The purpose of this study is to investigate service factors and relationships affecting customer satisfaction by measuring indexes of the entire set of high-speed railway station facilities and train services. In this study, we collected data from 202 KTX passengers and analyzed the data using the structural equation model (SEM) method. Through exploratory factor analysis (EFA), we found five major service factors, including parking related service (PRS), station convenient facilities related service (SCS), ticketing services (TIS), service within the train (SWT), and inner environments (INE). As result of a hypothesis test, it was found that PRS does not influence SWT, whereas SCS and TIS positively affect train related service. Also, SWT and INE significantly affect the overall service satisfaction of customers. Thus, our findings provide that station facilities and train service experience are important factors that can enhance customer satisfaction.

The purpose of this study was to develop the curriculum for the Department of Food Service Business in Junior College. The purpose of the curriculum development is to train professionals combined theory and practice for medium or small restaurant managers. We have developed a model curriculum, which was based on Job analyses for related business, analyses of the curricula of departments related with food service, and survey on the questionnaire. The subjects of the model curriculum are as follows. 1) Subjects related with Food and Food Sanitation, 2) Subjects related nth Cuisine, 3) Subjects related with Restaurant Management and Service, 4) Subjects related nth training In practical business, and 5) Subjects related with a foreign language. The effects on opening the Department of Food Service are as follows. 1) To train professionals (or food service business, 2) Activation of the study on Food Service Industry, 3) Establishment of the traditional food culture, 4) Activation of the Tourist Industry, and 5) To improve the Quality of restaurant employees.

Tilting train is the best solution to provide faster passenger service on conventional railway lines without too costly modification of infrastructure. Kinematic envelope gauging is very important when applying tilting trains % conventional railways with limited clearance. Due to tilting motion, the kinematic envelope of tilting train is larger than that of non-tilting train. This study was done to estimate the maximum dimension of tilting train being suitable for Korean conventional lines. In this study the two worst cases of tilting train movement was assumed and related suspension displacements, geometrical overthrow of train on une, wear of wheel ＆ rail were combined to determine kinematic envelope.

As tilting train is the effective solution to provide faster passenger service on conventional railway lines without too costly modification of infrastructure, it is expected that tilting train will be put into service for Korean conventional Railway Lines. Very few passengers may suffer from motion sickness on conventional train and high speed train. But some sickness among passengers of tilting trains have been reported. Up to now, a standardized motion sickness index was mainly developed in the shipping domain. Therefore, there was a need for railway motion sickness index in order to predict and evaluate the motion sickness which is likely to be experienced by passengers. This paper is the preliminary investigation to propose the technical index related to motion sickness and nausea phenomena for the tilting train development and operation.

It is widely recognized that train Is one of the most efficient and convenient ways for passenger and freight transportation. However, the environmental noise problem is occurred with the construction and service of train. The noise problems caused by train prevent people from living in a silent environment. Furthermore, this problem is related with the right to preserve one's environment. The objectives of this research are train noise measurement and analysis which might be a base-study for prediction of train noise. This paper mainly deals with the noise of the 'Semaul' train. The train noise shows distinct characteristics according to the variation of height and distance. Furthermore, the database and its interface program are developed for systematic analysis and future research.

Assuming that life of urban transit signalling is about 20 years with the flow of technology development, Seoul urban transit will be required to prepare for improvement soon. The highly developed countries preceding several levels rather than Korea are faced with commercial service which uses RF, ATC and ATO in Train Control System. European highly developed countries in the field of railroad have been progressing standardization and technology development of signalling associated with related manufacturers for direct operation between nations. For that, a effective train control system with radio beyond control levels by the existing wayside-onboard communication is in a developed and used stage. The systems which advanced countries have been progressing seem to be applied to domestic within 5 years from now. At present, there are no countries using CBTC for service throughout the world. So, this is investigated to focus on the routes ready to be installed with completed CBTC and trying to introduce the technology. Especially, considerations for economic aspect are mainly reviewed about controlling ability of headway, flexibility, extension aspect and construction cost on the basis of paper examined in NYCT.

This paper explains development status of the Korean tilting train. The Korean Tilting Train eXpress (TTX) project has been carried out to develop all the core technologies related to tilting train and infra-technology to provide high speed inter-city service with the speed of 180 km/h as well as maintenance-free technology for conventional railway system. The TTX project is under 5th stage. In this stage, manufacturing and combination test for the main components are being conducted. By the end of next year, assembly of TTX will be completed.

Tilting trains are now an established feature of railway operations throughout the world. For intercity traffic, tilt provides operators with increasing speeds, and therefore enhanced competitiveness, on existing routes where insufficient traffic or a lack of funds precludes the construction of a dedicated new high-speed railway. This paper explains the reduction effects of journey time with the Korean tilting train. The Korean Tilting Train express (TTX) project has been carried out to develop alt the core technologies related to tilting train and infra-technology to provide high speed inter-city service with the speed of 180 km/h as well as maintenance-free technology for conventional railway system. In order to simulate we considered 5 conventional railway. As a results of simulation, we found out the tilting train has very high efficiency(reduction rate 20-30%).
