With the recent development in microsurgery, the use of a perforator flap has been widely implemented. If the length of the ALT flap pedicle is insufficient despite adequate preoperative planning, pedicle length extension is necessary. We planned for a reverse ALT free flap using the distal vessel of the descending branch for pedicle length extension in the case of ALT perforator branch originating from the proximal portion of the descending branch. For the management of venous congestion, the distal venae comitantes were anastomosed to the proximal venous stump in an antegrade manner, successfully resolving the venous congestion. Modified reverse-flow ALT free flap, wherein the venae comitantes are anastomosed to the proximal vein stump, is a good option that allows for relatively simple pedicle extension within the same operative field when securing an adequate pedicle length is difficult because of the origin of the perforator from the proximal descending branch, unlike the initial surgical plan.

산느타리버섯의 원목재배 시험결과 플라스틱 콘테이너 상자($50cm{\times}35cm{\times}30cm$)내에 토양매립하였을 경우 '향산' 품종에서는 원목당 수량이 340 g 정도로 톱밥종균 접종과 액체종균 접종에서 큰 차이가 없었고, '호산' 품종에서는 톱밥종균 접종이 원목당 450 g으로 수량이 높았으나 액체종균 접종은 259 g으로 낮게 나타났다. 원목을 비가림하우스내 토양에 매립하였을 경우 미루나무에 비해 가중나무의 수량이 높게 나타났고, 품종에 있어서는 '향산' 품종보다 '호산' 품종의 수량이 더 높게 나타났다. 산느타리버섯의 적정 수종 선발시험에서는 버드나무와 벚나무가 '호산' 품종 및 '향산' 품종 모두에서 수량이 높게 나타났다.

Objective : Flat back syndrome constitutes a syndrome complex characterized by the loss of normal lumbar lordosis. Various techniques of correction for flat back syndrome have been reported. Posterior extension osteotomy has certain drawbacks. Forceful hyperextension of the spine may result in vascular complications such as rupture of the aorta or the inferior vena cava and stretching of superior mesenteric artery, and pseudoarthrosis. We describe a rationale and technique of transvertebral posterior extension osteotomy to avoid complications of posterior extension osteotomy and to achieve an correction of 30 degrees of flat back syndrome. Method : A 63-year-old woman with degenerative lumbar kyphosis presented with low back pain, thigh pain, knee pain and walking difficulty. Transpedicular fixation from L1 vertebra to S1 vertebra was accomplished for lumbar degenerative kyphosis. After 6 months, the patient presented with flat back syndrome. A second operation was performed with transvertebral posterior extension osteotomy. Result : With short segemental fusion, early bone fusion and correction of 30 degrees were achieved. Conclusion : Transvertebral posterior extension osteotomy provide an 30-60 degrees of correction of flat back syndrome. This technique is considered to be good method for the revision of lumbar degenerative kyphosis.

In order to evaluate the grouting effects of water-rich fault in tunnels systematically, a feasible and scientific method is introduced based on the extension theory. First, eight main influencing factors are chosen as evaluation indexes by analyzing the changes of permeability, mechanical properties and deformation of surrounding rocks. The model of evaluating grouting effects based on the extension theory is established following this. According to four quality grades of grouting effects, normalization of evaluation indexes is carried out, aiming to meet the requirement of extension theory on data format. The index weight is allocated by adopting the entropy method. Finally, the model is applied to the grouting effects evaluation in water-rich fault F4-4 of Qingdao Jiaozhou Bay Subsea Tunnel, China. The evaluation results are in good agreement with the test results on the site, which shows that the evaluation model is feasible in this field, providing a powerful tool for systematically evaluating the grouting effects of water-rich fault in tunnels.

The Korean supreme court said that Mrs Kim who was in a persistent vegetative state had a right to die if she had a presumed will or assumption of dying against Severance hospital in 2009. Presumed would be vague and can not be subjective to conjecture though, the court had a developed trial on the case. I recommend the higher valued notion such as the 'right to decide on the life extension' is more logical than assumptive will. To achieve this recommendation, I will search right to life, right to decision, human dignity and find the good relationship between them. In conclusion, I will announce that if PVS patients without advanced directives aren't able to express their will and no one could not assume their right to die in spite of meaningless life extension. So only the due and strict procedure about the extinction of meaningless PVS patients will allow them to sacrifice themselves or remove life extension ventilators. Also active euthanasia would be possible under the strict procedure of making advanced directives and the act of helping active euthanasia additionally, the crime of abetting suicide would not be executed in the legal scope.

Background: The traditional nasolabial V-Y advancement flap is widely used for midface reconstruction, particularly for the lower third of the nose and upper lip, as its color and texture are similar to these areas. However, it provides insufficient tissue to cover large defects and cannot restore the nasal convexity, nasal ala, and adjacent tissues. The purpose of this study is to investigate the modified nasolabial V-Y advancement flap with extension limbs the along alar crease for the reconstruction of complex midface defects. Methods: A retrospective analysis of 18 patients, who underwent reconstruction with the modified nasolabial V-Y advancement flap, was performed between September 2014 and December 2022. An extension limb was added along the alar crease, adjacent to the defect area, and was hinged down as a transposition flap at the end of the advancement flap. Results: The extension limb along the alar crease successfully covered large and complicated defects, including those of the ala, the alar rim, the alar base, the nostrils, and the upper lip, with minor complications. Conclusion: The alar crease is a good donor site for the reconstruction of large and complex nasal and upper lip defects.

The application of knowledge management concepts as a way to improve project success is an emerging topic for project management researches around the world. The Construction Extension to the PMBOK^® Guide Third Edition documents the knowledge and practices that are generally recognized as good practices for managing engineering and construction projects. However, it is not unusual to see that engineering and construction projects suffer from poor performance. Based on a critical literature review, a theoretical framework is developed for the application of knowledge management in engineering and construction projects. This framework is subsequently applied as a lens to examine the construction extension to the PMBOK^® Guide, aiming to identify the key characteristics of knowledge management in this standard. This research also aims to highlight those aspects of the construction extension to the PMBOK^® Guide that can be improved from the knowledge management perspective. Recommendations are made to improve this standard by means of applying knowledge management concept so that better project outcomes can be achieved.
