An interactive web application for propensity score matching with R shiny; example of thrombophilia
Demir, Emre; Köse, Serdal Kenan; Akmeşe, Ömer Faruk; Yıldırım, Engin
Aim: The aim of this study was to develop a new web-based R Shiny package that calculates propensity score using many algorithms such as logistic regression, machine learning, and performs matching analysis with balance evaluation. In addition, it was aimed to explain the process of matching analysis on a real data set by comparing the number of live births between those with methylenetetrahydrofolate reductase (MTHFR) homozygous mutations and those without mutations in women hospitalized due to abortion in the gynecology and obstetrics clinic. Material and Methods: The web-based application was developed using R shiny. The “matchIt” library was used for matching analysis and PS prediction. The “cobalt” library was used to evaluate balance and generate plots. Results: The abortion variable, which was statistically significantly different in the groups before matching (p=0.010), was similar in the groups after matching (p=0.743). In addition, when the descriptive statistics and p values of the other variables were examined, it was seen that almost full balance was achieved after matching and the confounder variables were similar distributed in groups. After matching analysis, it was determined that the result variable “livebirths” did not show statistically significant difference in the groups (p=0.864). Conclusion: In this study, we developed an interactive web application for matching analysis based on propensity score. It is thought that this application will facilitate the studies of the researchers.

Background: The global prevalence of allergic diseases has increased dramatically in recent years and are now recognized as significant chronic diseases worldwide. One of the most important allergens that causes allergic diseases is house dust mites. Objective: This study aims to present a bibliometric overview of research published on dust mites between 1980 and 2018. Methods: Articles published from 1980 to 2018 were analyzed using bibliometric methods. The keywords ?Dust mite*,? and ? Dermatophagoides ? were used in the Web of Science (WoS). Simple linear regression analysis was used to estimate the number of future publications on this subject. Results: A total of 4742 publications were found, 2552 (53.8%) of them were articles. Most of the articles were on subjects related to immunology (1274; 49.9%) and allergy (1229; 48.1%). Clinical and Experimental Allergy (222; 8.7%) was the journal with the most publications. The USA was the country that most contributed to the literature with 461 (18.1%) articles. The countries producing the most publications on this subject were developed countries. The most active author was W.R. Thomas (66; 2.5%). The most productive institution was the University of Western Australia (91; 3.6%). The most cited article was published in the New England Journal of Medicine .Conclusion: According to the findings, developed countries were the most productive in publishing on house dust mites. By planning multinational research rather than regional studies, it may be suggested that researchers in underdeveloped or developing countries could also-conduct more research on this subject.(C) 2019 SEICAP.

It is seen that distance education method which is a rationalist, contemporary and innovative education system, is started to be used widely with transportation of education and training activities to internet area fast, in recent years. Also, distance education contributes to human’s lifelong learning through giving education opportunities to working people whose financial situation and time are limited. With the development of information technologies in the world and Turkey, distance education methods and techniques also developed. Also the more the number of students taking part in distance education rises, the more the number of institutions giving distance education rises. Needs for preparing contents and managing these contents for lessons given by distance education method appeared with this raise. On this study, a platform has been developed for lecturers to create lesson contents and the efficiency of developed implementation has been analyzed statistically. It is aimed on distance education to design an efficient content development system through thinking the roles such as lecturers, managers and students; Son yıllarda eğitim öğretim faaliyetlerinin hızla internet ortamına taşınmasıyla akılcı, çağdaş ve yenilikçi bir eğitim sistemi olan uzaktan eğitim yönteminin yaygın olarak kullanılmaya başlandığı görülmektedir. Ayrıca uzaktan eğitim, zamanı ve maddi olanakları kısıtlı olan çalışan insanlara eğitim imkânı vererek bireyin yaşam boyu eğitimine de katkı sağlamaktadır. Dünya’da ve Türkiye’de bilişim teknolojilerinin gelişimiyle beraber uzaktan eğitim yöntem ve teknikleri de gelişim göstermiştir. Ayrıca uzaktan eğitime katılan öğrenci sayısıyla beraber uzaktan eğitim veren kurum sayısı gün geçtikçe artış göstermektedir. Gerçekleşen bu artışla birlikte uzaktan eğitim yöntemiyle verilen dersler için içerik hazırlama, bu içerikleri yönetme ihtiyacı ortaya çıkmıştır. Bu çalışmada, öğretim elemanlarının ders içeriklerini oluşturabilecekleri bir platform geliştirilmiş ve geliştirilen uygulamanın verimliliği istatistiksel olarak analiz edilmiştir. Uzaktan eğitimde eğitmen, yönetici ve öğrenci gibi roller düşünülerek etkin bir içerik geliştirme sistemi tasarlanması amaçlanmıştır.

Recently the numbers of distance education programs and students enrolling in them have increased significantly. This increase also carries the question of what factors may have an effect on academic success. The demographic features, motivation levels, personal development status and basic computer literacy of students have been taken into account and their effects on the academic success of students have been analyzed. With this purpose, surveys prepared with the help of professional opinion have been applied to certain groups. The sample group of
this study consists students of the Kırıkkale University Distance Education Center and the formal education students of the Kırıkkale Vocational School. The results have been analyzed with the help of the SPSS data analysis program (version 22.0) and have been turned into figures. The academic success of distance learning students and formal education students have been compared and this data has been used to identify whether there are any significant connections between academic success and the factors determined. In the conclusion of this study, the figures have been explained separately, and suggestions have been made regarding both distance education and formal education.; Son zamanlarda, yüksek öğretim kurumlarında çok sayıda uzaktan eğitim programının açıldığı ve kayıtlı öğrenci sayılarında ciddi artışlar olduğu gözlenmektedir. Uzaktan eğitimde öğrenci sayısındaki artışlar eğitimde başarıyı etkileyebilecek faktörlerin neler olabileceği sorusunu beraberinde getirmektedir. Bu çalışmada, uzaktan ve örgün eğitim öğrencilerinin demografik özellikleri, motivasyon seviyeleri, kişisel gelişim durumları ve temel bilgisayar kullanım seviyelerinin akademik başarılarına olan etkisi araştırılmıştır. Bu amaçla, uzman görüşleri alınarak anket soruları hazırlanmış ve gruplara uygulanmıştır. Araştırmanın örneklemini, Kırıkkale Üniversitesi Uzaktan Eğitim Merkezinde eğitim alan öğrencilerle Meslek Yüksekokulun’da örgün olarak öğrenim gören öğrenciler oluşturmaktadır. Anket soruları SPSS (versiyon 22.0) veri analiz paket programı ile analiz edilerek sonuçlar çizelgeler halinde verilmiştir. Uzaktan ve örgün eğitim alan öğrencilerin akademik başarıları ile araştırılan değişkenler arasında anlamlı bir farklılık olup olmadığı tespit edilerek analiz kısmında verilmiştir. Çalışmanın sonuç bölümünde elde edilen çizelgeler yorumlanarak uzaktan ve örgün eğitim birimlerine, ayrı ayrı öneriler sunulmaktadır.
