INTRODUCTION Today, the manufacturing industry makes con- stant effort in order to construct an E-manufacturing system using information technology for effective production control, and then, it offers the integrated production control to the workers, the production managers, and the consumers, etc. (Lee, 2003; Choi, 2004). In the mould manufacturing industry, the process managers often request paperwork to know the information of the processes on CNC machine tools or they visit the shop… 相似文献

Ballerinas use their ankle joints more extremely and sustain injuries on the ankle joint more frequently than non-dancers. Therefore, the ankle movement of dancers is important and should be studied to prevent injuries. Measuring ankle joint range of motion (ROM) using radiographs could demonstrate the contribution to motion of each joint. The aim of this study was to analyse and compare ankle joint movements and the ratio of each joint’s contribution during movement between dancers and non-dancers, using radiographic images. Dancers have lower dorsiflexion (26.7 ± 6.2°), higher plantarflexion (74.3 ± 7.1°) and higher total (101.1 ± 10.8°) ROMs than non-dancers (33.9 ± 7.0°, 57.2 ± 6.8° and 91.1 ± 9.3°, respectively) (p < 0.05). Although the ROMs were different between the two groups, the ratios of each joint movement were similar between these two groups, in all movements. Regarding total movement, the movement ratio of the talocrural joint was almost 70% and other joints accounted for almost 30% of the movement role in both dancers and non-dancers. Therefore, the differences in ROM between dancers and non-dancers were not a result of a specific joint movement but of all the relevant joints’ collaborative movement. 相似文献

Understanding scientific phenomena requires comprehension and application of the underlying causal relationships that describe
those phenomena (Carey 2002). The current study examined the roles of self-explanation and meta-level feedback for understanding causal relationships
described in a causal diagram. In this study, 63 Korean high-school students were randomly assigned to one of three conditions:
instructional explanation, self-explanation, and meta-level feedback. Results showed that self-explaining a causal diagram
was as effective as studying instructional explanations. Furthermore, the effectiveness of self-explaining a causal diagram
was enhanced by meta-level feedback that prompted students to reflect on their own explanations by comparing them with instructional
explanations. We identified three main difficulties that high-school students experienced when explaining a causal diagram
to themselves: one-sided explanation, erroneous explanation, and the lack of inference. Implications of the study were discussed
in regard to the improvement of self-explanation and the design of causal diagrams in science education. 相似文献

The aim of the present study is to shed light on the conceptions that young students have of heat and temperature, concepts that are both important in school science curricula and closely related to daily life. The subjects of the study were students from a rural district in South Korea and they ranged in age from 4 to 11 years. Interviews were conducted with each student on the basis of questions on temperature, thermal insulation, and heat equilibrium. After calculating the frequency and percentage of student responses and analyzing the rationale for their answers, it was found that younger students tended to view temperature as “size” or a “summation of numbers.” This tendency gradually diminished in older students. Most students had alternative conceptions of thermal insulation regardless of age; however, reasoning differed according to age. Younger students displayed a greater tendency to view insulation as a material property, whereas older students showed a greater tendency toward rational heat and temperature conceptions. Most students did not have clear concepts of heat equilibrium regardless of age, but possessed numerous alternative conceptions. © 2007 Wiley Periodicals, Inc. J Res Sci Teach 44: 284–302, 2007 相似文献

Lessons of love: Psychoanalysis and teacher-student love 总被引:1,自引:0,他引:1

What is the relation of love and pedagogy? Two recent phenomena have called into question whether love has any place within pedagogy at all: teacher‐student sexual scandal and the standardization movement. As love walks the thin line between inspiration and sex, and as standardization has assumed love to be synonymous with bias, it has become more important than ever to provide a clear account of love and its relation to teaching. For this account, I turn to Lacanian psychoanalysis and, in particular, to Lacan's contentious claim that “There is no such thing as a sexual relationship.” Through an explication of Lacan's position on love, I conclude that love not only has a place within pedagogy but is necessary for it. 相似文献

The purpose of the study was to explore a conceptual structure of graduate teaching assistant (GTA) teaching concerns. Results indicated that GTAs experience five distinct, inter-related types of concerns: class control, external evaluation, task, impact and role/time/communication. These ‘teaching concerns’ were further analysed by examining their relationship with the value placed on them by the GTAs and the confidence in dealing with the teaching-related issues of concern. The results revealed that GTAs tend to have concerns about self, task or role/time/communication-related issues when the nature of the concerned issues is perceived as being valuable but challenging. On the other hand, GTAs are more likely to have concerns with impact-related issues when the nature of the issues is perceived as both being valuable and manageable. Several GTA characteristics, such as teaching experience, teacher efficacy, participation in professional development and values on teaching practices, were examined as predictors of GTA teaching concerns. 相似文献

This study investigates the relationship between communication overload and uses of diverse communication channels in terms of their level of synchronicity. Emphasis on the synchronicity of any given channel reveals how temporal elements (i.e., rate and processing time) play an important role in perceptions of communication load. Additionally, this study examines the association between communication overload, organizational identification and job satisfaction. Findings reveal: (a) both high and low synchronous channels are associated with increased reports of communication overload; (b) a mediating effect of organizational identification on the relationship between communication overload and job satisfaction; and (c) a moderating effect of communication overload on the relationship between low synchronous channels and organizational identification. 相似文献

This study investigated whether and how exposure to tanned images on television is related to tanning attitudes and intentions among men and women, using the influence of presumed influence model (Gunther & Storey, 2003). The model showed a better fit with the male rather than female sample. In addition, among males, exposure to tanned-men images on television was directly associated with protanning attitudes and was indirectly associated with protanning intentions. Corresponding direct and indirect associations were not found among females. Instead, the results suggest females may project their own protanning intentions into the estimation of protanning norms among male and female peers. These results suggest the social perceptual processes underlying the link between television exposure and tanning tendencies of men and women may differ. 相似文献
