  • This study aims to understand why public information systems in agricultural fields have shown lower performances than other industrialized fields and industries and how these problems would be fixed and overcame. To accomplish this research purpose, this study would overview the previous studies on developing agricultural information systems in public sectors and would find out meaningful and considerable factors. This study would accept the methodologies of literature review and systems thinking approaches to understand the relationships among the found factors and to suggest the conceptual research model. Agricultural information system should take care to reduce implement and maintenance costs to reduce the negative relationships between costs and expected service value and between expected service value to perceived service value. Also, it should be understood that impersonal response would reduce the eager to use the services, so the government sectors should consider positively to adopt the concept of CRM even though the government sectors traditionally have ignored its necessity. The failure of public information systems/services may be caused not only by lack of the contents but also by the failure of the persistent post management.

  • The navigation in 3D virtual space is a procedure which must be carefully established in advance with understanding of a complicate perception process. Although current various desktop softwares are suppling developers with easier production circumstances in accordance with popularization era of interactive 3D media it is true that previous systematic conceptual study has been performed exclusively at specific institutions. Therefore, based upon the examples of virtual reality research reported by universities and companies core concepts giving the background for navigation realization and direct/indirect factors supporting substantial realization were analyzed and discussed in this paper.

  • Information visualization plays an important role to provide a conceptual comprehension of the information and should be adjusted and featured to reflect the characteristics of the domain to which it is applied. Product searching in e-Commerce is not an exception. In this paper, we present visualization techniques that are specified for effectively browsing the results of product searching. We considered visualization techniques including MapNet and Cluster Map and modified them to reflect the characteristics of the product domain. We consider two types of search queries: category searching and product property searching, and make it possible to include more detailed product semantics in their search criteria. We also provide a query refinement mechanism so that even users with rack of understanding the products may rewrite their queries for better results.

  • This study examined the knowledge structure constructed by children before formal instruction, and successive changes in the structural complexity of knowledge during the learning of the 'Structure and Function of Plants' unit. The researchers let the 5th graders draw the first draft of their concept maps in order to examine the pre-existing knowledge structure concerned with the unit and also four concept maps after completing every fourth lesson. Each concept map drawn by children on the basis of the previous one showed the degree of their current understanding on the structure and function of plants. The results revealed that only two levels of hierarchy and five relationships among the components of the first concept map(relationship, hierarchy, cross link and example) were proven to be valid in terms of conceptual relevance. According to the standard map, there was no change in hierarchy from the 2nd to the 3rd map, and in example from the 2nd to the 4th map. However, the gradual and successive increases of the scores in all components appeared in the children's maps throughout the unit. Knowledge restructuring occurred strongly in the early periods from the 1st to the 6th lesson, and the significant stable changes in tuning and accretion appeared throughout the whole lessons. The results also showed that there were no significant gender differences on the 5th grader's knowledge structuring.

  • In this study, we summarized and analyzed domestic research papers including science-related attitude in science education over the past 30 years, mainly teaching & learning methods. We reviewed 240 papers of experimental design in Journal of the Korean Association for Research in Science Education and Journal of Korean Elementary Science Education until the last volume of 2014 with results of statistical significance. The results are that students preferred group compensation rather than individual compensation. Also, students' active participation in class activities were effective in promoting students' science-related attitude. On the other hand, students' attitudes related to science did not show significant effectiveness in science class focusing on conceptual understanding. The results of this study regarding the positive or negative influence of teaching & learning methods in science will be expected to be useful when science teacher makes a selection the proper teaching methods.

  • Conception in learner's cognitive structure has a niche as species in ecosystems. The purpose of this study is to analyze the change of niche overlap of photosynthesis concept through instruction. The photosynthesis concepts were selected from literature review. Selected concepts were in 4 areas: Location of photosynthesis, reactants, products, and environmental factors. The subjects consisted 304 elementary students. The respondent marked the relevance between the presented concepts and each area on a scale of 1~30 points. The analysis of niche overlap in concepts was performed by changing in niche overlap graph, niche space size, and overlap index before and after instruction. The results are as follows. First, on the whole understanding level and relevance of the scientific concepts was increased through instruction as a result of learning. Second, elementary school students cognitive concepts in the form of chunking concepts through classification process. Based on the results, this study has the following suggestion. Students' conceptual ecologies and niche analyzed by this study will be used as material for development of instruction strategy.

  • The expansion of media art has not only developed the digital technology but also given lots of environmental evolution to improve various fields of design as the main topic of the 21st century. The purpose of this study is aimed at proposing the new design that integrates fashion accessaries with media art technology. This will be done by understanding the social environment in digital ages and studying technology of design based on a variety of literature about changes in our society, neo value, vision, culture and art with fundamental notion of media art. First stage for this study, put an idea into just fashion accessary design because it is not sufficient to incoporate fashion and media art technology. The presented OLED(Organic Light Emitting Diodes) in this study is a kind of display to be in a limelight in the next generation and can be applied to various field of design. media art simultaneously moved into the scope of artistic debates. As a result, we can found that the use of audiovisual introduced numerous new aspects to the conceptual and aesthetic engagement with questions of conception. Today, the presented forms of art and inter-action from the closed -circuit work to interactive media art installations to open process-exist as parallel possibilities.

  • The world has become one united world so that it is worthless to divide it into two; the East and West. In the 20th century, eastern perspectives proliferated in western science involving theology, philosophy and psychotherapy. In this time of various trends of ideas emerged minimalism, artistic and cultural current seeking simplicity and conciseness. This current of idea appeared about the time of World War II in visual art, and then expanded to other fields like music, architecture, fashion and philosophy in diverse forms. Minimalism is also presented in interior space with extreme form of simplicity and detail, revealing parts of the space as delicate and pure style with emphasis on purity of the space itself. In this research, demonstrate clear features of eastern view of space appeared in minimalism of interior design mainly in America. The reason the scope of study is limited to America is that America is the origin of minimal art and has been hub of modern design since the 1930s. The research, first, finds out the origin and conceptual idea of minimalism and features of eastern view of space. Based on this understanding, further study has been carried to discover relation of minimalistic interior space to eastern view of space and to analyze eastern characteristic expressed in minimalistic space by examination of cases pertaining to commercial space.

  • Recently, as emotional elements have been applied to many fields including marketing, architecture, and design, new understanding on and interest in sensibility are emerging. The sensibility, as opposite meaning to the reason, has been excluded from academic object, and researches in sensibility have been diversified for the meaning, scope, application methods and even application target of sensibility without consistency. This study aims to redefine meaning of sensibility by examining documents related to sensibility, and to examine the features of sensibility in design, especially in space design. Consequently, sensibility was defined to function as a filter which deals with numerous stimulative informations intuitively and uniformly while human gives significance to a stimulus. According to the examination on apparent features of sensibility and studies of sensibility engineering, the sensibility occurs not only by visual and physical stimulus but also by meaningful stimulus, and both are known to have mutual influence on each other. In space design, spaces of many purposes can be categorized into the spaces of routine and out of routine following the empirical time, and physical stimulus and interesting factor pursued by these spaces are inversely proportional. This study is meaningful insofar as it enabled to explain interaction between physical stimulus, meaning, and other factors within sensibility as a comprehensive concept by redefining its concept.

  • This study suggests a revised TAM (Technology Acceptance Model)-based performance evaluation model in MS (management science) education. Recently, many MS education programs are developed on the basis of computer and Internet communication technology. Previous researchers used TAM as an individual performance evaluation model, and proved that perceived usefulness and perceived ease of use are the substantive successful factors. This study provides a revised TAM-based conceptual framework for understanding what is involved in improving university MS education and what might be implied by conducting research on its improvement. It is argued in this research that three sets of forces and conditions have a direct and indirect impact on MS education ; first, each student has self efficacy and it is a critical determinant of behavior next, the use of Internet-based information system at MS education affects on the renewal of MS education : and finally, perceived usefulness and perceived ease of use have impacts on behavioral intention and actual system usage. This research concludes with suggestions for which direction this framework provides for future research on the premise and limits of efforts to renew MS education in university.
