With the booming of construction and property industries in China, the demand for high-rises and mega-scale buildings with more integrated building functions, open- and tailor-shaped outlooks, better connections to municipal infrastructures, and higher grades of building importance has been increasing in the past two decades. The seismic design and engineering of such modern mega-buildings face engineering challenges such as hazard mitigation of extreme actions and surroundings, integrated structural frameworks and building skins, complex connections, and overall construction efficiency. It is the work of a new generation of civil and structural engineers to enhance engineering efficiency and achieve overall engineering, environmental, and economical effectiveness for these high-rise projects. This paper elaborates the above topics through case studies on the design and construction of four such developments in China. Some rethinking is conducted on evolution in modern seismic engineering and design through innovation to achieve an acceptable level of overall sustainability and building effectiveness.

Buildings, energy and the environment are key issues that the building professions and energy policy makers have to address, especially in the context of sustainable development. With more tall buildings constructed in China, the impact on energy consumption and carbon emission would be great from buildings (2% increase of carbon dioxide annually between 1971 and 2004). The imperative was to investigate the building energy performance of high-rise in different climate zones and identify the key design parameters that impose significantly influence on energy performance in sustainable building design. Design implications on glazing performance, sizing of the ventilation fans, renewable energy application on high-rise building design are addressed. Combination of effective sustainable building design strategies (e.g., building envelope improvement, daylight harvesting, advanced lighting design, displacement ventilation, chilled ceiling etc.) could contribute more than 25% of the total building energy consumption compared to the international building energy code.

Background and objective: This study was conducted to obtain empirical data for deriving necessary items for the creation and management of gardens in urban agricultural parks while maintaining the publicness of the place by examining the difference in perception among park visitors about the gardens in the public parks. Methods: A survey was conducted on users of urban agricultural parks in 6 locations and 113 copies of the questionnaire were collected. After understanding the demographic characteristics and the current use of the garden, we identified the importance of the necessary items for the public gardens. Results: 108 subjects(95.6%) responded that gardens are needed in urban parks, for psychological and emotional health (26.2%) and for interaction and friendship with family and neighbors(23.2%). For use of garden crops, most were private sales(96 subjects, 64.4%), and both sales preferred to partially donate their crops. Most used communal gardens operated by public institutions(30.1%). It was found that 96.4% of the respondents were satisfied with gardening activities, and 107(94.7%) of them showed their intention to participate in the gardening in the future. The Kaiser Meyer Olkin value was .848 and the significance level was .001, proving the validity of factor analysis. The factors were named composition elements(Factor 1), management items(Factor 2), convenience elements(Factor 3), and operational facilities(Factor 4). In the survey on the creation and management of gardens in urban agricultural parks, there were no statistically significant differences, but all items had correlations. Conclusion: The results have reflected the needs of actual users in establishing the plans to operate urban gardens, thereby having great utility value as the basic data for continuous garden management. Further research can be conducted to derive detailed elements that can guarantee sustainability of urban gardens and suggest high-quality data for management of gardens in urban agricultural parks.

This paper discusses how the strategies for crime prevention are interrelated to sustainable urban development. The sustainable urban development for healthy and safe cities implies regulations or legal, lawful control to reduce fear of crime and prevent substantial threats to health and safety of individual persons as well as of the community. City planners attempt to apply to the strategies for crime prevention their perception of what the sustainable urban development should be with respect to urban environment. Many planners have studied on the possibility of reduction in fear of crime and actual crimes through environmental improvement. The results of their preliminary studies provide specific suggestions to reduce crimes and fear of crime by application of CPTED. This study proposes alternatives in policy necessary for CPTED, which is one of the strategies for crime prevention, to take its place as a useful strategy for making the urban societies safe and sustainable.

Official development assistance (ODA) projects are conducted under the auspices of donor countries and on the principle of time-limited implementation for economic development and welfare improvement in a host country. Exit strategies on how to end official assistance are therefore crucial. Sudden economic recession in a donor country could lead to the suspension of ODA projects, which would affect diplomatic relations and project outcomes. Further, exit strategies can help continue the original project and create links with other ODA projects. This study shows how to employ exit strategies in the Korea-Mongolia Greenbelt Plantation Project and has implications for sustainability of development assistance. Exist strategies were not taken into consideration initially. In the course of implementation and management transfer upon the completion of plantation, various facets were considered later on in developing exit strategies. An ideal exit strategy is to reach the extent to which a host country no longer needs official assistance or has capacity of project implementation on its own. A year-by-year transfer of planted areas can be a phase-over strategy. The Korea Forest Service fulfilled transparent cooperation with Mongolian local governments, established appropriate arrangements with stakeholders, secured institutional and financial foundation for follow-up management by a host country, and realized predictability, responsibility, and sustainability. As a local institution, the plantation technology management center has been established for follow-up activities such as the introduction of agro-forestry. When the Korea Forest Service designed an urban forest project as an exit strategy, sustainability was ensured, which has implications in implementing other ODA projects.

The design principles of new urbanism (NU) have been adopted for new towns-in town projects for inner city neighborhoods in Seoul, Korea Since 2000. Here, ten NU principles were matched to four urban design categories: streets, land use, housing and buildings, and public open spaces. These elements were analyzed for Eunpyung New Town project. Through the case, the applications and implications NU principles are explored. The principles of connectivity, quality architecture and urban design, increased density, green transportation, sustainability, and quality of life were positively and successively adopted for streets, land use, housing and buildings, and public open spaces. The principles of mixed-use and diversity and traditional neighborhood structure were only partially applied in land use, housing and buildings, and public open spaces. It should be note that the walkability principle is intended not for job-housing proximity, but for pedestrian-friendly street design.

Smart city has effect toward its sustainability. Citizens should be viewed as co-creators of cities, not consumers. From this point of view, citizen responsibility and ethics should be emphasized. Now, Smart cities are becoming more important than ever. From now on, urban development is divided into two major categories. One side is the development based on smart city, and the other is urban development that revives the old city. As the city grows bigger and bigger, many problems arise and there are many problems. This tendency must become stronger in the future. But, Stones shall be dressed to exact size and shapes before being laid. Until now, No attempt has been made to declare about Citizen Spirit in Fourth Industrial Revolution. In the era of the Fourth Industrial Revolution, in order to become a leading country of Smart City, we must first complete the spiritual revolution. From this aspect, this study proposes the "Declaration of the Fourth Industrial Spirit Revolution".

Urbanization and industrialization associated with rapid economic development have resulted in air pollution in urban areas, which adversely affects human health and the environment around the world. Growing awareness of the health effects of airborne particulate matter (PM) has led to the emergence of urban greening as a promising eco-friendly, nature-based solution to reduce the concentration of PM (especially PM_2.5) to which individuals are exposed, thereby promoting public health. In this review, we highlight fundamental insights about PM and recent research on the ability of urban greening to capture PM. Reports from the scientific literature on PM published from 1992 to 2021 were retrieved from Google Scholar. Here, we explore some of the main complex relationships between leaf traits and the ability to retain PM for research or management to optimize greenspaces.
