The purpose of this study was to find out how the combined exercise program has an influence on the physical recovery of the patients suffering from work-related back problems. Research objects consist of 43 patients suffering from back problems due to workplace accidents. The result of the study shows that the combined exercise program increased muscular strength and endurance significantly and worked positively in lumbar recovery of the patients. It also increased the lowered flexibility caused by back pain to the level of normal state. In addition, the program was effective on the correction of the bad pose of body and scoliosis. Moreover, it helped improve on lifting, social life and reduce in the duration and the frequency of outbreak of pain. Finally, according to the result of this study, the combined exercise program was shown to be effective and appropriate for the patients suffering from work-related back problems.

Functional and esthetic recovery through reconstruction of the oral and maxillofacial system is important for patients who underwent mandibulectomy due to lesions such as oral cancer. The fibula free flap, which is frequently used in the reconstruction of the mandible, is easy to prosthetic restoration with implant placement. However, patients with growing periods have difficulty in treatment with implants when the size of the fibula is small and residual growth remains. This case is an 11-year-old female patient who underwent mandibulectomy due to osteosarcoma and reconstruction of the mandible using a fibular free flap. Functional and esthetic recovery were obtained through prosthetic restoration using implant-supported fixed prostheses. Implantation site, number of implants, and type of prostheses were considered. Implant-supported fixed prostheses were delivered at 13 years old, and after an additional 1 year observation, stable results were obtained. However, observing changes in the maxillofacial system through further examinations is necessary.

Complete denture prosthodontics includes replacement of natural teeth and associated maxillary and mandibular structures for full edentulous patients. The final objectives of prosthodontic treatment include esthetic and functional rehabilitation. Because the esthetic demand of senior patients has increased esthetic requirement should not be overlooked in denture treatment. In complete denture treatment, attempts have been made to reproduce tooth wear, arrangement, recession of cervical gingiva, staining, improved gingival shade and so on. This 61 year old female patient came to the Department of Prosthodontics with the chief complaint that dentures made 5 years ago in a local clinic were broken and did not fit well. The patient put more emphasis on fabrication of natural and esthetic dentures than recovery of masticatory function. Remake of maxillary complete denture and mandibular implant retained overdenture was planned. In order to create esthetic and natural contour, Aesthetic Color Set Easy system$^{(R)}$ (Candulor dental GmbH, Wangen, Germany) was used to make complete dentures reproducing various gingival shades. Patient's esthetic satisfaction was high. When complete denture prosthodontics treatment involves appropriate expression of individual characteristics in addition to proper selection of esthetic materials, treatment will give satisfaction to both dentist and patient.

전방 불안정성의 수술적 치료의 목적은 안정성을 회복하고 동통 없는 기능 회복에 있으나 이러한 목적과는 달리 여러 합병증이 발생하여 결과가 불량하게 되는 경우가 종종 발생한다. 따라서 치료의 실패를 줄이기 위해 최대한 노력하여야 하며, 일단 실패가 발생하게 되면 정확한 원인과 해부학적 병적 상태를 정확히 파악하여야 보다 좋은 치료 결과를 얻을 수 있다.

Orthodontic treatment is obviously the first choice to get aligned teeth cause of conservative treatment. But it is impossible to get highly esthetic result only orthodontic treatment in case of peg lateralis, discrepancy tooth size, discolored teeth or fractured teeth. As all treatment does, especially in esthetic treatment it is always required interdisciplinary diagnosis and treatment plan; orthodontics, periodontology, prothetics, implant therapy. As also, the treatment should be maintained long-term treatment with stable and harmonious state by esthetic satisfaction and functional occlusion those who needs various dental care as interdisciplinary treatment. This case is the laminate treatment with the orthodontic treatment on 37 ages/ Female patient who has cross bite at anteriors and premolar area and abrasion on centralis at right maxilla. By orthodontic treatment aligned teeth positions, it makes functional occlusion. As laminate treatment with minimum teeth preparation is able to release anterior esthetics. Follow up check for 2 years has been performed since the final prosthetics delivery to the patient. No sign of relapse, fracture of laminate were detected.

The hemodynamic effects of thyroid hormones which is well established, affect myocardial contractility, heart rate, and myocardial oxygen consumption. The alterations in thyroid function test are frequently seen in patients with nonthyroidal illness and often correlate with the severity of the illness and the prosnosis. In this study, thyroid hormone changes were investigated in 20 patients who received cardiopulmonary bypass(CPB). All patients showed a state of biochemical euthyroidism preoperatively: The results were as follows : 1. Serum triiodothyronine(73) reached to its nadir(30.05 $\pm$ 17.5ng/dl, p(0.001) at 10 minutes after the start of CPB and remained low(p(0.05) throughout the study period. 2. Serum thyroxine(74) concentr tion slightly decreased after CPB, but maintained within normal range. 3. Serum free thyroxine(W4) concentration slightly increased after CPB, but maintained within normal range. 4. Serum thyroid stimulating hormone(TSH) concentration increased 10 minute after CPB, reached to its nadir(3.37 $\pm$ 0.81u1U/m1, p(0.001) at 2 hours after CPB. After then, serum TSH concentration decreased and reached its normal levels at 24 hours after CPB. 5. The patients whose postoperative recovery was uneventful(Group 1) had higher serum 73 levels than those who had postoperative complications(Group 2)(p<0.05). Group 1 showed elevating patterns of serum 73 in the fourth day after operation, whereas group 2 did not show such an elevating pattern. These findings are similar to the euthyroid sick syndrome seen in severely ill patients and indicate that patients undergoing open heart surgery have suppression of the pituitary-thyroid axis.

최근 자연환경보전이라는 새로운 패러다임의 대두로 하천환경의 보전과 개선의 필요성에 대한 공감대가 형성되기 시작하였으며, 하천의 환경적 기능을 고려하는 관리방안이 제시되고 있다. 이를 반영하는 것이 최근 활발히 논의되고 있는 하천기능 복원기술의 개발이다. 이는 하천정비나 관리에 있어서 하천의 생태적 기능에 초점을 맞추는 것으로 1990년대 이후 확산된 환경기능을 고려한 하천정비 및 관리보다 구체화된 하천의 생태환경기능의 회복을 포함하고 있다. 본 연구에서는 내구성이 강화된 식생매트를 개발함에 있어 라텍스를 이용한 친환경 코팅 매트를 개발하여 식물의 정착효과를 비교분석하여 효율적인 저수호안공법을 제시 하였다.

본 논문은 필드버스 인터페이스를 위한 이중구조의 결함내성형 마이크로콘트롤러 구조를 제시하고, 테스트 환경을 구축하여 고장허용 기능을 검증한다. 이중구조의 결함내성형 마이트로 콘트롤러는 두 개의 프로세서 모듈의 출력을 비교하여 고장을 발견하고, 고장을 발견한 경우 버스 출력을 차단함으로써 전체 시스템의 오동작을 방지한다. 일단 고장을 발견하면 자체 진단을 통해 고장 상태를 판다하여, 영구적인 고장일 경우 정지하고 일시적인 고장일 경우에는 재시작을 통해 정상동작으로 복귀함으로써, 고장정지 및 일시적인 고장으로부터의 회복기능을 제공한다. 이중구조의 결함내성형 마이크로 콘트롤러에 필드버스 인터페이스 기능을 추가하여 자체적인 응용 노드로서의 기능을 수행할 수 있도록 한다. 그리고 이러한 노드를 MC68360프로세서를 이용하여 구현하고, 인위적인 고장주입을 통하여 그 기능을 검증한다.

The purpose of this article is to present the environmental enrichment(EE) method used to improve the functional recovery and change of brain plastic in animal experimental models of stroke. In animal experimental models of stroke, the environmental enrichment is effective in altering the morphological, biochemical and behavioral characteristics of the brain and thereby improving the functional outcomes. In this review article, we address the effects of EE in achieving a functional recovery in animal experimental models of stroke, thus attempting to describe them in patients with stroke from both occupational and rehabilitation perspectives.

대개 근위부 족저근막염에 의해 야기되는 족저부 뒤꿈치 통증은 흔한 족부 질환이다. 족저근막염을 가진 대부분의 환자에서 비수술적인 치료는 효과적이지만, 통증 해결은 1년까지 요구된다. 수술이 요구된다면, 근막의 절반 이상을 유리하는 것은 기능적인 결손을 피하기 위해 배제되어야 한다. 외측 족저신경의 감압은 무지외전근의 기시부 주위에 통증이 있는 환자에서 추가된고 족저 근막 유리술의 정해진 일부분이 된다. 가끔, 족저부 뒤꿈치 골극 절제술이 필요하지만 이것은 시술의 이환율을 더하고 회복 시간을 지연시킨다.
