An Implementation Of An Integrated Performance Assessment Module To Promote English Speaking Ability And Learning Engagement Of Undergraduate Students, Benjawan Plengkham
Chulalongkorn University Theses and Dissertations (Chula ETD)
Integrating assessment with instruction has been a challenge for English language teachers, especially in English speaking courses. Therefore, it is crucial to incorporate instruction and assessment methodologies that can help enhance students’ speaking ability. The Integrated Performance Assessment (IPA), designed by the American Council on the Teaching of Foreign Languages (Adair-Hauck et al., 2015), is a cluster assessment consisting of three modes of communication, namely interpretive, interpersonal, and presentational, to seamlessly connect instruction and assessment as well as reflect how students use the language. This study was conducted to 1) investigate the effects of an IPA module on undergraduate students’ …

Flow-Performance Relationship In Defi Yield Aggregator, Apisara Pornprasith
Flow-Performance Relationship In Defi Yield Aggregator, Apisara Pornprasith
Chulalongkorn University Theses and Dissertations (Chula ETD)
Decentralized Finance (DeFi) is a new financial infrastructure with applications similar to traditional financial products, such as exchange, lending, derivatives, and asset management. This paper empirically investigates Yearn finance, one of the fastest-growing and largest in DeFi yield aggregator protocols for on-chain asset management, to demonstrate the flow-performance relationship and compare it with mutual funds in traditional finance. According to the findings, there is a positive non-linear relationship between fund flows and recent performance for using stablecoin deposited. In contrast, we cannot find this relationship for using cryptocurrency. Then, we look further into stablecoin holder behaviour and our findings show …
Development Of High Protein Beverage From Hydrolyzed Egg White, Nuntorn Charoensak
Development Of High Protein Beverage From Hydrolyzed Egg White, Nuntorn Charoensak
Chulalongkorn University Theses and Dissertations (Chula ETD)
The primary objective of this study was to examine the impact of enzymatic treatment on pasteurized egg white protein (EWP) and assess its influence on various physicochemical properties and antioxidant activity. Our findings revealed that the addition of SDAY10 enzymes led to a significant increase in lightness (L*), redness (a*), and yellowness (b*) parameters. Furthermore, higher concentrations of the enzyme resulted in a considerable reduction in pH, viscosity, and volume mean diameter (D4,3) of EWP protein compared to the control group (P < 0.05). Additionally, the application of SDAY10 enzyme (0.1-0.3% w/v) for EWP hydrolysis exhibited a noteworthy enhancement in antioxidant activity (measured by DPPH, ABTS, and FRAP assays) compared to lower enzyme concentrations. Notably, the 0.3% concentration of SDAY10 exhibited the highest release of amino acids during in vitro digestion and received the highest sensory evaluation score. Consequently, employing SDAY10 enzymes at a concentration of 0.3% w/v for EWP hydrolysis demonstrates significant potential for improving the physical properties of EWP and enhancing antioxidant activity. However, it is imperative to investigate the sensory evaluation with regards to the bitterness of the product developed using such enzymes.

Assessment Of Greenhouse Gases Emissions From Dairy Cattle Production In Thailand, Phoo Pwint Pwint Thu
Chulalongkorn University Theses and Dissertations (Chula ETD)
Thailand’s agriculture sector plays a vital role in driving economic growth. Globally, livestock production is estimated to contribute about 18% of greenhouse gas (GHG) emissions. Despite its importance, there is a relative lack of research on GHGs assessment in the livestock sector in Thailand. The aim of this research was to estimate GHGs emissions from dairy cattle production in Saraburi and Ratchaburi provinces of Thailand. The 2019 Refinement to the 2006 IPCC guidelines for national greenhouse gas inventories was applied in this research. Twenty dairy farms (n=20) including both small farms (n=10) and medium farms (n=10) were selected as the …

Effects Of Chitosan Oligosaccharide And Probiotics On Chronic Kidney Disease Rats, Weerapat Anegkamol
Effects Of Chitosan Oligosaccharide And Probiotics On Chronic Kidney Disease Rats, Weerapat Anegkamol
Chulalongkorn University Theses and Dissertations (Chula ETD)
Chronic kidney disease (CKD) patients suffer from the accumulation of toxic substances in their blood due to the loss of kidney function, which results in hyperphosphatemia. This condition contributes to hyperparathyroidism, leading to the development of chronic kidney disease-related mineral bone disorder (CKD-MBD). Additionally, CKD patients experience changes in their gut microbiota, disrupting epithelial tight junctions and allowing excessive absorption of dietary phosphate. In this study, we aimed to investigate the effects of various oligosaccharides and probiotics on the gut microbiota, intestinal barrier, hyperphosphatemia, and hyperparathyroidism in CKD rats. We isolated Lactobacillus and Bifidobacterium strains from healthy participants and tested …

Accuracy In Classification Of Liver Lesion Ultrasound Using Artificial Intelligence, Sutthirak Tangruangkiat
Chulalongkorn University Theses and Dissertations (Chula ETD)
B-mode ultrasound imaging is the standard method for hepatocellular carcinoma (HCC) screening. If a lesion has a unique appearance, a conventional detector can be applied. However, if the lesion shares its appearance with other lesion, a large training dataset is required, which may be unavailable. Therefore, a two-stage method is proposed. In the first stage, lesions are detected but not differentiated into any particular class. The detected lesions are then classified in the second stage using a conventional convolutional neural network (CNN). The aims of the dissertation are to design an artificial intelligent system model and to investigate the most …
Comparing The Success Rate Of Pleurodesis With Thoracoscopic Talc Poudrage Combined With Indwelling Pleural Catheter Versus Thoracoscopic Talc Poudrage In Patient With Malignant Pleural Effusion, A Randomized, Non-Inferiority Clinical Trial, Jitanong Sootlek
Chulalongkorn University Theses and Dissertations (Chula ETD)
Background: Malignant pleural effusion (MPE) can cause dyspnea symptoms that greatly impact a patient's quality of life. Talc pleurodesis or indwelling pleural catheter (IPC) insertion are two treatment options that can prevent recurrent MPE, alleviate dyspnea, and improve quality of life. However, talc pleurodesis requires a lengthy hospital stay, while IPC insertion is associated with lower pleurodesis success rates. Due to limited hospital bed capacity, we have devised a practical approach to managing MPE by combining TTP and IPC. Objective: This study aims to evaluate the efficacy of combined Thoracoscopic talc poudrage (TTP) and IPC compared to TTP alone in …

Development Of An Artificial Intelligence Model For Prediction Of Dry Weight In Chronic Hemodialysis Patients And Assessment Of Its Accuracy Compared To Standard Bioelectrical Impedance Analysis, Nataphut Boonvisuth
Chulalongkorn University Theses and Dissertations (Chula ETD)
Proper determination of dry weight (DW) is crucial for achieving positive outcomes in hemodialysis (HD) patients. However, the traditional clinical assessment of DW (C-DW) is often inaccurate. Recently, bioimpedance spectroscopy (BIS) analysis using a Body Composition Monitor (BCM) device has emerged as a gold standard method for determining DW (BCM-DW). Despite its accuracy, the high cost of the BCM device limits its accessibility. To overcome this challenge, the current study proposes a machine learning (ML) model, which is a part of artificial intelligence (AI), to assess DW using available clinical and laboratory parameters. Objective: To develop an ML model for …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Scaffold plays a key role in the context of tissue engineering. It not only provides a structural support for cells, but also creates an appropriate milieu for recruited cells, enhancing the therapeutic effects of cell-based treatments, and enabling the controlled release of biological cues such as growth factors. Collagen is widely used scaffold material in tissue engineering, particularly in periodontal and bone regeneration. Other natural polymers, however, have been developed and can be useful. Therefore, in this study, we aim to investigate the ability of four different natural polymers including collagen, chitosan, silk fibroin, and silk fibroin/gelatin hydrogel in promoting …
