海洋污染是本世紀最大議題之一，其中聚苯乙烯為最大量的塑膠微珠汙染，危害許多的海洋生物，影響海洋浮游藻類的基礎生產力，為了瞭解塑膠微珠以及其降解物對浮游藻類的影響性，本實驗選擇海洋中碳酸鈣沉降最多的鈣板藻進行研究，並探討塑膠微珠與其降解物對海洋生態的影響，利用流式細胞儀研究塑膠微珠(聚苯乙烯)和塑膠微珠降解物(苯乙烯單體)對鈣板藻數量、細胞複雜度、細胞大小、葉綠素含量等多重影響性，並利用質譜儀方法分析苯乙烯在細胞中和細胞外增加或減少的含量。

Carbon Monoxide is a very toxic and dangerous that threatens our life and can cause sudden illness and death. It is the most abundant, by mass, pollutant gas generated by the engine due to the lack of oxygen and thus presented in our lives. It is true that the oxidation catalyst absorbs carbon monoxide from the exhaust of cars during combustion. But that is not enough, the catalyst is only effective when the exhaust temperature is high (more than 400°C) which is not available in a short path. To protect ourselves from this toxic gas, we must find solutions and innovative ideas to fulfill this objective. And this is how our project was created. Our focus in this project is to create a filter that can absorb carbon monoxide using the minimum of energy possible. It will be more efficient unlike the traditional method that not only needs high range of temperature (higher than 400°C) but also takes a long period for the reaction to occur.

槍蝦閉合大螯所發出聲響為海洋珊瑚礁生態系中最主要的聲源，其聲音受多項環境因子影響，具有分析珊瑚礁生態系健康程度的可行性。本研究利用基隆潮境海域蒐集到的高時間密度採樣資料，嘗試分析槍蝦聲響在不同時間尺度下的變化與水溫、光度之關聯性，比較不同觀測期間與深度之資料，了解槍蝦聲響之特性。 研究結果顯示槍蝦聲響在長時間尺度下與水溫呈現高度正相關，且相同觀測期間、不同深度的兩筆資料變化趨勢相似；但相同深度、不同觀測期間的紀錄不僅變化趨勢與季節差異相關，整體數值也不同。槍蝦聲響每日亦具有規律的晝夜週期性變化，在清晨、黃昏出現高峰，白天期間與光度呈現負相關，夜晚期間與水溫高度正相關。最後，聲響峰值出現時間與日出日落時間最為相關，不同季節下之晝夜長短差異更造成顯著影響，不過仍會受水中實際接受到的光度影響。

在本實驗中，我們亟欲了解木星大紅斑其周圍不穩定之形成機制，意即探討大紅斑渦旋本身與其周邊風切帶之互動情形。第一、我們討論了風切帶之形成：有別於前人研究，我們使用全球準地轉淺水模式，在準地轉平衡的狀態下，渦漩會逐漸合併並緯向延伸，最終得出行星風系條帶狀僅為低頻波所產生之效應，且自轉越快帶狀越明顯；第二、透過克希霍夫渦旋理論，大紅斑始終能保持橫向的橢圓形結構且長軸不會旋轉係因為風切帶之加速效應；第三、我們使用淺水模式進行模擬實驗，發現大紅斑之非對稱西側擾動形成原因有二：一為大紅斑對風切帶之加速，以及木星低緯度風速較快加上風切帶之間具有渦度梯度形成之正壓不穩定效果。二來緯度越低則行星渦度越低，慣性不穩定易形成，即力學能差異越大不穩定越易形成，而此部份我們也以水工實驗展示。

本研究利用光柵繞射原理，結合慣性振盪之單擺，探究震動造成繞射光點間距變化關係，以光點振幅測量震動，建立以光學繞射變動結果顯示結構震動之響應關係。先確定光柵片旋轉、擺角改變對於繞射光點位置偏移，並以GeoGebra軟體分析函數關係，接著測量實際結構震動之加速度與光柵繞射光點位置的動態變化關係，藉此分析地震造成建物擺動時，光柵繞射光點間距變動的關係與趨勢函數，並由訊號反應建立結構震動之繞射光點振幅變動的響應關係。以標準震動訊號產生平台，量化之振動訊號強度，測量出本研究裝置在二維平面之地震訊號測量之表現，獲得二維震動訊號方向分量之關係。並以OBSPY程式分析裝置所測量之震動頻譜圖，確認繞射光點振幅變動可顯示地震訊號之特徵頻譜，更進一步採用Python開發繞射光斑即時影像追蹤軟體，成功透過裝置分析環境的震動響應。未來希望能微小化裝置，以監測建物震動，作為區域範圍測量地震對建物影響之發展基礎。

在暖雲的形成過程中，吸濕性凝結核佔有舉足輕重的位置且在大氣層中常會有不同種類的凝結核。本研究以自製的減壓雲室瓶模擬絕熱膨脹情況，並探討不同凝結核之成雲效果。減壓使凝結成長的效果在消光量的測量上符合比爾定律。而且利用絕熱膨脹估計出本系統在0.85 atm環境下每立方公尺的液態水含量LWC大約落在1.9~2.1公克，0.93 atm環境下每立方公尺的液態水含量LWC大約落在0.3公克，表示本實驗方法能擬合絕熱膨脹過程。且0.85大氣壓下，氯化鈉與線香粒子的成長可以達到1.68至1.94μm；硫酸銨粒子成長則達到1.01~1.12μm。而0.93大氣壓下，硫酸銨粒子成長則是0.77~1.04μm。另外，比較水溶性粒子與固態微粒化學性質，發現水溶性粒子如氯化鈉和硫酸銨的確較適合做為水氣之凝結核。

The following issues associated with soil affected by wildfires were identified: First, there was a significant decline in the populations of anaerobic and aerobic soil bacteria, which play a critical role in the decomposition and cycling of organic matter. This decline resulted in reduced water retention capacity and porosity of the soil, leading to poor moisture retention and increased evaporation compared to unaffected soil. Moreover, the organic matter content in the soil was significantly depleted, inhibiting plant growth. Additionally, there was a notable proliferation of methane-producing bacteria, which contribute to the greenhouse effect. It was further observed that fire-damaged soils exhibit limited natural recovery, even over prolonged periods. .An investigation into the underlying causes of these problems revealed that actinomycetes, the primary microorganisms responsible for producing watersoluble aromatic compounds in soil, are particularly sensitive to heat compared to other bacterial species. Research demonstrated that the population and diversity of actinomycetes are significantly diminished in soils exposed to wildfires. To mitigate these issues, water-soluble aromatic compounds produced by actinomycetes were extracted and introduced into wildfire-affected soil. This intervention promoted the restoration of actinomycetes populations, enabling their normal growth in the affected soil. Consequently, various wildfire-induced soil problems were effectively resolved. These outcomes were confirmed through the study...Key Words: Actinomycetes, anaerobic and aerobic soil bacteria, methane-producing bacteria, wildfires, water-soluble aromatic compounds.

Current research shows Northern Guam to be composed of porous limestone bedrock which allow groundwater to flow out. One large discharge point has already been identified last year in north-western Guam at Ayuyu Cave. However, little is known about Tumon Bay which is known to comprise karst watersheds which should allow for SGD. This project has examined invisible groundwater discharge using a salinity meter and was able to detect two areas of concentrated freshwater discharges in Tumon Bay, with a few minor ones scattered throughout the bay. These seeps were found to have consistently lower salinity while pH varied, and hosted more marine life than other high salinity areas. Further unique coral growth in Tumon Bay’s inner lagoon was associated with these two freshwater discharges with the pH levels further segregating the types of coral species found during on-site observation. Two coral communities, staghorn Acropora and massive Porites, were found adjacent to the surveyed groundwater seeps. It’s inferred that lower wave energy in eastern Tumon Bay allows for greater plankton and other microbial growth leading to more heterotrophic coral growth, favoring Porites corals, while Western Tumon Bay has higher wave energy which leads to the growth of more autotrophic corals, such as the Acropora found in the first area surveyed. This is the first study to document the presence, location, and consequences of invisible freshwater discharges across the billion-dollar bay. This study gauges the effects of SGD on inner shore habitats, also providing a coral cover assessment across Tumon Bay using transects and quadrats. These discoveries allow for strategic coral planting, designated areas needing government protection, and show areas of appealing inner lagoon coral growth for tourism.

本研究以具空間梯度的臺灣周邊離島測站實測數據及衛星氣膠光學深度時空變化及相關性推斷東亞境外氣膠對臺灣北端PM 2.5濃度的影響。我們選取鄰近中國的金門與馬祖、中等距離的馬公及臺灣北部(富貴角、基隆)、遠離大陸的日本離島(石垣、那霸)共七站，分析2015-2021年東北季風盛行冬春季與西南季風盛行夏季的資料。結果顯示各測站冬春季PM 2.5濃度均較夏季高2-3倍並由西向東下降，冬春季相關性均較夏季高；針對高濃度事件，氣膠光學深度顯現冬春季高PM 2.5傳輸和各站測值在時空上緊密連結，由西向東下降；冬春季當地汙染極低的馬公平均濃度與臺灣北端兩站數值一致但夏季顯著較低，顯示季節性境外汙染對馬公和富貴角、基隆影響程度的一致及重要性。以上結果均支持東亞境外氣膠傳輸為臺灣北端冬春季PM 2.5主要來源。

Due to widespread water shortages, there is an increasing need for innovative water conservation strategies, such as reusing greywater from laundry. The World Health Organization (WHO) recognizes greywater as suitable for plant irrigation, but commercial laundry detergents contain synthetic chemicals that can harm both the environment and plant health. Soap nuts, derived from the Sapindus mukorossi tree, offer a natural alternative. Their pericarp is rich in triterpenoid saponins, amphiphilic compounds, composed of hydrophilic sugar group and hydrophobic triterpenoid sapogenins. These saponins mimic the chemical structure of surfactants in detergents, allowing soap nuts to act as natural foaming and surface-active agents in water. As a result, soap nuts have long been used as a sustainable option for shampoo and laundry detergent in many Asian countries (Sochacki & Vogt, 2022). Greywater, an often overlooked resource, is generated from household activities like laundry, showers, and basins. Unlike blackwater, it contains lower levels of pathogens and bacteria. However, due to a lack of awareness, greywater is frequently mixed with blackwater and directed to the same sewage treatment systems (Greywater Systems: From Recycling to Filtration, n.d.). Greywater accounts for 50-80% of a household’s daily wastewater (Wong, 2011). Repurposing greywater offers a promising and sustainable solution to address water conservation challenges.
