title: EFFECTS OF WRITING INSTRUCTION BASED ON TOULMIN MODEL IN FLIPPED LEARNING ENVIRONMENT ON ARGUMENTATIVE WRITING ABILITY OF UNDERGRADUATE STUDENTS

description: The objectives of this study were 1) To examine the effects of writing instruction based on Toulmin model in flipped learning environment on argumentative writing ability of undergraduate students, and 2) To explore the students’ perceptions towards writing instruction based on Toulmin model in flipped learning environment. The samples were 17 English major seniors from Mahasarakham University who enrolled in Expository and Argumentative writing course in the first semester of academic year 2015. The experiment was held for 10 weeks. The data were collected quantitatively and qualitatively. A paired-sample t-test was used to investigate the differences between the mean scores from the pre and post writing test. The qualitative data were analyzed using content analysis. The findings of the study revealed that 1) there was a significant difference in students’ mean scores on English writing abilities before and after the implementation of the writing instruction at the significant level of .05, and 2) students had positive perception of the writing Instruction based on Toulmin model in flipped learning environment. They said that the writing instruction improved their argumentative writing ability since it allowed them to expose to prior contents and practice more in class. They also received more feedback and helps from the teacher too. However, some students said that they had difficulties in learning due to technology problems, and the limitation of time for writing in class.

title: SOUTH KOREAN GOVERNMENT'S ROLES INSUPPORTING WOMEN'S STATUS THROUGH THE SAEMAUL UNDONG PROJECT

description: Confucian ideology had influenced on Korean society since Chosun period. Women’s roles are traditionally limited in household. However, they control and manage most family affairs according to Hyunmo-Yangcho idea (good wife, wise mother). In 1960s, the standards of living by industrialization and modernization motivated rural women to be more responsible for household income. Most of them helped their families by leaving to cities and started working. There were changes in women’s social and economic roles. They had inspiration to participate in social affairs. The government initiated rural development strategy. They proposed the Fourth Five-Year National Economic Development Plan by introducing Saemaul Undong to rural villages nationwide. In 1970s, group of woman in Oryu village led by Mrs. Chung Moon-ja started forming the first women organization called Saemaul women’s club. Saemaul women’s club aimed to actively perform the projects for village income. Oryu village later became the best village reserve and wealthy community. The government wished to promote the famous successful Oryu village as another part of Saemaul Undong project. They thus used women as the key actor who practiced the major roles in national rural development. The result of the policy implementation is rural development emerged and successful. In addition, women who pushed Saemaul Undong to this success also benefited since their status was enhanced.

title: ENVIRONMENTAL IMPACTS OF MERCURY ON SOILS AND WATER RESOURCES IN SEKOTONG'S GOLD MINING VILLAGE IN LOMBOK ISLAND, INDONESIA

description: The update levels of mercury concentrations and other physicochemical properties in soil and water resources (shallow groundwater and river water) during rainy season in December 2014 were measured for two Sekotong’s gold mining villages in Lombok, Indonesia, named Tembowong (TE) and Gawah Pudak (GP) villages. The data revealed gold extracting processes involved at residential areas burden soil, groundwater, and river water with mercury. Mercury concentrations (mean ± SE) in groundwater at TE village (n=7) and GP village (n=7) were 0.081 ± 0.017 ug/L and 0.407 ± 0.328 ug/L, respectively. In average (± SE), mercury concentrations in soils (n=7) were found at 0.392 ± 0.170 mg/kg in GP village and at 0.265 ± 0.160 mg/kg in TE village. Active cyanidation (n=1) contributed mercury concentration on soils (0.522 mg/kg) and groundwater (0.170 ug/L) which is higher than amalgamation which was found in soils and groundwater at site with amalgamation facility (n=8) were found respectively at 0.139 ± 0.075 mg/kg and 0.064 ± 0.009 ug/L. At sites with a combination of active amalgamation and cyanidation, mercury concentrations (n=1) increased on the 1.175 mg/kg on soils and 1.268 ug/L in groundwater. The groundwater in GP and TE village contained high % saline (mean ± SE) 1.09 ± 0.43. The mean level (± SE) of groundwater dissolved oxygen (DO) at the villages was 1.72 ± 0.35 mg/L. The result shows the groundwater oxidation-reduction potential (ORP) was less than 650 mV. Soils in both villages (pH, 6.40–9.19) were more alkaline than the groundwater (pH, 5.80–8.00). The soils in GP village were found more alkaline, humidity, salinity, ORP, and had higher mercury than found in TE village; however there was a significant difference only in the ORP (p &lt; 0.01). At residences which also used as agricultural field (n=6), the mean level (± SE) of mercury was measured at 0.447 ± 0.385 ug/L in groundwater and at 0.455 ± 0.198 mg/kg in soils. Soil moisturizer was the only parameter associated positively to mercury concentrations of soils (rs=0.798). Besides, mercury concentrations (n=1) at the estuary zone were 1.764 ug/L, above the standard by US.EPA (&lt; 1 ppb).

title: A BUDDHIST APPROACH AS AN ALTERNATIVE ECONOMIC PARADIGM: A CASE STUDY OF INTERNATIONAL NETWORK OF ENGAGED BUDDHISTS

description: The 20th century was probably one of the most destructive in the history of human kind. As underlined by many scholars, the scale of the destruction on planet Earth in the last 60 years is highly superior to damages done by humans in the last 10 000 years; tremendous degradation of environment, galloping disparities in poverty, growing numbers of social revolutions, hunger - to name just a few elements of what is leading our existence into the braking point. We must assume that behind these destructive behaviours hides a global structure making them possible: the neoliberal capitalist economy. Based on idea of growth, powered by excessive greed, consumption and exploitation of natural resources, thanks to dogmatic and quasi-religious way of thinking, this economical hegemony shaped the global understanding of reality. There are no doubts that we cannot continue to follow the present economical way and we need a new economical paradigm. To face the mainstream economy, Buddhist tradition proposes a way based on spiritual wisdom. Within this master thesis I try to find the answer to the question of whether the spiritual, inner change, based on mystic knowledge, such as proposed by Buddhist economics, can constitute the counterpoint to the present neoliberal economy. In order to achieve it, I am analysing structures and actions of International Network of Engaged Buddhists, an NGO created by Professor Sulak Sivaraksa in 1989. I first define which elements of Buddhist spiritual wisdom are used by INEB in its main fields of activities such as alternative education, Buddhist economics, social enterprise or environment. In the second position I am looking for the practical application of this spiritual knowledge in order to verify its efficiency.

title: HANUMAN IN SAK YANT : THE SIGNIFICANCE AND INFLUENCE OF HANUMAN IMAGERY IN NORTHERN THAI CULTURE

description: The character Hanuman from the Ramayana is widely known across South and Southeast Asia, especially in Thailand. While modern scholarship on the character of Hanuman in Thailand is mainly focused on how he is viewed by the dominant Central Thai culture as a result of the state sponsored Ramakien, he is used by different communities to express local values. Many people get magical tattoos known as sak yant of him in hopes to emulate positive traits associated with his character. This thesis studies how the people who administer or receive Hanuman yants use his character to reflect cultural values as well as what traits of his they consider to be important. It also explains where Northern Thais knowledge of Hanuman comes from by analyzing local knowledge of his character and the influence of Central Thai culture on the region. Fieldwork was conducted in the Northern Thai provinces of Chiang Mai, Chiang Rai, and Lamphun by interviewing practitioners of sak yant and people who received Hanuman yants. The result of a qualitative analysis shows that Northern Thais glean their knowledge of Hanuman from a combination of local oral traditions and the influence of the dominant Central Thai culture. Northern Thais get Hanuman yants for compassion, protection, influence and fortune. Furthermore, Northern Thais use the this character to reflect their own personal and local cultural values.

title: AN INTERLANGUAGE PRAGMATIC STUDY OF THAI EFL LEARNERS' APOLOGY: LINGUISTIC REALIZATION AND METAPRAGMATIC AWARENESS

description: This study investigates the Thai EFL learners’ apologies and metapragmatic awareness in university contexts in interlanguage pragmatic perspectives. The research aims to investigate the effects of English language proficiency and experience on the Thai EFL learners’ pragmatic competence. The subjects consisted of six groups: native speakers of English (NE) and Thai (NT) and four groups of Thai EFL learners whose levels of English proficiency and experience differed. The results revealed that there were three apology strategies commonly found among the six groups of subjects: explicit display of an apology, expression of responsibility by admitting facts and offer of repair. The selection of apology strategies, however, differed depending on the situational variables, which suggests that different perceptions of such variables as well as different levels of English proficiency and experience can affect the selection of apology strategies among the subjects. It is also found that different levels of metapragmatic awareness could be observed among the four groups of Thai EFL learners. The Thai EFL learners with high English proficiency and experience demonstrated the highest level of metapragmatic awareness. Those with high English proficiency and low experience exhibited the higher level of metapragmatic awareness than those with low English proficiency and high Experience. The findings suggest that (1) the high level of English proficiency or the high level of English experience alone is not sufficient for enhancing metapragmatic awareness; and (2) English proficiency and experience are important factors in developing metapragmatic awareness among the English language learners.

title: BUILDING A SYNERGISTIC MODEL ON CHEMICAL AND WASTE MULTILATERAL ENVIRONMENTAL AGREEMENTS TO IMPROVE ENVIRONMENTAL ENFORCEMENT : A CASE STUDY OF MULTILATERAL ENVIRONMENTAL AGREEMENTS REGIONAL ENFORCEMENT NETWORK

description: Proliferation of multilateral environmental agreements (MEAs) leads to institutional fragmentation, duplication as well as overloading the national administration and likely causes ineffectiveness of MEAs implementation. Using collective action theory, inter-organization theory and propositions on synergy, clustering, fragmentation and regime effectiveness, this research closely examined a case of MEA Regional Enforcement Network (MEA REN), a pilot project aimed at strengthening enforcement of four chemical and waste related MEAs (Basel/Rotterdam/Stockholm Conventions and Montreal Protocol) in Asia, to prove the claim that building MEAs synergies would improve enforcement effectiveness. The study was conducted through in-depth interview, documentation review, comparing trade data, and qualification analysis. The study concluded that synergy building could improve information flows, inter-agency cooperation, law enforcement operations, capacity building and enforcing licensing system so that countries can enforce MEAs in a more effective way. The study recommended organization reform, enforcement networking and capacity building are key areas to improve enforcement effectiveness, and constructed a model of building synergies for chemical and waste related MEAs to improve environmental enforcement.

title: DEGRADATION OF CHLOROANILINES BY IMMOBILIZED ​ACINETOBACTER BAUMANNII STRAIN GFJ1

description: Chloroanilines are aromatic amines, which have been widely used as ingredients for chemical production including pesticides, dyes and several pharmaceuticals. They are also generated from natural transformation of several herbicides applied into agricultural areas. Thus, they are widely detected in environment, especially in water. Because they are toxic to human and other living organisms and are included in the priority pollutant list, the treatment of these pollutants is necessary. In this study, Acinetobacter baumannii strain GFJ1 isolated from soil was the first pure culture showing its biodegradation ability towards mono-, di- and trichloroanilines as growth substrates. A. baumannii GFJ1 is the first reported bacterial strain that utilized CAs as sources of sole carbon, nitrogen and energy under both aerobic and anaerobic conditions. The determination of the aerobic utilization profile showed that the utilization kinetics followed the Edward model. Under anaerobic conditions, 42.0 ± 4.5% and 32.2 ± 8.5% of 0.1 mM 4CA, and 44.2 ± 0.2% and 28.0 ± 0.3% of 0.1 mM 34DCA were utilized as a growth substrate by A. baumannii GFJ1 with nitrate and sulfate as electron acceptors, respectively, after 20 days. However, the anaerobic utilization of 4CA and 34DCA was significantly lower than that under aerobic conditions. The determination of degradation pathway in A. baumannii GFJ1 showed that the bacteria strain transformed 34DCA to 3CA, 3CA and 4CA was degraded via a modified ortho-cleavage pathway. The 34DCA degradation rates and growth rates of A. baumannii GFJ1 immobilized in beads were significantly higher than freely suspended cells. To enhance the biodegradation rates and mass transfer in the polyvinyl alcohol (PVA)–alginate matrix, pore-forming agents (progens) was used in cell immobilization processes. The addition of CaCO3 and polyethylene glycol (PEG) as porogens into carriers resulted in the changes of bacterial activities. The bead with 10% PVA, 2% alginate and 5% porogen achieved the highest biodegradation rates with 93.6% ± 2.8% of 34DCA degraded after 12 hours, and growth rates among the various tests with different CaCO3 and PEG concentrations. It was found that the addition of the porogens into the carriers increased diffusion coefficient, porosity, pore size and swelling ratio of carriers. The addition of cryopotectants into immobilized gels enhanced cell tolerance during freeze-drying and storage. Among cryoprotectants, glycerol incorporation could effectively sustain 34DCA biodegradation of entrapped cells after 1-month storage at room temperature. The determination of biodegradation of entrapped cells and characterizations of the carrier would provide a method for the design and optimization of the carrier for cell immobilization.

title: LINE-1 HYPERMETHYLATION IN BREAST CANCER STROMAL CELLS

description: Change in methylation level of genes containing Long Interspersed Element-1 (LINE-1) alters host genes regulation. Here we demonstrated paracrine signalling of breast cancer influents the epigenetic regulation of stromal cells. First, we proved by an increased level of genome-wide LINE-1 methylation of laser-captured lymphocytes of metastatic breast cancer lymph nodes. To demonstrate paracrine signaling, in vitro co-cultures between breast cancer cell lines and male or female peripheral blood mononuclear cells (PBMCs) of normal individuals, female fibroblasts or the cervical cancer cell line (HeLa) were set up. Interestingly, LINE-1 hypermethylation occurred exclusively in female PBMCs (P values = 0.0044) or fibroblasts (P values = 0.0288) after co-culture at 4-8 h. No LINE-1 methylation change was observed in co-cultured male PBMCs or HeLa cells. Next, genes containing LINE-1 of breast cancer stromal cells were upregulated. Finally, one of the genes, MUC-1, was validated to have expression in plasma cells from lymph nodes of patients with lymph node metastasis or micrometastasis. In conclusion, breast cancer sends a paracrine signal in stroma cells causing LINE-1 epigenetic regulation. Moreover, the regulated genes in stroma cells are potential biomarkers for detecting breast cancer micrometastasis.

title: PREPARATION OF SILK FIBROIN/ GELATIN/ CHITOSAN BLENDED NANOFIBROUS MEMBRANES TO BE USED AS BARRIER MEMBRANES

description: In this study, various compositions of silk fibroin (SF)/ gelatin (G)/ chitosan (C) in formic acid solutions were electrospun into nanofiber mats. The blending ratios ranged of 10:20:0, 10:20:0.5, 10:20; 1, 10:20:1.5, 10:20:2, and 20:10:1(wt%: wt%: wt%). When the chitosan content in blended solution increased, the average diameter decreased from 280 to 100 nm and fiber sizes distribution was narrow. The formic acid as solvent did not affect the electrospinnability and morphology of SF: G: C blended nanofiber. The appropriate condition of electrospinning process of SF: G: C of 10:20:1 and 20:10:1 blended solution at 20 kV could generate the uniform nanofibers without beads. Tensile strength of SF: G: C (10:20:1) blended nanofiber was decreased with increasing of silk fibroin content, SF: G: C (20:10:1). The nanofiber mats were crosslinked with the vapor of ethanol, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) /N-hydroxysuccinmide (NHS) (EDC/NHS), and glutaraldehyde (GA) for 72 hours, rinsed in distilled water for 30 minutes and then drying in a desiccator at room temperature. It was found that EDC/NHS was able to maintain the original nanofiber morphology after water exposure. It was observed that the SF: G: C at 20:10:1 swelled lower than SF: G: C at 10:20:1. The gelatin effected to swelling of nanofiber mats. The results showed that the EDC/NHS- crosslinked SF: G C (20:10:1) nanofiber mats was selected for the biological testing. In vitro testing of gingival tissues showed good cell adhesion and proliferation. The results indicated that SF: G: C electrospun nanofiber mats could be prepared and have a potential to be applied in barrier membrane application.

title: THEORETICAL INVESTIGATIONS OF THE BIGINELLI REACTION AND THE GLUCOSE TRANSFORMATION TO 5-HYDROXYMETHYLFURFURAL

description: In this thesis, the new insights of the Biginelli reaction, and the glucose transformation to 5-hydroxymethylfurfural have been provided. The obtained most favorable pathways have been purposed without prejudice. Also, the solvent effect in each reaction has been considered. The artificial force induced reaction (AFIR) method was applied to investigate systematically all possible multi-component pathways for the Biginelli reaction mechanism. Among all possible pathways, the most favorable one starts from the C-N bond formation between urea and benzaldehyde molecules, and follows by the nucleophilic addition of ethyl acetoacetate molecule. Surprisingly, an extra urea molecule is catalyzing the reaction nearly every step. Therefore, the Biginelli reaction is a urea-catalyzed multicomponent reaction. The reaction was found identical in ethanol and toluene. For glucose transformation to 5-hydroxymethylfurfural (HMF), RISM-SCF-SEDD method coupled with ab initio electronic structure theory, namely coupled cluster single, double, and perturbative triple excitation (CCSD(T)) has been employed to consider the reaction in both ionic liquid (IL) and water. We found that glucose isomerization in water favored the cyclic mechanism, while open chain mechanism is more favorable in ILs. Besides, the reasonable pathway of the transformation of fructose into HMF is the cyclic mechanism in both IL and water. The decomposition of free energies and radial distribution functions (RDFs) of solute-solvent that are operated by RISM-SCF-SEDD was utilized to clarify the solvent effects of IL.

title: GOVERNANCE CONSIDERATIONS IN FLOOD MANAGEMENT:A CASE STUDY OF NEW ORLEANS

description: The socio-economic disparities, cultural practices, and institutional capacities of New Orleans, Louisiana, U.S. impacted the initial response to Hurricane Katrina in August of 2005, as well as the long-term recovery and present-day mitigation efforts by the local, state, and federal governments. Examining the current practices, perceptions, and future plans of flood management strategies for New Orleans, a city considered to be among those most affected by future climate change impacts, the findings of this report contribute to the identification of the key issues of sustainable urban flood disaster management. The primary method of data collection was semi-structured interviews as the scope of this research concerns the relationship between perspectives of different key stakeholders: (1) community organizers, (2) members of governmental organizations, and (3) representatives of NGOs of flood management in New Orleans. A purposive sampling approach was used to locate a small sample cases with productive, in-depth experiential data required by the nature of the research. Data comprised the statements on organizational roles, capacities, and resources the participants used to express their views and involvement with the issues. The findings show that while New Orleans has clearly defined flood management institutions for high-level flood management capacity, interagency and community cooperation is a key driver to towards the city becoming more resilient to flood disaster. Although the primary strategy for managing future flood disaster continues to be the improvement of the levee system, a modern understanding of the risks from hurricane hazards will be a key factor of the city’s future flood management approach.
