유비쿼터스 컴퓨팅을 위한 상황 인식 기술은 수집된 컨텍스트 정보를 효과적으로 구조화하여 표현하고, 이러한 컨텍스트 정보를 이용하여 사용자의 의도를 파악한 후, 서비스를 제공하는 기술 등의 연구가 필요하다. 본 논문에서는 상황 인식 컴퓨팅을 위한 프레임워크인 WS-CAM으로 명명된 웹 서비스에 기반한 상황 인식 미들웨어를 제안한다. WS-CAM은 온톨로지 기반의 컨텍스트 모델을 사용하여 다양한 종류의 컨텍스트 정보에 대한 충분한 표현력과 추론 기능을 제공하고, 미들웨어로부터 응용 서비스로의 컨텍스트 정보 전달에 있어서 웹 서비스를 적용하여 미들웨어 독립적인 응용 개발을 이룰 수 있는 구조로 설계한다. 또한, WS-CAM의 유용성을 검증하기 위하여 유비쿼터스 컴퓨팅 환경에 기반을 둔 강의 서비스 시나리오를 기술하고, 웹 서비스 기반의 장점을 보이기 위하여 미들웨어 독립적인 시스템 확장의 예를 보인다. 강의 서비스에 적용한 WS-CAM은 도메인 환경 내의 컨텍스트 정보를 OWL 기반 온톨로지 모델로 효과적으로 표현하였고, 사용자 정의 규칙에 의하여 고수준의 컨텍스트 정보로 추론됨을 확인하였다. 또한, 웹 서비스에 의해 제공되는 다양한 웹 메서드를 통하여 컨텍스트 정보가 응용 서비스에 미들웨어 독립적으로 전달됨을 확인할 수 있었다.

본 논문의 목적은 고객의 소리(Voice of the Customers: VOC)를 활용하여 고객만족서비스를 제공하는데 있다. VOC는 정보서비스를 제공하는 기관들에게 고객만족도 제고와 정보서비스 개선을 위한 의사결정에 영향을 미치는 중요한 정보이다. K연구원은 과학기술분야 정보서비스인 NDSL을 이용하는 고객들의 요구, 건의사항 등의 고객의 소리를 VOC통합관리시스템(VCMS)으로 관리하고 있다. 본 연구는 지난 25개월 간 VOC통합관리시스템에 축적된 VOC 1,738건을 분석하여 정보서비스 개선방안을 제안하였다. 본 논문의 결과는 도서관이나 정보센터가 VOC를 반영한 정보서비스를 제공하고자 할 경우 기초자료로 활용될 수 있을 것으로 기대된다.

While ubiquitous healthcare (u-health) services were expected to propagate along with conventional healthcare services, recent progress indicated rather limited market acceptance. In this paper, we investigated the fundamental causes of why the consumer acceptance level of u-health services has been low. We draw upon innovation adoption theories to analyze the consumer readiness of the typical u-health services. The comparative analysis between innovative u-health services and conventional services was performed using analytic hierarchy process (AHP). Subsequently, policy and business implications including technological breakthrough insights were discussed based on the customer perspective comparative adoption analysis. The propositions captured through this study provide useful insight to further studies on u-health services.

This paper is to introduce recent collaborative activities in agricultural weather information services among institutions in Korea as well as key concepts for understanding agrometeorological services. KMA and RDA have agreed upon the establishment of the Joint Committee for Agrometeorolgy at national level to strengthen the national agrometeorological services in data collection, information production, research, and services to end-users of agrometeorological information in Korea. Several on-going joint projects in agrometeorology by RDA/KMA are introduced in brief. The projects being developed are : Strengthening of the Joint Committee of agrometeorology, Extension of observation network for agricultural weather, Production of the detailed agrometeorological information based on numerical weather forecasts, Development of seasonal and interannual weather forecasts for agricultural applications, Information network system for supporting agrometeorological research, and Improvement of agrometeorological information services at national and regional level. Strengthening of programs for the education and training of agrometeorologists will be impending responsibilities of the government. The government must consider establishment of organizations dedicated to and in charge of national agrometeorological services to end-users. RDA and KMA should play a major role to obtain this goal, based on a close cooperation with universities, scientific societies, and other relevant institutions. If this plan is successful, major infrastructures and services in agrometeorology shall be established in the next 5 years, and we can contribute to regional and global societies through sharing experiences and know-hows.

The first thing to be prioritized is to set the scope of the management system when establishing an information security management system for systematic and effective information security management. It is important to set the scope for an organization's information security goals due to the scope affects the organization's overall information security activities. If the scope is set incorrectly, it might become impossible to protect important services and therefore, the scope of the management system should be determined in consideration of the core business services of the organization. We propose a core service selection model based on the organization's mission-critical service and high risk service in order to determine the effective information security management system scope in this paper. Core service selection criteria include the type of service, contribution to sales, socio-economic impact, and linkage with other services.

Pricing information services, where congestion can threaten the efficient operation of information systems, has been studied in economics and information systems literature, Recent explosion of the Internet ana proliferation of multimedia content over the Internet have rekindled the research interest in designing pricing schedules for differentiated information services, In order for the information system to effectively serve users having heterogeneous needs, pricing rules for discriminated services should be considered. At the same time, when individual users' interest does not align with that of the organization that individual users belong to, organization-wide pricing policy should be devised to improve the value of the services rendered by the system. This paper, using a priority queuing model, addresses the need for such on incentive-compatible pricing for different information services.

Location-based services are a recent concept that integrates a mobile device's location with other information in order to provide added value to a user. Although Location-based Services provide users with comfortable information, it is a complex task to manage and share heterogeneous and numerous data in decentralized environments. In this paper, we propose the Semantic LBS Model as one of the solution to resolve the problem. The Semantic LBS Model is a LBS middleware model that includes an ontology-based data model for LBS POI information and its processing mechanism based on Semantic Web technologies. Our model enables POI information to be described and retrieved over various domain-specific ontologies based on our proposed POIDL ontology. This mechanism provide rich expressiveness, interoperability, flexibility in describing and using information about POls, and it can enhance POI retrieval services.

The present research addresses the system design for building a geospatially-based web services application for mobile users. In recent years, geospatial information(GI) and Geographic Information Systems(GIS) are significant resources in decision-making analyses at various levels of society and activities. Recently, the integration of GIS and web services, called GIS web services, provides the wider implementation of GIS. At the present time, accessing, presenting, and manipulating updatedgeospatial information to locate geo-related facility services are real challenges related to application developers to implement for foot-travelers properly. The present paper investigates how the web services work in a GIS for discovering geo-related facility services such as a restaurant and post office in the user's vicinity. Thus, a prototype, with an architecture consisting of a windows application on the client side as well as facility services and geo-engineon the server side, were designed and implemented with the proposed GIS web services platform. On both the client and server sides, visual studio .Net technology was used. A geo-engine on the server side was also built with ESRI's MapObjects. Following successful implementation of the prototype presented in this study, the mobile user is able to invoke remote web services to assess the location of various facilities such as restaurants. Moreover, the present research demonstratesthat web services are not restricted only to web-based use, but can also be utilized by any web-connected application.
