Authors: AKSOY Ercan
Published: May 2022

The Redif Barracks situated in Vezirköprü district has served as a barracks, school and public Education center since it was constructed. It is one of the rare examples of non-domestic civil architecture and it is important to sustain that. Aim: To determine the current features to protect, and to refunction the sustainability of the Redif Barracks which was used as a public Education center but evacuated recently and which faced malpractices. Method: The size was measured through modern techniques and building surveys were made. Thus, deterioration and problems with the structure were determined. Dating of the structure was made after a thorough literature review. While making suggestions on restitution, protection and functioning decisions were made. Findings: It was found that the post structure has been used up to today by various functions and has faced structural differences. It was also found that the post faced deteriorations by natural, human-driven and atmospheric causes. It was determined that the deterioration process accelerated since the structure was abandoned. It was concluded that the structure can be sustained by providing a new function suitable with its features and location. Conclusion: When the researches about the Redif Barracks were examined, it was determined that there was no mention of a barracks in Vezirköprü. To reverse the deterioration process of the structure which was documented through measurements, it is important to interfere. Therefore, it is understood that the structure should be kept alive by giving it the right function.

Development of the seed-cones Taxus canadensis in culture (Tsytsin Main Botanical Garden RAS, Moscow, Russia)
Authors:   Tsytsin Main Botanical Garden RAS, Trusov Nikolay A.
Published: May 2022

The development of the seed-cones of Taxus canadensis was studied. Aril is multilayered. The seed coat is multi-layered, its structure changes during development. Initially, it consists of 33–35 layers of cells, and by the time of maturation they are reduced to 10 layers. A marker sign of changes of seed-cones structure is the appearance of an aril from under the scales. At this time, there is an active thickening of the cuticle of the epidermic cells of the seed, sclerenchymatization of zone I of mesotesta cells and obliteration of zone II, differentiation of cells in the chalaza area. The nucellus is reduced, the endosperm and embryo grow, and oil droplets appear in the cells of the endosperm. A week later, even greater differentiation of cells in the chalaza area starts and a rapid growth of the aril is observed during the week.
Hybrid Missing Value Imputation Algorithm- KLR
Authors: Rajneesh Kumar, Anurag Jain Deepti Sharma,
Published: May 2022

The data mining process mainly deals with the estimation, prediction, pattern extraction, and classification in big databases. The presence of missing values in the dataset decreases the accuracy of data mining classifiers. Therefore it is necessary to deal with missing values in the dataset to achieve accurate results. To improve the quality of data and prediction accuracy in the classification process, the authors have proposed a new hybrid missing value prediction algorithm, KLR, by combining the KNN and linear regression approach. The proposed KLR algorithm has been used for class validation and missing values imputation. Wisconsin Breast Cancer Diagnostic Dataset of 569 instances with 32 attributes from the machine learning repository of UCI, Irvinewasused to conduct the study. The Pearson Coefficient Correlation method is used for feature selection.Data normalization is performed using Min-max scaling technique. The Scikit-learn library for machine learning in python is used to complete all the experiments as the experimental framework. The mean square error method is used to evaluate the performance of the model. The proposed KLR algorithm with 450 nearest neighbors out of 569 gives the lowest MSE ie 0.00188 and more accurately predicts the missing values as compared to the classic models.

Published: May 2022

In the present study, quantitative model and methods that analyze dynamic system of communication flow have been developed in the domain of queuing theory under uncertain environment. The study approach supports model-based queue design as opposed to creative engineering. Some critical aspects and results of queue model and fuzzy set theory has been reviewed in brief and the application of bulk queue model to communication network under imprecise data has been discussed. We have assumed that the arrival pattern, service pattern as well covariance between incoming and transmitted packets all are fuzzy in nature. The system characteristics with defuzzification process have been explored on the basis of lower and upper bound at possibility level alpha and signed distance method. The validity of the results has been analyzed through numerical illustration and graphical study.
Time and Cost Management in the Construction of Large Energy Facilities
Authors: Andrey A. Mihasek Nikolay Y. Kuzmin,
Published: May 2022

The article deals with the problems of time and cost management in the construction of large energy facilities. The practical value of standards in the field of time and cost management in the construction of large energy facilities is often questioned by specialists in various fields of project activity. Practitioners at lower and intermediate levels often complain about the lack of clear and effective tools for solving specific problems in project management practice. However, the skillful application of standards can not only increase the likelihood of success for a wide range of diverse projects of large energy facilities with obtaining expected business values "at the output" of the project. The purpose of this study was to study the features of management terms and cost in the construction of large energy facilities. The objectives of the study included establishing links between the methods recommended by the project management body of knowledge (PMBoK) guidelines for determining the project budget and the methods used in practice for determining the cost of construction projects for large energy facilities, formalized in the current regulatory documents and state building codes of Russia. For this (according to the PMBoK standard), the basic methodological foundations of the project cost management process, its components and characteristic features were determined. The main stages of the life cycle of construction projects of large energy facilities, in which the cost of design work is assessed, are determined, the goals of such an assessment and the project participants who carry it out are determined. As a result, a complete methodological identity was established between the methods for assessing the project cost of large energy facilities recommended by the PMBoK standard and the methods for determining the cost of construction specified in the current regulatory documents in the construction industry in Russia.

The need to ensure a high level of system stability especially increases (with an increase in the number of clients). Today, many tools have been created and approaches have been developed to ensure a high level of fault - tolerance [9-11]. In this work, some of the promising approaches are considered, using which a geographically distributed system was developed and launched that provides unified access to the API of trading platforms. The emphasis is not on detailed instructions for creating the system, but on the key points and tools.
Prediction of Battery Lifetime using Hybrid Solar Power System
Authors: Azita Laily Yuso, Murizah Kassim, Nani Fadzlina Naim Norsuzila Ya’acob, Abang Syahizam Gobil Abang Apandi,
Published: May 2022

In recent years there has been a great concern to implement more renewable energy sources to supply energy around the world. Solar energy seems to be a good choice since it is accessible and does not cause pollution. The main problem with the solar system is that energy production only takes place when the sun is shining. Large storage systems need to be developed to provide a constant and reliable source of electricity when the sun is not shining at night or when a cloud goes overhead. The main objective of this study is to predict the lifetime of the battery in the solar hybrid system. This will involve investigating the stress factor that contributes to the battery. From the simulation done in Matlab Simulink, a graph of state of charge (SOC) versus time is gathered with the help of the Rainflow algorithm extracted from the fatigue cycle of the battery. Once the fatigue cycle is determined, the ageing rate will be calculated. The outcome of this study is battery lifetime can be predicted and the proper battery can be used to reduce for maintenance purposes.
Design Simulation and Assessment of Prediction of Mortality in Intensive Care Unit Using Intelligent Algorithms
Authors: Ashish Raj, Vijay Kumar Satish Kumar Alaria, Vivek Sharma,
Published: May 2022

Big data in healthcare refers to vast amounts of data generated by the adoption of digital technology that collect patient records and aid in the management of hospital performance, which would otherwise be too large and complex for traditional technologies. We have chosen Mortality Prediction in Hospital ICU for this paper. In recent years, there has been a determined push in hospitals to implement digital health record systems. Between 2008 and 2014, the number of non-federal acute care hospitals in the United States using basic digital systems climbed from 9.4 percent to 75.5 percent. In the near future, the percentage increase in the hospital's digital information will be enormous, and we will need to apply modern big data techniques to analyse those datasets. In the best sense, the future of medical diagnosis and therapy is a combination of medical judgement and an algorithmic diagnostic tool based on large medical information. For our research, we used the MIMIC III database. In this paper, we will go over why Mortality Prediction in ICU is interesting, as well as the method we used to examine and address the problem.
Numerical Simulation Design of Improved Meta Heuristic Charging Scheduling for Electrical Vehicle Applications
Authors: Virendra Swaroop Sangtani, Vikash Kajla Bharat Bhushan Jain, Nandkishor Gupta,
Published: May 2022

The driving range of an electric car is restricted. There aren't many charging stations in India, so those that exist must be efficient. This study's purpose is to develop a set of criteria for selecting successful algorithms for scheduling EV charging in photovoltaic micro grids Due to the similarities between EV charging scheduling and timetabling scheduling, research works on other fields' scheduling were thoroughly analyzed. This involves scheduling issues. The paper also reviews scheduling constraints, particularly for solar-powered electric vehicles. Charging electric vehicles on smart micro grids using PV is encouraged. Electric automobiles (EVs) are gaining worldwide favour over conventional cars. However, the higher purchase price of an EV may still be the main market obstacle. Customers choose EVs for various reasons, including lower carbon emissions and higher performance. Consumers with environmental awareness and a renewable energy perspective are needed. A recent study found that a 1% increase in renewable energy sources increases EV demand by 2-6%. It is acknowledged that EVs provide new potential for control and consumption flexibility by adjusting the charging power at a given moment. Particle swarm optimization for grid charging electric vehicles Electric vehicles must be recharged after a distance. Because electric vehicles are a viable alternative to internal combustion engines, the technology has grown rapidly. Electric vehicles have fewer emissions, better energy efficiency, less noise pollution, and cheaper operating and maintenance expenses. We plan to use this research to identify efficient algorithms for charging electric vehicles (EVs) in photovoltaic microgrids. The similarities between scheduling timetabling and EV charging prompted a review of literature on scheduling in many domains, particularly timetabling.
Views on Scientific Research Methods: A Study of North Indian Engineering Faculty Members
Authors: A. K. Malik Manusmriti Sharma,
Published: May 2022

Scientific research is a significant component in the field of education. It is a systematic effort not only to get proficiency in teaching but also to stimulate independent search for new knowledge, to unravel scientific issues and to identify how to study the information. This study aimed to investigate the views of North Indian engineering faculty members on the scientific research methods (SRM). The research data was collected through a structured questionnaire and interviews. The faculty members were asked questions about scientific research methods and their opinion about how to improve the effectiveness of   engineering faculty in teaching and research. To this aim, the main effects of the scientific research methods on academics and research have been studied. The research work data was collected from more than five hundred faculty members and was analysed with the descriptive method. The findings indicate a positive relationship between teaching pedagogy and scientific research methods. The results also revealed that the engineering faculty members lacked knowledge about scientific research methods which further impedes the systematic teaching-learning process.
Combined application of an optical sensor and a common non-destructive instrument for corrosion monitoring in reinforced concrete members
Authors: Thapa S , Sharma R P
Published: May 2022

The reliable monitoring of the progression or extent of pitting-type corrosion in reinforced concrete members requires great effort due to non-uniformity. This paper presents a new approach for measuring the progression and extent of pitting-type (non-uniform) corrosion in reinforced concrete members by combining both non-destructive testing with optical fibre sensing results. Accelerated corrosion on the reinforcement (rebar) of the specimen was produced artificially using an alternate wetting and drying process in sodium chloride solution with 7.5% and 10% concentrations. The multimode optical fibre patch cords were attached to the reinforcement in three different arrangements in a single specimen (normal optical patch cord and loose and firm microbend patch cords). Intensity loss in a propagating light travelling inside an optical fibre takes place due to the development of pressure from surrounding concrete on the fibre from rust formation (corrosion). The study also describes the effect of corrosion in half-cell potentiometer, chloride ion resistivity and indirect pulse velocity readings obtained from the specimen. A later study found that the use of an optical microbend sensor is an effective alternate method for determining the starting time of initial depassivation in the reinforcement and validates it using half-cell potentiometer values. The study also developed models to predict overall mass loss in the rebar due to corrosion using combined non-destructive testing methods.
A relative torsional vibration monitoring method for intelligent ships and associated error analysis

Published: May 2022

In this era of rapidly developing transport technology, shipping accounts for two thirds of the total international trade and transport industry. Nowadays, 'ship intelligence' is an important avenue to pursue in the development of the shipping industry and it requires ships and their
working machinery to undergo real-time and high-precision inspection and diagnoses of their operational state. This paper develops a simple method for monitoring relative torsional vibration using multiple measuring points, which is suitable for the monitoring of intelligent ship rotating
machinery. A proof-ofprinciple prototype is also designed to verify whether this calculational method can achieve clearer and more accurate physical significance and engineering practicability compared with the traditional single-point measuring method. According to the test results, under
the condition of 100 pulses per revolution and at a speed of less than 3000 r/min, the relative error of speed measurement of the proof-of-principle prototype is within ±0.011%, which is close to the theoretical maximum accuracy of a 54 MHz sampling rate. The measurement result for
the relative torsional angle shows that the maximum error is less than 0.17 mrad, the relative error is less than 1.75% and the maximum error in the amplitudes of the first and third harmonics is 9 mdeg. These accuracies are higher than those of the traditional method, which are 2.62% and
12 mdeg, respectively, in this study. Under the condition of speed fluctuations and rolling vibration, distortion occurs in the time-domain and frequency-domain torsional angle curves when the single-point measuring method is adopted. With the multi-point measuring method, much more accurate
measurement values of the torsional angle are acquired compared with the single-point measuring method and accurate time-domain and frequency-domain curves are also obtained. Finally, the health status of the torsional angle is evaluated using an intelligent dynamic alarm system with a torsional
vibration threshold, which has a better evaluation effect in line with the engineering practice and specification requirements. Therefore, this simple multi-point relative torsional vibration inspection method has universal applicability and wide application value.
Racism and Discursive Belongings
Authors: Geier Thomas
Published: May 2022

This paper is based on the assumption that migration movements irritate the orders of belonging associated with and produced by symbolic, structural, legal, and territorial borders. In the discourses accompanying such crises, these crises themselves become thematic in a certain way and can thus be understood and contextualized. In their thematization, solutions to the respective crises are also presented as desirable. In this sense, they can also be understood in terms of their contribution to a (European) subjectivation. Discourses have the quality of education insofar as they convey world and self-relations by means of which individuals can (learn to) understand themselves as subjects. In the field of migration, discourses are connected with symbolic orders of belonging, which are often closely related to racisms.
The Planetary Justice Crisis, Structural Racism and Sustainability Education
Authors: Carstensen-Egwuom Inken , Schröder Birte
Published: May 2022

We follow two main arguments in our contribution: First, we contend that there is a vital need to connect theories around racism to discussions about the Planetary Ecological Crisis. This is a link that has hardly been addressed in German-speaking social science research on racism. And secondly, we argue for a critical engagement with the workings of racism within Education for Sustainable Development (ESD), an educational field with a strongly normative underpinning that (cl)aims to work for a “better future for all”. Questions on how the futurity inherent in this claim and the divisions within the “all” have colonial and racist underpinnings are imperative for an engagement with ESD.

Published: May 2022

The size of the tray in seedling production has a direct influence on the area of ​​root development and availability of resources, such as water as well as nutrients, with a potential impact on the seedling final quality. The objective of this work was to analyse the impact of the tray size on the development of cucumber seedlings. As such, this study was developed in two experiments: in the first, seedlings produced in trays with 50 and 128 cells were compared, while in the second, trays with 50, 98, and 128 cells were considered. For that, polyethylene trays and commercial substrate were used. The trays were kept in a greenhouse, and evaluations were carried out at 21 days after sowing. Morphological development and SPAD index were analysed. The data were submitted to ANOVA and the means compared by the Tukey test (0.05). Linear correlation was performed between the analysed variables. The best development of cucumber seedlings was obtained by adopting trays with 50 cells. Cucumber seedlings produced in trays with a higher number of cells show reduced development, mass accumulation and lower photosynthetic activity.
The Narrative Composition Strategy of The Movie  Possibilities and Limitations of Creation Using Pansori Narratives
Authors: Kwon Do young
Published: May 2022

The movie  ambitiously reproduces the process of forming pansori works by combining ‘Simcheongga’ and ‘Chunhyangga’. In this paper, focusing on the literary aspect of pansori, and analyzing the strategy of combining the narratives, the possibilities and limitations of using the pansori narrative as a story content were examined. In the movie , when each of the characters is the agent of narrative, ① the narrative of a conspiracy bunch and a ‘selling oneself organization’, ② the narrative of the 'Gan-nan' kidnapped by the ‘selling oneself organization’, ③ the narrative of 'Hak-gyu' and his party who search for 'Gan-nan', ④ the narrative of the fallen yangban. Each narrative proceeds in its own direction and merges into one at the end of the grand banquet scene at the end, maximizing the dramatic effect. By reproducing the process of creating 'Simcheongga' through this narrative composition, it showed a narrative of optimism based on situational setting and character creation based on the reality of the time, and empirical universality of the people. By combining the narrative of 'Chunhyangga' and having a narrative composition in which core problems are resolved through the strategy of forming the climax, Hak-gyu's narrative, which set out to solve the problems that occurred to his family, is the story of the people suffering from similar life pains. It has moved on to a narrative of solidarity that seeks hope together. However, it is a pity that it has become an easy choice for solving the problem, and that it has not been recontextualized as a work that can give sympathy and emotion to modern audiences through new interpretations and deep insights. I support the movie , which showed a meaningful attempt. However, it is necessary to pay more attention to the essence of pansori to be preserved and developed, and it is necessary to continue to think more actively about how to revive the narrative characteristics of pansori as a 'culture to be created' in the future.
Creative Becomings
Authors: Gamboa Martín
Published: May 2022

This article describes the presence of cultural traits of Basque tradition in the visual arts and Uruguayan literature of the 20th and early 21st centuries. Likewise, the research deconstructs the concept of “cultural legacy” applied in studies regarding multiculturalism in Uruguay. This approach implied a type of degradation at a cultural level, in which successive generations (first, second, third, and fourth) gradually lost their “original culture”. However, the cultural traits of the Basque ethnic group that appear in the visual arts and literature were shaped by the descendants of the first and second generations. The research demonstrates that certain cultural manifestations can re-emerge among the pieces created by the descendants of the second, third or fourth generation, rather than by the generation that arrived in the country for the first time. On the whole, the article analyses the continuum of the cultural legacy of Basque immigration in Uruguay from an anthropological point of view. As a result, the work presents a non-linear approach to the cultural contribution of Basque immigrants in this country.

Published: May 2022

En los últimos 30 años (cosechas agrícolas de 1991/92 a 2021/2022), el maíz ha vivido una verdadera revolución en Brasil. Actualmente, el país se ha consolidado como el tercer productor y segundo exportador de este cereal, con una producción de más de 100 millones de toneladas de este grano por año agrícola. En este período, el cultivo de soja se destaca como el gran impulsor de los avances tecnológicos, llevando al maíz y a otros cultivos a posiciones más destacadas y transformando los sistemas de producción de granos; que antes eran de monocultivo o rotación, a sistemas más intensificados, con dos (o más) cultivos agrícolas por año en la misma área. La región del Cerrado brasileño, antes considerada no apta para la agricultura, es hoy el gran granero de la producción de granos de Brasil. En estas tres décadas de escalada en la producción de maíz, se destacan algunos hitos legales y tecnológicos, como la Ley de Protección de Cultivares y su reglamento (desde 1997), el Sistema de Siembra Directa, el cultivo de maíz en segunda cosecha o “safrinha” (después de la soja) y el uso de biotecnologías. Estos factores fueron determinantes para que el crecimiento de la producción de maíz superara en más de 3,6 veces el volumen de la campaña agrícola 1991/92, mientras que el área destinada al cultivo de maíz aumentó sólo 1,5 veces. Los incrementos en la productividad están ligados a tecnologías y conocimientos aplicados a la gestión de los sistemas productivos, en el binomio soja-maíz, y no solo en un cultivo aislado; permitiendo mayores avances en la producción bruta de ambos granos (rendimientos recientes en la cosecha de maíz son unas 2,5 veces mayores que hace 30 años). Este trabajo presenta datos y hechos que permitieron a Brasil salir de una posición de vulnerabilidad, en cuanto a la oferta de grano de maíz, para convertirse en un actor importante en la producción y comercialización de este cereal a nivel mundial.

Published: May 2022

It is shown that it is necessary to switch from the nominal measurement scale used for assessing the quality of fresh water to a relative one, classifying objects in proportion to the degree of severity of the measured property. A modified Harrington desirability function is proposed, asymptotically tending to zero as the controlled indicator deviates from the nominal value, but still remaining different from zero and beyond the limits of the permissible interval within the limits of insignificant violations. The use of methodology for quantitative assessment of water quality by the content of non-ferrous metals in the river is considered. Iseti (g. Yekaterinburg).

Published: May 2022

Objectives. Remineralizing therapy is widely used in the treatment of acute initial caries. However, when the protein matrix of the enamel is destroyed in the area of the initial caries, remineralizing therapy turns out to be ineffective, which requires the choice of a different method of treatment. One of these methods is the Icon (Infiltration Concept) enamel infiltration method, which allows to preserve the natural healthy tooth tissues as much as possible and restore the enamel affected by caries.

Purpose — to analyze the comparative study of the clinical efficacy of the Icon infiltration method and the deep fluoridation method in the treatment of acute initial caries.

Methodology. The article presents the results of studying the clinical efficacy of the Icon infiltration method and the deep fluoridation method in the treatment of acute initial caries of 89 teeth in 50 students of the Medical Academy. S.I. Georgievsky at the age of 18–24. Paraclinical indices were studied: hygiene index (OHI-S), the intensity of dental caries damage (CPU of teeth, CPU of cavities), means of individual hygiene for the oral cavity were selected, general remineralizing treatment was prescribed. To assess the dynamics of treatment, patients were divided into three groups of groups, taking into account the therapy.

Results. Clinical application of the Icon infiltration method in the treatment of initial caries made it possible to achieve stabilization of the pathological process and restoration of enamel in 100% of cases — there was a complete disappearance of the focus of demineralization in all teeth, elimination of clinical manifestations of acute initial caries, reduction of the degree of demineralization revealed by vital staining by 83.6%.

Conclusions. Our positive results allow us to recommend a wider clinical application of the Icon infiltration method in order to restore enamel in the treatment of initial caries.

More than 60% of patients with initial treatment in medical institutions are assigned III–IV stage, which requires combined or complex treatment. Under the influence of chemo-radiation therapy, the salivary glands are affected and the physico-chemical properties of saliva change: viscosity, pH, salivation rate, etc.

The study involved 89 people from the V.M. Efetov Crimean Republican Oncological Clinical Dispensary with a diagnosis of cancer of the oral mucosa, who, depending on the type of treatment (developed or traditional), were divided into two groups: the main one – using Laetrile in the form of rinses or oral baths for 8–14 days and the control – antitumor treatment according to the protocol (0.06% chlorhexidine solution, ointments for the elements of the lesion – levomycol, vaseline, pharmacy lotion and decoctions of chamomile and sage herbs).

A clinical and laboratory evaluation of the salivation function was performed: the volume, salivation rate and relative viscosity of the oral fluid were studied. Oral fluid after irritation of the tongue with a food irritant (0.5% citric acid) was collected in a graduated tube for 5–10 minutes and the volume was determined. The salivation rate and saliva viscosity were determined using an Oswald’s viscometer using the technique of T.L. Redinova (1986).

The features of salivation dysfunction in oncopatients receiving chemo-radiation therapy of the oral cavity are a decrease in volume (0.14 ± 0.01 ml) and velocity (0.42 ± 0.018 ml/min), as well as an increase in viscosity (7.42 ± 0.25 p.u.) saliva. The use of Laetrile for 10–14 days from the beginning of the course of chemo-radiation therapy can significantly prevent a decrease in the volume and increase in the viscosity of saliva and minimize the associated decrease in quality of life.

Authors: Yoon Sanghoo , Kim Young A
Published: May 2022

Background: Nurses comprise the majority of the healthcare workforce, and their job satisfaction can have a substantial impact on patient health.
Methods: This study aimed to provide a comprehensive overview of studies that performed statistical analyses focused on the job satisfaction of nurses and relevant factors, as well as synthesizing existing data. Overall, 144 studies published between 1986 and 2018 were reviewed for qualitative synthesis.
Results: The most frequently measured variable was job stress, followed by burnout and turnover intention. Overall, 53 studies published between 1994 and 2018 were reviewed for quantitative synthesis. In the meta-analysis, the weighted mean effect size using a random-effects model was moderate for all variables: -0.539, -0.484, and -0.395 for burnout, turnover intention, and job stress, respectively.
Conclusion: The results revealed a long history of variables related to job satisfaction among Korean nurses since data retrieval was not subject to any restrictions. These findings can be used as evidence for the formulation of policies to enhance the retention of nurses committed to their profession. Further, they can facilitate stable workforce management in healthcare.

Published: May 2022

Background: Patients with temporomandibular disorder (TMD) often have orofacial pain and may use medication without professional prescription. Self-medication and inappropriate drug intake may cause serious health problems. This cross-sectional study evaluated the self-medication profile of TMD patients, the most used medications and their effect, and the relation between self-medication and socioeconomic factors.
Methods: A non-representative sample (n=358) consisted of consecutive adult patients seeking TMD treatment in specialized referral centers for orofacial pain of two universities in São Paulo city, Brazil. A standardized questionnaire was used to collect the study variables before the TMD treatment: self-medication history, TMD pain intensity, sex, age, ethnicity, marital status, schooling and socioeconomic levels. Data were analyzed by descriptive statistics, chi-square test, and logistic regression models at the 0.05 significance level.
Results: Almost 60% of 358 TMD patients reported self-medication. Patients with severe TMD were 4.7 times more likely to self-medicate when compared to patients with low TMD intensity (O=5.7; 95% CI=2.4; 13.3; P=0.043), as well as female patients were 30% more likely to self-medicate compared to male patients (OR=2.3; 95% CI=1.1; 5.1; P<0.001). The other independent variables were not associated with self-medication. The frequencies of moderate and severe TMD in women were larger than in those in men (P<0.001). Analgesics and anti-inflammatory drugs were the most used medications. Regarding medication efficacy, 82% of patients reported some improvement after use, but 9% reported side-effect sickness.
Conclusion: Self-medication is common among TMD patients attending specialized clinics, and this inappropriate practice is more likely to occur in women and in patients with severe signs and symptoms of TMD.

Published: May 2022

Background: We assessed risk factors, antenatal and intrapartum complications associated with early-onset Gestational diabetes mellitus (GDM) in comparison with late-onset GDM.
Methods: This retrospective study included 161 GDM women having singleton pregnancies, without previous medical disorder and delivered at a tertiary care Hospital in Ha’il City, KSA from Dec 2020 till Jun 2021. Women diagnosed at < 24 weeks of pregnancy were grouped as early-onset GDM (n=71) and those diagnosed at ≥ 24 weeks as late-onset GDM (n=90). Both groups were matched for background variables. Chi-square and binary logistic regression analysis were applied with P-value significance at 0.05.
Results: Past history of GDM, macrosomia and stillbirth were significant predictors for early-onset GDM (P value 0.000, 0.002 and 0.040 respectively). Regression analysis showed early-onset GDM significantly increases the risk for recurrent urinary tract infections (AOR 2.35), polyhydramnios (AOR 2.81), reduced fetal movements (AOR 2.13), intrauterine fetal demise (AOR 8.06), macrosomia (AOR 2.16), fetal birth trauma (2.58), low APGAR score at birth (AOR 8.06), and neonatal ICU admissions (AOR 2.65). Rate of preterm birth, hypertensive disorders, labor onset (natural vs. induced) and cesarean section and intrapartum maternal complications were same in both groups.
Conclusion: Early-onset GDM significantly increases certain maternal (recurrent urinary tract infections, polyhydramnios and reduced fetal movements) and fetal complications (intrauterine fetal demise, macrosomia fetal birth trauma, low APGAR score at birth and neonatal ICU admissions). Most of these adverse pregnancy outcomes can be prevented through early registration and screening, close follow up, growth ultrasounds, and provision of efficient emergency and neonatal care services.

Background: To analyze the effect of continuous nursing model based on WeChat public health education on self-management level and treatment compliance of stroke patients.
Methods:  Overall, 98 stroke patients admitted to the Second Affiliated Hospital of Chongqing Medical University, ChongQing,400000,China from Feb 2018 to Feb 2019 were enrolled as the research objects. They were randomly and equally divided into experimental group and control group. The control group received routine nursing management model while the experimental group received continuous nursing model based on WeChat public health education to compare the self-management level, treatment compliance, life quality and other indexes between the two groups.
Results: The overall self-management level in the experimental group was significantly higher than that in the control group (P<0.05). The life quality scores in both groups after nursing intervention increased, and the scores in the experimental group after nursing intervention were significantly higher than those in the control group (P<0.001). The total treatment compliance rate in the experimental group was higher than that in the control group (P=0.001). After nursing intervention, the readmission rate and complication rate in the experimental group were significantly lower than those in the control group (P<0.05).
Conclusion: The implementation of continuous nursing model based on WeChat public health education for stroke patients can significantly enhance the self-management level, improve the cognitive level on stroke related-health knowledge, improve treatment compliance of patients in the nursing process, promote their physical and mental health, improve the life quality and effectively reduce the complication rate and readmission rate.

Background: Silver nanoparticles (AgNPs) were phyto-synthesized using Typha azerbaijanensis aerial part and root extracts, and their biological activities were investigated.
Methods: This study was conducted in the Science and Research Branch, Islamic Azad University, Tehran, Iran in 2019. In this experimental study, silver nanoparticles (AgNPs) were phyto-synthesized and the physicochemical properties of AgNPs were determined using UV-Vis (UV-Vis) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. Antibacterial and anticancer activity of synthesized AgNPs was determined using microdilution assay, and MTT 3- (4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) methods, respectively. The apoptotic effects of AgNPs were investigated using Real-Time PCR and flow cytometry techniques.
Results: Morphological analysis of the synthesized AgNPs confirmed the spherical shape of AgNPs with an average size of 10.67 to 16.69 nm. The FTIR spectrum confirmed the presence of phytochemicals from T. azerbayenensis extract at the AgNP surface. Antibacterial experiments showed that phyto-fabricated AgNPs had significant antibacterial activity against Gram-negative bacteria. The AgNPs were significantly cytotoxic against breast cancer cell line (MCF-7) through induction of apoptosis. 
Conclusion: The phyto-synthesized AgNPs had biological activities could be useful in pharmaceutical applications.
