In the recent war between Ukraine and Russia, low-orbit satellite communication played a major role, and Korea laid a foothold for low-orbit satellite communication services with the successful launch of Nuri in May 2023 and entered a full-scale civilian space age competition. In order to create an ecosystem for ICT digital transformation and data convergence in the field of low-orbit satellite communication, this paper conducts user sentiment analysis by importing posts from Reddit, one of the world's SNS, and extracts need-related sentences through need mining to identify user needs, performs topic modeling to classify topics, and prepares an action plan according to these topics. We hope that this study will be used as a policy resource for the development and innovation of new business models in the field of low-orbit satellite communication, bridging the digital information gap and solving social problems, contributing to sustainable digital transformation and enhancing soft power.

This study is about technology convergence analysis of patents related to artificial intelligence technology. After defining the IPC code 'section-class' of the patent literature as one technology, the relationship between core technologies was analyzed and visualized using the social network analysis(SNA). As a result of the analysis, the core technology of artificial intelligence-related patents is G06, which has a mutual relationship with a total of 52 other technologies. Technologies with many interconnections between technologies include G06, H02, G01, G08, H04, G10, G16, and A61. Additionally, the combination with the most correlation between technologies is G06⇄H04, with G06 being a more central technology than H04. The convergence of e-commerce-related business models(G06) and communication technologies(H04) is making an important contribution to creating innovative services and products. As a result, we can confirm that artificial intelligence technology is promoting innovation and convergence in various industries, and can contribute to understanding technological trends and the direction of technological convergence.

Today, companies and social actors at the beginning of the Fourth Industrial Revolution are focusing on active innovation and efforts to adapt to rapidly changing environmental changes. Design thinking refers to creative strategies designers utilize during the process of designing. Design thinking is also an approach that can be used to consider issues and resolve problems more broadly than within professional design practice, and has been applied in business and to social issues. However, there are some limitations in the design thinking methodology during the project in the field. This paper presents a novel design - thinking process that incorporates a lean start - up based business model into the design thinking process. We conducted a case study to verify the effectiveness of our new design thinking process in social innovation projects. In this paper, it is meaningful to suggest and verify a new process that combines business model Zen to complement the limit of design thinking. It will also provide guidelines for design thinking projects as tools for social innovation.

Today, the sports teams are in a highly competitive environment where they don't know what may happen in the near future. While the front-runner teams suffer a serious slump, the teams in lower ladder stacks victories. This recent phenomenon proves that no team can secure the sustainable competitive edge over others. This is the time when a complete change of the mindset about the short-term competitive edge is needed. Therefore, we conducted the case study to the short-term competitive edges by selecting OK Savings Bank Rush & Cash volleyball team(hereafter referred to as OK Savings Bank). Thus, we presented the Transient Advantage Wave which describes the five stages of Initiating-Promotion-Utilization-Reconstruction-Withdrawal as a framework for the case study. Finally, we organized the results of the analysis and based on this result, we discussed the significance and the limitation of the short-term competitive edge that the sports team should pursue. This study contributed to the changes in strategies & tactics of various sports teams by suggesting the new strategy called short-term competitive edges that teams should utilize in order to get the best results in the sports league that has the strong quality of Time-based system.

1980년대 아날로그 이동전화서비스로 시작된 이동통신 기술은 매 10년을 주기로 빠르게 발전해 오고 있다. 디지털화를 거쳐 모바일 광대역 서비스에 초점을 맞춘 이전 세대와는 달리, 5G 이동통신서비스는 다양한 미래 정보통신 융합서비스의 플랫폼으로서, 산업구조 혁신을 통해 새로운 스마트 비즈니스 모델 및 산업 생태계를 창출하는 4차 산업혁명의 핵심 인프라로 주목받고 있다. 이러한 변화의 흐름속에서 이동통신서비스는 우리 실생활과 더욱 밀접해지고 있으나, 다른 한편으로 이동통신 환경의 취약점을 악용한 사이버 공격 위험에 노출될 가능성도 점차 확대되고 있다. 이런 배경에는 국제전기통신연합(ITU)의 IMT-2020 비전 및 요구사항을 충족시키기 위한 5G 네트워크의 구조적인 변화에 따라 공격접점이 크게 확대 되었기 때문이다. 본 고에서는 5G 시대의 도래와 함께 가장 큰 구조적 변화를 겪으며 5G 융합서비스의 핵심 인프라로서 새롭게 주목받고 있는 5G 엣지의 주요 특징을 살펴보고, 5G 엣지에서 제기되고 있는 보안위협과 이에 대한 대응 기술의 동향에 대해 살펴보고자 한다.

세계적으로 창업 생태계가 구축되면서 기술창업 분야가 두각을 보이고 있다. 기술창업은 기술력을 통한 지속력뿐 아니라 혁신적으로 변화를 진행시키므로 기술에 대한 투자 동향을 날이갈수록 높아지고 있다. 하지만 기술이 발전하면서 함께 주목되고 있는 분야가 사회적 가치를 가지고 있는 소셜벤처이다. 특히 UN에서 발표한 지속가능한 발전목표(SDGs)의 경우 필수적으로 사업 비즈니스 모델적으로 채택된 분야를 갖고 있어야하며 비재무적성과를 판단하는 기준인 ESG 또한 필수적인 사회적 가치 요소로 떠오르고 있다. 이러한 흐름 속에서 기술 역량을 내세웠을 때와 사회적 가치를 내세웠을 때 투자자들은 어떤 역량과 특성을 더 선호하며 투자 유무가 결정되는지를 분석해보고자 한다. 결국 기술 역량 또는 사회적 가치 둘중 하나를 내세운다는 것은 기업의 이미지를 나타내는것과 같은 의미이다. 이에 기술역량과 사회적 가치가 기업이미지를 유능 또는 따뜻함 중 어떻게 나타나는지 알아보고 투자 유무에 미치는 영향을 보고자 한다. 본 연구에서는 기술창업 기업 기술 범위를 인공지능(AI), 빅데이터, 사물인터넷(IoT), 바이오(Bio)로 총 4개로 분류하였다. 기술 창업의 기술범위를 독립변수로 설정하였으며 기술창업에서 기술역량 또는 사회적 특성을 내세웠을 때 기업이미지가 유능하게 보여지는지 따뜻하게 보여지는지를 알아보고자 한다. 기업이미지가 유능함 또는 따뜻함으로 비춰졌을 때 벤처투자에서 투자 유무가 결정되는지를 검증하고자 한다. 검증 방법에서는 벤처투자자가 아닌 창업교육을 이수하는 대학생들을 대상으로 모의투자를 통해 연구를 진행하고자 한다.

This paper addresses the issue of continuous user authentication within the metaverse environment. Recently, the metaverse plays a vital role in personal interaction, entertainment, education, and business, bringing forth significant security concerns. Particularly, vulnerabilities related to user identity verification have emerged as a major issue. This research proposes a novel method to verify identities by analyzing users' character movements in the metaverse through a pose estimation model. This method uses only video data for authentication, allowing flexibility in limited environments, and investigates how character movements contribute to user identification through various experiments. Furthermore, it explores the potential for extending this approach to other digital platforms. This research is expected to significantly contribute to enhancing security and innovating user identity verification methods in the metaverse environment.

Smart work is an alternative form to enable seamless business collaboration without time and space limitations using ICT. However, smart work implementation has not produced tangible achievements and sometimes has resulted in failure. This study examined users' resistance against smart work, which is regarded as one of the most important elements for the successful implementation of smart work. The study classified elements which cause users' resistance into the work's innovative characteristics and the user characteristics based on the model of innovation resistance. It also set the degree of freedom in spatial and temporal dimension as moderating factors. This empirical research results showed that low work efficiency, unfavorable evaluation methods, and high degree of satisfaction in the way of working affected smart work users' resistance. In addition, temporal freedom had a moderating effect on the relationship between users' characteristics and their resistance. On the contrary, spatial freedom affected the relationship between their works' innovative characteristics and their resistance. The study results suggest that organizations need to set up business processes and evaluation methods first to adopt Smart work successfully.
