In wartime conditions, the communication system of military aircraft is exposed to jamming, and it is necessary to mount communication equipment with high anti-jamming performance in order to perform air operations smoothly even in an environment where jamming attempts are made. In this paper, we check in detail the jamming and anti-jamming technology that can be applied to wireless communication, and the data disclosed on the difference in specifications of the next-generation anti-jamming radio with frequency hopping method and the improvement of anti-jamming performance according to these changes. It was briefly analyzed within the scope. In addition, the points to be considered when designing a new domestic aircraft and the possibility of installing the next-generation anti-jamming communication equipment on the currently operating aircraft were confirmed, and the tactical usefulness of improving the anti-jamming capability of the next-generation anti-jamming communication equipment was confirmed.

Knowledge sharing by collective intelligence, and knowledge production/sharing by outer cooperation is also important for the company. Therefore, it is needed the next generation KMS(Knowledge Management System) designed and built which based on SNS. In my paper, the problems of KMS are analyzed and new KMS's requirements and paradigm changes are examined by analysis of investigation of existing KMS. KMS based on SNS is appropriate for the next generation KMS in consideration of new KMS's requirements, that is, collective intelligence, open innovation, and convergence with IT technology. So a building method of KMS based on SNS is presented by new next generation KMS's architecture, main design and knowledge-talk design.

Broadcasting telecommunication convergence service means a service where broadcasting and telecommunication converge. Recently with the advancement of technology, broadcasting telecommunication convergence service has been evolving to provide multimedia contents through various devices including wired and wireless network environment. Up to now, IPTV and smartphone-based convergence services have been dominant, but more developed and evolved technology and media will appear in the future. In order to derive the next generation broadcasting telecommunication convergence service supporting model, this study derives an evaluation model of broadcasting telecommunication convergence service and presents a case of evaluation of 30 demonstration projects supported by the Korean government from 2010 to 2014. In this study, we derive an evaluation model and evaluate the demonstration projects by reflecting the position of the main stake holders of service such as users, experts, and related organizational institutions, away from the existing simple service evaluation method. Expert questionnaire used AHP (Analytic Hierarchy Process) method, and the evaluation results were divided into upper and lower groups to provide key implications by a gap analysis. From this analysis this study suggests guidelines for next generation broadcasting telecommunication service support projects. The next generation broadcasting convergence service business should be based on open platform type in terms of service type. In terms of service media, it should be centered on open devices such as smart phones and smart TVs. In terms of types of business responsibilities, it should be led by public organizations and it is necessary to increase the fund matching ratio by at least 62% when the private sector participates.

Recently, the direct terrestrial broadcasting reception has been reduced rapidly and not been improved even in digital broadcast environment. The distribution plan of 700MHz frequency band(Ch.52~69) will make the problem worse because the spectrum might be allocated to mobile communication use. In this paper, we investigated the efficient frequency usage for DTV signal reception improvement and next generation broadcasting. The frequency amount required for reception improvement and for next generation broadcasting service is presented. We estimated the beneficial effect when the spectrum(108MHz Frequency Width) is used for SFN transmission technology, UHDTV and Full-HD 3DTV.

There are two important trends in the modern information society, including digital networking and ubiquitous environment. Thus it is strongly required to develop new information storage devices such as high density storages to match the increased data capacity and small size storage devices to be applied to the mobile multimedia electronics. So far, many approaches have been studied for the high density memory, including the holographic memory, super-RENS and near-field recording using solid immersion lens (SIL) or nano-probe for the ODD (Optical Disk Drive) system, and the perpendicular magnetic recording and heat-assisted magnetic recording for the HDD (Hard Disk Drive) system. In addition, new mobile storage devices have been prepared using 0.85" HDD and 30mm ODD systems from a lot of foreign and domestic companies and institutes. In this paper, the recent technology trend for the next generation information storage system is summarized to offer a research motivation and encouragement to new researchers in this field with an emphasis on the technical issues of the increase of data capacity and decrease of device size.

Identity authentication sharing technologies which allow many service providers to share the result of identity authentication of an identity provider receive high attention as alternatives for current problematic identity authentications in the next-generation Internet environment, since they can provide crucial advantages including high usability, cost effectiveness of service providers, and privacy protection. However, in order for the identity authentication sharing technologies to be widely deployed in global Internet scale, the interoperability problem among different identity authentication sharing protocols and the trustworthiness issue among the participating identity providers, service providers, and users should be resolved in advance. This paper firstly analyzes current status of the protocol interoperability issue and existing trust frameworks for identity authentication sharing. And then, based on the result of analysis, this paper proposes a next generation identity authentication sharing architecture for global Internet.

In the current Internet environment, there may exist a number of independently-operating authentication systems even within a single organization, according to the service types and service providing entities. Current silo-style isolated authentication system model has revealed critical problems in the aspects of usability, cost-effectiveness, extensibility and flexibility, and privacy protection. Recently, several next generation authentication systems have been actively developed by leading industrial and standardization institutions. This paper firstly analyzes the problems of current Internet authentication system environments. And then, the underlying idea, operating procedures, and pros and cons of the newly developed next generation authentication systems are analyzed so as to provide the selection guidelines for the new authentication systems and drive further development directions for future Internet authentication systems.
