The purpose of this paper is to investigate the structure of cost-sharing for oriental medical services in the national health insurance. Out-of-pocket payment in ambulatory oriental medical care is a co-payment of KRW3,000 up to total expenses of KRW15,000, and co-insurance rate of 30% thereafetr. The empirical analysis based on medial claims data shows that the frequency of medical claims for outpatient care are mostly concentrated just below a total expenses of KRW15,000, and it decreases beyond a total expense of KRW15,000, while it rebounds between KRW17,000${\sim}$20,000. This means the current co-payment(KRW3,000) in oriental medical services should be applied up to a total payment of KRW17,000${\sim}$20,000, or the level of co-payment should be adjusted upward to KRW45,000 in order to be consistent in cost-sharing, between co-payment and co-insurance.

The purpose of this study was to estimate the magnitude of patient's actual cost-sharing for hospital services in the National Health Insurance which has been estimated with only a few hospitals or limited number of patients. Also we aimed at analysis of factors influencing the magnitude. Sources of analyzed data were two databases. 1997 medical benefits record of the National Federation of Medical Insurance and 1997 Statistics for Hospital Management from the Korea Institute of Health Services Management(KIHM). We merged two databases and related records for 224 hospitals. based on the identification details of each hospital. The average percent of patients' cost-sharing was 51.7% of total hospital revenues from the insurance. with 40.3% of revenue in inpatient and 67.4% in outpatient. respectively. The contributing hospital factors to the magnitude of cost-sharing were size of hospitals. teaching status. location. number of employed physicians. etc. Larger and university hospital. urban location. and with more physicians were positively correlated with higher level of cost-sharing. Additionally, the higher the expenses of inpatient's treatment was, the higher the size of patient's cost-sharing was. These findings suggest that present level of patients' cost-sharing is quitely high and it is urgent to reduce the patient's cost-sharing to the reasonable level. It would be necessary to extend the coverage of insurance benefits and to develop policies focusing on larger hospitals and inpatient services.

The purpose of this study is to investigate the factors affecting family caregiver financial burden of out-of pocket expenses for the nursing home service under Long-term Care Insurance System. We conducted a national cross-sectional descriptive survey from July to September 2010 to collect data based on the long-term care benefits cost specification. Total 1,016 family caregivers completed questionnaires. 185 subjects of total were excluded from the data analysis due to being answered by user(18 cases), or caregivers not to pay for services expenditures(122 cases), having a missing data on family caregivers characteristics(45 cases). Finally, 831 subjects were included in the study. The average financial burden was 3.18(${\pm}0.71$). We divided subjects into two groups by level of burden, high-burden group and low-burden group. In the result of the multiple logistic regression analysis, family caregiver financial burden was significantly higher in family caregivers with ages 40 to 49 compared to less than 40, lower educational level, unsatisfaction for long-term care service, high percentage(more than 50%) of cost-sharing and high total out-of pocket expenses(more than 300,000 won) for long-term care services. Also, Family caregivers who are spouse felt higher financial burden compared to son. This study is meaningful as the first attempt to measure family caregiver financial burden for long-term care service and to identify factors affecting the financial burden. Family caregivers felt financial burden of out-of pocket expenses for the nursing home service. The policy makers, the insurer, and the providers need to pay attention to ease family caregiver financial burden.

The paper's suggestion is about hereditary facts between family members. Diagnosing patients from the point of patients temporary conditions, and so performing primitive examinations and treatments, can lead not only to frequent wrong diagnoses, and to huge medical expenses and times to the patients, but even to critical situation of patients or taking lives away. As a means to cut these cases down to a minimum, sharing medical treatment information between family members is suggested. This approach makes possible understanding physical constitution and environment between family members, and can result in bringing a faster treatment effect if some family member suffers from a similar disease. This approach, since a participation in a family membership effectuates all of family members, can minimize the membership fees, thus enabling inter-family health care on a home doctor basis.

This study discusses factors that affect on female workers' stress from nurturing. Referring to the first research (2008) and the second research (2009) of KLoWF, the study analyzed the data of 218 female workers with one or more preschool children. The results from the analysis are as the following. First, the female workers who acknowledge her image as a traditional woman are more likely to be exposed to greater stress. Therefore, now working mothers need to free themselves from the traditional idea. Second, since it was clearly observed that husbands' who share family responsibilities has a significant impact on women's stress from nurturing, a new focus should be on the effectiveness of husband's sharing of family responsibilities, whereas it has been mainly focused on education of working mothers. Third, considering the result that nurturing expense variable showed a significant statistics, there is a desperate need of a political task to support nurturing expenses.

Car sharing, which is considered as a good example of innovation in the transportation sector, is a type of use in which a plurality of people share a single vehicle for a short period of time. It is divided into various types, NFP (Not For Profit) operated by a non-profit organization, B2C (Business to Customer), which is operated by a company, and Peer to Peer (P2P), which is directly connected to an individual. Among them, P2P car sharing is a method of sharing personal vehicles owned by individuals. It has the merit of reducing traffic congestion and providing for efficient traffic demand management by reducing the purchase rate of additional vehicles and minimizing the number of idle ones. This study examines the introduction of P2P car sharing in order to develop a traffic demand management policy and facilitate the transition to a sustainable transportation system. The spatial extent of the study consisted of apartment complexes in Seoul. In apartment complexes, it is possible to minimize the level of expenditure, such as operating expenses, by utilizing the APT management office and there is no difficulty in securing the necessary parking space. Therefore, apartment complexes were selected as the spatial range.

Although the National Health Insurance, many people sign up for private health insurance to alleviate their financial burden. In this study, we analyzed the relationship between private health insurance and subjective financial burden about cost sharing. To confirm the effect we conducted the binary logistic regression by utilizing the Health Care Policy related to public survey. The private health insurance have a significantly association with the subjective financial burden about cost sharing. People who uninsured to purchase private health insurance were more likely to have the burden. Therefore, given the low participation rate of private medical insurance for high age and low income group, we suggest the need for redefining the role of private insurance to enhance the function and resolve equity issues to prepare for the burden.

As a way to allocate lots of orders to many participants for vehicle allocation problem, this study has used an agent negotiation based reverse auction model. This agent negotiation provides coordination functions allowing all participants to make a profit, and accomplishing Pareto optimum solution from the viewpoint of a whole trucking cargo transportation network. In order to build a strategic cooperation relationship based on information sharing, this agent negotiation provides a coordination mechanism in which all the participants including consignors, brokerage firms, and car owners are able to attain their own profits, and also that ensure a competitive market. This study has tried to prove that the result of an agent-based negotiation is the Pareto optimal solution under the present market environment. We established a mathematical formulation for a comparison with the Integer Programming model, and analysing e-Marketplace, structure of shipping expenses and brokerage system in the trucking cargo transportation industry.
