The relative difference between Korean rural region and urban region has increased by the rapid urbanization and industrialization since 1960. Therefore it will be important to raise the income of the people living in rural region. So the Korean government established the collective side job area and rural industrial area for the increasing of the non-agricultural income. For this, the touristic resources development is also the another important means of the rural region development. So the purpose of this thesis exists in the presentation of the direction of the touristic resources development in rural region. For this purpose, three representative regions among the Korean rural regions were selected and the case study was accomplished. In this way the rough direction of the touristic resources development in rural region has presented The direction of the development and the conclusion were as follows : 1)Planners must establish the planning with the vision and demand of future than percent condition. 2)Because the urbanization is continued incessantly, the rural region is developed to be the space of resort. 3)The touristic resources development in rural region is contributed to the regional development through the raising interaction of the touristic resources. 4)The rural region is developed to be the space of the Korean rural tradition 5)The grassland os constructed in the mountenous land and the landscape of the Korean national land is changed to be the picturesque landscape. 6)The construction of the traditional artistic products is accomplished to increase the income of the people in rural region.

A numerical assessment using mesoscale-CFD (computational fluid dynamics) coupled A2C (atmosphere to CFD) model was carried out to analyze the variation of microscopic air flow pattern due to the construction of the Chilgok barrage in the Nakdong River. Scenarios with air flow patterns were classified into pre- and post-construction. The increased width of the river due to the construction of the Chilgok barrage induced obvious changes in moisture and the thermal environment around the river. However, air temperature variation was restricted within an area along the windward side in the numerical assessment. The impact of barrage construction on air temperature tends to be stronger during the nighttime than the daytime. It also stronger during the winter than the summer. In the simulation, the convergence of mesoscale wind is more pronounced after barrage construction than before. This is caused by the change of heat flux pattern induced by the widening of the river. Although this work is a case study with restricted atmospheric stability conditions that has several limitations in the numerical simulations, the impacts of the land-use changes brought about by the construction of the barrage in the river acceptable.

건물운용단계의 에너지사용량은 우리나라 전체에너지 사용량의 약 25%이다. 지금까지 건물의 에너지사용량을 줄이기 위해서는 주로 설계단계에서 단열을 강화하고 고효율 기기를 사용해왔다. 이러한 노력들은 에너지절약 측면에서 그 한계가 있으며, 사용단계에서의 에너지절약생활이 큰 비중을 차지함에 따라 입주자들의 자발적인 참여로 인한 에너지절약 방법이 보다 효과적이라 할 수 있다. 이를 위해 본 연구에서는 에너지사용자에게 보다 적극적으로 에너지절약 프로그램에 동참시키기 위해 본인들이 사용한 에너지실적 정보를 웹상에서 서로 공유할 수 있는 프로그램을 개발하였다. 또한 프로그램의 필요성 및 사용의지를 조사하고 시범 적용하여 유효데이터의 수집가능성과 프로그램의 사용 용이성에 대하여 평가하였다.

In order to develope a road landscape that is in harmony with landscaping purpose, degree of sight occupation by slopes at road sides was measured and physical elements composing the slope scenery were visually evaluated and the results are as follows : In analysis of sight occupation ratio by perspective method, gradient of the slopes influenced more on the sight occupation than height did and the driving lane occupied 2 to 3% more proportion of sight than the passing lane. When there is slope at one side of the road, difference in sight occupation between the lanes was increasing with deceased height and with increased gradient of the slopes. In visual analysis of the slope scenery, negative image was increasing with narrow road, increased height and gradient of the slopes. In visual analysis of the slope scenery, negative image was increasing with narrow road, increased height and gradient of the slopes. Particularly, the effect of gradient was critical on scenery. The effect of the slopes was negative at 60$^{\circ}$ or more but positive at 45$^{\circ}$or less gradient. This phenomenon was more conspicuous with wide 4 lane roads than wide 2 lane roads. Although direct comparison is difficult due to a great difference between Korea and U.S.A. in climate, land condition, road dimension, and public process of purchasing land, etc, it is desirable to treat road sides so that the scenery is in harmony with landscape around as well as emphasizing the regional characteristics, also giving friendly and comfortable image to drivers and nearby residents in addition to safety as can be seen in U.S.A.

In this paper, a multi-agent control system for DC-coupled photovoltaic (PV), fuel cell (FC), ultracapacitor(UC) and battery hybrid power system is studied for commercial buildings & apartment buildings microgrid. In this proposed system, the PV system provides electric energy to the electrolyzer to produce hydrogen for future use and transfer to the load side, if possible. Whenever the PV system cannot completely meet load demands, the FC system provides power to meet the remaining load. A multi-agent system based-power management and control algorithm is proposed for the hybrid power system by taking into account the characteristics of each power source. The main works of this paper are hybridization of alternate energy sources with FC systems using long and short storage strategies to build the multi-agent control system with pragmatic design, and a dynamic model proposed for a PV/FC/UC/battery bank hybrid power generation system. A dynamic simulation model for the hybrid power system has been developed using Matlab/Simulink, SimPowerSystems and Stateflow. Simulation results are also presented to demonstrate the effectiveness of the proposed multi-agent control and management system for building microgrid.

댐 저수지의 높은 수위와 댐 외부 지역의 지하수위간의 수두 차이는 지질 방벽을 통한 물의 흐름을 발생시킨다. 이로 인하여 발생한 유역 외 지역의 얕은 지하수위는 토양 습윤화를 초래하여 토지이용에 제약을 가져온다. 본 연구에서는 습윤화가 진행된 소유역내에 지하 1~1.5 m 심도에서 유공관 등의 배수시설을 설치한 후 그 효과를 분석하였다. 배수시설 설치 이전에 비하여 지하수 관측정에서의 수위는 1 m 이상 하강한 것으로 나타났으며, 저수지와 인접한 골짜기 상류(W1 지점)의 경우에는 2m 이상 하강하여 지하수의 빠른 배출에 의한 효과가 발생하였다. 또한, 지역 내 토양수분함량 및 그 표준편차도 감소하여 배수시설에 의한 지하수위 하강이 토양 습윤화를 억제한 것으로 분석되었다. 댐의 설계 시에는 지형지리적 특성을 고려하여 수두 차이에 의한 외부 지역으로의 누수 현상 예측 및 관련 대책을 수립해 나가야 한다.

간척지 갯벌지반 식재 수목에 생장 저해하는 토양염분의 이동을 차단하는 염분차단재, 염분차단 위치 및 염분차단 두께에 따른 토양염분의 경시적 변화에 대하여 조사 분석하였다. 7가지의 토양염분이동 차단재료, 3가지의 차단두께 유형 그리고 토양염분이동차단 3가지 유형별로 염분의 변화가 다르게 나타났다. 갯벌지반은 초기에 토양염분이 높았으나, 점차 낮아졌다. 식생토인 객토는 초기에 토양염분이 낮았지만, 토양염분이동 무차단구에서는 점차적으로 토양염분이 높아졌고, 토양염분이동 차단구에서 전면차단구는 토양염분의 변화가 크지 않지만, 토양염분이동 벽면차단이나 밑바닥 차단만한 곳에서는 토양염분이 높아졌다. 토양염분은 강우시에는 토양염분이 낮아지나, 가뭄기에나 겨울철에는 토양염분이 높아지는 현상이 있었다. 토양염분이동 차단재료별 토양염분이동 차단능은 쇄석, 준설토, 목질칩이 다른 재료들 보다 우수하였다. 토양염분이동 차단벽은 최소한 20cm 이상 되어야 효과가 있는 것으로 나타났다.

Using three-dimensional non-hydrostatical numerical model with one way double nesting technique, atmo­spheric circulation in the mountainous coastal region in summer was investigated from August 13 through 15, 1995. During the day, synoptic westerly wind blows over Mt. Mishrung in the west of a coastal city, Sokcho toward the East Sea, while simultaneously, easterly upslope wind combined with both valley wind from plain (coast) toward mountain and sea-breeze from sea toward inland coast blows toward the top of the mountain. Two different directional wind systems confront each other in the mid of eastern slope of the mountain and the upslope wind goes up to the height over 2 km, becoming an easterly return flow in the upper level over the sea and making sea-breeze front with two kinds of sea-breeze circulations of a small one in the coast and a large one in the open sea. Convective boundary layer is developed with a thickness of about 1km over the ground in the upwind side of the mountain in the west and a thickness of thermal internal boundary layer from the coast along the eastern slope of the mountain is only confined to less than 200 m. On the other hand, after sunset, no prohibition of upslope wind generated during the day and downward wind combined with mountain wind from mountain towardplain and land-breeze from land toward under nocturnal radiative cooling of the ground surfaces should intensify westerly downslope wind, resulting in the formation of wind storm. As the wind storm moving down along the eastern slop causes the development of internal gravity waves with hydraulic jump motion in the coast, bounding up toward the upper level of the coastal sea, atmospheric circulation with both onshore and offshore winds like sea-breeze circulation forms in the coastal sea within 70 km until midnight and after that, westerly wind prevails in the coast and open seas.
