政府在傳達政令時需藉由宣導訊息與民眾溝通，而訊息設計必須考量不同訴求、結構和表現的搭配，來呈現不同的宣導內容。本研究目的有三：1.不同年代的交通安全宣導廣告訊息內容表現之差異。2.不同主題的交通安全宣導廣告訊息內容表現之差異。3.目標閱聽眾（target audience）對於交通安全宣導節目訊息的認知效果。 本研究以內容分析法與焦點團體訪談（FGD）進行交通安全宣導廣告與電視節目個案研究，研究結果發現： （一）訊息訴求的運用：年代、主題不同與訊息訴求方式無關。（二）訊息結構的運用：年代早期傾向運用正反面訊息並陳的「雙面訊息」來呈現廣告內容，而近期較多單獨使用正面或反面訊息的「單面訊息」廣告。（三）訊息表現的運用：不同年代在「語言」、「音樂」、「旁白」、「配音人員效果」、「場景」和「演出人物人數」的運用上有顯著差異；而不同主題在「場景」和「演出人物人數」的運用上有顯著差異。（四）「劇情式」節目比「趣味競賽式」節目具有較佳的宣導效果。

本文旨在探討政府公關對記者間日常互動與危機運作，雖以政府公關為研究角度，然互動過程是你來我往的動態過程，不應只從單一面向研究，必須知曉雙方的立場與看法，才能較宏觀瞭解消息來源與記者兩者互動的情形。鑑於過去研究不是單從消息來源就是從記者角度出發，本研究以政府公關與記者為研究對象，探討政府公關日常對記者的互動關係與行為模式，而這些關係在危機時是否能為政府公關所用。 本研究以政府公關與記者的互動為分析資料，探討四個面向：第一，政府公關如何與記者互動，並且管理維繫雙方善意的關係；第二，政府公關影響新聞產製的方式；第三，政府公關與記者之間關係如何轉化為人脈、人情與信任而為之所用；第四，政府公關對記者日常互動往來，當政府公關面臨危機運作產生的效用或影響。 本研究採用深度訪談法，訪問政府公關與記者各三位，從中歸納出政府公關對記者的日常互動與危機運作，包括「政府公關與記者互動影響因素」、「政府公關操縱新聞產製」、「政府公關運用人際關係」以及政府公關面臨危機個案之運用。 / This study aims to analyze interactions of government public relations officers with journalists and crisis management. Although this study takes the viewpoints from the government public relations officers, as the interaction is a two-way dynamic communication process, we should examine the positions and perspectives of both parties so as to understand the real situations between them in a macroscopic method. Since the past studies take viewpoints from either sources or journalists, this study takes both government public relations officers and journalists as study objects, and discusses their behavior to see if the government public relations officers are able to utilize the relationships when crises take place. The study includes four aspects: (1) How government public relations officers interact with journalists and manage to maintain a fine relationship. (2) How government public relations officers affect the news production. (3) How the relationship between both sides converts into personal connections, sympathy and trust, which then can be utilized. (4) How the daily interactions benefit or impact crisis management of the government public relations officers. This study employs in-depth interview as the study method. The interviewees are three government public relations officers and three journalists. The study results indicate that the daily interactions between the two sides and crisis management can be divided into four parts: “the necessary elements of the interactions between government public relations officers and journalists”, “government public relations officers’ manipulation of news production”, “government public relations officers’ utilization of interpersonal connections”, and “the government public relations officers’ utilization of relationships when crises arise”.
