Recently, as mobile paradigms such as telematics or LBS (Location Based Service) have been being more diverse and mobile devices such as PDA (Personal Digital Assistance) or several telematics terminals have been being used more widely, mobile services, for example, mobile geographic information service have been being put more importance by people. In this paper, we propose to adopt S/W and data streaming mechanism as a method to improve performance of mobile geographic information service which is a representative of mobile services based on client-server architecture. The show the effectiveness of proposed methods, we design and implement S/W streaming prototype system and sample mobile geographic information service to be executed on the S/W streaming system.

본 연구는 모바일 부동산 서비스의 정보 품질과 허위매물의 개선방안을 검색 필터 서비스를 통해 성장 가능할 방안을 제공하였다. 현재 활발하게 사용 중인 각국의 대표적인 모바일 부동산 앱의 사례를 비교했으며 부동산 정보 탐색 시 가장 먼저 필요한 검색 필터 13개를 채택하여 사용성과 서비스 상태를 분석했다. 그 결과 모바일 부동산 서비스 정의 맞게 사용자들이 언제 어디서나 유기적으로 신속하며 신뢰성 있는 정보를 받기 위해서는 수준 높은 검색 필터 서비스 공급이 정보품질 개선을 위해 필수적이다. 결국, 허위매물에 대한 사후적인 대책 마련보다는 사전 검수가 야기되며 사용자의 니즈에 충족되어 보다 개선된 검색 필터 서비스를 제공하여 모바일 부동산 중개 서비스의 정의에 맞게 시간과 공간에 제약받지 않고 신뢰할 수 있는 정보품질의 서비스를 공급하는 것이 허위매물의 피해자를 사전적으로 예방하는 것이라 말할 수 있다.

WAP을 이용하는 무선인터넷 서비스의 경우, WAP Gateway를 통하여 http 프로토콜과 연동하여 통신한다. 따라서 사용자들은 무선 인터넷 서비스 비용 증가와 함께 WAP Gateway에서 사용자의 정보를 감시할수 있기 때문에 내적 보안의 취약성이 대두되었다. 이러한 문제점들을 해결하기 위하여 플랫폼독립적이고, 비용감소, 좀더 강화된 보안성과 다운로드가능한 어플리케이션을 위하여 자바언어을 사용하여소켓통신을 이용하여 유.무선 메시징 시스템(WWMS)은 PC 클라이언트와 Moblie 클라이언트, Mobile 클라이언트와 Mobile 클라이언트, 각각에서 실시간으로 통신할 수있다. 본 논문에서는 J2ME를 이용한 멀티 플랫폼 유.무선 메시징 시스템을 설계하고 구현함으로써, 향후 다양한 Mobile 응용프로그램들을 개발하는데 기초가 될것이다.

The service industry has been acknowledged as a critical part of mobile banking services in recent years. This study examines the impact of e-service quality and loyalty on the intention to use and use behavior of mobile banking services in Mongolia, a Central Asian country. As a result, based on past research, a conceptual model was suggested. This study comprises 209 completed questionnaires from young Mongolians who own a bank account and a smartphone. The data was collected based on convenience sampling, and it was analyzed with SmartPLS software using a partial least squares-structural equation modeling (PLS-SEM) technique. The findings indicate that system quality, interface design, and security assurance have a significant positive impact on service quality; service quality has a positive impact on loyalty. Moreover, the results reveal that service quality and loyalty have a significant influence on the intention to use mobile banking services. The findings of this study suggest that local or international banks and financial institutions in Mongolia should consider system quality, interface design, and security concerns as key successors to building perceived security quality to retain current mobile banking users and attract new customers.

In the case of mobile internet service using WAP, It was connected to http protocol using WAP Gateway. So, Users take increased cost of mobile internet service. and it was generated inner security problem because it watched user information in the WAP Gateway. To solve this problem we use java language. Which is independant of platform and low cost and intensely security and downloadable application. Additional, Using socket connection, Multi Messaging System(MMS) will connect real time between PC-Client and Mobile-Client, Mobile-Client and Mobile-Client, and so on. In this paper, as design and implementation o( multi messaging used SK-VM based on .12ME, It will be foundation to develop various mobile application in the future.

Recently, the internet and mobile telecommunication is proliferating rapidly in the whole world. In accordance with this, people have growing desire to use the internet without the limitation of the space; as a result, the mobile internet users are incredibly increased. However, the established study about the mobile internet emphasize the technical aspects. Therefore, this studies finds the significant factors that affect the use of mobile internet service. This study suggests the enterprises getting the service direction which they will use as a strategy in the future. In order to do this, the study examines the factors which can affect the using of the mobile internet service and analyzes the established study about the quality of the information system and the internet service. The result of the survey shows that the factors affecting the use of the mobile internet service are the stability of the system, the convenience of the system, and the response of the service. It also appears that the satisfaction of the mobile internet service affects the attention of the users to using the mobile internet service. The five theories are selected from the ten creative theories, these explain that it is a little unreasonable to design the model which is related to the prior study of the information systems. It will be more deeply scrutinized to analyze the effect of the satisfaction and the utilization of the users through the quality of the information contents.

최근 정보기술 발전과 컴퓨터의 고성능화에 따라 인터넷과 지리정보 시스템(GIS: Geographic Information System)을 연동하여 많은 웹사이트에서 지도정보 및 POI(Point of Interest)서비스를 제공하고 있다. 이러한 Web GIS는 시스템 구축이나 서비스 제공방법, 지도표현 형식에 있어 특정 시스템이나 환경에 의존적이며 제약이 많이 있다. 또한 무선인터넷의 급속한 발전으로 이동 환경에서 현재 위치정보를 적용한 실시간 서비스를 제공받기 원하는 사용자가 급증하고 있는 시점에서 이러한 서비스는 PDA와 같은 이동클라이언트에 LBS(Location Based Service)로 제공될 수 있어야한다. 본 논문에서는 국립지리원의 표준 지도형식인 DXF 수치지도를 이용하여 모바일 웹 서비스가 가능한 GIS를 구축하였다. 그리고 이를 OGC(OpenGIS Consortium)에서 권고한 벡터 방식의 SVG(Scalable Vector Graphics) 포맷의 지도로 표현하고, XML 웹 서비스를 이용한 개방형 서비스로 제공하였다. 또한 이동클라이언트인 PDA에 GPS수신기를 확장하여 이동환경에서 위치정보를 획득하여 모바일을 위한 실시간 위치기반 웹지도 서비스를 설계하고 서버기반 G15 컴퓨팅 환경을 실용적으로 구현하였다.

Through numerous mobile device technology advances, various multimedia contents is moving towards mobile devices from existing personal computer (PC). These paradigm has emerged taking into account these idea, the so-called N-Screen, N-Screen is user-centric service to provide running and sharing on everywhere via advanced smart system in C-P-N-T (Content, Platform, Network, Terminal). Therefore we must provide securing of various contents, openended platform, and user-centric service for efficient N-Screen service. For These characteristic of N-Screen, this paper propose design and implementation of user location-based N-Screen service system. The proposed system realize user location through user's smart phone and offer automatic streaming service to user. And also, we provide web service-based extended N-Screen service. Thus, user can access various device, such as laptop, tablet, and mobile device.

In this paper, we proposed the next generation mobile convergence service business model creation methodology. In order to establish such a business model creation methodology framework, we first introduce the service model based on our previous research results on next generation mobile convergence services. The service model contains several components such as infrastructures, operations, and provision of services that are indispensible for providing the next generation mobile services. Finally, by adding service and value flows to the developed service model, we propose the next generation mobile services business model creation methodology. To achieve this objective, we first derive necessary components of business model including actors, their relationships, and roles. In addition, we propose service composition methodology for creating new mobile services and its corresponding business models.
