  • In this study, we observed air temperature to make clear that land coverage condition and stand form has a certain relationship to air temperature during the night in various green space. And with revolution analysis, we interpreted relationship of air temperature distribution in the green space, The way of analysis is this land coverage rate and air temperature, of number of tree volume of tree air temperature. With this experimental result, we can propose green plan, which is taking into consideration lower effect of air temperature. In this result, lower zone is formed in forest and water area, higher zone is formed in paved surface and barren ground. but this gap is a little. arbor+subarbor area, in the point of water area surrounded stand is formed relative lower air temperature. As a result to make up efficiency lower air temperature area, it is needed to make water area which has surrounded forest, and it is needed to make stand form lower air temperature 2~3 layer forest. In order of arbor, subarbor, shrub, the lower air temperature is more effect.

  • This paper starts with a brief overview of the history of the European Space Agency and recalls some of its main features. Next, the gradual process of cooperation between ESA and the EU is outlined, leading to the creation of the Framework Agreement in 2004 and the adoption of the European Space Policy in 2007. The entry into force of the Lisbon Treaty in 2009 codified the space competence of the EU, and its implications are addressed. Lastly, some attention is paid to the issue of space security in Europe, through ESA's new SSA programme adopted in 2008, and to the relevance of the EU Council initiative for a Code of Conduct for Outer Space Activities in 2008. The paper ends with some conclusions.

  • PMV and ADPI were numerically investigated in a large space of various ceiling height with air-conditioning systems of two type. The numerical results showed that it is small that the growth of cooling load according to ceiling height rise in a large space without windows. In case of system air-conditioner of duct type embedded in the ceiling, the air mixing effect in indoor is superior to a case installed 4way cassette type in it. For controling thermal comfort at indoor, a system air-conditioner of duct type embedded in the ceiling is little influenced according to ceiling height rise in a large space considered.
