The result of an experimental study on the mechanical properties and durability of polypropylene fiber reinforced concrete are presented in this paper. This study has been performed to obtain the properties of PFRC such as strength toughness and durability. The test variables are fiber content fiber types, W/C ratio. PFRC shows the highest strength when the polypropylene fiber content is about 0.2% in concrete, flexural toughness of PFRC was increased remarkably as polypropylene fiber contents were increased to 2.0 vol.%. Also, freeze-thaw resistance and carbonation were somewhat more improved than plain concrete.

Objective : Our purpose of this study is to evaluate the effectiveness of the transcatheter arterial embolization for the management of abnormal uterine bleeding. Materials and Methods : 14 patients with massive or recurrent uterine bleeding underwent percutaneous transcatheter arterial embolization between February 2003 and September 2004. We reviewed 14 cases of uterine artery or internal iliac artery embolization using gelfoam or PVA particles. Results : Good management of uterine bleeding was achieved in 13 of 14(93%) cases. The cause of abnormal uterine bleeding was myoma(5 case), post D & E bleeding(3), acquired vascular malformation(3), pseudoaneurysm(1), adenomyosis(1), and endometrial hyperplasia(1). Conclusion : Transcatheter artery embolization is an effective and life-saving procedure in massive or recurrent uterine bleeding. Early diagnosis and prompt transcatheter arterial embolization is a useful mangement of uterine bleeding.

미로누공에 대한 임상적 고찰

남부현,백승숙 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.2

15 cases of labyrinthine fistula operated by one junior staff from November, 1991 to November, 1993 were discussed. 14 cases were caused by cholesteatoma, and one case was caused by an iatrogenic surgical injury during otoneurologic procedure(petrosal approach). Clinical symptoms were mainly that of complication i.e., serous or suppurative labyrinthitis, facial palsy, brain abscess, meningitis, mastoid fistula and subperiosteal abscess. Temporal bone CT scan showed 100% sensitivity in detecting the lateral semicircular canal erosion, but fistula test proved less useful due to labyrinthine symptoms and high false nagative rate. Postoperative hearing results were more related to the method of fistula repair rather than the size of fistula, presence of perilymph leakage or inadverent perilymph aspiration during matrix removal. A canal plugging procedure, which was helpful in preservation of cochlea function in some cases, may prevent permanent intralabyrinthine fistula formation, and we suggest it as a method in treatment of selected cases of labyrinthine fistula.

양승부,임한혁,최교창 순천향의학연구소 2005 Journal of Soonchunhyang Medical Science Vol.11 No.1

Purpose : To determine the usefullness of transcatheter embolization of arterial bleeding in patients with pelvic bone fracture. Materials and Methods : Between March 2003 and December 2004, we evaluated 13 injuried arteries of eight patients with pelvic bone fracture, All patients underwent angiography, followed by transcatheter arterial embolization using gelfoam. We investigated the vital sign, survival rate and complication of transcatheter arterial embolization. Results : Angiography revealed extravasation of cantrast media in six patients; extravasation and abrupt cut-off of an artery in two. The injured arteries involved(n=13) were internal pudendal(n=4), obturator(n=3), inferior gluteal(n=3), iliolumbar(n=2) and superior gluteal artery(n=1). Transcather arterial embolization was technically successful and there was no complication in all cases. Old age patients(n=2, >60years) died due to hypovolemia and pulmonary complication. Conclusion : Transcatheter arterial embolization of arterial bleeding is a useful procedure in lowering the mortality and complication in pelvic bone fracture.

Ni_3Al상의 형성과 반응확산

정승부 成均館大學校 科學技術硏究所 1996 論文集 Vol.47 No.2

Reaction diffusion and formation of Ni_3AL phase with L1_2 structure has been studied at temperature from 1423 to 1573K using the diffusion couple of (Ni-40.5at%Al)/(Ni-15at%Al) and (Ni-49.2at%Al)/(Nickel). The layer growth of Ni_3-Al phase in the annealed diffusion couple was measured by optical microscope and electron probe microanalyzer(EPMA). The layer growth of Ni_3Al phase in this experimental temperature range was controlled by the volume diffusion mechanism. The rate of layer growth of Ni_3-Al phase was found to be closely related to the composition of NiAl phase. The activation energy for layer growth of Ni_3Al phase was calculated to be 127kJ/mol.

Hi-Grid CFM을 이용한 RC보의 전단 거동에 관한 실험 연구

尹勝照,吉村浩二,梁富弘,李禹鎭 충주대 2003 産業科學論文集 Vol.11 No.-

Recently, many retrofit methods have been developed and applied to real structure in order to improve the life period and safety of structure. Among those, most popular method is using Carbon Fiber Sheet(CFS) as retrofit material because it is lightweight and has high strength. Recent research results, however, show that the CFS is easy to be separated from structure and this reduces the strengthening effect. A method using CFM and high performance mortar is for minimizing these problems. Also, this method is effective to improve the fire resistance and durability of structure, In this paper, the shear strengthening effect of reinforced concrete beam using CFM and mortar is studied through experimental work. Main variables considered in the test are layout of CFM, number of clip, method of retrofit. The results show that the strengthening effect was maximized when CFM is diagonally attached to the beam. When the number of clip is increased, the specimen shows improved strength and ductility after ultimate status. The advance of strengthening effect can be achieved by applying U shape retrofit using CFM and mortar. At 50% of maximum strength, specimens showed bond failure which has been expanded during the loading.

제7차 환경교육과정 특성에 대한 미학적 고찰

이민부,박승규,장의선 한국지리환경교육학회 2001 한국지리환경교육학회지 Vol.9 No.1

제 7차 환경과 교육과정에서는 초등학교와 중·고등학교에서의 환경교육이 균형있는 환경인식을 형성할 수 있도록 가치관, 지식, 기능, 태도, 참여 등 다양한 영역에 걸쳐서 목표를 제시하고 있다. 내용영역에서도‘인간과 환경’, ‘환경문제’, ‘환경보전’이라는 세 영역을 초등학교와 중·고등학교에서 계속적으로 다루면서 심화·확대시키고 있다. 특히 고등학교에서는 이들 세 영역 이외에‘환경과 사회’의 영역 등을 추가하여 학습자들이 자연과학적인 측면에서의 이해에서 벗어나 인문·사회과학적인 측면에서의 접근을 통해 우리의 삶과 환경과의 밀접한 관련성을 인식하고, 환경문제해결에 참여할 수 있도록 하고 있다. 그러나 제 7차 환경과 교육과정에서도 학습자들의 일상적인 삶의 영역과의 관련성을 염두에 두고 있으면서도 대부분의 내용들이 환경파괴나 환경오염, 그리고 그에 대한 대책 등과 관련된 것들이 대부분이어서 학습자들로 하여금 환경적 감수성이나 환경에 대한 아름다움을 통한 환경교육의 가능성이 그만큼 제한되어 있다. 따라서 본 연구에서는 경관을 매개로 한 미학적인 관점에서 제 7차 학교급별 환경교육의 특성을 비판적으로 살펴보고자 한다. The 7th national curriculum for environmental education in elementary and secondary school focuses on consideration of learner’s ability, learner’s activities, and learner’s region of everyday life. The contents of environmental education are scattered subjects in elementary schools and an independent subject as ‘Environment’ in middle school and ‘Environment and Ecology’ in high school of the secondary school. With upgrading of schools, the aims and activities of environmental learning move up from valuecentered, through activity-oriented and to cognition-centered. The esthetic considerations, such as landscape sensitivity, are required for better environmental education curriculum focusing on value and attitudes in everyday life space or region.

자궁선근증의 방사선학적 진단 : 경질초음파의 유용성과 유용한 소견 Usefulness of Transvaginal Sonogram and Useful findings

양승부,최진수 순천향의학연구소 2003 Journal of Soonchunhyang Medical Science Vol.9 No.1

Object : To evaluate the usefulness of transvaginal sonogram for radiologic diagnosis of adenomysis uteri and useful trasvaginal sonogram findings. Materials and Methods : Thirty five patients who were performed both ulㅅrasonography and hysterectomy proved as adenomyosis were analysed by sonographic finding of myometrial echo texture and also included 4 cases of combined myoma. Results : Four pattern of myometrial echo texture were analyzed. The most common type is ill defined heterogenous echo(19 case) but sensitivity is low(69%). And then ill defined heterogenous echo with multiple small cystic echoes(3 case), multiple alterating striation echo pattern(11 case), and single cystic echo(2 case) were followed. Ill defined heterogenous echo with multiple small cysts and multiple alterating striation echo pattern were most reliable findings(100% of sensitivity). Conclusion : Most reliable myometrial echo texture of adenomyosis are ill defined heterogenous echo with combined multiple small cyst or multiple alterating striation echo pattern. Multiple alteraing striation echo is the suggested charateristic finding of adenomyosis.
