  • The Apartment Defect Dispute Mediation Committee of the Ministry of Land, Infrastructure, and Transport received as many as 7,686 complaints regarding defects in 2021, and the conflict caused by these disputes on the defects is worsening. A quality inspection team system was established in January 2021 to address the deepening conflict, and this system prevented the emergence of defects in apartment houses before the residents moved in. Quality inspections were conducted based on the Housing Act standards, but the reality is that the standards for the ordinances are not systematic. Based on the analysis of the ordinances by the apartment quality inspection team, 23 out of 226 local governments utilized the quality inspection teams, and they had different standards for the quality inspection subjects and inspection periods. In addition, the inspection standards for the defect checklists used by the apartment quality inspection teams operated by local governments varied. A survey was conducted by apartment quality experts to tackle this problem and proposed improvement plans for the defect checklists used for the quality inspection of apartment houses.

  • In order to intensify an enterprise competition, quality inspection controls are very important issue. An organization or division of a company hopes which to acquire the quality inspection information be updated in real-time with respect to shop floor. In this paper, we develop a quality inspection control system for a Turbine/Generator production industry. The system compromises inspection scheduling module related to shop floor control (SFC) system, formal documentation control module, and formal inspection control module. In the quality inspection control system, ORACLE RDBMS is used for the database management system and ORACLE DEVELOPER 2000 is used for system development tool. The characteristic of this system is to support so it can enhance productivity and quality through inspection plans related to production scheduling.

  • It is worthwhile to know how the quality inspection is practised to assure the product quality for the export articles, and what problem is resulted from the current quality inspection system for the export articles. The aim of this paper is to survey the status of quality inspection system for the export articles and to design the quality inspection system for the export articles so as to not only solve the problems arising from the current system but also improve the product quality for the export articles. To find out the facts the survey is conducted by sending a prepared questionnaire both to the export industries and to the export quality inspection agencies authorized by the Ministry of Commerce and Industry. The export industries surveyed are selected to provide broad representation with respect to the type of industry as well as to the size of company. The survey shows that about 50 percent of the responding industries desire to discontinue the current quality inspection system for the export articles, and other 50 percent of them desire to continue it until all the export industries can make the best use of quality control techniques.

  • The variable sampling inspection scheme with screening for the purpose of assuring the upper limit of maximum expected surplus loss after inspection has been proposed. In this inspection scheme, it has been assumed that a product lot consists of products manufactured through a single production line and lot quality characteristics follow a normal distribution. In the previous literature with respect to inspection schemes, it has been commonly assumed that lot quality characteristics obey a single normal distribution under the condition that all products are manufactured in the same condition. On the other hand, the production line is designed in order that the workload of respective processes becomes uniform from the viewpoint of line balancing. One of the solutions for the bottleneck process is to arrange the workshops in parallel. The lot quality characteristics from such a production line with the process consisting of some parallel workshops might not follow strictly the single normal distribution. Therefore, we expand an applicable scope of the above mentioned variable sampling inspection scheme with screening in this article. Concretely, we consider the variable sampling inspection with screening for the purpose of assuring the upper limit of average outgoing surplus quality loss in the production lots when the lot quality follows the mixed normal distribution.

  • On this research, recognizing that ship inspection and audit services are closely related in Improving ship safety, the importance of active quality managements of ship inspection and audit services have been notified. For this research, based on previous research results, Quality managements of ship inspection and audit services were divided into the following aspects; the source of quality managements, execution of quality managements and outcome of quality managements. The results of this study is as follows. Overall, it is clearly shown that the elements of quality managements execution such as management responsibilities, resource management., product realization, measurement and analyzation, and improvement had also acted as a mediator between the relation of quality managements source and outcome.

  • The method of lot by lot quality protection for sampling inspection by variables is widely used in quality control. In case of sampling inspection being done repeatedly, one can use the information from the previous sampling inspection to improve current estimates. This article shows that empirical Bayes estimator is superior to the usual sample mean in repeated sampling inspection by variables.

  • The inspection policy and inspection error are very critical factors which influence the outgoing quality. In other words, such factors influence the acceptance rate of the incoming matarials. Hence, the outgoing lot size is varied. This paper presents a method to compute the break-even point(pb1, pb2) under these two factors, which canbe used to determine the economic acceptance inspection type.

  • The present study proposed three inspection reliability indices which compared inspection results evaluated at in-depth(routine) inspection and in-depth safety inspection; Nominal inspection reliability index, Real inspection reliability index, and DS nominal inspection reliability index. The methods to improve the inspection reliability were also proposed. Since bridge inspection process is critical to ensuring the safety of bridges and identifying repair and maintenance needs, the quality of the inspection data produced from the inspection process is very important. Consequently, the inspection reliability indices were suggested to evaluate quality of current inspection practices. Specifically, approximately 85% of inspection errors evaluated by the DS nominal inspection reliability index are within 1 rating grade(equal to or less than damage score ${\pm}0.1$). In order to improve the inspection reliability, transportation agency should implement QC(Quality Control) practices and develop professional expertises of inspectors by higher requirements for inspectors, on-off line inspection training and etc.
