Authors: Ariyanto Galdi 
Published: April 2018

Surabaya adalah salah satu kota pesisir yang ada di Indonesia. Salah satu permasalahan wilayah kota pesisir adalah adanya instrusi air laut. Intrusi air laut adalah menyusupnya air laut ke zona air tawar sehingga air tawar berasa asin. Permasalahan pokok sumberdaya air yang terjadi di beberapa kota besar di Indonesia adalah keragaman sistem akuifer, posisi dan penyebaran penyusupan/intrusi air laut baik secara alami maupun secara buatan yang diakibatkan adanya pengambilan air tanah berlebihan (mining yield) untuk kebutuhan domestik, maupun industri.
Tujuan dari penelitian ini adalah untuk mengetahui sebaran kawasan terintrusi air laut di Kota Surabaya berdasarkan kandungan khlorida (Cl) dalam air. Pengambilan sampel air dilakukan di 28 titik untuk selanjutnya dilakukan analisi laboratorium.
Berdasarkan hasil analisis data, diketahui bahwa 23 % wilayah di Kota Surabaya kondisi kualitas air tanahnya asin, 26 % payau dan sisanya pada kondisi tawar. Dibandingkan dengan tahun 2013, wilayah yang terintrusi air laut di Kota Surabaya mengalami penurunan, sehingga menunjukkan bahwa telah terjadi peningkatan kondisi kualitas air tanah di Kota Surabaya.

Published: April 2018

Peningkatan laju pertumbuhan penduduk dan industri mendorong peningkatan kebutuhan akan energi listrik. Salah satu penyedia kebutuhan energi listrik di wilayah Jawa, Madura, Bali (Jamali) adalah Waduk Saguling. Rata-rata produksi listrik Waduk Saguling dari tahun 1986-2014 adalah 2.334.318,138 MWh/tahun. Asupan air bagi Waduk Saguling adalah Daerah Aliran Sungai (DAS) Citarum Hulu dengan luas 2.340,88 km2. Waduk Saguling juga merupakan salah satu waduk yang membentuk waduk series di kaskade Citarum yang terdiri dari Waduk Saguling, Cirata, dan Jatiluhur. Pemanfaatan Waduk Jatiluhur sebagai waduk multiguna untuk sumber air baku, irigasi, dan PLTA pun masih belum optimal, hal ini ditandai dengan terjadinya kekurangan air di hilir pada musim kering dan air melimpas pada musim hujan. Tujuan optimasi Waduk Saguling pada penelitian ini adalah memaksimalkan penggunaan air sehingga dapat memenuhi kebutuhan bagi pembangkit listrik dan memenuhi kebutuhan air di downstream dengan mempertimbangkan prakiraan debit masa depan. Pendekatan prakiraan debit yang dilakukan dalam pengelolaan waduk adalah dengan metode korelasi spasial (hujan dan debit) atau metode kontinu serta dengan metode diskrit markov yang menggunakan prinsip model stokastik markov 3 kelas. Data debit inflow Waduk Saguling yang digunakan adalah data debit dari tahun 1986-2013. Pada metode korelasi spasial diperoleh kombinasi tipe PPPQt-1memiliki nilai korelasi sebesar 0,86 sedangkan untuk metode diskrit markov diperoleh nilai korelasi sebesar 0,804.

Published: April 2018

Purpose Distinct normal physiological patterns of fat conversion in vertebrae were described both for children and adults. Our aim was to evaluate the T1-weighted bone marrow pattern of the vertebral bodies in various sites along the scoliotic spine of children with adolescent idiopathic scoliosis (AIS). Methods We retrospectively evaluated spine MRI studies of children with AIS. Scoliosis radiographs were assessed for type of curvature according to the Lenke classification. A paediatric neuroradiologist assessed the T1-weighted signal of vertebral bodies in comparison with the adjacent disc and distinct patterns of fatty conversion within the apical and stable vertebral bodies. Statistical assessment was performed. Results MRI study of the spines of 75 children with AIS were assessed, 59 (79%) of whom were female, with an age range of nine to 19 years. The relative overall T1-weighted signal intensity of the vertebral body bone marrow relative to the intervertebral disc was hyperintense in 76% and isointense in 24%. Fatty conversion grade of the stable vertebra was higher than the apex vertebra (p = 0.0001). A significant tendency to have more advanced fat conversion patterns in the apex vertebra up to age 13.5 years old compared with adolescents above that (p = 0.015) was seen. Conclusion This preliminary study suggests a different pattern of bone marrow conversion in AIS from the normal physiologic pattern described in the literature. Whether these changes are secondary to the biomechanics of the curved spine or may suggest that bone marrow maturation rate and content have a role in the pathogenesis of AIS remains to be further researched.

Hop to it in the gig economy: The sharing economy and neo-liberal feminism
Authors: Shade Leslie Regan 
Published: April 2018

Abstract
This article examines two major sharing economy companies, Uber and TaskRabbit, describing how they comprise virtual work and articulate gendered relations through their promotional discourse and initiatives. By encouraging the empowering benefits of labour flexibility and entrepreneurialism for women, these companies exemplify a type of neo-liberal feminism, which endorses individualization and market-based solutions to employment. Given the contingent working conditions resident in the sharing economy, a more apt descriptor is the ‘gig economy’. The article also examines policy aspects of the sharing economy, including legal debates about worker status and platform discrimination.

Published: April 2018

Abstract

Background
Acute myocardial infarction (AMI) in pregnancy is a rare event and of the causes, coronary artery vasospasm (CAV) is considered even more uncommon.

Purpose
We present a new case report of a woman at 32 weeks of pregnancy with an AMI from CAV with a normal coronary angiogram. We performed a systematic review of similar cases of spontaneous AMI related to CAV to better understand its characteristics and management. AMI was defined as elevated cardiac enzymes (troponin or CKMB) with chest pain and/or electrocardiogram (EKG) changes consistent with ischemia.

Methods
We use the terms “acute myocardial infarction”, “myocardial infarction”, “coronary artery vasospasm” and “pregnancy” for our PubMed review. We also evaluated all references in identified manuscripts. Six cases of AMI in pregnancy due to CAV have been reported as of November 2016, including ours.

Results and conclusion
Six cases of AMI due to CAV during pregnancy or postpartum are reported in the literature, including ours. Patients experiencing this condition tend to be of advanced maternal age, multigravida and in their third trimester or postpartum. Successful management with a combination of long acting nitrates and/or calcium channel blockers achieved symptomatic control in all published cases. Obstetric outcomes were mostly normal, with the majority experiencing uncomplicated deliveries at term.
RBFPUM with QR Factorization for Solving Water Flow Problem in Multilayered Soil
Authors: Sadik Mohamed , Hassan Ben-Ahmed El , Wakrim Mohamed 
Published: April 2018

Abstract
We discuss the numerical modeling of infiltration in variably-saturated porous media. Richards’ equation is used to describe the infiltration towards the water table. It is difficult to accurately approximate its solution especially when we deal with layered soil due to its highly nonlinear fact. In this work, the nonlinearity is handled by using Gardner model. In the case of homogeneous soil, the linearized equation is solved using radial basis function partition of unity method (RBFPUM) with the introduction of QR factorization of Gaussian in order to enhance the numerical solution for small values of the so-called “shape parameter.” In the case of layered soil, domain decomposition principle is introduced. It is based on decomposing the general problem into many subproblems. The latter are solved by RBFPUM-QR and patched by using the Steklov–Poincaré equation. Infiltration towards water table in homogeneous and layered soil is considered as a numerical test.
External Quality Assessment of Glycated Hemoglobin in Iran: Comparison of Five Different Commercial Methods with Two Different Total Allowable Errors
Authors: Atabi Fereshteh , Mohammadi Reza 
Published: April 2018

Summary
Background: Glycated hemoglobin (HbA1c) measuring has a critical role in the monitoring and diagnosis of diabetes. So, the analytical performance of its measuring method must be acceptable. Clinical laboratories should continuously monitor the performance of their commercial methods, both by using proper internal quality control (IQC) and by participating in external quality assessment schemes (EQAS).
Methods: In January and August 2016, two different freshly prepared commutable patient QC samples were sent to over 1000 laboratories, but 682 and 925 different laboratories which were used five common commercial methods for measuring HbA1c, included in this study during 23th and 24th runs of the external quality assessment program (EQAP), respectively. Target values for total group and also for peer groups were calculated. The performance of each method and laboratory were determined according to two different allowable total errors (TEa), including ±6% and ±20%, which are suggested by the National Glycohemoglobin Standardization Program (NGSP) and Reference Health Laboratory of Iran, respectively.
Results: Considering TEa of ±20% in evaluating HbA1c commercial methods and laboratory performances, pass rates ranged from 97% to 98% during EQAP-23 and EQAP-24, respectively. But when this evaluation was performed according to TEa of ±6%, pass rates decreased significantly to 60% and 62%, respectively.
Conclusions: Using improper analytical goals has led to misinterpretation of EQA results. In order to maintain the clinical usefulness of HbA1c results, we need to reduce TEa of ±20% to ±6% and improve HbA1c measuring method performance. Although, with TEa of ±6% our pass rates are not so bad.
