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.

Objectives : In order to investigate the efficacy and safety of the newly developed herbal medicine Jetongdan, a placebo-controlled randomized clinical trial of patients with osteoarthriotis of the knee was undertaken. Methods : Data were obtained from 80 patients with OA of the knee. After the enrollment, they were asked to answer a disease-specific questionnaire (Western Ontario and McMaster Universities (WOMAC) OA index) and analyzed with the erythrocyte sedimentation rate (ESR) in order to evaluate the efficacy of Jetongdan, and analyzed for aspartate transaminase (AST) level, alanine transminase (ALT) level, blood urea mitrogen (BUN) level, and creatinine (Cr) level in order to evaluate the safety of Jetongdan. Results : The liver function and renal function did not deteriorate after treatment with Jetongdan. Composite WOMAC score and physical function subscale was improved, but pain subscale, stiffness subscale, and ESR were not improved by Jetongdan. This was possibly because the baseline characteristics of the two groups were not homogenized after randomization. Conclusions : Jetongdan could be a promising treatment option for osteoarthritis of the knee. Further study in a larger population with appropriate severity grades is recommended.

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 primary medical care is the most important part in the Medical Delivery System. So this study was to survey the average of treatment amount among the kind of specialty through the medical insurance claims concerning 963 clinics during the period of one year, 1997, in Taegu. The average revenue of medical treatment amount was 187,950,000won, the average case of medical treatment amount was 9,255cases and the charges per case was 21,596won. The result of survey about the internists, general surgeons, family physicians, general practitioners and pediatricians was as follows : Upon the treatment cases, significant variables of the internists were the number of practitioners of clinic, employed numbers and the number of equipments. Significant variables of the general surgeons were the age of practitioners, the opening year, the number of practitioners, employed numbers and the number of beds. Significant variables of the family physicians were the age of practitioners, the opening year and the number of equipments. Significant variables of the general practitioners were the number of practitioners of clinic and number of beds. Significant variables of pediatricians were the number of practitioners and employed numbers. In view of the tendency for the park of medical insurance to enlarge more and more in revenue of the whole treatment amount, and through the analysis of factors influencing upon treatment amount of medical insurance, we will anticipate the expenditure of treatment amount of insurance and need to establish efficient medical insurance policy to reduce the differences between the distributions of treatment amount of insurance among special departments. Therefore the health manpower policy about the private medical practitioners will be continuously study.

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).

나도향 소설에 나타나는 열정의 의미 연구

서재원 현대문학이론학회 2003 現代文學理論硏究 Vol.0 No.19

The main stream of this analysis is focused on the meaning of 'Passion' going through his novels. "The period of young ages" is well represented by the reflection of inner feeling. The overflow of passion is intentionally selected by the novelist. Both "A woman hairdresser" and "A diary of train conductor" are well articulated a chasm between internal passion and external reality. His good observation could contribute to discover the distinction among two themes. "A water mill" and "Bbong" might be chosen as a masterpiece of his works based on the way of articulation deriving from 'passion'. The reason is why that these two novels are clearly different from his previous type of novels. The biggest difference is smoothly melted down two key subjects of inner passion and external reality. But it is also existed some different views across them. The heroine of "A water mill" is always battled with irrevocable reality so that death is inevitable conclusion. In contrast, the heroine of "Bbong" is trying to shake hands with restrained realty. His outstanding contribution in modern korean novels is that he successfully introduced and created the person who has strong 'passion' as a hero distinguished by rational human being as different as previous novels.

Objectives : to evaluate the effects of Jetongdan, the newly developed herbal medicine, on the quality of life in patients with osteoarthritis of knee Methods : Placebo-controlled, randomized clinical trial on the 80 patients with osteoarthritis of the knee was fulfilled. After enrollment, they took medication as they enrolled. And they were asked to answer the questionnaires (Korean Health Assessment Questionnaire (KHAQ), Lequesne's functional index (LF1), visual analogue scale (VAS)) and analysed with the erythrocyte sedimentation rate (ESR) at baseline, after 4 weeks and 8 weeks of medication. Results : Total KHAQ score, some categories of KHAQ like hygiene, activities were significantly improved after 8 weeks of medication. And the change of the KHAQ score was significantly correlated with the change of VAS. But LFI, VAS, ESR level was not significantly improved, and it was considered because of the short medication period and small size of study population. Conclusion : In conclusion, Jetongdan could improve the health-related quality of life in patients with osteoarthritis of knee. Further study in the large population, in long period were recommended.
