Friends of mine passed the Nurse Exam. I heard a news that the English teachers(couples) who taught me speaking English just passed the nurse test in the U.S. (NCLEX-RN (National Council Licensure Examination-Registered Nurse)). I'm really happy with that and they want to visit Korea again before they are employed. Hmm. What I should prepare for their visit? Maybe I need to think about my schedule... and some budget. They might not have so much time in Korea. I think it is not bad to see them at the airport first. Then I'll take them to their hotel or so. They would like to see their colleagues. I think I can join them or have dinner together. May I bring a bottle of wine? But I want them to taste some very good Korean Food. I know some good Korean restaurant near my place and somewhere. I want to show the beautiful sky of suburb. Seoul is crowded and the sky is not so clear, the air is not so clean. Need to go to Kangwon Province or Chungchung Province. And I want to show the landscape of Seoul on top of the Seoul Tower.(Observatory.) Old Saying "How isn't it happy that old friend comes from far place." I'm really excited.

Why men seem to be not intereted in women when they grew older. Today, young men or women have many opportunities to meet and date. But when men grow older, men tend not to be interested in women so much. Is it from the decreasing stamina or health problem? Or Is it from mens' busy daily life style? Partly yes, but there is a more persuasive reason. Men have curiosity about women and sexual desire, of cource. Old men too. Sexual desire is not so much decreased if he is healthy. But the curiosity might have been filled to some degree from former experience. The real reason is... They have limited free time and don't want to invest his precious time to... uncertain relation. You know, relation between men and women is always unpredictable and it is not hard to be broken. So they want to spend his time doing more meaningful things not betraying. That's why they don't seem to be.. not interested in women, even though they are kind to women.

<Alphago vs. Lee Sedol> 4th match. Today, I was really surprised at the news that Korean professional Go player Lee Sedol won the game against Alphago. Since I didn't expect anything, but Lee's creative 78th move made Alphago get mad(?). Several moves of Alphago followed were not understandable. I mean, human wouldn't make those move because explicitly they made damage(loss). Lee grabbed the oppotunities and got the profit from Alphago's mistakes. The 78th move was very creative that there were no professional Go player who expected it. I think Alphago couldn't find the right solution to it. So Alphago made several undesirable, lossy moves. As I said before, Lee Sedol is a great Korean Go player. His Creative move leaded him to today's victory. I won't forget his smile after the match.

<Alphago vs Lee Sedol> Go play. I'm an amature go player. I'm 5th degree in Go game. Go is very old Eastern game played with black and white stones. Google's Alphago is an Artificial Intelligence specialized in Go play. Lee Sedol is the Korean professional Go champion. He is also known as one of the most creative go player. This match is very famous. Maybe everyone here should be heard of it. The day before yesterday, there was the second match between them. In the first match, Alphago won. At that time, Lee might have looked down Alphago. This time, I predicted Lee would do his best, his ability and concentration. In the beginning of the match, Lee was very serious and thought much. He experienced Alphago's ability. I felt he was doing his best. There was no mistake. Lee didn't do any mistake. I felt that Alphago was super-strong. It doesn't have any emotion. It is AI supported by 1200 CPUs and 176 GPUs. Message Passing Interface(a kind of parallel processing technic) is used to speed up calculations. This time... Lee lost again. But I think Lee is great, excellent, even honoroble. Why? Some moves made Alphago think for about 2 or 3 minutes. What if the number of CPU is 100 and GPU is 10? Then Alphago will spend 20~30minutes and it will lead Alphago to lose by timeout. And what if Alphago doesnt have much data to be trained? Can Alphago win a good professional go player again? The second match made me admire Lee Sedol. He did his best and He Is the best.

Returned from the suburb(2) Running along the beach was enjoyable. I didn't put on my swim suit but it was very good. If I hadn't had have any worries, it would have been fantastic. I prepared some food because my budget was limited. Enjoying good dishes there was... waste for me these days. Anyway, it was very good time. I took some pictures there. This weekend I will see someone who want me to consult something. He want me to help with preparing for a utility model. I had experiences and I know a patent attorney isn't needed in many cases. I want to talk about business oppotunities with him. He trust me and I trust him, too. I know these days there are not so many (good) opportunities. But we will talk and think together. Maybe we can share experiences and ideas. Thanks to the commenters and the correcters again. Thank you all. :)

Returned from the suburb(1) Yesterday, I returned from the suburb. The original plan was to go outside of Seoul and go hiking. But I changed my mind right before I left my place. I went to the bank and withdraw more money for 3 days and nights. About 300$ I spent including gasoline fee and charges for expressway. As you might know, I wrote my plan to go to the suburb onto this italki notebook. 3~4 corrections and about 10 comments attached to my post. Thank you all and God bless you all. Some of them encouraged me. Special thanks to them. I could not wrote long replies because I didn't take my PC. Only I could use my smart phone to write some comments and thanks. I went to an island about 350km apart from Seoul. JeungDo island, which is located in Jeolla Namdo. South West of South Korea. It showed very beautiful beach and I enjoyed the sea wind there, refreshed. I took my old car(more than 10 years old) to get there. You know, these days the price of gasoline is very low. There were not so many people because it was not a vacation season.

Time to go to the suburb. Today, I will go outside of Seoul, Metropolice. I will enjoy fresh air, and find peace seeing the twinkle stars. I will go hiking to a small mountain. My muscle needs exercise. The true reason I go hiking is that I have hard time these days and I want to do something harder to prove myself valualbe. My budget is about $40. Take public transportations and have lunch near the mountain. I think I will be more enjoyabout if I'm with a girl friend. I don't want to call my ex-girlfriend. That's ridiculous and I have my own pride. :( Prejudice make hard to love others. Pride make hard to be loved. I know. But this is not the case. I should have time for myself.

What do you say when a voucher is about to expired. I have a situation that a voucher for dinner is about to expired. I don't have time to go there but I don't want to throw it away. because '아깝다.' What do you say if you don't need it but you don't want to throw away? Maybe the expression would be like. 'It's ~ to throw it away. it is worth $50.'

Broken Appointment. I had an appointment with a Canadian girl in Germany Today. We made an appointment to talk in Skype. She said she wanted to practice Korean so she needed help. But she didn't appear and I tried 3 times with 5 minitues interval. There were ringing but no answer. This made me a prejudice for Canadian girl. Prejudice begins. :)
