In the mobile phone map service there are some restrictions of resolutions and process in terminals. So providing a sketch map is very efficient. This simplifies the map data and increases the understanding of the user. This sketched map marks the starting point and ending point. Then simplifies the surroundings like important roads or building so the user can find his/her way easily. First of all this sketch map service needs a method to simplify the route between starting point and ending point and the surroundings. After that it needs to make the simplified data into a sketch map and suitable to the terminal's resolution. To solve these problems this paper proposes a new method to manifest a sketch map efficiently through a mobile phone. The method, introduced in this paper, is surveyed to have a higher efficiency in data usage compared to the current services available in the market. And also it is examined to have a clear vision in process and easily understandable.

Virtual Reality(VR) technology is an interface technology that is actively used in various audio-visual-based applications by showing users a virtual world composed of computer graphics. Since VR-based applications are graphic processing-based applications, expensive computing devices equipped with Graphics Processing Unit(GPU) are essential for graphic processing. This incurs a cost burden on VR application users for maintaining and managing computing devices, and as one of the solutions to this, a method of operating services in cloud environments is being used. This paper proposes a performance management technique to address the problem of performance interference between containers owing to GPU resource competition in container-based high-performance cloud environments in which multiple containers share a single GPU. The proposed technique reduces performance deviation due to performance interference, helping provide uniform performance-based remote VR services for users. In addition, this paper verifies the efficiency of the proposed technique through experiments.

The purpose of this study was to explore ways a digital therapeutics-based community care plans for the rehabilitation in dysarthria in a situation where non-face-to-face services are expanding in the COVID-19 era. To this end, a qualitative study was conducted on experts working in hospitals, speech-language pathology centers, and social welfare centers, and as a result of the study, 3 topics, 9 sub-themes, and 18 content units were derived. Based on the analysis results, the digital therapeutics-based community care model consisted of 9 types: remote diagnosis, telepractice, rehabilitation training program, peer supporters, clinical support, communication, psychosocial intervention, and care plan services. This study will be able to provide basic data for health care & welfare services using digital therapeutics and guidelines for establishing shared care plans based on multidisciplinary cooperation.

Machine-to-Machine (M2M) communication provides each component (machine) with access to Internet, evolving into the IoT technology. IoT is a trend where numbers of devices provide the communication service, using the Internet protocol. As spreading the concept of IoT(Internet of Things), various objects become home information sources. According to the wide spread of various devices, it is difficult to access data on the devices with unified manners. Under this environment, security is a critical element to create various types of application and service. In this paper propose the inter-device authentication and Centralized Remote Security Provisioning framework in Open M2M environment. The results of previous studies in this task is carried out by protecting it with the latest information on M2M / IoT and designed to provide the ultimate goal of future M2M / IoT optimized platform that can be integrated M2M / IoT service security and security model presents the information.

This study focuses on enhancing the understanding of the form and characteristics of traditional towers, or 'pagodas,' by utilizing WebXR technology to enable users to explore 3D models and experience them in virtual reality on the web. Traditional towers in Korea pose challenges for direct on-site verification due to their size, making it difficult to examine the structure and features of each level. To address these issues, this research aims to provide users with a WebXR service that allows them to remotely explore and analyze towers without geographical or temporal constraints. The research methodology involves utilizing WebAR to offer a web-based service where users can directly view the original form of the tower's 3D model using smart devices both online and on-site. However, outdoor conditions may affect performance, and to address this, a tower-outline detection and matching technique was employed. Consequently, we propose a remote support service for traditional towers, allowing users to remotely access information and features of various towers nationwide on the web. Meanwhile, on-site visits can involve experiencing augmented reality representations of towers using smart devices.

In this paper, the u-Service system that is based on location-aware technology is designed and implemented for a silver town. On the real silver town the developed system has been employed and tested to provide convenient and secure living for residents. It provides services such as emergency call, intelligent elevator operation, and hands-free door access based on the location of the residents with personal device as called smart tag. It can also be applied to other service areas such as the location-aware u-Service for hospital, high-rising complex building, APT, etc.

최근, 임상연구는 유비쿼터스 헬스케어 서비스를 이용한 환자 개인의 맞춤형 의료 서비스에 관한 연구가 진행되고 있다. 유비쿼터스 헬스케어 서비스 시스템은 원격의 환자를 유무선 네트워킹 기술을 활용하여 "언제 어디서나" 이용 가능한 의료서비스를 제공할 수 있다. 이러한 기술들 덕택에, 의료 서비스가 의료기관 내에서 실-생활 영역으로 공간적인 확대와 특정 질병치료에서 평생 건강관리로 시간적인 확대가 가능해졌다. 본 논문에서는 유비쿼터스 환경에서 환자와 전문의가 실시간으로 상호작용을 통해 최적의 의료서비스 제공할 수 있는 유비쿼터스 헬스케어 서비스 기반의 과민성 방광 환자 관리 시스템을 설계하고 구현하였다.
