title: Thai nationals with dual nationality status

description: Despite the historical disapproval of multiple citizenships, policies and opinions of many countries on citizenship are shifting as the world environment and attitudes have changed considerably. The rise of globalization has encouraged a greater movement of people locally and internationally. As a consequence, the notion of dual nationality - the act of having citizenship in two countries at the same time- is emerging throughout the world. Dual nationality is a result from the fact that there is no uniform rule of international law relating to the acquisition of nationality. Each country has its own laws on the subject, and its nationality is conferred upon individuals on the basis of its own independent domestic policy. Individuals may have dual nationality not by choice but by automatic operation of these different and sometimes conflicting laws. There are also a number of Thai nationals with dual status residing in both Thailand and overseas due to an increase in number of intermarriage and out-migration of Thai people. The study finds that, according to Thailand's nationality law, there are many ways for a Thai national to obtain dual nationality, both at birth – based on the jus soli principle and the jus sanguinis principle; and after birth – through marriage with an alien spouse and through naturalization. To a certain extent, Thailand does recognize the concept of dual nationality, as there are no provisions which state that the persons with dual nationality required at birth are illegal or would be punished for holding such status. However, a Thai national who holds dual status through naturalization will be considered as an alien, according to the law, they would lose Thai nationality if the Government Gazette has been published. The study finds that one of the main reasons that drives0. an individual to acquire dual nationality is the economic benefits they could gain for having dual status, including being protected under the laws and regulations of the country of their nationality and being able to gain rights and access to the resources that a national of a particular country is entitled to. At the individual level, having dual nationality is seen to be more beneficial than problematic. This contrasts with the consideration of the Thai state towards dual nationals that may abuse the advantages gained from having dual nationality in a wrong way, particularly people who are involved with transnational crimes, terrorist groups, and separatist movement which are the main threat to the national security. From this perspective, there is still a need of cooperation between Thailand and other states to deal with dual nationality issue, in order to manage and monitor the number of persons with dual nationality in Thailand and abroad for future development of the country

title: Technical efficiency and its determinants of regional hospitals in Thailand

description: Output-orientated Data Envelopment Analysis was used to measure the technical efficiency of 25 regional hospitals in Thailand from 2007-2008 as 50 decision making units (DMUs). The results revealed, there were 31 efficient DMUs from 50 DMUs for overall technical efficiency scores and a minimum was 0.810. There were 36 efficient DMUs from 50 DMUs for pure technical efficiency scores and a minimum was 0.817. For scale efficiency scores, there were 32 efficient DMUs from 50 DMUs and a minimum was 0.889. In addition, medians of all three scores were 1.000. Most of patterns of scale inefficiency were the increasing return to scale (irs:drs = 14:5). In medical education services, the results found teaching hospitals were more efficient than non-teaching hospitals and a combined undergraduate and postgraduate teaching hospital was the most efficient group. The next step was to identify the determinants of hospital efficiency with regression analysis using ordinary least squares (OLS). The results revealed if beds-physician ratio and other personnel-physician ratio decreased one unit, pure technical efficiency scores tended to increase 0.029290 and 0.008336 units respectively. If nurses-physician ratio and trained internsphysician staff ratio increased one unit, pure technical efficiency scores tended to increase 0.023639 and 0.208326 units respectively. And the most influential explanatory variable of pure technical efficiency scores was a trained interns-physician staff ratio. For scale efficiency scores, if in-patient visits adjusted with relative weight of DRG per physician increased one unit, scale efficiency scores tended to increase 0.000110 units. All above information could be used for policy makers in health sector and hospital managers improve the inefficient regional hospitals in proper direction such as most of patterns of scale inefficiency were the increasing returns to scale which can be improved through up-sizing and should supported medical education in regional hospitals which have competency. In addition, the details of each inefficient hospital should be explored and analyzed with the information from DEA and regression analyses

title: Knowledge, attitude, and practice towards childhood tuberculosis in guardians of patients visiting the Pediatric Out-Patient Department, Sirindhorn Hospital, Bangkok

description: The aim of this study was to assess the knowledge, attitudes/perceptions and practices towards childhood tuberculosis in guardians of patients at the pediatric outpatient department and well child clinic, Sirindhorn hospital, Bangkok. This study was a cross-sectional analytic study. Data were collected by using self-administered questionnaires. Four hundred participants were consented to complete the questionnaires. The results indicated that 60% of respondents had poor level of knowledge, 31% had moderate knowledge and 13.2% had good knowledge. The majority of respondents (97.8%) would talk to doctor or other medical worker about the child's illness. There were around 25% thought that the cost of diagnosis and treatment of childhood TB was expensive. There were some stigmatizing attitudes and behaviors of the community members towards the childhood TB. 22.5% of respondents reported that most people would reject the child who has TB. 2.5% would not take the patient to their home even though they completed TB treatment. There was high proportion of the poor practice compared to moderate practice and good practice. TB knowledge score was positively and statistically significantly associated with TB preventive practice score (Spearman's rho=0.315, p&lt;0.001). In multiple linear regression models, occupation (p&lt;0.001), education level (β=0.62, p=0.001) and ever knowing a TB patient (β=1.31, p=0.004) were significantly associated with knowledge score. Only ever knowing a TB patient was significantly associated with TB preventive practice score (β=0.39, p=0.004). Conclusions: Guardian education is needed. This study proposed the appropriate recommendations to improve knowledge, attitude and practice on childhood tuberculosis. Educational programs should be organized for improving knowledge especially about mode of transmission, prevention, and case detection. Influence attitude and behavioral change, especially combat stigma and discrimination

title: Removal of 2,4-dichlorophenol by fluidized-bed fenton process

description: 2,4-dichlorophenol has been widely used in the industries of dyes, pharmaceutical , pesticides and wood preservative. It is considered as a toxic and carcinogenic chemical. Therefore, the industrial wastewater contaminated with this chemical need to be treated before release to the environment. This research aims to investigate the degradation of 2,4-dichlorophenol by fluidized-bed Fenton process. In this study, Box-Behnken experiment design was applied to assess the effects of variables and determine the optimum condition. The result reveals that the initial H2O2 concentration was the main factor affecting the degradation of 2,4-dichlorophenol whereas pH, Fe[superscript 2+]and the amount of carrier were consider as less significant factors. The optimum condition for removal of 1 mM of 2,4-dichlorophenol was at pH 3, 100 grams of SiO[subscript 2] , 0.25 mM of Fe[superscript 2+]and 10 mM of H[subscript 2]O[subscript 2] which could be predicted to obtain the removal efficiencies of 99.86%, 60.49% and 14.38 % for 2,4-dichlorophenol, COD and total ion ,respectively. With comparison between Fenton and fluidized-bed Fenton process at the optimum condition, the removal efficiency of 2,4-dichlorophenol from both processes were almost the same while the higher total iron removal was found in fluidized-bed Fenton process. Since the advantage of fluidized-bed Fenton can reduce the amount of sludge via crystallization process. Moreover, the kinetic study was also investigated. The overall kinetic equation, under the studied ranges of 0.1 to 1 mM of Fe[superscript 2+], 1 to 20 mM of H[subscript 2]O[subscript 2] , 0.5 to 5 mM of 2,4-dichlorophenol , 100 grams of SiO[subscript 2] and pH 3 can be described as follows : d[2,4-DCP]/dt = 1.84x 10[superscript -1] [Fe[superscript 2+]][superscript 0.51] [H[subscript 2] O[subscript 2] ] [superscript 0.19] [2,4-DCP] [superscript 0.68]

title: A causal model of delay in seeking treatment among Thai patients with acute myocardial infarction

description: The purpose of this study was to examine the causal relationship among severity of symptom, cognitive and emotional representations, alternative coping strategies, appraisal symptom seriousness, and delay in seeking treatment among Thai Acute Myocardial Infarction (AMI) patients was based on Leventhal’s Self- Regulatory model of illness behavior. Stratified random sampling was employed to obtain the sample of 160 AMI patients who visited five hospitals in Bangkok metropolitan. Research instruments consisted of Personal Information Questionnaire, the Response to Symptom Questionnaire (RSQ) and the Coping with Heart Attack Symptom Scale (CHASS). Data were analyzed using descriptive statistics and structural equation modeling. The goodness of fit indices illustrated that delay to seek treatment model fit with the empirical data (χ2 =31.18, df = 27, χ2 /df =1.15, p = 0.26, GFI = 0.97, AGFI = 0.92, and RMSEA = 0.03), and explained 55% of the variance of delay to seek treatment. Alternative coping strategies was the most influential factor affecting delay to seek treatment through appraisal symptom seriousness by having negative indirect effects. In addition, symptom severity and appraisal symptom seriousness had a significant negative direct effect on delay to seek treatment. Cognitive illness representation had a significant negative indirect effect on delay to seek treatment through appraisal symptom seriousness. However, the emotional response to symptom was no significant to perform as directed effect on alternative coping strategies. The findings indicated the prominent components of nursing intervention focusing on reduce delay time to seek treatment by increase the likelihood and speed with which two modifiable variables appraisal of symptom seriousness and alternative were coping strategies that significance to decrease time to attribution and representation for AMI symptom. Nurses should consider about symptom severity, cognitive and emotional illness representation affecting delay to seek treatment in planning the intervention. This study highlighted important clinical, theoretical, and research implications

title: Preparation of Poly[N-Isopropylacrylamide-Co-(Maleic acid)] hydrogel mambrane by electrospinning

description: A copolymer of N-isopropylacrylamide (NIP A) and maleic acid (MA) acting as sites for the crosslinking was synthesized via free radical polymerization. Copolymer films of the synthesized copolymer by casting technique were fabricated, and then crosslinked with diethylene glycol DEG acting as crosslinker by a heat-induced esterification crosslinking reaction at 145°C. The solubility in water of the films was tested. The crosslinked copolymer film synthesit.ed from molar feed ratio of 35%mollmol (MA comonomerlNIPA monomer) in copolymerization process and W%wtlv (synthesized copolymer in ethanol) with 5%wtlwt (crosslinking agent DEG/copolymer), followed by a heat-induced crosslinking reaction was water-insoluble material. The yield of the synthesized copolymer was 55%. The copolymer was characterized by infrared and nuclear magnetic resonance spectroscopy and acid-base titration. Consequently, a new poly[N-isopropylaclylamide-co-(maleic acid)], poly(NIPA-co-MA) hydrogel membrane was fabricated by electrospinning the polymer solution. The effects of electrospinning parameters (e.g. applied voltage and distance between the needle and the collection screen) on the morphology and diameter of poly(NIPA-co-MA) hydrogel fibrous membranes were investigated by scanning electron microscopy. The range of the applied voltage studied was from 15 to 30 kV and the distance between the needle and the collection screen studied was from 10 to 25 cm. The optimal condition for fabrication of hydrogel membrane was the applied voltage ~t 25 kV and distance between the needle and the collection screen at 25 cm using a diameter of needle at 0.80 mm and the flow rate of I mL hour-I. The average diameter of electrospun fibers was I 17±33 nm. The hydrogel membrane which has esterification crosslinked was characterized by Infrared spectroscopy. The hydrogel membrane showed temperature sensitive property. Its minimum and maximum water absorption ratio was 4±0 g g-I at 50°C and 17±4 g g-I at 34 °C, respectively_ The electrospun membrane dissolved in water at the temperature below the lower critical solution temperature (LCST, 34°C), while the cast film did not

title: Application of neural network for customer lifetime value prediction : a case study in a telecommunication business

description: This thesis studies the way to treat customer relationship in the telecommunications industry. Therefore, how a person measure and manage customer lifetime value (CLV) for determining the likely future profit from the customer is very important because the customers are always looking for better and cheaper products and services. The CLV not only combines with the churn management but also considers the cross-selling and up-selling to allure customer. Earning, not just buying, customers’ loyalty is now mandatory. The method to analyze and predict customer lifetime value (CLV) using Artificial neural network (ANN) is proposed here. In this study, multi-layer perceptron (MLP) network with Levenberg-Marquardt algorithm is used to predict the CLV. Additionally, the performance of neural network is compared with decision tree using C4.5 algorithm. The accuracy of the prediction value of the neural network is 96.5%. The experiment result illustrated that the neural network model has a higher performance than the decision tree

title: Photodegradation of aqueous 2,4-Dichlorophenol under visible light using Fe-ZnO catalysts prepared by impregnation method

description: Fe-ZnO catalysts were synthesized by impregnation technique and used to test the photocatalytic degradation of 2,4-DCP under visible light. Catalyst characteristic mainly presented wurtzite structure of ZnO, with crystalline size of 35-40 nm and 5-10 m²g⁻¹ of specific surface area. Visible absorption of Fe-ZnO catalyst increased proportionally with Fe content. Oxidation state of Fe on ZnO surface was +3 and zero point charge was found at pH 9.5. Degradation experimental following Box-Behnken analysis provided an optimal condition of 2,4-DCP (initial concentration: 5.0 mg L⁻¹) degradation under visible light at 5.0 mol% Fe-ZnO calcined at 700, and catalyst loading of 1.5 g L⁻¹ (volume of synthetic waste water). Besides, the addition of 2 mM potassium persulfate (K₂S₂O₈) could increase the degradation efficiency and the reaction could be completed within 90 min. The degradation performance on Fe-ZnO combined with K₂S₂O₈ was 5 times higher than that using ZnO combined with K₂S₂O₈. Reaction kinetics was fitted very well with the Langmuir-Hinshelwood model
