The case for study in this paper is the Main Plan and Management for the Fukutoshin; the restructure of Nishi Shinjuku, This plan was first outlines in 1960, and includes a vast area of 96 ha for redevelopment. It aims to create a totally new center in the city. This was the first case in Japan, and in the world of a plan of these magnitudes. involving urban landscape restructuring from three points: Landscape (open spaces for public use: the Shinjuku Central Park and the surrounding area of the buildings), transport and commercial building developments. The Landscape plan for the green areas was decided in a way to compensate the population of the area and the visitors. As a rule, high-rise building constructions are placed each one in single lots and are surrounded by open spaces and greenery. Pedestrain areas are widened and also connected by bridges in a way to allow free circulation, and interconnection between the constructions and the green areas. Another important factor is the role that Private Corporation, and public interest plays. Joining these two forces has allowed the concretization of this project. This interpolation between public and private roles was an innovation in Japan, and it also the key for the concretion of the project. The historical review of the process and management of this project help us to put into perspective the introduction of new concepts and ideas, which were not related at that time to traditional Japanese Landscaping. Furthermore we are better able to understand the substantial increase in the percentage of land dedicated to green areas in contrast to the typical standards of Japanese cities.

본 연구에서는 해외 산업단지 건설의 국내경제 파급효과를 극대화하기 위한 방안을 도출하는데 목적이 있다. 이를 위해 해외 건설협회의 준공실적 원시자료와 산업연관모형을 응용하여 산업단지 개발단계별(조사설계, 단지조성, 공장건축) 유발계수를 도출하였다. 분석결과, 도시용역은 인건비 비중이 높게 나타나고 있으며, 단지토목은 손익액 비중이 높게 나타났다. 이에 비해 공장건축은 중간투입비중과 손익비중이 높게 나타났다. 결국 동일한 공종과 비교할 때 산업단지의 해외개발은 고용측면에서는 용역이, 기업의 영업잉여 측면에서는 토목과 건축이, 국가경제 측면에서는 건축의 효과가 크게 나타난다. 따라서 우리나라 국내경제 파급 효과를 극대화하기 위해서는 단순히 해외 산업단지 개발을 통해 부지를 분양하는 사업구조보다는 산업단지 내 공장 건축까지 사업에 포함할 수 있는 수주전략을 도모할 필요가 있음을 시사한다.

이 연구에서는 미분양 아파트 단지의 세대별 계약 자료에 데이터 마이닝 기법인 의사결정나무, 신경망, 로지스틱 모형을 적용하여 세대별 초기계약을 예측하는 모형을 개발한다. 모형 개발에는 위례신도시 미분양 아파트 단지의 계약 자료가 이용되며, 이 자료는 훈련용 자료와 검정용 자료로 분할되어 분석에 투입된다. 훈련용 자료에서는 신경망, 의사결정나무, 로지스틱 모형 순으로 예측력이 뛰어났지만 검정용 자료에서는 로지스틱 모형이 가장 우수하게 나타났다. 이 같은 결과는 신경망이 훈련용 자료에 최적화된 모형으로 구축되면서 검정용 자료에 대한 적응성이 떨어져 나타난 결과로 판단된다. 의사결정나무와 로지스틱 모형을 병행 적용한 결과, 층수, 향, 세대 위치, 전기 및 발전기실의 소음, 청약자 거주지, 청약 종류가 초기계약에 영향을 주는 것으로 나타났다. 이는 두 가지 모형을 같이 사용하는 것이 초기계약 결정요인 발굴에 더 효과적이라는 것을 의미한다. 이 연구는 데이터 마이닝의 적용 범위를 주택 분양 예측까지 확장함으로써 융복합 분야 발전에 기여하고 있다.

This study suggested the necessity of introducing the future-oriented new industrial complex as a way to enhance the competitiveness of the industrial complex in response to the industrial ecosystem change caused by the 4th industrial revolution. To evaluate the location suitability for the new industrial complex, location indices were developed in this study. The flexibility of location and connectivity to neighboring areas of the future-oriented new industrial complexes were the focused subjects of this study. In-depth expert consultation and Delphi survey were conducted to construct an index system and to measure the indices. Afterwards, the AHP analysis was conducted to elucidate the weighting by indicators. As a result, the indicators of industrial innovation environment were the most important in the major category. In addition, the convenience of workers, especially urban environment, was analyzed as an important factor for success of the future-oriented new industrial complex. The indicators which are closely related to the concept and purpose of the future-oriented new industrial complex turned out to have the higher weight compared to other indicators. From the point of view of the developers of the industrial complexes or tenant companies, the implications for deriving suitable locations for development of industrial complexes among urban under-utilized sites are suggested. Furthermore, It is expected that the government will be able to apply the development system to stimulate the development of these new industrial complexes and to prepare guidelines for selecting locations.

Continuous global warming is causing ecosystem destruction and direct damage to human life. The main cause of global warming is greenhouse gases, which account for more than 90 % of carbon dioxide. The leaders of each country signed the Paris Agreement at the United Nations Convention on Climate Change (UNFCCC) to reduce greenhouse gas emissions. Currently, the total amount of CO₂ emitted from South Korea is 664.7 million tons as of 2018, ranking eighth in the world. 37 % of South Korea's total CO₂ emissions come from the construction & building field, especially the cement production, which is a construction material. Carbon reduction technologies can be largely divided into four types: carbon reduction (CC), carbon reduction and storage technology (CCS), carbon reduction and utilization technology (CCU), and carbon reduction, storage and utilization technology (CCUS). Overseas, CCUS technology is mainly applied to reduce and store CO₂ emitted from construction and construction field. A technology for permanently storing CO₂ through mineralization by capturing CO₂ and utilizing CO₂ into a cement production process was developed, and this technology is applied to the entire cement industry. However, the development of CCUS technology applicable to the cement industry is still insignificant in South Korea. In this study, carbon dioxide reduction technology and methods for reducing carbon dioxide emitted during the cement manufacturing process, which is the main component of concrete mainly used in civil engineering construction, were investigated. Overseas, it has reached the commercialization stage beyond the demonstration stage as a way to reduce carbon dioxide by vomiting carbonation reactions. Accordingly, if carbon dioxide reduction plan technology generated during cement manufacturing is developed based on domestic technology differentiated from foreign technology, it is expected to contribute one more step to the carbon neutrality policy.

Objectives: Fine particulate matter pollution has emerged as a significant life-threatening issue in Thailand. Recognizing the importance of environmental health literacy (EHL) in disease prevention is crucial for protecting public health. This study investigated EHL levels and aimed to identify associated factors among village health volunteers (VHVs) in the upper northern region of Thailand. Methods: A cross-sectional study was conducted to collect data from 710 VHVs using the EHL assessment tool developed by the Department of Health, Thailand. Results: The overall EHL score was moderate (mean, 3.28 out of a possible 5.0), with the highest and lowest domain-specific mean score for the ability to make decisions (3.52) and the ability to access (3.03). Multiple linear regression revealed that the factors associated with EHL score were area of residence (urban areas in Chiang Mai: B=0.254; urban areas in Lampang: B=0.274; and rural areas in Lampang: B=0.250 compared to rural areas in Chiang Mai), higher education levels (senior high school: B=0.212; diploma/high vocational certificate: B=0.350; bachelor's degree or above: B=0.528 compared to elementary school or lower), having annual health checkups compared to not having annual health check-ups (B=0.142), monthly family income (B=0.004), and individuals frequently facing air pollution issues around their residence (B=0.199) compared to those who reported no such issues. Conclusions: The VHVs exhibited moderate EHL associated with residence area, education, health check-ups, family income, and residential air pollution. Considering these factors is vital for enhancing VHVs' EHL through strategic interventions.

글로벌 스마트도시 추진 동향을 기반으로 2018년 '4차산업혁명위원회'는 국내 스마트도시 정책의 방향과 관련하여 '지속가능성'과 '사람중심'을 핵심 키워드로 선정하였다. 이에 따라 국내 스마트도시사업 추진단계별로 적극적인 시민중심의 혁신 방법론인 리빙랩 프로그램을 적용하고 있다. 스마트도시는 리빙랩을 통해 시민이 중심이 되어 지역문제를 발굴하고, 공공·전문가와 함께 시민의 니즈(Needs)를 반영한 해결방안 도출을 통해 지속가능한 도시문제 해결방안 및 지역발전 방안을 마련하고 있다. 그러나 상대적으로 오랜 시간 운영된 도시재생사업과 비교할 때 스마트도시사업의 시민참여는 그 수준이나 지속가능성에서 상당한 차이가 있는 것으로 나타났다. 이에 본 연구는 2018년부터 2019년까지 추진된 스마트도시사업에서 수행한 리빙랩 프로그램 사례를 대상으로 도시재생사업 단계별 시민참여 특성과의 비교 분석과 Arnstein의 '참여의 사다리' 모형을 기준으로 한 시민참여 활동 수준진단을 수행하였다. 진단결과, 스마트도시사업에서 수행된 리빙랩에 나타난 시민참여 활동은 스마트도시서비스의 선정이나 해결책 구성 등에 상대적으로 높은 수준의 권한을 기반으로 지역주민의 수요에 맞는 스마트도시서비스를 선택하고 지역에 맞는 서비스의 기술수준이 결정되는 데 큰 영향을 보이고 있었다. 그러나 스마트도시 구축사업만을 위한 단발성 성격의 시민참여단 모집으로 사업 종료 후 에는 대부분의 시민참여활동이 중단되고 있었다. 이에 반해 도시재생사업의 시민참여 활동은 지역공동체 중심으로 사업 계획 단계부터 사업 종료 후 운영단계까지 지속적인 운영·관리 방안이 도출되고 있었다. 본 연구는 이와 같은 도시재생사업과 스마트도시사업간의 시민참여의 특성 비교와 수준진단을 통해 보다 지속가능한 스마트도시 구현을 위한 시민참여활성화 방안을 제시하였다.

클러스터에 대한 기존 논의는 성숙산업지역과 첨단산업지역의 차이를 크게 부각시켰으며 성숙산업지역은 혁신과 기업가정신이 미약하고 경쟁력이 약하여 혁신지역으로 변모하기 어렵다는 평가를 한다. 하지만 지역의 사회적 자본, 국지적 네트워크형성, 신뢰의 형성 등의 클러스터형성의 주요 요소는 산업형성의 기간이 오래된 성숙지역에 풍부하다고 할 수 있다. 성숙산업지역인 부천의 조립금속산업과 전형적인 혁신지구인 대전의 생물벤처산업의 혁신여건과 혁신출동의 여건분석을 통해, 두 지역의 혁신환경을 비교하고 클러스터의 특성에 따라 차별적인 지역내, 지역간 연계방안, 기업지원체제에 대한 시사점을 도출하였다.

In ballasted railway tracks, ballast fouling due to finer material intrusion has been identified as a challenging issue in track maintenance works. In this research, deformation characteristics of crushed stone-sand mixtures, simulating fresh and fouled ballasts were studied from laboratory and a 3-D discrete element method (DEM) triaxial compression tests. The DEM simulation was performed using a recently developed DEM approach, named, Yet Another Dynamic Engine (YADE). First, void ratio characteristics of crushed stone-sand mixtures were studied. Then, triaxial compression tests were conducted on specimens with 80 and 50% of relative densities simulating dense and loose states respectively. Initial DEM simulations were conducted using sphere particles. As stress-strain behaviour of crushed stone-sand mixtures evaluated by sphere particles were different from laboratory specimens, in next DEM simulations, the particles were modeled by a clump particle. The clump shape was selected using shape indexes of the actual particles evaluated by an image analysis. It was observed that the packing behaviour of laboratory crushed stone-sand mixtures were matched well with the DEM simulation with clump particles. The results also showed that the strength properties of crushed stone deteriorate when they are mixed by 30% or more of sand, specially under dense state. The results also showed that clump particles give closer stress-strain behaviour to laboratory specimens than sphere particles.
