본 연구에서는 한국의 제품 안전관리를 위한 시나리오 기반의 리스크 평가기법을 개발, 제시한다. 이를 위해 먼저 한국의 제품 안전관리를 위한 관련 규제정책을 살펴보고, 이 법의 시행을 위해 필요한 제품 리스크 평가기법을 일반상해의 경우와 유해물질의 경우로 구분하여 제시한다. 본 연구에서 제시되는 리스크 평가기법의 특징은 다음과 같다. (i) 제품의 사용 시 발생할 수 있는 부상 시나리오에 기반을 둔 방법이다. (ii) 시나리오 발생 확률과 인체에 미치는 부상 심각도를 바탕으로 리스크를 평가한다. (iii) 유해물질 함유 제품의 경우 유해물질의 인체에의 위해성 여부를 확인한 후 부상 심각도를 고려해서 리스크를 평가한다. 부상 시나리오의 확률을 결정하기 위하여 본 연구에서는 시나리오를 몇 가지 구성 요인으로 분해하고 이들 각각의 요인 확률을 추정하여 전체 시나리오의 확률을 결정한다. 본 연구에서 제시된 기법을 통하여 리스크 평가를 수행한 결과를 제시하고 이를 제품 안전관리를 위한 품목 분류에 활용할 수 있음을 보인다.

Recently the Emergency Response is very important issue in Korea because there are lots of damage of people and property. In this paper, we have studied person's injury related to emergency action to minimize the damage on KTX. We defined what Activities of the emergency response workers should take when the Person's injury occurs on the railway. This has been possible through the development of the scenario that is focused on the person's injury accident. We considered all kinds of environment of KTX related to emergency action of person's injury accidents. Finally, we developed the role and responsibility of emergency response workers against KTX person's injury accidents.

The objective of this study is to develop qualification analysis preliminary frame for railway personal injury accident. In this research, we develop accident scenarios to analyze systematically and evaluate quantitatively fatality accident scenarios for railway personal. The accident scenario analysis first identifies the hazardous events and explains the hazardous conditions that surround the accident and cause railway accidents. This method includes a feasibility test, a clustering process and a pattering process for a clearer understanding of the accident situation. Since this method enables an accident scenario analysis to be performed systematically as well as objectively, this method is useful in building better accident prevention strategies. Therefore, this study could serve to reduce railway accidents and could be an effective tool for a hazard analysis.

Purpose: This study aimed to design user interfaces of a mobile application for managing pressure injury patients in a long-term care hospital based on the user's needs. Methods: To reflect users' needs in the mobile application, the user interfaces in this study were designed in five steps: brainstorming and mind mapping, persona and scenario, needs list and priority, a draft version of flow chart and user interfaces and expert review. These steps were conducted with a step nurse at a long-term care hospital, a professor who majored in nursing informatics, a professor who had lots of research experiences about pressure injury and a wound ostomy continence nurse. Results: Two personas, scenarios and needs' lists were derived. Listed Needs included the followings; Accurate staging of pressure injury; Appropriate management by staging; Acquisition of professional knowledge about pressure injury; Acquisition of easy pressure injury information through text, picture and video; and Sharing pressure injury information in unit. The structure, menus and features of the pressure injury mobile application were visualized with user flow based on two personas' scenarios and needs' lists. Conclusion: Our study suggests and visualizes the key features of the 'Pressure Injury Guide', a pressure injury management mobile application for nurses in a long-term care hospital, which can be utilized by nurses, application developers, and related researchers.

Among the themes for CSR(Corporate Social Responsibility), consumer issues include protecting the health and safety of consumers who purchase and use the products. In particular, ensuring product safety is a major theme of consumer issues for corporate social responsibility. Currently, the government implements the Electrical Appliances and Consumer Products Safety Control Act for product safety management and selects products that may harmful to consumers as safety control items, and manages the products by designating them as 4 types of safety certification, safety confirmation, supplier conformity verification, and safety standard compliance. In this paper, we propose management plans for the establishment of a more reasonable classification type of safety management target for 48 items of consumer products to be controlled by the act, and confirm the validity of the plan. First, we perform cluster analysis using data for CISS (Consumer Injury Surveillance System) to derive a new classification type of the safety management target. Next, we compare the results of the cluster analysis with the classification type of the act and the existing scenario classification method RAS (Risk Assessment by Scenario) and the causal network method RAMP (Risk Assessment Method based on Probability). Based on these results, we propose two new plans of safety management target classification and verify its validity.

A 24-year-old man presented to King Saud Medical City emergency department with a retained bullet in his penis following a civilian exchange of gunfire. After an initial assessment, the patient was taken to the operating room. Penile exploration was performed, the bullet was extracted successfully, and the corpora cavernosa were repaired properly. A 6-week follow-up showed full healing with preservation of erectile function. Immediate surgical intervention is mandatory as the primary treatment for penile gunshot injury to ensure proper anatomical and functional recovery.

차대 보행자 교통사고는 발생빈도에 비하여 사망률이 매우 높은 특징이 있다. 전세계적으로 정부 및 보험사에서는 보행자 보호를 위한 새로운 안전기준을 수립 및 강화하는 추세이다. 보행자 보호 성능을 향상시키기 위하여 한국정부는 2007 년부터 신차안전도평가에서 보행자 안전을 평가하고 있다. 보행자 보호 성능은 점진적으로 향상되었으나 여전히 미흡한 상태이다. 전개형 후드 및 보행자 에어백 등으로 구성되어 있는 보행자 보호 시스템은 보행자 보호를 위한 대안이 될 수 있다. 보행자의 머리상해기준값을 감소시키기 위하여 새롭게 정의된 설계방법론을 바탕으로 보행자 에어백 설계 절차를 제안하였다. 제안된 설계방법론을 실용적인 측면에서 검토하였고 보행자 보호 시스템의 제작에 적용이 가능하다.

Penetrating brain injury caused by a nail gun is an uncommon clinical scenario reported in the literature. A 36-year-old male presented with a nail that had penetrated through the occipital bone. He was alert and neurologically intact except for visual disturbance. Computed tomography (CT) of the brain showed the nail lodged at the occipital lobe and the parietal lobe, with minimal intracerebral hemorrhage. The nail was placed in the occipital lobe close to the superior sagittal sinus. We removed the nail with craniotomy since the entrance of the nail was close to the superior sagittal sinus. There were no newly developed neurological deficits postoperatively. Immediate postoperative CT showed no newly developed lesions. The patient recovered well without any significant complications. Two weeks postoperatively, magnetic resonance imaging showed no remarkable lesions. The visual disturbance was followed up at the outpatient department. To summarize, we report a rare case of penetrating head injury by a nail gun and discuss relevant aspects of the clinical management.
