Spatial outliers in remotely sensed imagery represent observed quantities showing unusual values compared to their neighbor pixel values. There have been various methods to detect the spatial outliers based on spatial autocorrelations in statistics and data mining. These methods may be applied in detecting forest fire pixels in the MODIS imageries from NASA's AQUA satellite. This is because the forest fire detection can be referred to as finding spatial outliers using spatial variation of brightness temperature. In this paper, we propose a new forest fire detection algorithm which is based on local spatial association analysis, and test the proposed algorithm to evaluate its applicability. In order to evaluate the proposed algorithm, the results were compared with the MODIS fire product provided by the NASA MODIS Science Team, which showed the possibility of the proposed algorithm in detecting the fire pixels.

The purpose of this paper is to examine the characteristics of organic relations according to the characteristics of space and place in which human activities are spreading. The diffusion of various human experiences and the interaction of space and place that form a mutual construction network create momentum for expanding individual or collective experiences. The space and place that lead to the interactions of human activities are expressed in various ways. Through the domestic travel program especially, the ways of expressing space and place are spreading as various "fields of experience." The composition and the expression system of a travel program is transformed into a subject of thought, not a mere experience of space and place through the formation of a "field of experience" that can be thought out and thought of as an existing travel style. Therefore, in this study, we examine the characteristics of the MBC Plus channel from a socio-cultural perspective, expressed through the experience of space and place characteristics expressed through a travel program. The result of an analysis of story development composition for this study shows that the experience of space and place minimizes the boundaries of various cultural discounts according to their relationships to food and communication. In addition, the analysis results of a three-way communication structure show that the emotional code of the audience is maximized through the process of maximizing the effect of reality, and minimizing the gap between the cultural differences and the boundaries through the empathic situation and the empathic subject.

유기발광소자의 제작 기술이 빠르게 발전함에 따라 디스플레이와 조명 분야에서 많은 응용 가능성을 보여주고 있다. 유기발광소자의 발광효율은 발광층내에서 전자와 정공의 비와 밀접한 관계가 있기 때문에 전자 수송층과 정공 수송층내에서 전하의 이동도를 제어하는 구조에 대한 연구는 매우 중요하다. 본 연구에서는 전자 수송층으로 tris(8-hydroxyquinoline)aluminum ($Alq_3$)와 4,7-diphenyl-1,10-phenanthroline (BPhen)의 다중 이종구조를 사용하여 제작된 녹색 유기발광소자의 전기적 성질과 광학적 성질을 연구하였다. $Alq_3$와 BPhen 다중 이종구조의 위치와 이종구조 개수의 변화에 따라 전자의 변하는 전송특성으로 인하여 변화되는 발광특성을 체계적으로 조사하였다. 유기발광소자의 구동전압은 $Alq_3$/BPhen 이종구조의 수가 증가할수록 증가하는 경향을 보인다. $Alq_3$와 BPhen 내에서 전자의 이동도가 다르기 때문에 $Alq_3$/BPhen 이종계면에 전자가 축적되어 공간전하를 형성하므로 계면에서 내부전계가 형성되어 구동전압이 약간 증가하는 경향을 보인다. 또한 $Alq_3$/BPhen 이종계면에서 축적된 전자들로 인하여 형성된 내부 전계로 인해 저전압에서 누설 정공의 수가 증가하였다. 그러나 다중 이종구조로 된 전자 수송층을 포함한 유기발광소자의 발광 효율은 구동전압이 증가할수록 안정화 되었다. 이는 이종계면의 수가 증가함에 따라 각각의 이종계면에서 축적되는 전자의 양이 감소하기 때문에 고전압에서 효율감소율이 작아졌다. $Alq_3$/BPhen 다중 이종구조를 가진 전자 수송층내에서 전자의 전송 메카니즘에 대한 이해는 유기발광소자의 발광효율이 안정화된 구조를 설계하는데 중요한 실험적 결과를 제공한다.

This study was conducted under the judgement that there was a need to make several mentions by reference to studies about the spatial composition of the traditional village. The judgement was not about the dimension that there was a problem about the spatial composition of the existing village but that it would be effective to make a fresh reorganization of it in a little more detail. As a result, this study presented seven spaces in the spatial composition of the traditional village. It attempted to analyze it by dividing it into four spaces such as ① natural space, ② residential space and work space, ③ moving space and boundary space and ④ play space and ritual space to fit its basic nature. First of all, it made a pictorial presentation of the basic form of the spatial composition of the traditional farming village in the late Joseon Dynasty which was most general and whose form has been handed down up to the present. And it described the composition of each space accordingly. It was not intended for a specific village. So it presented the historical change, the behavior of the members surrounding the village and a difference according to the nature of the village, which were judged to be very important in explaining the items of the composition of each space. As a result, it was found that the spatial composition of the traditiona Korean village well embodied the framework of their life in terms of their view of nature, lifestyle and worldview. The view of nature acted on the spatial composition of the village as a whole and is well reflected in the natural space in particular. Their lifestyle is reflected in the residential space, farming space, moving space and play space, and their worldview is spcifically mirrored in the boundary space and ritual space. In particular, this study focused on how to take a look at the element of Feng-Shui in discussing the spatial composition of the village.

The ocean is a unique space for exchange with the city, forming an organic relationship between people and waterfront areas. The marine healing industry improves quality of life through medical care and well-being, and creates added value by combining with the medical industry. The policy analysis results are as follows. First, the marine healing industry is the newest high-growth area. Furthermore, a professional medical service hospital is the first priority. This will include the development of marine healing facilities and strengthening forest healing connectivity, emphasizing the development of highly specialized medical technologies. The second priority is value creation in marine healing specialization, accompanied by an integrated and systematic policy for research and development of new medicines in marine healing effects. It is also important to apply new market trends and develop applied marine healing service programs. Thirdly, it is necessary to explore the possibility of a fragmented market for policy development.

General development basis of letter system is recognized by formative value in terms of its function and structure. principle of clustered writing is the most significant feature of Hangeul typography as considered that it is based on function and formativeness. Thus, not only by changes with its form but also by its characteristic syllable combination, space structure is made as consonants and vowels are combined in single letter, then the combination develop into word, sentence, paragraph to make second, third space structure character. This character has significant impact on readability that is core function of typography. With this property, space structure character is regarded as very important component of Hangeul typography. First, space structure character of Hangeul typography is reviewed by relating it to visual perception of gestalt psychology and compared square-framed letter and framed latter By applying square-framed letter and framed latter in same sentence, legibility and readability were studied. Researcher has found that space structure character of Hangeul typography has significant impact on its function, and in terms of future design, it is very critical not only for design but also for communication environment as space structure formativeness of Hangeul typography interact with communication that is basic concept.

For multivariate datasets with large number of variables, classical dimensional reduction methods such as principal component analysis may not be effective for data visualization. The underlying reason is that the dimensionality of the space of variables is often larger than two or three, while the visualization to the human eye is most effective with two or three dimensions. This paper proposes a working procedure which first partitions the variables into several "latent" clusters, explores individual data subsets, and finally integrates findings. We use R pakacage "ClustOfVar" for partitioning variables around latent dimensions and the principal component biplot method to visualize within-cluster patterns. Additionally, we use the technique for embedding supplementary variables to figure out the relationships between within-cluster variables and outside variables.

국내 도시는 1960년대이후의 산업화에 따라 인구와 산업이 도시로 집중되어 급속하고 거대한 성장을 이루었고 대기오염 현상의 다양화, 복합화로 인해 스모그와 시정장애 등 새로운 오염현상이 심각해지고 있다. 도시지역 대기중의 오염물질 농도수준은 오염 배출원의 분포 및 배출강도 그리고 지역의 지형, 기상 요인 등 많은 요인에 따라 좌우된다. 특히, 대도시는 경제ㆍ사회ㆍ문화 등 다양한 요소들이 복합적으로 상호 작용하는 유기체적인 공간으로 특정 지역에로의 집중과 분산이 일어나면서 다양한 공간구조(예; 신시가지, 산업단지 등)를 만들어 가고(이광국 등) 이런 변화에 따라 대기오염의 공간적 분포 경향 역시 달라져 갈 것이다.

This thesis aims to study the space concept of the constructive mode in the work space of the postmodernism artists since 1970s. According to the changing view of the world artists, they are searching for the characteristics of having the parameter of formative organization on how they are related to the constructive system which represents the work styles. First, this study searches for the theoretical approaches of the constructive system and parameters that were studied by Le Corbusier - the module concept as the meaning of order system being used for the basic formative construction Second, when it is regarded as a formative construction in making art as the'principles of organization'(the law of living form), which was defined by Suzanne Langer in the formative theory as the organized structure shown in growth structure in mu and ecological system, the principles governing the module rules were arthmetically analysed art-work space through the dynamic symmetry of Jay Hambidge. Therefore, this study shows the principles working on the parameters for new formative organization as follows: First, the module in the work space should be designed and built from the dynamic symmetry. Second, the module should satisfy the human needs that it must be acceptable, efficient, flexible, which are the necessary and sufficient condition for the dynamic symmetry. Third, the dynamic symmetry which has the principle of Reciprocity and the principle of Complement as its primary construction principle has the common properties and the reciprocity in the construction of the work space and when it has the self similarity, it segments organically the total space without damaging the continuum.
