Recently, IoT technologies attract much attenction in medical area. Previous medical IoT had focused mainly on chronological diseases or fitness for particular users. Contrarily, medical use of the IoT technologies is now extended for medical institutes and hospitals to care intensively in-house patients, which requires typically more strict and reliable data delivery and security, authentication and authorization. This study defines scenario of the medical IoT for the intensive care and proposes an architecture of the medical IoT services. We implement a testbed using commerical sensors and Arduino board together with a Web-based platform. Experiment results on the testbed show that our approach can be feasible for the medical system in terms of latency and accuracy in medical data delivery.

One of the important factors among the smart farm factors is environmental measurement. This study tried to design an environmental measurement monitoring system through Bluetooth wireless communication with LoRa using the open source programs Arduino, App Inventor, and Node Red. This system consists of Arduino, LoRa shield, temperature and humidity sensor (SHT10), and carbon dioxide sensor (K30). The environmental measurement system is configured as a system that allows the sensor to collect environmental data and transmit it to the user through wireless communication to conveniently monitor the farm environment. As libraries used in the Arduino program, LoRa.h, Sensirion.h, LiquidCrystal_I2C.h and K30_I2C.h were used. When receiving environmental data from the sensor at regular intervals, coding using average value was used for data stabilization. An Android-based app was developed using Node Red and App Inventor program as the user interface. It can be seen that the environmental data for the sensor is well collected with the screen output to the serial screen of Arduino, the screen of the smartphone, and the user interface of Node Red. Through these open source-based platforms and programs will be applied to various agricultural applications.

최근 들어 일반인들도 다중 콥터와 4k 고성능 카메라를 장착한 상용 드론을 구매하여 자신의 취미 활동용으로 사용하고 있다. 드론을 이용한 많은 동호회가 생겨나고 1인 1드론, 개인용 드론의 시대가 시작되고 있다. 또한 사물인터넷의 시대에 걸맞게 아두이노, 라즈베리파이와 같은 오픈하드웨어 플랫폼과 오픈 소스를 이용하고 저가형 3D printer 의 보급으로 자신만의 독특한 형태를 지니는 기체 제작을 시작하고 있다. 이에 본 논문에서는 3D 캐드를 이용한 위상최적화 기법을 적용하여 기존 상용 기체의 강성은 그대로 유지하되 기체 프레임 무게를 절반으로 줄인다. 또한, 풍동실험을 진행해서 기존 기체에서 발생하는 유체흐름을 분석하고 새로운 기체를 적용했을 경우에도 유사한 유체흐름이 나타나도록 설계하여 3D 프린터를 사용하여 제작하였다.

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.

Due to the increase in single-person households among the people who have companion animals, it is difficult to feed them to companion animals in the absence of the owner, so an automatic feeding machine was designed. In this paper, we propose an automatic feeding machine that has a drug distribution function as well as feeds using the Arduino platform. It is expected that in the proposed automatic feeding machine, users can access the food service through the website, and experience the convenient and extended food service function through the automatic dispensing system that combines the two materials.

The smart city is developing an energy system efficiently through a common management of the city resource for the growth and a low carbon social. However, the smart city doesn't counter a verification effectively about a anomaly pattern detection when existing security technology (authentication, integrity, confidentiality) is used by fixed security key and key deodorization according to generated big data. This paper is proposed the "security nonce generation based on security nonce generation" for anomaly pattern detection of the adversary and a safety of the key is high through the key generation of the KDC (Key Distribution Center; KDC) for improvement. The proposed scheme distributes the generated security nonce and authentication keys to each facilities system by the KDC. This proposed scheme can be enhanced to the security by doing the external pattern detection and changed new security key through distributed security nonce with keys. Therefore, this paper can do improving the security and a responsibility of the smart city platform management data through the anomaly pattern detection and the safety of the keys.
