Volume 9, Issue 3 (9-2015)
Abstract

Background and Aim: The use of probiotics has been surveyed in different studies. For example, many researches have been conducted on immunity, cancer and embryonic cells proliferation. Mesenchymal stem cells (MSCs) have a rather slower growth and a more limited number of passages. In this research, the effect of supernatant of Lactobacillus acidophilus (LS) as one of the most commonly used probiotics on the proliferation of mesenchymal stem cells has been studied with the aim of increasing their proliferation for the treatment of patients in need of transplantation using mesenchymal stem cells.

Materials and Methods: The MSCs separated from rats’ bone marrow were led to bone and fat levels in the second passage, and their mesenchymal state was confirmed. The cells were then treated by the supernatant of Lactobacillus acidophilus (LS) and MRS broth medium, which have been separated in advance. The number of cells was examined by MTT test equated with the standard.

Results: A curve was drawn for the cells’ growth in different amounts and the number of cells was obtained by converting the results of MTT test to a standard curve. For statistical analyses, SPSS and ANOVA were employed.

Conclusion: The findings show the double effect of LS on the weak effect of MRS broth medium. The use of supernatant of Lactobacillus acidophilus (LS) can be a practical and economical method for increasing the proliferation of MSCs isolated from bone marrow.

Abstract
Background and Aim: Nowadays, the application of Information and Communication Technology is becoming increasingly prevalent in our daily lives, and especially in organizations. One of these phenomena is employees' use of the organization's Internet for personal purposes during work hours, which is referred to as cyberloafing. One of the important organizational variables that can strongly be influenced by this technology is the level of entrepreneurship in the organization. Therefore, this study seeks to investigate the relationship between cyberloafing and organizational entrepreneurship(OE) in Babolsar Healthcare and Treatment Network(HTN).
Materials and Methods: The present research is an applied study. The statistical population of the study includes all employees of Babolsar HTN. Using simple random sampling, 165 employees were selected as sample. In this study, standard questionnaires were used to measure cyberloafing and OE. Finally, the data were analyzed by using SPSS and LISREL softwares.
Results: The findings of this study showed that there was a significant and inverse relationship between OE and cyberloafing(P<0/001). There was also a significant inverse correlation between organizational entrepreneurship and cyberloafing in structural equation modeling test. On the other hand, the values of the fit indices were RMSEA=0.022, NFI=0.96, GFI=0.97 and χ2/df=1.07, that all indicate the suitability of the model.
Conclusion: The results of this study indicated that cyberloafing phenomenon in Babolsar HTN had an adverse effect on OE. Based on these results, it is suggested that HTN managers teach their employees how to use cyperloafing effectively.

Malihe Ghanaatjoo, Nader Jahanmehr, Dr. Hamed Dehnavi, Aida Samadi,
Volume 18, Issue 2 (5-2024)
Abstract
Background and Aim: The increase in the amount of information and the need for their daily monitoring have led to the development of tools called management dashboards that have the ability to analyze graphical data. In addition to preparing quick reports in different time frames and user-specific format, the dashboard can be useful for providing dynamic updated information for accurate decision-making and quick response to changes.
Materials and Methods: The current research was carried out in the form of qualitative studies and participatory action research method in 9 steps. In this applied and developmental research that was conducted cross-sectionally using the data of the first half of 2022, 11 members of the leadership team of a super-specialized children’s hospital were selected as research participants. The data collection tool was an interview using a questionnaire to determine the importance of indicators and a usability questionnaire (usability) of the dashboard based on three independent variables (usefulness, ease of use and satisfaction). The Excel file of data needed for the dashboard was collected from the HIS system of the hospital, and the dashboard was designed with Power BI software, and the capabilities and access levels of users were determined based on their duties. Data analysis was done using descriptive statistics and Excel software version 2016.
Results: In the stage of determining key performance indicators, out of 39 indicators selected by the research team, 22 indicators scored an average score of 4 or higher (from 5 points) and 21 indicators were able to be implemented. The data repository in Excel format was used as an intermediate environment. The dashboard was displayed on six pages (indicators related to the performance of inpatient beds, mortality, emergency and other indicators) and the capabilities of each page were determined. After implementing the dashboard and determining the access levels of users, obtaining a high score from the questions of the usability questionnaire (5 out of 7 points) and obtaining an average score of 71.8 out of 5 questions related to usefulness variables, 70.5 out of 8 questions related to ease of use. And 71 out of 3 questions related to the satisfaction variable showed that the dashboard designed for the hospital had high usability.
Conclusion: Hospital management dashboard information can be a basis for informed decision-making to achieve benefits such as identifying the best performance, improving performance quality, making faster decisions, reducing errors, improving capacity management and work flow, allocating resources and planning for growth and development.
