Project Evolution and Environmental Awareness

On March 9, 2016, an activity was conducted to verify the fulfillment of goals regarding the use of resources. This involved a questionnaire aimed at reflecting on the awareness of environmental problem reduction and the importance of using natural resources and products responsibly. The reflection centered on four specific questions addressed to a workshop classmate.

First, the student reflected on whether they truly considered the importance of the correct use of natural resources and the products derived from them for environmental conservation. Second, specific actions were identified to modify daily life in the home, school, and community to reduce environmental impact. These actions include caring for water, not littering, and reusing materials whenever possible. Third, the student identified specific consumable materials used during the workshop activities that must be used appropriately, including paper, cardboard, glue, scissors, and colors. Finally, the student noted a change in perspective, concluding that caring for the environment is the responsibility of everyone.

Electronic Presentations and Microsoft PowerPoint Elements

An electronic presentation is defined as a digital information medium composed of slides, designed to expose and present information in a visual and attractive manner. These presentations contain various elements such as text, images, videos, audio, and animations with the objective of informing an audience. This topic includes several key components that facilitate understanding.

Slides are the individual "sheets" or pages of an electronic presentation where different segments of information are placed sequentially to explain a topic, making the content visual and clear. The text component consists of the written information, which should be brief and clear; it typically uses titles, subtitles, and keywords instead of long paragraphs. Visual elements include images, graphics, illustrations, tables, or icons that help explain information better and make the presentation attractive. Multimedia elements incorporate videos, audio, and music, which add dynamism to the exposition. The structure refers to the overall design and organization, including colors, fonts ($\text{typography}$), sizes, and the distribution of content to ensure it appears ordered. Hyperlinks are links that allow navigation to other slides, pages, or external documents to expand information easily.

Anatomy of the PowerPoint Interface

In the Microsoft PowerPoint workspace, several specific interface elements are utilized to manage and edit presentations. The primary components identified in the main screen include:

1. Ribbon (Cinta de opciones): The main toolbar containing most commands.
2. Tabs (Fichas o pestañas): Categories such as Insert, Design, and Animations.
3. Command Group (Grupo de comandos): Specific tools clustered within a tab.
4. Title Bar (Barra de título): Displays the name of the file.
5. Quick Access Toolbar (Barra de acceso rápido): Commonly used tools like Save.
6. Ribbon Display Options (Opciones de visualización de la cinta).
7. Search Box (Cuadro de búsqueda): Used to find specific commands or help.
8. Window Controls (Controles de ventana): Minimize, maximize, and close buttons.
9. Thumbnail View (Vista de diapositivas en miniatura): Preview of all slides on the left.
10. Slide Panel (Panel de diapositivas): The main work area for the current slide.
11. Placeholders (Marcadores de posición): Boxes in the slide for text or images.
12. Status Bar (Barra de estado): Shows current slide number and accessibility status.
13. Zoom Controls (Controles de zoom): Adjusts the magnification of the work area.
14. Presentation Views (Vistas de presentación): Options to change how the slide is viewed.
15. Notes Panel (Panel de notas): Area for adding speaker notes.

Communication Systems and Technical Language

Communication is defined as the process of transmitting information, ideas, feelings, or messages between two or more people. In the context of technological systems, it involves strategic thinking and creativity in problem-solving. It is essential to analyze the needs of the environment to plan a problem, research solution alternatives, and select the criteria that best adapt to contextual conditions.

The types of communication identified include verbal communication, written communication, and visual communication. The importance of communication lies in its ability to allow mutual understanding, enable self-expression, avoid misunderstandings, and facilitate organized processes. The evaluation of technical processes is a part of continuous improvement to achieve efficiency, efficacy ($\text{effectiveness}$), and feasibility in technical systems.

Elements and Evolution of Communication

The fundamental elements of the communication process are established as follows: The Sender is the one who sends the message (e.g., a person speaking or writing). The Receiver is the one who receives the message (e.g., the listener or reader). The Message is the specific content or idea being communicated (e.g., "hello" or a specific instruction). The Channel is the medium through which the message is sent (e.g., voice, cell phone, letter, or internet). The Code is the language or system of signs used (e.g., Spanish, emojis, or sign language). The Context is the situation or place where communication occurs (e.g., school, home, or with friends). Feedback (Retroalimentación) is the response or reaction of the receiver.

The history of communication follows a linear evolution:

1. Prehistory (before $3000\,BC$): Communication via gestures, sounds, signals, and cave paintings.
2. Ancient Age ($3000\,BC$ - $476\,AD$): Invention of writing, use of papyrus, hieroglyphics, and cuneiform writing.
3. Middle Ages ($476$ - $1453$): Communication through handwritten manuscripts and messengers; high control of information by the church.
4. $1450$: Invention of the printing press by Gutenberg, allowing faster book production and mass distribution of information.
5. 19th Century ($1800s$): Invention of the telegraph and Morse Code for long-distance messages.
6. $1876$: Invention of the Telephone, enabling real-time distance conversation.
7. 20th Century ($1900s$): Radio and Television for mass communication; 1969 saw the birth of the Internet for global communication.
8. 21st Century ($2000s$ - present): Social media, smartphones, and apps for immediate communication via WhatsApp, Instagram, etc.

Functions of Technical Communication

Technical communication is the clear, precise, and organized transmission of information regarding specialized topics such as science, technology, medicine, and instructions. It is critical because it avoids errors, saves time, facilitates learning, and improves teamwork. Key functions include:

Learning technical knowledge: Using specific texts and drawings (manuals and technical books) to transmit required knowledge to personnel. Production of techniques and processes: Graphically detailing how specific techniques or processes should be applied. Use of products: User manuals that accompany equipment to detail assembly, functions, and control usage for households or offices. Design and projection: Showing the parts and functions of a product during the development process to analyze performance or eliminate unnecessary steps.

Preventive Maintenance Instruction Manual

Maintaining a computer involves specific materials and a step-by-step procedure. Required materials include: microfiber cloth, canned compressed air, a soft brush, a low-pressure compressor ($\text{optional}$), isopropyl alcohol (minimum $70\%$), cotton swabs (tips), a screwdriver set (primarily Phillips), and an antistatic bracelet ($\text{recommended}$).

The procedure is as follows:

1. Power off and disconnect the computer and remove the battery if it is a laptop.
2. Clean the external surfaces (screen, keyboard, and case) with the microfiber cloth and alcohol applied to the cloth, not the device.
3. Carefully open the equipment case or laptop covers.
4. Use compressed air to remove interior dust from fans, heat sinks, and cards; use the brush for difficult areas but never blow with your mouth due to moisture.
5. Clean components carefully with swabs and isopropyl alcohol if stuck dirt is present.
6. Perform a general review to check cable connections and ensure fans spin freely.
7. Close the equipment and reconnect.

Flowcharts and Logical Processes

A flowchart (diagrama de flujo) is the graphical representation of a sequence of steps, processes, algorithms, or systems. It uses standardized symbols connected by arrows to show direction. The basic symbols are:

• Oval: Start/End (defines process limits).
• Rectangle: Process (represents an activity or action).
• Rhombus: Decision (indicates a branch point, usually Yes/No).
• Arrows: Flow lines (connect symbols in sequential order).
• Document: Indicates input or output of a report.

An example of a flowchart application is the process of completing a stickers album: Start -> Do you have the album? (No: Buy Panini album -> Buy sticker packs) -> (Yes: Open packs) -> Review stickers -> Do you already have the sticker? (Yes: Interchange repeated ones with friends) -> (No: Glue into album) -> Is it complete? (No: Buy more stickers) -> (Yes: Finish).

Technical Language Consensus and Excel Basics

Technical language develops through dialogue and consensus across communities. In informatics, terms like "Software" refer to sets of instructions that make hardware work, while "Hardware" refers to the physical physical parts of a computer. Memory RAM is a technical term for random access memory that aids performance. Other technical terms include CPU (processor), operating system, and connectivity descriptors like "Nitidity."

Excel formulas are operations used to perform calculations automatically within a spreadsheet. Formulas always begin with the equal sign ($=$). Advantages include time-saving, error reduction compared to manual operations, automatic updates when data changes, and the ability to organize large quantities of information. An example formula is: $=SUMA(A1:A5)$

Communication in the Office and Customer Service

Communication in professional settings is essential for organizing work, improving the labor environment, and making decisions. Poor communication leads to misunderstandings, errors, and an unmotivated team. Modern office communication utilizes email and messaging, requiring skills in both clear expression and active listening.

In customer service, the correct use of language and specific telephone etiquette is vital for business success. Companies must train personnel to use harmonious voices and clear diction. Communication—whether written, graphic, internal, or external—helps the public form an image of the company. Personnel must have the capacity to bridge the gap between the "expected service" and the "received service" by understanding and addressing user inquiries effectively.
