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.

An odontoid process fracture is a serious type of cervical spine injury. This injury is categorized into three types based on the location of the fracture. Severe or even fatal neurological deficits can occur due to associated cord injury, which can result in complete quadriplegia. Computed tomography is the primary diagnostic tool, while magnetic resonance imaging is used to evaluate any associated cord injuries. These injuries can occur either directly from the injury or during transportation to the hospital if mishandled. There are two main treatment approaches: surgical fixation or external nonsurgical fixation, with various types and models of fixation devices available. In this case study, computed tomography follow-up confirmed that external fixation can yield successful results in terms of complete healing, even in cases complicated by other factors that may impede healing, such as pregnancy.

Caustic ingestion can produce a progressive and fatal injuries to esophagus, stomach and other organs. Reported exposure to acetic acid results injuries to gastrointestinal tract, hemolysis and disseminated intravascular coagulation is general, but causing hepatic necrosis by direct injuries are rare. A 47-year-old man visited our emergency medical center complaining odynophagia and abdominal pain after ingesting glacial acetic acid ($99\%$) with suicidal ideation. At the time of arrival, the patient complained mild abdominal pain but a few hours later the patient complained severe abdominal pain with markedly elevated liver enzymes. The Abdominal Computerized Tomography showed diffuse gastric wall edema and density of wedge shaped hypodense area in right hepatic dome showing focal hepatic necrosis without significant inflammation. This seems likely to be a direct effect of the noxious agent on hepatocyte involving the portal circulation.

Background: Despite improvements in safety performance, the number and severity of mining-related injuries remain high and unacceptable, indicating that further reduction can be achieved. This study examines occupational accident statistics of the Ghanaian mining industry and identifies priority areas, warranting intervention measures and further investigations. Methods: A total of 202 fatal and nonfatal injury reports over a 10-year period were obtained from five mines and the Inspectorate Division of the Minerals Commission of Ghana, and they were analyzed. Results: Results of the analyses show that the involvement of mining equipment, the task being performed, the injury type, and the mechanism of injury remain as priorities. For instance, mining equipment was associated with 85% of all injuries and 90% of all fatalities, with mobile equipment, component/part, and hand tools being the leading equipment types. In addition, mechanics/repairmen, truck operators, and laborers were the most affected ones, and the most dangerous activities included maintenance, operating mobile equipment, and clean up/clearing. Conclusion: Results of this analysis will enable authorities of mines to develop targeted interventions to improve their safety performance. To improve the safety of the mines, further research and prevention efforts are recommended.

Purpose: Blunt cardiac injuries (BCI) have a wide clinical spectrum, ranging from asymptomatic myocardial contusion to cardiac rupture and death. BCIs rarely require surgical intervention, but can be rapidly fatal, requiring prompt evaluation and surgical treatment in some cases. The aim of this study was to identify potential factors associated with in-hospital mortality after surgery in patients with BCI. Methods: The medical records of 15 patients who had undergone emergency cardiac surgery for BCI between January 2014 and August 2020 were retrospectively reviewed. We included trauma patients older than 18 years admitted to Regional Trauma Center, Gachon University Gil Medical Center during the study period. Clinical and laboratory variables were compared between survivors and non-survivors. Results: Non-survivors showed a significantly higher Injury Severity Score (p=0.001) and Abbreviated Injury Scale in the chest region (p=0.001) than survivors. American Association for the Surgery of Trauma-Organ Injury Scale Grade V injuries were significantly more common in non-survivors than in survivors (p=0.031). Non-survivors had significantly more preoperative packed red blood cell (PRBC) transfusions (p=0.019) and were significantly more likely to experience preoperative cardiac arrest (p=0.001) than survivors. Initial pH (p=0.010), lactate (p=0.026), and base excess (BE; p=0.026) levels showed significant differences between the two groups. Conclusions: Initial pH, lactate, BE, ventricular injury, the amount of preoperative PRBC transfusions, and preoperative cardiac arrest were potential predictors of in-hospital mortality.

Due to improvements in emergency resuscitation provided by rescue teams, more trauma victims who could have died due to sudden heart failure at the scene are brought to the hospital following resuscitation. Most of these patients present with major organ injuries and hypovolemic shock at the time of trauma. However, head trauma associated with sudden heart arrest is rare. Here, we report a case of ring fracture with pontomedullary laceration that led to sudden heart arrest.

항공기, 자동차를 포함하는 모든 수송수단 설계에 있어서 내추락성 설계가 강조되고 있으나, 심각한 부상 또는 사망으로 이어지는 사고는 지속적으로 발생해 왔고, 앞으로도 발생할 것이다. 심지어 생존 가능으로 분류되는 사고에서조차도 상당한 수준의 인명사고가 있어 왔음은 주지의 사실이다. 그러나 이러한 사고들이 반드시 불가피하다고만 할 수는 없다. 만약 좌석, 구속장치, 탑승공간 강도조건 등 탑승자 보호계통이 적절히 또는 바르게 설계된다면 추락상황에서의 생존성은 획기적으로 증대될 수 있다. 이를 위해서는 급격한 가속도 변화환경에서의 인체 허용한도 특성을 충분히 이해해야 하며, 이를 바탕으로 인체 허용한도 제한치 이내에서 하중조건이 유지되도록 탑승공간을 설계하여야 한다. 본 논문에서는 급격한 가속도 변화환경에서의 인체 허용한도의 중요성과 예측되는 추락환경 변화에 따른 설계요구도 변화 필요성을 강조함으로써 내추락성 설계에 대한 공감대를 넓히고자 한다.

There are ongoing debates on the effectiveness of the Serious Accidents Punishment Act (SAPA) on ensuring safety management and accident prevention, as the annual number of fatal injuries did not decrease even after its enforcement. However, for right appraisal of the effectiveness of SAPA, it must not only be rated based on direct outcomes such as the number of fatal injuries, but also on the indirect effects related to the improvement of the safety management of firms or organizations. A construction superintendent is one of crucial persons who ensure worker safety in construction sites. They must have a high safety consciousness for effective and appropriate safety management in construction sites. In this, the impact of the enforcement of SAPA on the safety consciousness of the construction superintendents is investigated to add a new dimension in the appraisal of the effectiveness of SAPA. DAGMAR-based safety consciousness assessment model is used to measure four safety consciousness components, i.e. awareness, comprehension, conviction, and action. Three hundred and five responses obtained from a survey conducted among construction superintendents are used to analyze the shift of the safety consciousness of the construction superintendents due to the enforcement of SAPA. The results reveal that awareness and comprehension components significantly improved after the SAPA enforcement. Conversely, conviction and action components slightly improved. They also reveal that the changes are more significant for construction superintendents affiliated to principal contractors, compared to those affiliated to subcontractors.

Background: Most traumatic tracheobronchial injuries are fatal and result in death. Some milder cases are not life threatening and are often missed at the initial presentation. Tracheobronchial rupture is difficult to diagnose in the evaluation of severe multiple trauma patients. We reviewed the traumatic tracheobronchial injuries at Konyang University and Eulji University Hospital and analyzed the clinical results. Materials and Methods: From January 2001 to December 2011, 23 consecutive cases of traumatic tracheobronchial injury after blunt trauma were reviewed retrospectively. We divided them into two groups by the time to diagnosis: group I was defined as the patients who were diagnosed within 48 hours from trauma and group II was the patients who diagnosed 48 hours after trauma. We compared the clinical parameters of the two groups. Results: There was no difference in the age and gender between the two groups. The most common cause was traffic accidents (56.5%). The Injury Severity Score (ISS) was 19.6 in group I and 27.5 in group II (p=0.06), respectively. Although the difference in the ISS was not statistically significant, group II tended toward more severe injuries than group I. Computed tomography was performed in 22 cases and tracheobronchial injury was diagnosed in 5 in group I and 6 in group II, respectively (p=0.09). Eighteen patients underwent surgical treatment and all four cases of lung resection were exclusively performed in group II (p=0.03). There were two mortality cases, and the cause of death was shock and sepsis. Conclusion: We believe that close clinical observation with suspicion and rigorous bronchoscopic evaluation are necessary to perform diagnosis earlier and preserve lung parenchyma in tracheobronchial injuries from blunt trauma.
