Multi-Lingual Mobile Application to Improve the Pharmaceutical Care of Patients in Ethiopia
Authors: Bayissa Mesfin Workineh , Techane Dejene
Published: January 2023

Delivering essential information for patients concerning medication they’re taking is vital and improves healthcare services. Due to heavy burdens in every pharmacy, patients in Ethiopia do not get proper advice about the medicinal drugs they’re taking from the pharmacist. Moreover, it is far tough to recognize and interpret the various written instruction on remedy labels or package deal leaflet while not heaving the domain knowledge. As Ethiopia is an importer of many medicinal drugs from abroad, very often the package leaflets are not written in the local language. Therefore, due to language barrier, most of the patients cannot comprehend the information on medication labels and on package leaflet. In this regards most patients purchase the medication without a proper understanding of how to use the medication. This necessitates a technological based solution which serves patients in their language when they want an advice. This study demonstrates the design and implementation of a mobile-based solution to minimize such challenges and improve patient access to the medicinal drugs information. The requirements of the proposed system gathered using interview from pharmacist, doctors, technical expert, and client. Finally, a mobile application prototype is developed and evaluated for its effectiveness.

Pinah Laman: The Construction of Religious and Ethnic Identity Within the Mentuka Dayak of West Kalimantan
Authors: Yuswanto Felisitas , Aryani Sekar Ayu , Muttaqin Ahmad
Published: January 2023

For the Mentuka Dayak tribe, Pinah Laman is a change in ethnic and religious identity. Pinah Laman in the Mentuka Dayak community is perceived as a cultural space for community members who convert to a particular religion. Generally, religious conversion occurs in this society from Catholicism to Islam. The new identity is given by the term ‘Sinan.’ But on the other hand, the Sinan identity has its own meaning. Sinan is a new identity given to those who have converted to another religion. Because of this Pinah Laman custom, they do not get their tribal rights, such as: performing the Mentuka Dayak traditional ceremonies. This article aims to explore the construction of a new identity from the construction process of religious identity, which involves custom. In addition, this article also explains the form of religious identity construction that occurs among the Mentuka Dayak tribe and the new converts who experience it. Religious conversion is inseparable from the driving factors for the emergence of a new identity and the implications of constructing a new identity due to the conversion process. This article was compiled from the results of research using the ethnographic method. The results of this research show that Pinah Laman is a conversion process of a Christian or Catholic Dayak to Islam. This impacts the social sanctions one receives from one’s social group. For the Mentuka Dayak people, when someone decides to change his religion, he must be willing to give up his Dayak ethnicity. One of the social effects felt by a new convert in the Dayak tribe is that he will be given a nickname or term ‘Sinan.’ Based on the results of this research, the term Sinan has a negative connotation. This is because those who change their religion are ultimately not given the freedom to practice Dayak customs as usual.

Published: January 2023

Enzymes are the substances that speeds up a chemical reaction suitable for green chemistry and can be used to achieve ecological industrial processing in order to reduce the effects of industrial pollution. Microbiological degradation of pelt waste is amongst the permanent concerns of tanners. Several enzymes have been used in the leather industry to substitute the conventional process, mainly proteases. The objectives of this study were to isolate and identify bacteria which produced protease enzyme from tannery solid waste. The selected bacterial strains showed increased protease biosynthesis capacity, which had a significant hydrolytic action on pelt waste. The results obtained in this study demonstrated the ability of strains belonging to the Bacillus genus to synthesize increased amounts of proteolytic enzymes and to degrade pelt waste, as well as the possibility of using these microorganisms as a source of protease in various biotechnological processes.

Authors: Simion Demetra , Gaidău Carmen , Păun Gabriela
Published: January 2023

The influence of a classical surfactant – palmitoyl-glycylglycine and bola amphiphilic – demecarium bromide upon the elastin membrane preparation and separation mechanism of turmeric from aqueous solutions was studied by: UV-VIS spectroscopy, scanning electron microscopy, dynamic light scattering and separation rates. The tensile strength and hydrophobic property were improved by introducing a surfactant (classic or bola). In this research the influence of surfactants upon the microporous structure and retention of turmeric from aqueous solutions was studied. The biomembranes were produced by a casting-solvent evaporation technique. The elastin powder was dissolved in a water-acetic acid (70:30 v/v) solution with and without plasticizer: glycerol and surfactant (classic or bola), constant continuous stirring for 5-7 hrs. at 60°C, then degassed the solution for 2 hrs. The solution was poured and afterwards maintained in the oven at 45-55°C for 5-8 hrs. Ecological biomembranes are obtained from a biodegradable biopolymer – elastin, and can be used successfully in removing turmeric from wastewaters.

Viscous stability criterion in a thin layer on a rotating sphere is studied. The case when the fluid is inviscid was explained by Watson in 1981, the work was motivated by the idea suggested by Drazin and Ried in their celebrated text "Hydrodynamic Stability"; here  we will investigate the model worked out by B. Sherif and C. Jones in the year 2005, and show the necessary condition for instability which depends on the energy that is provided by the shear motion of the fluid in spherical thin layer.
The application of directional derivative in the design of animation characters and background elements
Authors: Zhang Qing
Published: January 2023

In the process of designing animation characters and background elements, there may be a high degree of visual blur, resulting in a strong sense of picture distortion, and it is easy to expose the incomplete picture. Accordingly, this paper proposes to use directional derivatives to deal with animation-like visual problems. This method is based on the theoretical basis of directional derivatives, combined with the current mathematical methods of animation character and background element design, and defines the important role of directional derivatives in animation and background design, and more effectively enhances the visual results of animation characters. In the research of clarity and distortion, this paper uses directional derivative derivation as the cutting-in method to test the algorithm for visual simulation and restoration of animated characters and background elements so that the algorithm can be used for each animation character and background element. The defect point is calculated, and the clarity and self-healing ability of the video itself are improved by the influence of the mathematical parameters of the surrounding known points on itself and the key variable of the directional derivative in the field. The results show that the directional derivative can play a role in promoting sublimation in the design of animated characters and background elements.
A design of the lightweight key management system for multi-level embedded devices
Authors: Wang Lei , Li Yalong , Tian Xinyuan , Mo Deyun
Published: January 2023

Embedded devices often face security risks such as device loss, cracking, key disclosure and side-channel attacks. Owing to the relative meagreness characterising the availability of computing as well as storage resources, it might be said that embedded devices themselves have limited resources, and traditional key management solutions are thus not fully suitable for embedded device usage scenarios. In addition, embedded device key management also necessitates consideration of the dynamic changes of devices, such as device joining and withdrawal, and blacklist management and control. A lightweight key management scheme is proposed for multi-layer embedded devices, and the management and control problems of the device blacklist library are analysed and an optimisation scheme is proposed. Finally, the scheme of this paper is analysed in detail based on the aspects of security and resource overhead. Compared with the traditional key management scheme, the scheme designed in this paper can be better applied to the communication of embedded devices to meet the security requirements of embedded systems.

Published: January 2023

Diabetic retinopathy is the leading cause of visual loss and blindness in working-age adults and represents the most common microvascular complication of diabetes mellitus.

The current research assesses the retinal arterioles status in healthy volunteers and diabetic patients, in order to detect early retinal changes by using adaptive optics ophthalmoscopy (AOO), a cutting edge, noninvasive imaging technique. Our patients were evaluated between 2021-2022 in the Retina Clinic Bucharest, Romania. All of them underwent a complete ophthalmologic examination. By using rtx1™ adaptive optics retinal camera (Imagine Eyes, Orsay, France) together with the manufacturer’s software (AO detect artery, Imagine Eyes, France), several vascular parameters of the retinal arteriole were calculated, including wall to lumen ratio (WLR), vessel diameter (VD), lumen diameter (LD), mean wall thickness (WT) and cross-sectional area of the vascular wall (WCSA).

All five studied vascular parameters were found to have higher values in diabetic patients, when compared to healthy volunteers. The differences were statistically significant for WT, WLR and WCSA (p values under 0.05).

Adaptive optics ophthalmoscopy represents a cutting-edge technique, opening a new era in the medical retina field. It provides useful data regarding the retinal vascular status, in a non-invasive manner, being a promising tool in the diagnosis, staging and follow-up of diabetic retinal disease.

Authors: Cosmin Preda , Leonard Gurgas
Published: January 2023

Bladder cancer is the most common malignancy involving the urinary system, urothelial carcinoma of the upper tract is a rare subgroup of urothelial cancers with poor prognosis, being the most common histological type of bladder cancer (approximately 90%), manifesting as invasion of the basal membrane (or deeper) by neoplastic cells of urothelial origin.

This type of carcinoma is more common in men than women, with a male to female ratio of 2:1, with men being 3 to 4 times more likely to develop bladder cancer than women.

The present study is a retrospective study including 174 patients in the Urology Clinic of Constanta County St. Apostle Andrew Emergency Hospital in the period 2016-2020. Patients were divided into 2 groups: Group A and Group B. Group A includes patients with anatomopathologically confirmed diagnosis of urothelial carcinoma, while in Group B are patients who do not present a diagnosis of urothelial carcinomas.

In this study the influence of environmental factors on the occurrence of urothelial carcinomas was compared in order to draw conclusions on the occurrence and development of these types of neoplasms.
Sacrificial Anode Cathodic Protection System Modelling Using Direct Boundary Element Method
Authors: Mujezinović Adnan , Martinez Sanja
Published: January 2023

Cathodic protection system is commonly employed approach for the protection of the metallic infrastructure placed in electrolyte against corrosion. Adequate design of the cathodic protection system requires the determination of electrical potential and current density distribution on the protected object surface that meets the defined criteria. In this paper, the application of the direct boundary element method in conjunction with Newton-Raphson method was considered for the calculation of the electric potential and current density distribution on the surface of the cathodically protected underground object. The considered method was applied on the sacrificial anode cathodic protection system of the underground pipeline. The non-linear boundary conditions of the electrode surfaces of the cathodic protection system are taken into account. The method was used to determine the current density and electric potential distribution on the external wall of the protected pipeline.
Features of Self-Taxation as a Form of Local Budget Revenues
Authors: Babin Igor Ivanovych
Published: January 2023

The aim of the article is to reveal the features of self-taxation as an independent form of local budget revenues. There is no consensus among domestic and foreign scholars on understanding the nature, place, and role of self-taxation in the system of income sources of territorial communities. Another problem is the fact that today in Ukraine there is virtually no legislative regulation of this financial and legal institution. The research methodology is based on formal-dogmatic, comparative-legal, systemic-structural and other scientific methods. It is substantiated that self-taxation is an independent type of mandatory payment, which is non-tax in nature and is used to address issues of local importance, the population at a general meeting or local referendum independently determines its size, procedure for introduction, and use.
On the Influence of the Nugget Effect on the Efficiency of Magnetometric Soil Surface Screening
Authors: Zawadzki Jarosław , Fabijańczyk Piotr
Published: January 2023

The paper presents selected aspects of calculations and modelling of variograms from measurements of soil surface magnetic susceptibility for rapid screening of surface soil contamination with Technogenic Magnetic Particles (TMP). In particular, the methodology of variogram analysis in the case of multiple magnetometric measurements in one measurement location with the use of the MS2D Bartington sensor was discussed. A new approach to analysing such measurements was proposed that allows determining and using the nugget effect from standard, already existing measurements. This is of key importance for the quality of spatial analyses, and thus the screening results obtained by means of field magnetometry. In the paper, it was shown, step by step, that averaging the measurements performed at one measurement point during the calculation of the empirical variograms does not result in the loss of information on spatial variability in the microscale. As it was calculated non-averaged measurements were characterised by the nugget-to-sill ratio of about 96 % which was much higher than in the case of averaged measurements (close to 0 %). A range of correlation was similar in both cases and was equal to about 300 m - 400 m. The local variogram revealed a range of correlation of about 80 cm. As a result, the screening results are more reliable than is the case with the traditional procedure. An additional advantage of the work was the performance of all calculations in free R software.
The coronavirus and center-peripheral relations in the economies of the European Union
Authors: Jasiecki Krzysztof
Published: January 2023

From the perspective of the diversity of capitalism and that of economic sociology, the article deals with the issue of center-peripheral relations as one of the key dimensions of economic diversification that determines the development opportunities of the European Union. The collapse of the convergence processes during the 2008–2010 financial crisis revealed the separateness of development trajectories of various countries and geographical regions of the EU. Without reversing this phenomenon and working out new mechanisms of development convergence and institutions supporting them, the process of European integration will enter further structural crises that may lead to the disintegration of the EU. Various classifications of the core and of the peripheries of the euro area are characterized, within which several types of countries are identified with different economic characteristics (countries of the Northern core and of the Southern peripheries of the euro area, different types of peripheries in Southern Europe and in Central and Eastern Europe, the internal core and the external core or the outer core, and the internal peripheries and the external peripheries, as well as the super-peripheries including candidates or potential candidates to join the EU). The COVID-19 crisis has an asymmetric impact on the economic situation of the Member States. As with other crises, this impact will be the result of the interconnection of the prior state of economies, structural differences in growth patterns, and responses to new challenges brought about by the pandemic. Also, the consequences of the pandemic for the reconfiguration of center-peripheral relations in the EU are discussed, with a particular focus on the CEE.

Introduction. Because of the increasing interest in the study of saliva, many methods have become available that can allow us to perform multiple and rapid analyzes of the composition of salivary secretion using advanced techniques of nanotechnology and fluid micro- engineering. The objectives of our study were to identify immunoglobulin levels variations with age.

Materials and methods. We conducted an analysis to check the correlation between saliva and plasma parameters on 24 patients. The study population was divided into 2 groups based on age, with a cut-off at 35 years. The differences on the variables between two groups were evaluated by TTEST and CORREL.

Results. Total plasma calcium, as well as ionic calcium have increased values in group 2, the increase being statistically significant (p =0.04) only for ionic calcium. Significant correlation of plasma and salivary values in the case of IgA / IgG ratio, and also a significant correlation of salivary and plasma concentrations for IgG were identified in our study.

Conclusions. The correlation between plasma and salivary parameters is closely related to age and these can be used as markers for diagnosis and evaluation of various pathologies. Also, regarding women, salivary calcium and phosphate concentrations increase with age showing peak values around menopause.
A Clinical Approach of Lupus Nephritis Associated with Catastrophic Antiphospholipid - Antibody Syndrome - Review and Case Report
Authors: Stoian Marilena , Scarlat Gabriel , Șeitan Silviu , Procopiescu Bianca
Published: January 2023

Glomerulonephritis is a major cause of morbidity in systemic lupus erythematosus (SLE). In fact, immune complex formation and deposition in the kidney results in intraglomerular inflammation with recruitment of leukocytes and activation and proliferation of resident renal cells. Intense injury may destroy resident renal cells by necrosis or apoptosis resulting in fibrinoid necrosis. When injury is less intense, endocapillary cells respond by proliferating and production of extracellular matrix (proliferative lesions). Renal biopsy, examination of urine sediment and measurement of C3 levels (and to less anti-DNA titers) are essential for the management of lupus nephritis. Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by thrombotic episodes in the arterial or venous circulation, in the presence of antiphospholipid antibodies (aPL), namely lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2glycoprotein-I antibodies (anti-β2GPI). Catastrophic APS (CAPS) is a very rare (---lt---1%) and extremely severe variant of APS. It is characterized by multiple systems and thrombotic organ involvement that occurs in a very short period (days to weeks). Renal involvement is a common feature in CAPS, the most frequent finding is thrombotic microangiopathy (TMA), but other chronic lesions of APSN can also be found.

Listeria monocytogenes contaminates various types of food. It turns out that ready-to-eat foods can be a very common source of this pathogenic bacteria. The aim of this study was to evaluate the microbial quality of ready-to-eat foods. The main focus was given on evaluation of the presence of L. monocytogenes in this group of food. Total number of 50 samples were devided into three categories: pastries (n = 29), salads (n = 13) and others (n = 8). All samples were analyzed for presence of L. monocytogenes using a conventional cultivation method ISO 11290-1:2017. As confirmation tests were used API Listeria test and PCR. The presence of L. monocytogenes was detected in 3 (1.5%) samples. All positively tested samples belonged to the category pastries, specifically: Caesar wrap, Caprese mozzarella and dried tomatoes tortilla, Halloumi cheese and roasted pepper tortilla. The results of this study indicate that consumption of RTE foods can pose a risk of listeriosis, especially for consumers from susceptible risk groups.
Hydraulic Structures as Flow Measuring Devices

Discharge measurement is the base of proper water management. The effective design and operation of hydraulic structures under both normal and extreme flow conditions depend on the quality of hydrological data. Understanding the water system requires consistent and long-term measurement. Despite that, the gauging station network is sparse, and its numbers are declining worldwide. This article aims to draw attention to the possibility of accurate flow measurement using existing hydraulic structures. Flow over a hydraulic structure profile is a physically well-defined phenomenon as the construction shape is fixed and simple compared to river profiles. The discharge can be derived from rating curves, turbine characteristics, and several easily measured variables. That allows continuous discharge measurement. The accuracy is compared with the gauging station on the river. Suitable technical solutions for ensuring and monitoring ecological flow are discussed.

Background: The new resurgence of human Monkeypox (Mpox) cases, both within and outside of the central and western African countries, is causing concern among public health officials worldwide. Pediatric physicians play an important role in Mpox surveillance and case management; thus, this study aims to determine the level of Mpox knowledge among pediatric residents in Saudi Arabia.
Methods: A cross-sectional study was done from November 21 to December 28, 2022, in Riyadh, the capital of Saudi Arabia involving 128 pediatric residents' physicians chosen through systematic random sampling. A validated, semi-structured, self-administered questionnaire was used to collect data. R-software was used to analyze the data. The chi-square test was used to investigate the relationship between the knowledge score and the sociodemographic independent variables.
Results: Among the 128 pediatric residents' physicians who participated in this study, the majority (65.7%) were aged >26 years. More of the respondents were female (57%), married (63.2%), and in their junior level of residency years (48.4%). The majority (66%) of the respondents have good knowledge of Mpox. Being a senior resident, getting a full dose of COVID-19 vaccines, and having recently heard about Mpox outbreaks were statistically significant factors associated with good scores in knowledge about Mpox. The main sources of information were medical education, radio, television, and newspaper.
Conclusions: Despite the adequate level of knowledge about the Mpox gap among pediatric residents' physicians, it is recommended that targeted intervention could be a channel through organized continuous medical education and social media to improve the knowledge about any new emergent diseases.

التنافس التجاري الهولندي – الانكليزي في منطقة الخليج العربي 1623-1654م.
Authors: Hussain Al-Dulaimi Yousef Sami Farhan
Published: January 2023

شهدت منطقة الخليج العربي تنافساً تجارياً كبيراً بين الهولنديين والانكليز للحصول موطئ قدم في منطقة الخليج للسيطرة على طرق الملاحة والتجارة معاً، إذ شهد العام 1623 بداية حصول الهولنديين على مركز تجارة لهم في منطقة الخليج، وبالتالي فتح باب التنافس الاقتصادي بين الدولتين .
بلغ التنافس الهولندي - الانكليزي مرحلة كبيرة، إذ كان الهولنديون متفوقين على الانكليز، واستخدموا عدة وسائل غير مشروعة للحصول على الامتيازات منها: الهدايا والرشاوي والتهديد والوعيد، وبالتالي عانى الانكليز كثيراً في منطقة الخليج العربي، فتدهورت وكالاتهم وكسدت تجارتهم من جراء السيطرة الهولندية على التجارة في المنطقة، إذ زاحم الهولنديون الانكليز في كل المناطق التجارية في منطقة الخليج العربي، ولم ينته التنافس بينهم حتى اندلاع حرب عام 1652، وابرام الصلح بينهما عام 1654، لذلك يمكن القول إن السيطرة الهولندية على منطقة الخليج كانت سيطرة تامة واضحة المعالم، وأثرت على تجارة الانكليز بشكل كبير .
