Economic importance of marinas on the Polish Baltic Sea coast

PURPOSE: This paper identifies the economic importance of the Polish Baltic Sea coast marinas. The investigated marinas are among the most prominent port structures and represent each section of the sea coast. In determining the economic impact of marinas, three effects were identified, i.e., direct, indirect and induced. These effects are discussed in terms of output, added value and employment.DESIGN/METHODOLOGY/APPROACH: The economic importance of marinas was determined using an input-output method, often referred to as the Leontief model. The extent of the economic impact of the port was referred to the coastal sub-regions, i.e., Koszaliński, Słupski and Gdański, which are NUTS 3 territorial units. The regionalisation of the national input-output table was carried out using the Flegg location coefficient (FLQ). A comparative analysis was carried out, taking marinas in Spain and Italy as the object of comparison. The research was based on local statistics and survey results.FINDINGS: The strength of the impact of the studied marinas is less than their initial economic impetus. The direct and induced effect had the most significant impact on the economy of the sub-regions, with the indirect effect being of minor importance. The greater strength of the impact of the Valencia Region's marinas may result from the input-output table regionalisation technique adopted and the greater self-sufficiency of port cities in Spain. The dominance of the direct effect should be linked to the extensive network of links created by nautical tourism. The minor importance of the indirect effect is due to the limited inter-sectoral linkages. On the other hand, the lower significance of the induced effect in the case of Polish marinas is related to the lower level of development of the national economy and the failure to include investment expenditures in the model.PRACTICAL IMPLICATIONS: The results of the study provide information for decision-makers on the economic importance of marinas. They allow investment funds to be concentrated on areas with the most significant impact on the local economy.ORIGINALITY/VALUE: The authors of this article were the first in the country to address the economic importance of marinas using the input-output method.peer-reviewe

Global Ban on Plastic and What Next? Are Consumers Ready to Replace Plastic with the Second-Generation Bioplastic? Results of the Snowball Sample Consumer Research in China, Western and Eastern Europe, North America and Brazil

Plastic can be used for many things and at the same time is the most versatile material in our modern world. However, the uncontrolled and unprecedented use of plastic comes to its end. The global ban on plastic brings significant changes in technology but even more so in civil perception—changes taking place before our eyes. The aim of this study was to find answers to the questions about the readiness of consumers for a global ban on plastic. Within the research, the differences in consumer acceptance in countries in Europe, South and North America and Asia and the expression of social readiness to change attitudes towards plastic food packaging were analyzed. This work sketches the legal framework related to limiting the use of one-use food packaging made of fossil raw materials at the level of the European Union, Poland and Portugal but also at the level of the two largest economies in the world, China and the United States, as well as lower-income countries, e.g., Ukraine and Brazil. The survey results were analyzed using descriptive and inferential statistics. The performed study demonstrates that, in in all the surveyed countries, appropriate legal acts related to the reduction of plastic in everyday life are already in place. Furthermore, this work demonstrates the full understanding of plastic banning in all surveyed countries. Consumers are aware that every effort should be made to prevent the world from drowning in plastic waste. Society is, in general, open to the use of bioplastics produced from the second-generation resource if second-generation bioplastics contribute to environmental and pollution reduction targets

New Medicine Service as support for medication adherence by chronically ill patients

Effective management of the treatment for chronically ill patients is a multifactorial process. The crucial is an accurate diagnosis, appropriate and well-designed pharmacotherapy, as well as patient medication adherence. Adherence is defined as the extent to which patients are able to follow the general practitioner's recommendations for the prescribed treatments. Patients’ reasons for deviating from the treatment plan are diverse and may be intentional or unintentional. They may be non-adherent during different stages of their treatment. Some patients may decide not to fill physician prescriptions and not start their treatment at all. Patients may use more or less than the prescribed medication or use their treatments at the wrong time. They may also discontinue therapy prematurely. The common reasons for medication non-adherence may include lack of symptoms, improvement in health, in patients’ subjective opinion, fear of potential side effects, long-term conditions, multimorbidity, and polypharmacy. Poor knowledge about medicines can also lead to severe consequences such as non-adherence. Several interventions may contribute to improved adherence. The current legislation in pharmaceutical care enables registered pharmacists to intervene successfully when a medicine is prescribed, increase effective medicine taking for the treatment of a long-term condition, and optimize the therapy; they also may offer the patient, opportunistic advice on healthy living or public health topics in line with the promotion of healthy lifestyles. One of the proposed pharmaceutical care services for Polish patients – the New Medicine Service, was introduced in England in 2011 as support for subjects starting a newly initiated medication for long-term treatment. The article presents the assumptions and goals for this pharmaceutical consultation in polish system of health care, discusses the interview schedule and forms, and describes the service's beneficial contribution to better medication adherence by chronically ill patients

Verification of electron beam parameters in an intraoperative linear accelerator using dosimetric and radiobiological response methods

Background: The availability of linear accelerators (linac) for research purposes is often limited and therefore alternative radiation sources are needed to conduct radiobiological research. The National Centre for Radiation Research in Poland recently developed an intraoperative mobile linac that enables electron irradiation at energies ranging from 4 to 12 MeV and dose rates of 5 or 10 Gy/min. The present study was conducted to evaluate the electron beam parameters of this intraoperative linac and to verify the set-up to evaluate out-of-field doses in a water phantom, which were determined through dosimetric and biological response measurements. Materials and methods: The distribution of radiation doses along and across the radiation beam were measured in a water phantom using a semiconductor detector and absolute doses using an ionisation chamber. Two luminal breast cancer cell lines (T-47D and HER2 positive SK-BR-3) were placed in the phantom to study radiation response at doses ranging from 2 to 10 Gy.  Cell response was measured by clonogenic assays. Results and Conclusion: The electron beam properties, including depth doses and profiles, were within expected range for the stated energies. These results confirm the viability of this device and set-up as a source of megavoltage electrons to evaluate the radiobiological response of tumour cells

The Economic Importance of Offshore Wind Energy Development in Poland

The European Union’s climate policy aims to reduce greenhouse gas emissions by 55% by 2030 and to achieve climate neutrality by 2050. One of the instruments for achieving these climate goals is the development of offshore wind energy. Unfortunately, Poland, as one of the few European Union countries with access to the sea, does not have offshore wind farms yet. The purpose of this article is to determine the importance of offshore wind energy for the development of Poland based on the example of two sea regions: the West Pomeranian and Pomeranian Voivodeships. This article uses the input–output method to determine the economic effects of offshore wind power. The region’s share in the supply chain was determined based on the location of the offshore wind energy sector. A comparative analysis with the Saint-Brieuc offshore wind farm in France made it possible to show the differences between the studied locations. The supply chain share of the regions surveyed was 2.28% and 6.00% in the CAPEX phase and 5.98% and 8.23% in the OPEX phase. The annual average global value in the CAPEX phase at the country level was EUR 2793 million, and at the regional level, EUR 243 million and EUR 663 million. In the OPEX phase, the corresponding values are EUR 2106 million, EUR 223 million and EUR 663 million. The average annual employment in the CAPEX phase at the national level amounted to 26,323 jobs and at the regional level, 1953 and 5804. In the OPEX phase, employment amounted to 4790, 558 and 751 jobs, respectively. On the other hand, the average annual value added in the CAPEX phase at the national level was EUR 1221 million, and at the regional level, it was EUR 106 million and EUR 290 million. In the OPEX phase, it was EUR 920 million, EUR 97 million and EUR 239 million, respectively. While not all of the findings are conclusive, in general, the domestic offshore wind industry has weaker economic linkages and lower wage levels than the location adopted for comparison. It uses more labour-intensive economic sectors with lower OPEX value added. The results of the analyses presented in this paper are of crucial importance not only for Poland, as their advantage is the possibility to present, from an economic point of view, the profitability of this type of investment in general

Effect of miR-195 inhibition on human skeletal muscle-derived stem/progenitor cells

BACKGROUND: Application of a circulating miR-195 inhibitor could be a helping factor in in vitro model of human skeletal muscle- derived stem/progenitor cells (SkMDS/PCs). Previously, miR-195 expression has been reported to be a negative factor for myogenesis. AIMS: The aim of the study was to obtain anti-apoptotic and anti-aging effects in in vitro cultured myoblasts and to improve their ability to form myotubes by suppressing miR-195 expression. METHODS: Human wild-type (WT) SkMDS/PC cells incubated with control (nonspecific) miRNA inhibitor and miR-195-inhibited SkMDS/PCs were studied. Functional assays (myotube formation and cell ageing), antioxidant, and myogenic gene expression analyses were performed at two time points, at the 7th and 11th cell passages. RESULTS: Myotube formation was found to be almost 2-fold higher in the miR-195-inhibited SkMDS/PCs population (p&lt;0.05) compared to WT cells. miR-195 inhibition did not appear to affect cell ageing or rejuvenate human SkMDS/PCs. Antioxidant (SOD3 and FOXO) gene expression was augmented in the miR-195-inhibited SkMDS/PCs population, but no positive effect on the remaining antioxidant genes (SOD1, SOD2, and catalase) was observed. A significant increase in MyoD gene expression with a concomitant decrease in MyoG (p&lt;0.05) was further documented in miR-195-inhibited SkMDS/PCs compared to WT cells (11th cell passage). CONCLUSIONS: The performed studies may lead to the preconditioning of myogenic stem cells to extend their potential for pro-regenerative activity. miR-195 inhibitor may serve as conditioning factor augmenting selective antioxidant genes expression and proliferative potential of SkMDS/PCs, but not having an impact on cell aging and/ or apoptosis
