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.

서성(Sung Seo),한대덕(Dae Duk Han),장선식(Sun Sik Jang),김원호(Won Ho Kim),정민웅(Min Woong Jung),최진혁(Jin Hyuck Choi),김진숙(Jin Sook Kim),김하영(Ha Young Kim),이종경(Joung Kyong Lee) 한국초지조사료학회 2012 한국초지조사료학회지 Vol.32 No.1

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.

김석홍,주경웅,최원기 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1996 Journal of biomedical laboratory sciences Vol.2 No.2

토끼 출혈증 바이러스에 감염된 조직을 10% 포르말린 고정, 파라핀 블록으로 보관했던 것으로 표본을 만들고 biotin 표지된 올리고뉴클레오티드 probe를 사용하는 in situ hybridization 기법으로 viral RNA를 조사하였다. in situ hybridization 기법은 핵산을 규명하는 다른 방법들에 비하여 신속하고 특이성이 높은 기법으로 모든 과정이 Microtrobe(Tm) capillary action system에서 1-2시간 이내에 완료된다. Viral RNA는 간세포의 세포질과 신장의 피질에서 주로 관찰되었으나, 폐조직과 신장의 수질에서는 부분적으로 적색신호가 보였다. 비록 기술적인 한계를 가지고 있지만 다른 핵산 진단방법 보다 많은 장점을 가지고 있어 조직 병리학적으로 바이러스 진단하는데 하나의 독특한 기법으로 채용되리라 기대된다. In this paper, a in situ hybridization(ISH) has been used to investigate the yield of viral RNA expression from each organ tissues. It is studied to establish a rapidly, specific diagnostic method detecting rabbit haemorrhagic disease virus(RHDV) RNA in 10% formalin-fixed, paraffin-embedded tissues of naturally RHDV-infected rabbits using oligonucleotide probe to be made by RHDV total sequences. Biotin was used as the oligonucleotide probe marker. In situ hybridization is detected the virus genome in the cells and tissue as specifically compared with others nucleic acid hybridization method. All ISH procedure of RHDV were completed to Microbrobe(Tm) capillary action system within 1-2 hours. In this report, RHDV was distributed widely in the cytoplasm of liver cell and the cortex of kidney but lung tissue and medulla of kidney were showed to positive reaction at locally. Although not entirely free of technical limitations, nucleic acid identification holds advantages over other diagnostic tests, including exquisite sensitivity, specificity, interchangeability and speed. It is expected that, in the immediate future viral nucleic acid detection will be a prominent part of the methods used in histopathology.

김창원,최웅재,우병훈 한국학교체육학회 2002 한국학교 체육학회지 Vol.12 No.2

본 연구의 목적은 8번 아이언으로 30M 거리를 칩 샷을 통한 3차원적 운동학적 분석을 통해서 칩 샷의 원리와 근거를 제시하여 골퍼들의 기초 자료를 제공하고자 하는데 그 목적을 두었다. 1. 선운동의 변인 스윙 소요시간에서는 숙련자가 1.083±0202sec.로 비숙련자는 1.217sec. 유의한 차이를 보였다(p<.05). event별로는 event 1에서만 유의하게 숙련자가 빠르게 나타났지만(p<.05), event 2,3에서는 차이를 보이지 않았다. 클럽헤드 속도에서는 event 3(p<.001), 4(p<.01)에서 비숙련자가 숙련자보다 빠르게 나타나 통계적으로 유의한 차이를 보였지만, event 1, 2에서는 차이를 보이지 않았다. 신체중심변위에서는 event 3에서만 숙련자가 비숙련자보다 중심이 낮게 형성되었고(p<.05). 나머지는 event 1, 2, 4에서는 차이를 보이지 않았다. 2. 관절운동의 변인 코킹각 변위에서는 event 2(p<.05), 3(p<.01)애소 통계적으로 유의한 차이를 보였고, event 1, 4에서는 차이를 보이지 않았다. 양 슬관절 각 변위에서는 오른쪽 슬관절의 event 1을 제외하고는 통계적으로 유의한 차이가 없었다. 고관절의 각 변위에서는 집단간의 통계적으로 유의한 차이가 없었다. This study is designed to present the principles and foundation of chip shots through a chip-shot three-dimension kinematic analysis of 30-meter distance with the 8th iron and to offer the reader basic materials for golfers. 1. The variations of Lineal Exercise There is a significant difference between the time required for a swing by skillful golfers(1.083±0.02sec.) and the time required for a swing by unskillful golfers(1.217sec.). Although event 1 shows that the former turns out to be faster(p<.05), event 1 and even 2 show no difference. In terms of the velocities of the clubhead, event 3(p<.001) and event 4(p<.01) turn out for the latter to be faster than the former, which means that there is a significant difference. But there is no difference in event 1 and 2. In terms of the displacement of the body center, the former forms the body center lower(p<.05) than the latter in event 3, while there is no difference in event 1, 2, and 4. 2. The Variations of the Joint Exercise In terms of the displacement of the left wrist, event 2(p<.05) and event 3(p<.01) show a statistically significant difference, and event 1 and event 4 show no difference. In terms of each displacement of both the knee joints, event 1 of right knee joint only shows statistically significant difference. In terms of each displacement of the coxal articulations, there is no statistically significant difference between groups.

This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc.) were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

This study was carried out to investigate psychiatric stress symptoms and stress- inducing factors, such as role overload, work demand, work procedure and so forth in korean dental laboratory technicians. Questionnaires were mailed to randomly selected 1000 dental technicians who were systematically selected. Among them, 786 dental technicians completed the questionnaires and returned them. Validity test and reliability test on the questionnaires were done prior to the main survey, using the SCL-90-R as a standard. Stress-inducing factors were identified with a multiple regression analysis on the continuous variables. To investigate stress-inducing factors on stress symptoms, analysis on distribution of characteristics was performed, and then correlation analysis and multiple regression analysis was carried out. The results of the study were as follows: According to multiple regression analysis, there was a statistical correlation between stress symptoms and role overload, work procedure, occupation conflict, interpersonal relationship, social support, personality traits in stress symptom(GSID). The stress symptoms in korean dental laboratory technicians seemed to be mostly job related ones, and considering the results obtained from the study, it is suggested that reducing work load and proper health promotion programs for dental technicians be necessary.

Clopidogrel bisulfate, a widely used inhibitor of platelet aggregation, is considered at least as safe as aspirin. We describe a 61 year old male patient who developed a systemic inflammatory response syndrome consisting of high fever, rash, chills, impaired liver function, and mild leukopenia after receiving clopidogrel after coronary angiography and stent implantation. The reaction resolved promptly after withdrawal of the drug, thus making the diagnosis of a clopidogrel induced reaction highly probable.
