Recently, research on digital twins to generate digital information and manage construction in real-time using advanced technology is being conducted actively. However, in the construction industry, it is difficult to optimize and apply digital technology in real-time due to the nature of the construction industry in which information is constantly fluctuating. In addition, inaccurate information on the topography of construction projects is a major challenge for earthmoving processes. In order to ultimately improve the cost-effectiveness of construction projects, both construction quality and productivity should be addressed through efficient construction information management in large-scale earthworks projects. Therefore, in this study, a 3D digital map-based AR site management work support system for higher efficiency and accuracy of site management was proposed by using unmanned aerial vehicles (UAV) in wide earthworks construction sites to generate point cloud data, building a 3D digital map through acquisition and analysis of on-site sensor-based information, and performing the visualization with AR at the site By utilizing the 3D digital map-based AR site management work support system proposed in this study, information is able to be provided quickly to field managers to enable an intuitive understanding of field conditions and immediate work processing, thereby reducing field management sluggishness and limitations of traditional information exchange systems. It is expected to contribute to the improvement of productivity by overcoming factors that decrease productivity in the construction industry and the improvement of work efficiency at construction sites.

A smart grid is a next-generation power grid that can improve energy efficiency by applying information and communication technology to the general power grid. The smart grid makes it possible to exchange information about electricity production and consumption between electricity providers and consumers in real-time. Advanced metering infrastructure (AMI) is the core technology of the smart grid. The AMI provides two-way communication by installing a modem in an existing digital meter and typically include smart meters, data collection units, and meter data management systems. Because the AMI requires data collection units to control multiple smart meters, it is essential to ensure network availability under heavy network loads. If the load on the work done by the data collection unit is high, it is necessary to allocation new data collection units to ensure availability and improve energy efficiency. In this paper, we discuss the allocation scheme of data collection units for the energy efficiency of the AMI.

Purposes: This study was to validate the Robotic Smart Work System that can provides better working conditions and high productivity in unstructured environments like bio-industry, based on a tele-operation system for fruit harvesting with low cost 3-D positioning system on the laboratory level. Methods: For the Robotic Smart Work System for fruit harvesting and cultivation management in agriculture, a vision based tele-operating system and 3-D position information are key elements. This study proposed Robotic Smart Farming, an agricultural version of Robotic Smart Work System, and validated a 3-D position information system with a low cost omni camera and a laser marker system in the lab environment in order to get a vision based tele-operating system and 3-D position information. Results: The tasks like harvesting of the fixed target and cultivation management were accomplished even if there was a short time delay (30 ms ~ 100 ms). Although automatic conveyor works requiring accurate timing and positioning yield high productivity, the tele-operation with user's intuition will be more efficient in unstructured environments which require target selection and judgment. Conclusions: This system increased work efficiency and stability by considering ancillary intelligence as well as user's experience and knowhow. In addition, senior and female workers will operate the system easily because it can reduce labor and minimized user fatigue.

최근 코로나 19의 세계적 대유행 이후로 비즈니스 업무환경이 스마트워크로 급격하게 변하고 있다. 스마트워크는 기본적으로 언제 어디서나 일을 할 수 있는 시스템을 근간으로 하고 있다. 스마트워크가 성공하기 위해서는 이러한 시스템의 구축과 운영 문제가 중요할 뿐만 아니라, 스마트워크 도입이 미치는 조직문화에의 영향을 연구하는 것도 중요하다. 본 연구에서는 한국의 레저 서비스 대기업인 H사에서 경영상 강조하고 있는 조직 문화의 일곱 가지 차원 - 전략적 혁신성, 조직 유연성, 공정한 인사관리, 합리적 의사결정, 조직 활력, 신뢰 협력, 리더십 - 에 있어서 스마트워크 전후로 어떤 변화가 있는지 설문과 인터뷰를 통하여 조사하였다. 조사결과 전략적 혁신성, 조직 유연성, 조직 활력, 신뢰 협력의 네 가지 차원에서는 직원들의 평가가 통계적으로 낮아진 것으로 나타났고, 공정한 인사관리, 합리적 의사결정, 리더십의 측면에서는 큰 변화가 없는 것으로 나타났다. 도입초기 단기적 현상일수도 있어 앞으로의 변화도 관찰할 필요가 있지만, 기업 관점에서 궁극적으로 유연한 업무 환경의 변화를 추구하는데 있어서 직원들로 하여금 전략적 혁신성, 조직 유연성, 조직 활력, 신뢰 협력과 같이 경영상 중요한 조직 문화의 측면에서 적극적으로 준비하고 대응하는 것이 필요함을 시사한다. 조직 활력이 상대적으로 낮아지고, 조직구성원간 신뢰 소통과 협력은 감소하는 것은 굉장히 부정적 변화로서 적극적 관리가 필요하다. 이어진 인터뷰에서는 스마트워크 도입의 성공적 정착을 위해서는 리더십의 역할이 중요하게 나타나고 있어, 향후 일하는 방식의 변화에 따라 경영진 리더십의 역할이 더욱 강조될 것이라는 것을 시사하였다.

This research note probes the largely ignored sphere of smart tourism curriculum as destinations and institutions seek to develop graduates ready to embrace the demands and challenges of future work environments where technology has a ubiquitous presence. This knowledge gap is somewhat surprising, even as destinations progress towards smart tourism futures, without necessarily clarifying what human resources need to possess in the coming decades. Drawing from available smart tourism curriculum across the globe, and emergent trends associated with Generation Alpha and Beta, this research note paints a timely picture of how smart tourism curriculum should be designed and developed to meet the needs of industry and consumer demands and expectations.
