Effect of an E-Educational Poster on Improving the Knowledge, Attitude, and Practice on the Proper Use of Face Masks among School Students

Introduction: Two spread methods of Covid-19, namely airborne and respiratory droplets, can be prevented by proper use of face masks. However, it has been reported an inadequate knowledge attitude and practice of proper use of face masks among school students. Therefore, the knowledge, attitude, and practice of school students should be improved. Different approaches are used to improve knowledge, attitude, and practice. However, e-posters are rare, and the effect of e-posters on improving the knowledge, attitude, and practice of school students on the proper use of face masks has not been studied. Objectives: The objective of this study was to determine the effect of an e-educational poster on knowledge, attitude, and practice of the proper use of face masks among school students. Method: This study was conducted as a pre-test and post-test design. The sample was 364 grade 11 students of the Gampaha educational division, Sri Lanka. Data were collected using self-administered questionnaires distributed pre and post to the interventional e-education poster. Data analyses were conducted by using SPSS Software. Results: Results show no significant demographic difference (p = 0.446) between the pre and post-test groups. A significant increase was observed between the pre and post-test mean scores of knowledge (p ≤ 0.05), attitude (p ≤ 0.05), and practice (p ≤ 0.05) on the proper use of face masks. In pre-group knowledge (p = 0.155), attitude (p = 0.258) and practice (p = 0.211) shows no significant difference due to gender. Also post group knowledge (p = 0.079), attitude (p = 0.835) and practice (p = 0.435) shows no significant difference due to gender. Conclusions: The results suggest that e-educational posters may be useful to improve the knowledge, attitude, and practice on the proper use of face masks among school students. The improvement of knowledge, attitude, and practice on the proper use of face masks by e-educational posters among school students occurs irrespective of gender.

Semiotic Resourcefulness in Crisis Risk Communication: The Case of COVID-19 Posters

The unprecedented outbreak of COVID-19 presents a public health crisis on a global scale.Various measures have been taken to communicate crisis risks to the general public.These measures are meant to keep the public well informed,stay alert,and take precautionary measures to help curb the spread of the virus.The current study is part of an ongoing project aimed at exploring patterns of communication in the COVID-19 crisis discourse.Based on a collection of posters designed for public use during the outbreak,this paper analyses the richness of semiotic resources that combine to construct and convey the intended message of the posters.Drawing from scholarly insights into understanding the situatedness of meaning-making,the paper revisits some of the classical concerns about the relationship between text and image in semiotic artefacts and reveals the meaningmaking patterns in the semiotic designs of risk communication posters.The patterns are found to rest upon a host of textual and graphic features that contribute to the essential semiotic encoding of entity,condition,action,and sentiment.The findings are summarized by conceptualizing the assemblages of resources in the poster as a semiotic ensemble where the coordination and collaboration among semiotic resources can work to reduce potential ambiguities and amplify the communicative effect.

基于图像叙事表达的公益主题海报设计研究

目的探究图像叙事理论在公益海报创作过程中的应用方法和创新设计策略,将COVID-19主题的图像叙事特征与受众心理需求相契合,使海报传播的文化价值得到有效提升。方法通过分析图像叙事理论下公益海报设计的基本特征,结合COVID-19叙事主题,采用5W1H模式分析叙事元素并构建叙事空间,利用视觉思维论述受众审美特征与心理诉求,借用意象论和图形创意法,对用来修辞海报主旨的图形符号进行视觉语言转换。结果基于图像叙事原理结合受众情感诉求进行设计实践,从受众认知、感知、反思三个层面,构建海报设计流程的垂直化思维,使公益海报的多维语境与文化价值得以深度传播。结论图像叙事理论介入公益主题海报创作,可以让海报画面语义表述更加丰富,进一步加强了与受众的情感沟通,使公益海报的视觉表现、引导功能和价值观念传播得到有效提升。同时,能够解决单一的形式美法则、无法满足受众情感需求和复杂的设计流程等问题,为公益海报再设计提供了参考和思路。
