　　2020奧運會吉祥物讓東京一夜之間受到全球矚目，極大推動城市形象的傳播；熊本熊的爆紅推動熊本縣旅遊產業，周邊產品及海外版稅收入高達45億元，形象遍佈全球；登上《時代週刊》封面並現身美國阿波羅10號的NASA吉祥物史努比，全球擁有3億5千萬粉絲，年度版稅收入超千萬美元；印有米菲兔的嬰兒產品、家居用品及相關周邊產品，銷路遍佈全球，推動多方產業；韓國最大的通訊軟體公司LINE的吉祥物Line Friends擁有超過100種授權交易，及130多家品牌旗艦店; 而與最火男團BTS開發的新角色BT21相關的產品更是在紐約發行之日就一掃而空；從影視中走出來的帕丁頓熊極大地宣傳了英國的文化，推動了旅遊業的

發展。 　　無論是大型組織，還是小型企業品牌，吉祥物已經成為宣傳和推廣的重要手段。通過這些角色的包裝，為品牌樹立獨特形象、增加產品的附加值從而帶來巨大收益。 　　本書從吉祥物設計出發，剖析吉祥物設計要點，深度分析米菲兔、史努比、帕丁頓熊、Line Friends、BTS、東京2020奧運會等知名的案例，讓每位讀者都能靈活地運用吉祥物提升品牌效益,掌握吉祥物設計的吸金之道！ 　　The mascots for the Tokyo 2020 Olympic Games came into global spotlight overnight, strengthening the promot

ion for the city considerably. The popularity of Kumamon has generated over 124.4 billion yen in revenue from tourism, peripheral products and copyright licenses. Snoopy, once featured on the cover of Times and mascot for NASA, has over 350 million fans around the world. Its copyright income is more

than 10 million dollars a year. Miffy has expanded its global market through worldwide collaboration with brands of baby products, household supplies and many others, driving the development of various industries. LINE, a South Korean messenger application, has made over 100 kinds of license transa

ction for its official characters Line Friends, and opened over 130 flagship stores around the world. Its products with new characters BT21, a collaboration project with popular boy band BTS, were sold out on launch day in New York. Paddington Bear, who came from film and television, has taken an im

portant role in promoting British culture and tourism. 　　Mascots are undoubtedly a significant means of promotion and advertising for either large-scale organizations or small business. A brand armed with a well-designed mascot tends to establish a unique image in the market and benefit from sales

growth. Mascot Design has teased out the key points of mascot creation, and given in-depth analysis of classic case studies such as Miffy, Snoopy, Paddington Bear, Line Friends, BTS, and the Tokyo 2020 Olympic Mascots. If you wish to design a mascot that hits a home run, or aim to increase business

profitability with mascots, this is a book for you!

以冷凍乾燥法製備鈦酸鋇 /ꞵ 三鈣磷酸鹽 /膠原蛋白複合支架與性質鑑定

為了解決BT21 official的問題，作者吳亭葦 這樣論述：

針對牙周病與蛀牙問題，患者容易有齒槽骨萎縮之症狀伴隨出血等情況。本研究開發一種治療牙齒脫落後造成的齒槽骨缺損之填充材料應用於齒槽骨保存手術。本實驗設計此填充材料含有三種成分：壓電陶瓷鈦酸鋇（BT）、β-三鈣磷酸鹽（β-TCP）和膠原蛋白。 BT具有人骨的壓電特性，可自發極化產生電訊號刺激骨生長，β-TCP具有良好的生物降解性，膠原蛋白能起到凝血作用，有助於術後止血及修復，並透過冷凍乾燥法在填充材上建立孔洞，提供組織和血管的生長空間。基於上述優點，填充材預計可提高患者齒槽骨的恢復速度，縮短療程，從而減輕患者的痛苦。此研究中製備了不同比例之BT/β-TCP結合膠原蛋白的多孔複合材料。而後通過X射

線繞射（XRD）分析晶體結構，利用掃描電子顯微鏡研究微結構和形貌；藉由壓汞測孔儀測量孔隙率及孔洞大小；萬能試驗機測量其機械性質；毛細作用測試其對液體吸附速率。生物相容性測試則使用ISO10993-5之濃度標準進行細胞存活率分析(MTT assay)。結果顯示噴霧乾燥法造粒之45wt%BT/ 45wt%ꞵ-TCP/ 10wt%collagen複合材料有較佳的性質穩定性，其孔隙率為85.25%，機械強度3.19±0.41 MPa，28天之生物降解量為8.69±0.40wt%，生物相容性之細胞存活率達99.86±2.17%，並且在毛細作用測試有相對快速的液體吸附速率表現，有助於臨床應用上快速吸附並穩
