Based on the 2015 Intercensal Population Survey, the maternal mortality rate is still high at 305 per 100,000 live births. One of the efforts to prevent maternal death is through antenatal class activities which are group learning facilities for pregnant women to improve maternal knowledge and skills regarding pregnancy, childbirth, postpartum care and newborns. In Indonesia the antenatal class is still weak in its implementation although it is known to be very likely to reduce maternal mortality. This study aims to determine the factors that influence the class utilization of pregnant women in the work area of Puskesmas Lima Puluh Pekanbaru in 2018. This type of observational analytic quantitative research with cross sectional designe. The study population consisted of 315 third trimester pregnant women with a sample of 104 mothers. Data analysis was carried out in univariate, bivariate and multivariate. The results of the multivariate analysis showed that the variables that were significantly related to the utilization of the antenatal class were knowledge (POR: 4,248; CI 95%: 1,444-12,501), husband's support (POR: 3,707; 95% CI: 1,252-10,975), attitude (POR: 3,479; CI 95%: 1,210-9,997) and support from health workers (POR: 5,367; 95% CI: 1,758- 16,382). It is suggested to health workers to further enhance their role in providing health promotion on the importance of antenatal classes through mass media, electronic media and integrated counseling by establishing cross-program and cross-sectoral cooperation.

Energy efficiency is a set of measures to prevent the loss of energy in gas, steam, air and electricity, to reduce energy demand by recycling and evaluating various wastes, or to reduce production by advanced technology, more efficient energy resources, advanced industrial processes, and energy recovery. The International Energy Agency announced that world energy consumption increased by 45% since 1980 and would be 70% higher by 2030 [1]. The energy policy of the future will be on saving, energy efficiency and renewable energy trilogy. Today, with the industrial revolution, the environmental problems and the damages caused by the world we live in today have reached the dimensions that threaten human health and ecological balance. Considering that the energy consumed in the world is in buildings, every measure that reduces energy consumption is very important in terms of improving life conditions. For this purpose, the importance of renewable energy sources in the design of energy architecture principles in energy efficiency and sustainable environments is stated.

Published: March 2020

Current 4G - the fourth-generation wireless communication, which exists in most countries, represents an advance of the previous 3 generation wireless communication. However, there are some challenges and limitations, associated with an explosion of wireless devices, which cannot be accommodated by 4G. Increasing the proliferation of smart devices, the development of new multimedia applications, and the growing demand for high data rates are among the main problems of the existing 4G system. As a solution, the wireless system designers have started research on the fifth-generation wireless systems. 5G will be the paradigm shift that could provide with ultra-high data rate, low latency, an increase of the base station capacity, and the improved quality of services. This paper is a review of the changes through the evolution of existing cellular networks toward 5G. It represented a comprehensive study associated with 5G, requirements for 5G, its advantages, and challenges. We will explain the architecture changes – radio access network (RAN), air interfaces, smart antennas, cloud RAN, and HetNet. Furthermore, it discussed physical layer technologies, which include new channel modes estimation, new antenna design, and MIMO technologies. Also, it discussed MAC layer protocols. The article included three kinds of technologies: heterogeneous networks, massive multiple-input and output, and millimeter-wave. Finally, it explained the applications, supported by 5G, new features, various possibilities, and predictions.
Pileups and Migration Rates for Planets in Low-mass Disks
Authors: Dempsey Adam M. , Lee Wing-Kit , Lithwick Yoram 
Published: March 2020

Abstract
We investigate how planets interact with viscous accretion disks, in the limit that the disk is sufficiently low mass that the planet migrates more slowly than the disk material. In that case, the disk’s surface density profile is determined by the disk being in viscous steady state (VSS) while overflowing the planet’s orbit. We compute the VSS profiles with 2D hydrodynamical simulations, and show that disk material piles up behind the planet, with the planet effectively acting as a leaky dam. Previous 2D hydrodynamical simulations missed the pileup effect because of incorrect boundary conditions, while previous 1D models greatly overpredicted the pileup due to the neglect of nonlocal deposition. Our simulations quantify the magnitude of the pileup for a variety of planet masses and disk viscosities. We also calculate theoretically the magnitude of the pileup for moderately deep gaps, showing good agreement with simulations. For very deep gaps, current theory is inadequate, and we show why and what must be understood better. The pileup is important for two reasons. First, it is observable in directly imaged protoplanetary disks, and hence can be used to diagnose the mass of a planet that causes it or the viscosity within the disk. Second, it determines the planet’s migration rate. Our simulations determine a new Type-II migration rate (valid for low-mass disks), and show how it connects continuously with the well-verified Type-I rate.
Physical Origin of GeV Emission in the Early Phase of GRB 170405A: Clues from Emission Onsets with Multiwavelength Observations
Authors: Arimoto Makoto , Asano Katsuaki , Tachibana Yutaro , Axelsson Magnus 
Published: March 2020

Abstract
The origin of GeV emission from the early epoch of gamma-ray bursts (GRBs) is a widely discussed issue. The long gamma-ray burst GRB 170405A, observed by the Fermi
Gamma-ray Space Telescope, showed high-energy emission delayed by ∼20 s with respect to the X-ray emission, followed by temporally fading gamma-ray emission lasting for ∼1000 s, as commonly observed in high-energy GRBs. In addition, a high-energy spectral cutoff at ∼50 MeV was detected in the prompt-emission phase. If this feature is caused by pair-production opacity, the bulk Lorentz factor of the GRB ejecta can be estimated to be Γbulk = 170–420. Simultaneously with Fermi, GRB 170405A was observed by the Swift/Burst Alert Telescope and X-ray telescope, and a clear optical onset was detected ∼200 s after the burst by the Swift/Ultraviolet Optical Telescope. By coupling the deceleration time to the derived bulk Lorentz factor, the deceleration time was found to correspond to the delayed onset in the optical band. While the delayed onset in the optical band is evidence that this emission had an external shock origin, the temporally extended emission in the GeV band before the optical onset is hard to reconcile with the standard synchrotron emission from the same external shock. This may imply that the common feature of GeV emission with a power-law decay does not necessarily have the same origin as the optical afterglow in all GRBs detected by the Fermi/Large Area Telescope, particularly in their early epoch. Another mechanism to explain the GeV emission in GRB 170405A may be required, such as an internal shock or inverse Compton emission.
Unraveling the Nature of the Deeply Embedded Wolf–Rayet Star WR 121a
Authors: Arora Bharti , Pandey J. C. 
Published: March 2020

Abstract
An X-ray study of the deeply embedded Wolf–Rayet star WR 121a has been carried out using long-term (spanning over ∼12 yr) archival observations from Chandra and XMM-Newton. For the first time, a periodic variation of 4.1 days has been detected in the X-ray light curve of WR 121a. No companion is seen in a merged and exposure-corrected Chandra X-ray image of WR 121a, as found in other previous observations in the J band. The X-ray spectrum of WR 121a is well explained by a thermal plasma emission model with temperatures of 0.98 ± 0.34 keV and 3.55 ± 0.69 keV for the cool and hot components, respectively, and nonsolar abundances. The present study indicates that WR 121a is an X-ray-bright massive binary with an X-ray luminosity of ∼1034 erg s−1, which can be explained by active wind collision between its components. Phase-locked modulations have been seen in the flux variation of WR 121a where the flux increases by a factor of ∼1.6 from minimum to maximum in the 0.3–10.0 keV energy band. These variations could be caused by the wind collision region being eclipsed by the secondary star in a binary orbit. The winds of both components of WR 121a appear to be radiative. Radiative inhibition and radiative braking are the most likely processes that are severely affecting the wind collision in this short-period massive binary system.
L’avortement en Argentine : le refus de l’autonomie des femmes
Authors: Montoya Angeline 
Published: March 2020

Le 14 juin 2018, la chambre basse argentine prononça une délibération historique : par 129 voix contre 125 et une abstention, les député-e-s votèrent pour la légalisation de l’avortement pendant les quatorze premières semaines de grossesse. Après des décennies de mobilisation, il semblait que l’Argentine allait devenir le second pays d’Amérique du Sud, après l’Uruguay en 2012, à légaliser une pratique courante mais réalisée dans la plus complète clandestinité. Mais, moins de deux mois plus tard, le 9 août, le Sénat infligea un cruel revers aux pro-choix, rejetant le projet à 38 voix contre 31. L’article revient sur les moments marquants de la politisation de l’avortement en Argentine en relatant d’abord les débats de l’année 1994 et ceux succédant à la crise de 2001. Il analyse le choix stratégique du discours sur la vie pour les acteurs en présence, ainsi que le rôle de l’Eglise catholique pour laquelle l’enjeu principal est de conserver son poids sur les élites politiques et son pouvoir institutionnel, dans un contexte de plus grande pluralité religieuse. Le texte interroge finalement l’apparent paradoxe entre les remarquables avancées des droits et libertés LGBT, et le blocage politique concernant le droit des femmes à avorter en toute légalité et dans de bonnes conditions sanitaires.
L’interruption légale de grossesse dans la ville de Mexico : la convergence vertueuse d’exigences citoyennes, de changements législatifs, et de nouvelles politiques publiques
Authors: Márquez Murrieta Alicia , Robert Garance 
Published: March 2020

En 2007, l’assemblée législative du district fédéral de Mexico (aujourd’hui Ciudad de México) a voté une transformation légale très importante : la légalisation de l’avortement avant les 12 premières semaines de gestation. L’article expose les principaux éléments qui ont contribué à la légalisation, ainsi qu’une chronologie des quelques événements marquants de ce processus ; finalement, nous décrivons la mise en pratique de l’Interruption Légale de la Grossesse (ILG). L’article met en évidence le fait que suite à la loi, et d’une manière presque immédiate, des protocoles médicaux et sociaux ont été mis en place, de sorte que les femmes ont pu s’approprier rapidement les nouveaux dispositifs.
Les principautés de Flandre et de Hainaut aux XI e - XII e siècles : identité, perception, relations
Authors: Santinelli-Foltz Emmanuelle 
Published: March 2020

L’objectif de l’article est d’analyser, à partir de l’étude des relations sociales dans les sources narratives et diplomatiques, la perception des distinctions entre les principautés de Flandre et de Hainaut aux xi e - xii e siècles, leurs natures et leurs évolutions. Il montre ainsi comment elles sont perçues comme deux territoires distincts, avec leurs référents identitaires, puis comment leur situation de voisinage les conduit à entretenir des relations multiformes qui oscillent entre alliance, compétition et conflit, renforçant le sentiment d’appartenance à chacune d’elles, sans pour autant exclure de multiples perméabilités. Il en ressort, selon l’angle et l’échelle d’observation, différents types de disparités territoriales, notamment en termes de pouvoir : d’une part, divers indices laissent supposer la supériorité politique de la Flandre sur le Hainaut, même si c’est le comte hainuyer qui finit par s’imposer, à la fin du xii e siècle, à la tête des deux principautés ; d’autre part, la structuration de chacune des principautés conduit à la définition d’un centre et d’une périphérie dans lesquels le pouvoir s’ancre différemment ; enfin, l’affirmation identitaire des deux principautés n’exclut pas la reconnaissance d’entités territoriales plus petites (seigneuries) ou plus grandes (royaumes) à l’identité tout autant affirmée et avec lesquelles le pouvoir comtal doit tenir compte.
One-Year Outcomes From a Prospective, Randomized, Eye-to-Eye Comparison of Wavefront-Guided and Wavefront-Optimized PRK in Myopia
Authors: Smith Ryan G. , Manche Edward E. 
Published: March 2020

PURPOSE:
To compare wavefront-guided (WFG) and wavefront-optimized (WFO) photorefractive keratectomy (PRK) in patients with myopia using objective and self-reported quality of vision outcomes.

METHODS:
A total of 40 eyes from 20 participants were prospectively randomized to receive WFG or WFO PRK with the WaveLight Allegretto Eye-Q 400-Hz excimer laser (Alcon Laboratories, Inc., Fort Worth, TX). The primary outcome measured was uncorrected distance visual acuity (UDVA) at 12 months postoperatively. Secondary outcome measures included corrected distance visual acuity (CDVA), less than 5% and less than 25% contrast visual acuity, changes in higher order aberrations (HOAs), and self-reported quality of vision. Patients completed a validated, Rasch-tested, linear-scaled 30-item questionnaire assessing the quality of vision and visual symptoms preoperatively and at each visit.

RESULTS:

There was no statistically significant difference (
P
> .05) between the WFG and WFO groups in the frequency of attaining a refractive error within ±0.25 diopters of emmetropia, achieving postoperative UDVA of 20/16 or better or 20/20 or better, losing one or two or more lines or maintaining their preoperative CDVA, or differences in UDVA, CDVA, low contrast acuity, or HOAs. None of the measured quality of vision parameters exhibited statistically significant differences between the groups preoperatively or at 12 months postoperatively (all
P
> .05). The WFG and WFO groups each showed significant improvement in multiple subjective measures compared to pretreatment values in the same eye. A total of 12.5% of patients preferred their WFG PRK eye, 31.25% preferred their WFO PRK eye, and 56.25% had no preference at 12 months postoperatively.

CONCLUSIONS:
WFG and WFO PRK using the Alcon Wave-Light Allegretto Eye-Q 400-Hz excimer laser platform provide similar results and self-reported visual symptoms in myopic eyes at 12 months postoperatively.

Predictors of Patient Satisfaction After Refractive Lens Exchange With an Extended Depth of Focus IOL
Authors: Schallhorn Steven C. , Hettinger Keith A. , Teenan David , Venter Jan A. , Hannan Stephen J. , Schallhorn Julie M. 
Published: March 2020

PURPOSE:
To identify independent factors associated with postoperative satisfaction after refractive lens exchange with an extended depth of focus intraocular lens (EDOF IOL).

METHODS:
Patients who underwent a refractive lens exchange with bilateral implantation of the AT LARA 829MP IOL (Carl Zeiss Meditec, Jena, Germany) and attended the 3-month follow-up visit were included in the analysis (N = 351 patients). Demographics, preoperative and postoperative clinical parameters, and patient-reported outcomes were used in a regression model to determine predictors of 3-month postoperative satisfaction.

RESULTS:
The mean age of the study group was 58.2 ± 7.0 years (range: 45 to 79 years) and the mean preoperative sphere ranged between −12.50 and +6.75 diopters (D). At 3 months postoperatively, 86.6% of patients were very satisfied or satisfied with outcomes and 93.2% would recommend the procedure to their family or friends. Of all patients, 90.6% achieved binocular uncorrected distance visual acuity of 20/20 or better, 92.0% achieved binocular near vision of 20/50 or better, and 85.5% of eyes were within ±0.50 D of emmetropia. Logistic regression identified postoperative dry eye symptoms, binocular near and distance visual acuity, and glare symptoms as significant independent factors affecting patient satisfaction.

CONCLUSIONS:
Several factors were independently predictive of postoperative satisfaction after EDOF IOL implantation and addressing these may further improve patient satisfaction with the procedure, specifically, proper management of early symptoms of dry eye, ensuring good refractive predictability to maximize unaided vision, and counseling patients about the possibility of visual phenomena in the early postoperative period.

Authors: Dissanayake D. M. A. H. , Yasawardene A. D. K. S. N. , Kirihena R. A. 
Published: March 2020

Introduction A congenital piriform fossa sinus tract is thought to be caused by a developmental abnormality of the third or fourth pharyngeal arches. This condition is traditionally managed by an open approach, external excision of sinus tract with hemi-thyroidectomy. However, endoscopic cauterization of PFST is now recognized as a minimally invasive definitive first line therapeutic option. Objective To evaluate the success of endoscopic cauterization of the PFST as a definitive first line therapeutic option. Method Retrospective analysis was done on medical records of ten patients (aged 1-12y), who were diagnosed with PFST and underwent endoscopic diathermy cauterization of PFST during one-year period (2015/2016) at LRH. Data including demography, presentation, management and response to treatment were analyzed. Results Median age of our case series was 8.23 years and eight out of ten patients (80%) were males. The most common presentation was recurrent thyroid abscess 60% (6/10) and the side of the disease was left in 90% (9/10). Eight out of ten (80%) patients had complete closure of the PFST after one session of endoscopic diathermy cauterization. Two out of ten (20%) patients had to undergo two sessions. Average follow up period was 17 months. Conclusion We propose the endoscopic diathermy cauterization as a safe and definitive first line therapeutic option in the management of the PFST.

ObjectiveThe aim of this study was to systematically collect data of patients undergoing transsphenoidal hypophysectomy and analyse with regard to clinical presentation, short and long term complications and demographic details. Methods This is a prospective study of transsphenoidal pituitary surgery at National Hospital Sri Lanka from May 2013 to August 2019. 108 patients who underwent transsphenoidal hypophysectomy for pituitary tumours were included. All the patients who underwent the procedure for the first time and for revision surgery were included in the study. ResultsOut of 108 patients, there were 87 primary cases and 21 revision cases. The average age at presentation was 45.39 years. The youngest patient was 2 years and 6 months old while the oldest was 76 years. 55 patients were male and 53 patients were female. The most common complaint at presentation was headache which affected 36 patients (33.3%). The visual disturbance was the second most common presentation, occurring in 32 individuals (29.6%). 103 patients out of 108 have been operated using trans-nasal transseptal approach and rest (5) by trans labial transseptal method. The mean postoperative hospital stay was 9.8 days (range 3-17 days). The mean follow-up period was 35.7 months (range 3-75). 6 patients had died during the follow up period and 23 patients had defaulted follow up. Postoperative CSF leak occurred in 8 patients (7.4%) and anosmia was noted in 6 patients (5.5%). ConclusionMicroscopic transsphenoidal pituitary is a safe and effective treatment for pituitary tumours, and the commonest complication is CSF leak. Anosmia is one of the complications of this procedure.
