  • This paper begins with investigation of the race to unlock human DNA, and investigates the emergent areas of bio-technological innovations. This paper draws upon basic ideas from the research traditions of the diffusion of innovations in the competitive situations. To achieve the succesful diffusion of bio-technological innovations, following issues are suggested; clusters, alliances competence, core competence, consumer resistance, chasm phenomena, qualitative research, social network, and cross-culture. The better understanding of the diffusion of bio-tech innovations with empirical studies can complement research on the diffusion of bio-technological innovations and help in the development of a universal model for diffusion of high technological innovations.

  • Although claims and disputes may be never avoided in construction industry, until 1998, there are no systematic claims in the public sector in Korea. But, because of IMF, Contractors have been recognized that cost management is essential factor and contractual right can be demanded against the Public Orderer. Many affirmative effect such as, appearance of new professional service, prevention of lower quality construction, restrain of unnecessary budget expenditure, arrangement of duplicated or triplicated liability and revision of unnecessary administrative control may be anticipated through alleging claims, but in site representative manager and construction company may have ambiguous fear, somebody tried to allege claims. Therefore, to activate systematic construction claims, 32 public construction project claims alleged by contractors from 1998 to 2001 were analyzed, inactivated reasons of claims were examined and contractor's action plan to allege claims was suggested in this paper.

  • This paper tries to analyze how effective the problem posing method through Brainwriting can be on mathematical problem solving and creativity as a way to seek a new pedagogy to enhance student problem solving levels and creativity in mathematics. The findings of the study can be summarized as follows: First, the Brainwriting problem posing method improved students' abilities to alter problems, suggest new problems from multi-perspectives, and solve them. All procedures for such were obtained through discussions among group members. Second, the Brainwriting problem posing method resulted in positive effects on fluency and originality among components of creativity, but not on flexibility. That is, studying mathematics with this method helped students develop creativity levels not in terms of flexibility but of fluency and originality. Third, the interest rate in mathematics learning rose for those who studied mathematics by adopting the Brainwriting problem posing method. Finally, this study caused the Brainwriting problem posing method to be more deeply understood and appreciated from a new perspective.

  • The purpose of this study is to suggest the alternative strategies for teaching mensuration of parallelogram raised by Max Wertheimer, a gestalt psychologist who was particularly concerned with mathematics learning and teaching. For this, 77 student teachers were paper and pencil tested and we could get the 7 interesting and useful ideas from their datas in spite of the fact that not many student teachers correctly responsed. Analysing the datas, it turned out all the 7 ideas are related to equivalent transformation and can make children more easily to see the structure of area of Wertheimer's parallelogram than traditional approach.
