It is well known that the postoperative skeletal instability after Le Fort I osteotomy for advancement of maxilla in the cleft patients is one of the major surgical problems. So we had tried to compare the amount of relapse after Le Fort I advancement surgery in the horizontal and vertical positional change, angular change of reference points between cleft patients and non-cleft patients. Longitudinal records of 10 consecutive cleft patients (test group) and 20 non-cleft patients (control group) were analyzed. Lateral cephalograms were taken preoperatively, immediately postoperatively, and 2, 6, 12 months postoperatively. We measured horizontal and vertical changes (ANS, PNS, AI) and angular change (SNA) of the reference points and lines. In the test group, horizontal relapse of ANS, PNS, AI point are 36.4%, 37.5%, 32.0% respectively at 12 months postoperatively. The vertical relapse of ANS, PNS, AI are 25.3%, 32.3%, 39.1% respectively at 12 months postoperatively. The angular change of SNA is 33.6% at 12 months postoperatively. In the control group, horizontal relapse of ANS, PNS, AI point are 23.8%, 30.2%, 21.7% respectively at 12 months postoperatively. The vertical relapse of ANS, PNS, AI are 22.7%, 27.3%, 25.1% respectively at 12 months postoperatively. The angular change of SNA is 22.2% at 12 months postoperatively. The cleft patients have a larger tendency of skeletal and dental relapse compared with non-cleft patients after Le Fort I surgery. So the oral and maxillofacial surgeons must keep in mind these facts in order to minimize the relapse phenomenon from the beginning of surgical planning to postoperative care.

Objectives : The aim of this study is to evaluate the sequential metabolic changes in experimental hydrocephalus and the clinical applicability to the diagnosis and prognosis of hydrocephalus using proton MR spectroscopy. Methods : Hydrocephalus was experimentally induced in 30 cats(2-3kg body weight) by injecting 1ml of sterile kaolin suspension(250mg/ml) into the cisterna magna. Proton MRS was performed with a 1.5 T MRI/MRS unit (Vision Plus, Siemens) at pre-treatment and at 1, 3, 7, 14, 21, and 28 days after the kaolin injection. PRESS(TR/TE=1500/270msec) technique was employed. The major metabolites which include N-acetyl aspartate (NAA), creatine(Cr), choline(Cho), and lactate(Lac) were quantitatively analyzed and the relative concentrations ratios were evaluated. Multislice $T_2$-weighted images were also obtained using fast spin echo sequence(TR/TE= 2500/96msec) to monitor the morphologic changes along with progression of hydrocephalus. Results : Hydrocephalus was successfully induced in all 30 cats. Twenty five cats died within 3 days and one at the end of the second week. In all animals, the NAA/Cr ratios initially decreased during the acute stage. In 4 surviving cats, the NAA/Cr ratios initially decreased during the acute stage(<14 days) and then gradually increased to the prekaolin level as follows : pre-kaolin($1.49{\pm}0.04$), day 1($1.11{\pm}0.07$), day 7($1.17{\pm}0.04$), day 14($1.40{\pm}0.03$), day 21 ($1.46{\pm}0.06$), day 28($1.43{\pm}0.03$). These levels were relatively well correlated with the symptomatologic improvement. Lactate peak, which reflects the evidence of ischemia, did not appear throughout the entire period except in one case which expired at the end of the second week. Conclusions : The NAA/Cr ratio of the sequential proton MRS in kaolin-induced hydrocephalic cats reflects a metabolic aspect of the hydrocephalus at each stage. A decreased NAA level at the early stage is from both neuronal and axonal damage which may provide diagnostic information in the acute stage of hydrocephalus. In addition, the initial fall of NAA/Cr ratio and recovery in the late stage, when no lactate peak emerges, may suggest that the main insult of the parenchyma is not to the neuron itself but to the axon, which may be related to a good prognosis. However, emergence of the lactate peak and unrecoverable NAA/Cr at the end of the acute phase may be a poor prognostic factor. In the chronic stage, recovery of NAA/Cr ratio may provide a diagnostic clue for the differentiation between hydrocephalus and cortical atrophy.

Purpose: To evaluate the effectiveness of the Quickert-Rathbun suture to correct involutional entropion. Methods: A retrospective review was performed of 132 consecutive patients (132 lids, male 58, female 74) with involutional entropion who underwent correction from September 2001 to June 2004 at Kim`s eye hospital. All surgical corrections were performed with the Quickert-Rathbun suture technique. The average follow-up period was 9 months (1~17 months). Results: The average length of follow-up time was 14 months (6~22 months). There were no long-term complications like lagophthalmos or ectropion. Surgery was successful in 102 (77.2%) of the 132 eyelids in the first Quickert-Rathbun suture. The second Quickert-Rathbun suture was performed to 17 out of 30 recurred patients, One of whom was noted to have recurrent entropion at 12 months. The final success rate of Quickert-Rathbun suture was 89.3%. The average length of recurrence time was 9.1±8.4 months. Conclusions: The Quickert-Rathbun suture described is simple, straightforward and reliable for the correction of involutional entropion primarily.

Objective : The aim of this study is to evaluate clinical outcome of anterior screw fixation for type II odontoid fractures for the prliematim of atlanatoaxial mobility. Methods : Between 1995 and 1999, we treated 15 cases of type II odontoid fractures by anterior screw fixation among 44 cases of odontoid fractures. Thece included 14 males and 1 female aged from 23 to 63 years, with a mean age of 39.7 years. The causes of trauma were traffic accident in 13 cases, slip down in 1 and fall down in 1. The fracture type was type II-P in 7 cases, type II-A in 3, type II-N in 2 and type II-A and P in 3. The fracture line was oblique downward and backward in 6 cases, oblique downward and forward in 3 and horizontally in 6. The range of follow up was 4 to 47 months(mean 26.5 months). Results : Adequate reduction and fixation were obtained in 12 cases. Three cases in which fracture type and line were type II-A and oblique downward forward were failed, so posterior transarticular screw fixation was performed. All except 3 failed cases had adequate cervical movement and stability. There were no operative mortality nor morbidity. Conclusion : Anterior screw fixation provides the best anatomical and functional results for type II odontoid fracture with intact transverse ligament when fracture line is horizontal or oblique downward and backward. But it is limited when fracture line is oblique downward and forward.

본 연구에서는 중앙정부가 추진하는 스마트시티 정책에서 경기도 광역자치단체의 역할을 알아보고자 한다. 이를 위해 중앙정부 중심으로 추진되고 있는 스마트시티 정책 사업에 도내 기초지자체의 참여현황을 파악해보고 특성을 도출하여 경기도 광역자치단체가 마련해야 하는 세부과제를 제시한다. 현재 경기도 지역은 U-City 이후에 도내 기초지자체가 제도적 기반을 마련하고 중앙정부 스마트시티 정책사업에 참여하고 있다. 경기도 광역자치단체는 2020년에 스마트시티 관련 조례를 제정하고 스마트도시 지방자치단체 협의회에 참가하는 정도이다. 향후 경기도는 법 개정을 건의하여 스마트시티 정책추진의 동력을 확보하고 경기도만의 거버넌스를 확립하여 효율적인 정책추진을 위한 체계마련을 고민한다. 또한 중앙정부 스마트시티 정책사업에 "광역자치단체 모델의 통합플랫폼 구축사업" 참여를 검토하여 재난 안전상황에 효율적으로 대응할 수 있는 시스템을 마련하고, 정책의 사각지대를 중심으로 경기도 독자적인 스마트시티 정책추진을 검토해본다. The purpose of this study is to investigate the role of Gyeonggi provincial governments in smart city policy. In order to satisfy the purpose of the study, we closely identified how may local governments(si. gun) have been taking participated in smart city project of the central government, and its characteristics. Then we know the detailed strategies that Gyeonggi provincial governments should do. Gyeonggi-do provincial governments enacted smart city-related ordinances in 2020 and participated in the Smart City Local Council. In the future, Gyeonggi privincial government will propose amendments to the law, review participation in the central government smart city policy project, the "integrated platform construction project of the metropolitan government model", and propel Gyeonggi-do's own smart city policy based on the blind spots of the policy.

CONTOUR RECONSTRUCTION OF FACIAL DEFECT WITH SPLIT STERNOCLEIDOMASTOID MUSCULAR FLAP FOLLOWING PAROTIDECTOMY

Various muscular flaps are used in oral and maxillofacial reconstructive surgery for the defects caused by tumor resection and trauma or for the correction of head and neck deformities. The sternocleidomastoid(SCM) muscle may be widely used as a muscular or myocutaneous flap in these lesion. The authors used SCM muscular flap for the expected parotid defect following benign tumor related conservative parotidectomy in three cases. We expected that prevention of post-operative facial deformity, reduction of dead-space and protection of denuded facial nerve etc. is lead by SCM muscular flap. But the total SCM flap can lead to some complications such as "flat neck deformity", limitation of neck movement and overcontouring of parotid defect. Therefore, the authors used split pedicled SCM muscular flap and it lead good favorable results of post-operative functional and esthetic problems.

FIBRIN SEALANTS IN MAXILLOFACIAL SURGERY : A INTRODUCTORY REPORT

김명진,박형국,Kim, Myung-Jin,Park, Hyung-Kook Korean Association of Maxillofacial Plastic and Re 1991 Maxillofacial Plastic Reconstructive Surgery Vol.13 No.2

The fibrin sealant was first designed as an alternative to surgical suture for the purpose of surface-to-surface union especially in parenchymal organs like the liver, spleen and kidney. The clinical application of currently used fibrin sealant was first introduced in 1972. The fibrin sealant consists of principal two components; lyophilized human fibrinogen and bovine thrombin. The fibrinogen component also contains coagulation factor XIII. A solution of aprotinin, an inhibitor of fibrinolysis is used to dissolve the fibrinogen and to provide the first component, and a solution of calcium chloride is also used to provide the second component. From July to December in 1990, during 6 months, we used fibrin sealant in the 28 patients of 33 various cases, in the following ways; supportive application of fibrin sealant after free autogenouse nerve graft for the repair of inferior alveolar nerve, facial nerve or accessory nerve, treament of hemangioma or lymphangioma to thrombosize and lead to the tumor shrinking, skin grafting to stimulate the adhesion and tissue repair, bone grafting in the patients of cleft alveolus, mandibular reconstruction or orthognathic surgery to facilitate the knitting of bone chips, tissue adhesion after tumor resection, radical neck dissection or flap reconstructions, and supportive adhesion of external auditory cannal after TMJ surgery via postauricular approach. No adverse effects were observed, none of the patients developed hepatitis or other blood transmitted disease, and the wound healing were acceptable.

연구 목적 : 구취의 주된 화학적 요소는 휘발성 황 화합물 (VSCs)들이다. 이들은 치태, 설태, 타액과 혈액, 상피세포의 혐기성 그람 음성 세균에 의한 단백분해 변성으로 만들어 진다. 또한 구취는 치주질환과 타액내의 세균의 증가를 야기하는 불량한 구강 위생상태에서 기인한다고 보고되고 있다. 이 연구의 목적은 VSCs를 측정함으로 구취에 대한 비외과적 치주 치료의 영향을 평가하고, 타액내의 세균 수를 측정함으로써 VSCs와의 상관관계를 살펴보고자 하는 것이다. 연구 대상 및 방법 : 중등도의 만성치주염을 가지는 23명의 참가자들이 대조군과 실험군으로 분류되었다. 대조군은 구강위생교육 (치간청결기구와 혀세정 포함)만을 시행하였고 실험군은 구강위생교육과 함께 24시간 내에 전악 치석제거술과 치근활택술을 시행하였다. 치료 전과 치료 4주 후에 VSCs 농도를 $Halimeter^{(R)}$(Interscan Corp., CA, USA)를 사용하여 측정하였고 타액 시료는 혐기성과 호기성 조건에서 배양되었다. 결과 : 4주 후에 두 군 모두에서 휘발성 황화합물의 농도가 유의하게 감소하였고, 실험군에서의 감소량이 통계적으로 유의하게 더 크게 나타났다. 타액 내 세균의 배양에서 총세균수에 대한 혐기성 세균의 비율이 실험군에서만 통계적으로 유의하게 감소하였다. 그러나 세균의 비율과 휘발성 황화합물의 농도와의 상관관계는 낮게 나타났다. 즉 구취의 감소는 타액 요인 보다는 치주치료에 의한 다른 복합적인 인자의 작용에 의한 것으로 추론할 수 있었다. 결론 : 본 연구는 중등도의 치주염환자에서 구강위생교육만으로도 구취의 주요 화학적 요인인 휘발성 황화합물의 농도를 감소시킬 수 있으나 비외과적 치주치료를 동반하였을 때 더욱 큰 효과를 얻을 수 있는 것으로 해석된다. 그러나 실험 참가자의 수가 적었고 장기간의 분석이 이루어지지 않았으므로 앞으로 더 많은 연구가 구취에 대한 치주치료의 영향을 이해하기 위해서 필요할 것으로 사료된다.

김명진,양혜진,홍덕균,Kim, Myung-Jin,Yang, Hye-Jin,Hong, Duk-Geun 대한방사선방어학회 2011 방사선방어학회지 Vol.36 No.2

OSL dating for three hearths having the sequence of use and discard in No. 29 and 29-1 dwelling sites at Sogol cultural site was carried out. Resulting from the deconvolution of natural CW-OSL decay curve and thermal zeroing test, it was turned out that OSL signal was entirely composed of the heat- and light-sensitive fast component with high photoionization cross-section and all quartz OSL signals were thermally bleached under $300^{\circ}C$ which is the minimum temperature related to heating and cooking in Bronze age. After dose recovery test and plateau test, paleodose of each hearth sample was evaluated by using SAR method, and OSL age was determined from the ratio of paleodose to annual dose rate. For the purpose of the precision improvement of OSL age, Bayesian statistics was applied to each hearth's age and the archaeological sequence information. Finally, it could be concluded to the accurate use period of each hearth from the resultant OSL ages.
