1999 년부터 상용화된 무선 인터넷 서비스는 국내의 경우 이동통신 3 사가 각기 독자적인 통신 기법 및 서비스 체제를 가지고 있었다. 이로 인하여 서로 다른 이동통신사의 무선 단말기 플랫폼들은 상호 호환성(interoperability)이 없었다. 이러한 비호환성은 단말기 제조업체나 컨텐츠 제작 업체에게 기술적인 어려움은 물론이고 비용적인 측면에서 여러 가지 문제점을 낳았다. 이러한 문제점을 해결하고자 2002 년부터 WIPI(Wireless Internet Platform for Interoperability)라는 표준화된 무선 인터넷 플랫폼의 개발이 시작되어 현재는 WIPI 2.0 을 탑재한 무선 단말기가 출시된 상황이다. 본 논문에서는 WIPI 플랫폼이 탑재된 무선 단말기가 유료화된 컨텐츠를 다운로드 하여 사용할 수 있도록 해주는 다운로드 시스템의 설계 및 구현에 대해서 기술한다. 이를 위해 컨텐츠 다운로드 프로토콜, 최적화된 컨텐츠의 결정기법, 그리고 COD(Compile On Demand)를 이용한 네이티브 코드 적용 기법에 대해 설명한다.

The purpose of this study was to quantitatively observe changes in postural stability of double leg support and single limb stance. Thirty-six healthy subjects participated in the study. Postural stability were examined using Dynamic Balance System. Each trial was 25 sec in duration. Each of 6 conditions{double leg support and single limb stance ; eyes open in stable platform, eyes closed in stable platform, eyes open in dynamic platform) evaluated effect of visual, vestibular, proprioceptive system. Center of balance found for displacement to the left along the X axis in double leg support and to the forward on left toe in single limb stance. Sway index was the lowest in double leg support with eyes open in stable platform and the higher in single limb stance with eyes closed in stance platform. We believe that reliable and valid measures should be used to determine the contributing factors of our client's postural problems so that we can design the most effective treatment possible.

In this paper, the implementation of creative engineering robot with MCU platform is described. This robot, as a platform of robot system to be used as creative engineering education, has to satisfy restrictions in many aspects in order to study algorithm and apply for the processor based function and pattern recognition application. Considering many restrictions of the mobile platform for creative robot system, we made this robot autonomous by using efficiently the LINUX embedded system. And we choose Marvell Monahan processor(PXA320) as MCU flatform, and used CentOS5.2 as an embedded OS that has the function of robustness and optimality. For flexibility and modularity, the platform has expansion ports. The results of experiment are described to show the pattern matching of creative engineering mobile robot with LINUX programming environments.

In this paper the platform system for IEEE 802.15.4 Low Rate WPAN is designed and fabricated. IEEE 802.15.4 Low Rate WPAN system serves the functions and realization of home-area network. According to the IEEE 802.15.4 standard, there are two modes, One is BPSK modulation in 868/915MHz frequency band. The other is O-QPSK modulation in 2.45GHz frequency band. In this paper we implemented the platform system mounted in one PCB board in 868/915MHz frequency band of IEEE 802.15.4 Low Rate WPAN system. We measured that the platform system which consists of digital part and RF part has good performance. Also RF part is realized by design and fabrication of the RF transceiver IC. The key issue is to make the platform system which provides the function of Low Rate WPAN system to meet the requirement of IEEE 802.15.4 standards.

Due to the development of science and technology and the emergence of new industries, the environmental change of the digital contents industry is rapidly progressing. The scope of technological development in the digital contents industry is affecting not only the entertainment industry but also various industries. Recently, with the development of digital convergence using realistic content, games, video, and VR have provided new opportunities for the growth of the content industry. The researcher determined that a new education system would need to be changed as the digital contents industry developed. For this purpose, an AHP questionnaire was conducted for experts with a high basic understanding of the education platform based on previous studies. We proposed a platform model for human resource development as an education system that meets the demand of digital contents industry. The education system for nurturing talents needed by future society should include elements that can interest the learning of users. The platform should not be approached from a system point of view, but should be developed from the content and user's point of view, considering the platform's original purpose.

In this paper, we present a certificate management platform for performance assessment during recruitment using blockchain. Applicants are awarded certificates according to a predetermined level of progress based on their performances. All certificates are stored on a recruitment management platform that serves as an environment for storing and presenting all awarded certificates. The hashed information of all the certificates are stored in the blockchain, and once stored, the contents cannot be tampered with. Therefore, anyone can check the validity of the certificates using this blockchain. Our proposed platform will be useful for recruitment and application management, career management, and personal history maintenance.

The recent efforts in academia and industry represent a paradigm shift that will extend the IoT from the home environment so that it is interoperable with the Internet of Vehicles (IoV). IoV is a special kind of IoT. It allows to connect between vehicle and things located in infrastructure. Furthermore, IoV enable to create new intelligent services through collaboration with existing various services such as smart city and connected home. In this paper, we develop a service in order to realize IoV. To this end, we design a novel vehicle service platform which could automatical controlling the IoT device according to drivers' voice. To show practical usability of our proposed platform, we develop a prototype service could be call car-to-thing (C2T). We expect that our proposed platform could eventually contribute to realizing IoV.

Owing to the environment in which it has become difficult to face people, on-tact communication has been activated, and online video conferencing platforms have become indispensable collaboration tools. Although costs have dropped and productivity has improved, communication remains poor. Recently, various companies, including existing online videoconferencing companies, have attempted to solve communication problems by establishing a videoconferencing platform within the virtual reality (Virtual Reality) space. Although the VR videoconference platform has only improved upon the benefits of existing video conferences, the problem of manually summarizing minutes because there is no function to summarize minute documents still remains. Therefore, this study proposes a method for establishing a meeting minute summary system without applying cases to a VR videoconference platform. This study aims to solve the problem of communication difficulties by combining VR, a metaverse technology, with an existing online video conferencing platform.
