Manufacturing A Personalised Composite Material Driver’s Seat

The paper presents the process of 3D-printing and laminating a composite material driver’s seat for Silesian Greenpower’s electric vehicle. Silesian Greenpower is a student’s interfaculty project, of which aim is to design, build and race a small electric race car. Aerodynamics and lightweight construction play a major role, so each element applied in the car is optimized and customized to fit in the vehicle. For this purpose, 3D-printing technology is often used by the team. A seat model made on the basis of the driver's anthropometric model was presented in the paper. Subsequently, after the appropriate adaptation of the obtained surfaces to interconnect them with each other, the FDM technology was applied using PET-G material. To increase the strength of the connections of the printed elements and to strengthen the design and stability of the chair, the element was laminated using carbon fibre and epoxy resin. The lamination process is presented and discussed in the article.

The Holistic Approach of Homoeopathy

The very foundation of homoeopathic practice considers man not only as an individual, but as a complete unit in himself, of which all his parts comprise a well-balanced whole. Homoeopathy, therefore, does not consider any one part as being ill, but considers the manifestation of illness in one part in its relation to the whole man. Homoeopathy has evolved as an logical, experimental science according to the method of inductive reasoning where in the exact observation, correct interpretation, rational explanation and scientific construction play a leading role. Homoeopathy accepts surgical measures when directed towards the removal of mechanical impediments to cure or of the morbid end-products of disease when they interfere with recovery. On the contrary Homoeopathy has played a pivotal role in avoiding surgeries and curing many such diseases where surgery was recommended.

Constructed Pasts

LEGO bricks are one of the world’s most popular toys, part of a class of postwar playthings that addressed middle-class ideals of childhood creativity and educative play. As the company adapted to a globalized consumer culture in the second half of the twentieth century, however, it also relied on longstanding tropes of gender, history, and cultural others that put pressure on its claims as a provider of wholesome, “universal” play. This article unpacks how LEGO’s product designs, marketing, and theme park operations have commodified historical inequities, giving tangible form to stereotypes of a racially unmarked European past, colonial encounters with the “uncivilized,” and the gendering of domestic space and construction play.

The main directions of education development in the conditions of digitalization

The article discusses the urgent problem of the education system - the preschool education development in the context of digitalization. The solution of this problem is facilitated by the creation of an information and educational environment, as well as the use of information and communication tools in communication, construction, play and other types of productive creative child activity. The authors of the article presented in detail four directions of the preschool education development in the context of digitalization: the creation of an information and educational environment (IEE) that meets the requirements of the harmonious holistic development of preschool children; ICT software assuring electromagnetic safety; introduction of new information technologies; formation of information competence in subjects of educational relations; and also gave an example of the use of these directions in the preschool educational institution (PEI) and the developed methodological sequence in the implementation of program content. The use of telecommunications, Intranet and Internet networks, telephone communications, etc. for the exchange of information brings variety to the joint activities of children and teachers. The authors of the article note that for the preschool education development in the context of digitalization, it is necessary to create in PEI a regulatory and legal framework, psychological and pedagogical conditions, a material and technical base, electronic educational resources, a criterion-diagnostic base, as well as to organize work with children, parents and teachers.

SHEET BUILDING GLASS WITH PROTECTIVE AND DECORATIVE COATINGS

sheet glass with decorative coatings in industrial and civil construction play an important role in improving the aesthetic properties of buildings for various purposes. An innovative technology for obtaining decorative coatings on sheet glasses using low-temperature plasma is proposed. For plasma spraying crushed in a ball mill container glass of various colors was used. The optimal parameters of the plasma spraying of glass powders on the front surface of the glass sheets were established. To increase the adhesion strength of the coating to the substrate before plasma spraying, the front surface was heat treated with outgoing plasma-forming gases. It was found that with increasing temperature of the outgoing plasma-forming gases and the time of their impact on the front surface of the sheet glass, the adhesion strength of the coating with the base increases to 6.7 MPa. The effect of the coating thickness on the strength of its adhesion to the substrate is studied. Increasing the coating thickness from 150 to 1000 µm reduces the adhesion strength from 7.5 to 3.2 MPa. Under the influence of high temperatures of arc plasma is not only an increase in the glass refractory oxides of silicon and aluminum, but also an increase in their hardness up to 15%.

Early mathematical education in narrative contexts and the local environment

The article describes the implementation of the project that took the form of a teaching experiment. The “Myśleć jak architect” [en. “Think like an Architect”] project was aimed at developing children's spatial, mathematical and creative skills, integrating the social environment: academic, educational, family and cultural, and promoting science. Its essence was to design and conduct a mathematical and creative didactic cycle in the university space and in the local cultural space. The essence of educational meetings were: play, tasks, games and mathematical problems undertaken and solved by children in active and creative action, also using innovative teaching materials. The workshop didactic program was designed as a cycle of 12 hours of didactic classes, in which there was a deliberate use of rhymes, poems, fairy tales and mathematical narratives. The project lasted from November 2018 to May 2019. The beneficiaries of the project were the oldest pre-schoolers and younger students from grades I-III, in 9 groups, each consisting of 12 people. The study confirmed the effectiveness and attractiveness of integrating literature with mathematics and learning mathematics in various areas. The study has shown that the strategies for teacher management of construction play using narration are an important and effective ways of supporting the development of a child's mathematical thinking.

Selecting a proper construction system in small and medium mass housing projects, considering success criteria and construction volume and height

Purpose As the population grows, one of the major global crises is the management of human settlement. A proper solution to deal with this issue is mass housing. Given the variable needs in these projects, two constraints of height and volume of construction play an essential role in fulfilling success criteria. Hence, this paper aims to choose the most appropriate building method to satisfy time, cost, quality and safety factors considering the volume and height of construction. Design/methodology/approach In this research, the proper construction methods in mass housing projects in two volumes of up to 1000 (small) and 1000-3000 (medium) residential units in three ranges of the height of 5, 5-10, and higher than ten floors were determined with a focus on the success criteria based on real experiences through questionnaires and interviews. Findings The results show that steel bolt and nut and tunnel framework systems in higher than five-floor building projects act better than other methods, while in up to five-floor building projects, LSF saves time and cost and steel bolt and nut provides higher quality and safety. Originality/value Given the extent of work, the results of this research can be considered as a benchmark in the mass housing industry.
