In an effort to enhance the independence of and expertise in military aircraft accident investigation, a permanent accident investigation board should be established. Establishing permanent accident investigation board would render the military accident investigation more reliable and would increase its public esteem. Because there is no provision governing the responsibilities of the investigation and cooperation between civil and military authority in case that both civil and military aircraft are involved, it is necessary to fill this gap by enacting appropriate laws. In case of civil aircraft accident investigation involving a military issue, it would be better to allow military authority to be involved in the investigation. For the betterment of investigation, it is also necessary to provide a field investigator an authority to directly collect relevant information. Since the sole purpose of accident investigation is to prevent the recurrence of aircraft accidents, the scope of information disclosure should be limited and the investigation report shall be used for neither criminal procedure nor disciplinary procedure so that the objectivity of the investigation should be ensured.

This study deals with the pedestrian accidents of intersections in case of Cheongju. The objective is to develop the pedestrian accident models using Tobit regression model. In pursuing the above, the pedestrian accident data from 2007 to 2011 were collected from TAAS data set of Road Traffic Authority. To analyze the accident, Poisson, negative binomial and Tobit regression models were utilized in this study. The dependent variable were the number of accident by intersection. Independent variables are traffic volume, intersection geometric structure and the transportation facility. The main results were as follows. First, Tobit model was judged to be more appropriate model than other models. Also, these models were analyzed to be statistically significant. Second, such the main variables related to accidents as traffic volume, pedestrian volume, number of traffic island, crossing length and the pedestrian countdown signal systems were adopted in the above model.

It has been only a few years since drones have been introduced to Korea, and as the use of drones has increased in industrial sites as well as in hobby activities, accidents such as workers' body parts coming into contact with rotating propellers have been occurring since 2016. Industrial accident cases are being filed. In the case of a remote control vehicle, if you release the remote controller in the event of an abnormal situation, it stops in place and no further danger occurs but in case of drones flying over the sky is different. Sudden motor stops during flight, uncontrolled changes in flight posture, loss of radio waves, loose propeller, etc, numerous factors can lead to accidents due to unintentional movements. Therefore, drone operators need safety knowledge as well as high knowledge about drones. However, drones with a weight of less than 12 kg can fly without a pilot's certification, and therefore, a minimum accident prevention measure is required. 10 accidents approved as industrial accidents since 2016, 23 accidents surveyed by general drone operator, 40 accidents surveyed by the Korean Consumer Resources Unfortunately for the purpose of writing this paper, drones are a new species and do not have many parameters for analysis but my experience has shown that the type of disaster does not deviate significantly. In addition, there is no paper that analyzes drone related industrial accidents not only in Korea but also in other countries. However, even if you watch an overseas drone accident video through YouTube, it is not much different from the case that occurs in Korea. I hope that this study will be of little help to all the drone pilots as well as the work safety of industrial drones used in industrial sites.

This report describes the efficacy of using Yangshimtang-gamibang for a sleep disorder caused by a traffic accident. We treated a patient with Yangshimtang-gamibang for 12 days for sleep disorder caused by a traffic accident. To evaluate the results, we used the Korean Modified Leeds Sleep Evaluation Questionnaire (KMLSEQ) to measure sleep disorder. The degree of sleep disorder was also evaluated using the Numerical Rating Scale (NRS). The generic health status was evaluated using the European Quality of Life-5 Dimensions (EQ-5D) scale. Improvements in the NRS and EQ-5D scale scores were observed after the treatments. The change in the KMLSEQ score indicates that the patient's sleep disorder was relieved. The results of this case study suggest that Yangshimtang-gamibang may be an effective treatment for sleep disorders caused by traffic accident.

Purpose: In South Korea, two kinds of mandatory insurance, Fierce Liability Insurance and Outdoor Advertising Liability Insurance sells as of February 2021 according to relevant codes. This study analyzed third party liability and personal living liability insurance in terms of various risks not corporation side but personal side arising from normal living and life. Research design, data and methodology: Some cases of drone accident hit man and fierce dog accident were taken into analysis to verify blame ratio and insurance claim money. The former case is that on the way down the elevator, the dog, American pit bull terrier rushed in and bit the lower part of the knee against the visitor. The latter case is that while flying in the sky as usual, the drone suddenly crashed, fell, and hit the head of a young child while walking on the street. Further previous studies such as third party liabilities, liability insurance, mandatory insurance were deeply analyzed. Results: Based on some case studies and previous studies, the author suggested valuable comments in turn realization of insurer as provider, exhaustive creation and operation of mandatory insurance, realization of insured as demanded, and arrangements of laws and systems in special consideration of amendment of companion animal and exhaustive execution of mandatory insurance by the government. Conclusions: This study was about third party liability, personal living liability insurance and expansion of mandatory insurance caused by relevant laws by the government. In this study the author verified what issues were observed from two cases drone accident and fierce dog accident and then suggested some valuable comment as above both systemic plans and practical plans. First of all, the individual should get Comprehensive Property Insurance(CPI) that covers the risks of his/her own property arising from the everyday life. And then the individual should further buy Personal Living Liability Insurance(PLLI) in order to prepare 'accidents that may happen when, where, or how' and overcome the said accidents. Moreover, the individual should take a look every single insurance contract whether he/she has a special terms and conditions of Personal Living Liability Insurance(PLLI) or not.

The generic analysis method for core flow instability is suggested to confirm that the core flow instability would not occur on PWR conditions. For the confirmation, the stability criteria of each fuel type are provided. Instability investigations in various accident conditions prove that the locked rotor accident is the most limiting case to instability. Parametric Effects are surveyed and in good agreement with available studies. The effects of heat flux distribution become negligible as the subcooling number is decreased. The power margin to instability is calculated quantitatively in various accident conditions.

In this paper, we propose the application of the Human Factors Analysis and Classification System(HFACS) to analyze an aircraft accident data. HFACS is a general human error framework originally developed and tested within the U.S military as a tool for investigating and analyzing the human causes of aviation accidents. It was examined that HFACS reliably accommodate all human causal factors associated with the commercial accidents. We found that the HFACS could be used as a reliable tool for investigating aircraft accidents including a single accident analysis.

Fire accident in tunnel is one of the most critical railway accidents, together with overturning of train by derailment and train crash. Tunnel structures contribute to minimize the cost and time of transport, but in case of railway fire accident occurring bring serious damages of human life caused by narrowness of shelter, poisonous smoke and high temperature raised at the inside of tunnel. For that reason, at the beginning of plan of tunnel, the optimum design for rescue of passengers is needed. For the detail and most suitable design for rescue of passengers, many tunnel designer substituted simulation program for mock examination by its high cost and effort. In this study, simulation program techniques, such as Fluent and Simulex, are applied for verifying the rescue design of passengers reduced the risk when fire accident occurred at tunnel utilizing of case study for planned railway tunnels shows 1,245m length in Iksan-Sili area.
