Mechanisms of management of Shipbuilding cluster systems
Zaporozhets, I. M. Mechanisms of management of Shipbuilding cluster systems / I. M. Zaporozhets, N. V. Fateev, B. Yu. Kozyr // Innovative development of the economy: global trends and national features : collective monograph / edited by J. Žukovskis, K. Shaposhnykov. – Lithuania : Publishing House “Baltija Publishing”, 2018. – P. 563–574.An effective tool for ensuring the competitiveness of shipbuilding enterprises is the application of a cluster approach. The shipbuilding cluster systems are functionally distributed logistics networks that evolve both nationally and internationally. The essence and features of the shipbuilding cluster systems in the work have been considered. The mechanisms of the organization of shipbuilding clusters are suggested as well as the indicators for evaluating the efficiency of their operation. The schemes of interaction of enterprises participating in the shipbuilding cluster have been developed. In this case, models and means of logistic management are used. For the logistics center, the functions of logistics support and the tasks of creating and maintaining a common information space of the cluster system are defined. The analysis of the system of planning and accounting units in shipbuilding is carried out, the scheme of decomposition for the organizational structure of the cluster is substantiated. It was proposed to use the corridor-scale network diagrams when planning work in a cluster. The scheme of interaction of the system of budgets and business processes at different levels of decomposition is substantiated

Автоматизация анализа измерительных приборов
В статті розглянуто моделі вимірювальних пристроїв як об’єкту проектування та їх нормовані метрологічні характеристики. Викладено матричний апарат аналізу вимірювальних пристроїв, похибок перетворення. Наведено приклади використання визначників в автоматизованому аналітичному аналізі електричних кіл.The design of measuring devices is based on the previous experience and supposes development of structural, functional and schematic diagrams. Transfer and error equations are used to describe them. The instrumentation unlike other technical devices have normalized metrological features established in the international, state and industry standards. The most important features are transfer function and measurement error.
Since the measurement devices general design and optimization methodology are not sufficiently developed, the conformance evaluation of the designed device is done by analyzing the number of options, modifications and re-analysis to obtain the optimal solution. Therefore, the automation of the analysis process becomes particularly relevant.
The most promising features have matrix equations through the possibility of encoding variables on their location and further displacement according to the designed algorithms. Based on determinant properties the established error equations in a matrix form have a possibility of an accurate representation of the total error regardless of the size of the component errors of the structural scheme. Also in matrix form the equations with complex coefficients are presented.В статье рассмотрены модели измерительных устройств как объектов проектирования и их нормированные метрологические характеристики.

Operando Laboratory X-ray Absorption Spectroscopy and UV–Vis Study of Pt/TiO<sub>2</sub> Photocatalysts during Photodeposition and Hydrogen Evolution Reactions
Photocatalytic hydrogen (H2) production is a promising route for alternative energetics. Understanding structure–activity relationships is a crucial step towards the rational design of photocatalysts, which requires the application of operando spectroscopy under relevant working conditions. We performed an operando investigation on a catalytic system during the photodeposition of Pt on TiO2 and photostimulated H2 production, using simultaneous laboratory X-ray absorption spectroscopy (XAS), UV–Vis spectroscopy, and mass spectrometry. XAS showed a progressive increase in Pt fluorescence for Pt deposited on TiO2 for over an hour, which is correlated with the signal of the produced H2. The final Pt/TiO2 catalyst contained Pt(0) particles. The electronic features corresponding to the Pt4+ species in the UV–Vis spectrum of the solution disappear as soon as UV radiation is applied in the presence of formic acid, which acts as a hole scavenger, resulting in the presence of Pt(0) particles in solution
Multimorbidity in Pediatric Dermatology: Clinical Case
Background. Nowadays, dermatoses with mixed clinical picture and resistant to classical management become more common. The presence of various genetic disorders typical for most chronic dermatoses may indicate possible combination of several nosologies.Clinical Case Description. The article presents the clinical case of multimorbid condition in 10 years old patient who has nucleotide variants in CARD14 and EXPH5 genes. Mutations in CARD14 gene are typical for patients with type 2 psoriasis and pityriasis rubra pilaris (autosomal dominant type), while mutations in EXPH5 gene are typical for patients with non-specific epidermolysis bullosa (autosomal recessive type). Mutation in the TGM1 gene that is described in patients with congenital ichthyosis (autosomal recessive type), pathogenic mutations in KRT74 gene typical for ectodermal dysplasia, hypotrichosis and uncombable hair syndrome, and mutations in the KRT86 gene typical for monilethrix were also revealed. Medical history taking and histological examination as well as clinical data evaluating are crucial for correct diagnosis. They allow to understand the absence of the such manifestations in relatives and reveal various pathological processes in the epidermis. Molecular genetic testing with new generation sequencing (NGS) helps to finally establish the diagnosis and determine the further tactics for patient management.Conclusion. Multidisciplinary approach and use of high-technology methods of examination and treatment (such as molecular genetic testing and biological therapy) are required for final diagnosis in severe forms of chronic dermatosis resistant to treatment and for decision on correct tactics for the further management of such patients
Psoriasis Comorbidities in Childhood
Psoriasis is multifactorial systemic disease characterized by excessive hyperkeratosis due to impaired keratinocytes proliferation and differentiation. This disease often manifests in childhood and it is usually associated with the development of comorbid conditions some of which are combined by the term «psoriatic march» (obesity, metabolic syndrome, etc.). The course of psoriasis and related comorbidities in children has several specific features that determine topicality of studying all the aspects of clinical diagnosis and prevention in childhood. The article summarizes recent ideas on the prevalence, pathogenesis features and early diagnosis of comorbid diseases in children with psoriasis
In Situ X-ray Absorption Spectroscopy Cells for High Pressure Homogeneous Catalysis
We have designed, built, and tested two cells for in situ and, potentially, operando X-ray absorption spectroscopy experiments in transmission and fluorescence modes. The cells were developed for high-pressure and high-temperature conditions to study the catalytic processes under relevant industrial conditions. Operation of the cells was tested for Ru and Rh-based homogeneous and heterogeneous catalytic systems. Using synchrotron-based in situ X-ray absorption spectroscopy we tracked the evolution of active metal species during catalytic reactions. Our setup proved that it was capable to investigate liquid-state homogeneous and heterogenous systems under elevated temperatures, high pressures of reactive gasses, and in the presence of corrosive reagents
