This paper is analyzing the SoC policy of major nations as the U.S, Japan, Europe, Taiwan, China and draw the suggestions for the development of semiconductor industry in Korea. SoC is the non-memory semiconductor to support and put into action the function of system. SoC is big market over the 200billion dollars and have a huge potential for new IT convergence market. Developed countries as the US, Japan, and Europe have enforced the industrial competitiveness by company investment and Taiwan supported the SoC Industry by government fund. Korea is No.1 superpower in DRAM semiconductor, but very weak in SoC Industry. We should secure the competitiveness of SoC Industry by the development of core technology, planning the growth policy, and building the cooperative model to leap the SoC power nation.

본고(本稿)에서는 다양한 형태의 금융충격(金融衝擊)의 거시경제효과(巨視經濟效果)를 분석하기 위해, 모든 금융충격(金融衝擊)을 통화의 지불수단으로서의 이용률(利用率)을 급격하게 변화시킴으로써 화폐시장(貨幣市場)에 초과수요나 초과공급을 초래하는 현상으로 이해하고, 동 충격을 유통속도충격(流通速度衝擊)과 통화승수충격(通貨乘數衝擊)으로 분리하여 그 규모를 추정할 수 있도록 전자(前者)는 은행의 예금회전율(預金回轉率)과 현금통화보유성향(現金通貨保有性向)에 의해, 후자(後者)는 현금통화보유성향과 지급준비보유성향에 의해 설명하는 일반적인 모형을 개발했다. 동 모형을 아용하여 80년대 이후 우리나라의 금융충격사례(金融衝擊事例)에 대해 분석한 결과는 다음과 같다. 82년 거액어음사기사건과 7.3조치에 의한 실명제예고조치(實名制豫告措置)는 M2를 3% 이상 감소시키는 효과를 초래하였으나, 실제로는 통화당국의 대응으로 오히려 3.0% 수준의 M2가 초과공급된 반면, 1988년의 금융실명제(金融實名制) 실시예고와 민간(民間)에 의한 1993년 8월 12일의 금융실명제실시예견은 M2를 각각 3.9% 및 4.9% 감소시키는 효과를 초래하여 정부의 통화공급대응(通貨供給對應)에도 불구하고 결과적으로는 각각 0.8% 및 0.6% 수준의 M2 과소공급을 초래한 것으로 추정되었다. 93년 8월 12일의 금융실명제 전격실시는 개략적으로 7~8%의 M2 통화량감소효과를 초래한 것으로 추정되지만, 실제로는 통화당국(通貨當局)의 신축적 통화공급으로 0.3~0.6% 정도의 M2 초과공급이 이루어진 것으로 추정되었다. 한편 본고(本稿)에서는 이와 같이 추정된 사례별 금융충격의 거시경제효과(巨視經濟效果) 시뮬레이션 결과(結果)도 같이 보여주고 있다.

A construction project consists of a variety of contracts for the completion of work. The large number of contracts involved in a single project increases the likelihood that disputes will arise between the parties involved regarding the terms of service. Actually, there are many disputes that are caused by a change 0 order. While such disputes should be settled by interpreting the terms stipulated in the agreement entered between the two parties, the process of dispute settlement is often restricted to arbitration and lawsuit, and as a result the parties tend to avoid it due to its inefficiency. For this reason, in Korea it is hard to find cases of interpreting terms of service, while in the U.S. it is easy to find diverse cases of interpreting terms of service, since there is a process of dispute settlement by each stage by the party who has placed an order. Therefore, this study presents analysis of case studies of contract changes, looking specifically at changes in the scope of the work, changes in quantity, changes in the period of implementation, changes in the method of implementation or attitude, changes in items provided by the government or the delivery place, and the acceptance of such change procedure by a contractor, and the adjustment of a reduction.

It has been shown that the lack of sufficient defense industry cooperation between Korea and the US. The severe imbalance in defense trade between tow countries and Korea's weak defense industrial base has been a problem. This paper suggests the enhancement of defense industry cooperation with the US as a defense policy. The US policy has been changed to utilize the globalization of defense industries. The following cases were analyzed to show the policy change; The security of supply arrangement with 6 countries, the defense cooperation treaty with the United Kingdom and Australia. the defense Memorandum of Understanding with 23 countries, and the international cooperation with 8 countries for F-35 JSF program. Korea government needs to sign a defense MOU with U.S. and the defense industries are recommended to increase the opportunities of weapon system co-development and co-production. So that the Korea defense industry may improve competitiveness and to overcome the current weaknesses.

The economy of the EU left behind the U. S. economy in many different aspects and the gap is widening. One major reason that promoted the EU's leading position is the ability to continuously advancing industrial technology and therefor secures the EU's leading position through a high level of competitiveness. The role as a powerhouse of the technological development is nurtured by a systematic attempt of the EU commission to stimulate international cooperation. Although the EU is focussing its efforts on international cooperation between EU members states, nonmembers, namely Korea, can benefit from this policy as well and generate win-win outcomes for both cooperating partners. The paper aims in the first chapter to introduce international technological cooperations in general. The second chapter identifies the political approach of both countries towards technological cooperations. The third chapter introduces the research method. In the forth chapter is analyzed a case study of two cooperation projects between Japan and the EU. Finally, implications for Korean policy makers are given.

South Korea is seeking for a solution to the problems of traffic congestion and environment: the increase of bicycle use. However many people feel that using a bicycle is inconvenient. Therefore, we developed bicycle level of service model from the user's perspective so that the existing bicycle roads can be evaluated and improved. The purpose of this paper is to develop a bicycle level of service (LOS) model by considering user's satisfaction and multiple factors that affect bicycle LOS. Bicycle LOS criteria is estimated by applying an ordered probit model, which is suitable for research relating to choice. In addition, we determine the bicycle LOS using three-level(A-C) LOS structure from the user position considering the satisfaction level that people can distinguish clearly. The results show that the bicycle LOS is largely determined by the bicycle road width. Other factors are involved as well, including bicycle road type, the number of access and egress point on the bicycle road corridor, pedestrian volume, and frequency of meetings.

Collaborative technology development is now one of the most significant modes of activity in the global scientific community. However, the international cooperation of science and technology simultaneously provides opportunities and challenges, and the results of global R&D collaboration can be positive or negative as the cooperation conditions of the parties may be different according to the types or characteristics of the participants and the pattern, purpose, and motivation of cooperation. In order to minimize the risk and improve the performance of cooperation, more comprehensive as well as micro-level research is needed. This study investigates a case of successful collaborative R&D conducted by several firms, universities, and public research organizations in both Korea and the U.S.A. The aim of this study is to identify the factors of successful R&D collaboration.

To evaluate the formulae for the stability of riprap, the formulae of Isbash, California division of highway, Netherlands, ASCE, Pilarczk, and Maynord are comparatively analysed with the experimental results. The critical velocity which initiates the motion of riprap is increased with the weight and the size in diameter and the riprap size with water depth, Froude number, shear velocity with mean velocity, Shields parameter have great correlation with them. The results by 6 formulae are overestimated in riprap size in diameter and the result by Maynord formula proposed by U.S. Army Corps of Engineers estimates rather correct. The results by Isbash, Netherlands, and Pilarczk are overestimated in riprap weight but the result by California division of highway formula coincides with experimental result. In the experimental results of model riprap artificially made by gypsum with light weight density, the critical velocity is increased with shape factors. The critical velocity appears greater in regular arrangement of model riprap than in random arrangement of it. Therefore the shape factor and the degree of interlocking are an important parameters in riprap stability.

Activities to search for the new business items of the future in the public and private sectors, has been actively progressed. These generally come from the situation that current technology can not guarantee the future as the technologies and products are going to reach a certain limit. However, prior to these activities, it is necessary that watching for existing technology they're now actively using. It can provides keys to how to find new business items for the future based on the current situation of the technology and products lies. This study collects citation information from U.S. patents from 1976 to 2007 and analyses quantitatively top 1% of cited patents during the last five years of from 2003 to 2007 in the metal sector. It is shown that traditional patents have very long life cycle in the metal sector.
