OBJECTIVES: The aim of this study is to find the association between mothers' working hours and obesity of their children according to children's age and gender. METHODS: This study used data from the second and third year of KNHANES IV and the first year in KNHANES V (2008-2010). We calculate odds ratio (OR) and 95% confidence interval (CI) by using survey logistic regression to assess association of mother's working hours with overweight or obesity of her children. The model was adjusted with household income, mothers' education and obesity and mothers' job characteristics. RESULTS: 13-18 aged boys whose mothers worked under 40 hours per week were higher risk for obesity and overweight (including obesity) than 13-18 aged boys whose mothers worked 40-48 hours. 6-12 aged girls whose mothers worked 49-60 hours per week were more overweight (including obesity) than girls whose mothers worked 40-48 hours per week. 13-18 aged girls whose mothers worked over 60 hours were more overweight (including obesity) than the reference. CONCLUSION: This study showed that girls' obesity was associated with mothers' long working hours. Long working hours can influence health of workers' family.

Compressive asphyxia is generally defined as a type of asphyxia caused by chest or abdominal compression by a heavy object. It has also been reported that it could be caused by external compression caused by ligatures around the chest or abdomen. However, asphyxia caused by ligature around the thorax has not been reported in suicide cases. We present an unusual case of suicide in which the cause of death was attributed to asphyxia caused by a ligature around the thorax. The deceased was a 41-year-old woman who was found dead and suspended by a rope around the thorax from a rooftop railing on the twelfth floor of a building. On postmortem examination, a ‘C’ shaped ligature mark was identified around the thorax, with a pressure mark in the subcutis and focal intramuscular hemorrhages, which were consistent with the ligature mark. The cause of death was determined to be asphyxia due to external compression of the chest in a suspended position.

This case study highlights craniofacial identification technology (CFIT) as a complementary and translational tool for reconstruction of cranial gunshot wounds (GSWs) and presenting evidence beyond forensic identification. In forensic cases involving GSWs, a visual demonstration of the bullet trajectory can improve communication between forensic pathologists and non-medical judicial agencies and the court. Postmortem computed tomography (PMCT) images and autopsy images are essential medical evidence, providing a robust visual display of the GSW and its bullet trajectory. PMCT images are useful for identifying the precise projectile localization and characteristics of bone fractures. However, PMCT images may not adequately present soft tissue injuries well, and autopsy images can be unpleasant to non-medical professionals, making it difficult for them to understand such specialized scientific evidence. CFIT is a well-established scientific tool with which forensic experts in craniofacial identification can create more advanced reconstructed three-dimensional (3D) images based on both postmortem findings and PMCT data. Intracranial bullet trajectory can be shown simply and directly in reconstructed 3D cranial images. CFIT can serve as an adjunctive tool to overcome the limitations of both PMCT images and autopsy images, thereby facilitating better understanding of such specialized medical evidence by non-medical professionals. Here, we present two cases of head GSWs, in which CFIT was newly implemented to reconstruct the cranial GSW including bullet trajectory, for evidence presentation—expanding its traditional use in forensic identification. Therefore, CFIT can help provide better forensic medical services for non-medical professionals.

Objective: To expand the scope of the work performed by emergency medical service (EMS) providers, a 3-day education training course was implemented at the national level to organize and operate a special EMS unit consisting of level-1 EMS providers and nurses. We conducted an evaluation of the curriculum for EMS providers that completed the education course. Methods: From June 2019 to July 2020, a survey was conducted to evaluate the curriculum of 270 EMS providers that completed the training course in Gangwon province. We analyzed differences between educational needs, satisfaction with educational contents, and job performance confidence with respect to age, sex, certification, and career. Results: We analyzed the contents of 143 questionnaires received from the EMS providers. Satisfaction with the “instructor” was highest at 4.52 points, and satisfaction with the “education” provided was lowest at 3.89 points. Those aged over 40 had the highest satisfaction scores for “education”, and a significant inverse relationship was found between age and satisfaction (P=0.020). In the overall curriculum, educational need was highest among those with a career duration of ≥ 3 years and those in their 30s. Regarding educational contents, the need for advanced cardiovascular resuscitation was greatest and the need for emergency delivery was lowest, but this difference was not significant. Conclusion When designing a curriculum for EMS providers in the future, segregation into similar groups is required to reflect their educational needs.

Myelofibrosis results from stimulation of bone marrow stromal fibroblasts by fibrogenic cytokines elaborated by neoplastic or reactive cells in the marrow. Chronic idiopathic myelofibrosis should be differentiated from secondary myelofibrosis resulting from bone marrow involvement of malignant lymphoma because these diseases have different therapeutic strategies. Myelofibrosis in systemic lupus erythematosus is an uncommon but well-recognized complication, and identifying an autoimmune myelofibrosis is important in diagnosing this benign cause of myelofibrosis. We report two cases of myelofibrosis presenting the clinical and radiologic findings that mimicked malignant lymphoma -a case of autoimmune myelofibrosis associated with systemic lupus erythematosus showing extensive lymphadenopathy and a case of chronic idiopathic myelofibrosis with focal intrasplenic extramedullary hematopoiesis- and discuss the importance of the clinical information and radiologic findings for the pathologic diagnosis of myelofibrosis.

OBJECTIVE: The mismatch in the demand and supply of emergency medical resources has been a constant issue in Korean emergency departments (EDs). This study analyzed the characteristics and actual utilization of medical bed resources in these EDs. METHODS: The emergency department utilization (EDU) rate was calculated using the Emergency Medical Resource Information System (EMRIS) on the available beds in EDs from April 2014 to January 2015. The EDU rate was analyzed according to the season, day of the week, time of day, and ED type. Furthermore, the ratio between the maximum and minimum EDU rates was also compared between the regions. RESULTS: A total of 14,889,750 data points were included. The EDU rate was relatively high during winter and on Sundays, and was highest between 20:00 and 22:00. The ratio between the maximum and minimum EDU rates according to the time of day was highest in Gyeongbuk (5.4) and lowest in Daegu (1.4). Moreover, the EDU rate according to the ED type was highest in the regional emergency medical center (66.7%). CONCLUSION: Significant differences were observed in the EDU rates according to the season, day of the week, time of the day, region, and ED type. Therefore, EMRIS should allocate resources based on the data on both the hospital and regional characteristics.
