Purpose: Recently, as the number of people who enjoy water sports life in river or lake easy to accessible are increasing, that of the patients who are injured in water sports also does gradually. We intend to investigate the type of the injured patients of water sports and the riskiness of the sports in this study. Methods: We retrospectively looked into the medical records of the patients who were injured in water sports and visited a general hospital in Gangwondo-province from 2010 to 2015. Results: Total 146 patients came to the hospital during six years. Patients mostly occurred at younger ages, in summer, and on holidays, rather than weekdays. The most common lesions of injuries were faces (53 patients). The most common types of injuries were contusions (62 patients), followed by fractures (32 patients) and lacerations (26 patients). The most frequent fracture sites were the upper extremities (11 patients). Most of the trauma patients were mild, but a small number of patients with aspiration pneumonia occurred and their severity was higher than trauma patients. Conclusions: In this study, facial injuries were most frequent in water sports injuries. In the fractures, upper extremities were the most common fractured lesions. In addition, even if there is no direct trauma, aspiration pneumonia is serious, so caution should be taken with protective equipment suitable for water sports.

This paper summarizes recent research in the use of the psychophysical method of adjustment to establish acceptable parameters for upper extremity work activities. Results from these studies show that this psychophysical approach can provide reliable guidelines based upon realistic job conditions which involve one or more risk factors for cumulative trauma. It is also shown that this method provides advantages over other psychophysical methods as well as current biomechanical and physioligical criteria.

Background: Rib fractures are the most common type of thoracic trauma and cause other complications. We explored the risk factors for pneumonia in patients with multiple rib fractures. Materials and Methods: Four hundred and eighteen patients who visited our hospital with multiple rib fractures between January 2002 and December 2008 were retrospectively reviewed. Chest X-rays and chest computed tomography were used to identify injury severity. Patients with only a single rib fracture or who were transferred to another hospital within 2 days were excluded. Results: There were 327 male patients (78%), and the median age was 53 years. The etiologies of the patients' trauma included traffic accidents in 164 cases (39%), falls in 78 cases (19%), slipping and falling in 90 (22%), pedestrian accidents in 30 (7%), industrial accidents in 41 (10%), and assault in 15 (4%). The median number of rib fractures was 4.8. Pulmonary complications including flail chest (2.3%), lung contusion (22%), hemothorax (62%), pneumothorax (31%), and hemopneumothorax (20%) occurred. Chest tubes were inserted into the thoracic cavity in 216 cases (52%), and the median duration of chest tube insertion was 10.26 days. The Injury Severity Score (ISS) and rib score had a median of 15.27 and 6.9, respectively. Pneumonia occurred in 18 cases (4.3%). Of the total cases, 33% of the cases were managed in the intensive care unit (ICU), and the median duration of stay in the ICU was 7.74 days. Antibiotics were administered in 399 patients (95%) for a median of 10.53 days. Antibiotics were used for more than 6 days in 284 patients (68%). The factors affecting pneumonia in patients with multiple rib fractures in multivariate analysis included age (p=0.004), ISS (p<0.001), and rib score (p=0.038). The use of antibiotics was not associated with the occurrence of pneumonia (p=0.28). In-hospital mortality was 5.3% (n=22). Conclusion: The factors affecting risk of pneumonia in patients with multiple rib fractures included age (p=0.004), ISS (p<0.001), and rib score (p=0.038). Elderly patients with multiple traumas have a high risk of pneumonia and should be treated accordingly.

Purpose: The human face is the most exposed part of the body, and in patients with simple or complex trauma from traffic accidents, industrial calamities, sports injuries, human assaults, and daily accidents, facial trauma occupies an important portion. The etiology of facial trauma vary on a society's economic, cultural, and environmental status. Methods: Regarding patients who were admitted from between the years 2000 to 2009 at the Hanyang University hospital, the authors studied how the changes in the economic status in the past 10 years of our country influences the incidence of facial bone fractures. Results: In this study, 1) The unemployment rate showed a strong negative relationship with the total number of inpatients with facial bone fractures, the number of male patients, the number of female patients, the number of patients with facial bone fractures caused by fall down, the number of patients who were admitted for shorter than 7 days, and the number of the facial bone fracture patients with their age in the twenties. 2) The consumer price index showed a strong positive relationship with the number of female patients, the number of patients who were admitted for shorter than 7 days, and the number of the facial bone fracture patients with their age in the teens and fifties. Conclusion: Looking at the results of correlation analysis and multiple regression analysis with economic indicators, the unemployment rate showed negative influence to the total number of inpatients with facial bone fractures, and the number of inpatients with facial bone fractures caused by fall down, with statistical significance.
