Targeting Molecular Aberrations in Breast Cancer: Is It about Time?
Authors: Esserman Laura , Benz Christopher , DeMichele Angela 
Published: August 2016

Overview: Breast cancer is not one homogeneous disease; it is a heterogeneous cancer with remarkable genomic variation and variable risk for systemic spread, time to recurrence, and response to treatment. Although it is increasingly clear that a substantial proportion of newly diagnosed patients with breast cancer carry only minimal risk of developing metastatic disease, our inability to accurately prognosticate leads to systemic overtreatment. The recent introduction of multigene predictors for baseline risk assessment and treatment response in breast cancer subsets heralds the beginning of personalized cancer care and the transition to precision medicine. At the same time, rapid clinical adoption of these predictors illustrates the voracious unmet need for better and more finely tuned prognostic and predictive tools. Recent advances in clinical trial designs have enabled the testing of novel agents in combination with standard therapy in the neoadjuvant setting, with a goal of identifying the specific biomarker-drug pairs that should be advanced for confirmatory trials and accelerated approval on the basis of response to therapy.
The FEM Analysis of Stress Distribution in front of the Crack Tip and Fracture Process in the Elements of Modified and Unmodified Cast Steel G17CrMo5-5
Authors: Pała Robert , Dzioba Ihor 
Published: August 2016

Abstract
The article presents influence of modification of the low-alloy cast steel G17CrMo5-5 by rare earth metals on stress distribution in front of the crack at the initial moment of the crack extension. Experimental studies include determination of strength and fracture toughness characteristics for unmodified (UM) and modified (M) cast steel. In the numerical computations, experimentally tested specimens SEN(B) were modelled. The true stress–strain curves for the UM and M cast steel are used in the calculation. The stress distributions in front of the crack were calculated at the initial moment of the crack extension. On the basis of data on the particle size inclusions in the UM and M cast steel, and the calculated stress distributions was performed an assessment of the possibility of the occurrence of cleavage fracture. The analysis results indicate that at room temperature for the UM cast steel, there is a possibility of cleavage fracture, while for the M cast steel occurrence of cleavage fracture is negligible.
Comparative Evaluation of the Different Data Mining Techniques Used for the Medical Database
Authors: Kasperczuk Anna , Dardzińska Agnieszka 
Published: August 2016

Abstract
Data mining is the upcoming research area to solve various problems. Classification and finding association are two main steps in the field of data mining. In this paper, we use three classification algorithms: J48 (an open source Java implementation of C4.5 algorithm), Multilayer Perceptron - MLP (a modification of the standard linear perceptron) and Naïve Bayes (based on Bayes rule and a set of conditional independence assumptions) of the Weka interface. These classifiers have been used to choose the best algorithm based on the conditions of the voice disorders database. To find association rules over transactional medical database first we use apriori algorithm for frequent item set mining. These two initial steps of analysis will help to create the medical knowledgebase. The ultimate goal is to build a model, which can improve the way to read and interpret the existing data in medical database and future data as well.
Observations of MR Fluid Clumping Behaviour in a Squeeze-Mode Damper
Authors: Sapiński Bogdan 
Published: August 2016

Abstract
The study summarises the results of quasistatic experimental tests of an MR squeeze-mode damper prototype (MRSQD) performed at the MTS testing machine. Of particular interests was the influence of MR fluid clumping behaviour in the MRSQD working gap on the force output of the device. The MRSQD tests were assessed by measuring the damping force output at prescribed sinusoidal displacement inputs and at various (fixed) voltage levels resulting in the respective average current levels in the control coil. The influence of piston position offset on the damping force was also investigated. The collected data were shown in the form of damping force time histories and damping force-piston displacements loops and discussed with respect to MR fluid clumping behaviour.
Oxy-combustion of biomass in a circulating fluidized bed
Authors: Kosowska-Golachowska Monika , Kijo-Kleczkowska Agnieszka , Luckos Adam , Wolski Krzysztof , Musiał Tomasz 
Published: August 2016

Abstract
The objective of this study was to investigate combustion characteristics of biomass (willow, Salix viminalis) burnt in air and O2/CO2 mixtures in a circulating fluidized bed (CFB). Air and oxy-combustion characteristics of wooden biomass in CFB were supplemented by the thermogravimetric and differential thermal analyses (TGA/DTA). The results of conducted CFB and TGA tests show that the composition of the oxidizing atmosphere strongly influences the combustion process of biomass fuels. Replacing N2 in the combustion environment by CO2 caused slight delay (higher ignition temperature and lower maximum mass loss rate) in the combustion of wooden biomass. The combustion process in O2/CO2 mixtures at 30% and 40% O2 is faster and shorter than that at lower O2 concentrations.

Authors: Dirik Süleyman , Atçeken Mehmet 
Published: August 2016

Abstract
In this paper, we study the geometry of the pseudo-slant submanifolds of a cosymplectic space form. Necessary and sufficient conditions are given for a submanifold to be a pseudo-slant submanifold, pseudo-slant product, mixed geodesic and totally geodesic in cosymplectic manifolds. Finally, we give some results for totally umbilical pseudo-slant submanifold in a cosymplectic manifold and cosymplectic space form.

The time-varying shortest path problem with fuzzy transit costs and speedup
Authors: Rezapour Hassan , Shirdel Gholamhassan 
Published: August 2016

Abstract
In this paper, we focus on the time-varying shortest path problem, where the transit costs are fuzzy numbers. Moreover, we consider this problem in which the transit time can be shortened at a fuzzy speedup cost. Speedup may also be a better decision to find the shortest path from a source vertex to a specified vertex.

Authors: Cuculeski Nikola , Petrovska Ilijana , Cuculeski Vasko 
Published: August 2016

Abstract
Nowadays, the sustainability plays an important role in developing marketing in tourism, both from the theoretical and from the practical aspect. Sustainable marketing considers the general principles of marketing, with respect to sustainability as a new focus for a long-lasting customer relationship. Therefore, the business marketing in tourism should consider the importance of perceptions and expectations of tourists as final consumers. Regarding different marketing elements with sustainable aspect, this paper aims at investigating consumers’ perceptions of foreign tourists in Republic of Macedonia. In order to provide tourist perceptions and expectations, a survey based research was conducted among 254 foreign tourists in four cities in Republic of Macedonia, concerning aspects as: tourist perceptions of marketing elements of the current tourist offering and their expectations towards sustainable tourism development. For this purpose, statistical methods have been used as: Hi2-test, Student’s t-tests as well as correlation and Anova, using a specific program STAT FOR WINDOWS and STATA 11 for descriptive statistics of demographic characteristics of the sample.
The paper presents the main findings from the literature, drawing conclusions from the empirical research and providing recommendations for future academic and business research. Considering the specifics of different target segments, results from this research are presenting the need for lower pricing, increased promotional activities using social media, providing online booking and development of ecotourism.

Abstract

Introduction:
The changes in the eating habits associated with physical inactivity are directly related to the increase in the prevalence of obesity and associated diseases such as diabetes mellitus (DM), metabolic syndrome and cardiovascular diseases.

Objective:
The aim of this study was to investigate the relationship between the frequency of consumption of some food groups (snacks, fruits, vegetables and candies), physical exercise, nutritional classification and biochemical profile in children.

Methods:
After the approval of the Ethics Committee, we studied 882 schoolchildren ranging between 6 and 10 years of age. Biochemical and anthropometric evaluations were performed and questionnaires were used in order to check the eating habits and physical activity.

Results:
Our results showed that we may relate the consumption of snacks, fruits, vegetables or candies with modifications in the glycemia, triglycerides, total cholesterol, HDL-c, and LDL-c but we did not observe association with the nutritional classification. It is noteworthy to say that almost 50% of the studied children were overweight or obese and many presented alterations in the lipid and glucose levels.

Conclusion:
Our results also show that many children have abnormal levels of lipids and glycemia and a great number of them are classified as overweight or obese. In this context, we can say that urgent approaches are needed to be carried out by a multidisciplinary team in order to improve the diet and reduces the risk factors in this population of children and prevent secondary diseases in adolescence and adulthood.
Learning from childhood: children tell us who they are through online dialogical interaction
Authors: Saracco Susanna 
Published: August 2016

Abstract
Philosophy of childhood is a field of inquiry in which the protagonists are adults, who are trying to understand children, and children, who are trying to be understood by adults. These two operating agents must find a common ground that renders their communication possible. This piece develops and illustrates the notion that no theorisation can exist if the authors of the theories do not know the subjects of their study, and thus that philosophers of childhood cannot contribute to knowledge about childhood unless they create occasions for the voices of children to be heard. Therefore, when activities are devised for the free expression of childhood, they cannot meaningfully be categorised as separate from philosophy of childhood. The latter cannot exist without the former. Philosophy of childhood and philosophy for children are interlaced in their work with children. Once the nature of childhood is understood through what children tell about themselves, instead of narrated through the interpretive frameworks of adults, the rights of the children can be effectively protected.
“What’s the Big Deal to Be Romanian if You Don’t Have What to Eat” : Food Practices in “Transition”
Authors: Alexandra Ciocănel 
Published: August 2016

AbstractThis article examines some of the main changes in food practices from the first half of 1990s shaped by the new political and economic environment. Based mainly on an analysis of press articles from this period, three main themes are identified in the discussion of alimentation: “hunger”, queues, and new configurations of commerce. This article suggests that these are entangled in a changing culture of shortages specific to the 1980s through an adaptation of older practices of consumption and commercialization of food, discursive tropes and moral judgments. In this way, a simultaneously prospective and retrospective orientation appears in which some of the ethos of the previous social order is used in new ways of making sense of the present. Food plays an important role in this orientation, its rationalization and precariousness specific to the 1980s being now replaced by new worries and uncertainties raised by the economic measures of “transition”.
The Diagnosis and Hemodynamic Monitoring of Circulatory Shock: Current and Future Trends
Authors: Hendy Adham , Bubenek-Turconi Şerban-Ion 
Published: August 2016

Abstract
Circulatory shock is a complex clinical syndrome encompassing a group of conditions that can arise from different etiologies and presented by several different hemodynamic patterns. If not corrected, cell dysfunction, irreversible multiple organ insufficiency, and death may occur. The four basic types of shock, hypovolemic, cardiogenic, obstructive and distributive, have features similar to that of hemodynamic shock. It is therefore essential, when monitoring hemodynamic shock, to making accurate clinical assessments which will guide and dictate appropriate management therapy. The European Society of Intensive Care has recently made recommendations for monitoring hemodynamic shock. The present paper discusses the issues raised in the new statements, including individualization of blood pressure targets, prediction of fluid responsiveness, and the use of echocardiography as the first means during the initial evaluation of circulatory shock. Also, the place of more invasive hemodynamic monitoring techniques and future trends in hemodynamic and metabolic monitoring in circulatory shock, will be debated.

Forms of Social Conflicts in Schoolchildren as Perceived by the Children’s Teachers
Authors: Stránská Zdenka , Poledňová Ivana , Koběrská Tereza 
Published: August 2016

Abstract
Our article deals with social conflicts in “troubled” schoolchildren from the perspective of their teachers. Using Behaviour Assessment System for Children – Teacher Rating Scale (Czech method), a total of 92 schoolchildren have been tested. All the children were identified by their teachers as having behavioural difficulties. The children with behavioural difficulties have been found to engage especially in peer-related social conflicts, which involved negative relationships with classmates and aggressive behaviour, particularly in the younger children (1st to 5th grade of compulsory education). The relevant personality traits included a higher tendency to lie, higher levels of emotional reactivity, and a negative attitude towards one’s own behaviour. Based on the results, a recommendation is given to teachers working with children with behavioural difficulties, to aid prevention and render psychological counselling.
The driving force of action and the psychology of doing nothing
Authors: Bańka Augustyn 
Published: August 2016

Abstract
My article discusses the psychological factors determining the driving force of human activity as well as the driving force of doing nothing. The discussion is related to the personal resources characteristics (personality, the type of mind, operational style), personal coping strategies with the pressures of time (procrastination, indecisiveness), an autonomous vs. non-autonomous reality creating style (passion, passivity), and anticipatory identity capital modelling by capitalizing on one’s own advantages and proactivity. The driving force of human activity and doing nothing presented in the article is discussed from a psychological perspective as a multidimensional phenomenon. Firstly, it is discussed as a preconditioned personality trait, secondly as a contextually determined search for exiting from a difficult situation by delaying a decision, thirdly as an agentural creation of energy program of action (passion, apathy), and at the end as an agentural production of the self-advantages through proactivity. My article also reviews basic types of discontinuity and personality types related to them. These five discontinuity types are: 1 – place discontinuity, 2 – situation discontinuity, 3 – meanings and values discontinuity, 4 – context discontinuity, 5 – projective discontinuity.
Multiwork, work-family/family-work conflict and satisfaction with life
Authors: Lipińska-Grobelny Agnieszka 
Published: August 2016

Abstract
The aim of my study was to determine what relations exist between work and family demands, W-F/F-W conflict and job satisfaction, satisfaction with marriage, and life satisfaction among multiworkers and monoworkers. Research involved 218 multiworkers and 218 employees with single employment, who filled out a survey, the Organizational Climate Questionnaire, the W-F/F-W Conflict Technique, the Job Description Questionnaire, the Marital Communication Questionnaire, and Satisfaction with Life Scale. From the data obtained referring to multiworkers, it is shown that W-F conflict is directly affected by the number of working hours, commuting time, job demands, rewards, and leave control. F-W conflict is directly affected by number of children aged up to six years, partner engagement, and the number of children aged 12‒15 years. Satisfaction with life results from satisfaction with marriage and job satisfaction (stronger relationship). Considering the monoworkers, W-F conflict is directly affected by the number of working hours, commuting time, and the rewards at work. F-W conflict is directly affected by engagement of the partner and the depreciation in the relationship. Satisfaction with life results from satisfaction with marriage (stronger relation) and job satisfaction. These results contribute to deeper knowledge on the multiwork phenomenon.
Impact of Water on Rheological Behavior of Polyurethane Glues
Authors: Laiveniece Laura , Morozovs Andris 
Published: August 2016

Abstract
Gluing of wood with great moisture content has challenge of water interaction with glue to give unwanted changes in glue properties and formed bond-line. Rheological measurements of polyurethane glues are sufficiently effective method to understand the polymer curing process and viscoelastic properties. Gel formation point is important parameter for a glue from the point of its application. When glue reaches the gel formation point, its viscosity drastically increases so that it could not properly wet the wood and it can result in poor bonds. One-component moisture curing polyurethane glues require water molecules for the polyadditional reaction. When water is involved in the curing reaction, it reacts with the isocyanate groups of glue and can lead to the formation of excessive carbon dioxide and thus can lead to glue penetration out of bond-line, additional backpressure. The dynamic viscoelastic parameters such as complex dynamic viscosity (ή), phase angle (δ), elastic storage modulus (G”), the viscous loss modulus (G”) of two kinds of polyurethane glues depending on added water amount (from 0.9% to 10.0%) at a constant frequency and deformation (oscillation mode) were determined using rheometer. The aim of the present study was to investigate impact of added water on rheological behavior of polyurethane glues. At the end of this study it was concluded that tested glues indicated various behavior depending on chemical composition and added water content. Gel formation point is higher in case of GlueI. However, gel formation time was higher in case of GlueII and was not dependent on added water content. Gel formation time was faster for GlueII. Nevertheless, faster formed gel is stronger than longer formed gel of GlueI.
