Recently, rainwater harvesting facilities have increasingly constructed mainly in elementary schools and government buildings. Nevertheless, few methods are available for efficient planning and design of rainwater harvesting facilities by considering the weather conditions and purpose of rainwater management in each site, which may lead to a construction of uneconomic facilities. The current method estimates the size of rainwater storage tank by multiplying the size of building or plottage with a certain ratio and has many limitations. In this study, we first developed a method for planning and design of rainwater storage facilities using $Rainstock^{TM}$ model, which is based on mass balance, and economic analysis. Then, the model was applied for the design of a rainwater harvesting facility in a building with the catchment area of $1,000m^2$. The model calculation indicated that the economic feasibility of rainwater harvesting depends on not only the size of storage tank but also the water usage rate. When the water usage rate is $1m^3/day$, the rainwater harvesting facility is not cost-effective regardless of the size of the storage tank. With increasing the water usage rate, the economical efficiency of the facility was improved for a specific size of the storage tank. Based on the model calculation, the optimum tank sizes for $5m^3/day$ and $10m^3/day$ of water usage rates were $24m^3$ and $57m^3$, respectively. It is expected that the model is useful for optimization of rainwater storage facilities in planning and designing steps.
Korean cities need sustainable urban regeneration based on the effective application of space and resource. Especially a sustainable urban regeneration needs the activation of community in the urban underground space as urban development center. The purpose of this study is to propose elements and factors of spatial planning of community in urban underground space for sustainable urban regeneration and to propose the characteristics of spatial planning of community in urban underground space according to strategies of sustainable urban regeneration. The research methods of this study used to conduct research include precedent study reviews and survey. The conclusions of this study are as following; The application of various factors related to spatial planning aspect of communication, supportive cultural facilities, accessibility and nature is needed for creating a sustainable urban regeneration. Especially, in urban underground space, the application of spatial planning for community activation considered strategies of sustainable urban regeneration should be necessary.

This study aims at revealing important utilization planning by surveying and analyzing unused classrooms in primary school's facilities. That is various and positive utilization planning of unused classrooms in order to cope with the changes of educational environment focused on high and multi-functionization, rather qualitative aspect than quantitative. By field-survey and interview, physical and environmental factors such as, the change procedure of students, unused facilities in schools and improvement affairs and purpose stressed by schools were surveyed. Additionally, the way of educational facilities to future society linked with residents was examined by surveying about the relationship between educational facilities and regional communities. The curriculums and "School facilities standard ordinance" have been revised in part by several times individually and couldn't meet with educational facilities, educational and social change positively. In rural area, to apply the standard of the capacity by a class with 40 students like city is not desirable. To make educational environment better qualitatively, the capacity should be reduced by 30 students and the unit square per a student enlarged by $2.4m^2$. By room unit module "school institution and managerial regulations under high school" should be applied distinctively to break down like 6, 7~12, 13~24 and over 25 classes. So re-institution of the capacity by a class and the standard unit of the number of class by scale is needed.

In the 21st century numerous universities continue to have an interest in building a more sustainable campus. The concept related to sustainable development and sustainability is applied to new master plan of university or university building planning. The field of sustainable development can be conceptually broken into three constituent parts: environmental sustainability, economic sustainability and social sustainability. The realization of sustainable development will become when considered eco-friendly life of users, not only environmentally friendly technologies. This study aims to research the method of sustainable access to university building planning in Europe and Canada. First, certification and standards will focused on acquisition Green Building Certification. Then we look at trends of sustainability based on users and community through the system of prior consultation between university and users. For the desirable development of the sustainable campus, the sustainable planning of campus should be investigated with campus community, members and local residents considering the generation, the preservation, the maintenance of existing building.
Elderly welfare housing refers to a residential facility with diverse medical and welfare services for cohabitation of elderly. Especially, community shared spaces in the elderly welfare housing plays an important role as a place for community and leisure activities that enhance vitality of elderly life. The purpose of this study was to investigate types, planning characteristics and actual utilization of community shared spaces in for-profit elderly welfare housing. Eight for-profit elderly welfare housing facilities in Seoul and Gyeonggi province were selected for this study and categorized into small-, medium- and large-scale facilities based on the number of housing units. Community shared spaces in the elderly welfare housing were classified into six space types: social space, education space, exercise space, medical space, convenience space and leisure space. Findings are as follows. Small-scale elderly welfare housing facilities with less than 100 housing units had fitness centers, clinics, restaurants, convenience stores and hobby rooms which were required by law. All community shared spaces were planned on a single level. Fitness centers was found the most frequently used while the other spaces were not used very frequently. Medium-scale facilities with 100 to 299 housing units had multi-purpose halls, libraries, swimming pools, indoor and/or outdoor driving ranges, physical therapy centers, saunas, karaokes and so on. Most community shared spaces were found frequently used. Large-scale facilities with 300 or more housing units had religion rooms, community halls, hair salons, pharmacies, etc. In most facilities, community shared spaces were planned in distributed locations.

This study analyzes the multiple effects of the following three aspects of waterscape facilities within apartment complexes: planning/designing, maintenance/management, and use of the facilities and suggests primary documents that will be fundamental for the methods to accelerate the implementation of waterscape facilities. A survey and analysis was conducted among a few of the most representative private apartment complexes in Seoul in accordance with the management and operation of waterscape facilities. The analysis used frequency analysis, descriptive statistics, reliability test, t-test, and PLS regression analysis. The research findings are as follows: first, the degree of use of waterscape facilities was found to be low regardless of the levels of operation, but residents' preference for the facilities was shown to be high, thus indicating there are still high expectations on the part of residents. Second, regardless of whether the facilities are being operated efficiently, the two items of location and display method under the section of planning and designing and the two items of aptitude and convenience under the section of use were found to positively affect the operation and use of waterscape facilities. Particularly, the item of freshness, cleanliness was shown to be directly and indirectly correlated with obsolescence, administration costs, and noise, which negatively affect the operation. Third, it was found that the administration costs itself that had been shown as the most negative factor of operating landscaping facilities in previous research did not cause problems in the residential area where the facilities are not operated efficiently. The finding suggests that the administration costs do not matter but that in the case of experience- and entertainment-typed facilities that residents want, they are linked to problems that do not introduce the desired facilities. Fourth, it was found that various aspects of planning, designing, maintaining, and using facilities interconnect and affect one another in the process of operating and using waterscape facilities resulting in the need to have a comprehensive approach to these three factors of planning, design, maintenance, management, and utilization. This study proposes that the needs and values of residents should be reflected to activate the introduction of landscaping facilities in the apartment complexes.
One of the most challenging safety precautions for workers in dynamic, radioactive environments is avoiding radiation sources and sustaining low exposure. This paper presents a sampling-based algorithm, DL-RRT*, for minimum dose walk-path re-planning in radioactive environments, expedient for occupational workers in nuclear facilities to avoid unnecessary radiation exposure. The method combines the principle of random tree star ($RRT^*$) and $D^*$ Lite, and uses the expansion strength of grid search strategy from $D^*$ Lite to quickly find a high-quality initial path to accelerate convergence rate in $RRT^*$. The algorithm inherits probabilistic completeness and asymptotic optimality from $RRT^*$ to refine the existing paths continually by sampling the search-graph obtained from the grid search process. It can not only be applied to continuous cost spaces, but also make full use of the last planning information to avoid global re-planning, so as to improve the efficiency of path planning in frequently changing environments. The effectiveness and superiority of the proposed method was verified by simulating radiation field under varying obstacles and radioactive environments, and the results were compared with $RRT^*$ algorithm output.
Long distance trail or trail system planning is the first important step in transforming your vision into reality. Planning presents a vision for a trail or trail system and brings a comprehensive, long-range perspective. The master plan provides solid, credible recommendations for developing a trail or trail system that is safe, convenient, well used, supported by local residents, practicality to implement, and customized to meet the needs of the community, you will need to follow a logical planning. The key elements of master planning includes site assessment, vision, goals and objectives, routing and design, implementation strategies. Trails or trail systems should provide linkages to popular destinations, safely accommodate a variety of users, and be sensitive to any negative impacts on the natural environment and wildlife. Trails planners also need to think about how the trail, or trail system will function in the future as areas are developed or trail population increases. All of these factors during the planning process will ensure the existence of high-quality facilities for years to come. Project for Nakdong-jungmaek trail planning combine long distance trail with circuit way. That project is a planning brought out the best in each of Tokai natural way and Cotswold way. That is planning which is combined a wooded trail in Tokai natural way with access and facilities improving economy in Cotswold way. Also That planning embraces a core cultural center which is concerned forest or wood to come more people.

According to the Ministry of Land, Infrastructure, and Transport, the total area of unexecuted urban planning facilities in Korea is about $1,257km^2$, of which 47% is the unexecuted urban green space and forests. In the case of Seoul, the total area of unexecuted urban planning facilities is about $66km^2$, which is 5.24% of the total unexecuted area in the entire country. In Seoul, approximately 88% of the total unexecuted area is urban green space and forests, which is higher than the national rate. About 92% of the unexecuted urban planning facilities are long-term unexecuted urban planning facilities that are more than 10 years old. This study assessed the economic value of potential ecosystem services, focusing on the regulation service, supporting service, and cultural service, for urban green space and forests of unexecuted urban planning facilities in Seoul by using meta-regression analysis. As a result, the value of the regulation service provided by the urban green space and forests in Seoul was about 16.39 billion KRW, the value of the supporting service was about 5.8 billion KRW, and the cultural service value was about 7.78 billion KRW. The total value of ecosystem services is about 33.93 billion KRW. The values of regulation service and cultural service were the highest, and that was attributed to the characteristics of the downtown area. The significance of this study is to evaluate the value of ecosystem services for unexecuted urban planning facilities in Seoul. The results of this study can be used not only in the process of urban planning or policymaking but also land compensation methods applying the concept of an ecosystem service payment system.
Based on an analysis of the characteristics of "Ecute" of the East Japan Railway Company (JR East) that planned the world's first large scale commercial facilities inside a ticket gate (paid-area including waiting room and platforms), the present study proposes a brand development of commercial facilities inside aged railway stations, where only basic railway business have been provided focusing on passenger transportation, by renewing the definition of railway commercial facilities and presenting a detailed planning and the direction of the operation system. A list of practical tasks that can be carried out in academia, planning and operation / management to facilitate the revitalization of the use of commercial facilities inside railway stations are as follows: 1) the setting of a wide scope for the revitalization of railway commercial facilities around the railway station focusing on private-funded stations in addition to existing stations; a setup of the direct scope of commercial development in the practical railway operation for passengers and stations in terms of external research, and a corresponding shift in thinking in terms of internal research 2) development of under used spaces such as the transfer area (Gongdeok Seoul Wangsimri Station are first target stations where more than four subway lines intersect) 3) brand establishment through improvement strategies for image and symbolism specialized for railway stations 4) rent of suitable business stores and layout of commercial facilities by analysis of passenger move pattern 5) development of commercial facilities which can attract customers by displaying various products, as well as finding a way to develop them in to a base facility that connects to local infrastructures 6) providing advertisement and management system for continual maintenance, and 7) brand specialization through unique storytelling and design plan that stimulates sensibility. The above study results can be utilized as a starting point for design brand awareness about commercial facilities in railway stations in Korea, which can be developed further to improve station image and passenger convenience, as well as to increase the revenue of railway businesses.
