Computer-induced Medical Problems
Computer-induced health problems can be an umbrella term for the various problems a computer user can develop from extended and incorrect computer use. A computer user may experience many physical health problems from using computers extensively over a prolonged period in an inefficient manner. The computer user may have poor etiquette when using peripherals, for example incorrect posture. Reportedly, excessive use of electronic screen media can have ill effects on mental health related to mood, cognition, and behavior, even to the point of hallucination. Prevention methods include physical activity breaks, hydration, ergonomic posture, and regular eye exercises such as the 20-20-20 rule (every 20 minutes, look at something 20 feet or 6 meters away for 20 seconds). Common computer-induced medical problems Notable physical medical problems that can arise from using computers include carpal tunnel syndrome, computer vision syndrome, and musculoskeletal problems. Carpal tunnel synd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umbrella Term
In linguistics, semantics, general semantics, and ontologies, hyponymy () is a semantic relation between a hyponym denoting a subtype and a hypernym or hyperonym (sometimes called umbrella term or blanket term) denoting a supertype. In other words, the semantic field of the hyponym is included within that of the hypernym. In simpler terms, a hyponym is in a ''type-of'' relationship with its hypernym. For example, ''pigeon'', ''crow'', ''eagle'', and ''seagull'' are all hyponyms of ''bird'', their hypernym, which itself is a hyponym of ''animal'', its hypernym. Hyponyms and hypernyms Hyponymy shows the relationship between a generic term (hypernym) and a specific instance of it (hyponym). A hyponym is a word or phrase whose semantic field is more specific than its hypernym. The semantic field of a hypernym, also known as a superordinate, is broader than that of a hyponym. An approach to the relationship between hyponyms and hypernyms is to view a hypernym as consisting of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Email
Electronic mail (email or e-mail) is a method of exchanging messages ("mail") between people using electronic devices. Email was thus conceived as the electronic ( digital) version of, or counterpart to, mail, at a time when "mail" meant only physical mail (hence '' e- + mail''). Email later became a ubiquitous (very widely used) communication medium, to the point that in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. ''Email'' is the medium, and each message sent therewith is also called an ''email.'' The term is a mass noun. Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simu ...

Human Diseases And Disorders
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member. Anatomically modern huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human–computer Interaction
Human–computer interaction (HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people ( users) and computers. HCI researchers observe the ways humans interact with computers and design technologies that allow humans to interact with computers in novel ways. A device that allows interaction between human being and a computer is known as a "Human-computer Interface (HCI)". As a field of research, human–computer interaction is situated at the intersection of computer science, behavioral sciences, design, media studies, and several other fields of study. The term was popularized by Stuart K. Card, Allen Newell, and Thomas P. Moran in their 1983 book, ''The Psychology of Human–Computer Interaction.'' The first known use was in 1975 by Carlisle. The term is intended to convey that, unlike other tools with specific and limited uses, computers have many uses which often involve an open-ended dialogue between the user a ...

Screen Time
Screen time is the amount of time spent using a device with a screen such as a smartphone, computer, television, or video game console. The concept is under significant research with related concepts in digital media use and mental health. Screen time is correlated with mental and physical harm in child development. The positive or negative health effects of screen time are influenced by levels and content of exposure. To prevent harmful exposure to screen time, some governments have placed regulations on its usage. History Statistics The first electronic screen was the cathode ray tube (CRT), which was invented in 1897 and commercialized in 1922. CRT's were the most popular choice for display screens until the rise of liquid crystal displays (LCDs) in the early 2000s. Screens are now an essential part of entertainment, advertising, and information technologies. Since their popularization in 2007, smartphones have become ubiquitous in daily life. In 2019, 81% of American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ergonomic Hazard
Ergonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system. Ergonomic hazards include awkward postures, static postures, high forces, repetitive motion, or short intervals between activities. The risk of injury is often magnified when multiple factors are present. Factors such as whole-body or hand/arm vibration, poor lighting, poorly designed tools, equipment, or workstations all contribute to negative interactions with the worker/user. Some of the common body regions where injuries may occur include, but are not limited to: * Muscles or ligaments of the lower back. * Muscles or ligaments of the neck. * Muscles, tendons, or nerves of the hands/wrists. * Bones and muscles surrounding the knees and legs. Injuries in these and other parts of the body could result in Musculoskeletal Disorders (MSDs), which may be called Cumulative Trauma Disorders (CTDs) or Repetitive Strain Injuries (RSIs), and are estimated to account for about a ...

Depression (mood)
Depression is a mental state of low mood and aversion to activity, which affects more than 280 million people of all ages (about 3.5% of the global population). Classified medically as a mental and behavioral disorder, the experience of depression affects a person's thoughts, behavior, motivation, feelings, and sense of well-being. The core symptom of depression is said to be anhedonia, which refers to loss of interest or a loss of feeling of pleasure in certain activities that usually bring joy to people. Depressed mood is a symptom of some mood disorders such as major depressive disorder and dysthymia; it is a normal temporary reaction to life events, such as the loss of a loved one; and it is also a symptom of some physical diseases and a side effect of some drugs and medical treatments. It may feature sadness, difficulty in thinking and concentration and a significant increase or decrease in appetite and time spent sleeping. People experiencing depression may ...

Sleep Disturbances
A sleep disorder, or somnipathy, is a medical disorder of an individual's sleep patterns. Some sleep disorders are severe enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for diagnosing sleep disorders. Sleep disorders are broadly classified into dyssomnias, parasomnias, circadian rhythm sleep disorders involving the timing of sleep, and other disorders including ones caused by medical or psychological conditions. When a person struggles to fall asleep and/or stay asleep with no obvious cause, it is referred to as insomnia, the most common sleep disorder. Others include sleep apnea, narcolepsy and hypersomnia (excessive sleepiness at inappropriate times), sleeping sickness (disruption of sleep cycle due to infection), sleepwalking, and night terrors. Sleep disruptions can be caused by various issues, including teeth grinding (bruxism) and night terrors. Management of sleep disturbances t ...

Sleep Apnea
Sleep apnea, also spelled sleep apnoea, is a sleep disorder in which pauses in breathing or periods of shallow breathing during sleep occur more often than normal. Each pause can last for a few seconds to a few minutes and they happen many times a night. In the most common form, this follows loud snoring. There may be a choking or snorting sound as breathing resumes. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired during the day. In children, it may cause hyperactivity or problems in school. Sleep apnea may be either obstructive sleep apnea (OSA), in which breathing is interrupted by a blockage of air flow, central sleep apnea (CSA), in which regular unconscious breath simply stops, or a combination of the two. OSA is the most common form. OSA has four key contributors; these include a narrow, crowded, or collapsible upper airway, an ineffective pharyngeal dilator muscle function during sleep, airway narrowing during sleep a ...

Email Apnea
Email apnea is a term coined in 2007 by former Microsoft executive Linda Stone, meaning "a temporary absence or suspension of breathing, or shallow breathing, while doing email." Phenomenon Email apnea refers to the tendency to hold one's breath while engaging in email activities, a term derived from sleep apnea, which involves repeated interruptions in breathing during sleep. The term was coined by writer, speaker, and Microsoft executive Linda Stone. This phenomenon can exacerbate anxiety, as it often occurs during high-stress situations, leading to increased physical tension and mental strain. According to psychologists, high achievers and perfectionists are especially prone to email apnea due to a tendency to seek perfection in every email they send, which increases the stress around it and demands more focus. Email apnea can result in sleep disturbances, decreased energy levels, and heightened feelings of depression and anxiety. In 2007, Stone observed that she found hersel ...
