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.

This experimental study was done to compare the efficacy of Korean and Chinese Carthami Semen on analgesic effect and remedy of inflammation and arthritis. The results were as follows; 1. In analgesic action on the writhing syndrome in mice induced by 0.7% acetic acid, Korean and Chinese Carthami Semen extract group showed significant decrease in comparison with control group. And in analgesic action on the writhing syndrome in mice induced by Acetylcholine HC1, Korean and chinese Carthami Semen extract group showed significant decrease in comparison with control group. 2. In Anti-inflammatory effects, Chinese Carthami Semen extract group showed significant decrease at 150 and 180 minutes after inducing paw-edema in comparison with control group. 3. In the method of adjuvant arthritis, orally administered for 21 days, Korean Carthami Semen extract group showed significant inhibition of the hind paw edema after 1 day and 21 days. Whereas Chinese Carthami Semen extract group showed some reduction, but the results didn's show significant decrease. 4. In the level of leucocytes count, Korean and Chinese Carthami Semen extract group showed significant decrease in comparison with control group. And in the level of total protein. CRP and glucose, Korean and Chinese Carthami Semen extract group didn't showed significant change in comparison with control group.

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

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.

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.

폴리에스터(PET)의 표면성질을 친수성으로 개질하기 위하여 Perfluoropropene을 13.65MHz의 RF 발진기를 이용하여 PEF직물상에 플라즈마중합하였다. 이때 생성된 박막의 표면성질을 플라즈마 후반용(post reaction)과 불포화결합을 이용하여 친수성으로 개질하였다. 친수성의 개질 효과는 적외선분광스펙트럼에서 수신기의 생성과 불포로 개질하였다. 친수성의 개질 효과는 적외선분광스펙트럼에서 수산기의 생성과 불포화결합에 대한 Br₂의 첨가반응에 따른 이중결합의 소멸로서 확인할 수 있었고 친수화의 정도는 마찰대전압을 측정하여 평가하였다. For the modification of PET surface, Perfluoropropene was plasma polymerized on the PET fabrics by means of 13.56MHz radio frequency generator. The surface preperties of PET fabrics were modified from hydrophobic to hydrphilic by application of the post reaction and hydration reaction of unsaturated bonds present in plasma thin film. The evaluation of the degree of hydrophilicity was performed by measuring friction static voltage of PET fabric with cotton fabric.
