This research was conducted on the conservation area of Baekdudaegan, Kangwondo under the purpose of evaluating bio-diversity according to the changes of spatial scale, using GIS data and spatial filtering method. The diversity index was calculated based on the information of species of The $5^{th}$ forest type map using Shannon-weaver index (H'), evenness index ($E_i$) and richness index ($R_i$). The diversity index was analyzed and compared according to the changes of 12 spatial scales from Kernel size $3{\times}3$ to $73{\times}73$ and basin unit. As for H' and $R_i$, spatial scale increased as diversity index decreased, while $E_i$ decreases gradually. H' and $R_i$ was highest; each 1.1 and 0.6, when the Kernel size was $73{\times}73$, while $E_i$ was 0.2, the lowest. When you look at according to the basin unit, for large basin unit, 'YeongDong' region shows higher diversity index than 'YeongSeo' region. For middle basin unit, 'Gangneung Namdaecheon' region, and for small basin unit, 'Gangneung Namdaecheon' and 'Gangneung Ohbongdaem' region shows high diversity index. When you look at the relationship between diversity index and Geographic factors, H' shows positive relation to curvature and sunshine factor while shows negative to elevation, slope, hillshade, and wetness index. Also $E_i$ was similar to the relationship between H' and Geographic factor. Meanwhile, $R_i$ shows positive relationship to curvature and sunshine factor, while negative to elevation, slope, hillshade, and wetness index. macro unit diversity index evaluation was possible through the GIS data and spatial filtering, and it can be a good source for local biosphere conservation policy making.

The purpose of the present study was to investigate the relationship between spatial ability and sex-role orientation in children. For this purpose, 303 boys and 293 girls were selected randomly. Spatial ability was measured by Embedded Figures Test. Sex-Role orientation was measured by the Children's Personal Attributes Questionnaire (Spence, Helmreich & Stapp, 1975) which was translated into Korean. An item analysis was done. For the data analysis, a three-way analysis of variance and t-test were applied. The results of the present study showed that 1) spatial ability gradually improved between 10 and 14 years of age. 2) There were no significant differences between girls and boys in the performance on the spatial ability test. 3) Masculinity in girls was not significantly associated with high spatial ability. However, there was a tendency for the masculine girls in the direction of higher spatial scores than feminine girls and undifferentiated girls. 4) Femininity in boys was not significantly associated with high spatial ability. However, there was a tendency for the feminine boys in the direction of higher spatial scores than masculine boys and undifferentiated boys.

This paper describes a new data-handing, based on a Spatial Human Interface as human indicator, to the Spatial-Knowledge-Tags (SKT) in the spatial memory the Spatial Human Interface (SHI) is a new system that enables us to facilitate human activity in a working environment. The SHI stores human activity data as knowledge and activity history of human into the Spatial Memory in a working environment as three-dimensional space where one acts, and loads them with the Spatial-Knowledge-Tags(SKT) by supporting the enhancement of human activity. To realize this, the purpose of SHI is to construct new relationship among human and distributed networks computers and sensors that is based on intuitive and simultaneous interactions. In this paper, the specified functions of SKT and the realization method of SKT are explained. The utility of SKT is demonstrated in designing a robot motion control.

Dengue Fever(DF) and Dengue haemorrhagic fever(DHF) has become a major international public health concern. Dengue Fever(DF) and Dengue haemorrhagic Fever (DHF) is also still the major health problem of Thailand, although many campaigns against it have been conducted throughout the country. GIS and Remotely Sensed data are used to evaluate the relationships between socio-spatial, environmental factors/indicators and the incidences of viral diseases. The aim of the study is to identify the spatial risk factors in Dengue and Dengue Haemorrhagic Fever in Sukhothai province, Thailand using statistical, spatial and GIS Modelling. Preliminary results demonstrated that physical factors derived from remotely sensed data could indicate variation in physical risk factors affecting DF and DHF. The present study emphasizes the potential of remotely sensed data and GIS in spatial factors affecting Dengue Risk Zone analysis. The relationship between land cover and the cases of incidence of DF and DHF by information value method revaluated that highest information value is obtained for Built-up area. A negative relationship was observed for the forest area. The relations between climate data and cases of incidence have shown high correlation with rainfall factors in rainy season but poor correlation with temperature and relative humidity. The present study explores the potential of remotely sensed data and GIS in spatial analysis of factors affecting Dengue epidemic, strong spatial analysis tools of GIS. The capabilities of GIS for analyst spatial factors influencing risk zone has made it possible to apply spatial statistical analysis in Disease risk zone.

A movement of visitor is a practical means that provides a spatial arrangement of exhibits and validity to that principle. Thus, an exhibition of a museum cannot be completed by an intrinsic value of exhibition itself. Thereby the purpose of this thesis is finding out the relationship between the visitors' pattern and spatial configuration in museum. As a result, as for the visitors' movement, it was grasped that diversified patterns of movements could appear in case the selections of courses are diversified within the environment in that the general understanding about the spaces was easy. That is, the exhibition environment in that general understanding about the spaces is easy because of the low depth of the exhibition space recognized from the entrance of the exhibition space and composition of exhibition space with diversified selections of courses may induce diversity of viewing patterns. That is, it may mean that in such composition of space, visitors may establish viewing courses based on their own purposes of viewing and preference thus they form individual spatial experiences themselves.

This paper will show examples and methods of spatial relationship operations that extract spatial information from satellite images. Geographical information system phenomena of complex and variant real world can abstract and implement simple features. The abstract features classify geo_objects and geo_field. The geo_object and the geo_field can represent vector and raster respectively. The raster based satellite image can use remote sensing applications. This paper needs topology operations and geometric operations for extracting the remote sensing. The spatial information transforms the raster based image to the vector based object, and extract from the spatial information. The extracted information will contribute on the application of the remote sensing satellite images.

As the span of spatial structure is getting longer, the law frequency of the structure makes the wind-induced response much increased. However, there are lots of hardships to establish the economical structural systems due to the fact that an relative equation between the frequency and the span of the domestic spatial structures is not existed in the stage of the basic planning design. Therefore, among the large-span structures, this paper focused on the relationship between the frequency and the span of the world-cup stadium built in 2000s. The relative equation between the frequency and span is compared with the data measured in Japan. Moreover, we are willing to provide the basic study by suggesting the summary equation in this paper.

With the modern society approaching, a lot of new paradigms have been created which can be explained by the existing space notions while suspicions on the true essence and existence of space have been raised. Ontology regards as the beginning the cause for a 'Field' which will be faced for the research of the essence of a space where 'being-in-the-world' exists. This study has analyzed the existing method of space construction in the spatial thinking and works of Peter Zumthor who mentioning ontological viewpoint as the physiological background of his works so that the ontological spatial concept may be clarified. The following is the study results. First, in order to construct the structures of his own designing into a 'Field' for experiencing the existential meaning, Zumthor chose a reductive pattern with the entire additional elements removed. The materials leading the subjects to call attention to memory and experience and the methods dealing with it enables the realization of various spatial essences. Second, the ontological event-system is required for the formation of relationship among beings. He tried to create a spatial meaning by introducing external environment into the inside and using the materials reflecting regional features and phenomenological empiricism through the multisensory experience. Third, he applied assimilation/insert/adjustment/formative change as the way of constructing the relationship between site and structure.

Spatial prediction methods have been useful to determine the variability of water quality in space and time due to difficulties in collecting spatial data across extensive spaces such as watershed. This study compares two kriging methods in predicting BOD concentration on the unmonitored sites in the Geum River Watershed and to assess its predictive performance by leave-one-out cross validation. This study has shown that cokriging method can make better predictions of BOD concentration than ordinary kriging method across the Geum River Watershed. Challenges for the application of cokriging on the spatial prediction of surface water quality involve the comparison of network-distance-based relationship and euclidean-distance-based relationship for the improvement in the predictive performance.

Due to the rapid development of computer and digital technologies, those technologies were used in advertising. In order to meet the needs of marketing, a virtual space or character using 3D graphic augmented reality technology was developed and applied to advertisement. This study analyzed the characteristics of augmented reality in terms of interface design and spatial expression of augmented reality through case study. Firstly, we wanted to find the relationship between the types of the augmented reality advertisement and interface effects. Secondly, we wanted to find the spatial expression methods. The sample survey case studies based on 42 articles from 2012 to 2018 using Chinese and Korean site sharing augmented reality advertisement. The results of the case studies were divided into two parts. Firstly, the relationship between augmented reality types and interface effects were found basing on the augmented reality index. It means that the augmented reality index can be illustrated by using the augmented reality type. Simultaneously, the augmented reality type can be illustrated using the interface effect. The second part was that the types of display were used as a spatial representation. And the results showed that mobile display and public place display were the most frequently used.
