線型 model의 母數의 推定, 變數의 選擇問題 等에 있어서 여러가지 새로운 基準과 方法들이 提示되어지고 있다. 그 中 한 方法으로서 Hawkins와 Webster등이 相關行列의 正準分析에 衣한 여러가지 表現式을 誘導하고 幾何學的인 또는 漸近的인 性質들을 誘導하였다. 本論文에서는 相關行列뿐만 아니라 積行列에 關하여서도 Rohde의 定理를 써서 直接 여러가지 表現式을 얻었으며 나아가서 Marquardt의 理論과 方法을 遠用하여 generailged inverse 推定値을 誘導하였다.

This experiment was conducted in effort to determine safety and proper amount of Urea, Coating urea and Diuredo-isobuane (DUIB) in Korean Native Goats. The results obtained were as follows: 1. Ruminal pH values were considerably higher (7.0-8.0) on area and coating area treated goats. But constant ruminal pH values were recorded on DUIB treated goats. 2. Ruminal ammonium nitrogen concentration were below toxic levels when treated with coating urea (0.77 gm/kg B.W.) and DUIB (1.28 gm/kg B.W.). Although urea (0.3 gm/kg B.W.) were slightly above toxic levels. 3. Blood ammonium nitrogen concentration were below toxic levels when treated with urea (0.3 gm/kg B.W.) coating urea (0.77 gm/kg B.W.) and DUIB (1.28 gm/kg B.W.) 4. Korean Native Goats used were intoxicated by 0.9 gm urea per kg B.W. and 2.33 gm coating urea per kg B.W. between 40 minutes and 80 minutes after administration. 5. Initial rise in ruminal pH and blood ammonium nitrogen concentration was a tendency for a decline after 4 weeks feeding urea (0.3 gm/kg B.W.) and coating urea (0.77 gm/kg B.W.) (p<0.05). The present data reveal that DUIB is most efficient NPN resource in Korean Native Goats.

In this report has experienced the Possibility and starting condition for composting of night soil and municipal refuse with a view of developing a reusable humus product. Hereby is found as followings; 1. The municipal nightsoil has C/N ratio about 4 and C=0.52GV (significance level 80% in winter season). The municipal nightsoil has to increase his C/N ratio and decrease his humidity for composting. 2. The municpal refuse in Busan has compostable matters about 20% in 1977 and has increased 2% per year as compared With 1972. 3. It is considered the best humidity for starting composting about 35% and warm development about 40-50%.
