This study delves into the impact of personal traits on rural female entrepreneurship within family-owned enterprises. We investigate how rural female entrepreneurs strategically navigate their businesses, taking into account market conditions, technical aspects, financial considerations, operational challenges, organizational dynamics, and innovation factors. Employing a mixed-method approach, we collected quantitative data from 183 formal and informal rural female entrepreneurs using a semi-structured questionnaire available in both English and Arabic, utilizing snowball sampling. Through Exploratory Factor Analysis (EFA), we identified strategic objectives, and Confirmatory Factor Analysis (CFA) assessed the alignment of the proposed approach with the data sample. Additionally, we present six brief case studies based on interviews with female entrepreneurs to gain insights into how personal traits influence strategic entrepreneurial behaviour. Our findings highlight the significant influence of age and education on the strategic goals, motivation, and decision-making of rural female entrepreneurs. This research has broader implications for policymakers and stakeholders, offering insights into encouraging inclusive and sustainable female entrepreneurship in diverse rural contexts. By recognizing the relationship of personal attributes and institutional forces, this study contributes to our understanding of entrepreneurship in a dynamic and culturally rich environment, ultimately contributing to socioeconomic development in Oman and beyond.
Influence of psychological variables on divergent thinking in adolescents: A cross-sectional study
Authors: Sandhiya Veerasamy , Bhuvaneswari Mohanraj
Published: October 2023

Divergent thinking (DT) is a thought process wherein many original ideas are conceptualized and unique suggestions are proffered to identify the best possible solution to a problem; it is an important component of creativity. The present study endeavors to examine the level of DT in school students and the primary factors influencing DT with the help of assessment tests such as Standard Progressive Matrices (SPM), the Emotional Intelligence Scale (EIS test), and Sharma’s Divergent Production Abilities Test (DPA). A cross-sectional study is done using quantitative methodology and probability sampling techniques. The participants of the study are [n = 192 (boys = 106, girls = 86)] school students in the age range of 11–14 years, and the study area is Tiruppur district in Tamil Nadu. Results indicate that DT and EI are negatively correlated with each other, and there is no relationship between DT and intelligence quotient (IQ). Gender differences in DT are identified, with males scoring higher than females on assessment tests. There is no significant difference between the influences of demographic factors like geographical area, economic status, age, birth order, and hand preference on DT. The study’s major conclusion about education is that students at CBSE schools do better than those at private and government-run schools. The performance of government school students is rather poor when compared to CBSE and private schools. This indicates that government school students require proper training, timely assistance, and innovative teaching methods, which lead to the enhancement of DT and creativity.

Authors: Abbas Abdullah Ali , Salman Suzan Ali , Abdul Wahid Maha Hatem
Published: October 2023

Background: The bone morphogenetic protein belongs to transforming growth factor beta (TGF-β), and it is regarded as one of the biological factors that play major roles in the process of osteogenesis. Objective: To measure the effect of recombinant human bone morphogenetic protein-2 with an absorbable collagen sponge carrier (rhBMP-2/ACS) on secondary implant stability and study the relation of other parameters like implant receipt jaws, implant diameter, and implant length with implant stability. Methods: Ten participants were enrolled in the study after a selective diagnosis. Forty-seven implants were classified into two groups: the study group included twenty-three dental implants with an additive of rhBMP-2/ACS, and the control group included twenty-four dental implants without an additive. Each patient received at least two implants on each ipsilateral side. The primary implant stability was measured at the surgical phase, and the secondary implant stability was recorded after 16–24 weeks by using the Resonance Frequency Analysis device. Results: There was a weak but not significant correlation between implant dimensions and stability, except in the control group. Concerning the ISQ relation to the jaw, the mandible showed a significant increase in primary stability for the study group compared to that in the control group, but no statistical relation was recorded. Conclusion: The mandible had higher ISO values for primary stability than the maxilla in both groups, with a non-significant connection. The maxilla in both groups had improved secondary stability, whereas the mandible had decreased. (clinicaltrials.gov-NCT05719181).

The intersection of IoT technology and machine learning has ushered in a new era of precision agriculture, offering innovative solutions to the pressing challenges of food security and environmental sustainability. This paper presents a comprehensive study on the integration of IoT sensors and machine learning techniques for crop yield prediction, with a focus on the ten most consumed crops worldwide. Leveraging a wealth of historical data encompassing environmental variables, pest conditions, and crop-specific attributes collected by IoT sensors, we develop and rigorously evaluate a predictive model employing gradient-boosting regressors. Our findings reveal that the proposed model excels in capturing the intricate relationships between IoT sensor data and crop yield predictions, outperforming established ML regressors in a series of comprehensive experimental comparisons. These results underscore the potential of data-driven decision-making in agriculture, equipping farmers and policymakers with tools to optimize resource allocation, risk management, and sustainable farming practices. In the context of a growing global population and changing climate, the insights from this research hold significant promise for transforming precision agriculture and enhancing global food production.

hand the idea of interval-valued neutrosophic soft sets (IVNSSs) is a new generalization of the neutrosophic soft sets to the neutrosophic sets when the authors combine the critical features of IVNS and soft sets (SSs) in one model. Accordingly, this model worked to provide decision-makers with more flexibility in the process of interpreting uncertain information. From a scientific point of view, the process of evaluating this highperformance IVNSS disappears. Therefore, in this paper, we initiated a new approach known as possibility interval-valued neutrosophic soft sets (PIVNSSs) as a new development in a fuzzy soft computing environment. We investigate some fundamental operations on PIVNSSs along with their basic properties. Also, we investigate AND and OR operations between two PIVNSSs as well as several numerical examples to clarify the above fundamental operations. Finally, we have given similarity measure (SM) between two PIVNSSs to construct a new algorithm that is used to demonstrate the effectiveness of the method in handling some real-life applications.

Published: October 2023

The article’s aim is to analyze the distance learning peculiarities in the professional training of the specialty “Information, library, and archive management” based on the European experience. Methodology. For the revelation of the problematic the systematic method, comparative analysis, abstraction, and dialectical method were used. The results evaluated the experience of European universities in the implementation of relevant educational programs, namely the British, French, Spanish practices were analyzed. Since 2007 the European Union has been funding research to explore the best models for organizing distance education. Many universities have integrated library, information, and archival specialties, inspired by the British experience. Training in these fields focuses on equipping students with competencies that are applicable across these professions. While the UK's digitalization and information infrastructure are advanced, other countries can still benefit from adopting their experience, formalized in a national standard. France and Spain have also given significant attention to the issue of distance learning. Spain, for instance, has been diligently preparing for the introduction of distance learning since 2010. The practical significance and novelty of the research lies in its potential to offer valuable insights into the best practices and approaches adopted by EU in organizing distance learning for these professions. Other nations and regions can learn from these experiences. In conclusions it is shown, that across all European Union countries, there has been a common emphasis on ensuring both teachers and students possess digital competence, a critical element in organizing training for information, archiving, and librarianship.

Published: October 2023

Purpose. Non-syndromic hereditary ocular diseases can lead to severe functional limitations of vision at all ages. Therefore, molecular genetic research into the causes of hereditary ocular diseases is of paramount importance. Due to the increasingly optimised pathophysiologically adapted treatments and gene therapy options, a rapid determination of the genetic cause of hereditary ocular diseases is neces- sary, also to increase the chances of treatment at early stages of the disease. In this context, the authors retrospectively analysed the database of the “rare diseases” consultation hour of the PraxisKlinik Augenärzte Halle, which has been in existence since 2016, for patients with a suspected hereditary ophthalmological disease after molecular genetic diagnostics, counselling and therapy options. Material and Methods. 367 index patients were treated dur- ing the period under consideration. In 221 (60.2 %) of them, the molecular genetic cause of the underlying disease could be found. In addition to a large group of patients with cor- neal dystrophies (304 patients, detection rate 61.2 %), we treated 23 index patients with hereditary retinal diseases (detection rate 69.6 %), 28 index patients with complex mal- formations (detection rate 50 %) and 15 index patients with optic atrophies (detection rate 33.4 %). In addition to the ophthalmological-clinical examination and diagnostics, ge- nealogical analysis and molecular genetic testing were always performed. Results. On the basis of 3 case studies with a molecularly ge- netically proven hereditary retinal disease (X-linked recessive inherited juvenile retinoschisis, hemizygous missense muta- tion in the RS1 gene; enhanced S-Cone syndrome, compound heterozygous mutation in the RS2E3 gene; oculocutaneous albinism, homozygous mutation in the TYR gene), the inher- itance, the clinical picture, the course and the therapeutic and rehabilitative options were explained. Conclusion. Ophthalmogenetic counselling and diagnostics in cases of suspected hereditary eye diseases are crucial for a prompt and a suﬃcient possible therapy and optical reha- bilitation in aﬀected families. Thorough history analysis and diagnostics can optimise the detection rate and provide rapid and suﬃcient patient care.

Netzhautriss – optometrisches Management
Authors: Fröhlich Brian
Published: October 2023

Purpose. This case report describes the optometric manage- ment of a peripheral retinal tear that was discovered during an optometric eye examination. It is intended to sensitize optometrists and ophthalmic opticians to the topic of retinal tears and retinal detachment. Material and Methods. During an optometric eye examina- tion, the fundus was examined using an ultra-wideﬁeld laser scanning ophthalmoscope. A retinal tear was detected in the fundus periphery. Results. After the comprehensive optometric examination, the patient was informed about the ﬁnding of a peripheral retinal tear and its consequences and referred to an eye clinic. At the eye clinic, the diagnosis was conﬁrmed. Treatment consisted of preventive laser retinopexy to reduce the risk of subsequent tear extension and retinal detachment. Conclusion. The retinal tear presented in this case report was detected as an incidental ﬁnding. The patient was referred to an eye clinic for specialist diagnosis and preventive treat- ment. The case shows that a comprehensive optometric eye examination not only enables the management of relevant refractive errors, but can also make a contribution in terms of preventive health care. Optometric involvement in eye care has the potential to lead to earlier diagnosis, allowing treatment strategies to be implemented at an earlier stage. Together, earlier diagnosis and earlier intervention can lead to better long-term health outcomes. Keywords Fundus examination, fundus periphery, retinal tear, retinal detachment, retinopexy
Keratokonus, Sklerallinsen und Glaukom-Drainage-Implantat
Authors: Pöltner Gustav
Published: October 2023

Purpose. This case report describes scleral lens ﬁtting for advanced keratoconus in combination with additional glaucoma surgery. Material and Methods. The implantation of a drainage implant was followed by the bilateral ﬁtting of scleral lenses. For contact lens ﬁtting, it was essential to work with a scleral lens system that allows individual zone size and edge clearance in the scleral alignment zone to prevent provocation of the postoperative area. Results. Due to the individualized design of the scleral lenses, the patient was able to wear scleral lenses again postopera- tively with successful implantation of a drainage implant. A prerequisite for this was also that the surgeon considered the necessity of a later postoperative ﬁtting with scleral lenses when choosing the surgical method. Conclusion. Scleral lenses can also be successfully ﬁtted in cases of complex corneal shapes and surgical procedures on the eye. This requires not only a great clinical experience in ﬁt- ting such contact lenses, but also an individual manufacturing of the contact lenses based on the contact lens parameters speciﬁed by the contact lens specialist. Keywords drainage implant, scleral lens with peripheral torus, zone size, x-value

Approximately 36% students marked family history for headache/migraine. Breakfast skipping frequency among undergraduate students was 84% out of which 71% students were experiencing fatigue and lethargy (p-value = 0.039). Almost 75% students experienced hypoglycemia due to breakfast skipping and 85% students experienced headache/migraine due to hypoglycemia (p-value = 0.019). Conclusions: There is a significant link found between headache/migraine, hypoglycemia and breakfast skipping habit among undergraduate university students.
SWAN: SOCIAL WORK AT ALL LEVELS. DESIGNING A TOOL FOR MULTILEVEL INTERVENTION
Authors: Verharen Lisbeth , Pelt Mariël  Van , Menheere Ilse , Moorman Nicole , Sleegers Richard
Published: October 2023

Social workers focus on changes and improvements in people’s social functioning and the social quality of society. To do so, they intervene at different levels: individuals and households (micro), groups, neighbourhoods and communities (meso), and organisations and policies (macro). Opportunities for multilevel interventions are under-utilized in the Netherlands, as social workers mainly focus on the micro level. Researchers from HAN and Movisie were asked to develop a tool which supports decision making on various intervention levels. In a design-oriented study, together with social workers, they developed SWAN (Social Work at All Levels): a conversational guide in the form of a card set, based on the theory of social quality and the decisive professional model. This tool is designed to help social workers look more broadly at a practice situation, recognise points of intervention at different levels, choose between interventions at these levels, and to justify their choices. Although social workers can use SWAN to identify intervention opportunities at all levels, it is not yet clear whether this actually leads to more interventions at meso and macro level.

A aplicação transdérmica de princípios ativos terapêuticos proporciona muitas vantagens em relação a outras vias de administração, como o aumento da eficácia dos tratamentos e poucos efeitos colaterais. Desta forma, tem-se buscado maneiras de ampliar a permeação destas substâncias na pele, destacando-se a técnica de fonoforese, um recurso frequentemente utilizado na pratica clínica. Cabe ressaltar que esta técnica ainda apresenta efetividade desconhecida quando associado a algumas substâncias tópicas, como por exemplo, o ácido ascórbico (AA). Neste sentido o presente estudo buscou comparar o efeito da liberação, retenção e permeação do AA 5% associada ao ultrassom (US) contínuo in vitro utilizando acetato de celulose e pele suína. Os ensaios de liberação foram realizados nos tempos de 5, 10, 15 e 20 minutos, sendo que o US se mostrou efetivo em termos de liberação nos três primeiros tempos. A parte analítica de retenção e permeação, foi avaliada nos tempos de 20 minutos, uma hora e duas horas. Observou-se que houve aumento da retenção na epiderme do AA nos tempos de uma hora e duas horas, sendo de 123,46% e 206,71%, respectivamente; nas demais análises não foi possível verificar diferença entre os grupos comparados.

Nos dias de hoje, o mundo digital desempenha um papel fundamental em nossas vidas, desde o trabalho e a educação até o entretenimento e a comunicação. No entanto, muitas vezes esquecemos que a acessibilidade tecnológica é um direito básico que deve ser estendido a todos, independentemente de suas habilidades físicas ou cognitivas. Os desafios em torno da acessibilidade tecnológica são numerosos e complexos. Para aqueles com deficiências visuais, a falta de interfaces de usuário amigáveis e a ausência de descrições adequadas de imagens são obstáculos significativos. Para pessoas com deficiências motoras, dispositivos de entrada não adaptados podem dificultar o uso de tecnologias. Além disso, indivíduos com dificuldades de aprendizado podem enfrentar barreiras significativas na compreensão de conteúdo digital.

Hai trình tự DNA của gen (matK và rbcL) được sử dụng để phân tích di truyền 5 mẫu lá được lấy từ 5 cây khác nhau (3 mẫu ở Trà Vinh và 2 mẫu ở An Giang). Kết quả, trình tự của cả 2 vùng gen của cả 5 mẫu đều được khuếch đại thành công 100%, với biểu hiện băng khoảng 930 bp ở gen matK và 1.400 bp ở gen rbcL. Kết quả phân tích mối quan hệ di truyền giữa các mẫu nghiên cứu dựa trên trình tự DNA (nucleotide, polypetide) của cả 2 vùng gen trên đều cho thấy có sự tương đồng cao giữa các mẫu nghiên cứu, cả 5 mẫu nghiên cứu đều thuộc cùng một nhóm với giá trị bootstrap 89% dựa vào tình tự của matK và 100% dựa vào trình tự rbcL. Trình tự DNA của cả 2 vùng gen matK và rbcL đều chỉ ra 5 mẫu nghiên cứu thuộc cùng nhóm loài Nưa (Tacca leontopeloides (L.) Kuntze) đã được công bố trên thế giới với giá trị bootstrap 100% cho cả 2 vùng gen. Kết quả nghiên cứu thu được đã khẳng định rằng, cây Nưa đang được trồng ở Trà Cú (Trà Vinh) có tên khoa học là (Tacca leontopeloides (L.) Kuntze); và có sai khác không đáng kể so chúng ở An Giang cũng như trên thế giới cấp độ phân tử.
