Conspiracy theories are generally perceived as irrational, absurd and as having a negative effect on our reputation. Yet some people do not see them as such. This may lead us to wonder why and how an individual would come to believe or support such statements. In this work, the primary goal is to obtain the level of absurdity of various conspiracy theories so that they can be used in experiments designed to test Williams' “Strategic Absurdity Hypothesis”. In addition, this study attempts to demonstrate the link between conspiracy mentality and feelings of ostracism. In this research, I analyzed a group of 47 participants recruited via social networks in May 2023. The survey collected their demographic information, their conspiracy mentality, their feeling of ostracism, their knowledge of conspiracy theories and their perception of absurdity toward them. The results were analyzed using correlations and linear regressions. The results show a negative correlation between conspiracy mentality and the perception of absurdity for most theories. In other words, the higher a participant's conspiracy mentality, the less absurd the theory is perceived to be. Therefore, hypothesis (I) is partially supported. On the other hand, hypothesis (II), which says that ostracism predicts conspiracy mentality, is not supported by the results. These results are in line with Williams' “Strategic Absurdity Hypothesis” and Sterelny's signaling theory, explaining that an individual, by expressing agreement with a conspiracy theory typically perceived as absurd, damages their reputation in the eyes of others to show that they belong to the group. However, for the theories relating to COVID-19 and climate change, the conspiracy mentality does not predict the vision of absurdity, suggesting that their currentness and media coverage influence whether they are used as signals. The literature does not fully agree with our results and still presents very divergent opinions regarding the links between feelings of ostracism and conspiracy mentality. Indeed, it remains difficult to determine whether conspiracy mentality influences ostracism or vice versa. In conclusion, this study provides new ideas for future research on the origins and impact of the conspiracy theories.

Recently,thefeedpricesforlivestockfarmshavebeencontinuouslyincreasing, while the prices of calves have been declining, leading to many livestock and dairy farms facing financial losses. If livestock farms are affected by diseases such as foot-and-mouth disease, they suffer significant losses. This is because reducedproductivityinlivestocknotonlyaffectstheirproductionbutalsoentails substantial costs for vaccines and treatments. Therefore, there is a need to explore how to effectively prevent diseases, focusing on common diseases in cattle such as subclinical mastitis and mastitis, and alleviate the burden on farms economically and environmentally. This study aims to investigate the production of bacterial growth-inhibiting straw bedding using substances such as illite and charcoal to contribute to disease prevention.

研究使用化學液相沉積法製作摻鋁氧化鋅(Zn1-xAlxO，x=0、2%、4%、6%)奈米線於染料敏化太陽能電池上，研究摻鋁氧化鋅奈米線之晶體結構、光學及染料敏化太陽能電池特性。結果顯示摻鋁濃度4%之氧化鋅奈米線具有最佳(002)結晶相及奈米線直徑及長度，也具有最佳太陽能參數為:開路電壓0.683V、短路電流4.56mA、填充因子52.3及轉換效率1.62%。因為鋁離子取代鋅離子時，可改變氧化鋅晶格結構降低缺陷密度，使奈米線的直徑及長度增加，提升染料的吸附量，並降低能隙使電子與電洞復合機率降低，大幅提升光電轉換效率。然而摻雜過量的鋁離子6%時反而導致晶格產生扭曲，導致晶格內缺陷密度增加。從這研究可了解摻雜鋁元素對於氧化鋅奈米線之染料敏化太陽能電池影響，未來希望能研究其他參數進而改善染料敏化太陽能電池之發電效率。

本研究探討臭黃荊葉製作「神仙豆腐」的科學原理與應用，重點包括：(1)以碳酸鈣取代傳統草木灰作為安全凝結劑，最佳比例為9克葉粉、1克碳酸鈣、500毫升水，凝結效果良好無異味。(2)透過碘滴定法發現臭黃荊與其他飲品、藥材比較，抗氧化能力優異。(3)開發創新食品神仙桂花球，雙層結構設計改善臭黃荊風味與接受度。(4)設計茶包配方，以臭黃荊為基底搭配薄荷、菊花等食藥材，兼具養生功效與適口性。實驗中為了解決科學問題，自製門形抗壓機、滴定終點判讀器、無氧攪拌器等特殊工具；還發現空氣接觸量不一定影響抗氧化力、新鮮葉片抗氧化優於乾燥葉粉等結果。最終結果顯示臭黃荊具有養生食材的開發潛力，突破傳統製作方式與風味限制。

本研究利用注射器與蠕動泵浦穩定產生直徑 3mm 液滴，並以高速攝影觀察其撞擊行為。實驗發現液滴撞擊乾燥固體表面時，表面粗糙度對接觸角影響不明顯，親水與疏水材質則導致「錨定」或反彈翻轉。進一步研究顯示，液滴撞擊濕潤表面時，親水材質易拉緊液滴表面使其回彈，超疏水碳黑表面則造成液滴彈跳分離。針對濕潤IC晶片進行熱交換分析，結果指出高韋伯數液滴可打破錨定產生飛濺與擴散，顯著提升散熱效果，當韋伯數達193.3時降溫幅度達8.6°C，效能較低韋伯數提升近80%。本研究證實韋伯數與表面性質對液滴撞擊行為具關鍵影響，對液冷與熱管理技術應用具有潛力。

本研究的目的是探討巧克力遊戲，切到剩1塊巧克力，對方無法再切時，就贏得遊戲，巧克力紙板的形狀及尺寸與遊戲獲勝的關係。 研究結果發現：巧克力紙板是正方形，後行者切出正方形給先行者，就會贏得遊戲。若正方形的邊長為A，先行者切給後行者n條，先行者贏的比率的分母為(A－1)＋(n－1)2，分子為(A－2)＋(n－1)2。 巧克力紙板是寬為A，長為B的長方形，先行者切出正方形給後行者，就會贏得遊戲。若A≦2，後行者贏的比率的分母= A＋B－2；若A＞2，後行者贏的比率的分母=A×(A－2)＋B。 此遊戲獲勝的關鍵是｢正方形｣，先行者或後行者只要能切出正方形尺寸給對方，就會贏得遊戲。

科技海綿（又稱環保海綿）能在不使用清潔劑情況下去除污漬，被認為是環保用品。但在使用過程中會逐漸變小後消失，令人疑問的是：它真的溶解了嗎？是否會對我們和環境造成影響？ 為此針對以下幾點探討： 一、探討其去污原理，並以顯微鏡觀察其纖維結構。 二、觀察使用後水體，確認使用後是否會釋放出塑膠微粒。 三、使用三聚氰胺檢測劑，測試使用後的水是否含三聚氰胺。 四、以使用過水種植綠豆與水蘊草，觀察生長情形，評估對生物的影響。 五、檢測市售牙齒美白橡皮擦，使用後是否釋放三聚氰胺或塑膠微粒，提醒消費者注意 安全。 透過實驗，期能探討科技海綿是否真的「環保」，並進一步了解其對生態環境的影響。

Wind energy is one of the most promising and rapidly growing sources of renewable energy, although maximizing its efficiency while minimizing noise remains a challenge and limits its widespread adoption. The emergence of toroidal propellers, which have gained popularity for producing comparable thrust levels to traditional drone propellers while producing less noise, could mitigate this. This study aimed to develop a small-scale toroidal HAWT and compare its power and noise output to a conventional rotor design under similar wind velocity conditions. 15-centimeter diameter models of the toroidal and conventional rotors were created in Fusion 360 and simulated using Ansys Fluent to identify the significant aerodynamic characteristics that positively affect the blades’ power coefficient. The toroidal design with the greatest simulated power output at low tip speed ratios (TSRs) was then 3D printed and physically tested in a wind tunnel against the control rotor. The experimental results confirmed that the toroidal design had greater power coefficients at lower TSRs compared to the control rotor. The toroidal rotor started operating at a wind velocity of 3 m/s compared to the control rotor’s 6 m/s, which indicates superior start-up characteristics. While the toroidal rotor produced half the power output of the control at the highest tested wind speed of 7 m/s, it emitted 18 decibels less noise and showed a reduction in discernible noise between frequencies of two to five kilohertz. The results from this study show its potential in low-noise wind turbines within low-wind velocity environments.

動物的學習能力與思考能力為判斷動物智力重要標準。本研究利用朱文錦的制約行為探討其學習能力、記憶能力、辨色能力與數感能力。研究以自製六邊形場地訓練朱文錦辨認顏色、測量其記憶時長與辨色精確度，並訓練其辨認數量多寡，以測定朱文錦數感能力。實驗結果發現朱文錦能辨認紅色，並能被訓練使特定顏色與食物產生連結，在紅色區域滯留較長時間，證明朱文錦可被訓練產生制約反應。停止訓練後其記憶力可長達7週，記憶強度與時間成高度相關。在數感測驗中，發現朱文錦具有可分辨數量的能力，且分辨能力與數量的比值與差皆有相關。本研究證明，朱文錦具學習能力，記憶力長達七週，辨識顏色精確度可達明度差±40，並具有一定數感能力。

為觀察氣流流經物體表面不易流動的現象，我們設計製造風洞實驗裝置。將筆芯墊在金屬片上，測量筆芯被吹動時的驅動速率，繼而變更筆芯的高度與水平位置，測量筆芯被吹動之驅動速率。由數據作圖可看出在風洞管下半部，筆芯驅動速率會隨著高度以乘冪減少，也就是從底層往上的流速是乘冪函數增加，與文獻之圖形類似。同時從數據作圖分析中也可看出筆芯越細，隨高度增加時，驅動速率較快變小。而筆芯超過風洞管一半鉛直高度後，數據曲線不如預期，故又繼續研究金屬塊破壞層流之效應。在底層放平行條狀物(簡稱肋條)，用筆芯來看出氣流的擾動，測出驅動速率有些區域大有些區域小，表示障礙物引起二次流的紊流並不是流速變快，是屬於擾動式的。
