최근 모바일 기기는 거의 모든 사람들에 의해 사용되고 있는데, 이는 모바일 단말기가 휴대하기에 편리하고 아울러 모바일 네트워크의 성능이 향상되었기 때문이다. 이에 따라 휴대폰 상에서 실행 가능한 응용의 종류가 다양해지면서 대용량 소프트웨어 실행에 대한 필요성이 대두되었고, 이를 위해 Mobile-JPVM 같은 휴대폰 클러스터 컴퓨팅 라이브러리도 등장하였다. 본 논문에서는 Mobile-JPVM을 이용하여 실시간 Animated GIF 파일 생성기와 휴대폰용 Animated GIF 뷰어를 구현하였다. 아울러, 개발된 소프트웨어를 KTF 휴대폰에 탑재하여 에뮬레이터가 아닌 실제 환경에서 실행될 수 있음도 보였다. 개발된 실시간 Animated GIF 생성기와 휴대폰용 뷰어는 모바일 패션 데이터 광고 서비스에 활용될 수 있다.

Mobile banking service has emerged as an important profit source for both banks and mobile phone service companies. However, the growth of the mobile banking service is behind the expectation of banks and mobile phone companies. One plausible explanation for this laggard diffusion of mobile banking may be the lack of consumers' initial trust on the service. Therefore, this study investigates the critical factors in building trust and intention to use mobile banking services. Our research results show that propensity-to-trust, structural assurance, and relative advantages of services have significant impacts on consumers' initial trust in mobile banking service Furthermore, initial trust in mobile banking service is a critical factor for adopting mobile banking services Contrary to our expectation, however, reputation of banks and mobile phone companies are not significant in attracting consumers to mobile banking services.

The rapid growth of mobile communication technology has provided the expansion of mobile internet services, particularly mobile realtime transaction takes much weight among mobile fields. There is an increasing demand for various mobile applications to process transactions in a mobile computing fields. Thus, During transmission in wireless networks a base station failure inevitably causes data loss of the base station buffer. It is required to compensate the loss for communication. The existing methods for a base station failure are not adequate because they all suffer from too much overhead and resolve only the link failure. In this paper, we study an efficient recovry systems for a mobile DBMS. We propose SLL (Segment Log List) that enables the mobile host to compensate data loss efficiently in the case of base station failure. In SLL, a base station deliveries an output information of data cells to a mobile host. when a base station fails, the mobile host can retransmit just next data cells. We also prove the efficiency of new method.

There found limitations of mobile advertising researches in methodology, theory building, and research implication. Existing researches were basic and some exploratory studies on mobile advertising and its effects. Especially, there was not a systematic typology research on mobile advertising. This paper tried to develop a systematic and empirical typology of mobile advertising and show proper advertising cases. We classified mobile advertising using mobile channels and methods (Text, Icon, Media, and Contents), Also we used advertising effects like information offering, leading transaction and response, and channel connection in classification of mobile advertising. Finally we suggested mobile advertising cases based on this typology and analysed the performance of moile advertising.

IPv4/IPv6 통신 서비스를 위한 변환기는 호스트의 변경 없이 IPv6 호스트와 IPv4 호스트간의 통신을 지원해 준다. 그러나 호스트가 모바일 노드일 경우 삼각형 라우팅 문제가 발생한다. Mobile IPv4 모바일 노드가 이동할 경우 홈 에이전트와 IPv6의 CN(Correspondent Node)에게 반드시 이동 정보를 보내 주어야 하지만 현재 NAT-PT는 IPv4와 IPv6의 이동성 헤더인 모바일 IPv4/Mobile IPv6의 헤더 변환은 지원해 주지 않기 때문에 삼각형 라우팅 문제가 발생하여 Mobile IPv4와 Mobile IPv6간에 비효율적인 통신을 일으킨다. 본 논문에서는 Mobile IPv4와 Mobile IPv6 통신에서 발생하는 삼각형 라우팅 문제를 해결하기 위한 모바일 헤더 변환 메커니즘을 제안하였다.

Today, the proliferation of smart-phones and other mobile devices is bringing many changes to people's daily lives. Recently, the mobile shopping market has grown rapidly and has become a center of distribution. Furthermore, the consumer mobile fashion market is expected to expand and mobile fashion consumers' shopping tendencies will gradually become segmented. Differentiated marketing strategies for mobile fashion companies are to become essential. This study intends to understand the propensity of mobile fashion shopping and the importance of fashion app attributes, and their impact on mobile fashion shopping customer satisfaction and loyalty. The research aims to identify shopping trends and buying behaviors of mobile fashion consumers, find ways to increase mobile fashion shopping purchases, and help develop the mobile fashion market. The results of this study are summarized as follows. First, the compilation and the economics of the mobile fashion shopping propensity factors were shown to have a significant impact on product information, product reviews, and service quality, which are in turn important factors for fashion app attributes, whereas convenience only had a significant impact on service quality. Second, product information and service quality, which are also important factors for fashion app attributes, have a significant impact on mobile fashion shopping. Third, customer satisfaction concerning mobile fashion shopping has a significant impact on loyalty. Mobile fashion shopping customer satisfaction increases loyalty. Increasing the satisfaction and loyalty of mobile fashion shopping will lead to increased sales using mobile fashion shopping apps(Site) and become apparent in the results of mobile fashion companies. Therefore, various efforts by mobile fashion companies will be needed to satisfy their customers.

The mobile market has introduced unprecedented shopping opportunities to customers and is expected to grow rapidly over time. However, little is known about how customers make purchase decisions in the mobile market. The purpose of this study is to investigate the drivers of mobile VOD purchases and to deliver valuable insights to mobile business operators. We focus on the purchase of VOD contents that have to be purchased and consumed using mobile devices and examine how individual-level purchase decisions are determined by three factors: perceived usefulness, usage behavior, and privacy concern. We obtained the panel data from a leading market research company that contains the mobile logs and survey results. Our main results suggest the followings. First, the perceived usefulness affects customers' mobile VOD contents purchases positively whereas the usage behavior exerts no influence on mobile contents purchases. Moreover, the privacy concern lowers the positive effect of perceived usefulness on mobile content purchases; however, it enhances the effect of the usage behavior on mobile contents purchases. These empirical findings indicate that mobile business operators should pay more attention to potential differences in perception and behavior using mobile devices and keep in mind that the privacy concern plays an additional key role in driving mobile contents purchases.

Mobile technologies and services have become one of the inevitable parts of people's lives and mobile businesses have also been widespread. Popular mobile internet services through cell phones have made people in the financial industry consider that 'mobile' is promising. Nevertheless, there have been little studies of mobile services in the financial industry and most of the studies have been concentrated on internet services. The main purpose of this study is to investigate on the determinants of intention to use mobile banking. To achieve the goal, based on the theoretical backgrounds of the Technology Acceptance Model(TAM). Survey questionnaires were distributed via post & email to 500 users who have been experiences with cell phone and have an account. Out of 291 responded questionnaires, 275 data sets were available for statistical analysis with SPSS 10.1. Research hypotheses are analyzed by LISREL 8.30. Factor analysis identified seven external factors : (1) convenience, (2) cost, (3) unusefulness, (4) riskiness, (5) personal innovativeness (6) users' self-efficacy (7) experience of mobile services. Results of this study show that convenience, unusefulness, riskiness, personal innovativeness and experience of mobile services have significant effects on intention to use mobile banking . Much of the previous researches have dealt with service provider only and have focused on mobile internet. In this regard, when it comes to a viewpoint that regards the mobile banking sector as a new sector of mobile businesses. This study may provide a guideline to activate of mobile banking acceptance.
