Abstract: This research evaluates the spatial distribution of thermal comfort in residential gardens using geostatistics; a residential garden in Taichung City was studied. The monitoring sites were systematically equipped to record the physical environment factors used to monitor and calculate the Physiologically Equivalent Temperature (PET), which was used to estimate the spatial distribution according to the Kriging Method. The research findings showed that users perceived comfort or slight warmth in the studied region, and the spatial distribution of the PET appeared at diverse times and spatial variability characteristics. In other words, the users perceived comfort at distinct locations in different time periods. At noon (11 am - 2 pm), the right and left side areas of the garden were considered to be more comfortable, while the right area was perceived as more comfortable in the afternoon (2 pm - 5 pm), the times in which sunshine and shadow were considered to be the major factors. The research results also show that waterscapes and plants could reduce the temperature and enhance thermal comfort in the garden.

Abstract: This work presents a numerical study on airflow and particle dispersion within an urban street canyon with different wedge-shaped roof. A two-dimensional computational fluid dynamics (CFD) model for evaluating the airflow and particles dispersion within a street canyon was built up, which was based on the incompressible Reynolds Averaged Navier-Stokes equations, turbulence model and the particles transportation equation. It is revealed that: (1) particles dispersion inside an urban street canyon is mostly dominated by the in-canyon wind flow; (2) different wedge-shaped roof configurations causes a variety of particles distribution patterns; (3) air pollution levels are much higher in the step-down canyons relative to the step-up canyons; (4) the simulated result of FLUENT is reasonable, and the prospect of applying FLUENT to study atmospheric environment is very well. Key words: CFD; street canyon; particle dispersion; numerical simulation

Abstract: With the impact of global climate change, how should the concept of low-carbon ecological city be implemented in urban planning practice has become a critical issue challenging decision-makers and planners. This issue is particularly important for the fast-growing regions in China which has experienced rapid urbanization and an increase in carbon emission. In view of these problems, this study uses the Shenzhen city, an extremely fast-growing city in China, as an empirical case setting to address this issue. A systematic approach that integrates research methods including literature review, case studies, field survey, and stakeholder-based interviews was employed. Through our research investigation, a comprehensive low-carbon ecological city planning framework was developed. Several selected planning strategies that address the key elements of the framework were also suggested.

Abstract: Path dependence is a universal problem in the transformation of resource-based cities that lead to fall into hold-up dilemma, lost perfect chance to transform, and pay more cost. This paper offered a model of resource-based cities life cycle that revealed the general transformation path that emphasized the key booming period, analyzed equilibrium of traditional resource industry and alternative industry that discloses the mechanism why the transformation of resource-based cities delayed until the recession period came, and suggested that the government of resource city can play important role in process of transformation through a model of entry barrier of new alternative industry.

Abstract: The rapid development of information and communication technology (ICT) and the Internet have accelerated the transformation of social patterns and lifestyles. Intelligent technology services have become indispensable to peoples daily lives in the twenty-first century. In Taiwan, the 921 earthquake in 1999 and Typhoon Morakot highlighted the significance of safety and disaster prevention in rural communities. Implementing intelligent living technology in rural communities can enhance residents knowledge and concepts of disaster prevention, relief, and evacuation, and prevent losses from disasters. Considering the rapid development of global ICT and the threat and pressure of natural disasters and deteriorating living environments, we used the evaluation framework for low-carbon rural communities developed in a preliminary study as a foundation and introduced intelligent living applied services and technology. Through this study, we hoped to enhance the competitiveness of rural communities by adjusting industrial policies and the living standards in rural communities according to the lowest costs and the highest efficiency. The results showed that the sustainable evaluation indicators do have positive benefits for rural communities, consistent with our review of literature. Intelligent living technology exhibits a positive significant impact on development potential evaluation of rural communities, a result consistent with the results of related domestic and foreign studies. Therefore, governments can strengthen the quality of life benefits brought by intelligent living technology, such as effective microclimate environment adjustments, creation of good leisure spaces and scenery, and improvements to the basic production conditions, preservation of the rural ecology and culture.

Abstract: With the growth with the citys population of elderly people, the symptoms of aging are becoming more and more significant. Older people are faced with complex circumstances when they are outdoors, a correct and efficient system of road signs should help them reach their destinations safely. Therefore, a well designed system for the elderly is vital. The following research is concentrated on the design of the road sign system focusing upon the aspects of placement positions, height of the text and symbols, and the amount of information included on the sign. This will assist in the design of the most useful and efficient sign board system for the elderly. This will be determined through the experimental method.
