When a fire breaks out in a distribution center, it causes a lot of damage. And the most casualties are caused by Fire accidents. Therefore, training for fire prevention should be mandatory at the distribution center. Also, the contents of education should be different in room temperature warehouses and low temperature warehouses. Fire education in low-temperature warehouses should be more emphasized. This is because many fires occur in low-temperature warehouses. In this study, a study was conducted to determine the important order of training hours and contents for fire prevention education according to the type of distribution center. The importance of time and content for safety education in all types of warehouses did not differ significantly. It was first decided that safety prevention training should be conducted periodically in all types of warehouses

With recent growth of population and industry, urban development grows into grand scheme of excavation and construction in urban area. As the development progress advanced, the developments get large and deepen. With a progress of technology development in geotechnical engineering in Korea, most our grand scheme of projects follows great progress. On the other hand, some excavation in construction site caused direct or indirect event that affects the adjacent or surrounding structures by excavation from time to time. This event usually happens around residential and commercial area where underground tunnel, subway station, commercial building, and high-rises excavation site is, could lead great damage on economy as well as personal injury or human casualties. In order to prevent this event, the study has to be done with analysis on various events of excavation and its cause. In this paper, the research has collected the various excavation events and their causes to analyze on each site and event to define emphasis on surrounding environment.

The collisions at sea among marine casualties are not reduced as the tonnage and speed of ship's increase as well as the traffic quantity increase at sea, in spite of the improvement of nautical equipment, enforcement of crew's education and training as well as improvement of quality standard according to the implementation of ISM code. The measures to prevent the collisions at sea are simple, and are composed of six stage.: The first stage is that the officer on duty detect the target from his eye or radar information. The second stage is determining the type and kind of target-ship. The third stage is target tracking; calculation of target speed, course, CPA and TCPA from radar information or visual check. The fourth stage is determination of vessel in danger after calculation of third stage. The fifth stage is the judgement of situation if own ship is stand-on or give way vessel according to the 1972 COLREG. The last stage is to carry out proper action according to 1972 COLREG, under the circumstances. But by the case, the situations are so different under the different external conditions; for example, natural/navigational conditions, crew's human factors, ship's particular, rule or regulation, management system on board, the condition of watch keeping. Therefore the reasons and casualties are so complicated. This study aims to investigate the collision casualty at sea which needs to clarity all these causal factors of afore-mentioned, and to analyze the causes of problems so as to utilize them to establish the measures of preventing marine accidents. This study, described the concepts of causal factors into three groups; environmental factor, and company/on board management system and navigator's act. Also described how to investigate and analyzes the casual factors. Even though it was described in this paper how to detect the causal factors and reasons of collisions, and how to analyze the inter-relation of each causal factors, it is necessary to do further study how to analyze between the liability of concerned parties and the casual factors involved.

Objective: The purpose of this study is to measure the workload of Korea coastal ship crew members, to investigate whether they are following work-break time regulations and to identify the main causes of their workload. Background: According to the US Coast Guard, about 33% of human casualties are reported to be due to fatigue, and 30% of marine casualties reported by the British Marine Accident Investigation Agency (MAIB) are attributed to crew fatigue. But the coastal ship are not managed for business hours and breaks despite the harsh environment. Method: The workload of duty crew members on the 100 domestic coastal vessels was measured. It was also investigated whether they are following domestic and international work-break time regulations. Finally, the marine accidents resulted from the fatigue of the crew was analyzed. Results: As a result of workload analysis, the workload on the 42~62% of the vessels exceeded the standard of working time on the related regulation. The workload increased with the number of inbound and outbound ports. Especially, in the system where there are two seafarers, the workload exceeded the working time requirement. As a result of the marine accidents analysis on 100 vessels, it was found that collision and grounding occurred due to fatigue, workload and drowsiness in 7 marine accidents out of 30 marine accidents. Conclusion: It is necessary for the shipping companies to introduce an operation management manual for the management of the crews' workload and reasonable crew arrangement. It is also required for crew members to easily record work times and for shipping companies to manage the record. It would be possible to prevent many marine accidents by providing adequate rest to the crews and flexibly adjusting their working hours. Application: The results of this study can be used as fundamental data to manage crews' fatigue and to make job management manuals.

Tsunami is a frightful natural disaster that causes severe damages worldwide. To minimize the damage, South Korea has built a tsunami warning system and designated evacuation sites in the east and south coasts. However, such countermeasures have not been verified whether they are adequate to minimize casualties since tsunami rarely occurs in South Korea. Recently, due to increasing earthquakes in the west coast of Japan, the likelihood of South Korea entering the damage area of tsunami rises; thus, in this paper, we develops a simulator based on Unity game engine to simulate the evacuation from tsunami. In order to increase the fidelity of the simulation results, the simulator applies a tsunami simulation model that analyzes coastal inundation based on cellular automata. In addition, the objects included in tsunami evacuation, such as humans, are modeled as an agent model that determines the situation and acts itself, based on the discrete-event system specification (DEVS), a mathematical formalism for describing a discrete event system. The tsunami simulation model and agent models are integrated and visualized in the simulator using Unity game engine. As an example of the use of this simulator, we verify the existing tsunami evacuation site in Gwangalli Beach in Busan and suggest the optimal alternative site minimizing casualties.

The purpose of Maritime Safety Tribunal is that experts about ship operation investigate and reveal causes of marine disasters and suggest plans to prevent recurrence in Korean Maritime Safety Tribunal which is a kind of administrative court. Despite the fact that 72% of marine disasters is fishing vessel accidents and 75% of collision accidents between vessels which most occur is related to fishing boats, it is the very serious problem that there is no any person with licenses of marine technicians for fishing vessels in judges and investigators of Korean Maritime Safety Tribunal. The operational characteristics of fishing vessels, their sizes, and shift patterns of duties in wheelhouses are completely and incommensurably different from those of merchant vessels. By the way, if the investigators and judges who just consist of merchant vessel experts investigate and judge marine accidents about fishing vessels, there could be errors in establishment of policies to investigate and reveal their causes and prevent recurrence of accidents. Especially, in case of collision accidents between fishing vessels and merchant vessels, it is thought that the marine accident interested provides causes which can be doubtful about fairness of judges. Therefore, it is thought that the ratio of judges and investigators is most desirable to compose it to be similar to the occurrence frequency of marine accidents. For this, the following solution plans are suggested. First, qualification for appointment requires first class marine technicians. But there is the only one vessel which needs the first class in fishing vessels. Therefore, it is thought that the provisory clause should be added so that the second class marine technicians can be used instead of the first class ones. Second, the marine accidents of fishing vessels reach 72% but the fact that there is no any judge and investigator with licenses of marine technicians for fishing vessels is thought to go against the purpose of establishment of Korean Maritime Safety Tribunal. Therefore, it is thought that there is, at least, one more judges and investigators in the central and local Korean Maritime Safety Tribunals. The same method should be applied to judge assistants and investigation assistants.

The differentiation of sex is important for species preservation. However, Fairy Pitta is sexually monomorphic and sex of an individual is indistinguishable with its external characteristics. We determined the sex of Fairy Pitta through DNA analysis and investigated the causes and time of injury and mortality and the size based on sex. We collected 21 samples at Jeju Island, Korean Peninsula from 2004 to 2013 and extracted DNA from them and amplified chromo helicase DNA-binding gene from Z and W chromosomes through Polymerase Chain Reaction (PCR). We confirmed their sex with the banding pattern through Agarose gel electrophoresis, i.e. male (ZZ): one banded and female (ZW) two banded. We distinguished the sex of 17 of 21 samples resulting in 9 males and 8 females. Most casualties were recorded in adult of both sexes. Causes of injury and mortality proved that female casualties occurred from window strikes, dehydration, car accident, predation by natural enemies, and male occurred from window strikes, car accident and dehydration. The time of injury and mortality in adults differ by sex. There was no difference between sexes in any of the six size parameters. As the time of injury and mortality differ by sex, the survey on the role and ecological nature by sex in breeding season must be carried out in the future. External measurements may not be reliable for sexing of Fairy Pitta and other traits such as vocal or characteristics are required to identify the sex of individuals in the field.

Objectives: We investigated the status of accidents and deaths caused by chemical leakage and skin contact in Korea. The purpose of this study was to produce and provide technical reference data for the efficient management of accidents and the rational management of accidental chemicals. Methods: Accidents and deaths caused by chemical leakage and skin contact in industry were investigated. Based on 68 accident reports related to chemical leakage and skin contact, the causes of accidental deaths were analyzed. In addition, we investigated the chemical substances and articles that caused these accidents and deaths. Based on the results of the investigation, the causes of accidents caused by chemical leakage and skin contact were identified and practical management measures for the chemicals were suggested. Results and Conclusions: In 2018, 372 people suffered from chemical leaks and skin contact, up by 123 (about 49.4%) from the previous year. The number of accident deaths was 14, an increase of five (about 55.6%) from the previous year. In the last three years (2016-2018), 91 chemical substances and article groups were involved in accidents caused by chemical leakage and skin contact. There were 16 chemical substance and article groups involved in accidental deaths. There were ten cases of accidents involving two or more casualties due to chemical leakage and skin contact, and 23 deaths occurred. Most of these accidental deaths were caused by subcontractor workers outsourcing risks. Therefore, there is an apparent need to strengthen the responsibility for safety and health among subcontractors.
