      • J.-J. Rousseau의 자서전 서술방식에 관하여 : 언술행위 이론을 중심으로

        이신철,박종탁,양인봉 東亞大學校 大學院 1990 大學院論文集 Vol.15 No.-

        En nous situant au discours vu dans la perspective de l'ennonciation, nous nous proposons, dans notre etude, d'analyser les quelques phrases ou le sujet evoque sa naissance et les relations qu'elle fait entre lui et ses parents. Pour cela, nous nous servons volontiers de procedures linguistiques qui dependent de la notion d'enonciation. A travers la tension entre les protagonistes, telle qu'au moment de l'ecriture le narrateur la restitue, nous pouvons constater que l'ambivalance du pere se refletent dans la double attitude de son fils : au-dela de la tendresse filiale apparaissent l'accusation et la haine, c'est ce qui nous amene donc a croire que c'est le d'esir inconscient du narrateur qui a distribue les roles a l'un rt a l'autre. en nous referant a l'opposition entre temps histor que et temps du discours, nous constatons aussi que le narrateur rapporte un enenement historique, mais en realite cette objectivite n'est qu' apparente. ciest parce que l'evocation subite de la mort de son pere revele la vengeance secrete du narrateur. La conclusions que nous pouvons tirer de notre etude, c'est que notre etude n'est qu'une approche pour atteindre les traces du sujet inconscient qui affleure dans les textes autobiographiques.

      • 변혁적 리더쉽에 관한 연구

        오종석,이용탁 釜山大學校 商科大學 1996 釜山商大論集 Vol.67 No.-

        Transformational leadership is a well-known and widely researched topic in a variety of management literatures. Bass(1985) argued to specify the distinction between transactional leaders who attempt to satisfy current needs of followers by focusing attention on exchanges and transformational leaders who attempt to raise the needs of followers and promote dramatic changes of individuals, groups, and organizations. A transactional exchanges of reward with subordinates for the services they lender limits how much effort will be forth coming from the subordinates, how satisfied subordinates will be with the arrangements, and how effectively they will contribute to reaching the organization's goals. In contrast, the transformational leader articulates a realistic vision of the future that can be shared, stimulates subordinates intellectually, and pays attention to the differences among the subordinates. The purpose of this study is to find out most suitable leadership style for Korean companies based on the transformational leadership that Bernard M. Bass proposed, and to investigate the primary impact of leadership style on the outcomes of leadership(subordinates' extra effort, satisfaction with the leader, effectiveness of the leader) to his/her supervisors, as well as the differential effect of leadership style-transformational and transactional leadership - by mediating variables such as leader's age, position, education, division area. Data were gathered from mail questionnaire conducted in metropolitan cities in Korea, A total of 522 usable questionnaires were collected from employees at 16 manufacturing firms. Independent and dependent variables have been evaluated by Cronbach Alpha for reliability. The result of the empirical analysis are as follows: First, transformational and transactional leadership have the differential effect on the outcomes of leadership by leader's by leader's age, education, position, division areas. Second, the higher transformational factor is, the higher outcomes of leadership. Third, it was verified that transformational leadership is more effective than transactional leadership to leadership outcomes. In conclusion, transformational leadership is expected to enhance the overall leadership effectiveness, such as subordinates' extra effort, satisfaction with the leader, effectiveness of the leader. Therefore, it is imperative that organizations must develop transformational leadership.

        Relationship between piezoelectric properties of ceramics and output performance of 33-mode piezoelectric energy harvesters

        Lee, Tae-Gon,Lee, Ho-Jun,Kim, Sun-Woo,Kim, Dae-Hyeon,Lee, Ku-Tak,Kang, Chong-Yun,Kim, Miso,Nahm, Sahn Institute of Physics Publishing 2018 Smart materials & structures Vol.27 No.11

        <P>Ring-type 33-mode piezoelectric energy harvesters (PEHs) were fabricated using Pb(Zr,Ti)O<SUB>3</SUB>- and (Na,K)NbO<SUB>3</SUB>-based piezoelectric ceramics. The relationship between the output performance of the PEH and the piezoelectric properties of the ceramics was investigated. Ring-type PEHs were selected for this investigation because they can be mounted on a specimen holder at the same position, ensuring structurally reliable output performance. The <img ALIGN='MIDDLE' ALT='${{{k}_{{eff}^{}}}^{2}}^{}$' SRC='http://ej.iop.org/images/0964-1726/27/11/115027/smsaae6a6ieqn1.gif'/>?×?<I>Q</I> <SUB> <I>m</I> </SUB>/<img ALIGN='MIDDLE' ALT='${{s}^{E}}_{33}$' SRC='http://ej.iop.org/images/0964-1726/27/11/115027/smsaae6a6ieqn2.gif'/> value, which was reported as a figure of merit (FOM) of the PEH under resonance condition, could not adequately explain the output performances of the 33-mode PEH with a specimen holder much larger than the size of the specimen. The <I>d</I> <SUB>33</SUB>?×?<I>g</I> <SUB>33</SUB> value, which is a FOM derived from the theoretical output power of the 33-mode PEH, can explain the variation of the output power of the 33-mode PEH with a large specimen holder. However, since the variation of the output power was more accurately explained by the <I>d</I> <SUB>33</SUB>?×?<I>g</I> <SUB>33</SUB>?×?<img ALIGN='MIDDLE' ALT='${{k}_{eff}}^{2}$' SRC='http://ej.iop.org/images/0964-1726/27/11/115027/smsaae6a6ieqn3.gif'/> value, this was suggested as a new FOM of the output power of the ring-type 33-mode PEH with a large specimen holder.</P>

        Simplified Synthetic Testing Facility with Modified TRV Circuit

        Chong, Jin-Kyo,Lee, Kyung Seob,Lee, Chang-Hoon,Kim, Gyu-Tak The Korean Institute of Electrical Engineers 2018 Journal of Electrical Engineering & Technology Vol.13 No.2

        In order to develop a gas circuit breaker (GCB), the breaking performance of the short line fault (SLF) should be prioritized over that of the breaker terminal fault (BTF). In brief, it is necessary to evaluate the thermal characteristics of the insulating gas that is filled in a GCB. In the process of developing a GCB, many companies use the simplified synthetic testing facility (SSTF).In order to evaluate the SLF breaking performance of a GCB with a long minimum arcing time, a modifications to the conventional SSTF was proposed. In this study, we developed the SSTF with a modified transient recovery voltage circuit. The performance of the newly developed SSTF was verified by an $L_{90}$ breaking performance test on a rating combination of 170 kV, 50 kA, and 60 Hz.

        대퇴경부 골절에서 다발성 핀고정술

        유총일(Chong Il Yoo),서근택(Kuen Tak Suh),이택건(Taek Geon Lee) 대한골절학회 1997 대한골절학회지 Vol.10 No.4

        The incidence of femoral neck fracture has steadily increased with lengthening of the average life span. The end results of treatment have been improving with the development of internal fixation devices. However, the anatomic characteristics of femoral neck has made the complications of nonunion and avascular necrosis as a common result. Authors analysed 47 patients, with over 2 years follow-up on an average, who were more than twenty years old and treated with multiple Knowles pins or cannulated screws during the period from February 1988 to February 1994. Following results were obtained. 1. Among 47 patients, 23 cases(49%) were male and 24 cases(51%) were female. The highest incidence was found in the sixth decade. 2. The most common cause of femoral neck fracture was slip down (55%). 3. According to the Garden's 14) classification, the displaced fracture (Garden stage III and IV) was more common (68%), and according to the anatomic classification, transcervical type was the most common (40%). 4. Among 47 patients, there were 1 case of nonunion(7%) and 2 cases of avascular necrosis of femoral head(13%) in the nondisplaced fractures(15 cases), compared to 6 cases of nonunion(19%) and 8 cases of avascular necrosis of femoral head(25%) in the displaced fractures(32 cases). There were 4 cases of nonunion(15%) and 5 cases of avascular necrosis of femoral head(19%) among the 26 patients treated with multiple Knowles pins, compared to 3 cases of nonunion(I4 %) and 5 cases of avascular necrosis of femoral head(28%) among the 21 patients treated with cannulated screws. 3 cases of nonunion(10%) and 4 cases of avascular necrosis of femoral head(13%) were developed among 30 cases in which acceptable reduction was achieved after closed reduction. 4 cases of nonunion(24%) and 6 cases of avascular necrosis of femoral head(35%) were developed among 17 cases in which poor reduction was achieved. I 1 cases(42%) were complicated among 26 cases below Singh index grade 3 and 6 cases(29%) were complicated among 21 cases above Singh index grade 4. 5. Factors that may affect the success of treatment in femoral neck fracture are not the type of internal fixation device used, but rather anatomic site of fracture, the degree of displacement, degree of osteoporosis and accuracy of reduction.
