韓鳳羽,金容斗,李秉達 東亞大學校 1968 東亞論叢 Vol.5 No.-

本 調査硏究는 酪農經營의 合理化와 酪農所得의 極大化를 圖謀하기 爲한 方策을 究明하기 爲하여 着手한 것으로 釜山市內 酪農家中에서 20戶를 選定하여 1967年 5月 1日부터 11月 30日까지 經營實態의 調査와 分析을 通하여 經營의 改善點을 發見하고 經營의 合理化 方案을 提示하였는데 그 結果를 要約하면 다음과 같다. 1. 飼育頭數 225頭中 窄乳牛 120頭, 乾乳牛 18頭, 育成牛(♂包含) 87頭며 窄乳牛率(窄乳牛 頭數/總飼養 頭數×100) 53% 乾乳牛率(乾乳牛 頭數/成牛 頭數×100) 13% 育成牛率(育成牛 頭數/成牛 頭數×100) 63%였다. 2. 窄乳牛(乾乳牛 包含) 138頭의 1頭 年平均 産乳量은 3,690kg였다. 3. 窄乳牛에 對한 飼料給與量은 1日 1頭 平均 濃厚飼料 9.4kg 粗飼料(風乾物) 9.0kg이며 養分含量은 TDN 9.09kg, DCP 1.24kg인데 標準(NRC)보다 TDN 53%, DCP 82%를 過量供給하고 있다. 한편 粗飼料量이 全體飼料量의 50% 未滿인데 이것은 經濟面이나 乳牛能力 增進面으로 볼 때 不利함으로 60% 以上으로 하여야 한다. 4. 生産費의 項目別 比率은 飼料費 44%, 勞動費 27%, 肥料 및 材料費 5%, 賃貸料 및 地代 5%, 乳牛 및 建物償却費 16%, 小農具費 및 其他 3%로 되어있다. 5. 牛乳生産費는 牛乳 1kg當 平均 32.25원인데 1kg當 乳價가 43.2원이기 때문에 牛乳 1kg當 10.95원의 收益을 얻고 있는데 牛乳 1kg當 28원 以下가 되도록 努力하여야 한다. 6.1頭當 年平均 勞動時間이 470時間인데 1人이 8~10頭를 管理하려면 365時間 以下가 되어야 한다. 7. 調査한 酪農家中 黑字經營이 14戶, 赤子經營이 6戶인바 年間 1頭當 純收益이 平均 2萬원으로 所得率이 낮았다. 8. 酪農經營의 診斷에 있어서 牛乳代와 飼料 및 勞動費만을 가지고 經營의 採算點을 生産面에서 把握하는 것은 簡易한 判斷을 爲하여 意義 있는 일이며 今般 調査한 結果를 보면 牛乳代 17,596원, 粗收益中 牛乳代 比率 86%, 飼料 및 勞動費 11,781千원, 生産費中 飼料 및 勞動費 比率 71%이므로 採算指數(牛乳代÷粗收益中 牛乳代比率/飼料 및 勞動費 ÷生産費中 飼料 및 勞動費比率=粗收益/生産費)는 1.29가 된다. 1頭當 年 35,000원의 所得을 爲해서는 採算指數가 1.5가 넘어야 한다. 蛇足 본 調査硏究는 1967年度 文敎部 學術硏究 助成費로 이루어진 것으로 硏究費를 補助해준 文敎當局에 對하여 深甚한 謝意를 表하는 바이다. 또한 調査에 協力하여 주신 釜山市牛乳協同組合과 釜山市 酪農家 畜産同人 諸位에 對하여 깊은 感謝를 드리는 바이다. This report aims to get a rationalization of dairy fanning and maximization of dairy income. In order to gain the suvey, I have selected -'0 dairy farm-houses in Pusan city. Then I have been caught some points of farm improvement and presented some rational plan of dairy farming through farm business survey and analysis from 1 May to 30 Nov. 1967. The summalized results of the research are as follows; 1. Out of 225 heads were milking-cow 120 heads, dry-up-cow 18 heads, rasing cattle 87 heads. 2. Average milk yield per a year of 138 heads milking-cow(including dry-up-cow) was 3.690kg. 3. Average 9.4kg of concentrate and 9.Okg of rougiiage(air dry matter) for milking-cow per a head were the daily feeding ration, nutrient content was 9.09kg of TDN and 1.24. kg of DCP, these content were more 53% of TDN and 82% of DCP than feeding standard (NRC). 4. The feed cost was 44%, the cost of labor 27%, manure and materials cost 5%, charge for renting and land rent 5%, depreciation cost of dairy cattle and building 16%, cost of small farming tools and other cost 3% of the total production cost. 5. Average production cost of milk per 1kg of milk was 32.25 won. average profit per 1kg of milk was 10.95 won (milk price was 43.2 won per 1kg). But it may be less than 28 won per 1kg of milk. 6. Average working time per 1 head of a year was 470 hours. But it may be less than 350 hours for the management of 8~10 heads per 1 person. 7. Out of the dairy farm-households surveyed, 11 houses were in the blade farming and 6 houses were in the red farming. Average pure profit per 1 head of a year was gained 20 thousand won that the rate of income may low. 8. Acording to the method of a simply commercial profit was gained to the rate of milk price for the gross profit and the rate of feed and labor cost for the production cost. Average commercial profit index has show 1.29 in the result of this farm survey. Commercial Profit index = milk price/rate of milk price for gross profit/cost of feed & labor/rate of feed & labor cost for production cost x 100 =17,956 thousand won/0.86/11,781 thousand won/0.71 x 100=1.29 It may be over 1.5 of the cmmercial profit index for 35 thousand won of the income per 1 head of a year.

朴奉斗,韓聖愚,尹志洪 慶北大學校 産業開發硏究所 1979 硏究報告 Vol.7 No.-

Cu-Ni thin films deposited on the glass by the vacuum evaporation method containing various concentrations of Cu have been studied its thermoelectricpower and electromotive force in the temperature range of 25―220℃. The thermoelectromotive force of pure Ni depends on the thickness of films to 1800, A° but Cu_0.8 Ni_0.2 to 1600A°. Cu―Ni films containing 15,20,25% of Cu were observed the effect of magnetic disorder. The variation of thermoelectricpower appeared in variious concentrations of Cu, its maximum value is 40μV in 45% of Cu. The linear dependence of thermoelectricpower on the temperature showed from 50% to 90% at concentration of Cu.

Photoacoustic Effects on Material-coated window

朴奉斗,尹志洪,韓聖愚 慶北大學校 産業開發硏究所 1979 硏究報告 Vol.7 No.-

Photoacoustic effect was studied with the air cell and tungsten lamp. The air cell had a material-coated window. As the coating material, one of the following materials was used; the lamp black, copper, nickel and aluminum. The incident light was chopped by the rotating disc, and entered through the material-coated window. The produced photoacoustic signal intensity is approximately inversely proportional to the chopping frequency. This effect was the same as that when the chopped light entered into the air cell from the opposite side, gas side. The signal intensity, however, was much smaller than that of tho light incident from the oppsite side. The photoacoustic signal intensity was varied with the thickness and kinds of coated material. In the case of aluminum the intensity was rapidly decreased when thickness increased. In the case of copper, however, the intensity was increased until the thickness increased to a certain value, and over this value the intensity was decreased slowly.

朴奉斗,尹志洪,韓聖愚 경북대학교 과학교육연구소 1978 科學敎育硏究誌 Vol.2 No.-

Quantitative analysis of the static electricity charged on the water dropper has been performed with an electrometer and recorder. Experiments were carried out over various parameters such as nozzle diameter, water pressure, different kinds of liquids and temperature with time. The accumulated charge on the cans of the water dropper was related to the size of nozzle outlet and hydrostatic pressure, but were independent of the temperature of liquids. There was no charge, of course, on the nonpolarized molecules such as C_6H_6, CCl_4, and kerosen fuel.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
