This study aims to analyze strategy, one of the predictor variables that have influence on the effectiveness of learning in e-learning environment and to define the factors of e-learning strategies of elementary school students. Preceding studies on face-to-face strategy and e-learning strategy, and existing face-to-face and e-learning strategy test sheets were analyzed. Questions are developed based on the results to make clear the area of leaning strategies used by elementary school students in e-learning environment and to analyze the e-learning strategies of elementary school students. The results from this study are, the e-learning strategies of elementary school students are shown in five areas including strategy for learning activity, strategy for learning attitude, resource use strategy, planning strategy, and overload management strategy. It was found that five strategy areas have explanatory power in the order of strategy for learning activity, strategy for learning attitude, resource use strategy, planning strategy, and overload management strategy.

The e-marketplace is a virtual marketplace where buyers and sellers meet in order to conduct transactions through the intermediation of market-makers. For the success of an e-marketplace, it is crucial for the market-maker to induce both buyers and sellers to make active transactions in it. However, their participation is frequently deterred by potential risk factors caused mainly by the inherent, structural complexity of the e-marketplace. Therefore, it is a critical challenge for the market-maker to identify and manage the transactional risk perceived by both the buyers and sellers. In this paper, we investigate the sources of buyers' and sellers' perceived risks and their mitigating factors in the e-marketplace. Specifically, we derive an analysis framework based on the economic theory of agency relationship. The framework includes four sources of the risks(perceived information asymmetry, fears of seller opportunism, fears of buyer opportunism, and concerns about market-maker's role incompleteness) and five mitigators of the risks(website informativeness, trust in market-maker, trust in seller, product diagnosticity, and social presence). Then, we empirically verify the framework through a case study on four successful e-marketplaces, and provide implications and strategies for the market-maker to effectively manage the transactional risks.

The purpose of this thesis is to contribute to the activation of e-contract service for one stop e-trade by analyzing the problems and its solutions in e-contract service at home and abroad. In order to achieve the purpose of this thesis, case studies are done on e-contract service providers such as CECTRUST service of NTT DATA in Japan and HanCM.com of Haansoft in Korea and user companies such as Taisei Corporation using CECTRUST service and Hyundai Card using HanCM.com. The problems in the e-contract service are the lack of e-contract service providers, rare publicity of e-contract service, limited use of e-contract service at only home, higher pricing for e-contract service, short time management of e-contract documents by service providers, no application of newly developed security technology to e-contract service, unsatisfaction of requirements of e-contract service provider as trusted third party, absence of lower pricing e-contract service by service provider, authorizing key error in electronic signature under recognized authentication system in case of fail in renewal of digital certificate and reproduction of digital certificate. The solutions of these problems are the upbringing of e-contract service providers, broad publicity of e-contract service, development of e-contract service on a global basis, establishment of lower pricing for e-contract service, long time management of e-contract documents by service providers, application of newly developed security technology such as bio technology to e-contract service, satisfaction of requirements of e-contract service provider as trusted third party by designation of recognized e-document repository, development of lower e-contract service by way of application service provider(ASP), introduction of time stamping of e-contract document and signature key value. The limitation of this thesis is that the problems and its solutions could not meet with the broad recognition as they are conferred by intuition because of few e-contract service provider.

In this paper we developed e-Leaning system based on open source software. We selected the Moodle that after compared the open source learning management systems. Moodle is LAMP(Linux, Apache, MySQL, PHP) based course management system (CMS), a software package designed to help educators create quality online courses. One of the main advantages of Moodle over other systems is a strong grounding in social constructionist pedagogy. Also we integrated Moodle and legacy systems such as streaming service, webhard service, and short message service. The system operated during one semester at college using blended learning model. We had obtained showed that the students had almost all scored quite highly as preferred learning environment through COLLES(Constructivist On-Line Learning Environment Survey) and ATTLS(Attitudes to Thinking and Learning Survey). Therefore this research showed that open source based e-Loaming system is stable and possible.

The purpose of this paper is to develop standardized metadata elements of e-mail records with respect to international standards based on analyzing the Australian Government Email Metadata Standard(AGEMS) elements and Korean Records Management Metadata Standard including e-mail records. To achieve the goal, we investigated and analyzed ISO15489 and ISO 23081 which are the international standard related to records and metadata of records. Second, a case study related to the features of e-mail records produced in public institutions in Korea was performed. Third, we made a comparative study of Australian Government Email Metadata Standard(AGEMS). With the results, we proposed mandatory and optional metadata elements for managing e-mail records. Also, the DTD of proposed metadata elements were developed. The proposed metadata elements of e-mail was applied to e-mails which were produced from a administrative information system of a local government in Korea.

Most commercially available collaboration support systems are not proper for small enterprises in a specific area such as small e-design companies, because they are focused on general functionalities, required by most large enterprises. In this paper, we analyze the requirements for improving communication environments of small e-design companies, and propose an advanced communication management tool which reflects those requirements. The communication platform focuses the acknowledgement process by customer and the schedule sharing and management between project members. The proposed system suggest a new research direction which supports the systematic collaboration with external entities such as customers rather than the unsystematic collaboration between internal members, and improves the communication environment of those small e-design companies that are desperately in need of a cost-effective way to carry out projects, and will help in the process of successful projects.

Previous e-financial anomalies analysis and detection technology collects large amounts of electronic financial transaction logs generated from electronic financial business systems into big-data-based storage space. And it detects abnormal transactions in real time using detection rules that analyze transaction pattern profiling of existing customers and various accident transactions. However, deep analysis such as attempts to access e-finance by insiders of financial institutions with large scale of damages and social ripple effects and stealing important information from e-financial users through bypass of internal control environments is not conducted. This paper analyzes the management status of e-financial security programs of financial companies and draws the possibility that they are allies in security control of insiders who exploit vulnerability in management. In order to efficiently respond to this problem, it will present a comprehensive e-financial security management environment linked to insider threat monitoring as well as the existing e-financial transaction detection system.

This paper describes a case study on an enterprise ontology(30) based analysis and representation of the production operation in shipbuilding. The production operation consists of steel fabrication, assembly, election, launching, sea trial and delivery process. We represent and analyze the steel fabrication process and the piping design business of the assembly process among them. First, we build an ontology on concepts of steel fabrication process and the piping design business of assembly process. And then we merge it with the original EO. We represent each process and analyze current state of production process with the merged EO and $Prot{\acute{e}}g{\acute{e}}$ plug-ins. Moreover, we can analyze dependency relations among the workflow elements. Through the case study, we have found the effectiveness of EO in business management and process management in complex heavy industries.
