This paper analysis spatial correlation applying commercial activating factor and categories clusters among have homogeneity in garosu street which are rising commercial issue in residential district. Based on this research we can draw several implications. Firstly, Garosu street are forming unique space around fassion feature like clothes and food and Beverage stores are supporting main functions. secondly, in terms of utilization of semi-public space in individual buildings, main Street are using display goods and put product.Also restaurants and cafes are using public space as terrace seats. These results mean principal road emphasizes displaying and passing but inner road emphasizes taking a break and staying. Third, repetitive action between high rising vacancy and new building cause negative effects city decline and lossing identity. So residents and merchants should cooperate and make communities for sustainable district.

Modernism is understood as a process of differentiation. Postmodernism or postmodernity, by contrast, involves de-differentiation. There is a breakdown in the distinctiveness of each of spheres of social activities. It is important to explain an examination of the relationships between the de-differentiation and a wide variety of contemporary tourism, expecially postmodern tourism. Also, de-differentiation between the tourism and the social spheres lead to the spatial reflection. Aim of this paper is to examine the processes of de-differentiation between the tourism and the social spheres, which comes out spatially in Jeju island. Especially, location of destinations is concentrated on the coastline in the period of modem tourism. On the contrary, the postmodern tourism shows that the location of destinations are wide spread diffusion its vertically and horizontally. It means that there are to appear a breakdown of distinctiveness between the conventional tourism destinations and the regional person's space.

The communication system using multiple antennas improves link reliability or system capacity using tx & rx diversity, spatial multiplexing, and beamforming technique with services and characteristics of channel environment. This system is sensitive to spatial channel environment. In case of diversity, the lower correlation among links as a LoS environment, the better performance is acquired. In practical channel environment, However, there is high correlation, and there is high performance difference between ideal case and practical case. On the contrary, in case of beamforming, the higher correlation among links, the better performance is acquired. If we use the spatial adaptive transmission technique with spatial channel characteristics, we can get the system that maintains minimum link reliability and guarantees the overall system performance. In this paper, we propose the adaptive transmission and reception technique which use diversity or beamforming technique with channel characteristics.

절연파괴의 원인이 되는 절연체중의 공간전하의 여러 특성을 정량적으로 측정하였다. 전극에서의 주입전하가 트랩되어 주로 공간전하를 형성하는 것을 확인하였다. TSSP측정법으로 컬렉팅 전위를 결정하고 바이어스의 시간, 전압, 온도에 따른 공간전하 변화량을 측정하여 공간적 분포의 깊이를 조사하였다. 그리고 정상상태에 있어서 모델과 해석과 시험 결과가 비교적 잘 일치함을 발견하였다.

본 연구는 2017년 이후 문화복합공간에서 이루어진 무용 프로그램에 관한 연구로 국내를 중심으로 진행하였다. 국내의 복합문화 공간중에 문화비축기지, 문화역 서울284, 인천아트플랫폼에서 이루어지는 무용 프로그램으로는 무용공연, 레지던시 프로그램, 행사프로그램이 있었다. 문화복합공간은 무용가들에게 작업 공간을 제공하고 있으며 앞으로도 무용가들이 다양한 네트워크를 형성하고 창작 활동을 할 수 있는 가능성을 제공할 것이다.

When the character of space could be dichotomized into the existing public space and private space, social order could be maintained by public policing only, Since enormous private property was formed and private space was enlarged by the development of capitalism, however, the necessity of private policing system came to the front. The large capitalists began to establish separate policing system to protect their property and safety. However, as social alteration was further diversified scale of economy was enlarged, the character of space could not be simply explained owing to the formation of space that could not be explained by simple dichotomous division. Namely, the 3rd space was formed as middle class between public space and private space. The 3rd space created additional demand of policing besides the existing public policing and private policing. The policing system to safety such demand of policing is called hybrid policing. As policing system in which character and legal status of public policing and private policing are mixed, the hybrid policing system may be originated from the diversification of demand of policing. Johnston insists that the demand of hybrid policing system will be further increased, becoming the model of policing system in the future. In Korea, the police guard system or special guard system can be classified into the type of hybrid policing. In accordance with the trend of diversified demand of policing in the future, I suggest to develop Korean model of hybrid policing system so that it can be utilized in elevating the policing index in Korean society.

공간권은 3차원적으로 정의된 공간에 대한 지배권 또는 공간을 분할하여 공간의 일정범위를 공학적으로 이용하는 권리로 정의할 수 있다. 공간권은 입체적 토지이용을 촉진하는 제도적 수단이 될 뿐만 아니라 토지의 이용가치를 최대로 발휘할 수 있는 도구가 될 수 있을 것으로 판단된다. 그러기 위해서는 먼저 새로운 패러다임에 맞는 지적에 대한 법률관계의 형성, 공간권에 대한 정확한 개념정리 등이 필요하다. 현행 2차원 평면지적에서의 기본단위인 필지(筆地)도 공간상에 존재하는 토지에 대한 인위적이며 기하학적인 구획선으로 관리하고 있으므로, 토지를 기반으로 공간상에 존재하는 모든 객체를 3차원으로 정의하여 관리할 수 있으리라 판단된다. 본 연구는 우리나라에서 적용 가능한 3차원 지적모형을 찾기 위한 기본연구로 먼저, 공간권에 대한 개념을 정의한 후 공간권의 적용가능성에 대하여 법률적인 부분에서 심층적으로 검토하고, 궁극적으로는 3차원 지적의 도입을 위한 기반을 다지고자 한다.

This article aims to explain how Gangnam, as a model and standard of compressed urbanization in South Korea, was created. Gangnam and Gangnam-style urbanization need attention not only because they contrast with Korea's urbanization in the past as well as urbanization in the West but also they provide an important model in contemporary Korea's politics, economy and culture. However, there are little studies of how Gangnam's peculiar urbanism was created. To fill this gap, this article will first capture Gangnam's peculiar urbanism as a material landscape and sociocultural lifestyle. Gangnam-style urbanism is (a) materially characterized by high-rise apartment complexes owned by the middle and upper class for dwelling and asset growth and (b) socio-culturally characterized by political conservatism, public indifference, competition over academic performance, appearance, and fashion, and nightlife. Then it will show Gangnam's archetype was created in a spatially and temporally compressed way in and through the spatial selectivity of Korean anti-communist authoritarian developmental state strategies: (1) anti-communism led to the diffusion and accommodation of the population through apartments in Gangnam in the context of its confrontation with North Korea and the fast-growing population of Seoul; (2) military authoritarianism excluded the low-income class and the urban poor from urban development; and (3) the developmental state adopted selective housing policy which treated construction companies and the middle class preferentially through exceptional zoning and price distortions, promoting the construction of apartment in Gangnam and its resultant uneven development.

Lately, the improtance of smooth blasting is increasing on every construction fields, suchas underground caves, tunnels, and roadconstruction, etc. The main purpose of smooth blasting is to prevent unnecessary cracks from the base rockwhich preserved permanently and is to gain the smooth fracture plane. So, in smooth blashing, explosives with low detonating velocity are generally used. But it is difficult to discuss general theory on the smooth blashing because the mechanical properties of pertienent rocks are difficult regionally. Accordingly basic reserches on the smooth blasting are demended. In this paper, the mechanisms of the smooth blasting on the rocks containing discontinuities were discussd. Firstly, the writer predicted the formation of fracture plane and unevenness using mathematical methodology, the next the model blast tests were conducted in order to simulate the crack propagation modes from the blast holes. Through the research, the following conclusions were obtained l)The blast test results were in reasonally good agreement with the theoretical prediction. 2)The degree of discontinuity has an influence on the fracture morphology.
