Extension of value stream mapping 4.0 for comprehensive identification of data and information flows within the manufacturing domain

The main driver of industry 4.0 is data and information for realizing resilient manufacturing systems through data-based decision-making. This requires the data flow from different machinery and its processing. Therefore, a methodical survey on the logical and technical requirements for enabling an efficient data flow can be beneficial since it fastens the process of establishing the data flow and gives production and software engineers a common understanding of the data’s meaning. Hence, data, related metadata like the unit or the frequency of recordings, and technical information, e.g., the machine’s interface or the communication protocol, are necessary. Based on the classical value stream mapping (VSM) as a lean management tool, the first approach for a methodical gathering of data, value stream mapping 4.0, was established in 2016. Since VSM 4.0 provides technical properties for specifying the data flow, some shortcomings were identified, particularly related to technical information. This contribution introduces the VSM 4.0 plus that solved the identified shortcomings by adding new properties. Compared to VSM 4.0, VSM 4.0 plus offers detailed specifications of data points, includes technical information, e.g., used communication protocols, adds information regarding data processing, and enhances the storage and usage dimension by providing more details. Through the added properties, VSM 4.0 plus allows domain and software engineers more efficient collaboration since all required information for establishing the data flow and its processing are united in one methodology. To verify the practicability, the VSM 4.0 plus was applied within several manufacturing-related use cases.

USING TECHNOLOGY ACCEPTANCE MODEL TO ANALYSE THE SUCCESSFUL CROWDFUNDING LEARNING GAME CAMPAIGNS

Due to the limited opportunities for financial supports to educators, Crowdfunding can be an effective channel to solicit funding sources for educators to develop new learning games. Understanding user perceptions of a successful learning game guided by Technology Acceptance Model (TAM) could help educators to effectively adapt Information Communication Technologies (ICT) in developing more competitive learning games and secure more funding. This study used a user survey to assess the success of Kickstarter-funded learning game projects. Guided by TAM, the study derives eight perceived assessment dimensions, including three Usefulness dimensions: Representation mode, Narrative, Interaction; four Usability dimensions: Learning provision, Skill building, Rules, Assessment; and one Acceptance dimension: Motivation. The analysis of the online assessment survey (n=115) revealed that successful funded learning game projects are focused on usefulness and usability. Users perceived a wider gap between successful and unsuccessful crowdfunding learning games in Learning Provision, Representation Mode, and Skill building. These enable game-based learning strategies by spelling out game rules that support learning provision in skill building, which is reflected in a detailed and in-depth narrative in a coherent representation layout. According to bivariate and multivariate analysis, among all eight dimensions, Representation mode, Interactivity, Skill building, Rules, Narrative and Learning provision are key factors that significantly associate with entrepreneurial success for the learning game development. A crowdfunding learning game TAM based perception evaluation model was developed based on perceived acceptance, usefulness and usability. This study examines the pedagogical aspects of using TAM to analyze crowdfunding learning games to help educators better use ICT to create new learning games that provide more customized, active, and flexible learning experiences, improve feedback and assessment, and increase involvement and access to game development.

Comparison of the validity, perceived usefulness, and usability of I-MeDeSA and TEMAS, two tools to evaluate alert system usability

ObjectiveTwo tools are currently available in the literature to evaluate the usability of medication alert systems, the instrument for evaluating human factors principles in medication-related decision support alerts (I-MeDeSA) and the tool for evaluating medication alerting systems (TEMAS). This study aimed to compare their convergent validity, perceived usability, usefulness, strengths, and weaknesses, as well as users’ preferences. MethodTo evaluate convergent validity, two experts mapped TEMAS’ items against I-MeDeSA’s items with respect to the usability dimensions they target. To assess perceived usability, usefulness, strengths, and weaknesses of both tools, staff with expertise in their medication alerting system were asked to use French versions of the TEMAS and I-MeDeSA. After the use of each tool, participants were asked to complete the System Usability Scale (SUS) and answer questions about the understandability and usefulness of each tool. Finally, participants were asked to name their preferred tool. Numeric scores were statistically compared. Free-text responses were analyzed using an inductive approach. ResultsForty-five participants from 10 hospitals took part in the study. In terms of convergent validity, I-MeDeSA focuses more on the usability of the graphical user interface while TEMAS considers a wider range of usability principles. Both tools have a fair level of perceived usability (I-MeDeSA’ SUS score = 61.85 and TEMAS’ SUS score = 62.87), but results highlight that revisions are necessary to both tools to improve their usability. Participants found TEMAS more useful than I-MeDeSA (t = -3.63, p =.005) and had a clear preference for TEMAS to identify problems in formative evaluation (39 of 45; 0.867, p <.001) and to compare the usability of alert systems during the procurement process (36 of 45; 0.8, p <.001). ConclusionsThe TEMAS is perceived as more useful and is preferred by participants. The I-MeDeSA seems more relevant for quick evaluations that focus on the graphical user interface. The TEMAS seems to be more suitable for in-depth usability evaluations of alert systems. Even if both tools are perceived to be equally usable, they suffer from wording, instructional, and organizational problems that hinder their use. The results of this study will be used to improve the design of I-MeDeSA and TEMAS.

THE LEGAL ROLE OF FINTECH IN FINANCIAL INCLUSION IN CHINA

The purpose of technology is not to make finance better, but to make finance serve real life better. Fintech has grown much faster in China than in the United States. In China, this success has come not from an initial technology advantage, but from integration between finance and real-life needs. This experience has important implications for understanding financial innovations, and for the development of inclusive finance. China has experienced a financial technology boom (Fintech), enabling it to be a world leader of the field. China's decision makers and authorities are promoting a digital vision the aim of which is to foster financial inclusion. Using FinTech as a catalyst for financial inclusion can be an effective and less costly solution for China. This study examines the leading role of FinTech in the efforts of the Chinese authorities towards financial accessibility in China. Using time series econometrics over the 2010 to 2020 period, we show that FinTech promotes financial inclusion. More specifically, the results show that only the access dimension can be promoted using FinTech. However, for the usage dimension, FinTech does not have a positive effect. Such findings should further encourage Chinese authorities to invest in FinTech to help remove barriers to financial inclusion.

A Two-dimensional Maintenance Service Contract Considering Availability and Maintenance Cost

In this paper, we study a two- dimensional Maintenance Service Contract (MSC) characterized by two limits (dimensions) of age and usage. It is considered that an agent offers a two-dimensional MSC by guaranteeing a certain level of equipment available to consumers. The agent needs to reduce the total maintenance cost to offer competitive MSC prices. Preventive maintenance actions (PM) are periodically carried out, and each PM action is considered to improve reliability modeled by reducing the failure rate function. Two decision variables (the PM interval (T) and the reduction in the intensity function

DAMPAK INKLUSI KEUANGAN TERHADAP RISIKO KREDIT PADA PERBANKAN DIGITAL DI INDONESIA PERIODE TAHUN 2015-2021

One of the most significant risks for banks, including digital banks, is credit risk. Bank credit risk can be influenced by a number of things, one of which is increasing financial inclusion. Then there is the prime lending rate which is used as a variable control in this study. The purpose of this study is to identify and analyze the impact of financial inclusion on credit risk in Indonesian digital banks. This study employs panel data from four Indonesian digital banks from 2015 to 2021. Panel data regression is the regression model that was used, and the hypothesis was tested with the t test, the F test, and the coefficient of determination. Financial inclusion has a positive and insignificant effect on digital bank credit risk in Indonesia on the accessibility dimension, a negative and significant effect on the usage dimension, and for prime lending rates it has a positive and insignificant effect on digital bank credit risk in Indonesia. This indicates that digital banks in Indonesia can reduce their credit risk by utilizing financial services. So that increasing financial inclusion through the use of financial services must be further improved while still paying attention to the prudence principle.

Financial Inclusion and Women-Led Small and Medium Enterprises (SMEs) Performance during Covid-19 in Chipadze, Bindura Town

Covid-19 containment measures disrupted the three financial inclusion dimensions of access, usage and quality, which affected women-led small and medium enterprises (SMEs) performance in many economies with no exception to Zimbabwe. However, the growth of small businesses depends mainly on the quality and accessibility of finance. This study examines the impact of financial inclusion on women-led SMEs performance in Bindura, Zimbabwe’s one of the mining towns during the Covid-19 era. A sample of 70 women-led businesses was selected, and data were analysed using a simple multivariate regression model. The results show a relatively low level of financial inclusion of women entrepreneurs in Bindura, having active formal bank accounts reflected by a percentage of 62.9. The study found that financial services were difficult to access, expensive and of poor quality during the Covid-19 era. Nonetheless, the study revealed significant positive effects between financial inclusion dimensions (accessibility, usage and quality) and entrepreneurial performance. Despite Covid-19 disruptions that made financial services challenging to access and of poor quality, financial inclusion was instrumental in enabling positive business performance. It is recommended that measures aimed at increasing the inclusivity of women-led businesses be fostered. These measures should be designed in a way that they make the services accessible and of good quality during the pandemic periods.

Finally, they completed the System Usability Scale questionnaire. The results revealed an impact of technophilia and age on usability dimensions. To conclude, the consideration of the ICG population in the design process of connected medical devices is discussed, particularly the age and level of technophilia.

Does Internet Use Promote Subjective Well-Being? Evidence from the Different Age Groups Based on CGSS 2017 Data.

Mobile Internet technology has developed so rapidly that the Internet has become indispensable in everyday life. There is a continuous debate about the relationship between internet use and subjective well-being. In contrast to observing whether one has Internet access, this paper focuses on three dimensions of Internet usage: frequency of use, online relationship size, and Internet proficiency. Based on the Chinese nationwide data collected in 2017, the results of the ordinary least squares regression model demonstrate that Internet use has a significant positive association with subjective well-being. In addition, this study also discovers that the effect of Internet use on the subjective well-being of individuals of different ages is heterogeneous; middle-aged individuals benefit from more frequent Internet use and larger-scale networks; the young and older adults benefit from organizing communication in groups. The results of this study can provide targeted suggestions for improving the subjective well-being of different age groups in Internet use.

The use of an artificial neural network for acoustic selections headphone filters

The article aims to examine the influence of various acoustic materials on the usable properties of headphones. Acoustic materials act as filters that modify the incident acoustic waves by attenuating specific frequency components of the acoustic signals. They can therefore be called acoustic filters because they affect the frequency response (bandwidth) of the headphones in question. Therefore, the choice of acoustic materials in headphones with a specific design can have a significant impact on their psychoacoustic properties. Calibrating your headphones is critical to ensure they don't amplify, attenuate or introduce any coloration to your frequencies. To address this problem, a dedicated test setup was designed and constructed to evaluate the frequency response of selected headphone models using seven different acoustic materials (acoustic filters). The final selection of the acoustic filter was made using an artificial neural network. The article presents the measurement methodology, and the obtained frequency response measurements were analyzed and compared.

The Relationship between Social Media Usage and Mental Well-Being among Young Adults

Background: The use of social media has grown rapidly over the past decennium and a half, however, not much research is conducted on it to identify its correlation with mental well-being and its effects. Aim: To determine the correlation between social media usage and mental well-being in young adults. Study design: Cross Sectional study. Methodology: Data was collected using convenient sampling. This study includes a sample size of 215 young adults, 108 men, and 107 women, from two universities in Lahore, Pakistan, aged between 18 -25 years. Two instruments were used in this study to measure the variables, the Social Networking Usage questionnaire, and Warwick-Edinburgh Mental Well-being Scale. Data was evaluated by using SPSS version 24. Pearson’s correlation and independent sample t-test were applied with p-value &lt; 0.05 as significant. Results: Findings indicated a significant positive relationship between all dimensions of social media usage including academic, socialization, entertainment, and information. High mean scores indicated that research participants mostly use social media for academic purposes. There was not a statistically significant relationship that could be seen between social media usage and mental well-being. Gender differences were found only related to mental well-being where men scored high as compared to women with a significance of 0.01 level. Practical Implication: Present study results raised the idea of examining other mediating or moderating factors between the connection between social media platforms usage and mental well-being. Not only the time but the content and purpose of social media should also be considered while establishing the direction of the relationship. Conclusion: It was concluded that young adults’ use of social media has not an inverse connection with mental health, and they mostly use it for academic purposes. However, men and women are different on the mental well-being scale, and men with high well-being reported for the present sample. Key words: Social Media, Correlation, Mental Well-Being, Depression and Self-Esteem.

Measurement of Financial Inclusion in India: An Integrated Approach with TOPSIS and EWM

The extent of financial inclusion among Indian states for the period has been measured and compared by constructing a composite index using an integrated methodology of TOPSIS (Technique of order preference by similarity to ideal solution) with EWM (Entropy Weighting Method). The proposed index has three broad dimensions of banking penetration, availability, and usage of banking services with an extended variable. Data for the study include: state wide bank data, demographic, geographic, and economic data, and are taken from Reserve Bank of India’s (RBI) publications. There is a general improvement in financial inclusion in India, while UT of Chandigarh and Delhi top the index, and Manipur and Nagaland bottom of the index. The southern region tops India on financial inclusion in terms of average rank. The methodology adopted in this study is not widely adopted in IFI literature. Moreover, the index has been constructed with statically assigned weight by using EWM.
