    This research aims to investigate the physical and mechanical properties of soft soil stabilized using industrial wastes, namely fly ash and rice husk ash. For this purpose, 6 (six) variations in the composition of fly ash (F), lime (L), and rice husk ash (R) were prepared. The variations in sample composition are SFLR1 (F: 15%, L: 2.5%, R: 5%), SFLR2 (F: 20%, L: 2.5%, R: 5%), SFLR3 (F: 25%, L: 2.5%, R: 5%), SFLR4 (F: 15%, L: 5%, R: 10%), SFLR5 (F: 20%, L: 5%, R: 10%) and SFLR6 (F: 25%, L: 5%, R: 10%). Meanwhile, soft soil was obtained from Banjarmasin City in South Borneo. The sample's physical properties were analyzed using the Atterberg limit test. Moreover, the California Bearing Ratio (CBR) and direct share tests are conducted to assess the sample's mechanical properties. The research results can provide confidence that fly ash, lime, and rice husk ash have the potential to improve the physical and mechanical properties of Borneo soft soil. The results of the Atterberg limit test show that industrial wastes can lower the liquid limit and increase the plastic limit; thus, the soil plasticity index decreases. As for the CBR test results, the untreated soft soil bearing ratio value of 1.4% can be increased to 2.6% after being treated with industrial wastes. In addition, using industrial wastes also decreases the swelling of the soil. Moreover, it can be seen that greater use of fly ash can improve the mechanical properties of the soft soil. However, increasing the composition of lime and rice husk ash can reduce the mechanical properties of the soft soil. Based on the experimental results, it is proposed to use SFLR3 as soil stabilization mixtures.

    A globális platformgazdaság iparági értéke a 21. század második évtizedének végére meghaladta a 7 billió amerikai dollárt. A platform gazdaság által termelt bevétel az Európai Unióban közel ötszörös növekedést produkált a 2016-2020 közötti időszakban, azáltal, hogy volumenének növekedése 3 milliárd euróról 14 milliárd euróra változott. Mindazonáltal a platform üzleti modell és munka behatárolása, jogi szabályozása és ellenőrizhetősége, megfeleltethetősége, innovatív voltából adódóan, globális konszenzus, valamint precedens hiányában világ- és európai szinten is megoldatlan.  A cikk célkitűzése a platform gazdaság, valamint a platform munka körülményeinek, szabályainak és gyakorlatban való alkalmazásának a meghatározása, nemzetközi (angol nyelvű, többségben európai) szekunder információkra támaszkodva, ezáltal a problémák és nehézségek feltárása, valamint előnyeinek és hátrányainak tárgyalása.

    In an increasingly complex and volatile business environment, organizational project risk management plays a critical role in determining the chances of project success. Project management has become a common tool in the hands of large organizations for executing development and improving their production cycles in a more carefully planned way. However, the future is often hard to predict, and unexpected events may occur which could have been avoided with the use of the right tools and mindset. This comprehensive research study aims to showcase the importance of continuous risk management in organizations and highlight how risk management contributes to successful project outcomes. By synthesizing information from 59 high-quality publications from Scopus and Web of Science, the research describes various risk mitigation methodologies used across diverse fields, and explores potential obstacles faced by project managers when executing risk management strategies. The primary research of the study builds upon a survey conducted with 181 experienced project managers across various industries to gain deeper insights into their risk management approaches and the constraints they may encounter. Additionally, the study seeks to analyse the value of obtaining project management certificates in relationship with led projects’ length and budget. Employing SPSS, the research presents descriptive statistics, regression, and correlation calculations to further analyse the data gathered. The aim of the research is to draw attention to the significance of continuous risk management, propose effective methodologies, identify and mitigate potential challenges, and shed light on the potential benefits of having certifications in the field of project management.

    Entrepreneurship, which people can have without formal economic education, is a tendency acquired through upbringing in the family, competition in school, implies risk and constant self-affirmation through the acquisition of profits and losses, so that it represents the sum of successes and failures, victory and defeat. In the last thirty years, female entrepreneurship has been developing more and more, especially in less developed countries, the reason for such growth is primarily reflected in the promotion of equality between men and women, the right to education, and the development of democracy. Female entrepreneurship is a significant factor in economic development, so the national economy becomes richer. The subject of this research are the entrepreneurial climate in the Balkans compared to the world in terms of female entrepreneurship, what is the role of the family in starting a small business, as well as its survival and growth. In the study the results of previous research in this area. The research method is based on a comparative analysis of studies dealing with this problem from the territory of Balkans. It can be concluded that in the Balkans, female entrepreneurship is still in its infancy, it is about a very small percentage of female entrepreneurs, although according to research, it is evident that there has been no major progress in the last 15 years. Recommendation In the countries of the Balkans, there is a good entrepreneurial climate for the development of female entrepreneurship, especially because women can work from home, and in the future it is necessary to go in this direction.

    The tourism industry in China has undergone significant changes due to globalization, technology, and changing consumer preferences. This perspective article, based on a systematic literature review, examines examines trends, challenges, and opportunities in inbound and outbound tourism in China, focusing on the industry's dynamism. Both inbound and outbound tourism have been negatively impacted by the COVID-19 pandemic, which has prompted new strategies and environmental adaptations. China has changed its priorities within the country to encourage domestic travel and support local firms. The rise in internationalisation and the growing middle class in China have led to an unprecedented rise in outbound travel. Chinese travellers are affecting travel habits and spending all around the world in the tourism sector. Language barriers, cultural differences, and safety concerns are some of the challenges that come with travelling abroad. To reach its full potential, China needs to adapt to the shifting global environment and take into account the specifications and preferences of both inbound and outgoing tourists.

    A vasúti közlekedés zajemissziója kiemelkedő fontosságú téma, mivel hatással van mind a környezetre, mind az emberek egészségére és életminőségére. A zajszennyezés számos forrása között a vasúti járművek és az infrastruktúra jelentős szerepet játszanak. A vasúti zajemisszióval kapcsolatban megállapítható, hogy a zajhatásokat számos tényező befolyásolja. Ilyen tényezők lehetnek a vonatok sebessége, a pálya állapota, a vontatási technológia és az alkalmazott zajcsökkentő intézkedések. A zajterhelés negatív hatásai közé tartozik az alvászavar, a stressz, és a mentális egészségromlás. Ezenkívül befolyásolja a lakott területeken élők életminőségét és az ingatlanok értékét is. A vasúti közlekedés zajemissziójának csökkentése kulcsfontosságú az egészségesebb és fenntarthatóbb városi környezet kialakításában. Ennek érdekében fontos a modern zajcsökkentő technológiák alkalmazása, az infrastruktúra fejlesztése és a zajvédelmi intézkedések hatékony implementációja. A közlekedési hatóságoknak és vasúti vállalatoknak együtt kell működniük a zajmentesebb vasúti közlekedés megvalósítása érdekében, az emberek életminőségének javítása és a környezetvédelem érdekében.
