  • The study aims to assess factors affecting intention to purchase green products in Vietnam. The study employs samples from customers who have actually experienced green consumption in Vietnam. The samples were collected by convenient sampling methods. The survey obtained 206 responses with full information. The survey was conducted from October 2019 to January 2020. The measurement scale was a 5-point scale with 1- completely disagree and 5- strongly agree. This study employs factor analysis and structural equation modelling analysis. The results showed that the social and environment sustainability awareness have positive effects on altruism of customers who are interested in green consumption. Altruism also has the same direction on green purchase intention. Besides, the attitude toward buying green and health consciousness affects green purchase intention. At the same time, the altruism and attitude towards buying green products also influence positively on green purchase intention. Besides, the health consciousness positively affects attitude towards buying green products. The results show that the health consciousness has a negative impact on intention to purchase green products. The findings suggest that it is necessary to raise customers' health consciousness, customers' altruism from disseminating knowledge about environmental protection as well as society to enhance the green consumption in Vietnam.

  • 이 논문은 한국에서 지방 도시들이 왜 제3세대 공공자전거시스템을 도입하는지 그리고 그 정책을 어떻게 유지하고 있는지를 분석하는 것을 목적으로 한다. 이를 위해 한국에서 가장 먼저 시도되었고 가장 성공적으로 정착되었다고 평가받는 창원시의 누비자를 사례로 선택하였다. 누비자의 성공적 도입에 중요한 역할을 한 요인은 다음과 같다. 첫째, 누비자는 창원시가 중화학공업도시로서의 이미지를 탈피하여 미래형 녹색 도시로의 변화를 추구하기 위해 환경수도를 선언하였을 때 그 구체적인 실행 전략의 일환으로 기획되었다. 둘째, 시장은 선진국 친환경도시의 환경정책 및 생태교통정책을 학습하고 이를 적극적으로 도입하였고 여기에 한국의 발달된 IT기술이 접목되어 성공적인 공공자전거시스템을 구축할 수 있었다. 셋째, 하향식 정치과정으로 인해 시정부가 시민사회나 의회의 참여 없이 독자적으로 공공정책을 신속하게 추진할 수 있었다. 또한 시장의 교체에도 불구하고 누비자가 지속되게 된 가장 결정적인 요인은 시장과 시정부가 누비자를 국내외적으로 적극적으로 홍보하였고 생태교통연맹 의장 도시 역할을 수행하는 등 누비자를 지원하는 다양한 활동을 병행하였으며 그 결과 누비자와 창원시가 국제적 명성과 관심을 받게 되어 정책에 있어서 일종의 '돌아갈 수 없는 지점'을 통과하였기 때문이다. 향후 누비자의 발전을 위해 누비자와 관련된 정책 과정에서 시정부 뿐 아니라 시 의회 및 시민사회의 다양한 행위자들의 보다 적극적인 역할이 수반되어야 한다.

  • The article compares economic and environmental performance of Taipei and Almaty from the point of view of "green" economy, which is able to act as a key tool to ensure sustainable development of the region. As the comparison of the parameters of ecological and economic development of the Taipei and Almaty cities shows, they are similar in population size, but demonstrate completely different trends of sustainable development. Economic performance of the Taipei city is achieved with a decrease in the consumption of natural resources and the production of pollution, while the situation in Almaty is the opposite. Almaty maintains a high level of air pollution due to the use of coal in electricity production, as well as increased traffic and density of construction, including the southern part of the city, which is a zone for the transit of mountain air flows. The article discusses the activities jointly conducted by the Government of Taiwan and non-governmental organizations on environmental issues, as well as environmental NGOs, which resulted in significant improvements in the environmental field. Measures to stimulate the development and implementation of environmental innovations applied in the field of sustainable development in the city of Taipei can be adapted for the city of Almaty, where the environmental situation deteriorates year by year.

  • Tabriz is a large Iranian city and the capital of the East Azerbaijan province. The bed rock of this city is mainly consisted of marl layers. Marl layers have some outcrops in the northern and eastern parts of city that mainly belong to the Baghmisheh formation. Based on their colors, these marls are classified into three types: yellow, green, and gray marls. The city is developing toward its eastern side wherein various civil projects are under construction including tunnels, underground excavation, and high-rise building. In this regard, the swelling behavior assessment of these marls is of critical importance. Also, in lightweight structures with foundation pressure less than swelling pressure, several problems such as walls cracking and jamming of door and windows may occur. In the present study, physical properties and swelling behavior of Baghmisheh marls are investigated. According to the X-ray diffractometer (XRD) results, the marls are mainly composed of Illite, Kaolinite, Montmorillonite, and Chloride minerals. Type and content of clay minerals and initial void ratio have a decisive role in swelling behavior of these marls. The swelling potential of these marls was investigated using one-dimensional odometer apparatus under stress level up to 10 kPa. The results showed that yellow marls have high swelling potential and expansibility compared to the other marls. In addition, green and gray marls showed intermediate and low swelling potential and swelling pressure, respectively.

  • The study aims to investigate the antecedents affecting purchase intention in the category of green skincare products. Many studies have used the theory of planned behavior to investigate factors affecting intention to purchase products in general. This paper not only retests the influences of attitude, subjective norm, perceived behavioral control on the intention to buy eco-friendly skincare products but also suggests a new antecedent - environment knowledge of purchase intention. More importantly, this study is the first to propose the moderating effect of country of origin and product knowledge on the relationship between attitude and purchase intention. This study employs a sample of 350 female customers from 18 to 39 years old in Ho Chi Minh City. The research applies the Multiple Linear Regression to analyze the proposed hypotheses in the conceptual framework and results in significant outcomes. The result shows that attitude is the most influential factor then, subjective norm, perceived behavioral control and environmental knowledge. Most importantly, the findings of this study suggest that product knowledge is found to moderate the effect of attitude on purchase intention. The finding of moderating effect is a new contribution to the literature and future research can be carried out to validate this result.

  • 도시공원법이 개정됨에 따라 도시계획 및 토지이용과 연계하여 장기적이고 체계적인 공원녹지 확보 및 관리를 위한 방안 마련이 시급한 상황이다. 이에 본 연구는 GIA 개념도입을 통해 생태적으로 중요한 동시에 훼손 가능성이 높은 지역을 추출하는 방법을 제안하고 이를 대전광역시에 적용하여 공원녹지 네트워크 구축을 위한 기초자료로 제공함을 목적으로 하고 있다. 본 연구는 문헌연구를 통해 GIA의 개념 및 분석과정을 도출하고 이를 대전광역시에 적용하여 생태적으로 중요한 지역이면서 동시에 개발위험도가 높은 지역을 규명하고 이를 중점관리지역으로 도출할 수 있었다. 본 연구를 통한 시사점은 공원녹지기본계획을 수립함에 있어 GIA 개념의 도입을 통해 도시계획과정과의 연계성을 높일 수 있을 뿐 아니라 객관적이고 설득력 있는 자료를 제시할 수 있다는 것이고, 또한 공원녹지 보전의 우선순위 및 관리방안을 제시할 수 있다는 점이다. 그러나 본 연구는 사례지역이 한정되어 있고, 국외에서 구축된 자료와 국내 자료와의 상충문제, 스케일 상의 문제 등에 있어 그 한계를 보이고 있다. 향후의 연구는 이러한 점을 극복하여 보다 더 일반적인 상황에서 적용할 수 있는 계획프로세스 및 지표 선정 연구가 필요할 것으로 판단된다.

  • 최근 도시에서 생산되는 수많은 디지털 데이터를 저장, 운용, 분석하기 위한 3차원 도시 공간정보 인프라에 대한 수요가 증가하고 있다. CityGML은 OGC (Open Geospatial Consortium)의 3차원 공간정보 데이터 표준으로서 도시 데이터의 교환 및 속성 표현에 강점을 가지고 있으며, 최근 싱가폴, 뉴욕 등 몇몇 도시를 중심으로 CityGML 형식의 3차원 도시공간 데이터를 구축한 사례가 등장하였다. 그러나 현재 CityGML 데이터의 제작 및 편집을 위한 생태계는 sketchup이나 3d max 등 3차원 데이터 구축에 활용되고 있는 상용프로그램과 비교할 때 완성도가 부족하여 대규모로 CityGML 데이터를 구축하는 데 한계가 있다. 따라서 본 연구에서는 항공 LiDAR (Light Detection and Ranging) 나 RGB (Red Green Blue) 카메라를 이용하여 신속하고 자동으로 제작되는 3D mesh 데이터 및 2차원 폴리곤을 활용하여 3차원 공간정보 표준인 CityGML 데이터를 구축하는 방법을 제시하였다. 데이터 구축과정에서는 각 객체가 다양한 CityGML LoD (Level of Detail)로 표현될 수 있도록 원본 3D mesh 데이터를 변형하였고 공간정보로서 활용도를 높이기 위해 2차원 공간정보 데이터로부터 추출한 속성정보를 보조적으로 활용하였다. 본 연구에서 제작한 도시 3D 객체는 CityGML 건물, 교량, 도시시설물, 도로, 터널이며 객체별 데이터 변환, 속성 구축 방법을 제시하고 가시화 및 유효성 검정을 진행하였다.

  • Since most Green House Gases (GHGs) and air pollutants are generated from the same sources, it will be cost-effective to develop a GHGs reduction plan in combination with simultaneous removal of air pollutants. However, effects on air pollutants reduction according to implementing any GHG abatement plans have been rarely studied. Reflecting simultaneous removal of air pollutants along with the GHGs emission reduction, this study investigated relative cost effectiveness among GHGs reduction action plans in Busan Metropolitan City. We employed the Data Envelopment Analysis (DEA), a methodology that evaluates relative efficiency of decision-making units (DMUs) producing multiple outputs with multiple inputs, for the investigation. Assigning each GHGs reduction action plan to a DMU, implementation cost of each GHGs reduction action plan to an input, and reduction potential of GHGs and air pollutants by each GHGs reduction action plan to an output, we calculated efficiency scores for each GHGs reduction action plan. When the simultaneous removal of air pollutants with the GHGs reduction were considered, green house supply-insulation improvement and intelligent transportation system (ITS) projects had high efficiency scores for cost-positive action plans. For cost-negative action plans, green start network formation and running, and daily car use control program had high efficiency scores. When only the GHGs reduction was considered, project priority orders based on efficiency scores were somewhat different from those when both the removal of air pollutants and GHGs reduction were considered at the same time. The expected action plan priority difference is attributed to great difference of air pollutants reduction potential according to types of energy sources to be reduced.

  • Due to the Climate change and resource shortage by global warming, various problems are rising and getting worse around the world. Many countries are doing the considerable efforts to reduce greenhouse gas emissions. The government of South Korea also plans to decrease greenhouse gas emission, the various pilot projects are underway, which includes obligation of energy efficiency 1st rating and greenhouse gas target management system of public buildings. In particular, luxurious government office buildings and energy-wasting public building have issued and emerged as a social problem. Energy efficiency improvement of the existing public office buildings are becoming an important issue recently. This study is proposed the step-by-step energy improvement model according to the building energy efficiency rate in order to reduce the energy consumption. To attain this end, I set up a base model by analyzing the current architectural conditions of the existing public office buildings and grasped the specific properties of building energy consumption through energy simulations. Furthermore, I suggested phased reduction prototypes for the reduction target of energy consumption by applying the methods of the zero energy building plan. This study is expecting that prototypes would give directions when it comes to planning the implementation policy of phased building plan factors, according the building energy consumption reduction goal in the existing public office buildings which are the subject of building energy target management system.
