Introduction: Since Autorefractors nowadays have become mainstream and available in almost all clinical setups Autorefractors to make measurements swiftly. So in such a situation , it is necessary to compare the results of different refraction measurement devices including Autorefractors and retinoscopy with subjective corrections in Myopia and Hypermetropia. Methods : This is a descriptive study done among 100 patients visiting Ophthalmology OPD with Myopia and Hypermetropia in Saveetha medical college selected by convenience Sampling . The data collect ed will be tabulated and analyzed using SPSS. Results: Patients were divided into two age groups to find out age wise distribution of type of refractive errors and comparing the results from the subjective examination and results given by the Autorefractive meter it is clearly from this study that the difference between two methods was almost negligible and that Autorefractors are also a reliable method of measurement in a large clinical setup. But, on the other hand, manual retinoscopy still prove to be far better and efficacious technique yielding accurate results when it is used to check for refractive errors in individuals. Conclusion: In this study, we conclude that autorefractors are also reliable and can also be used to estimate refractive errors in a clinical setup, even though manual retinoscopy remains the most accurate and efficacious method..
Transvaginal Ultrasound Evaluation Of Cesarean Section Niche Scar During Pregnancy: A Prospective Longitudinal Study
Authors: Abdel-Rahman Ahmed Morsy Saad , Hassanin Tamer Mahmoud zaki 
Published: October 2023

Background and Objectives: To determine the prevalence of a CS scar niche during pregnancy using transvaginal ultrasound imaging, and to determine the relationship between the evolution of the CS scar niche and the ultimate pregnancy result. Materials and Methods: Transvaginal sonography was used in this prospective observational research to look at the uterine scars of 100 women at 11+0-13+6, 18+0-20+6 and 32+0-35+6 weeks of pregnancy. When the region of hypoechogenic myometrial discontinuity of the lower uterine section was discovered, a scar was discernible while pregnant. An indentation at the location of the CS scar with a depth of at least 2 mm in the sagittal axis was designated as the CS scar niche (or "defect"). Myometrial thickness next to the niche and the remaining myometrial thickness were used to quantify the hypoechogenic portion of the CS niche in two dimensions. (RMT). The entire lower uterine segment (LUS) thickness and the myometrial layer thickness were measured during the second and third trimesters of pregnancy at the thinnest portion of the scar area. In a non-selected subset of patients (n=20), CS scars were measured by two separate examiners. Scar visibility was evaluated using descriptive analysis, and the intraclass correlation coefficient (ICC) was computed to demonstrate the degree of absolute agreement between two observers for measuring scars. Maternal age, BMI, smoking status, prior vaginal deliveries, obstetric complications, and a history of uterine curettage were among the factors looked into as potential contributors to the CS scar niche. The hospital's computerized medical database provided clinical statistics on pregnancy outcomes and complications. Results: 80.9% of the ladies could see the scar. A CS scar niche was prevalent in 53.6% of people with a noticeable CS scar. Excellent intra- and interobserver agreement was observed for CS scar niche readings. There was no statistically significant correlation between maternal age, BMI, gestational diabetes, smoking status, previous vaginal delivery after CS, and niche development when subgroups of women were compared in terms of CS scar niche and non-niche. In contrast to 34.4 % of the women who did not have uterine curettage, 56.3% of the women who had done uterine curettage had uterine scar niches. Conclusions: The CS scar niche could be reproducibly measured by a transvaginal scan in half of the cases with a visible CS scar at the first trimester of pregnancy, according to an ultrasonography evaluation. An increased chance of uterine niche formation in a subsequent pregnancy was linked to prior uterine curettage. The CS scar area may be connected to uterine scar dehiscence.

Authors: Moussa Abdelraheem Mohammed Abdelraheem , Abdel-Rahman Ahmed Morsy Saad 
Published: October 2023

Background: The application of an IUD to the female after placenta delivery during a caesarean section had several benefits since the female was under anesthetic, which reduced the need for additional manipulation and pain, and the female at the time of delivery had a strong desire for family planning. IUDs placed postpartum experienced numerous disengagements, including bleeding and displacement. Objectives: To evaluate the efficacy of post placental IUD insertion during cesarean section in 100 patients. Patient and methods: A prospective study was conducted at obstetrics and gynecology department of Damanhur Medical National Institute in the period from March 2022 to March 2023. Group I: included 52 women who agreed to insert immediate post placental IUD at the cesarean delivery. Group II: included 48 women as control group. The type of IUD used was cupper-T IUD, both groups were assessed as regard to time of cesarean section (CS), amount of postoperative bleeding, postoperative pain, occurrence of infection, any displacement of IUDs, failure of contraception and patients’ satisfaction. Results: In both groups, the demographic information was comparable. The medical histories of the investigated patients and the control group did not differ significantly according to our research. The study group's caesarean procedure took a little longer to complete. There were no appreciable differences between the two groups in terms of infection, puerperal hemorrhage, or IUD displacement. Both groups' satisfaction levels were displayed as either pain or displacement. In the research and control groups, the expulsion rates were 3.92% and 0.00%, respectively. Conclusion: Based on our research, we draw the conclusion that IUD insertion during CS is safe and effective, avoiding the reasons why it can be challenging to insert an IUD after puerperium and having a low expulsion rate; so, it can be considered a standard procedure.
The influence of agricultural land on the level of airborne Alternaria spores
Authors: Havrylenko Ksenia 
Published: October 2023

Aim of the research was to investigate the impact of agricultural activity on the concentration of Alternaria spores.
Materials and methods. The study was carried out at the Department of Medical Biology, Parasitology and Genetics of the ZSMPhU. Samples were collected using a 7-day volumetric sampler of the Hirst type, using the volumetric method. Samples were identified under a light microscope, and spore identification and counting were limited to genus levels. The relationship between seasonal Alternaria spore levels and harvest rates was analysed using Pearson's correlation method. The effect of meteorological conditions and agricultural activity on the daily concentration of Alternaria was analysed using stepwise correlation based on logarithmically transformed daily average spore counts. Classical leave-one-out cross-validation (LOOCV) was used to estimate the mean square error (MSE), associated with this model and Bayesian information criterion (BIC) was used to assess its accuracy.
Results. Seasonal characteristics of Alternaria spores and agricultural activity in Zaporizhzhia and Dnipro regions were analysed. The connection of some seasonal and daily indicators with harvesting rates and meteorological conditions was determined. Two models with 5 and 9 parameters were found that best explain the dynamics of Alternaria spores.
Conclusions. The most significant parameters positively correlated with Alternaria spore levels were temperature, pressure, westerly wind and wheat yield; relative humidity was negatively correlated
Vitamin A accelerates the process of liver regeneration in the initial stages of Сu - induced fibrosis
Authors: Bozhkov Anatoly , Bilovetska Svitlana 
Published: October 2023

Aim: To test the hypothesis about the possible role of vitamin A in normalizing the functional activity of the liver with Cu-induced fibrosis by increasing the regeneration process.
Materials and methods: Experiments were conducted on 20 sexually mature male Wistar rats, which were divided into 4 groups: a control group that was not exposed to copper sulfate and vitamin A, a group that was at the initial stage of liver fibrosis, which was provided by three consecutive administrations of copper sulfate at a dose of 1 mg/100 g of weight (one series of injections), a group that was at the stage of intensive development of fibrosis (F2), which was carried out by two consecutive series of copper sulfate injections with an interval of 3 days between injections, and a group that received vitamin A three times daily in a dose of 300 IU/100 g of weight between two series of intoxication. Body weight dynamics, relative liver weight, histological changes in liver tissues and the number of binuclear hepatocytes were determined.
Results: It has been found that animals with Cu-induced liver fibrosis did not gain or lose body weight, and the introduction of vitamin A ensured the restoration of body weight growth, and they slightly lagged behind the control group. In animals with liver fibrosis that received vitamin A, the relative weight of the liver was slightly increased and there were 2 times more binuclear hepatocytes. The structural organization of the liver tissue changed to a minor extent, and to the greatest extent there was an increase in the thickness of the Glisson’s capsule, in which immunocompetent cells were incorporated.
Conclusions: Vitamin A contributed to the normalization of liver function against the background of the development of fibrosis. The mechanism of normalization can be ensured due to an increase in the number of binuclear hepatocytes, a slight increase in the relative weight of the liver, and was accompanied by an increase in the thickness of the Glisson’s capsule, in which immunocompetent cells were incorporated

Published: October 2023

The aim of the study was to compare lag screw and standard (Champy’s) miniplate fixation in the management of mandibular angle fractures and to analyze advantages and disadvantages of one over the other. A total of 30 patients involving mandibular angle fracture reporting to the Department of Oral, Maxillofacial and Reconstructive Surgery, Bapuji Dental College and Hospital, Davangere, were included in the study. Patients were divided into two groups randomly. The procedure was carried out under general anesthesia. Following strict aseptic precautions, an appropriate intraoral/extra-oral incision was selected; fracture site identified, reduced, and after obtaining satisfactory occlusion, temporary maxillo-mandibular fixation was placed using either Erich’s arch bar or Ivy loop eyelet wiring. Fixation was done using either standard miniplate (Group 1) or lag screw (Group 2). The patients were followed up for a period of 2 months at the interval of 1 week, 2 weeks, 4 weeks, and 8 weeks by a blinded experienced oral surgeon for infection, segmental mobility, postoperative occlusion and radiological evaluation of reduction and fixation. Duration of fixation was found to be less in lag screw group than in miniplate group. Radiological evaluation of reduction and fixation was significant in both the groups. No significant difference was found between both the groups in clinical parameters such as infection, segmental mobility and postoperative occlusion. The clinical outcomes of both the lag screw system and standard miniplate systems in the present study were similar. However, the following advantages with the use of lag screw can be highlighted: Relatively lesser fixation time, Superior fracture fragment stability, fewer complications, Stable occlusion & less hardware, less cost required.
THE PHENOMENON OF SOCIAL ACCOMMODATION AS A SUBJECT OF SCIENTIFIC ANALYSIS
Authors: Bazylenko Kateryna 
Published: October 2023

In the article, the author conducted a theoretical analysis of modern psychological literature on the problem of social accommodation and determined that social accommodation includes various psychological components that affect the way people interact and adapt to others in social situations. The psychological components of social accommodation may vary from individual to individual, but developing and improving these skills can contribute to improved social accommodation and interactions with other people. Social accommodation is the process by which an individual changes his or her behavior, speech, or thoughts to meet the demands or expectations of another person or social situation. Social accommodation can be conscious or unconscious, sometimes it is use to reduce conflict or ensure harmonious social interaction. Social accommodation usually aims to ensure harmonious social interaction and avoid conflicts in specific situations.
The purpose of the article is to conduct a theoretical analysis of modern research in psychological science and reveal the essence of the phenomenon of social accommodation.
Social accommodation can be an important element of social adaptability, but it is important to remember that accommodation must balance; sometimes its excessive use can lead to the loss of one's own identity or need.
The study of social accommodation in psychology and other social sciences is an important and dynamic direction, since the perspectives of further research may be the study of the influence of cultural factors on social accommodation and the study of social accommodation, which can help to better understand the ways of resolving conflicts and conducting effective negotiations, as well as the influence of social accommodations for attitudes towards oneself and others, etc.
Technology of Repairing the Active Main Pipeline Using Braze-Welded Couplings
Authors: Tymchik Grigoriy , Podolian Aleksandr , Serhiienko Kateryna 
Published: October 2023

Background. During operation, the main pipeline needs to be repaired. During periodic diagnostics of the pipeline state defects are detected, some of which are unacceptable. The classic repairing method, that involves the shutdown of the pipeline with subsequent replacement of its defective spots, requires significant financial costs and is associated with a forced pipeline outage and environmental violation.
Objective. The purpose of this article is to improve the technology of reinforcing sections of main high-pressure pipeline with welded couplings, which are filled with molten metal by allowing obtaining high efficiency of pipe strengthening of medium and small diameters.
Methods. Strength improvement of the active pipeline spots is realized by installing brazed-welded couplings on an active main pipeline. Strengthening the pipeline with the coupling consists in the redistribution of the load part from the pipe to the wall of the coupling, which leads to a decrease of the stress level in the pipe wall. The reinforcement efficiency of the pipeline could be evaluated by the degree of reduction of circumferential stresses in the fixed pipe wall.
Results. The article suggests a technique for strength improvement of pipeline spots using couplings filled with a molten metal that has a high elasticity modulus. The operations of formation of under-coupling layer with the parameters that provide achievement of the maximum value of the stresses reduction degree in the reinforced pipe are proposed, while ensuring an even load distribution between the wall of the pipeline spot being repaired and the coupling shell. An improved technology for fixing defective spots of the active pipeline has been proposed, designs for front seals have been proposed that facilitate the formation of under-coupling layer with optimal parameters. The proposed technique makes it possible to increase the efficiency of the pipe strengthening of small and medium diameters.
Conclusions. The article proposes an improved technology of the defective spots reinforcing of the active main pipeline using braze-welded coupling. The focus is on the design of mechanical seals that ensure the tightness of the under-coupling space during the formation of the coupling layer.
Further research would be performed in the direction of developing a mathematical model of the pipeline reinforced with braze-welded coupling, taking into account temperature changes during heating and cooling of the coupling structures during the formation of the under-coupling layer. Some research will be also performed to improve the coupling structures and methods of quality control of their mounting on the pipe.
