This study examines the characteristics of Korean venture businesses and proposes some policies for promoting them. For these purposes, a broad survey was conducted of 203 venture businesses in April 1997. The survey shows that Korean venture businesses are characterized by their small size, independence, newness in age, intensity of knowledge and technology, and fast growth and willingness to take risks. To foster venture businesses in Korea, the following strategies are proposed at the policy level. First, it is necessary to strengthen the foundation for developing technology. Second, venture capital must be expanded more than ever. Third, stock markets need to be activated so that many venture businesses can be listed and raise funds. In this respect, the Kosdaq stock market must transform into one which can compete with the Korean Stock Exchange, just as the Nasdaq stock market competes with NYSE in the U.S. Fourth, various locational aids need to be provided to venture businesses in order that the conglomeration effects hold.

We investigate the indoor flow characteristics of cubical and rectangular bodies(150<SUP>d</SUP>×150<SUP>w</SUP>×150<SUP>h</SUP>, 150<SUP>d</SUP>×300<SUP>w</SUP>×150<SUP>h</SUP>, 150<SUP>d</SUP>×450<SUP>w</SUP>×150<SUP>h</SUP>) placed in a deep turbulent boundary layer. The study undertakes measurements of internal pressure distribution when changing the angle - 0°, 15°, 30° and 45°. The experiments are carried out at two different Reynolds number, based on the wind velocity U (4.5㎧, 7.3㎧) at the body height h, of 4.6×10⁴, 6.7×10⁴.
