Communication Process Paper Essay Example for Free

Communication Process Paper Essay Communication process is a very important aspect with the help of which people send messages verbal including sentences, words, and messages nonverbal including physical setting, facial expression, and behavior. Communication patterns have changed because of changing nature of interaction between people. Communication allows business to coordinate and unify common goals. An open communication policy in business where the employees may come to the supervisors and voice his or her likes as well as dislikes. The business will have a workable environment for everyone. As the message passes through this medium, there is noise and which changes the message into something different from what was sent. These are otherwise known as the barriers to effective communication. Noise can be static or anything that distracts from the intended massage. Example, if there a meeting going on in the workplace and two employees are talking in the background. An individual will become distracted of what the meeting is about. Communication process Paper The climates in most workplace are cool if it is an inside job. So individual may be comfortable communicating with one and another. Some people believe the environment tan make a difference with the way an individual communicate. Communication is vital in the workplace and it the primary means to convey the proper message. Most jobs have shift work and needs to communicate from one shift to another. This may be done by verbal or written in paper. A business climate most likely creates within levels of management and spreads from there. The strength and weakness of any organization are only good or bad as the individuals who work there. If there an open policy where employees can communication with his or her supervisors as they please. This procedure will make the workplace environment workable for everyone. Every employee in the workplace should voice his or her opinion toward the supervisor without been afraid of the outcome. Everyone has some weaknesses and strengths in communication as a result of psychological and personal peculiarities, and every day communication patterns. Verbal written communication is my strength. My weakness is nonverbal communication because in some situations I am not sure what behavior patterns I should follow, for instance, speaking with strangers, or the police. Sometimes I believe cultural or social barriers communicating with others, I have strong verbal communication skills because I spend much time communicating with my friends on the Internet. This way I can communicate with several people at the same time, and save time on phone calls or visiting them. This form of communication is very popular because it transmits information to the individuals and receives reply rapidly. I have good written skills and can clearly express opinion in several sentences. This strength is logical, concise, and informative messages, which help the recipient to grasp the idea at once. Good written skills used in the criminal justice system and other business. Years ago the senior management committee of some business, there strategies for doing everything from changing policies to dealing with employees discussed behind closed doors. Once those decisions made by management, the supervisors were asked to put those decisions into effect. The employees had little to no input on those matters. The employees did as they were told or had to find a new job. Today some management team members listen to what the employees have to say before making a decision on changing the policies. Most business in the present encourages employees to take an active part in their company. The employees who work on production line may know some ways to improve the lines. Some manager may pass out certain type of rewards for his or her ideals. Communication process with employees can be a difficult task. It may take knowing what an individual have to say to communicate in a way to receive desired result. Communications to employees come from several areas within the organization, the director, human resources, the program manager, and other management team. Every employee need to know what is happening within the company. The company will not achieve if the employees are not contribute what expected of him or her. That why a well-organized internal communication strategy required to create the ideal mindset within the company.

SIP Security Essay -- Information Technology

Abstract The session initiation protocol (SIP) is emerging as standard protocol for session control in Next generation voice over internet protocol (VoIP) As it is based on IP it is vulnerable to all IP related threats . Among all the attacks, flood-based denial of service DoS attack is one of the main threats to SIP. Several solutions regarding prevention of DoS are discussed. Efficient Security scheme is proposed for batter performance. I. INTRODUCTION Session Initiation Protocol (SIP) [1] is signaling protocol given by the Internet Engineering Task Force (IETF) for IP telephony. Moreover, the 3rd generation partnership program (3GPP) has chosen SIP as a signaling protocol in IP multimedia subsystem (IMS). With more and more multimedia applications and the digital audio/video transport over IP-based networks, SIP is becoming the de-facto signaling protocol. In fact, SIP is a session control protocol that can establish, modify, and terminate multimedia sessions such as Internet telephone calls (VoIP). SIP users are indicated by Uniform Resource Identifiers (URI), consisting of a pair of user name and domain name, e.g. sip:ali@abc.co.uk , which is similar to the email format. SIP signaling between multiple users consists of requests and responses .A call is set up in SIP by the three-way handshake composed of INVITE, 200 OK and ACK messages. The INVITE request asks the cal lee to join or establish a call. If the cal lee’s response indicates that he/she accepts the call by sending the 200 OK response message, the caller confirms that it has received the response by sending the ACK message. When the caller or cal lee wishes to terminate a call, they send a BYE request. ... ... June 2001. [8] T. Peng, C. Leckie, and K.

The Cause and Effects of Global Issue

The cause and effects of global issue Because of the development of technology, which people use to treat diseases, the deaths caused by communicable disease are decreasing all over the world. However, the deaths of Non-communicable diseases increase. Non-communicable diseases such as Diabetes, Cardiovascular diseases (CVD) and cancer, which are caused mainly by the bad lifestyle result in the burden to the global economy and caused many deaths in the whole world. In this essay, firstly, the causes and effects of Diabetes will be introduced.Secondly, those things of CVD will be demonstrated. Finally, the Cancer’s cause and effect will be discussed. Diabetes is a quite widespread disease, which is caused by the lack of an important hormone called insulin. However, researches show that people who exercise less, insobriety and smoke more possibly get this disease and these factors are the primary causes of this disease (Colditz 1990, Helmrich 1991, Lynch 1996, Manson 2000, Ajani 2000). Because of the spread of this disease, people all over the world were greatly affected and it mainly includes three aspects.Above all, diabetes widely affects our health and daily life. Up to now, it’s still hard to cure diabetes. Diabetes has an excessive morbidity. DIABETES UK (2010) estimates that in 2009, 2. 6 million people in the UK were found to have diabetes and it predicted that the number would increase to 4 million people by 2025. Not only, in the UK, diabetes is also a big problem in the US. In a research (2011) shows that 25. 8 million people in the United States suffered diabetes, which represents 8. 3 percent of the total population. In other developing countries, the situation is even more difficult.In addition to the extremely high rate, diabetes always leads to other diseases like heart disease, High blood pressure, blindness, kidney disease, nervous system disease. In 2004, 68 percent of people older than 65 who were died from heart disease turned ou t to have relationship with diabetes (2011). From the year 2005 to 2008, 67 percent of people who suffered diabetes have greater blood pressure than the equal level (2011). Besides, diabetes is the leading factor of factors of blindness. In 2008, a total of 20290 people were living on kidney disease in the United States.Most of them have the history of diabetes. What’s more, about 60% to 70% of people with diabetes have a tendency of developing into nervous system disease (2011). Finally, it is also an economic issue to both governments and individual. ‘The Cost of Diabetes in Europe-Type 2 study’ is the first coordinated attempt to measure total healthcare costs of Type 2 diabetes mellitus in Europe. It evaluated more than 7000 patients with Diabetes in eight countries which shows that the total costs of diabetes were estimated at the EUR 29 billion a year(Jonsson,2004).It has the same situation in other countries all over the world. In Canada for 1998, the econ omic burden of diabetes was likely to between $4. 76 and $5. 23 billion(Keith, 1998). In Sweden, the prevalence of diabetes mellitus is about 3%-4% of the population. The economic burden of diabetes is estimated at 5746 MSEK in1994. (Jonsson, 1983) CVD are the most common complication of diabetes: diabetes causes the microscopic blood vessels of the heart which brings myocardial necrosis. In addition, it also causes atherosclerotic which contributes to coronary heart disease.Myocardial necrosis and heart disease both are a kind of CVD (Goldberg, 2000). Not only are CVD caused by diabetes, but also both of them have something in common. It shows clearly the connection between CVD and unhealthy lifestyle as diabetes does (Wright, Douglas, Rahman, 2004). In other words, unhealthy lifestyle is the main factor of CVD. Unhealthy lifestyle is reflected in using of tobacco, unhealthy diet, lack of exercise and staying up late. On the one hand, with the development of social economy and the living standard improving, people have sufficient money to purchase tobacco.Consequently, tobacco is introduced into people’s life. It has an enormous negative effect on human’s health and is also one of incentives of CVD (Millett, Gray, Saxena, Netuveli, 2007). As another effect of society progress, diet style has changed a lot: people’s staple bread has changed into the high adipose and high protein instead of grain and vegetables (W. H. O. , 2005). Fat intake more than reasonable limit intake, which was the main factors of nutrition superfluous. Over nutrition causes overweight and obese people greatly increases.Overweight and obesity are the common risk factors of CVD (W. H. O. , 2005). On the other hand, the quick pace of city life produces lack of exercise and staying up late. Lack of exercise causes the obesity, hyperglycemia, hypertension and hyperglycemia ( Furberg and Thune, 2003). It has been reported by Furberg and Thune (2003) the main risk factors of CVD are hyperglycemia, hypertension, hyperglycemia and obesity. As a result of staying up late, people usually feel ill next day. Phillips (2005) explained the reason why people feel sick. It is because staying up late engenders endocrine disorders.In addition, endocrine disorders will cause atherosclerotic cardiovascular disease, which is one of CVD (Phillips, 2005). Although the decrease of the death rates from CVD appears in some part of western countries (Slattery, Jacobs, Nichaman, 1989), it is still one of the most serious threats to humans, especially among the seniors, in developed countries where medical equipment and technology is comparatively advanced(W. H. O. ,1993). That means the current state of CVD is not that positive as it seems to be. CVD is still one of the deadliest diseases in most parts of western world.Statistics demonstrate that More than 30% of deaths in the United States were caused by CVD (Pakenham, 2010). To make matters worse, the disease, which con sidered to be solely happening in the western world, now spread to the developing countries and is becoming a worldwide leading cause of death (W. H. O. , 2005). Take China as an example, the number of patients with CVD reached 230 million in 2008, which means that 2 in 10 adults are suffering from cardiovascular disease (The Ministry of Health, 2010). As a whole, this kind of problem still remains a challenge for human beings (Pakenham, 2010).CVD not only causes large quantities of death, but also increases the enormous economic burden. People who have contracted this kind of diseases suffered unbearable cost pressure including expensive cost of drugs, of undertaking body examinations regularly and of surgery. In 2010 in China, as far as cardiovascular disease is concerned, the acute myocardial infarction costs Chinese society 1. 946 billion Yuan, while 6. 587 billion Yuan in intracranial bleeding and 9. 817 billion Yuan in cerebral infarction. (The Ministry of Health, 2010).Accord ing to China cardiovascular disease report(2010) despite of the fact of price changes, a respectively average annual growth rate of acute myocardial infarction, intracranial bleeding and cerebral infarction respect attained 34. 46%, 26. 85% and 31. 05% since 2004. China cardiovascular disease report (2010) stated that such a rapid growth of cost of CVD have a close connection with the rapid growth of the number of people and increases personal and national economic burden. Be similar to diabetes and CVD, the cancer spread very wide and quick and influence seriously. There are many factors, which can cause the increasing of Cancer.The main factor is the unhealthy lifestyle, such as alcohol abuse, inadequate diet, physical inactivity and tobacco’s use. Tobacco’s use, which has the biggest influence on human causes highest rate of cancer. The more and more use of tobacco causes the increasing of lung cancer, which has a high fatality rate. According to the J Natl Cancer I nst (1981), by far, the largest reliably known percentage is the 30% of current U. S. cancer deaths that are due to tobacco. On the other hand, the physical inactivity also causes the increasing of cancer, because the cancer is from the genic mutation.If people do fewer exercises, the more rate of genic mutation will be. So people will have a higher rate of getting cancer. Moreover, the pollution of environment causes the increasing of cancer too. It even can cause 37 forms of cancer (core-reading. No date) Because of the increasing of the cancer described above, it costs much money and influences the economy. This phenomenon not only occurs in developing countries but also in developed countries. According to the Boyle (2008), this is going to present an amazing problem at every level in every society worldwide. However, the influences in different countries are different.For example, the cost of cancer in the United States is less than 1. 73% of GDP but in the Hungary, which has a smaller population and domestic economy it is more than 3. 05% of GDP. (Global Health, 2010) This kind of difference between developing and developed countries is the result of the different degree of attention in the countries. In developing countries, the government pay more attention to the development of economy thus the control of cancer was ignored. Only when cancer becomes an evident disaster, the government will turn to treat it. However, it will cost more money, because the treatment costs more money than the prevention.The truth is that both developing and developed countries spend much money on cancer. The total economic impact of premature death and disability from cancer worldwide was $895 billion in 2008. This cost represents 1. 5 percent of the world’s gross domestic product (GDP). This economic toll from cancer is nearly 19 percent higher than heart disease, the second-leading cause of economic loss ($895 billion and $753 billion, respectively). (Global healt h, 2010) The high cost of cancer happened because the cancer has direct and indirect influences on the economy.The direct influences include the cost of treatment and prevention of cancer and the funds which be used in research of cancer. The indirectly influences is the decrease of the productivity, because there are no longer enough healthy adults who can work for the industry. Moreover, the death of cancer is more than any other disease, especially in the developing countries. People in Butler County are more likely to die from cancer than heart disease, counter to the trend seen nationally and across the region, according to Journal News’s examination.In some developing countries, the cancer death can equal or larger than 60% of the total death in there per year(Boyle,Levin,2008). In 2008, there were 12. 4 million new case of cancer diagnosed and 7. 6 million deaths from disease (Boyle,Levin,2008). There are a number of factors, which account for the increasing of Non-com municable diseases. However, the main factor is the bad lifestyle of people. On the other hand, the Non-communicable diseases cause many deaths and loss of global economy. It has been argued that there are three kinds of Non-communicable diseases, including Diabetes, CVD and Cancer, which play the important role in NCD.These three diseases caused by the bad lifestyle such as the lack of the exercise and the superfluous or unhealthy diet. Because of the increasing of the NCD, it cost a lot of government’s money to treat it and becomes a heavy burden to the global economy. All in all, the Non-communicable diseases as a global issue result in the burden with the global economy and cause many deaths in the whole world.
