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.

VOD service provides an additional revenue for broadcasting companies in addition to the existing subscription fees and advertisement-based revenue. Therefore, each broadcasting company develops its own VOD service and performs frequent improvement work. This leads to the development of new VOD services, so developers are considering ways to effectively handle the frequent development needs. In this background, we conducted an underlying research to apply the feature-oriented analysis model to the development of VOD service. The feature-oriented analysis model used in this study is the Feature-Oriented Domain Analysis (FODA) developed by SEI of Carnegie Mellon University. FODA provides a tool for specifying a feature model of a software domain, based on which developers determine the configuration of a software with customers. This study developed a feature model of the VOD service domain and devised the functionalities and testcases in an integrated manner with the feature model. Additionally, we proposed a VOD service development process utilizing the feature model, function specification, and testcases.

컴포넌트 기반 개발 프로세스는 그 동안의 구조적 분석/설계 기법과 정보공학, 객체지향 등의 공학적 분석기술을 수용하고 있다. 따라서 CBD를 적용하려는 조직은 다양한 소프트웨어 공학적 기법과 아키텍처 설계 기술들을 습득해야 하였다. 또한 CBD의 핵심 역량인 반복적 개발 프로세스와 아키텍처 설계 역량을 갖추기 위해 각 개발업체 들은 CBD기술의 도입초기에 상당한 혼돈과 어려움을 겪어야 했다. 이에 본 논문에서는 CBD를 조직차원에서 습득하고 적용하는 과정을 5개의 단계로 나누고 각 단계의 목표를 설정한 컴포넌트 개발 프로세스 성숙도 모형을 제시한다. CDMM(Component based Development capability Maturity Model)으로 명명한 본 개발 능력 성숙도 모형은 소프트웨어 개발조직이 CBD를 습득하기 위해 어떤 단계를 거쳐야 하는지 또한 컴포넌트 개발을 위한 핵심기술이 어떤 것들인지를 제시한다. 이는 향후 CBD를 확산시키고 컴포넌트 기술을 통한 생산성향상과 소프트웨어 개발비 절감을 위해 기업과 국가의 정책적 지표로 활용할 수 있을 것이다.

광범위하게 이용하고 있는 웹은 기존에 텍스트나 이미지만을 제공하던 정적인 정보에서 사용자 위주의 서비스 중심으로 변화하고 있다. 웹 환경의 변화는 Web Services를 등장 시켰고 산업계에서 이미 이를 위한 표준화 작업 및 표준에 따른 Web Services 개발을 주력하고 있다. 이에 Web Services를 이용한 어플리케이션 개발이 또 다른 소프트웨어 공학적 이슈로 대두되어 그를 위안 연구가 진행 중이다. 본 논문에서는 Web Services 어플리케이션 개발을 위한 목표 지향 분석 방안을 제시하고 결론과 시멘틱 웹 의 표현 기준의 하나인 DAML로 변환하는 알고리즘이 향후 연구되어야 할 과제임을 논한다

Cloud Computing is emerged as an effective reuse paradigm, where service providers operate hardware and software and as a service, and service consumers invoke the service through Internet. Software-as-a-Service (SaaS) is a type of cloud services, where the whole software is designed as a service so that several consumers can reuse the SaaS. While tradition software applications are developed for a specific organization, SaaS is developed for multiple users in the various organizations. Hence, reusability is very essential characteristic of SaaS. Reusability is defined as a metric of how effective and efficient software functionalities can be used by various users. Reusability in SaaS is evaluated by considering three sub-characteristics; applicability, adaptability, and scalability. Since such a SaaS has considerable differences and characteristics from traditional software applications, conventional methods including object-oriented modeling, component-based development method, and service-oriented architecture (SOA) service development method would be limited in developing services which can fulfill these three sub-characteristics related to reusability as well as SaaS-intrinsic characteristics. Hence, there is a great demand for effective processes for developing SaaS cloud services. In this paper, we present a practical process for developing SaaS, which focuses on ensuring reusability. And by performing a case study with our proposed SaaS development process, we evaluate applicability of our proposed process and explain how the process is used in a real domain. Then, we compare our proposed process with others for verifying our study. Through the proposed process, cloud services with high quality can be more effectively developed.

VOD (Video-On Demand) Services are considered to be one of the most successful data broadcasting services, along with Electronic Program Guides (EPGs). In particular, VOD services provide supplementary revenue for broadcasting companies in addition to the existing subscription fees and advertisement-based revenue. Therefore, each broadcasting company has developed its own VOD service and constantly seeks to improve it. This leads to the development of new VOD services, so developers are considering ways to effectively handle the frequent development needs. In this background, we conducted underlying research to apply the feature-oriented analysis model to the development of VOD services. The feature-oriented analysis model used in this study is the Feature-Oriented Domain Analysis (FODA) one developed by SEI of Carnegie Mellon University.

Most of electronic medical record systems which have been built in Korean hospitals are based on source oriented medical record approach. These systems hardly satisfy diverse objectives owing to the innate imperfections in system architecture and development methodology. Thus, the hybrid of source oriented and problem oriented approach is highly desirable. The purpose of this study is to present an architecture and methodology required to construct hybrid electronic medical record system and to develop a prototype based on them. Analyzing the clinical processes and data requirements of problem oriented medical record approach we developed a software process model as weel as an architecture model which consists of legacy system, clinical data repository, problem list database, prospective plan database, user interface, and synchronization procedures.

시스템통합(SI)이란 소프트웨어, 하드웨어, 네트워크등 사용자요구에 적합한 솔루션을 적시에 제공하는 종합적인 정보서비스 체계를 의미한다. SI사업은 90년대 들면서 연평균 30-40% 급성장을 통하여 소프트웨어산업을 넘어 정보통신산업의 핵심으로 급부상하고 있다. 이에따라 한국통신은 고객중심의 미래경영체제로서의 전환을 통하여 WTO 체제하의 국제경쟁 환경을 극복하고 고객의 다양한 요구를 신속하고 편리하게 일괄처리해 줄 수 있는 국내 최대의 SI프로젝트인 통합고객정보시스템(ICIS: Integrated Customer Information System)개발에 착수 하였다.

Recently, development paradigm of information system is turning into object oriented and component based, and this methodology is leading the software industry. To acclimatize aptly to this trend, users demand the assessment of software expenses to change with the appropriate model of computing costs of the environment, and some people are actually studying the concept of Object Oriented Function Point and UCP method. Especially, Object Oriented Function Point Measurement Process has good points in overcoming the bound of LOC and the existing the Function Point Measurement Process because Object Oriented Function Point Measurement Process is applicable to the early stage of development project mainly with the used cases, and valid to the life long period as the each stage of software products develops, and always understandable to communicate with users by the UML mark rules. Accordingly, this research is to measure Functional Point at ROFP and AOFP in accordance with the development project of information system by the national defense CBD methodology procedures and UML Interrelation Analysis that are recently and widely used in the developmental environment of object oriented information system. Furthermore, this study suggests the measurement method to obtain Functional Point, and identifies service function and object/class function in the correlation analysis of use case and class based on the products and UML modeling via traditional FPA model and object oriented FPA model. Above all, this study is to demonstrate the improvement of traditional Function Point Measurement Process, IFPUG-CPM and software cost basis, and reveal Function Point Measurement Process, which is appropriate to the development of object oriented information system, and suggest the evaluation results of the compatibility through case studies.
