최근 몇 년 사이에 인터넷(Internet) 공간상에서 거래되는 선박 매매 사이트의 출현으로 인하여 사이버해운거래 시장이 형성되고 있다. 인터넷은 다양한 정보제공자에 의해 광범위한 분야의 정보를 멀티미디어 형태로 전달한다는 점에서 매우 각광을 받고 있지만 이용자의 증가로 무수한 정보들이 걸러지지 못한 채로 Web상에 존재하게 되었다. 따라서, 이러한 정보들을 체계적으로 정리하고, 이용자들의 구미에 맞게 가공된 정보의 필요성이 대두되게 되었다. 이러한 문제를 해결하기 위해서 이용자가 원하는 것을 스스로 인지하고 판단하여 요구사항을 해결해주는 "지능적 대리인" 또는 "지능을 가진 도우미"라고 일컫는 지능형 에이전트(Intelligent Agent)의 필요성이 대두되었다. 지능형 에이전트는 그 다양한 기능으로 인하여 인터넷에서 매우 중요한 요소로 자리잡게 되었다. 우리나라를 비롯해서 선진 해운국에서는 선박매매사이트를 개설하여 사이버 공간상에서 거래를 수행하고 있지만, 사이트별 등록된 선박의 수가 많지 않을 뿐 아니라 거래대상 선박의 표현 방식도 사이트별 국가별로 매우 달라, 선박 매매 시 충분한 매매 대상 선박정보를 획득하기 어려운 실정이다. 본 연구는 선박매매 시 고객에게 매매 선박정보를 제공해주는 선박매매용 에이전트 설계를 목표로 하고 있다. Bargainfinder, Bargainboat, Shopboat, Price watch 등 쇼핑몰을 대상으로하는 비교쇼핑에이전트는 상용화되어 운영되고 있지만 선박매매용 에이전트에 관한 연구는 시도되지 않고 있다. 본 연구는 선박매매용 에이전트를 개발하기 위한 설계연구로서 다음 사항에 대한 연구가 시도되었다. (a) 구매 선박에 대한 요구? 표현 방법 (b) 관련 선박의 표현, 등록 및 색인방법 (c) 공급 선박의 분류와 표현 방법 (d) 에이전트의 정보 수집을 위한 메시지 표현방법 (e) 수집된 선박정보의 데이터베이스 (f) 요구 선박을 찾아주는 정보제공 서비스가 요구된다. The IT for e-Business performance is composed of the financial performance of a corporation, the effectiveness of IT itself, the suitability of processes and so forth. For the last 30 years many studies about IT evaluation have been conducted, most cases have been measured inclusively in terms of technology level, information level, functional level and management level. However these management oriented evaluation models are too narrow to evaluate IT for 3-Business. The IT in a corporation needs to be measured broadly. Corporate performance of IT needs to use models in the past and concentrate on environmental characteristics. This study intends to find more practical IT evaluation models for e-Business. We found two standardized IT process evaluation models, CMM and SPICE which are analyzed in terms of process in an organization. Afterwards this study will suggest an appropriate conceptual model for evaluating IT for e-Business.

To achieve the ULSI goals of higher density and greater performance, STI(shallow trench isolation)-CMP(chemical mechanical polishing) process has been attracted. Recently, the direct STI-CMP process without the conventional complex reverse moat etch process has established by using slurry additive with the high selectivity between SiO2 and Si3N4 films for the purpose of process simplification and in-situ EPD(end point detection). However, STI-CMP process has various defects such as nitride residue, torn oxide and demage of silicon active region. Also, it was difficult to assure the suitable process margin in the STI-CMP process. To solve these problems, in this paper, we discussed to determine the control limit of process, which can entirely remove the oxide on nitride film from the most area of high density as reducing the damage of dense moat area and minimizing dishing effect in the large field area. We, also, evaluated the wafer-to-wafer thickness variation and the day-by-day reproducibility of STI-CMP process after repeatable tests.

As the device geometry shrinks to the deep submicron region, chemical mechanical polishing(CMP) planarization become a more essential technique of advanced ULSI process. Also, CMP process was required for the global planarization of inter-metal dielectric(IMD), inter-level dielectric(ILD) layers and interconnections with free-defect. Especially, the complete global planarization of IMD, ILD and interconnections can be achieved only with the CMP process. However, as the IMD and ILD layer gets thinner, several problems were found in the CMP process. It does have various problems such as dishing effect, torn oxide defects and nitride residues in oxide. So, it leads to severe circuit failure, which affects yield. In this paper, we studied the characteristics of polishing pad, which can apply STI-CMP process for global planarization of multilevel interconnection structure. Also, we investigated the effects of different sets of polishing pad, such as soft and hard pad. As an experimental result, hard pad showed center-fast type, and soft pad showed edge-fast type. Totally, the defect level has shown little difference, however, the counts of scratch was defected less than 2 on JR111 pad. Through the above result, we can select optimum polishing pad, so we can expect the improvement of throughput and device yield.

Recently we face crisis of foreign exchange and acutely requires attraction of foreign capital that motivates investment of multinational corporation. Accordingly, it is important to study. multinational corporation. If we draw foreign capital unconditionally, it can be avoid the crisis temporarily but it will occur a big side effect in a long term. Regarding to study on this thesis, in chapter 2, it is outlined national economic and the role of foreign capital through study on bibliography. In chapter 3, it is shown that the definition and the characteristics of corporation so that it is studied major direct investment in the foreign investment part and multinational corporation has an influence in the industry. it is crucial to prove motivation of investment of multinational corporation, after it is tried its case of model in chapter 4. There are factors for motivating of multinational corporation such as investment environment competitiveness, achievement of business and standardization. It is summarized following; First of all, in terms of investment environment, it requires for reducing complicated administrative procedure substantially in order to promote domestic investment of multinational corporation. Second of all, with competitiveness the cause of obstacles are to have difficulty in attraction high personnel with high wages and low-level of price competitiveness in inside and outside of country. It is suggested that productivity is in proportion to proper salary in our society not to turn multinational corporation steps to other development countries. Third of all, according to achievement of business, multinational corporation gets profits that exporting from domestic market. Currently it is a major cause of investment in the marketplace. However, the boycott of foreign brand with no condition it will lead public's rejection as well as multinational corporation's investment contraction or its withdrawal. Simply the consumption of domestic brand is equal to avoid foreign exchange crisis might bring a contrary effect. Thus, it asks for desirable consumption movement under a delicate study. Finally, the reason of many multinational corporations existence is almost same as strategy of standardization's end. As it executes standardization of multinational corporation, it will reduce the cost(money, time, human labor). It can be a huge attraction to multinational corporations. Therefore, it is desired to the utmost to improve restriction of possible variance so that multinational corporation reform standization in a given conditions as a matter of management. In this study, as it was dealt with a wide range, it was difficult to cover up all the details of strategy establishment. In the future, it is expected to continue elaborate study for further development.
