  • The LED light source has many excellent advantages for the application of LCD backlight module. As we know, the operational temperature can significantly influence the characteristics of LEDs. Heat can damage the LED 's quality, and decrease its lifetime and output light intensity. In this paper, we perform computer software, Flomerics CFD (Computational Fluid Dynamics), to simulate heat distribution of the 20.1" LED backlight module we designing, and realize how the different heat sinks can solve the serious heat problem in practice.

  • Recently, the space organization of Korean-Chinese houses is different from that of other territories. The vast land of China, coming from different hometown in Korean peninsula, and the different hometown in Korean peninsula, and the different procedure of settlement seem to make the different space organization of Chinese-Korean single family housing at the urban area in Liaoning Province.The characteristics of the Korean-Chinese space organization of single family housing at the urban area in Liaoning Province are as follows;i)Three types of space organization are central kitchen type, central corridors types, and central living room type. ii)The central kitchen type is mainly in old urban housing, after 1980's, the central corridor type appears in single family housing, and central living room type appears 1990's.iii) It seems that the main reason to change the space organization are fuel, system of heating, influence of Korea housing. Especially, Korean-Chinese like central living room type that is suitable for sit down living style. This central living room type supposes to be used as popular space organization in urban housing.

  • In the present study, the effect of DW-1350, a newly synthesized anti-osteoporotic agent, was evaluated in ovariectomized Rat. Female SD Rat mice underwent bilateral ovariectomy for prevention study that test article was administered from 2 days after ovariectomy for 6 weeks, for therapeutic study it was conducted from 6 weeks after ovariectomy for three months.

  • The most common cause of death in fires is the inhalation of noxious gases rather than thermal injury. Carbon monoxide is well-known toxic component in fire atmospheres. However, the importance of hydrogen cyanide(HCN) as a toxic agent in the fire related fatalities(FRF) is under discussion. HCN is known to be produced in fires involving by the pyrolysis of polyacrylonitril (PAN) and other nitrogen-containing polymer. (omitted)
