The purpose of this paper is to identify security technologies that are essential in making home network systems secure and to describe specialized security mechanisms for the home network and the relationships among them.

The research model is designed to support three functions: authentication, authorization, and security policy. Authentication is tested in several methodologies such as id/pw, certificate, or bio; authorization is tested using RBAC methodologies; and security policy is specified using newly‐designed script language, such as xHDL.

The findings for “authentication” suggest that home network users can access services conveniently and securely. In addition, the findings for “security policy” suggest that security policy for home network requires specialized rather than general specification.

The paper identifies three security functions essential for home network: authentication that supports most existing authentication mechanisms, so as to maximize user accessibility; authorization that is middleware‐independent and beyond the physical transport layer; and security policy optimized for the home network environment.

The paper focuses on an implementation‐based security model for the home network. Though interest and research in home network security are increasing, only limited authentication applications have been adopted in real deployment up to now. This paper introduces an integrated security model and emphasizes safety and convenience so as to promote reliability in home network services.

Social networking services (SNS) sites such as Facebook and Twitter have increasingly established themselves as a new paradigm of communication. Due to the rapid popularization of mobile devices, mobile SNS are creating a particularly significant change in the way in which information is distributed. The purpose of this paper is to propose a mobile SNS system tailored for archival information services (AIS) in South Korea.

In order to find an appropriate service structure for the proposed AIS system, the authors conduct a case study of the existing mobile SNS sites. In addition to this, the authors investigate how mobile SNS are currently used in libraries and archives. Based on the results, they propose a mobile SNS structure suitable for the AIS system, for which a user interface and database is designed and implemented.

The proposed system can leverage mobile SNS to expand the accessibility of AIS and encourage active participation and cooperation from users.

The proposed system can improve the security vulnerabilities inherent in Facebook and Twitter; further, it can induce active user participation through two-way communication channels with users and also produce high-quality information by providing a communication space between the archiving experts.

Pyrus Pyrifolia (Sand Pear) is one of the most underused pear variety despite its nutraceutical potential. Therefore, this paper aims to explore the Pyrus Pyrifolia in term of origin, distribution and classification, nutritional and bioactive potential, therapeutic potential and valorization along with future prospectus.

A wide variety of publications (88) were identified through electronic databases (Science direct, PubMed, SciELO, Google scholar, Link springer and Research gate) under the umbrella of different keywords such as bioactive compounds, health benefits, nutrition, sand pear, Pyrus and Pyrus pyrifolia.

Pyrus Pyrifolia (Sand Pear) is abundant in nutritional and bioactive compounds such as phenolic acids, flavonoids, terpenoids, vitamins and minerals. It exhibits therapeutic potential as being an antioxidant, anti-obesity, anti-diabetic, anti-inflammatory and anti-cancer agent. However, P. pyrifolia is not much explored by food researchers and industrialists, hence remaining underused. A few attempts have been made toward the use of P. pyrifolia for jam, jelly, candy and wine preparation. However, more research is required for the commercial processing of P. pyrifolia and to enhance its availability outside its growing area.

In this paper, nutritional and bioactive compounds of P. pyrifolia are discussed that provide knowledge to the researchers for its use as a functional ingredient.
