Ophthalmologist
Ophthalmology ( ) is a surgery, surgical subspecialty within medicine that deals with the diagnosis and treatment of eye disorders. An ophthalmologist is a physician who undergoes subspecialty training in medical and surgical eye care. Following a medical degree, a doctor specialising in ophthalmology must pursue additional postgraduate residency (medicine), residency training specific to that field. This may include a one-year integrated internship that involves more general medical training in other fields such as internal medicine or general surgery. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology. Ophthalmologists prescribe medications to treat eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists provide both primary and specialty eye care - medical and surgical. Most ophthalmologists participate in academic research on eye diseases at some point in their training an ...

Canton Christian College
Lingnan University () in Guangzhou (Canton), China, was a private university established by a group of American missionaries in 1888. At its founding it was named Canton Christian College (). When the Communist government reorganized China's higher education in the Soviet model in 1952, Lingnan University's engineering departments were incorporated into the newly established South China Institute of Technology (now South China University of Technology), and the rest of the school was incorporated into Sun Yat-sen University. Lingnan College was reestablished in 1988 within Sun Yat-sen University. Some members of the university moved to Hong Kong and founded the Lingnan School in Wan Chai in 1967, which was relocated to Tuen Mun in the mid-1990s and renamed Lingnan University in 1999. History The university was originally founded in 1888 by Andrew Happer at the request of the American Presbyterian Mission in Canton with the goal of providing a non-denominational Christian edu ...

Stereoscopic Acuity
Stereoscopic acuity, also stereoacuity, is the smallest detectable depth difference that can be seen in binocular vision. Specification and measurement Stereoacuity is most simply explained by considering one of its earliest test, a two-peg device, named Howard-Dolman test after its inventors: The observer is shown a black peg at a distance of 6m (=20 feet). A second peg, below it, can be moved back and forth until it is just detectably nearer than the fixed one. Stereoacuity is defined as the minimum angle detectable, calculated as the difference between the angles subtended by both positions, A and B. Stereoacuity is possible due to binocular disparity, i.e., the difference in their binocular parallax. Taking into account that a small angle expressed in radians can be approximated by its tangent, the formula to calculate stereoacuity ''dγ'' is this: :d\gamma = c\,a\,dz/(z\,(z - dz)) where ''a'' is the interocular separation of the observer, ''z'' the distance of the fixed peg ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pu Yi
Aisin-Gioro Puyi (; 7 February 1906 – 17 October 1967), courtesy name Yaozhi (曜之), was the last emperor of China as the eleventh and final Qing dynasty monarch. He became emperor at the age of two in 1908, but was forced to abdicate on 12 February 1912 during the Xinhai Revolution. His era name as Qing emperor, Xuantong (Hsuan-tung, 宣統), means "proclamation of unity". He was later installed as the Emperor Kangde (康德) of the Japanese puppet state of Manchukuo during World War II. He was briefly restored to the throne as Qing emperor by the loyalist General Zhang Xun from 1 July to 12 July 1917. He was first wed to Empress Wanrong in 1922 in an arranged marriage. In 1924, he was expelled from the palace and found refuge in Tianjin, where he began to court both the warlords fighting for hegemony over China and the Japanese who had long desired control of China. In 1932, after the Japanese invasion of Manchuria, the puppet state of Manchukuo was established by Japan, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviation Medicine
Aviation medicine, also called flight medicine or aerospace medicine, is a preventive or occupational medicine in which the patients/subjects are pilots, aircrews, or astronauts. The specialty strives to treat or prevent conditions to which aircrews are particularly susceptible, applies medical knowledge to the human factors in aviation and is thus a critical component of aviation safety. A military practitioner of aviation medicine may be called a flight surgeon and a civilian practitioner is an aviation medical examiner. One of the biggest differences between the military and civilian flight doctors is the military flight surgeon's requirement to log flight hours. Overview Broadly defined, this subdiscipline endeavors to discover and prevent various adverse physiological responses to hostile biologic and physical stresses encountered in the aerospace environment. Problems range from life support measures for astronauts to recognizing an ear block in an infant traveling on an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trachoma
Trachoma is an infectious disease caused by bacterium ''Chlamydia trachomatis''. The infection causes a roughening of the inner surface of the eyelids. This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. The bacteria that cause the disease can be spread by both direct and indirect contact with an affected person's eyes or nose. Indirect contact includes through clothing or flies that have come into contact with an affected person's eyes or nose. Children spread the disease more often than adults. Poor sanitation, crowded living conditions, and not enough clean water and toilets also increase spread. Efforts to prevent the disease include improving access to clean water and treatment with antibiotics to decrease the number of people infected with the bacterium. This may include treating, all ...
