To address unsolved issues of change detection in animated choropleth maps, we proposed the concept of 'gross change detection' and performed an experiment that empirically verifies the incidence of change blindness stems from the 'magnitude of change (MOC)', spatial distribution in animated choropleth maps. We generated experimental materials using the change-characterization arrays and the global Moran's I. Participants had 108 cases of changing maps with time duration (1 to 3 sec) and had questions. The results showed that MOC and duration affect gross change detection, but the most interesting result from our experiment was that different spatial distributions between two adjacent choropleth maps may lead the map reader to under- or over-estimate the level of gross change in the map. It implies that we should consider spatial distribution of change when we design animated choropleth maps.

The characteristics of neighborhood correlation images for change detection were explored at different spatial resolution scales. Bi-temporal QuickBird datasets of Las Vegas, NV were used for the high spatial resolution image analysis, while bi-temporal Landsat $TM/ETM^{+}$ datasets of Suwon, South Korea were used for the mid spatial resolution analysis. The neighborhood correlation images consisting of three variables (correlation, slope, and intercept) were evaluated and compared between the two scales for change detection. The neighborhood correlation images created using the Landsat datasets resulted in somewhat different patterns from those using the QuickBird high spatial resolution imagery due to several reasons such as the impact of mixed pixels. Then, automated binary change detection was also performed using the single and multiple neighborhood correlation image variables for both spatial resolution image scales.

이 연구는 대학도서관 공간변화 동향 및 사서들의 인식조사를 기초로 대학도서관 공간변화의 방향성을 제안하기 위한 것이다. 이를 위해 2000년부터 2020년까지 대학도서관 공간변화의 특징을 분석하고 설문조사를 통해 공간변화의 문제점을 파악하였다. 조사결과, 지난 20년간 전국 대학도서관에서 총 99건의 신·증축 및 리모델링이 있었고, 최근 대학의 예산 긴축정책에 따라 신·증축보다 리모델링에 치중하는 것으로 나타났다. 공간변화의 특징으로는 이용자들의 요구 수용, 이용자 수 증대를 목적으로 도서관 내 휴게공간 확장과 쾌적하고 안락한 분위기 추구, 혁신적·창의적인 공간 설치 지향 등이 나타났다. 공간변화의 장점은 다양한 공간의 제공과 도서관 방문자 수 증가 등이며, 시설유지비 증가와 관리 인력 부족 등이 문제점으로 조사되었다. 또한 공간변화가 시대적 트렌드만 반영하고 서비스 및 대학도서관의 실질적 가치에 변화가 크지 않은 점, 획일성과 특징 상실 등이 지적되었다. 향후 대학도서관 공간변화는 대학도서관만의 차별성 확보와 다양한 변화에 대한 수용성, 대학도서관의 가치와 존재를 증명할 수 있는 상징성을 지향할 필요가 있는 것으로 분석되었다.

University is very big scale among urban facilities as for single facilities and there is characteristic that accompany various university support functions in contiguity area. Width that have diverse spatial configuration generally our country university campus around was formed, this does function that connect university and ambit. Specially, formation enables change of spatial configuration that existent width system has if is new around university campus. Also, can form more animate and lively width spatial configuration by forming more various and complex width spatial configuration in width had formed in existing. It is that search special quality of university surrounding width spatial configuration analyzing existing width spatial configuration of Kangwon National University back gate by formation if this study is new in city and forecasts the change, and used space syntax by spatial configuration analysis method.

The purpose of this study is to investigate the conceptions about altitude of the Sun of elementary students according to differences by the spatial ability. In this study through the qualitative analysis, 4 students who were similar understanding levels of concepts to altitude of the Sun and differences by the spatial ability were selected out of 75 in 6th grade elementary located in Sunchang, Jellabuk-do Province. 4 students for the qualitative analysis were selected by the test instrument of spatial ability and altitude of the Sun. The results of study was students with higher spatial ability were higher understanding levels of concepts to altitude of the Sun. However, both of student with higher and lower spatial ability showed a false concept to the expanded concepts into outer space like a cause of seasonal change, change of altitude of the Sun by latitude unlike the intution. Students with lower spatial ability didn't form the scientific concepts, not only a cause of seasonal change and change of altitude of the Sun but also difference of energy density by altitude of the Sun. A student of two with lower spatial ability has been impediment strongly to form the scientific concept by the false concepts to the distance. The findings were as follows; Learning to altitude of the Sun regardless of the difference of spatial ability should be learned to interact to the intution, celestial movement and model experiment. To students with lower spatial ability should be developed teaching methods to understand the relation between the Sun and celestial movement.

본 연구는 2D 기반의 동적 공간모형(dynamic spatial landscape models)을 통해 지표 변화 과정을 이해하고 예측할 수 있는 방법론을 제시하는데 그 초점을 두고 있다. 동적 공간모형 에 기반한 연구는 크게 지표의 공간 패턴에 대한 모형화와 변화 과정에 관한 모형화 및 모의로 구성되어 있는데 지표 변화와 관련된 규칙은 변화 원인과 그 과정에 따라 다르게 정의될 수 있다. 이때 지표 패턴의 이질성은 변화와 밀접한 관계를 가지고 있기 때문에 연구 지역의 GIS 맵으로부터 공간 패턴의 특성을 모형화 하여 이를 기반으로 변화에 관한 동적 공간 모형이 적용되어야 한다. 본 논문에서는 이를 위한 모형기반 접근법이 설명되어 있고 자연 화재로 인한 지표 변화 과정에 적용되어 동적 공간 모형이 개발되었다.

The purpose of this study is to analyze the spatial characteristics of business-type-changed parcel in the Hongik-University commercial area, from the view point of commercial gentrification. A commercial gentrification occurs through a business-type-change in a spatial basic unit (microscopic spatial unit such as parcel) of an area which has not been considered in relavent policies and research. So, this study analyzed the spatial characteristics of business-type-changed parcels using the Cox's proportional hazard regression model. The main results of this study are as follows. First, as new developments in the adjacent area occur, the business-type-change probability increases. Second, by the commercial area division, the business-type-change probability is different. Finally, the accessibility is better, the probability is higher. These results could suggest that a consideration of the spatial characteristics form microscopic viewpoint is necessary to understand the commercial gentrification. And these could be used as basic data for a gentrification diagnostic and management system, which can predict gentrification from the view point of business-type-change on the basis of a parcel.

Since the terrain of Korea is complex, micro- as well as meso-climate variability is extreme by locations in Korea. In particular, air temperature of agricultural fields is influenced by topographic features of the surroundings making accurate interpolation of regional meteorological data from point-measured data. This study was carried out to compare spatial interpolation methods to estimate air temperature in agricultural fields surrounded by rugged terrains in South Korea. Four spatial interpolation methods including Inverse Distance Weighting (IDW), Spline, Ordinary Kriging (with the temperature lapse rate) and Cokriging were tested to estimate monthly air temperature of unobserved stations. Monthly measured data sets (minimum and maximum air temperature) from 588 automatic weather system(AWS) locations in South Korea were used to generate the gridded air temperature surface. As the result, temperature lapse rate improved accuracy of all of interpolation methods, especially, spline showed the lowest RMSE of spatial interpolation methods in both maximum and minimum air temperature estimation.

Change detection technology, which discovers the change information on the surface of the earth by comparing and analyzing multi-temporal satellite images, can be usefully applied to the various fields, such as environmental inspection, urban planning, forest policy, updating of geographical information and the military usage. In this paper, we introduce a change detection system that can extract and analyze change elements from high-resolution satellite imagery as well as low- or middle-resolution satellite imagery. The developed system provides not only 7 pixelbased methods that can be used to detect change from low- or middle-resolution satellite images but also a float window concept that can be used in manual change detection from highresolution satellite images. This system enables fast access to the very large image, because it is constituted by OGC grid coverage components. Also new change detection algorithms can be easily added into this system if once they are made into grid coverage components.
