Реферат: The article presents the author\'s concept of the Kazakh ethno-pedagogy, developed on the basis of many years research. Devoted to disclosing theoretical and methodological foundations of ethno-pedagogy and Kazakh ethno-pedagogy, substantiation of its scientific status and place in the system of the human sciences. In the article, ethno-pedagogy is seen as an integrative branch of pedagogy, which was formed in the womb of pedagogy, at the junction of ethnic psychology, ethnophilosophy, ethnology, and ethnoculturology, which has its object and subject of research and conceptual and terminological apparatus. The introductory part of the article provides a brief analysis of the historical-pedagogical and scientific-theoretical assumptions of ethno-pedagogical ideas in Kazakhstan. The final part of the article presents ethno-pedagogical development tendencies, prospects of research, and ethno-pedagogy as a science and academic discipline.

Ключевые слова: полиамидбензимидозол*диметилацетамид*вязкость раствора*фазовое расслоение, критическая температура распада*концентрация полимера*
Реферат: Исследована вязкость и фазовая устойчивость растворов жесткоцепного полиамидбензимидазола и его сополимера с поли-n-фенилентерефталамидом в диметилацетамиде при течении в широком диапазоне температур и скоростей сдвига. Эти системы характеризуются аморфным расслоением с нижней критической температурой смешения. В области температуры фазового разделения вязкость проходит через минимум вследствие формирования микроэмульсии с последующим обратимым застудневанием системы в результате незавершенного распада на фазы, сопровождаемого ее помутнением. Температура фазового распада и достижения минимума вязкости исследованных растворов снижается с повышением концентрации полимера и возрастает с увеличением скорости сдвига.
Modification of Titanium Oxide Films by Ferric Ions in Hydrothermal Conditions and their Photo-Electrochemical Properties
Реферат: Anodic titanium oxide films were doped using ferrum ions in hydrothermal conditions. Doping is accompanied by a full change in the structure and morphology of the surface of titanium oxide while anatase is established radiographically. Deep redshift in optical spectrum of titanium oxide takes place. This is accompanied by anodic photo-current sharply increasing 2.5 times under visible lighting with simultaneous decrease of current characteristics under ultraviolet lighting. This is explained by the synergistic effect of Fe-Ti compound formed on the surface of the anodic oxide. Firstly, deep acceptor levels of ferrum in titanium oxide energy band gap are created while dopant conductivity becomes prevalent and titanium oxide\'s own conductivity partially leveled. Secondly, its proper layer of ferrum oxide is formed.

Автор(ы): Turtabaev S. K.*Kedelbaev B. Sh.*Shalabaeva G. S.*Sarbaeva K. T.*
Реферат: This work develops the technique and technology of modification by ferroalloys of floatable nickel catalysts of hydrogenation of benzene. It in detail studies the influence of the nature of metal of the catalyst, the modifying additives, the size of particles, technological parameters. They worked up reliable data on phase, granulometric and chemical structures, porous structure explaining activity, selectivity and stability of catalysts. The synthesized nickel catalysts are tested in the course of hydrogenation of benzene to cyclohexane in the liquid phase.

Реферат: A new recycling technology has been studied in this work to produce magnesium chloride from wastes generated in chrysotile asbestos production. The steps include enrichment of raw material by sizing, leaching of magnesium with hydrochloric acid, purification of solution from impurities of iron and nonferrous metals, and the production of magnesium chloride solutions. Thermodynamic analysis shows the possibility of dissolution of magnesium compounds in the waste by hydrochloric acid. Magnesium chloride solution is subjected to hydrolytic purification from iron and nickel. Enrichment has been carried out with material particle size of 0.25 mm and liquid to solid ratio of 4:1 and leaching with 25% concentrated hydrochloric acid has been accomplished with a stoichiometric flow rate. Hydrolytic treatment was carried out at a pH 7.5-8.0. pH adjustment was carried out by magnesium oxide. Extraction of 92% of magnesium from serpentinite was achieved.

Реферат: Birth defects (BD) constitute an important public health issue as they are the main cause of infant death. Their prevalence in Europe for 2008-2012 was 25.6 per 1000 newborns. To date, there are no population-based studies for the Russian Federation. The aim of the present study is to estimate the prevalence of BD, its forms, and changes over time in the Russian Arctic city of Monchegorsk (Murmansk County) for the period 1973-2011. The observed perinatal prevalence of BD in Monchegorsk increased two-fold during the 38-year study period. Further investigations to identify the underlying bases for the observed progressive growth in BD are recommended.

Determination of Quality Requirements in Tourism Management and Finance Departments of Akhmet Yassawi University by Kano Model
Ключевые слова: туризм*управление туризмом*модель Кано*качество высшего образования*финансы*
Реферат: In this study the information was given regarding Kano\'s Model and a case study was conducted for university students. Kano\'s Model was applied for Akhmet Yassawi University students and it was questioned what they thought were important quality requirements in higher education, the degree of their importance and how they evaluated their own institutions with respect to the quality requirements. The purpose of this study is to determine the student requirements regarding the quality of the undergraduate programs of Tourism Management and Finance in Akhmet Yassawi University and to analyze the student satisfaction and dissatisfaction and their majority roles in determining and improving the quality of the programs. To achieve this object, firstly Kano\'s Survey was applied to 116 students and the student requirements relating to the education were uncovered by focusing on group work. Secondly, these requirements were classified by Kano Evaluation Table. Thus, the quality requirements divided into four categories: must-be, one-dimensional, attractive and indifferent. Finally, the values ofsatisfaction and dissatisfaction were calculated and the roles of these requirements in increasing and decreasing student satisfaction and dissatisfaction were identified clearly.

Автор(ы): Жунисова М. Б.*Шалхарова Ж. С.*Шалхарова Ж. Н.*Нускабаева Г. О.*Садыкова К. Ж.*Маденбай К. М.*Гржибовский А. М.*
Реферат: Оценивалась распространенность различных уровней стресса в г. Туркестан Южно-Казахстанской области Республики Казахстан, изучалась связь между уровнем стресса и типами пищевого поведения в казахстанской популяции. Туркестанский регион считается одной из неблагоприятных зон республики и находится в предкризисном экологическом состоянии. В поперечное исследование были включены 637 человек из прикрепленного контингента поликлиники Международного казахско-турецкого университета. Уровень стресса устанавливался с помощью международного валидированного вопросника восприятия стресса PSS-10 (Perceived Stress Scale-10). Пищевое поведение оценивалось по голландскому вопроснику пищевого поведения. Для определения связи между стрессом и пищевым поведением использовались мультиномиальные логистические и многомерные линейные регрессионные модели.

Реферат: Research concerning potential long-term consequences of the condition for the offspring, is limited, but lack of nutrition in-utero has been associated with chronic disease in adulthood, including some cancers. There is growing evidence that several forms of cancer may originate during fetal life. We conducted a large study linking the high-quality population-based medical birth- and cancer registries in Norway, Sweden and Denmark, to explore whether hyperemesis is associated with increased cancer risk in offspring. The main finding of this paper is that hyperemesis does not seem to increase cancer risk in offspring. The positive association to lymphoma may be by chance and needs confirmation.
