My 7 Bio-Wonders!(2) <4> Nowadays, I lose my hairs much than any other season. I worried about that, so I got hair cut and scalp massage but it was no use :'( It turned out my losing hairs are due to the season. Because of the cold and dry weather, my scalps became weak and my body feels stress during adaption to cold. Now I can stop worrying about my hair! <http://imnews.imbc.com/replay/nwtoday/article/3375794_5782.html> <5> In 2009, when I was 16, novel swine-origin influenza A (H1N1) hit all around the world. H1N1, the new virus that was born by mutation of influenza type A virus, is the respiratory disease that infects worldwide people. Many schools closed for several days because of the infection of H1N1 from students to students. (My school also closed for 2-3 days at October!) Until the vaccination of H1N1 was developed on November, 2009, H1N1 made the world be trembled of infection and even death by this disease. <http://science.dongascience.com/articleviews/special-view?acIdx=9026&acCode=1&year=2013> <6> Sleep is one of the most important factors for people to live. There is study that we remove the toxic substances during sleep. However, I can’t sleep enough because of early classes, assignments and exam. I should sleep enough much to live vigorously after end of this semester. http://science.dongascience.com/articleviews/article-view?acIdx=12724&acCode=4&year=2013&month=12&page=1 <7> Students often drink energy drink when they have to stay up all night because of exam, assignments, etc. Energy drink is a beverage which contains high concentration of caffeine and taurine. People only drink energy drink with thinking caffeine make them stay up. However, there is a research that energy drinks make contraction of heart increase. It needs more study to reveal about long-term effects of energy drink to our heart. <http://www.sciencetimes.co.kr/article.do?todo=view&pageno=1&searchatclass2=117&atidx=73003&backList=list&seriesidx=list&menuclassidx=117&%BA%B8%B0%C7%A1%A4%C0%C7%C7%D0=%BA%B8%B0%C7%A1%A4%C0%C7%C7%D0>

My 7 Bio-Wonders! (1) Nice to meet you. My name is Jeong ju young. I hope to major Food-engineering and work for foreign cosmetics company such as LANCOME, Estee Lauder, etc. To do that, I have to get high scores and study English harder. Anyway, it's honor to take this class with you by Professor Park. <1> A few months ago, during cleaning the closet with my mom, we found a very small cloth. That was my 배냇저고리 which I wore when I was baby. It was so small and I can't imagine that I wore this tiny cloth. (Its size was just big as my face!) At that time, I'm astonished and feel how much I grow for 20 years. <2> Many travelers eat airline meals with no curious, and so did I. But there are many scientific principles on cooking airline meals. During flight, people are at extremely high place, so the pressure is lower than 1atm and very dry in airplane. Therefore, they decrease the spaces that contact with air to control water loss. Also, people's sense of taste become dull in sky, they make the meals more salty. And the meals aren't boiled because the water boils at lower than 100 Celsius degree. I am so surprised at these many principles! <http://news.naver.com/main/hotissue/read.nhn?mid=hot&sid1=105&cid=926419&iid=774742&oid=055&aid=0000261697&ptype=021> <3> A few days ago, I watched the movie, 'The Island'. This is the movie about biotechnology and human cloning. In the movie, rich people make a clone of themselves to prepare for their disease or artificial insemination (인공수정) and clones are alive and can think and feel. And I found an article about stem cells and the possibility of human cloning. <http://www.econovill.com/archives/131960>

Problem-Solution Essay The Part-Time Job of Minors While the percentage of doing part-time job of high school students is increasing every year, the legal system in place to protect student is too weak. Because of weak legal system of child labor laws, bosses are able to make many illegal and immoral behaviors to minors. Many bosses do not pay minors enough. For example, although the minimum wage of Korea is 4860 won for an hour, most minors get 3000-4000 won for an hour. Also, minors are more likely to be exposed to dangers. For instance, there are many sexual harassments done to girls by employer of customers at gas station, café or restaurant and boys who are not qualified to drive have high possibility of being a car accident during delivering. To solve these problems, the government should enforce the legal system to protect working minors by activating the report center of violating labor laws. If employer does not pay minors proper wage, they may accuse the employer for violations of child labor laws easily. Then employer has to pay a fine or be ordered to suspend business. Also, there has to be a law that minors should not work which is beyond their means of students. Minors should not do inappropriate work for them such as delivering by motorcycle or serving alcohol at bar.
