Not infrequently overexposed or underexposed x-ray films impose difficulty in interpretation necessitating repeated radiography. However, repeated examination is not always possible because of the transfer, discharge, and dying of the patients. Then, retonning of improper films is much desirable expecially when such films are of considerable clinical and academical importance. The authors carried out a series of experiment to improve the tone of the overexposed and underexposed x-ray films by different exposure times. during duplicating the overexposed film, the film density became bright and imaging details were improved by increasing the exposure time. Underexposed film, however, did not showing any improvement of imaging details but darkened only of overall film density. Therefore, qualified reproduction of overexposed x-ray film using the x-ray film duplicator was easy to do and valuable in the management of film quality without any damage to the original film.

Purpose: To determine the CT findings of an acute pulmonary thromboembolism for the prediction of response to anticoagulant therapy. Materials and Methods: Forty-eight patients diagnosed with a pulmonary embolism underwent anticoagulant therapy, and underwent pre- and post-treatment CT scans, were selected to be part of the study. Pre-treatment CT scans were retrospectively reviewed for the number and degree of emboli, right ventricular to left ventricular (RV/LV) diameter ratio, pulmonary arterial to aorta (PA/aorta) diameter ratio, ventricular septal bowing, consolidation, mosaic perfusion, and pleural effusion. The response to anticoagulant therapy was assessed by a change in embolic burden on pre-and post-treatment CT scans. The 48 patients were divided into two groups: good responder and poor responder. The pre-treatment CT findings were compared by group to determine if there were any differences in the CT findings. Results: Thirty patients were categorized as good responders (62.5%) and eighteen patients as poor responders (37.5%). A pleura-based wedge-shaped consolidation was observed in 9 of 18 cases (50%) from the poor responder group and one of 30 (3%) cases from the good responder group. The comparison of the finding by group was found to be significantly different (p<0.001). No other CT findings were significantly different between the good and poor responders. Conclusion: The pre-treatment CT scans of patients with acute pulmonary embolism indicate that pleurabased wedge-shaped consolidations can predict a poor response to anticoagulant therapy. 목적: 급성 폐색전증 환자에서 항응고제 치료에 대한 폐색전 감소를 예측할 수 있는 CT 소견이 있는지 알아보고자 하였다. 대상과 방법: 초기 CT에서 급성 폐색전증으로 진단되어 항응고제 치료를 받은 환자 중 치료 전과 후에 CT를 시행한 48명의 환자를 대상으로 하였다. 치료 전 CT 영상에서 폐분절에 따른 폐색전의 수와 크기, 우심실 대 좌심실 직경비, 폐동맥 대 대동맥 직경비, 심실중격 만곡, 폐경화, 모자이크형 저관류, 흉막삼출액 등의 유무를 후향적으로 평가하였다. 항응고제 치료에 대한 반응은 치료 전후의 폐색전 양의 변화 정도로 하였고, 그 변화의 차이에 따라 48명의 환자를 반응군과 비반응군으로 나누었다. 항응고제 치료 후의 반응군과 비반응군 간에 치료전 CT 에서 소견들의 차이가 있는지 분석하였다. 결과: 폐색전증 환자 48명 중 30명(62.5%)은 항응고제 치료 후 반응이 좋았던 반응군이었고 18명(37.5%)은 비반응군이었다. 흉막에 기저를 둔 쐐기모양의 폐경화 소견만이 비반응군의 9예(50%)와 반응군의 1예(3%)에서 보여 통계학적으로 유의하게 차이가 있었다(p < 0.001). 다른 CT 소견들은 항응고제 치료 반응군과 비반응군 간에 의미 있는 차이가 없었다. 결론: 급성 폐색전증 환자의 치료 전 CT에서 흉막에 기저를 둔 쐐기모양의 폐경화 소견이 보이면 항응고제 치료에 대한 폐색전 감소 효과가 좋지 않을 것임을 예측 할 수 있다.
종격동과 폐문 임파절을 침범한 원발성 아밀로이드증: 1예보고

아밀로이드증은 인체내 여러조직에 불용성 원섬유 단백질의 침착이 일어나는 드문 질환이다. 임파절을 침범한 아밀로이드증의 방사선학적 소견은 국내에서 보고된바가 없다. 저자들은 종격동과 폐문임파절을 침범한 아밀로이드증 1예의 단순 흉부 X선 사진과 전산화 단층촬영 소견을 보고하고자 한다. Amyloidosis is a rare systemic disease caused by extracellular accumulation of insoluble fibrillar material in various tissues. The radiographic findings of amyloidosis involving the lymph nodes have not been previously reported in Korea, and we report a rare case of primary amyloidosis involving the mediastinal and hilar lymph nodes, with CTand radiographic appearances.

This paper aims at explaining the function of the ‘-si-(-시-)’ as a syntactic marker that agrees with the subject being honored by the speaker. Here I considered that only the subject being honored by pragmatic level could realize ‘-si-’ in the sentence and examined it by dividing into general construction which has one subject and some disputed construction as like so-called double subject construction and some construction which has genitive or locative NP being honored. Especially I noticed that in the general constructions there are no exceptions at the realization ‘-si-’ by the honored subject. By that I guessed it will be the same case on the other constructions. To prove it, I regarded the double subject construction as the phrase-verb construction and to the construction which has genitive or locative NP being honored I suggested that the subjects in these sentences could be honored by the process of the metonymy which can make it the same as the [+honored] person.(Inha University)

This study is a proposal of quality scale and measurement for the Mobile Hospital Information System Usability used to the Chungnam National University Hospital in Daejeon Korea. This study is to provide decision- making guideline for hospital managers and to provide feedback for the users`information needs in Mobile Hospital Information System. The target people of the study were medical doctors in Chungnam National University Hospital. The service contexts of usability were request of medical Care, Vital sign check of Patient, Care Agreement of Patient, Blood management, Check of care state, Sign of choice doctors, Query of doctor order and patient measurement result. The Usability factors were the efficiency, effectiveness and satisfaction of quality model ISO9241-11. This study shows that the Mobile HIS is used for the communication and education between doctor and patients. Especially, The Care Agreement of Patient is a part of the most utilized in the Mobile HIS.
