日治初期嘉義當地在現代醫學的建置上，長期扮演殖民體制下醫療政策的被動執行者。隨著政府培育的臺籍醫師員額逐漸成長，當地於 1927 年出現了僅由臺人組成的醫事專業團體「嘉義醫會」，並脫離由日人主導的前醫會。獨立後的嘉義醫會在 1934 年至 1939 年間發行了《嘉義醫會醫學雜誌》，在當時是本島唯一以地方為刊名的醫學專業期刊。該雜誌的特殊之處，在於除了刊載醫學論文，也包括漢詩、時事評論及生活雜文等，記錄下嘉義的臺人醫師們在殖民情境變動下的心境。本文將透過相關文獻及該期刊的書寫紀錄，探討他們如何透過雜誌文章的書寫，中介殖民現代性下兼具傳統與現代，並且隨殖民進程變化的臺人醫師身分。 透過對《嘉義醫會醫學雜誌》的考察，本文以傳媒實踐作為分析視角，來理解殖民社會中各種文化互動和影響。發現臺人醫師社群在專業組織的進程中， 含括了當時的醫學技術網絡，也匯聚了地方上的不同家族、漢詩社以及臺灣文化協會等各種社會網絡。在其各種社會實踐的互動當中，體現其複合及多元的社會身分，並展現出其認同策略的彈性。突顯了《嘉義醫會醫學雜誌》作為一種特殊而重要的地方性和民族性媒介，在殖民主義下如何扮演連結不同社會層面和意識形態的角色。並且揭示了《嘉義醫會醫學雜誌》在形塑嘉義地域認同上所發揮的作用，以及其與全國性期刊之間存在的差異和聯結。 

 During the early period of Japanese rule, Chiayi played a passive role in implementing medical policies under colonialism in the establishment of modern medicine. As the number of Taiwanese doctors trained by the government gradually increased, a professional group called "Chiayi Medical Association" consisting solely of Taiwanese was established in 1927 and separated from the former medical association led by Japanese. After independence, Chiayi Medical Association published "Chiayi Medical Journal" from 1934 to 1939, which was the only local medical professional journal on this island at that time. The uniqueness of this journal lies not only in publishing medical papers but also including Chinese poetry, current affairs commentary and miscellaneous essays to record how Taiwanese doctors in Chiayi felt under changing colonial circumstances. This article will explore how they used their writing through magazine articles as an intermediary between traditional and modernity under colonial modernity while adapting to changes during their identity as Taiwanese doctors with relevant literature and written records from that periodical. Through an examination of the Chiayi Medical Association Journal, this article uses media practice as an analytical perspective to understand various cultural interactions and influences in colonial society. It was found that the Taiwanese physician community included various social networks such as local families, Han poetry societies, and the Taiwan Cultural Association in their professional organization process, which also encompassed medical technology networks at that time. In their interaction with various social practices, they embodied their complex and diverse social identities and demonstrated flexibility in their identity strategies. The Chiayi Medical Association Journal is highlighted as a special and important local and ethnic medium that plays a role in connecting different social levels and ideologies under colonialism. It also reveals the role played by the journal in shaping Chiayi's regional identity, as well as differences and connections between it and national journals.
