Securitization was meant to disperse credit risk to those who were better able to bear it. In practice, securitization appears to have concentrated the risks in the financial intermediary sector itself. This paper outlines an accounting framework for the financial system for assessing the impact of securitization on financial stability. If securitization leads to the lengthening of intermediation chains, then risks become concentrated in the intermediary sector with damaging consequences for financial stability. Covered bonds are one form of securitization that do not fall foul of this principle. I discuss the role of countercyclial capital requirements and the Spanish-style statistical provisioning in mitigating the harmful effects of lengthening intermediation chains. For Korea, the stability of funding emerges as a key consideration. Covered bonds may play a role in stabilizing the funding arrangement for banks.

On January 1, 2003, the motor vehicle management system in Korea was transformed from government's vehicle type approval to manufacturer's self-certification. The motor vehicle recall system with self-certification is an essential mechanism to place the liability of the vehicle defects on manufacturers and hence protect consumers from automobile accidents. This study provides a methodology to measure the benefits of motor vehicle recall system in two categories: benefits of reduction in traffic accidents and benefits of severity reduction in traffic accident. Applying the proposed methodology, the benefits of implementing motor vehicle recall system in Korea were estimated. It was estimated that 745 traffic accidents, 12 fatal accidents, and 1473 injury accidents were respectively reduced in 2002 due to implementation of motor vehicle recall system.

This study tries to measure the change in the state dependence of the three labor supply choices (part-time, full-time, and the state of unemployed) in Korean married women's labor market by estimating the dynamic multinomial logit model based on MSL (maximum simulated likelihood) method. A component representing individual's unobserved characteristics has been introduced, because it is crucial to control for unobserved heterogeneity in assessing the state dependence. Estimation results show that the state dependences of the three alternatives have strengthened recently. Therefore, part-time job has become more likely to be functioning as an extra option to participate in labor market rather than a bridge(stepping stone) or shelter between unemployment and full-time job.

Regulatory systems for decommissioning of nuclear power plants in several countries, such as Japan, United States of America, Germany, United Kingdom, France, and Republic of Korea, are surveyed. In the survey, regulatory policies, legislations, licensing process, inspection and public involvements for decommissioning are identified and compared. Afterwards, the survey results will be utilized as a reference to establish the improvement directions of domestic regulatory system.

It is the content and scope of this study to analyze the problems of the current wireless service and the classification system of the radio station, and to examine the case of radio control in Japan and to establish a reasonable and efficient radio wave management plan. The results of this study can be used as basic data for reorganizing the legislation on radio wave enforcement ordinance, radio services and radio station classification standards. It is expected that it will be possible to improve the compliance and efficiency of the radio station licensing and inspection service while enhancing the policy compliance in the practical work by providing detailed explanations on the definition and classification system of the new radio task / radio station in the future.

Precise control of oxidizer mass flow rate is important for hybrid rocket thrust control. In this study, oxidizer mass flow rate control system is developed by using stepping motor which is controlled by Labview program. Gox is used for oxidizer and PolyCarbonate, PolyEthylene, and PMMA is used for solid propellant. To suppress thrust oscillation during thrust control experiment, schematics of the experiment is analysised and revised. Results show that thrust oscillation is suppressed successfully.

Warranty contracting for pavements construction has been widely used in Europeans countries, Japan, and the U.S. and the benefits of warranty contract has been proven. This research investigated the European, U.S., and Japanese warranty contract policies and compared pros and cons. The most appropriate warranty contract policy solution is developed to fit in the Korean construction industry culture. Three main conclusions have been developed in this study: (1) performance specifications should be developed; (2) the systematic method is required to estimate the appropriate costs of performance bond and warranty period, etc.; and (3) short and long term plans for adopting performance warranty contract in Korea are suggested.

The decision of the USA to found the USF(Universal Service Fund) in 1983, which was aiming to support basic telecommunication services provision at affordable price in rural and high cost areas, has triggered many countries to introduce universal service support mechanisms. Korea has been also operating a universal service support mechanism since 2000 but there are lively controversies on the change of the existing support mechanism. This paper, first, will review universal service support mechanisms in major countries including USA, EU, Chile, Peru and Japan. Second, this paper will classify types of the mechanisms and review merits and demerits of the mechanisms. Finally, this paper will derive some implications for the improvement of domestic Mechanism.

Along with the launch of National R&D Program in 1982, National R&D licensing policy began to operate in order to expand and promote the outputs of R&D. Even though various studies attempted to draw plans to improve the National R&D licensing policy, most of their focus was limited to the collection and allocation structure of royalty. Thus, with the aim of approaching National R&D licensing policy in a whole cyclic perspective [from collection allocation to execution' post control], this study incorporates interviews with specialists and officials in charge of technology licensing fee, Industry-University-Institute surveys as well as literature review. Through this endeavor, suggestions are made in the aspects of (1) National R&D licensing policy reformation, (2) Technology licensing fee collection and allocation structure refinement, (3)Post control system establishment.

본 연구에서는 홍수시 제내지 침수로 인한 큰 인명 및 재산 피해의 가장 큰 원인이 되는 제방 붕괴과정을 제방의 침식 및 세굴이론 등 물리적 이론에 근거하여 해석하고 이를 토대로 하천제방 붕괴 모형을 개발하였다. 개발된 모형을 이용하여 하천제방 붕괴 모의를 수행하여 제내지의 2차원 침수양상을 분석하고 이를 이용하여 침수위험도를 작성하였다. 작성된 침수위험도는 제내지에 거주하는 주민들이 효율적으로 제방붕괴에 대한 대처할 수 있을 뿐만 아니라 제방붕괴로 인한 홍수재해보험 보험요율 산정시 침수위험도에 근거한 합리적 산정이 가능할 것으로 판단되었다. 본 모형의 적용 결과 홍수로 인한 제내지 침수위험도 산정을 위해 하천흐름-제방붕괴-제내지 침수해석을 연계하여 일관성 있게 모의할 수 있는 수치모형을 개발하여 실제 유역에 적용한 결과 제내지에서의 침수심, 침수면적, 하천 홍수위, 제방붕괴 폭 등이 합리적으로 계산됨을 알 수 있었다. 시간에 따른 제방 붕괴폭은 기존의 모형에서 사용하고 있는 순간적, 선형적인 붕괴가 아니라 포물선형의 붕괴가 이루어지고 있었으며 시간에 따라 붕괴폭도 합리적으로 계산되고 있음을 알 수 있었다. 제내지의 침수심을 토대로 제내지 홍수시 침수위험도 산정기법을 개발하여 위험도를 산정한 결과 하천변에 위치한 지역이 위험도가 무조건적으로 높은 것은 아니라 지형에 따라 달라질 수 있음을 나타내었다.
