The objective of the current study was to compare the execution of hygiene and safety management according to the characteristics of children's food service stations, with the ultimate objective of providing sanitary and safe food service to children. To this end, the study conducted surveys of 73 public and private pre-schools with fewer than 100 children in district A from July 30 to October 31 2015. The differences were evaluated by t-test and analysis of variance. The confidence and validity of the results were analyzed by six food ingredient and facilities management questions, three personal hygiene and facilities management questions, four environmental management questions, and five storage and treatment management questions; for a total of 18 questions. The cumulative distribution of the four factors was 61.569%, and the Cronbach's alpha was 0.821, which indicated that the results were reliable. The results revealed that public pre-schools (a) and home-based pre-schools (b) had different levels of food ingredient and facility management, but no differences in the number of cooks, number of children served, type of food distribution, and the existence of mass food service facilities. The results of the study may be used to develop hygiene and safety management manual and educational contents to promote the health of the children served.

Purpose: This study investigated the patient safety culture (PSC), the perception of importance on patient safety management (PIPSM) and the patient safety management activities (PSMA) of care workers in nursing homes. This was a descriptive study that attempted to provide basic data for the patient safety education program of care workers. Methods: Data were collected using questionnaires and interviews from July 1 to 31 in 2020. One hundred and seventy-four care workers participated in quantitative research. The collected data were analyzed by the SPSS/WIN 25.0 program using descriptive statistics, t-test, ANOVA, Bonferroni, and Pearson's correlation. The qualitative data were collected through semi-structured, audio-recorded interviews with six representatives and six care workers from six nursing homes. Content analysis was performed to analyze the data. Results: Positive correlations were observed between PSC and PIPSM, and between PIPSM and PIPSM. Care workers' experience in patient safety management was in the following six categories: "Safety accident risk factors", "Type of safety accidents", "How to prevent safety accidents", "Effective safety management education", "Emphasis on occupational ethics of care workers", and "Needs for standard protocol" Conclusion: These findings indicate that considering the care workers' age and facility size, nurses should enhance patient safety education for care workers and establish a management activity system.

Although the number of chemical accidents has been declining since the Chemical Control Act of 2015, there have been repeated occurrences of similar types of accidents at printed circuit board (PCB) manufacturing facilities. These accidents were caused by the overflow of hydrochloric acid and hydrogen peroxide, which are toxic chemicals used in the printed circuit board manufacturing process. An analysis of the $Cl^-$ content to identify the cause of the accident showed that in the mixed route of hydrochloric acid and hydrogen peroxide, which are accidental substances, the $Cl^-$ concentration was 66.85 ppm in the hydrogen peroxide sample. Through reaction experiments, it was confirmed that the deformation of a PVC storage tank and generation of chlorine gas, which is a toxic gas, occurred due to reaction heat occurring up to $50.5^{\circ}C$. This paper proposes a facility safety management plan, including overcharge, overflow prevention, leak detection device, and separation tank design for mixing prevention in printed circuit board manufacturing facility etch process. To prevent the recurrence of accidents of the same type, the necessity of a periodic facility safety inspection and strengthening of the safety education of workers was discussed.

Road bridges are deteriorating gradually, and it is forecasted that the number of road bridges aging over 30 years will increase by more than 3 times of the current number. To maintain road bridges in a safe condition, current safety conditions of the bridges must be estimated for repair or reinforcement. However, budget and professional manpower required to perform in-depth inspections of road bridges are limited. This study proposes an estimation model for safety rating of road bridges by analyzing the data from Facility Management System (FMS) and Yearbook of Road Bridges and Tunnel. These data include basic specifications, year of completion, traffic, safety rating, and others. The distribution of safety rating was imbalanced, indicating 91% of road bridges have safety ratings of A or B. To improve classification performance, five safety ratings were integrated into two classes of G (good, A and B) and P (poor ratings under C). This rearrangement was set because facilities with ratings under C are required to be repaired or reinforced to recover their original functionality. 70% of the original data were used as training data, while the other 30% were used for validation. Data of class P in the training data were oversampled by 3 times, and Repeated Incremental Pruning to Produce Error Reduction (RIPPER) algorithm was used to develop the estimation model. The results of estimation model showed overall accuracy of 84.8%, true positive rate of 67.3%, and 29 classification rule. Year of completion was identified as the most critical factor on affecting lower safety ratings of bridges.

This study suggests desirable disaster safety education curriculum through analyzing the operational status of the school disaster safety management training course and demand survey of school staff. First, the problem of the disaster safety training course of the school is not connected with the lack of law and system and the school disaster safety job. Second, improvement of law and system and variety of training should be made to acquire professional knowledge. Third, it is necessary to divide curriculum into the following four categories, according to educational needs of public officials ; Educational administration officers course focused on facility safety, maintenance and disaster countermeasure. Educational officials in technical post course addressing approval and permission of school facility projects, seismic reinforcement of school building, etc. Educational supervisors course covering roles and responsibilities of the school safety supervisors in the event of disaster. Teaching staffs course focused on safety instructions for students. Fourth, it is found that lectures and experiential learning methods are the most desirable methods of teaching and learning, and the major ranks are earthquake disaster, fire, gas, typhoon, school road, and electrical safety.

Unpaid Family Worker is blind area of industry safety. Danger of industrial accident is some high but because was excepted in industrial accident compensation insurance application. In most case, because paltry Unpaid Family Worker is no opportunity to take safety education to prevent industrial accidents and there are few safety facility and safety equipment, etc., among business, it may be said that probability to suffer industrial accidents on a trifling mistake or carelessness is higher than general worker of business. Consider such difficult actuality of Unpaid Family Worker and our country must give these benefit of industrial accident compensation insurance application, as opened the door of insurance application in recognition of worker position by "Industrial accident compensation insurance Law" to middle·smaller enterprise's business proprietor or special form labor employees.
