2.아인슈타인의 업적
①특수상대성 이론(special theory ofrelativity)
마침내 1905년 A.아인슈타인은 혼미한 상태에 있던 뉴턴역학과 맥스웰의 전자기이론 사이의 모순을 근본적으로 해결하는 이론을 제창하였다. 이것이 유명한 '특수상대성 이론'인데, 이 이론은‘모든 관측자에 대하여 빛이 일정한 속

ii) Situational Favorableness
Another element of Fielder’s theory is ‘Situational Favorableness’. We thought that this is not as sufficient as past considering changes in organization nowadays. In terms of situational factor, Fiedler elaborated on this point with just three criteria, which are ‘Leader-Member Relation’, ‘Task structure’, and ‘Position power’. By comparing organi
