The purpose of this study is to examine factors that influence mobile video services' satisfaction. 362 users who use both DMB and mobile video services complete the questionnaires measuring 6 attribute level satisfactions and total satisfaction of mobile video services, TV contents broadcasting status in mobile video services. The data are analyzed by using frequency analysis, Chi-square test, t-test/F-test, multiple regression and moderated multiple regression. The results of the study are as follows: First, diverse contents, image quality, video streaming quality, user convenience, and data consumption volume affect total satisfaction of mobile video services. Second, TV contents broadcasting status in mobile video services doesn't show positive moderation effect on the relationship between attribute level satisfaction and total satisfaction. Based on the results, the implications and limitations of this study are discussed.

The purpose of this study is to investigate the effects of selection factors which include accessibility, trade area, spatiality, convenience, reliability, assurance on satisfaction. Also, the relationship among satisfaction, conversion cost, and reuse intention was examined. The survey was conducted for college students who had used coffee shops in the last month and 247 copies were used for the analysis. The study model was analyzed by the basic statistical analysis, factor analysis, reliability analysis, and structural model analysis using SPSS 18.0 and AMOS 18.0. As a result of analysis, it was confirmed that customer satisfaction was influenced by factors in order of assurance, accessibility, commerciality, reliability, and spatiality. Also, satisfaction and conversion cost have a significant effect on reuse intention. The result shows that the satisfaction of selection factors increases student customer's behavioral intentions and ultimately contributes to the improvement of coffee shop performance. Therefore, a coffee shop targeting college students needs a lot of interest in the taste of coffee, price, various menus and accessibility, trade area, and large space.

In order to suggest ways to enhance service competitiveness in cruise and destination, this study developed a measure of cruise tour service and analyzed the impact and relative importance on customer satisfaction. Specifically, for the service quality analysis, based on the SERVPERF model, the specialty of the industry was reflected through the arguments of tourism and transport logistics, and the three factors of cruise service quality and destination service quality were derived and utilized as measurement tools. As an analysis method, factor and reliability analysis were conducted using data collected via a survey. Next, correlation analysis was conducted to analyze the relationship between variables and regression analysis was performed to check the impact of cruise tour service quality on customer satisfaction. The study found that both cruise service attributes and destination service attributes had a positive effect on customer satisfaction and that the relative importance of service attributes was identified. Accordingly, it was found that the service quality should be formed by reflecting arguments in the tourism and transport logistics sectors and that the service should be further improved and developed according to the importance of the service attributes so as to enhance cruise tour products.

The purpose of this study is to find out whether changed interactions due to reformatting has a significant effect on the play attribute of children's play from an instrumental point of view. Based on the study of Roser Caillois theory of play (Agon, Mimicry, Area, Ilinx) and previous studies, a questionnaire was written and experimental design was carried out through brick stack which are most preferred in the whole development of children. Brick stack were selected from physical and electronic spaces and the survey was conducted with children's experiences by dividing into experimental group and comparative group. Correlation and T-test results, the brick stack by reformating showed significant difference in the play attributes (Agon, Mimicry, Area, Ilinx) of Rose Caillois and we found that the effectiveness of play is doubled in the electronic space. Play properties evenly distributed in electronic space brick stacking suggest that pleasure and fun can double.

Spatial data mining is a process to discover interesting relationships and characteristics those exist implicitly in a spatial database. Many spatial clustering algorithms have been developed. But, there are few approaches that focus simultaneously on clustering spatial data and assigning weight to non-spatial attributes of objects. In this paper, we propose a new spatial clustering algorithm, called DBSCAN-W, which is an extension of the existing density-based clustering algorithm DBSCAN. DBSCAN algorithm considers only the location of objects for clustering objects, whereas DBSCAN-W considers not only the location of each object but also its non-spatial attributes relevant to a given application. In DBSCAN-W, each datum has a region represented as a circle of various radius, where the radius means the degree of the importance of the object in the application. We showed that DBSCAN-W is effective in generating clusters reflecting the users requirements through experiments.

The purpose of this research is the estimation of a transfer ratio according to transfer time reflecting passenger attributes such as sex, age, income, job, the car ownership, and other variables with the assumption that a transfer ratio would be different depending on each passenger attribute. This research tested transfer time through a question-survey, estimated transfer time according to the passenger attributes using a data sample, and presented some applicable models about marginal transfer time for the case of the determination of transfer ratios according to transfer time. In this research the sample which had been surveyed for passengers walking to access a transfer station was used to test and estimate and the question was present walking time to the transfer time and the marginal transfer walking time.

The results of this study supported the proposed conceptual framework overall. The findings indicate that first, main facilities, subsidiary facilities, human services, accessibility, and peripheral conditions affected positively participant's satisfaction. Second, the high level city image and city attractiveness have moderating effect between some selection attributes of convention center and participant's satisfaction.

This paper is designed to address the extent of impacts that religious musicals may have upon on audience in contrast to the mainstream musicals by exploring choice attributes of Christian musicals, which are based on the stories of the Bible. Through empirical analysis, the paper shows that there is positive correlation between choice attributes and viewing satisfaction, while explaining choice attributes' impact on behavioral intention of audience, typically in word-or-mouth intention. It further shows that choice attribute of Christian musicals have direct positive impacts on both of behavioral and word-of-mouth intentions, which revisit intention is positively related to its reputation and the performance place. This study's significance lies in the use of Christian musicals to explore the complex interactions between choice attributes and audiences' behavioral intentions afterwards. However, it will also further benefit if future research include further mediating, control variable, including non-Christians.
