Designing an integrated model based on the indicators Quality and Earned Value for risk management in Information Technology Projects

There are two effective factors on Information Technology (IT) projects risk including quality and earned value so that by controlling these two factors and their increased level in IT projects, the corresponding risk can be decreased. Therefore in present study, an integrated model was designed based on quality and earned value indicators for risk management in IT projects on a new and efficient approach. The proposed algorithm included the steps such as preparing a list of several indicators of quality and earned value through experts and professionals’ comments and literature review, integrating the indicators quality and earned value and creating new indicators, modeling Fuzzy Delphi integrated approach and multivariate regression to determine the significant and effective indicators on projects risk, modeling network analysis process to determine efficacy of the significant and effective indicators on projects risk. The results indicated that quality indicators, earned value indicators and integrated quality and earned value indicators are effective on IT projects with different efficacies. Three key effective indicators on risk management of IT projects include experienced, knowledgeable individuals with high and updated skills in order to enhance project scheduling performance, suitable governance by the responsible, accountable and executive people after the project in order to decrease deviation of schedule and get a specific plan from beginning to end of the project to reduce nonconformities regarding the schedule.

Special Aspects of Specialist Training for Military Industrial Complex (Incentives Conception Integral Quality Indicator and Practical Recommendations)

The paper studies special concepts of so-called mentally structured approach to training the elite specialists of technical profile to be employed by the military industrial complex (MIC). Training of MIC-oriented specialists concerns specialties related to its special status of a dual technology “industrial locomotive”. This, in turn, requires specialized teaching aids, which in their harmonized body are capable to provide training the generalists (multi-discipline specialists) to meet a number of specific requirements imposed by this status. One of the features of mentally structured approach that provides the maximum efficiency of training the MIC technical elite is a conceptual statement that it is not only a user or a student (the subjects of the cognitive process) who needs to be fitted in the specialty content of a particular subject matter. The syllabus itself (i.e. the objects of a subject matter) also needs to be finetuned or adapted to psychophysiological capabilities of users (students) in accordance with entitative functioning principles of memory and thinking. In other words, the concept of mentally structured presentation of information materials is that they should not be a projection of subject matter logics only, but also a projection of logics of mental (psychophysiological) capability of users or students being subjects of cognitive process. Stated differently, the bridge needs to be built from two harmoniously augmenting each other sides, both from the side of human mental capabilities and from the side of content complexity of the subject matter studied. For this purpose, a special analysis of the operation aspects of the human brain functional systems has been conducted. It was found that functional asymmetry of cerebral hemyspheres has a fractal-quantum logical structure for processing information arriving at the brain input. Dextrocerebral structural components form, primarily, a logical structure of so-called mental fractals. Mental fractals are semantic frameworks or functional-behavioral frames which repeat themselves on various levels of mental activity being loosely connected to particularities of subject matter. Mental fractals in the essence of their content have subject invariant or intransitive nature and in their majority correspond to what definition. At the same time, sinistrocerebral structural components form, primarily, a logical structure of strictly subject-oriented content which correspond to how definition. It was also found that in order to increase the efficiency of perception and processing of the information flow arriving at the input of the brain it is expedient to present educational texts of subject oriented content filling subject-invariant fractals or semantic frameworks in quantum form. In other words, educational texts should be split into so-called info-quantums, parameters of which should be appropriate in their scale to informative characteristics of psycho-quantums inherent to various kinds of memory or associated cogitation mechanisms. Within this framework, the content of the studied subject matter (learning discipline) or information obtained (from internet, for example) has been already considered not only as a source of strictly professional knowledge and skills a specialist needs, but also as the specialized methodological aids that purposefully form students' ability to think literally (using objective laws of memory and cogitation). The latter, in turn, enables us to process information arriving at the input of the brain with maximum efficiency from the standpoint of its expected final result or given objective function.

Estimation of Economic Security Level of Regions in Ukraine

The research paper includes the review of evaluation approaches targeted at estimation of economic security level of regions in Ukraine. Authors present the results of the analysis of economic security conducted using two methods. The first applied method enabled to identify the most significant factors of economic security. The second one allowed to rank regions of Ukraine in accordance to the level of economic security. The achieved results were used as a basis to work out the ways to improve Ukraine's regional policy. Critical state of Ukraine's economy throughout the last years resulted in the increasing role of regions in resolving social and economic issues including such important ones as guaranteeing economic security. Nowadays a new economic background for creation more advanced approaches to economic security management on regional level. The estimation of the achieved level of economic security takes a major place among the managerial functions. However, existing method of evaluation based on aggregated indexes and integral indicators calculation allows neither to make a full enough assumption on economic security of a region nor conduct administration of these processes. The official methods of state economic security estimation consists of diverse indicators and is not practically used due to its complexity. These methods point out the following spheres: social, demographic and food security. Adapting the system of indicators used to estimate the level of state economic security to regional level, we suggest that the level and quality of life index should be considered as major one that characterizes the economic security level of a region. According to the encyclopedia of sociology (2) the term 'quality of life' unites such elements as the quality of material and cultural needs satisfaction, financing the personal development, as well as labour market development, level of income, consumption quality, quality of food and clothing, accommodation comfort, education, health care and service quality, the state of environment, structure of leisure time activities and the extent of social needs satisfaction, etc.. Aligning the quality and level of life indexes towards state's average can be the ground for regional economic security management and may allow to adjust regional social and economic policy aimed at territorial development. The integral indicator of level and quality of life may consider all aspects of regional development that directly influence the indicators of economic security on the regional level. Consequently, we consider the elaboration of methods for estimation of regional economic security level to be a highly important issue. Such economists as S. Ayvozyan, V. Bogomolov, Z. Varnalia, A. Bozzhenikov, S. Glaz'yev, O. Granberg, E. Libanova, G. Kozachenko, S. Kazantsev, V. Sen'chagov, O. Snipko and others contributed in resolving the outlined question. In spite of this, the search of efficient method for regional economic security level estimation remains to be the subject of precise scientific study. The carried out research was targeted at establishing a scientific rationale for usage of the mentioned methods used to assess the regional economic security level. The practical side of the study is focused on the importance of factor analysis usage. Method In our view, the level and quality of life should be presented as a multitude of events that occur in social and economic system of a region that can be estimated with particular index. Considering the question in such a way it is essentially important to identify the pull points to scheme the management process of social and economic development. The pull points are the spheres of social and economic process that impose significant impact on formation of economic security in a region. It can be visualized with diagram of a surface, peaks of

PSYCHOSOMATIC FEATURES AND DEPRESSION LEVEL IN CHRONIC HEART FAILURE IN PATIENTS WITH ARTERIAL HYPERTENSION AND ISCHEMIC HEART DISEASES

Objective: to study the levels of depression, quality of life, personal and reactive anxiety in patients with chronic heart failure with hypertension and coronary heart disease. Material and methods. We examined 105 patients with coronary artery disease and hypertension with the manifestation of I-IV heart failure of functional classes according to the classification of the New York Heart Association. The level of depression was determined by the Beck Depression Inventory, the level of life quality was studied using the NAIF questionnaire (New Assessment and Information form to Measure Quality of life by P. Y. Hugenholtz and R. A. Erdman, 1995), personal and reactive anxiety was evaluated using Spielberg Hanina scale. The statistical analysis was performed using nonparametric tests: T-criteria of Mann-Whitney test, Spearman's rank correlation method, the data were processed with the program «Statistica», 6.0. Results. 39 patients (37.2 %) observed no depressive symptoms, 66 patients (62.8 %) detected depression of various degrees. 25 patients (41 %) observed mild depression, 26 (34.5 %) - moderate, 11 (18 %) - expressed, 4 people (6.5 %) - severe. Patients who had hypertension II-III and angina of the functional classes II and III more often suffered from depression, as well as patients with a combination of coronary heart disease and hypertension. The integral component of life quality was significantly reduced in patients with CHF FC I (73.8 ± 3.5 %), moderately reduced in patients with class II (62 ± 3.6%), significantly reduced in patients with FC III (44.2 ± 3.8%) and dramatically reduced in patients with IV FC (23.4 ± 3.8%). According to the nosological reasons, the integral indicator of life quality was lower in the patients who suffered hypertension II-III, angina FC II-III, as well as in those with a combination of hypertension and coronary heart disease. The level of reactive anxiety in all the groups of the patients did not exceed 45 points, that is, remained moderate and the reactive anxiety FC did not depend on chronic heart failure, angina and severity of arterial hypertension. At the same time we noticed a high rate of personal anxiety in the patients with FC II and CHF III in the patients with angina FC II-III, hypertension II-III and combination of angina and hypertension. Conclusion. 62.8 % patients with chronic heart failure revealed depressive disorders; cognitive-affective symptoms were prevalent in the patients with classes I and II of heart failure, somatic manifestations of depression - in the patients with FC III and IV of heart failure. Depressive disorders were associated with female sex (68 % women and 32 % men), age over 50 and the severity of somatic illness. The level of life quality decreases with increasing severity of CHF FC and somatic illness. The level of reactive anxiety in all the groups of the patients with chronic heart failure is moderate, the level of personal anxiety is high and is associated with the severity of heart failure and somatic illness, possibly because of the individual characteristics of a person and the influence of their medical condition.
