Effect of Fiber Shape on the Tribological, Mechanical, and Morphological Behaviors of Sisal Fiber-Reinforced Resin-Based Friction Materials: Helical, Undulated, and Straight Shapes
Authors: Wu Siyang , Zhao Jiale , Guo Mingzhuo , Zhuang Jian , Wu Qian
Published: September 2021

In this paper, we aim to evaluate the tribological, mechanical, and morphological performance of resin-based friction composites reinforced by sisal fibers with different shapes, namely helical, undulated, and straight shapes. The experimental results show that the shape of the sisal fibers exerts a significant effect on the impact property of the composite materials but no obvious influence on the density and hardness. The friction composite containing the helical-shaped sisal fibers exhibits the best overall tribological behaviors, with a relatively low fade (9.26%), high recovery (98.65%), and good wear resistance (2.061 × 10−7 cm3∙N−1∙m−1) compared with the other two composites containing undulated-shaped fibers and straight-shaped fibers. The impact fracture surfaces and worn surfaces of the composite materials were inspected by scanning electron microscopy, and we demonstrate that adding helical-shaped sisal fibers into the polymer composites provides an enhanced fiber–matrix interface adhesion condition and reduces the extent of fiber debonding and pullout, effectively facilitating the presence of more secondary plateaus on the friction surface, which are responsible for the enhanced tribological and mechanical properties. The outcome of this study reveals that sisal fibers with a helical shape could be a promising candidate as a reinforcement material for resin-based brake friction composite applications.

Published: September 2021

Resistance spot welding (RSW) is a common joining technique in the production of car bodies in white for example, because of its high degree of automation, its short process time, and its reliability. While different steel grades and even dissimilar metals can be joined with this method, the current paper focuses on similar joints of galvanized advanced high strength steel (AHSS), namely dual phase steel with a yield strength of 1200 MPa and high ductility (DP1200HD). This material offers potential for light-weight design. The current work presents a multi-physical finite element (FE) model of the RSW process which gives insights into the local loading and material state, and which forms the basis for future investigations of the local risk of liquid metal assisted cracking and the effect of different process parameters on this risk. The model covers the evolution of the electrical, thermal, mechanical, and metallurgical fields during the complete spot welding process. Phase transformations like base material to austenite and further to steel melt during heating and all relevant transformations while cooling are considered. The model was fully parametrized based on lab scale material testing, accompanying model-based parameter determination, and literature data, and was validated against a large variety of optically inspected burst opened spot welds and micrographs of the welds.

Published: September 2021

This paper describes methods, procedures, and results of cyclic loading tensile tests of a PBO FRCM composite. The main objective of the research is the evaluation of the effect of low- and high-cycle fatigue on the composite tensile properties, namely the tensile strength, ultimate tensile strain, and slope of the stress–strain curve. To this end, low- and high-cycle fatigue tests and post-fatigue tests were performed to study the composite behavior when subjected to cyclic loading and after being subjected to a different number of cycles. The results showed that the mean stress and amplitude of fatigue cycles affect the specimen behavior and mode of failure. In high-cycle fatigue tests, failure occurred due to progressive fiber filaments rupture. In low-cycle fatigue, the stress–strain response and failure mode were similar to those observed in quasi-static tensile tests. The results obtained provide important information on the fatigue behavior of PBO FRCM coupons, showing the need for further studies to better understand the behavior of existing concrete and masonry members strengthened with FRCM composites and subjected to cyclic loading.

Published: September 2021

In view of the problems of traditional repair materials for anchorage concrete of expansion joints, such as ease of damage and long maintenance cycles, the design of polyurethane concrete was optimized in this article, which could be used for rapid repair of concrete in anchorage zone of expansion joints. A new type of carbon fiber grid–polyurethane concrete system was designed, which makes the carbon fiber grid have an excellent synergistic effect with the quick-hardening and high-strength polyurethane concrete, and improved the flexural bearing capacity of the polyurethane concrete. Through the four-point bending test, the influence of the parameters such as the number of grid layers, grid width, and grid density on the flexural bearing capacity of polyurethane concrete beams was tested. The optimum preparation process parameters of carbon fiber grid were obtained to improve the flexural performance of polyurethane concrete. Compared with the Normal specimen, C-80-1’s average flexural strength increased by 47.7%, the failure strain along the beam height increased by 431.1%, and the failure strain at the bottom of the beam increased by 68.9%. The best width of the carbon fiber grid was 80 mm, and the best number of reinforcement layers was one layer. The test results show that the carbon fiber grid could improve the flexural bearing capacity of polyurethane concrete. The carbon fiber grid–polyurethane concrete system provides a new idea for rapid repair of the anchorage zone of bridge expansion joints, and solves the problems such as ease of damage and long maintenance cycles of traditional repair materials, which can be widely used in the future.

The paper presents a comparative study of the activity of magnetite (Fe3O4) and copper and cobalt ferrites with the structure of a cubic spinel synthesized by combustion of glycine-nitrate precursors in the reactions of ammonia borane (NH3BH3) hydrolysis and hydrothermolysis. It was shown that the use of copper ferrite in the studied reactions of NH3BH3 dehydrogenation has the advantages of a high catalytic activity and the absence of an induction period in the H2 generation curve due to the activating action of copper on the reduction of iron. Two methods have been proposed to improve catalytic activity of Fe3O4-based systems: (1) replacement of a portion of Fe2+ cations in the spinel by active cations including Cu2+ and (2) preparation of highly dispersed multiphase oxide systems, involving oxide of copper.

Authors: Yoon Hyun-Sub , Yang Keun-Hyeok , Lee Kwang-Myong , Kwon Seung-Jun
Published: September 2021

Since a concrete structure exposed to a sulfate environment is subject to surface ion ingress that yields cracking due to concrete swelling, its service life evaluation with an engineering modeling is very important. In this paper, cementitious repair materials containing bacteria, Rhodobacter capsulatus, and porous spores for immobilization were developed, and the service life of RC (Reinforced Concrete) structures with a developed bacteria-coating was evaluated through deterministic and probabilistic methods. Design parameters such protective coating thickness, diffusion coefficient, surface roughness, and exterior sulfate ion concentration were considered, and the service life was evaluated with the changing mean and coefficient of variation (COV) of each factor. From service life evaluation, more conservative results were evaluated with the probabilistic method than the deterministic method, and as a result of the analysis, coating thickness and surface roughness were derived as key design parameters for ensuring service life. In an environment exposed to an exterior sulfate concentration of 200 ppm, using the deterministic method, the service life was 17.3 years without repair, 19.7 years with normal repair mortar, and 29.6 years with the application of bacteria-coating. Additionally, when the probabilistic method is applied in the same environment, the service life was changed to 9.2–16.0 years, 10.5–18.2 years, and 15.4–27.4 years, respectively, depending on the variation of design parameters. The developed bacteria-coating technique showed a 1.47–1.50 times higher service life than the application of normal repair mortar, and the effect was much improved when it had a low COV of around 0.1.
Transient Electro-Thermal Coupled Modeling of Three-Phase Power MOSFET Inverter during Load Cycles
Authors: Cheng Hsien-Chie , Lin Siang-Yu , Liu Yan-Cheng
Published: September 2021

This study introduces an effective and efficient dynamic electro-thermal coupling analysis (ETCA) approach to explore the electro-thermal behavior of a three-phase power metal–oxide–semiconductor field-effect transistor (MOSFET) inverter for brushless direct current motor drive under natural and forced convection during a six-step operation. This coupling analysis integrates three-dimensional electromagnetic simulation for parasitic parameter extraction, simplified equivalent circuit simulation for power loss calculation, and a compact Foster thermal network model for junction temperature prediction, constructed through parametric transient computational fluid dynamics (CFD) thermal analysis. In the proposed ETCA approach, the interactions between the junction temperature and the power losses (conduction and switching losses) and between the parasitics and the switching transients and power losses are all accounted for. The proposed Foster thermal network model and ETCA approach are validated with the CFD thermal analysis and the standard ETCA approach, respectively. The analysis results demonstrate how the proposed models can be used as an effective and efficient means of analysis to characterize the system-level electro-thermal performance of a three-phase bridge inverter.

Authors: Sofronova Daniela , Angelova Radostina A. , Sofronov Yavor
Published: September 2021

An e-textile mat with capacitive textile sensors was designed and manufactured to monitor body position and prevent decubitus ulcers in the case of bedridden people. The sensors were incorporated through a process of machine embroidery with electrically conductive threads. A new production method for the conductive threads is still expected to be developed, resulting in good conductive properties, high wear resistance and durability. Samples of five variants of motifs without cross-stitching were studied, and the capacity and electrical resistance were determined experimentally. A prototype of the e-textile mat was made with a motif showing the best ratio between the inserted thread and the measured capacity. A hardware solution and a software application for collecting, processing and visualising the received information were developed. Tests were performed in real conditions, which clearly showed that the designed e-textile mat could be successfully applied for non-invasive and continuous control of the position of the human body in a supine position to prevent decubitus ulcers.

Published: September 2021

The use of bioactive glasses in dentistry, reconstructive surgery, and in the treatment of infections can be considered broadly beneficial based on the emerging literature about the potential bioactivity and biocompatibility of these materials, particularly with reference to Bioglass® 45S5, BonAlive® and 19-93B3 bioactive glasses. Several investigations have been performed (i) to obtain bioactive glasses in different forms, such as bulk materials, powders, composites, and porous scaffolds and (ii) to investigate their possible applications in the biomedical field. Although in vivo studies in animals provide us with an initial insight into the biological performance of these systems and represent an unavoidable phase to be performed before clinical trials, only clinical studies can demonstrate the behavior of these materials in the complex physiological human environment. This paper aims to carefully review the main published investigations dealing with clinical trials in order to better understand the performance of bioactive glasses, evaluate challenges, and provide an essential source of information for the tailoring of their design in future applications. Finally, the paper highlights the need for further research and for specific studies intended to assess the effect of some specific dissolution products from bioactive glasses, focusing on their osteogenic and angiogenic potential.
Constraint-Following Servo Control for the Trajectory Tracking of Manipulator with Flexible Joints and Mismatched Uncertainty
Authors: Dong Fangfang , Yu Bin , Zhao Xiaomin , Chen Shan , Liu Haijun
Published: September 2021

Trajectory tracking is a common application method for manipulators. However, the tracking performance is hard to improve if the manipulators contain flexible joints and mismatched uncertainty, especially when the trajectory is nonholonomic. On the basis of the Udwadia–Kalaba Fundamental Equation (UKFE), the prescribed position or velocity trajectories are creatively transformed into second-order standard differential form. The constraint force generated by the trajectories is obtained in closed form with the help of UKFE. Then, a high-order fractional type robust control with an embedded fictitious signal is proposed to achieve practical stability of the system, even if the mismatched uncertainty exists. Only the bound of uncertainty is indispensable, rather than the exact information. A leakage type of adaptive law is proposed to estimate such bound. By introducing a dead-zone, the control will be simplified when the specific parameter enters a certain area. Validity of the proposed controller is verified by numerical simulation with two-link flexible joint manipulator.

Published: September 2021

The biological water oxidation takes place in Photosystem II (PSII), a multi-subunit protein located in thylakoid membranes of higher plant chloroplasts and cyanobacteria. The catalytic site of PSII is a Mn4Ca cluster and is known as the oxygen evolving complex (OEC) of PSII. Two tyrosine residues D1-Tyr161 (YZ) and D2-Tyr160 (YD) are symmetrically placed in the two core subunits D1 and D2 and participate in proton coupled electron transfer reactions. YZ of PSII is near the OEC and mediates electron coupled proton transfer from Mn4Ca to the photooxidizable chlorophyll species P680+. YD does not directly interact with OEC, but is crucial for modulating the various S oxidation states of the OEC. In PSII from higher plants the environment of YD• radical has been extensively characterized only in spinach (Spinacia oleracea) Mn-depleted non functional PSII membranes. Here, we present a 2D-HYSCORE investigation in functional PSII of spinach to determine the electronic structure of YD• radical. The hyperfine couplings of the protons that interact with the YD• radical are determined and the relevant assignment is provided. A discussion on the similarities and differences between the present results and the results from studies performed in non functional PSII membranes from higher plants and PSII preparations from other organisms is given.

Annette Kolbs Die Schaukel und das subversive Potenzial von Literatur
Authors: Lenger Charlotte
Published: September 2021

Der Beitrag stellt eine Untersuchung des Romans Die Schaukel (1934) von Annette Kolb hinsichtlich des emanzipatorischen Potenzials dar, Verschränkungen sozialer Ungleichheit subversiv zu unterlaufen. Es wird dabei angenommen, dass Literatur als kulturelles Produkt gesellschaftliche Strukturen sichtbar macht, reproduziert, aber auch infrage stellen kann. Die Analyse narratologischer Darstellungsweisen hinsichtlich der Konstruktion narrativer Identitäten deckt unter Einbezug intersektionaler Überlegungen subversive Strategien bezüglich gegebener Machtund Herrschaftsstrukturen auf. Es wird gezeigt, dass unteranderem anhand der beiden Figuren Herr und Frau Lautenschlag eine binär strukturierte Opposition von Männlichkeit und Weiblichkeit und eine damit einhergehende Verschränkung von Ungleichheit bezüglich der identitären Strukturkategorien Geschlecht und Ökonomie durch die Verortung innerhalb von geschlechtsspezifischen Räumen sowie durch erzähltextspezifische Zeitdarstellung erwirkt und gleichzeitig durch Ironie unterlaufen wird. Eine Bezugnahme auf gesellschaftliche Strukturen des extraliterarischen Raumes wird durch die Erzählinstanz als ‚engaging narrator‘ hergestellt, welche die Identitäten der bayrischkatholischen Familie Lautenschlag und der preußisch-protestantischen Familie von Zwinger narrativ und affirmativ als sich gegenüberstehende Oppositionen innerhalb des Diskurses der deutschen Nationalgründung konstruiert. Diese Konstruktion äußert sich als geprägt von einer Verwobenheit der Kategorien Nation, Religion, Ökonomie und Klasse. Deutlich wird durch die Untersuchung, dass sich die Familie Lautenschlag besonders durch ihr kulturelles Kapital von den von Zwingers und ihrem Wertesystem emanzipiert. Der Übermut der Kinder Lautenschlag zeigt sich als Freifahrtschein gegenüber jeglichen Konventionen. Die allegorische Darstellung der Tochter der Lautenschlags Hespera im Sinne des ‚Friedens‘ zwischen unterschiedlichen nationalen Identitäten und konfessioneller Zugehörigkeit stellt eine sich der eindeutigen Zuordnung verweigernde Figur dar. Ebenso vermittelt die narrative und besonders von Ironie disponierte Konstruktion der Tochter Mathias sowohl eine geschlechtliche Ambiguität als auch einen Widerstand gegenüber sozialer Assimilation.

Freshwaters are among the most threatened ecosystems, particularly in North Africa where urbanization and climate change are exerting an important pressure on aquatic fauna. Long-term investigation of macroinvertebrates is one of the best ways of tracking and understanding the influence of environmental and anthropogenic pressures on community dynamics. In this study, we focus on determining the community structure and diversity of benthic macroinvertebrates as well as the state of aquatic physicochemical parameters in the Bouhamdane Stream, near the outlet of Bouhamdane dam, Seybouse watershed, north-eastern Algeria. We carried out a bi-monthly sampling of macroinvertebrates and nine water physicochemical parameters from September 2017 to July 2018 at three sites. Results show that the collected macroinvertebrates (6756 individuals) belong to 15 families and 12 orders. The abundance of the macrofauna consisted of 88.19% crustaceans, 7.74% insects, 3.7% molluscs and 0.16% annelids. Physicochemical analyzes (depth, turbidity, pH, dissolved O2, temperature, salinity, and conductivity) showed variability among sites. The families of Gammaridae and Baetidae were the most frequent and the most abundant on all the stations. The results indicate that aquatic macroinvertebrates constitute good indicators of the biological quality of water. This study shows that even with the occurrence of regular dam water discharge, the macroinvertebrate community is still able to persist either through adaptation to high water velocity or high colonization rate.

Various studies have shown that alongside the social and psychological factors, the design and architectural appearance of a nursing home can have a great impact on the safety of the elderly residing in such place. However, the deficiency of information on how these factors can be operationalized in practice is not provided for architects and interior designers. Therefore, this study is aimed to inspect which architectural factors contribute to maximize the elderly patient safety and how these can be implemented in the architectural and policy guidelines. The objective of this study is also to get better understanding of potential opportunities and challenges associated with interior design that may promote well-being, aging in place, and independent living of the senior citizens. A holistic understanding of which factors influence the maximum safety could lead to improvements of the elderly nursing home designs and the residents. In order to take precautions, we must first understand the unique risks faced by the seniors at home.

Published: September 2021

This article is a preliminary study using systematic analysis of literature review for politics and election studies in Terengganu. Based on Table 1, the party that ruled Terengganu had changed thrice from 1959 to 2018. This started from the first general election until the 14th general election. At the beginning of 1959, Terengganu is governed by the Malaysian Islamic Party (PAS; Parti Islam Se-Malaysia). Nevertheless, the state ruling was taken over by Perikatan or BN in 1964 to 1995 and was seized by PAS in 1999. In 2004, BN managed to occupy the government seat once more, but it lasted for only 15 years compared to the years before because, in 2018, PAS managed to win the hearts of the Terengganu people to rule the state back again. The purpose of this study is to identify the number of studies and research themes in the studies on politics and election in Terengganu. Apart from that, the voting pattern in Terengganu from 1959 to 2018 is also included as the basis of knowledge about the election in Terengganu.

Published: September 2021

The novel Coronavirus disease (COVID-19) first appeared in December 2019 in Wuhan, Hubei Province China before emerging in neighbouring countries in early 2020. The World Health Organization (WHO) declared COVID-19 a pandemic when the spreading of the virus started accelerating in many parts of the world and killing thousands of people. As of 22nd May 2021, there were more than 166 million confirmed cases with more than 147 million recovered and nearly 3.5 million deaths (Worldometers, n.d.). According to the WHO (2020) and Centers for Disease Control and Prevention (2020), the virus easily spreads through coughing and sneezing. Therefore, many countries implemented social distancing between individuals and various other restriction orders or recommendations (e.g., stay-at-home policies, closure of non-essential businesses) to help curb virus spread. How governments in each country reacted to control the spread of the virus appeared crucial to mitigate public health and economic impacts.

"Green Supply Chain Management and Logistics Performance in the Construction Industry."
Authors: Bikissa-Macongue Marie Brinda , Chinomona Dr Elizabeth
Published: September 2021

Due to their prominent position in the market, construction companies are increasingly required to control and minimise the internal and external environmental impact of their day-to-day activities. To achieve this, all over the world, construction companies have gradually adopted different environmentally friendly practices promoting the preservation of the environment. Generally, many of these practices are carried out in the area of green supply chain management (GSCM) and logistics performance where there is a great potential to reduce the rate of pollution generated. Therefore, the purpose of the study is to identify effective GSCM factors necessary to develop a successful framework that could guide the managers for improving the environmental performance of their companies. For this study, a qualitative approach was adopted. A content analysis was carried out using different types of documents like journals, policies, and published materials. The study suggests that by adopting GSCM and improving their logistics performance, construction companies will be able to improve their environmental performance. In addition, the study implied that construction companies that comply with the different laws and regulations established, development and implement a green information system as well as a good reverse logistics system are more likely to reduce the environmental impact of their activities, while optimising their economic viability. Therefore, it is recommended that construction companies keep giving more attention to GSCM and logistics performance as it is the most innovative means by which they can get cost efficiency and environmental responsibility simultaneously.

Published: September 2021

A rising number of cases involving ethical misconduct within firms have of late received considerable attention in Malaysia. Despite the country's declaring having a strong corporate governance policy, strengthened through the Code of Ethics for Company Directors and Malaysia Code of Corporate Governance, the unethical practices and lack of integrity within firms remain an issue. PricewaterhouseCoopers (PwC) Malaysia conducted a survey in 2018, it was found that 41 percent of Malaysian registered companies were guilty of committing some forms of economic crimes, specifically business misconduct, asset misappropriation, bribery, and corruption. They added, the actual number may be higher due to many cases of ethical misconduct that typically go unreported. Furthermore, crimes of ethical misconduct in Malaysia have also increased by 28 percent in the last two years. It was revealed taht corporate culture was the most influential element in helping detect early warning signs of ethical misconduct within a firm. A KPMG 2019 report published in the subsequent year also suggested that an unhinged desire for a wealthy lifestyle acts as a prime motivation behind many of the unethical behaviors discovered. Thus, in the light of the increasingly worsening situation of ethical misconduct in Malaysian firms, the need to explore these corporate ethical issues has never become more crucial and appropriate. The ubiquitous nature of the issue has subsequently jeopardized the financial reporting quality of Malaysia's firms.

Exploratory Study of Cultural Impact on Management Practices and Organizational Behaviour in Christian-based Universities on Java Island
Authors: Widjaja Jahja Hamdani , Kuslina Boedi Hartadi
Published: September 2021

Universities, especially in the United States, have developed from an organization that aims to educate someone with a higher knowledge and spiritual awareness of God which is at the same time related to the interests and goodness of society (Murphy, 2005) into an organization that considers profit as a measure of success (Bridgman, 2007). Therefore, the application of a business management system to manage a university to produce high performance is important and this is known as a university enterprise or entrepreneurial university (Sandgren, 2012). Culture is central to management because it influences various things in the organization such as leadership, organizational management, adaptability, performance, and others that will influence in the long run (Paksoy, Genc, and Kilic, 2015). In the context of a Christian-based university in Indonesia, the understanding of cultural meanings and the process of cultural formation is an interesting topic to study. Even though it has a fundamental similarity, namely Cristianity, it appears that there are different management practices and behaviours in 'A' rank accreditation Christian university on Java island. The process of cultural formation in Christian universities and its elaboration in management practices and patterns of organizational behaviour are things that are rarely studied. The purpose of this study is to explain the process of organizational culture forming in Christian-based universities on Java island. The description of this process is expected to inspire how to build an organizational culture in a university.

This paper discusses how Kemahiran Insaniah (KI) (softs kills) for teachers are constructed by accepting the combination of the Standard Guru Malaysia (SGM) 2.0 and Sistem Sahsiah Bersepadu 4K (SSB4K) or Integrated Personality System Theory. The main objective of the study was to highlight the contents of the SGM2.0 and SSB4K in order to propose teachers with relevant soft skills for transition into various education landscapes. The realisation of this objective can be met if most of the qualities of the features drawn from the SGM 2.0 together with SSB4K offer relevant and responsive curricula in line with current teaching practices. In this article, the researchers address the concern of experts’ views on the way experts see themselves as professionals teaching and how they compose their identities. Three data themes, expert authority, commitment to the profession, and multitasking are theorised from a symbolic interactionist (SI) framework, using constructs such as situational, social, and personal identity. This study is part of a larger research project involving the development of the understanding of the soft skills of teachers and broader teacher standards issues within Malaysian context. This study aimed to outline the current soft skills of teachers. The data were analyzed by qualitative content analysis. Two kinds of perspectives are described: the media perspective by illustrating what kind of descriptions, evaluations, and requirements of SGM2.0 and SSB4K is established in framing soft skills for teachers and the experts’ perspective by reporting the experiences and evaluations of themselves. These two perspectives are described and interpreted. The findings show that soft skills are a crucial part of the competence of teachers. Four main categories of soft skill competencies were oral communication skills, media digital skills, thinking skills, and leadership skills.

This study aims to identify the level of transformational leadership of principals and the level of school effectiveness in TS25 schools in Gua Musang District, Kelantan. In addition, this study also seeks to look at the relationship between the two variables involved, transformational leadership and school effectiveness. This quantitative study by cross-sectional survey method used two types of instruments, namely the Transformational leadership instrument by Leithwood and Jantzi (1999) and the school effectiveness instrument adapted from the study of Lazaridou and Iordanidis (2011. The sampling of the study involved four TS25 secondary schools with a total of 162 teachers. The findings of the study showed that the level of transformational leadership of principals and the level of school effectiveness was at a high level, with values (M = 4.17, SP = .604) and (M = 4.19, SP = .613) respectively. Further, correlation analysis showed that there was a very strong and significant relationship (r = .89, p <.01) between the two variables involved, namely transformational leadership and school effectiveness. It is hoped that the findings of this study can be used as a guide by the parties involved, especially the Ministry of Education Malaysia in strengthening the characteristics of high-performing leadership among school administrators towards improving school effectiveness through professionalism programs.

The success of the Malaysian Education Blueprint 2015-2025 could be achieved by the effective practices of e-learning. E-learning is not just an option today but has become a necessity when the pandemic covid-19 strikes the world. Therefore, this study aims to validate an instrument of an e-learning practice among student teachers in a public university. 139 respondents are randomly selected from undergraduate students from one of the public universities in Malaysia. In order to measure the suitability of each item and validate the instrument, exploratory factor analysis (EFA) is used. The findings of the study show that all load factor values exceed 0.5 so all items are accepted for real study. This instrument has a high degree of validity and reliability to determine the e-learning practices among university students.

Soft skills are non-academic competencies that complement a student's academic achievement to face the world of work in the future. This study aims to identify ways of implementing soft skills and the kind of soft skills emphasized in the teaching and learning of the Malay language among secondary school students in nine selected schools in Kedah, Penang, and Perak. The study involved focus group interviews and individual interviews consisted of 119 students and 26 Malay language teachers. The findings show that soft skills apply directly and indirectly through various learning activities in Malay Language subjects. Respondents from normal schools received less exposure to soft skills compared to respondents from high-performing schools (HPS). Among the soft skills identified in this study are teamwork skills, self-confidence, communication, critical thinking, leadership, influencing skills, critical and creative thinking skills (CCTS), and problem-solving skills. Communication skills and teamwork skills were among the most detected soft skills in the three high-performing schools involved in this study. Meanwhile, the activities carried out to apply soft skills are group discussions, presentations, acting, poetry recitation, storytelling, public speaking, forums, and question and answer. Although this study is not comprehensive in terms of the number of schools and respondents, the findings of this study are important to explain the real scenario of the level of mastery and integration of soft skills, especially in the nine cases of this study.

The Adoption of programming education has become a global trend. In Japan, the Japan Revitalization Strategy 2016, announced by the Headquarters for Japan's Economic Revitalization in 2016, set forth the aim of making programming education compulsory in primary and secondary education. The purpose of this is to cultivate basic logical thinking skills through programming education, as part of efforts to develop and secure human resources for sparking economic growth. On the other hand, it will likely be necessary to review previously existing programming education in ICT human resources development courses at various types of schools. In the programming education for beginners that we are implementing at a college of technology, there is a considerable percentage of students who feel they are not up to programming. Thus, this study proposes "bidirectional transcription learning" for beginner programmers as an educational method to help strengthen programming education. It focuses on the process of converting a natural language to a programming language in the final stage of unplugged to code writing. Based on experience, transcription learning is regarded as effective for mastering programming, but we have conducted a trial to further improve efficiency and deepen understanding, and here we provide an overview and report on our results.

Customer satisfaction is an important issue in various sectors including in educational institutions. The needs and requirements of students and lecturers as customers of an institution must be met by the management to ensure quality services are offered. The performance of an organization is measured by customer satisfaction with their needs. Customer satisfaction issues do not only occur in Malaysia but also abroad. Complaints and grievances about the facilities and services provided were the cause of this study. Therefore, this study was conducted to determine the level of satisfaction of students and lecturers on the services and facilities provided at IPG Kampus Dato’ Razali Ismail. The respondents of the study consisted of students and lecturers selected by stratified random sampling. Data were collected based on a questionnaire distributed online and involved seven dimensions. Descriptive analysis was performed using SPSS 26 for windows and then fuzzy logic analysis using Matlab R2020b for windows. Fuzzy logic uses linguistic variables given degrees of membership. A fuzzy inference system using the Fuzzy Mamdani model was used to process the data. Hence, to get the output there are four levels that need to be done namely blurring, ordering, inference and defuzzification. The findings of this study enable management to maintain existing performance and make continuous improvements over time to ensure service quality and customer satisfaction.
