title: Feasibility study of using Pygmy waterboatman, Micronecta grisea, instead of Temephos larvicides in controlling of Aedes aegypti larvae

description: Pygmy waterboatmen, Micronecta grisea, were collected and used to establish laboratory cultures in order to study the predation rates and feeding behavior of nymphal instars (N) and adults against third instar larvae (L3) of Aedes aegypti to assess their potential for biological control. The body length, head length and head capsule size of 330 nymphs and 71 adults of M. grisea, collected from Bang Bua Thong District, Nonthaburi Province, Thailand, were measured using a stereo microscope. Five discrete nymphal instars (N1-N5) plus adults could be classified by body length; the 1st (N1; 0.54-0.65 mm), 2nd(N2; 0.69-0.84 mm), 3rd(N3; 0.9-1.11 mm), 4th(N4; 1.29-1.56 mm) and 5th(N5; 1.74-1.98 mm) nymphal instars plus adults (2.07-2.43 mm). Nymphs classified as three discrete size categories, small (N1&N2), medium (N3&N4) and large (N5), including adults were examined for predation rates and prey handling times when fed L3 Ae. aegypti at different predator to prey ratios, Prey searching and handling times decreased with increasing size of M. grisea and were consisten with the Type II functional predator-prey response. The 5th nymphal instar and adult of M. grisea were tested the ability of M. grisea to feed on L3 Ae. aegypti to examine their efficiency. Temephos zeolite granules, applied in water at 1 ppm, were also tested against Ae. aegypti larvae. The number of live mosquito larvae left was recorded and found that, within 24 hours, temephos and adult showed the highest mortality percentages (100% and 99%, respectively), whereas the fifth instar nymph killed 64% of the mosquito larvae. Feeding behavior of M. grisea was observed during the feeding tests. Compared with adult of M. grisea, the fifth instar nymph took more time feeding on Ae. aegypti larvae. When using one adult M. grisea, within 72 h, the highest larval mortality percentages occurred at the lowest prey densities which also showed in further feeding tests in small scale containers, exhibited higher prey mortality (percentages) at the lower prey density. The effects of temephos on M. grisea were also tested and results revealed complete mortality of M. grisea within 8 hours of exposure. As larvicides applied in the field are toxic to M. grisea, but M. grisea's satisfactory results provided excellent control against Ae. aegypti larvae, controlling methods should be safe in the areas as well as promoting benefits for conservation of effective predators to control mosquito population in the nature.

title: Synthesis of poly[n-isopropylacrylamide-co-[2-(methylthio)ethyl methacrylate]] for gold(III) ion adsorption

description: A new copolymer poly[N-isopropylacrylamide-co-[2-(methylthio)ethyl methacrylate]], poly(NIPA-co-MTEMA), with bis(acrylamide) as a crosslinking agent was synthesized by free radical polymerization. The optimum condition for the synthesis of homogeneous and heterogeneous poly(NIPA-co-MTEMA) could be achieved with 10 mM MTEMA in 5.0 %(v/v) ethanol and 30 mM MTEMA in 20.0 %(v/v) ethanol, respectively. The copolymers were characterized by Fourier transforms infrared and Raman spectroscopy, scanning electron microscope, thermal gravimetric analysis and differential scanning calorimetry. The lower critical solution temperature (LCST) of homogeneous poly(NIPA) and poly(NIPA-co-MTEMA) polymers was nearly about 32 ℃. The adsorption of gold(III) ion was studied in batch method. The optimum pHs for the adsorption of homogeneous and heterogeneous polymers were 1-3 and 1-5, respectively. The suitable adsorption time was 3 hours at 50 ℃ when using a rod shape copolymer (0.7 cm diameter and 1 cm length). The adsorption behavior of homogeneous polymers fitted to the Langmuir and Freundlich isotherms. For heterogeneous polymers fitted to the Freundlich isotherm. The desorption equilibria were reached within 2-3 hours at 10 ℃ by 0.1 M Thiourea in 5% HCl except for heterogeneous poly(NIPA) for which DI water was appropriate.

title: Alpha-Glucosidase inhibitors from bael Aegle marmelos and jew's mallow Corchorus olitorius leaves

description: Discovery of α-glucosidase inhibitors has been actively pursued with the aim of developing therapeutics for the treatment of type 2 diabetes. We have examined the inhibitory effect of Thai medicinal plants against α-glucosidase. The leaves of Aegle marmelos and Corchorus olitorius were selected for this investigation. Bioassay-guided fractionation led to the isolation of active principles. The isolation of dichloromethane and methanol crude extracts from leaves of Aegle marmelos afford three novel phenylethyl cinnamides named anhydromarmeline (1), aegelinosides A (7) and B (8) along with eight known compounds, anhydroaegeline (2), (-)-tembamide (3) dehydroaegeline (4), (-)-aegeline (5), (-)-O-methylether aegeline (6), alangionosides L (9), N-2-ethoxy-2-(4-methoxyphenyl)ethyl-cinnamide (10) and N-(2-(4-hydroxyphenyl) ethyl)-cinnamide (11) as well as four known flavonoid glycosides (12-15). All the isolated compounds from this plant were tested for inhibitory activity against α-glucosidase. The most active principles against α-glucosidase were 14 (IC50 0.34 mM) and 15 (IC50 0.46 mM). In addition, two new flavonoid glycosides named corchorusides A (16) and B (17) together with a known triterpenoid glycoside named capsugenin-25,30-O-β-diglucopyranoside (18) were isolated from methanolic extract of Corchours olitorius leaves. Corchorusides A (16) showed the most inhibitory effect with IC₅₀ value of 0.18 mM.

title: Molecular epidemiology of human bocavirus and new discovery human bocavirus 2

description: The recently discovery virus base on metagenomic technique, human bocavirus (HBoV), had been screening in this study. Nasopharyngeal (NP) aspirate and stool from acute diarrhea patients and healthy children were corrected. The result showed that HBoV can be detected in NP aspirate 6.62% and diarrhea stool samples 0.9%. Where as could not be detected in healthy children stool samples. The co-infection with other respiratory viruses also found (40%) and there were no clinical specific manifestations for HBoV; however, fever and productive cough were commonly found. The results from complete coding sequences showed that the most conserved regions of HBoV are the NS1 and NP1 genes, whereas VP1 and VP2 showed frequent variations. The epidemiological study of newly discovered species of Bocavirus genus, HBoV2, which show about 74% amino acid identity when comparing with HBoV had been also focusing in this study. HBoV2 could be only found in diarrhea stool samples that collected in both Thai (0.61%) and UK patients (0.64%). Moreover, it has shown higher variation at the genome level than HBoV. In conclusion the molecular epidemiological study of HBoV and HBoV2 provided more information of these viruses.

title: Nature of accessibility to health care services and health-related quality of life among adult Myanmar migrant workers in Mahachai Sub-District, Samut Sakhon Province, Thailand

description: The objective of this research was to assess the health-related quality of life among adult Myanmar migrant workers (age 18-59 years) in Mahachai Sub-district, Samut Sakhon Province, Thailand. It was a cross-sectional study. This research utilized the multi-staged sampling with 400 respondents for quantitative research, and two health care service providers for qualitative research. The data was collected in early February 2009. For quantitative study, the instrument used in this study was a constructed and pre-tested face-to-face interview adapted from WHOQOL-BREF, and for qualitative study, in-depth interview guidelines passing ethical review COA no. 108/2009 issued on 28 January 2009. Data was analyzed by applying descriptive statistics (frequency, percentage, mean, standard deviation, range and median) to describe the data, and inferential statistics (unpaired t-test and one-way ANOVA) to examine the relationships between independent and dependent variables. For qualitative data, ordering, coding summarizing and drawing conclusion were done. The results revealed that only 2.75% of the respondents had high level of health-related quality of life. The rest of the respondents reported that their health-related quality of life was moderate and low, 94.0% moderate level, followed by 3.25% low level of quality of life. For socio-demographic characteristics respondents who were married, having more than two family members living in Thailand, had stayed in Thailand more than or equal to eight years, could speak Thai language fluently, no education status, high income, manufacture or agriculture workers, no history of sickness within last four weeks, and having access to health care services and getting treatment when sick, were discovered to have higher mean score of quality of life than others. For living and working conditions, respondents who lived in a rent place, had work permit, length of current job 4 years or above and who were satisfied with working conditions had significantly higher health-related quality of life. For accessibility to health care services, perception of being difficult to go to the health facility, crowdedness of the health facility and having health insurance card were found to have associated with health-related quality of life. Overall findings indicated that the migrant workers were on the horned dilemma while searching for better quality of life. Future studies should consider many subgroups within Myanmar migrant workers as well as Thai workers to be able to compare the quality of life to provide stronger evidences. Finally, policies to improve access to health care services and higher quality of life in order to create a win-win situation for both migrant workers and host Thai nationals are recommended.

title: The localization of Seven Eleven in Bangkok

description: The 7-Eleven convenience store franchise is now the largest chain store of any category in the world surpassing even McDonald’s when compared by store numbers. As 7-Eleven is a multinational marketer and distributor of various modern style foods and services, which are all packaged together as a service promoted as ‘convenience’, the franchise is in a unique position to influence consumers and tastes in various parts of the world. In Thailand, but in Bangkok especially, the 7-Eleven franchise brand has been borrowed by one of Thailand’s most successful multinational companies, CP Group, and one of the world’s largest agribusiness firms. Bangkok possesses one of the heaviest concentrations of 7-Eleven stores of any city in the world. As such, the 7-Eleven franchise has been at the center of CP Group’s latest plans for driving growth and international competitiveness since they experienced debt problems after the 1997 Asian Financial Crisis. This thesis takes the view that this has allowed CP Group, primarily through the strategies it has employed as Thailand’s sole franchisor of the 7-Eleven brand, to have significant influence on local food tastes and perceptions of convenience. Equally important, if not more so, is the role of local consumers in localizing 7-Eleven in Bangkok. The process of adaption and adoption of foreign influences is often referred to academically as localization. This study uses the theory of localization to make the argument for the unique ability of local actors to shape and give character to processes that take place both within and outside national borders. Although this thesis is still written from the viewpoint of an outsider, the interdisciplinary methodology employed seeks to understand the processes of localization more in terms of what is happening in Thailand rather than outside of it. This counters and deepens arguments about the supposed homogenizing influences of globalization. Furthermore, an outside perspective applied to examining the localization of 7-Eleven in Bangkok allows for processes in Thailand to be compared with and partially reconciled with similar but not identical processes that are taking place in other parts of the world. As such, it is argued in this thesis that the localization the 7-Eleven franchise in Bangkok offers an exploration of how modern convenience is institutionalized and shaped by local actors. As far as comparisons with external actors go, it is argued that processes of development, growth, multinational business practices and demographic change share similarities between and across countries.

title: Enhancing hydrocarbon recovery from gas condensate reservoir via carbon dioxide injection

description: Increasing condensate recovery in a gas condensate reservoir is a challenging task. When the reservoir pressure falls below the dew point, retrograde condensate condenses and accumulates in the pore system, causing a blockage problem. Furthermore, some of the valuable condensate will be left in the reservoir as residual oil. One of the most effective methods of solving this problem is to injecting gas into the formation. Gas injection allows enhanced condensate recovery by reservoir re-pressurization and liquid re-vaporization. The injected gas can be natural gas or other inert gases, depending on availability. The use of CO2 as injected gas also achieves the purpose of CO2 sequestration into geological storage. In this study, a compositional simulator was used to simulate CO2 injection in a hypothetical gas condensate reservoir. The simulation results show that CO2 injection does effectively maintain reservoir pressure above the dew point pressure, preventing condensate dropout within the reservoir. When injecting CO2 after condensate accumulates, CO2 can still re-vaporize liquid drop-out around the wellbore. The simulation results also demonstrate that gas production and CO2 injection rate do not have significant effect on oil and gas recovery. However, the starting time for CO2 injection has important effects on hydrocarbon recovery. To obtain the maximum oil recovery, the injection should start shortly after the bottomhole pressure drops below the dew point pressure.

title: Determination of school nurses' opinions toward their works and parents' perceptions of school nurse's roles and health services in Bacninh, Vietnam

description: This research aimed to examine opinions of school nurses towards their works with children and the perceptions of primary school parents/ guardians of school nurse’s roles and health services which were provided by school nurses including the both categories of schools, which had school nurse and did not have school nurse. This was a descriptive study using both qualitative and quantitative methods, with in-depth interview following guideline question for 2 school nurse and school health staff, and with self - responding questionnaires for 580 parents/guardians of primary school students in 2 primary schools in BacNinh City. In the school having school nurse, the number of class room and students was larger than in school without school nurse. About the respondents, there were 53.1% males, with the mean of age was about 37.5 years, about one-third of parents/ caregivers of both schools working for the government and 17.1% were private company employees. The study found that both subject groups including school nurse and school health staff and almost parents thought that it needed a permanent school nurse to work full-time. The findings pointed out 6 prior roles of school nurse, including (1) providing first aid and emergency care for student at school, (2) performing health screenings, (3) managing student health records, (4) providing a sanitary school environment, (5) consulting health issues for students, teachers and parents, (6) providing health education. There were shown 5 necessary activities that school nurse can provide, which included (1) Providing lunch with food safety hygiene to students and teachers, (2) Checking up student’s health and Maintaining student’s health record, (3) Providing necessary medicine for students and teachers, (4) Providing fresh water and sanitary environment, (5) Providing teaching-learning and playing environment for students and teachers. All of these roles and services accorded with the school health tenors of Ministry of Health and Ministry of Education Training. The study also found that, the parents/guardians in school having school nurse know correctly about setting school nurse and health clinic exiting in their children school than in school having school health staff (p&lt;0.001) and they got more information about school health programs from school than in school having school health staff (p&lt;0.001). Besides, the results showed that the parents agreed to support for school health services (94.6%) and 81% of them wanted to pay directly for school. To assess effectiveness on implementing the roles of school nurse and school health services there need to have the other investigation study and the other should study about mobilization of social resources and community participation.

title: Spectral Theory on Unital Commutative full Symmetric Krein C*-Algebras

description: An involutive algebra (A,*) is called a Krein C*-algebra if it admits at least on eBanach algebra norm and one fundamental symmetry of (A, *), i.e., α ϵ Aut(A,*) such that α² = 1[subscript A] and ||α(x)*x|| = | ||² for all x ϵ A. The ultimate goal is to develop a spectral theory on unital commutative Krein C*-algebras when the odd part is a symmetric imprimitivity bimodule over the even part and there exists a suitable "exchange symmetry" ε between A₊ and A₋. The result we obtained is a generalization of spectral theory on unital commutative C*-algebras

title: Establishing integrity : parenting process among parents of healthy adolescents

description: Parenting during adolescence is crucial for children development and health. However, there is less evidence that could explain how parents raise their adolescents, especially, in Thailand. The current study was aimed at explaining the parenting process among parents of healthy adolescents in the Thai context. A grounded theory study design was chosen. Nineteen parents (families) of healthy late adolescents aged 18-20 years were in-depth interviewed. Transcripts were analyzed by using the constant comparative analysis process. Data collecting and analyzing, including memo writing were done simultaneously until finishing the research process. Finding indicated that the process of "Establishing integrity" (Karn Saang Serm Kwam Mun Kong) occurred when the parents recognized the child being an adolescent, and then the three major parenting activities were performed simultaneously throughout the adolescent period, which consisted of: "reinforcing connectedness," "enhancing maturity," and "protecting." Eventually, the parents believed that their adolescent was being an adult that had demonstrated his/her integrity regarding maturity and well-being. In conclusion, adolescence is a challenge and usually necessitates adjustment in the parenting process and activities suited for the child developmental stage to promote the adolescents’ integrity both body and mind. The benefits of this study will assist nurses and other health care providers. They can apply this substantive knowledge to promote effective parenting of adolescents for parents with the appropriate intervention. Future research should be focused on testing this process model with a large population. It should include developing a measurement device for assessing the process of parenting adolescents suited for the Thai context.

title: Synthesis and polymerization of 3,4-dialkoxy thiophene

description: Poly(3,4-ethylenedioxythiophene) is acknowledged for its high electrical conductivity but insoluble in common organic solvents, leading to difficulties in fabrication process. In attempts to solve this problem, new monomers were synthesized by modifying the substituents on the thiophene rings. They were used to prepare polythiophene via chemical, thermal solid or liquid state polymerization techniques. Brominations of 3,4-ethylenedioxythiophene, 3,4-dimethoxythiophene, and 2'-hydroxymethyl-3,4-ethylenedioxythiophene provided 2,5-dibromo-3,4-ethylenedioxythiophene, 2,5-dibromo-3,4-dimethoxythiophene, and 2'-hydroxymethyl-2,5-dibromo-3,4-ethylenedioxythiophene in 85, 80 and 72% yields, respectively. Subsequent substitutions with 2-bromoethanol on 2,5-dibromo-3,4-ethylenedioxythiophene yielded the crown-ether fused thiophene derivative 2 in 22% yield. When, using 3,4-dimethoxythiophene as the precursor in other substitutions, 2'-hydroxymethyl-3,4-ethylenedioxythiophene 3 and 3,4-dibenzoyloxythiophene 6 could be obtained both in 20% yields. Finally, chemical polymerization of 3,4-dihydroxythiophene 5 and thermal polymerization of 2'-hydroxymethyl-2,5-dibromo-3,4-ethylenedioxythiophene provided their corresponding polymers in 98% and 54% yield, respectively
