PILET nr. 1 1. TEHNOÖKOLOOGIA KUI TEADUSALA MÕISTE TÄHENDUS 2. MIS ON SADAMA EESKIRI? 3. JÄÄTMEKÄITLUSE ARENGUD 1) Tehnoökoloogia on teadusala, mis uurib ja kavandab meetodeid ja meetmeid inimese elukeskkonna kaitseks ja parendamiseks ning inimühiskonna jätkusuutlikkuse tagamiseks. Tehnoökoloogia on õppeaine, mis tutvustab meetodeid ja meetmeid, mis on vajalikud inimese elukeskkonna kaitseks ja parendamiseks ning ühiskonna jätkusuutlikkuse tagamiseks. Tehnoökoloogia nimetus on tuletatud selle sisust: tehno (kr. techne tehis, kunst, meisterlikkus) + öko (oikos - kodu, kodukoht) + loogia (logos - õpetus). 2) Sadama eeskiiri on dokument,mis peab olema iga sadamal ja kus on peavad olema kirjeldatud vähemalt: 1) sadama üldandmed; 2) veesõidukite sadamasse sisenemise korraldus; 3) laevaliikluse korraldus sadama akvatooriumil; 4) veesõidukite sadamas seismise korraldus; 5) veesõidukite sadamast lahkumise korraldus; 6) o...
