Knowledge Management And Organizational Performance: A Research On Systematic Literature

Studies that investigate the KM and organizational performance are few. The purpose of this study is to review the literature and review the articles related to the effect of knowledge management (KM) on organizational performance. A systematic literature review was conducted, and three screenings were performed to refine the articles. Article were extracted from Scopus and Web of Science (WoS). A total of 29 articles were considered to meet the selection criteria was reviewed, analyzed, and important information was extracted. A frequency analysis was conducted on these articles. The findings indicated that majority of the articles were extracted from WoS and published between 2015-2017 in Malaysia and Taiwan. The reviewed studies were conducted on manufacturing and technological industries using quantitative method. Sample size in most studies is less than 200 and data was analyzed using first generation of data analysis. Findings were discussed, and it was recommended for future studies to increase the sample size and use more frequently structural equation modeling

ENDO-RESTORATIVE RELATIONSHIP

Introduction: The primary goal of endodontic therapy is to prevent and treat apical periodontitis. Proper cleaning and shaping of canals, irrigation, and coronal seal are essential to achieving this goal while restorative dentistry aims to restore teeth to comfort, function and aesthetics. The relationship between restorative dentistry and endodontic has been established although the concepts related to treatment plans is ambivalent. With the advent of advanced dentistry, emphasis should be given on restorability of teeth before endodontic treatment. The aim of work: The review focuses on the decision in treatment planning and endodontic-restorative interface to best restore teeth following endodontic treatment. Methodology: We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, January 1985, through February 2017. The following search terms were used: Endodontic treatment, Restorative dentistry, Post and Core Conclusion: With the emergence of advanced dentistry such as implants, more emphasis is given on long-term outcome of treatment thus evaluation of restorability of teeth before endodontic treatment is important. The treatment is not well served if tooth fails despite successful endodontic treatment. Keywords: Endodontic treatment, Restorative dentistry, Post and Core

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
