Published: January 2021

In this modern era, shifting the type of product from physical to digital has been popular. As an example, a textbook that been used by students in university may be acquired in the digital form which is an e-book. Marketing promotion is not only for a textbook, yet e-book should be treated the same. Online seller in Indonesia does promotion which is price discount to attract customer. Accordingly, there are two types of price discount frames which are % form or absolute form. Both may attract customers differently. Therefore this research aimed to find the impact of discount frame and type of product on customer purchase intention. The sample number is 92 students who take management Master's Degree at Tarumanagara University and the object of this research is purchase intention. This research used experimental design 2x2 factorial. SPSS program is used to do an ANOVA analysis. The first independent variable is the discount frame with two sub-factorials which are % discount and Rp discount. The second independent variable is the type of product with two sub-factors which are textbooks and e-book. The result showed that type of product has a significant effect on customer purchase intention. There is no significant effect of the discount frame on purchase intention. The research result also showed that type of product does not moderate the relationship between discount frame and customer purchase intention.  Pada zaman modern saat ini, perkembang bentuk produk dari bentuk fisik menjadi digital semakin banyak.

Poznanie i opis krajoznawczy małej ojczyzny... oraz wzbudzenie zainteresowania uczniów regionem jako inspiracja do nauki geografii
Authors: Szubert Mariusz , Kroh Paweł
Published: January 2021

Krajoznawstwo było i jest związane z edukacją, zwłaszcza geograficzną. Krajoznawstwo w szkole utożsamiane jest głównie z wycieczkami, których celem jest poznanie regionu lub kraju ojczystego. Wzbogacanie wiedzy krajoznawczej połączone jest z kształtowaniem postawy patriotycznej. W szczególności odnosi się to małej ojczyzny, jej poznawania oraz działalności krajoznawczej na jej rzecz. Mała ojczyzna jest jednym z edukacyjnych celów szczegółowych nauczania geografii w szkole podstawowej. Temat „Moja mała ojczyzna” przewidziany jest klasie siódmej.

W publikacji przedstawiono propozycję realizacji tematu „Moja mała ojczyzna” opartego na WebQueście oraz krajoznawczej interpretacji dziedzictwa małej ojczyzny. Tok WebQuestu składa się z pięciu elementów. Trzem grupom uczniów przydzielone będą trzy zadania, których wynikiem będzie dokumentacja krajoznawcza małej ojczyzny, składająca się z opisu krajoznawczego, mapy oraz krajoznawczych opisów dziedzictwa małej ojczyzny. Jest to zadanie integrujące opis małej ojczyzny z wiedzą nie tylko z zakresu geografii, ale też innych przedmiotów np. biologii, historii, wiedzy o społeczeństwie, j. polskiego, fizyki i chemii. Połączenie zajęć lekcyjnych z krajoznawstwem wyzwala emocjonalny związek ucznia z małą ojczyzną (ojcowizną) i jej dziedzictwem przyrodniczym i kulturowym, wzbudza ciekawość, chęć poznawania świata, co przekłada się na jego aktywizowanie i kreatywność w edukacji szkolnej.

Effects of Xanthan Gum Biopolymers on Gypseous Soils Characteristics
Authors: Theyab Arwa F. , Muhauwiss Farouk M. , Alabdraba Waleed M.
Published: January 2021

Gypseous soils are problematic soils that cause large deformations in the constructions that are built on it. Therefore, many binders have been used to reduce this impact. Traditional soil binders like lime or cement have environmental problems in terms of sustainability. Thus, sustainable substances have attracted appreciable interest in recently soil enhancement. Biomaterials are being developed to enhance geotechnical engineering properties like hydraulic conductivity, strength, and slope stability of varied soil types. This study aims at evaluating the engineering characteristics of gypseous soil treated with xanthan gum biopolymer. The tests performed on three types of gypseous soil with various gypsum contents and different properties. Gypseous soils were mixed with various contents of xanthan gum with a percentage of 2, 4, and 6. The compaction results indicated that xanthan gum decreases the maximum dry density and increases the optimum moisture content. The treated gypseous soils exhibited a low collapse potential by more than 30% - 45% with xanthan gum. The direct shear results of biopolymer treated soils showed significant shear strength gains. The results of the current study imply xanthan gum biopolymer improvement as an environmentally friendly method to improve the engineering properties of gypseous soil.
Building Collaborative Data System on Top of the Operational Transformations Algorithm
Authors: Saltuk Konstantin E.
Published: January 2021

Providing users with the way to collaboratively edit shared model is the challenge of complex informational systems. The majority of existing methods require online connection between users, otherwise, users’ intentions can be lost after a certain delay. The aim of this research is to build a collaborative system that allows users to edit shared model in offline manner without losing their intentions. Firstly, commit-based system was selected as underlying data storage.
Secondly, we examined existing collaborative algorithms and selected operational transformation as the most perspective for this scenario. Thirdly, we described the way to merge commits, that stores operations, using modified operational transformation algorithm. Key features of modified operational transformation algorithm include ability to handle resolving of merge conflicts, when intentions of two users are conflicting. To implement this, we consider the set of commits branches as ordered set. As a result, we developed a version control system, that stores user’s intentions and can automatically resolve conflicts on merge. This approach can be applied to any informational system, which is able to save user’s input as the set of operations.
Limitations of Applying the Data Compression Method to the Classification of Abstracts of Publications Indexed in Scopus
Authors: Selivanova Irina V.
Published: January 2021

The paper describes the limitations of applying the method of classification of scientific texts based on data compression to all categories indicated in the ASJC classification used in the Scopus bibliographic database. It is shown that the automatic generation of learning samples for each category is a rather time-consuming process, and in some cases is impossible due to the restriction on data upload installed in Scopus and the lack of category names in the Scopus Search API. Another reason is that in many subject areas there are completely no journals and, accordingly, publications that have only one category. Application of the method to all 26 subject areas is impossible due to their vastness, as well as the initial classification of Scopus. Often in different subject areas there are terminologically close categories, which makes it difficult to classify a publication as a true area.
These findings also indicate that the classification currently used in Scopus and SciVal may not be completely reliable. For example, according to SciVal in terms of the number of publications, the category “Theoretical computer science” is in second place among all publications in the subject area “Mathematics”. The study showed that this category is one of the smallest categories, both in terms of the presence of journals and publications with only this category. Thus, many studies based on the use of publications in ASJC may have some inaccuracies.

The control system of the X-ray complex LIA-20 is based on the Tango Controls framework. Data archiving subsystem HDB++ was improved during the work for efficient storage of waveforms. PostgreSQL DBMS support as a storage was added. PostgreSQL extension “pguint” for unsigned numbers support was modified to support the binary transfer mode during this work. Performance testing of the modified “pguint” extension and the new DBMS interface was performed. This solution allowed to significantly increase the performance of HDB++, reduce the amount of data stored in the database, as well as remove restrictions on the size of the stored data.
Utilizing Curvilinear Grid for 2D Wave Field Simulation Heterogeneous Media with Topography
Authors: Titov Pavel A.
Published: January 2021

The main practical interest of geophysics is the restoration of the structure of the medium. So one can understand whether there are hydrocarbon reservoirs at depth. Studying the structure of the medium by taking numerous samples and drilling wells is a very financially and time-consuming task. Therefore, the use of mathematical modeling seems to be a good alternative. If the calculations show a result similar to the initial data of the medium, then such algorithm for restoring the medium can be applied new regions. Verification of the algorithm should be carried out on real structures of the media, but real wave field data are not provided, since they are often the subject of trade secrets. In this case, the result of this work comes to the rescue. Numerical simulation is widely used in studying the processes of wave field propagation in various complex media. One way is to discrete the domain for which the simulation is being performed, and to construct a difference scheme for further numerical implementation. This work involves the construction of a mesh with curved quadrangles, which allows good agreement with the topography of the surface. A parallel algorithm of numerical modeling based on the numerical solution of a linear 2D system of elasticity theory written in displacements using a curvilinear mesh and an explicit difference scheme is proposed. The simulation results are presented. The calculations were carried out using the resources of the SSCC SB RAS.
Simulation of 3D Wave Fields in Inhomogeneous Domain with Complex Topography Using the Lebedev Scheme
Authors: Titov Pavel A.
Published: January 2021

Numerical simulation is widely used in the study of wave fields in various media. One of the methods is to divide the domain of interest into elementary volumes and build a finite-difference scheme for numerical implementation. The work assumes that the domain can have a significant curvature of the surface, therefore, the technology of generating a mesh of curved cubes is used. This mesh provides good consistency between the discrete and physical models of the domain. A parallel algorithm is proposed for the numerical solution of a 3D linear system of elasticity theory, expressed via displacement velocities and stresses, using a curvilinear mesh and an explicit difference scheme based on the Lebedev scheme. The simulation results are presented. The calculations were carried out using the resources of the SSCC SB RAS.
Synthesis of Automatic Control Systems for Technological Processes of the Gas-Air Path of the Organic Waste Processing Plant
Authors: Shakirov Stanislav R. , Kvashnin Alexandr G. , Pisarev Artem V.
Published: January 2021

A research team from ICT SB RAS is actively developing a system to control a pilot plant for processing organic waste automatically. The pilot plant can produce thermal energy and energy carriers (solid products, e.g. bio-coal, liquid products, e.g. bio-oil, and gaseous products, i.e. synthesis gas), for example, from biomass with different chemical
composition and physical properties. The equipment can process "complex" types of waste characterized mainly by high moisture and high ash content. During tests of the pilot plant, the complexity of stabilizing the parameters of technological processes and ensuring the stability and reliability of operation of the equipment of the complex as a whole were identified. This is especially important when implementing high-temperature modes of biomass processing. In order to primarily solve these most important tasks, an automatic control system of the plant is being created.
When a system for automatic control of technological parameters of the gas-air path of the pilot-industrial plant is developed, a mathematical model that describes the dynamic characteristics of the gas and air paths under various throughput rates of the plant was used. When determining mathematical models, a two-way relationship between the gas path and air path was identified (interchannel connections).
When technologically complex real objects of control are being automated, in the inaccuracy of a priori information about the object, when the system operates in various uncertain external and internal situations, disturbing influences, a robust control method should be used. PID controllers were selected as corrective devices for stabilizing the technological parameters that characterize the operation mode of the gas-air path of the plant including pressure in the lower part and rarefaction in the upper part of the combustion chamber. The most appropriate method for determining the PID controller settings has been elected.
Synthesis and simulation of the operation of the controllers of the pressure in the lower part and rarefaction in the upper part of the combustion chamber are performed. Basing on the results of mathematical modeling, the efficiency of the controllers of the pressure in the lower part and the rarefaction in the upper part of the combustion chamber for various loads of the plant has been shown, and their stability reserves by amplitude and phase are determined. The results of mathematical modeling of the stabilization contours of the technological parameters of the gas-air path of the plant are presented for two cases: without inter-channel connections and without the account of these connections. A simulation of the joint operation of the control circuits of the gas-air path of the plant is performed. Compensators for adjacent (interchannel) connections of the gas and air paths of the plant have been developed. The advantage of the proposed automation schemes is shown.

Realizou-se uma revisão bibliográfica de caráter narrativo através da consulta de artigos científicos indexados nas principais bases de dados da literatura médica. A literatura científica descreve a infecção por Clamídia como um significativo problema de saúde pública na atualidade, até mesmo em países desenvolvidos. A associação entre a infecção prolongada pelo patógeno e a doença inflamatória pélvica e demais complicações do trato genital resulta de uma complexa fisiopatologia, envolvendo alterações morfológicas, imunológicas e no microbioma genital. A falta de informações e a inacessibilidade aos testes diagnósticos prevalecem como significativos impasses no controle da enfermidade, o que pode resultar em impactos severos na saúde reprodutiva das mulheres. O adequado rastreio e tratamento precoce da doença inflamatória pélvica são imperativos, sobretudo considerando que a mesma pode apresentar-se como uma condição insidiosa.
O papel do enfermeiro frente a violência infantil na atenção primária
Authors: Da Silva Stefany Alves , Ceribelli Carina
Published: January 2021

A violência infantil é uma realidade crescente no Brasil se tornando um grave problema de saúde pública. A atenção primária se torna o ambiente ideal para o enfrentamento dessa temática devido o vínculo entre profissional e a comunidade, tendo o enfermeiro um papel fundamental para intervir no ciclo da violência e não permitir a sua perpetuação. Entretanto, nota-se que o enfermeiro não sabe o seu papel frente esta temática, se colocando muitas vezes como incapaz de intervir frente a esses casos, portanto o objetivo deste artigo é estudar o papel do enfermeiro frente a violência e vitimização infantil na atenção primária através de revisão bibliográfica. O estudo permitiu se evidenciar três principais papeis do enfermeiro frente a esses casos na atenção primária, sendo eles: identificação dos casos, notificação compulsória e prevenção e promoção. Contudo, se evidenciou que os profissionais enfrentam muitos limites e desafios se mostrando como os principais a ausência de formação e capacitação, medo e ausência de fluxograma de apoio. Assim, se concluindo a relevância da abordagem da temática nas grades curriculares do curso de enfermagem e a necessidade de uma rede de apoio organizada e articulada para enfrentamento destes casos.

In this COVID-19 lockdown Survey Monkey study, as many as 75% of 260 respondents reported feeling fatigued. Correlation analyses suggested that feeling fatigued was significantly correlated with demographic variables and virtually every item on every scale of the survey. The demographic correlations suggested that fatigue occurred more frequently in younger participants, in males, and in those not working from home during the lockdown. The significant correlations for the scales suggested that those feeling fatigued engaged in fewer health activities including exercise and self-care; they spent more time on social media including gaming and Facebook; they engaged in less cooking and creative projects; they scored higher on the Stress Scale including worrying more about the virus and their finances; they reported feeling more isolated, lonely, bored and touch deprived; they did more snacking and napping and expressed more “cabin fever”; they had lower scores on connecting and activities at home; and they had higher scores on anxiety, depression, sleep disturbances, and PTSD scales. A regression analysis suggested that 51% of the variance in the fatigue scores was explained by the depression (37% variance), sleep disturbances (12%) and anxiety (1%) scores. These results are limited by their being self-reported data from a non-representative, cross-sectional sample. Nonetheless, they highlight the negative effects of feeling fatigued during a COVID-19 lockdown.

Introduction: A prospective study was carried out, with the aim of establishing the clinical manifestations of cholelithiasis in the population of Quito, Ecuador. Methods: During the period from January 2012 to October 2017, 534 patients were referred from different outpatient clinics of the Ecuadorian Institute of Social Security to the Batan Medical Center with the diagnosis of cholelithiasis after a clinical assessment and abdominal ultrasound, to be treated surgically. Results: Sixty-nine percent of patients were female with a male-female ratio of 1:2.21. Mean age was 44.9 years. Pain was the most common symptom in our study: 95.7%. Among these patients, pain was located in the epigastrium in 49.8%, in the right hypochondrium in 45.1% and only 0.8% had low back pain. Pain ranged from moderate and even severe. The remaining 4.3% of patients had dyspepsia or were asymptomatic. Conclusions: This finding highlights the fact that epigastric pain must be always considered as a clinical manifestation on cholelithiasis.

Introduction: Hepatitis B (HBV) and C (HCV) virus infections represent a major public health problem, with significant mortality and morbidity worldwide. The aim of this study was to determine the prevalence of HBsAg and anti-HCV antibodies, and to investigate the risk factors associated with these two infections. Patients and methods: An analytical cross-sectional study was carried out during a free screening campaign for viral hepatitis B and C organized by the University Teaching Hospital of Yaounde from 20th to 23rd August 2019. Screening for HBsAg and anti-HCV antibodies was carried out using a rapid diagnostic test (On Site HBsAg/HCV Ab Rapid Test (CTK Inc 10110 Mesa Rim Road San Diego, CA 92121 USA) in accordance with the manufacturer’s Instruction. Positive samples had a confirmatory ELISA test. A structured questionnaire was used to investigate the risk factors for viral hepatitis B and C. Results: A total of 746 participants (412 women, 334 men) were registered. The average age of the participants was 29.6 ± 15.5 years. The prevalence of HBsAg was 10.3% (men: 14.7%; women: 7%; p = 0.002). The prevalence of HCV-Ab was 4.7% (men: 6.3%; women: 3.4%; p = 0.08). Unprotected sexual intercourse (59.4%), dental care (38.7%) and scarification (37.1%) were the main factors of HBV and HCV transmission. Male sex (OR = 2.2; IC = 1.3 – 3.6; p = 0.002), lack of vaccination (OR = 3.4; IC = 1.2 – 9.6; p = 0.01), tattoos (OR = 6.6; IC = 1.4 – 30.2; p = 0.02) and close contact with an HBV-infected person (OR = 1.7; IC = 1.01 – 2.9; p = 0.04) were the factors associated with HBV transmission. Age groups ≥ 55 years (OR = 1.3; IC = 1.1 – 1.5; p < 0.0001) and [45 – 54] (OR = 1.06; IC = 1.0 – 1.1; p = 0.03) unprotected sexual intercourse (OR = 3.5; IC = 1.4 – 8.7; p = 0.003), dental care (OR = 2.3; IC = 1.1 – 4.5; p = 0.02) were associated with HCV infection. Conclusion: The prevalences of HBsAg and HCV-Ab are high in this population. Unprotected sexual intercourse, dental care and scarification were the most common risk factors.

Avaliou-se o padrão de distribuição espacial dos novos casos de tuberculose (TB) entre 2000 e 2005, na zona urbana do município de Arapiraca, Estado de Alagoas. Para a análise do padrão pontual dos eventos considerados (aleatoriedade, regularidade ou aglomerados), foi aplicado o modelo de Aleatoriedade Espacial Completa (Complete Spatial Randomness-CSR), através da função K que considera os efeitos de segunda ordem. A função K aplicada às localizações geográficas das ocorrências dos casos de TB mostrou que o padrão da distribuição dos casos de tuberculose não é aleatório, indicando agrupamentos em todos os anos do período estudado. O método Kernel ratificou a presença de aglomeração espacial dos casos, assim como permitiu detectar onde os eventos estavam concentrados. As áreas Centro – Nordeste e Centro-Sudeste destacam-se, sendo a primeira com maior intensidade.

O governo brasileiro decidiu, após detalhado diagnóstico, instalar uma grande infraestrutura de sensores que pudesse fornecer dados confiáveis da região amazônica. Esta infraestrutura é conhecida como Sistema de Vigilância da Amazônia – SIVAM. Entre os sensores previstos para entrar em operação em 2002, estão três aeronaves de sensoriamento remoto, na qual encontram-se instaladas um radar de abertura sintética (SAR), um imageador multispectral (MSS) e um sensor ótico e infravermelho (OIS). O presente estudo analisou a sinergia entre os dados SAR- Radar de Abertura Sintética e Landsat 7 ETM+ quanto a capacidade de distinção de alvos. Foram analisadas bandas individuais e compostas de ambos os sensores e os resultados foram avaliados de forma qualitativa e quantitativa. Os resultados indicaram que os dados SAR foram eficazes na discriminação de vários tipos de cobertura, especialmente nas polarizações XL, LHH e LHV em relação as imagens do satélite Landsat TM.

A análise quantitativa das drenagens tem sido uma prática sistematizada há pelo menos meio século. A relação destas com o relevo, entretanto, vem sendo aplicada desde os primórdios dos estudos geográficos/naturalistas. No intuito de contribuir para análises do relevo, foi aplicado o Índice de Hack (IH) nos canais principais de 3 drenagens situadas na Zona Transversal. Nos rios Paraíba do Norte, Goiana e Capibaribe foram identificadas áreas anômalas de 1ª e 2ª ordem em seus perfis longitudinais, apresentando a existência de uma ruptura de patamar principal entre as cotas de 200 e 300 metros, bem como a existência de, ao menos, duas superfícies topográficas na porção central e norte da Zona Transversal, entretanto tais rupturas não são verificadas na porção sul deste setor. Estes dados nos permitem postular um basculamento do Macrodomo da Borborema no setor supracitado. Por fim verificou-se que este método é eficaz na identificação e quantificação de anomalias e nos estudos de evolução do relevo.
