In the age of rapid development of communication technologies the educational process in the area of communication networks has the enormous significance. In this process the large number of skilled network professionals such as: software developers, system administrators, security engineers, etc., has to be trained. One of the most important elements of this process is existence of suitable educational environments. Nowadays the virtual network laboratories emerged as highly efficient environments for training network professionals. These environments are based on virtualization technology and provide working conditions in the emulated environments with the high level of reality. This paper deals with the important issues to be concerned in process of design and implementation of these laboratories. The structure of this laboratories and its configuration strongly depends on purpose and needs of the educational process itself, as well as of the current technology trends in the world. In this paper is presented the approach in defining the structure of virtual network laboratory and its design. This approach is based on research of current market trends, the dominant platforms and technologies used today, and on world trends in high education strategy and planning, especially in the area of networking and communication and related subjects as well. Analyzed data is used for design of the high efficiency virtual network laboratory able to provide the desired learning outcome. The architecture and structure of implemented laboratory is also described.

Taiwan's government has promoted investment in an offshore wind power farm, and local fishermen have protested. A social impact assessment (SIA) has examined the impact of the proposed offshore wind power farm on all stakeholders. The main objective of the present study was to develop an indicator system for measuring the social sustainability of offshore wind power farms; this study also reports on the particular case of Taiwan's offshore wind power project. This study began by defining 35 social sustainability indicators and selecting 23 representative indicators by using rough set theory. Subsequently, 14 key indicators were constructed using the social construction of technology (SCOT) method. Finally, we developed a social impact index for evaluating the social sustainability of offshore wind power farms by using the analytic network process and Dempster-Shafer theory. Our social impact index yields a total score of 0.149 for Taiwan's pilot offshore wind power project; this result indicates that the pilot project is socially sustainable. A substantial contradiction exists between the fishermen's protest and the results of the social impact assessment. The findings can assist the government in building a coordination platform for the investors and the fishermen. Government regulation is necessary to set boundaries for fishing areas that protect both the fishermen's and investors' rights.

Abstract:Qualitative research methods have gained attention in education research because they enable investigation of several people-related issues that cannot be researched with the use of quantitative methods. Qualitative data are mostly collected as unstructured text by using variety of techniques. Collected data are grounded in research participants' experiences and everyday practice. Application of well-established methods for data collection and analysis ensures that research findings accurately present the investigated phenomenon. In this paper, are presented the excerpts from two studies that use different techniques in collecting qualitative field data. The studies are related to university level education within the field of information technology. Both authors in the course of their research used the principles of grounded theory to analyze the qualitative data. According to the experience that they have gained in this process, they reflect on some problems encountered during the process of collecting data, discuss the pros and cons of their choice and exemplify the most fruitful data that emerged in their studies. The paper concludes with some suggestions for further research in the field.
