  • With the spread of internet, the digitalization and the knowledge informatization are in progress rapidly. Specially, numerous users make the various works and use the services on the web. For the most part, these works make use of the XML The XML shines the reusing of the documents because it is separated from contents and sues. Also, it can re-define the logic structure of the document for requirement of the developer. However, the XML document’s size is much larger than common text document because it handles the document type and adds numerous tags for representing structure of the document. To utilize the limited storage devices of Palmtop, PDA and so u, it is necessary to compress and handle the documents efficiently. Recently, the compression techniques for efficiently handling and compressing the XML documents are under way to solve this problem. But most of the existing researches don't support the query processing for the compressed XML documents. In this paper, we design and implement the XML compression algorithm that compresses the XML document and Processes the query of compressed XML document faster and more efficiently than previous techniques.

  • To answer whether it is proper to adopt wetland education as a part of the formal school curriculum, this study analyzed research trends and topics on wetland education and identified cases of adopting wetland education as a part of the formal school curriculum. Analyzing trends and topics on wetlands resulted in a recent shift of the focus of wetland education from the awareness and attitude towards wetlands to the ecological functions and ecosystem services that wetlands provide. In 2002, 18 Contracting Parties of the Ramsar Convention had adopted wetland education in the formal school curriculum. As of August 2020, the number has increased up to 42 countries. The globally increased awareness on the importance of wetlands seems to have led the positive change. Most of the cases analyzed and reflected in this study showed that the curricula were designed and applied not nationally but locally or school basis for efficiency.

  • The level and motivational basis of consumer involvement have been recognized as having important effects on purchase behavior. To explore the importance of hedonic aspects of involvement upon consumer purchase behavior, survey data on involvement degree and type concerning 8 product classes from 388 respondents was analyzed. Major findings of this study are summarized as follow. First of all, hedonic factor is evidenced as an important component of consumer involvement. In addition, hedonic dimension of involvement is proved to have significant effects on consumer purchase behavior in general. Secondly, analysis of the difference in behavioral tendencies between purchasing product with hedonic value(coffee) and utilitarian motive(washing machine) shows that consumers have relatively high in degree of brand differentiation, brand commitment, product knowledge in purchasing product with hedonic value. This means that hedonic aspect of product and thus hedonic involvement has not less important in predicting consumer behavior. Finally, several interactive effects, which suppot to and conflict against the previous research findings, between level and type of involvement upon purchase behaviors are detacted. This implies that hedonically induced involvement has moderating roles in the effects of consumer involvement on purchase behavior.

  • We analyze the tourist satisfaction of the Daegu City Tour which plays a big role in the local tourism boosting through '2011 Visit Daegu Year'. To analyze a causal relation among factors, we proposed a structural equation model consisting of four latent variables of the tour: motivation, expectation, satisfaction, and future behaviors. Using data from the actual tourists of the Daegu City Tour, we found out that tourists' motivation before the tour does not affect tourists' satisfaction after the tour. However those who have higher motivation have positive future behavior and those who have the higher expectation are more satisfied with the tour. Meanwhile, the expectation before the tour does not lead the future behavior but the satisfaction after the tour influences the positive future behavior.
