This paper describes a theoretical model for investigating the relationship commitment of trade portal site 6C's. This research is the first to empirical test the causal relationships in Trade portal site. The relationship commitment for e-Trade portal site are tested here using data from 195 samples. Research methodology used in this study was mainly survey and questionnaire. Structural equation model is used in the hypotheses test. the results support all hypotheses involving hypothesis 1 and 6. The major finding of this paper would be summarized as followed: 1) Perceived relationship commitment of e-Trade site 6C's is positively related to contents, community, communication, customization in e-trade activity level and activity range of trade practical 2) Perceived commerce of electronic trade site is negatively related to the relationship commitment of trade companies. 3) Perceived e-trade site in electronic trade connection is positively related to the re-activity intention. In examining the relationships commitment of the factors, e-trade potal 6C's show in significantly by Contents, Community, Communication, Customization, Re-activity intention, but that show in not significantly by Commerce factor.

A comprehensive electronic trade portal such as the electronic bills of lading, e-negotiations and so on, is developed by the Korea Ministry of Knowledge Economy and International Trade Association and serviced by KTNET. The portal, so called u-TradeHub, formally started to provide its services on 22nd May, 2009. If the shipper issues electronic bills of lading, the negotiating bank examines it through the established e-Nego system. However, the issuing bank overseas cannot examine the electronic bills of lading, because any interactive system does not exist. So, after the e-Nego, the electronic bills of lading gets automatically transformed into the paper-type electronic bills of lading and issuing bank examine paper B/L. In process of examining documents, the beneficiary using electronic means in letter of credit transactions may face some risks such as the corruption to the electronic bill of lading after its issuance by the carrier, the corruption after e-Nego and the corruption after the presentation to the issuing bank. In this paper, we studied the problems on corruptions to occur in the middle of the examination process of the electronic bills of lading and suggestions how to solve them are discussed.

This thesis examines the problems faced in the electronic trade specialized service provider for which improvements are necessary, and suggests various ways of overcoming those problems. First, from the legal aspect, it is necessary to clarify the scope of duties as well as to expand the threshold for entrance and business areas through the amendment of related laws. Second, from the operating aspect, the e-trade specialized service provider should be able to provide convenient work spaces through user-centered interface by connecting, integrating, automating and simplifying various services scattered around through the establishment of an operating system. Third, from the institutional aspect, trade firms should be able to perform e-trade duties without difficulties by specializing and increasing the size of the e-trade specialized service provider system and strengthening job competence. For this, it is required to improve legal registration requirements to enhance the reliability of the e-trade specialized service provider system and secure its financial capacity.

Considering rapid development of Internet Portal Site Contents in Korea, it is an important issue to analyze consumers' satisfaction and e-loyalty. This research develops, and empirically test a model for explaining/predicting the satisfaction and e-loyalty with internet-based Electronic Trade Site. This paper describes a theoretical model for investigating the Satisfaction and e-Loyalty of the Electronic Trade Site. This study investigates the concept of the satisfaction, e-loyalty in Electronic Trade Site and its determinants, and tries to establish e-loyalty analyzing model. The model of the satisfaction, e-loyalty electronic trade site is tested here using data from 158 samples. Based on the research model, a comprehensive set of hypotheses is formulated and a methodology for testing them is outlined. some of the hypotheses are tested empirically to demonstrate the applicability of the theoretical model. In examining the relationships of the determinants factors, service quality satisfaction show in significantly by Reliability, Information Provided, Trustworthiness, Convenience, International of contents but that show in not significantly by Interaction. In addition, Electronic Trade site retention shows indirect effect between customer satisfaction and referral. Although our research can not show the determinants of e-loyalty in the electronic trade site the empirical result give both theoretical and managerial implication for managing the consumers' satisfaction and e-loyalty in electronic trade site.

Korea is one of the most advanced countries in terms of nation-wide readiness for conducting complex trade processes in an electronic way. Since various trade processes are well-known for their complexity and cost as well as time consuming characteristics due to required collaborations with involving parties, automation and efficiency are always the main concern of trade-related practitioners. Using information technology can be a possible solution to this problem and Korea has developed the national e-trade infrastructure called "u-Trade Hub." In this paper, we propose the framework to enhance the national integrated e-trade system called "u-Trade Hub," which is ready to be released for commercial use in near future. We propose the framework to upgrade u-Trade Hub in four directions: (1) opening, (2) strengthening community feature, (3) modularization, (4) seeking profitability. In this paper, we study and compare national e-trade environment of other countries such as Singapore and Japan. Then, we analyze and design the enhanced e-trade infrastructure based on Web 2.0.

금속판/형과스크린 계측기와 CCD 카메라를 이용한 방사선영상장치가 현재 전자포탈영상에 널리 쓰이고 있다. 이 장치의 효율적인 영상획득을 위해 계측효율이 좋고, 공간분해능력이 뛰어난 금속판/ 형과스크린 계측기의 두께를 최적화할 필요가 있었다. 이 논문에서는 금속판과 형광스크린의 두께가 계측효율과 공간분해능에 미치는 영향이 연구되었다. 이 결과는 치료 엑스선 영상장치에 쓰일 수 있는 금속판/형과스크린 계측기의 최적화된 두께를 결정하는데 쓰일 수 있다. 몬테칼로 방법을 이용하여 계산한6 MV 선형가속기에서 발생되는 엑시선의 에너지 스펙트럼을 바탕으로, 여러 가지 두께의 금속판/형광스크린에 대하여 계측효율과 공간분해능을 계산하였고, 이를 실험을 통해 검증하였다. 계측효율은 입사된 엑스선의 에너지가 형광스크린에 흡수된 비율로 계산되며, 공간분해능은 흡수된 에너지의 공간 분포를 통해 계산되었다. 계측효율은 금속판의 두께에 의해, 공간분해능은 형광스크린의 두께에 의해 결정될 수 있음을 본 연구를 통해 확인할 수 있었고, 이로써 특정이용에 관련된 금속판/형광스크린의 두께에 대한 서로 보상 (trade-off) 관계에 있음을 계산과 측정결과를 통해 확인할 수 있었고, 이로써 특정이용에 관련된 금속판/형광스크린 계측기의 최적화된 두께를 산출할 수 있게 되었다. 계산을 바탕으로 CCD를 이용한 전자포탈영상장치의 시작품을 설계 및 제작하였고 팬텀을 이용하여 영상을 얻었다. 단일 프레임 영상은 노이즈가 많으나, 프레임 평균 방법을 이용하여 영상의 질을 향상시킬 수 있었다.

Purpose - These days, an individual user, private entity, hears everyday news of hacking and personal information leakage in the era of a most-connected society. This study investigates cyber attack, cyber insurance and distribution channels for insurance goods in South Korea by analyzing various cases of cyber attacks in domestic and overseas case. Research design, data and methodology - This study adopted various study cases instead of the one large case for deep quality analysis, and focused on various cases of domestic and overseas cyber attacks with insurance. Result - As a result of analyzing the cases that were hacked, types of massive losses and damages arising out of internet blackout due to cyber risks are paralyzation of public and private website and portal, electronic administrative system, public infrastructure, and consequently a normal operation of nation is impossible. These losses and damages however can be coverable under cyber insurance. Conclusions - This paper suggests insurance carriers, as suppliers, should provide multiple channels to sell to the customer and should expand the strategy of advertisement and promotion in order for them to change their mind and compare the price and value of the information of individual users and private entity in view of cost savings.
