한국산 최서남단에 위치하는 소흑산도일대에 분포하는 개미상을 조사하기 위하여 1994년 4월과 7월 조사한 결과 537 colony의 표본을 채집하여 동정함으로서 소흑산도에 분포하는 37종의 개미상이 처음으로 밝혀졌다. 37종중 긴털톱니비늘개미(신칭) Smithistruma inceria Brown와 나도네눈개미(신칭) Camponotus nawai lto는 한반도에서는 처음으로 그 분포가 밝혀졌다.
One of the most destructive forces around greenhouses is wind. Wind loads can be obtained by multiplying velocity pressure by dimensionless wind force coefficient. Generally, wind force coefficients can be determined by wind tunnel experiments. The wind force coefficient distribution on a single - span arched greenhouse was estimated using experimental data and compared with reported values from various countries. The results obtained are as follows : 1. The coefficients obtained from this study agree with the values proposed by G. L. Nelson except about 0.5 of difference in the middle region of roof section. This discrepancy is mainly attributed to the dissimilarity of experimental conditions (or wind tunnel test such as Reynolds number, type of terrain, surface roughness of model, location of the lapping and measuring methods. 2. Considering that the wind force coefficients are varied along the height of a wall at wind direction perpendicular to wall, structural analysis using subdivided wind force coefficient distribution is more resonable for wall. 3. It is recommendable that wind force coefficient distribution on a roof should take more subdivision than the existing four equal divisions for more accurate structural design. 4. Structural design using wind forces close to real values is more advantageous in safety and expense.
