The research empirically analyzes the impact of technological regime of game engine upon game development performance. The results indicate that, first, technological regime of game engine determines game's genre distribution. Secondly, user friendly game engine regime(modular, generic and integrated API engine) induces higher genre diversity and lower genre concentration ratios. Thirdly, user friendly game engine regime(modular, generic and integrated API engine) is becoming more applied recently. Fourthly, innovation types and price types of game engine do not influence upon game engine trades. Those results point out that game engine's technological regime influences directly game development application and user friendly regime is increasingly more standardized.

Existing internet auction systems have adopted the form which gives a win to the auction bidder who proposes the top bid price for the goods posted on the auction board. But they haven't been satisfying the automatical one-step processing for user’s convenience because they must require continuous care of user for bidding and checking as well as neglecting the convenience of user interface while participating in the electronic bidding system. The agent push mail to a auctioneer information that able to get how much profit as calculate duration time and start price with bidding history stored database. So, this thesis propose a multi-agent system in internet auction that generate the highest margin for auctioneer’s goods.

법률행위로 인한 부동산물권변동의 성립요건인 부동산등기는 부동산이라는 재산의 물권변동관계를 등록하는 매우 중요한 업무이고, 또한 부동산과 관련한 권리관계와 상황이 실체관계와 일치하도록 명확히 공시하는 것을 목적으로 하는 제도이다. 이러한 등기업무가 그동안 종이등기부에 기초한 수작업인 관계로 부동산 거래가 증가할 경우 처리기간의 장기화와 천재지변에 따른 문서훼손 등을 막기 위한 대처방안이 절실히 요구되는 시기에 정보통신기술의 급격한 발전과 함께 사법부의 정보화 추진 노력으로 2002년 전자등기업무 시스템이 구축되면서 종이등기부가 전자등기부로 전환되었다. 그러나 세계적으로도 큰 사업이었고, 공간적 제약의 최소화와 대국민 서비스의 품질의 극대화 차원에서 성공적으로 잘 운영되고 있는 부동산전자등기 업무에 있어서 다양한 정보를 제공받지 못한 관계로 인한 손해, 등기공신력과 전자등기신청 시 공인인증서 보안문제 등이 대두되고 있다. 따라서 본 연구에서는 문제점을 파악하고, 철저한 보안을 통한 위험성을 차단하고 국민들에게 신뢰와 편의성이 제공될 수 있는 효율적인 개선방안을 제시하였다.

The EU, the United Kingdom and South Korea are actively pursuing open banking to open financial information to fintech companies for financial structure reform and convenience of financial consumers. As open banking is gradually activated, the importance of stability and protecting users of open banking will increase. In particular, Korea has an electronic financial transaction law that has been in effect since 2007 to secure the stability and reliability of electronic financial transactions, but it is difficult to apply to participating organizations in open banking, so there is a risk of preventing security accidents and weakening user protection in open banking. Therefore, this paper examines the foreign legal system of open banking and analyzes the structure and characteristics of domestic open banking and suggests the ways to improve regulations necessary to strengthen open banking stability and user protection.

As a new environment, the Internet proposes to us the innovative change of our life. With difficulty, we can go after the Internet's potentiality and the growth speed of technology. In the new stream of innovation technology, we can probably feel the fear of tremendous changes, the reverse, also hope to get the opportunity that come out of Internet world. EC(Electronic Commerce) that out of the evolution of Internet technology gets a coporation changes to survive in 21st century. So the corporation must set the strategy to fit a Internet focused society. As one of them, a virtual store is opened on the Internet. Recently, there has been much attention to the Internet shopping mall as a new distribution channel and marketing tool. This study analyzed that the system environment, perceived product risk, easy of order, perceived security risk would have impact on the customer satisfaction in Electronic Commerce. The Purpose of this study is to develope the concept of the determinants of customer satisfaction and to test a theoretical framework that attempts to explain how the perception of satisfaction in Electronic Commerce. The proposed hypotheses were tested internet shopping mall users and the study results show all hypotheses are supported.

In the fintech environment, ensuring secure financial transactions with smartphones requires authenticating the device owner. Smartphone authentication techniques encompass a variety of approaches, such as passwords, biometrics, SMS authentication, and more. Among these, password-based authentication is commonly used and highly convenient for user authentication. Although it is a simple authentication mechanism, it is susceptible to eavesdropping and keylogging attacks, alongside other threats. Security keypads have been proposed to address vulnerabilities in password input on smartphones. One such innovation is a group keypad, resistant to attacks that guess characters based on touch location. However, improvements are needed for user convenience. In this study, we aim to propose a method that enhances convenience while being resistant to eavesdropping and recording attacks on the existing group keypad. The proposed method uses new signs to allow users to verify instead of the last character confirmation easily and employs dragging-to-touch for blocking recording attacks. We suggest diverse positioning methods tailored for domestic users, improving efficiency and security in password input compared to existing methods.

Recently, way of Electronic Commerce is changing with increment of Internet users. In the previous way of commerce, users used to search for information by themselves. However, for user's convience, it can be done for users from one site. Mobile in order to provide users with such service. By the mobile agent-based Electronic Commerce system, users can get information from one site, and service companies can provide various and useful information to users. This is very important for construction of reliable Electronic Commerce environment, However, in generally used mobile agent-based platforms, the user should know URL information. and it is based on search engines. And as user's requirement levels become higher, they want to be provided with integrated and summarized service. In this paper, we implement product-trading system by applying mobile agent concept in order to satisfy user's requirement of getting required information from one site with minimal mouse click. For implementing the product trading system, E-speak, which is a platform for E-Service, is used And contents are saved as XML documents and data are shared based on these documents.
