  • The purpose of this study was to analyze effects of teaching materials for elementary science gifted conception about object recognition. Elementary science gifted have misconceptions that they can see in lightness. They can not explain how a shadow is made. This paper reports in-depth investigation on elementary science gifted's understanding of object recognition focusing on process of light. A program is developed to elementary science gifted in the subject matter. The tutorial emphasizing the process of light consists of pre-test, worksheet, and post-test. The Tutorial has 4 steps; darkness and light, light on things, light reached eyes, structure of the eyes. Each steps has 2~4 experiments. Through the tutorial, we expect their misconceptions can be changed into scientific conceptions. For the research and analysis, a questionnaire is posed to 39 elementary science gifted at M Elementary School in D Metropolitan City. The first method of product analysis makes a comparative study of pre-test, post-test score, and hake gain each test. As a result, total score of all student was raised. And hake gain of pre-test(II) is 0.6, hake gain of post-test is 0.68. It is Medium gain. Also, elementary science gifted could understand how we see through the tutorial emphasizing process of light. And their misconceptions can be changed into scientific conceptions.

  • Even after learning electric current, elementary school students have various non-scientific conceptions and difficulties. Because flow of charge is not visible. Also elementary school students do not learn theory but phenomena, so they cannot transfer theoretical perspective to new situation. In this research, we have designed instruction based on PhET simulation visualizing flow of electric charge and applied it to 37 science-gifted students in elementary school for measuring conceptual understanding. As a result, six out of the seven Hake gains of question set are high gain and just one is middle gain because the students have understood the flow pattern of the charge through circuit elements such as light bulbs, wire, as well as battery with PhET simulation and it gives a chance to create various questions spontaneously about electric current. Also they become able to do spontaneous mental simulation without PhET simulation about flow of charges. This research, suggest that developed materials using PhET simulation could be used as not only program for gifted students in elementary school, but also the electrical circuit section in an elementary science curriculum.

  • The purpose of this study was to find the characteristics of the exhibition space planning methodology as 'Spatialization of Knowledge' through analyzation of the spatial structure in the contemporary museum architecture. The result of this study is expected to apply in designing an exhibition space and may become a target point. Further more this study can result a museum design to assist actual museum to fully function and play a role as a service facility for users by containing broad knowledge and fair understanding of user's needs in museum planning. Basic survey of museum architecture history will help visualizing conceptual structure of the museum exhibition and the 'Space Syntax' method has been used to make this conceptual data more objective. This study found that the contemporary museums most likely to include in its planning the various spatial organization in order to convey knowledge. The result reflects the needs of modern society which shows the design accepting individuality in society with variety of needs. And this also explains that museum space organization has to reflect various ways or methods of conveying knowledge. In addition, users have tendency to prefer more open space organization for easy access and approach in exhibition environment. It is clear to see the change in today's viewing pattern that the users prefer flexible exhibition space where they can be more proactive in receiving knowledge by following their own circulation over architecturally constrained circulation pattern within the exhibition area.

  • The recent entry and heated competition of numerous fashion brands in the luxury fashion market have all compelled luxury businesses to change. The issue of brand equity has emerged as one of the most critical areas for luxury marketing management. Despite strong interest in the subject, there is little evidence of how brand equity is created by marketing activities and what their effects are. This study identifies the effects of luxury marketing activities on the brand equity of luxury items, utilizing Keller's (2001) 'CBBE (Customer Based Brand Equity) Model' as a theoretical framework. Based on literature review, a conceptual model for brand signature, heritage, premium price, controlled distribution, and promotion on customers' view on brand equity was tested. To test the hypothesized building paths of luxury brand equity, statistical analysis were performed with an AMOS 7.0 program using a confirmatory factor analysis and structural equation model. The results were: First, luxury brand equity was defined in terms of four components (brand awareness/association, customer judgment, customer feeling, and customer-brand resonance). Second, the proposed conceptual framework of this study was partially significant. We can provide an effectiveness of Keller's CBBE model to conceptualize the building process of luxury brand equity; subsequently, marketers should develop core elements to position a brand strategy to create a competitive advantage.

  • This paper draws the home into the stream of information and communications technology (ICT) development. Considering that homes and our home life are constantly affected by persistent change influenced by ICT, it is remarkable that ICT has been relatively neglected as an object of research in the field of housing studies. This study provides an overview of conceptual movements in ICT/home relationships and their design and social impact through a critical discourse analysis. The conceptual movements must be considered by professionals in the field of housing and built environment to stay attuned to changes in the 21st Century. Diverse debates took place in the discourse about ICT in relation to home. The stream of thought was started by futurists who saw the electronic cottage as a solution to the social problems caused by the separation of work and home life in industrial cities. ICT has now entered a new phase, with WiFi P2P networks and location-based social media that encourage sharable homes. Based on the analysis of the discourse on ICT and home, we drew from three issues related to the paradigm shifts in homes in the context of ICT development to provide future directions for housing studies: from space programming to time scheduling, from individual ownership to shared access, and from live+work dwelling to live+work+community.

  • This paper examines the conceptual shift of wilderness and its legacy to the contradictory view of nature in landscape architecture tradition. In hunting and gathering societies, there was no dichotomy between the cultivated environment and wilderness. 'Wilderness' is a word whose first usage marks the transition from a hunting-gathering economy to an agricultural society. We can identify two archetypal responses to wilderness: classical and romantic. In the classical perspective, wilderness is something to be feared-an area of waste and desolation. The conquest of wilderness and the creation of usable places is a mark of civilization. For the romantics, in contrast, untouched wilderness has the greatest significance; it has a purity that human contact tends to sully and degrade. Wilderness for the romantics is a place to revere, a place of deep spiritual significance, and an object of aesthetic experience. In the Western world, the classical position predominated until the last two hundred years when the romantic concept began to gain more ground. The shift was made possible by the change in the way nature is understood. Modernity and modern science objectified nature. The transition of the concept of wilderness exemplifies the objectification and pictorialization of nature. Wilderness in the modern era is not different from the pastoral landscape which can be controlled by landscape architects.
