About
2016년 전국 학교를 조사해 보니 우레탄 트랙이 깔린 학교 64%에서 기준을 넘는 중금속이 나왔습니다. 그래서 다 걷어내고 마사토로 돌아가면 끝일 줄 알았거든요. 그런데 학교들은 오히려 다시 우레탄을 원했죠. 더 이상한 건 KS 인증 재료가 전부 기준을 지키고 있었다는 겁니다. 정부는 납이 트랙을 굳히는 현장에서 들어간 걸로 봤더라고요. 그래서 검사 대상이 재료에서 깔린 바닥으로 바뀐 과정을 담았습니다. #우레탄트랙 #학교운동장 #마사토 #중금속 #납검출 #KS인증 #현장검사 #건축공학 #신비한건축사전

Frequently asked questions
How accurate are these YouTube video analytics?
View, like, and comment counts come from YouTube's public API and refresh regularly. Growth and revenue figures are estimates built from tracked historical data, so they can differ slightly from what the creator sees privately in YouTube Studio.
What is the outlier score?
How this video's views compare to the channel's usual Shorts or long-form video. A 2x score means double the usual views for that channel, 0.5x means half.
What is engagement rate and how is it calculated?
Likes and comments per view, compared to this channel's typical engagement rate — shown as above or below what's usual for the channel.
How is the revenue estimate calculated?
It's a rough public estimate based on a $0.7–$2.0 CPM (revenue per 1,000 views) applied to view count — not actual creator earnings, which depend on ad rates, audience geography, and monetization settings YouTube doesn't expose publicly.
Is this YouTube video analytics checker free?
Yes. You get 10 free channel and video analytics lookups per rolling hour without an account — logging in, which is also free, removes that limit entirely.
