Introduction: Military flying entails sound psychological health along with a high level of skill and aptitude. Pilots are selected on the basis of their psychological profile, psychomotor ability, and cognitive ability. Hence, the performance of pilots can be construed as a product of skill, attitude, and personality factors. Personality factors and cognitive ability have a vast impact on the flying performance and flight safety. This acquires a whole new dimension for flying instructors, as teaching the nuances of flying to a young flight cadet is a very challenging task. Materials and Methods: To study the personality and cognitive profile of the special group of flight instructors, 45 instructors and trainee instructors from flying instructors’ school, Tambaram, were administered NEO five- factor inventory and four cognitive tests comprising Stroop test, symbol-digit coding and digit span-backward and forward. The data were analyzed using descriptive statistics, t-test, and analysis of variance. Results and Discussion: Trainees and instructors constituted the sample wherein they were considered as a common group; hence, comparison between them was not carried out. The aircrew manifested emotional stability, high extraversion, willingness to experience novel experiences, low to average agreeableness, and average to very high conscientiousness. Their cognitive performance was compared with available norms for general population and was found to be above average. No significant difference was found in the personality dimensions or cognitive performance on the basis of mode of entry, stream, marital status, etc. Conclusion: Instructors came out to be more emotionally balanced, extraverted, and keen to have new experiences and had high conscientiousness compared to non-instructor pilots. The instructors showed above- average performance when compared to normative data provided by the test authors. It has implications for future studies with large samples and similar protocols.

Abstract Objective The Hopkins Verbal Learning Test–Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) are memory tests with embedded measures of performance validity (Recognition Discrimination [RD] and Discrimination Index [DI], respectively). We evaluated whether cognitive ability and age influenced embedded measures of effort. Methods Participants included 30 young adults (YA) and 29 older adults (dichotomized into unimpaired [OAu] and impaired [OAi]). Participants completed a medication management ability assessment (MMAA), daily memory lapses survey (DM), digit span, and the Transverse Patterning (TP) and Reversal Learning (RL) computerized tests. Two Repeated-Measures MANOVAs were conducted to determine if Passing PVT and Age/Cognitive Ability influenced performance. An ROC analysis was conducted for HVLT-RD and BVMT-DI to determine pass/fail, and false positives/negatives on embedded measures. Results Those in the YA group who failed RDS (YA-fail), performed better than OAi-fail and OAi-pass groups on RT Errors (p < .0001). On TP Errors, the YA group differed from all four OA groups (p < .0001). On MMAA a significant difference was observed between OAi-fail and all other groups (p < .001). On RD, YA groups differed from both OAi groups (p = .0008). On DI, the YA groups differed from the OAi-fail group (p = .002). A logistic regression classified 43/57 participants successfully into the three cognitive groups using the six predictors (χ2 = 55.73, p < .0001, R2 = .468). RT Errors and TP were significant (Likelihood χ2 = 7.25, p = .027). Conclusion HVLT-RD failed to detect validity for OAi, as did BVMT-DI for YA and OAu. Instead, impairment effects are seen on HVLT-RD and BVMT-DI where YA groups differed from some combination of both/one of the OA groups.

Introduction: Cardiovascular diseases have been associated with impaired cognitive performances, especially in functions. In contrast, it is clearly established that regular physical activity maintained throughout life protects against age-related cognitive decline. Purpose: to assess maximal oxygen uptake (VO2max), cardiac output, and cerebral hemodynamic changes, assessed by Near-Infrared Spectroscopy (NIRS), during a graded maximal exercise tests, and cognitive performance at rest in patients with stable coronary heart disease (CHD) and healthy matched adults. Methods: Ten stable CHD patients (67.1±10.5 years) and 9 age-matched controls (62.2± 11.4 years) were included in this pilot study. Measurements included: body composition (bioelectrical impedance), complete blood analysis in a fasting state, cognitive performance using validated neuropsychological tests, graded maximal exercise testing on ergocycle with gas exchange analysis, non-invasive cardiac output measurement (cardiac bioimpedance) and NIRS signals measurement at the left prefrontal brain level (oxyhaemoglobin: O2Hb, deoxyhaemoglobin: HHb ; total haemoglobin: THb, and differential haemoglogin: Hbdiff). Results: Several cognitive performance items were lower in the CHD group, especially regarding executive functions (Backward digit span score, p<0.05; trail making test B, p=0.05; Stroop test (inhibition/flexibility), p<0.05). There was no difference between CHD and controls in VO2 max (29.7±8.5 Vs 32±6.3 ml/kg/min) and maximal cardiac output (15.5±3.9 Vs 17±2.6 l/min), whereas cardiac output and cardiac index at the ventilatory threshold were lower in CHD (5.75±1 Vs 7.06±0.6 l/min/m2, p<0.05, and 11.2±2.2 Vs 14.1±2.8 l/min, p<0.01, respectively). There was a significant difference in the kinetics of NIRS signal with higher amplitude for CHD patients vs. controls for O2Hb (p<0.01); THb (p<0.05) and Hbdiff (p<0.05). Significant higher amplitude were also found for O2Hb, THb, Hbdiff (p<0.0001) in younger (62 years) participants. HHb (p<0.0001) and Hbdiff (p<0.01) amplitude was higher for fit (≥120% theoretical VO2max) vs. less fit (<120%) participants. Discussion: Compared to age-matched controls, our sample of stable fit CHD patients had a comparable maximal exercise tolerance and cardiac output, with higher NIRS cerebral signals amplitude for O2Hb, THb and Hbdiff. This latter parameter thus does not seem to influence cognitive performance at rest, that was lower in CHD patients, especially in executive functions. However, an important inter-individual variability of cerebral NIRS signal amplitude was observed, with age and fitness appearing as major contributors. We plan to recruit a larger sample of subjects to assess more clearly relationships between exercise, tolerance hemodynamic parameters and cognitive performance.

Abstract Memory loss is a major complaint among the elderly population. However, the clinical significance of this symptom is variable and also controversial in the scientific literature. Objective: To compare the cognitive performance of two groups of healthy elderly, one group with and the other without, subjective memory complaints (SMC). Methods: Sixty cognitively intact elderly individuals (39 females and 21 males), aged 69.9±6.3 years and with educational level of 8.5±5.5 years, were included in the study. Participants were submitted to the Mini-Mental State Examination and to the Cornell depression scale in order to rule out global cognitive impairment and depression, respectively. Moreover, they answered the MAC-Q, a questionnaire devised to evaluate subjective impression of memory function. Subsequently, they were submitted to the digit span forward and backward, the Brief Cognitive Screening Battery, and to the Frontal Assessment Battery. Results: Twenty-seven individuals had MAC-Q scores <25 and thus were classified as not having SMC, while 33 had MAC-Q scores ³25 and were considered to have SMC. No differences for age, gender, education and MMSE scores were found between the two groups. The comparison between the performance of the groups of complainers and non-complainers on the different cognitive tests yielded no significant difference, although there was a trend toward non-complainers performing better on incidental memory. Conclusions: The presence of SMC was not associated to objective memory impairment or to other cognitive deficits in this group of elderly individuals.

The purposes of this study were to investigate differences in personality and competitive anxiety depending on types of sports and gender, and to determine the influence of personality on competitive anxiety. Participants included 237 athletes (134 men and 103 women) who participated in the Thailand University Games, 2020. They were classified as individual (n = 114) and team (n = 123) athletes. Personality characteristics and competitive anxiety were assessed by using NEO five-factor inventory and sport competitive anxiety test. Differences between individual and team athletes and between gender were tested by using independent t-test. Relationships between personality and competitive anxiety were analyzed by using Pearson product-moment correlation coefficient. Moreover, multiple regression analysis was used to measure the contributions of personality on competitive anxiety. The results showed that competitive anxiety was significant difference between individual and team athletes (p = 0.03, d = 0.28). However, there was no difference in personality between groups. When compared between gender, there were significant differences in competitive anxiety (p < 0.001, d = 0.52) and the agreeableness (p = 0.04, d = -0.26) component of personality between female and male athletes. From the correlation analyzes, four characteristics of personality showed significant associations with competitive anxiety including neuroticism (r = -0.472, ρ < 0.001), extraversion (r = 0.184, ρ = 0.005), agreeableness (r = 0.147, ρ = 0.024), and conscientiousness (r = 0.202, ρ = 0.002). Among five personality factors, the neuroticism had minimally negative effect on competitive anxiety (β = -0.52) with percentage of prediction of 22%. These can be concluded that types of sport and gender are the important factors affecting personality and competitive anxiety. The athletes with certain personality traits were more susceptible to competitive anxiety. Importantly, the neuroticism could serve as a prediction of the competitive anxiety in all collegiate athletes.

The Relationship

This study investigates the relationship between personality factors, leadership and organizational citizenship behaviour (OCB), predict changes in OCB by personality and leadership, and analyze the influence of demographic variables (organizational tenure, educational qualifications, age, designation, gender and job status) on OCB, personality, leadership and their dimensions. The sample consisted of 203 employees from three units of Sesa Goa Ltd., a leading mining company in Goa. Three reliable and valid tools were employed for the assessment-Organizational Citizenship Behaviour, NEO Five Factor Inventory and Leadership Effectiveness scale. Results of correlation analysis indicated positive correlation between leadership (all dimensions) and OCB. Of five personality factors, extraversion, agreeableness and conscientiousness showed positive correlation while neuroticism was found to be negatively correlated with OCB. Furthermore, result of regression analysis unveiled that 18% variance in OCB is contributed by leadership and 11% by personality. Unit wise differences were also evident in OCB. An incidental analysis using One Way ANOVA and t test revealed significant influence of organizational tenure and educational level on OCB. No significant difference was noticed on leadership and any of its dimensions. This study provides guidelines to aid managers better understand how to enhance OCB.

And Control

This pilot study compared cognitive performance in short-duration computer-based tasks between static sitting as control, and active sitting with use of a dynamic foot movement device as intervention. Using a within-subjects counterbalanced design; participants performed four computer-based tasks evaluating cognitive performance. A survey reported subjective evaluations of concentration, productivity, comfort, satisfaction, and preference for future use. Results from Digit span, Fitts’ Spiral, Stroop and Typing tests indicate no significant difference in cognitive performance between intervention and control. Survey results suggest that 40% of participants expressed satisfaction and preference for future use of the intervention. In conclusion, findings from this study suggest that compared to static sitting, cognitive performance on short-duration computer tasks is not reduced with use of a dynamic foot movement device. The adoption of dynamic foot movement devices can potentially increase low-intensity concurrent physical activity without negatively impacting cognitive performance in short-duration computer-based office tasks.

Sensation Seeking Scale

Introduction. Internationally, there have been several studies carried out in order to demonstrate the relationship between a high level of Sensation Seeking and illegal drug abuse. However, few studies in Colombia replicate those results. The objective is to examine the difference of Sensation Seeking personality trait and its subscales in the behaviour of drug abuse on two Colombian samples, consumers and non-consumers, measured through the Sensation Seeking Scale-V (Zuckerman & Kulhman, 1980). Methodology. 341 adult subjects, from both genders, composed the sample, half of them were consumers of illegal drugs and half of them non-consumers, assessed through Sensation Seeking Scale Version V. Results. There is a significant difference between consumers and non-consumers within the general scale and three subscales of the trait (Thrill and Adventure Seeking, Experience Seeking and Disinhibition). Discussion. Differences between the scores of consumers and non-consumers sample regarding the general trait and subtraits show the relevance of personality factors regarding substance abuse, independently than social and learning factors are influential as well. Conclusions. There is a link between Sensation Seeking and substance abuse showing the importance of the level of the trait in the multivariate phenomenon of substance dependence.

Implant-supported prostheses hygiene and peri-implant tissues health are considered to be predictive factors for successful prosthetic rehabilitation. Therefore, the purpose of this study was to evaluate the effectiveness of brushing associated with oral irrigation measured as biofilm-removing capacity, maintenance of healthy oral tissues, and patient satisfaction. A randomized, crossover clinical trial was conducted with 38 patients who wore conventional maxillary complete dentures and mandibular overdentures retained by the O-ring system. The patients were instructed to use the following hygiene methods for 14 days: mechanical brushing [MB (brush and dentifrice - Control)]; and MB with oral irrigation [WP (Waterpik - Experimental)]. Biofilm-removing capacity and maintenance of healthy oral tissues were evaluated by the Modified Plaque Index (PI), Gingival Index (GI), Probing Depth (PD), and Bleeding on Probing Index (BP) recorded at baseline and after each method. In parallel, patients answered a specific questionnaire using a Visual Analogue Scale after each hygiene method. Data were analyzed by Friedman and Wilcoxon tests (α=0.05). The results showed significantly lower PI, GI, PD, and BP indices after application of the hygiene methods (P&lt;0.001) than those observed at baseline. However, no significant difference was found between MB and WP. The satisfaction questionnaire responses to both methods showed high mean values for all questions, with no statistically significant difference found between the answers given after the use of MB and WP (P&gt;0.05). The findings suggest that WP was effective in reducing PI, GI, PD, and BP indices and provided a high level of patient satisfaction.

The article studies correlation between kappa casein genotypes (C3N3), beta-lactoglobulin (LGB), their complexes and milk production indices in cows bred under equal conditions at a breeding farm. The calculation of parental milk yield and fat indices between the three breeds showed a significant difference (P>0,999) of PCI of Ayrshire and Holstein cattle breed milk yield - 3395 kg, PCI of fat - 0,22%; between Holstein and Yaroslavl cattle breeds - 3200 kg, PCI offat - 0,16%. A significant difference of realization indices of protein between all three breeds was not stated. The highest realization ofparental milk yield index was stated - between Ayrshire and Yaroslavl cattle breeds- 113%, Holstein cattle breed - 88%. As for the fat and protein indices, all three cattle breeds showed a high realization of PCI from 98% to 109%. However, Holstein cattle breed showed the highest percentage: protein - 101%, fat - 109%. A significant difference of PCI realization of milk productivity in CSN3 and LGB genotypes was not stated. It was also stated that there is a tendency of high level parental indices realization when there is a higher number of B-allele variants in genotypes of cows.

Total twenty different processed meat plant producing emulsion type sausage were histologically and chemically examined for detection of adulteration with unauthorized tissues. Results revealed that samples were adulterated with different types of animal tissues included; hyaline cartilage, tendon, spongy bone, peripheral nerve trunk, basophilic matrix, lymphatic tissue, fascia, fibrocartilage and vascular tissue. Moreover, these samples were adulterated Also, adulterated with plant tissue included; plant stem, leaves and root. Chemical analysis showed a significant difference in their chemical composition (moisture, fat, protein, ash and calcium) content. Moisture and fat content varied around the permissible limit of E.S.S. while low protein, high ash and calcium content was detected in the examined samples. Therefore, Histological and chemical examinations can be used as reliable methods to detect adultration using unauthorized addition of both animal and plant tissues in processed meat product samples which revealed a high level of falsification.
