Purpose: The aim of this study was to verify the necessity of endotracheal intubation through video laryngoscope and to provide basic data to inform the provision of video laryngoscope education. Methods: Eighty paramedic students participated in this study. A survey was conducted from November 5, 2018 to December 7, 2018. Data were analyzed with independent t-tests, and the chi-squared test. Results: The video laryngoscope is a highly usable instrument that can easily be applied during training. The instrument provides better visual evaluation of the normal airway (p=.004), the airway in case of cervical collar and head fixation (p=.000), and the airway in case of tongue edema (p=.000). The time of endotracheal intubation in the normal airway was significantly less with the video laryngoscope compared with the direct laryngoscope. The success rate of tracheal intubation was significantly higher in the video laryngoscope group than in the direct laryngoscope. Conclusion: This study suggests the necessity of education on endotracheal intubation through video laryngoscope in the professional airway maintenance training course of emergency department students. The video laryngoscope is easier to apply than the direct laryngoscope in cases of intubation in various clinical situations.

본 연구에서는 화상 교육 시스템을 이용하여 사이버 집단 상담을 실시하고 그 효과를 검증하였다. 이를 위해 두 가지 가설을 설정하였다. 첫째, 실시간 화상 사이버 집단 상담은 자기 존중감을 증진 시킬 것이다. 둘째, 화상 교육 시스템을 활용한 사이버 집단상담은 학생들의 내적 행동 변화를 가져올 것이다. 이 두 가설을 검증하기 위해 대도시 D초등학교 학생 45명을 선발하고 이미 개발된 화상 교육 시스템을 이용하여 사이버 집단 상담을 실시하였다. 그 결과 실시간 화상사이버 집단 상담은 학생들의 자기 존중감을 증진시키고 내담자의 적극적인 참여를 유도하며 활발한 상호작용을 일으켜 상담자와 내담자 간에 정서적 안정감 및 친밀감을 형성시키는 것으로 나타났다. 따라서 본 연구의 결과는 집단 상담의 사이버 영역을 한 단계 넓히는 데 도움을 줄 것이며 본격적인 실시간 화상 교육 체제의 시행을 앞두고 다자간 화상시스템의 교육적 효과를 검증하는 연구에 기초 자료로 활용될 것으로 사료된다.

Recently, retrieval or various video data has become an important issue as more and more multimedia content services are being provided. To effectively deal with video data, a semantic-based retrieval scheme that allows for processing diverse user queries and saving them on the database is required. In this regard, this paper proposes a semantic-based video retrieval system that allows the user to search diverse meanings of video data for electrical safetyrelated educational purposes by means of automatic annotation processing. If the user inputs a keyword to search video data for electrical safety-related educational purposes, the mobile agent of the proposed system extracts the features of the video data that are afterwards learned in a continuous manner, and detailed information on electrical safety education is saved on the database. The proposed system is designed to enhance video data retrieval efficiency for electrical safety-related educational purposes.

Objective: The purpose of this study is to identify the effects of sign language video location in e-learning system for the hearing-impaired. Background: E-learning education is a good way to resolve the inequality of education for the disabled. Providing a sign language video in e-learning education for the hearing-impaired is very important for their learning. Although the location of sign language video is an important factor in the design of the video, the effect of its location in learning using the e-learning system was not studied. Method: In order to identify the effect of sign language video location on the learning of the hearing-impaired using the e-learning system, the prototypes of the system with different locations were developed. Eighteen people with hearing impairment participated in this experiment. Learning presence, learning immersion, and learning satisfaction were used to measure learning effects with sign language video location. Results: Bottom right position was more preferred through preference evaluation for sign language video location. The learning effect with sign language video location (bottom-left and bottom-right) was not significant. That is, the effects of learning presence, immersion, and satisfaction were not statistically significant with video location. Conclusion: From this study, the following have to be considered in e-learning system design for the hearing-impaired. Although the location of a sign language video is not a significant factor from the experiment, the bottom right position in the design is proposed because learning presence and satisfaction is slightly higher at the bottom right position, and the position is preferred from subjective evaluation. From the analysis of interview data, it was also proposed that the design of a sign language video should be improved for the hearing-impaired. Application: The result of this study can be applied to the e-learning system design for the hearing-impaired.

초등영어교육이 듣기, 말하기 위주의 음성언어 중심 교육 원칙을 중요시하고 있으나 현재의 학습환경에서는 비디오나 오디오를 따라하는 수준에서 지도되고 있다. 음성언어 중심 영어학습은 ESL환경에서 배우는 것이 가장 효과적이라고 할 수 있다. 따라서 본 논문에서는 학교교육에서 배운 영어를 웹에서 학습할 수 있는 기회를 갖도록 멀티미디어 컨텐츠를 제작하여 제공하도록 하고 있다. 또한 화상회의 시스템이나 전자우편을 통하여 언제든지 다시 사용해 볼 기회를 갖게 함으로써 영어학습에 대한 강화가 실생활에서 일어날 수 있도록 하는 방안에 대해 연구하였다.

Purpose: This study aimed to verify the effects of preoperative video education on delirium and anxiety in elderly patients with general anesthesia. Methods: This study used quasi-experimental research with a non-equivalent control group non-synchronized design. Participants were 70 elderly patients who had undergone of surgery under general anesthesia (35 in the experimental group and 35 in the control group). Preoperative video education was given to the experimental group. Subjective anxiety, blood pressure, pulse and delirium were measured. Data were analyzed using descriptive statistics, test of homogeneity in pretest, independent t-tests, and two-way repeated measures ANOVA with the SPSS/Win 22.0 program. Results: Delirium of the experimental group was significantly lower than that of the control group. Subjective anxiety measured using visual analogue scale was not significantly different between the two groups. However, there was a significant difference in the interaction between the group and time. There was no significant difference in physiological anxiety measured using systolic blood pressure, diastolic blood pressure and pulse between the two groups. Conclusion: The findings suggest that preoperative video education may contribute to reducing delirium and subjective anxiety for elderly patients after surgery.
