  • In this study mechanical and environment ability of FRP pole for a distribution line about high strength and good insulation properties. The basic filament winding process creates a helical winding pattern. In mechanical analysis of splice with mechanical fastened joint it is important to evaluate a critical load of faster having maximum stress. It is also present a result of several examples to compare this with analytical one. On repair design this finite element method will be used as basis. The influence of environmental factors, such as elevated temperatures, high humidity, and corrosive fluids, and ultraviolet(UV) rays, upon the performance of polymeric matrix composite is of concern in many applications.

  • 소절개 봉합술은 관혈적 봉합술에 비해 동반된 관절와 상완 관절(glenohumeral joint) 내의 병변을 확인하고 이에 대한 처치를 시행할 수 있으며, 견봉하 감압술과 함께 동반된 견봉 쇄골 관절의 병변을 치료할 수 있다. 또한 삼각근 기시부에 대한 손상을 최소화하기 때문에 빠른 재활과 조기 퇴원을 시행할 수 있는 등의 장점이 있다 관절경적 봉합술에 비해서는 수술 술기가 어렵지 않기 때문에 항상 좋은 결과를 기대할 수 있다 회전근 개 파열에 대한 수술을 시행할 때 관절경적 봉합술이 모든 경우에서 관혈적 또는 소절개 봉합술에 비해 좋은 결과를 나타내는 것은 아니다. 환자가 심한 골다공증이 있는 경우, 기술적 문제가 있는 경우, 봉합 후 회전근 개에 지나친 긴장이 염려될 때는 항상 소절개 봉합술로의 전환을 시도하여야 한다. 소절개 봉합술을 시행한 경우에도 관절경적 봉합술시와 비슷한 좋은 결과를 얻을 수 있고, 치료의 결과는 수술의 방법보다는 정확한 술기 및 수술 전 환자의 상태에 좌우된다고 하겠다.

  • The open Broström procedure is considered the surgery of choice for treating chronic lateral ankle instability. The role of arthroscopy has gained popularity in the surgical treatment of chronic lateral ankle instability, partly for the ability to manage the intra-articular pathology combined with ankle instability. Arthroscopic techniques can be divided broadly into the arthroscopic-assisted Broström technique and arthroscopic all-inside ligament repair. The clinical results of these arthroscopic techniques are similar to open procedures. The arthroscopic technique may be an excellent alternative to the open Broström procedure in treating chronic lateral ankle instability when applying the appropriate indications.

  • Background: We investigated the resolution of pain and functional recovery of shoulder after arthroscopic removal of calcific deposits in patients with chronic calcific tendinitis. Methods: We enrolled 39 patients who were treated arthroscopically for chronic calcific tendinitis that had been non-responsive to at least 6 months of conservative treatment. We evaluated clinical outcome in terms of the American Shoulder Elbow Surgeons (ASES), the Constant score, the visual analogue score (VAS) for pain. We used plain radiography to measure the size of the calcific deposits. We also analyzed the clinical outcomes in terms of whether or not a cuff repair was performed or the degree of removal of calcific deposits. Results: We found that complete resolution of pain took on average 5.7 months after the arthroscopic treatment. The ASES and the Constant score significantly improved from the 3-month follow-up, however it took 6 months until the scores reached on average 80 points or above. We found that these clinical outcomes at the final follow-up did not significantly differ by whether or not cuff repair was performed. Similarly, we found that the clinical outcomes did not significantly differ by the degree of calcium removal. Conclusions: We found that arthroscopic removal of calcification leads to improved clinical outcomes in patients with chronic calcific tendinitis. However, our findings show it takes at least 6 months for the clinical improvement to become statistically significant. We also found that concomitant cuff repairs or the degree of removal of calcification does not affect the clinical outcome of the arthroscopic treatment.

  • Since the 1970's, UNESCO and ICOMOS have adopted or emphasized on the principles of historic preservation. One of them is what to require a repair have not to be repaired beyond the limits of the features and techniques to have been born in those days of establishment. On the premise, this paper is to examine the materials and technique of lime plaster work in order for roof ridge, and for bond paste of stones and bricks in government constructions in the late of Joseon dynasty(17~19c). The result of this examination will come up with a basic conformity in the case of repairing the building established in the late of Joseon dynasty. This paper is carried out for the proper repair and restoration of architectural cultural properties. Construction reports and other documents in those days are examined for the study. Following conclusions have been reached through the study. The components of old plaster mixtures which agglutinate stones each other were quicklime, perilla oil, and paper fiber. The components of old plaster mixtures which point joint of black bricks consisted of slaked lime, perilla oil, paper fiber, and cereal starch. These components were the same as coat surface of roof ridges. In the case of times, one of the following sand, white clay, sap of boiled elm bark was added to these components for the purpose of high efficiency. These materials and techniques which applied to plaster work of those buildings had developed in the process of making royal tombs. But these materials and techniques were quite different from the present.

  • Purpose: To evaluate the clinical results of anteroinferior tibiofibular ligament avulsion fracture accompanied ankle fractures treated with anatomical reduction and internal fixation. Materials and Methods: From January 2007 to April 2010, 30 cases with anteroinferior tibiofibular ligament avulsion fracture that treated with anatomical reduction and internal fixation were analyzed. The average follow-up period was 26 months (minimum 6 months). We have reviewed the bony union, complication and subjective satisfaction according to the fracture classification and method of internal fixation. Results: Among 30 cases, 28 cases were occurred in Lauge-Hansen classification supination-external rotation type, one case was fracture-dislocation and one case was Maisonneuve fracture. We have performed internal fixation with Mini screw in 11 cases, K-wire in 10 cases, repair in six cases and Mini screw & K-wire in three cases. In all cases bony union was completed. two cases in Mini screw, one case in K-wire, two cases in repair and one case in Mini screw & K-wire revealed LOM of ankle joint. Skin irritation and superficial peroneal nerve irritation happened in one case each. Other cases show good subjective satisfaction. Conclusion: Anteroinferior tibiofibular ligament avulsion fracture accompanied with ankle fracture is a good clinical outcome with internal fixation. So we should not miss out the anteroinferior tibiofibular ligament avulsion fracture in radiologic evaluation or operation room.
