The purpose of this study is to analyze the economic effects of telepresence system for public sector relocation. As a Green IT system, the importance of telepresence is being recognized increasingly as a means to replacing a majority of business trips and thereby reducing greenhouse gases emitted in the process. However, there are only a few related researches that analyze the economic effects of telepresence at the moment. This study conducts the cost-benefit analysis of 157 public sectors which are to relocate from 2012 based on the sample case of National Information Society Agency. The results obtained reveals that telepresence would save about 180 billion won and reduce about 580t $CO_2$ emission. This study are expected to provide the academic framework for organizations contemplating the adoption of Green IT system moving forward.

Recent public information project, which has been organized mainly to large companies is a situation that is being reorganized to small and medium-sized systems integration company. However, many of the small and medium-sized companies lack knowledge of the systematic risk management. Thus, in connection with the revenue, it involves a number of problems. Therefore, in this paper, we present a risk element that occurs mainly in the field of the project, providing a model for measuring the risk element by risk level costs associated with this. Through the convergence, we aim at providing a management system that is able to make the project successfully accomplished, predicting the risk that occurs in advance to pursue the project; Based on the proposed model, it is possible to secure a proper size of reserve fund so it is expected to enable companies to ensure the cost of risk analysis.

It has been an important agenda to acquire effective decision making procedure for various issues occurred in education area. As an example, when it comes for the ministry of education to make a decision on such an issue that proper investment, to enhance information of education area, in national wide elementary schools, an effective decision making procedure will aid to establish right way of investment. Currently, the questionnaires gathered from school teachers or the related professional consultants are the only resources in order for making such a critical and important decision. Recently, however, educational, medical, and financial industries are looking forward the best decision making method integrated with rapidly upgraded modern IT technologies using the various resources and tools which they already possess. With this subject in mind, in this paper we present a generic decision making model applying ADALINE neural network. The model can be easily adapted to various problems arising in education area. We proved the model through simulations with realistic sample data.

Recently, EA has been introduced in the Korean government as a tool for improving both IT management and IT investment. However, EA has been superficially used at the conceptual level without any efforts for facilitating it. As a result, it seems that any substantial outcomes from using EA could be hardly realized. This study suggests EA Service Model as a framework for facilitating the use of EA and then generating benefits. The purpose of EA Service Model is to provide a framework with which information and data can be linked, interconnected and shared in the whole process of IT management. It is expected that EA Service Model will possibly make a contribution to improving IT management. Empirical Analysis shows that key factors of EA Service Model make significant effects on improving the IT management, proving practical value and the validity of the model.

Business performance measurement is used as an important tool to evaluate management performance, control human resources, and implement strategies. It can be measured simply in terms of finance including net profit, return on investment, and return on equity, but this is not sufficient because the performance outside of finance such as internal business process and informatization cannot be examined. Therefore this study defined a KPI(Key Performance Indicators) applicable to local construction companies ranked in the top 30 in construction capability, and also introduced differentiated results from the earlier studies by reflecting more realistic corporate management based on the existing studies and interviews with business experts.

우리 협회는 지난 11월 26일 오후 2시 협회 대강당에서 '건축설계의 국제경쟁력 확보 및 전문화 방안'을 주제로 토론회를 개최하였다. WTO출범과 건축설계시장개방 등 급격한 대내ㆍ외적 환경변화에 처해 있는 우리 건축계의 국제경쟁력 확보 방안을 마련하기 위해 열린 이날 토론회에서는 경쟁력 확보를 위해 건축설계사무소마다 다양한 전문분야를 확보하고, 건축설계 생산성 향상을 위해 설계업계와 구조, 설비 등 관련 전문분야가 협력체제를 구축해야 하며, 건축의 상품성과 문화예술성이 함께 고려된 건설관련 법안이 마련돼야 한다는 주장이 제기됐다. 이날 서울시립대 최찬환교수는 '건축설계의 경쟁력 확보 방안'이란 주제발표를 통해 해외건설업계의 국내진출에 대응하기 위해서는 설계사무소가 전문성과 효율성을 확보해야 한다고 강조하면서 전문영역을 크게 주거, 상업시설, 공공시설, 교육문화시설, 사회복지시설, 교통 및 운수시설 등으로 구분하였다. 최교수는 또 외국업체에 의한 국내시장 잠식을 막고 우리가 해외에 진출하기 위해서는 해외건설업체와 협력해 정보와 기술, 경험 등을 지원받아야 하고 R&D에 대한 투자를 적극적으로 해야한다고 강조했다. 이어 '건축설계의 전문화'에 대해 주제발표를 한 강원대 박경립 교수는 국내 건설관련문제점 개선과 대외경쟁력 강화를 위해 현재 입법추진되고 있는 건설산업기본법이 건축설계의 독자성과 전문성을 고려하지 않고 있다고 지적하면서 이에 대한 보완필요성을 제기하였다. 박교수는 또한 건축설계분야가 갖고 있는 전문성과 함께 '건축문화'라는 사회문화적 측면의 중요성이 인식돼야 한다며 건축의 상품성과 문화예술성이 함께 고려된 건설관련 법안이 마련돼야 한다고 지적했다. 박교수는 이밖에도 사회발전에 따른 새로운 전문영역의 개발로 실내 설계와 도시설계를 예로 들었으며 정보화에 맞게 고도의 전문성을 바탕으로 Network체계를 구축하고 그 핵심은 건축사협회에 정보Network를 구축하여 활용하는 것이라고 제안했다. 한편 주제발표 후에는 약 3시간여에 걸쳐 이문보(동국대 교수), 손세관(중앙대 교수), 이병담(현대산업개발 부사장), 김인호(국방부 건설기술과장), 유경철(삼육건축사사무소 대표), 이관영(본 협회 이사)씨 등 건설ㆍ건축관계자들이 참가한 종합토론이 이어졌다. 이 자리에서는 사회의 인식에 앞서 건축계 내부적으로 전문성과 효율성의 확보에 나서야 한다는 의견과 함께 무한경쟁속에서 우리 건축설계의 경쟁력을 높일 수 있다는 다양한 의견들이 제기되었다. 본지에서는 이번 토론회의 주제발표 내용을 요약 정리하여 게재한다.

In modern information society, the necessity arose of having to manage overall information technology as information technology is introduced to companies and public organizations while the necessity of joining the goals of business and IT is increasing. Also, there has been an increase in organizations which are preventing the overlapping of IT investigations and pursuing ROI. Hereupon, many developed companies created the concept of IT governance. IT governance indicates the structure and dynamic behavior of companies' business and the structural affecting factors influencing IT, and this is expressed as business, the business & IT related committees and departments inside and outside, the framework representing their relationship and range of activity, organizational diagram and process composition. Intermingled with such external factors, the reestablishment of defense IT governance in order to reach the vision and goal of our current military defense has become a requirement. This study aims to describe core strategy for building defense IT governance framework. In order to support these claims, the comprehensive IT governance and information technology are mentioned, domestic and overseas military cases are analyzed, and core strategy for building defense IT governance framework is analyzed as well.

Considering time-lag in the performance evaluation of information system (IS) investment is important because its effect reveals after certain period of time passed. Particularly it is more in the systems of e-government informatization projects which the amount of investment and the scale of business are huge. Many methods to solve this issue have been proposed such as system dynamics methods, simulations, structural equations etc. However, it is still difficult and unsolved problem because collecting practical data for time-lag analysis is very hard. In this paper, we analyze IS time-lag effect through factor analysis using the accumulated practical operational DB data. For the performance evaluation of the G4C system, the representative e-government web portal, we selected eleven factors reflecting time passing in G4C DB data. With these factors this paper conduct time-lag analysis in four view points. First, we conducted 'Stabilizing of G4C system' and got a result that IS is needed about three years for the stabilization. Second, we conducted 'Utilization of G4C system' and got a result that the utilization reaches appropriate level after in three years later after the introduction of G4C system. Third, we conducted 'Cost reduction effect' and got a result that cost reduction is stable in the third year after the introduction of G4C system. Lastly, we conducted 'System maturity effect' and got a result that the system reaches to the quality level that users expect after third to fourth years. According to the results of this research, we found that performance of IS improv continuously not immediately, and it needs three or four years of time-lag.
