Authors: Alloghani Maryam Mubarak , Baig Mirza R. , Shareef Alawadhi Uhaila Mohammed
Published: March 2024

Objective: Post-partum depression (PPD) has been reported in about one-seventh to one-tenth of women. The aim of this study is to identify the demographic, obstetrics, social, and psychological risk factors of PPD among the eastern region of the United Arab Emirates.

Method: A community-based cross-sectional study was performed on 200 women who had a recent singleton pregnancy and delivered newborn within past six months via convenience sampling and email snowballing. Several demographics, obstetrics, social, and psychological factors of the respondents were assessed using a survey form. The Edinburgh depression rating scale (EDRS) was used for the identification of women with possible PPD. Descriptive statistics were utilized for the representation of demographic variables, whereas Chi-square test was employed to assess categorical variables. Also, logistic regression was applied to evaluate the association of investigated variables and PPD.

Results: The median EDRS score amongst the study participants was found to be 11 (0-26). The prevalence of PPD was found to be 57% in the studied population. Significant differences were observed in the adverse life events, emotional supports, marital conflicts and history of depression of the participants with and without PPD (P < 0.01). The risk factors significantly associated with PPD were age of the newborn (OR = 6.50, 95%CI: 1.17-19.91), marital relationship (OR = 4.15, 95%CI: 1.31-15.22), maternal educational level (OR = 5.10, 95%CI: 4.30-16.58), adverse life events (OR = 9.32, 95%CI: 1.33-35.32), and history of depression (OR = 5.24, 95%CI: 3.14-11.96).

Conclusion: Given the findings, there is an urgent need for policy initiatives to address the identified risk factors, such as improving access to education, strengthening supportive marital relationships, and providing comprehensive mental health services for pregnant women.

Published: March 2024

Objective: This study aimed to explore the dynamics of the relationship among smartphone addiction, quality of life, and personality characteristics in university students.
Method: This correlational and descriptive research was conducted to investigate the relationship between smartphone addiction, quality of life, and personality traits among university students. Using a nonprobability random sampling method, 496 university students were selected. Data collection involved the Student Information Form, Smartphone Addiction Scale, Symptom Checklist (SCL-90-R), Revised Eysenck Personality Questionnaire-Abridged Form (EPQR-A), and the WHO Quality of Life Scale-Short Form (WHOQOL-BREF). Statistical analysis was conducted with SPSS 25.0, utilizing Chi-square tests, independent sample t-tests, and Pearson's correlation analysis.
Results: Out of 496 students (average age of 20.52), 59.87% were identified as smartphone addicts based on the Smartphone Addiction Scale-Short Version. A notable difference was found by study year (P = 0.009) and socioeconomic status (P = 0.003). Participants with smartphone addiction registered higher SCL-90-r scores for conditions like Obsessive Compulsive Disorder, Interpersonal Sensitivity, and Psychoticism. The Eysenck Personality Inventory highlighted that the Psychoticism score was significantly higher in the group with smartphone addiction (P = 0.001). A negative correlation between smartphone addiction scores and general health (WHOQoL) was identified, whereas a positive correlation with SCL-90-R's Psychoticism dimension score was observed (P < 0.001).
Conclusion: Smartphone addiction is widespread among university student population. The study indicates that smartphone addiction not only impacts the individual's quality of life but also is associated with personality disorders, and these problems intensify with the severity of addiction. The findings underscore the need for interventions and educational programs to address smartphone addiction in this population.

Authors: Damián Núñez Edgar Froilan , Villanueva Lucia Mireya Soria , Mendoza Marco Antonio Tejada , Dorian Isla Alcoser Sandy , Palacios Garay Jessica Paola , Hernández-Vásquez Ronald
Published: March 2024

Objective: Traditionally, perfectionism has been regarded as a commendable trait in the realm of sports and exercise. However, recent research has uncovered a paradoxical aspect of perfectionism in these domains. This umbrella review seeks to offer a comprehensive overview of the intricate role that perfectionism plays in sport and exercise performance.
Method: As an umbrella review, we systematically explored three widely used scientific databases—PubMed, Scopus, and ISI—to identify relevant systematic reviewes and meta-analyses investigating the relationship between perfectionism and sports performance.
Results: After careful evaluation, eight studies met our inclusion criteria and were included in the study. These eight eligible studies comprised five systematic reviews and three systematic review and meta-analysis publications. These publications have explored the correlation between perfectionism and sports performance in teenager and adult populations, as well as professional and amateur athletes. Most of the original articles included in these studies had a cross-sectional design and some of them were longitudinal research. All reviewed articles reported a significant correlation between perfectionism and sports performance, regardless of gender and age. In general, the main consensus of these studies is a moderate to high positive correlation between perfectionistic strivings and sports performance, as well as a moderate to high negative correlation between perfectionistic concerns and sports performance.
Conclusion: In summary, perfectionism exhibits both positive and negative effects on athlete outcomes. Maladaptive perfectionism is linked to adverse consequences, while adaptive perfectionism can yield positive effects. Promisingly, psychological interventions such as mindfulness-based approaches and ACT-based interventions show potential in reducing perfectionism and enhancing athlete outcomes. Future research should delve deeper into the intricate relationship between perfectionism and athlete performance and continue to devise interventions that counteract the detrimental effects of perfectionistic tendencies.

The corrosion of materials poses a significant challenge in various industries, leading to substantial economic impacts. In this context, pyrimidine compounds emerge as promising, non-toxic, cost-effective, and versatile corrosion inhibitors. However, conventional methods for identifying such inhibitors are typically time-consuming, expensive, and labor-intensive. Addressing this challenge, our study leverages machine learning (ML) to predict pyrimidine compounds corrosion inhibition efficiency (CIE). Using a quantitative structure-property relationship (QSPR) model, we compared 14 linear and 12 non-linear ML algorithms to identify the most accurate predictor of CIE. The bagging regressor model demonstrated superior performance, achieving a root mean square error (RMSE) of 5.38, a mean square error (MSE) of 28.93, a mean absolute error (MAE) of 4.23, and a mean absolute percentage error (MAPE) of 0.05 in predicting the CIE values for pyrimidine compounds. This research marks a significant advancement in corrosion science, offering a novel and efficient ML-based approach as an alternative to traditional experimental methods. It shows that machine learning can quickly and accurately determine how well organic chemical inhibitors like pyrimidine stop material corrosion. This method gives the industry a new perspective and a workable solution to a problem that has existed for a long time.

Published: March 2024

Sleep paralysis, described as Kabus in Persian medicine (PM), is a state during sleep in which a person senses heaviness on the chest without the ability to speak or move. This study aims to review sleep paralysis from the viewpoint of Persian medicine. Five original reference books on PM were reviewed and data about the definition, etiology, and clinical features of sleep paralysis were extracted. Two main etiologies have been mentioned: evaporation of vapor to the brain and brain dystemperament due to cold reaching the brain; both of which cause weakness and dysfunction of the brain. PM recommends low-cost and available remedies for sleep paralysis such as dietary modification, oral and topical herbal medications, and manual interventions like “Fasd” (phlebotomy). Recent studies have shown the neuroprotective effect of these herbal drugs which can improve cognition and memory. Further studies are needed to evaluate the efficacy of the recommended remedies for sleep paralysis.

Sciatica commonly refers to radicular leg pain which is mainly caused by lumbar disc herniation (LDH) and affects the daily functional ability of many patients in the world. However, according to the side effects and short-term benefits of its treatments, new therapeutic agents such as natural products are needed. The aim of this study was to comprehensively review the effectiveness of plant-derived products for the treatment of sciatica. Electronic databases, including Medline (via PubMed), Scopus, and Web of Science, were searched from inception to 17 August 2023 for this comprehensive review. English language papers reporting preclinical and clinical evaluations of the effectiveness of herbal products, including medicinal plants, multi-component herbal preparations, and phytochemicals on sciatica, radicular pain, or LDH, were included. Studies on neuropathic pain due to reasons other than sciatica, radicular pain, or LDH were excluded. From a total of 5666 papers identified in the primary search, 16 (including 4 clinical and 12 preclinical studies) were finally included. Most of the plant-derived treatments mentioned in this review belonged to the polyphenol family or contained high concentrations of various polyphenols. From the results obtained, polyphenols relieved sciatica by reducing inflammation and oxidative stress, mainly through the inhibition of mitogen-activated protein kinases pathways. In conclusion, plant-derived medicines have the potential to improve the quality of life and functional ability of sciatica patients by relieving symptoms. However, further preclinical and clinical studies are suggested to prove the safety and efficacy of such herbal medicines for sciatica.

These enterprises are implementing measures to trace and track raw materials and components, ensuring compliance with sustainability standards and ethical sourcing practices. This transparency is crucial in identifying and mitigating environmental and social risks within the supply chain. However, it is important to note that there is still a lack of extensive research in the context of China regarding sustainable practices in global supply chains. While some studies and initiatives have been conducted, there is a need for more comprehensive research to understand the specific challenges and opportunities faced by Chinese enterprises in adopting and implementing sustainable practices throughout their supply chains. The objective of this study is investigating the research progress on issue related Sustainable Practices in Global Supply Chains of Chinese Enterprises. In doing so, systematic literature research was implemented on the supply chains of Chinese enterprises' foreign direct investment (FDI) to provides insights into the penetration and significance of sustainable concepts in this topic. This paper utilizes advanced data visualization techniques and an in-depth literature review to comprehensively summarize and review previous research extracted from the Web of Science database.  The study included 518 articles and analyzed them through RStudio and VOSviewer software. Research analysis reveals that most of the past research articles on this topic primarily come from China, followed by large economies such as the United States and the United Kingdom. However, when ranked by influence, the order is Canada, the UK, and the US. Around 2020, collaborations between countries mainly occurred in Asian nations. China, enterprises, and FDI are currently the most popular keywords. The importance of sustainability in the research on FDI in Chinese enterprises has been verified through data analysis and theoretical review. Key terms related to sustainability, such as "carbon dioxide emissions, economic growth, and energy consumption", are expected to play a vital role in future research. Current theoretical studies confirm that integrating environmental, social, and economic goals (ESG) into supply chain operations can implement a sustainable philosophy for the entire product lifecycle in Chinese OFDI enterprises. Disseminating sustainable management principles in supply chains among Chinese OFDI companies can contribute to ESG sustainability goals, while also enhancing the long-term profitability of the companies themselves.
Spectral Response of Two Hyperspectral Cameras for UXO Endmember Selection
Authors: Bajić Milan , Potočnik Božidar
Published: March 2024

There is currently no recommended procedure for acquiring endmembers in hyperspectral target detection when targets are larger than a single pixel. What is the best approach when multiple cameras are available for a dataset construction? This study examines the differences between hyperspectral cameras Specim IQ and Specim Imspector V9 that recorded the same surfaces under the same lighting conditions. A white balance card and a mortar mine are considered. As calibration procedures for cameras differ, raw data without processing are compared, and the same wavelength range is chosen. Clear differences are noticed between the spectra of the two cameras. Finally, guidelines for selecting statistically reliable endmembers and constructing an endmember dataset are provided based on the obtained results.
Russia pivot to (Southeast) Asia. Polityka Rosji wobec Azji Południowo-Wschodniej w XXI wieku
Authors: Pietrasiak Małgorzata
Published: March 2024

Tytuł książki nawiązuje do hasła, które pojawiło się w debacie politycznej na początku drugiej dekady XXI w. Hasło jest prowokacyjne bowiem z jednej strony parafrazuje amerykański powrót do Azji (US pivot to Asia), a z drugiej strony przypomina nie tylko o geograficznej ale i politycznej obecności Rosji w Azji. Dla Rosji, ze względu na jej bezpieczeństwo najważniejszym pozostaje region Azji Północno-Wschodniej, ale w drugiej dekadzie XXI wieku coraz aktywniej FR działała w regionie Azji Południowo-Wschodniej.  Państwa ASEAN zaczęły rozwijać się szybko i podjęły szereg działań sprzyjających ściślejszej integracji. Rosnące znaczenie Azji Południowo-Wschodniej skłoniło Rosję do wypracowania strategii wobec tego subregionu. Jest on elementem szerszej gry geopolitycznej Rosji i należy postrzegać go przez pryzmat budowania równowagi między najważniejszymi mocarstwami regionalnymi: USA, Chinami, Japonią i Indiami z jednej strony a poszukiwaniem własnego miejsca na tej „szachownicy”.  Najbardziej znaczące dziedziny współpracy z ASEAN to kwestie bezpieczeństwa i handel bronią, energetyka i surowce energetyczne. Pomimo deklaracji współpraca gospodarcza i handlowa rozwija się wolno. Przykładem ostatniej inicjatywy, która została zgłoszona przez prezydenta Władimira Putina jest Wielkie Partnerstwo Eurazjatyckie. Oceniam, że na tym etapie inicjatywa jest mało realna, zwłaszcza ze względu na ekonomiczne ograniczenia ze strony Rosji, choć działania dyplomatyczne trwają. Pewną niewiadomą pozostaje w tym wypadku czynnik chiński, bowiem Wielka Eurazja odwołuje się geograficznie do chińskiego projektu Pasa i Szlaku. Najważniejszym partnerem Rosji w regionie pozostaje Wietnam, a oprócz niego do grona większych partnerów handlowych należy Singapur, Indonezja, Tajlandia i Malezja.

Background: Lablab purpureus (L.) bean research in Uttar Pradesh has given less emphasis on improving quality traits preferred by farmers and focused mostly on developing varieties that are high yielding. Though, there are some released Lablab purpureus (L.) varieties farmers mostly prefer to grow their own landrace. Moreover, analysis of farmers’ perceptions and views on Lablab purpureus (L.) bean diseases and control methods utilized by farmers has been minimal. Farmers’ insights and understanding of crop diseases play an important role in sustainable disease management. Therefore, there is a need to assess farmers’ priority problems for Lablab purpureus (L.) bean production, their variety preference and their perception of the leaf spot disease. Methods: In our study, the landraces were assessed both in the field and in the greenhouse during 2021-22 with Alternaria doliconidium and Alternaria destruens isolates. Result: The highest level of resistance were found Under greenhouse evaluation in VRSEM-757, VRSEM-776, VRSEM-730 and VRSEM-739 to Alternaria doliconidium whereas genotypes found to be resistance under field evaluation were VRSEM-799, VRSEM-757 and VRSEM-776. Similarly, genotypes found to be resistance to Alternaria destruens were VRSEM- 757 and VRSEM- 702 under greenhouse evaluation whereas, genotypes VRSEM-776 found to be resistance during field evaluation.However, the resistance were moderate. Overall, resistance were highly heritable, suggesting that phenotypic selection can be exploited to improve leaf spot resistance in lablab bean varieties.
Henning Nølke’nin Önleyici Bağlamları Çerçevesinde Karşıtsal Sözcelerin Çok Sesli Çözümlemesi: Ayrık Tümce Örnekleri
Authors: PAMUKCU Gülden
Published: March 2024

Bir sözcenin çok sesli olarak yorumlanmasına olanak tanıyan bazı metinsel ya da dilsel unsurlar bulunmaktadır. Oswald Ducrot’ya göre olumsuzlama çok önemli birçok seslilik unsurudur ve karşıtsal, betimsel ve üstdilsel olmak üzere üçe ayrılır. Öncelikli olan karşıtsal olumsuzlamadır çünkü olumsuzluğun özü karşıtlıktır. İskandinav dilbilimci Henning Nølke olumsuz sözcelerin yorumlanmasında çok sesliliğe sebep olan bir takım dilsel bağlamlar ortaya atar. Bunları “önleyici bağlamlar” olarak tanımlar. Bu çalışmada dilbilimsel çok seslilik kuramı çerçevesinde sözcelerin çözümlenmesinde bağlamın yeri ve önemi gösterilmiş ve Henning Nølke’nin öne sürdüğü dilbilimsel çok sesliliği destekleyen dilsel bağlamlardan ayrık tümce örnekleri metinsel bağlamlarıyla desteklenerek uygulamalı olarak çözümlenmiştir. Olumsuzlama ile birleşen ayrık tümcelerin karşıtsal olduğu ve çok sesliliği destekleyen önleyici bağlamlar arasına girdikleri sonucuna varılmıştır.
