Mobility Revisited : The Illusion In Bangkok & Tokyo Transportation – A Comparative Analysis, Chai Skulchokchai
Mobility Revisited : The Illusion In Bangkok & Tokyo Transportation – A Comparative Analysis, Chai Skulchokchai
Journal of Urban Culture Research
This paper argues against the traditional notion of mobility by reinterpreting it through three concepts: Margin of Indeterminacy, Governmobility and Lefebvre’s Production of Space. The author chooses to compare the transportation of Bangkok and Tokyo based on direct experience and the city transportation’s respective notability. The paratransportation and decentralized transportation in Bangkok allows the city to have a wider margin of indeterminacy than Tokyo. By that, people in Bangkok has other alternatives when a major transportation has an issue. Tokyo depends primary on its railway. Foucauldian governmentality argued that mobility is another way where the government governs over the people. …

Chiang Mai’S Intangible Cultural Heritage : Urban Revitalization And Cultural Identity In A Northern Thai City, Alexandra Denes, Ajirapa Pradit
Journal of Urban Culture Research
Founded in 1296 CE, the walled city of Chiang Mai, Thailand was once the capital of the Lanna kingdom. In the sixteenth century, Chiang Mai’s fortunes waned, and it became a tributary state under the Burmese. This was followed by its incorporation into the Thai nation-state in the twentieth century. One outcome of Chiang Mai’s administrative integration into the Thai nation was the erosion of its distinctive cultural identity. Beginning in the 1980s, key local figures began to collaborate with communities and academic institutions to revitalize Chiang Mai’s intangible cultural heritage, including its craft traditions, rituals, textiles, and dance performances. …

Comparative Effectiveness Of Tongue Exercises On Tongue Strength, Endurance, And Movement In Healthy Young Adults : A Randomized Controlled Trial Study, Janistar Lekvichittada
Chulalongkorn University Theses and Dissertations (Chula ETD)
Background and rationale: Tongue strengthening exercise (TSE) is a program to re-educate the neuromuscular pattern of the tongue muscle to improve tongue posture and swallowing function. Various TSEs have been introduced. However, most studies have been conducted on TSEs focusing on instruments such as tongue blade, Iowa oral performance instrument (IOPI) and JMS tongue pressure measuring device. Only a few have focused on self-tongue strengthening exercises, which has yet to show which method is the best for improving tongue strength, endurance, and movement. Objective: This study aimed to investigate tongue-strengthening exercise methods that had the most significant impact on increasing …

Identification Of Chemical Components Of Fuel Derived From Two-Phase Electrolysis, Nafisat Lawal
Chulalongkorn University Theses and Dissertations (Chula ETD)
In this research, two-phase electrocoagulation approach was developed and used to investigate blend of bio-diesel and petro-diesel (B10) stability under the electrochemical treatment. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the aliquots before and after the reaction. It was observed that major compounds were alkanes and aromatic compounds with the minor contents of aldehydes, ketones, esters, alkenes, alkynes, halogens, oxygenated compounds, and heterocyclic compounds. Compounds with both smaller and larger carbon numbers were identified after the treatment. The optimum condition for the reaction was 10 V and 60 min which resulted in about 9.8x109 (counts s) total peak area …

Factors Associated With Unsafe Children's Stool Disposal: An Analysis From 2015-2016 Myanmar Demographic And Health Survey, Naw Lah Say Wah
Chulalongkorn University Theses and Dissertations (Chula ETD)
Introduction: Safe sanitation is essential for preventing the transmission of diarrhoeal diseases and other infections. Sanitation projects and programs targeted at household sanitation have paid little focus to the disposal of children's stools. Due to the common misconception of children’s stool as less infectious, parents improperly manage children's stools for disposal. Unsafe disposal of children's stools has become an unhindered part of public health problems primarily in low and middle-income countries. Objective: To identify the association between children's stool disposal methods and factors associated with unsafe children’s stool disposal methods in Myanmar Method: This study is the cross-sectional secondary data …

Exploring And Analysis Of Student Engagement In English Writing Grammar Accuracy Based On Teacher Written Corrective Feedback, Thanakorn Santanatanon, Sumalee Chinoku
Exploring And Analysis Of Student Engagement In English Writing Grammar Accuracy Based On Teacher Written Corrective Feedback, Thanakorn Santanatanon, Sumalee Chinoku
PASAA
Whether students benefit from written corrective feedback (WCF) may depend on their level of engagement with the feedback. To date, student engagement with written corrective feedback has been investigated qualitatively. However, the association between student engagement with feedback and learning outcomes that result from that engagement has not been thoroughly examined. Moreover, little attention has been paid to secondary students’ engagement with written corrective feedback because most studies have focused on university students. Therefore, this mixed-method experimental study was conducted to discern if there was an association between student engagement with feedback and English writing grammar accuracy and to explore …
