Do Ergogenic Aids Alter Lower Extremity Joint Alignment During a Functional Movement Lunge Prior to and Following an Exercise Bout?
Authors: Mills Chris , Knight James , Milligan Gemma 
Published: May 2015

Abstract
Ergogenic aids have been used to alter joint kinematics in an attempt to minimise injury risk, yet the effectiveness of these aids may be compromised following a bout of exercise. This preliminary study aimed to measure the effect of compression garments and Kinesio Tape® on lower extremity joint alignment prior to and following an exercise bout. Eight male athletes (age = 24.1 ± 3.0 years, body height = 177.4 ± 5.2 cm, body mass = 72.3 ± 7.2 kg) volunteered to participant in this study. Joint kinematics were recorded whilst all participants performed three rotational lunges, in three conditions (control, compression garment, Kinesio Tape®), prior to and following a 10 minute exercise bout. Frontal plane kinematics (lateral pelvic tilt, knee valgus, ankle inversion/eversion) were used to assess ergogenic aid effectiveness during the lunge. Participants exhibited no significant differences in joint kinematics between ergogenic aid conditions prior to the exercise bout. Following exercise the only significant difference occurred within the Kinesio Tape® condition where maximum knee valgus angle significantly increased from 6.5° prior to exercise, to 7.7° following the exercise bout. The results of this study suggest joint kinematics are not affected by the ergogenic aids in this study prior to an exercise bout. However, there is evidence to suggest that the application of Kinesio Tape® may allow an increase in knee valgus angle following a bout of exercise, yet, compression garments are effective at maintaining joint alignment following a bout of exercise.

Abstract
This study examined the effects of a 6-week non-failure strength training program in youth tennis players. Twenty tennis players (age: 15.0 ± 1 years, body height: 170.9 ± 5.1 cm, body mass: 63.3 ± 9.1 kg) were divided into experimental and control groups. Pre and post-tests included half squats, bench press, squat jumps, countermovementjumps and side-ball throws. Salivary cortisol samples were collected, and the Profile of Mood States questionnaire was used weekly during an anatomical adaptation period, a main training period and after a tapering week. The results showed that, after the main training period, the experimental group significantly improved (p<0.05) in mean and peak power output and in the total number of repetitions during the half-squat endurance test; mean force, power and velocity in the half-squat power output test; Profile of Mood States (in total mood disturbance between the last week of the mean training period and the tapering week); and in squat-jump and countermovement-jump height. Moreover, significant differences were found between the groups at the post-tests in the total number of repetitions, mean and peak power during the half-squat endurance test, mean velocity in the half-squat power output test, salivary cortisol concentration (baselines, first and third week of the mean training period) and in the Profile of Mood States (in fatigue subscale: first and third week of the mean training period). In conclusion, a non-failure strength training protocol improved lower-limb performance levels and produced a moderate psychophysiological impact in youth elite tennis players, suggesting that it is a suitable program to improve strength. Such training protocols do not increase the total training load of tennis players and may be recommended to improve strength.

Abstract
The purpose of this study was to examine the association of the BstUI RFLP C/T (rs 12722) and DpnII RFLP C/T (rs 13946) COL5A1 polymorphisms, individually and as haplotypes, with anterior cruciate ligament ruptures in recreational skiers. Subjects were 138 male recreational skiers with surgically diagnosed primary anterior cruciate ligament ruptures. The control group consisted of 183 apparently healthy male recreational skiers, who were without any self-reported history of ligament or tendon injury. DNA was extracted from buccal cells donated by the subjects and genotyping was carried out using real-time PCR. The genotype distributions for both polymorphisms met Hardy- Weinberg expectations in both groups. There were no significant differences in genotype distribution of allele frequencies of COL5A1 BstUI RFLP C/T and COL5A1 DpnII RFLP C/T polymorphisms between the ACL rupture and control groups. The T-T (BstUI RFLP T, DpnII RFLP T) haplotype was the most common (55.6%). The haplotype T-C was not present in any of the subjects. There was an underrepresentation tendency of the C-T haplotype in the study group compared to controls under recessive mode of inheritance. Higher frequency of the COL5A1 BstUI RFLP C/T and COL5A1DpnII RFLP C/T polymorphisms haplotype is associated with reduced risk of anterior cruciate ligament injury in a group of apparently healthy male recreational skiers.

Published: May 2015

Abstract
The aim of the present study was to investigate relationships between a performance index derived from the Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1) and other measures of physical performance and skill in handball players. The other measures considered included peak muscular power of the lower limbs (Wpeak), jumping ability (squat and counter-movement jumps (SJ, CMJ), a handball skill test and the average sprinting velocities over the first step (VS) and the first 5 m (V5m). Test scores for 25 male national-level adolescent players (age: 17.2 ± 0.7 years) averaged 4.83 ± 0.34 m·s-1 (maximal velocity reached at the Yo-Yo IR1); 917 ± 105 Watt, 12.7 ± 3 W·kg-1 (Wpeak); 3.41 ± 0.5 m·s-1 and 6.03 ± 0.6 m·s-1 (sprint velocities for Vs and V5m respectively) and 10.3 ± 1 s (handball skill test). Yo-Yo IR1 test scores showed statistically significant correlations with all of the variables examined: Wpeak (W and W·kg-1) r = 0.80 and 0.65, respectively, p≤0.001); sprinting velocities (r = 0.73 and 0.71 for VS and V5m respectively; p≤0.001); jumping performance (SJ: r = 0.60, p≤0.001; CMJ: r= 0.66, p≤0.001) and the handball skill test (r = 0.71; p≤0.001). We concluded that the Yo-Yo test score showed a sufficient correlation with other potential means of assessing handball players, and that intra-individual changes of Yo-Yo IR1 score could provide a useful composite index of the response to training or rehabilitation, although correlations lack sufficient precision to help in players’ selection.

Abstract
Physical activity in children and adolescents is on a decline trend. To this end, we conducted a matched-pair randomized controlled trial to examine the effects of a 4-week STAR (School-based; Train-the-trainer; Accessibility of resources; Recreational) skipping programme. 1,386 schoolchildren from 20 primary and secondary schools were recruited. Schools were randomized into the experimental or wait-list control group. Participants self-reported their health-related quality of life using the KIDSCREEN-27. Accelerometers were used to measure the time a subgroup of participants (n = 480) spent in moderate-to-vigorous physical activity during school hours on five consecutive days. Measures were taken at pre- and post-test. At post-test, students in the experimental group, compared to those in the control group, engaged in less moderate-to-vigorous physical activity during school hours. Health-related quality of life from two groups of students was similar, but the experimental group reported higher levels of autonomy and parent relationships. Results suggested that although the intervention did not increase students’ physical activity levels, it slightly improved their health-related quality of life. Future studies should explore personal factors that might mediate the effect of the intervention.

Abstract
Motivation has long been associated with sports engagement. However, to date no research has been performed to understand the domain of motivation among ten-pin bowlers. The purpose of this study was to investigate different types of motivation (i.e., intrinsic vs. extrinsic) based on self-determination theory from the perspective of gender and the bowler type (competitive vs. casual). A total of 240 bowlers (104 male, 136 female; 152 competitive, 88 casual) with a mean age of 16.61 ± 0.78 years were recruited in Kuala Lumpur. The Sport Motivation Scale, a 28-item self-report questionnaire measuring seven subscales (i.e., intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, extrinsic motivation to identify regulation, extrinsic motivation for introjection regulation, extrinsic motivation to external regulation, and amotivation) was administered. Results showed significant differences (t=10.43, df=239, p=0.01) between total scores of intrinsic and extrinsic motivation among tenpin bowlers. There were significant gender differences with respect to intrinsic motivation to know, intrinsic motivation to accomplish, intrinsic motivation to experience stimulation, and extrinsic motivation to identify regulation. However, no significant bowler type differences were found for either the intrinsic (t=-1.15, df=238, p=0.25) or extrinsic (t=-0.51, df=238, p=0.61) motivation dimensions. In conclusion, our study demonstrated substantial intrinsic motivation for gender effects, but no bowler type effects among adolescent ten-pin bowlers.
Proprioceptive ability of fencing and table tennis practioners
Authors: Bańkosz Ziemowit , Szumielewicz Paweł 
Published: May 2015

PurposeThe aim of the study was to compare the spatial component of proprioceptive ability by reproducing a upper limb movement typical in table tennis and fencing.MethodsThe research comprised 41 young males of which 12 were table tennis players, 14 fencers, and 15 not involved in any competitive sports as a control. The experiment was based on assessing the precision of pronation and supination of the forearm at the elbow joint in recreating a set movement range by use of a goniometer.Results and conclusionsThe results point to a higher level of proprioceptive ability in fencers and table tennis players than the control group but only in respect to the tasks executed with the dominant limb. This is inferred to be the result from the specific character of both sports (i.e. the intensive use of one limb and the consequent laterality of that limb) causing higher sensitivity and proprioception. This may provide a link between swordplay, table tennis, and the level of proprioception. The research methodology used herein may be useful in monitoring fencing training. Although not unequivocally statistically significant, the results indicate the potential for further research in this area.

Published: May 2015

Abstract
This paper investigates the effects of firm size, competition and access to finance on the innovation performance of that firm. After a review of the relevant literature, three logit models are proposed and tested. The empirical analysis is based on the business environment and enterprise performance survey (BEEPS) for 1053 enterprises from twenty-six countries in years 2002 and 2005. Our results suggest a positive and statistically significant relationship between firm size and innovation. We also find a positive relationship between both competition and access to finance with innovation.
Semi-Automatic Segmentation of Ct/Mri Images Based on Active Contour Method for 3D Reconstruction of Abdominal Aortic Aneurysms
Authors: Drapikowski Paweł , Domagała Zuzanna 
Published: May 2015

Abstract
Abstract The paper presents a CT/MRI image based semi-automatic AAA (abdominal aortic aneurysm) segmentation method. Segmentation process can run automatically with the active contour method but results are controlled by the operator. If incorrect segmentation is noticed, the operator may introduce corrections. The proposed method makes possible the segmentation of dissected aneurysms, with which no automatic analysis works. Controlling the segmentation process by the operator serves to ensure correct geometric shape reproduction, which is crucial in deploying aneurysm models to help assess rupture risk.
Social Disparities in the Regional Development and Policies of Romania
Authors: Sandu Dumitru 
Published: May 2015

Abstract
This article analyzes the current state of regional disparities in Romania and their dynamics. An index of social development (IDSL) is proposed and computed for each of the communes and cities of the country. The concept basis of that index is given by the notion of community capital with its human, material and vital components. The configuration of social regional disparities results by aggregating IDSL values by counties, communes of the same county, cities of the same county, historical regions and development regions. Regional disparities are analysed, on the one hand, by aggregated values of that index and, on the other hand, by considering the dynamics of GDP per inhabitant, infant mortality rate and life expectancy at birth. The key axes of regional disparities in Romania are related to rural-urban residence, population density, accessibility to service and employment centres, agricultural vs. non-agricultural employment, and network capital of the population. Policy implications of the analysis are introduced by a discussion section at the end of the paper.
Juvenile Sociability, Cultural Classifications and ‘Tastes’: A Study on the Universe of Games and Social Networks in Lower Class LAN Houses
Authors: Barros Carla 
Published: May 2015

Abstract:
The objective of this study is to investigate the appropriation of digital technologies in processes of identity elaboration and sociability in a group of poor urban workers living in Rio de Janeiro, Brazil. The article presents an ethnographic study of LAN houses – the Brazilian cybercafés - focusing on technological uses and their connection with issues such as the role of games as a motor of local sociability and the appropriation of digital technologies as a way of elaborating identities and classifications, through social distinction and cultural tastes. The influence of Internet centers’ attendants was analyzed in connection with the consumption of cultural products such as games and musical styles. The results showed the use of these products in the process of elaboration of local youngsters’ social classifications. The study reveals in what ways game motivation and musical style choices are collectively molded, highlightening the importance of group distinctions and belonging.

Realtime Motion Assessment For Rehabilitation Exercises: Integration Of Kinematic Modeling With Fuzzy Inference
Authors: Zhao Wenbing , Lun Roanna , Espy Deborah D. , Ann Reinthal M. 
Published: May 2015

Abstract
This article describes a novel approach to realtime motion assessment for rehabilitation exercises based on the integration of comprehensive kinematic modeling with fuzzy inference. To facilitate the assessment of all important aspects of a rehabilitation exercise, a kinematic model is developed to capture the essential requirements for static poses, dynamic movements, as well as the invariance that must be observed during an exercise. The kinematic model is expressed in terms of a set of kinematic rules. During the actual execution of a rehabilitation exercise, the similarity between the measured motion data and the model is computed in terms of their distances, which are then used as inputs to a fuzzy interference system to derive the overall quality of the execution. The integrated approach provides both a detailed categorical assessment of the overall execution of the exercise and the degree of adherence to individual kinematic rules.
Parametric Study of the Elementary Segment of an Antiprismatic Pop-Up Deployable Lattice Column
Authors: Friedman Noémi , Farkas György , Ibrahimbegovic Adnan 
Published: May 2015

Abstract
In this article the primary segment of an antiprismatic pop-up mast is analyzed, that can be applied for largely flexible architectural designs, like deployable bridges or transportable look-out towers. This deployable column, consisting of rigid plates, rigid and elastic bars, is characterized by its selfdeploying behavior due to the energy accumulated from lengthening the elastic bars during packing. The main goal of this paper is to prepare the analysis of the complex structure by a herein detailed investigation of the behavior of one, basic element of the deployable mast. After the analytical examination of the general behavior of the basic segment a geometrically nonlinear finite element formulation is used to trace the force-displacement diagram. Besides the parametric study, approximations of main mechanical parameters are herein given for facilitating preliminary design of such deployable structures.
The History of Money in Montenegro
Authors: Fabris Nikola 
Published: May 2015

Abstract
The paper depicts the history of using money in Montenegro covering the period before the Christ until nowadays. Montenegro mostly used foreign currencies throughout its long history, these being Roman, Austro-Hungarian, Turkish, Venetian, and even the Napoleon (French gold coin) money. The first ideas for Montenegro’s own money came from the Bishop Petar Petrovic Njegoš in the 19th century. The first Montenegrin money, the Perper, was minted in 1906. The King Nikola`s Decree as of 11 April 1906 authorized the Ministry of Finance to mint the nickel and bronze coins. Silver and gold coins were minted later. The Perper disappeared from the scene with Montenegro’s joining the Kingdom of Serbs, Croats and Slovenes, putting into circulation the Dinar, a currency of the newly established state. Montenegro, being a part of the Socialist Federal Republic of Yugoslavia, used the Dinar as its currency after World War II until 1999. Dual currency system consisting of the German Mark and the Dinar was introduced in late 1999, whereby the German Mark became the only legal tender in 2001. With the introduction of the Euro the German Mark was replaced and the Euro became the official means of payment.

Published: May 2015

Abstract
A novel methodology is proposed for robust gain-scheduled PID controller design for uncertain LPV systems. The proposed design procedure is based on the parameter-dependent quadratic stability approach. A new uncertain LPV system model has been introduced in this paper. To access the performance quality the approach of a parameter varying guaranteed cost is used which allowed to reach for different working points desired performance. Numerical examples show the benefit of the proposed method.

The aim of this study was to investigate whether powdered plants of different species namely: peppermint Mentha piperita (L.) (Lamiaceae), wormwood Artemisia absinthium (L.) (Asteraceae), common sage Salvia officinalis (L.) (Lamiaceae), allspice Pimenta dioica (Linnaeus et Merrill) (Myrtaceae) and common garlic Allium sativum (L.) (Amaryllidaceae), added to semolina using concentrations of 1.23, 3.61, and 5.88%, influence the mortality rate in the saw-toothed grain beetle Oryzaephilus surinamensis Linnaeus, 1758 (Coleoptera: Silvanidae). Experiments were conducted in a laboratory at 28°C and relative humidity 60±5%. At the concentration of 1.23%, allspice seeds caused the highest mortality amongst the saw-toothed grain beetle. When concentrations of 3.61 and 5.88% were used, sage, peppermint and wormwood caused the highest statistically significant mortality of O. surinamensis
New data on middle and late Albian foraminifera and biostratigraphy of the northern palaeobiogeographical district of western Siberia
Authors: Podobina Vera M. 
Published: May 2015

Abstract
The present paper discusses foraminiferal assemblages and biozones established on the basis of studies of samples from ten borehole sequences of the Khanty-Mansiysk Horizon in the Samotlor area of the northern palaeobiogeographical district of western Siberia (Russia). In this region, middle and late Albian foraminiferal assemblages were first distinguished in western Siberia. Levels from which these assemblages have been recovered, are here referred to the following foraminiferal zones, the Ammobaculites fragmentarius-Gaudryinopsis filiformis Zone (middle Albian) and the Ammotium braunsteini-Verneuilinoides borealis assanoviensis Zone (upper Albian). Zonal assemblages are dominated by representatives of the orders Ammodiscida, Textulariida and Ataxophragmiida. Species of the ataxophragmiid genera Verneuilinoides, Pseudoverneuilina and Gaudryinopsis are the most characteristic, inclusive of several key index forms. Foraminiferal tests consist of agglutinated quartz-silica, the wall microstructure being almost exclusively medium and coarse grained. In specific composition, the Albian assemblages from the Samotlor area are similar to those from Transuralia (Russia) and to the Canadian Province, which, together with West-Siberian Province, forms the Arctic palaeobiogeographical realm
