The study aimed to compare the electricity generated from the fruit extracts of calamansi, camias and starfruit. Unripe fruits were extracted and varied percentage compositions of each extract were prepared.Wires wereconnected to a multi-tester (voltmeter or ammeter) to measure voltage or current that passes through. Results revealed, that amount of voltage and electric current generated are its lowest reading at 25% and are its highest reading at 100%. Nonetheless, of the three fruit extracts, it’s the calamansi that has the highest amount of voltage generated of0.97 volt while camias has the highest amount of electric current generated of 13.98 mA. Using ANOVA at 0.05 level of significance on the amount of voltage generated among varied percentage compositions of three extracts. However, there’s a significant difference on the amount of electric generated among varied percentage compositions. Results of ANOVA statistically signify that the three different extracts could either be used as a source of voltage and that camias extract should be preferably used over the other two fruit extracts in generating electric current. In all compositions, produced voltage is between 0.88 and 0.97 volts and current is between 3.28 and 13.98 mA. These currents produced are not enough to turn on a small light bulb having a smallest voltage capacity of 1.2 volt, but can be able to turn on a light-emitting diode (LED) that require such amount of current.

數字波是探討在直線上的起始點、位移速度、總數相互變化的節點關係。在直線上，將全部格子數做為總數(m)，開始彈跳的點為起始點(i)，每次彈跳的格子數為位移速度(s)，被踩到的格子就是節點。節點是由位移速度和起始點決定，起始點本身可視為節點之一，之後的節點是由起始點加n 個位移速度產生。我們分別以三種型式討論：起始點等於位移速度，總數增加：使起始點和位移速度所代表的數字相同的彈跳。節點呈2、s、s+2…起始點固定，位移速度與總數增加：觀察位移速度和總數的關係。兩節點的和=s+2位移速度固定，起始點與總數增加：探討起始點和總數的關係。發現節點隨起始點有規律的變化在上述討論的型式中，我們再進一步將位移速度分為質數和合數，進而依其因數變化，可觀測到很多特殊的節點變化。The number wave is to discuss the relationship of the starting point, the moving speed, and the variations of total amount. In straight lines, let all the trellises be total amount (m), and let the starting jumping point be the starting point (i). The trellis number of each jump is the moving speed(s). The trodden trellises are knots. And knots are decided by the moving speed and the starting point. The starting point itself can be viewed as a knot. The following knots produce with the starting point and n moving speeds. We respectively discuss them in three types: When the starting point equals the moving speed, the total amount increases. The number of the starting point is the same with the jumping moving point; the knots are 2, s, s+2…. When the starting point is fixed, the moving speed and the total number increase. From observing the relationship between the moving speed and the total number, the sum of two knots is s+2. When the moving speed is fixed, the starting point and the total number increase. After our research into the relationship between the starting point and the total amount, we find the knots have regular variations with the starting point. From the types discussed above, we further divide the moving speed into prime numbers and non-prime numbers. Furthermore, according to the factor variations, we can see a lot of specific knot variations.

This is a study about the solution to a chess flipping game. The game is based on a 4*4 game grid. First, place some chesses on the grid randomly to start a game. Move any chess by jumping over one or two neighboring chesses in the same row (left or right), same column (up or down), or on the same diagonal. Chesses which get jumped over should be flipped. The ultimate aim is to make all the chesses upside down. In this study, I try to find the rules of the beginning arrangement that ensure solution. Here are the steps I take: First, break the restriction of the 4*4 grid, and set the coordinate system. Second, find out a few “basic illustrations” that can be solved and moved in order to cope with certain complicated problems. Third, with “basic illustrations”, find the rules applying to games on n*n grid. 這是關於翻棋遊戲的可行解之探討。棋盤是一個4*4 的方格，遊戲開始時在棋盤上任意擺上一些棋子，均是正面朝上，利用相鄰棋子的水平、垂直、斜向跳躍，棋子被跳躍過一次則翻面一次，遊戲目的在於使所有的棋子都翻為反面。我要探討的是關於棋局可解不可解的問題，找出棋盤上可解棋局的規則。研究步驟大致如下：一、打破棋盤4*4 的限制，將棋盤座標化。二、找出若干個可解並可移動的「基本圖」。三、利用基本圖，找出n 列棋盤可解的規律。

藉由結合液晶與奈米線，本研究設計出新型的光電元件，我們發現這些新設計具有先前元件很難達到的新穎特性。首先，我們研究液晶分子與一維磁性奈米線之結合，很有趣的是磁性奈米線在液晶元件內，會沿著液晶方向作整齊排列，更重要的是經由一外加電場，即可調控磁性奈米線之磁場方向。藉由電場調控磁場，是很久以來許多科學家追求的目標，然而成效不彰，本研究提供了一個簡便的方法，克服了長久以來的障礙。第二個例子，我們研究液晶分子與一維半導體奈米線結合之元件，我們證實了半導體奈米線所發射瑩光之電場偏極方向，可以經由外加電場來調控，這個特性對於資訊科技的應用，將很有用處。本研究所觀測到之結果，皆可利用下列事實來理解，奈米線具有很大的表面積，因而增加了與液晶分子之交互作用，經由此增大的交互作用力，奈米線會沿著液晶分子方向排列。值得強調的是，本研究利用了已成熟的液晶顯示器技術，其未來應用性將有很大潛力。New devices based on the composites of liquid crystals and one dimensional nanowires have been designed, fabricated, and characterized. It is discovered that these novel devices own interesting properties that are very difficult to be obtained by conventional ones. As the first example, the liquid crystal device with built-in one dimensional magnetic nanowires has been studied. It is found that the magnetic nanowires can be well aligned along the orientation of liquid crystal molecules. Quite interestingly, the direction of the magnetization of magnetic nanowires can be easily manipulated by an external electric field at room temperature. The phenomenon of electric manipulation of magnetization has been studied since nineteen century, but the achievement is rather limited. Here, we provide a convenient alternative to overcome the long quest search. For the second example, the liquid crystal device with built-in semiconductor nanowires has been investigated. We demonstrate that the polarization of the emission arising from semiconductor nanowires can be easily controlled by an external electric field, which is one of the basic requirements for information technology. All of our observed results can be well understood in terms of the inherent nature of a large surface to volume ratio of one dimensional nanowires, which induces a strong interaction between embedded nanowires and liquid crystal molecules. Therefore, the nanowires can be driven along the orientation of liquid crystal molecules. It is stressed here that our newly designed devices are based on the well established liquid crystal display technology and therefore their practical application can be realized in the near future.

File compression has become a very important tool in the technology field because it allows faster data transfer rates over the internet and decreased file size on data disks. File compression aims to reduce file size while still retaining the quality of the file. Lossy file compression methods are not very efficient because the compressed files end up losing more data than what is usually intended causing a considerable loss in quality. Lossless file compression methods, on the other hand, take time to process since they require decompression to retrieve the original file. In this study, a lossless algorithm which does no require decompression was created. The resulting Fractal File Compression (FFC) algorithm contains two parts, the IFS algorithm and the Huffman Tree generator. Both algorithms were created using Java language and JCreator. The finished program was tested on an image file with 2542 x 1944 pixels dimensions. The image file was compressed using JPEG, BMP, PNG and FFC formats. For each method, the image file was compressed at three different resolution settings; low, medium and high. All the compressed images were then viewed under 500% zoom using Adobe Photoshop CS2. In an area of 40 by 40 pixels, the number of distinct boxes, which served as a measurement of image quality, was determined. Compressed images for JPEG, BMP, and PNG for both the low and medium settings have low image qualities, while the fractally-compressed images have a high image quality. For the high resolution setting, both JPG and fractally-compressed images have Page 2 of 2 high qualities while BMP and PNG still have low qualities. Based on the measurements obtained from the box-counting method and the file sizes, the absolute image quality for each compressed image was calculated. The absolute image qualities of the compressed images used for each setting were then compared. Coupled with large file size and small pixels per area count, the conventional methods have lower absolute image quality than the images compressed using the FFC method. This was true for the low and medium settings, however, JPG compression has a higher absolute image quality than the fractally-compressed images. This meant that JPG compression is more efficient than fractal compression when an image has a high resolution. The resulting FFC algorithm is lossless since it uses pattern searches and replacements in order to decrease the file size. To make the program more suitable for high resolution images, the FFC algorithm may be modified. Most of the changes in the FFC algorithm should be done in the IFS generator. High resolution images can be compressed fully if the pattern that was used for compression is more representative, but even shorter. A more representative bit pattern would create a high quality, high resolution image with a smaller file size.

本研究自2002 年4 月至2003 年5 月為止，共14 個月，於台北市金面山區\r 南麓溪谷及生態池，以Twitty 去趾法(toe-clipping method)對拉都希氏赤蛙(Rana\r latouchii)進行族群特性和生殖策略之研究。\r 研究期間內共標記了580 隻(包含畸形蛙65 隻)，而雌蛙有190 隻(包含雌畸\r 形蛙19 隻)，雄蛙有350 隻(包含雄畸形蛙43 隻)，無法分辨公母者有30 隻(無畸\r 形蛙)，未判定公母者有10 隻(包含畸形蛙3 隻)。\r 在族群特性的部分，拉都希氏赤蛙之雌、雄個體吻肛長、體重及吻眼比皆\r 有顯著性差異(p

在遞迴式an+2＝|an+1|－an中簡單的代入幾個值，發現有九個一循環的現象。在一番巧思之下，我們先證明：函數f1(x)分別為1及-1、f2(x)＝x，且fn+2(x)＝|fn+1(x)|－fn(x), ?n?N， f5(x)與f6(x)圖形對稱於x＝1/2，進一步證得遞迴式循環，再將初始值伸縮至a1, a2為任意實數值。解法固然令人拍案叫絕，但令我們深深著迷，決定投入大量心血在此研究的原因，乃是遞迴式an+2＝β|an+1|-an，當0＜β＜1時，點(an, an+1)構成遞迴圖形的種種現象。 我們大量使用了函數及圖形分析的方法，定義函數fβ(cosθ, sinθ)＝(sinθ, β|sinθ|-cosθ)，發現f (n)β皆為 ?連續函數；?一對一；?(cosθ, sinθ)逆時針旋轉時f (n)β(cosθ, sinθ)同樣逆時針旋轉。藉由上述的性質推得遞迴圖形?在角度上稠密；?形狀與初始值無關；?初始值的改變產生相似的遞迴圖形。 在研究過程中，發現β＝0.86的遞迴圖形有別於其他β值，有待未來，我們四人能一窺遞迴圖形的終極密碼。

實驗初期以膠體水晶模擬岩層，模擬雪山隧道水平傾斜約 1°，製作壓克力模型(實驗一)，證明是否如賈儀平教授所言《雪山隧道＝水脈改道》註3，同時此模型也證明隧道防水襯墊完工後，和隧道開挖時水力梯度的明顯變化。再加上訪問坪林到宜蘭圓通寺一帶居民結論是：1. 雪山隧道對翡翠水庫的影響不大，但對宜蘭方面影響很大2. 模型的數據證明『隧道剛開挖因為出水嚴重出現明顯梯度外，其餘二組都不再有特定梯度，即使隧道處也沒有明顯變化』。證明隧道的水平角度對水也沒有太大導引作用。因為隧道的比例對一座山而言相當小，不會有太大的影響。3. 證明隧道防水襯墊完工後，和施工前(隧道未開挖)是同一狀況。釐清對翡翠水庫影響不大後，重心改為宜蘭。此時我們綜合中興工程資料及地調所資料理出“交錯正斷層的破碎岩體”應是大漏水的原凶！1. 於是用實驗一模型加入“破碎岩體” (實驗二)證明破碎岩體水力梯度的明顯變化。2. 再加上訪問頭城附近社區，了解居民因應大漏水後改變取水層的應變措施。3. 於是再設計模型(實驗三)證明不同不透水層的相互關係。實驗末期再度訪問頭城附近社區，赫然發現水稻已開始種植(去年還荒蕪，居民抱怨連連)看到綠意盎然的稻田和笑逐顏開的居民，我們的照片和實驗數據願為雪山隧道工程做個平反！The experiment began by using gel-crystal model to simulate rock strata and the acrylic model to simulate the dip angle of 1° of the Syue Mountain Tunnel. The experiment aimed to prove if the building of the Syue Mountain tunnel will change the water tunnel as Professor Yi-Ping Jia has indicated. The model also shows the obvious change brought by the membrane lining layed on the Tunnel and the dip angle of the water power gradient when the Tunnel was built. The conclusion of our interiew with residents in the Ping-lin and Yuan-Tong Temple in I-lan is as following: 1. The building of the Syue Mountain Tunnel has more impact on the I-lan than Fei-Tsui Reservoir. 2. The statistics of the model proved that Syue Mountain only showed gradient in the beginning when it was built. The Tunnel itself did not show any obious change. The dip angle of Syue Mountain Tunnel did not draw water due to it is small in size compared to the Syue Mountain. 3. The Syue Mountain Tunnel remained unchanged after the membrane lining was layed. After we can clarify that the Syue Mountain Tunnel has less impact on the Fei-Tsui Reservoir, we turned our attention to I-lan. We combined the information provided by Zhong-Xing Construction and the Central Geological Survey, and found that the cross-normal fault if the cause of the leakage. 1. The second experiement was conducted by adding fractured stones to the previous model and proved these stones will cause the obvious change to the water power gradient. 2. We have conducted another to the communities around Tou-cheng and realized that residents have changed the water supply strata in response to the leakage. 3. Finally, we built another model in 3rd experiment to prove the relationship of 3 water proof stratas. At the end of our experiment, we returned to Tou-Cheng and found that residents have started to grow rice and started to have simle on their face. Our experiment and statistics can do Syue Mountain Tunnel justice.

I came up with the idea to build a small submarine after researching the internet and discovering the problems in which divers had to face in dangerous and time consuming tasks. The Remotely Operated Vessel (ROV) was designed to perform hull inspections on boats to look for hull damage and leakage of contaminates such as oil or other chemicals into the water. Search, rescue and recovery, are also common tasks which need to be carried out by the police when searching for objects and items. The ROV has been constructed at a reasonably low cost for submersing in depths down to 10 metres. It is remotely operated therefore needing a tether cable to link up between the computer and the vessel. I built a computer case-top from parts that I already had to eliminate the need for an expensive laptop. A program that I wrote in QBASIC interprets input data from the operator and sends out signals to the various operations on the vessel such as to dive, surface, propel, etc. The entire project consisted of five individual technology processes. Key processes such as Propulsion, Maneuverability, Dive & Surface capability, Imaging system, and the Control system. Each process required a cost effective and practical solution but still needing to function efficiently and be low maintenance. Through continuous testing and trial & error I feel I came up with the best possible solutions with the limited amount of time and money I had to spend. I wouldn’t have got as far as I have without the help and support from friends, family and local businesses. They helped with ideas and advice from time to time, help with funding, and the sponsorship of materials and tools. Now that the ROV is complete, I have been able to trial and test it in a swimming pool. Apart from discovering a few minor leaks in the hull and ‘bugs’ in the computer program, I was able to witness the success of the vessel under operation and find any improvements that could be done to make it work better in future. With further more tests at greater depths the ROV will soon be at the stage where it can perform hull inspections of boats and find lost objects and items underwater. I feel it has the opportunity to be a marketable device to underwater industries all over the world.

1. Introduction Passive method is widely used for measuring air pollutant for one day to several weeks. This method can be used easily and doesn’t need electricity, but expensive devices are needed for measuring substances, so this is not suitable for high school students for measuring or investigating. Then, we focused on the reaction, in which Indigo, the blue pigment, is discolored by ozone, and we built up a hypothesis, that indigo is suitable for measuring ozone concentration. 2. Experimental Section We soaked a 10 mm×20 mm filter paper in an indigo solution, including hosphoric acid. Then, they were dried in an automatic oven. 5.5 cm×10 cm PTFE sheet was fold in two and five sheets of indigo filters were fixed inside (passive sampler). The passive samplers were fixed on a stand and exposed to ozone in the atmosphere. After a few days, we collected the samplers and put each indigo filter and 4.0 mL of ion-exchange water into sample tubes. Then we shook this and extracted the color pigment. We had the average value of 600 nm from the five sheets as a measure value. 3. Results and Discussion The total amount of ozone for one to seven days measured in the experiment was directly proportional to the amount of ozone measured by Osaka Prefecture. We found that we can measure ozone in atmosphere using our method. Passive method has an advantage: it can be carried out easily. We employed this trait and measured ozone concentration at 23 points simultaneously in the north of Osaka for 48 hours. We made the map of ozone concentration by marking on a blank map. The map we made was just like the map published by Osaka Prefecture. We expect that this method will be useful in measuring ozone, where measuring devices are not available. 4. Conclusion We succeeded developing new method for measuring ozone in the atmosphere by passive method using indigo, the blue pigment.

COP8 is the second unit of COP9 signalsome. In the comparison of BLAST ,we found that\r LLPC14 cDNA and the protein sequence are quit similar to the COP8 of Arabidopsis thaliana\r Therefore, we are interested in the role that COP8 plays in the photomorphogenesis and try to find\r the length of the sequence. So far, no result is obtained about the 3’-RACE, but we’re surprised to\r find that the sequence found in 5’-RACE is shorter than what we’re know, which suggests the RNA\r length of the cDNA used in the RACE combination has decreased.\r Although the final results of the COP8 5’and 3’-RACE haven’t been achieved, it is sure the\r COP8 is highly-conserved in many species. Since the similarity between LLPC14 and the COP8 of\r Arabidopsis thaliana is as high as 90 percent, we used the COP8 of Arabidopsis thaliana to detect the\r COP8 protein in pollen.在過去種綠豆芽的經驗中，不難發現它本身因為環境的不同，而有不同型態白化\r 的現象，例如：黑暗下萌發的豆苗。但尚未深入去理解白化的原因；而在後來的種植\r 經驗上，也發現有許多令自己覺得困惑的相同處。\r 在高二的生命科學第四章中，有提到光照與黑暗生長的植株，在構造比較上有明\r 顯的不同；其中，提及植物的活性組織存在「光敏素」（phytochrome），此色素蛋白的\r 存在於光照後，會引發一連串反應，至此，也稍微了解植物的萌發反應的差別。\r 故藉由個人在中研院植物所的資優生培訓過程，便以此為前題,進一步探究植物基\r 因組COP 8 與白化現象的相關性
