在本次實驗中,我們發現溶液中的帶電離子,會因為離子團的熱運動,和電偶極的庫倫吸引力(electric dipole)的交互作用下,使得電解質溶液的I-V curve(電流-電壓 曲線),具有類似磁滯曲線(Hysteresis curve)的效果,同時我們運用光學干涉的原理,證實此時在電場作用下,離子團會互相順著電場方向作條列鍵結,而加熱實驗也證實,熱運動會使溶液的I-V curve(電流-電壓 曲線)變的不一樣。另一方面,我們也發現,在給予電解質溶液一外加的衝擊電壓時,該溶液的電荷分布,?會因為彼此的互相擠壓以及自由擴散的作用下,而形成一震盪分布,其所顯現出來的,則是電壓的震盪變化。最後由於震盪波紋的變化,在起始時與中段之後有著明顯差異,我們對此變化提出看法和證實,相信內容是精采可期的! In this experiment, with the interaction of the heating action of ionic atmosphere and electric dipole, we find that ionic in the liquor makes the I-V curve in the electrolyte liquor show up with the effect similar to Hysteresis curve. Meanwhile, we practice the principle of interference to prove that at this moment, under the influence of electric field, ionic atmosphere will connect to each other in line following the direction of the electric field. It is also proven that in the heating experiment, heating action will make I-V curve in the liquor different.On the other hand, we also find with extra electric impact, the charge distribution of the liquor will form a oscillation, that is, the changes of the voltage oscillation under the inter-collision and the free spread. We offer our viewpoints and proofs about the obvious changes of oscillation wave in their beginning stage and after their middle stage. We believe that the marvelous content is surely worth of your expectation.

Few plants can grow in the place where Wedelia trilobata grows. In the following experiment, the leaves ans stalks(of the plants from Wedelia trilobata) are extracted for experimental purpose .The data and records of the experiment have shown that Wedelia trilo ata indeed refain the growth of plants such as mung bean, teeding seed, yeast’s respiration and the photosynthesis. We use the function of dieing the polyphenols to know that the Wedelia trilobata can produce Allelochemicals called as the polyphemols The mesophycell produce the polyphemols from chloroplast of cortex,the polyphemols transport to root and release from root exudation. The plant will absorb polyphemols of the soil, and will affect the growth of the plant. If we can separate and purify the Allelochemicals, we can make it as natural herbicideb. 南美蟛蜞菊所在之處,少有其他植物,本實驗採南美蟛蜞菊植栽區之土壤與南美蟛蜞菊莖或葉之萃取液進行相剋作用之研究,結果顯示南美蟛蜞菊確實會抑制小麥與綠豆種子萌發及幼苗生長,並抑制酵母菌的呼吸作用及植物光合作用中之光反應。 利用多酚類染色方法得知南美蟛蜞菊產生的相剋化合物為多酚類,且該多酚類由葉肉細胞與莖內皮層中具葉綠體之細胞產生,經韌皮部輸送至根,再由根經泌濾作用釋出。土壤中的多酚類會被植物吸收,進而影響植物的生長與發育。 若能將該相剋化合物---多酚類分離與純化,或可作為具選擇性之天然除草劑。

阿拉伯芥AtYAK1 基因5'UTR 中的開放讀序框(uORFs)對基因表現調控之探討
在模式植物──阿拉伯芥(Arabidopsis thaliana)中,AtYAK1(Arabidopsis thaliana Yak1-related protein kinase)是目前發現唯一屬於DYRK(Dual specificity Yak1-Related protein Kinase)的蛋白激?。雖然之前研究已證明,不同物種之DYRKs 和細胞的生長與發育過程有關。然而,其在植物中的生理功能卻尚未被明確地研究報導過。在先前的研究中,為瞭解AtYAK1 在阿拉伯芥內作用之位置,前人選取AtYAK1 基因ATG 上游約2.5 kb 的序列(Upstream Element, 2.5KUSE)建構至一含有GUS(β-glucuronidase)報告基因的質體中,並轉形至阿拉伯芥,進行GUS 組織染色分析。但在初步結果中,並沒有在轉殖株觀察到明顯的GUS 表現。進一步分析,我們發現在2.5KUSE 序列末端約0.5 kb 的5’非轉譯區(5’untranslated region, 5’UTR)中,有四組開放讀序框(Upstream Open Reading Frame, uORF)。有趣的是,許多研究也顯示,uORFs 會影響轉譯過程中的再起始(re-initiation)作用而調控該基因的表現。另一方面,前人亦透過構築好的2KUSE 轉殖株(即不含有5’UTR)進行上述GUS 實驗。結果發現,此2KUSE 轉殖株的GUS 表現非常顯著。本實驗即要瞭解AtYAK1 的uORFs 是否也會影響其蛋白質的合成。首先,我們以點突變的方式將四組uORFs 中之ATG 換成TTG,目的為構築不含有uORFs 之5’UTR(mutated uORFs, ΔuORFs)。在進行原生質體短暫表現分析法(protoplast transient assay)及GUS 組織染色分析後,將結果與含有uORFs 的結果作比較:當缺乏uORFs 後,其3’端報告基因的表現量確實比原來顯著。綜合以上,我們認為此uORFs 對於AtYAK1 蛋白質之表現佔有相當重要的影響地位。最後,我們對5’非轉譯區是否存在開放讀序框進行阿拉伯芥全基因組分析,相關結果亦於本研究報告中分析討論。AtYAK1(Arabidopsis thaliana Yak1-related protein kinase)is the first DYRK(Dual specificity Yak1-Related protein Kinase ) family member identified in the model plant ─ Arabidopsis thaliana and exists as one copy gene in Arabidopsis. Previous studies showed that many eukaryotic DYRKs are involved in regulating the growth and development of cells. However, the study of AtYAK1 in Arabidopsis is lacking to date. In order to understand where AtYAK1 expresses and functions in plants, a 2.5 kb fragment which is located upstream from the major ATG of AtYAK1(termed Upstream Element, 2.5KUSE)was previously constructed to drive the expression of a reporter gene, GUS(β-glucuronidase), in transgenic Arabidopsis. Much to our surprise, no GUS expression signal could be detected in such transgenic plants. When further analyses were performed, we found that there are four upstream open reading frames (uORFs) in the 5’untranslated region ( 5’UTR ) within the 2.5KUSE. Many studies indicating that the uORFs can regulate the translation of downstream ORF encoding the major gene product through the procedure of translation re-initiation. This action represents a mode of translational regulation for gene expression. Indeed, GUS activity could be readily detected in transgenic plants expression 2KUSE::GUS, a construct lacking the 5’UTR of AtYAK1. In this study, I have tried to elucidate whether the uORFs of AtYAK1 can regulate the translation of the downstream major ORF. First, in order to construct a 5’UTR fragment of which uORFs have been mutated(ΔuORFs), we apply site-directed mutagenesis to substitute ATG with TTG for the four uORFs and examine the expression of GUS driven by this mutated 2.5KUSE. After analyzing the results in both Arabidopsis protoplast transient assay and transgenic Arabidopsis, stronger expression of reporter genes in both systems were observed when the four uORFs were mutated. We have also confirmed that, in transient expression system, the increase of reporter gene activity was not due to the excess accumulation of the corresponding mRNAs. Rather, it is the four uORFs which play an important role in negatively regulating the translation of AtYAK1, possibly via inhibiting the translation re-initiation of major ORF. A genome-wide examination of uORFs in all Arabidopsis genes was also performed to assess the possible contribution of uORF in regulating gene expression.

本研究以b04課程中的巴斯卡三角形為研究對象,將原先巴斯卡以「1」為首、「+」為運算符號的規律三角形,改為以「-1」及「ω 」為首、「×」為運算符號,分別就其產生的新三角形作探討,發現其中似乎隱藏著原先三角形所沒有的規律性。為了更瞭解這種規律,藉由電腦軟體繪出其圖形,圖形顯示出如碎形般的複製關係,不論放大或縮小,其中的遞迴關係並未改變,頗令人好奇,因此著手研究。研究過程中對於圖形的規律性採用先臆測、接著歸納、最後給予證明的方式呈現。得到以下的結論:一、分別以數列呈現新三角形圖形的規律性。二、分別將新三角形中每一列中的某數字(如-1、ω 或ω 2 )的個數予以通式表之。三、分別推算出新三角形第n 列第j 行的數是「1」或「?1」及「1」或「ω 」或「ω 2 」。四、相同的模式,在特定的圖形範圍中,不斷重複出現。許多研究將巴斯卡三角形中的所有數,以某數為模的餘數紀錄下,去探討其餘數在新產生的巴斯卡三角形中的分布情形;而在碎形的研究中,大部份著重如何畫出碎形。本研究著重圖形其規律性的探討,提供上述研究不同角度的詮釋與探討。 This research subject is based on Pascal’ s triangle in senior high school curriculum. The regular triangle begins with「1」and use「+」as operation. Let 「1」 be replaced with「-1」and「ω 」, the operation sign「+」be changed into「×」. I do research on the new triangle and discover the seemingly hidden regularity which doesn’t exist in the original one. To understand more about this regularity, I draw figures through the computer. The figures show the relationship of reproduction as fractal. Whether the figure is enlarged or minimized, it’s surprising curious the recursive relationship doesn’t change, so we begin to work on research. In the process of the research, we make careful observations, assumptions and deductions about the regularity of the figure. Finally, we come to some conclusions by means of giving proofs:(1)Present the regularity of the new triangle figure with progression.(2) Present such numbers as「-1」, 「ω 」, 「ω 2 」 in each row of the new triangle with formulas separately. (3)Figure out the number in the row n and in the column j of the new triangle is「1」or「-1」,and「1」or「ω 」or「ω 2 」. (4)The same model appears again and again in the specific range of figure. Many researches record Pascal’s triangle modulo certain number to explore the distribution of remainders in the new triangle. In the research of fractal, how to draw fractal is mostly focused on. The exploration of this research emphasizes the regularity of figure, offering the interpretation and exploration of researches above from different angles.

首先我們考慮無孤立點的無交錯分割按區塊的細分。我們得出:集合{1,2,...,n}恰含k個區塊的無孤立點的無交錯分割的個數為:
其次,我們證明bn,k和多邊形的剖分有令人訝異的關連。令dn,k是用不相交對角線將凸n 邊形分成k 塊的方法。我們用代數方法證出 bn,k = dn+2−k ,k,也給了一個新的組合證明。
最後,透過對應的方法,我們找出了七個嶄新的組合結構,這些結構都是以Riordan 數來計數。
Partition the set {1,2,...,n} into several nonempty sets (blocks) and call it a partition. If there exists 1 ≦ a It is known that the nonsingleton noncrossing partitions are counted by Riordan numbers {rn}n≥0 =1,0,1,1,3,6,15,36,... In this paper we study the properties of them.
First we consider the enumeration of nonsingleton noncrossing partitions in respect to the blocks. We prove that the number of nonsingleton noncrossing partitions of {1,2,...,n} with k blocks is
Then we give a connection between nonsingleton noncrossing partitions and polygon dissections. Let dn,k be the ways to dissect an n –gon with noncrossing diagonals. We prove that bn,k = dn+2−k ,k
We also give a combinatorial proof. Furthermore, by way of the technic of bijection, we find 7 new combinatorial structures counted by Riordan numbers.

日光燈是我們最常用的照明設備。傳統的日光燈是屬於電感性的負載,接上電源後其電壓與電流的波形會產生異相位的問題,造成無效功率。本研究是以簡單而且經濟的方法在日光燈的兩端並聯電容器以改善其電流落後電壓的情形,減少無效功率,降低電力的消耗。研究中測量日光燈的等效阻抗,並加以相應的補償電容,從電路實驗中觀察,得到功率修正的結果。Fluorescent lamps shine our lives everywhere. However, traditional fluorescent lamps are inductive loads and produce a phase angle between voltage and current when connected to an alternating power supply, which leads to considerable electricity losses. This project uses parallel capacitors with the fluorescent lamp to compensate the phase difference between current and voltage, and thus reduces power consumption. In the study the impedance of a CFL (Compact Fluorescent Lamp) bulb has been measured and compensated with corresponding capacitance. Finally, the power consumption reduction is verified with experimental results.

以阻抗匹配調整太陽能最大功率輸出之研究
In recent years, the price of the oil keeps rising continuously. As a result, the prices of the commodities are rising, too. But what does this mean? This situation stands for the resources on are becoming more and more valuable. A few months ago, I read a Weekly Business Magazine and a Scientist Magazine. They both pointed out that the resources such as oil would disappear after fifty years, and that was a horrible phenomenon. Since almost everything in our modern lives are related to oil, like automobile, motorcycle and air plane. They all need oil for its ingredient. Even plastic bag plays a part in the products of it. I really cannot imagine what it would be like if we don’t have oil after fifty years. Owing to the green house effect is becoming more severe, there are many substitution resources found, such as hydraulic power, wind power and solar energy…etc. What we’re discussing in our topic is how to enhance the power of solar energy, because for now, we all know that the solar module is very expensive and it cost a great deal of money just only one square meter, but the price of module converted from sunlight or heat energy can’t be higher. Therefore, the work is mainly to design and carry out a solar max power point track. 近年來,油價不斷的上漲,連帶著民生的物價漲幅也是越來越可觀,但…這意味著什麼 呢??這所代表的是地球上的資源可以說是越來越珍貴了,前陣子曾經看過商業週刊、科學人 雜誌…他們紛紛所指石油這種能源可能在五十年後就消失殆盡,這個可是非常可怕的結果。 鑑於溫室效應愈趨嚴重,許多的替代能源紛紛出籠,像是風力、水力和太陽能等等。我們這 次的主題是在討論如何提高太陽能效率,現在的太陽能模組我們都曉得非常的昂貴,但是由 太陽轉化成電能的效率卻是低的可以。所以本作品主要目的在於設計與實現一個太陽能最大 功率追蹤器。

口蹄疫病毒鞘蛋白rVP1 誘發Prohibitin 之遷移
細胞凋亡具有控制生物體細胞數目之功能,能讓特定的細胞走向死亡,因此若能掌握其作用機制,便可能藉由調控細胞凋亡的發生,進而應用於癌症治療。前人研究(2.)指出,經基因重組技術純化之口蹄疫病毒鞘蛋白rVP1,會導致BHK-21的Akt 蛋白質去活化,引起細胞凋亡的現象。然而在其後續的研究中,卻發現到在BHK-21中大量表現磷酸化的Akt 蛋白質,並無法反轉由rVP1 所誘發之細胞凋亡。因此本實驗利用二維蛋白質電泳,尋找Akt pathway 以外之細胞凋亡相關蛋白質。目前已證明Prohibitin 此一蛋白質,在由rVP1 所引起之細胞凋亡中,有自細胞核移動至細胞質的現象。此外,亦經由實驗排除Prohibitin 位於Akt pathway 的可能性。Western Blot 之結果更顯示,經rVP1 處理後,Prohibitin 在很短的時間內便出現遷移的現象,故推測其具有調控細胞凋亡上游反應的功能。Apoptosis can lead some specific cells to programmed death, thus, it is a major way for creatures to control their cells amounts. If we can command the mechanism of apoptosis, we may use it as a therapy for cancer by artificial regulation of apoptosis. VP1 is one of the capsid proteins of Foot and Mouth Disease Virus (FMDV). A research (2.) has indicated that the recombinant VP1 (rVP1) can result in dephosphorylation of Akt in BHK-21, and then lead the cells to apoptosis. However, in their follow-up experiments, they discovered that even if they expressed great amount of phospho-Akt in BHK-21, it still couldn’t reverse the apoptosis induced by rVP1. Therefore, this experiment takes the advantage of two-dimension protein electrophoresis (2D) in order to find apoptotic proteins excluded from the Akt pathway. I have found that Prohibitin exports from nucleus to cytosol after rVP1 treatment. Furthermore, I eliminate the possibility that Prohibitin’s may be located in Akt pathway. The results of Western Blot also shows that protein amount of Prohibitin in BHK-21 increase after rVP1 treatment, hence the purpose of nuclear export of Prohibitin might not be to degrade it. It might have some much more important function in the process of exportation. Besides, Prohibitin exports to cytosol in quite a short time after rVP1 treatment. According to this phenomenon, I suppose that Prohibitin has a role as a regulator of apoptotic up-stream reactions.

「渦」藏「聖」機--以渦流脫離重新詮釋聖嬰發生的原因
If we place a block in continuous, steadily flowing water, some periodic eddy currents will appear behind it. In my report, I would like to introduce a new way to explain how the periodical movement of eddy currents would help to triggering El Nino. According to my experiment, these eddy currents have a certain life cycle, and the eddy current give a force, which drag water form the area they just went by. It will cause water level became lowest for a period of time. These phenomena are also shown in the real data of “Sea Surface Height Anomaly”, it is a quiescence period, and then changes into the highest one it is interesting that highest one always follows by the starting of El Nino. Another important result from my experiment is that, in the same fluid, the frequency of eddy currents is controlled by 2 variables: Size of the block and velocity of the flow, From this result, then get the frequency of eddy current-occur every 3.2 years. It is just correspond with frequency of historical data the El Nino from the 70’s to the present.
本報告嘗試以南極繞極環流在南美洲南端產生週期性渦流脫離的現象來解釋聖嬰的發生根據水槽實驗的結果,水流在通過障礙物後渦流脫離瞬間,會形成一水位低的空區,之後在周圍的水大量湧入,水位突然升高,並有一段時間的振盪。另外,實驗結果也顯示,渦流形成和脫離頻率大致上和注水流速成正比,且和障礙物的大小成反比。根據此結果,對照實驗結果,我認為1993 年3-4 月,1996 年1-6 月及2001 年7-10 月三個「海平面高度異常」的最低值密集帶,此極可能是渦流脫離的時段。且對照「海平面高度異常」實際資料後,發現「海平面高度異常」的「最低值密集帶」後均伴隨水面「寧靜期」,接著就出現周圍暖水流大量湧入的「最高值密集帶」,此時南美洲東南側海水溫度驟增,接著馬上接續著聖嬰的到來。「海平面高度異常」分析的結果,指示渦流脫離的「最低值密集帶」和顯示著聖嬰到來的「最高密值密集帶」間約間隔半年左右。我們推算水的史托爾數約為1,以這個值代入實際南極繞極環流通過南美洲南端,得到渦流脫離的頻率約每3.2 年一次,和長期聖嬰發生的平均頻率非常接近。
