Health
Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a broader sense in its 1948 constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies and because of the problem created by use of the word "complete", which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.
Methodology
Methodology is the systematic, theoretical analysis of the methods applied to a field of study. It comprises the theoretical analysis of the body of methods and principles associated with a branch of knowledge. Typically, it encompasses concepts such as paradigm, theoretical model, phases and quantitative or qualitative techniques.
Safety
Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
Manager
As far as possible the duty of a leader is to foresee dissatisfaction and to remedy injustice before complaints are made. To accomplish this he must maintain close contact with the men he controls. Let him go into the trenches if he is a general; let him arrive at the factory with his workmen now and then if he is the manager. He must have some imagination; an understanding of other men's lives is necessary to him, so that he may be able to protect those under him from unnecessary suffering. The secret of gaining their affection is to feel affection for them and to be able to do their jobs as well as they do them themselves. Men endure taking orders, and even like it, if the orders are given intelligently.
