Published: February 2019

Background: Anxiety among primigravida mothers should be handled to avoid the risks during pregnancy. Hypnotherapy is considered to be a solution; however, there are limited studies to determine its effect on anxiety, especially in primipara mothers.
Objective: To examine the effect of hypnoanxiety on the level of anxiety in primigravida.
Methods: This was a Randomized Controlled Trials (RCTs) with pretest-posttest design, conducted between September – October 2016 in the working area of the Health Center of Bergas Semarang, Indonesia. There were 40 respondents recruited using simple random sampling, which divided into intervention and control group. Hypnoanxiety was performed 8 times for 4 weeks. The Zung Self-Rating Anxiety Scale (ZSAS) was used to measure anxiety in pregnant women. Data were analyzed using Mann Whitney test and Kruskal Wallis test.
Results: Findings showed that after four weeks intervention, there was a decrease of the level of anxiety in the intervention group, consisted of 25% of moderate anxiety, 40% of mild anxiety, and 35 % of respondents with no anxiety. The p-value was 0.05, which indicated that there was mean difference of anxiety level between intervention and control group.
Conclusions: There was a significant effect of hypnoanxiety on the level of anxiety in pregnant women. It is suggested that hypnoanxiety could be one of the alternative therapies to reduce the anxiety among pregnant women. This could be considered to be included in the standard of midwifery care in Indonesia.

Background: Quality of life is the individuals’ perception of their place in life in the context of the cultural system and values in which they live, along with their goals, expectations, and worries. Retirement is an adaptable period that results in a change of role, changes in social interactions, and limited financial resources.
Aim: This study aims to analyze the factors that affect post power syndrome and quality of life of the elderly.
Methods: The design of this research was a correlation study with a cross-sectional approach. The population consisted of 44 retired elderly individuals. Purposive sampling was applied to the determined sample size. The independent variables were physiological stressors, psychological stressors and aging attitudes. The dependent variables were post-power syndrome and the quality of life of elderly people. The data were analyzed using Structural Equation Modeling- Partial Least Square (SEM-PLS) with a significance t statistic ≥ 1.96.
Results: The findings showed all of the significant indicators measured to the variable factor. Physical stressor factors affect post-power syndrome with a t value of 2.366, and psychological stress factors affect post-power syndrome with a t value of 3.326. Aging behavior factors affects post-power syndrome with a t statistic of 5.296 and the post-power syndrome effect on the quality of life of the elderly has a t value of 7.689.
Conclusion: There were significant effects in relation to physiological stressor factors, psychological stress factors, and aging attitudes towards post-power syndrome. There was an influence of post-power syndrome on the quality of elderly life.

Published: February 2019

Background: Primary dysmenorrhea occurs because of the excessive amount of prostaglandins in the blood. Papaya leaf extract is considered to be able to reduce prostaglandin and menstrual pain.
Objective: This study aims to prove that papaya leaf extract (Carica Papaya L.) can decrease the level of menstrual pain and prostaglandin levels in primary dysmenorrhea.
Methods: A true experimental study with randomized pretest posttest control group design. There were 32 samples recruited using simple random sampling, with 16 each assigned to an experiment group and a control group. Numerical Rating Scale (NRS) was used to measure menstrual pain, and the level of prostaglandin was measured using the enzyme-linked immunosorbent assay (ELISA) method. Independent t-test and paired t-test were performed for data analysis.
Results: There was statistically significant difference of menstrual pain and prostaglandin level before and after intervention with p-value 0.000 (<0.005), which indicated that papaya leaf extract had a significant effect on reducing menstrual pain. The decrease of menstrual pain in the experimental group was -3.375 and in the control group was -3.438; while the decrease of prostaglandin level in the experimental group was -56.971 and in the control group was -57.557.
Conclusion: Provision of papaya leaf extract (Carica Papaya L.) significantly decreased the level of menstrual pain and prostaglandin levels in primary dysmenorrhea. Papaya leaf extract can be used as a safe and effective herbal medicine for primary dysmenorrhea which has almost the same efficacy as mefenamic acid.
Ноктюрн М. Глинки для фортепиано или арфы и его культурно-автобиографические смыслы
Authors: Timchenko-Byhun Inna 
Published: February 2019

Статья посвящена рассмотрению культурно-автобиографических смыслов Ноктюрна Es-dur М. Глинки (1828 г.) для фортепиано или арфы, изначально ориентированного на два инструмента. Анализ художественной мотивации такого композиторского решения позволяет осознать значение этого раннего сочинения в пианизме Глинки. Внимание сконцентрировано на каждом из трех смысловых маркеров названия сочинения: ноктюрн (как жанр пианизма Глинки) – арфа и ноктюрн – фортепиано и ноктюрн. Рассматривается значение жанра ноктюрна в пианизме Глинки, а также смыслы, связанные с его арфовой и фортепианной интерпретациями. Используются перспективный и ретроспективный векторы рассмотрения – т.е., осмысление направленности композиторских поисков в конце 20-х годов, а также констатация принципов, которые сформировались в этом сочинении и впоследствии закрепились в фортепианном стиле Глинки.
Вірш О. Пушкіна «Я возмужал среди печальных бурь» у двох музичних прочитаннях українських композиторів – Є. Станковича та Ю. Іщенка
Authors: Tugusheva Nataliya 
Published: February 2019

У статті розглянуто ІІ частину Камерної симфонії № 4 «Пам’яті Поета» Є. Станковича, а також романс для голосу з фортепіано Ю. Іщенка. Центральним для Станковича став образ «небесної лазурі», що вплинуло на загальний просвітлений та умиротворений характер музики. Іщенко акцентує внутрішню напругу, сумніви та тривогу як домінантні образи. Об’єднуючим елементом музичних прочитань виступила гармонія, якій обидва композитори відвели першочергову роль.

Abstract
As part of our ongoing search for technosignatures, we collected over three terabytes of data in 2017 May with the L-band receiver (1.15–1.73 GHz) of the 100 m diameter Green Bank Telescope. These observations focused primarily on planetary systems in the Kepler field, but also included scans of the recently discovered TRAPPIST-1 and LHS 1140 systems. We present the results of our search for narrowband signals in this data set with techniques that are generally similar to those described by Margot et al. Our improved data processing pipeline classified over 98% of the approximately six million detected signals as anthropogenic radio frequency interference (RFI). Of the remaining candidates, 30 were detected outside of densely populated frequency regions attributable to RFI. These candidates were carefully examined and determined to be of terrestrial origin. We discuss the problems associated with the common practice of ignoring frequency space around candidate detections in radio technosignature detection pipelines. These problems include inaccurate estimates of figures of merit and unreliable upper limits on the prevalence of technosignatures. We present an algorithm that mitigates these problems and improves the efficiency of the search. Specifically, our new algorithm increases the number of candidate detections by a factor of more than four compared to the results of Margot et al.
Photon Bubbles in a Self-gravitating Dust Gas: Collective Dust Interactions
Authors: Mendonça J. T. , Guerreiro A. , Ali S. 
Published: February 2019

Abstract
We consider broadband radiation interacting with a gas of self-gravitating dust grains. We show that photon-bubble formation can occur, due to a modified Jeans instability, which will imply the formation of two different kinds of dust density perturbations. This could be useful for understanding the B-mode signal observed in the CMB polarization survey, and other astrophysical processes, such as the formation of protoplanets and voids in dust clouds.
Molecular Cloud Cores in the Galactic Center 50 km s−1 Molecular Cloud

Published: February 2019

Abstract
The Galactic center 50 km s−1 molecular cloud (50MC) is the most remarkable molecular cloud in the Sagittarius A region. This cloud is a candidate for the massive star formation induced by cloud–cloud collision (CCC) with a collision velocity of ∼30 km s−1 that is estimated from the velocity dispersion. We observed the whole of the 50MC with a high angular resolution (∼2.″0 × 1.″4) in Atacama Large Millimeter/submillimeter Array cycle 1 in the H13CO+
J = 1−0 and C34S J = 2−1 emission lines. We identified 241 and 129 bound cores with a virial parameter of less than 2, which are thought to be gravitationally bound, in the H13CO+ and C34S maps using the clumpfind algorithm, respectively. In the CCC region, the bound H13CO+ and C34S cores are 119 and 82, whose masses are 68% and 76% of those in the whole 50MC, respectively. The distribution of the core number and column densities in the CCC are biased to larger densities than those in the non-CCC region. The distributions indicate that the CCC compresses the molecular gas and increases the number of the dense bound cores. Additionally, the massive bound cores with masses of >3000 M
⊙ exist only in the CCC region, although the slope of the core mass function (CMF) in the CCC region is not different from that in the non-CCC region. We conclude that the compression by the CCC efficiently formed massive bound cores even if the slope of the CMF is not changed so much by the CCC.
Constraining Metallicity-dependent Mixing and Extra Mixing Using [C/N] in Alpha-rich Field Giants

Abstract
Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several mechanisms have been proposed to explain this mixing, better empirical constraints are necessary. Here, we use [C/N] abundances in 26,097 evolved stars from the SDSS-IV/APOGEE-2 Data Release 14 to trace mixing and extra mixing in old field giants with −1.7 < [Fe/H] < 0.1. We show that the APOGEE [C/N] ratios before any dredge-up occurs are metallicity dependent, but that the change in [C/N] at the first dredge-up is metallicity independent for stars above [Fe/H] ∼ −1. We identify the position of the red giant branch (RGB) bump as a function of metallicity, note that a metallicity-dependent extra mixing episode takes place for low-metallicity stars ([Fe/H] < −0.4) 0.14 dex in log g above the bump, and confirm that this extra mixing is stronger at low metallicity, reaching Δ[C/N] = 0.58 dex at [Fe/H] = −1.4. We show evidence for further extra mixing on the upper giant branch, well above the bump, among the stars with [Fe/H] < −1.0. This upper giant branch mixing is stronger in the more metal-poor stars, reaching 0.38 dex in [C/N] for each 1.0 dex in log g. The APOGEE [C/N] ratios for red clump (RC) stars are significantly higher than for stars at the tip of the RGB, suggesting additional mixing processes occur during the helium flash or that unknown abundance zero points for C and N may exist among the RC sample. Finally, because of extra mixing, we note that current empirical calibrations between [C/N] ratios and ages cannot be naively extrapolated for use in low-metallicity stars specifically for those above the bump in the luminosity function.
High-resolution Optical Spectropolarimetry of Nova V339 Del: Spatial Distribution of Nova Ejecta during the Early Phase of Explosion
Authors: Kawakita H. , Shinnaka Y. , Arai A. , Arasaki T. , Ikeda Y. 
Published: February 2019

Abstract
High-resolution spectropolarimetric observations of V339 Del were performed in the optical wavelength region every night from UT 2013 August 15.49 to 21.23 (corresponding to the pre- and near-maximum phases of the nova) to reveal the asymmetry of the nova ejecta shortly after the explosion. Observed polarization spectra showed intrinsic line polarization for Hα, O i
λ777.3 nm, Si ii
λλ634.7, 637.1 nm, in addition to intrinsic continuum polarization. The line polarization of Hα on August 15.49 (+0.91 day post-discovery) indicates an expanding nova ejecta, which contains a torus surrounding the nova photosphere. The line polarization of O i
λ777.3 nm is also consistent with this hypothesis. The line polarizations of Si ii
λλ634.7, 637.1 nm might indicate a variation in the photospheric temperature of the nova on the same date. Based on the day-by-day changes of the intrinsic continuum and line polarization found in the observations, it can be concluded that the effective geometry of V339 Del had changed from a torus-dominant to a bipolar-shaped geometry between +0.91 and +2.15 days post-discovery. The intrinsic continuum polarization became weaker after +2.93 days due to the larger size of the expanding nova ejecta. This is consistent with high-angular observations of V339 Del with a near-infrared interferometer and with a recent nova ejecta model that can explain the γ-ray emission and dust formation found in V339 Del.

Abstract
Stellar populations are powerful tools for investigating the evolution of extragalactic environments. We present the first UV integrated-light spectroscopic observations for 15 young star clusters in the starburst M83 with a special focus on metallicity measurements. The data were obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. We analyze the data by applying an abundance technique that has previously been used to study an optical set of star clusters. We estimate a central metallicity of [Z] = +0.20 ± 0.15 dex, in agreement with estimates obtained through independent methods, i.e., J band and blue supergiants. We estimate a UV metallicity gradient of −0.041 ± 0.022 dex kpc−1, which is consistent with the optical metallicity gradient of −0.040 ± 0.032 dex kpc−1 for

. Combining our stellar metallicities, UV and optical, with those from H ii regions (strong-line abundances based on empirical calibrations), we identify two possible breaks in the gradient of M83 at galactocentric distances of R ∼ 0.5 and 1.0 R
25. If the abundance breaks are genuine, the metallicity gradient of this galaxy follows a steep-shallow-steep trend, a scenario predicted by three-dimensional numerical simulations of disk galaxies. The first break is located near the corotation radius. This first steep gradient may have originated in recent star formation episodes and a relatively young bar (<1 Gyr). In the numerical simulations, the shallow gradient is created by the effects of dilution by outflow, where low-metallicity material is mixed with enriched gas. Finally, the second break and last steep gradient mark the farthest galactocentric distances where the outward flow has penetrated.
A Broad HCO+ Absorption Line Associated with the Circumnuclear Torus of NGC 1052

Abstract
We present the first subparsec-scale maps of HCO+
J = 1–0 absorption in the circumnuclear region of the nearby radio galaxy NGC 1052. Our λ3 mm very-long-baseline-interferometry (VLBI) observations with the Korean VLBI Network have spatially resolved the broad HCO+ absorption at a velocity range of 1350–1850 km s−1 against a double-sided nuclear jet, and have revealed that the HCO+ absorption is concentrated on the receding jet and the nuclear components. The distribution of the HCO+ absorbing gas strongly supports the circumnuclear torus surrounding the supermassive black hole. From the estimations of the column density and the volume density of molecular hydrogen, the size of the molecular gas region in the torus is at least 1 pc. The broad spectral profile of HCO+ is likely to be a blend of multiple gas clumps with various velocities. The HCO+ absorption of NGC 1052 could trace complex kinematics in the vicinity of the active galactic nucleus, such as inflow, outflow, turbulence, and so on.

Abstract
Infrared excesses due to dusty disks have been observed orbiting white dwarfs with effective temperatures between 7200 and 25,000 K, suggesting that the rate of tidal disruption of minor bodies massive enough to create a coherent disk declines sharply beyond 1 Gyr after white dwarf formation. We report the discovery that the candidate white dwarf LSPM J0207+3331, via the Backyard Worlds: Planet 9 citizen science project and Keck Observatory follow-up spectroscopy, is hydrogen dominated with a luminous compact disk (L
IR/L
⋆ = 14%) and an effective temperature nearly 1000 K cooler than any known white dwarf with an infrared excess. The discovery of this object places the latest time for large-scale tidal disruption events to occur at ∼3 Gyr past the formation of the host white dwarf, making new demands of dynamical models for planetesimal perturbation and disruption around post-main-sequence planetary systems. Curiously, the mid-infrared photometry of the disk cannot be fully explained by a geometrically thin, optically thick dust disk as seen for other dusty white dwarfs, but requires a second ring of dust near the white dwarf’s Roche radius. In the process of confirming this discovery, we found that careful measurements of WISE source positions can reveal when infrared excesses for white dwarfs are co-moving with their hosts, helping distinguish them from confusion noise.

Published: February 2019

Cham Islands (Cu Lao Cham) is a group of 8 small islands in the Quang Nam province, Central Vietnam. There is only one study that mentioned the diversity of marine molluscs in this area. However, the data on species composition have not been digitised and not stored or shared for other purposes. Our paper aims to share the checklist of marine mollusc species (Bivalvia and Gastropoda) species that we collected from the littoral zone of Cham Islands in May 2017. This is the first digitised and online data of marine molluscs in Vietnam. It is very important for researchers in various fields such as the structure and function of ecology and biodiversity monitoring.
This study provides a checklist of the marine bivalves and snails in the Cham Islands of Vietnam. Moreover, this first widely shared data of biodiversity in Vietnam can trigger biodiversity data papers in this data-poor country.
The data of this study will be important inputs for better understanding biodiversity on the Cham Islands and Vietnam as well as for forming the basis for monitoring, exploitation and conservation of biodiversity in this area.
In total, 145 taxa were recorded, 46 bivalve taxa and 99 snail taxa, from which 128 were identified to the species level and 17 were identified to the genus level. There are 116 new species records for the Cham Islands.
The specimens are currently deposited in the Institute of Ecology and Biological Resources (IEBR), Vietnam Academy of Science and Technology (VAST).
Réglementation de l’industrie bancaire et exclusion financière dans la Communauté économique et monétaire de l’Afrique centrale
Authors: Avom Désiré , Bobbo Amadou 
Published: February 2019

Cet article met en évidence les effets pervers, notamment l’exclusion financière, nés de la réglementation de l’industrie bancaire dans la Communauté économique et monétaire de l’Afrique centrale (CEMAC). Il expose d’abord le dispositif réglementaire en vigueur, mis sur pied en 1992 avec la création de la COBAC. Il montre ensuite que les efforts déployés par les banques pour s’adapter à cette réglementation influencent leurs choix stratégiques qui se traduisent par deux formes d’exclusion financière : une première induite par la stratégie de localisation des banques et une deuxième engendrée par la politique de l’offre des services bancaires.
