This study investigated the relationship of authentic leadership(AL) with positive psychological capital(PPC) and teamwork competence(TC) and the mediation effect of PPC to facilitate theoretical and practical development of AL. For the empirical analysis, data were collected from the sample of 172 nurses working at general hospitals. Collected data were analyzed with factor analysis, correlation analysis, multiple regression analysis, mediated regression analysis using SPSS 21.0 to test the hypotheses. Results showed that the AL was positively related to the PPC as well as TC and the PPC was positively related to the TC. And further, the PPC is found as playing as a partial mediator on the relationship between the AL and the TC. These results provided the positive influence of authentic leadership on work team. Based on these results, practical implications were discussed for effectiveness of nurse organizations. Lastly, limitations were indicated and some possible directions for authentic leadership and its relationship to work team were suggested for future studies.

The aim of this article is to examine the relationships between authentic leadership and job satisfaction and to test the moderating effects of co-workers undermining on that relationship. Data were collected from 24th companies in Korea. The sample included 490 employees chosen randomly. Moderated hierarchical regression was used to examine the moderating role of co-workers undermining on the authentic leadership and job satisfaction relationship. The results show that authentic leadership is positively and significantly correlated with job satisfaction. In addition, the results of the hierarchical multiple regression analyses support the moderating effects of perceived employee co-workers undermining with regard to the relationship between authentic leadership and job satisfaction. This study contributes to suggesting the role of co-worker's undermining as a key moderator of their relationship. The theoretical as well as practical implications of the results were discussed with the suggestion for future research.

음성이란 성대내근과 성대외근의 운동에 의해 진성대에서 규칙적이고 조화로운 진동이 이루어져 나타나는 것으로, 이러한 운동 등에 이상이 생기거나 진성대에 기질적인 변화가 왔을 때 음성이 변하게 된다. 그러나 이런 환자들의 진단을 위하여 후두소견을 관찰해 보면 진성대 뿐만 아니라, 상후두에서도 여러 가지 양상의 다른 움직임을 확인할 수가 있는데, 상후두는 진성대와는 달리 특별한 자체를 움직일 만한 근육들이 발달되어 있지 않은 구조물임에도 불구하고 여러 다른 발성에 따라 다양한 움직임을 나타내게 된다. 이러한 것들은 진성대와 연결되어 있는 성대내근이나 후두의 외부에 붙어있는 성대외근의 영향에 의해 나타날 수가 있다고 생각이 되고, 이러한 것들은 일차적으로 또는 이차적으로 성대의 진동에 영향을 줄 수 있을 것으로 생각된다. 이에 저자들은 발성시 상후두의 움직임과 성대외근과의 관계를 확인하기 위하여 상후두의 움직임을 여러 가지 모양으로 만들도록 훈련한 후 스트로보스 3102;을 이용하여 상후두의 움직임을 확인하면서, 각각의 경우에 따라 근육의 수축정도를 비교할 수 있고 비침습적인 표면전극을 이용한 근전도 검사를 시행하여 이들에 관한 연구를 하였다.다.

This study compared voice range profiles (VRPs) of modal and falsetto register in 53 dysphonic and 53 non-dysphonic adult women with gliding vowel /a/'. The results shows that maximum fundamental frequency (F0_MAX), maximum intensity (I_MAX), F0 range (F0_RANGE), and intensity range (I_RANGE) are lower in the dysphonic group than in the non-dysphonic group. F0_MAX and F0_RANGE are significantly higher in falsetto register than modal register in both groups. I_MAX and I_RANGE are significantly higher in falsetto register in the non-dysphonic group, but those are not different between two registers in the dysphonic group. There was no statistically significant difference in minimum F0 (F0_MIN) and minimum intensity (I_MIN) between the two groups. Modal-falsetto register transition occurred at 378.86 Hz (F4#) in the dysphonic group and 557.79 Hz (C5#) in the non-dysphonic group, which was significantly lower in the dysphonic group. It can be seen that both modal and falsetto registers in dysphonic adult women are reduced compared to non-dysphoinc adult women, indicating that the vocal folds of dysphonic adult women are not easy to vibrate in high pitches. The results of this study would be the basic data for understanding the acoustic features of voice disorders.
