  • The recent years, the cloud-based paradigm of cloud services are developed rapidly, it come with many a new problems. However, the collaboration between a individual with other users is still difficult. Cloud service is considered when users need to take advantage of security and the availability of cloud services. In this paper, we proposed an detection framework to detect an intrusion attack that threaten to cloud-based collaboration services and cloud security. Identify vulnerabilities and prepare for the safety of the collaboration services to create a variety of content in the cloud, it help to prevent the threats.

  • Purpose As non-face-to-face work environments become common due to COVID-19, interest in online collaboration tools that can communicate smoothly without time and space limitations is continuously increasing. Most of the prior studies are about the introduction, use intention, and satisfaction of cloud computing-based collaboration tools, and studies on the effects of collaboration tools on work-life balance and quality of life are somewhat lacking. Therefore, in this study, the characteristics of cloud computing-based collaboration tools were derived, and the effect on job satisfaction during work and job stress outside of working hours was confirmed. Design/methodology/approach This study applied the S-O-R framework and conducted an online survey of office workers who used cloud computing-based collaboration tools for more than three months. Hypotheses were tested using structural equations. Findings As a result of the analysis, among the characteristics of collaboration tools, stability, usefulness, and interoperability had higher job satisfaction as more stimuli were applied. In addition, the higher the job satisfaction during work, the higher the job performance, work-life balance, and quality of life.

  • 클라우드 서비스는 비즈니스 향상을 위해 사용되며, 특히, 고객 관리에서는 고객 서비스 향상을 위한 툴로서 소셜 네트워크를 사용한다. 그러나 대부분의 클라우드 시스템은 시멘틱 구조를 지원하지 않기 때문에 소셜 네트워크 사이트의 중요한 정보는 비즈니스 정책을 위해 처리 및 사용이 어렵다. 본 연구에서는 클라우드 시스템에서 소셜 시멘틱 웹에 기반을 둔 협력 프레임 워크를 제안한다. 제안한 프레임 워크는 클라우드 소비자와 서비스 제공자를 위한 효율적인 협력시스템을 제공하기 위해, 소셜 시멘틱 웹 지원을 위한 요소들로 구성된다. 지식획득모듈은 소셜 에이전트가 수집한 데이터로부터 규칙을 추출하며, 이 규칙들은 협력 및 경영정책에 사용된다. 본 논문은 제안한 시멘틱 모델에서 소셜 네트워크 사이트 데이터의 처리 및 효율적인 협력을 위한 클라우드 서비스 제공자의 가상 그룹핑을 위해 사용될 패턴 추출에 대한 구현 결과를 보여준다.

  • 최근 많은 IT 기업들이 클라우드 서비스 시장에 진입하면서 출시되는 클라우드 서비스의 숫자가 크게 늘어나고 있다. 이러한 이유로 발생하는 클라우드 서비스 선택의 문제들을 해결하고, 기술적인 역량이 부족한 클라우드 서비스 사용자들의 서비스 초기화와 운용을 돕기 위해서 클라우드 서비스 중개업 회사들이 크게 주목받고 있다. 본 연구에서는 원 클라우드 서비스 제공자들과 클라우드 서비스 중개업 회사들 간의 협업을 대표적인 사례들인 국내의 NCloud24와 미국의 RightScale을 통해 보았다. 두 회사의 비즈니스 모델을 비즈니스 모델 캔버스를 사용하여 분석하였으며, 클라우드 서비스 중개업 회사들의 출현을 IaaS(Infrastructure-as-a-Service) 클라우드 서비스 회사들의 언번들링(Unbundling) 과정으로 해석하였다. 그리고 두 사례간의 차이점을 비교하고, 이를 바탕으로 향후 국내 클라우드 서비스 중개업이 나아가야 할 방향에 대하여 조망하였다.

  • Marine equipment makers today face a multitude of challenges including the needs of an internal system for easy management of their business processes and a collaboration system to streamline communications with the parent company, increasing product complexity and heightened requirements for information technology. In this research, a BPM-ERP system called Biz $Tower^{(R)}$ was implemented based on cloud computing for especially, small and medium marine equipment makers to standardize and visualize the entire business process from order placement to release. This system also provides their parent company with visibility into the status of orders and user can easily access the system on the web at a low price through cloud computing service. Thus far, this paper demonstrates the applicability of Biz $Tower^{(R)}$ to improve management visibility, process performance, and collaboration with the parent company for small and medium marine equipment makers.

  • As the fast development of information technology (IT), abundant attractive alternatives have showed up and challenged to the traditional information technology (IT). Cloud services, the hottest representative among these alternatives, has attracted the attention from all walks of life. Considering the diversity of cloud services, this study attempts to find out the important factors affected on individual's switching intention from incumbent IT to cloud services mainly based on two-factor theory (switching enablers and switching inhibitors) and explore the direct influences of these factors on individual's switching intention. According to our findings, individual's switching intention to cloud services is not only positively influenced by switching enablers but also negatively influenced by switching inhibitors. All the switching enablers in this study (perceived omnipresence, perceived collaboration support and perceived compatibility of cloud services) have positively significant influences on individual's switching intention as well as the switching inhibitors (usage habit of incumbent IT and perceived risk of cloud services) have negatively significant influences on individual's switching intention. It's noteworthy that satisfaction of incumbent IT has insignificant influence on individual's switching intention in this study. Moreover, as we expected, both social influence and personal innovativeness have significant influences on the generation of individual's switching intention.

  • This letter presents a model for a dynamic collaboration (DC) platform among cloud providers (CPs) that prevents adverse business impacts, cloud vendor lock-in and violation of service level agreements with consumers, and also offers collaborative cloud services to consumers. We consider two major challenges. The first challenge is to find an appropriate market model in order to enable the DC platform. The second is to select suitable collaborative partners to provide services. We propose a novel combinatorial auction-based cloud market model that enables a DC platform among CPs. We also propose a new promising multi-objective optimization model to quantitatively evaluate the partners. Simulation experiments were conducted to verify both of the proposed models.

  • The challenges facing manufacturing companies today span across the industry, independent of company size or product. Especially, big manufacturers must overcome these challenges, and information technology (IT) collaboration with small and medium enterprises (SMEs) will play a major role in this effort. In this research, the strategy and way to promote IT collaboration between SMEs and large firms in heavy industries are proposed. A pre-consultation was performed to derive the strategy and way for the collaboration, and an IT collaboration system was developed reflection the results of pre-consultation. The IT collaboration system consists of two parts. One is ERP based on BPM for SMEs to standardize and visualize the entire business process from order placement to release. This system also provides their parent company with visibility into the status of orders and user can easily access the system on the web at a low price through cloud computing service. The other is interface part for data changes between large firms and SMEs. Thus far, this paper demonstrates the importance of strategy for the collaboration, and the applicability of IT collaboration system to elevate the speed and efficiency of business.
