1. A comparative study using two SEM techniques on different samples sizes for determining factors of older employeeʹs motivation and satisfactionMaja Rožman, Polona Tominc, Borut Milfelner, 2020, izvirni znanstveni članek Opis: The purpose of this article is to present the relationships among older employee stress, motivation, satisfaction, and relationships in the workplace using two different approaches and different sample sizes. Research was implemented on an initial sample of 1013 older employees. In the next step, six smaller samples were calculated using the random selection of cases, namely samples with 25, 50, 100, 250, 400, and 500 older employees. This way the possible impact of sample size on relationships between latent variables using the covariance-based structural equation modeling (CB-SEM) and the partial least squares structural equation modeling (PLS-SEM) methods was assessed. The results on the larger samples have proved to be quite robust since they were confirmed with both approaches. They indicate that stress has a strong and negative impact on employee relationships and also a negative impact on employee satisfaction. Furthermore, employee relationships have a strong and positive impact on satisfaction and a positive impact on employee motivation. In addition, satisfaction has a strong and positive impact on employee motivation. The present paper helps readers to better understand the difference between the CB-SEM and the PLS-SEM methods. Researchers should be encouraged to use both techniques, even though CB-SEM methods have had a long tradition in management and marketing research since both fields heavily rely on psychometric measurement. From the organizational point of view, conclusions highlight the importance of the impact the variables of older employee stress, motivation, satisfaction and employee relations have on each other in the workplace.

2. A comprehensive approach in medical nutrition therapy for adults' weight loss management in LebanonMarie Therese Khalil, Joseph Matta, Mateja Videmšek, Damir Karpljuk, Maja Meško, 2020, izvirni znanstveni članek Opis: The objective of the research is to identify the different factors of Lebanese culture that interfere with weight loss therapy and assist the field of nutrition in homogenising in a standardised manner the protocol of Medical Nutrition Therapy (MNT). The first part of the study is based on a literature review, and, in the second part, quantitative analysis was used. The research was conducted on 514 Lebanese adults via questionnaire. The analysis was performed with the AMOS (Version 22, IBM®, Amonk, NY, USA) statistical tool. For the analysis of correlations, chi-square and non-parametric tests were used. Variables affecting weight loss management were identified with the aid of seven hypotheses using structural equation modelling (SEM). Body shape and Body Mass Index (BMI) were found to be inter-related to cognitive behaviours toward food, lifestyle practices, medical conditions, food and beverages. In parallel, and based on the research results, younger adults, in particular women, have better BMI and look better in terms of body shape. Ageing has a direct impact on weight gain. Older people have a lower activity level, which is more prevalent among women, and they also prefer to eat typical Lebanese food. Habits, such as smoking, drinking alcohol, are directly related to obesity and some medical conditions. Low physical activity influences the problems related to body shape. For further studies, one should also include types of physical activities in terms of intensity and number of hours. This would assist the study in being more specified and credible toward the effect of exercise on weight loss management.

3. Quality of life and health status in middle-aged presumed healthy Slovenian family practice attendeesMatic Tement, Polona Selič-Zupančič, 2021, izvirni znanstveni članek Opis: Background: There is a gap in our knowledge of health-related quality of life (HRQoL) in a population presumed healthy, so this study aimed to assess the associations between HRQoL, demographics and clinical variables.
Methods: The participants were attendees, presumed healthy, at 40 pre-selected model family medicine practices (MFMPs), aged between 30 and 65 years and recruited during a preventive check-up in 2019. Each MFMP pragmatically invited 30 attendees to voluntarily participate. The EQ-5D questionnaire was administered as a measure of HRQoL; the independent variables were demographic characteristics, smoking, alcohol consumption, stress perception, physical activity, signs of depression, cardiovascular risk, body mass index, blood pressure values, and blood sugar and lipidogram laboratory test values. Ordinal logistic regression was used to calculate associations between self-assessed quality of life, demographics, and clinical variables, with P<0.05 set as statistically significant.
Results: Of 986 participants, 640 (64.9%) were women and 346 (35.1%) men, aged 42.7+-8.6 years. The average values for the EQ-5D-3L were 0.9+1-0.15. In the multivariate model, a positive association between adequate physical activity (p=0.003), and a negative association between higher age (p<0.001), female gender (p=0.009), signs of depression (p<0.001), stress (p=0.013), and EQ-5D score were identified.
Conclusion: Given that physical activity was shown to be positively associated with HRQoL, it is of the utmost importance for family physicians to motivate their middle-aged patients, especially women and those with signs of depression and excessive stress, to adopt a more rigorously physically active lifestyle.

4. Building organisational sustainability during the COVID-19 pandemic with an inspiring work environmentMaja Rožman, Anita Radman Peša, Mladen Rajko, Tjaša Štrukelj, 2021, izvirni znanstveni članek Opis: This article aims to analyse significant differences in four constructs: occupational stress, job satisfaction, work engagement, and work productivity among employees before and after the COVID-19 pandemic. The purpose of the paper is to develop a multidimensional model with these four constructs and analyse the differences in the strength of their effects on the model across two intersectional times: before the COVID-19 pandemic and during the COVID-19 pandemic. The research was implemented on a sample of 885 employees in Slovenian organisations. During COVID-19, Slovenia had one of the strictest lockdowns. Based on the research, we can confirm significant differences in the four analysed constructs among employees before COVID-19 and during COVID-19. Based on the results, we can confirm that occupational stress had a more negative effect on job satisfaction and work engagement during COVID-19 than before prior to it. Our research and conclusions highlight the measures with which organisations can reduce the problem of occupational stress and with which organisations can increase job satisfaction, work engagement and work productivity among employees during COVID-19. Based on this, organisations may be able to build a more supportive work environment during, and after, COVID-19.

5. Effect of residual stresses on the fatigue stress range of a pre-deformed stainless steel AISI 316L exposed to combined loadingDarko Jagarinec, Nenad Gubeljak, 2024, izvirni znanstveni članek Opis: AISI 316L austenitic stainless steel is utilized in various processing industries, due to its abrasion resistance, corrosion resistance, and excellent properties over a wide temperature range. The physical and mechanical properties of a material change during the manufacturing process and plastic deformation, e.g., bending. During the combined tensile and bending loading of a structural component, the stress state changes due to the residual stresses and the loading range. To characterize the component’s stress state, the billet was bent to induce residual stress, but a phase transformation to martensite also occurred. The bent billet was subjected to combined tensile–bending and fatigue loading. The experimentally measured the load vs. displacement of the bent billet was compared with the numerical simulations. The results showed that during fatigue loading of the bent billet, both the initial stress state at the critical point and the stress state during the dynamic loading itself must be considered. Analysis was demonstrated only for one single critical point on the surface of the bent billet. The residual stresses due to the phase transformation of austenite to martensite affected the range and ratio of stress. The model for the stress–strain behaviour of the material was established by comparing the experimentally and numerically obtained load vs. displacement curves. Based on the description of the stress–strain behaviour of the pre-deformed material, guidelines have been provided for reducing residual tensile stresses in pre-deformed structural components.

6. Model of socially responsible transfer of parent organization culture to the subsidiary organization in a foreign cultural environment concerning internal communication, stress, and work satisfactionDarja Kukovec, Borut Milfelner, Matjaž Mulej, Simona Šarotar Žižek, 2021, izvirni znanstveni članek Opis: The organizational culture is a significant construct in a time of change during the organizational transition, and it plays an important role in achieving goals of social responsibilities, which is an important part of sustainability. The literature shows the gap of socially responsible transfer of organizational culture with the impact on employee’s well-being. The cultural changes of the organization during the transition are particularly in connection with the impact on internal communication where organizational culture presents a part of values, norms, and ethics, which influences successfully implemented changes and in such a way has an influence on the stress and work satisfaction. The main purpose of the presented study is the development of the model of socially responsible transfer of organizational culture to the foreign subsidiaries on a basis of adjusted internal communication, which reduces stress and increases work satisfaction. Impacts of organizational culture on internal communication, stress, and work satisfaction are clearly presented, as well as inter-related impacts of the constructs concerning national culture, leadership, and organizational knowledge. Thus, the new holistic model of socially responsible transfer of the parent organization culture to foreign subsidiaries clearly defines steps of organizational culture, internal communication, stress management, and work satisfaction. Managerial implications are discussed.

7. Personalizing human–robot workplace parameters in human-centered manufacturingRobert Ojsteršek, Borut Buchmeister, Aljaž Javernik, 2024, izvirni znanstveni članek Opis: This study investigates the relationship between collaborative robot (CR) parameters and worker utilization and system performance in human–robot collaboration (HRC) environments. We investigated whether optimized parameters increase workplace efficiency and whether adapting these parameters to the individual worker improves workplace outcomes. Three experimental scenarios with different CR parameters were analyzed in terms of the setup time, assembly time, finished products, work in process, and worker utilization. The main results show that personalized CR parameters significantly improve efficiency and productivity. The scenario in which CR parameters were tailored to individual workers, balanced the workload, and minimized worker stress, resulting in higher productivity compared to non-people-centric settings. The study shows that personalization reduces cognitive and physical stress, promotes worker well-being, and is consistent with the principles of human-centered manufacturing. Overall, our research supports the adoption of personalized, collaborative workplace parameters, supported by the mathematical model, to optimize employee efficiency and health, contributing to human-centered and efficient HRC environments.

8. Acute kidney injury after open-heart surgery proceduresAnže Djordjević, Stamenko Šušak, Lazar Velicki, Miha Antonič, 2021, pregledni znanstveni članek Opis: Cardiac surgery-associated acute kidney injury (CS-AKI) is a major complication associated with increased morbidity and mortality. There are multiple diagnostic criteria for CS-AKI. Despite many new investigations available for improved AKI diagnostics, creatinine and urea remain the cornerstone of diagnostics in everyday clinical practice. There are three major pathophysiological mechanisms that contribute to kidney injury, i.e. renal hypoperfusion, inflammation with oxidative stress, and use of nephrotoxic agents. Some risk factors have been identified that can be modified during the course of treatment (use of nephrotoxic agents, duration of cardiopulmonary bypass, type of extracorporeal circulation, postoperative low cardiac output or hypotension). The aim of AKI prevention should always be to prevent aggravation of renal failure and, if possible, to avoid progression to renal replacement therapy, which in turn brings worse long-term outcomes.

9. Growth and glucosinolate profiles of Eruca sativa (Mill.) (rocket salad) and Diplotaxis tenuifolia (L.) DC. under different LED lighting regimesDenis Stajnko, Peter Berk, Andrej Orgulan, Marko Gomboc, Damijan Kelc, Jurij Rakun, 2022, izvirni znanstveni članek Opis: In this study, the growth and glucosinolate (GSL) profiles of rocket salad Eruca sativa (Mill.) and Diplotaxis tenuifolia (L.) DC. were determined during 30 days growing under different lighting regimes; T5_ peak at 545 nm, LED1_ peak at 631 nm and LED2_ peak at 598 nm. The biggest increase of dry weight (DW) was measured in E. sativa under T5 (0.657 g DW/plant) and the lowest in D. tenuifolia under LED1 (0.080 g DW/plant). GSL content was found to vary significantly, regardless of the light treatment, but it is related with genotype (E. sativa, r = 0.802**). On average, the highest amount of 4-methylsulfinylbutyl-GSL (glucosativin) (7.3248 mg/g DW) was quantified in E. sativa and D. tenuifolia (6.7428 mg/g DW) under the T5. The regression analysis between different light wavelengths and glucosinolates showed the strongest correlation between photosynthetic photon flux density (PPFD_B) and 4-methylthiobutyl-GSL (glucoerucin) in E. sativa (r = 0.698*) and D. tenuifolia (r = 0.693*), respectively, which indicates the effect of light on the response of plants to induced stress and changes in GSL biosynthesis.

10. Exploring the feelings of nurses during resuscitation : a cross-sectional studyAnton Koželj, Maja Šikić Pogačar, Sabina Fijan, Maja Strauss, Vita Poštuvan, Matej Strnad, 2022, izvirni znanstveni članek Opis: Cardiopulmonary resuscitation (CPR) is one of the most stressful situations in emergency medicine. Nurses involved in performing basic and advanced resuscitation procedures are therefore exposed to a certain amount of stress. The purpose of this study was to determine the stressors and the level of stress experienced by nurses during resuscitation. A cross-sectional quantitative study was done. The sample consisted of 457 nurses who worked in emergency units. First demographic data were collected, followed by a questionnaire regarding the effect of different situations that occur during and after resuscitation on nurses including Post-Code Stress Scale questionnaire. The most disturbing situations for respondents were resuscitation of young person (MV = 3.7, SD = 1.4), when they fail to establish an intravenous pathway (MV = 3.5, SD = 1.4), chaotic situation during resuscitation (MV = 3.4, SD = 1.4) and making decision about termination of resuscitation (MV = 3.1, SD = 1.5). Research has shown that nurses are exposed to a certain amount of stress during resuscitation, but most of them manage to compensate for stress effectively.
