The paper presents the results of empirical validation and verification of the reliability of the Adapted Warner status characteristic index (Warner’s AISC). Earlier, the adaptation of Warner’s ISС was carried out, and the level of theoretical (obvious and substantial) validity was checked. As a part of checking the level of empirical validity of Warner’s AISC, the level of validity by criteria and construct validity was measured. Two face-to-face surveys (2017–2018) were used as the empirical basis for the study. The validity by criteria was tested through holding a methodical experiment, that comparing two groups which differed significantly in terms of social status. Respondents in two different administrative districts of Kyiv were selected as such groups. The level of prestige of the district of residence differs significantly in terms of prestige. There were found that the mean value of Warner’s AISC in these groups differed significantly, which indicates a high level of validity by criterion. The relationships between the different indicators of the social status of respondents have been analyzed to test the level of validity of construct. Thus, the relationship between Adapted Warner’s Status characteristic index indicators and the results of the questions aimed at directly measuring the self-assessment of their position in society was analyze: 1) integral self-assessment of social status using a seven-point scale; 2) a subjective assessment of the financial situation, within the framework of which the respondent is asked to assess his own financial condition. The mean values of Warner’s AISC in the deferent groups by the level of self-esteem differ significantly. The results obtained speak in favor of the construct validity of Warner’s AISC. With regard to the reliability of the index, it has been concluded that it would be useful to measure the retest reliability of the instrument. Because of the causality characteristics of the composite index we can’t use assessment of usability. The validation results of the Adapted Warner status characteristic index indicate a high level of empirical validity of the instrument.

Objectives: To compare the linear measurements from digital panoramic (DP) radiographs and cone-beam computed tomography (CBCT) volumes for the localization of the mental foramen (MF). Material and Methods: Thirty-one patients with panoramic and CBCT radiographs depicted on the same machine were analyzed. The vertical and horizontal positions of the MF were compared by the differences in distances measured from reference points to the boundaries (tangents) of the MF in digital panoramic (DP) and CBCT reformatted panoramic (CRP) views. The vertical position of MF was also analyzed on CBCT oblique coronal views (CORO) and compared with its corresponding distances on DP and CRP views. Results: Statistically significant differences (P < 0.05) were found in all compared measurements between CRP and DP views. In addition, the vertical distance (Y1) compared between DP, CRP, and CORO views also showed a statistically significant measurement discrepancy in the mean distance (P < 0.000) with the highest mean difference of 1.59 mm (P < 0.05) was attained from Y1 (DP-CORO). Inter- and intra-examiner analysis indicated a high level of agreement for all measurements. Conclusion: The mean values of discrepancies in measurements between DP and CRP views for horizontal and vertical linear measurements were clinically tolerable. Nevertheless, significant differences in the vertical MF position were detected between the panoramic views (DP, CRP) and the coronal views (CORO). This implies that the use of coronal view measurements during implant planning might reduce the risk of neurovascular injuries.


The role of social support at workplace become one of the most important variables that can give impact on employee’s attitude. Closely related to employee’s performance, many studies have confirmed the role of social support in enhancing employee’s job satisfaction. The aims of this research is two-folds. First, to investigate the differences and second to compare the effect of social support on job satisfaction among academicians in Malaysia. Overall, a total of 420 samples were obtained, wherein 210 participants withdrawn from each setting. Data was collected using self-administrated questionnaire, and analyzed using SPSS version 22. The finding suggested that social support levels (i.e. supervisor support and co-worker support) are higher among academicians in private university. Level of job satisfaction, otherwise is higher among public university. Overall, the mean values indicated high level of social support and job satisfaction among academicians in both university. Analysis of t-Test revealed that there is no significant differences in terms of social support, however the significant being observed in terms of job satisfaction between academicians in Malaysia public and private university. This study also ascertained the positive impact of social support on job satisfaction to both samples. Implication of this study includes empirical contribution and deliberation on social support and job satisfaction. Suggestion from this study includes improving social support to enhance overall academicians’ job satisfaction.

The genetic variability of some Nigerian breeds of sheep at the IGF 1 locus was investigate blood samples from 150 sheep (50 each of Yankasa, Balami and Uda sheep) were collected from the Maiduguri abbatoir and analysed at the Biotechnology centre of the University of Maiduguri. A relatively high level of genetic variability was detected in Nigerian sheep; the mean observed heterozygosity (Ho) and expected heterozygosity (He) values were 0.433 and 0.476, respectively. Comparison of expected heterozygosity of alleles between the populations showed that yankasa was the most heterozygous of the sheep populations though the unbiased expected heterozygosity (0.503) for the Yankasa was the same as that of the Balami. All populations were 100% polymorphic at the IGF 1 locus with fixation index ranging from -0.169 to 0.378 and a mean of 0.093, which suggests a general pattern of random mating. Similarly, low mean values for Fis (0.093), F (0.089), Fis (0.089), Fit (0.130) and Fst (0.045) supports the assertion that inbreeding was limited due to outcrossing with relatively high level of gene-flow (Nm = 5.292). The analysis of molecular variance (AMOVA) revealed that only 1% of the total variations observed in the sampled populations is accounted for by the population differences while individual differences accounted for 85%. The UPGMA phylogenetic tree revealed that the Uda and Yankasa populations are closer to each than each is to Balami. Thus, it can be concluded that sufficient genetic variation exist in the studied Nigerian sheep breeds and these populations are unlikely to decline due to inbreeding.

AbstractTomato is known as a vegetable with several health benefits due to its high level of bioactive compounds, especially lycopene, phenolics, and vitamin C. The effect of tomato variety and stage of maturity on the bioactive compounds concentration was studied. Ten tomato varieties were grown and collected from a greenhouse at two different stages of ripening. The obtained results showed that there were significant differences in the mean values between analysed parameters according to the stage of ripening and variety. The highest concentration of vitamin C was determined for variety Sakura F1 at maturity stage, and the lowest for variety Sunstreem F1 for unripe fruits. The concentration of phenols and flavonoids increased during tomato ripening and the highest rate was observed for variety Naget F1 (from 7.86 mg·100g−1to 14.34 mg·100 g−1(phenols) and flavonoids from 6.09 mg·100 g−1to 10.03 mg·100 g−1. The concentration of lycopene in the unripe stage was low (mostly about 1 mg·100 g−1) and the most quantitative changes and the highest concentration of lycopene in full maturity stage was determined for variety SV0946TS (27.11 mg·100 g−1) and variety NectarF1 (16.81 mg·100 g−1).

Toxicity of toluene arising from solvent abuse, occupation hazards and environmental pollution has generated a lot of concern in recent times. Young people are getting more involved in the abuse of toluene by deliberate inhalation of toluene-containing substances which may result in high level of exposure to toluene. This abuse may have adverse effect on their health. This study was therefore designed to investigate the effect of oral exposure to toluene on haematological parameters using male albino rats as model. Twenty animals were randomly assigned to 4 groups of 5 rats each. Group A (Control) received 0.5 ml of olive oil (vehicle) while groups B, C and D received 31.8, 63.6 and 127.2 mg/kg respectively of toluene for 21 days by oral gavage. At the end of the treatments, the animals were anaesthetized and blood samples were collected for haematological investigations. No significant (p >0.05) variation occurred in the mean values of PCV, haemoglobin concentration, RBC and platelet counts in comparison with the control. There was a significant (p <0.05) increase in total WBC and lymphocyte counts with a higher increase (p<0.01) in total neutrophil count.  No significant (p >0.05) change in the total monocyte and eosinophil counts relative to the control. Oral administration of toluene as used in this study may be toxic to health depending on the dose and duration of exposure.

SummaryFibrinolysis and the last stage of clotting were examined in 20 healthy infants on days 1-4 after birth. Plasminogen was constantly at half its normal level: 1.2-1.4 u/ml. The euglobulin lysis was increased only on day 1 in 50% of the cases. The mean values on days 1 and 4 showed a statistically significant difference: 0.45 ± 0.20 and 0.14 ± 0.05 (t = 2.1 p < 0.05). Fibrinogen was low or low normal at birth (mean values: 230 ± 57 mg%) but increased significantly in the next days reaching a mean of 293 ± 41 mg% on day 4 (t = 3.6 ρ < 0.001). Factor XIII was normal in all cases. Increased fibrinolysis in day 1 is probably due to a high level of activator at birth and the low plasminogen and fibrinogen are probably a consequence of the physiological „immaturity” of the liver.

Aim. Over the last few years an increasing number of people have started training out with kettlebells (KBs) all over the world. Unfortunately, there is very little scientific data about the effect of training with KBs, and essentially no research has been done on the various kettlebell sports which are developing dynamically. The main aim of this paper was to analyse the intensity of physical effort during the 10 minute Snatch Test (10 min ST) at the HardStyle Kettlebell Polish Championship (HSKPC). Our research also included an analysis of the contestants’ body composition on the competition day. Basic procedures. Ten male contestants and five female contestants were examined. Physical effort intensity was measured using Polar Team2 Pro. Body composition was evaluated with the Tanita SC-330 immediately before the start of the competitions. The mean values of the analyzed parameters in the study contestants were compared with the best male and female contestants of the Championship. Results. The heart rate during intensive exertion for the 10 min ST was consistently at a high level (80-89% HRmax) or very high level (90-100% HRmax). Such a high HR was maintained for 98% of the exercise performance, and the mean relative energy expenditure were 14.4 METs among the women and 15.5 METs among the men. An analysis of body composition showed that participants of the HSKPC were characterized by an athletic build. Conclusions. Even though the contestants lift relatively heavy loads during the 10 min ST (men 24 or 28 kg, women 16 kg) the effort can be described as an endurance test. Considering all the competitions taking place during the HSKPC and the results of the participants it can be stated that these competitions are unusually demanding and require versatile physical fitness, as well as strength, endurance and coordination. Key words: kettlebell, snatch test, physical effort, Hardstyle

For this work were taken measurements of the skinfolds of Russian children and adolescents of both sexes 7-17 years old, with a total number of 1103 pupils. Was made a comparison of the mean values of the average skinfolds. Results and discussion. In the investigated group significant differences in the average thickness of the skinfolds were revealed between the initial set of Matiegka and the modification of Lutovinova et al. The revealed differences significantly influenced the final estimates of the mass of body fat. However, the estimates obtained turned out to be highly correlated and with a high level of agreement, on the basis of which conversion formulas between them were proposed. Conclusion. When using Matiegka's formulas, it is necessary to give a detailed description of the method for measuring skinfolds, taking into account the influence of the choice of skinfolds on the final estimate of the fat mass.

The three objectives of the present review of the literature were to: characterize the evolution of habitual physical activity (HPA) during growth; evaluate the tracking of HPA from childhood to adulthood; and analyse the level of HPA in children and adolescents according to public health recommendations. Data indicates that HPA decreases from childhood to adulthood about 7% per year, with a great reduction during puberty and adolescence concurrent to changes in the type of physical activity. It appears that HPA is not quite steady (0.09 <  r <  0.66) during growth, which means that behavioural changes occur. Being very active during childhood or adolescence does not necessarily translate into a high level of HPA in adulthood. The mean values of HPA of children and adolescents vary from 15 to 90 min•day−1 between studies, and for most of them HPA has been higher or close to public health recommendations. However, these results mask a great number of children and adolescents who are inactive or becoming inactive (40 to 45% of the population). Key words: children, adolescents, heart rate monitoring, questionnaire, health

The continuous, accurate and reliable estimation of gait parameters as a measure of mobility is essential to assess the loss of functional capacity related to the progression of disease. Connected insoles are suitable wearable devices which allow precise, continuous, remote and passive gait assessment. The data of 25 healthy volunteers aged 20 to 77 years were analysed in the study to validate gait parameters (stride length, velocity, stance, swing, step and single support durations and cadence) measured by FeetMe® insoles against the GAITRite® mat reference. The mean values and the values of variability were calculated per subject for GAITRite® and insoles. A t-test and Levene’s test were used to compare the gait parameters for means and variances, respectively, obtained for both devices. Additionally, measures of bias, standard deviation of differences, Pearson’s correlation and intraclass correlation were analysed to explore overall agreement between the two devices. No significant differences in mean and variance between the two devices were detected. Pearson’s correlation coefficients of averaged gait estimates were higher than 0.98 and 0.8, respectively, for unipedal and bipedal gait parameters, supporting a high level of agreement between the two devices. The connected insoles are therefore a device equivalent to GAITRite® to estimate the mean and variability of gait parameters.
