Stage 1

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.

This study investigated factors that influence public school speech-language pathologists' acceptance and/or resistance to computer technology. Significant differences were found between speech-language pathologists who are frequent users of computers in the workplace and those who seldom or never use them. These differences were attributed to differences in attitudes toward computers, available funding for computers, in-service training, and physical facilities.

The Relationship ◽

Situational Test

Advances in computer technology have created opportunities for the development of a multimedia situational test in which responses are filmed with a webcam. This paper examined the relationship of a so-called webcam test with personality, cognitive ability, job experience, and academic performance. Data were collected among 153 psychology students. In line with our expectations, scores on the webcam test, intended to measure interpersonally oriented leadership, were related to extraversion, conscientiousness, emotional stability, and job experience. Furthermore, the webcam tests significantly predicted students’ learning activities during group meetings over and above a cognitive ability test and a personality questionnaire. Overall, this study demonstrates that webcam tests can be a valid complement to traditional predictors in selection contexts.
