The scanning vibrating electrode technique was employed to monitor the in situ localised electrochemical activity on aluminium alloy 2024-T3 at the free corrosion potential in aggressive NaCl solutions with and without corrosion inhibitors 2-mercaptobenzimidazole (MBI) and octylphosphonic acid (OPA). MBI is a very effective inhibitor against pitting corrosion, even in a chloride environment without the reservoir of MBI. In contrast, localised corrosion was observed at several points at the early stage of immersion of AA2024 in NaCl solution containing OPA. Ex situ energy-dispersive X-ray spectroscopy analysis of the Al_2CuMg particle at the cross-section revealed that MBI does not entirely prevent its dissolution but reduces the dissolution rate and the rate of oxygen reduction by forming an insoluble complex compound Cu–MBI on the partially dealloyed AlCu-based particles, i.e., on the porous copper remnants. The MBI’s action is an efficient option for mitigating the corrosion of Cu-based aluminium alloys.
The article analyzes the role of higher education institutions in developing and improving sustainable competencies, particularly emphasizing the presence of sustainable development goals in the bachelor programs of the Faculty of Political Sciences at the University of Sarajevo. The authors have analyzed the compatibility of learning outcomes of bachelor programs with sustainable competencies. This analysis showed that the learning outcomes of the six programs were partially aligned with sustainable competencies. In addition to the analysis of learning outcomes, authors have analyzed the presence of the sustainable development goals in thematic units, and they have found that out of 143 courses, 74 courses contain thematic units related to sustainable development goals. Based on this analysis, it was determined that all sustainable development goals were covered within 74 courses. The research results were used to prepare recommendations for improving bachelor programs.
According to the WHO data from May 2022, the COVID-19 pandemic caused a global health crisis with more than 515 million infected and over 6 million deaths as a result of COVID-19. Just over 11.5 billion vaccines have been administered to prevent severe disease and mortality from SARS-CoV-2 infection. In addition to that, COVID-19 had dramatic effects on all aspects of the society, including the fundamental factors of its functionality - education and health, preventing the continuity of its "normal" functioning. Crisis management measures have had more or less successful results in different countries, but no health system has been able to fully address the effects of the pandemic on the health of the population. The course of the epidemiological crisis and the success of the implementation of global vaccination measures are directly related to the adaptability of individual societies / its capacity to change and adapt. in analyzing the situation and predicting the course of the pandemic. Analytical ability, reliability of prediction, but also flexibility of legislative and executive power, are the most prominent parameters of a society that is ready for the unpredictability of the course and outcome of the global social crisis caused by the pandemic. In the local concept of the development of higher education until 2030, it is necessary to include the mentioned, global principles of adaptability to crises in all spheres of social activity. One of the most powerful instruments of social understanding is education, and here lies the potential of society to adapt and change in order to adapt to the challenges of the modern world through the acceptance of values and norms based on knowledge.
In order to raise and harmonize the quality standards of pharmaceutical studies at the national level of Bosnia and Herzegovina and thus get closer to the implementation and quality assurance of study programs of EU countries, a team of professors from the University of Sarajevo-Faculty of Pharmacy prepared and was awarded the Erasmus+ project IQPharm. IQPharm (Innovating quality assessment tools for pharmacy studies in Bosnia and Herzegovina) aims at capacity building of quality management, and aims to introduce new tools for quality improvement, digitization and modernization of pharmacy studies at public universities in Bosnia and Herzegovina, including strengthening semi-structured experiential education in line with EU standards and higher education regulations for regulated professions. The introduction of new tools for the assessment of the quality of study programs (KREF) enables the development of evidence-based recommendations for change, modification and innovation of existing methods of knowledge transfer, didactic approaches and curricula. The introduction of a new system of proficiency testing through experiential education (OSCE) sets equal standards at the national level for the learning outcomes of graduate pharmacists. The development of E-platform ensures the digitization and modernization of experiential education management. Experiential education at the level of Bosnia and Herzegovina will be significantly improved through the introduction of the E-platform, by raising the standards of the practice itself and facilitating its implementation by student services, students and their mentors. A special part of this project is the development of free modules, which are extracurricular subjects intended to enrich the knowledge of students and graduates of pharmacy, They should track the labor market trends, and thus make higher education more agile and attractive.
The quality management system at the University of Sarajevo is guided by the following principles: promotion of constant improvement of the quality of the study programmes and the application of the best educational approaches and practices. The Bologna process gives special importance to outcome based education (OBE), so learning outcomes are established as a new measure of institutional excellence, shifting a change in focus from "What should student do to successfully complete her/his studies?" to "What competences student acquired during her/his studies?" or more precisely "What can student do after finishing her/his studies?". In this paper, after basic information about outcome based education and the importance of this approach with the implementation of the Bologna process in the European Higher Education Area (EHEA), an overview of the approach to quality assurance and to study programmes improvements based on learning outcomes is given. Focus on learning outcomes enables the fundamental change of the focus from the teacher to the student, which is one of the foundations of the Standards and Guidelines for Quality Assurance in the EHEA (ESG).
This paper presents the electronic publishing development at the University of Sarajevo through two projects, the development of the publishing portal of the Faculty of Philosophy and the implementation of the Open Journal System for the Social Issues Journal Pregled, published by the University of Sarajevo. As a technical solution, the electronic publishing portal of the Faculty of Philosophy combines Open Monograph Press and Open Journal System. Till now, three journals and more than sixty books published by the Faculty are available through this portal. In the previous period we completed the first phase of archiving the magazine Pregled with 1000 articles, accompanied by relevant metadata. This paper aims to present how librarians can contribute to the development of electronic publishing and open access. In the paper, we will also present plans for the next period that includes the creation of the Scientific Serial Publications Register of the University of Sarajevo.
Awareness about the importance of marketing of higher education institutions has been steadily growing amongst decision makers on international level. That trend is particularly noticeable in case of adult education programs, which need continual promotion since it is a type of non-formal education. In Bosnia and Herzegovina private universities and private providers of non-formal education programs have been promoting adult education for some time now. At the same time public universities, mainly influenced by the marketing myopia phenomenon, use promotional activities only sporadically. Therefore, for the purpose of improving promotion of adult education programs in public universities, a qualitative exploratory study has been conducted. The aim was to investigate attitudes and opinions of adults about promotion activities for adult education programs. Data was collected through focus groups from representatives of four generations: Baby Boomers, Generation X, Y and Z. Research results show that different generations have different needs and expectations when it comes to adult education programs. A generally positive attitude towards adult education programs has emerged. Values have been identified which could be communicated through promotion activities. Based on research results several recommendations are given for improvement of adult education promotion. Research results presented in this article directly contribute to achieving UNESCO's Education for Sustainable Development 2030 agenda (priorities 1, 2, 3 and 5), contributing further indirectly to achieving Sustainable Development Goals 4, 8 and 10.
The aim of this paper is to present the Information System on Research Activity in Bosnia and Herzegovina - E-CRIS.BH, and the total number of registered researchers, research organizations, departments and projects, but also the number of bibliographic records to which the typology of documents/works has been assigned within the mutual COBISS.BH database. E-CRIS.BH is an information system that represents an electronic database of researchers, research organizations, research departments and research projects. It is an information system on research activities in Bosnia and Herzegovina, which originated from the Register of Scientific Institutions, Scientific Staff, Scientific and Research Projects and Infrastructure Investments in the Federation of Bosnia and Herzegovina and the Register of Scientific Institutions, Scientific Staff, Scientific and Research Projects and Infrastructure Investments in Canton of Sarajevo. The Register of the Federation of Bosnia and Herzegovina is conceived as an umbrella system and the registers of the canton as its subsystems. The project was implemented by the Academy of Sciences and Arts of Bosnia and Herzegovina. The connection of E-CRIS.BH with the bibliographic database of COBISS.BH provides insight into the bibliographies of researchers, which are an integral part of every scientific work, a condition for synthesizing knowledge and data that lead to the required scientific results. The COBISS users have the opportunity to record researchers, research organizations, departments and projects necessary for the creation of a bibliography of researchers and organizations within their national library information systems in the COBISS.Net network (regional network). The results show that 2.230 researchers and 86 organizations have been registered so far in E-CRIS.BH. A total of 73.657 bibliographic records have been created so far within the COBISS.BH common database, which a typology of documents/works has been assigned to. In the first group – articles and other components – a typology was determined for 21.122 bibliographic records. In the second group – monographs and other completed works - a typology was determined for 52.372 bibliographic records. In the third group – performed works - (events) – a typology was determined for 163 bibliographic records.
The subject of the analysis are the practices and effects of changed direct, interpersonal communication on teachers – students reality in the form of online consultations, in new communication technologies mediated by patterns. The text analyzes the transformation of traditional, academic communication practices in teaching processes conditioned not primarily by technological but existential reasons, starting from the hypothesis that the effectiveness of consultative, communication forms cannot be achieved exclusively through mediated forms, the absence of interpersonal, social interaction. The purpose of the analysis was related both to recording the real effects of mediated communication patterns of online consultations and to analyzing indicators of improvement and development forms of online teaching. On the selected sample of students and teachers of the Department of Communication and Journalism Studies, Faculty of Political Science, University of Sarajevo, primarily, study-oriented and interested in the field of studying and researching communication processes, the surveys aims to analyze conditionally mediated communication from the aspect of communicators, participants in the communication as well as from the aspect of the content and mediator of the communication process and its effects in comparison with established, traditional academic practices. The results of the examination of attitudes indicate that the mediated patterns of consultative forms optimized the material, technical dimension of transmission and reception, but reduced the qualitative, content aspect of the message in terms of its understanding and the inclusion of sensory inputs in the communication process. Untimeliness in responding to inquiries, different denotative and connotative forms of understanding the message, and the absence of metacommunication are just some of the recorded indicators of the absence of basic conditions for effective communication in forms of mediated consultation.
Academic mobility is a valuable and indispensable mechanism in each country's higher education quality assurance system. It also contributes to building and improving the capacities of individual universities because it enables the introduction of positive and proven teaching practices, modern teaching and research methods, and operational and administrative processes. The added value of mobility is the establishment of personal contacts and professional networking of teaching, scientific, artistic and non-teaching staff of the University of Sarajevo (from now on: "UNSA"), which has a long-term effect on the development of teaching, scientific and technological capacity. Studying through mobility gets an international note - students understand their work in a global context, their CV is enriched with new experiences, their knowledge of a foreign language (s) is improved, and after graduation, they become a competitive workforce. Teaching / scientific, artistic and non-teaching staff gain international experience through mobility, improve themselves, participate in active professional development, and increase the quality of the working environment. In the last 15 years, the University of Sarajevo has had over 2,500 outgoing mobility while hosting more than 1,500 international students, teaching / scientific, artistic and non-teaching staff. The mobility of students and staff significantly improves both the quality and the professional standard of UNSA activities. It indirectly contributes to the development and transformation of society as a whole. Through the integration of UNSA, many processes are uniform and simplified, but still, the heterogeneity and specificity of each organizational unit are present. In addition to all the benefits of student mobility, the most significant administrative challenge is the equivalence and recognition of ECTS credits earned at foreign institutions upon return to home institutions. Student services are faced with many formalities around keeping registers and other administrative forms that need to be tailored to exchange students. The current legal regulations in higher education do not value participation in mobility programs, which is undoubtedly not motivating for students and staff to get involved in them. On the contrary, the current vague legal framework and administrative barriers are significantly demotivating for students as they lose a semester or school year due to participation in mobility programs. It is necessary to develop more adequate regulations that will encourage more frequent, productive, more straightforward and better implementation of academic mobility for students. This could be achieved through participation in programs intended for international students (one-year specialist study, master's degree, dual education, summer schools, etc.). It is necessary to develop mechanisms for adequate evaluation of mobility for teaching, artistic and scientific staff of UNSA, which is particularly important for advancement to higher academic titles. It is also crucial to promote the exchange of administrative staff, which is often unjustifiably neglected, to improve the administrative processes at UNSA and its (sub) organizational units. To achieve this, we should be focused on developing cooperation with potential partners interested in administrative / non-teaching staff mobility.
Gender equality is a crucial issue for the 21st century society, which implies the responsibility of universities to critically review the current situation, identify social circumstances in which education takes place, and creatively design ways in which they can change social reality. Considering the imperatives of gender-inclusive education, this research is focused on the problem of horizontal gender segregation and its reflection on vertical segregation. The examination starts with insight into the general situation in higher education institutions in BiH to pay special attention to the field of social sciences at the University of Sarajevo. Based on the meta-analysis of available secondary data, the analysis primarily determines the 'diversity index' in this area, and identifies the specifics of scientific fields and the differences between them.
While distributed generators (DGs) can reduce carbon dioxide emissions, they can also cause disturbances and lead to power quality (PQ) issues, with harmonic voltages being an important parameter to consider. In this paper, the impact of 14 connected photovoltaics (PVs) and a small hydropower plant (sHPP) on harmonic voltage distortions in a real medium voltage (MV) and low voltage (LV) distribution network in Bosnia and Herzegovina was analyzed. Simulation tools carried out by DigSILENT PowerFactory offer a wide range of advantages that give system operators the ability to have insight into PQ behavior in the presence of intermittent renewable energy sources (RES). Due to the inverter-based electricity generation, PV power plants inject harmonics into the LV network. The impact is relatively small and does not violate the limits from the European PQ standard EN 50160 due to the relatively small power of the modelled existing PVs. However, integrating additional PVs could lead to a violation of limits. Therefore, where a large power of PV power plants is installed, if it is possible to integrate sHPP, they will contribute to the reduction of generated harmonics without the need to reduce the power of PV. The contribution of this paper is that it compares the impact of different power generation technologies on harmonic voltages using data from a real network rather than a test network.
Control design for multi-rotor aerial vehicles (MAVs) is quite challenging problem due to their nonlinearitles, unknown dynamics, parametric uncertainties, an underactuated property, a nonlinear coupling dynamics and external disturbances. This paper introduces a first order sliding mode control (FOSMC) for robust stabilization of an under-actuated quad-rotor unmanned aerial vehicle (UAV) operating in the presence of external disturbances. The proposed FOSMC guarantees a finite time convergence of the system trajectories to the sliding surface. Obtained simulations show that the FOSM based approach improves robustness properties compared with the concurrent techniques, and enhance tracking performance of the quad-rotor UAV exposed to external disturbances.
