https://www.ijirss.com/index.php/ijirss/article/view/3485
<p>The purpose of the study is to explore how the promotion of news media literacy positively affects media criticism as well as the control and judgment of self-behavior. Potter developed the Chinese News Media Literacy Scale (NMLS), based on his theoretical framework of media literacy cognition. Potter is an outstanding scholar in media literacy. Senior high school students in Taiwan validated the NMLS for reliability and validity. The NMLS consists of 45 questions covering four topics: intellectual skills, personal locus, media knowledge structure, and news context reading. The Chinese version of the NMLS demonstrated good reliability, considerable validity, appropriate discrimination, and an appropriate level of difficulty, making it suitable for Taiwanese students. Female respondents exhibited higher news media literacy than their male counterparts. Public senior high school students showed higher news media literacy compared to those from private schools. The time spent reading news positively correlates with improvements in news media literacy. The findings indicate that news media literacy education significantly enhances students' critical understanding of news and media literacy skills, with varying effects across different genders and types of schools. The limitation of the study is that the sample mainly comes from Taiwan, which may not fully represent other cultural contexts. The findings can guide educational policy in schools, particularly in designing and implementing news media education curricula, taking into account the differences in gender and school types. This research expands the literature on news media literacy, especially in terms of scale development and its application to a specific cultural context like Taiwan, and introduces new insights into the impact of gender and school type on media literacy.</p>Huang Chao-HsiCheng Ping-HanHsieh Tsung-ShunChang Kuo-En

https://www.ijirss.com/index.php/ijirss/article/view/3537
<p>This study investigates the impact of international migration on the Bini people of Edo State, Nigeria who are renowned for their rich cultural heritage, arts and historical migration patterns. The primary objective is assessing how international migration affects their economic and social life. This study posits that migration is primarily motivated by the search for better employment opportunities with individuals making well-considered decisions to enhance their economic prospects using neoclassical theory. Furthermore, the new economic migration theory is applied to examine the broader impacts of migration on the Bini community’s lifestyle in Edo South. Data for this research were gathered through focused group interviews and structured questionnaires. A linear regression analysis was conducted to assess the role of remittances in the community’s economic dynamics. The analysis indicates that remittances are crucial in shaping the Bini people’s economic activities. It also suggests that these remittances should be strategically invested in business ventures to maximise the benefits. This study concludes that international migration plays a significant role in improving the livelihood of the Bini people enhancing their economic stability and growth. The findings highlight the need to channel remittances effectively into productive investments to benefit the community. The Bini people can better leverage the economic advantages provided by international migration leading to sustained community development and economic resilience by strategically investing in business ventures.</p>Ehiagwina Sunday BraimahDaniel Eseme GberevbieFelix ChidozieGoddy Uwa Osimen

https://www.ijirss.com/index.php/ijirss/article/view/3569
<p>This study investigates operational and production determinants that significantly influence small-scale transitioning to commercial farming among female agripreneurs, the implications for food security and gender equality with various elements impacting the commercialization of agricultural production in emerging economies. A quantitative research design was used in this research. This study was conducted in the emerging economic zone, the Vhembe district of Limpopo province where agricultural activities dominate. A purposive sampling was used to select 149 female agripreneurs. Structured questionnaires were handed to the participants during the in-person interview sessions. The study results reveal that the sample was dominated by elderly agripreneurs who primarily relied on permission to occupy arrangements for land security. The study findings exhibit that operation determinants such as type of farming and record keeping were positive contributors towards commercialization among female agripreneurs. Meanwhile, production elements such as commodity types regressed the commercialization effort among female agripreneurs. The study findings imply that policy tools should advocate for land security among female agripreneurs as they enhance the implementation of their long-term agricultural plans. The study findings suggest that emerging female agripreneurs should be made aware of various farming types that propel commercialization within a shorter period due to their lifecycle.</p>Mpho TshikororoTakalani Isaac Khorombi

https://www.ijirss.com/index.php/ijirss/article/view/3570
<p>The purpose of the article is to compare the efficiency of using electro-pulse and ultrasonic mufflers for cleaning exhaust gases from internal combustion engines of automobiles. The authors have developed full-size stands for conducting experiments with both types of mufflers on gasoline and diesel engines. Experimental studies have shown that electro-pulse mufflers are more effective in reducing the smoke of diesel engine exhausts, while ultrasonic mufflers are promising for cleaning exhaust gases from solid particles of gasoline engines. In the electro-pulse muffler, at the considered values of the angular velocity of the engine, the smoke indicators of the gas decreased to approximately 30%, while in the ultrasonic one, to 15%. The changes in the mass of the sold particles in the ultrasonic muffler of a diesel engine and a comparison with a gasoline engine show that ultrasonic mufflers have a lot of potential to stop solid particles from forming in the gas flow. In particular, the mass of the precipitated particles in a gasoline engine is 3 times greater than in a diesel engine. The alternative mufflers studied in the article allow for the purification of exhaust gases from solid particles, reducing their negative impact on the environment and giving impetus to the development of environmentally friendly motor transport.</p>Adil KadyrovBauyrzhan SarsembekovAliya KukeshevaKirill Sinelnikov

https://www.ijirss.com/index.php/ijirss/article/view/3571
<p>This study adopted a quantitative approach to explore learning adjustment in terms of the students’ perceived adjustments in teaching, cognitive and social presence in the community of inquiry (CoI) framework from face-to-face classroom to online learning, and then from online to blended learning in the case of a higher education institution in Hong Kong. The online CoI survey was conducted to collect data from a convenience sample of 212 participating students who experienced the transition from classroom to online learning, and then the transition from online to blended learning in the case of the higher education institution. Analysis of variance, pairwise comparisons, correlation and multi-group analyses were performed on the collected data. The analytical results indicated that the students perceived four adjustments in their CoI presences in the online classroom and blended learning. (1) Classroom learning exhibited the strongest CoI presence while online learning rendered the weakest CoI presence. (2) Cognitive presence was the most important while social presence was the least important for learning. (3) All correlations among the CoI presence were positive with large correlations in online and blended learning modes. (4) All the teaching, cognitive and social adjustments were positively and largely correlated. These findings provide implications for further studies on exploring the explanation for the student’s learning adjustment and investigating the learning improvement strategies for online education.</p>Simon WongYuk Ming TangPat ChanYui-Yip LauAnthony Loh

https://www.ijirss.com/index.php/ijirss/article/view/3572
<p>This article analyzes the factors that can influence employee performance at Regional Owned Enterprises (ROE), Klaten Regency, Indonesia. The factors tested in this research are the influence of religiosity, organizational culture, internal control, discipline, and incentives on employee performance. This research focuses on all active employees at Klaten Regency Regional Owned Enterprises (ROE). The sample in this study consisted of 110 respondents from various departments and various types of employees and was analyzed using the Partial Least Squares (PLS) program. The results of this research indicate that the religiosity and incentive variables have no impact on employee performance. It can be said that the influence of religiosity will not be able to improve employee performance, and this research found that the problem of religiosity is a personal problem that is not related to work. Meanwhile, incentives are not able to boost employee performance because employees feel satisfied with what they have received. The variables of organizational culture, internal control and discipline, will significantly improve employee performance. So, this research provides implications regarding the importance of emphasizing a good organizational culture by management for all members of the organization as well as continuing to implement a good internal control system and not ignoring employee work discipline.</p>Sigit HandoyoHeppy Yuniartha PurwitasariEndah Utami

https://www.ijirss.com/index.php/ijirss/article/view/3573
<p>Organisations are currently facing challenges due to internationalization and fundamental shifts in industries worldwide. The Nigerian banking sector is experiencing exceptional difficulties and competitive forces such as the issue of managerial decisions, perceptions of inequality, unfair treatment and a poor connection between individuals and their work environment. As a result, this study aims to acquire improved knowledge of how organisational justice and climate variables influence employee engagement in this industry. This investigation took a descriptive research technique. There were 361 questionnaires issued but only 332 were returned. 91.97% of the questionnaires examined were returned which is considered satisfactory for this study. Descriptive statistics were analysed using Statistical Packages for the Social Sciences (SPSS) while inferential statistics were used to evaluate the generated hypothesis using SEM-PLS. The findings showed that organisational climate does not moderate the relationship between organisational justice and employees' commitment but organisational justice has a direct relationship with employees' commitment. It can be concluded that organisational climate does not moderate the relationship between organisational justice and employees' commitment. Organisational stakeholders should make informed choices and implement successful strategies to improve employee well-being and organisational outcomes by understanding the relationship between organisational justice and employees' commitment.</p>Olanrewaju, Kofoworola MisturatAdeniji Anthonia Adenike

https://www.ijirss.com/index.php/ijirss/article/view/3574
<p>The main purpose of this article is to study the structural characteristics of carbon fiber samples printed on a 3D printer, including embedded sensors, during 3D printing, through numerical and experimental studies. There is a widespread tendency to replace metals with modern composite materials. Various methods can be used to measure the destruction of the composite structure. Fiber Bragg array sensors are known as intelligent localized and global structural condition prediction devices for all kinds of structural applications, especially those using composite materials. In this work, we created control plates by impregnating a selected number of layers of carbon fabric with epoxy resin. Fiber-optic Bragg sensors were additionally located between the layers of carbon fabric. In the course of experimental studies, a fiber Bragg grating sensor was embedded in the middle of the sample, and a second sensor was attached to the finished surface of the sample. We conducted environmental tests to examine the durability of the additively manufactured standard’s components and the impact of integrated sensors on the composite sample. We applied the concept of equations, known as conjugate modes, and used the transition matrix method to solve them numerically. The scientific novelty of the work is the development of a new method and technology for measuring spatial deformation in composite materials using fiber-optic Bragg gratings.</p>Aliya KalizhanovaAinur KozbakovaMurat KunelbayevBeibut AmirgaliyevZhalau Aitkulov

https://www.ijirss.com/index.php/ijirss/article/view/3575
<p>This study examines the iron bed accelerator for discharging cylindrical NCA batteries in salt solution. The use of Li-ion batteries has increased due to the rise of e-mobility in computers, cell phones, and electric vehicles. Recycling Li-ion batteries for raw material in lithium-ion battery production is increasingly important as the revolution unfolds. When disposing of, transporting, and recycling the battery, it is important to crush it to separate the black mass, plastic, and metal components. However, there is a potential explosion risk due to the remaining voltage in the battery. In recycling, the discharge step is significant. The research aimed to test a new method for discharging cylinder batteries using saltwater and an iron bed. Higher NaCl content increases pH and lowers electrochemical potential for water electrolysis. This unique combination enables the battery to discharge at a high rate. In 6 hours, the battery discharged in a 20 wt.% salt solution with 99.6% efficiency. The battery discharge efficiency decreased when exposed to 25 wt% and 30 wt% salt solutions, attributed to reduced water electrolysis intensity. According to the results of various experiments, it has been observed that as the temperature of the salt solution rises, there is a slight increase in the rate of battery discharge; however, no significant difference has been observed. This article talks about how batteries are discharged. It shows the electrochemical reaction using the Eh-pH diagram for Fe-Na-Cl. It also has a schematic diagram that shows the process and a chemical analysis of the precipitate that forms during the discharge test.</p>Erdenebold UrtnasanJei-Pil Wang

https://www.ijirss.com/index.php/ijirss/article/view/3576
<p>This paper recognizes the gaps in previous studies and provides insight into the significance of leadership guided by ethical principles in influencing employee engagement through the mediating role of perceived organizational support (POS). Thus, this paper aims to examine the impact of ethical leadership on employee engagement and to determine whether perceived organizational support (POS) mediates the relationships between both constructs. This study used a quantitative research method and collected data from 328 employees in the Information and Communication Technology telecommunications sector in Palestine. The hypotheses underwent examination through the application of partial least squares structural equation modeling (PLS-SEM). The findings show that 328 people responded to the current study's questionnaire. Ethical leadership the dependent variable was strongly impacted by perceived organizational support (EL POS) at the significant level of 0.01 (β = .697, µ =.0.669, SD=0.035, t=20.104, P=0.000 and f^2= 78% respectively. All of the study's variables had some effect on the dependent variable and employee engagement. Similarly, the remaining hypotheses are verified. When the R-squared adjusted values of the independent variables for the variance of employee engagement were more than 53 percent, the R-squared multiple correlations (R2) for the dependent variables indicated that the model appropriately matched the data.</p>Mohammed IF DawwasMohammed AlzoraikiAli AteeqQais AlMaamariMarwan Milhem

https://www.ijirss.com/index.php/ijirss/article/view/3577
<p>The purpose of this study is to evaluate internship programs in Japan held by Japanese departments at universities in Indonesia as an implementation of the Indonesian Ministry of Education and Culture's policy on independent study on campuses in 2020, examining the students’ culture shock level and the difficulties they encountered during the internship program. This study used a mixed-methods approach with case studies. We used quantitative data to measure the students’ culture shock level, and qualitative data to uncover the difficulties they encountered. Data were collected through a questionnaire, and a semi-structured interview with 100 intern students took place. This research found that Indonesian intern students’ culture shock was at a moderate level and encountered difficulties due to language, job performance, Japanese work culture, negative local attitude toward intern students, and the intern's personalities such as low adaptability and lack of confidence. This study also found that all of the students at each level of culture shock faced difficulties in performing jobs because of their low Japanese ability and work culture differences, but student personalities and locals’s responses are the determinants of the student’s culture shock level. The implications of this study highlight the need for an evaluation of Japanese language and culture learning curricula and methods in Indonesia.</p>Pitri HaryantiAgus Suherman SuryadimulyaReiza DienaputraTajudin Nur

https://www.ijirss.com/index.php/ijirss/article/view/3579
<p>International organizations’ analyses of Mexican students have shown that the nation's educational system is currently facing significant challenges in its ability to support the development of academic skills at all educational levels. Evaluations carried out by international organizations on Mexican students have revealed that the educational system in this country currently presents serious difficulties in effectively contributing to the development of academic skills at all educational levels. Models that consider learning styles and other factors that support academic performance such as intrinsic motivation, mastery goals, beliefs, control and Regulation of the Value of Tasks (RVT) have been developed since the last century to improve the skills of both high school and university students. A quantitative, non-experimental, cross-sectional, descriptive and correlational study was conducted to identify the relationship between Regulation of the Value of Tasks (RTV) and learning style (LS). RTV data collection used the motivated strategies for learning questionnaire while EA was assessed using the Honey-Alonso Learning Styles Questionnaire (CHAEA). The study involved 108 university students enrolled in a public institution located in southeastern Mexico. The results indicate a "very weak" relationship between SRL and the active, pragmatic and theoretical learning styles. According to the literature review conducted for this study, there are very few similar investigations making it difficult to compare the results with previous data. Further research is suggested to explore the relationship between these variables in other populations.</p>Juan Pablo Sanchez-DominguezAngel Esteban Torres-ZapataTeresa del Jesus Brito-CruzManuel Antonio López-Cisneros

https://www.ijirss.com/index.php/ijirss/article/view/3580
<p>This research aimed to examine the characteristics of tourism entrepreneurs and their impact on performance in the Gocta destination. This study analysed data from a sample of 47 entrepreneurs using structural equation modelling with SmartPLS 3.37 software using a quantitative methodology with descriptive and explanatory approaches. The sample included 44% men and 55% women. The sample included 44.7% men and 55.3% women. The results indicated that entrepreneurial traits such as leadership (p=0.047), planning (p=0.041) and innovation (p=0.007) have a significant positive effect on both entrepreneurial performance and business sustainability. These characteristics are decisive for improving business performance and ensuring long-term viability. In contrast, business attributes such as sociability (p=0.065) and sustainability (p=0.557) showed a lower level of significance about performance. This indicates that they are less critical compared to leadership, planning and innovation although sociability and sustainability are valuable. The study highlights the importance of these key traits in driving entrepreneurial success and aims to strengthen the skills associated with leadership, planning and innovation among entrepreneurs. This research seeks to support the development of effective and sustainable tourism enterprises in the Gocta destination and provides valuable information for both entrepreneurs to consider the entrepreneurial characteristics of starting a great business and policy makers by focusing on these traits.</p>Manuel Antonio Morante DávilaMaritza Revilla BuelothEdinson Cueva VegaOscar Chavez EspinozaWilliam Chavez Espinoza

https://www.ijirss.com/index.php/ijirss/article/view/3582
<p>This study examines the development of an intelligent geographic information system for mountain road monitoring. To make well-informed and timely management decisions in the planning, construction, and maintenance of mountain roads, and to anticipate potential critical situations and their effects on road conditions, it is imperative to employ modern methodologies. This study involves data collection from a specific section of a mountain road situated near Almaty, Kazakhstan. We gathered data on the road section through visual assessment, measurements of the coefficient of adhesion, and the acquisition of material samples from the structural layers of the roadbed. Based on the visual assessment and surface adhesion measurements, it became evident that the deformation of the studied road section, which includes a network of cracks and "non-standard" transverse cracks, is attributed to mountain mass shifts and water flows from slopes. Laboratory analysis of the collected samples revealed that excessive water saturation could result in cracks during freeze-thaw cycles, while a low resistance coefficient would lead to softening during humid conditions. An Intelligent Geographic Information System (IGIS) will incorporate the collected data alongside open remote sensing and weather data. The objective is to utilize this integrated system in the future for forecasting road conditions and maintenance requirements for similar roads in mountainous regions of the area. The measurements are carried out according to the state standards. That makes the system useful for government management purposes.</p>Gulnara NurpeissovaAinur KairanbayevaSerik NurakynovDina PanyukovaKerey Panyukov

https://www.ijirss.com/index.php/ijirss/article/view/3583
<p>The purpose of this study is to check the intellectual capital's role in shaping green process innovation. This article contends the company's capacity to create, possess, incorporate, and implement environmentally friendly intellectual assets in its activities will result in a higher degree of performance in terms of innovative green processes. This performance serves as an indicator of the company's enduring dedication to an environmentally conscious strategy. The industries chosen for this study comprised textile, chemical, pharmaceutical, and steel based in Mexico. The random sampling technique was used to gather data. Upon analyzing the gathered data, we used only 253 questionnaires for analysis, representing a response rate of 42.7%. Findings indicate green strategic intent significantly influences three components of intellectual capital: human, relational, and organizational capital. Three components of intellectual capital significantly influence green process innovation. A green strategy can be successfully implemented by the implementation of intangible resources. Mere tangible resources are insufficient to gain superior green innovation performance; the interaction of these two resources (tangible and intangible) is complementary. Companies are adopting environmental strategies to mitigate the environment's harmful impact and meet stakeholders' demands. The study’s practical implications aim to improve companies’ environmental performance, specifically their green performance, through the implementation of green innovation.</p>Jorge Alberto Esponda PérezElizabeth Emperatriz García-SalirrosasFaisal EjazMd Billal HossainLászló Vasa

https://www.ijirss.com/index.php/ijirss/article/view/3637
<p>This study aims to analyze and describe the various forms of collaborative work that teachers and university students in the province of Cusco accomplish together using the descriptive methodology. All professionals must know their area of work as well as lead in all work environments. The participation was anonymous and voluntary. The participating students are from the first cycle to the third cycle of the different professional careers between males and females from the rural and urban areas of the province of Cusco, Peru. The findings indicate that university teachers play an effective and significant pedagogical role in designing the collaborative work model that assigns group work in their respective classrooms with the various careers they supervise. Additionally, the findings show that the teacher fulfils the social role of motivating students by performing as a tutor in the classroom. Therefore, it has a positive and significant effect among university students. This has implied that the formation of working groups in university students generates student leaders and demonstrates broad knowledge in communication and information technologies which will generate many expectations in their professional training.</p>Valeria-Volodia Salluca-RodriguezLaurem-Amelia Salluca-RodriguezVeronica Luna-CcoaYersi-Luis Huaman-RomaniSandra Salazar-Palomino

2024-10-152024-10-158120221410.53894/ijirss.v8i1.3637Does a business education make for better innovative managers? An empirical examination of CEOs’ business education, CEO duality and R&D investment intensity
https://www.ijirss.com/index.php/ijirss/article/view/3638
<p>This study aims to explore how chief executive officers (CEOs) business education influences their company's investment in Research and Development (R&D) taking into account the moderating impact of CEO duality. Risks related to investment in research and development might have an impact on CEOs who are responsible for improving management effectiveness and company value. Insufficient education among executives can hinder effective oversight. Findings from analyzing data from 1632 firm-year observations from 2015 to 2020 of companies listed on the Shanghai and Shenzhen Stock Exchanges reveal that CEOs with dual roles tend to prioritize R&D investments and innovation. Additionally, CEOs without a Master of Business Administration (MBA) or executive MBA education (EMBA) exhibit a greater willingness to take risks leading to more innovation and spending on R&D. This research emphasizes the need to consider CEOs' demographics, board structures and governance mechanisms to promote innovation in companies.</p>Shehabaddin Abdullah Abdulwadod Al-Dubai

https://www.ijirss.com/index.php/ijirss/article/view/3656
<p>This study aims to evaluate the hepatoprotective effect of erythropoietin against doxorubicin-induced liver damage in a male rat model through PI3K/Akt/GSK3β axis modulation and activation of the Nrf2/HO-1 pathway. Doxorubicin, a chemotherapeutic antibiotic used to treat many types of cancer, has some considerable side effects that limit its clinical use, including hepatotoxicity. Erythropoietin is a glycoprotein hormone primarily recognized for its crucial function in promoting erythropoiesis. Recent studies have demonstrated the significant cytoprotective effects of erythropoietin in several organs. Thirty-six male Wistar rats were randomly separated into six groups: (Group 1) a negative control group; (Group 2) a doxorubicin induction group; (Groups 3, 4, and 5) three groups pre-treated with erythropoietin in three different doses (1000, 3000, and 6000 IU/kg); and (Group 6) a positive control group pre-treated with silymarin (100 mg/kg). On the 7th day, all groups (except group 1) were injected with a single dose of doxorubicin (20 mg/kg). On day 9 of the experiment, blood and liver samples were taken for subsequent analysis. The results showed that erythropoietin pre-treatment significantly reduced doxorubicin-induced hepatotoxicity by stimulating the PI3K/Akt and Nrf2/HO-1 pathways and suppressing GSK3β and caspase 3. In addition to that, erythropoietin pre-treatment also raised the levels of GSH, lowered the levels of MDA, and brought the levels of the liver enzymes ALT and AST back to normal compared to the induction group. In conclusion, via modulating PI3K/Akt/GSK3β and activating the Nrf2/HO-1 pathway, erythropoietin pre-treatment protected the liver against hepatotoxicity caused by doxorubicin in a dose-dependent manner.</p>Zeena Jasim SaddamYassir Mustafa KamalHuda Jaber Waheed

https://www.ijirss.com/index.php/ijirss/article/view/3750
<p>This exploratory research investigates the scientific competence levels among secondary school students in the North Eastern region of Thailand in the post-COVID-19 era and examines the relationship between teachers’ Technological Pedagogical Content Knowledge (TPACK) and students' scientific competency. The study collects data from 76 science teachers and 1878 students representing 76 schools in the northeast of Thailand. The study employs a set of instruments, including 1) the 28 items of the TPACK questionnaire and 2) the scientific competency measurement tool. The findings reveal that the overall scientific competency score among students reflects a moderate level. Specifically, students demonstrated moderate competence in "explaining phenomena scientifically" and "evaluating and designing scientific inquiry," while their ability to "interpret evidence and data scientifically" was found to be at a low level. Furthermore, there is a significant but low-level correlation between the scientific competency of students and the TPACK of their teachers. The findings highlight the urgent need for a pedagogical shift in educational practices. There is a pressing need to design learning experiences that emphasize scientific inquiry and critical thinking rather than focusing solely on subject matter expertise. Strengthening teachers' capacity to integrate technology with pedagogy alongside fostering inquiry-based learning approaches will be crucial in improving students' scientific competencies and preparing them to handle challenging problems in the contemporary world.</p>Kanyarat SonsupapKanyarat CojornSomsong Sitti

https://www.ijirss.com/index.php/ijirss/article/view/3751
<p>This research delves into the influence of marketing on the performance of spa businesses in Slovakia, a sector with a rich historical background and significant potential for growth. This study aims to examine the role of marketing in the spa industry in Slovakia and its impact on the performance of selected spa businesses. This study utilizes regression analysis in statistical software R to assess financial data from twenty-five spa businesses in Slovakia spanning from 2012 to 2022 comprising 198 data points. In addition, the study investigates the use of social media platforms in spa marketing by examining the online communication practices of selected Slovak spa businesses and their international counterparts. The results indicate that although the use of social media in the marketing strategies of Slovak spa businesses is currently limited, marketing expenditures significantly influence the sales of these businesses. This highlights the potential for improved performance through more strategic marketing, particularly digital channels. The limitation of this study is the availability of statistical data in the environment of spa businesses in Slovakia which significantly limits the results of the study. The findings emphasize the importance of effective marketing implementation in the Slovak spa industry with a specific focus on the necessity for increased digitization and the use of social media platforms. This insight is essential for spa businesses seeking to optimize their marketing efforts and enhance overall business performance.</p>Kubickova VieraGall JozefHalenarova Maria

https://www.ijirss.com/index.php/ijirss/article/view/3752
<p>This research evaluates the school operational assistance fund as Indonesian educational funding through the application model. Qualitative research methods were conducted on 10 public senior high schools in Jakarta, Indonesia. Data collection was conducted through content analysis, focus group discussions and interviews. The findings of this study show that in this context, schools understand the legal basis and conduct socialization related to education funding provided by the government. In the input aspect, the school needed to prepare a decree to create an education fund management team according to the existing technical guidelines. Schools also had problems when inputting data into the system provided by the government. As for the process aspect, it was found that the timing of the distribution of school operational assistance funds was not related to the existing regulations. In addition, schools did not have internal supervisors. The implications of this research for education agencies in Indonesia are to pay attention to the suitability of the implementation of education funding with the existing guidelines. It is necessary to evaluate the implementation of the school operational assistance funds policy to improve the quality of education in Indonesia in the coming year.</p>Ali MukodasEndry BoeriswatiBedjo Sujanto
