Carpal tunnel syndrome, carpal tunnel becomes part of a narrower median nerve pain occurs pressed. How a stable wrist stretch for the prevention of carpal tunnel syndrome is required, it should life guides to fit the user is provided. In this research, users themselves recognize the risk of carpal tunnel syndrome, to be able to stretch, it implements the application. Application, based on the usage time set by the user, executes the alarm and lock. At this time, the user may utilize arduino and inertia sensor, it is possible to wrist stretch, to analyze usage patterns, it is possible to provide a medical information and life guides to suit the user. Data using Bluetooth 4.0 communication has been to meet the runaway. In order to evaluate the mounted system, targeting four subjects, the time and the touch frequency of usage of the 3-day smartphone measured, as a result of the questionnaire, it reduces the frequency of use of smartphones, a positive it was possible to prove the effect.

With the development of modern technology, the use of unmanned automation equipment that can replace humans in logistics and industrial sites is increasing. The technology of one such automation facility, the Unmanned Carrier (AGV), includes Line Tracing, which allows you to recognize a line through infrared sensors and drive a predetermined route. In this paper, the shortest time algorithm using Arduino is configured in the line tracing technology to enable efficient driving. It is also designed to collect location and time information using RFID tags.

Physical experiment through MBL has been used in many schools for a long time since students can check the experiment results immediately and conduct the experiment easily. However, conducting the experiment, not knowing the principle of the device or simply concentrating on the derived data has been raised as the problem of MBL experiment. To supplement this problem, this study measured the acceleration of gravity with the picket fence method, which is often used in MBL experiment, utilizing Arduino, calculated the error rate through a comparison to the actual acceleration of gravity and discussed the educational application of the experiment to measure it. As a result of the experiment, the error rate between the acceleration of gravity calculated by the experiment and the actual acceleration of gravity was about 1%, so it turned out that relatively accurate measurements were possible. Also, the sample mean of the experimental value was included in the confidence interval of 95%, so it could be concluded that it was a significant experiment. In addition, this study showed the possibility of the educational application of the experiment to measure it through the following: It can supplement the structural disadvantages of MBL; it can consider the interaction between Physics and Math; it is possible to converge with information course in STEAM education; and it is inexpensive to be equipped with the equipment. Hopefully, the physical experiment utilizing Arduino will further be revitalized in science gifted education based on this study.

Utilizing the Arduino platform to express the emotions that reflect the colors expressed the jewelry. Emotional color expression utilizes Plutchik's Wheel of Emotions model was applied to the similarity of emotions and colors. It receives the recognized value from the temperature, lighting, sound, pulse sensor and gyro sensor of a smart jewelery that can be easily accessible from your smartphone processes that recognize and process the emotion applied the rules of inference based on ontology. The emotional feelings color depending on the color looking for the emotion seen in context and applied to the smart LED jewelry. The emotion and the color combination of contextual information extracted from the recognition sensors are reflected in the built-in smart LED Jewelry depending on the emotions of the wearer. Take a light plus the emotion in a smart jewelery can represent the emotions of the situation, the doctor will be able to be a tool of representation.

In this paper, a drunk driving prevention system was implemented to measure drunk driving before starting to prevent drunk driving accidents caused by complacency after drinking. In order to prevent a situation in which a driver but not a driver authenticates instead of a driver, the identification means was strengthened and the alcohol sensor was implemented to operate when the wind sensor measured above the set value set. Through this system, the driver's alcohol measurement process was strengthened. Sensors were determined through various experiments, and finally, when the alcohol concentration was 0.03% or more, the DC motor was stopped and the vehicle was designed to be unable to operate, thereby implementing a system in which drunk driving was prevented in advance.

SW 교육에 있어서 입문자의 흥미를 유발하고자 블록 기반인 스크래치와 엔트리가 도입되었고 많은 교육 기관에서는 이후 ARDUINO, C, JAVA, PYTHON 등을 선택 교육하고 있다. 이 과정에서 코딩보다는 사고력을 강조하며 정보 교과 내에서 문법 공부하는 것을 기피하는 풍토를 보인다. 이러한 점은 2015 개정 교육과정 지침에서 특정 언어의 기능습득에 치우치지 않고 학습자의 수준에 맞추어 적절한 도구를 선택하도록 하여 사실상 교수자의 재량에 두고 있는 점에서도 파악할 수 있다. 코딩의 문법학습을 피하는 경향은 코딩교육 도입 초기의 취지와는 다르게 공교육 내에서의 코딩교육의 활성화에 부정적 요소로 작용할 여지가 크다고 우려된다. 따라서 현재 출판된 정보 교과서에서 다루는 프로그래밍 언어의 종류를 조사하고 코딩 문법학습을 최소화를 할 수 있으며 블록코딩에서 텍스트 코딩으로 전환 시 학습자의 부담을 감소할 수단으로 PROCESSING를 통한 과정을 제안하는 바이다.

In the 21st century, computers are useful tools for our lives. However, such computers are difficult to use because they are inputted with a mouse and keyboard. The goal of this paper is to design and implement a 'foot keyboard' that can be typed using pedals and using the "cheonjiin" input method with minimal foot movement so that even people with impaired hands can use the computer comfortably.

4차 산업혁명의 핵심으로 떠오르고 있는 드론 산업의 성장속도가 점차 빨라짐에 따라 드론 활용도가 점차 높아지고 있다. 물류시장의 화두는 신속한 배송이지만 기존 택배 및 우편물 등을 배송하기에는 도로의 교통상황에 따라 시간이 많이 들고 인력비와 수송비등 자원이 많이 필요하다. 본 논문은 기존의 택배 시스템에서 사람이 직접 이동해서 물건을 전달하는 방식이 아니라 드론을 이용하여 효과적으로 배송할 수 있는 방법을 제안하고자 한다. 드론을 원하는 목적지까지 보내는 과정에서 발생하는 여러 돌발 상황을 대처할 수 있도록 GPS 및 아두이노기반의 여러 센서들을 이용하여 안정적으로 제어하는 것이 본 논문의 목적이다. 그 외 문자알림 서비스를 이용하여 택배의 실시간 위치를 알 수 있게 하고 도착알림 등을 받게 하여 편리성을 높이는데 역점을 두었다.
