The Seoul Subway is one of the most heavily used Subway System in the world. It provides reliable transportation services, conveys nearly 4 million Passengers across 117 subway stations with a length of 134.9 Km. Over the years the safety for the Subway has been a major concern, trains going off the track, equipment failure, careless operation, Signal failure are increasing day by day. In a Recent Public opinion 40% said the causes to above facts are Vehicle breakdown because of Operators, Old rail defect, Quality of material. 20% of the opinion said the obstacles were because of Operation, crew carelessness, negligence in signal operation. In case of any accident the crew members cannot resolve the issue on site (Aid insufficiency), because of lack of knowledge and carelessness. The main obstacles for Subway are vehicle breakdown, Electric equipment failure, Signal Equipment failure, and Crew carelessness. This paper aims to provide major problems which are needed to be solved as quickly as possible for citizen's safety for a comfortable subway system making a comfortable ride and providing better service gradually.

Many electrical socket-outlet fire accidents take place not only in homes but in the offices each year. The causes are mostly faulty constructions, managerial problems and carelessness. Construction and managerial flaws can be resolved by regular or special inspections, but carelessness is not solvable through inspections. Such carelessness can be related to the consumption capacity of electrical socket-outlets presently, the rated current of electrical socket-outlets is based on 16A. However, even at 16A, the heat generated in the insulator of an electrical socket-outlet varies due to such factors as part damage and environmental conditions of use. To explore this situation, the study conducted an experiment to analyze thermal relationship by applying 10A, 20A, and 30A currents. To secure reliability, the study employed thermal analysis simulation and compared the thermal relationship in the same current value. The experimental and simulation values were found to be similar and therefore, diverse current values were replaced with the simulation. At 30A, the temperature was found to rise to at least $169.9^{\circ}C$ which had worked as a sufficient amount of energy to bring the insulation aging of insulator.

A study on the fire scenario proposal of residential facilities by using fire statistics. as a result of analyzing residential facilities fires by using fire statistics of national emergency management agency during 2007~2012, fires from carelessness were the most causes. specially, fires during food cooking among carelessness showed the highest occurrence frequency, and followed sparks, neglecting fire sources, and cigarette stubs in order. through this the study suggested fire scenarios according, It is believed that can be used as basic data for applying a secure building in a fire using a basis for fire safety design of buildings in the future this.

각종 화재사고 분류 중 대표적으로 나타나는 가스사고는 그 형태와 원인이 다양하다고 할 수 있다. 가스사용량은 사용가구수가 증가와 사용 장소 및 가스기기의 다양화로 증가하고 있으며, 2007년도 가스사용량은 35,078천톤으로서 연평균 9.4%증가하였다. 가스사고는 95년 557건을 최고로 하여 2007년도에는 123건 발생하여 연평균 11.5%감소되었다. 가스의 종류에 따른 사고건수는 LP가스의 경우 전체 가스사고중 약 80%를 차지하고, 도시가스와 고압가스가 약 20%를 차지하고 있다. LP가 많았고, 특히 공급자부주의에 의한 사고가 끊이지 않고 증가하고 있는 추세이다. 가스사고는 사용자취급부주의, 공급자 취급부주의, 시공불량 및 노후제품으로부터 사고가 발생하여 인명과 재산피해가 발생하고 있다. 본 논문에서는 가스사고의 분류와 형태별, 원인별, 지역별 등에 대한 사고분포를 통해 가스사고의 원인에 대한 이해를 하고 가스안전사고를 예방하는 자료로 활용되도록 하였다.

The purpose of this survey was to investigate the exercise injuries and its care methods of members in amateur tennis clubs. 176 questionnaires were surveyed from tennis players who were exercising at 6 tennis club ranges in J city, Korea. The interesting variables were parts, time slots, causes, treatments of injuries, which were analyzed based on the general and exercise characteristics of surveyees, a gender, an age, an exercise career, an exercise time, an occupation, an average earning. The results of this study were as follows: 1) In the results of analyses for the injury parts, the upper bodies injuries were more than lower body ones, the injury of back and lumbus had the highest rate among upper body injuries. In twenties, the number of injury had highest rate. 2) The main cause of injury was the carelessness of one's own. The most injury by the carelessness of one's own was a reason for a lack of warm-up. 3) The first emergency manager for the injury was mostly oneself.

Purpose: The purpose of this study was to identify prevalence and risk factors of needlestick injuries (NSI) among nursing students. Methods: Data were collected using self-administered questionnaires which included general and practical characteristics, safe environment risk factors, knowledge, attitude, and preventive behavior associated with NSI. Data were conducted from December 14-20, 2014 and analyzed using $x^2$ test and multiple logistic regression. Results: The incidence rate of NSI was 20.2%. Multiple logistic regression analysis identified four predictors for NSI which were statistically significan; carelessness (OR=1.49, 95% CI=1.04~2.11), status of hospital, university affiliated (OR=1.93, 95% CI=1.35~2.75), knowledge about handing the needle after NSI (OR=1.42, 95% CI=1.00~2.03), and barriers to NSI preventive behavior (OR=1.48, 95% CI=1.04~2.12). Conclusion: Management of carelessness and barriers to NSI preventive behavior are essential elements for reducing the risk of NSI in nursing students. It is necessary to develop a specific NSI precaution program for nursing students.

Forest fires in Korea usually start in the fall and occur every year until spring. Most wildfires are human resources that combine topographical characteristics and carelessness, and failure to respond in the initial stage and lack of cleanup are spreading to large-scale wildfires. In order to prevent these wildfires, active cooperation from the public is essential. As can be seen from recent wildfires, the attention of the public is needed above all else because large-scale wildfires in Korea are occurring due to the people's negligence. If a wildfire spreads and becomes large, it causes damage to life and property, and the damage is irreversible. In this study, various methods were used to prevent forest fires and improve initial suppression ability. In order to minimize damage, the model analyzed by the 119 Special Rescue Team in Gangwon, Chungcheong and nearby forest fires was analyzed on the combustion progress and wind direction by time period. The propagation speed by the wind direction was simulated. Until now, most of the wildfires have been extinguished by firefighting, but I hope that the Forest Service will take the lead and maintain coordination with related organizations.

Recently, in Korea, if a very large forest fire occurs due to the people's carelessness, it is of great interest because it spreads into a large forest fire. If a wildfire spreads and becomes large, it will inflict great damage (appointment and property), and the damage is irreversible. The best way to extinguish a wildfire is to prevent it before it occurs. If a forest fire occurs due to a failure in prevention, the early firefighting activities to prevent the progress of the forest fire by promptly dispatching it by reporting it and approaching the site as soon as possible should now be managed with a systematic integrated management system. To do so, it is necessary to prepare a preventive system, such as issuing warnings for each weather condition by the Korea Forest Service, consisting of cooperation (support) activities for forest fire prevention by related organizations, etc. In order to minimize the loss of precious lives and forests, measures have been taken to establish a system, to establish a prompt and accurate situation reporting system, and to establish an integrated command system (ICS) for on-site commanders.
