Published: September 2017

ABSTRAKElektrokardiograf adalah perangkat untuk mengukur aktifitas kelistrikan jantung. Sinyal yang ditampilkan oleh perangkat elektrokardiograf adalah sinyal elektrokardiogram (EKG). Untuk monitoring ECG minimal diperlukan satu lead sementara untuk standar klinis diperlukan 12 lead. Untuk realisasi perangkat EKG 12 lead diperlukan strategi agar jumlah perangkat keras yang dibutuhkan semakin sedikit sehingga dimensi menjadi lebih kecil. Untuk mengatasi permasalahan tersebut, pada penelitian ini dirancang perangkat EKG 12 lead dengan teknik multipleksing. Kombinasi sadapan sinyal EKG 12 lead dikontrol oleh multiplekser 4051 melalui mikrokontroler secara bergantian. Data dijital hasil konversi ADC selanjutnya dikirim secara serial ke komputer server dan dapat dilihat pada komputer client yang terhubung. Hasil yang didapat menunjukkan bahawa perangkat analog telah berhasil mengakuisisi sinyal EKG dengan baik dari Lead I sampai Lead V6. Dengan waktu pensakelaran sebesar 5 ms, sinyal tidak dapat ditampilkan secara simultan 12 lead. Sinyal dapat diakuisisi dengan baik jika waktu pensakelaran sebesar 5 detik namun seluruh sadapan sinyal EKG tidak dapat ditampilkan secara simultan.Kata kunci: Elektrokardiograf, 12 Lead, Multipleksing, Server, Client.

For monitoring ECG, at least need one ECG lead meanwhile for standard clinical ECG need 12 lead. For realization of 12 lead ECG devices, it is need strategy to reduce number of hardware to make dimension of ECG device smaller. To solve this problem, we use multiplexing method for ECG device development. Combination of 12 lead ECG signal is controlled by the multiplexer 4051 through microcontroller sequentially. Digital data of ADC is sent serially to the server computer and can be viewed on client computer that connected to the network. From the results obtained indicate that analog devices have been successfully acquired ECG signals Lead I to Lead V6. With 5 ms switching time, the 12 lead ECG signal can not be displayed simultaneously. The signal can be acquired properly with 5 seconds switching time, but the whole of ECG signals can not be displayed simultaneously.Keywords: Electrocardiograph, 12 Lead, Multiplexing, Server, Client.

ABSTRACT Information Technology (IT) has significant influence to a company. The robust network IT infrastructure should be installed earlier, supporting the information exchange through internet or intranet and it also should be easily accessible via wired or wireless network. PDII-LIPI (Pusat Dokumentasi dan Informasi Ilmiah - Lembaga Ilmu Pengetahuan Indonesia) Jakarta is an organization under LIPI which focuses on three processes for instance the documentation services, the information services and the development of documentation services. PDII-LIPI has already used IT to support those businesses so they must carefully choose the best network IT infrastructure. To achieve this objective, we propose a research which design wired and wireless network infrastructure at PDII – LIPI. We use Network Development Life Cycle (NDLC) as a method for solving problem. This method is very useful in developing wired and wireless network infrastructure and it can monitor network performance.

Impaired reproduction after exposure to ADHD drugs: Systematic review of animal studies
Authors: Danborg Pia Brandt , Simonsen Anders Lykkemark , Gøtzsche Peter C. 
Published: September 2017

BACKGROUND: Few studies have reported on long-term harms caused by ADHD drugs but they are known to impair growth. OBJECTIVE: To assess whether ADHD drugs impair reproduction in mammals. METHODS: Systematic review of reproduction in studies of animals treated with ADHD drugs. DATA SOURCES: PubMed, Biosis and EMBASE. RESULTS: We included 17 studies. The studies were generally of poor quality or poorly reported. Two studies reported the use of one of three advised randomisation methods. Fifteen studies used placebo which suggested blinding. On clonidine, the ability to produce offspring was reduced for male rats, which approached two females each. In one study, 10 treated rats produced no offspring while all four controls did. In another study, 10 treated rats impregnated nine females while 10 controls impregnated 16. On methylphenidate, vaginal opening was delayed in two studies (in one, the mean difference was 4.0 days, 95% CI 2.5 to 5.6, and number of estrous cycles was halved; in the other, the minimum delay was 6 days), while in two other studies no difference occurred. Generally, the impairments improved after a drug-free period and were less pronounced when treatment started later in life. CONCLUSION: ADHD drugs impair the reproduction in animals.

Abstract
The Ultra-Violet Imaging Telescope (UVIT) is one of the payloads in ASTROSAT, the first Indian Space Observatory. The UVIT instrument has two 375 mm telescopes: one for the far-ultraviolet (FUV) channel (1300–1800 Å), and the other for the near-ultraviolet (NUV) channel (2000–3000 Å) and the visible (VIS) channel (3200–5500 Å). UVIT is primarily designed for simultaneous imaging in the two ultraviolet channels with spatial resolution better than 1.″8, along with provisions for slit-less spectroscopy in the NUV and FUV channels. The results of in-orbit calibrations of UVIT are presented in this paper.
Improved Point-source Detection in Crowded Fields Using Probabilistic Cataloging
Authors: Portillo Stephen K. N. , Lee Benjamin C. G. , Daylan Tansu , Finkbeiner Douglas P. 
Published: September 2017

Abstract
Cataloging is challenging in crowded fields because sources are extremely covariant with their neighbors and blending makes even the number of sources ambiguous. We present the first optical probabilistic catalog, cataloging a crowded (∼0.1 sources per pixel brighter than 22nd mag in F606W) Sloan Digital Sky Survey r-band image from M2. Probabilistic cataloging returns an ensemble of catalogs inferred from the image and thus can capture source–source covariance and deblending ambiguities. By comparing to a traditional catalog of the same image and a Hubble Space Telescope catalog of the same region, we show that our catalog ensemble better recovers sources from the image. It goes more than a magnitude deeper than the traditional catalog while having a lower false-discovery rate brighter than 20th mag. We also present an algorithm for reducing this catalog ensemble to a condensed catalog that is similar to a traditional catalog, except that it explicitly marginalizes over source–source covariances and nuisance parameters. We show that this condensed catalog has a similar completeness and false-discovery rate to the catalog ensemble. Future telescopes will be more sensitive, and thus more of their images will be crowded. Probabilistic cataloging performs better than existing software in crowded fields and so should be considered when creating photometric pipelines in the Large Synoptic Survey Telescope era.
