Background: Adolescence is a developmental period when adverse childhood experiences significantly impact the individual because of the changes in brain structure and functioning. This research aims to investigate the relationship between maltreatment and emotion regulation with the moderating role of cognitive flexibility in adolescence with childhood trauma. Methods: This was a descriptive-correlational study. The study population consisted of all adolescents who were referred to the psychological and psychiatric disorders clinics and medical clinics of Shiraz City, Iran, in the spring semester of 2021. The population included 250 individuals, of which 175 were selected as the sample of the research via the simple random sampling method according to the Morgan Table. The research tools were the childhood trauma questionnaire, the cognitive flexibility questionnaire, the psychological maltreatment scale, and the emotional regulation scale. After completing the questionnaires, the data were entered into the SPSS software, version 23, and analyzed using descriptive and inferential statistics. The Pearson correlation test and the regression method were used to analyze the data. Results: The results showed a significant negative correlation between maltreatment with emotion regulation (r=-0.531, P<0.001). The results showed that the interaction of these 3 variables indicated that cognitive flexibility has a moderating role in the relationship between maltreatment and emotional regulation (β=-0.90, P<0.01). Moreover, the results indicated that the relationship between maltreatment and emotion regulation in adolescence with high flexibility is higher than in individuals with low flexibility. Conclusion: This study provides evidence that cognitive flexibility can act as a moderator when considering the impact of trauma. The developed task could provide a novel way to assess this flexibility within an emotional context.

Background: Informal caregivers of COVID-19 patients, who are in direct contact with patients and the virus, experience many psychological issues and are prone to Illness Anxiety Disorder (IAD). Accordingly, this study aims to determine the effects of virtual training of the Benson Relaxation Technique (BRT) on IAD in the informal caregivers of COVID-19 patients. Methods: This randomized clinical trial study was conducted on 54 informal caregivers of COVID-19 patients who scored X ≥20 on the health anxiety inventory (HAI) by Salkovskis. They were randomly divided into control (n=28) and intervention (n=26) groups. The intervention group received the BRT audio file and pamphlet through messengers, and applied this technique twice a day, each for 20 min, for 3 weeks. However, the control group did not receive any training. Subsequently, after 3 weeks, HAI was completed by both groups again. Data analysis was done using SPSS software, version 22. Results: The mean score of IAD in the informal caregivers of the patients before the intervention in the experimental and the control groups was 24.88±5.89 and 23.27±5.64, respectively. After the intervention, the mean score of the IAD in the informal caregivers of the patients in the intervention and the control groups changed to 17.30±7.15 and 19.78±7.14, respectively. The result of the t-test showed a significant difference between the changes in the IAD scores of the two groups after the implementation of the intervention (P=0.046). Conclusion: The findings show that the virtual training of BRT, as a comprehensive, simple, and inexpensive method, reduces IAD in the informal caregivers of COVID-19 patients. The healthcare systems can take steps to support these people who are exposed to IAD by providing virtual training of BRT to informal caregivers of COVID-19 patients.

Background: Previous experiments have shown different responses of pancreas and liver cells to the culture medium. It has been revealed that the most important step in preserving primary pancreas and liver cells is selecting the appropriate supplements to support the viability and functionality of these cells. Materials and Methods: Cultivation supplements were prepared by adding bilirubin, hemin, zinc protoporphyrin, glutathione, curcumin, and their combination in the pancreas and liver cell culture at a concentration of 1, 3, and 5 μM. Then, the survival rate and function of the pancreas and liver cells were evaluated. The function of pancreas cells was evaluated based on producing insulin and the function of liver cells was based on liver enzymes, including transaminases. Results: We found that bilirubin, hemin, zinc protoporphyrin, curcumin, glutathione, and their combination as supplements can dose-dependently maintain pancreas and liver cells viability and functionality proven by increasing insulin secretion levels and transaminase enzyme activity. The strength of effects is displayed in the following order: bilirubin > combination of all compounds > hemin > zinc protoporphyrin > curcumin > glutathione. Conclusion: This study shows that these compounds are suitable supplements with special biochemical properties. They provide optimal supplements for the culture media of pancreas and liver cells. They may fulfill a function in the antioxidant protection of pancreas and liver cells.

‘Decolonizing’ citizenship learning with international students
Authors: Perry J. Adam , Bethune L. Rachael
Published: March 2023

This article explores the possibilities for decolonizing approaches to inter-cultural learning for international students in Canada. In this article the authors present the findings from a series of photovoice workshops conducted as a part of a larger mixed-methods project that explores how informal and everyday pedagogies shape international students’ mobility decisions in the Atlantic Canadian province of Nova Scotia. Participants’ collaborative analysis of their own photographs reveal how everyday citizenship learning emerges from international students’ affective relationships to place in such a way that obscures how international education is implicated in processes of settler colonialism. However, evidence suggests that participants’ sense of belonging is deeply implicated in their connections to place, highlighting potential opportunities for integrating international students in current initiatives to “decolonize” higher education in the Canadian context.
INFLUENCE OF THE AMBIENT TEMPERATURE ON THE MECHANICAL TENSION OF THE OPTICAL CABLE
Authors:   State University of Intellectual Technology and Communications, Kiforuk S. V.
Published: March 2023

To ensure the quality and reliability of the fiber-optic communication line during the exploitation, it is necessary to constantly monitor the technical condition of the optical cable (OC), first of all, the tension in the fiber. Mechanical tensions in the optical fiber due to macro- and microbends lead to a change the signal’s attenuation coefficient. Therefore, the study of the effect of the temperature of the operating environment of the optical cable on its mechanical tensions is relevant. The purpose of the work is to determine the mechanical stress of the dielectric optical cable as a function of the temperature change (tx) at constant values of the tension in the cable, which correspond to the corresponding elongation of the cable (εр). The article investigates the effect of ambient temperature on the mechanical tensions in the cable (σ0x). Conducted on the example of a cable type OKL-3-D1 of the domestic manufacturer "Odeskabel" with a dielectric central power element made of fiberglass of the "Polystal" type, and a peripheral power element – made of aramid threads "Twaron 2200-1055". An estimate of the mechanical tension in this OC was obtained at different temperature values from -40 °C to 60 °C and at different elongations. For this purpose, the values of the temperature coefficient of linear expansion, Young’s modulus of such a cable were obtained in the work. In the studies, the values of constant tensile loads of the cable, which correspond to its elongation from 0.2 % to 0.6 %, were used. According to the results of the study, at a constant mechanical load of a given type of cable, which corresponds to its certain elongation εр = 0.6 %, a decrease in mechanical tensions up to 7 % was obtained. Due to the fact that the mechanical stress in the optical cable consists of two parts, the first of which depends on the mechanical loads, and the second depends on the temperature change of the cable's operating environment. According to the work [2], the first component is much larger than the second, but its changes, established in this work, in critical situations for fiber-optic communication lines are of significant importance, which must be taken into account during the design and operation of lines. In general, the study of σ0x made it possible to establish that the mechanical stresses of the OC de crease with temperature increase due to the negative temperature coefficient of linear expansion of the aramid threads.

Анотація. У статті дана характеристика колабораційній діяльності як складової суспільно-психологічного явища добровільної, нерідко на ідейно вмотивованої співпраці з агресором у всіх сферах суспільного життя, результатом якої є підрив національної безпеки України, створення загрози державному суверенітету, територіальній цілісності, конституційного ладу та іншим національним інтересам держави. Здійснено аналіз та походження поняття колабораціонізм, його періоди розвитку, ідея якого зводились до того суспільно-психологічне явище, що виникає в результаті взаємодії цивільного населення з агресорами на тимчасово окупованій території. Вивчено зміст статті 111-2 КК України – «колабораційну» діяльність, внесеного Законом України «Про внесення змін до деяких законодавчих актів України щодо встановлення кримінальної відповідальності за колабораційну діяльність». Аналізуючи ознаки нормативно – правові акти, встановлено, що сучасне поняття «колабораціонізм» змістовно охоплює особливі форми державної зради передбаченої ст. 111-2 КК України (військове, політичне, економічне, адміністративне, культурне, інформаційне, медійне співробітництво) громадянина України з державою-агресором або її представниками та створеними чи підтримуваними нею незаконними збройними формуваннями, яке завдало шкоди державному суверенітету, територіальній цілісності та недоторканності, обороноздатності, державній, економічній чи інформаційній безпеці України. Це доводить, що в сучасних умовах ведення повномасштабної війни з російською федерацією, колабораціонізм як суспільно – небезпечна протиправна діяльність має кримінально – правові форми, які встановив законодавець, а саме: безпосередня участь у збройному конфлікті на боці держави-агресора; публічні заклики, що спрямовані на підтримку чи безпосереднє співробітництво з державою-агресором; організація та проведення під контролем держави-агресора виборів на окупованій території, проведення будь – яких референдумів, організація та участь у проведенні інформаційних компаній, що спрямовані на забезпечення підтримки держави-агресора; добровільний вступ на посади в органах, самопроголошених чи створених державою-агресором державних утворень; передача матеріальних та нематеріальних ресурсів регулярним військам держави-агресора тощо.

Published: March 2023

The purpose of this article is to analyze the dynamics of technology use in the Ukrainian economy during 2013-2020 in order to identify fluctuations that determine the vector of development of the country's technological sphere in the context of its ability to self-organize. As a term of synergetic theory, fluctuations are defined as the deviation of parameters from the general trend. Special aggregates according to Commission Regulation (EC) No 251/2009 of 11.03.2009 by the level of technology use were the object of this study. The technological imbalance index of the national economy and Theil indices separately for manufacturing and services were calculated. Both indicators were based on the amount of added value per employee. The analysis of the dynamics of these indicators showed a high level of imbalance of the technological sphere in terms of employment efficiency. The analysis of the dynamics of these indicators showed a high level of imbalance in the technological sphere in terms of employment efficiency. Quantitative fluctuations with signs of cyclicity over a period of about three years were detected. Structural fluctuation is associated with the leadership of the service sector in the use of labor resources compared to the production sector. The detected fluctuations are characterized as a manifestation of the nonlinearity of the development of a complex open techno-system of the country. The conclusion is made about the role of digitalization of the economy as an attractor that determines the main goal of the system development for the long term. This attractor is able to "push" the transformation processes in the direction of increasing the cumulative effects of the interaction of system elements and strengthening its ability to self-organize. The system of economic policy measures, taking into account the target orientation of economic development towards digitalization was proposed. The author emphasizes the fact that digitalization provides many opportunities for both increasing employment level and improving the educational and qualification level of employees and developing a culture of communication between citizens, business and the state. The synergistic effects of digitalization in the field of employment are also manifested in the unification of IT competencies, unidirectionality of personal, collective, state, and public interests, and increased interaction between business entities.

Can melatonin improve the alteration of protein synthesis occurring in schizophrenia and bipolar disorder?
Authors: Coto-Montes Ana , Menendez-Coto Nerea , Boga Jose Antonio
Published: March 2023

The prevalence of mental illnesses has significantly increased globally in recent decades due to multifactorial causes. Of these, schizophrenia and bipolar disorder, due to their high incidence and high associated disability, stand out. However, the effective treatments on these disorders are lagged behind their increased incidence. Melatonin, as an essential molecule in the regulation of sleep-wake rhythm and the naturally occurring antioxidant, has only received attention for the treatment of such psychiatric disorders in relation to its circadian rhythm regulation, but its overwhelming role as a regulator of oxidative stress that facilitates the amelioration of neuronal damage has not been addressed for this respect. In this communication, the novel aspects of melatonin on mental illnesses have been discussed. We provide the necessary literature to justify the beneficial roles and the mechanisms of melatonin to treat schizophrenia and bipolar disorder. These mechanisms include that melatonin enhances reticulum stress, potentiates the unfolded protein response, and increases endoplasmic reticulum synthesis to facilitate autophagy and even suppresses apoptosis. This process involves not only the expected organelles but is a more complex cohesion that even includes the mitochondria, a well-known target of melatonin, which reinforces the robustness of our hypothesis, i.e., melatonin prevents the development of protein aggregates and abnormal structures typically observed in brain damage. Its documented capacity and the need to improve treatment efficiency in a growing population afflicted by mental illnesses are the basis of this hypothesis and support a role of melatonin, as antioxidant, in psychiatric disorders.

Published: March 2023

Ziziphus mauritiana is a plant species belonging to the Rhamnaceae family. It is commonly found in tropical and subtropical regions of Asia, and in Indonesia, this plant grows wild and thrives on the islands of Bali, Lombok and Sumbawa. The fruits of Z. mauritiana are edible, however, in Indonesia, it is underutilized and has very low economic value. To evaluate its possibility to be developed as a functional food, this study was conducted to determine the total phenolics and flavonoids, dietary fiber, and nutrients contained in the fruit juice of Ziziphus mauritiana. Total phenols and flavonoids contents were determined using Folin Ciocalteu and AlCl3 methods, respectively. The in vitro antioxidant activity of the juice was evaluated using the DPPH method. The content of soluble and insoluble dietary fiber was determined using the standard AOAC analysis method, and proximates analysis was conducted in accordance with SNI 01-2891-1992.  The results of this study revealed that freeze-dried juice of Z. mauritiana fruit has total phenols content of 1690 mg GAE/100g, total flavonoids of 15.10 mg QE/100g, soluble dietary fiber of 0.61%, and insoluble dietary fiber 2.03%. However, the antioxidant activity of Ziziphus mauritiana fruit juice was weak with IC50 328.54 ppm. The proximate analysis revealed the crude fiber in the freeze-dried fruit juice was 0.56%, carbohydrates 82.43%, protein 3.34%, fats 0.31%, ash 3.62%, and water 10.30%. In conclusion, Ziziphus mauritiana fruit juice has a high content of total phenolic substances, high dietary fiber, and high nutritional value, therefore it has a good potential to be developed as a functional food.
Multi-objective Optimal Power Flow and Emission Index Based Firefly Algorithm
Authors: Mezhoud Nabil
Published: March 2023

The economic operation of electric energy generating systems is one of predominant problems in energy systems. In this work one evolutionary optimization method, based on the meta-inference behavior called the Firefly Algorithm (FFA) is applied to solve such as the multipurpose optimum power flow (OPF) and emission index (EI) problems. Our main goal is to improve the objective function necessary to achieve the best balance between production and its energy consumption, which is presented as a non-linear function, taking into account some constraints of equality and inequality. The goal is to reduce the total cost of generations, active losses, and emission index.The FFA approach was examined and tested on a standard IEEE-30 bus system. The validations of obtained results were compared with some well-known and recently published references. The efficiency and credibility of the proposed method has been proven by the obtained results.
Marjo Lindroth and Heidi Sinevaara-Niskanen, The Colonial Politics of Hope: Critical Junctures of Indigenous-State Relations (London: Routledge, 2022)
Authors: Fusco Sara
Published: March 2023

The main theme is “hope“. The authors trace the sources of this concept to the colonial era in which the only “hope” for Indigenous peoples to survive was integration into Western society. The empirical and conceptual analysis of hope follows three thematic paths: the constitutional recognition of indigenous rights, the ratification of ILO Convention 169, and the creation of self-governments such as the one established in Greenland in 2009. The decolonization process by the Nations Unite began in 1960, when several declarations were stating that “natural heritage and political determination belong to all individuals”. These rights were not to be influenced by diplomatic relations between states and were to be respected in all member states. As the book points out, not all states adopt the new provisions easily. Since the declarations of the General Assembly are not legally binding, in the 1970s the International Covenant on Civil and Political Rights (ICCPR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR) came into force. Even today, these conventions play a role of absolute importance in disputes involving cases of inequality, discrimination, and racism.
Philip E. Phillis, Greek Cinema and Migration, 1991–2016 (Edinburgh: Edinburgh University Press, 2020)
Authors: Tagliaferri Viviana
Published: March 2023

With this engaging work on the contemporary filmic representation of migration by Greek cinema, Philip Phillis enters significantly into the hotly debated the issue of migration en masse to Europe of the last decades, doing so with an approach that is both artistic and historical. In focusing on the border crossings that have particularly affected the geopolitical space of the Greek peninsula over the last thirty years, the author succeeds in proposing a thorough outlook to the migratory question through the analysis of its cinematic portrayals by Greek filmmakers or filmmakers active in the Greek area from 1991 to 2016. In fact, through a sensitive and intelligent operation, Phillis sets issues of a purely cinematic nature alongside an eminently political analysis, developing these in parallel throughout the book. This dual nature of the discourse is masterfully held together through the careful — and never superficial — descriptive analysis of the films covered and the ability to compare the poetics of the various directors with the need to re-give voice to migrants and refugees. In fact, Phillis, while praising many directors in his book, seems never to lose sight of the fact that “Greek immigration cinema is produced from a hegemonic position of enunciation since relevant power structures empower indigenous filmmakers rather than the migrants represented on film” (p. 11).

Authors: Salamon Justyna
Published: March 2023

The aim of the research is to show the impact of religion, in this case Islam, on the finances and functioning of enterprises in the region of North Africa and the Middle East (MENA). The key issue is to answer the question whether religion can be decisive for the organisational structure and directly affect the decision-making process within an enterprise.

The first objective of the article was to determine what makes Polish companies decide to issue bonds (instead of financing themselves with loans or other sources). The second objective was to examine the key factors determining the interest rate of bonds. The research was based on public bonds, listed on the Polish Catalyst bond market. It should be emphasised that this is the first study of this kind on the Polish bond market covering both the issue characteristics and the financial attributes of the issuers. Firstly, in order to determine which parameters have a real impact on Polish companies’ issuance decisions, a probit model was created basing on parameters such as the age of the company, its size, asset growth dynamics, leverage, ROA, and investments in fixed assets.Secondly, in order to determine what the real interest rate of the bonds depends on, using linear regression and the least squares method, we examined the key parameters that issuers could consider as leading in determining the future estimated interest rate of the bonds, such as rating, issue collateral, issue size, and maturity.In our research we found that the size of a company and the level of its financial leverage are the main incentives for Polish companies to issue bonds. Moreover, the size of the issuer and the level of its financial leverage are the key factors determining the bonds margin.

Analysis of errors in the writing of content in dissertations and their impact on the learning of foreign languages: A case study in Ghana
Authors: Fenyi Daniel Arkoh , Morrison Richard
Published: March 2023

The average postgraduate student in Ghana has about 20 years exposure in English language, having been taught and instructed in English from primary to tertiary level. It is, therefore, not far-fetched to expect the postgraduate student to commit minimal to no errors in their L2 writings. The seeming consequential minimal scholarly attention on errors in postgraduate writings regardless of the many studies on students’ errors is therefore not surprising. This study is an attempt to identify, categorise and describe the errors in postgraduate dissertations in Ghana and highlight its implications for language teaching. This exploratory qualitative study carries out a content analysis of 20 randomly selected MA, MPhil and PhD dissertations published between 2020 and 2021. The data are analysed using the theory of Error Analysis. After critically assessing the dissertations, seven (7) categories of concord errors were identified and recorded. These are; subject-verb concord errors, inverted subject concord errors, concord errors associated with ‘has’ and ‘have’, determiner-noun errors, concord errors on numbers, noun-pronoun antecedent errors and compound subject concord errors. This implies that postgraduate students are prone to errors, hence, the need to introduce or intensify the teaching of English at the postgraduate level.

ROK-US Conflicts during the Early Cold War: Focusing on the Syngman Rhee Administration and the US before the Signing of the Calcutta Agreement in 1959
Authors:   Korean Association For Political And Diplomatic History, Kang Yeo-rin
Published: March 2023

This study analyzes the policy of the Syngman Rhee administration and the US policy before the Calcutta Agreement in August 1959 concerning the Repatriation of Koreans in Japan to North Korea. This paper’s question is, ‘How did the ROK-the US conflict develop before the Calcutta Agreement in August 1959 regarding the Repatriation of Koreans in Japan to North Korea?’ This study suggests two answers. First, the Syngman Rhee administration misunderstood the International Committee of the Red Cross, acted independently and had difficulty communicating with the US. Second, the US made various efforts to make the Syngman Rhee administration aware of the reality to prevent the deterioration of the ROK-Japan relations due to the progress of the Repatriation of Koreans in Japan to North Korea. The conflict between the ROK and the US became severe from late June to July 1959. On August 13 of the same year, the Calcutta Agreement between the Japanese Red Cross and the North Korean Red Cross was signed.
