Long term monitoring and connection between topography and cloud cover distribution in SerbiaAleksandar Valjarević, Cezar Morar, Jelena Živković, Liudmyla Niemets, Dušan Kićović, Jelena Golijanin, Milena Gocić, Nataša Martić Bursać, Ljiljana Stričević, Igor Žiberna, Nikola Bačević, Ivica Milevski, Uroš Durlević, Tin Lukić, 2021, original scientific article Abstract: The use of weather satellite recordings has been growing rapidly over the last three decades. Determining the patterns between meteorological and topographical features is an important scientific job. Cloud cover analysis and properties can be of the utmost significance for potential cloud seeding. Here, the analysis of the cloud properties was conducted by means of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite recordings. The resolution of used data was 1 km2 within the period of 30 years (1989-2019). This research showed moderate changing of cloudiness in the territory of Serbia with a high cloudiness in February, followed by cloudiness in January and November. For the past three decades, May has been the month with the highest cloudiness. The regions in the east and south-west, and particularly in the west, have a high absolute cloudiness, which is connected with the high elevation of the country. By means of long term monitoring, the whole territory of Serbia was analyzed for the first time, in terms of cloudiness. Apart from the statistical and numerical results obtained, this research showed a connection between relief and clouds, especially in the winter season. Linear regression MK (Mann-Kendall test) has proven this theory right, connecting high elevation sides with high absolute cloudiness through the year.

2. The IHI Rochester Report 2022 on healthcare informatics research : Resuming after the CoViD-19Carlo Combi, Julio C. Facelli, Peter Haddawy, John H. Holmes, Sabine Koch, Hongfang Liu, Jochen Meyer, Mor Peleg, Giuseppe Pozzi, Gregor Štiglic, Pierangelo Veltri, Christopher C. Yang, 2023, review article Abstract: In 2020, the CoViD-19 pandemic spread worldwide in an unexpected way and suddenly modified many life issues, including social habits, social relationships, teaching modalities, and more. Such changes were also observable in many different healthcare and medical contexts. Moreover, the CoViD-19 pandemic acted as a stress test for many research endeavors, and revealed some limitations, especially in contexts where research results had an immediate impact on the social and healthcare habits of millions of people. As a result, the research community is called to perform a deep analysis of the steps already taken, and to re-think steps for the near and far future to capitalize on the lessons learned due to the pandemic. In this direction, on June 09th–11th, 2022, a group of twelve healthcare informatics researchers met in Rochester, MN, USA. This meeting was initiated by the Institute for Healthcare Informatics—IHI, and hosted by the Mayo Clinic. The goal of the meeting was to discuss and propose a research agenda for biomedical and health informatics for the next decade, in light of the changes and the lessons learned from the CoViD-19 pandemic. This article reports the main topics discussed and the conclusions reached. The intended readers of this paper, besides the biomedical and health informatics research community, are all those stakeholders in academia, industry, and government, who could benefit from the new research findings in biomedical and health informatics research. Indeed, research directions and social and policy implications are the main focus of the research agenda we propose, according to three levels: the care of individuals, the healthcare system view, and the population view.

3. Impact of transport trends on sustainability in the Western Balkans : a future-oriented business sector perspectiveTomislav Letnik, Katja Hanžič, Matej Mencinger, Drago Sever, 2024, original scientific article Abstract: Abstract This study examines the impact of emerging transport trends on the Western Balkans and their potential to improve the sustainability and efficiency of the transport sector in the region. In the context of global efforts to reduce environmental impacts and improve transport safety, the study aims to better understand the perspective of the business sector in order to align strategic planning for the introduction of new transport technologies and practices with the expectations of the business sector. Using a questionnaire-based survey on the Mentimeter platform, the study gathers insights from 49 transport and logistics experts. The analysis uses violin plots and heat maps to visualise the expected impact of the identified trends. The results show a consensus among the experts that the emerging trends are likely to lead to a reduction in accidents, congestion, and emissions, while at the same time increasing operating costs and investment in infrastructure. In particular, trends such as alternative fuels, electrification, and smart city initiatives are highlighted as important drivers for reducing emissions. The study concludes that while these trends are likely to lead to the achievement of environmental and safety goals, they also lead to economic challenges as operating costs increase and significant infrastructure investment is required. The study emphasises the need for strategic investment, policy adjustments, and capacity building to lead the Western Balkans towards a sustainable transport future.

4. A framework for managing future supply chain trends: utilization of lean, agile and leagile strategiesWaleed Rashad, 2020, doctoral dissertation Abstract: The supply chain has become very essential to run any business nowadays. Throughout the history of business, the professionals have been trying always to find out the best practice, and as long as the business concept is evolved over time, the practice, methodologies and techniques of doing the business also have been evolved.
This evolvement led to the concept of supply chain initially and then later it became essential to have strategy for supply chain. The evolvement of the markets, globalization, and new technologies became very decisive subjects for building any supply chain and developing its strategy, but there are many other events that may take place which could enforce the supply chain decision makers to change the current approach of running their business.
The dynamic business environment and the possible future trends of the global markets represent a real challenge for development of appropriate supply chain strategies, like lean, agility, and leagility. Therefore, it is very important to assess how different possible strategies are suitable for the future changes of the markets? This is to enable the supply chain to be prepared with adequate strategies for different future scenarios.
To achieve this aim of preparing the supply chains for the future with adequate strategies, a deep study is done to research lean, agility and leagility, explaining the similarities and differences of these concepts. These strategies are dealing with the most important factors in supply chains; the time and the cost, what is the key reason for selecting these particular strategies lies in the fact, that they are concerned with improving the effectiveness and responsiveness in the supply chain and this is extremely important for the future.
We continued study of these strategies by development of three possible future scenarios for energy scarcity, new international monetary system, and wars. The reason of developing these particular scenarios is because they are concerned with the most important political and economic events which could happen and affect the supply chains in the future (EY, 2013; Cook, 2006; Sokov, 2015). These scenarios are established to anticipate the possible challenges which could face the supply chain strategies in the future and to evaluate the suitability of supply chain strategies for such future scenarios.
A survey of 150 supply chain professionals, who are working currently in the field of supply chain management, is done in two phases. The first phase is focusing on recognition of the opinions of surveyed supply chain professionals towards the supply chain strategies and their utilization. Based on the theoretical knowledge of the academic literature reviewed in this research, proposed scenarios, and the feedback of professionals in the survey, it was evident that supply chains’ managers need adequate framework, which will support improvement of current and future supply chain management.
Therefore, the grounded theory methodology is used to create a new conceptual framework. The core idea of the proposed framework is to improve the global sourcing practice, which consequently will enable improving the management of supply chains according to the predicted scenarios.
A second phase of survey is conducted to present the proposed framework to the supply chain professionals for evaluation. The proposed framework adds value to the global sourcing process, which enhancing the supply chain collaboration and helps to support the selected supply chain strategies for consideration – i.e., lean, agility, and leagility, to work better in the future.
The proposed framework represents scientific contribution to the supply chain strategies utilization in practice. The results of this contribution are obviously to fill the gap highlighted by the supply chain professionals in the survey, who highlighted the essential need for improvement to the supply chain collaboration globally, and this will be the basic c Keywords: Keywords: supply chain strategies, lean, agility, leagility, supply chain future trends, supply chain management, grounded theory, scenario planning, supply chain collaboration, sourcing.

5. Reviewing the narrative concerning the impact of population growth in AfricaCocou Marius Mensah, 2019, original scientific article Abstract: This article discusses the topic of population growth in Africa, a recurring theme in the era of climate change and the fight against CO2 emissions. The African continent is full of essential raw materials and encompasses the youngest population in the world. There is no doubt concerning the significant role it will play in global affairs, at a time when the world population is ageing, according to the UN statistics. In recent years, many policymakers have highlighted the necessity to deal with overpopulation, provoking moral controversial and basic human rights abuses. This article, however, proposes an opposite argumentation based on fresh data and emphasises the opportunities and challenges to take on, as the author considers "overpopulation" as more of a challenge than a sentence to underdevelopment. Though the paper mentions different issues linked to overpopulation, such as migration crisis, ecological sustainability and the UN Sustainable Development Goals, it concludes with a reminder of the importance of international cooperation as a solution to global issues.

6. Juvenile crime in the 21st century : a really escalating problem or just a media sensation? The case of CroatiaIrena Cajner Mraović, Valentina Asančaić, Dubravko Derk, 2015, original scientific article Abstract: Purpose:
The main goal of the paper is to analyse dynamics of juvenile crime and to identify long-term tendencies in the development of this negative social phenomenon in Croatia in this century.
Design/Methods/Approach:
Based on official police statistics, the analysis of the dynamics and the average rate of change are used to reveal and compare trends in reported overall, violent, and juvenile property crime in Croatia between 2000 and 2013. Model of a linear trend is used to make a prediction of future short-time trends.
Findings:
Though the total number of reported juvenile crime is stable or even slightly declining over the observed period, there are exceptional increases or declines in certain years and in certain offences, which can create the wrong impression about alarming changes. It especially applies to the oscillations of the number of reported juvenile homicide and rape, because of small absolute numbers. Substantial and significant fluctuations during the observed period, are found in reported rates for robbery and theft: there is a decrease in reported theft and increase in reported robbery.
Originality/Value:
In Croatia, but also in other post-socialist countries in Central Eastern Europe, there are general beliefs of the dramatic increase in juvenile crime rates since late 1990s. Results of this study reveal how such cursory review obscures some long-term and significant changes in juvenile crime, which are indicative when speaking about the juvenile crime under conditions of intensive social change.

7. The influence of social networking sites on recruiting human resources in the Czech republicLucie Bohmova, Antonín Pavlíček, 2015, original scientific article Abstract: Background: This paper is focused on the usage of social networking sites (SNS) for human resources departments in the process of hiring new employees. It also maps the development and influence of SNS on recruiter's behavior and customs. The main aim is to find out, whether SNS could/will replace traditional online job boards in the Czech Republic. The motivation for the research is to determine whether SNS can be used for serious and practical business purposes.
Methods: The paper presents authors’ empirical research with two interconnected instruments used for data collection: (1) Questionnaire with 15 questions devoted to usability, evaluation and comparison of SNS with job portals (N=286 HR specialists) and (2) Comparison of 3 online job advertising methods – job portals, SNS and business website.
Results: HR specialists regularly use publicly available information on candidates’ Facebook profiles. Similar results have been observed using both instruments. SNS's in the Czech Republic are not yet used by recruiters as the main tool for recruitment, however, are often used as a support tool for decision making in the final stage of recruitment. Use of SNS's by recruiters is universal; we have not found any significant differences in terms of demographics (men, women, old, young HR professionals). The rate of utilization of SNS's by recruiters in the Czech Republic is gradually increasing, but does not reach the US level.
Conclusion: Our findings confirm the rising importance of social networking sites (SNS) usage as a new recruiting technology. However, as a major player in the field of recruitment, job boards (eg. Jobs.cz) are still important. However, the expectation is that in the near future, this will change and SNS‘s may replace the job boards.

10. Survival of node-negative breast cancer patients treated at the University Medical Centre Maribor in the period 2000-2009Nina Fokter Dovnik, Darja Arko, Nina Čas-Sikošek, Iztok Takač, 2017, original scientific article Abstract: Introduction: Breast cancer is increasingly diagnosed in the early stages without regional nodal involvement. The aim of the present study was to determine the 5-year overall (OS) and breast cancer specific survival (BCSS) for patients with node-negative breast cancer treated at the University Medical Centre Maribor, and compare it with survival at the national level.
Methods: Medical records were searched for information on patients with lymph node-negative invasive breast cancer who received primary treatment at the University Medical Centre Maribor in the period 2000–2009. Information on all Slovenian node-negative breast cancer patients diagnosed in the same period was obtained from the Cancer Registry of Republic of Slovenia. Time trends in survival were assessed by comparing the periods 2000–2004 and 2005–2009.
Results: The 5-year OS and BCSS of patients treated in Maribor in the period 2000–2009 were 92.3% (95% CI, 90.5%– 94.1%) and 96.4% (95% CI, 95.2%–97.6%), respectively, and did not differ from the corresponding OS and BCSS for Slovenian patients. Although the improvement in OS for patients from Maribor diagnosed in the period 2005–2009 compared to 2000–2004 did not reach statistical significance (HR 0.73; 95% CI, 0.51–1.05; p=0.086), BCSS significantly improved over the same time periods (HR 0.53; 95% CI, 0.30–0.94; p=0.028).
Conclusions: Survival of node-negative breast cancer patients treated at the University Medical Centre Maribor is comparable to survival of corresponding patients at the national level. The rising number of long-term breast cancer survivors places additional importance on survivorship care.
