Blood plasma minerals and their effects towards the fertility in 136 cows randomly selected from 26 dairy farms in central Thailand were studied. An average of 8.60 mg% Ca, 5.97 mg% P, 2.45 mg% Mg, $85.9{\mu}g%$ Cu, and $160.9{\mu}g%$ Zn in plasma was observed. Compared to the critical deficient values, 24.3, 10.3, 11.8, 28.7 and 0.0% of the surveyed cows obtained the respective elements in plasma below the standard levels. No significant difference (p >.05) in plasma concentrations of Ca, P, Mg and Zn for the low fertile (conception rate > 3) and fertile (conception rate < 3) cows was found. However, plasma Cu of the low fertile cows (averaged $77.2{\mu}g%$) was lower (p <.01) than that of the fertile ones (averaged $91.12{\mu}g%$). Additionally, it is observed that 47.1% of the cows with the low fertility problem obtained plasma Cu below the 65.0 pg% critical deficient value.

Background: Esophageal cancer is one of the major health concerns in Southeast Asian countries, including Thailand. However, only a limited number of studies have been reported from this region. This study was designed to evaluate the prevalence, clinical characteristics and survival rate of esophageal cancer in Thailand. Materials and Methods: Clinical information, histological features and endoscopic findings were collected from a tertiary care center in central region of Thailand between September 2011- November 2014 and reviewed. Results: A total of 64 esophageal cancer patients including 58 men and 6 women with mean age of 62.6 years were enrolled. Common presenting symptoms were dysphagia (74%), dyspepsia (10%) and hematemesis (8%). Mean duration of symptoms prior to diagnosis was 72 days. Esophageal stenosis with contact bleeding was the most common endoscopic finding (55.6%). The location of cancer was found in proximal (16%), middle (50%) and distal (34%) esophagus. Squamous cell carcinoma was far more common histology than adenocarcinoma (84.2% vs 10.5%). However, esophageal adenocarcinoma was significantly more common than squamous cell carcinoma in distal area of esophagus (100% vs 22.9%; p=0.0001, OR=1.6, 95%CI=1.1-2.2). Esophageal cancer stages 3 and 4 accounted for 35.2% and 59.3% respectively. Overall 2-year survival rate was 20% and only 16% in metastatic patients. Conclusions: Most esophageal cancer patients in Thailand have squamous cell carcinoma and nearly all present at advanced stage with a grave prognosis. Screening of high risk individuals and early detection might be important keys to improve the survival rate and treatment outcome in Thailand.

Plasmodium vivax is usually considered morbidity in endemic areas of Asia, Central and South America, and some part of Africa. In Thailand, previous studies indicated the genetic diversity of P. vivax in malaria-endemic regions such as the western part of Thailand bordering with Myanmar. The objective of the study is to investigate the genetic diversity of P. vivax circulating in Southern Thailand by using 3 antigenic markers and 8 microsatellite markers. Dried blood spots were collected from Chumphon, Phang Nga, Ranong and, Surat Thani provinces of Thailand. By PCR, 3 distinct sizes of $PvMSP3{\alpha}$, 2 sizes of $PvMSP3{\beta}$ and 2 sizes of PvMSP1 F2 were detected based on the length of PCR products, respectively. PCR/RFLP analyses of these antigen genes revealed high levels of genetic diversity. The genotyping of 8 microsatellite loci showed high genetic diversity as indicated by high alleles per locus and high expected heterozygosity ($H_E$). The genotyping markers also showed multiple-clones of infection. Mixed genotypes were detected in 4.8% of $PvMSP3{\alpha}$, 29.1% in $PvMSP3{\beta}$ and 55.3% of microsatellite markers. These results showed that there was high genetic diversity of P. vivax isolated from Southern Thailand, indicating that the genetic diversity of P. vivax in this region was comparable to those observed other areas of Thailand.

Azuki bean has never been commercially grown in Thailand, due in part to a lack of suitable varieties. A core collection of 114 azuki bean accessions, originally from different parts of China(northern, central, southern) representing the germplasm of Chinese land races, were evaluated in the experimental field of the Institute of Vegetable Crops, Jiangsu Academy of Agricultural Sciences, China from June to October 2004. The same experiment was repeated at Kamphaeng Saen campus of Kasetsart University, Thailand from February to May 2005. Yield, yield components, and agronomic traits were recorded in all accessions in order to identify certain genotypes for further investigation. The statistical parameters that were used as indicators of phenotypic variation were mean, coefficient of variability(CV), correlation coefficient(r), range, mean difference, and phenotypic clustering of the accessions. The results indicated that the azuki bean varieties planted in Kamphaeng Saen were shorter, earlier in growing duration, and lower in plant height, seed yield per plant, 100-seed weight, and pods per plant as compared to when they were grown in China. This discrepancy was caused largely by the combined effect of temperature, rainfall, and day length. The traits that were rather stable in both locations were branches per plant and seeds per pod. Azuki bean varieties from northern China showed higher response to the changing environments compared with those from central and southern China. Some agronomic traits showed high correlation coefficient between the environments in Thailand and China. The CV of agronomic traits in both locations were ranked in descending order as follows: seed yield per plant, pods per plant, branches per plant, plant height, 100-seed weight, seeds per pod, and growing duration. The CV of seeds per pod and branches per plant were almost the same in both locations. Yield per plant in China correlated well(r=0.75) with pods per plant, but not with the other traits. Based on their response to both environments, the azuki bean accessions can be broadly divided into four groups, viz. northern 1, northern 2, central, and southern. This implied that there was more diversity, but probably less stability among the accessions originating from northern China.

The study investigates how financial markets respond to a shock to tone and semantic similarity of the Bank of Thailand press releases. The techniques in natural language processing are employed to quantify the tone and the semantic similarity of 69 press releases from 2010 to 2018. The corpus of the press releases is accessible to the general public. Stock market returns and bond yields are measured by logged return on SET50 and short-term and long-term government bonds, respectively. Data are daily from January 4, 2010, to August 8, 2019. The study uses the Structural Vector Auto Regressive model (SVAR) to analyze the effects of unanticipated and temporary shocks to the tone and the semantic similarity on bond yields and stock market returns. Impulse response functions are also constructed for the analysis. The results show that 1-month, 3-month, 6-month and 1-year bond yields significantly increase in response to a positive shock to the tone of press releases and 1-month, 3-month, 6-month, 1-year and 25-year bond yields significantly increase in response to a positive shock to the semantic similarity. Interestingly, stock market returns obtained from the SET50 index insignificantly respond to the shocks from the tone and the semantic similarity of the press releases.

The expected launching countries are selected based on the state and strategy of businesses undertaking by LH, then the legal systems for urban development of those countries are investigated and analyzed to be used as basic data for advancing to oversea urban development. The results are showing as follows. First, on the basis of the advancing priority, and the level and obtaining possibility of legal system for urban developments, Bangladesh, Thailand, Dominican Republic, and Venezuela are selected to be investigated among the countries of Central and South America and Asia to where expected to be advanced. Second, most of the selected countries establish and promote the national housing policies by their own National Housing Authority. For example, First-Home Policy and National Housing Development Strategy, etc. are established in Thailand, and National Housing Authority takes charge of the housing development for low-income bracket. Third, the laws and project procedures are investigated, then compared to the similar laws of Korea. The common "Land Allocation Act" is legislate in Bangladesh and Thailand, for example, "Land Allocation Act" and "Town and City Planning Act" are enacted in Thailand. On the other hand, the laws for urban and housing developments vary from country to country those are located in Central and South America. Meanwhile, it is verified that "Act on Planning and Use of National Territory" of Korea is similar to the "Town and City Planning Act" of Thailand.

In this paper, we present the different characteristics of NDVI fluctuation pattern between irrigated and non-irrigated area in Suphanburi province, in Central Thailand. For non-irrigated rice cultivation area, there is a strong correlation between NDVI fluctuation and peak rainfall, while there is a lower correlation with irrigated area. In this study, the 'peak detector' classifier was developed to identify the area of non-irrigated and irrigated cropping and its cropping intensity (number of crops per year). This classifier was created based on cropping characteristics such as number of crops, time or planting period of each crop and its relationship with the peak of rainfall. The classified result showed good accuracy in identification irrigated and nonirrigated rice cultivation areas.

The purpose of this study is to evaluate the potential application of TERRA-ASTER data in Thailand. ASTER VNIR, SWIR and TIR data covering greater Bangkok and Chiangmai province were processed with various techniques in the spatial domain to study the applicability to various disciplines. ASTER data was also combined with other satellite data in order to utilize multi-sensor methods. It was found that VNIR data can clearly identify urban pattern including road network and vegetation index. While SWIR and TIR data can well separate between urban and non urban area and TIR data can differentiate among thermal surfaces. Furthermore, dense urban areas such as central business area could be highlighted. Land utilization, vegetable distribution and differences of temperature distribution were investigated.

Taeniasis is prevalent in all regions of Thailand, except the South. Infections were more frequently found in males than females of any age from 7-83 years. Taenia saginata is the most common species throughout the country. Taenia asiatica was reported only in the province of Kanchanaburi in the Central region. Co-infections, with Taenia solium and T. asiatica or T. solium and T. saginata, were found. Hybridization between T. asiatica and T. saginata is evidence that co-infection is never found between these 2 species. Finding more than 1 worm in a single patient was not entirely rare. Genetic variation was found without correlation to its geographic distribution in T. saginata, whereas no variation was found in T. asiatica.

Fifty-six indigenous and twenty nine exotic mulberry varieties were screened against powdery mildew, Myrothecium leaf spot, Pseudocercospora leaf spot, sooty mold and bacterial leaf spot for a period of three years under field condition. The percent disease index (PDI) was recorded during peak season of the foliar diseases. Out of eighty-five varieties studied, ten varieties were highly resistant and eight were resistant to powdery mildew; six varieties were immune and seventy-eight varieties were highly resistant to Myrothecium leaf spot; sixty varieties were highly resistant and 21 were resistant to Pseudocercospora leaf spot; forty four varieties were highly resistant to sooty mold and two varieties were immune and fifty-eight were highly resistant to bacterial leaf spot. Lowest cumulatative disease index was observed in M. multicaulis (7.28) followed by Thailand lobed (7.85) and Italian mulberry (8.06).
