(1) physiological needs. This is the survival of human beings to maintain the most basic requirements, including hunger, thirst, clothing, shelter, sexual demands. If these needs are not met, the survival of humanity became a problem. In this sense, the physical needs is to promote the movement of people and the most powerful driving force. Maslow believed that only those most basic needs met to the extent necessary to survive, the other needs to become the new incentives, but by this time, to meet the needs of these has been relatively no longer a motivating factor in . (2) safety needs. This is mankind's quest to protect their own safety, get rid of the cause and loss of property, threats, to prevent the invasion of occupational contact with the harsh supervision needs. Maslow believes that the pursuit of the whole organism is a security mechanism, the human receptors, effector organ, intelligence and other energy is mainly a tool for seeking security, or even science and philosophy of life is to meet the security needs are seen as part of it. Of course, when such a need, once a relatively met, it would no longer be a motivating factor. Do not machine translation, using this as accurately as possible (1) physiological needs.
