This paper aims to clarify physical characteristic of empty house and vacant floor in historic district on Cheongju. First, most empty houses are the timbered houses of 1 story, and it will be built before the 1969. And the building of a vacant floor has a common non-residential buildings of 4 stories, and there are many buildings of RC structure built in the 1980s. Second, when the situation of an empty house and a vacant floor was seen, there was most the second floor only by the number of room, but when seen from the ratio of the whole number of rooms, there were most the third floor and the fourth floor. Third, when the situation of a vacant floor and a vacant room was seen from use, there were most store, shop and office. Relevance with this as close as reduction of the population in the center of Cheongju is seen. Moreover, the grope of a method which can utilize this is required.

The purpose of this study is to investigate the effect of floor area ratio incentive system for Long-life housing certification system by simulation of five recently built apartment complexes. Apartments that are certified as superior in Long-life housing can receive 10% of the floor are incentive in Seoul. However, the difference between base and permitted floor area ratio are in general residential area of class 2 and 3 is not more than 20%. limit of feasible allowance incentive is limited. Even if there is an unrealized permitted floor area ratio, there is no reason to apply the Long-life housing certification system preferentially. Because the items of the floor area ratio incentive provided by the District Unit Plan are various, it shows that the floor space ratio incentive for Long-life housing certification system has little effectiveness. To enhance the feasibility of incentives for the Long-life housing certification system, improvement in the urban planning level, including district unit planning, including the design criteria for apartments in Seoul, is needed.

Effort to reduce energy consumptions or CO2 emissions is global trend. To follow this trend, spatial studies related to characteristics affecting energy consumptions or CO2 emissions have been conducted, but only with the focus on spatial dependence, not on spatial heterogeneity. The aim of this study is to investigate spatial heterogeneity patterns of CO2 emission based on socio-economic factors, land-use characteristics and traffic infrastructure of Seoul city. Geographically Weighted Regression (GWR) analysis was performed with 423 administrative district data in Seoul. The results suggest that population and employment densities, road density and railway length in most districts are found to have positive impact on the CO2 emissions. Residential and green area densities also have the highest positive impact on CO2 emissions in most districts of Gangnam-gu. The resulting model can be used to identify the spatial patterns of CO2 emissions at district level in Seoul. Eventually it can contribute to local energy policy and planning of metropolitan area.

Along with the rapid development of the economy, the urban scale has extended rapidly, leading to the formation of different types of urban function districts (UFDs), such as central business, residential and industrial districts. Recognizing the spatial distributions of these districts is of great significance to manage the evolving role of urban planning and further help in developing reliable urban planning programs. In this paper, we propose an automatic UFD division method based on big data analysis of point of interest (POI) data. Considering that the distribution of POI data is unbalanced in a geographic space, a dichotomy-based data retrieval method was used to improve the efficiency of the data crawling process. Further, a POI spatial feature analysis method based on the mean shift algorithm is proposed, where data points with similar attributive characteristics are clustered to form the function districts. The proposed method was thoroughly tested in an actual urban case scenario and the results show its superior performance. Further, the suitability of fit to practical situations reaches 88.4%, demonstrating a reasonable UFD division result.

In 2018, the Cultural Heritage Administration of Korea introduced a new system that registers national cultural heritage in street and district units. Yeongju City's Modern Historical and Cultural District was selected as the first trial region. This grouping method breaks through conservation and utilization limitations of cultural heritage in individual building units. Thus, the issue is how will such historical and cultural spaces be grouped, conserved and managed. Hence, this study identifies the current situation of buildings in the Modern Historical and Cultural Street of Yeongju and conducts an experimental survey. Based on this, the types of modern architecture were classified, and the architectural groups were extracted and categorized to preserve and utilize the architecture. For these purposes, priority groups were determined by evaluating them based on five criteria: archetype, placeness, politicalness, typicality and originality. The modern architecture in the Modern Historical and Cultural Street of Yeongju have undergone many changes. The residential transformation of small and medium-sized cities during modern times can be understood as a process of settlement and nativization.

The study aims to identify the degree and types of spatial decline in Eup/Myun units within Chungcheong region in South Korea to contribute to the efforts being made to diagnose the rural decline and the potentials. To this end, we analyzed 27 Sis and Guns to identify the degree of decline and potentials of rural areas in Chungcheong region. We also carried out the diagnosis and K-Means Clustering on 274 Eups and Myuns, the smallest administrative units, to figure out the types and characteristics of the rural recessions. According to the results of the clustering analysis carried out on the 166 Eups and Myuns, there were five outstanding clusters. They were; areas with housing deterioration (29), areas with poor economic foundation (16), areas with poor accessibility to central areas (42), areas with poor residential environment (51) and areas with aged population (28). The findings and results of the present study are likely to serve as a basis for the design and enforcement of forthcoming rural area activation policies. Also, it would be highly recommended that a more comprehensive diagnosis is taken from a community-level perspective and policy suggestions and strategies tailored for rural communities are further discussed.

Landmarks like high-rise building are one of the important elements for the enhancement of city identity and provides the hierarchy of city streets, playing a central and symbolic role in cities. Research on physical attribute of landmarks, such as height, distance, location and shape, which are suitable for a city scale, can help a city create a distinct image and maintain comprehensible structure. To achieve this purpose, it is necessary to understand the spatial and cognitive characteristics of a landmark for the establishment and management of it. The results of this study can be summarized as follows: 1. The level of representativeness of a landmark increases in proportion to the degree of cognitive intensity on it. The relation between representativeness and cognitive intensity can be explained as the log-function as follows: Log(the number of people who respond "It has representativeness")=$-1.2579+1.5908{\times}$(cognitive intensity); 2. There are a few differences based on the attributes of respondents: while gender has no distinct influence, residential period and age show statistically meaningful influence on cognitive intensity of a vertical landmark Cognitive intensity of an individual landmarks especially, differs according to the class of main users. Because of frequent changes in occupation or employment, respondents consider the distance from a residential area more important than the distance from a working area in evaluating cognitive intensity of landmarks; 3. landmark can be classified into two kinds: a district landmark and an urban landmark A district landmark is closely connected with physical attributes of the landmark itself, such as distance, size and height. An urban landmark is mainly related to cognitive attributes such as the image and identity of a city as a whole. As a result, the landmark analysis data in this research provides spatial order and identity in a city. It is difficult to establish and reinforce the image of a city as a single element ike a landmark. However, withy steady follow-up research, this study could be seen as a systematic and logical model to improve urban landscape and image.
