One day in September 2019 , when I was scheduled for a workshop at Muju , I was amazed to see a bulletin board at the Express Bus Terminal Station of No . 3 Subway . It showed how the faces of missing persons have changed to the present complexion presumed by artificial intelligence ( AI ) . Such marvelous AI technology has been provided by KIST to help these missing people to find their families . Certainly we can tell how much a long period of time changes our appearance and attitude . Yes , it is a sufficient time for a landscape to change during a decade . We usually say a forest has changed into a sea as decades have passed . * ( 위 사진 설명 ) 미아 발생 수십 년 이 지난 후 성인 얼굴 로 바뀐 것 을 보 니 뽕나무 밭 이 바다 가 되 었 다는 상전벽해 ( 桑田 碧海 ) 라는 말 이 실감 이 났 다 . KIST 에서 기술 지원 하 는 인공지능 의 힘 이 놀랍 고 그만큼 세월 이 많이 흘렀 다는 뜻 이 었 다 . The tourist bus , which was going to carry us to Muju , was funny ! It is really a moving karaoche operated by the driver " Lucky Moon ". He welcomes any kind of meetings which need the instrumental accompaniment . Our destination was Wujeong Training Center for senior citizens . It is located within the premises of the Muju Ski Resort at the foot of Mt . Deokyu - san . International Taekwondo - won is located nearby . Surely , the ski resort and the Deokyu National Park have changed a lot the landscape of Muju area . Long time ago , it was one of the remotest mountain valleys in Korea . Now , Muju County is criss - crossed by express highways to Daejeon , Jeonju , Tongyeong and Daegu . All the participants took part in the classes provided by the Korean Senior Citizens Associations ( 대한 노인회 ) , and enjoyed meals in a mini - buffet style . Really , it was not for the taste or relish of participants but for their health . We were satisfied with such catering service . In the afternoon , we enjoyed a singalong class under the direction of a beautiful recreation leader . She stressed that singing and dancing with big laghter are good for senior citizens ' health . All the audience shouted " Yes ". Next morning , I took a walk around the lake ( 설천 호수 ) which began to be decorated by changing colors of leaves . The sky was blue , and the air was brisk . I felt like to live in a counryside palace . From the practical point of view , water resources are good to make artificial snow in winter ski season . * 그림 같 은 설천 호수 앞 에서 사진 을 찍 을 수 있 었 던 것 은 일 하 는 목사 님 심효섭 과장 덕분 이 었 다 . * 리조트 곳곳 에서 는 부영 그룹 이중근 회장 의 손길 이 느껴졌 다 . After the workshop , all the participants took an individual and group pictures in a batchelor degree robe . Though I earned a Ph . D . degree in law , I was willing to take a new picture in a batchelor degree robe . It ' s because it means a significant academic achievement . Then we left the Muju resort in order to get to Seoul just before the evening rush hours . The landscape outside of the tour bus was quickly changing . Slowly moving white clouds were left behind . Four or five decades ago , there was no express highway in this area . At that time , countryside buses carried passengers on narrow and winding roads , as seen below outside the bus window . Tho ' it is unnoticed , I ' ve become olderThan the visible real world . 어느 새 산천 ( 山川 ) 보다 빨리 바뀌 어 버린 내 나이 Thank God , I ’ ve lived a life Goin ’ thru tolerable Ups and downs , and troubles . 무 탈 하 게 살아온 삶 그것 만 으로 감사 할 일
