● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

Ⅰ. Introduction
1. Study background and objectives
Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% of water consumption, and 25% of wood consumption, so buildings are mainly responsible for
1. Introduction of the project
1) Purpose of project
Through the project, we want to build extensive knowledge about cruise industry and accounting analysis (common size analysis, comparative analysis, and ratio analysis). We believe that the project makes us accounting experts.
Cruise Industry has grown and continues to grow enormously in scale. It is frequently regarded as a small but sig

우리인류는 석탄으로 환산하여 매년 90조t이라고 하는 지구에 내리쬐는 태양에너지의 조금1/100,000밖에 이용하지 못한다. 지구상의 36억 인류가 1인당 1년간 25,000t이라는 석탄을 허비하고 있다. 만약 태양에너지의 1%라도 완전히 이용 가능하면 세계의 에너지 부족은 완전히 해소 할 수 있을 것
