Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.

Agranulocytosis, one of the major side effects of antithyroid a gents, probably occurs in less than 0.25% of cases treated with antithyroid agents. It usually occurs within the first several weeks or months after the initiation of therapy, when drug dosage is higher. Most reported cases of agranulocytosis have occurred during the first 3 months of therapy. We describe here a rare case that did not experience the side effect for 6 years of antithyroid agent treatment but presented with agranulocytosis in one month after re-exposure. It suggests that the major side effect such as agranulocytosis can occur in patients who had undergone prior uneventful antithyroid drug therapy.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.
정전압 공급을 위한 전압형 Dual PWM 컨버터의 변조각 지연에 따른 보상 및 순시전류제어

In this paper, a voltage type dual PWM converter which achivcs the bidirectional power flow between a AC supply and a DC bus voltage is described. In PWM modulator, there exsist a time difference between the smaping time and carrier wave, it achives stable modulation even the disturbance in the synchronous AC source voltage. And this paper proposcs the compensation method and the control method related a disturbance of synchronous signal using the low pass filter and phase shifter for the stable modulation. As a result the voltage type dual PWM converter makes the input current wave as sinusoid, and performs the high power factor driving.
n-부틸알코올 플라즈마로 처리된 폴리에스테르의 표면 특성

n-부틸알코올-플라즈마중합박막을 폴리에스테르 표면위에 생성시켜 표면의 특성을 개질 하였다. 폴리에스테르의 표면은 생성된 박막 내의 친수성기에 의해 친수성으로 개질되었으며 친수성의 정도는 박막내의 산소함량과 밀접한 관계가 있었다. 한편 박막은 발수 및 방오의 효과를 갖는 보호성 차단막으로서의 특성도 나타내었다. We have modified surface property of polyster by deposition of the n-butyl alcohol plasma polymerized thin film. The surface property of polyester was modified to hydrophilic and the hydrophylicity depended closely on the oxygen content of the thin films. The thin film has also protactive barrier property, water repellency, and stain proof property.

The purpose of this study was to evaluate the effect of combined use of fibrin tissue adhesive and porous resorbable calcium carbonate on the periodontal regeneration of the class Ⅱ furcation defects in dogs. Class Ⅱ furcation defect was surgically created on the second, third, and fourth premolars bilaterally in the mandibles of six mongrel dogs. The experimental sites were divided into four groups according to the treatment modalities: Control-surgical debridement only; GroupⅠ-calcium carbonate grafting; Group Ⅱ-application of fibrin adhesive only; Group Ⅲ-application of fibrin adhesive after calcium carbonate grafting. The animals were sacrificed at 2, 4, and 12 weeks after periodontal surgery and the decalcified specimens were prepared for histologic and histometric examination. The results are as follows : Clinically, there were no inflammatory response in all groups after 2, 4, and 12 weeks. In the Control group, junctional epithelium migrated apically to the reference notch. In Group Ⅰ, graft materials exfoliated from the defect throughout the experimental periods and new bone was seen in the notch area at 4 and 12 weeks' specimens. At 2 weeks, fibrin adhesive was indistinguishable in Group Ⅱ. In Group Ⅲ, the graft material was maintained in the defect throughout the experimental periods and the amount of periodontal tissue regeneration was greater than other groups. These results suggest that the use of fibrin tissue adhesive in conjunction with porous resorbable calcium carbonate would improve the stability of graft material and inhibit the epithelial downgrowth and contribute to periodontal regeneration.

The distributed species and the kinds of variable microorganism in Pharynx were monitored to the elementary school child. Our purpose was to investigate the distribution of bacteria in Pharynx of child except for adults. Analysis performed the collected sample from 15 students in Chungnam area for 2 days from July 30 to July 31 in 2012. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡsystems. The experiment on microorganism concentration of contact parts carried out and the average of total microorganism was measured. The elementary child's Pharynx were isolated and identified. The isolation rates were major distributied to Gram positive cocci, another Gram negative bacilli and Gram positive bacilli. respectively. The frequently isolated bacteria were G. adiacens. The Granulicatella adiacens is one of the fastidious Gram positive cocci previously described as nutritionally variant streptococci due to their requirement of L-cysteine, pyridoxal, or thiol compounds for growth. These bacteria have been identified as significant causative agents of endocarditis, opthalmic infections, and meningitis. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganism, Elementary child, Pharynx and Larynx
직류 전동기 속도ㆍ토크 제어를 위한 토크전류관측기 설계

In this paper, the load torque observer is designed for speed and torque control of dc motor. Load torque is very sensitive to the variation and disturbance of the input parameters. Also, there is a limitation to design the poles of speed and torque responses within PI controller parameters. Thus, a method is required to compensate the load disturbance without regulate the gain of the speed controller. The proposed system can accurately estimate the instantaneous speed even at the low speed range by using the load torque observer based on the torque component of DC motor The system becomes robust against disturbances using a feed-forward control of the load torque estimated automatically at the speed observer.
