This study aimed to investigate the flood prevention effect expected from the afforestation of a large area metal roof of an industrial complex located in an area prone to floods in the rainwater outflow reduction aspect through computer simulation based on soil, which is a key element of the system. In order to conduct a more realistic simulation, the properties of the surveyed soil were generated through substantive analysis, soil texture analysis, and saxton method. A comparative performance evaluation was conducted by using soil depth and ponding depth, which are key elements of the system, as variables. The study result showed that during the heavy rainfall period, the bottom ash artificial soil had 61% rainwater outflow reduction effect, which was 11% higher than the SWMM standard sand.

Light environment in the school building is one of the most important elements of the plan in order to improve student's ability to learn and the healthy growth. Thus, the window plan of the school building is a great addition to improve environmental-friendly performance through the daylight control. Daylight is highly beneficial for improving the indoor environmental quality and reducing building energy consumption, daylighting applications are scarcely considered, especially during the school building design process, because of lack of previous studies on the light environment of student and complex simulation process. Therefore, daylighting process were performed using ECOTECT, which has various advantage such as easy user interface and simple simulation processes. ECOTECT simulation were performed using weather data. As a result, ECOTECT simulation are performed for daylight autonomy and useful daylight illuminance. Using this data, Window planing is to propose and effective method in the early stages of design.

Growth of cities and an increase in population result in the development-oriented policy, urban streams to lose their natural characteristics and functions by channelization, parking lot construction, and so forth. The streams fall into urban drains, which is the current status of urban streams. Recently, the interest in the stream environment and the ecosystem has been increased, and the efforts have been made to improve the traditional maintenance program for small streams. These efforts lead to the application of the natural recovery systems. This study applied the 240-meter model reach along the Oncheon stream, which locates in Dongrae-gu, Busan city. to analyze the natural recovery system. The efficiency of each system has been analyzed and the future improvements for the systems are presented. The results show that the stream maintenance program should consider the ecological environment. thereby minimizing the environmental effects. When the changes are inevitable, the maintenance program should adopt the methods. which closely simulate the original environmental elements. or are more favorable to the ecosystem.

The purpose of this study is to research the characteristics of literature related to environmentally friendly for a village-focused green index. In order to make an assessment, keywords relating to green architecture were selected: environmental friendliness, ecology, sustainable, Noksaek (Green in Korean), green, and environmentally friendly. In addition, three keywords defining the scope of space were also selected: building, village, and city. Quantitative changes and contents of articles containing the keywords were analyzed. The result is as follows. First, 'sustainable' and 'ecology' were the terms most frequently used as parts of subjects and titles, respectively. Second, the studies relating to green architecture focused on villages mostly examine the actual conditions of the villages; criteria for environmental friendliness, analyses and evaluation of the environmentally friendly features of the village; and ways to establish a green, ecological, and sustainable village. Finally, when it came to establishing a village-focused green index, the environment, resources, and energy are shown to be very important elements. In addition, the term 'ecology' in a green index is shown to be significant for the management of the natural environment.

This study was aimed at developing eco-STEAM educational programs based on smart learning, implementing the programs to verify their educational effectiveness, and exploring the possibilities for eco-education. The subjects of Science, Mathematics, Practical Arts, Arts, and Physical Education were analyzed to extract STEAM elements for the 5th and 6th grades at elementary school, and then 16 lessen plans were developed under 8 thematic strands. The programs were applied to classes of 5th and 6th graders, and then tested to see the effectiveness in terms of emotional experience, convergence, creative design and satisfaction. The average scores for post-test were statistically higher than those of pre-test(p<.001), showing positive effectiveness of the eco-STEAM programs developed. This study put out the following conclusions. First, the students got emotional experiences through inquiry and observation. Second, the programs helped students to learn about the environment in their contexts and provided a base for interdisciplinary approach. Third, the students in this study could have opportunities for improving their problem-solving abilities by using the creative design. Forth, the students' interests in the ecological topics were increased throughout regular curricula.

Pollen analysis of moor peat of Daeam Mountain revealed vegetational history around Daeam Mountain. The pollen stratigraphy might be zoned into three, Zone I, Zone II and Zone III for the past 2, 200 years. The time required for amount of the accumulated peat in the moor was estimated in terms of the balance of the accumulation and decay of organic carbon of the deposit peat. Zone I(770~2, 200 yr BP) had Pinus and Quercus as main elements. Gramineae decreased while Typhaceae, Cyperaceae and spores such as Polypodiaceae increased. Zone II(300~770 yr BP) showed warming trend which is suggested by high pollen concentrations of Quercus, Juglans, Carpinus, Ulmus and by a more diverse flora of deciduous borad-leaved trees than Zone I. Pinus decreased in this zone. It suggests that the overall environment became milder than Zones I and III. Zone III(earlier than 300 yt BP) was predominantly Quercu and Pinus with amount of nonarboreal species such as Artemisia, Gramineae and Chenopodiaceae, that was grown under dry conditions. It suggests that overall environment vecome humid by comparison with the present time and it is surmised the course of boggy ground formation by a retrogressive succession.

As environmental problems and water-shortage phenomenon become a global issue, many states look for the effective method to use water resources. So, decentralized rainwater management is recognized as a new water management system that rainwater can be infiltrated and used on-site. But it is little difficult to build a park, lake, and forest for evaporating rainwater in city because the land price of city is very high. In order to build an excellent infiltration system for a dwelling and a park in Korea, KICT has developed Linear infiltration system. This infiltration system is consist of first flush treatment, storage and infiltration, overflow control system. These elements are connected closely and working as a combined system. A storm sewer can be changed by the linear infiltration system. This study is to show real application idea about Linear infiltration system with improving some detail in apartments. For this purpose, we devide application idea into the artificial ground and the natural ground and each ground type, suggest a method to cooperate with the other landscape and linear infiltration system. Through this study, we came to recognize a recognition difference of an expert and a commoner about decentralized rainwater management.

In the United States, forest administration is a constantly changing complex of policies, programs, and management regulations. Forest administration is the product of a brief but tumultuous history during which much of the forests which once covered half the land were coutover for farms, industry, and cities. In the last 15 years, forest administration has been increasingly dominated by concerns for maintaining an ecological balance. Current forest administration is deeply rooted in the American traditions of decentralized federalism and free enterprise, yet combines state socialism and private capitalism. The major elements of U.S. forest administration consist of : 1) programs and policies on taxation, professional education and research, and "cooperative forestry", 2) state controls on forest practices for privately owned lands, and of federal policies and regulations for the management of federal lands. The federal Forest Service has played a lead role in developing and implementing national forest policies and programs. Since the end of World War II, the national forests managed by the Forest Service for multiple use have provided and ever growing fraction of domestic timber needs. In the coming decades, cultural and social trends may force a change in management policy on federal land, reducing the importance of timber harvesting in relation to amenity values.

This study is to analyze establishment status and planning characteristics of the landscape master plan of 22 cities and counties in Jeollanam-do, Korea. The landscape master plans have been established in 19 cities and counties and among them they were established in 11 cities and counties before 2010. They tend to be made in city governments earlier than county governments. Community visions are implied with four meanings, 'landscape ecological', 'administrative economic', 'historical cultural', 'abstraction sensitive' in expression. For setting zones, axises, and bases of landscapes, characteristics of each landscape zone are emphasized with unification and connectivity of axises and bases of landscapes as one unit to local governments. Proposal of design principle or guideline of landscape by elements tend to be higher than landscape types. Locational characteristics of local governments have influenced to landscape types and characteristics of natural environments have been strongly reflected in landscape plan in particular.
