철도기술 현장에서는 국가기술검정자격 이외에 철도종사자들에게 열차운행안전과 직접 관련이 있는 모든 기술분야에서 차량을 제외하고는 전문자격을 도입시행하고 있다. 철도차량은 승객이 직접 이용하는 것으로 안전과 가장 가까움에도 불구하고 자격이 없이 정비에 임하고 있는 것은 안타까운 일이다. 항공기나 자동차, 선박 등은 자격자가 정비를 하거나 정비상태를 확인하는 자격제도를 시행하고 있다. 이 논문에서는 철도차량의 종류, 보유량, 종사자, 운행상태, 정비업무 등을 파악하여 철도차량정비의 자격제도를 도입하는 방안을 살펴보고자 한다. Above national technical qualification examination, professional qualification for railway workers is introduced and operated in every technology field relevant to train running safety except for vehicle. The approximate repair without qualification is very dangerous because railroad vehicle is directly related to safety of passengers. In case of aircraft, cars, ships, etc., workers who have qualification repair their vehicles and check the status of the maintenance. In this paper, it introduces ways of qualification system introduction in field of railway vehicles maintenance through analyzing kinds of railroad cars, stocks, workers, driving conditions, maintenance work.

The Challenges facing women the issue of sexual harassment in the workplace. Many people spend much of their working lives in organizations thinking about sex or romantic relationships, but very little attention has been paid organizational sexual harassment In recent years, an increasing amount of employment-related litigation has centered on sexual harassment Sexual harassment define the term "unwelcome sexual advances, requests for sexual favor and other verbal or physical conduct of a sexual nature." The guideline are written in such a manner as to make clear beyond reasonable doubt that protection against sexual harassment extends to both male and female employees. In general, the employer can limits its liability by showing that it took immediate corrective action when the sexual misconduct was discovered The following constituted sexual harassment: I can't seem to go in and out of my boss's office without being patted or pinched: my boss told me that it would be good for my career if we went out together. In one incident, a male supervision had a habit of making jokes with sexual overtones to a female subordinate who appeared to take no offense and made complaints. This case study explored about sexual behavior at work, including personal sexual orientation, sexualization of the at work, and workers in male or female dominated jobs, co-worker or supervisor's sexual behavior and attitudes toward sexual harassment. We found that women in personal sexuality oriented, sexualization of workplace, and job position were more likely than other women to label as sexual harassment The result of this have a number of implications for the field of organizational behavior and for managers concerned with sexual harassment in their organizations.

The important factor to evaluate the running safety of a railway vehicle would be the interaction force between wheel and rail(derailment coefficient), for which is one of important factors to check the running safety of a railway vehicle that may cause a tragic accident. Especially, a newly developed vehicle that first runs commercially requires necessarily the measurement and evaluation of derailment coefficient for securing the safety of a vehicle while measuring the derailment coefficient in view of securing running safety could be the more important factor than any other factors. In this paper, examined possibility that can forecast derailment possibility to behavior of only vibration and displacement by measuring vibration acceleration and displacement in vehicles that travel actuality rail track, and compares with data of wheel load/lateral force result.

장래, 철도기술개발은 열차의 탈선, 충돌 및 화재 등으로 일어나는 철도삭를 예방하기 위한 안전에 관한 기술과제, 편리성 향상에 관한 기술과제(기존선 고속화 , 고속 철도망 구축, 저 진동 철도개발, 연계수송, 저비용 유지보수), 도시철도에 관한 기술과제(유지보수성, 도시철도 혼잡완화, 시간제약 철폐, 거점역간 연계), 철도를 이용한 물류에 관한 기술과제(고밀도/소량수송, 연계수송, 고속 화물 수송, 지능철도기술개발) 등의 개발이 이루어질 것으로 기대된다. Future, developemtn of railway system is expected to be made technological development such as technical project on the railway accident(derailment, collision, fire, etc.) prevention, technical project on the improve convenience(the speed-up of conventional railway lines, high-speed rail network, low vibration railway, transportation connection, low cost maintenance), technical project on the urban railway(maintainability, congestion alleviation, time constraints elimination, intro-base connection), technical project on the railroad logistics(higher volume/small quantity transport, transportation connection, high-speed freight transportation, intelligent railway technical development).

When the electric motor car was first introduced, an engineer, responsible for the work related to operation and a conductor for the announcement and management of entrances and the other services like as monitoring the passengers in the platforms used to take together the train for passengers" safe. As new technologies developed and the urban transit system had the automatic driving facilities, automatic door switch and broadcasting systems, to solve the financial problems, most subway systems introduced the one-man operation system. To curtail the operating expense through automatic control and operation for the economical efficiency, the crewless driving system was introduced abroad around 1970 on the light weight train and Japan started the crewless driving system in 2005, Germany started it in June 2008. We examine system requirements of the system and methods to construct safe systems that would be introduced, suitable for one-man operation system or crewless driving system through the surveys and analysis of driving state and the systems.
