Trust has been viewed from many perspectives according to their domains. This article reviewed some of many formerly suggested studies and models. And antecedents of trust, such as trustworthiness(ability, benevolence, integrity) and individual trust propensity as well as their interactions, were respectively and empirically tested in the context of Korean workplaces. Through the factor analysis of field survey(N=243), proposed conceptual independence in trustworthiness was only partially supported. Of the relationships between antecedents and trust, all components of trustworthiness were significantly sustained. While effects of individual trust propensity and its interactions with trustworthiness on trust were not found.

본 연구에서는 댐 유역의 설계홍수량을 산정할 시 발생할 수 있는 대표 매개변수의 불확실성에 대하여 분석하였다. 설계홍수량 산정 방법으로는 국내에서 가장 일반적으로 활용되고 있는 강우-유출모형 중 Clark 단위도를 활용하여 확률강우량을 동일 빈도의 홍수량으로 변환하는 방식을 적용하였다. 대상 유역으로는 수문학적 안전성평가가 수행된 국내 댐 유역 중 비교적 실측 호우사상 자료 수가 많은 3개 유역을 선정하였다. 또한 단위도 매개변수 결정 시 자료의 부족으로 최적화 매개변수에 대한 신뢰도 문제가 발생할 수 있으므로 가용 자료수가 증가함에 따른 불확실성의 영향을 분석하기 위해 대상 유역 간의 시간응답 특성을 분석하였다. 이를 통해 상사성이 있는 것으로 판단되는 유역의 호우사상 매개변수를 통합하여 무차원화된 저류상수 $K_x$를 구하였다. 이 $K_x$값을 표준정규분포로 변환하고 Monte Carlo Simulation을 통해 난수를 발생시켜 100개의 무차원 저류상수 $K_x$를 산정하였다. 이 값을 사용하여 설계홍수량을 산정하기 위한 대표 매개변수의 불확실성 분석을 실시하였다. 그 결과 상사성이 있는 것으로 판별된 유역의 호우사상을 통합하는 경우 양질의 호우사상을 다수 확보하고 있는 유역이 추가되면 홍수량 산정결과가 개선되는 것으로 나타났다.

This study tries to testify that how much knowledge sharing behavior affects organizational effectiveness and is affected by the supervisory trust empirically. The results show that the higher the supervisory trust was the higher the level of knowledge sharing behavior and ultimately, organizational effectiveness is improved. Specially, the supervisory trust affects job-related knowledge sharing behavior and knowledge sharing system behavior. The knowledge sharing culture, however, is no relation with the supervisory trust. Job-related knowledge sharing behavior influenced both job satisfaction and organizational commitment. But knowledge sharing system influenced only job satisfaction and knowledge sharing culture influenced only organization at commitment. The implication from this paper is that knowledge sharing improves the organizational effectiveness and the supervisory trust is important for knowledge sharing in R&D organization.

The main purpose of this study is to empirically examine and to develop the optimal model about an influential relationship between the types of source-based trust and knowledge sharing of local government officials. Procedural and distributive justice-based calculative trust in organization, cognition-based trust in organization, cognition-based trust in supervisor, cognition-based trust in coworkers, and emotion-based trust in coworkers were set up as independent variables of this research model, and sharing of tacit knowledge and explicit knowledge based on the knowledge content as dependent variables. The research results shows that the suitability of each model has approximate value to the required level, and that emotion-based trust in coworkers significantly affects knowledge sharing for both the individual and integrated factors in hypothetical influential relationship. This study is expected to help to enable knowledge sharing in various situations by dividing the concepts of trust that affect knowledge sharing into a few types, and deriving the influential model of knowledge sharing by types.

This study was conducted to investigate the effects of trust in supervisor, work intensity, and organizational cynicism on organizational silence of clinical nurses. Data were collected from 134 nurses in 6 hospitals in two cities in February 2018. The data were analyzed by t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and stepwise multiple regression using SPSS 25.0. There were significant correlations between trust in supervisor, work intensity and organizational silence, r=-.32(p=<.001) and r=.18(p=.043), respectively. The factors that significantly influenced organizational silence were trust in supervisor (${\beta}=-.36$, p<.001), the length of career in current hospital (over 10 years, ${\beta}=-.67$, p=.002), type of work (day only, ${\beta}=-.79$, p<.001; 3-shift, ${\beta}=-.64$, p<.001). In order to reduce clinical nurses' organizational silence, programs should be provided to increase trust in supervisor and to offer changes in work types and work intensity.

The study examined the relationship between servant leadership and organizational commitment and tested the mediating role of the organizational trust between the two variables. Measurement of servant leadership used intactly 23 items of a preceding research. Empirical analysis result can be summarized as follows. Firstly. the servant leadership has positive influence on organizational trust. Secondly. servant leadership has significant influence on affective commitment and normative commitment, but could not reach the significance level for continuance commitment. Lastly, this study was proved there was an partial mediating effect of organizational trust, between the servant leadership and affective commitment, normative commitment, but could not reach the significance level for continuance commitment. And if the organizational trust is higher, the extent of the servant leadership's influence on organizational commitment would be higher.

The purpose of this study is to examine antecedents and outcomes of trust toward supervisor in organization. The model is developed by reviewing previous research providing various perspectives. Antecedents consisted of three trustworthy behaviors - ability, benevolence, integrity - and three transformational leader behaviors - performance management, motivation, team-orientation -, and job satisfaction and organizational commitment is used outcome variables of trust. Data was collected from 206 employees in 6 organizations in broadcasting industry, using self-report questionnaire. Study finding is as following. First, trust in model was composed by 2 type - affect-based trust and cognition-based trust -, not divided in empirical analysis. Second, regression analysis for trust carry out independently, jointly with trustworthy behaviors and leadership behaviors. In antecedents of trust trustworthy behaviors, ability and benevolence has positive effects to trust, integrity has negative relationship with trust. It was high correlation between trustworthy behavior and leadership behavior. Especially, it has highly correlate(correlation efficient 0.69) between ability and team-orientation that influences trust strongly. Third, trust was not significant relationship with individual variables such as age, period with supervisor. Only, it found significant gap in variables and found out different relationship between variables among organizations distinctly. Fourth, job satisfaction and organizational commitment was positive influenced by trust and found out strong relationship between trust and organizational commitment.

The objective of this study is to provide the information on the small-scale model mix proportion when the behavior of prototype concrete pavement is studied through small-scale model experiments. However it is difficult to obtain a model material to simulate the prototype concrete by scaling the individual components according to the laws of similitude. In this paper, the stress-strain behavior in uniaxial compression is used as a means to correlate material similitude between the prototype and the model concrete. Based on the results of experiments, we compared the stress-strain curves of prototype and model concrete mixes using a nondimensional basis. In order to simulate the stress-stain curves of prototype concrete, it is important that various mix proportions of model concrete selected properly which are varied from aggregate grading, cement-aggregate and sand-aggregate ratio.
