연중 매초급여(埋草給與)와 볏짚 및 건초혼합 급여가 우유생산에 미치는 영향
김준식,고문석,김길수,오대균 한국낙농학회 1983 韓國酪農學會誌 Vol.5 No.1
The effect of cornsilage and ricestraw, cornsilage and hay, cornsilage on milk yield, milk fat, live weight and economic analysis were studied by ad libitum experimental design. Four difference treatments were tested with the following experimental rouhage per day in forage basis: corn silage + rice-straw (25㎏ + 5㎏), corn silage + hay (25㎏ + 3㎏), corn silage + hay (20㎏ + 2㎏), corn silage (30㎏). Thereon, concentrate was fed according to milk production during the experimental period. The results obtained are as follows: 1. Dry matter intake per day during the experimental period among four treatments showed little difference. 2. The animal in treatment T2 tended to give higher milk yield than those in treatment C. T1, T3, but the difference was not significant statistically. 3. The cows in treatment T3 gave milk of higher fat content than those in treatment C, T1 or T2, but the difference was not significant statistically. 4. Treatment T1 gave the most increase in body weight following by treatment T2, C, and Treatment T3 gave the least increase in body weight during the experimental period but the difference was not signifficant. 5. Treatment T1 gave the most income in economic analysis followed by treatment T1, T3, and treatment C gave the least income in economic analysis during the experimental period.

직접적응제어방식을 이용한 직류전동기의 정밀 속도제어 시스템의 구현
김준식,정동근,홍철호,이택정,Kim, Jun-Sik,Chong, Dong-Keun,Hong Chol-Ho,Yi Taek-Jong 대한전자공학회 1989 전자공학회논문지 Vol. No.
In this paper, a precisely speed-controlled DC servo motor system utilizing direct adaptive control (DAC) algorithm which require that neither satisfaction of the perfect model following conditions (PMFC) nor explicit parameter identification is proposed. Computer simulation as well as experiments using MC-68000 are implemened with the above input trajectory fairly well in spite of load disturbances and parameter variations. Presented algorithm is simple and effective both in software and hardware applications. 본 논문에서는 모델과 플랜트의 완전 모델 추종 제어 조건이나 명확한 매개변수 추정자를 필요로 하지않는 직접적응제어방식을 이용한 직류전동기의 정밀속도 제어장치가 제안되었다. MC-68000 microcomputor를 이용한 실제적 시스템뿐만 아니라 컴퓨터 시뮬레이션 역시 이산적인 직접적응제어 알고리듬으로 구성되었으며, 전동기의 출력이 부하에 의한 외란과 매개변수의 변동에서도 기준 입력을 잘 추동함을 알 수 있었다. 적용된 알고리듬은 소프트웨어와 하드웨어적으로 모두 간단하며 효과적인 특성을 가지고 있다.

옥수수대 ( 藁稈 ) 및 자루 ( 穀實危含 ) 펠렛급여가 젖소 발육에 미치는 영향
김준식,김영근,오대균,지설하,최윤재,한인규 ( J . S . Kim,Y . K . Kim,D . K . Oh,S . H . Chee,Y . J . Choi,I . K . Han ) 한국축산학회 1985 한국축산학회지 Vol.27 No.2
A feeding trial with 20 heads of Holstein heifers was conducted for 90 days to investigate the feeding value of whole corn crop and corn ear with husk pellets. Four treatments were control, T₁ (corn ear pellet), T₂ (whole corn crop pellet) and T₃ (rice straw pellet). The results are summarized as follows. 1. Feeding corn ear pellet or whole corn crop pellet improved (p$lt;0.01) weight gain of dairy heifers with no significant differences between whole corn crop pellet and corn ear pellet, or between rice straw and control group. 2. Feed intake of experimental animals was higher in the order of T₁, T₂, T₃ and control group. However, the trend was not conclusive. 3. Feed cost per kilogram weight gain when expressed percent of control was 95.3, 94.6 and 11.1 for T₁, T₂ and T₃ group, respectively, indicating that feeding corn crop pellets was more economical for weight gain. Results from a present experiment show the feasiability of using whole corn crop pellet and corm ear pellet as a good feedstuff for ruminants.

本硏究의 目的은 經濟性 評價를 위한 原價比較法을 適用하고 이에 관련된 原價比較項目을 基礎로 하여 製品單位當 原價計算方法과 單位時間當 原價計算方法을 導出하려는데 있다. This paper has attempted to apply a method of minimum cost rule on the economic evaluation and to suggest another method of calculating the cost of unit per hour and unit per product respectively on the base of the comparative items of the cost related to the minimum cost rule.
