Authors: Krzysztofik Michal , Wilk Michal 
Published: April 2021

Abstract
The present study aimed to determine the effects of plyometric push-ups as a conditioning activity (CA) on high-loaded bench press performance. Two groups of resistance-trained males age (24.5 ± 2.6 years, body mass 84.8 ± 8 kg) performed one of two CA protocols: 3 sets of 5 repetitions of plyometric push-ups with a 1 min rest interval between sets (PAPE; n=12) or equal time aerobic warm-up (CONT; n=12). Four minutes after completion of the CA protocols the participants performed 3 sets of 3 repetitions of the bench press exercise at 70%1RM and 4 min rest interval between sets to assess post-activation differences in peak power output (PP), mean power output (MP), peak bar velocity (PV), and mean bar velocity (MV) between conditions. The two-way ANOVA revealed significant condition × set interaction effect for PP (p<0.01), MP (p<0.05), PV (p<0.01), and MV (p=0.02). The post hoc for condition × set interaction showed that PAPE caused a significant decrease in PP and PV for P-Set2 and P-Set3 when compared to baseline (BA). The MP and MV for the PAPE condition decreased significantly during the P-Set3 compared to BA and to P-Set1. The t-test comparisons for delta values showed significant differences between PAPE and CONT in PP for P-Set1 – BA (p<0.01), in MP for P-Set2 – P-Set1 (p<0.03) and for P-Set3 – P-Set1 (p=0.04). Furthermore, there were significant differences in PV for P-Set3 – BA; P-Set2 – P-Set1; P-Set3 – P-Set1 (p<0.01; p<0.01; p<0.02 respectively). Finally, there were significant differences in MV for P-Set1 – BA; P-Set2 – P-Set1 and P-Set3 – P-Set1 (p<0.01; p<0.01; p<0.02 respectively). This study demonstrated that plyometric push-ups lead to performance enhancement of the bench press exercise at 70%1RM. The increases in performance were observed only in the first set following the CA, while a significant decrease of these variables was registered in P-Set2 and P-Set3.
Learning by outward and inward internationalization and the outward/inward innovativeness of firms in Poland
Authors: Szymura-Tyc Maja 
Published: April 2021

Abstract
Many studies raise the issue of relationships between internationalization and innovativeness, linking them with firms’ international competitiveness. However, very few of these studies focus on the influence of internationalization on innovativeness and regard the multifaceted nature of these two concepts. The study presented in this paper is based on a holistic approach to internationalization and innovativeness. It explores the influence of the outward (e.g. exporting, outward FDI) and inward (e.g. importing, inward FDI) internationalization on the outward (product and marketing) and inward (process and organizational) innovativeness of 274 firms in Poland, adopting formative variables and a correlations analysis. The key contribution of the research is that the outward internationalization is conducive to both the outward and inward innovativeness, while the inward internationalization supports only the inward innovativeness. It shows that learning by outward and inward internationalization supports innovativeness of firms, responsible for their international competitiveness. The findings might be unique for transition and emerging economies characterized with a low degree of internationalization and innovativeness, while the holistic approach is more universal, and might bring interesting results when applied to the research of highly advanced economies.
Trend Analysis of Temperature and Humidity in Kwara State, Nigeria
Authors: Adedapo Adeniyi 
Published: April 2021

Abstract
This paper examines the trend analysis of temperature and relative humidity in Kwara State. Climatic data on annual mean temperature (minimum and maximum) and relative humidity for 40 years (1978-2017) were collected from Nigerian Meteorological Agency (NIMET) Ilorin. Semi-Average method, Mann- Kendull statistics and regression method were used to analyse the trend in temperature and relative humidity. The Standardized Anomaly Index (SAI) was also used to examine the changes in temperature and humidity over the period of 1978-2017. The result of the analysis indicates that temperature (minimum and maximum) and relative humidity exhibit an upward trend. This implies that temperature and relative humidity increase over the period of 1978-2017. The Mann-Kendull statistics values show that there is no significant difference in the values of temperature (minimum and maximum) and relative humidity. The result of the Standardized Anomaly Index (SAI) also revealed that the values of temperature and humidity fluctuated around the long –term mean. About 50% of the annual average relative humidity falls above the long term average while 40% of the annual mean maximum temperature falls above the long term average. It can therefore, be deduced that there is the possibility of increment in the values of temperature and relative humidity which could cause a serious challenge to human health and climate change. The study therefore, suggests that increase and fluctuations in temperature and relative humidity should be a critical factor in designing strategies to mitigate the effect of climate change on the environment and human health.

Abstract
For efficient reservoir management and long-term field development strategies, most geologists and asset managers pay special attention to reservoir chance of success. To minimise this uncertainty, a good understanding of reservoir presence and adequacy is required for better ranking of infill opportunities and optimal well placement. This can be quite challenging due to insufficient data and complexities that are typically associated with areas with compounded tectonostratigraphic framework. For the present paper, data analysis and variography were used firstly to examine possible geological factors that determine directions in which reservoirs show minimum heterogeneity for both discrete and continuous properties; secondly, to determine the maximum range and degree of variability of key reservoir petro-physical properties from the variogram, and thirdly, to highlight possible geological controls on reservoir distribution trends as well as areas with optimal reservoir quality. Discrete properties evaluated were lithology and genetic units, while continuous properties examined were porosity and net-to-gross (NtG). From the variogram analysis, the sandy lithology shows minimum heterogeneity in east-west (E–W) and north-south (N–S) directions, for Upper Shoreface Sands (USF) and Fluvial/Tidal Channel Sands (FCX/TCS), respectively. Porosity and NtG both show the least heterogeneity in the E–W axis for reservoirs belonging to both Upper Shoreface and Fluvial Channel environments with porosity showing a slightly higher range than NtG. The vertical ranges for both continuous properties did not show a clear trend. The Sequential Indicator Simulation (SIS) and Object modelling algorithm were used for modelling the discrete properties, while Sequential Gaussian Simulation (SGS) was used for modelling of the continuous properties. Results from this exercise show that depositional environment, sediment provenance, topographical slope, sub-regional structural trends, shoreline orientation and longshore currents, could have significant impacts on reservoir spatial distribution and property trends. This understanding could be applied in reservoir prediction and for generating stochastic estimates of petrophysical properties for nearby exploration assets of similar depositional environments.

Abstract
This study aims to examine the interaction effect of country of manufacture and brand awareness, packaging and price impact on the purchase intention of toothpaste among young adults in Malaysia. As previous studies show, the country of origin should not be taken as a single clue, as it exaggerates the country of origin effect. This study evaluates the effect of the country of origin effect on the low-involvement good (toothpaste). The Cue Utilization Theory was used to explain how the consumer uses product cues to rate a product before making a purchase decision. Study data are analysed using SmartPLS. The results of this study showed that all variables influence consumer purchase intention for toothpaste. IPMA analysis showed that the interaction effect of the country of manufacture and brand awareness are important factors.

Published: April 2021

Abstract
József Engel (1807–1870) originates from an intellectual family from the Northern part of Hungary, he got to Marosvásárhely (Târgu Mureş) due to family relations. There he was assistant in the Golden Deer Pharmacy. Later he graduated the theoretical course of Chemistry at the Pest University. His thesis was printed. Then he studied medicine at the same university between 1830 and 1836. He wrote his thesis about the measles (De Morbilis). Meanwhile studying at Pest he got interested in Hungarian linguistics. He elaborated a study on the stem words of the Hungarian language which won a competition of the Hungarian Academy of Science. Engel was a much appreciated general practitioner at Marosvásárhely. The famous mathematician, János Bolyai was also his patient. He subscribed to German medical journals, collected plants and minerals. But his major interest was linguistics. In the middle of the 1850-s there was a movement at Kolozsvár (Cluj-Napoca) to establish a Museum Society. Then Engel’s linguistic research work was rediscovered. Some articles were published about him and even a fragment of his work in progress got printed. In 1857 Engel moves to Kolozsvár to help the founding of the Transylvanian Museum Society and to finish his treatise. As a general practitioner he could hardly make his living. In 1859 the Hungarian Academy of Science elected him corresponding member. He finished his thesis in linguistics and sent it to the Academy as an inaugural address. It was presented, but not published. His conception was considered obsolete. He died quite forgotten at Kolozsvár. At the Academy Henrik Finály held a memorial speech upon his life and activity. His two sons and two grandsons continued the medical traditions.

Published: April 2021

Abstract
Chronic, non-communicable diseases are affecting the lives of more and more people worldwide; due to obesity and inadequate eating habits, the proportion of diabetics is on an increasing trend globally. The development of a number of macro- and microangiopathic pathologies associated with the onset of diabetes affects the life expectancy of patients. Diabetic foot infection (DFI) is one of the most serious long-term complications of diabetes and may be considered an intersection of infectious and non-infectious diseases; these infections can significantly reduce the quality of life of affected patients. The purpose of this review was to summarize the latest recommendations for conservative (non-surgical) therapy for DFIs and diabetic foot osteomyelitis (DFO).

Coping strategies as predictors of professional burnout in Polish nurses
Authors: Goś Anna , Szczekala Katarzyna , Humeniuk Ewa 
Published: April 2021

Abstract

Introduction. Professional burnout, as a defensive, psycho-physical reaction to chronic occupational stress resulting from the imbalance between the demands of the environment and resources of an individual, is the phenomenon which considerably affects the nursing profession. Coping strategies reflect typical ways of reacting to stressful events. The following dissertation is an attempt to provide information on which coping strategies predispose nurses to burnout.

Aim. The aim of the study is determination of coping strategies that are predictors of professional burnout in Polish nurses.

Material and methods. The research group comprised 29 nurses employed in hospitals located in Eastern Poland. The authors’ own socio-demographic questionnaire and standardised psychometric tools were utilised in the course of the research. Brief COPE by S.CH. Carver, adapted into Polish by Z. Juczyński and N. Ogińska-Bulik was applied to determine coping strategies. Link Burnout Questionnaire by M. Santinello, adapted into Polish by A. Jaworowska, was used to measure burnout.

Results. Psychophysical exhaustion is to a great extent connected with such coping strategies as self-blame and planning. Relationship deterioration affects individuals who tend to react to a stressful event by venting emotions. The greater the tendency to self-blame and venting when faced with a stress-related situation, the greater the risk of experiencing the sense of professional ineffectiveness. Disillusion with work is conditioned by denial whereas self-distraction protects from disillusion.

Conclusions. Polish nurses present a moderate and high level of burnout. Some coping strategies (self-blame, venting, self-distraction, planning and denial) are predictors of professional burnout in nurses. It can be assumed that interventions aimed at training certain coping strategies based on the research results may enhance resistance to burnout in nursing professionals.
The air quality health index and emergency department visits for injury
Authors: Szyszkowicz Mieczysław 
Published: April 2021

Abstract

Introduction. The purpose of this study was to investigate the associations of ambient air quality with emergency department (ED) visits for injury.

Aim. To explore correlations between ED visits for injury and ambient air pollution.

Materials and methods. Considered health outcomes are ED visits for injury (ICD-9 codes: 800-999) in Edmonton, Canada, for the period from April 1998 to March 2002 (1,444 days). Air pollution concentration in the ambient air is represented as a daily maximum of the Air Quality Health Index (AQHI). The AQHI value encapsulates levels of three urban ambient air pollutants (ozone, nitrogen dioxide and fine particulate matter), weighted by constant risk coefficients. A time-stratified casecrossover design, using conditional logistic regression and conditional Poisson regression, was realized to assess the associations. The risk, reported as odds ratio and relative risk, was estimated using log-linear models and parametric non-linear concentrationresponse functions.

Results. The strongest effects were observed for young male patients in the cold season (October-March). Lagged exposures were found to have positive statistically significant associations.

Discussion. The study results indicate that air quality was associated with increased risk of daily ED visits for injury. This study determined concentration-response functions which allow one to assess the effects for various levels of the AQHI.

Published: April 2021

Abstract

Introduction. Human skin is the outer cover of the body. It performs important functions for the entire organism, such as protection of internal organs. The skin also protects the body against the effects of the external environment, ensures the balance between the environment and the inside of organism. Due to the pandemic, all members of the public are encouraged to frequently wash or disinfect hands, which may lead to skin irritation.

Aim. The aim of the study was to check the pH of soaps, skin care products and selected cosmetics used in the period of COVID-19 pandemic.

Materials and methods. For pH determination the CP-105 pH meter manufactured by ELMETRON® (Poland) was used. A total of 111 products available on the Polish market were collected for testing. The results were compared with the pH of tap water samples.

Results. The soaps had mean pH of 5.04±1.04, shampoos 6.04±1.57, creams 6.87±0.1, products for depilation 9.8±3.06. All the values were within legal ranges.
Conclusion. The majority of skin and hair cosmetics have pH close to the pH of tap water. Chemical hair removal products have the most alkaline pH and therefore, require extreme caution as they can cause irritation.

Published: April 2021

Abstract

Introduction. The surgery and its circumstances are difficult situation for patient and his/her relatives. Patient is afraid of operation, itss consequences, hospitalization regardless of the type of surgery and course of anaesthesia. Obtaining reliable information by patient from the staff helps to understand the desirability of procedure and principles for preoperative preparation.

Aim. The assessment of the influence selected factors on the level of stress perceived by patients qualified for the anaesthesia before the operation.

Material and methods. A survey performed amongst 100 adult patients (women and men), qualified for anaesthesia prior to surgery in Independent Public Clinical Hospital No. 4 in Lublin (SPSK-4). Research tools – an authorial questionnaire composed of 19 questions and the scale of perceived stress PSS-10.

Discussion. Research has shown that level of stress before anaesthesia and surgery was significantly higher in group of women than men. Furthermore, respondents who work occupationally more frequently had high and very high level of stress compared to the surveyed with pension, retirement or unemployed. Age, place of living, education, marital status, material status, presence of intercurrent illness, type of operation/anaesthesia as well as number of procedures found no relationship regarding the level of perceived stress.

Conclusion. 1. The level of stress before anaesthesia for surgery is high. 2. Gender and professional activity affect the level of experienced stress. 3. The patient’s mental preparation may have an influence on perioperative stress reduction.

Published: April 2021

Abstract
In the first half of 2020, the global pandemic of the COVID-19 virus became a phenomenon affecting all spheres of human life. Measures against the spread of the virus have led to restrictions in life in public spaces and have also affected the transport sector. These impacts consisted of two types - firstly, the number of connections was reduced due to a drop in transport demand, and secondly, it was necessary to comply with hygiene measures on the part of carriers and passengers. The impacts of these measures could be monitored at all spatial levels, from global to local. This paper deals with the course of the so-called first wave of the pandemic in the Czech Republic in relation to public transport and its organization. The aim of the paper is to provide an overview of these measures in relation to general government regulations and their subsequent implementation at the national, regional (county) and local (selected large cities) level. Furthermore, the paper uses three case studies to show what changes long-distance domestic transport has undergone on selected routes. There was a significant reduction in the number of long-distance connections, some lines were not operated at all, and of course, all cross-border connections were canceled. The paper covers the period from the turn of February and March 2020, when the measures began to take effect, to the end of May 2020, when almost all the adopted measures were gradually relaxed. The paper concludes with a summary of the basic features of the organization of transport during the validity of the special measures, as well as areas where significant changes took place and whose consequences may persist after the pandemic subsides.
