This study attempts to assess the effect of the 1st class health insurance program to the income redistribution among the participants in a unit health insurance cooperative. One health insurance cooperative, located in Seoul, with 1558 members and 768 households was selected for this purpose. The relationships between amount of premium payed and benefits from the cooperative were compared. Necessary data were obtained from the bills submitted to the health insurance cooperative by the contracted medical institutions from 1st January 1977 to 30th June 1979. Households and individuals were the unit of the assessment. The indicators measuring income redistribution effect were the ratios between the benefit and expected benefit and the ratios between the benefit and the mean benefit. The major findings were: 1. The ratios between the benefits and the expected benefits were lower than 1 in the high income group and greater than 1 in the middle and lower income groups. This fact imply that the income redistribution effect was shown in the studied groups. It was shown that the middle income group received the greatest benefit, and then the lower income group. 2. The ratios between the benefit ana the mean benefit of the households in the higher standard income grade, were found to be higher. This means that the equity of the benefits of households were not achieved by the policy of the health insurance plan. 3. The health insurance utilization rates of the higher standard income group, measured by the household unit, were higher, and by the individual unit, the same rates of the middle income group were higher than other groups.

This study is conducted to propose urban park utilization and master plan in rural areas. Urban parks designed for the rural areas can be divided into three types: a themed type for rural tourism, a community type for hub regenerations and a waterfront type for using agricultural reservoirs. To use the themes and characteristics of ruralness, these types are required a multi-layered spatial structure. And ecological, cultural and economic networks of local tourism resources have to be integrated by utilizing agricultural reservoirs. Therefore, urban parks in rural areas can be defined as a part of the public benefit project aiming to revitalize the local economy. Also, urban parks are necessary to use attractions and amenities in rural areas. Based on theoretical backgrounds, this study proposed two sustainable master plans as the tourism resource development project for Baelyeonje, Gulye-gun. For ecological and cultural sustainability, this study proposed the environment restoration plan which reinforces the scenic resource of Nogodan in Mt. Jiri by developing the underdevelopment plan with consideration of the local landscape characteristics and resources. For economic sustainability, building the Mt. Jiri tourism complex and economic communities are needed to promote investments for securing mutual economic benefits. To achieve the sustainability, further studies related to the social equity and investment of private capital in rural areas are needed.

Hydro-electric power generation from multi-purpose dams has been playing important roles in the electric power supply network in Korea. Although the total share of hydro power in national electricity supply now becomes very small, the peak-shaving and frequency control capability of hydro power helps the power company enormously in maintaining the quality of power. But since the company that builds and operates the multi-purpose dams in Korea has to sell all the electricity produced to the monopolistic utility, there have been various problems in justifying the investment, designing pricing mechanism, and controlling operations of the power plants. In addition, economic evaluation of the hydro power has been distorted by a variety of reasons and hence it has been very difficult to encourage effective development and utilization of national water resources. To make the problem worse, both parties are public companies with X-inefficiency problems. Thus, changing environment requires to reengineer the system that governs hydro power generation. We address the problems of Korean hydro-electric power generation system in four areas: the investment justification process, the operations decison right of the hydro power plants, the pricing of the purchased-power, and the negotiation of contract revision. Then we propose improvement directions of new hydro-electric power system in view of static and dynamic efficiency, X-inefficiency and equity.

This research was performed to investigate the characteristics and determination factors on tertiary hospital inpatients. The used data was the four waves of Korea Health Panel(2008, 2009, 2010, 2011), and the number of subjects was 4,430 cases of tertiary and general hospital admission. The statistical methodology used in the study is the logistic regression model. The significant affecting factors in utilizing tertiary hospital admission were gender, marital status, education, household income, residence region and ICD-10 classification. Man, graduating college/university, married, high-income were socio-economic affecting factors in tertiary hospital admission. Medical need factor of ICD-10 classification and residence region of inpatients was also significant affecting factors in tertiary hospital admission. The 81.4% of inpatients at tertiary hospital had chronic disease and the 12.9% of inpatients readmitted, the 68.2% had a selecting doctor and the only 26.7% of inpatients reinforced by private medical insurance. This study recommended the Korean government to provide proper rule for tertiary hospital admission in order to improve the equity and efficiency of health care system.

This paper aims at overviewing Korean fisheries profile with a view on why Korean fisheries need marine ranching program as a new fisheries paradigm - a community-based co-management approach and drawing some policy implications from the advanced experience in fisheries. The aims of community-based co-management approach as a planned approach can be set out under the planning objectives of efficiency and equity. In this context Tongyeong marine ranching program is an important government-sponsored pilot enterprise. Experiences in the advanced fisheries such as Canadian Snow-Crab case suggest that in order to be successful for marine ranching be successful it is necessary that (i) there should be high-value species, (ii) property right should be established, (iii) there should be the reasonable number of participants involved, (iv) the participants and the government should be able to share resource enhancement/management/utilization responsibilities and associated fisheries management expenses. Among these, management cost sharing based on the practical partnership between fishing communities and government is of particular importance because the government must have a full responsibility for all ranching program expenditure unless revenues sufficient to guarantee reasonable income and to share management cost are generated from the ranching business.

Although the diffusion of mobile services appears to be occurring much more rapidly than the spread of wired services, there are risks of a new type of digital divide: the mobile divide. The mobile divide, which refers to a specific digital divide that involves the unbalanced diffusion of mobile technologies, must be concretely studied. Thus, this study focuses on the mobile divide with respect to disadvantaged populations. Although various studies suggest that the diffusion of mobile devices may reduce the digital divide, somestudies argue against the positive effect of mobile devices in addressing traditional digital devices. Low and O'Connell (2006) insisted that equity of access to mobile technologies should be considered in the contextof the traditional digital divide; they argued that there may be socio-economic barriers to accessing mobile devices and the mobile Internet that are similar to the socio-economic barriers to accessing stationary computers and the stationary use of the Internet. Focusing on the smartphone divide, this study suggests that emphasizing utilization is an appropriate manner in which to bridge the mobile divide rather than focusing on other factors, such as accessibility and capability, thatprevious studies have used to measure the traditional digital divide.

In the competitive electricity market, various pricing methods are developed and practiced in many countries. Among these pricing methods, marginal loss factor(MLF) can be applied to reflect the marginal cost of network losses. For the calculation of MLF, power flow method has been used to calculate system loss deviation. However, this power flow method shows some shortcomings such as necessity of regional reference node, and absence of an ability to consider network constraints like line congestion, voltage limit, and generation output limit. The former defect might affects adversely to the equity of market participants and the latter might generate an inappropriate price signals to customers and generators. To overcome these defects, the utilization of optimal power flow(OPF) is suggested to get the system loss deviation in this paper. 30-bus system is used for the case study to compare the MLF results by the power flow and the OPF method for 24-hour dispatching and pricing, Generator payment and customer charge are compared with these two methods also. The results show that MLF by OPF reflects the power system condition more faithfully than that of by the conventional power flow method

The purpose of this study is to examine the concepts of cultural administration and art management, their context, and elements that each concept pursues, and to establish the domains and systems of cultural administration and art management in Jeju. Seven values were selected through the consideration of commonalities and differences and previous studies, and sub-indicators of each value were determined. Factors were analyzed using the AHP method. Cultural administration is based on the areas of publicity, equity, and transparency, while art management is based on productivity, publicity, and responsiveness. Cultural administration needs to focus on a system for the preservation and utilization of local culture, co-evolution of culture, and expansion of culture and arts education. Art management needs to focus on the level of achievement of goals, the level of output versus input, and the system for preserving and utilizing local culture. In addition, it was found that there is a need to establish a system in Jeju with a common aim of the co-evolution of culture and preservation and the utilization of local culture.
