As social media becomes increasingly ubiquitous, many events are recorded and released on social media platforms, including chemical weapon attacks. We develop an objective tool in order to evaluate brief and unstructured social media videos for analysing sarin exposure from a civilian medical pathology perspective. We developed and validated this new questionnaire using a standardized procedure that includes content domain specification, item pool generation, content validity evaluation, a pilot study, and assessment of reliability and validity. In total, 51 sarin attacks and 48 matched videos were analysed. Cronbach's a for all 20 items was 0.75, which indicates adequate internal reliability. The test-retest reliability was 0.96, which indicates good internal reliability. The inter-observer intraclass correlation coefficient was 0.97. After verifying sampling adequacy with the Kaiser-Meyer-Olkin measure and the factorability of the items with Barlett's test of sphericity, a factor analysis was performed. According to the principal axis factoring, a six-factor solution explained 51.86% of the total variance. The receiver-operating characteristic curve analysis showed that the Video Score Questionnaire has a sensitivity of 0.817, a specificity of 0.478, and an efficiency of 65.3. Therefore, the Video Score Questionnaire is reliable and valid for evaluating sarin attacks from brief and unstructured social media videos. KEY POINTS Chemical weapons are still used as a method of warfare. Social media videos are an important source of information. We developed a validated scale which can analyse sarin exposure in short and unstructured videos.
Kenevir bitkisi, endüstri ve tıp gibi temel alanlarda kolay, ekonomik ve sağlıklı çözümler sunan bir
bitkidir. Başta kannabinoidler olmak üzere çok sayıda kimyasal madde içermektedir ve zengin bir ürün
yelpazesi vardır. Endüstriyel kenevir biyobozunur her çeşit plastik madde, kağıt-karton, ısı yalıtım ve
inşaat malzemeleri üretiminde, tekstil ve otomotiv sektöründe, gıda ve kozmetik ürünlerin imalatında
ve biyodizel üretiminde kullanılmaktadır. Medikal kenevir kemoterapiye bağlı bulantı-kusma, kanser ile
ilişkili nöropatik ağrı, multipl skleroz ile ilişkili spastisitede, HIV’li hastalarda kilo alımında ve epilepsi gibi
bazı hastalıkların tedavisinde kullanılmaktadır.
Bu yazıda, eski uygarlıklar tarafından kullanılmış olup kültürümüzde önemli bir yere sahip olan ve son
yıllarda popülerlik kazanan tıbbi ve endüstriyel kenevir bitkisinin dünden bugüne kullanımı, yetiştirilmesi,
tıp ve endüstrideki yeri hakkında bilgi verilmesi ve aynı zamanda kenevirin ekonomik potansiyelinin
ortaya koyulması amaçlanmıştır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
