THE SOCIO-PSYCHOLOGICAL FEATURES OF SUPERVISION GROUPS FOR NOVICE PSYCHOLOGISTS
Authors:   Zaporizhzhia National University, Spitsyna Larysa
Published: June 2021

This article highlights the socio-psychological aspects of supervision groups organised for psychologists who are just starting their practical activities, based on the analysis of the methodological framework of supervision in a group. Supervision is seen as a counselling form aimed at improving the quality of communication and cooperation in the professional sphere, as a form of professional support, primarily in the areas of helping professions - psychology, psychotherapy, social work, as well as in management. In the last twenty years, the interest in supervision has been associated with the rapid growth of consultative and therapeutic services, due to wider use of the biopsychosocial approach and the model of "community care". The European model of supervision, which focuses on the integrative approach to supervision, has become relevant to these new demands of increased practice. In this article, we proceed from the idea that the modern methodology for supervision, relevant to the complex and multi-level tasks of modern practice, is based on the vision and principles of the integrative approach. The integrative approach used in groups and organizational supervision involves a combination of the capabilities of the systemic, humanistic, cognitive, behavioral, psychodynamic directions with the principles of inter-subjective interaction, where the focus is on relationships between a supervisor and a supervisee. We also point out the expediency principle for choosing an approach used by a supervisor in a specific situation, depending on a subject, a supervision request and the supervisor’s focus at a certain stage of work. In this case, the main procedural model of practical work is the seven-dimensional model of supervision. A supervisor’s activity is implemented on the basis of the system of methodological principles given in the article. The central subject of our research was group dynamics under supervision, since it was proven that group supervision work was largely based on a supervisor’s understanding and conscious use of the resources of group dynamics. The effectiveness of this work largely depended on taking into account the regularities of stages, processes and phenomena of group dynamics.

Aim. Identification of structural elements, parameters and processes of electronic-digital transformation of the "green" economy model in the context of overcoming socio-economic and production-economic problems caused by the aggravation of the epidemiological situation in connection with the spread of COVID-19. Material and Methods. In the process of considering the problems of electronic digital transformations of the "green" economy in connection with COVID-19, general scientific methods of analysis, synthesis, genesis of new knowledge, methods of modeling and forecasting the most likely change in the socio-economic situation, methods of statistical and economic data analysis, methods of normative-legal analysis of strategic documents, methods of generalization, analogy and comparison of initial data. Results. The processes of transformation of the traditional economic system into a "green" economy during the spread of COVID-19 are based on the widespread use of digital technologies that provide the systematization of multidirectional information about the nature and level of morbidity of the population. This enables public authorities and the management of individual organizations to make informed managerial decisions on changing the mode of activity based on electronic technologies in accordance with the main conditions for the development of digitalization of the "green" economy. Conclusion. The formation of a sustainable system of "green" economy in a crisis situation of the COVID-19 pandemic is determined by the observance of a number of socio-economic, legal and technological conditions associated with the use of digital technologies. This provides expanded opportunities to fully inform the participants of public-private cooperation about the nature of the implementation of building a "green" economy. At the same time, the development of complex organizational, legal and economic measures to overcome the crisis situation during the spread of COVID-19 is taking place.

Aim. To study the feasibility of using feed additives containing powdered feed preparations with different lactulose content in the amount of 5 g/kg of extruded compound feed together with the main diet in terms of the effect on the quality indicators of raw materials and the natural resistance of the body of experimental rabbits. Materials and Methods. The effectiveness was evaluated after the control slaughter at the age of 150 days in the number of 5 heads from each group. The change in live weight was determined when the rabbits reached the age of 75, 105, 135 and 150 days by weighing on an electronic scale. The physiological state and resistance of rabbits were evaluated by hematological parameters. The obtained materials were processed by the methods of variation statistics. Results. The analysis of dynamics of changes of alive weight of animals showed that feed supplementation with lactulose had a positive impact on the growth of animals the live weight of rabbits in groups I and II were greater at 3.8 and 6.2% absolute increase in live weight during the period of experience increased by 5.3 and 7.9%, respectively, compared to control. At the same time, the effect of supplements on blood parameters should also be noted. In our studies, the rabbits of the experimental groups had an advantage over the rabbits of the control group in terms of the level of red blood cells by 0.94·1012 g/l (18.7%) and 1.12·1012 g/l; white blood cells - by 0.50·109 (7.2%) g/l and 0.59·109 g/l (8.5%), respectively. The level of hemoglobin in the blood of rabbits increased by the end of the experiment in the control group by 3.7%, in I – by 12.5%, in II – by 15.9%. Conclusion. Based on the presented results, it can be concluded that the data on quantitative changes in blood were due to the influence of feed additives, which contributed to an increase in the natural resistance of rabbits, and the best indicators were achieved by rabbits of the II experimental group.
Food fortification – a modern principle of the food industry
Authors:   Stavropol State Agrarian University, Kaishev V.G.
Published: June 2021

Aim. To analyze the scientific and technical literature and identify ways to create a new generation of mass-consumption food products enriched with vital nutrients. Discussion. The main malnutrition of the Russian population is the excess of caloric intake over an indicator of the level of energy consumption. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin, allows you to create active complexes that qualitatively change the physiological properties of the product, and can affect many product characteristics and processes such as physico-chemical, structural-mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Conclusion. When developing recipes and technologies for new-generation products, it is necessary that the enrichment of the product with important and necessary elements does not worsen the organoleptic characteristics. At the same time, it is necessary to ensure the safety of products without compromising consumer properties. The diet should contain all the necessary nutrients (nutrients) for a person in sufficient quantities and balanced with each other in the most favorable proportions.

Aim. Scientific substantiation of the ongoing processes of reducing biodiversity to the environment and their impact on the growth of threats to food security of the countries of the world. Material and Methods. General scientific methods of scientific research, methods of generalization and synthesis of scientific knowledge, methods of regulatory analysis of the current situation in the socio-economic sphere were used. All digital materials and data were obtained from open sources and used to substantiate the theoretical material in fact. To illustrate the materials, methods of graphical data presentation, statistical data evaluation and logical analysis were used. Results. The depletion of biodiversity dictates the need to search for new approaches to communication with nature and the use of its resources. The growing threat of destruction of the existing ecosystems that form the habitat of living organisms on the planet is forcing the countries of the world to revise their industrial technologies and applied mechanisms to ensure sustainable economic growth and food security. Population growth does not make it possible to reduce the rate of development for civilization, but requires intensification of efforts on the part of the leadership of world powers to reduce the rate of growth of global biological threats. Conclusion. The disturbance of the biological diversity of the planet indirectly affects the state of biocenoses and resistance to destruction and degradation. The anthropogenic influence of humanity and geometric population growth in numbers do not allow the biosphere to restore equilibrium after the intervention and consumption of its resources. The tasks of assessing the role of man in the formation of the problem of loss of biodiversity, the importance of preserving biodiversity for maintaining the life support of the growing earthly population, providing the entire population with the necessary level and availability of food for balanced and sustainable economic development were investigated and consistently solved. Of course, it is necessary to take a more serious approach to the conservation and protection of the planet's biodiversity.

Not all effects are indispensable: Psychological science requires verifiable lines of reasoning for whether an effect matters.

Published: June 2021

Psychological researchers currently lack guidance for how to make claims about and evaluate the practical relevance and significance of observed effect sizes, i.e. whether a finding will have impact when translated to a different context of application. Although psychologists have recently highlighted theoretical justifications for why small effect sizes might be practically relevant, such justifications fail to provide the information necessary for evaluation and falsification. Claims about whether an observed effect size is practically relevant need to consider both the mechanisms amplifying and counteracting practical relevance, as well as the assumptions underlying each mechanism at play. To provide guidance for making claims about whether an observed effect size is practically relevant in such a way that the claims can be systematically evaluated, we present examples of widely applicable mechanisms and the key assumptions needed for justifying whether an observed effect size can be expected to generalize to different contexts. Routine use of these mechanisms to justify claims about practical relevance has the potential to make researchers’ claims about generalizability substantially more transparent. This transparency can help move psychological science towards a more rigorous assessment of when psychological findings can be applied in the world.
Sufficient Reliability of the Behavioral and Computational Read-Outs of a Probabilistic Reversal Learning Task
Authors: Waltmann Maria , Schlagenhauf Florian , Deserno Lorenz
Published: June 2021

Task-based measures that capture neurocognitive processes can help bridge the gap between brain and behavior. To transfer tasks to clinical application, reliability is a crucial benchmark because it poses an upper bound to potential correlations with other variables (e.g., symptom or brain data). However, the reliability of many task-readouts is low. In this study, we scrutinized the re-test reliability of a probabilistic reversal learning task (PRLT) that is frequently used to characterize cognitive flexibility in psychiatric populations. We analyzed data from N=40 healthy subjects, who completed the PRLT twice. We focused on how individual metrics are derived, i.e., whether data was partially pooled across participants and whether priors were used to inform estimates. We compared the reliability of the resulting indices across sessions, as well as the internal consistency of a selection of indices. We find good to excellent reliability for behavioral indices as derived from mixed-effects models that include data from both sessions. The internal consistency was good to excellent. For indices derived from computational modelling, we find excellent reliability when using hierarchical estimation with empirical priors and including data from both sessions. Our results indicate that the PRLT is well equipped to measure individual differences of cognitive flexibility in reinforcement learning. However, this depends heavily on hierarchical modelling of the longitudinal data (whether sessions are modelled separately or jointly), on estimation methods, and the combination of parameters included in computational models. We discuss implications for the applicability of PRLT indices in psychiatric research and as diagnostic tools.
Evidence for, and challenges to, sensory recruitment models of visual working memory
Authors: Adam Kirsten C. S. , Rademaker Rosanne L. , Serences John
Published: June 2021

Visual working memory refers to the ability to temporarily hold information in mind in the service of behavior. Often, it is not sufficient to hold an abstract idea in mind to achieve our goals. Rather, we must maintain vivid sensory details. For example, when buying a spool of thread to repair a much-loved shirt, holding an abstract category in mind is not sufficient to buy the correct color (e.g. ‘blue’)—instead, you need a precise visual memory of the color (e.g., a particular gray-ish shade of blue). One proposal for how we maintain vivid, detailed information in mind is the sensory recruitment hypothesis. Sensory recruitment proposes that neural circuits already specialized for encoding sensory details during perception are likewise recruited to help maintain this information in working memory. In this review, we recount evidence that is consistent with a key role for early visual cortex in supporting visual working memory, we discuss key debates about the role of early sensory activity in supporting memory maintenance, and we outline a framework in which sensory codes are one part of a flexible, multi-level working memory representation.

Authors: Koirala Namu , Kafle Shyam P
Published: June 2021

Introduction: Self-directed learning is one of the concepts of learning which is mostly used in higher education, especially in the discipline of medicine and paramedics.

Objectives: The objectives of this study were to assess the self-directed learning readiness of the undergraduate nursing students and to find out its association with selected demographic variables.

Methodology: A descriptive, quantitative, cross-sectional study was undertaken among undergraduate nursing students from three nursing colleges of Eastern Nepal; from January 2019 to August 2020. The nursing colleges were randomly selected; one constituent nursing college and two colleges affiliated to Purbanchal University. Census sampling method was adopted and 565 students were enrolled. Ethical clearance was taken from the Institutional Review Committee of the institute. Data was collected using a self administered, valid and standard tool: Williamson's Self Rating Scale for Self-directed Learning (SRSSDL) via online google forms, then transferred to Microsoft EXCEL. Data analysis was done using SPSS 16.0 version. Mean, median, standard deviation, range, chi-square test, Mann Whitney U test and Kruskal Wallis H test were used for data analysis.

Result: Overall Self-directed Learning score was 244.83±30.15. The majority of the respondents (79.3%) had high scores of SRSSDL (221-300) and 20.7% of the respondents had moderate levels of SRSSDL (141-220). The demographic variables didn't exert any significant effect on the overall level of SRSSDL but varied only with the sub-dimensions of SRSSDL.

Conclusion: This study shows that overall self-directed learning among nursing students is moderate to high and the subdimensions have significant associations with demographics and academic level.

Published: June 2021

Introduction: Chronic Kidney Disease causes sudden changes in the daily lives of patients and creates a great impact on their quality of life. Failure of adherence in Hemodialysis can lead to increased morbidity, mortality, cost, and burden on health care system.

Objectives: This study was conducted to assess the quality of life and adherence to treatment of patients undergoing Hemodialysis.

Methodology: A descriptive correlational study was carried out at Nobel Medical College Teaching Hospital, Biratnagar, among 96 patients who were under HD using convenience sampling technique. The data was collected through face to face interview for the period of 5 months. Quality of life and adherence to treatment were assessed using Kidney Disease Quality of Life Questionnaire (KDQOL) and End Stage Renal Disease Adherence Questionnaire (ESRD – AQ) respectively. The data was analyzed using t test, Spearman correlation statistics.

Results In this study, the overall mean score of quality of life (QOL) of patients under HD was 48.9±13.7. More than half (54.1%) of the patients had moderate adherence to treatment while 31.2% had good adherence. Domains with the highest and lowest scores on quality of life and adherence to treatment were social domain and illness impact and adherence to HD treatment and diet restriction, respectively. There was statistically significant association between total score of quality of life and duration of HD (p≤0.05). Likewise, there was statistically significant association between adherence to treatment and marital status (p≤0.05), educational status (p≤0.05), ethnicity (p≤0.05), duration of illness (p≤0.05). Poor correlation (r= 0.273) was observed between quality of life and adherence to treatment.

Conclusion: On average, the kidney disease component dimension of quality of life of patients under HD is higher and the overall level of adherence to treatment was moderate. Thus proper periodic counseling on illness and its long term impact, regular follow up as well as information on adherance to dietary measures are important to improve the quality of life and treatment adherance of patients under hemodialysis.
A Comparative Study between Ketamine and Lidocaine ro Decrease Propofol Injection Pain During Induction of Anesthesia
Authors: Khadka Bikash , Sharma Nil Raj
Published: June 2021

Introduction: Pain during the injection of anesthetic agents may be distressing and can reduce the acceptability of an otherwise useful agent such as propofol during daycare surgeries. Lidocaine and ketamine both are used as pre-treatment to decrease propofol induced pain. This study aims to compare the effectiveness of ketamine injection to decrease propofol-induced pain in comparison to lidocaine injection.

Methodology: This is a prospective cross-sectional comparative study. Eighty-nine cases were divided into two groups where group K received ketamine 2 ml (0.2 mg/kg) whereas group L received lidocaine 2% 2ml (0.5 mg/kg) after venous occlusion with rubber tourniquet. One-fourth dose of propofol was injected 1 min after release of tourniquet and pain accessed at 0, 1, and 2 minutes of propofol injection with a verbal response and behavioral signs. Chi-square test and paired T-test were used and a p-value less than 0.05 was considered significant.

Result: Regarding hemodynamic, oxygenation, and adverse effects there was no significant difference. Immediately after propofol injection, only 1 patient of the ketamine group had mild pain (2.22%) while 12 patients from the lignocaine group had mild pain (27.27%) with a p-value of 0.009. Also after 2 minutes of propofol injection, only 12 cases had mild pain i.e. 13.48% (1 from ketamine group i.e. 2.22% and 11 from lidocaine group i.e. 25%) with p-value of 0.002.

Conclusion: Our study helps prove low-dose ketamine is more effective in reducing the incidence and severity of pain on injection of propofol in comparison to Lidocaine with better hemodynamic stability.

Authors: Sulaimankulov Ruslan , Jolochieva Gulmira
Published: June 2021

Introduction: Laparoscopic Cholecystectomy is a standard operative procedure for patients with gallbladder diseases and is the most common laparoscopic procedure performed worldwide. The aim of this study is to analyze the different methods of laparoscopic cholecystectomies done by a single surgeon at Nobel Medical College Teaching Hospital.

Objectives: The objective and aim of this study are comparing 4 port classic Laparoscopic Cholecystectomy (4PLC), 3 port (3PLC) and Laparo-Endoscopic Single-Site Cholecystectomy (LESC) performed by a single surgeon and correlate worldwide experience with outcomes in our institution.

Methodology: The study includes retrospective analysis of 8192 patients who underwent elective laparoscopic Cholecystectomy (LC) from October 2010 to July 2020 performed by the single surgeon. All cases divided into 3 groups depending on the type of LC (4PLC, 3PLC, LESC). The data included the type of the surgery, gender, age, operative time, conversion and complication rate and duration of hospital stay.

Results: The hospital stays, operation time and conversion rate decreased from group I to group III. Female patients out numbered the male ones (M:F=1:4). The hospital stays (3.4 days), operation time (35 min), conversion (0.4%) and complications (0.7%) rate decreased from Group of 4PLC to Group of LESC (1.5 days, 13 min, 0.1% conversion, 0.4% complication respectively) which is true for almost all other similar studies.

Conclusion: The advantages of LESC include a better cosmetic effect and reduced chance of infections. It has been postulated to be superior in scarless surgery with added benefits of lower pain level and reduced need for analgesics, shorter hospital stays, quicker return to work and lower financial expenses.

Authors: Mehta Ram Kumar , Mallick Ram L , Parajuli Surya , Jha Rajneesh
Published: June 2021

Introduction: Hypertension is the most common cardiovascular diseases. In only 5-10 % of hypertensive patients, underlying cause can be identified (secondary hypertension). Serum uric acid is thought to play a pathogenic role in development of hypertension and is also a commonly associated condition in patients with hypertension. Management of hyperuricemia will ultimately help in reducing cardiovascular morbidity and mortality.

Objectives: To determine the prevalence of hyperuricemia among hypertensive patients atiending Birat Medical College Teaching Hospital and also to find association between hyperuricemia and socio-demographic variables.

Methodology: This was a descriptive hospital based cross-sectional study conducted in 168 hypertensive patients at Birat Medical College Teaching Hospital, Nepal for a period of 6 months from 1 September 2020 to 28th February 2021. Sociodemographic variables were recorded and serum uric acid level was obtained based on the pre-structured questionnaires. Data were analyzed by Statistical Package for the Social Sciences version 20 (SPSS 20).

Result: Prevalence of hyperuricemia was 42 (25%) among hypertensive patients with more prevalent in male 33 (30.8%) than female 9 (14.8%). Hyperuricemia was more prevalent in patients having higher BMI and patients aged more than 60 years i.e. 38 (34.5%) and 25 (41.7%) respectively. It was more prevalent among patients with hypertension for more than 15 years 10 (41.7%) and non-vegetarian 33 (25.8%). Hyperuricemia was significantly associated with those aged more than 60 years (p=0.002) and BMI >25 kg/m2 (p=0.002).

Conclusion: Hyperuricemia was common associated condition among hypertensive patients. Hyperuricemia is mainly associated with male gender, non-vegetarian and patients with longer duration of hypertension. Similarly, it was strongly associated with older age and patients having higher BMI. Monitoring of serum uric acid and management of hyperuricemia might be helpful in management of hypertension and thus decreasing cardiovascular morbidity and mortality.

Localization of the scintillation detectors manufacturing process has many benefits because of the high detection efficiency of the detectors, user-friendly, and consistent with general research objectives. Using a photodiode instead of a photomultiplier tube (PMT) allows saving energy, shortening the detector volume, and removing high voltage power supply and amplifier. The combination of CsI(Tl) scintillator, avalanche photodiode, charge sensitive preamplifier, wide range amplifier, and power supply system has been integrated into the detector. This study presents new results in manufacturing a home-made scintillation detector using avalanche photodiode. The detectors of this type can be used in hospitals, in the nuclear laboratory of universities for the students training, etc.

Published: June 2021

Clause 1, Article 33, Decree 03/2021/NĐ-CP dated January 15, 2021, on compulsory civil liability insurance of motor vehicle owners, clearly regulate the responsibility of insurance companies in developing and operating information technology system to guarantee statistical affairs and update the implementation of compulsory civil liability insurance of motor vehicle owners to ensure the connection to database on compulsory civil liability insurance of motor vehicle ownersas well as responsibility for insurance companies to provide minimum information on the system. However, in reality, insurance companies use their own database systems and hesitate to share information on the common database,thus causing difficulties for management. This issue leads to difficulties in data management and sharing. A cause of this situation is that insurance companies worry about the risk of losing customers when information is public. In order to resolve this issue, the paper will analyse a model that has been successfully deployed in Korea, from which, proposes several recommendations to contribute to the early realisation of the national insurance databases in Vietnam.

Published: June 2021

The aim of this study was to establish whether there are differences between weight categories in different anthropometric measurements and handgrip strength between elite Serbian male and female sambo athletes divided into weight categories. A total of 70 elite Serbian sambo athletes participated in the study, who were participants of the World Cadet Sambo Championship held in Novi Sad. Athletes are classified into categories according to gender and official weight categories. Using anthropometry, we calculated somatotypes and hand-grip strength. For statistical analysis, we used a one-way analysis of variance and Tukey’s post hoc tests to compare group differences by weight categories. Somatotype analysis shows that a typical somatotype in male sambo athletes was endomorphic mesomorphs. In female groups, the most common somatotype in the lightest categories was mesomorphic ectomorphs, and in the heaviest categories were endomorphic mesomorphs. Examining the handgrip for both left and right hand, as well as in total, shows that there is a statistically significant difference between the categories. In total, the strength of the handgrip increases progressively in groups. In male categories, the difference exists between the first 4 groups and -78kg, as well as between -42kg and -46kg and the heaviest weight category. Differences between weight categories in female athletes were found between the lightest group and last six groups in total, in favor of the last six. Anthropometric measurements revealed a statistically significant difference between weight categories. Mesomorphy was the most dominant somatotype in male categories, while female athletes differed concerning weight category. The achieved results can serve as data to compare the somatotype and handgrip strength of elite sambo athletes on a national and international level. These findings suggest that the handgrip strength and somatotypes are the keys to success in relation to the weight category.

Abstract This study’s objective was to analyze the relationship between mental toughness and martial artists’ performance strategies. Two hundred athletes (male: 105, female: 95) with an age range of 18-36 years (mean:25.12, s=4.96) who competed at university to the national standard of martial arts participated in this study. Participants answered mental toughness questionnaires and performance strategies inventory. The Pearson correlation results showed a positive and significant relationship between mental toughness and automaticity, goal-setting, imagery, self-talk, and emotional control, and a negative and significant relationship between mental toughness and attentional control in practice. Furthermore, there is a positive and significant relationship between mental toughness and activation, relaxation, self-talk, imagery, goal-setting, and emotional control in the competition. The multiple linear regression analysis results showed that goal-setting and imagery in practice and competition, self-talk in practice, and relaxation in the competition could predict mental toughness. In analyzing the subscales of mental toughness, it was concluded that tough emotions could be loaded on eight subscales of performance strategies. In the Independent-Sample T-Test, the significant differences related to gender were that men reported higher levels of self-talk (t=3.24, p<0.001), automaticity (t=2.76, p<0.006), goal-setting (t=2.63, p<0.009), imagery (t=2.18, p<0.03) and relaxation (t=2.17, p<0.03) than women.

The evolution of basketball made the game faster, leading coaches to increase the use of pick and roll cooperation in offense. The purpose of this research was to investigate the performance time of the pick and roll every five minutes, the pair of players who participated in the pick and roll and the offensive action of the ball handler after the screen, in the European Men's Championship of 2017. The sample of the research was the sixteen games of the second round of the Championship. The instrument used for the analysis of the matches was the SportScout STA Version 3.2. Analysis with ꭓ2 (Chi-square) was used. In the results analysis, a total of 714 screens were found, of which 356 were successful (49.9%) and 358 (50.1%) failed. Most pick and rolls were performed in the second five-minute span of the third period of the games (14.8%) and in the first five-minute span of the first period (14.1%). Regarding the pairs of players participating in the action, most of them had the guard as the ball handler and the center as the screener (63.4%). In about 60% of the pick and rolls the ball handler chose to finish the action himself either by driving to the basket (31.8%) or with a shot (28.6%). The results of this study provide more information and directions to basketball coaches in order for them to better organize their training and maximize the offensive performance of their teams.

El objetivo de este estudio es analizar las relaciones y los discursos que genera el lector desde un enfoque didáctico de literacidad al interactuar en paralelo con el autor y su propuesta literaria enmarcada en un modelo cultural específico. El estudio sigue un paradigma cualitativo basado en una perspectiva etnográfica del análisis del lenguaje empleado por los sujetos para reaccionar y construir significados vinculados a la experiencia de aprendizaje. Se analizan los productos generados por 20 maestros en formación en el área del idioma inglés que convivieron con un escritor chicano. Se encontró que cada lector fue capaz de interpretar y dar sentido a la actividad a través de diversos géneros de escritura. Los estudiantes establecieron una conexión personal con el autor que permitió un intercambio de emociones, recursos lingüísticos e interpretaciones que atribuyeron un valor significativo al entendimiento cultural. Se concluye que el enfoque de literacidad coadyuvó a la formación de lectores críticos y creativos dispuestos a vivir la experiencia de transformar sus propias ideas y creencias.

İnsan beyni çoğu zaman bilinç düzeyinde çalışmaktansa bilinçdışı düzeyde faaliyet göstermeyi tercih etmektedir. Böylece enerjiden tasarruf ederek birçok farklı işi daha doğru ve daha hızlı gerçekleştirebilmektedir. Beynimizin bilinçaltı düzeyde çalışması her ne kadar doğal bir süreç olarak değerlendirilse de, sistemin bu yapısından faydalanıp insanları manipüle eden oluşumlara karşı bilinçli zihni devreye sokmak büyük bir önem arz etmektedir. Bu doğrultuda araştırma, sanal görüntüler üzerinde bilinçli olarak uygulanan glitch tekniği ile oluşturulacak hataların, deformasyonların ve aksaklıkların zihni bilinçaltı etkilerden kurtarabilecek algısal bir kırılma anı yaratabileceğine vurgu yapmaktadır. Dijital ile yapılan manipülasyon, kültürel değerleri değiştiren, bilinç kullanımını körelten, algı operasyonuna yönelik yapısıyla karşımıza çıkmaktadır. Özellikle dijital kültür etkisindeki çağda sanal olanın hâkimiyeti, algı yönlendirmelerine gerekli zemini sağlamaktadır. Sanal ile gerçek arasındaki çizginin giderek inceldiği günümüzde tekno-kültürü benimseyen toplum, hegemonik ideolojiler altında konformist yaklaşım sergilemektedir. Farkında olmadan bizi yönlendiren etkilerin, bilinçli bir şekilde algılanabilirliği üzerine incelemeler yapılan bu çalışmada, bilinçdışı yönlendirmenin varlığına ve konformist bir yapıya bürünmemek için sorgulamanın önemine dikkat çekmek amaçlanmaktadır.

Seramiğin kullanımı, insan kültürünün bir parçası olarak binlerce yıldır süregelmektedir. Renk de neredeyse seramiğin kullanımı kadar eski bir kültür öğesidir. Seramikler üzerinde bilinçli olarak kullanımı görülen ilk renk olasılıkla kırmızıdır. Bu rengin güçlü bir sembolik öneminin olduğu, binlerce yıllık mağara resimlerinde ve farklı kültürel alanlardaki kullanımında görülmektedir.
Araştırmada insanlığın kırmızı renge ulaşmaya çalışırken, ana renk olan kırmızının turuncu, kahverengi, pembe, bordo, mor, vb. gibi ara tonlarını da dahil ettiği saptanmıştır. Araştırma kapsamında kırmızı renge ulaşma yolları açıklanırken bir ana renk olan kırmızının yanında kırmızının ara renk ve tonlarına da yer verilmiştir.
İnsanlığın seramik yapımında kırmızı rengi neden kullandığı sorusu ile yola çıkılarak, bu renge ne gibi kültürel anlamlar yüklediği ve renk kullanımındaki sembolik dil incelenmiştir. Daha sonra bu rengin nasıl elde edildiği, yani teknolojisi nedir? sorusu sorulmuştur.
Rengin ortaya çıkmasını sağlayan malzeme özellikleri, tarihsel süreçte gözlenen farklı teknolojik aşamalar ve rengin elde edilmesinde kullanılan teknikler hakkında bilgi verilmiştir.
Bu doğrultuda, seramikte çamur renklendirme, yüzey renklendirme, sır ve alternatif pişirim gibi farklı tekniklerle kırmızı elde etme yöntemleri anlatılmıştır.

Protrusion acetabuli is the medial protrusion of the acetabulum in to the pelvic cavity, also known as arthrokatadysis, more common in females and classified etiologically as primary (idiopathic) and secondary forms. This is a 66-year-old female patient that presented for a plain radiograph of the pelvis and hip joints from a peripheral healthcare center on account of pain and inability to stand and move her waist and hips bilaterally, reduced movement of the legs and pain in the knees for more than three-year duration of onset. The plain radiograph of the pelvis and both hip joints demonstrate reduced density of the demonstrated bones, medial protrusion of the medial wall of the acetabulum in to the pelvic cavity bilaterally (distance between the imaginary Kohler’s line and medial acetabular wall is about 22mm bilaterally; Degree: III), obliteration of the hip joints bilaterally, thickening and sclerosis of the acetabular walls and other articular margins, subarticular cysts on the femur, acetabulum and pelvic bones. The patient had no coexisting condition like rheumatoid arthritis, Marfan’s syndrome and psoriatic arthritis. A diagnosis of bilateral idiopathic protrusio acetabuli was made. The patient was advised on bilateral total hip arthroplasty to improve the symptoms. We report a case of bilateral idiopathic protrusion acetabuli in an elderly female patient in order to describe the features of this condition radiographically.
