'The hand belongs to someone': a therapist perspective on patient compliance
Authors: Van Stormbroek Kirsty
Published: February 2021

Background: Compliance is considered to be a central element of effective health systems. In terms of rehabilitation, both nonattendanceand non-compliance of patients with hand injuries in South Africa have been reported. This study explored how occupationaltherapists practicing in the field of hand therapy, understand compliance and its perceived barriers and supports.Methods: A qualitative descriptive research design was employed. Nine occupational therapists who routinely treat patients with haveconditions were purposively sampled. In-depth interviews were conducted, transcribed and inductive thematic analysis undertaken.Results: Therapists' understanding of compliance demonstrated elements of consensus and difference. Four themes captured participants'views of barriers and supports: compliance is enabled when a powerful collaboration exists between the client and the therapist. For thisto be possible, the therapist needs to understand the life and times of an injured hand, co-constructing therapy on the foundation ofunderstanding the patient as an occupational being. Powerful collaboration is further enabled by effective communication for collaboration,and lastly the characteristics of systems and services that work hold power to hinder or enhance compliance.Conclusion: Results suggest that collaborative co-authoring of the hand rehabilitation process is central to enabling compliance.Therapists require a robust understanding of the person they are treating and the complex context in which the person participates.Accessible communication, effective education and enabling systems and services are also vital. Furthermore, the way in which occupationaltherapists conceptualise compliance matters. Critical reflection is necessary to interrogate the philosophical assumptions that underpinthe terminology that occupational therapists choose and how power is navigated in relationships with patients with hand injuries.

Authors: Christine Pincela da Costa Caroline , Soares de Lima Nayane , da Silva Santos Rodrigo , Adamski da Silva Reis Angela
Published: February 2021

The VEGF-A gene encodes a homonymous protein, responsible for regulating angiogenesis and vascular permeability. In addition, in the central nervous system, it acts as a neurotrophic factor, stimulating neurogenesis and cell survival. VEGF-A rs28357093 is located in the promoter region of the gene. There are few studies with this polymorphism, with no reports on the consequences. However, it is in a regulatory region, important for the control of gene transcription, and may influence gene and protein expression. In this document, we share our protocol for amplification and enzymatic digestion for this SNP, using the PCR-RFLP technique and silver staining for genotyping analysis.

Published: February 2021

Recent advances in next generation sequencing (NGS) technologies have paved the way for augmented genomic research. From the conventional microarray analysis to the current NGS-based whole transcriptome pipelines, there have been significant advances on how differentially expressed genes (DEGs) are identified. With several bioinformatics pipelines in use, inferring the candidate DEGs prove to be a cumbersome approach as one may have to reach consensus in analysing the results from various pipelines. To ensure this, we have benchmarked the well-known Cufflinks-Cuffdiff pipeline on a set of datasets and present it in the form of a protocol for the research community interested in performing downstream analysis of whole transcriptome shotgun sequencing. Keywords: RNA-Seq, Transcriptome analysis, bioinformatics pipeline, differentially expressed genes

The main directions of development of seismic monitoring systems in underground mineral mining are analyzed. The expediency of passive registration of natural seismic activity is proved, which provides prediction of geodynamic phenomena by locating the centers of seismic events and determining their energy level. The methods of active seismic monitoring (seismic tomography, cross-borehole survey, recording of seismic signal from a rock-breaking tool) are technically more difficult to implement. The promising methods for processing seismic information are geolocation, neural network technology, cluster analysis, and integration with numerical stress–strain analysis of and changes in acoustic properties of rock mass. The configuration of the platform developed at VNIMI and the GITS seismic monitoring system, which includes from 6 to 12 three-component seismic sensors installed permanently in wells or on pedestals, is described. The detailed layouts of seismic sensors at recording points and in gateways in extraction panels are presented. The main technical characteristics of GITS are given: the signal frequency range is 0.1–1000 Hz, the minimum recorded signal level is 0.01 mV. The main test data of GITS in Komsomolskaya mine of Vorkutaugol are described: the average annual levels of seismic activity and energy of seismic events are found to be relatively stable; the relationship between seismic event with the maximum total energy and the alternating increment in the relative criterion is defined, and the local increase in the average energy of a single event in time from the moment the main roof caving is identified. Aimed to substantiate the regional and local prediction criteria of probability of geodynamic events caused by confining pressure, VNIMI implements integrated research in mines in different regions.

The authors analyze connection between the rock mass water content due to surface water (precipitation, snow melting and water bodies) and rock bursts in mines. The seismological monitoring performed from 2001 at the surroundings of the Apatite Circus and Rasvumchorr Plateau apatite deposits identified fluctuation of the general seismic background from year to year and seasonably. For these deposits, increased water content of rocks is seen as a natural trigger for rock mass seismicity during intensive rains and snow melting. The 15 year-long seismic monitoring of the apatite deposits under study has revealed regularity in a seasonal growth of seismicity during snow melting and precipitations, mainly in spring months. Particularities of geodynamical event occurrence allow a conclusion on the ultimately stress state of the upper earth’s crust in whole in the deposits’ vicinities. Reactivation of tectonic disturbances and weakened rock mass zones occurring due to relief of normal compression during infiltration can be a potential principal mechanism of seismic activation of the rock mass during the increased water content periods. The origin of the events observed is linked with the dynamic release of ultimate rock mass stresses when geomechanical conditions change under the action of hydrostatic pressure on tectonically disturbed zones. The authors make a conclusion on necessity to apply the revealed regularities of impact of natural factors on rockburst hazard when planning mining operations and performing geomechanical monitoring.

The Discriminatory Legalism Strategy and Hate Speech Cases in Poland. The Role of the Commissioner for Human Rights in Fighting Discrimination
Authors: Demczuk Agnieszka Elżbieta
Published: February 2021

The regress of liberal democracy in the world has been progressing for years and the number of countries with the full democracy index is decreasing [Economist Intelligence Unit 2018, 2019; Freedom House 2018]. One of the serious threats to the rule of law and the human rights in modern democracy has become discriminatory legalism which is both strategy and weapon [Weyland 2013]. In order to weaken or marginalize the opposition and “rebellious” citizens, public authorities apply discriminatory legal instruments and democratic rules depending on who they are concerned with. Public authorities do this because of political views and use exclusion rhetoric, a language of hatred, stigmatizing all “strangers”, at last use hate speech on the Internet and beyond. The weaponization of hate speech is a convenient instrument for political struggle and the fight against inconvenient opponents. Hate speech is also used by far-right and nationalist organizations in the public sphere, which operate in an atmosphere of consent to their radical behaviour. Political hate speech plays an important role in the discriminatory legal strategy. Poland is included in the group of countries with flawed democracy (Article 7(1) TEU since 2017). The authorities introduced changes in law (which were defied as the “Frankensteinisation of legislation” by the Parliamentary Assembly of Council of Europe [PACE] in 2019), democratic institutions and the prosecution applies a discriminatory legalism strategy. This problem is highlighted by the current Commissioner for Human Rights which is an independent institution in the field of fighting hate speech (except a few independent media and NGOs informing about the hate speech phenomenon). Many of hate speech cases are discontinued or not taken up by the prosecution. The numbers of cases of hate speech and hate incidents are increasing but the Polish authorities use the underreporting mechanism. The Ombudsman warns that only 5% of cases are reported to the police. The language of hatred and contempt used by the authorities in Poland has become the weaponization in the fight against citizens as political opponents: LGBT+ community, refugees, political opponents, independent judges and others.

Accessory spleen torsion: a rare cause of acute abdominal pain
Authors: Bowles Madison
Published: February 2021

Accessory spleens, which are also known as a splenunculus or a splenule, are a benign developmental anomaly in which nodules of splenic tissue exist separate to the main body of the spleen. It is a reasonably common phenomenon which is present in approximately 10-30% of the population, however they only infrequently become symptomatic. Torsion of an accessory spleen is a rare cause of abdominal pain with few cases reported in the literature, most commonly in the paediatric population. Without treatment, torsion can lead to significant complications including haemorrhagic shock, peritonitis or rupture. The rarity portends a diagnostic challenge and thus a high index of suspicion is crucial for attaining a prompt diagnosis and timely management. This case gives an account of a 43-year-old female who presented with abdominal pain secondary to a torted accessory spleen.

Published: February 2021

This paper analyzes and determines the decision variables and constraints, establishes the EECM-ARAMA model to analyze and research coal price forecasts. Firstly, we first confirm the influencing factors. Then, we conduct correlation coefficient tests on price and various factors, and get the strength of the correlation between each factor and price. The second is to establish a coal price prediction model. Firstly, we use the EEMD method to transform the original price series into a stable time series, and then formulate three ARIMA models by comparing the size of the influencing factors and the parameter estimation results. After testing, we finally choose the ARIMA 03 model to predict the next 31 days, 35 Weekly and 36-month coal prices. Finally, we combine the models and ideas of the above issues to obtain factors that affect coal price changes and related price prediction models, and combine experience to give some feasible policy recommendations.

As an important part of the supply chain, commercial banks are necessary to pay attention to various risk points to the supply chain of the financing subject. Avoiding and reducing the risk of supply chain finance business are the top priority issues required to be solved for commercial banks.
ON SMOOTHNESS OF SOLUTION OF ONE NONLOCAL PROBLEM FOR HYPERBOLIC EQUATION
Authors: Kirichek V. A.
Published: February 2021

In this paper we consider a nonlocal problem with integral boundary condition for hyperbolic equation. The conditions of the problem contain derivatives of the first order with respect to both x and t,, which can be interpreted as an elastic fixation of the right end rod in the presence of a certain damper, and since the conditions also contain integral of the desired solution, this condition is nonlocal. It is known that problems with nonlocal integral conditions are non-self-adjoint and, therefore, the study of solvability encounters difficulties that are not characteristic of self-adjoint problems. Additional difficulties arise also due to the fact that one of the conditions is dynamic. The attention of the article is focused on studying thesmoothness of the solution of the nonlocal problem. The concept of a generalized solution is introduced, and the existence of second-order derivatives and their belonging to the space L2 are proved. The proof is basedon apriori estimates obtained in this work.

Published: February 2021

The Russian Federation’s fulfillment of its obligations as a social state provides for a fairly wide range of measures, including incentives for certain types of activities. Legislative looseness of the Institute of benefits for insurance premiums causes errors in the enforcement of certain norms of legislation on taxes and fees and requires scientific understanding. The article examines the scientific positions on the issues of tax benefits and benefits for insurance premiums, and identifies their main differences. Special author’s attention is paid to judicial practice on the implementation of article 56 and article 427 of the Tax Сode of the Russian Federation. The conclusion that it is necessary to include in the Tax Сode of the Russian Federation an article regulating benefits for insurance premiums is substantiated. A scientific assumption is made about the possibility of extending the rules and principles related to tax benefits to the Institute of reduced rates of insurance premiums.

The promotion of cassava as a staple and food security crop is widespread in Africa,Kenya included. Overreliance on cassava as a sole energy provider could lead to malnutrition. Consumption of high hydro-cyanide levels from cassava products could lead to health complications for consumers.This study sought to establish the contribution of cassava consumption to nutrition in Migori County.A cross-sectional survey was carried out and data collected on households’cassava production and consumption practices. Two hundred and fifty-three households were randomly selected and household farming heads interviewed in West Kanyamkago, Orango Central and Kamgundho locations as areas where cassava is predominantly grown. Seven cassava flour samples of different cassava varieties grown in the area were obtained from farmers.Analyses were done to determine the moisture, cyanide and protein contents on flour and cooked stiff porridge (ugali). Results indicated that 99.1% of the households were farming. They highly depended on sale of farm and livestock produce as income.Ninety four percent of the households consumed cassava,of which 88.4% produced cassava on their farms. The most preferred cassava variety was ‘Rateng’.The main cassava products consumed were ugali(stiff porridge)and porridge. Majority of the households (95%) never consumed cassava leaves and were not aware that cassava leaves could be consumed.The cyanide level on average on dry flours was 53.23mg/kg while on consumed cooked ugali was13.44mg/kg. These levels were above the maximum limit of 10mg/kg recommended by WHO.Low average protein levels of <0.5g/100g were observed in the cooked ugali. This could pose a danger of protein energy malnutrition if no other sources are consumed by the household members.Cassava farming households in the study area require support to promote growth of low cyanide varieties in order to reduce intake.

Human resource management divisions are such critical areas of both the public and private sectors that can regulate a country's socio-economic and financial status via generating and manipulating skilled workforces for all possible revenue sectors. Nominal GDP with purchasing power parity (PPP) of a nation is directly interlinked with the human resource policies. For such a developing country as Bangladesh, human resource development and management issues are often very challenging, when the government has to face the demands of a vast population with the least amount of resources. In this research, different highest to the lowest revenue sectors of our country have analyzed depending on the opinions of the HRM experts and the data records of the government, where a correlative study have preferred with the government invest to revenue scale for sector wise human resource development over twenty years. In all aspects, the correlation was significant, because only the highest emphasized sectors of the Govt. could ensure better subsidiaries, higher investments and phenomenal human resource management such as- agriculture and textiles than the inferior looking sectors namely- healthcare and socio-economic. Comprehensive factorial analysis has taken place in this research which can help to figure out the concerns and prospects of the HRM sectors means skilful training facility, health insurance, gender discrimination, education level, corruption, public private partnerships, government policies and so on. A business friendly environment and job sector comparative education and training systems can ensure sound HRM in Bangladesh with proper and cutting edge integrative policies.
Mycotoxins in Maize and Implications on Food Security: A Review
Authors: Chukwudi U.P. , Kutu F.R. , Mavengahama S.
Published: February 2021

Mycotoxin poisoning is not restricted to pets and farm animals, it causes diseases and death in humans. Mycotoxin producing fungi are common components of the epiphytic and endophytic microflora in crops resulting in natural crop contamination in the field and during storage. The level of contamination is influenced by the genetics of the plant and fungi, management practices and prevailing climatic conditions. The Global movement of maize products necessitates global as well as country-specific surveys on mycotoxin occurrence. Significant differences in the concentrations of deoxynivalenol, fumonisins and zearalenone were found in commercial maize for the seven years under review but no significant difference was detected between white and yellow maize types with regards to fumonisins and zearalenone concentrations. The absence of Aflatoxins, Ochratoxin-A, T2-toxin and HT-2 toxin in the commercial maize samples from 2010/2011 to 2016/2017 seasons is a food safety advantage for South Africa maize producers.

Published: February 2021

Background: Japanese quail, similar to domestic chicken, is equally sensitive and susceptible to stress but limited literatures are available so far. Therefore, this study was aimed to investigate the effect of feed withdrawal stress on the changes in reproductive tissues, steroid hormones and gene expression in Japanese quail. Methods: Forty two quail hens (10weeks) were individually caged and subjected to feed withdrawal for a period of 10 days without water restriction. Six birds each were sacrificed on 0, 1, 2, 4, 6, 8 and 10 day. The reduction in oviduct weight and serum concentration of steroid hormones was evaluated. The quantitative expression of IGF-1, Caspase-2, Survivin and HSP-70 genes were performed in ovarian follicles using real-time PCR. Result: No hierarchial follicles were detected after day 6. The ovary and oviduct weight was significantly reduced on day 2 and 4 respectively. The serum estrogen and progesterone were declined significantly when corticosterone was increased from day 1.

In Pakistan, Knemidocoptes pilae (scaly face mite) mite infestation is a frequently seen parasitic issue in budgerigars. This mite specifically causes extensive damage to featherless areas of cere and legs. This study was conducted to evaluate the topical efficacy of 1% ivermectin and 10% fipronil against two groups of Knemidocoptes pilae infested budgerigars. Fipronil and ivermectin spot on were topically administered on days 0, 7 and 14, on dorsal surface of neck in their respective group. It was concluded that ivermectin readily initiates the healing response after first application as compared to the fipronil and both drugs clear the Knemidocoptic infestation and lesions by 21 days following first treatment.

Background: The seed yield of chickpea can be improved by selection of superior genotypes on the basis of different yield and yield component traits. These genotypes exclusively utilize in breeding programs. Yield is a complex trait which is affected by several factors, hence, a well-known technique known as principal component analysis was used to identify and minimize the number of traits for effective selection. To obtain efficient recombinants, the identified component traits need to be combined from diverse parents through recombination breeding followed by selection of transgressive segregants. Hence, the present study is envisaged to measure the genetic diversity among genotypes of chickpea. Methods: The experimental material comprised of 40 chickpea genotypes evaluated in randomized block design with three replications. The experimental unit was four rows per plot with 4 m length and spacing between row to row and plant to plant maintained as 30 x 10 cm. NPK (20:40:00) fertilizers was applied as basal doses. The data were recorded for each genotype on nine quantitative traits as per standard methods. Descriptive statistics and PCA analysis was performed by using the statistical package SPSS 16.0 version and cluster analysis was done using the Wards method of hierarchical clustering technique. Result: Out of nine PCs only three PCs exhibited more than 1.0 Eigen value and showed about 73.4% variability. PC1 contributed 28.6% of the total variation and correlated with days to flowering, days to maturity, plant height, first pod height, seeds per pod and number of pods per plant while PC2 explained 21.00% of the total variation and dominated by plant height, first pod height and seed yield. PC3 explained an additional 13.00% of the total variation and dominated by primary branches per plant. Genotype commonly found in more PC, were BG 4016, IPCB 2015-165, IPC 2011-247, GNG2459 and RKG 19-4. Hierarchical clustering technique grouped 40 genotypes into two main clusters (A and B) and nine sub clusters. The present investigation depicted that the chickpea germplasm displayed considerable genetic diversity for most of the traits under consideration.

The research about Echinoderms diversity in Cibuaya Beach Ujung Genteng, West Java has been conducted from February to July 2019. It aimed to know diversity index of Echinoderms. It used belt transect method with three stations in the intertidal zone. Sampling technique used purposive sampling. The observation data are included primary data (the number of phylum Echinoderm’s species in the transect) and environmental data (pH, salinity, temperature, depth, current strength, and substrate). The population in this study was all species of Echinoderms found in the intertidal zone. The sample in this study was the species of Echinoderms found in the area of the station. Based on the result, the study obtained 8 species of Echinoderms, consisted of 3 classesand classified into 5 orders, 5 families, and 6 genera. The diversity index is classified as low with the average value of 0.62. The evenness index is classified as low with the average value of 0.37. The dominance index is classified as moderate with the average value of 0.67. Keywords: diversity, echinoderms, cibuaya beach, Ophiuroidea, Echinoidea, Holothuroidea.

La enfermedad causada por el coronavirus 2 asociado al síndrome respiratorio agudo grave (SARS-CoV-2), se conoce formalmente como Coronavirus Disease 2019 (COVID-19). Su principal foco de infección es el sistema respiratorio, pero se han descrito también manifestaciones neurológicas. Objetivo: Describir las manifestaciones neurológicas en pacientes con COVID-19 en el hospital Edgardo Rebagliati Martins. Material y Métodos: Estudio observacional, descriptivo, transversal, empleando los registros médicos electrónicos de los pacientes hospitalizados con COVID -19 y dados de alta durante el periodo Abril-Agosto 2020. Se clasificaron a los pacientes como portadores de manifestaciones neurológicas del sistema nervioso central y periférico. Resultados: De 1122 pacientes, 354 (31,5%) presentaron alguna manifestación neurológica, en tanto que 26,9% mostraron síntomas del sistema nervioso central (SNC) y 8,4% del sistema nervioso periféricos (SNP). El síntoma más frecuente del SNC fue cefalea (19,7%) y como patologías: encefalopatía (4,7%), el ataque cerebrovascular isquémico(2,7%), crisis epiléptica sintomática aguda (0,5%), hemorragia cerebral (0,4%), encefalitis (0,2%). Dentro de las manifestaciones del SNP predominaron mialgia (3,4%), anosmia (3,1%), disgeusia (2,9%) y, como patologías, rabdomiólisis (1,3%) y polirradiculoneuropatía aguda (0,3%). La tasa de letalidad alcanzó el 32,7% con un OR de 1,4. Conclusiones: Pacientes con infección por SARS-CoV-2 pueden presentar sintomatología neurológica como la descrita en el presente estudio, y sus manifestaciones deben ser consideradas en la atención oportuna e integral de los casos.

The problem relevance of socio-cultural adaptation of international students in the Siberian region is determined by several factors: rising interest of international students to regional universities (demand for certain educational programs); special characteristics of the Siberian region (climate, peculiarities of university, urban, regional environment); little experience of regional universities in teaching international students required constant monitoring for adaptation difficulties; need to optimize support to international studentsconsidering socio-cultural difficulties. The study aims to establish, analyze and classify the problems of socio-cultural adaptation; to define spheres particularly demanding support for international students in a Siberian region. The research methods were theoretical (analysis, synthesis, concretization, generalization); diagnostic (questionnaire); statistical ones. The questionnaire was carried onwith participation of 83 students from far-abroad countries studying the bilingual program (General Medicine Department, Siberian State Medical University) based on the international scale of socio-cultural adaptation. The calculations were madeusing IBM SPSS Statistics software. It resulted in revealing the factors contributing to psychological, socio-cultural, didactic barriers impeded learning process; identifying various types of difficulties affecting the process of socio-cultural adaptation were pointed out: basic, ethno-cultural (humor perception), regional (climate, searching familiar food), individual (participation in social events). The study establishes directions to support international students, ensure their successful integration into new cultural and educational community. The results should be useful for specialists of social and psychological services for timely assistance to international students of the Siberian regional universities; in preparing international students for learning and living in new socio-cultural conditions.
