Abstract:

The development of technology and changes in the world have dramatically increased the psycho-emotional risk exposure for office employees. At the work with computer and digital devices in the offices, employees are exposed to several risk factors of the work environment and one of the most frequent complaints is psycho-emotional load caused by various issues. There is no denying that sleep is one of the basic human needs, and sleep quality is important for maintaining and preserving good health and wellbeing. Sleep hygiene includes a set of various measures, such as the regularity of waking up and going to bed, that can affect and improve the quality of sleep. Sleep quality is closely related to mental health, as poor mental health can negatively affect sleep quality and vice versa. Reduced psycho-emotional load is associated with better sleep hygiene and also good sleep hygiene is associated with reduced psycho-emotional load. Health promotion measures and a work environment that supports sleep health could reduce psycho-emotional load experienced by employees, increase work ability, productivity and reduce the risk of accidents at the workplace. The aim of this study was to investigate psycho-emotional load and sleep hygiene importance for office employees.

Key words:

office employees, psycho-emotional load, sleep hygiene, stress., work ability

Abstract:

In this study, relation between employee organizational identification, employee burnout and mental well-being was explored. The main aim of this research was to investigate, whether higher level of organizational identification cause employee burnout, jeopardizing mental well-being. An online survey was created using Qualtrics and participants were recruited via Facebook and LinkedIn in May-July 2022 to measure organizational identification, burnout and mental well-being of employed people (n = 138). Results reveil that even if there is a risk of burnout, mental well-being and organizational identification are quite high. Therefore, mental well-being is not being jeopardized.

Key words:

burnout, mental well-being, organizational identification, stress.

Abstract:

The low temperature (LT) is detrimental to growth of rice seedling during boro season in Bangladesh. An experiment was conducted in growth chamber during June to October, 2021 using BRRI dhan29 as planting material. The aim of this experiment was to determine the effect of variable duration of LT on growth, physiological and biochemical traits of rice seedling and to determine the age of seedling that can tolerate cold effect. In this experiment 5, 10, 15 and 20 days old seedling (DOS) were exposed to 6 °C for 1, 2, 3 and 4 days. Seedlings were also grown under room temperature (25 °C, RT) which consider as control treatment. Seedlings were grown in plastic trays filled with mixture of soil and cowdung. The experiment was conducted following completely randomized design with 3 replications. Data on shoot length and weight, root length and weight, chlorophyll (Chl), carotenoids, malondialdehyde (MDA) and proline contain were determined after 5 days of temperature sock. The results revealed that the LT was injurious to younger rice seedling when they were exposed to LT for 1 to 2 days. The shoot and root length as well as their dry weight were reduced under low temperature. Further, the Chl and carotenoid content of younger rice seedlings degraded within 2 days of LT exposure. On the contrary, the proline and MDA content of rice seedlings increased to reduce the harmful effect of under LT. It could be concluded that the rice seedlings could tolerate the detrimental effect of LT when they attain at least 15 days.

Abstract:

Machine construction is designed using by mathematical models. The frame is a fundamental part of an agricultural soil cultivation machine so that forces were transferred during transport and machine work to frame. The stress in the machine frame is important to know for the best frame design of the machine. The mathematical model included measured strain can able to design or detect deficiencies on the machine frame. Due to the transfer of forces from the tools, stress is created in the machine frame. High requirements are placed on the determination of boundary conditions for mathematical models in agricultural machinery. Various types, sizes and equipment of agricultural tools significantly affect the transfer of drought force to the machine. The direction and magnitude of the forces, that are caused by agricultural tools, it is important to find out. Ansys mechanical solver have been used to determination strain like response of frame from chisel module. The results can be used as a boundary condition for mathematical models.

Key words:

agricultural machine, mathematical model, simulation., stress.

Abstract:

This study is focused on the utilization of the reciprocal slope transformation method (RST) and tangent curve method (TCM) for description of mechanical behaviour of Jatropha bulk seeds under compression loading. The experimental data derived from a compression test was done using compression device and pressing vessel with diameter 60 mm at compression speed of 1 mm s−1 and compressive force between 0 kN and 100 kN. Measured dependency between compressive force and deformation was fitted by RST method and TCM method and they were statistically analysed by ANOVA. Comparison of both methods in individual pressing regions is an integral part of this manuscript. It was determined that reciprocal slope transformation method describes precisely the beginning of deformation characteristics and it can cover the reorganizing process in the bulk seeds. From the conducted study it also follows that tangent curve method is suitable for description of mechanical behaviour at bulk deformations in which the reorganization process in the bulk seeds is finished yet.

Abstract:

Aim of the study was to measure telework usage and to explore interactions between health, workload and telework. Telework is work that is carried out outside the central office, involving new technology that permits communication. Work carried out at any time, at any place, has been very common in the case of research institutes and universities. This type of work has advantages and disadvantages for both an employee and employer. The study of telework was carried out in Tallinn University of Technology (TUT) where working at home has been very common for a long time. The questionnaires were sent to academic personnel. The study shows that academic employees preferred teleworking for better concentration on work and saving time and money. There was no significant difference in telework usage by age and teleworkers had fewer complaints about tired eyes, arterial hypertension and stress.

Key words:

diseases, stress., telework, work hours
