The purpose of this study is to propose the unit plan for home office which can substitute the existing unvaried unit plan in housing and homogeneous working space in office building through the recognition of necessity and possibility about whether home-basedworkandhomeofficecanbeformedornot. Based on the above contents of a research, the following conclusions were summarized; 1. The unit plan of home office was divided into 'jointly-used type' and 'independent-separated type' in accordance with the relationship between housing and working space, 'dwelling-emphasis type' and 'working-emphasis type' in accordance with the grade of ranks between housing and working space. And the universal validity which could accept properly the dweller's characteristics was drawn by the above classification of unit types. 2. The required characteristics in a unit plan for home office were classified into flexibility, privacy, efficiency, identity, amenity. And the analyzing system of planning methodology was assigned according to dividing interior components into space-functional, space-designing interior facts. The planning methodology would have to be considered on the correlation with each required characteristic. As a result of the study, through a planning of independent-separated type, In especial, 'vertical-separated type', it was certificated that vertical-separated type could satisfy a variety of required characteristic in space-designing as well as space-functional aspect.

Corna Virus is being widely spreaded across the world and accelerating working environments to home-based telecommuting environments rapidly. Many companies, however, are afraid of decrease in productivities due to insufficient technology readiness by new technology environments. Therefore, finding out the influencing factors which improve the productivities in home-based telecommuting environments is a very important research issue. This study suggests several influencing factors such as technology readiness, technostress, and control behavior and a research model by literature review. To verify the model a total of 204 questionnaires are collected from office workers who are currently utilizing home-based telecommuting. The statistical analysis show that technostress influences negatively to productivities. In addition, moderating effect analysis show that control behavior affects negatively and technostress positively to alleviate the technostress. The result is expected to provide a theocratical framework for further related research and practical guidelines for improving productivities in home-based telecommuting environments.

This study is approach to the Home-Based Work. More specifically, to examine about the families who try to combined home life and income-generation work under the same roof. Families were looking at Home-Based Work as one solution to the work-family crunch. Many research papers have suggested that Home-Based Work provides an effective way to balance the demands of paid employment and family responsibilities. Therefore, this proposed research reviewed the Home-Based Work as they contributed to individual and family satisfactions. The Prupose of this paper is to address issues related to Home-Based Work from the perspective of theory and application in family resource management, also to suggest a conceptual model for family work activities is advanced. This paper is examined concepts related to Home-Based Work employment that could be used to frame and describe the empirical study are specified. This paper was informed by analyses of data from project NE-167. "At-Home Income Generation: Impact on Management, Productivity, and Stability in Rural/Urban Families". The results from this paper will be helpful in enhancing the stability and satisfaction of families who worked in Home-Based Work.ased Work.

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.

LMS is software that automatically manages educational and learning activities, and is being used in most educational institutions these days when online education is increasing due to the spread of Corona. LMS covers a wide range of methods that are so versatile that they can be used in connection with offline classes as well as online classes. Therefore, it was confirmed that the software is useful not only for educational institutions but also for office workers who want to do online work such as telecommuting during the period of social distancing. This LMS function will be of great help to the development of the education market and online classes in the future.

Since the recent COVID-19 pandemic, Internet usage has increased rapidly and companies have shifted to telecommuting. In addition, as more time at home increases and network traffic through streaming services such as games, the Internet, and Netflix increases, cyberattacks and threats are also increasing. Many countries around the world, including Korea, the US, China, and Japan, have various cloud security policies, but they continue to suffer from various vulnerabilities and cyberattacks. This paper analyzes the current cloud security policies of each country and presents a plan to strengthen the cloud security policies in Korea.

본 연구에서는 실시간적으로 계측, 수집된 자료를 이용하여 도시지역 물순환 전 과정에 대한 개별 물리모델 구동을 실시하고, 수자원의 양적인 흐름을 연계하여 표출하는 도시 수자원 사이버 물리시스템(CPS) 시뮬레이터에 활용되는 입력인자 변동성 분석을 실시하였다. 도시 수자원 실시간 CPS 시뮬레이터의 시나리오 분석을 위한 변동입력인자는 취수량, 타 배수지 구역 공급량, 대상지역 수용가 사용량 변화, 오수전환률 및 오수배출 지연시간 등으로 설정하였으며, 변동입력인자 변화모의를 위한 발현가능한 시나리오를 구축하고, 분석결과를 정량화하여 제시하였다. 본 연구에서 활용된 발현가능한 시나리오는 가뭄 등 취수제한상황에 따른 양적인 공급 흐름모의, 수용가 물 사용 패턴 변화(예, 코로나로 인한 비대면 재택 근무 증가 등)에 의한 상수, 오수변화량 모의 등으로 설정되었다. 분석 결과 다양한 입력인자의 변화에 따른 도시수자원 흐름변화에 영향을 주는 구성요소의 파악과 정성, 정량적 영향을 직관적, 정량적으로 평가할 수 있음을 확인하였다. 도출된 변동성 평가 결과는 설정된 시나리오가 현실화될 경우 효과성 높은 대응책을 마련하는데 활용이 가능하다.

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.

코로나 팬데믹 사태로 인해 업무환경이 재택근무를 하는 환경으로 바뀌고 악성코드의 변종 또한 빠르게 발전하고 있다. 악성코드를 분석하고 백신 프로그램을 만들면 새로운 변종 악성코드가 생기고 변종에 대한 백신프로그램이 만들어 질 때까지 변종된 악성코드는 사용자에게 위협이 된다. 본 연구에서는 머신러닝 알고리즘을 사용하여 악성파일 여부를 예측하는 방법을 제시하였다. 일반적인 악성코드의 구조를 갖는 Portable Executable 구조 파일을 파이썬의 LIEF 라이브러리를 사용하여 Certificate, Imports, Opcode 등 3가지 feature에 대해 정적분석을 하였다. 학습 데이터로는 정상파일 320개와 악성파일 530개를 사용하였다. Certificate는 hasSignature(디지털 서명정보), isValidcertificate(디지털 서명의 유효성), isNotExpired(인증서의 유효성)의 feature set을 사용하고, Imports는 Import Address Table의 function 빈도수를 비교하여 feature set을 구축하였다. Opcode는 tri-gram으로 추출하여 빈도수를 비교하여 feature set을 구축하였다. 테스트 데이터로는 정상파일 360개 악성파일 610개를 사용하였으며 Feature set을 사용하여 random forest, decision tree, bagging, adaboost 등 4가지 머신러닝 알고리즘을 대상으로 성능을 비교하였고, bagging 알고리즘에서 약 0.98의 정확도를 보였다.
