Understanding various casual factors affecting the occurrence of freeway traffic crash is a backbone of deriving effective countermeasures. The first step toward understanding such factors is to identify crash risks on freeways. Unlike existing studies, this study focused on the unsafe vehicle maneuvering that can be detected by in-vehicle sensors. The recent advancement of sensor technologies allows us to gather and analyze detailed microscopic events leading to crash occurrence such as the abrupt change in acceleration. This study used an accelerometer to capture the unsafe events. A set of candidate variables representing unsafe events were derived from analyzing acceleration data obtained by the accelerometer. Then, the crash risk was modeled by the binary logistic regression technique. The probabilistic outcome of crash risk can be provided by the proposed model. An application of the methodology assessing crash risk was presented, and further research items for the successful field implementation were also discussed.

Maniac consumers have a ripple effect on marketing because they are the main body of trends and consumer economy. So It is very important that we should first read needs and wants - in other words, psychological motives. And then we should find maniac consumer segments. This is an exploratory study that was done to obtain an insight for the new maniac consumer market segmentation. It examined the definition and characteristics of digital maniacs in Korea, and it carried out a literature study on consumers who have a similar consumption trend as the maniac users as a pre-study. Also, it looked into the trends and values of the maniac community in Korea, using the previous study's scale for innovative consumers. Next, the study interviewed maniac users using the first data and focused on discovering and grouping the new maniac segments based on the results. The study analyzed the purchase behaviors, decision-making, attitude for involvement and potential needs of the digital maniacs in Korea, and it discovered the segments for the segmentation of maniacs so it could find out the disposition and status of the digital maniacs. Such approach can be used as a strategical due for maniac target marketing and design(customer-oriented marketing and design) in the future.

Main purpose of this study is to investigate the effect of the self core evaluation of local public officials on the customer-oriented public service provision. Structural Equation Model was applied to analyze the relationship between self core evaluation and customer oriented public service attitude. From theoretic point, establishing the relationship between psychological concept(self core evaluation) and attitude is contribution to existing literature in this area. Positive structural relationships between self core evaluation and customer-oriented attitude was confirmed from empirical analysis. While variable job engagement took intermediating role between self core evaluation and customer-oriented attitude. The result implies that organizational psychological approach might be a more effective policy measure to improve citizen's satisfaction for public services. For a extended periods, Korean government introduced various institutional arrangements to improve the customer satisfaction for public service. Hoever, the result was not satisfactory. The result of this study suggest psychological approach to improve public service customer satisfaction.

This research is to analyze reasons for violation of the Self Carfree day policy. It also analyzes satisfaction of the policy participation incentives. The results are that the violation rate is increasing if the drivers live in a zone which is highly energy consuming, which has low potential demand per bus stop and low trip generation per number of houses, which therefore requires more bus routes and bus services, and in which the drivers pay more car operating fees and show less tendancy towards participation even with the 5-10% oil price increase. The results are significant at the 0.05 level.

Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user-centered design methodology which uses the influential factors on the interactivity. This research is the first one of three linked- studies and categorizes the three main factors on the interactivity-Interface /Intersubject/Interaction. 'Interface' is the field for the interactivity. It will be the main subject for the second study. 'Intersubject' is the performer for the interactivity. Its specific attributes are analyzed in terms of user's needs for interactivity and six subdivisions are analyzed-functional & artistic need /external & subconscious need/info-communication & sympathy need. 'Interaction' is the performance for the interactivity. Its specific attributes are discussed in terms of behavioral interactive process and again sixsub-steps are analyzed-junction/immersion/ mental model/action/transformation/neo-experience.

This research is aimed at looking into the effect of the leadership of a leader of a guard martial art on majors' exercise results. For this purpose, this research selected the present students of guard science-related department as a population as of the year 2008, and finally used the data from the 259 questionnaires collected mainly from the first-year students to the third-year students among the man & woman majors in Taekwondo at colleges across the country by using convenient sampling. To achieve research results, this research set a statistical significance level at $\alpha$=.05. A guard martial art leader's positive leadership can help Taekwondo majors improve their exercise results, so a leader is encouraged to show a leadership pattern having respect for objective, reasonable majors in tune with the paradigm of swimming with the stream of times rather than a traditional leadership pattern-lopsided communication. In addition, Taekwondo majors' potential for growth could get bigger, and visible results could also increase when a leader makes a positive effort to induce majors into making definite suggestion of their vision and growth at an all-inclusive viewpoint.

With the aim of promoting the use of metropolitan railways, the present research developed a mode choice model for evaluating its competitiveness against passenger cars. A case study was carried out with Gyeongeui and Joongang line, and the area of interest was the direct operating railway between Ilsan and Guri station where the two lines intersect. The mode choice model was a disaggregate behavior model which used Stated Preference (SP) survey data, and the plot of competition was between private passenger cars and express trains. As a result, the mode choice model was established, and this model was used to analyze characteristics of passengers' time value and elasticity. It was shown that reducing travel time is more efficient than reducing travel cost when it comes to operating express trains in metropolitan railways. Therefore, policies designed for activating the use of metropolitan railways should expand direct operating service of individual lines and run more express trains in order to minimize transfer and in-vehicle time.
