골프장의 잔디 토양에서 살균제 Tolclofosmethyl의 분해
정근욱,우선희,김흥태,사동민,김영기,홍순달,김재정,이재구 한국환경농학회 2004 한국환경농학회지 Vol.23 No.3
Tolclofosmethyl (TCFM) is heavily and annually applied to the turf soils of most golf courses in Gyeongju to control the fungi known to cause the disease brown patch. The soil samples used for the experiment was collected three weeks after the annual application at the end of May in the year 2002. The preliminary results obtained from this study demonstrated that the repeated field annual applications of TCFM to the turf soils of a golf course located in Gyeongju city in the southern area of Korea showed the enhanced degradation of the parent compound TCFM, especially in the surface (0~15 cm) soil rather than the shallow subsurface (15~30 cm) and deep subsurface (30~45 cm) soils, compared to the corresponding surface (0~15 cm) and shallow and deep subsurface (15~30 cm and 30~45 cm) soils of the untreated plot. It appears that microorganisms in the soil may be involved in the enhanced degradation of TCFM.

This study was done to observe the distributions of Oxytocinergic and Vasopressinergic neurons in the hypothalamus of the cow. For the immunohistochemical staining, sections were reacted with the following sequence of solutions: monoclonal anti-vasopressin and anti-oxytocin, biotinylated anti-mouse IgG, avidin-biotin peroxidase complex, and Ni-DAB. The results observed under light microscope were summarized as follows. Our immunohistochemical investigations reveal both vasopressinergic and oxytocinergic neurons in the supraoptic nucleus(SON), paraventricular nucleus(PVN), accessory supraoptic nucleus (ASN), periventricular nucleus(PN), suprachiasmatic nucleus(SCN), and arcuate nucleus(AN), but these two types of neurons were mainly distributed in the PVN and SON and the ratio of the number of vasopressinergic neurons to that of oxytocinergic neurons was 1:1.30 in the PVN, and 1:1.00 in the SON. These two types of neurons were round, oval and spindle-shaped and cell size was 30-55um.
Development of On-Line Health Monitoring System for Pipes in Nuclear Power Plants
Eom, Heung Seop,Lim, Sa Hoe,Kim, Jae Hee,Kim, Young H.,Kim, Hak Joon,Song, Sung Jin Trans Tech Publications, Ltd. 2006 Key Engineering Materials Vol.321 No.-
<P>This study was aimed at developing an effective method and a system for on-line health monitoring of pipes in nuclear power plants by using ultrasonic guided waves. For this purpose we developed a multi-channel ultrasonic guided wave system for a long-range inspection of pipes and a few techniques which can effectively find defects in pipes. To validate the developed system we performed a series of experiments and analyzed the results.</P>

본 연구는 2인의 전문의와 함께 의료 문헌의 초록을 분석하여 의료문서에서의 절차적 지식을 모델링하고 텍스트 마이닝 기법을 적용하여 절차적 지식을 추출하는 방법론에 대해 기술한다. 절차적 지식은 목적과 해법의 묶음으로, 해법은 다시 단위 절차 지식의 네트워크로 정의 하였고, 목적과 해법 정보 추출과 단위, 절차 지식의 구성요소인 대상/행위/방법 개체를 인식하기 위해, 품사태깅, 구문분석, 술어-논항구조(Predicate-Argument Structure), 온톨로지 용어 매핑 정보 등에 기반한 기계학습 방법을 사용하였다. 실험을 위해 전문의와 함께 위암과 척추질환에 대한 1309 문서에 절차적 지식 태깅을 수행하였고, 이 문서 집합을 기반으로 목적/해법 추출 작업과 단위 절차 지식(대상질병/행위/적용방법) 추출 실험을 수행하여, 각각 82%와 63%의 F-measure 값을 얻을 수 있었다.
