The COVID-19 pandemic has significantly impacted how people work, resulting in a massive shift towards working from home or remotely. Work from home has played a critical role in reducing the transmission of COVID-19 by limiting in-person interactions and reducing the density of people in office buildings. It also enabled businesses and organizations to continue operating while keeping their employees safe and healthy. The COVID-19 pandemic accelerated the adoption of work from home in business and organizational sectors worldwide, and it is likely to continue as a preferred mode of work even after the pandemic is over. This shift towards working from home has not only impacted the way people work but also has significant implications for urban development, transportation, and the environment. This study intends to develop measures for addressing potential physical and mental health issues among remotely working employees. Additionally, it identifies the major influencing factors of home workers' health hazards and proposes improvement measures that can be applied to working from home, along with existing laws and prevention methods.

방송장비가 네트워크 기술을 만나 진화하고 있다. 네트워크 케이블로 초고해상도 영상과 다채널 음향 데이터를 송·수신하고, 다수의 방송장비 제어를 가능케 하는 NDI(Network Device Interface)의 등장으로 방송장비와 네트워크 기술이 융합되고 있다. 최근 국내외 여러 기업이 네트워크 기반의 방송 솔루션을 출시하고 있어, 관련 산업계는 향후 방송장비 시장이 네트워크 기반으로 개편될 것으로 전망하고 있다. NDI는 뉴텍(NewTek)에서 개발한 IP 전송 프로토콜의 일종으로 무(無)손실, 압축, 제로(Zero) 딜레이, 멀티캐스트 등의 특징을 갖고 있다. 기존 비디오 전송 프로토콜이었던 SDI(Serial Device Interface)와는 다르게 네트워크에서 방송장비를 운용할 수 있도록 만들어진 프로토콜이다. 본 논문에서는 NDI를 기반으로 앞으로 다가올 포스트 코로나 시대에 대응할 효율적인 방송 환경을 제안하고자 한다.

2020년 7월 정부는 포스트 코로나 시대를 선언하며, 한국판 뉴딜 정책을 발표하였다. 한국판 뉴딜은 디지털인프라 구축, 비대면 산업육성, SOC 디지털화를 기본방향으로 내세웠으며 빅데이터, 인공지능(AI), 사물인터넷(IoT) 등 4차산업 핵심기술의 육성방안을 제시하였다. 최근 인천공항은 한국판 뉴딜 정부정책에 부응하기 위해 인천공항 K-뉴딜 프로젝트를 추진 중이며, 세부 전략과제로 자산관리의 디지털전환을 위한 IoT기반 스마트 자산관리시스템을 구축 중이다. IoT기반 스마트자산관리시스템은 인천공항에 위치한 실내외 이동형 자산에 대해 끊김없는 위치정보를 제공하는 시스템으로 기존 시스템(RFID) 대비 약 4억 원의 인적, 물적 자원을 절감하는 효과를 나타낼 것으로 예상된다. 본 논문에서는 IoT기반 스마트 자산관리시스템의 핵심기술인 실내외 연속측위 스마트 트래커와 네트워크의 구성, 저전력 위치정보 제공방법을 제시한다.

컴퓨터 전공자들의 프로그래밍 개발 중심의 팀 프로젝트 수업은 프로그래밍 개발 능력과 팀원들 간의 협업 능력을 키울 수 있는 수업으로서, 기존에는 대면수업을 통해 교수자와 학습자간 그리고 팀을 이룬 학습자들 간에 긴밀한 상호작용으로 진행되어왔다. 그러나 2020년 COVID-19의 확산으로 대부분의 대학 수업들이 비대면 방식으로 진행됨에 따라 팀 프로젝트 수업 역시 비 대면으로 운영되어야 했으며 팀 활동을 위해 다양한 온라인 커뮤니케이션 방법이 모색되어야 했다. 본 연구에서는 팀 프로젝트 수업을 기존의 대면 수업으로 운영하였을 경우와 비대면 방식으로 운영하였을 때 학습자들이 느끼는 학습 효과에 대해 비교해보고자 한다. 대면 수업과 비대면 수업에 참여했던 학습자들을 대상으로 설문을 실시하여 팀 프로젝트 수업을 통한 학습 이해도, 수업 흥미도, 학습자간의 소통의 원활성, 수업 참여의 적극성 그리고 전체적인 수업 만족도에 대한 설문 결과를 비교 분석하였다. 향후 포스트 코로나 시대에는 대면과 비대면의 하이브리드 커뮤니케이션 방식이 대세를 이룰 것으로 예측되고 있는 만큼 대학 수업 방식에도 변화가 필요할 것이며 본 연구는 이를 위한 기초 연구로 활용될 수 있다.

Biometric technology is a next-generation information security technology that provides reliability and convenience. As a core technology in the post-corona era, then on-contact biometric access control system is capable of non-face-to-face and automated technology, and is active not only in Korea but also in overseas markets such as the United States, Europe, and the Middle East. There are precautions that must be taken to reflect requirements such as cooperation between companies and approval of the US Food and Drug Admin is tration in developing IoT-based smart device customized sensors and securing H/W systems.

This study explores the impact of technostress on the intention to use telemedicine applications (apps) in the post-COVID19 era, a period marked by the rapid popularization of such apps to mitigate COVID19 infection risks. Utilizing the Technology Acceptance Model (TAM), the study identifies variables and proposes a research model. A questionnaire survey involving 364 adults is analyzed through Partial Least Squares-Structural Equation Modeling. Results indicate positive significance for variables linked to the TAM (perceived usefulness, perceived ease of use, attitude, and intention to use). Notably, techno-complexity negatively affects perceived ease of use, while techno-unreliability negatively impacts perceived usefulness and ease of use. Surprisingly, techno-uncertainty has a positive effect on both perceived usefulness and ease of use. Techno-overload, although negatively impacting perceived usefulness and ease of use, does not reach statistical significance. The study underscores the need to consider both positive and negative aspects, including technostress, when evaluating telemedicine app usage. Additionally, recognizing the varying impact of technostress based on users' ICT(Information and Communication Technology) confidence levels is crucial. Overall, these findings contribute academically to telemedicine app adoption literature and hold industrial significance by providing a user perspective on these apps.

Due to the pandemic caused by Corona 19, cities around the world have faced a change. As the global economic system weakens, localization is increasing in the product production and distribution system. In addition, consumption patterns have changed in urban where localization has been strengthened. As a result, the way physical places are consumed is also changing. Consumption of large multi-use facilities has drastically decreased, the speed of the collapse of the online and offline boundaries has been accelerated, and the consumption of amenities for sharing tastes has become more subdivided, specialized, and private. A big change also appeared in the urban scene, which is perceived as the concentration of urban amenities. Local scale and locality became important in the urban scene, and a new urban scene element called empathy emerged. Empathy aims to connect socially and emotionally to individuals consuming urban amenities. The pursuit of connectivity, taste consumption, and nostalgia. In this study, the space for cultural consumption based on empathy was named as empathetic space and the concept was explained. The importance of empathic space in the urban scene in the future post-corona situation was presented.

This study examines the effect of VMD (Visual merchandising) of unmanned stores and the affordance of unmanned systems on a customer's value and intention of revisit. The proposed research model and developed hypotheses were tested using structural equations modeling based on data collected from 297 customers with experience in unmanned stores. The results of the study confirm the positive effects of the unmanned system's affordance and unmanned stores' VMD on customer value. In addition, there is a positive relationship between a customer's value and intention of revisit. The study provides valuable insights into the sustainability of unmanned stores after post-COVID 19 and the importance of developing unmanned stores' VMD and affordance.

While the United States and other Western states are in trouble with COVID-19 crisis, China is continuing its aggressive ocean expansion with its Gray-zone strategy. The Gray-zone strategy, which China uses around the South China Sea, refers to a strategy that promotes a change in international politics by creating an unclear state, neither war or peace. China, which is trying to expand its influence across East Asia, will also try to project a Gray zone strategy on the Korean Peninsula. The possible scenarios are as follows: 1) South Korea is accidentally involved in a dispute in the South China Sea, 2) Military conflicts between South Korea and China is caused by illegal fishing of Chinese boats in Yellow Sea, 3) China tries to interfere with Socotra Rock, 4) Unlikely, but possible in the future that China induce the military conflicts between Korea and Japan on the Dokdo issue. In order to cope with these scenarios, Korea should prepare the following measures from a long-term perspective: the creation of an Asian maritime safety fleet, the integ rated operation of the navy and the coast guard in the framework of the national fleet, and strengthening the conflict control system for China's provocations.

This study aims at investigating measures to vitalize the Pohang Yeongil New Port and its hinterland in the context of the post Covid-19 pandemic. To identify appropriate strategies, an SWOT analysis combined with fuzzy-AHP(Analytic Hierarchy Process) was applied for strategical priority. Among the SWOT factors, weaknesses and threats were found to be critical. At a more detailed level, the strategic priorities were given to insufficient infrastructure (W), neighboring ports (T), insufficient shipping network (W), low service level (W) and South-North Korea relationships (T). Given these results, several strategies to overcome core weaknesses and threats of the Pohang Yeongil Port were suggested. The results of this study may provide valuable insights for port policy makers.
