    Over-attachment to work is an increasingly common phenomenon in the lives of people in organisations, and can also be a condition of work addiction. Whoever becomes involved in an organisation, be it a subordinate or even a manager, work addiction has a number of negative consequences at both individual and organisational level. Without being exhaustive, work addiction can have an impact on organisational performance, organisational effectiveness, workplace conflict, career prospects, health maintenance. In this paper, we aim to highlight the most relevant publications from the last five years to report on the impact in an organisation when work addiction arises among subordinates or managers, and how different leadership styles are associated with work addiction among organisational members. The publications were retrieved from Google Scholar and Scopus, and the results of 19 articles are presented in this paper after a review of 263 papers retrieved. The results show that transformational, servant and ethical leadership styles have ambiguous effects on work addiction, unlike laissez-faire or abusive leadership styles, the former enhancing and the latter reducing the incidence of work addiction in an organisation. Work addiction of managers also has a dual effect: on the one hand, it can enhance creativity, but it can also increase turnover among subordinates. Social support from the manager can be an antidote to subordinates' work addiction, but this effect may be modified by the quantity and quality of interaction between manager and subordinate, the sense of meaningfulness of the work, or even the organisational culture. Overall, the manager, as a key actor, can have an impact on work addiction in the organisation, but there is not always a consistent position in the research on the cases and the way in which this is done, which calls for further research in the future.

    Solid waste management remains a pressing environmental challenge in both developed and developing nations. Recycling has been promoted globally as a key pathway to sustainability, yet recycling rates often provide only a partial picture of performance. In many contexts, challenges such as poorly regulated recycling policies, informal sector dominance, and practices that prioritize profit over environmental sustainability limit progress towards Sustainable Development Goal (SDG) 12.5.1, which tracks the national recycling rate. This study investigates the extent to which recycling rates reflect sustainable waste management and identifies the underlying factors that influence their effectiveness. The major objective of this study is to evaluate recycling rates as an indicator of sustainable waste management. This is further specified by: (i) examining recycling practices in selected countries (Germany, South Korea, USA, Brazil, and India), (ii) identifying key drivers and barriers that influence recycling performance, and (iii) assessing the implications of recycling rates for sustainable waste management systems. The study employed a mixed-methods approach, combining secondary data analysis, comparative country assessment, and policy review. Results show that recycling rates are useful but insufficient as a stand-alone measure of sustainability, since they are influenced by broader elements such as policy enforcement, economic incentives, public participation, and market structures. The findings highlight that Nigeria’s recycling rate remains significantly low compared to leading economies, underscoring the need for integrated waste management reforms. This research contributes to environmental management discourse by demonstrating that while recycling rates provide a benchmark for SDG 12.5.1 monitoring, they must be interpreted alongside contextual drivers to ensure meaningful progress towards sustainable waste management.

  • Comparative Study of Surface Treatment Procedures for Dental Implants

    Nowadays, the most common type of implant in dentistry is a partial tooth replacement, such as a crown, or a complete tooth replacement. Today, many manufacturers offer implants made of a wide variety of materials and designs. These restorations must meet strict standards, one of the most stringent being surface roughness. Since proper bone-to-implant contact only occurs with adequate surface roughness, several methods are used to achieve the correct value. After reviewing the results of experiments carried out by several research groups, it is concluded that the surface roughness, the shape of the implant fixation screw, the shape of the thread and the thread elevation used to achieve the desired roughness together determine the success of the implantation. The average surface roughness required for osseointegration is considered to be optimal for values between 1 and 100 µm. In most cases, the surface roughness of commercially available dental prostheses is Ra 1-2 µm, but this can be modified by various grinding, acid etching and polishing processes to suit the application. Acid etching is a common technique for roughness reduction, which is the most effective in reducing surface roughness of dental restorative materials (mostly titanium alloys), thus bringing the roughness within the desired range. The result of acid etching is influenced by the concentration of acid, the temperature of the acid bath and the time spent in the acid. The acid used for the surface treatment is important and is most commonly sulphuric acid, hydrochloric acid or hydrogen fluoride (HF) and combinations of these. The study shows that the most optimal results are obtained with HF. Replacements are nowadays largely made by additive manufacturing, which allows for customised replacements and, due to dimensional accuracy, reduces the time and cost of post-processing, i.e. the surface treatment can be used to achieve the desired surface roughness and size at the same time. As a result, newer materials are being used for clinical prostheses and surface treatment should be applicable to all materials. The most optimal solution is a combination of grit blasting and acid etching. With this technology, the surface roughness for all materials reaches the optimum value of 1-100 µm, sometimes 1-2 µm, but can be further reduced below 1 µm by polishing. The study investigates the role of surface roughness, the surface roughness should only be reduced up to a certain value, approximately 0.5 µm, as smooth surfaces have limited or no potential for osseointegration.

    The aim of this article is to compare the clusters formed by the correlation distances between the agricultural and the energy commodity price returns in different periods of time. The energy and agricultural markets have become more interlinked in the past ten years, which can be attributed partly to the increased usage of biofuels. According to the results of this research, after the global financial and economic crisis of 2008/09, the relationship has become tighter between the agricultural commodity prices and the price of the crude oil. Based on the hierarchical clustering, the relationship between crude oil and sugar, and especially between crude oil and vegetable oils has become stronger. These results support the hypothesis of a more interconnected agricultural and energy market after 2013. Furthermore, the emerged relationship of crude oil with the vegetable oils may indicate the connecting role of biofuels, since biofuels require agricultural input materials, partly vegetable oils. However, the role of biofuels in the present analysis requires further researches.

    Danube is the main river of Hungary. Danube and its floodplains and oxbow lakes are operating as ecological corridors, although their industrial, logistic and touristic role is not negligible. It is well known, that from the source to the estuary of the river Danube there are many industrial facilities. This heavy industrial pollution had effected on the water quality. The most dangerous components of the sewage water of these facilities are heavy metals, which can be found in the water as well as in the sediment. These toxic elements can cause significant health risks, because they can accumulate in the food-chain. The main aim of our research is to investigate the accumulation rate of the heavy metal content of the river sediment in the different parts of the test plants. The main sampling place of our research was a sediment dump was created by excavation from the Open Beach of Dunaújváros in 2009. During our measurements we analysed the cadmium, nickel, lead, chromium, copper and zinc concentration of the sediment and the plants. The test plants, which are growing on this sampling place, were parella (Rumex patientia), perennial rye-grass (Lolium perenne), sedge (Carex riparia), bistort (Persicaria maculosa). The extraction of the heavy metal content of the samples was made according to the MSZ Hungarian standard. The concentration of heavy metals were analysed with AAS (atom absorption spectrometer). According to our results we determined that parella could accumulate cadmium, nickel, chromium and zinc in its upper stem, on the other hand bistort could accumulate these elements mainly in its leaves. These information will be important in the case of the in-situ remediation of a polluted area in the future.

    Nowadays, one of the most interesting parts of sociology is the research of the rural areas’ specific features. Within these studies the rural areas ability for survival and to retain forms an important basis. A basic pillar of these, that the youth from these areas become sufficiently motivated to return to their rural homeland after finishing their studies and be able to redound the local social and economic development. Sadly, we experience the opposite of it. Young generations are fleeing to large cities and in medium or long term it leads to the decay of these involved settlements; in worst case scenario the results can be irreversible. In close relation with the aforementioned, we have to mention the specific behaviour of the local – rural – elite, which can be the source of further problems. In the course of our research, we wanted to investigate, that what is the reason that university students, who are studying in large cities don’t want to return or move to rural areas. Furthermore, we tried to give an inside view about their opinions of rural areas and the life in the countryside.

    In our study, we analyse various researches dealing with quality aspects of sport services, and different quality models related to the interpretation of quality. The results which were obtained in the framework of primary research activity present the opinions of students from five different research universities. Sport services’ operation and sustainability are determined by market regulations, as parts of the service industry. Considering that the university leisure sports services take place in a competitive environment, the universities often have to compete with external sports service providers for achieving confidence of the young generations. For the qualitative tests, we used the QSport-14 measurement scale, which is generally applied by sports centres. This scale investigates the sports services according to three different aspects: (1) instructors, (2) infrastructural facilities and equipment and (3) offered sport programs. We have adapted the measurement scale to the university environment because of the differences and special characteristics of external sports service providers and university sports services. In addition, we analysed the factors influencing recreational sports, and we also examined that what changes would be needed in order to improve the quality of recreational sport activities in higher education.

    Nowadays, we can observe an increasing trend in the spread of non-communicable diseases. It is important to highlight the social factors that negatively affect health. Determinants includes income, education and the research-relevant working and living conditions. From a labor market perspective, unemployment and poor working conditions are a significant responsibility for the deterioration of mental and physical health. Health is also affected by employment conditions. Extended working hours have been shown to be harmful to health. Poor health has generates poorer work performance, a higher rate of sick leave, and higher health care costs. My primary goals in my research was to explore the labor market impacts of workplace health promotion and guidelines for corporate health promotion. Within health promotion, physical activity has played a prominent role. I’ve been used secondary data collection during my research. I have been performed a traditional literature analysis based on domestic and international studies. My results are suggest that the workplace health promotion has more positive labor market effects than increasing productivity and reducing absenteeism and health care costs. It is important to mention that health promotion could bring benefits to both employers and employees. Regarding corporate guidelines, there is no new approach directive other than the older literature sources. thus, it may be worthwhile to develop a new and different corporate process for effective workplace health promotion.
