Interoperability is the most critical issue facing businesses that need to access information from multiple information systems. Our objective in this research is to develop a comprehensive framework and methodology to facilitate semantic interoperability among distributed and heterogeneous information systems. A comprehensive framework for managing various semantic conflicts is proposed. Our proposed framework provides a unified view of the underlying representational and reasoning formalism fo

While e-commerce has proliferated with the growth of the Internet, there have been insufficient research efforts concerning its status in Korea. The United States, in contrast, has made significant efforts in making empirical research on the consumer's adoption of e-commerce. This paper validates the e-Commerce Adoption Model (e- CAM) on the two countries. E-CAM integrates the technology acceptance model with the theories of perceived risk to explain the e-commerce adoption. The study findings n

Drones cooperate with each other by transmitting and receiving packets. Therefore, it is important to conjecture the packet transmission rates within the network. However, the conventional methods are not suitable to describe the transmission patterns with satisfactory computing speed and accuracy. In this paper, we demonstrated that machine learning can successfully predict the transmission patterns in drone network. The packet transmission rates of a communication network with twenty drones we

E-commerce is increasingly competitive and there is a constant need for new approaches and technology to facilitate exchange. Emerging techniques include the use of artificial intelligence (AI). One AI tool that has sparked interest in e-commerce is the automated negotiation agent (negotiation-agent). This study examines such agents, and proposes an offer strategy model of integrative negotiation for a negotiation-agent with a focus on negotiation agent-to-human interaction. More specifically, a

A clearly-defined and well-structured methodology can reduce ontology development time and increase the possibility of the project success. However, there exists no mature knowledge engineering methodology for ontology developments. Nevertheless, METHONTOLOGY, known as one of the best methodologies, has been adopted in several ontology developments due to its domain-independent characteristics. In this paper, we develop the Graduation Screen Ontology (GSO) based on the guidelines suggested by ME

A new voice activity detector for noisy environments is proposed. In conventional algorithms, the endpoint of speech is found by applying an edge detection filter that finds the abrupt changing point in a feature domain. However, since the frame energy feature is unstable in noisy environments, it is difficult to accurately find the endpoint of speech. Therefore, a novel feature extraction algorithm based on the double-combined Fourier transform and envelope line fitting is proposed. It is combi

The objective of this research is to develop a formal semantic model, theoretical framework and methodology to facilitate interoperability among distributed and heterogeneous geographic database systems (GDSs). A set of prototype data management tools is being implemented to provide proof of concept for this work. Finally, a case study is being employed to evaluate the methodology and prototype tools which can provide further understanding of the interaction between human beings and computer-ass

본 사례는 국내 미디어 엔터테인먼트 산업의 성장과정을 사례연구를 통해 분석하였다. 국내영화산업은 지난 수년간 급속한 성장세를 보여 왔다. 그러나 소수 기업 중심의 과점화, 한정된 시장에서의 경쟁격화 및 국내시장의 포화로 최근 전반적인 수익률은 점점 낮아지고 있는 상태다. 사례기업인 CJ 엔터테인먼트는 국내영화시장의 독보적인 1위 업체로서 계열사 간․기업 내 가치사슬의 수직통합 시너지를 잘 활용한 대표적인 사례로 손꼽힌다. 그러나 최근 국내시장의 위협과 해외시장의 진출 이슈 등 새로운 전략적 방향 설정이 필요한 때이기도 하다. 본 사례는 여타 산업과 다른 영화산업만의 고유한 특성을 분석하는 것으로 시작한다. 이후, CJ 엔터테인먼트의 설립 이후 지난 10년을 중심으로 어떻게 성공적으로 수직통합을 이루었는지 고찰하였다. 마지막으로, 향후 지속적인 성장을 위한 전략적 이슈들을 살펴봄으로써 한국 미디어 엔터테인먼트 기업들이 처한 국내외 경쟁환경에 대한 시사점을 제공하였다.

The degree of weathering, a key parameter for evaluating rock mass strength, has traditionally been assessed based on visual inspection by engineers. In an effort to reduce the human bias associated with this approach, a study was conducted to investigate the potential for using spectral imaging to quantify weathering. This entailed developing a portable, rapid method for narrow-band multispectral (NBMS) remote sensing using a spectral index classification algorithm, applying this algorithm to d

Kakao is a fast growing software company focused on providing innovative smartphone applications. The company is rooted in the Korean mobile communication market where customer demands for high speed connectivity have been growing sharply. Kakao maintains the top position in the category of mobile communication utility tool for the last three years and competes successfully with other new comers. However, the company faces tremendous external threat from traditional smartphone carriers, SK Telec

Abstract This paper aims to develop a coherent analytical tool to explain the dynamics of Sino-Japanese pluralized leadership. Highlighting the constructivist concept of critical strategic practice, it argues that the nature of pluralized leadership is not fixed by existing social structures, but rather can be dynamically changed by potential leaders through critical reflection and actions to transform identities. It then suggests three possible types of pluralized leadership: collective leaders
