Digital Communication Channels in Export Transactions of Polish Enterprises in The Conditions of The COVID-19 Pandemic
Authors:   Uniwersytet Ekonomiczny w Katowicach, Talar Sylwia
Published: March 2023

Purpose – The article aims to identify the relationship between the communication shock caused by the COVID-19 pandemic, the digitalization of communication channels in the transaction process, and the exports of Polish enterprises. Research method – The following methods are used: descriptive statistics, correlation analysis, and non-parametric one-way analysis of variance (Kruskal-Wallis test) based on data from a diagnostic survey conducted on a representative sample of Polish exporters. Results – The communication shock caused by the restriction of face-to-face meetings with foreign counterparties had, among many factors, the most negative impact on Polish enterprises’ export transaction opportunities during the pandemic. However, hypotheses that there are relationships between export performance, export opportunities and the use of digital communication channels, and the digitalization of communication under pandemic conditions were rejected. The absence of such relationships refers to Solow’s paradox of the lack of efficiency effects of digital technologies implementation. Originality / value / implications / recommendations – Conclusions enhance knowledge of the digitalization of international economic transactions, and in particular, the efficiency of the uti-lization of digital communication channels in export transactions under pandemic conditions.
Extreme hyperferritinemia in restrictive type anorexia nervosa
Authors: Amanoal Christine Hvolby , Nielsen Lene Kongsgaard , Thomsen Henrik Holm
Published: March 2023

Iron metabolism and markers hereof are altered in anorexia nervosa (AN) but far from completely understood. We report a case of extreme hyperferritinemia in a patient with AN and discuss the possible mechanisms and current knowledge about the association between hyperferritinemia and AN. A 20-year-old woman with a history of AN presented with bradycardia, weariness, and malaise in addition to an incidentally very high ferritin level. The symptoms disappeared spontaneously after a short admission. There were no signs suggestive of systemic, hematological, or malignant disease causing the very high concentration of ferritin. Her body weight was in decline, leading up to admission, but did initially increase after discharge accompanied by declining ferritin concentration. However, a clear association between ferritin dynamics and weight changes or physical activity was not identified and neither were other causes of the hyperferritinemia. Around one in four patients with AN have increased ferritin concentrations. Our case represents the highest ferritin concentration reported in a patient with AN without other underlying causes or comorbidities.

Learning points

Perturbed iron metabolism is frequent in restrictive type anorexia nervosa but incompletely understood.

Altered ferritin in anorexia nervosa may be linked to nutritional status.

Mesenteric metastases in small intestinal neuroendocrine tumors (SI-NETs) are associated with mesenteric fibrosis (MF) in a proportion of patients. MF can induce severe abdominal complications, and an effective preventive treatment is lacking. To elucidate possible novel therapeutic targets, we performed a proteomics-based analysis of MF. The tumor cell and stromal compartment of primary tumors and paired mesenteric metastases of SI-NET patients with MF (n = 6) and without MF (n = 6) was analyzed by liquid chromatography-mass spectrometry-based proteomics. Analysis of differential protein abundance was performed. Collagen alpha-1(XII) (COL12A1) and complement component C9 (C9) expression was evaluated by immunohistochemistry (IHC) in mesenteric metastases. A total of 2988 proteins were identified. Unsupervised hierarchical clustering showed close clustering of paired primary and mesenteric tumor cell samples. Comparing MF to non-MF samples, we detected differentially protein abundance solely in the mesenteric metastasis stroma group. There was no differential abundance of proteins in tumor cell samples or primary tumor stroma samples. Analysis of the differentially abundant proteins (n = 36) revealed higher abundance in MF samples of C9, various collagens and proteoglycans associated with profibrotic extracellular matrix dysregulation and signaling pathways. Proteins involved in fatty acid oxidation showed a lower abundance. COL12A1 and C9 were confirmed by IHC to have significantly higher expression in MF mesenteric metastases compared to non-MF. In conclusion, proteome profiles of SI-NETs with and without MF differ primarily in the stromal compartment of mesenteric metastases. Analysis of differentially abundant proteins revealed possible new signaling pathways involved in MF development. In conclusion, proteome profiles of SI-NETs with and without MF differ primarily in the stromal compartment of mesenteric metastases. Analysis of differentially abundant proteins revealed possible new signaling pathways involved in MF development.
Preparation, application, and mechanism of starch modified dicyandiamide formaldehyde polymer–bentonite microparticle retention and drainage aid system
Authors: Zhang Heng , Yang Hongyan , Lu Junliang , Wang Zhe , Gao Hongkun , Liang Chen , Sun Yanhui
Published: March 2023

Modified dicyandiamide formaldehyde polymer (MDDF) and calcined bentonite were used to produce a MDDF-bentonite microparticle retention system. The authors investigated its retention, drainage-aid effect, and its mechanism through measuring the pulp charge density, particle size of the fine particles, and other factors. The results revealed that under neutral conditions and the addition of 0.08% MDDF and 0.3% bentonite, the initial floc was broken via high-speed shearing. Meanwhile, the inorganic filler was added, and the retention effect of the MDDF-bentonite system was close to that of the cationic polyacrylamide (CPAM)-bentonite system. The MDDF-bentonite system exhibited a patch-bridging mechanism. First, the authors added cationic polymer to form a sizeable initial floc, which was then dispersed at high shear force. Then, the authors added inorganic fillers with opposite charges. A smaller floc with more compact structure reformed and was distributed on the wet paper sheet so that more fillers and fine fibers remained on the paper, thus improving the retention efficiency. Because the charge density of MDDF is higher than that of CPAM, the addition of MDDF enabled the pulp system to become closer to the isoelectric point, and the drainage effect was better than that of CPAM.

Authors: Lei Lirong , Cai Fangrui , Wang Caimeng , Li Youming , Li Guangsheng
Published: March 2023

As a great amount of chemicals are employed to carry out the coating process of paper, the wastewater from paper mill making coated products is characterized by high levels of chemical oxygen demand (COD), colour, and total suspended solids (TSS). In this study, wastewater from a paper mill making coated products was treated by a sequencing batch biofilm reactor (SBBR) after a lab-scale coagulation, resulting in COD, colour, and TSS removal efficiencies of 87.7 ± 1.0%, 33.5 ± 5.2%, and 41.4 ± 3.7%, respectively, which exceeded the biological treatment performance in the paper mill. The removal of COD and colour was attributed to the removal of recalcitrant organic matter, and the removal of TSS was attributed to the biofilm.
Study on terpenoid degradation of Pinus massoniana sawdust for mycelium germination and cultivation of edible fungi
Authors: Zhang Jinping , Ying Yue
Published: March 2023

The material basis and degradation of the terpenoids were investigated in Pinus massoniana sawdust during the composting process. In order to better utilize P. massoniana sawdust for the culturation of edible fungus, three treatments were designed according to the amount of brown sugar that was added: 4% (A1), 5% (A2), and 6% (A3). The brown sugar was added based on the dry weight of the P. massoniana sawdust. The results showed that the brown sugar addition of 5% yielded the fastest heating rate of composting and the longest temperature duration above 60 °C. The gas chromatography-mass (GC-MS) analysis showed that the amount of brown sugar did not affect the degradation of the terpenoids. The relative terpenoid content decreased from 3.89% to 2.10% and 0.31% after 30 d and 60 d of composting, respectively. Fourier transform infrared (FTIR) analysis indicated that the terpenoids decomposed a lot throughout the composting process. The mycelium cultivation demonstrated that the P. massoniana sawdust treated with 30 d of composting promoted the growth of edible fungi.

Authors: KHMELEVSKA OKSANA
Published: March 2023

This article is devoted to the study of humanitarian action of the international and national actors in Ukraine. The urgency of the work is driven by the deepening of the humanitarian crisis against the background of the continuation of the active phase of the Russia-Ukraine war. The purpose of the article is to generalize the contextual changes of humanitarian action in Ukraine, including institutional, sectoral, managerial and other aspects. The novelty of the study consists in the formulation of proposals for the activation of humanitarian action in Ukraine at the national and local levels, which are rethought through the prism of the international humanitarian system and the features of humanitarian response in Ukraine. The desk research of open sources which is supported by a review of the latest thematic publications, operational summaries, data sets and their analysis is used for this purpose. An overview of the modern international humanitarian system, the main tools and mechanisms of humanitarian response is provided. International and domestic categorical apparatuses in the field of humanitarian action are compared. New dimensions of the humanitarian crisis, systemic challenges and operational problems of humanitarian response that arose after February 24, 2022 in Ukraine are summarized. The funding for humanitarian needs of Ukraine over the past decade has been analyzed, including interagency response plans for Ukraine for 2022 (the Flash Appeal and the Regional Refugee Response Plan). The humanitarian response at the international and national levels has been studied. It has been concluded that humanitarian action in Ukraine is based on reliable tools, mechanisms and models of the international humanitarian system, as well as on its own humanitarian traditions and initiatives. Together, they ensure the effectiveness and efficiency of humanitarian response and contribute to unprecedented financial support for Ukraine in the global dimension. Thanks to this, in a fairly short time, a new space for humanitarian action began to form in Ukraine, in which the presence of international and national humanitarian actors was expanded and the interaction of humanitarian actors was improved.

Code-Switching and Accents in Diasporic Multiethnic Literature in Min-Jin Lee’s Free Food for Millionaires and Lisa See’s The Island of Sea Women
Authors:   Center for Asia & Diaspora studies, Moon Set-Byul
Published: March 2023

This article examines the literary representation of codeswitching and various accents between Korean and English in two minority women writers’ fictional territory portraying Korean American characters. Min-Jin Lee’s Free Food for Millionaires and Lisa See’s The Island of Sea Women center around the lives of Korean American women who speak English as a primary language and Korean as a home language or heritage language. The characters’ idea of Korea and “Koreanness” mostly manifests in their identity formation, rather than in their linguistic proficiency or a sense of belonging. Heavily related to the language proficiency and identity of Koreanness, the Korean American protagonists alternate between the languages and accents in linguistic repertoire deeply rooted in sociocultural practices that reflect the concept of diaspora and one’s diasporic identity. Their strategic code-switching signifies how one’s diasporic, immigrant identity affects one’s choice of speech that meticulously synthesizes social values, cultural norms, and ethnic/racial belief systems not only emblematic of mainstream American society but also of a minority community as well.
The Narratives of Mobility in Literary Texts : Three Types of Novels in Korea and Japan
Authors:   Center for Asia & Diaspora studies, Shin Inseop , Kim Jooyoung
Published: March 2023

This paper focuses on how the narrative technique relates to mobility in Korean and Japanese literature. In general, pure, diaspora, and multicultural literature are heavily armed with ideological foundations and premised on being read on their own terms. However, what commonalities and differences in these thematic areas would arise if the motif of mobility supplanted other interpretive modes in the novels? This study analyzes how the mobile subject shaped the characteristics of each era through movement. It aims to refine the reading of modern novels aimed at establishing the modernity of the subject, diaspora novels in the Cold War era, and novels in the 2000s characterized by the theme of multiculturalism. Thus, this paper pointed out that the establishment of modern novels was triggered by movement and then examined how the lives of the diaspora in the Cold War era were narrated from the ethical point of view of mobility. Furthermore, the multicultural situation of globalism further amplified this phenomenon after the Cold War.
Indonesian Nationalism in Three Acts: The Intertwined Narratives of National Identity and the Subaltern Woman in Three Iconic Indonesian Novels
Authors:   Center for Asia & Diaspora studies, Wulandari Elisabeth Arti
Published: March 2023

This article examines the evolution of the intertwined narratives of nation and womanhood in three iconic Indonesian novels: Belenggu (1940), Sri Sumarah (1975), and Durga Umayi (1991), each of which, respectively, depicts female protagonists wrestling with life challenges during three different historical epochs of the Indonesian nation-state. I argue that these novels portray three distinct conceptions of an evolving Indonesian nationalism as reflected through the struggles of these characters. The first of these, Belenggu, highlights the hybrid nature of emerging Indonesian nationalism through the symbolic deployment of hybrid music–keroncong–as a central trope. The second novel, Sri Sumarah, depicts the culturally idealized qualities of a submissive woman–embodied in its titular character–and the gendered nature of nationalism. The third, Durga Umayi, kaleidoscopically maps the biography of its heroine onto the triumphs and defeats of the nation as experienced from the perspective of the subaltern subject, thus depicting the project of nation-building as seen, experienced, and lived from an inferior social position. Taken together these three novels dramatize three different stages of Indonesia as “imagined community”: from the promise and the peril of the early years as an emerging nation-state, to its division along ideological lines before and after the 1965 coup, and ultimately to the failed promises attending the spread of neoliberalism and globalization in subsequent decades.

After 1980 the Increase of Foreign Capital Banks in the Turkish Banking System by Ownership Structure and Its Effects on the Financial Performance of the Sector
Authors: DENİZ Müjgan , HACIOĞLU Aylin
Published: March 2023

In the climate of rapid transformation in the Turkish economy and integration with global economies, new players have emerged in many sectors. For the last decades, the general economic outlook has begun to diversify and become an economy in which not only domestic companies but also foreign capital companies operate. Especially after 1980, policies involving financial liberalization have increased foreign capital inflows into the banking sector of Turkish economy over time. In this context, the ownership status of most of the national private banks has changed by mergers and acquisitions. Also, there is a rapid increase in the number of new foreign banks which were established and started to operate across the sector.
The aim of this study is to search the effects of foreign capital inflow into Turkish banking sector for the last decades. For this reason in the first place, a general information has been given about the economic policies and the change in the financial system in Turkey since 1980. After that, a variety of performance measurements have been examined in this study. Namely, apart from the public banks, state-owned commercial banks, privately-owned commercial banks and the banks owned by foreign capital in Turkey have been taken in to consideration and the selected ratios/indicators of the relevant banks have been compared with the sector averages. The observations and comparisons have been made mainly on a period of last ten years, between 2009-2019. While the reasons that attract multinational companies and foreign capital banks to the Turkish economy and the effects of the increase in the number of foreign capital banks in the sector are discussed, the financial performances of foreign banks are examined by comparing them with the performances of other public and private banks

Published: March 2023

Cupric oxide (CuO)/iridium (Ir) (1/5 wt%) catalysts deposited on carbon nanotubes (CNTs) are considered to be adequate active catalysts for ammonium dinitramide (ADN) decomposition. In this study, the decomposition of ADN ionic liquid was performed over CuO crystallites deposited on Ir CNTs, which were highly distributed due to their high surface area. The catalyst activity was evaluated by calculating the turnover frequency (TOF) of CuO crystallites with different content amounts into the catalyst surface. The highest activity for ADN decomposition was demonstrated over CuO at 1 wt% due to its highest calculated TOF. The TOF was influenced by the presence of ammonium nitrate as an impurity in the ADN solution.

Published: March 2023

To investigate the differences between Korean Ganoderma lucidum spore powder (KP), broken-spo-roderm KP (BSKP), Chinese traditional G. lucidum spore powder (CP), and broken-sporoderm CP (BSCP), they were identified by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), second derivative infrared spectroscopy (SD-IR), dual-index sequence analysis (DISA) and X-ray diffraction (XRD). SEM showed that there were no significant differences in microstructure between the two kinds of spore powders. FT-IR spectra showed that the four spore powders appeared with characteristic peaks of 3400, 3006, 2925, 1745, 1535, 1454, 1249, 1074, 1049, and 896 cm-1, respectively, they were contained the characteristic peaks of total triterpenes, polysaccharides and fatty acids. DISA showed that the same species of spore powders, the overall similarity of before and broken the sporoderm was high with minor differences and there were no differences between the different kinds of spore powders. Similarity analysis showed that the four spore powders were in high agreement and were no differences. The polysaccharide, total triterpene, spore oil and protein content of the four spore powders were determined separately. The results showed that the active ingredients content of the batch of KP were lower than that of CP, that of BSKP were lower than that of BSCP, while the active ingredients content of both broken-sporoderm spore powders were higher than that of before broken-sporoderm. It is inferred that the structure of the main chemical and component of KP is the same as that of CP. This study provides a reference for the future development and application of G. lucidum.

Published: March 2023

Gastric cancer (GC) ranks third for cancer-related fatalities worldwide. It is still unclear what causes GC to progress. Using integrated bioinformatics analysis, COL5A2 has been proved to be related to GC development, which may identify the likely pathogenic mechanism. Data from GC patients were gathered using The Cancer Gene Atlas (TCGA) and the gene expression omnibus (GEO). The level of COL5A2 expression was compared between paired GC and normal tissues. The differentially expressed genes (DEGs) in GC patients with high and low COL5A2 expression were identified using functional enrichment analysis to identify the signature pathways linked to the DEGs. The clinical pathologic traits connected to overall survival (OS) of GC patients were examined utilizing Cox regression and the Kaplan-Meier method. To assess the prognostic significance of COL5A2, receiver operating characteristic (ROC) curves was drawn. How the immune system infiltrate both normal gastric and GC tumor tissues was investigated. Using the human protein atlas (HPA) database, regression, and the Kaplan-Meier method, immunohistochemical analysis of DEG COL5A2 expression in GC tissues was carried out. The correlation between COL5A2 expression and the GC grouping was found to be highly significant. Functional annotations revealed that COL5A2 participates in extracellular matrix structure, collagen metabolism, and other biological processes (BPs). High COL5A2 expression was associated with poor prognostic and clinical features, such as clinical T, N, and M stages. ROC curves exhibited that COL5A2 might predict the occurrence of gastric cancer. The infiltration degree of 21 immune cell subsets, including activated dendritic cells (aDCs), CD8+ T cells, and cytotoxic cells, was found to be dramatically relevant to COL5A2. Immunohistochemical analysis indicated that the expression of COL5A2 in tumor tissues is higher than that in normal tissues. The COL5A2 gene may offer fresh perspectives on the pathogenic mechanism underlying GC, as well as potential biomarkers for estimating GC patient prognosis. As a result, COL5A2 may be a useful biomarker for predicting patient survival.
"BORN INTO THE WRONG FAMILY": NAVIGATING BEING A BLACK MALE IN STEM
Authors: White Angela M. , Morton Terrell R.
Published: March 2023

The underrepresentation of African Americans in science, technology, engineering, and mathematics
(STEM) degree programs and professional spaces has been a national concern for years. This
phenomenon has prompted the development and implementation of various programs and initiatives
to increase access to and sustain their participation in STEM. Of considerable importance, African
American men only represent three percent of the scientists and engineers working in the field. However,
there are few studies that have explored the academic and professional experiences of African
American men through critical, holistic perspectives. This project utilizes critical race theory (CRT)
and phenomenological variant ecological systems theory (PVEST) to magnify the experiences of Black
men in STEM across academic and professional ranks. Through this combined CRT and PVEST lens,
analyzing the challenges and navigational strategies of Black men in STEM, we reveal that Black
men in STEM minimize their vulnerability to stereotypes and biases through resistance and resilience.
Moreover, the utilization of a virtual counterspace as the research context for conversation between the
participants provided a unique interventional approach that fostered rich intergenerational dialogue
that enhanced both navigational and resistance capital for the participants. Implications for research
and praxis are provided.

Sustainable Development (SD) competencies are an important area in engineering education. Engineers play a major role in working and adapting the latest technology sustainably. Undergraduate students who the future individuals are taking the engineering education towards the development of a modern sustainable world must exhibit certain objectives. The implementations of two of the objectives are being highlighted in this paper. The first is to make the students undergo self and sustainable learning through illustrations and activities which results in the enhancement of knowledge there by improvising the competence levels in acquiring skills and knowledge. The second objective is to reduce the burden of stress by integrating learning with real-time human values through the approach of right thinking, peaceful thoughts, and emotional balance. Applying the activity-based assessment through the course called Universal Human Values is considered which further makes the students learning more joyful through presentation sand interactions in a group which results in enhancing communication skills and finally submitting the report. A very important outcome of a student-centric system is a continuous internal evaluation of student performance. Compared with the last two decades, the internal assessment was based only on class tests which resulted in a lack of a teaching-learning process. In this paper, the continuous assessment through activities-based self-learning is presented with the documented results considering the case study. Exploring the social values at the macro-level and paying attention to the overall development of human values. Finally, the analysis shows the transformation of learning from a teacher-centric to a student-centric method. This helps in improving overall academic performance.

Engineering and Technology is a very dynamic sector and change is very rapid. The knowledge gained in traditional classrooms, through online lectures, through search engines, online video books, and Wikipedia is just helping to understand the theoretical concepts. These information sources cannot develop abilities to apply the theoretical concept to real-world problems. This can be developed through experiential learning in workshops, industrial visits, field visits, etc. The advanced courses are not having this scope due to limited lab capacities, high instrument costs, a variety of instruments, quick revisions in technology, less number of industries, IP securities, and many more reasons. The Automobile sector is a vibrant one and the Automobile Engineering department is always facing these issues.

In order to balance the time and course load, the author aims to introduce a demonstration-based teaching approach that will assist students, master the necessary course content and improve their independent problem-solving ability in a very short period of time. This study recommends using demonstration sets of problem-based learning exercises to measure the level of knowledge (apply and analyze). Statistical tools were used to describe the impact of the electrical machine demonstration kit course in the Mechatronics Engineering curriculum and to analyze the internal results. Using these techniques, teachers expect students to have a better understanding of the basics of the machine after learning and experimenting. The questions are answered and the conclusions are verified by the students using simulators based on laboratory experiments. In addition, three different types of electric motors—servo motors, stepper motors, and brushless DC motors are used for the study to demonstrate the proposed learning technique. Three different types of motors are compared via theoretical analysis, modelling, and experimental verification. The majority of students are able to supplement themselves and reach the right conclusions based on an examination of their problem-solving techniques. The suggested strategy can aid students in developing their problemsolving skills. Keywords— Demonstration Kit, Problem solving skills, Creative question-based assessment, Q-NET, Electrical machines

The escalating transits of learners across the international boundaries have resulted into several eruptive pedagogical practices in the class room teaching. A paradigm shift in the pedagogies has been experienced by the teachers to fulfilling the academic demands by the international learners. Though the teaching-learning processes have become more effective, versatile and technology driven due to the learners’ diversity, it may be important to understand the challenges, barriers and psychological reflections by the teachers in facing these transformations. The article analyses the reflections by the teachers on the catering to the student’s diversity. Total of sixty one teachers from different engineering streams participated in the survey. The data were collected anonymously. A metaanalysis has been carried out to obtain the similarities and differences of reflections on various hypotheses. All the important attributes of academics namely pedagogic, assessment, method of instructions, cultural integration of students in a common task, and overall influence of the diversity on the teaching-learning processes have been discussed. The study revealed that the teachers had to accommodate the diversity in their concurrent pedagogic and students had to develop new learning styles. The teachers have shown agreement on most of the hypothesis mentioned in the questionnaire; however it was found that catering the students’ diversity in the class room is the function of the interpersonal skills, academic experience and ability to communicate effectively with the diversified learners. The results established that the teachers will have to accommodate the learner’s diversity by a continuous up gradation and by embracing the new ways of pedagogical practices. The study inspired the authors to propose a model for effective pedagogy in the diversified class rooms and has been presented for the futuristic discussion by the readers and academicians.

This class note helps to develop skills that enable students to generate ideas of digital, social, and solidarity entrepreneurship from identifying social problems. It begins by emphasizing the need to promote digital, social, and supportive entrepreneurship. Then it defines social problems that are articulated with the national legal framework and the sustainable development goals (SDGs). Next, it describes the business idea as an opportunity to solve a social problem, working throughout the process under the Design Thinking methodology. This technique is focused on creativity and is used strongly for problem-solving, business modeling, strategic planning, and idea development, allowing for innovation in many aspects focused on the user. This approach helps to identify what people need and want, as well as what they like or dislike. Finally, the learning unit’s product is explained, which must be a technical sheet that reflects the use of the Design Thinking methodology as a strategy for obtaining business ideas. Through these contents, students develop the competence to analyze social problems, generate ideas of digital, social, and solidarity entrepreneurship that are aligned with existing policies and the SDGs.

The COVID-19 pandemic may have been psychologically stressful for everyone who was affected by it, but people who are predisposed to mental health problems may have felt it more intensely than others. Students at universities are one of these vulnerable populations. The uncertainty brought on by COVID-19 had a negative psychological impact on them, but this effect became more complex in the process of restarting education after a long break. The purpose of this study is to investigate the psychological situation of Turkish university students during the period when face-to-face education began to reappear as a result of the COVID-19 precautions being reduced. For this aim, the psychological situation of 224 Turkish students aged 17–25 was assessed using the Beck Depression Inventory (BDI), State and Trait Anxiety Scale (STAT), Connor Davidson-Resilience Scale (CD-RISC), Positive and Negative Affect Schedule (PANAS), and Brief Symptom Inventory (BSI). In addition, the students were asked about their life satisfaction, chronic illness, duration of physical activity, screen time, and needs of psychological support. The results revealed that during this period, students reported low levels of exercise and physical activity time, increased time spent in front of a screen, low life satisfaction, higher rates of receiving and needing psychological support, and higher levels of negative affect, depression, anxiety, and brief symptoms. Furthermore, the results showed that positive affect and resilience are protective factors for psychological health. The findings of the study highlighted the critical role of psychological support services at universities in promoting and preserving students' mental health.

Cucurbitaceae species constitute a family with a wide worldwide distribution and great nutritional and medicinal importance. The Cucurbita genus is the most important of the family with valuable species such as C. maxima and C. moschata. However, the large-scale production of sex specific plants using the conventional propagation methods has various limitations. The tissue culture such as micropropagation can help overcome these limitations. The aim of this study was to establish a protocol for ex vitro and in vitro clonal propagation of two varieties of Cucurbita moschata: ‘loche’, a variety of commercial vegetative propagation and endemic in Lambayeque, and ‘chuyán’ another variety of very restricted cultivation in some Andean regions of the north of the Peru. Likewise, the in vitro propagation of ‘chisguín’ (C. ecuadorensis), a threatened endemic wild species from the coast of Ecuador. ‘Loche’ was propagated ex vitro by microcutting with a node and leaf, and micropropagated in MS culture medium supplemented with 0.02 mg L-1 IAA and 0.02 mg L-1 GA3. Seedlings of ‘chuyán’ and ‘chisguin’ were micropropagated in MS with with 0.02 mg L-1 IAA, 0.5 mg L-1 BAP and 0.02 mg L-1 GA3. This study constitutes the first report on micropropagation of Peruvian and Ecuadorian varieties and species of the Cucurbita genus.
