  • 태양광발전은 태양의 복사에너지를 직접 전기에너지로 변환하는 시스템으로 가동부분이나 열기관이 없어 수명이 길고 운전과 유지보수가 용이하며 모듈로 구성되기 때문에 수요나 지형에 맞게 설계할 수 있다. 이러한 특성으로 인해 태양광 발전은 차세대 성장 에너지원으로 각광 받고 있으며, 최근 문제되고 있는 지구환경문제 해결에도 부합할 수 있는 잠재력을 갖고 있다. 또한 계통 연계형 태양광 발전시스템의 확대 보급시 태양광 발전시스템의 출력특성에 의한 기존 전력계통의 피크전력을 감소시키는 효과도 기대할 수 있다. 국내 태양광발전은 정부 지원정책에 힘입어 지속적으로 보급이 확대되고 있으며, 2009년도 기준으로 약 400 MWp 이상의 설비가 전력시장에 진입하여 상업 운전중에 있다. 태양광발전시스템은 육상에 설치하는 것이 주류를 이루고 있었으나 태양광 입지조건에 적합한 부지를 확보하는 것이 쉽지않기 때문에 최근에는 건물옥상이나 벽에 설치하는 사례가 증가되고 있다. 본 논문에서는 한전전력연구원(대전시 유성구 문지동)의 건물옥상에 설치되어 운전하고 있는 9.52kW급 BIPV 형식의 태양광발전시스템을 대상으로 2010년도 1년간의 운전특성에 대하여 분석 평가하고 이를 통해 BIPV시스템의 운전에 대한 기초자료를 제시하고자 한다.

  • Global consumption of fossil fuels continues to increase. As developing countries use fossil fuel as much as the existing fossil fuel using countries, the total amount of fossil fuel consumed has risen. The finite fossil energy depletion insecurity have become serious. In addition, fossil energy is caused by environmental pollution, economic and social problems remain in assignments that need to be addressed. Although solar power is clean and has many benefits, there are several problems in the process of installing a solar power plant. To solve these problems, floating photovoltaic plants has emerged as an alternative. This floating photovoltaic plants location analysis has not been made yet. In this study, the conditions of the floating photovoltaic plants location is analyzed with the Analytic Hierarchy Process using the terrain and climate factors. The score is assigned to the attribute information of each factor by the classification table. After multiplied by the weight the result is analyzed by visualization of the score. As the result, the score of the northen part of Gyeongsangbuk-do province is higher than the southern part of Gyeongsangbuk-do province. Especially Andongho lake in Andong City and the reservoir in Yeongyang-Gun are extracted as the optimal location. The score of the river boundary is low not the center of the river stream. It is expected that this study would be a more accurate floating solar power plant location analysis.

  • A study was initiated to investigate whether the groundwaters being discharged into the sea could be used as a possible water resources. This paper presents a preliminary information about the groundwaters being discharged along the shoreline of East Sea. Major discharge sites were selected primarily on the basis of the informaion on surface temperatures of the sea. Hydrogeologic and geographic conditions were also considered in selecting the major discharge sites. The development possibility of the discharging groundwater were estimated roughly, considering populations, industries and social development compatibilities of the selected areas. Groundwater dams and linked usage with surface water were suggested as possible development methods for the groundwaters.. Based on this study, we selected about 60 sites as the major discharge areas and tentatively recommended 6 sites as optimal sites for development of groundwaters being discharged into the sea. However, detailed in-situ hydrogeologic surveys are required prior to the final decision.

  • Designing a complex begins with plans to differentiate the archetypical place in accordance with environmental characteristics of the area where target programs and districts are to be located, with which the space reformed with the change and development of the era is established and shaped. In particular, in the area such as our domestic land, some 70% of which is inclined has adopted the design concept that uses slopes with the stream of times and has sought design strategies that consistently interpret and approach slopes. Taegwondo Park, the target of this study, has collected six draft design plans during the design stage with different values and thus strategies of utilizing topographies and spaces differentiated accordingly. Particularly, approaching strategies in accordance with geographical features by designer, the relationship between architecture and external space to be implemented according to the rank, philosophical understanding of architects and design strategies as the concept of iconizing the area carry significant implications as major design strategies explored by this study, through which I was able to identify the possibility of materializing the design strategy for hill lands.

  • This study is to validate the use of macro language for the land suitability analysis aiming to help to resolve land use conflicts. The silver-town suitability analysis is conducted on the Geejang Gun, Busan Metropolitan city. Such digital maps as terrain, road, facility, and water body were created for various cartographic models. A cartographic model identified the best suitable areas for silver-town development based on the such site selection variables as a distance to facility and road, slope and aspect of terrain, land use etc. Then, the other cartographic model identified the most favorable site among the candidate sites based on the comparison of the aspect of proximity, usage and environmental quality. Macro language was used for these modeling process and was used for the manipulation of all these spatial variables used in the models to resolve land use conflicts relating to the decision making process of the final site selection. This study will improve the effectiveness and rationality of the traditional site suitability analysis.

  • This study aims to identify appropriate tree species and crops for agroforestry target sites in North Korea based on ecological geography and site properties. To this end, an ecological geographic map (13 regions and 4 zones) of North Korea was made using satellite images and North Korean academic journal articles. The target agroforestry sites were selected and mapped according to 18 site conditions depending on 3 site characteristics, and the sites were divided into short-term and long-term target sites depending on the agroforestry management period. Finally, optimal combinations of 30 tree species and 19 crops were selected by overlapping the ecological geographic map and agroforestry target site map. For regions within the same zone, tree species and crops were almost similar; however, compared to regions in other zones, they differed. This is likely because the geographical climatic characteristics reflected in the ecological geographic map vary greatly from zone to zone. These results will be used to propose a combination of suitable tree species and crops that takes into account both management purposes and management types for inter-Korean forest cooperation in the agroforestry sector.

  • 하수관거 설계시나 단지개발사업, 그리고 하수관거정비사업과 같이 오수처리시설의 적정 규모 결정을 위해서는 정확한 상수사용량 및 오수발생량 원단위가 요구되지만 국내의 경우 이러한 원단위에 대한 기초자료 부족과 자료의 신빙성 결여로 인해 적정 원단위를 결정하는데 어려움이 있다. 이러한 관점에서 단지개발이 이루어지는 도시에서는 도시의 규모, 입지조건, 기후조건, 생활양식 등 다양한 요인들이 고려된 오수발생패턴 및 발생량 조사가 필요하며, 조사된 원단위는 오수처리시설의 적정 규모 결정뿐 아니라 침입수/유입수 분석 및 하수관거정비에 대한 성과예측에도 활용될 수 있다. 본 연구에서는 현재 단지개발 및 하수관거정비사업이 진행중인 하남시의 표본이 될 수 있는 대표구역을 선정하고 그 지역에서 조사지역을 세부적으로 분류하여 각 지역별 오수발생특성을 분석하였다. 대상지역인 하남시는 총면적의 $97\%$가 자연녹지 및 생산녹지이며, 나머지 $3\%$는 일반주거지역 및 일반 상업지역으로 나뉜다. 그리고 도시계획상 공장지역으로 편성된 부분이 없어 앞으로도 하남시 대부분의 면적이 녹지와 주거/상업지역으로 구성될 것이다. 이러한 하남시의 특성을 고려하여 조사지역은 공장지역을 제외한 일반주거지역, 밀집주거지역, 영업지역으로 분류하였으며 이렇게 분류된 지역은 각각 오수발생패턴 및 오수농도에 대한 조사를 실시하여 오수발생특성을 분석하였고, 조사지역별 인구수 조사와 연계하여 원단위 자료를 추출하였다. 이렇게 조사된 자료들을 통해 침입수/유입수 분석에 요구되는 오수전환율, 야간생활하수량 비율을 산정하였으며, 차후 단지개발 및 관거정비 후에 발생하는 오수 발생특성과 비교분석을 통하여 하남시 지역의 오수발생특성에 대한 신뢰성 있는 자료로 활용될 것으로 기대된다.

  • The purpose of this study is to examine the chracteristics of the location of Zen Buddhist temples which are the Nine-Mountain Sects of Zen(九山禪門) from feng-shui perspective. A large number of temples have been built for about 1600 years since Buddhism had influenced on Korea. They have been built nationwide in different times by different sects of Buddhism. The pattern of location of Buddhist temples is different according to background of the times (political, economic, cultural aspect) and of tenet(difference in sects of Buddhism) when the temples were built. But the general location of Korean Buddhist temples is in accordance with feng-shui theory. Feng-shui is a traditional geographic thought in China and Korea. It is necessary to understand feng-shui in order to understand Korean landscape and cultural geography. It had given a tremendous impact on Korean landscape through choosing site of cities, settlements, houses, mounments, temples, pagodas, and so on. Before feng-shui was prevailing in Korea, Buddhist temples were mostly built on sacred place which was connected with folk beliefs. In the case of the late Silla Dynasty when Zen Buddhism was prevailing, feng-shui became popular and many. temples were built in accordance with feng-shui. The typical examples are found in the site of Nine-Mountain Sects of Zen temples. The interpretation of geomantic site of Nine-Mountain Sects of Zen temples will show us how feng-shui was applied to and reflected in the Korean peninsula. In Zen Buddhism, feng-shui was applied to the choice of the temple site. Also feng-shui theory was usually used to choose the site of stupa(Budo) where the remains of the founder of sect. In this study, I will interpret the geomantic characteristics of Nine-Mountain Sects of Zen temples. The geomantic interpretations of the temples are as follow. 1. The temples are located at the foot of a hill with surrounding mountains and a watercourse in front. Feng-shui texts often describe it as an ideal site. This geomantic situation is well equipped with natural drainage; protection from cold wind from the north or evil spirits; a good view with open space to the front; protection from unnecessary weather damage; and security and protection from strangers and invaders. 2. The sitting and facing direction of the temples correspond to the oncoming dragon's direction. 3. Many feng-shui texts discuss the types of Sa(surrounding mountains) in detail and morphologically describe them with certain animate and inanimate auspicious objects. In case of Nine-Mountain Sects of Zen temples, the geomantic landscape of these can be compared to auspicious objects. This is morphological marker for the description of configulation features of these temples. 4. Most auspicious places are not perfect, but the shortcomings can be overcome by many means. We can observe modification of landscape for the purpose of fulfilling the geomantic harmony of the temple.
