Mindfulness works by training the brain to focus on the present moment, rather than dwelling on the past or worrying about the future. This involves paying attention to one’s thoughts, emotions, and physical sensations without judgment, and acknowledging them without becoming overwhelmed by them. By practicing mindfulness regularly, students in Bangladesh can develop a greater sense of self-awareness and learn to manage their thoughts and emotions in a more constructive way.

Studies have shown that mindfulness can actually change the brain’s neural pathways, resulting in increased activity in regions associated with positive emotions and decreased activity in regions associated with negative emotions. This can lead to a greater sense of well-being and reduced stress levels. Additionally, mindfulness has been found to have a positive impact on the immune system, resulting in improved physical health.

In short, mindfulness works by rewiring the brain to focus on the present moment and manage thoughts and emotions in a more positive and constructive way. With regular practice, students in Bangladesh can reap the many benefits of mindfulness and improve their overall well-being.

  1. Importance of Mindfulness for Students in Bangladesh

There are several benefits of mindfulness for students in Bangladesh, including:

  • Improved academic performance: When students practice mindfulness, they learn to tune out distractions and stay focused on their studies, which can lead to improved academic performance.

  • Increased self-awareness: By practicing mindfulness, students can become more aware of their thoughts and emotions, and develop a greater sense of self-awareness.
  • Improved mental health: Mindfulness can also improve mental health by reducing symptoms of depression and anxiety.

According to a report published by the Dhaka Tribune, the demand for mindfulness and meditation programs has increased by 50% in the last five years in Bangladesh. The report highlights that people from various backgrounds, including students, professionals, and homemakers, are seeking mindfulness practices to improve their mental health and well-being. The report suggests that the increasing demand for mindfulness programs in Bangladesh indicates a growing awareness of the importance of mental health and well-being.

  1. How to Practice Mindfulness: There are several ways that students in Bangladesh can practice mindfulness, including:
  • Meditation: Taking a few minutes each day to meditate can help students stay centered and focused.
  • Breathing exercises: Deep breathing exercises can help students calm their minds and reduce stress.
  • Mindful eating: Eating mindfully, by paying attention to the taste, texture, and aroma of food, can help students develop a greater appreciation for the present moment.
  • Mindful walking: Taking a walk and being fully present at the moment can help students reduce stress and improve their mental health.

In conclusion, mindfulness is a valuable tool for students in Bangladesh that can help them stay focused, reduce stress, and ultimately achieve greater academic success. As a teacher, I encourage my students to practice mindfulness regularly, and I have seen firsthand the positive impact it can have on their lives. By taking just a few minutes each day to practice mindfulness, students in Bangladesh can improve their mental health and overall well-being.

Relation between detail area plan & working drawing

A detailed area plan and a working drawing are two different types of drawings used in the field of architecture and engineering section. However, there is a relationship between them as they provide important information about a construction project.

Detail area plan:

A detailed area plan is a type of architectural or engineering drawing that provides an overview of a specific area, such as a building floor, site or landscape. It is a detailed graphical representation that includes all the important information about the area, including the location of walls, doors, windows, and other structural elements.

A detailed area plan can also include information about the materials and finishes to be used in the area, as well as the dimensions and measurements of each element. It is typically used by architects, designers, and engineers to communicate their design ideas to clients, stakeholders, and contractors.

                                                                         Fig: Detail area plan

Working Drawing Plan:

Architectural working drawings are technical drawings created by architects and architectural drafters that provide detailed and precise information about the design of a building. These drawings are used to communicate design specifications and construction details to contractors, builders, and other professionals involved in the construction process.

Architectural working drawings typically include floor plans, elevations, sections, and details. Floor plans show the layout of the building and the location of walls, doors, windows, and other elements. Elevations show the vertical appearance of the building and the location of the doors, windows, and other openings. Sections show a cut-through view of the building, which reveals the interior structure and details. Details provide specific information about the construction and materials used for various building elements, such as the roof, walls, and foundation.

Architectural working drawings serve as a critical communication tool between the design team and the construction team, ensuring that the building is constructed according to the designer’s specifications and requirements. They are also important for obtaining necessary permits and approvals from local authorities and for estimating project costs.

Relation between detail area plan & working drawing plan:

The detail area plan is a type of drawing that provides detailed information about a specific area or component of a building, while working drawings are a set of technical illustrations that provide precise and accurate information about the design and construction of a building. The detail area plan is typically included as part of the set of working drawings, and it provides a more detailed view of a particular area or feature than is shown in other types of drawings. Both detail area plans and working drawings are important tools for architects and builders, as they provide essential information about the design and construction of a building. 

In summary, the detail area plan is a type of working drawing that provides detailed information about a specific area or feature of the building. It is a component of the set of working drawings that is used to provide precise and accurate information about the design and construction of the building.

Find out what qualities and talents the company is looking for, and make sure to highlight them in your cover letter and CV. This will demonstrate to the company that you are aware of the job’s criteria and that you possess the qualifications they are seeking in a candidate.

For instance, if you’re seeking a position in textile engineering, be sure to emphasize your familiarity with fabric testing, quality control, and textile production procedures. In your resume, if you’re searching for a position in computer engineering, be sure to emphasize your knowledge of coding languages and software development tools. 

Emphasize your understanding of project management, safety laws, and building materials when applying for positions in civil engineering.

Consider your accomplishments rather than just your work responsibilities.

Make careful to draw attention to particular accomplishments that showcase your talents and abilities while writing your resume and cover letter. Included here are any accomplishments that demonstrate your prospective worth to the company, such as projects you’ve finished, accolades you’ve won, or other recognition.

If you are a textile engineer, for instance, you may discuss a project where you improved the production procedure to decrease waste and boost efficiency. If you are a computer engineer, describe a project where you created new software that increased productivity or fixed a particular issue. Mention a project where you planned and managed the construction of a building or piece of infrastructure if you are a civil engineer.

Use the job description’s terms and phrases.

Many businesses analyze cover letters and resume for particular words and phrases using automated algorithms. Use keywords and phrases from the job description in your cover letter and CV to improve your chances of being found by these algorithms.

This will demonstrate to the company that you possess the abilities and credentials they are seeking.

Make sure to highlight your expertise with CAD software in your resume and cover letter, for instance, if the job description stresses the requirement for understanding of CAD software for textile engineering. Make sure to mention your experience with Java programming in your resume and cover letter if the job description highlights the requirement for Java programming skills for computer engineering. Make sure to indicate your familiarity with building codes in your resume and cover letter if the job description highlights the requirement for understanding building codes for civil engineers.

Draw attention to your soft abilities.

In addition to technical skills and qualifications, employers are also looking for candidates with strong soft skills. Soft skills are personal attributes that enable you to interact effectively with others and include skills like communication, teamwork, leadership, and problem-solving.

Make sure to highlight your soft skills in your resume and cover letter. For example, if you’re a textile engineer, mention your ability to work effectively in a team environment and your strong communication skills. If you’re a computer engineer, mention your ability to troubleshoot problems and your experience leading a team of developers. If you’re a civil engineer, mention your experience with project management and your ability to work under pressure.

Use a professional format and design.

Finally, make sure that your resume and cover letter have a professional format and design.

Highlight Your Technical Abilities: Demonstrating your technical abilities in your resume may have a big influence. Technical skills are essential for diploma engineers in Bangladesh. An architect, for instance, would promote their proficiency with AutoCAD, Revit, and SketchUp, whereas an automobile engineer might do so by highlighting their familiarity with automotive software like MATLAB and Simulink.

Display Your Professional Success: Employers in Bangladesh are interested in applicants who have contributed significantly to their prior businesses. For instance, civil engineers can discuss their involvement in the planning of a significant infrastructure project or their contribution to the creation of a new technology. These accomplishments can help you stand out from the competition and enhance your candidacy.

Employers in Bangladesh frequently use applicant tracking systems (ATS) to review resumes, so make use of the keywords from the job description. Include pertinent keywords from the job description in your resume and cover letter to boost your chances of being called in for an interview. An electrical engineer, for instance, may use the terms “power distribution,” “control systems,” and “circuit design” to highlight their proficiency.

Personalize Your Cover Letter and Resume: Employers in Bangladesh value candidates who take the time to tailor their application materials to the particulars of the position because every job application is different.

. For instance, a car engineer asking for a research and development post might emphasize their prototype and testing experience, whereas an architect engineer applying for a project management position can emphasize their leadership and organizational abilities.

Strong action verbs should be included in your resume and cover letter to demonstrate your abilities and expertise. Use stronger verbs like “designed,” “implemented,” and “managed” in place of weak verbs like “assisted” or “worked on.” A civil engineer, for instance, may use the action verb “oversaw” to indicate their function as a team leader of construction workers.

You may increase your chances of getting hired as a diploma engineer in Bangladesh by including these suggestions in your resume and cover letter, regardless of whether you have a professional background in architectural engineering, civil engineering, or car engineering.
