We report previously unrecognized flowering plants of Lao PDR found during a botanical survey of Lao PDR in 2015-2016. We found Phyllagathis tuberosa (C. Hansen) Cellinese & S. S. Renner (Melastomataceae) and Tolypanthus pustulatus Barlow (Loranthaceae) in the Phou Khao Khouay National Biodiversity Conservation Area (PKKNBCA), previously only known from type localities in Thailand. This is the first report of Phyllagathis tuberosa and the genus Tolypanthus in the Lao PDR. We also found Lonicera bournei Hemsl. (Caprifoliaceae) in the proposed Phosabous National Protected Area (PNPA) of Xiangkhoang, neglected with regard to the flora of Laos since its initial report in early 20th century. The current report will augment our understanding of the floristic relationships among SE Asian countries and will help elucidate the biodiversity of Lao PDR.

Background: Breast cancer is an important cause of death among women. One way of classifying different forms of breast cancer is by molecular features, usually in terms of the four subtypes: luminal A, luminal B, HER2-enriched, and triple negative. Objectives: This study aimed to investigate the association between molecular subtypes and survival among breast cancer patients treated with radiotherapy. Materials and Methods: A retrospective cohort study was conducted. The subjects were 272 breast cancer patients who had received treatment in the radiotherapy unit at Srinagarind Hospital, Thailand, between 1 January, 1999, and 31 May, 2009. The end of the study was 1 June, 2014. Overall survival was defined as the time elapsing between initial registration at the radiotherapy unit and death or the end of the study. Survival curves were estimated by the Kaplan-Meier method, and a multivariate analysis was performed using Cox's proportional hazard regression model. Results: The patient mean age was $47.5{\pm}10.4$ at the time of diagnosis. Of the 272 patients, 146 (53.7%) were classified as luminal A, 12 (4.4%) as luminal B, 30 (11.0%) as HER2-enriched, and 84 (30.9%) as triple negative. The overall survival rates at 1, 3 and 5 years were 87.1%, 68.4% and 59.2%, respectively. According to molecular subtypes, HER2-enriched patients had the lowest 5-year survival rate (30.0 %, 95%CI: 15.02-46.55). The median follow-up time was 8.37 years. In the Cox model analysis a higher risk of death was found for patients with HER2-enriched ($HR_{adj}=3.34$, 95%CI:1.96-5.67), triple negative ($HR_{adj}=2.17$, 95%CI: 1.44-3.27), and stage IIlB ($HR_{adj}=2.20$, 95%CI: 1.16-4.17) cancers. Conclusions: The worst survival rates were among patients classified as HER2-enriched, triple negative and at stage IIIB. Early detection and an advanced treatment modality are needed to help these patients.

Recently, the spatiotemporal patterns of flood disasters have become more complex and unpredictable due to climate change. Flood hazard map including information on flood risk level has been widely used as an unstructured measure against flooding damages. In order to product a high-precision flood hazard map by combination of hydrologic and hydraulic modeling, huge digital information such as topography, geology, climate, landuse and various database related to social economic are required. However, in some areas, especially in developing countries, flood hazard mapping is difficult or impossible and its accuracy is insufficient because such data is lacking or inaccessible. Therefore, this study suggests a method to delineate large scale flood-prone area based on topographic factors produced by linear binary classifier and ROC (Receiver Operation Characteristics) using globally-available geographic data such as ASTER or SRTM. We applied the proposed methodology to five different countries: North Korea Bangladesh, Indonesia, Thailand and Myanmar. The results show that model performances on flood area detection ranges from 38% (Bangladesh) to 78% (Thailand). The flood-prone area detection based on the topographical factors has a great advantage in order to easily distinguish the large-scale inundation-potent area using only digital elevation model (DEM) for ungauged watersheds.

Objective: This study was aimed to estimate the genetic parameters, including genetic and phenotypic correlations, of milk yield, lactation curve traits and milk composition of Thai dairy cattle from three government research farms. Methods: The data of 25,789 test-day milk yield and milk composition records of 1,468 cattle from lactation 1 to 3 of Holstein Friesian (HF) and crossbred HF dairy cattle calved between 1990 and 2015 from three government research farms in Thailand were analysed. 305-day milk yield was estimated by the Wood model and a test interval method. The Wood model was used for estimating cumulative 305-day milk yield, peak milk yield, days to peak milk yield and persistency. Genetic parameters were estimated using linear mixed models with herd, breed group, year and season of calving as fixed effects, and animals linked to a pedigree as random effects, together with a residual error. Univariate models were used to estimate variance components, heritability, estimated breeding values (EBVs) and repeatability of each trait, while pairwise bivariate models were used to estimate covariance components and correlations between traits in the same lactation and in the same trait across lactations. Results: The heritability of 305-day milk yield, peak milk yield and protein percentage have moderate to high estimates ranging from 0.19 to 0.45 while days to peak milk yield, persistency and fat percentage have low heritability ranging from 0.08 to 0.14 in lactation 1 cows. Further, heritability of most traits considered was higher in lactation 1 compared with lactations 2 and 3. For cows in lactation 1, high genetic correlations were found between 305-day milk yield and peak milk yield (0.86±0.07) and days to peak milk yield and persistency (0.99±0.02) while estimates of genetic correlations between the remaining traits were imprecise due to the high standard errors. The genetic correlations within the traits across lactation were high. There was no consistent trend of EBVs for most traits in the first lactation over the study period. Conclusion: Both the Wood model and test interval method can be used for milk yield estimates in these herds. However, the Wood model has advantages over the test interval method as it can be fitted using fewer test-day records and the estimated model parameters can be used to derive estimates of other lactation curve parameters. Milk yield, peak milk yield and protein percentage can be improved by a selection and mating program while days to peak milk yield, persistency and fat percentage can be improved by including into a selection index.

Background: In the years 2014, coverage rates of cervical cancer screening in Nakornnayok province accounted to 76.5%. This was lower than the government's specified goal of 80%. Community health volunteers are members of a Thai healthcare alliance established to help promoting healthcare service communication and collaboration at the primary level. Such village health volunteers (VHVs) are established in most villages. Objective: To assess the knowledge and attitudes of cervical cancer screening among VHVs. Materials and Methods: The subjects were 128 VHVs from four Nakornnayok sub-districts; namely KlongYai, Chomphol, Buangsan and Suksara, Thailand. The study was conducted from December 2014 to January 2015. The questionnaire was designed to assess the knowledge and attitude of cervical cancer screening provided by the VHVs. In addition, cervical cancer screening coverage rates of each area were collected. The demographic data, scores of knowledge, attitudes, practices and the cervical cancer screening coverage rates were analyzed by one-way ANOVA. Results: The questionnaire reliability was assessed as 0.81. The total knowledge and attitude scores were 10 and 15 points. The mean knowledge scores of KlongYai, Chomphol, Buangsan and Suksara were 6.8, 7.0, 6.5 and 9.0 points, respectively. The VHVs had a high level of overall knowledge about cervical cancer screening. The mean attitude scores were 12.4, 13.2, 13.4 and 13.1 points. VHVs had a positive attitude to the promotion of cervical cancer screening at the overall level. The percentages of VHVs promoting cervical cancer information in respective districts were 72.2, 94.3, 94.9 and 50.0. However, the cervical cancer screening coverage rates were 62.4%, 34.7%, 80.3% and 47.3% respectively. Conclusions: The knowledge, attitudes and percentages of promoting information of cervical cancer screening among VHVs in the four sub-districts were high but did not correlate with the cervical screening coverage rates for each area. VHVs needed to understand socio-cultural beliefs of the women in the target population and design suitable strategies to encourage higher cervical screening coverage.

Background: The commonly held view of the tumor suppressor p53 is as a regulator of cell proliferation, apoptosis and many other biological processes as well as external and internal stress responses. Mdm2 SNIP309 is a negative regulator of p 53. Therefore, this study aimed to determine the correlation between the patterns of Mdm2 SNIP 309 and the inflammation grading of Helicobacter pylori associated gastritis in a Thai population. Materials and Methods: A cross-sectional study was carried out from November 2014 through June 2015. Biopsy specimens were obtained from infected patients and infection was proved by positive histology. The gastric mucosa specimens were sent to the Molecular Genetic Unit, Institute of Medicine, Suranaree University of Technology where they were tested by molecular methods to detect the patterns of Mdm2 SNIP 309 using the real-time PCR hybridization probe method. The results were analyzed and compared with the Updated Sydney classification. Results: A total of 100 infected patients were interviewed and gastric mucosa specimens were collected. In this study the percentage of Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous was 78% and 19 % respectively whereas Mdm2 SNIP309 G/G homozygous was 3%. Mdm2 SNIP 309 T/T homozygous and Mdm2 SNIP309 G/T heterozygous correlated with mild to moderate inflammation (P<0.01) whereas Mdm2 SNIP309 G/G homozygous correlated with severe inflammation (P<0.01). Conclusions: Our study found the frequency of Mdm2 SNP309 G/G in our Thai population to be very low, and suggests that this can explain to some extent the low incidence of severe inflammation and gastric cancer changes in the Thai population. Mild to moderate inflammation are the most common pathologic gradings due to the unique genetic polymorphism of Mdm2 SNIP 309 in the Thai population.

This paper aims to analyze comparing the international competitiveness of Korea and China of ICT 10 goods in ASEAN Big 6 countries.(Malaysia, Indonesia, Vietnam, Singapore, Thailand, Philippines). In this study, we investigate major trends in Korea's ICT goods through various data analysis and evaluate. From 2009 to 2016, As analyzed by ESI, CTB, and EMS, This paper showed Korea has increased its export, EMS and Export Competitiveness to ASEAN. However, due to rapid imports, the trade balance deteriorated and ESI decreased. China showed signs of improvement in international competitiveness, although exports, ESI and EMS were declining. Compared to South Korea, China has seen less export bias to ASEAN. ASEAN is becoming an increasingly important trade partner in Korea's ICT exporting. This paper points out several policy implications drawn from its analyses and findings.

Opisthorchis viverrini (Ov) infection is the major etiological factor for cholangiocarcinoma (CCA), especially in northeast Thailand. We have previously reported significant involvement of PI3K/AKT/PTEN and $Wnt/{\beta}$-catenin in human CCA tissues. The present study, therefore, examined the expression and activation of PI3K/AKT/PTEN and $Wnt/{\beta}$-catenin signaling components during Ov-induced cholangiocarcinogenesis in a hamster animal model. Hamsters were divided into two groups; non-treated and Ov plus NDMA treated. The results of immunohistochemical staining showed an upregulation of PI3K/AKT signaling as determined by elevated expression of the $p85{\alpha}$-regulatory and $p110{\alpha}$-catalytic subunits of PI3K as well as increased expression and activation of AKT during cholangiocarcinogenesis. Interestingly, the staining intensity of activated AKT (p-AKT) increased in the apical regions of the bile ducts and strong staining was detected where the liver fluke resides. Moreover, PTEN, a negative regulator of PI3K/AKT, was suppressed by decreased expression and increased phosphorylation during cholangiocarcinogenesis. We also detected upregulation of $Wnt/{\beta}$-catenin signaling as determined by increased positive staining of Wnt3, Wnt3a, Wnt5a, Wnt7b and ${\beta}$-catenin, corresponded with the period of cholangiocarcinogenesis. Furthermore, nuclear staining of ${\beta}$-catenin was observed in CCA tissues. Our results suggest the liver fluke infection causes chronic inflammatory conditions which lead to upregulation of the PI3K/AKT and $Wnt/{\beta}$-catenin signaling pathways which may drive CCA carcinogenesis. These results provide useful information for drug development, prevention and treatment of CCA.

This paper describes a one of HRD Program focus on ICT technology called TOPCIT as that companies and higher education providers voiced the need for a standardized, objective competency index that can reinforce the on-site competency of college students majoring in ICT/SW. And reduce the gap between the viewpoints of industrial and academic circles regarding the qualifications of a competent specialist in ICT field. For this reason, T.OPCIT developed and evaluated a performance-evaluation-centered test designed to diagnose and assess the competency of ICT specialists and SW developers critically needed to perform jobs on the professional frontier. This TOPCIT concept has been promoted not just in KOREA but in many ASEAN countries, e.g Thailand, Nepal, Bhutan, Philippines, Mongolia and Cambodia during the ICTD-USO Forum organised by ITU-ASP.
