Environmental sculpture is not just a decoration for architecture. It is a work of art with public interest and one of the best ways to improve street landscape design. Place of installation is very important for environmental sculpture, because it has close relationship with its surroundings and regional context. Field survey was performed on Teheran-Street, between Samsung station and Yeoksam station, central business district of Kang-Nam where lots of major buildings are located. All the 28 environmental sculptures facing Teheran-Street were examined. Relationship between environmental sculpture and street landscape design was investigated by three different points of view, relationship with architecture, intimacy with pedestrian, and space defined by the environmental sculpture. Environmental sculpture needs its own space and appropriate place to have beneficial influence on the sense of place. Environmental sculpture is important factor to control the quality of street landscape design. We should have macroscopic approach to determine place of installation, method and material of Environmental sculpture.

Recently, due to worldwide industralization and urbanization, natural environment has been severly damaged and global warning is worsening. Heat wave, torrential rainfall, typhoon and other natural disasters continuously occur due to global warming. Policies such as carbon emission regulation are taken into effect to solve such problems. Such global trend has affected interest to natural ecosystem and developed as a concept of ecosystem-services. This study particularly focused on ground water storage capacity among various ecosystem-services such as climate control and soil formation. It is because Korea suffers from drought and flood every year. Therefore, this study aims to understand objective numerical value of ecosystem-services value regarding ground water storage capacity of biotop classes based on relationship among precipitation, amount of evapotranspiration, and runoff of 7 regions of Chilgok-gun, Gyeongsangbuk-do and to convert the value into economic value. The study calculated ground water storage capacity based on relationship among precipitation, amount of evapotranspiration, and run off. Calculated amount of each capacity was 29.26 million ton($30.2mm/m^2$), 430.46 million ton($140.4mm/m^2$), 11.30 million ton($150.1.0mm/m^2$), 33 milion ton($3.0mm/m^2$). Economical value of ecosystem-service by each biotop classes appeared 4,128,800 thousand KRW ($21.32KRW/m^2$) for agricultural biotop, and 60,403,600 thousand KRW ($98.52KRW/m^2$) for forest biotop, 1,572,800 thousand KRW ($104.4KRW/m^2$) for grassland biotop, and 47,600 thousand KRW ($2.18KRW/m^2$) for bare ground biotop. The result of this study like above, it will be used as important evidentiary material to preserve natural resource effectively from various development business and policies that damages natural eco-system. Also, it is judged that ecosystem-service value by each land coverage will be used as important material for preparing legalistic institution such as establishing natural environment preservation plan, budget for alternative forest resource creation cost.

Overall 25~30 new golf courses are opening in Korea these days, and total annual rounds have been also increasing by 10~15% every year. The Korean golf industry is being recognized as the largest growing golf industry in the world. However, it is easily defined that there are many problems of golf course development and construction methods such as construction fees. The average construction cost for golf course development and golf course maintenance fees in Korea are much more than the cost in the USA and other countries. It may be due to the fact that USA golf course development is managed by a highly developed construction method and well trained specialists. This study will be concentrated on one of the major differences, which is about cart path material; this causes a big difference of construction and maintenance fees. In order to overcome this study, concrete and asphalt will be specified as the main cart path material. Also, some case studies and construction regulations of golf course development in the USA will be introduced for a better understanding of this study.

The study conducted an experiment in which residual aggregate and polypropylene fibers are mixed in concrete, and an experiment in which granite and polypropylene fibers are mixed. Two types of experiments, in particular, changed the amount of polypropylene fibers, and examined the mechanical properties of slump, compressive strength, tensile strength and the like. To establish a light and easy-to-use material for landscape construction and packaging material development by comparing two kinds of experimental results, comparing and analyzing residual aggregate as experimental materials and materials using granite soil to prevent partial destruction due to cracks in drying shrinkage. The more the amount of the PP fibers increases in concrete, the more the volume of the PP fibers increases, the less the slump is determined. As a result of the compressive strength, the cast-down earth concrete is measured to be about 59% to 71% of the concrete strength. As the amount of PP fibers mixed in increased, the compression strength showed a relative decrease. As a result of tensile strength, it is found that the granite concrete is about 68-67% of concrete tensile strength. It was found that the compression strength decreased as the amount of PP fibers mixed in concrete or fire-gant concrete was increased. Then, when polypropylene fibers are mixed in the concrete and the concrete, it is found that tensile strength is increased. By analyzing these results, a fixed amount of PP fiber is mixed in the concrete mixed with the granite soil and utilized for various structures in the field of landscape construction or materials related to packaging, the prevention and improvement effect of the structure is determined.

This study aims to understand the tendencies and characteristics when constructing landscape architectural archives in the United States, and to find implications for creating Korean landscape architectural archives. Focusing on seven American landscape architectural archives operated by public institutes, universities, and research institutes, this study examines the background, mission, scope, subject, acquisition, arrangement, and application of the programs in the archives. The results show that the characteristics of the American landscape architectural archives are as follows: first, the recognition of the value and importance of the landscape plays a major role in the establishment of archives; second, the purpose of the archives is to educate and encourage people to find diversity or significance of landscapes; third, the subject and scope of the archives vary according to the purpose of each operating institution; fourth, the main acquisitional method is to receive a donation and to purchase materials or documents; fifth, the classification systems of each archive differs depending on the subject and scope; and sixth, the archives were built on the basis of participation and collaboration with various experts and organizations with stable and sustainable financial resources. These characteristics offer three implications for constructing landscape architectural archives in Korea. First, a long-term vision for landscape architectural archives and the establishment of differentiated themes are required. Second, appropriate methods of material collection and systems of classification, recording, and digitization are necessary and therefore research and pilot archives are required. Third, it is necessary to secure the sustainability of archives by developing ways to utilize the archives in connection with academic and educational programs, thereby securing financial resources and allowing for the establishment of appropriate policies. As basic research, this study is significant as it provides a basis for further research concerning the development of landscape architectural archives in Korea.

An abundance of information is available regarding soil horizons and their characteristics. Several methods can be used to gather and analyze this information. Through the use of qualitative analysis in the field, and laboratory and statistical analysis, a soil can be compared and analyzed with a great deal of scrutiny. Four soil pits were excavated in Citrus County Florida and samples were collected from each master horizon. Through the use of qualitative and quantitative analysis these samples were compared and analyzed in order to identify unique, as well as homogeneous features. It was determined that the soil profile designated Old Pit was different than other profiles because of landscape position and variations in parent material. Landscape position (ie. slope position) also influenced the genesis and evolution of the soils in the other three profiles(Profile 1, 2 and 3).
