본 연구는 부존 조사료자원의 이용을 활성화하여 수입사료를 줄이고 가축 사료비를 절감하고자 2010년도에 경기 파주 (민통선 지역)와 경기 안산 (시화지구)에서 갈대와 억새 등 야초자생지를 탐색하고, 수확?이용실태 조사와 함께 사료가치를 분석하였다. 파주 민통선 내억새 (Miscanthus sinensis)와 갈대 (Phragmites communis) 혼합 자생지는 90~100 ㏊ 규모로, 1차 곤포작업으로 사일리지 520톤 (㏊당 6톤), 2차로 380톤 (㏊당 4톤)을 조제하여, 연 사일리지 900톤 (㏊당 10톤)을 생산하였다. 곤포의 유통가격은 롤당 52~55천 원으로 ㎏당 130~137.5원이었다. 곤포는 자가소비 50~70%, 판매유통 30~50%로, 수익성은 인건비 정도로 추정되었다. 초장 70 ㎝의 재생 억새는 조단백질 9.6%, 상대사료가치 82.4 (건초 4등급), 건물 소화율 67.7%, 초장 70 ㎝의 재생 갈대는 각각 13.8%, 84.3 (4등급), 67.9%로 사료가치는 높았으며, 수확이 늦어짐에 따라 사료가치는 크게 낮아졌다. 안산 시화지구 (3공구)의 갈대 등 야초류자생지는 100 ㏊ 정도로 2009년도에는 50 ㏊에서 사일리지 550톤 (㏊당 11톤)을 생산하여 롤당 50천 원에 유통하였으며, 2010년도는 잦은 강우와 장마로 부분 이용에 그쳤다. 고초기의 갈대는 건물률 89.8%, 조단백질 2.2%, NDF 80.6%, ADF 55.4%, 상대사료가치 52.9 (5등급), 건물 소화율 36.4%로 볏짚에 비해서도 사료가치는 크게 낮았다. 초장 80 ㎝의 재생 갈대는 조단백질 12.9%, 상대사료가치 99.8 (3등급), 건물 소화율 66.6%로 사료가치는 양호하였으며, 개화기의 초장 150 ㎝ 갈대는 조단백질 4.5%, 상대사료가치 59.9 (5등급), 건물 소화율 42.2%로 볏짚의 사료가치와 비슷하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거?이용하되, 사료가치를 유지하고 가축 기호성을 고려한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전 (늦어도 7월까지)에 수확?이용하는 것이 권장된다. 본 연구에서 조사된 대부분의 야초류는 상대사료가치가 75 이하인 건초 5등급으로 사료가치는 매우 낮았으며, 키가 작은 영양생장기에 수확한 경우에만 4등급으로 나타났다. 부존 조사료자원의 이용은 양질의 사료작물 생산과 병행하여 추진하는 것이 바람직하였다. This study was carried out in 2010 to investigate the utilization and nutritive value of native grasses, such as Phragmites communis and Miscanthus sinensis which might reduce the cost of feeding domestic cattle. The regions within the Civilian Control Line in Paju and Sihwa region in Ansan were surveyed. In Paju, the yearly silage production was 900 MT harvested from 90 ha (10 MT/㏊). About 30~50% of these were sold out at the marketing price of 52,000~55,000 Won per roll (130~137.5 Won/㎏). Regrown Miscanthus sinensis of 70 ㎝ in length contained 9.6% of crude protein (CP), 82.4 of relative feed value (RFV), and 67.7% of in vitro dry matter digestibility (IVDMD). Regrown Phragmites communis of 70 ㎝ in length contained 13.8% of CP, 84.3 of RFV, and 67.9% of IVDMD. As harvesting was delayed, the quality was decreased dramatically. In Ansan region, Phragmites communis plantation covers 100 ha. The silage production was 550 MT from the area of 50 ha (11 MT/㏊) in 2009. And the marketing price was 50,000 Won per roll. But in 2010 only a small amount of grasses could have been baled due to frequent and much rainfall from spring to summer season. However, the good forage quality was observed from regrown Phragmites communis of 80 ㎝ in length, 12.9% CP, 99.8 RFV and 66.6% IVDMD, while that of late matured grasses was very low, 2.2% CP, 52.9 RFV and 36.4% IVDMD, greatly lower than forage quality of rice straw. The quality of grasses at bloom stage of 150 ㎝ in length was similar to that of rice straw, showing 4.5% CP, 59.9 RFV and 42.2% IVDMD. In conclusion, the overall quality of most native grasses in this survey were very poor. Therefore, we recommend that Phragmites communis and Miscanthus sinensis should be harvested during June or July to obtain better forage quality which is richer in forage values than rice straw. Production of high quality forage crops was also desirable for self sufficiency of forage.

In the past few years the use of four fluoroquinolones such as of ofloxacin(OF), norfloxacin(NORE), ciprofloxacin(CIP), enrofloxacin(ENR) in veterinary practice has increased. The aim of this study was to determine the elimination of fluoroquinolones into eggs, by intramuscular injection of laying hens(2.5mg of ENR/kg, 5mg of CIP/kg, 5mg of NOR/kg, 5mg of OF/kg). The treatment of fluoroquinolones was carried out in 3 stages with 9 laying hens (Isabrown), with mean weight 1.8kg, which were housed in individual cages. Four fluoroquinolones were administered to 9 laying hens through intramuscular injection at 1 day, 2 days, 5 days trial respectively. Sample (Albumen, Yolk, Whole egg) were analysed by high performance liquid chromatography (HPLC) with a fluorescence programmable detector and matrix solid phase despersion (MSPD) extraction. Residues of fluoroquinolones were much higher in the yolk than in the albumen. Detectable residues persisted for 12 days, 14 days, 16 days, respectively, in albumen and yolk after the injection was discontinued. The increase of the fluoroquinolones concentration in yolk was very rapid and reached a plateau after 3 days of dosing. In albumen, the fluoroquinolones concentration increased during intramuscular injection. As soon as the injection was discontinued, residues decreased in the albumen and the yolk.

the data which analyze the results of blood cultures are crucial basic information of the empirical therapy for patients with infection since the patterns of the species of microorganism isolated from blood and the results of antibiotics resistance of in-patients as well as out-patients in one hospital in the middle area of South Korea from 2004 to 2006. Blood culture was performed with BacT/Alert 3D(North Carolina, Durham, USA) for 5 days using BacT/Alert SA (Areobic) and BacT/Alert SN (Aneorbic) medium for adult patient and BacT/Alert PF medium for children patients. The antibiotic susceptibility test was performed with VITEK (BioMerieux vitek. Hazelwood. Missori. USA) automated identification as well as susceptibility equipments. Total 39,305 cases of blood culture sample were investigated and positive patients of 2,216 (20.0%) were found. Among those, there were 40 patient with ESBL positive, and blood culture positive smples were 4,798 (12.2%). ESBL positive bacteria were found in 86 samples (including double checked culture bacteria). The majority of ESBL producing bacteria were E. coli, K. pneumoniae and K. oxitoca as ordering based on the number. The research showed the results that there were monre females than male with the bacterias, more E. coli in over 50 years old aged group than other bacterias and largest number of patients with 13 patient (32.5%) in Chungcheongnam – do province were found. he most common ESBL producing bacteria were E. coli throughout 3 years, but K. pneumoniae and K. ocitoca were also fairly found. Interestingly, E. coli was highly found in over 50 years old patients. In conclusion, recovery progress of patients will be badly affected by the high emergence rate of ESBL producing bacteria due to the using of broad spectrum antibiotics. Therefore, significant considering is necessary in the antibiotic use, and continuous infection control and trace observations for all lpatients in hospitals including infected patients are required.

웨이브렛 신경회로망을 이용한 비선형 시스템의 안정한 직접 적응 제어

서재용,연정흠,원경재,서승진,전홍태 중앙대학교 생산공학연구소 1998 생산공학연구소 논문집 Vol.7 No.2

이 논문에서는 웨이브렛 신경회로망을 사용하여 알려지지 않은 비선형 시스템을 안정하게 적응 제어하는 문제를 다룬다. 비선형 시스템의 정확한 제어는 함수를 근사화하는 데 상용된 함수 근사화기의 정확성과 효율성에 의존한다. 이에 기준 함수의 선택이 자유롭고 함수 근사화 능력이 뛰어난 웨이브렛 신경회로망을 비선형 시스템 제어에 사용한다. 초기 웨이브렛 신경회로망 제어기를 설정하는 방법은 먼저 제어기 입력의 시-주파수 특성을 분석해서 웨이브렛 신경회로망 변수인 신축과 이동을 구하고, 다음에 Lyapunov 안정성 이론에 기초한 적응 법칙을 사용하여 연결 강도를 조절하는 것이다. 이 직접 적응 웨이브렛 신경회로망 제어기를 불안정한 비선형 시스템인 역 진자 시스템을 제어하는 데 적용한다. In this paper, we deal with the problem of controlling an unknown nonlinear dynamical system, using wavelet network. Accurate control of the nonlinear systems depends critically on the accuracy and efficiency of the function approximator used to approximate the function. Thus, we use wavelet network which shows high capability of approximating the functions and includes the free-selection of the basis functions for the control of the nonlinear system. The method of constructing an initial adaptive wavelet network controller is that we find the dilation and translation that are wavelet network parameters by analyzing the time-frequency characteristics of the controller's input, and then, the weight is adjusted by the adaptive law based on the Lyapunov stability theory. We apply this direct adaptive wavelet network controller to control the inverted pendulum system which is an unstable system.

본 연구는 교육과학기술부의 경쟁력있는 국립대학을 만들고자 시행하고 있는 여러 정책 중 연합대학으로의 체제 변화 권유에 대한 장단점과 이해득실을 냉철하게 객관적으로 고찰해 보고자 수행되었다. 연구의 수행방법은 연합대학 체제의 추진이나 독자생존의 길 등 의사결정에 참고자료가 될 수 있도록 일본과 미국 등 외국의 연합대학 사례를 중심으로 수집 가능한 자료를 수집하여 고찰한 후 연합대학 체제 추진이나 독자생존의 장단점을 알아보았다. 본 연구의 결과는 여러 가지 외적인 상황 속에서 우리 대학이 독자적으로 생존하는 것이 가능한가, 또는 결국에는 독자적 생존의 대안으로 연합 내지는 통합의 길을 선택할 수밖에 없는가 하는 것은 그 누구도 쉽게 예단하기 어렵다는 것이다. 그러나 대학 구성원들이 미래를 선택하지 않는다 하더라도 외적인 요인에 의해 미래가 결정될 여지가 있으므로 지금부터라도 대학의 미래에 관한 공동의 지혜를 모아야 할 것으로 생각한다. 함께 머리를 맞대고 허심탄회하게 서로의 의견을 존중하며 서로에 대한 불신을 털어버리고 진정 대학의 미래를 위한 바른 선택이 무엇인가에 관한 논의와 연구가 꾸준하게 지속되어야 할 것으로 판단된다. This study was carried out in order to try to consider objectively merits and demerits regarding a system change invitation toward the Union University System and understanding gains and losses during a lot of policies to make a national college that there was competitiveness of Ministry of Education, Science and Technology of education. The results of this study is that no one is easy to predict, that it does as alternatives of an independent survival or select a street of integration and the Union University System in various external situations, finally. However, the University members does not select the future even if in various external factor because there is no doubt that the future will be decided from now on any University in the future regarding collaborative wisdom of the university, We thought it was going to do. Head with open-minded to respect each other's opinions and distrust each other confide you discard the truly University for the future, select the right to discuss and research can be sustained.

오주원,서재민,안승근,박주미,강철균,송광엽 대한치과보철학회 2012 대한치과보철학회지 Vol.50 No.2

연구 목적: 본 연구는 탄성의치 제작 시 주로 사용되는 polyamide를 수종의 연마방법을 사용하여 처리 후 Candida albicans의 부착정도와 표면거칠기를 비교하고자 하였다. 연구 재료 및 방법: 25×15×2 mm 크기의 polyamide 시편을 4군으로 나누어 연마재를 사용하여 기공용 lathe 연마하는 방법(기공실내 연마방법)과 각기 다른 2종의 실리콘 포인트로 진료실내 연마하는 방법, 그리고 실리콘포인트 연마 후 pumice로 연마하는 방법으로 처리하였다. C. albicans의 부착성을 평가하기 위해 5×106 CFU/ml의 C. albicans 현탁액에 시편을 2시간 동안 침적하였고 5회 수세처리 후 한천배지에서 배양하였다. 그리고 주사전자 현미경(JSM-5900, JEOL LTd., Tokyo, Japan) 촬영을 시행하였다. Profilometer (Surf-pak; Kawasaki, Japan)를 이용하여 표면거칠기를 측정하였고 통계처리를 위하여 SPSS 18.0 프로그램을 사용하였다. 일원변량분석으로 비교 분석하였고 사후검증은 C. albicans의 부착성 검증을 위해 Scheffe test를 시행하였으며 표면조도검증을 위해 Tamhane’s T2 test를 시행하였다(α=.01). 결과: 최대 거칠기 값을 보인 군은 2단계의 연마용 버를 사용한 것으로 0.32 ㎛±0.10 값을 나타냈으며, 가장 낮은 거칠기 값을 보인 것은 tungsten carbide를 사용하지 않고 기공용 lathe로만 연마를 한 군으로 0.02 ㎛±0.00의 거칠기 값을 나타냈다. C. albicans 부착 실험에서는 기공용 lathe만을 이용한 연마방법이 가장 적은 부착수를 보였으며 다른 세 군과 유의한 차이가 발견되었다(P<.01). 결론: 표면거칠기 및 미생물 부착능 실험 결과 기공실 연마만을 시행한 경우 유의하게 낮은 거칠기 값과 부착율을 보였다. Pumice로 추가 연마한 군은 진료실연마를 시행한 군에 비해 낮은 거칠기 값을 보였으나 C. albicans 부착에 있어서는 유의한 차이를 보이지 않았다(P>.01). Purpose: The purpose of this study was to compare the effect of 3 chairside polishing methods and laboratory polishing methods on surface roughness and C. albicans adhesion of polyamide denture base. Materials and methods: Using contact profilometer, the surface of polyamide specimens (25×15×2 mm) was studied after conventional polishing without finishing and after chiarside polishing with 2 chiarside polishing kits and chairside-pumice polishing following finishing with tungsten carbide bur. To evaluate the adhesion of C. albicans, C. albicans suspension was overlayed on the test specimen. And the specimens were incubated for 2 hours. Imprint culture method was achieved and counted the colony on the agar plate. Polished polyamide were evaluated using a scanning electron microscope. The statistics were conducted using one-way ANOVA and in case of difference, Scheffe test and Tamhane’s T2 test were used. Results: Surface roughness (Ra) of surfaces polished with 2 chairside polishing kits had higher than conventional polishing and pumice polishing. The highest roughness value was 0.32 ± 0.10 ㎛, and the lowest was 0.02 ± 0.00 ㎛. The adhesion of C. albicans on the specimens polished with chairside polishing group and pumice polishing group were increased than conventional polishing group (P<.01). Conclusion: Conventional laboratory polishing was found to produce the smoothest surface and the lowest adhesion of C. albicans. Two groups polished with Chairside polishing kits were similar with respect to surface roughness. Surface of the specimen polished with pumice is significantly smoother than 2 chairside polishing groups, but the result of C. albicans adhesion is that group polished with pumice was similar with 2 chairside polishing groups (P>.01).
