The purpose of this study was to examine the effectiveness of utilizing a concept map as an instructional strategy to promote student achievement through semantical learning in elementary school on volcanoes. To analyze student achievement in understanding the concept of volcano, quantitative and qualitative analyses were performed through a written test for two different groups that were composed of 80 sixth-grade students: a control group that attended class using the conventional strategy and an experimental group that attended class using concept maps. The results of this study were as follows: First, the use of concept maps in class is effective in learning because of the higher understanding of the group that was using concept maps in the achievement assessment. Second, in their post-instructional understandings, no significant differences are shown between middle- and low-ranking students statistically, but a significant difference is shown between high- and low-ranking students or between high- and middle-ranking students. This indicates that the use of concepts maps in a class is more effective for the middle- and low-ranking students than for the high-ranking students. Third, in the repetitions of classes, the students learning with an aid of concept maps became accustomed to structuring the concepts of their learning subject in categories of relationships, hierarchies, cross-links, and examples easily.

Although market orientation as the implementation of the marketing concept has long been a major subject in marketing, firms with market orientation do not necessarily come with high performance, showing mixed results in literature. There have been attempts to link market orientation-firm performance until recently with different mediators, but the appreciation on market orientation has been faded in practice. This study focuses on two possibilities for the causes of these problems. 1) Previous studies have overlooked the qualitative aspects of market orientation, 2) have focused on the performance at corporate level. To provide a generalized performance-generation framework, this study demonstrates the market information quality as a moderating variable and introduces the task performance of employees as a universal mediator between market orientation and the firm performance. As the result of this study, we confirmed the positive role of the market information quality and employees' task performance in market orientation-Firm Performance. The relationship between market orientation and employee's task performance becomes stronger when market information quality is high in value. We highlighted the performance generating mechanism of market orientation, regardless of context. This research provides new insights for marketing scholars and managers with regard to both activities and quality of market information and how market orientation affects individual and firm level performance.

This study attempts interpretation of vertical montage expressed in assoziation montage focused on animation, Paprika. Montage has been continuously studied by Pudovkin, Eisenstein, Jacques Aumont and others till now. However, existing studies focused on the visual image of montage. Image is made of visual element and aural element. These two interact with each other and maximize the effect. It is believed that the study subject can be approached in more depth, if aural elements would be analyzed based on the assoziation montage which analyzed visual image in previous studies. Accordingly, this study explores and analyzes how vertical montage has been used in logical montage and optical conflict montage and what meanings they generated. The analysis results suggested followings. In logical montage and optical conflict montage, vertical montage complemented visual image by natural concurrence as a whole. Vertical montage also showed linked relationship, which reflects overall emotion by melodious concurrence. In addition, when there was melodious concurrence at certain time, place or unclear space, the elements showed continuity which made them link with relationship. However, when the role that cuts that continuity, in other words, when the tonal element, which let audience partially immerse, would be properly used when the space and time would change or get reversed, the effect was maximized. It also expressed a turning point of an event and enhanced the concentration of audience on the characters.

This study attempts to specifically analyze green volume and scenery characteristics by classifying the streets in Seoul and suggest improvements accordingly. The subject streets for research were limited to those that have high occupancy ratio and are wide enough to have a big potential in improving green volume. In terms of green volume and scenery according to the types of streets, Platanus occidentalis and Ginkgo biloba were most common regardless of the street type, and the green ratio was 51.6% in residential areas, 50.4% in commercial areas, and 43.7% in business areas. Apart from the residential area, there was almost no green areas, and the ratio of green coverage was 71.0% in business areas, 64.0% in green areas, 37.3% in residential areas, and 36.2% in commercial areas, while the green volume coefficient was $1.9m^3/m^2$ on average. Based on the study results, it was set as a goal to provide the residential areas with a green community space and flowering trees throughout the year for scenery, and commercial areas with flowering trees and maples to emphasize the stores' image while not interfering with service and walking. For business areas, the goals were to improve green ratio and create streets that suit the urban image, and to set up spaces to provide habitat for wild animals with multi-layer planting and link to surrounding forests.

Urban infrastructure is a core of urban growth management which concerns with location, time and costs of development. Despite an inevitable link between development density and infrastructure capacity in urban areas, little study have been performed. For this reason, development activities are undergone without any clear evidence or analysis. The main purposes of this paper are to build subject maps of urban infrastructure capacity which illustrate the level of education service and road capacity, and to give reference standard for development decision at given location. For these purposes, the case study of the high-rise multi-purpose buildings in Daegu metropolitan city is performed. The main findings are follows. First, road ratio is high in the CBD and its surrounding areas as well as rural area, and low in areas of manufacturing, parks and military use. Second, educational facility, represented by the number of student per classroom of elementary school, is fairly abundant across the city, especially in the CBD and rural areas. Third, the high-rise multi-purpose buildings have been built in population-losing infrastructure-abundant areas, in general. Based on these results, this study concludes that the high-rise multi-purpose buildings may induce population-inflow and have low possibility to bring about overly dense developments.

"Yixuerumen" is a comprehensive medical text published in the Ming-dynasty by Li Chan(李梴). In this text, Sanghan(傷寒, cold damage) is categorized among external contraction(外感) with much emphasis. The subject of this study is the verse "The Principal and secondary aspects must first be decided." and its annotations in the in the Sanghan chapter of "Yixuerumen". The complex theoretical structure of this verse was firstly analyzed, together with the historical background of how and why Li Chan adopted this concept. The Pyo-Bon concept is the contrast between phenomena(標) and its underlying source of motivation(本). The methodology for this study was to compare and analyze this main verse with contents on Sanghan and Un-gi(運氣) within the text, while reviewing historical theories explaining the physiology and pathology of the human body in terms of the Pyo-bon(標本) concept. As a result, we discovered that the Pyo-bon(標本) concept used in the aforementioned verse of "Yixuerumen" matches the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory of Un-gi(運氣). Li Chan created the connecting link in understanding the Three Eum Three Yang diagnosis system through the viscera/bowels theory(臟腑論) by adopting the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory from Un-gi. Li's work lead to several changes in the field of Sanghan. First, Li understood the disease pattern of Sanghan by using the accumulated knowledge of the viscera/bowel theory during the Jin-Yuan dynasty, and developed a medical perspective that observes the disease pattern based on the body's essence gi(精氣). Second, he set the category of the Sanghan-Three Eum Three Yang disease pattern, establishing a separate guideline. Third, by adding knowledge of herbs to the accumulated knowledge of the viscera/bowel theory, the process of diagnosis and herbal application were made explicable. On the other hand, in the process of interpreting the 三陰三陽 diagnosis system with viscera/bowels theory, theoretical inconsistencies appeared, of which Li tried to mend by several means. The results of the research on "Yixuerumen(醫學入門) the Sanghan chapter(傷寒篇)" calls for further studies, as it has effected both "Dongeuibogam(東醫寶鑑) the Sanghan part(寒門)" and "Dongeuisoosebowon(東醫壽世保元)" as well.

Recently, BIM(Building Information Modeling) has been applied to the infrastructure such as road and bridge, and information about the outside environment of buildings is needed for maintaining and managing the large urban facilities. In addition, the convergence between spatial information and Big-data has a large potentiality, in respect that considerable profits and developments in other application problems such as various simulations and urban plans, national land security, may be brought about on the basis of the interoperability of information between BIM and GIS. Therefore, this study attempted to suggest the development direction of a model integrating building for spatial information analysis and city on the subject by comparing and analyzing difference between information system and shape expression of IFC, CityGML and LandXML to efficiently link information between IFC as a standard model of BIM and CityGML as a standard model in the GIS sector and to prepare a basic fusion strategy and a method of utilization between BIM and GIS. The result of the study are as follow. Firstly, contents and structure of IFC, CityGML and LandXML are compared and analyzed. Secondly, the development direction of iBUM(Integrated Building and Urban Model) suggested, which is based on convergence technology for analysis of space information. Finally, a strategy and method of the BIM and GIS are proposed in the iBUM environment.

The percentage of senior citizens is increasing in Korea and it is expected to become an "aging society". Problems with the elderly are becoming a big concern, such as physical and mental illness, losing their jobs and having difficulties at home. But, the silver generation, as they are being known, has changed a lot these days. With the aid of medical developments, the elderly's lifespan has become longer, making them more independent and active. Senior Welfare Center's are places where the elderly can spend their golden years in comfort, meaningfully. Senior Welfare Center's these days provide many different programs, which naturally lead to an increase in elderly users. With the rise in welfare centers and users, research on the subject also grew. As this topic has only recently become an issue, there were not many spatial structure studies considering elderly movement. Therefore, there should be spatial structure research that considers older users space awareness and how it can be managed effectively. The goal of this study is to present basic resources for providing a comfortable senior welfare center for elders. This will be based on quantitative analysis derived from spatial structure research along with special construction characteristics based on the institution's general plan. As a research method, Senior Welfare Center's will be categorized into corridor type, hall type, and hybrid types which then be reproduced into a j-graph. Based on this, special structure characteristics and connection links will be comprehended. Then the connection link will be analyzed based on the space syntax result calculated from each type's integration, connectivity, control value, and intelligibility. The analysis result shows that Senior Welfare Center j-graph's average arrangement is hybrid>corridor>hall types. Those elders lacking awareness need easily perceivable spatial structure's and hall type's would be the best choice to increase their awareness as it has high articulation. However, hall type's would be difficult to construct with the size increase, so hybrid type would be the next logical solution. Space with relatively high articulation will need to be planned in hybrid type's where rest areas can be created within the halls in the Welfare Center in connection to its corridors.

Multiculturalism in education are different from each countries, It is needed to practice multicultural education in many fields facing changes to multicultural society in Korea. This study demonstrates on the relationship of social friendliness and stereotypical attitudes toward Saeteomins (North Korean refugees) to the knowledge of North Korea. Saeteomins are special in the respect of linguistic and ethnic homogeneity of Korea. They have to adapt themselves to new circumstances like other immigrants from abroad. At the same time they have cultural senses of difference to live in a divided country in spite of ethnic homogeneity. It is important to get openminded attitudes to be receptive to cultural diversity in the respect of getting multicultural sensitivity. On account of a growing migration of Saeteomins family, Saeteomin students have difficulties in adapting to Korean society. This study focuses on the point of middle school (general) students' view to Saeteomin students, who have experiences to meet each other. There are three categories of contents knowledge, common sense of North Korea and social issues related to North Korea in this paper. All of them are significant to social friendliness and stereotypical attitudes toward Saeteomins to the knowledge of North Korea. That is important point to contents construction in curriculum about North Korea. This study is meaningful to find the potential to link contents knowledge of subject to multicultural education practice in the process of curriculum change especially in relation to the knowledge of North Korea in 2007.
