No full textCategorizing Security for Security Management and Information Resource Management
No full textThere are various definitions and dimensions of security, and there is no comprehensive taxonomy of security. The existing classifications of security are fragmented, scattered, and divergent, binging challenges in the management of security and the management of information resources about security. This research aims to study the problems of security categorization in existing knowledge organization systems, and to develop a comprehensive taxonomy of security. Through thematic analysis of the literature about security, we found that, despite the various definitions and dimensions of security, there is a common feature of security. That is, security is expressed in this pattern: subject wants to protect object against source of insecurity using certain methods. Through facet analysis, we identified four facets of security – subject/scope of security, object of protection, source of insecurity, and method of security. By nesting the four facets to reveal the content of comprehensive security terms (such as national security, human security), we can build comprehensive taxonomies of security for various user groups. This paper develops a tetra-facet model of security, and demonstrates the application of thematic analysis and facet analysis to solve a complex problem of security categorization
An Edible and Quick-Dissolving Film from Cassia Gum and Ethyl Cellulose with Improved Moisture Barrier for Packaging Dried Vegetables
No full textA quick-dissolving edible film was made from cassia gum (CG) incorporated with ethyl cellulose (EC). Mechanical results show that addition of 5% EC based on CG gave rise to the highest tensile strength (TS) of the composite film. Scanning electron microscopy revealed that excess addition of EC slightly decreased the homogeneousness of films. Fourier transform infrared spectroscopy showed that the compatibility between CG and EC was good and the incorporation of EC changed the original interaction of molecules by forming hydrogen bonds with CG. Although film light transmittance decreased, it is transparent enough for packaging. The film water vapour barrier property improved dramatically by blending CG and EC, although they showed dissolution rates over 80% in boiling water after 5 min. The dried carrot cube packaged by CG-EC films showed lower mass growth rates in 53% RH. Therefore, the film presents a potential application in packaging of dried vegetables in convenience foods
