In the ubiquitous computing environments. people usually carry multiple information technology devices with them. Personal device network (PDN) refers to the way how people connect multiple IT devices for their personal as well as professional purposes. Even though it has been Quite popular to construct the PDN in ubiquitous computing context, not much research has been conducted on how people actually connected multiple devices and what influences their methods of connection. In this paper we conducted a content analysis on community bulletin boards of IT devices and a contextual inquiry with expert users of PDN for investigating the configurations with which users connect multiple IT devices. Base on the results of two related studies, we identified three major types of PDN configurations, and key factors that influence the configurations of PDN. We conclude this research with guidelines to design a set of devices for each of the three configuration types.

This study examines modernist grid and boundary in the works of Toyo Ito - two of the most important notions characterizing the development of Toyo Ito as an iconoclast architect. Early in his career, Ito recognized modernist architecture's inherent tendencies to establish homogenous order and divide space by function was alienating people from their context. Ito identified the notions of modernist grid and boundary as the agents of Modernism which inadvertently served to impose this systematic order and severe separation. As a reaction against these tendencies, Ito sought to avoid the use of modernist grid and blur boundary in his architecture. In Ito's career spanning over four decades, he engages in an exhaustive inquiry seeking to modify these two core elements of architecture. This study investigates these two notions in Ito's works and examines the significance of the architect's exploration in the context of Japan's Modernism.

The purpose of this study was to explore how science docents developed their expertise in the context of situated learning where two experienced docents played roles of mentors. Two experienced docents as mentors and six participating docents as mentees interacted in the community to develop exhibition interpretation strategies to be more professional in interacting with visitors through the workshops developed by the researcher. To figure out how docents developed their expertise in exhibit interpretation, the researcher collected the data from docents through observation, artifacts, and interviews as well as surveys. The result of this study included that participating docents formed new perception about scientific inquiry as well as scientific literacy and they developed professional skills of planning, implementing, and reflecting of exhibition interpretation in the context of situated learning, where docents formed alliance one another. It is recognized that participating docents' passions to be professional in exhibition interpretation and two experienced docents' wills as mentors made dynamic interaction in pursuing the same aim of docents' expertise in exhibition interpretation.

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.

The purpose of this study was to develop teaching modules related to Earth Science courses in order to enhance scientific inquiry skills of middle school students. A 'process skill-centered' module was developed to induce scientific process skills, while students explore specific scientific context. A module consists of several activities, and each activity focuses on a specific science process skill. Modules were designed such that the skills would improve depending on the completion of the module. To evaluate the effectiveness, field workshops for middle school science teachers were done twice. Science teachers, who were participants of the workshop, commented that the activities in each module were suited to enhance students' interest in science. They noted that scientific inquiry skills would be developed from each activity. Students responded that the activities in the modules were interesting, and it was a good experience to do them by themselves. Students were the focal point in class, not teachers. This enabled teachers to evaluated each student's achievement level, and provide a proper feedback. Hence, applying these modules in classes should enhance the students' scientific inquiry skills.

In this study, we investigated actual cases of assessment science teachers conducted and the cases they preferred in a typical situation based on the curriculum in the context of 'Scientific Inquiries in the History' of Scientific Inquiry Experiment. A questionnaire composed of descriptive questions was developed and a survey was conducted with 70 science teachers with experience in teaching 'Scientific Inquiries in History'. Interviews were conducted with eight of them. The assessment cases were analyzed in terms of the assessment areas and assessment methods, and the results were compared. The analyses of the results revealed that 'scientific inquiry ability' accounted for the highest ratio of the assessment areas in the actual cases of assessment. There were few cases that assessed the core concepts presented in the curriculum, 'the nature of science' and 'scientists' inquiry methods'. The assessment methods were greatly biased toward the report method and various assessment methods were not used. In preferred cases of assessment, the ratio of cases that assessed the core concept increased slightly, however the frequencies remained at a low. As for the assessment methods in preferred cases of assessment, the measurement methods decreased, the performance methods increased, and the informal methods which were not shown in the actual cases appeared. However various assessment methods were still not used. The causes of the survey results were analyzed based on the opinions of the teachers who participated in the interviews. Based on above results, plans to actively conduct NOS assessments in Scientific Inquiry Experiment are discussed.

Recently KISTEP(Korea Institute of Science and Technology Evaluation and Planning) held an open forum for examining 'the Manuscript of National Science and Technology Standard Taxonomic System'. I submitted my opinion letter to the forum because I thought that the matter of setting the standard taxonomic system for Science and Technology is so closely related to the research concern of STS that it needs checking from the viewpoint of STS. This paper primarily focuses on making a criticism of and constructing an alternative to the mamuscript, but it goes so far as to ground the matter upon the STS viewpoint. I propose that we interpret an open forum related to science and technology as an example case of the community of inquiry. Further I try, standing in the context of learning to form a model of doing STS interdisciplinary research. In the context of decision I point out the problem with the 'scale' principle involved in categrizing criteria of the taxonomic system and argue that the problem leads to omitting STS from National Science and Technology Standard Taxonomic System although STS takes up science and technology themselves as its research concern proper. In the context or teaming I seek to set up a typical case study or STS. One of the typical STS research tasks is trying to construct a positive alternative to as well as make a criticism of a given suggestion, for clearer alternatives will, in him, provoke sharper criticisms or safer acceptances. I hope that the model in this paper will exemplify such an alternating procedure of criticism and acceptance.

In the elementary science classroom, inquiry-based learning activities are often limited to students' hands-on experiences. As a result, students often overlook core concepts they are supposed to acquire from the inquiry activities and show difficulties in applying those concepts in a real life context. To make a connection between the hands-on activities and the concept leaning, a small-group discussion can be considered. In this study, we designed a team-based learning (TBL) model for the elementary science classroom. We developed teaching and learning materials for the "Comfortable Environments" unit in the 6th grade curriculum based on the TBL model. After appling the model with 32 6th grade students, we compared the TBL participants' level of concept understanding and attitudes toward science before and after the intervention, and also compared them with their counterpart control group who participated in a traditional classroom. The results showed that the level of concept understanding of the TBL participants were higher than that of the control group. However, there was no statistically significant difference found in attitudes toward science between the TBL participants and the control group. In addition, the interviews with the TBL participants showed that they positively perceived the TBL experiences.

The purpose of this study was to examine levels of claims and evidence produced by 53 secondary science teachers. Levels of claim and evidence produced by the teachers in this study are various depending on themes. For a problem integrated several science concepts, there were many teachers who produced claims and evidence in a level of 1 or 2. The participant teachers presented claims and evidence in a level of 3 or 4 for a problem related to chemistry concepts presented in chemistry textbooks. Professional development programs should be provided for science teachers to help them develop understanding of argument structure and construct high quality of claims and evidence.

This study examines this intriguing idea In the context of the E-commerce involved in inquiring and purchasing books on the internet. Survey data from 154 potential users support and offend this hypothesis. The data show that both familiarity with an internet vendor and its processes and trust in the vendor influenced the respondent's intentions to inquire about books, it is primarily people's dispositions to trust that affected their trust in the vendor. The data support the basic assumption of the study both trust and familiarity influence E-commerce. Also, the study show that both trust in a Internet vendor and familiarity with the vendor and its procedures influence two distinct aspects of I-commerce intentions in book selling sites: inquiry and purchase. The influence if familiarity and trust are strong on people's intentions to purchase. The study show that trust and familiarity are distinctly different constructs, and that trust is significantly affected by familiarity, and not only by people's disposition to trust. The research model thus shows both trust and familiarity influence behavioral intentions. In this study, familiarity was introduced primarily as an antecedent of trust, while its role in increasing I-commerce was not as emphasized as that of trust. However, the importance of familiarity might be greater: familiarity influences both purchase intentions and inquiry intentions only slightly less than trust does.
