Full textAbstract:
There is an emerging confusion in scientific literature between reflexivity and self-reflectivity. Self-reflectivity is a self-awareness of oneself own conduct to self-regulate feelings, thinking and action to reproduce acceptable social norms such as professional and socially best practices as citizens. Rather, reflexivity emerging literature refers to a metaconscious critical intellectual process and experiential transforming feelings, thinking and action to create new knowledge, innovate new actions and even improve resilience capability. This research argues that knowing how to do reflexivity will it as a transformative force enabling human development. The research question is: How to apply Reflexibility for Knowledge Development, Innovation and Resilience and what are the benefits? To answer this question a 17 year-long (2005-2022) experimental phenomenological action research was conducted. Findings reveal how reflexivity can be applied to one’s life experience, but also to knowledge, beliefs and values reaching ideological and social norms critical awareness enabling knowledge development and innovating new actions as an ability to practice resilience. The discussion addresses the long-term benefits of practicing reflexivity applied on knowledge and innovation building empowerment and resilience capability.

Full textAbstract:
With the development of intelligent technology, it is of great significance to develop intelligent equipment with topography self-sensing function. The micro morphology perception technology applied to intelligent equipment is the key technology for development. In this paper, at first, topography perception theory based on the PVDF (Polyvinylidene Fluoride) technology is researched, then an experimental study is conducted to sense the characteristic points of the geometric curve of the preset topography surface used in the PVDF film, and then the Ferguson curve model is used to reconstruct the topography characteristic curve. The experimental results show that the reconstruction curve can truly reflect the features of the characteristic curve of the surface of the preset topography, and the feasibility of topography surface sensing technology by PVDF sensing technology is verified. The research provides technical support for the development of intelligent equipment with topography self-sensing function.

Full textAbstract:
The development of high-throughput sequencing (next-generation sequencing technology (NGS)) and the continuous increase in experimental throughput require the upstream sample processing steps of NGS to be as simple as possible to improve the efficiency of the entire NGS process. The transposition system has fast “cut and paste” and “copy and paste” functions, and has been innovatively applied to the NGS field. For example, the Assay for Transposase-Accessible Chromatin with high throughput sequencing (ATAC-Seq) uses high-throughput sequencing to detect chromatin regions accessible by Tn5 transposase. Linear Amplification via Transposon Insertion (LIANTI) uses Tn5 transposase for linear amplification, haploid typing, and structural variation detection. Not only is it efficient and simple, it effectively shortens the time for NGS sample library construction, realizes large-scale and rapid sequencing, improves sequencing resolution, and can be flexibly modified for more technological innovation.

Full textAbstract:
Several kinds of research conclude that the level of digital competence of students is mainly oriented to their daily activities. Therefore, we present the current paper which seeks to determine the impact of implementing a blended learning course designed to improve digital competence for research (DCR) among a group of undergraduate engineering students. With this approach, a quasi-experimental explanatory methodology with a causal-comparative scope was applied. For this reason, the results were analyzed before and after applying a specially designed course to the experimental group, comparing it with a passive control group by collecting data using three previously validated instruments. For data analysis, students’ t-tests and two-way ANOVA (Analysis of Variance) were used, estimating the effects with Cohen’s study. Given the results, there was a statistically significant improvement (p ≤ 0.05) in their skills and attitudes, but not in their knowledge, obtaining a significant effect size only in the procedural dimension (f = 0.41 y η2 = 0.142). Therefore, the implementation of the course used in the blended learning modality is considered to significantly improve the DCR of a group of undergraduate engineering students, although the results should be evaluated with due reservations.

Full textAbstract:
Dynamic failure of brittle materials is a rather complex issue. In this paper, experimental work was carried out for plaster model, to study the crack development features of brittle materials under the action of explosion. It shows that couple medium has great influences on detonation wave type. The water has the cushioning effect on detonation wave, which makes the wave crest truncated and results in low wave amplitude and large wave width. Detonation wave type has apparent influence on failure features of brittle materials, of which larger wave width would keep the wall of exploded hole intact and increase the development length of cracks. The research results would be applied to coal mining to increase the efficiency of gas pumping drainage.

The packaging industry is one of the most important sectors of the economy, recognized and diagnosed as strategic for society. With this, technologies have arisen aiming at sustainable development and the search for materials that minimize damages to the environment. At the same time, the need for innovation, quality assurance and practicality to be offered to the consumer, there is concern about its final destination in an economical and environmentally correct way. Included in this context are the cellulosic packaging and the substitution of coatings based on synthetic polymers by natural polymers. In the present work, coatings based on the chitosan biopolymer were developed with the addition of natural dyes: anthocyanin and urucum (Bixa Orellana L.), entitled PCA2 and PCU2, respectively. Samples of paper (277 g/m2) were coated and characterized as Scanning Electron Microscopy (SEM), thickness, weight and barrier properties: WVPR, COBB and tensile strength. Weight and tensile strength analyzes showed no statistical differences. There was a reduction of WVPR of the order of 38.6% and 24.2% for the PCA2 and PCU2 samples, respectively, when compared to uncoated samples (PU). Similar fact occurred with the COBB analysis, there was reduction of the order of 14.8% and 29.62%.

Full textAbstract:
The development of research abilities is a necessary competency for students of Engineering and Science. Regardless of the engineering field of interest, the development of global competencies influences their professional performance. In the present work, we describe the impact, from the students' perception, of the early approach in research activities that involves critical thinking, innovation, problem-solving, self-direction, leading, and written communication abilities. To introduce the students to Research-Based Learning (RBL), we asked them to develop a solution to a problem presented in a first-semester science class in a university focused on developing technical and transversal competencies. This work proposes a teaching methodology based on RBL, which includes the appropriate use of search tools, data analysis, and writing skills, taking advantage of the institution's resources. Simultaneously, we looked for an effective research methodology to build a solid theoretical framework relevant to their experimental results. Moreover, we aimed to link the theoretical course contents to the student's engineering field through RBL activities. The sample under study had 98 students taking an experimental physics and statistical analysis course; 49 in an experimental group (class) were guided using RBL, and the other students were in the control group. The evaluation of the learning outcomes was carried out comparing the pre-and-post surveys, using a 5-point Likert scale (ranging from strongly disagree to strongly agree). The statistical analysis of the experimental guided group results showed an increase in critical thinking, innovation, problem-solving, and self-direction compared to the control group students. However, the leadership competency did not show any improvement in both groups. We concluded that implementing the RBL methodology for students in the early stages of engineering education promoted and reinforced the development of technical and transversal competencies

Full textAbstract:
Though hundreds of journal pages have been packed with studies describing, analyzing, and synthesizing benefits of PBL over conventional curricula we still don’t really know why because there are so many differences between them that it is impossible to say which of the various elements contributes to any incremental student learning. We need to apply the scientific method to studies of curriculum delivery. Accumulating evidence from strong studies in messy real-world situations will eventually yield important insights and instrumental truths for real medical schools and real medical students that teachers and administrators can then implement. Examples of feasible experimental designs are described including a factorial study. More effective curriculum development is only possible through a renewed applied research agenda that is both focused and grounded in the real world.

The paper highlights the difficulties of functioning in multi-parameter systems due to the diverse nature of their link connections. The paper examines a specific case of an «operator-machine-animal» biotechnological system employed in the context of machine milking operations. The system includes three subsystems: two of them have a biological nature and exhibit probabilistic behavior, while the milking machine, serving as a connecting element with inanimate characteristics, is to be regarded as a deterministic technical subsystem. (Research purpose) The research aims to substantiate the conceptual approach to the functioning of an «operator-machine-animal» biotechnical system, taking into account the subsystem interaction patterns. (Materials and methods) The paper explores the conditions governing the operation of biotechnical systems characterized by inherent randomness (in the probabilistic-statistical sense). It was determined that the operation of such a system is influenced by a significantly greater number of factors compared to the «man-machine» system. The biotechnical system as a whole remains stochastic, while its control algorithms maintain a probabilistic nature. The study was conducted by assessing the results obtained through statistical analysis of experimental data, employing methods and techniques of mathematical modeling for technological processes, and exploring key avenues for the development of intelligent digital technologies. (Results and discussion) The utilization of adaptive control principles ensures a high probability of successfully attaining the ultimate objectives. A model for an «operator-machine-animal» system functioning has been developed. The rationale for the efficacy of the interaction between the «machine» and «animal» subsystems is illustrated through the case study of the DeLaval™ DelPro MU480 linear milking machine. A block scheme for the «operator-machine» control system was developed. The performance of the machine milking operator was assessed. A mathematical model detailing the operator's errors was outlined. Criteria for ensuring the operational reliability of the «operator-machine» system were introduced. (Conclusions) The efficiency of a multiply connected biotechnical system is constrained by the zone of maximum adaptation. A mathematical model is provided to describe the functioning of a machine milking operator. The professional stability of an operator, acting as an adaptive and stochastic component, depends on individual attributes and working conditions that need statistical evaluation. The adaptation concept is indicated as a promising area of research. Engineering decisions about the cow milking process are to be based on practical insights into animal ethology, formalized through logical-linguistic models.

In this study, a granular material (GM) derived from wastes generated in waste-to-energy plants was developed. Weathered bottom ash (WBA) and air pollution control (APC) ashes obtained from municipal solid waste incineration (MSWI) were used as raw materials. A mortar (M) with 50 wt. % of APC and 50 wt. % of Ordinary Portland Cement (OPC) CEM-I was prepared. The GM formulation was 20 wt. % M and 80 wt. % WBA. At the laboratory scale, WBA, APC, M, and crushed GM were evaluated by means of dynamic leaching (EN 12457-4) tests, and WBA, M, and crushed GM by percolation column (CEN/TS 16637) tests. The metal(loid)s analyzed were below the non-hazardous limits, regarding the requirement of the metal(loid)s released for waste revalorization. In order to simulate a road subbase real scenario, the crushed GM was tested in an experimental section (10 × 20 × 0.2 m). During a 600-day period, the leachates generated by the percolation of rainwater were collected. This research shows outstanding results regarding the metal(loid)s released for both the “accumulated” and “punctual” leachates collected. An accomplishment in the immobilization of metal(loid)s from APC residues was achieved because of the encapsulation effect of the cement. The GM formulation from both MSWI wastes can be considered an environmentally safe procedure for revalorizing APC residues.

Despite good intentions, academic research often reflects an extractive model and is not always seen as useful within the Canadian arts sector. Mass Culture is a non-profit organization that aims to bring together cultural workers and academics in support of collaborative research and better knowledge mobilization. To that end, their Research in Residence (RinR) initiative involved complex collaborations between the arts sector and academia to explore five applied research projects on a topic of shared importance to participants - that is, articulating the value of the arts through qualitative rather than quantitative measurements. To learn from the experimental research design, participants conducted a developmental evaluation with five lines of inquiry: benefits and effects, program design adaptations, values alignment, efficacy and potential, and knowledge mobilization and research engagement. The evaluation had three purposes: (1) to gather data and facilitate analysis of the key questions that the initiative was trying to understand; (2) to inform Mass Culture's implementation and adaptation of the initiative; and (3) to generate insights on principles and practices that could inform the design of future initiatives. This article considers the second and third purposes, outlining key lessons learned that shaped the initiative and/or should inform future projects.

Full textAbstract:
Recent research has been developed by different groups towards the development of sonic crystals as noise barriers. The present paper aims to contribute to this research, focusing on the possible application of this technology in practice, and exploring some aspects that may be useful for its further development. One of the objectives of this work is to explore the differences between experimental results obtained under laboratory conditions and numerical results computed with the finite element method (FEM), in 2D and 3D, understanding if different types of simplified models can be of use in the practical analysis of sonic crystals. Through this comparison, a validation of the prediction numerical models is performed, giving confidence for their use in the development and study of sonic crystal configurations. In this context, different geometric arrangements of the sonic crystals’ scatterers (the individual elements that make up the barriers) have been analyzed with the help of the numerical method, evaluating their behavior in different arrangements of numbers of elements, shape and size. A number of parametric studies are also performed introducing some randomness in the structure (in scatterer size and spacing), and analyzing its effect on the insertion loss provided by the sonic crystal. These contributions can be significantly useful for the development of new solutions, giving important hints about the sensitivity of these structures to possible defects or limitations in their production.

Full textAbstract:
188 Background: Irreversible electroporation (IRE) is a promising novel technique for the ablation of tumors. An advantage of IRE is its mechanism to remove undesired cells by affecting the cell membrane without thermally destructing blood vessels, nerves and the surrounding tissues. Several clinical trials for applying IRE to human organs such as liver, pancreas, and kidney are conducted and studies about IRE ablation for gastrointestinal tumors also have been conducted recently. Here, we developed new endoscopic IRE device, and studied about its effectiveness and feasibility in animal model. Methods: Newly developed endoscopic IRE ablative catheter works with single channel of endoscope. A pair of dipolar electrodes consist of pre-shaped f 0.63mm nitinol wire and the distance between each electrode is 10 mm. The electrodes are loaded within braided tube for stent delivery system then deployed when IRE catheter put in stomach through the endoscope. We performed endoscopy and IRE ablation was done on pig’s stomach mucosa by using endoscopy with newly developed IRE catheter. We divided pig’s stomach into 2 parts(antrum & body), and IRE ablation was applied on each part of the stomach. Pigs were sacrificed after 24hours, and we collected their stomachs with surgical technique. Following fixation, tissues were stained with H&E. Results: Ten male Yorkshire pigs and in vitro stomachs were used in this study. The tissue with H&E stain showed diffuse cell death 24hr after IRE ablation. Consistent with the mechanism of action of IRE on the cell membrane only, there was complete cell death within the IRE lesions without intervening live cells. But there was no difference in histology depending on gastric part in which ablation was applied. During the study, no complication was observed in pigs in 24 hours after ablation. Conclusions: The new endoscopic IRE device, which can perform IRE ablation on gastrointestinal tract using endoscopy showed safe and feasible result.

Contact antimicrobial coatings have been a subject of increasing interest partly because of the contribution of biocide release coatings to antibiotic resistance. The surface hydrophobicity of these coatings can enhance their effectiveness and stability. In this work, polyethyleneimine (PEI) was quaternized with 1-bromoalkane and iodomethane, and a concept for antimicrobial coatings was developed on the basis of the polyelectrolyte multilayered films. The multilayered films were endowed with antibacterial property by grafting modified polycation (higher charge density) and with fouling-release property by constructing microstructures and nanostructures with low surface energy (long alkyl chains). The resultant polycation-coated substrates were able to kill the encountered bacterial cells on contact, and to release the dead bacteria and organic particles. The conclusion demonstrated that the microbicidal functionality could be imparted onto surfaces using layer-by-layer (LbL) self-assembly technology by using the right combination of molecular technologies and surface nanostructures, as well as the assembly and/or post-assembly experimental technical factors.

Full textAbstract:
The article shows that the temperature of urban soils is one of the main indicators of their condition. The average value and the nature of the temperature distribution in the soil volume determine the processes of heat transfer between the soil and the air in the urbanized area. This ultimately characterizes the influence of urban soils on the processes of climate formation in urban areas. The analysis of modern methods for studying the temperature dynamics of urban soils is carried out. It was found that research is rational to carry out by combining theoretical and experimental methods. The dis-tribution of temperature fields and heat flux density fields in urban soils under various conditions is deter-mined by mathematical, in particular, numerical methods. Coefficients of thermophysical properties of the soil, as well as verification of some calculated results, are carried out by experimental methods. An analysis of existing experimental research methods revealed a key drawback: a small number of points for simultane-ous temperature measurement in the urban soils volume. A scheme is proposed, as well as a prototype of a means of automated control of the distribution of the temperature field, which allows us to study the tempera-ture dynamics at various depths of the soil profile. To test the means of automated control, comparative studies of the dynamics of the temperature field in the volume of urban soil represented by gray forest soil were carried out. An experimental temperature dis-tribution was obtained over several days; a statistical verification of the results was carried out. Theoretical calculations of the dynamics of the temperature field by the numerical model J.A. Infante Sedano It is estab-lished that the discrepancies between the theoretically predicted and the experimentally estimated tempera-ture field are insignificant, which allows us to use the developed tool for automated control of the tempera-ture field distribution in the soil to assess its actual state when solving numerous fundamental and applied problems.

Relevance Today, there is a growing demand for the unmanned aerial vehicles usage to solve various types of problems. Moreover, unmanned aerial vehicles often designed and manufactured using standard imported components. The creation of electric unmanned aerial vehicles is promising, due to their environmental friendliness and reliability. Such aircraft are based on electric propulsion systems — electrotechnical complexes and systems consisting of an electric motor, an inverter electronic unit and a propeller. Aircraft type electric unmanned aerial vehicles are widespread due to their high range and flight time. Electric motors of aircraft type unmanned aerial vehicles are subject to increased requirements for noise and vibration levels, since the body of aircraft-type unmanned aerial vehicles can act as a resonator. As part of programs to ensure import independence of the Russian Federation, the development and research of electric motors for propulsion systems of electric unmanned aerial vehicles, including aircraft types, are relevant. Aims of research The main aim of the research is to determine the current technical and scientific level of developments in the field of electric motors for unmanned aerial vehicles. Identification of features and trends in research and development in the field of electric motors for unmanned aerial vehicles. Design, manufacture of experimental samples and research a brushless permanent magnet electric motor for unmanned aerial vehicles. Identifying a series of works aimed at developing a methodology for the design and research of electric motors for propulsion systems of unmanned aerial vehicles. Research methods During the design, methods of analytical calculation and computer finite element modeling were used. Experimental research methods were used to validate computer models and determine whether the created electric motor met the required parameters. To conduct experimental studies, a special stand was used with the ability to measure the thrust of the propulsion system. In the future, it is planned to use 3D scanning methods and restore the geometry of propellers for coupled models. Results As a result of the work carried out, an electric motor for aircraft-type unmanned aerial vehicles was developed and researched. Features that must be considered during design were identified. Several works have been identified that will be carried out as part of the design and research of electric motors for unmanned aerial vehicles, aimed at creating a new high-precision interdisciplinary design methodology. The work carried out is the basis for the development of new and scientific approaches to the creation of electric propulsion systems for unmanned aerial vehicles.

The article presents the experience of creating an innovative format of extracurricular training of applicants as a means of implementation of education for sustainable development – the experimental group “Cytoecologist”. The functioning of this format is based on the implementation of selected principles of STEM-education and open education of applicants. To implement these principles in the training of specialists, the group leader uses a number of formats of students’ activity that are not inherent in traditional education. Among them are dynamic temporary microgroups for experimental search; format “information activities”, Internet surfing, WIKI format, educational coworking or collaboration in space. The pedagogical experiment consisted of two parts. The first part is to find out the state of implementation of research skills by biology teachers in practice, which included determination of the level of their self-realization and interest in the organization of research activities of students. The second part is to find out the effectiveness of the presented experience of creation of a scientific student group “Cytoecologist”, within which the implementation of education for sustainable development by means of research activities of future biology teachers is carried out. A survey of graduates of the group shows that the basic principles of the group provide the formation of a stereotype of a specialist-researcher, and the vast majority of respondents (95%) use research skills in their professional activities, one of the directions of which is education for sustainable development. The experience of creating a research group of students presented in the article is the result of many years of scientific research of authors (teachers-practitioners of leading universities of Ukraine). This acquisition is original and is being published for the first time, and the obtained positive results give grounds to recommend it for implementation in the practice of training biology teachers in Western Europe.

Introduction. Oral communication is perhaps the most important skill while learning a foreign language. The conventional English teaching method that is applied at the different educational levels based on grammar and writing, does not allow the development of the necessary communication skills. The communicative teaching of language has been the subject of this research, in which its effectiveness has been treated using different resources and skills. Objective. This research aims to apply communicative language teaching activities to determine its effectiveness in the development of the speaking skill, in the second-year of Bachelor Education in a secondary institution in Riobamba, Ecuador. Methodology. A field, descriptive, prospective, longitudinal, quasi-experimental and quantitative research was carried out. The universe was made up of 94 students at that level. The sample equivalent to the universe was organized into two groups, one experimental and one control, with 47 students each. A diagnostic examination and a final test were applied for both groups, which during the time between both tests, followed different teaching-learning approaches. In the control group the traditional method was applied and in the experimental group, the communicative approach to language teaching. Results. The results showed that although both groups improved their performance in speaking, in the experimental group the increase in speaking ability was greater than in the control group. Conclusion. It was concluded that the application of communicative language teaching activities was effective in development of the speaking skill.

Experimental animal models are indispensable as they help to enhance the understanding of unknown diseases and contribute to new discoveries through their physiology, which facilitates the learning process and scientific dissemination. Consequently, the techniques applied to animal models require the development of guidelines that ensure respect for these animals and the reliability of the results obtained, in order to promote the advancement of scientific progress. With this in mind, the aim of the present study was to conduct a review on the use of reptiles as experimental models. The works were reviewed and selected based on their use of animals (reptiles) as experimental models and for having results relevant to the development of science and its various applications. In this context, analyzes that adhered to these principles were also considered, revealing that certain species of snakes, lizards, and turtles show promise for research in pharmaceuticals, the production of medicines and vaccines, as well as in seeking solutions to other problems related to animal health, for example, the study of baseline corticosterone (CORT) concentrations in rattlesnakes. Thus, we can conclude that, although these animals are not as commonly used in experimental research, reptiles hold an important position among vertebrates for investigating the progression of serious diseases, as well as for the development of vaccines and medications.

Introduction. The competitive advantage in the field of critical knowledge and technology exacerbates the problem of the effectiveness of intellectual activity and the means of its support in science, production and education. Such visual aids, formed by conceptual and graphic elements, such as concept maps, frames, structural logic diagrams, etc., contribute to the theoretical analysis and generalisation of the formed images and representations of learners. According to the degree of the development of these visual aids, the emphasis shifts from the function of visibility to the function of the organisation of activities. The term “visibility” (associated with the initial images of perception and representation) is substituted by the term “regulator” (focused on the organisation of further activities of the student). The hypothesis assumes the expediency of the development of conceptual and graphic means of visualisation in the form of visual didactic regulations, which are the subject of research.The present research aims: to discuss the problem of the creation of didactic regulations for educational activities; to study the development of conceptual-graphic means of visibility and factors for improving their functionality; to forecast the development of this type of means based on the visualisation of the logical-semantic modelling of knowledge; to clarify terminology and applied aspects; and to conduct experimental approbation in the conditions of distance learning.Methodology and research methods. The research methodology is based on the fundamental didactic principle of visualisation, which is necessary for the transition in the process of cognition from sensory perception to abstract thinking and contributes to the combination of abstract thinking with visualisation in teaching. The research methodology is also based on the method of logical-semantic modelling of knowledge and the following criteria for the study of conceptual-graphic means of visualisation: the application of the cognitive principles of knowledge representation; the use of universal instructional analysis activities to transform knowledge; the applicability of graphical representation of content. The methodology for the formation of didactic regulations included a visual presentation of the results of logical-semantic modelling of knowledge using universal educational actions and coordinate-matrix graphics. The method of experimental approbation of regulations in distance learning involved: the participation of students of four specialities and university teachers; a questionnaire survey of students; mastering, designing and using didactic regulations on the topic of experimental studies.Results and scientific novelty. The search on the databases of scientific documents of the Russian Academy of Education, the Electronic Scientific Library, Scopus, WOS and the Internet revealed the apparent lack of research and development of didactic regulations of a conceptual-graphic type. It was established that the main reason for the development of conceptual and graphic means of visualisation is the complexity of the tasks to be solved in science, production and education. It is demonstrated that the improvement of the functionality of conceptual and graphical tools is explained by the application of the principles of cognitive visual representation of knowledge and the method of logical-semantic modelling. The basic structures of the regulations were predicted and formed; the terminology of the research approach was clarified; the application of the tools for educational and project-based activities, interfaces of computer training programs is considered.Practical significance. The functionality of visual didactic regulators expands the potential of visibility and complements the tools of the teacher and the student. Moreover, they can be used in teaching technologies, research activities and design, when creating computer training programs.

This article discusses the problem of using statistical methods for processing experimental data in the study of quantitative and qualitative properties of phonemes based on literary texts. The article studies the duration of vowels in the Russian language and its analogues in English in statistical terms. The duration of speech sounds is measured in thousandths of second - milliseconds (ms). In English, stressed vowels are longer than unstressed. The authors of the article note that it is not the statistical apparatus itself that presents the greatest difficulties. It turns out that it is most difficult for a phonetic researcher to see a statistical problem in his linguistic hypothesis, choose the correct statistical procedure, and then give an adequate interpretation of statistical calculations in terms of a linguistic problem. The authors regret that despite the rapid development of applied, statistical linguistics, there are no methodological developments yet, as in other applied fields. So far, the only way for a researcher is equal mastery of both linguistic problems and the apparatus of mathematical statistics.In theoretical linguistics, linguistic research is usually divided into observation and experiment. The presented statistical methods apply mainly to observations. However, modern linguistics is becoming more and more experimental, especially in its field, which is called psycholinguistics.

Biomechanics is closely related to engineering, because it often uses traditional engineering sciences to analyze biological systems. Some simple applications of Newtonian mechanics and/or materials sciences can supply correct approximations to the mechanics of many biological systems. Applied mechanics, most notably mechanical engineering disciplines such as continuum mechanics, mechanism analysis, structural analysis, kinematics and dynamics play prominent roles in the study of biomechanics. Usually biological systems are much more complex than man-built systems. Numerical methods are hence applied in almost every biomechanical study. Research is done in an iterative process of hypothesis and verification, including several steps of modeling, computer simulation and experimental measurements. Prosthetics and orthotics are clinical disciplines that deal with artificial limbs (prostheses) for people with amputations and supportive devices (orthoses) for people with musculoskeletal weakness or neurological disorders and some disability person. The development of prosthetics and orthotics disciplines is depend on development of science and engineering. The understanding of this multidiscipline field is important the advancement in this field. In this session i will overview the current development in prosthetics and orthotics field, expl ain a brief survey on its method, and discuss perspective for future trend and development.

In this research, the effect of active listening training given to fourth grade students on their vocabulary was examined. Pre-test – post-test control group trial model, which is one of the semi-experimental trial models, was used. Besides, “Vocabulary Test” developed by the researcher was applied to experimental and control groups before the experimental implementations. The students in the experimental group were given a weekly two-hour-course of active listening training for eight weeks. The students in the control group were provided the materials forming the content of active listening training but they were made to study these materials with a weekly two-hour-course by traditional listening practice for eight weeks. At the end of the experiment, the test introduced as pre-test was also used as post-test in order to assess the differences between the groups. As the findings obtained from the research were analyzed, it was seen that active listening training positively contributed to vocabulary development levels of fourth grade students. Together with this, the other conclusion obtained from the research was that the students’ listening comprehension achievement contributed to learning new words.

Health saving-based educational technologies aim to provide a combination of children's needs, motivations, knowledge, optimal health level and normal physical development. In this study, the effect of the health-saving educational technologies program applied to secondary school students in increasing their physical fitness, self-efficacy in sports and mental endurance in reducing negative nutritional behaviors was examined. In the study, experimental procedures were carried out according to the 2x2 control group, pretest and posttest trial model. Experimental applications of the study lasted for 10 weeks, with 33 experimental and 33 control group students. During this period, the health-saving educational technologies program was applied in the experimental group; on the other hand, no application was made in the control group. Before and after the experimental procedure, pretests and posttests were applied to the experimental and control groups (Physical Fitness Test, Sports Self-Efficacy Scale, Negative Eating Behavior Scale and Mental Endurance Scale). According to the research findings, the students in the experimental group, who applied the health-saving educational technologies program, achieved higher levels of physical fitness, sports self-efficacy and mental endurance than their peers in the control group. It has also been found that the health-saving educational technologies program is effective in reducing negative eating behaviors.

AbstractKnowledge is a crucial factor in state-of-the-art product development. It is often provided by stakeholders from divers disciplinary and individual backgrounds and has to be integrated to create competitive products. Still, it is not fully understood, how knowledge is generated, transformed, transferred and integrated in complex product development processes. To investigate the dynamic interrelations between involved stakeholders, applied knowledge types and related artefacts, researchers at the TU Berlin conducted and evaluated a student experiment to study basic phenomena of development projects. In relation to research methods and instruments applied in this experiment, various improvement opportunities were identified. In this paper, the experimental setting and its results are critically analysed from a social science perspective in order to generate improved research design. Based on the results of this analysis, a first set of methods and instruments from social sciences are identified that can be applied in further experiments. The goal is to develop a methodological toolbox that can be used to approach research on knowledge dynamics in product development.
