Textile waste materials are increasing day by day with the depletion of water. This increasing concentration of ions, functional groups, and ammonia present in the water as a byproduct from the industries produce toxicity. This affects the human and aquatic life. The sustainability of the materials to rule out this toxicity can be done by Reduced Graphene Oxide synthesized by modified Hummer’s method. The composite of V-doped TiO2 and RGOwas synthesized by hydrothermal method and V-doped TiO2/RGOand perfluorocarbon synthesized by sonication. Methylene blue was used as an indicator to improve the pH of the wastewater under sunlight. The product was characterized by the powder X-ray Diffraction method. It has confirmed the synthesis of the product. The ultraviolet/visible spectroscopy was employed to study the absorbance decreases with time which is the confirmation of degradation of methylene blue with time and it was clearly observed that photocatalytic activity of the product for the degradation of methylene blue which is an organic dye and hazardous to the environment. The findings obtained can be utilize for the industrial waste-water treatment with metallic ions.

Published: May 2023

In this study, the total number of aerobic hetetotrophic bacteria (AHB) in early-stage of biofilm formed on different plastic types commonly used in daily life, namely polyethylene (PE), polypropylene (PP), polystyrene (PS) was investigated in a water recirculating test system. The Golden Horn Estuary’s water was used as a system water. The test system was operated continuously for 504 h and natural biofilm formation was ensured. The physicochemical properties of system water were measured each sampling time. Bacterial attachment was observed on all plastic surfaces even within the first hours. Also, macroscopic images proved that the biofilm layer formed and flourished on all plastic surfaces over time. After 504 h, the levels of AHB on the plastic coupons were detected as 1.4×105, 1.2×105 and 1.8×105 cells cm−2 for PE, PP and PS, respectively. To investigate the number of bacterial cells in early-stage of biofilm formation on plastic surfaces will create an important basis for future research in terms of evaluating the effects of microplastics on the environment and human health.

Published: May 2023

ABSTRACT Stress is a problem that often arises in this modern era. Stress can be acute or chronic and is determined by individual perceptions and the body's response to the pressure. Long-term exposure to continuous stress can lead to physical illness in the body (psychosomatic), one of them is skin. Unhealthy skin will also cause a decrease in self-confidence, causing stress. Therefore there is a need for psychotherapeutic intervention to overcome these disorders and to restore the body's condition. Strategies that can be done to deal with stress can include an active approach to the source of stress, seeking social support (emotional support or information from other people or seeing a psychologist) from the surrounding environment, building self-control (self-control) towards the source of the problem, as well as trying to find a positive side from stress. So that this service activity is expected to be able to educate the public, especially teenagers to be able to manage stress properly. The activity was carried out using the webinar method with 37 youth participants. The activity was carried out in 3 stages, namely pretest, limitation of material - discussion and post test. In the pretest and posttest stages the participants were given the same 5 questions. Based on the results of the pretest and posttest, it was found that there was an increase in the correct answers from 79.459% to 85.405%. This indicates that there is an increase in knowledge from the participants related to managing stress on skin health after the intervention. Based on this, it can be interpreted that community service activities with the theme "Stress Management Education as an Effort to Maintain Skin Health" can be carried out properly and increasing knowledge of participant.

EFFECT OF CHANGE IN THE COEFFICIENT OF PERMEABILITY ON CONSOLIDATION CHARACTERISTICS OF CLAYS
Authors: Fattah Mohammed Y. , Al-Shammary Ahmed S. al-Shammary( , Al-Hadidi Maysam Th.
Published: May 2023

The settlement rate and pore water pressure dissipation rate are mainly controlled by the permeability of soil. Both laboratory and field tests show that the permeability is varied during the loading and consolidation process. It is known that consolidation process is accompanied by decrease in void ratio which leads to decrease in the coefficient of permeability. The importance of the decrease of the coefficient of permeability on the time rate of settlement and pore water pressure needs to be investigated.This paper takes into account the change in coefficient of permeability during consolidation and studies its effect on consolidation characteristics of a clay layer. The finite element method is used in the analysis and the package Geo-Slope is adopted through coupling the programs SIGMA/W and SEEP/W. The relationship between the applied pressure and permeability was determined experimentally for three samples.It was concluded that the effect of permeability is clear at later times of consolidation due to decrease in void ratio and hence slower dissipation of pore water pressure. Taking into account variable permeability leads to longer times of consolidation. At later times (after 400 days), the excess pore water pressure predicted for the case of variable permeability is greater thanconventional case by about (10 – 12) %.

Authors: Kurgak V. G. , Karbivska U. M.
Published: May 2023

Purpose. To establish changes in the chemical composition, nutritional value and energy intensity of various types of perennial grasses feed under the influence of mineral fertilizers. Methods. General scientific – hypotheses, inductions and deductions, analogies, generalizations, and special – field, laboratory, analytical, mathematical-statistical, calculation-comparative. Results. The results of research on the content of organic and mineral substances in various types of perennial grasses feed, its nutritional value and energy intensity on sod-podzolic soils of the Carpathian region are presented. Conclusions. Nitrogen has the most positive effect on the chemical composition of cereal grass stands. With the fractional application of nitrogen fertilizers in a dose of N90 under each mowing against the background of application of P60K60, the content of crude protein in the dry mass of various types of grasses increased from 10.3-11.5% to 14.5-15.6%, or by 3.1- 4.0%, protein – from 7.6-8.0% to 10.0-10.8%, or by 2.2-2.4%, as well as tendentious crude fat, and the content of nitrogenfree extractive substances decreased from 46.8-51.2 to 41.9-45.9%, or by 4.2-4.9%. At the same time, the supply of digestible protein of the feed unit increased from 107-110 g to 142-152 g, or by 35-42 g. With the application of P60K60, compared to the variant without fertilizers application, the phosphorus content in the dry mass of grasses increased by 0.02-0.04% and that of potassium – by 0.20-0.36%. Most of these mineral elements, as well as raw ash, were accumulated by the Dactylis glomerata. Due to the improvement in quality through introduction of N90, perennial grasses are suitable for the production of high-quality grass feed, in particular hay, haylage and green fodder of the 1st class and artificially dried grass feed of the 3rd class.

In conclusion, every faculty has students who experience anxiety disorders, depression, and self-harm behavior. As for this research, it can be used as additional data from previous research, especially at the University where this study was taken. The limitations of this research are in the aspects of the sampling method and the limitations of measuring instruments.
Mayday! Mayday! What critical communication skills are needed for young aviators?
Authors: Mahmood Aina Suriani , Saad Noor Saazai Mat , Nur Nurhayati Mohd
Published: May 2023

Communication is one of the fundamental factors in operating complex and highly regulated industries such as aviation maintenance. Aviation graduates' job performance and career development are highly dependent on their communication skills. However, the transition from student to aviation worker requires individuals to adapt to new communication practices in the workplace. Therefore, this study was conducted to identify the oral and written communication activities that the young aviation personnel in the aviation industry frequently encounters. In addition, this study was also conducted to find out what challenges they face in terms of communication. Nine participants, young aircraft maintenance technicians and License Aircraft Engineers (LAE), were involved in semi-structured interviews. Data were analyzed thematically and managed using ATLAS.ti software. The results show that the English language is critical for the development of professional communication skills among young aircraft maintenance technicians, as they need English language skills for oral and written activities. The identified needs and challenges in communication skills would help aviation institutions develop solutions to meet the aviation industry's needs.

Faulty Memories, Favored Outcomes: How Errors Impact Learning Processes
Authors: Leonard Bridget , Hake Holly Sue , Stocco Andrea
Published: May 2023

Recent studies suggest that errors facilitate learning in certain conditions. Despite this, reinforcement paradigms dominate learning methods, subscribing to the narrative that errorless learning is the foundation of an ideal learning environment. If we continue to view learning from this restrictive perspective, we may fail to capture and apply the benefits of errors. In this paper, we investigate two potential mechanisms of post-error learning. Participants (N = 61) learned word pairs in either a study or error trial before taking a final test. Supporting past error learning literature, errors before a study opportunity led to better performance on a final test. Differences in reaction times between conditions support the theory that errors increase learning by acting as a mediator, or secondary cue, to the correct answer on subsequent tests.

Published: May 2023

The article examines the influence of lifestyle on the state of health of students of higher education of different years of study. The factors that encourage students of the first and fourth years of study to organize a healthy lifestyle have been determined. Aspects of a healthy lifestyle, which students strive to follow, are considered, because they consider them the most important for maintaining and strengthening health. The reasons for the use of drugs, alcoholic beverages and smoking have been established. Also, the peculiarities of students' observance of a rational daily regime and the use of a hardening system are determined.

The results of the student survey show that among the factors that could encourage students to organize a healthy lifestyle, the desire to maintain a physical shape and looks good as long as possible is in the first place among students of the 1st and 4th year. Self- realization in the profession is secondary for 1st-year students, and for 4th-year students - care for their health. In third place for 1st-year students is the acquisition of knowledge, skills and abilities to preserve and strengthen health, and for 4th-year students - the importance of health for the well-being and peace of their relatives and friends.

According to the results of the survey of students of the 1st and 4th courses, it was found that 100% of the 1st-year students and 92% of the 4th-year students strive to follow a rational daily routine. 70% of 1st-year students and 50% of 4th-year students consider it appropriate to use the hardening system. 88% of surveyed 1st-year students believe that parents and friends can encourage a person to lead a healthy lifestyle. Among the students of the 4th year, only 70% of them think so.

THE PRINCIPLE THAT THE LAND DOMINATES THE SEA IN THE CONTEXT OF SOUTH CHINA SEA DISPUTES: A CRITICAL APPRAISAL
Authors: Hamid Abdul Ghafur
Published: May 2023

According to the principle that the land dominates the sea, the land is always the basis for any claim of maritime entitlements. Without a land with a coastline or coastal front under its sovereignty, no state can claim any maritime entitlement. The land here includes not only the continental mainland but also islands which may generate the same maritime entitlements.  Nonetheless, certain claimants of the South China Sea have rejected or tried to bend the principle in furtherance of their respective claims. The main objective of the present paper, therefore, is to assess the status of the principle as customary international law and its application to the nine-dash-line claim of China and other claims based on maritime features such as atolls, coral reefs, shoals, and the like. The paper reviews the decisions of the international courts and tribunals on one hand and analyses the relevant provisions of the UNCLOS on the other. The paper also applies interpretative tools to reaffirm the meaning of Article 121 of the UNCLOS: the regime of islands. The paper concludes that the claim of historic rights in the nine-dash-line is not squarely in accord with the principle and that most of the claims on the South China Sea that are based on artificially built structures and land reclamation defeat the letter and spirit of the regime of islands, which is a manifestation of the principle that the land dominates the sea.

Objective of the Review: To present the available data on the impact of obesity on woman’s health and quality of life. Key Points. The term “metabesity” includes a range of conditions associated with obesity and its sequelae. From pathogenic point of view, it is an obesity-associated metabolic aberration: subacute inflammation, mitochondrial dysfunction, and changed gut microbiome. Together with a genetic component, the phenotypes of metabesity are mostly a result of sedentary lifestyle and unhealthy eating. Metabesity is associated with a number of both health- and life-threatening comorbidities, including arterial hypertension, cardiac failure, myocardial infraction, and stroke. Insulin resistance, hypertensive disease, advanced arteriosclerosis, dyslipidemia and fatty hepatosis are more frequent in obese people than in the general population. This literature overview presents a modern idea of the metabesity impact on the long-term health of a woman. Conclusion. Recently, forecasting and prevention of diseases affecting the quality and duration of life have been attracting more and more interest. Taking into account the regular changes in the gender component of the population with age, obesity and its impact on the health of women from various age categories are of special interest. Obesity increases the risk and overall cancer mortality. Metabesity affects hormonal homoeostasis in the female body and increases the risk of degenerative conditions, including dementia. Taking into account the genetic component, the strategies to tackle metabesity, including a campaign against sedentary lifestyle and unhealthy eating, should be initiated since early childhood. Lifestyle modification is the only proven way to manage/prevent metabesity and associated diseases. Keywords: metabesity, obesity, metabolic syndrome, female health, cancer, diabetes, insulin resistance.

Aim: Clinical and morphological evaluation of the effectiveness of the hysteroscopic metroplasty using the pulsed diode laser in case of the intrauterine septum. Design: Retrospective comparative study. Materials and methods. A comparative analysis of the effectiveness of the metroplasty, specific features of the course of the surgery, postoperative period, status of the endometrium and reproductive function was performed in 39 women (1st group) who underwent the surgery with the use of the pulsed diode laser and 19 patients (2nd group) who underwent bipolar electrosurgery. Results. When using the proposed method of metroplasty, the dissection of the intrauterine septum was statistically significantly more often optimal (82.05%) (p < 0.001). The morphological structure of the endometrium after metroplasty in patients of the 1st group significantly more often corresponded to the phase of the menstrual cycle (86.36%; p = 0.044) and was less often changed due to manifestations of perivascular fibrosis (12 (54.55%) of 22; p = 0.037). In most women of the 1st group, pregnancy ended in timely delivery — 15 (71.43%) out of 21 (p = 0.013). Conclusion. The proposed method of metroplasty is an effective and safe method of dissection of the intrauterine septum, which has a positive effect on reproductive function. Keywords: intrauterine septum, hysteroscopic metroplasty, reproductive function.

Materials and Methods: 749 women were examined (249 did not indicate the presence of somatic pathologies, 500 indicated them in their medical history and as current, 353 had currently experienced pathologies; mean age 41.9 ± 11.48 years) using the "Ways of Coping Questionnaire", "Method of Determining Individual Coping Strategies", S. Maddi's Hardiness test, SF-12. Results. Productive coping strategies were found to be characteristic of women with higher quality of life, while unproductive coping strategies were found to be characteristic of women with lower quality of life. Specific coping strategies were discovered that differentiate women with various diseases from healthy women. Women who reported different illnesses in their medical history or were currently experiencing them showed greater severity of unproductive coping strategies (resignation, dissimulation, confusion, distancing). Coping strategies specific to various diseases were identified. Conclusion. The obtained results were compared with those presented in the literature. They can be used to correct coping strategies that worsen well-being and are negatively associated with patient quality of life. Keywords: coping strategies, women, quality of life, somatic pathologies.

The aim of the research: to conduct an analysis and generalization of scientific publications on the issue of the patient-centered care implementation in clinical practice setting.
Results. The concept of a patient-centered care, proposed in the USA in the early 1990s, was subsequently used by the WHO in the development of the program for the development of the health care system in the 21st century. This approach shifts the focus from the traditional biomedical model, in which the doctor is given a priority role in decision-making to a model that establishes a partnership among practitioners, patients, and their families. Recent scientific publications identified eight principles of patient-centered care: respect for patient's values, preferences, and expressed needs, provision of information and education, emotional support to relieve fear and anxiety, involvement of family and friends, physical comfort and symptom`s relief, continuity and secure transition between healthcare settings, coordination of care, access to care. The implementation of a patient-centered care in clinical practice faces a number of difficulties, in particular, with regard to the influence of social, economic, financial factors, training of medical personnel and patient education. Another aspect is the heterogeneity of patients in terms of their ability to take a partnership approach and be involved in the decision-making process. Further clinical trials are needed to provide evidence for the practical use of the most effective approaches to patient-centered care implementation.
Conclusions: The patient-centered care has become a key element of the quality of medical care and assumes that the care provided should meet the individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions. The introduction of a patient-centered care requires appropriate medical education of doctors to improve communication skills and patient`s education for involve patients in the treatment process as partners.

Study Design: Retrospective cohort study.Purpose: To compare the relative value units (RVUs) per minute of operative time between primary and revision surgery for adult spinal deformity (ASD).Overview of Literature: Surgery for ASD is technically demanding and has high risks of complications and revision rates. This common need for additional surgery can increase the overall cost of care for ASD. RVU is used to calculate reimbursement from Medicare and to determine physician payments nationally. In calculating RVUs, the physician’s work, the expenses of the physician’s practice, and professional liability insurance. Cost effectiveness of surgeries for ASD have been evaluated, except for RVUs per minute compared between primary and revision surgery.Methods: Data were obtained from the American College of Surgeons National Surgical Quality Improvement Program database. Patients aged ≥18 years who underwent surgery for spinal deformity between 2011 and 2019 were identified and included. To ensure a homogenous patient cohort, those who underwent anterior-only and concurrent anterior-posterior fusions were excluded. Propensity score matching analysis was performed, and Mann-Whitney U test, Pearson chi-square test, or Fisher’s exact test were used to compare matched cohorts as appropriate.Results: A total of 326 patients who underwent revision surgery were matched with 206 primary surgery patients via propensity score matching. Demographic characteristics, comorbidities, preoperative laboratory values, and readmission and reoperation rates were not significantly different between groups. The revision surgery group had significantly higher mean RVUs per minute than that of the primary surgery group (0.331 vs. 0.249, p <0.001), as well as rates of morbidity and blood transfusion.Conclusions: Compared to primary surgery, revision surgery for ASD is associated with significantly higher RVUs per minute and total RVUs and higher rates of 30-day morbidity and blood transfusions. Readmission and reoperation rates are similar between surgeries.
Developing interdisciplinary research teams in neurosurgery: key elements to success in brachial plexus and peripheral nerve surgery

Published: May 2023

The highest-impact medical literature is increasingly produced by interdisciplinary teams. The field of neurosurgery, which involves complex pathologies and recoveries, is particularly amenable to interdisciplinary research approaches. However, research in the medical context regarding the characteristics of effective teams, as well as how to develop and maintain interdisciplinary teams, remains lacking. Here, the authors used the business literature to identify the characteristics of effective teams. They then used the University of Michigan Brachial Plexus and Peripheral Nerve Program, founded under the leadership of the late Dr. Lynda Yang, as a case study for how these principles can be applied to build and operationalize a successful interdisciplinary team. They suggest that these same techniques can be used to create interdisciplinary research groups in other areas of neurosurgery.

Водогосподарсько-екологічне районування та управлінні воднимиресурсами виконується за індукційними коефіцієнтами антропогенного навантаження на басейни річок (при відсутності радіаційного забруднення) і за величинами радіаційного забруднення водозборів та індукційними коефіцієнтами антропогенного навантаження. Районування допоможе швидко визначити, які окремі підсистеми або водойми знаходяться в порушеному природному стані, а також визначити, які зміни певних показників призвели до цього стану. Субпідрядність одиниць водогосподарсько-екологічного районування базується на збереженні єдності водного об’єкту, на території якого розв’язуються питання щодо регулювання, використання, управління і охорони водних ресурсів та створення екологічно безпечних умов на водозборі. Основу районування становить класифікація антропогенного навантаження на басейни річок заступенем екологічного ризику, яка має шість градацій. Виконанняводогосподарсько-екологічного районування дає змогу просторовооцінити і ранжувати басейни річок за ступенем екологічного ризику відносно рівня антропогенного навантаження з метою визначення черговості інвестиційних вкладень на природоохоронні заходи.

Published: May 2023

This paper describes the process of designing and prototyping a low-cost robotic platform based on existing equipment and projects that enable extracurricular STEM activities in Croatia and beyond. A robotic platform with a differential drive configuration was chosen for education from an early age due to its simplicity and a wide range of cheap and compatible components from which it can be made. From the aspect of integration into extracurricular or curricular activities, the BBC micro:bit ecosystem was considered, enabling block-based visual programming. Components with printable parts make up the assembly of the educational robot. The main steps in designing and creating a robot prototype are presented, which consist of the modelling, 3D printing of robot parts, and assembly into a functional system. After several stages of testing, an interactive workshop was held with 7th-grade primary school pupils. Further work is planned to create educational material for extracurricular STEM workshops.
