從2004年之台灣322事件看衍生性商品--以台指選擇權市場為例
本研究共有三個目的。第一個目的為了解2004年「台灣322事件」的來龍去脈,並推測當時投資人對於市場的看法。第二個研究目的,則是了解選擇權市場對於此類事件的反應情形,以作為投資人日後投資策略應用的參考。第三個研究目的,即是探討2004年3月23日當天,台指買權與台指賣權價格變動方向相對應台灣加權量股價指數變動方向兩者間的關係,實際觀察到的互動與理論提出的關係不相符背後可能的原因。
而所謂的「台灣322事件」是指2004年3月22日當天台灣加權量股價指數下跌了6.67%,同時台指選擇權市場方面,四月份到期各履約價格的買權價格都下跌,四月份到期各履約價格的賣權價格都上漲,呈現大起大落的現象。
至於3月23日當天所觀察到台指選擇權價格變動和理論不合的背後原因,本研究推測為投資人提高對台股指數未來的預期報酬率,故利用蒙地卡羅模擬法,模擬出3月22日及3月23日對應台股指數在依據理論模型下應有的價格,也模擬出投資人預期報酬率提高後3月23日會產生的價格。在整體市場投資人期望報酬率改變為65.13%下,比較模擬結果顯示,3月23日各履約價台指買權合約的價格的確都比3月22日的價格來得高,且各履約價台指賣權合約的價格也都比3月22日的價格還要低,這樣的結果和實際在3月23日當天所觀察到的結果相去不遠

碩士[[abstract]]近年來,在人臉辨識方面利用上已相當廣泛,辨別人是否處於疲累狀態、出入口管制及利用辨識技術,辨識出人與物體,可以進一步辨別是否有人犯罪等。另外,腦波的應用發展也相當迅速,腦波現階段可以用來分辨嫌犯是否說謊、學生對學習是否專注、在醫學上判斷是否有腦部疾病以及在運動上可幫助運動員找到最適合比賽時的狀態等。
現今用於嫌犯之人臉辨識大多處於須連線比對資料庫的情況,受害者或目擊者欲描述其印象中的嫌犯特徵時,需與警方素描師反覆確認是否為嫌犯,此過程反覆時間長,並且有時受害者或目擊者所描述的與嫌犯特徵有大部分不同,進而影響警方作業速度,或是警方在街頭遇到嫌犯或失蹤人口時,欲比對是否為嫌犯或失蹤人口,必須連線到資料庫進行比對,此過程還須等待資料傳輸時間,當網路不順或不通時,將無法即時確認是否為嫌犯或失蹤人口。
因此,本研究欲利用演化策略整合事件相關電位中的腦波以發展出一套嫌犯描繪系統,利用腦波事件相關電位的擷取系統,目擊者及受害者不需提供犯罪者的特徵,經由取得使用者之腦波事件相關電位,在系統中解出嫌犯之特徵由演化策略快速找出犯罪人素描圖,將結果顯示於系統畫面,由使用者確認是否與印象中之長相符合。
此系統可以增加警方作業速度,縮短原本素描師與目擊者及受害者反覆確認所耗費之時間,也可利用於一般使用者,欲要告知他人印象中之人物的特徵,可透過此系統,利用偵測腦波事件相關電位,得出想要描述之特徵或人物。[[abstract]]The face recognition are used quite extensive in recent years, like identify whether people are in a state for exhaustion, import ane export control and used to distinguish people or objects, can also identify whether someone in the process of committing a crime. In addition, the application of brain waves is development quite rapidly. Brain waves can be used to distinguish whether the suspects are lying and the students focus on learning. In terms of medical can judge whether has brain disease. In terms of sports can help athletes find the most suitable state of competition.
At present, the most of face recognition of suspect are connect database to compare. The victims or witnesses were describe the features of suspects confirmed repeatedly with police sketcher. This process confirmed repeatedly and time-consuming. If the victims or witnesses described the facial features incomplete resulted in suspect''s sketches were different from suspect and then affect the speed of police operations. Or the police encountered the suspect or missing persons want to be compared whether the person was the suspect or missing persons, it must be connect database to compare pictures of the suspect or missing persons, the process must wait for the data to be transmitted. When the network has bad connection, it will not to confirm whether it is a suspect or missing persons immediately.
Therefore, this project intends to use the evolutionary strategy and neural network integrate with event-related brain waves in order to develop the identification system of suspects of crime. The use of event-related potential brain waves captured, witnesses or victims were no longer to describe the features of suspects. In the system, by obtaining the brain wave event-related potential of the user, evolutionary strategy and neural networks can be used to find the criminal sketch quickly without the description of the characteristics for the offender. The result can be displayed on the system screen. And confirm the result correct or not by user.
This system can increase the speed of police operations, shorten the sketch and witnesses or victims confirmed repeatedly and time-consuming, can also be used for general users. Through this system, by detecting the brain waves event-related potential and use evolutionary strategy to describe who you want to tell others the features of the character in the impression.[[tableofcontents]]目錄

This study investigated participation in post-baccalaureate in-service education and professional development among preschool teachers in central Taiwan. The methodology was based on questionnaire survey. The “Questionnaire on Participation in
Post-Baccalaureate In-Service Education and Professional Development” was used. A total of 1012 teachers from kindergartens or day-care centers in Taichung City, Changhua
County/City, and Nantou County/City participated in this survey. The collected responses were processed and analyzed using methods including descriptive statistics, independent
sample t-test, and one-way ANOVA. From research findings, the following conclusions were obtained:
1. Most of the preschool teachers in central Taiwan had a high intention to attend post-baccalaureate in-service education
(1)The primary incentives for the preschool teachers in central Taiwan to attend post-baccalaureate in-service education were “increase professional knowledge in education”, “fulfill personal career plans and goals”, and “meet the trend of the
times”. Among the professional courses of in-service education, “courses related to counseling preschool children” were most demanded. The main barriers to their participation were “high instructional and administrative workloads” and “a fear for
heavy schoolwork”.
(2)Overall, “unmarried” teachers showed a higher intention for in-service education
than “married” ones.
(3)Teachers who were “married”, having a “vocational school” education background,
“not a certified teacher” or teaching in “day-care centers” perceived more barriers to their participation in-service education than teachers who were “unmarried”, having a “college” education background, “a certified teacher” or teaching in “kindergartens”.
2. Most preschool teachers in central Taiwan had a positive attitude toward and recognition of their overall professional development (1)Teachers who were “married”, “senior”, having an “above graduate school” education background, “a certified teacher”, “previously or currently studying in graduate program”, and teaching in “kindergartens” located in “Taichung City” and having “31~60 students” showed better overall professional development. 3. There was a significant relationship between participation in post-baccalaureate in-service education and professional development among preschool teachers in central
Taiwan (1)The “overall dimension” of participation in post-baccalaureate in-service education as well as its subdimensions, “incentive” and “curriculum needs”, were all significantly
related to the “overall dimension” of professional development and its subdimensions, “professional knowledge in preschool education” , “teaching techniques” , and “professional attitude”
