title: Effects of infrastructure on storm drainage system and flood protection in hillside coastal plain : case study of Hua-Hin municipality, Prachuabkirikhun province

description: Flood problem is a chronic problem, which frequently occurs in Hua – Hin Municipality, where is the most famous of seaside tourism of Thailand. Flood problem directly affects the socio – economic and transportation system of this area and it trend to increase the severity if there is no plan to intentionally solve the problem. The main objectives of this research are study of the causes of flood problem, and determine the adequacy of drainage system of the city. The methodology was divided into 2 parts; 1) open - channel or waterway system, and 2) pipe system in downtown. According to the research, there are 10 existing natural canals in this area. In the first part, the total canals were analyzed the efficiency by calculating each canal individually. Then the results were compared to the existing condition of canals. The outcomes of the field survey indicate that all of canals were obstructed by the most of infrastructure of the city which include; 1) irrigation canal, 2) railway, and 3) highway No.4 (Petchkasem Road). The most of intersections - between canals and infrastructures are hydraulic structures which are channel, tunnel, or culvert etc. These hydraulic structures changed the cross – section of canal which was the result of decreasing the efficiency of drainage system extremely. In the conclusion, the effects of infrastructure could be separated into 2 main categories; 1) the effects of open channel or waterway system that there are the obstruction of channel of irrigation canal, the tunnel of railway, and Highway No.4 that are culverts. These infrastructures are the neck bottle of open - channel so that it cannot instantly drain runoff when it was in flood condition. And 2) The expansion of Highway No.4 - between the section 207+600 km to 235+800 to be 6 lanes road from the original 2 lanes road - affects directly to the length of culverts, so, runoff cannot be drained immediately when there is a heavy rainfall or flood condition

title: The shan people's consumption of Thai 'Chak Chak Wong Wong' television serials

description: The goal of this research is to investigate the cross border consumption of Thai chak chak wong wong television serials (CCWW) by focusing on a case study in Myanmar’s Shan State. The study covers the beginnings of Thai CCWW television serials in the Shan State, dubbing operations, consumption networks, and the Shan people’s translation of CCWW into local languages. It applies the ethnographic research methods, especially the participant observation and in-depth interviews with focus groups, namely the Samphinong dubbing company in Taunggyi, the capital city of southern Shan State, as well as five distributors from Shan townships. Measurements of the CCWW consumption and its network were based on Samphinong’s accounting books for 2008. The research discovers that the cross border consumption of Thai CCWW began when the Myanmar government opened up its economic policies, which led to the introduction of new technology and media to the Shan State for community’s entertainment. As a result, the CCWW serials, mostly Buddhist drama, became popular. After the government cracked down on the foreign media, only the Samphinong group survived to dub CCWW, as well as the evening serials. New technologies, especially the satellite dish which provides television signals directly from Thailand, have changed the consumption, as well as the CCWW trade. VCDs have also become convenient media for distant consumers. The dubbing studio in Taungyi, however, faces certain risks under Myanmar’s strict media laws. Based on well-known Jataka tales, CCWW as religious dramas have minimized such problems. Negotiations have occurred with local authorities and partnerships have been formed as well. To localize CCWW for the Shan people, translations are necessary for local audience’s comprehension, for example, titles and actor’s names are changed accordingly to the Shan’s worldview, which is rather different from the original source. The Thai and Shan are widely connected by their shared cultures and religions, but in the context of modernization, the Tai worlds are diverse, as this research will illustrate. Since the Shan consumption of Thai CCWW involves a cross-cultural translation, it has demystified the common idea of the Tai brotherhood as one

title: Techonology transfer in Japanese electronics companies in Thailand

description: The electronics industry in Thailand is the leading sector in the Thai economy where the Japanese investments are made significantly paralleling to the automobile industry. In order to achieve the sustainable development, the Thai government has introduced several policies to promote technology transfer. Despite such efforts, much of what they get relates to adaption and technical support rather than innovation. The study aims to improve understanding about the actual practice of technology transfer at intra-firm level in the Japanese electronics companies in Thailand and to provide some policy implications for the Thai agencies concerned for the better application of the technology transfer in the future. The study adopted the measurement of technological capability, which was used in the previous studies, and summarized the characteristics of the technology transfer in the Japanese electronics companies in Thailand by collecting primary data from eleven companies and by interviewing some parent companies to support the data obtained from questionnaires. The results showed that the level of technology transfer of the Japanese electronics companies in Thailand remains at the lower level because of the nature of the products and human resources. The policy implications arising from the study are to have more R&D activities by providing more incentives, and investment in human resource development in the middle and long term

title: Effect of intensive education on frequency and quality of hand washing among households with influenza positive child in urban, Thailand

description: Background: Limited studies illustrated the effect of intensive education on hand washing behaviors in Thai households. We examined the effect of intensive hand washing education on self-reported frequency (FHW) and measured-quality of hand washing (QHW) as well as determined the change of score on instruments designed to measure knowledge, attitude and practice (KAP) of hand washing relevant to influenza. Methods: We provided intensive hand washing education in households between April 2007 and July 2009 as a component of a household-randomized control trial of interventions to reduce influenza transmission. We assessed behaviors among members of households (aged &gt; 7 years) with a confirmed influenza infected child enrolled in control (group 1) and hand washing (group 2) arms. Group 1 received routine health education on home visit day 0/1. Group 2 received 30 minutes education on influenza, benefits of hand washing, individual hand washing training and supplies on home visit day 0/1, 3 and 7 and was asked to record frequency of hand washing daily. We compared FHW at 7 days post-education between groups, using self-reported diary and compared QHW between groups by observation. We also compared change of FHW, QHW, KAP and hand washing procedure on 4 practices that include i) use of soap, ii) technique of cleaning area of hands, iii) use of clean towel/paper for drying hands and iv) duration between pre and 90 days post-education in group 2. Results: On day 7, group 1 (n[subscript 1] =135) reported 3.9 hand washing episodes/day, while group 2 (n[subscript 2] =140) reported 5.7 hand washing episodes/day (p

title: Internationalization of Thai silk

description: The present study aims to investigate the internationalization of Thai silk in terms of its international market and factors that make it internationalized. Some part of the data used in the analysis was taken from governmental documents. The other part was collected from five hundred foreign customers of Thai silk by using questionnaires and five Thai silk shop owners dealing with the industry and business of Thai silk by interviewing. Descriptive statistics was used to determine how much Thai silk has been internationalized and how much it is accepted by foreigners. The result of the analysis reveals that over the past six decades, more than thirty countries around the world have imported Thai silk for use in fashion and home decoration. Thai silk export has generated an income over 40,000 million baht for the country. It is found that there are four main factors that make Thai silk developed to the international level. They are: (1) support from important organizations divided into two kinds; internal support divided into public and private organizations, which play an important role in prompting Thai silk industry, and external support which helps ensure the growth Thai silk industry; (2) the effect of world political and economic situation, which affects the export of Thai silk by changing the purchasing power of the world customers; (3) the great variety of designs of Thai silk, which are composed of both traditional and modern patterns; (4) the adaptation of Thai silk to suit foreigners’ taste and preferences. Thai silk has adapted both its designs and functions; i.e., its designs have been more westernized and its function has been expanded from being used for clothing to being used for home furnishing

title: Utilization of modified montmorillonite and modified bamboo charcoal power as fillers in chitosan films

description: Chitosan/modified montmorillonite composite films and chitosan/modified bamboo charcoal composite films were prepared by blending chitosan with either modified montmorillonite or modified bamboo charcoal and forming the composite film by using a spin coater machine. The chitosan composite films contained contents of modified montmorillonite or modified bamboo charcoal varying from 0 to 2% (w/w). The morphological, structural and functional properties of these composite films were evaluated. The X-ray analysis showed that the modification of montmorillonite with depolymerized chitosan at molecular weight of 15 kDa appeared to induce the intercalation occurred in the modified montmorillonite. FTIR analysis confirmed that nitric acid oxidized some areas of bamboo charcoal particles during refluxing, leading to formation of carboxylic acid groups on the surface of the bamboo charcoal particles. Investigation of the mechanical properties of these composite films revealed that the tensile strength and rigidity were both found to increase, whilst the elongation at break decreased, with increasing either virgin or modified montmorillonite and bamboo charcoal in chitosan composite films. Inclusion of either unmodified montmorillonite or modified montmorillonite in chitosan films decreased the water and oil absorption of the composite films. Oil, and especially water, absorption of the chitosan/modified bamboo charcoal composite films increased with inclusion of either unmodified bamboo charcoal or modified bamboo charcoal in chitosan films. Inclusion of either modified montmorillonite or modified bamboo charcoal into chitosan films enhanced the thermal stability of chitosan composite films. SEM micrographs showed a good dispersion of modified montmorillonite and bamboo charcoal particles in chitosan matrix up to 0.5% (w/w), while some aggregation of montmorillonite or bamboo charcoal were observed at the content starting of 1% (w/w) of the chitosan composite films. The growth of Colletotrichum gloeosporiodes was completely inhibited by chitosan and chitosan composite films

title: A peer-drinking group brief motivational intervention for reducing alcohol use and consequences

description: Alcohol consumption, particularly among young males, is an important global health problem. Adverse outcomes include injuries secondary to drunk-driving, physical aggression and violence, increased risks of illicit drug use, crime, and longer term risks such as alcohol dependence and depression. There are no data available to evaluate the extent to which interventions are effective in reducing alcohol consumption and consequences among young males in Thailand. We sought to examine the efficacy of a peer-drinking group brief motivational intervention (PD-GMI) among Thai male undergraduates. Used a quasiexperimental study design involving two student groups with assessments at baseline and at two follow-up sessions was used. Participants were students enrolled in two public universities and who reported alcohol consumption during the current academic year. Students in one university were assigned to an assessment-only study group (n=110); and students at the other university were assigned to a 2-hour PD-GMI intervention (n=115). Students receiving the intervention had significant reductions in mean AUDIT scores; 50.4% at baseline to 1-month and 61.2% at baseline to 3-month post-intervention. Their mean RAPI scores were also reduced; 42.0% at baseline to 1-month and 42.9% at baseline to 3-month postintervention. This intervention decreased significantly AUDIT and RAPI over time compared to the control group after adjusting for baseline difference. These results suggest the efficacy of the PD-GMI for reducing alcohol consumption and consequences among Thai male students

title: The determination of patient effective dose in transarterial oily chemo embolization (TOCE) procedure using digital flat-panel system

description: Transarterial Oily Chemo Embolization (TOCE) is the procedure producing high dose to both patient and staff. Radiation skin injury to patient was reported by this interventional procedure. Therefore, the avoidance of skin injury during the procedure is needed. The objective of this study is to determine patient effective dose at the skin during TOCE procedure for Hepatocellular Carcinoma (HCC) using a new angiographic unit with a digital flat-panel system and the relationship between the patient effective doses measured by Unfors PSD and the dose area product (DAP) values. The patient effective doses (ED) were determined during TOCE procedure using the digital Flat-panel system, Philips Allura FD 20 at Vascular and Interventional Radiology Unit, King Chulalongkorn Memorial Hospital. The system is equipped with the dose-area-product (DAP) and used to determine the average entrance surface dose (ESD) for each procedure. The peak ESD were evaluated by the solid state dosemeter; Unfors Patient Skin Dosemeters (PSD) placed on patient back at three regions at left, middle, and right portions of the liver. The patients ED were calculated in sixty-nine patients in May-November 2009. The average + SD (range) fluoroscopic time was 16.06+ 11.26 (3.38-59.13) min, average number of frames from DSA (Digital Subtraction Angiography) was 180.81+94.59 ( 75-618), the number of frames from x-per CT with the range was 224 -1114. The average ESD determined by DAP was 222.6+114.6 (22.58-537.43) Gycm2. The average ESD determined by Unfors PSD was 1004.2+565.11 (192.6-3145.29) mGy. The average ED determined by DAP was 9.70+5.27 (1.11 - 23.6) mSv. The peak ED at the skin above the liver determined by Unfors PSD was 10.04+5.65 (1.93-31.45) mSv. The average of ED at left lobe of liver was 9.68+5.5 (1.75- 31.4) mSv, the middle lobe was 8.48+5.13 (1.21 - 28.78) mSv and the right lobe was 5.72+3.55 (0.64 -16.31) mSv. The DAP-to–effective dose conversion factors were 0.043 mSv.Gy-1cm-2. Discussion and Conclusion: The solid state dosemeter is most suitable for entrance surface dose measurement for the small size of detector and easily use. There was no need to estimate the surface area exposed as in DAP method. Two from sixty-nine patients received the entrance surface dose from TOCE procedure using Digital flat-panel system exceeding the threshold for radiation skin injuries which confirmed by both dosemeters.

title: Nanogold supported on amido-amidoxime functionalized silica for adsorption and catalytic oxidation of toluene

description: Nanogold supported on amido-amidoxime functionalized silica (Au-Ami-SiO₂) was prepared by a simple mixing of amido-amidoxime functionalized silica in HAuCl₄ solution. Au-Ami-SiO₂ was characterized by X-ray diffraction (XRD) technique and surface area analyzer. Toluene vapor adsorption on Au-Ami-SiO₂ was studied. The adsorption capacity was measured by a fixed bed system at ambient temperature using argon as carrier gas. The effects of contact time, flow rate and adsorbent dose on adsorption capacity were investigated. Adsorption capacity increased with increasing of contact time, and decreased with the increase in flow rate and adsorbent dose. The maximum adsorption capacity of 1.36 g g¯¹ was obtained at 45 min contact time, 40 mL min¯¹ flow rate and 0.05 g of adsorbent. Catalytic oxidation of toluene vapor using Au-Ami-SiO₂ was investigated under air atmosphere. The effects of reaction temperature and toluene concentration were investigated in two systems; (i) in the continuous system, reaction temperature and toluene concentration were studied in the range of 25 - 175 ℃ and 190 - 685 mg m¯³, respectively. The highest percentage removal was 53.06 ± 0.04 % at 685 mg m-3, at 175 ℃ and (ii) in the equilibrium system, the oxidation temperature was studied in the range of 25 - 275 ℃ with toluene concentration fixed at 685 mg m¯³, the highest percentage removal was 87.11 ± 0.15 % at 275 ℃. CO₂ appeared firstly

title: A development of webquest modules to enhance English reading and writing abilities and learning engagement of undergraduate engineering students at Rajamangala University of Technology Phra Nakhon, North Bangkok Campus

description: The research study was aimed at fulfilling four objectives: (1) to develop the WebQuest modules for "Technical English" course for enhancing students' English reading and writing abilities, (2) to investigate the effect of the integration of the developed WebQuest modules on reading and writing abilities of undergraduate engineering students, (3) to examine the effect of the integration of developed WebQuest in enhancing student engagement, (4) to examine the students' perceptions of the developed WebQuest modules. The study was conducted with a sample group of 40 undergraduate engineering students who were enrolled in the "Technical English" course in the first semester of the academic year 2008 at Rajamangala University of Technology Phra Nakhon, North Bangkok. The experiment was carried out for 14 weeks. Data were collected using the reading and writing achievement tests administered before and after the implementation of the developed WebQuest modules. The gained scores obtained from the pretests and the posttests were compared using paired sample t-test and Hedges' g effect sizes to measure the effects and the magnitudes of the effects caused by the developed WebQuest modules. In addition, a self-rating engagement questionnaire was distributed to the participants at the end of the course to investigate student learning engagement. Students' logs and teacher's diary were also employed during the implementation to collect qualitative data concerning students' perceptions of the WebQuest modules. A semi-structured interview was an additional means to investigate students' perceptions of the developed modules. Findings revealed that there was a statistically significant difference between the mean scores students obtained from the pretests and posttests of reading and writing achievement at a significance level of 0.05. The effect sizes calculated by using Hedges' g yielded the value of 1.19 and 2.17, respectively, which were considered large. The data obtained from the self-rating engagement questionnaire indicated that the level of the students' behavioral, affective and cognitive engagement was high when studying with the WebQuest modules. According to the qualitative data obtained from the students' logs and teacher's diary, the students revealed that the WebQuest modules were useful for enhancing their reading and writing abilities and the majority had positive perceptions of the implementation of these instructional modules.

title: Structural property and interaction between single-walled carbon nanotube and doxorubicin using molecular dynamics simulations

description: Molecular dynamics simulations in aqueous solution were carried out to understand molecular properties of the anticancer drug, carried by single-walled carbon nanotube (SWCNT). The doxorubicin drug, DOX, in free form (DOXfree) and its complexes both inside (DOXin-SWCNT) and outside (DOXout-SWCNT) the pristine SWCNT were chosen to be the three modeled studied. It was found, as expected, due to the collaborative interaction with the surface of the tube that the DOX in the DOXin-SWCNT is much less flexible than that of the other two forms. The DOX in both complexes was also observed to form the aromatic stacking interaction with the SWCNT surface. Interestingly, the DOX in the DOXin-SWCNT and DOXout-SWCNT complexes were found to move from one end to the other of the SWCNT, parallel to the tube surface at the distance (from the center of mass of the drug to the tube surface) of 4.5 Å and 4.0 Å, respectively. In addition, simulations were also extended to the DOX, complexed inside the –OH and –COOH functionalized SWCNTs. The results show that no significant difference was found between the structural data obtained from the functionalized SWCNTs (OH-SWCNT and COOH-SWCNT) and those of the pristine SWCNT.

title: Minimum rank of graphs

description: The minimum rank over a field F of a graph G is the smallest possible rank among all symmetric matrices over F whose ( i , j )th entry ( i ≠ j ) is nonzero whenever ij is an edge in G and is zero otherwise, where zero is the additive identity of F. A universally optimal matrix for a graph G is an integer symmetric matrix A such that every off-diagonal entry of A is 0, 1, or –1 and for all fields F, the rank of A is the minimum rank over F of G which is isomorphic to the graph of A. The fan graph, the book graph, the lotus graph and the hanging bridge graph are introduced and the minimum rank of these graphs over any field are presented. We use universally optimal matrices for these graphs to establish field independence of minimum rank. Examples verifying lack of field independence for some graphs are provided.

title: Corporate governance and insider trading : evidence from Thailand

description: This research investigates the relationship between abnormal return from insider trading and corporate governance. It also tests whether insiders earn higher abnormal returns from trading stocks prior to earning announcements than the other periods. The samples of the study are all insider trades filed with Security Exchange Commission during the year 2006-2007. This research has found asymmetric relationship between corporate governance and abnormal return from insider trades. For insider sales, there is negative relationship between corporate governance and abnormal return. For insider purchases, there is positive relationship between corporate governance and abnormal return. Next, this study has found that insider trades prior to earning announcements yield significantly higher abnormal return than trades occurring during other periods. Thus, blackout period regulation which prohibits any insider trades during the period prior to firms’ earning announcements should be valuable to Thai capital market.
