Much work on innovation has focused on the manufacturing sector. In this paper, we propose a framework for analyzing innovation in services centred on capability and technology integration. We illustrate the theoretical points made by conducting a case study on an international telephone communications provider Brastel, which introduced significant innovations in international calling services, in the form of rechargeable pre-paid calling card, through effective application of standard IT. Brastel is situated against its main competitors, considering two dimensions of price and service breadth and convenience. A novel technique for measuring competitiveness based on price and service index is introduced. The following competitors were selected: NTT, KDDI, Japan Telecom, Fusion Communications, J-Call / World Link, G-Call, ASP Check, Primus, QuickPhone, and MCI. To create the service index, factors such as ease of use, convenience, number of languages in which the services are available, and additional features were taken into account. The company itself and the rechargeable card innovation were analyzed through in-depth interviews and data collection. It was shown that a competitive advantage was maintained through internal and external capabilities.

The purpose of this study is, to analyze the recent trend of studies on SaaS(Software as a Service) in Korea and to suggest a direction for the future research. For this purpose, the relevant literatures published in Korea Citation Index and literatures presented in conferences were gathered. Among these literatures, total of 39 samples were selected and used in the systematic literature review. The result shows that the application of SaaS in actual operations of industries are widely proliferated. However, the studies on SaaS generally lacks in its number and types. For example, studies so far are only on field of engineering and technology. Considering the fact that SaaS is moving towards the service orientation, studies on SaaS should develop in the fields of policy, business, individual and society sides of studies. In addition, the existing studies uses different concepts of relations between SaaS and ASP(Application Service Provider), as well as, different definitions of SaaS. Lastly, our research analyzed the problems of utilization of SaaS and found that, the quality, performance and security are presented as the core of the problems.

This study attempts to investigate the IT utilization and e-business level of the small and medium companies in order to facilitate their e-commerce efforts. Results show that they have basic IT infrastructures such as internet and PC, but they use their IT resources mainly for office automations. Major problems with such low level of IT utilization are in their lack of manpower, skill, and fund. Considering above issues, web hosting service is believed as a good measure to alleviate their problems. Hence, this paper suggests that utilization of the web-based ASP can be a viable solution for the currently revealed issues. Also, development of creative IT application(business) cases and their advertizement can lead small and medium finns to more productive IT investments, which requires more diverse IT performance measurements such as BSC(balanced scorecard), other than traditional ROI.

국내 50인 이상, 매출 100억이상 규모의 중소제조업을 위한 생산정보화는 그간 정부의 정보화 지원사업의 지원으로 중소제조업에서 평균 생산성 22%이상의 성과를 달성하였다. 그러나, 50인이하, 매출 100억 미만의 국내제조업은 약 20만개 이상이 되고 있으나, 정부에서 지원하고 있는 정보화지원사업의 혜택을 받지 못하고 있다. 그간 ERP, SCM 등과 같은 기업정보화의 경우 ASP (Application Service Provider)모델을 개발하여 적용을 시도하여 보았으나 활성화되지 못했고 생산자원 4M (Man, Machine Material & Method)정보를 실시간 처리가 요구되는 생산정보화의 경우에는 기술적 문제로 인하여 적용 시도조차 할 수 없었다. 최근 RFID/USN, 개방형 임베디드, 모바일, 차세대 인터넷 및 SOA (Service Oriented Architecture)기술의 급속한 발전으로 전세계 산재되어 있는 복수 공장의 생산자원을 중앙에서 서비스기반으로 중앙관리가 가능하게 되었다. 본 논문에서는 50인 이하, 매출 100억 미만의 군소제조업의 생산자원 4M을 유무선 센서 기술을 통하여 자율 재구성 능력 (Autonomous Reconfigurable) 기반의 원격관리가 가능한 핵심기능의 소개와 복수 공장의 다양한 생산정보화 애플리케이션을 단일 표준 플랫폼으로 구현할 수 있는 적용 모델에 대하여 설명한다.

From both techlical and economic viewpoints, DiffServ IP QoS architecture is accepted as a more practical solution because of the complexity Problem of the other IntServ architecture. In this paper, we propose several models to support DiffServ QoS in DSL broadband access networks and discuss about migration path from current best-effort DSL networks to DiffServ-enabled ones. Since DSL networks are recently and widely deployed in the world amount ot new investment, compatibility with existing QoS-unaware DSL systems, and compatibility with existing charging systems as well as effective support of various QoS services must be carefully considered when we design DiffServ QoS support models in DSL networks. The DiffServ models proposed in this paper are divided into static DiffServ models and dynamic DiffServ models which are near-term solutions and long-term solutions repecitively. The static DiffServ models include Flat DiffServ which suworts per-subscriber DiffServ QoS and Structured DiffServ which supports per-subscriber and per-service DiffServ QoS. And the dynamic DiffServ models include Direct DiffServ for P2P(Peer to Peer) applications and Indirect DiffServ for ASP(Application Service Provider) applications.

The basic concept of an improved business and productivity for Small and Medium Sized Enterprizes, which makes use of an information portal, is to assure competitive power, increase the production quantity through the interchange of a company and the outside environment, and to build cooperation. To reduce the charge of the equipment, as well as to introduce and information program, it should build an information environment from inside the company by suing the information portal ASP(Application Service Provider). This portal is already built by the basic information infrastructure through the Internet.

Computer Resource의 대용량화 및 인터넷 속도의 발달은 원거리에서 사용자가 인터넷을 통해 서버에 접속하여 컴퓨터를 사용하는 요구를 증가시켰다. 이는 Server-based 원격 컴퓨팅을 활용한 서비스의 연구 개발을 활성화 시켰으며, 최근 들어서는 Thin Client를 기반으로하는 중앙 집중형 원격 데스크탑 시스템(Remote Desktop System)을 꾸준히 발달시켰다. 그러나 단순한 파일 데이터의 접근에 대한 보안만을 제공하는 현재의 보안 체계는 이러한 Server-based 컴퓨팅 환경에서 다수의 사용자에 대한 복잡한 형태의 정보 공유 및 미세한 수준의 접근 권한이 요구되는 경우에는 적합하지 않다. 본 논문에서는 ASP(Application Service Provider) 컴퓨팅 시스템과 같은 중앙 집중형 원격 데스크탑 시스템에 적용하여 하나의 응용 프로그램에 대해 사용자별 세부적인 하위명령 사용 제한을 수행하는 사용자 명령 인증시스템을 제안한다.

A protocol for the web-based GPS data processing system has been developed. The system is developed following the typical ASP system, in which the GPS data acquired by various users can be uploaded through the web and the data is processed with data processing components selected by the users. After the processing, the results are also transported to the users through the web. The developed system is designed for easy software upgrade and it is an synchronous process mode so that the multiple accesses can be handled with high user flexibility. The database components for the efficient GPS data maintenance are developed so that the data from CORS can be used for the data processing. Currently, the absolute and relative positioning algorithms using code measurements are integrated and much more algorithms such as the data quality control, absolute and relative positioning using phases will be integrated in near future.

BIM has been increasingly deployed to the construction industry in order to minimize ambiguity and to reduce errors of the communicated engineering information, for which poor communication due to fragmented industrial structure is mainly responsible. Known BIM use cases and related researches are focusing either (1) on a specialized solution for a given specialty area (e.g. structural engineering planning and early design, material take-off, constructability simulation, etc.), or (2) on handling interoperabillty issues with Industrial Foundation Classes (IFC); Neither of these approaches have sufficiently catered for collaboration and information management in actual construction projects. This paper proposes the strategy for BIM+PMIS (project management information system) system focused on improving PMIS which has been commercially provided with ASP(Application Service Provider). It also describes the architecture of the BIM-based information management module prototype, which is a key component of the BIM+PMIS system.
