Published: April 2022

The factors that cause errors in navigation information during the operation of satellite navigation systems are considered. The errors due to multi-beam interference are investigated. Methods for errors compensating of a satellite navigation system, which make it possible to compensate the influence of disturbing factors, in particular, errors caused by radio signals reflected from obstacles, are presented. It is proposed to build models of reflected signals by means of evolutionary algorithms. In the process of the satellite navigation system functioning, a systematic component model of the reflected signal with parametric identification is used.

Harmonisasi Hukum Adat dan Hukum Agama dalam Perkawinan Adat Masyarakat Osing Banyuwangi
Authors: Wagianto Ramdan
Published: April 2022

This paper examines the harmonization between customary law and religious law in traditional marriages of the Banyuwangi osing community. The contribution of religious law to the existence of customary law is inseparable. With the theory of reception a contrario, a harmonization between the two will be known. The method used in this research is qualitative-descriptive. The approach used is fiqhiyyah rules. The harmonization of customary law and religious law in traditional Bangkat marriages in the Osing Banyuwangi community can be seen from the absence of conflict and intersection between of them so that this Bangkat marriage custom is classified into a urf khas and urf sahih. It’s called Urf khas, because this custom applies to the people of Osing and urf sahih because this custom is not contrary to the Shari'a. Bangkat customary marriages basically show advice and hopes in order to create a happy home life. The form of advice and hope can be seen from the symbols of the tools used at customary times, namely sewur which means someone when choosing a mate, which in Islam is stated to be seen from the side of kafa'ah (wealth, lineage, beauty, and religion). Then the obligation to provide a place to live and provide a living by the husband to his wife as mentioned in Islam, in the Bangkat custom is reflected in the cingkek, bokor, bantal and kloso. Islam also teaches to give some of their sustenance to charity, in the Bangkat custom it is reflected in the coins from the kosekan that are given to people who are present at the Bangkat wedding ceremony.

BANKS AND INSURANCE COMPANIES IN THE FINANCIAL SERVICES MARKET
Authors: Zemlyacheva Olga Andreevna
Published: April 2022

Foreign and domestic practice indicates that banks and insurance companies are key participants in the global, international and national financial markets and their segments, including financial services markets.

The analysis of the world economy, the services market, financial services, and the banking and insurance markets for 2009–2016 confirmed the conclusions that banks and insurers are the drivers of the global economic and financial system, as well as key components of the services and financial services markets. The same can be said about economically developed countries, where banking and insurance services account for up to 10% of national GDP.
Additionally, trends in the development of foreign markets for banking and insurance services are studied, with an emphasis on the markets of economically developed countries
ESTABLISHMENT OF LABOR RELATIONS IN THE DIGITAL ECONOMY: REALITIES AND PERSPECTIVES
Authors: Yachmeneva Valentina Maryanovna , Yachmenev Evgeniy Fedorovich
Published: April 2022

The regulation of labor relations is in the plane of labor law, but in the context of a pandemic, non-traditional labor relations and informal forms of employment have arisen, which are not provided for by any current legal document.
The aim of the study is to analyze labor relations and informal forms of employment of the population during a pandemic and post-pandemic period. The analysis of skills demanded by the labor market was carried out. It has been established that skills have a certain life cycle, hard skills are characterized by a short life cycle, soft skills — a long one. The digitalization of the economy requires from society the advanced development of competencies that are in demand by the Industry 4.0 ecosystem. In conditions of spatial and resource constraints (pandemic), non-standard forms of employment appear in the labor market (temporary (fixed-term, seasonal) employment, part-time work (call work), temporary agency work and other multilateral labor relations, as well as disguised labor relationships and dependent self-employment). Research has shown that the reasons for the emergence of new labor relations were: insufficient regulatory support; dynamically changing external environment; change in the technological structure; the emergence of precarious forms of employment and growing informal employment; short life cycle of formed professional competencies and job loss due to the COVID-19 pandemic. The development of the gig economy contributes to the development of the freelance market, and it, in turn, affects the development of non-standard forms of employment in the labor market.

Effect of Critical Thinking-infused Paragraph Writing Instruction on University First-year Students’ Argumentative Paragraphs Writing Performance
Authors: Bekele Getachew , Olana Tamiru , Ali Sherif
Published: April 2022

The purpose of this study was to investigate the effect of critical thinking-infused paragraph writing instruction on university first-year students’ argumentative paragraph writing performance. In order to achieve the purpose, two randomly selected intact classes with 31 and 32 participants were involved in the study as a non-treatment group and a treatment group respectively. The treatment group was provided with critical thinking-infused paragraph writing instruction, but the non-treatment group received a conventional paragraph writing instruction. The embedded design was employed in the study since it was mainly conducted using quantitative data gathered through tests before and after the intervention, and a semi-structured interview was also employed to gather data about the treatment from some randomly selected participants in the treatment group. The quantitative data were entered into SPSS version 20 and analysed using descriptive statistics and one-way between groups ANCOVA while the qualitative data were analysed by narrating the reactions of the randomly selected participants using words. The one-way ANCOVA results for argumentative paragraph writing performance scores F (1, 60) = 106.555, p = 0.000, partial Eta squared = 0.640) showed that there was statistically a significant difference between the non-treatment and the treatment groups in their argumentative paragraph writing performance due to the intervention (Critical thinking-infused paragraph writing instruction). The interview analysis result also revealed that the intervention guided participants in the treatment group to perform better while they wrote argumentative paragraphs. Thus, it was recommended that EFL instructors, curriculum (syllabus) designers, and material developers need to integrate critical thinking instruction into argumentative paragraph writing lessons in order to promote first-year students’ argumentative paragraph writing performance.

Authors: Luvanda Maureen K.
Published: April 2022

Hati hii imetayarishwa kushughulikia maswala ya ustawi wa mifugo nchini Kenya na kuongezeka kwa ujuzi wa wafanyikazi wa mstari wa mbele kuhusiana na swala la viwango na sheria zinazoongoza ustawi wa wanyama. Lengo kuu lilikuwa kutathmini vipengele vya utunzaji wa wanyama, matibabu na ujuzi wa ustawi wa wanyama miongoni mwa wakulima nchini Kenya. Tuligundua ya kwamba wakulima wengi hawaelewi kimsingi ustawi wa wanyama kwa kuwa wengi wao hawajapata mafunzo maalum na wengi wao hawajui sheria zilizopo kuhusu mada hiyo. Wadau wengine walitathminiwa pia kwa madhumuni ya kulinganisha na madaktari wa mifugo na kama ilivyotarajiwa walikuwa na ujuzi zaidi kuhusu ustawi wa wanyama na desturi zinazoikuza. Hata hivyo, kadhaa walionelea kwamba serikali haikuweka juhudi za kutosha katika kukuza ufahamu wa umma au hata kuhamasisha jamii dhidi ya ukatili wa wanyama. Kulingana na maelezo yaliyopatikana, hati hii iliundwa ili kutoa suluhisho ya vitendo linapohusu swala la kuongeza ustawi wa wanyama nchini Kenya. Mapendekezo haya ni pamoja na kuishinikiza serikali kuanzisha sera madhubuti dhidi ya ukatili wa wanyama, kuwahimiza maafisa wa sheria kutekeleza sheria za sasa kwa kutumia mifumo ambayo tayari iko na kuhimiza mazungumzo ya jamii na ushiriki wa moja kwa moja wa watu walio mstari wa mbele.

Hipertrofia lipomatosa epicárdica: la entidad desconocida. Diagnóstico y tratamiento
Authors: Díaz Caraballo Eva , Eulalia Jiménez María , Giovanna Uribe Nancy , Moreno Sara , Balaguer Javier
Published: April 2022

La hipertrofia lipomatosa cardíaca (HLC) o lipomatosis cordis es una patología cardíaca no bien conocida en la que persisten dificultades en su diagnóstico y manejo terapéutico. Causada por la hiperplasia de lipocitos, se caracteriza por la acumulación de tejido adiposo no encapsulado, siendo su localización más frecuente en el septo interauricular, y más desconocida a nivel epicárdico. Con un diagnóstico inicial erróneo con ecocardiografía transtorácica de derrame pericárdico en la mayor parte de los escasos casos sintomáticos descritos de HLC epicárdica en la literatura médica, las nuevas técnicas de imagen como la tomografía computerizada (TC) y cardiorresonancia magnética (cardio-RM) permiten caracterizar el tejido con alta sensibilidad y especificidad.

Lajmska borelioza (LB) je bolest koju u Europi najčešće uzrokuju borelije kompleksa Borrelia burgdorferi sensu lato, dok je u Sjevernoj Americi jedino patogena B.burgdorferi sensu stricto. Kliničke manifestacije LB su polimorfne. Postavljanje dijagnoze temelji se na kliničkoj slici i epidemiološkim podacima o vjerojatnosti kontakta s krpeljima uz primjenu mikrobiološke dijagnostike. Najčešća je rutinska dijagnostika serologija za određivanje i praćenje dinamike specifičnih protutijela IgM i IgG. Nakon primarnog testiranja, rezultate je potrebno potvrditi dodatnim testom visoke specifičnosti. U područjima visoke prevalencije, specifičnost rezultata visoko osjetljivog i specifičnog testa nije obvezno dodatno potvrđivati. I pozitivni i negativni nalazi moraju se interpretirati klinički. Serološka dijagnostika predstavlja dobrobit za prepoznavanje i liječenje bolesnika samo ako se rezultati interpretiraju temeljem poznavanja patogeneze, kliničke slike i imunosnog odgovora kao i karakteristika korištenog testa. Karakteristike samih borelija i prezentacije antigena, izbjegavanje imunosnog odgovora, dostupnost različitih testova kao i Interneta predstavljaju zamke, posebno ako se slijede neprovjerene informacije.

Pandemi Corona Virus Disease (COVID-19) merupakan salah satu ancaman kesehatan terbesar di dunia. Mencuci tangan merupakan salah satu cara untuk mencegah penularan penyakit ini. Namun, sering mencuci tangan dapat menyebabkan kulit kering. Hand cream merupakan salah satu produk pilihan untuk mengatasi masalah ini. Penelitian ini bertujuan untuk menganalisis karakteristik fisik dan tingkat kesukaan konsumen (hedonik) terhadap produk hand cream yang mengandung minyak melati 1% (HC-1) dan hand cream tanpa minyak melati (HC-0). Parameter karakteristik fisik yang diamati meliputi organoleptik, homogenitas visual, pH, dan daya sebar. Organoleptik dan homogenitas dianalisis secara deskriptif. Sedangkan pH dan daya sebar dianalisis menggunakan analisis statistik Mann-Whitney. Pada uji hedonik parameter yang dinilai adalah aroma, warna, dan tekstur. Data uji hedonik dianalisis menggunakan analisis statistik Mann-Whitney. Hasil uji karakteristik fisik menunjukkan bahwa HC-1 memiliki aroma melati sedangkan HC-0 tidak memiliki aroma. HC-1 dan HC-0 memiliki warna putih. Kedua formula juga terlihat homogen secara visual. HC-1 memiliki nilai pH 5,69 ± 0,01, sedangkan HC-0 6,04 ± 0,01. Nilai-nilai ini berbeda secara statistik. HC-1 dan HC-0 memiliki nilai daya sebar yang sama, sekitar 3,7 cm. Berdasarkan uji hedonik, penilaian panelis terhadap HC-1 untuk parameter aroma lebih tinggi dibandingkan dengan HC-0. Sedangkan untuk parameter warna dan tekstur tidak ada perbedaan yang signifikan. Kesimpulan dari penelitian ini adalah penambahan 1% minyak melati pada hand cream mempengaruhi aroma, pH, dan tingkat kesukaan konsumen (untuk parameter aroma).

Authors: Mustafayeva A. H.
Published: April 2022

The purpose of this work is to analyze the daily levels of blood pressure and heart rate variability in patients with signs of metabolic syndrome.

Materials and methods. In the period from 2013 to 2016, 364 patients of the age from 20 to 80 (200 men and 164 women) with newly diagnosed MS were prospectively examined. Daily ECG monitoring applying the Holter method was performed with the help of Cardiomax system (USA), in compliance with the standard method for diagnosing paroxysmal forms of arrhythmia and stress and painless forms of ischemia. V2, V5 and avF derivations were registered.

Results. The maximum daily average values of systolic and diastolic blood pressure recorded in patients of the 61 to 80 age group were the following: systolic BP - 156.9±3.5 mm Hg diastolic BP - 96.2±4.1 mm Hg The heart rate variability analysis showed that the value of circadian index in patients of the third age group was significantly lower (1.14±0.12) than in patients of the first and second groups, amounting to respectively 1.2±0.11 and 1.19±0.13. Besides, we noticed an increase of daytime and night Ps levels (up to 79.0±9.0 and 66.5±4.1 BPM) in patients of the second group compared to the first group, where the values of these indicators were respectively 75.4±8.4 and 60.6±6.2 BPM. Heart rate variability at different times of day depending on age indicate adverse changes in the autonomic regulation of cardiac activity alongside with increasing the age of patients with MS. With the increase of age in patients with Ms, the rate of detecting cardiovascular complications risk factors steadily grows.

Conclusion. It is necessary to conduct dynamic monitoring for patients with symptoms of metabolic syndrome in order to identify signs of cardiovascular system state disturbances, blood pressure and heart rate in particular.

Aim. The aim of this randomized clinic trial was to study 5-year follow up of morbidity and mortality in patients with acute coronary syndrome after conducted multivessel percutaneous transluminal coronary angioplasty (PTCA).

Material and methods. The trial was carried out in two groups with EF 35% for assessment of acute coronary syndrome impact to myocardial revascularization. 742 patients were included to the trial. All patients were undergone coronary angiography admitted during 6 hours after MI and followed through PTCA. 5 year follow-up of morbidity was investigated on these patients considering an initial EF.

Results. 129 patients had got EF indices lower than 35%. Only 122 patients (94%) among these ones completed the 5 year follow up. 613 patients had got EF with initial indices higher than 35%. Average age of patients with EF 35% - 55,8 year (SD 10-17). 110 patients (90,2%) with EF 35% were men. 12 (9,8%) women were in the group with EF35%. Only 577 (93,8%) of them completed the follow up. The estimation of morbidity and mortality were done in divided groups by EF for both sex. Also there were investigated and compared the causes of death in both groups.

Conclusion. EF was determined as an important factor influenced morbidity and mortality in patients after PTCA.

Authors: Babayeva N. Z.
Published: April 2022

The aim of this study was to investigate the heart and common carotid arteries (CCA) morphological and functional condition and the lipid spectrum in patients with arterial hypertension (AH) and type 2 diabetes mellitus (DM-2).

Material and methods. The study included 144 patients with varying degrees of AH, 103 had AH without DM-2 (AH subgroup) and 41 patients with AH and DM-2 (AH+DM-2 subgroup). In all investigated patients the blood plasma lipid profile, echocardiographic examination of the heart and ultrasound Doppler examination of the CCA were carried out.

The results. Significant differences between the AH and AH+DM-2 subgroups were discovered, which confirmed the significant effect of DM-2 on various parameters of the cardiovascular system. The lipid profile in the above mentioned subgroups has not significant differences, but some separated indices (TG, VLDL) in the AH+DM-2 subgroup were comparatively higher and HDL level lower comparing to AH subgroup. Marked changes in echocardiographic parameters, such as lowering of left ventricle (LV) ejection fraction (EF), significant increase of interventricular septum and LV posterior wall thickness, high frequency of LV hypertrophy detection, diastolic dysfunction, diffuse hypokinesis and dilatation of the heart cavities in the AH+DM-2 subgroup were confirmed. A significant rise of CCA intima-media thickness also was found in the AH+DM-2 in comparison with AH subgroup, which proved the essential role of comorbidity of AH and DM-2 in the heart and vessels remodeling.

The conclusion. The results of the study confirm the role and significance of comorbidity of AH with DM-2 in the development of the cardiovascular system pathological changes.

Myrtus communis L is one of the medicinal plant being used in Ethno pharmacological domain in Algeria and many other parts of the world. The present study deals with the evaluation of the in vitro antioxidant and anti-inflammatory activities of leaf extract of M. communis L by using free radical scavenging assay DPPH, Ferric Reducing Antioxidant Potential FRAP, ß-Carotene bleaching, and denaturation test of the (BSA) protein. The chemicals compositions were carried out by Gas chromatography-mass spectrometry (GC/MS). The major constituents of essentials oil were D-Limonene (30.45%), α-Pinene (22.11%), 2,6-Octadien-1-ol, 3.7-dimethyl-, acetate (6.29%) respectively. The result showed that the highest antioxidant capacity was exhibited with IC50 = 45.76 μg/ml. A stronger ß carotene bleaching inhibition capacity is observed. The EO exhibited also remarkable activity to reduce iron (Fe), reflected by the optical densities (0,930) obtained at concentration (60 μg/ml). Leaf extracts of myrtle revealed significant anti-inflammatory activity. The results showed that the percentage inhibition of BSA denaturation (0.2%) is proportional to the different concentrations of the EO, where the highest value was recorded at the 200 μg/ml, resulted at approximately (64.08%).The Biological activities of this medicinal plant found so far may direct its use towards as prebiotic in food formulation, additives foods and eth-nopharmacological domain in the long run.
