In this paper, we have developed the balance board with electronic devices to use in various fields of remedial and physical balance exercise with interesting game and the functional game. Rehabilitation training using a funny game will be effective for patient's rehabilitation training. A Personal training system uses a balance board with an acceleration sensor and the game controlled by physical balance. To evaluate the operation of the developed system, we developed rehabilitation training game. The proposed game can be applicable to rehabilitation and balance training, and suggested game interface method could use a commercial game with various function through our emulator.

In this paper, we present FinDID (Financial Decentralized IDentity), a blockchain-based DID(Decentralized IDentity) service that can flexibly control personal information or credentials through a systematic verification method while complying with the standard service scheme of decentralized identity for the financial sector. DID is an identity management system used in a decentralized environment without a specific certification authority, and as a technology that allows users to control their own information, it can realize self-sovereignty over users' own personal information. Through FinDID, users receive credentials that authenticate their various personal information from the issuer, select only the claims required by the target financial service using their personal electronic wallet, create presentations from credentials. Then they submit it to the financial service, leading to their qualification from the service. FinDID consists of electronic wallet, credential issuer, credential storage, DID service including DID management contract and credential management contract, and financial services using this service scheme. The DID service manages each user's DID and supports all verification processes of the associated identity management scheme.

As the delivery industry grew around the restaurant industry along with the COVID-19 situation, the number of delivery workers increased significantly. Along with that, new forms of delivery using personal mobility (PM) also emerged and two-wheeled or PM-related accidents are steadily increasing. This study manufactures a PM's driving analysis device to establish a safe delivery monitoring environment. This system was constructed to process data collected from the driving analysis device and through a cloud server, which would recognize and record special situations (acceleration/deceleration, speed bump) that could occur during the PM's driving situation. As a result, the angular speed, acceleration, and geomagnetic values collected from the IMU in the device were able to determine whether to drive, drive on the sidewalk, and drive on the speed bump. This technology was able to achieve approximately 1600 times more driving information storage efficiency than conventional image-based recording devices.

In this paper, a user-friendly mobile photo album system and albuming functions to support it are introduced. Stand-alone implementation in a mobile device is considered. The main idea of user-friendly photo browsing for albuming functions is to enable users to organize and browse their photos along semantically meaningful axes of events, personal identities, and categories. Experimental results demonstrate that the proposed method would be sufficiently useful and efficient for browsing personal photos in mobile environment.

UPIMS(University Personal Information Management System) 서비스는 컴퓨터를 이용하여 대학생들의 일정 관리를 위한 서비스 였으나, 인터넷과 무선 통신이 발달하면서, 사용자들이 개개인의 정보를 전화 단말기와 Office용 PC, 가정용 PC에서도 정보를 공유하고자 하는 요구가 발생하였고, 각 정보를 팀원간 공유를 통해 사용자 자신이 언제, 어디서나 원하는 정보를 전달받기를 원하며, 전달해주기를 원하고 있다. 이에 무선 인터넷 서비스를 통해 다양한 무선 단말기에 구애받지 않고, 사용자 정보를 관리할 수 있는 서비스를 가능하게 하기 위하여, 무선통신 기반의 PIMS(Personal Information Management System) 서버를 구축하여 개개인의 일정관리, 주소록 관리, 그룹 관리 학사일정 등의 다양한 개개인의 정보 맞춤 서비스를 수행하는 기능을 제공한다. 뿐만 아니라, UPIMS서버는 인터넷상의 다양한 정보를 관리 및 저장하여 가입자의 요구시 사용자 단말기에 적합한 형태로 정보를 변환하여 전송하는 역할을 하며 예약 시스템에도 활용 가능하게 된다.

In recent years, machine learning algorithms are continuously being used and expanded in various fields, such as facial recognition, signal processing, personal authentication, and stock prediction. In particular, various algorithms, such as deep learning, reinforcement learning, and Q-learning, are continuously being improved. Among these algorithms, the expansion of deep learning is rapidly changing. Nevertheless, machine learning algorithms have not yet been applied in several fields, such as personal authentication technology. This technology is an essential tool in the digital information era, walking recognition technology as promising biometrics, and technology for solving state-space problems. Therefore, algorithm technologies of deep learning, reinforcement learning, and Q-learning, which are typical machine learning algorithms in various fields, such as agricultural technology, personal authentication, wireless network, game, biometric recognition, and image recognition, are being improved and expanded in this paper.

In this paper, we propose a real-time ECG monitoring system for personal health records. This study aims to provide services that help patients to monitor their own physical condition and manage their own health records consistently, whereas existing medical services are Medical Institute-Centric model. The system is composed of web server, smart phone, and ECG meter, and web page. Without time and space restraints, It provides us with managing personal health records by performing patient's ECG measurement and real-time monitoring. And also Real-time bidirectional communication between smart phone and web page can be performed rapidly by applying the ECG monitoring with WebSocket Technology that follows HTML5 standard. Through this system, It can handle patient in need immediately.

본 논문에서는 잊혀질 권리에 대한 법제도 및 법정책적 검토를 논하고자 한다. 잊혀질 권리는 알권리, 표현의 자유 등 다른 기본권과 충돌할 수밖에 없기 때문에 이 권리를 법률로 구체화하는데 다각적인 학제 간 연구가 선결문제로써 검토되어야 한다. 정보 주체에게 잊혀질 권리를 법제화하는 것은 그 정보를 사용하려는 사람의 표현의 자유를 제한하는 결과를 초래하기 때문에 일정한 한계를 노출할 수밖에 없다. 현행 개인정보 보호법, 정보통신망 이용촉진 및 정보보호 등에 관한 법률 등에서 개인정보의 파기제도를 신설하여 부분적으로 잊혀질 권리를 반영하고 있지만 헌법상 중요한 가치인 잊혀질 권리와 알권리 및 표현의 자유에 대해 조화롭게 균형을 찾는 것이 선행과제인 것이다.

In the near future, robots will be used for the personal use. To provide useful services to humans, it will be necessary for robots to understand human intentions. Consequently, the development of emotional interfaces for robots is an important expansion of human-robot interactions. We designed and developed an intelligent emotional interface for the robot, and applied the interfaces to our humanoid robot, AMIET. Subsequent human-robot interaction demonstrated that our intelligent emotional interface is very intuitive and friendly
