The aerozolization is one of possible Brucella transmission mechanisms, particularly in air-borne exposed laboratory workers. In this study, seven laboratory workers were potentially exposed to B. abortus via aerosols. Two laboratory workers who sniffed an agar plate several times were considered to be at high risk for acquiring the disease, 5 workers who did not work directly with the strain were be considered at low risk of infection. Prophylactic antibiotics of doxycycline 200 mg/day and rifampin 600 mg/day were offered for 6 weeks in high risk workers and 3 weeks for low risk workers respectively. Enrolled workers were advised to check for serological testing of Brucella species every 3 weeks during a total period of 12 weeks. Compliance with taking medicine was 57.1% (4/7) and compliance for completing the serological tests was 85.7% (6/7). None of the laboratory workers developed clinical disease or tested positive serologically during 3 months of seroloaical testing and 1 year of clinical follow-up.

현재 의료진단, 화학공정의 모니터링이나 환경공학적 감시 및 제어 등의 분야에서 사용되고 있는 기존의 센서는 고가이며 용적이 클 뿐만 아니라 분석시간이 길고 사용하기 까다로운 것 등 여러 가지 문제점이 있다. 또한 측정환경에 영향을 주지 않을 만큼 충분히 작으며 빠른 분석시간을 가진 센서를 필요로 하고 있다. 본 연구에서는 기존의 센서들의 난점을 극복할 수 있는 새로운 형태의 FET형 전해질(electrolyte : H^+, K^+, Ca^2+, Na^+)분석 시스템, 용존가스(O_2, CO_2)분석 시스템의 개발을 중점적으로 추진하며, FET형 압력센서, 습도센서, 방사형 온도센서 등의 개별 FET형 센서에 관한 연구도 병행하고자 한다. Recently various kinds of sensors have been developed, being applicated to their own purpose. There are lots of difficulties to apply them to measurements in which the real-time monitoring is required without disturbing the surrounding environment. FET type semiconductor sensors, fabricated by the semiconductor integration technologies, have many advantages for their miniaturization, standardization, mass-production and in vivo/in situ monitoring. They also hold a very proper configuration for multi-functional sensors or integrated smart sensors, and wide availability by forming various kinds of physical or chemical sensing materials onto their sensing gates.

Ordinarily stow net fisheries was used by floater beam and sinker beam for the purpose of spreading the mouth of net. But it was not only iuconvenient and dangerous but much defective. In this thesis, we have studied fundermental experiment of the improved stow net fishing gear using head rope, ground rope and otter sail instead of floater beam and sinker beam. From the result of this experiment, it has been succeeded for fishing work to achieve basically without any difficulty. The results obtained in this study were as follows. 1) The resistance of fishing gear was estimated R≒7V2 as possible as it is taken greatly. (R: Resistance V: the rate of current) 2) The interval of otter sail was spreaded smoothly. Being in normal condition, it was maintamed the width 37-38m. It was heared comparison with net mouth of ordinary gear, and the shearing force was enough. 3) The height of mouth was lower than we have anticipated to and seemed to have the supplement of buoyancy. But according to increasing the rate of current, the lowness of mouth height was little affected. 4) The height of otter sail was decreased at the rate of 30% by the rate of current, on the contrary, the height of wing was not decreased owing to sufficient buoyancy, 5) The adjustment of extention length of hanging wire(connected with fishing boat) and raising wire(with otter sail) was great important problem and it must be dealed with the most moderatly because of a corelation between the spreading of fishing gear and catching ability. 6) On the depth of 30m, it was taken 25 minuits to cast anchor and lines, 20 min cast net, 24 min haul net, 45 min haul lines and heave anchor, respectively. 7) The improved stow net with otter sail was cleared up the defects and difficult problems in ordinary gear using floater beam and sinker beam, and it have more advantages of fishing work than ordinary one. But there were involved in lots of problems in details to solve in the future.

Holography에 의한 Loudspeaker Cone의 振動에 관한 考察

李慶源,朴鍾允,林鍾洙,朴興秀 成均館大學校 科學技術硏究所 1984 論文集 Vol.35 No.1

Optical holographic interferometry is used to study the forced vibrational cone behaviour at some frequencies and photographs of resultant hologragm images are included. The entire cone vibrates almost uniformly in the low frequency region. Above certain frequency both transverse and longitudinal waves are coupled and together determine the vibration patterns. The coupling between longitudinal and bending waves gives rise to an antiresonance that the transverse amplitude become large. Bending waves only occur above the frequency at which this antiresonance occur. As the frequency increases, the resonance effect gradually progresses from the outer edge to the inner edge.
