Korean veterinary medicine is a member of a major health profession with its own system of education, licensing, organization, and ethics, and a pioneering profession in his or her scientific knowledge and skills for the benefit society through the promotion of animal health, the relief of suffering, the conservation of livestock resources, the promotion of public health, biomedical work for medicine including comparative medicine, and the advancement of medical knowledge. This manuscript is to emphasize the role of the Korean public health veterinarians preparing the twenty-first century in public health service for humans.

The epidemiology of reported food-borne disease (FBD) outbreaks from 2001 to 2008 in Korea and Japan were compared in this study. The outbreak rate of FBD in Japan was significantly higher although the average number of patient in each outbreak in Korea was much higher. In both countries, summer was the season when most FBD outbreaks occurred. The comparison study revealed that FBD outbreaks in spring were more frequent in Korea, and outbreaks in winter were more frequent in Japan. Almost half of FBD outbreaks were observed at restaurants in both countries while FBD outbreaks at schools and work-places in Korea were much higher than in Japan. The most frequent cause of bacterial FBDs in Korea was pathogenic Escherichia coli followed by Salmonella species. On the other hand, Campylobacter jejuni was the most frequent source of bacterial FBDs in Japan. Norovirus, which is related to uncontrolled hand hygiene and involvement of ill food workers, was the main cause of viral FBDs in both countries. In conclusion, there are common epidemiological characteristics as well as several differences in FBD outbreaks of Korea and Japan. These are suggested to be originated from the characteristic of climate, food sources, and life styles in two countries. Establishment of stricter control and surveillance system for FBD outbreaks are required for prevention and reduction of FBD outbreaks in both countries.

본 연구의 목적은 L. monooytogenes에 대한 LP system의 항균효과를 측정하기 위하여 수행되었다 초기 접종수준(10², 10⁴, 10^(7) CFU/ml), LP의 농도는(10, 20, 30 ppm), 그리고 저장온도(5, 10, 15℃), 배지종류(TSB-YE, UHT milk)에 따라 L. monocytogenes에 대한 항균효과를 측정 비교한 결과 초기접종수준을 10²cfu/ml로 하였을 때와 LP농도는 10 ppm 및 5℃로 배양에서 항균력이 높게 나타났다. UHT milk를 이용한 LP system의 항균효과는 Tryptic soy agar를 이용한 시험결과와 비슷하게 나타났다.

Underwater robotic vehicles(URVs) are used for various work assignments such as pipe-lining, inspection, data collection, drill support, hydrography mapping, construction, maintenance and repairing of undersea equipment, etc. As the use of such vehicles increases the development of vehicles having greater autonomy becomes highly desirable. The vehicle control system is one of the most critic vehicle subsystems to increase autonomy of the vehicle. The vehicle dynamics is nonlinear and time-varying. Hydrodynamic coefficients are often difficult to accurately estimate. It was also observed by experiments that the effect of electrically powered thruster dynamics on the vehicle become significant at low speed or stationkeeping. The conventional linear controller with fixed gains based on the simplified vehicle dynamics, such as PID, may not be able to handle these properties and result in poor performance. Therefore, it is desirable to have a control system with the capability of learning and adapting to the changes in the vehicle dynamics and operating parameters and providing desired performance. This paper presents an adaptive and learning control system which estimates a new set of parameters defined as combinations of unknown bounded constants of system parameter matrices, rather than system parameters. The control system is described with the proof of stability and the effect of unmodeled thruster dynamics on a single thruster vehicle system is also investigated.
