This study looked through the text mining analysis to check the status of the virtual assistant service, and explore the needs of consumers, and present consumer-oriented directions. Trendup 4.0 was used to analyze the keywords of AI services in Online News and social media from 2016 to 2020. The R program was used to collect consumer comment data and implement Topic Modeling analysis. According to the analysis, the number of mentions of AI services in mass media and social media has steadily increased. The Sentimental Analysis showed consumers were feeling positive about AI services in terms of useful and convenient functional and emotional aspects such as pleasure and interest. However, consumers were also experiencing complexity and difficulty with AI services and had concerns and fears about the use of AI services in the early stages of their introduction. The results of the consumer review analysis showed that there were topics(Technical Requirements) related to technology and the access process for the AI services to be provided, and topics (Consumer Request) expressed negative feelings about AI services, and topics(Consumer Life Support Area) about specific functions in the use of AI services. Text mining analysis enable this study to confirm consumer expectations or concerns about AI service, and to examine areas of service support that consumers experienced. The review data on each platform also revealed that the potential needs of consumers could be met by expanding the scope of support services and applying platform-specific strengths to provide differentiated services.

AI blockchain technology, which is attracting attention as a core technology of the 4th Industrial Revolution, is a technology that can be used as an important means of innovation not only in the current gaming industry but also in various industrial fields. This paper extracts the platforms and types of blockchain games currently ranked within the top 100 on the blockchain app (DApp) sites State Of The DApps, DApp.com, and Dapp Rader and introduces the top games on major platforms. As a result of extracting platforms and types, the top games were mainly based on Ethereum, EOS, and Steam. However, the results showed that there are significantly more games based on the Ethereum platform, which are stable, easy to apply, and have a low barrier to entry due to the large number of users and DApps. We plan to improve awareness of blockchain games by studying the characteristics that only blockchain games have.

The purpose of this study is to prove the Korean Internet company, Kakao's resilience capacity. For it, this paper reviews the previous literatures regarding Kakao's business models and discusses 'resilience' theory. Then, it organizes the research questions based on the theoretical background and explains the research methodology. It investigates the case of Kakao's business and organization. The case analysis shows that five levers of resilience are a good indicator for a successful platform business evolution. The five levers are composed of coordination, cooperation, clout, capability, and connection: First lever, coordination that makes the company to restructure its silo governance in order to respond to actual business flow starting from the basic asset like game and music content; second lever, cooperation where the firm provides creative people with playground for startups such as KakaoPage; third lever, clout where the company shares its data by opening its API of AI and chatbot to $3^{rd}$ party developers; fourth lever, capability where the firm establishes AI R&D center, KakaoBrain as the function of multi-domain generalist for developing diverse platforms tackling customer needs; and the last fifth lever, connection where the firm continues to expand its platform business to the peripheries, O2O businesses such as KakaoTaxi, KakaoOrder, KakaoPay, and KakaoBank. In conclusion, this study proposes Internet companies to be a resilient platform utilizing those five levers of resilience in order to form successful platform. This study contributes to the agile innovation of Internet platform with ecological sense.

This paper proposes a novel safety autonomous platform (SAP) architecture that can automatically and precisely manage on-site safety through ensemble artificial intelligence models generated from video information, worker's biometric information, and the safety rule to estimate the risk index. We practically designed the proposed SAP architecture by the Hadoop ecosystem with Kafka/NiFi, Spark/Hive, Hue, ELK (Elasticsearch, Logstash, Kibana), Ansible, etc., and confirmed that it worked well with safety mobility gateways for providing various safety applications.

This literature review explores artificial intelligence (AI) technology trends and IBM Watson health and medical references. This study explains how healthcare will be changed by the evolution of AI technology, and also summarizes key technologies in AI, specifically the technology of IBM Watson. We look at this issue from the perspective of 'information overload,' in that medical literature doubles every three years, with approximately 700,000 new scientific articles being published every year, in addition to the explosion of patient data. Estimates are also forecasting a shortage of oncologists, with the demand expected to grow by 42%. Due to this projected shortage, physicians won't likely be able to explore the best treatment options for patients in clinical trials. This issue can be addressed by the AI Watson motivation to solve healthcare industry issues. In addition, the Watson Oncology solution is reviewed from the end user interface point of view. This study also investigates global company platform business to explain how AI and machine learning technology are expanding in the market with use cases. It emphasizes ecosystem partner business models that can support startup and venture businesses including healthcare models. Finally, we identify a need for healthcare company partnerships to be reviewed from the aspect of solution transformation. AI and Watson will change a lot in the healthcare business. This study addresses what we need to prepare for AI, Cognitive Era those are understanding of AI innovation, Cloud Platform business, the importance of data sets, and needs for further enhancement in our knowledge base.

COVID-19의 장기화는 다양한 산업의 패러다임에 새로운 시도와 변화를 주고 있다. 고객이 직접 피우에 닿고 사용하는 제품을 판매하는 산업에서는 그 현상이 날로 가중된다. 이러한 상황에 대응하고자 최근 Cosmetics 업계에서 다양한 언택트(비대면) 서비스들을 선보이고 있다. 기존 전통 오프라인 채널에서부터 다양한 온라인 채널 확보를 통하여 고객들의 수요와 참여를 끌어내고자 한다. 대표적으로 기존에는 온라인 문진 서비스를 이용하여 고객에게 맞춤 제품을 추천하는 서비스들을 제공하고 있지만 얼마 지나지 않아 한계에 도달하게 된다. 본 논문에서는 기존 정형화된 문진 서비스와 한걸음 더 나아가 AI 기술을 이용한 이미지 기반 피부진단 기능을 결합하는 새로운 방식의 피부진단 서비스에 대하여 연구하였다. 사용자는 촬영된 이미지를 이용하여 몇 가지 항목에 대한 진단을 받게 되고 최종 피부타입을 도출하기 위하여 부족한 진단 항목은 기존에 제안한 피부진단 서비스를 활용하였다. 이런 방식은 기존에 제공되고 있는 문진 서비스보다 재미 요소를 더할 뿐만 아니라 기술 트린드인 AI를 결합하여 더욱 고객 참여를 이끌어 낼 수 있고 가시적이고 정확도가 있는 지속적인 서비스를 만들어 내고자 함에 있다.

We look at the business model development of a fan community platform 'Weverse' from two-sided platform (TSP) to multi-sided platform (MSP) and investigate its platform business model. From the Rocket Model's theoretical perspective, the results reveal that Weverse firstly focuses on inviting artists as many as possible starting from BTS, then attracts new artists' fans naturally. For success of this TSP, it forms MSP, 'Weverse Shop' to meet two sides' relevant needs timely and filtered. In third stage of connection, various partnerships are attempted in terms of open platform strategies. For instance, by combining 'VLive' and Weverse, Naver's fan platform business is transferred to Weverse. For core transaction through direct and indirect monetization, several cobranding activities are tried. Lastly, regarding optimization, newly born Weverse being launched in the first half of 2022 is supposed to create further synergies with Naver's R&D capabilities in data, AI, and other technologies like metaverse platform 'ZEPETO' which already sells clothing items of Weverse artists.

최근 글로벌 플랫폼 서비스사업자가 제공하는 플랫폼 서비스의 장애로 전 세계적으로 특정 콘텐츠 서비스가 불가한 상황이 발생하고, 글로벌 서비스 시장에 사회 경제적으로 상당히 큰 문제를 초래하고 있다. 플랫폼 서비스의 안정성 확보를 위해서는 지능화된 플랫폼 운용 관리가 요구된다. 또한, 플랫폼 장애를 사전에 예방하고 대응할 수 있는 지능형 관리 기술이 필요하다. 본 연구에서는 플랫폼 운용 환경에서 비정상적인 서비스 상태 및 장애를 신속하게 감지 대응하기 위한 플랫폼 빅데이터 플로우 관리 기법 및 관리 모듈 구현 방안을 제안하였다. 서비스 및 장애 상황 감시 특성 분석 결과 빅데이터 플로우 관리 기법이 장애 감시 측면에서 전통적인 네트워크 관리 방법에 비하여 비정상적인 장애 상황 감지 및 장애 대응 특성이 30%이상 개선됨을 확인하였다. 빅데이터 플로우 관리 방법의 경우 플랫폼 시스템 장애 및 비정상적인 서비스 상태를 신속하게 감지할 수 있는 장점이 있으며 AI 기반 기술과 연계시 플랫폼 관리를 지능적으로 수행하고 장애 예방보전 능력은 크게 향상될 수 있을 것으로 기대된다.
