For the purpose of finding out the most desirable time for circulation exercise, this study has been done with the subject of 20 Kyung-Min Girls' Middle School students through Mar. 7, 1979 to Apr. 20. 20 students devided into two groups and one group practiced the circulation exercises between main exercises and adjustment exercise and the other group practiced circulation exercises between warming-up exercise and main exercise. The results of this study from the two groups practied circulation exercises are as the same as follows. 1) Return Running was 0.2 second developed by the group practiced circulation exercises between main exercise and adjustment exercise but there was no change by the group practiced circulation exercises between warming-up exercise and main exercise. 2) Five Steps Jumping Up at One Position was 20 cm developed by the group practiced the circulation exercises between main exercise and adjustment exercise but no change was done by the group practiced the circulation exercises between warming-up exercise and main exercise. 3) Jumping Far from One Position was 5cm developed by the group practiced the circulation exercises between main exercise and adjustment exercise but 1 cm dropped by the group practiced circulation exercises between warming-up exercise and main exercise. 4) 50 M Running was 0.2 second developed by the group practied circulation exercises between main exercise and adjustment exercise and no change was done by the group practiced circulation exercises between warming-up exercise and main exercise. 5) Bending and Stretching of Arm was 12 times developed by the group practiced circulation exercise between main exercise and adjustment exercise and 6 times developed by the group practiced circulation exercise between warming-up exercise and main exercise, too. 6) Rising Upper Body was 15 times developed by the group practiced circulation exercises between main exercise and adjustment exercise and 8 times developed by the group practiced circulation exercises between warming-up exercise and main exercise. 7) 100 M Running was 3 seconds dropped by the group practiced circulation exercises between main exercise and adjustment exercise but 15.02 seconds developed by the group practiced circulation exercises between warming-up exercise and main exercise.

The purpose of this study is to investigate the degree of service satisfaction by demographic factors of baby sport club consumer group. In order to attain this goal, consumer group of baby sport club was devided, and stepwise multiple regression analysis was used for service factor and service satisfaction. The results of this study are here below. First, there were differences of service satisfaction with facility and program of baby sport club by the level of academic background. It was found that parents graduated highschool are satisfied with the program factor of baby sports club and the parents graduated over college are satisfied with the facility factor. Second, there were differences of service satisfaction with facility and program of baby sport club by working style. It was found that parents both working are satisfied with the program factor of baby sports club and the parents non-both working are satisfied with the facility and the program factor. Third, there were differences of service satisfaction with facility and program of baby sport club by income level. It was found that low-income parents are satisfied with the facility factor of baby sports club and the hign-income parents are satisfied with the program factor.

IPS-empress system is one of widely used all ceramic system. The purpose of this study was to determine the pressing accuracy of reused IPS%Empress ingot. 10 specimens were made using new ingot first, and using the rests of the specimen the another group of specimens were made next. finally, the third group of specimens were made with same procedure mentioned above. The results obtained in this study were as follows ; 1. The pressing accuracy of the first group of specimen was 96.1%, that of the second group was 95.4%, and that of the third group was 95.4%. There was no statistical significance among them, that is, the reuse of the IPS-Empress ingot did not influence on the pressing accuracy. 2. the common site of the defect in pressed ingot was central area at the margin opposite of sprue hole.
IP/Ethernet 상에서의 DMTP 구현 및 성능 평가
송병권 서경대학교 산업기술연구소 1998 産業技術硏究所論文集 Vol.4 No.-
This paper introduces the implementation and performance evaluation of the Distributed Multemedia Transport Protocol(DMTP). The DMTP is implemented on IP/Ethernet of SUN Sparc20 with C-language in user space. Peformance evaluation of the DMTP is performed in a single LAN with 6SUN Sparc20, and the evaluation is done using the variation of parameters in real world. Performance evaluation of DMTP consists of two part; one is to find out the optimal values of rate control parameters, flow control parameter sand data packet size that affect transfer conditions in DMTP itself, and the other Is the comparison of the DMTP with TCP by these optimal values. This comparison presents the effciency of the DMTP over TCP that is a widely used transport protocol.

TETRA(Terrestrial Trunked Radio) is the standard of Digital Trunked Radio System developed by the ETSI(European Telecommunications Standards Institute). Currently, TETRA has been selected as Electric Power IT Wireless Backbone Network. Traditional distribution automation system has used the wireless network of Mobile Service Provider using CDMA(Code-Division Multiple Access) and WCDMA(Wideband CDMA) modem. Therefore, the development of gateway platform is indispensable according to the change to TETRA network. In this paper, we propose an embedded Linux-based platform for transmitting Industrial Electric Power IT protocol using TETRA network.

The SCADA(Supervisory Control And Data Acquisition) system is used the condition of the system which is in the remote area with the use which acquires a watch control and a data. Currently the SCADA system is used from the industry which relates in Water Power and Electronic Power. The communication protocol of the system for it is used in the SCADA system the DNP3.0, IEC-61850, DLMS comes to be representative used. This paper is analysis about DNP3.0, generate DNP3.0 Message, and then DNP3.0 call generator.
