Pineapple leaf fiber (PALF) which is rich in cellulose, abundantly available, relatively inexpensive, low density, nonabrasive nature, high filling level possible, low energy consumption, high specific properties, biodegradability and has the potential for polymer reinforcement. The utilization of pineapple leaf fiber (PALF) as reinforcements in thermoplastic form for developing low cost and lightweight composites Pineapple leaf fibre (PALF) is one of them that have also good potential as reinforcement in thermoplastic composite. The objective our research is to characterize PALF and to investigate the effect of fibre treatment on the mechanical properties of PALF reinforced polypropylene (PP) composite PALF was obtained from pineapple plantation after the harvesting. The we dry the PALF to remove the water. Next step is grind the PALF into small particle. Both PP and PALF were compounded using internal mixer machine prior to compression moulding via hot press machine to form a sheet. After forming the composite sheet, samples were prepared for tensile test (ASTM D638), flexural test (ASTM D790) and impact test (ASTM D256).

世界上有許多病患，需要在體內植入電子醫療裝置，才能維持生命。然而，電池充電的問題卻一直無法克服，於是必須透過開刀重新更換電池，如此不僅增加病患的痛苦，也增加了醫療成本與環保問題。然而，過去研究以提高電池蓄電量為主，只有極少數研究著重在探討隔空充電技術，例如:動物體內電池充電。本研究主要是應用電磁感應原理，設計一套可以針對實驗兔體內體溫發射器的電池進行充電的方法，及探討充電過程所產生的電磁輻射及其影響。我們的初步研究成果顯示: (一)將24V與18V兩種電壓分別輸入電磁棒，在實驗兔動物身體表面進行充電，發現可產生的最高充電電壓值分別為4.75 V與3.64V。(二)充電30分鐘後可讓體溫發射器每二秒發射一次訊號，為期長達8天。(三) 將24V與18V兩種電壓分別輸入電磁棒，在距離電磁棒5-60cm的範圍，最大的電磁輻射值為179.6mG及0.1 mG。本研究證實我們設計的電磁棒可以對兔子體內電池進行隔空充電，並且不會對實驗兔子造成電磁輻射傷害。我們建議未來可以應用此方法解決動物體內醫療電子元件的充電問題。

本研究目的1.探討催化劑對光子晶體SiO? 合成的影響，依據催化劑對光子晶體製作的數據，統整歸納出不同濃度的氨水催化劑對於SiO? 的吸收光譜與粒徑大小等性質的影響。2.尋找簡易的方式進行光通道的製作。 採用溶膠凝膠法將tetraethylorthosilicate(TEOS) 以氨水做催化劑在乙醇溶液中的水解及縮合反應製作單分散SiO?粉體。 嘗試將細線附著在玻片上進行排列，排列完成後將細線拉起企圖製造一條溝道。 實驗結果,催化劑會影響合成SiO? 的顆粒大小，隨著催化劑濃度增加，顆粒大小也隨之增加。使用細線可成功製造出凹陷的孔道，但目前採用之線仍嫌太粗，欲尋找奈米線材加以取代以製造出更適用之光通道。 ;The purpose of this research is 1.to find out the influence of the catalyst on compounding silica photonic crystals . According to datum , I can generalize the connection between the consistency of catalyst and the particle size of photonic crystal. 2.to find easier method of making the passage of light. I used tetraethylorthosilicate (TEOS) as a reactant and ammonia as the catalyst to react hydrolysis ,water condensation and alcohol condensation in ethanol. I tried to put fine lines on sheet glasses. After the arrangement of the silica particles, I took apart the lines attempting to make sunken ditches. The outcome of this ecperiment show that partical size increases with the consistency of catalyst. We can use fine lines to make the sunken ditches, but the line is not fine enough that I should find much finer lines to make it.

磁鐵與非磁性金屬轉盤因冷次定律產生阻尼效應而產生煞車效果，常常在物理實驗提到。但如何設計一個渦電流煞車器，又好像不是一件簡單的事。因為牽涉到許多變因，如轉盤材質、厚度、磁鐵與轉盤中心距、磁鐵數量、磁鐵與金屬轉盤距離、磁鐵移動速率等。本研究以”實驗驗證法”的方式，企圖為這些變因找到可依循的準則，進而充分掌握設計要點。為了有效率地分析這些變因，我們自行製作了一套「渦電流煞車分析系統」，可減少許多實驗時間並可記錄即時數據。另外，我們也量測渦電流在煞車系統的熱能分怖情形。在分析這些變因後，提出一份實用的設計指南。在最後，藉由控制磁盤的移動速度及與轉盤的距離，來分析渦電流煞車的各種即時「煞車曲線」。

本研究設計了兩個風洞實驗裝置，分為水平風洞與垂直風洞，兩者皆進行飄浮模擬試驗進而推算微小物質的運動量，並以小保麗龍球作為標準圓球，確保儀器的可用性，最後再透過醫檢儀器進行驗證。水平風洞利用機率的觀念統計孢子的分布，透過孢粉落下的高度差，帶入公式求得質量。垂直風洞則使用高倍率攝影鏡頭觀察孢子飛行，利用三力平衡的觀念推算其微小質量。最後，無論是自製風洞測出的質量、精確度、成本、測量速度和加速度的能力以及花費時間的長久，本實驗的儀器皆有優勢。 

在這能源短缺的時代，開發替代能源已經成為主要課題。利用光觸媒特性所製成的色素增感型太陽能電池，因二氧化鈦光觸媒受到紫外光照射才產生電子躍遷，吸收光的頻率區域狹小，實用性不高。因此研究氧化鋅、二氧化錫與二氧化鈦混合，是否能提升該電池的轉換效率。藉由各種變因的探討，從中選取最有利的方式，使太陽能電池發揮更大的效益。除了以溫度、電解質、混合比例等因素外，增加電極面積以及串聯均可提高電壓與電流，以增加日常生活的實用性。如不斷的改進發展，諸如電解水、使小燈泡發光，甚至各種小家電用品的使用，都可應用於其中。In times of energy shortage, exploring the alternative energy has already become a main issue. The dye solar photocell is using photocatalyst characteristic. Because the electron transition is caused by lighting up the titanium dioxide photocatalyst by the ultraviolet, the frequency of spectrum is narrow and small. It is thus impractical. Therefore, we research whether or not the mixtures of zinc oxidize and tin oxide with titanium dioxide can improve the conversion efficiency of the dye solar photocell. Through discussion on various kinds of factors, we can choose the best way to make the dye solar cell yield more efficiency. In addition to the factors such as temperature, electrolyte, mixed proportion, etc., increasing the area of electrodes and contact can improve the voltage and electric current. That way we can increase the practicability for daily use. With constant improvement, it can be applied to many kinds of things, such as electrolyzing water, small bulb lights, even small household appliances.

傳統的類神經網絡人工智慧多半是以受控訓練為主。然而在本次研究中，我們先建構出一套以類神經網絡模型為基礎的人工智慧，再利用社群網站噗浪（Plurk）上使用者與此系統的互動，訓練類神經網絡，以期驗證社群網站作為訓練來源的效率與準確度。我們利用分析詞、句的方式，促使系統做出自動的回應，同時並收集相關資料作為統計與修正之用。經過漸進式的調整與精進後，我們成功利用高度模組化的人工智慧系統，達成「利用社群網站資料自我修正」的目標，且其準確度呈現遞增的趨勢。我們相信只要充分掌握社群文化，社群網站做為資料來源對學術研究必有所裨益，且能為自然語言領域帶來更多可能性。

Our goal is to make roll call systems at schools technological. While Rolling Call system is getting technological capacities some useful outcomes occur as well like; To remove the cost for class books by abolishing the class books used for roll call To eliminate mistakes with the usage of class book .(The numbers written incorrectly) To save again a large amount of waste paper( The short messages will be send to the parents instead of mailing the letters to the their adresses once a week about their students' absance.) To improve communication among school and parents ,by this way to prevent various kinds of problems arising from absenteeism. To make teachers school boards more efficently and motivated besides their affairs will get easier as well. To save time of school managers(They have no Works like saving the absenteeisms into e-school network because everything including all the absenteeism info will be carried into the system automatically) To save time of each lesson the teachers will not loose time for the roll call ,so they will be able to devote their time to their students and training. -Technological polling mechanism will contribute to education, this contribution will make all the students and teachers happy because all the teachers carry concern whether their curriculum will be finished or not through this system recording all the rests of teachers because of illnesses and some national celebrations.

本研究透過測量美洲蟑螂(Periplaneta americana)後足反射之程度與耗時等參數，探討中樞神經系統中各神經節在後足反射所扮演的角色。我們發現腦神經節對於反射作用有抑制與整合的效應，前胸神經節會增強反射，而後足的反射中樞位於中胸神經節與後胸神經節，腹部神經節則會抑制反射。本研究以電池座、釘書針與網路攝影機等簡單器材觀察、量化昆蟲足部反射運動，可推廣成國中生物中「反射」相關課程之行為觀察的探討活動。此外本研究也透過步足肌肉的肌肉電位圖(electromyography, EMG)記錄，證實了腦神經節在步足反射過程中具有調控功能。本研究的成果可應用在仿生醫療上，有助於術後復健或輔具製造的相關研究。

K562細胞是一種人類慢性骨髓性白血病細胞株，普遍用於研究幹細胞分化的先驅細胞，可以藉不同誘導劑分化成紅血球或巨核細胞。此研究聚焦於兩種臨床藥物：抗病毒藥物Ribavirin和組蛋白去乙醯化抑制劑SAHA，探討其誘導K562細胞紅血球分化機制。其中針對一個在許多分化機制扮演重要角色的染色質修飾蛋白TIFβ來研究，它可以召集其他轉錄因子在基因上形成抑制複合體。我們藉由定點突變探討TIFβ上的bromo或RBCC domain的乙醯化狀態對於TIFβ與抑制複合體的轉錄因子交互作用的影響。研究結果發現乙醯化RBCC domain大幅影響了TIFβ與轉錄因子的親和力，並且降低TIFβ三聚體的形成，可能導致抑制複合體無法形成進一步開啟了分化的通道。
