  • Interests in the field of rapid methods and automation in microbiology have been growing steadily on an international scale in recent years. International meetings concerned this problem have been held in elsewhere in the world countries since the past twenty years. But, unfortunately in the field of microbial examination in food hygiene, this problem have not yet been developed so much as in the field of clinical microbiology. Today, I would like to introduce you here present aspects of rapid and automation technologies, those which are manly carrying in milk and meats industries. My illustration will be given recent improved technologies using automatic apparatus and instruments along with process of microbial count procedure. Recent direct microbiological counting system (ChemeScan \ulcorner) as real time ultrasensitive analysis created by Cheminex Ltd., France is now most evolutional instrument to provide direct microbial counts, down to one cell, within 30 minutes. The results from these evaluations how a good correlation between the ChemScan system and the standard plate count method. This system will be successful application for not only in the field of pharmacology but also food microbiology. In addition, current identification of microbes by sophisticated instruments suitable for food microbiology, one of which Biology is manual system (BIOLOG\ulcorner), provides reference-level capability at a modes price. For the manual system, the color reactions in the microplate are read by eye and manually keyed into personal computer. Species identification appears on the computer screen within seconds, along with biotype patterns, a list of closely related species, and other useful statistics. In present this is useful application for microbial ecology and epidemiological survey. RiboPrinter system newly produced by DuPont is now focusing among microbiologists in the world, and is one of the biggest microbial characterization system using a DNA-based approach. The technology analyzer is bacterial culture for its genetic fingerprint or riboprint pattern. Finally Bio-cellTracer system for automatic measurement of fungal growth and Fukitori-Maseter, a Surface Hygiene Monitoring Kit by using swabe procedure in food processing environment are briefly illustrated in this presentation.

  • The practical applications of piezoelectric ceramics are applied not only under low electric field environment. Therefore, an examination for characteristics of PZT ceramics under the high electric field condition can contribute to reducing the susceptibility of multifarious applications and to facilitating production of control circuits. These contributions can lead to the expansion of industrial applications. In this research, we fabricated disk-type PZT ceramic samples using conventional methods, measured the resonance characteristics of these samples under from low to high voltage conditions and calculated the PZT constants.

  • In this study, we conducted a survey to examine the runoff characteristics of nonpoint sources, which wash off pollutants from the surface of basin during rainfall and affect water pollution of streams. An Anyangchun basin in the region Ewiwang City was selected as a study site. The basin divided into several subbasins such as Wanggokchun, Ojeonchun, and Anyangchun based on the tributaries, which confluence to the main stream of Anyangchun. Four times of field examination had been carried out between July and August of 2000, and water quality data collected from the surveys had been analysed. The survey includes in-situ flow, DO and PH measurements in the outlet of catchment. Laboratory analysis includes BOD, TN, TP. From the result, pollutant by runoff of nonpoint sources were washed out along with stormwater in the beginning of rainfall, and flowed into streams resulted in stream pollution. In case of BOD, the load from Ojeonchun catchment, most of which included urban areas, took up 50% of the total load from the entire watershed. Thus, by the results, it is clear that runoff load by urban nonpoint sources plays an important role in the control and management of nonpoint sources for the watershed.

  • The pathogenicity of Br abortus RB51 strains, producted by commercial vaccine companies in Republic of Korea and USA, were evaluated in mouse and guinea pig. BALB/c and ICR mice were intraperitoneally inoculated with RB51 vaccines or virulent field strain and the existence of RB51 including its ratio of spleen to weights and persistence in spleens were examined. Groups of guinea pigs on day 55-58 of received subcutaneously with various RB51 vaccines, RB51 field isolates (Daehungjin) or virulent field isolates(Sangju) to compare the histopathogenicity in uterus. All the mice received RB51 vaccines or RB51 field isolates survived for 10 days, but the groups of mice received virulent field isolates died 5 from 11 (45.5%) in case of BALB/c mice and 12 from 12 (100%) in ICR mice, respectively. The number of RB51 in the groups of mice given with vaccine strains and RB51 field isolates were declined rapidly were in spleens between 12 and 20 days after inoculation. In contrast the mice given with the virulent field isolates rose in number of bacteria up to 20 days after inoculation. In the groups of mice infected with virulent field isolates, the ratio of spleen weights to body weight were significantly higher than those in control or in the groups inoculated with RB51 strain, including RB51 field isolates, at 12 and 20 days after inoculation. At ten days after inoculation, placentas of both the pregnant and non-pregnant guinea pigs were conducted for histopathological examination. Although any abnormal lesions were not observed in non-pregnant guinea pigs, all the strains caused the inflammation of the placenta, implying pathogenecity of RB51 in pregnant guinea pigs.

  • 진단 X선 촬영에 의한 소아 및 성인의 장기 등가선량과 유효선량을 구하는 방법론을 개발하였다. 연령에 따른 체격의 차이가 방사선량 분포에 미치는 영향을 평가하기 위해, 식도를 포함한 4개 연령군의 MIRD형 수학적 모의피폭체를 제작하였다. 두 가지의 전형적인 진단 X선 절차인 흉부 PA와 복부 AP 진단 X선 촬영을 모사하여, 연령별 선량을 계산하였다. 흉부 PA 진단 X선 촬영절차에 의해서 환자들은 대략 0.03mSv의 유효선량을 피폭하는 것으로 나타났다. 복부 AP 진단 X선 촬영절차의 경우 연령에 따라서 0.4에서 1.7mSv의 유효선량을 받는 것으로 나타났다. 한정된 조사장을 갖는 방사선에 대해서 선량을 평가했기 때문에, 장기의 위치와 크기, 모양, 그리고 방사선이 입사하는 표면으로부터의 필이 등이 선량 계산에 상당한 영향을 미쳤다. 따라서 진단 X선의 조사장이나 선질의 조절 등을 통해 방호의 최적화를 위한 노력이 중요한 것으로 나타났다. 본 연구에서 개발된 선량계측 절차는 의료방사선 방호의 최적화를 위한 수단으로 활용될 수 있다.

  • 인터넷이 교육분야에도 활발히 사용되면서 자료검색부터 동영상 강의 나아가 인터넷을 통해 실시간으로 시험을 치르고 있다. 웹을 이용한 원격시험에 출제되는 문제들은 대부분 고정출제나 문제은행방식을 이용한 무작위 출제방식을 사용하고 있다. 본 논문의 문제은행시스템은 마크업 언어를 모르더라도 문제를 제작할 수 있으며, 웹 상에서 시험을 치르고난 후 정답률에 기초하여 난이도를 자동으로 재조정할 수 있다. 또한 학습자는 시험이 끝난뒤 피드백 학습을 할 수 있으며, 학습 후에는 학습자가 스스로 난이도를 조정하여 재시험을 치를 수 있게 하였다. 자동난이도 출제 방식은 출제가 간편해지며 평가의 예상평균점수를 미리 예측하고 시험결과가 계속 문항마다 누적되어 이를 바탕으로 출제되는 문제가 너무 쉽게 또는 너무 어렵게 출제되는 것을 막을 수 있다. 또한 원격시험은 대리시험 등 부정의 소지가 많아 유형이 다른 문제를 출제하게 되는데 여기서 오는 형평성 문제를 극복할 수 있게 된다.
