The purpose of this study is to lead learners to observe the natural objects and phenomena correctly, and set up practical examples of effective methods for the study of elementary science by the learners participating at positive activities in the study with absorbing interest. I have analysed the problems existing in the study of elementary science which is being progressed in the proper educational institutes upon my investigation of the study from the following points of view : 1. Learning method in elementary science which pupils are desirous of. 2. Constitution of school course requested in the study of elementary science 3. Interest of the pupi1s in their study of elementary science. 4. Response shown by the parents of the pupils ill their own study of elementary science. As the result of my analysis mentioned above, the followinig problems have been detected : 1. The further pupils advance in their study of the subject, the more they are interested in independent study of method, and the more they are desirous of individual experiment needed in its study. 2. Questions, instructions, and demonstrations given on the part of teachers have great influences on durability of the pupils' interest and concern in consequence of their teaching methods. 3. The result of my analysis shows 5,2% of the pupils are fond of the subject, and 22,3% of them are not; (N=578) the followings are the reasons shown in otation as described : a. Contents of the subject are hard to make out. b. Vast bulk of contents of the subject is unbearable. c. Scientific terms used in the subject are inintelligible. d. The subject is uninteresting. The reasons of their being fond of the subject are : a. They have chances of conducting experiments and observation on the subject. b. They can enjoy pleasure experiments on the subject. 4. The subject meets with little response on the part of the parents on the occasion of their own study of the subject, proving of little service to them. The reasons ascertained are : a. They lack understanding of the contents of the subject. (54.2%) b. They can hardly afford to prepare for research materials (36.2%) This shows the fact that we can hardly warrant any sanguine expectations regarding their home learning of the subject, The following are methods of teaching conducted practically in order to solve the abovementioned problems, the result of which got the Pupils interested intensively in their study of the subject, bring on a remarkable change in their learning attitude : 1. Teaching method by funny form style ( applied by the lesson, "Light and Shawdgw", 2nd Pear grae) 2. Teaching method by vigorous mannerr of acfivity in teaching (applied by the lesson, ('Eleectric Current and Magnetic Field, 6th year grade) a. Investigation of the pupils, readiness. b. Presentation of phenomena for independent study of the subject. 3. Teaching method by analysis of teaching materials.

목 적 : 본, 증례보고는 대퇴동맥을 천자하여 INTERVENTION 시술 시 발생한 Pseudoaneurysm과 만기 신부전 환자 팔(AVG)의 시술 시 발생하는 혈관 Rupture시 Balloon을 지속적, 반복적 확장하여 지혈하는 치료법이 적용되지 않는 환자를 대상으로 시행하였다. Anatomy상 Joint부위나 투석으로 인하여 계속 인조혈관을 사용하는 환자에 있어 수술적 치료 또는 Graft stent 삽입술을 이용하는 치료보다 Closure Device를 이용하여 문제점을 해결 하였다. 결과 및 고찰 : 중재적 시술 시 언제든지 예상치 못한 상황에서 문제가 발생하기도 한다. Pseudoaneurysm 발생 및 AVG Rupture시 상황에 따라 대부분은 수술적 치료 및 Graft stent 삽입술을 시행하고 있다. Stent 삽입술은 환자에게 비 침습적인 시술 방법이긴 하나 Complication 발생 시 병원마다 상황에 맞는 필요로 하는 size에 stent등의 의료기구가 없을 수도 있으며 또한 지속적이고 반복적인 치료를 요하는 환자에게 적합하지 않은 치료법이 될 수 있다. 따라서 투석 환자의 AVG나 Peripheral artery Anatomy의 Joint 부위에 문제 발생 시 Closure device을 이용하여 지혈하는 방법은 매우 유용한 시술 방법이 될 수 있다고 사료된다.
