Authors: Roszko-Wójtowicz Elżbieta , Dańska-Borsiak Barbara , Grzelak Maria M. , Pleśniarska Aleksandra
Published: January 2023

Research background: Discussions on the state of the economy in times of crisis focus not only on maintaining or improving innovativeness, but also on the emergence of new dimensions of this phenomenon and changing the significance of individual determinants of innovativeness. Innovativeness is a complex, multidimensional and difficult to measure phenomenon, which implies the need to select various indicators and methods for its assessment. Synthetic measures of innovativeness are widely used in comparative analyses, in particular presenting results in international or interregional cross-sections. The degree of innovativeness should also be assessed at different levels of economic aggregation. The lower the level of aggregation, the easier it becomes to capture the specific determinants of the increase in innovativeness of a given area.
Purpose of the article: The main aim of the paper is to attempt to measure the relationship between expenditures and results of innovative activities for NUTS-2 regions of the Visegrad Group countries. Three variables were adopted to describe the effects of innovative activity: PCT patent applications per billion GDP (in PPS), trademark applications per billion GDP (in PPS) and public-private co-publications per million of population.
Methods: The study covered 37 NUTS-2 regions of the Visegrad Group countries in the years 2014?2021. From the point of view of the purpose of the paper and the need to search for the relationship between expenditures on innovative activity and the results of this activity, it is worth emphasizing that the use of static and dynamic econometric models proved to be a substantively correct solution leading to the formulation of clear conclusions.
Findings & value added: The conducted research confirmed that business R&D expenditure on GDP has a positive effect on inventions expressed by patents and trademarks, especially in the long run. In addition, the literature review and empirical analyses indicate that the main determinants of innovativeness (both before and during the pandemic) are the expenditures of economic entities on R&D, competences expressed by the level of education or participation in tertiary education, as well as the number of ICT specialists and the percentage of people employed in science and technology. Despite the deterioration of many macroeconomic indicators in the countries of the Visegrad Group, the expenditures of the business sector on R&D in most regions did not decrease between 2019 and 2021. The added value of the paper is the presented research procedure, which can be used in analyses of innovativeness also for other groups of regions.

Published: January 2023

The Eurasian tree sparrow (Passer montanus L.) known as both pest and predators; in the urban area, it is considered a pest because of its droppings, feathers, and nests around the house. Meanwhile, in rural areas, it is considered both pests and predators because their diets are small insects and small grains like a grain in the rice field. This study aimed to determine the daily consumption rate of sparrows on grain; their preferred food; identify the adaptability; and the role of sparrows in urban and rural areas. Feeding ability test using the no-choice baiting method. Food preference test using the choice baiting method. The adaptability and role of sparrow data are obtained through location determination and direct observation in the field. The results show that the consumption rate of individual sparrow is ten percent of body weight. The most preferred food for sparrow is yellow mealworm, followed by millet, cricket, foxtail millet, rice grain, and corn. The Eurasian tree sparrow is not considered a pest on rice fields. The presence of the sparrow in urban areas is less than in rural areas. Both in urban and rural areas, more sparrows were seen or found in the morning than in the afternoon. Sparrows can adapt well in rural and urban areas because the environment provides open area and house building. In urban areas, sparrow is considered urban pests; meanwhile in rural areas they potentially considered a pest on barley and millet, and predators on small insects.

Alternaria solani Sor. is one of destructive pathogens in solanaceous plants including tomato. Bacteria and yeast isolated from water extract of organic matters are potential as biological control agents of plant pathogenic fungi. Mechanisms of antagonism of bacteria and yeast can be through antibiosis. This study was conducted to examine the abilities of culture filtrate and volatile compounds produced by antagonistic bacteria and yeast isolated from compost and vermicompost teas to inhibit the growth of A. solani in vitro. The experiments were arranged in randomized complete design with four replications. The culture filtrate experiment applied well diffusion method, while the volatile compound effect experiment used petri dish sandwich method. The results showed that the culture filtrates of four bacteria and three yeast isolates inhibited the growth of A. solani in vitro by 16.6-87.5%. The highest inhibition level was showed by KSB4 isolate (Bacillus subtilis), a bacterial isolate from cow manure compost tea. In the volatile compound effect experiment, the tested bacteria and yeast isolates inhibited the pathogen growth by 31.3-75.2%, with the highest inhibition was showed by KcB3, a bacterial isolate from vermicompost tea. The isolate that its culture filtrate and volatile compounds both showed high inhibition level (62.7% and 87.5%) on A. solani growth was KSB4 isolate (B. subtilis).

Published: December 2022

Background: Sickle Cell Disease (SCD) is most common genetic disorder and its prevalence in sub-Saharan Africa is increasing. Despite increased survival rates, experiences of adults living with SCD in Tanzania is not well explored. This article provides perceived causes of pain crisis, pain self- management approaches and psychosocial implication of SCD. Aim: This study aimed at exploring experiences of adults living with SCD regarding pain triggering or aggravating factors; self-management for pain; psychosocial-economical implication of SCD and coping mechanism used by individuals living with SCD Methods: A qualitative study design was chosen using in-depth interviews with adults living with SCD to explore their experience of living with SCD. Fifteen adults aged 18 years and above living with SCD were interviewed. Data were analyzed by using content analysis approach. Findings: Four categories emerged that described experiences of individuals with SCD. The four categories are; “Pain Triggering and Aggravating Factors” describing participants’ perceived factors causing pain in SCD; “Self-care remedies for the pain” referring to participants’ methods for self-management of pain; “Psychosocial-economic impact of illness” referring to participants’ experience of implication of illness on social and economic life and “Dealing and coping with illness” referring to experience of participants on management and coping strategies used to live with the illness. Conclusion: Individuals with SCD experiences several episodes of pain that affect their quality of life. Pain episode can be triggered or aggravated by various factors. Several approaches are used by individuals with SCD to self-manage the pain including taking rest, drinking plenty of water or using pain relieving medication. Care for individuals with SCD should be comprehensive and include proper management of pain, health education on home-based intervention for sickle cell pain, supportive services to deal with psychosocial implications of SCD and improving coping strategies to live with the illness.

Authors: J Kibesa Saraphina , W Kitua Yona , W Kitua Daniel
Published: December 2022

Background: Antenatal Care (ANC) coverage is a key determinant of maternal and perinatal morbidity and mortality. Low utilization of ANC services and high Maternal Mortality Ratio (MMR) have been reported in the East African Region. Due to the paucity of information on the determinants of ANC utilization in this region, we conducted the study aiming at exploring factors influencing the utilization of ANC services. We further sought opinions that will aid the improvement of utilization of ANC services. Methods: A triangulation mixed-method study was conducted in August 2021 among forty-five women and ten healthcare providers in a selected health center located in Dodoma Urban District, Tanzania. Information was gathered using semi-structured questionnaires and in-depth interviews. Quantitative data were analysed using IBM SPSS Statistics. The relationship between the outcome variable and the predictor variables was assessed by either the Chi-square test or Fisher’s exact test and a p value<.05 was considered statistically significant. Manual thematic analysis was used for qualitative data after thorough transcript and documentary reviews. Results: Almost half (48.9%) of the interviewed women attended ANC services at least once during their last pregnancy. Women who reported having a low income and those who spent more than an hour reaching the health facility had poor ANC attendance (p value<.05). The main themed factors that negatively impacted ANC utilization included cultural practices and gender norms, poor communication between partners, and long waiting time at the ANC clinics. Conclusion: Utilization of ANC services was found to be low among women living in Dodoma Urban District. ANC attendance varied with the level of income and the time women spent reachingt the health facility. Cultural practices and gender norms, communication between spouses, and service waiting time were mentioned to influence ANC attendance. Recommendations: Public and private sectors should invest in maternal health, provide affordable services and formulate strategies to improve the accessibility of ANC services. Interventions should target women of low socio-economic class and those living in remote areas. Moreover, schemes to address the sociocultural barriers to ANC utilization need to be formulated.

Published: December 2022

Cassia sieberiana is a tree of 8 to 10 meters in height, used to treat various diseases including malaria, dysmenorrhea and many others. Our objective is the scientific valorisation of Cassia sieberiana, a plant used in therapy in Ivory Coast, by evaluating the anti-inflammatory activity of the bark of the root of Cassia sieberiana. To do this, the phytochemical study was carried out in order to determine the main chemical constituents with therapeutic potential, then the acute toxicity by gavage and intraperitoneal injection were carried out and finally the anti-inflammatory activity was verified.
The phytochemical study revealed the presence of sterols, polyterpenes, polyphenols, flavonoids, catechic tannins, saponosides and alkaloids. As for the toxicity study, it allowed us to determine by per os route an LD50 > 5000 mg/kg PC, and by IP an LD50 = 524, 807 mg/kg PC graphically and by calculation an LD50 = 400 mg/kg PC. The anti-inflammatory activity of the aqueous extract of Cassia sieberiana at a dose of 200 mg/kg CP is higher than that of diclofenac at a dose of 10 mg/kg CP from the 3rd to the 6th hour of the experiment. Cassia sieberiana is non-toxic by oral administration but toxic by intraperitoneal injection. Cassia sieberiana also has anti-inflammatory activity.

Authors: Hossen Muhammad Ilias , Wang Chaoxia
Published: December 2022

The application of 3D printing technology has been relatively slow in the fashion industry. Both in the fashion industry and in 3D printing, the material used plays a very important role. In this direction, thermoplastic polyurethane (TPU) is one material that has started to grab the attention of researchers, producers, and customers. While many have studied 3D printing technology using thermoplastic polyurethane material in the fashion industry from different perspectives, fewer researchers have addressed the actual adoption of thermoplastic polyurethane based 3D printing in the fashion industry. Thus, the present research has been focused to propose an adoption model for thermoplastic polyurethane based 3D-printed fashion clothes. Factor analysis was conducted to find and analyse the most relevant factors. Further exploratory factor analysis was conducted to test the proposed model. The study proposed a model for adoption based on four factors: motivation to buy, customer attitude, and the challenges and benefits associated with the adoption of thermoplastic polyurethane based 3-D printed fashion clothes.

Authors: Zhang Jingnan , Zhang Yi , Cui Rongrong
Published: December 2022

This paper aims to discuss the artistic characteristics of traditional cheongsam and the transformation that has taken place in cheongsam textile design in the Republic of China. By analysing a collection consisting of 259 traditional cheongsam material samples in various museums such as the China Silk Archives in Suzhou, we explored the transformation of cheongsam textile design during the Republic of China from the perspective of Eastern and Western art cultural exchanges and explored the spread of Western artistic thought in China. Our research shows that, firstly, with the development of industrialization, the traditional cheongsam textile business absorbed new design concepts; secondly, in terms of material selection and pattern style, it widened the range of fabrics used and broke the monotony of traditional Chinese patterns. Moreover, it reduced connotations of social class implied by traditional textile design. Finally, these textile designs reflect the progress that has been made in the development of this artistic trend and the cultural fusion of Eastern and Western arts during the Republic of China.
Research on the Method for Determining the Interaction of Cotton With the Working Bodies of Cotton Gins
Authors: Sailov Rahib Aqaqul
Published: December 2022

A theoretical regularity of the general behaviour of raw cotton as a porous medium in the technological processes of its mechanical processing has been substantiated for the first time. The speed of sound in a porous cotton medium has now been determined. The effect of additional force stresses inside the cotton medium caused by the filtration of the air component from cotton raw materials during the introduction of the working body, has been disclosed. A generalized equation that describes the force stress in a cotton medium when exposed to a variety of shapes of working bodies of cotton machines has been worked out. A method for calculating the damage to seeds and cotton fibers caused by their interactions with the working bodies of processing machines has been proposed.

The resultant theory that describes the stress state of cotton raw materials during processing allows us to use it practically to solve all important issues pertaining to the damage of fiber and cotton seeds that occur by using technological solutions in primary processing of cotton operations.

The study aimed to assess the impact of isolation and quarantine on the frequency of registration and the treatment of fractures of the proximal femur in Kazakhstan in the context of the COVID-19 pandemic in 2020 (compared to the pre-pandemic period).

This retrospective observational comparative study included all primary patients with injuries (the code S72) in the period 2019–2020 according to the national register.

In 2020, the number of S72 fractures was 6.6 % higher compared to 2019. In comparison with 2019, in 2020 the number of bed-days of patients was reduced to 7.1±3.8 days (p≤0.001). Both in 2019 and in 2020, the number of women predominated among all patients (p ≤ 0.05). The frequency of conservative treatment in 2020 compared to 2019 was increased from 26.6% to 35.6%, while the surgical procedure for internal fixation was reduced to 34.2% in 2020. In 2020, the highest number of cases among women with S72 fractures cases were recorded in the age groups 60–74 years and 75–90 years. In 2019 in female patients (42%) with S72 cases were registered in the age group 75–90 years.

The incidence of fractures of the proximal femur did not change significantly in 2020 compared to 2019. However, the number of conservative treatment methods has increased along with the decrease in the frequency of surgical interventions. We observed the growth of the frequency of non-surgical treatment methods in 2020 that might impose the possible risks of mortality of these patients in the long term after conservative treatment.

Published: January 2023

It is known that during operation, the aircraft construction materials are exposed to significant mechanical loads and changes in temperature for a very short period of time. All this leads to various defects and damages in the aircraft assemblies and units that need to be inspected for the safe operation of the aircraft, their assemblies, and units. In some cases, the implementation of inspection or diagnostic is accompanied by the emergence of technical difficulties caused by the large size of the aircraft assemblies or units and limited access to their local places. Under such conditions, ensuring the possibility of diagnosis in hard-to-reach places of the object becomes especially important. The problem can be solved by applying wireless technologies. It allows spatial separation of the probes and the signal processing units, which simplifies the scanning of the surfaces of the large assemblies and units in hard-to-reach places. In this article, the description of the developed wireless system of eddy current inspection for aircraft structural materials is given. Experimental results of object scanning are given in the form of a distribution of the values of probe signal informative parameters (amplitude, frequency and decrement) along the object coordinates.

Published: January 2023

Predecir el comportamiento hidrológico en cuencas hidrográficas compuestas por ecosistemas altoandinos que tienen una variedad de climas, con geología compleja, topografía muy variada y suelos con alto contenido de materia orgánica generadoras de una cobertura vegetal muy heterogénea es muy difícil, y si a ello se adiciona la escasez de información hidrométrica en las redes hidrográficas se genera gran incertidumbre al planificar el aprovechamiento del recurso hídrico. La tendencia predominante para la predicción es a través de modelos hidrológicos que relacionan precipitación y escorrentía, los cuales requieren información histórica no disponible en la mayoría de los casos. La aplicación de la técnica de redes neuronales artificiales, en contraste, permite disponer de una metodología adaptable a la información disponible en cada cuenca para analizar la relación entre precipitación y escorrentía, y gracias a su robustez se pueden obtener resultados con gran precisión. El objetivo de esta investigación fue estimar y predecir los caudales promedio mensuales para la cuenca del río Crisnejas, ubicada en la región norte de los Andes peruanos; para ello se contó con registros históricos de 12 estaciones meteorológicas y una estación hidrométrica, utilizando datos de caudal, precipitación, temperatura e índice de vegetación de diferencia normalizada (NDVI), mediante una red neuronal artificial del tipo perceptrón multicapa, con bondad de ajuste del 81 %. Luego, con el registro generado de caudales, se entrenó otra red del tipo recurrente para predecir caudales medios mensuales de ocho años con una bondad de ajuste del 71 %.

Published: January 2023

El análisis de frecuencias (AF) permite estimar magnitudes de los datos máximos anuales de crecientes y lluvias diarias asociadas con bajas probabilidades de ser excedidas. Tales estimaciones o predicciones permiten el diseño hidrológico de las obras hidráulicas de aprovechamiento o protección. El AF comprende cinco etapas: (1) verificación de la aleatoriedad de los datos; (2) adopción de una función de distribución de probabilidades (FDP); (3) ajuste de la FDP; (4) evaluación del ajuste logrado, y (5) selección de los resultados. En este estudio se exponen las bases teóricas de la distribución Kappa de cuatro parámetros de ajuste (u, α, k, h) obtenidos a través del método de los momentos L, que se describe con detalle. La distribución Kappa, cuando su segundo parámetro de forma h toma valores de -1, 0 y 1 reproduce a las distribuciones Logística Generalizada (LOG), General de Valores Extremos (GVE) y Pareto Generalizada (PAG). Se procesaron tres registros conjuntos de crecientes anuales de gasto pico (Qp) y volumen escurrido (Vol), dos registros anuales de Qp y tres de precipitación máxima diaria anual. A cada uno de los 11 registros procesados se les ajustaron cinco distribuciones: Kappa, la que reproduce según el valor de h (LOG, GVE o PAG); Log-Pearson tipo III; Log-Normal, y Wakeby. La calidad estadística de cada ajuste se cuantificó con el error estándar de ajuste y el error absoluto medio. Las conclusiones destacan la similitud de los resultados (errores y predicciones), en los 11 registros procesados y sugieren la aplicación sistemática de la distribución Kappa, para complementar las de aplicación bajo precepto y las de uso generalizado.

Introduction. Prostate cancer (PC) is one of the most common cancers among men over 50. Nowadays in Ukraine, the number of new cases of PC tends to increase according to statistics.

Objectives. The aim of the study is to identify the main problems in the life quality of patients with PC (C61) to optimize medical care for them.

Methods. The main aspects of the quality of life of PC patients are studied by means of EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires.

Results. In Ukraine, as of the pre-war period (November 2021 – February 2022), the quality of life of patients with PC amounted to 52.31 on a 100-point scale. The worst indicators within the functional scale QLQ-C30 belonged to the subscale “Role functioning” (65.44). According to the QLQ-C30 symptoms scale, the highest score among the complaints of Ukrainian patients is fatigue (48.58). Given the results of our research on the QLQ-PR25 symptom scale, patients with PC were the most worried about “Urinary symptoms”, with a score of 38.54 out of 100. According to the functional scale QLQ-PR25, the worst indicators were for “Sexual activity”, which is equal to 32.22 points on a 100-point scale.

Conclusions. It is important to create socio-psychological support for patients with PC and their families, which will include the development and implementation of standardized psychological care at all stages of diagnosis, treatment and rehabilitation.

Introduction. The presence of a connection of metabolic syndrome (MetS) with working conditions in various professional groups dictates the necessity to use diagnostics of its presymptomatic phase in the practice of occupational medicine.
The aim was to analyze the indices of anthropometric screening and blood lipid spectre among footwear industry workers with the aim of detecting early metabolic disorders..
Methods. It was conducted a cross-sectional study of 200 footwear industry workers: 119 male (59.5%) and 81 female (40.5%) aged 25 to 62. All workers were divided into groups according to their professional working experience: under 5 years, 6-14 years, 15-21 years.Anthropometric profile indexes were determined: body height (BH), body weight (BW), waist circumference (WC) and hip circumference (HC), body mass index (BMI), waist-to-hip ratio (WHR). Biochemical indicators of the lipid body balance were assessed by total cholesterol (TCH), triglycerides (TG), high density lipoprotein cholesterol (HDL CH), low density lipoprotein cholesterol (LDL CH), atherogenic coefficient (AC).
Results: Visceral obesity was detected among 60.56% of female workers and 30.91% male workers. It has been found that the increasing tendency of WHR was associated with the increase of working experience. The share of workers with normal body weight according to BMI accounts for 39.7-41.18%.
Lipid metabolism indices among workers with working experience under 5 years do not differ from referent norm and are characterized as dyslipidemia in the experience group of 15-21 years. The signs of MetS development were detected in 5.0-5.26% (experience group under 5 years), 10.7-11.1% (6-14 years), and 23.5-31.8% (15-21 years) of footwear industry workers. It was higher in male workers (18.3%), than female (11.7%).
Conclusions. Professional factors in footwear industry increase the risk of developing MetS components. Inclusion of anthropometric and lipid statuses assessments into the monitoring of health state will help to detect individuals with early dysmetabolic disturbances and to develop preventive instruments directed at saving metabolic health of workers in the branch.
