The purpose of this paper is to review the major issues of between electronic trade and Ubiquitous computing. The rapidly developed environment by ubiquitous computing make the paradigm form e-trade to u-trade. This Article suggests an a-trade performance framework based on both field and literatures surveys. We propose some research subjects as well as practical implications for improving the performance of global c-trade under ubiquitous.

In case of applying electrokinetic remediation, magnitude of electric current is one of major factors for estimation of contaminant transport. In practice, electric current provide determination of electric conductivity based on specimen resistance. Electric current variation is produced during Electrokinetic remediation test. Electric current is decreased by expotential function according to time in condition of constant voltage. This can be interpreted as precipitation effect by OH$^{-10}$ generation in a cathode.

This study is to analyse whether the senior students' experience of graduation exhibitions would be of any practical use when they are employed by fashion industry. To address this theme, a survey is carried out for 73 fashion designers who participated into the exhibitions. Survey results show the graduation exhibitions are worth Not because skills learned from the experiences are applicable to the industrial practice, but because they provide them self-confidence of finishing four year programs successfully. They responded that graduation exhibitions are most effecive when they requires to utilize knowledges and skills acquired from all across the major subjects.

Brushless DC motors have a trapezoidal back EMF wave form and are fed with rectangular stator currents. Under these conditions, the torque produced is theoretcally constant. However, in practice, torque ripple may exist, one major cause of which conies from phase current commutation. In this paper we propose an improved method of reducing the torque ripple due to phase current commutation of indirectly restricting the uncommutated current through control of the other phase currents. Simulation results are present.

Compared to other variables being considered in therapeutics, patient compliance has long been given minor attention although it affects every aspect of medical care; Limited methodology of compliance measurement, in particular, has hampered major progress in research, and pre-conceptions have been reiterated. However, there is a recent surge in interest derived from new data revealed by reliable methods, i.g. continuous medication (compliance) monitoring. The visualization of dynamics in drug regimen compliance over time offers unique opportunities, both to scientific drug evaluation and therapeutics in medical practice. New perspectives related to the descriptive and explanatory side of the problem are outlined by giving examples from various therapeutic fields.

A prenatal chromosomal microarray (CMA) is generally recommended when a major anomaly is suspected on prenatal ultrasonography. As it can overcome the limitations of conventional karyotyping, it is expected that the number of prenatal CMA test requests will gradually increase. However, given the specificity of prenatal diagnosis, there are practical considerations compared to postnatal testing, such as the validation of prenatal specimens, maternal cell contamination, precautions when reporting variants of uncertain significance, and the need for comprehensive genetic counseling considering secondary findings. The purpose of this article is to provide necessary information to health care providers in consideration of these issues and to provide appropriate genetic counseling to patients.

As the nation is moving into the 21st century, the fundamental challenge facing local health departments in the United States is to improve the quality of peoples lives by preventing disease, injury, and disability through collaboration with public and private partners. During this century, life expectancy in the United States has increased remarkably from less than 50 years at the turn of the century to 79 years for woman and 72 years for men (CDC 1999; Bunker et al. 1994). Major portions of this gain can be attributed to advances in public health. (omitted)

This study investigated the Present status of laboratories for experiment and practice, and analyzed teachers' recognitions on experiment and practice for Home Economics area of a Technology and Home Economics curriculum according to majors of teachers. Questionnaires were mailed to middle school teachers who taught home economics part and they answered on the web. 220 replies were used for the final analysis. The findings were as follows: First, the facilities and teaching equipments of laboratories for home economics area were inferior, especially, for clothing and textiles part and housing part. Second, teachers recognized necessity to conduct experiment and practice highly. Food life part scored the highest, while housing part scored the lowest. Teachers who majored in home economics recognized more necessities of experiment and practice than teachers who didn't majored in home economics. Third, they recognized level of experiment and practice to be suitable to students, but 'maintenance and repair of housing' section was relatively less suitable than other sections. Fourth, 'making clothes and recycling' section was recognized to have the least suitability in quantities and hours of experiment and practice lesson, because of too much contents and lack of lesson hours. Fifth, teachers recognized that students were more interested in 'the basis of food preparation and practice' section, but they are less interested in 'maintenance and repair of housing' section. Sixth, teachers recognized that contents of experiment and practice were very useful to the real life. 'The basis of food preparation and practice' section was the most useful, while 'maintenance and repair of housing' section was the least useful. Seventh, experiment and practice lessons for food life part were put in practice very well, followed by the order of clothing and textiles part and housing part. Teachers who majored in home economics usually took more experiment and practice lessons than teachers who didn't major in home economics.

Objective: The objective of this paper is to examine the scope of ergonomics in relation to the discipline of industrial hygiene. Background: There has been increasing recognition of the importance of ergonomics in the practice of industrial hygiene. As a result, quite a number of ergonomics-related research articles have been published in major industrial hygiene journals. And the professional engineers in industrial hygiene have conducted ergonomics-related activities. Method: This paper reports the results from the literature review of the ergonomics papers published in major industrial hygiene journals for the last 5 years, and the certification of industrial hygiene and ergonomics. Results: It was found that 7.7~13% of the total published papers were about ergonomics, and the number of the professional engineers in industrial hygiene is almost double of that of ergonomics. Conclusion: It should be understood that the work of ergonomic is complementary to industrial hygiene and not in competition with it. Application: Some suggestions were proposed hopefully helpful to colleague ergonomists for future research.
