The dynamic responses of a PSC bridge for automated guide-way transit system are investigated by analytical approach of bridge-vehicle interaction. In this study, the dynamic responses, concerned with a spall on the surface of bridge are emphasized. A simply supported pre-stressed concrete bridge is adopted as a numerical example. Dynamics of three-dimensional dynamic interaction system between bridges and vehicles is considered in this study. The FE method and modal analysis is used for modeling a bridge for dynamic response analysis. An AGT vehicle is idealized as a model with 11DOFs including lateral motion. It was found that the dynamic responses of bridge can be affected by a spall of surface. Especially, the vibrations are increased much more when a spall is exist.

The objective of this study was to identify the relationship between exercise needs and exercise self-schema of students participating in university physical activity classes. The participants consisted of 243 students of A university located in Gangwon-do, who were participating in university physical activity classes. The collected data was statistically processed using SPSS 18.0 and AMOS 20.0. In order to verify the reliability of the survey questionnaires, Cronbach’s α value was calculated, and confirmatory factor analysis and exploratory factor analysis were performed for the validity of the survey questionnaires. To obtain information of personality traits, frequency analysis was implemented. The average and standard deviation of measurement variables were calculated and correlation analysis of the measurement variables was carried out. To verify the relationship between exercise needs and exercise self-schema, a multiple regression analysis was performed. The result showed that, firstly, there was a partially statistics significant difference between exercise needs and exercise self-schema according to their demographic variables. Moreover, there were positive influence on correlations among their exercise needs and exercise self-schema. Secondly, a positive effect of degree of exercise needs on exercise self-schema was found.

Recently the train indusrty come to the fore because of Punctual eco-friendly transportation system and becoming the main transportation. The construction plans for the trian depot for train's maintenance and storage increase constantly. For past few years there were many construction plans Bubal train depot Gwangju train depot Duckha train depot. Proper track distribution plan is important to carry out the design of railway depot for efficient maintenance operation and train storage. Through the proper design of track distribution plan we can shorten the moving time train movement distance waiting time in train depot. In this paper the verification of the track distribution plan's efficiency and appropriateness for railway depot as Bubal train depot's plan is studied and analyzed with the train depot management simulation program- Posrail(v1.0).

To overcome bad conditions of surroundings, construction cost is increased and environmental issues are sometimes rising. Because railway alignment have to be designed to improve efficiency of train performance. The efficiency of train performance is affected by train ability, railway condition, system condition etc. Among these factors, deceleration and acceleration are main factors that determine the capability of train performance. Designed railway alignment is currently verified by TPS(running time, average velocity, Input energy), however, there is no obvious criterion for applicability of deceleration and acceleration. Moreover, results due to changes of deceleration and acceleration tend to be derived irregularly in process of programming. Therefore in this study, problem of applied program is considered by investigating the results for modelled alignment. And efficiency for train performance is also examined by increasing the velocity limit of downward slope which is prescribed by Train Operation Manual.
