The outcome of primary surgery for cleft lip is judged by its effects on the quality of oro-facial function and development. Many surgical techniques have been tried to obtain better results, however, Delaire introduced a technique of functional closure of the lip and nose, based on the findings of no true hypoplasia in the tissues either side of the cleft. In a seven-month-old Asian male patient with unilateral incomplete cleft lip, we carried out the primary closure by modified Delaire's technique. With no alveolar bone graft, the vertical incision on the nasal base was omitted in this patient because of his acceptable symmetry of nose. Also, a small Z plasty was added on the non-cleft side. The V-shaped incisions, whose notch was located on each side of the red vermilion, were designed and beveled incisions were performed for the rehabilitation of lip length and thickness, considering the postoperative wound contracture. We assured that this modification of Delaire's technique could be applied for various cases of primary closure of incomplete cleft lip.

It is very important to arrange the artificial teeth correctly in bucco-lingual (labio- lingual) relation in reconstrcting dentition. Although many anatomic landmarks and techniques have been reported over the years, they are based on westerns. So this study was performd to examine the horizontal relations of mandibular teeth in Korean dentulous adults. 200 volunteers(mean age 22.9) who had natural dentition were selected. The impressions were taken with irreversible hydrocolloid impression material and mandibular study models were fabricated using class I dental stone. Then they were measured with 3-dimensional measuring device specially designed for this study. The results were as follows ; It is better to consider the lingual cusps of the lower posterior teeth as a guide than the linguoaxial surfaces of the lower posterior teeth, arranging the lower posterior teeth buccally to the line which starts from the mesial aspect of the lower canine and continue backward to the lingual aspect of the retromolar pad. It is better to arrange the fossae of the lower posterior teeth buccally to the line which starts from the cusp tip of the lower canine and continue backward to the top of the retromolar pad. The positions of the lower posterior teeth in the denture-bearing area ; considering the fossa as a guide, the 2nd premolar was positioned in center. considering the buccal cusp as a guide, the 1st molar and the 2nd molar were positioned in center. the distance ratio(d/a) was incresed constantly from the lower canine to the 2nd molar d ; the distance between the buccal vestibule(the lowest point) and the buccal cusp tips of the lower posterior teeth. a ; the distance between the buccal vestibule(the lowest point) and the lingual vestibule(the lowest point). The lower canine was positioned lingually($0.11{\pm}0.13$) than the labial vestibule, and the central incisor and the lateral incisor were positioned almost in the imaginary perpendicular plane of the labial vestibule(the lowest point).

Various techniques and diversely designed implants have been developed to overcome anatomic limitations of the maxillary posterior alveolar bone. The OSFE (osteotome sinus floor elevation) technique has been used for maxillary sinus augmentation. Also, $Endopore^{(R)}$ implant was designed to increase the surface area by its sintered porous surface. The purpose of this study was to evaluate the survival rate of $Endopore^{(R)}$ implants placed in the posterior maxilla in association with the elevation of the sinus membrane using OSFE technique, and examine the new bone formation in the sinus. One hundred fifteen $Endopore^{(R)}$ implants in 66 patients were placed in the posterior maxilla by OSFE technique. The implants were clinically and radiographically followed up for an average of 26.3 months. Most implants were stable and radiographs showed that the bone regenerated in contact with the implants. But, 5 implants in 4 patients were removed after the prosthetic restoration and the survival rate was 95.6% during the follow-up period. The height of new bone formed in the sinus was $3.26{\pm}1.04mm$.

Gingival recession could occur after orthodontic or endodontic treatment. This could influence not only functional and aesthetic problem, but also patient's treatment satisfaction. There are a lot of techniques for preventing gingival recession, but laterally positioned flap with subepithelial connective tissue graft could get definite advantages such as increase of keratinized gingival width and harmonious color match between graft tissue and surrounding tissue. Clinician should select a right patient case and diagnosis with clinical and radiography exam. In a surgical procedure, getting enough amounts of subepithelial connective tissue and flap coverage should be taken into consideration. The clinical outcomes in this case report shows laterally positioned flap with subepithelial connective tissue graft could be a treatment with predictive outcome.

Background: We evaluated the role and effects of prolotherapy in patients presenting with lower back pain and detected sacral asymlocation, by retrospectively analyzing the results of prolotherapy performed at our institute. Methods: Twenty-three patients with referred pain in the lower back rather than distinct radiculopathy, were detected to have sacral asymlocation by simple X-ray from May 2004 through July 2005. The patients were treated with prolotherapy and manipulation by the Ongley's method around the lumbosacral junction, iliolumbar ligament, and sacroiliac joint. They were treated for approximately one to two week intervals, and during this period were rechecked by X-ray and evaluated using the visual analogue scale (VAS). Results: A total of 23 patients were included in the study (10 male and 13 female), and the average age was 41 years. The average VAS at the time of visit was B.5, the average treatment time was 4,7 days, and the average VAS after treatment was 2.1. Conclusions: Back pain, and associated leg and buttock pain, originate from several causes. In these case analyses, instability around the lumbosacral area and sacral asymlocation might have been important causes of patient back pain and associated buttock and leg pain. We therefore applied prolotherapy as well as manipulation techniques devised by Ongley to these patients, and obtained good results.

Purpose: The recent advances in microsurgical techniques and their refinement over the past decade have greatly expanded the indications for digital replantations and have enabled us to salvage severed fingers more often. Many studies have reported greater than 80% viability rates in replantation surgery with functional results. However, replantation of multi-level amputations still remain a challenging problem and the decision of whether or not to replant an amputated part is difficult even for an experienced reconstructive surgeon because the ultimate functional result is unpredictable. Methods: Between January of 2002 and May of 2008, we treated 10 multi-level amputated digits of 7 patients. After brachial plexus block, meticulous replantation procedure was performed under microscopic magnification. Postoperatively, hand elevation, heat lamp, drug therapy and hyperbaric oxygen therapy were applied with careful observation of digital circulation. Early rehabilitation protocol was performed for functional improvement. Results: Among the 19 amputated segments of 10 digits, 16 segments survived completely without any complications. Overall survival rate was 84%. Complete necrosis of one finger tip segment and partial necrosis of two distal amputated segments developed and subsequent surgical interventions such as groin flap, local advancement flap and skin graft were performed. The overall result was functionally and aesthetically satisfactory. Conclusion: We experienced successful replantations of multi-level amputated digits. When we encounter a multi-level amputation, the key question is whether or not it is a contraindication to replantation. Despite the demand for skillful microsurgical technique and longer operative time, the authors' results prove it is worth attempting replantations in multi-level amputation because of the superiority in aesthetic and functional results.

When man first walked on this planet, injury must have been a close encounter of the first kind. The outbreak of World War I, during a period of rapid scientific growth in the basic sciences, demonstrated the need to develop better methods of care for the wounded, methods that were later applicable to the civilian population. Trauma is a multisystem disease and, as such, benefits from almost any advance in medical science. As we learn more about the physiology and the biochemistry of various organ systems, we can provide better management for trauma victims. Improved imaging techniques, better appreciation of physiologic tolerance, and increased understanding of the side effects of specific surgical procedures have combined to reduce operative intervention as a component of trauma patient care. On the other hand, because of this rapid development of medical science, only a few doctors still have the ability to treat multisystem injuries because almost doctor has his or her specialty, which means a doctor tends to see only patients with diagnoses in the doctor's specialty. Trauma Surgeons are physicians who have completed the typical general surgery residency and who usually continue with a one to two year fellowship leading to additional board certification in Surgical Critical Care. It is important to note that trauma surgeons do not need to do all kinds of operations, such as neurosurgery and orthopedic surgery. Trauma surgeons are not only a surgeon but also general medical practitioners who are very good at critical care and coordination of patient. In order to achieve the best patient outcomes, trauma surgeons should be involved in prehospital Emergency Medical Services, the Trauma Resuscitation Room, the Operating Room, the Surgical Intensive Care and Trauma Unit, the Trauma Ward, the Rehabilitation Department, and the Trauma Outpatient Clinic. In conclusion, according to worldwide experience and research, the trauma surgeon is the key factor in the trauma care system, so the trauma surgeon should receive strong support to accomplish his or her role successfully.

Wiring techniques in the fixation of patellar fracture are commonly used. Rigid fixation is essential for early rehabilitation. Breakages of wires after the fixation of patellar fracture are common with extracapsular migration if not removed for long term. But, we experienced a case of patellar fracture with early breakage of wiring and migration of the broken wire fragment into the popliteal fossa through the popliteal hiatus in 64- year-old man and we successfully treated this case, using both arthroscopic and open procedures. So we report this unusual case with a review of current literatures.

1960년대부터 우리나라는 증가하는 용수수요에 대한 안정적인 생 공용수 공급, 수력발전, 하천생태계 유지를 위한 하천유지용수 공급 및 하천 연안지역의 홍수피해 경감 등의 목적으로 댐 사업이 본격적으로 시작되었다. 그러나 현재 댐 건설적지의 감소, 환경보전에 대한 인식 증대 및 지역 주민의 반대 등으로 신규 댐건설에 한계가 있는 실정이다. 또한 국제적으로 댐 건설 패러다임의 변화로 지속가능한 개발을 위한 노후화된 댐의 개량이 새로운 방안으로 제시됨에 따라 국내에서도 이에 대한 대안으로 기존 댐 재개발의 필요성이 대두되고 있다. 한정된 자원과 인력을 통해 댐 재개발의 효과를 극대화하기 위해서는 댐 재개발 우선순위 결정이 필수적이다. 국내에서도 이에 대한 연구가 진행되어 수자원공사 및 농어촌공사에서 각각 댐 및 농업용 저수지의 재개발 우선순위 평가기법을 제시하였으나 최근 기후변화로 인한 영향이 고려되지 않았을 뿐만 아니라 공공서비스 향상, 고령화율과 안전, 환경 및 지역사회 등 여러 측면을 고려한 기준이 제시되어 있지 않았다. 또한 국내 댐 재개발 우선순위 평가 기술은 다른 선진 국가들에 비해 기술적으로 많이 뒤떨어진 실정이다. 본 연구에서는 국내 댐 재개발 우선순위 평가기준 개발을 위한 국내외 사례조사 및 비교분석을 통해 기존의 댐 재개발 우선순위 결정 기술에서 나아가 기후변화 및 시대적 환경적 측면을 고려한 다 기준 댐 재개발 우선순위를 개발하여 향후 기후변화 적응 댐 재개발 실행프레임워크 구축 기술에 활용하고자 한다.

Objective : The purpose of this study was to evaluate the influence of a community based group exercise intervention on motor functional capacity. To evaluate the immediate(post-treatment) effects after 6-weeks exercise program on the group exercise intervention(PNF and Circuit exercise). Methods : Subjects-Included persons with stroke who were living in the community. Thirty-seven subjects were randomly assigned to the PNF, Circuit exercise and control group participated in a repeated measures design that evaluated the subjects with pre-treatment, post-treatment(6 weeks). Functional ability outcome measures assessed the motor assessment scale(MAS) and EMG. Both treatment groups participated in exercise cJass three times a week for 6 weeks. Group programs focused on balance, functional motor capacity and walking ability. The PNF program was modified PNF pattem and techniques with emphasis on functional tasks when possible, as well as stretching of the more affected limb particularly in the more affected shoulder. The Circuit program with subjects completing practice at a selies of work station as well as participating in walking races and relay with other members of the group. Results : Compared with the control group, the treatment group had larger improvements in the motor function ability after 6 weeks treatment and Post-treatment test scores were more significant than the pre-treatment score. 1. Motor function were assessed by using MAS, sit to stand, walking and upper function were assessed pre-treatment versus post-treatment measures revealed a statically significant(p<.05). There were significant differences between the groups. Compared with the control group, the treatment group had larger improvements. 2. In the treatment groups, demonstrated difference in the electromyographic activation of biceps, triceps, quadriceps and tibialis anterior muscles on the paretic side in the response to the reaching arm movement and stepping motion in stance. The difference in muscle activation improvement were not statically significant. Conclusion : The results of this study showed that the PNF and Circuit group exercise intervention can improve motor functional ability. This study suggests that the PNF and Circuit exercise programs is appropriate for community-based group exercise principles. It leads to gain and maintain potential function for disabled persons after stroke in the community.
