Confirmatory Factor Analysis of the Malay-Language Transtheoretical Model of Physical Activity among Malaysian Primary School Children

Introduction: The transtheoretical model (TTM) is an integrative model of intentional change consisting of stages of change, processes of change, decisional balance and self-efficacy. This study aimed at validating the TTM questionnaires on physical activity for Malaysian children using confirmatory factor analysis. Methods: The participants were 381 Malay students (188 male; 193 female), aged 10–12 years old, with a mean age of 10.94 (SD = 0.81). The original version of the TTM was translated into the Malay language using forward and backward translation. Certain phrases were adapted based on the local culture and vocabulary suitable for primary school students. Results: The final measurement models and their fit indices were: processes of change (CFI = 0.939, TLI = 0.925, SRMR = 0.040, RMSEA = 0.030); decisional balance (CFI = 0.897, TLI = 0.864, SRMR = 0.045, RMSEA = 0.038); and self-efficacy (CFI = 0.934, TLI = 0.915, SRMR = 0.042, RMSEA = 0.032). Conclusion: Care must be taken when using the TTM with children, as it has been prevalently validated with adults. The final version of the TTM questionnaire for Malay primary school children had 24 items for process of changes, 13 items for self-efficacy and 10 items for decisional balance

The Effects of Brain Breaks on Motives of Participation in Physical Activity among Primary School Children in Malaysia

Brain breaks is a physical activity (PA) video designed for school settings that is used to stimulate student’s health and learning. The purpose of this study is to measure the effects of brain breaks on motives of participation in PA among primary school children in Malaysia. Purposive sampling was used to divide 159 male and 176 female students aged 10 to 11 years old, mean (standard deviation (SD)) = 10.51 (0.50), from two schools in Kelantan, Malaysia into intervention (n = 183) and control (n = 152) groups. Students undertook brain breaks activities on school days (five minutes per session) spread out for a period of four months. Mixed factorial analysis of variance (ANOVA) was used to test the students’ motives of participation in PA for pre-, mid-, and post-tests using the Physical Activity and Leisure Motivation Scale-Youth-Malay (PALMS-Y-M). Mixed factorial ANOVA showed significant changes in enjoyment, F(2, 392) = 8.720, p-value (ηp2) = 0.001 (0.043); competitiveness, F(2, 195) = 4.364, p-value (ηp2) = 0.014 (0.043); appearance, F(2, 392) = 5.709, p-value (ηp2) = 0.004 (0.028); and psychological condition, F(2, 392) = 4.376, p-value (ηp2) = 0.013 (0.022), whereas mastery, affiliation, and physical condition were not significant (p < 0.05). Further post-hoc analysis revealed a significant downward trend in the control group (p < 0.05). Brain breaks is successful in maintaining students’ motives for PA in four of the seven factors.</jats:p

Approaches in biotechnological applications of natural polymers

Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. As definition, gums and mucilages are polysaccharides or complex carbohydrates consisting of one or more monosaccharides or their derivatives linked in bewildering variety of linkages and structures. Natural gums are considered polysaccharides naturally occurring in varieties of plant seeds and exudates, tree or shrub exudates, seaweed extracts, fungi, bacteria, and animal sources. Water-soluble gums, also known as hydrocolloids, are considered exudates and are pathological products; therefore, they do not form a part of cell wall. On the other hand, mucilages are part of cell and physiological products. It is important to highlight that gums represent the largest amounts of polymer materials derived from plants. Gums have enormously large and broad applications in both food and non-food industries, being commonly used as thickening, binding, emulsifying, suspending, stabilizing agents and matrices for drug release in pharmaceutical and cosmetic industries. In the food industry, their gelling properties and the ability to mold edible films and coatings are extensively studied. The use of gums depends on the intrinsic properties that they provide, often at costs below those of synthetic polymers. For upgrading the value of gums, they are being processed into various forms, including the most recent nanomaterials, for various biotechnological applications. Thus, the main natural polymers including galactomannans, cellulose, chitin, agar, carrageenan, alginate, cashew gum, pectin and starch, in addition to the current researches about them are reviewed in this article.. }To the Conselho Nacional de Desenvolvimento Cientfíico e Tecnológico (CNPq) for fellowships (LCBBC and MGCC) and the Coordenação de Aperfeiçoamento de Pessoal de Nvíel Superior (CAPES) (PBSA).

Integrated approach to Wire Arc Additive Manufacturing (WAAM) optimization: Harnessing the synergy of process parameters and deposition strategies

The flexibility of Additive Manufacturing (AM) technologies in the metal 3D printing process has gained significant attention in research and industry, which allows for fabricating complicated and intricate Near-Net-Shape (NNS) geometry designs. The achievement of desired characteristics in Wire-Arc Additive Manufactured (WAAM) components is primarily contingent upon the careful selection and precise control of significant processing variables, including bead deposition strategy, wire materials, type of heat source, wire feed speed, and the application of shielding gas. As a result, optimizing these most significant process parameters has improved, producing higher-quality WAAM-manufactured components. Consequently, this has contributed to the overall rise in the method's popularity and many applications. This article aims to provide an overview of the wire deposition strategy and the optimization of process parameters in WAAM. The optimization of numerous wire deposition techniques and process parameters in the WAAM method, which is required to manufacture high-quality additively manufactured metal parts, is summarised. The WAAM optimization algorithm, in addition to anticipate technological developments, has been proposed. Subsequently, a discussion ensues regarding the potential for WAAM optimization within the swiftly growing domain of WAAM. In the end, conclusions have been derived from the reviewed research work

Sinekologi Padang Lamun Dan Makroinvertebrata Asosiatifnya Pada Perairan Dengan Monsoonal Wave Climate: Studi Kasus Pulau Panjang Kepulauan Derawan

Padang lamun di reef flat Pulau Panjang Kepulauan Derawan merupakan ekosistem laut dangkal produktif dan habitat yang menopang keanekaragaman hayati yang tinggi. Sebagai bagian dari Indonesia Maritime Continent (IMC), Pulau Panjang berada dalam pengaruh siklus angin monsunal. Sejauh ini belum tersedia informasi mengenai dinamika ekosistem (sinekologi) padang lamun beserta komunitas makroinvertebrata asosiatifnya yang berkaitan dengan siklus angin monsunal. Tujuan utama penelitian adalah untuk mendapatkan model dinamika padang lamun beserta komunitas makroinvertebrata asosiatifnya sebagai respon terhadap siklus monsunal di Pulau Panjang Kepulauan Derawan. Guna mencapai hal tersebut, dirumuskan tujuan khusus antara lain; (1) Menganalisis pengaruh siklus monsunal terhadap hidrodinamika perairan Pulau Panjang, (2) Menganalisis pengaruh siklus monsunal terhadap fluktuasi musiman variabel fisik kimia perairan Pulau Panjang, (3) Menganalisis dinamika monsunal ekosistem padang lamun Pulau Panjang, (4) Menganalisis dinamika monsunal makroinvertebrata asosiatif padang lamun Pulau Panjang dan (5) Menganalisis keterkaitan komunitas makroinvertebrata dan padang lamun terhadap variabilitas lingkungan ekosistem padang lamun Pulau Panjang. Pendekatan penelitian bersifat interdisipliner, pola angin dikaji dengan model windrose serta perhitungan indeks monsunal yang selanjutnya ditransformasikan menjadi gelombang terbangkit angin. Kombinasi PERMANOVA (Permutational Multivariate Analysis of Variance) dan NMDS (Non-metric Multi Dimensional Scaling) digunakan untuk melihat dinamika antar musim keanekaragaman beta dari padang lamun dan komunitas makroinvertebrata. Kemudian untuk mengetahui keterkaitan antara parameter lingkungan terhadap padang lamun maupun komunitas makroinvertebrata diselidiki dengan teknik CCA (Canonical Correspondence Analysis). Hasil analisis menunjukkan bahwa puncak Monsun Timur Laut (Desember-Maret) dan Monsun Barat Daya (Juni-September) berasosiasi dengan peningkatan intensitas dan tinggi gelombang membentuk Monsoonal Wave Climate. Analisis multitemporal menunjukkan bahwa siklus monsunal memantik fluktuasi musiman sebagian variabel fisik kimia perairan ekosistem padang lamun Pulau Panjang. Dinamika fisik kimia perairan tersebut berkaitan dengan faktor intrinsik dan ekstrinsik setiap variabel. Penelitian menemukan 186 jenis Makroinvertebrata yang berasal dari 8 Kelas dan 64 Famili berasosiasi dengan 6 jenis vegetasi lamun di Pulau Panjang. Vegetasi lamun menunjukkan kestabilan kondisi antar musim sedangkan makroinvertebrata asosiatifnya menunjukkan kondisi yang sedikit variatif. Keanekaragaman beta makroinvertebrata pada Monsun Timur Laut berbeda terhadap Monsun Barat Daya dan kedua periode Transisi. Bagaimanapun dinamika padang lamun dan makroinvertebrata asosiatifnya berada pada kondisi yang relatif baik. Hal ini mengindikasikan tingginya kemampuan resistensi dan resiliensi ekosistem padang lamun, serta terjaganya keanekaragaman dan kelimpahan xiii makroinvertebrata pada level yang tinggi antar musim. Dengan demikian, interaksi mutualisme antara padang lamun dan komunitas makroinvertebrata di Pulau Panjang memfasilitasi kemunculan sifat kolektif dan sifat emergen yang meningkatkan resistensi, resiliensi dan adaptabilitas ekosistem terhadap fluktuasi kondisi lingkungan baik yang dipicu siklus monsunal secara langsung maupun tidak langsung
