Chest injuries due to blunt trauma often result in severe derangements that lead to death. And we have to diagnose and treat the patients who have blunt chest trauma immediately and appropriately. A clinical analysis was made on 324 cases of chest injury due to blunt trauma experienced at department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyung Hee University during 8-year period from 1972 to 1979. Of 324 patients of blunt chest injuries, there were 189 cases of rib fracture, 121 of hemothorax or/and pneumothorax, 108 of soft tissue injury of the chest wall only, 41 of lung contusion, 24 of flail chest, 13 of scapular fracture, 7 of diaphragmatic rupture and others. The majority of blunt chest injury patients were traffic accident victims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 3rd decade and 4th decade [60%] and 238 patients were male comparing to 86 of female [Male: Female = 3:1 ]. In the patients who have the more number of fractured ribs, the more incidence of intrathoracic injury and intraabdominal organ damage were found. The principal associated injuries were head injury on 58 cases, long bone fractures on 37, skull fractures on 12, pelvic fractures on 10, renal injuries on 6 and intraabdominal organ injuries on 5 patients. The principle of early treatment of chest injury due to blunt trauma were rapid reexpansion of the lung by closed thoracotomy which was indicated on 96 cases, but open thoractomy was necessary on 14 cases because massive bleeding, intrapleural hematoma and/or fibrothorax, or diaphragmatic laceration-On 15 cases who were young and have multiple rib fracture with severe dislocation delayed elective open reduction of the fractured ribs with wire was done on the purpose of preserving normal active life. The over all mortality was 2.8% [9 of 324 cases] due to head injury on 3 cases, massive bleeding on 2,wet lung syndrome, acute renal failure on 1 and septicemia on 1 patient.

Objectives: This retrospective study aims to evaluate the prevalence of maxillofacial trauma in a developing country, along with its pattern, etiology and management. Data for the present study were collected from the Department of Dentistry, ESIC Medical College and Post Graduate Institute of Medical Sciences and Research, Chennai in India. Materials and Methods: The medical records of patients treated for maxillofacial injuries between May 2014 and November 2015 were retrospectively retrieved and analyzed for prevalence, pattern, etiology, and management of maxillofacial trauma. SPSS software version 16.0 was used for the data analysis. Results: Maxillofacial fractures accounts for 93.3% of total injuries. The mean and standard deviation for the age of the patients were $35.0{\pm}11.8$ years and with a minimum age of 5 years and maximum age of 75 years. Adults from 20 to 40 years age groups were more commonly involved, with a male to female ratio of 3:1. There was a statistically significantly higher proportion of males more commonly involved in accident and injuries (P <0.001). Conclusion: The most common etiology of maxillofacial injury was road traffic accidents (RTA) followed by falls and assaults, the sports injuries seem to be very less. In RTA, motorized two-wheelers (MTW) were the most common cause of incidents. The majority of victims of RTA were young adult males between the ages of 20 to 40 years. The malar bone and maxilla were the most common sites of fracture, followed by the mandible. The right side of the zygomatic complex was the predominant side of MTW injury. The majority of the zygomatic complex fractures were treated by conservative management. Open reduction and internal fixation were performed for indicated fracture patients.

Fall is very fatal accident causes death to older people. Shoe may affect to fall. Shoe influences risk of slips, trips, and falls by altering somatosensory feedback to the foot. The purpose of this study was to investigate the analysis of non-slip shoes for older people and influence on older people's lower extremity. For this study twenty three healthy older people were recruited. Each subjects walked over slippery surfaces (COF 0.08). Four pairs of non-slip shoes (shoe A had the greatest COF, 0.23 while shoe B, C, and D had smaller COF relatively) for older people were selected and tested mechanical and biomechanical experiment. For data collection motion capture and ground reaction forces were synchronized. There were statistically significant differences for slip-displacement, coefficient of friction, braking force, propulsion force, knee range of motion and knee joint stiffness by shoes. It was concluded that shoe A was the best for non-slip function because of the lowest slip displacement, the highest braking and propulsion forces, and the highest mechanical and biomechanical coefficient of friction where as shoe B, C, D were identified as a negative effect on the knee joint than shoe A. To prevent fall and slip, older people have to take a appropriate non-slip shoes such as shoe A.

Purpose: Injuries are the most important cause of morbidity and mortality in the childhood population worldwide. Thus, this study was down to investigate the type and the severity of injuries according to the age group in childhood. Methods: A survey of injury information and a chart review were done on 378 children (257 boys, 121 girls) who visited the Emergency Departments of Asan Medical Center from March 1, 2009, to March 31, 2009. To determine differences in injury mechanism, accident place, injury site, New Injury Severity Score (NISS) and Pediatric Trauma Score (PTS), we divided the 378 patients into 4 group: under 1 year, 1 to 4 years, 5 to 9 years, and 10 to 15 years. Results: The mean (${\pm}SD$) age of the study group was 5.1 (${\pm}4.4$) years. Two year olds formed the largest group of injured children, with 77 cases (20.4% of the total). The most common cause of injury in childhood was being hit by an object (26.2%). Falls were frequent in the under-1-year group (22.2%) and slip downs (30.1%) were more frequent in 1-to-4-year group. More than half (53.4%) of the injuries occurred in the home, and the most common places of home-related injuries were the living room (41.1%) and the bedroom (31.2%). The mean (${\pm}SD$) NISS was 1.5 (${\pm}1.8$), and traffic accidents had the highest NISS ($2.8{\pm}5.1$). Injuries occurred most frequently during the evening. The peak period was 4:00 PM to 8:00 PM (33.7%). Conclusion: Patterns of childhood injury by age group were considerably different, and less severe and nonhospitalized injuries were common. Thus, need to improve surveillance of a variety of injuries, promote intersectional collaboration, build institutional capacities and mobilize community support and policy as an investment in prevention.
