title: A comparison of out-of-class English language learning activities, learning strategies, and attitudes towards autonomous English language learning of English program and regular program students in secondary schools

description: The present study aimed to examine and compare three variables indicating learner autonomy which were out-of-class English language learning activities, learning strategies, and attitudes towards autonomous English language learning of students in English Program and regular program. Furthermore, factors affecting learner autonomy of high and low autonomous learners were investigated. The participants were 499 ninth grade students in English Program and regular program in public secondary schools in Bangkok. A questionnaire and interview questions were used to collect the data. The findings revealed that (1) both English Program and regular program students reported engaging in listening and reading skill activities more often than in speaking and writing skill activities. When comparing the results between two groups, English Program students reported doing English activities outside class more often than regular program students at the significant level of 0.05. (2) Students in both programs reported that they used cognitive strategies most frequently to conduct English language learning activities on their own. English Program students were found to use all learning strategies more often than regular program students at the significant level of 0.05. (3) Both English Program and regular program students were found to have positive attitudes toward autonomous English language learning. However, English Program students seemed to have higher positive attitudes toward autonomous English language learning at the significant level of 0.05. (4) Factors affecting high and low autonomous learners in this present study were found to be intrinsic motivation, metacognitive knowledge about task and strategies, and support from school and family.

title: The emergence and development of Thai contemporary arts and artists : a case study of Thai independent cinema

description: This thesis aims at studying the emergence and development of Thai contemporary arts and artists. It attempts to analyze the cultural politics of emergent arts and artists, Thai cinema in particular, from the aesthetics perspective by using Gramscian theory of hegemony. The analysis reveals that the artists are challenging two notions: the notion of art and the imaginary Thainess constructed in the period of modernization/nation-building. Firstly the study examines that newly emerging Thai artists and their artworks create possibilities to deconstruct conventions of arts in both Thai and international art sphere by using novel and experimental artistic styles and blurring a distinction between art and popular culture. Secondly this thesis examines how it is that the new Thai artists and their artworks challenge Thai hegemony emerged by a narrative of globalization. The study, on one hand, considers that Thai hegemony created by Siamese/Thai elites roots in the mind of Thai artists and its spectators and reflects in their artworks. On the other hand, the new emergent artists and their artworks develop possibilities to challenge Thai hegemony by representing marginalized subjectivities. This study explores how the identity crisis in the globalization era brought about the phenomenon. The thesis looks at the cinematic images of three main concepts; namely Thai national identity, siwilai (or civilized nation) and sexuality by juxtaposing mainstream imageries with the visual and narrative construction in contemporary alternative cinema. The analysis reveals that mainstream filmic works use Thai hegemonic ideas for their expression while independent artists challenge it through alternative portrayals of un-Thainess and the marginal. In filmic representations of Thai national identity, mainstream Thai cinema portrays confrontation between Thainess and un-Thainess and generates nationalistic sentiment while independent filmmakers deal with subjectivities on un-Thainess. Likewise mainstream film portrayals of rural people, ethnic minorities and neighboring countries show their relational views based on degrees of supposed civilization but independent arts represent the subjects more sympathetically. Recent popularity of homosexual subjects in Thai cinema conveys similar tension between mainstream queer cinema, mostly on socially visible transgender and transsexual, from the heterosexual point of view, and independent homosexual-theme films, mostly on gay and lesbian subject matters, focus on their identity and life, which consequently bring homosexuality into the public sphere. The study shows that this group of emergent artists strives to express their identities both aesthetically and politically/socially, and their attitudes toward arts and society bring together like-minds with different backgrounds and form a new community. A community holds the possibility to become a group of intellectuals to challenge against the hegemonic power

title: Anti-inflammatory effects of topical supernatant from human amniotic membrane cell culture after human amniotic membrane transplantation in canine deep corneal ulcer

description: The objective of this study was to examine the effect of topically applied human amniotic epithelial cell (HAEC) culture supernatant on corneal inflammatory reaction in dogs. Twenty five dogs were randomly assigned into 5 groups. The control group consisted of 5 dogs with normal cornea. Inductions of corneal ulcer were performed using 0.45 cm trephine and human amniotic membrane were transplanted in 20 dogs. These 20 dogs were assigned into 4 groups and treated with topical antibiotic, topical corticosteroid, topical mock media and topical culture supernatant from HAEC, respectively. Administrations of the testing agents started at 24 h after transplantation and continued every 4 h for 9 consecutive days. Tear was collected before operation (day 0), 24 h after transplantation, but before application of the testing agents (day1), and day 3, 5, 7 and 9 after transplantation. The concentrations of interleukin-1 beta (IL-1[beta]) and nitric oxide (NO) in tear fluid were measured using canine IL-1[beta] ELISA kit and Griess assay, respectively. Elevations of IL-1[beta] and NO concentrations are associated with inflammatory conditions within the eyes. IL-1[beta] is a major cytokine involved in ocular inflammation and it may induce NO production from many cell types, such as fibroblasts, macrophages and epithelium of the iris-ciliary body. Corticosteroid, a reference anti-inflammatory drug, and the culture supernatant from HAEC significantly decreased IL-1[beta] and NO concentrations. In addition, the clinical signs such as conjunctivitis and neovascularization were improved in both topical corticosteroid and supernatant from HAEC treated groups. Mock and antibiotic solutions failed to decrease NO and IL-1[beta] concentrations. In conclusion, topical application of the culture supernatant from HAEC alleviated inflammation in induced-corneal ulcer of dogs, possibly via inhibition of IL-1[beta] and NO production

title: The effects of a test taker-centered computer-based writing test on Thai first year university students' English writing performance

description: The objectives of the present study were to investigate the effects of facilitative features and required multiple drafts on the writing performance and processes of EFL students in a test taker-centered computer-based writing test (T-CBWT); the computer writing behaviors of the test takers; and the attitudes of the test takers towards the T-CBWT. Subjects were 144 Thai first-year undergraduates of the Faculty of Commerce and Accountancy year 2006. They were purposively sampled and randomly assigned to four equal test groups. Subjects were also classified into three writing proficiency levels using computer-based writing pretest (CBWT) scores as a basis. Research instruments included (1) the T-CBWT, the posttest test with facilitative features allowed and required multiple drafts) (2) analytical rating scales measuring three major aspects of content, organization and language use (3) retrospective questionnaires and (4) stimulated retrospective interview questions. Quantitative data were analyzed via two-way analysis of variance, Kruskal-Wallis H and Mann-Whitney [mu] statistics. Qualitative data were analyzed though textual analysis of test takers’ written drafts, and content analysis of verbal reports and attitudes towards the T-CBWT. Findings from the quantitative analyses in this study seem to provide evidence that facilitative features assist test takers across writing proficiency levels in the improvement of mechanics (spelling and punctuation) but not the overall quality of the essay. In addition, imposed multiple drafts seem to have some influence on the content (topic development & supporting ideas and clarity & explicitness scores) of test takers in the advanced writing proficiency level who were in the ‘with drafts’ test condition. Furthermore, textual analyses reveal that some test takers of the intermediate and low-intermediate writing proficiency levels in the ‘with drafts’ test condition heavily performed content-related changes at the sentence level that were instrumental in improving the overall quality of their essays. These findings together suggest that required multiple drafts and facilitative features might ultimately be effective in assisting test takers in performing their best on a writing test. Findings also indicate that a majority of subjects across writing proficiency levels wrote in a recursive style, confirming established models of writing processes. Finally, test takers in general had a positive outlook towards the T-CBWT and have shown interest in opting to take the T-CBWT again. With further development and research especially in relation to washback, the T-CBWT serves as a potentially practical approach to assess writing and may positively impact the EFL learning and teaching of writing

title: Marginalization as a result of the statelessness of Rom Thai villagers, Mae Ai district, Chiang Mai province

description: This thesis aims to study marginalization as a result of the statelessness of Rom Thai villagers, Mae Ai district, Chiang Mai province. The statelessness of Rom Thai villagers results from having missed the population census and house registration surveys. This study divides the population studied into two groups: the stateless villagers who missed the population census and house registration and who still hold cards for displaced Burmese nationals as their identity cards; and the 1,243 formerly Thai nationals whose nationality was revoked in 2002 and reinstated in 2005. The research finds that both populations studied are still marginalized because they are denied access to the basic rights which are indispensable for human livelihood in three aspects. The right to occupation of the stateless people is restricted by law as well as knowledge and competence of stateless people. The stateless people are not restricted in the right to education and scholarships according to regulations; but in practice, stateless children still do not have access to scholarships as a result of conflicting regulations. Finally, the stateless people are denied national health insurance and have to pay their medical fees in full. Moreover, the stateless people are denied basic health care services from the public health volunteers of the village because they do not have Thai nationality and hold cards for displaced Burmese nationals

title: Mutagenesis of cyclodextrin glucanotransferase gene from Bacillus circulans A11 to change the product specificity of the enzyme

description: Cyclodextrins (CDs) are cyclic oligosaccharides of 6, 7 and 8 glucose units, linked by [alpha]-1,4-glycosidic bonds, called [alpha]-, [beta]- and [gamma]-cyclodextrins, respectively. CDs are the products of enzymatic conversion of starch and related substrates by cyclodextrin glucanotransferases (CGTases), and are useful carrier molecules for several applications in industries. The CGTase consists of 5 domains, A, B, C, D and E. Domains A/B are the central catalytic domain while others perform accessory functions. CGTases that predominantly produce one type of cyclodextrin are of great importance for industry because the costly and time-consuming separation of different cyclodextrins can be avoided. Amino acid sequence comparison of subdomain A2 between the Bacillus circulans A11 [beta]-CGTase and the [alpha]- and [gamma]- CGTases, four different regions I, II, III and IV were found at position 239-250, 262-271, 284-320 and 333-342 (B. circulans A11 CGTase numbering), respectively. In addition, S184, E264 and E268 were also selected to study the mode of substrate entrance. The four regions as well as S184, E264 and E268 in [beta]-CGTase from Bacillus circulans A11 were mutated using the unique site elimination (USE) mutagenesis method. The dextrinizing activity and CD-forming activity of the mutant enzymes were assayed. It was found that region I mutation had no influence on product specificity, regions II and III favored [beta]-CD production, and region IV showed little affect on [beta]-CD production. The S184K mutation slightly increased the proportion of [alpha]-CD with the expense of [gamma]-CD.

title: Simultaneous data reconciliation and gross error detection using a robust function method for nylon 6 reactor

description: On-line optimization is a powerful method for economic improvement and resource reduction in chemical industries, because it allows a process to be operated near its optimum operating condition.Thus, it is currently receiving increasing attention. In order to perform online optimization, sequence solving of three optimization problems which are data reconciliation, parameter estimation, and economic optimization are required. Normally, process measurements are used to determine the actual state of the process. However, these measurements usually contain random as well as gross errors. Both random and gross errors should be eliminated in data reconciliation step. Further, the reconciled data must satisfy process material and energy balances. In this work, we apply data reconciliation in VK column reactors for industrial nylon 6 production process at steady state condition. Three data reconciliation algorithms: Contaminated Normal, Lorentzian distribution function and Hampel’s redescending M-estimator, are investigated to compare the performances. We also compare these algorithms under the conditions where some process streams are unmeasured. The result shows that all algorithms perform well in this process. Because it can support with process measurements contain both gross and random errors. Moreover, these algorithms also work well in the case where unmeasurement process streams exist.

title: Bioactive compounds from endophytic fungi from Suregada multiflora (A. Juss.) Baill.

description: In this study we isolated bioactive compounds from the endophytic fungus isolate SM1 from a bark of Suregada multiflora (A. Juss.) Baill. Crude extract from the YES culture broth of endophytic fungus isolate SM1 was purified by chromatographic techniques to afford two compounds, which were identified as 2-phenylethanol, and 4-methyl-5-oxo-2-propyl-tetrahydro-furan-3-carboxylic acid. The chemical structures of isolated compounds were elucidated through extensive analyses of UV, IR, MS, and NMR spectroscopic data and by comparison with literature. The isolated compounds showed no antimicrobial activity, antimalarial activity, and anticancer activity. Based on morphology and nucleotide sequence of ITS1-5.8S-ITS2 regions of rDNA, the endophytic fungus isolate SM1 was identified as Lasiodiplodia sp., possibly an anamorph of Botryosphaeria rhodina (100 % sequence homology).

title: DNA fingerprint analysis of stemona in Thailand

description: In Thailand many species of Stemona were reported and biological activities such as insecticide, insect repellency and anti-tumor were different. Thus, accurate identification of Stemona is needed in order to ensure their efficacies. The identification based on morphological characters of each species alone is difficult because the morphology of Stemona is similar and they are often sold as crude drug which lose their original feature. The purpose of this study was to analyze DNA fingerprint of six Stemona in Thailand; S. tuberosa Lour., S. collinsae Craib, S. phyllantha Gagnep., S. burkillii Prain, S. aphylla craib and Stemona sp., and developed PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) as a genetic marker in order to use as a convenient tool for identification. The nucleotide sequences of three DNA regions; matK, trnH-psbA and ITS1, were exploited to identify these six Stemona species in Thailand. A result of the comparison of partial matK could be classified Stemona into two groups, S. tuberosa group and S. collinsae group, concerning with their morphology and chemical composition. The nucleotide sequences of trnH-psbA and ITS1 could be used to discriminate six Stemona spcies in Thailand. On the basis of difference among the partial matK gene and ITS1 region, the PCR-RFLP analysis was performed. The restriction patterns showed distinct and polymorphic fingerprints among Stemona spp. and were able to apply for crude drug identification. These results exhibited that the obtained nucleotide sequences could be used to identify Stemona in Thailand. PCR-RFLP genetic marker developed here could be used as a convenient tool for authentication of Stemona and also be applied to their commercial crude drugs

title: The relationship between pharmacokinetic parameters of phenytoin and carbamazepine in epileptic patients

description: Objective: Phenytoin (PHT) and carbamazepine (CBZ) are commonly prescribed together for treatment of epilepsy in patients who cannot control seizures with single drug. Both drugs are mainly metabolized via cytochrome P450, it is therefore possible that their pharmacokinetic parameters would be related. This study was designed to determine the correlation between pharmacokinetic parameters of the two drugs and provide regression equations to predict pharmacokinetic parameters of PHT from CBZ, and vice versa. Moreover, this study was also designed to compare the maximum rate of metabolism of phenytoin (Vmax) and carbamazepine clearance (ClCBZ) when used as a monotherapy with those obtained from incombination therapy. Method: A retro-prospective observational pharmacokinetic design was performed in 48 epileptic patients. They were categorized into 3 groups: PHT-CBZ combination therapy group, PHT monotherapy group and CBZ monotherapy group. One blood sample was collected from each patient at steady state condition. Serum drug concentrations of both drugs were determined. Vmax and ClCBZ were calculated, correlation coefficients and regression equation were performed. Comparisons of Vmax and ClCBZ between monotherapy group and combination therapy group were also determined to evaluate the pharmacokinetic interaction between two drugs. Results: There was a significant linear correlation between Vmax and ClCBZ (r=0.828; P = 0.001). Vmax between monotherapy group and combination therapy group were not significantly different (362.80 ± 51.78 and 331.64 ± 71.93; P = 0.170) while ClCBZ were significantly different (105.35 ± 35.45 and 76.45 ± 26.62; P = 0.014) between monotherapy group and combination therapy group. Conclusion: Vmax could be accurately predicted from ClCBZ and vice versa. This would save cost for patients.
