Published: June 2023

Four compounds (1, 5, 7, and 8) were first isolated from the genus Belamcanda Adans. nom. conserv., and six known compounds (2–4, 6, 9, and 10) were isolated from the rhizome of Belamcanda chinensis (L.) DC. Their structures were confirmed by spectroscopic data. Herein, compounds 1–10 were rhapontigenin, trans-resveratrol, 5,7,4′-trihydroxy-6,3′,5′-trimethoxy-isoflavone, irisflorentin, 6-hydroxybiochannin A, iridin S, pinoresinol, 31-norsysloartanol, isoiridogermanal, and iristectorene B, respectively. All compounds were evaluated for their antiproliferative effects against five tumor cell lines (BT549, 4T1, MCF7, MDA-MB-231, and MDA-MB-468). Among them, compound 9 (an iridal-type triterpenoid) showed the highest activity against 4T1 and MDA-MB-468 cells. Further studies displayed that compound 9 inhibited cell metastasis, induced cells cycle arrest in the G1 phase, exhibited significant mitochondrial damage in 4T1 and MDA-MB-468 cells including excess reactive oxygen species, decreased mitochondrial membrane potential, and induced 4T1 and MDA-MB-468 cell apoptosis for the first time. In summary, these findings demonstrate that compound 9 exerts promising potential for triple-negative breast cancer treatment and deserves further evaluation.

Published: June 2023

Vitamin K and vitamin K-dependent proteins have been reported to be associated with a large spectrum of age-related diseases. While most of these associations have been deduced from observational studies, solid evidence for the direct impact of vitamin K on cellular senescence remains to be proven. As vitamin K status reflects the complexity of interactions between dietary intake, gut microbiome activity and health, we will demonstrate the pivotal role of the diet-microbiome-health axis in human ageing and exemplify how vitamin K is implicated therein. We propose that food quality (i.e., food pattern) should be highlighted beyond the quantity of total vitamin K intake. Instead of focusing on a single nutrient, exploring a healthy diet containing vitamin K may be more strategic. As such, healthy eating patterns can be used to make dietary recommendations for the public. Emerging evidence suggests that dietary vitamin K is a modulator of the diet-microbiome-health axis, and this needs to be incorporated into the investigation of the impact of vitamin K on gut microbial composition and metabolic activities, along with host health outcomes. In addition, we highlight several critical caveats that need to be acknowledged regarding the interplay between diet, vitamin K, gut microbiome and host health that is pivotal for elucidating the role of vitamin K in ageing and responding to the urgent call of healthy eating concerning public health.
Elevated Intraocular Pressure and Glaucomatous Optic Neuropathy: Genes to Disease Mechanisms, Therapeutic Drugs, and Gene Therapies
Authors: Sharif Najam A.
Published: June 2023

This review article focuses on the pathogenesis of and genetic defects linked with chronic ocular hypertension (cOHT) and glaucoma. The latter ocular disease constitutes a group of ocular degenerative diseases whose hallmark features are damage to the optic nerve, apoptotic demise of retinal ganglion cells, disturbances within the brain regions involved in visual perception and considerable visual impairment that can lead to blindness. Even though a number of pharmaceuticals, surgical and device-based treatments already exist addressing cOHT associated with the most prevalent of the glaucoma types, primary open-angle glaucoma (POAG), they can be improved upon in terms of superior efficacy with reduced side-effects and with longer duration of activity. The linkage of disease pathology to certain genes via genome-wide associated studies are illuminating new approaches to finding novel treatment options for the aforementioned ocular disorders. Gene replacement, gene editing via CRISPR-Cas9, and the use of optogenetic technologies may replace traditional drug-based therapies and/or they may augment existing therapeutics for the treatment of cOHT and POAG in the future.
Experimental Verification of the Possibility of Reducing Photoplethysmography Measurement Time for Stress Index Calculation
Authors: Lee Seung-Gun , Song Young Do , Lee Eui Chul
Published: June 2023

Stress is a direct or indirect cause of reduced work efficiency in daily life. It can damage physical and mental health, leading to cardiovascular disease and depression. With increased interest and awareness of the risks of stress in modern society, there is a growing demand for quick assessment and monitoring of stress levels. Traditional ultra-short-term stress measurement classifies stress situations using heart rate variability (HRV) or pulse rate variability (PRV) information extracted from electrocardiogram (ECG) or photoplethysmography (PPG) signals. However, it requires more than one minute, making it difficult to monitor stress status in real-time and accurately predict stress levels. In this paper, stress indices were predicted using PRV indices acquired at different lengths of time (60 s, 50 s, 40 s, 30 s, 20 s, 10 s, and 5 s) for the purpose of real-time stress monitoring. Stress was predicted with Extra Tree Regressor, Random Forest Regressor, and Gradient Boost Regressor models using a valid PRV index for each data acquisition time. The predicted stress index was evaluated using an R2 score between the predicted stress index and the actual stress index calculated from one minute of the PPG signal. The average R2 score of the three models by the data acquisition time was 0.2194 at 5 s, 0.7600 at 10 s, 0.8846 at 20 s, 0.9263 at 30 s, 0.9501 at 40 s, 0.9733 at 50 s, and 0.9909 at 60 s. Thus, when stress was predicted using PPG data acquired for 10 s or more, the R2 score was confirmed to be over 0.7.
Survey on the Acceptance of Ambient Sensors in Solo and Older Couple-Only Households in Japan
Authors: Igarashi Toshiharu , Nihei Misato
Published: June 2023

For this study, an online survey was conducted to discover the preferences of older adults when they used sensors in their households, rather than the preferences of the researchers who developed them. The sample size was 400 Japanese community-dwelling people aged 65 years and older. The numbers of samples for men and women, household composition (single-person/couple-only household), and younger senior (younger than 74 years old) and older senior (older than 75 years old) were equally assigned. The survey results showed that “informational security” and “constancy of life” were considered more important than other factors when installing sensors. Furthermore, looking at the results regarding the type of sensors that face resistance, we found that both cameras and microphones were evaluated as facing slightly strong resistance, while doors/windows, temperature/humidity, CO2/gas/smoke, and water flow were evaluated as not facing such strong resistance. The elderly who are likely to need sensors in the future also have various attributes, and the introduction of ambient sensors in elderly households may be further advanced by recommending applications that are easy to introduce based on the attributes of the target population, rather than discussing all of them in general.

Authors: Cheng Hanquan , Xiong Jiping , Chen Zehui , Chen Jingwei
Published: June 2023

In this paper, a multi-stage deep learning blood pressure prediction model based on imaging photoplethysmography (IPPG) signals is proposed to achieve accurate and convenient monitoring of human blood pressure. A camera-based non-contact human IPPG signal acquisition system is designed. The system can perform experimental acquisition under ambient light, effectively reducing the cost of non-contact pulse wave signal acquisition while simplifying the operation process. The first open-source dataset IPPG-BP for IPPG signal and blood pressure data is constructed by this system, and a multi-stage blood pressure estimation model combining a convolutional neural network and bidirectional gated recurrent neural network is designed. The results of the model conform to both BHS and AAMI international standards. Compared with other blood pressure estimation methods, the multi-stage model automatically extracts features through a deep learning network and combines different morphological features of diastolic and systolic waveforms, which reduces the workload while improving accuracy.
Surface Properties of Global Land Surface Microwave Emissivity Derived from FY-3D/MWRI Measurements
Authors: Xu Ronghan , Pan Zharong , Han Yang , Zheng Wei , Wu Shengli
Published: June 2023

Land surface microwave emissivity is crucial to the accurate retrieval of surface and atmospheric parameters and the assimilation of microwave data into numerical models over land. The microwave radiation imager (MWRI) sensors aboard on Chinese FengYun-3 (FY-3) series satellites provide valuable measurements for the derivation of global microwave physical parameters. In this study, an approximated microwave radiation transfer equation was used to estimate land surface emissivity from MWRI by using brightness temperature observations along with corresponding land and atmospheric properties obtained from ERA-Interim reanalysis data. Surface microwave emissivity at the 10.65, 18.7, 23.8, 36.5, and 89 GHz vertical and horizontal polarizations was derived. Then, the global spatial distribution and spectrum characteristics of emissivity over different land cover types were investigated. The seasonal variations of emissivity for different surface properties were presented. Furthermore, the error source was also discussed in our emissivity derivation. The results showed that the estimated emissivity was able to capture the major large-scale features and contains a wealth of information regarding soil moisture and vegetation density. The emissivity increased with the increase in frequency. The smaller surface roughness and increased scattering effect may result in low emissivity. Desert regions showed high emissivity microwave polarization difference index (MPDI) values, which suggested the high contrast between vertical and horizontal microwave signals in this region. The emissivity of the deciduous needleleaf forest in summer was almost the greatest among different land cover types. There was a sharp decrease in the emissivity at 89 GHz in the winter, possibly due to the influence of deciduous leaves and snowfall. The land surface temperature, the radio-frequency interference, and the high-frequency channel under cloudy conditions may be the main error sources in this retrieval. This work showed the potential capabilities of providing continuous and comprehensive global surface microwave emissivity from FY-3 series satellites for a better understanding of its spatiotemporal variability and underlying processes.
Intelligent RBF-Fuzzy Controller Based Non-Isolated DC-DC Multi-Port Converter for Renewable Energy Applications

Published: June 2023

In this article, a multi-port non-isolated converter is implemented for renewable energy applications. High voltage gain is accomplished with a switched capacitor and coupled inductor, and power transfer between the inputs, battery, and load can be realized using three power switches. The power collected in the leakage inductance is reused to decrease the voltage stress on the power switch. Various functioning periods are also examined, and design requirements are offered. The proposed converter uses fewer parts to realize power flows and obtain high voltage gain compared to comparable converters. Additionally, under partial shading conditions, the traditional maximum power point tracking (MPPT) approaches are not able to collect the global maximum power point (MPP) from the numerous local MPPs. This work proposes an artificial neural-network-based MPPT technique with variable step size for tracing speed, MPP oscillations, and operating efficiency. The proposed converter experiment is also constructed and successfully tested in a laboratory environment.
Incandescent molecules: An analytical investigation into materiality in contemporary abstract painting
Authors:   , Cook Linda
Published: June 2023

This project began by considering abstract painting across the twentieth century, from Malevich to Nozkowski, and subsequently looked at contemporary New Zealand practice. This analysis secured my work within the genres of neo-casualism and new materiality. New materiality accepts that all matter, whether substance or object, has agency and presence. Materials are full of surprises; I celebrate the messy vitality of uncontrollable materials and rejoice at the random slippage of an edge. Quirky, off kilter, seemingly unrefined forms, are characteristic of neo-casualism. Humour is combined with an anti-heroic style. All these elements have been central to my practice. A curious and unexpected body of work has emerged from blending new materiality and neo-casualism, and synchronising discordant elements with waste materials. In working with raw, unpredictable materials and embracing the random ooze or slip, each painting has developed its own personality. The surface and the edge rise to the fore in this body of work. I use the value and vitality of the edge to enliven the centre of the picture plane. The expansive picture plane begins as a sheet of cardboard. By combining textural surface with carefully chosen colours, the cardboard sheds its humble beginning to become an art object. This is no mean feat. The surface eventuates from layers of sealants, gesso, and paint to which texture is added –straw, hair, paper, whatever is at hand. Onto this, layers of colour and clayare pasted and secured as the paintings are built up. These constructions begin to register as objects which have moved beyond representation and into the realm of real form. This praxis has opened broader discussions for my practice, opening avenues for continued rumination on materiality, rhythms and making. Keywords: abstract art, painting, materialism, neo-casualism, philosophy of art, painting practices, New Zealand

Published: June 2023

In this study, we compare interlaced and multiscale sampling of smooth manifolds for snapshot compressive imaging. With a particular focus on spectral, spatial, and temporal focal photographic imaging systems, we show that structured transformer networks enable the efficient integration of multiscale manifolds. In the applications considered here, transformer networks enable simpler and more target-specific sampling strategies for compressive tomography.

Decoding of spatial proportions using somatosensory feedback in sighted and visually impaired children
Authors: Leukel Christian , Leuders Timo , Leuders Juliane
Published: June 2023

Background and purposeHumans can naturally operate with ratios of continuous magnitudes (proportions). We asked if sighted children (S) and visually impaired children (VI) can discriminate proportions via somatosensory feedback.ProceduresChildren formed a proportion by tracing a pair of straight lines with their finger, and compared this proportion with a second proportion resulting from the tracing of another pair of lines.Main findingsPerformance was 68% in S, thus significantly lower (p < 0.001) compared to VI (75%). Tracing velocity (p < 0.01) and trial-to-trial variability of tracing velocity (p < 0.05) was higher in S compared to VI.ConclusionsOperating with proportions solely from somatosensory feedback is possible, thus tracing lines might support learning in mathematics education. Kinematic variables point to the reason for the difference between S and VI, in that higher trial-to-trial variability in velocity in S leads to biased estimation of absolute line lengths.

Published: June 2023

It is a significant issue in controlling the polarization distribution in ferroelectric nematic liquid crystal cells. We investigated the polarization configuration of ferroelectric nematic liquid crystals on the surface and in the bulk of parallel/anti-parallel cells with rubbed substrates and proposed the polarization models in each cell. It is found that on the surface of rubbed polyimide films, the polarization direction is fixed and opposite to the rubbing direction. Splay and twist distribution of the polarization are formed in parallel and anti-parallel cells, respectively.

Published: June 2023

Постановка задачи. На фоне отмены русской культуры в европейских странах мы считаем, что российским студентам необходимо развивать общекультурную и иноязычную коммуникативную компетенции на лучших образцах мировой культуры. Британская литература XX века напрямую связана с событиями жизни предшествующего времени и представлена творчеством таких писателей, как Дж. Голсуорси, А. Конан-Дойль, Р. Киплинг, У. Моэм, О. Уайльд, Г. Уэллс, Б. Шоу и др. Британская литература XX века — это реалистические и модернистские произведения, фэнтези, детективы и научная фантастика, представляет «золотой век» ее расцвета и отражает перемены, происходящие в обществе, поиск вечных истин и защиту традиционных для всех ценностей. Целью исследования является формирование иноязычной читательской компетенции студентов - будущих учителей иностранного языка 1 и 2 курсов с использованием произведений Британской литературы ХХ века. Результаты. Воздействие содержательной формы литературы на мировоззрение, взгляды, ценности студентов происходит на осознанном и неосознанном уровнях. Чтение представляет собой сложный мыслительный процесс, который осуществляется посредством косвенного управления через отбор текста и методическое сопровождение со стороны педагога по усвоению его содержания. Анализ результатов констатирующего этапа выявил недостаточный уровень знаний британской литературы XX века в экспериментальной и контрольной группах у студентов – будущих учителей иностранного языка. В связи с этим была разработана экспериментальная программа, направленная на оптимизацию процесса обучения английскому языку и повышение уровня знаний британской литературы XX века у студентов, что обусловило проведение формирующего этапа эксперимента. Выводы. В целом мы пришли к выводу, что работа с содержательной формой британской литературе XX века представляет особую культуру взаимоотношений со студентами, способствует формированию ценностных установок, самостоятельности, высокой мотивации к познавательной деятельности. Важно предусмотреть усвоение британской литературы XX века на основе анализа биографии писателя, основ литературной критики, влияние сюжетов и авторской идеи на жизнь человека.

Degree and nature of heterosis effects in corn lines by grain quality parameters
Authors: Spriazhka R.O. , Zhemoida V.L.
Published: June 2023

Aim. Widespread use of corn hybrids, which are of key importance for the food security in Ukraine, is one of the most successful examples of the heterosis phenomenon use. In order to recommend new and high-quality corn hybrids for production, it is necessary to assess the inheritance degree and heterosis effects for protein, starch and oil contents as well as for yield.
Results and Discussion. To achieve the goal, we used the classic field techniques and methods of qualification examination of plant varieties for suitability for distribution in Ukraine. The protein, starch and oil contents in grain were determined on a InfratecTM 1241 Grain Analyzer (FOSS); the heterosis effects were calculated by D. S. Omarov’s methods. As a result of tester crosses, 65 experimental corn hybrids were obtained. Inbred lines VK13, VK69, AE801 and AE392 (carriers of the wx and ae mutations of endosperm structure, respectively) were the female forms. Inbred lines СО255, АК159, АК157, G255, FV243 and KhLG1203 were used as male components for the first time to obtain hybrids with high grain quality parameters. From the 2020−2021 studies, we found that, in terms of grain quality, the grain starch content-driven selection of parental pairs was the most rational approach, as the influence of parental forms on this trait consistently exceeded 50% across the study years.
Conclusion. Hybrids VK13×UKhK678 and VK13×UKhK686 were noticeable for consistently high manifestation the heterosis effects for several parameters. As to the starch content in grain, superdominance of a parental form with stronger expression of the trait was recorded in hybrids VK13×UKhK678, VK13×UKhK686, VK19×FV243, and AE801×VK32; as to the oil content in grain, VК13×UKhК678, VК13×UKhК686, VК13×VК37, АЕ392×СО255, АЕ392×KhLG1203, and АЕ392×АК157 were distinguished. Inbred corn lines that should be used as parents of heterotic corn hybrids (KhLG1203, CO255, AK159 and AK157) were singled out.

Published: June 2023

Aim. To identify collection accessions – sources of valuable traits for using as starting material to create varieties of perennial grasses in Western Ukraine.
Results and Discussion. The vegetable protein problem is one of the main issues facing scientists whose activities are related to agriculture, ecology and other areas of biology. The Ciscarpathia is a zone of natural meadows, hayfields and pastures, where a large number of plant species belonging to different botanical families grow. Among the natural vegetation on pastures, meadows and fallows, clover species are most often found. Trifolium incarnatum L. is an annual winter-spring plant. It is widely used in agriculture as a nitrogen-fixing cover crop. The crimson clover collection comprises 24 accessions. Some promising accessions that can be used as starting material in breeding for high productivity (green mass, hay and seeds), herbage capacity, resistance to diseases and pests were selected. Reference accessions and sources of economically valuable traits, which are actively involved in breeding, were singled out. During the study (2019-2021), accessions were investigated in detail for biological and morphological features. We evaluated the crimson clover collection for germinability, winter survival, flowering time, green mass per plant, and seed yield. The results showed that the crimson clover collection could be tentatively divided into 3 groups: early-ripening (70-79 days; 37.5%), mid-ripening (83-87 days; 50.0%) and late-ripening (92-94 days; 12.5%). Nine accessions (PFZ 00625, PFZ 02148, PFZ 01264, PFZ 01266, PFZ 01295, PFZ 01273, PFZ 01270, PFZ 02266, and PFZ 02265) ripened slightly earlier. They are potential parents to develop an early-ripening population. Three accessions (PFZ 02268, PFZ 02267, and PFZ 02073) ripened significantly later than all the others. Thus, these accessions are excellent candidates to develop a late-ripening population. Depending on the region and cultivation system, farmers may be interested in both early-ripening and late-ripening crimson clover.
Conclusions. Literature review allowed us to note that the studied crimson clover accessions had several advantages when used in production, namely: they are annuals, have high vegetation rates and productive potentials. Crimson clover accessions showed particularly distinct differences in autumn emergence and flowering time, indicating greater diversity and potential for breeding. In contrast, winter survival, green mass per plant showed greater intra- and inter-year variations. Autumn emergence and winter survival were found to be positively correlated, and both traits were negatively correlated with green mass per plant. Some accessions were identified as highly effective in several key traits and are of particular interest as parents in further breeding: PFZ 02118, PFZ 01270, PFZ 02267, PFZ 02073, PFZ 02072, PFZ 01290.

Environmental sustainability of national economic systems in modern conditions
Authors: PAVLENKO Olena , HOU Bo
Published: June 2023

Introduction. In current conditions, the most urgent research question for every national economic system is strengthening environmental sustainability. Accordingly, as experience shows, in the conditions of Russia's war against Ukraine, the situation with the formation of ecological sustainability of those territories where fierce fighting takes place was most acutely affected. The world community is concerned about the case at the Zaporizhzhia nuclear power plant and international organizations' constant shelling and lack of control. Despite the impact of the war on the ecological stability of national economic systems, several problems that also significantly affect it remain unresolved. That is why studying the environmental sustainability of the national financial system under current conditions is quite relevant.
The purpose of the article is to research the environmental sustainability of the national economic system under current conditions.
The results. The conducted studies showed that among the main areas of increasing environmental sustainability are: the implementation of norms of international humanitarian law on the territory of Ukraine in terms of ecological safety, the creation of regional low-waste systems, use of substances and energy that have already been used; use of innovative equipment and technologies that will reduce the amount of pollution; organization of ecological and organic production; use of energy efficiency and energy saving tools.
Conclusions. It is substantiated that to strengthen the ecological sustainability of national economic systems, strategic priorities have been determined that must be implemented in relevant strategies at all levels of public administration, in particular in the field of rational use of water resources; improvement of atmospheric air condition; increasing energy efficiency is important to continue the gradual thermal modernization of the housing stock and objects of administrative and social infrastructure; intensification of cooperation between condominiums and management bodies of OTC in the direction of creating funds and transparent use of funds for the implementation of thermal modernization projects; reconstruction and construction of new boiler houses and other heat and power systems in the direction of transition to the use of alternative energy sources; waste management. The importance of the development of effective institutional, administrative, financial, and organizational mechanisms aimed at the formation of synergistic models of strengthening the ecological sustainability of national economic systems in accordance with the conditions of operation was emphasized.

Published: June 2023

Introduction. Digital transformation is taking place gradually and in stages in Ukraine. However, the coronavirus pandemic and the full-scale war between Russia and Ukraine strengthened digital transformation processes in society in almost all types of activities. It should be noted that Ukrainians are quickly mastering new digital technologies, which accelerates digital transformation. That is why constant research and analysis of modern trends and prospects of digital transformation in Ukraine in current conditions is quite relevant.
The purpose of the article is the research process of modern trends and vectors of digital transformation in Ukraine.
The results. It has been studied that Ukraine has significantly increased its ranking in Open Data in Europe over the past two years. It was noted that in 2021, Ukraine received the maximum value of 220 points for open data management, 160 points for portal use, and 134 points for portal stability. The analysis of modern trends in digital transformation showed insignificant changes in enterprises' digital transformation indicators in 2020, in some cases even smaller than the indicators of 2018. In general, for the years 2018-2020, there were positive changes regarding the increase in the number of enterprises that allowed e-commerce, the share of enterprises that conducted "big data" analysis, completed training in the field of ICT, used 3D printing, and found/attempted to see specialists in the field of ICT. On the other hand, a negative trend of decreasing indicators of the share of all enterprises that sent invoices and the number of enterprises that had vacancies for ICT specialists that were difficult to fill was determined.
Conclusions. It is substantiated that in the conditions of global challenges and military aggression, digital transformation is most effective in three main areas, namely: scale, scope, and speed; property, assets, and economic value; relationships, markets, and ecosystems. Furthermore, it is emphasized that the number of vectors of digital transformation in Ukraine in the conditions of war and globalization challenges are: innovation management, self-service, digital business, shared services 4.0, economic regulation, thinking design, automation of business processes, modeling, knowledge base, innovation ecosystem, digital chain сost, future software, etc.

Essence and evolution of the concept «economic security of the enterprise»
Authors: Zahorodnia Alona
Published: June 2023

This article examines the evolutionary development of the concepts of “security”, “economic security” as components of the concept “economic security of the enterprise”. The types of internal and external threats to the enterprise are analyzed. It has been proven that the most effective use of all types of resources in order to prevent (neutralize, eliminate) threats ensures the stable functioning of the enterprise in the conditions of a market economy. The evolution and definition of the concept are considered, the components of economic security, risks and main goals of economic security of enterprises are derived. It was determined that the concept “economic security” allows to understand that modern enterprises, being in various situations, are forced to make risky decisions to prevent threats and dangers. The concept “economic security of the enterprise” is characterized. It was determined that the economic security of the enterprise is an extremely deep concept. In the most general form, it can be characterized as the absence of various dangers and threats, which, obviously, is hardly possible in the world. The concept of economic security of the enterprise is summarized and a more precise definition is given, which indicates that the economic security of the enterprise is a system that provides the possibility of preventing various threats and as a result of neutralizing these threats, it protects the economic interests of the enterprise and prevents losses above the critical limit. It was proved that the correct management of economic security at the enterprise allows to show that this enterprise, being in a situation of uncertainty, unpredictability, changes in both internal business conditions and external (political, macroeconomic, ecological, legal, etc.), makes risky decisions in the conditions of fierce competition, strives to prevent, weaken or protect against existing or projected dangers and threats, which ensures the achievement of business goals. At the same time, the company’s resources (land, capital, personnel potential, entrepreneurial abilities of managers, information, intellectual property, technology, etc.) are used not only to prevent dangers and threats, but primarily to achieve the main goals of the business.
Keywords: security, economic security, economic security of the enterprise, threats, risks.

Communication and Social Interaction across Cultures: The Case of a German and Ghanaian Educational Exchange Program
Authors: Alhassan Abdul-Razak Kuyini , Abdulai Muhammed , Ibrahim Hadi
Published: June 2023

Using a constructivist epistemology, this paper explores the cross-cultural learning experiences of exchange students from Hochschule Düsseldorf University of Applied Sciences in Germany and the University for Development Studies in Ghana. The findings reveal differences in the students’ commitment to agreements, tasks and time; while the German students have a high commitment to time awareness -- reporting to lectures and other meetings on time -- their Ghanaian counterparts do not. We suggest that universities preparing students for educational exchange programs should actively embark on cross-cultural education and training, providing adequate information on the context and culture of the host country, targeting all stakeholders before, during and after the exchange program. This will enhance effective intercultural relations and social interaction, and minimize culture shock.
