Establishments of wholesale of recycling materials are located in the region where an amount of recyclable wastes generated as artery industry developed and the region of rather many population. And they are located not in underpopulated area as noxious facilities, but located in the non-residential area of many population regions in the whole country. Also, establishments of recycling of metal wastes and scrap, and non-metal wastes and scrap are mainly located in the peripheral region of metropolitan cities, regional centered cities, and adjacent regions of industrial area, because of high coefficient of localization, and agglomerated effects of production. The factor influencing the location of recycling industries is deeply connected with the location of wholesale of recycling materials, and thus, the transportation costs to carry recycling materials from supplied regions to plants are important but population is not so important.

The purpose of this study is to identify factors influencing suicidal ideation for the elderly living alone. Utilizing the identified factors as the base data, the study aims to develop community programs for suicide prevention. This research is a secondary analysis of the 2017 national survey, 'Survey on the Elderly,' conducting logistics regression analysis on the data collected on 10,299 elderly aged 65 or older living in 17 general residential facilities as of 2017. The analysis reveals that 10.5% of the elderly living alone have contemplated suicide. The frequency of suicidal ideation was attributed to such factors as gender, age, chronic disease, depression and experiences of abuse and discrimination. To prevent suicide among the elderly, therefore, active management from both public and private sectors are needed for early detection of chronic diseases and depression.

The purpose of this research is to determine the deterioration characteristics of high-rise and high-density apartment complexes in 1st period new towns in order to regenerate apartments as sustainable residential environments in Korea. For this purpose, the level of deterioration was evaluated by using 'evaluating indicators of the level of deterioration of high-rise and high-density apartments'. The deterioration characteristics were determined inclusively and concretely based on evaluation results. In addition, the deterioration level according to residents' awareness of the deterioration of their apartment was evaluated. This study was conducted by methods of field data collection, staff interview, field measurement, and resident survey according to the measurement of the evaluating indicators. And the re-organized questionnaire based on the evaluating indicators was utilized for a survey of resident's awareness. The results are as follows: In the physical dimensions of apartments, the deterioration characteristics included deteriorated equipment and a decline in structural performance due to the aging of the apartment, a shortage of parking spaces, and the low flexibility of the bearing wall structure, etc. In terms of the social dimensions, the apartments showed an increase in the number of elderly households, a shortage of community facilities, and a lack of the opportunity for community participation etc. In terms of the economic dimensions, the apartments showed limitations in maintenance & repair and a lack of environmentally friendly features.

The street system in multi-family housing is an important design element to control the circulation of vehicles and pedestrians, and to form the spatial organization of the projects. In particular, in the case of high-rise apartments, the street patterns have an influence on the safety, amenity, and convenience of facilities. Until now, however, the design of street patterns in most high-rise multi-family housing projects has diminished the quality of residential environments because priority of design consideration has primarily been given to planning road ways and parking areas. Nevertheless, the design competitions introduced for the first time in the 1980s have played a significant role in developing fresh ideas and concepts in housing design. Because street patterns have been respectably modified as a result of the generalizing of design competitions, it is important to review the ideas that have been proposed in competitions over the recent past. In this context, this study classified the types of street patterns and analyzed their design characteristics for the proposals of housing design competitions since the 1990s. As a result of this analysis, the road patterns are classified into 4 types: 1) serial type, 2) isolated type, 3) mixed type, and 4) not a road pattern due to the system of connection. In addition, these were further divided into 8 types: 1) loop, 2) ring, 3) penetration, 4) tree, 5) direct entry, 6) ring and penetration, 7) loop and penetration, 8) not a road pattern due to appearance and the collector.

Canada is a democratic country, yet it keeps a social democratic system in which the government is in charge of welfare of its people. And this is one of the most significant features about the country. Her public and private pension system has been effective since the 1920s, securing its people's fundamental income. In particular, the public medical system applies to its every citizen and performs its role. This system is called the National Medical System as well as "MEDICARE" named after its related law. However, there has been a significant change in the national medical and welfare policy due to the budget deficit. In other words, the policy was mainly implemented to welfare facilities in the past, but the policy changed to a welfare policy for the elderly with a concentration on the support for self-reliance of senior citizens since the reform. The purpose of this study is to provide data and implications for Korea through the analysis of the current situation and distinct features of the housing welfare system in Canada. This study has researched the literature on the subject with an analytic focus on three aspects that are the fundamental frame of the system, essential content (support for self-reliance and facility composition), and distinct features of the housing for the elderly. In other words, they are, first, how the fundamental frame of the housing welfare system for the elderly is composed; second, how the service for self-reliance welfare and facility service are composed; and third, what their scale and distinct spatial features of general houses for the elderly with self-reliance are. A comparative study was conducted in detail on courses and characteristics of the housing welfare system for senior citizens in Canada and the USA of North America. In particular, it reveals the scale and distinct spatial features of public houses for the elderly with self-reliance in British Columbia (BC) which is one of the main provinces of Canada.

The high intrinsic water content and salinity of food waste prevent a smooth composting process and consequently cause social, economic and environmental problems. In this study, we investigated the distribution of the water content and salinity in food wastes to obtain useful primary data to ensure adequate and quality recycling. A total of 300 food waste (FW) samples were collected from residential apartments (home generated FW), a wide range of restaurants, i.e., restaurant generated FW that included Korean, Chinese, Japanese and western FWs, and several places that included food waste processing facilities (dehydrated FW cakes). The collected food wastes were oven dried for 48 hours at 80℃ after which the water and salinity contents were analyzed. The results show that the average water content of the FWs was 72.45 ± 10.51%, and the average salinity content was 2.03 ± 0.57%. Furthermore, the salinity of the collected FWs was characterized by where the FW was generated. By location, the salinity concentration of home generated FW was 2.30% while western food had the lowest salinity concentration of 1.18%. However, dehydrated cakes had the highest salinity concentration of 2.84%. Especially, the distribution of the salinity content in food wastes can form the basis for improving the compost quality in food waste recycling.

Objective: Emissions of volatile organic compounds (VOCs) from municipal wastewater treatment plants and industrial wastewater are often overlooked as sources of exposure to toxic chemicals. VOCs from such sources evaporate readily into the air and may have significantly adverse impacts on public health. The present study aimed to establish the concentration of VOCs released from Jangrim-sinpyoeng Municipal and Industrial Wastewater Treatment plant (JWTP) in Busan, South Korea and assess the causes of the odor/stench in the surrounding residential facilities. Stench intensity, frequency and release time, and wind direction were also monitored. Methods: Onsite data were collected on a daily basis from a laboratory located on the JWTP premises through a period spanning 2006 to 2010. A second set of data was obtained in 2006 by conducting a questionnaire survey with 210 respondents living near JWTP. The experimental and survey data were analysed statistically using the SPSS package. Results: The survey results showed that people residing around JWTP strongly perceive a stench from the plant. The intensity of the stench was influenced significantly by wind direction and the location of the apartments facing the JWTP. Public participation formed a significant step in determining the quality of the study environment. Conclusion: Onsite data and survey data obtained in 2006 indicate that the nature of the odor experienced by residents is due to the intensity of total VOCs released by JWTP. However, additional research is needed to determine the effects of the VOC pollution on public health and quality of life.

Recently, park usage for environmental education has gained popularity in Seoul. Therefore this study was performed by analyzing the status and problems of nature classrooms in neighborhood parks and citizen's parks that are located in residential areas in Seoul, and then by suggesting improved methods and user programs. The results of this study are summarized as follows. 1) 18 out of 281 neighborhood parks and citizen's parks have nature classrooms in Seoul. Facilities of nature classroom are comprised of direction signs, plant name card, pond, pavilion, pergola, bench, green house, waste baskets, lighting, drinking fountain and others. However, they have many problems in terms of quality. Nature classrooms were classified into three types according to their location in each park. Among the three types, the most popular type was the one that is a part of a park A Total of 479 species of plant (155 species in tree, 324 species in herb) were planted in nature classrooms. There are many kinds of environmental education user programs, but these are not connected with the nature classrooms. Most nature education programs in nature classrooms were self-guided. 2) The Problems that appeared were the featureless place composition, a lack of programs related to nature classrooms, access restriction to certain natured areas, and so on. 3) Finally, this study suggests some solutions to the problems of nature classrooms in urban parks. The solutions include full access to the parks, the creation of diverse theme, and setting up interesting panel and leaflets in order to encourage more active self-guided education.

The purpose of this study is to propose a power demand volatility evaluation system based on LSTM and not to verify the accuracy of the demand module which is a core module, but to recognize the sudden change of power pattern by using deeplearning in the actual power demand monitoring system. Then we confirm the availability of the module. Also, we tried to provide a visualized report so that the manager can determine the fluctuation of the power usage patten by applying it as a module to the web based system. It is confirmed that the power consumption data shows a certain pattern in the case of government offices and hospitals as a result of implementation of the volatility evaluation system. On the other hand, in areas with relatively low power consumption, such as residential facilities, it was not appropriate to evaluate the volatility.
