피츠버그에 여름이 왔다. 지난주까진 비와서 꽤 시원했는데, 이번주부턴 heat advisory (폭염주의) 가 권고된다.미국에서 지낸 세번의 여름동안 실내 온도가 30도가 넘으면 행동이 느려지고 멍때리는 시간이 길어지는 것 같았다. 그래서 오늘, 아침먹다 땀이 비오듯 흐르길래 꽁꽁 싸놨던 창문형 에어컨을 거실과 침실에 각각 설치했다. 침실에는 최근에 산 인버터 창문형 에어컨, 거실엔 LG 이동식 에어컨 (정속형)을 각각 설치했다. 창문을 열고 배기하는거라 플라스틱 칸막이로 배기관 주변을 엉성하게 막는 형식이다. 기밀이되도록 투명테이프를 테두리에 붙였다. 맘에 들진 않지만 한철 잘 보낼 수 있으면 되었다. 몇가지 마음에 걸리는 점:이동식 에어컨에 배수처리가 따로 밖으로 나와있지 않아 찾아보니 냉방 시 생..

This seems unfair to me since my body always requires some regular exercise for a productive life. Without it, my body's strength becomes weak which m..
Cultural connection
I have experienced an exchange student program in Singapore. It was my first experience abroad. There, I had three goals: practice English, make foreign friends, and learn any differences outside of Korea. I thoroughly followed this guideline. Although my academic achievement was pretty low, my understanding in sociology enhanced. I used to think foreigners were like aliens who were beyond my un..
