        프로젝트형 의사결정학습을 통한 초등학교 독도교육 방안

        전혁진 ( Hyuk Jin Jeon ) 역사교육학회 2014 역사교육논집 Vol.52 No.-

        While focusing on how a homeroom teacher would be in charge of teaching several subjects at a time at elementary school, the concerned study, first, selected the social studies department as a research subject and then, discussed how to teach learners by using a project-type decision-making learning method. This study used the decision-making learning method which would enable the learners to do a social inquiry and a value inquiry when they try to study social studies. When it comes to learning history, decision-making is considered as an investigation- oriented learning method which would lead the learners to make a decision when they try to improve their knowledge on historical facts. This decision-making learning method encourages the learners not only to improve their understanding on historical facts but also to be able to give causal explanations of the historical facts, having this empathic understanding on historical doers. In addition, the concerned learning method is also considered effective to help the learners form historical consciousness, convincing them of social participations. In order to enhance the learners` background knowledge on Dokdo, helping them make reasonable decisions, this study, first, looked into a dispute over Dokdo, investigating opinions of Korea and opinions of Japan. In doing so, the study led the learners to see how Dokdo belongs to Korea including how important it is to let others know about the fact. This project-type decision-making learning method was a chance for the learners to extract academic knowledge via a process of reflective decision-making and observation as they improve their understanding on Dokdo, having even clearer ideas about their own values.

        병원 전 심정지 상황에서 수기 심폐소생술과 X-CPR™를 이용한 심폐소생술의 비교

        전혁진(Jeon, Hyuk-Jin),이인수(Lee, In-Soo),김상철(Kim, Sang-Chul) 한국웰니스학회 2015 한국웰니스학회지 Vol.10 No.2

        본 연구는 수기 심폐소생술과 X-CPRTM를 이용한 심폐소생술을 비교함으로써 병원 전 심정지 상황에서의 더 효과적인 심폐소 생술 방법을 알아보는데 그 목적이 있다. 2인 1조로 구성된 20조에서 각각 10조씩 수기 심폐소생술과 X-CPRTM를 이용한 심폐소 생술을 나누어 현장에서 병원 도착까지의 상황을 시뮬레이션 하였고 총 5.1km의 이송 거리를 가진 상황으로 실험되었다. 연구결 과, 가슴압박에서는 수기 심폐소생술이 47.4±1.3mm로 X-CPRTM를 이용한 심폐소생술보다 약 20mm 더 깊게 시행하는 것으로 나 타났으며 인공호흡에서는 그룹간의 차이를 보이지 않았다. 유효혈류시간에서는 수기 심폐소생술에서 73.7±1.1%, X-CPRTM를 이용 한 심폐소생술에서 66.7±1.3%로 나타났으며 통계적으로 유의한 차이를 보였다. 결론적으로 X-CPRTM를 이용한 심폐소생술은 수기 심폐소생술 보다 더 향상된 심폐소생술을 제공한다고 보기는 어려우며 이를 해결하기 위해 응급의료종사자에게 지속적인 훈련을 시행하고 실질적으로 경험할 수 있도록 해야 한다. 또한 이에 대한 추가적이고 지속적인 연구가 필요할 것이다. The purpose of this study is to investigate the quality of Manual CPR and X-CPRTM in out-of-hospital cardiac arrest situation and to suggest an efficient CPR. There are twenty groups, first ten groups performed only manual CPR in the whole cardiac arrest situation out of a hospital 5.1km away from the site, and second ten groups performed Manual CPR at the situation site and then performed X-CPRTM until a patient was transported to the hospital. With regard to compression depth, the depth of the manual chest compression performed was 47.4±1.3cm, around 2cm deeper than the mechanical chest compression depth??(p<0.01). In respect to artificial respiration, the two types of groups showed no difference. Regarding the rate of valid blood flow time, Manual CPR was 73.7±1.1%, and X-CPRTM was 66.7±1.3% (p=0.001). Given the result, it is hard to see that X-CPRTM provides better quality than manual CPR, and even improper use of X-CPRTM can bring about a lower effect than Manual CPR. Therefore, it is necessary to constantly provide education about the use of the relevant equipment to emergency medical workers and help them experience it practically, thus follow-up studies must be carried out.

        가슴압박소생술에서 수기가슴압박과 능동 가압-감압 장치를 이용한 가슴압박의 질 비교 ; 마네킹 연구

        전혁진(Jeon, Hyuk-Jin),이명렬(Lee, Myung-Lyeol),이인수(Lee, In-Soo),신동민(Shin, Dong-Min) 한국웰니스학회 2015 한국웰니스학회지 Vol.10 No.3

        능동 가압-감압 심폐소생술(ACD-CPR)을 이용한 가슴압박소생술과 hands only CPR을 비교함으로써 더 효과적인 hands only CPR방법을 제시하고자 연구를 시작하였다. 시뮬레이션 상황은 심정지 환자 발견 후 대상자들이 hands only CPR을 10분간 진행하 는 것으로 하였으며 BTInc.(Korea)의 CPR Evaluation Simulator(BT-CPEA)를 사용하여 측정하였고 시뮬레이션 종류 후 설문을 하였 다. 11명의 남자와 9명의 여자가 시뮬레이션에 참여하였으며 hands only CPR에서 약 200회 더 많은 가슴압박을 시행하였으며 정 상 깊이로 시행된 가슴압박 또한 hands only CPR에서 많이 시행하였다. 정확한 위치, 가슴의 완벽한 이완에서도 hands only CPR 이 통계적으로 유의하게 더 많이 이루어지고 있는 것을 확인할 수 있었다. 설문에서는 대부분 ACD-CPR을 사용하였을 때 더 불편 하다고 하였으며 CPR 하는 것도 더 힘들다고 하였다. 따라서 ACD-CPR을 이용하였을 때 기존의 hands only CPR보다 효과적인 가슴압박을 하기는 어려우며 이에 대한 추가적인 연구가 필요하다. Began the study to present a more effective hands only cardiopulmonary resuscitation (CPR) method by comparing hands only CPR using Active Compression-Decompression CPR (ACD-CPR) with hands only CPR which doesn't use this. Simulated situation was set as that subjects are going to perform hands only CPR for 10 minutes after finding the patient of cardiac arrest, measured by using CPR Evaluation Simulator (BT-CPEA) of BTInc. (Korea), and surveyed after completion of simulation. 11 men and 9 women participated in the simulation, and in the hands only CPR were performed about 200 times more, and chest compressions undertaken to normal depth were performed a lot of in hands only CPR. In the exact location, even in complete relaxation of chest found that hands only CPR were performed more significant in statistically. In surveys, most responded that it was more uncomfortable when using ACD-CPR, and performing CPR was also harder. Thus, when using ACD-CPR, to perform Chest compressions more effectively than conventional hands only CPR is difficult , and requires additional study on this.

        NetFPGA를 이용한 고성능 오버레이 멀티캐스트 패킷 전송 엔진 구현

        전혁진(Hyuk-Jin Jeon),이현석(Hyunseok Lee),정용진(Yong-Jin Jeong) 대한전자공학회 2012 電子工學會論文誌-SD (Semiconductor and devices) Vol.49 No.6

        인터넷상에서 고품질 멀티미디어 서비스는 화상회의나 실시간 인터넷 방송 등 여러 분야에 적용 될 수 있기 때문에 주목받고 있다. 이러한 서비스에서 네트워크 자원을 효율적으로 사용하기 위해 IP 멀티캐스트가 해결책으로 제시되고 있지만 관리상의 문제점으로 인해 실제로 사용되지 못하고 있다. 대안으로 기존의 라우터들의 하드웨어를 변경하지 않고 상위계층에서 라우팅을 하는 오버레이 멀티캐스트가 제시되고 있다. 하지만 오버레이 멀티캐스트는 상위계층에서 멀티캐스팅 동작을 수행하기 때문에 최대 전송속도가 낮아서 고속 멀티미디어 데이터 전송에 부적합하다. 본 논문에서는 NetFPGA를 이용하여 고속의 처리가 필요한 부분인 멀티캐스팅 동작을 위한 패킷의 복제와 전송, 터널링 기능을 설계 하였다. 그 외에 비교적 고속의 처리가 필요하지 않은 부분은 소프트웨어로 구현하였다. 이로 인하여 실시간 처리가 가능하도록 하였다. 향후 성능 개선을 통하여 복제 가능한 지점의 수를 늘리고, 최적화를 통해 처리속도를 증가 시킬 연구를 진행할 것이다. High-quality multimedia on the Internet has attracted attention because of its wide application area. IP multicast has been proposed as a solution to use efficient network resources in these services. However, IP multicast has not been commonly used due to a number of practical issues such as security and management. As an alternative, an overlay multicast routing which is performed in upper protocol layers on legacy networks without changing hardware has been presented. Yet, the maximum data transmission capacity of the overlay multicast is not sufficient for real time transmission of multimedia data. In this paper, we have implemented an overlay multicast engine on NetFPGA which allows us to perform packet replication and tunneling which need high-speed. In addition, we have implemented extra portions which need low-speed in software. From now on, we will progress research which increase the number of terminal spots which can be replicated by improvement and amplify throughputs by optimization.

        성강민 ( Kang Min Sung ),김상철 ( Sang Chul Kim ),전혁진 ( Hyuk Jin Jeon ),곽영수 ( Yeong Soo Kwak ),윤영한 ( Young Han Youn ),이강현 ( Kang Hyun Lee ),박종찬 ( Jong Chan Park ),최지훈 ( Ji Hun Choi ) 대한외상학회 2015 大韓外傷學會誌 Vol.28 No.3

        Purpose: To compare injury sustained and severity of child occupant according to the types of safety restraint systems in motor vehicle crashes. Methods: This was a retrospective observational study. The study subjects were child occupants under the age of 8 years who visited a local emergency center following a motor vehicle crash from 2010 to 2014. According to safety restraint: child restraint systems (CRS), belted, and unbelted, we compared injuries sustained and injury severity using the maximal Abbreviated Injury Scale (MAIS) and Injury Severity Score (ISS), and analyzed the characteristics of severe injuries (AIS2+). Results: Among 241 subjects, 9.1% were restrained in CRS, 14.5% were only belted, and 76.3% was unbelted at the time of the crashes. Fourteen had severe injuries (AIS2+), all of whom didn’t be restrained by CRS. Injuries in face and neck were the highest in unbelted group, and MAIS and ISS were the lowest in CRS group. Conclusion: Among safety restraint systems for child occupant in motor vehicle crashes, the CRS have the preventive effect of face and neck injuries, and are the most effective safety restraint systems.

        박상민 ( Sang Min Park ),김상철 ( Sang Chul Kim ),이강현 ( Kang Hyun Lee ),이재완 ( Jae Wan Lee ),전혁진 ( Hyuk Jin Jeon ),김호중 ( Ho Jung Kim ),김진용 ( Jin Yong Kim ),곽영수 ( Young Soo Kwak ),이우성 ( Woo Sung Lee ) 대한외상학회 2014 大韓外傷學會誌 Vol.27 No.3

        Purpose: Rollover motor vehicle crashes have a higher injury severity and fatality than other motor vehicle crash types. From a left-quarter turn rollover accident of 25-passenger bus, we intend to assess the injury of the occupant and the injury severities according to the occupants` position. Methods: We carried out the 3 steps investigation of occupants` interview, visiting the repair shop and using the police report. We analyzed injuries sustained by occupants, and compared injury severities considering column, row in occupant`s position and passenger interaction Results: The rollover involved 14 passengers in the bus who were all old women except a man driver. The most common injury was in the upper extremity, with six occurrences being a left clavicle fracture. Major injuries including hemothorax and pneumothorax were diagnosed at left side of the occupant. In the comparison of injury severity among driver`s column (left side), mid column and passengercolumn, ISS of passenger column was the highest (9. ±7.4, 8.8 ±5.5, and 10.3±4.0, respectively, p>0.05). The injury severity of multiple occupants by row was higher than that of single occupant (10.8 vs. 3, p<0.05). Conclusion: An occupant must fasten their seat belt to prevent an injury by passenger interaction in the left-quarter turn rollover accident of a bus. [ J Trauma Inj 2014;27:50-56 ]
