Purposes: There exist many non-covered services that the National Health Insurance does not cover, and thus, their prices are set by individual health care providers. However, little study has been done to investigate how hospitals set prices for those services. The purpose of this study is to examine the relationship between ownership, profitability, and prices of those services for a sample of general hospitals. Methodology/Approach: Data regarding the prices of major non-covered services (e.g., upper-level hospital room fees, MRI, Da 7inci robot surgery, and LASIK) were obtained from the Health Insurance Review and Assessment Service and the financial information, as well as other characteristics, were derived from the financial reports from the Korea Health Industry Development Institute. Descriptive statistics, t-tests, and multiple linear regression analyses were used to test the relationship between the independent variables and the dependent variables. Findings: Hospitals owned by private universities appeared to have higher prices for non-covered services while regional public hospitals tend to have lower prices. Profitability, measured by operating margin, was not significantly related to the prices. Hospitals that charge higher prices were more likely to be located in the capital area (Seoul, Incheon, and Gyeonggi), and to employ larger number of personnel. Practical Implications: Public hospitals tend to charge lower prices for non-covered services. Relative market power appears to be related to pricing. Further research is needed to investigate whether such a relationship varies over time and its effects on the quality and access.

Jeungsan(甑山) carried out the Universal Redesign(天地公事) through which the former world full of a mutual opposition(相克) can be peacefully transferred into the latter world composed of a mutual beneficence(相生). Although the Universal Redesign consists of such three factors heaven, earth, and human, it converges towards Human Redesign in that humans are the main agents for heaven and earth. Human as Redesign object is characterized as a member of community, not an anarchistic individual. The Universal Resign of Jeungsan is eventually connected with the construction of a country comprising a mutual beneficence in that it is the most typical strain among all the human communities. His Universal Resign for foundering the foremost country does not target all the countries, but only one country upon and through which the world with a mutual beneficence can be formed. He executed the Universal Redesign based on such three principles as Haewon sangsaeng(解冤相生), Boeunsangsaeng(報恩相生), and Wonsibanbon(原始返本), Judging from such principles, Korea can be naturally selected as the target of the Universal Redesign for constructing the foremost country. It is approaching when the Universal Redesign in order to transform Korea into the foremost country comes true. The first step for Korea to be made as the foremost country is the construction of DMZ World Peace Park (DWPP) which was proposed by Bak Geunhye, the Korean President, to Obama, the President of USA, in 2013 she visited there. DWPP can be expected to be a center for corporation and interchange between South and North Korea under the interest and support of the world including UN, furthermore, the Capital area of reunified Korea, and finally the world hub of inter national political and economic relation. DWPP is planned to be built at the core of the best place in Korea which is a propitious spot all over the world, upon which a new world capitalism order armed with mutual beneficence can spread.

거시경제변수들 간의 영향관계에 대한 논의는 매우 중요한 연구주제로 자리잡고 있다. 자본자유화와 관련하여 가장 많이 논의되는 경제변수들은 환율과 주가이며, 이 두 변수들은 상호영향관계를 가지는 것으로 파악되고 있다. 그러나 변수의 관찰빈도와 관찰기간에 따라 그 결과는 다르게 나타나고 있다. 본 연구의 목적은 관찰빈도와 관찰기간에 따라 변수의 영향관계가 달라지는 것으로 나타날 경우 기존 연구들이 제시하고 있는 분석 결과의 불일치에 대한 원인을 설명함과 동시에 신뢰성 있는 연구결과의 제시 방법을 논의하는 것이다. 본 연구에서도 관찰빈도와 관찰기간을 달리했을 때, 환율과 주가에 대한 VAR 분석 결과가 다르게 나타남을 볼 수 있었다. 따라서 환율과 주가에 관한 연구를 수행함에 있어서 보다 신뢰성있는 연구결과를 도출하기 위한 적절한 관찰빈도와 관찰기간의 적정수준을 제시하기 위하여 몬테칼로 시뮬레이션을 이용하였다. 몬테칼로 시뮬레이션 결과 추정된 각 계수값의 95% 신뢰구간에 실제 VAR모형 분석과정에서 도출된 계수값이 포함될 비율은 관찰 빈도가 높을수록(예를 들어 일별 혹은 주별), 관찰 기간에 있어서 짧은 기간보다 보다 더 긴 기간을 적용할 때 더 설명력이 높다는 기존의 연구결과를 지지하는 것으로 나타났다.

본 논문에서는 1996~2008년 기간 동안 생존분석을 이용하여 외국인투자자의 중국상업은행 투자결정요인에 관하여 검증하였다. 실증분석 결과, 첫째, 기업규모가 클수록, 유동성비율, 비이자수익비율이 낮을수록 외국자본이 유입될 가능성이 보다 높음을 발견하였다. 이는 중국 은행시장의 개방과 함께 중국상업은행의 지분을 매입한 외국인투자자는 규모는 크지만 재무상태가 악화된 중국상업은행에 주로 투자했음을 시사한다. 둘째, 주식제상업은행의 경우 외국인투자자는 자산의 건전성이 취약하고 비이자수익이 낮은 은행의 지분을 매입한 반면, 도시상업은행의 경우 규모가 크고, 유동성이 낮은 은행의 지분을 주로 매입하였다. 이러한 결과는 하나의 도시를 기반으로 하는 도시상업은행에 대한 투자에 있어, 외국인투자자는 최소한의 규모 이상을 가진 중국상업은행을 지분매입 대상으로 삼아 해당 지역에서 시장지배력을 확대하려는 동기를 가진 것으로 해석된다.

This research tries to review the history and concepts of Thai temple mural painting. According to the research results, the history of Thai mural painting dates back to the late 14th century when Wat Chedi Chet Taeo in Si Satchanalai was built. The Sinhalese elements embedded in the Sukhothai murals are also found in the Ayuthayan stupa murals made in the early 15th century. The mid 18th century's Burmese invasion into Ayuthaya destroyed most of Buddhist temples in the Kingdom of Ayuthaya and as a result, Buddhist murals of the late Ayuthayan age are hardly found except for some temple murals located outside of the capital. The late Ayuthayan murals are much different from the early Ayuthayan murals in that they are narrative in depicting Jataka and the life of Lord Buddha. This classical mural painting culminated in the age of Rama III of Bangkok Dynasty. His successor Rama IV undertook westernized reforms which influenced the area of traditional mural painting. Consequently, new western style Buddhist mural paintings were produced while themes of mural painting were enlarged to the other subjects such as historical recording of royal and social events. This trend continued in the age of Rama V but the development of Thai Buddhist mural painting discontinued after the death of Rama V due to the rapid westernization and decrease of illiteracy. The existing Buddhist murals produced on or before the reign of Rama V are deteriorating and disappearing. The reasons for this are partly because of Thailand's humid climate. However, some social backgrounds such as the lack of concern for preserving old Buddhist murals can not be disregarded. Considering the substantial value of Thai Buddhist murals as a cultural resource in Thai society, it is very urgent to establish appropriate conservation policy for them.

Objectives: The high readmission rate of patients with chronic obstructive pulmonary disease (COPD) has led to the worldwide establishment of proactive measures for identifying and mitigating readmissions. This study aimed to identify factors associated with readmission, as well as groups particularly vulnerable to readmission that require transitional care services. Methods: To apply transitional care services that are compatible with Korea's circumstances, targeted groups that are particularly vulnerable to readmission should be identified. Therefore, using the National Health Insurance Service's Senior Cohort database, we analyzed data from 4874 patients who were first hospitalized with COPD from 2009 to 2019 to define and analyze readmissions within 30 days after discharge. Logistic regression analysis was performed to determine factors correlated with readmission within 30 days. Results: The likelihood of readmission was associated with older age (for individuals in their 80s vs. those in their 50s: odds ratio [OR], 1.59; 95% confidence interval [CI], 1.19 to 2.12), medical insurance type (for workplace subscribers vs. local subscribers: OR, 0.84; 95% CI, 0.72 to 0.99), type of hospital (those with 300 beds or more vs. fewer beds: OR, 0.77; 95% CI, 0.66 to 0.90), and healthcare organization location (provincial areas vs. the capital area: OR, 1.66; 95% CI, 1.14 to 2.41). Conclusions: Older patients, patients holding a local subscriber insurance qualification, individuals admitted to hospitals with fewer than 300 beds, and those admitted to provincial hospitals are suggested to be higher-priority for transitional care services.

The objective of this study is to examine how to maximize the efficiency of hospital management by minimizing the unit cost of hospital operation. For this purpose, this paper proposes to develop a model of the profit maximization based on the cost minimization dictum using the statistical tools of arriving at the maximum likelihood values. The preliminary survey data are collected from the annual statistics and their analyses published by Korea Health Industry Development Institute and Korean Hospital Association. The maximum likelihood value statistical analyses are conducted from the information on the cost (function) of each of 36 hospitals selected by the random stratified sampling method according to the size and location (urban or rural) of hospitals. We believe that, although the size of sample is relatively small, because of the sampling method used and the high response rate, the power of estimation of the results of the statistical analyses of the sample hospitals is acceptable. The conceptual framework of analyses is adopted from the various models of the determinants of hospital costs used by the previous studies. According to this framework, the study postulates that the unit cost of hospital operation is determined by the size, scope of service, technology (production function) as measured by capacity utilization, labor capital ratio and labor input-mix variables, and by exogeneous variables. The variables to represent the above cost determinants are selected by using the step-wise regression so that only the statistically significant variables may be utilized in analyzing how these variables impact on the hospital unit cost. The results of the analyses show that the models of hospital cost determinants adopted are well chosen. The various models analyzed have the (goodness of fit) overall determination (R2) which all turned out to be significant, regardless of the variables put in to represent the cost determinants. Specifically, the size and scope of service, no matter how it is measured, i. e., number of admissions per bed, number of ambulatory visits per bed, adjusted inpatient days and adjusted outpatients, have overall effects of reducing the hospital unit costs as measured by the cost per admission, per inpatient day, or office visit implying the existence of the economy of scale in the hospital operation. Thirdly, the technology used in operating a hospital has turned out to have its ramifications on the hospital unit cost similar to those postulated in the static theory of the firm. For example, the capacity utilization as represented by the inpatient days per employee tuned out to have statistically significant negative impacts on the unit cost of hospital operation, while payroll expenses per inpatient cost has a positive effect. The input-mix of hospital operation, as represented by the ratio of the number of doctor, nurse or medical staff per general employee, supports the known thesis that the specialized manpower costs more than the general employees. The labor/capital ratio as represented by the employees per 100 beds is shown to have a positive effect on the cost as expected. As for the exogeneous variable's impacts on the cost, when this variable is represented by the percent of urban 100 population at the location where the hospital is located, the regression analysis shows that the hospitals located in the urban area have a higher cost than those in the rural area. Finally, the case study of the sample hospitals offers a specific information to hospital administrators about how they share in terms of the cost they are incurring in comparison to other hospitals. For example, if his/her hospital is of small size and located in a city, he/she can compare the various costs of his/her hospital operation with those of other similar hospitals. Therefore, he/she may be able to find the reasons why the cost of his/her hospital operation has a higher or lower cost than other similar hospitals in what factors of the hospital cost determinants.
