집단수준에서 변혁적 리더십 및 집단 효능성과 집단성과의 관계에 관한 연구
조임현,유동근 한국경영과학회 2000 韓國經營科學會誌 Vol.25 No.1
The purpose of this paper is to investigate the relationships among transformational leadership, group-efficacy, and group performance. A total of 321 employees of a fire and marine insurance firm in Seoul anonymously completed the Multifactor Leadership Questionnare-Form V. which consists of tree factors(charisma, individualized consideration and intellectual stimulation) for transformational leadership, and two factors(contingent reward and management by exception) for transactional leadership. The sample, which largely consists of sales supervisors and salesmen, includes 41 sales office branches. The findings of the study are as follows Transformational leadership is closely associated with group-efficacy and group performance. That is, there are significant correlations between transformational factors and group-efficacy, between the factors and group performance, and between group-efficacy and group performance. A stepwise multiple regression analysis revealed that transformational leadership augmented the subordinates's extra efforts. It was also found that group-efficacy was mediating the relationship between transformational leadership and group performance. The managerial implications of these findings and future directions jof research are also discussed.

조임현 세종대학교 1982 세종대학 논문집 Vol.9 No.-
Operation Research/Management Science is both a body of knowledge and an approach for analyzing and solving management prblems. Here are several reasons why any organizations should consider the use of OR/MS. They are: (1) To minimize the effcts of surprise developments. (2) To cope with increased complexity (3) To mimimize the impact of poor decisions (4) To keep up with rapid changes (5) To avoid the limitations of intuitive reasoning. The degree of implementation of qntitative models has steadily been increasing due mainly to increased awareness regarding the actual success of tested models, better quality of the model, reduced cost of computer systems, and higher level of technical education. Decision analysis in the defense sector and private sector has made great deal of progress. The problem of implementation has recently begun to receive attention. The manager often has to consider several additional factors: political influences, labor negotiations, cost/benefit analysis, etc. Also, required core the establishment of trusting, informed relationshps with OR/MS practititioners and the interpersonal competence of the OR/MS Practitioners. The degree of successful implementation can be increased by considering the psychological and sociological factors in the design of the model. Implementation of OR/MS models can be increased by conducting extensive research into the bebavioral areas of interpersonal group, and tntergroup functioning, This assertion recognizes the importance of linking behavioral aspects of the process of management with the technical aspects of modern management science models, In general, OR/MS activities are probably still in a transitional state within their organizations and for the most part, their position is undergoing fairly steady improvement in terms of the significance, acceptance, and utilization of their outputs.

조임현,이성혜 한국생산성학회 1998 生産性論集 Vol.12 No.4
Paul Hersey and Kenneth Blanchard proposed a situational theory of leadership. According to the theory, degrees of task orientation and relationship orientation must be examined in conjunction with the dimension of follower maturity to account for leader effectiveness. The present study involved 306 salesmen and 34 sales managers, who represented 6 fire and marine insurance companies in Korea. The findings are as follows ; Situational theory of leadership was most strongly supported in the high maturity condition. Employees who have much task-relevant knowledge and commitment should require less structuring on the part of their supervisor. For low maturity employees, the theory appears to be unable to predict. Perhaps the theory needs to be rephrased to accommodate low maturity types.

조임현,임정민,남희진,전용석,Jo, Yim-Hyun,Lim, Jeong-Min,Nam, Hee-Jin,Jun, Yong-Seok 한국전기화학회 2009 한국전기화학회지 Vol.12 No.4
본 논문에서는 현재 많이 연구되고 있는 염료감응 태양전지에 대해 전기화학적 접근을 통해 설명한다. 특히, 기존 도핑 개념을 적용하는 반도체 태양전지와 다른 점을 비교 설명하고, 이론적으로 어떻게 태양전지가 형성될 수 있는지를 설명한다. 또한 염료감응 태양전지가 탄생되게 된 과정을 고찰해 본다. 이어서, 태양전지에서 많이 사용되는 전기화학적 분석법을 설명하고, 어떻게 적용될 수 있는지 임피던스 분석법을 통해 설명한다. 전기화학에서 많이 사용되는 임피던스와 순환전압전류법을 통해, 염료감응 태양전지를 이루는 주성분인 금속산화물과 염료, 전해질의 에너지준위 분석법에 대해서 간단히 소개한다. This paper describes one of the hot issues in solar cell studies, dye-sensitized solar cell. DSSC is a kind of photoelectrochemical cells. Therefore, it is quite different from the conventional solar cells which originate from pn semiconductor theory, although its mechanism can be explained with the theory. This paper describes the difference between the conventional semiconductor approaches and a newly adapted one for DSSC. Especially, electrochemical analysis methods such as electrochemical impedance analysis and cyclic voltammogram are briefly introduced, which are commonly used for DSSC analysis.

상사의 변형적-거래적 리더십과 부하의 태도 및 소진(Burnout)에 관한 연구
최가영,조임현 한국산업교육학회 1999 산업교육연구 Vol.5 No.-
본 연구는 조직내의 상사의 변형적-거래적 리더십과 부하의 추가적인 노력, 상사에 대한 만족감, 부하의 리더효율성 인식 및 부하의 소진과의 관계를 실증적으로 규명하는데 목적을 두고 이루어졌다. 서울시내 특1급 호텔의 종업원을 연구대상으로 설문조사를 실시하였다. 실증적 연구분석을 위해 상관분석과 다중회귀분석을 사용하였다. 연구결과, 변형적 리더십과 거래적 리더십의 상황적 보상요인은 부하의 3가지 태도요인(리더의 효율성에 대한 부하의 인식, 부하사원의 추가적인 노력, 부하의 리더에 대한 만족감)과 정의 상관관계를 보였으며, 거래적 리더십의 예외적 관리는 부의 상관관계를 보였다. 또 변형적 리더십과 상황적 보상은 부하의 소진을 줄여주는 것으로 나타났으며, 예외적 관리는 그 반대로 부하의 소진을 증가시키는 것으로 나타났다. 그리고 리더십 유형과 소진의 3개 하위요인(감성적 고갈, 성취감저하, 비인격화)과의 관계도 구체적으로 살펴보았다.
