Old documents, it is right thing to define one's cultural level, and it also reflect history which is the spirit of our racial and the very deep root of out power. Old documents, it is not a simple record for the past. We can redefine our history though the ancient documents, and even more it make us to succeed and develop our national culture capacity. Nowadays Korea is being shaken by distorting our history coming from China and Japan. To get the historical consciousness of the china and japan right way, there will be necessarily needed a kind of data to prove and show the right direction. The diary written by the commander of the Joseon Army, which was discovered at the early of this year, tell the untold story what was done by Japanese army at the Je-Am Ri(a kind of sub-township) during the March 1st. campaign. That record also show us the Japanese army's attempt to conceal the process of the Je-Am Ri's massacre event and to conciliate racial activists. And this will be a guide for the research to the Joseon recent and contemporary history. Therefore we can not look down on the importance of the ancient documents. There are huge mounts of documents and books at the abroad. Because of the political problem, those are still away from our hands and it is really heart-stricken. We can not treat ancient documents just like waste in the garbage can and leave it thoughtlessly. It will be a medium to solve the distorted history problem and an example to straighten our history. So we have to evaluate the value of the historical record well, and then we should preserve and apply it. This issue ought to solve through the politics and policy sector above the academic interests. But we can not blindly see ancient documents as a only things for showing the truth of the history. We have to see other historically worthful data with old documents and try to excavate and restore. So, at this research, I study the value of the old documents and its reservation necessity.

보리가루에서 분리한 β-Glucan의 생리적 기능성

오희정,이서래 이화여자대학교 생명과학연구소 1996 생명과학연구논문집 Vol.7 No.-

보리가루로부터 β-glucan을 추출, 정제하여 그의 소화관내 생리적 기능성을 알아보기 위해 반투막을 이용한 in vitro 실험을 수행하였다. 보리가루로부터 β-glucan을 6.2%의 수율로 정제하였으며 그의 순도를 확인한 결과 총 식이섬유 81.6%, 수용성 식이섬유 72.9%, 불용성 식이섬유 8.7%, 수분 8.5%, 단백질 2.5%, 회분 7.4%였다. β-Glucan 제품의 수분보유력은 1g의 건조물당 6g이었다. 투석막을 이용하여 β-glucan 제품의 glucose 흡수 지연효과를 살펴 본 결과 β-glucan을 3% 첨가한 경우 투석 30분이 경과되었을 때 glucose retardation index가 13.5%였고 시간이 경과할수록 그 효과는 감소하여 투석 2시간 후에는 그 효과가 거의 없는 것으로 나타났다. Bile acid 흡수 지연 효과를 살펴 본 결과 투석 30분이 경과되었을 때 bile acid retardation index는 β-glucan이 1,3,5% 첨가된 경우 각각 3,12,18% 수준으로 같은 시간이 경과되었을 때의 glucose 흡수 지연효과보다 더 크게 나타났으며 시간이 경과할수록 그 효과가 감소하였다. In order to prove physiological function of β-glucan isolated from barley flour by enzymatic method, in vitro experiments simulating the passive membrane transport of gastrointestinal tract were carried out out using dialysis membrane. The yield of β-glucan from barley flour was 6.2% and its constituents were determined to give 81.6% total dietary fiber, 72.9% soluble dietary fiber, 8.7% insoluble dietary fiber, 8.5% moisture, 2.5% protein and 7.4% ash. The water holding capacity of the β-glucan preparation was 6g water/g dry material. The glucose retardation index after 30 minute dialysis was 13.5% in the presence of 3% β-glucan. As the dialysis period became longer, the retarding effect toward glucose absorption decreased and the effect was close to zero after 2 hour dialysis. The bile acid retardation index after 30 minute dialysis was 3,12 and 18% in the presence of 1,3 and 5% β-glucan, respectively. The effect was higher than the glucose retardation index and decreased as the dialysis time elapsed.

성찰 일지 분석을 통한 마이크로티칭 수업 사례 연구

오희정 이화여자대학교 교과교육연구소 2020 교과교육학연구 Vol.24 No.3

This study aims to investigate the effectiveness of employing microteaching as a way of providing teaching experiences to and enhancing teaching skills of pre-service Secondary English teachers. While previous studies focused more on analyzing the effectiveness of microteaching or analyzing only the reflection of fragmentary processes, this study ran process-oriented microteaching, with enhanced activities at each stage, from the preparation of lesson plans to the microteaching demonstration. In particular, to strengthen the process of lesson planning, several drafts were made and updated with peer and professor feedback. Microteaching was conducted individually to give a chance for each individual to enhance their teaching skills. At each stage of the microteaching course during the semester, pre-service teachers recorded their experiences and feelings in their reflection journals. The results showed that microteaching helped pre-service teachers improve their teaching abilities, improve awareness of teaching processes and feel more confident in teaching in English. The pre-service teachers said that it was not easy, but they could enhance the quality of the lessons by practicing the theory and practice step by step and revising the lesson plans several times through communicating with their peers. They preferred to do class demonstrations individually, but they learned a lot from feedback from other students. The operation of process-oriented microteaching in this study was found to be helpful in promoting the teaching ability of pre-service teachers. 본 연구는 수업 능력을 갖춘 예비 영어교사를 양성하는 효과적인 마이크로티칭 운영 방법을 탐색하기 위해 시행되었다. 기존의 연구에서는 대개 수업 시연을 하고 그 결과를 분석하거나 단편적인 과정에 대한 성찰 일지만을 분석한 것과는 달리, 본 연구에서는 수업 지도안 작성 단계부터 수업 시연까지 단계별 활동을 강화한 과정중심적인 마이크로티칭을 운영하였다. 특히 수업 지도안 작성과정을 강화하기 위해 여러 차례에 걸쳐 수업 지도안을 작성하고 수업 시연 전에 동료 및 교수 평가를 거쳐 수정 보완하는 단계를 추가하였다. 그리고 수업 시연은 개별적으로 실시하여 각 개인이 충분히 수업 능력을 기를 수 있게 하였다. 한 학기 동안 진행된 과정의 단계마다 예비교사들은 경험하고 느낀 것을 성찰 일지에 기록했다. 그 성찰 일지로 예비교사들이 실제로 경험한 마이크로티칭 수업의 결과를 살펴본 결과, 본 연구에서 시행한 마이크로티칭 수업 운영방식은 예비교사들의 수업 구성 능력과 수업 시연 능력을 향상시켰고 영어로 수업을 하는 것에 대한 자신감을 느끼는 데 도움이 되었다. 예비교사들은 다소 부담이 되긴 했지만, 이론과 실습을 병행해서 단계적으로 연습하고 수업 지도안을 여러 번 수정하는 과정이 있어 수업의 완성도를 높일 수 있었다고 했다. 수업 시연은 개별적으로 하는 것을 선호하지만, 수업 시연을 준비하는 과정에서 다른 학생들과 함께 피드백하며 많은 것을 배울 수 있었다고도 했다. 이처럼 본 연구에서 과정중심적 방식으로 마이크로티칭을 운영한 방법은 예비 영어교사의 수업 능력을 향상시키는 데 도움이 되었다.

This study was carried out to identify the chromosome morphological structure and G-C-banding pattern of Korean native fowl. The samples used in this study were early chick embryos, and the method of chromosome analysis quote from the protocal of Ohio Univ.with more or less modified. In each of micro chromosome morphology, the arm-ratio, centromeric index, and relative length of Korean native fowl were more or less different from improved breed, but the designations were the same. In size ratio of each chromosome per 1st chromosome, 3rd and 6th were 0.552 and 0.198, respectively, and Z chromosome was a little larger than 4th. Hereafter, the chromosome analysis by size should be attribute to estimate more accurate karyotype along with methods by length and place of centromere. The graphical pecks, by densitometer recording, were 21, 14, 12, 8, 11 and 4 in G-banded, and 16, 13, 9, 9, 9 and 4 in G-banded in each chromosome number of 1st, 2nd, 3rd, 4th, Z and 5th, respectively.

This study was carried nut to obtain the frequencies and patterns of chromosomal aberration in the early embryos and to investigate the relationship of hatchability and chromosomal aberration. Total of 690 fertile eggs from broiler breed, layer breeds, Korean native chick, Ogolgye and Korean ring-necked pheasant were examined. Metaphase spreads were prepared from 16-to 18 hours embryos. The procedures were colchicine treatment, hypotonic, fixation and then air-drying method. The karyotypes were made from each of clear metaphase spread. A total of 520 embryos were successfully analyzed, of which 491 were diploid, 4 were haploid, 12 were haploid-diploid mosaic. I was triploid, 3 were aneuploid, 8 were aneuplid mosaic and I was triploid-3 tetrasomy. The average frequency of poultry chromosomal aberration was 5.6% which included 7 of broiler breed, 6.8% of Korean native chick, 5.9%, of Ogolgye, 5.0% of Korean ring-necked pheasant, and 3.7% of layer breed. The incidence of highest embryonic dead was Korean native chick. The hatchahility of layer breed which had the lowest incidence of chromosomal aberration was 65%. Others were 57% of meat breed, 49% of Ogolgye, and 43% of Korean native chick. Thcsc showed the tendency that the higher incidence of chromosomal aberration had decreasing hatchability. It was also certain that the frequencies of embryonic chromosomal aberration and of early embryonic dead seemed to be closely and positively correlated.

吳熙晶 順天大學校 農業科學硏究所 1992 農業科學硏究 Vol.6 No.-

In order to estimate genetic correlation, the 5 and 8 weeks of aged broilers were examined in this study. One handred male broiler chickens from 20sires and 50 dams were slaughtered at 35 and 49 days of age. One progeny per dam(n=50) were used at each age. In case of 35 day-old broilers are presented first and 49 day-old broilers second, the data of each trait wee as follows; live weight : 1425,2292g, carcass weight : 932,1627g, abdominal fat weight : 27.3, 56.7g, abdominal fat / live weight% : 1.98, 2.59, and abdominal fat / carcass weght% : 3.17, 3.60. There were significantly different in live weight, carcass weight, abdominal fat weight(P<0.01), and abdominal fat / live weight% (P<0.05). The genctic correlations between 5 and 7 weeks of age were 0,54(live weight), 0.64(carcass weight), 0.47 (abdominal fat weight), 0.43(abdominal fat/live weight %), and 0.43(abdominal fat/carcass weight %) respeatively. The results are interpreted into the data estimated from 5 week-old broilers may be useful in a selection program to improve the live weight of 7 weeks of aged briler.

本 試驗은 Broiler병아리의 6 週齡과 8 週齡에서 調査한 生體重, 屠體重, 腹脂肪重을 資料로 週齡間 有意差를 알아보고 遺傳相關의 程度를 測定해 냄으로써 早期選拔의 可能性을 타진하기 위한 것이었다. 그 結果는 다음과 같았다. 1. 各 形質에 對한 週齡別 測定値 平均이 生체重 1465, 2372g: 屠體重952, 1820g: 腹腔脂肪重0.65, 63.7g:生體重에 대한 腹脂重% 2.09, 2.69:屠體重에 대한 脂脂重% 3.35,3.62로서 生體重, 屠體重, 그리고 腹脂重等은 높은 有意差를 보였다. 2. 週齡間 遺傳相關은 生體重에 0.75, 屠體重 0.66, 腹脂重 0.45, 生體重에 對한 腹脂重% 0.41이었다. 以上의 測定値로 보아 6週齡 Broiler병아리에 對한 資料는 8週齡 生體重을 改良하기 爲한 育種 計劃에 利用할 수 있을 것으로 思料된다. The genetic relatilnship beween traits in broiler chickens at 6 and 8 weeks of age was determined. One-hundred male broiler chickens from 20 sires and 100 dams with 2 full sibs/dam were slaughttered at 42 and 56 days of age. One offspring per dam was slaughtered at each age. Means of 42day-old chickens are presented first and 55-day-old chickens second:Live weights 1465,2372g:Carcass weights 952, 1820g:abdominal fat weights 30.65,63.7g:percent abdominal fat/live weight 2.09, 2.69:percent abdominal fat/carcass weight 3.35, 3.62. The means were different (p<0.01) between weeks for live weight, and abdominal fat weight. Genetic correlations betweed weeks were 0.57 (live weight), 0.66(carcass weight), 0.45(abdominal fat weight), 0.43(% abdominal fat/live weight), and 0.41(%abdominal fat/carcass weight). Records obtained on 6-week-old full sibs might be useful in a selection program to improve traits in 8-weeks-old broiler chickens.

吳熙晶 順天大學校 1982 論文集 Vol.1 No.1

本 試驗은 밤 加工副産物인 塊皮粉의 飼料的 價値를 究明하고자 試圖되었다. Broiler配合 飼料를 밤 塊皮粉으로 5∼10 그리고 15% 代置利用시켰을 때 慣用區에 比較하여 增體量, 飼料攝取量 그리고 飼料效率 等이 어떻게 差異가 나타나는가를 調査하였든 바 結果는 다음과 같았다. 1. 밤 塊皮粉의 代置水準이 높을수록 飼料攝取量이 약간씩 低下하여 飼料攝取率이, A : 99%, B : 97%, C : 96%이었다. 2. 增體量에 있어서도 慣用區에 比하여 A : -22g, B : -59g, C : -114g로서 C區에서만 P<0.5로 나타났다. 3. 飼料效率은 慣用區 2.2에 比하여 모두 0.1이내의 範圍에서 낮아져 역시 有意性이 없었다. 4. 탄닌 含量이 가장 많았던 C區에서 軟便 現象이 나타났다. 以上의 結果로 볼 때 밤 塊皮粉은 broiler 配合飼料에 10% 水準의 代置는 바람직하다고 생각된다. In order to evaluate the feed value of dried chest·nut by-product for broiler chicks, a feeding trail was conducted for 6 weeks(from 2 to 8 weeks of age) with a total of 180 heads of broiler chicks replacing broiler ration by a dried chestnut by-product at the levels of 0, 5, 10 and 15% on the weight basis and the experiments researched in to body gain, feed intake and feed efficiency. The results obtained are summarized as follows; 1. Feed intake per chick for 0, 5, 10 and 15%levels of dried chestnut by-product were 3,238, 3,225, 3,132 and 3,120kg or it's rations were 100, 99, 97 and 96% respectively and showed the tendency to decrease as the dried chestnut by-product lelevel increased. 2. Average body gains per chick were 1,472, 1,446, 1,411 and 1,353kg respectively. there was only a significant(p<.05) in the lotc. 3. The amounts of feed required per kg weight gain were 2.2, 2.23, 2.22 and 2.3kg respectively and tended to increase as the dried chestnut by-product level increased. 4. Tannic acid in the chestnut by-product was effective to prevent lot A and B from wet feces, but there was slightly wet feces in the lotc. Above results indicated that up to 10% level of dried chestnut by-product in the broiler ration gave them satisfactory body gain, feed intake and feed requirement.
