運用Arduino控制Scratch—為身心障礙兒童打造手眼協調和專注力訓練的體感遊戲
本研究針對身心障礙兒童設計具有趣味性、能練習不同動作的體感遊戲進行訓練。並致力確保這方案的順暢和可行性,改正軟硬體缺失,簡化製作流程,讓有需求的人能輕鬆複製、修改,發展更多有創意的輔具,幫助身心障礙兒童。 體感遊戲以Arduino搭配感測器,發送鍵盤指令控制Scratch。其中「切水果遊戲」利用超音波偵測手勢模擬切水果,訓練手部粗大動作;「瘋狂俯衝遊戲」運用傾斜陀螺儀和轉動光柵控制飛機方向和速度,搭配ESP32藍芽無線控制,訓練手腕、手指精細動作。 進行「轉移積木測試」評估,手眼協調和專注力較前測進步7%~56%。對兒童,這不是枯燥輔具練習,而是遊戲挑戰,受測者更有信心且樂於訓練,全程充滿歡笑。

Investigating the application of nanotechnology for detecting fishes hatching time
Introduction: Using advanced technologies such as nanotechnology in the food and fishery industry, as one of the most important industrial sectors of countries, has received too much attention. Traditionally, fishing and hunting have been considered important sources of supplying food. The subject and methodology: The study aims to investigate nanotechnology for detecting fish hatching time. This is a review article that collects the information from databases such as Sid, civilica, and Google Scholar. In the end, 22 papers were studied for extracting and collecting the required information from the abovementioned scientific database. Finding: After examining the food, drug, and agricultural-related papers published from 2009 to 2020, it was concluded that small Nano-sensors, controlling & monitoring systems made from nanotechnology can be installed on fishing nets, fishing rods, and other fishing equipment. These devices (Nano-sensors and controlling & monitoring systems) will help fishes so that they don’t get caught. In this way, as a fish gets close to the fishing equipment, it will receive sound, smell, or heat-based alarm. Therefore, the fish will stay away from the fishing equipment. The result: according to the finding of this study, it can be concluded that excessive fishing in the hatching time will be avoided by the application of nanotechnology in the fishing equipment. As a result, the following advantages will be secured: 1- There are lots of opportunists who misuse fish during the hatching time. With the application of nanotechnology, they will be stopped. 2- Opportunists are ambushing in different time points to misuse fish. Also, the guards might be ignorant. With the application of nanotechnology, guards are no longer required. 3- This plant is cost-effective too.

本研究利用RNA干擾與基因過度表現兩種方法,觀察基因表現對果蠅蕈狀體神經突導向的影響。我們以RNA干擾方式降低基因表現,標定dally、octβ2r、sifr與frazzled基因;而基因過度表現則選定frazzled基因。利用果蠅GAL4-UAS系統使神經細胞表現的綠色螢光蛋白,觀察神經突導向情形。由干擾果蠅腦部蕈狀體PPL1-α′2α2神經細胞上述基因,觀察到dally、octβ2r基因在降低表現後,此細胞分別呈現失去神經支配與異常神經支配。sifr基因在兩種不同RNA干擾序列下,表現出不同之結果,一是和wild type的神經突型態相似、另一則是失去神經支配。frazzled基因干擾後,細胞在蕈狀體α2區失去神經支配。frazzled基因在過度表現下,神經突和wild type相比,出現異常導向。綜言之,由我們研究發現透過操控基因表現,果蠅腦部神經突會產生異常的導向與神經支配,顯示果蠅腦部神經系統在分化或發育上,基因扮演極為重要的角色。

當渦們酮在一起-金狗毛蕨對渦蟲再生能力的探討
本研究在探討台灣金狗毛蕨萃取物對於渦蟲傷口再生的影響,中醫認為金狗毛蕨具有抗菌效果,因此本研究同時分析了其根莖與茸毛中的酮類和酚類成分含量,並測試了其抗氧化能力。研究發現: 1.50%乙醇萃取液,金狗毛蕨具有最高的總酚類化合物萃取量,且透過延長萃取時間至3小時,萃取量將提高。 2.其含有豐富的總類黃類化合物,特別是在50%乙醇或純水溶液萃取情況下。 3.95%乙醇或99%甲醇萃取的金狗毛蕨溶液,顯示出極佳的抗氧化能力。萃取液在稀釋至0.1%後,對渦蟲傷口的再生效果特別顯著,尤其是95%乙醇與99%甲醇萃取液。 4.渦蟲再生試驗主要觀察尾段長出眼點的時間,以95%乙醇萃取液以及99%甲醇萃取液的渦蟲再生效果最好,能夠明顯縮短眼點的再生時間。

在學製氧時,老師說近三十年的教科書多用紅蘿蔔做實驗,直到五年前,各教科書都改用金針菇,原來是第五十四屆全國第一名科展作品的貢獻。金針菇取代紅蘿蔔,是因為用量比較少嗎?還是反應比較快呢?我們很好奇這兩者的差異,希望透過實驗找出更快分解雙氧水的方法。查資料後發現,大多催化劑製氧效果都無法與實驗藥品二氧化錳相比,當然包括金針菇,但是二氧化錳屬於化學藥品,又是重金屬,對環境會造成汙染,要特別處理。經我們反覆研究實驗後,找到酵母菌能取代二氧化錳快速大量製氧,不但只需用低濃度的雙氧水,準備實驗材料又非常的方便便宜,這個發現除了可以用於國小、國中甚至高中的製氧課程,環保又經濟的實驗優勢,相信是無法被取代的!

探究食品添加劑在糯米粉糰中的增塑效果
為了解含氫鍵的食品添加劑對糯米粉糰所造成的塑化效應影響,自製拉伸機探討。於文獻探討中,我們找到了數篇文獻也在探討添加物對澱粉延展影響的問題,不過其製備方式略有不同。其一為將澱粉混合並熱壓做成薄膜;另一為將澱粉配置成凝膠液。我們基於可製成食品的方向進行研究,目前所得研究成果與論文的情形相似,氫鍵確實會影響澱粉團的能承受張力,冷卻情形也是變因。其中,添加劑劑量增加可達增塑效果。冷卻時間越長,麵條越脆弱,彼此間能承受的張力差也越大。冷卻溫度降低則使麵條所能承受的張力提高。
