Purpose: Rollover motor vehicle crashes have a higher injury severity and fatality than other motor vehicle crash types. From a left-quarter turn rollover accident of 25-passenger bus, we intend to assess the injury of the occupant and the injury severities according to the occupants' position. Methods: We carried out the 3 steps investigation of occupants' interview, visiting the repair shop and using the police report. We analyzed injuries sustained by occupants, and compared injury severities considering column, row in occupant's position and passenger interaction Results: The rollover involved 14 passengers in the bus who were all old women except a man driver. The most common injury was in the upper extremity, with six occurrences being a left clavicle fracture. Major injuries including hemothorax and pneumothorax were diagnosed at left side of the occupant. In the comparison of injury severity among driver's column (left side), mid column and passengercolumn, ISS of passenger column was the highest ($9.9{\pm}7.4$, $8.8{\pm}5.5$, and $10.3{\pm}4.0$, respectively, p>0.05). The injury severity of multiple occupants by row was higher than that of single occupant (10.8 vs. 3, p<0.05). Conclusion: An occupant must fasten their seat belt to prevent an injury by passenger interaction in the left-quarter turn rollover accident of a bus.

Understanding the characteristics of truck-involved crashes is of keen interest because such crashes are highly associated with greater potential leading to severer injury. The purpose of this study is to identify factors affecting injury severity of truck-involved crashes on freeways. In addition, a binary logistic regression technique is applied to identify causal factors affecting truck crash severity under normal and adverse weather conditions. Major findings from the analyses are discussed with truck operations strategies including speed enforcement, variable speed limit, and truck lane restriction, from the safety enhancement point of view. The results of this study would be useful for developing traffic control and operations strategies to reduce truck-involved crashes and injury severity in practice.

In recent, technological advancement including a vehicle black box (VBB) has led to reducing such underreporting issues and errors of crash data. The objective of this study is to analyze the injury severity of cyclists on taxi-to-two wheeler crashes based on the accurate crash data collected from the VBB in taxi. This study defined the two wheelers as bicycle and motorcycle. To perform this study, we used the VBB data collected from taxis operating in Incheon, South Korea for a two-year period (2010-2011). An ordered probit model was applied to analyze the injury severity in crashes. As a result, new injury severity factors were found: increase of the crash speed of taxi, damage of crash-involved vehicles (i.e., taxi and/or two wheeler), not standing of cyclists after crash, and second or third impact of cyclists after first crash.

Objective: This study aims to draw the characteristics of occupational accidents occurred in cabling work, and assess accident severity based on occupational injury data. Background: Accident factors and accident risk are different by the place of work in cabling work. Field managers require information on accident prevention that can be easily understood by workers. However, there has been a lack of studies that focus on cabling work in Korea. Method: This study classifies 450 injured persons caused in cabling work by process, and analyzes the characteristics of occupational injuries from the aspects of age, work experience and accident type. This study also analyzes accident frequency and severity of injury. Results: Results show that preparing/finishing (33.3%) was the most common type of cabling process in injuries, followed by maintenance (28.4%), routing/income (23.1%) and wiring/installation (15.1%) process. The critical incidents in the level of risk management were falls from height in the routing/incoming process, and falls from height in the maintenance process. And, incidents ranked as 'High' level of risk management were slips and trips, fall from height and vehicle incident in the preparing/finishing process, and fall from height in the wiring/installation process. Conclusion and Application: The relative frequency of accident and its severity by working process serve as important information for accident prevention, and are critical for determining priorities in preventive measures.

The purpose of this study is to investigate factors influencing the severity of non-suicidal self-injury in an adult community sample. Participants with recent and repeated NSSI(N=54) completed self-reported questionnaire assessing frequency, method, and motivation of self-injury and the emotional regulation of cognitive reappraisal. Results indicated that intrapersonal motivations were endorsed more than interpersonal motivations, and were significantly related with NSSI severity. Also earlier onset was significantly related to NSSI severity. These findings support the emotional regulation model of NSSI and highlight the importance of intervention focusing on emotional regulations.

Purpose: To evaluate the association between time to surgery and injury severity score (ISS). Methods: Medical charts and records were reviewed for polytrauma patients who underwent trauma surgery from November 2014 to March 2016. The patients were divided into two groups based on the ISS. Results: Among the 217 operated patients, 22 patients underwent first and second surgery. The patients with an ISS over 17 (mean 13.0 days) had a longer interval between surgeries than patients with an ISS of 17 or less (mean 7.5 days) (p=0.031). One hundred and twenty-one patients only underwent elective surgery and there is a positive correlation between ISS and time to elective surgery (p<0.028, Pearson's correlation coefficient=0.224). Seventy-four patients underwent emergent surgery only. Among these, the patients with an ISS of 17 or less underwent general surgery (86%) but the patients with an ISS more than 17 underwent neurological surgery (47%). Conclusion: Patients with high ISS need critical care during the preoperative and postoperative period.

Purpose: The aim of this retrospective study was to evaluate the relationship between appearance and size of bone bruise and severity of anterior cruciate ligament (ACL) injury with magnetic resonance imaging (MRI), furthermore, to identify the mechanism of ACL injury by analyzing the footprint of bone bruise. Materials and Methods: Sixty-five subjects who was taken an MRI within 6 weeks after acute ACL injury were studied. All MRI showed ACL injury and associated bone bruises. Bone bruises were analyzed using Costa-Paz classification based on appearance and location and also scored using Kornaat bone bruise grading system based on size and location. The severity of the ACL injury was graded using a 4-point system (ie, grade 0-3) with oblique coronal MRI. Results: There was statistically significant correlation between Costa-Paz classification of bone bruises in lateral femoral condyle and grade of ACL injury. There were more type 2 lesions in partial tear group (grade 1, 2), however, type 3 lesions of Costa-Paz classification in complete tear group (P=0.037). Significant positive correlations were observed between Kornaat total bone bruise score and grade of ACL injury (P=0.014). Most common ACL injury mechanism was pivot shift injury. Other mechanisms were clip valgus injury, phantom foot injury, and hyperextension injury. Conclusion: It is highly suggested that appearance and size of bone bruise is related to severity of ACL injury after acute ACL injury. The foot print of bone bruise provides valuable clues to identify ACL injury mechanism.

Purpose: Bicycle riding is an increasingly popular sports and leisure activity in Korea. The aim of this study was to identify injury patterns of admitted patients who were injured from bicycle riding. Materials and Methods: This study examined 71 patients from Jan. 2008 to May 2009. There were 54 male and 17 female patients. We investigated the injured body parts, mechanisms of injury, location of injury, types of bicycles, purpose of bicycle riding, any concomitant luggage or passenger on rear seat, injury seasons and the helmet use. We analyzed the data using Injury Severity Score(ISS). Results: There were 11 cases of ISS 1, 41 cases of ISS 4, 2 cases of ISS 5, 13 cases of ISS 9, one case of ISS 13, two cases of ISS 16 and one case of ISS 29 among the 71 patients. 36 patients(50.7%) underwent surgery for upper and lower extremity injuries, two patients for vertebral body fractures, 8 patients for facial bone injuries and one patient for abdominal organ injury. There were 10 head injuries among whom three patients received treatment in ICU(4.2%). Conclusion: Bicycle riding can cause severe injuries with subsequent admission and major surgeries. Several measures including constructing more bicycle road, public campaign and wearing protective gears should be instituted.

Objectives: This study was intended to see the relationship between psychiatric consequences and injury severity following traffic accidents. Methods: We surveyed the 134 patients who were hospitalized from 1994 to 2003 at Chosun University Hospital for psychiatic disability evaluation following traffic accident. We reevaluate demographic factors from admission note. Psychiatric symptoms from mental status exam in medical records. Psychological tests(MMPI, BAI, BDI, K-WAIS) were done. Then we calculate the injury severity score and McBride's rate of disability due to diagnosis from emergency care hospital records. Their relationships were evaluated by statistical methods which were t-test and Pearson correlation analysis using SPSS-10. Results: When physical injury was not severe, suicidal attempt was more frequent and depression, hysteria, psychasthenia, psychopathic deviation subscales were high in MMPI. But when physical injury was severe, they have diffficulty in concentration, impaired orientation, and changed in IQ score. There was no relationship between physical injury severity and faking bad scales(F, Ds-r). Conclusion: We must not assume when physical injury was not severe, the severe sympomts are just faking for their benefit.

Purpose: In this study, the prognostic significance of the Injury Severity Score (ISS) and the height of fall in free-fall patients were investigated. Methods: The medical records of 179 victims of falls from a height who were brought alive to the Emergency Department of Gyeongsang National University Hospital between January 2003 and December 2007 were analyzed. The age, the sex of the patients, the rate of admission, the hospital stay, the site of injury, the severity of injury, the rate of surgery, the site of the fall and the presence of alcohol intoxication were evaluated by using a retrospective review of the medical records. Injury severity was measured by using the ISS. Patients were categorized into four subgroups according to the height from where they had fallen. The data were statistically analyzed with using SPSS ver. 10.0. Results: The admission rates for the subgroups with falls of less than 3 stories were significantly lower than those for the subgroups with higher heights of falls (70.7% vs. 100%, p<0.05). These two subgroups showed statistically significant differences in mean hospital stay ($17.11{\pm}24.88$ vs. $56.73{\pm}49.21$, p<0.05), rate of operation (30.6% vs. 53.8%, p<0.05), and mean ISS ($6.86{\pm}4.97$ vs. $13.96{\pm}9.14$, p<0.05). In the correlation analysis, the ISS and the mean hospital stay showed the highest correlation with correlation coefficient of 0.666. Conclusion: In this retrospective analysis of 179 free-fall patients, we evaluated the prognostic factors affecting the outcomes for the free-fall patients. The patients who had fallen from heights of 3 stories or higher showed statistically significant higher rates of admission, longer durations of hospital stay, higher ISSs, and higher operation rates. The most accurate factor in predicting the length of hospital stay was the ISS.
