Time, place, and the high-tech industry to overcome barriers to the fusion of the so-called "smart agriculture" is changing the landscape of agriculture. Precision Agriculture's core temperature, humidity, location information, and summary information in real time, all significant ICT controlling technique. The system is a four-season container production for the mushroom cultivation temperature, humidity, illumination, self-regulation, such as carbon dioxide, the optimal environment for mushroom cultivation was implemented. Hericium erinaceum (also called Lion's Mane Mushroom, Bearded Tooth Mushroom, or Bearded Tooth Fungus) is an edible mushroom and medicinal mushroom in the tooth fungus group. Native to North America, Europe and Asia it can be identified by its tendency to grow all the spines out from one group (rather than branches), long spines (greater than 1 cm length) and its appearance on hardwoods. About 40 days of incubation 1.5kg oak sawdust was used as the test medium bag. The humidity was maintained more than 85~95% and temperature was 18~20°C, and CO2 density was 500~1,000ppm. The days for primordium formation showed us 6~12 days. The amount of fruitbody production was 110~260g per bag. This technique to establish new community support program in conjunction with the international movement, domestic sales and exports are also planned.

Penicillium rubrum에 의한 상황버섯 (Phellinus baumii) 푸른곰팡이병의 발생
조우식 외 한국버섯학회 2007 한국버섯학회지 Vol.5 No.1
본 연구에서는 상황버섯 (P. baumii)의 자실체에 발생하는 Penicillium sp.균을 동정하기 위하여, 분리균의 배양적·형태적 특징을 조사하였다. 분리된 Penicillium sp.의 형태적 특성을 조사한 결과, 분생포자의 모양은 타원형이고 직경이 1.8∼2.3 ㎛ 크기로 분생포자를 많이 형성하였다. 분생포자경은 균사로부터 one-stage branch 모양을 형성하였고, matulae는 3∼5개로 길이가 5.2∼7.8 ㎛이며, phialide는 플라스크상이고 크기가 5.7∼7.5×2.2∼2.7 ㎛이였다. Czapek's agar 배지에서 생육시 25℃에서 8일간 균체가 23 ㎜ 생장하였다. PDA 배지 상에서 균총의 형태는 처음에는 조밀한 솜털모양의 백색을 띄었으며 차츰 기중균사가 형성되었고, 점차 회녹색으로 변하였다. 이상과 같은 형태 및 배양적 특징으로 이 균을 P. rubrum으로 동정하였다. 상황버섯 (P. baumii)에서 P. rubrum에 의한 병은 아직 국내에 보고된바 없어, P. rubrum에 의한 상황버섯 (P. baumii) 푸른곰팡이병을 최초로 보고한다. Green mold of Phellinus baumii mushroom caused by a species of Penicillium was observed in Daegu on August, 2000. The causal fungus was identified as Penicillium rubrum based on its cultural and morphological characteristics. Conidiophores of the fungus were one-stage branched and terminating in a whorl of 3∼5 metulae. The metulae were mostly 5.2∼7.8 ㎛ in size. Phialides were flask-shaped and 5.7∼7.5×2.2∼2.7 ㎛. Conidia were subglobose and 1.8∼2.3 ㎛. Colonies on Czapek's agar growing, attaining a diameter of 23 ㎜ within 8 days at 25℃. The optimum temperature for growth of the fungus was about 20∼30℃. This is the first report on the occurrence of green mold of P. baumii caused by P. rubrum in Korea.
비접촉식 측정데이터를 이용한 근사 곡면 생성 및 영역화

As well known, the non-contact measuring method via the laser scanning or vision system provides vast amount of measuring points by which we rapidly identify the overall shape. On the other hand, its measuring accuracy (resolution) may be lower than that of touch probing method. From the reverse engineer's point of view, it is meaningful and efficient to fully utilize the merits of each methodology. This paper describes the construction of an overall approximate surface model by the non-contact measurement data (cloud-of-points), and the segmentation scheme for identifying sub-areas which should further be digitized by a scanning touch probe. The segmentation is performed through extracting the featured boundary edges or shapes (sharp edges or blend surfaces) by a pencil curve tracing algorithm.

정용희,류미숙,김영식,이우인,이희주,서환조 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.1
Eikenella corrodens is a slowly growing, facultative anaerobic gram-negative bacillus. It is a normal inhabitant of the human upper respiratory tract, and it is recognized as an infrequent cause of invasive disease. To date, a few cases of E. corrodens infection were noted from all other organ. We report herein two cases of E. corrodens infection. In one case E. corrodens was isolated in the lung abscess and in the other case it was in the appendiceal abscess. The patients were treated empirically with penicillin G. The results of the bacterial culture and sensitivity test were available with it. The patients were discharged 15 days later with marked improvement after treatment. Our report clearly demonstrates that E. corrodens can be the pathogen of lung abscess and intraabdominal abscess. We reviewed descriptions from the literature of infections caused by E. corrodens.
