Background: Organizational ostracism is defined as a violation of norms that we are suggested to acknowledge at the workplace. It results in the exclusion of one person or multiple persons, and causes damage to our innate need to belong. This kind of behaviorism can be engaged through a hierarchical or nonhierarchical relationship. Three elements interact in the framework of organizational ostracism: the actor, the target, and the institution. Our aim was to describe the different factors interacting with every element in order to produce recommendations targeting to prevent the occurrence of such behaviorism in an institution and to help targets of such a violence in order to handle this situation and go forward. As psychological impact of ostracism has frequently been studied in the literature, we focused on its impact on professional tasks. Methods: We performed a questionnaire-based study about organizational ostracism. This questionnaire was established through an online platform (https://www.sondageonline.com) and made available through the following link: https://goo.gl/forms/KrkVXe3bMEc79cau2. A keyword was sent to all participants. We created a 23-interrogation questionnaire with open and short questions. Nonwritten consent was obtained from all participants. Results: The actor of ostracism engaged in ostracism, in most of the cases, with other persons without a real purpose. The actor of ostracism had an antecedent of problematic relationship at work in 82.9% of the cases. Of the participants, 58.5% were of the view that ostracism aimed to cause hurt and isolate them. Professional isolation was observed in 58.5% of the cases; 51.2% of the participants tried to improve their work potential and explained their reaction by an intrinsic motivation. The organization atmosphere was judged to be bad in most of the cases. Conclusion: Our study showed that ostracism was mainly observed in public practice.

Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

In this paper, we divided domestic and foreign digital cultural activation policies into four types. We also described projects of each policy and analyzed the limitations of the policy. Finally, we suggested solutions to overcome these limitations. Changes in daily life caused by the recent development of 5G network technology, augmented reality, and virtual reality technology have brought many changes in the way of preservation and utilization of cultural heritage. In particular, digital technology is used for digitization of cultural heritage, storing, and managing digital data, digitally restoring cultural heritage, and enabling time, space, multi-sensory experiences. For this purpose, new policies was required to utilize this. This study divides domestic and international digital heritage policies into digital infrastructure construction, sharing and communication platform construction, public relations, and demonstration contents production support policies. This study is meaningful in classifying the fields of digital heritage policy and introducing digital heritage policy trends. It is also meaningful to suggest ways to improve digital heritage policies through analysis of domestic and foreign cases.

The purpose of this study is to suggest the development of interactive services and technologies in the media industry. Through the analysis of domestic two-way broadcasting contents service, this study analyzed platform and services type according to service type of terrestrial broadcasting, SO operator and Telco. Also, by identifying the characteristics of interactive programs(open, interactive, personalized, stereoscopic), this study propose important convergence possibilities of the future providers and development plans through supporting technologies and services for each characteristic. In the case of terrestrial broadcasters, ARS, web sites and mobile apps were mostly provided in both directions, and SO and satellite broadcasting operators were found to provide diversity in interactive service operation using data domain. In the case of IPTV companies, most of them provide interactive services with additional video or information service through adjustment button or app, and cable TV operators had more adjustment data broadcasting than exclusive use data broadcasts. Therefore, domestic interactive broadcasting service type needs convergence type of revenue model needs and needs to be converted into new competitive interactive broadcasting program service environment.

The relevance of intelligence involves the definition of such communication systems of PR-management and branding of media channels with the use of social networks, which are already implemented in practice by modern representatives of professional PR product. The purpose of the investigation is to determine the system of implementation of technologies of PR-management and branding of media channels with the use of social networks based on a survey of PR and brand of different media channels on the basis of a survey of brand managers and PR. 980 respondents from Ukraine took part in the survey. The survey was conducted on the Google-forms platform. The results outline a list of the most popular social networks and messengers for the implementation of PR management and branding technologies, including Facebook, Twitter, Google, LinkedIn, Tumblr; Telegram, WhatsApp, Viber, Skype. It is determined that the criteria of branding analysis are informativeness, centralization/distribution, content, feedback intensity. Identified 2 prospects for the development of branding in an interactive media environment (creation of a presentation system; integration of websites of social media and companies in universal centers). The criteria of general importance of the factors influencing the behavioral intention of consumers to use social media channels are presented (satisfaction, accessibility, perceived usefulness, trust, ease of use, attitude, social influence, self-efficacy). The meaning of the content of social media channels (public, informational and communication) is indicated. The practical significance of the study was to present the links between the criteria, development prospects and the values of branding factors.

Because of its physical characteristics, earthquake has a great impact on a wide area in a short time, so it needs a resilience based seismic countermeasures to restore the community function. For this reason, in this study, the seismic damages of urban buildings were assessed stochastically by virtual earthquakes using public data information and disaster management program(Ergo-EQ). A geographical map reflecting geological characteristics of the target area was created with the buildings and topographic data in Dalseo-gu, Daegu City. In addition, an integrated database including building characteristics was modified to be linked with the Ergo-EQ program. The seismic damages for the buildings were evaluated through the exceedance probability of four different damage levels. From the damage results, it can be identified not only the seismic damage of each building, but also the major factors affecting earthquake damage.

The introduction of video conferencing service, the core service of smart work is activated mostly at the public organizations and large companies according to the government's recent strategy to promote the introduction of smart work. However, as a variety of products of major foreign and small domestic companies have installed in case of the domestic introduction of video conferencing, it is very urgent and important to secure interoperability among newly installed equipments as well as installed equipments. In addition, as the requirement of market situation has changed from securing interoperability only among the video conferencing systems of the same company to doing the interoperability among the various formed products of a plurality of companies, it is required to develop the standard to enable inter-working. Therefore, in this paper we propose the standardization directions in securing the interoperability of platform specifications through the standards development for interoperability profile among video conferencing systems and services.

A design of an elliptic curve cryptography (ECC) processor that supports both pseudo-random curves and Koblitz curves over $GF(2^m)$ defined by the NIST standard is described in this paper. A finite field arithmetic circuit based on a word-based Montgomery multiplier was designed to support five key lengths using a datapath of fixed size, as well as to achieve a lightweight hardware implementation. In addition, Lopez-Dahab's coordinate system was adopted to remove the finite field division operation. The ECC processor was implemented in the FPGA verification platform and the hardware operation was verified by Elliptic Curve Diffie-Hellman (ECDH) key exchange protocol operation. The ECC processor that was synthesized with a 180-nm CMOS cell library occupied 10,674 gate equivalents (GEs) and a dual-port RAM of 9 kbits, and the maximum clock frequency was estimated at 154 MHz. The scalar multiplication operation over the 223-bit pseudo-random elliptic curve takes 1,112,221 clock cycles and has a throughput of 32.3 kbps.

Interactive documentary refers to a new style of documentary that is created and accepted through active interaction. It is attracting attention as a platform that forms a public sphere and mediates audiences to participate in social change. However, the possibilities was not systematically explored, and there was insufficient consideration on how to realize them. In this paper, discussions on the political aesthetics of Walter Benjamin are examined, and the media characteristics of interactive documentary are analyzed through text mining. Then, by connecting the two to each other, we draw a map of the political and aesthetic possibilities, and based on the map, we analyze the actual works. This study has the value of establishing a theoretical framework for the possibilities of interactive documentaries. In the follow-up study, we will consider the practical strategy of interactive documentary as a transmedia activism and develop a practical analysis and planning methodology.
