The “Walk & Flip” Innovation in Reading & Exercise

The “Walk & Flip”: The Formation of an Innovative Approach to Reading & Exercise

Research paper submitted by Ryan Ting, Lab Intern and graduating senior at BASIS DC High School.

Introduction

I like to read as much as I can. Furthermore, as a high school student, I often have to read — reading textbooks to prepare for lessons, reading novels for literature classes, etc. I also like to exercise, which includes cardio exercises using a treadmill. When I walk on the treadmill, I often listen to audiobooks or watch videos. I rarely read. There lies the conflict. Reading physical books is difficult, especially when walking on a treadmill. Being at a different speed than the book means flipping pages often leads to ripping them out. Even worse, reaching out to carefully flip a page may lead to a lapse of focus on walking — subsequently falling and being injured. 

Literature Review

In the United States, 80% of people aged 6 years and older fail to perform enough exercise (Piercy, 2018). To get more exercise, many use treadmills. However, many also choose to watch screens for entertainment as they use treadmills. Excessive screen time is linked to poor sleep quality, stress regulation, and mental health (Nakshine, 2022). Therefore, there is value in discovering options for screenless entertainment.

Reading is a means of screenless entertainment, but is inconvenient because the book may not be supported by the treadmill and the act of flipping pages may lead to page tears because the reader is in motion while the book is stationary. Even worse, trying to slow down one’s walking speed to carefully flip a page may lead to falls and injury. 

The solution described below includes a shelf to hold the book in place, a system of servo motors to flip the pages automatically, and a hands-free trigger to flip the pages when the reader is done. The device is unlike

Innovations in Posture Correction

Revolutionizing Posture: The micro:bit Posture Tracker 

Jayden Adomako, Stafford County High School

    Many of us spend a lot of time sitting with poor posture, whether at work desks, using our phones for browsing, or watching TV. In all of these, we're likely to be slumped with our neck pushing our head forward, which can cause various body aches and pains, especially in our back and neck. The World Health Organization reported that over 1.7 billion people suffer from problems affecting their muscles, bones, and joints (WHO, 2021). This blog post is a first step in helping yourself or others to learn how to sit and stand correctly to avoid future posture-related problems.

What is Good Posture?

    Good posture refers to the alignment of the body, and particularly in the spine. Good posture allows for optimal functioning of muscles and joints, or what a teacher or medical professional would have you call the musculoskeletal system. Perfect posture is uncommon or rare, but would involve positioning the body in a way that minimizes strain and maximizes the efficiency of movements of your body. In standing posture, the ears, shoulders, and hips should ideally align vertically, with the body weight distributed evenly on both legs. When sitting, the spine should be in a relatively neutral position, with the lower back also supported. Your feet should also be flat on the floor, and knees at a 90 degree angle. These positions help reduce the risk of strain and discomfort and prevent long term musculoskeletal issues (Gorman et al., 2020).

The Problem with Poor Posture

    Correct posture is something that many individuals struggle with nowadays, often without realizing it. The dependency on today's technology in the modern world makes slouching hard to avoid, Whether it be at work, school, or simply at home after a long day. These slouching habits creep up on everyone, and it can lead to discomfort usually in the back area, pain, and in decreased productivity. O'Keeffe et al. (2019), reported that 80% of people who have claimed to have poor posture have also experienced chronic pain or discomfort. Other research supports this connection with poor posture and musculoskeletal pain.

The Invention: A micro-bit-Powered Posture Tracker

    My innovative wearable technology offers a non-invasive way for people to position themselves for alignment on a daily basis.My engaging invention is a wearable device created to assist in keeping the posture of your spine in check by detecting your body position in real time. It features and is powered by the micro-bit microcontroller. The micro-bit is a nice compact, inexpensive  piece of technology that integrates a sensor and can be programmed in

The Effect of Leading Edge Slot Angle on NACA 2412 Airfoil’s Critical Angle of Attack

by Ian A. Ledford

Introduction

An aerodynamic stall occurs when the critical angle of attack is surpassed, producing insufficient lift for flight. They continue to be a significant, often disastrous problem in modern aviation. STAT Over the past few decades, several technologies have been developed in an effort to reduce the number of stalls that occur. On the leading edge of an airfoil, movable slats can both increase the camber of the airfoil and direct high pressure air towards the upper surface to delay boundary layer separation at higher angles of attack (AOA’s). Still, like most control surfaces, slats increase drag thus reducing efficiency so they are designed to retract. Unfortunately, these retracting systems add weight, potential for failure, and complexity in manufacturing.

Leading edge (fixed) slots apply the same principles as movable slats but cannot retract. Their simplicity solves the issues with slats outlined above, but they have no way of reducing the drag they create. This investigation will determine the best angle for a leading edge slot to improve an airfoil's lift at higher angles of attack, potentially delaying the onset of a stall.

Theory

Fluid traveling closely to an object is subject to the no-slip condition (the fluid has zero velocity relative to the object) because of the high decelerating effects from its viscosity. Farther away from the

Cybersecurity Threats in the Hospitality

 

The Hidden Dangers: Real Life Examples of How Cybersecurity Threats in the Hospitality Industry Affect More than Just Personal Information

By: Nathan Km

In our increasingly interconnected world, cybersecurity threats remain a formidable challenge for businesses across all sectors. The hospitality industry has seen a rising number of cyberattacks that disrupt operations, compromise sensitive data, and damage reputations. From ransomware attacks to data breaches, these threats can cripple critical systems like reservation platforms and electronic key card systems, causing significant operational and financial repercussions.

The Mechanics of Cyber Attacks

Cybersecurity threats typically exploit vulnerabilities in a company's network or software. These vulnerabilities can arise from outdated systems, inadequate security measures, or human error. Common attack vectors include phishing emails, which trick employees into revealing sensitive information or hyperlinks or attachments that install malicious software, and ransomware, which encrypts a company's data until a ransom is paid. Once attackers gain access, they can disrupt operations, steal data, or hold systems hostage, leading to widespread chaos and substantial financial loss.

Example 1: MGM Resorts Cybersecurity Incident

The 2023 MGM Resorts systems attack is a high-profile example of a cybersecurity attack in the hospitality industry in which a cybersecurity issue led to the shutdown of many systems including its website, reservation systems, booking systems, hotel electronic key card systems, and casino floor operations. The company's email systems were also affected.

The attack had far-reaching consequences. Guests were unable to make or manage reservations, leading to lost
