  • Th Rach Gia Bypass Project, to be implemented under EDCF Loan VNM-12, constitutes a strategically important part of the Greater Mekong Sub-region Southern Coastal Corridor Project(the GMS-SCCP). The main goal of the GMS strategy is to promote sustainable economic growth, improve employment, and achieve poverty reduction by tapping the comparative advantages of Vietnam, Cambodia and Thailand. As a project manager who once took a responsible position for the completion of RGBP's detailed design, I would like to briefly introduce what our design team including the local sub-contractors had performed for the D/Design of this Project last year, especially in the field of highway, bridge and soft soil treatment method widely used in Mekong Delta area. With the performance of nearly two Projects due to the V.O. in one year on the prescribed time, it was a hard year but a rewarding one. To expand our horizon more about overseas projects, several recommendations for the brighter future of overseas projects are shown herein this paper.

  • We compared the efficacy and applicability of a modified formalin-ether concentration technique (M-FECT) to the conventional FECT (C-FECT) and the agar plate culture (APC) method for the detection of Strongyloides stercoralis larvae. For this purpose, we used 600 human fecal specimens collected in an endemic area of southern Thailand. In the M-FECT, we used 2 layers of wire meshes, instead of gauze, to avoid the loss by absorption/adhesion of larvae to the gauze during filtration, and we reduced the exposure time of S. stercoralis larvae in stool samples to formalin. By such simple modifications, the efficacy of M-FECT has become comparable to APC and was much better than that of C-FECT for the diagnosis of strongyloidiasis.

  • Purpose: To study the patient load, treatment pattern, survival outcome and its predictors in patients with brain metastases treated by radiotherapy. Materials and Methods: Data for patients with brain metastases treated by radiotherapy between 2003 and 2007 were collected from medical records, the hospital information system database, and a population-based tumor registry database until death or at least 5 years after treatment and retrospectively reviewed. Results: The number of treatments for brain metastases gradually increased from 48 in 2003 to 107 in 2007, with more than 70% from lung and breast cancers. The majority were treated with whole brain radiation of 30 Gy (3 Gy X 10 fractions) by cobalt-60 machine, using radiation alone. The overall median survival of the 418 patients was 3.9 months. Cohort analysis of relative survival after radiotherapy was as follows: 52% at 3 months, 18% at 1 year and 3% at 5 years in males; and 66% at 3 months, 26% at 1 year and 7% at 5 years in females. Multivariate analysis demonstrated that the patients treated with combined modalities had a better prognosis. Poor prognostic factors included primary cancer from the lung or gastrointestinal tract, emergency or urgent consultation, poor performance status (ECOG 3-4), and a hemoglobin level before treatment of less than 10 g/dl. Conclusions: This study identified an increasing trend of patient load with brain metastases. Possible over-treatment and under-treatment were demonstrated with a wide range of survival results. Practical prognostic scoring systems to assist in decision-making for optimal treatment of different patient groups is absolutely necessary; it is a key strategy for balancing good quality of care and patient load.

  • A Convergence Research Study of Southern Fujian Region in China during the Song Dynasty analyzing the Export of Ceramics During the Song Dynasty in China ceramics made in the Southern Fujian (also known as Minnan) region were exported to different countries in Southeast Asia including the Philippines, Thailand and more. They were even exported to Korea, Japan and through trade they traveled as far as Africa. Ceramics was one of the three main sea route export item of China at the time and there were active commercial trading between Korea as well as other countries, enabling ceramics to develop rapidly. The harmonious reciprocal relationship between the geographical, political, cultural, economical characteristics of Southern Fujian enabled a unique type of celadon ware widely recognized to develop. Ceramics of this region is one of a kind in terms of history when we relate it to research on integrating different elements. It suggests a unique convergence of culture when we study its forms and its industrial characteristics. The study attempts to analyze the influence of geography, politics, economy and culture on the different phenomena found in ceramics. Different paradigms associated with changes of environment reflect on continued development in the field of ceramics.

  • This paper exhibits the concept of Triple Helix model to explain and link university-industry-government (Triple Helix) connections to national innovation systems theory. The driver of this paper is to test the dynamics of Triple Helix concept under national innovation system in the Association of South East Asian Countries (ASEAN)-5 economies. Panel econometric analysis with cross-sectional dependence (CD) test is applied to investigate the relationship amongst Triple Helix variables. The empirical analysis employs innovation indicators of five founding ASEAN countries namely Malaysia, Indonesia, Singapore, the Philippines and Thailand for the period of 2000-2015 from an existing WDI and WCY database. Econometric results support the two research questions of this study; firstly, there is a significant relationship between innovation outcome and its key drivers under Triple Helix context of National Innovation System in ASEAN-5 economies; secondly, the extent of the relationship among government R&D expenditure with high-tech productions are positive and significant while new ideas coming from universities as scientific publications and high-tech production have positive relationship but not significant yet in ASEAN-5 countries. Overall labor productivity is positive and significant with innovation outcomes in ASEAN-5.

  • The tendencies for teleconnection with a time lag and other characteristics of Korean summer droughts have been investigated and some clues to predict the drought occurrences several months before have been found. First, the May and June droughts in Korea are simultaneous with those over the northwestern part of Korea owing to the relation with the baroclinic wave. However, the July and August droughts occur over the mid-latitudes or southern part of Korea owing to the relation with the Changma front. Second, several months before the MJJA droughts in Korea, it is found that the effective drought index (EDI) over particular areas (hereafter, referred to as the omen areas) is large. Thailand, Carolina Island, Mongolia, and Central Bengal Bay were selected as the omen areas. Third, when the monthly minimum EDI (MME) of the omen area in winter is more than 0.7, it signifies that the precipitation is above normal, Korea has almost always experienced a summer drought. However, the droughts occurring with this type of relationship only represent half of the MJJA droughts in Korea. Fourth, the relationships between the Korean drought and the precipitation over omen areas in low latitudes are not valid over all the eight precipitation areas in Korea, but only over Areas I, II, and III, where heavy rains occur during spring and summer.

  • The purpose of this study is to prove the positive effect of mind and body healing through the modified meditation method of Southern Buddhism as a systematic practice to concentrate or empty consciousness of the Buddhist temple in Dhammakaya, Thailand. To investigate the effects of the program on the participants, the experimental measurement tools in this study include the Immeasurable scale, spirituality scale, simple mental test scale, and blood pressure scale, pulse meter, thermometer, and recorder. When the measured values were compared with the corresponding t-test, there were some differences before and after the measurements based on the significance probability p <0.05. As a result, there was a significant correlation between spiritual support scale and the Immeasurable scale. In addition, the results of analyzing the data through interviews showed that the body and physiologically effective concentration was well after the meditation experience, and the intention to actively utilize this meditation method was confirmed. In this study, it was confirmed that there was a positive effect of the Samata practice method of Concentration meditation(CM), and thus the theoretical and experimental effects of intensive meditation were presented. I hope that these studies will accumulate and follow-up studies will be conducted through intensive meditation as a healing effect.

  • Several species of the fungi were isolated from cassava(Manihot esculenta Gruntz) starch which had formed into pellet, those had been stored for a while in southern part of Thailand. The species of Rhizopus, Aspergillus niger, and Aspergillus fumigatus were identified. The experimental results are as follows; Dry weight increases were checked during the static liquid culture with modified Czapek Dox medium to which cassava starch was partly replaced to sugar, Aspergillus niger and Aspergillus fumigatus had grown more than Rizopus species when 6% cassava starch was replaced to sugar and had been cultured for 72 hours. Amounts of mycelial protein of Aspergillus niger were checked, the highest amount was shown in 6% cassava starch involved medium. When nitrogen sources were varied such as ammonium sulfate or urea against sodium nitrate, there was no significant difference in mycelial production. Alpha amylase activity of each fungus isolated here was checked, those of Aspergillus niger have shown the highest peak at 72 hours.

  • Background: Urinary 1-hydroxypyrene (1-OHP) was selected as a biomarker of polycyclic aromatic hydrocarbons (PAHs) to explore the accumulation level in the bodies of workers at rubber smoke sheet factories in southern Thailand. Methods: Spot urine samples were taken from four groups of workers from June 2006 to November 2007. The nonexposure or control groups included habitual cigarette smokers and nonsmokers. The other two groups were workers exposed to particle-bound PAHs from rubber wood smoke and they were nonsmokers. All spot urine samples were analyzed for 1-OHP and creatinine levels. Results: The mean${\pm}$standard deviation urinary 1-OHP in the control group of habitual smokers and the nonsmokers was $0.24{\pm}0.16{\mu}mol/mol$ creatinine and not-detected to $0.14{\mu}mol/mol$ creatinine, respectively. In the workers, the 1-OHP levels on workdays had no significant difference from the 1-OHP levels on the days off. The yearly average 1-OHP level was $0.76{\pm}0.41{\mu}mol/mol$ creatinine whereas the average 1-OHP level during 10 consecutive workdays was $1.06{\pm}0.29{\mu}mol/mol$ creatinine (p > 0.05). Conclusion: The urinary 1-OHP levels of workers exposed to PAHs were high. The accumulation of 1-OHP in the body was not clear although the workers had long working hours with few days off during their working experience. Therefore, a regular day off schedule and rotation shift work during high productive RSS should be set for RSS workers.

  • Background/Aims: Hepatitis B virus reactivation (HBVr) following chemotherapy (CMT) is well-known among hematologic malignancies, and screening recommendations are established. However, HBVr data in solid organ malignancy (SOM) patients are limited. This study aims to determine hepatitis B surface antigen (HBsAg) screening rates, HBV prevalence, and the rate of significant hepatitis caused by HBVr in SOM patients undergoing CMT. Methods: Based on the Oncology unit's registration database from 2009-2013, we retrospectively reviewed records of all SOM patients ≥18 years undergoing CMT at Songklanagarind Hospital who were followed until death or ≥6 months after CMT sessions. Exclusion criteria included patients without baseline liver function tests (LFTs) and who underwent CMT before the study period. We obtained and analyzed baseline clinical characteristics, HBsAg screening, and LFT data during follow-up. Results: Of 3,231 cases in the database, 810 were eligible. The overall HBsAg screening rate in the 5-year period was 27.7%. Screening rates were low from 2009-2012 (7.8-21%) and increased in 2013 to 82.9%. The prevalence of HBV among screened patients was 7.1%. Of those, 75% underwent prophylactic antiviral therapy. During the 6-month followup period, there were three cases of significant hepatitis caused by HBVr (4.2% of all significant hepatitis cases); all were in the unscreened group. Conclusions: The prevalence of HBV in SOM patients undergoing CMT in our study was similar to the estimated prevalence in general Thai population, but the screening rate was quite low. Cases of HBVr causing significant hepatitis occurred in the unscreened group; therefore, HBV screening and treatment in SOM patients should be considered in HBV-endemic areas.
