This study examined the effect of railway traffic controllers' negative perception of organizational culture on their job demand and job satisfaction in relation to the moderating effect of self-efficacy. Results showed that the aggressive/defensive culture based on power and competition, had a positive (+) effect on job demand and job satisfaction. On the other hand, in the conditional process model in which self-efficacy affects the relationship between organizational culture, job demand, and job satisfaction, self-efficacy played a significant role in lowering the level of job demand, and it contributed to the increase of job satisfaction through a mediating effect. This results suggest the needs for lowering the level of job demand by changing the present aggressive/defensive organizational culture into the constructive one. And also, much consideration for maintaining the level of their self-efficacy should be spent.

The safety culture of an organization is the product of individual and group values, attitudes, perceptions, competencies, and patterns of behaviour that determine the commitment to, and the style and proficiency of, an organization's health and safety management. A good safety culture includes effective, appropriate safety management systems; strong safety leadership & commitment from management; participation and involvement of the workforce; and organizational learning and continuous improvement. This paper will introduce the safety culture inspection standards and process in Korea Railway. The main purpose is to get a better understanding of safety culture and to develop measuring tool. First of all we developed the composition factor of safety culture and the question set. And we prepared the base of computerization of safety culture measurement by developing of evaluation standards and weighted value.

This study tried to figure out the framework of safety culture in railway industry to analyze root causes of railway incidents and accidents at Korean National Railway. Through the literature survey, authors found some critical dimensions common to railway safety culture such as employees' belief in the managers' management weight on safety and productivity, recognition of safety importance, risk taking attitude, practice of safety meeting before and after doing work, communication between management and employees and among drivers, traffic managers and infrastructure maintenance workers, safety reporting practice, safety and performance appraisal, effectiveness of safety audit, safety training, work place arrangement, incidents and accidents investigation, and safety knowledge management.

국내에서는 철도차량의 화재안전성능을 향상시키기 위해 성능평가를 적용하기 위한 연구가 진행되고 있다. 철도차량에서의 화재 시 피난은 여러 가지 시나리오들이 존재하며, 이중 하나가 터널내부에서 정전이 되어 무조명상태가 되는 것이다. 철도차량은 물리적 공간적 환경이 건축물과 차이가 있다. 또한 문화적 인종적 차이로 인해 외국의 데이터를 바로 적용하는 것도 바람직한 일은 아니다. 그러므로 시나리오를 분석하기 위해 필요한 데이터는 실험을 통해 확보해야할 필요성이 있는 것이다. 무조명 상태에서의 피난인의 행태와 이동속도의 차이 등을 분석하기 위해 실험을 수행하고 그 결과를 분석해 보았다.

In this study, we proposed the sacrificial anode cathodic protection method as a countermeasure to reduce the corrosion of railway rails under oceanic climatic conditions and proved the anticorrosive effect experimentally. In addition, the proposed sacrificial anode cathodic protection method were tested on site to examine long-term rail corrosion monitoring and field applicability for more than 26 months and to prove the effectiveness of rail corrosion. As a result of monitoring the corrosion state using the cellophane tape method, the appearance of the applied sections with sacrificial anode cathodic protection method was good at the present time about 26 months after the field test laying, and no abnormalities and other abnormalities of the rail welded section and the rail web were found. Hence, in places where no sacrificial anodes were installed, rust progressed rapidly. In addition, the proper spacing of sacrificial anodes was found to form the most stable corrosion coating at 1.0 ~ 1.5m. After about 26 months of monitoring, the installation of sacrificial anodes could help stabilize the overall rail corrosion level, even if the spacing was somewhat wider.

It is important to safety culture in railway industry because they variously refer to the safety-related values, attitudes, beliefs, risk perceptions and behaviours of railway employees. So this study tried to figure out the assessment criteria for safety culture at Korean National Railway. For the achieve the goal, we have the literature review, some assessment criteria have been founded by intensively comparing safety culture questionnaires in other industries to establish domestic railway safety. This study expects Korean railways to become a well-organized that as assessing safety culture with reasonable criteria or requirements.

Recently, due to adjacent excavation work such as new buildings and common tunnel expansion concentrated around the urban railway, deformation of the underground box and tunnel structure of the urban railway built underground has occurred, and as a result, repair and reinforcement work is frequently carried. In addition, the subway is responsible for large-scale transportation, so ensuring the safety and drivability of underground structures is very important. Accordingly, an automated measurement system is being introduced to manage the safety of underground box structures. However, there is no analysis of structural damage vulnerabilities caused by subsidence or uplift of underground box structures. In this study, we aim to analyze damage vulnerabilities for safety monitoring of underground box structures. In addition, we intend to analyze major core monitoring locations by modeling underground box structures through numerical analysis. Therefore, we would like to suggest sensor installation locations and damage vulnerable areas for safety monitoring of underground box structures in the future.

This study highlights the theme of human error of train drivers, conducting empirical analysis on the relationship between organizational culture, safety climates, safety behavior, and accident. The empirical test results based on questionnaires received from 223 train drivers working at A subway firm indicated that relationship conflict and psychological reward as the elements of organizational culture variables showed a significant positive effect on CEO philosophy, communication, and boss's leadership. And only boss's leadership showed a positive influence on safety behavior, which in turn showed a significant negative relationship with accidents.
