This study is about occurrence pattern of vacant spaces as a urban decline indicator to consider a decline of old hillside residential area from spatial structure perspective. For investigation based upon vacant space and the street structure, this study selects Ami Chojang-dong in Seo-gu, Busan, of which 79.7% of total area is over a gradient of $10^{\circ}$. Focused on relationship between occurrence pattern of vacant spaces and 'vertical alleys(link)' serving as main movement path of local residents in hillside residential area, the length, numbers, slopes, and use characteristic of vertical alleys were analyzed using Arc GIS 9.3 program to classify characteristic zone types of spacial structure in hillside residential area. After the occurrence pattern of vacant space are interpreted in relation with building density, vertical alleys' number length slope, the social and economic issues have been considered as well. After analyzing the occurrence pattern of vacant space, this study argues that the occurrence pattern of vacant space in old hillside residential area is rather affected by street structure system consisting of vertical alleys than the impacts of social economical issues.

This research was undertaken to compare basic bodice prototypes for Internet shopping customer, and to select a profitable fit vacant space quantity between clothing and body. A total one hundred of eighteen outfits (4 types of pattern ${\times}$ 9 subjects ${\times}$5 body areas) were constructed with basic bodice drafting method of Japan Bunka Women's University according to nine male body types. Fifty-two experts analysis of the different prototypes as five body area and evaluate the most appropriate ease amount and stabilization of the simulation images on the computer. The experiments with automated methods using simulation image are based on AZ program of TORAY, Japan. Data was analyzed using percentiles, frequency and $X^2$. Taken together, the present result of vacant space quantity and stability evaluation through images shows that there is a significant difference in the size variation of the chest circumference, shoulder slope and waist circumference. In case of ease amount, chest area, shoulder slope, waist area and armhole except neckline area were shown more appropriate on the basic bodice pattern without size change. In case of stabilization, the chest area, shoulder slope and armhole except waist area and neckline area was shown the best on the basic bodice pattern without size change. However the waist area was shown on the basic bodice pattern plus 2 cm, neckline was shown more appropriate on the basic bodice pattern plus 1cm.

Urban problems are constantly occurring around the world due to rapid industrialization and population decline. In particular, as the number of vacant houses is gradually increasing as the population decreases, it is necessary to prepare countermeasures. A plan to utilize vacant houses has emerged to restore the natural environment of the urban ecosystem where forest destruction, damage to habitats of wild animals and plants, and disconnection have occurred due to large-scale development. Through connectivity analysis, it is possible to understand the overall ecosystem flow based on the movement of species and predict the effect when vacant houses are converted into green spaces. Therefore, this study analyzed the green area network to confirm the possibility of greening of vacant houses neglected in Jeonju based on circuit theory. Using Circuitscape and Least-cost path, we tried to identify the connectivity of green areas and propose an ecological axis based on the analysis. In order to apply the resistance values required for analysis based on previous studies, the 2020 subdivision land cover data were integrated into the major classification evaluation items. When the eight forests in the target site were analyzed as the standard, the overall connectivity and connectivity between forests in the area were high, so it is judged that the existing green areas can perform various functions, such as species movement and provision of habitats. Based on the results of the connectivity analysis, the importance of vacant houses was calculated and the top 20 vacant houses were identified, and it was confirmed that the higher the ranking, the more positive the degree of landscape connectivity was when converted to green areas. In addition, it was confirmed that the results of analyzing the least-cost path based on the resistance values such as connectivity analysis and the existing conceptual map showed some differences when comparing the ecological axes in the form. As a result of checking the vacant houses corresponding to the relevant axis based on the width standards of the main and sub-green areas, a total of 30 vacant houses were included in the 200m width and 6 vacant houses in the 80m width. It is judged that the conversion of vacant houses to green space can contribute to biodiversity conservation as well as connectivity between habitats of species as it is coupled with improved green space connectivity. In addition, it is expected to help solve the problem of vacant houses in the future by showing the possibility of using vacant houses.

Vacant houses are increasing across the country, but the appropriate measures have not been set up yet. Accordingly, vacant houses are left unattended for a long time, and become deserted to degrade the residential environment. They are often used as the space for the deviation of youth or even for crimes, threatening the safety of rural society. Vacant houses are not only personal properties but also public assets that form the residential environment of a town. Therefore, the problem should be better taken care of with appropriate policies. In this study, the present situation of vacant houses in Korea, the causes of the vacant house and the limits and lessons of the improvement projects were reviewed, along with the vacant house improvement systems in the UK and Japan. The most significant difference between the cases in Korea and other countries are the method of vacant house improvement. In terms of policies and support, Korea focuses on demolition, whereas other countries focus on reuse. In addition, the vacant house improvement projects in Korea are performed mostly by government agencies, whereas local governments and private organizations in other countries cooperate to improve vacant houses and go beyond mere residential environment improvement towards the local revitalization. Based on the study results, the following are proposed to efficiently improve and use the rural vacant houses. First, the Rearrangement of Agricultural and Fishing Villages Act, which allows the vacant houses to be left unattended and not improved, should be revised. Second, the intermediate support organizations that connect the demand and supply should be fostered and supported so that the use of vacant houses can be vitalized and privately led. Third, the best practices of using the vacant houses should be found and promoted, and the vacant house remodeling technique should be developed and propagated. Fourth, a special law should be enacted to comprehensively plan, support and execute the vacant house improvement, as in Japan. Finally, the value of the vacant houses as public properties should be shared in public so that all citizens can participate in addressing the vacant house issue to derive the detailed plans to solve the problem.

우리나라는 2000년대 이후 급속한 경제성장 시대를 지나 보다 안정된 경제성장 시대에 접어들면서 국토와 도시의 발전형태도 변화하고 있다. 대규모 신개발의 필요성은 점차 감소하는 가운데 도시 외곽에서 파편화된 소규모 개발이 진행되는 한편, 기존 도시 내에서 유휴화 되는 공간이 증가하고 있다. 따라서 기존 도시의 압축적 이용을 위해 이러한 유휴공간에 대한 효율적 이용이 필요한 실정이다. 그러나 이를 위해서는 무엇보다 도시내부에 존재하는 다양한 유휴공간을 체계적으로 파악하고 관리할 수 있는 과학적 방법과 수단이 필요하다. 본 연구는 이와 같은 배경 하에 다음과 같은 목적을 가지고 수행하였다. 첫째, 유휴공간을 체계적으로 파악하기 위한 분석모형을 실험개발하고 부산시를 대상으로 실증연구를 수행하고자 한다. 둘째, 오픈소스 GIS 소프트웨어인 uDig을 활용하여 유휴공간 분석시스템을 실험 구축하고자 한다. 공간적 문제의 파악과 해결을 지원하기 위해 GIS기반의 공간의사결정지원체계나 계획지원체계를 구축하여 활용하는 것은 새로운 시도는 아니다. 그러나 최근 발전하고 있는 오픈소스 GIS를 활용할 경우 기존의 독점적 소프트웨어를 사용하는 것과는 차별화된 장점이 있다. 본 연구는 상기와 같은 내용을 기반으로 향후 국토도시에 존재하는 유휴공간을 체계적으로 파악하고 활용하기 위한 오픈소스 기반의 계획지원체계를 구축하는데 필요한 시사점을 제시하였다.

A zero-shrinkage sintering process in which the shrinkage of x-y axis is controlled to be zero is in great demand due to the trend of high integration in the ceramic modules. Among the zero-shrinkage sintering processes that are available, the proposed glass infiltration method where the viscous but fluidic glass infiltrates of the $Al_2O_3$ particles in the structure of $Al_2O_3$/glass/$Al_2O_3$ during firing is one of the applicable methods. However, the above proposed glass infiltration method has the problem of the warpage-like delamination. This occurred at the outermost surface of the multiple-bundle substrate. It is thought that the decomposed gas rapidly expands in low viscous glass to create vacant space. To solve this problem, the vacant space was tamped with $Al_2O_3$ particles to lead to the actual improvement of the sintered properties. With 15 wt% of tamping $Al_2O_3$ particles in glass, most of the vacant space disappeared. Fully densified zero-shrinkage substrate without delamination can be obtained.

Rural spaces are increasingly valuable as areas for introducing renewable energy infrastructure to achieve carbon neutrality. Rural areas are the living grounds of rural residents, and the balance of conservation and development for rural areas is important for the introduction of reasonable facilities. In order to maintain a balance between development and preservation and to introduce reasonable renewable energy facilities, it is necessary to develop a current status survey and an effective survey method to utilize a space capable of introducing renewable energy facilities such as idle land and vacant houses. Therefore, this study was conducted to verify the readability using an unmanned aerial vehicle, and the main results are as follows. The detection of photovoltaic power generation facilities using unmanned aerial vehicles was effective in analyzing the location and area of photovoltaic panels located on the roofs of buildings, and it was possible to calculate the expected power generation by region through the area calculation of photovoltaic panels. The vacant house detection can be used to select an investigation target for an vacant house condition survey as it can identify damage to buildings that are expected to be empty houses, management status, and electricity supply facilities through aerial photos. It is judged that the unmanned aerial vehicle detection capability can be utilized as a method to improve the efficiency of investigation and supplement the data related to solar power generation facilities and vacant houses provided by public institutions. Although this study detected the status of solar power generation facilities and vacant houses through high-resolution aerial image analysis, as a follow-up study, automatic measurement methods using the temperature difference of solar power generation facilities and general characteristics of vacant houses that can be read from the air were investigated. If the deriving research is carried out, it is judged that it will be possible to contribute to the improvement of the accuracy of the detection result using the unmanned aerial vehicle and the expansion of the application range.
