The goal of this study is to find ways to improve the open access publication support service platform through the usability evaluation of the publishing manager interface among the AccessON journal repository interfaces, which is an open access publication support service platform. Various documents and cases related to open access publishing and usability evaluation in order to answer three research questions: collection of user experience responses of interface, extraction of issues and improvement points, and analysis and derivation of suggestions for other open access publication support service platforms. Responses to the experience of using the publishing manager interface were collected through surveys and focus group interviews. Combining this, it was possible to present the results of the usability evaluation of the AccessON journal repository interface through various numerical information. The results of the usability evaluation made it possible to propose issues and improvements to the AccessON journal repository manager interface, and finally, it was possible to derive suggestions for the open access academic publishing support service platform to be developed later.

The control center of an urban railway operator provides railway users with various information on railway use through a 1:N same-time broadcasting system. However, the facilities of the broadcasting system are aging, exposing many limitations in meeting the needs of urban railway users who have become familiar with mobile services. To overcome these challenges, this study analyzed the mobile-based same-time broadcasting services using location information of urban railway users and the requirements of various stakeholders (urban railway users, an operator, and external service providers, etc.) to suggest optimal service models and physical structures. Through this study, it aims to secure safer operations of urban railway as well as to improve better disaster responses through rapid and efficient spread of the situation in case of disaster.

웹기반 쇼핑시스템(Web-Based Shopping Systems: WBSS)이 매우 급속한 속도로 글로벌 전자상거래 환경에서 확산되고 있다. 웹기반 쇼핑시스템은 인터넷에 기반하여 제품(product)나 정보(Information) 그리고 서비스(service)에 대한 상거래 행위나 활동이 이루어 질 수 있도록 지원하는 시스템이다. 아마존(amazon.com)과 같은 닷컴기업들은 웹기반 쇼핑시스템을 성공적으로 운영하고 있는 대표적인 예에 해당된다. 아마존(amazon.com)의 예와 같이 기업들이 웹기반 쇼핑시스템을 도입함으로써 이전의 상거래와는 전혀 다른 유형의 사업(business)을 전개할 수 있다. 따라서 본 연구는 디지털 경제의 핵심적 동인(enabler)인 웹기반 쇼핑에 관련된 연구를 수행하는 연구자들 뿐만 아니라, 웹기반 쇼핑시스템의 성공적 구현 및 운영에 관심있는 기업인들에게 효과적인 가이드라인을 제공해 줄 것이다. 또한 전자상거래 (electronic commerce)에 관련된 기존 연구들은 정보통신기술(Information Communication Technology: ICT)의 역할을 과대평가하거나 혹은 과소평가하는 경향이 있다. 예를 들면 사회과학의 어떤 연구에서는 기술(technology)의 무분별한 수용에 대한 회의론이 제기되고 있고, 공학과 컴퓨터 분야의 연구에서는 기술적 측면에만 집중하여 연구가 수행되는 경향이 있다. 위와 같이 어느 한쪽에 편협된 시각에 근거하여 웹기반 쇼핑시스템과 같은 새로운 정보통신기술의 확산현상을 적절하게 설명하기에는 한계가 있는 것 같다. 따라서 본 연구에서는 웹기반 쇼핑시스템의 확산에 관련된 균형된 분석을 수행하기 위하여 경영(management)과 기술 (technology)을 조화롭게 고려한 관점에서 연구를 수행하고자 한다. 즉, 본 논문에서는 기술적 측면(technical aspect)과 경영적 측면(management aspect)을 동시에 고려하여 웹기반 쇼핑시스템의 주요만 특성을 살펴보고, 향후 정보통신 기술(ICT)의 확산에 관한 연구에서 두 가지 관점의 통합적 중요성에 대하여 강조하고자 한다. 그에 덧붙여 웹기반 쇼핑시스템과 다른 정보시스템을 비교하여 전자상거래 환경에서 웹기반 쇼핑시스템의 주요만 특성들이 두가지 연구관점에서 어떻게 개념화 될 수 있는지를 고찰하고자 한다. 이러만 분석에 기반하여 본 연구에서는 기술적 측면과 경영적인 측면을 동시에 고려한 웹기반 쇼핑시스템의 특성을 제시하고자 한다. 결론적으로 본 연구의 목적은 본 논문에서 적용한 기술(technical)과 경영(management)의 조화로운 연구관점이 향후 정보통신 기술이나 시스템, 그리고 전자상거래에 관련된 일련의 연구에 적응되어 보다 균형잡힌 논의와 분석이 이루어 질 수 있는 시발점이 되길 기대한다.

Web streaming environment need a suitable video playback service technique, a streaming technique for real-time delivery and an efficient control technique due to its limited environment. In this paper, we propose an effective control technique for real-time media stream playback as a connection technique between the high-quality media player and web browser based on Linux environment. The proposed stream control technique presents control data through 050 on media playback screen of web browser, and process the user's input data. It acts GUI-independently, and is designed considering addition and extension for control data.

Mobile payment service is a new innovating technology in the micro payment industry. Although it emerged only one or two years a9o in Korea, it is now highly used and prospered by many online companies. Traditional studies concerning the electronic payment system are usually about the payment process itself, so they stressed the security or the robustness of the process. The study from the angle of behavioral science seldom exists. This article describes the phenomenon of technology adoption with a particular focus on telephone Payment service. The article identifies which characteristic of the telephone payment service affects to the user status (user, non-users). To do this, this article mainly used Roger's Technology Acceptance Model and some characteristics are added to the model. The most important perceptual characteristic that affects to the user status was not security, but ease of use-the telephone payment service had to enhance continuously for the competitive advantage over the other payment service. Observability and convenience are also noted as important.

With the advancement of Artificial Intelligence (AI) technologies, the provision of data-driven AI services that enable automation and intelligence is increasing across industries, raising concerns about the AI security risks that may arise from the use of AI. Accordingly, Foreign countries recognize the need and importance of AI regulation and are focusing on developing related policies and regulations. This movement is also happening in Korea, and AI regulations have not been specified, so it is necessary to compare and analyze existing policy proposals or guidelines to derive common factors and identify complementary points, and discuss the direction of domestic AI regulation. In this paper, we investigate AI security risks that may arise in the AI life cycle and derive six points to be considered in establishing domestic AI regulations through analysis of each risk. Based on this, we analyze AI policy proposals and recommendations in Korea and validate additional issues. In addition, based on a review of the main content of AI laws in the US and EU and the analysis of this paper, we propose measures to improve domestic guidelines and policies in the field of AI.

Patent information has a great value of industrial information as well as technical information. However, Korean patent information loses the effectiveness by the lack of description rule and requires much additional efforts to use them in variety. In this paper, some examples of the studies on the problems in databases were introduced and patent application(from Jan. 2008 to Oct. 2008) data retrieved from information service system of KISTI(Korea Institute of Science and Technology Information) and KIPI(Korea Institute of Patent Information) was surveyed.

As Mobile Internet gets more popular, the switchover of E-Commerce to M-Commerce gets faster and many service providers offer diverse M-Commerce service by using mobile technology. Also, as M-Commerce makes rapid progress, the security protocol gets more widely recognized for its significance. In particular, WAKE(Wireless Authentication and Key Establishment) protocol carried out wirelessly is of great importance, since the user and service provider must get through to carry out the M-Commerce. Key recovery method is a part of the key management in order to provide an emergency recovery of key whenever necessary, like when the user lost the key or the cryptosystem was illegally used. The ASPeCT project first tried to support the key recovery function in WAKE Protocol Since then, a variety of WAKE Key Recovery protocols have been proposed. In this thesis, problems of WAKE Key Recovery protocols proposed so far are analyzed and new WAKE Key Recovery protocol is suggested to solve those problems.

WiBro (Wireless Broadband) service, developed in Korea, can provide the host mobility while its users hang around within the subnet. Next-generation Internet protocols, IPv6 and Mobile IPv6 (MIPv6), provide a plenty of addresses to the nodes and enable the handover between different subnets. However, MIPv6 is not enough to support a real time service such as VoIP (Voice over IP) due to the long latency, and it is necessary to develop an enhanced handover mechanism which is optimized to the WiBro networks. In this paper, we suggest an improved fast handover mechanism while the mobile node moves around WiBro networks. The proposal is based on Fast Mobile IPv6 (FMIPv6) which is the representative protocol for fast handover, and reduces the handover latency by the close interaction between the link layer (WiBro MAC) and IP layer (FMIPv6). Finally, we analyze the performance of proposed mechanism through the mathematical analysis.
