1980년대부터 많은 관심을 가져온 변혁적 리더십이 조직구성원의 조직몰입에 어떠한 영향을 미치는지, 또한 바람직한 목표를 달성할 수 있는데 어떠한 효과가 나타나는지에 대한 체계적인 검토가 요구된다. 이점에서 본 연구는 변혁적 리더십이 조직구성원이 의 조직몰입에 어떠한 관계가 있는지를 분석하고자 했다. 본 연구는 표본집단으로 공기업인 한국담배인삼공사, 한국전력공사, 한국통신공사 등을 선택하였으며, 이들 공기업에 근무하는 직원 500명(유효표본 396명)을 대상으로 설문조사를 실시하였다. 가설검정 결과에 비추어 본다면, 지적자극형 리더십이 조직구성원의 정서적 몰입에 가장 긍정적인 영향을 미치는 것으로 이해할 수 있었다. 상관의 지적자극 리더십이 조직구성원의 정서적 몰입에 긍정적인 자극을 준다는 점에서 상관의 리더십에 대한 관리체계에 대한 관심을 가지는 것이 중요하다. 지적자극형 리더십을 제고하기 위해 조직구성원들이 보다 많이 의사결정에 참여하는 체계와 조직구성원에 대한 다양한 평가체계를 시도할 필요가 있다고 본다. 또한 조직의 건강성(health)과 혁신방안을 도입함에 있어 목표관리제(Management by Objective)를 도입하는 방안도 고려할 수 있을 것이며, 나아가 능동적인 근무의욕을 불러일으키기 위해서 조직구성원간에 경쟁주의를 도입하는 것도 고려해 볼 수 있을 것이다. The world of leadership is undergoing a revolution. Thus, leadership studies are an emerging discipline and the concept of leadership will continue to evolve. Also, leadership studies are complex and elusive problem largely because the nature of leadership itself is complex. That is, leadership is a complex process that results from the interaction among a leader, followers, and the situation. Especially, this study is suggested leadership involves the influence of people to bring about change toward a desirable future. Under the definition of leadership, this study has two research problems: Firstly, what kind of people can lead an organization through major changes? In this question, this study has analyzed two types of leadership, such as transactional leadership and transformational leadership. Transactional leadership is a transaction or exchange process between leaders and followers. Thus transactional leaders focus on the present and excel at keeping an organization running smoothly and efficiently. On the other hand, transformational leaders have the ability to lead changes in the organization's vision, strategy, and culture as well as promote innovation in products and technologies. Also, transformational leadership inspires followers to go beyond their own self-interests for the good of the group. Effective leaders exhibit both transactional and transformational leadership patterns, though in different amounts. Secondly, what has the relationship between two types of leadership and organizational commitment for employees? Due to this question, four research hypothesis are presented as followings.

Asbestos exposure is responsible for the majority of cases of malignant mesothelioma. Although a few cases of malignant mesothelioma were reported in Korea, there has not been any proved cases associated with long - term occupational asbestos exposure. We report a case of diffuse malignant pleural mesothelioma in a patient with a 19 year occupation- al asbestos exposure.

A PSD which cooperates with train door provides safety and convenience for passengers. In order to cooperate with train door, the PSD should interface between the PSD control system and the control units of train door. This interface is generally performed in signaling system(ATC/ATO), however, the lines which don"t have the interface functionality in the signaling system, it is required to have additional "PSD inter face system" to communicate between train and PSD. In this paper, we propose a safe PSD interface methodology by discussing interlocked control between train door and PSD, recognition of accuracy stop point, troubleshooting logic and log of troubles and driver panel which are adopted in Inchon line1.

A Diode bridge rectifier and a phase-controlled thyristor bridge rectifier generate harmonics in power system. Nowadays, power factor and harmonics are important performance in electrical equipment for railway vehicle. Many researchers have been trying to improve the power factor and ac-side harmonics. Therefore the PWM converter has been used to operate at unity power factor and to reduce ac-side current harmonics. This paper proposes the synchronization loop by vector product in single-phase PWM converter. The proposed control method can realize the sinusolidal input current waveform and the effective unity power factor. The validity of the proposed control method is verified through the experimental result.
