[丘比特][丘比特][丘比特]有关Presentation 的小技巧（上）
[姜饼人]做presentation一定要有一份优秀的PPT，开头中间结尾一定要有衔接！
[给你小心心]1.开头：一定是aims and objectives类似的slide，千万要说清楚是什么motivite我，我的motivition是什么再进入问题，包括问题的背景，为什么重要
[给你小心心]2.提到前辈们的literature review，介绍背景知识或者技术性的bastic information
[给你小心心]3.表达创新点：你究竟怎么去做的（坚决不可以省略！）

#Facial Plastic Surgery# #整形# #整形外科# #整形[超话]# Restoration of the inner nasal lining is an essential factor in successful nasal reconstruction. Among various methods, free full-thickness skin grafting represents a readily available and feasible technique. A prerequisite for success is a secure and immobile fixation to the undersurface of the nourishing forehead flap. This retrospective study aims to evaluate the results of multiple quilting sutures to secure free full-thickness skin grafts for the reconstruction of the inner nasal lining in partial and extended nasal reconstruction. Between February 1, 2015, and December 31 2018, 16 patients underwent three-stage nasal reconstruction of all three layers using a forehead flap. All full-thickness free flaps were harvested from either the neck or inguinal area and fixated to the undersurface of the distal part of the forehead flap by multiple quilting sutures. All but one free skin grafts healed well (seven ♀; mean: 63 years; range: 52–81). Four patients developed minor complications that resolved completely through conservative treatment. One patient with a history of stroke, extensive nicotine abuse, and arterial hypertension developed flap necrosis that required two surgical revisions and ended up with a stenosis of the left nostril. The follow-up time averaged 18.4 months (range: 3–55 months). Multiple quilting sutures are an effective and feasible option to fixate full-thickness free skin grafts on the undersurface of the forehead flap for the reconstruction of the inner nasal lining. They are not associated with increased risks for necrosis and can be applied even to extended full-thickness nasal defects in selected cases.

- Lesson aims:
1. Understand that air, water and solids can spread.
  了解空气、水和固体可以传播声音。
2. Learn briefly how the ear works and experience the illusion of sound.
  简单了解耳朵的工作原理并体验声音错觉。
 
- STEM activities:
1. What brings sound to your ears? 设计实验并验证声音是如何进入我们的耳朵的。
2. Listen to the sound they make. 听听通过不同介质，物体发出的声音有没有变化。
3. Illusion of the ear. 声音错觉。
4. How do we hear? 耳朵是如何听声音的。
 
今天我们进入了新的单元，音乐之声。通过将手放在喉咙处发声，敲击鼓面等引入活动，我们初步了解了振动产生了声音。生活中的声音图标通常会用波浪线表示，其实声音就是一种波，我们是可以利用示波器看到声音的波形的。接下来我们进入了本节课的重点环节，讨论声音是通过什么传到我们的耳朵里的，并设计实验验证。最开始孩子们给出了很多猜想：什么都不需要、空气、门窗、桌子等等，我们进行初步归纳总结：空气、水、固体、真空，然后孩子们通过讨论细节自己设计了一系列的实验来验证，其中真空环境我们使用到了真空泵，实验设计的流程孩子们可以自己尝试介绍出来。这是孩子们完成简单实验设计的尝试，今天总体来说，孩子们想法还是比较发散的，但设计环节的逻辑严谨性不够，后续我们还会有更多类似的设计需要孩子们进行尝试的。接下来的课程里，我们使用铁勺和毛线，敲击不同的物体，比较了通过空气和通过铁勺毛线这样的固体听到的声音的差别，同样的道理，我们听到的自己的声音和别人听到的我们的声音也是不同的~最后，我们制作了一个小小的模型，感受了声音的错觉。拓展活动里，简单了解了耳朵听到声音的过程。接下来的几节课里，我们会依次了解声音的其他特性的，大家有兴趣的可以先自行了解一下。
