title: Factors inducing anxiety and depression among adult Myanmar migrant workers : a case study in Ratchaburi province, Thailand

description: This study was conducted in March 2011 to describe the independent variables composing of demographic factors, socio-economic factors, educational background and behavioral factors and to access the association of these independent variables with the dependent variables (anxiety and depression) among adult Myanmar migrant workers in Ratchaburi province, Thailand. This study was carried out only among adults Myanmar migrant workers because adults are more mature who can manage their frustration better than the teenagers. The data was collected by face-to-face interview questionnaire. The majority of the respondents were in the age of 25-35 years old and three hundred Myanmar migrant workers were participated in this study. Fifty-five percent of the respondents were males and forty-five percent were females. Most of the respondents were singles, Myanmar, full time workers and about half of them attended primary school. Most of the respondents lived together with their friends and relatives, some lived with their family. Thirty-two percent of the respondents were drinking and 18.7% were smoking. About two thirds of respondents were having marked to severe anxiety level (64.3%) and majority of respondents were having mild depression (42.7%) and moderate depression (36.7%). In bivariate analysis, living status was associated with depression (p&lt;0.05). All other factors were not associated with anxiety and depression. A strategy for the mental health for these groups should be seen as a strategic investment which will create many long term benefits for individuals, societies and health systems. Professions in mental health such as psychologists, psychiatric nurses and social workers should receive special training for appropriate knowledge and skills among migrant workers.

title: Molecular characteristics of multidrug resistant Salmonella enterica isolated from humans and pork

description: Total of 183 Salmonella enterica isolates from humans (n=52) and pork (n=131) were included. All isolates were detected for antimicrobial susceptibilities, the presence of class 1, 2 and 3 integrons, antimicrobial resistance genes and virulence genes. The ciprofloxacin-resistant isolates (n=24) were tested for the presence of mutations in gyrA, gyrB, parC and parE and AcrAB-TolC expression. Genetic relatedness of the selected strains (n=40) was examined by multilocus sequence typing (MLST). Most isolates were resistant to tetracycline (73%), followed by ampicillin (53%). None were resistant to ceftriaxone. Thirty-nine percent were positive to intl1, of which 15% carried gene cassettes i.e. dfrA12-aadA2, bla[subscript PSE-1] and aadA2. Two Salmonella isolates carrying class 1 integrons with dfrA12-aadA2 could horizontally transfer their integrons. None were positive for int2 and int3. SGI1-G and SGI1-F were detected in an Albany and a Kedougou, respectively. Eighteen resistance genes were found in the Salmonella isolates with corresponding resistance phenotype. All isolates carried the virulence genes invA, msgA, spiA and tolC. The spvC and pefA gene encoded by Salmonella virulence plasmids were present at limited rate. The amino acid substitutions Met-48-Ile and Thr-82-Met were most common in GyrA and ParC, repectively. The acrB expression level varied from 1 to 430 folds and was not associated with ciprofloxacin MICs. Based on the MLST results, most of the pork and human isolates with the same serovars were grouped into the same clusters, providing evidence that pork could serve as a reservoir for Salmonella in humans.

title: The ultimate ownership of family firms and real earnings management : empirical evidence from Thailand

description: This study examines, firstly, the association between family ownership structure and real earnings management and, secondly, investigates whether different degrees of cash flow-control rights divergence of family ownership affects real earnings management. Three types of real operating manipulation are considered: sales manipulation, production manipulation, and discretionary expense manipulation. Family ownership is defined based on the ultimate control rights. The unique data set covers 577 firm-years observation based on Thai listed company data from the Stock Exchange of Thailand (SET) over the period 2008-2010. Given the inconclusive extant studies based on two competing notions: the alignment effect and the entrenchment effect, the directional relationship between family ownership structure and real earnings management is predicted with no direction. In contrast, the high degree of divergence allows family shareholders to have relatively low committed cash flow compared to their control right, thus inducing entrenched motivation for family owners. This study hypothesizes that the degree of cash flow-control rights divergence of family firms is positively associated with the level of real earnings management. Consistent with the hypotheses this study, firstly, finds that firms with (without) ultimate family shareholders are more (less) likely to engage in real earnings management. This association is found only in sales manipulation activity and the manipulation is an upward direction. Secondly, this study finds that family firms with a higher (lower) degree of cash flow-control rights divergence are more (less) likely to engage in real earnings management. The real earnings manipulation is employed through sales manipulation in an “upward” direction and discretionary expense activities in both upward and downward directions. Overall, family firms with different degrees of cash flow-control rights divergence perceive costs associated with each manipulation activity differently.

title: The characterization of immune response in patients with viral hapatitis B infection

description: Hepatitis B infection is a major cause of liver diseases. Approximately 2 billion people worldwide and 400 million of them remain chronically infected. Defect or exhausted innate and adaptive immune responses lead to HBV persistence. It is believed that the vigorous and multispecific T-cell response are important to viral control in resolved HBV infection. Here, we firstly identified novel HLA-C-restricted CTL epitope of HBV antigen from resolved patient. The specific CTL response to amino acids 171-180 of envelope antigen restricted to HLA-Cw*08:01 molecule revealed responsiveness in 53% of tested patients with resolved HBV infection. The cross-activity of this CTL response was detected in HBV genotype B and C. The comparative specific CTL response against Env171-180 versus the known-HLA-A or -B-restricted epitopes indicated that the frequency and magnitude of HLA-Cw*08:01-restricted Env171-180 response are greater or at least comparable to known HLA-A*02, A*11, A*24 and B*51 restricted CTL responses. Moreover, we investigated whether gene expression patterns in peripheral blood mononuclear cells (PBMC) were different between sustained virological responder and non-responder to Pegylated-interferon alpha in chronic HBV infection with positive or negative HBeAg. The Illumina Sentrix Humanref-8 v2 BeadChips microarray was used for the analysis of global gene expression. We found that most of the significantly different genes were at higher level in the responder compared to the non-responder groups both at pretreatment and/or during treatment at week 24. Some interesting immune-related genes are previously reported to have anti-viral activity such as response to virus (IFI16, MX1, MX2), viral defense or viral genome sensor (GBP3, IFI16), regulation of viral reproduction (APOBEC3F) and proteasome (PSMB8). Another factor which influences the chronic status of HBV infection is host factor. Several polymorphisms of immune genes, such as cytokine genes, were previously reported to be individually associated with disease progression; however, the analysis of these polymorphisms together as the combination of Th1 and Th2 genotypes has never been investigated. In this study, twenty-two polymorphisms of cytokine and cytokine receptor genes were studied for their association with the risk of chronicity. Although the combined analysis of the role of Th1 and Th2 genotypes gave no positive association with chronic hepatitis B infection. Our genotype data showed that the patients with low IL-10 as well as low IL-4 producing allele has lower risk for chronic state suggesting a protective role of Th2. Taken together, host factors affect the distinct immune responses resulting in the different clinical outcomes of HBV infection. The more information in HBV pathogenesis and immune response is necessary for the further development of novel therapy for chronic HBV infection.

title: Working environment and respiratory problems among employees in 2 garment factories in Ubon Ratchathani province

description: This study aimed to identify workplace environmental factors associated with prevalence of respiratory symptoms among employees in 2 garment factories in northeastern Thailand. Sociodemographic and behavioral factors were also examined. The study included 380 workers (excluding administrators). Respiratory symptoms included cough, phlegm, difficulty breathing, shortness of breath, chest tightness, wheeze, and rhinitis. Symptom prevalence was consistently higher at one factory (factory B) than the other (factory A). Factory A had air ventilation, whereas factory B did not. Also, presence of visible dust was more pronounced, and a higher proportion of workers sewed cotton fabric (as opposed to other types such as polyester), at factory B than factory A. Workers at factory B had also worked longer than those at factory A. Among sociodemographic factors, female gender was consistently associated with elevated prevalence. Surprisingly, smoking was not associated with increased respiratory symptom prevalence, possibly due to confounding in the data. Study results suggest strongly that workplace environmental factors are associated with symptom prevalence in garment factory workers. However, because multivariable analysis was not conducted, the specific contributions of individual factors could not be compared with confidence. Further research on this topic is needed to inform policies that will ensure the safety of garment workers in Thailand.

title: Strong law of large numbers for a 2-dimensional array of pairwise negatively dependent random variables

description: In this work, we obtain two main theorems of strong law of large numbers for a 2-dimensional array of random variables. The first theorem is the strong law of large numbers for pairwise negatively dependent random variables which are not necessary identically distributed. The second theorem, we obtain strong law of large numbers for the difference of random variables which independent and identically distributed conditions are regarded. In this study, we use the limit as m×n tends to infinity instead of using the limit as m,n tends to infinity when m,n are natural numbers which is stronger.

title: Circulating serotonin concentrations in dogs with degenerative mitral valve disease

description: Serotonin mediating valvular disease is widely known in human medicine, but it is still unclear in canine degenerative mitral valve disease (DMVD). The Purpose of this study was to compare circulating serotonin concentrations between normal dogs and dogs with DMVD. Twenty healthy and twenty-three newly confirmed DMVD dogs, small breed less than 10 kilograms and older than 7 years old, were collected for the blood samples. Serum, plasma and platelet serotonin concentrations were measured by the serotonin ELISA test. Median plasma and platelet serotonin concentrations were not significantly different between the normal dogs and dogs with DMVD. While, median serum serotonin concentration in dogs with DMVD was significant lower than the normal dogs (p &lt; 0.01). Age, platelet count, and echocardiographic indices showed no significant correlation with the circulating serotonin concentration. From the plasma and platelet results, the serotonin concentrations were unchanged between normal and DMVD group. Even though the difference had found in serum serotonin concentration, the serum sample does not represent the real circumstance in the body. In conclusion, circulating serotonin is unlikely to be a major source of serotonin in DMVD. Local serotonin signaling is suggested in mediating canine DMVD. Further study about the local serotonin blockage or other serotonin pathways mediating DMVD is warranted.

title: The effect of screw tightening methods on screw loosening resistance in implant-abutment connection of 2 implant systems

description: The propose of this study was to compare the effect of 3 screw tightening methods on screw loosening resistance. The 2 implant systems (CU dental implant and SimpleLine II were used in the study (N=30).The implant bodies were embedded in the acrylic blocks.The abutment screws were tightened to the manufacturer’s recommended torque using 3 tightening methods as following; method1: tightening the screw 1 time, method2 tightening the screw, wait for 10 minutes, retightening the screw, method3: tightening the screw, wait for 3 minutes,loosening the screw, retightening the screw, wait for 10 minutes, retightening the screw. The fatigue loading was applied.The reverse torque values were measured. Kruskal-Wallis and Conover-Inman were used to compare the reverse torque value in the percentage of initial tightening torque. The method1 showed the significantly lowest screw loosening resistance in 2 implant systems (p&lt;0.05). The method 2 and the method 3 showed no significant difference on screw loosening resistance in 2 implant systems.When comparing between 2 systems. SimpleLine II showed higher screw loosening resistance than those of the CU dental implant significantly (p&lt;0.05).It can be concluded that the highest reverse torque values could be achieved by screw retightening,and the screw loosening before the screw retightening did not increase the reverse torque values to be higher than those achieved from the first screw retightening. SimpleLine II showed the significantly higher screw loosening resistance than CU dental implant.

title: Effect of complete denture occlusal schemes on masticatory performance and maximum occlusal force

description: The aims of this study were to evaluate the effect of two complete denture occlusal schemes on masticatory performance and maximum occlusal force. Two complete dentures occlusal schemes, bilateral balanced occlusion and neutrocentric occlusion, were randomly delivered to 10 fully edentulous subjects (6 males and 4 females with the mean age of 67.3 years old), were referred to graduate prosthodontic clinic at Faculty of dentistry, Chulalongkorn University. The masticatory performance and the maximum occlusal force were obtained using multiple sieve method and pressure sensitive film respectively. Two occlusal schemes were interchanged on the intra-individual denture base. The tests were repeated similarly. Results showed both occlusal schemes demonstrated no significant differences on masticatory performance (p=0.07). The increasing of chewing strokes of both occlusal schemes showed significant differences on masticatory performance (p&lt;0.001). Both occlusal schemes demonstrated no significant differences on maximum occlusal force (p=0.31). In conclusion, complete denture with bilateral balanced occlusion and neutrocentric occlusion demonstrated no significant differences on masticatory performance and maximum occlusal force. However, the more chewing strokes showed better masticatory performance. For clinical implication, Neutrocentric occlusion rendered the same masticatory performance and maximum occlusal force as the golden standard bilateral balanced occlusion. However, the complete denture wearers should be instructed to apply more chewing strokes for a better chewing ability.

title: The study of unit cost and quality of education of Ghazanfar Institute of Heatlh Science (GIHS) and private institutes in Kabul province from 2009 to 2012

description: This study is a descriptive type of research that contains two parts, a calculation of the unit cost or cost per graduate student and an assessment of the quality of education of nursing, midwifery, pharmacy, technology, physiotherapy, radiology, dentistry and anesthesia disciplines in GIHS and 5 private institutes of health science in Kabul province. The average cost calculation in GIHS is done from the provider perspective including donor support for GIHS and accommodation, while the average unit cost in private institutes is calculated from the purchaser perspective. The study finds the average unit cost of nursing to be equal to US$ 4,231, midwifery US$ 6,404, pharmacy US$ 6,796, technology US$ 5,705, physiotherapy US$ 5,329, radiology US$ 6,106, dentistry US$8,015, and anesthesia US$ 1,074 for the whole period of the study in GIHS while this average cost amounts US$ 1,590 for nursing, US$ 1,409 for midwifery, US$ 1,425 for pharmacy, US$ 1,216 for technology, and US$ 1,216 for dentistry in private institutes from the purchaser perspective for the whole period of the study. When excluding the accommodation cost of GIHS, the unit cost of nursing decreased to US$ 1,816, midwifery to US$ 4,852, pharmacy to US$ 2,809, technology to US$ 3,505, physiotherapy to US$ 4,308, radiology to US$ 3,379, dentistry to US$2,948 and anesthesia to US$ 1,133. The study shows that the unit cost in GIHS is at least twice as much the unit cost in private institutes in some disciplines, which is mainly due to the high cost of accommodation, donations and the low output of disciplines in terms of number of graduate students. In terms of quality of education, however, the findings show that the quality of education is perceived to be better in GIHS, especially in terms of practical work due to the availability of public facilities to GIHS, according to the in-depth interviews with officials from MoPH and lecturers from GIHS and private institutes. The student survey on the other hand interestingly indicates that the quality of education is better in private institutes than GIHS. In general the study findings reveal that GIHS cost needs to be decreased or output per discipline increased and that the quality of practical work in private institutes needs to be improved.

title: Optimal design of steel structures using heuristic algorithm with direct analysis method

description: This study proposes a Heuristic Algorithm for the optimal design of steel frame structures using the Direct Analysis Method of the AISC 2010 Specification. The objective of the design algorithm is to obtain the minimum weight of the steel frame sections where the design constraints are imposed by the AISC-LRFD specification requirements. In this paper we combine the CSi SAP2000 commercial structural analysis program with the Heuristic Algorithm which is written in Microsoft Visual Basic program for the optimal design of steel frame structures. The analyses are performed by using the first-order analysis method without P-Delta effects and the rigorous second-order analysis with P-Delta effects to illustrate their effects on structural optimal design. Through three examples of planar steel frames, we firstly compare the results between the Direct Analysis Method and the conventional methods which are the Effective Length Method and the First-Order Analysis Method, and then followed by the comparison of the efficiency of the Heuristic Algorithm with the optimization algorithm such as Genetic Algorithm, Ant Colony Optimization, Harmonic Search algorithm, and the virtual work based optimization for lateral deflections in software CSi SAP2000.
