The present conditions of Sanyangri village at Samcheok are stagnated and spiritless because there is only old men without young men. The purpose of this study is to make the basic plans of this rural and mountainous village to learn by personal experience. Therefore this study has been focused on its programs, land uses, roads and facilities how to activate it. The plan orientation of it is to make and become active by tourists to visit this village to experience the rural and mountainous living culture. So the general plan is divided into two zone which are the rural experience zone and the mountainous experience zone. Also the plan is to be considered to increase its amenities through the connection of surrounding villages and their resources. And it is necessary for the conversion as a tour place of sojourn and experience by supplying with various shows through connections with surrounding tour resources worthy of providing the various excitement through the visiting.

Odor control for livestock and compost facilities has focused on manure handling and treatment during storage and land application, however, large amount of malodorous air is emitted and it is one of main sources of malodour in livestock farming. Biological treatment or biodegradation involves converting an organic contaminant to carbon dioxide and water using natural bacteria. Biofiltration is an effective air pollution control technology that uses microorganisms to breakdown gaseous contaminants and produce innocuous end products. Investment and operating costs on the biofiltration are lower than for thermal and chemical oxidation processes. This paper is intended to provide an overview of basic design and operating criteria for biofilters to control odors from livestock and compost facilities.

As our global population grows each day, it is apparent that we must find new ways to provide space for habitation and the services necessary to support large urban areas. It is no longer advisable nor acceptable to continue to expand our cities on the surface, encroaching on valuable agricultural land and open space. We must also find ways to be more energy efficient in every aspect of our societies. Effective use of underground space can provide the space necessary to accommodate larger populations and the services necessary for their support in existing urban areas we can also find new ways to utilize underground facilities to improve urban efficiency and function. Underground technology has improved dramatically in the last two decades and continues to evolve to meet a great variety of applications. The confluence of available technology, economic feasibility, and greater acceptance of underground solutions with recognition of the need to change the ways we build and use out urban areas and their surrounding environment indicates that we are witnessing only the beginning of appropriate and innovative use of underground space future generations will indeed 'Think deep'.

The domestic Remote Sensing field uses mainly Landsat TM image that is used to the monitoring of the wide area. In this study, it is analyzed the land cover change of rural and urban area by time series using satellite images and is proposed the vision for a urban balanced development. It execute an analysis for urban change which is a fundamental data of city planning through the integration of the spatial analysis technique of GIS and Remote Sensing using satellite data

This Paper presents a novel piston friction force measurement system that has characteristics of relieving the Pressure force acting on the upper surface of the liner; the system uses general rubber O-rings for combustion chamber sealing, and does not need special changes to the piston top land. The lower supporter of the floating liner increases stiffness in liner axial direction, and results in the increase of natural frequency. The upper supporter has multi-layer structure designed fer low axial stiffness and high radial stiffness. With the use of the present system, the effects of variation in clearance and piston ring tension were studied.

An efficient method for the unsupervised classification of high resolution imagery is suggested in this paper. It employs pixel-linking and merging based on the adjacency graph. The proposed algorithm uses the neighbor lines of 8 directions to include information in spatial proximity. Two approaches are suggested to employ neighbor lines in the linking. One is to compute the dissimilarity measure for the pixel-linking using information from the best lines with the smallest non. The other is to select the best directions for the dissimilarity measure by comparing the non-homogeneity of each line in the same direction of two adjacent pixels. The resultant partition of pixel-linking is segmented and classified by the merging based on the regional and spectral adjacency graphs. This study performed extensive experiments using simulation data and a real high resolution data of IKONOS. The experimental results show that the new approach proposed in this study is quite effective to provide segments of high quality for object-based analysis and proper land-cover map for high resolution imagery of urban area.

Phytoremediation which uses plants to enhance the bioremediation through stimulation of microbial activity and root uptake, has been a topic of increasing interest. Mathematical model were developed that can be applied to various bioremediation methods in the unsaturated zone, especially phytoremediation, for simulating the fate and transport of contaminants under field conditions. A 2-year field study was conducted using 72 (1.5m long and 0.1 m diameter) column lysimeters with four treatments: Johnsongrass; wild rye grass; a rotation of Johnsongrass and wild rye grass; and unplanted fallow conditions. The developed model represented the fate and transport of contaminant both in vegetated and unplanted soils satisfactorily for field applications. Parameters related to the contaminant concentration in the water phase were the main parameters determining the contaminant fate in the vadose zone and indicated that the bioavailability can be the most important factor in the success of phytoremediation as well as bioremediation applications.

본 연구에서는 SWAT 모형의 경안천 유역에 대한 적용을 퐁하여 유출 및 유사 모의와 관련된 주요 매개변수들을 보정하고, 보정된 모형 매개변수를 적용하여 검증을 수행함으로써 모형을 이용한 국내 유역에서의 유역 유사량 해석 가능성을 평가하였다. 특히, 유사 측면에서는 충분하지 못한 자료로 인하여 모형 보정만을 수행하였고, 비록 정량적인 모의에 있어서는 정확성이 다소 떨어지지만, 정성적인 경향은 잘 모의할 수 있었다. 또한, 유사 거동의 공간적인 분포 특성을 파악하기 위해 소유역 크기 및 토지이용에 따른 비유사량을 산정하여 검토함으로써, 유역내 소유역 면적별 비유사량의 일정한 관계를 파악할 수 있었고, 토지이용별 침식 영향을 판단할 수 있는 개략적인 평가를 할 수 있었다.

This second stage study on the Wild and Scenic Rivers System is a proposal for system disignation. Study area is the part of the Han River flowing through the Seoul Metropolitan Region. Consequently, developpment pressure and demand for recreational land uses along the river are very high, and that is why the Wild and Scenic rivers System is urgently needed for the Han River among other major rivers of the nation. Resource inventory and assessment followed the process developed in the first stage study. Figure-4 shows the proposed Wild and Scenic Rivers System designation, Also proposed are manage-ment guidelines and legal, organizational arrangement.

From the 1978 Seasat synthetic aperture radar(SAR) to present systems, spaceborne SAR has demonstrated the capability to image the Earth's ocean and land features over broad areas, day and night, and under most weather conditions. The application of SAR for surveillance of commercial fishing grounds can did in the detection of illegal fishing activities and provides more efficient use cf limited aircraft or patron craft resources. In the area of vessel traffic monitoring for commercial vessels, Vessel Traffic Service (VTS) which uses the ground-based radar system has some difficulties in detecting moving ships due to the limited detection range cf about 10 miles. This paper introduces the field testing results of ship detection by RADARSAT SAR imagery, and proposes a new approach for a Vessel Monitoring System(VMS), including VTS, and SAR combination service.
