  • 소프트웨어의 품질은 요구사항 품질과 강하게 관계되어 있다. 이에 따라서 기업들은 요구사항의 품질을 향상시켜 주기 위한 노력을 하고 있다. 그러나 명세서 형태의 요구사항은 검증하기 어려우며, 분석가의 비정형화된 업무 지식에 의존해야 한다. 또한 명세서 형태의 요구사항 품질을 향상시켜 주기 위한 정형화된 방법론이나 자동화된 기법이 미흡한 상황이다. 본 논문에서는 요구사항의 품질을 향상시켜 주기 위한 요구사항 검증 프로세스 및 자동화 검증 도구를 제안한다. 검증을 위해 요구사항에 대한 외적뷰 설계와 내적뷰 설계를 비교한다. 사례연구를 통해 제안된 요구사항 자동화 검증 기법의 타당성을 검증한다.

  • In automotive industries, reusability of product information is increasing through database construction of previous product data. The product data is stored by data quality management in product information systems. For naval ships, have the functional similarity by the ships of the same classification and class, that are built by series. Information of hull structures as well as embarked equipments are similar. So it would be effective to use database systems that are considered product information quality of previous ships in design and production processes. In this paper we discuss product information quality in database construction of naval ship product models. For this, we propose a basic concept and reference model for data quality verification. Based on this concept, A verification guideline is defined and it is applied for the case study of the digital naval ship which was built to the naval ship product model.

  • Among many automotive manufacturing processes, an assembly process has the smallest automatization percentage. As the correct assembly of the supplied components according to its specification is directly related with the quality of the final product, it is of the utmost importance to reduce the possible human errors in the assembly line. However, due to the lack of an effective verification system for an assembly line, currently, there is huge cost loss caused by the errors in seat assembly every year. Therefore, in this paper, to overcome the limit of the current verification method and to prevent the occurrence of assembly errors caused by mismatching assembling components or its specifications, a verification system and its method is proposed employing the RFID technology. The system is for automatic detection of the assembly errors, so that it can reduce the time and effort needed for verification and maximize the work efficiency. Also, by preventing the assembly errors in advance, the productivity can be increased through a quality innovation.

  • The Railroad Safety Act's regulation reads as follows. "The Minister of Construction and Transportation may qualify and authorize the product to guarantee performance and safety of parts, machine, and device used in Railway fields." Another regulation reads as follows."“The guidelines about targets, standards, and procedures of Quality and Authority in first provision are decided as Ministry of Construction and Transportation Decree." The software used in rail cars and facilities is considered as a railway product. Therefore, it is qualified and authorized for acquiring the safety of rail cars and facilities. The software businesses shall again a Quality and Authority for applying a software to the rail cars and facilities. This paper regulates some guidelines that are needed to develop a software. The procedures that a software developer performs are divided by plan, requirement, design, implementation, and maintenance. The procedures that a software verification person performs are classified by verification plan, requirement verification, design verification, implementation verification, testing verification, maintenance verification, and safety activity. The entire processes and detailed activities to develope and verify a software are described as new guidelines.

  • 국내외에서 건축시설 중심의 BIM 라이브러리를 개발하여 보급하고 있으나, 개별 라이브러리 형상에 대한 물리적, 논리적 품질검토 방법을 정의하고 있지 않아 2D로부터 변환된 3D 라이브러리 모델의 신뢰성을 확보하는데 어려움이 있다. BIM 라이브러리는 자재 및 부재 제작업체들이 참여하여 컨텐츠를 구성하므로 개별 라이브러리의 제작 후 납품시 별도의 품질검토를 통해 인증을 받는 절차가 무엇보다 중요하다. 또한 그 활용에 범용성을 가져야 하므로 일관된 검토기준에 따라 객체의 품질을 확보하는 것이 필요하다. 따라서 본 연구에서는 국토교통부 표준도를 기반으로 작성된 토목분야 BIM 라이브러리를 토대로 기존 2D와 비교하여 물리적 및 데이터 관점에서 정확한 라이브러리 객체가 작성되었는지를 확인하기 위한 품질 검토 방법을 구성한다. 본 연구는 건축 및 토목분야의 자재 및 부재 제작업체들이 BIM 라이브러리 객체 납품 시 품질 검토 방법으로 널리 활용될 수 있을 것이다. 또한 As-Built BIM 모델의 품질검토를 위한 룰-셋(Rule-Sets) 정보로 활용되어 파라미터 기반의 자동화된 품질검증 시스템 구축에 활용될 수 있을 것이다.

  • 우리 해군은 함정 제품모델(Naval Ship Product Model, NSPM)을 중심으로 하는 협업 제품개발 환경 구축을 통해 설계 데이터의 재사용성과 M&S의 활용도를 높이고 있다. 그 결과 설계결과의 신뢰성이 높아지고 있으며, 이를 활용한 운영, 건조 시뮬레이션을 통해 소요군의 요구사항이 면밀히 반영되도록 하는 연구도 진행 중에 있다. 이에 따라 설계 데이터의 DB 구축 및 그 품질에 대한 중요성이 부각되고 있으나, 그와 관련된 연구는 초기상태에 머물러 있는 실정이다. 본 연구에서는 저자들의 선행연구 결과인 함정 제품모델의 품질검증 방법론에 기초하여 함정 제품모델을 구성하고 있는 형상요소의 구체적인 품질검증 방안과 이를 자동화하기 위한 연구를 수행하였다. 함정 제품모델 데이터 중 상대적으로 중요하며, 검증과정에 많은 시간이 소요되고 있는 선각모델을 사례연구 대상으로 정의하였으며, 자동차산업에서 사용되고 있는 제품데이터품질(Product Data Quality, PDQ)을 형상검증 기준으로 활용하였다. 최종적으로 선각모델의 형상 품질검증을 위한 기준과 알고리즘을 제안하였으며 이에 기반 한 초기 시스템을 개발하였다.

  • The purpose of this study is to find specific service quality factors of enterprises that can maximize the perception of banks' services to users of commercial banks in China, and to establish empirically how these quality factors affect the bank's image. They also want to verify the impact of the positive image of the bank on the user's satisfaction and the willingness to use the bank's services. For empirical verification of this study, questionnaires will be used to customers who have used the services of each of the four commercial banks in China, and the survey was conducted. The collected data were analyzed using the SPSS using statistical techniques such as Cronbach' ${\alpha}$, Investigative Factor Analysis, Reliability Analysis, Correlation Analysis, Regression and Difference Verification. The results of the verification were summarized below. First, the quality of service of commercial banks has a partial positive effect on the bank's image. Second, the image of a commercial bank has a positive effect on customer satisfaction. Third, the image of a commercial bank has a positive effect on the purpose of use. Fourth, the image of commercial banks has a partial mediated effect between service quality and customer satisfaction. Fifth, the image of a commercial bank has a partial mediated effect between the quality of service and its intended use.

  • The user increases around the WiBro and in which the mobile broad band service is the wireless internet base technology HSDPA, that is the cellular phone foundation technique, and moreover the issue about the user effective quality guarantee emerges but the quality control of the wireless network is the incomplete actual condition. Therefore, the reliability verification according to the development of the system for the performance measure for the continued wireless data service and it and evaluation are needed for the quality control. In this paper, the wireless data service quality measurement system was implemented with the design. The same test environment as the existing network performance measurement program was built for the reliability verification of the embodied device for measuring quality and evaluation and the cost performance was performed. It could confirm that design and embodied wireless data service quality measurement system operated accurately in this paper through the quality measure result value analysis.

  • The purpose of this study was the improvement and modification of the HACCP verification checklist in school foodservices. For this, the HACCP verification checklist was modified on the basis of an existing school foodservice format. The modified checklist was composed of 28 items, including CCPs (critical control points), microbial test, and other components of the HACCP system than CCPs. To confirm the suitability of the modified checklist, comparisons were made based on the microbiological quality of cooked foods, utensils, and number of aerial microbes in the working area. In this study, the applicability of the modified checklist was determined by focusing on cooked squid with seasoned fresh vegetables (Ojingeochaesomoochim). The following results were obtained from 14 schools in Changwon. The checklist scores for maintaining hot foods over $60^{\circ}C$ or serving within 2 hours, microbial tests of drinking water, food contact surfaces and cooking utensils, monitoring tools, and usage of suitable sanitizers were 2 points each (The possible highest score is 2 points). On the contrary, the checklist score for microbial test of cooked foods was the lowest of all the items. The correlation coefficient (r) between the improved checklist and microbiological quality of cooked foods was 0.699 (P<0.01), whereas that between the improved checklist and microbiological quality of cooking utensils was 0.612 (P<0.05). The correlation coefficient between the improved checklist and aerial plate count in the working area was -0.556 (P<0.05). Our results indicate the potential possibility of using the HACCP verification checklist in school foodservices.
