Apparel from the local brands are becoming more and more popular in Bangladesh as well as around the world. In this study, qualitative and quantitative data both are used to evaluate how these students are currently buying local clothing products. The target audience for this study are textile engineering students of Bangladesh. This is a niche segment because these students possess knowledge about the manufacturing process that a regular buyer does not. It is safe to say, this segment of buyers are subjected to the brands and their products to additional scrutiny possibly indicating gaps in the market. Which can provide the clear concept about the current situation of local brands in the apparel market. Here, primary data from the questionnaire responses are analyzed using Microsoft Excel to draw conclusions about the project results from different statistical analysis. The data analysis results suggested that about 70% of students often buy apparel from a range of local brands, compared to only 9% of students who frequently shop at brand stores. In addition, budgets for festival-specific clothing make up around 6.88% of those of textile engineering students. Therefore, this study revealed the real scenario of local brands and their scope in the apparel market of Bangladesh.

A novel concept in the realm of conventional electricity grids, known as the “smart grid,” has emerged to explore the most effective methods for integrating green and renewable energy sources. By leveraging existing technologies for its communication network, the Smart Grid also inherits their associated drawbacks. Exploiting these vulnerabilities can lead to severe consequences such as privacy breaches, cascading failures, or even system-wide blackouts. Securing the Smart Grid is now paramount to ensuring its optimal performance. This document aims to provide a comprehensive analysis of the Smart Grid. We begin by examining its inherent weaknesses, followed by a classification of common attacks and their potential impacts. Subse-quently, we delve into strategies for mitigating and detecting these attacks, utilizing appropriate algorithms. Lastly, we address current research challenges and propose future initiatives aimed at enhancing cybersecurity measures to safeguard smart grids from cyberattacks. Moreover, this review emphasizes the intricate relationship between technological vulnerabilities and cybersecurity challenges within the Smart Grid framework. It offers a nuanced perspective that highlights specific areas requiring heightened attention to establish an effective and robust defense against potential threats.
