This study aims to propose an effective user experience of online class in the non-face-to-face through case analysis, focusing on school-linked education programs with art museums for elementary classes. To analysis domestic and international cases of school-liked education programs with art museum and to measure user experience, we were conducted with task test, in-depth interviews and surveys with experts. As a result, there were the pros and cons about the programs. Based on this, we propose a better method to increase the satisfaction of user experience for children. This study is significant in activating digital technology-based online education. This study expected to used as data on the user experience of a non-face-to-face online art education program in elementary schools in the future.

In this study, an e-portfolio system was constructed and utilized to communicate with students, while processing the overall procedure of teaching-learning activities as data for qualitative improvement in the non-face-to-face educational environment. The e-portfolio system was designed to support the entire process of reflection from the instructor's lesson planning, regular checking of the learner's understanding during the course operation process, online communication, and support for learner-centered educational activities. Analyzing the effectiveness of the communication-based learning effect between instructors and learners using the e-portfolio in liberal arts programming classes, which may be difficult for non-major students, a significant correlation was found in problem-solving skills, and midterm and final exams. Additionally, the result of analyzing the expanded applicability of e-portfolio satisfaction demonstrated a significant correlation with the students' computational thinking ability, test results, assignments, and academic performance. It was found to have a significant effect on the improvement of computational thinking ability. If non-face-to-face education is conducted using the proposed e-portfolio system type, it will be possible to improve the quality of online education, while communicating effectively with students.

COVID-19 팬데믹으로 인하여, 재택근무와 같은 비대면 업무환경이 확대됨에 따라, 기업에서는 내부 보안을 위한 VPN 구축 및 사용률이 급격하게 증가하였다. 하지만, 기존의 대면 환경과는 다르게, 비대면 업무환경에서는 자신을 식별할 수 있는 수단을 제한적으로 활용하기 때문에, 사용자의 비밀번호가 노출되면, VPN에 접근하기 위한 사용자 인증이 무력화되는 심각한 문제점이 존재하며, 이러한 보안 취약점을 해결하기 위한 기술이 요구되는 실정이다. 따라서 본 논문에서는 기존 VPN 인증 기술에 내재된 보안 취약점을 해결하기 위하여, 사물 환경 인증, HIP 기술, 위치 인증, 상호 인증 기술을 활용한 다중 인증 기반의 제로 트러스트를 제공하는 VPN 인증 기술을 제안한다. 최종적으로는 본 논문에서 제안하는 기술을 통하여, 보다 안전성이 향상된 VPN을 제공할 것으로 사료된다.

The purpose of this study was to identify the predictors of self-regulated learning strategies among nursing university students. Data were collected from 212 nursing university students in G metropolitan city and K city. The SPSS WIN 23.0 version program was used for data analysis. The data were analyzed using Pearson's correlation coefficient and multiple regression. There were significant correlations between media multitasking and self-regulated learning strategies(r=.45, p<.001), learning flow and self-regulated learning strategies(r=.59, p<.001), and media multitasking and learning flow(r=.32, p<.001). Friendship satisfaction, media multitasking and learning flow explained 45% of the variance for self-regulated learning strategies. To increase the self-regulated learning strategies among nursing university students, it is necessary to develop multiple interventions that enhance friendship satisfaction, media multitasking and learning flow.

According to the economic advancement, the position of service industry in GDP has increased. Development of service industry has solved the employment issue and derived the activation of the internal market. It has contributed to demand creation in health care, education, and culture, enhancing competition of the manufacturing industry and entire economic development. By the development of information communication technologies, improvement of the quality of life from those, and changes in the competitive environment, customers, from businesses and public agencies, or the customer's needs are increasing. In these circumstances, companies are operating non-face-to-face contact call center for the purpose to communicate with customers, handle customer complaints, attract and retain new customers. In this study, to improve the performance of the non-face-to-face contact call center, this study tried to derive the call center's 'Service Process Modeling' and future policy assignment by analyzing the problem from the research of the service and process summary, performance evaluation, call center evaluation and etc.

In this study, we examine the cases of instructors who conducted subject management by understanding the learning patterns of convergence major students taking programming courses Therefore, we intend to find implications for the operation of SW curriculum for convergence majors in the future. In the programming class of the convergence major, students of various grades and majors take the course, and a survey was conducted to understand their learning patterns in a non-face-to-face environment. The instructor studied whether it would be possible to induce learners' participation in class even when face-to-face communication was not possible, and tried to operate the class by understanding the learning propensity of the learners. As there are many students who have maintained successful experiences in self-directed learning amid COVID-19, weekly assignments were set so that they could solve their own problems independently, and almost all students submitted assignments. This study is meaningful in that it studied students' learning patterns, task performance, and programming achievement by operating 'Machine Learning' subject to students of the convergence major in a non-face-to-face situation due to COVID-19.

비대면 강의가 늘어남에 따라 이에 집중하지 못하는 학습자들에게 강의에 집중할 수 있는 환경을 제공하고자 이 작품을 고안했다. 이 작품은 학습하는 사용자의 모습을 웹캠을 통해 실시간으로 관찰하여 얼굴인식을 통해 학습지가 누구인지 파악하고, 졸음이 감지되거나 화면이 아닌 다른 곳을 응시했을 때 사용자에게 화면상으로 경고 메시지를 보여줌으로써 집중할 수 있게 도움을 줄 수 있는 작품이다. 졸음의 판단 근거는 눈을 감고 있는 것으로 판단하고, 다른 곳을 응시하는 경우에는 화면 상의 동공의 위치 좌표가 눈에서 한쪽으로 치우치는 경우를 판단한다. 작품을 구현하기 위해 python 언어와 라이브러리들을 사용했다. face-recognition library를 이용해 얼굴을 인식했고 dlib library를 이용해 얼굴에서 눈의 landmark를 검출해 학습자가 화면에 집중하고 있는지 파악했다.

코로나 바이러스-19 감염증 상황이 지속됨에 따라 영유아 비대면 상담이 증가하였다. 비대면이라는 제한된 환경에서, 보다 정확한 상담을 위해 영유아의 감정을 예측하는 보조도구로써 CNN 학습모델을 이용한 감정분석 결과를 활용할 수 있다. 하지만, 대부분의 감정분석 CNN 모델은 성인 데이터를 위주로 학습이 진행되므로 영유아의 감정인식률은 상대적으로 낮다. 본 논문에서는 영유아와 청소년 데이터의 감정분석 정확도 차이의 원인을 XAI 기법 중 하나인 LIME을 사용해 시각화하여 분석하고, 분석 결과를 근거로 영유아 데이터에 대한 감정인식 성능을 향상시킬 수 있는 방법을 제안한다.

The purpose of this study is to analyze Korean college students' perceptions of interactions and senses of community, among students, and instructors and students as they took face-to-face classes by the time students and instructors came back to the classroom. Forty-nine college students participated in the study, and all of them had experienced non-face-to-face classes during the last two years from 2020 through 2021. They responded to the revised Rovai (2002)'s Classroom Community Scale (CCS), and the data were analyzed using a frequency analysis. The findings of data analysis showed that the students positively perceived the class contents and teaching formats of face-to-face classes, in terms of understanding and concentration on the class. On the other hand, it was found out that the students would still need more time for being familiar with face-to-face classes, and their affective variables of the educational environment should be considered.
