台灣地區在七、八月份常會受到颱風的襲擾,在臺灣民間流傳「一雷破九颱」這句諺語,常為一般人誤解,認為聽到雷聲,颱風就不會來了,但是「一雷破九颱」真的就是一雷破九颱嗎?其實不然。本研究利用 1996 年到 2000 年此期間的颱風之氣象衛星資料,加上台灣電力公司自 1990 年開始,在台灣地區裝置雷電偵測系統,測量台灣地區周圍雲對地放電的時間、位置、強度、極性等,對一雷破九颱的疑惑做一探究。而研究結果顯示,颱風與落雷並沒有絕對的關係,而一雷破九颱也不代表颱風來了就沒有落雷的發生,或者聽到雷聲有落雷發生,而颱風就不會來。但在颱風暴風圈登陸台灣至出海(離開台灣)期間,落雷量明顯減少,而分布上也不再侷限於台灣本島主要落雷發生區,在台灣四周海面上,都有落雷分布的情形。

金門本島之基磐組織大都以花崗片麻岩為主,但由於長年受到風化、淘洗、沉積的影響,因而造成了陸上坡崗起伏,質土種類繁雜;其中包含有白淨的矽砂,乳白色的陶土、黃色的鋁土、紅色的黏土、土黃色之砂質壤土,以及各種不同的岩石和礦物等,其中以沉積之紅土礫層在本島上分佈最廣,且形成了各種紅土台地,地層的頭色大部份由暗紅色至橙黃色之含礫泥質砂岩和含礫砂質黏土所組成”雖然土質貧瘠,不宜耕作,但其中卻富於礦質,可供開採。而且若能利用各種改良方法,也可開墾種植一般耐早性雜糧作物,如:花生、甘藷、高梁 … 等,以增進刪羸農民收益。每當上班途中,看到路旁紅土遍地,大都無人利用,雖然有幾處已在政府的輔導下開闢為農地(如:普果山一帶),其餘的也都種植樹木,以利水土保持,其實紅土變為農地,若能改良得宜,其作物成長比一般土壤為佳,且紅土層內夾雜了不少的礦物,雖有部分已在進行開採,但大部分礦物扔尚待開發與利用。如上述理由,引起我們對地區紅土礫層研究之興趣,並期望藉此研究能使全體軍民對紅土礫層作更進一步的認識與利用且能提供有關單位參考。

在高一下學期三角函數課程中我們學到正餘弦疊合函數,f(x)=asinx+bcosx,我們發現給予不同之參數a、b與x值除了可以得到不同之f(x)之外,若藉著一系列之疊代獲得之a、b與x亦可求得一系列之當作換位加密時之移位使用,其優點是可以讓資料之換位次序非常凌亂,提高資料保密之安全性。 f(x)在高一上學期整數單元中學到輾轉相除法原理,輾轉相除法除了求得兩個較大正整數之最大公因數之外,利用輾轉相除法之求解過程中,可以將一個最簡假分數化為簡單連分數型式。因此可以利用此簡單技巧作為一個正整數數列與最簡假分數的應對工具達成明文與密文之轉換作為加密與解密工具。\r 另外整數單元中也學到同餘運算,可以解一些較大正整數之間除法運算的餘數問題,RSA加密方法即利用此方法達到增加解密之困難度。\r 我們將以上三種方法適當結合而提出我們新的加密與解密方法,稱為「三重加密法」,其優點可達成資料壓縮與資料保密之效果。

Molecular and Cellular Responses under Hypoxic Stress among Rice Cultivars with Different Flooding T
全球暖化造成水災頻繁,嚴重威脅植物生存。看似耐淹水的水稻,在完全淹水下亦有其生存危機。水稻FR13A 因耐水性極佳而常用於分子育種,IR64 產量高卻不耐水。是那些特質使稻種間有不同耐水機制?我們觀察其幼苗淹水24 小時後生長情形、通氣組織 (aerenchyma) 變化及應用即時反轉錄聚合?鏈反應 (real time RT-PCR),研究酒精醱酵的主要蛋白質:乙醇脫氫? (alcohol dehydrogenase, ADH1, 2) 及丙酮酸脫羧? (pyruvate decarboxylase, PDC2) 基因之表現量。兩種水稻的胚鞘及根都因淹水減緩生長,以FR13A 減緩最明顯。通氣組織在淹水期間都有增加,FR13A 中的形成近似於對照組,IR64 則明顯較差。FR13A 中ADH1 及ADH2 在淹水一小時後迅速增加60 至100 倍,IR64 僅增加10 至20 倍。PDC2 在IR64 中表現量的增加幅度較大,但最大值仍小於FR13A 之基礎表現量。由此可知,FR13A 在完全淹水時成長減緩而原有通氣組織則持續生長,且酒精醱酵中的基因有獨特誘導反應,因此耐水性較佳。藉由此研究揭開水稻細胞及分子生物學上的耐水反應策略,將可更精準地改良稻作使其對抗淹水逆境,解決未來因環境造成的糧食危機。Global warming increases the frequency of flooding, which drastically reduces the growth and survival of plants. Although rice (Oryza sativa) appears well-adapted to flooding of roots as it is often farmed in paddies, problems arise when the whole plant is submerged in water. I am interested in the structural and molecular responses that result in different submergence tolerances in rice cultivars. Indica rice FR13A is submergence-tolerant and frequently used in molecular breeding for this trait, while IR64 is a high-yield but submergence-intolerant cultivar. In this study, I monitored the growth rate, aerenchyma formation, and gene expressions of the carbohydrate metabolism in FR13A and IR64 seedlings subjected to submergence for 24 hours, by means of real time RT-PCR and microarray. FR13A had prominently inhibited coleoptile growth and sustained levels of aerenchyma formation whereas IR64 did not. The mRNA levels of alcohol dehydrogenase 1 (ADH1) in FR13A was induced prominently, while ADH2 was induced in IR64 during early hours of submergence. The induction of pyruvate decarboxylase 2 in FR13A was stronger than IR64. The expression of sucrose synthase was similar in both strains. Expressions of the genes involved in anaerobic carbohydrate metabolism were also studied by analyses of microarray data. My findings demonstrate that elongation quiescence, persistent aerenchyma formation and shifts in anaerobic carbohydrate metabolism gene expressions are beneficial strategies of FR13A towards submergence. Through elucidating the molecular basis of coordinating submergence tolerance genes as this study provided, it will be possible to discover multiple traits associated; hence crop improvement for flooding tolerance could be achieved.
