مقايسه متون فيزيولوژي گايتون و فارسي ويژه ي پزشكي: تحليلي پيكره-بنياد

Comparison of Guyton's Physiological Texts and Persian for Medical Purposes: A Corpus-based Analysis

بررسي و تحليل مقايسه اي متون آموزشي، ما را به درك دقيق تري از ويژگي ها ي آنها رهنمون مي سازد؛ در همين راستا، پژوهش حاضر درصدد پاسخگويي به اين پرسش است كه آيا اساساً تفاوتي بين متون ويژه ي علوم پزشكي دوره ي تكميلي فارسي آموزان غيرايراني و متون پزشكي ترم نخست دوره ي دانشگاهي از نظر موضوعات استعاره ي دستوري، اجزاي مرتبه بندي شده و واژگون مرتبه در سطح بند و بند مركب وجود دارد يا خير؟ در انجام پژوهش، پيكره اي مشتمل بر 9886 واژهي مستخرج از متون كتاب فارسي ويژهي علوم پزشكي براي دانشجويان خارجي و 9775 واژه از متون كتاب فيزيولوژي گايتون تهيه شده است. سپس، هر يك از ويژگي هاي زباني مورد نظر، به صورت جداگانه، در چارچوب دستور نظام مند-نقش گراي هليدي، شناسايي و استخراج شده و سپس با استفاده از نرم افزارهاي مناسب، داده ها جمع آوري، دسته بندي و خلاصه شده است. نتايج پژوهش، فرضيه ي پژوهش مبني بر وجود تفاوت قابل توجه بين متون ويژه ي علوم پزشكي دوره ي تكميلي فارسي آموزان غيرايراني و متون پزشكي ترم نخست دوره ي دانشگاهي را مورد تاييد قرار ميدهد. همچنين، بررسي و تحليل ويژگي هاي جزئي تر پيكره نشان داد كه در مجموع شباهت هايي بين دو بخش پيكره در ويژگي هايي همچون مرتبگي، واژگون مرتبگي و استعاره ي دستوريِ انديشگاني وجود دارد اما در جزئياتي همچون ترتيب واژگون مرتبگي بي زمان و تعداد الگوهاي آن و نيز سلسله مراتب روابط منطقي-معنايي بين بندهاي وابسته، تفاوت هايي به چشم مي خورد. به نظر مي رسد عوامل مورد بررسي در اين پژوهش مي تواند براي بررسي وجوه اشتراك و افتراق متون مختلف مورد استفاده قرار گيرد

Comparative study and analysis of educational texts leads us to a more accurate understanding of their characteristics. In this regard, the present study aims to answer the question that whether there are the differences between the textbooks which are specially designed for the non-Iranian Persian learners in advanced courses and those medical texts which are taught at the first semester of the academic year. Doing so, the texts were analyzed and compared with regard to the grammatical metaphor, ranked and rank-shifted components at the level of the clause and clause complex, and so on. In the course of the research, a corpus consisting of 9886 words extracted from the textbooks of the of medical sciences texts for Persian learners and 9775 words from the Guyton's physiology texts were selected and analyzed. Then, each of the linguistic features was individually identified and extracted in the framework of systemic-functional grammar of Halliday. Afterwards, using appropriate software, data were collected, categorized and summarized. The research results confirmed the hypothesis of the research stating that there was a significant difference between the texts of medical sciences for Persian learners and the medical texts for the first semester of the academic year. In addition, the in-depth analysis showed that, in general, there were similarities between the two parts of the structure with regards to characteristics such as ranking, rank-shifting, and ideational grammatical metaphor. In addition, there existed some differences between the order of non-finite rank-shifting and the number of patterns as well as in the logical-semantic relations between the dependent clauses. It seems that the factors of the research can be used to examine the various aspects of similarities and differences of various texts.
