강희신,John R. Ashes 한국낙농학회 1985 韓國酪農學會誌 Vol.7 No.2

三年餘 貯藏되었던 Alfalfa 葉 粉末에 ^(14)C-HCHO를 其 合有 蛋白質의 0, 0.5, 1.0 및 2.0% 水準으로 處理하였을 때의 in vitro 減成化度를 測定하였는 바 다음과 같은 結果를 얻었다. (1) In vitro 蛋白質 減成化度는 12.7∼1.1%의 範圍에 있었으며 HCHO處理 水準 0, 0.5, 1.0, 및 2.0% 水準에 따라 각각 12.7, 12.0, 7.9 및 1.1%의 減成化度를 나타내었다. (2) HCHO의 處理는 醱酵 Tube內 溶液中의 揮發性 脂肪酸 濃度에 影響을 미치지 않았다. (3) ^(14)C-HCHO의 回收率은 平均 72.3%로서 基質의 蛋白質과 HCHO가 잘 結合되고 있음을 알게 되었다. In order to test the efficacy of HCHO treatment on alfalfa leaf meal for protecting its protein from degradation in in vitro fermentation, aged alfalfa leaf meal for about three years was treated by ^(14)C-HCHO at the level of 0, 0.5, 1.0 and 2.0% of protein content of the raw material and the protein degradability was measured with the amount of NH₄-N (㎎) over the total nitrogen presented per test tube after 24 hours incubation by using and incoculum collected from the sheep fed alfalfa pellet. The results obtained were summarized as follows; 1. The protein degradabilities measured were 12.7, 12.0, 7.9 and 1.1% for the ^(14)C-HCHO levels of 0, 0.5, 1.0 and 2,0% respectively. 2. No differences between treatments were found in the VFA concentration of the fermentation fluids in the tubes. 3. The recovery rates of protein bound formaldehyde from the treated alfalfa leaf meals were averaged 72.3%.

低質 粗飼科 밀짚으로 飼育되는 交雜種 緬羊 6頭를 供試하며 alfalfa 葉 粉末, 當年葉, 貯藏葉, 2% HCHO處理 當年葉 및 4% HCHO處理貯藏葉을 供試 飼料로 하고 밀짚 基本飼料 700g 및 alfalfa 粉末 補充飼料 300g 計 1.0㎏를 日量 飼料로 連續 給餌器에서 3시간 間隔으로 1日 8回 給與하며 20日間씩의 代謝試驗을 4回 實施하였다. ^(51)Cr-EDTA 및 ^(103)Ru-phe의 二重 標識物質을 使用하여 腸內 內容物의 通過量 및 滯在時間反芻胃 溶量, 有機物 및 窒素의 利用性을 測定한 結果 다음과 같은 結果를 얻었다. 1. 反芻胃 溶液中의 NH₃態 窒素 濃度는 貯藏葉이 當年葉보다 17.5% 높으며(P<.01) 2% HCHO處理 當年葉은 그 無處理보다 7% 程度 減少되고 4% HCHO處理 貯藏葉은 無處理보다 34.0% 程度 減少(P<.01)되었다. 2. 反芻胃로부터 流入되는 NH₃態 窒素 量은 當年葉보다 貯藏葉이 18% 增加(P<.01)되고 2% HCHO處理 當年葉은 無處理보다 6% 減少 (P<.05)되며, 4% HCHO處理 貯藏葉은 無處理보다 32% 減少(P<.01)를 나타내었다. 3. 第4胃內 NAN含量은 當年葉이 貯藏葉보다 6% 增加되며 2% HCHO處理 當年葉은 無處理보다 5.6%의 增加(P<.05) 4% HCHO處理 貯藏葉은 그 無處理보다 17% 程度의 增加(P<.01)를 나타내었다. 4. 第4胃로부터 排出되어 小腸에 流入되는 NAN의 量은 當年葉보다 貯藏葉이 9.0% 더 流入되며(P<.05) 2% HCHO 處理 當年葉은 그 無處理보다 6% 程度 增加(P<.05) 流人되었다. 5. 飼料源 室素 100g 攝取量當 NAN의 小腸內 消化量은 當年葉보다 貯藏葉이 10% 程度 消化가 增進(P<.05)되며 2% HCHO 處理 當年葉은 無處理보다 6% 程度 消化가 增進(P<.05)되었다. 6. 飼料源 室素 100g 攝取量 當 糞中 窒素의 排泄量은 當年葉보다 貯藏葉이 8% 정도(P<.01), 2% HCHO處理 當年葉은 無處理보다 6% 程度(P<.05) 더 排泄되었으며 4% HCHO處理葉은 그 無處理에 比하여 2% 程度 더 排泄되었으나 有意差는 認定되지 않았다. 7. 反芻胃液(Y, ㎎ N%)과 第4胃 濾液(X, ㎎ N%)中의 NH₃態 室素 濃度와의 關係는 다음 回歸 方程式으로 表示되었다. Y = 3.981 + 1.2783(±0.3736)X (r = 0.59, n-2=22) 8. 飼料 窒素 攝取量에 對한 補充飼料 alfalfa 葉 粉末의 小腸內 流入 NAN의 百分比는 當年葉, 2% HCHO處理 當年葉 및 無處理 貯藏葉의 順으로 각각 57.0%, 68.0% 및 65%로 推定되었다. 따라서 小腸內 流入 NAN은 2% HCHO處理 當年葉이 無處理보다 19%, 貯藏葉은 當年葉 無處理보다 14% 程度 增加된 것으로 推定된다. 9. 貯藏葉 補充時 音機物 消化率은 當年葉을 補充할 때 보다 約 1% 減少되고 當年葉 및 貯藏葉에 HCHO處理는 葉中 有機物의 排泄量을 0∼3.4% 程度 增加시키는 傾向이었으나 有意差는 當年葉과 貯藏葉 間에만 認定되었다. 10. 反芻胃液 및 第4胃液의 各 腸器 通過率, 反芻胃 容量 및 그 內容物의 滯在時間은 處理間有意差가 認定되지 않았다. 1. The OM out-put in the faeces was about 3% unit higher with the Old than that with the New, while with the HCHO treated meals there was only a slightly and insignificantly increasing tendency in the OM out-put. 2. No significant differences in the liquor flow rate of the rumen and the abomasum fluid, and in the rumen volume and retention time were found between the treatments. 3. The ruminal NH₃-N concentration in the Old was about 17.5% unit higher (P<0.01) than that in the New, while the New + 2% HCHO was about 7.0% unit (P<0.10) and the Old + 4% HCHO was about 34% lower (P<0.01) than those in the untreated-New and Old. 4. The amount of NH₃-N excreted from the rumen in the Old was 18% unit higher (P<0.01) than that in the New, and that in the New + 2% HCHO about 6% unit was lower, though insignificant, than that in the New, while that in the Old + 4% HCHO was about 32% unit lower (P<0.01) than that in the Old. 5. The NAN content of the intestine in the New was about 6% unit higher (P<0.10) than that in the Old, while in the New + 2% HCHO and the Old + 4% HCHO about 6% unit (P<0.05) and 17% unit (P<0.01) were higher than those in the New and the Old, respectively. 6. The amount of NAN excreted from the abomasum in the Old was about 9% unit higher (P<0.05) than that in the New, while the New + 2% HCHO resulted about 6% unit higher (P<0.01) NAN excretion than the New. 7. The NAN digested in the intestine per 100g of dietary nitrogen intake in the Old was about 10% unit higher (P<0.10) than that in the New, while in the New + 2% HCHO about 6% unit was higher (P<0.05) than that in the New. 8. The fecal nitrogen output per 100g of dietary nitrogen intake in the Old was about 8% unit (P<0.01), in the New + 2% HCHO was about 6% unit and in the Old + 4% HCHO about 2.4% unit was higher (P<0.10) than in the New and the Old. 9. The significant correlation between the concentrations of NH₃-N in the abomasal filtrates and those in the ruminal fluids permitted to draw a predictive equation by regression analysis as follows: y = 3.981 + 1.2783(+0.3736) X, where, Y = Ruminal NH₃-N concentration (㎎ N%) X= NH₃-N concentration in abomasal filtrates (㎎ N%), (n-2=22) and (r=0.59) 10. The percent of NAN entered the intestines over supplemental leaf meal nitrogen intake in the New, the New + 2% HGHO and the Old were 57.0, 68.0 and 65%, respectively. The NAN entered the intestine in the New + 2% HCHO and the Old were 19% and 14% higher than those in the New, respectively.

Application of Biotechnology to the Study of Nematodes

Ash,Lawrence R. INSTITUTE OF TROPICAL MEDICINE YONSEI UNIVERSITY 1989 YONSEI REPORTS ON TROPICAL MEDICINE Vol.20 No.1

Without question, we are in a new era of parasitologic research, Im my summary of some of the biotechnological developments that have been applied to the study of nematodes I have touched on some of the highlights but certainly not all. Time could have been spent equally on many other topics. Cryopreservation techniques have great relevance for many studies on all parasites, including nematodes. The development of vaccines and newer approaches to the development of effective chemotherapeutic agents dovetail with advances in immunology, biochemistry, and parasite physiology, In Southeast Asia, with the presense of the wide range of animal and human parasites, the opportunities for basic research and the application of new methodologies to parasites is probably still unlimited. It should prove to be an exciting time as we delve more deeply into the mysteries of these fascinating organisms and into the mysteries of these fascinating organisms and how we can outwit them to lead to their control

Stochastic processes in the musification of cellular automata

Kingsley Ash(킹슬리 애시),Nikos Stavropoulos(니코스 스타브로폴로스) 한국전자음악협회 2012 에밀레 Vol.10 No.-

이 글은 실시간으로 악보를 만들며 소리 파일들을 구동하고 처리함으로써 ‘상호 작용을 통해 음을 생산하는 작곡interactive generative composition’을 위한 시스템인 ‘라이브셀Livecell’에 대하여 논하고 있다. 이를 위해 저자의 이론적 근거를 제시하고, 맥락에 따른 셀룰러 오토마타cellular automata의 적용을 예시하며, 응용 프로그램의 구조 설계를 밝힌다. 또한 셀룰러 오토마타의 음악화에 대한 접근 방법과 악보에서 데이터 간의 관계를 제시하며, 악보의 제작과 그 디스플레이를 비롯한 인터페이스 디자인에 대해 기술한 후, 음악적 최종 생산물에 대한 관찰과 향후 발전에 대한 논의로 끝을 맺는다. This paper discusses Livecell, a system for interactive generative composition through real?.time score generation as well as the triggering and treatment of sound files. The paper outlines the authors’ rationale, discusses the use of cellular automata in this context and provides an insight into the application’s structural design. The authors summarise their approach to CA musification, the representation of data relations in a musical score, and interface design as well as score generation and display. The paper concludes with observations on the musical output and discussion of future developments.

Analysis of Generalized Impact Factors and the Indices of Journals

Abbas, Ash Mohammad Korea Information Processing Society 2011 Journal of information processing systems Vol.7 No.2

Analyzing the relationships among the parameters for quantifying the quality of research published in journals is a challenging task. In this paper, we analyze the relationships between the impact factor, h-index, and g-index of a journal. To keep our analysis simple and easy to understand, we consider a generalized version of the impact factor where there is no time window. In the absence of the time window, the impact factor converges to the number of citations received per paper. This is not only justified for the impact factor, it also simplifies the analysis of the h-index and g-index as well because addition of a time window in the form of years complicates the computation of indices too. We derive the expressions for the relationships among impact factor, h index, and g-index and validate them using a given set of publication-citation data.
