Analysis of the Influence of Age Stages on Static Plantar Pressure Indicators for Karate Do Practitioners (Preliminary Report)

The investigation aims at static examination and determination of differences for three age groups: under 13, 13–15 years old and over 15, all practitioners of the martial art karate do. This investigation occured at the level of the main parameters, measured using the FreeMed baropodometric platform and Free Step software by Sensor Medica: plantar surface areas, location of the pressure center (C) inside the support polygon, imbalances noticed at the level of the plantar areas, Pmax value, weight distribution on each foot and at the level of the rearfoot and forefoot areas, misalignments of the pressure centers of each foot, etc. Results: subjects under the age of 13 had the highest number of cases related to the off-centered positioning of the pressure center (C); the groups of those under 13 and over 15 years old located in most cases Pmax at the level of the left retropodal part, and those between 13–15 years old have a location on the dominant leg, at the level of the right retropodal part. The highest numbers of cases of normal bilateral leg are for the group under 13 years, and the other groups have a higher incidence of various plantar imbalances. The analysis of variance (F) identified only two situations in which the independent variable, “age stages,” significantly influences the resulting parameters, at the level of the non-dominant foot: forefoot_left_surface and total_left_surface. The data differences for the right/left pairs within each batch generate insignificant values of |Z| for most cases, with the superiority of the dominant foot parameters for the first two age groups, but in the case of the group over 15 years old, some results are atypical, with higher average values of left/non-dominant foot parameters in the following cases: total_left_Pmax, total_left_Pavg, rearfoot_left_load_percent, rearfoot_left_weight_ratio_percent. The comparison between the data pairs for all three batches (between the forefoot and rearfoot plantar areas) generated significant values of |Z| only for the area of the plantar surfaces. The older the subjects, the more obvious the plantar load on the forefoot area, which is similar to the results of some martial arts studies analyzed here, and is determined by the long use of the non-dominant foot as a support base, during kicks with the dominant one.

Abstract Objective The aim of this study is to measure the average corpus callosum (CC) volume of healthy Turkish humans and to analyze the effects of gender and age on volumes, including the genu, truncus, and splenium parts of the CC. Patients and Methods Magnetic resonance imaging brain scans were obtained from 301 healthy male and female subjects, aged 11 to 84 years. The median age was 42 years (min–max: 11–82) in females and 49 years (min–max: 12–84) in males. Corpus callosum and its parts were calculated by using MRICloud. CC volumes of each subject were compared with those of the age and gender groups. Results All volumes of the CC were significantly higher in males than females. All left volumes except BCC were significantly higher than the right volumes in both males and females. The oldest two age groups (50–69 and 70–84 years) were found to have higher bilateral CC volumes, and bilateral BCC volumes were also higher than in the other two age groups (11–29 and 30–49 years). Conclusion The results suggest that compared with females/males, females have a faster decline in the volume of all volumes of the CC. We think that quantitative structural magnetic resonance data of the brain is vital in understanding human brain function and development.

This study has important implications for microworlds such as Logo, HyperGami, and Newton's World, which use interaction to learn spatial mental models for science, math, geometry, etc. This study tested the hypothesis that interactively rotating (dragging) virtual shapes primes mental rotation. The independent variable was observation vs. interaction: a) watching an animation of a shape rotating, versus b) manually rotating a shape on the computer. The dependent variable was mental rotation of the same shape. Two age groups, 9-year-olds and college undergraduates participated. For 9-year-olds, the interactive group mentally rotated significantly more accurately and faster than the observational. Therefore, interaction primed mental rotation. For the college undergraduates, the interactive group mentally rotated significantly more accurately, but significantly slower than the observational group. This suggests that the interaction disrupted a routine process, causing undergraduates to switch strategies. Results from both age groups reinforce the educational value of more naturalistic interaction with virtual shapes, i.e., dragging is better than clicking.

It has been claimed that due to their experience in controlling two languages, bilinguals exceed monolinguals in certain executive functions, especially inhibition of task-irrelevant stimuli. Here we investigated the effects of bilingualism on an executive phonological task, namely the forced-attention dichotic listening task with syllabic stimuli. In the standard non-forced (NF) condition, the participants reported all syllables they heard, be it from the right or the left ear. In the forced-right (FR) and forced-left (FL) attention conditions, they had to direct their attention to either the right- or the left-ear stimulus and inhibit information coming to the other ear. We tested Finnish monolinguals and early simultaneous Finnish–Swedish bilinguals from two age groups: (30–50-year-olds and 60–74-year-olds). The results showed that the bilinguals performed better than the monolinguals in the FR and FL conditions. This supports the idea of a bilingual advantage in directing attention and inhibiting task-irrelevant stimuli.

This study aims to set the size ranges for male human body aged between 7 and 18, and to develop detailed body measurement criteria for each size. For that purpose, total 31 items were selected from the references of 5th SizeKorea Survey to carry out a statistical analysis, and they included 11 items for height, 15 for circumference and 15 items for length. Through the factorial analysis of those 31 items for body measurement, two dominant factors of obesity and height could be extracted as representative elements for body types. The circumference of waist was designated as the representative element for obesity factor, and the height as the representative element for height factor, and the size ranges were set to 3cm and 5cm intervals each for waste circumference and height. With two age groups of 7-12 and 13-18, the waste circumference and the height were cross-analyzed to decide high frequency sections, and based on this, the size ranges for 3D model development were decided. Lastly, detailed measurement specifications according to size ranges were developed through regression analysis. In this regression analysis, the circumference of waist was put as independent variable and the height as dependent variable. As a result, it was proved in this study that the circumference of waste was a strong element to explain obesity factor, and the height was to explain height factor in body measurement, and size specifications were developed according to different size ranges.

The intimate relation between the sensory and motor functions of the hands during object manipulation and exploratory touch, the well-known improvement in object handling and constructive performance in ontogenesis and the emergent laterality thereof, assume changes in morphognostic capabilities in children. In this study we tried to corroborate the hypothesis of Mesker that mature and lateralized finger-thumb opposition is preceded by a stage of two-sided manual form agnosia in preschool children, followed by acquisition of morphognosis of the fingers and, finally, the thumbs. This study examined the development of gnostic hand function in 290 children from 3 to 11 years of age who drew the outlines of a meaningless wooden object passively felt with each hand without visual control. Analysis showed a clear ontogenetic change across the two age groups of increasing morphognostic function: 48% of the 6-yr.-olds drew correctly what the fingers of both left and right hands had perceived (thumbs, 14%). Of the 11-yr.-olds 91% and 61% performed perfectly with the right and left hands, respectively. The fingers preceded the thumbs in reproduction by most children, and the correct reproduction by the left thumb precedes that of the right thumb. The ontogenesis of bimanual sensorimotor functioning is discussed in the light of cortical and callosal development.

The burials of armed women of the territory of forest-steppe Dnieper region of the Scythian Age are analysed in the paper. The presented series consists of 27 complexes which are located on the territory of the Forest-steppe region of the Right Bank of the Dnieper (21), Left Bank territories (3) and Terrace Forest-Steppe (3). 14 graves (half of the total number) had been robbed which makes the reliability and informational content of this sample quite suitable for research. The burials of the Amazons of this region were made in a kurgan except for one (ground or flat grave). The height of the mounds varies from 0.2 to 7.6 m, diameter — from 8.7 to 63 m. Only three graves in the group were inserted to the mound. The graves are represented by five types. Three types of the pits prevail (81.5 %), two variants of the catacombs are also presented (two and three respectively). The wide use of wood is one of the features of the structure of funerary complexes of the Forest-Steppe Amazons. Thus, the burial structures correspond to the Scythian traditions but have certain local specifics. All burials are inhumations. Individual burials are predominant. Age affiliation was detected in 11 cases (more than 40 %). Only two age groups of the deceased are represented — ranging from 15—20 to 35 years. The grave goods include various types of weapons (mainly arrows and spears), horse bridles, various decorations, including precious metals and semiprecious stones, mirrors, tools, sets of various tableware etc. These sets, on the one hand, seem to be common for the Amazons of European Scythia, and on the other hand, they have specific regional features. Kurgans with burials of armed women have a fairly broad date: from the second part — end of the 7th till the 4th—3rd centuries BC.

Two Age Groups

In young adults, the neural correlates of successful recollection vary with the specificity (or amount) of information retrieved. We examined whether the neural correlates of recollection are modulated in a similar fashion in older adults. We compared event-related potential (ERP) correlates of recollection in samples of healthy young and older adults (N = 20 per age group). At study, participants were cued to make one of two judgments about each of a series of words. Subsequently, participants completed a memory test for studied and unstudied words in which they first made a Remember/Know/New (RKN) judgment, followed by a source memory judgment when a word attracted a ‘Remember’ (R) response. In young adults, the ‘left parietal effect’ – a putative ERP correlate of successful recollection – was largest for test items endorsed as recollected (R judgment) and attracting a correct source judgment, intermediate for items endorsed as recollected but attracting an incorrect or uncertain source judgment, and, relative to correct rejections, absent for items endorsed as familiar only (K judgment). In marked contrast, the left parietal effect was not detectable in older adults. Rather, regardless of source accuracy, studied items attracting an R response elicited a sustained, centrally maximum negative-going deflection relative to both correct rejections and studied items where recollection failed (K judgment). A similar retrieval-related negativity has been described previously in older adults, but the present findings are among the few to link this effect specifically to recollection. Finally, relative to correct rejections, all classes of correctly recognized old items elicited an age-invariant, late-onsetting positive deflection that was maximal over the right frontal scalp. This finding, which replicates several prior results, suggests that post-retrieval monitoring operations were engaged to an equivalent extent in the two age groups. Together, the present results suggest that there are circumstances where young and older adults engage qualitatively distinct retrieval-related processes during successful recollection.

Choice of profession is a social phenomenon that every person has to face in life. Numerous studies convince us that not only the well-being of a person depends on the chosen work, but also his attitude to himself and life in general, therefore, the right and timely professional choice is very important. Research about factors of career self-determination of students of higher education institutions in Ukraine shows that self-determination is an important factor in the socialization of young person, and the factors that determine students' career choices become an actual problem of nowadays. The present study involved full-time and part-time students of Institute of Philology and Mass Communications of Open International University of Human Development "Ukraine" in order to examine the factors of career self-determination of students of higher education institutions (N=189). Diagnostic factors of career self-determination of students studying in the third and fourth year were carried out using the author's questionnaire. Processing of obtained data was carried out using the Excel 2010 program; factorial and comparative analysis were applied. Results of the study showed that initial stage of career self-determination falls down on the third and fourth studying year at the university, when an image of future career and career orientations begin to form. At the same time, the content of career self-determination in this period is contradictory and uncertain, therefore, the implementation of pedagogical support of this process among students is effective.
