2002 년 미국의 회계부정 문제에 기인해 감사조서의 작성 및 수정, 보관에 관한 규정이 강화되었다. 따라서, 회계감사의 일부로 수행되는 전산감사도 이 규정에 따라 전산 감사조서의 작성이 강화되었다. 최근 정부는 공공기관에서 발주하는 일정규모 이상의 정보화 프로젝트에 대한 감리를 의무화하였으며, 공공부분의 정보시스템 감리는 점차 확대되어 감리시장이 성숙단계에 이르는 것으로 평가되고 있다. 본 연구에서는 정보시스템 감리수행 결과를 평가하기 위한 감리조서의 구성방안을 제안한다. 기존 감리보고서의 불분명한 감리전략과 감리 결과를 지지하는 증거가 불충분한 문제점을 보완하여 감리전략에 기반한 감리조서의 구성을 제안한다. 이는 기존의 감리절차 진행과정에 감리조서 작성을 추가/보완함으로써 기존의 감리절차를 유지하면서도 감리보고서의 신뢰성을 증진한다.

Since 1995, national and local governments have competitively initiated many and large GIS projects and audit for the projects becomes an important issue. So far, the audit in the Information Technology(IT) area has tried to deal with the issue but ineffectiveness has been found for the successful GIS project management. Effective auditing is a critical element for the project management. In order to establish a proper audit model for the GIS projects and to promote auditing activities in the projects, this study constructs two hypotheses and tries to prove them. The hypotheses are as follows : 1) For a good audits model for GIS, unique characteristics of a GIS project audit items and the scope of the audit need to be identified. 2) The scope of audit needs to be classified according to the requests from tasks in the projects. To prove the hypotheses, this study analyzes positive aspects of audit in IT and construction projects, clarifies the audit items in GIS projects by comparing with them, and classifies the scope of the GIS audit based on various types of GIS projects. As a results, 5 types of the GIS audit are identified : (1) audit for project management, (2) audit focused on IT, (3) audit characterized by GIS technologies, (4) GIS database audit and (5) consulting services for critical problems in the projects. In addition, 4 criteria in classifying the GIS projects are suggested for the GIS audit. The 4 criteria are domain, scope, duration, and GIS applications technologies. Especially, GIS technology considered in this study includes GIS software, methodologies for GIS development, GIS database and quality control of GIS data, which are not usually reflected in the existing studies about in GIS audit. Because the GIS audit depends on a type of GIS projects, scopes of the audit can be flexibly reconstructed in accordance with the types of GIS projects. This is a key to effective and realistic audit for the future GIS projects. Strategies for effective GIS audit are also proposed in terms of the following: GIS project management, goal establishment in each audit stage, documentation from GIS audit, timing strategies for intensive GIS audit, and designing team structure.

최근의 정보 시스템 감리수요는 공공부문을 중심으로 매우 빠르게 증가하여 점차적으로 민간부문으로 확대되고 있는 추세이다. 이는 정보 시스템 감리를 통해 정보 시스템의 품질 향상을 기대할 수 있기 때문이며, 향후에도 조직의 정보시스템에 대한 의존도가 증가할 것 이므로, 정보시스템의 효과성, 효율성 및 보안성은 더욱 중요한 문제로 대두 될 것이며, 따라서 시스템 감리의 중요성은 높아질 수 밖에 없을 것이다. 그러나 아직 정보시스템감리는 이러한 기대에 부응하기 위한 체계적 기술분야로 정립되지 못하고 있으며, 그 원인으로서는 분석 결과의 객관적 증거 확보를 통한 감리 결과의 신뢰성 제고가 미흡한 것이 제기되고 있다. 이는 정보시스템 감리가 다분히 주관적인 요소에 의해 수행되며 이로 인하여 감리인과 피감리인 간의 의견 상충이 다수 발생되며, 이러한 갈등은 감리의 효과성을 크게 저하시키고 있다. 본 연구 이러한 문제를 극복하기 위해 다양한 문헌 고찰을 통해 실질적인 계량적 감리 접근방법을 제시하고자 한다. 본 연구에서 제시된 방법론 실무에서 유용하게 쓰일 수 있으며, 이러한 노력은 우리나라의 감리 품질 제고에 큰 도움이 될 것이라 생각한다. 또한 이러한 계량적 데이터 추후 감리 연구의 기초 자료로 활용될 수 있어 감리 연구에도 많은 도움이 될 것이다.

CM services have been increasingly practiced over the two decades in the Korean construction industry, and recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of holistic research to investigate current status and future direction of CM industry in Korea. In this context, the purposes of this study are 1) to analyze current status of Korean CM industry in terms of owners, market, CM firms, contracts, and work scopes, 2) to define different types of CM practices, and 3) to propose growth models for Korean CM firms based on the defined CM project types. An extensive literature review and statistical analysis of 2012 CM contracts were performed in order to analyze the CM status. Based on the analyses, ten different CM types are defined, and growth paths of CM firms are illustrated. Implications and lessons learned during the statistical analysis and workshops are briefly introduced as well.

Korea's construction engineering companies are facing difficulties in deterioration of international construction profitability because they focus on traditional engineering fields such as design and construction supervision. Therefore, it is necessary to strengthen competency of high-add-value engineering field such as Project-Management-Consultancy (PMC). This paper aims to suggest the strategies to enhance the international PMC competency. This study identified the competency factors for international PMC, using Borich needs assessment and Locus for focus model. As a result, step-by-step strategies were suggested according to the competency level in domestic engineering companies. The results of this study will assist Korean engineering companies to consider the important competencies for international PMC projects. Furthermore, enhancement strategies are going to be proper references for domestic engineering companies which prepare the international PMC project.

Many studies have been conducted on asset management of public facilities, as the importance of such management has been increasing. This basic study aims to present strategies for the practical use of public asset management, and seeks to propose efficient management and utilization measures from a cost perspective by comparing and analyzing the importance and impact relationship between cost items for public asset management. In this study, 19 sub-items and the top 4 items were chosen by deriving cost factors based on the previous literature. A survey was conducted, and the results of the survey were analyzed by using the Analytic Hierarchy Process(AHP) and Interpretive Structural Modeling (ISM) methods. The AHP was used to derive the priority between items, and ISM was used to identify major groups and mutual influences. As a result, those items showing both high priority and high importance, such as user cost, dismantling/disposal cost, replacement cost, maintenance/repair cost, etc. are determined as priority items to be considered for public asset management of public facilities. Also, it is necessary to minimize the impact on other items in public asset management by those items which are impacted less by other items but have significant impact on the items such as initial construction costs, conceptual design costs, construction costs, and supervision costs. It is expected that the results and analysis methods presented in this study can be used to provide strategies for asset management of public facilities.

Recently, as the growth of the wireless Internet, PDA and HPC, the focus of research and development related with GIS(Geographic Information System) has been changed to the Real-Time Mobile GIS to service LBS. To offer LBS efficiently, there must be the Real-Time GIS platform that can deal with dynamic status of moving objects and a location index which can deal with the characteristics of location data. Location data can use the same data type(e.g., point) of GIS, but the management of location data is very different. Therefore, in this paper, we studied the Real-Time Mobile GIS using the HBR-tree to manage mass of location data efficiently. The Real-Time Mobile GIS which is developed in this paper consists of the HBR-tree and the Real-Time GIS Platform HBR-tree. we proposed in this paper, is a combined index type of the R-tree and the spatial hash Although location data are updated frequently, update operations are done within the same hash table in the HBR-tree, so it costs less than other tree-based indexes Since the HBR-tree uses the same search mechanism of the R-tree, it is possible to search location data quickly. The Real-Time GIS platform consists of a Real-Time GIS engine that is extended from a main memory database system. a middleware which can transfer spatial, aspatial data to clients and receive location data from clients, and a mobile client which operates on the mobile devices. Especially, this paper described the performance evaluation conducted with practical tests if the HBR-tree and the Real-Time GIS engine respectively.

Recently, two international standard organizations, ISO and OGC, have done the work of standardization for GIS. Current standardization work for providing interoperability among GIS DB focuses on the design of open interfaces. But, this work has not considered procedures and methods for designing GIS DB. Eventually, GIS DB has its own model. When we share the data by open interface among heterogeneous GIS DB, differences between models result in the loss of information. Our aim in this paper is to revise the design guidelines for geographic information databases in order to make consistent spatial data models, logical structures, and semantic structure of populated geographical databases. In details, we propose standard guidelines which convert ISO abstract schema into relation model, object-relation model, object-centered model, and geometry-centered model. Furthermore, we provide sample models for applying these guidelines in commercial GIS S/Ws. Building GIS DB based on design guidelines proposed in the paper has the following advantages: the interoperability among databases, the standardization of schema definitions, and the catalogue of GIS databases through.
