Training Program With Positive Psychology Techniques For Underachieving University Students’ Learned Helplessness And Psychological Flow, Mohamed S. Abdellatif Aug 2023

Training Program With Positive Psychology Techniques For Underachieving University Students’ Learned Helplessness And Psychological Flow, Mohamed S. Abdellatif

Information Sciences Letters

This study aims to investigate the effectiveness of a positive thinking training program in reducing learned helplessness and improving the psychological flow of academically underachieving university students. The experimental research involved an 11-member training group, with learned helplessness and psychological flow scales used to assess the participants. Wilcoxon tests were used for data analysis. The results showed that the training program had a significant positive effect on both learned helplessness and psychological flow immediately after the training. Additionally, the positive effects were sustained a month later during the follow-up period. The study provides valuable insights for stakeholders and researchers.

The Communication Methods Of The Receptionists And Their Influence On The Customers’ Retention: An Empirical Study On Private Hospitals In Libya, Yousf Ibrahim Aljoudimi Jun 2023

The Communication Methods Of The Receptionists And Their Influence On The Customers’ Retention: An Empirical Study On Private Hospitals In Libya, Yousf Ibrahim Aljoudimi

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

Retention of customers is a focal point of any business, and following a certain retention policy expresses how effective the marketing strategy is. Although the previous studies-especially in the context of the services- focused on how retention is affected by several variables under purchasing behavior theory, they did not address the effect of the communication methods of the receptionists, which play a vital role when communicating directly/indirectly with the customers from the very beginning, during, end served, and retention stages. Therefore, this study is an attempt to bridge this research gap. The main aim of the current study is to …

Future Dental Journal

Abstract

Background: Oral Squamous cell carcinoma (OSCC) is typically discovered at an early stage; nevertheless, regional lymph node metastases are prevalent; therefore, surgical excision of the primary tumor is commonly coupled with neck dissection and radiotherapy. Cancer cells become invasive by acquiring a mesenchymal phenotype, a process known as the epithelial-to-mesenchymal transition. Vimentin, α-SMA and TGF-β expressions are believed to take part in EMT and tumor progression. Aim: this work aimed to evaluate the expression of Vimentin, α-SMA and TGF-β on OSCC progression and hence propose potential role as potential prognostic markers or therapeutic targets.

Distal Cantilever Length Comparison In Esthetic Material For Hybrid Implant Prosthesis: An In Vitro Study., Sana Shams Eddin, Elie Jasser, Mohammad Chams Eddin, Carole Abi Ghosn Yared, Joseph Makzoumi, Paul Boulos

International Arab Journal of Dentistry

Objective: the assessment of distal cantilever length in implant supported infrastructure by comparing the load to fracture in two different framework esthetic materials (Zirconia and Polyetheretherketone (PEEK)) with two different cantilevers loading distances (10mm, 15mm). Material and methods: 20 frameworks were fabricated and divided into 4 groups (n=5): according to the material type Peek, zirconia, and according to the cantilever loading distance (10), or (15) mm and a load-to-fracture test was used until complete fracture of specimens occurs. Results: The effect of material type and cantilever loading distance were statistically significant for the mean load-to-fracture values (P< 0.05). The Zirconia group failed at higher fracture loads (817 N) than the Peek one (651 N). Frameworks with 10 mm cantilever loading distance failed at higher fracture loads than specimens with 15 mm. Conclusion: Peek is a suitable material for all-on-four framework reconstruction in specific situations, and there is a higher success rate when the distal cantilever length is kept at minimal value (10mm).


Management Of Pulpal Floor Perforation Using Biodentinetm : Case Report, Chaima Bouhajja, Mayada Jemâa, Mohamed Bassem Khattech May 2023

Management Of Pulpal Floor Perforation Using Biodentinetm : Case Report, Chaima Bouhajja, Mayada Jemâa, Mohamed Bassem Khattech

International Arab Journal of Dentistry

During endodontic treatment in multi-rooted teeth, furcation perforation refers to an opening in the pulpal floor, leading to a communication with the periodontal ligament space. A three-dimensional hermetic seal, with a biocompatible material, is a key point for the success of pulp floor perforation repair. MTA® has been considered, for a long time, as a gold standard in furcation perforation repair. Besides, BiodentineTM, when used for the same purpose, showed considerable performance and good results. The purpose of this paper was to report the management of an iatrogenic perforation of pulpal floor in the maxillary right first molar, using BiodentineTM.
