In this paper, the pole placement design theory is applied to position control system of DC servo motor. The DC servo motor is modelled by second order linear time invariant system. We assume that All state variables are measurable and are available for feedback. If the system considered is completely state controllable, then poles of the close-loop system may be placed at any desired locations by means of state feedback through an appropriate state feedback gain matrix K. This design method called the pole placement. Proposed pole placement design has superior performance in unit step response. The pole placement design theory is very useful to drive the position control system of DC servo motor.

This study was experimented on the effects of time and concentration of the first and second applieation of 4CPA and GA3 on the berry set, seedlessness and quality of cluster in Kyoho grape. The results were as follows; In ratio of normal berry, seedlessness, weight of cluster, ratio of berry cracking and berry abscission after harvest in 25 treatments of the first and second different treatment stages with 4CPA (15ppm) and GA3(25ppm) alone and in combination, two treatments of mixed plot with 4CPA and GA3 in combination at fullbloom and 5 days before fullbloom at first and with GA3(25ppm) alone at 10 and 20 days after fullbloom at second were the most effective. and two treatments of GA3 plot applied with GA3(50ppm) alone 5 days before fullbloom at first and with GA3(25.50ppm) alone 10 days after fullbloom at second were effective in decreasing order. And then two treatments of 4CPA plot with 4CPA(15ppm) alone at fullbloom at first and with GA(25ppm) alone at 10 and 20 days after were also effective. In ratio of normal berry and quality in 29 treatments of different concentrations with 4CPA and GA3 alone and in combination, the plot treated with GA3 100ppm at fullbloom was the most effective, mixed (first; 4CPA(25ppm)+GA3(15ppm), second; Ga3(25ppm) and GA3 plot (first; GA3(25ppm), second; GA3(50ppm) and first; GA3(15ppm) second; fullbloom at second GA3(25ppm)) were shown as decreasing order. From above results, in high ratio of normal berry, increased weight of cluster and berry, seedless ratio, of berry cracking and mechanical berry absission after harvest, the plot treated with GA3 100ppm at fullbloom was the effective, and then the plot treated with 4CPA(15ppm) and GA3(25ppm), 4CPA(25ppm) and GA3(15ppm) in combination at fullboom or 5 days before fullbloom at first, and with GA3(25ppm) alone at 10 or 20 days after fullbloom at second were effective on seedless ratio, weight of cluster and normal too, but it is believed that this study must be continued because of shot berry formation and high mechanical berry abscission by berry cracking after harvest.

所得增大를 위한 포도 巨峰品種 栽培法의 實態調査 硏究 : 大邱市 近郊를 中心으로 at the commercial vineyards in the suburbs of Taegu city

金圭來 경북대학교 1989 새마을 硏究論叢 Vol.10 No.-

The auther investigated on the present status of cultural practices and faced problems of Kyoho grape cultivar at 10 vineyards near by Taegu city for reasonable cultural practices. The results were as follows. Tree age was 4-9 years and planting density was 42-240 vines per 10a. by vineyards. Dense planting problems didn't appear till now on, but thinning out will be needed in 1-2 years at the many vineyards. Generally, tree form was not planned before planting, present tree form is suitable in relation to planting distance therefore. At the 9 vineyards, tree form was terracing system with long shoot pruning while at the one vineyard with 4 years of tree age was Wakeman system with short shoot pruning, and the berry-set was good at all vineyards. Many of the vineyards were shown that number of berry per cluster and cropping load per vine was too much that maturation of berry was abnormal and berry cracking was serious. From this inverstigation, it is believed that terracing system with long shoot pruning is ideal for Kyoho cultivar and less than 50 vines per 10a are recommended for the permanent planting vines in case of self-rooted vines. And also it is considered that less than 40 berries per cluster and less than 2000kg of cropping load per 10 a is suitable for higher berry quality and earlier harvest before the early Septmber for the prevention of berry cracking.

This paper presents an adaptive self-tuning control algorithm of robot manipulator. To construct an adaptive controller under the assumption of independant joint dynamics, a linear discrete time-series model of autoregressive type with external exitations is chosen to represent the input-output measurements of each joint. This algorithm has been applied to three joint planar robot manipulator and trajectory tracking simulation has been conducted. The simulation results showed the effectiveness of designed self-tuning LQG controller can successfully be applied to control of robot manipulator.

The authors studied on the problems concerning to the establishment of vineyard at 25% slopped land with 50㎝ in soil depth. We investigated on the effects of manure, mulching, physiological disorder and personal expenditures for establishment of the vineyard. The results obtained can be summarized as follows; About thirty person per 10a were required for establishment of planting step. Growth of the vine was not different 50-100㎝ of soil depth from over 100㎝ of soil depth. About 30% of selected vine trees showed boron deficiency on the young leaves and flower cluster during early June and that 70% of the vine trees showed blackish berry caused by boron deficiency during early July. The vine mulched with straw, depth of 7㎝ and 15㎝, showed significantly larger shoot growth than that of control. 15kgr. of manure application per tree showed significant difference in growth than 5kgr.of manure, 5kgr. of hen maunre and control polt.

The aims of this study is to survey the achievements of the in-service training which was executed by the In-Service Teacher Training Institute of Chungnam National University during the summer vacation in 1984. After analyzing the responses to the questionnaire which were collectted from 435 technical teachers attending the in-service training, we reached following conclusions as suggestions. 1) It is desirable to establish a committee to decide the levels and contents of the major subjects under the in-service teacher training institute. 2) Lessening the numbers of major subjects and extending the hours of each subjects will make effective results on in-service technical teacher training. 3) It will be better to give a chance to teachers to take option in the major study field. 4) The Ministry of Education should make a plan to give a course on computer programming to technical teachers regularly.

Daminozide가 사과矮性台木 榮養生長 및 內生生長調節物質에 미치는 影響

崔誠容,金圭來 COLLEGE OF AGRICULTURE KYUNGPOOK NATIONAL UNIVERSI 1984 慶北大農學誌 Vol.2 No.-

This experiment was conducted to clarify the effect of daminozide on leaf area, shoot growth, and endogenous growth substances in dwarfing rootstocks of apple, M26 and MM106. The results were summarized as follows. When compared to control, leaf area and shoot growth were inhibited by daminozide treatments. The higher the concentration of daminozide, the more severe the inhibition of the leaf expansion and shoot growth in M26, whereas there was no significant difference among treatments in MM106. The emergence of lateral shoots and / or spurs was increased by daminozide treatments compared to control. The secondary growth was significantly promoted by daminozide treatment in M26, but not significantly in MM106. The diameter growth was no statistically different among treatments both in M26 and MM106. The higher the concentration of daminozide, the lower the activity of auxin-like substances up to the 34th day after treatment of daminozide, while higher the activity of inhibitor in both rootstocks. Two months later, the activity of auxin-like substances in 1,500ppm treatment was higher than that of control, but that in the concentration of more than 1,500ppm lower than control in M26 rootstocks. In contrast, the activities of inhibitor were not significantly different among treatments in the M26. In MM106 rootstocks, the activities of both auxin-like substances and inhibitor in daminozide treatments were higher than in control.

The study was carried out to evaluate toxicity of enrofloxacin and colistin complex (Enroco) with a dose of 10 ㎎/㎏/day, 20 ㎎/㎏/day and 40 ㎎/㎏/day via oral administration for 3 weeks in ICR mice. All procedures of the test were performed by the established regulation of Korean National Institute of Safety Research (1994. 4. 14). Appearance, behavior, mortality and food consumption of treated groups were not affected during the experimental periods. No significant does-related changes of the combined antibacterials were found in urinalysis, eye examination, hematology, serum chemistry, and organ weight. No histopathological lesions were observed in both control and treatment groups. Our results strongly suggested that no toxic changes were found in mice treated orally with enrofloxacin-colistin complex for 3 weeks.
