Purpose: This study explores the association between student involvement in non-academic activities (NAA) and the stages of professional identity formation (PIF) among Indonesian medical students. Methods: This cross-sectional survey was distributed to students in 50 medical schools, across both preclinical and clinical students in years 2-6. Respondents completed a Developmental Scale (DS) questionnaire to assess PIF and self-reported the number of hours spent on different NAA. Descriptive and bivariate analyses were performed; multiple linear regression was utilized to predict PIF. Results: Indonesian medical students reported a median of 13 NAA hours and a median DS score of 5.07 on a scale of 7. NAA hours were significantly different across sex groups, years of study, university regions, and institution types. Female participants spent significantly more hours on NAA than male students and PIF was predicted by the number of hours spent on research and competition-related activities. Shifts between the types of NAA were also observed among year groups. Conclusion NAA are positively associated with the PIF process, with students’ active involvement in research and competitionrelated activities as predictors in this area. Supporting these activities becomes imperative for medical schools in order to optimize students’ potential, motivation, and PIF.

OBJECTIVE: Considering the different prevalence rates of diseases such as asthma and chronic obstructive pulmonary disease in Asians relative to other races, Koreans may have unique airway structure and lung function. This study aimed to investigate unique features of airway structure and lung function based on quantitative computed tomography (QCT)-imaging metrics in the Korean Asian population (Koreans) as compared with the White American population (Whites). MATERIALS AND METHODS: QCT data of healthy non-smokers (223 Koreans vs. 70 Whites) were collected, including QCT structural variables of wall thickness (WT) and hydraulic diameter (Dh) and functional variables of air volume, total air volume change in the lung (ΔVair), percent emphysema-like lung (Emph%), and percent functional small airway disease-like lung (fSAD%). Mann-Whitney U tests were performed to compare the two groups. RESULTS: As compared with Whites, Koreans had smaller volume at inspiration, ΔVair between inspiration and expiration (p < 0.001), and Emph% at inspiration (p < 0.001). Especially, Korean females had a decrease of ΔVair in the lower lobes (p < 0.001), associated with fSAD% at the lower lobes (p < 0.05). In addition, Koreans had smaller Dh and WT of the trachea (both, p < 0.05), correlated with the forced expiratory volume in 1 second (R = 0.49, 0.39; all p < 0.001) and forced vital capacity (R = 0.55, 0.45; all p < 0.001). CONCLUSION: Koreans had unique features of airway structure and lung function as compared with Whites, and the difference was clearer in female individuals. Discriminating structural and functional features between Koreans and Whites enables exploration of inter-racial differences of pulmonary disease in terms of severity, distribution, and phenotype.
