Strarting with Buyeong Apartment in Dongtan-2 disrict in 2017, collective complaints of residents are frequently occurring due to low quality problem such as improper construction and defects of apartment houses. Because of this, the Ministry of Land and Transport is preparing a comprehensive improvement scheme to improve the quality of Apartment Housing(AH), taking into account the continuing complaints from the residents of AH and the problem raised by the National Assembly. The basic profile of the improvement scheme is induce the tenants and experts to discover and point out defects that are repaired until the date of use inspection or due date. For this purpose, we suggested this defects management system linkaged by the preliminary inspection and quality inspection system for prospective occupants. In this context, this paper aims to suggest an effective likage method between the preliminary inspection of prospective residents and the quality inspection system implemented by local governments as an ordinance.

The 3D scanning technology is being introduced for quality inspection of building construction. Therefore, this study tried to confirm whether it is possible to check the quality of rebar by using 3D scanning. After rebar placed on the formwork slab was scanned with a 3D scanner, the rebar spacing was confirmed by overlapping with the CAD drawing. As a result, the 3D scanner was able to check the quality of rebar work on one floor at a time. Therefore, 3D scanning could be used for quality inspection of rebar works such as columns, beam and girders, walls, and slabs in the future.

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.

This study is centered on the combined use of LiDAR(Light Detection and Ranging) and AR(Augmented Reality) technologies during vertical and horizontal frame measurements in construction projects. The intention is to enhance the quality control procedure, elevate accuracy, and curtail manual labor along with time expenditure. Present methods for accuracy inspection in frame construction often grapple with reliability concerns due to subjective interpretation and the scope for human error. This research recommends the application of LiDAR and AR technologies to counter these issues and augment the efficiency of the inspection process, along with facilitating the dissemination of results. The suggested technique involves the collection of 3D point cloud data of the frame utilizing LiDAR and leveraging this data for checks on construction accuracy. Furthermore, the inspection outcomes are fed into a BIM (Building Information Modeling) model, and the results are visualized via AR. Upon juxtaposing this methodology with the current approach, it is evident that it offers benefits in terms of objective inspection, speed, precise result sharing, and potential enhancements to the overall quality and productivity of construction projects.

정보화 사회로의 급속한 전환으로 인해 고품질 소프트웨어에 대한 관심과 요구가 증대되었다. 따라서 양질의 소프트웨어를 확보하여 시스템의 안정성과 신뢰성을 높이 위해서는 개발활동의 전 단계에서 품질 보증 활동 및 평가가 이루어져야 한다. 개발 초기에는 프로젝트의 특성과 품질요구사항을 철저히 파악하여 품질목표를 설정하고 개발단계에서는 품질목표의 충족여부를 면밀히 점검하여야 한다. 본 논문에서는 소프트웨어 품질 평가의 기준이 되는 ISO 9126을 기반으로 소프트웨어 개발 전 단계에대한 품질특성의 상관관계와 가중치를 설정하고, 정량화된 품질평가 모텔을 제안하여 소프트웨어 개발의 성공에 실질적으로 지원할 수 있는 평가기준 정립 및 표준화를 위한 기초로 활용할 수 있다.

This study developed a model to evaluate the quality management system of a medical device manufacturing company, and applied it to medical device manufacturers to understand the impact on business performance in response to international regulations and industry's change. This study prepared preliminary items, defined four (4) major factors (Plan-Do-Check-Act) that consist of the evaluation layers and items per category according to prior research review and expert interview, and calculated the weight and importance using AHP. The study results showed that responsibility & authority and quality objective in Planning Category, product-related requirement and R&D in Doing Category, Measuring and monitoring in Check Category, and review of meeting Regulatory and regulation in Action Category are relatively more important factors. The evaluation model developed based on the calculated weight and importance to business performance was applied to medical device manufacturers to investigate and analyze the implementation level of QMS and its impact on business performance according to each category. Most medical device manufacturers to be studied showed a reasonable level of QMS and effective business performance. Almost all the evaluation layers and items in the four (4) factors had a significant influence on business performance. Although the medical device quality management system is aimed mainly at license acquisition, it is important that management environment factors not related directly to licensing and authorization are important to business performance, and it is effective when these factors are integrated and operated within and outside the manufacturer.

오늘날 바이오 정보처리 소프트웨어의 품질은 각종 보안장치의 성능과 신뢰성을 좌우하는 중요한 요소로 자리잡고 있다. 국내의 경우, 아직 바이오 정보처리 소프트웨어에 대한 품질특성, 특히 신뢰성에 관한 품질평가와 인증이 자리잡지 못한 실정이며 평가와 인증을 위한 시험 인증체계가 구축되어 있지 않은 실정이다. 이로 인해, 바이오 정보처리 소프트웨어의 품질저하로 인한 생체인식 분야의 보안성 및 신뢰성 저하를 유발할 수 있는 문제점이 발생할 수 있다. 본 연구에서는 ISO/IEC 12119와 ISO/IEC 9126을 기반으로 바이오 정보처리 소프트웨어의 품질요구를 체계화하고 신뢰성 중심의 바이오 정보처리 소프트웨어 시험모듈과 시험모듈 적용을 위한 점검표를 구축하였다.

공공시설에 대한 안전점검은 공공시설의 노후화에 따라 정기적인 검사의 필요성이 요구되고 있다. 기존의 안전점검 방식은 대부분 육안으로 점검하는 것에 의존하는데 이는 점검자의 숙련도에 따라 결과의 품질이 달라지게 된다. 본 논문에서는 XAI 기반의 공공시설물 건전도 안전검사 평가시스템을 제안하며, 이는 점검자의 숙련도와 무관하게 항상 같은 결과를 도출해 내며 XAI 를 통해 사용자에게 안전점검에 대한 결과를 제시해준다. 공공시설물 중 터널 시설물의 안전검사 평가시스템을 기반으로 하는 연구를 진행하였으며 이는 수정없이 교량 시설물 등 다른 공공시설물에 적용이 가능하다. 본 논문은 5 가지로 구분된다. 1) 터널 이미지와 균열에 마스크를 적용한 이미지 두 가지의 데이터 셋을 448x448 로 생성한다. 2) UNet 과 Resnet152 의 두 모델을 적용한 혼합 모델을 이용하여 생성한 데이터 셋을 훈련시킨다. 3) 훈련된 혼합 모델에서 생성된 분할 이미지에 대해 노이즈 제거 과정을 진행한다. 4) 노이즈 제거가 끝난 이미지에 스켈레톤화(Skeletonization)를 적용시켜 균열 이미지의 뼈대를 구한다. 뼈대 이미지 기반으로 균열의 길이, 두께, 위치등의 정보를 얻는다. 5) XAI 부분에서는 뼈대 이미지의 정보를 토대로 균열의 위치, 두께, 길이 등에 대해 계산을 진행한 후 사용자에게 제시해준다.
