  • Purpose: The government intends to come up with measures to revitalize safety management at construction sites to shift safety management at construction sites from human capabilities to system-oriented management systems using advanced technologies AIoT and Mobile technologies. Method: The construction site safety management monitoring system using AIoT and Mobile technology conducted an experiment on the effectiveness of the construction site by applying three algorithms: virtual fence, fire monitoring, and recognition of not wearing a safety helmet. Result: The number of workers in the experiment was 215 and 7.61 virtual fence intrusion was 3.5% compared to the number of subjects and 0.16 fire detection were 0.07% compared to the subjects, and the average monthly rate of not wearing a safety helmet was 8.79, 4.05% compared to the subjects. Conclusion: It was found that the construction site safety management monitoring system using AIoT and Mobile technology has a valid effect on the construction site.

  • In recent years, connected car, which has sensors and computers attached to vehicles used to detect the surrounding environment, has been actively studied. However, in order to configure the connected car environment, various sensors and roadside equipments are required to detect the surrounding environment of the vehicle, and also communication techniques for transmitting the collected data are in demands. Therefore, in this paper, the mobile virtual fence that collects and communicates the data of the surrounding environment through the sensor mounted on the mobile device is applied to the vehicles that were released before the connected car service environment was constructed, We propose a mechanism to receive the service and show the possibility through experiment.

  • This paper proposes an architecture to develop a mobile package tour application using geofence technology to increase tourism management effectiveness and efficiency. The proposed application allows the tour guide to set a virtual fence on a map with a certain radius dynamically as the virtual boundary to keep tourists inside both when visiting a place or when the tour is moving. The virtual fences are set up for allowing the tour guide to monitoring the tourist's movement by sending a warning to the tourist to get back inside the fence and a notification for the tour guide. If this geofence technology is applied to the package tour application, the tour guide will able to manage the package tour easily and conveniently.

  • In recently, various kinds of services utilizing the location information of the user's smart phone have appeared. Based on this trend, we designed a new type of learning assistant system that utilizes geofencing technology, which is a field of location information technology. This system identifies the location of the classroom using the location information of learner's the smart phone and automatically provides the necessary learning contents to the learner's smart phone when the learner enters the classroom set as the virtual fence area while carrying the smart phone respectively. Our system provides learning contents in a form similar to the form of a message or a mobile coupon and learners are used to such mobile service environments very much. So the use of learning contents provided by our system is expected to help improve the learning effect of learners.

  • The electronic attendance management system is being introduced and operated on a pilot basis by some universities and educational institutions. However, most of the related systems have installed and operated the existing barcode and magnetic card systems. Classroom attendance is managed by introducing RF cards, but it causes problems such as recognition distance (less than 5cm) and the need for a check process in which students have to read the card each time with a reader for attendance. Also, it is not possible to respond in real time to the situation of midterm (early leave, absence from the second lecture time, etc.) because it is used in the lecture time of one subject with the record checked once. In order to solve these problems, the various mobile attendance systems proposed to solve these problems are also unable to fundamentally solve problems such as interim attendance and proxy attendance because they check attendance using only the application of a smartphone. In this paper, we use geofencing technology, which is a positioning-based technology that detects the entry and exit of people, objects, etc. in areas separated by virtual boundaries. The proposed system solves the problem of intermediate attendance and alternate attendance by setting the student to automatically record the access record when entering and leaving the classroom set as a geofence with a smartphone. In addition, it also provides a function to prevent unintentional mistakes that occur through the smartphone by limiting some of the functions of the smartphone such as silence, vibration, and Internet use when entering the classroom.
