The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.

폴리에스테르 섬유 감량시스템의 제어를 위해서는 처리조 내에서 감량되는 섬유가 목표 감량치에 도달했는지를 판단해 주는 장치가 필요하다. 본 연구에서는 가성소다용액의 초농도 및 섬유 감량 정도의 정확한 측정과 감량 종료시간의 산출 및 이에 따른 종료신호를 발생할 수 있는 폴리에스테르 섬유 감량기 전용의 자동적정장치를 개발하였다. To control caustic soda treatment system for the polyester fabric reduction, we need the device to determine that the fabric has been arrived target reduction value. In this study, we develope an automatic process titrator for the caustic soda treatment system. Major functions of the target titrating system are accurate measurements of the caustic soda concentration and then producing the end point signal for caustic soda treatment system.

An increasing frequency of methicillin resistant S. aureus(MRSA), methicillin resistant coagulase negative staphylococci(MRCNS) and Enterococcal infection have been observed in recent years. Teicoplanin is a new glycopeptide antibiotic obstained from the Actinoplanes teicomycetius. The molecular structure and spectrum of antimicrobial activity of teicoplanin is simillar to those of vancomycin, and has been reported to have an excellent in vitro and in vivo effect against various gram-positive infections. Therefore, we evaluated the in vitor susceptibility of gram positive cocci, such as, S. aureus, coagulase negative Staphylococci(CNS), and Enterococci to teicoplanin and vancomycin. The total 253 strains consisted of MSSA(40), MRSA(53), MSCNS(47), MRCNS(48), and Enterococci(65). They were assayed by disc diffusion and agar dilution. During the study, 57% of S. aureus and 49% of CNS showed resistance to methicillin. The inhibitory diameter of teicoplanin was 15-20mm in MSSA, 12-19mm in MRSA, 13-24mm in MSCNS, 11-23mm in MRCNS, and 15-22mm in Enterococci respectively, and showed sensitivity in all but 8 strains(3.2%). The range of the minimum inhibitory concentration (MIC) of teicoplanin to MSSA, MRSA, MSCNS, MRCNS and Enterococci were 9.12-2.0㎍/ml, 0.25-2.0㎍/ml, & 0.25-32㎍/ml, 0.12-1.0㎍/ml respectively. One case of S. haemolyticus was resistant to teicoplanin (32㎍/ml) by the agar dilution method. Eight minor (3.2%) and one major(0.4%) error was observed when the MIC and disk diffusion data were correlated with teicoplanin. As for vancomycin the inhibitory diameter was 17-21mm in MSSA, 15-21mm in MRSA, 18-26mm in MSCNS, 18-25mm in MRCNS, and 16-22mm in Enterococci respectively. The range of the MIC of vancomycin to MSSA, MRSA, MSCNS, MRCNS, and Enterococci were 0.25-1.0㎍/ml, 0.25-4.0㎍/ml, 0.5-2.0㎍/ml and 0.5-2.0㎍/ml respectively. One minor error (0.4%) was seen with the vancomycin disk. The MIC90 of MSSA and MRSA exhibited the same results in teicoplanin (1.0㎍/ml, 1.0㎍/ml), and vancomycin(2.0㎍/ml, 2.0㎍/ml). MSCNS and MRCNS exhibited greater MIC90 with teicoplanin(4.0㎍/ml, 8.0㎍/ml) than vancomycin(2.0㎍/ml, 2.0㎍/ml). Incontrase Enterococci were more susceptible to teicoplanin(0.5㎍/ml) than to vancomucin (2.0㎍/ml). Results from this analysis indicated that both teicoplanin and vancomycin were very excellent for gram positive infections, especially those resistant to methicillin.

Recently, Wire-rireless combination study is being studied very actively with the advent of Ubiquitous environment, using wireless device such as PDA, Cellular Phone loading multi-hop communication that connects wired internet network very easily and controls the system and shares the information in anyplace. The past algorithm, wired and wireless combination that connect between Ad Hoc Network and wired network is being focused only on the study of heterogeneous network interface. The proposed algorithm established independent multi-path between source node and destination node to prevent data loss when errors happen in route. The proposed algorithm established independent multi-path between source node and destination node to prevent data loss, and trasmitted data packet to destination node very quickly and promoted network reliabiliy when errors happen in route.

Dentinogenesis imperfecta is an inherited disorder of dentin formation, usually exhibiting an autosomal dominant mode of transmission. Type Ⅰdentinogenesis imperfects occurs in Patients afflicted with osteogenesis imperfecta. Type Ⅱdentinogenesis imperfecta is not associated with osteogenesis imperfects. Type Ⅲ dentinogenesis imperfecta (Brandywine type) occurs in a racial isolate area in the state of Maryland. Clinically, the color of teeth may range from a gray to brownish violet or yellowish brown with translucent or opalescent hue. The enamel often chips and fractures away, allowing speedy attrition of the remaining, poorly calcified. softer dentin. Roentgenographic features include pulpal obliteration, bulbous crowns and short and blunted roots. The cementum, periodontal membrane and the supporting bone appear normal

This study is intended to inquire into the conflict-content of students re-taking college entrance-examinations, and the competitive conditions of living they are confronted with. This study involves the problems of (1) retaking motive of college entrance-examination (2) health (3) mental hygiene (4) self-concept (5) interpersonal relations (6) etc. A total of 511 college freshman and freshwomen (male 269, female 242) who failed to pass college entrance-examinations and successfully entered first-rate Universities were taken for this study. The tools used here were revised forms of the Rotter Incomplete Sentences Blank and response content analysis. The result was that on the whole, health, mental hygiene, self-concept and interpersonal relations were severely affected on proportion to the number of college entrance-examination failures.

탄성 다물체 동력학 해석 프로그램을 위한 중간 처리기 CNU_IP 개발

유진영,김성수 忠南大學校 産業技術硏究所 1996 산업기술연구논문집 Vol.11 No.1

An intermediate processor, called CNU_IP, has been developed to generate and transfer the necessary data from the commercial finite element program ANSYS to the flexible multibody dynamics program AUTODYN7, which is under development. Binary result file reading routines have been developed to extract deformation mode shapes and consistent mass matrices from the ANSYS binary result file. Using extracted deformation modes, the CNU_IP carries out inertia relief computation for the static correction mode based on the component mode synthesis theory. The program also produces lumped mass entries and lumped rotary inertia entries for the flexible body equations of motion by diagonalizing the consistent mass matrices from the finite element model of a flexible body. Various methods to generate lumped rotary inertia entries have been investigated to select the appropriate method. To show the use of CNU_IP, a flexible chassis model of a military jeep has been demonstrated to produce necessary flexible body data for AUTODYN7.

김유진,김현규,권석태 성균관대학교 생명과학자원연구소 1995 生命資源科學硏究 Vol.2 No.1

Thermostable alkaline phosphatase was found from Thermus caldophilus GK24, extreme thermophile. T caldophilus GK24 alkaline phosphatase was found to be inducible. When starved of inorganic phosphate, T caldophilus GK24 produces the enzyme alkaline phosphatase. The addition of inorganic phosphate to growth medium had a repressive effect on enzyme synthesis. T caldophilus GK24 was tested for the production of alkaline phosphatase by the addition of various concentrations of sodium glutamate, bactotryptone, glucose and yeast extract to basal salts. Sodium glutamate was found to be effective for the alkaline phosphatase induction. The enzyme was stable in the pH range of 7-12. The optimum temperature, pH of the enzyme were 75-85℃ and 11.0-11.5, respectively.
