      • 우리나라 농촌주민에서 쭈쭈가무시병의 혈청역학적 연구

        오명돈,최강원 대한감염학회 1991 감염 Vol.23 No.1

        To estimate the prevalence of Tsutsugamushi disease, we tested sera from 312 residents (150 residents who live in Jawoon-ri, Nae-myon, Hongcheon-goon, Kangwon-do, 85 in Daeboo-do, Ongjin-goon, kyunggi-do, and 77 in Sagock-ri Chilsung-myon, Goesan-goon, Choongchungbook-do). These three villages are located in the remote rural area in the central part of Korea. L-929 cells were infected with Gilliam, Karp, Kato, and B119, a strain isolated from a Korean patient, respectively. After about 10 days L cells were harvested and pooled to make antigens which have three prototype (ie, Gilliam, Karp, Kato) and one local strain (B119). L cells were coated on 12 well slides and indirect fluorescent antibody test were performed with goat anti-human IgG and IgM antibodies. Ten (6.7%) out of 150 sera from Jawoon-ri, 4(4.7%) of 85 from Daeboo-do, and 3(3.9%) of 77 from Sagock-ri were reactive at 1:20 dilution to anti-IgG antibody. But no sera were reactive to anti-IgM antibody.

      • A Simple Method for the Detection and Identification of Korean Brown Cattle(Hanwoo) using DHPLC

        Kang. Won,Park. Sane-Bum,Nam. Youn-Hyoung,An. Young-Chang,Lee. Sang-Hyun,Park. Jin-Keun,Lee. Jae-Sik,Jang. On-Cheoul,Park. Su-Min,Park. Yong-Hyun,Ko. Kyung-Hee,Moon. Sung-Sil 한국축산식품학회 2006 심포지움 및 학술발표회 Vol.- No.37

        Denaturing high-performance liquid chromatography(DHPLC) is used in a wide variety of genetic applications and is an efficient method for detection of mutations involving one or a few nucleotides. We developed a high-throughput DHPLC method for identifying polymorphisms in the MC1R gene that are characteristic of Hanwoo cattle. We compared 10 tissue samples from Hanwoo cattle, 10 samples from Holstein cattle and 10 samples from Hanwoox Holstein crossbred cattle to determine whether DHPLC analysis can be used to distinguish between these genotypes. Samples obtained from Hanwoo cattle had a unique profile of peaks that could be used as a molecular fingerprint for this breed. We also analyzed two hundred samples in a trial in which we were blinded to the genotype of the samples and correctly identified the breed-of-origin of 594 out of 600 sequence variations(99%).

      • A DYNAMIC SIMULATION MODEL FOR THE EVALUATION OF TRAFFIC MANAGEMENT SCHEMES

        Kangwon Lim,Yongtaek Lim,Seungjae Lee 대한교통학회 1998 대한교통학회 기타자료 Vol.1998 No.-

        The potential new advanced technologies developed recently around world are to influence traffic movement and travel behaviour. In special, traffic information systems have become principal issues in many countries as a modem technology for alleviating traffic congestion in urban area. Traveler information is essential for the roadway system to operate efficiently and safely. In mainline control, traveler information systems advise motorists freeway conditions so that the driver can take appropriate action, thus enhancing the efficiency and safety of traffic operations. Traveler information allows the driver to make informed decisions and act accordingly: i.e., continue on a planned route or divert to an alternate to avoid delays. Traffic management schemes are the operation tools producing a consistent, efficient allocation of traffic resources such as traffic information, optimum signal control and traffic demand strategies in order to avoid or reduce the urban congestion. This management schemes lead to make the best use of available road capacity. Management schemes also enable to reduce the time and resources needed to deal with traffic incidents, to respond automatically to changing traffic controls and conditions, and to avoid congestion areas.

      • Improvement of the Reaction Force Generation on UCC HIL System

        Kangwon Lee,Seungkyu Oh,Jinhee Jang,Hyungsoo Kim,Youngwoo Kim,Jinhuyn Ahn,Myungchul Jung,Jihoon Roh 한국자동차공학회 2008 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-

        Most electronic chassis control systems so far have been designed for optimization of its own performance. These are for the improvement of the vehicle dynamics performance including stability and ride comport. The Previous work, we developed an Unified Chassis Control HIL (Hardware-In-the-Loop Simulation) system including Electric Power Steering (EPS), Electronic Stability Control (ESC) and Continuous Damping Control (CDC) system. From the previous results, we could know that EPS system has a small control bandwidth for the lateral vehicle dynamics performance. And we recognize that the Steering Reaction Force is very important the driver to get information about the contact condition between the tires and road by human's sense. Therefore, this feeling should be generated by reaction force generating system of a UCC HIL. Reaction Force is generally simulated as rotation torque applied to the steering wheel. but in this study, the actual steering system is installed onto the HIL simulator, so the aim was to achieve the torque loaded on the tie rod (Rack Force). In this study, the VehSim vehicle model with the 27-degree of freedom is applied. VehSim vehicle model is build up by the real vehicle and tire data measurement and test. This Paper proposes the control strategy and the method of steering reaction force calculation and describes reaction force generating system of our UCC HIL.

With the complexity of bronze assemblages as a standard, from the period of the Weiyingzi type culture until the emergence of Warring States Yan culture the individual regions of the Liaoning area reached chiefdom level society as follows: the upper Dalinghe river sphere and Bohai bay coastal area sphere reached chiefdom level society during the 12th to the 10th century B.C., with the exception of parts of Liaodong, almost all the regional spheres of the Liaoxi area with the upper Dalinghe river sphere as the center reached chiefdom level society in the 8th century B.C., and during the 6th to the 4th century B.C., although there were differences in cultural level, a great part of Liaoning reached chiefdom level society. Beginning with the formation of complex societies, the individual regional spheres of the Liaoning area underwent social changes and several changes in mutual interaction spheres. The first occurred during the 12th to the 10th centuries B.C. by the Weiyingzi culture centered in Kezuo prefecture, the second occurred in the 8th century B.C. led by the Shiertaiyingzi culture of the middle reaches of the Dalinghe river sphere, the third occurred during the 6th to the 4th century B.C. with the Nandonggou and Zhengjiawozi types of the Shiertaiyingzi culture, the fourth occurred in the 3rd century B.C. with the Warring States Yan culture of parts of the Liaoning area. The many cultural and social changes which occurred in the Liaoning area in later periods became more intense and drastic in nature. The mutual interaction sphere formed by the Nandonggou and Zhengjiawozi cultures within and without the Liaoning area caused the indigenous cultures of individual regional spheres to be transformed into cultures of higher cultural levels. Also the transplantation of Warring States Yan culture in the 3rd century B.C. had a large influence on the changes in cultural topography and social changes in parts of the Liaoning area.
