Population is important as a fundamental element of local industry and economy, and census data is essential to regional planning and policy making. Although there have been many researches on population and regional planning, there are few studies on population considering spatial unit. In this study, the population of three spatial scales were compared in order to establish the spatial unit suitable for the rural planning. The study area is Gangwon, Chungcheong-Nam, Chungcheong-Buk, Jeolla-Nam, Jeolla-Buk, Gyeonsang-Nam, Gyeonsang-Buk and Jeju province. Population were compared using statistical data analysis, GIS visualization, and spatial statistics. The mean, maximum, minimum, and variance of population were calculated and the coefficient of variation according to spatial unit was compared. The mean, maximum, minimum, and variance of population were calculated and the coefficient of variation according to spatial unit was compared. As the results, the census output area unit is difficult to interpret spatial analysis results. Administrative district unit has the limit that includes areas where the population does not live. The grid unit is well suited to the geographical characteristics but has many disadvantages of the grid with small population. Therefore, It is necessary to complement the limits of the Eup and Myeon-dong administrative district through the grid unit data.

The present study focuses on the contribution of a teaching unit to the development of spatial ability of third graders in general and from a gender point of view in particular. The research population consisted of seventy-four pupils: thirty-seven pupils in the experimental group who attended the teaching unit and thirty-seven pupils in the control group. The spatial ability of all the pupils was examined by means of common tests which checked cognitive capabilities of spatial ability. The research findings illustrate an improvement in the spatial ability of the experimental group pupils following the participation in the teaching unit. Moreover, regarding the gender aspect, the findings show that there was no significant differentiation between the spatial ability of third grade boys and the spatial ability of girls of the same age group.

The purpose of the study is to identify a basic spatial unit for rural village redevelopment plan. An ideal spatial unit need to satisfy three basic premises: to be homogeneous as rural community, to be appropriate to implement the project, and to be compatible with regional planning systems. A spatial unit could, empirically, be defined based on the homogeneity at first, and then appropriateness and compatibility could be used to adjust its boundary. Mitan-Myun(13 villages), Pyungchang County, Dochuck-Myun(15 villages), Kwangju County, and Chuksan-Myun(28 villages), Kimje City in Korea were selected as case study areas. The degree of interrelationship between all possible pairs in each Myun was measured using spatial, socio-cultural, and economic indicators. Multidimensional Scaling(MDS) was used to identify a homogeneous spatial unit, and then indicators representing appropriateness and compatibility were used to adjust the identified boundary. New districts which have two or three villages were suggested as a reasonable spatial unit for rural village redevelopment, and its boundary roughly overlaps with Bup-Jeong-Ri(法定里: a legally defined village).

In the spatial configuration of a unit plan, two rules exist: one that governs the arrangement of spaces, and one that controls the design process of generating a unit plan. This study defines space grammar as an integration of the two rules that give birth to a given spatial configuration and as the process of the generation of unit plans. To understand the distinctive features of Indonesian row houses, this study analyzes the unit plans of row houses in new towns of the metropolitan cities of Indonesia, derives a common space grammar from the unit plans, and interprets the sociocultural background that has produced this space grammar. This study employs Seo's (2007a; 2007b) graph-theoretic methodology to analyze the spatial configurations of unit plans along with a topographical approach to systematically illustrate the design process. The guest space was found as the most unique space of Indonesian houses, which cannot be found in other Southeast Asian houses. Kitchen was clearly seperated from the dining and living spaces, following traditional custom. Dining space was found to serve as a circulation center, connecting the entrance, the lving area and the kitchen. This study locates the basic orders of primary space and the design principles that dictate the unique spatial configurations of Indonesian row houses. This study reveals the basic space grammar that underpins the forms of Indonesian row houses, explaining the sociocultural and geo-climatic factors affecting this space grammar and proposing unique characteristics of Indonesian contemporary houses.

A study on Composing Unit Spaces of Apartment Houses according to the Differentiation in Lifestyle by survey on preferences. The purpose of this study is to propose composition models of unit spaces for 85m2 net area apartment houses by lifestyle types. This study set up a hypothesis that there is a critical divergence of preferences in composition types of unit spaces according to lifestyle. To prove the hypothesis, investigation on variable floor plans of apartments to extract spatial composition types of units and questionnaire survey on lifestyleand preferences for composition types were implemented. To extract several factors regarding, characteristics of lifestyle, factor analysis, was implemented for each variable. Cluster analysis was conducted to cluster interviewees by similarity of lifestyle. To identify and define how each factor reacts, ANOVA and cross tabulation analysis between factors and clusters were used. The type of spatial composition was analyzed by plane characteristic, spatial relation and spatial usability on the basis of apartment plate type. As a result, lifestyle was divided into three types: reasonable lifestyle, trend-seeking lifestyle and conservative lifestyle. As, the result of investigating characteristics for the type of spatial composition according to the type of lifestyle, preferred types and main districts were different. Therefore, the hypothesis was proved.

This paper deals with the spatial configuration of the unit floor plan based on the apartment building type. It is generally agreed that various apartment building types were organized by diverse apartment unit floor plan. The reason behind this diversity, apartment unit plan are affected by the environmental condition and the diverse spatial composition of the unit floor plan. Apartment building types were classified by the similarity of the justified-graph type. This types classified into two category; One core type which were classified by the shape of the core, and multiple core type which were compounded by more than two core. These categories divided into 5 types, and 2 types. Each types were compared in view of the mean depth, relative asymmetry, integration value. Consequently, these types could be classified in the number of the unit floor plan. It is profitable to 3 unit types which was analyzed in view of an indicator of the spatial configuration. Therefore, 3 unit types is favorable to the composition of the apartment building types.

Spatial distribution analysis of industrial locations plays a very important role in the establishment of relevant spatial policies and plans. The first thing to consider in this analysis is what analysis indicators and spatial units are used, because the interpretation of the analysis results may vary depending on the analysis indicators and the spatial units. Therefore, this study first examines various industrial integration indicators considering spatial autocorrelation and suggests the classification of regional types of industrial aggregation through the combination of related indicators. And then, this paper aims to empirically analyze the root industry by presenting a methodology for analyzing industrial integration by various spatial units such as individual locations, grids, and administrative districts. The results of the empirical analysis show that the grid in the spatial unit can be analyzed in more detail than the administrative unit. In addition, it is expected to overcome the limitations such as differences in interpretation that may occur due to the setting of spatial units. In the classification of regional types, the south-eastern region of Ulsan, Busan, and Changwon, and the western region of the SMA of Incheon, Hwaseong, and Ansan were analyzed as the industrial cluster type.

With the change of family type and diversify of life style, residents need various unit plan in Quality. A rate of economically productive women has increased, and generally double-income households will continuously increase in the future. So a research is requested to consider the double-income households's satisfaction for a unit plan based on their life characteristics. The purpose of this study is to find out double-income households's lifestyles, and to search and analyze users' needs for spatial composition according to their lifestyles, and then, embody spatial composition of Apartment Unit plans. The findings are as follows. (1) Housing lifestyles of users living in apartment are categorized into 5 types: seeking the way to make housework easy and comfortable, making the best use spatial composition, pursing the universalism, housework oriented, pursing the leisure. (2) The type of seeking the way to make housework easy and comfortable requests facility with home appliances and a shower bath, the type of making the best use spatial composition requests storage space and trial about new plan, the type of pursing the universalism is concerned about the protection of environment and a memorial service, the type of housework oriented wants a talk with their family and discuss some problem, and the type of pursing the leisure requests division of household with their family and likes traveling and sports.

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.
