title: Perceptions and health behaviors toward avian influanza among backyard poultry farmers at Suantaeng sub-district, Muang district, Suphan Buri province

description: The purpose of this study was to explore perceptions and health behaviors toward Avian Influenza among backyard poultry farmers at Suantaeng Sub-District, Muang District, Suphan Buri Province. Backyard poultry farmers (n = 172) were recruited by simple random sampling. The data were collected from July 2007 to August 2007. Perceptions and health behaviors were analyzed as number, percentage, levels and relationship by Pearson's Product Moment Correlation Coefficient. The results were illustrated; 1) The samples' perceptions were at a moderate level 72.7%, with a range from 34.3 to 40.1 scores (Mean = 37.2, S.D. = 2.9). 2) The samples' health behaviors were at a fair level 70.3%, with a range from 13.3 to 18.7 scores (Mean = 16.0, S.D. = 2.7). 3) There was no significant relationship between perceptions and health behaviors (r = 0.1, p = 0.2). These findings suggest that the Ministry of Public Health should be implemented to develop preventive health behavior guidelines toward Avian Influenza such as "how to; avoid touching secretion of native chicken; raise safely free range mode and use the chop (avoid to use the same chop)".

title: Predicting issuer rating change and standard of rating agency : empirical evidence in G7 except US

description: Researchers have been forecasting ratings change for decades, most of them have estimated single-period classification model, which is static model with multiple-period ratings change data by neglecting the fact that firms change through time. Therefore, a new model, hazard rate model, is proposed (Shumway 2001). Theoretically, hazard rate model is more appropriate than static model for forecasting since hazard rate model explicitly considers the time-varying of both ratings and firms’ characteristics. The purpose of this study is to compare the accurate performances on predicting issuer ratings change between using static and hazard rate models. Empirical results indicate that hazard rate model outperforms static models in out-of-sample forecasts. Moreover, there were distress failures of great companies even though they had investment rates leading some to conclude that these collapses occurred because of accounting fraud and corruption. However, alternative explanation of these failures is that the rating agencies are now using softer standards in assigning ratings. This study examines standard of rating agency by employing ordered logit model and results suggest that rating standards are lenient. Therefore, the failure of great firms in the past can be partly explained by the softer standa.rd of rating agency.

title: Preparation and controlled release of poly (lactide-co-glycolide) containing nicotine

description: Nicotine replacement therapy is widely used to treat nicotine withdrawal during smoking cessation. Nicotine transdermal patches, easily used by patients, can however cause swelling and itching in the area covered by the patch. These symptoms are perhaps caused by non-biocompatible adhesive material used in patches. To eliminate this problem, biomaterial for example, poly(L-lactic-co-glycolide) (PLLGA) was used in the preparation of controlled released nicotine transdermal patches in this study. Low molecular weight of poly(L-lactic acid) (low MW PLLA) was prepared by condensation polymerization of lactic acid. L-lactide was synthesized from thermal decomposition of low MW PLLA, Later, PLLGA copolymer was prepared by ring opening polymerization (ROP) of L-lactide and glycolide using different L-lactide and glycolide molar ratios. The effects of type and concentration of catalyst, polymerization time, temperature and molar ratio of L-lactide and glycolide were studied. Poly (vinyl alcohol) PVA was used in preparation with PLLGA copolymer film. It appears that the ratio of 0.5PLLGA/2PVA and 1.5PLLGA/2PVA at the L-lactide/glycolide copolymer molar ratio of 70/30 provided the minimum and maximum nicotine release of 738 and 5,072 ugcm-2h-1, respectively. The PLLGA blended PVA film containing 0.5PLLGA/2PVA at the L-lactide/glycolide copolymer ratio of 70/30 has the amount of nicotine release similar to that in marketed transdermal patch. Therefore it is suitable to be used in people who would like to stop smoking.

title: Pseudometrics for time series data classification using the nearest neighbor algorithm

description: We propose that pseudometric, a subadditive distance measure, has sufficient properties to be a good structure to perform nearest neighbor pattern classification. There exist some theoretical results that asymptotically guarantee the classification accuracy of k-nearest neighbor when the sample size grows larger. These results hold true under the assumption that the distance measure is a metric. The results still hold for pseudometrics up to some technicality. Whether the results are valid for the non-subadditive distance measures is still left unanswered. Pseudometric is also practically appealing. Once we have a subadditive distance measure, the measure will have at least one significant advantage over the non-subadditive; one can directly plug such distance measure into systems which exploit the subadditivity to perform faster nearest neighbor search techniques. This work focuses on pseudometrics for time series. We propose two frameworks for studying and designing subadditive distance measures and a few examples of distance measures resulting from the frameworks. One framework is more general than the other and can be used to tailor distances from the other framework to gain better classification performance. Experimental results of nearest neighbor classification of the designed pseudometrics in comparison with well-known existing distance measures including Dynamic Time Warping showed that the designed distance measures are practical for time series classification.

title: Removal of basic dyes using green macroalga caulerpa lentillifera

description: A macroalga Caulerpa lentillifera was found to have high adsorption capacity for basic dyes. For the sorption of a basic dye Astrazon® Blue FGRL, the adsorption reached equilibrium within the first hour for whole range of concentrations employed in this work (20-1,280 mg l-1). The kinetic data corresponded well with the pseudo second-order kinetic model where the rate constants decreased as initial dye concentrations increased. At low dye concentrations (20-80 mg l-1), an increase in the adsorbent dosage resulted in a higher removal percentage of the dye, but a lower amount of dye adsorbed per unit mass (q). The adsorption isotherm followed both the Langmuir and Freundlich models within the temperature range of 18-70oC. The highest maximum adsorption capacity (qm) was obtained at 50oC. The enthalpy of adsorption was estimated at 14.87 kJ mol-1 suggesting a chemical adsorption mechanism. The results were compared to the sorption performance of a commercial activated carbon. The comparison studies were done using 3 basic dyes, i.e. Astrazon® Blue FGRL, Astrazon® Red GTLN, and methylene blue. The evaluation revealed that the alga exhibited greater sorption capacity than activated carbon for all types of basic dyes. Further investigation showed that the sorption process obeyed the pseudo second order kinetic model. The sorption processes were controlled by both film and pore-diffusion. BDST and Thomas models were used to analyze experimental data from continuous flow study and the model parameters were evaluated. Good agreement of experimental results on breakthrough characteristics with the model prediction was observed. In the study of binary dye mixture, shifts of spectral peaks were observed when the composition of the mixture changed and the area beneath the light absorbance curve corresponded to the quantity of the dyes in the mixture. Then the new, simple analytical method was proposed for the measurement of individual dye component in the mixture of two dyes.

title: Reporter gene silencine by production of hairpin RNA in Tobacco Nicotiana tabacum L.

description: RNA interference (RNAi) is a post-transcriptional gene-silencing phenomenon induced by double-stranded RNA (dsRNA) molecules that contain nucleotide sequences complementary to target mRNA sequences causing degradation of the latter. It is an effective approach in inhibiting expression of a target gene for gene function analysis. Here, transgenic tobacco plants in which a β-glucuronidase (gus) gene was silenced were generated by introducing a gus hairpin (hpGUS) sequence into a transgenic tobacco (Nicotiana tabacum L. cv. Virginia Coker) harboring a gus gene by Agrobacterium-mediated transformation. Then, transgenic tobaccos were selected on MS media containing kanamycin. All putative independent lines were confirmed by PCR amplification for the presence of the hpGUS construct using their genomic DNA as template. Three independent lines of the hpGUS-expressing double transfomants were obtained from the regeneration of kanamycin-resistant cells and confirmed by Southern blot analysis. Northern blot analysis showed silencing of the gus transcript in all independent lines as compared with the control plants. The reduction of gus mRNA level was confirmed by histochemical and spectrophotometric GUS assay. GUS activity of the hpGUS-expressing double transfomants was lower than the control double tansformants indicating that hpGUS can silence expression of the gus gene at the protein level.

title: Risk factors of running injuries middle-age to elderly Thai joggers

description: Running is one of the most popular leisure sport activities. Besides its beneficial health effect, negative side effects in terms of sports injuries should also be recognized, especially middle-age and elderly people. The purpose of this study was to identify risk factors of running injury in middle-age to elderly joggers and to determine the incidence of running injuries. Running related injuries were prospectively monitored in 250 Thai joggers, aged 45-75 years for middle-age to elderly subjects for 16 weeks. The Questionnaire was used to collect data as follows; characteristics of subjects, jogging profile, and running injuries profile. Additionally, the measurement of static lower-limb alignment (Q-angle, leg-length discrepancy, arch type). Logistic regression model assessed the relative contribution of the predicted risk factors. Most subjects were male (90.4%), aged 53.5 +- 6.39 years. After logistic regression analysis found that male (OR 3.801; 95%CI 1.279 to 11.292), arch type (Low arch) (OR 5.811; 95%CI 1.238 to 27.273), holding time of each stretch (&lt; 15 sec vs. &gt; 30 sec per stretch) (OR 2.734; 95%CI 1.166 to 6.409), previous injuries (OR 9.996; 95%CI 4.974 to 20.088) were associated with running injuries. The incidence of running injuries was 48.4% and the knee (46.6%) was the most commonly injured site. In conclusion, previous injuries were the greatest risk factors for running injuries in this study, followed by arch type, holding time of each stretch, and sex respectively.

title: Synthesis and properties of new calix[4]arene containing diacetylene pendants

description: Topological polymerization required specific supramolecular assembly of the monomer molecules that can provide unique structures of polymer can not be attained by conventional polymerization. The best known topological polymerization to date involves diacetylene monomers to produce the corresponding ene-yne conjugated polydiacetylenes. The new series of tert-butylcalix[4]arene derivatives containing 2-4 diyne chains on the phenoxy rim were synthesized in this dissertation in the attempt to demonstrate the first polymerization through a topological intramolecular 1,4-addition of diyne. The copper-catalyzed coupling reaction of multipropynyl-tert-butylcalix[4]arene with 5-iodo-4-pentynol in pyrrolidine constitutes the key step in the synthesis of the diynes chain. The solid-state photopolymerization study indicates that only the calix[4]arene derivatives containing four diyne units with alkyl urethane groups can be topologically polymerized to afford polydiacetylenes containing calix[4]arene. The length of alkyl linker between the diyne and carbamate group also has a pronounced effect on the polymerizability of the diyne units. The visible absorption band at 350-600 nm and the Raman signals around 1500 and 2100 cm-1 signified the ene-yne conjugation of the resulting polymers. The polydiacetylenes obtained displayed the formation of nanodisk in water and tetrahydrofuran probably through a micelle type self-assembly. The polymers also exhibited reversible red to yellow thermochromism near 120 ºC.

title: Synthesis of light olefins from methanol on co/zsm-5 catalyst

description: This research focused on investigation on characteristic and catalytic properties of H/ZSM-5 and Co/ZSM-5 zeolite catalyst used for methanol conversion. In fact, four of H/ZSM-5 zeolite catalysts having different Si/Al ratios (20, 50, 80 and 150), were synthesized by hydrothermal method. Those catalysts were tested in various reaction temperatures ranged between 200-500 0C in order to select the suitable Si/Al ratio and reaction temperature. Base on light olefin yield, it was found that the H/ZSM-5 zeolite catalyst at Si/Al of 80 was the suitable catalyst at 300 0C reaction temperature for methanol conversion into light olefins. In addition, three of H/ZSM-5 zeolite catalysts, having different particle sizes (1.8, 3.4 and 4.7 μm) were synthesized to determine the effect of cobalt loading (1%, 5% and 10% wt) in the H/ZSM-5 zeolite catalyst. The H/ZSM-5 zeolite catalyst and Co/ZSM-5 zeolite catalysts with 1 wt%, and 5 wt% of Co loading did not exhibit significant change in olefin selectivity. On the other hand, the various particle sizes of 10% wt Co/ZSM-5 zeolite catalyst affected the light olefin selectivity. The small particle size (1.8 μm) showed the greater light olefin selectivity than the larger Co/ZSM-5 particle sizes (3.4, 4.7 μm) because cobalt species dispersed in the channel of small particle size than large particle size. The cobalt species dispersed in the channel also affected the changes in the resident time and product selectivity.

title: The "Ho Chi Minh Factor" in Thai-Vietnamese relations

description: This thesis aims to study the role of Ho Chi Minh and his legacy in Thailand-Vietnam relations as well as the Thai ruling elite’s perception of Ho Chi Minh and its impacts on the bilateral relationship between the two countries through the period from the end of World War II to the present. The study adopted a qualitative research method. Research techniques included documentary research and interviews. Moreover, case studies were carried out in Nakhon Phanom and Udon Thani, where the Ho Chi Minh sites are located and where Vietnamese patriotic activities were active, to collect relevant data. The study finds that the “Ho Chi Minh Factor” has its stamp on every period of the developments of bilateral relations between Thailand and Vietnam since 1945. Accordingly, during 1945-1969, Ho Chi Minh himself played an important role in shaping Vietnam’s Thailand policy as well as in promoting Thai-Vietnamese friendship at the people-to-people level. Regarding Thailand, there has been significant change in the Thai ruling elite’s perception of Ho Chi Minh since the end of the World War II. During 1945-1948, the progressive Seri Thai’s government tended to see Ho as a patriot and extended invaluable assistance to Ho’s Viet Minh. With the outset of the Cold War, the Thai military regime saw Ho as a Communist leader whose policy posed a serious threat to regional peace, stability as well as to Thai national security, especially when the Vietnamese president was worshiped by the overwhelming majority of the Viet Kieu in Thailand. In the contemporary context, the Thai ruling elite has changed their perception of Ho, which is reflected through the establishment of the historical sites of Ho Chi Minh in Nakhon Phanom and Udon Thani. This is appreciated by the Vietnamese and is seen as a goodwill gesture for strengthening Thailand-Vietnam bilateral relations.
