This paper presents the analysis of the analysis of thrust characteristics of linear induction motors(LIMs) according to secondary reaction plate. LIMs are well known as high speed transport systems, which can obtain thrust directly without gears and links, or auxiliary mechanisms. A simple structure, easy maintenance, and less environmental pollution are advantages of LIMs. In transport systems using LIMs, the secondary reaction plate is an important design factor, because it has considerable impact on the cost of the railway as well as the performance of the LIMs. This paper deals analyzed the characteristics of linear induction motor used for moving the vehicle of container scanner. Thrust, efficiency and load characteristic were interpreted with FEM regarding two models whose material of secondary reaction plate was copper and aluminum. It suggested the interpretation of thrust, efficiency and power factor characteristic along slip and compared the operation ability of linear induction motor through characteristics analysis along the load.

본 연구는 치아우식증에 관련된 Mutans streptococci 표준균주 및 임상분리 균주의 성장억제를 유도할 수 있는 천연 생약추출물을 검색하기 위하여 실시되었다. 녹차추출물은 CHMC-2032를 사용하였으며, 결명자 추출물은 50% 에탄올을 이용하여 얻었다. 이들 추출물의 Mutans streptococci 표준균주 및 교정환자들에서 브라켓과 치면 사이의 경계부에서 분리된 각각 10 균주씩의 S. mutans 및 S. sobrinus에 대한 최소성장억제농도를 액체배지 희석법으로 구하였다. 그 결과 CHMC-2032의 S. mutans 및 S. sobrinus의 표준 균주, S. sobrinus의 대부분 임상분리 균주에 대한 최소성장억제농도는 5 mg/ml이었다. 그러나 결명자 추출물에 의한 S. mutans 및 S. sobrinus에 대한 세균 성장억제 효과는 미미하였다. 본 연구 결과 치아우식증의 예방적 측면에서 결명자차보다는 녹차를 마시는 것이 유리하며, CHMC-2032를 이용하여 구강양치용액을 제조하여 사용할 경우 교정환자를 포함하여 대부분의 사람에게서 치아우식증 예방 효과가 있으리고 추정된다. Mutans streptococci is the major causative factor in dental caries. Especially, orthodontic patients with fixed appliance are a risk group for dental caries. Because fixed appliances attached on teeth may change the environment of dental plaque, the enamel decalcification or dental caries around the bracket and band is a major side effect of orthodontic treatment. The aim of this study was to search plant extracts that have antimicrobial effect on mutans streptococci. Seed-extract of Casio tora were prepared with ethanol and CHMC-2032, the leaf-extracts from Camellia sinensis extract, was obtained extract, 2 type strains and 20 clinical isolates of mutans streptococci isolated from the interface between orthodontic brackets and tooth surfaces in the orthodontic patients were used in this study. The minimal inhibitory concentration of CHMC-2032 was 5 mg/ml on the S. mutans KCTC 3065, S. sobrinus KCTC 3088, and 8 clinical isolates of S. sobrinus. However, there was no antibacterial effect of seed-extract of C. tora on mutans streptococci. These data suggest that green tea may be more effective than the tea prepared from C. tora in the prevention of enamel decalcification or dental caries around brackets.

家蠶에 寄生하는 Nuclear-Polyhedrosis Virus와 새로운 Microsporidia(Nosema sp. M_12)間의 相互作用

林鍾聲,韓明世 경북대학교 1981 새마을 硏究論叢 Vol.1 No.-

In the application of infectious microorganisms of insects to microbial control the interaction among those pathogens has been considered to be very important factors in causing synergism or intereference. In these respects this research was concentrated on the interaction between the nuclear polyhedrosis virus(NPV) and a newly isolated microsporidia, Nosema sp.(M_12) in the larvae of silkworm, Bombyx mori(L.), including comparisions of their pathogenecity and histopathological symptoms. The interference was observed between the two pathogens were incoculated per os to the second-instar larvae of the silkworm at the same time. In the response of the interaction the degree of interference by was greater than that by the NPV. However, the former pathognn M_12 was not interfered by the challanging NPV while the former NPV was considerably interfered by the challanging M_12 when they were inoculated per os at the intereval of 24 hours at the second-instar larvae. In the histopathological observations the sites of inteference were observed in some tissue like fat body or cell unit though one of the pathogens was dominant in each tissue. From the point of microbial control views it is neither recommendable to use NPV and M_12 at the same time nor the same areas in the case of both pathogens to be used as a microbial insecticide.

Surfactin isolated from Bacillus subtilis has a strong surface tension-lowering activity, together with antiviral, antitumor, fibrinolytic and hypocholesterolemic activities. LC/MS is a simple, rapid and effective technique for the determination of surfactin C in rat serum. The separation of surfactin was achieved on reverse phase column. The mobile phase consisted of 0.1% trifluoracetic acid in water (A) and acetonitrile (B). As a result of analysis of blank rat serum samples, matrix interference was not shown. The values of precision and accuracy were satisfied w the guideline. A newly developed LC/MS method for the determination of surfactin C was successfully applied in its pharmacokinetic analysis.

12-O-Tetradecanoylphorbol-13-Acetate에 의한 HL-60 세포 분화유도중 Vimentin 유전자 전사조절에 대한 AP-1의 역할

임규,김진희,권도원,김승민,이명선,윤경아,손미영,박종일,윤완희,황병두 忠南大學校 癌共同硏究所 1998 癌共同硏究所 硏究誌 Vol.2 No.1

Purpose: To gain insight on the role of AP-1 in transcriptional regulation of vimentin gene during differentiation of HL-60 cells by 12-O-tetradecanoylphorbol-13-acetate (TPA), the levels of vimentin mRNA and AP-1 have been investigated with Northern blot hybridization and DNA mobility shift assay. Materials and Methods: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal calf serum and antibiotics in a humidified 5% CO_(2) at 37°C. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe(Upper strand, 5'-CGCTTGATGAGTCAGCCG- 3') for AP-1 binding activity was mixed with nuclear extracts in a 20 μl reaction volume containing 300 mM KC1, 60 mM HEPES, pH 7.9, 25 mM MgCl_(2), 1 mM EDTA, 1 mM DTT, 60% glycerol, and 2μg of poly[dI-dC]. Results: TPA increased vimentin mRNA levels, with maximal stimulation reached at 24 hr. The level of vimentin mRNA was induced in proportion to the concentration of TPA. TPA-induced vimentin mRNA was almost reduced by actinomycin-D pretreatment. TPA-induced stimulation of vimentin gene was completely reduced by staurosporin pretreatment. In DNA mobility shift assay, AP-1 newly appeared at 24 hr during TPA-induced differentiation and was almost not detected after the pretreatment of staurosporin. Conclusions: These results suggest that the induction of vimentin mRNA during TPA-dependent differentiation in HL-60 cells may be mediated by protein kinases C signal transduction and AP-1 is important to transcriptional regulation.
