Development of protection mechanisms against DRDoS-attacks and combined DRDoS-attacks
Authors: Bekeneva Yana , Shorov Andrey 
Published: June 2017

Distributed “denial of service” attacks based on the traffic reflection and amplification (DRDoS attacks) still are a powerful threat for computer networks. More than half of all attacks were executed by using multiple types of attacks. Development of new protection mechanisms against such attacks is one of the most important tasks in the field of computer security. In this paper, we present experiments on DNS attack, NTP attacks and combined DRDoS-attack simulation. We simulated several protection mechanisms as well as a mechanism developed by us. We compared these protection mechanisms for different kinds of attacks.

Abstract
Carbon-coated Fe3O4 porous particles were synthesized with phenolic resin as a carbon source using impregnating pyrolysis. The magnetic property, phase structure, pore structure, and surface morphology of the pyrolysis products were characterized by vibrating specimen magnetometer, X-ray diffraction, Brunauer–Emmett–Teller (BET), and scanning electron microscopy, respectively. Also, the adsorption properties of iron (III) ions on Fe3O4@C as well as pure carbon, including adsorption isothermal, kinetics, and pH effect, were investigated. The results showed that the size of synthesized Fe3O4@C particles ranged from 10 to 50 μm with micro-meso pores sized below 5 nm. The main phases of Fe3O4@C were magnetite, graphite and amorphous carbon. The adsorption kinetics of iron (III) ions on Fe3O4@C could be expressed by the pseudo-second-order kinetic model and the adsorption isotherm was fitted by a Freundlich model. Nano-Fe3O4 had synergism to porous carbon on the absorption of iron (III) ions.
Flood disaster level evaluation using a particle swarm optimization algorithm considering decision maker's preference

Published: June 2017

Abstract
There has been an increasing demand for accurately evaluating flood disaster levels in order to improve public safety and management of water resources. This article reviews the characteristics of the existing subjective and objective assessment methods, and introduces decision maker's preferences in the particle swarm optimization (PSO) algorithm for a better assessment of flood disaster level. The indicator weight vector of the fuzzy clustering iterative (FCI) model is used as the position vector of a particle in the approach herein proposed. The individuals that do not satisfy the preferences are screened out during the evolution process, in order to obtain more reasonable assessment results according to the preferences for the given scenario. The optimal weight vector of flood disaster samples is then obtained using FCI model combined with the proposed PSO with decision maker's preferences, referred to as PSODP algorithm. A case study of Xinjiang autonomous region of China demonstrates the results of flood rating using different decision maker's preferences, and provides several suggestions on preference type choice. This type of analysis could be used by the water conservation department to better classify the level of a disaster and channel resources accordingly, in the best way possible to manage the situation.

Радіочастотна нейроабляція крижово-клубового суглоба як метод лікування больового синдрому
Authors: Roy I.V. , Fishchenko I.V. , Kudrin A.P. 
Published: June 2017

Актуальність. Синдром (дисфункція) крижово-клубового суглоба (КПС) є основним джерелом болю попереково-крижового відділу хребта у 10–25 % пацієнтів. Радіочастотна нейроабляція КПС була запропонована як тривалий за ефективністю варіант лікування больового синдрому при нетривалому полегшенні симптомів після застосування внутрішньосуглобових ін’єкцій гормональних препаратів. Мета дослідження: аналіз ефективності застосування радіочастотної нейроабляції крижово-клубових суглобів. Матеріали та методи. Проаналізовано дані 15 пацієнтів (3 чоловіки та 12 жінок) віком від 14 до 91 року, які пройшли амбулаторне лікування у відділенні реабілітації ДУ «Інститут травматології та ортопедії НАМН України». Результати. Було встановлено зниження больового синдрому за візуально-аналоговою шкалою (ВАШ) з 6,95 ± 0,25 на момент звернення до 3,90 ± 0,35, 3,10 ± 0,28 и 2,80 ± 0,36 після процедури, через 6 і 12 міс. відповідно. Дані оцінки якості життя за опитувальниками Оswestry Disability Index і Роланда — Морріса на всіх етапах спостереження корелюють з даними больового синдрому за ВАШ (при початковому обстеженні rcan = 0,77, на момент остаточного спостереження rcan = 0,97). Висновки. Радіочастотна нейроабляція — ефективний метод лікування больового синдрому крижово-клубового суглоба.
Постпрандіальний гіпоглікемічний синдром
Authors: Chaychenko Т.V. 
Published: June 2017

Постпрандіальний гіпоглікемічний синдром, або реактивна гіпоглікемія, — вегетативні симптоми, такі як слабкість, втома, голод, нудота, серцебиття, занепокоєння, тремор, пітливість, що виникають через одну-дві години після прийому їжі. Синдром досить слабо висвітлений у літературі, більшість відомостей є розрізненими. Лабораторні критерії діагностики постпрандіальної реактивної гіпоглікемії досить контроверсивні, але більшість авторів схиляються до того, що це рівень глюкози крові нижче тощакової або ≤ 3,9 ммоль/л протягом двох годин після прийому їжі. Гіпоглікемія є результатом дисбалансу між надходженням глюкози в кров (від ендогенної продукції глюкози або екзогенної доставки) і використанням глюкози тканинами. Баланс між надходженням і витрачанням глюкози контролюється складною рівновагою глікорегулюючих гормонів. Інсулін, глюкагон і адреналін діють протягом кількох хвилин, а кортизол і гормон зросту — кілька годин. Це пояснює наявність негайних і відстрочених різноманітних ефектів: адренергічного, нейроглікопенічного, гастроінтестинального дискомфорту. Відомо, що в генезі постпрандіального синдрому лежать механізми, подібні до постгастректомічних у пацієнтів, оперованих з приводу морбідного ожиріння. Найбільш імовірним чинником формування реактивної гіпоглікемії є постпрандіальна гіперсекреція інсуліну під впливом глюкози і глюкагоноподібного пептиду (GLP-1), що є компонентом ентероендокринної системи, основна дія якого спрямована на цефалічну фазу формування насичення. Як у оперованих пацієнтів, так і у відносно здорових осіб симптоми виникають після прийому їжі, багатої простими вуглеводами. Симптоми досить ефективно лікуються прийомом їжі з вживанням вуглеводів із низьким глікемічним індексом і харчовими волокнами. При недостатності ефекту використовують препарати акарбози, інгібуючої α-глюкозидази тонкого кишечника, що є основним стимулом для секреції GLP-1. Таким чином, при епідемічній швидкості поширення ожиріння в умовах неадекватних харчових пріоритетів у дитячій популяції ймовірність значної поширеності постпрандіального синдрому досить вірогідна, що вимагає додаткового дослідження. При цьому зниження в раціоні простих вуглеводів може істотно поліпшити якість життя дітей із постпрандіальним дискомфортом.

Published: June 2017

Fringelip mullet (Crenimugil crenilabis) caught at Al Duqum and Salalah in the Arabian Sea region of Omanwere sampled monthly between January 2001 and December 2002. The total length (TL) of mullet caught with gill- and seine nets ranged from 12 to 54.5 cm (32.4 cm mean ± SD; n = 2445) but <2% of specimens had a TL<24 cm, suggesting gear selectivity. Females dominated samples (1 : 0.36) and reached L at 32.8 cm TL (32.2 cm in males). Length weight relationships were non-linear and conversion factors between TL, fork length (FL) and standard length (SL) were calculated. Proportionately, most females had ripe gonads in September and October, and males in September to November. Both female and male gonadosomatic indices (GSI) peaked in September and October and were lowest between May and August. The peak in reproductive activity coincides with the fall intermonsoon, when the Arabian Sea upwellings caused by the onshore winds of the SW monsoon season (June to August/September) retreat. During this intermonsoon period the inshore water temperatures begin to rise after reaching a minimum in August/September. Some reproductive activity also occurs in other months, particularly February, when water temperatures are seasonally lower.
Yield-per-Recruit and Relative Mean Biomass Estimates, and their Management Consequences, to the Penaeus Indicus Fishery in the Gulf of Masirah
Authors: Siddeek M. S. M. , Mohan R. , Johnson D. W. 
Published: June 2017

The von Bertalanffy growth parameters estimated based on the 1990/91 carapace length data of Penaeus indicus from the Gulf of Masirah, Oman were used to calculate total mortality, yield-per-recruit ( i.e. average weight of a shrimp from a cohort under a given fishing pattern) , and relative mean biomass ( i.e. exploited cohort biomass over un-exploited cohort biomass) for the population sampled. The instantaneous total mortality coefficient value indicated under exploitation in 1990/91. When different fishing seasons scenarios were considered with the current total mortality level but with a range of natural mortality values, high yield, per recruit and relative mean biomass values were shown for October-April and November-April fishing seasons. The fishing season is currently late August to end of April. Thus, a one to two-month delay in the fishing season appears to be beneficial to this fishery.

Background: Over the last three decades the annual number of deaths among children less than 5 years of age has decreased by almost one third. However, this reduction has not been evenly distributed throughout the worldObjective: The aim of the present study was to identify the role perception of mothers and nurses in the care of hospitalized children.Method: Comparative survey design was adopted for the study. A simple random sampling technique for mothers and purposive sampling for the nurses were used in selecting the subjects. The sample comprised of 50 mothers and 50 nurses. The data was collected by using interview schedule for mothers and semi-structured questionnaire for the nurses. The data obtained was analyzed using the descriptive and inferential statistics.Result: The study results showed that, 84% of mothers strongly agreed and 56% of nurses strongly agreed, with the role of mothers in the care of hospitalized children. Regarding comparison of the role of mothers as perceived by mothers and nurses, were found positively significant. As regards to relationship between the perceptions of mothers on her role with the selected background factors, revealed that there was no significant relationship.Conclusion: Mother’s role in the care of hospitalized children is vital, as all expectations of satisfaction, trust and security of the child are vested in her. Mothers being a primary care provider of child has limited role in hospital but still can contribute in recovery of children.Health Renaissance 2015;13(2): 14-21
Improving the productivity and purity of vaterite produced via a refined bubbling method
Authors: Chen Peiyuan , Ma Honghao , Xu Ying , Shen Zhaowu 
Published: June 2017

Abstract
The bubbling method has been refined to produce vaterite with both high productivity and purity for its promising applications. This involves: a) adding an adequate amount of ammonia water to achieve maximum precipitation of Ca2+, b) refining CO2 bubble sizes into microns by a designed gas disperser, and c) using optimal final pH condition and CO2 flow rate to obtain vaterite with both high productivity and purity. In addition, the conservation of vaterite was also investigated by exposing vaterite to two moist environments. The results show that 95.1 % pure vaterite can be produced with 88.8 % yield at a final pH value of 8.6 and CO2 flow rate of 11 l min−1. The corresponding vaterite particles mostly have a hollow structure. The conservation of vaterite is very sensitive to moisture, and it transforms into calcite gradually depending on the moisture content.

Published: June 2017

In the present study, aerial parts of Nepeta cilicica were hydro-distilled for the essential oil. Furthermore, air-dried plant materials were extracted with methanol. According to GC-MS results, 35 compounds were characterized in the oil (totally 92%). Caryophyllene oxide, ?-caryophyllene and spathulenol (28.2, 8.9 and 4.2%) were found as main components of the oil. Sixteen compounds were detected by LC/MS, most of which were caffeoylquinic acid, luteolin and apigenin derivatives, in methanolic extract of the N. cilicica. Apart from DPPH radical scavenging activity, inhibitory effects on bacterial and yeast growth of essential oil and the methanolic extract were evaluated. Twenty-four different pathogenic bacterial and Candida strains were tested by M7-A7 and CLSI M27-A2 protocols respectively. The crude extract showed better inhibitory effects against bacteria strains than the essential oil. Both oil and the extract demonstrated strong inhibition on C. tropicalis at a concentration of 47.0 µg/mL (MIC).

Published: June 2017

BackgroundChildren who do not attend (DNA) their hospital outpatient appointments are a concern because this potentially compromises the child’s health and incurs financial cost. Little is known about children who DNA or the views of GPs to non-attendance.AimTo describe the characteristics of children who DNA hospital paediatric outpatient appointments, and explore how GPs view and respond to DNAs.Design and settingA mixed methods study of data from all new referrals to a children’s hospital in the South West of England between 1 September and 31 October 2012.MethodData were extracted from patients’ hospital and GP records, and Stata was used to analyse the data quantitatively. Analysis focused on describing the characteristics of children who DNA, and the process of care that followed. Practices that had either the highest or lowest number of DNAs were purposefully sampled for GPs who had referred children to secondary care at the study hospital within the previous year. Interviews were held between May 2014 and July 2015, and were analysed thematically.ResultsChildren who DNA are more likely to be from an area of greater deprivation (adjusted odds ratio [AOR] 1.02, 95% confidence interval [CI] = 1.00 to 1.02, P = 0.04), and with a child protection alert in their hospital notes (AOR 2.72, 95% CI = 1.26 to 5.88, P = 0.01). Non-attendance is communicated poorly to GPs, rarely coded in patients’ GP records, and few GP practices have a formal policy regarding paediatric DNAs.ConclusionNon-attendance at hospital outpatient appointments may indicate a child’s welfare is at risk. Communication between primary and secondary care needs to be improved, and guidelines developed to encourage GPs to monitor children who DNA.
Spectral Method Approximation of Flow Optimal Control Problems withH1-Norm State Constraint
Authors: Chen Yanping , Huang Fenglin 
Published: June 2017

AbstractIn this paper, we consider an optimal control problem governed by Stokes equations withH1-norm state constraint. The control problem is approximated by spectral method, which provides very accurate approximation with a relatively small number of unknowns. Choosing appropriate basis functions leads to discrete system with sparse matrices. We first present the optimality conditions of the exact and the discrete optimal control systems, then derive both a priori and a posteriori error estimates. Finally, an illustrative numerical experiment indicates that the proposed method is competitive, and the estimator can indicate the errors very well.
