Advantage and disadvantage of cell phone Lei Chen

As technology develops, nowadays the cell phone had become widely available to households in the world and it plays an essential role in our daily life. Advantage and disadvantage of cell phone become to be a highly charge issue in the world. Some people say that cell phone facilitation is benefit for our life. However, some other people think that the phone influences people normal life. So in this article, I’d like to talk about advantage and disadvantage of the cell phone.

 

Advantages

 

Cell phone really makes our life easier because of the following reasons. First, it has brought liberation from communication problem. 20 years ago, people used telegram and hand-free telephone to connect with friends or family. However, nowadays people are able to use a smart phone to contact with people at anywhere over the world in a fastest way. Secondly, with more scientific breakthroughs, cell phone is a multifunction tool nowadays such as calculator, surfer internet, checking and writing e-mail and so on. For instance, we can surf on the Internet whenever we like without opening a computer and whatever where I am. What’s more, it can also help us with some learning, because we can look up the word in the digital dictionary. Third, it is a strong entertainment tool. It is because people can use it to take photos, listen to music and watch movies. 

 

Disadvantages

 

Although our cell phones are more and more advanced, it still causes many serious problems. On one hand, there is no doubt, the most problem is electric wave radiation, which is bad for our health. For example, it can result in sleeplessness, endocrine dichasia and even cerebral cancer.   On the other hand, it will affect our learning, working and communication. Nowadays people like to plays phone all the time in work place, class and dining-table.   Contrast to communication of face to face, people prefer using phone to chat. So that in dining-table, many people play phone rather than taking with friends. In addition, according to CNN news, telecommunication fraud , which is the use of telecommunications products or services without intention to pay,  consistently increases.  People lost about 4.9 billion dollars in the US each year.

Technology:Good or Bad?__YINA

Topic: Internet : Good or Bad

WHAT IS THE INTERNET:
      The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is an international network of networks that consists of millions of private, public, academic, business, and government packet switched networks, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony.The network experienced decades of sustained exponential growth as generations of institutional, personal, and mobile computers were connected to it.
LIST OF BENEFITS:
    1.First of  all the use of the Internet offers a variety of benefits to everyone who is willing to use it. The enormous amount of information available and the many uses one can have through the internet have made it the most valuable tool in various settings of a person’s life. The Internet has an enormous amount of publications added on it every day and it’s evolving as the most powerful source of information.
  2. Furthermore, the widespread use of the Internet has opened new areas of jobs in all countries and expanded the availabilities of working from home. Last, the Internet is one of the most valuable tools in educations since it provides an enormous amount of information and is the greatest source of reference for educators and students. The electronic libraries are of utmost importance for University students looking for scientific information for their courses. Another major benefit of the internet is its ability to minimize distances and provide communication services efficiently and without any cost.  In general, the Internet is a multi-tool with applications on every aspect of someone’s life.
  3.Today’s needs and demands of society have taken over our time that feels it’s not enough for doing everything we need to be doing every day. The appearance of the Internet saving matter came as a life saver for many tasks that would take days to complete before. The ability of the internet to store materials, its ability to calculate instantly almost anything, and its worldwide application databases had made tasks much easier. and less time consuming in almost every industry on the planet.
   4.Transform people’s life and increase their knowledge
  5.The internet makes people's life convenient like the the internet bank and the internet market,internet shopping  can save you time and money since it offers a wide range of specials in much cheaper prices than what you will find in the actual stores.And people can also find a job on the internet .  6.One of the most important benefits offered from the wide applications of the internet is communication. The internet managed to eliminate distances and provide people with a unique opportunity to talk, watch and have fun with their loved ones, friends or acquaintances. Chat rooms, messenger services, emails and conferencing programs are the most common uses for communicating over the internet. People can enjoy the benefits of the cheap communication and maintain close contact with loved ones from all over the world.

  7.Teacher and students can find the learning material from it, prepare courses online and deliver audio/visual information.

LISTS OF HARMFUL:

   1.people also realize that Internet has a negative impact on people’s health and even emotions. It has been studied that people who tend to overuse internet are mainly teenagers. Excessive use of Internet not only affects teenagers’ health, but also causes some emotional problems, such as loneliness. Spending too much time on the Internet also deprives people of face-to-face interactions which might lead to some social interaction issues.

  2.In spite of the fact that internet as a new form of media almost phases out some traditional forms of media and serves as a communication technology that makes us able to talk to people from the other side of the world quite easily, there also comes a new symptom called internet addiction.  Internet addiction needs to be looked at in “psychiatric or psychological terms. Internet addiction has been reported to be related to loneliness, depression, harm avoidance, anxiety symptoms, impulsivity, and attention-deficit–hyperactivity disorde

  3. internet addiction may also lead to poor eyesight. Excessive internet use may also deprive people’s exercise time which makes some people in poor health condition. Even though the internet addiction is extremely harmful, the number of adolescents addicted to internet is still increasing.

  4..spending too much time using internet for interpersonal communication may greatly lower the quality of life as more internet communication means less face-to-face communication. The deprivation of face-to-face may directly lead to the degeneracy of communication skills because a deep communication involves eye contact and emotion dissolved in your voice; using internet to communicate is lacking of physical and emotional contact.

Nowadays,INTERNET is so important that we can hardly do jobs without it.But every coin has 2 sides,INTERNET also has many disadvantages. The details are as follows.
On one hand,INTERNET has many advantages.We usually search information or send E-mails for study for it can rise the working efficient.Online-shopping is a new and convenient way to buy things so that it is also popular among the young people.So we can inferm that the INTERNER has a lot of advantages.
On the other hand,INTERNET also has many poor sides.Spending so many time on online games is almost the worst.The result is that people may find they have less interest in the work and study and than getting in a poor circle.Another aspect is that lacking the face-to-face communication,the chatting and trade on the INTERNET become less and less believeable.So we can inferm that INTERNET has many disadvantages.
As the reasons concluded above, the INTERNET has both advantages and disadvantages.Only when we accept the postive aspects and get rid of the poor ones,the INTERNET will be our true and reliable friend.

Benefits and harmful effects on cell phone - Hannah

Benefits:

It is convenient for us to do some research instead of  turning pages of specific books in library. What's more, cell phones can be a learning tool for students since they can obtain much more knowledge with wider approach as well as explore the internet. To some extent, it helps us saving time.

We are all foreign students from every corner of the world, so homesickness is a problem that can not be avoided. Here comes another benefit of cell phone which is video chat. Via the advanced function, we can talk or even interact with our family and friends. Cell phone always allow parents and children to stay in touch. The sense of distance may be disappeared immediately. What would people do in the last century if they got homesickness? Holding an picture? Maybe it didn't work.

Moreover, by connecting mobile phones to the internet, we can always follow-up with the latest news. Compared to the past, 

Harmful effects:

The benefits that cell phone bring to us can not be ignored, but at the mean time, it indeed has some harmful effects. With the widely use of cell phone, lots of people seem to be addicted to it. Walk down the street and you'll see people everywhere with eyes glued to the screen. What does it mean? Maybe more and more people willing to pay time with their family. We are obsessed with checking in on Facebook and sharing about what a good time we are having now instead of making a phone call to greet our family.

More and more people become lazy nowadays, cell phone is one of the major element. People usually lay on bed and hold their phone to check in Facebook or watch movie with a fixed movement. What will the bad habit bring about? Obesity or 

What are the symptoms of a Heart Attack- Mohammad Alarji

Summary:

In the article,’’ What are the symptoms of a Heart Attack’’, by,’’ National institute of Health, NIH’’. The Heart attacks can start slowly and cause only mild pain or discomfort. Symptoms can be mild or more intense and sudden. Symptoms also may come and go over several hours. People who have high blood sugar (diabetes) may have no symptoms or very mild ones.

The most common symptom, in both men and women, is chest pain or discomfort. Women are somewhat more likely to have shortness of breath, nausea and vomiting, unusual tiredness (sometimes for days), and pain in the back, shoulders, and jaw. Some people don't have symptoms at all. Heart attacks that occur without any symptoms or with very mild symptoms are called silent heart attacks.

Comments:

Everybody should pay attention to these other possible symptoms of a heart attack: Feeling unusually tired for no reason, sometimes for days (especially if you are a woman), feeling sick to the stomach and vomiting. Any sudden, new symptoms or a change in the pattern of symptoms you already have for example, if your symptoms become stronger or last longer than usual). Not everyone having a heart attack has typical symptoms. If you've already had a heart attack, your symptoms may not be the same for another one. However, some people may have a pattern of symptoms that recur.

NUCLEARE POWER_____YIN JUHAO

TECHNOLOGY. What is technology? It is usually mentioned together with science.  What is the difference between them? In my opinion, science is a question about why, and technology is a question about how. Technology is a subject about how transform knowledge into productivity. Human progress is related with the development of productivity. So although  there are many harmful benefits about technology, everyone can not leave it. 

Today I want to discuss whether humans should exploit nuclear power. There is a great debate about nuclear power all over the world. Firstly，I think everyone who participate in this argument should clearly what is nuclear power? If you search nuclear power in Wikipedia, you will get the answer like this: Nuclear power, 
or nuclear energy, is the use of exothermic nuclear processes, to generate useful heat and electricity.(Wikipedia.com)

There is a great debate about nuclear power all over the world. 

There some benefits of nuclear power.

1.Nuclear power does not cause air pollution. 

2.Nuclear power does not produce CO2 which increase the greenhouse effect.

3.Nuclear fuels energy density are millions of times than fossil fuels. 

4.Nuclear power generation fuel cost is very low.

5,Nuclear power is the most secure way of generating in fact. In the process of coal mining, oil and gas,there are tens of thousands of practitioners has been killed.in the explosion and collapse of the accident.

There some harmful benefits of nuclear power.

1.Waste produced by nuclear power plants is radioactive.

2.The thermal efficiency of nuclear power plants is low, that will cause the heat pollution.

3.Nuclear power plant investment cost is too big, the financial risk of power company is too high.

4.Nuclear power plants is not appropriate to do with the load of the peak and off-peak operation.

5.To build a nuclear power plant is easy cause political disputes.

6.If released radioactive material into the environment in the accident, it will cause harm to the ecological and people.

Cell Phones: Good and Bad Sides__Faten

Summary:

Although Cell phone recently becomes widely used by all generation, it is a technology that has two sides. Many people oblivious the disadvantages of the cell phone, they believe that the cell phones have no bad effects. Here at this paper, I will discuss both the benefits and the harmful effects. First, there are many benefits of cell phones. Here are some of:

Cell phones help you to be connected. Cell phones change people live. In the past, people used to call their families and friends by standing in long line, spend long hours waiting for making STD or ISD call. Also, It Provides the benefit of sending messages which people can use when they can’t attend a call. Next, cell phones used as navigation. Recently, the cell phones are equipped with navigation and GPRS system. It helps people to find their way if they lost, and give the details about where they are. Another benefits come from the cell phones that it helps in legal matters. The police get the benefits of the cell phone to track the criminal by tracking the criminal’s cell phone to determine his place. The fourth benefit is, Cell phones can be used as entertainment tools. People can watch their favorite programs, News, Movies, listen to music, take pictures, recording videos, and play games in their cell phones.

Nuclear Energy in our life ! - Abdullah Alamri

 

Nowadays, technology becomes a major aspect in our life. Make our life going so fast and easy in some way. We create much technology proudest every year which is making us asks what will happen in the future by this much of technology. Many people don’t think every technology can be useful and helpful. However, some technology has many harmful effects, so they have become controversial. The following tow lists are about the positive and negative aspects of nuclear technology.

Advantages of Nuclear Technology (1) 

 1-Radioactive Waste

2. Powerful and Efficient  

3. Reliable 

4. Cheap Electricity 

5. Low Fuel Cost 

Disadvantages of Nuclear Technology (2)

Video Games - Abdulah Alzayer

The Technology now is something important in our life, because it helps us and makes our life better. Nevertheless, There are some technology have to become controversial. For example, Video Games, which some people think that the video games are something bad for kids and they make kids more aggressive. On the other hand, some people think that the video games improve a lot of thing in kid's life.

There are some benefits of video games such as : games improve the skills in the kids, games teach the kids another them language, games teach kids how to solve them problem, video games keeps every one happy. These are some of benefits of video games, but there are more.

      There are some people say that video games is not good for kids, and they have some reasons for such as play video games too much makes kids socially isolated, some video games teaches kids wrong things, if the kids play online , maybe they will learn bad word from the guys who play with them, and if the kids play too much, they will get bad grade in school.

      Gaming video or computers has positive as well as negative effects. Anything in moderation is not a problem. Parents and children need to be able to decide how much gaming is permissible and what kind of gaming.

      I think video games is Double-edged sword, if the parents teach them kids how to play with the right way, they will get a lot of benefits without harm things. So it depends on the family, but i think the benefits of video games are more than harms. There are many benefits of video games such as games improve the skills in the kids, games teach the kids another them language, and Sometimes possible to be a source of income.

“Guys, Your Smartphone Is Hurting Your Sperm” - Summary _ Natalia Carolina Camargos Ferreira

Summary

“It may be time to take the cellphone out of your pants pocket, gents”. This is the advice given by Alice Park, author of the article “Guys, Your Smartphone Is Hurting YourSperm”. As explained by Park, cellphone can cause harmful effects for the body, especially for the cell functions, because they emit low-level electromagnetic radiation (EMR).  According to the article a new research, analyzing previous studies, shows that sperm   samples exposure-to-cell-phone EMR lowered the mobility by 8% and mobility by 9% . This result can be explained by the fact that the man carry their cellphones in their pant pockets and this exposure to the EMR can  bring about an increase of temperature (up to 2.3 Celsius degrees) of the skin. This change in the temperature can significantly interfere with the hormone production. The author also mentions that how much the cellphone is harmful isn't totally clear yet. Thus, the best thing to do was to try to keep the cellphones away for the maximum time that you could in spite of this is a difficult thing to do in practice.

Comments

Cellphone are essential nowadays. It’s difficult to imagine our life without them nowadays since the time we wake until the time we go to bed, they are beside us. The cellphone allows that we can talk to everyone in any place of the world. They also allow us to have access to our email and research sources all the time we need. Without doubts, the cellphone is a very useful invention. However, some studies suggest that use of the cellphone can have causing bad effects in our body’s health. The main reason is because the cellphone works because of the electromagnetic radiation, and this one point that already is not so clear. Thus the best thing to do is to use the cellphone moderately. This way we avoid  the harmful effects of the cellphones.

Using nuclear technology good or bad---------Henry

How is Nuclear Energy Produced?

Nuclear energy is produced when an atom's nucleus is split into smaller nuclei by the process
called fission. The fission of large atoms, such as Uranium 235 and Plutonium 239, produces a great deal of energy. In fact, the fission of 1 gram of Uranium 235 produces the same amount of energy as the combustion, or burning, of 3 tons of coal (1)! The energy produced by the fission of uranium or plutonium can be harnessed to produce electricity, to propel space craft, and to power weapons like the Atomic Bomb.

Unlike a traditional coal-burning power plant, a nuclear power plant uses the energy, or heat, produced by the fission of Uranium, rather than the burning of coal, to heat water into the steam required to turn the turbines that power electric generators. The advantage of using Uranium over coal energy is that, unlike for coal, Uranium fission does not produce soot and potentially harmful gases such as Carbon Dioxide. However, like coal, Uranium is mined and then processed before it can be used as an energy source. Also, like coal, the different mining and processing steps, as well as the actual energy production, produce a great deal of waste. Unlike coal, however, these wastes are radioactive, and thus more difficult to handle.--------from internet

Good points

1.  There is a slight risk of accidental contamination.
2.  Not a lot of people have died because of nuclear power plants.
3.  Cleaner then fossil fuels
5.  Nuclear power plants have prevented 219 million tons of sulfur dioxide and 98 million tons of nitrogen oxides from being discharged into the atmosphere since 1973.
6.  In early 1998 the Natural Resources Defense Council, a leader in the battle against air pollution, reached a landmark agreement with New Jersey's Public Service Electric & Gas. The Natural Resources Defense council agreed to support the Newark-based utility's full recovery of investments in nuclear plants and other facilities that might be "stranded" by electricity deregulation. In turn, the utility said it would expand its energy-efficiency program.

Bad Points

 1.  Dangerous if it melts down.

 2.  Chance of contamination

 3.  Deadly

 4.  Cleaner forms of energy can be formed, if more work was put into them, like fusion.

Nuclear Power Technology_Kate

       Nuclear technology is technology that involves the reactions of atomic nuclei. Among the notable nuclear technologies are nuclear reactors, nuclear medicine and nuclear weapons. It is used in smoke detectors and gen sights.

I’m going to describe you about nuclear power which is about weapons.

There are many benefits of nuclear power.

The main advantage of nuclear power has over other method is that is a clean way to produce energy.

It does not result in any poisonous gases like carbon dioxine,sulfer dioxine or nitrogen dioxine.

The nuclear waste is not only small quantity but also remains confined  that is not affect anyone in its surrounding. It would be as small as a golf ball. The disposal of nuclear power waste is easier than chemical waste because it is only jump dumped into a geological site that has no negative impact in the ecosystem. Nuclear power is very safe.

It’s an extremely dependable source of power because most of nuclear reactors have a life cycle of 40 years.

The biggest fear with nuclear power is the fear of radiation. If there is a nuclear power plant near your business or home. The amount of radiation emitted from a nuclear power plant is less than 1 millirem per year. Workers inside of the nuclear power plants are limited to the amount of radiation so that they are exposed and are monitored for safety. People would be surprised to know that radiation can be advantageous to our health. The nuclear power is being support by many ecological organizations and environmentalist.

What are the disadvantage of nuclear power?

Nuclear Accident : The risk associated with nuclear accident are relatively high. People who work at nuclear power plants live near nuclear station so they have high risk of facing nuclear radiations if nuclear accident happens.

High cost : Nuclear energy needs a lot of investment to set up nuclear station. Nuclear power plant normally take 5-10 years to construct ,and it is opposed by people who live nearby.

Non Renewable : Nuclear power uses uranium which is limited resource. Uranium is not find in many countries.Supply will be available as long as it is there. Nuclear plants will not be of any use. It can not be term as renewable.

The consequences of global climate change___Lei Chen

LINK：http://climate.nasa.gov/effects/

Summary

In the article, “The current and future consequences of global change”, the author explains that Global climate change will cause all kinds of effect. First, the author says that according to scientists’ forecast, global change will lead to a lot of disasters. Primary reason is human activities which engender abundant greenhouse gas, so that temperature increased. Secondly, the writer shows that IPCC thinks that environment will base on climate change to adapt or to change. The reason is that less than 1.8 to 5.4 degrees Fahrenheit increased not only has some bad effect, but also has a little bit benefit. Third, the author shows that global changes forecast based on IPCC in order to slow down global warming. The IPCC claims that as temperature increased, management cost will consistently increase. Fourth, the writer shows the forecast of global. North America will be decreased 5-20% snowpack. And Latin America can occur species extinction. Europe can cause many floods, storms and glacial retreat. In addition, in Africa, plenty of crops will be destroyed. In the Asia, droughts and disease can influence people life. In the end, the author uses two forms to explain recent and impacts and future trends of global climate change.

Comments

As economic and society develop, global warming has become a hot topic in the world. If this problem does not be solved, human will face a huge disaster. The car and factory discharge countless carbon dioxide. Plenty of plants, forest are destroyed. Natural self-control cannot follow development of human. So what can I do?

From TV, magazine, internet and so on, everyday we are able to see a lot of AD or discussion, however, nobody care about it. Just saying, but do not real do it. As population constantly increasing, government has to sacrifice environments in order to supply the demand of people life. On the other hand, a sense of environmental protection needs to develop.

As a university student, I suggest that first, government should enhance to supervise. Second, education system should train children sense of environment. Third the adults should have a sense of crisis. Nowadays development of society based on descendant environments. Don’t give descendant an evil environment.

The Harmful Effects of Sunlight sarah

The Harmful Effects of Sunlight

 

Ozone layer depletion reduces our atmosphere’s natural protection from the sun’s harmful ultraviolet radiation. That depletion will lead to increase the ultraviolet (UV) radiation that you can’t see or feel.

It affects human health both positively and negatively. The (UV) radiation has many effects to the human health both positively and negatively. Especially for people who spend unprotected time outside home .in this summary I will explain the effects that could happen because of these radiation .Such as , Skin cancer ,Cataracts ,Suppression of the immune system and Premature aging of the skin.

First of all, skin cancer is unnatural growth of skin cells .that leads to form malignant tumors. All that happened because of the ultraviolet radiation that person exposed himself. According to, American cancer society, More than 3.5 million cases of basal and squamous cell skin cancer is diagnosed in USA each year. Melanoma, the most serious type of skin cancer, will account for more than 76,000 cases of skin cancer in 2014. They notes skin cancer is the most common of all cancer. Exposure to UV radiation is the most important environmental factor in the development of skin cancer. The skin cancer is a dangerous disease that could lead the Infected to die. Second effect, Cataracts or eyes damage, the sun is the only source of UV radiation which could damage our eye tissues if we exposed to the sun for a long time without any protection. Also sun radiation cause Suppression of the immune system  the Scientists believe sunburns can affect in alter the distribution and function of disease fighting white blood cells in humans for up to 24 hours after exposure to the sun. As a result, Repeated to much to UV radiation can cause more damage to the body's system. Finally, premature aging of the skin is the easier disease could happen to a lot of people. Staying overexposure to the sun changes the texture and weakens the properties of the skin. Actually, Premature aging of the skin is cumulative of gain the skin cancer that means you have to be more careful and start a sun protection program.

Effects of air Pollution- Mohammad Alarji

Summary:

According to the article,’’ Effects of Air Pollution.'' by,'' http://eschooltoday.com/pollution/air-pollution.''  Air pollutants can be in the form of particulate matter which can be very harmful to our health. The level of effect usually depends on the length of time of exposure, as well the kind and concentration of chemicals and particles exposed to. Short term effects include irritation to the eyes, nose and throat, nausea and allergic reactions. Short term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long term health effects can include chronic respiratory disease, lung cancer, heart disease and even damage to the brain, nerves, liver or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.

Comments:

Solution efforts on pollution are always a big problem. This is why prevention interventions are always a better way of controlling air pollution. These prevention methods can either come from government (laws) or by individual actions. In many big cities, monitoring equipment has been installed at many points in the city. Authorities read them regularly to check the quality of air. Government or community level prevention; governments throughout the world have already taken action against air pollution by introducing green energy. Some governments are investing in wind energy and solar energy, as well as other renewable energy, to minimize burning of fossil fuels, which cause heavy air pollution. Governments are also forcing companies to be more responsible with their manufacturing activities, so that even though they still cause pollution, they are a lot controlled. Pollutants facts companies are also building more energy efficient cars, which pollute less than before.

Individual Level Prevention; pollutants facts encourage your family to use the bus, train or bike when commuting. If we all do this, there will be fewer cars on road and less fumes.
