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.

This research was conducted for the analysis the middle-old aged empty nest households' debt holdings and their financial status(emergency fund index, liquidity index, debt burden index) considering the level of income and assets. In order to accomplish this study, we made use of the KReIS third beta-version data. The results of the analysis were as follows. First, in all income asset groups there were more non-debts holding houses compared to debt holding houses. Moreover in debts holding houses, compared to other groups high income high assets groups were more. Second, the households that possessed more assets, had more debts. Third, the financial status of the households holding debts were more vulnerable compared to households that had no debts. Moreover, all income asset groups' emergency fund index were low. Households having no debts possessed low real assets and so the liquidity index was higher in holding debts households. In holding debts households, debt burden index was high. And especially these houses suffered from high debt burden when their income and asset were low.

The purpose of this study is to derive a model of urban regeneration business using idle facilities in the old city center. The scope of the study was set as empty houses and empty stores owned by private companies, and analyzed the 50 central city revitalization projects using idle facilities in 14 local cities in Japan. The results of this study are follows; First, as an urban regeneration strategy using idle facilities in the old town, it was a combination of other functions centering on commercial functions or introducing new functions required in the city center. Second, various financial supports have been provided to induce the utilization of idle facilities by the private sector, and different strategies have been implemented for businesses that need maintenance first. Third, based on the analysis results, it was possible to derive urban regeneration business model. Fourth, in order to operate smooth business, it is a need for an organization that is in charge of reviewing the consistency of upper-level planning and urban guiding functions such as urban revitalization plan, balance review of expenditure and revenues by cost subsidy and loan repayment, consultation among the business partners.

A electrical fault that may generate an electrical disaster is defined as any abnormal condition caused by reduction in the insulation strength. To find out the abnormal condition, periodical inspections have being performed every 3 years. Recently, the number of empty houses during normal working hours is rising by dramatic increase in the number of nuclear families and double income families. To define the potential risk of the electric installation, measurement of zero phase current has been being considered. But the measured value could not be adapted to an absolute reference to the installation because the measured zero phase current value also contained capacitive leakage current. Therefore, in this paper, the correlation between the condition of the electrical installation and the zero phase current was analyzed. The result focuses on to detect them in a cost efficient way.

In the historical and cultural blocks with the most concentrated urban cultural heritage, the development of both side streets is impacted by the development of the main street, which shows a gradual decline. The loss of placeness on both side streets has resulted in more empty houses. Therefore, it is urgent to pay attention and take countermeasures to the empty houses in historical and cultural blocks. In this study, the vacant houses on Zhongshan Road in Hangzhou, China were taken as the object of study to understand the location theory and the six dimensions of Matthew Carmona's urban design. Meanwhile, it further analyzed the evaluative features of the placeness of the vacant houses in the historical and cultural street, to provide direction and basis for the flexible using of other empty houses in Zhongshan Road. Then by applying the Analytic Hierarchy Process (AHP), it obtained the importance scale of each evaluative feature and compared the evaluation results of experts with the analysis results of cases, getting the results as follows: In the flexible application of vacant houses in historical and cultural street, the evaluation result of placeness indicates that this kind of usage should be in order of societal level, perceptional level, functional level, morphological level, visual hierarchy and temporal level; among the evaluative features, security, identity, usability, individuality, aesthetics, connection, diversity, openness, continuity, accessibility, order and history should be considered in turn.

Many houses have been left vacant in cities worldwide due to changes in the economy, society, and urban composition. The increase in vacant houses causes social problems and decrease in the value of real estate. Considering the cost of preparing a new residence because the existing residence no longer functions, it is an important problem to solve empty houses in the existing residence. Accordingly, policy attempts and studies to reduce and utilize vacant houses are in progress in various countries. In South Korea, the ratio of vacant houses was 6.4% of all houses as of 2021, and in Jeolla-buk-do, it was 11.6%, which is higher than the national average. Jeollabuk-do conducted a fact-finding survey on countermeasures against vacant houses; 17,732 vacant houses (2.4%) were surveyed. The urbanization, population, and terrain of Jeollabuk-do, consisting of 14 cities and counties, were considered. The ratios, types, grades, and spatial autocorrelations of vacant houses were analyzed after classification into city areas (focus, small, and medium) and county areas (plains and mountains) areas to derive policies according to the distribution of vacant houses. The average difference in ratio, type, grade, and spatial autocorrelation of vacant houses was used to analyze the characteristics of the distribution of vacant houses according to these classifications. There were significant differences in the averages of the ratios, grades, and spatial autocorrelations between city and county areas. The autocorrelation of vacant house distribution exhibited differences between urban and county areas.

The number of empty houses during normal working hours is rising. As a result, the number of uninspected electric installations for general use is increasing. To define the potential risk of the electric installation, measurement of leakage current has been getting considered but because the measured leakage current value also contained leakage current by capacitance, the measured value can not be adapted to absolute reference to the installation. Therefore in this paper, the correlation between the condition of electric installation and leakage current were analyzed.

Abandoned empty houses are largely left neglected as unused space, due to the slowdown in the real estate market that has resulted from the declination of urban functions. This research aims to analyze the characteristics of the City of Detroit's policies and regeneration efforts regarding abandoned houses, based on the perspective of unused space. This is expected to provide the baseline data for similar efforts to be applied to abandoned houses in the Korean context, thus preventing the decline of urbanism by adopting relevant policies and regeneration efforts. Some of the key features of the City of Detroit's regeneration efforts are: 1) the active participation of residents and open-data policies, 2) the diversification of regeneration strategies depending on the potential of the unused space, and 3) securing differential plurality of the regeneration processes.

Nagaya is one of the traditional Japanese housing types in which multiple houses are attached together. In Nagaya, walls are shared by several houses but entrances are privately owned by houses. Nagaya consists of many wooden houses for common people located in parallel with narrow alleys between them. Nagaya was one of the representative housing types in Japanese architectural history. This research is to study the background of the origination of Nagaya in Japan, the characteristics of space and land planning, the features and causes of the changes in the space and land planning. In this research, we observed and analyzed unit plans of a block of gate-type Nagayas in Hanan, Osaka. The results are as follows. First, as the inner alleys(Roji) are closed, the number of entrances to each housing lot decreased from two to one since one entrance that used to be open to inner alleys(Roji) are permanently closed. Second, walls between streets and housing lots which used to be one of the outstanding characteristics of gate-type Nagayas are disappearing. Third, as the bathrooms are added to houses, the front gardens are being degraded to empty spaces or sometimes totally removed. Fourth, the space in the first floor of houses become family spaces, and that in the second floor is divided into private rooms for individuals.

An electrical fault is defined as any abnormal condition caused by reduction in the insulation strength between energized conduction parts and ground or any grounded part of an electrical system. Failure of solid insulation can be caused by excessive mechanical tension being applied on the insulation, harsh service environment, aging, and also by corona phenomena. The number of empty houses during normal working hours is rising. As a result, the number of uninspected electric installation for general use is increasing. To define the potential risk of the electric installation, measurement of leakage current has been getting considered, but because the measured leakage current value also contained leakage current by capacitance, the measured value can not be adapted to absolute reference to the installation. Therefore, in this paper, the correlation between the condition of electric installation and leakage current were analyzed.
