  • 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.

  • BIM libraries for architectural projects have been developed and distributed. However, they do not define physical and logical quality control methods for individual library objects, so there are some difficulties in securing reliability of 3D library models converted from 2D drawings. Because the BIM library contents can be built by participating material and member-fabrication companies, after making individual BIM library objects, a certification process through separate quality verification is very important when delivering as-built BIM libraries. Since the BIM library should have generality for usage, it is necessary to secure the quality of BIM library objects according to consistent verification standards. Therefore, this study suggests a quality verification method for certifying a BIM library object from physical and data perspectives by comparing existing 2D drawings in the BIM libraries built based on standardized 2D drawings from MOLIT. This method could be widely used for quality verification in delivering BIM libraries by companies in the construction sector and operated with rule set data for quality verification of as-built BIM models.

  • Recently, R.O.K. Navy is increasing re-usability of design data and application of M&S(Modeling and Simulation) through the establishment of collaborative product development environment focused on Naval Ship Product Model(NSPM). As a result, the reliability of the result of design is getting better, and furthermore, a study to improve quality of construction through simulation of production/operation is in progress. Accordingly, the database construction of design data and the DB(Database) quality become important, but there was not research related to those or it was just initial state. This paper conducted research about system of the quality verification process of shape elements which compose NSPM based on the quality verification guideline of NSPM as the result of the precedent study. The hull surface was limited as verification object. The study to verify two things that application of basic drawing by the cad model of hull surface, and whether there is error in the geometric quality of cad model was progressed.

  • 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.
