Today's ERP system has become a core system of IT·SW that not only supports and manages enterprise resources efficiently, but also encompasses major business tasks. In other words, the ERP system is an essential strategic element for the survival of a company as a powerful means to innovate the management of an organization. This study analyzed the impact on the utilization of IT·SW from the perspective of the entire organization's process without limiting the performance evaluation of the ERP system itself, which is a core system of a company. The measurement data for evaluating the performance of the ERP system was the 2018 domestic company IT·SW utilization survey result report (subject to survey : 3,017 domestic companies with 10 or more employees). Based on this data, this study analyzed the impact of the ERP system on the entire enterprise's IT·SW utilization. In particular, attention was paid to whether there would be a difference in the use of IT·SW if the type of ERP system introduction was changed through the improvement of the business process of the company. Multiple regression analysis was performed using the statistical package SPSS 25. As a result, among the ERP system introduction types, the greatest degree of (+)influence on the company's IT·SW utilization is when the ERP package SW or ASP service is used as it is. Although the difference is insignificant, the second case was to build an ERP system through self-development or outsourcing, followed by customizing the package SW or system through self-development or outsourcing. Through the results of this study, it is expected that the organization will improve the business process and use the standard ERP package SW as it is without modification, thereby effectively enhancing the use of IT·SW of the company and leading to management performance.

The major objectives of this study are to identify the key organizational factors that facilitate and/or inhibit the IS outsourcing in Korean hospitals, and to analyze the differences between adopter & non-adopters and successful ones and not-successful ones. In order to achieve the research objectives, we derived comprehensive lists of potential facilitators and inhibitors from the past research, and conducted a field survey on 135 hospitals in metropolitan area. The analysis results suggest that organizational, financial and strategic factors are the most important facilitators, while organizational, psychological, vendor-related and environmental factors are the most important inhibitors. In addition, it was found that factors differentiating adopters and non-adopters are organizational factor(facilitator) and environmental factor(inhibitor) while strategic factor is a differentiating one between successful hospitals and unsuccessful ones.

Due to the recent advancement of cloud computing, the research on database outsourcing has been actively done. Moreover, the number of users who utilize Location-based Services(LBS) has been increasing with the development in w ireless communication technology and mobile devices. Therefore, LBS providers attempt to outsource their spatial database to service provider, in order to reduce costs for data storage and management. However, because unauthorized access to sensitive data is possible in spatial database outsourcing, it is necessary to study on the preservation of a user's privacy. Thus, we, in this paper, propose a spatial data encryption scheme to produce outsourced database from an original database. We also propose a k-Nearest Neighbor(k-NN) query processing algorithm that efficiently performs k-NN by using the outsourced database. Finally, we show from performance analysis that our algorithm outperforms the existing one.

The POSCO Outsourcing Partners(POSOP) consisted of 59 companies plays an important role in creating jobs in Gwangyang City of Jeonnam Province, the representative steel city of Korea. However POSOP are suffering from a job shortage. The purpose of this study is to analyze the mismatch between job-seekers and job-openers in relation to employment in Gwangyang City. As a result of the job-mismatch analysis of nine factors, there was a clear mismatch in recognition of suppliers, access to corporate and employment information, employment information acquisition path, and employment preference factors. However, there was no mismatch in the factors of employment avoidance and difficulty in the job-seeking and recruitment process. As solutions to the mismatch, it proposes to redefine the role of POPOS, promote capacity building projects for labor-management co-prosperity and cooperation, and gradually promote related projects in connection with the master plan related a comprehensive plan for youth jobs.

Following principal-agent relationship between government and funding agency effects on efficiency and management of project, this paper suppose that project management cost rate variable on outsourcing and administration of institution, applies multiple regression analysis and logit analysis by using factors that procurement status of institutional operating expenses and each subordinates scale (Budget, subject number) and method (Top-down/Bottom-up), not a total amount, for examining factors following project efficiency analysis and way of commission. The major variables which effect on efficiency of institution are management cost scale (0.36), institutional operating expenses ratio (-0.47), way of outsourcing, the factors that affect way of outsourcing are portion of project management cost (-38.5) and institutional operating expenses rate (-11.7). This means both legal and financial stability are necessary and it is avoidable moral hazard and adverse selection on principal-agent problem.

최근의 기업 환경은 고객욕구의 빠른 변화, 글로벌 경쟁의 격화와 급격한 정보기술의 발전으로 변화의 속도가 가속화하면서, 경영의 위기와 기회를 동시에 맞고 있다. 이러한 환경 속에서 기업의 핵심역량 강화와 경쟁우위를 위하여 필요한 정보기술을 어떻게 빨리 확보해서 활용하느냐가 매우 중요한 관건이 다. 종전에 는 이를 기업 내부에서 수행했으나, 요즈음은 외부 전문 업체에게 아웃소싱을 하는 추세이다. 이에 따라 국내 기업의 정보시스템 아웃소싱의 사례 연구를 통하여 아웃소싱의 위험 요소와 문제에 대한 방안을 제시하고자 한다.

The purpose of this study is to improve the calculation method of the software operation pricing proposed by the software business price calculation guide from 'input manpower method' to 'rate calculation method'. The software operation pricing of the input manpower method is not objectively calculated in the domestic IT outsourcing situation where the statistical data based on the activity based estimating is insufficient and it is decided by agreement between the owner and the client. In addition, there was no standard for adjusting the productivity according to the characteristics of the operation service. In order to improve this, an operational correction factor item that can affect the software operation productivity was selected based on foreign and domestic standards, and it was confirmed through the first questionnaire to IT operation managers. In order to determine the level of difficulty of the fixed operational correction factors, the operational correction factor using AHP technique was confirmed through a second questionnaire for pairwise comparison. The operational difficulty calculation table was developed with reference to COCOMO and ITIL standards. Finally, we propose a new pricing scheme that reflects the operating rate. Regression analysis was carried out by collecting the data of the domestic public institutions on the estimated cost and the actual cost calculated from the new rate method software operation pricing. The results of the regression analysis show that the estimated cost and the actual cost are related to each other. Mean magnitude of relative error(MMRE) and PRED[25] analysis were added for accuracy analysis. MMRE and PRED also showed satisfactory results, confirming the possibility of replacing the rate method software operation pricing.

The interest in SLA in accordance with the development of IT outsourcing has increased due to the rapid development of information systems. Moreover, an awareness and necessity for the Information System Operating Audit has increased while an effective IT service management operations for information systems is needed desperately. However, information system operations and maintenance instructions of the National Information Society Agency operates due to the current information system operation, but the experience and the interpretation of the auditor determine the decision in the field. This paper introduces an operating audit model for the efficient management. This model is derived from the Korea Information Society Agency's operating instructions of the Information Systems Audit and their inspection services. The audit checklists were derived from the areas of service planning, service delivery, service support, and service management. Consequently, the operating audit model was proposed, and the suitability of this model was verified by experts' opinions on the survey.
