해양 수색구조 시나리오 수립 시 익수자 생존시간은 의사 결정을 하는 데 있어 중요한 고려 사항이다. 이 연구에서는 국내 보도자료와 설문조사 및 해외 생존모델을 참고하여 수색자원을 신속하고 집중적으로 투입해야하는 집중 수색기간과 생존 가능성을 고려하여 수색을 유지해야하는 추천 수색시간을 정할 때 참고할만한 익수자 생존시간 지표를 개발하였다.

Purpose The purpose of this study was not only to explore the factors associated with the survival of OHCA(Out-of-hospital Cardiac Arrest), but to provide ideas for improving the operation of emergency medical system in Korea. Method 90,734 OHCAs(Out-of-hospital Cardiac Arrest) with a cardiac etiology, who had been transported by 119 EMS ambulances for seven years from 2006 to 2012 in Korea, were analyzed. The data had a multilevel structure in that patient's survival in the same region is interrelated, so two-level (patient-region) logistic regression analysis was applied to adjust this correlation. Results The adjusted OR in group who were given CPR(Cardiopulmonary Resuscitation) by a bystander were 1.40 for survival to discharge. In addition, the adjusted OR in the group with an implementation of AED (automated external defibrillator) before arriving in hospital was 2.98 for survival to discharge. we categorized some continuous variables (number of emergency physician, OHCAs volume fo hospital, area deprivation level) into five quintiles. The adjusted OR in the number of emergency physician compared with Q1(lowest) was 1.29(Q2), 2.89(Q3), 3.39(Q4), 4.07(Q5), respectively. the adjusted OR in OHCAs volume of each hospital compared with Q1(lowest) was 2.06(Q2), 3.06(Q3), 3.46(Q4), 4.36(Q5), respectively. Lastly, the adjusted OR in deprivation level compared with Q1(least deprived area) was 0.72(Q4), 0.64(Q5) so that the adjusted OR of survival to discharge tended to decrease in more deprived districts. Conclusion The survival to discharge was better significantly in group given CPR by a bystander and with the implementation of AED before arriving in hospital. The survival to discharge tended to be significantly better in hospitals with a larger number of emergency physicians and higher volume of OHCAs in less deprived districts.

브로일러 계군에서 질병으로 인한 피해를 파악하는데는 어느 분야보다도 자료의 부족을 절감하게 된다. 필자가 파악하기로는 몇개 사료회사에서 사료의 질을 파악하는 방편의 일환으로 생존율을 조사하고 있으나 자료를 얻기가 쉽지 않고 또한 자료를 구한다 치더라도 조사대상 농장의 전반적인 사양관리상의 수준 등을 고려할 때 그것이 국내에서의 브로일러의 생존율을 대표하기보다 왜곡된 자료일 가능성이 많다. 그래도 유일하게 신빙성이 있는 자료는 가축위생연구소와 대학에서 실시하고 있는 가금질병 진단써비스 자료이다. (중략)

In this study, using the job history data of the Youth Panel(1-12th year: 2007 ~ 2018) of the Korea Employment Information Service, it is found that characteristics and duration distribution of first jobs of wage and salary worker, and estimated the factors of first job exit by utilizing survival analysis. As a result of the analysis, regular workers are less likely to leave their first jobs than temporary/daily workers. In addition, the group with a high degree of major congruence was found to have a lower chance of leaving the first job than the group with a major mismatch. And the higher the income level, the lower the probability of departure, which shows that the possibility of leaving low-income workers is very high.

This paper proposes a framework to determine the routes of multiple unmanned aerial vehicles (UAVs) to conduct multiple tasks in different locations considering the survivability of the vehicles. The routing problem can be formulated as the vehicle routing problem (VRP) with different cost matrices representing the trade-off between the safety of the UAVs and the mission completion time. The threat level for a UAV at a certain location was modeled considering the detection probability and the shoot-down probability. The minimal-cost path connecting two locations considering the threat level and the flight distance was obtained using the Dijkstra algorithm in hexagonal cells. A case study for determining the optimal routes for a persistent multi-UAVs surveillance and reconnaissance missions given multiple enemy bases was conducted and its results were discussed.

공정기술의 발달과 컴퓨터 구조적인 발전에 의해서, 시스템의 동작속도가 기하급수적으로 증가하고 있다. 동작속도의 증가는 CMOS로 구현된 chip의 RC 특성에 의해서 timing variation 문제가 발생할 가능성이 높아지면서 테스트 비용이 전체 설계비용에서 차지하게 되는 비중이 급격하게 증가하고 있다. 따라서 온라인 테스트와 진화하드웨어 등이 테스트 비용감소를 위해서 연구되고 있다. 본 논문에서는 네트워크프로세서의 생존성을 위해서, 패킷엔진의 pipline의 각 stage사이의 clock slack borrowing을 이용해서 timing variation 문제를 자체적으로 해결할 수 있다는 것을 mixed-mode simulation을 통해서 통합 검증하였다. 또한 기존의 off-chip 진화하드웨어에 비해서 on-chip구현을 통해서 진화하드웨어의 성능향상과 메모리에 의해서 발생하는 overhead를 감소시키는 것이 가능함을 확인했다.

The cardiac anatomic position immediately beneath the sternum leaves it vulnerable to injury when this bone is fractured. Cardiac rupture, however, is uncommon but survival following this injury is rare. We report the case of one patient who survived right ventricle perforation resulting from sternal fracture. The patient developed signs of pericardial tamponade and was brought to the operating theatre immediately for surgery through the emergency anterolateral thoracotomy Perforation of th right ventricle was repaired by direct closure without cardiopulmonary bypass. We believe that patients with cardiac rupture who reach the hospital alive can often be saved by prompt diagnosis and surgery.

Due to the value and the importance of preservation of disaster web records, to build disaster archives is globally becoming a national challenge. This study proposes a acquisition methods based on the issue life cycle model for collecting disaster web records. We firstly analyzed web records acquisition status, methods and period of domestic and foreign disaster archives. In addition, the issue life cycle model was derived by collecting and analyzing the disaster issues in the last 10 years. As the results of the analysis, the issue life cycle model was divided into the sudden type and periodic type according to the characteristics of the disaster. In conclusion, this study propose a method to collect web records according to each model and verify its applicability.
