DIGITAL TRANSFORMATION IMPACT ON JOBS AFTER COVID-19 PANDEMIC

Digital transformation (DT) is a change in the business model of the company by applying new digital technologies. New digital technologies related to the application of automation, robotics, artificial intelligence and contemporary information and communication technology (ICT). The consequence of the application of DT will be the replacement of routine tasks with automation, which is controlled by artificial intelligence. Greater flexibility and efficiency of work will be achieved in terms of place of work, time of work and ways of engaging people. The changes will be felt by all companies, regardless of size or activity. Due to that, DT will also change the labour requirements. Automation of routine jobs will lead to large layoffs. Many professions will almost disappear as the technology they worked with becomes obsolete. It is envisaged to create new job profiles following the requirements of new technologies. Since the application of DT requires new skills and knowledge, it is necessary to educate workers and managers to successfully apply new technologies

Kontrola snage bazne stanice u GSM: utjecaj gustoće korisnika u stanici

In this paper is presented that base station output power can be decreased by the power control in each channel. In this case very important is the distribution function of users\u27 density in the cell. We present the examples of the cells without power control and the examples of the cells with power control, where the distribution of users\u27 density in the cell is of various types. Some results are compared to the results of measurements, and some to the results obtained by simulation.U radu se pokazuje da se izlazna snaga bazne stanice može smanjiti upravljanjem snage pojedinih kanala. U tom slučaju značajnu ulogu ima funkcija raspodjele gustoće korisnika u stanici. Dati su primjeri stanica bez upravljanja snagom i primjeri stanica s upravljanjem snagom gdje je raspodjela gustoće korisnika u stanici različitog tipa. Neki rezultati upoređeni su s rezultatima mjerenja, a neki sa simulacijskim rezultatima

ELECTRO-ACOUSTIC ANALOGIES BETWEEN THERMOELASTIC COMPONENT OF THE PHOTOACOUSTIC SIGNAL AND LOW-PASS RC FILTER

This paper presents a new approach to the thermal characterization of aluminum, based on the electro-acoustic analogy between the thermoelastic component of the photoacoustic signal and the passive RC low-pass filter. The analogies were used to calculate the characteristic thermoelastic cut-off frequencies of the photoacoustic component and obtain their relationship with the thickness of the aluminum samples. Detailed numerical analysis showed that the required relationship is linear in the log-log scale and can serve as a reference curve for the given material. The results of the numerical analysis were also confirmed experimentally

Metabolic Syndrome and C-reactive protein in patients with depressive disorder on antidepressive medication

Introduction Recurrent depression is a psychiatric disorder of which etiology and pathogenesis might be related to immune response. Metabolic Syndrome (MetS) and its components are also strongly associated with elevated inflammatory indicators, as so as the body mass index (BMI) and total cholesterol levels. Objective Objective of this study was to investigate if there was any difference in C-reactive protein (CRP) levels in patients with recurrent depressive disorder, treated with antidepressants, compared to a healthy control group of subjects and if there was an association between increased CRP levels and the presence of MetS in these two groups. Methods Sixty subjects entered the study; of these 35 patients with the diagnosis of recurrent depressive disorder, while the healthy control group included 25 subjects. MetS was defined according to the NCEP ATP III criteria. The cut-off point for CRP was set at >5 mg /L. Results There was no statistically significant difference in the prevalence of MetS and CRP values between the studied groups. Waist circumference and total cholesterol levels were significantly higher in the experimental group. Patients that fulfilled the criteria for MetS showed significantly higher values of central obesity and arterial hypertension in the experimental group as well. The elevated CRP levels were associated with increased frequency of MetS in depressed patients. Conclusion Both CRP levels and metabolic risk profile screening, according to the international criteria, may be beneficial in order to obtain better assessment for depressive long term medicated patients

Uticaj važnijih negenetskih faktora na fenotipsku varijabilnost osobina mlečnosti u populaciji crno belih goveda

Modern beef production in intensive rearing conditions imposes a need for constant improvement of production traits of individuals. Meeting the growing requirements that accompany this type of production means the provision of optimal rearing conditions, not only in terms of cattle nutrition, care and housing but also in terms of health. Milk yield, milk fat and protein are properties of primary importance in dairy cattle breeding. These properties express a pronounced variability that occurs due to a large number of factors. The paper presents the average values and phenotypic variability of major milk production traits in the black-and-white cattle population raised on the farm "PK Beograd". In the first three standard lactations the average milk yield was 7.241 kg with 3.56% fat. The impact of major non-genetic factors (farm, year, season of calving) on the expression of milk production traits was also observed. The impact of the examined factors on the variability of the production traits was highly significant (P <0.01).Savremena govedarska proizvodnja u intenzivnim uslovima odgajivanja nameće potrebu konstantnog unapređenja proizvodnih osobina jedinki. Realizacija sve većih zahteva koji prate ovu proizvodnju podrazumeva obezbeđenje optimalnih uslova gajenja, kako u pogledu ishrane, nege i smeštaja, tako i zdravstvenog stanja goveda. Prinosi mleka, mlečne masti i proteina su osobine od primarnog značaja u selekciji i oplemenjivanju mlečnih rasa goveda. Ove osobine pokazuju izraženu varijabilnost koja se javlja usled delovanja velikog broja činilaca na njihovu ispoljenost. U radu su prikazane prosečne vrednosti i fenotipska varijabilnost važnijih osobina mlečnosti u populaciji crno belih goveda gajenih na farmi PK “Beograd”. U prve tri standardne laktacije ostvaren je prosečan prinos od 7241 kg mleka sa 3,56% mlečne masti. Posmatran je i uticaj važnijih negenetskih faktora (farme, godine, sezone teljenja) na ispoljenost osobina mlečnosti. Ustanovljen je visoko značajan uticaj ispitivanih faktora na varijabilnost posmatranih proizvodnih svojstava (P< 0.01)

INFLUENCE OF PHYSICAL TRAINING ON CARDIORESPIRATORY ENDURANCE IN PREADOLESCENT AGE

Cardiorespiratory or aerobic endurance is the ability of the whole body to sustain physical activity for an extended period of time, involving relatively large groups of muscles. The attitudes on the possible impact of training on cardiorespiratory endurance in preadolescents are contradictory. Our study enrolled 195 boys aged 11 to 12 years. Experimental group (n=92) consisted of the children who had been involved with planned and programmed water polo training for at least two years. Control group (n=103) consisted of schoolchildren who only had had regular physical education in schools. Our investigation protocol included standardized anthropometric measurements and tests, performed respecting the appropriate protocols. Statistical analysis of the results demonstrated that there were no significant differences in age and relative values of oxygen consumption (VO2peak). Body height and mass, as well as the skinfold thickness, were significantly higher in experimental group subjects. The values of absolute VO2peak, FVC and FEV1.0 were also significantly higher in the examinees involved with water polo training. These findings stress the importance of a systematic training process even in this early period of growth and development in order for the trainees to acquire important functional advantages. We believe that a properly planned and programmed physical training can significantly contribute to the development of cardiorespiratory endurance even as early as preadolescent age
