XML is the most common tool for data processing and data transmission in web applications. Policies are extensively used in all online business solutions and it is recognized that abinary decision such as 'yes/no' for access requests is not enough. In this paper, a method is developed to convert policy rules with provisions and obligations in logic formula formats into XML formats. The primary purpose is to enable security policy programmers to write flexible authorization policies in XML and to implement them easily. General syntaxes are defined to specify information for users, objects and actions in XML formats and an XML DTD is developed to specify authorization rules with these three components. To support various security features such as data transcoding and non-repudiation depending on data in addition to access control based on authorization policies, studies for specifying them in XML policy rules will be performed in the future.

최근 주요 이동통신 사업자, 단말기/칩 제조업체, 콘텐츠 제공업자들 사이에는 모바일 3D 분야가 가장 큰 이슈로 떠오르고 있다. 이러한 환경을 기반으로 모바일 장치에서 3차원 아바타 애니메이션 연구가 진행되고 있다. 이는 아바타의 자연스러운 동작은 사용자에게 아바타가 살아있는 듯한 느낌(Life-likeness)과 사실감(Believability)을 심어주어 보다 친숙한 인터페이스로 활용될 수 있고 이에 따라 채팅이나 온라인 게임 외에도 교육, 쇼핑몰, 비즈니스 등 다양한 분야로 확대되고 있기 때문이다. 하지만 지금까지의 연구는 자연스러운 모션 생성에 집중되어 있을 뿐, 어떻게 쉽게 아바타는 제어할 것 인가에 대한 연구가 적었다. 특히 모바일 환경에서 효율적인 아바타 동작 제어를 위한 연구는 부족하다 할 수 있다. 본 논문에서는 모바일 환경에서 효율적인 아바타 동작을 제어를 위해 스크립트(Script) 기반의 아바타 동작 제어 기법을 제안한다. 모션 생성을 위해 아바타 동작 스크립트(Avatar Motion Script)를 정의하여 아바타 애니메이션의 기록, 재생이 가능하다. 둘째 계층적 스크립트(Multi-Level Script) 기법을 이용하여 적은 양의 데이터만으로도 아바타 동작 제어가 가능하다. 셋째 어느 환경에서도 Motion이 생성, 재생이 가능하한 플랫폼 독립적 구조이다. 넷째, 키 프레임(Key Frame) 기반의 모션을 이용하여 아바타의 상황 상황에 모션이 변하는 동적 동작 생성이 가능하다.

The Internet is taking up every single life of us with a huge speed of growth. If the ideal market called 'perfect competition' in economics will ever come true in this digital world, the sellers won't be able to have monopolistic profits above the marginal cost any more, letting the resource allocation much more efficient. This paper attempts to test whether this theory is true in e-market as well through observing price differences between online and offline retailers of extremely homogeneous products, CDs. Since most results from previous research were supporting the inefficiency of e-market in price level, price adjustment, and especially price dispersion, this article designed the research methodology most carefully. The results of pervious works are partly due to the immaturity of the Internet market or due to the uniqueness of the American CD market, where oligopolistic market players are significantly dominant. The analysis of price data of 20 titles from 20 retailers for five weeks supports that online market is more efficient than offline market with statistical significance in all the three dimensions. We could conclude that the e-market is going much more efficient at least compared to the offline market and the more would it be unless the sellers resist and prevent comparison-shopping.

At a time when the e-commerce market is experiencing accelerated growth, with advancements in information and communications technology (ICT), the problems of distribution of counterfeit products and consumer confusion caused by non-face-to-face purchases have increased. Hence, amid intensifying competition, it has become important for e-commerce companies deliver product information more efficiently, provide differentiated services, and secure credibility for consumers by reducing consumer damage from buying counterfeit products. However, even though consumer confusion and the inadvertent purchase of counterfeit products are intensifying in such a market scenario, there are no services that aim to solve such problems. This study examines the conventional e-commerce industry in South Korea through a political, economic, social, and technological (PEST) analysis, based on in-depth interviews with consumers, to derive the pain and gain points of the industry. As a result, the inherent problems of the e-commerce industry were revealed. Through a service value network perspective, services aimed at resolving such issues were derived, and the e-commerce business ecosystem needed to solve this problem was deduced. The findings revealed that the artificial intelligence-based service support platform has become a major driving force within the e-commerce innovation ecosystem by enabling a new way to create and secure value using ICT. This entails a new exchange mechanism and transaction architecture and a new organizational structure that breaks the barriers between industries.

In a rapidly growing digital economic environment, NFT has emerged as a hot topic in the art field. However, in China, NFT art is developing slowly due to constraints related to China's political economy and socio-cultural situation. Due to strict management and control, the circulation of cryptocurrency is limited, and the level of public awareness and acceptance of NFT art and market maturity are still low. Despite these limitations, this paper predicts that Chinese art creators and market participants can build an online personal art IP model that suits the characteristics of the Chinese market and explores the current status and possibilities.

Initial public offering (IPO) has a legal framework for investor protection, and because there are various quantitative evaluation factors, objective analysis is possible, and various studies have been conducted. In addition, crowdfunding also has several devices to prevent indiscriminate funding as the legal system for investor protection. On the other hand, the blockchain-based cryptocurrency white paper (ICO), which has recently been in the spotlight, has ambiguous legal means and standards to protect investors and lacks quantitative evaluation methods to evaluate ICOs objectively. Therefore, this study collects online-published ICO white papers to detect fraud in ICOs, performs ICO fraud predictions based on BERT, a text embedding technique, and compares them with existing Random Forest machine learning techniques, and shows the possibility on fraud detection. Finally, this study is expected to contribute to the study of ICO fraud detection based on quantitative methods by presenting the possibility of using a quantitative approach using unstructured data to identify frauds in ICOs.

With the development of the Internet and the spread of mobile devices, the online market is growing rapidly. As the number of customers using online shopping malls explodes, research is being conducted on the analysis of usage behavior from customer data, personalized product recommendations, and service development. Thus, this paper seeks to analyze the overall process of online shopping malls through process mining, and to identify the factors that influence users' purchases. The data used are from a large online shopping mall, and R was the analysis tool. The results show that customer activity was most prominent in categories with event elements, such as unconventional discounts and monthly giveaway events. On the other hand, searches, logins, and campaign activity were found to be less relevant than their importance. Those are very important, because they can provide clues to a customer's information and needs. Therefore, it is necessary to refine the recommendations from related search words, and to manage activity, such as coupons provided when customers log in. In addition to the previous discussion, this paper proposes various business strategies to enhance the competitiveness of online shopping malls and to increase profits.

Unlike the traditional bricks-and-mortar marketplace, the online environment includes several distinct factors that influence Web site trust. As consumers become more savvy about the Internet, the author contends they will insist on doing business with web companies they trust. This study examines 1) how Web site trust is affected by the following web purchase-related factors: security, privacy, brand name, word-of-mouth, good online experience, and quality of information, and 2) how it influences outcomes. Unlike Urban and colleagues' study (2000), the author argues that not all e-trust bUilding programs guarantee success in building Web site trust. In addition to the mechanism depending on a program, building e-brand trust requires a systematic relationship between a consumer and a particular web site. The findings show that Web site trust does not build one or two components but are established by the interrelationships of complex components. By carefully investigating these variables in formulating marketing strategies, marketers can cultivate brand loyalty and gain a formidable competitive edge.
