The exchange of resin and color were occured some troubles. These were decreased the products in the injection molding. The exchange of resin is established the flow of resin depending on the temperature. Some cases, the exchange od resin was desired another resins(so-call intermediated resin), which is non-reactive resin usually polyolefins. The exchange of resin and color was affected the surface of the screw, an angle and a distance of the clinder head between the screw head, and the shape of the nozzle.

양어장 폭기에 사용되는 AQUATEX 폭기장치의 효율성에 관한 기초적 실험연구

An advanced mobile technology is described to saturate the water with oxygen. The AQUATEX reactor is 2-10 times more effective in dissolving oxygen in water than many other systems used in aquaculture. because it can generate extremely small(0.005~0.05mm) bubbles. Because of the high mass transfer and very small bubble size the oxygen utilization by fish in our tests was 95 percent.

The purpose of this study was to identify effects of summary KP in person with MR on golf putting learning. Total thirty subjects who were in special class at high school participated in the study. The number of summary KP was divided into three types; 3,6,9 times. In experiment 1 subject had an acquisition session for 6 blocks of 9 trials; total 54 trials. Subjects who were in experiment 2 had 3 days acquisition session for 6 blocks of 9 trials (total 162 trials). Results were as followes: First, there were significantly difference in putting task according to types of summary KP. Second, results indicated that many summary KP was more effective in golf putting retention test of person with MR. Third, many summary KP was more effective in golf putting transfer test of person with MR.

Gastrodia elata (GE) is a oriental medicinal herb which has been used traditionally for the treatment of various brain diseases including convulsion and epilepsy. In order to examine the mechanism of anticonvulsive effect, we treated the methanol extract of GE (500 mg/kg, P.O) to the pentylenetetrazole (PTZ)-induced convulsive rats. Methanol extracts of GE siginificantly inhibited (35%) the convulsion state as well as the level of lipid peroxidation (25%) in the brain. The ether fraction of methanol extracts among the others effectively inhibited in vitro lipid peroxidation dose dependently (5.0×10^(-6)~2.0×10^(-5) g/ml). The scavenging effect on hydroxy radicals was found in all the fractions of ether, butanol, and dichloromethane. These results suggest that the anticonvulsive effect of GE is possibly due to the antioxidative effects of the active components in GE.

南部 畓地帶에서 發生하는 올챙이고랭이(Scirpus juncoides Roxb.)의 雜草生態的 硏究

許祥萬,金晋鎬,孫寶均 順天大學校 1984 論文集 Vol.3 No.1

This study on the occurrence, regeneration and reproduction of the problematic weed, Scirpus juncoides Roxb., in the paddy field in the southern area was carried on for 12 months in order to investigate the various adaptability. The results obtained are as follows: 1. In O₂condition, a slightly insufficient condition treated by 0.02mm polyethylene film was the most favorable for germination. 2. In temperature, the more favorable condition for the germination of S.juncoides Roxb. seed was 35℃, 30℃, 25℃ in order, and the emergence rate of their stumps was high from 20℃ to 30℃. 3. In light intensity, germinating rate of S.juncoides Roxb. seed was higher in shade conditions than in perfect exposure, and so was the emergence rate of stump. 4. In light quality, germinating rate of S.juncoides Roxb. seed was high in order of black, yellow, green, and colorless film, while the emergence rate of stump was high in green film treatment. 5. In hydrogen-ion concentration of soil, the most optimun pH value for germination was 5.7, while in the extemely acid and alkaline soil, the growth was checked after the sixth week. 6. The emergence rate of stump was high in order of 3g, 4g, 5g, 2g, 1g in stump weight. 7. Initial growth of S.juncoides Roxb. shoot at two weeks after its cutting depended on underground nutrition. 8. Regeneration vigour of S.juncoides Roxb. shoot became dull since a growth period, and only one cutting after 25, May was enough to control S.juncoides Roxb. 9. Cutting of S.juncoides Roxd. shoot in the lagvegetative period around the end of May did not affected its regrowth. 10. In soil moisture content, the number of flower-bud was more in 100% saturated condition than in 80% saturated. In the submergence condition, 2cm water flooded depth was the most favorable for flower-bud formation of S.juncoides Roxb. 11. There was no constant tendency in soil condition and poor aeration condition was well adapted to S.juncoides Roxb. 12. As the shade rate increased, the flower-bud formation of S.juncoides Roxb. was suppressed. 13. The flower-bud formation of S.juncoides Roxb. was increased in yellow polyethylene film treatment. 14. with the MPK fertilizer level increased, the number of flower-bud was rapidly increased.

In this paper, we implemented the hangeul tactile recognition system for the Blind. The system is consist of hardware part and software part.The hardware part is consist of a scanner interface image processing system, a electro tactile output device inter and auser interface. The software system consist of pattern learning routine,image processing and character pattern output routine, file management and operation window routine. The 16 by 16 of return electrode is driven by a electro-tacttile device. The recognition experimention distinguished learning beforefrom learning after,after learning the recognition rate is higher than learning before. As a results of experimentation before and after learning,the later is superior to the former. Therefore,if learning is increased, we can take higher recognition rate.

Presented in this paper is a new fast and robust algorithm generating NC tool path for 2D pockets with islands. The input shapes are composed of line segments and circular arcs. The algorithm has two steps: creation of successive offset loops and linking the loops to tool path. A modified pair-wise technique is developed in order to speed up and stabilize the offset process, and the linking algorithm is focused on minimizing tool retractions and preventing thin-wall cutting. The proposed algorithm has been implemented in C++ and some illustrative examples are presented to show the practical strength of the algorithm.

목표 지향적 양수 협응 동작의 운동학적, 신경생리학적 전략

허진영 한국스포츠심리학회 2003 한국스포츠심리학회지 Vol.14 No.2

이 연구의 목적은 목표 지향적 양수 협응동작 수행시 나타나는 연계 변화에 기저가 되는 협응구조 메커니즘을 행동학적, 운동학적, 그리고 근 신경생리학적 측면에서 규명하고 아울러 연령이 증가하면서 이를 메커니즘이 어떻게 변화되는지를 살펴보는데 연구의 목적이 있다. 3개의 연령집단(초등, 대학생, 노인) 총 15명이 한손 조준과제와 두 손 조준과제를 각 4번씩 수행하였다. 각 과제가 실시되는 동안 동작 분석기(Ariel Dynamics 2000)와 EMG(Mega, 1998)시스템이 작동되어 동작에 대한 자료가 저장되었다. 실험 결과 목표 지향적 두 손 동작의 연계가 모든 연령에서 나타났으며 두 손의 연계성이 마치 하나의 단위와 같이 나타났으나 동작 시간과 관련되는 근 신경생리학적?운동학적 변수는 연령에 따라 다소 다르게 관여하는 것으로 나타났다. 즉 대학생은 아동과 노인 집단에 비해 최소한의 신경생리학적 변수(길항근 지속시간)와 운동학적 변수(최소한의 각 위치, 효율적 거리-카버링)를 사용하여 목표조준 운동에 대한 두 손의 협응과 연계를 유지하는 것으로 나타났다. 아울러 노인과 아동은 대학생에 비해 속도-정확성 상쇄의 이점을 충분히 활용하지 못하는 것으로 나타났다. 기타 사항들이 논의되었다. This research examined behavioral(i.e movement time), neuromuscular(EMG) and Kinematic(3D analysis) characteristics of unilateral and bilateral aiming movements of three different age group. Three age group(10, 25, 68 years old; N=15) completed four unimanual aiming and four bimanual aiming movement tasks. While subjects performing the tasks behavioral, neuromuscular, Kinematical variables were recorded using Mega(1998) and Arieal Dynamics(2000)systems. Results indicatee that coupling of the two hands in symmetrical and asymmetrical aiming movements was present across the age. However, the linkage of the two hands was achieved in different ways for the three groups. For young adults the linkage of the two hands was accomplished by using minimum neuromuscular(duration of antagonist) and kinematic(angle between wrist and finger, effective distance-covering) variables. Both children and old adults group did not use effect of speed-accuracy for the coupling of two hands compare to the young adults group. More results were discussed.
