title: Simultaneous analysis of antibiotic residues in food matrices using hydeophilic interaction coupled with tandem mass spectrometry

description: In this study, simple and sensitive method for simultaneous analysis of twenty four antibiotics belong to eight important classes : four sulfonamides, four quinolones, four macrolides, three tetracyclines, three aminoglycosides, three penicillins, two lincosamides, and amprolium in food was developed. The method involved a liquid extraction with the mixture of acetonitrile and 2% trichloroacetic acid in equal ratio, and removed fat with hexane before dilution of an extract with 10% formic acid : acetonitrile (9:1), and followed by hydrophilic interaction liquid chromatography (HILIC)-electrospray ionization tandem mass spectrometry in positive ion mode. The combination of effective extraction procedure and HILIC separation technique allowed quantification and confirmation of compounds with different polarity in a single chromatographic analysis. Several parameters affecting on the extraction efficiency, separation and sensitivity were optimized. The validation method has been performed in chicken matrix according to European Union Decision 2002/657/EC. Good performance data were obtained for recovery, precision, calibration curve, specificity and limit of detection. The average recoveries for all targeted analytes at MRLs concentration level were obtained in the range of 57 to 99 % with satisfactory %RSD of 2-14 (n=10) and also lower than acceptable value calculated from Horwitz equation. The limits of detection were 0.1-20 µg/kg for all compounds. Good linearity covered the concentration range of 0.25 MRL-2 MRL (sulfonamides ranged from 0.05 MRL-MRL, enrofloxacin and ciprofloxacin ranged from 0.1 MRL-MRL) with coefficient of determination higher than 0.99. The optimized method has been successfully applied to real chicken samples which can be detected enrofloxacin at 6.5 µg/kg. The method can also be employed for shrimp and egg samples analysis in routine laboratory for a different class of antibiotic residues from various matrices

title: Setting black-litterman reference point empirical evidence from Thailand

description: This paper establishes empirical evidence on in which method between setting market view based on single-factor model as in the Black-Litterman traditional paper or setting market view based on multi-factor model should be used. The results are as followings: In general, the results show that the multi-factor model using SMB and HML factor derived based on Black-Litterman model extension of Krishnan and Mains (2005) can capture more information of stock excess return than that of the traditional model which leads to less volatility in predicted return and less portfolio weight change from time to time. However, the multi-factor model of dividend-price ratio and earnings-price ratio can not be considered as an improvement of Black-Litterman traditional model because the predicted return derived from the model is much volatile. This leads to a significantly shift in portfolio weight which violates Black and Litterman’s initial intention to reduce portfolio weight shift in each period

title: Electrical efficiency of ethanol fuelled solid oxide fuel cell system : comparison between distillation and pervaporation for bioethanol purification

description: The overall electrical efficiencies of the solid oxide fuel cell (SOFC) systemintegrated with two different bio-ethanol purification processes, i.e. distillation and pervaporation were investigated and compared. It was found that the purification by pervaporation consumed less heat energy than that by distillation but the additional electrical power is required for the vacuum pump operation. In addition, two different levels of the permeate pressure for pervaporation were studied. The results show that the lowering pressure at the permeate side from 0.1 atm to 0.05 atm required less heat consumption but more electrical power consumption. For the SOFC system integrated with the purification process, the simulation studies were based on the condition that the net useful heat (Qnet) is equal to zero. It was found that the most suitable operating voltage is between 0.65 and 0.8 V and the operating temperature is in the range between 973 and 1173 K. For the effect of the ethanol recovery, the optimal ethanol recovery of the SOFC system integrated with distillation and pervaporation process are 95% and 99% respectively. The results indicate that the SOFC system integrated with pervaporation process with the permeate pressure of 0.1 atm offers the maximum overall electrical efficiency that is 41.6% (voltage = 0.7 V, temperature = 1073 K, separation factor = 923 and ethanol recovery = 99%)

title: CP in SSAs in Agritourism

description: The primary objective of this study is to explain customer decisions on participating in SSAs in agritourism with the TPB in which the mediating role of PR is considered. We also inspect the potential moderating effect of the ACE on the influence of PBC on PR. This study focuses on agritourism customers within the reach of online marketing communications, by collaborating with a professional Chinese online survey platform to collect data. We adopted a simple random sampling to send out questionnaires through e-mails and popular Chinese online chatting apps (QQ and WeChat), and offer each valid participant a compensation of 5 CNY. After being randomly assigned to one of two condition groups (with or without the ACE), interviewees were shown a scene, describing an agritourism consumption experience with dialogues (Appendix A), to read at their own pace. The consumption experience belongs to a fictional city dweller named “Yu” which sounds gender neutral in Chinese so that both male and female interviewees could easily identify with the character. They were asked to put themselves in Yu’s shoes and indicate how they thought Yu would respond in each setting. In both conditions, the scene involves three agritourism activities: tea-processing, self-catering, and angling. For each of three agritourism activities, interviewees were asked to select the perceived difficulty of the activity, the degree of interest in the activity, and the decision to participate (or not) in that activity for Yu. Then they answered questions about the PR, self-efficacy, and four demographic variables (age, gender, education and average monthly income) for themselves. Eventually, 625 (700) valid samples were acquired, of which 321 samples are under the condition with the ACE. The data shows a normal distribution in the age, education and income of samples, and the male-female ratio was 40:60.

title: Extraction of gold (III) using modified activated carbon

description: The activated carbons were modified with various potentially gold binding reagents by impregnation technique and their extraction efficiencies toward gold were evaluated. Tetrabutyl ammonium iodide (TBA) was found to be the most effective adsorbent for gold in terms of both extraction efficiency and speed. Various parameters were optimized around the preparation and utilization of this modified carbon in both batch and column methods. Several interfering ions commonly found in gold waste samples were found to have absolutely no effects to the extraction of gold. The adsorption isotherm was studied but no definite relation to any model was established. The breakthrough curve was used to demonstrate the improvement in gold extraction of the TBA-impregnated carbon over a commercial activated carbon and determine the adsorption capacity. The breakthrough capacity of the TBA-carbon and the commercial carbon were 90.62 and 18.00 mg/g respectively. The TBA-carbon was successfully applied to the recovery of gold from a real industrial waste sample.

title: Variation in aerosol concentration and composition over Changwat Nakhon Ratchasima, Thailand

description: The objective of this research is to investigate aerosol chemical concentrations and compositions in Thailand. Moreover, the relationship between aerosol chemical concentrations and temperature of the surface atmosphere were studied. The aerosol samples were analyzed for the ground-based aerosol compositions and concentrations during June 2007 to June 2008 at the Observatory for Atmospheric Research at Phimai, Changwat Nakhon Ratchasima. Multi-nozzle cascade impact samplers collected aerosol samples once per 15 days for 13 months. Each sample was the representative data of a half month. The samplers consisted of quartz fiber filters and polycarbonate filters. The samples were analyzed for carbonaceous aerosols by optical thermal OC/EC analyzer, for water-soluble aerosols by ion chromatography and for trace elements by particle induced x-ray emission. Meantime, the soil samples around the Observatory were determined using x-ray fluorescence. It was found that the combined measurable aerosol concentrations were high in November 2007 owing to sulfate but the concentrations were high in January 2008 due to OC. Both sulfate and OC were originated from human activities, for example, transportation etc. Consequently, the main sources of aerosols at the Observatory were the local activities. Cl⁻/Na⁺ ratios of the aerosols were different from the ratios of sea water and soil samples so salt particles at the Observatory originated from both soil dust and sea water. Moreover, the low surface temperature was the cause of the high aerosol concentrations because the aerosol could not be spread widely by wind.

title: Chemical constituents from the roots of Nauclea orientalis (L.) L.

description: The investigation for chemical constituents and their biological activities from the CH2Cl2, EtOAc and MeOH crude extracts of the roots of Nauclea orientalis (L.) L. led to the isolation of three new indole alkaloids, naucleaorien (3), naucleaoral A (5) and B (6) along with nine known compounds, naucleficine (1), naucleactonin A (2), vanillic acid (4), naucleidinal (7), 19-epi-naucleidinal (8), strictosamide (9), alpigenoside (10), sweroside (11) and pumiloside (12). The structures of all isolated compounds were elucidated by physical properties and spectroscopic methods as well as comparison with previous literature data. Most of isolated compounds were tested for cytotoxicity on HeLa and KB cell lines. Compounds 1, 3, 6 and 7 showed very modest cytotoxicity against both HeLa and KB cell lines (IC50 values of 6.8 and 6.8, 9.5 and 5.0, 7.8 and 9.5 and 5.5 and 4.8 µg/mL, respectively). Compound 5 exhibited significant cytotoxic activity against only HeLa cells (IC50 value of 4.0 µg/mL), while compound 8 showed only very modest cytotoxic activity against KB cells (IC50 value of 6.8 µg/mL). On the contrary, compounds 2, 9 and 11-12 were inactive (IC50 &gt;30.0 µg/mL). The results of testing for antimalarial activity of non-glycosidic indole alkaloids (compounds 1-2 and 5-8) showed that these compounds could be regarded as inactive (IC50 &gt;10.00 µg/mL)

title: A randomized controlled trail of knowledge sharing practice with empowerment strategies in pregnant women to improve exclusive breastfeeding during the first six months after delivery

description: This study aimed to investigate whether a knowledge sharing practices with empowerment strategies (KSPES) program on antenatal education and postnatal support strategies improves the rate of exclusive breastfeeding during the first six months after delivery compared with a standard knowledge of breastfeeding techniques. The study using a randomized controlled trial was conducted. Pregnant women of more than 32 weeks’ gestation were randomly assigned to receive a routine standard knowledge of breastfeeding techniques with KSPES on antenatal education and postnatal support strategies (study group) or to receive only a routine standard knowledge of breastfeeding techniques (control group) with 40 pregnant women in each group. Intra-group comparison of continuous variables was carried out using paired t-test and unpaired t-test for inter-group comparison. Compare the duration and rates of exclusive breastfeeding practices between the control group and the study group, by running the test on various groups, and calculated by Chi-square test. The relationship of factors that were associated with exclusive breast feeding was determined using the multivariate logistic regression analysis. The primary outcome was the rate of exclusive breastfeeding at 6 months after delivery. The secondary outcomes were the rates of exclusive breastfeeding at 7days, 14 days, 1, 2, 3, 4 and 5 months after delivery. The result showed that the rates of exclusive breastfeeding in the study group were significantly higher when compared with those in the control group at 14 days (82.5% vs 52.6%, P=0.005), 1 month (77.5% vs 52.6%, P=0.021), 2 months (62.5% vs 36.8%, P=0.023), 4 months (35.0% vs 7.9%, P=0.008), 5 months (25.0% vs 2.6%, P=0.012) and 6 months after delivery (20.0% vs 0%, P=0.005). And the mean scores of knowledge about breastfeeding, attitude toward breastfeeding and self-efficacy for self-management toward breastfeeding after intervention were higher than those before intervention in the study group (P&lt;0.001). Also those of them after intervention in the study group were higher than those in the control group (P&lt;0.001).The factors that effect on exclusive breast feeding were infants’ birth weight, attitude toward breastfeeding and mode of delivery. Increasing the infants’ birth weight and increasing the attitude toward breastfeeding were positively effect on exclusive breastfeeding while cesarean section was negatively effect on exclusive breast feeding. Conclusion: KSPES on antenatal education and postnatal support strategies significantly improves the rates of exclusive breastfeeding during the first six months after delivery with statistical significant at .05

title: A new prototype of automated teller machine transaction service of banks in Thailand

description: This thesis proposes a new design of ATM interface for banking service in Thailand. This proposed ATM interface is designed in a form of hierarchical menu structure based on seven frequent tasks on transaction service. From the experiment set-up, five occupations, students, employees, government and state enterprises officers, agriculturists, and merchants, of 105 participants were tested. Simulation of the designed interface was adopted for testing in laboratory environment. The ATM interface was established to compare with best existing ATM interface evaluated among five banks in term of effectiveness, efficiency, and satisfaction. In this study, the human-computer interaction principles were considered for designing a new interface. Usability criteria were used as the evaluation: effectiveness, efficiency, satisfaction, memorability, and learnability. The experimental results showed that the proposed ATM design reduced the error rate as well as increased effectiveness, efficiency, and satisfaction

title: Comparison of the in vivo total antioxidant capacity in healthy volunteers at the different curcuminoids doses by oxygen radical absorbance capacity assay

description: The total antioxidant activity in healthy volunteers obtaining the different dosages of curcuminoids extract was determined using the oxygen radical absorbance capacity assay (ORAC). Twenty four male and female Thai healthy volunteers were divided into three groups. Group A and B were administrated with curcuminoids extract at the dose of 500 mg/day and 6g/day, respectively. Group C received vitamin E supplement at the dose of 200 IU/day. Every subject was treated for seven days. Blood samples were collected before experimentation and on the first and seventh days up to 12 hrs. after administration, were immediately centrifuged to separate plasma and kept at the -48°C for subsequent analysis. No any adverse reaction was observed in any subject during and after 7 days of curcuminoids extract and vitamin E supplementations. Before experimentation, the concentrations of α-tocopherol of all subjects were within the normal range of healthy people (7.58 – 19.52 µg/ml). The ORAC values comparing before and after curcuminoids extracts administration of subjects in group A were ranged from 5,797-15,689 and 8,269-20,186 µmol TE/L, respectively, and those of subjects in group B were ranged 9,022-24,834 and 3,530-20,595 µmol TE/L, respectively. No significant increase in the ORAC values were observed either in group A subjects or group B subjects (p=0.270 and 0.33, respectively). For the subjects in group C, the ORAC values before and after vitamin E supplementations were ranged from 8,422-13,922 and 9,216-23,574 µmol TE/L, respectively. From the analysis of plasma endogenous α-tocopherol, there was statistically significant increased in α- tocopherol concentration from 9.16 ± 1.21 to 14.38 ± 2.85 µg/ml (p =0.007). The increasing of α-tocopherol concentration was related to antioxidant activity of α-tocopherol. However, there were no statistically significant increased in the ORAC values (p =0.585). Therefore, it is suggested that the supplementation of any antioxidants may not be essential for any healthy people. In addition, there are possibly balance functions to regulate the maximum antioxidant activity in our body.

title: Stability of mixed-type trigonometric and quadrstic functional equations

description: The first part of the thesis proves the stability of a generalized trigonometric functional equation F G H K over the domain of an abelian group and the range of the complex field. Several related results extending a number of previously known ones, such as the ones dealing with the sine functional equation, the d’Alembert functional equation and Wilson functional equation, are derived as direct consequences and applications to operators in Banach algebra are derived. The second part of the thesis first determines differentiable solution functions of a mixed-type trigonometric and quadratic functional equation of the form F G H K L M over the domain of the real number field and the range of the complex field. Then the stability of this latter functional equation over the domain of an abelian group and the range of the compiex field, is proved.

title: Development of AFLP molecular markers for cultivar identification of cured tobacco leaves

description: Tobacco cultivars grown in Thailand are separated to 2 major groups: local and imported cultivars. However, current approaches to distinguish tobacco cultivars are not accurate enough, particularly for dry-cured tobacco. In this study AFLP molecular marker was introduced to investigate genetic differences between cured leaf-materials of 23 tobacco cultivars. The AFLP result showed that three primer-pairs (E[subscript AAG] / M[subscript CAA], E[subscript AAG] / M[subscript CGC] and E[subscript ACT] / M[subscript CAG]) gave a total of 139 AFLP fragments, of which 103 (74.1%) were polymorphic bands. Among these primers, E[subscript ACT] / M[subscript CAG] primer gave both highest number of AFLP-PCR fragments (59 bands) and polymorphic bands (83.1%). Furthermore, this primer-combination produced one cultivar-specific band of Virginia cultivars. This cultivar-specific marker would be useful in identification and confirmation of Virginia genotype in tobacco trade. Genetic relationship trees based on NJ and UPGMA techniques revealed clusterings similar to each other. Almost all local cultivars were closely related with each other and also with Burley and Turkish imported cultivars. The supgrouping of local cultivars tended to form following their cultivating regions. Among the imported cultivars, their clusterings were not only based on cultivating area but also on the imported cultivar groups (Virginia, Burley and Turkish). Virginia cultivars were clustered separately from other local and imported cultivars. In conclusion, this AFLP marker technique could separate Virginia cultivars from other cultivars grown in Thailand. And these results could be a fundamental information for other tobacco genetic researches in the future
