The purpose of this study was to investigate the status of the operation of small libraries in Seoul and to assess the perception of their importance and satisfaction. For this purpose, 861 small libraries in Seoul were surveyed on the overall operational satisfaction, operational improvement, and the importance of operation. As a result, it was discovered that there is a demand for increased operational support for small libraries, enhanced publicity, improved education and treatment of volunteers, improved quality of the book collection, and continuously improved space and facilities. Furthermore, the public and private libraries should be classified to reflect operational characteristics of the operating entity, rather than implementing the uniform budget support and guidance management.

The most important task in acquiring the weapon system is to determine the required performance and to test & evaluate it. The importance of the weapon system by ROC (Required Operational Capability) is not considered, and system development and test evaluation are carried out. In addition, technical incidental performance is tested on the same basis as ROC in the test evaluation and determined according to the result. Development test and evaluation that evaluates technical ability is very important, but development agency is supervised and performed. In this paper, we propose a method to give weights considering the importance of ROC, a technical incidental performance determination and test procedure, and a improvement plan for the development and operational test & evaluation.

Recently, IT outsourcing has been one of the major concerns of many companies. This study proposes a model which composed the outsourcing planning and operational risks affecting the outsourcing performance. Especially, this study focused on the contractors perspective, because the outsourcing risk relative researches are recently performed on the service receivers perspective, contractors perspective researches were relatively lacked. The result of this study, outsourcing planning risks had not affected the outsourcing performance but it had positively affected the operational risks. And also, the outsourcing operational risks had negatively affected the outsourcing performance. For this reason, It is necessary to reduced planning risk induction for the outsourcing performance improvement. Because the planning risks positively affect the operational risks, it is necessary to reduced planning risk induction for the outsourcing performance improvement.

The market of the municipal wasetewater treatment plant (MWTP) operation is expanding across the world including Korea. The contracting-out system was introduced for the effective operation of MWTPs. However, an improvement of the contracting-out system of MWTP has been continuously required. This research investigated current operational status of MWTPs in Korea, to suggest the improvement of the cost effective MWTP operation to promote the contracting-out system of MWTP operation. Results showed that lower operational costs of MWTP were lower in larger MWTPs than in smaller MWTPs. Overall, MWTPs operated by a public enterprise showed lower operational costs than those operated by government agencies and private enterprises. Among the MWTPs similar in their treatment capacity, treatment process and operation period, MWTPs operated by private enterprises showed the lowest operational cost. According to the survey, managers and operators of MWTPs emphasized the importance of improvement on the methods of selecting operating agencies and estimating operationing costs. The results of this study should be useful as important supporting data to promote the contracting-out system for the MWTP operation.
