Two paradigms characterize much of the research in Information Systems discipline: behavioral science and design science. The behavioral-science paradigm seeks to develop verify theories that explain or predict human organizational behavior. design-science extend boundaries capabilities by creating new innovative artifacts. Both are foundational IS discipline, positioned as it is at confluence people, organizations, technology. Our objective describe performance via a concise conceptual...
Interoperability is the most critical issue facing businesses that need to access information from multiple systems. Our objective in this research develop a comprehensive framework and methodology facilitate semantic interoperability among distributed heterogeneous A for managing various conflicts proposed. proposed provides unified view of underlying representational reasoning formalism mediation process. This then used as basis automating detection resolution sources. We define several...
AbstractAbstractWhile e-commerce has proliferated with the growth of Internet, there have been insufficient research efforts concerning its status in Korea. The United States, contrast, made significant making empirical on consumer's adoption e-commerce. This paper validates e-Commerce Adoption Model (e- CAM) two countries. E-CAM integrates technology acceptance model theories perceived risk to explain adoption. study findings not only provide interim support for generalizability e-CAM, but...
Establishing semantic interoperability among heterogeneous information sources has been a critical issue in the database community for past two decades. Despite importance, current approaches to of databases have not sufficiently effective. We propose common ontology called conflict resolution (SCROL) that addresses inherent difficulties conventional approaches, i.e., federated schema and domain approaches. SCROL provides systematic method automatically detecting resolving various conflicts...
Drones cooperate with each other by transmitting and receiving packets. Therefore, it is important to conjecture the packet transmission rates within network. However, conventional methods are not suitable describe patterns satisfactory computing speed accuracy. In this paper, we demonstrated that machine learning can successfully predict in drone The of a communication network twenty drones were simulated, which results used train linear regression Support Vector Machine Quadratic Kernel...
Chronic injury to hepatocytes results in inflammation, steatohepatitis, fibrosis, and nonalcoholic fatty liver disease (NAFLD). The tetraspanin TM4SF5 is implicated fibrosis cancer. We investigate the role of communication between macrophages (MΦs) its possible influence on inflammatory microenvironment that may lead NAFLD. induction differentiated MΦs promotes glucose uptake, glycolysis, sensitivity, leading M1-type MΦ activation. Activated secrete pro-inflammatory interleukin-6 (IL-6),...
E-commerce is increasingly competitive and there a constant need for new approaches technology to facilitate exchange. Emerging techniques include the use of artificial intelligence (AI). One AI tool that has sparked interest in e-commerce automated negotiation agent (negotiation-agent). This study examines such agents, proposes an offer strategy model integrative negotiation-agent with focus on agent-to-human interaction. More specifically, was developed based bargaining model, which...
Axiomatic Theories and Improving the Relevance of Information Systems Research This paper examines fact that a significant number empirical information systems (IS) studies engage in confirmative testing self-evident axiomatic theories without yielding highly relevant knowledge for IS community. The authors conduct both horizontal analysis 72 representative an in-depth vertical 3 well-known (i.e., technology acceptance model, diffusion innovation theory, institutional theory) order to...
This paper develops and empirically tests a model to evaluate manufacturer's strategy which provides customer relationship management (CRM) technology its exclusive retailers. The impact of the on manufacturer-retailer quality is also examined. research objectives are (1) identify test factors that promote active implementation CRM among small retail organizations; (2) determine whether our expanded concept integrates information activities marketing explains performance better; (3)...
A new voice activity detector for noisy environments is proposed. In conventional algorithms, the endpoint of speech found by applying an edge detection filter that finds abrupt changing point in a feature domain. However, since frame energy unstable environments, it difficult to accurately find speech. Therefore, novel extraction algorithm based on double-combined Fourier transform and envelope line fitting It combined with effective endpoints. Effectiveness proposed evaluated compared...
Abstract Reactive oxygen species (ROS) regulate cell fate, although signaling molecules that ROS hormesis remain unclear. Here we show transmembrane 4 L six family member 5 (TM4SF5) in lung epithelial cells induced the alternatively spliced CD44v8-10 variant via an inverse ZEB2/epithelial splicing regulatory proteins (ESRPs) linkage. TM4SF5 formed complexes with cystine/glutamate antiporter system TM4SF5- and CD44v8-10-dependent CD98hc plasma-membrane enrichment. Dynamic binding to required...
A clearly-defined and well-structured methodology can reduce ontology development time increase the possibility of project success. However, there exists no mature knowledge engineering for developments. Nevertheless, METHONTOLOGY, known as one best methodologies, has been adopted in several developments due to its domain-independent characteristics. In this paper, we develop Graduation Screen Ontology (GSO) based on guidelines suggested by METHONTOLOGY analyze life cycle identify issues...
