Objective: To evaluate the potential of local mosquitoes to act as vectors for dengue transmission in ***: Serotype 2 Th NH28/93 was used to test the dengue susceptibility profiles of Aedes flavopictus miyarai(Ae. f. miyarai), Aedes galloisi(Ae. galloisi) and Aedes albopictus(***), which were collected in Japan. We used Aedes aegypti from Thailand as a positive control. The mosquitoes were infected with the virus intrathoracically or orally. At 10 or 14 days post infection, the mosquitoes were dissected and total RNA was extracted from their abdomens, thoraxes, heads and legs. Mosquito susceptibility to dengue virus was evaluated using RT-PCR with dengue virus-specific primers. Differences in the infection and mortality rates of the different mosquito species were tested using Fisher's exact probability ***: The infection rates for dengue virus administered intrathoracically to Ae. f. miyarai,Ae. galloisi and Aedes aegypti mosquitoes were identical by RT-PCR on Day 10 post *** of the body parts we tested were RT-PCR-positive for dengue virus. For the orally administered virus, the infection rates in the different body parts of the Ae. f. miyarai mosquitoes were slightly higher than those of Ae. albopictus mosquitoes, but were similar to the control mosquitoes(P > 0.05). The mortality rates for Ae. f. miyarai and Ae. albopictus mosquitoes were similar(P = 0.19). Our data indicated that dengue virus was able to replicate and disseminate to secondary infection sites in all of the four mosquito species(Japanese and Thai).Conclusions: Ae. albopictus is a well-known candidate for dengue transmission in Japan. However, our data suggest that Ae. f. miyarai from Ishigaki Island(near Okinawa Island) and Ae. galloisi from Hokkaido(Northern Japan) should also be regarded as potential vectors for dengue transmission in these regions. Further studies on these mosquitoes should be conducted.

Sustainability of Local Food Supply Chain in the New Theory Agriculture

引用

Journal of Modern Accounting and Auditing 2011年第7期7卷 749-757页

作者： Chutchai Suksa-ard Morrakot raweewan Thammasat University Thailand

World food production and its economic have rapidly grown over a decade; and number of supply chain management research has also increased in this field. However, this development relates to natural resources depletion and deterioration of quality of life in rural population, especially in smallholder farmers. Thailand has practiced the New Theory Agriculture （NTA）, one application aligned with sufficient economy. This theory not only remedies damaged natural resources but also helps smallholder farmers to improve quality of life; and it is analogous to local food supply chain theory, that is well-known in western countries. However, NTA has not been measured its sustainability. Following sustainable food criteria and sustainable agriculture criteria, this paper uses an Indicator of Sustainable Agricultural Practice （ISAP） to measure sustainability at farm level of small rural community＇s network called Inpaeng, a case study that has practiced NTA. The result of assessment in this case implies that NTA yields sustainability to local food supply chain more than monocrop system.

A Threshold Concept Perspective for Enhancing Effectiveness of PhD Supervision in Computing~ Disciplines

引用

Computer Technology and Application 2011年第3期2卷 238-246页

作者： Farhad Daneshgar raweewan Kaewwit Bootsara Prakobtham Australian School of Business University of New South Wales Sydney 2006 Australia School of Business Administration Bangkok University Bangkok 12120 Thailand

This study describes the planning process of a major multi-disciplinary research project that aims to enhance effectiveness of the Higher Degree Research （HDR） training process in computing-related disciplines by applying the threshold concept theories and framework. Two specific disciplines, the computer science and information systems were chosen for the study that closely represents the two ends of a wide range of computing discipline spectrum within the faculties of science, engineering, business and education. The ultimate goal of the above major project, when completed, is to enhance productivity of research training process in computing schools. The foreshadowed problem is that for many of HDR students it takes a long time to produce a specific result expected to be done in much shorter periods of time; and yet at some stage the student seems to get over this hurdle almost overnight. By adopting a threshold concept framework this study extends existing studies in the above area by specifically targeting HDR process in computing disciplines, and provides plans for a wide range of studies that will ideally lead to identification of threshold concept for HDR students in computing disciplines. The issue under development in the current study is how can the process of overcoming the above hurdles be facilitated？ How can the productivity of various resources utilized during the above long and frustrating waiting periods be increased by shortening the waiting times？
