Software education will be implemented in elementary, middle and high schools from the 2018 school year. One of the core contents of software education is algorithm education. As with other subjects, algorithmic education can also be seen as the success of students' initiative. And students' initiative learning can lead to increasing students' interest and commitment. In this paper, I propose the concept of software battle by applying sports games to algorithm education. The software battle defined that the programmed objects play to solve a given problem without human intervention in the virtual world. This can be applied to various topics. In this paper, I tried to apply it to sorting numbers which is a representative subject of algorithm education. The results of applying the algorithm education to the software battles showed a positive response, although the students felt the unfamiliar side. This indicates that the software battle can be used as one of the various education methods.

In this paper, we propose a system that can identify the position of naval ship personnel at a glance by utilizing the Bluetooth-based beacons. The system proposed in this paper, installs a beacon receiver which are short-range wireless communication devices for each cabin, and in the installed beacon receiver receives information from beacons held by personnel. The received information is transmitted to the processing server, and the processing server transmits the integrated information of the cabin to the display module. Display module displays personnel information located in each cabin. As a result of simulations using the designed system, it was confirmed that the integrated information is transferred to the display module and displayed. Unlike existing situations where personnel positions are reported orally within the ship, the system can quickly and in real time determine the position of personnel, allowing for the management of personnel in non-combat situations and the rapid battle disposition in combat situations. This is expected to contribute greatly to the improvement of fighting power.
