Efficient Business Intelligence systems utilization : Deliberation of information quality significance on decision-making

Business Intelligence (BI) system facilitates informed and timely decision making incompetitive business environment. However, decision making can turn out to be highlychallenging if information delivered by BI system does not meet certain level of quality.Organization can benefit from provided information if they are correct, comprehensive,current, and accessible. The organizational members who use BI application to make decisionare best informants to verify the quality of delivered information. Additionally,the implementers of BI system are the one who must be aware of delivering high qualityof information and can explain the reason of failures if any. It is critical to inquire bothimplementers and users. Therefore, the factors that can affect the quality of informationwere studied through comprehensive literature review. Low quality of information maymake customers/ suppliers’ relationship worse, shrink the efficiency of the business performance,decrease the level of trust on BI, and eventually cause to lose the competitivenessin market place. This thesis is intended at investigating fundamental dimensionsthat hinder effective utilization of information in BI system and realizing how these dimensionscan affect the quality and outcome of decisions. Study with an exploratorypurpose was designed and conducted at a chain retail stores in Iran to gather empiricaldata from both group of BI users and implementers through focus group interview. Theresult of investigation shows the main BI system utilized to facilitate customer/ supplierrelationship management and store operation management. Business areas and activitiesinfluenced by the quality of information include, inventory management, customer loyalty,competitiveness, and supplier management. The information quality issues are encounteredmainly due to technical failures, lack of competent system developers, changesin business environment, inappropriate documentation during the system developmentlifecycle, and logical error in programming and designing algorithms. The time, effort,and resources spent on exploring and resolving problems regarding to the quality of informationhad a great influence on efficiency and effectiveness. Documentation duringsystem development life cycle is emphasized as a crucial factor that necessitates furtherstudy in documentation subject. The preliminary findings signify the importance of study to consider information quality in BI practice

Antifungal Effects of <i>Zataria multiflora</i> Essential Oil on the Inhibitory Growth of some Postharvest Pathogenic Fungi

The present study aimed to determine minimum inhibitory concentration and minimum fungicidal concentration of the essential oil of Zataria multiflora to control Alternaria solani, Rhizoctonia solani, Rhizopus stolonifer, Aspergillus flavus, Aspergillus ochraceus and Aspergillus niger. The essential oil of Zataria multiflora was tested in vitro on PDA (malt extract agar medium) with eight concentrations: 0, 10, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900 and 1000 ppm. This investigation followed the completely randomized design (CRD) with three replications. GC-MS evaluations of the essential oil revealed that thymol (35%), carvacrol (34%), cymene-p (9.89%), gamma-terpinene (5.88%) and alpha-pinene (4.22%) were the main compounds of Zataria multiflora oil. The results showed that the essential oil of Zataria multiflora has antifungal activity; the lowest inhibition (75%) was observed in the A. niger, while the highest inhibition (95.3%) was observed in A. solani. Minimum inhibitory concentration for A. solani, R. solani, R. stolonifer, A. flavus, A. ochraceus and A. niger was 200, 200, 200, 300, 300 and 200 ppm respectively. In addition, the present results showed that minimum fungicidal concentration (MFC) for A. solani, R. solani, R .stolonifer, A. niger and A.ochraceus was 600, 400, 300, 900 and 700 ppm respectively and none of the tested concentrations were fatal for A. flavus. A. solani and R. solani showed a strong sensitivity to Zataria multiflora essential oil at all concentrations. Findings of the current study suggest that essential oils of Zataria multiflora could be used for control of postharvest phytopathogenic fungi on fruits or vegetables

Antifungal activity of Zataria multiflora essential oil-loaded solid lipid nanoparticles in-vitro condition

Objective(s): The aim of the present study was to prepare, characterize, and evaluate solid lipid nanoparticles (SLNs) containing Zataria multiflora essential oil (ZEO). Materials and Methods: In this study, Z. multiflora essential oil-loaded solid lipid nanoparticles (ZE-SLNs) were prepared to improve its efficiency in controlling some fungal pathogens. SLNs containing Z. multiflora essential oil were prepared by high shear homogenization and ultra sound technique. ZEO-SLNs contained 0.03% ZEO in 5% of lipid phase (Glyceryl monostearate-GMS and Precirol® ATO 5).Tween 80 and Poloxamer 188 (2.5% w/v) were used as surfactant in the aqueous phase. The antifungal efficacy of ZE-SLNs and ZEO was compared under in vitro conditions. Results:The particle size of ZE-SLNs was around 255.5±3 nm with PDI of 0.369±0.05 and zeta potential was about -37.8±0.8 mV. Encapsulation efficacy of ZE-SLNs in crystalline form was 84±0.92%. The results showed that the ZEO and ZE-SLNs had 54 and 79% inhibition on the growth of fungal pathogens, respectively. The minimum inhibitory concentration (MIC) under in vitro conditions for the ZEO on the fungal pathogens of Aspergillus ochraceus, Aspergillus niger, Aspergillus flavus, Alternaria solani, Rhizoctonia solani, and Rhizopus stolonifer was 300, 200, 300, 200, 200 and 200 ppm, respectively, for ZE-SLNs, it was 200, 200, 200, 100, 50 and 50 ppm. The antifungal efficacy of ZE-SLNs was significantly more than ZEO. Conclusion: Our results showed that the SLNs were suitable carriers for Z. multiflora essential oil in controlling the fungal pathogens and merits further investigation

Tehran environmental and neurodevelopmental disorders (TEND) cohort study : Phase I, feasibility assessment

Purpose: To advance knowledge about childhood neurodevelopmental disorders and study their environmental determinants, we conducted a study in Tehran, Iran to assess the feasibility of prospective birth cohort study. Methods: We evaluated participation of pregnant women, feasibility of sampling biological material, and health care services availability in Tehran in four steps: (1) first trimester of pregnancy; (2) third trimester of pregnancy; (3) at delivery; and (4) two to three months after delivery. We collected related data through questionnaires, also various biological samples were obtained from mothers (blood, urine, milk and nails—hands and feet) and newborns (umbilical cord blood, meconium, and urine samples) from February 2016 to October 2017. Results: overall 838 eligible pregnant women were approached. The participation rate was 206(25%) in our study and about 185(90%) of subjects were recruited in hospitals. Out of 206 participants in the first trimester, blood, urine, hand nail, and foot nail samples were collected from 206(100%),193(93%), 205(99%), and 205(99%), respectively. These values dropped to 65(54%), 83(69%), 84(70%), and 84(70%) for the remaining participants 120(58%) in the third trimester, respectively. Also, we gathered milk samples from 125(60%) of mothers at two to three months after delivery. Conclusion: Our findings suggest that hospitals were better places for recruitment of subjects in a birth cohort in Tehran. We further concluded that birth cohort study recruitment can be improved by choosing appropriate gestational ages. Obtaining the newborn’s urine, meconium, and umbilical cord blood were challenging procedures and require good collaboration between hospital staff and researchers.</p
