The Effect of the Internet of Things (IoT) on Education Business Model

The introduction of the Internet of Things (IoT) in education, which allows Internet based communications to happen between physical objects, sensors and controllers, has changed educational institutions massively. By embedding sensors in objects and integrating cloud computing, augmented reality, wearable technologies and big data in this platform, different parameters of the educational environment can be measured and analysed to provide useful information. It also has created a new interaction between people and the environment in educational organisation. In this research based on the recent IoT projects in education, we will categorize the application of IoT in education into four groups: energy management and real time ecosystem monitoring, monitoring student’s healthcare, classroom access control and improving teaching and learning. We will investigate and analyse how this platform has changed the Education Business Model and added new value propositions in such organizations based on the Canvas Business Model

Psychological implications of coronavirus disease 2019 outbreak in patients with chronic diseases: A systematic review

BACKGROUND: During the coronavirus 2019 (Covid-19) pandemic, patients with chronic diseases faced many challenges like greater risk of Covid-19 and delay in treatment which increase the possibility of psychological problems in these individuals. In this regard, the present study was conducted to investigate the psychological consequences of the Covid-19 epidemic in this group of patients.METHODS: In this systematic review study, published articles on the psychological consequences of the Covid-19 outbreak in 2020 were reviewed. Keywords including Coronavirus 2019 (COVID-19), Psychological Implications, Epidemic, Mental Health, and Chronic diseases were searched in the title and abstract of articles published in reputable international scientific databases and all related English articles were listed and 30 qualified articles were reviewed.RESULTS: According to the collected data, loneliness increased stress and anxiety, and decreased sleep quality. Moreover, post-traumatic stress, panic attacks, and depressive and anxiety symptoms were the most important psychological consequences of the Covid-19 epidemic for people with chronic diseases. Female gender, old age, longer history of chronic disease, and lack of social support were associated with increased psychological problems. Increased fear and anxiety in caregivers and related health personnel were other results of the study.CONCLUSION: Many people with chronic illnesses have suffered from psychological problems during the outbreak of COVID-19. Furthermore, the extent of these problems depends on the characteristics of the chronic disease, and individuals’ demographic and ecological characteristics, which emphasizes the need for designing individualized programs

Isolation and phylogenetic analysis of zinc resistant Acinetobacter sp. and its potential for bioremediation

In this study, a gram negative, non- motile short rod-shaped and heavy metal resistant bacterial strain was isolated from effluents. The optimum temperature and pH for the growth of the strain were 33°C and 7, respectively. The minimum inhibitory concentrations (MICs) of zinc (Zn), copper (Cu), chromium (Cr) and mercury (Hg) against the isolate were determined. The isolate showed MICs of 5, 4, 3 and 2 mM when grown on Zn, Cu, Cr and Hg, respectively. The isolate was assessed for its ability to remove zinc from medium amended with different concentrations of zinc. Up to 65% of zinc was removed at the zinc concentration of 1 mM. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belongs to the genus Acinetobacter with 98% similarity to Acinetobacter junni. It was then designated as Acinetobacter sp. HM_AF14. Based on the data obtained in this study, it can be concluded that Acinetobacter sp. HM_AF14 can be used for bioremediation of zinc from effluents.Keywords: Heavy metals, Acinetobacter sp., bioremediation, 16S rRNA, zinc removalAfrican Journal of Biotechnology Vol. 12(26), pp. 4123-412

Investigating the Emotional Theory of Mind in Iranian Married Women: A Descriptive Phenomenological Study

In marital relationships, the type of perception of the spouse’s behavior affects how the social information and behavior of the other couple is processed, leading to psychological consequences. Thus, a higher perception of each other’s mental state is followed by sincerity and more satisfaction with the relations. The present study was performed by using a descriptive phenomenological qualitative approach with the aim of investigating emotional theory of mind in 19 married Iranian women who were selected by purposive sampling in 2017. In order to coding data, MAXQDA 2018 software and the Colaizzi’s method were used for coding and analyzing the data, respectively. Finally, about three concepts including the emotion type, emotion expression and emotion regulation were extracted from the interviews. Results showed in emotion type, women remarked positive emotions of satisfaction and gratitude and negative emotions of sorrow and sadness only about themselves. Although emotion expression was possible through three ways but in women\u27s view point, men did not react to positive emotion non-verbally. In the third category, coping with negative emotions in the form of going into retreat was raised merely about men and emotion discharge and forgetfulness merely about women. The findings of the present study, a qualitative examination of emotions of the two genders from the viewpoint of women, is to a great extent in line with previous self-report and quantitative studies; they can be applied for Iran and other countries with similar culture and structure

Effects of Laser Irradiation on Caries Prevention

INTRODUCTION: Although dental caries is a preventable disease, it is still common and remains a public health problem. One of the potentially effective preventive measures is the use of lasers. The purpose of this study was to review the studies about use of laser irradiation on the inhibition of carious lesions and the effectiveness of different commercial laser type (Nd:YAG, CO2, and Argon).METHODS: A literature search included journal databases, existing systematic reviews, and studies identified by content experts. Studies meeting inclusion criteria were assessed for quality.RESULTS: Some studies have demonstrated the potential preventive effect of laser irradiation on sound enamel; the effect of irradiation on white spot lesions is still unclear. The effects of irradiating demineralized enamel surfaces coupled with the use of topical fluoride application is also still unclear and further research needs to be conducted in this area. Laser irradiation alone can significantly enhance acid resistance of sound enamel surfaces and prevent caries progression.CONCLUSION: Combined use of topical fluoride application and laser irradiation on sound enamel surfaces has provided the best protection against caries initiation and progression. Laser irradiation was of limited value in managing incipient carious lesions. Argon laser use may be easier clinically due to its large and visible beam diameter, which allows for irradiation of the whole surface of the tooth instead of the overlapping and time consuming pattern of the CO2 laser

Tongue squamous cell carcinoma in a patient with systemic sclerosis: A case report

Objective: Systemic sclerosis (SS) is a chronic autoimmune disease of connective tissue, which involves skin and internal organs, and results in collagen deposition and fibroblasts activation. Studies have reported a higher risk of malignancy in patients with progressive systemic sclerosis (PSS).The aim of this study is to report a case of tongue squamous cell carcinoma (SCC) in a patient with PSS.Case: A 46-year-old woman with SS presented to the Department of Oral Medicine of Shahid Beheshti University of Medical Sciences Dental School with chief complaint of an ulcer on her tongue. During intraoral examination, an asymptomatic ulcer measuring 2.0×1.5 cm was discovered on the right lateral border of the tongue. Incisional biopsy under local anesthesia was performed and histopathological report confirmed presence of squamous cell carcinoma. After further evaluation, surgery was performed, followed by three sessions of brachytherapy and six sessions of chemotherapy. After 26 months of follow-up, there was no evidence of recurrence.Conclusion: Periodic screening examinations are necessary to discover possible malignancies in primary stages in patients with SS

Cognitive Rehabilitation Training in Improving Executive Function, Antisocial Behaviors, and Legal Problems in Children With Attention-Deficit/Hyperactivity Disorder

Background: Attention Deficit Disorder/Attention-Deficit/Hyperactivity Disorder (ADD/ADHD) is one of the most prevalent childhood diseases, and it may substantially influence social behaviors, legal issues, and disputes. The goal was to see how cognitive rehabilitation training affected executive functioning and impulsivity in children with ADHD in Tehran, District 5.Methods: A quasi-experimental design was used, with two groups (experimental and control) and a pretest-posttest. All students with ADHD disorder aged 7 to 12 years were included in the statistical population. The sample comprised 30 kids who were age-matched and randomly split into two groups. They were tested for two months in February and March 2021. Slow cognitive rehabilitation training was given to the experimental group. Both groups were given a pretest and a posttest. Information was gathered using the BRIEF (parent form) and Conners’ (parent form) questionnaires. MANCOVA was used to analyze the data, using the SPSS software v. 26, with a significance threshold of 0.05.Results: There was a significant difference in executive function variables (inhibition, attention transfer, emotional control, initiation, working memory, planning, material organization, and control) and reduced impulsivity (attention deficit , hyperactivity, opposition, and ADHD) (P≤0.001).Conclusion: Cognitive rehabilitation improves executive skills and impulsivity in children with ADHD aged 7-12 years. Cognitive rehabilitation training should be utilized with other educational approaches to rectify social behaviors, minimize conflict, and improve executive functions
