My first volunteer trip was in June 2020 at an orphanage in Hanoi. The orphanage is housing children without parents from different regions in our country.  It provides medical care to children, education, food, and other necessities. At that time, my uncle who was a founder and chairman of a charity in Hanoi, told me to join this activity. I love children so I never hesitated to join. On the day of our visit, we brought food and clothes to the kids. In addition,  we held some activities such as playing games, singing, dancing,… It was a lovely experience seeing kids be wreathed in smiles. The selfless act of volunteering also provides a spiritual enhancement to me.

Mid-Autumn Festival is under the full moon day of the lunar calendar every year in August, over 4,000 years ago. This is the day children’s festival, also known as the “Festival looks Moon”. Children are expected Tet is because adults are often donated toys, usually light. His star, mask, light pull troops … and pies, cakes plastic. Besides the Tet Holiday, Mid-Autumn festival is one of the most famous festivals and it is a traditional celebration for Vietnamese children.

In this new year, we organized presentation deck, looks moon. Everywhere is fallen in the active and colorful air. Children are provided with many nice lanterns – star lanterns, flower lanterns and diverse funny masks for special performance in the evening of the full moon. In some areas, people also held dragon dance, lion dance to the children happy. The main point of the Mid-Autumn is that children use the beautiful lanterns, wear funny masks, perform fantastic lion dances and sing folklore songs in the house’s grounds or on the streets when the moon is rising.

In Vietnam, Moon cakes are the specific cakes and are only on this festival. Moon cakes, which are made from flavor, dried fruit, meat, egg, pumpkin’s seed, peanut, are so sweet and good tasting. Moon cakes symbolize Luck, Happiness, Health and Wealth on the Mid-Autumn day.

Mid-Autumn celebration is also an opportunity for members of the family to get together and share everything in their year. The young generation express their gratitude to the old generation. The parents show their love for their children. For others, because the traditional time to have this festival is usually after harvesting the crops, it is as the congratulation for the full harvest.

Apart from moon cakes and lanterns, the other most visible tradition related to Mid-Autumn festival is the lion dance. On the nights leading up to the holiday, groups of children parade through the streets – some of the children maintain a martial beat on drums, while others control an extravagantly decorated ‘lion’ crafted from molds and paper.

The children approach homes and businesses and ask the owners for their permission to perform. If they agree, the children put on a show that is believed to bring a blessing of luck and fortune. Afterwards the host gives the children lucky money as a sign of gratitude.

It took hundreds of thousands of years for the world population to grow to 1 billion. However, in just another two centuries, it grew sevenfold. You know, in 2011, the total population of the world reached 7 billion. And today, it's about 7.5 billion. Tokyo, with 37.8 million residents, continues to be the largest city in the world in terms of population.

Advances in modern medicine are the main cause of this dramatic growth in the world population. It helps the birth rates increase and the death rates decline. The second contributor is the improvement in living standards. This leads to the rise of global lifespan, from 64.8 years in the early 1990s to 70.0 years today. Last but not least, the number of women of reproductive age is increasing day by day.

However, the rapid population growth can lead to the shortage in medical and educational facilities and services. The population grows fast so the demand for energy also increases.Therefore, energy shortages are also a big problem. In addition, air, water and land pollution caused by growing population in big cities has bad effects on people's health.

Spending time in an English-speaking country is a really essential experience for the English-learners as well as the best way to study the language. However, I believe that there are many other strategies for learning English, which are useful enough.

In the first place, studying in an English-speaking country such as Australia gives you a variety of opportunities to improve your speaking and listening skills. Moreover, you practice your English while doing ordinary things, for instance, shopping. Consequently, you become more self-confident. Being overseas is the best way to learn the language effectively.

Secondly, providing that the learner is hard-working enough, they can learn English even in their own country. The English Language Schools provide their students with a wide range of opportunities to master the language. Furthermore, there are different methods to practice your skills such as watching English television, reading English books, magazines, etc. The combination of some of these methods might be a really useful strategy.

In conclusion, there are many advantages of living in an English-speaking country as this is the best strategy to learn the language. Nevertheless, if the student is responsible and works hard, they can achieve success in studying English not only in a country where the language is widely spoken.

Sifting through his latest screenplay on the way to class, Geoff Yetter ignores the muffled sound of a computer-generated rendition of Johan Pachelbel’s Canon in D coming from inside his book bag.

“Porcupined onions,” he curses to himself. “I’ll call them back when I’m free.”

Yetter, a senior film and video studies major at the University of Oklahoma, said that although he has a cell phone, it is only because he considers them to be a “necessary evil.”

“At the risk of coming off as one of those ‘hippie’ types, I truly see a cell phone as a leash that ties you to a world that man shouldn't belong to,” he said. “No matter how much one tries, you can never escape anyone if you have a cell phone.”

Over 110 million Americans own a cell phone, according to a study done by the Cellular Telecommunications Industry Association (CTIA). With an average of 46,000 new subscribers every day, CTIA experts project that in 2005 there will be over 1.25 billion cell phone users worldwide.

Increasing numbers of college students are abandoning landlines in lieu of simply using their cell phones as their only contact number, said an Oct. 10, 2004 Wesleyan Argus article on the drop in dorm phone subscription rates at Wesleyan University. The article calls the drop so significant that landlines on campus “seem anachronistic.”

In a school like Northeastern University,a fast-paced, career-driven school in a major metropolitan area, having a cell phone is almost a necessity for students.

While there are many factors to consider when deciding to purchase a cell phone – convenience, price, minute plan, clarity of service, when it will be used, health risks– it comes down to a simple necessity of a convenience for most people, said the Argus article.

“I have my cell phone to keep in touch with friends and family from home,” said Kirsten Baxter, a junior mechanical engineering major at Northeastern University. “My family lives on the West Coast so it would be long distance on a regular phone so I (set up) a cell phone plan with nationwide minutes.”

Having a cell phone also makes more sense for her as a college student because with a landline she might have to set up a new number every time she moves in addition to it being obviously less portable, she said.

Many newer cell phone models are multimedia devices with “telephone” merely being one of the features. There are camera phones and various videogames and ring tones one can use on a cell. There is also the Nokia “N-Gage,” a gadget that is primarily a handheld videogame system that doubles as a cell phone and can be used to play multiplayer games across a cell network.

“I like having the games on my cell phone a lot because I commute too,” Baxter said, peering up from her match of cell phone Backgammon. “When I’m on the T it’s nice to have a mindless game to play.”

Health Concerns
The radiation emitted from everyday cell phones in extended exposure has been proven to cause an increase in lymphocytes in mice through lab experiments, according to a study done in Radiation Research – a monthly journal published by the Radiation Research Society. Yet there is still no definitive answer on what the long-term health risks for humans may be.

“There have been several studies that examined this issue and reported that there was no significant difference in the incidence of brain tumors in cell phone users and non-users,” said Professor Robert Cersosimo of the Bouvé College of Health Sciences at Northeastern University. “However, there is more work to be done is this area and more studies are currently underway.”

While some students do consider these health risks and remain leery of them, others do not give them a second thought and spend literally thousands of minutes on their handheld phones every month.

“I sometimes worry about the risks of developing some kind of tumor from using my cell phone too much,” said Northeastern sophomore pharmacy major Jack Soohoo. “But it doesn’t stop me from using it.”

Soohoo estimates he uses his phone an average of 15 minutes each day – almost 500 minutes a month. That amount may be enough to do damage, but considering it as only a mere 15 minutes out of the day might be enough to create a false sense of security for users looking to rationalize the use of their phones in some way.
“I think the amount of time I spend using my cell phone is still insignificant and won’t be sufficient [enough] to cause cancer,” said Soohoo.

Baxter has similar feelings, saying she thinks “common sense says it has the probably could cause cancer, but everything does” and that she’s not overly worried about it.

For those who do worry about the risks of radiation waves being transmitted close to their heads, protection devices exist that are intended to cut down on this potentially harmful radiation.
The “No-Wave – Anti Wave Antenna” technology by RF Safe incorporates “a simple natural process of nullifying energy around the user through an Interferometric Array or interference pattern that sends in-phase and out-of-phase energy to cancel each other out at point of intersection,” according to the company’s website.

The safeguard system was invented to prevent possible health effects and as a solution for an FCC mandate of the Americans with Disabilities Act to create a device that would let hearing impaired individuals to use cellular phones without having to remove their hearing aid.

According to the company’s website, radiation emitted from a cellular device penetrates into the skull of the user’s head while remaining at high levels, above that of the federally imposed Specific Absorption Rate (SAR) guidelines (Fig. 1). The image, which was created using electromagnetic imaging software, shows a reddened region surrounding the ear representing the reach of the most intense rays.

RF Safe claims their RF blocking device can significantly reduce this reddened region. When a phone is placed next to a handheld RF meter during a connected call, the radiation levels spike toward the highest readings. After the company’s protective device is equipped, the reading is significantly lower (Fig. 2). Whether or not these images are skewed to assist the company’s image, the radiation levels of an unprotected phone are still elevated.

Greta Merrick, a sophomore graphics design major at Northeastern who is opposed to owning a cell phone, said that while such data is frightening, the health risks are not a determining factor and something she “honestly wouldn’t consider that much.”

“I don’t know much about the health concerns,” she said. “I’ve only heard hearsay.”

For alternative methods of reducing exposure to radiation from a cell phone, the National Cancer Institute suggests reserving usage for only shorter conversations and in situations where a landline is not available, switching to a type of portable phone with a headset to keep the antenna away from the head, and for use in a car, switching to a kind of mobile phone with the antenna mounted outside the vehicle.

Multitasking
With the added portability cell phones offer, they can assist a businessman in getting added work done while on the run. They can be the charm a commuter student studying on the train needs as he makes arrangements for later that night, or they can serve as the liaison for a stock broker trying to get some extra buying and selling done while driving to lunch.

While this handiness can certainly increase the efficiency of and be a benefit for many people, the distraction that comes with this convenience can be dangerous.

“Studies have confirmed that people who use a cell phone while driving run the same risk of having an accident as a moderately intoxicated person,” said Professor of Northeastern University’s Sociology and Anthropology department Danny Faber. “In other words, holding onto a cell phone (with one hand) while driving with another dramatically increases your chance of having an accident.”

Driving while talking on a hand-held cell phone doesn’t just slightly increase one’s chances of getting in an accident, it increases those chances four-fold, according to a study done by the New England Journal of Medicine. That statistic is comparable to the one found regarding the increased occurrence of accidents among those driving while under the influence of alcohol.

As much of a potential hazard as this can be, 56 percent of college students surveyed at Northeastern University said they talk on their cell phones in the car all the time. On top of that, only six percent said they have never taken this liberty.

Professor in the Sociology and Anthropology department and Acting Chair at Northeastern Thomas Koenig said he thinks this shift in public phone conversations is, if nothing else, strange.

“I think it is interesting that people used to go into full booths (to talk on the phone in public),” said Koenig, mentioning where Superman changed in the old TV show as a reference. “Privacy and not bothering others was very important. Now people think little of blabbing their personal business to everyone passing nearby.”

With all this multitasking has come people taking their conversations into public places, often bothering those around them.

"Cell phones are still a pretty new technology," said Dr. Jack Levin, Professor and Director of the Brudnick Center on Conflict and Violence and Professor of Sociology at Northeastern. "We haven't yet developed norms for use. Some think it's okay to use in work, some think it's safe to drive (with one), some think it's okay to talk loudly in a crowded elevator."

Not as intimate
Merrick said that the main factors keeping her from using a cell phone are less about health and more about the cost and, chiefly, the lack of intimacy in conversing with someone on the go.

“They might be walking down the street or be at a party or in a hurry,” she said. “If they don’t tell you, you could start pouring out the story of your day and they can’t pay attention but they try to anyway.”

Merrick said she prefers the comfort and familiarity of using a home phone.

“If someone’s on a landline, you know they’re in their home – in their personal space, talking to you and listening to you,” she said. “The first question I usually ask someone if I’m calling their cell phone and actually want to talk to them is ‘Where are you’ or ‘What are you doing’ because otherwise I can’t relate to them and how can you talk to someone you’re not relating to?”

Professor Faber also prefers to remain living as he did before the inception of cell phones into society. While he said he believes one may certainly be risking one’s health when using one of the handheld devices, he mostly wants to be reached when he is in position to be reached – at home or in the office.

“I value my privacy, and don't want to be so accessible all of the time,” he said.

Yetter said he often feels the same way when he hears the beginning of the digital Canon in D, and resents the expectations of being available all the time to concentrate on a phone conversation.

“Anyone can track you down at any time, and when they are unable to, they get cross with you because they believe that, since you do have a cell, they are entitled to talk to you whenever they wish,” he said.

Yetter, like Merrick, says he also doesn’t consider the potential adverse health effects as one of the main deterrents.

“For me personally, I am unafraid of the health risks because I use my phone so little,” he said. “But as research developments continue and further evidence proves that these gadgets can be cancer-causing, it does make me worry for friends, family, and, well, everyone who uses one basically.”

Cost
Over 70 percent of college students who own a cell phone do not pay for their own bill, according to the survey conducted at Northeastern University.

Of those surveyed, only two of the 18 respondents said they actually pay for their entire bill, while another three either pay some of the bill each month or only in situations where they incur overage charges.

Most cell phone companies offer plans upon which customers pay a fixed rate per month and are given a set amount of minutes to use within certain time constraints. The most common plan cost of students surveyed is $39.99, yet one-third of students said they do not even know how much their cellular phone costs per month. T-Mobile and Verizon were both the most popular and highest rated services on a scale of one to 10, each garnering an average rating of just under 8. If the user goes over his or her allotted minutes, the user will have to pay overage charges, which typically range around 40 cents per minute.

In some cases, these excess charges for using more minutes than agreed upon in a contract can run up a steep bill. Sophomore journalism and marketing major Bessie King said one month she received her bill in the mail and was surprised upon opening it up to find a bill of $300.

All she could say to describe the situation was, “Ouch.”

In addition to the monthly expenses that come with the territory of owning a cell phone, buying a phone itself can be expensive too. While most wireless carriers offer free phones for signing up, the upper echelon sets, like the Samsung “i600 Smartphone” from Verizon Wireless that costs $549, can still strike a hit to the wallet.

While phones like this incorporate many added features like Microsoft Windows Mobile and can surf the internet, the result of owning one is carrying around a valuable piece of equipment at all times if one wants to make use of it. In situations like this, picking up an insurance plan can Giúp to ease the tension of handling such a high-priced device.

“Having insurance on my cell phone has been awesome because once my phone fell in the toilet bowl and stopped working, and a second time it was stolen,” said Northeastern sociology major Tara Doran. “With the insurance (each time) I was able to get replacement phones of the same model.”

Convenience
In addition for use when on-the-run, another main reason people want to own a cell phone is in case of an emergency, according to a Nov. 1, 2004 Washington Post article.

“I am quite the scatterbrained fellow, and often lose my keys, etc. so when something along those lines happens, it is good to be able to call someone without the use of change, which one doesn't always have,” Yetter said.

Having a mobile phone when in a pinch or even when just simply going out can be a comforting aid, Yetter said. “What it all boils down to,” he said, is that as much as he doesn’t want to subscribe to a service he believes is a problem with America, he has to acknowledge that in many cases it is necessary to own one.

In today’s society, especially in the setting of a college campus, the need for each individual to own a cell phone has come to the point of it being personal information so closely identified with a person that it can be found as a separate field on various applications forms and profiles on internet sites. It is just simply necessary to have one these days as the pros will always outweigh the cons, said Baxter.

“You can get in touch with group members (for school projects) at anytime or call a friend when you’re just hanging around campus,” she said. “Having a cell phone is just plain very convenient."

Levin said that they just make sense the world today.

"Ten years ago, before cell phones and iPods, you would've thought someone was psychotic (for being) alone, muttering something under their breath or singing a tune," he said. "(They) just fit so well with our fast paced life and our inability to wait."
