Quasi-Euclidean duo rings with elementary reduction of matrices

We establish necessary and sufficient conditions under which a class of quasi-Euclidean duo rings coincides with a class of rings with elementary reduction of matrices. We prove that a Bezout duo ring with stable range 1 is a ring with elementary reduction of matrices. It is proved that a semiexchange quasi-duo Bezout ring is a ring with elementary reduction of matrices iff it is a duo ring

Іронія Оґдена Неша (Orgen Nash`s irony)

У цій роботі ми розглядаємо іронію у когнітивно-комунікативному аспекті, спираючись на теорію інференційної моделі комунікації Д. Спербера і Д. Уілсон. Особливостями іронії Оґдена Неша ми вважаємо таке: (а) позитивне і прийнятне з точки зору суспільства представлено як неадекватне, а отже, сміховинне; (б) автор може насміхатися з головного персонажа/наратора, але гадана недолугість останнього спричинена невідповідністю суспільним нормам і поглядам; це створює ефект «непрямої», «переадресованої» іронії; (в) авторська іронія м’яка; у ряду форм комічного гумор – іронія – сарказм вона тяжіє радше до першої, ніж до останньої. (Ogden Nash’s irony is a very specific phenomenon. The number of poems whose irony can be traditionally regarded as critical attitude under the guise of praise is comparatively small. For the purpose of this article, irony is viewed from a cognitive/communicative perspective. Our research is based on the inferential model of communication put forward by Relevance Theory (D. Sperber and D. Wilson). Researching the nature of irony, Sperber and Wilson begin with the philosophical principle of use and mention. Use is a statement about reality. An ironic utterance does not make any statement, it makes mention of other people’s words or ideas, even of those ideas that have not been explicated, but, in the speaker’s opinion, may be entertained. Irony is regarded as echoic mention. A speaker dissociates themselves from the content of an utterance; their intention is to express critical attitude to what has been said or to conventionally or situationally ascribed opinions. The distinctive features of Ogden Nash’s irony are as follows: (a) things that are considered to be appropriate by society are presented as inappropriate, ridiculous; (b) by the look of it, the author mocks the main character/narrator; but the latter’s seeming lack of particular qualities results from disagreement with conventional views of their social environment; hence the effect of «indirect», redirected irony; (c) the author’s irony is gentle; in the line humour – irony – sarcasm, this form of creating comic effect tends to the former rather than the latter.

ОСОБЕННОСТИ РАСПРОСТРАНЕНИЯ И ПРИЧИНЫ РИСК-ОРИЕНТИРОВАНОГО ПОВЕДЕНИЯ В МОЛОДЕЖНОЙ СРЕДЕ (НА ПРИМЕРЕ УПОТРЕБЛЕНИЯ ПСИХОАКТИВНЫХ ВЕЩЕСТВ) Куковская И.Л., Иванушко Я.Г., Романив Л.В., Пылып Г.Н., Пишак О.В., Логуш Л.Г. Черновицкий национальный университет имени Ю.Федьковича, ул. Коцюбинського 2, г. Черновцы , 58012, Украина Целью представленного исследования было изучение мнения студентов высшего учебного заведения о возможных ситуациях и причинах употребления их сверстниками веществ, которые могут вызывать зависимость, так называемых психоактивных веществ (табакокурение, употребление алкоголя, наркотических средств, энергетических напитков), являются факторами риска и способствуют развитию ряда социально-значимых заболеваний. Исследование не предусматривало изучение распространения вредных привычек среди молодежи, а только анализ их ответов относительно ситуаций и причин указанных явлений. В исследовании приняли участие 137 студентов возрастом от 17 до 21 года. Установлено, что большинство опрошенных не могут определить одну наиболее весомую причину, но указывали несколько таких причин и ситуаций. Показано, что по мнению молодых людей, более свободному употреблению психоактивных веществ в молодежной среде способствует, прежде всего, посещение дискотек, встречи с товарищами, которые проходят на фоне отсутствия интересных занятий и увлечений, а также ситуации, сопровождающиеся недостаточным уровнем контроля со стороны взрослых, в том числе во время каникул. Анализ результатов исследования дает основание сделать предположение о недостаточном уровне навыков выхода из «некомфортных» психологических ситуаций среди молодежи. Результаты опроса показывают ключевое влияние семьи и социального окружения на степень проявления риск-ориентированного поведения молодежи. Принимая во внимание существенный вклад факторов риска в показатели состояние общественного здоровья, анализ процессов формирования и восприятия рисков для здоровья в молодежной среде требует особого внимания. Проведение дальнейших систематических социологических исследований, которые будут обуславливать направление и влиять на качество программ здоровьесбережения представляется актуальным и целесообразным.

Yuriy Fedkovych Chernivtsi National University,2 Kotsjubynskyi Str., Chernivtsi 58012, Ukraine Summary: The aim of the present study was to investigate the university students’ views of possible situations and the reasons for the use of substances that can be addictive by their peers. So-called psychoactive substances (tobacco, alcohol, drugs, energy drinks) can act as risk factors and contribute to the development of a number of socially significant diseases. The study did not provide for the study of the spread of harmful habits among young people, but only an analysis of the responses concerning the situation and the reasons for these phenomena. The study involved 137 students aged 17 to 21 years. It was found that the majority of respondents can not identify a single best reason, but pointed out a few of these reasons and situations. It is shown that in the opinion of young people, the freer use of psychoactive substances among young people is primarily promoted by visits to discos, meeting with friends who are on the background of the lack of interesting activities and hobbies, as well as the situation, accompanied by an insufficient level of adult supervision, including the holidays period. Analysis of the study results suggests a lack of skill level output from "uncomfortable" psychological situations among young people. The survey results indicate key influence of family and social environment on the degree of the risk-oriented behavior manifestation of young people. Taking into account the significant contribution of risk factors in the state of public health indicators, analysis of the processes of formation and perception of health risks among young people requires special attention. Conducting further systematic sociological studies, which will condition the direction and influence the quality of health preservation programs seems relevant and appropriate. Keywords: students, the reasons, the situation, the risk-oriented habit

Dynamical lymphadenectomy as a component of multidisciplinary approach while doing operative interventions for pancreatic cancer

Objective. To improve the results of treatment of pancreatic cancer, using modification of volumes of lymphadenectomy and application of multidisciplinary approach. Materials and methods. Into the investigation 16 patients, suffering a moderately differentiated (G2) adenocarcinoma of the pancreatic gland head (II stage of the disease) were included. There were 10 men and 6 women. The average age of the patients have constituted 62.4 yrs old. The patients were divided into two groups – the main and the comparative one, equally - by 8 of every group. In all the patients pancreaticoduodenal resection was done. All the patients in postoperative period have obtained gemcitabine in combination with 5-fluorouracyl. In patients of the main group a dynamical personalized intraoperative lymphadenectomy in accordance to our elaborated scheme, was performed. In patients of the comparison group lymphadenectomy was performed in accordance to the volumes adjusted, and it is called a standard one. Results. Average duration of the operation have constituted (347 ± 48) min, lymphadenectomy – (42 ± 12) min in the main group, and (31 ± 9) in the comparison group. Average volume of the blood loss have constituted (342 ± 272) ml. Average duration of hospitalization have constituted (8.2 ± 4.3) days, general rate of postoperative complications – 24.3% in both groups. After the operation the mortality was absent. Clinically significant lymphorrhea was observed in 3 patients in the main group, and in 5 – from the comparison group. In patients of the main group 9 ± 2 lymph nodes were excised, and in a comparative one – 13 ± 2, there were revealed 7 ± 1 (77.7%) and 9 ± 2 (60%) lymph nodes affected, accordingly. Postoperative diarrhea have occurred in 4 patients: in 3 – from comparative group, and in 1 – from the main group. Duration of the recurrence-free period in the main group have constituted (18 ± 2.3) mo, and in a comparative one – (13 ± 1.5) mo. Two years have survived 12/16 (75%) patients. In the main group one patient died, and in a comparative one - 3. The two-year survival in the main group have constituted 87.5%, and in a comparative one – 62.5%. Conclusion. Dynamical lymphadenectomy as a component of multidisciplinary approach gives possibility to reduce the quantity of the lymph nodes excised, unaffected by the tumor, to enhance the quantity of the excised lymph nodes trustworthily affected by the tumor, to lower the morbidity rate and to prolong the duration of the recurrence free period
