Conflicts between individuals are quite natural and they can act as an positive contributing factor not only to the development of an individual but also to the organization to which one belongs. But too much conflicts will always induce dissatisfaction and stresses, which will be destructive and harmful to all of them, and that is why we are always tying to seek(find) out the causes for the origination of conflicts and remedies to cope with them effectively. The present study, as the first one in a series of studies which our researchers contemplate executing, was designed to develop a measure of job satisfaction for dental laboratory technicians. One job satisfaction measure and two job satisfaction related measures, one for faithfulness for the job and the other for environmental characteristics of dental laboratory were newly developed. The newly developed measures were comprised of a total of 38 items, which were each 12 items for job satisfaction and faithfulness for the job and 14 items for environmental characteristics of dental laboratory With the aid of factor analysis for principal components and categorization of items by panel of professionals, items of each measure were grouped into 2-4 subscales. Contribution to internal consistency was the fina) criterion for an item's inclusion in a subscale. Internal consistency reliability of each item was attested through the statistical analysis on the data obtained from 55 structured questionnaires. Reliability of internal consistency of subscales in each measure of job satisfaction and faithfulness for the job ranged from 0.74 to 0.79 and 0.90-0.91 respectively. The result from this research came to draw the following conclusions. 1. Validity and internal consistency reliability of all the items of each measure was attested. 2. The newly developed measure of job satisfaction was found to be appropriate for (measuring the degree of job satisfaction of) dental technicians, as well as for (other) dental office personnels.

The phase separation of multiple competing structural/ferroelectric phases has attracted particular attention owing to its excellent electromechanical properties. Little is known, however, about the strain-gradient-induced electronic phenomena at the interface of competing structural phases. Here, we investigate the polymorphic phase interface of bismuth ferrites using spatially resolved photocurrent measurements, present the observation of a large enhancement of the anisotropic interfacial photocurrent by two orders of magnitude, and discuss the possible mechanism on the basis of the flexoelectric effect. Nanoscale characterizations of the photosensitive area through position-sensitive angle-resolved piezoresponse force microscopy and electron holography techniques, in conjunction with phase field simulation, reveal that regularly ordered dipole-charged domain walls emerge. These findings offer practical implications for complex oxide optoelectronics.
