Authors: Musial Jedrzej , Lopez-Loces Mario C. 
Published: July 2017

Abstract
Internet shopping is one of the main pillars of electronic commerce.According to the literature, the Internet Shopping Optimization Problem (ISOP)has been defined in order to optimize the global cost of online purchase, taking into account both the cost of products and shipping. In this study, it was decided to propose and analyze a very interesting, and really substantial, extension of the ISOP.Namely, trust factors were subjected to careful analysis from the customer point of view. The analysis is based on a specially prepared questionnaire, supplemented by the information from the literature and our own observations. Thus, it was possible to propose a definition of a new mathematical model of the problem, and to prove its affiliation to the class of strongly NP-hard problems. In addition, the heuristic algorithm is proposed, which can be used to solve the problem.

Applied algorithms for face detection are described and achieved results of face detection in the real bank environment conditions are presented. Practical limitations of the application based on encountered problems are discussed.
The Econometric Procedures of Specific Transaction Identification
Authors: Doszyń Mariusz , Gnat Sebastian , Bas Marcin 
Published: July 2017

Abstract
The paper presents the econometric procedures of identifying specific transactions, in which atypical conditions or attributes may occur. These procedures are based on studentized and predictive residuals of the accordingly specified econometric models. The dependent variable is a unit transactional price, and explanatory variables are both the real properties’ attributes and accordingly defined artificial binary variables. The utility of the proposed method has been verified by means of a real market data base. The proposed procedures can be helpful during the property valuation process, making it possible to reject real properties that are specific (both from the point of view of the transaction conditions and the properties’ attributes) and, consequently, to select an appropriate set of similar attributes that are essential for the valuation process.

Effect of cationic polyelectrolytes in contact-active antibacterial layer-by-layer functionalization
Authors: Chen Chao , Illergård Josefin , Wågberg Lars , Ek Monica 
Published: July 2017

Abstract
Contact-active surfaces have been created by means of the layer-by-layer (LbL) modification technique, which is based on previous observations that cellulose fibers treated with polyelectrolyte multilayers with polyvinylamine (PVAm) are perfectly protected against bacteria. Several different cationic polyelectrolytes were applied, including PVAm, two different poly(diallyl dimethyl ammonium chloride) polymers and two different poly(allylamine hydrochloride) polymers. The polyelectrolytes were self-organized in one or three layers on cellulosic fibers in combination with polyacrylic acid by the LbL method, and their antibacterial activities were evaluated. The modified cellulose fibers showed remarkable bacterial removal activities and inhibited bacterial growth. It was shown that the interaction between bacteria and modified fibers is not merely a charge interaction because a certain degree of bacterial cell deformation was observed on the modified fiber surfaces. Charge properties of the modified fibers were determined based on polyelectrolyte titration and zeta potential measurements, and a correlation between high charge density and antibacterial efficiency was observed for the PVAm and PDADMAC samples. It was demonstrated that it is possible to achieve antibacterial effects by the surface modification of cellulosic fibers via the LbL technique with different cationic polyelectrolytes.
Topochemical analyses of furfuryl alcohol-modified radiata pine (Pinus radiata) by UMSP, light microscopy and SEM
Authors: Ehmcke Gabriele , Pilgård Annica , Koch Gerald , Richter Klaus 
Published: July 2017

Abstract
Furfurylation is one of the wood modification techniques via catalytic polymerization of the monomeric furfuryl alcohol (FA) in the impregnated cell wall. Little is known about the topochemistry of this process. Brown rot degradation begins with lignin modification and therefore, the reactions between FA and lignin was one focus of this research. Furfurylated radiata pine (Pinus radiata) with three different weight percent gains (WPGs of 57%, 60% and 70%) after FA uptake was observed by cellular ultraviolet microspectrophotometry (UMSP) to analyze chemical alterations of the individual cell wall layers. Moreover, light microscopy (LM) and scanning electron microscopy (SEM) analyses were performed. The ultraviolet (UV) absorbance of the modified samples increased significantly compared to the untreated controls, indicating a strong polymerization of the aromatic compounds. Highest UV absorbances were found in areas with the highest lignin concentration. The UMSP images of individual cell wall layers support the hypothesis concerning condensation reactions between lignin and FA.
Effect of tool wear on quality in drilling of titanium alloy Ti6Al4V, Part I: Cutting Forces, Burr Formation, Surface Quality and Defects
Authors: Eynian Mahdi , Das Kallol , Wretland Anders 
Published: July 2017

AbstractTitanium’s Ti6Al4V, alloy is an important material with a wide range of applications in the aerospace industry. Due to its high strength, machining this material for desired quality at high material removal rate is challenging and may lead to high tool wear rate. As a result, this material may be machined with worn tools and the effects of tool wear on machining quality need to be investigated. In this experimental paper, it is shown how drills of various wear levels affect the cutting forces, surface quality and burr formation. Furthermore, it is shown that high cutting forces and high plastic deformation, along with high temperatures that arise in cutting with worn tools may lead to initiation of microscopic cracks in the workpiece material in proximity of the drilling zone.
Effect of tool wear on quality in drilling of titanium alloy Ti6Al4V, Part II: Microstructure and Microhardness
Authors: Das Kallol , Eynian Mahdi , Wretland Anders 
Published: July 2017

AbstractDrilling of Ti6Al4V with worn tools can introduce superficial and easily measured features such as increase of cutting forces, entry and exit burrs and surface quality issues and defects. Such issues were presented in the part I of this paper. In part II, subsurface quality alterations, such as changes of the microstructure and microhardness variation is considered by preparing metallographic sections and measurement, mapping of the depth of grain deformation, and microhardness in these sections. Drastic changes in the microstructure and microhardness were found in sections drilled with drills with large wear lands, particularly in the dry cutting tests. These measurements emphasize the importance of detection of tool wear and ensuring coolant flow in drilling of holes in titanium components.
Preparation and Oxidation Behavior of Metallic Nickel Containing MgAlON Composite
Authors: Jinlin Yang , Hanxin Xiao 
Published: July 2017

AbstractTo survey the probability of the re-utilization of nickel containing slag corroded magnesia and alumina-graphite refractories, different amounts of nickel oxide (NiO) were used as one of raw materials to synthesize nickel containing magnesium aluminum oxynitride (MgAlON) composites, and the sintering and oxidation behavior have been explored in this work. The results reveal that with the increasing NiO additive, submicron metallic Ni grains are segregated from the (Ni,Mg)AlON spinel, and these grains are beneficial to improve thermal shock resistance of MgAlON. Though the oxidation reaction of (Ni,Mg)AlON starts at lower temperature than MgAlON, the metallic Ni grains in the plate can improve the oxidation resistance. Hence, the metallic nickel containing (Ni,Mg)AlON composite has not only superior thermal shock resistance but also excellent oxidation resistance, and it is of great potential to utilize in plant. So, the fabrication of metallic nickel containing (Ni,Mg)AlON composite should be a feasible way to reuse the nickel slag corroded magnesia and alumina graphite refractories.

Using Local ICT Services to Support Lower Secondary and Primary School Teaching
Authors: Šimandl Václav , Novotný Jakub 
Published: July 2017

Abstract
The article looks at the ways lower secondary and primary school pupils and teachers make use of ICT services (particularly user accounts and network drives). The description of implemented approaches is complemented by a discussion of the factors that influence schools in their choice of a particular solution. Attention has been devoted to both the various benefits that a chosen solution has brought to teaching and the complications that have been encountered during lessons. Our research has covered a wide range of schools that use services provided by servers to a varying extent as well as schools that are not in possession of servers. In-depth, semi-structured interviews have been carried out with school network managers. Our investigation has been supported by triangulation, consisting of interviews with teachers selected from the given schools. Data gained from the interviews has been processed using open coding. The results show that despite user accounts being found to be beneficial to teaching and lesson management, not all schools have access to such a solution. As well as being able to use personal and shared network drives, this solution can make it easier for schools to monitor their pupils′ Internet activity. Schools have their own specific procedures to deal with pupils that forget their login details, which could lead to lessons being disrupted. Schools that do not make use of user accounts have developed methods to overcome such a problem. It does not seem to be a lack of suitable solutions that prevents the more effective use of ICT in teaching. The problem is more likely to lie in the fact that many teachers lack knowledge of the various possibilities offered by available solutions and are often unwilling to make use of such solutions.
Relationship between age and outcome in thyroid surgery: a prospective observational study
Authors: Tabriz Navid , Uslar Verena Nicole , Tabriz Inga , Weyhe Dirk 
Published: July 2017

AbstractBackground:The occurrence of thyroid nodules and goiter increases with age. In general, surgery age is a predictor of perioperative morbidity. In thyroid surgery, there are different data on the role of age on morbidity. We investigated the influence of age on the outcome in thyroid surgery in a prospective single cohort study with a follow-up after 1 year.Methods:Total thyroidectomy or hemithyroidectomy was performed in euthyroid benign thyroid goiters (n=152). The primary endpoint was surgery duration. The secondary endpoints were weight of resected tissue, body mass index (BMI), amount and type of perioperative and long-term complications, and quality of life (QoL) preoperatively and 1 year postoperatively.Results:A significant three-way interactive relationship between age, surgery duration, and amount of resected tissue was found. An increase in any of these variables results in an increase in both other variables. The amount of perioperative complications was associated with resected tissue size. The QoL increases significantly after surgery by up to 10% and decreases significantly with age (mean QoL after surgery=84.9 of 100 for the youngest group and 75.7 of 100 for the oldest group). No long-term complications were recorded.Conclusion:The number of thyroid operations, especially of benign thyroid goiters, decreases annually in Germany. This can be explained by the fact that, on the one hand, the surgical indications are made more restrictive as conspicuous nodes are better clarified by improved technical aids. On the other hand, conservative measures (i.e. L-thyroxine and iodide administration) are used to achieve a size regimen of the goiter. Our results show that perioperative complications increase with patients’ age and surgery duration. However, the more restrictive surgical decision also entails the risk that patients will have to be operated at an older age and possibly with a bigger goiter, which is associated with higher operative morbidity. Therefore, in addition to the possibility of conservative therapy of the symptomatic goiter, the affected patients should also be thoroughly informed about the option to perform elective early thyroid surgery with regard to improved postoperative QoL and to keep the overall stress at a minimum for elderly patients.

Abstract
The European honey bee (Apis mellifera L.) is known to be affected by such stress factors as pathogen load, poor nutrition and depressed immunity. Nosema ceranae is one of the main parasites that affect colony populations. The relationship between the stress factors and honey bee-bacteria symbiosis appears as an alternative to enhance bee health. The aim of this study was to evaluate the effect of the oral administration of bacterial metabolites produced by Lactobacillus johnsonii AJ5 on nutritional parameters, the N. ceranae development and the performance of A. mellifera colonies. Laboratory assays were performed and demonstrated that the bacterial metabolites did not have a toxic effect on bees. Field trial showed an increase of colonies population over time. Also, a decreasing trend of fat bodies per bee was detected in all colonies but there were no evident changes on abdomen protein content at the end of the assay. Lastly, N. ceranae prevalence showed a tendency to reduce with the organic acids. Future studies should be performed to increase our knowledge of the physiological effects of bacterial metabolites on the health of bee colonies.
Effect of Artificial Prolonged Wintering on Emergence and Survival of Osmia Rufa Adults
Authors: Giejdasz Karol , Wasielewski Oskar 
Published: July 2017

AbstractThis study discusses the longevity and emergence rate of O. rufa males and females after an extended wintering period in artificial conditions. Experimental activation of the wintering bees was carried out every fifteen days, starting at the end of March and finishing at the beginning of June (25 March, 9 April, 24 April, 9 May, 24 May, 8 June). In our study, the shortest emergence time (5 days) was observed in females that overwintered for at least 220 days and were activated at the beginning of May or later. Their mean emergence time in the last three terms was similar and ranged from 4.6 to 5.1 days. Prolonged wintering increased female emergence dynamics in May and June. Half of the emerged males in our study lived up to 28 days when activated during the first term, and up to 15 days when activated during the last one. In females, half of the bees lived up to 64 and 20 days, respectively.
Return to work program efficacy with Self-Regulation Therapy (SRT®): Case study with complex trauma and concurrent disorders
Authors: Miller Tara 
Published: July 2017

Abstract

Background
This study shows the efficacy of treating complex cases neurobiologically using Self-Regulation Therapy (SRT®) within the context of return to work goals.

Case presentation
This is a single case study of a 32-year-old white female. This case study follows a client with concurrent diagnoses of post-traumatic stress disorder (PTSD), bipolar disorder I and substance abuse over the course of 2 years of treatment with SRT®. Using SRT® as primary modality and Likert Scale self-report on the Zettl Scale of Dysregulation, psychiatric medication monitoring and pharmaceutical tracking, this study shows session summaries and progress.

Results
After six sessions the client was cleared by her psychiatrist for return to work. Her medications were reduced and her post-traumatic symptoms abated. She no longer met diagnostic criteria for PTSD or substance abuse after nine sessions. She returned to work successfully and maintained sobriety and continued symptom reduction. Follow up over a 2-year time period showed consistency and continued improvements in both her professional and her personal life.

Conclusions
Clients with complex traumatic history with concurrent diagnosis are typically difficult to treat in traditional psychotherapy with limited long-term success. This creates challenges in therapy because the traumas occur during key developmental periods of life. This study shows the efficacy of treating complex cases neurobiologically using SRT®. Using SRT®, clinicians are able to address both developmental and complex trauma to reduce sympathetic arousal in the nervous system providing symptom reduction and even resolution of previous clinical diagnoses.
Differential Evolution Dynamics Modeled by Longitudinal Social Network
Authors: Skanderova Lenka , Fabian Tomas , Zelinka Ivan 
Published: July 2017

AbstractDifferential evolution (DE) is a population-based algorithm using Darwinian and Mendel principles to find out an optimal solution to difficult problems. In this work, the dynamics of the DE algorithm are modeled by using a longitudinal social network. Because a population of the DE algorithm is improved in generations, each generation of DE algorithm is represented by one short-interval network. Each short-interval network is created by individuals contributing to population improvement. On the basis of this model, a new parent selection in the mutation operation is presented and a well-known benchmark set CEC 2013 Special Session on Real-Parameter Optimization (including 28 functions) is used to evaluate the performance of the proposed algorithm.

Published: July 2017

Abstract
Musical pitch estimation is used to recognize the musical note pitch or the fundamental frequency (F
0) of an audio signal, which can be applied to a preprocessing part of many applications, such as sound separation and musical note transcription. In this work, a method for musical note recognition based on the classification framework has been designed using an optimization-based neural network (OBNN). A broad range of survey and research was reviewed, and all revealed the methods to recognize the musical notes. An OBNN is used here in recognizing musical notes. Similarly, we can progress the effectiveness of musical note recognition using different methodologies. In this document, the most modern investigations related to musical note recognition are effectively analyzed and put in a nutshell to effectively furnish the traits and classifications.

Published: July 2017

Abstract
This paper presents an elite opposition-based cognitive behavior optimization algorithm (ECOA). The traditional COA is divided into three stages: rough search, information exchange and share, and intelligent adjustment process. In this paper, we introduce the elite opposition-based learning in the third stage of COA, with a view to avoid the latter congestion as well as to enhance the convergence speed. ECOA is validated by 23 benchmark functions and three engineering design problems, and the experimental results have proven the superior performance of ECOA compared to other algorithms in the literature.
