The physical and mental health of citizens living in a country that encouraged face masks (China) and discouraged face masks (Poland) during the initial stage of the COVID-19 pandemic remained ...unknown. We conducted a cross-country study to compare the psychological impact of the COVID-19 pandemic on Poles and Chinese. This study aimed to compare the levels of psychological impact of pandemic and levels of anxiety and depression between China and Poland.
The survey collected information on demographic data, physical symptoms, contact history, and precautionary measures. The psychological impact was assessed using the Impact of Event Scale-Revised (IES-R), and mental health status was assessed by the Depression, Anxiety and Stress Scale (DASS-21). The chi-squared test was used to analyze the differences in categorical variables between the two populations. Linear regression was used to calculate the bivariate associations between independents variables (e.g., physical symptoms and precautionary measures) and dependent variables (e.g., mental health outcomes).
This study included a total of 2,266 respondents from both countries (1,056 Poles and 1,210 Chinese). There were significantly less Polish respondents who wore face masks (Poles: 35.0%; Chinese: 96.8% p < 0.001). Significantly more Polish respondents reported physical symptoms resembling COVID-19 infection (p < 0.001), recent medical consultation (p < 0.01), recent COVID-19 testing (p < 0.001), and hospitalization (p < 0.01). Furthermore, Polish respondents had significantly higher levels of anxiety, depression and stress (p < 0.001) than Chinese. The mean IES-R scores of Poland and China were above the cut-off for post-traumatic stress disorder (PTSD) symptoms. Besides precautionary measures, unemployment, retirement, physical symptoms resembling COVID-19 infection, recent medical consultation or COVID-19 testing, and long daily duration of home confinement were risk factors for PTSD symptoms, anxiety, depression, or stress for Polish respondents.
Use of face masks at the community level may safeguard better physical and mental health during the COVID-19 pandemic. There is a need of health education with scientific information from Polish health authority on the proper use of face masks and reduce social stigma. This study was limited by the respondent sampling method that had compromised the representativeness of samples.
Most studies on motivation to work concentrate on its environmental and situational antecedents. Individual values are not the point of interest of empirical analyses. The aim of the research ...described in the paper was to seek possible relationships between work ethic and motivation to work. A hypothesis was put forward that work ethic, in the classical Weberian approach, is connected with motivation to work, from the point of view of Ryan's and Deci's self-determination theory. The study on a sample of 405 Polish employees was conducted with use of the Polish version of Multidimensional Work Ethic Profile MWEP-PL and Work Extrinsic and Intrinsic Motivation Scale, in the Polish adaptation WEIMS-PL. The Canonical Correlation Analysis was used to assess the simultaneous interrelationships between two sets of the variables measured. The results show that selected dimensions of work ethic, such as centrality of work, valuing hard work, perceiving work as an obligation, anti-leisure sentiment and delay of gratification are positively related to autonomous dimensions of motivation: intrinsic motivation, integration and identification, and non-autonomous introjection. Attributing a high value to hard work, including the conviction that it leads to success, aversion to wasting time and self-reliance correlate positively with taking up work for extrinsic rewards and with the desire to acquire a positive opinion about oneself as well as gain approval and recognition from others. Work ethic is connected on the one hand with autonomous motivation, including in particular intrinsic motivation, and on the other hand with extrinsic motivation, with the striving for success, which is the result of work. After empirical verification the findings could become a base for training programs and shape the way of influencing people's motivation, morale, attitude towards work and job satisfaction. They can result in the way employees are managed and selected for different tasks.

Ukraine has been embroiled in an increasing war since February 2022. In addition to Ukrainians, the Russo-Ukraine war has affected Poles due to the refugee crisis and the Taiwanese, who are facing a ...potential crisis with China. We examined the mental health status and associated factors in Ukraine, Poland, and Taiwan. The data will be used for future reference as the war is still ongoing. From March 8 to April 26, 2022, we conducted an online survey using snowball sampling techniques in Ukraine, Poland, and Taiwan. Depression, anxiety, and stress were measured using the Depression, Anxiety, and Stress (DASS)-21 item scale; post-traumatic stress symptoms by the Impact of Event Scale-Revised (IES-R) and coping strategies by the Coping Orientation to Problems Experienced Inventory (Brief-COPE). We used multivariate linear regression to identify factors significantly associated with DASS-21 and IES-R scores. There were 1626 participants (Poland: 1053; Ukraine: 385; Taiwan: 188) in this study. Ukrainian participants reported significantly higher DASS-21 (p < 0.001) and IES-R (p < 0.01) scores than Poles and Taiwanese. Although Taiwanese participants were not directly involved in the war, their mean IES-R scores (40.37 ± 16.86) were only slightly lower than Ukrainian participants (41.36 ± 14.94). Taiwanese reported significantly higher avoidance scores (1.60 ± 0.47) than the Polish (0.87 ± 0.53) and Ukrainian (0.91 ± 0.5) participants (p < 0.001). More than half of the Taiwanese (54.3%) and Polish (80.3%) participants were distressed by the war scenes in the media. More than half (52.5%) of the Ukrainian participants would not seek psychological help despite a significantly higher prevalence of psychological distress. Multivariate linear regression analyses found that female gender, Ukrainian and Polish citizenship, household size, self-rating health status, past psychiatric history, and avoidance coping were significantly associated with higher DASS-21 and IES-R scores after adjustment of other variables (p < 0.05). We have identified mental health sequelae in Ukrainian, Poles, and Taiwanese with the ongoing Russo-Ukraine war. Risk factors associated with developing depression, anxiety, stress, and post-traumatic stress symptoms include female gender, self-rating health status, past psychiatric history, and avoidance coping. Early resolution of the conflict, online mental health interventions, delivery of psychotropic medications, and distraction techniques may help to improve the mental health of people who stay inside and outside Ukraine.

The aim of the present study was to explore whether remote and on-site work stress during the COVID-19 pandemic was experienced with different severity. The second goal was to investigate stress ...conditions at both working modes.
The study involved 946 individuals working in the education system and BSS sector in different Polish organizations. The following tools were used: the
by Dudek and Hauk, the Polish version of the scales to measure work-family conflicts by Grzywacz, Frone, Brewer and Kovner, Meyer and
in the Polish adaptation by Bańka, Wołowska and Bazińska, the
by Zalewska.
The analysis of intergroup differences revealed that remote work stress severity was significantly lower than on-site work stress severity. The regression analyses proved that work-family conflict and job satisfaction were significant predictors of remote and on-site work stress. Continuance commitment positively predicted on-site work stress. Both models turned out to be statistically significant. The variables included in the models explained 39% and 35% of the variability of the remote work and on-site work stress, respectively.
Remote work is associated with lower stress severity than on-site work. For both types of work, the higher the level of work-family conflict, the higher the level of stress severity, but the higher the job satisfaction, the lower the stress severity. Continuance commitment is positively related to on-site stress, which means that people who work for an organization and see no alternative feel more stressed. Such an effect was observed only in the case of on-site work. The study findings are discussed in light of previous research, and implications for organizational practice are considered.

The objective of the research was to investigate the efficiency of selected methods of data fusion from visual sensors used on-board satellites for attitude measurements. Data from a sun sensor, an ...earth sensor, and a star tracker were fused, and selected methods were applied to calculate satellite attitude. First, a direct numerical solution, a numerical and analytical solution of the Wahba problem, and the TRIAD method for attitude calculation were compared used for integrating data produced by a sun sensor and an earth sensor. Next, attitude data from the star tracker and earth/sun sensors were integrated using two methods: weighted average and Kalman filter. All algorithms were coded in the MATLAB environment and tested using simulation models of visual sensors. The results of simulations may be used as an indication for the best data fusion in real satellite systems. The algorithms developed may be extended to incorporate other attitude sensors like inertial and/or GNSS to form a complete satellite attitude system.
The aim of the paper is to present the findings from a study of the relationships between perception of worklife areas and trust in supervisor and interpersonal trust on the one hand, and assessment ...of the severity of stress at work on the other hand.
The study involved 1113 individuals working in different Polish organizations. The
(PSS-10) was used to measure stress severity. Assessments of worklife areas were measured using the
, while trust was measured using the
and the
, a tool for measuring trust in co-workers.
The regression analysis results prove that stress severity depends to the largest extent on the assessment of worklife areas (workload, reward, and values), as well as trust in the skills and competencies of the supervisor and trust in co-workers, based on cognitive factors. The role of trust in the supervisor, emphasizing the latter's benevolence and the belief in their integrity and of trust in co-workers, based on emotions, and the relationships of these variables with stress require clarification. The model turned out to be statistically significant, the variables included in the model explain 45% of the variability of the dependent variable.
Assessment of worklife areas is more significant for stress level prediction than the trust dimensions studied. Conclusions concerning the relationships between trust and stress must be cautious, and the matter should be studied further. Int J Occup Med Environ Health. 2022;35(6):719-30.

The aim of the study was to examine the potential differences in the assessment of the severity of work-related stress, and in the global assessment of the areas of worklife and individual worklife ...dimensions in employees working in service occupations.
The research covered 61 emergency workers, 92 helping professionals, and 58 knowledge workers. A subjective assessment of the areas of worklife was carried out using the
, and the
(PSS-10) was used to investigate stress severity.
The research has revealed statistically significant differences between workers belonging to the 3 groups of service occupations in their assessment of the severity of work-related stress. The findings have shown that 26% of the variance of the
variable is explained by belonging to a specific occupational group. Police officers and helping professionals experience comparably severe stress, which is significantly stronger than that experienced by the laboratory staff. Statistically significant differences have also been found between the studied groups in terms of the global assessment of all areas of worklife, as well as in the assessment of particular areas, i.e., control, rewards, fairness and values. No significant differences have been found with regard to the workload and community areas.
Working in social service occupations, whether as emergency or helping professionals, may lead to a similar level of stress severity. The surveyed workers do not differ in their assessment of workload or of the sense of trust, cooperation and support received from their co-workers. Further research should be carried out to explore the sources of stress, which may be linked to other factors than the areas of worklife presented here, such as stress inducing contact with customers, environmental determinants of work, existing hazards to life or health, or the intrinsic predispositions of individuals performing specific types of work and gender.

Background: The 2022 War in Ukraine has significantly affected the psychological well-being and daily lives of people in many countries.
Objective: Two aims of this transnational study were (1) to ...compare psychological distress and coping strategies among people living in Ukraine, Poland, and Taiwan, (2) to examine whether the associations between various coping strategies (ie. problem-focused coping, emotion-focused coping, and avoidance) and psychological distress (ie. depression, anxiety, stress, posttraumatic stress disorder symptoms, and hopelessness about the ongoing war) differed among people of various countries during the initial stage of the 2022 War in Ukraine.
Method: In total, 1,598 participants (362 from Ukraine, 1,051 from Poland, and 185 from Taiwan) were recruited using an online advertisement to complete online survey questionnaires, including the Brief Coping Orientation to Problems Experienced inventory; the 21-item Depression, Anxiety and Stress Scale; the Impact of Event Scale-Revised; and a questionnaire devised to assess the level of hopelessness about the ongoing war.
Results: Psychological distress and adoption of coping strategies differed across people of various countries. Among Taiwanese and Polish respondents, avoidant coping strategies were most strongly associated with all categories of psychological distress compared with problem- and emotion-focused coping strategies. However, the associations of various coping strategies with psychological distress differed to a less extent among Ukrainian respondents. In addition, problem- and emotion-focused coping strategies had comparable associations with psychological distress among the people of Ukraine, Poland, and Taiwan.
Conclusions: The 2022 War in Ukraine has affected the psychological well-being of people, especially the Ukrainians. Because of the strong association between the adoption of avoidance coping strategies and psychological distress, despite a less extent among Ukrainian respondents, adaptive coping strategies such as (problem- and emotion-focused) are suggested to help people during times of war.
The 2022 War in Ukraine affected the psychological well-being in Ukraine and elsewhere.
Compared with problem- and emotion-focused coping strategies, avoidant coping strategies had stronger association with psychological distress, but it varied among different cultures.

The following paper presents the key design and test activities associated with the development of POLON—a green microsatellite propulsion module using 98% Hydrogen Peroxide (HTP). POLON, which ...stands for “Polish Propulsion Module”, is the first step toward the development of a full, ready-to-be-commercialized satellite propulsion system at the Łukasiewicz—Institute of Aviation (Ł-IoA). The development of an entire microsatellite propulsion system within the frame of the POLON project effort is the natural milestone on the Ł-IoA green propulsion roadmap, which so far embodied research on fundamental HTP chemistry, work on elementary propulsion technologies, as well as the development of individual propulsion components. Within this article, POLON propulsion development logic is introduced first, and the major challenges associated with utilizing HTP for an orbital propulsion system are described. Consequently, the specific R&D activities aimed at mitigating the identified issues and risks are discussed. Those cover analytical as well as experimental work, including, but not limited to, HTP compatibility studies with candidate construction materials, waterhammer effect studies, HTP catalyst testing and evaluation, and propellant tank manufacturing studies. The initial results for those activities are presented and, finally, further development plans are discussed.
The article presents the mutual relations between the components of work ethic and the strategies of coping with stress used by employees of different branches.
Work ethic was presented as a syndrome ...of the following attitudes: perceiving work as a moral value, treating work as a central value in life, and the belief in the importance of hard work that leads to success. This ethic also consists of the following components: unwillingness to waste time, disapproval of spare time (anti-leisure), willingness to delay gratification, willingness to act honestly at work (morality/ethic), and being independent (self-reliance). Coping strategies were presented as 3 dimensions (obtained by application of factor analysis of the questionnaire scales COPE (Coping Orientations to Problems Experienced)): proactive cognitive operations, avoidance of action and seeking support.
The study conducted on 360 employees of different branches shows that the dimensions of the work ethic are moderately related to strategies emphasizing proactive cognitive operations and poorly related to seeking support and avoidance of action. At the same time, the relations between work ethic and avoidance of action are negative (higher work ethic is linked with lower tendency to avoid action).
Predictors of proactive cognitive operations are unwillingness to waste time, treating work as a central value in life, willingness to act honestly at work (morality/ethic) and being independent (self-reliance). Med Pr 2017;68(6):711-724.
