  • Alkali-activated slag concretes are being extensively researched because of its potential sustainability-related benefits. For such concretes to be implemented in large scale concrete applications such as infrastructural and building elements, it is essential to understand its early and long-term performance characteristics vis-a'-vis conventional ordinary portland cement (OPC) based concretes. This paper presents a comprehensive study of the property and performance features including early-age isothermal calorimetric response, compressive strength development with time, microstructural features such as the pore volume and representative pore size, and accelerated chloride transport resistance of OPC and alkali-activated binder systems. Slag mixtures activated using sodium silicate solution ($SiO_2$-to-$Na_2O$ ratio or $M_s$ of 1-2) to provide a total alkalinity of 0.05 ($Na_2O$-to-binder ratio) are compared with OPC mixtures with and without partial cement replacement with Class F fly ash (20 % by mass) or silica fume (6 % by mass). Major similarities are noted between these binder systems for: (1) calorimetric response with respect to the presence of features even though the locations and peaks vary based on $M_s$, (2) compressive strength and its development, (3) total porosity and pore size, and (4) rapid chloride permeability and non-steady state migration coefficients. Moreover, electrical impedance based circuit models are used to bring out the microstructural features (resistance of the connected pores, and capacitances of the solid phase and pore-solid interface) that are similar in conventional OPC and alkali-activated slag concretes. This study thus demonstrates that performance-equivalent alkali-activated slag systems that are more sustainable from energy and environmental standpoints can be proportioned.

  • The purpose of this study is to examine middle school students' environmental worldviews, focusing on the following: 'Technocentric (TC)', 'Ecocentric (EC)', and 'Sustainable Development (SD)' environmental worldviews. The instrument surveying the worldviews of middle school students comprised two components: 'natural environment' and 'human action & environment'. The 'natural environment' component consisted of four categories. These were the value of humans in nature, the value of natural environments, nature reigned by humans, and the equilibrium sustaining power of environmental ecosystems. The 'human action & environment' component also consisted of four categories. These were the depletion of energy & resources, technology development, economic growth, and the severity of environmental problems. The subjects were 376 middle school students (152 males and 224 females), who were selected from 10 middle schools, and they answered question items by themselves through an online survey system. They displayed more 'Sustainable Development environmental worldviews' and 'Ecocentric environmental worldviews' than 'Technocentric environmental worldviews'. Furthermore, the female students displayed more 'Sustainable Development environmental worldviews' than the males. Hence, it is necessary to implement educational approaches that address and relate to the sustainable development environmental worldviews of middle school students.

  • The purpose of this study is to investigate the planning of the community spaces for sustainable apartment complex under the aging society. For this, it is needed to identify the practical meaning of community spaces for elderly residents. In many cases, existing apartments' community spaces have been designed without considering the elderly. In order to develop successful environment for aging society, it is necessary for us to precisely review how elderly residents are changing their needs. Survey and depth-interview methods were used for data collection of this study. This study was performed in the five subject apartments located in Haeundae new town, Busan. In planning of community spaces for sustainable apartment complex in the aging society, 1) The population of the elderly in apartment complex has been increased with progress of the aging society, and it has been necessary to enlarge and consider the aging-friendly community space. 2) When the community space is located in a good accessibility, visual openness, multipurpose composition and the center of complex, it was investigated that the degree of its usage was high. 3) Common apartment complex for the elderly was deficient, and the composition and the layout of community spaces were needed, which included sports facility, spaces for leisure culture and study. This study could be utilized as basic data for designing community spaces in apartments from the perspective of sustainable community.

  • The question of how to establish sustainable agricultural systems has become as prominent as questions related to water, energy and climate change. High input/high output agriculture has brought with it many adverse effects; the massive deterioration of soil and water in both quantity and quality, increased greenhouse gas emissions and an increased prevalence of unsafe foods. Additionally, urbanization and climate change has worsened the shortage of farmland and reduced the supply of agricultural water. Given these challenges, maintaining, conserving and efficiently using agri-environmental resources, through fostering of sustainable agriculture, have emerged as key tasks in solving these problems. What is needed therefore is research, based on systematic and comprehensive empirical analyses, that can propose plans and methods for establishing an appropriate sustainable agricultural system. The empirical analysis of sustainable agricultural system is approached separately from economic, environmental and social aspects. An analysis of environment effect reveals that the available phosphate level is 1.3~2.1 times greater than the optimal amount in rice paddies, upland fields and orchards. Further examination has revealed that the excess nutrient is polluting both ground water and surface water. Analytical results for economic feasibility show that factors of production have been invested heavily in the rice crop. Under these conditions, sustainable agriculture, including low-input agriculture, appears to be a possible alternative that will facilitate simultaneous improvements in both economic feasibility and environment effects. Analysis results for sociality reveal that social factors include the value of producer, association and interior networks. Social conditions are comprised of leadership, consumers' awareness, education and conflict solutions. In addition, analysis as to the degree investments contribute to improving agricultural value added has revealed that the direct payment program is the most effective instrument. Experts confirm that economic feasibility can be improved by scientific and well-reasoned nutrient management on the basis of soil testing. Farmers pointed to 'economic factors' as being the largest obstacle to switching to the practice of sustainable agriculture. They also indicate 'uncertainty with regards to sustainable agriculture technology' as an impediment to practicing sustainable agriculture. Even so, farmers who believe environmental and regional issues to be the most pressing problems have expanded their practice of sustainable agriculture. The keys to establishing sustainable agriculture system are classified into the following four aspects. Firstly, from an economic aspect, the research indicates that agricultural policy needs to be integrated with environmental policy and that the function of market making based on the value chain needs to be revitalized. Secondly, from an environmental aspect, there is a need for an optimal resource management system to be established in the agricultural sector. In addition, sustainable agriculture practice will need to be extended with attendant environmentally-friendly and sustainable intensive technology also requiring further development. Thirdly, from a social aspect, green agriculture management needs to be fostered, technology and education extended, and social conflict mediated. Lastly, from a governance aspect, it will be necessary to strengthen good governance, assign and share suitable roles and responsibilities, build a cooperation system and utilize community supported agriculture.
