Authors: Widyastuti Ratna , Izzah Abidatul , Kusuma Selvia Ferdiana
Published: March 2021

Mata pelajaran matematika merupakan mata pelajaran yang dipelajari peserta didik sejak usia dini. Berkembangnya materi matematika yang dipelajari mengiringi perkembangan kemampuan berfikir yang dimiliki siswa. Masalah yang terjadi saat ini adalah motivasi belajar peserta didik di tingkat Sekolah Dasar (SD) masih rendah dikarenakan matematika yang abstrak membuat banyak peserta didik menganggap matematika adalah mata pelajaran yang sulit. Guna menyelesaikan permasalahan tersebut maka dibuatlah Game edukasi bernama “Kangaroo Jump” yang berfokus pada materi Kelipatan Persekutuan Terkecil (KPK). Penelitian ini dikembangkan menggunakan 3 tahapan yaitu tahap penelitian awal, tahap pengembangan, dan tahap penilaian. Uji coba dilakukan kepada siswa-siswa di SD Negeri Dermo 1 Kota Kediri. Eksperimen dilakukan untuk mengetahui nilai yang di dapat siswa ketika mengerjakan soal matematika menggunakan Game edukasi dan tanpa Game edukasi. Selain itu juga ada penilaian angket yang berisi pertanyaan terkait pengalaman penggunaan media pembelajaran. Uji coba terhadap Game edukasi yang berjudul “Kangaroo Jump” menunjukkan bahwa penggunaan Game edukasi dapat meningkatkan motivasi belajar siswa pada mata pelajaran matematika sebesar 72,88 %.The development of the game "kangaroo jump" as a learning medium for the smallest alliance multiples to increase interest in learning AbstractMathematics is a subject that students learn from an early age. The development of the mathematics material being studied accompanies the development of students' thinking abilities. The problem that occurs at this time is the learning motivation of students at the elementary school level (SD) is still low because the abstract material in mathematics makes many students think mathematics is a difficult subject. In order to solve this problem, an educational Game called "Kangaroo Jump" was created which focused on the Least Common Multiple materials. This research was developed using 3 stages, namely the initial research stage, the development stage, and the assessment stage. The experiments will be carried out on students at SD Negeri Dermo 1 Kota Kediri. Experiments were carried out to determine the value that students get when working on math problems using educational Games and without educational Games. In addition, there is also a questionnaire assessment containing questions related to the experience of using learning media. The experiment of the educational Game entitled "Kangaroo Jump" shows that the use of educational games can increase student motivation in mathematics.

Published: March 2021

Objective. The study aimed to evaluate the effect of therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) in combination with melatonin on the dynamics of the quality of life (QOL), clinical and laboratory activity, and mixed anxiety– depressive disorder (MADD) in patients with ankylosing spondylitis (AS).

Materials and methods. The study involved 65 patients with AS and RTDS. Patients from Group I (n=32) were prescribed melatonin at a dose of 3 mg per day at night, 30–40 minutes before bedtime, in addition to standard AS therapy. Patients from Group II (n = 33) received standard therapy. 8 weeks after, the dynamics of QOL indicators, clinical and laboratory activity, and the severity of MADD in patients from both groups were evaluated.

Results. The application of melatonin in addition to standard therapy in patients with AS and MADD provided a statistically significant improvement in the functional and clinical-laboratory data (frequency and severity of anxiety and depression, pain syndrome indicators, ESR, CRP, integrative indicators of physical and psychological components of health).

Conclusion. The application of melatonin in complex therapy for patients with AS and MADD contributes to the improvement of clinical and laboratory parameters, psychoemotional state, and QOL of this category of patients.

Objective: the study aimed to reveal the daily periodicity of labor, the nature of melatonin metabolism, and the outcome of childbirth in women with a physiological and complicated pregnancy, depending on the sex of the fetus.

Materials and methods: to study the chronophysiological characteristics of birth outcomes depending on fetal sex, 1 980 birth histories and stories of newborns were analyzed. The neonates were born between January 1 and December 31, 2016, in a maternity ward of the Federal State Budgetary Educational Institution of Higher Education “RostGMU” of the Ministry of Health of Russia. Melatonin production was identified by the level of urinary excretion of 6-sulfatoxymelatonin (6-SM) (its main metabolite) examining the morning portion of the urine of women by the ELISA method (at 8 am 3 ml of urine were collected in Eppendorf tube).

Results: it was revealed that fetal sex modulated the activity of the central regulatory mechanisms responsible for the daily period functional processes in the female body and the initiation of labor. The largest number of spontaneous births by male fetuses occurred in the early evening before midnight when daily illumination was decreased, while the birth of girls was observed more often in the period from midnight to early morning. At the same time, mothers of boys had lower production of melatonin compared to that of girls’ mothers.

Conclusions. The peculiarities of labor and birth complications associated with the sex of the fetus were identified.

Authors: Sizyakina L. P. , Sergeeva A. I. , Andreeva I. I.
Published: March 2021

Objective. The study aimed to assess the dynamics of the systemic immune response in patients during mesotherapy with hyaluronic acid (HA).

Materials and methods. The observation group included 26 women who received the first-time mesocorrection with drugs based on hyaluronic acid (HA). Injections of low molecular weight HA were carried out according to standard methods in a course of 5 procedures with an interval of 14 days. The parameters of the innate and adaptive immune response were studied before and two weeks after the end of the course. The skin condition was assessed by dermatoscopy (Aramo Smart Lite 300, Southern Korea).

Results. The clinical effect of the course of procedures was reflected in the subjective improvement in the appearance. The improvement was confirmed by hardware analysis, which recorded an increase in hydration, a smoothing of the skin relief, and a decrease in the depth of wrinkles. At the end of the course, redistribution of lymphocyte populations towards natural killer cells and B-lymphocytes was revealed with a decrease in the total number of T cells. The antibody production of immunoglobulins of classes M and G was increased, the serum content of Ig A and IgE was reduced, the number of both T-effectors and T-lymphocytes with immunosuppressive activity increased. Changes in the neutrophil system were characterized by the inhibition of the production of reactive oxygen intermediates; the dynamics of the expression of Toll-like receptors by monocytes was ambiguous.

Conclusion. The results of the study confirmed the active involvement of the factors of innate and adaptive systemic response in the cosmetic effect, which manifested itself immediately after mesotherapy as systemic dysregulatory immune changes.

Authors: Mauch Chelsea E , Laws Rachel A , Prichard Ivanka , Maeder Anthony J , Wycherley Thomas P , Golley Rebecca K
Published: March 2021

Background

Parents juggling caregiving and paid employment encounter a range of barriers in providing healthy food to their families. Mobile apps have the potential to help parents in planning, purchasing, and preparing healthy family food. The utility and acceptability of apps for supporting parents are unknown. User perspectives of existing technology, such as commercially available apps, can guide the development of evidence-based apps in the future.

Objective

This study aims to determine the feasibility of existing commercially available apps for supporting the healthy food provision practices of working parents.

Methods

Working parents (N=133) were recruited via the web and completed a 10-item Capability, Opportunity, Motivation, and Behavior (COM-B) self-evaluation survey assessing their needs in relation to the provision of healthy family meals. A total of 5 apps were selected for testing, including a meal planning app, recipe app, recipe manager app, family organizer app, and barcode scanning app. Survey items were mapped to app features, with a subsample of parents (67/133, 50.4%) allocated 2 apps each to trial simultaneously over 4 weeks. A semistructured interview exploring app utility and acceptability and a web-based survey, including the System Usability Scale and the user version of the Mobile App Rating Scale, followed app testing. The interview data were analyzed using a theoretical thematic approach.

Results

Survey participants (N=133; mean age 34 years, SD 4 years) were mainly mothers (130/133, 97.7%) and partnered (122/133, 91.7%). Participants identified a need for healthy recipes (109/133, 82% agreed or strongly agreed) and time for food provision processes (107/133, 80.5%). Engagement quality was the lowest rated domain of the user version of the Mobile App Rating Scale across all 5 apps (mean score per app ranging from 3.0 to 3.7 out of a maximum of 5). The family organizer, requiring a high level of user input, was rated the lowest for usability (median 48, IQR 34-73). In the interviews, participants weighed the benefits of the apps (ie, time saving) against the effort involved in using them in determining their acceptability. Organization was a subtheme emerging from interviews, associated with the use of meal planners and shopping lists. Meal planners and shopping lists were used in time, while behavior was occurring.

Conclusions

Meal planning apps and features promoting organization present feasible, time-saving solutions to support healthy food provision practices. Attention must be paid to enhancing app automation and integration, as well as recipe and nutrition content, to ensure that apps do not add to the time burden of food provision and are supportive of healthy food provision behavior in time.

Published: March 2021

UNSTRUCTURED

Communicable diseases including COVID-19 pose a major threat to public health worldwide. To curb the spread of communicable diseases effectively, timely surveillance and prediction of the risk of pandemics are essential. The aim of this study is to analyze free and publicly available data to construct useful travel data records for network statistics other than common descriptive statistics. This study describes analytical findings of time-series plots and spatial-temporal maps to illustrate or visualize pandemic connectedness. We analyzed data retrieved from the web-based Collaborative Arrangement for the Prevention and Management of Public Health Events in Civil Aviation dashboard, which contains up-to-date and comprehensive meta-information on civil flights from 193 national governments in accordance with the airport, country, city, latitude, and the longitude of flight origin and the destination. We used the database to visualize pandemic connectedness through the workflow of travel data collection, network construction, data aggregation, travel statistics calculation, and visualization with time-series plots and spatial-temporal maps. We observed similar patterns in the time-series plots of worldwide daily flights from January to early-March of 2019 and 2020. A sharp reduction in the number of daily flights recorded in mid-March 2020 was likely related to large-scale air travel restrictions owing to the COVID-19 pandemic. The levels of connectedness between places are strong indicators of the risk of a pandemic. Since the initial reports of COVID-19 cases worldwide, a high network density and reciprocity in early-March 2020 served as early signals of the COVID-19 pandemic and were associated with the rapid increase in COVID-19 cases in mid-March 2020. The spatial-temporal map of connectedness in Europe on March 13, 2020, shows the highest level of connectedness among European countries, which reflected severe outbreaks of COVID-19 in late March and early April of 2020. As a quality control measure, we used the aggregated numbers of international flights from April to October 2020 to compare the number of international flights officially reported by the International Civil Aviation Organization with the data collected from the Collaborative Arrangement for the Prevention and Management of Public Health Events in Civil Aviation dashboard, and we observed high consistency between the 2 data sets. The flexible design of the database provides users access to network connectedness at different periods, places, and spatial levels through various network statistics calculation methods in accordance with their needs. The analysis can facilitate early recognition of the risk of a current communicable disease pandemic and newly emerging communicable diseases in the future.

BACKGROUND

Mobile health apps are important interventions that increase the scale and reach of prevention services, including HIV testing and prevention counseling, pre-exposure prophylaxis, condom distribution, and education, of which all are required to decrease HIV incidence rates. The use of these web-based apps as well as fully web-based intervention trials can be challenged by the need to remove fraudulent or duplicate entries and authenticate unique trial participants before randomization to protect the integrity of the sample and trial results. It is critical to ensure that the data collected through this modality are valid and reliable.

OBJECTIVE

The aim of this study is to discuss the electronic and manual authentication strategies for the iReach randomized controlled trial that were used to monitor and prevent fraudulent enrollment.

METHODS

iReach is a randomized controlled trial that focused on same-sex attracted, cisgender males (people assigned male at birth who identify as men) aged 13-18 years in the United States and on enrolling people of color and those in rural communities. The data were evaluated by identifying possible duplications in enrollment, identifying potentially fraudulent or ineligible participants through inconsistencies in the data collected at screening and survey data, and reviewing baseline completion times to avoid enrolling bots and those who did not complete the baseline questionnaire. Electronic systems flagged questionable enrollment. Additional manual reviews included the verification of age, IP addresses, email addresses, social media accounts, and completion times for surveys.

RESULTS

The electronic and manual strategies, including the integration of social media profiles, resulted in the identification and prevention of 624 cases of potential fraudulent, duplicative, or ineligible enrollment. A total of 79% (493/624) of the potentially fraudulent or ineligible cases were identified through electronic strategies, thereby reducing the burden of manual authentication for most cases. A case study with a scenario, resolution, and authentication strategy response was included.

CONCLUSIONS

As web-based trials are becoming more common, methods for handling suspicious enrollments that compromise data quality have become increasingly important for inclusion in protocols.

The Tulsa Race Massacre, White Supremacy and the Destruction of Black Wall Street
Authors: Ph. D., DPA Earnest N. Bracey,
Published: March 2021

Some might think about what happened in Tulsa, Oklahoma, in 1921, as unimportant; but the destruction of “Black Wall Street,” or the gem of the Black Greenwood District, was uncalled for. After all, segregation, white supremacy and white mob rule was the order of the day at this time. Furthermore, those who have tried to omit this incident from history or the historical record insult the intelligence of all Americans. But this “cover-up” is the repressive nature of sinister white supremacy. The destruction of “Black Wall Street” has been described as one of the most heinous crimes in American history. So can something like this racist incident happen again? Keep in mind that those heartless individuals who perpetuated the assault on the Black Greenwood community, obviously, didn’t care about the humanity of Black Tulsans. Of course, there was nothing dignified about this crime; therefore, what happened can never be rationalized or justified.Finally, as a nation, we must come to terms with this tragedy through reconciliation, atonement and reparations, without sweeping what happened under the rug, or pretending that this incident never occurred; or that it is not important, particularly during these polarizing times in our history.

Published: March 2021

Izradu najnovijih strategijskih dokumenta iz oblasti nacionalne bezbednosti i odbrane: Strategije nacionalne bezbednosti i Strategije odbrane, pratile su brojne polemike u redovima akademske i stručne javnosti. Ovaj rad nema nameru da se vrednosno određuje prema novoj Strategiji nacionalne bezbednosti, već pažnju primarno usmerava prema definisanim nacionalnim vrednostima i činiocima nacionalnih interesa Republike Srbije definisanih Strategijom nacionalne bezbednosti Republike Srbije. U radu se analiziraju svi delegirani činioci nacionalnih interesa sa aspekta njihove dostižnosti u svetlu dominantne realpolitike najznačajnijih aktera međunarodne politike i bezbednosti, kao i problemi pred kojima će se sprovodioci ovako delegiranih činilaca u bližoj i daljoj budućnosti suočavati. Imajući u vidu da se kao najizrazitiji problem prilikom ostvarenja ovako definisanih nacionalnih interesa legitimiše dihotomija između nacionalnog interesa koji se odnosi na očuvanje suverenosti, nezavisnosti i teritorijalne celovitosti i onog koji govori o evropskim integracijama i članstvu u Evropskoj uniji, naročita pažnja je posvećena formulisanju rešenja koje bi bilo na tragu „pomirenja“ ovih, naizgled antagonizujućih, interesa.

Authors: Курынцев С.В. , Шиганов И.Н.
Published: March 2021

Во второй части представлено продолжение обзора отечественных и зарубежных статей по теме лазерная сварка разнородных металлов, в частности титана с алюминием, алюминия с медью и других наиболее распространенных пар металлов. На основе анализа научных статей установлено, что при сварке титана и алюминия встык рационально смещать лазерный луч на алюминий (предел прочности 168–180 МПа), тогда как при сварке внахлест рационально воздействовать лазерным лучом со стороны титана. Смещение лазерного луча и режимы сварки существенно влияют на толщину ИМС, которую при сварке встык можно снизить до 2–6 мкм. При сварке алюминия и меди лазерный луч необходимо смещать на алюминий как при сварке внахлест, так и при сварке встык. Основным эксплуатационным свой­ством соединения алюминия и меди является электропроводность, которая напрямую зависит от толщины и состава ИМС. Также рассмотрены технологии сварки титана и магния, стали и меди и других пар металлов.

Published: March 2021

El artículo presenta los resultados de investigación del proyecto «Prácticas socioculturales de paz en Quibdó», que busca contribuir a la comprensión de la construcción de paz desde la cotidianidad de las comunidades de la capital del Chocó. Se plantea un análisis contextualizado de Quibdó frente a la construcción de paz desde las prácticas culturales. El enfoque es cualitativo, desde una metodología hermenéutico-fenomenológica. El análisis de la información se realizó a partir de la triangulación de información con fuentes primarias y secundarias a través de diez entrevistas semiestructuradas a profundidad. La codificación axial y categorial se realizó mediante el software ATLAS.ti, versión 7.5. Se encontró que el reconocimiento de la paz desde un enfoque territorial a partir de prácticas culturales cotidianas permite la resignificación de la memoria y la apropiación del entorno social, la memoria histórica y la no violencia. Se concluye que las prácticas socioculturales de paz permiten evidenciar la reivindicación de lo «afro» y lo «chocoano», reconociendo la necesidad de integrar aspectos como el género, lo étnico y el compromiso social en coexistencia con los otros.

Sebagai salah satu unsur utama dalam iklim, kajian mengenai suhu udara menarik untuk dilakukan. Oleh karena itu, penelitian ini dilakukan dengan melakukan pengolahan dan analisis data suhu udara permukaan kaitannya dengan kelembapan udara, curah hujan, SOI, dan DMI di Pulau Jawa. Data 30 tahun terakhir diambil dari enam stasiun BMKG yang mewakili Jawa bagian barat, tengah, dan timur, yang kemudian dilakukan perhitungan berdasarkan rata-rata tahunan dan bulanan. Analisis korelasi dilakukan terhadap parameter kelembapan udara, intensitas curah hujan, dan indeks fenomena variabilitas iklim (ENSO dan IOD). Hasilnya didapatkan bahwa suhu udara tahunan menunjukkan adanya trend peningkatan selama 30 tahun. Fluktuasi suhu udara bulanan memiliki pola bimodial di semua stasiun dengan puncak berada di bulan Maret-Mei dan Oktober-Desember, sedangkan lembah berada pada bulan Desember-Februari dan Juni-Agustus. Korelasi antara suhu udara dengan kelembapan udara dan suhu udara dengan curah hujan sebagian besar bernilai negatif. Analisis dengan indeks fenomena variabilitas iklim menunjukkan bahwa fluktuasi suhu udara di Pulau Jawa tidak berkorelasi dengan ENSO (El Nino Southeast Oscillation), tetapi berkorelasi cukup kuat dengan IOD (Indian Ocean Dipole).

Authors: Putra Moch Ridho Alfikri Limandika , Mahardhika Galang Prihadi , Putro Hanson Prihantoro
Published: March 2021

Problem solving adalah salah satu kemampuan untuk memecahkan sebuah masalah. Baik itu permasalahan komputasi maupun permasalahan sehari-hari. Kemampuan ini dapat memberikan penggunanya untuk menyelesaikan masalah dalam bentuk apapun. Karena pentingnya kemampuan tersebut, maka harus diterapkan sedari dini saat masih dalam usia sekolah. Kemampuan problem solving jika ditanamkan sejak dini, akan sangat membantu siswa-siswi dalam hal menyelesaikan tugas-tugas yang diberikan. Namun tidak semudah yang dibayangkan, masih banyak siswa-siswi yang kurang menaruh perhatian lebih kepada kemampuan problem solving ini. Penyebabnya tidak lain adalah teknik pengajaran yang masih dianggap membosankan, ini menyebabkan rasa malas untuk mempelajari apalagi mendalami tentang problem solving. Salah satu pendekatan yang bisa digunakan untuk melatih kemampuan ini adalah pendekatan Computational Thinking. Pada penelitian ini penulis membuat sebuah game edukasi Computational Thinking berbasis Role Playing Game. Game ini dibuat dengan menggunanakan beberapa rancangan yaitu Game Design Document dan Hierarchy plus Input Process Output. Serta metode yang digunakan adalah metode Analyze, Design, Development, Implementation, Evaluation. Dalam penelitian ini penulis mengujikan langsung kepada para murid dan mendapatkan hasil yang sangat memuaskan. Game yang dibuat dapat membuat para murid menjadi lebih termotivasi untuk belajar mengenai kemampuan problem solving. Ini berdasarkan data yang di dapat melalui pembuatan kuisioner. Metode yang digunakan dalam pembuatan kuisioner adalah skala likert. Game yang dibuat mendapatkan respon yang sangat positif dari para murid dalam berbagai aspek. Sehingga menghasilkan kesimpulan bahwa game Role Playing Game ini telah layak untuk dijadikan sebagai media untuk memotivasi para murid dalam hal mempelajari serta menanamkan kemampuan problem solving yang baik sejak dini.

Este estudo discute as possibilidades de inclusão do ensino de história da indumentária brasileira nas aulas de artes visuais para turmas do Ensino Médio e dos anos finais do Ensino Fundamental. Para tanto, foi realizado levantamento de modo a oferecer um breve histórico dos estudos de indumentária e de moda, especialmente no Brasil. A partir deste panorama, foram apontadas possibilidades de pesquisa no campo da história da arte tomando a representação da indumentária como chave de leitura das imagens. As fontes visuais elencadas para sustentar a discussão foram as obras de artistas viajantes em visita ao Rio de Janeiro no início do século XIX.

Published: March 2021

The aim of this study is to identify the level of gap extended between management perceptions of clients’ expectations, and clients’ expectations for service quality dimensions in the Jordanian commercial banks. The study also investigates the impact of combined service quality dimensions (tangibility, reliability, responsiveness, assurance, empathy, and online services) on management’s and clients’ expectations. In order to achieve the objectives of the study, a quantitative study was conducted and a convenience sampling was taken by distributing questionnaires to commercial bank managements and clients during the period of 2018–2019. In total, the researchers had: 362 clients and 168 managers. The study findings were analyzed by using the statistical packages for social sciences (SPSS Statistics V22.0). After testing the hypotheses using various techniques, it was found that there is a difference between management perceptions of clients’ expectations and clients’ expectations of service quality dimensions (tangibility, reliability, responsiveness, assurance, empathy, and online services). Also, it found that combined service quality dimensions as independent variables have a significant impact on management perceptions of clients’ expectations and clients’ expectations of service quality dimensions as dependent variables.
The Forecasting of Groundwater Fluctuations using Time Series Analysis and Combination of Data-Driven Models

Published: March 2021

The Forecasting of Groundwater Fluctuations is a useful tool for
managing groundwater resources in the mining area. Water resources
management requires identifying potential periods for groundwater
drainage to prevent groundwater from entering the mine pit and imposing
high costs. In this research, Auto-Regressive Integrated Moving Average
(ARIMA) and Holt-Winters Exponential Smoothing (HWES) data-driven models
were used for short-term modeling of the groundwater fluctuations in a
piezometer around the Gohar Zamin Iron Ore Mine. For this purpose, 250
non-seasonal groundwater fluctuations data in the period 22-Nov-2018 to
29-Jul-2019, 200 data for modeling, and 50 data for prediction were
used. To take advantage of all the features of the two developed models,
the predictions are combined with different methods and specific
weights. The results show better accuracy for the ARIMA method between
the two short-term forecasts, while the HWES method requires less time
for modeling. Also, among all the predictions made, the highest accuracy
for the combined least-squares method is for forecasting the groundwater
fluctuations in the short-term. All the forecasts show a decrease in the
groundwater fluctuations, indicating pumping wells around the Gohar
Zamin Iron Ore Mine area.
STUDY OF THE GUT ENTEROTYPES IN SOME EGYPTIAN PATIENTS WITH REMITTING RELAPSING MULTIPLE SCLEROSIS

Published: March 2021

Background: Gut microbiota cluster into three enterotypes named the
Bacteroides, Prevotella and Ruminococcus. While each person’s microbial
“fingerprint” is unique, there are specific patterns seen in those
that are healthy and those that have specific illnesses. The aim of the
present study is to identify the enterotypes that are likely related to
Multiple Sclerosis Egyptian patients as well as their possible role in
the course of the disease. Subjects & Methods: Thirty patients with
remitting relapsing multiple sclerosis, who presented to the MS Clinic
of Alexandria University Hospital were enrolled in our study. These were
diagnosed according to according to McDonnald 2017 criteria. A cross
matching control group of 20 healthy subjects of similar age and sex
were included. Stool specimens were taken from each. Quantitative SYBR
Green Real-Time PCR was done for the identification and quantitation of
Bacteroides, Prevotella and Ruminococcus which constitute the core of
the three major enterotypes. Results: Enterotype 1 is the most common
enterotype detected in MS and control cases (80% versus 65%). For
Enterotype 3, it was not detected in any of the 20 control cases while
detected in multiple sclerosis case (16.7%). However, by comparing the
multiple sclerosis and control cases Enterotype 2 is significantly less
in multiple sclerosis than control (3.3% versus 35%). Conclusion:
Although Enterotype 2 is significantly less in multiple sclerosis
patients, collapsing the whole microbiome variations into dominant
enterotypes was not appropriate to identify disease association or to be
used as a disease biomarker.

Objective The My Baby’s Movements (MBM) trial aimed to evaluate the
impact on stillbirth rates of a multifaceted awareness package (MBM
intervention). Design Stepped-wedge cluster-randomised controlled trial.
Setting Twenty-seven maternity hospitals in Australia and New Zealand.
Population Women with a singleton pregnancy without major fetal anomaly
≥28 weeks’ gestation from August 2016-May 2019. Methods The MBM
intervention was implemented at randomly assigned time points with
sequential introduction into 8 clusters of 3-5 hospitals at four-monthly
intervals. The stillbirth rate was compared in the control and
intervention periods. Generalised linear mixed models controlled for
calendar time, clustering, and hospital effects. Outcome Measures
Stillbirth at ≥28 weeks’ gestation. Results There were 304,853 births
with 290,219 meeting inclusion criteria: 150,079 in control and 140,140
in intervention periods. The stillbirth rate during the intervention was
lower than the control period (2.2/1000 births versus 2.4, odds ratio
[OR] 0.91, 95% Confidence Intervals [CI] 0.78-1.06, p=0.22).
The decrease was larger across calendar time with 2.7/1000 in the first
18 months versus 2.0/1000 in the last 18 months (OR 0.74; 95% CI
0.63-0.86; p≤0.01). Following adjustment, stillbirth rates between the
control and intervention periods were not significantly different: (aOR
1.18, 95% CI 0.93-1.50; p=0.18). No increase in secondary outcomes,
including obstetric intervention or adverse neonatal outcome, was
evident. Conclusion The MBM intervention did not reduce stillbirths
beyond the downward trend over time, suggesting hospitals may have
implemented best practice in DFM management outside their randomisation
schedule. The role of interventions for raising awareness of DFM remains
unclear

In this paper, we discuss the Schur convexity, the Schur geometric convexity
and Schur harmonic convexity of the mixed mean of n variables involving
three parameters. As an application, we have established some inequalities
of the Ky Fan type related to the mixed mean of n variables, and the lower
bound inequality of Gini mean for n variables is given.
On nonsingularity and group invertibility of combinations of two group invertible matrices
Authors: Li Yu , Zuo Kezheng
Published: March 2021

Let A and B be two group invertible matrices, we study the rank, the
nonsingularity and the group invertibility of A-B, AA#-BB#, c1A + c2B,
c1A + c2B + c3AA#B where c1,c2 are nonzero complex numbers. Under some
special conditions, the necessary and sufficient conditions of c1A + c2B +
c3and c1A + c2B + c3+ c4BA to be nonsingular and group invertible are
presented, which generalized some related results of Ben?tez, Liu, Koliha
and Zuo [4, 17, 19, 25].

Published: March 2021

In this paper we obtain two known solutions of the problem of continuity of
contractive mappings at fixed point under alternative set of conditions;
these known solutions followed the first solution of Rhoades problem by Pant
in 1999. We show that these two solutions characterize completeness and we
also compare these with some recent solutions of the Rhoades problem.
