В развитие Полимодельного квалиметрического метода системной оптимизации объектов морской техники рассмотрена математическая модель и методика инвариантной оценки качества объектов исследовательского проектирования и их систем. Обобщены свойства Полимодельного квалиметрического метода, сравнительные свойства алгоритмов агрегирования показателей качества и предложена методика инвариантной оценки качества и эффективности, а также системной оптимизации объектов морской техники и морской инфраструктуры как объектов исследовательского проектирования. Разработанные основные положения методики на примере объекта морской техники класса «Корабль» позволяют количественно оценивать качество, эффективность, конкурентную способность и перспективность развития в условиях лавинообразного роста сложности современных объектов морской техники, ужесточения требований к качеству процессов их создания и эксплуатации на всех этапах жизненного цикла. Это позволяет на принципиально новом уровне решать задачи концептуального, исследовательского и конструкторско-технологического обоснования эффективных и оптимальных проектных и эксплуатационных решений за счет специфики инвариантного моделирования объектов. In the development of a multi-Model qualimetric method for system optimization of marine engineering objects, a mathematical model and a method for invariant assessment of the quality of research design objects and their systems are considered. The properties of the Polymodel qualimetric method, comparative properties of algorithms for aggregating quality indicators are generalized, and a method for invariant assessment of quality and efficiency, as well as system optimization of marine engineering and marine infrastructure objects as research design objects is proposed. The developed basic provisions of the methodology on the example of a Ship-class marine equipment object allow us to quantify the quality, efficiency, competitive ability and prospects of development in the conditions of an avalanche of increasing complexity of modern marine equipment objects, stricter requirements for the quality of their creation and operation processes at all stages of the life cycle. This allows us to solve the problems of conceptual, research and design-technological justification of effective and optimal design and operational solutions at a fundamentally new level due to the specifics of invariant object modeling.

Лавинообразный рост сложности современных объектов морской техники, морских интегрированных автоматизированных систем в защищенном исполнении, ужесточение требований к качеству процессов их создания и эксплуатации на всех этапах жизненного цикла обуславливают острую необходимость поиска инвариантных решений по их модельному представлению, а также технологии анализа, синтеза, оптимизации проектных решений. Более того, по количественному обоснованию конкурентной способности, путей их технологического развития. В результате проведения ряда поисковых и прикладных исследований обоснована целесообразность и возможность инвариантного модельного представления качества современных структурно сложных систем, а также мониторинга, прогнозирования и управления их качеством. Это позволяет на принципиально новом уровне решать задачи концептуального, исследовательского и конструкторско-технологического обоснования эффективных и оптимальных проектных и эксплуатационных решений за счет специфики инвариантного моделирования объектов. The avalanche-like increase in the complexity of modern marine engineering objects, marine integrated automated systems in protected execution, and stricter requirements for the quality of their creation and operation processes at all stages of the life cycle make it necessary to search for invariant solutions for their model representation, as well as technologies for analysis, synthesis, and optimization of design solutions. Moreover, the quantitative justification of competitive ability and ways of their technological development. As a result of a number of search and applied research, the feasibility and possibility of invariant model representation of the quality of modern structurally complex systems, as well as monitoring, forecasting and quality management are proved. This allows us to solve the problems of conceptual, research and design-technological justification of effective and optimal design and operational solutions at a fundamentally new level due to the specifics of invariant object modeling.

BackgroundWorldwide, 340 million people are affected by depression, with high comorbid, social and economic costs.AimsTo identify potential predictors of effect in prevention programmes.MethodA meta-analysis was made of 69 programmes to reduce depression or depressive symptoms.ResultsThe weighted mean effect size of 0.22 was effective for different age groups and different levels of risk, and in reducing risk factors and depressive or psychiatric symptoms. Programmes with larger effect sizes were multi-component, included competence techniques, had more than eight sessions, had sessions 60–90 min long, had a high quality of research design and were delivered by a health care provider in targeted programmes. Older people benefited from social support, whereas behavioural methods were detrimental.ConclusionsAn 11% improvement in depressive symptoms can be achieved through prevention programmes. Single trial evaluations should ensure high quality of the research design and detailed reporting of results and potential predictors.

Nursing in Italy is achieving a higher academic status as a result of decades of efforts in scientific knowledge development. Beginning in the 1980s, Italian nurses, supported by researchers from allied disciplines, have begun to design and implement research at the local, regional, and national level. This study is the first effort ever made to identify the main characteristics of Italian nursing research published in Italian journals. The review covers 14 years (1983–1997). Overall, 240 studies from 11 journals, research reports from books, and several conference proceedings have been considered. Inclusion criteria were based on quality of research design, considering components such as sampling, sample size, and method of data analysis. Each article was analyzed according to an interpretive scheme focusing on method of analysis, scientific merit, and authorship.Of the 240 studies reviewed, journal articles selected from ten Italian journals accounted for 175 (73%), or the majority, of reviewed sources. Sixty-five (26%) research reports complete the remaining number. The major areas of research identified include nursing practice (43%), nursing education (6%), nursing administration and professional issues (34%), and knowledge and perceptions in society and nursing (17%). The majority of the research studies utilized survey models (47%), including several retrospective and longitudinal studies, followed by exploratory or descriptive (36%) and quasi-experimental (17%) designs. Many reports failed to identify the method of sampling used in the research design. However, of those that did, convenience samples were most often used. Random sampling was rarely reported. The majority of studies employed only descriptive statistics (i.e., frequency distribution, central tendency, variability, contingency tables, and correlation). Only few studies made use of advanced statistics for testing hypotheses (parametric and non-parametric tests) among which only a low percentage cited reliability testing. In 42% of the studies, the authors were represented by a group of nurses. Nurses and physicians worked together to author another 30% of the studies. The remaining studies were authored by either individual nurses (24%) or nurses and nonmedical professionals (4%). Much of the reviewed research has been carried out by nurses who have little or no research training.

The article discusses the experience of teaching and conducting spirometry of general practitioners as part of the RESPECT study (RESearch on the PrEvalence and the diagnosis of COPD and its Tobacco-related aetiology). A total of 33 trained in spirometry general practitioners performed a study of 3119 patients. Quality criteria met 84.1% of spirometric studies. The analysis of the most common mistakes made by doctors during the forced expiratory maneuver is included. The most frequent errors were expiration exhalation of less than 6s (54%), non-maximal effort throughout the test and lack of reproducibility (11.3%). Independent predictors of poor spirogram quality were male gender, obstruction (FEV1 /FVC<0.7), and the center where the study was performed. The number of good-quality spirograms ranged from 96.1% (95% CI 83.2–110.4) to 59.8% (95% CI 49.6–71.4) depending on the center. Subsequently, an analysis of the reasons behind the poor quality of research in individual centers was conducted and the identified shortcomings were eliminated. The poor quality of the spirograms was associated either with the errors of the doctors who undertook the study or with the technical malfunctions of the spirometer.

Indriyani et al, (2013) stated that many students had dificulty in understanding the generic structure of analytical exposition text. Therefore, the present study tried to investigate the correlation between students understanding in writing generic structure of analytical exposition and the quality of students’ writing in second grade of senior hight school. Grounded in explanatory correlational research design by Creswell (2011), this study conducted over two weeks in one of senior high school in Indramayu. Close-ended questionnaire and writing test were instruments to collect the data and it was analyzed  by using SPSS 22. The statistical calculation from students understanding in writing generic stucture of the text and writing test indicated that the value of tcount was 3.23 and the value of ttable was 0.361. It can be concluded that the hypothesis was accepted because tcount 3.23 > ttable 0.361. The finding reveal that there was middle correlation or middle prediction in students understanding of generic structure of analytical exposition and students writing quality with the score 0,52.
