The Orbital fracture which is often combined with midface fracture can cause decreased visual acuity, limitation of eyeball movement, diplopia, enophthalmos, etc. Traumatic orbital fracture causes change of orbital volume, results in diplopia and enophthalmos thus, accurate repositioning of displaced bone and reconstruction of orbital defect with autogenous materials(cranial, rib, iliac bone, cartilage and fascia lata) or alloplastic materials(gelatin film, polyglactin mesh, methylmethacrylate, Teflon, silicone, Supermid, hydroxyapatite and metal). The key point of reconstruction of orbit is accurate repositioning of displaced orbital floor, lateral, medial orbital wall and sufficient bonegraft in anatomical defect. As this cases, we obtained good results through transconjunctival and coronal approach who were required orbital reconstruction. Also, we accurately diagnosed orbital fracture with C.T., 3D model and good result for orbital reconstruction with sufficient parietal block bone graft during average 16.8 months follow-up.

Radio frequency coil which is capable of transmit and receive the signal has been used for image production in magnetic resonance imaging(MRI). Tuning and matching characteristic of radio frequency coil is major factor determining the image quality. In experiment the used coil was called a staircase type coil which is simplified the birdcage coil and referred to a simple LC resonant circuit. Because the inductance values of the coils are fixed coil performance was examined by changing of the capacitance values. In this study capacitance values were experimentally determined to increase of-tuning and matching effect in junction of the coil between coil endring and BNC cable to obtain the high quality of image.

Purpose: Teeth are generally exposed when people smiling. Moreover, the exposed teeth and soft tissue when smiling becomes an important guideline for esthetically prosthetic restoration. This research is to compare and find out differences of Korean young men's smile living in presence and twenty years ago. Materials and methods: Subjects, 100 young men (50 male and 50 female), were required about several aspects; normally developed physical condition, no psychological or genetic disorders, a fine face with no loss of teeth, no experience in orthodontic or prosthetic treatment, relatively normal occlusion, aged between 20 - 29. The photos of the subject at rest position and front face when fully smiled were taken three times. 100 photos (50 male and 50 female) were chosen at random from the 240 university students' smile photos taken by Yoon and his colleagues in 1991. By Hulsey's method of measuring smile, several factors; the change of upper lip curvature, the change of the relation between the upper lip and teeth, parallelism between Mx. incisor and lower lip, contact relation between Mx. incisor and lower lip and teeth displayed in a smile, were measured and analyzed. Meanwhile, ten dentists assessed aesthetic evaluation about men and women's smile for twice and recorded and compared smile score. The -test (P<.05) was used to compare the measured value. The difference of smile score was analyzed by t-test (P<.05). Results: The smile score calculated in 2011 (60.22) was higher than that of 1991 (52.80). Among five measurement categories, the noticeable difference was distinguished from two factors; the change of upper lip curvature and contact relation between Mx. incisor and lower lip. Conclusion: The Korean young men's smile has been considerably improved for twenty years. And it is found that the change of upper lip curvature plays an important role, that is, the smile formed with an ascended labial commissure has been increased significantly. 연구 목적: 일반적으로 치아는 미소 지을 때 가장 많이 노출되며, 미소 시에 나타나는 치아와 연조직과의 관계 등은 심미적인 보철 수복에 있어서 중요한 지침이 된다. 본 연구는 20년 전 한국 청년들의 미소와 현재 한국 청년들의 미소를 비교하여 그 차이를 알아보고자 하였다. 연구 재료 및 방법: 신체적인 발육 상태가 정상적이고 전신적 또는 유전적 질환이 없으며, 안모가 양호하고 치아의 결손이 없으며 교정 및 보철치료를 받은 경험이 없고, 교합상태가 비교적 정상적인 20 - 29세 사이의 청년 100명(남자 50명, 여자 50명)을 대상으로, Cephalometer에 사용되는 두부 고정 장치를 사용하여 피검자의 F-H plane이 지면에 평행하도록 한 후, 35 mm 카메라(400D. Cannon, Japan), 120 mm 렌즈 그리고 삼각대를 사용하여 피검자의 midsagittal plane에 카메라 렌즈의 중심을 맞추고 상악 중절치 절단과 렌즈와의 거리를 930 mm로 하여 안정위 및 full smile 시의 안모 정면 사진을 3회씩 촬영하였다. 1991년 윤 등이 촬영한 대학생 240명 중 무작위로 선택한 100명(남자 50명, 여 자 50명)의 미소사진과 함께 개인용 컴퓨터 및 V-ceph 6.0 프로그램을 이용하고 Hulsey의 미소 계측 방법을 참고로 하여, 상순의 형태, 상순과 치아와의 관계, 하순과 상악 전치 절단연과의 평행 관계, 하순과 상악 전치 절단연과의 접촉 관계, 미소시 나타나는 치아 등을 계측하고 분석하였다. 한편 치과의사 10인이 남,녀 각 2회씩 미소에 대한 미적 평가를 시행하여 미소평점을 기록하고 비교하였다. 결과: 지난 20년간 한국 청년의 미소가 크게 향상되었으며 이러한 변화는 주로 상순의 형태가 영향을 준 것을 알 수 있었다. 즉 입꼬리가 위로 올라가는 형태의 미소가 괄목할 만한 증가를 보인 반면 입 꼬리가 아래로 처지는 형태의 미소는 현저한 감소를 보였다. 결론: 지난 20년간 한국 청년의 미소가 크게 향상되었는데 이러한 변화는 주로 상순의 형태가 영향을 준 것으로 나타났다.

後期飼料를 3주령부터 조기에 급여한 9주령 Hubbad鷄肉의 3부위 근육을 공시육으로 하여 4℃에서 저장하면서 경시적(도살직후 저장후 2일 4일 7일)으로 지질의 함량을 추출하고 지방산의 조성을 GLC로 분석한 결과 다음과 같은 결과를 얻었다. 1. 지질함량은 도살직후 대퇴부위가 2.67%로 가장 높고 흉심부가 2.38%, 근위 1.28% 가장 낮았으며, 저장기간에 따른 지질함량의 변화는 3부위 모두 저장기간의 경과에 따라 지질함량이 감소하였다. 2. GLC로 분석한 지방산은 3부위 모두 myristic acid(14:0)로 부터 arachidonic acid(20:4)까지 10種을 분리 동정하였다. 3. 함량이 제일 높은 지방산은 세부위 모두 불포화 지방산인 Oleic acid로 40.7~45.5%였고 다음 Palmitic acid로 20.5~27.9%였으며 linoleic acid는 6.9~18.3%로 타육류에 비해 필수지방산인 linoleic acid의 함량이 높았다. 4. 3部位 모두 저장시간이 경과함에 따라 포화지방산의 함량이 증가되고 불포화지방산의 함량은 상대적으로 감소되었다. The meat cut 3 parts of leg, breast and gizzard of broiler-Hubbard at 9 weeks fed early finisher diet from 3 weeks were stored at 4℃ for four levels, immediately after slaughtering, 2 days, 4 days and 7 days after storing in order to extract lipid contents and fatty acid compositions was analyzed by the GLC method. The results obtained in this experiment were summarized as follows: 1. Lipid contents were the highest with 2.67% in the leg immediately after slaughtering and the lowest, with 1.28% in the gizzard. Fatty acid compositions were decreased in all the three parts as the storage time passed. 2. Ten fatty acids from myristic acid(14:0) to arachidonic acid(20:4) in all the there parts were identified by GLC. 3. The highest fatty acid was oleic acid with 40.7 to 45.5% and the next, palmitic acid with 20.5 to 27.9%. Linoleic acid was higher with 6.9 to 18.3% in broiler-Hubbard then in the other broiler. 4. As the storage time passed, saturation fatty acid increased and unsaturation fatty acid decreased relatively.

유럽안보체제의 변화의 쟁점 : EU의 공동외교안보정책(CFSP) 분석을 중심으로 An Analysis on Europea Union's CFSP

From the signing of the Treaties of Rome on 25th March 1957, the Europeans focussed especially on economic aspects, i.e. the creation of a common market. But even if the ideas for cooperation in the area of international policy and security were already in evidence, during nearly forty years, the concept 'common foreign policy' found no place in the many treaties. Although the Member States of the EC(European Community) cooperated to consult one another on major international policy and security problems from later 1970, this was at intergovernmental level in the context of 'EPC'(European political cooperation). But the Europeans formalized the intergovernmental cooperation by singing the SEA(Single European Act) in 1986 without any changes of its nature or methods of operation. The treaty of Maastricht changed a lot the way of cooperation of the Europeans for the first time. Since the Treaty's entry into force on 1 November 1993, the 'CFSP'(Common Foreign and Security Policy) let the Europeans cooperate in the field of the problems of defense of Europe, international and European armed conflicts, human rights and any other subject linked to the fundamental principles and common values of the European Union. The provisions on the CFSP were revised by the Amsterdam Treaty, which came into force on 1 May 1999, and the Treaty of Nice, signed on 26 February 2001 renewed CFSP provisions. In the long run, since the end of the Cold War, Europe's defence needs have changed, and the EU has decided to take responsibility for its own security. Therefore, an analysis on European Union it self, the success of the formation of the CFSP and the works of multilateral institutions of EU gives a great importance for studying the regional multilateral security system, as a new regional security Regime. In this sense, this paper treats the changes of security environment in Europe, the process of building of the CFSP, the problems of its execution, European security identity, NATO and EU's enlargement and security problems.

A common form of relapse in adenocarcinoma of the stomach is intraperitoneal dissemination, in fact, among gastric adenocarcinoma patients who have undergone surgery intended to cure, approximately 50% of the patients develope initial recurrence in the peritoneal cavity regardless of the anatomic site of the primary tumor within the stomach. The efficacy of systemic postoperative chemotherapy to prevent peritoneal recurrence of gastrric adcnocarcinoma is not satisfactory. There is still a great need for improved therapeutic strategies on the disseminated microscopic disease and small miliary nodules remaining on the peritoneal surface or lymphatics after operation. The authers have made fluorouracil-polyglycolic acid composite disks(Fu-PGA disks) with fluorouracil and biodegradable polymer: polyglycolic acid for more effective intraperitoneal chemotherapy. We inserted the Fu-PGA disk(s) in the peritoneal cavity of rat and pharmacokinetic study was performed to measure fluorouracil concentration in the peritoneal fluid, plasma, liver, kidney and heart tissue at 24 hour, 72 hour and 168 hour after insertion of Fu-PGA disk(s). Myelosuppressive action of this composite also was determined following its administration. The data of this study suggested that Fu-PGA composite will be a new device releasing drugs in a controlled manner and having targetability to peritoneum, and this device will be improving the efficacy of intraperitoneal chemotherapy for gastric adenocarcinoma.

완전뇌허혈후 재관류시에 국소뇌혈류, 체성감각유발전위 및 신경학적 회복에 대한 Mannitol과 Thiopental의 효과

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.
