Business Model Innovation for Mobile Application Development for SMEs in Response to Disruptive Innovation
Authors: Francke Errol
Published: December 2023

The central proposition of this chapter is that a multi-factorial strategy
model can be evolved to support mobile application development for SMEs in response
to disruptive innovation through business model innovation. Artificial Intelligence is
often regarded as a significantly disruptive technology impacting many industries
today. AI is penetrating many sectors and transforming the tasks performed by
computers. This chapter rests on two principles: the discovery of business model
innovation and the type of disruption of SMEs in the mobile application sector. The
fieldwork for this chapter consists of four phases. The findings and interpretations
presented in this chapter imply that the rise of disruptive innovation has sparked
technological advancement, which will affect SMEs in South Africa. SMEs should
transition to a progressive interdependent modality where they participate using their
shared strengths, according to the concept of business model innovation. They could
mitigate their weaknesses by working with other mobile app development SMEs. The
value of the principles' synergistic relationship has finally been revealed in the chapter.
The Disruptive Innovation State Response Model and the Disruptive Innovation Praxis
Model were created by this research as responses to its main thesis. A development
agency, businessperson, technologist, venture capitalist, etc. could use these models to
determine the state that the business recognizes itself in and, employing its use,
generate a response that is suitable according to the chapter's final proposition.
Cybersecurity Culture as a Critical Component of Digital Transformation and Business Model Innovation in SMEs
Authors: Mitrovic Zoran , Thakur Colin , Palhad Sudhika
Published: December 2023

Small and medium enterprises (SMEs) are crucial to national and regional development and are significant drivers of job creation and income generation. To remain competitive, SMEs are increasingly adopting Digital Transformation (DT) and Business Model Innovation (BMI) to take advantage of modern digital technologies. However, these transformations can also pose serious cybersecurity risks if organisations do not prioritise cybersecurity threats associated with these modern technologies. Therefore, this conceptual desktop study examines the cybersecurity risks of information and communication technologies (ICT) utilised in DT and BMI processes and recommends fostering an appropriate cybersecurity culture to protect SMEs during and after these transformations.
Assessing SMEs’ Business Model Innovation Readiness
Authors: Kgoetiane Cecil
Published: December 2023

This chapter assesses business model innovation readiness for South African
SMEs. The assessment is based on the perspective of two challenges that SMEs went
through pre-, during, and post-novel coronavirus disease of 2019 (COVID-19). The
challenges are about the readiness to innovate the SMEs’ business models and grip
disruptive technologies such as Intelligent Analytics (IA). To investigate the challenges
identified, the chapter expands on IA. In considering IA, four major areas of IA are
synthesized. Importantly, IA is about smarter ways of doing business across different
sectors. Society 5.0 and the fourth industrial revolution plus (4IR+) complement IA, as
the chapter proposes. By and large, the novel COVID-19 accelerated the adoption of
disruptive technologies. The chapter concludes by considering the role of the SMEs’
owner-managers in embracing the technology.
Understanding the Affordances of Expert Systems in Improving the Competitiveness of South African Insurance SMEs
Authors: Mamorobela Stevens P.
Published: December 2023

Small and Medium Enterprises in the insurance industry of South Africa are
increasingly seeking new ways to improve competitiveness. Recently, technologies like
expert systems are evolving to provide new knowledge to enable organizations to
deliver insurance services more effectively and efficiently. However, little information
is presented in the studies of business model innovation about the affordances of expert
systems in improving the competitiveness of the Small and Medium Enterprises in the
insurance industry. Based on the literature review of the Resource-based view model,
this chapter develops a model of the affordances of expert systems to guide Small and
Medium Enterprises in the insurance industry in their effort to improve
competitiveness. An explanatory mixed-method research approach was followed to
collect relevant data using a questionnaire and semi-structured interviews to understand
the affordances of expert systems in Small and Medium Enterprises in the insurance
industry. The results of the study indicate that competitiveness can be improved if the
Small and Medium Enterprises manage the expert system in five areas: (i) as a valuable
resource; (ii) as a rare resource; (iii) as an inimitable resource; (iv) as a unique
organizational resource; and (v) as a low-cost resource. Since the concept of business
model innovation is centered on resources that generate value, this study has
implications for theory and practice in the field of business model innovation,
particularly in the Small and Medium Enterprises operating in the insurance industry.
Factors Affecting the Adoption of Data as a Service (DaaS) in Small, Medium, and Micro Enterprises (SMMEs)
Authors: Morta Megan , Jokonya Osden
Published: December 2023

Although there are several benefits to the adoption of emerging technologies
by Small, Medium, and Micro Enterprises (SMMEs), not many studies have been
performed on inhibiting Data as a Service (DaaS) (adoption in SMMEs). This study,
therefore, explores Data as a Service (DaaS) adoption factors in Small, Medium, and
Micro Enterprises (SMMEs). The study adopted a systematic literature review and
TOE framework as a lens to explore the possible factors. The study results suggest that
within the technological context, the complexity, network bandwidth, and availability
were considered the most important factors that affected the adoption of DaaS in
SMMEs. Furthermore, within the organizational context, cost, support, and
infrastructure demand were considered the highest factors affecting DaaS adoption in
SMMEs. Lastly, within the environmental context, the results indicate that customer
demand was considered an environmental factor. In conclusion, the study results
suggest that the adoption of DaaS in SMMEs is affected by several TOE factors.
Despite limitations associated with convenient sampling and non-empirical data, the
study contributes to the body of knowledge on DaaS adoption factors by SMMEs.
Further studies may address the mentioned shortcomings by using empirical data.
Factors Affecting the Adoption of Emerging Technologies to Reduce Food Waste by SMEs in the Food Industry
Authors: Muzondo Talent , Jokonya Osden
Published: December 2023

Consumers have now been able to purchase whatever food they wish in the
21st century. Not all the food that is purchased is consumed, resulting in food waste.
About a third of the food produced is wasted in the world. Humans are the main
culprits of food waste. The problem is worsening by each day, with different attempts
failing to counter the problem. The study investigates factors affecting the adoption of
emerging technologies to reduce food waste by SMEs in the food industry. The TOE
framework was used for this purpose. The study adopted a systematic literature review
to explore the factors affecting the adoption of emerging technologies to reduce food
waste by SMEs in the food industry. The results from the study suggest that
complexity, security, usability, cost, and flexibility are important technological factors
that affect the adoption of emerging technologies. Furthermore, the results from the
study suggest that organisation size and organisation resistance are important
organisational factors affecting the adoption of emerging technologies to reduce food
waste by SMEs in the food industry. Lastly, the results from the study suggest that IT
policy and legislation are important environmental factors affecting this technology
adoption. Further studies may consider adopting other research methods to explore
factors affecting adopting emerging technologies in reducing food waste by SMEs in
the food industry.
Pergeseran Pemosisian Subjek Kelas Bawah dalam Tiga Film Bong Joon-Ho
Authors: Pinem Agnes Rosalina
Published: December 2023

Bong Joon-ho is a South Korean film director and the last three film he directed were Snowpiercer, Okja and Parasite. Those films had the same theme which is social class inequality in the capitalist system. Researcher used Norman Fairclough's critical discourse analysis to find out the representation of the lower class in the three films and then used Michel Foucault's subject position theory to find the shifting position of lower- class subjects in three Bong Joon-Ho films. The result, this study found out that there were 4 shifts in the positioning of lower class subjects represented in those three films. In these films, capitalists are portrayed as the winning party but the way Bong Joon-ho positions the relationship between the lower class and the upper class was different. In these films, Bong Joon-ho conveys his thoughts and concern about the impact of the capitalist system to the society. Through his last film Parasite, Bong Joon-ho wanted to show that both the lower class and the upper class could become a victim in the capitalist system. These three films show that there is no alternative to the capitalist system and that in the end people just have to respect each another.

Four-dimensional CT excretory urography imaging findings, cystoscopy and exploratory surgery for the diagnosis of a vesicovaginal fistula in a young dog
Authors: Gracz M. , Saunders J.H. , Devriendt N. , Stock E.
Published: December 2023

An eight-month-old, entire female German Shepherd was referred for investigation of continuous urinary incontinence not responding to medical therapy. A four-dimensional excretory urography (4D-CTEU) abdominal CT scan revealed a hypoattenuating fluid-filled structure dorsally to the urinary bladder, extending cranially, continuing as the uterine horns, and ending blindly caudally. On post-contrast images, during all contrast phases, a continuity of the urinary bladder and cranial vaginal walls was underlined by a hyperattenuating mucosal surface with the creation of a hypoattenuating fistulous tract. Cystoscopy and exploratory surgery confirmed the presence of a vesicovaginal fistula and revealed that the distal vagina and urethra consisted of one structure.
Identity, racial cognizance, and intercultural competence: Students’ collective identities in the virtual literary classroom
Authors: Van Blommestein Sharmain , Bellot Andrea Roxana
Published: December 2023

This practice report describes a Virtual Exchange (VE), Collaborative Online International Learning (COIL) experience (US and Spain) titled Identity Matters: Culture, Ethnicity, and Race in Literature. It describes the formation of students’ individual and communal identities in the virtual literary classroom. The Spanish students were perusing a BA in English Studies, and the American students were studying various Arts and Sciences BA degrees. Both courses were based in American English literature, so this VE course was conducted in English because the Spanish students were required to do their coursework in English. Students read American short stories/poems about the identities of American/American immigrant characters from different racial backgrounds: African American, Indigenous, Asian, and Latinx. The texts portrayed characters dealing with identity crises: racial, ethnic, and types of discrimination in contemporary American society. Students were prompted to discuss their individual identities and, when placed in a group, their communal identities with identity charts, in relation to the characters’ identities and discriminatory experiences. However, although some students discussed race (social/biocultural construct) in their individual charts, racial cognizance was missing in the group charts and they discussed differences in terms of ethnicity (national/cultural: ancestry, language, beliefs). Additionally, because of these results, we believe that intercultural communication in VE should create/provide a space for race cognizance, among international identities, to better understand the different contexts of stereotypes, prejudices, racism, and/or discrimination experiences that make up all identities participating in VE. We therefore suggest Kimberlé Crenshaw’s Intersectionality Theory and Urie Bronfenbrenner’s Ecological Systems Theory are possible building-block solutions to this dilemma.

Published: December 2023

In 2022, the Ministry of Education, Culture, Research and Technology (Kemendikbudristek) published an independent curriculum (Kurikulum Merdeka). The role of teachers in the curriculum is very important, including the decisions they make to implement the curriculum. Therefore, research is carried out using literature study methods to find out teacher decision making in the learning process in the implementation of an independent curriculum. Based on the results of the literature obtained, the authors analyze the results of the synthesis of research from five selected articles on decision making on independent curriculum learning activities. The results of the study synthesis are classified in four categories, namely (a) independent curriculum direction towards learning goals; (b) learning process in the implementation of an independent curriculum; (c) decision making in the learning process; (d) linkages of independent curriculum goals and learning processes in teacher decision making. It was found that in the learning process, the role of teachers was very important so that implementation took place effectively. Teachers as learning leaders must be able to make decisions about the learning process that is in line with the objectives of the curriculum.

Authors: Levchin A. M. , Lebedenko A. A. , Ershova I. B. , Rogovtsova A. G.
Published: December 2023

Objective: to study the indicators of the functional state of the body and working capacity in the dynamics of learning in elementary school children with different school success.

Materials and methods: the study included 573 elementary school students. Group I – 82 students with excellent academic performance Group II – 491 children with good academic performance. The vegetative index of Kerdo (VIC), the Rufier test, the Genchi test, and the adaptive index (AP) were determined by the method of F. Halberg. The mental performance of younger schoolchildren was studied using Schulte tables.

Results: the values of VIC in group I children were 2.5–3.5 times higher. The difference in IR between the groups increased, amounting to 32.88% in the 4th grade. The Gencha sample was characterized by lower values (by 1–2 seconds) in group I children. The difference in AP in the 1st grade was 4.73 sec., then in the 4th grade –6.86 sec. The Schulte tables showed higher values of work efficiency, workability and endurance coefficient along with a decrease in speed and strength indicators and physical endurance.

Conclusions: by the end of primary school, the vegetative balance in group I children is between normo- and sympathicotonia. The Gencha test made it possible to establish insufficient resistance of the body to hypoxia. Children of group II demonstrated better adaptive capabilities of the CCC, speed and strength indicators and physical endurance. The data obtained must be taken into account in the pedagogical process with younger schoolchildren and require the development of differentiated recreational activities.
Features of both immune and psycho-emotional factors in the adaptive reactions of first-year students
Authors: Urazmambetov R. T. , Chebotov S. A. , Loboda T. V.
Published: December 2023

Objective: comparative characteristics of indicators of psycho-emotional and immune statuses of first-year students in various conditions of the educational process.

Materials and methods: 2nd groups of first-year students of Rostov State Medical University from the medical and preventive faculty (18 people) and the military training center (17 people) were examined. They were all comparable in age (19 ±1 and 19±2 years), gender (all men), physical condition (corresponded to the I-st health group). The immune status was assessed at the Research Institute of Clinical Immunology using standard methodological approaches. Psychological testing was carried out using the Spielberger-Khanin scale, A. Beck's depression diagnostic methodology, and K. Rogers and R. Diamond questionnaire.

Results: the differences in the immune response system between the compared groups were revealed only in relation to the parameters characterizing innate immunity. In relation to Medical and Preventive Faculty students, the functional capabilities of natural killers in Military Training Centre students are reduced and the expression of one of the most indicative pattern-recognizing receptors by monocytes is diminished. The analysis of the obtained data of the psychological questionnaire showed that the students of the Military Training Centredemonstrate a lower degree of situational and personal anxiety with a lower degree of adaptation in comparison with the first-year students of the Medical and Preventive Faculty.

Conclusion: the immune system indicators responsible for the processes of primary immune response are reduced in military medical students comparing with medical students, which in its turn forms possible prerequisites for the development of clinical manifestations of immune dysfunction. The period of psychological adaptation to the educational process in a medical university is less successful for first-year students of the Military Training Centre. It is necessary to develop measures aimed at increasing the sense of responsibility, psychoemotional and immune adaptation resources.
Polymorphisms of interferon γ and NKG2D receptor genes in predicting vertical transmission of HIV/HCV coinfection
Authors: Khamatova A. A. , Balmasova I. P. , Chebotareva T. A.
Published: December 2023

Objective: to investigate single nucleotide polymorphisms in IFNγ gene variant rs2430561 and in NKG2D gene variant rs2617160 as potential risk factors for mother-to-child viral transmission among HIV/HCV-coinfected women.

Materials and methods: 65 mother-child pairs were examined, divided into 4 groups depending on the child's infection (HIV/ HCV infected, HIV or HCV infected, not infected). Methods: multiplex polymerase chain reaction (PCR), PCR for determining the viral load of HIV and HCV, flow cytometry for immunological studies, statistical analysis.

Results: the single nucleotide polymorphism in IFNγ gene variant rs2430561 had no prognostic value when determined in the mothers. When recording the TT and AT genotypes of a single nucleotide polymorphism in this gene in a child, it was combined with the probability of the child's infection with HIV/HCV, HIV or HCV, depending on the magnitude of the viral load of HIV and HCV in the mother's blood in different trimesters of pregnancy. The presence of the AA and AT genotypes of the NKG2D gene variant rs2617160 in the mothers had a prognostic value as contributing tothe child infection with HIV/HCV or HIV alone. It was noted that the mechanisms of perinatal viral transmission included a certain level of decline in the absolute number of CD4+ lymphocytes in the woman blood in the second and third trimesters of pregnancy.

Conclusions: the presence of AA and AT genotypes of the NKG2D gene variant rs2617160 in woman co-infected with HIV/HCV makes it possible to predict the risk of child infection not only during pregnancy, but also at the planning stage.
Clinical observation of early prenatal diagnosis of the coronary of hypospadias
Authors: Tyo S. A. , Turkina O. S.
Published: December 2023

Hypospadias is one of the most common congenital malformations of the male external genitalia and urethra, the main manifestation of which is meatus dystopia. There is a steady increase in the frequency of its occurrence in many countries of the world. Hypospadias have various forms of severity, which significantly affects the patient's management tactics, the volume of surgical treatment and the further prognosis for the boy's life. The article describes a case of early prenatal diagnosis of the coronary form of hypospadias in the fetus at 15 weeks of gestation, followed by postnatal verification of the diagnosis. The possibilities of echography in the early detection of distal forms of hypospadias using an integrated approach in the assessment of external genitalia in a male fetus are shown. This complex of hypospadias markers includes an assessment of the size of the penis, the presence of a curvature of its body, the shape of the head of the penis and the presence of signs of cleavage of the foreskin, which are manifested by its rounding. The ineffectiveness of the long-used «tulip» sign for the early diagnosis of distal forms of hypospadias has been demonstrated. The comparison of the echographic picture of the structure of the genitals in normal and hypospadias at 12 and 15 weeks of pregnancy was carried out.
Making Sense of the Empire’s Others:Mikhail Chulkov’s Dictionary of Russian Superstitions and the European Enlightenment
Authors: Holden W. Forrest
Published: December 2023

This article is an analysis of Mikhail Chulkov’s Dictionary of Russian Superstitions, published in 1782. It places the dictionary in the historical and cultural context of Enlightenment Europe, from which the genre was drawn, and suggests that Chulkov’s use of the genre was part of his own efforts to fashion himself as a civilized, Enlightened man. The article considers the various practices and beliefs described in the dictionary and lays out the various categories of people those which “superstitious” practices and beliefs were ascribed. By comparing the various categories of people described in the dictionary, the article argues that Chulkov’s vision of the Others of the Russian Empire was characterized by a sympathy towards Orthodox Christians and a skepticism about the ability of non-Orthodox subjects of the empire to become civilized. It also considers how Chulkov’s treatment of women and Old Believers reveals his own anxieties about the persistence of superstition into an ostensibly Enlightened era of history.
К истории концепта “Общество как государственное установление”: Памяти Дитриха Гайера (1928-2023)
Authors: Лавринович Майя , Ширле Ингрид
Published: December 2023

Dietrich Geyer’s article “‘Gesellschaft’ als staatliche Veranstaltung. Sozialgeschichtliche Aspekte des russischen Behördenstaats im 18. Jahrhundert,” had a significant impact on both German and American historiography, which is not the case with the Soviet historiography of the 1960-1980s. Nevertheless, late Soviet and early post-Soviet historiography was preoccupied with the same problems of the relationship between “state” and “society” in Imperial Russia and sometimes followed the line of D. Geyer’s thinking. In the 1990s, when the “grand narrative” of modernization was called into question, historians engaged in a polemic about the very productiveness of the opposition of “state” and “society” as categories of historical knowledge. They turned to the local level of late imperial Russian society, or adopted new methods of examining legislative sources, avoiding access to “backwardness” or “underdevelopment,” preferring to examine the language and rhetoric of eighteenth-century documents.
“Общество” как государственное установление. Социально-исторические аспекты российской государственной власти в XVIII веке
Authors: Гайер Дитрих , Лавринович Майя
Published: December 2023

In 1966, Dietrich Geyer published an article on the subject of state-society relations in eighteenth-century Russia, which appeared again in 1975 in an updated form. Geyer placed Catherine II’s reform policy in a European context and asked about the policy of absolute monarchies towards corporative structures and the conditions for the development of civil societies. In the Russian case, Catherine II created “societies” in the form of noble and urban corporations in order to expand provincial administration. According to Geyer’s thesis, both the statist origins of these corporate estates and the connection between noble societies and provincial administration hindered the emergence of a dualism between state and society in Russian history.

Testing Behavioral Messages to Increase Recruitment to Health Research When Embedded Within Social Media Campaigns on Twitter: Web-Based Experimental Study
Authors: Stoffel Sandro T , Law Jing Hui , Kerrison Robert , Brewer Hannah R , Flanagan James M , Hirst Yasemin
Published: December 2023

Background

Social media is rapidly becoming the primary source to disseminate invitations to the public to consider taking part in research studies. There is, however, little information on how the contents of the advertisement can be communicated to facilitate engagement and subsequently promote intentions to participate in research.

Objective

This paper describes an experimental study that tested different behavioral messages for recruiting study participants for a real-life observational case-control study.

Methods

We included 1060 women in a web-based experiment and randomized them to 1 of 3 experimental conditions: standard advertisement (n=360), patient endorsement advertisement (n=345), and social norms advertisement (n=355). After seeing 1 of the 3 advertisements, participants were asked to state (1) their intention to take part in the advertised case-control study, (2) the ease of understanding the message and study aims, and (3) their willingness to be redirected to the website of the case-control study after completing the survey. Individuals were further asked to suggest ways to improve the messages. Intentions were compared between groups using ordinal logistic regression, reported in percentages, adjusted odds ratio (aOR), and 95% CIs.

Results

Those who were in the patient endorsement and social norms–based advertisement groups had significantly lower intentions to take part in the advertised study compared with those in the standard advertisement group (aOR 0.73, 95% CI 0.55-0.97; P=.03 and aOR 0.69, 95% CI 0.52-0.92; P=.009, respectively). The patient endorsement advertisement was perceived to be more difficult to understand (aOR 0.65, 95% CI 0.48-0.87; P=.004) and to communicate the study aims less clearly (aOR 0.72, 95% CI 0.55-0.95; P=.01). While the patient endorsement advertisement had no impact on intention to visit the main study website, the social norms advertisement decreased willingness compared with the standard advertisement group (157/355, 44.2% vs 191/360, 53.1%; aOR 0.74, 95% CI 0.54-0.99; P=.02). The majority of participants (395/609, 64.8%) stated that the messages did not require changes, but some preferred clearer (75/609, 12.3%) and shorter (59/609, 9.7%) messages.

Conclusions

The results of this study indicate that adding normative behavioral messages to simulated tweets decreased participant intention to take part in our web-based case-control study, as this made the tweet harder to understand. This suggests that simple messages should be used for participant recruitment through Twitter (subsequently rebranded X).

Health and e-Health literacy among diabetic patients in low-income countries: an evaluation study in Guinea and Burkina Faso (Preprint)
Authors: Ouedraogo Ismaila , Some Borlli Michel J , Benedikter Roland , Diallo Gayo
Published: December 2023

BACKGROUND

Diabetes is a significant health concern in sub-Saharan Africa, emphasizing the need to assess the health literacy and eHealth skills of hospitalised diabetic patients. This study evaluated the health literacy and eHealth literacy of diabetic patients in Donka Hospital (Guinea) and Sanou Sourou Hospital (Burkina Faso), providing insights for targeted interventions and mHealth solutions to improve self-management and treatment outcomes.

OBJECTIVE

To evaluate and understand the levels of health literacy and eHealth literacy among patients at Sanou Sourou Hospital in Burkina Faso and Donka Hospital in Guinea.

METHODS

The study included 45 participants from Donka Hospital and 47 from Sanou Sourou Hospital. The data collection was conducted in May 2022, and the study focused on examining variables such as gender, age, education, income, and technology access. Health literacy and eHealth literacy were measured using the Brief Health Literacy Screen (BHLS) and the eHealth Literacy Scale (eHEALS) scales, and statistical analysis was performed using SPSS 28.

RESULTS

Results indicated that 64.4% of participants in Donka Hospital and 57.4% in Sanou Sourou Hospital were female. The majority of participants (48.9% in both hospitals) were aged between 25 and 50. Illiteracy rates were high, with 62% in Donka Hospital and 59% in Sanou Sourou Hospital. Smartphone ownership was prevalent, with 62.2% in Donka Hospital and 63.8% in Sanou Sourou Hospital. Participants reported occasional use of technology for basic purposes and frequent internet usage for accessing health information. However, a significant proportion of participants demonstrated low health literacy (73.3% in Donka Hospital, 78.5% in Sanou Sourou Hospital) and inadequate eHealth literacy (57% in Donka Hospital, 61.7% in Sanou Sourou Hospital). Education positively correlated with health literacy, while age displayed a moderate negative correlation. Weak correlations were observed between gender, income, and health literacy, but these were not statistically significant. No significant correlation was found between the Brief Health Literacy Screen (BHLS) and the eHealth Literacy Scale (eHEALS) scores in either hospital.

CONCLUSIONS

This study highlights the importance of targeted educational interventions and mHealth solutions to enhance health and eHealth literacy among hospitalized diabetic patients. Addressing health literacy and eHealth literacy is crucial for improving diabetes management and treatment outcomes in Guinea and Burkina Faso. Targeted interventions and mHealth solutions can empower patients, enabling their active involvement in healthcare decisions.

DPPH Scavenging Activity, Reducing Power, and Metal Chelating Capacity of Compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone
Authors: Wibowo Andy Eko , Octa Ujiantari Navista Sri , Susidarti Ratna Asmah
Published: December 2023

Background: The excessive free radicals in the body could stimulate oxidative stress which has been implicated in several diseases such as cancer, inflammation, aging, and cardiovascular diseases. The presence of antioxidants can diminish the reactivity of free radicals. The antioxidant defense system in the body may be insufficient thus intake of dietary antioxidants is recommended. Natural flavonoid such as chalcone has been known to exert several biological activities, especially antioxidant activity.  Compound 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone was successfully synthesized using microwave radiation and several studies reported its biological activities such as antiinflammation, anticancer, and antibacterial activities. Those activities are thought to be related to antioxidant mechanisms. Therefore, this study aimed to evaluate its antioxidant activity. Methods: The antioxidant activities were performed with three different methods: DPPH scavenging activity, ferric reducing power, and metal chelating capacity. Results: 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone showed DPPH scavenging activity, ferric reducing power, and metal chelating capacity with IC50S values of 4,471 ± 0,052 μg/mL; 156.56 ± 4.42μg/mL; and 6,273 ± 0,025 μg/mL, respectively. Conclusions: Our results found that 1-(2,5-dihydroxyphenyl)-3-pyridine-2-yl-propenone had quite potent antioxidant activity.
Molecular Docking Study of Caffeic Acid as Acetylcholinesterase Inhibitor
Authors: Wira Waskitha Stephanus Satria , Istyastono Enade Perdana , Octa Riswanto Florentinus Dika
Published: December 2023

Abstract: Acetylcholinesterase (AChE) receptor is a receptor that has been widely used as a potential drug target for Alzheimer's disease. Caffeic acid is a phenolic compound that had been experimentally proven to be an inhibitor of AChE. In this study, 100 molecular docking simulations were performed to study the interaction of caffeic acid in inhibiting AChE. The molecular docking simulations were performed using YASARA software with an in-house developed plug-in. Redocking results showed that there were 99 out of 100 docking poses had an RMSD value of ≤ 2.000 Å, which indicated that the molecular docking procedure could be used for further processes. The molecular docking of caffeic acid showed that all docking poses had an RMSD value of ≤ 2.000 Å relative to the best pose of the first simulation, revealing that there was only one dominant docking pose in the AChE active site. Caffeic acid interacted favorably in the AChE active site with binding energy of about -8.022 kcal/mol. Its interactions were stabilized by hydrophobic and pi-anion interactions, in which some of the interactions resemble the same interaction of the native ligand.

Keting fish (Mystus gulio) is a local fish from Indonesia. The quality of keting fish oil needs to be maintained to avoid counterfeiting. The use of Fourier transform infrared (FTIR) spectroscopy can be developed for quantitative analysis of keting fish oil (KFO) in binary mixtures with palm oil (PO) and patin fish oil (PFO). In this present research, PLS and PCR models were used to construct a multivariate calibration for the KFO content in the binary mixtures analyzed at fingerprint region frequencies of 1500-1000 cm-1. The results showed that PLS with second derivative FTIR spectra was well suited for quantitative analysis of KFO-PFO with a value of the coefficient of determination (R2) = 0.997 and the error expressed as root mean square error of calibration (RMSEC) = 0.0204. Meanwhile, R2 0.999 and RMSEC values obtained for KFO in a mixture with PO were and 0.0133. In general, FTIR spectroscopy serves as a suitable technique for the determination of KFO in mixtures with other oils.

Published: December 2023

Salah satu masalah di industri perminyakan yaitu pompa yang digunakan untuk mengirimkan fluida, mengalami penebalan akibat scaling pada sudu sehingga menyebabkan perubahan geometri sudu impeler pompa. Dalam penelitian ini dilakukan pemodelan pengaruh variasi penebalan scaling pada sudu terhadap kinerja pompa sentrifugal. Simulasi computational fluid dynamics (CFD) dilakukan menggunakan ANSYS Fluent. Variasi berupa penebalan scaling pada sudu cekung merata pada sudu menjadi 3 mm, 4 mm dan 5 mm, dan penebalan scaling cekung tidak merata bagian tengah dan ujung sudu. Hasil simulasi variasi scaling sudu cekung merata terlihat bahwa dengan meningkatnya ketebalan menjadi 3 mm, 4 mm dan 5 mm, terjadi penurunan head pompa. Pada penebalan scaling cekung tidak merata bagian tengah sudu terjadi penyempitan yang signifikan di laluan impeler yang menyebabkan banyak aliran sirkulasi di area setelah penebalan. Semakin bertambahnya penebalan scaling meyebabkan pengarahan fluida menjadi kurang efektif mengakibatkan terjadi kehilangan sebagian energi kinetik sehingga head menjadi lebih rendah.

Mechanical Properties and Corrosion Characteristics of Dissimilar Friction Stir Welded AA1000/AA6061-T6 Aluminum Alloys
Authors: Sokvisal Chhorn , Ilman Mochammad Noer
Published: December 2023

This paper is aimed to investigate microstructure, corrosion and mechanical properties of dissimilar metal weld joints between AA1000 and AA6061-T6 under different tool rotational speeds of 910, 1500, and 2280 rpm at a constant transverse speed of 30 mm/min. Several experimental works have been conducted including microstructure observation using optical microscopy and Scanning Electron Microscopy (SEM) equipped with Energy Dispersive X-ray Spectroscopy (EDS), Vickers microhardness measurements, tensile tests, and corrosion measurements using Potentiodynamic Polarization method. Results show that increasing tool rotational speed from 910 rpm to 1500 rpm increases the degree of homogeneity in nugget zone and improves strength of the weld joint but further increase in the tool rotational speed up to 2280 rpm degrades the mechanical properties due to coarsening of the microstructure. Furthermore, corrosion rate of the nugget zone (NZ) is in between the two base metals.
A Quantitative Study on Undergraduate Students’ Deeper Learning in Peer-Feedback and Self-Feedback Tasks in an English as a Foreign Language Writing Course
Authors: Wen Danping
Published: December 2023

Deeper learning competencies, such as critical thinking, communication, collaboration, and self-management, are receiving increasing attention in education. In writing instruction, feedback-providing tasks have the potential for promoting deeper learning. This study develops and applies a self-report scale to explore the level of deeper learning among undergraduate students in China in providing peer feedback and self-feedback in an English as a Foreign Language (EFL) writing course. The scale includes three dimensions: involvement, use of deeper learning strategies, and deeper learning outcomes. The research found a generally moderate level of deeper learning in various feedback-giving tasks. Significant and positive correlations were found between the three dimensions of deeper learning as well as between deeper learning, anticipation toward feedback-giving tasks and overall course evaluation. At the same time, it was found that students may be more active in deeper learning from the perspectives of their use of deeper learning strategies and the perceived learning outcomes than from the perspectives of participation in discussion as well as time and effort spent on the tasks.

Published: December 2023

Malaysia is currently one of the most popular study destinations for overseas Chinese students. At the same time, due to global educational status and better media technology facilities, including social media, more Chinese students tend to live or study abroad. However, the different patterns of social media at home and abroad have created a cognitive gap among overseas Chinese students in Malaysia. Qualitative in-depth interviews and Focus group discussions with more than a dozen overseas Chinese students studying in Malaysia showed that social media use has multiple impacts and aids in structuring learning, lifestyle influences, and the relationship between social media use and cognitive formation. The findings suggest that China’s local social media has been identified as a widespread use by overseas Chinese students for cross-border daily interpersonal communication. It not only helps to construct the lifestyle of overseas Chinese students, but also helps maintain their social perception as “Chinese” by generating the image of home.

Abstract: Software defect prophecy work focuses on the number of faults remaining in a software system. A prophecy of the number of remaining scars in an audited artefact can be used for decision timber. An accurate prophecy of the number of scars in a software product during system testing contributes not only to the operation of the system testing process but also to the estimation of the product’s demanded conservation. amiss software modules beget software failures, increase development and conservation costs, and drop customer satisfaction. It strives to meliorate software quality and testing effectiveness by constructing predictive models from law attributes to enable a timely identification of fault-prone modules. In this design, we will explore machine knowledge ways for software defect prophecy . This helps the formulators to descry software scars and correct them. Unsupervised ways may be used for defect prophecy in software modules, more so in those cases where defect labels are not available.
