As the concerns regarding global worming were increased, the pressure of greenhouse gas(GHG) emission reduction on mobile source was also increased. Carbon Dioxides contribute over 90% of total GHG emission and the mobile source occupies about 20% of this CO₂ emission. Therefore automotive exhaust is suspected to be one of the major reasons of the rapid increase in greenhouse effect gases in ambient air. In this study, in order to investigate CO₂ emission factor characteristics from passenger cars(PC), which is the most dominant vehicle type in Korea, 103 vehicles were tested on the chassis dynamometer. CO₂ emissions and fuel efficiency were measured. The emission factor characteristics by displacement, gross vehicle weight, vehicle speed and CVS-75/vehicle speed mode were discussed. Test modes were vehicle speed modes and CVS-75 mode that have been used to develop emission factors and to regulate for light-duty vehicle in Korea. It was found thai CO₂ emissions showed higher large displacement, heavy gross vehicle weight, low vehicle speed and CVS-75 mode than small displacement, light gross vehicle weight, high vehicle speed and vehicle speed mode, respectively. From these results, correlation between CO₂ emission and fuel efficiency was also determined. The results of this study will contribute to domestic greenhouse gas emissions calculation and making the national policy for climate change.

This study is focused on making a genuine institutional improvement from the one-sided change of the system which was implemented to guarantee student’s right to learn, and is purposed on re-align the teeth that the Article 1 of Promotion Act of School Sports(purpose) and main agents of academic sports. To accomplish this goal, the results of the study conducted on the soccer team of the middle school in ‘Y soccer specialization agency’are as follows. First, the system for guaranteeing the right to study was represented by‘unfit clothes’. Second, student athletes needed a rest. Third, main agents of school sports were worried about downgrading. Alternatives to improve this are as follows. First, we suggested rearrange of the tournament period, supplementation of e-school learning, and strict implementation of the minimum academic achievement policy system. Second, we suggested the necessity of consideration for student-athletes. Third, we suggested competitive weekend-league. Fourth, we proposed values that institutional aspects and main agents of academic sports should have.

The purpose of this study is focused on to identify the relationship between sportsmen and sports to lead to the real qualitative development of sports away from sports deviation. Thus, based on Aristotle"s theory of Hylomorphism, this study sought to re-explore the nature and meaning of sports and sportsmen by applying the concepts of matter and form, potentiality and actuality, and most appropriate matter. Hence, we suggested that why sportsman should not participate in sports deviation, what proper ethics should be held as sportsmen, and why the proper ethics should be cultivated. First, we studied the relationship between sportsmen and sports based on Aristotle"s theory of Hylomorphism. Second, we researched the potentiality and the importance of sportsmen through potentiality and actuality. Third, we emphasized that sportsmen should be a most appropriate matter to make the sports.
