표고 재배사내 진균류의 발생특성을 분석하기 위해 골목에서 발생한 진균류를 분리·동정하고 재배사내 온·습도 환경을 분석하였다. 표고골목에서 발생한 진균을 분석한 결과 Cladosporium sp., C. cladosporioides, C. anthropophilum, Pleosporales sp., Trichoderma harzianum, Acremonium sp. 6종으로 확인되었다. 재배사내 환경을 조사한 결과는 5월 1일부터 10월 12일 사이에 재배사내 최고·저 온도가 14.0~30.1℃, 평균습도는 82.8%으로 나타났다. 이러한 결과는 표고 재배과정 중 진균류의 발생이 활발한 초여름부터 가을철 사이에 철저한 재배관리가 중요하며, 한번 발병한 진균류는 연중 재배사내 생존이 가능하기 때문에 주기적으로 모니터링하여 사전에 유해 진균류 발생에 유리한 생육환경을 예방해야 한다. We monitored the occurrence of fungal species on bed-logs inoculated with oak mushroom (Lentinula edodes) and the environmental conditions of temperature and humidity in the cultivation houses during monsoon. Six fungal species, viz., Cladosporium sp., C. cladosporioides, C. anthropophilum, Pleosporales sp., Trichoderma harzianum, and Acremonium sp., wereidentified from the cultivation houses located in Jangheung, Jeonnam province. This identification was confirmed by performing nucleotide sequence analysis of the internal transcribed spacer and 28S rDNA regions. Our study presents significant findings that can help in preventing fungal damage induced by inappropriate temperature and humidity in oak mushroom cultivation houses.
신경과 의사 공급의 현재와 미래: 우리에겐 신경과의사가 충분히 있는가? - 급성 뇌졸중 치료를 중심으로

Korea is one of the fastest aging country in the world. As the old population increases, incidence of stroke would rapidly increase. We estimated future of the neurologist supply in Korea, and assessed whether the present neurologist supply is appropriate to cope with future increase of stroke. We reviewed the resource database of neurologists affiliated to Korean Neurological Association. Age, sex, location of workplace, and work positions were identified. The stroke incidence was calculated from age group specific incidence data and projected age group number. Age group specific incidence data was adapted from the 2006 report of the Construction of National Surveillance System for Cardiovascular and Cerebrovascular Disease. Total 1,828 neurologists in practice were identified. Six hundred and fifty-five (30%) worked in training hospitals. 457 (21%) in other general hospitals, 305 (14%) in private clinics, and 148 (7%) worked in nursing hospitals. Assuming that the neurologists are trained 82 people per year as in the present, 2,073 neurologists would be present in 2020, 2,659 in 2030. However, stroke incidence would show more rapid increment, and is expected about 170,000 per year in 2020 and 300,000 per year in 2030. Therefore, there will be a shortage of neurologists needed for stroke care in the future. Because of rapid increase in the elderly population, current supply of neurologists may not meet the expected need for stroke care. Therefore, national health system needs more neurologists to cope with that situation.
