This research explores the potential of leveraging unstructured data from construction supervision documents, which contain detailed inspection insights from independent third-party monitors of building construction processes. With the evolution of analytical methodologies, such unstructured data has been recognized as a valuable source of information, offering diverse insights. The study introduces a framework designed to assess cost performance by applying advanced analytical methods to the unstructured data found in final construction supervision reports. Specifically, key phrases were identified using text mining and social network analysis techniques, and these phrases were then analyzed through binomial logistic regression to assess cost performance. The study found that predictions of cost performance based on unstructured data from supervision documents achieved an accuracy rate of approximately 73%. The findings of this research are anticipated to serve as a foundational resource for analyzing various forms of unstructured data generated within the construction sector in future projects.

정보화 시대를 살아가면서 더 많은 조직들이 업무에 있어서 정보의 중요성을 인식하고, 대부분의 조직들은 정보시스템을 주된 기능으로 대체하는데 기초를 둔 컴퓨터 환경으로 변화시킬 계획들을 가지고 있다. 하지만 많은 조직들은 정보시스템의 효율성과 신뢰성을 조사할 필요가 있고 심지어 불평까지 하는 경우도 있다. 오늘날 정보시스템 감리에 대한 수요는 정보시스템의 성공적인 개발을 지원하기 위해 증대하고 있다. 감리의 목표는 정보시스템의 부작용을 막고, 예산의 효율적인 사용을 확신하며 조직의 내부 감리 능력과 인식을 제공하는 것이다. 이런 목표를 성취하고 감리 품질을 높이기 위하여 정보시스템 감리를 제도화하고 공공부문의 정보시스템 감리현황을 조사하고 개선할 필요가 있다. 이 연구에서는 우선 감리와 선행연구, 우리나라 현황 등을 기술한다. 그리고 공공부문 정보시스템 감리의 개선방안을 제시하고자 한다.

Web applications are widely used by the development of the Internet, but there are no separate audit model for a web-based information systems. Information business has a wide variety of characteristics. So, web-based information system audit model is needed. Therefore, a web-based information system audit model was proposed to enhance the effectiveness of audit and to increase the quality. Audit check lists were applied based on three sets of existing information audit check framework. An audit point of time was defined as analysis, design, and implementation. An audit domain was defined as contents, design, and process. Moreover, audit viewpoint and inspection standards were defined by setting standards of process, product, and performance. Moreover, this paper proposes differences between an existing model of information system development methodology and web-based information system. It also deduced audit checklists according to audit domains for web-based information system audit. The deduced audit checklists were verified for its suitability by conducting surveys, and the modified audit inspection model, in which the deduced audit checklists were applied, was proposed.

ASP서비스는 사용기업의 데이터를 외부의 데이터센터에 위치시키고, 데이터에 대한 사용권만을 제공하는 극단적인 외주 형태의 서비스이다. 따라서 ASP서비스는 보안문제와 서비스 제공업체의 신뢰성 문제가 어떤 형태의 정보시스템보다 크게 부각된다. 이러한 ASP서비스에 대한 신뢰성과 효율성 확보를 위한 감리 프로세스는 필수적일 것이다. 본 논문에서는 ASP서비스에 대한 감리 프로세스를 제안한다. 우선, 기존의 정보시스템 감리의 정의를 통하여 ASP감리의 정의를 도출하고, ASP프레임워크를 제안하며, 제안된 프레임워크에 따른 통제항목을 설정한다. 마지막으로 검증단계에서 ASP감리 프레임워크를 기존의 정보시스템 감리 프레임워크와 비교분석하고, ASP서비스 수명주기 세부활동 별 통제항목의 중요도를 산출한 설문을 통해서 통제항목의 타당성을 검증한다.

An information System Audit by the recognition of a problem and suggestions for solutions for overall matters about constructing and managing information systems is needed in order to contribute to the improvement of an information system's quality and improving the performance of projects. In reality, however, the general cognition is that audit is biased by subjective opinions. For this, an auditor needs to measure the level of recognition of the usability and convenience of the technologies of automating audit by applying TAM in the information system audit, and to analyze the relationship with recognition and availability of the interested parties for the technology (tool) of the audit. By the hypothesis verification result, an auditor needs to present objective corroborative facts that back up the level of recognition and usability for the information technology in the field of audit. This study verified that the phenomenon of technology application can be explained and predicted by applying TAM in the field of audit. Through an empirical study of the recognition level of audit and contractor, the developer suggests that the audit plan stage is similar to the audit corrective action stage, but the audit action stage is different from the audit review stage. This research can verify the audit technology preferred for the availability and intention of use and usability.

The user interface is the medium, which provides the users to have an access to the web-based information system. The user interface is the means of improving usability and accessibility for the user, as well as being the core component in the web-based information system. In this paper, the audit framework of the user interface was developed to upgrade the usability and accessibility; it was based on the three basic components of the current audit framework in the web-based information system. At the time of an audit, the UI process of the 'Analysis', 'UI Design', 'UI Production', and 'Test' was defined, which was analyzed through the web development methodology. Also, for the area of an audit, the 'Information', 'Design', and 'Technology' were defined by the analysis of the components that makes up the user interface, From the view of an audit, the standard criteria of an assessment were set as 'Usability', 'Accessibility', and 'Cross Browsing'. Through the framework that was proposed in this paper, practical audit applies the performed examples. By this, the efficiency of the proposed framework was verified.

The development of a UIS driven by muncipal governments has been expanding through the wide application of GIS since NGIS project initiated. City of Inchon has developed a sewage management system as the first-year product of the long-term UIS project. GIS auditing process has been adopted to secure the credibility and stability, and to minimize the critical failure factors for building the sewage management system. So far, the auditing method generally used for developing information system in general purposes has been applied to the GIS field due to the absence of proper method for GIS auditing only. This study proposes major differentials in terms of the auditing between GIS and general information system based on the results from auditing Inchon´s sewage management system. The major results from this study would contribute to the establishment of the methodology and accompanying documents for the proper GIS auditing.

This thesis suggests fixed quantity model and detailed performance procedures of an information system audit. In addition, an identification of the check-items with high operating risk and factors that might lead to serious effects on the business are made. Then, this thesis proposes the information system audit model that can grant priorities. By using this model, the orderer can evaluate objectively with digitized mark. The model can improve the effectiveness, reliability, and objectivity of the audit by minimizing the discrepancies of different opinions about audit evaluation results between auditee and the orderer. The proposed model is adapted to an application system and audit projects of the database construction. As a result, the model has received an equal mark from the result of the general reviews, thus the propriety of the proposed model was verified.

As buildings are changing variously from the side of use, efficiency and size, the construction qualities are more importantly recognized. Supervision system was enacted in the Residential Building Law in 1990 and responsibility supervision system in the Construction Engineering Management Law in 1994, respectively. However, recently revised supervision system in 2003 has some limitations: the present problems of appointing supervisor, disposing the supervisors, supervisor's works. Therefore, the aim of this study is to improve the present supervision system for mix-use residential building. By implementing the proposed revised supervision system, it will be able to expect quality improvement, confidence of the owner and the user, development of construction technology, and increase international competitiveness of supervision company.
