Implementation of Food Safety Management in the Food Industry in Algeria: Benefits and Barriers Factors
Authors: Boulfoul Nouara , Brabez Fatima
Published: September 2022

The key objective of this research review is to elucidate the mechanisms for applying a food safety scheme based on the Hazard Analysis and Critical Control Points (HACCP) system and to identify the difficulties and benefits of this technique (HACCP) in Algeria. Characterization of food processing companies around the capital of Algeria was carried out on the basis of questionnaires and direct interviews with the manager in charge of these companies. Forty-six agri-food firms working in the Algiers region and operating in the field for more than 15 years (80.5%) with Joint Stock company (JSC) status (23.9%), Limited Liability Company (LLC) (63%) and multinational companies (26.1%). The establishment of a transparent and effective framework for food safety controls will enable compliance with customer requirements, improved product quality and a stronger commitment to food safety managers. This is favorably correlated with the age as well as the level of education of the managers of the different surveyed companies. The survey conducted in the Algerian region showed that the key barriers to the introduction of the food safety management system (FSMS) in general are inadequate knowledge and competence of the HACCP and a long time to be developed FSMS, a lack of expertise and technical support and a lack of specialized expertise, intelligence and technological assistance to help the small and medium-sized enterprises (SME). The findings of the survey also revealed that the key reason for the introduction of the FSMS is to strengthen product protection, recognize the strengths and shortcomings of the business, enhance relationships with suppliers and enhance government and consumer confidence.
Empirical Analysis of Productivity among Broiler Farmers
Authors: Onuwa Godfrey
Published: September 2022

Broiler production supplements income of smallholder farm households. Profitability and productivity and analysis are important considerations in measuring efficiency or performance of a farm business; hence, improved output and income are not only a function of increase in the scale of production, but also how efficiently the resources are being utilized. This study therefore estimates the profitability and level of productivity among broiler farmers in Jos North, Plateau State, Nigeria. Multistage sampling technique was employed to select respondents for this study. Primary data collected were analysed using descriptive statistics, farm budgeting model and Total Factor Productivity (TFP) analysis. The study revealed that the net farm income of broiler production was ₦96,900/flock size; suggesting a relatively profitable venture with prospects for improved economic potentials. The estimated percentage profit margin was 45.6%; indicative of the percentage net margin accruable to the farmer from the estimated gross margin and benefit-cost ratio was 0.84. Furthermore, most (54.3%) of broiler farmers were sub-optimally productive as their TFP indices were below the optimal scale; attributable to sub-efficient input mix and cost of production inputs. In addition, constraints of broiler production in the study area included the following; high cost of feeds (92.9); high cost of chicks (85.7%); financial constraints (80%); high cost of poultry equipment (55.7%); high cost of medication (35.7); disease outbreak (28.6%) and inefficient market system (21.4%). Improving access to and subsidy of poultry feeds, chicks, production inputs and credit, extension, medical services and cooperative formation for market linkages are strongly recommended.

Authors: Devraj Radhika , Wilhelm Miranda , Deshpande Maithili
Published: September 2022

Background: Cost and lack of knowledge are key barriers to improving shingles vaccination rates in community pharmacies. A health literacy (HL) tailored infograph intervention addressing these barriers can enhance consumer interest in shingles vaccinations. 
Objectives: The objectives were to: 1) design a health literacy tailored shingles infograph addressing cost and knowledge about vaccination barriers, 2) determine consumer perceptions of infograph usefulness, and 3) determine factors associated with shingles vaccination plans.
Methods: An infograph addressing the study objectives, and a 22-item self-administered questionnaire assessing shingles vaccine awareness, HL, infograph usefulness, and vaccination plans were designed. The infograph was pilot tested with pharmacists and two community-based focus groups. Inclusion criteria consisted of age-eligible consumers at one chain and three independent community pharmacies.  Consenting participants first reviewed the infograph and then completed the survey.  Descriptive statistics and multivariable logistic regression analyses were performed. 
Results: Of the 422 eligible consumers approached, 112 participated in the study, with 55.4% from the chain pharmacies.  Participants were female (56%), white (94%), between 50-70 years old (77%), had adequate HL (96%) and aware of the shingles vaccine (87%).  While only 8% of the respondents considered vaccinating on the survey date, 46% considered it in the future, and 29% planned to in the next six months. The infograph was useful (90%) in recognizing vaccination need, was readable (95.5%), and understandable (96%).  Consumers who found the infograph useful were significantly more likely to have vaccination plans (OR= 4.06, CI: 1.37 – 11.9, p=0.016). 
Conclusion: A shingles vaccine infograph focused on key barriers to vaccination was well-received and useful in promoting consumers’ vaccination plans.
AA amyloidosis presenting with acute kidney injury, curable or not?
Authors: Uysal Berfin , Vuruşkan Berna Aytaç
Published: September 2022

Background. Amyloidosis is a group of disorders with extracellular accumulation of autologous fibrillary insoluble proteins in various tissues and organs such as the kidneys, liver, spleen, heart and gastrointestinal tract leading to impairment of normal organ function. Childhood amyloidosis is an exceedingly rare entity mainly caused by familial Mediterranean fever (FMF) and the other autoinflammatory diseases such as mevalonate kinase deficiency (MKD).
Case. A 16-year-old male was referred to pediatric nephrology for coincidentally discovered proteinuria. He had no significant findings on physical examination except for urochromic color. He had nephrotic range proteinuria with 109 mg/m2/h and serum creatinine was 1.35 mg/dl. Kidney biopsy was performed because of nephrotic range proteinuria with acute kidney injury. In hematoxylin-eosin-stained tissue sections, amyloid was suggested as extracellular amorphous material that is lightly eosinophilic in the glomeruli. Diagnosis was confirmed by Congo red positivity, with apple-green birefringence under polarized light. MEFV gene mutation was negative and a compound heterozygote mutation found in mevalonate kinase gene. A 6-monthtrial of colchicine, enalapril, and losartan combination was not successful; Canakinumab was started thereafter. Proteinuria and creatinine decreased to 7 mg/m2/h and 0.6 mg/dl respectively 4 years after treatment.
Conclusions. Amyloidosis should be considered especially in children presenting with proteinuria and with a history of recurrent fever. This report also emphasizes the efficacy of canakinumab to prevent or decelerate chronic renal failure in these patients although it does not reduce tissue deposition in long-term use.
Fucosidosis: clinical and molecular findings of Turkish patients
Authors: Şanlı Merve Emecen , Uysal Serap
Published: September 2022

Background. Fucosidosis is a rare, autosomal recessive lysosomal storage disease caused by alpha L- fucosidase enzyme deficiency in all tissues. Here, we identify a patient with a novel homozygous pathogenic variant and atypical clinical findings and summarized the clinical and molecular features of Turkish patients reported in the literature and present.
Case. The patient was born to consangineous parents at the 28th week of gestation. He had developmental delay that was attributed to prematurity. At he age of 2.5 years, brain magnetic resonans imaging revealed hyperintensities of symmetrical periventricular, subcortical, centrum semiovale and corona radiata regions on T2 and FLAIR weighted images. He developed seizures and showed developmental regression at he age of 3,5 years. Beside, coarse facial features and hepatomegaly were detected on phsyical examination. Lysosomal enzyme analysis revelaed alfa fucosidase deficiency and molecular genetic analysis identified a novel homozygous pathogenic p. Lys431 fs variant in FUCA1 gene.
Conclusions. In Turkish patients no distinguishable clinical and radiologic finding could be established. Molecular analysis was performed in few patients. Increasing of molecular and biochemical facilities might enable to make diagnosis and increase the prevalence of the disease in countries with high rate of consanguineous marriages. Moreover, it will provide genetic counseling, and enlighten the therapeutic effects of hematopoietic stem cell transplantation.

Background. Hereditary bone marrow failure syndromes are a category of biologically different syndromes that can cause cytopenia in at least one hematopoietic cell lineage.
Case. We present a 29-week-old male infant who had a low Apgar Score, advanced delivery room resuscitation, widespread petechial rash, and ecchymoses at birth, without any dysmorphic features. Initial laboratory tests revealed bicytopenia (platelet count 7x10 3 /uL, hemoglobin of 3.9 g/dL, neutrophil 2.0x103 /uL) with findings of disseminated intravasculer coagulation (DIC). Imaging studies demonstrated accompanying left-sided congenital pulmonary airway malformation. On the second postnatal week pancytopenia occurred and the bone marrow findings were consistent with congenital amegakaryocytic thrombocytopenia. Further evaluations for differential diagnosis of pancitopenia were performed and the results of congenital viral infections, metabolic and immunologic tests were negative. While supportive treatments were in progress, haploidentical bone marrow transplantation (BMT) was performed from the father at 84th day due to unavailability of HLA-matched relative or nonrelative donor. Whole exome sequencing revealed a novel heterozygous frameshift variation (c.1242dupT [p. Thr538fs]) in exon 8 of the MECOM gene and validated by Sanger sequencing. No variation was detected in the parents genetic analysis.
Conclusions. In this report, we present a patient with congenital bone marrow failure successfully treated with haploidentic BMT and describe a novel, de novo pathogenic variant in MECOM gene.
Rare cause of ketolysis: Monocarboxylate transporter 1 deficiency
Authors: Bozacı Ayşe Ergül , Ünal Aysel Tekmenuray
Published: September 2022

Background. Monocarboxylate transporter 1 (MCT1) deficiency (MIM #616095) is a relatively new identified cause of recurrent ketoacidosis triggered by fasting or infections. MCT1 was first described in 2014 by van Hasselt et al. to result from both homozygous and heterozygous mutations in the SLC16A1 gene. Patients with homozygous mutations are known to have a more severe phenotype with developmental delay and epilepsy. Thirteen patients with MCT1 deficiency with ketoacidosis have been reported in the literature to date.
Case. We describe a developmentally normal male patient with heterozygous missense variation in the SLC16A1 gene. Our patient who presented with cyclic vomiting and ketoacidosis episodes was found to have a heterozygous c.303T > G (p.Ile101Met) missense mutation.
Conclusions. It is crucial to take early preventive measures and to minimize the harmful effects of ketoacidotic episodes. MCT1 deficiency should be considered in the differential diagnosis of ketoacidosis in patients with normal SCOT and ACAT1 activities.

Junctional Bradikardia pada Pasien Hiperkalemia
Authors: Suwari Cokorda Istri Padmi , Puradipa Bayu , Wulandari Ni Luh Eka Sriayu
Published: September 2022

Hyperkalemia is a life-threatening electrolyte abnormality resulting in cardiac arrhythmia. Hyperkalemia may also cause bradycardia with junctional rhythm. However, the prevalence of hyperkalemia accompanying symptomatic bradycardia has only been explored in a few case reports. Thus we present a case of hyperkalemia with uncommon ECG findings. It has been reported that a 76 years old woman with type 2 diabetes mellitus, hyperkalemia and suspected coronary artery disease complaining about palpitation. Electrocardiography (ECG) showed junctional bradycardia with tall T wave and laboratory examination showed mild hyperkalemia (5.8 mmol/L). After one day of observation, severe hypotension was detected. Unexpectedly the cardiac rhythm was returned into the sinus after correction of hyperkalemia using calcium gluconate, insulin, dextrose, and salbutamol. As serum potassium level rises, sinoatrial and atrioventricular conduction was blocked, causing escape rhythm (junctional escape rhythm). In hyperkalemia, cardiotoxicity can be caused by an increase in resting membrane potential, decreased depolarization and duration of depolarization. When detected on ECG, hyperkalemia should be treated urgently and important to identify underlying causes or precipitating factors of hyperkalemia. Sinus node dysfunction is not excluded in this case.  Hyperkalemia can present a bradycardia junctional rhythm. Although the increasing serum potassium levels were low, hyperkalemia may have affected the conduction system leading to the ECG changes.Keywords:  hyperkalemia, junctional bradycardia, symptomatic bradycardia
Trabajo y trabajadores sociales: La construcción de la experiencia de trabajo de profesionales del trabajo social en Colombia
Authors: Bermúdez Peña Claudia
Published: September 2022

Esta investigación aborda la construcción de la experiencia que sobre el trabajo realiza un colectivo de profesionales del trabajo social desde la intersubjetividad, quienes se encuentran empleados en tres tipos de organizaciones: una organización gubernamental (OG), una organización no gubernamental (ONG) y una fundación de responsabilidad social empresarial (RSE) en Colombia, teniendo como perspectiva de análisis la intersubjetividad. El presente estudio no es sobre condiciones laborales de trabajadores sociales, pues si bien esta dimensión comprende asuntos del orden objetivo (tales como tipos de contrato, salarios, horarios, entre otros asuntos), interesa lo que de ella destacan los profesionales en sus relatos (tanto individuales como colectivos). Asimismo, no se centra en el contenido del trabajo o en el tipo de intervención social que hacen, sino que la atención está puesta en la construcción de la experiencia de trabajo, es decir, en las reflexiones que profesionales del trabajo social realizan sobre la vivencia de trabajar, a partir de su mundo cotidiano. Tampoco es un estudio en el marco de la sociología de las profesiones. Se trata más bien de una contribución a los estudios interdisciplinarios sobre el trabajo visto desde la experiencia de profesionales del trabajo social institucionalizados, que llevan a cabo su ejercicio profesional en algunos escenarios que históricamente han sido representativos en relación a esta disciplina. El documento está organizado en diez capítulos. Los cinco primeros realizan una ubicación contextual y teórica, así como también describen la estrategia metodológica asumida (cualitativa, con un alcance exploratorio-descriptivo), las categorías de análisis del estudio y el estado del arte. También dos de los capítulos presentan una contextualización histórica. Los últimos capítulos dan cuenta de los hallazgos y las conclusiones, dejando planteadas nuevas líneas de investigación que merecen continuar explorándose
Three-Dimensional Magnetohydrodynamic Analysis of a Magnetic Sail Using a Deployable Modular Structure
Authors: Arita Shoko , Yamagiwa Yoshiki
Published: September 2022

To obtain significant drag from a magnetic sail, it is necessary to generate a large magnetic moment. However, even with superconducting coils, a coil radius of several kilometers is required to obtain a significant drag force due to the magnetic moment generated by the coil alone. Therefore, several methods have been proposed to expand the magnetosphere generated by the coil, such as mini-magnetospheric plasma propulsion devices. This paper proposes a method to expand the magnetosphere and increase the drag by arranging multiple coils printed on a thin membrane in a deployable modular structure. To investigate the increased drag achieved by using this arrangement, a three-dimensional magnetohydrodynamic analysis is performed, and the drag coefficient and the shape of the magnetosphere are compared for several different coil arrangements and distances between coils. It is found that the drag force depends on the coil arrangement and that the effect is related to changes in the structure of the magnetosphere.
Flight Simulation and Drag Prediction for a Pitching-Accelerating Hypersonic Reentry Vehicle
Authors: Khalil Mostafa , Abdel-Gawad Mohamed S. , Ahmed Mahmoud Y. M.
Published: September 2022

A nonwinged reentry vehicle, such as the upper stage of a ballistic missile, endures harsh aerodynamic loads during the phase of reentry. This phase is characterized by sophisticated flight phenomena including hypersonic speed, continuous variation of surrounding atmospheric conditions, and pitching transient vehicle motion. During the flight in this descent phase, drag is considered the dominant aerodynamic force where accurate prediction is crucial as far as reliable trajectory prediction and mission planning are concerned. This study aims to investigate drag on a generic bi-cone nonwinged reentry vehicle resembling an upper stage of a ballistic missile during descent. This is done by using both trajectory prediction and numerical simulation of vehicle–air interaction. To obtain the vehicle dynamics and instantaneous flight conditions through descending phase, a three-degree-of-freedom pitch flight trajectory model is utilized starting from point of separation. It was concluded that the vehicle experiences small-amplitude pitching motion while descending from about 90 to 30 km and accelerating in a hypersonic regime (Mach 5.7–7). Drag is then calculated via time-dependent numerical simulations. The results show the flowfield pattern evolution in addition to the temporal variation of drag on the vehicle during the flight phase in concern.

The conventional reachable domain problem for satellites with a single impulse under the ideal two-body dynamical environment was extended to a more realistic scenario that takes [Formula: see text] perturbation into account. Such an extension enables the reachable domain to model the medium-term evolution of a debris cloud and to facilitate the orbit maneuver planning by exploiting the [Formula: see text] effect. First, the reachable domain under [Formula: see text] perturbation is defined as the collection of osculating orbits. To solve the boundary surface of the reachable domain, the three-dimensional reachable domain is reduced to a two-dimensional problem by discretization onto cross-sectional meridian planes of the central body. In this manner, the two-dimensional cross-sectional reachable domain can be expressed as a family of two-variable parameterized curves. Then, the reachable domain boundary is formulated by using envelope theory. A rigorous algorithm is proposed to solve the reachable domain boundary. The computational efficiency and accuracy of the algorithm are also analyzed. The results show that the computational time of a reachable domain is at the level of seconds on a personal desktop. The accuracy can be guaranteed as long as the [Formula: see text] perturbation assumption is valid. Finally, the dynamical evolution of the reachable domain from a toroid to a band, driven by the [Formula: see text] perturbation, is successfully modeled.
Fluid/Structure Interaction of Cantilevered Plate in Supersonic Separated Flow

Published: September 2022

The fluid-structure interaction of a cantilevered plate geometry in Mach 2 flow was studied experimentally to assess the effects of structural compliance on the surrounding flowfield. The test geometry, representative of a compliant control surface, consists of an overhanging plate that extends past the edge of a backward-facing step to create a separated region in the flow. This allowed for the study of recirculation effects and unsteady pressure forcing on the cantilevered plate without shock/boundary-layer interactions that would be present if the plate were inclined to the flow. Rigid and compliant test articles were studied to capture the fluid response with and without structural deformation. Schlieren photography and particle image velocimetry showed that under the unsteady conditions during startup of the wind tunnel the flexible plate exhibited a highly dynamic oscillatory response with frequencies similar to its natural vibration response. Under steady, started supersonic flow conditions, the flexible cantilever exhibited smaller oscillations around a mean deflection of two plate thicknesses. Oil flow visualization revealed nontrivial three-dimensionality of the test section flowfield. Modal decomposition of stereo digital image correlation measurements demonstrated that the distinct frequencies present in the flexible plate’s response consistently correspond to the same mode shapes.

Published: September 2022

This paper describes multidimensional modeling of ablation heat transfer with a focus on ablative insulation materials used in rocket motor nozzles. Phenomenology is discussed, and detailed three-dimensional math models are presented along with a finite element solution strategy. Implementation into a computer program named Hero is described, including a description of the parallel processing capability that enables computational support for large finite element models. A validation case is presented using measurement data from booster motors of the space shuttle program. The validation results are quantified in terms of the probabilistic propensity for misprediction of the char depth at varying levels. The validation results show a trend toward the overprediction of char depth by around 4%. The standard deviation of percent misprediction is shown to be between 6 and 16%, depending on boundary condition fidelity. This suggests that accuracy to three standard deviations can be expected to fall in the range of 18–48% for ablation modeling in rocket nozzles. This paper provides an important reference for multidimensional ablation heat transfer analysis and quantification of related modeling uncertainty.
CONTEMPLATOR VS FRUSTRATED WANDERER: DOUBLE FACED CHARACTER IN “NOTES” BY A. PLATONOV
Authors:   Institute of Philology of the Siberian Branch of Russian Academy of Sciences (Novosibirsk, Russia), Proskurina E.N.
Published: September 2022

Statement of the problem. “Notes” by A. Platonov are included in the corpus of his early lyrical and philosophical stories. These include the works of 1921 “The Beggar’s Thirst”, “In the Starry Desert”, “Poem of Thought”, “The Impossible”. However, until now “Notes” has not been analyzed as part of this range of works. The purpose of this article is to analyze the type of hero, poetics of the plot, to show the unity of the “Notes” with other lyric and philosophical stories written by Platonov; to reveal the dynamics of the hero’s image and the strategy of the plot of the story; to reveal his special place among the named works; to show the connection of Platonov’s hero-wanderer with Zarathustra F. Nietzsche, as well as the Nietzschean origins of some motives in Platonov’s stories. Conclusions. Unlike other lyric and philosophical stories, “Notes” have a two-part structure. The principle of counterpoint, organizing the two parts, is justified by the author’s logic: it moves from a speculative fascination with the sight of “endless spaces” and “distant villages” to disillusionment with real life. Thus, both parts exist in agreement with each other, forming a single textual whole with a contrasting basis embedded in it. With his “Notes” Platonov completes one of the areas of his own creativity, sums up his complex lyric, philosophical and utopian reflections. In further creative perspective, the utopian prospectuses turn more and more clearly into their genre opposite.
GENERATION OF THE 1880S IN A.P. CHEKHOV’S PROSE: MOTIF REPRESENTATION AND PLOT DYNAMICS
Authors:   Novosibirsk State University (Novosibirsk, Russia), Sinyakova L.N.
Published: September 2022

Statement of the problem. The article deals with motifs and anthropology problems of the 1880s generation based on A.P. Chekhov’s prose (“Excellent People”, “On the Road”, “Verochka”, “Lights”). The purpose of the article is to reveal the main Chekhov’s motifs to describe the generation, and then to investigate Chekhov’s plot dynamics from 1886 to 1888. Research results. The characters of “Excellent People” are determined by false activity, boredom, doubt, leaving home and changeable/unchangeable motifs. The inner event is outlook searches for a female character, forming Chekhov’s “opening” short story genre. The motif markers of the 1880s generation in “On the Road” are enthusiasm, aimlessness, recurrence, and empathy. The main hero is looking for his credo during all his life, so he may be called the “searching” hero. The hero of “Verochka” is a kind of a “weak man” type. The author’s interpretation of the type is represented by misunderstanding, loneliness, eligible bachelor runaway and old aged soul. Finally, the male character turns into an “ordinary man” literary type. The plot moving in “Lights” is provided by pessimism, skepticism, disillusion, guilt, real life and the common idea motifs. The last motifs are connected with the main hero rejecting philosophic reflection and his acceptance of life in its variety. The change in the combinations of motifs in Chekhov’s stories about the “eighties” during the critical period of the writer’s work allows us to trace the development of the author’s concept of the generation

Statement of the problem. Many studies using different methods have been devoted to the study of the professional group “teacher”. Professional values and individual typological features of personality are studied by V.A. Slastenin. Professional and value orientations of a social group of teachers were considered by E.A. Vereshchagina. The image of a teacher is described in the works of A.D. Vasilyev, S.P. Vasilieva. This article presents the results of a sociolinguistic experiment among teachers of Krasnoyarsk as a socio-professional group in the conditions of modernization of the Institute of General Education. The purpose of this article is a linguo axiological analysis of the results of the study of the terms in the field of “Education” by the method of subjective scaling among representatives of the professional group “teacher” in Krasnoyarsk. As a result of the study, the following conclusions were obtained: the technology of problembased learning was evaluated by the subjects with the largest number of “very good” ratings, the competence approach was noted among the subjects with the largest number of “bad” ratings, in the implementation of which a number of difficulties were outlined.
THE CONCEPT OF SIBERIAN FEDERAL UNIVERSITY IN THE ASPECT OF LINGUOIMAGEOLOGY
Authors:   Siberian  Federal University (Krasnoyarsk, Russia), Zhmakina I.S.
Published: September 2022

The article discusses the concept of “Siberian Federal University” in the aspect of the theory of linguoimageology, the aim of which is to study and develop technologies for creating an image of someone, something through the use of language tools that effectively influence the creation of a positive image of an object. The purpose of the article is to create an image modeling of the Siberian Federal University based on the exclusive properties of this object. In the course of a linguo-cognitive analysis of empirical material (journalistic texts about SibFU), the components of the concept under study were identified; a frame-type model has been built, providing for the conceptual, pragmatic and evaluative characteristics of frame slots; the types of estimated values that prevail in the texts about the reserve are determined; the frequency of linguistic means – artistic tropes used in creating a positive image of the object under study – has been established. Analysis of the empirical material based on this model made it possible to identify gaps in the texts about the Siberian Federal University, which can be taken into account when creating new texts by the press service of the university and regional media. The developed methodology can be applied to the analysis of the image component of other iconic regional objects.
