Purpose: Of late, the focus of service design is moving toward emphasizing customer satisfaction and taking users' experience more seriously. In addition to the change in perspective in service design, scholars in this area are paying more attention to service design methodology and process, as well as its theory and real-world case studies. In the case of medical space, there have been few studies in attempting to apply service design methods useful for deriving user-focused results. The author of this paper believes, however, case study-oriented approaches are more needed in this area rather than ones focusing on theoretical aspects. The author hopes thereby to expand the horizon to practical application of spatial design beyond service design methodology. Methods: In order to incorporate the strengths of service design methodology that can reflect a variety of user opinions, this study will introduce diverse tools in the framework of double diamond process. In addition, it will present field cases that successfully brought about best results in medical space design. It will end with summarizing the ideal process of medical space design which is reasonable and comprehensive. Results: Medical service encompasses preventive medicine as well as treatment of existing medical conditions. A study in establishing the platform of medical service design consists of a wide range of trend research, followed by the summary of two-matrix design classification based on results of the trend research. The draft of design process is divided into five stages composed of basic tools for establishing spatial flow lines created by matching service design tools with each stage of space design processes. In all this, most important elements to consider are communication and empathy. When service design is actually applied to space design, one can see that output has reflected the users' needs very well. The service design process for user-oriented medical space can thus be established by interactions on the final outcome and feedback on the results. Implications: One can see that the service design with the hospital at its center produces the result that encompasses the user's needs best. If the user-focused service design process for medical space can be extended to other space designs, the author believes that it would enhance the level of satisfaction for users and minimize trials and errors.

Grid 컴퓨팅은 과학 분야에서 처음 시작되어 현재 과학 분야뿐만 아니라 e-business와 같은 더 많은 분야에서 폭 넓은 활용을 위하여 SOA(Services Oriented Architecture)를 채택하게 되었으며, SOA 프레임워크에 있는 기존의 어플리케이션과 프로그래밍 라이브러리를 통합하게 되었다. 특히 SOA에 기반을 둔 Clarens Grid 서비스 프레임워크는 권한 부여(authorization), 접근 제어(access control), Discovery Service를 제공한다. 본 논문에서는 Java로 구현한 JClarens를 이용하여 Discovery Service를 구현하는 두 가지 방법을 기술하고, 그 구현 방법으로 인해 발생할 수 있는 서비스 재등록으로 인한 네트워크 트래픽 증가에 대한 문제점을 진단하고 재등록을 위한 시간 간격을 차등화 함으로서 이 문제점을 해결할 수 있는 방안을 제안하였다. 따라서 Discovery Service는 Grid 컴퓨팅 환경에서 사용자에게 가장 적절한 자원을 발견할 수 있도록 지원 할 것이다.

Recently, software distribution method, along with advent of era of Web 2.0, is rapidly evolving from ASP(Application Service Provider) method into SaaS(Soft as a Service) method due to development in concepts and technologies including SOA(Service Oriented Architecture) Web Service, On Demand and Component. Determining factor in market competitiveness of newly emerging SaaS business model will be analyzed by focusing on Group-Wares, POS(Point of Sale) System, CRM(Customer Relationship Management) and ERP(Enterprise Resource Planning), which are the most representative SaaS business models in Korea. It is anticipated that the outcome of analysis of determining factors for market competitiveness for each of the main SaaS Business Models acquired through questionnaire survey can be utilized as important benchmarking material in setting the direction of cultivating SaaS market by the government as well as new entries into SaaS market.

International Civil Aviation Organization adopted the program to improve performance of aviation-related data systems through the ASBU for 20 years from 2013. Research and development for integrated management network of aeronautical telecommunication data through SWIM(System Wide Information Management) technology which is part of program, are being progressed in the United States and European countries. Therefore, in this paper, we suggest a method of testbed implementation based on technology of aeronautical data services architecture applied the concept of SOA(Service Oriented Architecture), development of future data management model for integrated management of aeronautical data, and development of user-centric integrated aeronautical data management network through adapter technology for interoperating legacy aeronautical data system to develop even technology with development trends of advanced countries.

그리드 어플리케이션을 분산, 병렬 환경에서 효과적으로 만들기 위해, 그리드 포탈시스템인 Workflow based grid portal for problem Solving Environment(WISE)를 개발해왔다. WISE는 Globus Toolkit 2를 기반으로 그리드 워크플로우 기술을 사용하여 사용자가 좀 더 쉽게 그리드 어플리케이션을 프로그래밍 할 수 있는 환경을 제공한다. 그러나 현재 그리드 기술은 서비스 기반 구조(Open Grid Service Architecture)로 변화하고 있고 WISE도 기술적 흐름에 따라 그것을 충족시킬 수 있도록 변화해야 한다. 그래서 서비스 기반 구조에 대응할 수 있는 워크플로우 엔진을 새로 설계하여 WISE에 적용하고자 한다. 새로 설계한 시스템은 Service Oriented Workflow System on Grid(SOWS-G)이다. 이것은 계산량이 많은 문제에 대해 효과적으로 분산, 병렬 실행을 가능하게 하고, 다양한 워크플로우 패턴을 지원하며, 웹 서비스를 이용할 수 있도록 설계하였다. 이 논문에서는 SOWS-G를 서비스 기반 그리드 환경을 지원하는 Globus Toolkit 3를 이용하여 설계한 구조를 살펴보고 웹서비스를 이용할 수 있도록 추가된 기능들에 대해서 설명하고자한다.

Service science is a new application area that implements services in an interdisciplinary area of management, economics, and engineering. Service systems provide functionalities of traditional software systems, moreover the functionalities are more intellectual in that they require dynamic context awareness, analysis, and decision making based on the recognized and analyzed contexts. However, conventional software development approaches do not sufficiently provide methods to model the service requirements and to design service-intensive systems. Therefore, there is a great demand on effective methodologies for developing service systems. In this paper, we compare traditional software systems with service-intensive systems in order to identify characteristics of the service systems. And, we propose a step-wise process to model service systems, in terms of architecture, components, and workflows. Then, we show a case study on an emergency handling system which is a type of living assistant systems. We believe that the proposed approach can be used in developing high-quality service systems effectively.

SOA has become the focus of attention as it is perceived as a concept toward integrative service which helps companies respond quickly to the changes in market needs. This study is aimed to find out success factors for building SOA. We carried out two case studies on companies that adopted SOA successfully in Korea and conducted a survey to collect opinions from experts and experienced managers whose job is related to SOA. The critical successful factors found in this study include: 1) establishment of the SOA taskforce based on CIO's strong support, 2) formation of the corporate-wide consensus and the adoption of standards, 3) active user participation in defining services and obliterating duplication, 4) accomplishment of flexibility in services and business agility based on integrated infrastructure, and 5) securing project budget and consistent support by way of using measurement index for SOA investment effects.

서비스 지향 구조 (Service-Oriented Architecture)는 독립적으로 구성된 렙 서비스(Web Services)들을 프로세스 중심적으로 연결시키기에 적합한 소프트웨어 시스템 구성 방식이다. 하지만 SOA의 규모가 커질수록 제공되는 서비스들의 숫자 또한 증가하게 될 것이며 그런 상황에서 사용자가 원하는 서비스를 직접 찾아 이용하는 것은 불가능하다. UDDI는 사용자에게 기술적인 정보만을 제공하기 때문에 이러한 문제를 적절하게 해결할 수 없다. 그에 비해 서비스 통합(Service Integration)은 서비스들이상호 동작하여 사용자에게 통합된 서비스를 제공할 수 있기 때문에 UDDI의 한계를 극복할 수 있다. 하지만 서비스 통합의 장점과 영향들은 아직 분명하게 규명하지 못하였다. 이 논문에서는 서비스 통합의 한 형태인 서비스 중개자(Service Broker)클 구현하고 평가하였다. 구현된 중개자의 비지니스 모델은 콜 택시 서비스이며, 콜택시 서비스 중개자는 접근성, 확장성, 재사용성, 유연성, 안정성 등에서 향상된 기능들을 제공하였다.

Knowledge-based Service Industry is an industry that creates added value through the production, processing, and use of knowledge. Comparing to other service industries, it is innovation-oriented business endeavors having the characteristics that exert the great influences on other fields. Meanwhile, however, research efforts thereof are yet insignificant. In this study, we analyzed the innovation performance of architectural design office which creates knowledge services, having raised the necessity of innovation of the design office. The innovation performance were classified according to the extent of efficiency of the architectural design office making use of DEA-Tier analysis, and, for those architectural design offices that showed significant differences in efficiency, we presented the case studies of the firms that were substantial benchmarking targets from short, medium, and long-term perspectives.
