For the purposes of participation in research projects, living in a laboratory has become popular among male university students who tend to have less opportunity for nutrition education and overestimate their own health, suggesting possibilities of many undesirable practices of lifestyle and dietary habits. Therefore, this study was conducted to investigate and compare health-related lifestyle practices, dietary habits, nutrition knowledge, food preference and dietary behaviors of the male university students according to residence type. The subjects were 260 (34, 15, 44, and 167, respectively for lab-living, self-boarding, dormitory and commuting) male engineering majors in the Gyeonggi area. Self-administered questionnaires consisted of general characteristics, health-related lifestyle practices, dietary habits, fast food consumption, nutrition knowledge, preference for foods and tastes, and self-examination of dietary behaviors. Lab-living subjects showed many undesirable practices, particularly with more smokers (p < 0.05), irregular eating (p < 0.01), overeating (p < 0.05) and skipping breakfast (p < 0.01), compared to the dormitory students and more time in computer/TV usage (p < 0.05), overeating (p < 0.05), more frequent use of fast-food (p < 0.05), less nutrition knowledge (p < 0.01) and less intake of milk/dairy products (p < 0.01) and fruits (p < 0.01), compared to commuting subjects. More smokers (p < 0.05) and irregular (p < 0.01) and unrelaxed meal times (p < 0.05), compared to the dormitory group, and less intake of fruits (p < 0.01) and dietary fiber (p < 0.01), compared to the commuting group were shown as undesirable practices of the self-boarding group. Therefore, continuous effort should be made to correct undesirable health- and diet-related practices found in this study in order to improve nutritional status as well as general health by developing a nutrition education program and contents of lectures focusing on more specific problems according to each subgroup such as lab-living and self-boarding male university students.

자전거시설의 공급에도 자전거이용자가 시설이용을 기피하거나 다른 루트를 이용하여 주행하는 이유는 시설이 자전거이용자의 선호를 충분히 고려하지 않았기 때문이다. 본 연구의 목적은 자전거이용활성화정책의 주요 대상이 되는 통근시간대 자전거이용자의 통행특성과 경로선택에 영향을 미치는 요소를 분석함으로써 자전거도로의 계획 및 설계에 필요한 시사점을 도출하는데 있다. 이를 위하여 SP조사기법을 이용하여 이용자의 선호를 조사하고, 링크레벨 및 경로레벨요소로 구성된 로짓 모형을 도출하였다. 결론적으로, 본 연구에서 검토된 9개 요소가 모두 자전거도로의 루트선택에 영향을 미치는 것으로 나타났으며, 특히, 보조간선도로, 분리형자전거차로를 선호하는 것으로 나타났다. 따라서, 차선만으로 설계할 경우에는 분리공간(buffer zone)을 설치하여야 하며, 자전거차로를 설치할 경우에는 자동차의 속도를 50km/시 이하로 제한할 필요가 있다.

This paper proposes and examines the economic impact of infrastructure improvement on the San-En-Nanshin region in the Chubu area of Japan. We develop a single transportation computable general equilibrium (CGE) model for each subregion within the San-En-Nanshin region. The explicit modeling of the transportation infrastructure is defined based on interregional commuting flows and business trips, considering the spatial structure of the San-En-Nanshin economy. A CGE model is integrated with an interregional transportation network model to enhance the framework's potential for understanding the infrastructure's role in regional development. To evaluate the economic impact of transportation improvement, we analyze the interrelationship between travel time savings and regional output and income. The economic impact analysis under the CGE framework reveals how transportation facilities and systems affect firm and household behavior and therefore induce changes in the production and consumption of commodities and transportation services. The proposed theoretical model was tested by using data from the 2005 IO tables of each subregion and the 2006 transport flow dataset issued by the Ministry of Land, Infrastructure, Transport, and Tourism in Japan. As a result, the paper confirms the positive effect of transportation investment on the total output and income of the studied region. Specifically, we found that while economic benefits typically appear in urban areas, rural areas can still potentially benefit from transportation improvement projects.

The use of smartphones has grown rapidly over a short period of time, particularly for commuting news search, smart banking, and social networking services, and has had a significant impact on the pattern of contemporary life. Further, a wide range of applications are downloaded on to smartphones. This has also led a considerable number of complaints regarding these applications. In this study, we focus on the levels of dissatisfaction that users experience with smartphone applications and their effects on consumer complaint behavior along with the moderating effects of the complaint handling process and attribution. The aim of this study is to verify whether the following hypothesis--2 (low/high dissatisfaction level of smartphone applications)${\times}2$ (poor/excellent complaint handling process)${\times}2$ (internal/external consumer attribution)--is in accordance with the betweengroup design to build a factorial design experiment. The results of this study are as follows. First, the consumer's tendency to complain significantly influenced their dissatisfaction level. Second, consumer complaint behavior is modulated by the complaint handling process. Third, the external-attribution tendency of consumers was found to lead to more dissatisfaction than the tendency for internal attribution.

Recent data development has made it possible to analyze each individual's daily commuting by using transportation card transaction. This research utilizes about 1 million observations from the subway line no.7 of Seoul metropolitan transportation data. By using such a massive dataset, the authors try to identify daily travel behavior of morning commute and its possible relationship between subway usage and socio-economic factors. There are 4 main types of users and their travel behavior, and top 15 stations with the most users for arrival and departure are selected. Accordingly, 15 stations have distinctive characteristics including population density and the number of businesses around stations. To identify this fact, the 4 most populated stations are selected and their socio-economic factors are examined. According to the analysis, the most departure stations are generally surrounded by hihgly populated residential areas, whereas the most arrival stations are stood within the job concentrated districts.

There are a lot of traffic jams in the metropolitan area and the commuting time has been longer nowadays. So the urban people has been interested in the GTX(Great Train Express) project in Korea. The GTX is the train which runs at 200km/h speed in underground tunnels. If the train also operates at high speed in tunnel section, the pressure wave will happen and the uplift force of pantograph may vary abruptly. If the rigid trolley bar system is used in tunnel section, it is difficult to improve the commercial speed of train. In order to improve the train speed in tunnel section, this paper presents the new pantograph concepts which can change the suspension stiffness and deals with the dynamic behavior characteristics of pantograph according to the parameter variation.

Trip reduction policies are increasingly utilized in U. S metropolitan areas to address congestion and air quality problems. These policies typically focus on the journey to work and are aimed at reducing the amount of drive-alone commuting by providing transit and ridesharing incentrives. Severe air quality problems in Southern California have prompted the air polluation control agency for theLos Angeles metropolitan area to enact Regulation XV. The regulation requres employers to develop and implement a trip reduction program to achieve specified ridesharing goals. It si the most ambitious and far reaching such program implemented to date, and offers a unique opportunity to determine whether such programs can significntly affect travel behavior . This paper presents results from the first year of Regulation XV's implementation.
