비구조적 퍼지 의사결정지원시스템을 활용한 건설재해 예방대책에 관한 연구
이용준,정성춘,이학기 東亞大學校 建設技術硏究所 2004 硏究論文集 Vol.27 No.2
The hazard factors in building construction project are various and their bad effects with regard to project's efficiency are increasing due to its enlargement and complexity. However. the assessment of the construction safety is commonly dependent upon the statistical and historical information. since the existing systematic tool assisting to the effective decision making for estimating the safety prior to construction phase is inaccurate. In addition. it is true that there are the various difficulties to analyze and diagnosis the construction safety with the probabilistic approach. because there are the many vague factors and limited resources. Therefore. the purpose of this research is to provide the way to establish the efficient preventable countermeasure against the hazard factors. corresponding to the category of the hazard characteristic. by using non-structural fuzzy decision support system for diagnosing effectively the construction project safety.

목적 : 기관지내시경 검사에서 흔히 사용되는 국소마취제인 lidocaine과 내시경시 지혈목적으로 사용되는 thrombin과 epinephrine이 각종 균주에 미치는 항균효과에 대해 알아보고자 하였다. 재료 및 방법 : 균주는 가톨릭대학교 성모병원에서 2004년 3월부터 2004년 9월까지 임상검체 에서 동정된 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 각각 42, 42, 42, 43주를 대상으로 하였다. Lidocaine, thrombin, epinephrine 감수성 검사는 National Committee for Clinical Laboratory Standards (NCCLS, 2002)의 기준에 따랐다. 결과 : Lidocaine은 S. aureus, S. pneumoniae, P. aeruginosa에서 MIC_(50), MIC_(90) 모두 20,000 ㎍/mL 이었다. K. pneumoniae는 각각 10,000 ㎍/mL이었다. Thrombin은 S. aureus와 P. aeruginosa에서 MIC50 500 lU/mL 과 MIC_(90) 500 IU/mL 이상이었고, K. pneumoniae에서는 MIC_(50)과 MIC_(90)이 모두 500 lU/mL이상이었으나 S. pneumoniae에서는 MIC_(50)과 MIC_(90)은 125 IU/mL이었다. Epinephrine은 K. pneumoniae, S. pneumoniae에 대한 MIC_(50), MIC_(90)가 모두 >500 ㎍/mL이었고, S. aureus와 P. aeruginosa에 대한 MIC_(50), MIC_(90)가 모두 500 ㎍/mL이었다. 결론 : 기관지 내시경 검사에서 흔히 쓰이는 lidocaine, thrombin, epinephrine 등의 약제들이 호흡기 질환의 흔한 병원균인 S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa 균주들에 대해 항균 효과가 있을 수 있어 세균배양검사에 영향을 미칠 수 있겠다. Background : We performed this stody to find out about antimicrobial effect of lidocaine which is commonly used local anesthetic, and thrombin and epinephrine used for hemostasis during bronchoscopic procedures. Materials and Methods : The microorganisms that were cultured from specimens obtained during bronchoscopy were Staphylococcus aureus (n=42), Streptococcus pneumoniae (n=42), Klebsiella pneumoniae (n=42), and Pseudomonas aeruginosa (n=43) collected from St. Mary's Hospital, from March to Sep 2004 were used for susceptibity testing. Susceptibility to lidocaine, thrombin, and epinephrine were tested according to the National Committee for Clinical Laboratory Standards. Result : MIC_(50) and MIC_(90) of lidocaine for S. aureus, S. pneumoniae, P. aeruginosa were all 20,000 ㎍/mL and that for K. pneumoniae were 10,000 ㎍/mL. MIC_(50) and MIC_(90) of thrombin for both S. aureus and P. aeruginosa was 500 IU/mL and above 500 IU/mL, respectively; that for K. pneumoniae were all above 500 IU/mL and for S. pneumoniae they were 125 IU/mL, MIC_(50) and MIC_(90) of epinephrine for K. pneumoniae and S. pneumoniae were above 500 ㎍/mL; that for S. aureus and P. aeruginosa were 500 ㎍/mL. Conclusion : We observed possible antimicrobial effect of lidocaine, thrombin, and epinephrine in vitro against pathogens such as S. aureus, S. pneumoniae, K. pneumoniae, P. aeruginosa, which are common respiratory microorganisms. The use of these agants could affect the result of bacterial culture.

In this work, we report on the investigation of the properties of cyclohexane-based plasma polymers (CHexPP) as functions of the deposition pressure and the plasma power. As the deposition pressure was decreased from 2 torr to 0.2 ton with a fixed plasma power of 60W, k value of the CHexPP thin film increased from 2.42 to 3.24. CHexPP thin films deposited at lower deposition pressure showed very good thermal stability, even the one deposited at 0.2 torn was stable up to 400℃. As the plasma power was increased from 10W to 90W with a fixed deposition pressure of 0.2 ton, k value increased from 2.61 to 3.39. The CHexPP thin film deposited at 90W were stable up to 450℃. All the deposited films were insulating. Under applied fields less than 1 MV/cm, leakage current densities were less than 10^-7 A/㎠.

Studies on Mycological Characteristics and Composition Analysis for Breeding Wolfiporia cocos
Sung-Hak Lee,Seung-Ho Shin,Woo-Ram Park,Seung-Chun Park,Woo-Sik Jo 한국버섯학회 2017 버섯 Vol.21 No.2
This study was carried out to determine the basic mycelial culture conditions for Poria cocos growth. According to colony diameter and mycelial density, suitable media for mycelial growth were Malt yeast extract, Potato dextrose agar, Yeast extract agar, and Yeast malt agar. The optimum temperature for mycelial growth was between 25 and 35oC, and the optimum pH value was between 4 and 7. Carbon and nitrogen sources were fructose and yeast extract. The optimum C/N ratio was about 10 to 1 with 2% glucose. Other minor components for optimal growth were thiamine-HCl and nicotinamide as vitamins, acetic and lactic acid as organic acids, and MgSO4·7H2O and FeSO4·7H2O as mineral salts. Wolfiporia cocos is a well-known traditional medicine in China, Japan, Korea, and other Asian countries owing to its numerous therapeutic properties. With the aim to determine the morphology and genetic characteristics of W. cocosten strains of W. cocos were cultivated in vitro, and subsequently, rapid amplification of polymorphic DNA was performed. To the best of our knowledge, this is the first study to examine the morphology of fruit bodies of W. cocos in Korea. W. cocos were cultured on PDA agar at different temperatures (12, 16, 20, 24, and 28oC) under 12-hour light (600 Lux) / 12-hour dark photoperiod condition for 1 month. Appearance of fruit body was the highest at 28°C condition in all the strains investigated. Honeycomb-like structure on sclerotia was observed in Andong 01, Andong 02, Andong 03, KFRI 1104, KFRI 1105, KFRI 1106, KFRI 1107, KFRI 1108, and ASI 13007 strains. The KFRI 1103 strain formed cosmos petal-like structure on sclerotia. The average size of basidiospores was recorded as 7.55 μm in height and 3.35 μ in width. This study was carried out to discriminate the geographical origin from Korea and Chinese Wolfiporia extensa. By proximate composition analysis, both were identified as similar, showed oxygen was 45.32-48.07%, carbon was 38.09-40.12%, hydrogen was 6.05~6.78% and nitrogen was 0.16-0.23%. Antioxidant activity was examined by DPPH free radical scavenging activity. No significant differences were found as well for the antioxidant activity between Korean and Chinese product. However, the contents of inorganic components ED-XRF (X-Ray Fluorescence Spectrometer) were significant different in Chinese and domestic W. extensa. The Potassium and iron in Chinese and domestic W. extensa were 47.60±8.78% and 14.5±3.86% as well as 33.14±17.27% and 9.13±4.83%, respectively. From the above resuls, the analysis of inorganic components by ED-XRF may be used for discrimination of the geographical origin of W. extensa.
