On April 3rd, 1973, Dr. Martin Cooper who is an inventor of cell phone called to Joel and said “Joel, I call you using real cellular phone. The cell phone!” After invention of cell phones, they have advanced as a medium of sending message, taking a picture and video, commercial dealing, and tracking the location beyond just calling tool. Even today, smart phones which can be used as portable computer are invented. With the innovative invention in the field of phone, the number of people who use cell phone and smart phone is rising. Cnet, an online IT company in America, reported that Portio Research in England released the report about the percentage of cell phone users is 50 at this time and it will be 80% in 2013 on October 29th, 2008. Nate’s online article on February 9th, 2010, referred that according to The Economist, a magazine of the England, more than four thousand-million cell phones are used in the globe. This alludes that we live in the world of cell phone. The cell, smart phones which seem to give lots of convenient ways of living modern culture, however, affect the society as a bad ways because of unhealthy, information gap, and classroom environment.
First of all, a harmful effect to physical health is one of the reasons. Using cell phone causes thumb arthritis because of too much amount of sending text messages with some applications like Kakao Talk and Tic Talk which produce infinite massage. According to National Statistical Office in Korea, 40% of people send more than 1000 text messages. If people use thumb repetitive and extravagance, this motion gives pain to finger muscles and tendons. So, it causes arthritis and damage of finger joint. Thumb has the simplest exercising radius so it has bigger side effect than any other fingers. Furthermore, Jong Yun Hwang, the author of “The assesment of spatial recognition memory on mice after prenatal exposure to mobile phone wave in utero” says that electromagnetic wave of mobile is absorbed in human body and it puts up temperature of body. So, human tissues get damaged. Also, prolonged exposure to electromagnetic wave adversely affect to organisms which have rapid cells growth such as lymph, marrow, and neuron. It causes the high incidence of leukemia, testicular cancer, breast cancer, electromagnetic hypersensitivity, etc. For example, the National Cancer Center’s professor Seung-Kuan Myeung reports in “Using cell phone and dangerousness of tumor” that people who use cell phone have higher incident of tumor than people who do not use and people who use mobile more than 10 years have a thirty percent greater risk of cancer.
The second drawback is having cell phone causes information gap due to the gap between the rich and poor. In the past, cell phone is one of the ostentation tools of people’s wealth. The price of cell phone was very high about 24 million in 1990s so, there were just a few people having mobile. As time goes by mobile’s price is getting lower and it causes almost people can have cell phone. These days, however, smartphone, the advanced type of cell phone having high price, is spreading to people. It provides many information which can get from the net and book, but its price and phone charges is too high to buy and use. So many people such as lower-income group can’t buy smartphone. With booming mobile’s various information services, the new group of data neglected class turns up. According to National Information Society Agency, information gap index is 61.9% in 2009 and it rise compare with last year the reason of prevalence smartphone. Sung ill Lee, Sung Kyun Kwan University’s System Management and Engineering professor, says owing to spreading of smartphone different type of information gap appears. For instance, Pukyoung National University’s Department of Mass Communication professor Sang Ki Lee says in his report named “Cell phone’s functions and risk” that people feel the biggest burden in using mobile at financial problem. Also, the research by Albamon, portal site for students’ part time job, shows 44% of respondent can’t but smartphone because of it is too expensive. So, people who can’t buy smartphone are not able to get useful information which smartphone users can obtain. It causes the big information gap between them and it promotes an atmosphere of social disharmony.
Furthermore, the classroom environment in school is going bad with dissemination of phones especially smart phones. According to an article which was published on November 24, 2011, the number of students who records course works and sleeps in the undergraduate class tends to be rising. Even though students don’t sleep, they search the Internet by using the smart phone. These situations affect badly to students who want to study and participate in class so, the problem is serious. The students are used to enjoy online game and search the Internet. What’s worse is that some of the students use smart phone for finding out an answer of the test in the mid-term, final exam. Because of this problem, Daegu Health College in Korea set up a locker only for smart phone in each lecture room. Before the lecture is start, most of the students put their phones in the locker and they concentrate on just the lecture without doing other things. This proves that the smart phone disturb students to study and muddy the lecture environment.
The IT is developing rapidly and lots of smart applications come out day by day. The first invention of cell phone brought people to make communication much easier than past time and this changed ways to contact each other. The next invention of smart phone brings people to approach huge amount of information and media. These innovative progresses give people convenient life, but it is obvious that this development give people harm effect such as physical problem, polarization in getting information, and bad influence in lecture environment.
