Published: March 2024

Online learning has gained prominence due to numerous success stories, becoming a vital component and instrument for reforming classrooms in higher vocational education. However, the physical detachment inherent in online self-directed learning has raised concerns about student disengagement and isolation during the learning process. Social presence theory provides a unique perspective, methods, and tools for researching online learning. This paper presents a comprehensive analysis of the existing literature, with a focus on social presence, learning satisfaction, and persistence. The results reveal the intricate impact of social presence on learning satisfaction and persistence in online learning environments. A systematic literature review (SLR) was conducted to uncover research findings from May 2013 to June 2023. The selected articles underwent a thorough assessment, and duplicates were removed. The updated criteria for conducting systematic reviews and meta-analyses were used for the literature review. The research team critically analysed, finalised, and deliberated on the significance of the SLR. Out of the 220 papers initially considered, 28 met the specific criteria for adjustment and inclusion/exclusion.

Published: March 2024

The presence of an alternative framework in the students’ minds acts as the main hindrance to students exhibiting profound understanding of scientific concepts, which in turn promotes the application of scientific knowledge to solve daily life context problems. This research is done in two phases. In the first phase, the research aims to identify the alternative framework among students on the concept of electrochemistry, and in the second phase, it develops an instructional module for secondary school students on the concept of electrochemistry by using the five-phase Needham constructivism model approach to overcome the alternative framework that exists in the students’ minds. In this paper, however, only the findings of the first phase are reported. The instrument used for this study is the electrochemistry test developed based on previous research and validated by experts. This paper and pencil test is used in the first phase of the research as a data collection tool. This research adapted a quantitative research design. The data from the electrochemistry test is analyzed using statistical packages for social sciences (SPSS) 20.0 to get the descriptive data as findings of the first phase of the study. The findings of the first phase of this study indicate that the conceptualization level of students in electrochemistry is poor. Multiple alternative frameworks among students were identified from the analysis of the students’ responses. This study contributed to existing literature by identifying the alternative frameworks present precisely in electrochemistry. The study recommends incorporating mobile technologies in the data collection process and in developing online instructional modules to be more accessible to educators throughout the country and to steer the chemistry education world to a higher level in the Malaysian education system. Enlightening the alternative framework existent in the students’ knowledge schemata immensely facilitates educators worldwide in planning their instructional approach in the classroom for this specific scientific concept.

Published: March 2024

Due to the recent developments in design optimization techniques and advanced construction technologies, uses of castellated beams have become very popular. Castellated beams because of their high strength to weight ratio and low maintenance and painting cost have effectively replaced built-up girders in light to medium constructions for medium to long spans. Longitudinal cuts in the form of openings along the web of castellated beams also results in stronger and stiffer beams than their parent beams without any increase in the self-weight. In this study, attempts are made to compare the behavior of castellated beams with their parent beams. Studies on effect of different web openings on deflection are carried out using finite element analysis.

Digital light processing (DLP) technology has been developed based on stereolithography (SLA) 3D-printing principle. The biodegradable and low-cost polylactic-acid (PLA) has so far been used as polymeric material for photopolymer resin in SLA and DLP. To achieve functional SLA-processed product, the properties of such PLA has been improved, with the aim to make it flame retardant, less viscous, and having light transmittance characteristics. In this study, the liquid raw PLA photopolymer was changed by adding different contents of Ammonium Phosphate (APP), melamine cyanurate (MCA), Aluminum Tri-hydroxide (Al2O3) and Nano-silicon dioxide (SiO2) additives. The solid PLA nanocomposite specimens were printed by using DLP device according to the standard geometry for burning test UL-94 to evaluate its flame-retardant property. In addition, the printing product and residue after burning test was analyzed for their morphological characteristic by using SEM. The results showed that the low weight fraction of MCA showed excellent performance. PLA/MCA successfully kept green body form until the sintering temperature of stainless steel was achieved. It can become a reference for application DLP 3D printing products in the casting and sintering process.

Links Between Maternal Emotion Socialization Goals and Practices in an Urban Indian Context
Authors: Kathuria Tripti , Kapadia Shagufa , Friedlmeier Wolfgang
Published: March 2024

Socialization goals and practices are shifting and changing in countries like India due to modernization, particularly in urban context. Given the shift, mothers may endorse balanced socialization goals over traditional relational goals and that may influence their emotion regulation behavior with the toddlers. This paper aims to test whether mothers’ emotion socialization practices toward their toddlers differ with reference to their socialization goals for both positive and negative socially disengaging and engaging emotions. Fifty mothers of toddlers (M = 25 months) from Vadodara, India, participated in the study. They answered the Emotion Socialization Goals Questionnaire (Chan et al., 2006) and were interviewed about their emotion regulation practices. Results indicated that the majority (58%) of Indian mothers showed clear preference for endorsing balanced goals. As expected, mothers with relational goals endorsed more non-supportive strategies like training, especially for negative socially disengaging emotions. No differences occurred for positive emotions. The findings are discussed with respect to the various emotion competence models that are present in the Indian cultural context.
Issue of Multicultural People in Globalizing Japan: (Cultural) Identity, Mental Health and “Ibasho”
Authors: Suzuki Kazuyo , Ishibashi Michiko , Suzuki Yumi , Nitta Fumiteru
Published: March 2024

The number of multicultural people has increased over many years with the globalization of the world economy. Japan is no exception. Ibasho is a Japanese unique concept and means one’s place where one feels secure, comfortable, and accepted. There are very few studies on ibasho among people with multicultural backgrounds. Suzuki (2018) refers to relationships among identity/cultural identity formation, mental health (including subjective well-being) and ibasho. In this paper, we examined the relationship among mental health, identity and ibasho with a focus on ibasho in the case of two groups of people with multicultural backgrounds: International students (N = 105) living in Japan, from 30 countries (Study 1) and Japanese-Indonesian young people (N = 10) living in Indonesia (Study 2). In Study 1, a questionnaire survey and interviews were conducted, and in Study 2, multiple interviews were carried out. In both studies, the analysis was mainly qualitative in nature. The results showed that there was the relationship among ibasho, mental health, and (cultural) identity, and creating ibasho was very useful to support for cultural identity formation of multicultural people as well as to maintain their mental health.

Published: March 2024

Introduction: Tele-ergonomics is a telehealth service that shows great potential use given people’s growing reliance on the internet, highlighted during the COVID-19 pandemic. Studies have been conducted internationally regarding the implementation, feasibility, and efficiency of tele-ergonomics. As perceptions of physical therapists regarding this technology have not been explored in the Philippines, the objective of the study is to explore their perceptions on the practice.

Methods: The study utilized a phenomenological design involving 10 licensed Filipino physical therapists selected through purposive sampling. Key informant interviews were conducted via Google Meet for data collection. The interview questions derived from Rosenstock’s Health Belief Model were self-made, semi-structured, and validated by two methodological experts. All interviews were audio-recorded, transcribed verbatim, coded, and analyzed for the emergence of patterns by thematic content analysis through manual coding using Google Sheets to group themes and subthemes. The data was consolidated into an in-depth analysis and was further proofread by all researchers.

Results: Thematic content analysis yielded a total of 52 codes, further categorized into four major themes, namely: (1) emergence of tele-ergonomics; (2) practices of tele-ergonomics; (3) its outcomes; and (4) recommendations for the future of the practice.

Discussion: The study found that tele-ergonomics is necessary with the rise of digitalization and provided recommendations for the continuity of tele-ergonomics. It highlighted the need for proper training to refine the skills of physical therapists. As digitalization opens up new avenues of learning and delivery of services, it is important to establish comprehensive training that incorporates a more in-depth assessment of digital aspects. Hence, readiness is contingent upon proper training. The data further emphasizes one’s control over their motivation, behavior, and efficacy in providing the services.
DIAGNOSIS-RELATED BELIEFS OF FILIPINOS WITH CHRONIC BACK PAIN: A QUALITATIVE STUDY
Authors: Catacutan Jerell , Leaver Andrew , Bandong Aila Nica , Gorgon Edward , Gelisanga Maribeth Anne
Published: March 2024

Introduction: Patient education is needed in the effective management of chronic low back pain (CLBP). To be effective, education resources need to target key beliefs and attitudes around back pain. This study aimed to explore the diagnosis-related beliefs of Filipinos who are seeking treatment for CLBP. The specific objective is to explore patients’ understanding of their diagnoses and their beliefs about how health care professionals might help them.

Methods: We used a qualitative research design with an interpretive description approach. We conducted a semi-structured phone interview strategy, using piloted questions. Patients’ understanding of diagnosis and their beliefs was explored using a thematic analysis. We had seven adult participants with non-specific CLBP of at least three months duration attending physiotherapy sessions at the Department of Rehabilitation Medicine outpatient clinic of a tertiary teaching hospital in Metro Manila. To the researchers’ judgement, these selected participants could provide information-rich data, communicate experiences and opinions in an articulate (self-reported ability to understand, speak and write in Filipino), expressive and reflective manner.

Results: The analysis of data identified four themes with subthemes related to information that clinicians need to understand and consider when developing effective educational resources for patients with CLBP: (1) Beliefs about causes of back pain; (2) Experience of Back Pain; (3) Actions & Responses to Back Pain; and (4) What might help.

Discussion: The overall finding of this study is that many of the beliefs and experiences in this group of Filipinos with back pain are similar to those from other populations and some of the findings were somewhat unique or at the least nuanced to Filipinos with back pain. One of the themes that appeared more unique to these participants were the beliefs about cold and damp weather causing back pain. These beliefs appear to inform the choices of treatment – hot pack, liniments, and avoidance behavior described by the participants in relation to cold weather. Another unique theme that emerged in this study is the role of faith and religion in managing back pain. Participants from this study appeared to portray prayer as a potential form of therapy to manage back pain rather than as a form of coping mechanism. When developing education resources for patients with CLBP, clinicians may consider integrating information that matches the beliefs and understanding of Filipinos with CLBP to make the education resources more suitable, relevant, and fit to the Filipino context.

Authors: Rahaman S.M.
Published: March 2024

"Conservation agriculture (CA) evolved as a practice in response to concerns of sustainability of agriculture globally and also is a viable solution for Sustainable Intensification. The study was attempted to examine the profitability of CASI technology vis-à-vis traditional cultivation practices especially for direct Seeded Rice (DSR) and Zero Till (ZT) wheat. Primary data was collected from 120 sample farmers following a multi stage sampling technique. It was observed that 40.83 per cent farmers adopted either of the CASI technology. The level of adoption was found lowest among marginal and small farmers (18.87%) whereas most of the medium farmers (94.44%) and almost half of the semi medium farmers (44.90%) tried CASI at least in some portion of their field. CASI technology was mainly followed in cereal crops (paddy, wheat and maize). The grain and straw productivity with the adoption of CASI raised the gross income by 14.48, 18.75 and 19.70 per cent in rice, wheat and maize, respectively. CASI adopters on an average earned 53 paisa, 55 paisa and 1.34 rupee more than the net return obtained by conventional farmers over each rupee invested paddy, wheat and maize respectively. This was primarily due to the reduction in explicit cost items. Adoption of conservation agriculture technology can surely reduce the farmer’s costs of cultivation and also increase the farmer’s net income and thereby results in the betterment of standards of living."

Authors: Kishore N.T. Krishna
Published: March 2024

"Increased start-up activity is beneficial to agricultural sector in addressing the bottlenecks in agriculture and as well empowering the stakeholders of agri value chain. In India, the start-ups working in the agricultural sector are confronted with two scenarios. One is, they account for only 7.37 % of total startups and the other is, only around 10.05 % are able to progress to scaling stage while more than 50 % are in their early stages of their life-cycle. Thus, the present study aims to understand the key drivers essential for agri start-ups to progress quickly through business life-cycle stages through a multi case study approach. As B2B is emerging as key revenue generating segment of agri tech start-ups, three agri tech start-ups in this segment having similar line of business and with common competition i.e., traditional agricultural markets are considered for the study. The findings indicated that higher education levels, expertise of managerial team and technological innovation are growth drivers through the ideation, validation and early traction stage. Strategic drivers namely vision, market-oriented opportunity switch, networking and market expansion are playing a key role in growth of identified start-ups. The short term and long-term strategic decisions pertaining to these strategic drivers derived out of day-to-day experiences and learning’s are major growth drivers in pushing the start-ups towards growth stage. While business strategies for achieving scalability, gaining investor confidence are vital growth drivers to attain scale-up stage. An improvement in operating revenues and assets derived out of growth factors is reflected in financial progress."

"This paper focuses on the importance of markets to the rural people and strategies to achieve the remunerative price of their produce in order to reduce hunger and poverty as well as promoting health and nutrition in Bihar. It also undertakes a situational analysis of existing marketing pattern, disposal pattern as well as expenses incurred while marketing of major vegetable crops in the target district of Bihar based on five year average of data collected from traders, producers and consumers for the period from 2013-2018. Pattern of marketing of major vegetables in the selected markets indicated that there was an increasing trend in arrivals and prices of different vegetables over different periods, it might be because of the increase in general price level and increase in population. However, the major focus was on development of entrepreneurs of proper enterprise based policy for enhancing livelihood security and establishment of procurement centres in each zone that would act as added incentives to the vegetable growers. Therefore reliance type of organized retail market at public- private mode should be initiated as an alternate channel for the marketing of vegetables and for dairy products in which value addition should be initiated by the farmers. Linking small farmers to markets would only be possible through an organized mandi /proper collection centres i.e. one centre for five villages should be established to assure the supply of vegetables in Bihar."

Evaluación de materiales oxídicos para la remoción de iones hierro y cobre en aguas naturales
Authors: Prato José G. , Yasaca Luis Sagnay , Millán Fernando , Padilla Carla Silva
Published: March 2024

La presencia natural de hierro y cobre en el agua es esencial para procesos ambientales, pero su explotación minera excesiva causa concentraciones elevadas, amenazando los ecosistemas debido a su capacidad de bioacumulación. El presente estudio se enfocó en evaluar la eficacia de sustratos adsorbentes elaborados a partir de materiales oxídicos de carga variable (SA, SCR, RV), para la remoción de hierro y cobre de soluciones acuosas. Los lechos fueron evaluados de forma natural y desprotonados mediante la activación con NaOH. Además, se examinó el equilibrio del proceso de adsorción de estos metales. Los resultados revelaron que el material natural SCR exhibe una destacada capacidad para retener tanto hierro (2.65 mg/100g) como cobre (17.89 mg/100g). Tras el tratamiento alcalino, se observó un aumento significativo en la capacidad de adsorción de los materiales, atribuida a la presencia de sesquióxidos en su estructura, siendo los materiales SCR (46.88 mg/100g, para hierro) y SA (38.24 mg/100g, para cobre) los más eficaces. Este aumento evidencia la versatilidad de estos sustratos de carga variable, en la remoción de iones metálicos. Los modelos de equilibrio sugieren que la adsorción es principalmente química y ocurre en una monocapa homogénea en la superficie del material. Esta investigación muestra que los materiales oxídicos naturales y activados son eficientes en la remoción de hierro y cobre, lo que es crucial para el tratamiento de aguas contaminadas por metales pesados

The results showed that, based on the IHL Review and its findings, the IHL serves as a legal basis to allow marriage dispensation in Law Number 16 of 2019 concerning marriage, where article 7 paragraph (2) and paragraph (4) stipulate that the minimum age of prospective men and women is 19 years. In addition, the IHL serves as a review of judges' deliberations when they decide to apply marriage dispensation.

Efisiensi kinerja jalan dipengaruhi oleh arus menyilang yang mengganggu lalu lintas akibat perpindahan lajur. Tujuan yang hendak dicapai adalah mengetahui pengaruh weaving terhadap kapasitas jalan arteri primer, membuat simulasi dan kalibrasi data lapangan menggunakan SUMO, menentukan rekomendasi pengendalian arus menyilang. Sampai saat ini belum ada penelitian tentang analisis arus menyilang pada jalan arteri primer yang menggunakan analisa karakteristik lalu lintas yang dikalibrasi menggunakan aplikasi SUMO. Data volume tertinggi segmen non-weaving sepanjang periode survei digunakan simulasi sumo. Hasil simulasi berupa meanSpeed akan dibandingkan dengan perhitungan nilai kecepatan rata-rata data lapangan. Nilai output simulasi akan dikalibrasi hingga nilai kecepatan rata-rata data lapangan mendekati ouput SUMO. Kalibrasi dilakukan dengan cara membuat variasi input nilai departSpeed. Hasil penelitian yang diperoleh adalah nilai kapasitas pada segmen non-weaving lebih besar jika dibandingkan dengan kapasitas pada segmen weaving sehingga dapat diinterpretasikan bahwa arus menyilang menyebabkan penurunan kapasitas jalan arteri primer. Data lapangan menghasilkan nilai kecepatan rata-rata sebesar 4,82 meter/detik. Hasil simulasi adalah 1,21 meter/detik dengan kesesuaian terhadap data lapangan 25,16%. Ouput hasil kalibrasi 4,98 meter/detik memiliki kesesuaian dengan data lapangan sebesar 96,68%. Rekomendasi pengendalian arus menyilang untuk mereduksi kemacetan adalah penggunaan median jalan dengan kecepatan rata-rata sebesar 13,44 meter/detik meningkat sebesar 64,12%.

Authors: Babona Ukobizaba Nduwayezu
Published: March 2024

Purpose: The work at hand examines the effects of cultural texts, integrated in the language teaching and learning, on students’ communicative competence in third and fourth forms secondary school. It has been noticed that some teachers of English do not yet distinguish a literary (cultural) text from a scientific or technical one precisely while determining pedagogic purposes.

Methodology: To gather data in this research, an experimental study was conducted in third and fourth forms secondary school in Goma.

Findings: The overall findings have revealed that cultural texts influence both reading comprehension, retelling and interpretation skills, a real gateway to communicative competence enhancement. In other words, this study brings a new vision to the practice of communicative activities as currently carried out in Goma secondary schools. 

Unique contribution to theory, policy and practice: It arises English teachers’ concern not only for the message expressed by the text, but also for the exploitation of students’ cultural values and schemata to heighten their communicative competence.
