본 연구에서는 광양항이 동북아 물류중심항만으로 성장하기 위한 하나의 방안으로 e-비즈니스 환경에 따른 웹사이트를 활용한 항만마케팅 전략을 제시하고자 한다. 즉, 항만을 e-비즈니스 관점에서 접근하여 단순히 웹사이트를 구축하여 대(對)고객 서비스를 지향하는 것이 아니라, 웹사이트 6C 요소에 따른 효율적인 운영방안을 제시하는데 목적이 있다. 반면, e-비즈니스 환경에서 웹사이트를 활용한 항만 활성화 방안에 관한 연구는 매우 드문 실정이다. 일부 항만마케팅에 관한 선행연구의 경우 이론적인 전개와 Off-line적 4P 전략을 제시하고 있어 e-비즈니스 환경에 따른 한계점을 가지고 있다. 그리고 6C 전략도 모델의 설정과 비교분석 과정에 있어 다소 구체성이 부족함을 보이고 있다. 이에 본 연구에서는 선행연구의 한계점을 보완하여 체계적으로 이론을 정립했으며, 현재 광양항 관련 3개의 웹사이트 운영 현황을 6C를 중심으로 비교 분석하였다. 그리고 분석결과를 토대로 6C 전략별 운영방안을 제시하고자 한다.

본 논문에서는 학습활동 중심의 컴포넌트를 기반으로 설계 구현한 u-러닝 허브사이트 시스템을 제안한다. 제안된 시스템은 u-러닝 환경에서 다양한 단말기를 통하여 교육활동이 이루어 질수 있도록 u-러닝 허브사이트의 기능을 컴포넌트 단위로 세분화 하며, 각 컴포넌트는 클래스들의 상속과 조합을 통하여 실시간으로 허브 사이트의 기능을 구성한다. 즉 접속하는 단말기와 프로그램의 특성을 파악하여 기본이 되는 부모 클래스를 바탕으로 자식 클래스를 추가하거나 조합하여 하나의 컴포넌트를 동적으로 구성하게 된다. 이러한 방식을 통해, 본 논문에서 제안한 시스템은 다양한 단말기를 지원 할 수 없는 기존의 e-러닝 시스템과 달리 동일한 시스템 하에서 시간, 장소, 단말기와 프로그램에 구애받지 않고 교육활동 서비스를 이용할 수 있는 유비쿼터스 러닝 환경을 제공한다.

High temperature co-electrolysis of H₂O-CO₂ mixtures using solid oxide cells has attracted attention as promising CO₂ utilization technology for production of syngas (H₂/CO), feedstock for E-fuel synthesis. For direct supply to E-fuel production such as hydrocarbon and methanol, the outlet gas ratio (H₂/CO/CO₂) of co-electrolysis should be controlled. In this work, current voltage characteristic test and product gas analysis were carried out under various reaction conditions which could attain proper syngas ratio.

This paper reviews the distinctive characteristics between e-Trade and e-Commerce in view of commercial arbitration in Korea and explores several improvements for the role of commercial arbitration. As the volume of e-Trade and e-Commerce has expanded day by day, there will be more disputes between traders no matter where the commerce may occur. But despite increasing of the disputes relating to e-Commerce transaction, it seems that the role of commercial arbitration has been shrunk instead. Korea needs to improve the role of commercial arbitration in order to meet and lead the age of u-Trade Hub(u-TH) service and to adopt an offensive or active attitude when arbitration used. Moreover, it is suggested that the competence of arbitration should not only be intensified more precisely but also be redesigned more systematically. Korea should take advantage of arbitration resources actively such as arbitrators as human resource and experiences as knowledge assets and also prepare the policy for sharing those arbitration resources between arbitrators more effectively.

Paperless trade is a new trade paradigm that has innovated on traditional trade procedures, which relied on manual work in the past, and applied an IT-based e-document standard. To realize paperless trade in Korea, a lot of efforts have been made. Korea has overcome many difficulties, a lack of awareness, trials and errors, etc. at the initial introduction stage and strived to establish a stable infrastructure through the government's policy support and active cooperation with the trade business communities and related organizations. Now, Korea became a well-known leader in IT industry, especially in the paperless trade infrastructure and strategic policies. The one-stop trading system named 'uTradeHub' is operated by a paperless trade service provider, Korea Trade Network(KTNET). uTradeHub includes trade finance and settlement, customs clearance and export and import logistics, improving trading procedures and reducing related expenses. Private-Public joint efforts from Korean government and private sectors which have respectively fulfilled their role and function with market-oriented practical policies and strategies has lead Korea a world leading country in paperless trade. Moreover, Korea expended its efforts to the global areas. Korea has started to activate multi-national paperless trade alliances such as PAA(Pan-Asia e-Commerce Alliance), ASEAL(Asia Europe Alliance for Paperless Trading) as well as established the bilateral cooperative networks with China and Taiwan. The one-stop trading system, uTradeHub should keep close cooperations between nations since trade itself is implemented in a cross-border ways. In the near future, it is expected uTradeHub can achieve best results in the simplification of procedures and cost savings when an international linkage is completely established with international cooperations.

The roll die forming (RDF) process is a new manufacturing technique for producing gear parts such as clutch drum and clutch hub in automotive transmission. In the RDF process, the material is deformed by a roll installed on a die set. Excellent productivity, low forming load and improved dimensional accuracy have quantitatively been shown to be the benefits of the RDF. In this study, the RDF process is applied to manufacture a clutch hub with a gear shaped part. A finite element (FE) analysis was performed in order to investigate the material strain field and dimension of the final product. Based on the result of the FE analysis, a RDF experiment was performed and the dimensional accuracy of the final product was validated. This work demonstrates that RDF is a process capable of producing a sound clutch hub.

In this work, the effect of composite couplings and mass distributions on hub loads of a hingeless rotor in forward flight is investigated. The hingeless composite rotor is idealized as a laminated thin-walled box-beam. The nonclassical effects such as transverse shear and torsion warping are considered In the structural formulation. The nonlinear differential equations of motion are obtained by applying Hamilton’s principle. The blade responses and hub loads are calculated using a finite element formulation both in space and time. The aerodynamic forces acting on the blade are calculated using the quasi-steady strip theory. The theory includes the effects of reversed flow and compressibility. The magnitude of elastic couplings obtained by MSC/NASTRAN is compared with the classical pitch-flap($\delta$$_3$) coupling. It Is observed that the elastic couplings and mass distributions of the blade have a substantial effect on the behavior of $N_{b}$ /rev hub loads. About 40％ hub loads is reduced by tailoring or redistributing the structural properties of the blade.e.

Even in the current age of advanced medicine, the prognosis of malignant peritoneal mesothelioma (MPM) remains abysmal. Molecular mechanisms responsible for the initiation and progression of MPM are still largely not understood. Adopting an integrated bioinformatics approach, this study aims to identify the key genes and pathways responsible for MPM. Genes that are differentially expressed in MPM in comparison with the peritoneum of healthy controls have been identified by analyzing a microarray gene expression dataset. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses of these differentially expressed genes (DEG) were conducted to gain a better insight. A protein-protein interaction (PPI) network of the proteins encoded by the DEGs was constructed using STRING and hub genes were detected analyzing this network. Next, the transcription factors and miRNAs that have possible regulatory roles on the hub genes were detected. Finally, survival analyses based on the hub genes were conducted using the GEPIA2 web server. Six hundred six genes were found to be differentially expressed in MPM; 133 are upregulated and 473 are downregulated. Analyzing the STRING generated PPI network, six dense modules and 12 hub genes were identified. Fifteen transcription factors and 10 miRNAs were identified to have the most extensive regulatory functions on the DEGs. Through bioinformatics analyses, this work provides an insight into the potential genes and pathways involved in MPM.

This thesis examines the problems faced in the electronic trade platform for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's u-TradeHub system are as follows. First, from the technical and legal aspects, to make up for a lack of support systems for spread of users, it is required to promote customized advertising strategies through Ministry of Knowledge Economy and establish a global certification system. Second, document standardization and digitalization should be achieved in advance to make the documents distributed through the e-Trade platform in a seamless manner. Furthermore, an ongoing global network development project should be promoted through the e-Trade platform to achieve standardization. Third, from the operational aspect, it is important to maintain an integrated and systematic relationship with related organizations. Because vertical integration among logistics service providers and GSCM are enabled through the e-Trade platform, it is necessary to standardize global network-based linkage and operating systems.
