Checklists
A checklist is a type of job aid used in repetitive tasks to reduce failure by compensating for potential limits of human memory and attention. It helps to ensure consistency and completeness in carrying out a task. A basic example is the "to do list". A more advanced checklist would be a schedule, which lays out tasks to be done according to time of day or other factors. A primary task in checklist is documentation of the task and auditing against the documentation. Use of a written checklist can reduce any tendency to avoid, omit or neglect important steps in any task. Applications *aid in aviation safety to ensure that critical items are not overlooked. Example: Pre-flight checklists * Used in quality assurance of software engineering, to check process compliance, code standardization and error prevention, and others. * Often used in industry in operations procedures * In civil litigation to deal with the complexity of discovery and motions practice. An example is the open ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pre-flight Checklist
In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no important tasks are forgotten. Failure to correctly conduct a preflight check using a checklist is a major contributing factor to aircraft accidents. History According to researcher and writer Atul Gawande, the concept of a pre-flight checklist was first introduced by management and engineers at the Boeing Company following the 1935 crash of the prototype Boeing B-17 (then known as the Model 299) at Wright Field in Dayton, Ohio, killing both pilots. Investigation found that the pilots had forgotten to disengage the crucial gust locks (devices which stop control surfaces moving in the wind while parked) prior to take-off. ''Life'' magazine published the resulting lengthy and detailed B-17 checklist in its 24 August 1942 issue. Crashes attributed to checklist failures * On December 26, 1968, Pan Am Flight ...

WHO Surgical Safety Checklist
The World Health Organization (WHO) published the WHO Surgical Safety Checklist in 2008 in order to increase the safety of patients undergoing surgery. The checklist serves to remind the surgical team of important items to be performed before and after the surgical procedure in order to reduce adverse events such as surgical site infections or retained instruments. It is one affordable and sustainable tool for reducing deaths from surgery in low and middle income countries. Several studies have shown the checklist to reduce the rate of deaths and surgical complications by as much as one-third in centres where it is used. While the checklist has been widely adopted due to its efficacy in many studies as well as for its simplicity, some hospitals still struggle with implementation due to local customs and to a lack of "buy-in" from surgical staff. Background In 2004, the World Health Assembly (WHA) founded the WHO Patient Safety international alliance in order to tackle issues of ...

Diving Safety
Diving safety is the aspect of underwater diving operations and activities concerned with the safety of the participants. The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short-term survival. Other equipment allows the diver to operate in relative comfort and efficiency, or to remain healthy over the longer term. The performance of the individual diver depends on learned skills, many of which are not intuitive, and the performance of the team depends on competence, communication, attention and common goals. There is a large range of hazards to which the diver may be exposed. These each have assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Checkbox2
A checkbox (check box, tickbox, tick box) is a graphical widget that permits the user to make a binary choice, i.e. a choice between one of two possible mutually exclusive options. For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes/no question. Checkboxes are shown as ☐ when unchecked, or ☑ or ☒ (depending on the graphical user interface) when checked. A caption describing the meaning of the checkbox is normally shown adjacent to the checkbox. Inverting the state of a checkbox is done by clicking the mouse on the box, or the caption, or by using a keyboard shortcut, such as the space bar. Often, a series of checkboxes is presented, each with a binary choice between two options. Then the user may select several of the choices. Contrasting is a radio button, in which only a single option is selectable from several mutually-exclusive choices. Checkboxes may be disabled (indicated "greyed out") to inform the user of their existen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technical Diving
Technical diving (also referred to as tec diving or tech diving) is scuba diving that exceeds the agency-specified limits of recreational diving Recreational diving or sport diving is diving for the purpose of leisure and enjoyment, usually when using scuba equipment. The term "recreational diving" may also be used in contradistinction to "technical diving", a more demanding aspect of ... for non-Professional diver, professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to a greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment often involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources. The popularisation of the term ''technical diving'' has been credi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Checksum
A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. The procedure which generates this checksum is called a checksum function or checksum algorithm. Depending on its design goals, a good checksum algorithm usually outputs a significantly different value, even for small changes made to the input. This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted. Checksum functions are related to hash functions, fingerprints, randomization functions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Check Sheet
The check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative. When the information is quantitative, the check sheet is sometimes called a tally sheet. The check sheet is one of the so-called Seven Basic Tools of Quality Control. Format The defining characteristic of a check sheet is that data are recorded by making marks ("checks") on it. A typical check sheet is divided into regions, and marks made in different regions have different significance. Data are read by observing the location and number of marks on the sheet. Check sheets typically employ a heading that answers the Five Ws: * Who filled out the check sheet * What was collected (what each check represents, an identifying batch or lot number) * Where the collection took place (facility, room, apparatus) * When the collection took place (hour, shift, day of the week) * Why the data were collected.

Common Sense
''Common Sense'' is a 47-page pamphlet written by Thomas Paine in 1775–1776 advocating independence from Great Britain to people in the Thirteen Colonies. Writing in clear and persuasive prose, Paine collected various moral and political arguments to encourage common people in the Colonies to fight for egalitarian government. It was published anonymously on January 10, 1776, at the beginning of the American Revolution and became an immediate sensation. It was sold and distributed widely and read aloud at taverns and meeting places. In proportion to the population of the colonies at that time (2.5 million), it had the largest sale and circulation of any book published in American history. As of 2006, it remains the all-time best-selling American title and is still in print today. ''Common Sense'' made public a persuasive and impassioned case for independence, which had not yet been given serious intellectual consideration. Paine connected independence with common dissenting P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time-critical
A window of opportunity (also called a margin of opportunity or critical window) is a period of time during which some action can be taken that will achieve a desired outcome. Once this period is over, or the "window is closed", the specified outcome is no longer possible. Examples Examples of windows of opportunity include: *The critical period in neurological development, during which neuroplasticity is greatest and key functions, such as imprinting and language, are acquired which may be impossible to acquire at a later stage *The golden hour or golden time, used in emergency medicine to describe the period following traumatic injury in which life-saving treatment is likely to be successful * Market opportunities, in which one may be positioned to take advantage of a gap in a particular market, the timing of which may depend on the activities of customers, competitors, and other market context factors *Planting and harvesting seasons, in agriculture, which are generally ti ...

Checkmark
A check or check mark (American English), checkmark (Philippine English), tickmark (Indian English) or tick (Australian, New Zealand English, and British English) is a mark (✓, ✔, etc.) used, primarily in the English-speaking world, to indicate the concept "yes" (e.g. "yes; this has been verified", "yes; that is the correct answer", "yes; this has been completed", or "yes; this tem or optionapplies"). The x mark is also sometimes used for this purpose (most notably on election ballot papers, e.g. in the United Kingdom), but otherwise usually indicates "no", incorrectness, or failure. One of the earliest usages of a check mark as an indication of completion is on ancient Babylonian tablets "where small indentations were sometimes made with a stylus, usually placed at the left of a worker's name, presumably to indicate whether the listed ration has been issued." As a verb, to check (off) or tick (off) means to add such a mark. Printed forms, printed documents, and computer s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
