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.

A multi-residue matrix solid-phase dispersion extraction and the liquid chromatographic determination of enrofloxacin, ciprofloxacin, norfloxacin and ofloxacin in eggs is described. Blank and fluoroquinolones fortified egg samples (0.5 g) containing oxalic acid 0.05 g and sodium sulfate (anhydrose) 0.5 g were blended with octadecylsilyl (C_(18), 40 m, 18% load, endcapped, 2 g) derived from silica. After homogenization, C_(18)/egg matrix was transferred to column made of 10 ml plastic syringe and filter paper, and compressed 4.0 4.5 ml volume. A column was washed with 8 ml of hexane followed by 8 ml of ethylacetate and dried under N2 gas. Fluoroquinolones were eluated with 8 ml of methanol under gravity. The eluate contained fluoroquinolones, was free from interferences when analyzed by high performance liquid chromatography with fluorescence detection. Correlation coefficients for the fluoroquinolones standard curves (linear regression analysis, n = 5) ranged from 0.99918 (± 0.0035) to 0.99985 (± 0.0002). Aveage recoveries of fortified samples were between 89.4 and 103.5%. The method comparared favorably with the classical method in terms of the sample size, analysis time and overalls costs.

This study was to survey for provide to institutional method about publicity of smoking dangerousness by 210 students of a college in Daegu city. As the result of this study, the gender smoking were significant difference between men(55%) and women(13%). A large majority(77%) in smoking group wanted to education of quit smoking. And starting age of smoking were a middle school(34%), a college(33%), a high school(25%), an elementary school(8%). Smoking amount per a day were less than a half(49%), less than a pack(35%), over than a pack(16%). The reason of continuous smoking were habituation(66%), to slove the stress(17%), to look smart(9%). So it is necessary to early education for quit smoking from elementary school. And a systematic program for college students must be established to solution the smoking at the government authorities, official quarters of school and citizens' groups, etc.

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.

The mass treatment trial of pyrantel pamoate on Ascaris lumbricoides and Ancylostoma duodenale infections was carried out to school-children and inhabitants in rural areas in the central part of Korea. Pyrantel pamoate ("Combantrin") tablet (123 mg base) was administered as a single dose of 10. 0 mg per kg. body weight to a total of 4,198 Ascaris infected cases selected out of 4,436 (41. 6%) positives, who were screened from the total 10,660 collected stool specimens. Of these, only 3,169. cases were followed up after treatment to provide an analysis in this study. Incidentally 161 cases with concomittently infected hookworm were also subjected to assess the efficacy of pyrantel pamoate against A. duodenale. The egg negative conversion rate on A. lumbricoides was 95.3%, and on A. duodenale, 97.5% four weeks following treatment. In failed cases, the egg reduction rates on both of the infections were 97.6% and 97.3% respectively. No side effects and no problem in drug administration were demonstrated. It is concluded that this study confirms the high efficacy of pyrantel pamoate in the treatment of Ascaris lumbricoides and Ancylostoma duodenale infections and also proves the acceptability and safety of this drug in the mass treatment of ascariasis in a population with relatively high worm burden.

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.

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.

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.
