시대가 변화됨에 따라 다양한 비대면 방송들이 증가하는 추세를 보이고 있다. 가상현실(VR)을 이용한 쇼케이스부터 실시간 쌍방향 소통을 활용한 무대까지 멀티뷰를 활용한 방송들이 여러 방향으로 활용되고 있으며. 이러한 환경 속에 관객과 조금 더 밀접한 방송을 진행하기 위한 여러 방법이 시도되고 있다. 따라서, 본 논문에서는 현장에서 녹화되고 있는 모든 카메라 소스들을 썸네일 사이즈로 만들어 한눈에 알아볼 수 있는 플랫폼을 구성하여 시청자가 원하는 카메라를 선택해 보고 싶은 장면을 선택할 수 있는 시스템을 제안한다.

글로벌 퍼블릭 클라우드 산업 규모는 매년 폭발적으로 성장하고 있으며 최근 COVID-19 등 비대면 문화 확산에 따라 지속 확장되고 있다. 클라우드 사업자는 유한한 인프라 자원으로 다수의 사용자에게 양질의 IT 서비스 제공을 위해 잉여 자원 할당을 최소화하는 것이 중요하다. 그러나 일반적인 퍼블릭 클라우드 환경에서는 정적 자원 할당 기법을 채택하고 있기 때문에 사용자의 주관적인 판단에 따라 잉여 자원의 발생은 필연적이다. 본 논문에서는 머신 러닝 기법 중 K-Means Clustering 알고리즘을 적용하여 클라우드 동적 자원 관리 기법을 제안한다. K-Means Clustering 기반으로 클라우드에 탑재된 각 Instance 의 자원 사용률 데이터를 분석하고, 분석 결과를 토대로 각 Instance 가 속한 Cluster 에 대하여 자원 최적화 작업을 수행한다. 이를 통해 전체 데이터센터 관점에서 잉여 자원의 발생을 최소화하면서도 SLA 수준 및 서비스 연속성을 보장한다.

최근 물류업계는 코로나 펜데믹 이후 비대면 활동의 증가로 물류의 양이 빠르게 증가하고 있는 추세이다. 이를 해결하기 위해 업계는 인력을 계속해서 투입하고 있지만, 물동량 증가율을 따라잡지 못하고 있다. 본 논문에서는 유전알고리즘으로 결정된 최적 배송 순서 기반으로 작동하는 스마트 자동분류 시스템을 개발함으로써 이 현상을 해결하고자 한다. 해당 시스템은 결정된 배송순서에 맞게 택배를 자동으로 분류할 수 있고, 최종적으로 근무환경 개선과 물류효율성 증대에 기여할 것으로 기대한다.

플립러닝의 핵심 성공요인은 변화된 교수자의 조력자 역할을 통해 학습자가 주도적으로 학습하고 문제를 해결할 수 있도록 유도하는 것이다. 이와 동시에, 공과대학 수업에서는 교수자의 지식전달자 역할과도 균형을 이루어 학습자의 학습내용 이해를 촉진해야 한다. 이에 대한 심층 분석을 위해 교수자 관점의 질적 분석이 진행되고 있는 가운데, 본 연구에서는 학습자의 인식에 기반하여 교수자의 역할을 탐색하였다. A전문대학에서 비대면 환경에서 운영된 공과대학의 플립러닝 기반 수업에서 교수자의 지원 및 역할을 조사한 후 키워드 네트워크 분석을 수행하였다. 연구 결과, '질의응답'과 '설명' 키워드에 대한 분석을 통해 변화하는 조력자로서의 역할이 주효한 동시에 학습내용의 이해도를 향상시키는 전달자로서의 역할도 확인하였으며 이를 바탕으로 제언하였다.

In this study, 1) we compare face channel and non-face channel of life insurance company and non-life insurance company with insurance employs' suitability opinion about channel type, channel property, channel evaluation items requiring when selling insurance products, 2) we construct two social networks for life insurance companies and non-life insurance companies and find/compare two networks' properties, and then want to suggest any direction about sale channel strategy. As the result of comparing social networks of life insurance company and non-life insurance company created by insurance selling channel fit evaluation, employs of life insurance companies have more common opinion than those of non-life insurance companies and so can have more same directional channel strategy. However, property insurance companies need to manage their own channel strategy based on their own circumstance.

After the pandemic, universities are shifting to distance learning, and the information use environment of libraries is rapidly changing. Therefore, there is a need for academic libraries to provide learning and research support services to users in response to these changes. This study analyzed the following contents, focusing on the contents of online services of academic libraries in order to understand the services provided by academic libraries after the pandemic, 1) the current status of online information services provided by 60 academic libraries at domestic and foreign and 2) the experience and requirements for using the online information services of academic library were investigated. As a result of the study, academic libraries at domestic and foreign responded to the untact environment by providing various online information services and users showed high experience and requirements for the electronic resource service and online user education service of academic libraries after the outbreak of the pandemic. Based on the analysis of the current status of online information services provided by domestic and foreign academic libraries after the outbreak of the pandemic, as well as the experiences and requirements of university students, several strategies were proposed to improve the quality of university education and library online information services and to plan services that respond to user needs.

Due to the spread of COVID-19, it is rapidly changing from face-to-face to non-face-to-face work environments and is changing to a digital work environment that can be accessed anytime, anywhere, providing convenience to all lives. However, the number of breaches, personal information leakage, and technology leakage targeting SMEs that are vulnerable to security continues to increase. Accordingly, the government has been continuously promoting the information security consulting support project for SMEs every year since 2014. Therefore, this study intends to develop a performance model and measurement methodology for continuous and more systematic support and efficient management of information protection support projects in consideration of the importance of information security for SMEs. It is intended to be used as basic data when setting future operational directions and goals. The main method of this study is to derive performance models and indicators for SME information security support projects based on domestic literature, case studies, and survey results, utilize expert advice to verify the developed performance measurement indicators, and use pilot-test questionnaires. Conduct evaluation through surveys. Based on the verified indicators, we would like to present a performance model and measurement index for the information security support project for SMEs.

The purpose of this study is as a base study for improving the quality of online classes through multilateral analysis that examines the learning outcoms of educational quality and learning emotions on non-face-to-face online classes at Technical Colleges To this study, from March 1, 2020 to August 31, 2020, a survey was conducted on 1,000 students of H Technical Colleges located in the metropolitan area. The collected data were statistically processed using the SPSS Statistics 18.0 program, t-validation were performed to reveal awareness of online class also correlation analysis and multiple regression analysis were performed to reveal the relation and influence of factors related to quality of instruction, learning emotions, learning outcomes. First, there was a statistically significant difference in perception of online classes by gender and grade. Second, there was a positive correlation between the educational quality, learning emotions, and learning outcomes for online classes. Third, among the learning outcomes, the factors that influence the achievement were the educational content and positive emotions, and the factors that influence the satisfaction among the learning outcomes were the educational content and the learning environment.

The purpose of this study is to identify the level of learning flow, learning satisfaction, academic self-efficacy, academic achievement, and academic stress of nursing students who experienced non-face-to-face online lectures, and to investigate the correlation between variables and the factors affecting academic stress. The data of this study was collected from 143 students at a nursing college in Seoul, through a Google online questionnaire from September 1, 2023 to September 25, 2023, and descriptive statistics, Student's t-test, analysis of variance, Pearson's Correlation, and linear multiple regression were conducted using SPSS Statistics 25.0. Following an analysis of the difference according to general characteristics, academic stress showed significant difference according to Motivation for applying to department(F=4.465, p=.005) and Major satisfaction(F=36.499, p=.000) of the subjects. The result of analyzing the correlation academic stress was negatively correlated with learning flow (r=-.464, p<.010), academic self-efficacy (r=-.522, p<.010), and academic achievement (r=-.379, p<.010), but learning satisfaction was not correlated with academic stress. Variables affecting academic stress were major satisfaction (𝛽=.367, p<.01), learning flow (𝛽=-.186, p<.05), and academic self-efficacy (𝛽=-.241, p<.05), and the explanatory power for academic stress was 40%. The results of this study can be used as basic data for intervention programs for relieving academic stress of nursing students.
