The blockchain is still new and unfamiliar. But blockchain appears to shake an entire technology innovation system. Blockchain is rapidly drawing attention in that it will be able to fundamentally revolutionize industry ecosystem. While cryptocurrency transactions and market capitalization have been popular in mass media, several platform operators in non-cryptocurrency areas such as jewelry, social networks, and entertainment, are also moving to introduce blockchain technology in full swing. In this brief note, we intend to present integrated theoretical strands to summarize various prospects for blockchain technology. Further, we want to provide a reflection as to whether this new technology gives opportunities, challenges, or risks to future society. Particularly, we point out one of its alternative and promising adoption that gives way to new forms of decentralized and autonomous organizations (DAOs).

거래 시 발생하는 잔돈들로 인해 이용자들은 소지의 불편함이 있고 서랍속에서 잠자고 있는 동전들로 인해 연간 수억 원의 동전 발행 비용이 발생하고 있다. 본 시스템은 스마트 기기들을 이용한 사용자들을 대상으로 잔돈을 적립하여 기부하기, 선물하기, 구매하기 등의 시스템을 설계하고 이를 테스트하였다. 본 시스템은 기본적인 잔돈 적립 및 소비 기능 외에 가맹점이 확보되지 않은 상태에서 사용자 앱을 테스트할 수 있도록 설계한 부분과 SNS와 연계되어 커뮤니티를 활용할 수 있다는 것이 특이점이다. 본 시스템을 통해서 이용자들의 편의성과 만족, 동전 발행이라는 사회적 비용 절감, 기부문화의 확산 등을 기대하고 있다.

Baotu Spring Park, a must-visit place in Jinan, China, has been rated as the country's highest-level scenic spot by the Chinese government. However, social media that highly reflects public opinions tends to express a lower evaluation of Baotu Spring Park. Thus, this paper employs service design thinking methods to identify the problems of Baotu Spring Park and provide solutions from the perspective of visitors. Based on desk research, tourist behavior tracking, contextual interviews, and a customer journey map, it was found that the service gap of Baotu Spring Park lacks a unified and effective instruction system. Also, the activities, parking, and high-quality tourist souvenirs are deficient, and there is no online information delivery platform. Finally, five suggestions are made,-respectively:,- redesign the sign system, enhance the participation of tourists, redesign the tourist souvenirs and display space, offer parking areas and shuttle buses, as well as set up a dedicated application.

Because of the development and spread of artificial intelligence (AI) technology, new security threats and adverse AI functions have emerged as a real problem in the process of diversifying areas of use and introducing AI-based products and services to users. In response, it is necessary to develop new AI-based technologies in the field of information protection and security. This paper reviews topics such as domestic and international trends on false information detection technology, cyber security technology, and trust distribution platform technology, and it establishes the direction of the promotion of technology development. In addition, the development of international trends in ethical AI guidelines to ensure the human-centered ethical validity of AI development processes and final systems in parallel with technology development are analyzed and discussed. ETRI has developed AI policing technology, information protection, and security technologies as well as derived tasks and implementation strategies to prepare ethical AI development guidelines to ensure the reliability of AI based on its capabilities.

This paper traces the issue of key account management success which has regarded as a pressing concern of many companies' sales efforts at the organizational business-to-business context. Based on the extensive review of extant literatures, we introduced a theoretical framework that covers the antecedents and consequence of key account management success. We theorized the conditions under which organizational and relational factors influence the success of key account management approach. We endeavor to develop research propositions for each construct and provide necessary suggestions to isolate a platform for future empirical research. Beyond this span, an improved understanding from this framework will help developing policies for successful key account management approach.

The main goal of e-learning systems is just-in-time knowledge acquisition. Rule-based e-learning systems, however, suffer from the mesa effect and the cold start problem, which both result in low user acceptance. E-learning systems suffer a further drawback in rendering the implementation of a natural interface in humanoids difficult. To address these concerns, even exceptional questions of the learner must be answerable. This paper aims to propose a method that can understand the learner's verbal cues and then intelligently explore additional domains of knowledge based on crowd data sources such as Wikipedia and social media, ultimately allowing for better answers in real-time. A prototype system was implemented using the NAO platform.

신문을 활용하는 교육 방식을 NIE(Newspaper in Education)라고 한다. 매일 새로운 정보가 실리는 신문을 활용함으로써 교육적인 효과를 볼 수 있다. 신문 활용의 교육적인 장점으로 고등학교 사회과 수업에서 신문은 읽기 형태의 교재로 쓰이고 있다. 그런데 최근 인터넷의 발전으로 NIE활동에 온라인 신문의 활용이 늘고 있다. 하지만 온라인 신문을 교육에 활용하는 데는 몇 가지 문제점이 있다. 첫째, 신문을 직접 수집하는 자체의 번거로움. 둘째, 온라인에서 제공되는 신문에는 광고와 같은 노이즈에 노출이다. 마지막으로 인터넷 특성상 신뢰성이 낮은 정보가 많다는 점이다. 이러한 문제점을 해결하기 위해 본 논문은 온라인 신문기사를 문서형태로 수집하고 제공하는 시스템을 구현했다. 수집 시스템에 의해 저장된 기사는 구성주의 학습을 위한 온라인 토론학습 활동을 위해 쓰인다. 따라서 본 연구는 고등학교 사회과 NIE활동에 양질의 기사 정보를 제공하고 편리함을 주어 학습효과를 높이기 위한 시스템의 구현을 목표로 했다.

As social interest in the metaverse increases, various metaverse platforms and services are appearing, and various security issues are emerging accordingly. In particular, since all activities are performed in a variety of virtual spaces, and the metaverse utilizes sensing data using various hardware devices, more information is accumulated than other Internet services, and more damage can occur if information security is not guaranteed. Therefore, in this paper, we propose a metaverse security model that considers the major issues mentioned in previous papers and the necessary evaluation factors for the security functions required in the metaverse platform. As a result of performing the performance evaluation of the proposed model and the existing attribute information collection model, the proposed model can provide security functions such as anonymity and source authentication, which were not provided by the existing models.

Since the announcement of bitcoin, new cryptocurrencies have been launched steadily and blockchain technology is also evolving with cryptocurrcies. In particular, security-related technologies such as consensus algorithm and hash algorithm have been improved and transaction processing speed has also been drastically improved to a level that can replace a centralized system. In addition, the advent of smart contract technology and the DApp platform also provides a means for cryptocurrency to decentralize social services beyond just payment. In this paper, we first describe the technologies for implementing cryptocurrency. And the major cryptocurrencies are described with a focus on the technical characteristics. In addition, the development of cryptocurrency technology is expanding the scope of use, so we tried to introduce various cryptocurrencies.

본 논문에서는 인공지능과 빅데이터 클라우드 등 다양한 4차 산업혁명시대의 기술과 교육을 융합한 에듀테크를 기초로 하여 에듀테크에 대한 교사의 학습 방향을 제시하며 전체적인 클라우드의 개념 및 분류체계, 교육의 활용을 제시하였고 클라우드 기반 교육용 소셜 플랫폼과 R. M. Gagne(1985)의 9가지 이론을 토대로 정보교과 추상화 단원의 학습 지도안을 설계 후 성취도 평가를 제시하였다. 연구 내용 분석 결과 기술의 발전성과 교육현장에서의 개인정보 교육 및 정보보안 교육의 필요성이 강조되며 확고한 플랫폼 구축과 빅데이터 확보 및 분석하여 개인에게 맞춤형 서비스 제공이 필요하다. 또한 사용자 편의성 극대화 서비스 및 UX 간결이 요구된다. 본 논문을 토대로 에듀테크의 일부분인 클라우드 기반 소셜러닝의 다양하고 체계적인 선행연구 활성화에 시발점이 되었으면 한다.
