The goal of the research is also to find a solution for textbook design that combines the benefits of an electronic book and an ordinary book by displaying images in three dimensions and content in an interactive manner to simplify and facilitate the information. The difficulty for primary school students to understand some curricula through ordinary textbooks is a research problem. In this study, we used a field study with a focus group discussion to achieve our goal, and we chose an informal ordinary book as the primary source, its title (into the crater of doom) and transforming its structure design into a pop-up book to present to primary school students and get their feedback on the method to design the pop-up book to use as an aid means of simplifying information for students, interacting with the book, and presenting the information in an interesting manner. The results of a discussion group with 33 primary school teachers divided into three groups revealed that 92% of them agreed that the design of the ordinary textbook should be updated. By presenting the researcher's pop-up book, all of them prefer to use the pop-up book as an aid in improving students' cognitive and intellectual skills. Furthermore, the results of the discussion groups with the students, a total of 35 students divided into three groups, revealed that all of them preferred to use the pop-up book in all textbooks, particularly science and social studies for 4th grade primary students. As well as making recommendations to the Ministry of Education on their performance regarding the positive impact on students of using pop-up books designed by the researcher as an aid means to students in schools and homes.","PeriodicalId":107864,"journal":{"name":"Proceedings - The Eleventh International Symposium GRID 2022","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115601485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lasheva","doi":"10.24867/grid-2022-p5","DOIUrl":"https://doi.org/10.24867/grid-2022-p5","url":null,"abstract":"Paper aging depends on the type and chemical composition of the fiber raw materials, the chemical additives used, such as dyes, fillers, sizing additives, pH and others as storage conditions of the paper (relative humidity and temperature) and the degree of exposure of temperature, light and some microbiological factors. The durability of paper is its ability to retain certain physic-mechanical, optical and chemical properties unchanged over time. In this context and in line with the increased consumption of coated or treated printing and packaging papers, the aging resistance of treated or coated paper is of a great scientific, research and applied interest. This research work inherently involves preparation and properties evaluation of thermal stability of packaging papers treated of silver water. In order to examine this process for woodfree packaging paper, accelerated thermal aging for 72h at temperature of 105°C and dynamic thermogravimetric analysis (TGA) was carried out of a pulp sample and four paper samples (three of them treated with silver water – 1, 2 and 3 ml) together with the structural-dimensional and strength properties of the laboratory obtained paper samples. The degree of colour changes in the CIELab colour space have been studied, bearing in mind that the changes in colour characteristics define the stability over time and even more – the influence of the silver water treatment. As a result of the studies carried out it was found out that paper do not change significantly during 72h of accelerated thermal ageing, but it is not recommended to be used more than 2 ml of silver water, as silver ions probably catalyze the aging process and the paper darkens and turns yellow in a greater degree. The change of the weight of the paper samples as a function of temperature was monitored by TGA. When comparing the weight losses, it was found out that for the paper sample treated with 2 ml of silver water the temperature of complete burning of the sample increased by 2.28°C. In addition, the surface of the treated paper samples is more even compared to the untreated due to the callandering effect of the manufacturing process.","PeriodicalId":107864,"journal":{"name":"Proceedings - The Eleventh International Symposium GRID 2022","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117138830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metal nanoparticles (NPs) have become a leading area of interest and research in barrier packaging materials that ensure food safety. Traits such as small size, high surface-to-volume ratio and multi-functionality make them ideal materials for producing self-sterilizing packaging. Numerous metal NPs have proven to fight against a wide range of pathogenic microbes through various methods. Further, metal NPs exhibit more biocompatibility than metal ions. This study investigates the role and the mechanism of action of the various NPs in selfsterilizing packaging. AgNPs, TiO2NPs, MgONPs, ZnONPs, AuNPs, FeONPs, Cu-based NPs and SnO2NPs have been explored for their biocidal action in self-sterilizing surfaces and food packaging applications in this work. The size, shape, surface structure, surface reactivity and other environmental factors (like pH) influence the biocidal properties of these metal NPs. From the literature survey, it was inferred that it was necessary for the metal NPs to be smaller than 50 nm in size to exhibit effective biocidal action against pathogenic microbes. The mechanisms followed by the metal NPs against bacteria and fungi include disturbing the cell wall, the metabolic process by inducing reactive oxygen species (ROS) and/or the DNA synthesis mechanism. It was inferred that AgNPs, MgNPs and ZnONPs are some of the NPs that have a significant share in self-sterilizing surfaces. Being expensive, the works of literature on AuNPs and their application in this subject are very few. This paper aims to study the biocidal behaviour and rank the effectiveness of these metal NPs to act as ideal materials for self-sterilising packaging.","PeriodicalId":107864,"journal":{"name":"Proceedings - The Eleventh International Symposium GRID 2022","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125332879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the aim of our research, as systematic review, was to identify, summarize, and evaluate existing sustainable packaging solutions in the apparel and footwear industry. The study followed the principles of a systematic review,research methodology, using a website search; Phyton programming language libraries were used to develop a web scraper. A sample included apparel and footwear brands that operate internationally around the World. The qualitative analysis method of thematic content clustering was then used to identify, summarize, and evaluate the results. The results have shown that less than half of the brands announced their long-term commitment to switching to sustainable packaging. Less, 84 brand have certificates for all or certain types of their packaging. There are 60 brands that offer reusable packaging services through collaboration with packaging providers. Only 52 of 400 brands have invested in eco-friendly packaging solutions and 32 joined to Responsible Packaging Movement and Ellen McArthur foundation. We found out that most of the brands with the sustainable statements and packaging solutions are from Europe (54.50 %). Others are from North America (28.25 %), Australia (10.10 %) and Asia (3 %). As expected, the clothing categories with the most sustainable packaging solutions are clothing for women and men, less footwear and accessories. The results of our study suggest that sustainable packaging is highly dependent on the social and environmental impacts, as well as the business and supply chain circumstances associated with each product packaging system. Apparel and footwear brands are generally committed to finding better packaging solutions for their products, although innovation in this area is still reluctantly shared.","PeriodicalId":107864,"journal":{"name":"Proceedings - The Eleventh International Symposium GRID 2022","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125462314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of jackfruit seed starch on strength properties such as tensile strength and elongation, as well as waterrelated characteristics such as water contact angle, water vapour permeability, and moisture content, were evaluated and compared with the results of the control blend films. FT-IR, TGA, SEM, XRD were performed to identify the functional group and its potential interactions, thermal stability, surface morphology and crystallinity of prepared films. The results suggests that addition of jackfruit seed starch from 0 to 1.5 g enhanced the tensile strength from 26.62 MPa to 33.26 MPa, but thereafter the tensile strength drops to 32.58 MPa and the elongation decreases. When compared to the carboxymethyl cellulose carrageenan control film, some physical parameters of the film, such as water vapour permeability and moisture content, decreased while thickness and contact angle increased significantly. The results of scanning electron microscopy exhibited rough and heterogeneous morphology for films with more starch content, while the control films exhibited smooth and homogenous structure. The presence of starch increased the crystallinity of all films, which attributed to improved thermal and mechanical stability of the prepared films.","PeriodicalId":107864,"journal":{"name":"Proceedings - The Eleventh International Symposium GRID 2022","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a key factor can be considered the 3D printing technology, which is already widely accessible, offering customisable possibilities without expensive tooling based on individual specifications. Furthermore, the opportunity for recycling and degradation of different plastic materials and the creation of a filament for 3D printers has large impact on the product life cycle. The aim of this study is to highlight the management of recyclable plastic by creating new customized products.
