Usability study of the CU Medical "i-PAD" AED was conducted to validate the usability of the device, primarily focused on the trained user as well as the utility of the training material. Comparing these results of the trained participants to those obtained by Callejas et al. (2004), who studied video-trained users of two commercially available Philips AEDs (FR2 and HS1) using a male manikin only, the participants in this study were more successful (100% vs. 85.7%-FR2 vs. 88.9%-HS1) and faster to shock (58.5s-i-PADvs. 91s-FR2 vs. 90s- HS1). While the focus of this study was on validating ease of use for trained bystanders, the results of the untrained condition showed that, from a usability perspective, these devices perform as well as any other AEDs already approved and available for purchase for untrained bystander use, as evidenced by the comparison to various published research results

In this paper, we implemented a high performance automated external defibrillator(AED) simulator that has various characteristics of virtual simulated patient(VSP) to verify important operations and functions of the AED. To verify the AED in various environment, the AED simulator should have the characteristics of VSP and can analyze the characteristics of electrical shock rhythm. In this paper, the implemented simulator has twenty seven electrocardiogram scenarios and we showed the implemented simulator has less error rate than conventional simulator in analyzing electrical shock rhythm.

This study aims to examine the relative importance of various tasks of EMT and to examine knowledge level and problems associated with AED. It is based on the survey of paramedics and 119 rescures. The results for this study were as follows ; Among the tasks of EMT, 'foreignbody removal from mouth' were rated as the most important, followed by '$O_2$ supply', 'CPR', 'Intubation for CPR', '$O_2$ supply' were rates as the most necessary, followed by 'foreignbody removal from mouth', 'external bleeding control'. In terms of the knowledge level about AED, survey respondents are most knowledgeable about 'role of other rescures during the preparation for AED' and 'treatment after 3 AEDS. The most important reason that the uses of AED is delayed is 'unclear boundary of treatment directed by medical control'. The results of the study suggest that we need guideline for EMT's tasks, efficient communication system between 119 and emergency health are center for prompt AED, and training and education program for AED.

현재 국내 인체 이식용 전자 의료기의 이식건수는 매년 약 1800 여건으로 해마다 증가하고 있으며 그 연령대도 다양한 작업환경에 노출되는 청장년층으로 급속히 확대되어 가고 있다. 이러한 이식용 의료기는 인공 심장 박동기, 이식형 제세동기, 진통억제를 위한 이식형 전기 펄스 발생기, 이식형 약물주입기 등을 포함한다. 그러한 기기들은 미세한 생체 신호에 따라 반응하기 때문에 생체 신호이외의 잡음에 의한 오동작은 절대적으로 피해져야 하며 경우에 따라 생명위협과도 직결된다. 본 논문에서는 현재사용 중인 이식형 전자의료기들의 구조와 동작원리, 다양한 작업 환경 하에서 잡음의 영향을 고찰하고, 잡음에 의한 오동작의 방지 방안을 고찰함으로써 전자의료기 인체 삽입자의 작업환경에 따른 안전문제를 제고하고자 한다.

In designing defibrillator several points must be considered such as patient's transthoracic impedance, output energy level, peak current, tine duration of current waveform. Patient's transthoracic impedance depends on patient respectively and the health condition of patient. In this study, before the hardware implementation of defibrillator we determine the range of parameter values of circuit elements to derive optimal discharge waveform by predicting and analyzing the performance of designed circuit.

본 시스템은 4 차 산업 혁명이 발발한 이점을 살려 가상현실(Augmented Reality)을 활용, 극대화된 시각적인 요소들을 추가하여 사용자들의 흥미를 유발한다. 또한 더욱 정확한 평가 기준을 세우기 위해 사용자의 흉부 압박 빠르기와 깊이를 측정할 수 있는 각종 센서를 활용하였다. 관리자는 신뢰성 있는 데이터를 바탕으로 사용자들을 평가한다. 기존의 평가는 평가자의 눈대중, 직감으로만 평가가 이루어지기에 신빙성 및 신뢰를 하기 어렵다. 따라서 사용자들은 현실감 있고 정량화된 데이터를 바탕으로 정확한 평가 및 피드백을 받을 수 있는 교육, 평가가 절실히 필요하다. 따라서 본 논문에서는 가상현실을 활용한 심폐소생술(CPR) 및 자동 제세동기(AED) 교육 평가 시스템을 제안한다.

The equation based on vector inner product by the angles between pairs of two image rays can independently separate the position and pose of a camera. As our second application, the exterior calibration between a camera and a laser range finder is proposed here through analysis of surfaces created by the equation.

관세법에서는 해외직구물품이 일정금액(미화 150불, 단 미국은 미화 200불)이하 또는 자기사용 물품으로 인정되는 경우에 제세를 면제토록 규정하고 있으며 관련규정을 어길시 관세법상 무신고 밀수입죄에 해당된다. 본 논문은 해외직구 리셀러(되팔이)가 증가하고 해당 사항이 사회적 이슈로 대두되기에 해외직구 물품 불법거래에 관한 모니터링시스템을 설계하고 해석하였다. 온라인 중고 사이트(e-commerce)에서 거래되고 있는 거래 내용을 크롤링을 통하여 데이터를 수집·전처리를 통해 구조화하고 데이터 정제, 텍스트 범주화, 텍스트 마이닝 등 관계 예측을 해석하였다.
