無疣蝎虎（Hemidactylus bowringii）與蝎虎（Hemidactylus freuatus）分類上屬蜥蜴目守宮科蝎虎屬，為本島住家附近常見且生態地位相近的壁虎，近年來因人為因素使原本有地理區隔的兩種壁虎在北部地區產生共域現象。本研究利用問卷來調查兩種壁虎分佈狀況，並用「體型大小」、「食物競爭能力」兩種指標，設計實驗評估種間競爭程度，來探討兩種居家壁虎種間競爭程度。問卷調查及物種採集結果顯示，在台北市各行政區確實存在共域現象，且分佈數量互有消長。體型大小比較上，蝎虎體型較無疣蝎虎稍大，但在統計上無顯著差異。食物競爭能力強弱比較上，以斷尾後尾巴增長量為指標，結果兩者大致相等，無顯著差異。綜合以上研究結果，顯示兩者共域後會出現種間競爭現象，程度大致相等，有互相消長現象。Hemidactylus bowringii and Hemidactylus freuatus are commonly seen in Taiwan, and their habitats are very near the area people live. Recently, two species have inhabited the same or overlapped geographical areas in northern Taiwan. This sympatric phenomenon resulted from the geographical isolation being broken by people. This research investigated their distributions in Taipei city by using questionnaire, and evaluated the degree of interspecific competitions by using indexes of the body size comparison and the food competition to design our experiments.According to results of questionnaire and animal sampling, two geckos did inhabit closely in some areas in Taipei city, and their population distributions were changing with time. According to the result of the body size comparison, Hemidactylus freuatus is bigger than Hemidactylus bowringii. But there is not a statistically significant difference between two species. The degree of food competition of two species was all square. In summary, it was occurred the interspecific competition between Hemidactylus bowringii and Hemidactylus freuatus, and the degree of competitions was almost equal.

Abstract (一)、 In our study, we discuss a m×n chess and any beginning square p finding a directed path of chessman from p moving to an end square in which the chessman moves to adjacent squares including only three directions which are right move, up move and diagonal left down move. A m×n chess is ruled into m columns and n rows creating the number of (m×n) squares (二)、 A chess directed path moves from any beginning square to end square in a m×n chess and every other square is visited just once. In the view of the beginning squares, the chess paths are solvable paths in a mxn chess and the corresponding squares are solutions. (三)、 First, we find out that some beginning squares are located in a special area with no any solvable directed paths. We define the special area be no-solution area. (四)、 According the 3-color theorem, we determine more than two thirds of no-solution area. (五)、 Then, we derive properties of reversibility and symmetry in solvable paths. i.e. A solvable path exist another solvable path by reversibility and symmetry respectively. (六)、 Utilizing the generalization of no-solution area which is extended from the concept of no-solution area provides judgment for the next moves effectively. The judgment is defined as effective move principle. (七)、 Furthermore, using the other theorem called rules of shift Hamiltonian path gets augment solutions. (八)、 According to the effective move principle finding a number of solvable directed paths, use the reversibility and rules of shift Hamiltonian paths to get augment solutions. Finally, utilize symmetry to find out all solvable paths in the m×n chess. (一)、研究規則：在m×n 的格子中，任取一格A 當作「起點格」，在起點格上放一顆棋子，只能往「上」、往「右」、往「左下」的方向移動。(二)、定義：若棋子從「起點格」，按照上述規則能不重複的通過所有m×n 格子到達某一「終點格」，則對於「起點格」而言，此移動路徑稱為m×n 的「有解路徑」，其任4一「終點格」稱為「起點格」的「路徑解」。(三)、我們先研究出「基本無解區」。(四)、根據遊戲規則我們利用三種顏色將n × n 方格塗滿，並判斷出大部分的「無解起點格」。(五)、利用遊戲規則得到兩重要性質：(1)[可逆性性質] (2) [對稱性性質](六)、利用「廣義基本無解區」，當作我們[有效移動]的判斷，讓「有解路徑」快速的找出。(七)、利用本研究所稱的「平移哈式鏈」，得到[擴充解]。(八)、根據[有效移動]求出部分「路徑解」，再利用[可逆性性質]、 [擴充解] ，最後利用[對稱性性質]完成所有「路徑解」的尋找。

在我們週遭環境中常可見到許多種類的植物，然而可以叫出名字的卻少之又少，或許我們可以查閱植物百之類的書籍，但是這類書籍通常多不在手邊，就算有了植物百科，也不易翻到顯示該種植物的正確章節。假如我們可以將想要認識的植物葉片影像取得後，透過網路將該影像傳送至植物葉片資料庫查詢，經過電腦的自動分析辨識後，再將結果傳送回來，這樣不是比查閱植物百科方便多了嗎？本研究提出一種利用輸入葉片的影像來進行植物資料庫辨識查詢的方法，藉著兩階段處理的策略及最佳權重組合式的特徵值來調校系統，以達到較佳的整體辨識效能，從實驗測試的結果得知，我們的策略與方法確實有效，有82%的查詢葉片可以被精確的辨識出來，而每次查詢的平均反應時間只要17.22 秒。In our living environment, there are many kinds of plants, but we can only name a few. We may consult an encyclopedia about plants, we always can’t find any encyclopedia with us. Besides, even if we have one, it won’t be easy to find out the proper section or the exact page immediately. How should we solve this problem? One significant improvement can be expected if the plant recognition can be carried out by a computer. First, we take a picture of the unknown plant’s leaf. Then, we transmit this image into a leaf database to recognize. After the recognition we will get the answer easily. By using a computer-aided leaf recognition system, non-professionals can also identify many plant species. Isn’t it much more convenient than checking the encyclopedia? In this study, we present an efficient method for leaf database retrieval by inputting leaf images. We use a two-stage approach and combined features with optimized weight to adjust the system to get the best system performance. The result of the experiment shows that our approach is workable and efficient. 82% leaves of the query images can be recognized accurately. And in general, the average response time only takes 17.22 sec per query.

伏打電池中，若兩極的電極種類及溶液種類均相同，僅是兩極的溶液濃度或溶液溫度不同，兩極間就有電位差，稱為濃差電池及溫差電池。典型的濃差電池中 ( 電極為電解液正離子的金屬片 )，濃度大的一端電位較高，電池電壓與兩杯溶液濃度比值的對數值成正比，且在相同濃度比值時，硝酸銀濃差電池的電壓最大，其次為硝酸銅、硫酸銅，硫酸鋅濃差電池的電壓最小。硫酸銅溫差電池，若電極為銅片，則電池電壓與兩杯溶液溫度差成正比，且溫度高的一端電位較高。 我們將硫酸銅溫差電池製成太陽能電池，在太陽下曝曬3 小時，電壓可達 13.6mV， 電流可達0.76mA，因此只要串聯數個電池以提高電壓，再對鉛蓄電池充電，就可以達到方便、實用與重複使用的目的。 In a voltaic cell, if the kinds of both electrodes and electrolytes are the same, but the molality or the temperature of the solutions are different, there will be potential difference between the two electrodes. We can them molality-difference cells and temperature-difference cells. In a typical molality-difference cells－its electrode is a piece of metal which is the same kind of metal with the cation electrolyte.－the electrode with the higher molality has the higher potential, and the potential and the log of the fraction of the molality of the two glasses of solution are directly proportional, and when the fraction is the same, AgNO3 has the highest potential and then Cu(NO3)2 and CuSO4, and ZnSO4 has the lowest potential. In a CuSO4 temperature-difference cell, if its electrode is a piece of cuprum, then the potential and the temperature- difference of the two glasses of electarolytes are directly proportional, and the electrode with the higher temperature has higher potential. We use CuSO4 temperature cell to make a solar cell, and put it under the sun for 3 hours, the potential can be 13.6 m V, and the current can be 0.76m A. Therefore we can make several of them series to get higher potential and charge a lead storage battery. By this way, we can make a convenient, practical and recycled battery.

p53 蛋白是一種轉錄調控因子，其在抑制癌症的形成扮演很重要的角色。已知的報告顯示它能影響下游特定蛋白表現進而調控細胞週期或促使細胞進行凋亡作用。如此作用機制對於可能癌化的細胞在生物體造成傷害之前能被先行消滅，因此正常的p53 蛋白存在與否，對癌症的產生有很大的影響。 根據上述結果，我們想分析不同表現量的p53 是否對於致癌藥劑-EtBr所引發的癌化細胞有所影響。所以我們設計實驗，將具有正常表現量p53 蛋白的老鼠(p53+/+)與僅能表現少量p53 蛋白的老鼠(p53+/-)，均塗以等劑量之致癌藥劑EtBr於其大腿皮膚上，觀察其致癌情形的差異。實驗結果發現 : 在塗EtBr 的14 隻p53+/-老鼠中，有3 隻出現了組織病變的症狀，包括脾臟腫大，淋巴組織長出腫瘤，而其他對照組(一)塗EtBr 的p53+/+老鼠，(二)不塗EtBr 的p53+/+老鼠或(三)不塗EtBr 的p53+/-老鼠都沒有產生異常的症狀。因此根據上述實驗結果進行推論，發現經EtBr 的刺激後，p53+/-的老鼠的確較其他的老鼠更容易得到癌化細胞。;p53 is a transcription factor that plays an important role in suppression of tumorgenesis. Previous reports showed it regulates cell cycle and enhances cell apoptosis by effecting specific proteins expression. By this way, the problematic tumor cell can be deleted to protect organism from tumor damage. According above conclusion, we are interested to know whether p53 plays a role involved the carcinogens-EtBr induced tumorgenesis. We compared the differences of tumorgenesis between mice express normal (p53+/+) or low (p53+/-) expression level of p53 proteins when they are smeared equal amount of EtBr on skin of thigh. In here, our results show three of fourteen p53+/- mice had pathological changes, containing spleen enlargement and lymphoma. However, other three comparisons, smear p53+/+ mice with EtBr (1), without EtBr (2) or p53+/- without EtBr(3), are normal. Therefore, We suggest that p53+/- mice are easily to obtain tumor than p53+/+ mice after EtBr treatment.

長期以來，臨床研究發現會影響人類胚胎的正常發育，造成胚胎畸形、成長遲緩等現象，稱為胎兒酒精症候群（fetal alcohol syndrome），但是其病理機制仍不清楚。最近的研究發現斑馬魚胚胎對於酒精有非常靈敏的反應，出現明顯的發育異常現象，例如心臟膨大、眼睛縮小、骨頭變形等現象，與人類胎兒酒精症候群相似，顯示斑馬魚非常適合作為研究胎兒酒精症候群的模式動物。在本實驗中，我們針對酒精影響視網膜神經發育的現象進行探討，並且也利用基因晶片篩選出胚胎發育時期受酒精影的的基因轉錄子，藉以了解酒雞造成胚胎畸形發育的機制。實驗結果顯示在眼睛發育過程中，1.5% 酒精浸泡會抑制視網膜神經細胞的分層（Lamination），而進一步利用RNA定位雜交的方式以眼睛的標示基因rx1、pax6b、six3b、alpha-crystallin、rho、neuroＤ、huC觀察他們的表現，發現酒精會減少視網膜神經細胞的分化，造成眼睛發育的缺陷。在基因晶片的分析中，我們發現酒精處理會抑制許多控制眼睛發育的基因調控子的表現，包括了crx、rybp、irx4a、optx2、rx1、brn3b1 與 vsx1等，此外約有16%的眼睛相關基因液受到酒精的抑制，遠高於其他基因受抑制的比例，顯示眼睛是酒精傷害最嚴重的區域之一。我們從實驗結果得知酒精並未對胚胎發育初期眼睛的發育造成明顯的影響，但是隨後由於控制細胞分化的幾個重要基因受到酒精抑制作用，造成視網膜神經細胞的分化停止，引起眼睛的異常發育的情況。It was known that prenatal alcohol exposure may cause serious birth defects and developmental disabilities. The molecular mechanism of this fetal alcohol syndrome still remains unclear. Here we used zebrafish embryo as a model to investigate the toxic effect of alcohol in retinal development. The histochemical analysis revealed that the cell lamination was prohibited by alcohol incubation. It appears that the retinal cell differentiation was inhibited. As revealed by whole mount RNA in situ hybridization, it appears that the transcription of a number of retinal-related regulatory genes, including rx1, pax6b, six3b, alpha-crystallin, rho, neuroD and huC, were all inhibited in zebrafish embryo by alcohol exposure. The transcriptional profile of alcohol-exposed embryos was also compared with normal embryos by microarray analysis at different stages. It appears that 16% of retinal-related genes were all repressed by 1.5% alcohol incubation, including several retina-related transcriptional factors, including crx, rybp, irx4a, optx2, rx1, brn3b1and vsx1. Our results suggest that alcohol did not interfere the early development of the eye, but has inhibited the final cell differentiation of retina cells. This study helps us understand the molecular mechanism of alcohol-mediated retinal malformation.

根據研究結果，溫室效應使全球暖化，海洋溫度溫差變大，對流速度加快；暖流由赤道向北流，鹽度增加，流速會變慢；冷流由北極向南流，因為鹽度增加，海水密度増大，冷流無法下沉，造成流速變慢。溫度越低，鹽度會增加，密度就會變大，所以洋流會往下沉，越往下鹽度越高，當冷水跟周圍達平衡時，就不再繼續往下沉，反而會沿水平方向移動。電影「明天過後」所描述的氣候現象是指北極冰棚融化後，由於北大西洋海水鹽度降低造成全球「大溫鹽循環」（thermohaline circulation）停止，海洋從低緯到高緯的熱傳輸能力降低，使地球進入冰期狀態，美洲北部全面冰封的情景。這樣的電影場景不可能在短時間內發生。

槐葉蘋(Salvinia natnas)生長於台灣低海拔淡水濕地，目前已列為嚴重瀕臨滅絕的台灣原生物種，為不具有根的植物，是世界珍稀的漂浮型水生蕨類。本研究是探討槐葉蘋形態、生活史及生存環境因子，實驗發現可藉由成熟浮水葉外部形態特徵來區別槐葉蘋與外來種之人厭槐葉蘋(Salvinia molesta)；槐葉蘋成熟浮水葉呈橢圓形，葉上毛被物是叢生且分岔，人厭槐葉蘋成熟浮水葉呈雙耳形，葉上毛被物則像打蛋器。當兩物種共存於同一個環境空間時，人厭槐葉蘋以平均11.6 cm2/week 的生長率將槐葉蘋完全取而代之，顯示人厭槐葉蘋之入侵對槐葉蘋生存影響之深遠。經由兩年的槐葉蘋物候觀察，發現3~11 月為抽芽成長期、3~12 月為成熟繁殖期、12 月~隔年2 月為冬枯期及孢子囊果出現期，12 月~隔年5 月為孢子囊果成熟開裂期。其繁衍策略可分為無性繁殖（頂芽及側芽生長）及有性生殖（異配子體交配）。探討環境因子（光照度、氣溫、濕度、水質、水溫、pH 值）分析結果，適合槐葉蘋生存環境的條件為(1)陽光間接照射（半遮蔭，遮蔭度58.33%）、(2)乾淨未受污染的水質(pH 6.5~8)、(3)通風性良好。生長環境符合以上條件即可達到移地保育的目的。Salvinia natans, a floating fern without roots, grows in low elevation fresh water wetlands of Taiwan, and is a critically endangered precious Taiwanese native species. This research investigates the life form, life history, and living environment of Salvinia natans. Our experiments show that we can differentiate Salvinia natans and Salvinia molesta, two easily mixed up species. The shape of matured floating leaves of Salvinia natans is elliptical and smaller, while it is twin-ear shape and larger for Salvinia molesta. Also, they can be distinguished by their leaf hairs. The hairs of Salvinia natans are tufted and separated at the tips, while the hairs of Salvinia molesta form an ‘eggbeater’ shape at the tip. When these two species lived together, Salvinia molesta grew in a rate of 11.6 cm2/week and will replace all Salvinia natans eventually. This shows the profound impact of invasion of Salvinia molesta. From the data of 2-year phenology observation, we concluded that budding took place from Mar. to Nov., growing and reproducing from Mar. to Dec., decaying from Dec. to Feb. (sporocarps were born in this period), and sporocarps matured from Dec. to May. There are two reproduction strategies: sexual reproduction (intergametophytic mating), and asexual propagation (by terminal and axillary growth). After investigating the environment factors (illuminance, air temperature, water temperature, humidity, pH), we found that ex situ conservation for Salvinia natans requires 1) indirect sunshine, 2) unpolluted water (pH 6.5 ~8), and 3) good ventilation.

本研究利用偏振片、量角器為刻度盤、雷射光為光源，及照度計為偵測器，組裝一個簡易且可靠的旋光度計。我們利用單位時間旋光度的變化量當作反應速率，來測量蔗糖的水解速率，同時求出蔗糖水解反應的反應級數、速率常數(k)。利用糖類的旋光度具有加成性之特性，找出不同混合比例時的旋光度，追蹤實際蔗糖水解的每個狀態，找出最後平衡狀態，同時將蔗糖水解平衡結果顯示，旋光度與濃度有線性關係，而蔗糖水解反應對蔗糖而言為一級反應。接著，我們在蔗糖水溶液中加入不同種類的酸，探討催化劑的種類與蔗糖水解反應速率的關係。 In this research, in order to measure the optical rotation accurately without expensive equipments or complex process, we assembled a polarimeter by ourselves. With simple materials which can be found in ordinary senior high school laboratories, including a calibrated scale, a simple Luxmeter, a laser as the photo source, and other side devices. The Polarimeter ended up operating fluently and accurately. We put the laser under a tube, which has two pieces of polar screens on the top of it and on the bottom of it, ,and put a luxmeter just above the tube. When we slowly rotate the polar screen on the top, the figure shown on the luxmeter changes. By numerical analysis, we can get information about the hydrolysis of polarized substance. Secondary, we measured the optical rotation of glucose, fructose, malt sugar, galactose, and sucrose to get their specific rotation. Then we measured the optical rotation of sucrose every five minutes. By doing this, we could keep track of the hydrolysis rate of sucrose, figure out the order of reaction, and the rate constant (k) and the equilibrium constant (K). Thirdly, we used different kinds of acids into sucrose solution as the catalyst, and observed the effect. The result showed that hydrochloric acid is a better catalyst to this reaction than sulfuric acid and nitric acid. The polarimeter of this research can be used in science education of junior and senior high school. By teaching students to assemble and operate the self-made polarimeter, students can know better about optical rotation and polarized substance. Also, the interest in this experiement will add to students’ motivation to do science research.
