...recorded, belonged to 25 taxa, which included 13 families, 19 genera and 25 species. In addition, 183 taxa were found on Mt. Dreogyu, which belonged to 37 families, 101 genera, 1 subsp. and 1 var. The habitat of each collection was examined and the classification system of Ignatov et al. (2006) was used. New vernacular names of 6 families and 11 genera were then determined.

[학술논문] 생물계절 상 분석을 통한 Level 3 type 북한 토지피복 특성
본 연구의 목적은 Level 3 type 북한 토지피복도를 작성하고 생물계절 특성을 파악 하는 데 있다. 2008년과 2009년에 촬영된 88장과 8장의 MODIS NDVI를 MVC 하여 질이 향상된 영상에 ISODATA 알고리즘을 적용하였다. 생물계절 상 분석을 기반으로 북한의 토지피복도를 구축하고 중분류에 대해서는 정확도 검정을 하였다. 결과, 총 27개 클래스의 북한 토지피복도가 생산되었다. 토지피복은 17개의 산림 서식지, 토지이용은 7개의 농경지와 2개의 시가지, 그리고 한 개의 수역을 포함한다. Level 3 type 생물계절 특성은 휴지기(σ^2= 0.348)와 식생이 급격히 생장하는 봄철(σ^2 = 0.347)의 역동성이 가장 컸다. Level 2 type에 대한 정확도 검정에서

...techniques have become an important tool for extraction of climatic and environmental factors, including rainfall, temperature, surface water, soil moisture, and land use, which are directly linked to the habitat qualities of malaria mosquitoes. Improvement of sensor fidelity with higher spatial and spectral resolution,new multinational sensor development, and decreased data cost have nurtured diverse remote...

...ginsengs. It is currently ascertained that the ginseng field size of Geumsan in early modern era was around 30,000 pyong in 1908, which grew into approximately 70,000 in 1910. Geumsan became the biggest habitat of white ginseng around this time and its production has steadily increased into the colonial period. The farming population has dramatically jumped from about 400 in early 1920s to 1800 in 1930s...
[학술논문] Influences of Human Residence and Environmental Factors on Malaria Incidence in Korea
The number of malaria cases has been undulating for the past 10 years in Korea since the reemergenceof malaria in early 1990’s. Considering the spatial variations of malaria incidence across the northmost borderareas near the demilitarized zone (DMZ), the occurrence of the disease seems to be influenced by the natural andhuman environment in the region. Malaria is an infectious disease that is
