The purpose of this study is to clarify the global commodity chains of the grafted cactus of Umseong region. The major findings of this study are as follows. Buying materials for cultivating the grafted cactus is based on the intra-Umseong local network. In addition, exporting grafted cactus using cheaper labor force means spatial division of labor from semi-periphery region to core region in terms of Wallerstein's world system theory. It is thought that buyer-driven commodity chains of farm products profit by division of labor caused by a sales network of the grafted cactus. And such situation means that high quality of the grafted cactus in Umseong maintains the spatial continuity by commodity chains.

The purpose of this study is to explore the way in which the internet audience constitutes cyber culture by analysing a bulletin board system(BBS) on a historical drama, 'The World of Women'(SBS). Research findings show that the internee audience participates in a cyber space by five manners; personal participation(18.9%), critique of broadcaster's policy(11.3%), participation in a television drama community(42.1%), co-authorship(6.4%), evaluation and interpretation(21.3%). Through these kinds of participant activities, the internee audience tends to constitute a new cyber culture. Firstly, the audience seems to read 'The World of Women' by a specific way. It is the interest of a Um court lady that is characteristic on BBS of 'The World of Women'. Secondly, the internet audience constructs a new community of meaning by means of using emoticon(emotion and icon), deconstructing grammar, and remaking new signs. Thirdly, the internet audience argues their power over drama production, in other words, their ownership over the drama. Fouthly, the audience actively protests and criticise the policy of the broadcaster, especially charged service. Finally, the internet audience is likely to enjoy writing itself as a fun.

As the modern techniques have improved, people intend to store and manage the information on the web. Especially, it is the image data that is given a great deal of weight of the information because of the development of the scan and popularization of the digital camera and the cell-phone's camera. However, most image retrieval systems are still based on the text annotations while many images are creating everyday on the web. In this paper, we suggest the new approach for the semantic image retrieval using the RDF metadata based on the representation of the spatial relationships. For the semantic image retrieval, firstly we define the new vocabularies to represent the spatial relationships between the objects in the image. Secondly, we write the metadata about the image using RDF and new vocabularies. Finally. we could expect more correct result in our image retrieval system.

This Article studies a meaning of geometrical-mathematical spatial idea in the source of modern theories of space. Modern theories of space elucidated a relation of human and space through the geometrical terms; point, line, plane and extension etc. Descartes and Newton identified space as a natural realty, Leibniz and Kant elucidated space as a subjective idea or form. It is the result of modern spatial theories that space is lied nearly in human. In the meaning of natural space, space is empirically unfolded with a shape of measuring in front of human's eyes. In the meaning of cognitional space, space is a method or subjective cognitional form that human understands nature and constitutes world. Modern theories of space would be divided into four patterns. In Newton's theory space is absolutely prior to things. In Leibniz' theory space is a co-existence order of Monads. In Descartes's theory space is identified with extension. In Kant's theory space is cognitional form of subject. They all are confronted with each other in the source of space. In their confrontation they reflected on the relation of human and space in their own standpoint. We classify their particularly differential concepts of space into natural space and cognitional space. And then we analyze a difference of spatial meanings, and then investigate foundations of meaning of modern theories of space. On the one hand they are become to the source of alienation of human from space. But on the other they are contributed to get space familiar with human through a wakening for the correlation of human and space. The natural space indicates that with measurable shape space is extended really in front of human's experiential eyes. But the cognitional space elucidates that space is only a subjective idea or form with which human understands nature and constructs world. In the former it is embossed that space is independent to human, and is able to be measured and to be treated according to natural raws. In the latter it is evidenced that space is not separated to human, and that space is not without human, and a correlation existed between human and space. Humanist ideal is declared in them. It was a declaration of human sovereignty to nature. But this declaration is caused to alienate human beings from space.

Social historical geography is interested in geographical elements related with a social group and perceives the diverse dimensions of a geographical phenomenon. The purpose of this study is to examine and interpret the multi-layers of meanings associated with the ancestral places of lineage group, i.e. Bonkwans(本貫)in Korea with a viewpoint to social historical geography. The term Bonkwan does not appear in any historical records prior to ths 10th century. Thereafter it is used continuoushy by lineage groups or by govermment agents till the 17th century. I believe that during this long-term period Bonkwan assumed multiple geographical meanings which varied from period to period, such as residence place, a place of origin, and a place symbolizing power. Each layer of meaning was the product of a certain period and of a cetain lineage. Its first meaning was produced in the early Koryo kingdom. Its second meaning from late in the same kingdom to the early part of Chosun kingdom. In order to understand the meaning of Bonkwan correctively, we need to see it at a large perspective. That is to say, it needs to be viewed in the framework of immigration study of each lineage because the term is more is moreof a social construct than a fixed notion.

To investigate how personality test items are understood by participants, their semantic representations were explored by Latent Semantic Analysis, In this thesis, Semantic Similarity Matrix was proposed, which contains cosine similarity of semantic representations between test items and personality traits. The matrix was compared to traditional factor loading matrix. In preliminary study, semantic space was constructed from the passages describing the five traits, collected from 154 undergraduate participants. In study 1, positive correlation was observed between the factor loading matrix of Korean shorten BFI and its semantic similarity matrix. In study 2, short personality test was constructed from semantic similarity matrix, and observed that its factor loading matrix was positively correlated with the semantic similarity matrix as well. In conclusion, the results implies that the factor structure of personality test can be inferred from semantic similarity between the items and factors.

This study tries to study the poetic beauty of the space deconstructed by the medium appearing in Moon Sam-seok's children's poetry to help with simultaneous education and guiding methodology. The research method is based on the assumption that semiotics spatial image is read. In other words, we intend to derive the poetic beauty of the space in which the great pole space built by is deconstructed by the intervention of by the medium term . Among Moon Sam-seok's series of works, the research text is "The Wind and the Fire," "The Wind and the Empty Bottle," "The Wind and Salt," "The Wind and the Rock." According to the study, the wind deconstructed a space that was differentiated by the presence or absence of matter into a "coexistence space." These poetic spaces symbolize poetic beauty as ideal places of life that coexist in a distinction but not discrimination. Second, the wind has eliminated the gap between alienation, suffering and solitude. In other words, the wind deconstructed poetic space produced poetic beauty with the 'space of communication' based on homogeneity of the nature of existence. In conclusion, Moon's poetic speech can be seen that he intended to express the discreteness of the poetic space as 'communication' and 'common life' by deconstructing it with deviation and convergence by introducing a medium.

공간자료를 다루는 일반적인 과정은 연구자의 정의에 따라 달라질 수 있지만, 일반적으로 자료 수집, 자료 구축, 분석 및 결과 도출의 일반적인 과학/공학적 분석 절차와 유사하다. 산업체의 관점에서 볼 때, 1990년대 초기 국가GIS 사업이 시작될때부터 현재까지는 공인된 자료 구축에 많은 주안점을 두어서 기존 아날로그 자료의 디지털화, 자료 가공, 데이터베이스 구축, 자료의 시각화 등의 일반적인 자료 구축 및 도시에 주안점을 두어왔다. 또한 다양한 공간해상도의 원격탐사 자료와 같이 다중 근원 자료의 이용이 빈번해짐에 따라 공간자료의 갱신 또한 중요한 부분을 차지하고 있다. 그러나, 공간자료를 다루는 일련의 과정이 궁극적으로는 특정 분야에서의 의사 결정보조자료의 제공 등을 지향한다고 간주할 때, "from data to information to knowledge"의 중간 혹은 최종 단계의 결과물을 산출하기 위한 적절한 분석 기술의 개발 및 적용 또한 중요한 부분을 차지한다. 공간분석을 별도의 학문분야로 간주하느냐 아니냐의 문제와는 상관없이, 최근 20년간 공간분석은 GIS 및 원격탐사 분야뿐만 아니라 기본적으로 공간자료를 다루는 많은 응용분야에서 공간자료의 이해와 부가정보의 생산을 위한 중요한 기술 분야로 간주되어 왔다. 공간분석의 여러 응용 분야중에서 환경분야에의 적용 연구는 또한 환경과학이라는 별도의 분야 뿐만 아니라, 기존 학문들인 지리학, 생태학, 지구과학, 사회학, 경제학, 도시 계획 등의 하위분야에서 중요한 방법론으로 자리 잡고 있다. 이 기술 세미나에서는 환경분야에 직간접적으로 활용이 가능한 공간정보 분석 기술의 동향을 지구통계학을 중심으로 소개하고자 한다. 국내에서 크리깅으로 대표되어온 지구통계학은 적용하는 학문 분야에 따라 보다 넓은 의미를 가지는 공간 통계학이라는 용어로 사용되고 있지만, 보다 학문적/기술적 의미로 살펴보면 공간분석의 특화된 분야로 간주할 수 있다. 1950년대 알려진 광상의 위치 정보를 이용하여 은둔 광상의 위치를 추정하기 위해 기본 개념이 소개된 이후에 수학적으로 이론이 1960년대 정립된 지구통계학은 많은 발전을 이루어 현재 다양한 분야에서 적용되고 있다. 그러나 외국과 달리 국내에서는 크리깅을 고급 내삽 기법으로만 간주하여 단순 주제도 작성에 제한적으로 사용하고 있다. 이 기술 세미나에서는 특정 학문분야에서 적용되기 보다는 일반적으로 통용될 수 있는 지구통계학의 기본 개념을 우선 소개한 후에, 국내외 학계에서의 환경주제도 제작과 관련된 주요 응용분야를 소개하고자 한다. 이후에 지구통계학이 적용될 수 있으면서, 다학제적 관점에서의 이슈가 될 수 있는 분야를 제시하고자 한다.
