BIM technology has been introduced in various fields of the construction industry recently. The owners of the public construction projects are already interested in BIM technology and they started to apply BIM technology in their projects. This paper introduces the successful BIM cases of overseas and domestics projects and shows how to introduce and apply BIM technology in the architectural design firms and construction companies and how to train their engineers with BIM technology.

A general practice in software ordering behavior in public sector has been an enormous obstacle standing in development path of Korea's software industry. Standard on software development cost estimation is supposedly based on Function Point, but in general, it is on headcounting (a number of people involved in a project). Moreover, it is difficult to change a contract in an on-going project, since statement of work is not precisely and carefully described. But it has a simple solution. Design and Implementation should be a separate project, as in construction industry, and both power and responsibility for design should be given to an expert with a national-level qualification. Here, there is a simple way for Korea to reborn as one of the strongest software country.

This project located in IFEZ(Incheon Free Economic Zone) is the first central heating and cooling type for high-rise residential building in korea. The design was performed as the joint venture between Cosentini from U.S.A and wooowon, and our design concept was to save energy. LEED application from USGBC is going on in progress for the first residential building in korea. Careful attention was paid from schematic design for not a durability of structural and architectural, but also durability and safety of M.E.P.

Engineered nanoparticles are materials purposefully produced with at least one dimension between 1 and 100 nanometers. Nanotechnology has the potential to dramatically improve the effectiveness of a number of existing consumer and industrial products and could have a substantial impact on the development of new products in all sectors. However, nanoparticles is little known about what effect these properties may have on human health. This materials provide an overview of what is known about the potential hazards of engineered nanoparticles and measures that can be taken to minimize workplace exposures.

The last century of lighting has been dominated by incandescent, fluorescent and high-intensity discharge(HID)light sources. In the late 1970's, after green LEDs were invented, Dr. Ching Tang at Eastman Kodak discovered that sending an electrical impulse through carbon compound caused such material glow. Present day LED commercial packages have reached 100 lm/W, comparable to the efficacies of fluorescent and certain HID lamps. LED products available today are market as "Green-Industry" but actually low light output compared to typical light sources. The combination of high price and low light output make them a poor replacement for current technology. It is very important to compare new LED products to the most efficient conventional technology that could be used for any specific application. As LED technology advances, costs decrease, and efficiency improves, LEDs will build market share in the general illumination market.

Many companies are looking for going into the LED Industry as LED has the brightest prospects in the future compare to any other industries. But many companies are lack of comprehension of market for successful entry decision. It is highly recommended to setup the effective strategy by categorizing the LED application markets and selecting the target market. In this paper LED Lighting industry is mainly explained among the many LED markets.

The new method to improve pine-fungi activity are needed by customed forest tending. Fungi is essencial for human life. Pine-mushroom (Trichroma matsutake)products are related to fungi activity. These are improved by customed forest tending. For example, species arrangement, thinning ratio, light control, water supply etc.
