  • Recently the concept of authenticity has made an issue on the study of transformational leadership. Without authenticity of leader the effect of leadership nullifies the effectiveness of leadership for the followers. This study examines convergently the effect of transformational leadership on trust, organizational devotion, and team performance with the moderating effect of authenticity focusing 232 hotel team members in Busan using structural equation model. The results are as follows: First, transformational leadership has shown significantly effective toward trust and organizational devotion. Second, trust toward team leader has shown significantly effective toward team performance, while devotion has not shown dignificantly effective. Third, authenticity has shown significantly effective for moderating effect between leadership and trust, but not effective between leadership and devotion. This paper make significant contribution by testing the concept of authenticity.

  • This study empirically investigated the relationship between workers' safety behavior and safety leadership, trust in leader, workers' involvement, and safety knowledge in the enterprise, and analyzed the role of the factors to identify and analyze factors that enhance workers' safety behavior that contribute to the prevention of major accidents in the enterprise. When industrial accidents occur, companies have to bear huge loss costs due to direct costs of compensating the victims and indirect costs such as human loss, material loss, production loss, and time loss. Based on the results of previous studies, this study investigated the effects of managerial safety leadership and workers' trust in leader on safety behavior through the mediation of workers' involvement and safety knowledge among production, technical, and labor workers in the manufacturing industry. Statistical analysis was conducted on 271 manufacturing workers using SPSS and PLS. The results showed that safety leadership and trust in leader can lead to workers' involvement and have a positive effect on workers' safety knowledge acquisition, which can lead to workers' safety behavior.

  • Reliable Multi-Reader RFID identification is one of issues in Multi-Reader RFID realization program in recent. And the Multi-Reader RFID reader has difficulty to obtain reliable data in data capture layer. The reason is that unreliable readings such as a false positive reading and a false negative reading and missed readings can happen by reader collision problems, noise, or the mobility of tagged objects. We introduce performance metrics to solve these reader problems. We propose three solutions the Minimum Overlapped Read Zone (MORZ) with Received Signal Strength Indicator (RSSI), the Spatial-Temporal Division Access (STDA) method, and double bigger size of tags attached on the object. To show the improvement of the proposed methods, we calculate tag's successful read rates in a smart office, which consists of Multi-Reader RFID systems.

  • 멀티캐스트 서비스는 한 단말이 수신 그를 내의 여러 단말들에게 같은 내용의 데이터 패킷을 전송하는 방법이다. 본 논문에서는 단일 채널 다중 접속 무선 LAN(Wireless LAN)의 작은 셀 환경을 기반으로 효율적 인 멀티캐스트 서비스에 대한 방안을 제안한다. 이 시스템에서 이동 단말들이 동시에 하나 이상의 패킷을 전송하는 경우 패킷 충돌(collision)이 발생하여 수신단말은 정확하게 패킷을 수신할 수 업다. 그러므로 하나의 단말만이 전송을 해야 한다. 이와 같은 문제점 때문에 신뢰성 있는 멀티캐스트 서 비스를 위해서는 단일 채널 다중 접속 방법을 그리고 무선 링크의 높은 에러율을 극복하기 위해서는 재전송 기법(ARQ)을 고려해야 한다. 제안하는 MLBP(modified Leader-Based Protocol)는 멀티캐스트 그룹 내에서 리더(leader)를 선정하고 이 리더가 송신단말에게 피드백 정보를 대표로 전송하는 역할을 수행한다. 신뢰성 확보를 위해서는 에러가 있는 패킷을 리더 외의 단말들이 수신 했을 경우에 재전송을 유도하기 위해 리더는 긍정응답(ACK) 패킷을 전송하지 않고 침묵한다. 리더 외의 단말이 에러가 있는 패킷을 수신했을 경우 각 단말들은 지체 없이 부정 응답(NAK)을 전송하여 이를 수신하는 단말에서 패킷 충돌을 유발시키고 재전송을 유도한다. 기존의 지연응답(delayed feedback) 방법과 확률적 방법을 사용한 기법들을 분석하여 측정 한 성능을 비교한 결과 제안하는 mLBP이 다른 두 기 법보다 우수한 성능을 나타냄을 보인다.

  • UHF RFID 시스템에서는 출력제한의 엄격히 규제됨에 따라 리더의 출력신호에 의존하는 패시브 태그의 후방산란(Backscattering)되는 신호는 매우 낮은 전력을 가진 미약한 신호가 되어 왜곡과 잡음의 영향을 크게 받는다. 이러한 문제는 신호검출을 어렵게 만들고 이를 개선하기 위하여 리더의 시스템은 복잡해지고 있다. 또한 현장에서 신호 검출을 위하여 근접거리에 리더를 설치하거나 협소한 공간에 다수의 리더를 설치하여 신호 검출을 하고 있다. 이러한 설치 방법은 사고의 위험이나 리더 간의 간섭에 따른 신호 검출을 더욱 어렵게 하고 있다. 본 논문에서는 태그의 패키징과 리더 안테나의 개선을 통한 태그의 인식거리 개선을 통해 신호검출의 신뢰성을 확보하는 방안에 대해서 제안하고자 한다.

  • This study analyzed the effect of Servant Leadership on leader trust and job engagement for the lower-level leader in airline crew occupations with the aim of identifying the possibility of establishing the theoretical framework of Servant Leadership in the service industry. As a result of the regression analysis, it was found that the social learning dimension of Servant Leadership has greater influence than the social exchange dimension on the leader trust, while the influence on job engagement is the opposite. The results of this analysis can be interpreted that trying to learn the words and actions of the Servant Leader is more effective in further consolidating the trust of the subordinates in the leader. On the other hand, the Servant Leader's words and actions for social exchange are inferred to have more influence on the job engagement. This study is targeted at air transport services, exposing limitations to the generalization of research results. Throughout leadership research and organizational research, including Servant leadership, further studies applying the social learning theory and social exchange theory presented in this paper are expected to produce theoretical results that will lead to the emergence of a new framework for research analysis.

  • The purpose of this study is to suggest a customized servant leadership by exploring the effects of stewardship and community building factors on the subordinates' trust in leader of lower hierarchy and their job engagement. Regression analysis showed that stewardship is higher than community building in terms of its influence on job engagement, while community building outstrips stewardship in terms of trust in leader. Specifically, two items of stewardship factor - valuing the opinions of the subordinates in decision-making, and sacrificing without giving priority to the leader's self-interest - influenced the subordinates' trust in their leader. Of the items in community building, cooperating rather than competition, abiding by the principles in performing the work, the leader's not seeking recognition or compensation, and giving the subordinates the necessary authority to perform their work put impacts on the subordinates' trust in the leader, as well. As for job engagement, helping subordinates grow and develop, and, if necessary, taking the risk of challenging the job have a significant impact. Among the items of community building, it was found that the leader's not seeking recognition or compensation, and keeping the principles strictly in performing her duties promote job engagement. Based on these results, we propose to managers of human resources department the selection and training of tailored talents to meet the environmental characteristics of each organization, while avoiding programs for hiring and training personnel equipped with the uniform qualities of servant leadership.

  • The purpose of this study was to investigate the effect of ethical leadership on employees' behaviors (deviant behavior and personal initiative) and to explore the moderating roles of self-efficacy and trust in leader in the relationship between ethical leadership and employees' behaviors. This study developed four hypotheses and tested them using regression and hierarchical regression analyses. The results showed that the negative relationship between ethical leadership and deviant behavior and the positive relationship between ethical leadership and personal initiative were statistically supported. And this study found that self-efficacy and trust in leader played moderating roles in the relationship between ethical leadership and employees' behaviors. Based on the findings of the study, this study presented managerial implications and suggestions for future studies.

  • Purpose: This study was done to examine the effects of nurses' perception of servant leadership on leader effectiveness, satisfaction and promoting additional effort. The focus was the mediating effects of leader trust and value congruence. Methods: Data were collected from 361 RN-BSN students and nurses participating in nationally attended in-service training programs. Data were analyzed using descriptive statistics and structural analysis with SPSS 17.0 windows program and Amos 7.0. Results: Direct effects of nurses' perception of servant leadership were negative, but mediating effects of trust and value congruency were positively correlated with leader effectiveness, satisfaction and additional effort, that is servant leadership should be effective through mediating factors. Conclusion: The study results indicate that if the middle managers of nurses can build leader trust and value congruency between nurses through servant leadership, leader effectiveness, satisfaction and additional effort on the part of the nurses could result in a positive change in the long term.
