探討在秀麗隱桿線蟲中IFE-1經由sRNA路徑對於精子生成機制的影響

sRNA在各種物種的精子功能中起著至關重要的作用。在秀麗隱桿線中,當缺少精子相關的sRNA「ALG-3/4 26G sRNA」會導致其在25度時不孕。此外,IFE-1是人類真核轉譯起始因子EIF4E的直系同源基因,主要表達於雄性生殖細胞系統中。在先前研究中我們觀察到當「真核轉譯起始因子IFE-1有缺陷」或「精子缺少相關sRNA」時,亦會導致精子具有缺陷。由於三者的相似性,我們認為IFE-1和26G sRNA的生成路徑有關。因此我們假設IFE-1參與協助酵素NYN-3辨認並切割msd-1 mRNA模板後促進26G sRNA生成。我們使用Western Blot、IP、螢光顯微鏡等方法,探討了IFE-1和MSD-1::GFP的關係,發現在ife-1正常的情況下,高溫對於MSD-1::GFP的表現量沒有影響。並且因該蛋白只表現在公蟲精子,我們可以推論msd-1:gfp 只作用於公蟲精子。而此疑似可正向調控基因表現的26G sRNA,有望發展成有別於過往sRNA藥物抑制基因表現的一種新基因治療方法。

自監督學習在臺灣手語辨識上之應用研究

在臺灣手語辨識,先前研究所使用的監督式學習需要大量標記樣本而限制可辨識詞彙量。為此,本研究借鑒自然語言處理領域中BERT 的遮罩想法,將未標記手語影片隨機遮蓋部分幀數,並讓模型學習預測被遮蓋的幀數以學習臺灣手語的特徵,並透過遷移學習來訓練辨識模型,此作法可克服現有臺灣手語資料缺少的問題。經過實驗,本研究訓練之詞彙辨識模型達成了242 個詞彙量,94.8%的準確率。 此外,先前研究皆未在手語句子翻譯上有成果。因此本研究基於預訓練模型,整合設計手語翻譯的系統,實驗中,系統在100 個句子的翻譯表現達到88%的準,且BLEU-4 分數取得20.98,證明自監督學習的方式在手語辨識、翻譯上是有效的。並展現出樣本需求少與辨識詞彙量可輕易擴大的潛力。

「果」然有酒,過剩水果的發酵新生機

在這個計畫中預計透過發酵作用,將過熟或剩餘的水果轉化為酒精,以實現資源回收與環境保護。我們選擇含糖量較高的水果(如鳳梨、火龍果、柑橘、葡萄等),壓碎後加入酵母菌,在適當溫度下發酵,促使糖分轉化為酒精與二氧化碳。發酵完成後,利用蒸餾法獲得初步的蒸餾酒精。 此外,測試不同水果的酒精產量、溫度對發酵效率的影響,並分析蒸餾後酒精的濃度與產率。我們最終將驗證所得酒精的殺菌效果,探討其應用於日常環境消毒的可行性。由於有效消毒的酒精濃度需達 75%~78%,我們將進行多次蒸餾,提高酒精濃度,並記錄細菌與微生物的活動情況,以確認其可用性。此結果不僅能減少食物浪費,還能運用科學方法將剩餘水果轉化為有價值的清潔資源。

Development of MBR, CO2 absorption ball

We invented the Midori which means green Bioreactor (MBR), beads of euglena and other microalgae fixed in calcium alginate that absorbs carbon dioxide (CO2). We examined the effect of 19 different solutions and two different organisms on MBR cultivation. Surprisingly, when the MBR was supplied with carbon dioxide or cultured with yeast, they became drastically darker green. Chromatography revealed this green color to be that of microalgae such as green algae or Euglena because chlorophyll a and chlorophyll b were detected. Under sunlight, MBR absorbed CO2 and the absorption rate was 1.5 L CO2/day/1L of MBR. Furthermore, when we put MBR in the water tank, they increased the amount of dissolved oxygen without polluting the environment. These results indicate that MBR can absorb CO2 by photosynthesizing without leaking out the inside microalgae.

殊途同歸─不可思議的七線共點

本研究探討三角形中線段共點的幾何性質,特別是與奈格爾點相關的七線共點現象,這七條直線包括三條特定的作圖線、三條周長平分線、以及內心與重心的連線。研究動機源於對奈格爾點定義及其作圖方法的探究。研究過程中,我們透過Dussau作圖法、三角形性質及解析幾何等方法,從已知條件推導出相關的幾何性質,並進行了驗證。研究發現這三條作圖線分別與三內角平分線平行,可視為內心在位似變換下的映射。本研究亦探討此類作圖法是否可遷移應用至其他三角形特殊點(如內心、重心)。這些發現證明了即使直線的構成方式看似複雜或「殊途」,最終也能「同歸」於同一個點,展現了幾何的奧妙。

探討影響臺灣周遭海域波浪能蘊藏量的關鍵因素 English Title:Investigation of Key Factors Influencing Wave Energy Potential in the Surrounding Waters of Taiwan

團隊透過分析臺灣台灣周遭八個處海洋浮標測站資料,自2021年1月到2024年10月為止之示性波高、平均週期、平均風速、海溫等資料間之相關性,並試從不同位置測站之海洋條件與大氣因素,來綜合探討影響臺灣周遭海域波浪能蘊藏量的關鍵因素。並透過分析海溫與波浪能變化的關係,試圖瞭解全球暖化平均海溫上升,對臺灣周遭波浪能蘊藏的變化趨勢。 團隊發現影響臺灣周遭海域波浪能蘊藏的因素,除了季節性季風的影響,黑潮主流以及澎湖水道的黑潮支流湧升流,也都 可能 是影響臺灣周遭海域波浪能蘊藏的重要因素。團隊也發現,在臺灣周遭海域波浪能蘊藏與海溫變化有負相關的趨勢,此現象與臺灣中央研究院針對過去70年,全球波浪能的變化趨勢並不一致。其原因可能是臺灣所屬地理位置環境的關係,也可能是分析的數據資料僅有4年無法準確看出趨勢變化。

Artificial Intelligence Sensing Technology for Blinds Path Findings

Over 30 million souls live in a world of darkness, a number greater than the populations of both Norway and Sweden combined. Every individual deserves the chance to embark on a journey across our magnificent blue planet. Yet, regrettably, little has been done to assist them. With this project, we’re lighting the way for the blind to explore our beautiful world independently, breaking free from dependence and embracing boundless horizons. In order to put our theory of the project into practice & explore the use of artificial intelligence & computer science, we started by collecting the required materials for our project such as micro-controllers, sensors, a pair of glasses, a laptop, and a miniature camera. Then we moved onto creating the project itself in which the digital software programmed onto the hardware plays the key-role, as the sensors and the camera will record the details and information from the surroundings and send it to the laptop for further processing. The camera would be the backbone of our project, as it will stream real-time footage to the laptop which will be analyzed by an open-source object detection model ‘YOLOv8’ for identifying objects. After finishing the base model of our project, we tested it in-front of objects such as toy cars, bikes, people, etc, and the results of the object-detection would be shown on the laptop. To observe this data, we created a device which has different modules and integrations for different functions. For example, we will use our camera and then stream it onto a laptop so the reading and the data can be processed on the laptop by AI using YOLOv8. As mentioned in the start, many people do not possess the ability to see, to assist them we have thought of this device which uses all readings and its analytical skills to analyze data and help them navigate, travel or simply, live a better life.

蒙提霍爾問題中選擇期望值與多變數衍伸性操作之研究

典型蒙提霍爾問題(Monty Hall Problem)(李永乐 [1]),又以別稱「三門問題」廣為流傳,是一項源於賽局理論的機率謎題,得名於《Let's Make a Deal》節目主持人。遊戲規則表明,在三扇門後共有一件獎品,參賽者選擇一扇門後,主持人會打開另一扇無獎品門,接著參賽者有權選擇是否換門,此時若選擇換門則勝率將提高到 2/3,這對許多人而言並不直覺,這也正是這個問題的有趣之處。 本篇研究由典型蒙提霍爾問題出發,逐步將結果推廣至七變數組方程式,並進行多種開門規則、非全同機率門,與多回合換門機制、中獎個數機率分布之討論。最終推導出玩家各執行策略及與之對應之期望值和機率函數方程,除強化已知文獻結果之泛用性外,也使典型三門問題具有更大的調整自由度。

綠茶煉金術:以綠色科技打造奈米金與奈米銀

奈米科技已廣泛應用於醫療、能源和感測技術,而奈米金屬粒子更因其獨特性質備受關注。本研究探索了一種環保、無毒的方法來合成奈米銀與奈米金,減少傳統化學還原劑對環境的影響。我們首先嘗試用檸檬酸鈉來還原銀離子,合成不同尺寸的奈米銀粒子,並進一步使用綠茶萃取液取代化學還原劑,以開發更天然的合成方式。為了測試奈米銀的抗菌效果,我們將其應用於大腸桿菌與黴菌,發現奈米銀能有效抑制大腸桿菌的生長,但對黴菌的效果較弱。最後,我們利用綠茶萃取液合成奈米金,證明這種綠色方法能應用於不同金屬奈米粒子的製備。這項研究顯示,我們可以以更環保的方式合成奈米金屬粒子,未來或可應用於醫療、感測技術及其他高科技領域。

HandExo

Stroke is a very common disease, almost a national disease. In terms of stroke frequency, 匈牙利 ranks second in the world. Every year, 40-50 thousand people become paralyzed or permanently injured as a result of cerebrovascular disorders. This number is three to four times higher than in developed countries. Almost every Hungarian family is affected! Of course, saving the life of someone who has a stroke is the most important thing, but rehabilitation is also very important, since only with the help of a physiotherapist will the patient be able to live a full life.

Autonomous Ecosystem Surveillance Robot

Our project, the Autonomous Ecosystem Surveillance Robot, aims at closing the aquatic gap in biosecurity measures by including several functions, such as water quality monitoring, aquatic species monitoring, and seabed topology surveillance. Several instances have shown the need for such a system, as demonstrated below. The United States Corps of Engineers completed an electrich fish barrier in the Chicago Sanitary and Ship Canal in 2002, in order to prevent the invasive Asian carp from moving into the Great Lakes. The introduction of the Asian carp into the Great Lakes would be an ecological disaster, as the Great Lakes provide an ideal habitat for the carp to proliferate, choking out native fish species that exist there. This would result in a major loss for the fishing industry in the area. One of the Great Lakes, Lake Erie, suffers annual algae blooms threats, which affect up to 12 million people in the Great Lakes region of the United States and Canada. These algae blooms are caused by runoff pollution, which occurs when rainfall washes fertilizer and manure from farmland into Lake Erie, fueling algae that can make water toxic to humans and animals alike. In addition, there are many existing customs regulations around the world that are set in place to ensure biosecurity of national ecosystems, such as in Taiwan, where it is illegal to bring pork from abroad. Despite this, there still exists a very large gap in biosecurity measures; that of the aquatic nature. Through these three functions, we have the ability to protect local aquatic biodiversity via the ability to detect invasive species, therefore allowing authorities to properly deal with them. This allows less harmful measures to be taken against them, thereby limiting collateral damage to endangered native species. Coupled with the ability to map bodies of water, the Autonomous Ecosystem Surveillance Robot is an extremely potent tool to preserve aquatic biodiversity and to ensure biosecurity of local waters.
