1,241頌의 Colliedale種 緬羊으로 부터 얻어진 資料에 근거하여 性別, 産存型, 年齡 및 剪毛年度가 産毛量에 미치는 影響을 推定하였다. 本 硏究에 利用된 緬羊은 1962年부터 1976年까지 高嶺地試驗場에서 동育되었다. 資料分析을 위하여 Model에는 性別, 産存型, 年令 및 剪毛年度의 主效果가 포함되었고 相互作用은 존재하지 않는 것으로 간주하였다. 1. 産毛量의 最小自乘平均은 4.01kg이었다. 2. 性別, 年齡 및 剪毛年度의 效果는 모두 1% 水準에서 統計的 有意性이 認定되었으나 産仔型의 效果는 有意差가 認定되지 않았다. 3. 숫양은 암양에 비하여 平均 1.01kg의 羊毛를 터 生産하였다. 4. 그러나, 7歲까지는 年齡이 增加함에 따라 産毛量이 增加되었으나 그 以後에는 점차 감소하는 傾向을 보였다. 5. 剪毛年度에 對하여는 年度가 경과됨에 따라 다소 增加되었으나 약간의 진폭을 보이는게 특징이었다. On the basis of data obtained from 1,241 Corriedale sheep, effects of sex, type of birth, age and year of shearing on the fleece weight were estimated. The sheep were reared at the Alpine Experiment Station over a period of 14 years from 1962 through 1976. The linear model used to analyze the data included the main effects without interaction term. Overall least square mean for the weight of greasy wool was 4.0lkg. Effects of sex, age and year of shearing were all statistically significant at 1% level, whereas effect of birth type was not. Rams produced 1.0lkg more wool on the average than ewes. There was a tendency that greasy wool yield increased up to 7 years of age then decreased thereafter. Effect of shearing year on the wool yield showed that it increased as the year progressed with some degree of fluctuation.

子宮의 成長에 대한 胚의 影響을 알아보기 위하여 한쪽 子宮角에만 姙娠시킨 末經産豚의 姙娠된 子宮角과 姙娠안된 子宮角의 길이, 무게 및 직경을 北較하였다. 成熟前 암돼지 82頭를 5個月令에 한쪽 卵巢를 除去하였고 또 卵巢를 除去한쪽의 子宮角과 子宮體 接合部位를 結??하였다. 이러한 末經産豚을 種付시켜서 임신 9, 12, 15, 21 24 및 27 日로 무작위로 배치하여 한쪽 子宮角에 姙娠된 末境産豚의 姙娠된 쪽의 子宮角과 姙娠안된쪽의 子宮角간의 子宮길이, 무게, 직경의 絶對差와 北를 分析하였다. 그 結果 姙娠된쪽의 子宮角은 반대편의 姙娠안된 子宮角보다 姙娠 18日에는 40% 더 길었고 姙娠 27日까지로 계속 40% 더 길었으며 姙娠15日과 27日사이에 姙娠된 쪽의 子宮角은 子宮무게와 직경이 直線的으로 增加하였다(P<0.01). 胚는 姙娠18日頃에 子宮角의 길이, 무게 및 직경을 현저히 增加하게 하였으나 그 以前에는 그렇지 않았다.

신원집,백동훈 한국축산학회 1984 한국축산학회지 Vol.26 No.8

A study was conducted to find out the effects of calving season, parity, sex, birth type, sire, and location on gestation length in Korean native cow. The least square means were estimated from 192 cows raised at general farms in Chunchun-Myun and Sanseo-Myun, Jangsu, Chonbuk from 1981 to 1983. The results obtained are as follows: 1. The least square mean of gestation length of Korean native cow was 283.9 days. 2. There was no significant difference in gestation length among seasons, but the cows calved in spring and summer tended to maintain longer gestation than the cows calved in fall or winter. 3. The effect of parity also showed no significance, but the gestation length was increased as the parity progressed and was gradually decreased after 5th parity. 4. The effect of the sex of the fetus was not significant, but male calves were carried 0.5 days longer than females. 5. The effect of birth type showed significant differences at the 5% level, twin calves were carried about 5 days shorter than single calves (p$lt;0.05). 6. The effects of sire and location were not significant, but there were about 10 day differences among sires and 9 day differences between locations.

The authors present two cases of solitary thalamic abscess which were intially diagnosed as malignant thalamic glioma. After treatment with steroids and osmotic agents, the patients' clinical conditions improved after two to three days. However, sudden deterioration of consciousness level developed and the CT scan showed acute hydrocephalus with increment of thalamic low-density lesions. We performed extraventricular drainage and obtained CSF containing numerous inflammatory cells. This suggested the possibility that the lesion was a pyogenic abscess. which progressed to ventriculitis, rather than a malignant glioma. Stereotactic aspiration of the lesion confirmed thalamic abscess. These findings and review of previous reports of thalamic abscess suggested that early diagnosis and stereotactic drainage of the thalamic abscess is of primary importance.

소프트웨어 개발 과정의 여러 산출물 간의 일관성 유지는 최종 소프트웨어의 품질을 결정하는 중요한 요소가 되며, 운영단계의 유지보수 효율성에도 큰 영향을 미친다. 특히 구현 등 개발 후반부 활동을 진행 시 발견된 하나의 오류는 그 이전 단계의 다수의 산출물의 오류로 인한 파급 결과이므로, 발견된 오류의 원인(Cause)가 되는 이전 단계의 오류를 효과적으로 추적할 수 있는 체계가 요구된다. 본 논문에서는 한 산출물의 오류가 다른 어떤 산출물의 어떤 세부항목들의 어떤 오류로 인한 파급 결과 인지를 정의한 역 추적(Backtracking) 그래프를 제안하여, 개발자가 오류를 발견 시 관련 산출물과 항목을 신속히 파악할 수 있도록 한다. 이를 이용하여 산출물간의 일관성 유지 노력과 시간을 최소화하고 일관성 유지의 정확성을 높일 수 있다.

The result of microvascular decompression (MVD) in 105 consecutive cases is presented. The symptomatic vasculoneural compressions including tumor, vascular malformation, or aneurysm are excluded in this study group. The 41 patients with trigeminal neuralgia (TN) were all treated by posterior fossa exploration (PFE). Eighteen of them were treated with MVD only, another 14 with partial sensory rhizotomy (PSR) only, and in the other 9 patients, MVD and PSR were performed together. Sixty-two of 64 hemifacial spasm (HFS) cases were treated succesfully with MVD via PFE. However in one case of which the offending vessel was not identified, neurolysis was camed out. The other case who had both TN and HFS, died due to intraoperative cardiac arrest The result of operation was evaluated at one month after the operation. In TN, among thirty-nine (98%) patients who resulted in pain-improvement, 32 (82%) experienced complete resohition of the pain.,The rate of complete pain-relief was higher in the 'MVD only group' than in 'group with PSR': Amomg 62 (94%) cases of HFS, 29 (47%) patients obtained 'complete cure' and 'improvement-only' respectively only 4 (6%) patients had no change of the spasm. The preoperative clinical characteristics, intraoperative surgical fingdings and postoperative outcomes were itemized and analyzed to find out the prognostic factors. The our results are compared with others in the literature.

This study was conducted to investigate the rate of multiple births in Korean native cow treated with subcutaneous injection of 1000IU PMS on day 17 of estrus cycle followed by an intravenous injection of 1000IU HCG on the onset day of estrus. The results obtained were as follows: 1. The rate of normal estrus exhibited was 78.9% in the lst m 2nd parity cows and increased as the parity increased. 2. The mean duration from PMS Treatment to the onset of estrus was 4.3 days grad was no significant difference among tire parities. 3. The mean number of matured follicles per cow treated was 1.2 and was no significant difference among the parities. 4. The rates of multiple birts were 4.8%, 40.0% and 23.9% for 1st to 2nd parity, over 3rd parity and over all, respectively, and were increased as the parities increased.

This study was carried out to investigate the effects of genetic and environmental factors such as parity, sex ratio, fraternity size, sire, year of farrowing and season of birth on the age at the first farrowing in gilts. The data were obtained from 400 litters of Duroc, Hampshire, Landrace, and Yorkshire raised at the Swine Breed-ing Station, National Livestock Cooperatives Federation from 1982 to 198. The results obtained are summarized as follows; 1) Effects of breed, sex ration and fraternity size on the age at the first farrowing in gilts showed no significant difference. 2) Effect of the sire on the age at first farrowing showed significant difference in Duroc(p<0.01) and York-shire (p <0.05) by about 3 months on the average between sires. 3) The effect of season on the age at first farrowing in gilts showed significant difference only in Landrace(P<0.01) being shortest(12.5±2.12 months) in the fall born gilts and longest(13.9±2.69 months) in the spring horns. The similar tendency occured also in other breeds studied, though no significant difference in the age at the first farrowing was found. 4) There were trends that as the fraternity sizes were greater at 8~9 in Hampshire and 9~ 11 in Yorkshire, the gilts farrowed first at younger ages. And for the greater fraternity sizes the gilts exhibited older ages at the first farrowing(p <0.05) . 5) The first farrowing ages were getting younger up to the 7th parity in Landrace and Yorkshire(P < 0.01).
