The purpose of this study is to examine residents' consciousness for urban parks and green spaces in the city of Daejeon. This work enables us to find new implementation factors to increase resident's satisfaction of urban parks and green spaces. This study surveyed 1005 residents from 80dongs(neighborhoods), of 5 Gu(districts) districts in Daejeon. The survey was conducted with a structurally organized questionnaire and objective materials. The data collected from participants of the survey were summarized as follows. Daejeon residents want more natural parks and neighborhood parks than other urban facilities as recreation facilities. The favorite places in which Daejeon residents visit are Bomun Mountain, Gap River, Geajock Mountain, and Yudeon River, in order. In landscape scenery of Daejeon, residents prefer Daedeck research complex area than others and they felt that urban landscape scenery is more improved than 5 years ago. Also they want to increase the area of park and green space about 4times more than present. The result shows that the importance index of park and green space is 8.7 and the satisfaction index is 5.42. These results suggests that the demand by residents for urban park and green spaces will improve as the urban structure is improved.

The continuing trend of built environment set forth by the rise of modernization and industrialization has led every country in achieving their respective economic development. Along side this trend is an issue that needs to be addressed - the environmental impacts of the built industry. Construction and maintenance of buildings are said to consume 40% of the world's energy, 65% of electricity, and 40% of raw materials, creating drastic pollutants harmful not only to the environment but also to human. Figures have been released and analyzed proving the contributions of built environment with environmental depreciation. Said figures earned concerns not just from different private and non-profit organizations but also the governments of every country, thus, steps towards sustainable development are being implemented. As a response, the "green" was added in the built environment. Later on, the now emerging concept of "National Green Building Code" found its role in the policy of various states in protecting the people in accord with the nature. This paper appreciates the initiatives of various countries and non-profit organizations in their drive to pursue sustainable green built environment in general, and specifically proposes an establishment of an "incentives grant framework" as an additional legislative policy to be included in the draft of the National Green Building Code of the Philippines.

In this study, eco-friendly hybrid composite boards were manufactured from green tea, three kinds of charcoals and wood fiber for developing interior materials to reinforce the strength performances and the functionalities in addition to performances of the green tea-wood fiber hybrid boards. The effects for the kind and the component ratio of raw materials on mechanical properties were investigated. Bending strength performances of hybrid composite boards were highest in the hybrid composite boards composed of green tea, fine charcoal and wood fiber on average. However, the difference caused by the kind of charcoals was not large. These values were was markedly improved than those of green tea - wood fiber hybrid composite boards reported in previous researches. And it was found that the bending strength performance decreased with increasing component ratios of green tea and charcoals. The difference between urea resins used as the binder showed the higher value in hybrid composite boards using $E_1$ grade urea resin than in those using $E_0$ grade urea resin, but the difference between hybrid composite boards manufactured by both resins decreased markedly than the green tea - wood fiber hybrid composite boards reported in previous research. The internal bond strength of hybrid composite boards was in the order of hybrid composite boards with fine charcoal, activated charcoal and black charcoal, and it was found that the hybrid composite boards with fine charcoal had a similar values to control boards composed of only wood fiber.
