[Purpose] This study investigated the primary factors behind changes in depressive symptoms among stroke patients after 8 weeks of rehabilitation (physical, occupational, and cognitive therapy). [Methods] This study was conducted using a literature review, and electronic medical records from January, 2008 to December, 2009. Data were collected for 120 subjects with chronic stroke. [Results] Cardiac disorder, left-brain lesion, early-stage depression, activities of daily living, and cognitive function were significant predictors of the changes in depression in chronic stroke patients. [Conclusion] Post-stroke depression can be controlled by rehabilitation. Also, clinicians should comprehend and share the psychological and physical affliction, develop back-up programs, and make them comprehensively available to support the psychological and physical health of subjects with chronic stroke.

Sudden unexpected deaths due to cardiovascular diseases make up almost half of all natural deaths. Practical guidelines are needed for forensic autopsy practice in cases of natural unexpected deaths due to ischemic heart disease or other cardiovascular diseases in Korea. An evaluation of the clinical history is the first step, including the collection of all available information on the subject. As a standard autopsy procedure, every subsystem of the heart and vessels should be thoroughly studied including the coronary arteries, the myocardium, the cardiac valves, and the conducting system. In addition, histological, toxicological, biochemical and molecular analysis need to be applied to the detection of myocardial infarction from the medico‐legal point of view. Also important is the assessment of risk factors for natural unexpected cardiac death (NUCD) in order to establish a cause–effect relationship. There are three groups of ischemic conditions of heart leading to NUCD, those being acute myocardial infarction, atherosclerotic heart disease and critical coronary atherosclerosis. Additionally, there are practical concerns on formulating the report. Pathologists may use sudden cardiac death or NUCD as a main diagnosis when there is no alternative diagnosis, though they would do better to comment on conditions contributing to the death. Finally, pathologists should be encouraged to suspect unexplained causes of death in order to find clearer answers.

The concentration distributions of selected hazardous environmental factors in a museum environment were calculated by using the inverse variance weighted average in meta-analysis, and the concentration distributions possibly emerging in a museum exhibition halls and storages were computed through Monte Carlo simulation in order to minimize the uncertainty that can be caused from meagerness of related domestic researches.
