  • The using of Gun powders are getting grower than power due to the road opening, tunnel digging, the highest building, the pound digging on the construction industry, it also happen blasting accident as well, and it become society issue more than more. In this study, The check list far the human cause of the most rate among the blasting accident was developed in availing of accident investigation chart for the analysis of the blasting accident of already developed and FTA technique analysis with the analysis systematically of blasting accident. And then, Analysis for the application was carried out in construction cite, availing of the check list. As results, The most error has broken out at charge work, an uncomfortable processes, among the blasting work. Thus, It is a matter for consideration with improvement work.

  • Construction accidents are very serious comparing to its workers. These kind of accidents consist in the particularity of construction. The accident prevention task in construction requires both into immediate approach and longer range approach of instruction, training and education. Information concerning each individual accident, if the information of investigation has been done well, it provides information of prevention accident. At this point, this paper by examining 800 cases of serious accident researched by the Korea Occupational Safety and Health Agency from Jan. 1992 to Dec. 2000 specifically targeting apartment and building construction develops the construction information system to suggest the proper information of construction safety.

  • The estimation of occupant injury risk at crash accident is one of the most important assessments for the vehicle crashworthiness performance. The design of safety devices such as occupant restraining system also depend on the kinematics of occupant and its injury risk. The real world in-depth accident investigation provides detailed and realistic information of vehicle damage and occupant injury as well as the accident conditions. This paper introduces a statistical analysis of NASS/CDS database and domestic accident data to correlate speed change, vehicle damage extend, and occupant injury at frontal crash. The maximum crush extend shows a linear relationship with the effective impact speed. The injury risks of the occupant with and without restraining were also respectively quantified with the crush extend. This result can be effectively used for the emergent rescue of crash victims with automatic crash notification system.

  • Occupant behaviors and body contact with vehicle interior parts are main injury mechanism in far-side collisions. In vehicle side impact accident where the crash accident occurs on the opposite side of the vehicle from the a particular occupant, it is exposed in terms of relatively larger lateral motion to interact with the opposite side of the vehicle structure. The challenge of minimizing motions of upper body and injury risk according to a direct contact is a primary occupant protection research. This study has performed a data analysis of real-world accident database extracted from the 2016~2020 CISS database and a parametric investigation of impact angles and occupant kinematics in far-side lateral and oblique impact simulations. A detailed data analysis was conducted to reveal the relationship among the accident and injury data. Database analysis and computational far-side impact results proposed the fundamental vehicle design for safety improvement in far-side collisions.

  • Dextromethorphan (Romilar. DEX) is a synthetic analogue of codeine. is not classified as a narcotic and is used only for its antitussive effects in Korea. The daily intake by adults range up to 120mg. Usually in the case of traffic accident. alcohol concentration of blood is analyzed in Korea. but drug tests (medicine, narcotic. alcohol) are submitted in Australia. In crimes of violence (2 examples), a traffic and a murder accident. drug testing in urine and blood was performed. (omitted)

  • This study was conducted with respect to the causal factors revealed through the investigation of the recent airlines aircraft crash accident which occurred while aircraft was on the climb-out or on the final approach. This study also highlighted the importance of flight deviation and exceedance occurrences in consideration of Flight Operational Quality Assurance Program(FOQA). Twenty airline pilots participated in the flight experiment to perform ten(10) sets of simulated approaches and landings. As a result, Twelve(12) kinds of deviation events were discovered. In this respect, The FOQA program must be fully implemented to prevent any flight safety incident under the auspices of the Korea domestic aviation community as well.

  • The present study performed numerical investigation to analyze the smoke behavior in the rescue station by using the commercial CFD code (FLUENT Ver 6.3). The present study adopted a 10MW ultrafast mode for simulation, and it also used the MVHS(Modify Volumetric Heat Source) model modified from the original VHS(Volumetric Heat Source) model in order to treat the product generation and the oxygen consumption under the stoichiometric state. In addition, the present simulation includes the species conservation equation for the materialization of heat source and the estimation of smoke movement. From the results, the smoke flows are moving along the ceiling because of thermal buoyancy force and as time goes, the smoke gradually moves downward at the vicinity of the entrance. Moreover, without using ventilation, it is found that the smoke flows no longer spread across the cross-passages because the pressure in the non-accident tunnel is higher than that in the accident tunnel.

  • In a previous study, an investigation of occupant behaviors and injuries (to the head and chest) was performed during vehicle impact loading cases in order to ensure the safety of wheelchair passengers on a bus. The computational results showed overall safety tolerances of wheelchair occupants under different accident configurations. The bus crashworthiness is described as the capability of a bus to protect occupants during rollover loadings. The residual space containing occupants should be undamaged without any intrusions. However it is necessary to evaluate the residual space according to the bus occupant kinematic analysis under the rollover crash simulation. This study focuses on the evaluation of occupant behaviors during rollover loading cases in order to ensure the safety of bus passengers sitting in general seats and wheelchairs and evaluates the residual space of the bus by analyzing the bus occupant kinematics.
