Artificial intelligence is becoming a global hot topic and is being actively applied in various industrial fields. Not only is artificial intelligence being applied to industrial sites in an on-premises method, but cloud-based artificial intelligence platforms are expanding into "as a service" type. The purpose of this study is to develop and verify a measurement tool for an evaluation framework for the adoption of a cloud-based artificial intelligence platform and test the interrelationships of evaluation variables. To achieve this purpose, empirical testing was conducted to verify the hypothesis using an expanded technology acceptance model, and factors affecting the intention to adopt a cloud-based artificial intelligence platform were analyzed. The results of this study are intended to increase user awareness of cloud-based artificial intelligence platforms and help various industries adopt them through the evaluation framework.

Recently, artificial intelligence techniques have been widely used in the computer science field, such as the Internet of Things, big data, cloud computing, and mobile computing. In particular, resource management is of utmost importance for maintaining the quality of services, service-level agreements, and the availability of the system. In this paper, we review and analyze various ways to meet the requirements of cloud resource management based on artificial intelligence. We divide cloud resource management techniques based on artificial intelligence into three categories: fog computing systems, edge-cloud systems, and intelligent cloud computing systems. The aim of the paper is to propose an intelligent resource management scheme that manages mobile resources by monitoring devices' statuses and predicting their future stability based on one of the artificial intelligence techniques. We explore how our proposed resource management scheme can be extended to various cloud-based systems.

In the smart industry where data plays an important role, cloud computing is being used in a complex and advanced way as a convergence technology because it has and fits well with its strengths. Accordingly, in order to utilize artificial intelligence rather than human beings for quality management of cloud computing services, a consistent standardization method of data collected from various nodes in various areas is required. Therefore, this study analyzed technologies and cases for incorporating artificial intelligence into specific services through previous studies, suggested a plan to use artificial intelligence to comprehensively standardize data in quality management of cloud computing services, and then verified it through case studies. It can also be applied to the artificial intelligence learning model that analyzes the risks arising from the data formalization method presented in this study and predicts the quality risks that are likely to occur. However, there is also a limitation that separate policy development for service quality management needs to be supplemented.

모바일 엣지 클라우드 환경에서 중요하게 다루어야 할 사항 중 하나는 모바일 장치에 대한 모니터링이다. 모바일 장치는 장치의 특성상 불안정한 상태가 발생하여 결함이 발생할 수 있기 때문에 모바일 엣지 클라우드의 SLA (Service Level Agreement)를 만족시키기 위해서는 모바일 장치의 모니터링 기법을 통해 결함을 측정하여 이에 대한 조치를 수행하여야 한다. 이 논문에서는 모바일 엣지 클라우드 환경에서 인공지능 기반 모바일 장치 모니터링 기법을 제안한다. 제안하는 모니터링 기법은 모바일 장치에 대한 이전 모니터링 정보와 현재 모니터링 정보를 기반으로 모바일 장치의 결함 발생을 측정할 수 있도록 설계 되었다. 이를 위해 인공지능 기법 중 하나인 은닉 마르코프 체인 모델을 모바일 장치에 대한 모니터링 기법에 적용하였다. 실험 평가를 통해 제안하는 모니터링 기법에 대한 검증을 수행하였다. 제안하는 기법은 모바일 장치뿐만 아니라 일반적인 클라우드 환경에서의 가상 머신을 모니터링 하는 방법으로도 활용할 수 있도록 설계되었다.

인공지능을 이용하여 예측이나 분석하는 기술은 지속적으로 발전하고 있지만, 의사결정 과정을 명확히 해석하지 못하는 블랙박스 문제가 존재한다. 따라서 인공지능 모델의 의사결정 과정에서 사용자의 입장에서 해석이 불가능하여 결과를 신뢰할 수 없는 문제가 발생한다. 본 연구에서는 인공지능의 문제점과 이를 해결하기 위한 블록체인을 활용한 설명 가능한 인공지능에 대해 연구를 진행하였다. 블록체인을 이용해서 설명 가능한 인공지능 모델의 의사결정 과정에서의 데이터를 타임스탬프 등을 이용하여 부분별로 블록체인에 저장한다. 블록체인을 이용하여 저장된 데이터의 위변조 방지를 제공하고 블록체인의 특성상 사용자는 블록에 저장된 의사결정 과정등의 데이터를 자유롭게 접근할 수 있다. 설명 가능한 인공지능 모델의 구축이 힘든 것은 기존 모델의 복잡성이 큰 부분을 차지한다. 따라서 포인트 클라우드를 활용해서 3차원 데이터 처리와 가공과정의 효율성을 높여서 의사결정 과정을 단축해 설명 가능한 인공지능 모델의 구축을 원활하게 한다. 블록체인에 데이터 저장과정에서 데이터 위변조가 발생할 수 있는 오라클 문제를 해결하기 위해 저장과정에 중간자를 거치는 블록체인 기반의 설명 가능한 인공지능 모델을 제안하여 인공지능의 블랙박스 문제를 해결하였다.

With the vision of Internet of Things (IoT), physical world itself is becoming a connected information system on the Internet and cyber world is computing as a physical act to sense and respond to real-world events collaboratively. The systems that tightly interlink the cyber and physical worlds are often referred to as Smart Systems or Cyber-Physical Systems. Smart IoT Clouds aim to provide a cyber-physical infrastructure for utility (pay-as-you-go) computing to easily and rapidly build, modify and provision auto-scale smart systems that continuously monitor and collect data about real-world events and automatically control their environment. Developing specifications for service interoperability is critical to enable to achieve this vision. In this paper, we bring an issue to extend Open Cloud Computing Interface for uniform, interoperable interfaces for Smart IoT Cloud Services to access services and build a smart system through orchestrating the cloud services.

The role of artificial medical intelligence through medical big data has been focused on data-based medical device business and medical service technology development in the field of diagnostic examination of the patient's current condition, clinical decision support, and patient monitoring and management. Recently, with the 4th Industrial Revolution, the medical field changed the medical treatment paradigm from the method of treatment based on the knowledge and experience of doctors in the past to the form of receiving the help of high-precision medical intelligence based on medical data. In addition, due to the spread of non-face-to-face treatment due to the COVID-19 pandemic, it is expected that the era of telemedicine, in which patients will be treated by doctors at home rather than hospitals, will soon come. It can be said that artificial medical intelligence plays a big role at the center of this paradigm shift in prevention-centered treatment rather than treatment. Based on big data, this paper analyzes the current status of artificial intelligence technology for chronic disease patients, market trends, and domestic and foreign company trends to predict the expected effect and future development direction of artificial intelligence technology for chronic disease patients. In addition, it is intended to present the necessity of developing digital therapeutics that can provide various medical services to chronically ill patients and serve as medical support to clinicians.

Cloud service has the characteristic that it must be always available and that it must be able to respond immediately to user requests. This study suggests a method for constructing a proactive and autonomous quality and performance management system to meet these characteristics of cloud services. To this end, we identify quantitative measurement factors for cloud service quality and performance management, define a structure for applying a time series framework to cloud service application quality and performance management for proactive management, and then use big data and artificial intelligence for autonomous management. The flow of data processing and the configuration and flow of big data and artificial intelligence platforms were defined to combine intelligent technologies. In addition, the effectiveness was confirmed by applying it to the cloud service quality and performance management system through a case study. Using the methodology presented in this study, it is possible to improve the service management system that has been managed artificially and retrospectively through various convergence. However, since it requires the collection, processing, and processing of various types of data, it also has limitations in that data standardization must be prioritized in each technology and industry.

최근 스마트 물류, 핀테크, 엔터테인먼트 등 다양한 산업 분야의 인공지능 워크로드들이 클라우드 상에서 실행되고 있다. 본 논문은 이기종 GPU 클러스터로 구성된 다중 테넌트 클라우드 시스템에서 다양한 인공지능 워크로드가 실행될 때 발생하는 스케줄링 문제를 다룬다. 전통적인 스케줄링은 이러한 환경에서 GPU 이용률을 크게 저하시켜 시스템의 성능을 떨어뜨린다. 이러한 문제를 해결하기 위해, 본 논문에서는 유전 알고리즘 기반의 최적화 기법을 사용하는 새로운 스케줄링 접근 방식을 제안하고, 이를 프로세스 기반 이벤트 시뮬레이션 프레임워크에 구현하였다. 알리바바의 MLaaS 클러스터에서 수집한 광범위한 인공지능 작업들의 트레이스를 재현하는 실험을 통해 제안하는 스케줄링이 기존 스케줄링에 비해 GPU 이용률을 크게 개선함을 확인하였다.
