After increasing to 84 trillion yen in FY1992 following the burst of Japan's economic bubble, construction investment in Japan fell to 42 trillion yen in FY2010 in the wake of the global financial crisis. It subsequently recovered to 67 trillion yen in FY2022, driven largely by demand for reconstruction after the Great East Japan Earthquake and Abenomics. On the other hand, the sustainability of Japanese construction is under threat due to a declining population and a decrease in the number of construction workers. A breakdown in sustainability is not only detrimental to the population, but also leads to delays in disaster recovery for Japan, which is a disaster-prone country. It is therefore necessary to analyze the status and trends in building construction in recent years to clarify the future sustainability of building construction in Japan. This study reviews basic information on buildings constructed in recent decades using raw data from the Statistical Survey of Building Starts, a statistical survey undertaken by the Japanese government, and analyzes statistical data such as number of buildings, location, building type, total floor area, construction cost, and construction duration. Finally, the sustainability of building construction in Japan is discussed.

This study emphasized the soil of environmental impact assessment to devise measures to minimize the negative impact of project implementation on the environment. As a series of efforts for impact assessment procedures, a national inventory-based database was established for urban development projects, and three machine learning model performance evaluation as well as soil pollutant concentration distribution mapping were conducted. Here, nine soil pollutants were mapped to the metropolitan area of South Korea using the Random Forest model, which showed the best performance. The results of this study found that concentrations of Zn, F, and Cd were relatively concerned in Seoul, where urbanization is the most active. In addition, in the case of Hg and Cr6+, concentrations were detected below the standard, which was derived from a lack of pollutants such as industrial and industrial complexes that affect contents of heavy metals. A significant correlation between land cover and pollutants was inferred through the spatial distribution mapping of soil pollutants. Through this, it is expected that efficient soil management measures for minimizing soil pollution and planning decisions regarding the location of the project site can be established.

The environmental impact assessment have been played important role for sustainable development of the country. Meantime, various studies have been conducted for scientific and effective environmental impact assessment. Howeverthe quantitative data such as regional distribution status and development characteristics according to the type of development project, environmental changes due to development projects, and spatial-temporal changes are insufficient, currently. In this study, we investigated the eco-friendliness of major development projects (industrial complex, urban development, tourist complexes, and waste disposal equipments) by integrating the EA-INDEX of each development projects which were reported by prior researches. As a result, we found that the eco-friendliness of development projects tended to gradually increase overtime due to the increase in eco-friendliness in the protection of living environment sector. The protection of living environment sector was a major factor in the the eco-friendliness of industrial complexes and urban development projects. In the case ofroad construction, landfill and tourist complex development projects, the natural environment conservation sector was a major factor in the eco-friendliness of the project. As a result of analyzing the eco-friendliness of development projects by local government, the eco-friendliness of development projects promoted and implemented in Ulsan, Jeonnam, and Gwangju was higher compared to other regions, and it was relatively low in Daejeon, Gyeongnam, and Daegu. This study is considered to be significant in that it conducted a quantitative analysis of the eco-friendliness of development projects carried out over a relatively long period of time throughout South Korea by dividing them by year and local government.

The purpose of this paper is to suggest the improvement method to achieve the interactive development effect between high-tech industrial complex and its surrounding areas. For this reason, this paper has conducted an empirical analysis to find out relevant comprehensive factors, affecting nearby housing prices from such plans, especially by reviewing 'Seoul Digital Industrial Complex.' This paper is truly differentiated from previous research by adding a new perspective 'diverse location characteristics', as it focuses not only on 'high-tech facility' characteristics, but also on 'urban function facilities', including 'transportation facilities', 'amenity facilities', 'security facilities', etc. Then, SPSS Version 18.0 was utilized to conduct the multiple regression analysis with the accumulated relevant data and several results were drawn out as following: Firstly, 'deterioration level', 'brand of apartment', etc. are found to be major influencing factors. Secondly, 'educational facilities', 'transportation facilities', 'Cultural & Sports facilities', 'Amenity facilities', etc. are found in the sector of 'location characteristic'. Lastly, 'leading companies within the industrial complex', were also found, affecting nearby housing prices. Therefore, when a housing development project is planned to grant the interactive development effect to high-tech industrial complex and its surrounding housing areas, it is necessary to consider variety factors, such as comprehensive location characteristics and housing complex characteristics, and also proper housing policy measures should be devised in accordance with the actual demand of employees and their dependant family members.

The trends of Green growth and environmentally-friendliness came to be the key development indicator for sustaining global environment for the future. Korean government reflected these trends in the main flows of the national development index. Korean construction industry is concentrating investment on fields related to these trends such as technologies for carbon dioxide deduction, materials or products for environmentally-friendly building and alternative energy development, as well. However, efforts to follow these trends during the construction process as a step for production phrase are not being considered enough. In this study, we analysed current status and points to be improved of on-site environment management by surveying major project owners and representatives of the environmental affairs in the leading companies of those fields. Also, we suggested organizational structure and operation model as a solution for enhancing environmentally-friendliness for systematic approach to manage on-site environment in public construction sites. In addition to these solutions, further approaches such as shifting paradigm of project owners and contractors, securing workforce and practical budget for efficient management activities, developing environmental management manuals, setting standards for evaluation of activities are needed for the stable settlement of on-site environmental management.

Rural tourism has been identified as providing opportunities to revitalize the rural economies since early 2000s. During last decade in South Korea, government has enacted many policies aiming to establish tourism support programs as well as instigating activities between rural and nearby urban districts. In particular, the promotion of the rural tourism has been actively sought in various forms of products and services, such as green tourism village, village festival, one-company one-village campaign and etc. However, in order to prepare effective policies, it is very crucial to identify measureable evaluation criteria that can be used to assess socio-economic situations of the rural districts. Such criteria should be objective, timely and provide insights about living conditions of local residents and relevant properties. They can also be used to evaluate if progress is being made after the policies are implemented. While considerable efforts and resources have been invested to aid the tourism programs in South Korea, we still lack such systematic means to quantify and evaluate its impact on rural districts. In this work, we have applied regional deprivation analysis on well-established community experiential and recreational business in rural villages throughout the country based on three criteria (i.e., population, local commerce, and buildings). Surprisingly, the result shows that the implementation of the community experiential and recreational businesses did not bring any noticeable changes to at least one of the evaluation criteria. We concluded that the current government policies on revitalization of rural tourism at the village scale is insufficient for bringing meaningful socio-economic impacts to rural districts, with rare exceptions.

Despite the intensive family Planning program of the government, which has reduced the :average population growth to 2.0 percent in 1970, the continuing high fertility rates and poor family planning services in urban slum areas has been continually pointed out by various evaluation seminars. Thus, it was felt that a study of the current status of family planning in an urban slum population was needed. The aims of the study were to: (1) delineate the general characteristics of the urban slum population (2) discover the knowledge, attitudes, and practice of family planing. (3) determine what was felt to be the ideal number of children. (4) determine the status of induced abortion. A random stratified sample of 200 women was selected from a population of 3, 118 married women, 20-49 years of age, living in the Yonsei Community Health Project area and registered at the Yonhee Community Health Service Institute. The respondents were interviewed by the investigates, using a pretested questionary, from the period of October 1 to October 30, 1972. The findings of the Study were as follows: 1. Afore than half of the respondents were in the high fertility age group (25-34): of lower educational level (under primary School) : from rural areas: and with unstable sources of income. 2. The average respondent had 3.6 living children. 3. Most of the respondents had knowledge of contraceptive methods such as the Loop(78, 5%) and Oral pill (87.0%). 4. Seventy seven percent of the respondents recognized the Health Center as an available source for family planning. 5. About seventy percent of the respondents approved of family planning. 6. Eighty four point five percent of all the respondents answered that using contraceptives is harmful to maternal health. 7. Currently, 21.0 percent of the respondents were using contraceptives, while 40.0 percent of the respondents were current users or had used contraceptives. 5. Of the respondents who had ever stopped using contraceptives, 78.0 percent gave side effects as the reason they discontinued the method. 9. The average number of ideal children reported by the respondents was 3.5. 10. If they had only 2 daughters, 85.5 Percent of the respondents thought they must have more children. 11. Sixty nine point five percent of the respondents approved of induced abortion for unwanted pregnancies, while 34.5 percent of the respondents had experienced induced abortion for unwanted pregnancies. The mean number of induced abortion for unwanted pregnancies was 0.7. 12. The result of this study showed that such urban slum population would be one of the most important target of the family planning services, therefore further social-psychological researches with technical development on this area are recommended.

The study area,Cheonan Stream, is an urban river that flows through urban areas in close proximity to densely populated areas and multi-use facilities. The natural river improvement project from 2006 to 2015 improved the quality of life of local residents with the improvement of river function, the restoration of the natural ecosystem and the securement of hydrophilic space. A bike way in the constructed waterside space was built focusing on trails. This study suggests improvements appropriate for insufficient bike way function-related regulations. The problems of ramps, river crossing facilities, stairway facilities, safety facilities, signs, road markings, and parking facilities, etc.have arisen in the utilization situation and citizen consciousness survey. As an improvement, it was suggested that 12% or fewer ramps should be improved, a submerged bridge should be installed at 7 places separated by stepping bridges, and signs and road markings according to bike way-related regulations should be installed and bike parking facilities at Cheonan station and Cheonan bus terminal should be expanded. The bike way in the waterfront of ChoenanCheon(river) will increase the accessibility and utilization rate of short-distance transportation with the institutional expansion of bike use facilities and work organizations and the improvement of facilities in accordance with urban rivers and bike-related regulations. Therefore, it is expected that the development of the living space will be beneficial for the citizens due to the elimination of traffic in the city and the activation of bike traffic.

The information generated from large and complex construction projects transfer and evolve in long-term business cycle. Therefore, while there is any problem, such as delay, the cause of the problem might relate to the previous business process rather than where it arises. However, for complex project players and business relationships, it is unsuitable to search an information flow using traditional retrieval methods. This research addresses a relationship-based information search system to analyze the information flow in large-scale and complex construction projects. First, we identified the components of the information retrieval system customizing for a large-scale complex construction projects, and then developed the inference algorithm which define the relationship between business processes. For the validation, we applied the system on a business information system of urban regeneration projects and suggested some application using information flow retrieval system for project players and project managers. Using the system, players are easy to prepare for their work process and managers can define the causal flow of the problem.
