Enterprise resource planning (ERP) is an increasingly widely utilized educational model globally. Several scholars have suggested that user satisfaction and intention to use can each effectively affect learning performance. However, whether user satisfaction and learning performance are related remains unclear. This study has the following four objectives: to examine the primary determinants of user learning satisfaction in an ERP environment; to determine how user satisfaction, intention to use, and learning performance are related to each other; to determine whether intention to use affects learning performance and mediates the relationship between user satisfaction and learning performance, and to evaluate the effectiveness of the proposed model in explaining the effects of the learner interface, interaction and attitude of the instructor toward the student on user satisfaction, supporting evaluation of mediation learning performance by intention to use. The results of SEM analysis indicate that the model that is proposed exhibits goodness-of-fit. Interface design and cognitive function significantly and positively influence learning performance. User satisfaction and intention to use both significantly and positively affect learning performance. Intention to use mediates the relationship between between user satisfaction and learning performance.

This study constructs a novel blood pressure measurement device without the air cuff to overcome the problem of discomfort and portability. The proposed device measures the blood pressure through a mechanism that is made of silicon rubber and pressure transducer. The system uses a microcontroller to control the measurement procedure and to perform the necessary computation. To verify the feasibility of the constructed device, ten young volunteers were recruited. Ten blood pressure readings were obtained using the new system and were compared with ten blood pressure readings from bedside monitor (Spacelabs Medical, model 90367). The results indicated that, when all the readings were included, the mean pressure, systolic pressure and diastolic pressure from the new system were all higher than those from bedside monitor. The correlation coefficients between these two were 0.15, 0.18 and 0.29, for mean, systolic and diastolic pressures, respectively. After excluding irregular apparatus utilization, the correlation coefficient increased to 0.71, 0.60 and 0.41 for diastolic pressure, mean pressure and systolic pressure, respectively. We can conclude from these results that the accuracy can be improved effectively by defining the user regulation more precisely. The above mentioned irregular apparatus utilization factors can be identified and eliminated by the microprocessor to provide a reliable blood pressure measurement in practical applications in the future.
