People get age and absolutely while getting age, bodies breakdown. Nowadays people live in aging society and it means that people will hard if their bodies have problem. That's because life becomes longer than before and pain will longer as much before too. Especially joint that we usually use when we move has trouble makes more hard to elder people. In reality, joint is the most problem when we get age. Many doctors researched to treat the joint and one of those things is called cord blood stem cell which is recently the most efficient to the joint.  

  What is the cord blood stem cell and how can it treat the joint? According to life science dictionary, cord blood stem cell is after giving birth to a child, incubating by using placenta and cord blood. When this cord blood stem cell administered to patient, stem cell repeatedly divide and it makes patient's body care itself. Also, administering the cord blood stem cell protects patient's joint and non-surgical therapy so it lessen their load. Patients can feel decreased pain of joint and they can move more comfortable.

  Administering cord blood stem cell helps patients who are suffering joint problem and it also lessen side effects of surgery and more quickly finish the surgery. If people operated, although it is not big surgery many side effects and complications can develop. These points can decrease because cord blood stem cell treats with the highest suitability stem cell.

Ensuring a Sustainable Future and Factory

 Destruction of the environment is becoming more and more serious. If this destruction of the envioronment does not stop, maybe in future people can not live in the earth anymore. To prevent this happening, we should ensure a sustainable future and the most important thing is restriction of factory. Everyone knows that factory makes many trash and emit polluted air. If government restrict the factory in side of environment it will be very helpful to ensure a sustainable future. There are three ways to restrict the factory that are restricting exaggerated packaging, reusing left and wasted parts, paying a fine for polluted air. Then how can we do these ways more concretely?

 In restricting exaggerated packaging way, government should prohibit using too much air or papers to pack goods. When people buy snacks and open it, they feel embarrassed because air is more than snacks' amount. Putting a lot of air in snack needs longer packages. Also, when they open packages they have to open many boxes to see the contents. These exaggerated packagings not only irritate people but also make envirnomental problem because using many boxes and air makes factorys use a lot of  packages. To make these packages, people should cut the trees or use vinyls and plastics and these packages also going to be trash and absolutely these are not good for the environment. Totop this exaggerated packaging, government should limit amount of packages such as do not put air more than snack's amount and do not use more than one box by one article.

 The other way that reusing left and wasted parts of factory can help to reduce factory's trash. When factorys make stuffs there are many left and wasted parts and if people do not reuse them, those colud be just waste. Do not being just trash, people should reuse them and there are two ways to reuse them. First,  goods that are scratched or little broken but still it can be use, can donate to orphanage or those can be sell in flee market. Second, parts which are separated from goods such as wooden board from chair can be donated or sold to another small factory that need just wooden board. This reusing left and wasted parts can help to make more clean environment.

 The last way is that factory paying a fine for polluted air. Everyone knows that factorys emit a lot of polluted air and if government do not restrict it than factorys emit polluted air thougtlessly. It can be very dangerous for people, animals and plants because air is very important to live. Government sholud restrict amount of emiting polluted air and if factory exceeded limit, government take fine from the facory. If they do not want to pay, they sholud plant many trees near their factory. Also, if they break rules several times, government will put warning stickers on goods that this factory emit lots of pollluted air. These things can be irritating things to factory but if they reduce the amont of polluted air, people who will live in future can breathe better air.

 Of course there are many other things to ensure a sustainable future but factory is the main reason that ruin the environment so we should restrict it in first. If factory keep just three things exaggerated packaging, reusing left and wasted parts of factory and restricting factory's polluted air amount than people can live in better place. People who are working in factorys need clean environment to live and environment is more important than money. For future people who live in nowadays keep this environment conditions and make it more clean.

Yeonpyeonghaejeon battle

 Battle is dangerous and terrible thing especially in the ocean. In the Yeonpyeonghaejeon(연평해전)'s important element is the ocean where is near the North Korea. When battle occurs in ocean is more dangerous than in the ground also working near the North Korea is always be alert.

 Ocean is huge and no place to hide or escape so it could be more dangerous than the battle occurs in the ground. When battle occurs in the ocean helping our army is difficult because ocean is huge and people don't know exact location. In the ocean there is no place to hide or escape. People cna't hide in the ocean because they can't breathe and also escaping is difficult without boat or life jacket.

 Working near the North Korea can be dangerous so people should be in alert everytime. North Korea and South Korea's battle is not finished its just in breaking time. Actually, small battles occur with North Korea. People shoule be more alert because of near the North Korea.

 Unless these elements battles feel less urgent. Place in which ocean and near the North Korea makes battle more dangerous and looks there is no way to breakthrough. What if the place was in the ground and with another country? Do people feel more dangerous and urgent?

Profitable Geotourism

 Geotourism can give many possible effects to country. When Busan did geotourism, it activated local economy and protect culture. These effects helped Busan to become the second city of Korea.

 How did geotourism help to activate local economy? For example, it activated local market like Jagalchi market (자갈치시장). In Jagalchi market, local people sell fishery products which they caught themselves. Toursits can eat various species of fish  immediately and this helps local people. Another example is street food. Selling street food people are absolutely local people. When tourists eat and look around street food also can help to activate local economy.

 Then how did geotourism also protect local culture? If fishery market is activated, fisherman can do fishing to keep livelihood. Fishing industry culture can be protected. Then, traditional food recipe can also protect. If tourists want to eat local traditional food.

 These effects can give many possible effects to country. It can keep these things but country also always be in alert to be overheat. If these things go to overheat, it can be dangerous because it can be too commercial. If local people alert about this then geotourism can be a great opportunity to local people in many ways.
