With the opening of the KTX(Korean Train Express) in April 2004, Express Train service started in KNR(Korean National Railroad). Each KTX train consists of 18 passenger compartments in total, such as of 4 first class car and 14 standard class car. And 2 compartments of standard class are serviced as a unreserved seat only. The Unreserved seat system of the KTX is convenient to the customer who wants to take a train without making a reservation. This study was designed to analyze the unreserved seat system of the KTX which is currently used, and to investigate the necessary conditions for gaining in public favor by developing the system.

본 연구의 목적은 체육수업에서 교사의 피드백이 중학생들의 내적동기 및 자기핸디캡에 미치는 영향을 분석하는 것이다. 이를 위해 B지역과 U지역의 중학생 450명을 대상으로 수집된 자료를 SPSS 23.0 프로그램을 이용하여 분석하였다. 타당도와 신뢰도 검증을 위해 탐색적 요인분석과 Cronbach’s α를, 각 요인 간 인과관계 분석을 위해 다중회귀분석을 실시한 결과는 다음과 같다. 첫째, 체육교사의 피드백이 중학생의 내적동기에 미치는 영향에서 교사의 부정적 비언어 피드백은 내적동기 하위요인인 재미·노력에 부정적 영향을 미치고, 격려·칭찬피드백은 재미·노력과 유능감에 긍정적인 영향을 미치는 것으로 나타났다. 또한, 부정적 비언어 피드백은 내적동기 하위요인인 긴장·불안에 정적인 영향을 미치고 격려·칭찬 피드백은 긴장·불안에 부적인 영향을 미치는 것으로 나타났다. 둘째, 체육교사의 피드백이 중학생의 자기핸디캡에 미치는 영향에서 교사의 부정적 비언어 피드백은 자기핸디캡에 정적 영향을 미치고, 격려·칭찬 피드백은 자기핸디캡에 부적 영향을 미치는 것으로 나타났다. 셋째, 중학생의 체육수업에 대한 내적동기가 자기핸디캡에 미치는 영향에서 중학생들의 재미·노력은 자기핸디캡에 부적인 영향을 미치며, 긴장·불안은 자기핸디캡에 정적인 영향을 미치는 것으로 나타났다. The purpose of this study was to analyze the effect of teacher feedback on middle school students’ intrinsic motivation and self-handicapping in physical education class. For this purpose, 450 middle school students participated in the questionnaire survey in the B and U cities. The collected data were analyzed by SPSS 23.0 program with several factors. Exploratory factor analysis and Cronbach’s α were used to verify the validity and reliability. Multiple regression analysis was performed to analyze the causal relationship between each factor. The study results are as follows. First, in the effect of physical education teacher’s feedback on the intrinsic motivation of a middle school students, negative non-verbal feedback, a sub-factor of teacher’s feedback, has a negative effect on fun and effort, which are sub-factors of intrinsic motivation. Encouragement and praise feedback have a positive effect on fun and competence. In addition, negative non-verbal feedback, which is a sub-factor of teacher’s feedback, has a positive effect on tension and anxiety, which are sub-factors of intrinsic motivation. Encouraging and praise feedback have negative effects on tension and anxiety. Second, in the effect of physical education teacher’s feedback on self-handicapping of middle school students, negative non-verbal feedback, which is a sub-factor of teacher’s feedback, has a positive effect on self-handicapping. Encouragement and praise feedback have a negative effect on self-handicapping. Third, in the effects of intrinsic motivation on self-handicapping on middle school student’s physical education classes, it is shown that the fun and effort, which are sub-factors of intrinsic motivation, have a negative effect on self-handicapping, and tension and anxiety have a positive effect on self-handicapping.

본 연구의 목적은 중학교 체육수업에서 교사의 자율성지지와 학생의 동료 간 관계성지지가 그릿에 미치는 영향에서 마인드셋의 조절효과를 분석하는 것이다. 이를 위해 B지역의 중학생 560명을 연구대상으로 하였으며, 불성실한 설문지를 제외한 549부를 연구에 사용하였고, 수집된 자료를 SPSS 25.0 프로그램을 이용하여 분석하였다. 설문지의 타당도와 신뢰도 검증을 위해 탐색적 요인분석과 Cronbach’s α를, 요인 간 조절효과 검증을 위해 위계적 회귀분석을 실시한 결과는 다음과 같다. 첫째, 체육교사의 자율성지지가 중학생의 그릿에 미치는 영향에서 마인드셋의 조절효과를 살펴본 결과, 교사의 자율성지지가 학생의 흥미일관성에 미치는 영향에서 고정마인드셋이 유의한 상호작용을 보임에 따라 정적인 조절효과가 있는 것으로 나타났다. 이외에 상호작용은 나타나지 않았으나, 교사의 자율성지지와 학생의 성장마인드셋이 노력지속성에, 고정마인드셋이 흥미일관성과 노력지속성에 유의한 긍정적 영향을 미치는 것으로 나타났다. 둘째, 체육수업에서 중학생의 동료 간 관계성지지가 그릿에 미치는 영향에서 마인드셋의 조절효과를 분석한 결과, 동료 간 관계성지지가 학생의 흥미일관성에 미치는 영향에서 고정마인드셋이 유의한 상호작용을 함에 따라 정적인 조절효과가 있으며, 교사의 자율성지지보다 동료 간 관계성지지와 고정마인드셋의 상호작용이 더 높은 조절효과가 있는 것으로 나타났다. 이는 체육수업에서 교사로부터 제공된 자율성지지보다 학생들이 또래관계 속에서 지지를 받고 고정마인드셋의 성향이 강할수록 흥미일관성 수준이 높은 경향이 있다. 또한 상호작용은 나타나지 않았으나, 동료 간 관계성지지와 학생의 고정마인드셋이 각각 흥미일관성과 노력지속성에, 성장마인드셋이 노력지속성에 긍정적인 영향을 미치는 것으로 나타났다. The purpose of this study is to analyze the moderating effect of mindset in middle school physical education class in the effect of teachers' autonomy and student's peer-to-peer relationship support on GRIT. For this purpose, 560 middle school students in B area were surveyed and 549 copies were used except for the unfair questionnaires. The collected data were analyzed using SPSS 25.0 program. In order to verify the validity and reliability, exploratory factor analysis and Cronbach's α were performed. In addition, hierarchical regression analysis was conducted to verify the effect of adjustment among the factors. The concrete results are as follows. First, First, after examining moderating effect of mindset in the effect of physical education teacher autonomy on the GRIT of middle school students, static moderating effect was found as fixed mindset showed significant interaction on the relation between teacher's autonomy support and student's interest consistency. In addition, even interaction did not occur, teachers' autonomy support and student's growth minds had a positive effect on effort sustainability. It showed that fixed mindset had a positive effect on interest consistency and effort persistence. Second, after analyzing the moderating effect of mindset in the physical education class in the effect of the relationship support among middle school students on GRIT, there was a static control effect as fixed mindset showed significant interaction on the relation between peer relationship support and student interest consistency. In addition, even there was no interaction, the peer relationship support and the fixed mindset of students influenced positively on interest consistency and effort persistence, and the growth mindset had a significant positive effect on effort persistence.

Due to the reduction of greenhouse gases and a sharp increase in the energy prices the world over, there is a growing interest in the railroad transport. In particular, in the case of containers which are the major item of railroad transport, a need for the switchover from the road transport to the railroad transport is being suggested, however, it is understood that the extent of the switchover occurring is only marginal. There exist many causes that account for the marginal extent of the switchover to the railroad transport. Some of them have to be dealt with at the policy level and efforts are needed to make it more efficient to use the railroad than other means of transport by improving railroad logistics facilities. Thus, the present study seeks to examine the possible measures for improving the railroad logistics facilities to promote the railroad transport.

The total length of Korean railway network is about 3,300km. Since it is of great scale in system view point, the systemization of GIS?based information system requires so much cost and time. One of the difficulties is due to the fact that GIS?based information system requires the feature database for GIS, which is generally built manually from many as?built drawing files. In order to build?up the feature database for GIS with ease, this study suggests the automatic data conversion from electronic drawings to make feature database for GIS. The proposed method can be applied to build large?scale railway facility management system at lower cost.
