This paper is concerned with High Frequency, High Voltage Generator for X-ray using zerovoltage soft-switching PWM DC-DC power converter by resonant method, which makes the most of the parastic IBC parameters of high-voltage transformer link, for diagonostic X-ray power generator. The converter circuit basically utilizes phase-shift pulse width modulated series resonant full-bridge PWM DC-DC high-power converter operating at a constant frequency;25kHz. The high-frequency switching operation of the inverter has some effective advantages with consist in the physical reduction in size and weight and lowered acoustic noise. The converter output regulation is digitally controlled using DSP(Digital Signal Processor) for obtaining a fast rising time and adjust output voltage within a wide load range. This converter characteristics are evaluated in terms of computer-aided analytical and experimental results.

This experiment was carried out to obtain indispensable information to establish comprehensive cultural method of rice in direct seeding on dry paddy at Chungbuk Agricultural Research and Extension Services. Effect of seeding date on dry matter production, yield components and yield were studied. Seeding on May 5 ensured the highest maximum number of tillers, while transplanting on May 20 gave the highest rate of effective tillers. Number of effective tillers was greater in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. Lengths of upper three leaves were increased at later seeding, but leaf width was not affected by seeding date. Ratio of leaf blade weight was higher in earlier seeding during 30 days before heading but was higher in later seeding during 30 days after seeding, and was higher in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. CGR, RGR and NAR were not significantly different among seeding dates during 30 days before heading, but were lower in later seeding during 30 days after seeding. LAR was not affected by seeding date during 30 days before heading, but was higher at seeding on May 5 in heading date and during 30 days after heading. Dry weight of leaf blade, leaf sheath and culm, ear and total biomass during 30 days before heading and heading were highest in May 5 seeding. Daekwanbyeo and Hwaseongbyeo in May 5 seeding and Hwajinbyeo in April 20 seeding brought the highest yield with greater number of spikelets, higher ripening ratio and greater 1,000 grain weight, and harvest index and grain/straw ratio were Increased at earlier seeding. There were significantly positive correlations between number of panicles per m2 and LAI at 30 days before heading and heading, dry matter weight of leaf blade and total mass at heading. On the other hand, there were significantly negative correlations between seeding date and ripened grain ratio. 1,000 grain weight and yield, and between 1,000 grain weight and leaf length of 2nd, respectively.

고동현,정한성,김성오,이제호,최형준,최병재 대한소아치과학회 2007 大韓小兒齒科學會誌 Vol.34 No.1

치아우식증이나 치주질환으로 치아를 상실한 경우 여러 가지 방법으로 수복 치료할 수 있으나 그 중에서 임플란트와 치아 이식에 대한 관심이 높아지고 있다. 최근에는 치아 이식에 대한 성공률을 높이기 위해서 치아를 형성시키고 발육시키는 과정에 관한 많은 연구가 이루어지고 있다. 치아싹 이식은 생체 내와 생체 외에서 연구되고 있고, 생체 내 이식은 쥐와 생쥐, 고양이, 개 등 여러 동물에서 시행되고 있다. 이러한 생체 내 이식은 대부분 구강 외에서 시행되고 있으며 구강 내 이식에 대한 연구는 드물다. 본 연구는 악골 내에 이식한 치아싹이 발육되고 석회화되는지 관찰하기 위하여 성숙한 흰쥐의 상악 제 1 구치를 발치하고 그 발치와에 임신 13.5일 된 태아쥐에서 모상기의 하악 제 1 구치의 치아싹을 이식하고 2. 6 개월 후 회생하여 방사선학적 그리고 조직학적으로 관찰하여 다음과 같은 결과를 얻었다. 1. 2 개월과 6 개월 동안 악골 내에 이식한 치아싹은 석회화된 치아 조직이 형성 되었고 치아 조직에서 상아질과 백악질, 치수 조직이 관찰되었으며 법랑질 공간 주변은 상피로 둘러싸여 있었다. 2. 6 개월 동안 구강 상피 하방에 위치한 치아 조직은 상피로 둘러싸여 있었고 주위에 치주인대 및 결합조직이 관찰되었다. 3. 이식한 시간이 경과함에 따라 치아 형성이 진전되었으나 치아 조직은 크기가 작았고 형태학적으로 완전하지 못하였다. In case of missing tooth caused by dental caries or periodontal disease, it can be restored by various methods, and there has been much interest in implant and tooth transplantation. The success of tooth transplantation is going to be attained through the knowledge of growth, development and calcification of tooth. Tooth transplantation has been experimented in vivo and in vitro. Many animals such as rats, mice, cats and dogs are used for tooth transplantation experiment in vivo. In most experiments, tooth was transplanted into the extraoral site, but rare into the intraoral site. In this study, to observe the capacity of formation and mineralization of tooth germ, first molar of a matured white rat was extracted and the cap stage tooth germ of a 13.5 Embryonic day embryo rat was transplanted into the extracted socket. The rats were killed 6 months later and the radiographical and histological results are as followings. 1. Tooth germ transplanted for 2 and 6 months are developing calcified tooth material such as dentin, cementum, pulp tissue, and epithelium around enamel space in the maxilla was seen. 2. The epithelium around enamel space was located beneath the oral epithelium and contained connective tissue and periodontal ligament. 3. Tooth formation was progressed as transplantation period, but the size of newly formed tooth was small and the shape of tooth was incomplete.

김현준,김학성,김세찬,유동욱,원충연 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.2

This paper deals with a phase-shifted PWM high-frequency series resonant DC-DC converter using IGBTs. The converter output voltage regulation is digitally controlled using DSP(TMS320C31) for a fast rising time and low ripple output voltage. A PID controller and feed-forward controller is adopted as a controller and implemented on software. Simulation technique are employed to describe resonant converter behavior, which can present system output exactly and calculate in short time, by applying numerical method to the state equation of each equivalent circuit. And the simulation results are verified as compared with experimental results.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS) that is commonly found on the human perineal skin. Contrary to other CNS, S. lugdunensis is a rare contaminant in cultures and has the potential to cause clinically significant infections, including infective endocarditis. Infective endocarditis due to S. lugdunensis have been known to resemble endocarditis due to S. aureus because of its aggressive clinical course and high mortality. We report a case of infective endocarditis caused by S. lugdunensis in a 21-year-old woman. She was cured of the infection with surgical and antibiotic therapy. S. lugdunensis에 의한 감염성 심내막염은 국내에서보고가 없었던 매우 드물지만 다양한 합병증과 높은 사망률을 보이는 감염증이다. 저자들은 S. lugdunensis가 수술적 치료와 항생제 치료로 완치된 감염성 심내막염 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

김휘준,이동화,이성희 순천향의학연구소 1996 Journal of Soonchunhyang Medical Science Vol.2 No.1

1984년 1월부터 1992년 12월까지 9년간 순천향대학병원에서 다발성골수종으로 진단된 28명의 환자를 대상으로 임상 검사 소견 및 생존 기간을 분석하고, 골수천자도말에서 형질세포 분화 정도에 따른 형태학적 분류를 하고, 골수생검상 형질세포 침윤 양샹에 따른 분류를 한 후 이와 같은 분류가 임상 경과 및 예후와 어떤 관련이 있는지를 알아 보았다. 1. 골수천자도말에서 형질세포 분화 정도에 따른 분류를 하여 mature형과 immature형을 비교한 결과 진단 당시 임상 및 혈액학적 변수들간에 유의한 차이는 없었다. 2.골수생검상 형질세포 침윤 양상에 따른 분류를 하여 diffuse형과 packed형 을 비교한 결과 진단 당시 임상 및 혈액학적 변수들간에 유의한 차이는 없었다. 3. 위와 같은 분류가 예후 추정인자로서 의의가 있는지를 알아 보기 위해 평균 생존율을 구해 보았으나 유의한 차이는 없었다. 이상과 같은 결과는 본 연구의 증례가 너무 적었고, 처음 진단이 늦었으며 대부분의 환자가 고령이어서 일찍 치료를 포기한 이유로 생각되며, 추후에 더 많은 증례에 대한 연구가 계속되고 환자에 대한 교육을 실시하여 추적 관찰을 계속한다면 위와 같은 분류 방법이 다발성골수종의 예후를 추정하는데,유용한 지표로 사용될 수 있으리라 사료된다. The maturity of myeloma cells in the bone marrow aspirates and the pattern of infiltratin in the biopsy are known to be highly significant in predicting the prognosis. This study was performed to analyse clinical. hematological, and morphological features of the bone marrow smears and biopsy in multiple myeloma at the time of diagnosis and investigate the correlation between clinical and pathologic findings for the evaluation of survival rate. The subjects for the study were 28 cases of multiple myeloma from January 1984 to December 1992 diagnosed at Soonchunhayang University Hospital. There were no statistical differences between clinical parameters and cell types and pattern of infiltrating in the bone marrow. And there were no statistical differences in survival rate depending on the cell types and pattern of infiltration pattern in the bone marrow. Above findings seemed to be resulted from insufficient subjects and failure of complete follow-up study. However, if a cooperative study of the impact of morphological classification in myeloma is performed in the future, morphological classificatin of myeloma could be considered as a prognostic factor.
