교정치료 후 연조직의 변화가 나타난다. 특히, 하안면부위에 많은 변화를 일으키게 되며, 대표적으로 입술은 치아 이동량의 $60\~70\%$정도 이동한다고 알려져 있다. 하지만, 이동량은 개인마다 그 양상이 다양하다. 본 연구는 환자의 입술두께에 따라 연조직 이동 양상에 차이가 있는지 여부를 조사하는데 그 목적이 있다. 발치를 동반한 교정치료를 받은 성인환자를 대상으로 basic upper lip thickness에 따라 환자를 분류한 결과, 두께가 얇은 군(group 1)에서 치료 후 연조직 변화에 영향을 미치는 요인으로는 mentolabial angle와 하순의 변화간에 음의 상관관계를 보였다. 두께가 평균인 군(group 2)에서 상순의 변화에 영향을 미치는 요소로는 상악전치의 변화, 하악전치의 변화, 하순의 변화, nasolabial angle의 변화로 나타났으며, 하순의 변화에 영향을 미치는 요소로는 상순의 변화, 상악전치의 변화, 하악전치의 변화로 나타났다. 두께가 두꺼운 군(group 3)에서 는 상순, 하순의 변화는 전치위치의 변화나 연조직 변화와는 관련 없음으로 관찰되었다.

Background: Diagnosis procedure combination (DPC) has recently been introduced in Korea as a demonstration project and it has aimed the improvement of accuracy in bundled payment instead of Diagnosis related group (DRG). The purpose of this study is to investigate that the model of end-stage liver disease (MELD) score as the severity classification of liver diseases is adequate for improving reimbursement of DPC. Methods: The subjects of this study were 329 patients of liver disease (Korean DRG ver. 3.2 H603) who had discharged from National Health Insurance Corporation Ilsan Hospital which is target hospital of DPC demonstration project, between January 1, 2007 and July 31, 2010. We tested the cost differences by severity classifications which were DRG severity classification and clinical severity classification-MELD score. We used a multiple regression model to find the impacts of severity on total medical cost controlling for demographic factor and characteristics of medical services. The within group homogeneity of cost were measured by calculating the coefficient of variation and extremal quotient. Results: This study investigates the relationship between medical costs and other variables especially severity classifications of liver disease. Length of stay has strong effect on medical costs and other characteristics of patients or episode also effect on medical costs. MELD score for severity classification explained the variation of costs more than DRG severity classification. Conclusion: The accuracy of DRG based payment might be improved by using various clinical data collected by clinical situations but it should have objectivity with considering availability. Adequate compensation for severity should be considered mainly in DRG based payment. Disease specific severity classification would be an alternative like MELD score for liver diseases.

Object : To treat hydrocephalus by ventriculo-peritoneal shunt operation, the correct positioning of the proximal catheter in the ventricle is very important. The purpose of this study was to develop the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle in the ventriculo-peritoneal shunt operation. Materials and Methods: The "shunt guiding kit" is made of tungsten alloy and it consists of one frame, two screws and one guider. Through the guider, the proximal shunt catheter operates by mechanically coupling the posterior burr hole to the anterior target point. Results: We have treated three hydrocephalus patients with use of the "shunt guiding kit", and achieved good location of proximal shunt catheters. Conclusion: We developed the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle, and this would be very useful for preventing ventriculo-peritoneal shunt malfunction and preventing possible brain injury during the procedures.

Purpose: This study was performed retrospectively and to compare the clinical outcomes of the surgical management using Antiglide plating and lateral plating for Danis-Weber type B isolated lateral malleolar fractures. Materials and Methods: Between March 2004 and March 2009, 92 patients were followed up for more than 6 months after surgical treatment. 49 patients were treated with Antiglide plating, whereas the remaining 43 patients underwent lateral plating. The results of the two groups were analyzed both radiographically and clinically using Ankle scoring system. Results: Both groups were comparable for age, sex distribution, time to surgery, and operation time. Bone union was noted at average of 8 weeks in all fractures. The mean ankle score was similar in both groups (94% versus 93%). Conclusion: Antiglide plating for Danis-Weber type B isolated lateral malleolar fracture is one of the good methods which has some advantages such as early ankle motion, ambulation and smaller operative incision.

Hyperbaric oxygen therapy(HBO) is defined as breathing 100% oxygen while in an enclosed system pressurized to greater than on atmosphere(sea level). This increased oxygen delivery furthers your body's ability to kill germs and to increase healing. HBO is a supplemental therapy to be used in addition to the current medical and surgical therapy you are receiving. HBO typically is used to complement treatments of medical problems such as bone infections, complication of radiotherapy, and certain chronic, non-healing wounds. On an emergency basis, the chamber also is used to treat problems such as carbon monoxide poisoning and the decompression sickness. We analysed stastically cases which are treated by hyperbaric oxygen therapy in point of oral and maxillofacial region on the Kangnam General Hospital for aid in comprehension and application of this therapy. Total 760 patients were treated at Gangnam General Hospital from July 1996 to September 1999. They were classified by region to Decompression sickness(DCS), Carbon monoxide poisoning(CO), General surgery(GS), Orthopedics(OS), Oral and Maxillofacial surgery(OMFS), others. Patients of Oral and Maxillofacial surgery were divided by diseses to Osteomyelitis, Osteoradionecrosis, Reconstruction, Bone graft, Difficult wounds, others. The results were as follows. 1. This institute conducts HBO therapy for DCS which takes up 62% and 10.5% for OMF region. 2. In OMF region, Osteomyelitis is 40%, Osteoradionecrosis is next, Bone graft, and Reconstruction is a row. 3. According to our precious study, HBO has been frequently conducted in OMF region compared to past, however, it is less actively conducted in this area for research than other conturies. Therefore, We need further application to the clinical use.

Sixty-two medical records of patients with coal workers' pneumoconiosis who died in hospital as coal workers' pneumoconiosis were analysed for study of the relationship between forced expiratory volume in one second ($FEV_1$) and life expectancy in coal workers'pneumoconiosis. In the group who died of asphyxia from hemoptysis, life expectancy were well fitted with $FEV_1$(p<0.05). But others were not well fitted to simple linear regression equation. The prevalence of ECG sign of col pulmonale was more in the group of cardiorespiratory failure than asphyxia group. So, in the case of far advanced cor pulmonale, it was difficult to predict life expectancy by simple linear regression equation

Background: Most clinical studies of immune responses activated by Korean Red Ginseng (KRG) have been conducted exclusively in patients. However, there is still a lack of clinical research on immune-boosting benefits of KRG for healthy persons. This study aims to confirm how KRG boosts the immune system of healthy subjects. Methods: A total of 100 healthy adult subjects were randomly divided into two groups that took either a 2 g KRG tablet or a placebo per day for 8 weeks. The primary efficacy evaluation variables included changes in T cells, B cells, and white blood cells (WBCs) before and after eight weeks of KRG ingestion. Cytokines (TNF-α, INF-γ, IL-2 and IL-4), WBC differential count, and incidence of colds were measured in the secondary efficacy evaluation variables. Safety evaluation variables were used to identify changes in laboratory test results that incorporated adverse reactions, vital signs, hematological tests, blood chemistry tests, and urinalysis. Results: Compared to the placebo group, the KRG intake group showed a significant increase in the number of T cells (CD3) and its subtypes (CD4 and CD8), B cells, and the WBC count before and after eight weeks of the intake. There were no clinically significant adverse reactions or other notable results in the safety evaluation factors observed. Conclusion: This study has proven through its eight-week intake test and subsequent analysis that KRG boosts the immune system through an increase in T cells, B cells, and WBCs, and that it is safe according to the study's safety evaluation.
