PURPOSE: Patient-centred care can increase patient satisfaction and lead to better clinical outcomes for them, such as improved physical status and higher health-related quality of life. However, doctors' and patients' views on patient-centred attitude might differ and could be affected by culture and the community environment. To clarify the differences in primary care patients' and senior medical students' perceptions of medical students' patient-centred attitude. METHODS: A total of 1,025 subjects-827 patients from primary care institutions and 198 fourth-year medical students from a medical college in South Korea-completed the Patient Practitioner Orientation Scale (PPOS). The students completed the self-reported questionnaire at the end of their clinical clerkship. Descriptive statistics, t-tests, and one-way analysis of variances were conducted in SPSS version 21.0. RESULTS: Firstly, sharing subscale scores were higher among patients than among medical students (students, 3.61 vs. patients, 3.76; p<0.001), but secondly, caring subscale scores were higher among medical students (students, 4.18 vs. patients, 3.82; p<0.001). Thirdly, PPOS total scores were higher among medical students (students, 3.90 vs. patients, 3.79; p=0.001). Finally, male students had the lowest sharing scores (F=6.811, p<0.001) and female students showed the highest PPOS total scores (F=5.805, p=0.001). CONCLUSION: Significant differences between medical students' and patients' perceptions of medical students' patient-centred attitudes suggest the necessity of educational efforts to overcome the gap between the groups.

PURPOSE: Communication skills are essential skills which medical students need to acquire in order to become a doctor. More attention is being given to the subject but not many studies have been done in the medical education field. As communication skills are provided to students as a subject in medical educational curriculum, the assessment of its effectiveness needs to be undertaken. METHODS: In the year 2005 and 2006, second year pre-medical students at The Catholic University College of Medicine took 'Communication Skills' course in total, 180 second year pre-medical students' survey results were used in the evaluation of the study question. The instrument used in the study was the modified and translated version of 'Beyer-Fetzer's Essential Elements of Communication Skills Assessment Sheet.' The assessment sheets were used as the pre-test and post-test to analyse the differences, which were put through the paired t-test. RESULTS: All categories of communication skills showed an improvement. For year 2005, meaningful differences were shown in 'opening the discussion (p=.005)' and 'sharing information (p=.008)', whereas in 2006, improvements were shown in all areas. CONCLUSION: From the result, it is clear that in order to create an effective communication skills program, the content should be more structured and focused on the program objectives.

PURPOSE: This study aims to examine the satisfaction of undergraduate medical students with their medical professionalism education. METHODS: Two hundred and one premedical students and 1,287 medical students (from year 1 to 4) participated in a five-point Likert scale survey. There were 27 items in the premedical students' survey and 31 items in the medical students' questionnaire. Statistical analysis including one-way ANOVA was performed. RESULTS: Among the 27 items concerning premedical professionalism education, only six topics scored "average" level. In the survey of medical students only nine items out of 31 were rated "average" which did not reach the satisfactory level. Nine items from the medical students' survey showed significant positive improvements in satisfaction as the academic year increased; however, the changes were not large enough for any of the topics to receive a satisfactory score. CONCLUSION: Overall students were dissatisfied with their professionalism education. The reasons for these results and possible approaches for improving students' satisfaction should be considered in future research.

PURPOSE: We aimed to investigate whether airway parameters, assessed via computed tomography (CT), are associated with abdominal fat areas and to compare the clinical characteristics of asthmatic patients with and without elevated visceral to subcutaneous fat area ratio (EV). METHODS: Asthmatic patients (aged ≥40 years) were prospectively recruited. Chest (airway) and fat areas were assessed via CT. Airway parameters, including bronchial wall thickness (WT), lumen diameter (LD), lumen area (LA), wall area (WA), total area (TA), as well as WA/TA percentage (wall area %) were measured at the apical segmental bronchus in the right upper lobe. Visceral (VFA), subcutaneous (SFA) and total (TFA) fat areas (cm2) were also measured. The correlations between abdominal fat areas and airway parameters were assessed. EV was defined as VFA/SFA ≥ 0.4. RESULTS: Fifty asthmatic patients were included (mean age 62.9 years; 52% female); 38% had severe asthma. Significant correlations were found between VFA and both LD and LA (r = −0.35, P = 0.01; r = −0.34, P = 0.02, respectively), and SFA and both WA and TA (r = 0.38, P = 0.007; r = 0.34, P = 0.02, respectively). Exacerbations, requiring corticosteroid therapy or ER visitation, were significantly more frequent in subjects without EV (83% vs. 34%, P = 0.05). CONCLUSIONS: Abdominal fat is associated with asthma, according to the location of fat accumulation. In asthmatic subjects, visceral fat seems to be attributable to the bronchial luminal narrowing, while subcutaneous fat may be related to thickening of bronchial wall.

PURPOSE: From 2009, the Korean Medical Licensure Exam implemented a clinical performance examination (CPX) that highlighted the importance of good patient-physician relationships in medical education. This study aimed to examine changes in medical students' attitudes before and after implementation of the CPX in their medical education curriculum. METHODS: In 2006 and 2009, 236 fourth-year medial students of C College of Medicine took the Patient Practitioner Orientation Scale (PPOS) by Krupet et al. (2000), which measures patient-centered attitudes in patient-physician relationships. The data were analyzed by independent t-test and two-way analysis of variance using SPSS 21.0. RESULTS: The PPOS scores of year 2006 students were 3.88+/-0.25 for males and 3.98+/-0.38 for females. For year 2009 students, males scored 3.81+/-0.42 and females scored 4.01+/-0.48. All students had higher Care scores than Share scores (2006: Share, 3.67+/-0.47 vs. Care, 4.19+/-0.51; 2009: Share, 3.56+/-0.34 vs. Care, 4.18+/-0.53). There were significant differences in PPOS and Share scores by gender before and after the CPX. With regard to Care scores, female students' scores tended to rise and males' scores declined over time. CONCLUSION: An educational program is needed for students to foster patient-centered attitudes, but gender differences should be taken into account.

Since the early 2000s, there has been a continued interest in lie detection using functional magnetic resonance imaging (fMRI) in neuroscience and forensic sciences, as well as in newly emerging fields including neuroethics and neurolaw. Related fMRI studies have revealed converging evidence that brain regions including the prefrontal cortex, anterior cingulate cortex, parietal cortex, and anterior insula are associated with deceptive behavior. However, fMRI-based lie detection has thus far not been generally accepted as evidence in court, as methodological shortcomings, generalizability issues, and ethical and legal concerns are yet to be resolved. In the present review, we aim to illustrate these achievements and limitations of fMRI-based lie detection.

The role of glutamatergic system in the neurobiology of mood disorders draws increasing attention, as disturbance of this system is consistently implicated in mood disorders including major depressive disorder and bipolar disorder. Thus, the glutamate hypothesis of mood disorders is expected to complement and improve the prevailing monoamine hypothesis, and may indicate novel therapeutic targets. Since the contribution of astrocytes is found to be crucial not only in the modulation of the glutamatergic system but also in the maintenance of brain energy metabolism, alterations in the astrocytic function and neuroenergetic environment are suggested as the potential neurobiological underpinnings of mood disorders. In the present review, the evidence of glutamatergic abnormalities in mood disorders based on postmortem and magnetic resonance spectroscopy (MRS) studies is presented, and disrupted energy metabolism involving astrocytic dysfunction is proposed as the underlying mechanism linking altered energy metabolism, perturbations in the glutamatergic system, and pathogenesis of mood disorders.

PURPOSE: Although there are over 40,000 licensed radiological technologists (RTs) in Korea, job competency standards have yet to be defined. This study aims to clarify the job competency of Korean RTs. METHODS: A task force team of 11 professional RTs were recruited in order to analyze the job competency of domestic and international RTs. A draft for the job competency of Korean RTs was prepared. A survey was then conducted sampling RTs and the attitudes of their competencies were recorded from May 21 to July 30, 2016. RESULTS: We identified five modules of professionalism, patient management, health and safety, operation of equipment, and procedure management and 131 detailed job competencies for RTs in Korea. “Health and safety” had the highest average score and “professionalism” had the lowest average score for both job performance and importance. The content validity ratios for the 131 subcompetencies were mostly valid. CONCLUSION: Establishment of standard guidelines for RT job competency for multidisciplinary healthcare at medical institutions may be possible based on our results, which will help educators of RT training institutions to clarify their training and education.

As the prevalence and life expectancy of type 2 diabetes mellitus (T2DM) continue to increase, the importance of effective detection and intervention for the complications of T2DM, especially neurocognitive complications including cognitive dysfunction and dementia, is receiving greater attention. T2DM is thought to influence cognitive function through an as yet unclear mechanism that involves multiple factors such as hyperglycemia, hypoglycemia, and vascular disease. Recent developments in neuroimaging methods have led to the identification of potential neural correlates of T2DM-related neurocognitive changes, which extend from structural to functional and metabolite alterations in the brain. The evidence indicates various changes in the T2DM brain, including global and regional atrophy, white matter hyperintensity, altered functional connectivity, and changes in neurometabolite levels. Continued neuroimaging research is expected to further elucidate the underpinnings of cognitive decline in T2DM and allow better diagnosis and treatment of the condition.

OBJECTIVES: The aim of this study was to assess variations in caudate volume according to dopamin receptor D2/ankyin repeat and kinase domain containing 1 (DRD2/ANKK1) Taq 1a polymorphisms in young healthy adults and to evaluate the relationship between caudate volumes and psychiatric symptoms as measured by the Brief Psychiatric Rating Scale. METHODS: Genetic information regarding DRD2/ANKK1 Taq 1a and T1-weighted brain magnetic resonance images were acquired from 30 young healthy adults. Automatic segmentation of caudate was performed using the FreeSurfer program. RESULTS: Individuals with A2 homozygotes of DRD2/ANKK1 Taq 1a polymorphisms (n = 10) had greater right caudate volumes compared to those with A1 allele (s)(18.4% greater ; p = 0.019). Right caudate volumes were negatively associated with total scores of the Brief Psychiatric Rating Scale (beta=-0.50 ; p = 0.016). CONCLUSIONS: Our findings suggest the possibility that DRD2/ANKK1 Taq 1a polymorphisms may underlie the psychiatric symptoms by influencing the structure of the right caudate.
