Upaya untuk mengurangi tingkat kebutuhan KB yang belum terpenuhi (unmet need for family planning) merupakan hal penting yang diperlukan untuk mencapai target kependudukan yang optimal. Penelitian ini bertujuan menyelidiki faktor-faktor determinan yang berkontribusi terhadap tingkat kebutuhan KB yang belum terpenuhi dengan menekankan pada peran penting tingkat intensi untuk memiliki anak pada kelompok wanita usia subur (WUS) yang berkeinginan menunda kelahiran anak. Hasil penelitian mengindikasikan tingkat kebutuhan KB yang tidak terpenuhi yang cukup tinggi, sebesar 16,7%, di empat kabupaten di Kalimantan Selatan tidak berhubungan secara signifikan dengan karakteristik individu dan keluarga WUS yang mencakup faktor-faktor demografis dan pengetahuan WUS atas alat/cara kontrasepsi dan efektivitasnya. Namun tingkat unmet need itu berkaitan dengan tingginya tingkat intensi atau keinginan WUS memiliki anak. Tingkat intensi memiliki anak yang tinggi mengandung arti ambivalen atau tidak konsisten dengan maksud untuk menunda kelahiran. Hasil penelitian ini mengimplikasikan semakin tinggi intensi ini yang juga berarti semakin ambivalen preferensinya maka semakin cenderung WUS tidak menggunakan alat/cara kontrasepsi. Terdapat kompleksitas di sekitar perilaku penggunaan alat kontrasepsi sehingga penyebabnya kemungkinan besar terletak pada determinan di luar faktor-faktor demografis.
Kata kunci: intensi fertilitas, keinginan memiliki anak, kebutuhan KB yang belum terpenuhi, unmet need for family planning.

During the Covid-19 pandemic, toddlers are the age group most vulnerable to the indirect effects of the pandemic but it has negative effects in the long term. This paper aims to analyze the impact of the Covid-19 pandemic on health services for children aged 6-45 months. The total sample in this study is 1,312 children under five who were obtained from a phone survey in one of the sub-districts in Nganjuk Regency. This study finds as many as 78.7% of children under five did not get the supplementary feeding program, about 85.7% of children under five did not receive growth and development monitoring program, and 7.3% of children under five during the pandemic had run out of or lacked drugs/vitamins. Using the Multivariate Logistic Regression, this study finds that the first children under five who did not receive the supplementary feeding program were those who lived in locations where the Posyandu did not open and did not visit or contacted by cadres or health workers. Second, toddlers who did not receive growth and development monitoring were those who live in locations where the Posyandu did not open, were not visited or contacted by Posyandu cadres or health workers, as well as toddlers with caregivers/parents who did not contact cadres/health workers. Third, the impact of the pandemic on household economic conditions and anxiety disorder has caused many children under five to run out of or lack medicines/vitamins.

This study aims to examine whether there are differences in the profitability performance of the telecommunications sub sector business entities on the Indonesia Stock Exchange in the period before the occurrence of Covid-19 and during the occurrence of Covid-19. To measure the profitability performance used 12 taxation ratios and 2 other important profitability ratios. These ratios are calculated using data from the financial statements of telecommunication sub sector business entities on the Indonesia Stock Exchange in 2018-2021. For conditions prior to the occurrence of Covid-19, financial report data for 2018 and 2019 are used and for conditions during the occurrence of Covid-19, financial report data for 2020-2021 are used. The ratio data obtained were tested for normality using the Kolmogorov-Smirnov and Shapiro-Wilk methods. Ratios whose data before and during the occurrence of Covid-19 are normally distributed will be subjected to a Paired Samples T Test to determine whether there is a significant difference in values before and during the occurrence of Covid-19. Meanwhile, for ratios whose data are not normally distributed, the Wilcoxon Signed Rank Test is carried out to determine whether there is a significant difference in values before the occurrence of Covid-19 and during the occurrence of Covid-19. This study shows that there are 2 different ratios, namely Gross Profit Margin (GPM) and Rent/Sales (S/P) in the period before and during the Covid-19 outbreak. While the other 12 ratios are Pretax Profit Margin (PPM), Net Profit Margin (NPM), Corporate Tax to Turn Over Ratio (CTTOR), Operating Profit Margin (OPM), Return on Equity (ROE), Return on Assets (ROA), Depreciation/Sales (P/P), Interest/Sales (B/P), VAT/Sales (PPN/P), Salary/Sales (G/P), Non Operating Income/Sales (PLU/P), and Non Operating Expense/Sales (BLU/P) did not show any difference between before and during the Covid-19 outbreak.

Authors: Amadea Audrey , Herdinata Christian 
Published: July 2022

Electronic Commerce (e-commerce) is a transaction of buying and selling goods or services carried out between companies, households, individuals, governments and communities or other organizations that is carried out online. Consumer confidence in using e-commerce has increased from year to year. This can be seen from the increasing number of visits and transaction value. The increase in the number of visits and transactions that occurred during the pandemic led to an increase in consumer complaints in the e-commerce sector. The increasing number of transactions made online requires e-commerce companies to pay attention to several factors that can affect customer repurchase intention. Repurchase intention is an important factor for a company to be able to increase sales. In increasing customer repurchase intention, there are several influential variables, namely e-trust and perceived value variables. This study aims to determine the effect of e-trust and perceived value on repurchase intention in e-commerce Shopee. The population of this study are Shopee users. The sample in this study was taken using purposive sampling method as many as 120 respondents. The criteria used in this study include: (1) Shopee users aged 17 to 65 years; (2) Consumers who have made purchases at Shopee at least 10 times in the last 1 year, from April 2021 to March 2022. This study uses multiple linear regression analysis techniques. The results showed that e-trust had a significant effect on repurchase intention. These results indicate that the higher the e-trust perceived by the customer, the more often the customer will repurchas e intention on Shopee's e-commerce. The results of this study also show that perceived value has a significant effect on repurchase intention in Shopee e-commerce. This significant effect shows that if the customer feels and gets the benefits in accordance with expectations, the customer will repurchase intention.

Children’s affiliation toward peers reflected in their picture drawings
Authors: Shinohara Asami , Narazaki Miyabi , Kobayashi Tessei 
Published: July 2022

AbstractPrevious studies have demonstrated that a picture-drawing task can be an indicator of the affiliation children have with their peers. When a child draws himself/herself along with a peer, the distance between them is assumed to represent the extent of the affiliation held by the child toward the peer: the shorter the distance is, the more affiliation the child has. However, some issues remain before the picture-drawing task is established as a way to measure children’s affiliation, including the possibility that the instructions might bias the children's responses (Thomas & Gray, 1992), and inconsistency over where to measure in the children’s drawings (e.g., Song et al., 2015). In this study, we focused on the above two issues and addressed whether the picture-drawing task can be used for measuring children’s affiliation toward peers. We conducted our study in Japanese nursery schools with 3- to 6-year-old children (N = 676), who drew pictures of themselves and a classmate. Teachers rated how much the children had played with the drawn peer. We found that the more a child had an affiliative relationship with a peer, the shorter the distance between the drawn child and peer was when measuring the closest points and the center between the two drawn figures. Our research sheds light on the validity of the picture-drawing task for measuring children’s affiliation.

Abstract
The curious Galactic features near G357.2−0.2 were observed with the MeerKAT radio interferometer array in the UHF and L bands (0.56–1.68 GHz). There are two possibly related features: a newly identified faint heart-shaped partial shell (the “heart”), and a series of previously known but now much better imaged narrow, curved features (the “worm”) interior to the heart. Polarized emission suggests that much of the emission is nonthermal and is embedded in a dense plasma. The filaments of the worm appear to be magnetic structures powered by embedded knots that are sites of particle acceleration. The morphology of the worm broadly resembles some known pulsar wind nebulae (PWNe) but there is no known pulsar or PWN which could be powering this structure. We also present eROSITA observations of the field; no part of the nebula is detected in X-rays, but the current limits do not preclude the existence of a pulsar/PWN of intermediate spin-down luminosity.
Modeling the Transport of Relativistic Solar Protons along a Heliospheric Current Sheet during Historic GLE Events

Published: July 2022

Abstract
There are many difficulties associated with forecasting high-energy solar particle events at Earth. One issue is understanding why some large solar eruptive events trigger ground-level enhancement (GLE) events and others do not. In this work we perform 3D test particle simulations of a set of historic GLEs to understand more about what causes these powerful events. Particular focus is given to studying how the heliospheric current sheet (HCS) affects high-energy proton transport through the heliosphere following an event. Analysis of ≥M7.0 flares between 1976 and 2020 shows that active regions located closer to the HCS (<10°) are more likely to be associated with a GLE event. We found that modeled GLE events where the source region was close to the HCS also led to increased heliospheric transport in longitude and higher count rates (when the Earth was located in the drift direction). In a model that does not include perpendicular diffusion associated with turbulence, the HCS is the dominant mechanism affecting heliospheric particle transport for GLE 42 and 69, and varying other parameters (e.g., a narrow, 10°, or wider, 60°, injection width) causes little change. Overall in our model, the HCS is relevant in 71% of our analyzed GLEs, and including it more accurately reproduces observed intensities near Earth. Our simulations enable us to produce model profiles at Earth that can be compared to existing observations by the GOES satellites and neutron monitors, as well as for use in developing future forecasting models.
Eliminating Primary Beam Effect in Foreground Subtraction of Neutral Hydrogen Intensity Mapping Survey with Deep Learning

Published: July 2022

Abstract
In neutral hydrogen (H i) intensity mapping (IM) survey, foreground contamination on cosmological signal is extremely severe, and systematic effects caused by radio telescopes further aggravate the difficulties in subtracting foreground. We investigate whether the deep-learning method, the 3D U-Net algorithm, can play a crucial role in foreground subtraction when considering the systematic effect caused by the telescope’s primary beam. We consider two beam models, i.e., the Gaussian beam and Cosine beam models. The traditional principal component analysis (PCA) method is employed as a preprocessing step for the U-Net method to reduce the map dynamic range. We find that in the case of the Gaussian beam, the PCA method can effectively clean the foreground. However, the PCA method cannot handle the systematic effect induced by the Cosine beam, and the additional U-Net method can improve the result significantly. To show how well the PCA and U-Net methods can recover the H i signal, we also derive the H i angular power spectrum and H i 2D power spectrum after performing foreground subtraction. It is found that in the case of Gaussian beam, the concordance with the original H i map using U-Net is better than that using PCA by 27.4%, and in the case of Cosine beam, the concordance using U-Net is better than that using PCA by 144.8%. Therefore, the U-Net–based foreground subtraction can efficiently eliminate the telescope primary beam effect and shed new light on recovering H i power spectrum for future H i IM experiments.

Abstract
We present the results of a search for core-collapse supernova neutrinos, using long-term KamLAND data from 2002 March 9 to 2020 April 25. We focus on the electron antineutrinos emitted from supernovae in the energy range of 1.8–111 MeV. Supernovae will make a neutrino event cluster with the duration of ∼10 s in the KamLAND data. We find no neutrino clusters and give the upper limit on the supernova rate to be 0.15 yr−1 with a 90% confidence level. The detectable range, which corresponds to a >95% detection probability, is 40–59 kpc and 65–81 kpc for core-collapse supernovae and failed core-collapse supernovae, respectively. This paper proposes to convert the supernova rate obtained by the neutrino observation to the Galactic star formation rate. Assuming a modified Salpeter-type initial mass function, the upper limit on the Galactic star formation rate is <(17.5–22.7) M
⊙ yr−1 with a 90% confidence level.
