Bu
çalışmanın amacı, sağlık çalışanlarının örgütsel kronizm ve işgören
performansına ilişkin algılarını incelemek ve örgütsel kronizm algılarının
işgören performansı üzerindeki etkisini ortaya koymaktır. Çalışmada, Antalya
ilinde bir kamu hastanesinde çalışmaya katılmak isteyen tüm sağlık
çalışanlarına anket uygulanmış ve 316 kullanılabilir anket elde edilmiştir. Bu
çalışmada sağlık çalışanlarının örgütsel kronizm algılarının orta düzeyde ve
işgören performansı algılarının ise yüksek düzeyde olduğu belirlenmiştir. Örgütsel
kronizm boyutlarından işlem kronizminin mevcut hastanede çalışma süresi;
terfide kronizmin eğitim, hastanedeki görev ve mevcut hastanede çalışma süresi
ve işe alma sürecinde kronizmin ise cinsiyet ve mevcut hastanede çalışma
süresine göre istatistiksel olarak anlamlı bir farklılık gösterdiği
belirlenmiştir (p&lt;0,05). İşgören performansının ise yaş, eğitim düzeyi,
hastanedeki görev ve mevcut hastanede çalışma süresine göre istatistiksel
olarak anlamlı bir farklılık gösterdiği tespit edilmiştir (p&lt;0,05). Ayrıca katılımcıların örgütsel kronizm
algılarının (işlem kronizmi, terfide kronizm ve işe alma sürecinde kronizm)
yükselmesinin işgören performansı algılarını istatistiksel olarak azalttığı
saptanmıştır. Bu sebeple örgütsel kronizm algısının düşürülmesi hem sağlık
kurumları hem de sağlık çalışanları açısından fayda sağlayacaktır.

Published: December 2018

В настоящее время инновационные компании являются одним из ключевых драйверов мирового рынка слияний и поглощений, что обусловливает актуальность выявления их особенностей, а также исследования вопросов эффективности подобных сделок. Вместе с тем в современной академической литературе отсутствует однозначные ответы на вопросы о том, какую компанию можно считать инновационной, каким образом определить уровень ее инновационности, что такое инновационная сделка по слиянию и поглощению и какими особенностями она обладает. Крайне мало внимания уделяется международным инновационным сделкам по слияниям и поглощениям и определению их особенностей. В данной статье приводится краткий обзор имеющейся литературы на данную тему. Описываются способы определения инновационной компании и основные подходы для оценки эффективности инновационных сделок по слияниям и поглощениям. Рассматриваются также международные инновационные сделки по слияниям и поглощениям и их особенности. По результатам проведенного обзора был получен вывод о том, что в большинстве работ инновационность определяется через абсолютную величину различных показателей, список которых приводится в данной статье, или с помощью специальных опросников, которые направляются менеджменту компании. Инновационные компании также могут быть определены исходя из отраслей, в которых задействованы компании. Для определения эффективности инновационных сделок по слияниям и поглощениям, как правило, используются показатели, связанные с приростом или цитируемостью имеющихся патентов у компании. Однозначного ответа на вопрос о влиянии сделок по слияниям и поглощениям на инновационную активность компании дать не удалось, так как результаты исследований имеют противоречивый характер. Основным же мотивом международных инновационных сделок по слияниям и поглощениям является приобретение новых технологий для получения конкурентных преимуществ. Тем не менее полное представление об эффективности данного типа сделок отсутствует.

Uml based test cases generation for the centralised control system of high speed maglev
Authors: Zhang Lun , Zhao Wenwen , Zhang Xiyu 
Published: December 2018

Background: The high speed maglev centralized control subsystem (CCS), which realizes the display, automatic train operation (ATO) and diagnose. The CCS is an important security assurance for train operation. System testing (ST) can detect design defects early and performed effective repair to improve the efficiency of the system’ on-site coordinated operation. Therefore, the quality of test cases directly determines the achievements and efficiency of CCS, and it is necessary to be tested before put it into use.
Aim: The generation of test case of centralized control subsystem is proposed.
Methods: In order to meet the requirements of the system, the first step is operating the extraction of functional features. Then, the unified modeling language is using to develop the test model in this paper. Then the corresponding unified modeling language models, use case diagram, state diagram, activity diagram and sequence diagram, are developed. The state diagram of operation process is using to describe the state transition during the period from initial state of the OTS to the completion of the operation. The activity diagram of train operation process focuses on the control relationship during the period from one activity to another, which can describe the interaction exactly between OTS, DCS and VCS. The sequence diagram, behavior of use case, focuses on the sequence of information sent by objectives, in which a group of objectives and information transfer are presented. And according to these models, the test cases of the specified case are generated.
Results: The generated test cases are all executed in the developed lab-test system. The results show that the generated test cases can fully simulate the common situations of the operation scene, and effectively improve the test efficiency and test quality. We designed the experiments as followings: 85 test cases for terminal system design of operator, 68 test cases for train automatic operation design, 31 test cases for central diagnostic system design. All of the designed test cases are examined through the test platform, covering all main scenes in operation process. The errors or detects found in tests are solved by finding the reasons and modifying the code, etc. Finally, the pass rate of the method proposed in this paper is 100 %.
Conclusion: The UML based method of test case generation implements the generation process and achieves the test cases and verification for CCS. Through the test practice, test cases designed can fully simulate all kinds of common situations in the operation site. What’s more, the test cases also realize early detection of errors and defects in the system and repair them. It is useful to improve the efficiency on-site testing process, to reduce the cost of time and test quality. The method can provide theoretical basis and reference for further testing of high speed maglev CCS.

Être ou ne pas être post(-)coloniale : le cas de la littérature des intrangers
Authors: Marcu Ioana 
Published: December 2018

Résumé : Dans l’espace francophone, parler de « littératures postcoloniales » représente un véritable défi. D’une part, il s’agit d’un courant littéraire envisagé avec méfiance, voire même réticence et hostilité, malgré les écrivains et les philosophes français et francophones cités comme précurseurs. De l’autre part, les caractéristiques éclectiques du corpus postcolonial donnent lieu à un rassemblement sous un même label d’œuvres littéraires protéiformes (aussi bien sur le plan de l’espace et de l’époque d’émergence que sur le plan des problématiques traitées et de la langue d’écriture) ; parallèlement, elles entraînent une mise à l’écart d’un ensemble littéraire hybride (à cause de l’histoire personnelle des écrivains et de leur langue d’expression). Dans notre contribution, nous nous proposons de voir si la littérature des intrangers, produite par les descendants d’immigrés maghrébins ou de harkis, présente vraiment les caractéristiques du corpus post(-)colonial. Nous fonderons notre analyse sur deux romans de l’extrême contemporain appartenant à deux écrivaines ayant connu un destin complètement différent : Un homme, ça ne pleure pas (2014) de Faïza Guène, chouchou des médias, cadette d’une famille originaire d’Algérie, née à Bobigny et ayant grandi dans la cité des Courtillières à Pantin, et Mohand le harki (2003) de Hadjila Kemoum, elle-même fille de harki.Mots-clés : post(-)colonial, intrangers, hybride, harkis, immigration.Abstract : In the French-speaking space, talking about “postcoloniales literatures” represents a real challenge. It is about a literary movement envisaged suspiciously, even reluctant and hostile, despite the French and Francophone writers and philosophers cited as being the precursors. On the other hand, the eclectic peculiarities of the postcolonial corpus give rise, at the same time, to a gathering under the same label of protean literary works, from the point of view of the space and of the period of emergence as well as the point of view of the problems treated and of the language of writing. Meanwhile, it also considers the hybrid corpus because of the personal history of the writers and of their language of expression. In our contribution, we investigate whether the literature of intrangers, produced by the descendants of Maghrebi immigrants or harkis, really presents the characteristics of the post(-)colonial corpus. We base our analysis on two novels of two contemporary female writers who knew a completely different destiny: Un home, ça ne pleure pas (2014), of Faïza Guène, younger child of an Algerian family, born in Bobigny and raised in Courtillières, and Mohand le harki (2003), of Hadjila Kemoum, herself girl of harki.Keywords : post (-) colonial, intrangers, hybrid, harkis, immigration.

Authors: Ildarova R. A. , Shkolnikova M. A. , Termosesov S. A. 
Published: December 2018

Purpose: to assess specificities of course of the long­QT syndrome in children before and after implantation of cardioverter­defibrillator (ICD), and optimization of indications to ICD­therapy.Materials and methods. We included in this study 48 children with long­QT syndrome from 44 unrelated families (28 boys and 20 girls), who underwent ICD implantation at the mean age 11.8±3.8 years. Mean duration of follow­up after implantation was 5.2±2.8 years. Data from these children were compared with those from 59 children of comparable age and gender with long­QT syndrome from 46 unrelated families receiving antiarrhythmic therapy (β­adrenoblockers). We assessed clinical and electrocardiographic characteristics of the disease obtained at initial visit and their dynamics thereafter.Results. Children with long­QT syndrome and ICD were mainly probands with interval QT longer than 500 ms, recurrent syncope and often history of sudden cardiac arrest requiring high doses of β­adrenoblockers for control of ventricular tachyarrhythmias.Conclusion. ICD implantation is an effective and safe method both of primary and secondary prevention of sudden cardiac death in children with long­QT syndrome.

Acute myocardial infarction (MI), the most severe complication of coronary artery disease, develops in 2-4% of patients with various malignancies.Purpose: to explore the specific properties of ST-segment elevation myocardial infarction (STEMI) course in patients with cancer and its effect on short-term outcome.Materials and methods. We included in this study 45 patients with STEMI and history of cancer hospitalized in the period from 01.01.2015 to 01.01.2017 (group I; 58% men, mean age 69.07±11.60 years). In the comparison group (group II) we selected 90 age and gender matched persons (58% men, mean age 68.16±11.75 years) from patients with STEMI without oncological diseases.Results. There were no differences between groups in main risk factors of cardiovascular diseases, except greater proportion of patients with damage of peripheral arteries in group 1 (22.2% compared with 5.6% in group 2, p=0.025). There were also no differences between groups in clinical characteristics at admission. However values of the following parameters were significantly lower in group I: concentration of hemoglobin (115.56±23.07 vs. 133.70±16.45 g/l in group 2, р<0.001), red blood cell count (3.95±0.66x1012/l vs. 5.57±0.72x1012/l in group 2, р<0.001), platelets (93±0.97x109/l vs 186±18.3x109/l in group 2, p<0.001), total cholesterol (4.12±2.17 vs. 6.24±2.56 mmol/L in group 2, р<0.001). There were differences in the frequency of use of antiplatelet drugs: at prehospital stage acetylsalicylic acid was given to 48.9% and 77.8% of patients in groups 1 and 2, respectively (p=0.044); clopidogrel and ticagrelor were also significantly more rarely used in group 1. There was no difference in use of thrombolysis and percutaneous coronary interventions (4.4 and 53.3% vs 5.6 and 56.6% in groups 1 and 2, respectively). In group 2 greater portion of patients was given statins (68.9 vs. 77.8%, p=0.021) and angiotensin-converting enzyme inhibitors (55.6 vs. 82.2%, p=0.008). Inhospital mortality was the same in both groups (4.4%). Occurrence of complications (bleeding, pulmonary edema, cardiogenic shock), and frequency of use of intra-aortic balloon counterpulsation, temporary cardiac pacing were similar. However in group 1 greater portion of patients had ventricular tachyarrhythmias (15.6 vs 2.2% in group 2, р=0.007); the presence of cancer was the only independent predictor of their emergence in multiple logistic regression (OR 8.11 [1.11-40.83], p=0.011).Conclusions. Rates of application of myocardial reperfusion in STEMI patients with and without history of cancer were the same. Despite similar hospital mortality revealed peculiarities of STEMI course could affect long-term outcomes. Confirmation of this hypothesis requires planned prospective studies.
