Accessible tourism is an under-researched area in Hungary. Based on the results of a questionnaire survey, the aim of the present study is to present several specific features of the travel demand of people with disabilities, the foremost focus being the examination of the most popular tourism products in the demand of people with disabilities. 268 Hungarians responded to the survey in online and face-to-face contexts. In addition to the Hungarian survey, the article also covers small-sample research results from four other countries (Germany, Italy, Spain and Croatia). The results show that members of the target group reject segregation solutions during their travels, and, as opposed to integration, clearly demand inclusion. Their travel frequency is above average of the entire population, with interests as diverse as those without disabilities. The issue of accessible tourism affects 10% of the European population, and thus, besides the significance of the issue from a social and societal point of view, this segment cannot be neglected in terms of its market value either. Understanding the expectations of stakeholders and their specific consumer habits is an essential requirement in the development of appropriate tourism supply and in ensuring equal access to services.

English as a foreign language (EFL) university students use reflective journals as learning logs to express or capture their ideas within a scientific conceptual framework. The objectives of this research are to (1) describe the power of reflective journal writing in communicating ideas, and (2) identify the aspects of reflective journal writing that aid learning in an EFL context. The reflective journals were written by 21 EFL university students. This research takes a qualitative approach, with the primary data coming from several reflective journals (N=124) while the secondary data coming from EFL students’ interviews (N=15). The research results showed that reflective journals were useful for students to make critical reflections and self-discovery responses to writing topics. The students learned to focus on writing components such as order, unity, coherence, cohesiveness, content, and organization of ideas through reflective journal writing. The students’ perspectives on aspects of reflective journal writing were primarily concerned with macro-and micro-level linguistic issues, as evidenced from the interview results. Writing a reflective journal necessitated their ability to reformulate thoughts, provide details, and solve problems. Furthermore, critical thinking, metacognitive skills, and self-reflections became increasingly important in helping the students to develop their ability to write reflective journals.

This study was conducted for two seasons from 2018 to 2020 to determine fenugreek genotypes yield and quality characteristics under semiarid climatic conditions. Fenugreek genotypes viz., Adana, Afghanistan, Gaziantep, Iraq, Kahramanmaraş, Kayseri, Mardin, Şanlıurfa with varieties of Berkem and Gürarslan were used as plant material in the research. Field trials were conducted with four replications according to the randomized complete block design. The results revealed that the time to emergence varied from 16.0 to 19.9 days, 50% flowering from 160.9 to 170.4 days, and the vegetation period from 202.0 to 209.3 days. According to the results of two years of research, plant height varied from 64.60 to 78.70 cm, first pod height from 25.26 to 41.76 cm, pod width from 2.91 to 3.29 mm, pod length from 10.07 to 12.60 cm, number of pods per plant from 12.00 to 18.73, number of seeds per pod from 12.55 to 15.55, biological yield from 5.12 to 7.62 t/ha−1, seed yield from 0.91 to 1.38 t/ha−1, harvest index from 17.91 to 24.35%, thousand-seed weight from 13.87 to 17.45 g, fatty oil content from 5.18 to 9.16%, fatty oil yield from 49.3 to 111.6 kg ha−1, and the trigonelline ratio varied from 0.71 to 1.32%. Statistically significant differences (p ≤ 0.05) were observed for the pod width, while highly significant differences (p ≤ 0.01) were observed for all other parameters. According to the research results, Mardin, Kayseri, and Adana genotypes were statistically in the same group with Berkem cultivar in terms of seed yield. A higher fatty oil content was obtained in the Afghanistan genotype (9.16%) than in the Berkem cultivar (8.11%). Gaziantep, Mardin, Şanlıurfa, and Kayseri genotypes contained higher trigonellin than the Berkem and Gürarslan varieties. The obtained information was the result of the Mardin, Kayseri, Adana, Gaziantep, and Afghanistan genotypes that can be used in breeding studies.

Academic journals and discipline construction in colleges are two major drivers of scientific progress. There is a complex interactive mechanism between the two drivers. The synergy between the two is worthy of in-depth research. The research aims include better developing academic journals with discipline advantages and back-feeding discipline construction with academic journals. The symbiotic theory provides a new research perspective for the cooperation mechanism between college academic journals and discipline construction. Drawing on the symbiotic theory, this paper explores the root causes and interactive logic of the collaboration between college academic journals and discipline construction, from the angles of the symbiotic unit, symbiotic environment, and symbiotic model. The results show that the symbiosis between academic journals and discipline construction in Chinese colleges mainly relies on two essential parameters, namely, academic talents and research results; although colleges provide a positive environment, the symbiosis between the two factors mostly takes place on unofficial information platforms and cooperation mechanisms, for the relevant policies are relatively new and mostly discipline-oriented; the symbiosis between college academic journals and discipline construction is mutualistic but remains in the intermittent stage. Therefore, it is important to find a more effective symbiotic path for college academic journals and discipline construction, following their symbiotic law.

AbstractAiming at the problem of severe vibration and abnormal wear and tear of various components in coal shearer under slant-cutting conditions, a non-linear dynamics model with 13 degrees of freedom for a coal shearer under slant-cutting conditions is developed using vibration mechanics and multi-body dynamics theory, and the characteristics of the slide shoes-middle groove contact, the ranging arm-haulage unit connection with gaps and the guidance sliding boots-pin rail multi-surface contact with gaps are described based on three-dimensional fractal theory and Hertz contact theory. Based on Huco's law, the ranging arm and the hydraulic rod are assumed to be flexible beams, the rigidity characteristics of the ranging arm itself, the connection characteristics of the haulage unit and the fuselage are described, a drum correction load with a traction speed correction factor is proposed as the external excitation of the system, and the model is solved and analyzed. The research results show that the change of traction speed has a greater influence on the vibration swing angle and displacement of the front drum, front ranging arm and front walking unit, and the vibration swing angle and displacement of the three increase with the increase of traction speed, while the change of coalface hardness coefficient has less influence on the vibration displacement of the key components of the coal shearer. Under the working parameters of v = 3 m/min and f = 3, the swing angle and displacement of the front ranging arm and front drum fluctuate in the ranges of − 0.4–0.1 rad and – 15–15 mm respectively; the vibration acceleration is – 300–300 rad/s2 and – 200–200 mm/s2 respectively, the main vibration frequencies are 16.63 Hz and 12.14 Hz respectively, and finally the results are verified by experimental methods.

During the COVID-19 pandemic, livestream shopping has provided consumers with a way to maintain social distancing while offering an alternative to offline shopping. This study aims to understand the impact of COVID-19 and other public health crises on the behavioral intentions of consumers using livestream shopping technology. A theoretical model was designed that combines the health belief model, trust theory, and the theory of planned behavior. Empirical data were collected from 358 residents in China and then analyzed using structural equation modeling. The results showed that perceived susceptibility, perceived severity, perceived benefits, and perceived obstacles had a significant impact on consumer trust. Consumer trust in turn had a direct impact on behavioral intention and an indirect impact on behavioral intention via attitude. These research results have practical implications for livestream shopping merchants, platform decision-makers, and service designers.

Abstract Background. This scoping review aims to analyse the literature on community based participatory research (CBPR) -based cardio vascular disease (CVD) management programmes, examining the key elements of their development and implementation and exploring their effectiveness. Methods. This study is based on the scoping review methodology, consisted of six stages: 1) identifying the research question; 2) identifying relevant studies—search strategy; 3) study selection; 4) charting the data; 5) collating, summarising, and reporting the results; and 6) consultation exercise. The electronic databases used for the literature search were PubMed, Cochrane, and CINAHL. The search period was from 4 March to 3 April 2020. We selected studies that: 1) were published after 2000; 2) targeted community residents over the age of 18; and 3) proposed a CBPR-based CVD management programme, described its development process, or evaluated its effects based on its application. The data were extracted independently by two researchers according to the standardised form. Results. Among the key elements of such programmes, there were many cases in which community organisations played the leading role in establishing partnerships and cases in which a decision-making committee was formed. Regarding the application of the CBPR principles, community partners participated only in executing the research and not in the process of analyzing and interpreting research results. In addition, In all six RCT studies, the experimental groups showed significantly positive effects compared to the control groups. Conclusion. It is necessary to develop strategies to improve the criteria based on which CBPR principles cannot be implemented during the development and implementation of a CBPR-based CVD management programme. In addition, more attempts to verify the effectiveness of high-quality research methodology should be made when evaluating the effectiveness of programmes.

ABSTRACT This article introduces how to teach an interactive, one-semester-long statistics and programming class. The setting also can be applied to shorter and longer classes as well as introductory and advanced courses. I propose a project-based seminar that also encompasses elements of an inverted classroom. As a result of this combination, the seminar supports students’ learning progress and also creates engaging virtual classes. To demonstrate how to apply a project-based seminar setting to teaching statistics and programming classes, I use an introductory class to data wrangling and management with the statistical software program R. Students are guided through a typical data science workflow that requires data management and data wrangling and concludes with visualizing and presenting first research results during a simulated mini-conference.

This work is devoted to the development of a new simplified method for express diagnostics of cerebral blood supply disorders of a vertebrogenic and non-vertebral nature based on electrocardiogram and photoplethysmogram data. The research was conducted using the example of vertebral artery syndrome in osteochondrosis of the cervical spine and somatoform dysfunction of the autonomic nervous system, respectively. Several experimental studies into the dynamics of heart rate variability and differential indicators of the coordinated work of the heart and blood vessels were carried out according to the data of electrocardiography and photoplethysmography. Three experimental groups included healthy volunteers and volunteers with cerebral blood supply disorders connected with either the loss of plasticity and narrowing of brain blood vessels or their mechanical squeezing. According to the research results, statistically significant (with a significance level of less than 0.05) differences by a number of indicators were revealed between the experimental groups. A conventional discriminant analysis of the indicators of the coordinated work of the heart and blood vessels was carried out for all experimental groups in order to determine criteria for differentiating people with vertebrogenic disorders, non-vertebral disorders and healthy volunteers. It is concluded that three variables can be used for such differentiation, each of which describes the coordinated work of the heart and blood vessels in a specific way.
