The ordinary least square estimator of the disturbance variance in the pooled cross-sectional and time series regression model is shown to be asymptotically unbiased without any restrictions on the regressor matrix when the disturbances follow an equicorrelated error component models.

Health promotion policies have needed to assess in detailed and evidence-based work to set a policy goal and clear future directions of health promotion in Korea. To identify the major factors related with health promotion, we assessed the associations between public health outcome (potential years of life loss, PYLL) and national health determinants. For this purpose, we used a pooled cross sectional time-series regression analysis with corrected fixed effect models involving sixteen member countries of the Organisation for Economic Cooperation and Development during the period 1970 to 2001. The PYLL was positively associated with tobacco and alcohol consumption (model 1 and 2) and calories intake (model 2 and 3) while the PYLL was negatively associated with GDP, fruit and vegetable intake (model 2), number of doctors (model 3), coverage rates of health care security, and elderly population rates (model 4). In conclusion, health behaviors related with tobacco, alcohol, and nutrition were significant health determinants for health outcome. Overall analysis results of this study will provide a guidance toward improved macro- and micro-policy development for future health promotion policy in Korea.

본 연구의 목적은, 우리나라 광역 지방자치단체를 중심으로, 지역간 빈곤의 실태를 비교하고, 지역의 경제 사회적 특성에 기초한 요인을 분석하는데 있다. 이를 위해 1998년부터 2006년까지 제주도를 제외한 15개 광역 시 도의 빈곤율을 한국노동패널자료를 활용하여 측정하고, 각 지역의 정치, 경제, 인구구조, 고용, 산업구조, 재정 측면의 다양한 변수를 포함하여 결합회귀분석을 실시하였다. 분석의 결과, 우리나라 절대적 빈곤율의 평균 수치는 13.19%이고, 상대적 빈곤율은 15.50%이며, 최근 들어 두가지 지표 모두 악화되는 경향을 보이고 있다. 그리고 강원도와 충청남도의 빈곤 수준이 상대적으로 높게 나타나며, 서울특별시와 울산광역시에서 낮게 나타나고 있다. 또한 높은 수준의 재정자립도, 사회복지비 지출 수준, 상용직 비율과 제조업 종사자 비율 등이 지역의 빈곤율을 감소하는데 긍정적인 역할을 하는 것으로 밝혀졌다. 본 연구는 기존의 사람에 기반(people-based)한 반빈곤 정책의 효과성을 높이기 위해서는 지역에 기반(place-based)한 다양한 정책적 모색이 필요하다는 사실을 제언하였다.

The purpose of this study is to analyze the determinants of social welfare expenditure in local government. The period of 1995 through 1998 data in Seoul, 6 other metropolitan areas, and 9 provinces (Do) were selected and pooled as unit of analysis and total 8 independent variables were selected based on the theoretical background and previous studies. The pooled cross-sectional time-series regression using SPSS program was adapted for the analysis. Among selected independent variables, the rate of economic expenditure to the local government expenditure, the rate of financial self-reliance, and the increase rate of social welfare expenditure to the previous year has been played a significant role in the rate of social welfare expenditure to the total expenditure. Both the rate of economic expenditure and rate of financial self-reliance have had a negative impacts on the rate of social welfare expenditure and the increase rate of social welfare expenditure have affected the rate of social welfare expenditure positively. Therefore, the variables based on the economic constraint theory as well as incrementalism perspective gives greater explanatory power of the social welfare expenditure than the variables on the political choice theory in Korean local government.

The Objective of this study was to design the model which predict the future cash flow of hospitals and on the basis of designed model to support sound hospital management by the prediction of future cash flow. The five cash flow measurement variables discussed in financial accrual part were used as variables and these variables were defined as NI, NIDPR, CFO, CFAI, CC. To measure the cash flow B/S related variables, P/L related variables and financial ratio related variables were utilized in this study. To measure cash flow models were designed and to estimate the prediction ability of five cash flow models, the martingale model and the market model were utilized. To estimate relative prediction outcome of cash flow prediction model and simple market model, MAE and MER were used to compare and analyze relative prediction ability of the cash flow model and the market model and to prove superiority of the model of the cash flow prediction model, 32 Regional Public Hospital's cross-section data and 4 year time series data were combined and pooled cross-sectional time series regression model was used for GLS-analysis. To analyze this data, Firstly, each cash flow prediction model, martingale model and market model were made and MAE and MER were estimated. Secondly difference-test was conducted to find the difference between MAE and MER of cash flow prediction model. Thirdly after ranking by size the prediction of cash flow model, martingale model and market model, Friedman-test was evaluated to find prediction ability. The results of this study were as follows: when t-test was conducted to find prediction ability among each model, the error of prediction of cash flow model was smaller than that of martingale and market model, and the difference of prediction error cash flow was significant, so cash flow model was analyzed as excellent compare with other models. This research results can be considered conductive in that present the suitable prediction model of future cash flow to the hospital. This research can provide valuable information in policy-making of hospital's policy decision. This research provide effects as follows; (1) the research is useful to estimate the benefit of hospital, solvency and capital supply ability for substitution of fixed equipment. (2) the research is useful to estimate hospital's liqudity, solvency and financial ability. (3) the research is useful to estimate evaluation ability in hospital management. Furthermore, the research should be continued by sampling all hospitals and constructed advanced cash flow model in dimension, established type and continued by studying unified model which is related each cash flow model.
