Digital content industry is growing rapidly because of the property of high-speed networking and greater demand for digital fulltext-image. However, we know the fact that it is many difficulty in production and supply for good quality of content. Hereupon, we suggest digital fulltext-image service framework to protect copyright. More concretely, we propose integrated model and reference model to securely serve digital fulltext-image by recompositing core objects and reconstructing the value-chain structure of digital content industry to framework including the process(from its production (creators or copyrighters) to consumption (users or consumers)). Also, we construct the digital fulltext- image service system based on reference model and reconstruct its interface that occurs between core subjects.

This study develops an Education framework for users who need public open data for workplace etiquette education in a timely manner by mobile application. It facilitates utilizing efficiently Workplace etiquette contents that scattered in various platforms such as blogs, Youtube and web-sites run by private education agencies. Furthermore, it makes Public open data for workplace etiquette through gathering 'metadata', which is a comprehensive source of workplace etiquette. Accordingly, framework changes recognition about necessity of workplace etiquette education positively and suggests method that can promote effective workplace etiquette education. If the system in the study can provide public open data of workplace etiquette education, many young job applicants and workers will have a proper perception on it and sound workplace etiquette culture will be settled in the companies. Public data has been rising as a vital national strategic asset these days. Hopefully the public data will pave a way to discover the blue ocean in the market and open up a new type of businesses.

This study proposed a structural and semantic framework for the characterization of events and segments in Web videos that permits content-based searches and dynamic video summarization. Although MPEG-7 supports multimedia structural and semantic descriptions, it is not currently suitable for describing multimedia content on the Web. Thus, the proposed metadata framework that was designed considering Web environments provides a thorough yet simple way to describe Web video contents. Precisely, the metadata framework was constructed on the basis of Chatman's narrative theory, three multimedia metadata formats (PBCore, MPEG-7, and TV-Anytime), and social metadata. It consists of event information, eventGroup information, segment information, and video (program) information. This study also discusses how to automatically extract metadata elements including structural and semantic metadata elements from Web videos.

A sample procedure has been described to room temperature synthesis, mesoporous aluminosilicate materials with strong surface acidity by using a cationic surfactnat cetyltrimethylammonium bromide(CTABr) as the template agent. All samples were charecterized by X-ray diffraction(XRD) and nitrogen adsorption. The crystallinity and surface area of MCM-41 type aluminosilicats decrease with decreasing of Si/Al ratio. The influence of the aluminum contents of MCM-41 on the coordination of Al and on the acidity is studied by $^{27}Al$ MAS NMR and temperature programmed desorption of ammonia(TPD). It was shown that the incorporation of Al atoms into the framework causes increasing of acid site surface. And then Al atoms in the framework were incorporated tetrahedrally in structure, which gave a rise to cationic sites in the framework.

Purpose: The study aims to delineate Shariah Governance Framework (SGF) by applying the components of New Institutional Theory (NIT) to provide an understanding of how Islamic banks theoretically influence Shariah Governance (SG) practice, structure, and process. Design/methodology/approach: As it is a conceptual paper, this paper has prepared based on an analytical approach to show how such institutions could provide a more effective system concerning the contents, procedures, and practices for the multiple users in the SG process of Islamic banks. Findings: The paper critically explores the adoption of NIT to develop SGF with its existing practice, structure, and procedure. Utilizing NIT, a proposed theoretical framework has developed for exploring the SG through its major components, i.e., 'isomorphism' and 'legitimacy'. It is stated that NIT can offer a useful framework by which homogenous structures, comprising guidelines, standards, and practices become recognized and authorized as a satisfactory standard corporate exercise. Thus, the proposed theoretical framework would be beneficial in understanding and exploring the SGF. Conclusion: The application of this SGF could help to justify the key dimensions of NIT with its overall formation, function, and practices that might also help to attain legitimacy.

According to explosion of smart-devices, demands on N-screen services based on cooperation of multiple screens are rapidly increasing. These N-screen services can provide new user-experience (UX) to users. That is, it can provide technical advances to users. On the other hand, it causes new security problems. In this paper, we analyze conventional web-security attacks, and we propose and analyze new security requirements for migration, combination, and separation of web-contents based on N-screen service scenarios. Also, we develop N-screen cooperation service framework in order to ensure user security.

Following the heightened facilitation of information system in the education field, educational institutions encounter frequent information security infringement accidents. However there is insufficient education for persons in charge of information security duties in educational institutions. This study aims to analyze differences of knowledge and skills required for information security professionals in educational institutions by institution type, service area and duty. Based on the results of multidimensional scaling on survey data, this study presents the information security education framework for educational institutions.

In home network environments, the user authentication and authorization associated user's information and usability may be important security issue. The OSGi service platform, a well-known home network gateway already specifies the mechanism of that. The traditional authority method provided OSGi implements simple RBAC(Role Based Access Control) model. This is difficult to support efficient access control. In this paper, we propose the dynamic RBAC model based on OSGi. The proposed method describes the extended framework that manage two roles named as absolute role and relative role, extend existed framework with relative role and propose programming model to enable dynamic access control. Finally, we implement the proposed framework using AspectJ and Java annotation.

This paper proposes a framework for classifying metric-based software quality prediction models, especially case of software criticality, into four types. Models are classified along two vectors: input metric forms and the necessity of past project data. Each type has its own characteristics and its strength and weakness are compared with those of other types using newly defined criteria. Through this qualitative evaluation each organization can choose a proper model to suit its environment. My earlier studies of criticality prediction model implemented specific models in each type and evaluated their prediction performances. In this paper I analyze the experimental results and show that the characteristics of a model type is the another key of successful model selection.

In this paper, we argue that characteristics of ubiquitous business are different from those of e-business or m-business. We have developed a u-business model development framework incorporating the concept of value co-creation experiences, which is a core of the ubiquitous business paradigm. The framework of u-business model development presented in this paper consists of eight steps such as defining of domain, discovery of opportunity nucleus, defining of potential co-creation experience environment, deriving candidates of u-business services, selecting u-business killer services, defining value propositions of u-business killer services, defining u-business killer service offerings, and drawing a resource map of u-business killer services. The proposed u-business model development framework offers useful guidelines for practitioners to develop successful u-business models under a ubiquitous business paradigm.
