Therbligs -- an Innovation of the Past Assembly Line With Still-Practical Applications Today
What is the problem; one might be tempted to ask, with apportioning the workday according to simple units of seconds and hours, when measuring worker efficiency? Why is there a need to create another system of measurement in respect to motion as well as to time? The concept of Therbligs a study of worker efficiency not in relation to time, but in relation to motion, provides the answer.
The concept of Therbligs was born during the turn of the 20th century, a century that oversaw the birth of the modern factory and also the modern motion picture. It was with the help of this latter invention that John and Lillian Galbraith could embark upon their study of human kinesthetic behavior in the former. Thus, although term "Therbligs" may "sound like a new computer term or some obscure part of the human anatomy," these Therbligs in fact comprise a fairly old system for analyzing the motions involved in performing a task, almost as old as the modern industrial age of assembly lines. The Gilbraiths' identification of and isolation of individual worker motions,...

Thus concept of the Therblig was born around 1908 and it is constantly being refined and tested by ergonomics experts even today. The concept's birth was generated by the enabling of systematic motion study to take place by using micro-motion stop study of movie film. The Gilbreths were able to examine the smallest of motions by watching filmed depictions of workers. Then, they isolated the individual motions and plotted such "Therbligs" on a Simo Chart (Simultaneous Motion Chart) along with the time each motion took. "The sequences of motions of each hand were plotted, as was a foot, if used for pedal controls. Then, by examining the charts, one could determine which Therbligs were taking too long. One could also isolate individual motions that could be eliminated by rearranging the step-by-step procedures of the work. (Ferguson, 2000) Through the use of such study, the Gilbreths identified periods of delay caused be either the tool and part layout,…

ANATOMY Anatomy: Special SensesPrompt 1The human body has two senses types: special and general. Special senses include various body organs to feel the surroundings, for example, balancing, seeing, tasting, and smell, whereas general senses are only related to touch (Miller, 2020). The sensory data that the brain receives is collected by the skin that touches the objects. The general senses encompass pain, pressure, vibration, and proprioception. For instance, if we
Menopause: A Short History From Human Anatomy and Physiology, Spence and Mason, 2nd Edition from 1983, comes this description of Menopause. At about age 50, the ovarian and menstrual cycles gradually become irregular. Ovulation fails to occur during many of the irregular cycles and in most women the cycles cease altogether over the next several months or at most, a few years. The cessation of the menstrual cycle is referred to as
Anatomy Major cavities of the body and their organs: Our body is made up of solid structures and many cavities. The organs are packed in these cavities and they fill these cavities. The major cavities in our body are: the ventral cavity, which is surrounded by the rib cage and the abdominal musculature and dorsal cavity, which is surrounded by the bones of the skull and vertebral column.

). These complications will be discussed in the discussion section of this paper. Discussion Taking into account the physiological functioning of these bacteria on the human sensory and muscles muscle system it becomes clear that that this can be a serious threat to human health and, as discussed above, this disease can lead to death. Modern medicine has however created an antidote to the effects of this disease. Tetanus can be prevented
Human-Equipment Interface Technological transformations have brought widespread use of machines and tools to the work setting. Owing to this, such concepts as human-machine/equipment interfaces have become increasingly prominent. In its simplest form, human-machine interface (HMI) refers to the point or extent of interaction between a machine and its operator; taken literally, it is the area of the machine and that of the human that interact during the execution of a task.
