People should set on vibrate or turn off their cellular phones in public areas. Using cellular phones in public areas can make other people uncomfortable. Maybe, you have experienced the bell rings or melodies of cellular phones in public areas. How did you feel? Was that comfortable for you? Furthermore, using cellular phones in a plane, hospital, or while driving can cause a serious accident. Misuse of cellular phones can even cause other people's death. Therefore, I think that the Korean Government should pass laws to forbid misuse of cellular phones, and the users should change their attitude.
　　　 A few weeks ago, I read an article in a newspaper that said there are over twelve million people using cellular phones in Korea. That's at least 20 percent of the people of our nation. If we consider only the number of adults, the percentage is even higher. Korea is one of the nations in which many people use cellular phones. In addition, this is much higher than several years before. Increase of the use of cellular phones causes lots of problems. The users overlook the harm of the cellular phones. Lots of people carelessly use their cellular phones in dangerous areas. For example, electronic waves can cause significant problems to the electronic machines in airplanes and hospitals. Furthermore, using cellular phones while driving a car can lead the users to cause traffic accidents. It can be a serious social problem that directly influences people's lives. The Korean Government ought to make laws to forbid using cellular phones in areas where the cellular phones can cause accidents.
　　　 Besides the case of dangerous areas, there are lots of misuses of cellular phones in public areas. At a recent concert of Jung Kyoung-hwa, a famous cellist, for instance, several cellular phones rang. This was reported on the MBC news, and it made people recognize it as a significant problem. Frankly, before this event, people didn't recognize the rings as a problem. Some of the thoughtless users of cellular phones have thought about cellular phone only as an article of luxury. Therefore, they have felt pride whenever their cellular phones rang. In my case, I have experienced cellular phones ringing in theaters, libraries, restaurants, etc. I couldn't concentrate and I thought that the users should change their minds. The users of cellular phones should set their cellular phones on vibrate or turn them off before they enter such places. This is good manners toward other people.
　　　 The Korean Government has announced that it will make laws to forbid misusing cellular phones in dangerous areas next year, in 1999. Certainly, there must be more campaigns to reduce the misuse of cellular phones in public areas. I think that these attitudes of our government are good to protect people from dangerous situations and for the public benefit. The laws and campaigns can help to reduce the misusing, but there must be a change in the users' attitudes first. If people thought about other people's comfort first, the problems would be reduced easily.
　　　 You, the users of cellular phones, should recognize that the misuse of cellular phones is bad manners. By changing your minds you can increase other people's comfort. I read in a newspaper article a few days ago that the noise of a cellular phone bell is as loud as a noise made by a machine. This is clearly a kind of noise polution. Think about this situation. If someone's cellular phone rings next to your seat in the library, will you happy to hear it? You will be angry. Think it before you use the cellular phone:
　　　 You can't live alone. Don't think that you are special, and different from other people. Furthermore, don't forget that your comfort can be other people's discomfort.
