    (Amer Scientific Publishers, 2020) Ahmadi, Sepideh; Rabiee, Navid; Fatahi, Yousef; Bagherzadeh, Mojtaba; Gachpazan, Meysam; Baheiraei, Nafiseh; Hamblin, Michael R.
    Successful gene therapy depends on the design of effective gene delivery systems. A gene delivery system is considered a powerful tool for the release of genetic material within cells resulting in a change in cell functions and protein production. The release of genes in a controlled manner by using appropriate carriers facilitates their release without side effects and increases the expression of genes at the released site. It is expected that significant changes in the combination of several genes and drugs can be provided by developing treatment systems sensitive to different stimuli such as redox potential, pH variations, temperature gradients, light irradiation, and enzyme activity. The most important advantages for the release of genes and stimuli-responsive therapeutics include delivering vectors locally, reducing side effects and causing no toxicity to distant tissues while at the same time reducing the immune response to the vectors. In this review, we aim to discuss different types of gene carriers involved in the controlled transfer of nucleic acids (non-viral inorganic and organic nanoparticles (NPs) and virus-like particles (VLPs)) as well as the simultaneous transfer of several genes and/or drugs into cells or different tissues, providing for an efficient and safe treatment of numerous diseases.

    Assessing the Coverage of E-Health Services in Sub-Saharan Africa a Systematic Review and Analysis
    (Georg Thieme verlag Kg, 2017) Adeloye, Davies; Adigun, Taiwo; Misra, Sanjay; Omoregbe, Nicholas
    Background: E-Health has attracted growing interests globally. The relative lack of facilities, skills, funds and information on existing e-Health initiatives has affected progress on e-Health in Africa. Objectives: To review publicly available literature on e-Health in sub-Saharan Africa (sSA) towards providing information on existing and ongoing e-Health initiatives in the region. Methods: Searches of relevant literature were conducted on Medline, EMBASE and Global Health, with search dates set from 1990 to 2016. We included studies on e-Health initiatives (prototypes, designs, or completed projects) targeting population groups in sSA. Results: Our search returned 2322 hits, with 26 studies retained. Included studies were conducted in 14 countries across the four sub-regions in sSA (Central, East, South and West) and spreading over a 12-year period, 2002-2014. Six types of e-Health interventions were reported, with 17 studies (65%) based on telemedicine, followed by mHealth with 5 studies (19%). Other e-Health types include expert system, electronic medical records, e-mails, and online health module. Specific medical specialties covered include dermatology (19%), pathology (12%) and radiology (8%). Successes were 'widely reported' (representing 50% overall acceptance or positive feedbacks in a study) in 10 studies (38%). The prominent challenges reported were technical problems, poor inter net and connectivity, participants' selection biases, contextual issues, and lack of funds. Conclusion: E-Health is evolving in sSA, but with poorly published evidence. While we call for more quality research in the region, it is also important that population-wide policies and on-going e-Health initiatives are contextually feasible, acceptable, and sustainable.

    Problems Experienced by the Mothers in Post-Cesarean Period: a Narrative Review
    (Tehran University of Medical Sciences, 2023) Duran,S.; Vural,G.
    Cesarean delivery rates have been increasing which leads to a rise the problems experienced. After cesarean deliveries important problems for the mother and baby may be seen. The most common problems in the mothers after cesarean delivery are; bleeding, infection, fatigue, sleep disorders, breast problems, self-care issues, and sense of inadequacy in care of the newborn. The method used in this study was narrative review. A literature review was conducted by searching the materials published in databases including Web of Science, PubMed, Google Scholar search engine and, the WHO website. Pain, maternal death, breastfeeding problems, worsened sleep quality and comfort, anxiety, delayed recovery, prolonged hospitalization and infection rates in the cesarean deliveries are higher than in vaginal deliveries. Nurses can facilitate adaptation to the role of motherhood and prevent risky situations by evaluating mothers’ care needs and providing proper interventions and support. Nurses should not only focus on the physical care needs of the mother and baby; they should also ensure the physical and psychosocial adaptation of family members in the face of role changes. © 2023 Duran et al.

    A Discussion on Assuring Software Quality in Small and Medium Software Enterprises: an Empirical Investigation;
    (2011) Tolga Pusatli,O.; Misra,S.
    Under the studies of general core activities including software inspection, review and testing to achieve quality objectives in small-medium size enterprises (SMEs), the paper presents a contemporary view of such companies against quality measures. The results from a local empirical investigation of quality standards in the Turkish software industry are reported. Around 150 software companies have been approached from which 17 detailed feedback inform that in order to ensure software quality, standards including internationally recognized International Standards Organization (ISO) and Capability Maturity Model Integration (CMMI) are given credit. However the substantial workload and resources required to obtain them are also reported as serious; downscaled frameworks of such large models proposed in the literature are not well known by the SMEs either. The paper also discusses work around that bypasses such standards to ease delivery of products while keeping certificates as labels just to acquire new jobs for the business.

    Research on Pcb Defect Detection Using Artificial Intelligence: a Systematic Mapping Study
    (Springer Heidelberg, 2024) Ural, Dogan Irmak; Sezen, Arda
    SMT (Surface Mount Technology) has been the backbone of PCB (Printed Circuit Board) production for the last couple of decades. Even though the speed and accuracy of SMT have been drastically improved in the last decade, errors during production are still a very valid problem for the PCB industry. With the exponential rise of Artificial Intelligence in the last decade, the SMT industry was one of the most eager industries to use this new technology to detect possible defects during production. Lately, traditional image processing techniques started to lag behind methods such as machine learning and deep learning when the discussion came to the need of high accuracy. In this paper, we screen academic libraries to understand which of the latest methods and techniques are used in the domain and to deduce a general process for detecting defects in PCBs. During the research we have investigated research questions related to state-of-the-art methods, highly mentioned datasets, and sought after PCB defects. All findings and answers are mapped to be able to understand where this pursuit might point towards. From a total of 270 papers, 90 of them were addressed in detail and 78 papers were chosen for this systematic mapping.

    Software Maintenance Practices Using Agile Methods Towards Cloud Environment: a Systematic Mapping
    (Wiley, 2024) Almashhadani, Mohammed; Mishra, Alok; Yazici, Ali
    Agile methods have emerged to overcome the obstacles of structured methodologies, such as the waterfall, prototype, spiral, and so on. There are studies showing the usefulness of agile approaches in software development. However, studies on Agile maintenance are very limited in number. Regardless of the chosen methodology, software maintenance can be carried out in either a local (on-the-premise) or global (distributed) environment. In a local environment, the software maintenance team is co-located on the same premises, while in a global environment, the team is geographically dispersed from the customer. The main objective of this Systematic Mapping (SM) study is to identify the practices useful for software maintenance using the Agile approaches in the Cloud environment. We have conducted a comprehensive search in well-known digital databases and examined the articles that map to the pre-defined inclusion criteria. The study selected and analyzed 48 articles out of 320 published between 2000 and 2022. The findings of the mapping study reveal that Agile can resolve the major issues faced in traditional software maintenance, making the role of this approach significant in global/distributed software maintenance. Cloud computing plays a vital role in software maintenance. Most of the studies highlight the application of XP- and Scrum-based Agile maintenance models. The study found a need for more Agile maintenance solutions in the cloud, highlighting the importance of agile in software maintenance, both locally and globally. Irrespective of the environment, Cloud computing provides a centralized platform for collaboration and communication, while also offering scalability and flexibility to adapt to diverse infrastructure needs. This allows agile maintenance practices to be implemented across both local and global environments, leveraging the cloud's capabilities to overcome geographical and infrastructural challenges. image

    (Taylor & Francis Ltd, 2020) Arogundade, Oluwasefunmi'Tale; Olotu, Samuel Ibukun; Abayomi-Alli, Olusola; Misra, Sanjay; Ikotun, Abiodun Motunrayo
    Use case has embedded potentials that enable the diversity in its adoption to addressing other issues in software engineering. This objective of this paper is to gathered and classified use case researches carried out over the years and defines the state-of-art. We identified and analysed 62 relevant articles with deep insights into six different initiatives. The publications included 29 journal articles, 18 conference articles, 3 reports, 5 book chapters, 5 workshops and 2 symposiums. This study deduced that as many as 15 different extensions are proposed from use case ranging from formal descriptions to subjective methodology. Use case has evolved from initial functional requirement elicitation to a more formal and extensive structure. There are fewer publications in cloud computing and use case-based systems. This study contributed to the use case body of knowledge by assessing the extended initiatives and giving an overview of the challenges that are not yet resolved.
