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.

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.

Purpose: The purpose of this study was to investigate effects of nurse managers' conflict management styles on nurses' levels of leader trust and organizational commitment. Methods: For this study, a descriptive survey design was used. The participants were 165 nurses who had worked more than 1 year in a university hospital. Data were collected from September 1 to September 10, 2016, using a self-report questionnaire. The collected data were analyzed using descriptive statistics, t-tests, ANOVA, Scheffe's tests, Pearson's correlation coefficients, and multiple regression analysis. Results: Among the nurse managers' conflict management styles, the problem-solving style was positively correlated with both leader trust and organizational commitment. Concession-avoiding and control-leading styles were negatively correlated with both variables. Furthermore, the problem-solving style was found to have significant influence on both leader trust and organizational commitment. Conclusion: In order to more actively cope with conflict situations occurring in the nursing work environment, nursing managers need to exhibit more effective attitudes of conflict management. This study suggests that the problem-solving style is a desirable conflict management style in terms of increasing leader trust and organizational commitment.

The purposes of this research are to examine the effect of humor sense of leader on innovative behavior and to examine the moderating effects of empowerment on the relationship between humor sense of leader and innovative behavior. For these purposes, literature review and survey research were conducted. The 350 questionnaires were sent to the 10 manufactural firms in the Pusan and Kyungsang Nam-Do region for empirical analysis. Total 276 usable responses were collected(effective response rate : 78.86%). The major findings of the empirical research are as follows ; First, generation of humor, use of humor, attitude of humor and evaluation of humor which are composed factors of humor sense of leader have positive influence innovative behavior. Second, composed factors of humor sense of leader have differential influence on innovative behavior by empowerment. In conclusion, humor sense of leader is expected to improve innovative behavior which is individual behavior in an organization. Therefore, managers have to develop innovative behavior by exhibiting humor sense, considering empowerment.

The current study aims to address the relationships among conflict, person-organization fit, and workers' turnover intention. Specifically, it aims to examine whether person-organization fit mediates the relationship between conflict in team and turnover intention, also trust in leader moderates the relationship between person-organization fit and turnover intention. The empirical analysis shows that conflict is positively associated with turnover intention and have a negative impact on objective-value fit. The relationship between conflict and turnover intention is mediated by the person-organization fit. Trust in leader moderates the relationship between person-organization fit and turnover intention. The findings address the issue in terms of the mechanisms between conflict-turnover intention and the importance of trust in leader for an effective management of conflict in work teams.

리더의 리더십이 팀 또는 조직의 효과성에 기여하기 위해서는 리더의 영향력을 구성원들이 수용하고 목표달성을 위해 노력하도록 구성원들을 동기부여시켜야 한다. 그런데, 리더의 영향력을 수용하고 추종하는데 구성원들간에 공유되어 있는 리더에 대한 표상에 리더가 일치하여야 한다. 이상적 리더에 대한 공유된 표상에는 그 사회문화에서 지배적인 가치규범이 중요한 역할을 하게 된다. 본 연구는 이러한 가치의 역할이 중요하다는 인식에 착안하여 한국인의 사고와 행동방식에 지대한 영향을 미쳐온 전통적인 유교적 가치에서 가정하고 있는 이상적인 인간상으로서의 군자를 현대 경영조직상황하에서 리더십의 관점에서 살펴볼 것을 제안한다. 이를 위해 사서(四書)-논어, 맹자, 중용, 대학에서 제시된 군자의 성격 또는 행동적 특징들을 내용분석하여 리더십 구조를 정의내리고 이를 측정할 수 있는 설문문장을 개발하였다. 그 결과, 군자리더십은 자기계발(思學), 인간존중(忠恕), 예절중시(禮), 공정함(義), 사람 관리의 5개 요인구조를 가지고 있음을 발견하였다. 추후 연구에서는 개발된 설문문항의 신뢰성과 타당성을 검증하고, 본 연구에서 개발한 군자리더십이 실제 경영조직에서 경영자의 리더십효과성을 잘 설명해주는 변별력 있는 개념인지 검증하는 노력이 필요하다. 이는 서양의 보편적으로 효과적인 리더십 유형, 예를 들면, 변혁적 리더십 유형과 같은 경쟁모형의 도입을 통해 보다 더욱 생동감 있는 측정이 가능할 것이다. 아울러 유교적 가치와 현대적 가치로 대변되는 합리성에 기반한 서구의 가치가 군자리더십과 어떤 관계를 가지고 있는 지 살펴 볼 필요가 있다.

This study attempted to show the importance of trust in a leader by empirically analyzing the relationship between transformational and transactional leadership, organizational effectiveness and trust in a leader. Four hypotheses were formulated and a survey was conducted to examine employees working in hotels in order to verify the hypotheses. Based on the data, leadership, trust in a leader, its relation with organizational effectiveness, and the mediating role of trust in a leader of a hotel were analyzed. The results showed that trust affects the partial mediating or the perfect mediating between leadership and organizational effectiveness. It is hoped that the result of this study will contribute to the development of leadership in the hotel industries in the future.

RFID 시스템에서 소형화 추세 및 배터리 사용에 따라 태그 및 리더의 전송 전력을 최소화할 수 있는 저전력 설계가 반드시 필요하다. 또한 리더와 Tag는 무선으로 통신을 수행하며, 동시에 Tag는 이동성을 가지므로 에러율이 유선방식에 비해 상당히 높다. 그러나 현재 ISO표준에서는 에러발생시 MAC계층에서 단지 CRC체크 후 재전송을 하는 방식으로 에너지 효율성 및 전송효율이 떨어진다. 본 논문에서는 이 같은 문제를 해결하기 위해서 유통 물류 등에 사용되는 900MHz대역의 RFID시스템에서 에너지 소모 최소화와 신뢰성을 보장할 수 있는 방법으로 Hybrid ARQ를 제안한다. 기존의 Hybrid ARQ를 개선시켜 에너지 효율성을 고려한 최적패킷 길이를 사용하고, 에너지 소모가 적은 BCH Code를 채택한다. 성능 분석 및 시뮬레이션 결과, 제안하는 Hybrid ARQ 방식이 기존의 전송방식보다 에너지 효율성 및 신뢰성을 향상시킴을 보여준다.
