[Patient-centeredness of medical students during a real patient encounter and a standardized patient encounter on the clinical performance examination].

Purpose: Patient-centered care is one of the most important factors of high-quality medical care. Medical educators have been increasingly interested in education for patient-centered care. This study was conducted to guide such education by assessing the patient-centeredness of medical students in a real patient encounter and a standardized patient encounter on the clinical performance examination (CPX).

Bone Mineral Density and Food-frequency in Korean Adults: The 2008 and 2009 Korea National Health and Nutrition Examination Survey.

Background: Diet and Nutrition are important modulators of bone health in men and women. We investigated the associations between frequency of food intake among certain food groups and bone mineral density (BMD) in a large population of Korean adults.

Methods: We used the data from Korea National Health and Nutrition Examination Survey during 2008 to 2009.

Relationship between Food-frequency and Glycated Hemoglobin in Korean Diabetics: Using Data from the 4th Korea National Health and Nutrition Examination Survey.

Background: This study was performed to evaluate the association between food intake frequencies and long-term blood glucose control using glycated hemoglobin (HbA1c) in Korean diabetes.

Methods: This study used data collected from the 4th Korea National Health and Nutrition Examination Survey. Patients with diabetes were defined as people who responded "yes" to the question "Are you currently suffering from diabetes?" or in whom serum fasting glucose was 126 mg/dL or more.

Diagnostic value of the rapid influenza antigen test for novel influenza A (H1N1).

We administered both the rapid antigen test and real-time reverse transcriptase polymerase chain reaction (RT-PCR) test to 2154 patients in order to assess the diagnostic value of the rapid antigen test during Korean pandemics of H1N1 2009. The overall sensitivity was 70.0%, specificity was 97.
