Experiential Learning of Using Digital Tools in Construction Management Education

The Fourth Industrial Revolution (IR4.0) is gradually reshaping the entire construction industry. It is not an option that skills and abilities in a wide range of digital technologies should be part of the construction management curriculum. The sheer lack of skills and expertise in the shift to digital construction is related to the insufficiency of hands-on activities using various digital tools. This study outlines the experience learning of utilising digital tools in construction management education. The purpose of this article is to investigate the extent to which Experiential Learning Theory (ELT) influences students' perceptions of digital tools. The student association in the construction management programme offered at Universiti Teknologi MARA (UiTM) designed and organised a hands-on workshop activity approach to address the issue of lack of proficiency in using digital tools such as Autodesk Revit (BIM system), Microsoft Excel (Quantity Take-Off). The method begins with a basic grasp of digital tools for construction-related applications. Then, step by step, explores the computer interface ribbons, shortcuts, and associated tabs. The proposed method is examined in faculty computer laboratories by employing practical learning for both digital tools (i.e. Revit and Excel) in either creating a three-dimensional (3D) BIM Model or the capacity to calculate material amounts. Based on the assessment results, the strategy helps students master the digital tools and implement such activities in their official course module

Kajian Kesepadanan Ukuran Kerusi Dan Meja Belajar Dengan Antropometrik Pelajar Sekolah Rendah Di Malaysia.

Dalam menjalani aktiviti pembelajaran seharian, pelajar sekolah lebih menghabiskan masa mereka di kerusi dan meja belajar. Pelajar menghabiskan waktu pembelajaran selama 6–7 jam iaitu 80% dan masa yang dihabiskan oleh pelajar itu adalah dengan menggunakan kerusi dan meja belajar disekolah untuk menjalani aktiviti pembelajaran mereka seperti membaca, menulis, mengira, melukis, makan, minum dan sebagainya. Mengikut kajian, penggunaan kerusi dalam tempoh yang panjang serta dengan posisi postur yang salah boleh mendatangkan beberapa masalah terhadap diri pelajar tersebut. Antaranya adalah punca masalah dalam meningkatkan sumber daya pelajar yang berkualiti akan berkurang kerana pelajar akan berasa terganggu, letih serta hilang tumpuan dalam pembelajaran sekiranya penggunaan mereka terhadap kerusi dan meja belajar yang tidak selesa. Ketidakserasian tersebut juga boleh mengakibatkan risiko pada diri pelajar seperti mengalami trauma kesakitan MSD – Musculaskeletal Disorder. Trauma kesakitan ini kebiasaanya berpunca bermula dari peringkat awal bergantung dengan cara penggunaan pelajar terhadap kerusi dan meja belajar. Sekiranya kerusi dan meja belajar yang tidak sesuai dengan ukuran badan pelajar, ia boleh mengakibatkan pelajar mengalami kesukaran dalam penumpuan terhadap pembelajaran dan juga trauma kesakitan dalam jangka masa yang lama. Oleh yang demikian, keselesaan pelajar terhadap penggunaan kerusi dan meja belajar memainkan peranan yang penting bagi membantu proses pembelajaran mereka dengan lebih efektif. Proses kajian yang dijalankan bagi mencapai tahap keselesaan dan kesan yang efektif dalam reka bentuk kerusi dan meja belajar adalah melalui ukuran perabot tersebut dengan postur dan saiz badan pelajar dengan menggunakan kaedah antropometrik (ukuran saiz tubuh dan bentuk fizikal pelajar). Penggunaan kaedah ini dapat membantu meminimumkan permasalahan serta risiko ergonomik yang boleh dialami oleh pelajar sama ada pada masa sekarang atau impak pada masa akan datang. In daily activities of learning, 80% of the time spend by a student is by sitting on the chair and using desk, which makes 6-7 hours in a day. Sitting on a chair for long period can cause some problems to the student, which will eventually decrease the uncomfortable and incompatibility issues. On the other hand if the chair and desk provided to the student is uncomfortable then the student will feel distracted and lose focus on learning and also have a high risk of developing trauma pain MSD - Musculoskeletal Disorder. Trauma pain is usually stems from an early stage and depends on the quality and use of the chair and desk by the student. The convenience and compatibility in the design of chair and desk with student play an important role in assisting student learning process more effectively. The main aim of the study is to improve the compatibility of chairs and desks using by primary school students. Thus, the corresponding study design of chairs and desks were done through the furniture size, body size and posture using anthropometric methods. The use of these methods can help to minimize the risk of ergonomic problems experienced by students in the present and also have a great impact in the future. This study emphasizes on the planning and development of design chairs and desks that are appropriate to the anthropometric (size and shape of the physical size of the student body) and to produce the guidelines in the design of chairs and desks that are more ergonomic, practical and of good quality

Study On Compatibilities Of Anthropometric Measurement On Learning Desks And Chairs With Primary School Student In Malaysia

In our daily activities of learning, 80% of the time spend by a student is by sitting on the chair and using desk, which makes 6-7 hours in a day.Based upon the findings of Savanur et al (2007) (Advance in Ergonomics in Design, Usability and Special Populations, Part II) said 'students spend about a quarter of teh day (6hours) in school, and 60% to 80% of that time is spent in the classroom'

Synthesis of nanocomposite 2-methyl-4-chlorophenoxyacetic acid with layered double hydroxide : physicochemical characterization and controlled release properties

A new organic–inorganic hybrid nanocomposite Zn–Al-MCPA-layered double hydroxide (ZAM) was prepared by intercalation of 2-methyl-4-chlorophenoxyacetic acid (MCPA) into Zn–Al-layered double hydroxide (ZAL) at various concentration of MCPA ranging from 0.1 to 0.7 M. The pH of the synthesis was kept constant at 7.5. Well-ordered hybrid nanocomposite was obtained with 0.4 M MCPA with an expansion of basal spacing from 8.9 Å in the ZAL to 19.7 Å in the resulting nanocomposite. The FTIR spectra of the nanocomposite show resemblance peaks of the MCPA and Zn–Al-layered double hydroxide indicating the inclusion of MCPA into the layered double hydroxide. The average particle size of ZAL and ZAM in this study was 115 and 128 nm, respectively. Percentage loading of MCPA was found to be 45.0 % (w/w), calculated based on the percentage of carbon in the sample. The release of MCPA into various aqueous solution was found to be dependent to the anion in the aqueous solution in the order of phosphate > sulfate > chloride with the percentage release of 80, 44, and 8 %, respectively. This study shows that Zn–Al-layered double hydroxide can be used as a host carrier for herbicide, MCPA, with controlled release capability

Physicochemical properties, sensory evaluation and storage stability of vitamin E fortified pink guava juice / Aishah Bujang … [et al.]

Pink guavas (Psidium guajava L.) are tropical, climateric fruits that are commonly grown in Malaysia for juice and puree production. These fruit are highly aromatic and rich in potassium, vitamin A and C. It is well known that guava fruit contains significantly more vitamin C than most citruses. Vitamin C is a powerful antioxidant and anti-inflammatory agent. Pink guavas also have a high level of lycopene, a carotenoid which is considered good for fighting free radicals. Currently, Sime Darby Golden Hope Foods and Beverages company is the single largest pink guava plantation in the world with over 500 hectares of the fruit grown in Sitiawan, Perak. It is the only pink guava plantation in Malaysia and the largest integrated facility in Asia. The fruit are hand-picked and processed into puree and hygienically packed into aseptic bags and sealed in steel drums for overseas export market or process into ready-to-drink juice in tetrapak packaging for local market. Normally, fruit juices are cloudy in appearance, have a lot of colloidal suspensions that are either preferred by some consumers or considered as unattractive to the others. The juice cloudiness is contributed by the presence of different components (cell wall fragments, cellular organelles, oil droplets, hesperidin crystals, pectin etc.) together with polydisperse distribution of particles sizes (Sentandrau et al., 2011). The colloidal particles in the juices also carry flavour substances and natural antioxidants such as carotenoids, lycopene etc. Sedimentation of juice due to the presence of pulp particles caused the separation problem in most fruit juices. Addition of stabilising agent and homogenisation process are conducted to reduce the particle size of the sediments hence preventing separation from occurring. The choice of stabilisers used is also important depending on the properties of the juices. Starch, pectin, arabic gum, carrageenan gum, guar gum and xanthan gum are commonly used as stabilising agents in beverages. Homogenisation technique using ultrasonic vibrations and high-pressure homogenisers are nowadays used to disintegrate large fat globules into a more stable, small and uniform fat globules size. Sonication process is more preferred in food industries because of reduced processing time, higher throughput and lower energy consumption (Cheng et al., 2007)

A Preliminary Study of Parasitic Infections of Some Fishes from Kinabatangan River, Sandakan, Sabah

A survey of fishes of the Kinabatangan River was conducted to determine the fish types, abundance and prevalence of parasitic infection. The fishes were collected with gill nets in two distinct areas, named Abai and Bilit. Eleven fish species in ten genera and ten families were encountered. The family Ariidae formed 36.3% of the total number of individuals (n=80) while the rest were Pangasiidae (15%), Siluridae (11.3%), Cyprinidae (10%), Engraulidae (7.5%), Bagridae (6.3%), Toxotidae (6.3%), Sciaenidae (3.8%), Megalopidae (2.5%) and Clariidae (1.3%). Both ectoparasites and endoparasites especially intestinal helminth were recorded. The ectoparasite infestation rate was 45% whereas the endoparasite remain only 17.5%. The overall parasitic infection rate was more than half of sample (53.8%).This preliminary data indicated that almost half of the population of fishes from these areas could be exposed to parasitic infection

Effect of different degree of deacetylation, molecular weight of chitosan and palm stearin and palm kernel olein concentration on chitosan as edible packaging for cherry tomato

The palm stearin and palm kernel olein (PSPKOo) blend (at 31%) was incorporated into chitosan of different degree of deacetylation (DD) (85 and 95%) and molecular weight (MW) (100,000 and 300,000 Da) to form films, and the films were evaluated in terms of particle size, diameter and stability of emulsion, as well as thickness and tensile strength. The chitosan with 85% DD (MW 300,000 Da) and 31% PSPKOo blend resulted in the strongest film, while this chitosan varied with 15.5 and 31% of PSPKOo blends compared to physical properties of film. Emulsion blend containing 85% DD (MW 300,000 Da) and 31% PSPKOo blend of chitosan gave the biggest particle size, highest viscosity and the most stable emulsion, resulting in the thickest film with the highest tensile strength (TS) and elastic modulus (EM). The film was applied on cherry tomato and stored at 20C for 9 days. The chitosan film with 85% DD (MW 300,000 Da) and 31% PSPKOo blend was the most effective in reducing weight loss and maintaining firmness and redness of cherry tomato compared to the other two films. Hence, palm stearin (PS) showed potential to be used as a moisture barrier in fruit coating
