Background: Most loci associated with type 2 diabetes mellitus (T2DM) discovered to date are within noncoding regions of unknown functional significance. By contrast, exonic regions have advantages for biological interpretation. Methods: We analyzed the association of exome array data from 14,026 Koreans to identify susceptible exonic loci for T2DM. We used genotype information of 50,543 variants using the Illumina exome array platform. Results: In total, 7 loci were significant with a Bonferroni adjusted P=1.03×10–6. rs2233580 in paired box gene 4 (PAX4) showed the highest odds ratio of 1.48 (P=1.60×10−10). rs11960799 in membrane associated ring-CH-type finger 3 (MARCH3) and rs75680863 in transcobalamin 2 (TCN2) were newly identified loci. When we built a model to predict the incidence of diabetes with the 7 loci and clinical variables, area under the curve (AUC) of the model improved significantly (AUC=0.72, P<0.05), but marginally in its magnitude, compared with the model using clinical variables (AUC=0.71, P<0.05). When we divided the entire population into three groups—normal body mass index (BMI; <25 kg/m2), overweight (25≤ BMI <30 kg/m2), and obese (BMI ≥30 kg/m2) individuals—the predictive performance of the 7 loci was greatest in the group of obese individuals, where the net reclassification improvement was highly significant (0.51; P=8.00×10–5). Conclusion: We found exonic loci having a susceptibility for T2DM. We found that such genetic information is advantageous for predicting T2DM in a subgroup of obese individuals.

본 연구의 목적은 e-포트폴리오를 작성하고 제작한 대학생이 무엇을 경험하고 있는지를 질적으로 탐색하는 데 있다. 구체적으로 e-포트폴리오의 제작 동기, 성과, 그리고 활용 차원에서의 의미를 살펴보았다. 이를 통해 본 연구는 e-포트폴리오가 대학생의 진로 및 경력 개발에 어떠한 의미를 지니고 있는지를 관찰하고자 하였다. 이러한 연구 목적을 달성하기 위하여 충북 소재 A 대학의 재학생 8명을 대상으로 심층 면담을 실시하였다. 이들은 A 대학에서 개최한 ‘e-포트폴리오 경진대회’에 참여한 학생으로서, e-포트폴리오 제작 경험에 대해서 심층적인 정보 전달이 가능하다. 연구 결과, 제작 동기로는 1) 대학 생활 및 경험에 대한 정리 기회, 2) 진로 준비에 도움, 제작 성과로는 1) 성찰 활동을 통한 자기 이해, 2) 진로 확신, 3) 대학 이해 및 소속감 제고, 활용 측면에서의 의미로는 1) 자기 표현의 수단, 2) 경험 공유의 수단이 도출되었다. 연구 결과를 토대로 대학 차원에서 학생의 대학 생활을 체계적으로 관리, 활용하는 전략을 수립하는 데 시사점을 제언하였다. The purpose of this study is to qualitatively explore the experience of college students who have created e-portfolio, specifically examining the motivations and achievements. Moreover, the significance of e-portfolio in students' career and professional development was observed. To achieve the objective, in-depth interviews were conducted with eight enrolled students at A University. These students had participated in the "E-Portfolio Competition" held at A University, and thus were able to provide detailed information about their experience in developing e-portfolio. The findings revealed that the motivations for e-portfolio development were: 1) summarizing university life and experience, and 2) seeking assistance for career development. The achievements of e-portfolio development were identified as: 1) self-understanding through reflection, 2) career certainty, and 3) enhanced understanding and affiliation with the university. As for the significance of e-portfolios application, it was found to be: 1) a means of self-expression, and 2) a platform for sharing experience. Based on the results, implications were discussed to establish strategies at the university level to systematically manage and utilize students’ university life.
