Due to the process of globalization, travel has become much more affordable, so tourists have the opportunity to visit foreign and even some exotic destinations. Market research helps travel agencies in formulating a marketing strategy, which should attract tourists and ensure their satisfaction, which ultimately enables the service provider to make a profit. The purpose and goal of the research is to determine whether cultural intelligence as a push-factor implying the desire of tourists to learn a foreign language, and get to know other cultures and their value systems and cultural heritage as a pull-factor implying touring buildings, and cultural monuments of other countries, influence the choice of foreign tourist destinations. Furthermore, the research examines whether the influence of these variables from the aspect of a demographic characteristic of age is more pronounced in respondents belong to generation Z compared to the generation X respondents. The sample includes 208 respondents from the Republic of Serbia. After statistical processing of the data, the obtained results show that variables have a statistically significant positive impact on the choice of foreign tourist destinations, and that their impact is more pronounced in generation Z respondents compared to those of generation X, so the research provides useful information to marketers and travel agencies.

Teaching Function

The consideration of function is prevalent across numerous domains as a technique allowing complex problems to be abstracted into a form more readily solvable. In engineering design, functional models tend to be of a more generalized nature describing what a system should do based on customer needs, target specifications, objectives, and constraints. While the value of function in engineering design seems to be generally recognized, it remains a difficult concept to teach to engineering design students. In this paper, a study on the effectiveness of an algorithmic approach for teaching function and functional model generation is presented. This paper is a follow-up on to the 2012 ASME IDETC paper, An Algorithmic Approach to Teaching Functionality. This algorithmic approach uses a series of grammar rules to assemble function chains which then can be aggregated into a complete functional model. In this paper, the results of a study using the algorithmic approach at Texas A&M in a graduate level design course are presented. The analysis of the results is discussed, and the preliminary evidence shows promise toward supporting our hypothesis that the algorithmic approach has a positive impact on student learning.

Training Load

Estudos demonstraram que as variações periódicas na carga de treinamento de força são mais eficientes para promover força muscular em comparação a treinamentos que não variam a carga ao longo do tempo. Essa variação ocorre pela manipulação das variáveis de um programa de treinamento, como a intensidade, volume, velocidade das ações musculares e ordem dos exercícios. Embora as evidências apontem a superioridade do treinamento variado, não está claro como os processos que influenciam a produção de força são afetados quando o treinamento é realizado com variação de carga. Conhecer os mecanismos desencadeados pela variação da carga ao longo do tempo pode levar a treinamentos mais específicos aos objetivos desejados. Assim, objetivamos discutir os mecanismos centrais e periféricos que influenciam o processo de produção de força e gerar insights para novas investigações que visem comparar o desenvolvimento da força entre os variados e não variados programas de treinamento de força.

Background: The effects of flywheel resistance training (FRT) on youth are relatively unknown. The aim of this study was to compare the effects of autoregulated FRT with traditional strength training (TST) on jumping, running performance and resistance training load progression in youth athletes. Thirty youth athletes (11.8 ± 0.9 yr) were matched for peak height velocity (PHV) status and block-randomised into two groups: FRT (n = 15, PHV −0.8 ± 1.6) and TST (n = 15, PHV −0.8 ± 1.5). Twelve resistance training sessions over a six-week intervention with flywheel or barbell squats were performed using autoregulated load prescription. Squat jump (SJ); countermovement jump (CMJ); and 10 m, 20 m and 30 m sprints were assessed pre- and post-intervention. The external load increased similarly for FRT and TST (z = 3.8, p = 0.06). SJ increased for both groups (p < 0.05) but running performance was unaffected (p > 0.05). Conclusions: FRT resulted in similar load progression and motor skill development in youth athletes as TST, but the perceived exertion was less. Autoregulation is a practical method for adjusting training load during FRT and should be considered as an alternative to autoregulated TST.

Deep knowledge of current English vocabulary is an essential quality of a competent expert in the field of IT. Various technologies of development of lexical competence are based on the indisputable statement  – lexical units (words and phrases) for students to study should be arranged according to their relevance in the daily communication in English. Objective quantitative indicators of relevance of lexical units in everyday life situations are presented in frequency dictionaries; however, their role in the process of professionally oriented foreign language teaching has not been sufficiently studied.The purposeof the research is to increase the efficiency of the process of development of the English language lexical competence of students in IT fields by supporting and actively using electronic frequency dictionaries as additional means of the vocabulary expansion.Materials and methodsof research include the analysis of the problem of development of the English language lexical competence of students of IT directions, modeling of the process of work with frequency dictionaries in the learning process, the practical implementation of the developed model, the pedagogical experiment and analysis of its results. The vocabulary is rapidly updated in the field of IT, for these reasons, in the process of development of the lexical competence of IT students it was decided to maintain their own frequency dictionaries of actual computer vocabulary, extracted from a wide range of the English language texts in IT sphere. The article presents a structural and functional model of working with frequency dictionaries in the learning process that is a sequence of three important steps to be performed by the lecturer, and the results of each of them. Such steps are the formation of the collections of relevant texts on it, computer processing of these collections to build frequency dictionaries and automatic and manual editing of the dictionaries, intended for the formation of the ordered list of lexical units for students to learn.The result of the researchis the practical implementation of the presented model of work with frequency dictionaries. The most labor-intensive and responsible job is the preparation of the collection of English texts, based on the well-established interdisciplinary interaction. Building a frequency dictionary from the collection is performed by standard means of Microsoft Office. The editing of this dictionary means automatic and manual removal of lexical units that are of no worth for students in terms of their vocabulary expansion. The article also presents the results of a successful pedagogical experiment on the development of students’ lexical competence in the process of their preparation for the World Programming Championship. During the training, the participants with the help of such frequency dictionary quickly improved their knowledge of the vocabulary necessary to understand the conditions of the programming assignments in English.At present, the model of work with frequency dictionaries presented in the article has proved its usefulness and positive impact on the development of lexical competence. The frequency dictionaries obtained in the course of study are regularly updated and actively used in the learning process as a good supporting tool without replacing well-tested learning technologies proven to be effective, but supplementing this process.

PURPOSE: This study tested the hypothesis that previous strength training episodes favorably contribute to muscular hypertrophic adaptations in rat soleus muscle after long-term detraining and retraining in rats.METHODS: Female Sprague-Dawley rats (n=24) aged 8 weeks were randomly assigned to four groups: control (CON), detraining (DT), strength training (ST), and retraining (RT). The strength training was a regular bout of ladder climbing exercise that consisted of three sets of five repetitions and three days per week for eight weeks. A cylinder containing weights was loaded to the bottom of each rat’s tail. The weights carried during each training session were initially 50% of body weight and progressively increased by 10% per session. Rats in the DT underwent twenty weeks of detraining periods immediately after eight weeks of strength training. Rats in the ST were aged matched to the RT group and underwent eight weeks of strength training at the same duration with the RT group. Rats in the RT were conducted to the resistance training for eight weeks following the detraining period. Soleus muscles were collected at the end of the training episodes to examine alterations in cross-sectional area and protein contents.RESULTS: ST showed a significant increase in cross-sectional area of the rat soleus muscle, compared with CON. It was interestingly demonstrated that RT markedly elicited hypertrophy of soleus muscle, compared with all other groups. It was supported that RTinduced hypertrophy was related to increased myofibrillar protein contents of the soleus muscle.CONCLUSIONS: These results suggest that although prolonged training cessation occurs previous strength training episodes have a positive impact on restoring muscular contractile properties and hypertrophy after retraining.

ABSTRACT Introduction: The success of training depends on the balance between training load magnitude and recovery. Objective: Verify the effect of training load distribution on recovery status, vigor and fatigue in volleyball players during a season. Methods: Nine male athletes from a professional volleyball team participated in the study. During 19 weeks of the season, quantification of the training load was performed through the session rating of perceived exertion (RPE) method, evaluation of the athletes' recovery status through the Total Quality Recovery (TQR) scale, and evaluation of the profile of mood state through the POMS questionnaire, with research focus for the subscales vigor and fatigue. Results: The average total weekly training load (TWTL) was 3206 ± 685.5 A. Us and the average recovery of the whole season was 15.3 ± 0.57. The mean values of fatigue and vigor were 11 ± 3.05 and 19.4 ± 2.84, respectively. Significant differences were found for the variables RPE, fatigue and Energy Index (Vigor - Fatigue) in the three different periods of the season (Preparatory Period, Competitive Period I and Competitive Period II). Conclusion: It was concluded that the training load and recovery monitoring methods used throughout the season were effective in controlling the variables, with a positive impact of training loads verified on the recovery values presented by the athletes. Level of Evidence III; Diagnostic study.
