Research relevant to the electronic commerce tends to either overestimate or underrate the role of Information and Communication Technology (lCT). There is both technological skepticism within the social science circles and technical optimism within the engineering and computing field. Each perspective seems to have a limitation in adequately explaining the phenomenon of electronic commerce diffusion. Therefore, this research attempts to explore major characteristics of Web-based shopping systems as enablers of new business, concerning both the technical and business aspects in contemporary electronic commerce settings. On this basis, this paper addresses a configuration model of WBSS on the harmonious perspective concerning both the technical and business issues. It is our hope that both technical perspective and business perspective for exploring WBSS's configuration model presented in this paper can be an initial step towards a more balanced debate of ICT role, for electronic commerce.

The purpose of this study is to investigate design elements to strengthen apartment communities in territoriality perspectives. To this end, the study first identified the functions of territoriality to communities, and examined precedent studies on community planning. Then, looking into actual apartment, the study analyzed design elements of the apartments by territoriality functions, and found significant community-building and community-strengthening elements. The results of case studies are as follows: Specific design elements are 1) both individual and shared places from the perspective of possession, 2) both physical boundaries including visible mark and physical demarcation, and emotional boundaries including space arrangement and visual expansion from the perspective of boundary-regulation, 3) both physical proximity, such as providing space for physical encounter and easy access, and emotional proximity such as homogeneity and intimacy from the perspective of proximity 4) design differentiation and adoption of the design concept to express the identity of the community from the perspective of proximity personalization.

The purpose of this study is to assess the changes that occur to pre-service mathematics teachers by using survey on the self-reflection during their education practices. For four weeks of the education practice period, the changes to pre-service teachers are analyzed from teaching and learning perspectives. The teaching perspective is sub-categorized into lesson contents, teaching methods, and evaluation on teaching, and the learning perspective is sub-categorized into monitoring on learning, support for learning and evaluation on learning. The analysis shows that significant changes occur in teaching contents from the teaching perspective and in all the sub-categories from the learning perspective. Based on the analysis, preservice teachers are suggested to utilize self-reflection programs during their education practices to promote their professionalism in teaching.

The Hansel-Spittel constitutive model requires a total of nine parameters for flow stress prediction. Typically, the parameters are estimated by least squares methods for given tensile test measurements from a deterministic perspective. In this research we took a different approach, a probabilistic viewpoint, to see through the development of the Hansel-Spittel constitutive model. This perspective change showed that deterministic least squares methods are closely related to statistical maximum likelihood methods via Gaussian noise assumption. More intriguingly, this perspective shift revealed that the Hansel-Spittel constitutive model may leave out deterministic trends in residuals despite nearly perfect agreement with measurements. With tensile test measurements of AA1070 aluminum alloy, we demonstrated this deficiency of the Hansel-Spittel constitutive model, suggesting room for improvement.

This study discusses the interpretation and application of a post modern perspective to child development knowledge and early childhood teacher education. The survey of literature focused on the post modern approach to child development knowledge and early childhood teacher education, research in the reassessment of child development knowledge as it is challenged by the post modern perspective, and deconstruction of both child development knowledge and early childhood teacher education. It was concluded that child development knowledge is necessary but insufficient to early childhood teacher education. In the post modern perspective, the movement toward fostering "reflective practitioners" and basic knowledge base is more significant. Therefore, the responsibility of academics is to walk the fine line between presenting a formal knowledge base so that students gain assumption to guide their thinking and practice, critiquing both theory and derived practices.

This paper reviews the emerging literature on innovation policy from a practitioner's perspective, reviews the policy implications of an evolutionary perspective in economics, and identifies newly emerging areas of innovation policy analysis. We show that an innovation system is a dominant policy discourse, that there are limits of policy implications from an evolutionary perspective, and that there is a need for explicitly policy motivated analysis grounded in a broad evolutionary perspective. Innovation policy studies are an area in pre-paradigmatic stages whose dynamism originates from the interaction of theory, policy, and policy learning. The limited usefulness of policy implications derived directly from either conceptual or empirical analysis requires more explicitly policy focused research.

This study aimed to understand students' learning in elementary science classes in terms of participatory perspective. Participatory perspective is based on the participationist views on learning. Based on the participatory perspective, this study used two concepts of participationism: 'the changes of learning on commognition' of Sfard (2007) and 'the identity' of Wenger (1998/2007). Based on these concepts, four episodes of an elementary science class were analyzed. The results showed that students carried out their learning from objective-level learning to meta-level learning. And students defined who they are by identifying and negotiating scientific meaning during the learning. These results showed students become members of science community through their participations in science class.

The purpose of this study was to understand consumer use and awareness of refill-products in perspective of environmental protections. One hundread seventy-four married women living around Cheongju-city were selected because married women are the major buyers of refill-procucts. The major findings were as follows: 1) While detergents refill-products were found to be the most favorable one, cosmetics refill-products were found to be the worst favorable. 2) Married women complained different quality and quantity between refill-products and nonrefill-products in general. 3) Price was the most important reason to use refill-products rather than environmental protection. 4)The more respondents had refill-products information, the more respondents used refill-proeucts 5) The level of consumer awareness of refill products examined in perspective of enviornmental protection was found to be very high(3.3/4). 6)There was no significant relatioships between consumer use and awareness of refill-products examined in perspective of environmental protection.

As a seedbed for American Public Administration, Traditional Reform Perspective (TRP) produced Wilsonian formulation of administrative science in modern academic setting. From the beginning of the second half of the twentieth century, ideas were transported into Public Administration scholarship. New Reform Perspective (NRP) entails a belief that these reasonings are largely based on assumptions of Economics. Looking into this belief is a necessary condition, if not a sufficient one, for answering the question: Does NRP hold in the study of administration? This initial reading, though somewhat primitive, tries to set up a proposal for identifying a meaningful context for understanding the situation. As a representative version, Wilson's original perspective must be reconsidered in order to articulate the field of study within traditional reform context. According to NRP, new administrative theories are the results of the influence of economic reasoning into the field of Public Administration. Therefore, rereading of Tiebout's 'Pure Theory' and Ostrom, Tiebout and Warrens's 'Theoretical Inquiry' is a prerequisite to satisfy this particular condition.
