In the design of the metal forming processes, various types of ductile fracture criteria are used to predict crack initiation and to fabricate metallic products without any defects. However, the quantitative measurement method for determination of crack initiation is insufficient. It is very difficult to detect crack initiation in ductile metals with excellent deformability because no significant load drop is observed due to crack generation. In this study, the applicability of acoustic emission sensors, which are commonly used in facility diagnostics, to measure crack initiation during the metal forming process was analyzed. Cylindrical notch specimens were designed using the finite element method to induce a premature crack on the surface of pre heat-treated steel (ESW90) material. In addition, specimens with various notch angles and heights were prepared and compression tests were carried out. During the compression tests, acoustic emission signal on the dies and images of the surface of the notch specimen were recorded using an optical camera in real time. The experimental results revealed that the acoustic emission sensor can be used to detect crack initiation in ductile metals due to severe plastic deformation.

To establish a radioactive waste life cycle history management system, a series of processes including waste generation, classification, packaging, storage, transportation, and disposal were reflected in the information management system. A preliminary review process was introduced to reduce the amount of radioactive waste generated and manage it efficiently. Through this, the amount of radioactive waste generated must be checked from the beginning of the research, and the generated radioactive waste must be thoroughly managed from the stage of generation to final disposal. In particular, in the case of radioactive waste data generated during nuclear facility operation and each experiment, a radioactive waste information management system must be operated to receive information from the waste generator and integrate it with processing information at the management stage. The application process for small-package containers was reflected so that information such as the generation facility of radioactive waste, generation facility, project information, types of radioactive waste, major radionuclides, etc. In the radioactive waste management process, the preceding steps are to receive waste history from the waste generators. This includes an application for a specified container with a QR label, pre-inspection, and management request. Next, the succeeding steps consist of repackaging, treatment, characterization, and evaluating the suitability of disposal, for a process to transparently manage radioactive wastes.

The Computer-assisted Hazard Analysis and Critical Control Point(HACCP) program has been developed for a systematic implementation of HACCP principles in identifying, assessing and controlling hazards in institutional foodservics operations. The HACCP-based sanitation evaluation tool has been developed, based on the results of the computerized assisted HACCP program in 4 service sites of C contracted foodservice company, including 2 general hospitals with 650-beds, one office operation of 400 meals per day, and one factory foodservice of 1,000 meals per day. All database files and processing programs were created by using Unify Vision tool with Windows 95 of user environments. The results of this study can be summarized as follows : 1. This program consists of the pre-stage for HACCP study and the implementation stage of the HACCP system. 1) The pre-stage for HACCP study includes the selection of menu items, the development of the HACCP recipe, the construction of product flow diagrams, and printing the HACCP recipes and product flow diagrams. 2) The implementation of the HACCP system includes the identification of microbiological hazards, the determination of critical control points based on the decision tree base files. 3) The HACCP-based sanitation evaluation tool consisted of 3 dimensions of time-temperature relationship, personal hygiene, and equipment-facility sanitation. The Cronbach's alphas calculation indicated that the tool was reliable. The results showed that the focus groups rated the mean of importance in time-temperature relationship, personal hygiene, and equipment-facility sanitation as 4.57, 4.59 and 4.55 respectively. Based on the results, this HACCP-based sanitation evaluation tool was considered as an effective tool for assuring product quality. This program will assist foodservice managers to encourage a standardized approach in the HACCP study and to maintain a systematic approach for ensuring that the HACCP principles are applied correctly.

The purpose of this study was to examine the effects of food safety management support in the Center for Children's Foodservice Management (CCFSM) on foodservice facilities for children in Busan area. We assessed the status of hygiene and safety practices of institutional and non-institutional foodservice on a quarterly basis by using an inspection checklist for food hygiene and safety developed by dieticians from February to December in 2013. The subjects were 103 children's foodservices, including 37 institutional and 66 non-institutional foodservices. Inspection checklist consisted of nine categories with 39 checklists; general characteristics, personal hygiene, ingredient control, menu planning, cooking processing control, serving management, washing, disinfection and storage control, and environment and safety management. The average score of each field (pre-supporting/post-supporting) in institutional foodservice was 0.56/0.92 for personal hygiene, 0.55/0.87 for ingredient control, 0.76/0.97 for menu planning, 0.53/0.89 for processing control, 0.27/0.67 for serving management, 0.47/0.91 for washing, disinfection and storage control, and 0.61/0.91 for environment management and 0.64/0.94 for safety management. In non-institutional foodservice, the average score of each field (pre-supporting/post-supporting) was 0.49/0.80 for personal hygiene, 0.52/0.75 for ingredient control, 0.78/0.97 for menu planning, 0.42/0.76 for processing control, 0.32/0.61 for serving management, 0.57/0.88 for washing, disinfection and storage control, and 0.46/0.82 for environment management and 0.73/0.88 for safety management. The average scores of all categories (pre-supporting/post-supporting) were 0.57/0.91 in institutional foodservice and 0.53/0.82 in non-institutional foodservice. The effects of management support in CCFSM on institutional foodservice were higher than those of non-institutional foodservice. Based on these results, we found that management support in CCFSM on foodservice facilities for children had a significantly positive effect on status of hygiene and safety practice regardless of foodservice facility size.
