It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.

This study investigates the utilities of spatial analysis in the context of survey research using Geographical Information System(GIS) and Geographically Weighted Regression (GWR) which take account of spatial heterogeneity. Many social phenomena involve spatial dimension, and with the development of GIS, GPS receiver, and online location-based services, spatial information can be collected and utilized more easily, and thus application of spatial analysis in the survey research is getting easier. The traditional OLS regression models which assume independence of observations and homoscedasticity of errors cannot handle spatial dependence problem. GWR is a spatial analysis technique which utilizes spatial information as well as attribute information, and estimated using geographically weighted function under the assumption that spatially close cases are more related than distant cases. Residential survey data from a Primary Autonomous District are used to estimate a model of public service satisfaction. The findings show that GWR handles the problem of spatial auto-correlation and increases goodness-of-fit of model. Visualization of spatial variance of effects of the independent variables using GIS allows us to investigate effects and relationships of those variables more closely and extensively. Furthermore, GIS and GWR analyses provide us a more effective way of identifying locations where the effect of variable is exceptionally low or high, and thus finding policy implications for social development.

This study examined the arrangement attribute of each component based on the relationship among the components using space syntax at the entire complex level when analyzing the outdoor space of an apartment complex in Cheonan and as a preliminary study. The accessibility change in the access space to each space and to the facilities were examined based on a resident walking in the perspective that the outdoor spaces of the apartment complex are one spatial structure connected together. The space was divided into a total of 5 periods and the access space to the facilities and spaces located in outdoor space of the apartment complex were established as the unit space. In this study, a total of 6 analysis items were established: main complex access space, main building access space, shopping mall within complex, control office/center for senior citizens, children's playground, and resident sports facilities. In the analysis, the following conclusion was obtained. First, the accessibility to the main complex access space was high over almost all periods and the main building access space generally showed low accessibility. Second, the shopping mall showed a tendency that the closer the period, the more the accessibility is increased. Third, the control office/center for senior citizens, which can be considered as a common resident space and the children's playground out of the resident sports facilities, showed an exceptional tendency, the integration order was constantly high without a large change by the period and the control office/center for senior citizens showed the tendency for a high integration order, indicating that it is planned mainly in a location with good accessibility.

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.

영국과 같은 서구 복지국가들은 최근 공공복지분야에서 많은 변화를 경험하고 있다. 특히 ‘신관리주의’에 근거한 ‘자치위임(devolution)’은 변화하는 복지국가의 중요한 특징 중의 하나이다. 영국에서 자치위임은 교육분야에서 가장 잘 진행되고 있다. 1988년의 교육법 개정 이후 영국의 초등학교들은 이전에 가지지 못했던 자치권을 지역관할교육청(LEA)으로부터 위임받았다. 특히 LEA로 부터의 학교재정에 관한 자치위임은 매우 중요하게 인식되고 있다. 지리적인 관점에서 이와 같은 공공복지분야에서의 변화들이 공간적으로 불균등하게 진행되고 있다는 점을 인식하는 것은 매우 중요하며 ‘자치위임’의 공간적 특성도 예외는 아니다. 본 연구를 통하여 영국 남부 사우스햄톤시의 초등학교의 자치위임은 지역적으로 매우 불균등하게 진행되고 있다는 것을 알 수 있으며 특히 이러한 불균등한 진행은 지역의 사회경제적 특성에 의해 크게 영향받고 있는 것으로 나타났다.

인터넷의 빠른 확산과 정보기술 패러다임의 변화로 사용자가 다양한 종류의 온라인 매체를 이용하여 콘텐츠 및 커뮤니티 제작 등에 능동적으로 참여하고, 이를 공유하는 양상이 사회 전반적으로 확대되고 있다. 이는 국가계획수립 부문에서도 예외는 아니어서 계획 주체와 국민간의 교류를 증진시키기 위해 등장한 개방형 계획패러다임과 맞물려 다양한 분야에서 PPGIS(Public Participation GIS)를 구현하기 위한 사업이 추진 중이다. 그러나 이러한 방법은 국가 주도의 단방향적인 참여기회 제공으로 단순한 의견수렴 수준에 머물고 있어 국민의 의견과 수요가 충분히 계획에 반영되지 못하며, 특정 계획분야에 국한되어 있는 실정이다. 그러므로 제공수단과 참여대상을 확대할 수 있도록 지리정보를 활용한 국민참여 기회를 제공하고, 이러한 결과가 GIS 활용분야 의사결정 과정에 적용될 수 있는 국가차원의 기반 마련이 요구된다. 따라서 이 연구는 정보기술 패러다임의 변화를 반영하여 사용자가 지리정보를 수단으로 자유롭게 의사를 개진하고, 정부가 이를 반영하여 계획을 수립할 수 있는 통합형 PPGIS 모델을 통한 G2C 상호작용 제고방안을 마련하고자 한다.

Job shop manufacturing environments are using the concept of cellular manufacturing systems(CMS) which has several advantages in reducing production lead times, setup times, work-in-process, etc. Utilizing the similarities between cell-machine, part-machine, and the shape/size of parts, CMS can group machines and parts resulting in improved efficiency of this system. However, when grouping machines and parts in machine cells, there inevitably occurs exceptional elements(EEs), which can not operate in the same machine cell. Minimizing these EEs in CMS is a critical point that improving production efficiency. Constraints in machine duplication cost, machining process technology, machining capability, and factory space limitations are main problems that prevent achiving the goal of maintaining an ideal CMS environment. This paper presents an algorithm that minimizes EEs under the constraints of machine duplication cost and factory space limitation. Developing exceptional operation similarity(EOS) by cell-machine incidence matrix and part-machine incidence matrix, it brings the machine cells that operate the parts or not. A mathematical model to minimize machine duplication is developed by EOS, followed by a heuristic algorithm in order to reflect dynamic situation resulting from minimizing exceptional elements process and the mathematical model. A numerical example is provided to illustrate the algorithm.

Tuff specimens were thermally treated with predetermined temperatures of 200, 400 and $600^{\circ}C$ to construct specimens simulating weathered tuff rocks. Specific gravity, absorption ratio, elastic wave velocity, uniaxial compressive strength, Brazilian tensile strength, Young's modulus, Poisson's ratio and slake-durability index were measured for pre-heated specimens. Heating of rock specimens entailed the degradation of material properties except for slake-durability index. It was found that correlations among P-wave velocity, uniaxial compressive strength, Brazilian tensile strength, Young's modulus and absorption ratio are high. Regression equations which use the P-wave velocity as an independent variable were presented to evaluate uniaxial compressive strength, Brazilian tensile strength, Young's modulus and absorption ratio.

Nowadays, urbanized area expands its boundary, and distribution of urbanized area is gradually transformed into more complicated pattern. In Korea, SMA(Seoul Metropolitan Area) has outstanding urbanized area since 1960. But it is ambiguous whether urban distribution is clustered or dispersed. That is to say, it is difficult to understand spatial distribution pattern of urbanized area, although urbanized area has grown gradually. This study aims to show the way in which expansions of urbanized area impact on spatial distribution pattern of urbanized area. We use GIS analysis based on raster dataset, quadrat analysis, and nearest neighbor analysis to know distribution pattern of urbanized area in time-series urban growth. Experiments show that cohesion of SMA's urbanized area had increased to the early 1980s, but has decreased from the middle 1980s. Also, urban growth of SMA has been characterized not by spillover growth but by leapfrogging growth and road-influenced growth since the middle 1980s.

The study ooramed has the meanngs as a goal, to examine a character and changes of function a "Maru" in the literatures historically. Methodically the literatures in the temporal oonsequences were selected, and the "Maru", whidl oomes into it, was interpreted in its historical oonnections. By the investigation I oould oome to the following results. First of all, those terms "Maru" and "Daechll1Q" were cfifferently used after the sizes and p1ares of the spaces concerned. I.e, the "Maru" in the center of the house is called "Daed1ung", With the Maru does not concern actually its p1are, Secondly, the functions of the spare "Maru" are characterized as follows. ·Space for the important ceremonies ·Spare for the passage and the switching of two or several spaces. ·Determination of the hierardly of spares in the whole house. ·Spare for the receipt. ·Spare for sleeping and for living. ·Spare for work, storage etc. Thirdly, the meanings of the "Maru" were dlanged as follows in the time. ·The term "Man! was used from the past to today without interrujjion. Arot.l1d 1930 the tenns "Yangsil" and "Geosil" for the tenn "Maru" were emerged. ·The different dlaraderistics for the space "Maru" are found in the cortemporary literatures only rare. This thing explains itself by the fad that the "Maru" becomes the inner-spare after 1900 by the restructuring of the dwelling spares.hing explains itself by the fad that the "Maru" becomes the inner-spare after 1900 by the restructuring of the dwelling spares.
