Constrained Probabilistic Continuous Review Inventory System with Mixture Shortage and Stochastic Lead Time Demand

This paper derives the probabilistic continuous review backorders and lost sales inventory system when the order cost is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead time demand follows some continuous distributions by using the Lagrangian method. Some published special cases are deduced and an illustrative numerical example with some graphs is added

Brain-based learning in design and visual arts education: a bibliometric assessment of Scopus indexed literature [version 3; peer review: 2 approved, 1 not approved]

Background: This study aims to critically review, quantify, and assess research outcomes on brain-based learning with an evidence-based study on Scopus indexed literature, with a focus to understand the evolution structure and growth, detect trends, subject development, and most importantly, identify the gaps in the published body of literature that relates brain-based learning to design and visual arts education. Methods: Various scientometric tools were used to map, visualize, and analyze 186 research publications, indexed in Scopus in a twenty-year timespan ‘2001-2021’. Annual publication trends, relevant sources, prolific authors, authorship patterns, productive organizations and countries, funding agencies, keyword co-occurrence analysis, and thematic evolution mapping on brain-based learning publications were examined in this study. Results: Despite the significance to apply brain-based learning strategies in design and visual arts education to boost students’ knowledge and creative skills, the findings show a decline in quantities and growth patterns in brain-based learning research directed towards design disciplines in the past twenty years. Among the identified (186) documents published in (128) sources, with (1013) citations, the study detected only (57) research (30%) that were related to ‘design education,’ including those focusing on ‘instructional design, ‘and ‘syllabus design’ whereas only (3) articles were in ‘design and visual arts’ disciplines. Conclusion: These rather small numbers reflect the big gap in the current body of literature that associates brain-based learning with creativity-based disciplines, specifically in design and visual arts education. This infers the necessity to direct the attention of academics, researchers, and educationalists in the fields of design and arts towards brain-based learning applications, research and pedagogy

Assessment of literature growth in Anthropometric measurement research: A bibliometric analyses of Scopus indexed publications

Purpose: To evaluate the global published literature in anthropometric measurement research between 1971-2021. Anthropometry is the study of the size and shape of the human body generally refers to the measurements and data used to characterize the size of human users. Method: Scientometric and bibliometric tools applied to analyze the research published indexed in the Scopus database. The study focused on indices, namely annual research growth, impactful author, relevant source, country collaboration, productive organization, country, etc. MS Excel, Bibexcel, RStudio (Biblioshiny), Scientopy, CiteSpace, and VOSviewer are used for the quantitative analysis. Results: There is steady growth in the literature of 483 from 1971 till date. 2020 was the most productive year with 58 publications, more than thirteen hundred authors participated in the research, and three authored collaborations were found more popular. The journal articles are the most preferred form. Applied Ergonomics recorded as the highly impactful source, and the USA observed as the most productive country. The \u27National natural science foundation of China\u27 represented as the most active and potent funding agenc

Outcome of Rhabdomyosarcoma in First Year of Life: Children’s Cancer Hospital 57357 Egypt

Background. Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma in children. Fifty percent of RMS cases occur in the first 10 years of life and less commonly in infants younger than one-year old. These infants require adapted multimodality treatment approaches. Patients and Methods. We analyzed patients’ characteristics, treatment modalities, and the outcome for RMS infants treated at Children’s Cancer Hospital Egypt (CCHE) between July 2007 and December 2010 and compared them to patients above one year treated on the same protocol. Results. Out of the 126 RMS treated during this period, 18 were below the age of one year. The male: female ratio was 1.25 : 1. The median age at diagnosis was 0.7 ± 0.2 years. Most of the cases (27.8%) were presented in head and neck regions. The estimated 4-years failure-free survival and overall survival for infants were 49 ± 12% and 70 ± 12%, respectively. These failure-free survival rate and overall survival rate did not differ from those for older patients (P=0.2). Conclusion. Infants with RMS are a unique group of RMS who needs special concerns in tailoring treatment in addition to concerns regarding toxicity and morbidity in infants
