This thesis attempted to generate ideal tea culture space that connects environment and culture. Therefore, this examines: First, history of tea and the characteristics of tea culture space from Gochosun to modern times was reviewed Second, psychological factors (spirit of tea) of Korea tea culture space were reviewed. Third, the connection between the concept of tea culture space and Human Ecosystem Model by was analyzed. Also, this thesis examined how the culture of ecosystem and why tea culture space is needed. because tea includes varieties of ingredients for protecting environmental pollution. Finally, tea culture spaces were reviewed each region during Chosun dynasty, and tea culture space of recent tea users. In order to study tea culture space, complex residential area and single residential areas were compared. The useful of tea culture space as a ecological space was also examined. To achieve the purpose of this study, related literatures were reviewed, and investigations of museums and a survey on modern living space were also conducted. The results show that the space of our tea culture were affected by nature worshipping of Gochosun, Buddhism of Koryo, and Confusianism of Chosun with 'Pungryu', the idea that enjoys nature, thereby applying environment-friendly ecological beauty to their living space and life. The cultyral space in Korea is composed of natural environment such as mountain, sea, rock, or trees and artificial environment such as pond or pavilion. In the future, oriental culture with metaphysical value will lead the world culture, and especially, tea culture would play an important role regardless of nationality, race, religion, and ideology. Therefore, establishing a tea culture space in a living space would be the fundamental methods that would be able to settle down such tea life into our daily life. Our attempts to create ecological tea culture space as a integrated cultural space of natural, artificial, and human behavioral environment will contribute to enhance our quality of life.

The aim of this study is to investigate distribution characteristics of incised meander cutoff in Gyeonggi and Gangwon Provinces of Central Korea. The density of meander cutoff is highest in the mountain rivers including Naerin and Dongdae flowing on Jeongseon-gun and Inje-gun of Gangwon Province. Most of meander cutoff process has been occurred repeatedly during the Quaternary period, especially concentrated in the period of climatic change between glacial and interglacial stages. In the aspect of the lithology, the density of cutoff is highest in sedimentary rock, but lowest in igneous rock. As for geological structure, its frequency is high at $11{\sim}20km$ westerly away from the Taebaek Mountains, at subsequent channel, lower part of resequent channel, and channels crossing the fault line. The relation between distance from the Taebaek Mountains and altitude is very obvious at the western side of the Taebaek Mountains. The values of altitude, height from riverbed, and stream order are highest at sedimentary rock and lowest at volcanic rock.

Forest resources are the most important element that can affect the nature environment directly in modern society. Due to the fast industrialization of our country and marginal states like China, many people suffer torments from severe environmental pollution like yellow and fine dusts everyday recently. So the interests concerned about the significance of nature and environment become major issue nowadays. Precious forest resources, however, are not properly managed and destroyed vainly due to frequent mountain fires, damages by floods, and unplanned land development in real world. Therefore, efficient forest management is required to solve these problems effectively. In this research, we design and implement the forest information database that can predict the growth of forest resources and enables us to manage forest resources efficiently, make decision for logging, build the waterway to prevent flooding, and construct a future tree-planting project easily using forest aerial photograph taken by a drone in order to deploy and manage the forest resources scientifically and systematically.

The present study was accomplished from October, 1992 to June, 1993 in order to examine the seasonal community structure of aquatic insects and the biological estimation of water quality by the aquatic insects of the Jungneung and Gokneung streams in the Mt. Bukhan. The obtained results are as follows: 1. The total taxa of aquatic insects appeared as 77 species, 45 genera, 28 families in 7 orders. 2. Seasonal occurrence species numbers showed the highest in the autumn of the Jungneung stream (19 species) and in the spring of the Gokneung stream (41 species). Seasonal occurrence individual numbers showed the highest in the summer of the Jungneung and Gokneung streams (5,901, 3,180 individuals) and the lowest in the autumn of Jungneung stream (612 individuals) and in the winter of the Gokneung stream (1,764 individuals). 3. Annual dominance indices showed 0.52 (stJ1)~1.00 (st.J3) range in the Jungneung stream, and 0.47 (st. G1)~0.76 (G2) range in the Gokneung stream. 4. Seasonal species diversity indices showed 0.00 (st J3, whole seasons)~3.12 (st.J1, Spring) range in the Jungneung stream and 0.69 (st. G2, summer) ~3.10 (st. G4, spring) in the Gokneung stream. 5. Biological saprobic system based on species diversity indices of aquatic insects appeared as oligosaprobic area: site J3, $\alpha$-mesosaprobic area: site J2, G2, G3 and $\beta$-mesosaprobic area: site J1, G1, G4.

This study monitored forest plant species vulnerable to climate change in Jiri Mountain, one of Korea's representative alpine regions, in order to securely preserve plant genetic resources susceptible to climate change and to utilize the results as basic data for bioclimatology prediction and management on a long-term basis. A majority of indicator plants tended to blossom one week to one month later in 2010 than in 2009. As with the blooming dates, the falling dates of blossoms became later in most species, with the exception for Weigela florida and Oplopanax elatus. Leaf bursting as well fell on later dates in a majority of species excluding Carpinus laxiflora and Cupressus sempervirens, displaying the most obvious differences among the data of analysis of the 2009-2010 physiological cycle changes. It is believed that was due to the fact that temperatures in February, March and April, which affect plants' blossoming and leaf bursting, were lower in 2010 than in 2009 and that cold temperatures in the winter lasted for a longer period in 2010 than in 2009. The dates of leaves being changed to red were similar in 2009 and 2010 by being or later or earlier by several weeks in 2010 than in 2009 without any regularity. Most species' leaves began to fall at similar dates in 2009 and 2010 or at later dates by one to two weeks in 2010 than in 2009. The temperature differences in late 2009 and late 2010 were not so large, resulting in similar dates of falling leaves, and gaps in several indicator plants' physiological cycles without any regularity can be attributed to each individual plant's physiological and environmental characteristics.

HPAI (High pathogenic avian influenza) which is a disease legally designated as an epidemic generally shows rapid spread of disease resulting in high mortality rate as well as severe economic damages. Because Korea is contiguous with China and southeast Asia where HPAI have occurred frequently, there is a high risk for HPAI outbreak. A prompt treatment against epidemics is most important for prevention of disease spread. The spread of HPAI should be considered by both direct and indirect contact as well as various spread factors including airborne spread. There are high risk of rapid propagation of HPAI flowing through the air because of collective farms mostly in Korea. Field experiments for the mechanism of disease spread have limitations such as unstable weather condition and difficulties in maintaining experimental conditions. In this study, therefore, computational fluid dynamics which has been actively used for mass transfer modeling were adapted. Korea has complex terrains and many livestock farms are located in the mountain regions. GIS numerical map was used to estimate spreads of virus attached aerosol by means of designing three dimensional complicated geometry including farm location, road network, related facilities. This can be used as back data in order to take preventive measures against HPAI occurrence and spread.

The problem of outdated and surplus facility-items in existing Rural Living Environment Renewal Program(RLERP) makes this study focus on restricting the range of facility sorts for the purpose of coㅁins with the changing rural living environment. In the four aspects of plan establishment, project implementation, comprehensiveness and linkage between programs, this study made an analysis of the existing RLERP that has 4-stage hierarchy, namely, Gun(county), Myun(primary administrative district), village and project site level Firstly, Myun and upper level policy programs fulfill the comprehensiveness and planning aspects, but have defects in the implementation and linkage aspects. Secondly, the village level programs satisfies more or less the four condition, but give rise to the problems of equity between the project target village and the non-target, and of generalization of the planning method applying to a specific village. At last, project level programs, controlled by several ministries, have defects in comprehensiveness and linkage aspects, exposing the sectoralism of central government. Above all, the existing RLERP has so many facility items, which have led to inefficient investment till now. Therefore, it's necessary that the environmental facilities should be selected(simultaneously reduced ), referring to following 5 criteria. (1) Exception of facilities relating to agricultural production. (2) Confined to public facilities to be constructed by government support. (3) Common-use facilities located in small town and below level area. (4) Consideration of not only the present need but also the future need of rural residents. (5) Reflection of a regional difference of mountain, plane and suburban area. Just 13 kinds of living environmental facilities are finally selected as the result of the selecting work, which can be an new alternative for RLERP. Concludingly, the selected facility items should be integrated into a designated project site by the prepared plan in order to enhance the efficiency of RLERP, investment and also to satisfy the four analytic aspects mentioned above.

A numerical model of surface runoff and river flow has been applied to small- and large-size catchment areas in order to investigate the physical characteristics of river flow during flood period. Several refinements are made on the existing model SIRG-RS for the ways of rainfall input through surface runoff, river junction treatment and the computation of river flow on steep slope. For the computation of frictional forces, employed is the power law of friction factor which is a function of Reynolds number and relative roughness height. The empirical equation of friction factor is developed using recent field data as well as laboratory data. The refined model has been applied to small-size catchment area as well as large-size catchment area, and the computation results are found in good agreement with the observations in both cases.

The goals of this study were to develop indicators that are able to evaluate the accomplishment of the projects for rural traditional theme villages and make developmental suggestions for a balanced development of rural communities using the indicators. Human, economic, and social factors were selected as the evaluation indicators. The importance of the performance indictors was analyzed by AHP (Analytic Hierarchy Process). The importance of the performance indictors was in the order of satisfaction of inhabitants (150), participation of inhabitants (145), economic effectiveness (123), lodging facilities (101), leader training (96), project cognizanc e(90), etc. As these evaluation methods were applied to the six villages, haebari village came first followed by darangyi village, namsayedam village, mulrebangatteok village and Yedong Mountain fishing village. This study proposed a way of improvement for the balanced development of the rural communities in terms of human, economic and social aspects.
