Authors: Tőkés Gyöngyvér Erika 
Published: February 2020

Abstract
The development of strong service brand confers market advantage under conditions of strong economic competition (Nádasi, 2016). In creating a strong service brand, the first steps include the elaboration of the service brand identity. The goal of this study consisted in applying the socio-scientific-based brand identity model of Burmann et al. (2017) in the analysis of the service brand identities of three Cluj-Napoca-based software and IT companies. The results of the analysis have shed light on the points of parity of the service brand identities of software and IT companies and highlighted the brand identity elements that enable differentiation (points-of-difference). The common points of the service brand identity of the Cluj-Napoca-based software and IT companies consisted in the emphasis on technical competences as well as customer and relationship orientation. Their differentiation was possible along their values and personality, which represent the symbolic benefits of service brand identity. Their symbolic differentiation also resulted in the differentiation of their offers.
Modern Digital Device Systems Supporting the Instruction of Digital Natives
Authors: Molnár György 
Published: February 2020

Abstract
While in our accelerated world everything seems to change, basic values are here to stay. I believe one such aspect is education and training. Although our educational system is built on a relatively permanent basis, instructional methodology on the whole has undergone substantial changes despite that all of the educational system has preserved its role in transmitting, presenting, and preserving knowledge. Since in our fast 21st-century world myriads of facts and fake or questionable information is available, students require new knowledge along with new and perhaps different answers. We believe that education, due to its ability to provide scientifically sound answers to the respective challenges, is vital today. Recent paradigm shifts have led to fundamental alterations in the form of information and knowledge acquisition supported by modern, state-ofthe-art ICT-based methodological solutions and learning environments. The study focuses on the theoretical and practical aspects of such learning support schemes or solutions.
Digital Naïves Go Online

Abstract
We live in a networked world with a fast pace of digitalization, and yet about half of the humanity is still offline (United Nations, 2018). Information and communication technologies are playing a key role in our public and private lives, both during work- and playtime. No wonder that social inequalities are increasingly reflected as digital inequalities in terms of infrastructural access, skills, and cultural practices online: those left behind can hardly keep up. The present research note brings together theoretical and practical resources related to digital inclusion issues globally, with local examples from Romania, where digital naïves – the poor, the rural, the elderly, the disabled, and the less educated – are more at risk.1
Comparison of Morphological Profiles and Performance Variables Between Female Volleyball Players of the First and Second Division In Portugal
Authors: Carvalho Alberto , Roriz Paulo , Duarte Daniel 
Published: February 2020

Abstract
Knowledge of players’ anthropometric profiles may contribute to a better understanding of the differences between their performance levels. For example, vertical jump height, which is a major indicator of a volleyball player’s performance, is influenced by favorable anthropometric variables. This study’s aim was to describe anthropometric profiles of elite female volleyball players competing in the 1st and 2nd divisions in Portugal and to link these profiles with performance skills such as jump height obtained during blocking and spiking actions. Fifty-nine volleyball players were analyzed according to their competitive level, forming three independent groups: GA (n = 20, A1 division, ranked first), GB (n = 21, A1 division, ranked last) and GC (n = 18, A2 division). Anthropometric data collected included body mass and height, arm span, seven skinfolds (triceps, biceps, subscapular, suprailiac, abdominal, thigh and calf), four body perimeters (relaxed brachial, contracted brachial, thigh and calf), and two body diameters (humeral and femoral). Performance data included the height obtained during block and spike actions. Significant differences were found between groups (GA/GB from A1 and GC from A2). Players in the GA had the highest body mass (68.05 ± 6.62 kg, p < 0.05), body height (176.35 ± 6.21 cm, p < 0.05), arm span (177.59 ± 6.09 cm, p < 0.05), lean mass (53.51 ± 4.94 kg, p < 0.05) and vertical jump heights (block: 0.36 ± 0.06 m and spike: 0.43 ± 0.05 m, p < 0.05). As expected, the fat mass percentage of GA players was the lowest (21.30 ± 2.61%). The results suggest that anthropometric profiles of volleyball players may vary according to the competitive level. The higher body mass, body height, arm span, and lean mass presented by GA players in comparison with GC players suggest these variables are important for top-level performance, since these athletes also exhibited higher jump heights. Variables such as height and arm span have a considerable genetic influence and could be important for early talent identification in volleyball. Other variables such as body mass, lean mass and vertical jump performance are more complex, since they also reflect the effects of environmental and training conditions.
A Meta-Analysis on the Effect of Complex Training on Vertical Jump Performance
Authors: Pagaduan Jeffrey , Pojskic Haris 
Published: February 2020

Abstract
Complex training (CT) is a strength training intervention performed by completing all the sets of a resistance exercise followed by a series of high-velocity/plyometric exercise/s. The purpose of this novel study was to conduct a meta-analysis on the effect of CT on vertical jump (VJ) performance. Five electronic databases were searched using terms related to CT and the VJ. Studies needed to include randomized trials comparing CT with traditional resistance training (RT)/plyometric training (PLYO)/control (CON) lasting ≥ 4 weeks and the VJ as a dependent variable. Seven studies qualified for the meta-analysis with two studies differentiating VJ performance from CT and RT, two studies comparing VJ performance of CT and PLYO, and two studies establishing the difference in VJ performance between CT and CON. Results indicated similar improvement in VJ performance from CT and RT (p = 0.88). On the other hand, greater VJ performance in CT than PLYO was identified (ES = 0.86; 95% CI 0.24, 1.47; p = 0.01). CT also showed significantly greater enhancement in VJ compared to CON (ES = 1.14; 95% CI 0.60, 1.68; p < 0.01). In conclusion, CT can serve as alternative training from RT in improving VJ performance. On the other hand, CT is a better option in VJ enhancement than PLYO and CON.

Published: February 2020

Abstract
The purpose of this study was to develop a scale to measure extreme sports participants’ levels of compulsive exercising. There are a number of compulsive exercising scales; however, none of them is targeted for extreme sports participants, whose emotional responses differ from those of non-extreme sports participants. Five hundred extreme sports participants were involved in this study, which included literature analysis, expert review, and exploratory and confirmatory factor analysis. Firstly, 95 items were selected from previous studies related to extreme sports and compulsive exercising. Secondly, nine experts scrutinized the content validity of the 95 items, and 82 items were found to be valid. Thirdly, the 82-item survey was initially administered to 253 participants for the purposes of exploratory factor analysis. Lastly, the 20-item survey that came out as a result of the 82 items being put through the exploratory factor analysis was distributed to the other 247 participants in the confirmatory factor analysis. In the final results, 16 items regarding the four factors of the “withdrawal symptom”, “attachment”, “struggle”, and “obsession” were confirmed. The factors used to measure extreme sports participants’ compulsiveness in this study reflect somewhat different dimensions from those developed in previous studies for non-extreme sports participants or exercisers. Only factors in the affective and behavioral dimensions are included in the present study’s scale, while factors in the cognitive or the combined cognitive, affective, and behavioral dimensions were investigated in previous studies. This explains the need for the present study.

Published: February 2020

Abstract
The purpose of this analysis was to quantify the probability of achieving a top-3 finishing position during 800-m races at a global championship, based on dispersion of the runners during the first and second laps and the difference in split times between laps. Overall race times, intermediate and finishing positions and 400 m split times were obtained for 43 races over 800 m (21 men’s and 22 women’s) comprising 334 individual performances, 128 of which resulted in higher positions (top-3) and 206 the remaining positions. Intermediate and final positions along with times, the dispersion of the runners during the intermediate and final splits (SS1 and SS2), as well as differences between the two split times (Dsplits) were calculated. A logistic regression model was created to determine the influence of these factors in achieving a top-3 position. The final position was most strongly associated with SS2, but also with SS1 and Dsplits. The Global Significance Test showed that the model was significant (p < 0.001) with a predictive ability of 91.08% and an area under the curve coefficient of 0.9598. The values of sensitivity and specificity were 96.8% and 82.5%, respectively. The model demonstrated that SS1, SS2 and Dplits explained the finishing position in the 800-m event in global championships.
Nutritional Recommendations for Physique Athletes

Published: February 2020

Abstract
The popularity of physique sports is increasing, yet there are currently few comprehensive nutritional guidelines for these athletes. Physique sport now encompasses more than just a short phase before competition and offseason guidelines have recently been published. Therefore, the goal of this review is to provide an extensive guide for male and female physique athletes in the contest preparation and recovery period. As optimal protein intake is largely related to one’s skeletal muscle mass, current evidence supports a range of 1.8-2.7 g/kg. Furthermore, as a benefit from having adequate carbohydrate to fuel performance and activity, low-end fat intake during contest preparation of 10-25% of calories allows for what calories remain in the “energy budget” to come from carbohydrate to mitigate the negative impact of energy restriction and weight loss on training performance. For nutrient timing, we recommend consuming four or five protein boluses per day with one consumed near training and one prior to sleep. During competition periods, slower rates of weight loss (≤0.5% of body mass per week) are preferable for attenuating the loss of fat-free mass with the use of intermittent energy restriction strategies, such as diet breaks and refeeds, being possibly beneficial. Additionally, physiological and psychological factors are covered, and potential best-practice guidelines are provided for disordered eating and body image concerns since physique athletes present with higher incidences of these issues, which may be potentially exacerbated by certain traditional physique practices. We also review common peaking practices, and the critical transition to the post-competition period.

Published: February 2020

Abstract
Since there is not enough data about milkability of the Jersey cows, the aim of this paper is to show basic milkability traits of this cattle breed depending on the parity and milk flow curve types. Cows had average daily production (DMY) of 22.23 kg, milk yield per milking (MYM) of 9.72 kg, and average and maximum milk flow about 1.66 and 2.49 kg/min, respectively. Statistical analysis showed that DMY and MYM of the cows in 4th parity was significantly (p<0.05) higher comparing to cows in 1st and 3th parity. The duration of entirely milking is similar regarding the paritiesand only the cows in 3th and 4th differ significantly (p<0.05). Regarding the effect of milk flow curve, the significant (p<0.05) difference between unspecified and rectangular milk flow curve has been found for the average milk flow (AMF) and descending phase of the milk flow curve (TD). Cows with unspecified milk flow curve, have significantly (p<0.05) lower AMF and longer TD compared to cows with rectangular curve. Cows with bimodal milk flow curve have significantly (p<0.05) longer duration of the ascending phase compering to: unspecified, descending and rectangular. The results of this study have shown that Jersey cows have lower production and milk flow compared to other dairy cattle breeds. Nonetheless, they have uniform milkability traits, and a large representation of desirable milk flow curves which are associated with a beneficial effect on the udder health.
The Attempt to Use Levelling Rods for Testing Metric Properties of Surveying Instruments, Which are Used for Reflectorless Distance Measurements
Authors: Świerczyńska Ewa , Kołakowska Maria 
Published: February 2020

Abstract
This paper presents results of two experimental cycles of measurements performed with the use of the terrestrial laser scanner Z+F IMAGER 5006h and the reflectorless tacheometer Leica TPS 1202. These tests aimed at determination of metric properties of surveying instruments, which are used for reflectorless distance measurements and which are often applied to project the geometry of objects. In the course of research works issues influencing the reflection of a laser beam by the measured surface, as well as their influence on the data quality. In order to analyse metric properties of applied instruments, levelling rods were used as test fields of geometrically specified division. It was stated basing on the performed analyses, that the influence of the incidental angle of a laser beam on the accuracy of reflectorless measurements is included within the limits of the error of distance measurements of a given instrument. However, the uniform trend of increasing differences between measured values and the nominal value may be noticed, together with the increase of the incidental angle of the axis of collimation on the measured surface of the test field.
Crazy Sequential Representations of Numbers for Small Bases
Authors: Wylie Tim 
Published: February 2020

Abstract
Throughout history, recreational mathematics has always played a prominent role in advancing research. Following in this tradition, in this paper we extend some recent work with crazy sequential representations of numbers− equations made of sequences of one through nine (or nine through one) that evaluate to a number. All previous work on this type of puzzle has focused only on base ten numbers and whether a solution existed. We generalize this concept and examine how this extends to arbitrary bases, the ranges of possible numbers, the combinatorial challenge of finding the numbers, efficient algorithms, and some interesting patterns across any base. For the analysis, we focus on bases three through ten. Further, we outline several interesting mathematical and algorithmic complexity problems related to this area that have yet to be considered.

Abstract
Here I describe an infinite number of fractal tiles of regular rep-tiles in all dimensions above 1. Each rep-tile’s set of tiles can be divided into subsets based on certain visual characteristics. As fractals, they can be programmed and rendered in any size. They can be arranged in groups according to their aesthetic properties; used as an unending visual and pattern-recognition training ground for AI; and even animated as increments from one to the next.
The Classification of Primitive-Shaped Patterns by Using Principal Component Analysis Method
Authors: Widagda IGA , Suyanto Hery 
Published: February 2020

Abstrak – The recognition or classification of patterns is a major problem in computer vision. Many methods have been applied such as: moment invariant, Artificial Neural Networks (ANN), K-mean, Support Vector Machine (SVM) and others. These methods have a few limitations. The moment invariant fashion is highly vulnerable to noise. ANN methods require a long computing time (especially multi-layer ANN) during the training process. On the other hand, the dimensions of the features generated from the methods are relatively high, which requires large storage space (memory). In addition, this leads to the long computing time when the testing process is carried out. Based on these facts, this research makes use of methods that being able to reduce the feature dimensions, namely the Principal Component Analysis (PCA). In the PCA method the dimensions of the sample image are converted to principal components (face space), whose dimensions are much smaller than the dimensions of the sample image itself. Our works exhibit that the PCA method is highly effective in carrying out the pattern classification process. This can be indicated by the relatively high values of Predictive Accuracy, Precision and Recall (close to 1) while the FP Rate is low (close to 0). Moreover, the location of the point coordinates (FP Rate, TP Rate) in ROC graphs is fallen in the upper left region (approaching the perfect classifier region).
