On pointwise quasi bi-slant submanifolds
Authors: Akyol Mehmet , Beyendi Selahattin , Fatima Tanveer , Ali Akram
Published: April 2023

In this paper, we introduce a new class of submanifolds which are called
pointwise quasi bi-slant submanifolds in almost Hermitian manifolds which
extends quasi bi-slant, bi-slant, hemi-slant, semi-slant and slant
submanifolds in a very natural way. Several basic results in this respect
are proved in this paper. Moreover, we obtain some conditions of the
distributions which is involved in the definition of the new submanifolds.
We also get some results for totally geodesic and mixed totally geodesic
conditions for pointwise quasi bi-slant submanifolds. Finally, we illustrate
some examples in order to guarantee the new kind of submanifolds.
Riemannian concircular structure manifolds
Authors: Chaubey Sudhakar , Suh Young
Published: April 2023

In this manuscript, we give the definition of Riemannian concircular
structure manifolds. Some basic properties and integrability condition of
such manifolds are established. It is proved that a Riemannian concircular
structure manifold is semisymmetric if and only if it is concircularly flat.
We also prove that the Riemannian metric of a semisymmetric Riemannian
concircular structure manifold is a generalized soliton. In this sequel, we
show that a conformally flat Riemannian concircular structure manifold is a
quasi-Einstein manifold and its scalar curvature satisfies the partial
differential equation ?r = ?2r/?t2 + ?(n?1)?r/?t. To validate the
existence of Riemannian concircular structure manifolds, we present some
non-trivial examples. In this series, we show that a quasi-Einstein manifold
with a divergence free concircular curvature tensor is a Riemannian
concircular structure manifold.

Little is known about if and how nevi and pigmentation are associated with melanoma-specific mortality. However, increased melanoma awareness in people with lighter pigmentation and many nevi may result in earlier diagnosis of thinner less-lethal tumors. The aim of this study was to investigate associations between nevus count (asymmetrical > 5 mm and small symmetrical), pigmentary characteristics (hair colour, eye colour, skin colour, freckling, pigmentary score), and melanoma-specific mortality in subjects with melanomas > 1 mm. Data from the Norwegian Women and Cancer cohort, established in 1991, with complete follow-up of melanoma patients until 2018 through the Cancer Registry of Norway, were used to estimate hazard ratios with 95% confidence intervals for the associations between nevus count, pigmentary characteristics, and melanoma-specific mortality, stratified by tumor thickness using Cox regression. Estimated hazard ratios consistently indicated a higher risk of melanoma death for those with darker vs lighter pigmentary characteristics in patients with tumors > 1.0–2.0 mm and > 2.0 mm thick (e.g. pigmentary score hazard ratio 1.25, 95% confidence interval (0.74–2.13)). Among women with melanomas > 1.0 mm thick, lighter pigmentation and asymmetrical nevi may be associated with lower melanoma-specific mortality, suggesting that factors that increase the risk of melanoma may also be associated with decreased risk of death from melanoma.

Authors: Menakaya Ifeoma Nkiruka , Menakaya Nnamdi , Abah Aderonke Adebowun , Agboghoroma Gloria Okeoghenemaro
Published: April 2023

Background: COVID-19 remains a major public health threat globally and dental practitioners are particularly at risk due to the proximity of care givers to the patient and the generation of aerosols during many dental treatment procedures. Dental practitioners are therefore required to strictly observe standard universal precautions in their clinical practice.

Objectives: To determine the safety precaution and infection control practices among dental practitioners in Nigeria during the COVID-19 Pandemic.

Methods: A cross-sectional self-administered pre-tested questionnaire based survey of consenting dental practitioners from different geopolitical zones in Nigeria was employed for the study. Study participants were recruited by non-random convenience sampling. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20.

Results: A total of 105 out of 142 respondents completed and returned the survey questionnaire giving a response rate of 74%. About 24-55% of study respondents performed aerosol/splatter/droplet generating procedures. Hand hygiene and donning of face mask were the most common safety practices while the use of face shield and N95 facemask were common infection control practices. Over 60% of respondents practiced triaging of patients, pre-procedural mouth rinse and donning of disposable surgical gowns. Almost half of the respondents practiced decontamination of the clinic work environment and over 70% of respondents used N95 masks.

Conclusion: Aerosol generating procedures were not uncommon dental practices in Nigeria during COVID-19 pandemic. However, use of N95 mask was relatively high and there was a reasonable level of practice of basic standard COVID-19 safety measures and infection prevention and control guidelines.

Authors: Arakji Hani , Osman Essam , Aboelsaad Nayer , Shokry Mohamed
Published: April 2023

Introduction: Maxillary sinus pneumatization and alveolar ridge resorption following the extraction of posterior teeth make the installation of dental implants in the maxillary posterior region challenging. The direct sinus lift procedure proved to be a viable treatment option for such conditions. Aim of the study: to evaluate the mineralized plasmatic matrix/xenograft mixture in sinus elevation surgery.
Materials and Methods: Eighteen patients were selected and randomly allocated into two groups; study group received a mineralized plasmatic matrix/xenograft mixture, while the control group received xenograft alone following sinus lifting.
Results: The early wound healing index score showed a non-significant difference between both groups. Also, bone height was evaluated at the 6-month follow-up period, and there was a non-statistically significant difference. Core biopsies were taken for histological examination by H&E from both groups, revealing the presence of a more mature bone matrix in relation to the test group.
Conclusion: The addition of mineralized plasmatic matrix to xenograft can speed up bone formation, thus reducing treatment duration.

Published: April 2023

The COVID-19 pandemic affects the entire world and took about 4.25% of people’s life compared with SARS-CoV-2. In this challenging situation about 25,000 frontline healthcare workers are affected by COVID-19 while providing support for the infected people. Hence, frontline workers are highly affected by the COVID-19 virus due to the absence of appropriate drugs or vaccines. The increase in the spread of the virus leads to a shortage of healthcare workers in different countries. In this scenario, to protect the frontline workers from the COVID-19 virus robots integrated with Artificial Intelligence are employed for pandemic diseases. This paper evaluated the contribution of robotics to the COVID-19 pandemic which comprises Artificial Intelligence. Initially, this paper presented the existing robotics model employed for the COVID-19 pandemics are examined. Through the analysis, the Simultaneous Fast Filtering Localization and Mapping (SFFLAM) model is developed for the hospital environment to promote frontline worker safety in the COVID-19 pandemic. The proposed SFFLAM model uses the extended Kalman filtering integrated with the sectorial error probability (SEP) for robot localization. The examination of robots expressed that through the integration of artificial intelligence robots are employed for the medical, UV-disinfectant, social, COBOTS, and drones. The examination expresses that the proposed SFFLAM model exhibits improved robotics performance for localization and processing. The application of robots with artificial intelligence increases the performance of the overall robot in the hospital during pandemic situations.

Authors: Ogutu Hellen , El Archi Youssef , Dénes Dávid Lóránt
Published: April 2023

Research background: Sustainability in organizations is a business approach to creating long-term value by taking into consideration how a given organization operates in the ecological, social, and economic environments. The organizational practices that eventually lead to sustainable development are referred to as sustainable organization management.
Purpose of the article: The purpose of this paper is to examine the current trends in sustainable organization management over the time period of 2015?2022, highlight the emerging themes in this study area, and provide guidance for further research in the field.
Methods: This paper uses bibliometric meta-data analysis to present an analysis of current trends in sustainable organizational management. An in-depth analysis of a sample result of 619 papers from the Web of Science core collection was conducted with the use of biblioshiny, the R-Programming Language package, and the VoS Viewer software. A global representation of concepts was created using the relational directory network visualization technique based on VoS Viewer software. Keyword cooccurrence relationships were determined; relational techniques were used to visualize bibliographic coupling density to identify thematic areas with little research; and overlay visualization bibliometric techniques were used to identify new and old research themes.
Findings & value added: Emerging themes are modeling, tourism, and perceptions. Motor theme areas in the field of study include performance, impact, and management. The paper concludes that the study area of organizational sustainability management is still in its early stages and has great research potential, such as Africa as a study area, despite the fact that there have been few or no research findings. Future research should examine the role of technology and innovation in promoting sustainable practices within organizations and clarify how well an organization can survive global competition.
Talent development of Selma Lagerlöf, an outstanding Swedish writer
Authors: Ruban Larysa
Published: April 2023

The article carries out a biographical study of the childhood and youth of Selma Lagerlöf, with the purpose of determining the conditions that influenced the development of her genius abilities to create fairy tales. Research methods: study, analysis and generalization of special scientific literature in order to identify the state of the researched problem. The biographical study of S. Lagerlöf’s childhood and youth combines environmental and personal approaches. Thus, S. Lagerlöf’s grandmother narratives about hereditary estate were the main factors that influenced the development of imagination and excellent literary abilities of S. Lagerlöf. The girl was very pleased to listen to grandmother’s stories, which were full of legends and secrets. When at the age of three, S. Lagerlöf suffered from paralysis, those stories were exactly the only consolation for her because in these narratives the girl drew strength and inspiration. It is likely that thanks to these legends and stories about the family nest and Sweden as a whole, S. Lagerlöf began to fantasize and create her own stories, which were permeated with love to her native land. It is possible that the grandmother and her stories instilled in the girl faith in miracles, goodness, and fairy tales. After all, regardless of the serious illness, S. Lagerlöf did not lose hope for the best, wisdom, optimism and continued to write her brilliant works, imbued with devotion to her native home. The writer depicted the beauty of the home more than once in her works. S. Lagerlöf created in her works a world full of romance, fabulous adventures, and idleness. The article highlights the features inherent in S. Lagerlöf’s fairy tales. First, the events in the writer’s works happen in places dear to her heart – the city, the country. Secondly, S. Lagerlöf resorted to romantic literary techniques. Thirdly, the writer used a well-known literary device in her fairy tales – personification, that is, animals, birds, insects acquire human features, they behave like people. It was concluded that S. Lagerlöf was a romantic, dreamy person who loved her homeland immensely. The problem outlined in the article is relevant and needs further processing in order for it to be thoroughly completed.

Published: April 2023

ABSTRACTIntroduction: Calcite (CaCO3) is typically used in commercial toothpaste with particle size ranges from 1-12 μm. In the latest study, calcite was synthesized by using Ca(OH)2 precursor from natural resources However, the resulting particle size does not match the size of the toothpaste filler. This study aims to prepare micro-calcite via fine-bubble assisted carbonation as toothpaste material. Methods: The calcite powder was prepared from Ca(OH)2 analytical grade powder utilizing the fine-bubble carbonation process with the Ca(OH)2 concentration and initial pH variation. The study was started by making a Ca(OH)2 suspension with a concentration of 0.25, 0.5, 0.75, 1 and 1.25 M using 2.000 ml methanol as a solvent. 0.5 M NaH2PO4 solutions were utilized to adjust the initial pH of 0.5 M Ca(OH)2 suspension into 8, 9, and 10. The suspensions were aerated using CO2 fine-bubble for two hours to produce CaCO3 samples. All precipitated CaCO3 particles were characterized by PSA, Zeta-Potential, and FTIR measurements. Results: The calcite phase was identified from the FTIR transmittance. Aragonite or vaterite phase was not observed in the samples. PSA result shows the size of CaCO3 particles from samples 0.25 M to 1.25 M are as follows 3.03, 3.23, 2.79, 3.70, 0.99 μm respectively. Meanwhile, the particle sizes of CaCO3 in samples with a pH of 8, 9 and 10 are 3.00, 2.03 and 2.50 μm respectively. The zeta potential shows the value ranges from -23.2 mV to -11.9 mV, indicating fair dispersion ability. Conclusion: The fine bubble assisted carbonation method in this study helps in producing calcite in micron size that could be used as alternative fillers for toothpaste.Keywords: calcite, fine-bubble, carbonation, particle size, toothpaste

Para el diseño y operación de cualquier servicio público, un elemento básico es determinar el número de personas a quienes se les prestará el servicio, no importando si es agua potable, drenajes, transporte o electricidad. Sin embargo, cuando los conglomerados urbanos son grandes o tienen ciudades dormitorio, la estimación de la población a servir se vuelve compleja, especialmente porque los censos poblacionales normalmente, solo consideran la población residente en un territorio. Así un distrito comercial o financiero, pueden tener una población residente relativamente pequeña, pero una población flotante considerable que, aunque solo trabaje, estudie o visite la zona, requiere los servicios básicos (agua, drenajes, etc.). Las mediciones de tráfico, dan un valor global de cuántas personas ingresan a un municipio o territorio, pero difícilmente determinan como se distribuyen en las zonas urbanas. El modelo propuesto, aprovecha las ventajas de los Sistemas de Información Geográfica (SIG), para ubicar la demanda, calculando un estimado de la población a servir, en función de los metros cuadrados construidos y tipo de uso. Esto permite no sólo determinar la población residente y flotante de una región, sino también, sectorizar y delimitar áreas específicas, para obtener los datos de población a servir en un sector, definiendo volúmenes de agua, redes, plantas potabilizadoras, tamaño de drenajes y descargas sanitarias, así como dimensionar plantas de tratamiento de aguas residuales (PTAR) o necesidades de transporte y servicio eléctrico. El modelo se aplicó en la zona urbana del Municipio de Guatemala, Guatemala, ubicado en América Central, obteniéndose la población residente y flotante por cada una de las zonas. El modelo permite definir la población flotante, estimarla a futuro en base a las proyecciones de área construida y ajustarlo conforme ocurran los cambios.

Objective: To investigate the fear of re-injury and its effect on returning to pre-injury sports activity level among patients who underwent anterior cruciate ligament (ACL) reconstruction.
Methods: A cross-sectional study was conducted among patients who underwent ACL reconstruction in King Fahad Hofuf Hospital, Eastern province, AlAhsa, Saudi Arabia in the last 5 years with a sample size of 385 patients. The questionnaire included the Arabic version of the return to sport (RTS) after ACL scale to assess patients' readiness for RTS without the fear of ACL injury, and Godin Leisure-Time Exercise Questionnaire to determine the level of exercise following surgery.
Results: A total of 204 patients eligible for the study were included with a mean age of 29.9 ± 14.5 years. Exactly 199 (97.5%) patients were males and 185 (90.7%) were football players. Among patients, 62.5% felt relaxed about playing sports and confident about the ability to perform well at sport (60.3%). However, only 46.4% of patients had thought of being likely to re-injury of knee by participating in sports again. Post-surgery, 89.2% were highly active. Young-aged patients and students showed statistically significant (p = 0.004) scores to return to pre-injury sport activity.
Conclusion: Less than half of the ACL reconstruction patients experienced fear of re-injury. Therefore, optimizing the surgical technique along with post-operative close follow up of the patient's psychological and physical status affect the patient's performance and activity level after surgery.

A escrita está na fonte de todo progresso humano. Há cerca de vinte mil anos o homem exprime o seu pensamento através de meios gráficos e há cerca seis mil anos conhece as formas de escrita. Desde então a palavra escrita passou por evoluções, tanto em sua forma quanto em seus suportes, formas de organização, equipamentos, dispositivos, rotinas, serviços etc. Nessa perspectiva, pode-se perceber que houve rupturas resultantes dos usos de novas modalidades de composição, de difusão e de apropriação do texto escrito. Dessa forma, podemos refletir a respeito das relações entre escritores e textos, leitores e textos e escritores e leitores, e também sobre como estas relações se transformaram através dos tempos, na medida em que os suportes textuais foram se alterando.

Published: April 2023

O objetivo deste estudo é compreender e discutir a violência doméstica contra homens em relacionamentos heterossexuais. Visou investigar como essas relações de violência ocorrem e o que as mantém. Método: O estudo partiu de revisões bibliográficas, apurando-se dados de artigos, livros e revistas da área. Além disso, realizou-se uma pesquisa de campo com sujeito voluntário único vítima de violência doméstica. Para a análise e compreensão dos dados utilizou-se como abordagem central a Análise do Comportamento. Resultados: A violência doméstica contra homens é uma realidade existente, mas pouco explorada na contemporaneidade. As cobranças sociais em torno da autonomia do homem, os poucos trabalhos de prevenção na área e a falta de preparo de profissionais para acolher o sofrimento masculino, dificultam a denúncia dos parceiros. O trabalho também revelou que a violência psicológica é a mais empreendida pelo público feminino. Conclusão: A violência psicológica é tão prejudicial quanto à violência física. Os comportamentos não assertivos observados no participante foram destacados como variáveis reforçadoras para a manutenção das agressões. Além disso, observou-se como as regras (casamento é para vida toda) exerce um controle forte para a manutenção da relação, a presença do reforço positivo (amor) que ainda existe na relação e a probabilidade de uma punição negativa (medo de nunca mais verem os filhos) como fatores que favorecem a manutenção da relação mesmo esta tendo conteúdos de agressão.

Published: April 2023

Efforts to reduce the dependency on fossil-based fuels have intensely been researched by scientists recently. Therefore, in internal combustion engines, the usability of various alternative fuels is still being evaluated. The present study experimentally focused on the illumination of the combined impacts of nanoparticle additives and hydrogen fuel on the performance and emission characteristics of a compression ignition engine. For this purpose, diesel fuel and combinations of diesel fuel, terebinth oil biodiesel, titanium dioxides nanoparticle, and hydrogen were utilized. Reduced engine performance caused by biodiesel was compensated with the use of nanoparticles. Further improvement was also observed with hydrogen addition. Emission results showed that carbon monoxide (CO) emission values can be reduced with biodiesel, nanoparticle additive, and hydrogen since they all have positive effects to enhance combustion quality and avoid incomplete combustion. On the other hand, oxides of nitrogen (NOx) emission was increased due to a rise in cylinder temperature with the use of biodiesel, nanoparticle, and hydrogen.

Authors: Fachri Zoel , Rouhillah  , Alwathani Muharrir
Published: April 2023

Soybeans are one of the main ingredients for making tempeh. Most of the tempeh production businesses still use the traditional system of washing soybeans. Washing soybeans is still done manually using a washing drum filled with water and stirred by hand, thus draining the workforce. In the process of washing soybeans, there is still direct contact with parts of the human body, resulting in unhygienic soybeans. From these problems, the solution is to make a machine that can wash soybeans in tempeh production which aims to facilitate washing soybeans and produce clean and hygienic soybeans. The soybean washing machine process uses a screw conveyor system with an AC motor 1 phase 1 HP 1420 Rpm as a driving force and a DC 12 V 25 W water pump to drain water into the watering canal. The machine can wash 5 kg of soybeans for 10 seconds, and produces a motor rotation of 271.2 Rpm, voltage 229 V, current 2.58 A to produce clean and hygienic soybeans.

Published: April 2023

Peptides are a re-emerged strategy to fight a plethora of diseases and their utility has been expanded to new areas. Now sequence-based peptide design opens up new possibilities to develop peptidic molecular entities. However, its methodological limitations (e.g., its inefficiency in designing large peptides and that do not allow the analysis of post-traductional modification) limit their applicability domain. In contrast, ligand-based molecular design approaches have demonstrated their extensive applicability domain, although the peptide design-based in this method continues been not exploited. The main limitation has been the complex molecular structure of peptides, which has not been studied using classical fingerprints tuned for small organic compounds. Towards this end, MAP4 is a recently developed universal fingerprint that allows quantifying the sequence/structure diversity of natural products or peptides. As part of the peptide design, there is a current trend to develop predictive models which are founded on the available structure-activity data available. Before developing such models, it is essential to characterize in detail the structure-activity relationship and identify if any activity cliffs: subtle structural modifications that have a large and unexpected effect on the biological activity. In this study, we map the structure-activity landscape of an exemplary dataset with 165 peptides (anti-methicillin-resistant Staphylococcus aureus peptides) using a similarity metric based on MAP4 fingerprint. Specifically, we characterized the activity landscape of this data set, and we identified key amino acids (AAs) and structural motifs that play a key role in the activity of the anti-methicillin-resistant Staphylococcus aureus peptides. To the best of our knowledge, this is the first chemoinformatics approach to systematically explore the activity landscape of peptides emphasizing the quantification of the structural similarity. The approach is general and can be extended to analyze the presence of activity cliffs in any set of peptides. Identifying activity cliffs has practical implications during the development of predictive models.

Published: April 2023

In this paper we report a catalytic method to transfer formal equivalents of HF from fluoroalkanes to an alkyne. The method leads to a simple and sustainable approach to generate difluoroalkanes and tolerates numerous sensitive functional groups including halogen, protected amine, ester and thiophene substituents. BF3-OEt2 catalyses this new catalytic transformation. Mechanistic studies (DFT, probe experiments) suggest the catalyst is intimately involved in both the defluorination and fluorination steps required for HF transfer, with BF3 acting as a Lewis acid and OEt2 a weak Lewis base that mediates proton transfer. Fluoroalkenes are demonstrated as competent intermediates and their conversion to difluoroalkanes was found to be reversible. These results establish the first true HF shuttle process (i.e. bidirectional) and represent a potentially powerful method for recycling fluorocarbons

Cash flow management is a key aspect of an enterprise's activity, as it is used to regulate all spheres of activity of a business entity, therefore issues related to the effectiveness of this process are of great relevance.
The article substantiates the theoretical basis, develops a methodical approach and practical proposals for improving the cash flow management system. The object of the study was the company's cash flow management processes. The subject of scientific research was the theoretical, methodical and applied aspects of cash flow management of the enterprise, as well as modern methods of its optimization.
An economic-mathematical model of multi-game optimization of the company's cash flows has been developed, which allows you to accumulate the necessary stock of cash assets in periods of high business activity and direct them in such a way that planned and necessary payments are made during the period of shortage of funds. The main criterion of the proposed model of cash flow optimization is the maximization of net cash flow from operating activities, which should ensure the development and expansion of the enterprise's activities on the basis of self-financing due to the growth of the areas of activity.
According to the proposed model, the optimal balance of cash assets, insurance, compensation and current stock of cash assets for a specific enterprise is determined. The proposed model makes it possible to accumulate the necessary stock of monetary assets in periods of high business activity and to direct them in such a way that in the period of shortage of funds, planned and necessary payments are made, as a result of the implementation of the model, it becomes possible to avoid attracting credit resources and related expenses, while receiving additional profit from investing temporarily free funds.
The information base of the study was made up of the fundamental theoretical provisions of economic science in the field of enterprise cash flow management, researched in the works of outstanding domestic and foreign economists, legislative and regulatory acts of Ukraine, government decisions and resolutions, N(S)BO, P(S)BO, financial reporting of Urozhai LLC.

The digital transformation is now a reality in Moldova, as Moldova has begun to transfer social, legal, and civil service delivery online. Sped-up digitalization can be expected to create new business models and opportunities for digital jumping in traditional industries. The Coronavirus crisis has highlighted the need for support and investments in digital transformation and effective digital governance, especially to guarantee the continuity and delivery of core government functions. The digital transformation is changing not just business models but the methods of production and distribution and the industry's competitiveness. The country's competitiveness is directly proportional to the country's level of economic development. According to SWOT analysis, general strengths on which Moldovan industry digitalisation will rely can be distinguished. It rely on the fact that manufacturing sector output is increasing – the contribution of the manufacturing sector to national GDP is around 12%, however it is on the lower side compared to other EU countries. Despite that, recent years indicate the rise of the output of this industry segment and industry digitisation will further encourage this process. Secondly, public and private IRT infrastructure is well-developed – is consistently updated, provides world-class internet access, and allows faster digitization. Thirdly, the growing capacity of digitization solutions providers - supply a wide range of services by participating in local and global value chains. The interview with experts who work closely in digitalization or competitiveness was done, and the SWOT analysis was done. Based on the research made, the recommendations for Moldova were prepared and presented in this article.
Holistic and multidisciplinary educational approach; A conceptual framework
Authors: Padmanabha C. H.
Published: April 2023

The NEP 2020 is the chief education policy of the twenty-first century, paving the way for a change from the 34-year-old National Policy on Education that was implemented in 1986. The initial pillars of NEP 2020 are Access, Equity, Quality, Affordability, and Accountability. It aims to transmute India into a flourishing information society and universal knowledge giant by making both school and college education more holistic, flexible, and multidisciplinary that will suit the 21st century and onward needs. It focuses on bringing out the individualistic and excellent capabilities of each child. A cursory glimpse of the policy causes apprehension with its attractive headlines and phrases. There is no doubt that this is an outstanding document with astonishing educational ideas, presented with a range of recommendations; some unique, some reiterated, and others reclaimed from earlier policy declarations. Terminologies and matter-of-fact imagination in the policy document seem to divert the attention of people and institutions away from the actual education world. As an investigator meticulously examines the policy's contents, one becomes more aware of the gap between key policy ideas and the present reality of education in India. This brief doctrine analysis aims to explore and exemplify some of the crucial thoughts of NEP 2020, which attempts to be holistic and multidisciplinary education. The present study has been undertaken keeping the following research questions in mind: Do we find any strong theories related to the multidisciplinary approach? What are the challenges of NEP 2020 with respect to holistic and multidisciplinary education? The present theoretical views are extremely useful for teacher educators, educational policymakers, and teachers.
The mediating role of unconditional self-acceptance in the relationship between perceived parental attitudes and forgiveness among university students
Authors: Ezgi Çağlar , Sinem Evin Akbay
Published: April 2023

The aim of the current study is to analyze the mediating role of unconditional self-acceptance in the relationship between perceived parental attitudes and forgiveness levels among university students. 1179 (753 females, 426 males) university students studying at Mersin University constitute the sample group for the study. Data was collected using the Volunteer Participant Form, the Parental Attitude Scale, the Unconditional Self-Acceptance Scale, and the Heartland Forgiveness Scale. Pearson correlation, descriptive statistics, an ordinary least squares regression-based approach, and the Bootstrap method were used to analyze the data. The results of the study found that there is a partial mediating role for unconditional self-acceptance in the relationship between perceived parental attitudes (authoritative, protective, and authoritarian) and forgiveness among university students. The mediating models tested in the study were also found to be statistically significant (p<.001). It was found that there is a significant mediating role of unconditional selfacceptance in the relationship between perceived authoritative parental attitudes and forgiveness levels of university students (F(2-1176)= 164.45, p<.001). The total variance explained by authoritative parental attitude and unconditional self-acceptance in the study is 47%. Similarly, it was found that there is a statistically significant mediating role of unconditional self-acceptance in the relationship between perceived protective parental attitudes and forgiveness levels of university students (F(2-1176)=163.54, p<.001), explaining 47% of the total variance. Lastly, it was concluded that the authoritarian parental attitude model is significant (F(2-1176)=158.51, p<.001), and that the authoritarian parental attitude and unconditional self-acceptance variables together explain 46% of the total variance in the study. The results were discussed and evaluated within the context of the research, and suggestions were made for further research to examine relevant variables.

The chemical, technological and allergy properties of goat’s milk are significantly
affected by the level of αs1-casein. Despite indications that more than 90% of cow’s milk
protein allergy (CMPA) children reacted similarly to goat's milk in typical IgE-mediated
forms, the availability of goat's milk without αs1-casein appeared to be a potential
alternative for patients with cow's milk allergy. In Malaysia, there is a lack of quantitative
data on αs1-casein in raw and commercial goat’s milk. To address this problem, this study
aimed to quantify αs1-casein in goat’s milk using reversed-phase high performance liquid
chromatography (RP–HPLC). The procedure was developed using a total of twenty
samples comprised of commercial and raw goat’s milk. For the calibration curve, a linear
relationship with R² > 0.999 was obtained using cow’s α-casein standard and peak areas
were observed over the concentration range, with a limit of detection (LOD) of 0.025 mg/
mL and limit of quantification (LOQ) of 0.075 mg/mL, respectively. The amount of αs1-
casein in the twenty samples ranged from 0.08±0.01 to 1.45±0.17 mg/mL. Three samples
which were claimed as goat’s milk infant formula were not found to contain αs1-casein.
Repeatability and reproducibility were satisfactory for both retention times and peak
areas. The RSD of peak areas ranged from 0.01 - 8.07% within an analytical day and from
0.61 - 1.77% across analytical days. This study will contribute as a reference method for
analysis and surveillance data of αs1-casein, in private or national laboratories, as well as
milk and milk product manufacturers.
