Abbe瓣术式发展、手术效果评估方法及影响因素

Abbe瓣是以下唇动脉为蒂的交叉唇瓣,它将含有下唇皮肤、肌肉及黏膜组织的全厚瓣向上旋转,用以修复上唇正中的组织缺损或瘢痕挛缩。自1898年Abbe提出这一术式并将其用于临床之后,对手术方法的改良与创新层出不穷,均旨在解决蒂部体积过大、唇部动度不佳、供区瘢痕形成等问题。手术效果的评价方法有问卷调查、等级评分系统等定性评价方法,以及以唇指数为代表的定量评价方法。影响手术效果的因素包括组织缺损的类型、下唇动脉的走行及位置、组织瓣和蒂部的大小形态等。本文就Abbe瓣的术式发展、手术效果评估方法以及手术效果的影响因素作一综述。

Low-carbon Agriculture Development Models in Southern Jiangsu Province

[Objective] To investigate the appropriate low-carbon agriculture model in Southern Jiangsu Province. [Method] Through the analysis of regional features in Southern Jiangsu and several matured low-carbon agriculture development models at present, the low-carbon agriculture development modes suitable for Southern Jiangsu were investigated, and corresponding supporting measures for the development of the models were put forward. [Result] Low-carbon agriculture is the environment- friendly agriculture which achieves low emissions, low pollution, high efficiency and high-yield through efficient recycling of energy and resources and continuous im- provements on ecological environment. With a variety of development models, the specific development model for practical use should be determined according to the local conditions, and supported by corresponding supporting measures, to achieve the rapid development of low-carbon agriculture. [Conclusion] This study laid the foundation for the development of low-carbon agriculture model in Southern Jiangsu.

Development of 8-inch Key Processes for Insulated-Gate Bipolar Transistor

Based on the construction of the 8-inch fabricat ion line, advanced process technology of 8-inch wafer, as well as the fourth-generation high-voltage double-diffused metal-oxide semiconductor(DMOS+) insulated-gate bipolar transistor(IGBT) technology and the fifth-generation trench gate IGBT technology, have been developed, realizing a great-leap forward technological development for the manufacturing of high-voltage IGBT from 6-inch to 8-inch. The 1600 A/1.7 kV and 1500 A/3.3 kV IGBT modules have been successfully fabricated, qualified, and applied in rail transportation traction system.

Discussion on Art Design Education in Colleges and Universities in Digital

At present, the reform of colleges and universities in our country is in full swing. In the course of teaching design of art in colleges and universities, it is necessary to change the teaching mode in time to adapt to the new teaching development environment. In the era of digital development, we need to give full attention to the optimization of art design teaching in colleges and universities, and run new teaching techniques. This paper mainly analyzes the advantages and importance of the digital art design in colleges and universities, and then discusses the application of digital technology in the art design teaching and the concrete teaching optimiTatiun strategy in detail. Hoping to through this theoretical research, contribute to the improvement of the quality of art design teaching.

Discussion on the Classroom Teaching Management of the Art and Design Major in Higher Vocational Colleges

As a teaching aid, the classroom management model of art and design major courses undoubtedly should follow the rules of art education. Compared with colleges and universities, the teachers in higher vocational colleges often need to educate many students of poor foundation and bad habits, so the management model should be explored more deeply and specifically. Through the depth analysis of the teaching environment, objects, and objectives, a relatively solid, perfect management system including discipline management and system control, mental management and standard attitudes, process management, incentive and interaction, evaluation management, and ability goal is proposed, for the purpose of providing a powerful guarantee for the classroom teaching effect of the an and design major in higher vocational colleges by using reasonable classroom management methods and means. As a result, a solid foundation is laid for the an and design students to become the professionals of the sustainable development.

Development and Commercialization of New Autonomous Low Power Systems for Energy Harvesting

This paper evaluates new technologies for energy harvesting from the environment. We assess the reliability, accuracy, and autonomy of low power electronic devices, their market opportunities, and their ability to enhance sustainable development. For small, portable applications that need long lifetime energy supply systems, size, width, finite energy lifetime, and the need for replacement are important drawbacks. New supply alternatives should be explored that are able to make recharging easier or to remove battery dependence altogether. A new trend in the energy sources for low power applications has emerged in recent years, involving the harvesting of the energy available in the environment to supply power for electronic applications instead of using battery technologies that provide only short, finite amounts of energy. In this paper, we describe an all-purpose module of energy harvesting from mechanical, thermal, solar and RF energy sources developed at the University of Barcelona. We provide proof of concept in order to incorporate this novel energy technology in a wide range of applications and environments.
