This paper proposes the Alert System, the purpose of which is to detect an accident and to take care of it quickly in a working place. In the previous studies, a wireless network system was suggested using 'Star Topology'. However, this study constructs the wireless network system of Peer-to-Peer Topology, which allows to build more efficient network for communication. Also, with this system it is possible to check other the worker's situation through double sensing with Temperature/Gas sensor and Inclination sensor. In order to take action quickly, the Alert System is using a monitoring program which visualizes a worker's situation and the area where an accident occurs.

We have performed a short-term computer information and communication technology education using Arduino. The purpose of this education was to progress basic training interestingly and discover excellent students. Training was about practicing basic examples about H/W, S/W, communication, and solving creative tasks. We divided training participants into a team composed of each 3 members and educated them for 10 hours. Instructors were consists of 1 main teacher and 3 teacher assistants. Training was about assembling Arduino based robot, blinking LED, operating speaker, serial communication, producing software for wireless communications and autonomous of robot, and control hardware of robot. Through this study, we developed a meaningful ICT integrated curriculum which has high usefulness in a short period. Students participated in this education completed 96% out of 10 creative tasks, and this study analyzes the result of curriculum and suggests further research directions.

In these days, the trends of home networking system is implementation of easily configured system with home security of emergency alarm and visitor verification services. In this paper, we implemented push server system based on Arduino of open source physical computation platform to verify visitors for the homes without home networking services. In the suggested system, visitor verification is performed in and out of home, and home access security of the system could be constructed with low-cost price by use of windows push server system and smart devices with alarm operation in corresponding to not allowed access trying.

본 연구에서는 전신마비 환자들이 안구 마우스를 사용하여 전등, 선풍기, 창문 제어 및 침대 각도 조절을 할 수 있고, 보호자에게 소변통 알림과 응급메시지 알림을 보낼 수 있는 홈 네트워크 시스템을 설계하고 구현한다. 또한 전신마비 환자들뿐만 아니라 일반 사용자들도 이용할 수 있도록 동일한 기능을 모바일 어플리케이션으로 구현한다. 본 연구의 입력장치인 안구 마우스는 삼성전자 창의개발연구소에서 개발한 eyeCan을 사용하였다. 전체적인 시스템은 Arduino를 사용하여 제어하고, 무선 통신은 Xbee모듈을 사용하여 구현하였다. 기존의 홈 네트워크 시스템은 일반 사용자들만 이용할 수 있지만, 본 연구에서는 루게릭 환자처럼 전신을 움직이지 못하는 환자들에게 최적화된 홈 네트워크 시스템을 구축하여 소외계층의 스마트 기기에 대한 접근성을 높이고, 자립심을 키울 수 있도록 도와준다는 점에서 의의가 있다.

In order to interpret rock slope safely and effectively, the mechanical properties of the rock must be carefully investigated. However, due to the limitations of clinometer usage, a new measure of measurement is required to complement these limitations. In this study, a measuring device was developed to analyze the characteristics of joint orientation, and to apply the orientation of joint to the field. The developed measuring equipment is divided into analysis software and hardware. The hardware was composed of a measuring module that measures the joint orientation of rock and a transport module that transmits the measurement data. The software was developed to analyze the orientation of the joint from the data obtained from the measuring module and is named Drone Joint Orientation Survey Measurement. The developed measuring equipment was well field capable if it could not be measured by the inspector, such as in areas where access was difficult, and was capable of effectively analyzing the lab test results for the orientation of the joint.

Mechanical Properties of Rock Slope as a safe and effective interpretation should be thoroughly investigated. Clinometer, however, this new measurement due to the restrictions of the research for the joint orientation is needed. In this study, characteristics of the joint orientation can be used to analyze the joint orientation of developing a joint survey system that can be applied to the field. The system is developed and Analysis software to hardware. Hardware is composed to measure the joint orientation of measuring module, measuring the transfer of data transfer module. From the software is measuring module from the data to analyze the orientation of the joint development, and drone joint orientation survey system named. Can not be measured by the investigation, including regional development approach is a system that has been difficult if the Field Application of the lab test results of the joint orientation and effectively.
