control

Etymology: Fr, controler, to register

1 v, to exercise restraint or maintain influence over a situation, as in self-control, the conscious limitation or suppression of impulses.

2 n, a standard against which conclusions may be measured, as in a "control group."

control [kon-trōl´]

1. the governing or limitation of certain objects, events, or physical responses.

2. a standard against which experimental observations may be evaluated, as a procedure identical to the experimental procedure except for the absence of the one factor being studied.

3. conscious restraint and regulation of impulses and suppression of instincts and affects.

4. a patient or group differing from the case or treated group under study by lacking the disease or by having a different or absent treatment or regimen. The controls and subjects usually otherwise have certain similarities to allow or enhance comparison between them.

automatic brightness control an automated exposure device used in radiology; it senses light and adjusts itself to produce a predetermined fluoroscopic density.

automatic exposure control a timer by which the exposure of x-ray film is determined by the radiographer but the length of exposure is determined by the equipment.

aversive control in behavior therapy, the use of unpleasant stimuli to change undesirable behavior.

birth control see birth control.

hemorrhage control in the nursing interventions classification, a nursing intervention defined as reduction or elimination of rapid and excessive blood loss.

infection control see infection control.

infection control: intraoperative in the nursing interventions classification, a nursing intervention defined as preventing nosocomial infection in the operating room.

motor control the generation and coordination of movement patterns to produce function; it may either control movements of the body in space or stabilize the body in space. See also postural control.

postural control motor control that stabilizes the body in space by integrating sensory input about body position (somatosensory, visual, and vestibular input) with motor output to coordinate the action of muscles and keep the body's center of mass within its base of support. An important aspect of postural control is the righting reactions. Called also balance.

stimulus control any influence exerted by the environment on behavior.

control,

n 1. power to direct the outcome of events that occur throughout life. To develop effective problem-solving skills and strategies, one must specifically differentiate between the circumstances that can and cannot be personally managed. For instance, one can direct the events associated with a work but not the outcome of a surgery. In behavioral medicine, it is one of the three unique attitudes associated with stress hardiness.
2. comparison standard as part of comparative test design.
3. the group selected for comparison to a test group in order to assess a hypothesis. See also stress hardiness.

control

1. the governing or limitation of certain objects or events.

2. a standard against which experimental observations may be evaluated, as a procedure identical to the experimental procedure except for the one factor being studied; a requirement of any planned experimental study. Also, any individual of the group exhibiting the standard characteristics.

disease control

restraining or reducing the prevalence of individual disease. Includes the range of strategies from limitation of occurrence to eradication. Implies legislative control of notifiable disease.

control elements

nucleotide sequences on DNA that usually precede (upstream) the sequences coding for the structural gene at which regulator proteins act.

control factor

in a comparison between diseases caused by a number of contributing factors it may be necessary to supply controls for one or more of these factors.

control group

the group of animals with which the experimental group is to be matched; the group which has not had its variables manipulated experimentally. The selection of the animals to be included in the two groups may be based on matching them with respect to age, to their history of nutrition or inheritance, or vaccination or prophylactic treatment. Called also controls.

ovulation control

prevention of ovulation by administration of progesterone or stimulation of ovulation by injection of follicle-stimulating hormone are examples.

paired control

comparison between the experimental and control groups is most accurate if the control animal for each experimental animal is selected to be as similar as possible, i.e. a paired control.

control pole

a pole with a noose at the end used to catch and restrain small animals.

control population

a large control group.

population control

a variety of techniques are used with contraception being least used. Permanent surgical interference is common in food, racing and companion animal groups, and termination of pregnancy and estrus synchronization, both by hormonal means, are also extensively practiced. Increasing the culling rate is the standard procedure for dealing with a feed shortage.

x-ray control unit

the controlling mechanisms in an x-ray machine. Include the voltmeter and voltage compensator control, the kilovoltage, milliameter and milliamperage selectors and the timer and exposure control button.

control

Clinical research Control subject A nontreated or 'negative' individual in a study who serves as a reference. See Concurrent nonrandomized control, Control population, Control subject, Historical control Epidemiology In a case-control study, a comparison group of persons without disease Lab medicine A specimen with known or standardized values for an analyte, that is processed in tandem with an unknown specimen; the 'control' specimen is either known to have the substance being analyzed, ie 'positive' control or known to lack the substance of interest, ie 'negative' control. See Negative control, Positive control, Quality control Psychology The degree to which a person can limit or modify verbal or physical responses to external stimuli. See Administrative control, Impulse control.

They also wanted me to go for uvb lights which are knowen to treat psriosis, which personalyy i dont feel it helps me ..realie.. eczema and psriosis are 2 totally diff skin diseases.. someone . PLEASEE HELP .. : )

A. this actualy works.. one tsp. of apple cider vinegar per day diluted in alot of water or apple juice. my son who is 3 yrs. old had horrible sores from ecsima and it was cleared up within 2 wks. he had been struggling with the condition his whole life and now he has been clear for 6mos. topically applied it burns like hell so dont apply it topically untill after the first week of treatment with dilution of water taken internally. by then the sores and itching should be gone..
don't do steroide cream unless necessary, the side affects greatly out weigh the potential good. i sincerely hope this helps you. let me know..
