title: Fabrication of cobalt-iron thin film for magnetic recording head core by electrodeposition and heat treatment

description: According to the dominant soft magnetic properties of CoFe alloy, it has a high potential as soft magnetic films for applications in electrical and electronics industries, especially the writing head core of hard disk drive. However, the knowledge and systematic study to improve the soft magnetic properties of such materials is limited. This research investigates the factors associated with soft magnetic properties of the material produced by electrodeposition and post annealing techniques. The factors of the fabrication include chemical composition, thickness, annealing temperature. These factors are considered with the film's structural elements, namely grain size, roughness, crystallographic orientation, magnetic domain, stress and the applied magnetic field both at room and low temperature. The research is divided into three parts. In Part I, the effects of the chemical composition on the thickness of the electrodeposited CoFe films were studied. It was found that high thickness improves the homogeneity and suppresses defects in the films providing good soft magnetic properties. When the Fe content is low, the texture coefficient at plane (110) and the saturation magnetization is high. Moreover, the grain size is the factor controlling the coercivity of the film. The film with low coercivity contains 'bubble-liked' domain pattern. In Part II, the effect of the stress on the annealed CoFe films were considered. It is found that annealing reduces stress but does not decrease the coercivity due to the increase in uniaxial anisotropy constant. The saturation magnetization varies directly with the texture coefficient of (110) plane. In Part III, the effects of applied magnetic field both at room and low temperature were observed. The in-plane direction of the uniaxial anisotropy reduces the coercivity and varies directly with the grain size while the saturation magnetization depends on the uniaxial anisotropy. Furthermore, the low temperature increases the uniaxial anisotropy constant and the magnetic induction saturation.

title: Development of the TiO2-coated Silk Fibroin Filters for Treatment of Gaseous Formaldehyde in Indoor Air

description: This research focuses on synthesis of TiO2-coated silk fibroin (SF) filters and their application for treatment of indoor air contaminant via photocatalytic oxidation process (PCO). Formaldehyde (HCHO), one of major indoor air contaminants, was selected in this study. This work can be divided into 4 phases including: phase 1 monitoring of HCHO concentrations in a gross anatomy laboratory (GAL) and general health survey, phase 2 synthesis of SF filters and study of morphological structure and physical properties, phase 3 treatment of HCHO in a small reactor using the synthesized SF filters and commercial filter, and phase 4 application of the TiO2-coated SF filters for PCO of HCHO in a large modeling room. For the first phase, the highest HCHO concentration observed was 15.66 ± 0.00 ppm. The result of general health survey showed that the most medical symptom occurred was irregular heartbeat. For the second phase, TiO2-coated SF filters were synthesized and analyzed for morphological structure by Scanning electron microscopy (SEM), UV–VIS spectrophotometer, Fourier transform infra-red spectroscopy (FT-IR), Thermogravimetric analysis (TGA), isotherm of adsorption and desorption of nitrogen gas on the SF filter, and physical properties by tensile strength method. The SEM images revealed that the TiO2 was relatively well scattered on SF surface. The band gap energy was 3.18 eV. The removal efficiency of HCHO in a small reactor with 40x45x50 cm3 was conducted for impact of initial HCHO concentration, catalyst (TiO2) dosage, and air flow rate. From the studies, the highest removal efficiency of approximately 68.23 ± 0.44 % was obtained at initial concentration of 5.0 ppm, catalysis dosage of 5.0 % (TiO2 wt /vol.sol.), and air flow rate of 5 L/min. Moreover, the results derived from the kinetic model revealed that the photocatalytic rate follows the first order reaction. The simplified L-H reaction rate constant was calculated to be 0.0061 min-1. For application of the TiO2-coated SF filters for treatment of HCHO in a large modeling room of 1.2x1.2x1.85 m3 at air flow rate of 84.40 ft3/min, it was found that the removal efficiency of HCHO was approximately 54.72 ± 1.75 %.

title: DEVELOPMENT OF AN ENGLISH INSTRUCTIONAL MANAGEMENT MODEL BASED ON DIFFERENTIATED INSTRUCTION AND UNIVERSAL DESIGN TO ENHANCE ENGLISH LEARNING ACHIEVEMENT, SOCIAL SKILLS, AND LEARNING ENGAGEMENT OF UNDERGRADUATE STUDENTS WITH AND WITHOUT HEARING IMPAIRMENT IN INCLUSIVE ENGLISH CLASSROOMS

description: The objectives of this study were to develop an English instructional management model based on differentiated instruction and universal design for learning to enhance English learning achievement, social skills, and learning engagement of undergraduate students with and without hearing impairment in inclusive English classrooms. The research processes consisted of four phases: situation analysis, model development, model implementation, and model evaluation. The model was developed based on the results of the situation analysis and related literature and implemented in a foundation English classroom for undergraduate students. Fifty hearing students and four students with hearing impairment participated in the study. English learning achievement tests, social skill questionnaire, learning engagement questionnaire, learning logs, and semi-structured interviews were employed to evaluate the effects of the model. The results of the study was an English instructional management model for English inclusive classrooms with students with and without hearing impairment entitled “The DI&UD English instructional management model.” The model describes the types of accommodation and adaptation in four teaching steps of an English lesson—lesson introduction, language input, language task, and conclusion. Regarding accommodation, students with hearing impairment were supported by a sign language interpreter and a note-taker. For adaptation, content, process, and product were differentiated to provide equal opportunities for both groups of students to access instructional materials, activities, and assessment tasks in inclusive classrooms. The results of the model evaluation indicated that the DI&UD English instructional management model had positive effects on students’ English learning achievement, social skills, and learning engagement; however the effects on the students with and without hearing impairment differed in regard to English learning achievement and learning engagement. These results suggest that the DI&UD English instructional management model can be used in English inclusive classrooms to support students with hearing impairment with some adjustment in order to enhance all four communication skills and learning engagement. Since the DI&UD English instructional management model includes the provision of many types of accommodation and adaptation which may not always be available in natural classroom settings, further research can be conducted to investigate the most effective types of accommodation and adaptation in the model so that English educators will be able to design the instruction that is appropriate to their local contexts and resources.

title: INCREASING FINANCIAL HEALTH STABILITY FOR LOGISTICS COMPANIES IN THAILAND

description: The objectives of this paper are: 1) to identify the factors that determine long-term financial stability, and 2) to develop a model of long-term financial health for logistics companies in Thailand. While many studies have referred to financial ratios as factors affecting financial health, only a few non-financial ratios such as age and size have been mentioned. This paper considers both the financial and non-financial ratios that affect the financial performance of logistics companies in Thailand. The study has covered some interesting non-financial ratios such as the nationality of shareholders, type of networking, growth rate (consisting of sales growth rate/profit growth rate/asset growth rate/liability growth rate) and the variable of growth rates. The sample consists of 110 logistics companies in Thailand enlisted from the Department of International Trade Promotion Ministry of Commerce. Multiple discriminant analysis (MDA) was used as the research instrument. MDA by SPSS was applied to analyze the 5-year data from 2009-2013. Multimonial logistic regression analysis (MLRA) was another tool applied after getting the significant variables from MDA. There are two cases in the study consisting of Case 1 that applied all variables at the same time, and Case 2 applied financial variables and non-financial variables separately. The results that show the five major robust factors that impact financial health are RETA, BVETL, Size, Nationality of Shareholders and No. of Shareholders, while the minor factors are CFD, Age and Type of Network.The output of this research together with the appropriate model could be used to increase the financial health of logistics companies in Thailand.

title: POTENTIAL UTILIZATION OF COFFEE GROUND MATERIAL AS CADMIUM AND ZINC STABILIZING AMENDMENTS : A CASE STUDY OF MAE TAO, TAK, THAILAND

description: The present research studied the potential utilization of untreated coffee ground (UCG) and carbonized coffee ground (CCG) as Cd and Zn stabilizing amendments in Cd contaminated soil collected from Mae Sot, Tak. Soil was determined with the average Cd and Zn concentrations of 47.2 and 1,660 mg kg-1, respectively. After preparation, UCG and CCG was separately mixed into the contaminated soil with the mixing ratio of 2.5%, 5%, 10% and 20% (w/w). All amended soils were incubated for a total of eight weeks. At the end of incubation period, BCR sequential extraction, DTPA extraction, and plant toxicity test were conducted in order to assess the mobility, plant availability, and toxicity of Cd and Zn in amended soils. The results revealed that the addition of UCG and CCG to contaminated soil resulted in the increase in soil nutrients and OM concentrations. In terms of Cd and Zn distribution, the exchangeable and reducible Cd were found to be decreased with the increasing mixing ratio of UCG. Similar results of Cd and Zn fractionations were observed in all mixing ratio of both UCG and CCG amended soils. In addition, the major Cd fractions during the whole aging process were exchangeable and reducible fractions. Whereas, Zn were mainly found in the forms of reducible and oxidizable fractions. In term of plant availability, Cd was found to be decreased by an average of 1.98% and 2.80% in UCG and CCG amended soil, respectively. At the same time, an increase in Zn plant availability was found in both types of amended soils. The results of phytotoxicity on rice germination, an increase in CCG mixing ratio could improve the possibilities of seed germination as well as root growth. The overall findings indicated that CCG can be considered as Cd immobilizing amendment to the contaminated soil.

title: Municipal solid waste metabolism in Bangkok

description: The main objective of this research is to identify low carbon municipal solid waste management (MSWM) schemes and policy recommendations for Bangkok. The study analyzed Bangkok’s municipal solid waste metabolism using Material Flow Analysis (MFA) and Geographic Information System (GIS). MFA of Bangkok’s MSWM indicated that landfill is the GHG hot spot. Landfills are the largest GHG emission source (88%) in Bangkok’s waste metabolism. Waste collection system is the energy consumption hot spot (82%). In addition, GIS displayed based on MSWM parameters (MSWc volume, net and intensity of GHG emission and energy consumption) revealed hot spot areas of each parameter. Among 50 districts, Pathumwan and Wattana districts are the highest hot spot areas in term of MSWc volume, net, and intensity of GHG emission. Analyses of Bangkok’s MSW metabolism provides insights for key factors and potential improvement to help developing a low carbon MSWM system. The study examined eleven scenarios to improve the performance of current Bangkok’s MSW metabolism. An approach on reducing 25% waste generation at sources has the highest potential to reduce GHG emission by approximately 24.5% and energy consumption by 24.21%. Multiple actions, comprising of (1) decentralized composting facility, (2) changing fuel type in the vehicles for waste collection, and (3) campaign for reducing 25% waste generation, showed the highest potential in GHG reduction (30.01%). The scheme that can yield the highest reduction of energy consumption approximates 36.58% is multiple actions comprising of (1) changing fuel type in the vehicles for waste collection, and (2) campaign for reducing 25% waste generation. Changing fuel types in waste collection truck and waste reduction campaign are practical options to promote a low carbon scheme in Bangkok which can help reducing GHG emission (0.29 MtCO2e) by 2020. The research developed a program that can help estimate emission of MSWM in local districts. Recommended options/policies of MSWM present with potential GHG reduction as the output of the developed program. The program can help provide informaiton for decision making at a district or provincial level toward low carbon waste management.
