설정현,백석윤 한국초등수학교육학회 2007 한국초등수학교육학회지 Vol.11 No.2

최근 수학교육에서는 수학 쓰기 활동이 활발히 연구되고 있다. 이에 본 연구에서는 '수학동화'라는 쓰기 활동을 새롭게 구안하여 학생들에게 적용해 보고, 이를 통해 나타나는 학생들의 인지적 정의적 특성을 분석하는 데에 그 목적이 있다. 수학동화 쓰기 활동을 하면서 많은 학생들이 이미 학습한 수학적 지식에 대한 반성적 사고를 통해 학습한 수학 내용을 재구성하고 응용하였다. 또한, 수학동화 쓰기 활동을 하는 동안 학생들의 수학적 의사소통 활동이 매우 활발해졌으며, 이를 통해 학생들은 학습한 수학적 지식에 대한 재학습의 기회를 갖게 되었다. 학생들은 수학동화 쓰기 활동을 통해 수학의 실제적인 활용 장면을 스스로 찾을 수 있게 되었으며, 수학 학습에 대한 필요성을 깨닫게 되었다. 뿐만 아니라, 활동 과정에서 많은 학생들이 수학 학습에 대한 즐거움과 성취감을 느끼게 됨으로써 긍정적인 수학적 성향을 형성해 나갔으며, 스스로 의지를 가지고 활동에 참여함으로써 수학학습에 집중하게 되었다. 수학동화 쓰기 활동을 하는 동안 학생들이 보여준 이와 같은 특성은 오늘날의 수학교육이 추구하고자 하는 긍정적인 측면들을 많이 보여주고 있으므로, 학교 현장에서 적극 활용해 볼 만 하다. Within the field of mathematics education there is an active movement which attempts to apply more beneficial learning activities, like mathematical writing activities, for the students. In this context, the current study attempts to identify elementary school students' cognitive and affective aspects as they participate in a novel writing activity, the 'mathematical fairy tale.' Some positive outcomes from the mathematical fairy tale writing activities were as follows: First, from these mathematical writing activities, students began to reconstruct and adapt the mathematical contents they've learned through their reflective thinking. Second, while the mathematical fairy tale writing activities were going on, the communication of mathematics was greatly animated between the students, and they could get the restudying chance about they've learned. Third, from these mathematical writing activities, many of students became discover the practical using case of the mathematical contents they've learned and they perceived the necessity of the mathematics learning. Forth, from these mathematical writing activities, most of students felt the delights of the mathematics learning and the achievement, so they indicated that their attitude for the mathematics course was changed positively. Lastly, students began to concentrate on their mathematics learning through participation in mathematical fairy tale writing activities of their own accord.

김정철,정영식,우상현,이대훈,설정현 大韓成形外科學會 1990 Archives of Plastic Surgery Vol.17 No.3

Soft tissue expansion is widely used technique in plastic surgery and provide new method or reconstruction in postburn or posttraumatic alopecia, wide scar, tattoo, benign tumor, congenital deformity of ear or hand and deformed breast, etc. During recent 3 years, we experienced soft tissue expansion in 29 cases and evaluated the operative techniques, results and complications as follows. 1. Tissue expansion is very effective in soft tissue reconstruction, especially in scalp for young age. But, it needs careful selection of patient in application for reconstruction of face, neck or extremity. 2. We experienced major complications in 6 cases (20%) as implant exposure, skin necrosis and infection. In these cases, the expanders were removed immediately and applied secondary insertion after 5 or 6 months. 3. Minor complications as partial necrosis on wound margin, bullae on skin, hematoma, pain or tightness and pressure on the valve were found in 7 cases (24%) which made full expansion with careful conservative management. 4. Sufficient preoperative evaluation and careful patient selection with expander type should be done before tissue expansion, and so better results will be obtain. The soft tissue expansion is simple and useful method, but it needs more study and clinical experiences which will provide the better aesthetic results.

The intraoperative vascular expansion to overcome arterial defect on microanastomosis of rat femoral artery was evaluated. The present study was conducted to compare the intraoperative vascular expansion group, with the simple vascular dissection group, on the patency rate of the sutured vessels, and the histological changes of anastomosed sites and expanded sites of the vessels during the healing period. The artificial arterial gap has made in 10mm of length, on the proximal femoral arteries of the rats. The adjacent femoral artery has dissected from soft tissue bed about 20mm of length and expanded with the vascular expander., and then the microanastomosis has performed with 10-0 ethilon. The control group has simply dissected on the adjacent femoral artery and microanastomosed. At 20 minutes, 3days, and 5weeks, the patency rates and histologic findings has evaluated. As a result, the patency rate of the sutured vessels in both groups were not significantly different for each groups at postoperative 20 minutes and 3 days, but the intraoperative vasular expansion group revealed sigificantly higher patency rate than the simple vascular dissection group at postoperative 5th week. In our histologic examination at 20 minutes after microanastomosis, the initial intimal loss and microfragmentation of internal elastic lamina, on microanastomitic site and expanded site, were seen in both groups. the expansion group has moree active regeneration of the intima and the internal elastic lamina. As a conclusion, the intraoperative vascular expansion is very effective method to overcome the moderate vascular gap and has stimulatory effect on regeneration of the injuried vasular walll, especially in intima, But before the clinical application, any other study with more cases should be performed.

Since Dr. IIIouz had systematized the liposuction, it becomes a powerful weapon to the plastic surgeon in body contouring with the advantage of the inconspicuous scar, relatively simple technique, effective removal of the fat tissue, and a little percentage of complications. Generally, the indications are the treatment of localized fat accummulation, gynecomastia, lipomas, lymphedema, etc. Liposuction can be combined as adjunctive procedure for the abdominoplasty, dermolipectomy, rhytidoplasty, reduction mammaplsty, etc. Many patients wish to have multiple areas treated. In such instances, the removal of over 1500cc of material are necessary for optimal aesthetic result. However, when over 1500cc of material is removed, anesthetic requirement, fluid replacement, and treatment of blood loss become important. We have treated 13 patients in 2nd, 3rd and 4th decades who had average 1718cc aspirated on multiple areas such as the abdominal, paralumbar, gluteal-femoral & calves regions with autotransfusion under general anesthesia by conventional vacuum suction. And we treated another 3 patients using ultrasonic aspirator with blunt ended cannula tip. The ultrasonic liposuction is comfort procedure and bloodless surgery which dose not damage vascular and nervous structures. So, out - patient surgery was possible in simple case. And we evaluated the decreased amount of thickness and volume by magnetic resonance imaging. The complications are negligable. One case has the transient paresthesia, two cases with transient skin irregularity and contour irregularity, respectively, and two cases of 4th decade with permanant skin redundancy. All patient were satisfied to the result. We believe that large-volume liposuction is safe and efficacious method when attention is directed to such important aspect of patient care as anesthesia, fluid replacedment, and blood loss.

In recent years it has been shown that it is possible to keep a flap viable by retrograde circulation through the draining vein, instead of the feeding artery. The purpose of this study was to investigate the viability of four types of venous flaps : 1) venous flap with single venous inflow and single outflow, 2) venous flap with single venous inflow and double venous outflow, 3) venous flap with double venous inflow and single venous outflow, 4) venous flap with single vein. And the control group was carried out as the composite graft. Twenty-five rabbits undergone venous flap surgery for comparison of flap survival rate were studied. Mean survival of skin flaps were shown : 1) group 1-63.4%, 2) group 2-75.2%, 3) group 3-96.8%, 4) group 4-45.6%, 5) control group-total necrosis. Results of study validated that flap viability was dependent on the number of vascular pedicle in venous flaps, and the more venous inflow than venous outflow, the flap survival was increased.

Many plastic surgeons are called upon from time to time to carry out skin grafting procedures. Often the sebsequent donor site does not receive the attention or expert management it deserve. The result is an inordinately uncomfortable patient or, worse, delayed healing or infection with conversion to full-thickness loss. The most important goal of donor site care is rapid re-epithelization without infection and minimum discomfort to the patient. So, many techniques have been used in managing the split-thickness skin graft donor site. Basically, these can be categolized into the following dressing classification: occlusive, open and semi-open method. During the past 6 months, 48 cases of the donor dressing at plastic surgery department of Severance Hospital. In the author's observation, the semi-open method is rapid re-epithelization with minimum discomfort compare ti open and occlusive method. Which result suspect the early wound open and dry up after bleeding control is the key of donor wound healing.

In the department of plastic surgery, Yeung Nam university hospital, 38 cases of thumb tip injury were immediately reconstructed during last 4 years. We analysed and followed up the patient and obtained following results: 1. Thumb tip injury was most commonly involving in third decade with 18 cases (45%) and occurred predominantly in male with 34 cases (90%). 2. The injuries were mainly caused by press machine with 19 cases (50%). 3. Crushing was predominant nature of the injuries with 19 cases (50%). 4. The thumb tips were most commonly involved at the level of nail matrix with 16 cases (42%). 5. In 28 cases (73%), only thumb tip was injured without other combined injury. 6. Rt. side (23 cases, 60%) was more commonly involved than Lt. 7. Cross-side finger flap revealed the best result for the treatment of distal amputation of nail matrix. Contrarily in proximal amputation, microreplantation had the best result in both the cosmetic and the functional standpoint.
