Published: February 2023

The Catharanthus roseus plant was extracted and converted to nanoparticles in this work. The Soxhlet method extracted alkaloid compounds from the plant Catharanthus roseus and converted them to the nanoscale. Chitosan polymer was used as a linking material and converted to Chitosan nanoparticles using Sodium TriPolyPhosphate (STPP). The extracted alkaloids were linked with Chitosan nanoparticles CSNPs by maleic anhydride to get the final product (CSNPs- Linker- alkaloids). The synthesized (CSNPs- Linker- alkaloids) was characterized using SEM spectroscopy UV–Vis., Zeta Potential, and HPLC High-Performance Liquid Chromatography. Scanning electron microscope (SEM) analysis shows that the Chitosan nanoparticles (CSNPs) have small dimensions with regular spherical and nanotube shapes of a diameter range of (49 - 70) nm. The final product (CSNPs- Linker- alkaloids) has two shapes (spherical particles and tubes) in nano dimensions and is close to each other compared to normal Chitosan. The absorption peaks for Chitosan (CS), Chitosan nanoparticles (CSNPs), Chitosan nanoparticles (CSNPs), and maleic anhydride revealed that converting Chitosan to Chitosan nanoparticles and mixing it with the plant extract, led to an increase in the absorption value and wavelength range. Also, the appearance of two peaks at 222 nm and 402 nm nano instead of the peak of Chitosan at 289.9 nm. Zeta Potential results of CSNPs- Linker- alkaloids showed that the extract of the nano-alkaloids bound to chitosan nanoparticles carries a positive charge of 54.4 mV. This surface charge is essential in maintaining the colloidal solution's stability in its natural form without changing. High-Performance Liquid Chromatography (HPLC) was used to estimate qualitative and quantitative plants extracted from Catharanthus roseus. Quantitative HPLC results show that Catharanthus roseus contains a good and acceptable concentration of Vinblastine, Vincristine, Vinorelbine, Vincamine, and Vintafolide (66.75, 242.91, 0.7, 83.77, 42.34) ppm respectively. The qualitative results show a good match for the influential groups of pure standard vincristine and alcoholic extract and dry powder of the Catharanthus roseus plant. The successful synthesis of nanoparticles from the Catharanthus roseus plant can be used in biosensors and biomedical applications.

Authors: Gooneratne D. W. A. , De Silva W. B. S. V.
Published: February 2023

All the nations around the world are interrelated and interdependent through economic, cultural, social, and, technological means. The foreign exchange market and the stock market are the driving forces of global interdependency. Thus, the study aims to analyze the nature of the relationship between foreign exchange rates and the stock market performance in the Sri Lankan context. The study adopted a quantitative research approach where publicly available secondary data from the Central Bank of Sri Lanka and the Colombo Stock Exchange were used for the analysis. All Share Price index was used as the dependent variable and the monthly average exchange rates; USD/LKR, GBP/LKR, EUR/LKR, JPY/LKR, and INR/LKR were used as the independent variables. The study gathered data for 19 years from Jan’2000 – Jan’2019, where the data set was tested for unit root, and given the non-stationary nature of data; the Johansen co-integration rank test was applied. The study findings depict a non-significant relationship between the exchange rates and the stock market performance in the Sri Lankan context emphasizing the absence of a long-term relationship. This is of paramount importance for both local and foreign investors given the decisions on foreign exchange risk hedging and the portfolio performance depend on this relationship. To the best of our knowledge, this is one of the early studies in Sri Lanka to identify the association between exchange rates and stock returns over a period of 19 years.

Authors: Ranatunga R. V. S. P. K. , Jayasekara M. D. R. , Priyanath H. M. S.
Published: February 2023

The primary concern of this study is to examine how Information & Communication Technology (ICT) usage and dynamic capabilities impact the business resilience of Small and Medium Scale Enterprises (SMEs) to survive and continue during the COVID-19 pandemic. The data were collected from a sample of 129 ICT-used SMEs employing face-to-face and telephone interviews. Partial Least Square-Structural Equation Modelling (PLS-SEM) was used to analyse the data through SmartPLS software. The study findings reveal a significant positive relationship between ICT usage and business resilience during the pandemic. And ICT usage significantly affects the dynamic capabilities of the business. Results also claim that dynamic capabilities play a complementary mediating role in the relationship between ICT usage and business resilience. Consequently, the study concludes that the adoption of ICT and the ability to integrate, build and reconfigure the available resources of SMEs with ICT enablers enhanced their resilience and ensured survival during the pandemic. The research design, the methodology utilized, and the findings of this study will benefit researchers, policymakers, and entrepreneurs and contribute to future studies regarding the regrowth and resilience of SMEs during a crisis.

Authors: Crossway Ashley K. , Rogers Sean M. , Hansen Anisa , Sturtevant Jennifer , Moffit Dani M. , Lopez Rebecca M.
Published: February 2023

Recently, with discriminatory legislation efforts and changing participation policies in organized sports, media attention surrounding transgender and gender-diverse (TGD) individuals has increased. These changes and the historical lack of competence and education regarding the transgender patient population have resulted in subpar patient care and a misunderstanding of the athletic trainer’s (AT’s) role within the health care and compliance systems. This literature review is the second part of a 2-paper series, and our objective was to educate ATs on the processes relevant to medical affirmation, including compliance considerations regarding medical eligibility, and to establish the AT’s role.

The gender affirmation framework includes social and legal components, which are discussed in part 1 of this literature, and the medical component is thoroughly discussed in part 2. All health care providers involved in the care of TGD individuals should work collaboratively on an interprofessional care team and have a general knowledge of the gender-affirmation process, including gender-affirming hormone therapy, surgical options, known risks and complications, and the general health needs of TGD patients. With this knowledge, ATs, as point-of-care providers and members of the interprofessional care team, are uniquely positioned to help reduce health and health care disparities. Furthermore, ATs can use their knowledge to facilitate medical compliance and eligibility in the evolving policies of sporting organizations.

Authors: Horn-Lodewyk Je'nine , Wainwright Tanya , Lessing K-Cee , Otto Daniel , Fourie Jani H.
Published: February 2023

Background: Theatre personnel can spread healthcare-associated infections through contaminated surgical scrubs. Decontamination of surgical scrubs through optimal methods is important to minimise transmission of microorganisms from theatre personnel’s clothing to different areas in the hospital and their homes.Aim: This study aimed to review the literature on the optimal home and hospital laundering methods for the decontamination of reusable surgical scrubs worn by theatre personnel.Method: A systematic literature review of previous studies on laundering reusable surgical scrubs was performed. A review question was formulated using the patient, intervention, comparison and outcome (PICO) framework. A literature search was performed using ScienceDirect, Web of Science, ProQuest, EBSCOhost and Google Scholar.Results: A direct link could be established between the cycle length and water temperature. The higher the water temperature, the shorter the washing cycle required. After a load has been washed in low or medium water temperatures, tumble drying and ironing should follow. Despite the water temperature, a disinfectant must be added to the load.Conclusion: Health professionals and hospital management should be aware of optimal laundering guidelines for hospital and home laundering as part of infection control. Water temperature, time, mechanical action, type of disinfectant and heat are factors influencing the successful removal of bacteria and other pathogens and represent the baseline of this article.Contribution: Home-laundering of reusable surgical scrubs should follow strict guidelines. When these specific guidelines are applied, the effects of home-laundered scrubs will not negatively impact either the theatre or the home environment.

Authors: Khan Amaarah , Patel Ammaarah , Noorbhai Habib
Published: February 2023

Background: The coronavirus disease 2019 (COVID-19) lockdown was a strange and new occurrence, which left many individuals ill-equipped to cope with the new way of living. Sportspersons had to adapt to a new training style within a new environment, both physically and mentally.Aim: The purpose of this study was to understand the physical, mental and emotional parameters among sportspersons during the COVID-19 lockdown regulations.Setting: The study consisted of 105 regular sportspersons (from South Africa).Methods: This was a quantitative research study design using an online questionnaire. An online questionnaire was adapted and distributed via online social platforms (WhatsApp, Twitter and Instagram) to collect data in which sportspersons (n = 105) answered questions about the effects that they experienced during lockdown on their physical, mental and emotional well-being.Results: Sportspersons participated in cardiovascular training, flexibility training, strength training and bodybuilding exercises during pre-lockdown. During lockdown, more than 74% of sportspersons had adequate training space, equipment and the time to perform physical activity. However, more than 43% of these sportspersons experienced a decrease in flexibility, muscle mass and muscle strength. Exercise was used as a form of stress relief by 77.1% of sportspersons throughout lockdown. In addition, sportspersons who used exercise as a form of stress relief continued to experience an increase in stress throughout lockdown.Conclusion: The outcomes from this study demonstrated how the COVID-19 lockdown had adverse effects on the overall health and well-being of most sportspersons. Other outcomes included the effects that physical inactivity had among sportspersons, including changes in diet and sleep.Contribution: This study highlights the urgency for the sports fraternity to adopt measures to provide various methods of stress relief (as well as opportunities for physical activity) during similar periods of lockdown (or exercise restrictions) for those who rely on exercise as their daily physical, mental and emotional outlet.
Nurturing agency in emerging adults of local churches: a case study from Soshanguve
Authors: Kabongo Kasebwe T. L.
Published: February 2023

Emerging adults (age 35 and below) are the majority of the African population. In South Africa, for example, emerging adults make 63.9% of its population. This age group seems to be marginalised in Christian congregations of the township of Soshanguve where this research was conducted. This research is a case study that interviewed 30 de-churched emerging adults from different denominations to make its conclusions. It is stressing how the church could see the emerging adults’ empowerment as its contribution to building an inclusive society. It was found out that many people under the age of 35 years are leaving their local churches because they feel that their voices are undervalued, and they do not have fulfilling roles to play. It was concluded that some de-churched emerging adults are eager to exercise their agency in making their voices heard and playing fulfilling roles in a missional community structure outside their previous congregations. Many others just complained about the marginalisation they experienced in their previous congregations, but they did not exercise their agency to help build a church they would love to be part of. Marginalisation could, therefore, be an opportunity to create an inclusive community. It could also remain an eternal wound for other people who may just be finger-pointing perpetrators of marginalisation without demonstrating a different praxis.Contribution: This is a practical theology article that is strengthened by sources from political sciences and development studies to stress the need for the church to model inter-generational inclusiveness in how it operates.

Authors: Zhang Chi-Chen , Tu Xiang , Lin Tian-Hai , Cai Di-Ming , Yang Ling , Qiu Shi , Liu Zhen-Hua , Yang Lu , Wei Qiang
Published: February 2023

We attempted to perform risk categories based on the free/total prostate-specific antigen ratio (%fPSA), prostate-specific antigen (PSA) density (PSAD, in ng ml−2), and multiparametric magnetic resonance imaging (mpMRI) step by step, with the goal of determining the best clinical diagnostic strategy to avoid unnecessary tests and prostate biopsy (PBx) in biopsy-naïve men with PSA levels ranging from 4 ng ml−1 to 10 ng ml−1. We included 439 patients who had mpMRI and PBx between August 2018 and July 2021 (West China Hospital, Chengdu, China). To detect clinically significant prostate cancer (csPCa) on PBx, receiver-operating characteristic (ROC) curves and their respective area under the curve were calculated. Based on %fPSA, PSAD, and Prostate Imaging-Reporting and Data System (PI-RADS) scores, the negative predictive value (NPV) and positive predictive value (PPV) were calculated sequentially. The optimal %fPSA threshold was determined to be 0.16, and the optimal PSAD threshold was 0.12 for %fPSA ³0.16 and 0.23 for %fPSA <0.16, respectively. When PSAD <0.12 was combined with patients with %fPSA ³0.16, the NPV of csPCa increased from 0.832 (95% confidence interval [CI]: 0.766–0.887) to 0.931 (95% CI: 0.833–0.981); the detection rate of csPCa was similar when further stratified by PI-RADS scores (P = 0.552). Combining %fPSA <0.16 with PSAD ³0.23 ng ml−2 predicted significantly more csPCa patients than those with PSAD <0.23 ng ml−2 (58.4% vs 26.7%, P < 0.001). Using PI-RADS scores 4 and 5, the PPV was 0.739 (95% CI: 0.634–0.827) when further stratified by mpMRI results. In biopsy-naïve patients with PSA level of 4–10 ng ml−1, stratification of %fPSA and PSAD combined with PI-RADS scores may be useful in the decision-making process prior to undergoing PBx.
Mammaglobin immunoexpression in some malignant salivary gland neoplasms as a potential diagnostic tool for tumor ductal differentiation
Authors: Zaid Basant H. Abou , Wahba Omneya M. , Youssef Heba E. M.
Published: February 2023

Introduction

Despite being a rare daily histopathologic diagnosis, malignant salivary gland (SG) tumors show significant morphologic diversity that could obscure their diagnosis. Recognizing specific microscopic patterns together with the aid of ancillary techniques, such as immunohistochemistry, represent the clues to precise diagnosis. Mammaglobin (MMg) is a member of secretoglobin protein family that is widely associated with breast cancer and strongly expressed by secretory carcinoma of SGs. Its expression in other malignant SG neoplasms should be investigated.

Objectives

Investigating the immunohistochemical expression of MMg in some malignant SG tumors to detect its potential diagnostic value.

Material and Methods

Nineteen paraffin-embedded, archival specimens of malignant SG tumors were divided into two groups according to presence or absence of ductal differentiation. Specimens were immunohistochemically stained using anti-MMg protein.

Results

MMg expression was more upregulated in the ductal differentiation group as compared to the other group of neoplasms.

Conclusion

MMg would represent a promising diagnostic tool in discriminating SG tumors with ductal and/or secretory activity.
Comparison between maxillary skeletal expander and hybrid hyrax facemask combination in treatment of growing patients with skeletal class III malocclusion
Authors: Ragab Rehab Shehab El-Deen Ali , El Shennawy Mahmoud I. , Yousif Atia A. E. W.
Published: February 2023

Introduction

It has been demonstrated that the use of skeletal anchoring devices for maxillary protraction is a potential method for treating growing patients with class III malocclusion caused by maxillary retrognathism. The aim was to compare the skeletal and dentoalveolar effects of maxillary skeletal expander and hybrid hyrax facemask combination in the treatment of developing skeletal class III malocclusion.

Patients and methods

The study comprised 30 developing class III participants randomly selected with maxillary retrognathism in the late mixed or early permanent dentition. In group 1 (n = 10) patients, the maxillary skeletal expander facemask technique was utilized. In group 2 (n = 10) patients, the hybrid hyrax facemask technique was utilized. Group 3 (n = 10) patients, a control with no treatment group. Analysis of pretreatment and posttreatment cephalometric radiographs was used to evaluate skeletal changes.

Results

The treatment periods for groups 1 and 2 were 8 and 8.5 months, respectively, whereas the untreated control group was followed for 9 months. In comparison to the untreated control group, the maxilla shifted markedly forward in groups 1 and 2 (4.65 mm in group 1 and 3.72 mm in group 2); overjet was improved without proclination of the upper incisors. However, group 2 had more mandibular opening rotation than group 1.

Conclusion

The two maxillary protraction protocols effectively corrected the significant maxillary deficiency in developing class III patients. However, vertical alterations were better controlled by the maxillary skeletal expander facemask combination (group 1), thus it can be used to treat developing class III patients with a hyperdivergent growth pattern.
Effect of the commercially available whitening agents on the microshear bond strength of resin composite restoration
Authors: Mubarak Rania Z.
Published: February 2023

Objective

The aim of the present study was to evaluate the effect of whitening agents on the bond strength of resin composite repair. This study was also carried out to compare the bond strength of a solvent-free self-etch adhesive to that of two different self-etch adhesives.

Materials and method

Twenty-seven discs were prepared using resin composite, which were assigned into three groups (n = 9). The first group was used as control. The other discs were divided into 2groups according to the whitening agent utilized, Crest 3D White Strips Advanced Vivid and Colgate Visible White 9% Mint applied once a day for 14 days. Each group was further subdivided into 3 subgroups (n = 3) according to the adhesive system used, [solvent-free self-etching adhesive system], [self-etching adhesive system], and [self-etching adhesive system]. Microcylinders were constructed, microshear test was performed and the data was registered in MPa.

Results

The whitening agent, the adhesive resin system and the interaction between the variables had a significant effect on the bond strength (P ≤ 0.05). [Solvent-free self-etching adhesive system] and [Self-etching adhesive system] performed similarly, where both showed significantly highest mean microshear bond strength values. Whereas, [self-etching adhesive system] showed the statistically lowest mean bond strength. The highest mean bond strength was found without whitening agent, thenColgate visible white, while Crest 3D white strips showed the lowest bond strength values.

Conclusion

It was concluded that the tested whitening agents reduced the bond strength, with comparable performance of both (solvent-free self-etching adhesive system).

A Secondary Analysis of Short- and Long-Term Variability of Inspiratory Muscle Performance in People Living With SCI
Authors: Palermo Anne E. , Cahalin Lawrence P. , Nash Mark S.
Published: February 2023

Objectives

To explore the expected variability in repeated short-term (ST) and long-term (LT) inspiratory muscle performance (IMP) in individuals with chronic spinal cord injury (SCI).

Methods

Maximal inspiratory pressure (MIP), sustained MIP (SMIP), and inspiratory duration (ID) were collected from 22 individuals with chronic SCI (C1-T9, American Spinal Injury Association Impairment Scale [AIS] A–C) over 18 months. ST data were collected four times within 2 weeks (n = 19). LT data were collected at two time points at least 7 months apart (n = 20).

Results

SMIP was the most reliable IMP assessment with an intraclass correlation coefficient (ICC) of 0.959, followed by MIP (ICC 0.874) and ID (ICC 0.689). The ID was the only ST measure to have a significant difference [MIP: F(3, 54) = 2.5, p = .07; SMIP: F(3, 54) = 1.3, p = .29; ID: F(1.4, 25.6) = 4.8, p = .03]. Post hoc analysis showed the mean day 1 ST ID measure was significantly different from both days 3 and 4. The percent change of ID from day 3 to day 6 was 11.6%. No LT measures differed significantly [mean change (SD) [95% CI] for MIP: 5.2 cm H2O (18.8) [−3.6, 13.9], p = .235; SMIP: 60.9 pressure time unit (166.1) [−16.9, 138.6], p = .118; ID: 0.1 s (2.5) [−1.1, 1.3], p = .855].

Conclusion

These data provide a foundation for understanding normal variance in ST and LT IMP in the SCI population. Change in MIP function outside 10% is likely a true and meaningful change and may help clinicians recognize individuals with SCI at risk for respiratory compromise. Future studies should explore changes in MIP and SMIP that are associated with meaningful functional changes.

This article is devoted to the analysis of the relationship between fiction and History in the female novel of post-independence. In the text La femme sans sepulture by Assia Djebar, the voices of women living daily with commitment, the war of national liberation, fear and tragedy, recount and report, in a commemorative journey, the true story of heroine Zoulikha Oudai. But this time, the narrator (the author) becomes the "guest", "the visitor" or the "listener", who, melted into the chorus of tellers,  at times mixes her memories and participates in the work of reconstitution and of the rehabilitation of History, and at other times is silent to better listen to the confidences and testimonies of the women of Caesarea.

Résumé :

Ce présent article est consacré à l’analyse des rapports de la fiction et de l’Histoire dans le roman féminin de la post-indépendance.  Dans le texte La femme sans sépulture d’Assia Djebar, des voix de femmes vivant au quotidien l’engagement, la guerre de libération nationale, la peur et la tragédie, racontent et rapportent, dans un parcours remémoratif, l’histoire vraie de l’héroïne Zoulikha Oudai. Mais cette fois, la narratrice (l’auteure) devient "l’invitée", "la visiteuse" ou "l’écouteuse", qui, fondue dans le chœur des diseuses, tantôt mêle ses souvenirs et participe au travail de la reconstitution et de la réhabilitation de l’Histoire, tantôt se tait pour mieux écouter les confidences  et les témoignages des femmes de Césarée.
Teacher Training in the Post-Colonial Era (from 1962 - 2000 and up)
Authors: Lansari Wassila Chahrazede Chahineze , HADDAM BOUABDALLAH Faiza
Published: February 2023

Any educational system worldwide has always given importance to preparing novice teachers during their first steps as teachers, not least EFL teachers. Though this training has witnessed many changes, the concept has been the same: to equip beginner teachers with professional traits and skills to deal with their learners in an everyday classroom. In Algeria, the development of the training system has continued since its independence in 1962. It has undergone different processes and reforms, from one-day training to a year's preparation to improve teachers' competencies. This paper aims to shed light on teacher training from Algerian independence till the new millennium. Education experts have recently become aware of the importance of professional preparation for teachers to combine theory with real-world experience. Many scholars see novice teachers' training as a way of inculcating specific outcomes for teachers' qualifications due to the misconception of the program set for them. On the contrary, a healthy-designed program has to benefit those teachers with career development and enough awareness that teachers must continuously make research and update their teaching to have a deep understanding about themselves and their learners. Teachers should be aware that self–development in the profession does not have an end even when training stops.
Résumé
Tous les systèmes éducatifs à travers le monde ont toujours donner de l’importance à la préparation des enseignants stagiaire pour les accompagné dans leur premier pas dans la profession, et l’enseignement de L’anglais comme une langue étrangère n’est pas en reste. Cependant, le stage de formation a connu certains changements mais le concept est resté le même, c’est d’équipé les stagiaires avec un baguage professionnel et des compétences pédagogique nécessaire pour réussir dans la profession. En Algérie la méthode de stage à beaucoup évolué et a connue plusieurs reformes, depuis l’Independence. L’objectif de cette article est de montrée le parcours du stage en Algérie à partir de l’indépendance jusqu’au nouveau millénaire. Les experts ont constaté que cette préparation de stagiaires est bénéfique pour accéder à un enseignement meilleur afin de pouvoir appliquer la théorie, apprise à l’université, sur le terrain avec les apprenants. Les stagiaires vont bénéficier de ce stage afin d’améliorer leur compétence au sein de leur classe et faire aussi leur propre recherche en fonction des besoins des étudiants. Ainsi, les stagiaires vont avoir conscience que le stage et juste un outil qui permet de les guider durant la première année et c’est à eux de continuer leur chemin en ayant un but précis qui est toujours comment faire passer le message en classe pour que tous les apprenants développent leur compétence.

The theme of this volume comes out of a research project entitled “Gender, Language and Identity in (Post) Colonial Algeria”, which was crowned by two successful national conferences in 2019 and 2021. The idea to extend the scope of research from Algeria to African contexts is realised in the sixth volume of this journal. African countries share a common history of colonisation, struggle and war of independence. Likewise, all of them witnessed an alteration in their languages during colonisation and after. Articles related to gender, language situation and identity in African countries were called for in which authors highlighted aspects of race, religion, culture, art, literature and many other topics in the (post) colonial African contexts.

Nervous Developmental Disorder with Involuntary Movements (NEDIM) (OMIM 617493) is a rare movement disorder in children on the spectrum of GNAO1-associated movement disorders. With NEDIM, movement disorders appear in early childhood, progress and lead to disability. The disease is caused by pathogenic heterozygous variants in the GNAO1 gene and has an autosomal dominant mode of inheritance. The epidemiology of NEDIM has not yet been established. Clinical symptoms are extensive, ranging from severe motor and cognitive impairment with self-injurious behaviour and seizures to a mild phenotype of movement disorders without mental retardation and seizures. Some patients develop epilepsy. Hyperkinetic syndrome in most children is manifested with chorea, athetosis, dystonia, and ballism, affecting the muscles of the body, limbs and face. According to MRI, in some patients, gradually progressive atrophy of the brain substance is visualized. Currently, the disease has no developed pathogenetic methods of therapy. Treatment is symptomatic, including various drug regimens to reduce the severity of movement disorders and seizures. Management of nutrition of the patient and the prevention of secondary complications of movement disorders are also important. In foreign sources there is described the experience of using topiramate and teterabenazine, as well as deep brain stimulation (DBS), which demonstrate a good effect in the form of a significant reduction in the frequency of dystonic storms and the severity of motor disorders. The article presents a clinical case of diagnosis and treatment of a child with this disease, and also current trends in therapy.

Published: February 2023

Ecuador, al igual que otros países, está siendo afectado por el problema de la violencia, este problema no afecta sólo a las instituciones educativas de educación superior y a su nómina estudiantil, sino que se extiende a la sociedad. Algunos resultados de investigaciones realizadas indican que los estudiantes que experimentan o son testigos de violencia universitaria tienen más probabilidades de perpetuar comportamientos violentos. Por ello, el objetivo de la investigación consiste en identificar las causas y factores de la violencia escolar (Bullying). Para ello se aplicó un modelo propuesto por Everett & Price. La encuesta fue realizada por 70 estudiantes de la carrera de psicología de la Universidad Central del Ecuador. Se utilizó un método cuantitativo, dado que se recolectó y analizó datos arrojados a través de la aplicación del formulario. Finalmente, para realizar el estudio estadístico, se realizó un análisis factorial exploratorio porque nos permitirá explorar con mayor precisión las dimensiones subyacentes, constructos o variables latentes de las variables utilizadas, en otras palabras, las que observa y mide el investigador. Finalmente se concluyó que la violencia en las escuelas no puede ser ignorada. Si bien, muchos estudiantes pueden sentirse más seguros en las instituciones educativas, muchos se ven afectados negativamente por la violencia hasta el punto de que algunos planteles no son un lugar seguro que conduce al aprendizaje, sino un lugar que perpetúa la ira y el miedo.

Abstrak: Geometri fraktal, juga dikenal sebagai "geometri alam", adalah jenis geometri yang mempelajari geometri tidak beraturan. Karakteristik utama dari geometri fraktal adalah self-similarity, yaitu bagian lain dari fraktal memiliki bentuk yang serupa pada skala yang berbeda. Penelitian ini bertujuan untuk membangun pola fraktal berdasarkan bentuk dasar persegi dan menggunakan dua jenis transformasi affine, yaitu dilatasi dan translasi. Parameter yang dapat diubah untuk transformasi adalah skala. Implementasi pembuatan program dilakukan dengan menggunakan bahasa pemrograman Python. Dengan membandingkan hasil dari enam iterasi untuk skala 0,5 dan 0,45, diperoleh perbedaan secara visual baru terlihat jelas dari iterasi 3.Kata kunci: geometri fraktal, transformasi, persegiAbstract: Fractal geometry, also known as "natural geometry", is a type of geometry that studies irregular geometries. The main characteristic of fractal geometry is self-similarity, i.e. other parts of the fractal have a similar shape at different scales. This study aims to build a fractal pattern based on a basic shape of a square and use two types of affine transformations, which are dilation and translation. The parameter that can vary for the transformation is the scale. The implementation of making the program is carried out using the Python programming language. By comparing the results of the six iterations for a scale of 0.5 and 0.45, the visual differences are only clearly visible from iteration 3.Keywords: fractal geometry, transformation, square

Abstrak: Setiap tahunnya, di Indonesia jumlah penderita gangguan mata terus mengalami peningkatan. Beberapa jenis penyakit ini di antaranya katarak, kebutaan,  kelainan refraksi dan kornea. Penyakit mata perlu mendapatkan pemeriksaan dan pengobatan dari dokter spesialis mata untuk menghindari kerusakan yang lebih parah. Seiring perkembangan teknologi, Pekerjaan yang sangat sibuk dari seorang dokter mengakibatkan bidang sistem pakar mulai dimanfaatkan untuk membantu seorang pakar/ahli dalam mendiagnosa berbagai macam penyakit. Penelitian ini membuat sistem pakar berbasis web untuk diagnosa awal penyakit mata. Sistem dibangun menggunakan bahasa PHP dengan model Unified Modelling Langguage (UML). Metode forward chaining diterapkan pada inferensi untuk merunutkan gejala-gejala yang menghasilkan kesimpulan. Adapun certainty factor untuk mengetahui berapa persen penyakit yang di derita penderita melalui hasil hitungan dalam metode tersebut. Hasil pencocokan diagnosa menunjukkan bahwa 100% sesuai antara hasil sistem dan diagnosa pakar. Sistem ini dapat menjadi sistem diagnosa awal untuk mengetahui jenis penyakit mata yang dialami tanpa konsultasi kepada spesialis mata terlebih dahulu.Kata kunci: Sistem pakar, Certainty Factor, Forward ChainingAbstract: Every year, in Indonesia the number of patients with eye disorders continues to increase. Some types of this disease include cataracts, blindness, refractive errors, and corneal diseases. Eye disorders need to get an examination and treated by an ophthalmologist to avoid more severe damage. Along with technological developments, the busy life of an expert makes the field of expert systems begin to be used to assist an expert in diagnosing various diseases. This research creates a web-based expert system for early diagnosis of eye disease. The system is built using the PHP language with the Unified Modeling Language (UML) model. The forward chaining method is applied in inference to sequence the symptoms that result in conclusions. The certainty factor is used to find out what percentage of the patients suffer through the calculation of this method.  The results of matching diagnoses show that there is a 100% match between system results and expert diagnoses. This system can be an initial diagnostic system to determine the type of eye disease experienced without consulting an ophthalmologist first.
