수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

濟州地域 部落共同 牧場의 草地狀態 및 氣象現況이 飼育中인 家畜의 增體에 미치는 영향을 究明하기 위해 6個部落 共同牧場(영남,해안,회천,용강,오라,하원)에서 成牝年 415두의 體重과 그 牧場의 草地狀態를 調査한 結果는 다음과 같다. 1. 試驗이 實施되는 部落共同牧場의 草地面積 197.8ha중 改良草地比率은 66%이며 頭當面積은 0.9ha였다. 2. 名 牧場 共히 牧草 보다 野草의 乾物收量이 높으며 2回 收穫 中 牧草는 初期收量(1734㎏/ha>1459㎏/ha)이 높았고 野草는 後期收量이 (2025kg/ha<4734kg/ha)높았다. 3. 野草의 粗蛋白質 含量은 施肥草地(12.05%)가 無肥草地(7.87%) 보다 높았으나 牧草는 施肥에 關係없이 비슷한 傾向이였으며 粗纖維含量은 無肥草地가 높았다. 4. 月平均 增體量은 6月 347.0kg, 7月 358.5kg, 8月 384.5kg, 9月 414.2kg, 10月 421.8kg로서 放牧期間中 頭當 總 增體量은 74.8kg이며 月別 1日 增體幅은 9月에 頭當 1.05㎏으로서 本 試驗期間中에 가장 크다. 5. 日當 平均 增體量은 하원 0.89kg, 해안 0.81kg 영남 0.71kg, 회천 0.60kg, 용강 0.58kg과 오라 0.15kg 順位였으며 全體平均 日當增體量은 0.61kg이였다. The study was carried out to investigate the effect of grass quality and climate on weight gain. Six co-operative village farms were surveged which reared Korean native and Korean cross-bred cows. The results obtained were as follows; 1. The farms examined had 66% improved pasture and a stocking rate of 0.9ha per head. 2. On all the farms, the total dry matter content of native pasture was more than that of the improved pasture. 3. In the case of native pasture the crude protein content when fertilized(12.05% cp compared to 7.87%). On the other hand, there was no difference in crude protein content between fertilized improved pasture and non-fertilized. The crude fibre content of improved and unimproved pasture decreases when fertilized. 4. Body weights during June, July, August, September and October were 347.0kg, 358.5kg, 384.5kg, 414.2kg and 421.8kg respectively. 5. The average daily weight gain on each farm was 0.89kg on Hawoen, 0.81kg on Yeong Nam, 0.71kg on Hoicheon, 0.60kg on Young Kang and 0.15kg on Oh Ra: The total weight gain of all the cows on all the farms was 76.8kg with an average daily weight gain of 0.6kg per cow.

Acccrding to the investigation of reproductive status and disorders in Cheju native cattle, the delayrd puberty, fist calving age in heifer, and thealternate year calving cow dric to anrstrus following calving were observed more frequently on this island. This study, therefore. was carried out to investigate the effect of PMS as a method of trenstment for the cows with ovarian hypoplasia and atrophy. For the 15 cows with ovarian hypoplasia, the blood was tested and 40 cows of anestrus due to ovarian hypoplasia and atrophy were selected to treat with PMS. The results obtained were as follows. 1. The blood test indicated that cows of the ovarian hypoplasia appeared to havc lower scriim protein and calcium level than that of normal cow. Espercially abnormality inA/G ratio and Ca/P ratio in Holstein was found. 2. Trensment of PMS into 40 cows with the ovaridn atrophy and hvpoplasia showcd estrus average 6.7 days after the final hormone injection. 3. Total 38 cow were conceived by PMS (100 IU) hormone treatment; 26 cows (64.4%) at the first estrus. It cow (30.6%) at the second estrus and the remainder at the third estrus. 4. The above resolts inkicated that treatment of PMS hormone into cow with ovarion hypoplesia and atrophy was effertive for inducing estrus and conception.

Unilateral pulmonary vein atresia is a rare congenital disease and is frequently associated with intracardiac anomalies. It is usually diagnosed in childhood and is very rarely diagnosed in adulthood. A case of unilateral pulmonary vein atresia in a 20-year old female is de- scribed. The relevant findings were symptoms of exertional dyspnea, roentgenographic evidence of decreased lung volume, increased interstitial infiltration with septal lines in the involved side (right), and aoscence of blood flow in a radionuclide perfusion scan. Pulmonary angiography showed an extremely small right pulmonary artery and thining of the peripheral branches, and nonvisualization of the draining pulmonary veins. Bronchial arteriography showed rommunication between the bronchial artery and the right pulmonary artery and it was drained to the left pulmonary artery. Cardiac catheterization showed no intracardiac anomaly. The right bronchography was normal; pulmonary function studies showed a pure restrictive pattern and markedly in creased physiologic dead space. MRI showed no visible right pulmonary vein.

The technique of bovine embryo transfer in Korea began very late compare toother countries and related researches have also been carried out in several limited places only as a foundmental works. Especially, the studies on embryo freezing which play an important part on the spreading of bovine embryo transfer , evaluation of embryo and its dead-alive determination have almost not been done up to the present time. Therefore, for the improvement of the spread of embryo transfer experiment station, national breeding station as well as related industries and universities should perform mom works with dividing specialization from now on. Conclusively, by concentrating on such ultramodern technology as micromanipulation of mammalian early embryos and its transferring, contribution on the systematic spreading of embryo transfer in Korea and improvement of domestic animals performances together with the development of high characteristic livestock should be accomplished.

舍飼期間中 濟州韓牛의 飼料給與狀態가 體重變化, 繁殖狀況 및 隔年分娩牛에 미치는 影響을 調査하기 爲하여 濟州道內 六個部落에서 飼育되고 있는 供試畜 400餘頭를 調査한 結果는 다음과 같다. 冬期間 飼料給與狀態에서는 各部落別 큰 差異는 없었고 補充飼料를 1kg以上 給與하는 戶數는 全體의 4.8%로 매우 낮았으며 糠類飼料(單用)을 每日 若干씩 주고 있는 農家는 46.6%로 過去보다 增加르 보였으나 乾草만으로 飼育하는 農家는 48.6%로서 漸次減少 現象을 보이고 있다. 冬期間 月別體重變化는 大部分 一月에서 四月까지는 大體로 20∼30kg 減少 趨勢를 보이다가 放牧場에 入殖된 五月에는 約 10∼20kg 增加되는 傾向을 보였으며 濟州韓牛와 交雜種間의 比較에서는 Brahman 交雜種이 體重變化가 가장 적은 反面 韓牛와 Santa 交雜種은 體重 減少幅이 極甚하였다. 未經産牛에서 初分娩月齡은 가장 빠른 地域이 38.2個月이 었고 늦은 地域은 40.5個月로 2個月差異가 있었으며 經産牛의 分娩後 初發情 再歸日에에서 隔年分娩牛를 除外했을 때는 平均 90.4日이고 地域別 10-20日差가 있었는데 反하여 隔年分娩牛를 包含시켰을때에는 平均 174.2日로 상당히 길었으며 地域別 差異도 甚하였음을 보여 주었다. 隔年 分娩牛의 發生率은 地域別로 볼 때 平均 13%에서 23%의 差異를 나타내고 있었으나 年度別로 比較할 때는 1980年度 9.5%, 1981年度 33.5%, 1982年度 11.9%로 隔差가 甚하였다. To investigate the effect of giving different feeds, during the winter, on body weight changes, reproductive performence and alternate year calving cows. 400 Jeju native and cross bred cows and heifers housed in villages were studied. Results showed no appreciable difference amongst the 6 villages feeding different foods during the winter period. Percentage of farms feeding various brans, over 1kg per day, was 4.8% ; a small quantity(0.5kg) of various brans was fed daily to 46.6% and those feeding only natural hay, 48.6%. The number of villages feeding various brans is increasing and those feeding hay decreasing. Cattle weights decreased by 20-30kg monthly per head during the winter feeding period(January-April) but by May increased in the range of 10-20kg per head with arrival of the new grass. Comparison of monthly body weight changes of Jeiu native cows and cross breds, Brahman cross breds showed the least body weight changes during winter while Native and Santa cross bred cows the weight changes were considerable. The average age at first calving, in the regional groups, varied by two months and when averaged out was 38.2 and 40.5 months in the early and late regions respectively. There was an average of 90.4 days from calving to first estrus excluding alternative year calving cows which had an avarage of 174.2 days from calving to first estrus. The alternate year calving percentages averaged from 13% to 23% in regional groups, and were 9.5% in 1980, 33.5% in 1981 and 11.9% in 1982.
