與「擬」的距離-高中生線上社交與離線互動行為差異之研究

隨著數位科技的發展,線上社交平台已成為高中生日常生活的重要部分,其中非語言符號在溝通中扮演關鍵角色。本研究旨在探討高中生在線上與離線互動中使用非語言溝通元素的行為偏好及其動機。結果發現,高中生可能在即時通訊平台上表現出情境依賴性,多數參與研究的學生在不同社交情境中會根據通訊對象調整溝通行為,與長輩或「嚴肅人物」溝通時更傾向使用文字表達。另外,學生偏好使用表情符號來加強情感表達,但非語言符號解讀差異仍會影響效果,無法完全取代離線交流中的非語言情感傳遞。本研究有助於了解高中生在數位平台上的溝通行為,希望後續的研究者能夠更深入的研究。

短期睡眠剝奪對小鼠免疫系統的影響

現代社會中,睡眠剝奪已成為普遍問題,人們對其對免疫系統及整體健康的負面影響愈加關注。本研究使用特製的旋轉鼠籠讓小鼠連續72小時保持清醒,探討急性睡眠剝奪對小鼠免疫反應的影響。研究發現NK細胞與脾臟中的記憶CD8 T細胞比例明顯減少,顯示細胞毒性功能受損或記憶免疫反應下降。與此同時,抗炎細胞因子的表達增加,而促炎細胞因子和相關基因的表達則有顯著下調。此外,雖然觀察到B細胞比例有所增加,這可能是免疫系統在細胞免疫功能受損時,維持免疫穩態的反應。這些發現揭示了睡眠剝奪可能抑制免疫系統造成損害。本研究強調適量睡眠對維持免疫平衡的重要性,並指出睡眠不足可能促進慢性免疫問題的發展。在此基礎上,後續研究可探討短期睡眠剝奪與腫瘤及免疫系統的關聯,並延伸至長期剝奪的影響。

「解」不動了--當電解水遇到絆腳石

本研究探討在電解水過程中,添加非電解質(如蔗糖與甘油)對離子移動速率的影響。實驗以硫酸鈣粉筆為水溶液載體,搭配廣用指示劑觀察電極附近的顏色移動,分析離子的遷移行為。結果顯示,糖與甘油皆使離子遷移速率隨濃度上升而下降,原因包括溶液黏滯性提升、水合作用與分子的碰撞阻擋,使得離子移動速率變慢。 本研究並進一步比較甘油、葡萄糖與蔗糖三種非電解質的影響效果,結果顯示:儘管甘油溶液的電阻高於葡萄糖,但離子在甘油中移動速率更快,推測與甘油較小的分子結構、較弱的水合作用,以及特殊的潤滑性有關。此結果挑戰「電阻越大,離子移動越慢」的直覺印象。

Application of Carbon Aerogels in Lithium-Air Batteries

One of the main challenges with today’s batteries is their relatively low volumetric and specific capacities. The highest specific capacity can be achieved with lithium-air batteries, which use metallic lithium as the anode and typically some form of porous carbon as the cathode. To enhance performance, aerogels—among the world’s lightest solid materials—are ideal candidates for cathodes. Resorcinol-formaldehyde (RF)-based carbon aerogels, for example, serve this purpose well. In my work, I utilized two types of carbon aerogels as cathode materials: one derived from pyrolyzed resorcinol-formaldehyde polymer and the other a graphene-oxide-modified version of this carbon gel. I integrated the carbon aerogels I had pyrolyzed into lithium-air batteries to improve the cell’s performance, energy density, and capacity compared to cells using activated carbon. In my research, I examined the pore structure and surface properties of these materials in aqueous media using NMR (nuclear magnetic resonance) relaxometry and cryoporometry, exploring their impact on battery efficiency. I found that the graphene-oxide-containing sample's pores filled with water in a layered manner, indicating a more hydrophilic surface, which suggests a denser arrangement of oxygen-containing functional groups compared to the unmodified carbon aerogel. The pore sizes were reduced after adding graphene oxide, resulting in an increased specific surface area for the sample. Incorporating the reduced graphene-oxide-containing carbon aerogel enabled the creation of a more efficient, higher-capacity battery than with the RF carbon aerogel. This improved performance is likely due to the aerogel’s higher oxygen content and altered morphology. The increased oxygen content provides more active sites for oxygen reduction, meaning that a greater specific power output can be obtained from the battery.

A Study on Hybrid Electromechanical Actuators

An actuator [7,22,28,29] is a motion control mechanism. Depending on the type of actuator, it can convert one type of energy (e.g. chemical, electromagnetic, thermal) into mechanical energy. The field that laid the foundations for the realization of actuators is the field of electromechanics, whose evolution was common with that of actuators. Thus, a periodization of the electromechanics paradigm includes 3 major stages [7,6,25,28,29]: I.1830-1950 Old electromechanics. It is the period when the development of electric cars is significant, which imposed the appearance of classical or primary electromechanical drives. It was a generous nineteenth century, dominated by the scientific results of the triumvirate: Michel Faraday (initiator of fundamental empirical experiments in the history of electricity; the law of induction, of the principle of electric motor, of the magnetic circuit, initiator of electro-chemistry), James Clerk Maxwell, (the genius theorist who put into mathematical form the equations of electric and magnetic fields, as well as the connection between them), and Werner Siemens (engineer and capitalist genius manager who managed to exploit and validate the relationship research-technology-economic development), triumvirate that can be disputed in the sense that other scientists also made outstanding contributions to the history of electricity: Edison, Ampere, Ohm (to name but a few who do not exhaust a significant list). Industrial production of electric machines also appeared and the first signs that will announce the emergence of electromechanical actuators as a basis for military applications. II.1950-1970, Traditional electromechanics, in which electrical power drives appear, a theoretical and experimental development on the emergence of new material and electromechanical principles. Much military research (such as missile control or ship and torpedo control) influences and produces the transfer of applications in ordinary life, including the actuator subfield. III. 1970-2020, Avant-garde electromechanics, representing according to Thomas Kuhn's theory, a paradigm forcing [30]. It is worth noting the contributions of the new scientific revolution. - Specific technologies of miniaturization, by material deposition. - Elastomeric polymeric materials with the help of which it was possible to make electrostrictive actuators, - Very special means of investigation, mainly the development of microscopy, - Gradient of applications in the field of medical engineering, with outstanding contributions both in investigation and microsurgery, applications of actuators in biological micropumps, etc. [25,27,28,29].

Investigating the Effects of Temperature and Carbon Dioxide Levels on Nannochloropsis oceanica Using a Hemocytometer Counting Method

Climate changes that include ocean acidification and global warming are serious problems in the ecosystem, affecting marine phytoplankton, including Nannochloropsis oceanica. In the effort to further explore the impact of rising temperature and carbon dioxide (CO₂) concentrations on oceanic ecosystems, the phytoplankton Nannochloropsis oceanica was used as a model organism. This study explored the effect of temperature change and CO₂ concentration on the growth of Nannochloropsis oceanica, achieving 243 samples that were tested with three different temperatures (24 degrees Celsius (°C), 28°C, 32°C) and CO₂ concentrations (0 milliliter (ml)/min, 0.4 ml/min, 0.6 ml/min), utilizing a hemocytometer counting method. Results indicate that the CO₂ concentration has a significant effect on the population of Nannochloropsis oceanica. But the temperature doesn't affect a lot. The Nannochloropsis oceanica in the lowest temperature and highest concentration of CO₂ in its environment had the highest population growth, and in the highest temperature and lowest concentration of CO₂, it had the lowest population growth. Results show the serious negative effect of climate change on the cosystem and the importance of environmental protection. Population blooms due to excess CO₂ taking up ocean resources causing dangerous ecological imbalances.

The Maximum Area of N-gons within the Intersection Region of Two Congruent Circles

At the 61st National High School Science Fair of Taiwan, the first-rank paper "The Study of the Largest Area of Inscribed Triangle within the Intersection of two circles" was presented. The authors discussed several properties of maximum area of inscribed triangles within intersection regions of two congruent circles. They only claim their results but without providing a rigorous proof. However, we give a proof by showing the convergence of the iteration of finding the largest height. Subsequently, we offer new methods to approach the problems such as the trigonometric identities, Jensen's Inequality to prove the maximum area of triangles and quadrangles within the intersection region of two congruent circles. Finally, we determined the maximum area for the case of n-gons. We conducted further research and discussion on this issue. In the future, we hope to prove why the maximum area of n-gons within the intersection region of two congruent circles occurs when there are two points on the intersection points of the two circles. We aim similar problems in the three-dimensional space, namely the maximum volume of tetrahedron within the intersection of two unit spheres.
