Internal communication is primarily to provide efficient, mutual flow of information between employees and management staff at all levels in each area of the organization. In order to present internal communication tools and evaluate their effectiveness a survey study was conducted among the employees of the listed media company Cyfrowy Polsat, one of the two leading private TV groups in Poland. The study involved 136 employees （17% of total employment）. The majority of respondents were male （85%）. All the respondents were 23 to 47 years of age. Almost half were below 24 years of age and 38% represented the age group 25-34 years of age. The majority of respondents declared higher education with master degree and working time exceeding three years. The survey showed that the dominant form of communication is message distribution via electronic channels which confirmed the research assumption that there was a dehumanization of contacts and indirect communication dominated over direct contact. Limited direct contact was also recognized as the major cause of conflicts and disputes. The study was based on the analysis of literature and source materials （reports, statistics, newsletters, and legal acts）. Additionally, the paper provides the presentation of Cyfrowy Polsat＇s position in the Polish media market as well as the strategies and objectives of the company.展开更多

However, in the year 2014, 12 people in the European Union have died every day because of the lack of available organs. Nearly, 70,000 people were waiting for a matching graft. An analysis of donation and transplantation variation across the European member states shows that since many years, Spain occupies a pioneer role, whereas Germany and Austria are lagging behind. From the legal and administrative perspective, Spain and Austria are quite similar with their presumed consent system （opting out）, whereas Germany has an informed consent system （opting in）. Hence, there must be other influencing factors like the way of multilevel communication leading to the following research question： How does multilevel communication influence organ donations in Spain, Germany, and Austria？ On the basis of a cross-country study, it can be shown that strategic communication on the （inter）personal and organizational level supported by the creation of public awareness on the national level is crucial for succeeding in closing the gap between demands and realized organ transplantation.展开更多

This construction is carried out in the course of the organizational existence and it is reflected in the image that it depicts. Those two elements are essential values to be handled by promotional communication through its several channels, means, and products. The aim of the study is to discuss the importance of corporate identity and image in the promotional communication of an organization. Bibliographical research and a case study were both used as methodologies. We have found the need to cultivate a positive image for the consolidation of the future of the organization including the contribution to the economic development of the country.展开更多

These antennas, transparent and flexible, will be easily integrated into various mdia and in particular OLED lighting which could be part of the public lighting network of tomorrow as well as on all display media. The integration of these antennas as close as possible to the end-user is a possible solution to reduce the energy consumption which goes hand in hand with the increase in the data rate. This kind of new antenna, designed to be integrated in organic light-emitting diode (OLED), was modeled from a transparent VeilShieldTM conductive fabric and was placed on a 100% polyester substrate with a thickness of 1.5 mm and a loss tangent of 0.02. We have tested and evaluated the characteristic parameters of our antenna, namely the reflection coefficient, the radiation pattern and the gain, to find out the performance of our proposed design. The performance of the transparent conductive fabric integrated in the 100% polyester substrate is tested for the application of flexible antenna operating at 3.5 GHz with a gain value of 5.38 dB. We have integrated this proposed new antenna with the OLED light source containing four layers of different materials and electrical properties: aluminum cathode layer, polymer layer, indium tin oxide (ITO) anode layer and glass substrate layer. After integration, the resonant frequency shifted to 3.52 GHz with a gain value of 4.61 dB. In addition, we also tested the concave bending on the reflection coefficient of the proposed flexible antenna taking into account the different bending angles. This work demonstrates the possibility of integrating these unconventional materials used for the proposed antenna within the OLED despite weak effects on the resonant frequency and the gain of the proposed antenna after integration.展开更多

The primary basis shows the way to eliminate or remove the problem fields, the so-called non-profit organizations failures such as philanthropic insufficiency, philanthropic paternalism, philanthropic amateurism and philanthropic particularism. These present the final values and provide conclusions of the Analysis of Non-profit Non-governmental Organisations of Zlin Region. The current situation reveals the longstanding problem of non-profit non-governmental organizations, which is the absence of professional marketing staff, and suggests new possibilities for university graduates＂ application on the labour market, thus creating the essential platform for new approaches in designing educational programs. Non-profit organizations should therefore pay increasing attention to addressing both general public and particularly the youth since young people may be their future volunteers, employees, donors and sympathizers.展开更多
