Information: - Diagnosis is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions. - A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the causal study of etiology. Disease is often construed as a medical condition associated with specific symptoms and signs. It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity. - A variant of eccrine spiradenoma which can be multiple on the scalp and can coalesce to form a 'Turban' tumour. In pathology, a cylindroma is a tumour with nests of cells that resemble a cylinder in cross section. - In dermatologic pathology , a dermal cylindroma , also dermal eccrine cylindroma ) and ( less specifically ) cylindroma , is a benign adnexal tumor , which occurs on the scalp and forehead . Multiple cylindromas may grow together in a '' hat - like '' configuration , the so - called '' turban tumor . '' Cylindromas are uncommon dysplasias of skin appendages . - Pathology (from the Greek roots of "pathos", meaning "experience" or "suffering", and "-logia", "study of") is a significant component of the causal study of disease and a major field in modern medicine and diagnosis. - Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Information: - Telemark skiing is a skiing technique that combines elements of Alpine and Nordic skiing. Telemark skiing is named after the Telemark region of Norway, where the discipline originated. Sondre Norheim is often credited for first demonstrating the turn in ski races, which included cross country, slalom and jumping, in Norway around 1868. Sondre Norheim also experimented with ski and binding design, introducing side cuts to skis and heel bindings (like a cable). - International Ski Federation (FIS; short for Federation Internationale de Ski) is the world's highest governing body for international winter sports. Founded in 1924, it is responsible for the Olympic disciplines of Alpine skiing, cross-country skiing, ski jumping, Nordic combined, freestyle skiing and snowboarding. The FIS is also responsible for setting the international competition rules. The organization now has a membership of 118 national ski associations and is based in Oberhofen am Thunersee, Switzerland. - Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski Federation (FIS). - Nordic skiing pertains to skiing disciplines that use equipment where the toe of the ski boot is fixed to the binding in a manner that allows the heel to rise off the ski, unlike Alpine skiing, where the boot is attached to the ski from toe to heel. Recreational disciplines include cross-country skiing and Telemark skiing. - A ski is a narrow strip of semi-rigid material worn underfoot to glide over snow. Substantially longer than wide and characteristically employed in pairs, skis are attached to ski boots with ski bindings, with either a free, lockable, or partially secured heel. For climbing slopes, ski skins (originally made of seal fur, but now made of synthetic materials) can be attached at the base of the ski. - A winter sport or winter activity is a recreational activity or sport which is played during cold weather months. Most such sports are variations of skiing, ice skating and sledding. Traditionally such sports were only played in cold areas during winter, but artificial snow and artificial ice allow more flexibility. Artificial ice can be used to provide ice rinks for ice skating, ice hockey and bandy in a milder climate. - The International Olympic Committee (IOC; French: Comite international olympique, CIO) is the supreme authority of the worldwide Olympic movement. It is an international, non-profit, non-governmental organization based in Lausanne, Switzerland. Its mission is enshrined in the Olympic Charter: to support the development of competitive sport by ethical and environmentally sustainable means. - Sondre Norheim , born Sondre Auverson , ( June 10 , 1825 -- March 9 , 1897 ) was a Norwegian skier and pioneer of modern skiing .
