For the study of the development of Asia map made by european map makers, one should consider Gog and Magog which existed in the maps for more than 700 years. Gog and Magog are described as an apocalyptic people in the Bible and medieval literature, and they are important elements in medieval mappaemundi and early modem world maps. This study classified representation types of Gog and Magog in old western maps. Maps were classed in to six categories according to the location and ethnic groups which they represent, and they were discussed in cartographic context. The maps until the fourteenth century place Gog and Magog, shut up by Alexander, near Caspian Sea. In the fifteenth century, Gog and Magog were described as Closed Jews in maps. From the sixteenth century they appear in the far northeastern part of Asia and they are named as Amagog or Ung and Mongul. In the mid-seventeenth century, they are located in Eastern Siberia by French cartographers. But with the expansion of geographic knowledge, Gog and Magog disappeared completely in the eighteenth century. In general, God and Magog were represented on the basis of traditional lore rather than on the Bible, and they became one means of mapping others of European community.

Mountains have significant influences on the atmospheric environment. The Korean Peninsula consists of approximately 70% mountainous area with numerous mountain ranges and peaks. The initial classification of mountains in Korea was made by a Japanese scientist from 1900 to 1902. In fact, the Japanese study created too many names of mountains to maintain, which led to confusions. The purpose of this study aims to simplify the previous names and classification of mountains in the Korean Peninsula so that they can be utilized for educational and general purpose of the society and educational institutions. Through this study, we name various mountains as one name "Korea Mountains" which is classified as the secondary world-mountain class stretching from the Korean Peninsula to northeast China (southern Manchuria). The Korea Mountains connect the third class regional medium-scale mountains of Jirin, Hamkyoung, Taebaek, and the fourth mountain class, 8 small-scale ranges including the Liaoning, Yaenbaen, Hambeuk, Pyoungbeuk, Whanghae, Charyoung, Kyoungsang and Namhae Mountains. The major mountains in the Korean Peninsula are normally influenced by the general circulation of the atmosphere of the world. The atmospheric conditions are modified on the up-stream and down-stream sides; there is a need for continuous monitoring of the atmospheric environment which impacts the ecosystem and human society.

This study is a research synthesis analyzing how field geology education is conducted in domestic and foreign countries in the recent 20 years and how it reflects the characteristics of authentic geologic inquiry. For these purposes, we first drew five elements of inquiry in field geology (observation, representation, abductive reasoning, spatial thinking, and diachronic thinking) considering the field geologists' actual research method as well as its pedagogical significance in science education. We developed analysis criteria for field geology education. The 53 cases were analyzed based on each element of inquiry in field geology and its sub-elements, and also the tendency of overall elements. As a result, observation and representation were included in most cases, but there appeared less frequency in order of abductive reasoning, spatial thinking, and diachronic thinking. For observation, the ratio of purposive observation and autonomous observation is high. For representation, both visualizing and linguistic type of representation and free-form representation appear frequently. For abductive reasoning, the step of generating hypothesis is often included and the hypothesis tends to be about the geological formatting process. For spatial thinking, type of self-location and perception of the spatial configuration of the structure appear at a high rate. For diachronic thinking, type of stratigraphic sequence is the most frequent. The proportions of the cases including three or more elements of inquiry in field geology consist 87% of the total. We suggested implications for improving geological fieldwork as authentic science inquiry in the future.

In recent times, artists rely increasingly on science and technology, whereas scientists frequently use such an aesthetic tenn like 'eauty.' This shows that the gap between the 'two cultures' are narrowing down due to the necessity of both sides. The historical interaction between science and art has been extensively discussed by the historians of art and those of science. As the complexities of scientific and artistic practices were uncovered, similarities between them were also revealed. The goals of this paper, which explores the relationship and interactions between science and art, are the following three. The first is to bridge the gap between the two cultures (i.e., science and art) by disclosing the mutual influences between them. Second, drawing on recent works on the nature of scientific and artistic creativity, this paper aims to show some similarities and even common factors between scientific and artistic creativity. Finally, by highlighting similarities and common elements between scientific and artistic creativity, this paper will emphasize the role of imagination, insight, emotion and visualization not only in art but also in science.

According to the era, area, culture, and scholars, the beauty has been variously interpreted. This paper is analyzed about human beauty, the university environment beauty, and the relevance of awareness about beauty and convergence education. Especially this paper is researched on the basis of the survey data for the B University students. Also in this paper, we considered that what is beauty, whether and how to recognize human beauty, which was investigated whether the beauty of the campus environment. Futhermore, we discussed about relevance of beauty and convergence education. We describes relevance of major education and aesthetics, and relevance of characteristics education. In this survey, it can be seen that theses students have awareness of holistic human beauty and that inner beauty rather than outer beauty is more preferentially. The beauty of university environment is important to know university member's beauty, and individual character and major competencies of faculties and staffs suited to establishment ideology of the university, and the emotional education and administration suited to the emotional generations. Because beauty awareness of university programs appear through the students' character and major competence, it was recognized that the convergence beauty education of university program is properly carried out is important.

예측 기관에 따라서 B2B의 시장 규모 및 성장률에 대한 차이는 있지만 B2B 시장이 빠른 속도로 성장하고 있으며, 이 같은 추세는 계속될 것이라는 점에 대한 이견은 없는 편이다. B2B는 기업에게 비용 절감과 시간 절약, 업무 효율성 증대 등의 다양한 효과를 제공해 줄 수 있기 때문에 앞으로도 그 중요성은 더 커질 것으로 예상된다. 그러나 B2B의 중요성 및 성장세와는 별도로 아직까지 B2B에 참여하는 기업들이 큰 효과를 거두지 못하고 있는 것이 사실이다. 이에 따라 많은 학자들과 컨설팅 회사들이 B2B의 모형, 추진 전략, 성공 요인들을 다양한 각도에서 제시하고 있다. 하지만 B2B에 대한 실증적 연구가 부족하여, 기업의 실무자들이 실질적인 도움을 얻기에는 부족한 점이 있기 때문에 B2B의 성공 요인과 추진 전략에 대한 실증적 연구가 절실히 필요하다. 본 연구의 목적은 B2B 유형 중 가장 널리 활용되고 있는 MRO e-marketplace의 성공에 영향을 주는 요인들을 실증적으로 분석하는 것이다. MRO e-marketplace의 성공 요인을 환경적 특성, 제품 특성, B2B 사이트 특성 등 3 그룹으로 분류한 후, 38개 기업에서 수집된 설문지를 분석하여 MRO e-marketplace의 성공 요인을 실증적으로 분석하였다. MRO e-marketplace의 성공 요인들을 요인 분석한 결과, 기업 내부 환경 요인, 기업 외부 환경 요인, 제품 정보 요인, 제품 공급 능력 요인, 사이트 기본 기능 요인, 사이트 편의성 요인, 사이트 보안성 요인 등 총 8개 요인으로 분류되었다. 한편 MRO e-marketplace의 도입 효과를 측정한 비용 절감, 시간 절약, 업무 효율성 증대, 거래 투명성 증대 등의 4개의 문항은 하나의 요인으로 묶여, 이를 MRO e-marketplace 성공으로 정의하였다. MRO e-marketplace의 성공에 영향을 미치는 요인을 찾기 위해, 추출된 8개 요인과 MRO e-marketplace 성공 간의 상관 관계를 분석하였다. 8개 요인 중에서 기업 내부 환경 요인, 제품 공급 능력 요인, 사이트 기본 기능 요인이 MRO e-marketplace의 성공에 영향을 미치는 것으로 나타났다. 마지막으로 MRO e-marketplace 성공 요인들의 상대적 중요도를 파악하기 위해 회귀 분석을 실시하였는데, 참여 기업의 내부 환경 요인이 가장 큰 중요한 것으로 나타났고, 그 다음은 제품 공급 능력 요인과 사이트 기본 기능 요인으로 나타났다. 이 같은 실증적 결과는 MRO e-marketplace나 B2B의 성공을 위해서는 참여 기업의 내부 환경 조성이 매우 중요함을 시사해 준다. 또한 참여 기업의 제품 공급 능력 요인 역시 MRO e-marketplace의 성공에 직접적인 영향을 주기 때문에 공급기업들의 제품 공급 능력을 높이는데 노력해야 한다. 또한 MRO e-marketplace를 운영하는 기업들은 사이트의 기능을 높이는데 많은 노력을 기울여야 한다는 것을 시사하고 있다. MRO e-marketplace의 성공 요인을 실증적으로 분석한 본 연구의 결과는 MRO e-marketplace와 B2B의 추진 전략의 이론적 모형 개발에 유용하게 활용될 수 있을 것이다. 또한 본 연구의 결과는 MRO e-marketplace와 B2B의 성공을 높이기 위한 추진 전략을 수립하는데 유용하게 활용될 수 있을 것으로 기대된다.

Game theory is mathematical analysis developed to study involved in making decisions. In 1928, Von Neumann proved that every two-person, zero-sum game with finitely many pure strategies for each player is deterministic. As well, in the early 50's, Nash presented another concept as the basis for a generalization of Von Neumann's theorem. Another central achievement of game theory is the introduction of evolutionary game theory, by which agents can play optimal strategies in the absence of rationality. Not the rationality but through the process of Darwinian selection, a population of agents can evolve to an Evolutionary Stable Strategy (ESS) introduced by Maynard Smith. Keeping pace with these game theoretical studies, the first computer simulation of co-evolution was tried out by Hillis in 1991. Moreover, Kauffman proposed NK model to analyze co-evolutionary dynamics between different species. He showed how co-evolutionary phenomenon reaches static states and that these states are Nash equilibrium or ESS introduced in game theory. Since the studies about co-evolutionary phenomenon were started, however many other researchers have developed co-evolutionary algorithms, in this paper we propose Game theory based Co-Evolutionary Algorithm (GCEA) and confirm that this algorithm can be a solution of evolutionary problems by searching the ESS.To evaluate newly designed GCEA approach, we solve several test Multi-objective Optimization Problems (MOPs). From the results of these evaluations, we confirm that evolutionary game can be embodied by co-evolutionary algorithm and analyze optimization performance of GCEA by comparing experimental results using GCEA with the results using other evolutionary optimization algorithms.

The sudden emergence of China as a superpower in world politics and economics is apparently a big surprise. This, however, is not an unusual incident. As far as the Chinese are concerned, they say that China is simply running almost the same track that its neighboring countries. In the recent years, a number of experts and scholars have expected that the emergence of China as a great economic power will be argued as a major issue in world politics and economics. So its economic progress will require experts and scholars to watch carefully how China is going to change. It certainly has created an atmosphere that most of the world leaders, experts and scholars are very concerned about China's remarkable performance in its economics and then willing to accept China's rapid growth as an urgent matter. Many experts and scholars began to analyze carefully the factors that have contributed to the rapid growth. Foreign direct investment (FDI), import-export, and economic reform were then listed as the most important factors. As a result, philosophy of economics, analytical economics, and economics are immediately needed for China who is at the moment very anxious to sustain the stable and continuity of rapid economic growth. But unfortunately China does not even recognize the reason why they need to adopt these economic concepts and methods.

As whole genome sequences of many organisms have been revealed by small-scale genome projects, the intensive research on individual genes and their functions has been performed. However on-memory algorithms are inefficient to analysis of whole genome sequences, since the size of individual whole genome is from several million base pairs to hundreds billion base pairs. In order to effectively manipulate the huge sequence data, it is necessary to use the indexed data structure for external memory. In this paper, we introduce a workbench system for analysis and visualization of whole genome sequence using string B-tree that is suitable for analysis of huge data. This system consists of two parts : analysis query part and visualization part. Query system supports various transactions such as sequence search, k-occurrence, and k-mer analysis. Visualization system helps biological scientist to easily understand whole structure and specificity by many kinds of visualization such as whole genome sequence, annotation, CGR (Chaos Game Representation), k-mer, and RWP (Random Walk Plot). One can find the relations among organisms, predict the genes in a genome, and research on the function of junk DNA using our workbench.

This paper attempts to complement the methodological and conceptual lack of spatial thinking in Korean women's movement research and to facilitate further discussion on this field of research, by drawing on recent academic discussion on scale developed particularly among the Western critical and feminist geographers. The purposes of the paper are following. First, it addresses the need to utilize the concept of scale in women's movement research. Numerous spatial metaphors often proliferated with indiscretion in the feminist approach have rather tended to hinder fully understanding the spatiality of social movements. In order to examine the spatiality of social movements as both conceptual tool and praxis, not merely as metaphor, the paper incorporates main issues in recent scale discourses with particular attention to the debate between Marston and Brenner, and explores their implications for women's movement research in Korea. Second, it emphasizes the multi-scalar approach by highlighting the role of micro-scale, the less studied side in social movement literature. The public and the private divide, the long time battle ground in feminist research, is often intermingled with the hierarchical scalar understanding which considers the global as more powerful and important than the local. The reproductive realm, however, is indispensably related to production and political economic realm. The paper explores the very site where both the public/private divide and the hierarchical scalar understanding can be dismantled. It is the site where the private becomes public and the local becomes the global (and vice versa). Drawing on a brief example of an anti-FTA movement of women with strollers in Korea, it examines the way the multi-scalar approach advances the understanding of Korean women's movement.
