Recently, many companies are interested in adopting cloud computing as their IT strategy. However, no distinct results have appeared in the substantial implementation of this technology. The main reason for such result is from the absence of research models leading to high impact studies on cloud computing. Thus, this study attempts to find a possible answer for the following research question : what factors influence an organizational assimilation of cloud computing? This study investigates Technology-Push (TP)/Need-Pull (NP) theory as a main factor affecting cloud computing assimilation. Also, the study examines the moderating role of organizational readiness. TP includes of perceived benefits, vendor pressure, cost savings, and IT activity intensity while NP includes competitor orientation, information technology policy, technological turbulence, and performance gaps. In addition, organizational readiness suggests two variables, financial resources and technological knowledge. Result from 217 adopting organizations showed that all of these factors with exception of competitor orientation and vendor pressure, have statistically significant impact on assimilation of cloud computing. The implications of the findings propose a theoretical framework for the foundation of studies on cloud computing assimilation, which can server as important practical guidelines for technology development.

무크(Mook) 서비스 정착과 교육부의 원격 수업 확대 정책에 힘입어 대학을 중심으로 온라인 수업이 일반화하고 있으며, 출석 정규 수업의 형태도 일부 원격 방식으로 전환되는 추세이다. 본 논문은 이러한 교육 환경에서 필요한 교육용 콘텐츠를 제작하는 도구에 관한 것으로 이에 필요한 오디오 동기화 방법과 편집 알고리즘을 제안하였다. 제안한 알고리즘을 노트북 등 일반적인 PC 환경에서 그 성능을 측정하였다. 평가 결과, 안정적인 CPU와 Ram 사용량을 보였다. CPU 사용은 평균 9.3% 점유율을 나타냈고 Ram은 평균 87Mega바이트의 안정적인 사용량을 기록하였다(CPU 2.60GHz, 820*600 영역 기준). 본 제안하는 방식을 사용하면 손쉽게 자기 PC로 원격교육을 진행할 수 있을 것으로 판단된다.

The article proposes a methodical approach to assessing the innovative capacity of agri-food enterprises. This approach is based on the calculation of personnel, investment, technical and technological, information components of the ability of agri-food enterprises to innovate. The algorithm of search of production, intellectual, financial, information resources reserves, which are necessary for functioning of the enterprises of agro-food sphere, is defined. The approach developed by the authors, in contrast to the existing ones in the scientific world, allows the tools of mathematical modeling to identify shortcomings in the development of agri-food enterprises, to forecast the development of these enterprises and on this basis to form different models of market stakeholders. The method proposed by the authors to assess the innovative capacity of agri-food enterprises allows market participants to assess the current state of agri-food enterprises and form the necessary management levers to influence its activities to eliminate market failures and pitfalls.

Governments around the world are actively establishing strategies and initiatives to spread the use of artificial intelligence (AI), for AI is not a mere new technology, but is an innovative technology that brings about extensive changes in industrial and social structures and is a core engine that will lead the 4th Industrial Revolution. The South Korean government has also been paying attention to AI as a technology and tool for innovative growth, but its application to the industries is still rather sluggish. The government has prepared multifarious AI-related policies with the aim of constructing South Korea as an AI powerhouse, but there is no clear strategy on which detailed policies to implement first and which industries to apply AI preferentially. With these limitations of South Korea's AI policies in mind, this paper analyzed the priorities of industries in AI adoption and the priorities of AI-related national policies, using Delphi-AHP method for 30 top-level AI experts in South Korea. The results of analysis show that AI application is urgent and necessary in the fields of medical/healthcare, public and safety, and manufacturing, which seems to reflect the peak of the COVID-19 crisis in the second half of 2020 at the time of the investigation. And it turns out that policies related to AI talent cultivation, data, and R&D investment are important and urgent above all in order for organizations to apply AI. This suggests that strategies are required to focus limited national resources on these industries and policies first.

In these days it is rapidly increasing that multi-user, multi-layered commercial software developments for companies or public institutions. Security services are necessary for most of systems and the access control service is the essential of security services. Current access control methods that are used as access control policies are classified as Discretionary Access Control Mandatory Access Control and Role Based Access Control. However there are some inefficiencies when those methods are applied to current multi-user, multi-layered systems. Therefore it is required that a new access control method that takes complex system resources into account from the side of policy. In this paper extending previous Role Based of 'Behavior' and a basic model of the method. And we simply implement the method on the mobile agent based workflow management system that is a representative example of multi-user. multi-layered softwares and shows implementation results to tap possibilities of real-world application.

Although stochastic programming and feedback control approaches could efficiently mitigate the overdue risks caused by inherent uncertainties in ground conditions, the lack of formal representations of planners' rationales for resource allocation still prevents planners from applying these approaches due to the inability to consider comprehensive resource allocation policies for hard rock tunnel projects. To overcome the limitations, the authors developed an ontology that represents the project duration estimation rationales, considering the impacts of ground conditions, excavation methods, project states, resources (i.e., given equipment fleet), and resource allocation policies (RAPs). This ontology consists of 5 main classes with 22 subclasses. It enables planners to explicitly and comprehensively represent the necessary information to rapidly and consistently estimate the excavation durations during construction. 10 rule sets (i.e., policies) are considered and categorized into two types: non-progress-related and progress-related policies. In order to provide simplified information about the remaining durations of phases for progress-related policies, the ontology also represents encoding principles. The estimation of excavation schedules is carried out based on a hypothetical example considering two types of policies. The estimation results reveal the feasibility, potential for flexibility, and comprehensiveness of the developed ontology. Further research to improve the duration estimation methodology is warranted.
