Determining the parameters of a local coordinate system with a non-standard longitude of the central meridian. Analysis of existing methods
Authors: Vinogradov A.V.
Published: July 2020

Processing the results of topographic and geodetic works is performed in local coordinate systems. The parameters of the local coordinate systems were established on the basis of SK-42 or SK-63 systems. At present, it is necessary to set new communication parameters with coordinate systems SK-95 and GSK-2011. In many MCSs, the central meridians do not coincide with the origin, and the coordinates of the starting points were obtained from the catalogs of the preliminary calculation geodetic network. To establish the new communication parameters, it is necessary to determine the longitude of the central meridian MCS in SK-95 and GSK-2011 systems. To find the errors in calculating the longitude of the central meridian, MCS the models were constructed with different positions of the central meridian relative to the origin. The longitude was calculated using well-known and new formulas and methods. Errors in calculating the longitude of the MSC are systematic. An increase in the calculation volume does not exclude the influence of systematic errors, reaching 4ʺ. For some lines, they make 8ʺ.

Authors: Trubina L.K. , Nikolaeva O.N.
Published: July 2020

The high level of environment pollution is specific to urbanized territories. The efficient solution of city ecological problems requires considering urban environment as a dynamic system and taking its development over time and space into account. This can be achieved through a complex analysis of time and space dynamics of pollutants in accordance with natural conditions and city infrastructure. The study determines an approach to the environmental assessment of the urbanized territory based on geoinformation analysis and 3D cartographic modelling time and space dynamics of pollutants spreading in the urban environment. The approach to assessing it, taking into account the patterns of pollution dissemination is substantiated. The logical sequence of integrating heterogeneous environmental data for pollution distribution modelling is offered. The digital relief and terrain models of Novosibirsk city are formed. The environmental database of Novosibirsk city is developed. The city area zoning by composite index regarding environmental risk is given. A 3D model of pollution dissemination is developed.

Published: July 2020

Arranging effective state protection of historical and cultural heritage objects requires developing modern methods of identifying archaeological sites and determining their boundaries. To solve this task, an algorithm of interdisciplinary research based on the analysis of multispectral data obtained with unmanned aerial vehicles is proposed. To search for areas of the surface-transformed and substituted cultural layer, it is proposed to use a processing method based on the two-dimensional discrete wavelet transform. Using the Shannon–Kotelnikov wavelet function to study the medieval Kushman settlement of Uchkakar enabled assessing the preservation of the cultural layer in various parts of the settlement. The correctness of the proposed interpretation is confirmed by the data of geophysical studies, soil drilling and materials of archaeological excavations. Complex application of multispectral aerial photography, geophysics and soil investigation made it possible to obtain reliable cartographic information on the boundaries of the archaeological sites and the preservation of their cultural layer in a short time. The effectiveness of the algorithm is that each successive method verifies the previously obtained data and at the same time supplements the information on the archaeological sites.

Published: July 2020

In the machining of metal cutting, cutting tools are the main things that must be considered. Using improper cutting parameters can cause damage to the cutting tool. The damage is Built-Up Edge (BUE). The situation is undesirable in the metal cutting process because it can interfere with machining, and the surface roughness value of the workpiece becomes higher. This study aimed to determine the effect of cutting speed on BUE that occurred and the cutting strength caused. Five cutting speed variants are used. Observation of the BUE process is done visually, whereas to determine the size of BUE using a digital microscope. If a cutting tool occurs BUE, then the cutting process is stopped, and measurements are made. This study uses variations in cutting speed consisting of cutting speed 141, 142, 148, 157, 163, and 169 m/min, and depth of cut 0.4 mm. From the results of the study were obtained that the biggest feeding force is at cutting speed 141 m/min at 347 N, and the largest cutting force value is 239 N with the dimension of BUE length: 1.56 mm, width: 1.35 mm, high: 0.56mm.

Published: July 2020

Background/Aim. Chronic low back pain syndrome (CLBPS) is the most common cause of functional disability and loss of working ability in developed countries. Some research shows that neuropathic pain (NP) is present in almost 50% of patients with CLPBS. The aim of this study was to determine the characteristics of NP and its impact on quality of life (QoL) in patients with CLBPS. Methods. Patients were tested using three questionnaires for NP: Pain Detect Questionnaire, Leeds Assessment of Neuropathic Symptoms and Signs, and Douleur Neuropathique 4 questions. Thirty-two patients diagnosed with NP based on current clinical criteria and with positive results for NP on all three NP questionnaires formed an experimental group. A control group consisted of 32 patients with CLBPS who did not fulfill clinical criteria for NP and were negative for NP on all three questionnaires. Hamilton depression and anxiety rating scales (Ham-D and Ham-A, respectively) and Short Form (SF)-36 questionnaire were also applied. Results. According to magnetic resonance imaging (MRI), disc herniation was typically detected in the experimental group, while degenerative changes were commonly found in the control group. Patients from the experimental group had significantly greater intensity of pain, pain radiation in the legs, and the pain was usually presented as episodes of sudden attacks with mild pain between them. The most distinctive features of NP were allodynia, electric shock sensation, and hypoesthesia to prick. Patients from the experimental group also had significantly higher depression and anxiety scores, as well as worse QoL compared to the control group, especially in mental domains. Predictors of worse QoL in the patients with CLBPS were a higher level of anxiety and depression. Conclusion. The presence of allodynia, electric shock-like sensations, and hypoesthesia to prick in patients with CLBPS suggest NP. CLBPS patients with NP had worse scores in mental domains of QoL compared to CLPBS patients without NP.

Published: July 2020

Introduction. Hemangiopericytoma is a rare tumour derived from the pericytes, contractile spindle cells that surround the capillaries and postcapillary venules. The tumour is found equally among males and females. Case report. We reported a case of a 63-year-old female who presented a giant painful mass on her right shoulder that occurred one year before admission. Limited range of motion and a sense of tingling along the affected arm was present also. An irregular, oval-shaped mass, dark red in colour, with signs of necrosis, was 14 cm in maximum diameter. Routine laboratory analysis showed results within the range of referenced values. Lung X-ray and ultrasonographic examination of the abdomen showed no signs of secondary tumour deposits, and no osteomuscular lesions in the affected region. Ultrasonographic examination of the neck and right axillary region showed no signs of regional metastases. The surgical excision of the entire tumour was performed, with the associated subcutaneous tissue and a part of fascia underneath. Results of the histopathological analysis confirmed the diagnosis of hemangiopericytoma. The specimen showed no signs or elements of the neoplastic tissue on the edges of the resection lines. Three years after the operation, there were no signs of tumour relapses, regional or systemic metastases. Conclusion. Considering that there are no official clinical guides and protocols for hemangiopericytoma management, as well as the occurrence of cutaneous and subcutaneous heman-giopericytomas is exceptionally rare, more extensive research in this field and more described cases are needed to gain a better understanding of the issue.

There is a common assumption in the literature and policymakers that migrant remittances have an essential role in improving the welfare of migrant households in the regions of origin. Payments play the same position in economic development as foreign direct investment and other capital flows. This study observes international and internal remittances in Indonesia that are being made to contribute to assessing the impact of payments on household welfare. Using longitudinal data from Indonesia Family Life Survey (IFLS) from 2000 until 2007 on wave 3 and 4, the study will observe the impact of the development of remittance income on the household accumulated asset as a measure of well-being between recipients and non-recipients. This research uses propensity score matching (PSM) method and difference-in-difference (DID) to measure the revenue impact of remittances on household assets and compare them to non-remittance households. It was found that there are significant differences between the well-being of recipients with non-recipient remittances households.

With help from both domestic and international markets, ASEAN countries are able to catch-up withthe latest economic development if they can sustain high economic growth for a long-period of time. To doso, the resources available in countries such as capital and labors should fully be utilized up to theoptimum level. The capital itself can be in many forms such as investment. Since most of the ASEANcountries are categorized as developing countries, the reliance on foreign direct investment (FDI) as asource of growth is highly needed as it helps the economy to step on a higher stage of economic developmentvia the roles of foreign experts and technological transfer. In ensuring a higher level of investment, there isa need to ensure a high level of intellectual property protection since it assists in promoting invention,innovation and new business development. In opposite, lacking in protection might discourage foreigninvestors to invest in the countries, thus limiting the ability of the countries to grow further. Therefore, theaim of this paper is to examine whether strong intellectual property protection will really help in attractingmore foreign investors to invest in ASEAN-5 countries. Using annual data from 2007 to 2016, panel dataestimation using random effect is employed. It was found that the ASEAN-5 countries should strengthentheir intellectual property protection in order to stimulate higher foreign investments. Nevertheless, inbetween copyright and patents, copyrights protection gives significant effect to the FDI inflows relative tothe latter one. It indicates that the countries are slowly moving out from the production-based economy andcatching-up towards a digital economy.

In this study, phytochemical screening, antioxidant activity as well as phenolic content in the leaves,twigs and barks of Brucea javanica (L.) were determined using standard phytochemical screeningmethod, DPPH radical scavenging assay and Folin-Ciocalteu reagent method, respectively. Methanolicextracts of these different plant parts were prepared by maceration method. Phytochemical screeningrevealed the presence of flavonoids, terpenoids and tannins in all plant parts. This test also revealed thepresence of alkaloids and saponins in all plant parts except they were absent in the twigs and barks parts,respectively. On the other hand, steroids was absent in all plant parts. DPPH method was used toevaluate the antioxidant properties of the plant parts by measuring the absorbance at 517 nm. Theantioxidant activity was then compared with standard ascorbic acid. Among all parts, methanolic extractof leaves of Brucea javanica (L.) exhibited the highest antioxidant activity at the concentration of 100ppm with 86.19 ± 0.20% inhibition which was comparable with standard ascorbic acid with 97.62 ±0.13% inhibition at the same concentration. The IC50 value of the methanolic extract of leaves was 54.52± 0.16 ppm while the other parts were more than 100 ppm. All plant parts showed IC50 value higher thanthe standard ascorbic acid which recorded IC50 of 9.04 ± 0.09 ppm. The methanolic extract of the leavesalso exhibited the highest total phenolic content which was 105.58 ± 0.21 mg GAE/g extract compared tothe other parts. This result correlated well with the higher antioxidant activity exhibited by themethanolic extract of the leaves. Thus, the leaves part of methanolic extract of Brucea javanica (L.)exhibited the highest antioxidant activity compared to the other plant parts.

Aspects of consumption are becoming increasingly important as the current approach fails to solve manycollective socio-economic phenomena that lead to poverty, hunger and unemployment. There is no doubtthat the current approach is either in the form of concepts, principles, theories or models that have beenused to analyse and understand the discipline of consumption in theory and practice. However, the currentapproach which is based on ‘tasawwur’ and Western epistemology are not suitable to be applied to theculture of the East, especially the Muslim community because of the differences in background beliefs,culture and environment. This reality highlighted the importance of Islamic approach. However, theexisting of Islamic approach is smaller compared to its conventional counterparts. It justifies building anew approach that reflects on ‘tasawwur’, epistemology and the ontology of Islam.

From the literature, the entrance of multinationalcompanies might affect the small companies surrounding them, including UniShop which is a smallenterprise. Thus, the research examined student loyalty in purchasing at UniShop by distributingquestionnaires to the students of the university. The researchers used proportionate stratified randomsampling to generalize the finding across all semester students in the university. The findings showed thatbrand image and service quality played an important role in student loyalty. Students were the maincustomers of a university shop, contributed most of the shop’s business sustainability, and generate indirectincome to the university. In order to maintain student loyalty, UniShop has to take some initiatives includingto increase the scale of products, focuses on student-centered services, improve the shop layout, and sellexclusive university merchandise to increase the student's self-belonging to the university products.

Upgrading and patching is a method to strengthen the host and virtualisation devices from malware. Inthe deployment to different entity’s clients, different scenarios are faced to support their business process.A host and virtual machine (VM) are dependent on each other to provide high efficiency. A good design ofvirtual resources in a physical host can maintain the host’s efficiency. If the host is to be upgraded orpatched, then the relationship with VM needs to be explored to avoid missing or malfunctioning of certainapplication on the host or VM. A relationship how to check whether the application scenario is workingas expected is not being derived. This paper will discuss scenarios that we face and how it can beconverted into taxonomy to provide a strategic approach when upgrading a specific item. With that, ananalogy can be based on how the application scenario can be established as a model and converted intotaxonomy for troubleshooting when execution is facing an error.

Humans need to eat good and balanced nutritious diet that provides calories for energy requirements andnutrients for proper growth, repair and maintenance of the body tissue. Today, busy lifestyle habitsdrastically changed the pattern of eating where students are more likely to have irregular meal times andthe cost of food may be expensive for them. Therefore, this study is conducted to find the minimum costthat satisfies the daily nutrient requirements. A linear programming (LP) model and goal programming(GP) model are formulated where the objective function is the total cost of food. Food prices werecollected from selected cafés in UiTM Perlis and the recommended daily nutrient intakes of 19-29 yearsold, male and female were obtained from the Ministry of Health Malaysia. The sample used in thisresearch consists of 10 most frequently consumed food items as decision variables. QM for Windows V5was used to determine minimum cost that satisfies the nutritional requirements. LP results, the minimumcost for male students is RM9.88 and for female students is RM9.10. Based on the GP results, the cost isRM9.00 for both male and female students. It is evident from the results that GP has achieved theminimum cost and the food basket for male students consists of 410g of rice, 140g of chicken, 42.9g ofbroccoli and 252.7g of mushroom. Meanwhile, the food basket for female students consists of 429g ofrice, 113.4g of chicken, 37.44g of broccoli and 321.3g of mushroom.
