在這份報告中，藉由高速攝影機，我們可以更清楚地觀察到液滴在撞擊固體表面瞬間的形變現象。分析以不同的液滴、不同的撞擊表面、不同的瞬間撞擊速率以及不同溫度的金屬表面，並探討在不同的條件下，韋伯常數(Weber Number)與水滴散開之間的關聯。實驗結果顯示，當表面張力與密度比值大，或當液滴速度快時，液滴形變越明顯，但其形變量有一最大值，而其薄水層傳播速度會隨時間增加而減少，但其環狀波在彈回時幾乎是呈等速度的彈回。若是液體表面張力較撞擊面附著力大者，或撞擊面溫度超過攝氏400度時，在其薄水層達到最大直徑時，便會向內收縮，形成一顆水珠。

超音波應用於臨床已行之有年，而以穿透式超音波打入腦部的想法也已提出，本實驗目的即為測試低強度間歇性超音波達到腦部受傷後治療的可能。本實驗採用星狀細胞培養模式來探討，首先以腫瘤壞死因子α(Tumor Necrosis Factor-α, TNF-α)模擬中風缺氧的狀態，並利用低強度間歇性超音波刺激星狀細胞，然後檢測其培養液中一氧化氮(nitric oxide, NO)的濃度變化，以及大腦衍生神經營養因子(Brain-derived Neurotrophic Factor, BDNF)、神經膠質衍生神經營養因子(Glial-derived Neurotrophic Factor, GDNF)之mRNA 表現的情形。由實驗結果顯示，在TNF-α存在狀況下則能使NO 濃度上升，施打低強度間歇性超音波可促使NO 增加，並提升上述BDNF、GDNF 兩種蛋白質之mRNA 表現，BDNF 可幫助支持神經元生存，促使新神經元和突觸的發展及分化；GDNF 可有效提昇許多類型神經元生存率；而適當之NO 濃度可以調節神經傳遞物質釋放和腦血流，乃至於影響到記憶的產生。我們初步的結果也顯示在TNF-α存在下，超音波可以增加BDNF 及GDNF 蛋白之產生，因此本研究成果顯示低強度間歇性超音波可提供有利於神經元的環境。The ultrasound technology has been widely applied in the clinical practice for many years, such as monitoring of fetus, lithotripsy, rehabilitation after fracture, as well as the ultrasound stimulation of brain tissue, etc. The purpose of this study is to investigate the therapeutic effect of low intensity pulsed ultrasound (LIPUS) on the injured brain. In this study, we adopted the in vitro model of astrocyte cultures. The tumor necrosis factor- α (TNF-α) was used to simulate the condition of ischemic stroke. We used LIPUS to stimulate the cultured astrocytes, then we ssessed the concentration of nitric oride (NO) in the culture medium. We also assessed the expression of messenger RNA (mRNA) of both brain-derived neurotrophic factor (BDNF) and glial cell-derived neurotrophic factor (GDNF). The results showed that NO increased after the addition of TNF- α. In addition, treatment of LIPUS increased the expression of NO, as well as the mRNA of both BDNF and GDNF. The BDNF is able to support the survival of neuron, as well as stimulate differentiation of neurons and synapses. GDNF can also increase the survival of various kinds of neurons. Furthermore, NO may regulate the secretion of neurotransmitters, increase the blood flow in the brain, as well as enhance the processing of memory. Our preliminary results also demonstrated that both BDNF and GDNF protein increased in response to LIPUS in the presence of TNF-α. Therefore, treatment with LIPUS implicated an environment favoring the protection of neurons.

We inferred the original Feynman triangle theorem from equilateral triangle into common triangle and from same ratios of dividing points into different ones. The conclusions are below： 由原始費曼三角形原理中的正三角形等比例分點問題，推廣至一般三角形的分點等比例及不相同之比例，得到如下之結論：

南投溪頭米堤飯店在2001 年因土石流受創，產險公司以「土石流即是山崩」為由拒絕理賠。歷經5 年的訴訟後，2007 年1 月台灣高等法院認定，土石流屬保險契約中所規範的「洪水」，並非「山崩」，判決產險公司應給付賠償金。土石流究竟是洪水？是山崩？主要因素便是土石流發生的水文因子。本文藉由博愛村的現場調查及文獻探討先作初步資料分析（preliminary analysis），了解到地文因子(physiographical factor)是土石流發生的充分條件，非必要條件；一般僅考慮雨量因子，把地文因子看作常數（忽略地文因子受水文因子歷程(course)影響），簡單易懂，但在安全與經濟考量上有待討論。使用類神經網路對已發生過的土石流事件計算土石流發生臨界曲線，並使用模糊理論計算松鶴地區其受水文因子影響的土石流發生臨界曲線，這樣的模式，考慮似乎比較周到。由「米堤飯店」的例證，更說明土石流發生的水文因子的必要性。Lemidi hotel, Xitou, Nantou because mudflows and landslides and was wounded in 2001. The Insurance Company refused to settle a claim on the position on “A landside is a debris flow”. After the lawsuit which was going through 5 years. In January, 2007, the High Court of Taiwan asserted that the adversity in the 2001 belongs to “the flood” in the norm of the insurance agreement. As the norm of the insurance agreement said, the debris flows in the land is the flood, not the “landslide”. The High Court of Taiwan judged that the Insurance Company should compensate the Lemidi Hotel. Is debris low a landslide or a flood? The main cause is the Hydrology in the happening of a debris flow. We did preliminary analysis of forms by on-the-spot investigation on Song-Ho Village and reference discussing. We realized that physiographical factor is an abundant condition for a happening of a debris flow, not the essential condition. Generally, people only consider rainfall factor. And they consider physiographical factor as not as constant (neglect the influence of hydrology factor to physiographical factor). We can understand easily in that way. Therefore, in the aspect of security and economy, there is much doubt that is needed to be discussed. People who use neural network method to calculate the curve of the debris flow happening , and used fuzzy theory to calculate the curve of the debris flow happening which is influenced by the hydrology in Song-Ho Village. In that way, we may consider more thoughtful. From the example of the Lemidi Hotel in Nantou, we can prove that how necessary the hydrology factor in the debris flow is.

本實驗使用磁流變流體(Magnetorheological fluid, MRF)來估查其磁場作用下的光學性質。本實驗採用Lord公司的MRF-132LD磁流變流體加以稀釋到不同的重量濃度，並以氫氟酸蝕刻玻片產生不同的厚度。吾人觀察到濃度參數以及厚度參數均對MRF薄膜的光繞射產生影響。膜厚越薄，產生的繞射較明顯，而重量濃度較小的容易亦有較大的繞射角度。吾人亦移動上下兩玻片相對位置，施加剪力的作用，繞射現象也產生明顯的改變。\r The Magnetorheological fluid (MRF) is used to observe the optical properties under the vertical magnetic field , The MRF-132LD from Lord Company is used, The MRF is diluted to different weight ratio of particulate and carrier fluid . The different thicknesses of the MR thin film are also made with the diluted MRF. The concentration of the MRF and the thickness of the thin film are both found to have significant effects on the optical diffraction phenomenon. The optical diffraction is also found to be affected by the applied shear force to the thin film.

在本研究中，我模仿蟑螂的行走方式，來製作可以在各種地形以不減速的方式前進的機器車。在偶然機會下，我觀察到，蟑螂可以順利爬越米堆，因此對蟑螂的運動方式感到興趣。我用微型網路攝影機拍攝及觀察蟑螂的行走方式。發現蟑螂在快速行走時，是以三隻腳為一組，六腳兩組交互進行前進的動作。由於三點構成一平面，使蟑螂在快速移動時，相當的平穩。我將此原理融入蟑螂車的設計，並根據這個原理，利用舊玩具四驅車改裝成「六驅車」，成功的製作出模仿六足昆蟲行走方式且可以在各種地形順利前進的機器車。為了更客觀的比較，我應用樂高積木的馬達組合，製作了一部純轉動前進的六輪傳動車，及另一部轉動兼走動的六輪蟑螂車。並利用微電腦控制兩種車維持相同的驅動速度前進(93.33 rpm)，於各種路面實地測試，證實蟑螂車越野的性能的確強很多。未來若可以將六足昆蟲行走方式的概念應用到汽車製造，車輛的越野性能必然大幅提昇。\r \r In this research, I developed a six-wheel driving vehicle simulating the movement of cockroach. The resultant motion machine can un-intermittedly run on terrains without speeding down. Occasionally, I observed that the cockroaches can crossover a heap of rice. Therefore, I was very interested in and eager to learn how cockroach runs. I recorded the movements of cockroaches by using mini web camera and analyzed the moving characteristics of cockroaches. It was discovered that the cockroach marches quickly by interchanging two groups of foot in which each group consists of three feet. As a table can be supported by three legs, the cockroach runs steadily and rapidly. I have designed a motocross vehicle based on the mechanism of the way that cockroach runs. A six-wheel driving car is constructed by modifying four-wheel driving toy cars. By simulating the motion complex of six-foot insects, the six-wheel driving car turns out to be an all-terrain vehicle. To be more objective in comparison, I built two types of six-wheel driving cars by utilizing the LEGO TECHNIC motor building set: one with regular and synchronous rotation, and the other one with eccentric shaft rotation emulating cockroach marching movement. I applied a microprocessor to control the motors in order to maintain the same driving speed (93.33 rpm) for both cars during the road test. The experimental results show that the proposed cockroach motocross car performs superiorly especially for the rugged terrain. In the future, the off-road capability of a jeep can be improved by introducing the concept of six-foot insect movement to vehicle design.

本研究利用一種不需藉外加幫浦，以重力驅動即可自行使液體流且形成層流的系統。因微道尺寸夠小，足以形成層流，再由中入口、出口儲液槽的高度差、毛細現象以及表面張力，驅動流道中的液體、形成流速穩定的層流。由層流的性質得知，死菌只能隨流層前進，而因活菌有運動能力，能自分布於系統中，如此便可將死亡及活力較差的大腸桿菌從中分離，並探討各種影響細菌分離的機制。

日照影響花芽分化及生長試植物生理學上的重要課題,根據相關文獻指出,蛋白質類型的變化是影響開化的重要關鍵,大豆是短日照植物,分別以長日照(LD18hr/DAY)和短日照(SD6hr/DAY)處理,抽取葉片中的蛋白質以SDS-PAGE.2D-SDS-PAGE分析,SDS-PAGE的實驗姐果顯示出在分子量25.2 32.9 38.6 20.6 64.0 100.6 kDa處中的蛋白質SD比LD的量多,但是在分子量16.8kDa以下的蛋白質LD含有高濃度而自SD只有一點,我們使用2D-SDS-PAGE做進一步的分析,SD與LD分為三個區塊討論(SD1-3 LD1-3)有許多蛋白自LD1.LD3出現,但在SD1 SD3中未出現,可能有抑制花芽分化的作用,而在SD2中有多個高濃度蛋白出現,可能在花芽分化上扮演重角色,其中編號P1 P2的蛋白質有較明顯的變化,根據NCBI網站上的資料顯示,P1蛋白質與光敏素C有關,而P2蛋白質則沒有找到分子量等電點類似的蛋白質;The effects of photoeriod on floral initation and develoment is an imporant phyiological subject and have studed ve he past 70 years. Accrding to the reference, polypeptide partten plays an important rolein photoperiodic induction. Soybean s a SD(short day)plant. So we planted them with 6-h(short day,SD)and 18-h(long day,LD)photoperiods. Total proteins n leaves of soyban were extracted from the vegetable,SD and LD. And using SDS-PAGE and 2-D eloctrophoresis to analyze. 25.2,32.9,38.6,50.6,64.0,and 100.6kDa polypeptides in SDS-PAGE were always present in leavess at SD but only a little bands f the polypeptides appeared at LD. And many polypeptides whose molecular weight(Mw)is below 16.8 kDa had higher concentration at LD ad Reduced at SD. We found three different areas(SD1~3,LD1~3) and analyze them. Many proteins were found n LD1,LD3 and reduced in SD2,SD5. Possibly, these polypeptides found in LD1 and LD3 play an important role in restraining floral iniiation in soybean. Many proeins had more concentration in SD2. Probably, they play an important role in photoperiodic induction and floral initiation. We found a protein labeled P1 in SD2 and it is with molecular weight(Mw) of 36kDa at isoelectric point(pI) of5.2, and it may be related to cytochromeC. We also found protein labeled P2 in SD2 and it is with molecular weight(Mw) of 40.2kDa at isoelectric point(pI)of 5.4, and we couldn't find any protein that has the similary Mw and pI in potein database about flowering and daylength.

In this study, we try to know how ectopic eye genes: eyeless(ey), eye gone(eyg), twin of eyeless(toy), twin of eye gone(toe) act cooperatively, and look for some unknown genes which affect the function of eyg. First, through human trans gene screening, we find two human genes change the phenotype of ey>eyg into dorsal out-growth when they co-express with eyg (ey>eyg+X). It means the two genes may relate to cell proliferation. Second, by sequencing the insert genes of mutant fly which was found by EP screening, the result shows the site of the insertion is the same as effete (eff) gene. eff translated wrong proteins which differ from functional ubiquitin-conjugating enzyme may be the major cause of the mutant eye . 本研究係探討果蠅複眼異位基因eyeless(ey)、eye gone(eyg)、twin of eyeless(toy)、 twin of eye gone(toe)間的協同作用，並尋找與eyg 有交互作用的基因、突變株。藉由人類基因轉殖篩選，找到兩株人類基因轉殖株，當其與eyg 共同表現時(ey>eyg+X)，會改變ey>eyg 的複眼性狀，造成dorsal out-growth，顯示這兩個基因可能與細胞增生有關，此外，藉由EP screening 複眼發生突變的果蠅之UAS 下游基因經比對後，位置與effete（eff）部分契合，推測複眼發生突變的原因是eff 的功能發生異常，致使細胞內蛋白質代謝失常所致。

中文摘要 本實驗先尋求將廢棄保麗龍磺酸化為陽離子交換樹脂(本實驗稱”保麗龍膠”)的方法。將保 麗龍依：丙酮溶解→硬化→打碎→與濃硫酸共煮三小時→浸於50%硫酸溶液中→沖洗→以水 浸泡的流程，即可達再造的目的；我們測得其磺酸化比例為62.5%。再利用「碘滴定法」(浸 泡式)與「相對電壓檢測法」(流動式)，依次尋求保麗龍膠吸附金屬離子的最佳條件。其中「碘 滴定法」可有效測出銅離子濃度，但手續繁瑣；「相對電壓檢測法」最大的好處是知道保麗龍 膠何時吸附達飽和必須再生。 目前我們所知，要保麗龍膠達到吸附陽離子的最佳效能，其條件依次為：使用細粒的保 麗龍膠；低濃度的金屬離子溶液；質量愈大的保麗龍膠；低溫下較慢的金屬廢水流速及pH 值約為4.30 的銅離子廢水；鈉型的保麗龍膠吸附效能優於氫型。保麗龍膠對不同金屬離子亦 有吸附力，單位體積所含離子數愈少，初始的相對電壓會愈高；在相同莫耳濃度下，不同離 子的吸附力依次為Cr3＋＞Fe3＋＞Ni2＋＞Cu2＋＞Co2＋；分次吸附確可將金屬離子完全去除；由 吸附等溫線觀察得知，可能保麗龍膠為多孔物質，導致500ppm 以下的吸附模式無法明確判 斷，1000ppm 以上則為物理吸附模式；保麗龍膠可以再生也可被覆在砂粒上達到不錯的吸附 效能；最後，我們將吸附過金屬離子的保麗龍廢膠與硫酸鈣、紙漿及些許的石灰(質量依序為 13 克、13 克、7 克、0.04 克)混合，可製成類似紙黏土，做成造型磁鐵，廢物利用十分有趣。 Abstract The Experiment will, first of all, explore the ways to sulfonate expandable polystyrene into cation ion exchange resin (called “polystyrene rubber” hereafter in the experiment). The procedures of treating expandable polystyrene are as follows: acetone dissolve→hardening→smashing→ boiling with sulfuric acid for three hours→immersing in 50% sulfuric acid solution→washing→ immersing in water so that we may reach the goal of reconstruction. We calculate the sulfonated rate to be 62.5%. Then we make use of “Iodine Titration”(immersion method) and “Opposite Voltage”(floating method) to seek for the best conditions of adsorption the metallic ion through polystyrene rubber. The former can effectively calculate the concentration of copper ion, but the procedures are quite complex. The greatest advantage of the “Opposite Voltage” method is that we may know when the adsorption of polystyrene rubber is saturated and should be regenerated. As far as we know at present, the conditions of obtaining the best effect that polystyrene may adsorb the cation ion are as follows: fine particles of polystyrene rubber; low concentration metallic solution; polystyrene rubber of which the mass is greater; at lower temperature, slower waste water flow speed and the copper ion waste water with pH 4.30; the adsorption effect of sodium type polystyrene rubber is better than the hydrogen type. Polystyrene rubber also has adsorption effect toward different metallic ion. The less ion per cubic contains, the higher the original opposite voltage. With the same mole concentration, different ion adsorption effects may range as follows: Cr3＋＞Fe3＋＞Ni2＋＞Cu2＋＞Co2＋. The batch adsorption definitely may erase metallic ion completely. By observing the adsorption isotherm, possibly because the polystyrene rubber is a multi-apertured matter, we find that it is impossible to judge exactly the adsorption model of those metallic ion solutions of which the concentrations are below 500ppm. Those which are over 1,000ppm belong to physical adsorption models. Polystyrene may be regenerated and get an adsorption effect by coating sand particals. In the last analysis, we may make paper clay and magnets of different styles by mixing the adsorbed metallic ion polystyrene rubber with calcium sulfate, paper pulp and a little lime(the mass are respectively 13g, 13g, 7g, and 0.04g). The reuse of waste is really very interesting.
