Chiang Rai, Thailand

Mae Fah Luang University, situated in the province of Chiang Rai in northern Thailand, is named after Her Royal Highness the Princess Mother , the mother of the current king of Thailand. Mae Fah Luang was the name given to her by the local people in Chiang Rai. It is an autonomous public university, established on September 25, 1998 and is set apart from the rest of Thailand's universities by the fact that all of its programmes are taught in English, with the exception of Thai Law and Nursing. It now has 11 schools namely, the School of Science, School of Liberal Arts, School of Management, School of Law, School of Medicine, School of Agro-Industry, School of Information Technology, School of Cosmetic Science, School of Health Science, School of Nursing and School of Anti-Ageing and Regenerative Medicine and in 2012 offers over 72 programmes such as: Biotechnology, Cosmetic Science, Engineering, Aviation Business Management, Agro-Industry, Medicine and many more. The university hospital has been completed, and was formally opened in September 2012. The School of Medicine has also been established and began offering M.D. degrees in the 2013 Academic Year.International courses offered by the university include majors in Business and Thai Language and Culture, but all courses offered by the university are open to international students.The campus is situated in Tambon Tasood, Mueang District and consists mainly of hills with only a small area of plain. Construction took many years, as the campus was mostly built on hillsides. Expansion work still continues.The university uses English as the primary medium of instruction for the majority of its courses and has a large number of native English-speaking lecturers in a wide range of disciplines. Mae Fah Luang University is a relatively new university and benefits from this by being able to offer modern courses relevant to today's world.The People's Republic of China built the Sirindhorn Chinese Language and Cultural Center on the campus as a gift to Thailand, equipping it with computers with Chinese programs and Chinese textbooks. The center is built to resemble a traditional Chinese house, complete with courtyards, gardens, and a pond. The Confucius Institute is also located here.In the 2012-2013 Academic Year over 10,000 students were enrolled at the university. Wikipedia.

Cluster ensembles have recently emerged as a powerful alternative to standard cluster analysis, aggregating several input data clusterings to generate a single output clustering, with improved robustness and stability. From the early work, these techniques held great promise; however, most of them generate the final solution based on incomplete information of a cluster ensemble. The underlying ensemble-information matrix reflects only cluster-data point relations, while those among clusters are generally overlooked. This paper presents a new link-based approach to improve the conventional matrix. It achieves this using the similarity between clusters that are estimated from a link network model of the ensemble. In particular, three new link-based algorithms are proposed for the underlying similarity assessment. The final clustering result is generated from the refined matrix using two different consensus functions of feature-based and graph-based partitioning. This approach is the first to address and explicitly employ the relationship between input partitions, which has not been emphasized by recent studies of matrix refinement. The effectiveness of the link-based approach is empirically demonstrated over 10 data sets (synthetic and real) and three benchmark evaluation measures. The results suggest the new approach is able to efficiently extract information embedded in the input clusterings, and regularly illustrate higher clustering quality in comparison to several state-of-the-art techniques. © 2011 IEEE.

Electroanalysis is one of the promising analysis methods for various aspects. Carbon nanotubes (CNTs), a novel carbon form, has been also exploited as an electrode material in electroanalysis as a result of its extraordinary electronic, chemical and mechanical properties. In addition, CNTs is also stable and robustness and is compatible with various chemical and biological species, hence the nanotubes' abilities recognized to various analyzes associated to those species. However, not only the electrode materials can influence the electrode electrochemical properties, but also the electrode orientation or architecture does. This paper, therefore, reviews various carbon nanotubes (CNTs) oriented architectures practically employed in electroanalysis for different purposes. Those include 1) CNTs casting films and CNTs polymer composites, (2) CNTs paste and polymer composites, (3) as grown CNTs and individual CNT and (4) CNTs arrays. © 2010 Published by Elsevier Ltd.

Helmets are essential for the safety of a motorcycle rider, however, the enforcement of helmet wearing is a time-consuming labour intensive task. A system for the automatic classification and tracking of motorcycle riders with and without helmets is therefore described and tested. The system uses support vector machines trained on histograms derived from head region image data of motorcycle riders using both static photographs and individual image frames from video data. The trained classifier is incorporated into a tracking system where motorcycle riders are automatically segmented from video data using background subtraction. The heads of the riders are isolated and then classified using the trained classifier. Each motorcycle rider results in a sequence of regions in adjacent time frames called tracks. These tracks are then classified as a whole using a mean of the individual classifier results. Tests show that the classifier is able to accurately classify whether riders are wearing helmets or not on static photographs. Tests on the tracking system also demonstrate the validity and usefulness of the classification approach. © 2012 The Institution of Engineering and Technology.

Background: Topical minoxidil and oral finasteride have been used to treat men with androgenetic alopecia (AGA). There are concerns about side effects of oral finasteride especially erectile dysfunction. Objective: To compare the efficacy and safety of the 24 weeks application of 3% minoxidil lotion (MNX) versus combined 3% minoxidil and 0.1% finasteride lotion (MFX) in men with AGA. Material and Method: Forty men with AGA were randomized treated with MNX or MFX. Efficacy was evaluated by hair counts and global photographic assessment. Safety assessment was performed by history and physical examination. Results: At week 24, hair counts were increased from baseline in both groups. However, paired t-test revealed statistical difference only in MFX group (p = 0.044). Unpaired t-test revealed no statistical difference between two groups with respect to change of hair counts at 24 weeks from baseline (p = 0.503). MFX showed significantly higher efficacy than MNX by global photographic assessment (p = 0.003). There was no significant difference in side effects between both groups. Conclusion: Although change of hair counts was not statistically different between two groups, global photographic assessment showed significantly greater improvement in the MFX group than the MNX group. There was no sexual side effect. MFX may be a safe and effective treatment option.

Extended producer responsibility (EPR) has become a dominant policy paradigm for the management of waste electrical and electronic equipment (WEEE) in the last two decades. In South Korea the principle has guided the evolution of the resource circulation policy even before its official introduction through a revision of the recycling law in 2002. Elements of producer responsibilities could be found in the producer-based deposit refund system (DRS) a decade earlier and they were strengthened through the enactment of a new resource circulation law in 2008. This article reviews the policy changes in South Korea for the management of WEEE during the past 20 years. The focus of the analysis is on the impacts of EPR and the producers' responses that were expressed through the quantity and the quality of material flows in the society. The findings are discussed in light of international experiences in order to outline measures to improve the effectiveness of the EPR-based resource circulation policy that could have broader implications beyond the case study. © 2013 Elsevier B.V.

Objective: To study the prevalence and risk factors of intestinal parasitic infections among hill tribe schoolchildren who attended 10 border patrol police schools in 2012, Chiang Rai, Thailand. Methods: A total of 339 subjects were recruited into the study from 2 194 children. Questionnaire was tested for validity and reliability before use. About 5 g stool specimens were collected and investigated for intestinal parasite infections by using cellophane-covered thick smear technique. Logistic regression at α = 0.05 was used to test the associations between variables to find risk factors. Results: There were 339 subjects of whom 51.9% were males and 66.1% were Buddhist; racially 31.2% were Akha and 30.4% were Kmong; mean age was 10.3 years old (minimum = 6, maximum = 16). The prevalence of parasitic infection was 9.7%. After controlling for age, sex, religion, parents' education levels and parents' occupations, the only factor that showed a statistically significant association with intestinal parasitic infection was the source of drinking water. The group of drinking mountain piped water had a greater risk of 8.22 times (adjusted odds ratio = 8.22, 95%; confidence interval: 1.07-63.18) compared to the drinking commercially bottled water group, while the group of drinking underground water had a greater risk of 9.83 times (adjusted odds ratio = 9.83, 95%; confidence interval: 0.93-104.12) compared to the drinking commercially bottled water group. Conclusions: Drinking water contaminated by soil was shown to be an important risk factor for intestinal parasitic infection in hill tribe schoolchildren living in mountainous border areas in the northern part of Thailand. Safer alternative drinking water source should be provided along with health education for schools and villagers to be aware of the risk of intestinal parasites from drinking water sources such as mountain piped or underground wells. Such sources are likely to contain higher soil contents. © 2015 Asian Pacific Tropical Medicine Press.

The volatile flavour components of different teas growing in Thailand were extracted using the simultaneous distillation and extraction (SDE) technique. These volatiles were investigated by GC-MS. At least 54 components representing 76.51-83.32% of all samples were identified. Hotrienol, geraniol and linalool were found to be the major components in Green Oolong tea. Green Assam tea contained linalool, geraniol and α-terpineol as the key flavour constituents. Chin Shin Oolong tea was dominated by linalool, indole and cis-jasmone whilst the major flavour volatiles of Chin Hsuan Oolong tea were trans-nerolidol, cis-jasmone and geraniol. Indole, geraniol and cis-jasmone were detected as the main constituents in Four Season tea. Change of quality and quantity of volatile flavour components was related to fermentation methods that increased volatiles were illustrated by the semi-fermented tea processing method. Green Assam tea infusion extract was evaluated to have the strongest antioxidant activities with the highest amount of phenol content followed by Four Season tea, Chin Shin Oolong tea, Chin Hsuan Oolong tea and Green Oolong tea, respectively. © 2010 Elsevier Ltd.

Background: A retrospective cohort study was conducted to determine the situation, trend, and factors associated with TB infection, and factors related to the life status among the HIV/AIDS Hill-tribe in Northern Thailand. Hill-tribe people have been migrating to and formed settlements along the Thai border areas for many decades. There are now having 1.6 million people of 6 different groups-Akha, Lahu, Lisu, Hmong, Yao and Keren-each with a specific culture, language and lifestyle. The Hill-tribe becomes a new vulnerable of HIV and TB infections in Thailand. Methods: A systematic data-reviewing approach was used to identify the information from the rosters of ARV clinics, OPD cards, and laboratory reports from 16 hospitals in Chiang Rai Province, Thailand. The data were collected from the first reported HIV/AIDS case of the Hill-tribe to the end of 2010. A chi-square test and logistic regression models were used to identify associations at the significance level of alpha=0.05. Results: A total of 3,130 cases were included in the study. The majority of patients were Akha (46.0%) followed by Lahu (19.7%), 54.6% were males, 44.6% were 26-35 years old. The major risk factor of HIV infection was sexual intercourse (93.1%); 23.9% were still alive at the date of data collection, 30.7% were diagnosed with pulmonary TB. The Akha Hill-tribe HIV/AIDS individuals had a greater chance of TB infection than did Yao individuals with ORadj=1.50 (95 % CI=1.01-1.92). Females had a greater chance of TB infection than males with ORadj=1.33 (95 % CI=1.11-1.59); being classified as HIV and AIDS groups had a greater chance of TB infection than those asymptomatic group with ORadj=11.59 (95 % CI=7.19-18.71), and ORadj=1.71 (95 % CI=1.03-2.87); and not having received the ARV group had a greater chance of TB infection than those who having received the ARV group with ORadj=2.59 (95% CI=2.09-3.22). The patients who had been diagnosed with HIV infection during 1990-1995 and 1996-2000 had less chance of TB infection than those who were diagnosed from 2006-2010, with ORadj=0.04 (95 % CI=0.01-0.14) and 0.11 (95 % CI=0.07-0.17), respectively. Regarding life status; females had a better chance of being still alive at the date of data collection than being males with ORadj=1.41 (95% CI=1.19-1.66). Those who had a defined route of transmission in the category of "mother-to-child" and "IDU" had a better chance of being still alive compared to those who contracted HIV from "sexual intercourse," with ORadj=2.05 (95% CI=1.56-2.18), and ORadj=8.45 (95% CI=1.55-46.13), respectively. Conclusions: Thailand needs to create a TB and HIV/AIDS surveillance system for Hill-tribe populations to determine the situation and trend and to develop an appropriate model for providing care at the earlier stage of HIV/AIDS infection to prevent later TB infection. © 2016 Apidechkul.

Background A fractional erbium-doped glass 1,550-nm and a fractional bipolar radiofrequency (RF) device are effective in the treatment of atrophic acne scars. Objective To compare the clinical effectiveness and side effects of fractional bipolar RF with those of fractional erbium-doped glass in atrophic acne scars treatment. Materials and Methods Twenty Thai subjects with atrophic acne scars received three split-face monthly treatments, one side with fractional bipolar RF and the other with fractional erbium-doped glass. Three independent physicians and patients evaluated improvement in acne scars 4 weeks after the last treatment. Side effects were also recorded after each treatment. Results The study found significant improvement in acne scars after treatment with fractional bipolar RF and with a fractional erbium-doped glass device without a statistically significant difference between the two devices. The side effects of both devices were pain, transient facial erythema, and scab formation. The pain score with fractional erbium-doped glass was higher than that with fractional bipolar RF, but duration of scab shedding was shorter. One case had postinflammatory hyperpigmentation on only the side treated with fractional erbium-doped glass. Conclusion Fractional bipolar RF and fractional erbium-doped glass have similar effectiveness for the treatment of atrophic acne scars. © 2013 by the American Society for Dermatologic Surgery, Inc.
