Introduction. The objective of the presented research is to characterize hope in the situational dimension, i.e., health, in the patients with cancer in the terminal phase of the disease, being treated in hospices and palliative care centers. Hope is very important for all the patients, especially for patients with cancer in various phases of the disease. Giving up on oncologic therapy and causal treatment is often associated with a transition into palliative care. When death and a loss of values become a threat, the individual has got hope to rely on. Material and Methods. The study relies on the Test to Measure Hope in the Health Context (NCN-36) by B.L. Block. 246 patients in the terminal phase of cancer participated in the study. Results. The internal structure of hope of recovery in the patients’ group was varied. The patients showed low levels of hope of recovery since they do not believe in the effectiveness of treatment. They were also not convinced of the effectiveness of modifications in dieting, lifestyle, or the use of nonconventional medicine. They trusted the doctor in charge and were moderately satisfied with the therapy in use. The intensity of hope of recovery was on the low level in the patients in the terminal phase of cancer. Age, sex, place of living, and marital status had a significant influence on the level of hope of recovery. Variables such as living on one’s own or living with one’s family, socioeconomic status, education, or profession did not affect the level of hope of recovery. Conclusions. The presented results allowed as to conclude that the assessment of hope in terminally ill cancer patients can be considered as one of the important tools enabling the personalization and the improvement of palliative care.

In this study, drying characteristics, kinetic modelling, energy and exergy analyses of a convective hot air dryer are presented for water yam. The drying experiments were carried out at temperature levels of 50, 60, and 70°C and slice thicknesses of 3, 6, and 9 mm. The effects of drying variables on the drying rate (DR), moisture diffusivity (Deff), activation energy (Ea), energy utilization (EU), energy utilization ratio (EUR), exergy loss (EXL), exergy efficiency (EXeff), improvement potential (IP), and exergetic sustainability index (ESI) were investigated. The results showed that increasing air temperature increased the DR, Deff, EU, EUR, EXL, EXeff, IP, and ESI, while increasing the slice thickness increased Deff and Ea, but decreased the DR. The highest Deff and Ea values were 4.2 × 10−8 m2/s, and 53 KJ/mol, respectively. EU and EUR varied from 10 to 150 J/s and 0.39 to 0.79, respectively. EXL and EXeff varied between 2 and 12.5 J/s and 58 to 75 %, respectively. Midilli’s model had the best performance in predicting the moisture ratio of water yam with coefficient of determination (R2 = 0.9998), root mean square error (RMSE = 0.0049), and sum of square error (SSE = 0.0023).

The aim of this study is to characterize the cognitive aspect of the semantic space of hope in patients in the terminal stage of cancer. This was confirmed in the research on hope by C. R. Snyder and B. Schrank. Hope is of great importance in all the great world religions and belief systems, both as regards a personal God or impersonal deities. Hoping is a human capacity with varying affective, cognitive and behavioral dimensions. Psychological, pedagogical (particularly in the framework of special needs pedagogy and thanatological pedagogy) and theological reflection on hope can provide support for dying people. In order to conduct the research, the semantic differential research method was selected. The research technique employed was a therapeutic conversation, and the research tool was the B.L. Block’s DSN-3 test. The DSN-3 test allows one to assess hope in the semantic space in three aspects: cognitive, emotional and functional. For the purposes of this study, only the cognitive aspect was taken into account. The study was begun on 1 April 2010 and ended in the last days of December 2020. It included 110 male patients in the terminal stage of cancer. The youngest respondent was 19 years old and the oldest was 94 years old. The surveyed men most often perceived hope in the semantic space in the cognitive aspect as more true, wise, meaningful and real than false, stupid, meaningless and deceptive. Their attitude to hope was, therefore, more affirmative than negative. The research did not reveal the importance of the age of the respondents on the degree of affirmation/negation of hope in the cognitive aspect in the semantic space; however, men in the period of late maturity and professional activity expressed the lowest level of the affirmation of hope. It is worthwhile to conduct further research concerning hope in other aspects (especially emotional and functional) in the semantic space in order to use the obtained results to consider what to take into account when providing patients in the terminal stage of cancer with better personalized holistic care than before.

To ensure the progress of sustainable development and overcome threats to national security, the development of tools for balancing ecological, economic and energy aspects of economic activity acquires special importance. This study is related to the influence of choosing different functional elements of transport taxes on their effectiveness in ensuring national security. For calculations, panel regression modelling with panel-adjusted standard errors based on the use of the Durbin–Watson test using dummy variables was chosen. The assessment involves the selection of the main factor variable (tax revenues from transport taxes, as well as an additional dummy variable) and compliance with a country’s transport taxation system, with a certain criterion for its application. The resulting criterion was chosen as an integral indicator of national security, which summarizes the parameters of environmental footprints, economic growth, energy efficiency and security. Calculations were made for nine countries (i.e., the Czech Republic, Finland, France, Ireland, Israel, Portugal, Romania, Slovakia and Turkey) for the period 1996–2019. The calculations proved that the establishment of transport taxes, depending on the type and weight of the car, increases their effectiveness on ensuring national security or, depending on the cost and age of the car, weakens such effectiveness. The use of emissions generated by the car, its capacity and its type of fuel requires additional research; the obtained results did not allow for unambiguously determining their impact on the effectiveness of transport taxes. The conducted research forms the basis for choosing the optimal design of transport taxes to ensure the maximization of their regulatory effectiveness. The developed approach can be extended to evaluate the effectiveness of other environmental taxes.
