It alerts us to environmental threats serious enough that this generation may never regain the concentration it has lost. It explains how closely related information technology, stress, and health factors including diet are impairing our ability to focus. The book delves deeply into the issues of poor educational environments and associated concentration problems, prompting a…
I naturally followed the moment of death as if dreaming. The story began in a calm tone, bidding farewell to a person’s morning, which transitioned from brightness to a dark evening. It was not a typical death painted in the colors of a sunset sky followed by twilight, but his last moments shone hazily as…
The charm of studying abroad might be the opportunity to examine the underlying ideologies from the perspective of a third-country educational institution, looking at other countries. Especially for books belonging to categories not guaranteed diversity of thought due to seductive measures within certain regimes, a major benefit is the ability to look into the sensitive…
A classic in management that still receives acclaim 50 years later. The translator’s comment, likening it to Tchaikovsky’s Piano Concerto No. 1, profoundly resonated, capturing the true essence of a ‘classic.’ Just as one hopes to remember the lingering sensation of the concert hall’s air on their skin long after the movement ends, I hope…
ACT-Hand: Anatomical Correct Test-Bed Hand The human hand is a remarkable biological system, crucial for performing various tasks in our daily lives and mastering skilled activities. However, the limited understanding of its biomechanics and neuromuscular control has posed challenges for developing robotic hands and prosthetics that replicate its capabilities. Introducing the Anatomically Correct Test-Bed (ACT)…
Hydraulic Actuators for Rehabilitation-oriented Exoskeletons This study developed and evaluated two novel pneumatic actuators, LISPER and SCASPER, using kinematic and dynamic simulations and experiments. LISPER incorporates detailed bellow-shaped folds, meshes, and braces, while SCASPER achieves adjustable linearity output force/torque through modifications to the silicone rubber strip pattern. LISPER demonstrates excellent performance in range of…
A novel soft electromagnetic actuator (SEMA) designed for enhanced force-to-weight ratios and excellent actuation transparency, making it ideal for wearable haptic devices. This innovative SEMA integrates soft Halbach magnet arrays with multi-phase coils for effective Lorentz force generation, and uses ferrofluid in the air gap for improved bearing functionality and heat conduction. Key experiments have…
Multi-Modal Transforming Drone Arm (MMTDA): A versatile Solution for Aerial, Terrestrial, and Aquatic Environments 1. Introduction & Background of MMTDA Drones have been widely used in various industries, including aerial photography, surveillance, and surveying. However, as most drones are designed primarily for aerial operations, they are limited in their functionality, especially when it comes to…
Error Budgeting & Imaging Using Micro-Scale AFM 1. Overview This is a final project for Advanced Mechatronic II. Using a tapping mode macro-AFM which can track a sample in a vertical (z) position and moving stage in a horizontal (x-y) plane, an object can be sampled to acquire an image. This project involves error modeling…
The Dasan series by author Jo Yun-jae has become a scripture to me. It has been three years since I welcomed the New Year with my first work, adopting a posture of self-cultivation. Currently, I have read the “Study” segment eight times and the “Habits” segment four times, and have just started my first reading…
