This is a case report on an unusual - heavy buccal frenum in young lady which was treated by frenectomy, vestibuloplasty and total-palatal mucosal free graft. The authors noticed that this abnormal condition lead several chronic complications in young patient as like as premature loss of upper molar teeth, early and rapid loss of alveolar bone around insertion of frenum, over - extended eruption of lower molar teeth and abnormal mandibular movements, etc. After frenectomy and surgical extension of buccal vestiblue on both upper and lower posterior regions, we obtained a full - sized palatal mucosal graft and moved it on upper and lower extension area seperately as two pieces of free grafts to offer inherent function of denture - bearing mucogingiva and same color - matching with oral mucosa and to prevent post - operative relapse of vestibular height. We discussed here about unusual abnormality and their complcations of unusual buccal frenum and its treatment.

Vincristine, vinblastine, ectoposide등과 같이 세포독성이나 항종양 활성을 가진 여러 가지 천연약물을 개발하기 위해 연구ㆍ실험중인데 고형종양을 사용하는 간접적인 활성 시험법과 직접적인 독성 시험법을 이용하며 특히 생강, 방기과등 고등식물서 나오는 물질에서 여러 활성물질을 확인하였고 최근에는 꼭두서니, 개미취등의 oligopepetide에 주목하여 연구가 진행중이다.
퍼지 관측량을 쓰는 알려진 신호 검파 : 통계적 성능 분석
김선용,김태현,송익호,손재철 한국음향학회 1993 韓國音響學會誌 Vol.12 No.3
이 논문에서는 알려진 신호를 검파하는 국소 최적 퍼지 검파기의 검정 통계량의 확률 분포를 정확한 방법과 근사적 방법으로 얻었다. 또한, 컴퓨터 모의 실험으로 국소 최적 퍼지 검파기의 성능 특성과 국소 최적 검파기의 성능 특성을 견주어 보았다. 마지막으로 국소 최적 퍼지 검파기의 기본적인 기능적 특성에 대해서도 알아보았다.
적분검파력 결정 기준에서의 가설 검정과 알려진 신호 검파
김선용,송익호,장태주,김광순 한국통신학회 1996 韓國通信學會論文誌 Vol.21 No.3
In this paper, a new test criterion for binary decision problems is proposed. The integrated power flunction over a parameter interval is first itroduced as an extension of the power function. The concept of the most integrated powerful (MIP) test based on the integrated power function is then introduced. The MIP criterion is to masimize the value of the integrated power function in any paricular parameter interval. As an applicationof the MIP test, the known signal detection problem is considered. The test statistic of the MIP detector for known signals is obtained and an approximation to the MIP test statistic is also considered.
급성 뇌경색증의 뇌동맥내 국소적 혈전용해술에 의한 치료
김선용 대한영상의학회 1996 대한영상의학회지 Vol.34 No.6
Purpose : To evlauate the efficacy of direct intracranial thrombolytic therapy in patients with acute atherothrombotic and embolic stoke. Materials and Methods : Forty-one patients with cerebral thromboembolic disease, all in the area of the middle cerebral artery and including two cases of internal carotid artry occlusion, were treated with microcatheter-directed local intraarterial thrombolysis, using 180,000 to 1,000,000unit urokinase and 15 to 50mg of tissue plasminogen activator (tPA). The time elapsed before treatment ranged from260 to 470 minute (mean : 380 minutes). The effect of treatment was assessed by cerebral angiography, by CT and by the clinical outcome. Resulsts : For 25 patients (61%), complete vessel recanalization was successful, In eightand three cases, respectively, the result was partial recanalization and residual stenosis. In 21 patients (51%), both acute neurologic and functional outcomes improved significantly within 24 hours and in 92% of patients, within one month. Hemorrhagic transformations occured in five patients (12.2%), and in five others there were high density lesions around the basal ganglia and temporal lobe, which was cleared on CT within 24 hours This suggested transient extravasation of the contrast media rather than true hemorrhage. tPA showed better results than urokinase in terms of the rate of recanlization (68.7% vs 56.7%) and the occurrence of hemorrhagic infarction(6.3%vs 16.9%). Conclusions : Local intraarterial cerebral thrombolysis is thought be an effective method in the treatment of acute brain infarction, but in some patients may cause intracerebral hemorrhage in some patients.
