- چکیده انگلیسی: Background: Game-based instruction is one of the methods that encourage exploration among learners. Identifying and incorporating exploratory components should be considered as a principal goal in designing a game that provides exploratory instruction. The present study aims to investigate the exploratory components of an educational game. Methods: A systematic review of the literature was performed in accordance with PRISMA guidelines. Based on the inclusion criteria, a comprehensive search was conducted in Google Scholar, ProQuest, ScienceDirect and Scopus for articles published between 1995-2019. A combination of keywords were used in the search, including ("educational game" OR "serious game" OR "adaptive game") AND ("player type" OR "player style" OR "player modeling" OR "Bartle player style" OR "explorer player"). A manual search was also conducted in Google to identify more literature. Furthermore, out of 1034 articles, 39 were studied in depth. Results: The obtained components were categorized in six sections, including: educational elements (research, serious game, projectbased activities, test hypotheses, question and answer, role play, simulation), exploratory dynamics (exploration, solving, collecting, and build), mechanics (chance, conflict or challenge, collaboration [negative relationship], prizes upon completion, non-linear space, existence of creative tools, existence of ancillary equipment, guidance, open content, customizability, access to all facilities, different ways to study elements and environment, and puzzle), aesthetics, branch stories and proportionality, exploration-based games (emphasis on the pivotal challenge to success, emphasis on meaningful choices, emphasis on thinking versus physical work, emphasis on longer game sessions, no punishment, emphasis on freedom versus control, emphasis on details versus imagination). Conclusion: Designers can draw on these components when developing a game that suits the learners’ styles. Analysis of the studies showed that the obtained components could be used in educational game design, and the obtained framework is a useful guide for game designers.

- چکیده:
- چکیده انگلیسی: Treatment of landfill leachate is challenging, due to its characteristics such as age, dumping place, composition and origin of wastes. For this reason, the application of hybrid processes is helpful for complete treatment of contaminants present in the leachates. The addition of membrane operations to biological treatment technology offers new advantages for this method. For this aim, a bench-scale integrated process based on submerged aerobic MBR has been designed and fabricated. Also, Nanofiltration process as a post-treatment was used to upgrade MBR effluent. The results showed that the submerged UF-MBR system effectively removed biodegradable trace organic compounds with the average removal rate of about 75% at optimum food-to- microorganism (F/M) ratio (BOD basis) of 0.2 gBOD/g.d under a HRT of 24 h. The addition of NF process increased the treatment efficiency up to 98%. The effluent COD was reduced from 3500 mg/l to below 50 mg/l. Further, the effect of PAC addition was studied. NH3 –N, TKN and Heavy metals removal efficiency were obtained 97 ± 2%, 96 ± 2% and 99 ± 2%, respectively.

- چکیده:
- چکیده انگلیسی: The majority of diseases caused by air pollution, such as asthma and allergies, are caused by pathogenic bacteria, which are transmitted through bioaerosols. Bacteria and fungi are the main sources of hospital infections causing the majority of diseases and cases of mortality. The aim of this study was to determine the ratio of indoor to outdoor fungi concentration, the effect of population density on fungi concentration, and the relationship between indoor and outdoor environments. In this study, 3 stations were assessed; the outdoor environment, general indoor environment, and intensive care units (ICUs) of a hospital affiliated to Ahvaz University of Medical Sciences, Iran. These stations were used for the sampling of airborne fungi from October to December 2010. The samples were collected over a period of 2 minutes in a flow rate of 28.3 l/minute using a QuickTake 30 air sampling pump. The 3 dominant fungi genera in the sampling stations were Aspergillus, Penicillium, and Cladosporium. The average of total fungi concentration before visiting hours was 365.8 CFU/m which was reduced to 578 CFU/m after visiting hours. The indoor to outdoor ratios in the ICU and internal wards for fungi before visiting hours were 0.36 and 0.68, respectively. However, these ratios in the ICU and internal wards for fungi after visiting hours were 0.78 and 0.99, respectively. Following the visiting hours, the concentration of fungi available indoors was conspicuously higher (even in the wards in which no visitors were allowed (e.g., ICUs). Hence, the amount of indoor fungi was affected by the concentration of outdoor fungi and the number of visitors.

- چکیده:
- چکیده انگلیسی: The intensity of competition in business markets is to the extent that even the slightest strategic mistakes will lead to the failure of the organizations. The lack of knowledge and implementation of appropriate competitive strategies in such markets and, on the other hand, the failure to review the effects of these strategies on the types of cash flows in diverse capital structures is no also an exception to this rule. The subject of this study is to design and explain the affectivity model of types of cash flows in a diversified capital structure based on the type of strategy. The present study is an applied one in terms of objective, a quantitative one in terms of data type and a descriptive survey one regarding how to conduct. The statistical population consisted of all companies listed on the Tehran Stock Exchange during 2013 to 2017, among which 139 companies were selected as the sample by systematic elimination method. The statistical method used is the panel data method and fitting the regression models has been conducted using the same data. The results indicated that there is no significant difference between the effect of the differentiation strategy on the cash flow of accounting and cash flows to equity in companies that have a debt-based capital structure with companies whose capital structure is based on equity.
