"China's Western Development Policy" has brought multiple opportunities to the development of tourism in Southwest China including Sichuan, Guizhou, Yunnan, Chongqing and Tibet. The 4 provinces and 1 municipality overall show a certain degree of accumulation effect and coordinated development in tourism due to their location, traffic and traditional economic cooperation. This study takes the Southwest China as the research object and utilized the spatial dislocation model and the tourism spatial misalignment index to estimate the mismatch degree between tourism resources and tourism income among provinces and try to find out the internal reason background. The results show that each of the five provinces has its own advantages in index of economy, tourism resources, human resource, and transportation, leading to differences in the center of gravity of the entire region in all aspects. In view of the results of spatial dislocation analysis, suggestions for improvement and optimization are put forward to promote the high-quality development of tourism in Southwest region. development.

This study has a purpose that definitize correlationship of spatial structure and sales strategies in mixed-use complexes which established in Korea since year 2000. For this purpose, this study tries to analysis spatial structure of mixed-use facilities through space syntax theory and makes an typological categorization based on their space composition. As a result of categorization, Korean mixed-use facilities can be classed as three types. First type is integrated stacking type. Second one is parallel connecting type. Third type is room to room type. According to differences between categories, their spatial structures show different meaning with different sales strategies. Integrated stacking type sales luxury brands and expensive stuffs and it also has deep and complicated structure. That means theses spaces usually make a strategy of exclusion. Parallel connecting type sales special categories and it also has shallow and easy spatial structure. That means these facilities want to make a smooth connection between apposed volumes. Room to room type sales cheap and fancy objects and it also has simple and shallow structure. That means simple spatial structure can be lead contact customer to stuffs. These results mean spatial structure have a effect on design of sales space.

Background: Spatial structure of plants in a population reflects complex interactions of ecological and evolutionary processes. For dioecious plants, differences in reproduction cost between sexes and sizes might affect their spatial distribution. Abiotic heterogeneity may also affect adaptation activities, and result in a unique spatial structure of the population. Thus, we examined sex- and size-related spatial distributions of old-growth forest of dioecious tree Torreya nucifera in extremely heterogeneous Gotjawal terrain of Jeju Island, South Korea. Methods: We generated a database of location, sex, and size (DBH) of T. nucifera trees for each quadrat ($160{\times}300m$) in each of the three sites previously defined (quadrat A, B, C in Site I, II, and III, respectively). T. nucifera trees were categorized into eight groups based on sex (males vs. females), size (small vs. large trees), and sex by size (small vs. large males, and small vs. large females) for spatial point pattern analysis. Univariate and bivariate spatial analyses were conducted. Results: Univariate spatial analysis showed that spatial patterns of T. nucifera trees differed among the three quadrats. In quadrat A, individual trees showed random distribution at all scales regardless of sex and size groups. When assessing univariate patterns for sex by size groups in quadrat B, small males and small females were distributed randomly at all scales whereas large males and large females were clumped. All groups in quadrat C were clustered at short distances but the pattern changed as distance was increased. Bivariate spatial analyses testing the association between sex and size groups showed that spatial segregation occurred only in quadrat C. Males and females were spatially independent at all scales. However, after controlling for size, males and females were spatially separated. Conclusions: Diverse spatial patterns of T. nucifera trees across the three sites within the Torreya Forest imply that adaptive explanations are not sufficient for understanding spatial structure in this old-growth forest. If so, the role of Gotjawal terrain in terms of creating extremely diverse microhabitats and subsequently stochastic processes of survival and mortality of trees, both of which ultimately determine spatial patterns, needs to be further examined.

본 연구에서는 공과대학 신입생(수학능력 시험에서 수학 B형을 친 학생들)들과 공학전공을 희망하는 자율전공 학생(수학 A형을 친 경우)들의 공간능력을 조사하여 수학 성취도와 공간능력 사이의 상관관계를 성별로 조사하였다. 그리고 문제해결전략에 성별로 차이가 있는지, 전략 선택의 차이가 공간능력에 실제로 영향을 미치는지를 확인해보고자 하였다. 이를 위하여 검사도구로 Purdue 공간 시각화 검사-회전(이하 PSVT-R)을 사용하였다. 또한 문항별 정답률을 성별로 구하고 분석해보았다. 연구결과, 공간 시각화능력-회전 능력에서의 성별 차이는 일반 공대생과 자율전공 학생들 모두 공통적으로 나타났고, 두 집단 모두 남학생이 여학생보다 10% 정도 우월 하였다. 검사에 참여한 학생들을 네 집단(일반 공대 남학생, 일반 공대 여학생, 자율전공 남학생, 자율전공 여학생)으로 나누었을 때 공간 시각화 능력은 일반 공대 남학생의 점수가 25점으로 가장 높았고, 다음이 자율전공 남학생(22.5)과 일반 공대 여학생(22.4)이 거의 비슷하였으며, 자율전공 여학생(19.2)의 순서로 낮아졌다. 공간 시각화 능력과 수학 성취도 사이의 상관계수는 동일한 집단 내에서는 모두 0.25이하로 둘 사이의 상관관계는 미미하였다. 그렇지만 집단 간에는 차이가 존재하는데, 일반 공대 및 자율전공 모두 남학생의 수학성취도와 공간 시각화 능력이 여학생보다 높았고, 수학 심화과정을 배운 일반 공대남(여)학생의 공간 시각화 점수가 그렇지 못한 자율전공 남(여)학생보다 높았다. 이 사실들은 공간능력과 수학 성취도 사이에 상관관계가 있음을 시사한다. 도형의 회전에서 문제해결 전략은 크게는 전인적(holistic) 전략부터 분석적(비교, 대조) 전략으로 나눌 수 있다. Mann-Whitney U 검증 결과 전략의 선택에서 유의미한 성별차이가 존재하였다. 그 외에도 일반 공대 남학생들에서는 전인적 전략을 80% 이상 사용했다는 응답이 가장 높았고, 일반 공대 여학생과 자율전공 학생들에서는 남녀 모두 전인적 전략을 50~80% 정도 사용하면서 비교, 대조와 같은 분석적인 방법을 곁들였다는 응답이 가장 높았다. 전략의 선택이 공간 시각화 능력의 점수 차이로 연결된다는 증거는 찾지 못하였지만, 만점을 받은 일반 공대생 집단은 남녀 모두 평균적인 선택보다는 전인적인 전략을 가장 많이 사용하였다. 한편 자율전공 하위권 학생들은 상대적으로 한 가지 전략에 치우치는 경향이 있었다. 따라서 도형의 회전과제에서는 두 가지 전략을 융통성 있게 사용하는 것이 문제해결에서 한 가지 전략만 과도하게 사용하는 경우보다 효과적으로 판명되었다. 마지막으로 문항별 정답률을 분석하여 여학생들의 정답률이 상대적으로 낮은 문항들을 추출하였다. 이 문항들의 특징은 회전축이 2개인 경우들에 집중되었다. 하지만 PSVT-R 점수의 차이는 효율적인 전략의 선택과 운영 외에도 주어진 도형에 대한 심적 이미지를 정확하게 만드는 능력에도 달려있음을 문항 분석 결과로 알 수 있었다. 위의 연구결과를 토대로 공간 시각화-회전 점수가 낮은 하위권 학생들에게 지금까지 그들에게 익숙하지 않았던 다른 전략을 학습할 경험과 기회를 제공할 것을 제안한다. 또한 문항 분석의 결과를 이용하여 정답률이 낮은 문항과 유사한 문항들을 개발하여 학습한다면 하위권 및 여학생들의 공간 시각화능력 향상에 도움이 될 것으로 기대한다.

In order to revitalize rural areas fundamentally through multifunctional utilization of their resources, it should be necessary to prepare the rational development plan to the areal characteristics and conditions, and the first priority of its planning works should be given to spatial planning. The space syntax method, a powerful objective and quantitative analysis tool on the relationship between social and spatial characteristics, was introduced in this study. Five Comprehensive Rural Clustered Villages Development Areas in the Jeonnam-province were selected as case study areas, of which total area's and included villages' spatial variables were measured and analyzed. Rural villages analyzed in this study have the spatial structure badly systematized and much complicated, which results from low integration and deep spatial depth of them. And, by virtue of relatively many axial lines, there should be few differences between villages in terms of local integration, connectivity and control, while being significant difference in terms of global integration showing the whole areal characteristics. Intelligibility, the correlation coefficient between connectivity(local variable) and integration(global one) is low, which means that the spatial structure of the study areas is difficult for visitors to understand the area or village well. Spatial configuration analysis results in the case study areas showed that each development area has a unique spatial structure and is differentiated in terms of not only local spatial variables but also global spatial variables. Therefore, global and local characteristics should be considered in spatial analysis of development areas.

공간 객체를 분할하는 비용이 크기 때문에, 기존의 객체 분할 기법들은 공간 조인 도중에 동적으로 객체를 분할하지 않는다. 본 논문은 객체 분할을 고려하지 않은 기존의 PBSM(Partition Based Spatial Merge-Join)에 적용될 수 있는 수정된 객체 분할 기법을 제시한다. 실세계 데이타의 한가지 특성은 객체들의 크기가 큰 차이를 보인다는 것이다. 본 논문에서는 이러한 특성을 바탕으로 전체 비용에 큰 영향을 미치는 적은 수의 큰 객체들만을 대상으로 분할을 적용한다. 이러한 수정된 객체 분할 기법은 공간 조인 도중에 큰 부담이 되었던 객체의 분할 비용을 크게 줄이면서 효율적인 여과 정제 단계를 수행한다. 여러 가지 실험 결과, 제안된 방법을 사용한 PBSM은 기존의 PBSM보다 월등히 향상된 성능을 보인다.

Urbanization has led to a reduction in green spaces and thus transformed the spatial pattern of urban land use. An increase in air temperature directly affects forest vegetation, phenology, and biodiversity in urban areas. In this paper, we analyze the changing land use patterns and urban heat distribution (UHD) in Seoul on the basis of a spatial assessment. It is necessary to monitor and assess the functions of green spaces in order to understand the changes in the green space. In addition, we estimated the influence of green space on urban temperature using Landsat 7 Enhanced Thematic Mapper Plus (ETM+) imagery and climatic data. Results of the assessment showed that UHD differences cause differences in temperature variation and the spatial extent of temperature reducing effects due to urban green space. The ratio of urban heat area to green space cooling area increases rapidly with increasing distance from a green space boundary. This shows that urban green space plays an important role for mitigating urban heating in central areas. This study demonstrated the importance of green space by characterizing the spatiotemporal variations in temperature associated with urban green spaces.
