Purpose: Since reward and incentive programs play a key role in attracting new employees and motivating existing ones, we decided to investigate which programs are used by highly desirable employers ...and how satisfied their employees are with these programs.Methodology: A survey on employee satisfaction with work and reward and incentive programs was conducted among 160 (10%) employees of the company dm-drogerie markt d.o.o. The obtained data were processed using methods of descriptive statistics and non-parametric tests.Results: The average satisfaction of employees with the reward and incentive system is 4.39 on a scale from 1 to 5, where 5 means “completely satisfied”. The average job satisfaction is 4.47, and a moderate positive correlation was found between job satisfaction and satisfaction with the reward and incentive system (rs=0.523, p<0.010). Differences in the level of satisfaction were found in relation to the department and salary level of the respondents: more satisfaction was expressed by employees in the Sales Region department and by those in the highest salary level.Conclusion: The analysis revealed a high average satisfaction level, but also a gap between the importance that employees attach to a particular program and their satisfaction with that program. The results confirm the importance of the reward and incentive system for overall job satisfaction and can be used to improve this system within the company.

This study investigates the mechanical behavior of femur bones under loading conditions, focusing on the transition from elastic to plastic deformation and eventual fracture. The force–displacement ...curves reveal distinct phases of deformation, with an initial linear relationship indicating elastic behavior, followed by deviation from linearity marking the onset of plastic deformation. Fracture occurs beyond a critical load, leading to a sharp drop in the force–displacement curve. The maximum fracture force varies among specimens and is influenced by bone geometry, size, cross-sectional area, and cortical thickness. Post-failure analysis highlights additional insights into fracture mechanics and bone material toughness. Reinforcing bones with screws enhances their strength, which is evident in the higher fracture forces observed in force–displacement diagrams. Fixation procedures following fractures further increase bone strength. Comparing specimens with and without strengthening underscores the effectiveness of reinforcement methods in improving bone mechanical properties. After analyzing the results, it is evident that femur bones with reinforcement can withstand greater loads, and they can also absorb higher impact energies while remaining in the elastic deformation range and without suffering permanent plastic damage. This study provides valuable insights into bone biomechanics and the efficacy of reinforcement techniques in enhancing bone strength and fracture resistance.
Steel bottles, most commonly used by scuba divers, are prone to rust and need to be maintained properly and preventively examined during usage. Due to the geometrical characteristics of the tank ...(rounded wall) and the inaccessible inner surface of the wall where corrosion damages and initial cracks are expected to be found, the conventional nondestructive techniques do not yield usable results. Herein, emphasis is placed on non-destructive testing (NDT) by means of infrared thermography. The Pulse Phase Thermography (PPT) has been used for composite polymer matrix materials, but with the development of IR cameras, the method has found its application even for NDT of thin metal plates. In this paper, the Fast Fourier Transform (FFT) of infrared images is applied on severely corroded scuba divers tank. The amplitude and phase images contain information on damages or/and other structures inside the inspected part as these lead to a shift in the amplitude and phase of heat waves. In damaged areas heat wave passes shorter path due to differences in the thickness of the metal wall resulting in different heating/cooling curves. As a result, heat waves have different phase delay and defects can be seen as different color zones on phase images in characteristic pit corrosion oval shape.
Heat generation during the dynamic loading and plastic flow process in material is the basic of theory of plasticity. The infrared thermography based on the middle wave camera provides tracking the ...thermal phenomena in material associated with the plastic flow during the dynamic loads process. The temperature gradient has been applied to track the heat propagation direction and consequently plastic flow in materials and structures. Closed cell aluminum metal foam, foamed within a structural member, is evaluated as an energy absorber. The thermographic approach enabled to trace and evaluate energy absorption performances of hollow structural members with metal foam filler material.
Composite materials, such as glass and carbon reinforced ones, are characterized by inhomogeneous structure that requires non destructive testing based on uncommon evaluation methods. The presented ...approach is based on the active infrared thermography, supported by the A-scan ultrasound testing. The heat wave propagation induced by halogen or xenon bulbs, due to the differences in thermal conductivity, reveals material structure and anomalies. In our previous work we have developed several signal processing and depth evaluation methods, but the real engineering approach requires additional approval testing methods such as the A-scan ultrasound is. The A-scan ultrasound, based on the low frequency probe, enables approval of anomalies located by infrared thermography. The active infrared thermography, as a full field method, enables evaluation of the whole scanned area. The A-scan, as a point-wise method, does not provide the image of whole area of interest. By combining these two methods, robust and reliable approach to analysis of composite structure is enabled.
