    In compare to Authentication for identification and relationship of an identity of a user with its task and process within the system, authorization in access control is much anxious about confirming that user and its task in the form of system process, access to the assets of any particular domain is only approved when proven obedient to the identified policies. Access control and authorization is always an area of interest for researchers for enhancing security of critical assets from many decades. Our prime focus and interest is in the field of access control model based on Attribute base access control (ABAC) and with this paper we tried to integrate ABAC with openstack cloud for achieving finer level of granularity in access policies for domain like smart grid. Technical advancement of current era demands that critical infrastructure like traditional electrical grid open ups to the modern information and communication technology to get the benefit in terms of efficiency, scalability, accessibility and transparency for better adaptability in real world. Incorporation of ICT with electric grid makes it possible to do greater level of bi-directional interaction among stake holders like customer, generation units, distribution units and administrations and these leads international organization to contribute for standardization of smart grid concepts and technology so that the realization of smart grid becomes reality. Smart grid is a distributed system of very large scale by its nature and needs to integrate available legacy systems with its own security requirements. Cloud computing proven to be most efficient approach for said requirements and we have identified openstack as our cloud platform. We have integrated ABAC approach with default RBAC approach of openstack and provide a frame work that supports and integrate multiple access control polices in making authorization decisions. Smart grid domain in considered as case study which requires support of multiple access policies (RBAC, ABAC or DAC etc) with our model for access control and authorization

    Endometriosis - a widespread disease in women of reproductive age and perimenopausal. Endometriosis is a chronic progressive disease and recurrent disease, which affects 12 to 60% of women of reproductive age. In women with different forms of endometriosis pregnancy occurs according to the latest research with significant abnormalities. According to other authors, 30 - 40% of patients with endometriosis suffer from infertility. Objective. To evaluate the peculiarities of pregnancy, childbirth and the postpartum period in women with endometriosis. Material and methods. In Chernivtsi city maternity hospital №1 were examined 60 pregnant women of reproductive age from 21 to 42 years (average age was 31,5 ± 3,26 years), the main group included 30 women with clinical signs of endometriosis and in control - 30 women without gynecological and somatic disorders. The study of pregnancy in the examined groups showed that in the study group threatened miscarriage occurred 5,9 times more frequently than among patients in the control group. In assessing obstetric complications was found that 76,7% of women with endometriosis, birth complicated by premature rupture of the amniotic membranes, 15% - fetal distress, 8,3% - primary and secondary weakness of labor activity, 3 women was hypotonic bleeding. According Apgar scale the results were better in the control group. Early and late postnatal complications noted the following: uterine bleeding 5% childbirth main group and 1,2% - childbirth control group, subinvolution of uterus in 8,3% and 3,6% respectively. Lohiometra occurred in 30% of patients with endometriosis and 3,6% of patients in the control group. The hospital asked about lactostasis 13,3% childbirth main group and 7,1% in the control group of women in childbirth. Conclusions. 1. Preterm labor occurred 10,4 times more in women with endometriosis than the control group. 2. Labor by Ceserean section was a third of the patients of the main group. 3. Condition of newborns of women with endometriosis were not significantly different from the condition of infants in the control group.Кафедра акушерства та гінекологі

    Lipid peroxide, glutathione and glutathione-dependent enzyme (GST) in mixed zooplankton from the North- West Coast of India: Implication for the use of environmental monitoring

    This work deals with an experiment on mixed zooplanktonic organisms collected from the shore water of Diu coast. The study analyzed and measured lipid peroxidation (LPX), as a marker of oxidative stress and glutathione-s-transferase (GST) activity, as a marker of organic pollution. Both LPX and GST activities were highest at the stations close to the shore and marginally decreased along with transect. The reduced glutathione (GSH) levels were highly variable. The results were discussed in relation to the biomarker application of mixed zooplankton, lipid peroxidation (LPX), glutathione-S-transferase (GST) and reduced glutathione (GSH). The results indicated that, the three potential markers (LPX, GST and GSH), could be used as a measure for bio-monitoring the costal ecosystem using mixed zooplankton as suitable organisms.Key words: Zooplankton, lipid peroxidation, glutathione-S-transferase, reduced glutathione

    Highly-cited estimates of the cumulative incidence and recurrence of vulvovaginal candidiasis are inadequately documented.

    Get PDF
    BACKGROUND: Available literature concerning the epidemiologic or clinical features of vulvovaginal candidiasis commonly reports that: 75% of women will experience an episode of vulvovaginal candidiasis in their lifetimes, 50% of whom will experience at least a second episode, and 5-10% of all women will experience recurrent vulvovaginal candidiasis (≥4 episodes/1 year). In this debate we traced the three commonly cited statistics to their presumed origins. DISCUSSION: It is apparent that these figures were inadequately documented and lacked supporting epidemiologic evidence. Population-based studies are needed to make reliable estimates of the lifetime risk of vulvovaginal candidiasis and the proportion of women who experience recurrent candidiasis. SUMMARY: The extent to which vulvovaginal candidiasis is a source of population-level morbidity remains uncertain

    Glycoprotein IIb/IIIa Inhibitors Use and Outcome after Percutaneous Coronary Intervention for Non-ST Elevation Myocardial Infarction

    Aims. We investigate the effect of glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitors on long-term outcomes following percutaneous coronary intervention (PCI) after non-ST elevation myocardial infarction (NSTEMI). Meta-analyses indicate that these agents are associated with improved short-term outcomes. However, many trials were undertaken before the routine use of P2Y12 inhibitors. Recent studies yield conflicting results and registry data have suggested that GP IIb/IIIa inhibitors may cause more bleeding than what trials indicate. Methods and Results. This retrospective observational study involves 3047 patients receiving dual-antiplatelet therapy who underwent PCI for NSTEMI. Primary outcome was all-cause mortality. Major adverse cardiac events (MACE) were a secondary outcome. Mean follow-up was 4.6 years. Patients treated with GP IIb/IIIa inhibitors were younger with fewer comorbidities. Although the unadjusted Kaplan-Meier analysis suggested that GP IIb/IIIa inhibitor use was associated with improved outcomes, multivariate analysis (including propensity scoring) showed no benefit for either survival (P=0.136) or MACE (P=0.614). GP IIb/IIIa inhibitor use was associated with an increased risk of major bleeding (P=0.021). Conclusion. Although GP IIb/IIIa inhibitor use appeared to improve outcomes after PCI for NSTEMI, patients who received GP IIb/IIIa inhibitors tended to be at lower risk. After multivariate adjustment we observed no improvement in MACE or survival and an increased risk of major bleeding

    Due to the rapid development of the global internetworked infrastructure, the research scope of secure data management has been greatly expanded. Now due to the openness of the internet, databases are accessed by legitimate authorized users as well as the outsiders. So the problems in traditional database security need to be revisited and readdressed in decentralized web-based and open environments. Secure and efficient algorithms are needed that provide the ability to query over encrypted database and allow optimized processing of data. Clearly, there is a compromise between the degree of security provided by encryption and the efficient querying of the database, because the operations of encryption and decryption greatly degrade query performance. We evaluate the performance of the query processing over encrypted database with algorithms REA and with most common algorithms: AES and RC6. The performance of the query over encrypted databases using AES, RC6 and REA algorithms are compared. This performance measure was conducted in terms of query execution time. The experiment results show the advantages of the algorithm REA over other algorithm AES and RC6 in terms of the query execution time. The results show that the encryption algorithm REA outperforms other encryption algorithms at performance and security in databases. The performance of the query enhanced if we encrypt the database by using REA algorithm. So it has achieved security requirements and is fast enough for most applications. REA algorithm is limiting the added time cost for encryption and decryption to do not degrade the performance of a database system. DOI: 10.17762/ijritcc2321-8169.160413
