Network-based intelligent robot is connected with network system, provides interactions with humans, and carries out its own roles on ubiquitous computing environments. URC (Ubiquitous Robot Companion) robot has been proposed to develop network-based robot by applying distributed computing techniques. On URC robot, it is possible to save the computing power of robot client by environments, has been proposed to develop robot software using service-oriented architecture on server-client computing environments. The SOMAR client robot consists of two layers - device service layer and robot service layer. The device service controls physical devices, and the robot service abstracts robot's services, which are newly defined and generated by combining many device services. RSEL (Robot Service Executing Language) is defined in this paper to represent relations and connections between device services and robot services. A RESL document, including robot services by combining several device services, is translated to a programming language for robot client system using RSEL translator, then the translated source program is compiled and uploaded to robot client system with RPC (Remote Procedure Call) command. A SOMAR client system is easy to be applied to embedded systems of host/target architecture. Moreover it is possible to produce a light-weight URC client robot by reducing workload of RSEL processing engine.

기술의 발전으로 인해 스마트 가전제품이 늘어나며 스마트 홈 기술이 주목을 받고 있다. 그러나 이러한 기술은 설정과정의 복잡성으로 사용자들이 쉽게 접근하기 어렵다. 특히 디지털 기기 사용에 익숙하지 않은 사용자들을 스마트 홈 기술로부터 소외시키는 결과를 낳고 있다. 본 논문에서는 사용자 친화적인 스마트 홈 시스템을 제안한다. 사용자의 시선 방향을 추적하여 디바이스를 선택하고 간단한 인터페이스의 컨트롤러로 디바이스를 손쉽게 조작할 수 있도록 한다. 또한, 생성형 인공지능과 RAG 를 결합하여 사용자가 가전제품과 자연스럽게 대화하며 정보를 얻을 수 있는 인터페이스를 제공한다.

As the use of various IoT devices increases, the importance of IoT platforms is also rising. Recently, artificial intelligence technology is being combined with IoT devices, and research applying a neuromorphic architecture to IoT devices with low power is also increasing. In this paper, an application scenario is proposed based on NA-IDE (Neuromorphic Architecture-based autonomous IoT application integrated development environment) with IoT devices and FPGA devices in a GUI format. The proposed scenario connects a camera module to an IoT device, collects MNIST dataset images online, recognizes the collected images through a neuromorphic board, and displays the recognition results through a device module connected to other IoT devices. If the neuromorphic architecture is applied to many IoT devices and used for various application services, the autonomous IoT application integrated development environment based on the neuromorphic architecture is expected to emerge as a core technology leading the 4th industrial revolution.

Recently, smart wearable products, including electromyography (EMG) measurement devices and clothing, have been developed to monitor users' exercise levels, muscle activation, and muscle balance more effectively during fitness activities. However, technical and socioeconomic barriers, such as flexibility and durability, still pose challenges in terms of comfort, ease of wear, and wearability of smart clothing, which includes devices and circuits. To address these issues, this study developed a wearable EMG device integrated with clothing to collect valid EMG signals from desired muscles while maintaining comfort, functionality, and ease of wear. After deriving a combined structure that could stably position the wearable device within the clothing, a prototype was manufactured and evaluated for fit, compression, comfort, and exercise comfort test by ten participants (height = 176.2 cm, weight = 76.4 kg, chest circumference = 101.2 cm). The study found that the prototype had smaller circumferences around the chest, waist, and abdomen compared to commercial products, resulting in lower ratings for wearing comfort and ease of wear. However, the prototype received high ratings for fitting, pressure, and the exercise comfort test. Valid signals were obtained when the EMG device was combined to the prototype for the rectus femoris muscle, indicating stable positioning of the device during exercise.

무선 BAN은 인체를 중심으로 3m 이내에서 이루어지는 통신을 위한 기술이다. 무선 BAN은 인체 내 외부에서 의료용 서비스를 위하여 여러 개의 채널로 구성된 MICS(Medical Implanted Communication Service) 주파수 대역을 사용한다. MICS는 다중 채널 환경에서 LBT(Listen Before Talk)와 AFA(Adaptive Frequency Agile)을 사용하여 장치간의 간섭을 최소화한다. 경쟁기반의 LBT와 AFA는 데이터 전송의 안정성을 보장하지 못할 뿐만 아니라 채널 홉핑(Hopping)으로 인한 전력 소비를 야기한다. 본 논문에서는 의료용 데이터의 주기적인 특성과 전송 안정성을 고려하여 예약 기법의 채널 액세스 관리 기법을 제안한다. 여러 채널 가운데 하나의 채널을 제어 채널로 설정하고 나머지는 데이터 전송을 위한 채널로 설정한다. 코디네이터는 제어 채널에서 beacon을 전송하여 디바이스에게 데이터 채널을 할당한다. 예약방식을 통하여 채널 할당의 안정성을 확보할 뿐만 아니라 디바이스의 요구 사항에 따라 채널을 유동적으로 결합함으로써 채널의 효율성을 개선한다. 또한 제어 채널 관리 방안을 통하여 LBT 장치와 상호 운용성을 확보하고, 시뮬레이션을 통하여 예약방식의 채널 관리 방안의 효율성을 검증한다.

In this paper, we propose a system that improves the data integrity of IoT(Internet of Things) devices in the virtual environment by combining Hyperledger Indy and MQTT(Message Queuing Telemetry Transport). The system complements the limitations of the centralized system by realizing a DPKI(Decentralized Public Key Infrastructure) structure that utilizes a distributed network in publish-subscribe(pub/sub) pattern communication. Digital signature technology was applied to ensure the data integrity of IoT devices and communication scenarios between the four core components of the client, IoT device, broker, and blockchain, as well as a topic structure using a decentralized identifier to ensure safety in the virtual environment. We present a systematic method for transparent data exchange. To prove the performance of the proposed system, this paper conducted experiments on four scenarios and evaluated communication performance in a virtual environment. The experimental results confirmed that the proposed system provides a reliable IoT data communication structure in a virtual environment.
