title: α-Glucosidase inhibitors from leaves of moringa oleifera and syzygium samarangense

description: α-Glucosidase inhibitors are effective drugs in type 2 diabetes therapy. This research aimed to investigated α-glucosidase inhibitors from two Thai medicinal plants, leaves of Moringa oleifera and Syzygium samarangense, using chromatographic technique and bioassay guidance. Isolation of methanolic extract of M. oleifera leaves yielded two flavonoids named keampferol and kaempferyl-3-O-β-glucopyranoside together with two aromatic rhamnosides named p-hydroxybenzaldehyde-O-α-L-rhamnopyranoside and 1-O-(4-hydroxymethylphenyl)-α-L-rhamnopyranoside. Of compounds isolated, keampferol exhibited the most promising inhibition (IC₅₀ 46.46 µM) against baker’s yeast α-glucosidase, which was 10 times more potent than antidiabetic drug acarbose, whereas inhibitory effect of aromatic rhamnosides was not observed. Isolation of ethylacetate extract of S. samarangense leaves yielded 13 compounds, classified into four groups: flavonols (kaempferol, quercetin, myricetin and myricitrin), flavanones (5-hydroxy-7-methoxy-6-methyl flavanone, pinostrobin, demethoxymatteucinol, 7-hydroxy-5-methoxy-6, 8-dimethyl flavanone, strobopinin and pinocembrin), chalcones (2', 4'-dihydroxy-6'-methoxy-3', 5'-dimethylchalcone and aurentiacin) and gallic acid. The results indicated flavonols showed broad and potent inhibition (IC₅₀ 3.71- 94.33 µM). More interestingly, 2', 4'-Dihydroxy-6'-methoxy-3', 5'-dimethylchalcone and strobopinin containing methyl group (s) in ring A, which are common to genus Syzygium, also displayed promising inhibition. 2', 4'-Dihydroxy-6'-methoxy-3', 5'-dimethylchalcone inhibited maltase and sucrase with IC₅₀ values of 94 and 83 µM, respectively, whereas strobopinin inhibited these enzymes which IC₅₀ values of 175 and 84 µM, respectively. 2', 4'-dihydroxy-6'-methoxy-3', 5'-dimethylchalcone inhibited maltase and sucrase by mixed-type manner: Ki = 3.92, 2.32 mM and Ki' = 18 and 6.67 mM, respectively. Strobopinin inhibited maltase and sucrase by mixed-type manner: Ki = 1.84, 1.95 mM and Ki' = 6.13 and 9.09 mM, respectively. Notably, the inhibition mechanism of 2', 4'-dihydroxy-6'-methoxy-3', 5'-dimethylchalcone and strobopinin are first reported herein.

title: The Effects of extensive reading using a learner autonomy training on reading ability and reader autonomy of Thai university students

description: This research involved the exploration of the extensive reading instruction integrated with learner autonomy training strategies framework (ERLAT), a specifically designed course to suit the Thai students’ characteristics. The main objective of this study was to investigate the students’ learner autonomy and English reading ability in an extensive reading program. The participants were 37 undergraduate students who were enrolled in the Reading Academic English course. The quantitative data were then collected through the General English Reading Ability pre- and post-test, and the Learner Autonomy Training Strategies Questionnaire. Qualitative data were obtained from Bookworm’s Diary, Teacher’s Observation Checklist, and Learner Autonomy Training Interviews. After the ten-week treatment, the test scores showed that students’ English reading ability was significantly improved (p &lt; 0.05). The findings also indicated that students frequently used the cognitive and metacognitive strategies when reading extensively and their positive attitudes toward both reading and learner autonomy also increased. Based on the study finding, it could be concluded that the ERLAT could enhance reading ability and promote learner autonomy, which would eventually enabled language learners to become more autonomous readers.

title: Bid price generation model for carriers in combinatorial transportation auction

description: In combinatorial auction for truckload transportation service procurement, we introduce the bidding strategy for carrier facing the hard valuation problem to all possible routes. The regression model uses a bid-to-cost ratio of carriers surveyed in Thailand to represent the bidding behavior in combinatorial auction. This model facilitates carrier to value the bid price for interested packages that involve with pattern of transportation service under different competitive environment. The results of analysis with hypotheses by t-test reveal significantly that a pattern of transportation service, a number of competitors, and a pre-empty backhaul to new lane distance ratio with number of competitors do impact negatively on a bid-to-cost ratio of carrier, whereas a pre-empty backhaul to new lane distance ratio does impact positively on a bid-to-cost ratio of carrier in combinatorial auction. To find optimal bid price for interested packages in the incomplete information game, the research methodology in which captures monte-carlo simulation, regression model, winder determination problem and stochastic optimization model could provide the best solution to acquire the maximum expected profit. The results present that the benefit with optimal solution of bidder is more than the average market price in the competition considerably. While in turn the results also show that shipper could potentially reduce the cost of transport service procurement with this model.

title: Infinite elastic layer under axisymmetric surface loads and influence of surface stresses

description: To present a complete solution of an infinite, rigid based elastic layer under the action of axisymmetric surface loads by taking the surface energy effects into account. The corresponding boundary value problem is formulated based on a classical theory of linear elasticity for the bulk layer and a complete Gurtin-Murdoch constitutive relation for modeling the surface energy effects. In the solution procedure, an analytical technique based on Love’s representation and Hankel integral transform is adopted to derive an explicit integral-form solution for both the displacement and stress fields. A selected numerical quadrature is subsequently applied to efficiently evaluate all involved integrals. To demonstrate the influence of surface free energy and size-dependency, an extensive parametric study is carried out. The surface energy effects show strong influence on responses at the region closed to the surface and also when a length scale of the problem is comparable to the intrinsic length of the surface. Such influences are more evident when the contribution of the residual surface tension is taken into account. Moreover, three fundamental solutions are constructed by specializing the axisymmetric surface loads to a unit normal concentrated load, a unit normal ring load and a unit tangential ring load. Such basic results constitute the essential basis for the development of boundary integral equations governing other related problems, e.g., nano-indentations.

title: The Russian agricultural reform during Vladimir Putin’s regime and the implications for Thailand

description: The paper used qualitative research, with the objectives to 1) study the evolution of the agricultural policy from the time of the Russian Empire to the Soviet Union, 2) study the agricultural reform of the Russian Federation, and 3) analyze the results of the Russian agricultural reform and the implications for Thailand. The study found that the agricultural reform of Vladimir Putin from 2000 to 2008 adjusted agricultural structure to correlate more with the market, reducing agricultural import. The reform has shown many positive developments including increased production in wheat, barley and sunflower, making Russia one of the world's major exporters of the products; support of foreign investments, budget increase, land reform, and the attempt to join the WTO. Even though the policies have been successful, Russia still depends on the import of agricultural products to satisfy domestic consumption. Russia has been Thailand's no. 1 trading partner among the CIS since 2000, despite a low level of trade. Mainly Russia imports light industrial products, such as sugar, rubber, food, canned and processed fruit. Even though Russia has reformed agriculture and been able to reduced the agricultural import level, Thai's agricultural products are of different types, creating opportunities for Thailand to find more channels in exporting to the country. Furthermore, despite the continual increase of export value to Russia, there are problems, such as logistics, lack of personnel with knowledge about Russia, and the tax and non tax system.

title: Development of insulin production in pichia pastoris GS115

description: To develope insulin MIP and HMR1423 production in yeast Pichia pastoris GS115 as host organism to express insulin. Studying the effects of the optimal temperature and N-sources that produced the highest concentration of both insulin and was detected by Indirect Competitive Enzyme-Linked Immunosorbent Assay (Indirect competitive ELISA). Insulin MIP was expressed the highest concentration at 20℃ and the concentration was 39.74 µg/ml at 84 hr whereas insulin HMR1423 was expressed the highest concentration at 30℃ and the concentration was 32.74 µg/ml at 24 hr. When the optimal N-sources for both insulin production was studied, MIP expressed the highest concentration when yeast extract and peptone was used with the concentration 42.52 µg/ml at 48 hr , while HMR1423 expressed the highest concentration when ammonium sulfate was used with the concentration was 32.74 µg/ml at 24 hr. From this research, the primary structure of proteins are slightly changed in a few amino acids, parameters in protein production in P. pastoris are significantly different. Moreover, the expression of both insulin analogs in this study found in relatively short period of time comparing to the previous studies is a benefit for further development of recombinant insulin production.

title: Access to education for children : a case study of urban refugee and asylum-seekers in Bangkok

description: Urban refugees now make up almost half of the world’s total refugee population. Formal education for the children of refugee and asylum-seeker families might often be delayed due to their situation. Barriers can arise in any country but in Thailand barriers to accessing education also include the threat of arrest and detention. The purpose of this study is to determine the key factors that limit access to education for the children of urban asylum-seekers and refugees in Bangkok. The primary findings of the study are: (i) The majority of the school aged refugees and asylum-seekers studied do have access to education; but more than half receive education far below national standards. This can only be considered informal rather than formal schooling that would be recognized as fulfilling basic education requirements. (ii) The threat of arrest and detention resulting from illegal status does disrupt access to education creating a gap in consistency, but does not completely restrict access in the long term. (iii) The current strategy to enroll urban refugee and asylum-seeker children in Thai public schools appears to be the best option given the challenges of the situation, although language barriers are encountered which causes a further gap in education. The resulting gaps combined cause substantial disruption in the education of these children.

title: Barriers to maternal and child healthcare access for asylum seekers and migrants from Myanmar in Malaysia : a case study of Selayang, Kuala Lumpur

description: This study was framed around the concept of the right to access healthcare services. Article 25, of the Universal Declaration of Human Rights 1948, states that everyone has the right to a standard of living that is adequate for their health and well-being, including medical care and necessary social services. The studies intended to describe the Myanmar migrant profile in Selayang, Kuala Lumpur, identify barriers to maternal and child healthcare (MCH) access in the population and analyse gender obstacles in health access. Research was via qualitative interviews with 15 Myanmar women, a health department personnel, a UNHCR representative and a Myanmar NGO Medical Coordinator. Maximum variation sampling of ethnic groups was used; with inclusion criteria comprising Myanmar migrant women who were pregnant or recently given birth in the past 2 years, been in Malaysia at least 6 months and experienced difficulty in accessing health services. Parameters assessed included antenatal and vaccination checkups compliance, family planning knowledge and HIV/AIDS awareness. Major barriers to MCH access comprised of fear/security issues, documentation and registration problems, cost, lack of knowledge on where and why to seek MCH services, and language barriers. Physical barriers were not a major problem. This study suggests that barriers to MCH access for Myanmar asylum seekers and migrants in Kuala Lumpur come from prior to the health service sector (security, documentation, and socio-cultural factors). This is because of the irregular status of the Myanmar migrant community affecting individual and socioeconomic outcomes in determining health decisions. System based factors such as national policy towards migrants and the need for security also may have great influence in determining healthcare access. Additionally, fear of enforcement authorities prevents effective access to services. A rights-based approach may facilitate addressing barriers in MCH access in the population.

title: Effectiveness of contraceptive used behavior encouragement model to prevent unwanted pregnancy among young unmarried migrant women in Maesot, Tak Province, Thailand

description: This research was a quasi-experimental design study, aiming to determine the effectiveness of contraceptive used behavior encouragement (CUBE) intervention to prevent unwanted pregnancy among young unmarried migrant women in Maesod, Tak province, Thailand. The intervention group and the comparison group comprised 70 cases each. The experiment was conducted from 1st September 2011 to 30th April 2012. The intervention group participated in the application of self-efficacy theory and group process (CUBE intervention). Data were collected by using a self response questionnaire and interview by trained research assistant before and after the experiment. Data analysis used the following statistic: frequency, percentage distribution, mean, standard deviation, Chi square test,Non parametric 2 independent sample tests (Mann Whitney U test) for comparison of 2 groups, Friedman test and Wilcoxon Signed-Rank Test for within group comparison. After the experiment, it was found that the score for contraceptive knowledge, contraceptive self efficacy and outcome expectations in the intervention group was statistically significant higher than before experiment and also higher than the comparison group after experiment (p-value &lt; .001). There is also significant consistent contraceptive use in the intervention group with p value &lt;0.001 after experiment. The application of CUBE intervention can promote the consistent contraceptive use behavior among unmarried Myanmar migrant women.

title: The Russian health care system

description: This descriptive research contains of objectives are 1. To analyze Russia’s health care system from the Russian Empire to the present time as well as the future plan. 2. To analyze the relationship between politics and economy which have affected the formation and policies of their health care system from each period in time of Russian history. 3. To analyze the Russians’ health status in each period of time and 4. To analyze Russian’s medical service demand in Thailand. This research has gathered information from books, documents and websites concerning the medical healthcare services in Russia since the Russian Empire, the Soviet Union, until the Russian Federation in 2011 with semi-final interview structure method to Russian who use health services in Thailand then collecting information from each period, it will be analyzed in order to interpret the relationship of politics and economy to the health care system polices. The result of research shows that at first Russians relied on traditional medicine until they started to use the modern medicine in the Russian Empire. During the Soviet Union period, the health care system was the government-supervised services so everybody could access to the same standard of services. Also, the vaccine distribution was a success to control epidemic outbreaks. After the collapse of USSR and the transformation to the Russian Federation under the liberal democratic regime, the government still kept the equal opportunity health care services for the Russian population but give opportunity to treatment from private hospitals. As for the present government, the health care services have become one of the priorities for the national policies until 2020 as the strategy is improving the organization of structure, medical facilities, as well as the budgeting. Results of interviews revealed that Russian confidence in the quality of health services and facilities under the impression the property is worth, but there are still obstacles of shortage the personnel who has skilled in Russian language and the publicity of Thailand's health care service in Russia.

title: Helping or not Helping? Why and How Trivial Packages Impact the npm Ecosystem

description: Developers often share their code snippets by packaging them and making them available to others through software packages. How much a package does and how big it is can be seen as positive or negative. Recent studies showed that many packages that exist in the npm ecosystem are trivial and may introduce high dependency overhead. Hence, one question that arises is why developers choose to publish these trivial packages. Therefore, in this paper, we perform a developer-centered study to empirically examine why developers choose to publish such trivial packages. Specifically, we ask 1) why developers publish trivial packages, 2) what they believe to be the possible negative impacts of these packages, and 3) how such negative issues can be mitigated. The survey response of 59 JavaScript developers who publish trivial npm packages showed that the main reasons for publishing these trivial packages are to provide <em>reusable components</em>, <em>testing</em> & <em>documentation</em>, and <em>separation of concerns</em>. Even the developers who publish these trivial packages admitted to having issues when they publish such packages, which include the <em>maintenance of multiple packages</em>, <em>dependency hell</em>, <em>finding the right package</em>, and the <em>increase of duplicated packages</em> in the ecosystems. Furthermore, we found that the majority of the developers suggested grouping these trivial packages to cope with the problems associated with publishing them. Then, to quantitatively investigate the impact of these trivial packages on the npm ecosystem and its users, we examine grouping these trivial packages. We found that if trivial packages that are always used together are grouped, the ecosystem can reduce the number of dependencies by approximately 13%. Our findings shed light on the impact of publishing trivial packages and show that ecosystems and developer communities need to rethink their publishing policies since it can negatively impact the developers and the entire ecosystem. The published data set contains the following: List of identified trivial npm packages. The survey questions. The developers' responses to the survey. The results of the co-usage analysis of trivial npm packages.
