Anyang city performed a design competition for the existing paper mill site and this design is the work that was submitted to that competition. The design instructions for the competition were about an organic site which had harmony of aboveground park and underground parking lot, establishment of park planning which is fit for the features of nearby areas, and security of proper parking space. This design criteria set the design concept to a new wave of Anyang by reflecting the design instructions of prize contest and features of the site and developed it as three waves. First, the eco wave, one of three waves, means that it compose the ecological healthy park and urban environment together with restoration and preservation of Suamcheon (stream), and futhermore the waves that the natural resource are maintained in a delicate ecological balance as the water resource of Anyang city are connected to the axis of mountain resource. Secondly, the emotion wave indicates that the wave toward culture and art emotional park that stimulates and fills up the emotion to makes impoverishing modems minds fertile. Thirdly, the health wave means the waves toward a park to keep the sound of minds and bodies of Anyang citizens, and healthy and sound life as well as the waves toward a park to contribute the healthy leap and development of Anyang. These three waves will enrich the park keeping the dynamic relationship mutually and will be a new culture and art code of Anyang city.

With both Gatdui and Daean areas, under construction for upgrading the old housing in Gyeongju downtown area, this study was carried out to find out implications of upgrading methods in a historical and cultural city, by using a physical survey in the areas and life survey among their residents, as well as by analysing the level of their satisfaction with and requirement for housing and their preferring housing type. The upgrading patterns of residents were analysed by examining cases constructed newly in the manner of upgrading. The findings showed that it is required for both existing authorities and private parties to assume roles and responsibilities for upgrading the old housing while recently there have been continuous conflicts between development and preservation of the historic and cultural resources within the city and even the city identity also has been neglected by residents. In addition, it is necessary to take development conditions and resident's economic situation into consideration and introduce a wide range of methods for rearrangement, by turning the importance of housing upgrading to social rearrangement for the purpose of positive alternation.

The increasing industrialization of the world has led to precipitous rise for the demand of petroleum-based fuels. The world is presently confronted with the twin crises of fossil fuel depletion and environmental pollution. The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in the present. Bioenergy is playing an increasingly important role as an alternative and renewable source of energy. Use of Bioenergy has several potential environmental advantages. The most important perhaps is reduction in life cycle greenhouse gases emissions relatives petroleum fuels, since bioenergy is derived from plants which convert Carbon dioxide ($CO_{2}$) into Carbohydrates in their growth. Bioenergy includes solid biomass, biomas and liquid bio-fuels which are fuels derived from crop plants, and include biomass that's directly burned. The two most important bio liquid fuels today are bioethanol from fermenting grain, grass, straw or wood, and biodiesel from plant seed oil.

Understanding of routes of migratory birds are important subject for conservation of avifauna. Korea Demilitarized zone (DMZ) is considered as one of the most important stopover for migratory birds that pass in the Korean peninsula. This region has been known internationally as an excellent nature preservation areas since 1953. Rare and endangered animal species such as leopards (Pathera pardus) and Siberian tigers (Panthera tigris) have increased in population. Furthermore this areas provide home for endangered migratory birds including white-naped (Grus vipio) and red-crowned cranes (G. japonensis). Recent satellite-tracked crane species has shown the importance and linkages between a small number of habitat sites in DMZ. White-naped cranes were satellite tracked 9 individuals spent 27-78% of their time in Panmunjum and 10-75% in Cheolwon. This signifies the rich feeding sites with relatively little disturbance thus making the DMZ extremely valuable as a stopover.

At present, the cold cathode fluorescent lamp (CCFL) using mercury lamp has been generally used far liquid crystal backlight source of personal computer and car navigation and so on. This kind of lamp is more excellent on luminance performance and cost. However, the requirements of liquid crystal backlight due to a light source without mercury have been strongly increased from a viewpoint of the actual influence on environmental preservation and environmental recycling. As fluorescent lamp without mercury, Dielectric Barrier Discharge based rare gas fluorescent lamp (DBD-FL) using xenon (Xe) gas has been studied so far. This DBD lamp has no influence on the human body and environmental recycle. Its operating life is long because electrode is out. In this paper, the simulation and experimental results of soft switching high frequency inverter with reverse blocking single switch as a high frequency power supply circuit for DBD-FL using Xe gas are comparatively evaluated and discussed from a practical point of view.

Uyeki(1928) classified Pinus densiflora into six ecotypes(Northeastem type, Middle-southern flat type, middle-southern upland type, Wibong type, Ankang type, and Geumgang type) based on the pine tree type. The bark color of Geumgang type was ash-brown color on the lower parts of stem and yellowed color on the upper parts of stem. We investigated the physicochemical properties of soil forests to obtain basic data for preservation of exellent pine (Pinus densiflora for. erecta Uyeki). The results were as follows; The soil texture of the Pinus densiflora for. erecta Uyeki forests were showed nearly as sandy loam, that is, sand, silt and clay were consisted of 72%, 15% and 13%, respectively. Soil acidity(pH 4.6) was lower than Korea average forest soil acidity(pH 5.2). The average contents of available phosphate was 11.7ppm at Sokwang-ri, 26.8ppm at Mt. Eungbong, 24.2ppm at Mt. Kumma. It was the lowest at Uljin(4.6ppm). The contents of carbon was 6.2% at Mt. Chungok, 6.1% at Mt. Eungbong. This value was more than average of Korea forest soil.
