Professional Challenge-Contemporary Issues and Policies - Assignment Example In other words, the private health agencies work with the profit motive where as the public health agencies aim for meeting the social obligations. Hence, any change in the health care policy affects significantly the efficiency of public health organization which in turn would influence the health care of the people. In the present paper, an attempt has been made to evaluate the impact of current health care issues and policies on the performance of public health care organization i.e. Department of Veteran Affairs (VA), United States of America. VA meets the social obligations by providing a wide range of benefits including, education and training, disability, vocational rehabilitation and employment, dependant and survivor benefits, burial benefits, medical treatment and life insurance. At the same time, VA provides benefits only to some selected and defined sections of the people like veteran, Veterans dependent, surviving spouse, child or parent of a deceased Veteran and uniformed service members. The national health care policy has always been designed keeping the overall welfare of the all the sections of the society in to consideration. For example, a joint VA and Department of Defense program was initiated which provides service members the opportunity to file claims for disability compensation up to 180 days prior to retirement from active duty or full time National Guard or Reserve duty which is very useful for the veterans under emergency circumstances. The national health care policy also facilitated the operatio n of ambulatory care & community based The economic burden of implementing new health care policies is the main factor that decides the success of the organization like VA. Day by day the needs of the patients have been growing necessitating higher number of out door units and ambulance services incurring additional costs. The national health care policy of USA has been ensuring that the

History and Development of Air-conditioning Research Paper

History and Development of Air-conditioning - Research Paper Example A close ancestor to the modern air conditioner units made in 1902, by an American engineer by the name of Willis Carrier. The machine at that time called "Apparatus for Treating Air" and built for the Sackett-Wilhelms Lithographing and Publishing Co. in Brooklyn, New York. Chilled coils used in machines to reduce air and lower humidity to 55%. Although the apparatus made with enough precision that the humidity level desired was adjustable. ("History of Air Conditioning") The article explains how air conditioners started becoming a commercial product as it became increasingly in use for industrial purposes. The real breakthrough achieved when Carrier had the benign dielene together with a central compressor replacing the ammonia thus reducing the size of the unit. Willis Carrier's invention came late in the 1900s, but before that, several attempts to air conditioning existed. In 180 AD, Ding Huan discovered the first ventilation system that was fan powered. The fan passed air from cold water and the air then spread in the house manually (Paventi). Later fountain water used to power the engine of the fan, thus reducing manual labor. Apart from the cooling effect of the water, the air became humid too (Paventi). In 1820 Michael Faraday, a British scientist, made a compressor that used ammonia (Paventi). Exhaustion of the toxic ammonia fumes became difficult and thus the cooling effect was unsafe. However, up to date his compressing technology is still in use.
