In this paper, we developed an intelligent minimized integrated digital public address which can provide context awareness of various events occurring in future intelligent buildings. It is able to recognize both voices and sounds, such as a fire bell and a disaster bell, which signal to escape in emergence situations and it can sense information which is sent from various sensors, for example, the inner temperature, humidity, and environment status in an intelligent building. Also, the intelligent digital integrated public address can broadcast information to individual places, according to context awareness that is from sensing information, by using network with an ID. And we are developing a minimized integrated digital public address system that has facilities such as external input, Mic., CD, MP3 and Radio. Developing an integrated digital public address system with operational MICOM will make it possible to control the facilities of digital devices centrally. The operational MICOM is composed of 3 layers which are a control layer, a processing layer and a user interface layer.

In this study, we analyzed the perceptions of elementary school students about science learning and lab safety in the affective, behavioral, and cognitive domains. With respect to science learning, students indicated liking science classes more than average, being good at scientific inquiry more than average, and having more scientific knowledge than average. Compared with before the COVID-19 pandemic, student confidence in retaining scientific knowledge had decreased markedly. Of the eight student types in the students' awareness levels about affective·behavioral·cognitive domain, the HHH type-the most ideal-was also the most distributed. Students' preferred science class methods were experimental (72.7%) and nature inquiry classes (23.2%); science knowledge classes were ranked a distant third (4.1%). Preferred class locations were the science lab (58.1%) and different places from time to time (34.4%); the classroom was ranked last (7.5%). With respect to lab safety, most elementary school students did not have experimental classes, but more than half reported understanding how to use experimental equipment. Most students recognized the need to wear safety equipment in the lab. They were not only well aware of the associated physical protection functions, but also of the affective and psychological effects. Most students also recognized that first aid education is necessary, but only 31.5% reported understanding first aid methods. Based on those results, the implications for science learning and lab safety in school are discussed.

Purpose: This study conducted research on the sharing of information to enhance the survival rate of emergency patients by swiftly transferring them to appropriate hospitals through sharing the patients' conditions, treatment histories, and transportation information with the Maritime Police Agency and relevant agencies when emergencies occur in the marine environment. Methods: In this study, emergency patient information classified in a smartphone app was received, stored, and transmitted using the LoRa communication method by electronic triage tags, and the transmitted emergency patient information was implemented to be collected in real-time through a hybrid triage system along with LoRa receivers. Results: Through the hybrid triage system, it was possible to receive emergency patient information according to the distance or confirm delayed reception. It was observed that most data were received when the distance was short, while data reception was unsuccessful in relatively longer distances. Conclusion: It was confirmed that in mass disaster environments where internet communication is impossible, rapid and accurate understanding of casualty information at disaster sites and appropriate disaster responses can be achieved using self-networking methods such as LoRa communication. However, limitations inherent in communication methods were also recognized. Further research on various communication methods is required to collect emergency patient information and transfer them to appropriate hospitals in situations where internet communication is unavailable.

The purpose of this study is to build a bioethical foundation for Paramedic students by identifying and explaining the subjective types and structures of the students' perception on abortion using Q-methodology. Forty statements as a Q sample are selected from the literature and in-depth interview, and P-sample consists of twenty nine junior Paramedic students. The collected data is analyzed by using a QUANL program. The analysis identified three types of the paramedic students' perception on abortion: The fetus-oriented decision type, The mother-oriented active decision type(n=15), The Type(n=9),and mother-oriented passive decision type(n=5). The three factors all had eigenvalues greater than 1.0 and explained 61.3% of the variance in responses. Based on the result of this research, type 1 focuses on the importance of life, whereas other types seem to demonstrate a self-centered mindse that puts more importance on self than the fetus. Therefore, bioethics courses, especially ones that deal with abortion, are crucial to those paramedic students who handle the lives of others.

This paper proposes a method to detect fall action by using stereo images to recognize emergency situation. It uses 3D information to extract the visual information for learning and testing. It uses HMM(Hidden Markov Model) as a recognition algorithm. The proposed system extracts background images from two camera images. It extracts a moving object from input video sequence by using the difference between input image and background image. After that, it finds the bounding rectangle of the moving object and extracts 3D information by using calibration data of the two cameras. We experimented to the recognition rate of fall action with the variation of rectangle width and height and that of 3D location of the rectangle center point. Experimental results show that the variation of 3D location of the center point achieves the higher recognition rate than the variation of width and height.

유비쿼터스 컴퓨팅 환경으로 변화됨에 따라 사용자의 묵시적인 행위에 따라 반응하면서도 주의를 지나치게 집중시키지 않는 다양한 디스플레이에 대한 요구가 증가되고 있다. 본 논문에서는 액자형 앰비언트 디스플레이 시스템을 이용하여 사용자의 위치에 따라 사진을 내비게이션 하는 방법을 제안한다. RFID 센서와 초음파 센서를 이용하여 사용자 신원 및 디스플레이와의 접근거리를 인식하고, 사용자와 디스플레이의 근접도에 따라 보여 질 영상과 인터페이스의 상세도 레벨을 자동으로 정하게 된다. 사용자가 디스플레이로부터 아주 멀리 있는 경우에는 주의를 집중시키지 않도록 단순한 그림 액자의 기능을 제공한다. 사용자가 인터랙션 가능한 영역으로 진입하면 사용자와 관련된 사진을 보여주고, 사용자의 위치에 따라 TIP(Tour Into the Picture) 방법을 이용하여 사진을 3 차원 내비게이션 할 수 있도록 하였다. 또한 터치 스크린을 이용한 메뉴의 직접적인 조작과 공중 마우스를 이용한 원격 메뉴 조작 또한 가능하도록 하였다. 뿐만 아니라 댁내의 응급 상황 정보 등을 전달 할 수 있도록 디스플레이 프레임 주위를 LED 를 이용하여 반짝일 수 있도록 설계 하였다.

This paper aims to propose an emergency recognition system using multimodal information extracted by an image processing module, a voice processing module, and a gravity sensor processing module. Each processing module detects predefined events such as moving, stopping, fainting, and transfer them to the multimodal integration module. Multimodal integration module recognizes emergency situation by using the transferred events and rechecks it by asking the user some question and recognizing the answer. The experiment was conducted for a faint motion in the living room and bathroom. The results of the experiment show that the proposed system is robust than previous methods and effectively recognizes emergency situations at various situations.

최근 들어 국가질병관리체계 현대화가 세계 각국 정부의 중요한 과제가 되고 있다. 캐나다 연방정부는 감염병과 만성질환을 관리하고 생물테러 등 응급상황에 효과적으로 대처하기 위하여 새로운 질병관리조직인 Public Health Agency를 창설하기로 결정하였다. 연방정부는 앞으로 2년간 1,412억원을 투입하여 Agency를 설립하고 사업기반을 확충해 나갈 예정이다(Health Canada, 2004). 또 EU 집행위원회도 지난 3월 European Center for Disease Prevention and Control 설립계획을 최종 승인하고 ECDC가 발족하는 내년 한 해에만 71억원을 투입할 예정이다(Bosch, 2004). 이렇듯 새로운 질병관리조직들이 만들어지고 있는 직접적인 계기는, 중증급성호흡기증후군(이하 SARS) 사태로 대변되는 신종 및 재출현 전염병의 폭발적 발생(outbreak)이다. 전염병의 만연 사태가 일어나면서 각국 정부는 국민건강 보호의 중요성을 재확인하는 한편, 질병으로 인한 경제적 손실을 현실적 문제로 인식하게 되었다. 비전염성질환과 손상으로 인한 질병부담도 세계 각국의 골칫거리다. 서구 여러 나라에서는 비전염성질환과 손상의 질병부담이 이미 매우 큰 상태이며, 저개발 국가들은 전염병과 비전염성질환으로 인한 "이중의 질병부담(double burden of disease)"을 안고 있다고 한다. (중략)고 한다. (중략)

This study was to investigate the current educational situation for Basic Life Support (BLS) and perception on CPR related emergency situation and its relationship with basic nursing skill among undergraduate nursing students in Korea. Participants consider help from others are the most important elements in CPR situation, followed by the skills and knowledge. The majority of the subjects (79.7%) selected high and very high for the association between basic nursing skill and CPR management. The well systematized skill training may ultimately improve students' the ability to react on real-life accidents using well developed emergency management skills.
