Purpose - Although ensuring that all the organizational members know their roles exactly is an important part of managerial work, few studies address the role clarity in food manufacturing and distribution firms. Role clarity refers to the extent to which individuals clearly understand the tasks, duties, responsibilities, and expectations of their work roles (Hinkin & Schriesheim, 2008). The purpose of this study is to examine the effect of the role clarity on organizational commitment and the mediating role of creativity in the role clarity-organizational commitment relationship. Research design, data, and methodology - Data were collected from 297 employees in food manufacturing and distribution firms of Korea by self-evaluations questionnaires. The unit of the analysis for testing is an individual. We proposed four hypotheses: (1) is about the relationship between role clarity and organizational commitment, (2) is about the relationship between role clarity and creativity, (3) is about the relationship between creativity and organizational commitment, and (4) is about the mediating role of creativity. We conducted the hierarchical regression analysis for testing the main and mediating effects. Results - The results of the study indicated that the role clarity was positively associated with organizational commitment and creativity. Results also indicated that the creativity was positively associated with organizational commitment. Especially, the impact of the role clarity on organizational commitment was mediated by creativity. Conclusions - An important contribution of this study is extending prior theory on the relationship between role clarity and organizational commitment by shedding new light on assumptions regarding the mediating effect of creativity. The results demonstrate that the role clarity has an indirect effect as well as a direct effects on organizational commitment. Our research suggests important implications for organizations that pursue to stimulate their employees' creativity, emphasizing the importance of the role clarity. This study has several potential limitations. Maybe the most serious limitation is its cross-sectional study design. Another limitation is the use of employees' self-reports to measure the variables. In the future, researchers should employ a longitudinal study design and use diverse sources of data.

Purpose: The purpose of this study was to examine the relationship among emotional clarity in emotional intelligence, maternal identity, and fetal attachment to measure how emotional clarity and maternal identity impact on fetal attachment and to determine mediating effects of maternal identity in pregnant women at the time of diagnosis with gestational diabetes mellitus (GDM). Methods: This study used a correlational survey design. 88 pregnant women with GDM completed a study questionnaire of emotional clarity, maternal identity, and fetal attachment immediately after the diagnosis of GDM. Data were analyzed Mann-Whitney U test, and ANOVA with Duncan test, Pearson correlation, three-step regressions to test mediating effect, and Sobel test. Results: The emotional clarity was positively related with maternal identity and fetal attachment. It affected maternal identity with 21.9% of explained variance. The emotional clarity and the maternal identity were significant predictors of fetal attachment by 57.7% of explained variance. The maternal identity mediated the relationship between emotional clarity and fetal attachment. Conclusion: The results suggest that a nursing program to enhance the emotional clarity and the maternal identity needs to be developed as an effective strategy to improve fetal attachment.

This study investigates the phonetic meaning of clarity and turbidity(淸濁) that has been used in psychoacoustics, musicology, and linguistics in both the East and the West. With a view to clarifying the phonetic meaning of clarity and turbidity, this study conducts three perception tests. First, 34 subjects were asked to take one of Clear and Turbid by forced choice for 5 pure and complex tones, respectively, ranging from A2 to A6 differing by octave. Second, they were asked to select between the two choices for 25 pure and complex tones, respectively, ranging from A2 to A4 differing by semitone. Third, they were asked to opt for one of the two choices for 8 different vowels of different formant and fundamental frequencies. Results showed that there is a certain range of tone which is perceived as clear, that clarity level increases as fundamental frequency increases, and that pure tones have a higher level of clarity than complex ones, fundamental frequency being equal. Results also showed that vocal tract resonance enhances clarity level on the whole, and that lower vowels have a higher level of clarity than higher ones. This study is significant in that it demonstrates that clarity level is proportional to fundamental frequency and the first formant frequency, all else being equal.

The present study aims to investigate the effects of sound diffusers and absorbers on the sound clarity in classrooms. In order to do this, computer simulations were carried out to find the effective area of treatment which could enhance the sound clarity in the room. Acoustic measurements were undertaken in a lecture room with several conditions changing the surface of walls and ceilings with diffusers and absorbers. Diffusion and absorption treatments were applied to the side walls, rear wall and the ceiling of the classroom. SPL, RT, D50, RASTI were measured at 9 measurement points with one sound source and MLS was used as the sound source signal. The results show that higher sound clarity was obtained when diffusers were applied to rear walls and ceiling rather than side walls. Also, it was confirmed that absorption increased sound clarity more effectively with smaller amount in comparison with diffusers. It was also concluded that the effects of sound diffusers and absorbers on the sound clarity could be obtained distinctly at the rear area of the classroom.

In this study, we propose a new method to control both the beat clarity and beat period in a ring structure. An equivalent ring which satisfies the measured mode condition is determined by using the equivalent ring theory. Theoretical analysis and finite element analysis on the equivalent ring are performed to investigate the effect of the local structural modification on the beat clarity and beat period. Beat clarity and period are improved by attaching asymmetric mass or decreasing local thickness. Through the analysis on the equivalent ring, the proper position and the amount of the local variation are determined to satisfy the required clarity and period condition. All the analysis results are compared and verified by the experiment.

There have been numerous studies on the enhancement of noisy speech signal. In this paper, we propose a new speech enhancement method, that is, a filtering of a dissonant frequency combined with noise suppression algorithm. The simulation results indicate that the proposed method provides a significant gain in voice clarity. Therefore if the proposed enhancement scheme is used as a pre-filter, the perceptual clarity of husky voice is greatly enhanced.
