Previous research on work and life balance mainly focused on workers' passive acceptance of interferences rather than active management of them. However, workers can also actively manage boundaries to enhance work and life balance. To find ways to enhance work and life balance, especially in the context of Smart Work, factors having effects on the work/nonwork interferences and their relationships should be firstly investigated. The results show that in a work domain, both boundary strength at work and job autonomy negatively influence on the nonwork to work interferences; in a nonwork domain, both boundary strength at nonwork and autonomy have negative effects on the work to nonwork interferences.

현재 규모가 작은 이름바 '동네 병원'에서는 환자관리의 어려움과 동네 병원의 특성상 병원 자체적인 예약 서비스를 실시하지 않는 병원이 많다. 또한 환자는 기다리는 환자들이 많은 시간에 방문하는 경우, 병원 안에서 자신의 순번을 마냥 기다리는 경우가 빈번하게 발생한다. 이와 같은 불편들 때문에 간호사는 고객에게 간호업무 이외에도 정신적인 서비스를 제공해야 하며, 환자들은 자신의 순번이 오기만을 하염없이 기다리는 등의 불필요한 시간 소모가 크고 자신의 앞에 대기하고있는 환자가 많으면 병원이 어수선하고 앉을 자리조차 없이 서서 기다리는 경우도 허다하다. 이런 불편함들을 조금이나마 해결해주고자 본 논문에서는 저전력 블루투스 (BLE) 기술 기반의 비콘(Beacon)을 활용하여 스마트폰을 이용해 병원 내부적인 예약 서비스가 없어도 자체적인 예약 서비스와 이용자가 스마트폰을 가지고 병원에 들어가기만 해도 자동으로 병원 진료접수를 진행하고 이를 효과적으로 관리할 수 있는 사물인터넷 기반 병원 대기시간 최적화 서비스와 그 핵심 알고리즘을 제안한다. 이를 이용하면 간호사는 이전보다 간호업무에 더 집중할 수 있게 되고, 환자는 북적거리는 병원 대기실에 앉아서 기다리지 않고 실외로 나가 자신의 업무를 보고 진료시간에 맞춰서 돌아와 진료를 받는 '사람이 많아도 한적해 보이는 스마트 병원'을 만들 수 있을 것이라 본다.

In the case of SAE autonomous driving levels 2 and 3, since complete autonomous driving is impossible, the take-over process is essential, and take-over time(TOT) is the most important factor in determining the safety of the autonomous driving system. Accordingly, research on TOT is being actively conducted, but each research is independently conducted and general conclusions that integrate various research results are required. Therefore, in this study, the factors affecting TOT were analyzed using meta-analysis, which integrates the results of individual studies and presents an integrated opinion. As a result of meta-analysis, a total of 10 influencing factors were selected, and most of them were related to the non-driving related task(NDRT) type. In addition, implications for the future research direction of take-over and NDRT were presented.

Recent increasement of metropolitan infrastructure due to rapid expansion and development of urban areas which caused complexity and diversification of management system demands higher cost and effort to manage and maintain the facilities. The reason why it requires continuous and systematic management by national government is that the infrastructure facilities takes important role as it is directly related to public's living. Thus this study suggests an efficient management plan for increasement of work efficiency, cost reduction, and time saving by introducing 3D geospatial information system for water distribution reservoirs which is managed by the Office of Waterworks Seoul Metropolitan Government. This study evaluates and quantifies the range of work improvement using the 3D GIS technology through carrying out a survey targeting people in charge of the Office of Waterworks Seoul Metropolitan Government and other 8 offices. From the result of the research, applying the 3D-GIS improves by 90.32%, 93.55%, and 91.61% in the area of work efficiency, cost reduction, and time saving respectively. Consequently, using 3D GIS in future management of infrastructure could be used as a way of producing base data which supports administrative decision making through statistical and case analysis based on continuous data management. Also it would contribute to improving work efficiency by improving management system through preventing data omission.

Quality management work at construction sites demands substantial time and effort, involving the preparation of documents in Excel, approval processes, and the execution of quality tests. These Excel-based tasks include printing quality test reports, performing quality tests, generating and approving test reports, and preparing management ledgers. This division of processes extends the duration of work and diminishes efficiency. Accordingly, a cloud-based construction site quality management system was developed to enhance the productivity of quality management work. The purpose of this study is to analyze the productivity of the construction site quality management system, which is in the early stages of implementation at construction sites. This study implemented the construction site quality management system at a road construction site and scrutinized subsequent alterations in the quality management workflow before and after the implementation. Additionally, a survey was conducted among quality control engineers to collect data on work time both before and after the introduction of the construction site quality management system. Based on the collected data, the Monte-Carlo simulation method was applied to analyze the productivity improvement effect of the construction site quality management system, and the results were presented. The results of this study can serve as foundational data for future research endeavors focused on the automation of quality management works.

Target businesses mean a business of specific and detailed management targets being used for realization of applications for business. Though elicitation methods of target businesses exist variously, it mostly requires much experience and consumes much time. So because its procedure is not suggested clearly, there is much difficulty when a beginner elicits target businesses. Accordingly, this study proposes a method capable of eliciting target businesses procedurally from given business statements. And hypothetical business statements were used as a case, and a method proposed from this study was applied to given business statements with the target of undergraduates, graduate students and company employees. And as a result of questioning an individual performance method and analyzing its reliability, a reliable result was obtained generally. Due to this, it could be confirmed that the method suggested in this study is not only used in the field, but also can be used easily even for a beginner.

Natural disasters are occurring frequently due to typhoon and flood. Especially, damage scales are increasing these days because of climate change. When natural disasters occur, civil engineering officers investigate them for the recovery. If public facilities are damaged, the disaster damage investigation must be finished within 7days. Currently, natural disaster damage investigation is done on two levels, field investigation and data input into NDMS. However, having those two overlapped most of the time, and we must do subsidiary works things to register field investigation data into system. Work efficiency is decreased due to repetition of additional work. So, many civil engineering officers indicated problems such as lack of manpower and time. In this study, We developed work process on natural disaster damage investigation that involves using smart phone to solve problems such as shortage of time and manpower.

This study is a secondary data analysis to investigate the nursing tasks performance, appropriate performer, and job satisfaction in the general wards with sift work. We found that nurses performed direct (45%) and indirect nursing (55%). The workload per shift was 37.2% in the day, 35.6% in the evening, and 27.2% at night. The tasks performed after handover were 'direct nursing (34.5%)' and 'documentation and notification (25.8%)'. Nurses responded that there were some tasks that could be delegated to nursing assistants or had ambiguous boundaries with other medical personnel. There was a significant correlation between compliance to the job description of the night shift and job satisfaction (rs=.43, p=.01). These results imply that it is necessary to establish strategies that will enhance work efficiency based on job analysis by shift work, reduce handover time using EMR system, stmart devices, and clarify appropriate performers.

This study was attempted to predict the direction for ward nursing work through robotic systemization. Robot systems have not been universalized due to difficulties in operation, space constraints, and high prices. The robotic systemization should be focused on the robotic systemization of simple and repetitive tasks. The idea of a robot system for measuring vital signs and a robot system that helps bed sheet exchange is worth discussing with the engineering field. In addition, for successful nursing and interdisciplinary convergence, a detailed analysis of nursing work is required, and in order to overcome the trial and error of convergence, it is necessary to establish a converging society between nursing and interdisciplinary systems. Robotic systemization of successful ward nursing work will not only generate profits for hospitals, but also raise the status of nurses and will be the starting point for innovation in nursing work.
