Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators will study in the possibility of cardiovascular disease, caused by the duty loading, of physician of internal medicine. The investigators will also explore if there {dose response effect} between the duty loading and the stress response of physicians of internal medicine. Therefore, the investigators will compare the stress responses of physicians of internal medicine during with different duty loading ( non-duty day, one duty area with 3 wards, 2 duty areas with 6 wards) in a observational method. Those stress response will be measured by cardiovascular risk indicators, including blood pressure, heart rate variability, blood sampling and urine sampling.
