Upgrading the Network Configuration PAGE 1 PAGE 1Daryl Christopher YostIT388-01: Routing and Switching IInstructor Robert Knox JrOur company needs to think about upgrading their network. As for the network, we want to propose a full upgrade that means, network operating systems, software and hardware. Our proposal includes the development of a LAN able to meet the requirements of your company's software. The computer network components for the proposed upgrade will include the use of a server, a switch, patch panel, and a router for the office. The selected NOS (Network Operating System) is Windows 2003 Server or Windows Server 2007, preferably the latter. These operating systems provide great conveniences to the installation, configuration, and maintenance of the network. Windows 2003 Server provides the enhanced DHCP, DNS and WINS features allow a network administrator to expediently manage all clients on the network. The data communication media for the networks is UTP CAT5.Windows Server 2003 Standard Edition cov er boxThis cabling follows the Ethernet standards for TCP/IP and ensures decreased propagation and noise.The network portion of the proposal will consist of firewalls, routers, switches, load balancers, and content engines (used here as reverse-caching appliances). This combination of equipment will provide us with security, performance, and scalability. Our database server will sit inside our internal network to protect our data from unauthorized access. Our web servers will sit in our DMZ and will access the database server through an internal firewall. Access to the web servers from the internet will come through an outside or shield router and an external firewall, which is attached to a T1 data line provided by out Internet Service Provider. Directly behind the external firewall in the DMZ, we will place a load balancer. This device will do server load balancing (SLB) for the web servers. The content engines will be...

Free Essays on The History Of Ska Music

The music genre ska originated in the island of Jamaica and caused a social movement like that of many other types of music. Ska came from the music genre of mento. It was born out of the fusion of combining musical elements of both mento and jazz. The combined musical elements that produced a new style initially were called â€Å"Shuffle,† in Britain. Recording studios were always on the look out for the next new sound. With the popularity of American artists, Jamaican performers incorporated blues chord progressions and boogie bass lines with mento guitar rhythm. An increase of emphasis was placed primarily on the offbeat rhythm of mento, which eventually became shorter and more detached. Percussion came in on the second and fourth beats, which carried the blues and swing beat of American music, while the guitar emphasized the up of the second, third, and fourth beat. This distinction of syncopated rhythm sounded was referred as the new style of music known as ska. During the 1920's-1930's, the local band scene in Jamaica was that of mento music. Mento was a type of music commonly known as rural music because of the fact that the bands were local bands. Typical mento bands played at weddings, local dances, fairs, and concerts. Some of the local bands were even employed as bands for house parties. After awhile, the popularity of mento music experienced a steady decline. It was then during the late 1950's that the slow transition into ska music took effect. Bands that traveled on the road got more daring in their application of music, which was referred to as the Jamaican mobile disco. Mobile disco DJs traveled from town to town and their success was based upon the sound that came from America. The American sound consisted of music from performers such as Fats Domino, Duke Ellington, Count Basie, Louie Jordan, and Ray Charles. Two men performed a critical role in the development of the sound systems era in Jamaica....

North Korea Essay Example | Topics and Well Written Essays - 4500 words

North Korea - Essay Example After the collapse of the Goryeo rule in Korea, this led to the rise of the Josen kingdom in honour of the Gojosen one. Towards the end of the sixteenth century, Japanese pirates attempted to attack Korea, however the invasions were repulsed between 1592 and 1598, in the early seventeenth century, Korea became involved in wars with the Manchus kingdom. The rule by Josen closed Korea to trade in the 17th to 19th century with it only being open to China, however at one time an American merchant ship, which was armed, tried to open Korea to external trade in the 19th century was stranded in a river near Pyongyang (Miller, 2004 p102). After the crewmembers were ordered to leave, they killed several Korean nationals that led to the ship being torched by fire ships from Korea but by mid 19th century, Pyongyang had a cautious and a slow approach towards opening its boarders towards the west. Due to the Sino japans war that happened from 1894 to 1895, the treaty of Shimonoseki was signed whi ch led to the end of Josean Empire relying on China. The name Josean Empire was changed to Korean empire, which was highly influenced by Russia, this however ended after the Russo Japan war between 1904 and 1905 when the Korean empire became a protectorate of Japan. When Japan annexed Korea, they imposed a military rule and attempted to stem Korean way of life and traditions, the wealth of the Korean empire was used to profit the people of Japan. This led to formation of pro- rebellion movements from Koreans towards the Japanese rule, in 1919 pro liberations, rallies took place countrywide and about 7000 people were killed. This fuelled more protests against the Japanese that led to the Japanese strengthening their military rule and banning anything related to Korea including forcing the Koreans to change their names to Japanese names, changing the curriculum in schools to reflect that of Japan and the Japanese culture, the Korean language was also banned. With the surrender of the Japanese after the world war ii, the Korean empire was divided into two along the 38th parallel where the soviet union occupied the north and America the south in an agreement that had been signed before, Russia chose Kim II Yung to lead the provisional peoples’ committee for North Korea in 1946. Kim II Yung introduced radical reforms in North Korea that ranged from land reforms to nationalising all key industries in the country. Talks on unifying north and South Korea were held in Moscow and Seoul; however, they did not bear any fruits due to the politics of the cold war that was happening at the same time. Soviet Union military withdrew from North Korea, the American counterparts withdrew from South Korea a year later, this made South Korea weaker and the government of Kim II Yung began exploring the possibilities of invading South Korea. Soviet Union under the leadership of Joseph Stalin rejected the war proposals that North Korea presented to him, however, with the win of Mao Zedong in China and the indication that he was willing to support the invasion, the Soviet Union approved the invasion in 1950. With Joseph Stalin having approved the war, the north that had a stronger army than the south decide to invade the south, there were battles at the 38th parallel that turned bloody in the Ongjin region, however none of the armies closed the line to the rival’

Anesthetic Management of the Patient with Aortic Stenosis Essay

Anesthetic Management of the Patient with Aortic Stenosis - Essay Example Surgery is indicated in many of the cases in order to repair or replace the diseased valve. Therefore, it is the purpose of this paper to investigate the current anesthetic management of this disease, from preoperative to postoperative care. This paper will describe the basic anatomy and physiology of the heart, in particular, the aortic valve. The pathophysiological changes in the aortic valve and the heart will also be discussed. The heart is a hollow muscular organ that is somewhat pyramid-shaped and lies within the inferior mediastinum (3). It is covered by a fibroserous sac called the pericardium, within which pericardial fluid fills the space between the serous and fibrous layers. The pericardial fluid acts as a lubricant to prevent friction during the contraction of the heart. The pericardium is not very distensible, and therefore it strongly resists a large, rapid increase in cardiac size. Hence, the pericardium also prevents sudden overdistention of the chambers of the heart (4). The heart is divided by a vertical septa into four chambers: the right and left atria, which occupy the upper chambers and the right and left ventricles, which occupy the lower chambers. ... Although most myocardial cells are able to perform both these functions, the vast majority is predominantly contractile cells (myocytes) and a small number are specifically designed as electrical cells. The latter, collectively known as the conducting system of the heart, are not nervous tissue but modified myocytes lacking in myofibril components. They have the ability to generate electrical impulses which are then conducted to the myocytes, leading to contraction by a process known as excitation-contraction coupling (5). In order to produce a synchronized contraction, there must be a normal spread of electrical activity within the heart. Depolarization is initiated in the sinoatrial node (SA) node hence it is known as the pacemaker of the heart. It sets the contractions of the heart at a rate of 60-100 beats per minute. From the SA node, the electrical impulse travels to the atrioventricular (AV) node and then propagates through the Bundle of His. From the top of the septum, the wa ve of depolarization spreads in the rapidly conducting Purkinje fibers to all parts of the ventricles (6). Between the atria, ventricles and great blood vessels arising from the heart (aorta and pulmonary artery) are valves, which are made up of cusps or leaflets to prevent backflow of blood, ensuring a one-way conduit of blood through the chambers and to the pulmonary and systemic circulation. There are four valves: two semilunar valves (aortic and pulmonary valves) and two atrioventricular valves (tricuspid and mitral valves). All of these valves have 3 cusps except the mitral valve which has two cusps. Unoxygenated blood from the superior and inferior vena cava and coronary

Classical Period and Romantic Period Research Paper

Classical Period and Romantic Period - Research Paper Example When we talk about classical music it is important to know that the term is applicable to music that was composed in a particular style from the 1740s to 1820. The composition of music during these years comprised of a distinct sense of proportion. Initially it was somewhat difficult for listeners to derive pleasure and enjoyment from, however after a certain time the music began to dominate their music preferences. Initially the perception modern listeners have of the classical era is that it was either too serious or plain music; however to the listeners in that era, the music was unique and very different from that of the Baroque era. The key distinction between classical era and that of the Baroque era was that the classical music had more variety when it came to divergent rhythms throughout a piece. Melodies which were introduced in the classical era were a lot more balanced, easier to sing and to remember. It was in this era that numerous nursery songs were written. It was in t he classical era that the social function of music started to evolve from that of its prior aristocratic and religious affiliations towards the public and secular sphere with its middle class connections. The gradual increase in public concerts, the growth of commercial opera houses, the increase of publishing of music, and the increase in the number of musical pieces that were composed as well as played were all implications of the change in musical times. Form was of critical importance to the composers of the classical era, and this period had a lasting effect as far as form is concerned, especially when it came to the various instrumental music forms. Previously composers had already begun to pay special attention to the various musical instruments and their capabilities. Hence the move to writing not just solo music for one specific instrument, but focusing on music which had mixed ensembles with a variety of instruments. The modern orchestra was of key importance here. It was in the classical era that the common instruments like the toccata, concerto grosso, and fugue became replaced by forms which had matured as a result of the classical period. This is where the roots of the sonata, concerto and symphony can be traced. Even though each of these forms had significant precursors prior to the classical era, but it is this version of the form that came to become the most influential through the course of the other following eras, the romantic and modern era, and even today it is still highly recognized by a multitude of art music audience and performers (Jones, 2006). Among the many kinds of music of this period, the classical era is well known for symphonies, which is a type of a large orchestral ensemble. These pieces of symphonies primarily had three movements; the first of these was the sonata, followed by the minuet, and the finale. Taking inspirations from earlier composers, Haydn and Mozart took symphonies to their peak in the late 18th century. Whi le Haydn concentrated on achieving rhythmic excellence and the composition of theme based music Mozart contributed to the symphonies by a contrast of memorable lyric themes which made use of a full sounding orchestral settings (Roger, 2008). To cater to the middle-class, classic composers came up with a ton on new chamber music which made use of a magnitude of combinations. The piano sonata became one of the important forms of chamber music. This was mainly after the refinement it received at the hands of composers like Haydn, Mozart and Beethoven. The string quartet played an

The home was formed in 1812 and was followed by the formation of Soldiers Home in 1853 and St. Elizabeth’s Hospital in 1855. Congress shaped the National Home for Disabled Volunteer Soldiers in 1865 in answer to the towering number of Civil War casualties. These homes were at first intended to be room and board for disabled veterans. Though, by the late 1920’s, the homes were giving a level of care similar to hospital care. Beginning in the mid-1990s VHA undergo what the agency characterizes as a major alteration aimed at improving the excellence and effectiveness of care it provides to its patients. That conversion included eliminating underutilized inpatient beds and amenities, increasing outpatient clinics, and reorganization eligibility rules. A main focus of the conversion was the tracking of a number of routine indicators—counting quality-of-care procedures—and holding senior managers responsible for improvements in those events. In the July 18, 2005 matter of US News and World Report, Veterans Administration hospital care is hyped as over and over again as the best around. The high ranking to the conversion of the VA health care classification over the precedent decade. Starting in the l990s under the guidance of Dr. Kenneth Kizer, the Veterans Health Administration organized a presentation and answerability system that was joined openly to the value of patient care and result. Patient protection and a new culture of safety that heartens coverage and assessment of errors plus close calls, instead of the corrective emergence of the past, carry on to be an aspect in Veterans Administration’s success (Allison Percy, 2009 ). In adding up, computerized patient report, clinical reminders that endorse guideline suggested care, a bar coding system for further precise drug
