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.

The introduction of muscle relaxants was an epoch making event in the development of clinical anesthesia and their use has hecame essential to anesthesia practice. Vecuronium, one of the newest muscle relaxants, many advantages; it is .apid acting, non-accumulating, has minimals side reactions and is promptly antagonized by anticholinesterases. However, its pharmacological effect, like other conventional muscle relaxants depends upon the dose and is influenced br many factors including body temperature, blood flow, interaction with other drugs, antibiotics, diuretics and so forth, To obtain a dose·response relationship which is important for clinical use, the effect of the vecuronium in various doses on the neuromuscular block in rabbits was investigated. The results were as follows. 1) In the vecuronium 0.025 mg/kg group, maximal twitch depression was varied between 75 to 92% with a mean value of 84,9%. The spontaneous recovery index was 141.0 seconds (2.35 min). 2) In the vecuranium 7.75 mg/kg group, thmean maximum twitch depression and spontaneous recovery index were 98.4% and 218.6 seconds (3.64 min.) respectively. 3) In the vecuronium 7.1 mg/kg group, maximum twitch depression was 100% and the spontaneous recovery index was markedly prolonged to 627.8 seconds (10.35 min).

본 연구는 부존 조사료자원 이용으로 수입사료를 줄이고 사료비를 절감하고자 2010년도에 전남 해남(간척지), 강원 평창(강변), 원주(섬강변), 전남 영광(와탄강변) 등 4개 지역에서 갈대와 억새 등 야초 자생지를 탐색하고, 수확·이용실태 조사와 함께 사료가치를 분석하였다. 전남 해남 해남목장 내 갈대(Phragmites communis) 위주의 야초 자생지는 300 ha로 예년에는 2회 곤포작업하여 연간 사일리지로 2,300~2,500톤(ha당 8톤)을 생산하였으나 2010년도는 1회 곤포조제로 사일리지 2,000톤(ha당 7톤)을 생산하였다. 유통가격은 롤 당 53천원으로 ㎏당 110원이었다. 곤포는 전량 자가소비하며, 외부 작업단에 롤 당 26천원의 작업비를 지불하였다. 연간 조수입은 2억 2,260만원이며, 소득은 1억원 수준(345천원/ha)이었다. 초장 150 ㎝의 갈대는 조단백질 8.4%, 상대사료가치 71.9 (건초 5등급), 건물 소화율 60.1%로 사료가치는 볏짚에 비해 약간 나은 것으로 평가되었다. 갈대 사일리지의 사료가치와 유기산 함량은 동일 지역에서 동일한 재료로 사일리지를 조제하더라도 수확시기에 따라 차이가 컸으며(CP 4.7~6.4%, RFV 62.2~78.9, 건물 소화율 41.9~53.9%), 갈대 사일리지의 품질은 수단그라스에 비해 불량하였다. 강원 평창 강변 자생갈대의 사료가치는 초장이 79, 117, 121, 142㎝로 생육이 진행됨에 따라 낮아져, 조단백질은 각각 13.9%에서 7.6%로, 상대사료가치는 90.7 (건초 3등급)에서 76.1 (건초 4등급)로, 건물 소화율은 72.9%에서 54.7%로 감소하였다. 원주 섬강 주변 야초류는 곤포수확 작업에 어려움이 있었으며, 초장 130 cm의 갈대는 조단백질 8.5%, 상대사료가치 82.3 (건초 4등급), 건물 소화율 70.2%로 사료가치는 높았으며, 220㎝의 성숙한 갈대는 조단백질 10.2%, 상대사료가치 65.1 (건초 5등급), 건물 소화율 48.9%로 볏짚 대비 조금 나은 것으로 평가되었다. 전남영광지역에서는 와탄천 주변에 자생하는 갈대를 수거 이용하고자 시도하였으나 경제성이 없어 중단하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거·이용하되, 사료가치를 유지하고 가축 기호성이 양호한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전(늦어도 7월까지)에 수확·이용하는 것이 권장된다. This study was carried out in 2010 to investigate the utilization and forage quality of native grasses, such as Phragmites communis which might reduce the cost of feeding domestic cattle. The regions surveyed were the Haenam ranch in Haenam, Pyeongchang, Wonju, and Yeonggwang. In Haenam, yearly silage production harvested from 300 ha was 2,000 MT (7 MT/ha). All of those round bale silages were self-consumed in that region, and marketing price was 50,000 55,000 won per roll (110 won/㎏). Phragmites communis of 150 ㎝ in length contained 8.4% crude protein (CP) with relative feed value (RFV) 71.9 and 60.1% in vitro dry matter digestibility (IVDMD), which was somewhat more favorable than forage quality of rice straw. The silage quality of Phragmites communis varied greatly by the time of harvest (CP 4.7 6.4%, RFV 62.2 78.9, and IVDMD 41.9 53.9%), even with the same district and of the same original forage materials. Generally, the quality of Phragmites communis silage of was poorer than that of sorghum * sudangrass hybrid. In Pyeongchang, forage quality of Phragmites communis was decreased from 13.9% to 7.6% in CP, 90.7 to 76.1 in RFV, and 72.9% to 54.7% in IVDMD, as plant was getting mature, from 79 ㎝ to 117 ㎝, 121 ㎝ or to 142 ㎝ in length. In Wonju, the quality values of Phragmites communis of 130 ㎝ in length were 8.5% CP, 82.3 RFV and 70.2% IVDMD, while those of matured grasses of 220 ㎝ in length were lower (10.2% CP, 65.1 RFV and 48.9% IVDMD), but this was a little more favorable than quality of rice straw. In Yeonggwang, feeding Phragmites communis was tried in a Hanwoo feed, but stopped due to low profitability. In conclusion, the overall quality of most native grasses including Phragmites communis in this survey was poor. Therefore, we recommend that Phragmites communis and native grasses should be harvested on June or July to obtain richer forage quality in forage values than rice straw.

본 연구에서는 감귤 과피 가공부산물로부터 기능성 polyphenol 및 flavonoid가 새로운 추출방법인 아임계 추출법을 통해 추출되었고, 열수(80oC), 에탄올, 설탕용액을 이용한 기존 추출법과의 추출효율이 비교 분석되었다. 건조된 감귤 과피로부터 총 polyphenol(27.25±1.33mg QE/g DCP) 및 flavonoid(7.31±0.41mg QE/g DCP)에 대한 최대수율이 아임계 추출법(190°C, 1300 psi, 10 min)을 통해 획득되었으며, 이것은 기존 추출법 가운데 가장 높은 수율을 보인 에탄올 추출법을 통한 총 polyphenol(3.79±0.73mg QE/g DCP) 및 flavonoid(0.86±0.27mg QE/g DCP) 수율 대비 7.2배와 8.5배 이상 더 높은 것이었다. 추출방법에 따른 감귤 과피 추출물의 항산화 활성은 큰 차이를 나타내지 않았으나, 이러한 결과는 건조 감귤 과피 1g 당 아임계 추출법(190oC, 1300 psi, 10 min)에 의한 항산화 성분의 상대 수율(relative yield, %)이 다른 추출방법을 통해 획득된 것보다 대략 9.5배 이상 더 높다는 것을 설명하는 결과로, 아임계 추출법이 기존의 전통적 추출법에 비하여 감귤 과피의 기능성 polyphenol 및 flavonoid를 추출하는데 매우 적합한 방법임을 제시하고 있다. The extraction of polyphenol and flavonoid from citrus peel was performed by the ethanol, sugar, hot water (80oC), and subcritical water extraction methods. The maximum yields of total polyphenolic compounds (27.25±1.33mg QE/g DCP, QE and DCP indicate quercetin equivalent and dried citrus peel, respectively) and flavonoids (7.31±0.41mg QE/g DCP) were obtained by subcritical water extraction (SWE) with operating conditions of 190oC, 1300 psi, and 10 min. The yields by SWE were over 7.2-, and 8.5-fold higher than those of total polyphenols (3.79±0.73mg QE/g DCP) and flavonoids (0.86±0.27mg QE/g DCP) obtained using the ethanol extraction, which showed the highest extraction efficiency among tested conventional methods, respectively. Antioxidant activities of extracts obtained by different methods showed no significant differences. However, the relative antioxidant yield per 1 g dried citrus peel by SWE (190oC, 10 min) was over 9.5-fold higher than that by the ethanol extraction.

In this study, Fe₃O₄-ACCS-Ag nanoparticles (NPs) were successfully synthesized using silica extracted from corn cob ash. The synthesized Fe₃O₄-ACCS-Ag NPs were characterized using X-ray diffraction (XRD), scanning electron microscopyenergy dispersive X-ray spectroscopy (SEM-EDX), transmission electron microscopy (TEM) and fourier transform infrared spectroscopy (FTIR). In addition, the potential application of Fe₃O₄-ACCS-Ag NPs as an antibacterial material in water disinfection was investigated using Escherichia coli ATCC 8739 as model bacteria. The antibacterial activity of synthesized composite material showed 99.9% antibacterial effect within 20 min for the tested bacteria. From this experiment, the synthesized Fe₃O₄-ACCS-Ag nanocomposites also hold magnetic properties and could be easily recovered from the water solution for its reuse. The reused nanocomposites presented the decreasing antibacterial efficiencies with the reuse cycle but the composite used three times still killed 90% of bacteria in 20 min.

Objectives : Since the publication of Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) in 2002, there has been a substantial need for a revision due to rapid progress in the pharmacological management for depressive disorder. We revised KMAP-MD to Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. This paper is one of the following 4 papers consisting of Korean pharmacological algorithm for depressive disorder. Methods : The questionnaire consisted of 4 parts ; initial treatment of 1) non-psychotic depressive disorder, 2) psychotic depressive disorder, 3) treatment strategy for clinical subtypes and drug choice considering adverse effects, and 4) treatment for depressive disorder in women. It was composed of 22 questions, and each question had 54 sub-items. The questionnaire was completed by the review committee consisting of 101 experienced Korean psychiatrists. We classified the expert opinion to 3 categories (the first-line, the second-line, or the third-line). Results : For non-psychotic major depression, regardless ofthe severity of an episode, the antidepressant (AD) monotherapy was the optimal first-line treatment. SSRI, venlafaxine, and mirtazapine were the 1st-line AD. In case of a partial or no response to initial strategy, adding another AD was recommended. For psychotic major depression, combination of an AD and an atypical antipsychotic (AAP) was the treatment of choice. Among AAPs, quetiapine, rispendone, olanzapine were preferred. For non-responder to initial strategy, the next step was adding or changing AD before changing AAP. For women with premenstrual dysphoric syndrome or postpartum depression without psychotic features, AD monotherapty was a preferred strategy while for psychotic postpartum depression, combination of AD and AAP was recommended. Experts recommended various ADs according to adverse effect. Conclusion : These results suggest that the medication strategies for depressive disorder are rapidly changing and reflect the recent studies and clinical experiences.

본 연구에서는 부산광역시에 소재한 초,중,고등학교 72개교와 체육공원 9개소의 체육시설을 대상으로 현장을 직접 방문하여 안전도 측면에서 체육시설의 상태를 양호, 보통, 불량으로 나누어 20명의 조사자가 객관적인 관점에서 체육시설을 항목별로 구분한 것을 토대로 평가 하였고 또한 체육시설에 대한 실측이 필요로 하는 것은 정확한 측정을 하여 문제점을 분석하였다. 그 결과 학교체육시설은 시설의 설치와 관리상태 그리고 정비에 대한 관심이 안전도 측면에서 학생들이나 일반인들이 이용할 때 최적의 체육시설을 이용할 수 있도록 학교와 교사 그리고 행정기관에서 적극적인 재정지원과 관심이 요구되었고 체육공원시설은 질적인 면만이 아니라 양적으로도 고려가 되어야 하고 무엇보다도 수요자 중심으로 다양한 연령층을 고려하여 사회체육의 저변확대에 기여할 수 있을 것으로 본다. 체육공원시설은 누구나 쉽게 접할 수 있는 배치와 설계가 이루어짐으로서 지역사회의 주민이 체육활동을 할 수 있는 기회를 쉽게 제공하여야 할 것이다. 또한 기존의 공원체육 시설이 안전도 측면에서 양호한 수준으로 되기까지는 행정기관의 적극적인 관심과 경제적인 지원이 지속적으로 이루어져야 할 것으로 본다. 결론적으로 체육시설은 안전도를 고려하여 설계되고 배치되어야 한다. 또한 누구나 안전하게 이용할 수 있도록 고려되어짐으로서 운동으로 인한 안전사고를 최대한 예방할 수 있을 것으로 본다. This study investigates and examines exercise facilities of 72 elementary and secondary school and 9 athletic parks all over the city of Pusan, and estimates their human-engineering aspects according to researcher's subjective standards(low, mid, and high level). It also finds out and analyzes items which needs measurement and estimation in exercise facilities, and concludes as follows: 1) In the case of exercise facilities in schools, more active attention must be given to their erection and control, and their constant checking and repair. Safety accident must also be prevented by providing optimal exercise facilities made in human-engineering way with students and ordinary people using them. Therefore, both school administrator and teachers must pay much mort attention to exercise facilities on schools and more much money must be invested for them. 2) In the case of exercise facilities of athletic parks, their quantity as well as qu must be emphasized, and, above all, safe user-centered exercise facilities must be designed and manufactured on the basis of the safety, and be provided with the people of different ages.

서정원,윤민혁,강원구,권광일 충남대학교 약학대학 의약품개발연구소 2007 藥學論文集 Vol.22 No.-

The aim of this study were to confirm the analysis method and also to estimate the pharmacokinetic parameters of amlodipine in human volunteers. In an open-label single-dose pharmacokinetic study, a group, consisting of 24 healthy volunteers, received single oral dose of 5mg amlodipine. Blood sample were taken for up to 120 hours. The concentration of amlodipine in these body fluids was determinated using a validated high-performance liquid chromatography(HPLC) method with tandem mass spectrometry. Amlodipine and ketoconazole, an internal standard, were extracted from plasma using ethyl acetate in the presence of 0.1M sodium carbonate. After drying the organic layer, the residue was reconstituted in mobile phase(acetonitrile : water = 70 : 30 v/v (0.1% formic acid)) and injected onto a Zorvax C18 column (2.1 × 100 mm, 3.5 ㎛ particles). The isocratic mobile phase was eluted at 0.2ml/min. The ion transitions monitored in multiple reaction-monitoring mode were m/z 410.10 → 294.95 and 532.11 → 81.95, respectively. The coefficient of variance of the assay precision was less than 12%, and the accuracy exceeded 99.1%. The limit of quantification was 0.1 ng/ml. The pharmacokinetic parameters were calculated with non-compartmental(AUC, C_(max), T_(max), CL_(t), V/F) and compartmental(K_(el), K_(a), t_(lag)) pharmacokinetic analysis using WinNonlin program. The estimated means of AUC_(0-120hr), C_(max) and T_(max) were 196.90 ± 5.02 ng·hr/ml, 3.36 ± 0.09 ng/ml and 10.44 ± 0.61 hr, respectively. The means of other pharmacokinetic parameters(V/F, CL_(t), K_(el), K_(a) and t_(lag)) were 1208.06 ± 50.61 L, 25.39 ± 0.65 L/hr, 0.2806 ± 0.0294 hr^(-1), 0.0210 ± 0.0008 hr-1 and 0.4574 ± 0.0635 hours, respectively.
