  • With regard to the pavilion buildings of Imcheonggak Gunjajeong and Donglakdang Gyejeong that are located within residential areas, this study focused on the construction background, the building owner's circumstances and the location environment of these buildings, and attempted to derive the architectural characteristics presented by these two pavilion buildings and, through this, to grasp the architect's intention of plan. The results of this study are as follows. With regard to Gunjajeong, it could be confirmed that, first, it is located in a propitious site and took the composition that follows the family ritual standards for the family rituals of the scholar-gentry class and opens to visitor access, and second, the floor height of the site and interior space was designed so that Munpilbong on the south and the Sarangchae on the west, and the Sadang on the east can be connected visually, and third, the authority and dignity of the head family were built through the symmetric 丁-shaped plane figure, the wide partition module, the form-centered building, and the hierarchical composition of the roof. On the other hand, with regard to Gyejeong, it could be confirmed that, first, it is located along the stream of Jagye valley that has no mountains in the front and in the back and took the composition that put the name symbolizing Taoist thoughts on the surrounding natural environment and was closed to visitor access but opens to nature, and second, with Jagye and Jagye surroundings as the main landscape, it built the concept of intended landscape that symbolizes the Taoist thoughts by giving names not only simply to the visible objects but also to surrounding rocks, and third, the asymmetric ㄱ-shaped plane composed a yard-centered space rather than emphasizing the shape, and connected the part of the plane with Jagye so as to be embodied as a personal inner self-perfecting place that closely communicates only with nature away from the mundane world.

  • 광주시 월각산 (275 m)의 계곡 주변에서 관중과의 남방고사리속과 관중속에 포함되는 미기록 양치식물 세 분류군을 발견하였다. 흰비늘고사리 [Ctenitis maximowicziana (Miq.) Ching]는 엽병 기부 인편의 색깔과 형태, 엽신의 형태, 둥근 신장형의 포막의 유무 등의 특상에 의해 남방고사리 [C. sinii (Ching) Ohwi]를 포함한 속내 다른 분류군들과 식별되었다. 남도톱지네고사리[Dryopteris lunanensis (H. Christ) C. Chr.]는 측우편의 수, 중부 이하의 우편의 제 1열편 혹은 2열편의 분열정도와 포자낭군의 분포양상에 의해 유사 분류군인 톱지네고사리 [D. atrata (Wall. ex Kunze) Ching]와 구별되었다. 애기지네고사리 [Dryopteris decipiens (Hook.) Kuntze var. diplazioides (H. Christ) Ching]는 중부 이하 우편의 분열 정도에 의해 원변종 var. decipiens와 식별되었으며 잎의 형태로 볼때 원변종과 큰지네고사리 (D. fuscipes C. Chr.)의 중간형처럼 보였다. 이들 세 분류군은 월각산의 해발 200-250 m에 국한하여 10개체 내외가 자생하고 있었다.

  • In order to clarify the relation between sea breeze penetration and Planetary Boundary Layer development in southeastern part of the Korean Peninsula, several numerical assessments were carried out using atmospheric numerical model WRF(Weather Research and Forecasting). Compared with onset time of sea breeze at eastern coast area(Uljin), the time at southern coast region(Masan) with complex costal line tend to delay for several hours. The penetration patterns of sea breeze between two coastal regions are some different due to the shape of their coastal line and back ground topography. Intensified valley wind due to high topography of lee side of Uljin can help penetration of sea breeze at early time. So penetration of sea breeze at early time often prevent PBL to develop at Uljin and lower PBL height last for a day time. But because of late penetration of sea breeze at Masna, PBL Height dramatically decrease after 1500LST. The distribution of front genesis function based on the heat and momentum variation are explained obviously the sea breeze penetration patterns and agreed well with the PBL height distribution.

  • 본 연구에서는 절곡 깊이(1.4 mm)와 절곡 핏치(5.5 mm)가 같은 둥근 웨이브와 각진 웨이브 핀-관 열교환기에 대한 실험을 통하여 절곡 형상이 전열성능에 미치는 영향을 검토하였다. j 인자의 경우 둥근 웨이브 핀이 모든 열수에서 1.2~22% 크고 f 인자는 3열의 경우 8.3~23% 크고 1, 2열의 경우는 -1.0~29% 작다. 둥근 웨이브 핀이 우수한 성능을 보이는 이유로 둥근 웨이브 핀의 경우 각진 웨이브 핀 보다 유동이 핀의 곡면을 잘 따라갈 수 있으므로 골에 존재하는 재순환 영역의 크기가 줄어들기 때문으로 판단된다. 둥근 웨이브 핀의 경우 핀 핏치가 j와 f 인자에 미치는 영향은 크지 않다. 또한 j 인자는 튜브 열수가 증가할수록 감소하는 반면 f 인자는 튜브 열수와 무관하다. 실험 데이터로부터 새로운 상관식을 도출하였다.

  • The Korean rural landscape has changed significantly due to nationwide modernization and industrialization in recent years. Moreover, as urbanization progresses due to population and economic growth, rural areas surrounding the suburbs of cities are feeling the pressure of encroaching urban sprawl. Use of land for human-made structures such as road and housing development is also increasing, resulting in the destruction of nature in rural areas. Adopting a concept of conserving rural landscape in future development projects is therefore highly desirable.The main focus of this study is to look into the traditional concept of the village and to classify some elements of the traditional rural landscape. Daegu Metropolitan City, the third metropolitan city in Korea, is chosen as the subject of the study. The existing 227 villages have been studied on the basis of their principles and types of village locations in relation to the traditional concepts of 'Feng-shui' and 'Tackriji'. The characteristics of the village location are divided into two aspects: the natural landscape, such as topography, hydrosphere, and azimuth, and the historical and cultural landscape, such as customs(Only the natural landscape aspect is included in this study). The natural landscape, a condition of the village location, is divided into three areas: topography, hydrosphere, and azimuth. There are two types of topography: flatland type and mountain type. There are two sub-types in the mountain type: ridge and valley, which depend on the village location in relation to the shapes of the mountains. There are four types of hydrosphere which include waterways and three directions of mountain depending on the shape: front, behind and side. The direction of the village is analyzed from the direction which the houses in the village face. Therefore, the natural landscape element as a condition of the village location is closely related to the traditional concepts of the village.

  • Rapid and reckless economical development is causing nationwide deforestation; more and more forest is being developed to be used as a base for economic advancement. While benefiting the national economy, this destruction of forest is creating a serious problem in the National Land Plan. To solve this problem, it is imperative to understand the current condition of damaged forest and make an environment-friendly plan. This paper explains the principles of spatial plan and sets the criteria for the plan, such as patch size, connectivity, and edge of the Landscape Ecology. The paper assesses the conservational value of area that are currently being developed or planned to be developed to figure out the current environmental situation. This conservational value was verified by the field survey. The result of assessment appears that the patch size of the major mountains in site is over 1,000ha and edge is located widely beside roads. The area of the high connectivity is located agriculture area in valley or narrow roads. The research shows that the patch size is related to biodiversity the larger the patch size, the more populated the species are. The research also reveals the conservational value indicated by degree of connection to forest, difference in the structure of vegetation between core area and edge area, and effects of surrounding environment. In further study, we will assess other criteria of conservation value, such as patch shape and fragmentation to the Landscape Ecology, and apply those criteria in biological aspects of the spatial plan.

  • Eranthis stellata Maxim. is a perennial plant that grows around the valley. E. stellata is concerned about the decline in natural habitats due to climate change in KOREA, continues to be observed and protected as an endangered species (Least Concrned, LC). Nevertheless, studies on the characteristics of the seeds of E. stellata are insufficient. So, this study analyzed the morphological characteristics and dormancy types of seeds. Seeds of E. stellata was collected in April at Gyeongsangbuk-do Arboretum and kept at 5 ℃ until using. To investigate the morphology of seeds, an optical microscope and a scanning electron microscope (SEM) were used. GA3 treated or untreated seeds (4 replicates of 25 seeds each) were observed germination and embryo growth for 1 month at 5 ℃ and 25/15 ℃ (12h day/12h night). The seed surface of E. stellata, light brown, was observed as a common characteristic of Eranthis genus, reticulate. The short axis of seeds was 1.11~1.77mm (average 1.44mm), and the long axis was 1.27~1.91mm (average 1.63mm), which was investigated in a slightly round shape (subglose). While no germination was observed at all conditions, Embryo growth was observed at 5 ℃ both in the control group and with GA3treated groups. Thus, seeds of E. stellata are classified as morphological physiological dormancy (MDP), which requires embryonic development and dormant break at the same time. These results can be useful information for determining morphological physiological seed dormancy and germination, and will be an important basic data for seed propagation of E. stellata as a resource.

  • 이 연구는 울릉도 나리분지 추산용천수의 유동 경로를 파악하는 것이다. 칼데라 내부 가장자리를 따라 발달하는 단층과 단열구조들의 발달 방향이 추산용천수 유동 경로에 영향을 주는 요소로 파악되었다. 추산용천수는 함양된 지하수가 동서 방향과 남북 방향의 단열대를 따라 추산용출소 방향으로 흐른다. 이와 더불어 북북동 방향으로 경사진 칼데라의 부등함몰의 영향으로 북동 내지 북북동 방향으로 흐르는 것으로 파악되었다. 장내세균과인 Entrobacteriaceae을 이용하여 나리지하수 쪽의 물이 추산용출소 방향으로 유동하는 것으로 파악되었다. 다만, 분석에 사용된 시료수가 매우 적어 성인계곡수로부터 나리분지와 추산용출소까지의 유동경로를 전체적으로 파악할 수 없다는 제한성이 있다.
