The aims of this study were to apply the Geo-information technology for coastal vulnerability assessment of Phetchaburi coast, which depended on seasonal changed (by influence of Southwest monsoon and Northeast monsoon). The assessment uses a coastal vulnerability index (CVI), consists of a physical environment vulnerability index (PVI) and the socio-economic vulnerability index (SVI) with 9 variables; coastal slope, mean tidal ranges, average wave height, rates of coastal erosion, population density, land use, built-up, transportation and coastal protection measures. The results showed, the different during monsoon had an indecisive difference effect on mean tidal ranges, average wave height, and changes in the coastline. However, the monsoon had effected to sand sediment of the beach. That increased in the Southwest monsoon and decreased in the Northeast monsoon. The level of vulnerability of the coastal area was shown by a map of CVI, with high coastal vulnerability areas having a size of 4.6 square kilometers (10.89% of the coastal surveillance area), mainly in Pak-Thale, Bang-Keaw and Chao-Samran. The moderate and the low coastal vulnerability areas have size of 31.29 square kilometers and 6.97 square kilometers, respectively. The variables that influence the vulnerability are land use, slope, erosion rate and population density. © 2015 Thai Society of Higher Eduation Institutes on Environment Source

A cadmium resistant rhizobacterium, Pseudomonas sp. PM2, was isolated from plant roots. It is highly resistant to cadmium toxicity. The minimum inhibitory concentrations of cadmium for Pseudomunas sp. PM2 is 2100 mg/L. Peeudomonas sp. PM2 produced high levels of sidenophore and rhamnolipid biosurfuctant in 74.88 μM of deferoxamine meiylate equivalents and 329.54 mg/L, respectively. It was able to remove cadmium ion in an aqueous solution by 69.84% at the initial cadmium ion concentration of 25 mg/L. Pseudomonas sp. PM2 significantln increased eadmium bioavailability in contaminated soil by increasing DTPA-extractable cadmium concentration or a biosvailable form of cadmium. The increase in cadmium bioavailability in soil helps to promote cadmium uptake by plants for cadmium phytoextraction. In addition, Pseudamonas sp. PM2 had no positive oe negative effects on seed germination and root elongation of Glycine max L. under the absence and presence of cadmium. Our findings suggest that Pseudomonas sp. PM2 could be useful in the further development of biological treatment of cadmium in contaminated water and soil. © 2015 Thai Society of Higher Eduation Institutes on Environment Source

Objective: Identify the difference of the nutritional status of Thai children from birth to 24 months of age using the national and international growth charts. Material and Method: The analytic sample was of 4,224 children from the Prospective Cohort Study of Thai Children (PCTC). Age-specific prevalence of malnutrition was estimated using the NCHS, WHO, and Thai growth charts. Results: Rapid growth faltering was found in both genders during the first two years, regardless of the reference, but the Thai charts reflected better Thai children. When using the Thai and NCHS charts, a steep fluctuation was observed in infancy, although the prevalence of wasting, underweight, and overweight between the references became narrower at 24 months. Meanwhile, the WHO standards identified a higher number of stunted children and showed a linear increasing trend of overweight with age, compared to the Thai reference. Conclusion: Although the Thai growth charts better reflect the Thai children, in consideration of a double burden of stunting and overweight in Thailand, the WHO standards can be used to identify Thai children at risk of stunting and overweight in the first two years of life. © 2016, Medical Association of Thailand.

During the past few decades, Thai women have learned how to extent their roles from a care taker of children and a household to natural resources and environmental protection and management in local and inter-regional communities. Due to the application of National Economic and Social Development Plans, rapid resource exploitation has brought in natural resource and environmental degradation all over the country threatening communal security. For this reason, there have been a number of emerging environmental leaders who want to correct directions of national development, especially Thai woman environmental leaders who are taking a successful role of environmental guardian in their communities. This research attempts to explore why they took leadership role in environment, how they work so successful as an environmental guardian, and what their next move is. During early 2013 till mid-2014, there are 28 Thai woman leaders who received the award of Thai Environmental Conservation Mother from the Faculty of Environment and Resource Studies, Mahidol University between 2004 and 2012. They were in-depth interviewed and collected data were preceded by content analysis. Their lessons learnt show that most leaders saved their communities’ environment and natural resources from the intervention of new development activities. Most of them had their parents as a good role model in environmental management who provide knowledge of morals and environmental ethics as a good basic of leadership while some shared their husband’s responsibility in the same matter. Significantly, teamwork is their working style with the assistance of public participation to hold teamwork and collaboration of the community. Almost all leaders had systematic working with talents of patience, gentleness and sensitivity. The working network also broadens their new information and knowledge between practitioners. In the same time, more than half of the leaders can prepare their successors from the younger generation who can continue environmental conservation of the community, while the rest cannot do it. This situation pushes some leaders find alternative succession process. © 2015, Thai Society of Higher Eduation Institutes on Environment. All rights reserved. Source
