The National Health Insurance (NHI) has been the main body of health care system in Korea for the last 30 years since the NHI was founded. However, the inefficient management and strong regulations of the NHI have hindered the development of health care industry. The establishment of the MB government, whose interest lies on economic growth rather than equity, is expected to help the health care services gain a momentum. The essential measures that can step up public health care services overall are the following: the introduction of competition within NHI, the activation of private health care insurance, and the allowance of for-profit hospital. The private-public mix with market mechanism would level up the health care service for the public.

In this paper, the unbiasedness hypothesis cannot be rejected for JPY. It means that Japanese forward exchange market is efficient. This implies that there would not be an unusual profit from speculation. However, the unbiasedness hypothesis can be rejected for THB, HKD, IDR. It means that Asian forward exchange market is inefficient. This implies that there would be an unusual profit from all available information. This suggests that forward exchange rates cannot be an unbiased estimator of future spot exchange rate. This result explains that the actual pricing for forward rate is not based on the international financial market's pricing mechanism of interest rate parity theory, but rather depends upon that simple market expectations and aspirations.

본 연구는 공급망 운영에서 가장 기본적이고 필수적인 연구 분야인 공급자의 선정과 수요의 할당 문제를 해결하기 위한 방법으로 게임이론을 적용하였다. 특히, 가장 보편적으로 사용되고 있는 점진적 역경매 메커니즘을 비율적 형평성을 보장하는 구매 게임 방식과 공급망 전체 운영의 수익성이라는 관점에서 비교 분석하였다. 서로 다른 두 메커니즘의 정교한 비교 분석을 위한 전체 알고리즘을 제시하였으며, 구매게임을 이용한 공급자 선정 및 주문 배분의 최적해는 유전자 알고리즘을 통해 도출하였다. 전체 공급망의 수익성은 공급자와 구매자의 수익함수와 수익-비용 비율을 통해 평가하였다. 실제 현실의 공급망을 단순화한 모형을 바탕으로 본 연구에서 제안하는 방법이 전체 공급망의 수익성을 어떻게 향상시킬 수 있는 지를 간단한 실험과 통계 분석을 통해 설명하였다. 이를 통해 구매게임의 해가 역경매 방식에 비해 구매자의 수익성 감소를 통해 공급자와 구매자를 모두 포함하는 공급망 전체의 수익성을 크게 향상시킬 수 있음을 보였다.

이 연구는 이용자들의 자발적인 참여로 이뤄지는 블로그 생산이 결과적으로 가상공간의 이윤창출 메커니즘에 포섭되는 과정을 밝히고, 그 이면에 있는 이데올로기가 무엇인지 밝히려는 것이었다. 연구는 6개월여 동안 민속지학적 내용분석(ECA)과 참여관찰, 심층인터뷰 등을 병행하여 실시하였다. 연구결과 이용자들의 참여가 집약된 블로그는 다양한 직간접 방법을 통해 자본화 도구로 사용되고 있었다. 하나는 포탈이 블로그를 꾸밀 수 있는 아이템을 판매해 수익을 남기는 직접적인 방법이었으며, 다른 하나는 기업을 중심으로 블로그 저자의 온라인 평판과 신뢰도를 구매해 이윤창출 메커니즘으로 활용하는 간접적인 방식이었다. 이러한 이윤화 메커니즘이 성공을 거둘 수 있었던 것은 면접자들이 이윤창출의 기제에 포섭돼 있으면서도 이를 인식하지 못하고 역으로 자신은 인터넷을 능동적으로 이용하고 있다고 믿고 있기 때문이었다. 연구 대상자들은 아이템을 구매해 블로그를 꾸미도록 하는 포탈의 전략을 적극적인 자기표현 방법의 하나라고 여기고 있었고, 기업이 주도하는 리뷰어마케팅이나 블로그 마케팅을 통해 광고도구로 전락하면서도 정보를 제공하고 있다고 믿고 있었다. 이와 같은 '능동적 참' 이데올로기가 가상공간의 이윤화를 지속시키는 강력한 기제였다.

We suggest a distributed framework for task assignment in the computer-controlled shop floor where each of the resource agents and part agents acts like an independent profit maker. The job allocation problem is formulated as a linear programming problem. The LP formulation is analyzed to provide a rationale for the distributed task assignment procedure. We suggest an auction based negotiation procedure including a price-based bid construction and a price revising mechanism. The performance of the suggested procedure is compared with those of an LP formulation and conventional dispatching procedures by simulation experiments.

In this study, we consider the mechanism or the contract to mitigate inefficiency of individual and partial optimization in decentralized supply chain, which consist of a manufacturer and a retailer and In which the latter can increase demands by practicing her own promotional efforts. In that supply chain, we show to be able to achieve profit level in centralized channel by manufacturer's 'allowance' to retailer.

Although political uncertainty exists between China and Taiwan, the two countries have been expanding their economic exchange since the 1980s. That economic exchange is not limited to trade, and its investment segment is constantly expanding. The investment was one-sided by Taiwan in the past, but since a change in policy by the Taiwan government in 2009, Chinese capital is able to flow into Taiwan for direct investment. These kinds of policy changes related to investment between the two countries require follow-up actions such as profit protection for investors, elimination of investment limitations, simplification of investment procedures, and establishment of an investment dispute resolution system. The main topic of this study is the resolution mechanism for investment disputes between China and Taiwan. At present, an individual investment dispute between two countries is settled according to each country's own regulations for dispute resolution. However, these two countries have not prepared dispute resolution regulations related to cases of investment disputes between Chinese or Taiwanese investors and the Chinese or Taiwanese government, or between the Chinese government and the Taiwanese government. Moreover, they do not have any agreements related to investment disputes. Therefore, in this paper, I enumerate the regulations related to investment dispute resolution between China and Taiwan, and then I point out the problems and suggest solutions for improvement. Also, through this study, I would like to contribute to establishing and implementing an investment dispute resolution mechanism between South Korea and North Korea.

The presented scientific research substantiates the principles of the mechanism of the investment resources involvement in order to introduce innovations at enterprises in the context of digitalization using a resource-functional approach. The importance of attracting investment resources, which contributes to the modernization of production systems, the creation of a stable economic field of development of economic entities, is justified. The expediency of application of the resource-functional approach on research of the mechanism of attraction of investment resources for introduction of innovations at the enterprises in the conditions of digitalization is proved. The investment process is presented in the form of a chain of interdependent processes which include: attraction of investment resources, investments, increase of investment value, profit. It is proved that the mechanism of attracting investment resources for the introduction of innovations in enterprises in the context of digitalization cannot be considered in isolation from the process, due to the fact that the mechanism is aimed at performing specific functions. The functions of the mechanism include management, complex, coordination, monitoring, performance and control functions. Functions of the mechanism of attraction of investment resources for introduction of innovations at the enterprises in the conditions of digitalization are caused by the purposes of attraction of investment resources for innovative development; the presence of an objective nature; relative independence and homogeneity; implementation of functions in the process of investing in innovative activities of the enterprise.

To revitalize the trucking market, many studies are being done but it still has a lot of problems such as imbalance between supply and demand, poor profit structure of truck owners, ect. Therefore, it aims to study what kinds of prerequisite are needed to solve these problems through analyzing system structure and mechanism of the market. To achieve it, System Dynamics methodology, appropriate to make a simulation model and analyze dynamics of the system, is utilized. To obtain an empirical research point of view, time series data related on trucking market-provided by The Korea Transport Institute-are used. In addition, interview with a local representative logistics company and a ICD(Inland Container Depot) operation company is performed to find out technical and functional supporting factors to solve the existing problems in the market.

The procurement of generation and transmission/Distribution capacity in vertically-integrated electric industry is sufficient by facility construction in suitable time. However, the introduction of competitive electricity market increase the efficiency of availability for facilities and fuels. As a result, long-term capacity procurement is required for stable demand-supply balance since it is expected to maintain their generation capacity at a minimum for profit maximization. In this paper, a new long-term capacity procurement mechanism is proposed, which is able to assure supplemental contribution in competitive electricity market.
