This study proposes a research framework for IT service management (ITSM) area based on theories on innovation and IT achievements in the area of MIS. Then, existing ITSM literature is reviewed based on the research framework, and implications for future ITSM research are suggested. Major findings are as follows: (1) domestic research efforts should be continued to contribute to the diffusion of ITSM in industry, (2) since a certain level of research results has been accumulated, explanatory research rather than exploratory and/or descriptive studies should be pursued in the future, (3) research on the performance of ITSM is lacking, (4) research utilizing more objective data (secondary data obtained from ITSM systems) is needed. ITSM is innovation that can contribute to the improvement of productivity and competitiveness of organizations through systematic management of IT. It is expected that the research framework and implications of this study can assist future research efforts and practical utilization of ITSM.

사회기반 시설물들의 노후화로 유지보수 비용이 급격하게 증가하고 있는 선진국뿐만 아니라 국내에서도 시설물을 체계적으로 관리하여 안전사고를 예방하고 유지관리 예산을 절감하고자 하는 관심이 날로 증대하고 있다. 해외의 뉴질랜드, 호주, 캐나다, 미국, 영국 등의 나라에서는 공공시설물 유지관리에 자산개념을 도입하여 관련 법과 제도를 정비하고 대웅적 유지관리방식보다 자산의 가치 중심의 예방적 유지관리로 전환하여 일정 부분 성과를 내고 있다. 국내에서도 시설물을 체계적으로 관리하여 안전사고를 예방하고 유지관리 예산을 절감하고자 하는 관심이 날로 증대하고 있다. 이에 IIMM의 자산관리 업무절차 모델과 국내에서 제시된 KTAM-40을 비교하여 공공시설물 자산관리 정보시스템의 설계방안을 제시하고자 한다.

공공부문 정보화사업의 효율적인 관리를 위해서는 정보화사업의 특성을 반영한 관리방법론이 필요한 상황이다. 그러나 기존의 유사한 프로젝트관리의 경우 그 내용이 시스템공급자 위 주로 되어 있을 뿐만 아니라 추상적이고 다양한 해석을 가질 수 있어 공공부문에서는 적용하기에는 어려움이 많았다. 따라서 본 연구에서는 공공부분에서 정보화사업이 갖는 특성을 반영하여 개별 사업에 따라 관리를 용이하게 하고, 성과측정 기반의 관리 모델을 제시하였다. 제시한 관리방법론 프레임웍은 실증분석과 보완을 거쳐 최종적으로 국내의 다양한 정보화 사업 프로그램과 각 부처의 독자적인 사업관리에 적용될 수 있을 것으로 판단된다. 이러한 사업관리방법론의 적용을 통해서 사업관리의 과학화 및 체계화를 이루어 궁극적으로 정보화사업의 성공적인 추진 및 관리를 도모를 기대한다.

This case study for a homeshopping company shows that the management of returned apparels by the partnership system increases the velocity of the returned goods, which not only minimizes the products' value loss but also improves the company's management performance. By incorporating the partnership system, following significant performance improvements have been identified: First, decrease in transaction cost and time between the homeshopping company and the partnering companies. Second, concentration of production line, accurate schedule management of receipt/delivery as well as collection of goods. Third, improvement of efficiency in procedures of returned goods and quality improvement of product provided by the partner.

The previous studies found the importance of market orientation (MO), learning orientation (LO), and marketing capabilities (MC) in driving firm performance (FP), but respectively. This research attempted to integrate the rather separate research streams of MO, LO, and MC in explaining FP. How MO and LO, as two critical constructs of organizations' cultural values, affect FP was examined with the mediating role of MC (composed of marketing planning capability (MPC) and marketing implementation capability (MIC)). Specifically, we derived specific conceptualizations on the effects of LO on FP through MO, MPC, and MIC as well as the effect of MO on FP through MPC. Accordingly, we empirically tested a process of how LO, MO, and MC translate into FP, using survey data of 146 respondents from Korean companies. The results successfully supported our model. It is worth noting not only that LO and MO are found to have synergistic effects on FP through MC but also that LO fosters MO. The relevant implications of our findings are presented with limitations and further research directions.

The PBNM on MANET is being researched to ensure the reliability and efficiency between mobile nodes. Therefore, it is essential to determine the cluster effectively which will perceive the movements of nodes and distribute the policies. In PBNM mechanism, to determine the node cluster for PDP and manage PEP nodes, Active PDP Discovery Protocol is proposed as a mechanism which is more efficient than preexistent techniques. While k-hop cluster selects the PEP nodes which PDP node manages, Active PDP Discovery actively selects the PDP node among the moving PEP node. This method prevents orphan nodes that are not connected to PDP and reduces continual broadcasting messages. This paper implements Active PDP Discovery which determines cluster in the real networks and analyzes its capability, expanding COPS-PR to detect the movement of nodes and adding MNL to PDP node.

IISO/IEC 9594-8 defines the public key framework and attribute certificate framework. Attribute certificate framework deals with privilege management infrastructure(PMI). In PMI, for privilege management using attribute certificates, role assignment certificates and role specification certificates are used to assign and specify privileges independently. Role specification certificates includes privilege specifications and the details far privilege management of network environments. Privilege management of unreliable network environment tries to enhance the reliability and efficiency of privilege information transmission forwarding over unreliable routes in the presence of potentially faulty nodes and edges. Each node forms a role specification tree based on role specification relationship data collected from the network. In this paper privilege management cost with the role specification certificates tree structure is evaluated trying to reduce the overhead incurred by role creation and modification of privileges. The multicasting of packets are used for scalability. We establish management cost model taking into account the packet loss and node reliability which continuously join and leave for network. We present quantitative results which demonstrate the effectiveness of the proposed privilege management scheme.

With the emergence of serverless computing paradigm and the innovations of cloud technology, the structure of backend server infrastructure has evolved from on-premises to container-based serverless computing. However, an access control on the server still heavily relies on the traditional SSH protocol, which poses limitations in terms of security and scalability. This hampers user convenience and productivity in managing server infrastructure. A web shell is an interface that allows easy access to servers and execution of commands from any device with a web browser. While hackers often use it to exploit vulnerabilities in servers, we pay attention to the high portability of web shell technology for server management. This study proposes a novel proxy-based server management framework utilizing web shell technology. Our evaluation demonstrates that the proposed framework addresses the drawbacks of SSH without additional overhead, and efficiently operates large-scale infrastructures in diverse computing environments.

This study aims to investigate the current status of the operation system of the curriculum support extra-curricular program, focusing on the extra-curricular program operation system of other universities, and suggest the desirable operation system and performance management plan of the extra-curricular program in cultural education. To this end, the analysis of the extra-curricular program operation system of eight four-year universities in the Seoul metropolitan area was conducted on the existence of core competencies, computer systems and extra curricula program guides, credit-linked and mileage scholarship programs, and the analysis focused on the characteristics, merits and demerits of each university's operating system. It was also intended to propose the desirable operation system and performance management plan of the extra curricula program in liberal arts education, focusing on the operation system of the extra curricula program of E University and the corresponding performance management. Conclusion To operate the extra curricula program efficiently, the computer system and the extra curricula program guide, credit link and mileage scholarship system should be introduced. In addition, the analysis of the operation system of the curriculum support program of E University shows that E University operates systematically with the direction of operation of the core competency-based curriculum support extra-curricular program, and the performance management of the extra curricula program of E University is carried out through the EU-TQM System Integrated Management System.
