This study estimates the total health expenditure of ambulatory dental care and explores the factors related to disbursements. The study used two waves of a 2008 Korea Health Panel (KHP) survey, of which each wave is composed of 7866 households and 24,659 persons. The KHP includes missing expanses of reimbursement data of the National Health Insurance (NHI), such as out-of-pocket, drugs, and private health insurance. The study estimates total monthly ambulatory dental expenditure and the sub-special categories of dental care. For influential factors analyses, the study exploits log-linear model with age, gender, education, job, equivalence income, the status of chronic diseases, means-tested benefit recipients, private insurance, and the composite deprivation index as independent variables. The total monthly outpatient health spending is estimated to be 102,468 won per household, and for dental, each household spends 31,115 won per month. Older age, means-test recipients, non-regular workers are more likely to spend less money on dental care, whereas private insurers, high income, and those who live in less deprived areas are more likely to spend more money for dental services. From the study we found that the KHP data are more suitable to estimate the total amount of health care markets, especially when the NHI coverage is low, such as for dental care in Korea.

Graduate School of Public Health, Seoul National University The national health insurance system in Korea is characterized as relatively high out-of-pocket payments, which are the principal source of catastrophic health expenditure (CHE). The objectives of this study are to estimate the incidence of household CHE and to clarify the characteristics that affect the occurrence and recurrence of household CHE using the Seoul Welfare Panel Survey database for 2008 and 2010. Thresholds to estimate CHE were 10% and 20% of the total household income (T/X), and 25% and 40% of the income excluding food share (T/Y). Determinants of the occurrence and recurrence of CHE at the threshold of T/X=10% were analysed using multiple logistic regression models. Out of the 3,665 households that responded in 2008 survey, households with CHE were 12.07% (T/X${\geq}$10%), 5.34% (T/X${\geq}$20%), 6.84% (T/Y${\geq}$25%), and 4.44% (T/Y${\geq}$40%). Risk factors associated with household CHE included living with a spouse, non-Medicaid beneficiary, householder unemployment, low household income, the number of disabled members, poor subjective health, and the number of chronic diseases. A total of 41.78% of households with CHE in 2008 repeatedly experienced CHE in 2010. Risk factors of CHE recurrence included decreased household income and an increase in chronic diseases over the two time periods, the number of members with disability or chronic diseases, and the presence of cancer patients in 2008. Households with lower socioeconomic and health status had a higher financial burden on health care than do their counterpart households. There is a need to enhance society-wide financial protection from health spending among vulnerable citizens in Seoul, particularly, households with low income, disabled members or cancer patients.

Although there have been studies regarding the separating policy of dispensary and medical practice, little study have provided a concrete empirical evidence to what extent the policy objectives are achieved. In this paper, we try to provide empirical evidence whether the policy separating dispensary from medical practice achieved the policy objectives, which representatively are reducing the mis-use or over-use of anti-biotic prescriptions and medicines, and decreasing the government spending for the cost of pharmaceutical support. By comparing the average of the rate of change of the number of medicines prescribed, the rate of anti-biotics prescribed, and the government spending for the cost of pharmaceutical support between the areas where the separation policy was implemented and the exceptional areas, we concluded that it is difficult to conclude that the policy separating dispensary and medical practice achieved its policy objects, as it first announced to achieve in the introduction of the policy in 2000. However, the limitation of this study is that the data, that can thoroughly analyze the effect of separating policy of dispensary from medical practice, cannot be collected as expected. Hence, we could not use a parsimonious empirical model to evaluate the effect of the policy introduced in 2000. Rather we used a simple statistical method to extract enough empirical evidence fro m the data available. In the near future, we would expect to see more research that analyze the exact effect of policy separating dispensary and medical practice with concrete empirical model using more sophisticated dataset.

최근 도로, 건물, 지형과 같은 공간정보를 기반으로 한 다양한 융합정보가 생성됨에 따라 이를 효율적으로 표현할 수 있는 지도의 시각화가 중요하다. 그러나 흔히 사용하는 웹 지도 서비스에서 라인, 폴리곤과 같은 복잡한 포인트로 이루어진 형상정보는 지도를 통해 표출하는데 일정 시간이 소요될 뿐만 아니라 이용할 수 있는 사용제한 기준이 있어 정보를 표현하는데 한계가 있다. 이에 본 연구에서는 용량이 비교적 크고 복잡한 공간정보를 효율적으로 가시화하기 위한 기법을 제안하였다. 이 기법은 공간질의하여 일부영역의 데이터만을 가져오고 클라이언트 기반의 움직임 이벤트를 탐지하여 이전 질의 영역을 제외한 정보를 조회하여 확장해가는 방법이다. 이 기법을 적용했을 때 클라이언트가 원하는 영역만의 정보를 요청하기 때문에 표출에 대한 소요시간을 단축할 수 있으며, 불필요한 정보를 가져오지 않아 전체적인 시스템 측면에서도 효율적인 표출이 이루어질 것으로 기대된다.

This study performed an analysis to determine if an individual can maintain the current consumption, in the case of a single retired elderly person's household using the accumulated assets. Assets are divided into three types, based on the behavioral economics life cycle hypothesis : financial assets, real assets excepting residential assets, and residential assets, and it is assumed that these assets were used on a step-by-step basis. Also, if the assets were sufficient, the maximum withdrawal amount was calculated. The results of the analysis are as follows. First, the monetary assets were sufficient to cover the cost of living for 2.7 years, 6.4 years by using the real assets of the non-occupied housing, and 26.3 years in the case of residential property. Second, in the case of preferentially using the financial assets, 4.4% of the sample households were able to cover the cost of living. Households that were not able to cover the cost of living used the next-stage assets, real assets of the non-occupied housing. Households that were not able to cover the cost of living by financial assets liquidated the real assets with the exception of residential assets and used these to cover the cost of living. A total of 4.8% of the households were able to maintain the current cost of living through the second stage and 25.5% supplemented their funds by using residential assets. That is to say, 35% of the sample households were able to maintain the current level of living by using their assets.

촛불혁명으로 집권한 문재인 정부는 사람주도경제를 내걸었다. 이러한 목표를 실현하기 위해 과거 보수정부보다 재정지출 증가율을 높이고 복지비중을 늘리겠다고 약속했다. 이러한 정책 방향은 바람직한 것이긴 하지만 적극적 증세 없이 재정수입 이내에서 최대한 지출하겠다는 것이어서 대규모의 복지확대를 바라는 진보진영의 기대에는 한참 못 미치는 것이다. 현재 우리나라가 당면한 구조적 위기를 극복하기 위해서는 더욱 적극적인 재정정책이필요이다. 당분간은 직접세 위주로 소득 상위 가계와 법인, 고액자산 보유자에 대한 증세를 추진하고 임대소득과세가 잘 정착되도록 노력하면서 국가채무의 증가도 용인하는 방식의 적극적 재정정책을 시행하는 것이 바람직할것이다. 이러한 과제가 잘 마무리되면 다음 단계의 복지확대 및 증세로 나아가는 것이 필요하다.
