Nursing
Nursing is a profession within the health care sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health andquality of life.
Nurses may be differentiated from other health care providers by their approach to patient care, training, and scope of practice. Nurses practice in a wide diversity of practice areas with a different scope of practice and level of prescriber authority in each. Many nurses provide care within the ordering scope of physicians, and this traditional role has come to shape the historic public image of nurses as care providers. However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level. In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.
The American Nurses Association (ANA) states nursing is the protection, promotion, and optimization of health and abilities, prevention of illness and injury, alleviation of suffering through the diagnosis and treatment of human response, and advocacy in the care of individuals, families, communities, and populations.
Public health
Public health is "the science and art of preventing disease, prolonging life and promotinghealth through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to health based on population health analysis. The population in question can be as small as a handful of people, or as large as all the inhabitants of several continents (for instance, in the case of apandemic). The dimensions of health can encompass "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity", as defined by the United Nations' World Health Organization. Public health incorporates the interdisciplinaryapproaches of epidemiology, biostatistics and health services. Environmental health,community health, behavioral health, health economics, public policy, insurance medicineand occupational health (respectively occupational medicine) are other important subfields.
The focus of public health intervention is to improve health and quality of life through the prevention and treatment of disease and other physical and mental health conditions, through surveillance of cases and health indicators, and through the promotion of healthy behaviors. Promotion of hand washing and breastfeeding, delivery of vaccinations, and distribution of condoms to control the spread of sexually transmitted diseases are examples of common public health measures.
Modern public health practice requires multidisciplinary teams of professionals includingphysicians specializing in public health/community medicine/infectious disease,epidemiologists, biostatisticians, public health nurses, medical microbiologists, environmental health officers / public health inspectors,pharmacists, dental hygienists, dietitians and nutritionists, veterinarians, public health engineers, public health lawyers, sociologists, community development workers, communications experts, and others
Life balance
Life is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not, either because such functions have ceased , or else because they lack such functions and are classified as inanimate.Biology is the science concerned with the study of life.
Health
Health is the level of functional or metabolic efficiency of a living organism. In humans, it is the general condition of a person's mind and body, usually meaning to be free from illness, injury or pain]] (as in "good health" or "healthy"). The World Health Organization (WHO) defined health in its broader sense in 1946 as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity."Although this definition has been subject to controversy, in particular as lacking operational value and because of the problem created by use of the word "complete," it remains the most enduring. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction. Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health.
Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term "healthy" is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities,healthy cities or healthy environments. In addition to health care interventions and a person's surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic and social conditions; these are referred to as "determinants of health."
Photograph
A photograph or photo is an image created by light falling on a light-sensitive surface, usuallyphotographic film or an electronic image such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light", and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light"
Mona Lisa. The arts
The arts are a vast subdivision of culture, composed of many creative endeavors and disciplines. It is a broader term than "art", which as a description of a field usually means only the visual arts. The artsencompass the visual arts, the literary arts and the performing arts – music, theatre, dance and film, among others. This list is by no means comprehensive, but only meant to introduce the concept of the arts. For all intents and purposes, the history of the arts begins with the history of art. The arts might have origins in early human evolutionary prehistory. According to a recent suggestion, several forms of audio and visual arts (rhythmic singing and drumming on external objects, dancing, body and face painting) were developed very early in hominid evolution by the forces of natural selection in order to reach an altered state of consciousness. In this state, which Jordania calls battle trance, hominids and early human were losing their individuality, and were acquiring a new collective identity, where they were not feeling fear or pain, and were religiously dedicated to the group interests, in total disregards of their individual safety and life. This state was needed to defend early hominids from predators, and also to help to obtain food by aggressive scavenging. Ritualistic actions involving heavy rhythmic music, rhythmic drill, coupled sometimes with dance and body painting had been universally used in traditional cultures before the hunting or military sessions in order to put them in a specific altered state of consciousness and raise themorale of participants.
