The present study was performed to evaluate the function of the mandible according to the pattern of fracture and treatment methods of condylar fractures of the mandible and help operators in making a treatment plan. Sixty patients (average follow-up period was $7.8{\pm}9.4$ months) who were treated for condylar fracture from June, 2002 to May, 2006 at the Department of Oral and Maxillofacial surgery, Chonnam National University Hospital were reviewed. The common causes of the condylar fracture were traffic accident and fall-down (35.0%). In concomitant injuries, laceration was 46.7% and the fracture of the mandibular symphysis was highest incidence (60.0%). The common site of the fracture was the condylar head (47.8%), followed by subcondyle (36.2%) and condylar neck (15.9%). Under 15 years old patients, the closed reduction was performed in 87.5% out of the patients. All of the condylar fragments were fixed to the mandible with titanium miniplates in cases of open reduction. The mean period of intermaxillary fixation (IMF) was $14.2{\pm}6.5$ days in closed reduction and $10.0{\pm}4.2$ days in open reduction. The old patient with bilateral condylar head fractures, who were treated by closed reduction with IMF for 3 weeks, showed the limitation of mandibular movements. But, there was no significant different results between open reduction and closed reduction with the respect of the Helkimo's mandibular mobility index and clinical dysfunction index (DI). Complications, such as fibrous ankylosis and resorption of the mandibular condyle, were not observed in all patients. These results suggest that the good results can be obtained by closed reduction with proper IMF periods and functional exercise in most condylar fractures of the mandible except severely displaced extracapsular fractures.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation and results from environmental factors and genetic factors. Although cigarette smoking is a major risk factor, other environmental exposures can influence COPD. The purpose of this study is to investigate the clinical characteristics of COPD according to the history of environmental exposure. Methods: The study population comprised of 347 subjects with COPD who were recruited from the pulmonary clinics of 14 hospitals within the Korean Obstructive Lung Disease Study Group. We classified environmental exposures according to history of living near factory, and direct exposure history to firewood or briquette. According to living environmental exposures, we compared the frequency of respiratory symptoms, pulmonary function, quality of life, exercise capacity, and computed tomography phenotypes. Results: Thirty-one subjects (8.9%) had history of living near factory, 271 (78.3%) had exposure history to briquette, and 184 (53.3%) had exposure history to firewood. Patients with history of living near a factory had a significantly longer duration of sputum, while patients with exposure to firewood tended to have lower forced expiratory volume in one second, and patients with exposure to briquette tended to have lower six minute walk distance. Conclusion: COPD subjects with the history of living near factory had more frequent respiratory symptoms such as sputum. Our data suggest that environmental exposure may influence clinical phenotype of COPD.

This study was designed out to develop a home health care service for nurses working in community care services. This study investigates actual conditions at welfare institutions related to health needs the demands of clients, and the state of home health care services we hope that this study will improve upon the current service system. In Korea home health care services are still developing and only new becoming a part of the health care supply system. The data was collected by recording the client home nursing assessments modified to the situation of UTMB home health agency. In this study 107 clients were selected for home care who needed care for physical and mental deficits. The study lasted from March to November of 1995 at one of the welfare service institutions in Chunchon city. The results show that those who most frequently needed care services were over 50 years old with a health deficit of 80.3%, followed by sex as women who needed care at 59.8%. 50.5% of the clients had very little education. 99.1% of the clients live with their family, and a medical diagnostic analysis reveals that 73.9% of the 5 year period of illnesses were the following : 38.8% - muscular -skeleton system disorder, 24.4% - hypertension and stroke, 25.7% sole disease of arthritis. For behavioral conditions 43.3% of the patients were without care services, 56.6% of the patients were taking treatment that 73.5% of those were taking medication. The most main complaint of patients were 22.4% of pain in the extremities, next were 16.8% of a limitation of body activities, 15.0% was lumbo-sacralgia. According to the investigator who was a senior student nurse, the following suggestions were made: 32.7% for curative medical services, 29.9% for physical exercise, 19.6% for emotional support. Consultation nursing services consisted of 67.2% for physical therapy, 11.2% for the maintaining healing, 9.4% for counseling. The patients at home, required assistance most frequently for muscular-skeleton problems under the category of physical systems (33.3%). But, on the other hand, 49.5% of the patients required care givers at home, 28.2% had a knowledge deficit, 21.0% had malnutrition, 18.4% had bad impaired communication. The character of health problems were devided into chronic disease(67.0%), accidents(I3.1%), and general disease(15.9%). 86% of the disabled client had an impairment of the physical system. Eating (86.9%) , Toileting(77.6%), and personal care showed much the same of ADL condition, the level and range of achievement of mobility, the most frequently self performed was 81.3% only in a room size area, and 40.2% were completely dependent when going out. Although there were a large number of home care services in th community at these welfare institutions, many clients needed a variety of curative services. As policy changes have gathered momentum, responsibility for the development of a more suitable program was demanded by the clients from the community.

Cerebral palsy(CP) is one of the most common motor disease, due to brain injury during fetal and neonatal development which results in neuromotor paralysis and associated neuromuscular symptoms. Features of CP include motor disability due to the lack of muscle control, often accompanied by sensory disorders, mental retardation, speech disorders, hearing loss, epilepsy, behavior disorders, etc. There are increasing chances of treatment of dental patients with cerebral palsy, as the occurrence of CP is increasing with the decrease in infant mortality and an increase in immature birth and premature birth and also, there is a trend to pursue of higher quality of life. Reports on the relationship between CP and maxillofacial deformity are uncommon, but it is well known that the unbalance and discontrol of the facial muscles, lip, tongue and the jaws leads to malocclusion and temporomandibular joint disorders, and statistics show that class 2 relationship of the jaws and open bite is frequently reported. However, it is difficult to perform maxillofacial deformity treatment, which consists of orthodontic treatment, maxillofacial surgery and muscle adaptation training, due to difficulties in communication and problems of muscle adaptation caused by difficulties in motor control which leads to a high recurrence rate. This case report is to trearment of maxillofacial deformity in CP patient. A 26 year old female patient came to the department with the chief complaint of prognathism of the mandible and facial asymmetry. According to the past medical history, she was diagnosed as cerebral palsy 1 week after birth, classified as GMFC, classII accompanied with left side torticollis. The patient's intelligence was moderate, and there were no serious problems in communication. For two years time, the patient underwent lingual frenectomy, pre-operation orthodontic treatment and then bimaxillary orthognathic surgery to treat mandibular prognathism and facial asymmetry followed by rehabilitatory exercise of facial muscle. After 6 months of follow up, there was a good result. This is to report to the typical signs and symptoms of DFD in CP patient and the limitation of the usual method of the treatment of DFD in CP patient with literature review.

만성 폐쇄성 폐질환은 비가역적, 점진적 기도 폐쇄가 특징인 주요 사망 원인중의 하나이다. 말기 폐쇄성 폐질환 환자는 다양한 신체적, 정서적, 사회적, 기능적 문제로 인해 호스피스 완화의료가 필요하다. 따라서, 완화의료의 목적은 증상 조절, 운동 능력 및 삶의 질 향상이며, 아울러 급성 악화 빈도를 줄이고 질병의 진행을 늦추는 효과를 기대할 수 있다. 다양한 진행 과정 때문에 말기 시점을 예측하기 어렵다. 호흡곤란 정도, 폐기능, 혈액학적 임상 지표를 이용하여 대상자를 선정하는 기준을 마련하고 적용시점을 논의해야 한다. 질환의 특성상 진단 후 초기에는 완치 목적의 치료가 중심이 되어 완화의료가 이를 보완하는 방식으로 적용되다가, 완치 목적의 치료를 위해 입 퇴원을 반복하거나 치료의 반응이 낮고 나쁜 예후가 예상될 때 완화의료 비중이 확대되는 것이 바람직하겠다. 폐쇄성 폐질환 환자에게 적극적으로 호흡재활을 적용하고, 환자의 의사결정을 존중하여 증상 악화 이전에 미리 대책을 마련하고 앞으로의 치료 목표를 논의하기 위한 완화의료 팀을 구성하고, 국내 현실에 맞는 진료 연계 체계를 마련하는 것이 필요하다. 제도가 잘 정착하기 위해서는 일차 의료 및 암환자 대상의 완화의료 전문 팀과의 협업이 중요하며, 우선 고려되어야 할 것이다.

Reserved forces of ROKA are in charge of replacement of TOE in the wartime and mission of rear area operation. But there is institutional inertia in the law and organization oriented to fill human resources rather than take mission. We need to prepare for the investment and arrangement of reserved forces as military power that would be replaced standing forces. In this portion, to reinforce reserve forces elite, First, efficient mobilization regulations and systems are suggested. I covered a maintenance of relevant mobilization ordinances which need to legislated and approved by national assembly for wartime and development of mobilization system which might lose the appropriate time for mobilization due to complicated declaration procedures and measures to overcome the panic at the initial stage of the war and organization and employment of nationwide transportation system and mobilization center. To ensure efficient resource management and mobilization of reserve forces with a number of approximately 3 million, there's a necessity of organization for integration and conciliation. To make it real, I suggested establishing and employing the mobilization center, on first phase, employ the mobilization center focusing on homeland divisions, on second phase, it is advisable to convert to national level mobilization system and develop to central mobilization center focusing on national emergency planning committee. During peacetime, in conjunction with Mobilization Cell, mobilization center can conduct resource survey and integrate and manage mobilization resources and take charge of mobilization training of subordinate units, and during wartime, in conjunction with mobilization coordination team and Cell, can ensure the execution of mobilization. Second, Future oriented reserve forces management system such as service system of reserve forces and support system of homeland defense operations. Current service and trainings of reserve forces by the year have very low connection, as it is very complex to manage the resources and trainings, and service and training lack the equity, re-establishment of service system is required. Also in an aspect of CSS and cultivation support for reserve forces, as the scope and limitation of responsibility between the armed forces and autonomous organization is obscure, conditions to conduct actual-fighting exercises are limited. Concentrated budgetting is extremely difficult because reserve forces training fields are scattered nationwide, and facilities and equipments are rapidly getting older. To improve all these, I suggest the organization of homeland defense battalion with a unit of "City-Gun-District" and supporting the local reserve forces. Conduct unit replacement or personal replacement for those who have finished their 1 or 2 years and homeland defense operation duty for those with 3-5 years for consistency and simplification. Third, I suggest Future oriented Reserved Training(FRT) and Training Center oriented training management to establish a reliable reserve training. Reserves carry out expansion of unit, conventional combat mission, homeland defense and logistics support during wartime, and actual-fighting exercise, and disaster relief, peace keeping activities. Despite diverse activities and roles, their training condition still stays definitely poor. For these reasons, Modernization of weapons and facilities through gradual replacement and procurement is essential to enhance mobilization support system.
