The Heat Island phenomenon has defined that indicated a more high temperature than suburb owing to high density of population and buildings, etc. This study is focused on basic implements the distribution of temperature and wind speed under Heat Island phenomenon in city. in order to analysing using data were statistically analysed by AWS data in Busan. In Sequence, through practical use spatial analysis software is expressed distribution of temperature and wind speed by local area and season. As a result, temperature and wind speed dispersion is affected by topographic condition, the mountains, sea, etc. We should be examine relationship of the density of buildings and temperature, The height of buildings and win speed using exact observation and statistical analysis.

Analysis of Creep Behavior of Alloy 617 for VHTR Application
Woo-Gon Kim(김우곤), Jae-Young Park(박재영), I.M.W. Ekaputra Min-Hwan Kim(김민환), Seon-Jin Kim(김선진), Yong Wan Kim(김용완) 대한기계학회 2013 대한기계학회 춘추학술대회 Vol.2013 No.12
Creep rupture data were obtained from a series of creep tests with different applied stresses at 850℃, 900℃ and 950℃ of Alloy 617, which is considered as a prime candidate material for the VHTR application. On the basis of the creep experimental data, the analysis of creep rupture behavior was performed using various creep relations and laws such as Norton's power law, Monkman-Grant Relationships (MGR), Modified Monkman-Grant Relationships (MMGR), creep damage tolerance factor λ, and Zener-Hollomon Parameter (Z), and then the creep constants used in these equations were determined. The MMGR appeared to be more narrowed in data scattering than the MGR, and it followed well a straight line of m ? 1.0 as m=0.97. In the plot of the Z parameter vs. stress, it obeyed a straight line of the slope of n'=5.87 regardless of the three different temperatures. It would be thus inferred that the same creep mechanism was operative within the present stress and temperature ranges, and creep damage tolerance factor of Alloy 617 was found to be 2.40.

In this paper, it was described the current technology status of bearingless rotor hub system for helicopter which is one of major rotor hub system. Also, a conceptual study on the new bearingless rotor hub system of helicopter was described. First, the advantages and disadvantages of major helicopter rotor hub system are described in comparison to each other types of rotor hub system. The unique characteristics of bearingless rotor hub system are described compared to other types of rotor hub systems. Next, the main function, role and characteristics of the sub-components of bearingless rotor hub system are described. Recent helicopters which adopt this bearingless rotor hub system are described and introduced. This conceptual study shows that double-H sectional construction and rectangular construction of flexbeam are the most effective candidates of this new bearingless rotor system. This bearingless rotor hub system can be used for 7,000lbs class helicopter. Now, a further trade-off study will show.
