  • This paper provides the up to date review of the shading effects on PV module performance and the associated detection algorithm related to the maximum power point tracking. It includes the brief explanations of the MMP variations due to the shading occurrence on the PV modules. Review of experimental and simulation studies highlighting the significant impacts of shading on PV efficiencies were presented. The literature indicates that even the partial shading of a single cell can greatly drop the entire module voltage and power efficiency. The MMP tracking approaches were also reviewed in this study. Both conventional and advanced soft computing methods such as ANN, FLC and EA were described for the proper tracking of MMP under shaded conditions. This paper would be the basic source and the comprehensive information associated with the shading effects and relevant MPP tracking technique.

  • Addressing challenging behavior in young children with special needs is an important issue. This study analyzed the results of literature on parent-implemented behavioral interventions designed to manage the challenging behavior of children with developmental disabilities under 8 years of age. Seventeen relevant studies published in peer-reviewed English journals during the last 15 years were selected for review. The literature review showed that adequately trained parents can serve as a competent intervention agent, thereby making significant contributions to mitigating children's behavior problems. The reviewed studies also demonstrated that parents could play a variety of important roles such as informants and trainers in behavioral interventions. However, the conclusions on parent-implemented behavioral intervention may be tentative rather than conclusive due to previous research limitations including the lack of treatment integrity and social validity data. In addition, this review discussed several implications for practitioners, indicated the limitations of the reviewed studies, and presented suggestions for future research.

  • In order to establish a relationship between sleep related breathing disorder (SBD) and temporomandibular disorders (TMDs), a literature review was performed. A researching was performed based on PubMed, including english languages. Any clinical study identified relationship between SBD and TMD were selected in this review. 13 studies were analyzed in this review. According to SBD diagnosis, articles were grouped as follows: polysomnographic diagnosis (n=7), clinical diagnosis (n=2) and survey/self-report (n=4). 12 articles established a positive relation between SBD and TMD and 1 did not. SBD would be associated with protrusion/retrusion degree, myofascial pain, muscular and joint pathology, and other orofacial findings. It was analyzed that the retrusion of the mandible had the significant influence on the severity of the SBD.

  • A wide literature review on Static Soil-Structure-Interaction (SSI) is done to highlight the key impacts of soil complexity on structural members of framed structures. Attention is paid to the developed approaches, i.e., conventional and Finite Element Method (FEM), to emphasize on deficiencies and merits of the proposed methods according to their applicability, accuracy and power to model and idealization of the superstructures as well as the soil continuum. Proposed hypothesis are much deeply discussed herein for better understanding which is normally neglected in literature review papers due to the large number of references and limit of space.

  • A huge budget is spent on technological solutions to protect Information Systems from cyberattacks by organizations. However, it is not enough to invest alone in technology-based protection and to keep humans out of the cyber loop. Humans are considered the weakest link in cybersecurity chain and most of the time unaware that their actions and behaviors have consequences in cyber space. Therefore, humans' aspects cannot be neglected in cyber security field. In this work we carry out a systematic literature review to identify human factors in cybersecurity. A total of 27 papers were selected to be included in the review, which focuses on the human factors in cyber security. The results show that in total of 14 identified human factors, risk perception, lack of awareness, IT skills and gender are considered critical for organization as for as cyber security is concern. Our results presented a further step in understanding human factors that may cause issues for organizations in cyber space and focusing on the need of a customized and inclusive training and awareness programs.

  • Purpose: This study is an integrative review of previous research conducted on family-school nurse partnership in school health care, as perceived by school nurses, children, and families. Method: The study was conducted according to the five stages of integrative review suggested by Whittemore and Knafl (2005), which involved problem identification, literature search, data evaluation, data analysis, and presentation of results. Suitable literature was found using portals such as PubMed, CINAHL, Embase, and Web of Science. Key words such as school nurses, family, parents, children, and partnership were used to narrow the search results. Studies published in peer-review journals between 2006-2018 were selected. The quality of studies was appraised using critical appraisal tools provided by the Joanna Briggs Institute (2020). Result: Thirteen studies (5 quantitative and 8 qualitative) were finalized for the final review process. After an extensive review, four key themes of school nurse-family partnership in school health care were identified: partnership components, partnership barriers, partnership facilitators, and strategies to promote partnership. Conclusion: Partnership and its components, barriers, and facilitators, along with strategies for its promotion should be considered in school health care. Further studies are needed on the perceptions held by parents and children regarding school health care partnership.

  • Purpose - It is well known that chemyon, referred to by Westerners as face, naturally penetrates the daily life of Asians and influences their cognition, emotion, and behavior. Studies related to chemyon have been conducted in marketing and consumer behavior fields (e.g., luxury products or brands, service failure and recovery, brand preferences, consumer decision making, wedding ceremony, gift giving). A bulk of studies demonstrate that chemyon influences consumption behavior in Asian consumers. Although chemyon significantly influences consumption behavior of Asian consumers, it is also a cultural phenomenon that is not completely explained within the Western viewpoint. Whereas a number of researchers have approached cross-cultural studies of Asian and Western consumers, a limited number of studies have examined it from the perspective of chemyom. The purpose of this study is to compare the phenomenon that chemyon (face) not only affects the consumption behavior of Asia and the West universally (pan-culturally), but also distinctively (culture-specifically). That is, the purpose of this study is to describe that chemyon (face) is not only a culture-specific phenomenon but also a universal phenomenon in the consumption behavior of Asian and Western consumers, even though the extent that chemyon (face) impacts consumption behavior is differentiated. This study aims to understand commonalities and differences between Asian and Western consumption behavior in terms of chemyon (face), and to suggest how to enhance marketing effectiveness in a global market based on understanding the consumption behavior of Asia and the West. Research design, data, and methodology - Using systematic literature review and meta-analysis, this study investigates consumption behavior of Asian and Western consumers from the perspective of chemyon (face). Systematic literature review was used to compare face (chemyon) consumption of Western consumers with that of Asian consumers. To verify systematic literature review, meta-analysis was also accomplished. Results - First, the influence of face (chemyon) on consumption behavior is observed in Western consumers as well as Asian consumers. Second, Asian consumers are more influenced by face (chemyon) than Western consumers. Conclusions - Overall, chemyon (face) can affect the consumption behavior of Asians as well as the consumption behavior of Westerners.
