야간의 잉여전력으로 열을 저장해두었다 주간에 이용하는 축열공조에는 50여년에 걸친 긴 역사가 있었다. 이 방식이 가지는 효용에 일찍부터 눈뜬 선각자들의 노력에도 불구하고 당초 보급은 늦어져 그다지 진전이 없었다고 한다. 이러한 정세가 일변한 것은 전력공급에 병목현상이 생겨 부하 평준화가 안정공급에 있어 필요불가결의 과제가 되었기 때문이다. 특히 공조는 피크성이 강한 수요이므로 공조용 전력을 야간으로 옮기는 작업의 이점이 큰 것은 당연하다. 비 수요시간대의 요금이 큰 폭으로 떨어짐으로써 수요자측에서 보아도 야간의 전력을 어떻게 활용할까하는 것은 매력적인 연구테마였다. 이리하여 축열공조가 관심을 불러 보급이 기도에 놓인 지 2O년 가까이 되었다. 처음에는 물을 사용한 축열이 대부분이었으나, 축열조 용량의 제약으로 얼음을 만들어 저장하는 빙축열방식이 도입되어 현재의 표준적인 축열방식이되었다. 그러나 빙축열에도 비용상의 문제가 있어 전면적인 보급에 이르기까지는 아직 연구의 여지가 더 남아있는 듯하다. 한편, 교토의정서의 발효 등에 의해 지구환경에 대한 관심이 높아지게 되었다. 이 같은 배경 속에 건물및 건축설비의 에너지절약 기술의 중요성이 대두되고, 특히 창 주변의 공조방식, 조광제어, 축열 공조시스템 등, 건물부하의 직접적인 저감과 전력부하 평준화에 의한 환경부하저감 및 운영비용의 저감을 목적으로 한 건물일체형 설비시스템을 적극적으로 도입하기에 이르렀다. 환경을 배려한 건축구조.설비시스템의 채택 사례가 증가하며 건축물 종합환경성능 평가시스템과 성능검증 등 건물설비의 평가.검증 수법도 연구되어 건물에 적합한 운용면에서의 사고가 중요함이 인식되었다. 이와 같이 건축구조와 설비시스템의 양면에서 에너지절약성 및 환경성, 쾌적성, 편리성의 추구가 적극적으로 도입되는 가운데, 슬래브축열시스템은 건축구조와 공조설비가 균형있게 융합됨으로써 초기비용의 삭감과 부하 평준화에 의한 경제성 향상, 복사에의한 실내환경의 향상 등의 효과를 기대할 수있는 시스템으로 추목받고 있다.

The goal of this paper is to examine the effects of a CDSS(Clinical Decision Support System) for drug prescription on organizational performance in medical institutions using POC(Point Of Care) systems. For achieving this goal, evaluation factors for influencing performance of information system were identified by using the performance evaluation model for CDSS. In the results, there was significant causality between each evaluation domain except system quality domain. In addition, the system quality of CDSS for optimal drug prescription has no influence on user satisfaction. But information quality has positive influence on user satisfaction which has also a positive influence on organizational performance.

The purpose of this study is to analyze the effects of Logistic Information System on performance by efficiency of internal operation and organizational innovation. The results of this study as follows : The characteristic variable evaluation model that extended from the performance(user's value, perceived usefulness) of Logistic Information System were verified meaningfully. In this study, the efficiency of internal operation and organizational innovation were very important factor, to analyze the effects of Logistic Information System on performance. This study expect that Logistic Information System will achieve their Logistic Information System competitiveness through continuous quality measurement and improvement to increase the performance.

Economic benefits of the dry bottom ash handling system over the wet bottom ash handling system in a new 500MW${\times}$2units pulverized coal thermal power plant in Korea were evaluated. The higher initial capital cost in the dry bottom ash handling system was estimated. However, this higher initial capital costs would be compensated with reductions of the operating cost mainly due to the recycling of bottom ash. Economic analysis showed that the payback period of 4.9 years and the internal rate of return at 21.1% were expected for the additional initial capital cost of the dry bottom ash handling system.

Along with trends of other countries, the Ministry of Information and Communication in Korea decided to operate an Information System Audit Institution for raising qualify of computer network facilitated in state organ and public institution, and to construct effective construction of information system. The aim of the audit institution is applying it to public information business, establishing an information system audit qualification system, and upbringing Private audit organs. The Ministry of Information and Communication realized that although the demand of information system area audit is explosively expanding, the National Computerization Agency cannot satisfies the demand and realize to have audit control for the information of national business as well. The Ministry of Information and Communication plan to enforce the audit on public information business by correlate with information business. The ministry enforce that the supervisory company has major roll to audit and national import business decided by the Information Promotion Committee is subject to have audit control. Therefore, in this paper, the contents of internal audit among internal/external audit will be presented.

After making amendments to archive-related legislations in 2006, the Electronic Records Management Systems (ERMS) were introduced into public institutions. With this, most institutions constructed digital repositories in their records center. In this system, there are several weaknesses that wasted costs and manpower for its introduction and maintenance. The extensibility of a repository is debased, and securing the interoperability is difficult. The study proposed a cloud computing-based model to solve such problems that the previous system had. In particular, this study expected effects through the proposed model. The expected effects are low-cost, highly efficient, extensible, and interoperable in embracing various systems. Thus, the appropriateness of introducing cloud computing into ERMS was analyzed in this study.

Currently, many organizations introduce ERP system as a key enabler of business strategic accomplishment and it can improve productivity and efficiency of organizations by integration and managing enterprise resources. Already many organizations have introduce ERP system and the number of introduced ERP system is increasing steadily. Unfortunately, even though organizations have invested much money, previous studies showed the ERP systems had not always turned in good result. It is easy to find studies that suggest successful implementing strategies for ERP systems. Even if the importance of ERP change management has been emphasized, studies for change management are seldom. This study reviewed the previous literature on strategic use of change management in enterprise. In order to establish a successful implementation of ERP, this paper suggests proper solutions to conduct change management according to implementation phase with activity and output, especially analyzing successful organizations in implementing ERP system through consistent change management.

In the past, ERP had been applied to large company mainly, but recently, in order to exist from global business environment, most of smaller businesses are using or planing to introduce ERP. However, introduction of ERP requires considerable expense and effort, before ERP come into being, it is needed to measure the expense of introducing and the outcome expected. Previous analytical frameworks (according to introduction of ERP) have been focused on measuring improvement of performance by introducing ERP. This study carries out a survey on priority analysis of information system with small businesses which produce displayer parts. To derive the user's priorities which have been disregarded beside the improvement of performance on information system, this study rearranges the analysis indices by using BSC model and it analyzes the priorities of importance according to the stakeholder(manager group, middle manager group, worker group) by using ANP method.

As service utilization for IT technologies such as artificial intelligence, big data, and IOT has recently increased, cloud computing has been introduced to efficiently manage vast amounts of data and IT infrastructure resources that process them to provide stable and reliable information services while streamlining infrastructure costs. Efforts for this are ongoing. This thesis compares and analyzes the operation results before and after cloud adoption in terms of system failures for 426 systems at 360 branches nationwide in cloud systems of companies operating a total of 1,750 cloud systems. As a result of the analysis, the number of failures and failure types , service downtime, etc., the introduction of the cloud yielded significant results in securing service continuity. Through this result, it is expected to provide meaningful implications to companies expecting to secure service continuity by adopting the cloud.
