장애인에 대한 정책과 지원, 장애인 접근성 향상을 위한 지침 제정, 기술혁신과 제품개발 등으로 장애인 보조기기 분야는 산업측면에서 크게 부각되고 있다. 최근에는 ICT 발전으로 시각 장애인용 스크린 리더, 점자 디스플레이, 화면 확대기, 문자음성 변환기 등이 출시되어 촉각과 청각으로 인터넷 접속이 용이해지고 스마트기기를 통해 편리하게 전자출판 콘텐츠를 활용하고 메일을 주고받을 수 있게 된 것이다. 그렇지만 급속하게 전환되고 있는 디지털 미디어기반의 스마트시대에 시각 장애인의 접근성은 아직도 열악하고 보조기기와 대체자료의 성능과 품질도 개선되어야 할 점이 많은 상황이다. 따라서 본 연구는 연구개발 혁신 측면에서 시각 장애인용 보조기기 및 대체자료의 현황과 구조를 분석하고 접근성 향상을 위한 구현 방향을 제시하고 있다. 연구결과, 향후에는 다양한 디지털 정보가 맞춤형 및 실감형 형태로 전환되고 장애인 전용 단말기 또는 스마트기기를 통해 유통될 것으로 예상된다.

Purpose As the smartphone market arrived at its saturation, from world leading information and communications technologies (ICT) businesses to startups, companies are competing to develop innovative wearable device products and suitable contents. Utility, technology, design, price, and various killer contents development targeting every customer's need should be considered for a success in the wearable device market. Design/methodology/approach Prior studies on innovation technology of ICT field have mainly focused on the innovation diffusion theory, expectation confirmation theory, and technology acceptance model, this study suggested the innovation resistance factors of adopting the smart wearable devices based on the innovation resistance model and theory of perceived risk. The model comprises the following two characteristics factors: 1) innovation characteristics which include perceived relative advantages, perceived compatability, perceived complexity, and perceived risk, 2) consumer characteristics which include attitudes towards innovation and existing products (i.e., mobile devices and analog watches). This study developed an extended innovation resistance model to explain the intention to acceptance of wearable devices consumers and collected 284 online survey responses from the non-consumers of the wearable devices. Findings The findings of this study suggest that perceived relative advantage, perceived compatibility, perceived complexity, perceived risk, attitudes towards innovation and attitudes towards existing analog watches affected the innovation resistance which has negative influence on the intention to adoption of wearable devices.

With the advent of the ICT era in the 4th Industrial Revolution era, cutting-edge industries in accordance with changing trends of the time, the MZ generation is leading a new consumer culture with a digital platform-based lifestyle. As such, wearable devices are leading popularization of the market, the need for product development and research that goes beyond simply combining high technology and combines user-centered functions and designs is emerging. Therefore, the purpose of this study was to analyze the functional mechanism of wearable devices according to consumption value of the MZ generation, focusing on wearable devices currently being commercialized in the digital transformation era, their characteristics were also derived. The research method for this purpose involved classifing wearable devices into notification, information, and content types according to their functional mechanisms and examing them. As a result of the research, characteristics of identity, collaboration, customization, and content were derived, I was is thought that they could interact with situational awareness to suit the situation and purpose. They are closely related. They could make social responsibility and sustainable efforts beyond the brand's image and profit pursuit. As the consumption value of the MZ generation, a new consumer class, is highlighted, it is essential to segmenting and analyzing user-centered functions and content, not simply combining cutting-edge technologies this study is significant in that it provides essential data for continuous development of wearable devices and the establishment of successful marketing strategies.

ICT 기술이 발달하며 IoT 환경이 주목받고 있다. 하지만 IoT 디바이스는 다양한 사용 용도만큼 디바이스가 동작하는 CPU의 성능도 다양하지만, 인증에 필요한 암호화가 내장되지 않은 CPU를 사용하거나, 공개키 암호가 동작하지 않는 디바이스도 다수 존재한다. 이에 따라, 본 논문에서는 램포트 해시체인, 램포트 서명, 블록체인을 분석하고, 기존 인증 프로토콜 분석을 통해 인증, 무결성 및 부인 방지 기능을 제공하는 블록체인 기반 IoT 디바이스 인증 스킴을 제안하였다. 본 논문에서 제안하는 스킴은 IoT 디바이스에 단순 해시연산만을 요구하여 저성능 IoT 디바이스에서도 동작이 가능해 IoT 환경에서 안전한 인증을 보장할 수 있다.

ICT 기술이 발달로 인하여 주변에 존재하는 사물들을 네트워크로 연결하고, 사물에 대한 정보를 이용하여 다양한 분야에서 활용하기 위한 IoT 환경이 주목받고 있으며, 보안 위협 또한 증가하는 추세이다. IoT 환경에서 증가되는 보안 문제를 해결하기 위해 민간 분야에서 인증서, 암호화, 해쉬연산, 블록체인 등을 활용한 방법들을 연구하고 있으나, 디바이스 간의 성능 격차를 극복하고 다양한 장치에서 호환성을 가지는 보안인증 방식은 현재까지 구체화 되어 제안되고 있지 않은 상황이다. 본 논문에서는 IoT 장치 환경에 따른 영향을 최소화하여 호환성을 폭넓게 확보할 수 있는 인증 방식을 제안하고자 한다.

To realize the vision of internet of things (IoT), where it is expected to bring significant impact to the global economy in the future, consideration of business models in the IoT context is necessary. This research attempts to build an enhanced artifact business model framework based on the definitions of IoT and literature on business models for analysis of IoT businesses. The framework is used to analyze four different types of players: the owner of things, vendors of devices, providers of connectivity and providers of IoT application services. The findings suggest that the owners of things tend to partner with ICT players to complement their weakness, and it tends to be connectivity providers. The device vendors leverage their strength of devices and device platforms to attract and enable 3rd party sensor/devices to interconnect, while the service providers are aiming to penetrate into customer premise. These lead to the following recommendations for non-IT players to consider in expanding into IoT business: 1) take into account differences in product development process between IT and non-IT businesses in expanding into IoT market; 2) collaborate with ICT players that acknowledge and understand the differences.

With the development of computing technology, the convergence of ICT with existing traditional industries is being attempted. In particular, with the recent advent of 5G, connectivity with numerous AuT (autonomous Things) in the real world as well as simple mobile terminals has increased. As more devices are deployed in the real world, the need for technology for devices to learn and act autonomously to communicate with humans has begun to emerge. This article introduces "Device to the Edge," a new computing paradigm that enables various devices in smart spaces (e.g., factories, metaverse, shipyards, and city centers) to perform ultra-reliable, low-latency and high-speed processing regardless of the limitations of capability and performance. The proposed technology, referred to as EdgeCPS, can link devices to augmented virtual resources of edge servers to support complex artificial intelligence tasks and ultra-proximity services from low-specification/low-resource devices to high-performance devices.

Recently, people with disabilities also search for and collect information from the web through smart devices, and save collected information on smart devices or take notes. For non-disabled people, various memo applications are provided on the market, so it is more convenient to choose according to their preference. However, existing memo services are limited for use by blind people due to the importance of visual information. The problem with blind people when using smart devices is that the screen is not recognized, so it is not possible to check in which location the menu of the application exists. In addition, it is difficult to input and manipulate text, and systematic file management and control are not possible. Therefore, in this paper, we propose the development of voice memo service that blind people can use only voice and hearing information and can operate menu with Bluetooth remote controller. We will develop a system that includes a comprehensive voice file management function for storing, searching, playing, and deleting files, rather than simply storing voice files.

Microdisplays based on organic light-emitting diodes (OLEDs) have a small form factor, and this can be a great advantage when applied to augmented reality and virtual reality devices. In addition, a high-resolution microdisplay of 3000 ppi or more can be achieved when applying a white OLED structure and a color filter. However, low luminance is the weakness of an OLED-based microdisplay as compared with other microdisplay technologies. By applying a tandem structure consisting of two separate emission layers, the efficiency of the OLED device is increased, and higher luminance can be achieved. The efficiency and white spectrum of the OLED device are affected by the position of the emitting layer in the tandem structure and calculated via optical simulation. Each white OLED device with optimized efficiency is fabricated according to the position of the emitting layer, and red, green, and blue spectrum and efficiency are confirmed after passing through color filters. The optimized white OLED device with color filters reaches 97.8% of the National Television Standards Committee standard.
