LIVING LEARNING FROM NEAR DEATH EXPERIENCE

The main aim of the article is to clarify what changes a near death experience (NDE) brings in the living learning process of an adult and in his attitude towards it. The existential experience, and the perceptions about life and death are considered as important self-realization and development factors in the learning process. Although currently there is no single scientific position with respect to NDE, the inner experience of the humans who have survived clinical death and as a result of that had personality change cannot be denied. In the context of pedagogy according to the phenomenological scientific methodological tradition NDE gives its contribution both in the procedure of cognition and in the field of the cognizable facts. In order to identify the relationship between NDE and living learning, in-depth interviews were conducted with 5 people who have experienced clinical death. The results of the interviews allow to identify several common change categories of the attitude and understanding related to living learning. These include the examination of one’s own way of existence, understanding of the unity of all existing, the appearance of a deeper sense of responsibility, new interests and the related intuitive knowledge, the change of attitude towards knowledge, religion and self-knowledge

USE OF DIFFERENT TECHNIQUES OF VISUALIZATIONS IN THE TRAINING OF ENGINEERING SPECIALISTS: NEEDS VERSUS APPROACHES

The quality of engineering education is closely related to the development of spatial skills of students and the ability to create and read the drawings. Visualization improves the efficiency of the information; as for visualization of geometric tasks of graphical subjects, it helps students faster comprehend complex spatial problems and solve the given exercises.The given article describes the study of the methodology of teaching graphical subjects from the point of view of methods of representations of education materials, the degree of inspiration and engagement of students in learning activities. The research was conducted in Latvia, Lithuania, Spain, Germany and Poland within the project "Contemporary Approach to the Development of Spatial Comprehension through Augmented Reality Content" (SPACAR).

CONTEMPORARY NEEDS OF MEDIA LEARNING MATERIALS FOR FUTURE Z-ENGINEERS

Modern students are digital natives: from an early age, they are used the Internet, social networks and mobile systems. Due to the specific brain structure of Generation Z students, the use of traditional teaching tools makes the learning process not effective. Also, an insufficient number of lecture hours in curricula requires from students more independent work. This article presents the experience of creating interactive teaching materials designed to study and master the skills of graphical engineering subjects. Educators of technical universities from five countries took part in the development of the material. These interactive teaching tools are created with the aim of improving the quality of engineering education, the rapid and effective presentation of educational material, which will contribute to the understanding of difficult topics.

TRIGGERING THE STUDENTS' POSITIVE ATTITUDE FOR THE STUDIES OF ENGINEERING GRAPHICS COURSES THROUGH THE AUGMENTED REALITY CONTENT

Contemporary researches show that triggering interest can enhance students’ thinking skills, creativity, joy of learning and improved performance. The digital technologies can be beneficial for students’ learning engagement and motivation. The digital context helps students to keep positivity in education process that allows to activate attention, memory, and makes learning skills better. Augmented Reality is one of technologies that lets you interact with the real world and virtual objects at the same time. Augmented Reality application enables faster comprehension of complex spatial problems and relationships, which makes it useful during the learning process of engineering graphic courses. In this paper the application of AR technologies in RTU engineering courses is described. The results of this approach will be useful for vocational school teachers, college and university teachers in the successful integration of AR technologies in the teaching process

The Visualizations Methods of Geometrical Forms in teaching of Civil Engineering Students

Development of spatial representation (the ability to imagine three-dimensional objects using flat pictures or drawings), skills of the intuitive decision of spatial problems and more meaningful use of CAD software are essential for qualified education of students. Visualization of geometric problems helps students to understand and to solve the given geometric tasks. The paper describes types of visualization of geometrical objects from graphic exercises of compulsory subject “Civil EngineeringGraphics”. This course is specified for Civil engineering undergraduate 2nd year students of Riga Technical university.Performance of a breadboard model, creation of the given model using ArchiCAD and using augmented reality (AR) software are included in the course "Civil Engineering Graphics” assignments. The examples of the tasks of 3D modeling in learning process are presented in this article. AR application allows faster understanding of complicated spatial problems and relationships and was used to entertain the students during the studies. Before mentioned approach was enabled to develop spatial skills of students, facilitate the students to obtain more practical experience in solving graphic exercises and was supposed enhance the quality of graphic education.

Health disorders of the employees exposed to organic solvents at work

Funding Information: The surveys were carried out in collaboration with TNS Latvia Ltd. in the frame of the Project “Studies of the Ministry of Welfare” of the National Programme “Labour Market Studies” financed by the European Structural Fund.The aim of the study was to investigate the impact of exposure of organic solvents at work on related health disorders in Latvia. Two surveys were carried out with a total number of 2520 respondents. Retrospective analysis of incidence of occupational diseases caused by organic solvents was performed. 21.4% of employees indicated absorption of chemical substances through skin. The incidence of occupational diseases caused by organic solvents has a stable trend to decrease from year 2003. 58.8% of employees believe that their long-term health disorders are related to their work environment or work conditions. While organic solvents remain an essential working risk problem in Latvia, the data on exposed persons and their health disorders caused by organic solvents are not sufficient enough. Biological monitoring could facilitate early diagnostics of non-specific health disorders caused by organic solvents.publishersversionPeer reviewe

Marine yeast (Candida sake) cultured on herring brine side streams is a promising feed ingredient and omega-3 source for rainbow trout (Oncorhynchus mykiss)

A major challenge for the aquaculture industry is the supply of sustainable feeds. A promising model to achieve this is to utilize circular flows where feed ingredients, such as single cell protein, are cultivated using side streams of the food industry. The aim of this study was to evaluate the marine yeast Candida sake, produced on herring brine side streams, as a source of protein and immune stimulant in feed for salmonid fish. The dry C. sake product contained 54% protein (3.3% lysine and 0.8% methionine) and 13% lipids (1.1% eicosapentaenoic, EPA, and 1% docosahexaenoic acid, DHA). Four experimental diets were designed and tested in a 9-week feeding trial using juvenile rainbow trout (Oncorhynchus mykiss). A control diet containing both fish and plant-based ingredients constituted the base feed to which 20% (to evaluate effects on digestibility, growth and intestinal physiology), 20% heat-treated (to evaluate effects of downstream processing) and 3% (to evaluate immune stimulatory properties, replacing 3% soy protein concentrate) C. sake was added. The apparent digestibility coefficient of C. sake for protein, fat and gross energy was above 80%, and for amino acids above 90% regardless of treatment, suggesting a high bioavailability of C. sake. All three yeast containing diets performed equally to the control regarding specific growth rate, feed conversion ratio and functional intestinal health. These results suggest that C. sake is a promising alternative protein source for circular feeds in the salmonid industry. The presence of EPA and DHA represents an added value. The heat treatment increased the apparent digestibility coefficient of dry matter by 8% but decreased amino acid digestibility by on average 3%, indicating that heat treatment may not be the optimal downstream processing technique. Furthermore, the inclusion of 3% C. sake increased the intestinal lamina propria width and TGF-β transcription, indicating an immune stimulating effect. Future research is needed to understand these immune modulatory effects of C. sake supplementation

Comparison of nice classification for optical diagnosis of colorectal polyps and morphology of removed lesions depending on localisation in colon

Publisher Copyright: © 2022 Ilona Vilkoite et al., published by Sciendo.The narrow-band imaging (NBI) International Colorectal Endoscopic (NICE) classification is based on narrow-band pictures of colon polyps viewed through a narrow-band spectrum. The categorisation utilises staining, surface structure, and vascular patterns to differentiate between hyperplastic and adenomatous colon polyps. It is known that accuracy of the NICE classification for colorectal polyps varies depending on the localisation in the colon.The aim of this study was to compare the diagnostic accuracy of the NICE classification and the gold standard - morphological analysis for the determination of the type of colorectal lesions depending on localisation in colon. A prospective study was performed in an outpatient clinic. 1214 colonoscopies were performed by two expert endoscopists and 475 polyps were found in 291 patients. The overall diagnostic accuracy of the NICE classification was 80.3%. Optical verification was better in ascending colon - 93.9%, followed by sigmoid colon - 82.1%. Inferior results were found for the descending colon - 64.0%. The results of this study showed that the NICE classification could be a helpful instrument in daily practice for the ascending and sigmoid colon. For better results, proper training should be considered. The NICE system could have a role in the replacement of morphological analysis if appropriate results of verification could be achieved.publishersversionPeer reviewe
