Trauma to the head and neck region can have serious consequences for vital organs such as the brain, and injuries to blood vessels can cause permanent neurological damage or even death. Thus, prompt treatment of head and neck vessels is crucial. Although the level of evidence is moderate, an increasing amount of research indicates that endovascular treatments can be a viable alternative to traditional surgery or medical management. Embolization or reconstructive endovascular procedures can significantly improve patient outcomes. This article provides an overview of various endovascular options available for specific clinical scenarios, along with examples of cases in which they were employed.

Nowadays according to the complexity of our daily life due to the development of industry and transportation various kinds of injuries happen. Since 1993 the death rate among 5-14 age children by injuries amount to about 57%. Furthermore, the injury of children can give a direct damage to their own family and it can also bring a serious loss to the country as well as the community where they live in accord with degree of an injury. From this reason, the importance of safety education has been increasing. In this study, it is aimed to clarify the effect of injury preventive behaviors on injury incidence of the 6th grade students in the elementary school. This study is accomplished by the survey sampled from 9 elementary schools in seoul, each of which belong to different district. The survey took for 15 days from the date of september 10th 1996 to september 25th 1996 and the results were as follows; 1. For demographic characteristic, sexual distribution was 48.7% of male students and 47.1% of female students. The required time from home to school was 10-19 minutes(51.8%), and the most way of their going to school is to walk(89.7%). Mothers who graduated from high school were 46.6% and 49.4% of fathers were above university graduated level. The most vocation of mothers was housewife as 56.7%. 2. The results of analysis on the injury rates, 75.8% of children experienced more than one injury and the most was play injury. With regards to sites where injuries happened, the room, the kitchen, and the living room in the house ranked first(38.3%) and then injuries at school such as on the playground, in the classroom, and on the stairs was 34.1%. 3. Considering the rate of injury incidence in accordance with demographic characteristics, male students experienced more injuries than female students(p〈0.05). For the way from home to school, children who went to school by bicycle experienced the most injuries and then on foot, by bus in order of which differences were statistically significant(p〈0.05). 4. From the comparison of parents' safety education practice and the injury incidence, the less often parents practice safety education, the more often children experience injuries(p〈0.05). 5. The results of analysis on the effect of injury preventive behaviors on accidents children who didn't act injury preventive behaviors experienced much more injuries than those who did injury preventive behaviors of which differences were statistically significant(p〈0.01). 6. From the results of analysis of factors effecting on the elementary school children's injuries, children without injury preventive behaviors had more effect on accidents than those who had injury preventive behaviors as odds ratio 2.06(p〈0.01), and the odds ratio of male students compared with female students was 1.47(p〈0.05).

Purpose: This study aimed to determine the risk factors associated with the severity of fall-related injuries among patients who suffered a fall from similar heights and analyze differences in injury sites according to intentionality and injury severity. Methods: The Emergency Department-based Injury In-depth Surveillance (EDIIS) data collected between 2019 and 2020 were used in this retrospective study. Patients with fall-related injuries who fell from a height of ≥6 and <9 m were included. Patients were categorized into the severe and mild/moderate groups according to their excessive mortality ratio-adjusted Injury Severity Score (EMRISS) and the intention and non-intention groups. Injury-related and outcome-related factors were compared between the groups. Results: In total, 33,046 patients sustained fall-related injuries. Among them, 543 were enrolled for analysis. A total of 256 and 287 patients were included in the severe and mild/moderate groups, respectively, and 93 and 450 patients were included in the intention and non-intention groups, respectively. The median age was 50 years (range, 39-60 years) and 45 years (range, 27-56 years) in the severe and mild/moderate groups, respectively (P<0.001). In multivariable analysis, higher height (odds ratio [OR] 1.638; 95% confidence interval [Cl], 1.279-2.098) and accompanying foot injury (OR, 0.466; 95% CI, 0.263-0.828) were independently associated with injury severity (EMR-ISS ≥25) and intentionality of fall (OR, 0.722; 95% CI, 0.418-1.248) was not associated with injury severity. The incidence of forearm injuries was four (4.3%) and 58 cases (12.9%, P=0.018) and that of foot injuries was 20 (21.5%) and 54 cases (12.0%, P=0.015) in the intention versus non-intention groups, respectively. Conclusions: Among patients who fell from a similar height, age, and fall height were associated with severe fall-related injuries. Intentionality was not related to injury severity, and patients with foot injury were less likely to experience serious injuries. Injuries in the lower and upper extremities were more common in intentional and unintentional falls, respectively.

This study investigated social relief schemes for serious adverse drug reactions in foreign countries and deduced lessons and implications for Korea to implement the scheme. A social relief scheme for serious adverse drug reactions provides reliefs for diseases and such health effects as disabilities or deaths that were caused by adverse reactions to pharmaceuticals prescribed at hospitals and clinics as well as those purchased at pharmacies notwithstanding their proper use. The US and the UK do not have specific relief schemes for adverse drug reactions but apply rules of strict liability or negligence. New Zealand and Nordic countries provide no-fault compensation schemes for health effects or injuries caused by medical treatments or medicinal products. Japan and Taiwan have operated the schemes since 1980 and 2000, respectively. In designing the scheme in Korea, we suggested that cases eligible for relief be confined to serious adverse reactions such as death or disability and then extended to diseases. It is desirable to encourage the reporting system of adverse drug reactions and quality use of medicines for the relief scheme to work efficiently.

Spinal cord injury (SCI) is a serious condition associated with social and familial burden, as well as significant neurologic deficit. Despite the many advances in the treatment of spinal cord injury, a fundamental treatment for neurologic functional recovery has not yet been developed. In this article, we review two directions of development for spinal cord injury treatment: neuroprotective pharmacological agents and axon-regenerating cell therapy. We expect developments in these two to lead to improve functional recovery in patients with spinal cord injuries and to reduce burdens on society, as well as the patients' families.

A review of accidents involving farm machinery, which occurred in Korea during 2002, shows that $90.7\%$ of farm-work accidents and $9.3\%$ of traffic accidents were linked to agricultural machinery. The frequency of accidents per annum amounts to 72.2 out of 10,000 vehicles, $94.4\%$ of which relates to tillers and tractors. An analysis of the causes of the accidents revealed that $49.1\%$ of farm-work accidents were due to the tiller driver's fault or error. In the case of traffic accidents, $83\%$ of farm machinery mishaps were found to be due to violation of traffic regulations while $60.4\%$ of the farm machinery damage resulted from faulty driving or lack of safe driving practices. The average casualty count of farm machinery-related accidents is 1.39 persons per case, which consist of 0.07 deaths, 0.74 serious injuries, and 0.58 slight injuries.

We have shown in Part I [1] of this study that medical needle-stick injuries are causing serious health problems to healthcare personnel and other professionals that require the attention of healthcare and textile researchers to develop new protective systems. Responding to such need, a needle force measurement device that is capable of measuring dynamic forces experienced by medical needles during needle penetration through protective articles was developed and described in part I. This paper reports the results of evaluation of protective woven fabrics from high performance fibers and standard and bifid medical needles using the force measurement system. The woven fabrics varied in cover factor, number of layers, and orientation angle. Standard and bifid needles with different gap widths were used to evaluate the resistance of the fabric to needle penetration.

Conveyors cause a high serious and fatal injuries in the industry. Every year people are hurt or killed as a result of accidents on conveyors. Most accidents occur during operation and maintenance when employees are working on moving, unguarded conveyors or when the conveyors starts unexpectedly. In 2008 there were 486 reported injures ranging from fatalities to injures. Of these 486 reported accidents, 8 were fatalities, 66.9%(325) of reported accidents occurred in manufacturing company and 43.8%(213) occurred at the belt conveyors. The objective of this study was to invent the remote emergency stop device because industrial accidents mainly occur at blind spots where usually do not have any safety guard or device rather than the normal working places. In principle, this new device will use with the existing safety system. Then, it will be powerful safety system for preventing injuries related with conveyors.

Traumatic spinal cord infarction is a rare condition that causes serious paralysis. The regulation of spinal cord blood flow in injured spinal cords remains unknown. Spinal cord infarction or ischemia has been reported after cardiovascular interventions, scoliosis correction, or profound hypotension. In this case, a 52-year-old man revisited the emergency center with motor and sensory abnormalities in all four extremities 56 hours after a motor vehicle collision. Despite the clinical presentation and imaging examination, there were no specific findings on the patient's first visit to the trauma center. Cervical spine computed tomography angiography showed a narrow vertebral artery, and diffusion-weighted imaging revealed spinal cord infarction from C3 to C5 with high signal intensity. It should be kept in mind that delayed-onset spinal cord infarction may occur in minor or major trauma patients as a result of head and neck injuries.

Abusive head trauma (AHT) is the most common and serious form of child abuse and a leading cause of traumatic death in infants and young children. The biomechanics of head injuries include violent shaking, blunt impact, or a combination of both. Neuroimaging plays an important role in recognizing and distinguishing abusive injuries from lesions from accidental trauma or other causes, because clinical presentation and medical history are often nonspecific and ambiguous in this age group. Understanding common imaging features of AHT can increase recognition with high specificity for AHT. In this review, we discuss the biomechanics of AHT, imaging features of AHT, and other conditions that mimic AHT.
