神經網路模型於金門空氣品質PM2.5 預測

為了解決power bi書的問題，作者黃靖涵 這樣論述：

鑒於近年來全球工業產業蓬勃發展，各產業在環境保護及永續發展等意識越來越重視，並且政府在針對造成空氣品質污染的管控也相對要求，在這全球化的現今，不論身在這世界的哪一個地方，都希望能夠維持良好空氣品質的生活環境。金門地區造成空氣品質不良的原因，主要為風面強大、氣候乾燥等因素引起的揚塵所致，因為地理位置與氣候的之間的關係，空氣品質的因素也受中國大陸南下空氣影響，其針對空氣流動、氣流穩定度與氣候間的變化，都足以影響到空氣品質的好壞。所以，本研究中蒐集金門地區監測站自2011年1月到2020年12月每天的氣象偵測平均數據，做為本論文的研究資料，其中蒐集的氣象資料內容，包含了相對濕度（%）、溫度（℃）、

風速（m/sec）、降雨強度（mm）與氣壓（hPa）等，並將歷年的觀測數據，彙整的資料做適當整理後，先透過大數據分析，證明上述的氣象資料是會影響空氣污染物擴散的因素，再將相對濕度（%）、溫度（℃）、風速（m/sec）、降雨強度（mm）與氣壓（hPa）等5項影響因素，透過倒傳遞類神經模型（Back-Propagation Neural Network，BPN），來實驗多組的模擬訓練與進行空氣污染物擴散的預測。本研究將空氣污染物細懸浮微粒PM2.5分成50μg/m3以下和51μg/m3以上的二個級距，並依據不同的影響因子組合，進行每天空氣污染物的擴散預測，準確率最低為86.7%，最高可達88.5%

。依據實驗的測試結果，可證明使用倒傳遞神經模型進行金門當地空氣污染物擴散的模擬與預測是可行性的；但是天氣變化多端，金門島嶼型的氣候更是千變萬化、變幻莫測，因此可以再增加更多會影響空氣品質擴散預測的因素，並且結合其他不同預測方法與演算法，以取得更精準的預測結果，以提供金門當地氣象預測之參考，同時也能提供當地民眾外出時的防範作為。

At the President’’s Table: Food, Politics, and the History of Breaking Bread at the White House

為了解決power bi書的問題，作者Prud’homme, Alex 這樣論述：

A wonderfully entertaining, often surprising history of presidential taste, from the grim meals eaten by Washington and his starving troops at Valley Forge to Trump’s fast-food burgers and Biden’s ice cream--what they ate, why they ate it, and what it tells us about the state of the nation--from

the coauthor of Julia Child’s best-selling memoir My Life in FranceThe American presidents have been hosts to some of the most significant moments in our history over meals at 1600 Pennsylvania Avenue. And during such occasions, our commanders-in-chief have understood the value of breaking bread wit

h both friends and foes--Thomas Jefferson’s nation-building receptions in the new capital Washington, D.C.; Ulysses S. Grant’s state dinner for the king of Hawaii; Booker T. Washington’s groundbreaking supper with Teddy Roosevelt; Richard Nixon’s practiced use of chopsticks to pry open China; Jimmy

Carter’s détente between Israel and Egypt at Camp David. Here, Alex Prud’homme invites readers into the White House kitchen to reveal the sometimes curious tastes of twenty-six of America’s most influential presidents, how their meals were prepared and by whom, and the ways in which their food polic

ies affected people around the world. As each president grew into his distinguished role, his personal tastes evolved White House menus over time--from simple eggs and black coffee for Abraham Lincoln during the Civil War and celebratory turtle soup after, to squirrel stew for Dwight Eisenhower, jel

ly beans and enchiladas for Ronald Reagan, and arugula for Barack Obama. What our leaders say about food touches on everything from our nation’s shifting diet and local politics to global trade, science, religion, war, class, gender, race, and so much more. Prud’homme also pulls back the curtain on

overlooked figures like George Washington’s enslaved chef, Hercules Posey, whose meals burnished the president’s reputation before the cook narrowly escaped to freedom, or pioneering First Ladies, such as Dolley Madison and Jackie Kennedy, who used food and entertaining to build political and social

relationships. As he weaves these stories together, Prud’homme reveals that food is not just fuel when it is served to the most powerful people in the world. It is a tool of communication, a lever of power and persuasion, a form of entertainment, and a symbol of the nation. Included are ten authent

ic recipes for favorite presidential dishes, such as: Martha Washington’s Preserved CherriesAbraham Lincoln’s Gingerbread MenWilliam H. Taft’s Billy Bi Mussel SoupFranklin D. Roosevelt’s Reverse MartiniLady Bird Johnson’s Pedernales River Chili

B2B會展參展商展位人員的個人特徵、互動行為及交流表現

為了解決power bi書的問題，作者盧盟方 這樣論述：

企業對企業(B2B)會展被視為行銷人員與現有和潛在顧客進行聯繫的成本效益措施(Bello&Barksdale,1988;Lilien,1983)。 此外，它們被視為企業資訊收集、產品曝光、關係建立和組織學習的寶貴渠道(Hansen,1996;Kerin&Cron,1987; Li,2006)。B2B會展作為行銷媒體的組成部分，為產業買賣雙方提供了一個進行交易、關係和資訊交流的良好平台(Siemieniao&Gębarowski,2017)。現有的展覽文獻缺乏對B2B會展背景下展位人員-展覽參觀者二元互動的前因和後果的系統性和理論性調查。從社會交換理論的角度來看，這項研究的主要目的是研究被忽視

但關鍵的主題，希望提供有趣的理論討論和管理建議。具體而言，本研究試圖發展和測試與展覽相關的模型，該模型的構建旨在找到有關展位人員與參觀者互動的三個問題的初步答案。一、個人特質是否會影響展位人員的互動行為？二、展位人員的顧客導向行為是否可以調解個人特質與互動行為之間的聯繫？ 三、展位人員的互動行為是否會影響參觀者對展位人員的資訊績效和關係績效的評估？本研究模型包含三個主要組成部分。一，展位人員的個人特徵包括以下因素：尋求挑戰(challenge seeking)、工作樂趣(task enjoyment)和外向性格(extraversion personality)。二是展位人員的互動行為，包括資

訊蒐集(information gathering)、B2B會展的關係行銷視角(Relationship Marketing Perspective)和關係綁定(relationship bonding)。三是兩個變數代表展位參觀者在對展位人員的資訊績效(informational performationce)和關係績效(relational performance)的評估。此外，本研究還探討了顧客導向(customer orientation)對個人特徵和互動行為之間Relationship Marketing Perspective的中介效果。 最後，本研究表明：一、內在動機、外向性格和

顧客導向是展位人員互動行為的重要先決條件。二、二元數據表明互動行為與展位參觀者的信息和關係表現密切相關。三、展位人員的顧客導向積極地調解了內在動機和互動行為因素之間的關係。四、展位人員的顧客導向積極地調解了外向性與互動行為因素之間的關係。
