A tool for the analysis below 100 kHz of pulsed current waveforms with reference to human exposure has been developed. It consists of a dedicated program written in Matlab. As input data, a trapezoidal pulsed current waveform has been considered, and, varying the rise time and the duty-cycle, a parametric analysis has been performed. Also a noise superimposed to the signal has been considered. Parameters relevant to human exposure have been calculated following the ICNIRP Guidelines. A schematic operative diagram for metal inert gas welding applications is proposed; an experimental set-up has been built and the obtained results are reported.

The medical costs for elderly people in Taiwan have increased largely due to the increasing number of aging people in the country. To meet the goals and requirements of the National Health Insurance (NHI), designing and providing a program which would reduce the unnecessary medical services demanded by elderly people is needed. In this research, a conceptual service model of the telecare system applied in Taiwan is discussed and presented. The service model is discussed in three dimensions, namely, service, delivery, and content. In the service dimension, the services provided by telecare service should be accessible and responsible. In the delivery dimension, telecare service should be highly interactive and with high usability. Finally, in the content dimension, the content of telecare service must be individualized and based on userspsila needs. Most importantly, it must be comprehensive and authentic. Telecare service can be used as an important tool to assist nurses in nursing homes. It should be delivered by skilled nurses to increase the confidence of users. In district hospitals, doctors can substitute the weekly telecare service for traditional medical service. Therefore, the costs of NHI can be reduced. Moreover, the accessibility and interactivity of telecare service will give users greater satisfaction. The cooperation of nursing homes and district hospitals in the telecare service will not only improve the quality of long-term care but will also pave the way for the practice of telecare service in Taiwan.

The container delivery lead-time for the international logistics differs widely between Hong Kong and Yantian port, which is analyzed in this paper. As for container transportation, problems such as factory inventory barely exist, although the issue of "time storage" (safety time) does matter in the process. The staying time of containers varies from port to port, and is much longer than the transportation time which in that case could be omitted in the whole delivery time. Unfortunately extraordinary delay is always ignored by the port logistics researchers both inside and outside China. Furthermore, we consider that the following factors will greatly affect the lead-time estimation of the whole process. These include the time uncertainty in some middle phases, the difficulties in postponing deadlines, the cost of the compensating measures taken, and the enterprise tolerance capability due to delivery damage. We studied the difference starting from the data of the two ports and explored some underlying causes for the delays. The preliminary analysis showed that the differences between the regulations of the study groups, regulations regarding customs supervision, and the port management styles and practices between the two areas were main causes of the time difference.

The clinical symptoms of metabolic disorders during neonatal periods are often not apparent. If not treated earlier, irreversible damages such as mental retardation or even death may occur. Therefore, practicing the newborn screening is essential to prevent newborns from these damages. In the paper, we propose a newborn screening system using Support Vector Machines (SVM) classification techniques to evaluate, interpret, and determine whether a newborn has metabolic disorder diseases. The raw data, i.e., substances concentrations, were collected from the Tandem Mass Spectrometry (MS/MS). In addition, based on the concept of Service-Oriented Architecture (SOA), we design the system under Web Services .NET environment. The system provides features including heterogeneous platforms, protocols, as well as applications. It can be integrated seamlessly into National Taiwan University Hospital Information systems later.
