Purpose: We aimed to provide effective emergency medical services (EMS) response strategies for coping with high acuity patients during the pandemic by analyzing the influence of the COVID-19 and social distancing on EMS. Methods: In this retrospective observational study, we analyzed the distribution of high acuity patients transported by Daejeon 1-1-9 EMS during the COVID-19 pandemic period, between February 1, 2020 and October 31, 2020 and the same period in 2019, as well as the level 3 social distancing enforced period, between July 27, 2020 and October 31, 2020. Results: The EMS dispatches decreased by 17% during the observed COVID-19 pandemic period compared to the same period in 2019. The number of cases with cardiac arrest and positive prehospital stroke scale rose by (p<.001). Patients with cardiac arrest, trauma, and positive prehospital stroke scale increased by during the level 3 social distancing period. Conclusion: Unlike the decreased EMS call volume and patient transports during the COVID-19 pandemic, cardiac arrest cases and the severity of high acuity patients tended to increase. We suggest that EMS systems should contrive a response strategy considering the collateral effect of major epidemics on the incidence rate of high acuity patients.

Although attention to terrorism has increased sharply in recent years within many countries, it is by no means a new phenomenon. Majority of these countries have limited regulations or guidelines about terrorism. LOP (Level Of Protection) can be consider as a first step. This paper seeks to present a process to determine LOP and allowable damage. LOP is determined by asset value reason why it should be based on cost. The asset value is defined as "cost induced when asset is damaged". For example, the collateral damage outside the facility should be taken in consideration in the asset value. Allowable structural damage is assigned depending on LOP.

Eleven cases of peripheral arterial injuries treated at Korea University Woo Sok Hospital during these 3 years and 3 months from Feb. 1971Eleven cases of peripheral arterial injuries treated at Korea University Woo Sok Hospital during these 3 years and 3 months from Feb. 1971 to May 1974 were reviewed. Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries during operation. Of the 11 arterial injuries 3 were femoral artery which` was the commonest in frequency and the next was 2 cases of brachial artery. The most frequent type of injury was transection. Laceration, contusion and spasm was also recognized. The need to operate immediately following an injury was emphasized. Operative procedures were end to end anastomosis and saphenous vein graft in 5 and 2 cases, respectively. Other cases were undergone multiple suture ligature due to staphyllococcal infection, insertion of polyethylene catheter, and lateral suture after thromboendarterectomy. Fractures and extensive soft tissue damage associated with arterial injuries with widespread destruction of the collateral circulation aggravated the situation and complicated the amputation of lower extremity in 4 cases. The factors influencing the amputation were time lag, presence of associated injuries and complications.[KTCS 1974;1:109-116] Common causes of injuries were stab wound, automobile accidents and iatrogenic injuries during operation.

정보화 사회에 있어서 피해자는 범죄원인의 제공자로서 특성과 보호대상으로서의 특성이 공존하고 있다. 이러한 상반된 특성이 피해자학의 변천과 그 피해자학의 발전을 가져왔다. 그 결과 피해자화에 따른 피해의 분류가 일반화되었다. 즉 범죄로 인한 직접피해를 제1차 피해라고 하며, 그리고 제 1차 피해로 인하여 수적으로 발생되는 피해를 제2차 및 제3차 피해로 구분할 수 있었다. 본 논문은 이와 같은 피해분류의 원인에 따라 각국의 범죄피해자 대책을 살펴보고 한국의 문제점올 고찰하였다.

목적: 관절경하 후방 십자 인대 재건술시 지혈대의 필요성에 대한 언급된 문헌이 없어 지혈 대 없이 시행하는 본원의 관절경하 후방십자인대 재건술 결과 및 술기에 대해 보고하고자 한다. 대상 및 방법: 1998년 1월부터 2003년 5월까지 본원에서 후방십자인대 손상으로 관절경을 시행한 75례중 외측 측부인대 및 후외측 측부인대와 같은 동반손상으로 인해 관절외적 시술로 지혈대를 시행한 환자 16례와 술후 추시관찰이 12개월 이하인 10례를 제외한 49례의 단독 후방 십자 인대 손상 환자를 대상으로 하였고 자가 골-슬개건-골을 이용하여 재건한 경우 13례, 동종 골-슬개건-골을 이용하여 재건한 경우 19례, 동종 아킬레스 건을 이용하여 재건한 경우 17례였다 평가방법은 49례를 Lysholm knee scoring scale을 이용하여 비교하였다. 결과: 지혈대 없이 관절경하 후방 십자 인대 재건술을 한 경우 수술시간은 평균 105분 소요되었으며, 출혈로 인해 시야가 혼탁하여 지혈대를 사용한 경우는 없었다. 모든 환자에서 수술 부위의 부종, 국소 종창, 울혈, 환부 감염등은 관찰되지 않았다. Lysholm knee scoring scale을 이용한 평가 결과는 자가 골-슬개건-골을 이용한 경우는 평균 74점(fair) , 동종 아킬레스 건을 이용한 경우 75점(fair) , 동종 슬개건-골을 이용한 경우는 76점(fair)였다 결론: 관절경하 후방십자인대 재건술시 지혈대를 사용하지 않아도 수술에 어려움은 없으므로 지혈대 없이 재건술을 시행함으로써 지혈대로 인해 야기되는 합병증을 방지할 수 있을 것으로 생각된다.

우리나라 도로교설계기준(2005)에서 규정하고 있는 내진설계의 기본개념은 인명피해를 최소화하고 설계지진은 구조물 수명동안 발생할 확률이 거의 없다는 것이다. 구조물 내진설계의 가장 상위개념이며 합리적인 내진대책은 인명피해를 최소화해야하며 경제성이 있어야 한다. 결과적으로 최우선의 목표를 만족시키기 위해서는 개별적인 구조물 중심이 아닌 도시 전체를 대상으로 한 거시적인 평가방안이 필요하다. 도시지역에 대한 피해상황은 기타지역과 다른 양상을 나타내며, 도시가 거대해질수록 구조물의 파손에 의한 손실보다는 오히려 이에 수반되는 부가적인 손실이 월등히 클 것이다. 그리고 거시적인 지진재해 평가방법은 인구와 구조물이 밀집되고, 정치 경제활동 등의 중심이 되는 오래된 도시일수록 효과가 탁월할 것이다. 본 연구는 지진재해위험을 합리적으로 예측할 수 있는 지진재해위험지수를 개발하고, 서울특별시를 6개 구역으로 분할하여 상대적인 지진재해위험을 평가하였다.

The shape of combustion nozzles varies from large diameter to small diameter ones. In the case of small nozzle, nozzle exit can be easily winkled or damaged in machining process. Femtosecond laser is a micro machining technology that is able to drill a small nozzle without damaging the nozzle exit. In this experiment, a small nozzle of combustion was fabricated by using a femtosecond laser. The fabricated nozzle of combustion provided a very small nozzle diameter with clean nozzle exit without wrinkling or collateral damage.

In 2022, construction had a five fold higher accident and fatality rate compared to the overall industry. The Construction Technology Promotion Act requires parties in construction contracts to calculate safety costs following Ministry of Land, Infrastructure and Transport guidelines. Understanding safety expense components is vital for evaluating accident prevention costs and planning anti-accident strategies. A study surveyed safety professionals to analyze the importance and influence of safety management expense components, providing basic data for future research. Survey results highlighted the significance of safety management plans, structural safety assurance, and preventing collateral damage.

Herein, we present a case of a successful treatment of persistent type 2 endoleaks associated with aneurysmal sac enlargement after endovascular aneurysm repair in an elderly patient. We confirmed the diagnosis by abdominal computed tomography and selective angiography revealing an 11.0-cm aneurysm sac with type 2 endoleaks. An attempt for the endovascular embolization of collateral arteries was unsuccessful due to anatomic variations and their multiple complex communications. Instead, transperitoneal sacotomy and direct suturing on the feeding target vessels was successfully performed without any endograft damage. In conclusion, sacotomy appears to be a feasible therapeutic substitute where endovascular or other techniques have a high risk of failure and lead to unsuccessful results.

Objective : Generally speaking Reverting yin disease pattern(厥陰病) is the last step in cold damage(傷寒). Therefore recognized Yin cold disease(陰寒病) is increasing, and resist action One Yang qi(一陽) began to creep into body. But Ke Qin(柯琴) have a different way of thinking that Reverting yin disease pattern connected with the loss of Liver's function. Liver qi depression(肝鬱) make a ministerial fire(相火), and it make a nutrient and blood insufficiency(營血不足). Method : I will try to describe the Sanghanlun's Reverting yin disease pattern through the Ke-qin's JueyinbingJie(厥陰病解), and I would like to point out that the exact meaning of Reverting yin(厥陰) is connected with Liver's ministerial fire. Result : Ke Qin's JueyinbingJie explained the Reverting yin disease pattern was connected with Liver(肝), and according to Six qi theory(六氣學說) connected with ministerial fire, and according to meridian and Collateral theory(經絡學說) connected with closing referring to inward actions(闔) among the Opening closing and pivot(關闔樞). Conclusion : Ke Qin was recognized that Reverting yin disease pattern have relevance to the loss of Liver's function. In other world, It is connect with soothe the liver and purge fire(疏肝瀉火) and nutrient and blood insufficiency(營血不足).
