PFD Allowance
PFD allowance in work systems is the adjustment done to the normal time to obtain the Standard time (manufacturing), standard time for the purpose of recovering the lost time due to personal needs, fatigue, and unavoidable delays. By providing a small increase to the normal time in each cycle, a worker can still be able to cover lost time and complete the work assigned to him or her. Allowance technique There are two types of interruption: (1) interruption related to work (2) interruption not related to work. For example, a machine breakdown, rest break to overcome fatigue, and receiving Teacher, instruction from the manager are the interruption related to work, but personal needs, lunch breaks, and personal telephone calls are interruptions not related to work. However, the two types of interruption are both essential for the worker because it is almost impossible to work continually during a regular shift. Personal needs, fatigue, and unavoidable delays allowance The standard time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Time (manufacturing)
In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may occur but have not been observed. Standard time = normal time + allowance Where; Normal time = average time × rating factor (take rating factor between 1.1 and 1.2) Usage of the standard time Time times for all operations are known. * Staffing (or workforce planning): the number of workers required cannot accurately be determined unless the time required to process the existing work is known. * Line balancing (or production leveling): the correct number of workstations for optimum work flow depends on the processing time, or standard, at each workstation. * Materials requirement planning (MRP): MRP systems cannot operate properly without ...

Fatigue
Fatigue describes a state of tiredness that does not resolve with rest or sleep. In general usage, fatigue is synonymous with extreme tiredness or exhaustion that normally follows prolonged physical or mental activity. When it does not resolve after rest or sleep, or occurs independently of physical or mental exertion, it may be a symptom of a medical condition that may become severe or progressive. Fatigue can be a feature of a mental disorder such as depression; may be associated with conditions of chronic pain such as fibromyalgia; it may also feature in conditions of chronic low-level inflammation, and be a disease-related symptom in many other conditions. Fatigue often has no known cause, and is recognised as being very complex in nature. Fatigability describes a susceptibility to fatigue. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of cognitive activity which impairs cognitive abil ...

Rest Break
A break at work (or work-break) is a period of time during a shift in which an employee is allowed to take time off from their job. It is a type of downtime. There are different types of breaks, and depending on the length and the employer's policies, the break may or may not be paid. Meal breaks, tea breaks, coffee breaks, or lunch breaks usually range from ten minutes to one hour. Their purpose is to allow the employee to have a meal that is regularly scheduled during the work day. For a typical daytime job, this is lunch, but this may vary for those with other work hours. Lunch breaks allow an employee's energy to replenish. It is not uncommon for this break to be unpaid, and for the entire work day from start to finish to be longer than the number of hours paid in order to accommodate this time. Break laws Modern break laws in the United States stem from labor laws passed between 1935 and 1974. It was during this time that jobs in the U.S. modernized and the country's ...

Teacher
A teacher, also called a schoolteacher or formally an educator, is a person who helps students to acquire knowledge, competence, or virtue, via the practice of teaching. ''Informally'' the role of teacher may be taken on by anyone (e.g. when showing a colleague how to perform a specific task). In some countries, teaching young people of school age may be carried out in an informal setting, such as within the family (homeschooling), rather than in a formal setting such as a school or college. Some other professions may involve a significant amount of teaching (e.g. youth worker, pastor). In most countries, ''formal'' teaching of students is usually carried out by paid professional teachers. This article focuses on those who are ''employed'', as their main role, to teach others in a ''formal'' education context, such as at a school or other place of ''initial'' formal education or training. Duties and functions A teacher's role may vary among cultures. Teachers may provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telephone Call
A telephone call is a connection over a telephone network A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more ... between the called party and the calling party. First telephone call The first telephone call was made on March 10, 1876, by Alexander Graham Bell. Bell demonstrated his ability to "talk with electricity" by transmitting a call to his assistant, Thomas Watson. The first words transmitted were "Mr Watson, come here. I want to see you." This event has been called Bell's "greatest success", as it demonstrated the first successful use of the telephone. Although it was his greatest success, he refused to have a telephone in his own home because it was something he invented by mistake and saw it as a distraction from his main studies.

Public Toilet
A public toilet, restroom, public bathroom or washroom is a room or small building with toilets (or urinals) and sinks for use by the general public. The facilities are available to customers, travelers, employees of a business, school pupils and prisoners and are commonly sex segregation, separated into male and female toilets, although unisex toilet, some are unisex, especially for small or single-occupancy public toilets. Increasingly, accessible toilet, public toilets are accessible to people with disabilities. Depending on the culture, there may be varying degrees of separation between males and females and different levels of privacy. Typically, the entire room, or a stall or cubicle containing a toilet, is lockable. Urinals, if present in a male toilet, are typically mounted on a wall with or without a divider between them. local authority, Local authorities or commercial businesses may provide public toilet facilities.

Water Fountain
A drinking fountain, also called a water fountain or water bubbler, is a fountain designed to provide drinking water. It consists of a basin with either continuously running water or a tap. The drinker bends down to the stream of water and swallows water directly from the stream. Modern indoor drinking fountains may incorporate filters to remove impurities from the water and chillers to lower its temperature. Drinking fountains are usually found in public places, like schools, rest areas, libraries, and grocery stores. Many jurisdictions require drinking fountains to be wheelchair accessible (by sticking out horizontally from the wall), and to include an additional unit of a lower height for children and short adults. The design that this replaced often had one spout atop a refrigeration unit. History Before potable water was provided in private homes, water for drinking was made available to citizens of cities through access to public fountains. Many of these early public ...

Cognitive Function
Cognitive skills, also called cognitive functions, cognitive abilities or cognitive capacities, are brain-based skills which are needed in acquisition of knowledge, manipulation of information and reasoning. They have more to do with the mechanisms of how people learn, remember, solve problems and pay attention, rather than with actual knowledge. Cognitive skills or functions encompass the domains of perception, attention, memory, learning, decision making, and language abilities. Specialisation of functions Cognitive science has provided theories of how the brain works, and these have been of great interest to researchers who work in the empirical fields of brain science. A fundamental question is whether cognitive functions, for example visual processing and language, are autonomous modules, or to what extent the functions depend on each other. Research evidence points towards a middle position, and it is now generally accepted that there is ''a degree'' of modularity in aspect ...

Eye Strain
Eye strain, also known as asthenopia (from Greek ''a-sthen-opia'', grc, ἀσθενωπία, ), is a common eye condition that manifests through non-specific symptoms such as fatigue, pain in or around the eyes, blurred vision, headache, and occasional double vision. Symptoms often occur after long-term use of computers, digital devices, reading or other activities that involve extended visual tasks which are broadly classified into external and internal symptom factors. When concentrating on a visually intense task, such as continuously focusing on a book or computer monitor, the ciliary muscles and the extraocular muscles are strained. This causes discomfort, soreness or pain on the eyeballs. Closing the eyes for ten minutes and relaxing the muscles of the face and neck at least once an hour usually relieves the problem. A page or photograph with the same image twice, but slightly displaced (from a printing mishap, a camera moving during the shot, etc.) can cause eye strai ...

Lighting
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects. History With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 years ago, fire was kindl ...
