Single motherhood: A growing sociological and economic existential concern for global communities
Authors: Johnnie Namwako Halwiindi
Published: May 2024

Single motherhood as a living condition has become one the greatest alternative family structures in the world, only second to couples living together. For the case of poorer communities, the challenge seems to be greater because women are among the most affected members of society as compared to their male counterparts, when it comes to social and economic privileges. These women who are often left to fend for their families after the death of their husbands, divorced and some never married, struggle with meeting their economic and parental obligation. This causes a lot of challenges that include but are not limited to, homelessness, school dropouts, prostitution, early pregnancies and delinquent behaviors in children, etc. The premise of this article argues the case for single mothers as an express necessity and concern for society, church, and government. The single mothers, being found in these circumstances are exposed to suffering through neglect but also not given due attention as far as economic privileges are concerned. Purpose: whereas it is clear that the world is rallying on the agenda for couples and marriage as the norm for raising children in an ideal environment, it has become increasingly undeniable as to the number of marriages that are ending some in divorce and other societal challenges. Annually as others have posited, 30% of all marriages worldwide end in divorce, others lose their spouses to death and others have never been married before. This article seeks to create an appreciation of the current situation which is not only conspicuous but also undeniable. For societies faced with challenges of economic inequality between males and females, it has become a necessity to create awareness in bridging the knowledge gap in society and provide solutions for the challenge.

Published: May 2024

Background: Diffuse alopecia is a psycho-social stressor on human life. As iron is involved in crucial physiological processes within the hair follicle, iron deficiency is suspected to disrupt hair growth. Chronic telogen effluvium (CTE) and female pattern hair loss (FPHL) are the most common causes of chronic diffuse alopecia in females. In both conditions, low iron store have been considered as a possible contributing factor. Materials and Methods: This was a hospital-based case control study, conducted in the Department of Dermatology and Venereology, Bangabandhu Sheikh Mujib Medical University (BSMMU) to evaluate the association of serum ferritin with chronic diffuse alopecia in female patient. Results: The mean age of the females with chronic diffuse hair loss was 26.83±7.78 year and 92.9% females had serum ferritin level <30 ng/ml. The mean serum ferritin level in females with chronic diffuse hair loss, CTE and FPHL were 16.3±11.61 ng/ml,12.35±7.15 ng/ml and 20.25±16.07 ng/ml respectively, which were lower than control 54.37±26.07 ng/ml. A highly significant (p<0.001) difference found in the mean serum ferritin level between the groups. In females with CTE, 42.5% had serum ferritin level < 12ng/ml (iron deficient) and 37.5% had 12-20 ng/ml (iron depletion). In females with FPHL, 23.3% and 30% patients had serum ferritin level <12 ng/ml and 12-20ng/ml respectively. Conclusion: This study found the level of serum ferritin were significantly low in females with chronic diffuse hair loss both in chronic telogen effluvium (CTE) and female pattern hair loss (FPHL), indicating there is a definite association of decreased iron store and diffuse hair loss.

Introduction: The decision to proceed with surgical intervention is often difficult in pregnant women, particularly in emergency contexts. Opting for laparoscopic surgery in pregnant women is even more challenging. Concerns during laparoscopic procedures include potential fetal injury, reduced uterine blood flow due to pneumoperitoneum, and fetal acidosis. The objective of our study is to evaluate the feasibility and morbidity-mortality of emergency laparoscopy in pregnant women. Materials and Methods: This is a descriptive and prospective study conducted between February 2018 and October 2021, involving 337 patients who underwent laparoscopic surgery for acute non-traumatic abdominal emergencies. Results: Among the 190 female patients operated on, 18 patients (9.47%) were pregnant: 8 (44.5%) had acute appendicitis, 7 (38.9%) had acute lithiasic cholecystitis, 2 (11.2%) had ovarian cyst torsion, and 1 (5.6%) had an appendiceal abscess. This laparoscopic management was performed across different gestational ages. The mean gestational age of our patients was 15 ± 14 weeks of amenorrhea (minimum 7 weeks, maximum 29 weeks). The mean operative time for the surgical interventions in these pregnant women was 61.2 minutes ± 20.16 minutes. No intraoperative complications or incidents, no conversions, and no abortions were recorded. Conclusion: Laparoscopy can be safely used to manage acute non-traumatic abdominal emergencies during pregnancy.

Objective Due to the high frequency of depressive symptoms associated with breast cancer, it is crucial to screen for depression in breast cancer patients. While numerous screening tools are available for depression in this population, there is a need for a brief and convenient tool to enhance clinical use. This study aims to investigate the psychometric properties of the Patient Health Questionnaire-9 (PHQ-9) in patients with breast cancer.Methods Patients with breast cancer (n=327) who visited the Breast Cancer Clinic were included in this study. The reliability of the PHQ-9 was analyzed by Cronbach’s α, and the construct validity of the PHQ-9 was explored by factor analysis. The concurrent validity of the PHQ-9 was evaluated by Pearson correlation analysis with the Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS).Results The values of Cronbach’s α ranged from 0.800 to 0.879 was acceptable. The exploratory factor analysis revealed that the one-factor model and two-factor model of the PHQ-9 explained 46% and 57% of the variance, respectively. The PHQ-9 were significantly correlated with those of HADS (r=0.702, p<0.001) and PSS (r=0.466, p<0.001). Consequently, the PHQ-9 demonstrated acceptable reliability and validity in breast cancer patients.Conclusion The findings of this study indicate that the PHQ-9 exhibits acceptable reliability and validity in patients with breast cancer. The convenience of this brief self-report questionnaire suggests its potential as a reliable and valid tool for assessing depression in breast cancer clinics.

Published: May 2024

Objective The rising prevalence of mild cognitive impairment (MCI) has spurred interest in innovative cognitive rehabilitation approaches, including serious games. This review summarizes randomized clinical trials (RCTs) exploring the impact of serious games on MCI patients.Methods We conducted a comprehensive data search using key terms such as “gamification,” “digital therapy,” “cognition,” “mild cognitive impairment,” and “Alzheimer’s disease.” We exclusively considered published RCTs, excluding animal studies and basic research.Results We identified eight RCTs. Four RCTs examined the effects of serious games using cognitive training for MCI patients. Notably, one study found that non-specific training (Nintendo Wii) significantly enhanced cognitive function and quality of life compared to cognition-specific computer training (CoTras). Among the remaining three RCTs, one specifically demonstrated that personalized serious game-based cognitive training yielded superior cognitive outcomes and reduced depressive symptoms. One RCT focused on serious games incorporating physical exercise, highlighting the effectiveness of kinetic-based exergaming in enhancing overall cognition. Three RCT focused on combined cognitive training and physical exercise. A double-blind RCT revealed that progressive resistance training or standalone physical exercise outperformed the combined approach in improving executive function and global cognition. Two additional RCTs reported positive outcomes, including improvements in cognitive function and electroencephalogram patterns associated with game-based interventions.Conclusion Serious games, whether focusing on cognitive training, physical exercise, or a combination of both, have potential to improve cognitive and functional outcomes in individuals with MCI. Further research and standardization of protocols are needed to better understand the full potential of serious games in MCI.

Published: May 2024

Objective Early detection and intervention of developmental disabilities (DDs) are critical to improving the long-term outcomes of afflicted children. In this study, our objective was to utilize facial landmark features from mobile application to distinguish between children with DDs and typically developing (TD) children.Methods The present study recruited 89 children, including 33 diagnosed with DD, and 56 TD children. The aim was to examine the effectiveness of a deep learning classification model using facial video collected from children through mobile-based application. The study participants underwent comprehensive developmental assessments, which included the child completion of the Korean Psychoeducational Profile-Revised and caregiver completing the Korean versions of Vineland Adaptive Behavior Scale, Korean version of the Childhood Autism Rating Scale, Social Responsiveness Scale, and Child Behavior Checklist. We extracted facial landmarks from recorded videos using mobile application and performed DDs classification using long short-term memory with stratified 5-fold cross-validation.Results The classification model shows an average accuracy of 0.88 (range: 0.78–1.00), an average precision of 0.91 (range: 0.75–1.00), and an average F1-score of 0.80 (range: 0.60–1.00). Upon interpreting prediction results using SHapley Additive exPlanations (SHAP), we verified that the most crucial variable was the nodding head angle variable, with a median SHAP score of 2.6. All the top 10 contributing variables exhibited significant differences in distribution between children with DD and TD (p<0.05).Conclusion The results of this study provide evidence that facial landmarks, utilizing readily available mobile-based video data, can be used to detect DD at an early stage.

Published: May 2024

Objective We aimed to classify subgroups of suicidality among adolescents and identify the influencing factors of the classification of these latent classes.Methods Suicidal thought, plans, and attempts as well as the feelings of sadness/hopelessness and loneliness were utilized as indicators to derive the suicidality classes. Additionally, health behaviors, such as dietary habits, physical activity, experiences of violence victimization, sexual activity, and deviant behavior, along with demographic factors, such as sex, school year, grades, and household income, were considered as influencing factors. The analysis utilized data from the 18th Youth Health Behavior Survey (2022) conducted by the Korea Disease Control and Prevention Agency, involving 51,850 middle and high school students.Results The findings revealed three latent classes of suicidality among adolescents: “active suicidality,” “passive suicidality,” and “non-suicidality.” The influencing factor analysis indicated that all factors, with the exception of high-intensity physical activities, significantly influenced the classification of latent classes of suicidality. Notably, walking exercise and the frequency of exercise during physical education class were found to be factors that differentiated between active and passive suicidality within the suicidality classes.Conclusion This study employed nationwide data to identify the exhibited suicidality classes among adolescents and tested the influencing factors necessary for predicting such classes. The study’s findings offer valuable insights for policy development in suicide prevention and suggest the need for developing customized interventions tailored to each identified class.
Meaning-oriented approach to the description of semantic fields in Russian as a foreign language classes (by the example of the semantic field “Love”)
Authors: Epifanova Valentina Valerjevna
Published: May 2024

The article provides an overview of Russian linguo didactic works devoted to the adaptation of the system of typical meanings in the form of lexical functions (in the terminology of I. A. Melchuk and A. K. Zholkovsky) to practical classes in a foreign language audience. The aim of the conducted research is to adapt the system of typical meanings to the presentation and practice of lexical material of the semantic field “Love” in Russian as a foreign language classes (RFL). The novelty of the conducted research lies in the development of the theory of using the system of typical meanings in the educational process in RFL classes from the standpoint of not only stable, but also word-formation means. This approach makes it possible to reassess the prospects for studying lexical compatibility, idiomatics and morphological modifications of Russian words in the aspect of RFL. Own materials are proposed for teaching foreign learners to combine and modify Russian words from the standpoint of the onomasiological approach (from meanings to ways of expressing them) within the semantic field “Love”. As a result of the research, the most frequently used semantic parameters describing love relationships between their participants are demonstrated, and the most universal ways of expressing a particular typical meaning are listed from the standpoint of receptive and productive speech actions. The approach presented in the work allows foreign students to successfully carry out the process of speech creation in Russian with a more accurate transmission of the given meanings, significantly increasing the language competence of the learners.

Исследован износ нормализованных (N) и закаленных на двухфазную структуру (мартенсит + феррит) (DP) низкоуглеродистых (0,08 % C) и среднеуглеродистых (0,42 % C) сталей при воздушно-струйной эрозии под действием частиц оксида алюминия под углом удара 15° и 90°. Двухфазная структура DP сталей с разным количеством мартенсита получена путем выдержки при температуре межкритической области 745 °C в течение различного времени (2, 3, 4 мин) с последующей закалкой в воде. Показано, что твердость и предел прочности низко- и среднеуглеродистых DP сталей повышаются с увеличением содержания мартенсита в структуре, а скорость установившейся эрозии уменьшается с увеличением количества мартенсита и угла удара. Установлено, что при эрозии изменение структуры поверхности происходит за счет растрескивания, образования кратеров и срезания при угле удара 90°, тогда как при 15° наблюдаются царапание и выкрашивание.
The Syndrome of an Emigrant: Memory, Trauma, Longing, and Loss in the Art of Józef Czapski
Authors: Kossowska Irena
Published: May 2024

This article addresses the multilayered thematic area focused on the impact of trauma, caused by war and political oppression, on the attitudes of artists who followed combat trails and migration routes to ultimately settle far from their homeland. What I consider particularly challenging in this field of study is to find an answer to the question: why did some of the forcefully displaced artists manage to integrate with the art scene of their final destination, while others preferred to attain their position on the cultural margins of the new locality? The best exemplification of these complex issues is the biography of Józef Czapski (1896-1993), a Polish writer, essayist, art critic, and painter, who fought in the ranks of the Polish army on the fronts of World War I and World War II, and, eventually, permanently settled in France. I argue that it was the wartime and the hell of migration that caused Czapski’s inability to fully assimilate in the Parisian art world, and stimulated his aversion to avant-garde progressivism and innovative experimentation. My analyses reveal that his paintings epitomise remnants of collective and individual trauma, an overwhelming sense of loss, and a ‘residue’ of painful experiences resulting from expulsion and exile.

Generative Urban Design in the Field of Infrastructure: An Optimizing Solution for Connecting Fier and Vlora County by a 600 m Bridge over Selenica River, Albania
Authors: Rusi Ilda , Alliaj Albi
Published: May 2024

The way we think about infrastructure is being completely changed by parametric and generative design. Meanwhile the contemporary urban planning process is often viewed as a complicated and fragmented workflow. The main goal is to optimize solutions with tens of thousands of variations while concurrently taking into consideration various limits. This Paper will discuss and demonstrate the use of a generative urban design framework at the local scale. Although relevant to infrastructure, generative design is not limited to architecture. And on the other hand, the construction sector is becoming more specialized and complex. The close cooperation between structural engineers, architects, urban planners and other stakeholders is a major driving force behind modern projects. The building site is cut off from architects and engineers, particularly in the digital age. To ensure a three-dimensional scope of work, digital models are therefore necessary. The difficulty is that the structural model and architectural model do not match up exactly. A generative design is therefore explained in the case of a bridge design. Bridges are effective structures that provide a variety of topologies, materials, and geometries. This paper examines how the geometry and topology of a 600 meters long bridge can bring an optimal solution for connecting two nearby counties, Fieri and Vlora. The performance of the bridge can be examined by altering the geometrical parameters in addition to the topology. By adding more design factors and offering a fresh method for bridge optimization, the study aims in further developing the initial parametric model. Since the process of changing the design is quite quick and the analysis is displayed instantly, using parametric design to study alternative options for bridges could be highly helpful to designers. Keywords: generative design, bridge, geometry, typology, optimization, deflection.

Published: May 2024

This research discusses students' perceptions of mathematics learning based on their brain dominance. Descriptive qualitative methods were used with questionnaires and interviews. The research subjects were 26 students who filled out a questionnaire in the form of a brain dominance questionnaire, with details of 6 students who were interviewed in depth. Data analysis was carried out through discourse analysis of the interview results by considering the respondent's environmental context. The results of the research show that there are differences in perception between students who are right and left brain dominant and students who use both equally. Some students have different ease and difficulties in learning mathematics, as well as different views about the benefits of this material in everyday life. Apart from brain dominance, there are several other factors that influence students' perceptions, including the way teachers teach and the learning environment. Knowing students' brain dominance is important, because it can help teachers determine how to teach material appropriately so that it gets a good perception for all students, whether they are right-brain dominant, left-brain dominant, or those who tend to be balanced. In conclusion, students' perceptions of mathematics learning can be different, depending on their brain dominance.
