Background: The study investigated the causes of safety accidents by facility, focused on safety accidents caused directly or indirectly by school facilities at elementary schools in S City. Purpose: The objective of this study is to provide materials for planning the construction of school buildings and the installation of school facilities and for improving existing facilities and ultimately to minimize mental and Physical losses from safety accidents caused by school facilities and to create pleasant education environment. Method: We selected 10 elementary schools in S City, analyzed the factors of safety accidents caused by facilities inside and outside the schools, and presented the results of the analysis including the factors of safety accidents caused by elementary school facilities. Result: It was found that safety accidents caused by elementary school facilities can be prevented to some degree by considering safety accidents in facility planning. As the safety accident rate is higher at elementary schools than at middle and high schools, it is essential to consider safety accidents in planning the construction of an elementary school and to execute safety accident prevention education in order to reduce safety accidents at elementary schools. In addition, as the curriculums are revised and new facilities are introduced for the new curriculums, elementary students' physical, psychological and environmental factors should be analyzed and studied closely and the results should be reflected in establishing the standards for the installation of elementary school facilities.

Whenever a disaster occurs, people emphasizes that "Safety management is most important thing in the company". However, a situation of safety management is not changed dramatically after accidents in the past. Many small-and-medium sized industries neglect the importance of safety management. Current situation can be easily figured out when looks up an occurrence rate of accident, accident frequency rate and intensity rate. This paper investigated what workers of hotel-related industries think of a safety and types of accidents, effect of a safety education. On-site-survey was conducted for actual workers in four deluxe hotels and one condominium. 207 persons out of 400 people were replied. Statistical analysis was performed with SAS package about their reply. In injured type, cut from knife was most frequent. Main cause of accident was a unsafe posture and a unsafe behavior, so more safety education for these workers are necessary. In a physical pain which related with job, chronical pain was most dominant. As a result, a safety education has a high correlation with an experience of injured and treatment of safety, Cooking department has highest occurrence of accident than any other departments. Workers with an experience of five to ten years have most lowest treatment of safety, aid of safety education, safety feeling of their working environment, so peer attention must be put on these people to reduce accidents.accidents.

Background: The high sensitivity of individuals toward safety information in production activities, that is, attentional bias toward safety (ABS), can positively predict safe behaviors. It has become a hot topic in current organizational safety behavior research. However, there is no literature on its modification method. Methods: Based on the modified dot-probe task, we designed a modification training method of ABS. The training method required subjects to respond to the location of detection points that presented after safety stimulus and neutral stimulus pictures. Subjects' attentional bias values of safety and neutral pictures were measured during the experiment. Twenty-one students were selected and divided into a control group and training group to gain comparable results. Results: A novel training method was developed in this study to promote the efficacy of safety stimulus by activating ABS of the subjects. Moreover, repeated trainings and preacquired relative knowledge can enhance this effect. Conclusion: This study develops an experimental approach to evaluate the effectiveness of safety education and safety training, and also provides a new research idea for accident prevention.

As our whole society has become increasingly aware of safety and emphasizes the importance of preventing safety accidents, the airline cabin service sector is also facing a strong demand to improve practical system for aviation safety education. In this regard, the development of appropriate safety education programs and the getting of human resources who can develop and operate such programs are becoming key issues. This study aims to provide academic and practical implications for safety education and training in airline cabins by reconfirming the importance and direction of safety education in the context of airline cabin services, and by specifying and establishing qualification requirements for personnel who develop and operate such safety programs. To this end, we review the content that should be included in safety training programs, the qualifications required of developers, managers, instructors, and examiners who develop or operate such programs, and how safety training programs can be continually improved as relevant conditions change in the future. In addition, we have also suggested ways to train appropriate managers, instructors, and examiners, including improving the compensation system for them, and how to effectively manage trainees. In order to secure a higher level of aviation safety in the future, it will be necessary to continue research on the development of more diverse and high-quality aviation safety education programs and the training of related personnel.

The purpose of this study is to explore how adolescents' psychological characteristics affect their sense of life safety according to gender. To this end, a survey was conducted on male and female high school students in six schools in the C area, and a total of 1,048 data were used for analysis. Differences in major variables according to gender were verified, and the effect of psychological characteristics on living safety awareness was analyzed through hierarchical multiple regression analysis. As a result of the analysis, depression, anxiety, type A characteristics, and the presence or absence of experience in accidents did not significantly affect life safety awareness in the male student group. On the other hand, in the female student group, anxiety and type A characteristics had a significant effect on life safety awareness. Anxiety negatively affects living safety awareness, and type A characteristics have been shown to have a positive effect on living safety awareness. The presence or absence of depression and accident experience did not significantly affect life safety awareness. The results of these studies suggest that gender differences should be considered in education to prevent life safety awareness and that education that reflects the psychological characteristics of adolescents is necessary.

Objectives: The purpose of this study was to seek measures for improvement and management of farm work safety and health by conducting questionnaire surveys and on-site investigations to ascertain the present state of occurrence of safety accidents and safety and health management levels among swine farmers. In particular, the purpose of this study is to provide basic data for the establishment of measures for the management of safety and health suitable to the characteristics of related working environments. Methods: Questionnaire surveys were conducted among 223 farmers engaged in swine farming in 14 regions, and 10 farms were visited in order to implement multilateral methods, including in-depth interviews, along with field surveys. Results: The surveys indicated that 26.2% of all respondents experienced farm-work related safety accidents and body-reaction related accidents showed a high ratio at 31.1% of all respondents. With regard to cause materials of safety accidents, work other than that directly related to swine raising showed high ratios of safety accidents, with pigsty facility related accidents at 26.6%. Although most workers recognized the dangers latent in the working environments, their behavior and responses to the prevention of safety accidents were still insufficient due to a lack of understanding of safety and health management. In the survey on the present state of personal hygiene and wearing of protective equipment, workers were found to have been exposed to dangerous and harmful environments both inside and outside pigsties, but the actual states of their wearing protective safety equipment were very poor. Conclusion: Given the results of this study, swine farmers well recognize problems in their control of safety accidents and management of safety and health, but their knowledge about safety and health education and management guidelines was insufficient. Therefore, safety and health education, public relations, and customized personal protective equipment suitable for swine raising work should be developed in order to address the foregoing problem.

According to own investigation conducted by Korea Gas Safety Corporation Gas Safety Research Institute in 2017, the length of underground pipes in domestic high-pressure gas pipelines is approximately 770km, of which 84% is buried in Ulsan and Yeosu industrial complexes. In particular, 56% of underground pipelines have been in operation for more than 20 years. This suggests urgent management of buried high pressure gas pipelines. PHMSA in US and EGIG in Europe, major causes of accidents in buried gas pipelines are reported as third party damage, external corrosion and loss of pipe wall thickness. Therefore, it is important to evaluate whether the defects affect the remaining life of the pipe when defects occur in the pipe. DNV and ASME have evaluated the residual strength of pipelines through the hydraulic rupture test using pipe specimens with artifact flaws. Once the operating pressure is known through the residual strength of the pipe, the wall thickness at the point at which the pipe ruptures is calculated. If we know the accurate rate of corrosion growth, we can predict the remaining life of pipe. In the study, we carried out experiments with A53 Grade.B and A106 Grade.B, which account for 80% of domestic buried pipes. In order to modify the existing model equation, specimens with a defect depth of 80% to 90% was tested, and a formula expressing the relationship between defect and residual strength was made.

Objectives: Along with the several cases of pulmonary disorders caused by exposure to indium that have been reported in Japan, China, and the United States, cases of Korean workers involved in processes that require handling of indium compounds with potential risk of exposure to indium compounds have also been reported. We performed biological monitoring for workers in various target manufacturing processes of indium, indium oxide, and indium tin oxide(ITO)/indium zinc oxide(IZO) in domestic factories. Materials: As biological exposure indices, we measured serum concentrations of indium using inductively coupled plasma mass spectrometry, and Krebs von den Lungen 6(KL-6) and surfactant protein D(SP-D) using enzyme-linked immunosorbent assays. We classified the ITO/IZO target manufacturing process into powdering, mixing, molding, sintering, polishing, bonding, and finishing. Results: The powdering process workers showed the highest serum indium level. The mixing and polishing process workers also showed high serum indium levels. In the powdering process, the mean indium serum concentration in the workers exceeded $3{\mu}g/L$, the reference value in Japan. Of the powdering, mixing, and polishing process workers, 83.3%, 50.0%, and 24.5%, respectively, had values exceeding the reference value in Japan. We suppose that the reason of the higher prevalence of high indium concentrations in powder processing workers was that most of the particles in the powdering process were respirable dust smaller than $10{\mu}m$. The mean KL-6 and SP-D concentrations were high in the powdering, mixing, and polishing process workers. Therefore, the workers in these processes who were at greater risk of exposure to indium powder were those who had higher serum levels of indium, as well as KL-6 and SP-D. We observed significant differences in serum indium, KL-6, and SP-D levels between the process groups. Conclusions: Five among the seven reported cases of "indium lung" in Japan involved polishing process workers. Polishing process workers in Korea also had high serum levels of indium, KL-6, and SP-D. The outcomes of this study can be used as essential bases for establishing biological monitoring measures for workers handling indium compounds, and for developing health-care guidelines and special medical surveillance in Korea.
