  • Tour industry has been growing with increasing of people leisure time quantitatively as well as qualitatively. Especially, region tourist industry shows rapid growth because of the development of transportation and communication. Tourist contents that representing the region have been developing briskly. However there are many nominal tourist contents have just region differentiation with same attribute and composition. It has to be consider about tourist first not a contents provider or a developer. To be memorable tourist contents and to connect to consumption, understanding about tourist is needed. So 'Experience' will be standards when tourist contents is planned. In that sense, experience 4factors from Experience Economy and Challenge-skill model from Flow will be frames for giving shape to develop tourist contents. Experience 4factors from Experience Economy suggests 4factors for the superb enjoyment to tourists, and Challenge-skill model from Flow proposes balanced contents for understanding tourists. They will contribute to suggest planning frames for sustainable tourist contents and it lead to tourists' reinstation.

  • Through the teaching experiments, we investigated a series of processes for obtaining the differential coefficient at x=0 of the exponential function $y=2^x$ based on the process of constructing the natural constant e and the understanding of it. and all of the students who participated in this study were students who had no experience of calculating the derivative of the exponential function. The purpose of this study was not to generalize the responses of students but to suggest implications for mathematical concept mapping related to calculus by analyzing various responses of students participating in experiments. It is expected that the accumulation of research data derived in this kind of research on the way of understanding and composition of learners will be an important basic data for presenting the learning model related to calculus.

  • This study attempts to suggest the direction of Christian education for young children by analyzing concepts related to how they understand the faith. For this purpose, this researcher conducted interviews of seventeen young children who had not yet entered elementary school. Answers to ten interview questions were analyzed and research participants' understandings of belief and church were identified. The results have shown that participants consider faith to be religious practices such as prayer, praise and worship, the practice of good conduct, the key to heaven and providing direction and mission for their lives. Participants also revealed the acquisition and internalization of biblical knowledge and theological terms and listed parents, ministers or friends as the important role models of faith. They recognized the church as a place where religious practices are performed, where spiritual joy is felt and where pleasure is experienced because they do things they like. It is expected that these results would be used as the basis for future research regarding young children's faith and as the principles of the practice of it.

  • This paper focused on exploratory testing the organizational management area by examining conceptualized relationships between e-commerce usage type and organizational structure. The research model consists of three e-commerce usage type such as buy-side, internal, sell-side activities and four organizational structure dimensions like decentralization, specialization, formalization, and administration intensity. An interview and an e-mail survey of managers were used to obtain information on the variables relevant to e-commerce activities and organizational structure. The data resulted in response from 58 companies. Major findings of this research are summarized as follows: buyer related e-commerce activities is positively relate to the administrative intensity and the specialization, internal process is positively relate to the formalization, while customer related e-commerce is directly relate to the decentralization and the specialization in terms of organizational management.

  • This research premises that design failure in the market can stem partially from the gap between designer's communication intension through design and consumer's signification for design. Therefore, it's necessary that designers should examine and understand consumer's signification process for design factors or overall design images that they consider in the design process. For this, this research suggests that understanding consumer's signification process is possible by performing value categorization, consumer segmentation, value identification of main target consumers and relationship examination between value of target consumers and design attributes based on Means-End model by reviewing various theoretical backgrounds. In addition, this research suggests contents and methods for performing each step of understanding consumer's signification process. Also, Laddering was suggested as a method for the study and a case study was performed by it. Finally this research claims that understanding consumer's signification process can be one of the methods that decrease failure possibility rather increase success possibility of design in the market.

  • Problem solving and mathematical applications have been increasingly emphasized in school mathematics over the past ten years. Recently it is recommended that mathematical applications and modeling situations be incorporated into the secondary school curriculum. Many researches on this approach have been conducted in Korea. But unfortunately two thirds of these researches have been studied by graduate students. Therefore, more professional researchers should be concerned with the study related to mathematical modelling activity. This study is planning to investigate and establish i) the concepts and meanings of mathematical model, mathematical modelling, and mathematical modelling process, ii) the properties of problem situations introduced and dealt with in mathematical modelling activity, and iii) relationship between mathematical modelling activity and problem solving activity, and so on. To accomplish this, this study is based on the analysis and comparison of 11 articles published in domestic journals and 22 domestic master papers.

  • The social-democratic ideas which define the modern national Swedish idea have had an important influence on Swedish modern design during this century. Swedish designers found humanistic and democratic values in the traditional design style and they tried to create a modem style that was based on handcraft traditions as well as modern industrial aesthetics. Issues raised by Swedish designers of that time induded how Sweden was achieving a national identity through design and how design retlected changes within society. The purpose of this study is to investigate the social reformation policy of the Swedish government during the 1930-1970 period and its influence on Swedish modern design. This paper, it is hoped, will provide an opportunity to place contemporary Swedish design in a social and aesthetic context.

  • This paper first aims to reveal that, in the current trend of 'the participatory turn' in STS, there are divergent positions subtly different from each other, and that the understanding of these divergent positions can be significant to study the differences, similarities and interfaces between the various models of scientific governance discussed in STS and those in risk governance developed by risk studies. Secondly, this paper shows that theoretical differences among STS scholars on scientific governance and public participation goes back to the 1970s and 1980s, during which they first laid down the conceptual basis of STS. All ideas and theories have their own historicity. This article is about the 'historical epistemology' of the participatory turn of STS, and is to seek 'political epistemology' that can become a shared vision of STS.
