Agricultural export and economic growth in ASEAN countries

Thesis(Master) --KDI School:Master of Public Policy,2017Many of developing countries in ASEAN community are still depend on the agricultural environment. This research applied the fixed effect and random effects regression model to examine the impact of the primary product of agricultural export on the countries economics growth in selected developing ASEAN countries. The study period is from 1995-2014 using year dummy variables. The outcomes of the study show the primary products of agricultural raw materials export is statistically significant on the inverse relation on the growth of economic. But the manufactured export (non-agricultural export) is strongly and positively effect on the economic development. Based on main finding of this research, this study concluded that the domestically value-added processing should be encouraged instead of exporting raw material to the foreign market. Over-reliance on primary agriculture export (raw material) may suffer economic development of the country. The manufactured export should expand to rapid increase of economic development.I.

Quantum dots based superluminescent diodes and photonic crystal surface emitting lasers

This thesis reports the design, fabrication, and electrical and optical characterisations of GaAs-based quantum dot (QD) photonic devices, specifically focusing on superluminescent diodes (SLDs) and photonic crystal surface-emitting lasers (PCSELs). The integration of QD active regions in these devices is advantageous due to their characteristics such as temperature insensitivity, feedback insensitivity, and ability to utilise the ground state (GS) and excited state (ES) of the dots. In an initial study concerning the fabrication of QD-SLDs, the influence of ridge waveguide etch depth on the electrical and optical properties of the devices are investigated. It is shown that the output power and modal gain from shallow etched ridge waveguide is higher than those of deep etched waveguides. Subsequently, the thermal performance of the devices is analysed. With increased temperature over 170 ºC, the spectral bandwidth is dramatically increased by thermally excited carrier transition in excited states of the dots. Following this, an investigation of a high dot density hybrid quantum well/ quantum dot (QW/QD) active structure for broadband, high-modal gain SLDs is presented. The influence of the number of QD layers on the modal gain of hybrid QW/QD structures is analysed. It is shown that higher number of dot layer provides higher modal gain value, however, there is lack of emission from QW due to the requirement of large number of carriers to saturate the QD. Additionally, a comparison is made between “unchirped QD” and “ chirped QD” of hybrid QW/QD structure in terms of modal gain and spectral bandwidth. It is showed that “chirped” of the QD can improve the “flatness” of the spectral bandwidth. Lastly, the use of self-assembled InAs QD as the active material in epitaxially regrown GaAs-based PCSELs is explored for the first time. Initially, it is shown that both GS and ES lasing can be achieved for QD-PCSELs by changing the grating period of the photonic crystal (PC). The careful design of these grating periods allows lasing from neighbouring devices at GS ( ~1230 nm) and ES (~1140 nm), 90 nm apart in wavelength. Following this, the effect of device area, PC etch depth, PC atom shape (circle or triangle or orientation) on lasing performance is presented. It is shown that lower threshold current density and higher slope efficiencies is achieved with increasing the device size. The deeper PC height device has higher output power due to more suitable height and minimal distance to active region. The triangular atom shape has slightly higher slope efficiency compared to triangular atom shape which is attributed to breaking in-plane symmetry and increase out-of-plane emission

UCSY-SC1: A Myanmar speech corpus for automatic speech recognition

This paper introduces a speech corpus which is developed for Myanmar Automatic Speech Recognition (ASR) research. Automatic Speech Recognition (ASR) research has been conducted by the researchers around the world to improve their language technologies. Speech corpora are important in developing the ASR and the creation of the corpora is necessary especially for low-resourced languages. Myanmar language can be regarded as a low-resourced language because of lack of pre-created resources for speech processing research. In this work, a speech corpus named UCSY-SC1 (University of Computer Studies Yangon - Speech Corpus1) is created for Myanmar ASR research. The corpus consists of two types of domain: news and daily conversations. The total size of the speech corpus is over 42 hrs. There are 25 hrs of web news and 17 hrs of conversational recorded data.The corpus was collected from 177 females and 84 males for the news data and 42 females and 4 males for conversational domain. This corpus was used as training data for developing Myanmar ASR. Three different types of acoustic models  such as Gaussian Mixture Model (GMM) - Hidden Markov Model (HMM), Deep Neural Network (DNN), and Convolutional Neural Network (CNN) models were built and compared their results. Experiments were conducted on different data  sizes and evaluation is done by two test sets: TestSet1, web news and TestSet2, recorded conversational data. It showed that the performance of Myanmar ASRs using this corpus gave satisfiable results on both test sets. The Myanmar ASR  using this corpus leading to word error rates of 15.61% on TestSet1 and 24.43% on TestSet2

Seismic Risk Analysis for Critical Infrastructure: The Case Study of a Medical Center and its Supporting Systems in Yangon, Myanmar

Myanmar has a great strike-slip active fault called the “Sagaing Fault Zone” besides the Sumatra-Andaman Subduction Zone. Major cities (Yangon, Naypyitaw, Bago and Mandalay) are at risk along this fault. Recently, in 2012, Thabeikkyin earthquake with Magnitude of 6.8 caused collapse of many residential housings and ground failures near Mandalay. Therefore more attention should be paid for Yangon which has no large earthquakes since 1930 and is the largest not only in population but also in socio-economic activity. One of the most important concerns after an earthquake is to survive under any disastrous conditions. The medical care is requested not only for emergent injured people after an earthquake, but also for various types of patient and aged people from several weeks to longer periods. So medical center must be always functional before and after earthquake. For this purpose, medical buildings should be structurally resilient and also be functional for medical services by sustainable supply of electric power, water and any other delivery service which can be carried out by urban lifeline systems. This research is to investigate the structural vulnerability of hospital buildings and facilities, to assess the performance of urban lifeline systems and to check the operational capability of medical services in which surgical capability and life safety management method should be discussed. The water supply system is adopted as a typical lifeline system in Yangon in this study. One sample medical center in Yangon is adopted to carry out this analysis. Finally, the performance of medical services after the earthquakes can be assessed in a probabilistic manner

Young key affected population in Myanmar: are there any challenges in seeking information and care for HIV/sexually transmitted infections and reproductive health? [version 2; referees: 2 approved]

Background: Unmet needs and barriers in seeking HIV/STI and RH information and care are present especially among young key affected population (YKAP). Therefore, the study was conducted to determine the health seeking behaviors of YKAP regarding HIV/STI and RH, and challenges in seeking health information and care. Methods: A cross-sectional, mixed-methods study was conducted at two large cities in Myanmar. Face-to-face interviews were conducted with YKAP aged 15-24 years. In-depth interviews and key informant interviews were done with YKAP and health care providers. Descriptive statistics and bivariate analyses were done for quantitative data and thematic analysis was applied for qualitative data. Results: A total of 119 young men who have sex with men (YMSM) and 123 young female sex workers (YFSW) included in the study. Mean age of YMSM and YFSW were 20.9±2.4 and 21.7±2.2 years. Over 30% of YMSM and 49.3% of YFSW had experience of any STI symptom. Particularly, 17% of YMSM and 10% of YFSW had genital ulcer, and majority sought health care at NGO clinics. About 37% of YMSM and 40% of YFSW visited Drop-in-center (DIC) within one to six months. Over 13% of YMSM and 14.6% of YFSW had challenges in seeking HIV/STI and RH information.  YMSM/YFSW type and age of YMSM were associated with visit to DIC. Lesser proportions of Tha-nge (43.5%), younger age YMSM (66.7%), brothel-based YFSW (47.9%) visited DIC than others (p<0.05). Challenges and unmet needs expressed by YKAP were reluctance in asking health information, worry for future fertility, consequences of anal sex and contraception. Challenges expressed by providers were limited time during outreach service and difficulty in reaching entertainment-based sex workers. Conclusions: Special attention in provision of health information should be paid to YKAP since there is a considerable proportion of YKAP with unmet need in seeking HIV/STI/RH information and care

Linear Lattice and Trajectory Reconstruction and Correction at FAST Linear Accelerator

The low energy part of the FAST linear accelerator based on 1.3 GHz superconducting RF cavities was successfully commissioned. During commissioning, beam based model dependent methods were used to correct linear lattice and trajectory. Lattice correction algorithm is based on analysis of beam shape from profile monitors and trajectory responses to dipole correctors. Trajectory responses to field gradient variations in quadrupoles and phase variations in superconducting RF cavities were used to correct bunch offsets in quadrupoles and accelerating cavities relative to their magnetic axes. Details of used methods and experimental results are presented.Comment: 3 p

School and community driven dengue vector control and monitoring in Myanmar : study protocol for a cluster randomized controlled trial

DATA AVAILABILITY : No data are associated with this article.BACKGROUND : Dengue is the most common and widespread mosquito-borne arboviral disease globally estimated to cause >390 million infections and >20,000 deaths annually. There are no effective preventive drugs and the newly introduced vaccines are not yet available. Control of dengue transmission still relies primarily on mosquito vector control. Although most vector control methods currently used by national dengue control programs may temporarily reduce mosquito populations, there is little evidence that they affect transmission. There is an urgent need for innovative, participatory, effective, and locally adapted approaches for sustainable vector control and monitoring in which students can be particularly relevant contributors and to demonstrate a clear link between vector reduction and dengue transmission reduction, using tools that are inexpensive and easy to use by local communities in a sustainable manner. METHODS : Here we describe a cluster randomized controlled trial to be conducted in 46 school catchment areas in two townships in Yangon, Myanmar. The outcome measures are dengue cases confirmed by rapid diagnostic test in the townships, dengue incidence in schools, entomological indices, knowledge, attitudes and practice, behavior, and engagement. CONCLUSIONS : The trial involves middle school students that positions them to become actors in dengue knowledge transfer to their communities and take a leadership role in the delivery of vector control interventions and monitoring methods. Following this rationale, we believe that students can become change agents of decentralized vector surveillance and sustainable disease control in line with recent new paradigms in integrated and participatory vector surveillance and control. This provides an opportunity to operationalize transdisciplinary research towards sustainable health development. Due to the COVID-19 pandemic and political instability in Myanmar the project has been terminated by the donor, but the protocol will be helpful for potential future implementation of the project in Myanmar and/or elsewhere.

Factors associated with psychological distress among Myanmar residents during COVID-19 pandemic crises

Background: COVID-19 pandemic reached a public health emergency status of international concern. The impacts and events associated with this were associated with adverse psychological impacts among the general public globally. This study aimed to determine the prevalence of psychological distress and to identify predictors associated with psychological distress due to the COVID-19 pandemic among the population in Myanmar. Design and Methods: A cross-sectional survey was conducted from March to April 2020 among adults, 18 years old and above, who reside in Myanmar through a structured questionnaire distributed in social media platforms. Univariate and Bivariate analyses were used to estimate the prevalence of COVID-19 Peritraumatic Distress Index (CPDI) symptoms and to test the associations between CPDI and the exposure variables. Logistic Regression Analysis was done to identify significant predictors of distress. Results: There were 530 participants in this study.37.4% of them did not have psychological distress,55.6% experienced mild to moderate psychological distress, and 7% experienced severe psychological distress due to COVID-19 pandemic. Simple and Multiple Logistic Regression Analyses were performed to determine the factors associated with psychological distress due to COVID-19. Conclusions: It was shown that the self-employed group and age group older than 45 years old had more psychological distress than others. However, Buddhists and people from the capital city had less distress than other religions and districts. This study recommends the government to develop better strategies for self-employed groups, elders, and the poor for a support, relief, and resettlement of their ruined status

Prevalence of Depression and its Associated Factors Among Adults during Third Wave of COVID-19 Pandemic in Malaysia, 2021

Malaysia recently entered third-wave of COVID-19 pandemic starting from October 2020 to end of January 2021. Therefore, objective of our study was to identify the prevalence of depression and its associated factors among adults during third wave of COVID-19 pandemic in Malaysia. A total of 1468 Malaysian adults participated in this cross-sectional web-based survey. A standardized questionnaire was generated using the Google Form, and the link was shared through social media such as Facebook, Twitter, Instagram and WhatsApp. Patient Health Questionnaires (PHQ-9) was used to assess the levels of depression. Among 1468 participants, 320 (22 %) and 358 (24.6 %) indicated to have moderate to severe depression during third-wave of COVID-19 in Malaysia. Multiple predictors were identified that contributed to depression. These included female gender, family’s source income affected by the pandemic, do not perform exercise, victim of abuse and those with family and/or friends infected with COVID-19 virus. COVID-19 pandemic had caused the implementation of lockdown and physical distancing in Malaysia and nations across the globe. The pandemic had brought serious negative impacts on mental health of the adults especially depression especially during third wave of pandemic. The findings of our study suggested that new interventions or strategies are needed to be developed to address the severity of depression among Malaysian adults

A first absolute chronology for Late Neolithic to Early Bronze Age Myanmar: new AMS C-14 dates from Nyaung'gan and Oakaie

Late prehistoric archaeological research in Myanmar is in a phase of rapid expansion. Recent work by the Mission Archéologique Française au Myanmar aims to establish a reliable Neolithic to Iron Age culture-historical sequence, which can then be compared to surrounding regions of Southeast Asia. Excavations at Nyaung'gan and Oakaie in central Myanmar have provided 52 new AMS dates, which allow the creation of Myanmar's first reliable prehistoric radiometric chronology. They have also identified the Neolithic to Bronze Age transition in central Myanmar, which is of critical importance in understanding long-range interactions at the national, regional and inter-regional level. This research provides the first significant step towards placing late prehistoric Myanmar in its global context
