Factors Affecting Compliance Paying BPJS Kesehatan Mandiri in Road Care Patients in Hospitals
Authors: SRI HANDAYANI  
Published: November 2020

Compliance is consistency or inconsistency to instructions or rules. Compliance in paying dues means the behavior of someone to pay dues appropriately based on a predetermined time. In Kota Solok, 5,758 (61%) did not have compliance in paying contributions. The irregularity of JKN participants in paying dues will have an impact on the guarantee of health services in available health facilities, one of which is the Level IV Hospital of Solok City in collaboration with BPJS Health.
This study aims to determine the factors associated with compliance paying independent BPJS contributions to outpatients at Level IV Hospital in Solok City. This type of research is a quantitative study using a cross sectional study design. The population in this study were patients participating in the BPJS Mandiri who visited the Outpatient Installation of Level IV Hospital in Solok City with an average of 77 visitors each month. The samples in this study were 64 samples taken using the accidental sampling method. Data analysis performed was univariate and bivariate analysis with chi square test.
Based on the results of the study note that of 64 respondents there are 64.1% who are compliant in paying BPJS Health contributions independently. Variables related to compliance paying dues in outpatients at Level IV Hospital in Solok City were education (p=0.002), employment (p=0.002), income (p=0.004), knowledge (p=0.002), perception (p=0.019) and motivation (p=0.039). Suggestions to BPJS Health to provide socialization or information to BPJS Health participants about the BPJS Health Program from the time of payment, method of payment, and sanctions for delinquent payments.
Spectroscopic Tomography: A First Weak-lensing Detection Using Spectroscopic Redshifts Only
Authors: Dell’Antonio Ian , Sohn Jubee , Geller Margaret J. , McCleary Jacqueline , von der Linden Anja 
Published: November 2020

Abstract
We describe the first spectroscopic tomographic (spectrotomographic) weak-lensing measurement for a galaxy cluster based only on background galaxies with spectroscopically determined redshifts. We use the massive cluster A2029 to demonstrate the power of combining spectroscopy and lensing to obtain accurate masses and to overcome biases from contamination and photometric redshift errors. We detect the shear signal from the cluster at > 3.9σ significance. The shear signal scales with source redshift in a way that is consistent with the angular diameter distance ratio variation in a ΛCDM universe. Furthermore, the amplitude of the measured signal is consistent with the X-ray mass. Upcoming spectroscopic instruments such as the Prime Focus Spectrograph on Subaru will permit spectrotomographic weak-lensing measurements with a signal-to-noise ratio comparable with current photometric-redshift-based weak-lensing measurements for hundreds of galaxy clusters. Thus, spectrotomography may enable sensitive cosmological constraints that complement and are independent of other measurement techniques.

We present measurements of the size of the quasar proximity zone (R

p
measurement down to

mag, where more common quasar populations dominate at the epoch. We restrict the sample to quasars whose systemic redshifts have been precisely measured by [C ii] 158 μm or Mg ii
λ2798 emission lines. We also update the R

p
measurements for 26 luminous quasars presented in Eilers et al. by using the latest systemic redshift results. The luminosity dependence on R

p

p

proper Mpc), which could be the result of their young age (<104 yr) in the reionization epoch, though statistics on this are still scarce.
The H i Structure of the Local Volume Dwarf Galaxy Pisces A
Authors: Beale Luca , Donovan Meyer Jennifer , Tollerud Erik J. , Putman Mary E. , Peek J. E. G. 
Published: November 2020

Abstract
Dedicated H i surveys have recently led to a growing category of low-mass galaxies found in the Local Volume. We present synthesis imaging of one such galaxy, Pisces A, a low-mass dwarf originally confirmed via optical imaging and spectroscopy of neutral hydrogen (H i) sources in the Galactic Arecibo L-band Feed Array H i survey. Using H i observations taken with the Karl G. Jansky Very Large Array, we characterize the kinematic structure of the gas and connect it to the galaxy’s environment and evolutionary history. While the galaxy shows overall ordered rotation, a number of kinematic features indicate a disturbed gas morphology. These features are suggestive of a tumultuous recent history and represent

% of the total baryonic mass. We find a total baryon fraction

if we include these features. We also quantify the cosmic environment of Pisces A, finding an apparent alignment of the disturbed gas with nearby, large-scale filamentary structure at the edge of the Local Void. We consider several scenarios for the origin of the disturbed gas, including gas stripping via ram pressure or galaxy–galaxy interactions, as well as accretion and ram pressure compression. Though we cannot rule out a past interaction with a companion, our observations best support the suggestion that the neutral gas morphology and recent star formation in Pisces A are a direct result of its interactions with the intergalactic medium.

Abstract
The chemical homogeneity of surviving stellar clusters contains important clues about interstellar medium (ISM) mixing efficiency, star formation, and the enrichment history of the Galaxy. Existing measurements in a handful of open clusters suggest homogeneity in several elements at the 0.03 dex level. Here we present (i) a new cluster member catalog based only on APOGEE radial velocities and Gaia-DR2 proper motions, (ii) improved abundance uncertainties for APOGEE cluster members, and (iii) the dependence of cluster homogeneity on Galactic and cluster properties, using abundances of eight elements from the APOGEE survey for 10 high-quality clusters. We find that cluster homogeneity is uncorrelated with Galactocentric distance,

, age, and metallicity. However, velocity dispersion, which is a proxy for cluster mass, is positively correlated with intrinsic scatter at relatively high levels of significance for [Ca/Fe] and [Mg/Fe]. We also see a possible positive correlation at a low level of significance for [Ni/Fe], [Si/Fe], [Al/Fe], and [Fe/H], while [Cr/Fe] and [Mn/Fe] are uncorrelated. The elements that show a correlation with velocity dispersion are those that are predominantly produced by core-collapse supernovae (CCSNe). However, the small sample size and relatively low correlation significance highlight the need for follow-up studies. If borne out by future studies, these findings would suggest a quantitative difference between the correlation lengths of elements produced predominantly by Type Ia SNe versus CCSNe, which would have implications for Galactic chemical evolution models and the feasibility of chemical tagging.
Deep Modeling of Quasar Variability

Published: November 2020

Abstract
Quasars have long been known as intrinsically variable sources, but the physical mechanism underlying the temporal optical/UV variability is still not well understood. We propose a novel nonparametric method for modeling and forecasting the optical variability of quasars utilizing an AE neural network to gain insight into the underlying processes. The AE is trained with ∼15,000 decade-long quasar light curves obtained by the Catalina Real-time Transient Survey selected with negligible flux contamination from the host galaxy. The AE’s performance in forecasting the temporal flux variation of quasars is superior to that of the damped random walk process. We find a temporal asymmetry in the optical variability and a novel relation—the amplitude of the variability asymmetry decreases as luminosity and/or black hole mass increases—is suggested with the help of autoencoded features. The characteristics of the variability asymmetry are in agreement with those from the self-organized disk instability model, which predicts that the magnitude of the variability asymmetry decreases as the ratio of the diffusion mass to inflow mass in the accretion disk increases.
Energy-preserving Integrators for Post-Newtonian Lagrangian Dynamics
Authors: Huang Li , Mei Lijie 
Published: November 2020

Abstract
Equations of motion derived from the Euler–Lagrange formula are usually implicit differential equations in terms of accelerations for the post-Newtonian (PN) Lagrangian dynamics of general relativistic problems. Meanwhile, the Legendre transform is in a nonclosed form due to the high nonlinearity of the velocity in the PN Lagrangian. To numerically integrate the exact implicit equations of motion rather than the truncated equations, the nontruncated strategy with an additional iteration for the Legendre transform is needed. In this paper, we aim at exploring energy-preserving methods accompanying the nontruncated strategy for the PN Lagrangian dynamics, once noticing that energy preservation as well as symplecticity is one of the most important properties of the Hamiltonian system that is completely equivalent to the PN Lagrangian. Incorporating the nontruncated strategy into the continuous-stage Runge–Kutta method, we thus propose a novel class of practical energy-preserving schemes. Numerical results from the PN Lagrangian circular restricted three-body problem and the spinning compact binaries show that the proposed numerical scheme is of high efficiency and can preserve energy nearly as accurately as machine precision.
Analysis of the core microstructure of terrigenic reservoirs based on lithological-petrographic studies to support the creation of digital core model
Authors: Belozerov IP , Gubaidullin MG , Yuriev AV 
Published: November 2020

The question of digital core modelling appears highly relevant due to the fact that there is not always a sufficient amount of core material available from studied wells: in some cases, it is not possible to select core material (in case of loose, weakly cemented rocks); in others, such material may be completely absent. In order to create a computer model of a digital core, it is necessary to have a correct understanding of the pore space microstructure and rock lithological composition and structure, among the most important features determining the quality of sedimentary reservoir rocks. Such information can be obtained by carrying out lithological-petrographic studies of thin sections of reference (standard) core samples.
The aim of the present work is to study petrographic thin sections for their further use in creating a digital core model. The article discusses the methodology and results of laboratory lithological and petrographic studies of thin sections using the available core information.
The paper presents the results of laboratory studies of thin sections of terrigenous sandstones obtained from the Berea Sandstone formation (USA). The choice of the Berea Sandstone is due to its wide recognition by specialists, as well as its homogeneity, both in terms of the grain size of constituent rocks and their filtration and reservoir properties. The work also presents the results of data analysis on lithological and petrographic studies of core material from the terrigenous deposits obtained in the Timan-Pechora province in northern Russia.
The research results can be used for mathematical modelling of the pore space microstructure in a digital core model.
Hydrate Management in Restart Operations of a Subsea Jumper

Published: November 2020

Abstract
Subsea jumpers are tie-in systems with a characteristic M-shaped geometry, employed to connect subsea facilities such as wellhead trees to manifolds. During well restart after a prolonged shut-down, subsea jumpers are exposed to a significant driving force for hydrate formation. Employing the recently-constructed HyJump flowloop, designed to mimic subsea jumpers operating at hydrate forming conditions, an experimental campaign was conducted to assess the influence of pipeline temperature, gas flow rate, liquid inventory, and inhibitor content on hydrate deposition during simulated shut-down and restart operations. In this work, we acquired baseline data on the gas sweep efficiency in HyJump for a wide range of gas restart velocities to characterize hydrodynamic behaviour in the absence of hydrates. Preliminary experiments were also conducted to evaluate the jumper operability in hydrate forming conditions.
The HyJump flowloop consists of a test section connected to independent gas and liquid injection equipment at the inlet and gas separation facilities at the outlet which allows a continuous recirculation of gas and a once-through pass of the liquid. The test section has a complex geometry, with three identical low points and two high points with horizontal length of 12′ 10˝ and 7′ 7˝, respectively, and total height is 13′ 2˝. The test section is equipped with 12 pressure and temperature sensors regularly distributed, a MEG sensor in the second low point, a throttling valve downstream of the first high point to mimic the wellhead choke, and a viewing window at the outlet. In gas sweep experiments, each of the three low points was loaded with 1.6 gallons of water and natural gas at 1200 psi. During these tests, the pipeline temperature was maintained above 60 °F where hydrates are not expected to form. The system was maintained for six hours at a pipeline temperature of 41 °F (17 °F sub-cooling) for hydrate formation tests. Gas sweep velocities were varied in a range between 0.06 and 3 ft/s.
The results illustrate that a superficial gas velocity of 3 ft/s was required to fully remove liquids from the jumper. However, gas velocities below 0.16 ft/s did not result in any substantive changes to the liquid inventory. Thus, low flow restart conditions could offer a significant driving force for hydrate formation in the jumper at low temperature. The preliminary gas restart tests conducted in hydrate forming conditions provided clear evidence of hydrate deposition at gas velocities below 0.16 ft/s.
Hydrate formation in subsea jumper spools is poorly understood and a rare topic of discussion within scientific literature. This unique "HyJump" facility offers new insight to assist operators mitigate the risk of hydrate blockage by manipulating gas restart rates after well shut-down in the absence of (or with severely limited) chemical inhibition.

ABSTRACT

Background:
Hypertension is a major contributor to the global burden of disease and global mortality, with a projection of 39.1 million cases in Nigeria by the year 2030.

Aim:
The aim of this study was to evaluate the effect of body mass index on blood pressure (BP) and blood glucose in three rural agrarian communities in Enugu State, Nigeria.

Materials and Methods:
This was an opportunistic cross-sectional study in three rural agrarian communities––Ibagwa, Akpugo, and Egede, all in Enugu State. Volunteer adults of 18 years and above were consecutively recruited and screened. Omron BP monitors were used mostly and supplemented by mercury BP sphygmomanometers. Each participant had their BP measured after at least 5 min of rest, and repeated twice after 3–5 min interval and also received a questionnaire about demographics, lifestyle, and environmental factors. Hypertension was defined as a systolic BP equal to or more than 140mm Hg and/or diastolic BP equal to or more than 90mm Hg or in those on treatment for hypertension. Ethical approval was obtained and all participants gave informed consent before screening. Data were collated and analyzed.

Result:
People of middle (40–64 years) and elderly (>65 years) age groups constituted the majority of participants. Most of the participants in the three groups had normal body mass index. The proportion of participants with hypertension was 15.2%, 21.9%, and 31.9% for Ibagwa, Akpugo, and Egede communities, respectively. The mean BMI was 27.08 kg/m2, 24.70 kg/m2 and 24.45 kg/m2 for participants from Ibagwa, Egede, and Akpugo communities, respectively. Prevalence of overweight and obesity was higher among Ibagwa people, whereas the prevalence of underweight was higher among Egede people (P < 0.001).

Conclusion:
Low proportion of participants had hypertension in the three communities and rising age was more associated with hypertension than overweight and obesity.

ABSTRACT

Background:
COVID-19 pandemic is a very common menace in the world. Knowledge on mode of spread and prevention of COVID-19 remains blurred among mothers who visit children clinics.

Objectives:
This work is aimed to determine the knowledge of mode of spread and preventive practices among mothers presenting in a health institution.

Materials and Methods:
This is a cross-sectional observational study undertaken in a health institution in South East Nigeria using a structured self-administered questionnaire. Data entry and analysis were done using IBM Statistical Package for Social Sciences (SPSS) statistical software version 25.0.

Results:
All the respondents (100.0%) have heard of COVID-19. A minor proportion of the respondents, 31.9%, had good knowledge of the mode of spread of COVID-19. Majority of the respondents, 93.3%, knew that COVID-19 could be prevented through good use of personal hand sanitizer. A high proportion of the respondents, 75.5%, were aware that COVID-19 could be prevented by avoiding crowded places and 76.7% by wearing of face mask. The respondents who were in the age group 30–39 years were twice more likely to have good knowledge of spread of COVID-19 when compared with those who were 50 years and above. (AOR = 2.2, 95%CI: 1.2–3.9). The respondents who attained tertiary education were 1.3 times less likely to have good knowledge of spread of COVID-19 when compared with those who attained secondary education. (AOR = 0.8, 95%CI: 0.5–1.2). Respondents who were married were about five times more likely to have good preventive practices against COVID-19 than those who were single parents. (AOR = 4.9, 95%CI: 2.8–8.4).

Conclusion:
Education is predictive of knowledge of mode of spread while being married is predictive of knowledge of preventive practices.

Authors: Halásková Martina , Halásková Renata 
Published: November 2020

The article deals with funding of sport at the regional level in the Czech Republic. The paper aims to evaluate sport and leisure activities, focusing on allocated public expenditures from regional budgets in self-governing regions in the Czech Republic. Relations between public expenditures on sport and public expenditures on leisure activities and recreation from regional budgets of the Czech Republic in years 2010 and 2018 are tested by using correlation and regression analysis. The results showed differences between self-governing regions in the Czech Republic in public expenditures on sport and leisure activities and recreation per capita as a share of the total regions’ expenditures in 2010 and 2018, which were also corroborated by the regression model. The allocated financial resources of self-governing regions in the Czech Republic are mainly related to the general economic potential, demographic and political factors of and preferences in funding of the individual areas of the public sector.
Legal Protection of the Commune's Own Tasks in Meeting the Collective Needs of the Community as far as a Municipal Marketplace is Concerned on the Ground of Polish Infractions' Law
Authors: Budyn-Kulik Magdalena 
Published: November 2020

One of the commune's own tasks is to meet the collective needs of the community. The most important issue from this perspective is the place designated for commerce. The commune may designate such a place on on the territory owned or managed by it. This designated place is called the market, which is every place where the sale is carried out. The regulations in force in Poland show some inconsistency in the approach to sales conducted in places other than shops. On the other hand, the use of the municipal market entails payment of the market fee, the objective scope of which raises doubts. Sale outside the designated place constitutes an infraction punishable by a fine. Its object of protection is public order and peace. The act consists in conducting sales activity. It may be committed by anyone, both intentionally and unintentionally. The offender is subject to punishment even in the case of a one-off, small sale, but it is possible to waive the penalty.

Abstract
Women are a growing proportion of individuals with SCI and have distinctive health needs spanning the life course that demand deliberate consideration and clinical expertise. Practitioners caring for women with SCI must incorporate broad medical knowledge of SCI physiology and health promotion for women, including differences in complication rates following SCI, and work collaboratively with rehabilitation, medical, and surgical specialists to optimize function and health for women with SCI. Clinical researchers must continue to perform population-based studies to best characterize the evolving needs of women with SCI and evaluate treatment efficacy and care delivery models to best serve this population.
