Research of requirement management features in the field of project management in a full-cycle engineering company
Authors: Kudrevatykh Vladimir V. 
Published: August 2020

Introduction. Organizational development and practice of the project management system implementation is of particular interest to engineering companies that implement complex and multi-stage design and construction projects having a complex structure, a large number of stakeholders and a high degree of result individualization. In this case, a situation often arises when processes are formalized, which means that a certain list of regulatory documents are developed in which project contributors, their activities, authority and responsibility, a sequence of actions to be performed, templates of project documents, etc. are defined, but in practice these requirements are not fulfilled or not fulfilled in full. The research problem is that approaches to the formation of a project management system do not offer a universal mechanism applied to monitor the compliance with project management requirements established by inhouse regulatory documents. As a result, project contributors resist such requirements in some companies. The subject of the study is the development of a tool designated for the monitoring of compliance with regulatory documents in the field of project management in a full-cycle engineering company.
Materials and methods. The method of process modeling and reengineering, statistical analysis, and the requirements management methodology were applied.
Results. Features of project management in engineering companies are outlined. Research results obtained in terms of adapting the requirement management methodology and engineering project quality are analyzed. The target scheme that applies to project management quality control and project audit processes was performed. The toolkit for the project management quality control was developed and a list of indicators was formulated. The analysis of statistics on cases of failure to comply with project management quality indicators and underlying reasons is conducted.
Conclusions. The project management quality control toolkit, proposed in the article, allows to analyze the compliance of project contributors with the requirements applied to project management processes formalized in a company and to increase the efficiency of various types of projects.

Published: September 2020

OBJECTIVE
Weight loss diets may reduce serum urate (SU) by lowering insulin resistance while providing cardiometabolic benefits, something urate-lowering drugs have not shown in trials. We aimed to examine the effects of weight loss diets on SU and cardiometabolic risk factors.

RESEARCH DESIGN AND METHODS
This secondary study of the Dietary Intervention Randomized Controlled Trial (DIRECT) used stored samples from 235 participants with moderate obesity randomly assigned to low-fat, restricted-calorie (n = 85); Mediterranean, restricted-calorie (n = 76); or low-carbohydrate, non–restricted-calorie (n = 74) diets. We examined SU changes at 6 and 24 months overall and among those with hyperuricemia (SU ≥416 μmol/L), a relevant subgroup at risk for gout.

RESULTS
Among all participants, average SU decreases were 48 μmol/L at 6 months and 18 μmol/L at 24 months, with no differences between diets (P &gt; 0.05). Body weight, HDL cholesterol (HDL-C), total cholesterol:HDL-C ratio, triglycerides, and insulin concentrations also improved in all three groups (P &lt; 0.05 at 6 months). Adjusting for covariates, changes in weight and fasting plasma insulin concentrations remained associated with SU changes (P &lt; 0.05). SU reductions among those with hyperuricemia were 113, 119, and 143 μmol/L at 6 months for low-fat, Mediterranean, and low-carbohydrate diets (all P for within-group comparison &lt; 0.001; P &gt; 0.05 for between-group comparisons) and 65, 77, and 83 μmol/L, respectively, at 24 months (all P for within-group comparison &lt; 0.01; P &gt; 0.05 for between-group comparisons).

CONCLUSIONS
Nonpurine-focused weight loss diets may simultaneously improve SU and cardiovascular risk factors likely mediated by reducing adiposity and insulin resistance. These dietary options could provide personalized pathways to suit patient comorbidity and preferences for adherence.

OBJECTIVE
We evaluated the association between diabetic retinopathy stages and lower-extremity arterial disease (LEAD), its prognostic value, and the influence of potential contributors to this relationship in a prospective cohort of patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS
Diabetic retinopathy was staged at baseline as absent, nonproliferative, or proliferative. A Cox regression model was fitted in order to compute the hazard ratio (HR) (95% CI) for major LEAD (lower-limb amputation or revascularization) during follow-up by baseline retinopathy stages. The retinopathy-LEAD association was assessed in subgroups by age, sex, diabetes duration, HbA1c, systolic blood pressure, diabetic kidney disease, smoking, and macrovascular disease at baseline. The performance of retinopathy in stratifying LEAD risk was assessed by using the C statistic, integrated discrimination improvement (IDI), and net reclassification improvement (NRI).

RESULTS
Among 1,320 participants without a history of LEAD at baseline, 94 (7.1%) developed a major LEAD during a 7.1-year median follow-up (incidence rate 9.6 per 1,000 person-years [95% CI 7.8–11.7]). The LEAD incidence rate (per 1,000 person-years) increased as retinopathy worsened: it was 5.5 (95% CI 3.9–7.8) in participants in whom retinopathy was absent, 14.6 (11.1–19.3) in those with nonproliferative retinopathy, and 20.1 (11.1–36.3) in those with proliferative retinopathy. Nonproliferative retinopathy (adjusted HR 2.31 [95% CI 1.43–3.81], P = 0.0006) and proliferative retinopathy (3.14 [1.40–6.15], P = 0.007) remained associated with major LEAD. No heterogeneity was observed across subgroups. Retinopathy enhanced the C statistic (+0.023 [95% CI 0.003–0.044], P = 0.02), IDI (0.209 [0.130–0.321], P &lt; 0.001), and NRI (0.562 [0.382–0.799], P &lt; 0.001) values for risk of LEAD, beyond traditional risk factors.

CONCLUSIONS
An independent dose-response relationship was identified between diabetic retinopathy stages and major LEAD. Retinopathy yielded incremental prognostic information for stratifying risk of LEAD, suggesting its usefulness as a predictor of LEAD.

Published: August 2020

The density functional theory (DFT) method was used to study the adsorption of acidic CO2 molecule on the oxide clusters (MgO)n , (n = 2, 4, 6, 8, 9 and 12). Basis sets, 6–311 G, 6–311G (d) and 6–311G (2d) were employed in order to test the effect on adsorption structures and binding energies. Both and adsorption sites have been considered. Our previous calculation DFT energies have been achieved for the (MgO)n, (CaO)n, (n = 1–4, 6, 8, 9, and 12 clusters), [WJERT, 2019, Vol.5, Issue 1, 328-341]. The present work investigates the adsorption properties (e.g., adsorption energies, geometries and HOMO and LUMO molecular orbitals) of a single CO2 molecule. The results show that the CO2 molecule / (MgO)n clusters prefer to adsorb as [Mg surf – with one acidic sites, while the interaction with surface basic sites, carbonate species consequently may occur. The HOMO and LUMO interaction between CO2 and MgO cluster models were also studied. Furthermore, such nanostructures systems can be potential candidates for practical applications of capturing CO2 from hot exhaust gases.

Published: August 2020

In the last decades, in a large part of developed countries, a strong investment was made in the construction of infrastructures, namely bridges. However, the state of the road bridges changes with age due to several factors, which cause a progressive worsening of their degradation and a consequent decrease in the strength of the structure, if measures are not implemented that somehow cancel or counteract these effects, being of great importance correct management of the conservation status of these works of art.

Good managerial performance is essential especially in view of the limited financial resources or under the bias of their best use. Through computerized bridge management systems or “Bridge Management Systems”, deterioration rates are introduced through algorithms that may vary according to the type of structure, its location, constituent material, or even the environment in which it is inserted, providing important subsidies for decision making. Deterioration Models that may be deterministic, such as least squares-based regression, or probabilistic, such as Markov chains are considered in this review paper. Other methodologies use artificial intelligence processes (natural algorithms or neural networks). The objective of the article is to describe the existing techniques, evaluating their limitations, specificities, and potential. Based on the awareness of the importance of deterioration models, it is possible to verify the fundamental role of routine inspections for the management of construction parks. The inspection of bridges can develop beyond the simple verification of the condition of the works in the present, providing subsidies for a better understanding of the behavior of these works over time. In the same way, inspection methods could provide for the collection of data relevant to the manager's knowledge containing information about possible decisive agents in the deterioration rates.

In the long term, the development and inclusion of explanatory variables in bridge management could bring great benefits to the industry. The development of mechanistic models used in conjunction with deterioration models could provide accurate results in predicting the state of condition. In addition, the development of these models would provide benefits in understanding the mechanisms of deterioration of the bridge components.

The aim of this research is to comprehend in details how revitalization and development of railway infrastructure on the Trans-Sumatera line in Sumatera Island. The main problem in this research is that the use of railways in Sumatera Island is neither sustainable nor in all provinces. This research is both meta-analytical, by exploring the existing journals, and factual as a phenomenon in the utilization of spoor width that happens in the world today. It is completed by parameter or performance indicators as for benchmarking with other countries. From the result of this research, the data shows that almost 60 percent of existing railway tracks around the world have been installed with standard gauge of 1,435 mm and have been international standard. The benefit of this study is that the leaders or decision makers can take it into account to support the future transportation in Sumatera Island which must be oriented to bigger, faster, safer, cleaner, cheaper, affordable, and leisure. To keep exploiting the existing railway or track can be done by developing construction equipment of track gauge adjuster to change the wheel gauge from 1,435 mm to 1,067 mm. Subsequently re-gauging is done in stages, changing the track gauge from narrow gauge of 1,067 mm to standard gauge of 1,435 mm.

The majority of farmers with small scale enterprises are still facing a capital shortage primarily rice farming. Capital constraints caused farmers must perform farm activities with a limited input. Limited input causing the output and the revenue generated is not optimal. Food security and energy credits are one of the credit which intends to help especially rice farmers. By the low interest rate, this credit is expected to help farmers for improving the use of inputs and increasing the output and revenue. The aims of study are to evaluate the use of credit on production activities and to analyze the increase in rice farming profits before and after the credits. Research methods used in this research were descriptive analysis, multiple regression analysis, and different test (t-test). The results showed that the rice farmers used KKPE for 53% for rice farming which included the purchase of equipment and farm machinery, production inputs and labor wage. An increase in rice farming profits, but not affected by the credit, and from the t-test result that there was no difference profits before and after credit.

Published: August 2020

Search engine optimization (SEO), which is currently actively used by the majority of pharmaceutical companies all over the world, is one of the most relevant digital marketing technologies. The features of the SEO in pharmaceutical companies as one of the modern tools of digital marketing have been considered in the article.Most of the companies, which operate in the natural sciences, are several years behind in development from other industries, due to the low level of SEO strategy application. As a result, the marketing budgets of pharmaceutical companies are focused on maintaining traditional classical approaches in the field of marketing. This bias in the budget arises mainly from the underestimation of the role of the SEO strategy in the organization’s activities by the majority of pharmaceutical companies. Companies should clearly understand how significant is the impact of digitalization on their activity in modern conditions. SEO is much broader than using search queries and meta tags. Due to implementing digital tools, it is possible to create “social signals” for attracting a new target audience.It has been noted in the article that search algorithms, developed by search platforms, change very often, and it is necessary to constantly monitor and improve them. Moreover, SEO is required to help people to find the content that best matches their intended goal, rather than to misinform them by showing inappropriate pages with matched search keywords in search results.Competition among the largest companies is constantly increasing in the global pharmaceutical market, and the use of digital marketing tools, such as SEO, will allow companies to change radically the situation. As a result of the research, recommendations for the effective use of SEO as one of the digital marketing tools in the business of pharmaceutical companies have been proposed. Finally, the conclusions about the increasing the role of digital marketing in modern conditions have been made.

The regularities showing the development of information exchange in the virtual space have been examined, electronic document management in the organization using information systems has been considered. It has been shown that the intellectualization of information systems is based on a powerful mathematical apparatus that provides work with texts by computer programs, based on the creation of models that include patterns necessary for the design of modern information search systems, as well as systems for automatic classification and analysis of texts.A document flow model based on a number of mathematical regularities, numerical methods of multivariate integration, the theory of mixed Queuing networks has been proposed. This model allows you to evaluate the multivariate integration of devices of electronic document management systems (EDMS), contributes to the formation of statistical data on document processing, provides with minimal time costs the formation of information flows in electronic document management systems, has a convenient user interface for object interaction programs. This model, based on the definition of a set of options for data transmission channels, a set of options for data collection equipment EDMS, a set of options for data processing equipment, a set of end devices of the EDMS communication environment, allows you to analyse the functionality of electronic document management systems.The proposed EDMS model shows that a number of functions of complex document management in an organization can be automated and optimized based on mathematical methods, which will reduce the time of document preparation, its routing and processing. Document management of the organization, using this EDMS, ensures optimization of information flows in the organization, contributes to the formation of important management decisions, taking into account all risk factors.

El presente trabajo de investigación identifica el nivel socioeconómico y los proyectos de vida de estudiantes de quinto de secundaria y la correlación de las dos variables, considerando la muestra con un total de 335 estudiantes de 4 instituciones educativas de la UGEL Arequipa Norte. Asimismo, la investigación determina la existencia de la correlación significativa baja e inversa entre estas dos variables.
En la metodología se determina que es una investigación de tipo correlacional, con una población de 2017 estudiantes de instituciones educativas con una meta de atención mayor de 500 estudiantes y atención de los tres niveles de la EBR, pertenecientes a la UGEL Arequipa Norte. Siendo una muestra probabilística estratificada seleccionada por fórmula, considerando 4 instituciones educativas aplicándose dos instrumentos a cada uno de los 335 estudiantes entre damas y varones.
Se concluye de acuerdo a los resultados obtenidos que, a menor nivel socioeconómico se tiene mejor establecido su proyecto de vida y que a mayor nivel socioeconómico se tiene menor nivel en su proyecto de vida.
Considerando los resultados y la preocupación de que un porcentaje mayoritario (y si fuera posible total al cien por ciento), la autora propone una guía especializada para la elaboración de Proyecto de vida, como parte de la investigación y aporte para las instituciones donde se aplicó la investigación. La guía va dirigida al docente, tomando como tema principal los pasos y orientaciones para ayudar a los estudiantes en la elaboración de su proyecto de vida, brindando ayuda y orientación pertinente desde las Instituciones educativas.
EL IMPACTO DE LAS OBLIGACIONES TRIBUTARIAS ELECTRÓNICAS EN LA FORMALIZACIÓN DE LAS MICRO Y PEQUEÑAS EMPRESAS PERUANAS
Authors: Tuesta Bardalez Segundo Eloy , Espinoza Poves Jenny Luz 
Published: August 2020

El presente artículo analiza el impacto de las obligaciones tributarias electrónicas en la formalización de las micro y pequeñas empresas (MYPE) peruanas en un periodo transversal, años 2008 al 2017, para lo cual basado en el método analítico – sintético y en técnicas de revisión documental, estadística descriptiva y el análisis de regresión lineal, se analiza datos primarios que han sido publicados por distintas entidades del sector público del Estado peruano que interactúan en el ámbito económico y la gestión empresarial. Los resultados evidencian que las sucesivas reformas normativas y la gestión tributaria ejercida por la administración tributaria (SUNAT), aún no han logrado un impacto positivo con la implementación y uso de las tecnologías de información y comunicación en las obligaciones tributarias electrónicas, impacto que se evidencia en una baja presión tributaria del sistema y una estructura de base tributaria de alto riesgo que aún no utiliza medios electrónicos para el cumplimiento de las obligaciones tributarias. Al momento de estudiar la relación entre la recaudación del impuesto y la base tributaria, se observa que esta es débil, lo cual indica que es poco predecible el sistema actual. Además, es necesario mencionar que lo que se recauda respecto a tributos del sector empresarial peruano tiene una brecha riesgosa del 0.6% de contribuyentes denominados PRICOS. Asimismo, identifica importantes brechas de informalidad tributaria en las MYPE peruanas.
