In this study, water pollution sources of 14 major tributaries of Han river and characteristics of water quality for each target streams were evaluated based on water quality data in 2007.1-2009.12 (14 data sets) using a statistical package, SPSS-17.0. Cluster analysis over time and space for each stream resulted in 4 groups for the spatial variations in which type and density of pollution sources in the basins showed the greatest impact on grouping. Moreover, cluster analysis for the time variation in which rainfall, temperature and eutrophication were shown to contribute to the clustering, produced 2 groups, from summer to fall (July-Oct.) and from winter to early summer (Nov.-June). Four factors were found as responsible for the data structure explaining 71-90% of the total variance of the data set depending on the streams and they were organic matter, nutrients, bacterial contamination. Factor analysis showed main factors (water pollutants) changed according to the season with different pattern for each stream. This study demonstrated that water quality of each stream could produce useful outcomes when factor and pollution source of basin were evaluated together.

The team's performances were analyzed by evaluating the scores gained by their offense and the scores allowed by their defense. To evaluate the team's attacking and defending abilities, we also considered the factors that contributed the team's gained points or the opposing team's gained points? In order to analyze the outcome of the games, three prediction models were used such as decision trees, logistic regression, and discriminant analysis. As a result, the factors associated with the defense showed a decisive influence in determining the game results. We analyzed the offense and defense by using the response variable. This showed that the major factors predicting the offense were non-stop pass and attack speed and the major factor predicting the defense were the distance between right and left players and the distance between front line attackers and rearmost defenders during the game.

The classification of biotope type in major Korean cities was made based on the land use concept rather than the ecological concept of the land as the habitat of biological communities. Therefore, biotope type need to be reclassified according to ecological concerns and regional characteristics. This study attempts to clearly define various critical concepts regarding the classification of biotope type, such as classification hierarchy, classification criteria, classification factor, classification indicator, classification key, and classification standard. Furthermore, it also attempts to suggest the ways to improve the classification system of biotope type by sampling the cases of major Korean cities. The classification system of biotope type is required to have a coherent system that provides basic guidelines, standards and hierarchy with regard to biotic, abiotic and anthropotic factors, as well as classification indicators and classification keys.

Most online games today are provided via a website interface. Researchers found that various aspects of a game website importantly influence the success of the online game business. This paper aims at identifying key site-related quality factors affecting the success of online casual game websites and creating a model for measuring such success. To meet this end, we extracted basic factors from the literature and expanded them through a Delphi survey method in which domain experts were asked to identify key quality factors of online game websites. Then we performed a questionnaire survey using online game users for an empirical analysis. The results revealed that information quality, service quality, and system quality are all positively related to user satisfaction and that an increase in user satisfaction leads to an improvement in both gamer loyalty and business outcomes. However, it was found that gamers' loyalty does not necessarily increase business outcomes. The paper offers practical as well as academic implications based on the research findings.

Many B2B electronic markets (EMs) are struggling to survive because they failed to attract enough participants. Thus reaching critical mass of participants is one of the key success factors for various types of EMs. The main purpose of this study is to investigate factors that lead MRO (maintenance, repair, and operating) suppliers to participate in private exchanges (PE), the buy-side EM. This paper introduces the characteristics of the PE according to the classification schemes introduced in previous studies about EM types. Literature is reviewed on suppliers' adoption of inter-organizational information systems focusing on EDI adoptions issues. Data analysis based on incomplete contract theory and the social exchange theory is then presented. The results of this study show that the number of suppliers and subsidy are factors that influence suppliers' participation in PEs. Nonsignificant results relating to trust imply that suppliers who are invited to participate in a PE do not expect their off-line relationships with the buyer to be transferred to the PE.
