Under the Radar: Tracking Western Radio Listeners in the Soviet Union
為了解決Shortwave radio 的問題，作者Parta, R. Eugene 這樣論述：
Western democracy is currently under attack by a resurgent Russia, weaponizing new technologies and social media. How to respond? During the Cold War, the West fought off similar Soviet propaganda assaults with shortwave radio broadcasts. Founded in 1949, the US-funded Radio Free Europe/Radio Lib
erty broadcast uncensored information to the Soviet republics in their own languages. About one-third of Soviet urban adults listened to Western radio. The broadcasts played a key role in ending the Cold War and eroding the communist empire.R. Eugene Parta was for many years the director of Soviet A
rea Audience Research at RFE/RL, charged among others with gathering listener feedback. In this book he relates a remarkable Cold War operation to assess the impact of Western radio broadcasts on Soviet listeners by using a novel survey research approach. Given the impossibility of interviewing Sovi
et citizens in their own country, it pioneered audacious interview methods in order to fly under the radar and talk to Soviets traveling abroad, ultimately creating a database of 51,000 interviews which offered unparalleled insights into the media habits and mindset of the Soviet public. By recounti
ng how the impossible mission was carried out, Under the Radar also shows how the lessons of the past can help counter the threat from a once and current adversary.
以稀土元素摻雜之奈米粒子用於黑色素瘤的放射治療
為了解決Shortwave radio 的問題，作者蕭心柔 這樣論述：
以稀土元素摻雜之奈米粒子(rare-earth-doped nanoparticles, RENPs)具有優異的光學特性，過去作為上轉換奈米粒子(upconversion nanoparticles)而快速發展生物醫學應用，近年來逐漸有文獻指出RENPs可作為診療雙用途奈米粒子(theranostic nanoparticles)的潛力，RENPs不僅在X 射線照射時提供放射增敏劑(radiosensitizer)的功能，還具有第二近紅外區(second near infrared, NIR-II)的光學成像(imaging)特性。由於RENPs具有高化學穩定性及低毒性之優點，本研究試圖運用
X射線合併RENPs用於治療黑色素細胞瘤。在製備方法上，吾人使用油酸為介面活性劑以合成疏水性之RENPs，為了使該種奈米粒子能夠應用於生醫領域，本研究比較了兩種對該奈米粒子進行的表面修飾(surface modification)，包含了：(1)表面修飾二氧化矽，(2)使用聚山梨醇酯20 (TWEEN@ 20)作為表面穩定劑的RENPs。研究結果顯示，Tween 20-RENPs奈米粒子在水溶液中表現出優異的光學特性，並且沒有任何形態轉變。使用黑色素瘤細胞株(B16F10 Red-FLuc)，證明了Tween 20-RENPs的細胞毒性極低(IC50>1000 μg/mL)，並且在給予放射劑量
2 Gy(X射線)時，有合併使用RENPs(800 μL)時確實呈現放射增敏現象(∗∗p=0.0082; unpaired t test; two-tailed)。運用負荷惡性黑色素瘤的動物，對於較小體積的黑色素腫瘤(80~100 mm3)，單獨使用放射治療可以抑制腫瘤生長，其中4 Gy放射治療劑量在連續兩天內投予(4 Gy in 2 Gy daily)放射治療相較於4 Gy放射治療劑量間隔七天投予(4 Gy in 2 Gy weekly)效果更好；對於較大體積的黑色素腫瘤(150~200 mm3)，單獨使用放射治療無法有效抑制腫瘤，而合併RENPs可以做為放射增敏劑在X射線放射劑量為4 Gy
在連續兩天內投予(4 Gy in 2 Gy daily)時，抑制腫瘤成長。綜合上述的觀察，本研究證明以稀土元素摻雜之奈米粒子可以應用作為 X 射線治療皮膚惡性黑色素瘤的放射增敏劑之可行性。
Dial Dancing: Tales of the the Fascinating, Fabulous, Frequency-hopping, Wavelength-Walking, Power Punching, Ionosphere-Scorchin
為了解決Shortwave radio 的問題，作者Keith, Don 這樣論述：
Amateur or ham radio is more alive, more vibrant, more exciting and magical than ever. Now award-winning and best-selling author Don Keith, who is an active and enthusiastic amateur radio operator, spins a series of tales that show exactly what this amazing hobby offers. Help save lives with emergen
cy communications and weather spotting. Compete in radiosport. Talk with friends all over the planet, bouncing signals off the ionosphere, through ham radio satellites in orbit, or even using the tail of a comet, the moon, or the Northern Lights. Bring radio to mountaintops, remote islands, or natio
nal parks. And do it all with a station you helped put together. Now, with these exciting, emotional, funny and captivating tales, you can learn about the magic of amateur radio and how you can begin dancing around the dial. Don Keith is an award-winning broadcaster, a best-selling author, and has
been a licensed amateur radio operator since 1961. He was first licensed as WN4BDW in 1961, earned his General class license later that year, and then became an Amateur Extra class licensee in the mid-1970s, changing the call sign then to N4KC. He was twice named Billboard Magazine’s ＂Broadcast Per
sonality of the Year,＂ won every major broadcast journalism award in his state from the Associated Press and United Press International, and was an on-air personality, journalist, station owner, program director, and manager in a broadcasting career that spanned over two decades. Don published his f
irst novel, The Forever Season, in 1995. It has remained in print continuously since and was named ＂Fiction of the Year＂ by the Alabama Library Association. His more than two dozen other published works, fiction and non-fiction, cover such topics as NASCAR racing, broadcasting, college sports, subma
rines, biography, and World War II history. His submarine-thriller novel, Firing Point, will be a major motion picture starring Gerard Butler and Gary Oldman, released under the title Hunter Killer. His non-fiction book on the historic voyage to the North Pole of America’s first nuclear submarine, U
SS Nautilus, in 1958 was titled The Ice Diaries and was submitted for consideration for the Pulitzer Prize. For the fiftieth anniversary of the under-ice mission, Don headed up an amateur radio special operating event from Historic Ship Nautilus in Groton, Connecticut. Don lives in Indian Springs Vi
llage, Alabama, with his wife, Charlene. They have three grown children, and four grandchildren. Don operates all the shortwave amateur radio bands as well as VHF and uses most modes, including CW, SSB, PSK31 and FM. He enjoys DXing, contesting, antenna experimenting, and just plain rag-chewing.

以科技接受模式探討廣播新媒體對受眾之影響—以國際短波廣播良友電台為例
為了解決Shortwave radio 的問題，作者任家慧 這樣論述：
傳統廣播媒體隨著新的時代科技進步，進入了一個新的領域，聲音隨著不同媒體的承載，也以不同的新面貌與受眾互動交流，除了過往的單純聲音呈現之外，又可以在各樣的網路、社群中，加以圖像、影片輔助，對於受眾、電台及主持人彼此間拓展了更大的可能性，在媒體轉換的過程當中，有很多的機會，卻也冒著相當的風險，需要更多準確的資訊，投注金錢、時間、人力、資源才有更好的回饋及收益。以運作七十多年的國際遠東短波中文廣播為例研究，這傳統的良友電台該如何換裝，以嶄新的樣態在受眾面前再次展現，吸引更多的注意，同樣也是每個傳統廣播媒體的大挑戰。本研究宗旨是以科技接受模式來探討廣播新媒體對於受眾收聽及與電台主持人互動之影響，透過
不同的科技媒體媒介，是否能增加廣播收聽率或媒體觸及率？透過問卷調查法，隨機抽樣對象以收聽過良友電台新媒體平台的受眾為主，量化分析，問卷發放共回收508份有效問卷，問卷樣本女性佔整體樣本的70.08%，男性佔整體樣本的29.92 %。研究中以三個構面為主，分別是同伴影響、社群及擬社會互動，分別對應認知易用性、認知有用性、使用態度及使用意願，交叉研究彼此是否有正相關。經由量化分析整理資料的結論顯示，因電台本身及節目宗教色彩鮮明，數據中歸納顯示，性別、年齡、身份、教育程度、職業，都決定了良友新媒體成為受眾收聽方式的重要選項，收聽對象主要以信徒居多；另外，良友新媒體的使用狀況，數據展現以新受眾群居多，
因新的受眾群可以藉由不同的平台接觸到良友電台的節目；再者，本研究透過科技接受模式來驗證認知易用性、認知有用性與影響態度、行為意願與三個構面之間的相互關係，量化分析後皆是正向關連性，研究證明同伴影響、社群、擬社會互動都會影響到受眾對於新媒體平台的收聽及與電台、主持人的互動交流。
