The purpose of this study was to assess the hygiene status of 145 child-care foodservices, which were newly registered in the Center for the Children's Foodservice Management (CCFSM) in Changwon, Gyeongnam. Sanitary inspection checklist (40 food safety items) of Korea Food and Drug Administration (KFDA) was used by the CCFSM in Changwon, Gyeongnam. Average score from the total safety items in 145 child-care foodservices was 21.41 points out of 40 points. Score gaps between the lower group (71 foodservices, 13.92 points) and higher group (74 foodservices, 28.61 points) showed a significant difference (P<0.001). The top five priorities of sanitary measures needing corrective actions for child-care foodservices were as follows: 'provide hand washing and sanitizing tools, and supply manuals on how to wash hands properly', 'supply record form for access/inspection', 'conduct education for cooks on standards in the selection of sanitizer for raw vegetables and proper methods to wash and sanitize raw vegetables', 'provide a refrigerator and a freezer with installed thermometers and temperature record monitoring logs', 'encourage separation of contamination operating zone and clean zone or conduct training for cooks on ways to prevent cross-contamination by performing work separately by the hour'. For the higher group, most were national/public facilities (83.3%), whereas in the lower group, private facilities (62.1%) were more common than national/public ones (37.9%). Therefore, a significant difference (P<0.001) was detected in the two groups. These private facilities should be supported.

According to the Laboratory Safety Act, each laboratory in the field of science and technology must conduct safety inspections and diagnosis every year or every two years. At present, the relevant guidelines are not clear, so there is a high possibility that inspection and diagnosis will become ineffective. In the laboratory, there is a pre-risk factor analysis system for hazardous factors, but there are many difficulties in implementation due to lack of education and understanding of the researchers, excessive work, etc. For the analysis of the opinions of experts in the safety field using the Delphi technique, we analyzed the following items: 1. Consideration in applying the Lab Safety Act, 2. Consideration in Lab Safety inspection and diagnosis, and 3. Government policy necessary for Lab. safety. Through the investigation and analysis of the detailed items, we extracted for problems and alternatives in current laboratory safety diagnosis and current law.

The quality inspections items such as loss on drying, total ash, and acid-insoluble ash contents in herbal medicines, have a correlation with external sources of pollution, but are not themselves hazardous factors. Z-scores for standard normal distribution were used to investigate herbal medicines requiring quality control, which exceeds the regulatory limits of quality inspection. In total, 7,773 samples were analyzed based on plant parts. For the loss on drying, the numbers of items of herbal medicines requiring quality control are like these; 15 items for above-ground parts and 5 items for underground parts. For the total ash, 21 items for above-ground parts and 4 items for underground parts. For the acid-insoluble ash, 8 items for above-ground parts and 1 item for underground parts.

This study is for the purpose of studying the validity of the construction of items and grading of the evaluation table at clinical practice used as the method of evaluation when clinical practice of Dept. of Dental Technology. 205 dental technicians in 4 cities were questioned to analyze the relation between items of the evaluation table at clinical practice and its grading. The collected materials were inspected by SAS V8 for Windows. The results are as follows: 1. Making up all the items and grading seem to be appropriate because they had the marks more than midium(more than 3.28). 2. Making up detailed items and grading seem to be trusted because they had the marks more than 3.30. 3.The significance level of the relation between items of the evaluation at clinical practice and its grading by t-inspection is p<0.0001 and so it appears to be meaningful. 4. It proved to be meaningful in result of regression analysis of the influence on the construction of the evaluation at clinical practice and its grading. With this result, further study is needed for the better methods of the evaluation in its adjustment and graduated grading among the items.

The safety management cost system under the Construction Technology Promotion Act has contributed greatly to the prevention of construction accidents according to the chronological changes and social demand, but various problems have been pointed out. The biggest problem is that the safety management cost is earmarked very low because other items of safety management costs except for the safety inspection are not appropriately included in the actual construction site. Furthermore, it has been pointed out that it is difficult to settle the orderer due to the lack of specific use criteria. Therefore, in order to secure the proper safety management cost, this study is to estimate the actual cost by using of specification, quantity, material cost, labor cost for each type of the safety management item The results of this study were compared with the 71 cases of safety management costs in the safety management plan. In addition, analysis of unclear or unnecessary items in the current safety management cost and criteria and suggestions for improvement are provided. It is hoped that the results of this study will contribute to the rational safety management rate calculation.

To prevent the electrical accidents in the laboratory, we identify problems for periodic inspections of the electric field and develop a fuzzy inference system that can be practically applied to check items. Focusing on electrical safety in the lab environment, we draw check items that can be applied in common and develop a standard checklist that is consistent with the laboratory electrical safety and the periodic inspections. Using the standard checklist we select the items that may contain a linguistic ambiguity and define the membership functions for these items. We also have a safety rating defined by the membership function. Using these fuzzy variables we form the fuzzy rules in the form of 'If-Then' and develop a fuzzy inference system through the fuzzy engine. From this, electrical accidents could be prevented in advance continuously by managing the intelligent and efficient inspection and electrical safety to prevent the electrical accidents in the laboratory.

BIM and AR technologies have been assessed as a means of enhancing productivity within the construction industry, through the provision of effortless access to critical data on site, achieved via the projection of 3D models and associated information onto actual structures. However, most of the previous researches for applying AR technology in construction quality management has been performed for construction projects in general, resulting in only overall on-site management solutions. Also, a few previous researches for the application of AR in the quality management of specific elements like reinforcements focused only on simple projection, so conducting specific quality inspection was impossible. Hence, this study aimed to develop a practically applicable BIM-based AR quality management system targeted for reinforcements. For the development of this system, the reinforcement inspection items on the quality checklist used at railway construction sites were analyzed, and four types of AR functions that can effectively address these items were developed and installed. The validation result of the system for the actual railway bridge showed a degradation of projection stability. This problem was solved through model simplification and enhancement of the AR device's hardware performance, and then the normal operation of the system was validated. Subsequently, the final developed reinforcement quality inspection system was evaluated for practical applicability by on-site quality experts, and the efficiency of inspection would significantly increase when using the AR system compared to the current inspection method for reinforcements.
