氣候變遷加劇了蚊媒疾病對全球公共衛生的威脅,迫切需要創新的解決方案。在台灣,登革熱的傳播主要由蚊蟲滋生所致。為了解決此問題,我們設計了一款三層結構的3D 列印誘蚊器,包括吸引懷孕雌蚊產卵的誘餌層、捕捉蚊蟲的黏膠層,以及防止異物進入的保護層。該裝置成本低、易製作且不需要外部電力,特別適合在資源有限的地區部署。 我們結合校園監測站每日捕捉的蚊蟲數據與氣象站提供的溫度、濕度和降雨等環境數據,運用SARIMA 與隨機森林混合模型進行分析與預測。SARIMA模型負責捕捉蚊蟲數量的季節性與長期趨勢,而隨機森林模型則處理環境變數與蚊蟲密度之間的非線性關係。此混合模型不僅提高了預測精度,還能解析蚊蟲的生態模式,進一步指導誘蚊器的最佳配置。此外,我們還開發了紅外線感測系統,即時偵測蚊蟲活動,為監測提供精準數據。 為評估氣候變遷的影響,我們模擬了不同全球暖化情境下的蚊蟲密度變化趨勢。結果顯示,隨著溫度上升,蚊蟲密度呈現非線性收斂趨勢,但正相關性依然存在,強調了氣候變遷可能帶來的潛在危害。我們還開發了一個網站,用於即時呈現蚊蟲密度預測,幫助政策制定者和公共衛生機構有效應對疾病防控挑戰。 本研究與聯合國永續發展目標(SDGs)中的SDG3(良好健康與福祉)及SDG13(氣候行動)高度契合,展示了結合3D列印、機器學習、即時感測和網路技術應對蚊媒疾病的創新潛力。此系統提供了一個可持續的全球蚊蟲控制模型,為公共衛生、疾病預防及流行病學的未來創新奠定了堅實基礎。

DSUP: New Research On The Implementation Of Radioresistance In Cellular Systems
In radiation treatments and manned interplanetary space travel, radiation is one of the biggest problems. The radiotolerance of cancer cells makes it necessary to apply high doses to surrounding healthy tissues by subjecting the cells to heavy stress. With regard to space travel (which involves a minimum travel time of 6 months) (1,2) the danger concerns cosmic radiation which is capable of inducing genetic mutations that, in turn, can evolve into very serious pathologies, such as cancer, damage to dendrites consequently compromising synapses. The project is aimed at developing a technology that can address these issues and aims to make human DNA radioresistant. This study involves a nucleosome-binding protein called DSUP (Damage Suppressor Protein) unique to the tardigrade Ramazzottius Varieornatus and the subject of its radioresistance. It can theoretically safeguard genetic material damaged by radiation. *Internship theme at the Pino Torinese Astronomical Observatory and the DISIT-UPO Environmental Molecular Toxicology Laboratory. The study molecule: Numerous tests have been carried out through the "in silico" approach geared toward mathematical modeling of its protein structure and complex mechanisms of action simulated through artificial intelligence systems, followed by direct laboratory analysis involving biosynthesis of DSUP by genetically modified bacteria and related tests. Both approaches, applied synergistically, aim to make it accessible and useful for the protection of human health.

Utilizing Flavonoids From the Invasive Species Pilea Melastomoides and Daucus Carota as Well as the Protein PTK-2 to Create a Skin Gel Aimed for Burn Wound Healing.
Burns are a major global health concern especially in developing countries like 印尼, where southeast asian women experience the highest burn incidents globally. Burns can cause severe physical and psychological impacts, with treatments that are critical to reduce complications. This study focuses on the development of organic, cost-effective burn gels using flavonoid compounds which are Quercetin and Myrecetin which are taken from pilea melastomoides leaves, a wild 印尼n plant and carrot (Daucus Carota). These skin extracts aim to accelerate wound healing, minimize pain and prevent infection. The gel formation involves extracting active compounds using 96% ethanol as it has been effectively used for extracting a wide range of bioactive compounds to preserve their quality by preventing microbial contamination, and ensures a high yield of active ingredients suitable for topical applications. Then it goes through a process of Phytochemical screening to confirm the presence of flavonoids by using the Shinoda test. The formulation process included dissolving the HPC-m (Hydroxypropyl Cellulose) as a gelling agent, then adding plant extracts (pilea melastomoides leaves and carrot), as well as combining other ingredients such as propylene glycol, sodium benzoate, sodium metabisulfite, and disodium EDTA. The gel was stirred thoroughly to ensure uniformity and left at room temperature for 48 hours to attain the required consistency. The gel that was formatted went under various quality assessments, first being organoleptic testing. This test is used to evaluate its physical characteristics which includes color aroma, and consistency which confirms a stable dark green appearance and a natural strong scent from the plant extracts. The homogeneity test is used to verify the uniformity distribution of active compounds across the gel, to ensure a consistent efficacy. The pH test showed the gel’s acidity level which remained the safe range for skin application. Additionally, the spreading ability test demonstrated the gel’s excellent application properties, with consistent results across trials. Subsequently, the in silico analysis was conducted to predict the behaviour of specific flavonoid compounds used which is the myricetin and quercetin, highlighting their potential anti-inflammatory and antimicrobial activities. Further bacterial contamination tests confirmed the gel’s antimicrobial efficacy, reducing the risk of infection in wounds. This study demonstrates that the gel, formulated with pilea melastomoides leaves and carrot skin extracts, effectively utilizes flavonoids and other phytochemicals to reduce inflammation, promote tissue regeneration and retain moisture, which fosters an optimal condition for wound healing. This organic and sustainable burn treatment utilizes locally sourced ingredients, providing a natural solution that speeds up recovery, reduces pain and prevents infections. The results highlight its significant potential for wider healthcare use, especially in resource-limited environments.

Wetting Tracing Paper—Fiber Porous Media Curling Behavior and Mechanisms
This research presents a novel approach to understanding the curling and uncurling behavior of tracing paper when exposed to water, identifying limitations in traditional diffusion-based models like Fick’s second law. While Fick's model adequately represents the uncurling phase, where water content is stable, it falls short during the curling phase due to its inability to account for dynamic changes in diffusivity. Our study identifies capillary action, modeled through Richards' equation, as the primary mechanism in the curling phase, where diffusivity varies with water content due to capillary-driven water movement through the paper's porous structure. Experimental data align well with the Richards' equation model, highlighting a saturation point where curvature peaks, governed by evaporation's impact on moisture balance. To simulate this phenomenon, we developed a finite difference approximation scheme based on Richards' equation, discretizing the spatial domain for detailed control over moisture dynamics and incorporating the Robin boundary condition with virtual points. This approach, combined with evaporation considerations, produces simulation results consistent with observed data, emphasizing evaporation’s role in steady-state moisture gradients and the subsequent deformation mechanics. Our findings further reveal that factors like paper thickness, temperature, and salt concentration significantly influence curling behavior. We established linear correlations between peak time and thickness reciprocal, as well as between peak curvature and thickness squared, supporting theoretical models. Temperature affects both peak curvature and curling rate due to changes in viscosity and surface tension, and higher temperatures prevent full uncurling due to sustained evaporation effects. Increased salt concentration heightens peak curvature without altering expansion ratio, suggesting additional variables in play.

Decoding Climate Resilience: Functional Profiling of Protein Phosphatase 2C Family Genes for Abiotic Stress Tolerance in Rice
Problem • Rice is the primary cereal crop consumed by nearly half the population worldwide • By 2050, there will be a 50% increase in demand for rice • The world’s poor populations depend more on rice, both for income and consumption, than any other food. Rice is the single-largest source of employment and income for rural people • Worldwide, 51–82% of agricultural crop yield is lost annually due to abiotic stress due to climate change • Climate change causes extreme temperatures, erratic rainfall, dangerous droughts, and increased salinity from rising sea levels Solution • To adapt to abiotic stress, rice has intricate signaling pathways, particularly those mediated by the phytohormone abscisic acid (ABA), that cause an increase in stress tolerance • Clade A genes of the Protein Phosphatase 2C (PP2C) gene family are known to be negative regulators of the ABA signaling pathway. • “Deleting” these genes activates the ABA pathway and increases stress tolerance in rice without inducing stress CRISPR gene editing technology is the ideal solution Research Goal • While the role of PP2C genes in stress response is recognized, there is a gap in understanding the specific genes within this family that contribute significantly to stress signaling. Furthermore, there is a need for a detailed investigation into the effects of targeted CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) genome editing on rice stress response pathways.

利用體外測試方法探討生醫水凝膠與材料表面附著性質之關聯
Investigation of the relationship between biomedical hydrogels and surface adhesion properties using in vitro testing methods
醫療級水凝膠在注入人體後容易因運動行為而產生位移,因此需要體外測試方法來評估水凝膠的附著性,以製備適合不同部位使用的水凝膠。本研究設計兩種測試方法來模擬水凝膠在人體的斜角流動狀態和旋轉流動狀態的位移,藉此推斷水凝膠施打入體內後的變化。本研究採用兩種不同黏性的水凝膠和不同粗糙度表面如人工皮、陶瓷和金屬來模擬人體部位的接觸面,探討水凝膠的附著性質。斜角流動測試下,黏性高的水凝膠在陶瓷和金屬 30°、45°及90°的斜角下幾乎不會流動,黏性低的水凝膠則會隨著角度的增加而流速加快。陶瓷粗糙度最高,水凝膠在其表面上附著性質較強。旋轉流動測試下,高黏性的水凝膠在模擬跑步時都具穩定性,而低黏性則只適用於較穩定的步行狀況。體外測試方法能區分不同黏性水凝膠的附著性質,說明此方法可作為篩選適用的水凝膠的依據。
