Moblie games are getting popular in that more mobile handsets are available. The mobile phone is expected to be the dominant platform the way the PC turned out to be the dominant platform of desktop computing. Ubiquity enables the mobile phone users interact socially with other users. Mobile game developers are now competing globally on the Apple Appstore, where any developers in the world are able to publish their own games easily. This study reviews the case of Gamevil, one of the leading mobile game service providers, from its foundation to the current global competition in order to draw implications for mobile game industry.

With the development of enabling technologies such as wireless networking and various types of hand held-mobile devices, Mobile intelligent agent has been widely applied to various fields. Different views on capabilities, advantages, and disadvantages of mobile intelligent agent providing an ubiquitous access are brought by field researchers and practitioners recently. The purpose of this paper is thus to provide the discussion of the comtemporary development of mobile intelligent agent in the contexts of the Infosphere, focusing especially on developing and nurturing the future research grounds such as information scalability, and information security. The results of this study would improve the applications of mobile intelligent agents in web transaction, especially mobile business surroundings where many interest groups have to adjust their point of issues rapidly due to the changing business environment, i.e., customer's change the order item in web.

This paper investigated a gate driver circuit with amorphous silicon for mobile TFT-LCD. In the conventional circuit, the fluctuation of the off-state voltage causes the fluctuation of gate line voltages in the panel and then image quality becomes worse. Newly designed gate driver circuit with dynamic switching inverter and carry out signal reduce the fluctuation of the off-state voltage because dynamic switching inverter is holding the off-state voltage and the delay of carry signal is reduced. The simulation results show that the proposed a-Si:H gate driver has low noise and high stability compared with the conventional one.

East Asian region, specifically China, Japan, and Korea, is considered as an area of advanced mobile handsets and mobile services. The well-established infrastructure of this region is well known due to rapid introduction of diverse feature-equipped handsets and advanced capabilities of mobile network operators. However, the status of mobile business has rarely been dealt with in previous studies. In this paper, we compare mobile value chains among these three countries. China has adopted open platform for mobile data services while Korea and Japan's mobile network operators control mobile portals for accessing diverse contents and services. We also discuss some possible reasons for the differences among the three countries in terms of value chain structures.

It is expected that the next generation mobile communication system will be a service-driven developed system capable to realize the human-centric mobile convergence services. and it is different from the technology-driven development approach of the second and the third generation mobile communication systems. As a preliminary research work on such service-driven system development approach for the next generation mobile communication system. we developed the scenario based service analysis process (2SAP) framework to derive core service technologies and functionalities. In this paper. we propose the next generation mobile convergence service business model creation methodology based on research results of the 2SAP framework. To achieve this goal, we first establish a service model contains several components such as infrastructures. operations. and provision of services that are indispensible for providing next generation mobile services. Then, the next generation mobile services and its corresponding business models can be created by adding service and value flows to the developed service model after defining necessary components of business model including actors, their relationships, and roles.

최근 급격한 기술 발전 추세에 따라 스마트 폰, 태블릿 등과 같은 모바일 기기들이 최신의 통신기술에 접목되면서 다양한 분야에서 우리 삶을 혁명적으로 바꿔 놓고 있다. 특히, 스마트 폰의 응용 서비스가 매우 강조되면서 스마트 폰은 스마트 폰을 이용한 모바일 비즈니스 프로세스에서 중요한 역할을 담당하게 되었다. 이러한 디지털 융복합 시대에서는 모바일 기기들의 이동성으로 인해 새로운 비즈니스 모델이 탄생하고 있다. 스마트 폰의 위치를 기반으로 사용자 주변 지역 또는 상점의 관련 정보를 제공해 줄 수 있다. 또한 스마트 폰의 사용자 프로파일이 광고주와 제품 판매자에게 제공되고 광고주는 사용자의 프로파일을 기반으로 사용자가 관심을 가질 제품들을 광고한다. 사용자는 최저 가격비교, 관련 상품이나 유사 상품 등의 정보를 제공 받을 수도 있다. 본 연구에서는 이와 같은 시나리오를 기반으로 새로운 비즈니스 모델을 제안하고 이를 실현하기 위해 필요한 기술적 문제가 없는지를 검토하였다.

국내 모바일 인터넷 서비스 시장은 매우 빠르게 성장하고 있다. 본 논문은 국내 모바일 인터넷 서비스의 현황을 고찰하고, 신방, 방송, 인터넷 등 주요 미디어 기업이 제공하는 모바일 콘텐츠 서비스 유형을 분석하였다. 연구결과 미디어 기업들은 일반적으로 모바일을 통해 뉴스와 정보 유형들을 무료로 제공하며, 새로운 미디어 영역에서 시장 경쟁력을 유지할 새로운 비즈니스 모델을 개발하려고 노력하고 있다. 미디어 기업의 모바일 콘텐츠 영역은 아직 분명한 콘텐츠 비즈니스 모델의 부족으로 초기 단계에 있다. 소비자의 욕구를 만족시키며 시장에서의 경쟁력을 유지하기 위해서는 미디어 기업들이 향후 새로운 비즈니스 모델을 지속적으로 개발해야 하고, 모바일 서비스 시장의 장애물을 줄여나가기 위해서 시장의 다른 참여자들과 서로 협력해야 한다.

Mobile business, noticed as a constructive alternative for e-commerce and e-business, has been diversely defined and conceptualized. This study develops a comprehensive framework for the sake of clearing such a havoc of conceptual deluge. The framework for the comprehensive understanding of e-business (including m-business) consists of two dimensions： connectivity and mobility. These two dimensions represent to overcome the constraints of time and place in business transactions, respectively. Various cases for each combination of these two components are explained for clear understanding of this framework. By this framework, we can understand the value that Location-Based Service (LBS) brings anew to e-business services.
