Features of design, construction and technology of manufacturing galvanoplastic jewellery

The features of design, construction and manufacturing technology of electroplated jewellery are considered. The classification of jewellery made by the method of electroforming, based on their areas of application, is presented. The technological features of the formation of the surface of products with a “posi-tive” and “negative” build-up of the deposited metal, ways of reducing the roughness of the deposited coat-ings with an increase in their thickness are considered. Methods of creating suspension and fastening ele-ments of the product structure are described. The main modern trends in the development of technology and design of products made by the method of electroforming are considered: the use of 3D technologies in the development and creation of models, the use of conductive polymer compositions for the manufacture of models, computerization of the technological process of forming metal deposits of precious alloys of a cer-tain carat and colour. Modern technological methods allow raising the level of electroplated jewellery de-sign to a new level.

HISTORICAL TRAILS OF SHIP BROACHING-TO

The article intends to bring back to light old perceptions about the “broaching-to” behaviour of ships. The signature of broaching-to is the sudden loss of controllability. The phenomenon sometimes ends with vessel capsize. The findings of an investigation into old bibliographical sources are reported, spanning more than 300 years of use of the term. Several citations have been identified in texts of nautical or related content, including voyagers’ records, nautical journals, training manuals, old encyclopaedias and even literary sources and leisure magazines. At a time when broaching-to is considered in the currently formulated new ship stability criteria at IMO, this paper provides a historical perspective on a problem that has maintained relevance despite the changes in ship technology and design.

STEM ATTITUDES OF STUDENTS AS PREDICTOR OF SECONDARY SCHOOL TECHNOLOGY AND DESIGN COURSE ACHIEVEMENT

Achievement in a course mostly depends on the students' characteristics and how teachers make their courses effective for their students' learning. Although different characteristics of teachers and students can affect learning outcomes, new approaches like STEM may cause new characteristics which affect students’ achievement as STEM attitudes. This study examines the correlation between secondary school students' STEM attitudes and their achievement in the Technology and Design Course (T & DC). A correlational survey model was applied in the study. A total of 400 students studying in the seventh and eighth grades constitute the sample of the study. A personal data form and STEM attitude test were utilized to collect data. Pearson Correlation Analysis and Regression Analysis techniques were used in the data analysis process. As a result of the analysis, it was found a positive and significant correlation between students' Technology and Design Course achievement and STEM attitudes. Students' attitudes to STEM predict their achievement in the Technology and Design Course by 5.1%. Students developing positive STEM attitudes can further enhance achievement in the (T&DC), which enables students to acquire the necessary design skills to produce technology in the future. Keywords: academic achievement, correlational survey, secondary school, STEM attitude, technology, and design course

A- Level Textile Technology and Design Curriculum Compatibility with Industry Requirements in Harare, Zimbabwe

Through descriptive design, this study sought to establish the compatibility of the A-level Textile Technology and Design (TTD) curriculum with the industry requirements in Harare, Zimbabwe. The study employed both quantitative and qualitative techniques through a questionnaire and interview schedule. The population comprised of 120 A-level learners and five teachers from five schools as well as eight factory managers. Forty learners who had studied the subject for at least one year and teachers based on their experience in teaching were purposely selected to constitute the sample. Three factory managers from clothing industries in Harare City were conveniently selected based on their willingness to participate in the study. Data was treated through descriptive statistics and thematically. The study established that learners did not acquire adequate essential concepts in designing, pattern making, computer aided designing, use of industrial sewing equipment and business enterprise which are critical for business or employment in the clothing industry. Some study areas were found to be compatible with the requirements of the clothing industry and entrepreneurship, but the content was not well taught. Teachers were not proficient with new skills and knowledge in the updated syllabus. The majority of the learners was either neutral, disagreed or strongly disagreed to have acquired the intermediate skills related to the updated Textile Technology and Design Curriculum. Therefore, a more skills based curriculum is recommended. In-service training of TTD teachers in business and entrepreneurship skills is also recommended.

Ukrainian Folk Ornaments in Modern Knitting

National arts and crafts are not only the skills of an individual nation but an ethnic phenomenon that has unique features and serves as a source of information on national history and culture. Decorative and applied art in Ukraine combines the traditions and techniques of manufacturing and decoration, which have been developed and passed down from generation to generation. It has a clear national identity and numerous regional differ¬ences in ornamental motifs, compositions and favourite colours. Therefore, the Ukrainian folk art has a significant potential and is a source of ideas in creating modern clothing as well as interior items. Embroidery as a way of creating ornamental motifs on a textile material using various techniques is a common process for decorating clothes and interiors for the Ukrainians. Today, ornamental compositions of embroidered folk textiles could be transmitted into modern clothes using various technologies. However, the use of a knitting machine allows creating a pattern during the item production. The ornament transformation into a pattern for knitting can be carried out with graphic software by creating a grid with a cell size similar to the loop size of a knitted structure for corresponding interlooping. A number of clothing and interior items with ethnic motifs was created using the capabilities of flat knitting machines within the masters programme “Knitting Technology and Design” at the Textile Technology and Design Department of the Kyiv National University of Technologies and Design.
