관절경적 일열 봉합법은 잘 정립된 회전근 개 봉합술로 우수한 임상성적을 보여왔다. 하지만, 수술 후 재파열의 빈도가 높은 것으로 알려져 있어 다양한 방법들이 술 후 재파열을 줄이기 위하여 시도되어왔다. 일부 연구들에서는 해부학적 회전근 개 부착부를 재건하면 봉합한 회전근 개의 치유 및 초기 역학적 강도를 증가시킬 수 있을 것이라고 보고하였고, 이열 봉합법이 해부학적 회전근 개 부착부 재건과 봉합부의 강도를 증가 시키고, 간격형성을 감소 시킬 목적으로 소개되었다. 하지만, 재부착된 회전근 개 건의 장력, 봉합된 건의 혈관 형성 등의 생물학적 치유환경이 일렬 봉합법에 비하여 우수함이 아직 입증되지 않았고 수술 후 기능적 개선도 측면에서도 두 봉합술간 차이가 없으므로, 수술 수기가 상대적으로 쉽고, 요구되는 기구 및 내고정물의 추가적 비용이 적어 경제적인 측면에 장점이 있는 일렬 봉합법은 여전히 추천되는 수술수기이다.

The single cell gel electrophoressis(SCGE) assay, also known as the comet assay, is a rapid, simple, visual and sensitive technique for measuring and analysing DNA breakage in mammalian cells. The SCGE or comet assay is a promising test for the detection of DNA damage and repair in individnal cells. It has widespread potential applications in DNA damage and repair studies, genotoxicity testing and biomonitoring. In this microgel electrophoresis technique, cells are embedded in agarose gel on microscope slides, iysed and electrophoresed under alkaline conditions. Cells with increased DNA damage display increased migration of DNA from the nucleus towards the anode. The length of DNA migration indicates the amount of DNA breakage in the cell. The comet assay is also capable of identifying apoptotic cells which contain highly fragmented DNA. Here we review the development of the SCGE assay, existing protocols for the detection and analysis of comets, the relevant underlying principles determining the behaviour of DNA and the potential applications of the technique.

Recently, the self-healing technique is being investigated to repair the damaged polymeric composites by the use of microcapsules with the healing agent. This technique can obtains both the damage detection and the damage repair simultaneously over the converntional repairing techniques. In this study, the effects of the catalyst ratio to the healing agent and thermal characteristics to the mixtures of healing agent are investigated through single lap shear tests and DSC. The Healing agents such as DCPD, ENB, and their mixtures are considered and Grubb's catalyst is used as a catalst.

For a bursal-side retracted laminated rotator cuff tear, simple repair of the retracted bursal-side rotator cuff might be insufficient because the repaired tendon could remain as an intratendinous tear of the rotator cuff. We present a repair method for intratendinous rotator cuff tears using the suture-bridge technique. We believe that this method helps to preserve the remnant rotator cuff tendon without tissue damage and restores the normal rotator cuff footprint in bursal-side delaminated rotator cuff tears.

The repair of esophageal atresia with a long gap continues to pose difficulties for the surgeon. There is a general agreement that the child's own esophagus is the best, however, primary repair is not always possible. Foker JE et al. (1997) developed a technique of esophageal lengthening using external traction sutures. We successfully treated one patient with a 4.5cm gap esophageal atresia (4 vertebral spaces) using the external traction suture technique.

Various minimally invasive repair techniques have been performed for acute Achilles tendon rupture. Despite this, it is difficult to use these techniques in common practice because of the necessity of special instruments. We propose a novel minimal invasive technique using sponge holding forceps, which are commonly used in the operating room for the acute Achilles tendon rupture.

대부분의 환자는 관절경적 회전근 개 봉합술 후 통증이 완화되고 기능적 호전을 보이지만 일부 환자는 수술 후에도 증상이 지속된다. 재파열은 생물학적, 기술적, 외상적 요인이 복합적으로 작용하여 발생한다. 회전근 개 봉합술 후 재파열이 지속되는 통증의 원인일 수도 원인이 아닐 수도 있다. 따라서 이런 환자들의 평가 및 치료는 난해하여 철저한 문진, 이학적 검사, 적절한 영상 검사를 통해서 통증의 원인에 대한 분석이 이루어져야 한다. 재봉합술의 시행 여부는 환자의 나이, 기능적 요구도 회전근 개의 상태, 수술 전 관절 운동 범위, 삼각근의 상태, 관절과 상완 관절의 관절염의 유무에 따라 결정되어야 한다. 성공적인 재봉합술은 술기뿐만 아니라 수술 전 환자 교육 또한 중요하다.

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 should not be repaired beyond the limits of the features and techniques which had been adopted in those days of establishment. On the premise, this paper is to examine the materials and technique of wall plaster work in the government building constructions in the Joseon dynasty. The result of this examination shall 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 materials and technique which applied to wall plaster work in those days were quite different from the present. The technique that was used to wall plaster of government buildings in those days was not a lime wall plaster, but sand coat one. The kinds of material for setting of the sand coat wall plaster had been revised with the change of the times or constructions. The main kinds of material were composed of sand, white clay, paper fiber, and cereal starch. However, the present materials were composed of sand, white clay. Therefore, the present materials and technique which applied to wall plaster work for the repair and restoration of architectural cultural properties have to be revised and corrected.

Purpose: A Tessier classification number 7 cleft is an uncommon malformation that results from a failure of mesenchymal fusion within the maxillary and mandibular prominences of the 1st pharyngeal arch. Many operative techniques of the number 7 cleft repair have been proposed to restore function and improve aesthetics. Fifteen patients underwent repair of a number 7 cleft over 13 years by a modification of the surgical Technique, and an appraisal of the operative outcome is reported herein. Methods: A retrospective review was conducted involving 15 patients with number 7 clefts who underwent surgery from 1996 to 2009. The changes in surgical technique included skin closure, attachment of the orbicularis oris muscle, and position of the repaired commissure; the changes were analysed with a review of the medical records and the outcomes of surgery were analysed via photographs. Specifically, the technique of skin closure was changed from the a Z-plasty to a linear closure, the orbicularis oris muscle overlapped attachment was replaced by a side-to-side approximation with horizontal mattress sutures, and the position of the repaired commissure was changed from 1 mm laterally to 1 mm medially in reference to the non-cleft side. Results: A Z-plasty caused additional cutaneous scarring, an overlapped attachment of the orbicularis oris muscle caused a thick oral commissure, and the repaired commissure migrated to the lateral side, so a 1 mm, laterally-positioned commissure caused asymmetry. The altered procedure included a linear skin closure, a side-to-side orbicularis oris muscle approximation, and a 1 mm, medially-positioned commissure, which together resulted in a good outcome. Conclusion: The altered procedure for repair of a number 7 cleft as described herein, yields a short scar, no functional problems with the orbicularis oris muscle, a thin oral commissure, and symmetry of the repaired commissure.

The reliability of cold-bonding repair technique of carbon-fiber reinforced plastics (CFRP) laminates, often used as a temporary repair for the airplane maintenance, has been evaluated during cyclic loading and localized heating by nondestructive methods. Major concern was given to the evolution of damage after repair in the form of delaminations due to localized heating and cyclic loading combined. An area of interest both on the specimen repaired by cold-bonding and the specimen without repair where delaminations were induced by localized heating and cyclic loading was monitored by acoustic emission (AE) testing and further examined by pitch-catch low-frequency bond testing, and pulse-echo high-frequency ultrasonic testing. The results showed that the reliability of cold-bonding repair would be significantly reduced by the localized heating and cyclic loading combined rather than by the cyclic loading only. AE monitoring appeared to be an effective and reliable tool to monitor the integrity of temporarily repaired CFRP laminates in terms of the structural health monitoring (SHM) philosophy.
