  • With the purpose of long-range planning toward local/regional sustainable development, it is desired to avoid unconditional industrialization and expansion and to build an eco-oriented development strategy considering site-specific characteristics of the environment. This paper thus aims at the elaboration of a system dynamics model of a locality/region so as to understand inherent dynamics of sustainable development and to assess the effectiveness of such an eco-oriented strategy. The model thus consists of several positive and negative feedback loops that accelerate or restrict local/regional economic growth within a system boundary incorporating the environment, economy, and society. The model is moreover applied to the assessment of the effectiveness of the development plan recently established in Damyang in JeollaNamdo, Korea. It is regarded in this case to be effective for population immigration and economic prosperity to give priority to restore the bamboo ecosystem and nourish a series of eco-friendly industries based on the bamboo items developed recently. It is also to be positive to sustainable development since it enables to maintain high quality of the environment from the outset of their development steps.

  • This study aims at proposing a sound and sustainable development direction of an residential environment by analyzing testimonies of residents who lived in Park Hill flats or their surround at Sheffield City in the United Kingdom. The results are obtained through the analysis on a residential environment of Park Hill flats, opinions of the residents on its refurbishment, and effects of the building on the residential environment. The block of Park Hill flats was a community with a strong unity and solidarity, but that became increasingly a slum by the decline of the physical and social environment since the 1980s. In particular, it was identified that the deterioration of the social environment than that of the physical environment was a major cause of the decline. Nevertheless, it was found that "streets in the sky", the concept applied in Park Hill, played a key role in activating the community in the apartment complex. However, that street system in the complex has caused noise, poor security, and invasion of privacy. If such problems are solved, the streets in the sky will be a meaningful alternative for community activation and then ensuring sustainability in Korean residential environments that lost the function of the community.

  • Solar cells, converting abundant solar energy into electrical energy, are considered crucial for sustainable energy generation. Recent advancements focus on nanoparticle-enhanced solar cells to overcome limitations and improve efficiency. These cells offer two potential efficiency enhancements. Firstly, plasmonic effects through nanoparticles can improve optical performance by enhancing absorption. Secondly, nanoparticles can improve charge transport and reduce recombination losses, enhancing electrical performance. However, factors like nanoparticle size, placement, and solar cell structure influence the overall performance. This study evaluates the performance of silver nanoparticles incorporated in a p-i-n structure of perovskite solar cells, generated via aerosol state by the evaporation and condensation system. The silver nanoparticles deposited between the hole transport layer and transparent electrode form nanoparticle embedded transport layer (NETL). The evaluation of the optoelectronic properties of perovskite devices using NETL demonstrates their potential for improving efficiency. The findings highlight the possibility of nanoparticle incorporation in perovskite solar cells, providing insights for sustainable energy generation.

  • Community design education has covered the worldview dimension of the collaborative courses for sustainability draws on the architectural expertise developed in a network of community projects and therefore case studies of design education by the collaborative project-based learning in terms of participants, students, teachers and architects, such as 'Learning By Design' for the K-12 comprehensive program in Massachusetts addresses how a local society can make its community sustainable by both design and education. To understand that community design and education can provide professional development in all levels of skills and knowledge across disciplines and opportunities for collaborative learning and problem-solving, this research consists of case studies of the community design education including social systems that assist in organizing the local educational program as well as promoting the programs with public awareness of the community. It covers the UNESCO-UIA agenda of the community design and education that is to enhance the physical environment relating to human interaction by developing innovative alternatives of existing community and contributing voluntarily to neighborhoods through design. As the community design collaborative of design professionals and users is a structural approach to assess design quality, the cases address how to set up the architectural program in order to share pro bono design service and provide high-quality design resources available for sustainable environment.

  • A sustainable building must produce an interior environment that is safe, healthy, comfortable and supportive of human performance and well-being. The medical human comfort: performance and productivity cost of unhealthy environment may cause much cost for healing. Research that buildings with daylight, fresh air, eco-materials and sustainable interior design are consistently rated as more comfortable and occupants performance, satisfaction and health. This study is to categorize systematically interior environmental design elements for improving sustainability with a view to developing an evaluation model of super high-rise apartment unit plans. With a literature survey and design guide lines concerning sustainable design elements, three hierarchical categorization levels of human, environment, energy and resources systems that consists of upper, middle, low design elements have been proposed. A total of 6 items have been suggested for middle level of categorization and 24 items for lower level. Finally a total of 107 design elements concerning the 24 items and their relationahips have been revealed. The needs for a systematic approach to interior environmental design for sustainability have been discussed.

  • In this study, the membrane degassing process of the sweep gas - vacuum combination type was proposed for ammonia wastewater treatment. The effect of pH, initial ammonia concentration and scale-up on ammonia degassing performance was investigated. As a result, as the pH and the initial ammonia concentration increased, the degassing permeate flux was improved. On the other hand, the ammonia mass transfer coefficient increased as the initial ammonia reduced, which seems to be due to the driving force of the sweep gas-vacuum combination type membrane degassing system proposed in this study. In addition, 80 mg NH3/min of the ammonia degassing rate was achieved using a 6×28 inch size module. Better degassing performance is expected if consideration for maintaining vacuum pressure is involved in the scale-up design.
