The dynamic resistance monitoring is one of the important issues in that in-process and real time quality assurance of resistance spot weld is needed to increase the product reliability. Secondary dynamic resistance patterns, as a real manner, are hard to adapt those factors in real time and in-plant system. In the present study, a new dynamic resistance detecting method is presented as a practical manner of weld quality assurance at the primary circuit. By the correlation analysis, it is found that the primary dynamic resistance patterns are basically similar to those of the secondary. Various dynamic resistance indices are characterized with the primary curve. And quality of the weld, like the tensile shear strength, is estimated using adaptive neuro-fuzzy estimation system which is consisted of the Sugeno fuzzy algorithm. Through the fuzzy clustering and parameter optimization, real time weld quality assurance system with less efforts is proposed.

As consumer, one of the most important things how to get manufactured good is an assurance of quality. We have a consumer protection law which is weaker than product liability law(so called PL law), but stronger than civil law. In this special issue, we want to explain PL law which will be legislated within not long time and to propose a method of protection and defence in building and housing field. As the quality control of constructor, ISO 9000 series for quality assurance and CM (Construction Management) for quality assister are concerned in all construction process. Therefore, above mentioned PL law is very serious problems which are applied in apartment housing, if applied, a little part as not real estate will be possible.

Client-supplier collaboration has been an imperative approach to new product development (NPD), in which a good product specification management system and practice is crucial to the assurance of product quality. This study investigates product specification management in client-supplier collaborative NPD. Based on the interviews and survey study, 12 problems and 13 good practices of product specification management are identified. It also compares the importance and degree of the implementation of the product specification practices in Hong Kong electronics industry. The results suggest that more intensive practices should be implemented for better product specification management.

Purpose: The distribution of goods and the flow of information, determined by consumer behavior toward online shopping, is drastically popular worldwide. This study examines some factors such as brand trust, online sales promotion, consumer personality, delivery service, quality assurance, information search, and online consumer satisfaction influence online shopping behavior. Research design, data, and methodology: A constructed questionnaire in an online survey was conducted with 241 random cluster respondents in the greater Jakarta Area. Structure equation model was utilized to analyze and verify all the data. Results: Research finding indicates online sales promotion, delivery service, quality assurance, and online consumer satisfaction positively influence information search. Meanwhile, brand trust, quality assurance, and information search positively influence online shopping behavior. However, the result illustrates that consumer personality negatively influences both information search and online shopping behavior. Conclusions: To influence online shopping behavior, the most important factors that need to be considered by marketplaces are quality assurance. It positively motivates Indonesia's citizens to collect information and make unplanned purchases. The study finding can be a reference for brands to maintain and build outstanding product quality, an informational website, and an excellent marketing strategy so that customers can meet their expectations. Besides, it also broadens both companies' and individuals' knowledge about the digital revolution on consumer behavior.

It is the greatest task to prescribe accurately and concretely consumer's needs of qualities into the product standards in an enterprise manufacturing and sailing products, From this point of view, Quality Function Deployment system is introduced to inguire into the establishing method of product standards closely Above all, the decision of quality characteristic in the product standards and the estblishing method of product standard are introduced to satisty in this repord. Applying to the product standards in Qulity Function Deployment system, frst it is systematically brought quality function to consumer's needs of qualities into the products. Second the method is concerned with quality function assurance applied in induction of product quality. Also it is available to establish method of product quality level in almost every company.

The product process is sequence of all the required activities that a company must perform to develop, and manufacture a product. These activities include marketing, research, engineering design, quality assurance, manufacturing, and a whole chain of suppliers and vendors. The process also comprises all strategic planning, capital investments, management decisions, and tasks necessary to create a new product. manufacturing processes must be created so that the product can be produced in the product facility Purchasing new equipment and training workers may be required if new technology is to be used. Tools, fixtures, and the sequence of steps in the manufacturing processes must all be developed to allow rapid, high-quality, cost effective production. Also, it may be needed to be rearrange the production facility to adapt to the new manufacturing processes. Therefore, this study tries to proposed that Scheduling by customer needs group for minimizing the problem and reducing inventory, product development time, cycle time, and order lead time.

군수품의 품질보증을 담당하는 국방기술품질원에서는 크게 4가지 형태로 군수품을 구분하여 품질보증 활동을 수행하고 있다. 이러한 군수품에 대한 품질보증형태 분류는 품질보증기관의 입장에서만 결정되었기에 다른 이해관계자라 할 수 있는 방위사업청, 제조업체 및 수요군에서 요구되는 분류 기준과 상이할 수 있다. 이에 본 논문에서는 군수품에 대한 효율적인 조달 및 생산, 품질보증을 위한 적정 군수품 품질보증 형태 분류 기준을 제시하고자 하였다. 이를 위해 군수품에 대한 정부 품질보증기관인 기품원 뿐만 아니라 정부 조달물자의 품질확인을 담당하는 한국조달연구원의 품목 분류제도에 대해 살펴보았다. 또한 방사청 등 계약 및 제조, 품질보증, 수요군 등 모든 관련기관 입장에서의 적절한 군수품 분류기준을 정의하고 분석하였으며, 현 기준에 따른 군수품 분류 데이터 현황을 파악하였다. 아울러 제시된 품질보증형태 분류 기준을 활용한 적용사례 역시 제시하였다. 끝으로 본 연구에서 제시된 품질보증 형태 분류 기준을 적용한 차등화된 정부 품질보증 활동을 통해 업무 효율성 개선을 통한 군수품 품질향상에 기여할 것으로 판단된다.

Purpose: Nowadays, the risk assessment system is widely used in many industrial and public areas to reduce the possible risks. The system is used to determine the priorities of the government quality assurance works in Defense Agency for Technology and Quality. However, as the risk assessment system is used for other purposes, there are some items that need improvement, and in this study, we propose improvement plans by benchmarking the risk assessment systems of other institutions. Methods: In this paper, first, the procedures of risk assessment system used in many industrial sites were reviewed, and how each institution specialized and applied the system. Afterwards, by benchmarking various risk assessment systems, an improvement plan on how to operate the risk assessment system in the case of government quality assurance for centrally procured military supplies was presented, and practical application cases were presented to prove the usefulness of the improvement plan. Results: The proposed risk assessment system differs from the existing system in five major aspects. First, inputs, outputs, and key performance indicators were specified from the systematic point of view. Second, risk analysis was analyzed in four dimensions: probability of occurrence, impact, detection difficulty. Third, risk mitigation measures were classified, control, transfer, and sharing. Fourth, the risk mitigation measures were realized through document verification, product verification, process verification, and quality system evaluation. Finally, risk mitigation measures were implemented and the effectiveness of the risk mitigation measures was evaluated through effectiveness evaluation. Conclusions: In order for the risk assessment procedure proposed in this study to be applied to actual work, it is necessary to obtain the consent of the person involved in the work due to the increased time for risk identification and preparation of the government quality assurance log, and a change in the information system that performs the actual work is required. Therefore, the authors of this study plan to actively perform internal seminar presentations and work improvement suggestions to apply these research outputs to actual work.
