Today many corporations converge clients' needs and IT technology, and then they are developing new service model in order to survive global situation. The changes of manufacturing industry from simple manufacture to industry for focus on services is getting speeded up, because not only growth of service part but also enlargement in creating value in services is expected. And services through collaboration with knowledge based service and only manufacturing industry is important. In this situation, this thesis is willing to propose methodology for Inter-Industry Collaboration Service Model. The proposed methodology includes procedures which develops service model, plans for Inter-Industry Collaboration Service Model and evaluating framework. Also, this applied case studies. I look forward to offering useful guideline on the proposed methodology in this study to corporations that try to create new service model through Inter-Industry Collaboration Service Model.

정보화의 물결은 도서관 정보센터의 서비스 형태에도 많은 변화를 가져왔다. 그러나 이용자의 입장에서는 어떤 형태의 서비스가 제공되더라도 기본적으로 이용자가 제공받는 서비스일뿐, 도서관 정보센터의 이용에 대한 정보 서비스의 만족도는 제공받은 서비스의 품질에 의해서 좌우될 수밖에 없다는 특성을 갖는다. 본 연구는 서비스 마케팅 분야에서 이용하는 서비스 품질 평가모형인 서브퀄(SERVQUAL) 모형을 도서관 정보센터에서 활용할 수 있는 모형으로 확장하기 위한 프로젝트인 라이브퀄 플러스(LibQUAL+) 모형에 대해 고찰하였다.

The purpose of constructing university information system is for improvement in diversification and throughput of information, streamlines business processes, rapid exchange of information, sharing of information, decision-making information, and securing educational facilities. Similar to business information technology system, university information system does not have a review system for sharing and overlapping investment of information. Due to the lack of project management for outsourcing and vulnerability of system suitability, system audit is absolutely needed for the university information system. This paper especially focuses on an operational phase in the audit of university information system. Additionally, we proposed operating model and checklists of the university information system based on Management Guidelines of ITIL V3 Operational and Information System. We derived the checklists of operation audit by each domain of service strategy, service design, service transition, service operation, and continual service improvement. As the result, this study appear to have more than average satisfaction the suitability results were.

지식사회에서 주요자원은 지식이 되며 이러한 지식을 관리하는 도서관의 역할이 매우 중요하다. 기하급수적으로 증가하는 지식정보들 중 조직구성원들이 필요하고 유용한 지식만을 선택하여 이용자의 취향에 맞는 형태로 제공할 수 있는 지식정보관리가 필요하다. 따라서 이 연구에서는 기존의 도서관 정보봉사에서 나타나는 문제점들을 해결하기 위해 도서관이 수행해야 할 역할 및 기능들을 Help-Desk 서비스 측면에서 온라인과 오프라인으로 구성요인들을 조사하고 분석하였다. 이 결과를 토대로 웹기반 Help-Desk 지식관리 시스템 모형을 제시하였다.

본 논문에서는 기존의 관련 연구를 SW 중심의 대가 산정, 비용-편익분석, 보안성 지속서비스 대가 산정으로 구분하여 조사하였고, 사례 분석은 미국과 일본, 국내 A기관을 대상으로 하였다. 이를 바탕으로 현 제도와의 비교를 통해 개선모델을 마련하였다. 비용-효용분석 측면에서 효용성이 높은 서비스 수준 협약(SLA ; Service Level Agreement)과 NIST Cybersecurity Framework를 적용하여 정보보호서비스별 특성과 수행기준, 가중치를 기준으로 대가를 산정하는 방식인 SCS(Security Continuity Service) 성과평가체계 기반 정보보호서비스 대가 산정 모델을 제안한다. 이 모델은 공공기관에서 정보보호서비스 대가를 객관적으로 산정하는 도구로 활용할 수 있다. 또한, 현재 권고수준인 법률을 적용 강제성 수준으로 강화, 국가기관 및 공공기관의 평가제도 개선, 국가인증기관의 정보보호서비스 검증제도 도입, 모든 정보시스템 및 서비스로의 확대 등을 통해 본 제도의 정착될 수 있을 것으로 기대된다.

The existing wired emergency call such as 119, 112 have its own location information to serving immediate rescue service. For the case of wireless emergency call by mobile phone, the location information should be provided by wireless network. This paper describes the network architecture and protocol for mobile emergency service referring TIAlEWJ-SID-036-A with reviews about technical issues, legacy factors and related researches. The mobile emergency service is divided into mobile emergency rescue service and mobile emergency alert service. The network reference model for mobile emergency rescue service is released in KOREA. In this paper, the interfaces between elements of the network reference model, and service scenarios, message flows are defined. Supplement to mobile emergency rescue service, the network reference model, interfaces and message flows for mobile emergency alert service are developed. The protocol is described by DID, and the proposed works are on processing for domestic standard of TTA.

Media service model is divided into 3 models that are Client Pull, Server Push, and IPP(Interleaving Pull & Push) model. In most single VOD(Video On Demand) environment, Client Pull model was sufficient to play the movie Because most media contents has a low bitrate and resolution. But according to an increment of the demand of the high definition media, Client Pull model is not sufficient. Parallel VOD environment is made of several of VOD servers and provides the parallel media stream simultaneously for one client. We compared and analyzed the performance of service models with respect to network delay and data size in buffer in the single and parallel VOD environment and we found that IPP service model keeps the least network delay and stable client buffer state in the parallel VOD environment.

We present in this paper the methodology for automatic generation of OWL-S service model ontology along with the results and issues. First, we extract information related to atomic services and their properties such as IOPE from the UML class diagram, and retrieve information related to the composition of services from the UML state-chart diagram. Then, the XSLT applications utilize the acquired information to generate the OWL-S service model ontology through the predefined mappings between OWL-S constructs for composite services and UML state-chart primitives. For the justification of generated service ontology, several validation checks are performed. Our service ontology generation method is general and fully automatic, as well as effective, in that it is achieved in an environment familiar to developers, and information needed to generate service ontology is provided necessarily during service development. It is also noticeable to facilitate representing the condition with GUI rather than a complex language such as OCL.

Purpose As the mobile easy payment service grows fast, competition in the payment service market is getting stronger. On the other hand, there are few studies on the users' utilization results. Therefore, this study explains the continuous use intention of mobile easy payment Services based on PAM and value model. Design/methodology/approach This study proposed an extended model by integrating PAM, which is a representative model of continuous use intention in IS field, and value model of mobile field. Also this study empirically tested 298 users who have experience of mobile easy Payment service. The structural equation model was used to verify the research model and hypotheses. Findings According to the empirical analysis result, this study verifies that perceived usefulness and satisfaction were determinants of continuous use intention in mobile easy Payment services. Expectation confirmation has been proved to be a positive predictor of satisfaction and perceived usefulness. Also, among the value factors, perceived ease was not a valid predictor of satisfaction, and the remaining factors were positive predictors of satisfaction.

Network-Centric Operational Environment(NCOE) service becomes critical in today's military environment network because reusability of service and interaction are being increasingly important as well in business process. However, the refinement of service by semantic similarity and functional similarity at the business process was not detailed yet. In order to enhance accuracy of refining of business service, in this study, the authors introduce a method for refining service by semantic similarity and functional similarity in BPMN model. The business process are designed in a BPMN model. In this model, candidated services are refined through binding related activities by the analysis result of semantic similarity based on word-net and functional similarity based on properties specification between activities. Then, the services are identified through refining the candidated service. The proposed method is expected to enhance the service identification with accuracy and modularity. It also can accelerate more standardized service refinement developments by the proposed method.
