최근 정보 시스템의 기능이 복잡화, 거대화하고 있는 추세에 따라 감리인이 수작업으로 시험시나리오를 작성하고, 검증시험을 실시하는 것은 매우 비효율적이라고 할 수 있으며, 결과로 얻어진 증적 자료는 신뢰성 및 객관성 면에서 한계를 가지게 된다. 정보시스템 감리의 시험단계에 대하여 적정한 시험도구를 도입 ${\cdot}$ 적용함으로써 감리 시행의 효율성을 제고하고 정량적인 판단 근거를 제시하여, 감리 의견의 신뢰성 및 일관성을 확보하는데 도움이 될 수 있다. 본 연구에서는 감리서비스요인이 감리품질과 감리성과간의 관계에 미치는 영향과 이들과 자동화 도구 적용의 적합관계를 규명하고, 나아가서 감리품질과 감리성과간의 관계를 규명하고자 하였다. 연구결과, 자동화 도구가 감리품질에 유의한 영향요인이며, 또한 감리품질은 감리성과에, 그리고 자동화 도구의 적용이 감리성과에 유의한 영향을 미치는 것으로 밝혀졌다.

감리는 정보시스템의 품질을 향상시키기 위한 일련의 활동들 중 하나로 독립된 제3자가 정보시스템 구축 및 운영에 관련된 각종 위험 및 통제 상태를 점검하고 평가하여 개선이 필요한 사항을 권고하는 것이다. 그러나, 대부분의 평가가 감리인의 전문적 경험 및 주관적 판단에 의존한 정성적 방법으로 수행되고 있어 중요한 위험을 간과할 문제점을 내포하고 있다. 이에 따라, 본 논문에서는 다양한 비정형 산출물을 DTD와 스키마를 포함한 XML메타 모델인 표준포맷을 생성 후 단계별 필 통합적 방법으로 의미분석을 실시하여 자동으로 위험요소를 식별하고 평가할 수 있는 위험평가 프레임워크, 위험평가 모델, 위험평가 기준을 제안한다. 이와 같은 시스템화된 감리품질 개선기법을 통하여 추출된 결과는 감리인에게 사전에 전달됨으로써 감리노력과 일정을 절약할 수 있어 효율적인 감리수행 및 효과적인 감리결과가 보장된다.

This research proposed a model for automatically monitoring the quality of insulation adhesive application in external insulation construction. Upon case implementation, the area segmentation model demonstrated a 92.3% accuracy, while the area and distance calculation accuracies of the proposed model were 98.8% and 96.7%, respectively. These findings suggest that the model can effectively prevent the most common insulation defect, insulation failure, while simultaneously minimizing the need for on-site supervisory personnel during external insulation construction. This, in turn, contributes to the enhancement of the external insulation system. Moving forward, we plan to gather construction images of various external insulation methods to refine the image segmentation model's performance and develop a model capable of automatically monitoring scenarios with a considerable number of insulation materials in the image.

This study proposed vision artificial intelligence-based automated supervision technology for external insulation and finishing system, and basic research was conducted for it. The automated supervision technology proposed in this study consists of the object detection model (YOLOv5) and the part that derives necessary information based on the object detection result and then determines whether the external insulation-related adhesion regulations are complied with. As a result of a test, the judgement accuracy of the proposed model showed about 70%. The results of this study are expected to contribute to securing the external insulation quality and further contributing to the realization of energy-saving eco-friendly buildings. As further research, it is necessary to develop a technology that can improve the accuracy of the object detection model by supplementing the number of data for model training and determine additional related regulations such as the adhesive area ratio.

소프트웨어를 개발할 때 작성되는 명세서들은 개별특성으로 인해 연속적인 자동화가 이루어지지 않으며, 소프트웨어 감리에서도 많은 불일치 항목이 발견된다. 본 논문에서는 분석 및 설계단계에서 작성되는 명세서간 불일치를 검출하기 위해 시스템 개발과정에 대해 실시한 감리결과 보고서를 분석하여 불일치가 발생하는 연관된 명세서를 내용별로 분류하고, 이를 바탕으로 분석, 설계, 테스트 단계별로 사용되는 명세서간 불일치 추출방안을 제안한다. 이를 이용하면, 분석 및 설계단계에서 작성되는 명세서의 오류를 줄임으로써 최종산출물인 소프트웨어에 대한 품질을 향상시킬 수 있다.

Accomplishing information system, techniques, methodology have been studied continuously and give much help to auditors who are using them. Additionally audit report which is the conclusion of accomplishing ISA(information system audit), has law of a basis and phase with ITA/EA Law(Electronic Government Law). This paper is for better quality of ISA report. But it has more errors about sentence and Grammatical structures. In this paper, to achieve quality improvement objectives, it is necessary to recognize the importance of an audit report by investigating on objectives, functionality, structures and usability of a report firstly, and a legal basis, the presence of report next. Several types of audit reports were chosen and the reports errors were divided into several categories and analyzed. After grasping reasons of those errors, the methods for fixing those errors and check-lists model was provided. And based on that foundation, the effectiveness validation about real audit reports was performed. The necessity for efforts to improve the quality of audit reports was emphasized and further research subject(AI Automatic tool) of this paper conclusion. We also expect this paper to be useful for the organization to improve on ISA in the future.

Information system audit, by checking overall matters about constructing and managing information system, has to contribute to improvement of information system's quality and improving performance of projects. For this, an auditor has to present objective corroborative facts which back up result of audit and ways of improvement, but in reality, general(especially businessmen's) cognition is that audit is biased by way too subjective opinions. Local experience and theoretical research until now propose that tools of automating audit will be an active means of systematically collecting and proposing these objective evidences of audit. This research not only verified that in the field of audit, phenomenon of technology application can be explained and predicted by applying TAM, but it also contributed in extending theoretical base on information technology and audit by distinguishing several characteristics which appear in the process of the model's application and analysis.

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 specifications which are drawn up when developing a software cannot achieve continuous automation because of individual qualities of them, and many inconsistent elements can be discovered even from software audit. In this paper, we establish the standards for the classification of inconsistent items by analysing audit related data in order to maintain the consistency among specifications drawn up in the phases of analysis and design. We propose the specification inconsistent item detection method. This can reduce the error of the specification which is drawn up from analysis and design phase with it will be able to improve the quality of the software which is a last product. It can improve the quality of the software which is a last product, by reducing the error of the specification which is drawn up from analysis and design phase.

The rebar detailing is an important work influencing the final performance and quality of RC structures. But it is one of the most irrational and illogical activity in construction site. Many groups of workers, including main contractors, structural engineers, shop drawers, rebar fabricators, and etc., participate in this activity. A loosely-organized process for this activity is apt to produce a big amount of rebar loss or even degraded structures. A 3-dimensional rebar auto-placing system, called as Rebar Hub, has been designed and implemented in this research. Rebar Hub provides a totally integrated service from 3D structural modeling of buildings to rebar auto-placing considering anchorage, splice, and the length of ordered rebar. In addition, Rebar Hub can recognize the 2D drawing CAD files and then build 3D structural models which are used for the start point of 3D rebar auto-placing. After rebar auto-placing, each members of the 3D structural model have rebar information belonging to them. It means that the rebar information can be used for the afterward works such as quantity-survey, manufacturing and fabrication of rebars. Rebar Hub is showing outstanding performance while applying to practical projects. It has almost five times productivity and reduces the rebar loss up to 3~8% of the initially-surveyed amount of rebar.
