent proliferation of the smart convergence of various industries based on ICT infrastructure, the role of the information and communications construction business has been highlighted to accommodate the convergence and implementation environment in construction and medical industries. Therefore, this paper seeks policy measures to establish the new role of the information and communications business under the rapidly developing smart convergence environment and the priorities of policy measures to strengthen the capability of the information and communications business using a quantitative model. The analysis result suggests that the difference in importance of each policy measure should be considered in order to execute effectively the policy of promoting the information and communications construction business. Given the constraint of limited budget, policy priorities include the development of new markets, and establishment of incentive for new technology. This study is significant for its theoretical contribution, being the first quantitative approach to policy priorities for the promotion of information and communications construction business under the smart convertgence environment.

The purpose of this study is to determine the direction and significance of variables influencing small and medium enterprises (SMEs) decisions regarding accounting policy in Vietnam. Research data was collected through a survey of 296 subjects, including chief accountants, accountants, managers, and lecturers with practical experience in accounting work at enterprises. With the help of specialized software SPSS, determining the impact of factors on the choice of accounting policy of enterprises is done through a multivariate regression model with control tools Cronbach's alpha determination, EFA factor analysis, and Pearson correlation analysis. Research results show that there are seven factors affecting the choice of accounting policy in Vietnamese SMEs; in which, the factors information technology, legal environment, information demand, manager's awareness, and accounting qualification have a positive impact; and two factors are tax pressure, and financial leverage have a negative impact on accounting policy choice. These results are consistent with most of the previously published studies. However, in contrast to many previous studies, our research shows that accounting's psychological factor does not affect the accounting policy choice. This is consistent with the characteristics of SMEs in Vietnam because the role of accountants is not appreciated in the business.

This study is to compare and analyze the policy decision process between Korea Long-term Care Insurance and Japan's using policy network theory as an analysis tool, and to lead political and theoretical implications. The result of the study is summarized as follows. First, a policy agenda about Long-term Care problem for the Elderly set up by the government-leading both Korea and Japan. and the number of policy participation(actors) increased to characteristics of policy process stage. but there is a difference between Korea and Japan in a background of setting up policy agenda about Long-term Care problem. Second, interaction among policy actors is corporative from early policy agenda establishment stage in Korea and Japan. but it changes to dissenting or critical rapidly as being announced the frame of system to the people. Also, it shows that main policy actors play a role in policy making decision and the connection structures of network is similar to both countries although it has a difference in the interaction frequency. Fourth, although the number of policy actors and the extent of their opinion reflection to the policy effect are different, it shows that policy network pattern is very similar to from policy agenda setting stage to parliament(The National Assemble) policy decision stage as a result of government-leading policy process. The theoretical and political implications of this study are as follows. The number and the variety of policy participation, the importance of establishing opened-interaction system, lots of limitation of policy making-decision process of Japan Long-term Care system, and exclusively the government-leading network has demerits about the reflection of too much government's opinion to the policy outcomes.

Background: Stem cell research competition is accelerating globally since President Obama signed an executive order, repealing Bush-era policy that limited use of federal tax dollars for embryonic stem cell research. Methods: In this paper, we conducted a comparative analysis of stem cell research policy changes in three countries, including the Human Fertilisation Embryology Act (HFEA) of UK, executive order 13,505 (removing barriers to responsible scientific research involving human stem cells) of USA, and Bioethics and Safety Act of South Korea. Debates on stem cell research are based on conflicts of fundamental beliefs that exist in the supporting and opposing coalitions. We compared regional characteristics of the advocacy coalitions in three countries and presented various factors that might be related to the policy changes. Results: The UK government, parliament, and the HFEA have sought expert consultations and public opinions to establish guidelines. UK has made social consensus through continued discussion for a long time. US President's veto power was one strongest factors influencing policy. South Korean policy was influenced by public opinion and policy brokers. Also, South Korea has not made social consensus. UK had a strong leadership and strong adjustment of coalitions but US and South Korea had not. Dr. Hwang's scandal has had one of the greatest impacts on policy decision in South Korea. Conclusion: The power of public opinion was critical in all three countries. In particular, the influence of public opinion was noticeable in South Korea. Also it turned out that in US and South Korea, the presence of a policy broker who could pursue his or her goals was the most powerful factor among the advocacy coalition factors.

This study investigates the influence of policy-related factors on the intention to keep working among mothers with children under 12 years old, especially focusing on the differences between the mothers with preschool children and elementary school children. The study also considers the individual, family, job characteristics of mothers with children, in order to draw the specific impact of policy factors. Data was collected through e-mails from 500 working mothers living in urban area, and 489 interview data were finally utilized in analyses. The results of analyses show that the level of awareness on work-family balancing policy significantly influences on the intention to keep working among mothers with preschool children. On the contrary, there is no statistically significant policy-related factors influencing on the intention to keep working among mothers with elementary school children. Both studies and social polices excessively focused on the mothers with preschool children in terms of work-family balancing issues. Working mothers with elementary school children have not been spot-lighted as beneficiaries from social policy, even though elementary school children also should be cared by others after school. Effective social services assisting work-family balance among mothers with preschool children should be more developed.
