Purpose This study compares two electromagnetic articulographs manufactured by Northern Digital, Inc.: the NDI Wave System (from 2008) and the NDI Vox-EMA System (from 2020). Method Four experiments were completed: (a) comparison of statically positioned sensors, (b) tracking dynamic movements of sensors manipulated using a motor-driven LEGO apparatus, (c) tracking small and large movements of sensors mounted in a rigid bar manipulated by hand, and (d) tracking movements of sensors rotated on a circular disc. We assessed spatial variability for statically positioned sensors, variability in the transduced Euclidean distances between sensor pairs, and missing data rates. For sensors tracking circular movements, we compared the fit between fitted ideal circles and actual trajectories. Results The average sensor pair tracking error (i.e., the standard deviation of the Euclidean distances) was 1.37 mm for the WAVE and 0.12 mm for the VOX during automated trials at the fastest speed, and 0.35 mm for the WAVE and 0.14 mm for the VOX during the tracking of large manual movements. The average standard deviation of the fitted circle radii charted by manual circular disc movements was 0.72 mm for the WAVE sensors and 0.14 mm for the VOX sensors. There was no significant difference between the WAVE and the VOX in the number of missing frames. Conclusions In general, the VOX system significantly outperformed the WAVE on measures of both static precision and dynamic accuracy (automated and manual). For both systems, positional precision and spatial variability were influenced by the sensors' position relative to the field generator unit (worse when further away).

Solimões River

This study evaluates the total length of tambaqui (Colossoma macropomum ) captured in the middle Solimões river and traded during seven years (1993, 1997 and 2000 to 2005) in the Tefé market, Amazon, Brazil. The Mamirauá Institute of Sustainable Development obtained measurements of the total lengths from 42207 individuals. The length average was 45.23 ± 6.29 cm (minim um of 13 cm and maximum of 105.5 cm ) and the mode was 45 cm . From the total tambaquis, 92.86% were smaller than 55 cm and 7.14% measured 58.24 ± 5.41 cm on average. Medium and standard deviation of the lengths recorded in all years showed sizes below the established by the environmental federal agency. The Kruskal Wallis test showed that there is no significant difference between the abundances and medium sizes of the captures during all months of the year. The historical data of the tambaqui fisheries for the middle Solimões region indicate that individuals of this species have been constantly captured at sizes below the minim um length of reproduction. Nine recommendations for tambaquis fisheries management in the region related to more efficient mechanisms of inspection, auto-ecology studies of the species, environmental protection, reduction of fishery pressure, diffusion and educational cam paigns that aim to correct exploitation of this resource are presented in this manuscript.

Background: Early marriages are at high risk of marital failure, poor family quality, young pregnancies at risk of maternal death, and the risk of being mentally ill to foster marriage and be responsible parents. Objective: To determine the effect of reproductive health education on peer groups (peers) on the knowledge and perceptions of adolescents about marriage age maturity. Method: This research uses the Quasi experimental method with One group pre and post test design, conducted from May to September 2018. The statistical analysis used in this study is a paired T test with a confidence level of 95% (α = 0, 05). Results: There is an average difference in the mean value of adolescent knowledge between the first and second measurements is 0.50 with a standard deviation of 1.922. The mean difference in mean scores of adolescent perceptions between the first and second measurements was 4.42 with a standard deviation of 9.611. Conclusion: There is a significant difference between adolescent knowledge on the pretest and posttest measurements with a value of P = 0.002, and there is a significant difference between adolescent perceptions on the pretest and posttest measurements with a value of p = 0.001. Increasing the number of facilities and facilities related to reproductive health education by peer groups (peers) in adolescents is carried out on an ongoing basis at school, in collaboration with local health workers as prevention of risky pregnancy.

This study investigates the use of unmanned aerial systems (UAS) mapping for monitoring the efficacy of invasive aquatic vegetation (AV) management on a floating-leaved AV species, Nymphoides cristata (CFH). The study site consists of 48 treatment plots (TPs). Based on six unique flights over two days at three different flight altitudes while using both a multispectral and RGB sensor, accuracy assessment of the final object-based image analysis (OBIA)-derived classified images yielded overall accuracies ranging from 89.6% to 95.4%. The multispectral sensor was significantly more accurate than the RGB sensor at measuring CFH areal coverage within each TP only with the highest multispectral, spatial resolution (2.7 cm/pix at 40 m altitude). When measuring response in the AV community area between the day of treatment and two weeks after treatment, there was no significant difference between the temporal area change from the reference datasets and the area changes derived from either the RGB or multispectral sensor. Thus, water resource managers need to weigh small gains in accuracy from using multispectral sensors against other operational considerations such as the additional processing time due to increased file sizes, higher financial costs for equipment procurements, and longer flight durations in the field when operating multispectral sensors.

Aim: This research was conducted to examine the attitudes of students studying at Fırat University Faculty of Sport Sciences towards sport tourism. Methods: 1091 students participated in the study. In order to examine the students' attitudes towards sports tourism, the attitude scale towards sports tourism (STYTÖ) developed by Kardaş and Sadık (2018) was used. The data obtained were evaluated in the SPSS 22.0 package program. Frequency, mean, standard deviation, one-wayAnova, independent t-test were used to analyze the data. The significance level of the statistics made was accepted as p <.05. Conclusion: As a result of the study, it was determined that the students' attitudes towards sports tourism were at a positive level and there were signifi-cant differences in terms of some variables (age, class, mother and father education level, branch, department, etc.) according to the sub-dimensions of the scale. It was deter-mined that there was no significant difference in terms of gender, marital status and sports tourism course variables. It is predicted that this research will provide an advantage in determining the attitudes of university students who receive sports education towards sports tourism and evaluating the issue in the sectoral field.

AbstractBACKGROUNDNumerous minimally invasive approaches to the skull base have been successively developed. Knowledge of the surgical nuances of a specific approach may facilitate approach selection. This study sought to compare the nuances of an extended version of the minipterional craniotomy (EMPT) with those of the transorbital endoscopic approach (TOEA) to the anterior and middle cranial fossae (ACF and MCF, respectively).OBJECTIVETo quantitatively analyze and compare the area of exposure and surgical freedom between EMPT and TOEA to the ACF and MCF.METHODSEMPT and TOEA were carried out in 5 latex-injected cadaveric heads, bilaterally (10 sides). For each approach, the area of exposure, surgical freedom, and angle of attack were obtained with neuronavigation and statistically compared.RESULTSNo significant difference was found between the mean area of exposure of EMPT and TOEA at the ACF and MCF (P = .709 and .317, respectively). The mean exposure area at the ACF was of 13.4 ± 2.6 cm2 (mean ± standard deviation) and 13.0 ± 1.9 cm2 for EMPT and TOEA, respectively. Except for the crista galli, EMPT afforded a larger area of surgical freedom at all targets. EMPT also achieved significantly greater attack angles in vertical axis except to the crista galli. The horizontal attack angles to all targets were similar between approaches.CONCLUSIONEMPT and TOEA offer a comparable area of exposure at the ACF and MCF in the cadaver; however, the instrument maneuverability afforded by EMPT is superior. Further studies are necessary to better define their precise surgical application.

The self-concepts of 10 5-yr.-old girls enrolled in a preballet program at a ballet school in Tulsa, Oklahoma for over one year were measured using the Purdue Self-concept Scale for Preschool Children. Their scores were compared against the scale's normative data for girls of similar age. A one-sample two-tailed t test showed girls' mean was 1 standard deviation above the normative population's mean, a significant difference. Preballet education may be an effective tool for enhancing self-concept, although selective factors may contribute also.

ObjectiveIt was to evaluate the degree of fatigue in patients with paralytic poliomyelitis (PP) and with post-polio syndrome (PPS), and correlate it with parameters of sleep and the circadian cycle.MethodsThirty patients, 17 female (56.7%), participated in the study: they answered the Revised Piper Fatigue Scale and performed a nocturnal polysomnographic study. Eleven had PP (mean age±standard deviation of 47.9±6.4 years), and 19 had PPS (mean age±standard deviation of 46.4±5.6 years).ResultsOur study showed that fatigue was worse in the afternoon in the PP Group and had a progressive increase throughout the day in the PPS Group. We also observed compromised quality of sleep in both groups, but no statically significant difference was found in the sleep parameters measured by polysomnography.ConclusionFatigue has a well-defined circadian variation, especially in PPS Group. Poor sleep quality is associated with fatigue and, therefore, sleep disturbances should be evaluated and treated in this group of PPS.

PURPOSE: To evaluate the shear bond strength (SBS) of metallic brackets bonded with Transbond Plus Self-Etching Primer (TPSEP) and Transbond Plus Color Change (TPCC) under contamination with a mixture of saliva and blood. MATERIALS AND METHODS: 42 human premolars were randomly divided into 2 groups (n=21). Group 1 (G1) were bonded under no contamination, and Group 2 (G2) was contaminated with saliva/blood before bonding. Both groups were bonded according to the manufacturer’s instructions and were cleaned with pumice before bonding. The shear bond strength (SBS) tests were performed after 24 hours in distilled water at 37°C and after thermocycling. RESULTS: Both groups showed a homogeneous distribution in the Levene’s test (p>0.05). The main shear bond strength value of G1 was 8.89 MPa with a standard deviation of 2.27; the value for G2 was 6.00 MPa with a standard deviation of 2.62 MPa. There was a significant difference between G1 and G2 (t-student test p<0.05). IRA scores indicated that the main value was IRA 0, and no significant difference (α=0.05) was found between the groups. CONCLUSION: Contamination of blood mixed with saliva significantly decreases the shear bond strength, but even so, the performance is clinically acceptable.

This study will use the Kirkpatrick Assessment Model to assess the School Excellence program through Organization Development (PrOD). This model involves evaluation of reactions, learning (knowledge, skills and attitude), behavior and outcomes, but this study only assesses knowledge and behavior . This study uses survey method by involving 120 respondents of the study chosen by group sampling. The instrument is a questionnaire that has Cronbach Alpha value between 0.930-0.984. The data were analyzed using mean score, percentage, standard deviation and regression. Analysis findings show that there is a significant difference between the level of knowledge and behavior before and after the PrOD. Overall, this study recommends PrOD to be continued, but it is necessary to improve in the formulation of PrOD syllabus so that school leaders can improve the behavior change in meaningful and meaningful implementation of the PrOD.
