title: Effects of aquatic exercise and land-based exercise on postural sway in elderly with knee osteoarthritis

description: Objectives: The objective of this study is to compare effects of aquatic exercise and land-based exercise on postural sway and physical performance in elderly with knee osteoarthritis. Methods: The assessor-blinded randomized controlled trail was done. Elderly women with mild to moderate osteoarthritis, age 60-75 yrs were recruited. Postural sway viewed by COPx or anterior– posterior (A–P) amplitude, COPy or medio– lateral (M–L) amplitude, Total Area or XY area in during double and single leg stance while eyes opened and closed measured by the Force platform (Bertec # FP 4060-08), functional outcome tested by Modified WOMAC and Knee injury and Osteoarthritis Outcome Score (KOOS), pain scale tested by Visual Analog Scale (VAS), leg muscle strength tested by chair stand, and leg muscle flexibility tested by sit and reach test were measured before training as baseline and 6 weeks after training. The patients were randomized into two groups. Aquatic group exercised in therapeutic pool of King Chulalongkorn Memorial Hospital and Land-based group exercised at home, 45-60 minutes per day, 3 times a week, for 6 weeks. Results: The reduction of postural sway in aquatic group was significantly more than land-based group at p &lt;0.05. ANCOVA showed that WOMAC, KOOS scores and sit and reach test after 6 weeks training were significantly improved after exercise in both group but were not significantly different between groups at p &gt; 0.05, except that chair stand was significantly increased and VAS was significantly decreased in the aquatic group more than the land-based exercise group at p &lt;0.05. Conclusion: Aquatic exercise for 6 weeks was better than land-based exercise for 6 weeks in term of sway reduction, pain reduction and strength increment but not the functional outcome and muscle flexibility.

title: The development of an English writing course based on the genre-based approach for undergraduate Engineering students at King Mongkut's University of Technology North Bangkok

description: The study objectives were (1) to investigate the needs of English writing skills of operational and managerial engineers, (2) to develop an English writing course based on the genre-based approach to enhance English writing achievement of undergraduate engineering students, (3) to determine the effectiveness of the English writing course developed based on the genre-based approach, and (4) to explore the engineering students’ attitudes toward the developed English writing course. The study was descriptive and experimental research involving three phases: needs analysis, course development, and course implementation. The needs analysis was conducted using a questionnaire and an interview protocol as the research instruments. In the first phase, the questionnaires were distributed to the three groups of subject, namely, 129 engineers, 354 engineering students, and 31 ESP teachers. The results revealed three genres were most required in engineering work (request e-mails, enquiry e-mails, and investigation reports). Next, two managerial engineers and ten operational engineers were interviewed to gather in-depth information about writing contexts and situations of engineering associated with each required genre. In the second phase, the course was developed based on the GBA course development stages and the data derived from the needs analysis. In the third phase, the course was implemented for 12 weeks with 25 undergraduate engineering students who were enrolled in the English for Engineers course at King Mongkut’s University of Technology North Bangkok. To examine the effectiveness of the course, pre-test and post-test scores were compared. Also, the students were interviewed. The attitude questionnaire and student logs were used to determine the students’ attitude toward the developed course. The findings revealed that the course was effective since it was found that the post-test scores of the students were significantly higher than the pre-test scores. In addition, the students also had positive attitudes toward the course. Based on the findings of the study, it is recommended that more genre-based English courses for engineering students and students in other disciplines should be developed

title: Species and Antimicrobial Susceptibility of Methicillin-Resistant Coagulase-Positive Staphylococcus spp. (MRCPS) isolated from dogs in Thailand

description: The objective of this study was to screen prevalence and antimicrobial susceptibility of Coagulase positive Staphylococcus spp. (CPS) isolated from dogs visiting at the Small Animal Hospital of Chulalongkorn University. Staphylococcus spp. were identified by using of gene detection and PCR-REA technique. In addition, mechanism of methicillin resistance was determined by molecular detection of their resistance genes. 200 samples from both nostril, wound or otitis externa were obtained from 100 dogs. 72 isolates from 200 samples (36%) were found to be Staphyloccoci. Among ofthese , 49 isolates (68.05%) were identified as CPS. The highest prevalence occurrence of CPs found in this study was in nasal cavity, followed by wound and otitis externa, respectively. The PCR technique for molecular detection revealed that S. pseudintermedius was the most common CPS (85.71%) found in dogs. The antimicrobial susceptibility test showed that most of CPS were susceptible to mupirocin (93.88%) whereas few of them were susceptible to cefalexin (2.04%). Moreover, 88% CPS isolates were multidrug resistant (more than 3 drugs) and most of the MDR-CPS resisted more than 4 antimicrobials. The MIC [subscript 50] and MIC[subscript 90]of oxacillin against MDR-CPS were 256 mug/ml. Most of S. pseudintermedius isolates resisted to oxacillin (MIC &gt; 4 mug/ml) whereas no oxacillin resistance of S. aureus and other CPS were found (MIC &lt; 2 mug/ml). No correlation between beta-lactamase screening test and the presence of the resistant gene blaZ and mecA was found in this study. The molecular identification revealed that 22 out of 49 isolates carried both blaZ and mecA gene and their MIC of oxacillin were also higher than those against the isolates carried either blaZ or mecA genes. Most of S. pseudintermedius isolates carried both blaZ and mecA genes. Two out of three S. aureus isolates found in this study carried either blaZ while the other CPS did not carried blaZ or mecA genes. The results from this study showed that the most common of methicillin resistant CPS found in dogs was S. pseudintermedius. These isolates were highly resistant to many antimicrobials, including cefalexin which is commonly used in veterinary practice. Unfortunately, most of them were blaZ and mecA genes carrier. Eventhough, MRSP in people is only a minor concern, the methicillin resistant gene can transmit to the other Staphylococcus spp. including S. aureus that can be the cause of the MRSA spread in the community

title: Effects of lightness and chroma on colour harmony of colour pairs

description: In addition to quality and usability of products, colour is an important factor which affects a customer’s decision when buying a product. Designers should therefore consider a combination of colours in order to design most outstanding and pleasing products. This study aimed to investigate impacts of lightness and chroma of colour pairs on the degree of perceived colour harmony. Colour samples were divided into 2 sets: 42 single colours were chosen for the lightness investigation, and 33 single colours for the chroma. All possible combinations of single colours were generated to obtain 861 and 528 colour pairs, respectively. The colour pairs were shown one by one on a CRT monitor as two colour squares placed next to each other against a uniform grey background. Twenty Thai observers, all having normal colour vision, participated in the experiments in which they were asked to rate the degree of colour harmony for each colour pair using a 10-point scale (-5 means completely disharmonious to 5 means completely harmonious). Experimental results indicated that lightness and chroma had impacts on colour-harmony scores of colour pairs. Colour pairs with high lightness were more harmonious than those with low lightness and similar results were also found in the case of chroma. The most harmonious colour was white and the grey was the most disharmonious

title: Effects of individualized environmental modification program on neurobehavioral organizations of the very low birth weight infants

description: This study was aim to evaluate the effects of individualized environmental modification (IEM) program on neurobehavioral organizations of VLBW infants who admitted in neonatal unit. Twenty-five preterm infants weighing less than 1500 g. and born before 37 weeks' gestation were studied. All infants were served as their own control which received conventional nursing care during control period. IEM program was provided during experimental period which consists of day-night lighting, classical music playing and lavender smelling. The activities were adjusted to the appropriate level of intensity and duration based on each infant's responses. Naturalistic Observation of Newborn Behavior (NONB) was used to observe infants' neurobehavioral organization at baseline, control period and experimental period. Descriptive statistic was used to analyze infants' demographic data. Repeated measures ANOVA was used to compare mean different of neurobehavioral outcomes of infants between control period and experimental period. The research results showed that infants in experimental period had significantly showed better positive autonomic responses, positive motoric behaviors and positive attention behaviors comparing to control period. Additionally, infants in the experiment period sleep longer and spent fewer times in transitional and arousal states than in the control period. In conclusion, VLBW infants were benefited from IEM program in term of neurobehavioral organization. Promotion of VLBW infants' neurobehavioral organization admitted in a sick newborn unit can be implemented by integrated the IEM program in a routine nursing care for VLBW infants

title: Comparative analysis of EU demand for Thai tourism

description: This paper studied the determinants of European demand to Thai tourism, estimates the elasticities of demand – the price elasticity, the income elasticity and the cross-income elasticity - and also explored the dynamics of those elasticities over the sample period of 1996Q1-2008Q4. To estimate the elasticities of tourism demand, the cointegration analyses – the Engle-Granger (EG) method and the Johansen Cointegration Test – were employed. In additional to the two approaches, the Rolling Regresssion and the Recursive Ordinary Least Square (OLS) were utilised as analytical tools to investigate the dynamics of the European demand to Thai tourism. The samples in this study were divided into two groups – 11 country models and 3 income-group models. Concerning empirical results, the price elasticity was found to be inelastic both in the country models and in the income-group model, according to the two means of estimation. Meanwhile, the income elasticity in two groups of samples, either in the country models or the income-group model, was found to be elastic or highly elastic. This was in line with empirical evidence suggested by the existing empirical literature. The cross-price elasticities were found to be mixed depending on the competitive destinations. Regarding the dynamics of the price elasticity overtime, for both the country models and the income-group models, were found to be inelastic and approaching zero, whereas those of the income elasticity were found be elastic and increasing overtime. Based upon these findings, following policy recommendations were concluded. Firstly, on the policymakers’ front, low tourism strategies were unlikely to be effective in attracting more European tourists and increasing tourism receipts given the inelastic price elasticity. Policies promoting Thailand’s images as a tourism destination meeting European holidaymakers’ motivations for travelling should be implemented. This was due to the fact that the habit persistence or the so-called word-of-mouth effects was a crucial and significant determinant of European demand to Thai tourism. On the other hand, for the Thai tourism entrepreneurs, they could increase some certain degrees of tourism products in order to gain more revenues with losing significant number of visitors. Secondly, provided the findings of the income elasticity, the Thai tourism sector was exposed to shocks affecting income levels of the tourism-generating countries and those were unpredictable. The best strategy to minimise uncertainties was to promote and create Thailand to be a “must-go tourism destination” as a mean to generate tourism income in the long-run.

title: RGB values of B-10 milk biofilms on stainless steel coupons

description: The fluorescence micrographs of EtBr-stained B-10 milk biofilms on stainless steel coupons (SSCs) were analyzed using the ImageJ 1.52a software. The RGB values obtained were in decreasing manner when comparing before and after the immersion in 100 mg/ml of P-03 (an unknown species of Pestalotiopsis) culture crude extract at 50 degrees Celsius for 15 min followed by EtBr (ethidium bromide) staining. The results suggest that the recorded intensity (CPS) of light emitted by the EtBr stained the extracellular matrix (ECM), which covered the B-10 milk biofilms, was disrupted. The values also showed in the 3-D plot surface generated by the software. ECM degradation is one of the key to biofilm control. The P-03 crude extract has antimicrobial property with MIC of 6.25 mg/ml. Degrading the ECM will kill the exposed B. cereus s.l. biofilm cells, but not the spores, by the fungal crude extract and therefore a possible alternative antibiofilm agent.

title: MassIVE MSV000084241 - Proteomic profile of human Schwann cells
title: Schwann cells (SC) are essential to the growth, maintenance and regeneration of peripheral nerves, but the proteome of normal human SC is poorly defined. Here, we performed a proteomic analysis by liquid chromatography tandem mass spectrometry (LC-MS/MS) to identify the protein expression profile of primary human SC. A total of 19,557 peptides corresponding to 1,553 proteins were identified, with 1% false discovery rate (FDR). Ingenuity Pathway Analysis (IPA), Gene Ontology (GO) and Database for Annotation, Visualization and Integrated Discovery (DAVID) were used to assign protein localization and function, and to define enriched pathways. EIF2, mTOR and integrin signalling were among the most enriched pathways and the most enriched biological function was cell-cell adhesion, which is in agreement with the supportive role of SC in peripheral nerves. This proteome analysis of normal human SC may help in the molecular exploration of neurological and malignant diseases where SC are involved.

title: Toluene oxidation by hydrogen peroxide at elevated temperature over modified TS-1

description: This research studies the oxidation of toluene by hydrogen peroxide using titanium silicalite-1 catalysts modified with different amount of Al at the reaction temperatures higher than the boiling point of water at atmospheric pressure. All catalysts are characterized by X-ray Fluorescence Spectroscopy (XRF), X-ray Diffractometer (XRD), Fourier Transform Infrared Spectrometer (FT-IR), nitrogen adsorption (Brunauer-Emmett-Teller - BET) and Temperature Programmed Desorption of ammonia (NH3-TPD). The parameters studied in this work are amount of aluminium, reaction temperature and hydrogen peroxide per toluene molar ratios. This study found that the addition of Al into TS-1 does not destroy the structure of TS-1. Furthermore, addition of Al promotes the formation of benzaldehyde. All modified catalysts yield benzaldehyde as the major product with a small amount of o-cresol and p-cresol as by-products. The experimental results also show that increasing of the reaction temperature increases the reaction rate. However, the conversion of H2O2 may increase only slightly or decreases in some cases. In addition, increasing molar ratio of H2O2 per toluene increases benzaldehyde formation.

title: Value investing in Stock Exchange of Thailand (SET) : Financial signals vs growth in EPS

description: The primary objective of this paper is to examine value and growth stocks in Stock Exchange of Thailand, based on 1995 to 2007, in order to investigate the assertion that value stocks on average generate higher returns than growth stocks based on numerous considerable evidences suggested that on average value investing strategy outperforms growth investing strategy. This paper uses average returns, Jensen’s alpha and Sharpe ratio as a measurement for portfolio efficiency. The result shown that value portfolio could generate higher returns than growth portfolio by approximately 24% annually on portfolio sorted by B/M, E/P, and C/P in both big and small market capitalization. Further, the portfolio returns could be enhanced by approximately 4.3% annually when applied financial signals to discriminate a value firm with strong financial prospect and a value firm with poor financial prospect in order to construct a portfolio that generate a superior return than a conventional value investing strategy. Finally, this paper examines a style investing strategy through using growth in EPS characteristic incorporated with a value stocks in order to investigate whether a dual-characteristic investing strategy of high earnings yield together with high growth in EPS (HEHG) could outperform other investment strategies. However, the result indicates that although high earnings yield with high growth in EPS could generate higher returns other style investing strategies; high earnings yield with low growth (HELG), low earnings yield with high growth (LEHG), and low earnings yield with low growth (LELG), with the difference of 11% (10%), 17% (22%), and 22% (30%), respectively, in big (small) market capitalization; but when compared HEHG with financial analysis approach it seems that HEHG strategy could not outperform financial signals strategy in term of Jensen’s alpha and Sharpe ratio.

title: 3D captcha : a new generation of captcha

description: Nowadays, the internet is now becoming a part of our everyday lives. Many services, including Email, search engine, and web board on internet, are provided with free of charge and unintentionally turns them into vulnerability services. Many software robots or, in short term, bots are developed with purpose to use such services illegally and automatically. Thus, web sites employ human authentication mechanism called Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) to counter this attack. Unfortunately, many CAPTCHA have been already broken by bots and some CAPTCHA are difficult to read by human. In this thesis, a new CAPTCHA method called 3D CAPTCHA is proposed to provide an enhanced protection from bots. This method based on the assumption that human can recognize 3D character image better than automated program bots. Moreover, this thesis also introduces the 3D - animation CAPTCHA method to increase protection from bots. This method includes multiple image frames instead of using a single frame found in general CAPTCHA

title: A causal model of physical activity in healthy older Thai people

description: To develop and examine the causal relationships among self-efficacy, positive outcome expectation, negative outcome expectation, age, social support, physical environment, and physical activity among older Thai people. The sample, 320 Thai older people aged 60 years and over who resided in twelve communities within 6 sub-districts of Thailand was obtained by multi-stage random sampling. Research instruments were a personal data sheet, the Chula mental test, the positive outcome expectations for physical activity, the negative outcome expectations for physical activity, the self-efficacy for physical activity, the social support for physical activity, the environment supports for physical activity, and the physical activity questionnaires. Data were analyzed using descriptive statistics and structural equation modeling. The goodness of fit indices illustrated that the physical activity model fit with the empirical data, and explained 65% of the variance of physical activity in healthy older Thai people. Self-efficacy was the most influential factor affecting physical activity both direct and indirect effects through negative outcome expectations. Positive outcome expectation, age, and physical environment had a significant direct effect on physical activity. Social support had a significant indirect effect on physical activity through self-efficacy. However, the positive outcome expectation was no significant to perform as directed effect from self-efficacy to physical activity. The study suggested that the physical activity model can explain physical activity in healthy older Thai people. The further interventions should be concerned about enhancing self-efficacy reducing negative outcome expectation reducing negative outcome expectation reducing negative outcome expectation, motivating social support, and providing physical environment to increase the physical activity of healthy older Thai people

title: Relationship between dietary pattern and matabolic syndrome in population in Mueang distric Nakhon Ratchasima province

description: The purpose of this study was to test reliability and validity of the KDQOL-SFTM version 1.3 by focus on kidney disease targeted items. Subjects were 191 outpatients with renal replacement therapy. Practicality was assessed with average time of administration and floor and ceiling effects. Reliability was evaluated by using intraclass correlation coefficients (ICCs) for test-retest reliability assessment with telephone interview and Cronbach’s alpha for internal consistency. Construct validity was supported with convergent and discriminant validity using correlation among SF-36, EQ-5D, overall health rating scale score, sociodemographic parameter and kidney disease targeted scores. Multitrait scaling method was used to test construct validity and known-groups validity that referred to ability to distinguish among dialysis and transplant patients. It was found that average time of administration approximately was 23 minutes. Cronbach’s alpha in dialysis and transplant groups ranging from 0.44 to 0.86 and 0.43 to 0.84, respectively. ICCs ranging from 0.531-0.952. There were significantly low to moderate correlations among SF-36, EQ-5D, overall health rating scale scores and kidney disease targeted scores. The direction of correlation between sociodemographic parameter and kidney disease targeted items was presented as hypothesis. Success scaling of convergent and discriminant validity in dialysis and transplant groups were 74.17% and 88.81%, 83.83% and 86.59%, respectively. In addition, the KDQOL-SFTM scores discriminated among dialysis and transplant groups (p&lt;0.05). Conclusion, the KDQOL-SFTM version 1.3 has acceptable reliability and validity to be use to assess the health-related quality of life in renal replacement therapy Thai patients
