This study consists in clarifying the meaning of various angles and velocity, and two types of the stroke of a pushing shot and hitting shot through the three-dimensional image analyses among the factors of exercise. To attain the purpose of such studies, the result of experiment and analysis for each of three athletes of boys and girls in high school and three persons in general came to the conclusion as follows; 1. The last motion of a group of A having a command of a follow shot showed greatly, compared with two groups of B and C, and this showed that a group of A took a rectilinear motion greatly to gain power and two group of B and C took a rotary motion greatly to gain speed. 2. A group of A having a command of a pushing shot move body weight forward from behind and give the first consideration to a rectilinear motion, and two groups of B and C having a command of the stroke of hitting shot used the turning of the shoulder and the waist and gave much weight to a rotary motion than a rectilinear one. 3. The position of the hitting point of a group of A having a command of a pushing shot turned out to be the waist, and that of the hitting point of two groups of B and C, the chest, and namely this showed that the position of the hitting point was decided according to the form of the stroke and pictures of various kinds. 4. In impacting, the speed decreased, for the power was controled to keep an accurate timing of stroke just before impacting

Entomopathogenic fungi formulated as wettable powders and suspension concentrates have been sprayed to crop pests for pest management. However, the use of fungal granules to control paddy field pests has not been fully explored. Herein, several Beauveria bassiana isolates (ERL 1170, 1578 and 836) were produced as granules using a millet-based solid culture. The granules were applied to the rice nursery 3 days before transplanting and their control efficacy against rice water weevils was determined in paddy fields. The solid cultures produced ~1×108conidiag-1ofmilletgrains10daysaftertheinoculation. The granules were applied to the soil in the rice nursery 3 days before the rice seedlings were transplanted in the paddy fields. Rice in plots with granules of ERL1578 had 17.3% leaf damage (74% control efficacy) 14 days post application, whereas rice plants in the non-treated control had 66.5% damage. Rice plants treated in the nursery with ERL1170 and ERL836 had 52~54% damage. In the rice plots previously treated with ERL1578 the smallest numbers of larvae and adults were observed 38 days post application. In laboratory conditions, ERL1578-treated larvae were tuned pink and covered with mycelial mass. Applications of millet-based B. bassiana granules on rice nursery soil can be an effective and efficient biological control strategy for the management of rice water weevils. This method is relatively inexpensive and requires less labor compared to practices involving the spraying of fungi directly on rice in paddy fields.

The results of studied of the sports for all activity and juvenile are as follows : 1. It is expected for sports for all activity to make a great contribution to actualize the self by seeking the promotion of sports ability with balanced development of juvenile body. 2. It helps to from a desirable attitude and nature as well as to purify unsafety, conflict, violent behavior and accidental action through value and function of sports for all. 3. A sports for all activity is considered to offer the wider social experiences through voluntary participation with to be suitable for meeting desire of youngmen.

The result of survey and analysis by this study is following. 1. The shooters who are eager to make good records at the big event are likely to make poor record. So psycological fators are greatly affecting on the recore. 2. The whole record lagely depends on the first shot. 3. The excessive demand from the coach or the teacher is one of the causes to bring about a bad record. 4. The consciousness of an audience is mainly appeared on the poor record. 5. Equipments and facilities for shooting are make player feel little psychological instability, but feel greatly if it is windy unlike the normal weather.

본 연구에서는 개발사업 사례를 선정하여, 경관영향평가 프로세스와 세부 평가항목을 검토하고, 특히 평가항목 중 위락ㆍ경관요소 측면에 환경영향평가작성 등에 관한 규정에 명시되어 있는 프로세스를 따르고 있는지, 각 실제 개발사업에서 현황조사나 사업 시행으로 인한 영향예측, 저감방안 등이 합리적으로 실행되어지고 있는지의 여부를 판단하고 개선방안을 도출하고자 하였다. 본 연구는 자연환경이나 경관의 중요성에 대한 인식이 높아지는 것에 맞추어 환경영향평가에서 합리적 경관영향평가를 위해 3D Simulation을 활용하여 각 개발 분야의 특성을 고려하고 그에 맞는 합리적인 대안 제시에 기여할 수 있을 것으로 기대된다. In this study we had chosen the examples of the development projects, so that examined about the process of the landscape impact assessment and the detail evaluation items. Especially the part of the leisure facilities and the landscape aspects among the evaluation items were reviewed whether followed the process of environment impact assessment or not, whether the impact estimate, and depreciation scheme according to the present condition and enforcement of the actual development projects perform reasonably or not. From the study, derived the improvement on the landscape impact evaluation using with 3D Simulation method is expected to contribute to the valid landscape impact assessment and the reasonable alternative proposal.

Convergence between telecom and broadcasting is today a worldwide phenomenon. Diverse services like VoD, mobile broadcasting, IPTV and interactive services have already made their market debut or are currently being commercialized. Regulatory systems are also being revised to appropriately regulate this new breed of services. We propose the new model of educational broadcasting system using the internet network, it is not different conventional coaxial cable methods. Especially, we design the multicast method of the network using the limited channel and resource, propose the method of intercommunication in the school between the broadcasting system and database system.
