Theoretical and Practical Changes in L2 Teacher Education: A Critical Review
( Nihat Polat ) 순천향대학교 인문과학연구소 2008 순천향 인문과학논총 Vol.22 No.-
A considerable number of recent studies have suggested that paradigmatic historical changes and challenges in different aspects of L2 teacher education have resulted in the acknowledgement of its complex constituents and thereby the inclusion of more diachronic, holistic, multifaceted, eclectic, integrative and sometimes seemingly contentious approaches and conceptualizations. This critical review addresses the most recent changes and challenges in epistemological, theoretical, metho dological and practical aspects of L2 teacher education. It shows how researchers have taken different perspectives in categorizing and interpreting these perceptible transformations and challenges in L2 teacher education. Moreover, it addresses how several recent studies on L2 teacher education have pinpointed changes and challenges and how they have been translated into domains and competencies in second/foreign teacher education program requirements. A synthesis of these selected papers also delineates certain key themes that can help educators and researchers to better understand the future direction of second/foreign language education.

Background and Objectives: The etiopathogenesis of coronary artery ectasia (CAE) is not known completely. In most of the cases, CAE is associated with atherosclerosis; however, isolated CAE has a nonatherosclerotic mechanism. The association between atherosclerotic coronary artery disease and apelin has been examined in previous studies. However, the role of plasma apelin in isolated coronary artery ectasia has not been studied. In this study, we investigated the relationship between plasma apelin levels and isolated coronary artery ectasia. Subjects and Methods: The study population included a total of 54 patients. Twenty-six patients had isolated CAE (53.6±8.1 years); 28 patients with normal coronary arteries (51.6±8.8 years) and with similar risk factors and demographic characteristics served as the control group. Apelin levels were measured using an enzyme-linked immunoassay kit. Results: Apelin level in the CAE group was significantly lower (apelin=0.181±0.159 ng/mL) than that in the control group (apelin=0.646±0.578 ng/mL) (p=0.033). Glucose, creatinine, total cholesterol, triglyceride, low density lipoprotein cholesterol, and high density lipoprotein cholesterol levels were not significantly different between the two groups. Conclusion: In this study, we showed that patients with isolated CAE have decreased plasma apelin levels compared with the control group. Based on the data, a relationship between plasma apelin and isolated CAE was determined.
