According to the national statistics, the Information Technology (IT) industry provides massive rapidly growing strength of the workforce in Sri Lanka. When consider the job availability of the IT industry it mostly depends on the five skills of the applier. Programming language, full-stack development, front-end development, back-end development, and databases are playing a major role in IT skills. This paper presents a recent survey on those five major skills used by Sri Lankan employees in the IT industry and a recent index of their popularity and industry trends. The internet job database was selected as the data gathering source for this study. Then Statistical Package for the Social Science (SPSS) was used for analyzing the sample dataset. Job skills examine with job opportunities in entry-level, mid-level, and senior-level. Based on the analysis, research found that what are the expectations in each level of jobs in the current IT job market. The result of this research should be useful to job seekers, IT stakeholders, and also fresh undergraduates can be obtained a crystal-clear analysis about the new trends based on programming languages and other essential requirements of the current IT sector.
The impact of a Biblical Fatherhood Programme for faith communities in the Christiana district: A reflective and community engagement strategy
Authors: Freeks Fazel E.
Published: November 2022

The farming communities in the Christiana district with a population of close to 21 000 residents struggled with issues including poverty, unemployment, financial problems, alcoholism, occultism and Satanism and family issues such as father absence, fatherlessness and single parenting. An intervention that included training and equipping of fathers, who were farm workers from the local faith community, was necessary and crucial. Farm workers (faith communities) responded to the need for a biblical fatherhood programme. Human fatherhood should be recognised and given serious consideration because it gave an anticipation of who God the Father is. If human fatherhood did not exist, then all truth and knowledge about God the Father would be void and insignificant. Fatherhood today is an element of broken families and perhaps the most threatened element in the world. The aim of this article was to lessen the social issue of father absence through the implementation of the Biblical Fatherhood Programme. The programme has a biblical nature to solve social ills within communities. The programme was developed from a practical-theological study on fatherhood, with the primary reason to train and equip participants with fatherhood knowledge. This article presents a reflective and community engagement strategy, based on the author’s reflection of items that arose when a biblical fatherhood programme was presented to farm workers in the Christiana district of South Africa. Reflection as a methodology enabled researchers and practitioners to theorise from their own practice, improving and developing their work. Reflection was a turning back onto ‘a self’ where the researcher was the observer of the scenario. Reflection was also a significant and mental activity for researchers to use in their work with participants. The results and this article presented the reflective, rather than empirical findings of the programme implementation. The training intervention was presented in a narrative form and based on research about the essence of fatherhood. This was conceptualised from biblical truth and perspective. Participants showed immense interest in the programme and the Bible. Their theological views concerning the Bible for answers were crucial to their problems and situations. Participants’ spiritual life was pivotal to enjoy healthy relationships with God.Contribution: The programme contributed monumentally to the lives of participants. It was impossible for participants to live their lives without the Bible. The Bible is not just an authoritative source of teaching, but it speaks of human fatherhood and serves as a guideline to enunciate the care of God the Father.

Are you really sitting comfortably? A field study of a forward sloping chair and sedentary low back pain sufferers
Authors: Bridger R. S. , Jaros G. G.
Published: November 2022

A number of authors have suggested that office chairs designed to encourage users to sit with an "open" trunk-thigh angle (approximately 110-120 degrees) will be more comfortable than conventional chairs and will have beneficial consequences for sedentary low back pain sufferers.This assertion was investigated in a 4 month trial in which 35 sedentary workers were given a forward sloping chair to use. Ratings of perceived back pain and postural comfort when using the chair were compared with ratings obtained when conventional chairs were used. Additionally, users' comments on both chair types were obtained.For the sample as a whole, significantly less lower back pain was reported on those occasions when the forward sloping chair was used. However, a number of participants reported no change or more back pain when using the forward sloping chair. Users’ comments on the chair highlighted a number of practical advantages and disadvantages which relate to its suitability for use in office settings.Although the majority of users preferred the forward sloping chair to their usual chairs, the available data do not permit the differential response to the chair to be explained on either personal, occupational, anthropometric or ergonomic grounds. A more clinically orientated investigation would seem to be required.
The efficacy of the simplified air cushion (SAC) compared to the polyurethane foam cushion with regard to ischial tuberosity interface pressure relief
Authors: Visser C. , Eksteen C. A.
Published: November 2022

This study was initiated in an attempt to compare the Simplified air cushion (SAC) with the Polyurethane Foam (PU Foam) wheelchair cushion with regard to effective pressure relief the study focused especially on the wheelchair bound spinal cord injured (SCI) patient.Thirty ulcer-free spinal cord injured (SCI) patients participated in this study. Patients were tested on a novice wheelchair cushion, namely the (SAC) as well as on the high-density PU Foam cushion, currently used in government subsidised hospitals. Ischial tuberosity interface pressures were measured under both ischial tuberosities by means of the Oxford Pressure Monitor MK 11 (OPM MK11).Maximum average pressures on the SAC were 73.60 mmHg and 82.97 mmHg on the PU Foam cushion. The results suggest that the SAC provides adequate pressure relief if compared to the PU Foam cushion. Due to the fact that the SAC is designed on the same principles as other air cushions, it provides a maximum support area which distributes the weight of the patient evenly, thereby lowering peak pressures. The SAC also has the ability to allow air circulation at the body interface, which aids in temperature control.
Diagnostic distribution and pitfalls of glandular abnormalities in cervical cytology: a 25-year single-center study
Authors: Sung Jung-A , Nikas Ilias P. , Kim Haeryoung , Ryu Han Suk , Lee Cheol
Published: November 2022

Background: Detection of glandular abnormalities in Papanicolaou (Pap) tests is challenging. This study aimed to review our institute’s experience interpreting such abnormalities, assess cytohistologic concordance, and identify cytomorphologic features associated with malignancy in follow-up histology. Methods: Patients with cytologically-detected glandular lesions identified in our pathology records from 1995 to 2020 were included in this study. Results: Of the 683,197 Pap tests performed, 985 (0.144%) exhibited glandular abnormalities, 657 of which had tissue follow-up available. One hundred eighty-eight cases were cytologically interpreted as adenocarcinoma and histologically diagnosed as malignant tumors of various origins. There were 213 cases reported as atypical glandular cells (AGC) and nine cases as adenocarcinoma in cytology, yet they were found to be benign in follow-up histology. In addition, 48 cases diagnosed with AGC and six with adenocarcinoma cytology were found to have cervical squamous lesions in follow-up histology, including four squamous cell carcinomas. Among the cytomorphological features examined, nuclear membrane irregularity, three-dimensional clusters, single-cell pattern, and presence of mitoses were associated with malignant histology in follow-up. Conclusions: This study showed our institute’s experience detecting glandular abnormalities in cervical cytology over a 25-year period, revealing the difficulty of this task. Nonetheless, the present study indicates that several cytological findings such as membrane irregularity, three-dimensional clusters, single-cell pattern, and evidence of proliferation could help distinguishing malignancy from a benign lesion.
Novel construction of quasi‐cyclic low‐density parity‐check codes with variable code rates for cloud data storage systems
Authors: Bhuvaneshwari Vairaperumal , Tharini Chandrapragasam
Published: November 2022

This paper proposed a novel method for constructing quasi‐cyclic low‐density parity‐check (QC‐LDPC) codes of medium to high code rates that can be applied in cloud data storage systems, requiring better error correction capabilities. The novelty of this method lies in the construction of sparse base matrices, using a girth greater than 4 that can then be expanded with a lift factor to produce high code rate QC‐LDPC codes. Investigations revealed that the proposed large‐sized QC‐LDPC codes with high code rates displayed low encoding complexities and provided a low bit error rate (BER) of 10−10at 3.5 dBEb/N0than conventional LDPC codes, which showed a BER of 10−7at 3 dBEb/N0. Subsequently, implementation of the proposed QC‐LDPC code in a software‐defined radio, using the NI USRP 2920 hardware platform, was conducted. As a result, a BER of 10−6at 4.2 dBEb/N0was achieved. Then, the performance of the proposed codes based on their encoding–decoding speeds and storage overhead was investigated when applied to a cloud data storage (GCP). Our results revealed that the proposed codes required much less time for encoding and decoding (of data files having a 10 MB size) and produced less storage overhead than the conventional LDPC and Reed–Solomon codes.

Published: November 2022

L’application des bonnes pratiques de production qui améliorent la productivité des systèmes agroforestiers à anacardier est limitée par le faible accès des producteurs à des microcrédits. L’objectif de cette recherche était d’évaluer l’accès et d’identifier les contraintes pour l’accès des producteurs d’anacarde à une ligne de crédit pour les acteurs de la filière anacarde dans les régions cascades, hauts bassins et sud-ouest afin de formuler des recommandations pour améliorer l’accès des producteurs au microcrédit. Les données ont été collectées à travers une enquête et l’état des déboursés de la ligne de crédit. L’accès des producteurs au microcrédit est réduit du fait de la compétition avec les autres acteurs de la filière, de la garantie, du retard dans le décaissement des microcrédits accordés, du déficit d’information et de structuration des producteurs. La mise en place de ligne de crédit spécifique aux producteurs d’anacarde et spécifique aux différentes opérations de production pour les producteurs, l’implication de l’interprofession de l’anacarde dans l’information pour augmenter la confiance des producteurs à adhérer à l’approche crédit, la mise en place des assurances agricoles ou de fonds de garantie et la structuration des producteurs sont des recommandations qui amélioreraient l’accès des producteurs au microcrédit.

The application of best production practices which improve the productivity of agroforestry systems with cashew tree is limited by the low access of farmers to microcredits. The objective of this research was to evaluate the access and to identify the constraints of cashew farmers access to a credit line for the actors of the cashew sector in cascades, hauts bassins and south-west regions in the aims to formulate recommendations for improving farmers access to microcredit. The data was collected through a survey and the disburshment state of the credit line. Farmers access to the credit line was reduced due to the competition with the others actors of the sector, to the guarantee, to the delay in disburshment of accepted credits, to the lack of information and farmers structuration. Putting in place credit line specific to the cashew farmers and specific to the different production operations for the farmers, involving the cashew interprofession in farmers information for increasing their trust to accept the credit approach, putting in place agricultural insurances or guarantee funds and farmers structuration are recommendations which could improve farmers access to microcredit.

Spodoptera frugiperda, est un ravageur exotique du maïs qui menace la sécurité alimentaire en Afrique subsaharienne en général et du Togo en particulier. Dans le but de contribuer à une gestion durable du ravageur, la présente étude vise à évaluer l’effet des associations maïs– soja et maïs-manioc sur la dynamique de la population et les dégâts du ravageur. Les traitements (culture pure de maïs, de soja, de manioc, association maïs-soja, et maïs-manioc) ont été installés suivant un dispositif en blocs aléatoires complets avec quatre répétitions. Les boutures de manioc ont été mises en terre un mois avant le maïs. Le maïs et le soja ont été semés simultanément. Les associations maïs-manioc et maïs-soja ont réduit respectivement l’infestation (56 et 40%), le nombre d’amas d’oeufs (50 et 25%) et de larves (57 et 43%), le taux d’attaque (45 et 34%) et les dégâts (40 et 27%) comparé à la monoculture du maïs. L’association maïs-manioc est plus efficace dans le contrôle du ravageur. En termes d’utilisation du sol, les associations maïs-soja et maïs-manioc (LER> 1) sont plus efficientes que la monoculture mais n’entrainent pas l’amélioration des rendements du maïs. Ces associations peuvent être envisageables pour une gestion durable de S. frugiperda.

Spodoptera frugiperda is an exotic maize pest that threatens food security in sub-Saharan Africa in general and Togo in particular. In the present study, the effect of intercropping maize with soybean and cassava on the infestation of the pest were studied. Field experiments were conducted using a device in complete random blocks with four repetitions. Cassava were planted one month before the maize and soybeans were planted simultaneously maize. Maize-cassava and maize-soybean intercropping respectively reduced infestation (56 and 40%), the number of egg (50 and 25%), larvae (57 and 43%) and damage (40 and 27%) of S. frugiperda compared with the monocrop. In terms of land use, maize-soya and maize-cassava associations (LER> 1) are more efficient than monoculture but do not lead to improved maize yields. The maize-cassava association is more effective in controlling the pest. These associations may be possible for the sustainable management of S. frugiperda.
A process capability index for zero-inflated processes
Authors: Pal Surajit , Gauri Susanta Kumar
Published: November 2022

The proportion of zero defect (ZD) outputs is as an integral characteristic of a zero-inflated (ZI) process or high quality process. Different ZI processes can almost equally satisfy the same USL of number of defects but they can produce substantially different proportions of ZD products. The application of conventional method for process capability evaluation fails to discriminate these processes because in the conventional method, the process capability is evaluated taking into consideration the USL of number of defects only. In this paper, a new measure of process capability for ZI processes is proposed that can truly discriminate different ZI processes taking into account the USL of number of defects as well as the proportion of ZD units produced in these processes. In the proposed approach, at first a measure of process capability index (PCI) with respect to the USL is computed, and then the overall PCI is obtained by multiplying it with an appropriately defined multiplying factor. A real-life application is presented.

Published: November 2022

In the present investigation, the influence of joint design on the microstructure and the mechanical properties of SAF 2205 duplex stainless steel welds are reported. Plates with two different joint designs were welded using the gas tungsten arc welding process. To investigate the sole effect of joint design, the joints were designed in such a way that both joints have similar groove volumes. The weldments were investigated for microstructural characterization, ferrite content, and microhardness study; later, they were subjected to Charpy V-notch impact test, transverse tensile test, and fatigue testing in order to investigate the mechanical performance. Both the weld joints were able to achieve 100% joint efficiency in view of the transverse tensile test. Different weld joint configurations demonstrated the influence of the differential heat dissipation characteristics of the joints, evident from different morphological features revealed through optical microscopy of the weldment. The welding affected the ferrite(α)-austenite(γ) ratio of the weld metals and differed the welds in terms of ferrite content in the root and weld pass. The weld zone of the U-joint showed a 65.8% ferrite fraction and thus showed 18% more hardness as compared to the V-joint, while the V-joint had the highest yield stress of 617 MPa. The study revealed that the U-joint performed better in comparison to the V-joint in terms of microhardness, impact toughness, and fatigue behavior. The U-joint could resist around 15% more fatigue cycles than the V-joint under high cycle fatigue.

Published: November 2022

Segmenting objects such as herd of cattle in natural and cluttered images is among the herculean dense prediction tasks of computer vision application to agriculture. To achieve the segmentation goal, we based the segmentation on the model of single objects by locations (SOLO) which is capable of exploiting the contextual cues and segmenting individual cattle by their locations and sizes. For its simple approach to instance segmentation with the use of instance categories, SOLO outperforms Mask R-CNN which uses detect-then-segment approach to predict a mask for each instance of cattle. The model is trained using synchronized stochastic gradient descent (SGD) over GPU to achieve a mAP of 0.94 making it 0.02 higher than the result recorded by the Mask R-CNN model. By using the focal loss, the proposed approach achieved 32.23 ADE on cattle contour detection making its performance better than the Mask R-CNN’s performance.

Wood biomass felling for fuel negatively impacted on the structuring and functioning of ecosystem worldwide. Consequently, increasing soil erosion, reduction in soil moisture, content, fertility, and decline vegetation cover. The study area comprised four districts: Leme, Rimi, Jama’a and Tilden Fulani in Toro LGA, Bauchi State, purposively chosen because of their high fuel wood activity. Charcoal producers were sampled, using stratified sampling methods while traditional leadership and the department of Forestry officials were purposefully sampled for their involvement in fuelwood and forest management of the area. Fifty (50) fuel wood and charcoal producers were chosen per district. A total of two hundred (200) sampled respondents and four each of the traditional leaders and forestry officials in the four districts were investigated. Apparent collapse of traditional governance system correlated with fuelwood exploitation (especially for charcoal production) and remained a threat to sustainability of forest and forest products management. Poverty was the main driver to resource destruction, as only 34% were employed.67%, 71% and 59% indicated impact on environment, temperature, and erosion due to charcoal production.Charcoal producers obtained the trees and logs for charcoal production from the natural forest and 88% of them use life trees, cutting above 40cm above the ground level. This method of harvesting from the forest inhibits replenishment commensurate with the rate of extraction. The study showed that poverty, unemployment, ignorance and lack of education have great and direct negative impact on the environment as global warming, ozone layer depletion and climate change are evident.
Nutritional status and serum vitamin A, protein and albumin levels in children six to fifty-nine months in Ahmadu Bello University Teaching Hospital Zaria
Authors: Abdullahi Sakinatu M , Mado SM , Akuyam SA
Published: November 2022

Background: Protein energy malnutrition (PEM) is a major public health problem in the tropical and subtropical regions of the world and often arises during protein and/or energy deficits due to nutritional inadequacy, poor socio-economic and environmental conditions and infections. Vitamin A deficiency (VAD) is an important health concern in severe malnutrition and has been found to be associated with significant morbidity and mortality. Children with PEM have greater deficiency of total protein and albumin and in severe cases the total protein may be reduced to about 50 per-cent. The objective of this study was to determine the serum vitamin A, total protein and albumin in malnourished children aged 6-59 months at Institute of Child Health Zaria.
Methods: This study was a case control health- based descriptive study to determine the relationship between serum vitamin A, protein and albumin levels among children with Protein Energy Malnutrition and their controls at Institute of Child Health, Ahmadu Bello University Teaching Hospital (ABUTH) Zaria. Using systematic sampling method, a total of 132 children (cases and controls) between 6 and 59 months of age were selected for assessment of their serum vitamin A, protein and albumin. Serum vitamin A level was analyzed by high performance liquid chromatography while the total serum protein and albumin levels were analyzed on the Boerhringer Mannheim Automated Hitachi system 704 using the Biuret and colour change methods respectively.
Results: The highest mean serum vitamin A (60.28±11.03μg/dl) and mean protein (61.24±10.12g/dl) among malnourished group were seen in marasmic –kwashiokor. For the controls, the mean serum protein is 62.96±5.99g/dl while the mean serum vitamin A is 59.44±13.90μg/dl. The overall mean serum protein for study group and controls were 50.2 4 ± 12.33μg/dl and 62.96±5.99g/dl respectively and the difference between them was statistically significant (p<0.01) The highest mean retinol (60.28±11.03) and albumin (38.43±30.14g/dl) were recorded among the marasmic-kwashiorkor malnutrition, while for the controls, the mean retinol was 50.44±13.90μg/dl and the mean serum albumin was 37.62±40.98g/dl. The overall mean serum albumin for both study group and controls were37.17±12.22g/dl and 37.62±40.98g/dl respectively and the difference between them was statistically significant (p<0.04).
Conclusion: The serumprotein and albumin showed positive correlation with serum vitamin A levels. The highest mean serum vitamin A, protein and albumin was seen in marasmic-kwashiorkor among under-nourished children

Published: November 2022

Introduction: Following the adoption of home based, table salt treatment for Umbilical granuloma in our practice, we observed that there was a paucity of report on the use of table salt for the treatment of Umbilical granuloma in African children. We report the outcome of treatment of eight children treated with Table salt in our facility.
Methods: We carried out a retrospective review of the medical records of infants who were diagnosed with umbilical granuloma and were managed using table salt in our hospital in 2016 and 2020. Additional data about diagnosis, treatment and outcome were extracted from records of electronic communications via emails and WhatsApp® between the Paediatrician and caregivers of these infants. Written informed consent of caregivers of the infants were obtained and the study received approval of the Research and Ethics Committee of our Hospital.
Results: Nine infants were diagnosed with Umbilical granuloma during the study period but informed consent was obtained for eight of them. All eight children (100%) treated with table salt had resolution of umbilical granuloma confirmed at the end of the treatment period without any adverse event.
Conclusion: Home based, Table salt treatment was found to be safe and effective treatment for umbilical granulomas among the children treated in our facility.

Published: November 2022

Assessment of the state of health and working condition of equipment in the production and service industries is a necessary condition for effective maintenance. Therefore, this work models the failure times and other operational characteristics of television transmitter system with sudden but non-constant failure rate to enhance smooth operation of the system. The failure times was shown to follow lognormal distribution with mean; 𝑥̅=7.6 and variance; 𝑠2=1.4. The Probability functions, hazard, reliability functions/indices, availability and maintainability factors were obtained to described the failure behaviour and ascertain the performance efficiency of the system. Also, a preventive replacement (PR) model for the system yielded an optimal replacement time of 189.112 hours at a minimum total cost of 178.134 naira per unit time. A combination of both estimates of the reliability indices and the PR model is recommended to provide complementary information for efficient maintenance operation of the TV transmitter and similar systems.
Dapagliflozin relieves renal injury in a diabetic nephropathy model by inducing autophagy through regulation of miR-30e-5p/AKT/mTOR pathway
Authors: Zhang Jun , Ding Ting , Zhang Ximei , Tang Dongxing , Wang Jianping
Published: November 2022

Purpose: To investigate the mechanism of action of dapagliflozin on diabetic nephropathy.

Methods: A rat model of diabetic nephropathy was established by injection of fructose-streptozotocin. Blood glucose and urinary protein levels were measured, while histopathological changes in kidney tissues were determined by hematoxylin & eosin staining (H & E). Serum levels of creatinine (Cr), blood urea nitrogen (BUN), malondialdehyde (MDA), superoxide dismutase (SOD), reduced glutathione (GSH), and lactate dehydrogenase (LDH) were evaluated by enzyme-linked immunosorbent assay (ELISA). Cell apoptosis and autophagy were investigated by evaluating apoptotic and autophagic protein expression by western blot.

Results: Administration of fructose-streptozotocin increased the blood glucose level of the rats (p < 0.001) and induced pathological changes in the kidney tissues, including glomerulosclerosis, renal tubule dilation, and inflammatory cell infiltration of rats. However, long-term treatment with dapagliflozin attenuated the fructose-streptozotocin-induced increases in Cr, BUN, and urinary protein and reversed the fructose-streptozotocin-induced decrease in Bcl-2 expression and increases in Bax and cleaved PARP expression in diabetic rats. Dapagliflozin also reversed the increases in MDA and LDH and decreases in SOD and GSH in diabetic rats. The fructose-streptozotocin-induced increase in p62 expression and decreases in LC3 and Beclin 1 expression were reversed by dapagliflozin. It upregulated miR-30e-5p expression and downregulated phosphorylated AKT and mTOR expression in diabetic rats. MicroRNA-30e-5p targeted AKT and inhibition of miR-30e-5p attenuated the dapagliflozin-induced decrease in p-AKT and p-mTOR expression in diabetic rats.

Conclusion: In fructose-streptozotocin-induced diabetic rats, dapagliflozin ameliorates kidney injury, suppresses cell apoptosis and oxidative stress, and promotes cell autophagy through upregulation of miR-30e-5p and inactivation of the AKT/mTOR pathway. Therefore, dapagliflozin is a potent therapeutic agent for the management of diabetic neuropathy.

Published: November 2022

Purpose: To probe into the effects of gamma globulin on the pulmonary functions, and C3 and C4 serum levels of septic children in pediatric intensive care unit (PICU).

Methods: Sixty-seven children with sepsis were retrospectively analyzed and assigned into study group (SG, n = 36) and control group (CG, n = 31) based on treatment modalities. The children in CG received conventional sepsis treatment, while children in SG were treated with gamma globulin. Differences in pulmonary function as well as C3 and C4 serum levels were compared in both groups before and after treatment. Children in SG were assigned into mild group (n = 21) and severe group (n = 15) in based on the severity of their conditions.

Results: After treatment, SG showed higher forced vital capacity (FVC) and peak expiratory flow (PEF) than CG (p < 0.05). SG also showed higher C3 and C4 serum levels than CG after treatment (p < 0.05).

Conclusion: Administration of gamma globulin to children in PICU significantly improves lung function and increases their serum C3 and C4 levels. C3 and C4 serum levels of septic children in PICU correlate with prognosis. Hence, C3 and C4 can be regarded as indicators for the diagnosis, evaluation and prognosis of septic children in PICU.

Ellos intervienen en situaciones en las que el sector público, el mercado y las organizaciones privadas no pueden hacerlo. Pero ¿qué diferencia al emprendimiento social de otros tipos de emprendimiento?, ¿se trata de una obra de ayuda social?, ¿será quizá otra manera de nombrar las acciones de responsabilidad social de las empresas o los proyectos de las ONG? Aquí te enterarás realmente de qué es, cuáles son sus características, cómo surge, cuáles son sus antecedentes en el Perú y en el mundo. Y, lo más importante, qué necesitas tú para sumarte a esta corriente.

Durante muchos años la enseñanza universitaria se ha visto influenciada por la racionalidad técnica, la cual conduce a la limitada capacidad de reflexionar sobre las acciones propias del quehacer profesional, menoscabando el diálogo reflexivo en la acción. De esta manera surge el interés de generar una propuesta de criterios para el Desarrollo y la Implementación de la estrategia de Aprendizaje Basado en Problemas fundamentado en el pensamiento de Donald A. Schön. Los criterios del pensamiento de Schön, facilitan implementar o reorientar la estrategia de ABP que favorecerá la apropiación de conocimientos relevantes en la práctica. Esta reestructuración promueve la autonomía y reflexión del estudiante, haciendo que su formación nazca desde perspectivas reales, considerando su batería de experiencias y conocimientos previos, su repertorio en torno al problema, y la generación de los espacios y oportunidades de reflexionar.

Propaganda, özünde bir iletişim sürecini içermektedir. Propaganda, kitlelerin düşünce ve davranışlarının dönüştürülmesi veya yönlendirilmesi amacıyla sistematik ve planlı bir şekilde gerçekleştirilen iletişim faaliyeti olarak ifade edilebilir. Propaganda, tarihin her döneminde olmakla birlikte Dünya Savaşlarından sonra daha fazla dikkat çeken bir olgu olmuştur. Dünya Savaşları’nda propagandanın yoğun bir şekilde kullanılması da kavramın olumsuz bir çağrışıma sahip olmasının sebebi olarak gösterilmektedir. Propagandanın nitelendirilmesine ilişkin olumsuz bakış açıları olmakla birlikte günümüz dünyasının da bir gerçeği olarak kabul edilmektedir. Propaganda çalışmaları kapsamında hedef kitleye mesajların iletilmesi için çeşitli iletişim araçları kullanılmaktadır. Sağladığı imkân ve olanaklar dolayısıyla propaganda çalışmalarında kullanılan iletişim araçlarının başında da sosyal medya gelmektedir. 24 Şubat 2022 tarihinde başlayan Ukrayna Rusya savaşında sosyal medya her iki tarafın kullandığı iletişim mecralarından biri olmuştur.

Bu çalışmada, Ukrayna, Rusya Savaşı’nda ilgili devletler tarafından yürütülen propaganda faaliyetleri sosyal medya kullanımı bağlamında incelenmiştir. Sosyal paylaşım ağı Twitter örneğinde gerçekleştirilen çalışma kapsamında Ukrayna Ankara Büyükelçiliği ile Rusya Ankara Büyükelçiliği’nin Twitter paylaşımları savaşın başladığı 24 Şubat ile 31 Mart 2022 tarihleri arasındaki süre kapsamında analiz edilmiştir. Çalışmada içerik analizi yöntemi uygulanmış ve elde edilen bulgular frekans tabloları oluşturularak analiz edilmiştir. Elde edilen bulgulara göre, Ukrayna Ankara Büyükelçiliği Twitter’ı daha yoğun olarak kullanmış; daha fazla paylaşım üreterek Rusya’nın Ukrayna’da sivillere ve sivil yerleşim yerlerine saldırılarını fotoğraf ve videolar ile birlikte paylaşarak propaganda çalışmalarının etkisinin artırmaya çalışmıştır. Rusya Ankara Büyükelçiliği ise paylaşımlarında Ukrayna’ya karşı başlatılan savaşın gerekçelerini açıklamaya ve buna ilişkin iddialarını fotoğraflar ve videolar ile paylaşarak güçlendirmeye çalışmıştır. Her iki ülke de paylaşımlarını büyük oranda Türkçe yapmışlardır. Ukrayna Ankara Büyükelçiliği Twitter paylaşımlarında daha fazla hashtag kullanarak mesajlarının geniş kitlelere ulaşmasını hedeflemiştir.

Bu yazı yakın dostum, entelektüel arkadaşım ve hakikat yolunda yoldaşım olan Prof. Dr. Sıddık Korkmaz hakkındadır. Kendisiyle 23 yıllık eskimeyen aksine yıllandıkça kıymetlenen dostluğumuza dair bir tanıklık metnidir. Ordu Üniversitesi tarafından gerçekleştirilen 27. İlahiyat ve İslami İlimler Fakülteleri Dekanlar Toplantısı kapsamındaki program sonrasında düzenlenen kültür ve turizm gezisi sırasında katılımcıları taşıyan aracın kaza yapması sonucu 26 Haziran 2022 günü hayatını kaybeden dostuma bitmeyecek olan vefa borcumun bir belgesidir. Buna benzer bir yazıyı, 26 Eylül 2020 tarihinde COVID’den kaybettiğimiz değerli bilim adamı hocam Prof. Dr. Hasan Onat için yazmıştım. Ondan 21 ay sonra yine çok sevdiğim ve değer verdiğim Sıddık Korkmaz hakkında yazmak benim için zor fakat zorunlu bir görev oldu. Bu makalede, kendisiyle tanıştığımız günlerden vefatına kadar olan süreçte Sıddık Korkmaz ile olan dostluğumuzu, kişisel paylaşımlarımız ve entelektüel yolculuğumuz bağlamında yazmaya çalıştım. Kaybettiğimiz her dostumuzla birlikte hayatımızın çok değerli anıları da tarihe karışmaktadır. Anılarımızın yok olup gitmemesi için arşivlenip kaydedilmesi, bir tanıklığa dönüştürülmesi ve belgelenmesi gerektiği düşüncesiyle bu yazı kaleme alınmıştır.

The urgency of finding ways and opportunities to intensify modern innovative practice determined the purpose of this publication, which is to highlight the results of research into the trends of innovative activity to ensure the growth and sustainable development of the economy of Ukraine, as well as to find factors that inhibit this process. This study is based on the thesis that in modern realities, to obtain a commercial or social effect, it is necessary to intensify innovative activity, as a set of processes aimed at creative search, formation, publication, and implementation of innovations in practice. Such activity involves making investments in objects of innovative activity. Methodological aspects of the study consider the concepts of identifying patterns of influence of the volume of expenditures on scientific, research, and design activities on the number of researchers involved in such activities, on the effectiveness of their research, and therefore on the state of innovative development of the state. The change in the positions of Ukraine in the rating evaluations regarding innovative development was investigated, a comparative analysis of the research and development costs of the leading countries of the world and Ukraine in 2020 was performed, the downward dynamics of changes in the number, organisations, and number of employees carrying out R&D, the costs of performing such works and the share were revealed of these costs in the gross domestic product of Ukraine during 2010-2020. The main factors inhibiting the process of intensification of innovative activity include a decrease in state funding of research and development, and therefore, a decrease in the number of organisations and researchers engaged in the creative activity of scientific research. Positive trends towards the formation of gender parity among the performers of scientific research work (47.6% are women), the growth of activity in the field of innovative activity and the increase in expenses of enterprises for innovative activity in 2020 have been revealed. It is proposed to start the development of an effective national innovation policy with the definition of the conceptual provisions of innovative development. The results of the study can be useful for a wide range of scientists who study issues of innovative development, specialists of management structures who analyse the state of innovative development and take care of issues of developing strategies for recovery and further development of the national economy.

The digital transformation of the leading countries towards the neo-economy effectively uses the potential of digital competences, which remain insufficiently explored in Ukraine, but it is already clear that they are the key to the inclusive economic growth of any country, namely the post-war revival and development of Ukraine at a highly competitive level. The purpose of this study was to find the specific features of the influence of the level of digital competences (according to DigComp 2.1) on the evaluation of the prospects for building a digital economy by Ukrainian citizens, and the perception of the processes of digital transformation of the economy by stakeholders. The information base of this study included online survey data, processed using the SPSS package. Found regularities were verified using standard statistical parameters of the relationship. At the first stage, the influence of the level of digital skills on the judgments, attitudes, and expectations of respondents on the prospects of digital transformation in Ukraine and the world was found. Depending on the attitude towards the development of ICT, the archetypes of the respondents were distinguished (optimist, pragmatist, agnostic, rationalist/cautious pessimist, and sceptic). The second stage investigated the impact of digital skills on various aspects of the life of Ukrainian citizens, namely on their daily life, on them as consumers and as workers. It was found that a higher level of digital skills contributes to improving the quality of respondents’ everyday life; there is an increase in the share of respondents who use Internet resources in everyday life. The key conclusions are as follows: 1) focused efforts on the development of digital skills will contribute to an increase in the share of optimistic and pragmatic assessments of digitalisation; 2) the detected digital gap between the possession of skills and the need for them (2-3 times) actualises the implementation of policies aimed at overcoming it; 3) the awareness of the impact of the level of digital skills on the development of citizens and satisfaction with the products of the digital economy is growing; 4) the digital transformation of the economy radically changes its structure, the landscape of the labour market, and has a major impact on every citizen. Foremost, those who have an elevated level of digital skills will be able to benefit from digitalisation
