good and bad effect for using GPS

GPS is very useful tool in these days. almost 10year ago, navigation system was invented and used to find out every place. but there are some bad effect for using GPS. a few month ago, it was a problem about collecting private information from smart phone. so bad effect is that abuse this kind of information. if government or company get this information, they can pursue a person's activity and also can know where someone moves. for instance, Gaddafi was detected where he hide because he was used his phone. it's a good effect for using GPS. but if someone uses a bad way. it'll be bad for private life.

except this ways, it has lots of good effect. for example, most of people have smart phone. and we can use smart phone. when we go to some place at first time, we can use map service from smart phone. we can search a name of building or place. we also find to some thing around of me. that's good way.

so I agree to use GPS.

raining in korea

in the summer, it's been lots of rain in this year. we know that it's heavy rain every summer. but some place are over flood. so we can think why it happens every year. so we should find out solutions.

specially, it was lot of raining. weather climate is changing now. we exactly don't know how fast weather change. and it's always late to precaution about raining. because government is late to prepare and misestimate how to change weather.

so some place are over flooding every year. government don't prepare important thing.

so how can we prevent about flooding. I think first thing is that changing old pipes on underground. that's so old and not to big. but if they change big pipes, it's easy to flow water in the pipe.

and second thing is that to make reservoir nare special area. that was a good result to prevent flooding. so I recommend to 2 method. then it's happened less than before.

how to prevent sexual violence

this society is to be more violence then past. so crazy accident have often happened many times. and the crime of child is also increased. 
most of child crime is sexual violence, and we can think why it is focused on child,
I think that it's easy to make sexual violence to them. 
most of children still don't make situation of basic mental. so criminal can be violence for them. so they can do sexual violence to them.
and they can cheat children from something. if they give children a favor. like buying something. so it's easy way.
and junior high school or high school student want to get the money, at that time, most of student want to get new item. so they are try to get money from adult. so strange person can abuse this kind of way. and then they can do sexual violence.
so first thing to prevent method is the education. if teacher can educate the children about sexual violence. and what it is sexual violence. 
then they can understand what is sexual violence.
than second thing is that government have to make strong policy about sexual violence. like they can designate people who are citizen policer. and government have to strong control criminals. 
then it will not be happened more. however it's also hard to prevent all of crimes. 
all of people who are adult have to protect around of our society.

university tuition fee

i've got lot of information from the presentation. it's now hot issue. a few month ago, new mayor of seoul city was elected from seoul citizen. and he suggested new plan for university fee. tuition fee of seoul national university is going to get a half of total price. 

I think that's a good trend to change past policy. because changing university fee is now a small change, but it will bring big changes. in korea, it's normal trend to go to university. so parents should pay lot of money to university. it's a big burden. however the university have to invest something for students. but they didn't invest a lot. they just want to get more money, and then they want to built a buildings. so they think it can bring more student. 
it's wrong thinking. 

so it's a good trend to cut the tuition fee. so student who want to study hard pay just a little money. and they will right idea for university. 
when student is to be a worker of government that they can help and give them good idea.

when most of university changes their policy for tuition fee, it's more easy way to study. I hope to be changed this problem.
