Information Application for Multicriterial Optimum

The management activity does not only include the techniques and methods of programming, organizing and allocation of resources, starting and control of operations, interventions but it also implies a great number of decisions regarding the launching, carrying on, modifying and carrying out of activities or choosing one of the possible variants so as to ensure that the goals should be reached. The activity of choosing one variant from several possible ones is often met with in maintenance management, such as: the selection of an optimum equipment, the choice of a firm for after/sale service, for supplying materials or spare parts which implies taking into account a large number of factors. The choice based on fundamental mathematic methods becomes feasible by using the current automatic data processing devices and this paper presents the “Xomc” application of establishing the multicriterial optimum.maintenance management, multicriterial optimum, fundamental mathematic methods

Adolescent motherhood and its public health implications

Davila University of Medicine and Pharmacy Romania, Bucuresti The 6th International Medical Congress for Students and Young DoctorsAdolescent pregnancy and parenting are considered social and public health issues. For most of the adolescents, pregnancy and childbirth are neither planned nor wanted. Early motherhood increases the risks for both mothers and their babies. One goal of our study is to evaluate this risk

Impact of Dietary Patterns in Inflammatory Bowel Disease Subtypes Versus Healthy Subjects: a Retrospective Cohort Study.

peer reviewedObjectives:Inflammatory bowel diseases (IBD) have been associated with multiple environmental factors, including diet. A dietary pattern characterized by low fiber content, high fat content and high carbohydrate content has been linked to the development of IBD. The objective of the current investigation is to examine the potential link between dietary patterns and the occurrence of IBD and to investigate whether there are any differences in relation to the type of IBD and specific food groups. Material and methods:We conducted an observational retrospective comparative study using three cohorts: 89 Crohn's disease (CD) patients, 40 ulcerative colitis (UC) patients and 64 healthy subjects. All participants underwent structured interviews and were required to complete a questionnaire regarding their dietary habits either prior to the onset of IBD or within the last year for control subjects. Results:A higher proportion of CD patients reported a higher rate of salt intake (71.9% vs. 53.1%, p-value = 0.043), sweetened beverages (38.2% vs. 17.2%, p-value=0.022), processed meat (66.3% vs. 40.6%, p-value=0.007), fatty meat (50.6% vs. 28.1%, p-value=0.021), fried foods (47.2% vs. 9.4%, p-value<0.001) and mayonnaise (21.3% vs. 6.2%, p-value=0.032) and a lower intake of nuts and seeds (20.2% vs. 43.8%, p-value=0.004) and yogurt (23.6% vs. 43.8%, p-value=0.030) compared to healthy subjects. Compared to controls, in the UC group there was a higher consumption of salt (85% vs. 53.1%, p-value=0.003), sweetened beverages (47.5% vs. 17.2%, p-value=0.005), fatty meat (55% vs. 28.1%, p-value=0.025) and fried foods (55% vs. 9.4%, p-value<0.001) and a lower intake of nuts and seeds (10% vs. 43.8%, p-value=0.001). Conclusion:Diet patterns before the onset of the disease are similar in patients with Crohn's disease and patients with ulcerative colitis: increased consumption of sweetened beverages, processed and fatty meat, fried food, salt, store-bought ice cream, and mayonnaise, and decreased intake of seeds, nuts, and yogurt

The vaccination issue – who is responsible? Retrospective study on 278 infants hospitalized in a pediatric clinical hospital in Bucharest

Carol Davila University of Medicine and Pharmacy, Bucuresti, Romania The 6th International Medical Congress for Students and Young DoctorsVaccines represent one of the most effective and cost-saving public health interventions. Still, this measure continues to be under-used all over the world. Immunization averts an estimated 2 to 3 million deaths every year from diphtheria, tetanus, pertussis (whooping cough), and measles. Although globally the proportion of children who receive recommended vaccines has remained steady for the past few years, we observed during our clinical practice that the vaccination rate in Romania might be lower than the needed vaccination rate. The objective of this study is to test this hypothesis and to highlight the causes of low vaccination rates in Romania

Periodontitis and Heart Disease: Current Perspectives on the Associative Relationships and Preventive Impact

Due to the important advancement and the accumulation of new evidence on the periodontitis-cardiovascular disease (CVD) relationship as well as the major medical, economic and social burden caused by both diseases this chapter aims to review existing epidemiological and pathogenetic links related to this topic. Also, this chapter aims to highlight the impact of the periodontitis-CVD relationships on clinical practice and on the preventive approaches targeting to decrease the impact of periodontitis on CVD. Periodontitis is an infectious disease eliciting local and general inflammation, which leads to periodontal destruction and systemic involvement. Several pathways could explain the link between periodontitis and CVD such as bacteraemia, chronic persistent systemic inflammation and oxidative stress. The first step in the treatment of periodontitis addresses the elimination of microbial components, which lead to a decrease in local and systemic inflammation. Periodontal therapy seems to positively impact CVD. Specialists should inform patients with CVD on the negative impact of periodontitis on their systemic status and refer patients to the periodontist for an extensive examination as routine management of CVD. Some possible risks of periodontal therapy should be considered in patients undergoing antithrombotic medication

Regulation of cellular sterol homeostasis by the oxygen responsive noncoding RNA lincNORS

We hereby provide the initial portrait of lincNORS, a spliced lincRNA generated by the MIR193BHG locus, entirely distinct from the previously described miR-193b-365a tandem. While inducible by low O2 in a variety of cells and associated with hypoxia in vivo, our studies show that lincNORS is subject to multiple regulatory inputs, including estrogen signals. Biochemically, this lincRNA fine-tunes cellular sterol/steroid biosynthesis by repressing the expression of multiple pathway components. Mechanistically, the function of lincNORS requires the presence of RALY, an RNA-binding protein recently found to be implicated in cholesterol homeostasis. We also noticed the proximity between this locus and naturally occurring genetic variations highly significant for sterol/steroid-related phenotypes, in particular the age of sexual maturation. An integrative analysis of these variants provided a more formal link between these phenotypes and lincNORS, further strengthening the case for its biological relevance

Integrating renewable energy sources in marinas and nautical ports in Croatia : an innovative smart grid concept and business plan

Literaturverzeichnis: Blatt 68-78Main objectives of this master thesis are to identify and assess the introduction of renewable energy sources in marinas and nautical ports, jointly with existing environmental programs building on the quality and environmental management and monitoring differentiators and demand estimation tools to achieve competitive advantage. The document explores the current status and drivers of smart grid disruptive technologies, as well as latest technological concepts to propose an integrated solution driving sustainable development towards the achievement of a zero emission marina. With the purpose to address such need, a smart grid concept is proposed integrating a hybrid renewable energy sources distribution system, energy management software and an IOT platform as a turnkey solution. The current scarcity of RES integration in marina operation, as well as increasing favorable market pull and technology push policies, have created an environment fostering innovation with first-mover advantage opportunities. With the emergence of such turn-key solution integrators, the thesis also aims at establishing an efficient methodology for such vehicles to provide a viable venture with a strong emphasis on customer preferred product attributes. Towards the achievement of the proposed objectives the author has decided on international literature review, an electronic audit of official websites of the marina operator electronic survey and business plan for the proposed concept. The results confirm the initial hypotheses and establish in a convincing matter that RES can be integrated into marina operators in line with current environmental programs through a viable smart grid concept. The originality of this master thesis lies in research of recent, international literature on the subject and empirical research performed resulting in the start-up launch proposal of an innovative turn-key solution integrator for marinas and nautical ports in Croatia.10
