Blood Pressure And Pulse Lab Physical Education Essay

Blood Pressure And Pulse Lab Physical Education Essay The purpose of the blood pressure and pulse lab was to test many variables which could have an effect on blood pressure and pulse. The variable tested in this lab was the, Effects of Changes in Posture, the Effects of Exercise, and the Effects of Cognitive Stress on Mean Arterial Pressure and Heart Rate. Background: Blood is an essential factor for all living organisms. Blood is an important fluid within our bodies which delivers oxygen, nutrients and essential substances, to cells throughout the body. Blood also has the function of transporting various wastes materials / products, such as carbon dioxide, from various body cells through the respiratory and excretory organs. The activities performed in the blood pressure and pulse lab examined the rate at which blood flows throughout the body, and which factors would either increase or decrease the blood pressure, being the pressure of the blood within the circulatory system, and pulse pressure. Blood flow and blood pressure is determined by two distinct factors. These factors are the force needed to push the blood through the blood vessel and the amount of resistance of blood flow through the blood vessel. The average normal blood pressure in a healthy individual should be around 120/80 BP, but it is stressed that the blood pressure should remai n a little lower than this pressure. The sympathetic and parasympathetic nervous system plays an important role in blood pressure and heart rate. The sympathetic nervous system through the Cardio acceleratory center increases heart rate in fight or flight situations. While the parasympathetic nervous system uses the cardio inhibitory center to decrease the heart rate. The mechanical events of the cardiac cycle are the sequences of events which take place in order for the heart to work properly. In the cardiac cycle there are two distinct phases. These two phases are the diastole phase and the systole phase. In the medical field the diastolic pressure and the systolic pressure are measured with the use of a stethoscope and Sphygmomanometer. The measure of pulse pressure refers to the difference between the systolic number (Top) and the diastolic number (Bottom). The normal blood pressure of a healthy individual is 120/80 BP; in this instance, the pulse pressure would equal 40mmHg (120 80 = 40mmHg). Blood pressure is constantly fluctuating; because of this doctors need to take an average blood pressure to adequately check for any complications in their parents. The average blood pressure is called the mean arterial pressure (MAP). To begin to calculated the mean arterial pressure one must first start by calculating the pulse pressure (PP). The Puls e pressure can be calculated by taking the difference between the systolic pressure (SP) and the diastolic pressure (DP); (PP = SP DP).Using the Pulse pressure the mean arterial pressure can be calculated. The mean arterial pressure is equal to a third of the pulse pressure plus the diastolic pressure (MAP = DP + (PP*1/3) ). The basic mechanical events of the cardiac cycle can be deduced into four phases. Phase one in the cardiac cycle is referred to as the First Diastole Phase. During the first diastole phase, the atria and ventricles within the heart are fully relaxed, as the Atrioventricular valves remain open. This allows De-oxygenated blood to flow to the right atrium, from both the superior and inferior vena cavae. The rate in which blood flows back into the heart is given the term Venous Return (De-oxygenated blood). The muscles incorporated in exercise require a lot of oxygen in order to perform their function, as a result there would be an increase in venous return. Blood within the right atrium is emptied into the right ventricle though the Atrioventricular or Tricuspid valve. At the end of diastole (the loading or filling phase), the amount of blood accumulated in the right or left is referred to as the end-diastolic volume (EDV). The second phase of the cardiac cycle is referred to as the first systolic phase. During this phase the right ventricle receives incoming electrical signals from the purkinje fibers, which are the fibered branches which extend from the Atrioventricular bundle, in the intraventricular sulcus of the heart, and are dispersed from the apex of the heart. The purkinje fibers signal the ventricles to contract, which closes the Atrioventricular valves and forces the semilunar valves to open, pushing de-oxygenated blood into the pulmonary arteries. The pulmonary arteries function is to prevent the flow of blood back into the right ventricle. All of the blood is never fully ejected from the ventricles after systole. The amount of blood which remains in the ventricle at the end systole is known as end-systolic volume (ESV). The end-diastolic volume and the end-systolic help to calculate the stroke volume (SV) which is the volume of blood ejected from one ventricle during each beat. The stroke v olume can be calculated by taking the difference between end-diastolic volume and end-systolic volume, (SV = EDV ESV). The stroke volume can also be used to calculate the cardiac output, or the rate at which blood is ejected from the heart, (CO = HR x SV). In the second diastolic phase, the semilunar valves are closed and the Atrioventricular valves are opened, as a result oxygenated blood within the pulmonary veins and beings to fill within the left atrium. At the same time, blood from both vena cavae fills within the right atrium. The mitral valve closes preventing any oxygenated blood from flowing back within the left atrium. In the second systolic phase, Atrioventricular valves close and semilunar valves open. Similar to the first systolic phase, Purkinje fibers send messages to the ventricles signaling them to contract, in which oxygenated blood is pumped into the aorta. The aortic semilunar valve prevents any oxygenated blood from pumping directly back into the left ventricle. Hypothesis: Posture Changes Reclining for 3 minutes It is expected that arterial pressure and pulse rate would most likely decrease; when someone is resting the body is controlled by the parasympathetic system which uses the cardio inhibitory center to decrease heart rate. Standing up quickly after reclining for 3 minutes It is expected that arterial pressure and pulse rate will increase, when the subject is in the standing position versus when they are laying down their blood has to overcome gravity and the heart has to work harder to produce the force necessary to push blood to the upper limbs. Standing at attention for 3 minutes It is expected that arterial pressure will decrease compare to standing up quickly after reclining for 3 minutes, because 3 minutes is a long enough period for the body to adjust to the effects of gravity and to assess the force needed to pump blood to the upper extremities. It is hypothesized that the standing at attention for 3 minutes data will be an intermediate between the reclining test and the standing up quickly after reclining test. Exercise Immediately after exercising it is expected that arterial pressure and pulse pressure will increase, because muscles involved in the exercise demand more oxygen which will increase the amount of venous return and increase the heart rate and pulse pressure. One, Two, and Three, minutes post exercise It is expected that arterial and pulse pressure will decrease compared to immediate testing after exercise. As the individual begins to rest after strenuous exercise the body begins to incorporate the parasympathetic nervous system and through the cardio inhibitor center, it begins to decrease the heart rate. Cognitive Stress It is expected that cognitive stress will increase the blood pressure slightly, because stress is believed to trigger the sympathetic nervous to increase the heart rate. Procedure For Procedures, Refer to Lab 6, Activity 2, in the Anatomy and Physiology Lab Manual Data Results: Lab Activities Data Tables Proper use of the Sphygmomanometer: Subject: Brianna Burton Systolic Pressure Diastolic Pressure Pulse Pressure MAP Trial 1 110mmHg 70mmHg 80mmHg 83.33 mmHg We were told by the instructor there was no need to perform a trial 2 Effect of Postural Changes Subject: Same as above Blood Pressure Pulse Rate MAP Sitting Quietly (Baseline) 110/70 mmHg 80 BPM 83.33 mmHg Reclining (After 2-3 minutes) 110/70 mmHg 76 BPM 83.33 mmHg Immediately Upon Standing 118/78 mmHg 92 BPM 91.33 mmHg After Standing for 3 Minutes 112/72 mmHg 85 BPM 85.33 mmHg Exercise Subject: (Well-Conditioned) Aaron Banks Fitness Index: 50 Subject: (Poorly-Conditioned) Justin Kim Fitness Index: 44 Baseline Immediately 1 Minute 2 Minutes 3 Minutes 4 minutes 5 Minutes Well-Conditioned Subject BP: 130/80 mmHg BP: 132/80 mmHg BP: 128/70 mmHg BP: 120/78 mmHg BP: 110/68 mmHg BP: 110/72 mmHg BP:108/72 mmHg HR: 90 BPM HR: 101 BPM HR: 103 BPM HR: 100 BPM HR: 98 BPM HR: 98 BPM HR: 87 BPM MAP: 96.67 mmHg MAP: 97.33 mmHg MAP: 89.33 mmHg MAP: 92 mmHg MAP:86.67 mmHg MAP: 84 mmHg MAP: 84 mmHg Poorly-Conditioned Subject BP: 122/98 mmHg BP: 128/90 mmHg BP: 138/86 mmHg BP: 120/82 mmHg BP: 122/90 mmHg BP: 122/90 mmHg BP:118/96 mmHg HR: 82 BPM HR: 120 BPM HR: 119 BPM HR: 111 BPM HR: 110 BPM HR: 110 BPM HR: 108 BPM MAP: 106 mmHg MAP: 102.67 mmHg MAP: 103.33 mmHg MAP: 94.67 mmHg MAP: 106.67 mmHg MAP: 100.67 mmHg MAP: 103.33 mmHg Cognitive Stressor Subject: Nika Condition Max HR Min HR Mean HR Systolic BP Diastolic BP Pulse Pressure MAP Baseline 1 100 BPM 82 BPM 89 BPM 134 mmHg 91 mmHg 43 mmHg 105.3 mmHg Spell Forward 96 BPM 83 BPM 91 BPM 108 mmHg 88 mmHg 20 mmHg 94.7 mmHg Spell Back 112 BPM 84 BPM 92 BPM 111 mmHg 89 mmHg 29 mmHg 96.3 mmHg Number of misspelled words forward = 1 Number of misspelled words backward = 3 Discussion: The purpose of the blood pressure and pulse lab was to test many variables which could have an effect on blood pressure and pulse. The variables tested in this lab were the, Effects of Changes in Posture, the Effects of Exercise, and the Effects of Cognitive Stress on Mean Arterial Pressure and Heart Rate. In activities the variable being tested is the Effects of Changes in Posture. For the baseline the subject, in this case Brianna, sat quietly as her baseline blood pressure, pulse rate, was tested, and her mean arterial pressure (MAP) was calculated. The results for Briannas blood pressure was 110/70 mmHg, which is about the average blood pressure (120/70 mmHg) in a healthy individual. Her Pulse pressure was 80 beats per minute (BPM). Given these values her baseline MAP, was calculated to be 83.33 mmHg (MAP = 70 + ((110 70))*1/3) ). In the next test, the effect of reclining for 2-3 minutes was tested. In this test, after reclining for 2-3 minutes, her blood pressure, and MAP remained the same as the Baseline test. It was observed that her pulse rate did in fact decrease: (80 > 76 BPM), though it is not known if this decrease in the pulse rate is significant enough. In the hypothesis above it was expected that arterial pressure and pulse rate would most likely decrease when someone i s resting because parasympathetic nervous system would begin to signal the body to relax affecting the cardiac centers (CAC deactivated CIC activated). The activation of the cardio inhibitory center decreases the heart rate and pulse pressure. For the next test the Effect of standing quickly after 3 minutes of reclining was tested. Immediately after standing up, her Blood pressure, Pulse rate and MAP was determined. Her blood pressure was 118/78 mmHg, her Pulse Rate was 92 BPM and her MAP was 91.33 mmHg. The MAP was calculated by using the formula: (91.33 mmHg = 78 + ((118-78))*1/3)). During this test Briannas Blood pressure, Pulse Rate and MAP significantly increased, ((BP: 110/70 >> 118/78 mmHg) (PR: 80 >> 92 BPM) (MAP: 83.33 >> 91.33 mmHg) as expected in the hypothesis. In the hypothesis it was expected that arterial pressure and pulse rate would increase, when the subject is in the standing position versus when they are lying down. When Brianna quickly stood up her heart had to overcome the effects of gravity; the heart has to work harder to produce the force needed to effectively push blood to the upper limbs and the head. Also immediately standing activates the sympathetic nervous system, which activates the CAC incr easing heart rate. This hypothesis is accepted, based on her data the blood pressure, pulse rate and MAP did in fact increase when she stood up. Next we tested the Effects after standing for 3 minutes. After standing for 3 minutes Briannas blood pressure was 112/72 mmHg and her pulse rate was 85 BPM. Given these values her MAP for this test was calculated to be 85.33 mmHg (MAP = 72 + (112-72)*1/3). In the hypothesis it is expected that the arterial pressure would have decreased compared to the standing up quickly after reclining for 3 minutes test. It was hypothesized that arterial pressure would decrease because 3 minutes is a long enough period from the body to properly adjust to the effects of gravity and to assess the force needed to pump blood to the upper extremities. As stated in the hypothesis the blood pressure, pulse rate and MAP did in fact decrease based on the standing for 3 minutes test, because of this, the hypothesis can be accepted (BP: 110/70 >> 112/72 mmHg) (PR: 80 >> 85)) (MAP: 83.33 mmHg >> 85.33) In the next test, we tested the effects of exercise on the Body, comparing a well-conditioned person and a poor-conditioned person. For the first test a well-conditioned person was chosen. The baseline BP for this individual was around 132/80 mmHg. Immediately after exercise the blood pressure was 132/80 mmHg. This shows that there was an increase of blood pressure dependent on the effects of exercise. In the hypothesis it is expected that arterial pressure and pulse pressure will, increase, because muscles involved in the exercise also increase the venous return which will increase heart rate. For this test as hypothesized the Heart rate also increased (90 >> 101 BPM). After 5 minutes of resting the blood pressure and Heart of the subject decreased lower than the baseline, indicating some level of human error in reading the equipment effectively. Despite this, it is found that the blood pressure and pulse rate at 5 minutes was significantly lower from the baseline in the well-condit ioned person vs. the poor conditioned person. In the poor conditioned person. Their baseline blood pressure was 122/98 mmHg and after exercising for 5 minutes it was 128/90 mmHg. After 5 minutes the poor conditioned persons blood pressure was 118/96 mmHg. Again in this experiment its hard to compare the two subjects because there seems to be some human errors in effectively checking the blood pressure since it is lower than the baseline. After 5 minutes the well-conditioned persons systolic pressure dropped from 128>>108 SP despite the diastolic pressure increasing from 70 >> 72 mmHg DP. The fitness index to the well-conditioned person was 50 and 44 for the poor conditioned person. Based on the fitness index both subjects display the poorest physical conditioning possible. For the final test the effects of cognitive stress was tested. Based on this experiments results it is difficult to determine whether or not cognitive stress had any effect on the blood pressure. It was hypothesized that cognitive stress would increase heart rate because stress activates the sympathetic nervous system, which increases the heart rate. There seems to be no correlation between cognitive stress and heart rate, so the hypothesis is rejected.

Giuliani :: essays research papers

When Mayor Giuliani first began his campaign for mayor he placed a strong emphasis on quality of life, crime, business, and education. This strategy proved to be very successful and he was appointed as the 107th Mayor of New York. As Giuliani began his term began to follow through on his promises and made several changes in many of New York’s important bureaus ("Biography of Rudolph,† n.d.). The first task that Giuliani took was that of decreasing the amount of crime that was present in New York. He implemented new strategies that have since become models that many other large cities from around the world have followed. While Giuliani was mayor, overall crime was down 57%, and murder was decreased by 65%. With these statistics, New York was recognized by the FBI as the safest large city in the world for five continuous years ("Biography of Rudolph,† n.d.). Another area that Giuliani implemented change was in the area of welfare. At the beginning of his term as mayor, one out of seven New York residents was on welfare. Giuliani started a program which would bring work to these residents and help them to become able to support themselves financially. Through this program 640,000 people were able to get off welfare and stop relying on welfare money provided by the government ("Biography of Rudolph,† n.d.). The last area that Giuliani brought change to was the area of education. Giuliani felt that this was a very important and focused on increasing money for education and bringing up standards. He helped to bring the student-teacher ratio to the lowest it had been in many years and increased available money for education by four million dollars.

A Sense of Belonging Essay

â€Å"Ð  sense of belonging† is a book that nobody should miss! It provides students with the opportunity to examine different writing models and techniques while raising their awareness of different issues such as racial discrimination and racial abuse. Many of my friends found it interesting to read and could not stop reading the whole book although we were told to finish only four stories and only stopped flipping and reading till the last page! I personally find the book worth a read and would like to recommend it to all the secondary 3 and 4 students. Stories in the book include â€Å"a sense of belonging† and â€Å"The Test† which are about racial differences and a lady that was very mindful of her race. It does not merely elaborate on racial discrimination which can be very common but also tells us to be more sensitive towards other people and to be aware of our actions, as our words have the ability to hurt others. This is especially applicable to students of our age as we often meet friends of different races in school, and it reminds us that we should be considerate to others â€Å"The limits of trooghaft† highlights the plight of animals as humans are being treated the way we treat animals during the period of time we dominated the world. It serves as a reminder for us to put ourselves in others’ shoes and also consider the fact that animals have feelings and should not be abused like the way many are being treated now because animals have their own rights. This is a relatively important value in life that people need to constantly reinforce, so that we do not end up treating other people the way we do not want them to treat us. â€Å"a sound of thunder† talks about small mistakes leading to dire consequences and reminds us not to neglect the small details in life, because they can be important as well. After reading the book I personally found these four stories very inspiring and interesting. They allowed me to understand more about the common issues and problems faced, while learning moral values and reflecting on my daily life as we can easily relate to some of the stories in the book The important messages and lessons I learnt were invaluable to me and will accompany me for the rest of my life. Therefore I would strongly recommend this book to all upper secondary students as it can help them approach then own writing with more confidence and understanding, while teaching them life values at the same time.

The banking industry in the United Arab Emirates

The banking industry in the United Arab Emirates Background The banking industry in the United Arab Emirates is faced with fiancà © completion from public and private players. The United Arab Emirates has a well-developed banking sector and the economic strength of the country has created a business opportunities to foreign and local players.Advertising We will write a custom essay sample on The banking industry in the United Arab Emirates specifically for you for only $16.05 $11/page Learn More The economy has some of the world largest international banks like Barclays Bank, The International Bank for Trade Finance, Syria Gulf Bank and other small upcoming banks and microfinance (Syria Gulf Bank). This paper takes an analysis of Syria Gulf Bank; it will look into the company’s operating base and its competition. Which business do you think will be the biggest competitor in the United Arab Emirates, why? The main competitors that the bank is likely to face are conventional and Islamic multinationa l banks that have stated to venture in the United Arabs Emirates business. Among the banks, the bank that seems to have much power and can be said to be the greatest threat to Syria Gulf Bank is Barclay’s banks limited. The reason for singling out Barclays as the main competitor is its international operations and the services that it has embarked on in its branches. Barclays’ Bank is among the oldest banks in the world; it has grown with different economies and transformed with changes that are facing the sector; one way that the bank has used to integrate its business is the use of single fund transfer and access to ones account at any Barclays bank in the world. This means that a customer of the bank has the ability to make banking transaction in any country without having to undertake some interbank transfers; this rate of efficiency coupled with the banks international presence in different countries offers it a higher chance to convince customers that it is the b ank of choice. For example, a customer who is transating with the bank in the United Stattes of America receives a transfer by a customer at the United Arabs Emirates on the spot (Barclays Bank).Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More When Syria Gulf Bank is engaging in an international transfer, mostly in the countries that it has not established a branch, it has to do this using another holding bank. This takes time and is costly to the customer. Another area that Barclays bank has been able to stand strong is its financial base; the company has been in operation for a couple of years thus it has accumulated a financial base that it uses to expand its operations; the strong financial base assist the company tap new upcoming business opportunities leaving others banks with less financial base struggling. In the wake of global financial crisis, the company has been able t o use its financial base to acquire assets and make policies that strengthen their business approach. The most competitive parameter that Syria Gulf Bank has is its specialized services, the company has only few customers thus it can forge its services and products to meet the needs of the customer. This facilitates business since a customer does not need to queue for banking services. Again the technology adopted to handle the business of the company is high tech, the Automated Terror Machines and internet banking are highly efficient and not jammed as the case is with Barclays such services. The above moves by the company are likely to offer it a competitive edge than Barclays (Syria Gulf Bank). What is the difference between vision and mission in formulating business strategies; please provide relevant examples released by international companies When making operating strategies, managers are guided by the company’s, mission, vision, and corporate objectives; the business frameworks are provided by the shareholders or the entrepreneur who have the mind picture of what they want in their organization. When the mission, vision and objective are fulfilled, then management agency relationship or contracts are fulfilled. An effective mission, vision and objectives should be attainable and reflect the needs operation of a company.Advertising We will write a custom essay sample on The banking industry in the United Arab Emirates specifically for you for only $16.05 $11/page Learn More In the international business arenas, there are some countries that have fulfilled their visions and missions continuously; they include Toyota Motor Corporation and Emirates Airlines company in the United Arabs Emirates; this section of the paper defines the major difference between mission and vision, it will be suing examples of Toyota company and Emirates Airline company. Mission Mission defines the main business of the company and how it aims at fulfilling its business; it has the business objectives and goals of success that when fulfilled the company will have attained its business competitiveness. Toyota has a mission statement as, â€Å"To attract and attain customers with high-valued products and services and the most satisfying ownership experience in America†( Toyota Motor Corporation Corporate Website). The management either in Japan where the head quarters are, or in other branch are guided by the mission they want to attain. When one analyzes the mission statement, the company simply illustrates how it wants to add value in peoples life, through its innovative products. Emirates has the mission of â€Å"An exceptional journey from start to finish,† † (Emirates Airline Company Corporate Website); this means that the company is willing to offer high quality transport services to its customers all over the globe. The mission has been attained through massive inventive and innovative of models, and involvement in corporate social responsibilities. To attain the mission, the company needs to keep reminding its human capital and stakeholders on the reasons of its being. Leaders should always make policies that assist in the attainment of the mission of the company.

Creative Writing Essays (693 words) - Electricity, Free Essays

Creative Writing Essays (693 words) - Electricity, Free Essays Creative Writing It was a Saturday afternoon, and I was sitting in the living room recliner watching my normal morning cartoons while eating my bowl of Lucky Charms. All of a sudden, a newsflash appeared on my screen. A newscaster appeared and stated in a serious voice, "We interrupt this program for an important announcement. It has been discovered that a large meteor is traveling at a fast pace towards the Earth and has been calculated to hit the Earth at approximately 12:00pm, Tuesday. We urge everyone to move in a calm manner to a storm shelter or any other form of security." The Lucky Charms I had been chewing fall out of my mouth while the TV converts from the fear-inducing newscaster to Scooby Doo. I jump up in fear, and then embarrassingly realize that I had been dreaming. I sit down and wonder to myself, "What if that had really happened? What would I take with me?" In my opinion, medicine and electricity would be the most beneficial because of the advances and demands for the two ingenious discoveries. One hundred fifty years ago, in the operating theater on the top floor of the MGH's Bulfinch Building, one of the greatest moments in medicine occurred. On Oct. 16, 1846, William T.G. Morton, a Boston dentist, demonstrated the use of ether during surgery, ending the indescribable pain that had been associated with the surgeon's knife. Using a specially designed glass inhaler containing an ether-soaked sponge, Morton administered the anesthetic to Gilbert Abbott, a printer who had come to the MGH for treatment of a vascular tumor on his jaw. After several minutes, Abbott was rendered unconscious. John Collins Warren, MD, one of the most widely recognized surgeons of that time, then surgically removed the tumor. Upon wakening, Abbott informed the curious and skeptical physicians and medical students in the theater that he had experienced no pain. If it wasn't for a medical discovery like ether and other medicines, many would be experiencing the indescribably pain of the surgeon's knife and some would own a gravestone. Through the Renaissance, both men and women practiced medicine. For most of history, the human heart has been regarded as a forbidden organ, too delicate to tamper with. It might have remained so, if not for World War II. Military doctors, facing injury and suffering on a massive scale, pioneered advances in antibiotics, anesthesia and blood transfusions advances that would usher in the age of modern surgery. In addition to medicine, I would include electricity. Electricity, like light, travels extremely fast at 300,000 kilometers per second. It flows easily through metal wires. In particular, copper and silver are very good conductors of electricity. Electricity also generates heat as it flows through most objects. It can be controlled and utilized easily using many different technologies. Electricity is very useful because it can be converted into many kinds of energy. Electricity can be converted in to light using light bulbs, and even heat by using heating coils. It can also be converted into motion or even stored chemical energy. Electricity is used everywhere; to produce goods, provide services, and transport materials and people. Electricity also is used in commerce, agriculture, medicine, communications, entertainment, and a variety of other areas. Expanded uses for electricity are constantly being developed. Not only does electricity provide energy, it also provides jobs. A total of 510,595 workers were employed by electric utilities at the end of 1990 in a wide variety of jobs. From repairing power lines, to providing information to electricity customers, to constructing new power plants. These developments are driven by technological advances that both improve traditional uses of electricity and create entirely new ones. Because of the advances and demands for medicine and electricity, the great necessities would be beneficial to my survival. If it weren't for people like Benjamin Franklin or William T.G. Morton, we would not have such luxuries as heat or light, or some would not be enjoying the breath of life. If you take medications and electricity out of this world, you take out our culture and way of life.

Global Compensation Issues Essay Example | Topics and Well Written Essays - 500 words

Global Compensation Issues - Essay Example There exists laws that regulate salaries and wages and human resources professionals must act within the guidelines of such laws. This study will look at China’s compensation structures and compensation issues. China is a communist state in East of Asia continent. It has a population of approximately 1.39 billion people and fourth largest country in the world. China’s terrain is rugged with hills and depressions which include the Himalayas Mountains and the Turfan Depression. It has to main and important rivers namely; the Yellow River and Yangzi River. China experiences four weather seasons of summer autumn, spring and winter. During winter temperatures can drop to a level of -50 degree Celsius. China’s financial year is from 1st January to 31st December and had a GDP of 10.355 trillion US dollars in 2014 with its main industries being manufacturing, mining and food processing. China’s transport system includes railways, roads air and water. This makes most towns in this Republic accessible. The existence of navigable rivers has led to development of inland river ports and a reliable water transport system. The main mode of communication is telephone with approximately 23.68 Chinese citizens connected to telephone lines. The communist government in China has had a lot of influence in the country’s labor market. Regulation of the labor market through legislation has caused redistribution of the readily available labor in China. In order to improve the levels of production, the government initiated programs targeted at moving labor from low production sectors to high production sectors of the economy The large population provides huge supply of labor to China’s industries. In the earlier years, there was excess supply of both skilled and non-skilled labor. From the economics of demand and supply, the result was low cost of labor for different players in different industries
