Support structures are used to support a component during building process and must be removed once the building is complete. For precise building this paper specified types of support structures by means of geometry characteristics. They are point, line and area. And found a new algorithm for detecting geometries which need support structures. For easy of removing support structure teeth profile generation and interferences avoidance algorithm was studied.

國民學校 Badminton 選手의 運動負荷 分析硏究

We came to the following conclusions that are drawn from the evidences collected form 8 badminton athletes (4 males and 4 females), all of whom attend primary schools in the city of Chun cheon, Kangwondo. These evidences are informations that are gathered by measuring the intensity of play harden (time number of steps, play distance, play Velocity, pulse of heart. maximum oxygeon absorption, efficiency of heart, calorie consumption, and weight loss) occasioned by the basic strokes and single matches. 1. In the basic strokes, Clear and Smash are shown to exert a very high level of intensity. While Drop, Hair Pin, and Drive are shown to require a averahe level of intensity. 2. Pulse of heart is a very useful measure of the intensity of play burden. This is evidenced by the fact that the game requiring strong pulse of heart also requires high level of intensity in maximum oxygeon absorption and calorie consumptions. 3. According to the game results, during the same time period, winners are shown to take smaller number of steps and to move shorter distances compared to the losers. 4. The game of badminton is likely to cause a vert high level of intensity of play burden to primary school students whether they are male or not.

This study was conducted to investigate the relationship between the takeoff style and flight distance in the running long jump takeoff motion. Eight male athletes who achieved at least the 3rd place in the long jump at the Korea National Track and Field meetings during 1994 and 1995 were selected as subjects. The long jump motions performed by the subjects were recorded using two 16mm high speed cameras at the nominal speed of 100 frames per second. The Direct Linear Transformation technique was adopted from the beginning of filming to the final stage of data extraction. It was found that: The mean takeoff velocity of the subjects at the instant of takeoff was 7.911±0.245m/s, the regrssion equation of flight distance(Y) predition was Y = 0.6960·(takeoff velocity) + 1.3091(r = 0.72, p<0.0000). And the mean height of takeoff of the center of gravity at the instant of takeoff was 1.088±0.048m which is equivalent to 60.34±1.78% of the mean height of the subjects, the regression equation of flight distance(Y) predition was Y = 8.1986·(height of C.O.G) + 1.8684(r = 0.62, p<0.0002). The mean takeoff angle at the instant of takeoff was 21.50±2.60°. Within the limitations of this study it is concluded: In order to increase fight distance, several conditions must be fullfilled at the instant of takeoff leg touchdown and takeoff during takeoff phase. First, the takeoff velocity should be fast at the instant of takeoff leg touchdown and takeoff. Second, the body C.O.G(Center of Gravity) height should be raised at the instant of takeoff leg touchdown and takeoff. Third, within the limitations of this study(the takeoff velocity of the subjects at the instant of takeoff was 7.911±0.245m/s), the takeoff angle at the instant of takeoff should be keep about 21.50±2.60°

The rhizomes of the Acorus gramineus Soland. have been used as analgesics, sedatives, stomachics and anthelmintics in chinese medicine. It is known that the rhizomes of the Acorus gramineus Soland. contains the essential oil about 0.5-0.8% and this essential oil contains Asarone about 86%. The Asarone possess many pharmacological properties similar to those of reserpine and chlorpromazine. Present paper, some pharmacological actions of the essential oil of the Acorus gramineus Soland. are observed. The results are as follows; 1) The essential oil of Acorus gramineus Soland. increased the sleeping time of the chicken anesthetized with hexobarbital sodium. 2) The essential oil of Acorus gramineus Soland. decreased the spontaneous activity of the chicken and the mouse. 3) The essential oil Acorus gramineus Soland. markedly inhibited the motility of the earth worm and the leech. 4) The essential oil of Acorus gramineus Soland. Showed the mydriatic actions on the isolated frog's eye ball.

This study was undertaken in order to examine parasiticidal action of the crude drugs to Eurytrema pancreaticum. For this purpose, Eurytrema pancreaticum was incubated at 37℃ in Hedon-Fleig solution which serial dilution of crude powder, water extact and alcohol extract were added respectively and motility of these organism was checked repeatedly untill cessation of movement was ascertained. The results are as follows. 1. Among 22 crude drugs, Acorus gramineus, Lindera strychnifolia, Inula Helenium Dryopteris crassirhizoma and Sophora angustifolia showed marked parasiticidal activity to Eurytrema pancreaticum. 2. In general, these drugs showed prominent parasiticidal actions in the form of alcohol extract, while less effective or no effective in form of water extract.

부화 전후에 있어서 병아리의 胃腺細胞에 關한 光學的 및 電子顯微鏡的 硏究

In the mammals, among others, there are two distinct cellular populations (or types) in the gastric glands, which are responsible for the secretion of acid and pepsin respectively; the parietal or oxyntic cells for acid secretion and the chief or peptic cells for pepsin secretion. On the other hand, the bird does not have separate parietal and chief cells in the glandular stomach, and there exists only a single cell type which secrets both of pepsinogen and acid. Precent study was conducted to know the morphologic changes of the these secretory cells in the proventricular glands during the development of chicken from its embryonal stage, by the light and electron microscopes. The results obtained were summarized as follow: 1. The first appearances of pepsinogen granules in the gland cells of the proventriculi were at 10 hours after hatching by the light microscope, while it was recognized at the 20th incubation day by the electron microspcope. These pepsinogen were gradually increased and reached to the adult chicken level at 96 hours after hatching. 2. The cell organelles were progressively developed (or enriched) during the incubation period, and the smooth and rough surfaced endoplasmic reticulum were further developed and more marked in chicken than embryo. 3. Intracellular canal observed in the mammals was not noted. 4. At 24 hours after start of the feeding, the pepsinogen granules were entirely discharged after hatching and disappeared.
