  • Paragonimiasis is an important food-borne parasitic zoonosis caused by infection with lung flukes of the genus Paragonimus. Of the 7 members of the genus known in Thailand until recently, only P. heterotremus has been confirmed as causing human disease. An 8th species, P. pseudoheterotremus, has recently been proposed from Thailand, and has been found in humans. Molecular data place this species as a sister species to P. heterotremus, and it is likely that P. pseudoheterotremus is not specifically distinct from P. heterotremus. In this study, we collected metacercariae of both nominal species (identification based on metacercarial morphology) from freshwater crabs from Phetchabun Province in northern Thailand, Saraburi Province in central Thailand, and Surat Thani Province in southern Thailand. In addition, we purchased freshwater crabs imported from Myanmar at Myawaddy Province, western Thailand, close to the Myanmar-Thailand border. The DNAs extracted from excysted metacercariae were PCR-amplified and sequenced for ITS2 and cox1 genes. The ITS2 sequences were nearly identical among all samples (99-100%). Phylogenies inferred from all available partial cox1 sequences contained several clusters. Sequences from Indian P. heterotremus formed a sister group to sequences from P. pseudoheterotremus-type metacercariae. Sequences of P. heterotremus from Thailand, Vietnam, and China formed a separate distinct clade. One metacercaria from Phitsanulok Province was distinct from all others. There is clearly considerable genetic variation in the P. heterotremus complex in Thailand and the form referred to as P. pseudoheterotremus is widely distributed in Thailand and the Thai-Myanmar border region.

  • Safety of packaging foods has increasingly been a significant global issue in recent years. This paper aims to present the broad information and perspectives on food packaging safety in Thailand. This paper compiles the use of different packaging materials, their safety characteristics, and the regulations in Thailand in accordance with the world regulations. In addition, it covers the opinion of various parties related to food packaging in Thailand. Some scientific based results coupled with the interviewing and questionnaire data from the previous and ongoing researches are discussed here. This paper summarizes the food packaging safety in Thailand today and proposed the trends tomorrow along with the future world requirements.

  • In this article, an alternative analog multiplier circuit, using the translinear second-generation current conveyors with the external resistors. The realization method makes use of the inherited translinear loop of the current conveyor offering the positive-supply current that provides in the quartersquare algebraic identity. The proposed circuit operates in voltage mode and it achieves a high accuracy. The PSPICE simulation results confirm that the performances of the proposed multiplier circuit, such as dynamic range and accuracy, are agreed with the theoretical results.

  • This paper argues that Thailand's internal colonial model is facing severe challenges: no longer is it so possible to suppress local and regional identities, or to submerge ethnic difference in an all-embracing but potentially suffocating blanket of "Thainess." In recent decades, Thailand's diverse localities have become increasingly assertive. This is most acutely the case in the insurgency-affected southern border provinces of Pattani, Yala, and Narathiwat, but also applies in the "red' (pro-Thaksin) dominated North and Northeast. As the old ruling elite faces serious legitimacy challenges, Thailand's emerging post-colonial politics may require a radical rethinking of the relationship between center and periphery.

  • Purpose: Electric vehicle (EV) technology started in 2015 in Thailand. The Thai Government has indicated that 30% of all cars produced in Thailand by 2025 will be EVs. Using EVs in Thailand will reduce road pollution and increase energy efficiency, especially in major cities. Hence, the adoption of EVs in the country has been promoted. This study pointed out that social influence, facilitating conditions, perceived enjoyment, environmental concern, attitude, and perceived behavioral control are key factors affecting the behavioral intention to adopt EVs among logistic and distribution firms in Thailand. Research design, data, and methodology: 500 top management, middle management and purchasing managers of logistic and distribution firms in Thailand are surveyed. The study employed judgmental, convenience, and snowball sampling. Confirmatory Factor Analysis (CFA) and Structural Equation Model (SEM) are the main statistical tools for data analysis. Results: The results show that all determinants impact customers' willingness to adopt EVs, except perceived enjoyment and environmental control. Conclusions: The study proposes to promote the incentives by decreasing electricity prices and endorsing EVs purchase to accelerate the adoption of EVs in Thailand. Therefore, future policies should focus on behavioral intention toward EVs amongst logistic and distribution firms for enhancing the future of mobility in Thailand.

  • Raising dairy cattle for milk production has been promoted and supported by the Thai government in recent years. The extent to which dairy farmers in southern Thailand use the practices recommended by government officers is not known and was investigated in this study. With dairy farming in southern Thailand mainly concentrated in the Phatthalung province, the entire population of dairy farmers in this province was studied. A total of 114 dairy farmers were studied by personal interviews. The results showed that the farmers varied widely in their use of the practices for dairy production in southern Thailand. The study identified that the major problems in dairy production in southern Thailand were low rates of conception to artificial insemination, the high price of feedstuffs and a shortage of roughage in the dry summer months.
