title: Practice of contraception in premarital and marital sexual relationship among Myanmar youth migrants in Bang Bon districts, Bangkok and their reproductive health services accessibility

description: Migration becomes a global issue nowadays not only in economic but also in health aspects. Thailand is one of the major migrant receiving countries in South East Asia. More than 80% of migrant workers in Thailand are Myanmar and concentrated in the age group of 15-24 years. No matter where they settle, it is always true that the migrant youths suffer the health problems and inaccessibility more than the native youths. The objective of this study is to assess the sexual practice and contraceptive usage among Myanmar migrant youths in Bang Bon District in Bangkok and their reproductive health services accessibility. The study was cross-sectional descriptive study carried out by face to face interviewing to 413 migrant youths (15-24 years). The results were analyzed by chi square test, Fisher’s Exact test and Logistic Regression to see the independent variables as associated factors to the current contraception practice. The results revealed that 24.7% of migrant youths had premarital sexual relationship and 60.0% of both married and unmarried youths used contraception in their premarital and marital sexual relationship. However, their knowledge towards STIs and contraception was quite low but their attitude and belief were satisfactorily fair and good. After multivariate analysis, marital status (&lt;0.001), duration of stay in Bangkok (0.001), persons staying together (&lt;0.001), discussion about contraception with their partners (0.001), their level of knowledge (0.027) and attitude (0.005) and health information availability (0.005) were found statistically associated with their current usage of contraception. Overall findings indicated that though the migrant youths practice contraception widely, their level of knowledge was still low indicating their needs of health information. This study indicates that effective communication, information dissemination, sexual health counseling become crucial needs to the migrant youths who are vulnerable to sexual and reproductive health risks. Exploring the differences of the findings of this study and the previous studies, qualitative study would be helpful for the health policy makers of migrants to have better understanding of the youths’ nature regarding sexual and reproductive health

title: Living and working environment, and factors associated with the safe sex behavior and sexually transmitted infection of Myanmar migrant workers in Muang district, Ranong province, Thailand

description: A cross-sectional descriptive study was conducted on March 2010 with the objective of assessing the living and working environment and factor associated with the safe sexual behavior and health status related to unsafe sexual behavior of Myanmar migrant workers in Muang District, Ranong Province, Thailand. Multi-stage purposive sampling method was used for the study and 406 households were recruited in the survey. For data analysis, chi-square test was used. Respondents aged between 19 and 50 years from each household were selected and interviewed by using self-administered questionnaires. Female and male respondents are selected half by half (female 203 and male 203). Out of 406 respondents, 41.4% is single, 50.7% are married and 5.7% and 2.2% are divorced and widowed. Their major jobs are Factory worker and fisherman. Among the 406 respondents, half (51.0%) live in dawn town and over 50% (205) respondents live with roommates. For working environment, over half (224) respondents work 10-14 hours per day. There is significant relationship between gender (P-value 0.001), type of job (p-value 0.001), job needs to travel (0.001) duration of stay in Thailand (0.001) and safe sex behavior. In 203 male respondents, 109(52.7%) had sex with sex workers and only 36.2% use condom when have sex with sex worker. There is significant relationship between gender (p-value 0.006), marital status (p-value 0.041), duration of stay in Thailand (p-value 0.001), working years(p-value 0.001), job location(pvalue-0.000), job needs to travel(p-value 0.001) and sexually transmitted infection. Health education and condom promotion programs are necessary for the migrant workers especially in fishermen group because this group has poor sex behavior and high prevalence of STI. Also health education program for sexually transmitted infections and provide more STI clinics are needed. 16.9% of total respondents had STI. In further study, other indicators to elicit more about the safe sex behavior of the females should be used as females think some issues are especially concern with male only. For more information about safe sex behavior, further study should not only focus on descriptive study but also point out for action research for prevention and control of it

title: Polymer coating of fine particles using supercritical carbon dioxide technology with ethanol cosolvent

description: For the improvement of therapeutic effectiveness, coating of drug particles with polymer has been used widely in pharmacy and medicine for controlled-release applications. The polymer coating could help improve the circulation of drug and maintain the concentration of therapeutic agents in the blood vessels. In this research, coating of microsize and nanosize powders with a polymer has been investigated for the production of controlled-release particulate drug delivery systems, such as microcapsules and nanospheres. Poly(D,L-lactide-co-glycolide) or PLGA, as polymer and 1.4-micron silica (SiO₂) and 70-nm titanium dioxide (TiO₂) powders as core particles were employed as the coating model for the investigation. As a benign alternative to toxic organic liquid solvents, a supercritical fluid (SCF) mixture of carbon dioxide (CO₂) mixed with ethanol cosolvent, was used to dissolve PLGA in the preparation of coating solution. With the use of SCF solvent, disposals of environmentally hazardous wastes from the process and denaturation of therapeutic agents in the product could be avoided. Rapid expansion of supercritical solution (RESS) process was utilized to produce polymer particles, which can be used for coating, as well as to generate polymer-coated microsize or nanosize particles. PLGA was dissolved in supercritical carbon dioxide (SC-CO₂) to form a supercritical solution at 25 MPa and 313 K. Ethanol, up to 23.8 wt.%, was added to SC-CO₂ to enhance the PLGA solubility. The charged amount of PLGA in SC-CO₂ with 23.8 wt.% ethanol was approximately 0.15 wt.% of the supercritical solution. The RESS process was performed by spraying supercritical solution through a capillary nozzle to ambient air, leading to precipitation of well-dispersed PLGA particles. The average particle size of the precipitated PLGA particles ranges from 55 to 330 nm, depending on the ethanol concentration. For particle coating, SiO₂ and TiO₂ core powders were suspended in the supercritical solution before performing the expansion. The precipitation of PLGA particles accompanying with deposition of the precipitated particles on the core particle surface, solvent evaporation and disintegration of agglomeration of the core particles resulted in formation of coated particles in the form of both individual particles and agglomerates. The thickness of the coating layer was non-uniform but could be estimated to be around 10 to 100 nm

title: Innovative process for free-vulcnized rubber latex production

description: Field natural rubber latex was concentrated by creaming method via addition of creaming agents, namely carboxymethyl cellulose (CMC), hydroxyethyl cellulose (HEC) and hydroxypropyl methyl cellulose (HPMC). The effects of creaming agent concentration, creaming time and temperature on dry rubber content (DRC) were studied to determine the optimum condition for latex creaming process. Creamed latex was cured by vulcanization in a stirred reactor with sulfur elements and tetramethylthiuram disulfide as curing agent. Free-vulcanized latex obtained from the reaction with varying temperature, cure time and curing agent concentration were made into films and dried at room temperature. Tensile properties, elongation at break, hardness of the film products were measured. Crosslink density, chloroform number and swelling index of latex were also investigated. It was found that optimum condition for latex concentrate was using HPMC as creaming agent at 0.6% concentration, at room temperature, for 24 hours. For vulcanization of creamed latex, the maximum tensile strength was obtained from TMTD 2 phr at vulcanization temperature of 50 °C and cured time of 3 hours. At lower vulcanization temperatures, longer cured time was required. Chloroform number and swelling index showed that the latex compounds were not completely vulcanized

title: Corporate governance and the cost of capital of the companies listed in the Stock Exchange of Thailand

description: This thesis investigates the relationship between corporate governance and cost of capital of the companies listed in the Stock Exchange of Thailand (SET) during 2000-2007. This study uses corporate governance index (CGI) which capture major aspects of corporate governance that are board structure, conflict of interest, board responsibility, shareholder rights, and disclosure and transparency. The cost of debt is estimated by predicting the credit rating which estimated by Altman model, Blume model, Campbell model, Shumway model and Zmijewski model and being converted in to the cost of debt by using the yield spread technique. The cost of equity calculated from CAPM, three-factor model, DDM and Easton model. After ignoring invalid model namely CAPM and DDM, the regression result shows a negative relationship between corporate governance, the cost of debt, the cost of equity and the cost of capital. The result can be interpreted that corporate governance can reduce the cost of capital

title: Demand for medical care : an economic analysis of Kala Azar in Nepal

description: This study contributes to the literatures by measuring in quantitative terms the potential effects of poverty-alleviation programs on the incidence of disease; exploring road map of decision making process for health seeking; examining utilization patterns of health services based on first consultation and factor influencing multiple consultations to the providers. For empirical analysis, the sophisticated statistical tools are applied to recently collected data from secondary and primary sources in Nepal. The study focuses on Kala Azar (KA) - a neglected tropical disease, also known as disease of poor. The results of demand analysis suggest that absolute poor are highly price sensitive, although health services are provided free of cost at the public hospitals. Provision of free health care may not be sufficient to encourage utilization of health services by the poor patients or households. Based on empirical model, this study has also explored the implication of introducing demand side financing and better access to information on the utilization of public hospitals. The utilization of public hospital can be increased from 16 percent up to 63 percent due to price effects; however, the effect of income on utilization rate is relatively small. Better access to information reduces likely of using self-care or home care; drug stores and private clinics and increases the utilization of public hospitals. A holistic approach rather than traditional disease-centered approach can break the links between poverty and KA; and expansion of KA care in public and private providers and better access to information can help to control of KA in Nepal

title: Dynamic properties of Chiang Mai sand using cyclic direct simple shear test

description: Chiang Mai province is located in northern part of Thailand, wherein low to medium earthquake can occur. Therefore, this research aims to present an assessment of dynamic properties of Chiang Mai sand using cyclic direct simple shear test. Two of the most important parameters of dynamic properties in any dynamic analysis related to soils are shear modulus and damping ratio. The monotonic direct simple shear apparatus, which is developed at Norwegian Geotechnical Institute by Bjerrum and Landva, is modified to cyclic direct simple shear so as to be able to determine dynamic properties of Chiang Mai sand. Drained (constant normal stress) tests are carried out with saturated sand sample reconstituted by water pluviation method, which can closely replicate the in-situ fabric of natural sand deposits. In this study, relative density, vertical stresses, shear strain amplitude, and frequency are varied to observe their effect on sand dynamic properties. It can be concluded from the testing results that shear modulus and damping values mainly depend on vertical stress and shear strain. Shear modulus decreases with increasing shear strain amplitude. Oppositely, it increases with increasing vertical stress. The value of hysteretic damping increases with increasing shear strain amplitude. In contrast, when damping ratio decreases with increasing values of vertical stress. The experimental results of present study compared with previous investigations are found to be in fair agreement. All in all, this research is the first work focused on dynamic properties of Chiang Mai sand, which gives great distribution to the calculation of ground response during an earthquake. It also facilitates the following researchers who want to conduct further research on advanced soil laboratory testing about cyclic soil response in Chiang Mai as well as in Thailand

title: The role of designated national authority in driving clean development mechanism (CDM) in Thailand

description: Clean Development Mechanism (CDM) has been initiated in Thailand since 2005, but limited numbers of CDM projects have been implemented in Thailand as compared to other Southeast Asian countries. Thailand would receive significant benefits from the CDM if it was implemented widely. However, the causes hindering the project development have not been fully understood, especially the role of Designated National Authority (DNA) on CDM execution. The objectives of this research are to investigate major factors impacting CDM performance and to analyze the roles of the DNA in driving CDM projects in Thailand. The research was carried out by conducting a survey and interviewing related stakeholders to identify key factors which could have impacts on CDM project implementation and performance such as organization capacity, stringency of approval procedure, and speed and accuracy of process. The study shows that financial factor significantly hinders CDM project development in Thailand. The implementation cost, uncertainty of CERs price, and investment fund support are the major considerations to the project developers in making decision to implement CDM project. In addition, related stakeholders still lack the understanding of CDM implementation procedure. The DNA therefore needs to promote and support the CDM implementation nationwide in more effective and continuous manner, specifically a suitable financial supporting program has to be urgently developed. In essence, a national policy agenda for greenhouse gas reduction will enhance the success rate of CDM project implementation in Thailand

title: Modification of titanium dioxide support for carbon monoxide oxidation

description: This research is to study the effect of surface modification of TiO₂ support on the catalytic activity in CO oxidation. Two methods were employed for surface modification of TiO₂ support: the creation of defective sites on TiO₂ surface and the modification with trace element. The results found that the presence of higher amount of Ti³⁺ on the larger crystallite size TiO₂ stabilizes small metal particles during impregnation, calcination, and reduction steps via stronger metal-support interaction; hence higher CO oxidation activities. In addition, the modification of TiO2 support with trace element can improve the CO oxidation activity. All of element dopants (i.e., Al, Si and P), the Si-modified TiO₂ showed the highest catalytic performance of Ag/TiO₂ catalyst. However, there existed an optimum content of Si/Ti molar ratio at ca. 0.05-0.1 which resulted in an improved catalytic activity of Ag/TiO₂ in CO oxidation. There was no improvement in CO oxidation activity of the Ag/TiO₂ catalyst when the Si/Ti was further increased to 0.3 due probably to the formation of amorphous SiO2 instead of the Ti-O-Si bond. The P-modified TiO₂ supported Ag catalysts using phosphorus precursor in the form of oxide promoted the weak adsorbed oxygen species and resulted in catalytic activity improvement in CO oxidation

title: Effects of heat on secondary structures of silk fiber studied by ATR FT-IR microspectroscopy

description: Attenuated total reflection Fourier transform infrared (ATR FT-IR) microspectroscopy has been employed to characterize the silk fiber. The character of silk spectrum contents of the four major peaks: amide A, amide I, amide II and amide III. The difference of spectra between the un-degummed and degummed silk fiber is the shoulder of amide I band at 1697 cm⁻¹. It was assigned to the anti-parallel β-sheet. The β-sheet is one type of secondary structure that shows the crystallinity. The crystallinity is related to the properties of silk fibers such as the softness and dyeability. Consequently, the properties of silk fiber are associated with the secondary structure. The secondary structure contained in the silk fiber could elucidate by curve fitting analysis. The amide I band of spectrum was used to determine the quantity of individual secondary structure. In this study, the controlled conditions are temperatures, times and quenching methods. According to the varied conditions, the quantity of secondary structure that was calculated from individual peak area has fluctuated. It is imply that it does not have significantly changes
