본 연구는 건설사업장 응급처치 교육실태 및 필요도를 파악하여 응급처치 교육 전파를 위한 기초자료를 제공하는데 그 목적이 있으며, 각 지역에 15개의 건설현장에 종사하는 관계자 총 73명을 선정하였다. 응급처치 교육 필요도와 교육에 따른 대응능력 차이를 알아보기 위하여 빈도분석 및 t-test 검증을 실시하였고 유의수준은 p〈0.05로 하였다. 연구 결과 다른 업종보다 응급사고에 따른 재해발생률이 높은 직군에도 불구하고 응급처치 교육 기회 부족으로 적절한 교육을 제공받지 못하고 있는 것으로 나타났다. 또한 연 2회 이상 응급처치 교육을 희망하고 있었고 최근 응급처치 교육을 이수한 관계자들도 본인의 응급처치 대응 능력이 낮다 라고 응답하여 심폐소생술과, 골절처치와 같은 재교육을 희망하는 것으로 나타났다. 안전사고 예방과 사고 후 응급처치를 효과적으로 현장에 적용할 수 있도록 보다 적극적인 교육 기회를 제공하여야 된다고 생각한다. The purpose of this study is to examine the status and necessity of first aid education in the construction workplace and provide fundamental data to spread first aid education. As subjects, total 73 laborers working at 15 construction sites located in different regions were chosen. To examine the necessity of first aid education and their coping skills acquired through education, frequency analysis and the t-test were done. The significant level is set up as p〈0.05. According to the results, they fail to get proper education for first aid although they are exposed to more disaster resulted from emergency than in other industries. Also, they hope to receive first aid education over twice a year, and even those who have completed first aid education lately also say their first aid coping skills are poor. They want to be retrained about CPR or fracture treatment. Based on the results, this author concludes that it will be needed to provide more positive opportunities for education so that they can apply their first aid coping skills effectively when any accident occurs and also prevent safety-related incidents.

Background and Objectives:The purpose of this study is to find features in acoustics and to learn useful features of parameters in order to distinguish laryngeal diseases through many acoustic variables. Materials and Methods:The subjects of this study were 125-male patients who had been diagnosed with vocal nodule, vocal polyp, vocal cyst, Reinke's edema, leukoplakia. To research the features of each disease in acoustics, they are measured 34 parameters by using MDVP. Results:It is clear that in order to see a meaning result when distinguishing laryngeal diseases, $F_0$, $MF_0$, $T_0$, Fhi, Flo, PER variables are significant (p<.05). It means that variables related to fundamental frequency are important to anticipate which group will be diagnosed with Reinke's edema and leukoplakia. vAm had an effect on getting a significant result in terms of amplitude perturbation parameters, which is useful to distinguish between laryngeal polyp/cyst and other laryngeal disease (p<.05). ATRI made a significant result in related to tremor parameters, which is useful to distinguish between laryngeal polyp and other laryngeal disease (p<.05). Conclusion:$F_0$, $MF_0$, $T_0$, Fhi, Flo, PER, vAm, ATRI might be meaningful parameters distinguishing pathologic from benign laryngeal diseases. Especially, the vAm and ATRI are an important factor when forecasting which group would be diagnosed with vocal polyp.

서구화된 식습관에 따라 현대사회는 급성 심정지로 인한 사망이 높아지고 있으며 그 중요성은 커지고 있다. 2015년 일반인 대상 BLS(Basic Life Support)교육 횟수는 81,435건으로 많은 인원이 소방을 통해 교육을 배우는 것으로 나타났다.그러나 교육에도 불구하고 자동심장충격기에 대한 일반인의 활용 빈도는 저조한 실정이다.본 연구는 선행 연구를 통해 문제점으로 나타났던 자동심장충격기의 사용 의향을 저해하는 구체적인 요소들을 탐색하여 연구에 반영하였으며,고등학생들에게 개선된 BLS교육을 적용하여 궁극적으로 자동심장충격기의 사용 의향을 높이기 위함이다.연구 결과로 대상자 119명 중 기존 자동심장충격기의 사용 의향이 없던 대상자는 62명(52.1%)이었으나 개선된 BLS교육 후 13명(10.9%)으로 감소하였다.자동심장충격기의 사용 의향을 높이기 위한 구체적 방안으로 교육 전에는 자동심장충격기의 사용방법에 대한 교육을 가장 필요로 하였으나 개선된 BLS교육 후에는 자동심장충격기가 있는 장소에 대한 인지의 필요성이 큰 것으로 나타났다.위 결과들을 토대로 일반인들에게 자동심장충격기 사용을 향상시키기 위해서는 사용 방법에 대한 교육이 무엇보다 중요하겠으며,더불어 우리 주변 자동심장충격기가 어디에 위치하고 있는지에 대한 장소의 인지에 대한 교육이 함께 이루어져야 하겠다. Followed by westernized eating habits, in the modern society, there have been more death due to sudden cardiac arrest And the importance of BLS(basic life Support) is increasing. In 2015, the number of BLS education for ordinary citizens was 81,435 and many of them have taken training conducted by fire-fighters. However, despite of those trainings, not many people Are using automated external defibrillators. The present research examines specific factors hampering the usage of automated External defibrillators, which was pointed out as the issue from preceding studies, with the purpose to ultimately increase the Usage of automated external defibrillators by applying improved BLS education to high school students. As a result, 62(52.1%) participants among total of 119 participants had no intention to use automated external defibrillators but after receiving the improved BLS education, the number was decreased to 13(10.9%). As a specific measure to increase intention to use automated external defibrillators, educating how to usage the automated external defibrillators was needed the most before the education but after receiving the improved BLS education, it was highly required to let people recognize the location of the automated external defibrillators. The above research results indicate that learning the usage is the most important education to promote using automated external defibrillators and furthermore, educating the location of the automated external defibrillators should be accompanied as well.

Electric power utilities are facing increasing uncertainties regarding the economic, political, societal, environmental constraints under they operate and plan their future systems. The utilities have to integrate consumers' interruption cost representing reliability worth of electricity into the process of determining the optimum investment level. In order to do so, the estimated outage cost must be included into quantitative index corresponding to system capital and operation investment cost to establish an optimal expansion plan. This paper is a study on the outage cost assessment by using macro approach for calculating IEAR(Interrupted Energy Assessment Rates) and the TRELSS(Transmission Reliability Evaluation for Large-Scale Systems) program was used to calculate EENS(Expected Energy Not Served).

본 논문에서는 포터블 뇌파 바이오피드백시스템을 위한 전치증폭부 및 디지털 신호처리부의 하드웨어 구현에 대한 연구를 수행하였다. 뇌파의 특성을 고려하여 외부 잡음을 제거할 수 있는 뇌파 획득용 전치증폭부를 구현하였다. 측정된 뇌파에는 안전도, 근전도, 심전도 등의 신호들이 포함되어 있으며 이들은 뇌파 분석에 방해가 된다. 따라서 이러한 신호들을 제거하기 위하여 적응여파기 알고리듬을 수행하고 전치증폭부를 실시간으로 구동하는 디지털신호처리부를 구현하였다. 시뮬레이션 파형과 실제 뇌파를 적용한 실험결과를 통하여 개발된 시스템의 성능을 확인할 수 있었으며 휴대형 뇌파 바이오피드백 시스템에 적용 가능함을 확인하였다. In this study, we carried out a study for implementation of the pre-amplifier and the digital signal processing part for the potable EEG biofeedback system. As we consider characteristics of the EEG signal, we designed the pre-amplifier to obtain the EEG signal to be reduced noise signal. Because the EEG signal include EOG, EMG, ECG signals etc, it is difficult to analyze of the EEG signal. Therefore, we developed DSP board and operation program which was embed the LMS adaptive filter algorithm and operate with the pre-amplifier in the real time. The simulation signal and pure EEG signal is used in the experiment. As the result, we confirmed good efficiency of developed system and possibility of application to the portable EEG biofeedback system.

4채널 전두엽 뇌전도에서 안전도 제거 방법의 제안

박정제,조진호,김명남 한국뇌학회 2002 한국뇌학회지 Vol.2 No.2

뇌전도를 전두엽에서 잡파없이 기록할 수 있다면, 심리적 안정을 유도하는 바이오피드백 시스템의 평가에 있어서 장점을 갖는다. 그러나 전두엽에 부착된 전극으로부터 획득된 뇌전도에는 신호처리 및 분석에 방해가 되는 안전도 및 근전도 등의 간섭 신호에 의하여 오염된다. 따라서 본 논문에서는 고차 통계학 기반의 JADE 알고리즘을 이용하여 안전도를 제거함으로써 순수한 뇌전도를 추정하는 방법을 제안하였다. 또한, 전극의 움직임 등으로 인하여 발생하는 임펄스 잡음이 JADE 알고리즘의 성능에 많은 영향을 준다는 점을 확인하고 이를 방지하기 위하여 피크 형태의 잡음을 제거하는 전처리 과정도 제안하였다. 전극은 4개의 채널로 구성하여 여러 가지 배치 방법을 제안하였으며 이에 따른 파형을 나타내었다. 측정 신호에 제안한 방법들을 적용하여 생성된 독립성분들 중에서 순수 뇌전도 성분들 선택하기 위하여 전체 신호에 대한 알파파의 비를 측정하고 그 값이 가장 큰 독립 성분을 뇌전도로 추정하였다. If we can acquire pure EEG signal in the frontal lobe without any noise, there are advantages in the evaluation of biofeedback system that motivate psychological stability. EEG that are acquired from the electrode attaching on the frontal lobe are contaminated by the interference signal of EOG and EMG etc. that are disturbed signal processing and analysis. Therefore, in this paper, we proposed a method to estimate pure EEG using a JADE algorithm based on high order statistics. AND we confirmed that impulse noises decrease performance of JADE algorithm by motion of electrode, so, to prevent this, we proposed a preprocessing methods removing peak noises. Electrodes were composed to four channels and proposed arrangement methods, and we displayed waveform using this. To select pure EEG among independent components that are applied to the proposed method in measured signals, we measured a alpha wave's ratio about whole signal and selected the independent component of the largest alpha wave's ratio.
