Abstract

The paper describes development activities of an e-health system for community health center (Puskesmas) with integrated adverse drug events e-prescription module, consist of system design and development, human resource development, e-health system realization, laboratory and implementation test of e-health system. Some e-readiness evaluations were conducted, through a number of field visits and questionnaires. The results had been used in the e-health system design and development, installation of the internet access infrastructure, and implementation of the education and hands-on training for the medical and administrative staff of the healthcare units. After completing the e-health system design and development as well as system realization and laboratory tests stages, a series of field implementation and experiments have been successfully conducted at Puskesmas Babakansari in Bandung. A number of users feed back have been obtained and used for further improvements on both of the software and hardware modules. The e-health system with integrated e-prescription module has successfully developed and shown its expected functions in: patient registration, medical record, paperless prescription, producing the required reports and preventing possible adverse drug events.Key words: Adverse drug events, community health center, e-health, e-prescription  e-Prescription: Sistem e-Health untuk Pencegahan Adverese Drug Event di PuskesmasAbstrakArtikel ini mendeskripsikan pengembangan sistem e-health untuk puskesmas dengan modul e-prescription yang terintegrasi adverse drug event.

Abstract

Segmental Sinusoidal Model for Speech Signal Coding. Periodic signal can be decomposed by sinusoidal component with Fourier series. With this characteristic, it can be modeled referring by sinusoidal form. By the sinusoidal model, signal can be quantized in order to encode the speech signal at the lower rate. The recent sinusoidal method is implemented in speech coding. By using this method, a block of the speech signal with 20 ms to 30 ms width is coded based on Fourier series coefficients. The new method proposed is quantization and reconstruction of speech signal by the segmental sinusoidal model. A segment is defined as a block of the speech signal from certain peak to consecutive peak. The length of the segment is variable, instead of the fixed block like the recent sinusoidal method. Coder consists of the encoder and the decoder. Encoder works to code speech signal at variable rate. Then coded signal will be transmitted to receiver. On the receiver, coded signal will be reconstructed, so that the reconstruction signal has the near quality compared with the original signal. The experimental results show that the average of segmental SNR is more than 20 dB.

Abstract

Simple ML Detector for Multiple Antennas Communication System. In order to support providing broadband wireless communication services against limited and expensive frequency bandwidth, we have to develop a bandwidth efficient system. Therefore, in this paper we propose a closed-loop MIMO (Multiple-Input-Multiple-Output) system using ML (Maximum Likelihood) detector to optimize capacity and to increase system performance. What is especially exciting about the benefits offered by MIMO is that a high capacity and performance can be attained without additional frequency-spectral resource. The grand scenario of this concept is the attained advantages of transformation matrices having capability to allocate transmitted signals power suit to the channel. Furthermore, product of these matrices forms parallel singular channels. Due to zero inter-channels correlation, thus we can design ML detector to increase the system performance. Finally, computer simulations validates that at 0 dB SNR our system can reach optimal capacity up to 1 bps/Hz and SER up to 0.2 higher than opened-loop MIMO.
