title: The four score compared glasgow coma scale to evaluate the patients with intubation at emergency room

description: Background: The level of consciousness of patient is important at emergency room for a treatment plan quickly and efficiently. Many tools have been developed to evaluate various ways to help in assessing the limit of GCS score. One of them is the FOUR (Full Outline of UnResponsiveness) score, new coma scale, evaluates 4 components: eye and motor responses, brainstem reflexes and respiration pattern. Therefore this study was to compare FOUR score and GCS for use in patients with intubation in the emergency room. Method: 80 patients with intubation at ER have evaluate by random pair of rater ( ED Residents, ED Nurses, Extern on duty at ER) both FOUR and GCS score in each patient and tracking information until the patients are discharged from the hospital. The statistical of study used Willcoxon’ s sign rank test to determine differences between group, Spearman’s and Kendall’s correlation to determine correlation between FOUR and GCS , weighted kappa and ICC to determine the degree of agreement and the logistic regression for in-hospital death. Results: Inter-rater agreement were good to excellent for FOUR score ( Kw =0.80, ICC= 0.96, 95%CI 0.93-0.97) and GCS score (Kw=0.83, ICC= 0.92, 95%CI 0.96-0.98) and there were no statistical significant differences between rater types. The score’s correlation was good ( r=0.82, T=0.74, p&lt; 0.01). Every 1-point increase in total scores, there were reduction in odds of in-hospital mortality (FOUR: OR= 0.87, 95% CI 0.67- 1.10 ; GCS: OR= 0.91, 95% CI 0.57- 1.45). Conclusion: The FOUR score is reliable for evaluate the patient with intubation at ER. The FOUR score can be used to predict in-hospital mortality.

title: The computational model of synaptic plasticity in area ca1 of hippocampus

description: Long-term Potentiation (LTP) is the best characterized forms of enhancement in synaptic plasticity which is a widely accepted model of learning and memory. The modification of long-term plasticity is a complex process and varies throughout synaptic events. The present research, in vitro brain slice techniques were used to study the efficacy of tetanic stimulation and theta-burst stimulation (TBS) for LTP induction in rats. In addition, the study also investigated the effects of cortical spreading depression (CSD), picrotoxin-an antagonist of gamma aminobutyric acid A (GABAA) receptor on the tetanic-induced LTP. For results of efficacy of stimulate patterns, the stimulation intensity was 0.37+0.0677V with tetanic stimulation and 0.31+0.0862V with TBS. There were no significant differences among groups (one-way ANOVA, P=0.122). TBS effectively induces LTP more than tetanic stimulation with 144.42±6.54% of baseline (N=10) and 134.88±6.92% of baseline (N=10), respectively. In addition, the picrotoxin effectively induced LTP with 140.25±4.18% of the baseline in the picrotoxin group (N=8) versus 134.88±6.92% of the baseline in the control group (N=10). In group with picrotoxin applied to CSD, we obtained the smallest magnitude of LTP (120.15±3.73% of the baseline, N=8). The experimental data were interpreted by least squares curve fitting which modeled as three mathematical equations, polynomial, exponential and power equations. I found that the model of power equation produced the best in adjusted value and initial post-tetanic potentiation approximation. For LTP approximation, there were similar quantification that the polynomial model produced a small relative error with abundant residual while there were not many residual from the exponential model and power model. Therefore, the power equation was a suitable model for LTP approximation or description of synaptic response. More over the nonlinear attribute of LTP had an influence on the fitting, with respect to increasing the accuracy of the parameters and the compatibility of combination of stimuli that produce LTP.

title: Aphid dispersal between siam weed and cabbage under interaction with ant in Wiangsa District, Nan Province

description: The potential of Siam weed serving as aphid reservoir for aphid dispersal to crops was investigated during August 2010-September 2011 in Wiangsa District, Nan Province. Siam weeds and cabbages were sampled for species diversity and abundance of aphids and other arthropods, such as tended-ants and natural enemies, in forest, commercial cabbage fields, and a field experiment of cultivating mixture of Siam weed and cabbage over two growing seasons (November 2010-February 2011 and March-June 2011). Moreover, aphid dispersal between Siam weed and cabbage was investigated by conducting a caged experiment. From the field sampling of aphids and other arthropods, Aphis gossypii and Aphis spiraecola were both found on Siam weed, while A. gossypii was the only one species found in cabbage. Aphis gossypii was the most abundant aphid in both Siam weed (86.93, Siam weed sampling) and cabbage, and had highest population density during the dry season (October-March) which coincided with the growing season of cabbage and other Brassica in Nan Province. Camponotus rufoglaucus was the most abundant tended-ant (relative abundance=39.8%) with preference for honeydew and had the strongest relationship to A. gossypii while Odontoponera denticulata was the tended-ant with predatory role. However, the most important predator of aphids was spiders with strong negative relationship to the aphid population in Siam weed. Most aphids and other arthropods observed in the field experiment had similar diversity and rank abundance as the field sampling results, except Lipaphis erysimi which was the individuals m⁻²dominant aphid on cabbage instead of A. gossypii. The interaction of one aphid species, A. gossypii, and two tended-ants, C. rufoglaucus and O. denticulata, was conducted in a cage experiment to measure the population growth rate and dispersal rate of aphids, in Siam weed and cabbage. C. rufoglaucus treatment exhibited the positive effect on aphid abundance and aphid dispersal rate significantly while O. denticulata treatment exhibited the negative effect on aphid abundance and aphid dispersal rate confirming its predatory role on aphids and its ability to delay aphid population to reach carrying capacity. However, the nonsignificant difference of mean aphid abundance and dispersal rate between C. rufoglaucus treatment and non-ant treatment indicated that A. gossypii was the facultative myrmecophiles. In conclusion, this study confirmed the potential of Siam weed serving as aphid and beneficial arthropod reservoir as well as the different role of tended ants in the population growth and dispersal of aphids between weeds and crops. Therefore, consideration of both negative and positive effects in ecological roles of Siam weed and aphids were required in formulating the suitable management for Siam weed and aphids in agroecosystem.

title: Effects of propylene-ethylene copolymer on gravure printing of corona-treated BOPP film

description: In this study, the BOPP film samples were prepared using the 3-layers co-extruder, with 1.0 µm thickness of skin layer. The skin layer of BOPP film was modified by adding propylene-ethylene copolymer at various amount of 3-6% by weight. The film surface was subjected to corona treatment which was in line of production after the film was completely biaxially oriented. The contact angle of these BOPP films was subsequently measured and their surface free energy (SFE) was calculated. In addition, the effect of antistatic agent and slip agent in the major layer of BOPP film to SFE were also investigated. The results exhibited that the SFE of BOPP films was higher with the increasing content of propylene-ethylene copolymer and the presence of the antistatic agent. At 6% of propylene-ethylene copolymer in the skin layer, the SFE of BOPP film was approximately 20% higher than the original BOPP film. Its FTIR spectrum of BOPP film at 6% showed the carbonyl absorption band with highest intensity compare to the others. The printability of BOPP films was also investigated using Gravure proof machine with magenta and cyan inks. The printing images of BOPP films were visually observed with a microscope. It was found that exhibited the best printing image due to the least disappearance of the unit cell on the dot screen.

title: Rapid and highly sensitive analysis of ethoxyquin residues in shrimp using ultra performance liquid chromatography-tandem mass spectrometry

description: A rapid, sensitive method for quantitative and qualitative analysis was developed for the determination of ethoxyquin residues in shrimp. The method involved a new sample preparation process based on QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) methodology. Ethoxyquin was extracted from homogenized samples with optimized condition using 2% acetic acid in acetonitrile, followed by a cleanup step of dispersive solid-phase extraction using 50 mg of primary secondary amine and 10 mg of graphitized carbon black and then dilution of an extract with acetonitrile: water (80:20). The detection of ethoxyquin was achieved by ultra performance liquid chromatography–tandem mass spectrometry within 2 min retention using positive electrospray ionization mode. The validation method has been performed according to guideline of pesticide residues analysis in food and feed NO.SANCO/10684/2009. Good performance data were obtained with recovery of ethoxyquin from the spiked shrimp samples at 1.5–50.0 µg/kg equal to 82-92% and relative standard deviations were in acceptable range (&lt;6.2%) when compared with the value from Horwitz equation. Good linear calibration in the range of 0.8–64 µg/kg was yielded with coefficient of determination above 0.995. The limit of detection was 0.45 µg/kg. The optimized method has been successfully applied to real shrimp sample which can be detected ethoxyquin in a range of 1.5-350 µg/kg from local fresh markets and super markets, Bangkok, Thailand and the shrimp farm for export in Thailand. The method can also be employed for shrimp analysis in routine laboratory with high sample throughput.

title: Population pharmacokinetics of nevirapine in HIV-infected patients

description: Background Nevirapine plasma concentration has been shown to be associated with virological response, treatment failure and adverse drug reactions. Nevirapine has a high interindividual variability, therefore identifying sources of the variability of nevirapine pharmacokinetics is important for dose optimization. Objectives To develop a population pharmacokinetic model of nevirapine, to determine population mean pharmacokinetic parameters, and to identify factors influencing the pharmacokinetic parameters of nevirapine in HIV-infected patients. Methods A retrospective descriptive study in 236 patients, data were extractedfrom clinical studies from The HIV Netherlands Australia Thailand Research Collaboration (HIV-NAT) and Bamrasnaradura Infectious Disease Institute. The model was developed by a nonlinear mixed-effects modeling approach using NONMEM®. Model validation was performed using Bayesian estimation. Results A one-compartment model with first-order absorption and elimination found to be the best model for describing nevirapine pharmacokinetics. Age more than 40 years and aspartate aminotransferase (AST) level more than 60 U/L decreased nevirapine apparent oral clearance (CL/F) by 18% and 16%, respectively. The concomitant use of rifampicin increased nevirapine CL/F by 22%. The results from model validation showed that the mean prediction error of the final model was -0.10 mg/L and was not significantly different from zero (p=0.49). The Bland-Altman plot showed no systematic bias. Conclusions The nevirapine CL/F in this population was slightly lower than previously reported in other populations. The patient characteristics which influence nevirapine CL/F were age as categorical variable (≤40 years, &gt;40 years), AST level as categorical variable (≤60 U/L, &gt;60 U/L) and rifampicin use. The model obtained from this study can be used for nevirapine dosage optimization for individual patient.

title: Iterative error re-establishment to improve neural network cost function for imbalanced data learning

description: A new training algorithm to enhance the accuracy of minority class in imbalanced data learning problem was proposed. This algorithm is based on the observation that the cause of lower accuracy is due to the domination of the error terms, i.e. the square of difference between the target and the actual output, computed by those data in majority class in the cost function. To resolve this domination, our cost function is re-established at each epoch based on the errors of the data in minority and majority classes. Any datum whose corresponding term in the cost function produces an error less than 0.05 is removed from cost function. Otherwise, it is put back into the cost function. Our algorithm adopting multilayer perceptron and Levenberg-Marquardt (LM) as the learning algorithm was compared with classical LM and the recent algorithm RAMOBoost on 15 well-known benchmarks. The experimental results of our approach produced higher accuracy than the other approaches in 13 cases with faster training speed.

title: Application of airbone geophysical and reomote sensing data to the interpretation of geologic setting in Nan-Uttaradit area, Northern Thailand

description: This investigation is aimed to reprocess airborne geophysical and remote sensing data for interpreting subsurface structures in the Nan-Uttaradit area. Airborne magnetic data in conjunction with remote sensing and EM data have been enhanced using various techniques. This study applies that RTP, ANA, AGC, vertical derivative, upward and downward continuation, for interpretation. Airborne radiometric data processed by Cooking Technique and Remote sensing data by Band Combination and Principle Component Analysis Technique. Three domains have been identified, namely northern, central and southern domain. The central domain is a significant highly anomalous NE-SW trending narrow zone situating within the Nan River Basin. This domain possesses high magnetic and low radiometric intensities. The central high magnetic domain is enveloped by very low magnetic and high radiometric intensities referred as the north and south domains, both of which orient in the N-S direction and they generally exhibit the low magnetic and various radiometric intensities with the sporadic high magnetic patterns. The northern domain is quite different from the southern domain, suggesting contrast in the geology. The high magnetic anomalies in each domain have been recognized in 2 patterns, elongate pattern located mainly along the Nan River in the NE-SW direction with high magnetic and low radiometric intensities, and circular pattern located in the northernmost area with low magnetic anomalies zone in southern part area. After using magnetic modeling program to identify polarity of magnetic bodies, their patterns show the well-defined east-dipping direction. After validation with previous petrochemical and field investigations, it is quite reliable that the Nan suture formed in island-arc system, not by the continental collision setting as previously thought. The occurrence of island arc-type mafic/ultramafic rocks and their associated chromian spinels suggest an eastward ocean-ocean subduction that is consistent with the present geophysical model. Therefore, it is ascertained that the Nan suture zone can be well delineated and definitely extends northeastward to the Lao PDR.

title: Development and implementation of an interactive muti-modality (IMM) for self-management support among patients with type 2 diabetes in Bangkok, Thailand

description: The purpose of this study was to develop the interactive muti-mutimodalities technology (IMM) including website, email, and SMS for self-management support and to evaluate the effects of IMM among patients with diabetes type 2 who lived in Bangkok after 3-month overtime. The 4 settings with 124 participants were subsequently allocated to the intervention group (n=74) and the control group (n=48). The IMM on the website consists of 4 main functions that were self-regulation, self-monitoring and assessment, social support, and reminder system-linked to email, SMS. After 3 months, the participants declined in both groups to 55 and 30 respectively. T-test, Chi-square test, and Multiple regression with correlation were used to examine means of HbAlc level and behavioral scores including diabetes quality of life (QoL), self-efficacy, and self-management. The findings revealed that were a significant difference in HbA1c between the intervention and the control group (p 0.001). HbA1c level decreased in the intervention group but it increased in the control group significantly (p &lt; 0.01). Self-care score increased significantly between groups (p &lt; 0.05 ) and within the intervention group (p &lt; 0.001). The increasing self-efficacy score associated with decreasing HbAlc (p &lt; 0.05). A further study will expand to a large population and deliver the technology to diabetes clinic. However, the IMM should be improved to be fully functionality. Importantly, the providing health professional should plan for the exclusive further system.

title: Degenerate primer designing system for gene biodiversity study using dynamic pattern matching

description: Degenerate primer design for studying biodiversity is a difficult step in molecular biology. The primers must be specific to the gene. Choosing the right primers are somewhat difficult and sometimes led to mismatching. Several primer design systems have been developed to overcome this problem. In this study, the Dynamic Pattern Matching technique has been developed and applied to find bacterial universal primers and specific primers for Glycoside Hydrolase Family 45 genes. Aligned sequences from test sets are entered into the system which consists of three steps: data reformation, primer design, and property filtering. First, degenerate and consensus sequences are calculated using statistical models. The results are combined with Gibbs Free Energy to design and select the most appropriate sequences as a series of primer sets. Moreover, users can also adjust their own criteria for each primer set. The results indicate that the degenerate primers designed by our proposed system are proved to be positive.

title: Diversity and succession of carrion arthropods on pig sus scrofa domestica carcasses under different conditions in Nan province, Thailand

description: This research aimed to establish the basic preliminary data base of insect species associated with decomposing cadavers and the main succession trends to develop forensic entomology in Thailand. Insect succession and rate of decomposition were studied on domestic pig (20-25 kg) carcasses during 2010-2011, in Nan province, Thailand. Three major differences were considered, the affect of habitat (mixed deciduous forest and rural area), season (monsoon wet, winter and summer seasons) and spatial position / access (carcasses were hung on a tree or laid on the ground). The ambient temperature and relative humidity in the vicinity of the carcass, the internal carcass temperature and the rate of carcass decomposition were compared with the insect succession stages for each experimental variable. Habitats, seasons and spatial positions of the carcasses directly affect the decomposition rate of the carcasses, being greater in ground-laid carcasses than hanging carcass in the wet and winter seasons. Patterns of insect succession occurred in a predictable sequence that varied across the different habitats, seasons and conditions. About 40 taxa were collected and identified. Chrysomya megacephala and Achoetandrus rufifacies were the dominant fly species in every season. The diversity of carrion insect was highest in monsoon wet season, followed by summer and winter seasons, respectively.

title: A business strategy for construction materials modern trade : case of small-to-medium sized company

description: The main purpose of this research is to formulate a business strategy for small-to-medium sized construction materials modern trade that operates in a competitive situation. The research is conducted by performing internal and external analysis to gain an understanding of the current market situation. For internal analysis, this research uses data from customer questionnaire survey and interviewing the company’s managing people. For external analysis, Porter’s five competitive forces framework and PESTEL analysis are utilized. The company’s SWOT and key success factors then can be derived from the information in order to form the marketing concept. The marketing strategy is then formulated from the concept, consisting of business model for the strategic dimension and action plan for the operative dimension. Situation analysis found that despite its being complimented of good product and service, the case study modern trade is unable to compete in the construction material price war. However, since its own line of all wood furniture production has no competition and sells well and its competitors offer narrower scope of design jobs, the strategic solution has been reached. The business decides to differentiate itself by focusing instead on providing furniture products and design works. The business model is then constructed based on the new value propositions of lifestyle, good product and service quality and customer co-creation/customization. The validation of the n model exercises the comparison between the old and the new model. The business model framework, selected as most appropriate, provides the framework of nine elements as aspects to be necessarily considered for a business model. By putting the old model into the same framework, it is found that the old framework has inconsistencies of value propositions against some of the key elements. This is due to the company failing to see the clear picture of the business, which results in unsystematic model as opposed to the new systematic one.
