The purchasing behavior of consumers is related to service quality and corporate social responsibility (CSR). Therefore, CSR is recognized as an important factor in company strategies. This study determines the relationship between the CSR activities of KORAIL and the reuse intention and recommendation intention of the consumer. CSR is composed of economic, legal, philanthropic, ethical, and environmental responsibilities. In the results of the structural equation modeling analyses, legal responsibility and economic reliability affect the reliability of KORAIL and this reliability affects the customers' reliability and loyalty. This paper proposes a compliance program, wagon safety information, customized tour packages, and communication strategy that will increase customer's reliability and loyalty.

우리 나라의 또아리 굴은 중앙선 금교~치악간 R=400m연장 1,975m가 일제시대 건설 운행되고 있었지만. 금번 함백 또아리 굴은 순수한 우리기술을 투입하여 현 운행선인 함백~조동간 35$\textperthousand$의 병목현상구간을 해소하기 위하여 함백~조동 간에 24$\textperthousand$ 연장 2.450m R=400의 또아리 굴을 시공하게 되었으며 '74년도에 착공이후 공사부진으로, 22일간의 연체료를 물고 있는 현장이었으며 전임공사조역이 개인사정으로 퇴직하고 후임으로 '75년 6월 2일 태백공사사무소 태백선 함백~조동간 2공구 공사조역 명을 받음으로 인연을 맺게 되었다.

지난해 6.15 남북공동선언을 계기로 남북간의 교류와 협력의 분위기가 조성되고 남북정상회담의 가시적 성과의 하나로 이산가족상봉과 남북철도 연결사업이 시작되어 경의선의 남쪽구간은 상당한 공사진척도를 보이고 있다. 그러나 최근의 상황은 북쪽은 아직 공사조차 시작하지 않고 있는 입장이다. 그러나 이와는 별도로 남북철도의 연결과 이의 대륙철도와의 연결은 '철의 실크로드' 구성과 함께 시베리아횡단철도(TSR)의 이용이 그간의 논의 수준을 넘어 구체화 되었다. 게다가 수교이후 러시아가 가장 적극적으로 접근하고 있는 시베리아횡단철도(TSR)의 활성화 논의는 남북관계가 한러관계 나아가 남·북·러 삼각협력의 복잡한 구도 속에서 논의되고 있는 현실이다.

This study analyzed the relationship between major parameters and numerical analysis results according to various excavations conducted around the urban railway, application of machine learning techniques and verified the scope of influence of the adjacent excavation on the existing urban railway box structure and the appropriateness of the safety area. This study targeted the actual negotiated adjacent excavation works and box structures around the urban railway, and the analysis was conducted on the most representative two-line box structures. The analysis confirmed that the difference in depth of urban railway, excavation depth of adjacent excavation, and depth of underground water level are important parameters, and the difference in excavation depth of adjacent excavation is the parameter that affects the behavior of underground box structures and is an important requirement for setting safety areas. In particular, the deeper the depth of the adjacent excavation work, the greater the effect on the deflection of the underground box structure, and the horizontal separation distance, one of the important requirements for determining the management grade of the existing adjacent excavation work, is relatively small.

Recently, despite a decrease in the number of working days and an increase in the number of non-working days due to an increase in the abnormal climate and the revision of the Labor Standards Act, a standard construction period reflecting this has not been established. For this reason, even if the appropriate construction period is calculated at the site, there is a situation where delays occur due to unexpected circumstances. Therefore, this study proposes a method of calculating the number of non-working days for railway bridgework construction that reflects changes in construction conditions and climate change and reflects this to railway bridgework construction, and the number of working days was calculated. As a result, the number of non-working days by region and month in Korea was derived, and through this, the necessity of regulations and standards for appropriate construction periods reflecting regional characteristics and characteristics of each construction type was presented.

In this study, we tried to derive the most severe scenario and its critical speed by 1-D collision simulation with a variable formation vehicle in order to prepare for the change of demand in Seoul Metropolitan Subway Line 3, which is operated by fixed arrangement. After establishing various collision scenario conditions, the friction coefficient between the wheel and the rail was evaluated as 0.3, which is considered to be severe. As a result of analysis according to all scenarios, the most severe scenario conditions were confirmed by comparing rubber shock absorber performance and vehicle collision deceleration. In addition, a typical wheel-rail friction coefficient was derived through accident cases, and the analysis was performed again and compared. Finally, the criterion of the critical speed in the condition of the friction coefficient of the normal wheel - rail condition was confirmed.
