Abstract

Purpose

Iron deficiency anemia (IDA) is the most common nutritional anemia in the world and a pervasive health problem, especially in developing countries. Children under two years of age are more prone to be affected by IDA. The best strategy to prevent and treat IDA is to use iron supplements. This study aims to examine the factors associated with noncompliance (such as non-utilization or inconsistent usage) of iron drop supplementation among infants between 6 and 24 months old.

Design/methodology/approach

Online databases (PubMed, Scopus and SID) were searched to retrieve relevant articles published from inception up to July 2023. Among the 2,177 articles detected, after removing duplicate and irrelevant titles, 21 cross-sectional studies that met the authors’ inclusion criteria were included. Screening for articles and data extraction were conducted separately by two researchers.

Findings

The findings suggest that some factors related to mothers, such as education, knowledge, attitude and performance; some factors associated with child such as child’s gastrointestinal and dental complications; taste and smell of iron drops; and birth order and gender are the main determinants of adherence to iron supplementation.

Originality/value

It can be proposed that the most significant factors affecting the feeding of iron drops to children under the age of two include: the level of mother’s awareness, socio-economic status of the household and the occurrence of digestive complications following the supplementation. Given these observations, adopting proper policies toward improving the nutritional awareness of mothers and producing iron supplements with minimal side effects seems crucial.

Abstract

Purpose

The present study aims to design and simulate various types of deoxyribonucleic acid (DNA) origami-based nanopores and explore their stability under different temperatures and constraints. To create DNA origami nanopores, both one-layer and two-layer structures can be utilized.

Design/methodology/approach

One of the key applications of DNA origami structures involves the creation of nanopores, which have garnered significant interest for their diverse applications across multiple scientific disciplines. DNA origami nanopores can be studied individually and in combination with other structures. The structural stability of these nanopores across various temperature conditions is crucial for enabling the passage of diverse payloads.

Findings

Comparing these DNA origami structures can provide valuable insights into the performance of these nanopores under different conditions. The results indicate that two-layer nanopores exhibit better structural stability under various temperatures compared to one-layer nanopores. Additionally, small structural changes in two-layer nanopores enable them to maintain stability even at high temperatures.

Originality/value

In this paper, various DNA origami-based nanopores were designed and simulated, focusing specifically on one-layer and two-layer configurations. The two-layer nanopore consistently exhibited superior stability across both free and restrained scenarios, undergoing fewer structural changes compared to the one-layer nanopore. As temperatures increased, the two-layer nanopore remained less susceptible to deformation, maintaining closer to its original shape. Moreover, in the free scenario, the geometric shape of the two-layer nanopore demonstrated fewer variations than the one-layer nanopore.

Abstract

Purpose

The purpose of this paper is to compare the stability of the three nanocarriers created by DNA origami method with different positions and numbers of crossovers

Design/methodology/approach

Nanocarriers are attractive components among a variety of nanostructures created by DNA origami and can have numerous applications in mechanical and medical engineering. For this reason, the current study compares three nanotubes with different positions and numbers of crossovers created by DNA origami method that can be utilized as nanocarriers. To investigate the structures, the DNA nanocarriers are studied at the human body temperature 310 K. Molecular dynamics simulations are used for this study. For a quantitative analysis of DNA nanocarriers, the areas of three hexagons at three different sites in each of the nanotubes are investigated. The results indicate that the number and position of crossovers are among the significant factors in the structure stability of nanocarriers. The analyses also revealed that although adding crossovers in locations with fewer crossovers increase structural stability, the position of crossovers can have different effects on the stability. DNA origami-based nanocarriers can be implemented in drug delivery, allow the nanocargoes to pass various surfaces and act as filters for passing cargoes of different dimensions and chemical structures.

Findings

The results indicate that the number and position of crossovers are among the significant factors in the structure stability of nanocarriers

Originality/value

In this paper, the stability of DNA origami nanocarriers with different positions and numbers of crossovers was investigated.

Abstract

Purpose

This study aims to investigate the challenges of developing information literacy (IL) competencies and approaches to overcome the challenges among library and information science (LIS) students in Iran.

Design/methodology/approach

Taking an exploratory approach, the study used semi-structured interviews to gather the data. Using the 2000 ACRL standards as a framework, the fieldwork questions were designed around the five areas of IL competencies. A total of 15 academics teaching 18 different LIS courses from six universities were interviewed. They were asked the challenges they faced in teaching these competencies and the approaches they took or suggested in overcoming the challenge(s). A thematic approach was used to analyze the data.

Findings

Some of the challenges for students mentioned by the interviewees were ambiguity about the discipline, inability to match subject relevance with appropriate sources of information and lack of familiarity with databases.

Research limitations/implications

This study is limited to LIS academics; studying students’ reflections can bring broader perspectives to IL education in LIS programs. Owing to the nature of the design of this study, which is a single case study, the teaching experiences of IL are limited to the ones which emerged and were addressed in the context of the case. Although the case selection was made in a way that can be representative of the “general” in the “particular” bounded system of the case (Stake, 1998), studying more cases could certainly have brought broader perspectives to IL which could have been to wider contexts.

Originality/value

The results of this study contribute to our understanding of challenges in teaching IL in the LIS discipline, an area that has not been researched directly. This contributes to IL teaching in disciplinary areas and it brings new perspectives to the elements of IL teaching which emerged from the experiences of people who are directly experienced in the context of the discipline.

Abstract

Purpose

The purpose of this paper is to compare the attitude of the managers of libraries located at Iran, Tehran and Shahid Beheshti Medical Sciences Universities' training hospitals, on the status of information technology (IT) in the mentioned libraries.

Design/methodology/approach

This study employed a researcher‐made questionnaire. The managers of 40 hospital libraries of Iran, Tehran and Shahid Beheshti Universities formed the population of the research. To analyze the collected data, the statistical software SPSS (version 17) was used.

Findings

Results showed that 12.5 per cent of Tehran, 15.6 per cent of Iran and 25 per cent of Shahid Beheshti Universities library managers agreed, to a very large extent, on the application and development of IT and its tools and 93.7 per cent of the managers from all three hospital libraries deemed the application of IT most necessary. The managers believed that the greatest advantage of IT is concerned with the reduction of human efforts (59.4 per cent), and 100 per cent of the managers acknowledged the need for further promotion of their skills in a wide variety of IT issues. In total, 16.1 per cent at Tehran, 12.9 per cent at Iran and 29 per cent at Shahid Beheshti University considerably approved of formal education for the promotion of their librarians' skills.

Originality/value

This study is a step towards acknowledging the contribution, status, and value of hospital libraries to the health sector by the library managers in theory and practice, in the shadow of considering their librarians as network experts, information media and system designers, and technology experts.

Abstract

Purpose

Anxiety disorders have a high prevalence in children. Those children with anxious symptoms are more likely to experience significant disruption in their lives. This disruption can interrupt or even stop a child from participating in a variety of typical childhood experiences. It is understood that genetic and environmental factors may cause this disorder. The purpose of this paper is to focus on environmental factors, namely, the mediating role of maladaptive schemas in mothers’ child-rearing and childhood anxiety disorders.

Design/methodology/approach

This study used correlation-modeling to assess the analysis. The sample included 326 students (aged 9-12 years old) and their mothers. The parenting style (Baumrind, 1973), Early Maladaptive Schema (Rijkeboer and de Boo, 2010), and anxiety disorders (Muris et al., 2006) questionnaires were used in this study.

Findings

The results showed a relationship between parenting styles of mothers and childhood anxiety disorders, a significant correlation between childhood maladaptive schemas and childhood anxiety disorders, a relation between child-rearing styles and childhood maladaptive schemas, and finally a mediating role on childhood anxiety disorders and mothers’ child-rearing styles for some childhood maladaptive schemas.

Originality/value

This research contributes to the knowledge base of the importance of children’s mental health. The paper analyzes the relationship of mothers’ parenting styles and children’s anxiety. It also focuses on maladaptive schemas as a mediator and its relationship with childhood anxiety disorders.
