SSB와 VHF 통신시스템에 대한 원격제어 연구

조학현 木浦海洋大學校 2002 論文集 Vol.10 No.2

해안국과 군대의 기지국에서는 기존의 SSB와 VHF 송수신기에 의한 무선통신은 아직도 매우 유효하게 사용하고 있다. SSB와 VHF의 장비는 해상과 육상에서 정보전달에 매우 중요하다. 해안국과 터미널간에 있어서 기존 SSB와 VHF 송수신기에 의한 통신상대는 1:1 방식이다. 그러나 이 1:1의 방식을 1대 다수로 한다. 그러면 주파수를 아낄 수 있고, 또 해상에서 조난, 긴급, 안전통신 및 군용통신에서 효과적으로 할 수 있다. 또 1대 다수방식은 인터럽트를 할 수 있다. 그것은 중요통신의 신속한 전송에 편리하다. 이 논문은 기존의 SSB나 VHF 통신장비에 ICS를 설치하였다. 이것은 하나의 단말기에서 여러 송수신장비와 통신을 할 수 있다. 이 장비를 VHF 통신에 설치하면 원거리에 있는 선박과 양호한 통신을 할 수 있다. 그러므로 이 방식은 통신범위를 넓힐 수 있다. ICS에 의한 회선교환 방법은 PPT 신호와 음성신호가 변조된 ASK로 원격조정을 한다. ICS는 회선교환기를 통하여 단말기와 송수신기의 접속을 수시로 변경할 수 있다. 이렇게 하기 위해서 ASK방식에 대한 정보전송, ICS의 시스템 개발. 제어 알고리즘의 구현, 멀티프로세서의 시스템 개발, 전송방식, 모니링을 연구하였다. 따라서 이 논문은 원격제어를 위한 무선통신장비의 희선교환 제어방식으로서 해상통신, 군용통신, 어업통신 등을 위한 무선국 통신장비의 개선에 기여도가 클 것으로 기대된다. The radio communications by SSB and VHF transceivers are still used very efficiently in coast stations and military base stations. The SSB and VHF equipments are very important to transmit and receive informations in the sea and the land. The communication system by the conventional SSB and VI-IF transceivers between a coast station and a terminal is an one-to-one system. In this dissertation, however, the conventional one-to-one system is expanded to one-to-multiple systems. Then, frequencies can be used effectively for distress, urgency, safety traffic, and military communications. In addition, one to multi-number systems can be used to interrupt, which is useful to transmit rapidly in the information traffic. An ICS has been proposed and added, in this dissertation, to the conventional SSB and VHF communication systems, which can realize one-to-several terminal communications. When the ICS equipments are set up to the VHF transceiver, It is possible to communicate with ship in far distance the communication range can be enlarged. The line switching system by the ICS is to be remote-controlled by ASK modulated PTT signals and audio signals. An ICS can change a connection between terminal and transceiver through a circuit switching system at any time. For this purpose, the author has researched and developed a ASK transmission system, ICS system, control algorithm, multiprocessor system, and monitoring system. As a conclusion, the developed line switching control systems and equipments can be used effectively for maritime communication, military communication, fishery communication, etc.

The purpose of this study was to analyze the microbiological hazards of dried fish (Jwieochae,0jingeochae and Bugeochae), and to apply pretreatment methods to increase the safety of cooked dried fish within foodservice establishments. Microbiological inspections were conducted on Total Plate Count, Coliforms, E. coli, E. coli 0157:H7, Staphylococcus aureus, Salmonella spp. and Listeria monocytogenes. The study results are summarized as follows. According to the Hazard analysis, there are many problems showing high numbers in terms of Total Plate Count and Coliforms, which were both well over acceptable standard levels. E. coli and Staphylococcus aureus were detected at certain foodservice establishments, while E. coli 0157:H7, Salmonella spp. and Listeria momocytogenes were not detected at all. By applying various Pretreatment methods, such as washing, blanching, panfrying and microwave heating, the levels of microbiological hazards were able to be controlled and lowered. Blanching was the most effective method, followed by panfrying, microwave heating and washing. The Total Plate Counts gradually decreased with increasing number of times washed and seconds panfried. From these results, it is concluded that to guarantee food safety, cooked dried fish raw materials should be kept hygienically and appropriate pretreatment methods applied before cooking.

The dentigerous cyst originates through alteration of the reduced enamel epithelium after amelogenesis is completed, with accumulation of fluid between the layers of the enamel epithelium or between this epithelium and the tooth crown. It is always associated with unerupted teeth. there are two methods of treatment which are generally accepted. One is the enucleation of the cystic sac in its entirety, the other is the Partch operation, or the marsupialization, by which the cyst is uncovered or 『deroofed』 and the cystic lining made continuous with the oral cavity or surrounding structures. We have 3 cases involving management of impacted & displaced teeth after marsupialization of a dentigerous cyst. We would like to summarize the results of the report as follows: The teeth which had been displaced near the bottom of mandible and dislocated distally or mesially by the pressure of the cyst on which had been displaced and inclined abnormally by the pressure of the cyst, have a tendency to erupt rapidly into their normal position soon after marsupialization, even without the application of orthodontic measures.
