This study was conducted to investigate experiences, convergent responses and expected negative impacts of verbal abuse of 253 paramedic students when they were doing clinical training practice. The results were as follows. First, 34%(86 people) experienced verbal abuse, the most frequently verbal abuse was done by Patients and Patient's family. Second, the most frequently contents of verbal abuse by Patient and Patient's family, Paramedic, Doctor and Nurse was 'Talking down or rude talk to me'. Third, the most frequently emotional responses of the students was 'Angry' and coping was 'Tolerate'. Fourth, the most frequently expected negative impacts was 'Practice productivity will be compromised'. Fifth, when experiencing verbal abuse by Paramedic was correlated with emotional responses(r=.458 p=.000), emotional responses was correlated with stress and expected negative impacts(r=.553 p=.000, r=.540 p=.000). In conclusion, it will be necessary to provide preventive education on verbal abuse before clinical training practice and to take active measures that have been protocolized.

Multimodal medical image fusion (MMIF) fuses two images containing different structural details generated in two different modes into a comprehensive image with saturated information, which can help doctors improve the accuracy of observation and treatment of patients' diseases. Therefore, a method based on double-layer decomposer and fine structure preservation model is proposed. Firstly, a double-layer decomposer is applied to decompose the source images into the energy layers and structure layers, which can preserve details well. Secondly, The structure layer is processed by combining the structure tensor operator (STO) and max-abs. As for the energy layers, a fine structure preservation model is proposed to guide the fusion, further improving the image quality. Finally, the fused image can be achieved by performing an addition operation between the two sub-fused images formed through the fusion rules. Experiments manifest that our method has excellent performance compared with several typical fusion methods.

This study seeks to measure inter-industry convergence systematically and quantitatively using structural holes theory. ICT industries were classified into ICT manufacturing and ICT service then efficiency and constraints were calculated using input-output tables. The results of the study revealed both ICT industries have very high information and control benefits in the process of industrial convergence, proving to be key industries with competitive advantage. Further implications were presented based on comparative analysis between ICT manufacturing and service and trend analysis over the past 15 years.

This study surveyed the convergence of organizational culture, organizational structure, emotional labor on job satisfaction of dental workers and analyzed it with SPSS WIN18.0 program to obtain statistically significant results(p<.05). Organizational culture was high men, dental hygienist, university graduates, hospitals, many workers, High income. Organization structure was high hospitals, many workers. Emotional labor was high low age and career, single, drinking. Job satisfaction was high more than 10 workers, high income. There was a positive correlation between job satisfaction, organizational culture, organizational structure. The regression analysis showed that Y (job satisfaction) = .907 + .106 (organizational structure). Therefore, in order to enhance job satisfaction of dental workers, it is necessary to make an effort to form a positive organizational culture by considering variables related to organizational structure.

Interdisciplinary convergence research is widely seen as a collaborative research between different disciplines, which is often driven by common agenda or problems in pursuit of a particular common objective. Thus, the purpose of interdisciplinary cooperation in convergence research is to bring each discipline's unique perspective together with the academic expertise of researchers in order to share common problems that cannot be solved effectively without research partnership. We present empirical evidence on how interdisciplinary research relationships are formed to facilitate research networking in convergence relations. In particular, we used network analysis to investigate how interdisciplinary linkages and convergence research networks has formed over time. We found that the convergence research networks were implemented by the interdisciplinary convergence research support program as intended. We did find that research field with high indegree and outdegree in a network played critical roles on the dynamics and degree of interdisciplinarity. Finally, we could find evidence that the role of liaison brokers triggered relational dynamics in interdisciplinary research collaboration.

The purpose of the study is to examine the visual evaluation of bleeding amount in hemorrhagic shock in paramedic students. Through manikin simulation training, paramedic students were able to have confidence with estimation of bleeding amount in the prehospital settings. Three rescue training manikins were placed in supine position and artificial blood was poured between the abdomen and pelvis. The bleeding evaluations of 700 mL, 1200 mL, and 1700 mL were performed before and after simulation training. Paramedic students underestimated the amount of bleeding in the trauma situation, and it was found that it was difficult for the students to evaluate the accurate amount of bleeding with a single simulation.

현재의 메타버스 서비스는 메타버스 학술대회, 메타버스 입학식 등과 같이 단순히 실제 세계의 대체품 역할만을 수행하고 있으며 앞으로의 메타버스는 실제 세계와 가상 세계가 융합된 실·가상 융합형 메타버스 서비스로 발전할 것이다. 실제 세계와 가상 세계가 융합하기 위해서는 실제 세계에 존재하는 다양한 물리적 개체의 정보가 가상 세계로 반영되어야 하며 메타버스 서비스의 규모가 증가함에 따라 높은 확장성을 지원하는 통신 기술이 요구된다. 본 논문에서는 높은 확장성의 통신 미들웨어인 DDS와 시간 확정적 전송을 보장하는 TSN 표준을 융합하여 메타버스 서비스가 요구하는 방대한 데이터를 시간 확정적으로 전송할 수 있는 DDS-TSN 계층 구조를 설계한다.

The purpose of this study is to implement the convergence thinking in problem-based learning (PBL) on paramedic education. PBL scenario course was conducted for 78 students in the third year of emergency medical technology during the first semester of 15 weeks in 2017. After 15 weeks, data of 73 students were analyzed. Among questions about learning interest in PBL, 'neutral' was the most frequent response with 38% for "PBL scenario classes were more effective in learning and acquiring knowledge than lecture class". For "The lessons learned in the class helped to improve the ability to come up with appropriate solutions for problem solving", 57.5% responded 'agree', and for "The lessons learned in the class helped with confidence in the emergency scene", 50.7% responded 'agree'. PBL will be an effective and efficient way of teaching as a learning curriculum for understanding the field situation.

컴퓨터 비전 분야에서 오랫동안 사용되었던 CNN(Convolution Neural Network)은 오분류를 일으키기 위해 악의적으로 추가된 섭동에 매우 취약하다. ViT(Vision Transformer)는 입력 이미지의 전체적인 특징을 탐색하는 어텐션 구조를 적용함으로 CNN의 국소적 특징 탐색보다 특성 픽셀에 섭동을 추가하는 적대적 공격에 강건한 특성을 보이지만 최근 어텐션 구조에 대한 강건성 분석과 다양한 공격 기법의 발달로 보안 취약성 문제가 제기되고 있다. 본 논문은 ViT가 CNN 대비 강건성을 가지는 구조적인 특징을 분석하는 연구와 어텐션 구조에 대한 최신 공격기법을 소개함으로 향후 등장할 ViT 파생 모델의 강건성을 유지하기 위해 중점적으로 다루어야 할 부분이 무엇인지 소개한다.
