title: Mangrove mud metagenome : the source of new gene involving in bioactive compound biosynthesis and microcial diversity access

description: In this study, the polyketide synthases (PKS) genes involving in biosynthesis of polyketides, the groups of prolific and various structural and functional bioactive compounds were searched on metagenome of soil microbial community from Klongkone mangrove forest, Samut Songkhram Province, Thailand. Detection of ketosynthase (KS) domain gene of type I polyketide synthase (PKS) in the mangrove mud metagenome by polymerase chain reaction (PCR) using degenerate primers specific for the conserved motif VDPQQR and the histidine active site motif HGTGT resulted in 12 diverse KS domain genes. Deduced amino acid sequences of these novel domains were 34-70% homology. Most of the discovered KSs were phylogenetically related to cis-AT type I PKS, one was related to trans-AT and the others were related to NRPS preceding hybrid PKS/NRPS, which groups of hybrid PKS/NRPS I-II and III were newly proposed in this study. A variety of novel 16S rRNA gene phylotypes were also found by analysis of PCR-product clones. They were phylogenetically related to bacteria in phyla Proteobacteria, Acidobacteria, Deferribacteres, Chloroflexi, Verrucomicrobia, and Lentisphaerae. One phylotype was related to unclassified bacteria. In searching for PKS gene in the mangrove soil metagenomic library constructed with fosmid vector, novel PKS and NRPS modules were found in clone KKFOS_KSI_pool37_088 with the 29 kb DNA insert. These revealed that Klongkone mangrove soil harbored various novel diverse PKS genes and bacteria which could be accessed through metagenomics.

title: High efficiency separation in capillary electrochromatography and capillary liquid chromatography using monolithic stationary phase

description: C18 monolithic silica capillary columns modified with octadecyl moieties (ODS) and poly(octadecyl methacrylate) (ODM) were prepared for reversed-phase capillary liquid chromatography (CLC). A high column performance was obtained with plate height (H) nearly or less than 10 m and permeability in a range of 7.3×10-14-9.4×10-14 m2. In comparison of ODM and ODS stationary phase selectivities for halogenated compounds, such as halogenated benzenes and chlorophenols, the ODM columns have greater preference and greater selectivity for these compounds due to the greater dispersive interaction by more densely packed C18 groups on ODM polymer coated column together with the contribution of carbonyl groups in ODM side chain. In addition, the reversed-phase ODS and mixed-mode ODS/AP1 or ODS/AP2 monolithic silica capillary columns were prepared for capillary electrochromatography (CEC) with H in the range of 3.7-4.0 µm, where AP1 and AP2 refer to aminopropyl and 3-(2-aminoethylamino)propyl moieties, respectively. These mixed-mode columns have the preference for phenolic compounds. Moreover, the separation selectivity was compared in capillary electrophoresis with different modes. Capillary zone electrophoresis with the addition of cyclodextrin (CD-CZE) showed the better separation selectivity for chloro- and methylbenzoates than CZE without cyclodextrin and micellar electrokinetic chromatography. The separation selectivity patterns were also developed for the separation of fully charged achiral compounds using a neutral cyclodextrin.

title: Assessing probabilities of default in Thai corporate bond market

description: This study employs the structural models i.e. Merton, Black and Cox, Longstaff and Schwartz, and reduced-form models, i.e. Jarrow and Turnbull; Constant Hazard Function model, Linear Hazard Function model and Quadratic Hazard Function model to assess the probabilities of default in the Thai corporate bond market. The study covers corporate bonds listed on Thai Bond Market Association (ThaiBMA) and Stock Exchange of Thailand (SET) from January 2001 to June 2006. We then compare the accuracy of default probabilities of each model by using probabilities of default to predict corporate bond price in next 1-month and 3-months. Thus, calculate the value of Mean Absolute Percentage Error (MAPE). Of all the result comparing probability of default value from six models, the average probabilities of default from structural form is lower than from reduced-form in Merton Model which gives the lowest value. For average probabilities of default from reduced-form models: Quadratic Hazard Function model has highest range of all. Comparing MAPE, forecast price in the next 1- month shows that MAPE from reduced-form: Quadratic Hazard Function model gives lowest value followed by MAPE from reduced-form: Linear Hazard Function model, reduced-form: Constant Hazard Function Model, Merton model, The Black and Cox model. For MAPE from Longstaff and Schwartz model has highest value. In MAPE in order to forecast price in the next 3-months, the results correspond with the forecasted price in the next 1-month. Since the mean of MAPE obtained from reduced-form model has lower value than the mean of MAPE obtained from structural form model for all firms. This infers that the probability of default from the reduced-form model is more effective in predicting the bond price than calculated from the structural model

title: Improvement of inventory control system

description: This thesis attempts to look at the inventory management practices of a relatively new company that has shown progress in its operations. The business of the case company is trading. The main job involves analyzing relevant historical documents over the 10 months from May 2007 to February 2008 to cover the fluctuation of demand. The company’s products are divided into 3 categories to facilitate analysis, and eventually to select only the most important category for detailed study. The imported products with known price increases turned out to have the most value and were of the most importance to the company. The Known Price Increase Model was then modified and applied to these products to serve as the basis for considering the stocks that had to be ordered for storage in order to optimize return on investment. The conventional Fixed Order Quantity Model was used for the products the prices of which do not change frequently. As the case company has 2 warehouses that are situated apart, and have limited storage capacity, it was studied the ratio of the products for storage at the 2 warehouses to increase efficiency and better management control. When an attempt to determine the quantities of all the products under study that have to be ordered and stocked in the inventory was carried out, it was discovered that the company did not have sufficient storage capacity for all of them, namely, the storage capacity needed was 8,421.88 cubic meters but the storage capacity available in warehouse A is only 1,750 cubic meters. This shortfall is not unusual, especially since this company is quite new and could reasonably be expected to be cautious in its operations. The study shows that the total savings from using the Fixed Order Quantity Model for all the unclassified products is 44,594.93 baht, or equal to 7.89 per cent of the Total Stocking Cost (TSC). The savings from applying the Known Price Increase Model to imported products and domestic products with known price increases products is 594,512.30 baht

title: Cost analysis of "Samadigama" Primary Health Care Unit in Sri Lanka

description: To analyze total cost and unit cost of Central Dispensary “Samadigama” in provider’s perspective. CD “Samadigama” is an integration model of providing curative and preventive care services through one center at the primary level facility. This model is currently established in 2007 and implementing at southern part of Sri Lanka, namely Hambantota district, which is based on Classical Primary Care Concept in Taiwan. We use the step-down technique to calculate the unit cost of each patient service department. The data in year 2008 are collected using secondary sources and observation method. We find that the unit costs are Rs.147.00 for OPD, Rs. 261.00 for medical clinic, Rs. 514.00 for antenatal clinic, Rs. 940.00 for well baby clinic, Rs. 561.00 for family planning clinic, Rs. 418.00 for dental clinic and Rs. 232.00 for ayurvedic clinic. The unit costs are relatively high due to lack of full-time staff and underutilization of services. Therefore, we suggest extending number of full-time staff and number of service hours the results show that the unit costs will be reduced by 35% of OPD, 75% of medical clinic and 9% of dental clinic as so on.

title: Cost and effectiveness of screening methods for abnormal fasting plasma glugose and undiagnosed Type 2 diabetes

description: Cost-effectiveness in whether or not screening for undiagnosed type 2 diabetes in asymptomatic individuals is unknown, and policy statements on this topic are controversial. In Thailand, type 2 diabetes was implementing at national level by the Ministry of Public Health (MOPH) recommendation but screening methods have not been fully evaluated. Thus, the aims were to compare the performance, cost, and cost-effectiveness of four screening methods in identifying individuals with abnormal fasting plasma glucose and type 2 diabetes. This study was conducted among people ages 35 - 60 years old with no known type 2 diabetes and pre-diabetes (2,977 people). All subjects completed a set of screening questionnaires and followed by fasting plasma glucose (FPG) testing for those with positive result. Universal FPG testing was conducted and used as the reference for all other screening methods to compare with. One-time screening performance and costs were analyzed from both single-payer and societal perspectives. The results show that sensitivities of all screening methods were high to very high (71-92% and 65-97% respectively for abnormal fasting plasma glucose and type 2 diabetes), while the specificities were low to moderate (31-57% and 29-54% respectively for the screening of both conditions). The total cost of the most effective screening method (which was proposed by Aekplakorn et al) for abnormal fasting plasma glucose and type 2 diabetes were 165,766 and 166,477 bahts respectively. Their corresponding cost-effectiveness was 2,047 to 2,381 and 18,497 to 23,179 bahts per newly detected case from societal perspective, and 933 to 1,185 and 8,309 to 11,876 baht per newly detected case from a single-payer perspective. Thus, screening method proposed by Aekplakorn et al was the most effective and highest cost-effectiveness to identify newly detected abnormal fasting plasma glucose and type 2 diabetes cases among Thai adults

title: Developmet of sterilized mixed herbal drink product

description: This research aimed to develop sterilized mixed herbal drink product formula and processes from Imperata cylindrical (L.) P. Beauv. [IM], Murdannia loriformia (Hassk.) Rolla Rao et Kammathy [ML], Hedyotis corymbosa Lamk. [HC], and Orthosiphon aristatus Miq [OA]. The chemical composition and potassium content of the herbs were analyzed. The appropriate extraction condition using herb: water ratio of 1: 49, and extracting at 70 ℃ , 80℃ and 90 ℃ for 30, 45 and 60 minutes were investigated. The formula of mixed herbal drink was developed to determine the proportion of each herbal infusion and sugar level. The most acceptable formula of mixed herbal drink was then sterilized at 130℃, 135 ℃ and 140 ℃ to obtain F[subscript 0] of 3, 4 and 5 minutes and filled in PET bottle then all samples were investigated. The sterilized mixed herbal drink was kept at 30℃ for 4 months and at 45 ℃ and 55℃ for 2 months. Changes in the physical, chemical, microbiological properties and panelists’ preference of the samples were determined every week during storage. From the study, all herbs had high amount of fiber (24.11-60.45%) and low amount of protein (1.16-10.96%) and fat (0.46-10.12%). ML and OA had the high amount of potassium (2.01% and 1.35%). Increasing extraction temperature and time caused darker product, reduction in antioxidant activity and ascorbic acid but increasing in total phenolic compounds and potassium. From response surface methodology, the most appropriate extraction condition was 74.6 ℃ for 41 minutes. The most acceptable formula contains 14% IC infusion, 35% ML infusion, 27% HC infusion, 17% OA, and 7% sugar. Increase F[subscript 0] in sterilization step resulted in darker product and reduction in antioxidant activity and total phenolic compounds, but did not affect pH, total soluble solid, and potassium. Moreover, no microorganism was detected in all samples. The most appropriate sterilization process was 135.4℃ with F[subscript 0] = 3 minutes. Increasing storage time and temperature caused a decrease in antioxidant activity and total phenolic compounds and increase in panelists’ preference. Total phenolic compoundswere predicted to deplete absolutely in the week 27[superscript th]at 30 ℃

title: Nitrogen Input, Nitrogen Surplus, and Nitrogen Use Efficiency Globally and for Selected Regions

description: Data on nitrogen input, surplus and nitrogen use efficiency are provided globally, and for USA, European Union, China, Brazil and South Asia (i.e. India, Nepal, Bangladesh and Pakistan) for 1995 to 2013. Nitrogen input (in the file ninput_1995_2013.csv) is separated into synthetic fertiliser (FERT), manure (MANURE), biological nitrogen fixation (BNF), and NOx deposition from non-agricultural sources (NOx). These N-inputs are for the whole agricultural system, including crops and grassland. Also included is N-surplus (SURPLUS) for cropping systems, which is calculated as the difference between the total N-input and the N removed through harvest. NUE (in the file nue_1995_2013.csv) is N in harvest relative to the total N-input. Synthetic fertilizer application is based on the FAOSTAT dataset (http://www.fao.org/home/en/) with several inputs from the International Fertilizer Association (https://www.fertilizer.org/). Total animal excretion is calculated using the FAOSTAT livestock inventory and dynamic excretion factors, biological N fixation is calculated from crop productivities (Anglade et al., 2015)<sup> </sup>and atmospheric deposition was from Dentener et al. (2006). Grassland nitrogen fixation was based on the grassland production estimated following Lassaletta et al. (2016). N in harvested crops is based on crop productivity and N content of 177 crops, utilizing data from the FAOSTAT database.

title: Catalytic cracking of butane on modified ZSM-5 catalyst

description: Light olefins synthesis from butane was investigated on H-ZSM-5 modified with phosphorus or magnesium. The effect of introduction of phosphorus or magnesium was also studied using incipient wetness impregnation and solid state ion exchange. H-ZSM-5 with Si/Al ratios of 40, 70 and 100 were hydro thermally synthesized, and the catalytic performances were examined during 400 – 700℃. The H-ZSM-5 with Si/Al ratio of 70 exhibited the relatively high light olefins yield at 600 ℃. Further modification of the catalyst was made by introduction P or Mg ranging from 0.1 – 3.0 % by weight via incipient wetness impregnation and solid state ion exchange. The introduction method gave significantly indifferent yield of light olefins for each of P and/or Mg. However, H-ZSM-5 modified with P exhibited relatively higher light olefins yield than did Mg. The better dispersion of P-modified ZSM-5 observed from SEM images should be responsible for the good catalytic performance. On the other hand, the adverse effect of Mg may be attributed to the pore blockage as clearly demonstrated by SEM and micro pore results.

title: The efficacy of oral aloe vera juice for radiation induced mucositis in head and neck cancer patients : a double-blind placebo-controlled study

description: Objective: To evaluate the efficacy of oral aloe vera juice in the alleviation of radiation induced mucositis in head and neck cancer patients. Study design: Double-blind randomized, placebo-controlled study. Setting : Radiotherapy and Oncology unit, Ramathibodi Hospital. Research Methodology: 61 eligible head and neck cancer patients who received conventional radiation therapy were randomized to received oral aloe vera juice(N=30) or placebo (N=31). Mucosal reaction was assessed during the course of radiation using RTOG grading system. Results: Patient baseline characteristics were identical in both arm except gender, which was more male patient in the aloe vera group (p=0.03) and previous surgery, which was higher in the placebo group (p=0.04). The incidence of the severe mucositis was statistically significant lower in the aloe vera group compared with the placebo (53% vs 87%, p =0.004). However, there was no statistically significant difference in the onset of severe mucositis. No adverse effects related to the drug were reported in this study. Conclusions: Oral aloe vera juice had some benefits in alleviating the severity of radiation-induced mucositis without any side effects. Because it is easy accessible in Thailand with a relatively low cost, the aloe vera juice should be considered as a good alternative agent for the radiation-induced mucositis in patients with head and neck cancers
