In this paper, we propose a control process for a service robot that runs errands for personal belongings using technology elements for Human-Robot Interaction (HRI). Initially, it classifies each space on a grid map mapped based on the indoor environment using Generalized Voronoi Graph (GVG) and registers the location of objects in each classified space, forming a topological map. Subsequently, it utilizes Google’s Speech To Text (STT) to identify voice commands, and integrates this information with the object details on the topological map to automatically generate feasible destinations for the robot based on the estimated location of the object. In an experiment involving instructing the robot with three voice commands for five types of personal belongings located within a simulated household environment, the system achieved a success rate of over 90% in accomplishing errands to the specified locations. This confirms the feasibility of the proposed system for location-based robot services. [ABSTRACT FROM AUTHOR]

This study attempted to develop a beacon scanner based ward monitoring service in order to respond to the new paradigm of medical environment which is trying to introduce ICT technology as medical service to track and manage the spread path of large infectious diseases such as MERS. The study also included beacon hardware development, firmware development for the beacon low-power bluetooth 4.0, and server and web-based dashboard UI development. Using these, we have developed a customized monitoring system that provides functions such as locating patients by location based service and monitoring based on web UI. It is possible to maximize the efficiency of offline hospital services and to value active infection control and patient safety by integrating online technology into the area where online technologies such as beacons are not properly integrated.

This study examined the concept and usage moderated mediating model in structural equation modeling. The theoretical model and hypothesis were developed based on the Location-Based application's Expectancy disconfirmation, Location-Based application's satisfaction, Location-Based application's continuous usage intention, service trust. The statistical results of the two model were compared: one was free model(positive/negative) and the other was the Moderated Mediating Model(positive/negative). A structure equation model analysis was carried out to test the research model. Further studies are necessary to Support the research hypotheses. [ABSTRACT FROM AUTHOR]
