Thyroid Carcinoma Recurrence Prediction Using Artificial Intelligence On Prognosis Parameter, Supawat Suntornlimsiri

Chulalongkorn University Theses and Dissertations (Chula ETD)

Papillary thyroid carcinoma (PTC) is the most common subtype of thyroid malignancy and is increasingly diagnosed worldwide. Although typically localised, PTC exhibits a notable risk of bilateral involvement, with contralateral disease occurring in up to 44 percent of cases. While completion thyroidectomy is recommended in selected high-risk scenarios, it carries potential complications, making accurate prediction of contralateral involvement essential. This study investigates the utility of classical statistical methods and machine learning (ML) algorithms—Support Vector Machines (SVM), Extreme Gradient Boosting (XGBoost), and Random Forest (RF)—in predicting contralateral PTC using a retrospective dataset of 122 lobectomy patients. ML models, especially RF with …

Cumulative Environmental Impacts In Thailand : A Legal Appraisal Of The Eia Regime Under Neqa, Leila Kenza Cherkaoui

Chulalongkorn University Theses and Dissertations (Chula ETD)

This Research examines the limitations of Thailand’s Environmental Impact Assessment (EIA) framework under the Enhancement and conservation of National Environmental Quality Act B.e. 2535 (1992) (NEQA), with a focus on its failure to address cumulative environmental impacts in tourism-intensive regions such as Phuket, Koh Samui, and Chiang Mai. While EIA was originally introduced to ensure that environmental risks are considered before project approval, in practice Thailand’s system remains narrowly projectbased, overlooking the combined effects of multiple small and medium scale development that together exceed ecological carrying capacity. This has contributed to serious environmental degradation, including coral reef decline, freshwater depletion, …

The Risk–Reward Trade-Off Of Hedging In Trade And Security: Trump’S First Administration And Its Impacts On Thailand, Qiyu Zhang

Chulalongkorn University Theses and Dissertations (Chula ETD)

Against the backdrop of an increasingly polarized global landscape and intensifying Sino-American competition, this paper conducts an in-depth analysis of the risk-reward trade-offs inherent in Thailand’s ‘hedging strategy’ during Donald Trump’s first term (2017-2021). Hedging policy occupies a middle ground between “alignment” and ‘balancing’, aiming to diversify risks and maintain flexibility. It constitutes a strategic approach enabling nations to derive benefits from great power competition while preserving avenues for retreat. Through in-depth research, this paper finds that Thailand, as a small power, gained short-term economic benefits through its hedging strategy, such as manufacturing relocation and export growth. However, these gains …

The Information Spillover Effects Of Earnings Announcements: Evidence From Thailand, Panatakorn Piyawannasuth

Chulalongkorn University Theses and Dissertations (Chula ETD)

AbstractThis research investigates spillover effects during announcement days in the Thai stock market, covering the period from 2015 to 2024, covering all publicly traded companies on the Stock Exchange of Thailand. The paper aims to determine whether limited spillover effects in developed markets persist in emerging markets whose institutional features are quite different.The empirical evidence strongly confirms that Thai earnings announcements are made up predominantly of firm-specific information, as compared with industry-level information, consistent with developed-market profiles. The conditional spillover study, however, reveals characteristic Thai capital market characteristics. Firms reporting significant earnings surprises demonstrate no systematic evidence in precipitating larger …

Using quarterly mutual fund holdings from Morningstar and transaction-level data from the Thai Bond Market Association (ThaiBMA) between 2015 and 2024, the analysis examines whether mutual funds exhibit “Flight from Liquidity” behavior—selling their most liquid assets under stress—and how such behavior affects bond yield spreads.Three hypotheses are tested. First, whether mutual funds are more likely to sell government bonds than corporate bonds during distress periods. Second, whether funds exhibit flight-from-liquidity behavior within each bond segment by selling …

The Moderating Role Of Investor Sentiment Regimes On The Impact Of Flow Types On Capital Structure Decisions (Evidence From Thailand), Shiva Sachaphimukh

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study analyzes how foreign and domestic capital flows influence the leverage of SET100 Thai non-financial firms, considering investor sentiment regimes and firm cyclicality (2013–2023). It contrasts fundamental foreign portfolio flows with speculative domestic trading turnover. Sentiment regimes powerfully amplify flow effects. Bullish domestic sentiment and high domestic turnover significantly increase leverage (sentiment-exploitation). Conversely, deteriorating sentiment and foreign outflows intensify debt reliance (stress-compensation). Domestic flows have stronger, more immediate leverage effects than foreign flows, revealing a behavioral asymmetry. Cyclical firms respond aggressively to domestic factors and sentiment, while non-cyclical firms prioritize foreign capital stability.The findings highlight the critical role of …

Salience, Trading Volume And 52-Week High Effects On Stock Returns: Evidence From Thai Stock Market, Tonnsaai Anantrechai

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study examines the interaction between salience effects and the 52-week high phenomenon in the Thai stock market, with particular attention to the mediating role of trading volume. Using data from SET100 constituents spanning May 2005 to December 2024, we employ the salience measure developed by Bordalo et al. (2012) and Cosemans and Frehen (2021) to investigate whether stocks with salient payoffs exhibit different return patterns when approaching their 52-week highs. Following Lin (2024), we test whether abnormal trading volume amplifies these behavioral effects. Our findings reveal a notable discrepancy: while historical portfolio sorts show extreme return differentials between salience …
