Materials and Methods: We studied 50 cases of peroneal perforating branch about branching pattern, course, length of vascular pedicle, and perforating level of the perforating cutaneous branches from Oct. 1985 to November 2003 by doppler flow meter and intraoperative findings. Results: 1) The perforating cutaneous branches were classified into four types, the Straight Branch (27cases), the Proximal Oblique Branch (11cases), the Branch from Muscular Artery (10cases), the Distal Oblique Branch(2 cases) respectively. The most common patten was Straight Branch, that was 54%. 2) There were 3 pathways of these branches, the most common one passed between the Soleus and Peroneus muscles(34 cases, 68%) 3) The length of vascular pedicle in Buoy Flap was variable from from 3 cm to 15 cm, but 32 cases(64%) were distributed between 5 cm and 6 cm. 4) The perforating level of branches were 5.9 cm in average from fibular neck to subcutaneous perforator artery 5) Peroneal Buoy Flap in possible to reconstruct both seperated bone and skin defect in some distance by One-Stage Operation and we can harvest maximal $8{\times}16cm$ sized flap in one perforating artery. If we include more two perforating artery, we get more wide flap which can cover large defect.

This paper presents the experimental and theoretical results of the dynamic responses of a pendular energy extractor in a two-dimensional wave channel. By adopting a wave maker with varying wave height and period, the dynamic responses of the pendular buoy were experimentally obtained. Furthermore, with the aid of the co-simulation of moving particle analysis and rigid dynamic analysis, the dynamic responses of the pendular system were evaluated. In order to validate the feasibility of the proposed wave power generator, the force tuning of the pendular system with restoring energy was carried out. The results provide proof of concept data for the development and design of a commercial model for horizontal wave power generators in the shoreline area.
