title: A study of language learning strategies of students in an english program in Thai secondary school

description: The purpose of this study is to investigate the use of language learning strategies of students in an English program in a Thai secondary school. The subjects of this study were thirty students in Grade 7 in an English program, selected using a purposive sampling method. Data were collected by means of a questionnaire and a focus-group interview. Data analysis consisted of descriptive analysis to find means ( x ) and standard deviation (SD.) and content analysis for data collected from the focus-group interview. The research findings showed that students employed most of the language learning strategies at a moderate level, with a few at a high level. Each of the strategies reported were used with different frequency because students’ learning styles, learning preferences, learning activities, and learning problems were different. Therefore, it can be concluded that students choose language learning strategies that they think are the most suitable for their needs to improve their own language skills. Thus, teachers should realize these factors and apply it to classroom teaching to help students improving their own language skills.

title: Impacts of the Republic of Korea foreign direct investment on the development of CLMV

description: Foreign Direct Investment (FDI) brings the critical development in host countries’ infrastructures such as public utility, information technology and transportation systems. FDI also improves their people’s income and living standard. Because of above mentioned benefits, many countries have continuously put efforts to attract FDI. CLMV, consisting of Cambodia, Lao, Myanmar, and Vietnam, has struggled to attract FDI and due to their plentiful natural resources, lower manufacturing cost, and market opportunity, they have attracted FDI from many countries. Korean FDI in CLMV is increasing and has been recently ranked top. This study has objectives to determine the factors of the growth in gross domestic products by means of linear regression and analyze causality between the growth of Korean FDI and other factors by means of Granger Causality test, using panel data (comprised of time series data and cross sectional data). The results showed that the growth of Korean FDI significantly boosted the growth of Vietnam’s GDP. The granger causality test affirmed that the growth of Korean FDI to CLMV affects their GDP growth only in the first year. Finally, this study affirms the effectiveness of Korean FDI in CLMV.

title: Palaeontology of the early cretaceous non-marine molluscan assemblages from the Sao Khua formation in Nong Bua Lamphu, Phu Wiang and Sahat Sakhan areas, Northeastern Thailand

description: Sixteen taxa of freshwater mollusan assemblages from 16 shell beds at 12 localities in Nong Bua Lamphu, Phu Wiang and Sahat Sakha Areas were studied. They were subdivided into 4 assemblages, including, Koreanaia (Eokoreanaia) sp. - Yunnanoconha sp. Assemblage, Yunnanoconcha sp. cf. Y. khoratensis Assemblage, Pseudohyria (Matsumotoing) somanai - Trigonioidoidea fam. indet. Assemblage and incertae cedis (4) Asseblage. Koreanaia (Eokoreanaia) sp. - Yunnanoconcha sp. Assemblage was discovered only in Huai Lao Yang Fossil Locality, near the boundary between the Sao Khua Formation and the underlying Phra Wihan Formation. The assemblage is related to mudstone and siltstone, and can be related to Hauterivian - Barremian Nippononaia (Eonippononaia) tetoriensis - Koreanaia (Eokoreanaia) cheongi - Danlengiconcha elongata Assemblage of East Asia. Yunnanoconcha sp. cf. Y. khoratensis Assemblage is reated to mudstone and siltstone. Yunnanoconcha sp. cf. y. khordtensis possesses their morphlology and size as intermediate form between Yunnanoconcha sp. and Yunnanoconha khoratensis of the khok Kruat Formation. Pseudohyria (Matsumotoina) somanai - Trigonioidoidea fam. indet. Assemblage is widely distriuted in sandstone and conglomeratic sandstone of the Sao Khua Formation. Pseudohyria (Matsumotoina) somanai Tumpeesuwan, Sato & Nakhapadungrat, 2010 was proposed as new species and firstly reported of the subgenus Pseudohyria (Matsumotoina) in Thailand. This subgenus is restricted to Late Barremian of Japan and Korea. This evidence might be suggested Late Barremain age for the Upper part of the Sao Khua Formation. incertae cedis (4) Assemblage was discovered only in 3 shell beds of Phu Wiang Areas. This assemblage is related to conglomeratic sandstone. Hinge teeth and muscle scars of incertae cedis (4) are not preserved on the molds; therefore, exact identification is impossible. Based on the evidences of molluscan assemblages, Hauterivian - Early Barremian and Late Barremian Ages were assumed for the lower and upper parts of the Sao Khua Formation, respectively.

title: Determination of equivalent lightness of small stimulus in the elderly using cataract experiencing goggles

description: The research aims to obtain and to improve the equivalent lightness perceived by elderly people by using the cataract experiencing goggles. Two viewing conditions were employed, the normal viewing and the environment-stimulus independent condition. In the normal viewing condition the heterochromatic brightness matching was carried out for four colored stimuli under nine illuminance levels from 0.08 lx through 800 lx. The results showed the equivalent lightness was lower with the goggles by the amount about 10 L* unit at any illuminance level. The color appearance experiment was also carried out by the elementary color naming method, where the chromaticness, whiteness, and blackness were estimated for colored stimuli. The chromaticness decreased for lower illuminance causing the equivalent lightness to decrease. The environment-stimulus independent condition was proposed to keep the equivalent lightness of elderly people high. A colored stimulus was placed in a separated room from the subject room and its illuminance was kept constant as 200 lx, while that of the subject room was varied as in the normal viewing experiment. By this way the effect of the environment light was reduced. The result showed that the equivalent lightness was high even with goggles for all the room illuminance unlike the normal viewing condition. It was found from the two experiments that the equivalent lightness of elderly people was composed of L*achr, L*chr, and L*env.

title: Women directors, network and firm performance in Thailand

description: This study focuses on the impact of female directors on firm performance in Thailand. The network between female directors and firm shareholders or board members are detected and tested against firm performance. The sample of this study is firms listed on Stock Exchange of Thailand (SET) during the year 2000- 2009. In a sample of Thai firms, I find that the trend of having female directors in boardroom is flat. The pattern of gender composition or percentage of board seats held by female in boardroom is constant overtime. From this study, I show that female directors have a significant impact on firm performance. In general, female directors in boardrooms have negative impact on firm performance. Nevertheless, female directors help improve performance in firms that are classified as busy firm which normally have significant negative impact on firm performance. This result suggests that gender-diverse board allocate more effort to monitoring. Moreover, female directors who have family network with high control majority shareholders have significant positive impact that help improve firm performance. Also, Female directors who have alumni network add value to firm. The results suggest that the network or connection can be viewed as the effective tool that, in some way, bring value and help firm to enhance firm performance.

title: Effects of selected Thai ancient remedies extracts on mutagenicity and antimutagenicity using Ames test

description: The extracts of selected Thai household ancient remedies namely, Chantaleela, Prasachandang, Keawhom, Treehom, Ummalukkawatee, Prasamawaeng, Wisampayayai, Thoraneesantakat and Homtip-osot were determined the mutagenicity and antimutagenicity effects in the absence of metabolic activation using Salmonella typhimurium TA98 and TA100. It was found that most ethanolic and water extracts of selected Thai ancient remedies in treating without nitrite were not directly mutagenic, except that the ethanolic extract of Treehom exhibited mutagenicity. The mutagenic index of ethanolic Treehom extract was 3.64 and 2.21 on Salmonella typhimurium TA98 and Salmonella typhimurium TA100 respectively. However, after treating with nitrite, all extracts showed the mutagenicity against both strains. It was demonstrated that the ethanolic and water extracts of Thoraneesantakat showed the highest mutagenic index on TA98 and TA100. Furthermore ethanolic extracts seemed to be more mutagenic than water extracts. The antimutagenicity of Thai ancient remedies extracts against the product of the reaction mixture of 1-aminopyrene-nitrite model in the absence of metabolic activation. The results showed ethanolic of Wisampayayai remedy (10mg/plate) showed the highest antimutagenicity on TA98 (155%) and ethanolic of Chantaleela remedy (15mg/plate) showed the highest antimutagenicity on TA100 (107%).

title: The pattern of binge drinking among young adults in high socioeconomic nightclubs, Bangkok

description: This study investigated the pattern of binge drinking among young adults in high socioeconomic area. Total 348 respondents were passed the screening test of AUDIT within 8-19 score of binge level. Males were more likely to have harmful drinking than females as males were more likely to drink more than females, as males were more likely to drink than females. People who binge drinking around high socioeconomic area has moderate to wealthy status and finished at least Bachelor degree. The respondents who earned high income were more likely to drink more volume of alcohol, and tended to spend more on their binge drinking; especially males were found to spend higher than females. Beer (68.8%) was the type that males consumed the most in past 30 days, while wine (64.6%) was the most in females. Selling alcohol (94.3%) and location (95.1%) showed the majority that encouraged the respondents to nightclubs. Influenced by friend (95.1%) were also the major elements in development of binge drinking problems. Many of the respondents experienced alcohol-related consequences such as unable to continue regular routine (81.9%), accidents (42.8%), and unprotected sex (42.5%). The chance created these consequences had increased by the higher volume of alcohol consumption. There was the high number of illicit drug used, as males have ever consumed more drugs comparing to females. The number of respondents who consumed Cocaine (38.5%), Erimin5 (28.4%), and Ecstasy (25.3%) were popular in nightclubs. Some of the respondents admitted that they paired drugs with alcohol, as Cocaine (33.3%) was the highest, following with Ecstasy (25.9%), and Erimin5 (24.4%) respectively. The study found that binge drinking in high socioeconomic nightclubs was considerably high, and affected to health consequences. The related organization should be surveillance, and plan for the future prevention and intervention.

title: Maintaining the union of Burma : the role of the ethnic nationalities in a Shan perspective between 1946-1962

description: This thesis seeks to re-examine the period 1946-62 from the viewpoint of the ethnic nationalities, using a Shan perspective with an emphasis on trends in Shan State. Some examination is made of the drafting of the constitution, the federal system and the federal movement of the early 1960’s. Finally, the idea of national ‘unity’ is reconsidered as a factor in the failure of the ‘Union of Burma’ of this period. This paper ultimately contends that the nation which won independence in 1948 was unlike any political entity that had previously existed in the region. The legitimacy of the new government’s rule was not based on hereditary kingship, ultimate moral authority or divine right, but supposedly on its adherence to the rule of law and constitutionality. This new ‘nation’ was new for all its members and the political complexities of British administration in maintaining a separate Burma proper and Frontier Areas were not adequately discussed or considered when the inhabitants of these two areas proposed to join to form a Union. Different political ideologies meant that leaders from various parts of the new country and representatives of different groups sometimes disagreed strongly later on. During the precarious early years of independence and consistent revolt, the initially weak central government relied heavily on the military to assert state control. The growth and extent of the army’s sometimes oppressive control led to discontent in many former border areas. As political solutions to central government failure seemed ineffective, armed resistance grew. State governments had to contend with rebels in their own territories as well as aggressive Burma Army forces. The politicization of the military led to a diffusion of ideas that minority groups, by virtue of being minorities, were synonymous with rebellion and disunity.

title: Vague prime ideals and vague primary ideals of vague rings

description: A vague binary operation on a set X with respect to [a fuzzy equality on X] x X and [a fuzzy equality on X] is a strong fuzzy function õ with respect to [a fuzzy equality on X] x X on X x X and a fuzzy equality [a fuzzy equality on X]. Moreover, a vague ring with respect to E [subscript H x H] and E [subscriptH] defined in 2007 by Sezer is a 3-tuple [a vague ring] satisfying some certain conditions. Vague ideals and vague prime ideals were defined in 2007 by the same author. In this thesis, we present vague primary ideals and some elementary properties of vague prime ideals, vague primary ideals and their related vague ideals. In addition, we give the sufficient condition of the vague ring of matrices to have no vague prime ideals. Eventually, we give some sufficient conditions which vague prime ideals, vague primary ideals and some related vague ideals are coincide.

title: Effect of noise block using earplugs on propofol sedation requirement during extracorporeal shock wave lithotripsy

description: Objective: To determine effect of noise block using earplugs on reducing propofol infusion needed to maintain a constant bispectral index (BIS) values in patients undergoing extracorporeal shock wave lithotripsy (ESWL). Design: Randomized double- blinded controlled trial. Material and method: Fifty-eight patients (18-65 years) with nephrolithiasis undergoing ESWL, having ASA physical status I or II and have normal hearing function tested by audiometry were enrolled in this randomized, double-blind, controlled trial. Patients were randomized and allocated into two groups: noise blocked group (earplugs inserted into both ears) and control group (earplugs not inserted). Sedation by target-controlled infusion was started with 1.2 mcg/mL of propofol and propofol target concentration was adjusted gradually by 0.2 mcg/ml every 5 minutes intraoperatively to achieve and maintain bispectral index (BIS) values within 75-80% until the procedure finished. Total amount of propofol (mg), BIS values (%), ambient noise level (dB) and patient satisfaction (1-5) were measured. Results: The amount of propofol infusion needed to maintain a constant BIS index value in patients undergoing ESWL in the noise blocked group was significantly lower than that in the control group (6.91+2.05 vs 8.23+2.16 mg/kg/m2/hr, p=0.021, 95%CI=0.21-2.42).Patient satisfaction was similar in both groups (4[1] vs 4[1], p=0.929). Conclusion: Noise elimination in ambient operating room can reduce the amount of propofol needed to maintain light sedation during ESWL.

title: Development of a reading instructional model using the 4MAT system and music to enhance vocabulary acquisition for English reading comprehension and attitude towards learning of undergraduate students

description: The purposes of this research were 1) to develop the reading instructional model using the 4MAT System and music to enhance vocabulary acquisition for English reading comprehension and attitude towards learning of undergraduate students and 2) to investigate the effectiveness of the reading instructional model using the 4MAT System and music to enhance vocabulary acquisition for English reading comprehension and attitude towards learning of undergraduate students, which was done by comparing vocabulary ability, English reading comprehension, and attitude towards learning of the students instructed through this model with those who learned through conventional instruction. The samples of this research were purposively selected 60 second-year English majors of the Faculty of Liberal Arts, Rangsit University, who had enrolled in the course: Reading I during the second semester of the academic year 2010. They were divided into 30 for control and another 30 for experimental groups equally. Based on the pre-test post-test control group design, the study covered the period of 10 weeks. The data collecting instruments were vocabulary ability test, reading comprehension test, and reading attitude questionnaire. Data were analyzed by the percentage of average score, standard deviation, and t-test. The findings of this research were as follows: 1. The developed instructional model, aiming to enhance vocabulary ability and reading comprehension, and to promote positive attitudes towards reading, consisted of five principles: 1) Learners expand and reﬁne information through adaptive modes by interacting with them, 2) Students need multiple exposures to new inputs in order to understand them, 3) Reflections the students have on their expression and learning must be shared and turned around, 4) Students should actively make connections between the new and the known, 5) The integration of background music maximizes learning and enhances reading attitudes. The model incorporated six instructional steps: 1) Recalling Experience, 2) Imagining, 3) Explicit Modeling, 4) Reading with Music, 5) Parallel Practicing, and 6) Sharing Outcome. 2. The results of the evaluation of the effectiveness of the developed instructional model indicated that: the experimental group had significantly higher vocabulary ability post-test mean scores than the control group at the level of 0.05, 2) the experimental group had significantly higher reading comprehension post-test mean scores than the control group at the level of 0.05, and 3) the experimental group had significantly higher mean scores of attitude towards reading than the control group at the level of 0.05.

title: Oxidation of glycerol using polymer-supported IBX

description: A new polymer-supported IBX was prepared in this research to use as an oxidizing agent in the oxidation reaction of glycerol. The appropriate method for the synthesis of polymer-supported IBX consisted of 8 steps using p-toluic acid as a starting material for IBX and aminomethyl polystyrene as a supporting material. For the synthesis of aminomethyl polymer-supported IBX, a new process for oxidation of C-H bond of 3-iodo-4-methylbenzoic acid was discovered. This oxidation using sodium hypochlorite (NaOCl) as an oxidant gave higher conversion than using sodium periodate (NaIO4) as an oxidant. The new polymer-supported IBX was used to oxidize benzyl alcohol and glycerol and its oxidation was also compared with IBX (1), DMP (2), aminomethyl polymer-supported IBX amide (3), N-phenyl-2-iodoxybenzamide (4), and N-phenyl-3-iodoxybenzoic acid (5). Benzyl alcohol was oxidized with IBX (1), DMP (2), aminomethyl polystyrene-supported IBX amide (3) and aminomethyl polymer-supported IBX amide (6) as oxidizing agents while glycerol was not oxidized by those oxidizing agents.

title: Gene expression analysis and anti-WSSV property of antimicrobial peptides from the black tiger shrimp Penaeus monodon

description: Antimicrobial peptides or AMPs are small peptides which play an important role in the innate immune system by defending against invading microorganisms. The crustin, lysozyme, antilipopolysaccharide factor (ALF), and penaeidin (PEN) are AMPs identified from the Penaeus monodon EST database (http://www.pmonodon.biotec.or.th). Analysis of the P. monodon AMP transcripts by semi-quantitative RT-PCR revealed that the expression of ALFPm3, ALFPm6 and PenmonPEN5 was significantly increased after shrimp were challenged with white spot syndrome virus (WSSV). In this study, we further characterized PenmonPEN5 for its role in anti-WSSV. Genomic organization of the Penmon PEN5 gene determined by PCR and genome walking revealed two exons interrupted by an intron, while the 5´ upstream sequence contained a putative promoter, TATA box, and regulatory sequences, three GATA, and two each of GATA-3, activator protein 1 (AP-1) and dorsal transcription factor binding. These cis-regulatory elements are reported to be involved in the transcription of several arthropods antimicrobial peptide genes. The PenmonPEN5 mRNA was mainly expressed in shrimp hemocytes and was up-regulated about 1.8 fold at 24h after challenge with WSSV as detected by quantitative real-time RT-PCR. The suppression of PenmonPEN5 transcript levels by RNA interference mediated gene silencing led to an increase of WSSV copy numbers about 1.9 fold. The recombinant PenmonPEN5 protein (rPenmonPEN5) over-expressed in the yeast Pichia pastoris exhibited antibacterial activity against Gram-positive bacteria, Micrococcus luteus and Aerococcus viridans. Incubation of the P. monodon hemocyte primary cell culture with the mixture of WSSV and rPenmonPEN5 inhibited the propagation of WSSV only at 6.25μM but not at higher concentration of the protein. Taken together, the results suggest a possible role of PenmonPEN5 in the shrimp’s antiviral immunity but its defense mechanism requires further investigation.

title: Spin sensitive variables for the products of supersymmetric particles

description: Supersymmetry (SUSY) is a possible extension of the Standard Model, which predicts that each Standard Model fermion has a boson superpartner and each Standard Model boson has a fermion superpartner. The search for supersymmetry is one of the main topics for study with the Compact Muon Solenoid (CMS), a general purpose detector at the Large Hadron Collider (LHC) at CERN. In this thesis, particle spin measurement are studied through effects in angular correlations in the decay products of supersymmetric particles. A Lorentz invariant quantity, the invariant mass of decay products, has been used to build asymmetries to investigate these correlation effects. Two different supersymmetric decay chains, namely the decay of a squark via a neutralino-2 and the decay of a stop quark (partner of top quark) via a chargino-1, have been used as examples for this study We conclude that we can expect to extract spin information from the sparticles. The required amount of data depends on the supersymmetric particle mass spectrum. We have studied several final states, in order to have several measurements for the spin characterization of the supersymmetric paticles
