경상북도 영덕군의 하천에 서식하는 점몰개 spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon)의 근육에서 새인두흡충 Clinostomum complanatum (Rudolphi, 1814)의 피낭유충이 발견되었다. 감염된 점몰개는 "yellow grub"인 기생충의 피낭유충으로 인해 표면이 울퉁불퉁하게 보였으며, 수면위에 힘없이 유영하였고 일부 폐사한 개체도 발견되었다. 분리된 탈낭유충의 형태는 혓바닥 모양이었으며, 크기는 2.85~5.89 mm×0.8~1.99 mm였다. 어체당 1~98 개의 피낭유충을 분리하였으며 평균 감염수는 25개로 나타났다. 특히, 성어크기인 평균 7 cm 정도의 점몰개는 100% 감염되어 있었다. 본 연구는 한국의 자연수계에 서식하는 어류에서 C. complanatum 의해 질병이 발생하고 폐사가 일어난 첫 보고이다. The metacercariae of Clinostomum complanatum (Rudolphi, 1814) were isolated in the whole body muscle of wild freshwater fish, spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon) from the local river in Yeongdeok, Gyeongsangbuk-do, Korea. The infected fish with bumpy body surface by "yellow grub" showed erratic swimming behavior and some fish were died. The isolated excysted metacercariae were tongue shaped and 2.85~5.89 mm × 0.8~1.99 mm in size. 1~98 metacercariae were isolated in individual fish and mean infection intensity was 25. All examined adult spotted barbel gudgeon sizing 7 cm in body length were infected. This is the first report of disease outbreak and mortality caused by C. complanatum infection in wild freshwater fish in Korea.

페렴구균에 의한 대동맥염은 국내에서 1예만 보고될 정도로 매우 드문 감염증이다. 저자들은 원발성의 폐렴구균혈증에 합병된 페렴구균 대동맥염 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Bacterial aortitis is rare and without surgical intervention, it usually leads to uncontrolled sepsis or catastrophic hemorrhage, ultimately, resulting in death. In the postantibiotic era, the dominant infecting organisms are Staphylococcus aureus and Salmonella spp.. In spite of frequent pneumococcal bacteremia, vascular seeding is rare and there is only one published report in Korea. We describe a 77-year-old female with primary pneumococcal bacteremia followed by aortitis of the descending aorta, which was successfully treated by aneurysmectomy, wide excision of periaortic tissue, aortobiiliac bypass via prosthetic graft, and antibiotic therapy.

The purpose of this study was to determine the effects of sodium bicarbonate and sodium citrate loading on acid-base balance and anaerobic endurance. The subjects of this study were 6 healthy male university students. Six subjects (VO₂?: 63±10.3ml/㎏/min) were studied on five conditions following ingestion of 300ml solution containing a current sports-beverage (P: placebo) or sodium bicarbonate (B₁:240㎎/㎏ body weight, B₂: 300㎎/㎏ body weight), or sodium citrate (C₁: 240㎎/㎏ body weight, C₂: 300㎎/㎏ body weight). Arterialized-venous blood samples were drawn at specific time (pre-treatment=90 minute before treadmill running test, pre-exercise, recovery 3min, recovery 15min) and analyzed for blood pH, blood lactate concentration and blood HCO₃­concentration. Also, urine samples were taken three times (pre-treatment, pre-exercise, recovery 15min) for urine pH. Anaerobic endurance was determined by measuring exercise time to exhaustion at 95% VO₂? The results were as followings; 1. Urine pH at pre-treatment showed insignificant difference among five conditions. Urine pH at pre-exercise was highest in B₁and lowest in p(B₁>C₂>B₂>C₁>p; p<.001). At recovery 15min, urine oH showed significant difference among five conditions (B₁>B₂>C₂>C₁>p; p<.001). 2. Blood pH at pre-treatment showed insignificant difference among five conditions. But pre-exercise blood pH increased significantly in four conditions except placebo condition. And blood pH was highest in B₂ and lowest in p (B₂>B₁>C₂>C₁<p; p<.01). After 95% VO₂?exercise, blood pH decreased significantly in all conditions. And blood pH at recovery 3min was highest in B₁and lowest in P (B₁>B₂>C₂>C₁>p; p<.05). Blood pH at recovery 15min was higher than that at recovery 3min and didn’t show significant difference among five conditions. Rate of recovery at 15min after exercise was trended to be higher in C₁and C₂. 3. Blood HCO₃­concentration at pre-treatment didn’t show significant difference among five conditions pre-exercise blood HCO₃­concentration increased significantly in four conditions except placebo condition. And blood HCO₃­concentration was highest in B₁and lowest in P(B₁>B₂>C₂>C₁>p; p<.05). After exercise, blood HCO₃­concentration decreased significantly in all conditions but didn’t show significant difference among five conditions. Blood HCO₃­concentration at recovery 3min was highest in B₁and lowest in P (B₁<C₂>C₁>P). Blood HCO₃­concentration at recovery 15min was higjest in B₁and lowest in P (B₁<C₂>B₂>C₁>P). Blood HCO₃­concentration at recovery 15min was higher than that at recovery 3min but didn’t show significant difference among five conditions. Rate of recovery at 15min after exercise was highest in c₁and lowest in B₂(C₁>C₂>P>B₁>B₂). 4. Blood HLa concentration didn’t show significant difference among five conditions at pre-treatment, pre-exercise, recovery 3min and recovery 15min. Accumulation of blood HLa at recovery 3min was highest in B₂and lowest in P (B₂>B₁>C₁=C₂>P). Rate of recovery at 15min after exercise was 45%, 30%, 43%, 46% and 46% in P₁, B₁,B₂, C₁ and C₂, respectively. And rate of recovery was highest in C₁and C₂, and lowest in B₁(C₁=C₂>P>B₂>B₁). 5. There was not significant difference among anaerobic endurances under the five conditions. However, the exercise time to exhaustion in B₁, B₂, C₂ improved 19.5s(4.9%), 53.8s(14.5%), 59.3s(14.8%) and 75.2s(18.7%) compared to P, respectively. From these results, we concluded that ingestion of sodium bicarbonate and sodium citrace prior to exercise induces alkalosis and may affects the improvement of anaerobic endurance, and sodium bicarbonate and sodium citrate can be used as a effective ergogenic aid. And improvement of anaerobic performance induced alkalotic dosage expect to be higher in sodium citrate than in sodium bicarbonate and higher in 300mg sodium citrate/㎏ body weight than 240mg sodium citrate/㎏ body weight.

싱글 튜브 시스템 BTA 工具를 使用한 SM55C 鋼의 深孔 加工 特性에 관한 硏究

全泰玉,全彦燦,沈成輔,張性圭 동아대학교 공과대학 부설 한국자원개발연구소 1994 硏究報告 Vol.18 No.2

The BTA deep hole machining has an increasing demand because of its wide applications and its good productivity. The main feature of the BTA drill is that the tool cutting edges are unsymmetrically located on the boring head. This provides a stabilizing cutting force resultant necessary for self guidance of the boring head. The BTA drills are capable of machining for having large length to diameter ratio in single pass. The study of the accuracy and surface finish of holes produced would reveal quite useful information regarding the process. This thesis deals with the experimental results obtained during single tube system BTA machining on SM55C steel for different machining conditions.

Fin-tube type(Fin-type) heat exchanger has been tested in order to replace the heat exchanger of parallel flow type(P.F-type) which is now widly used in automobile air conditioning system. The following conclusions are drawn by the comparison of the characteristics of the heat exchangers. Evaporator and condenser capacities and COP(Coefficience of performance) were varied as with the compressor speed, outdoor air temperature and air flow rate changed, which much influenced on the characteristics of the air conditioning system. Evaporator and condenser capacities were increased with increasing compressor speed and outdoor air temperature. Evaporator and condenser pressures of Fin- type were decreased by 7% and 5% respectively compared with those of P.F-type. The COP of Fin-type was decreased with increasing outdoor air temperature and compressor speed. The COP of P.F-type was decreased by 14% compared with that of Fin-type.

The granulation of sludge in the UASB reactor is beneficial to stable operation of the reactor at a high volumetric COD loading rate and high hydraulic loading rate, because it improves the setting ability of sludge and the granular sludge acquired has high methanogenic activity. The design of integral biogas?/liquid/solids seperators varies among suppliers of UASB technology. Comples, soluble organic compounds are the first to be hydrolyzed (Stage 1) to simple organics. These simple organics are converted by acid-forming bacteria to C₄H?COOH, C₃H?COOH, CH₃COOH, H₂ and CO₂ in a acidogenic phase(STAGE 2). The higher organic acids are subsequently converted to CH₃COOH and H₂(Stag 3) by acetogenic bacteria. The final step(Stage 4) to produce CH₃ is carried out by me-thano-bacterium. The kinetics of anaerobic digestion of paper wastewaters largely depends on the environmental conditions. The purpose of this study was to elucidate the kinetics of methane production from paper was tewaters in the UASB. A four-step reaction mechanism was proposed for modeling methanogenesis of anaerobic treatment of paper waterwaters.
