Ondol, Korean traditional heating system, has widely been used due to high thermal efficency based on its character of thermal dynamics. it has been also well known Ondol has improved real indoor thermal comfort compared to the other heating systems. Recently, a lot of numerical studies using CFD(Computational Fluid Dynamics) in order to understand interal thermal and flow field has been corned out. In present study, we find out the variation of temporal temperature in floor of traditional Goodie between Jul-Gorae and Doidon-Gorae, we have performed numerical analysis. According to flow rate streams, Weet-mok's temperature in a Doidon-Gorae is 7 t:: higher than Jul-Gorae 's. This asymmetry part has an influence on decreasing a standard deviation of the temperature.

A new malting barley variety, 'Daeabori', was developed from cross between Jinkwangbori/Milyang 46 and Mihogolden, a good quality, by the barley breeding team in the National Yeongnam Agricultural Experiment Station(NYAES) in 2001. An elite line, YMB1503-

A new wheat variety, 'Anbaekmil' was developed from the cross between Saemil and Geurumil by the wheat and barley breeding team of the National Yeongnam Agricultural Experiment Station (NYAES) in 2001. A promising line, YWM2078- 3B-2-3-7, was selected in

A new covered barley variety, 'Keunalbori 1' was developed from the cross between Keunalbori, a large grain variety, and Milyang 55, a brittle-awned variety, by the wheat and barley breeding team in the National Yeongnam Agricultural Experiment Station (N
