Through the survey on the current status of hazardous substances in laboratories, the research institute is designed to establish measures to improve the management of university laboratories and to create a safe laboratory. We intend to explore countermeasures by confirming and reviewing the recognition of the statutes in the "Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" through the questionnaire. Although there are various parts to create a pleasant environment for a laboratory, the most important part is the role of a laboratory manager in the area where each and every one of the laboratory's directors is the "Act on the Establishment of a Safety Environment in a Laboratory", but if the laboratory is not to be accident-prone, the laboratory's responsibility is to be more secure. This research is intended to be funded by research to reasonably implement" Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" before applying to universities and to protect field-based research activities and to reasonably reduce safety accident prevention and risk.

The purpose of this study is to analyze neighborhood environmental factors affecting bicycle accidents and accidental severity in Seoul, Korea. The use of bicycles has increased rapidly as daily transportation means in recent years. As a result, bicycle accidents are also steadily increasing. Using Traffic Accident Analysis System (TAAS) data from 2015 to 2017, this study uses negative binomial regression analysis to identify neighborhood environmental factors affecting bicycle accidents and accidential severity. The main results are as follows. First, bicycle accidents are more likely to occur in commercial and mixed land use areas where pedestrians, bicycle and vehicles are moving together. Second, bicycle accidents are positively associated with road structures such as four-way intersection. In contrast, three-way intersection is negatively associated with serious bicycle accidents. The density of speed hump or street tree is negatively associated with bicycle accidents and accidential severity. This finding indicates the effect of speed limit or street trees on bicycle safety. Fourth, bicycle infrastructures are also important factors affecting bicycle accidents and accidential severity. Bicycle-exclusive roads or bicycle-pedestrian mixed roads are positively associated with bicycle accidents and accidential severity. Finally, this study suggests policy implications to improve bicycle safety.

In this study, we suggested the direction to lower the risk by analyzing the risk factors for each process for the hydrogen refueling station to be installed in Chungju. HyRAM, one of the quantitative risk assessment tools for hydrogen gas, was used to analyze the hazards. By evaluating the frequency of accidents and consequences for each process, the most dangerous processes and accident factors were presented, and the risk mitigation factors were synthesized. Hydrogen refueling stations are currently in the global infrastructure expansion period, and the lack of accident data could be an alternative to this risk assessment and is expected to be used as a reference for the future expansion of hydrogen refueling stations.

The airline industry has been growing steadily since 2016 with more than 100 million air passengers, renewing the largest number of air passengers every year. Increasing air demand leads to an increase in air traffic in limited airspace, increasing the likelihood of accidents between aircraft. Due to the massive human and material damage caused by a single mistake, aviation safety is being heavily focused around the world to efficiently use limited airspace. Studies related to various human factors are underway as most of the aviation accidents are found to be caused by human factors, but research on human factors by controllers is insufficient while they are active in terms of control and operation. Given that 82% of air accidents caused by controllers are caused by human error, the importance of management of human error and changes in perception are urgently needed. This study aims to understand the seriousness of the controller's human error by analyzing the accident cases caused by the controller's human error using TEM to identify threats and errors and derive common human factors.

As human factors are the most important cause of construction accidents, it is important to reduce human error in construction work to reduce accidents. However, the error forcing context in organizational situations acts as a factor behind human error. Therefore, fatal construction accidents were analyzed using the m-SHEL model, which can identify the factors behind human errors. Through such analysis, it was found that there are differences in the detailed factors behind human errors according to the type of fatal accidents in construction, This study is meaningful in that it confirmed through accident cases that it is important to understand and respond to organizational situations in order to reduce human error in construction work.

In this study, an analysis was conducted on internal and external factors related to fires in electric vehicles in order to improve the safety of electric vehicles against fire accidents. To conduct the analysis, field survey data conducted on actual electric vehicle fire accidents were used, and accident-related statistical data was used. Among them, as a result of analyzing the internal factors related to fire accidents in electric vehicles, it was confirmed that high-voltage batteries are an important factor in fire accidents caused by internal factors of electric vehicles. An analysis of external factors for fire accidents of electric vehicles was also conducted in this study. The largest number of electric vehicle accidents that occurred on public roads were mainly caused by physical external forces such as collisions. Therefore, strengthening the safety of this road infrastructure could be an additional solution to improve the fire safety of electric vehicles. As a result, based on car accident cases, two crash scenarios based on road infrastructure were derived, each of which simulates a high-speed frontal collision situation and a lower-end collision situation. Additionally, detailed test methods for these scenarios were developed.

The first successful sustained powered flight by Wright Brothers was further extended to the rapid development of aviation technology, that led to transpacific flights, the invention of supersonic planes, and enabled hundreds of people to travel in the space, in addition to the fact that around 10 people had stepped on the moon, all of which were made possible within the very same century. However, on the back side of this most wondrous human technology, the vulnerableness to the aviation accident has been constantly accompanied with, right from the very beginning stage of the aircraft development. Moreover, the development of future aircraft is being focused on the aircraft performance, the increment of the number of passengers aboard and also its speed. In proportion to these phenomena of mega sizing the aircraft, the development of new technology and the increment of air traffic volume, the number of aviation accident is expected to augment, resulting in the enormous loss of human lives and properties. In order to prevent the disastrous aviation accident as such, it is essential to conduct the accident investigation in a specialized, systematic and scientific manner. In search for the method to attain the effective function of the aviation accident investigation organization, in this study, issues were examined as follows: The full-time Board Members and the establishment of an integrated investigation agency, The systematized security of status as an accident investigator, Inclusion of a human factors specialist in the investigator group organization, liability limit of an accident investigator Stipulation of the definition and the investigation scope of an accident and serious incident, along with the main body of conducting the investigation into the accident involving both civil and public aircraft, in the regulations related to the accident investigation.

The purpose of this study was to analyze the characteristics of socio-demographic, organizational conflict and job satisfaction, and to examine the interrelation of influential factors in the intention of turnover. The data for this study were collected through a self-administrated survey with a structured questionnaire to 1,027 subjects from several medical doctor staff members, nursing staff members, administration staff members, pharmacist, and technical expert of eleven hospitals. The data were collected by self-reporting questionnaire from July 29 to September 7, 2002. In this analysis frequency test, t-test, ANOVA, multiple regression were used. The main results of this research is as following; 1. According to socio-demographic characteristics of the respondent's level of the intention of turnover was higher in a doctor staff members than others, for females than males, and had worked for 5-10 years in hospitals. Also, the intent to turnover was generally higher younger workers than long terms workers. 2. According to the organizational conflict characteristics as the respondents who got less conflict experience in the organization, their level of the intention of turnover was higher. And, technical conflict experiences were expressed greater than hierarchical conflict experiences. 3. According to the job satisfaction characteristics as his or her satisfaction that is about the promotion, working itself, salary, and fellowship in the organizational was higher, the level of the intention of turnover was lower. 4. According to the result of Multiple Regression for the doctor staff members in general hospitals rather than special hospitals was negatively correlated with the satisfaction of working itself while hierarchical conflict factors in the organizational conflict characteristics was positively correlated with the intention of turnover. For the nursing staff members the job satisfaction for the working itself, salary were negatively correlated with the intention of turnover. For the administration staff members as the job satisfaction for the working itself was negatively correlated with the intention of turnover. For medical and pharmacy staff members as more working experience, correlation with the intention of turnover was negative. Besides, as the job satisfaction for the working itself and the fellowship was negatively correlated with the intention of turnover. For the skill and technicians, the job satisfaction for the working itself, promotion were negatively correlated with the intention of turnover. The above indicate that job satisfaction and promote their ability and form a good relationship with organization members were very important to decrease the intention of turnover. This study identified the major effective factors of the intention of turnover and analyzed the differences among the job category. In that respect, it is significant for the study to be able to provide a reference for managing hospital of industrial accident and organizational development. However, this study has a problem, which is not to identify a valuable model for examining the relationship between organizational factors such as organizational conflict, job satisfaction, and intention of turnover. Therefore, further study is needed and strengthened in the field of intention of turnover for hospital for industrial accident.
