    Characterizing genetically distinct populations of primates is important for protecting biodiversity and effectively allocating conservation resources. Skywalker gibbons (Hoolock tianxing) were first described in 2017, with the only confirmed population consisting of 150 individuals in Mt. Gaoligong, Yunnan Province, China. Based on river geography, the distribution of the skywalker gibbon has been hypothesized to extend into Myanmar between the N’Mai Kha and Ayeyarwaddy Rivers to the west, and the Salween River (named the Thanlwin River in Myanmar and Nujiang River in China) to the east. We conducted acoustic point-count sampling surveys, collected noninvasive samples for molecular mitochondrial cytochrome b gene identification, and took photographs for morphological identification at six sites in Kachin State and three sites in Shan State to determine the presence of skywalker gibbons in predicted suitable forest areas in Myanmar. We also conducted 50 semistructured interviews with members of communities surrounding gibbon range forests to understand potential threats. In Kachin State, we audio-recorded 23 gibbon groups with group densities ranging between 0.57 and 3.6 group/km2. In Shan State, we audio-recorded 21 gibbon groups with group densities ranging between 0.134 and 1.0 group/km2. Based on genetic data obtained from skin and saliva samples, the gibbons were identified as skywalker gibbons (99.54–100% identity). Although these findings increase the species’ known population size and confirmed distribution, skywalker gibbons in Myanmar are threatened by local habitat loss, degradation, and fragmentation. Most of the skywalker gibbon population in Myanmar exists outside protected areas. Therefore, the IUCN Red List status of the skywalker gibbon should remain as Endangered

    Late prehistoric and early historic chronology of Myanmar: a four-millennia sequence from Halin

    Myanmar is located within an important geographic corridor of prehistoric demographic and technological exchange, yet relatively few archaeological sites have been securely dated. Here, the authors present a new radiocarbon chronology for Halin, a UNESCO-listed complex in the north-central Sagaing Division of Myanmar, which contributes to the generation of nuanced regional chronologies and to improving the temporal resolution of Southeast Asia more generally. Discussion of 94 radiocarbon determinates, together with site stratigraphy and pottery traditions, provides a chronological sequence from the early third millennium BC to the early second millennium AD. Corroboration of the beginning of this sequence would place Halin as the oldest currently dated Neolithic site in Mainland Southeast Asia and would provide support for the two-layer model of Neolithic migration

    The main objective of this study is to analyze the role of ICT HRD for EGovernment Initiatives in Myanmar, and the sub-objectives are to study the importance of ICT HRD for E-Government, to identify the overview of ICT HRD and E-Government implementation in Myanmar, and to examine the progress of ICT HRD for E-Government in Myanmar. Descriptive Method is used in this study. Primary data and secondary data were used for the survey analysis. The primary data was collected through an online survey questionnaire which was sent to the randomly selected 158 respondents from 14 union ministries/organizations. The survey was conducted from December, 2020 to January, 2021. The secondary data was compiled from a variety of sources include UN E-Government Survey Reports, websites, publications, and unpublished dissertations, during the period from 2000 to 2020. It is observed that the status of ICT HRD in Myanmar’s E-Government initiatives has not significantly improved, according to the analyzed data while ICT infrastructures and online services resulted in noticeable improvements. It was difficult to get more responses from the respondents who were working at rural areas with lack of internet access

    In this research work, the binding energies of light ; hypernuclei namely ; - 12C, ; - 14N and ; - 16O have been calculated within the frame work of ; single-particle model by solving nonrelativistic Schrödinger equation. In this calculation, the Gaussian basis wave function and phenomenological Woods-Saxon central potential including coulomb interaction are used. By using the strength of Woods-Saxon potential -14.0 MeV, the calculated bound state energy of ; - 14N is 3.07 MeV over binding than the recent experimental results, 4.38 r 0.25 MeV which is observed from E373 experiment, KEK, Japan. Therefore, the binding energies of ; - 14N have investigated by varying potential strength. At the potential depth -8.5 MeV, the calculated binding energy of ; - 14N is in good agreement with the experimental result. Therefore, this potential strength is applied to study the structure analysis of other two light ; hypernuclei. The observed binding energies of 1S state for ; - 12C and ; - 16O are 3.64 MeV and 5.09 MeV respectively. In addition, the root-mean-square radii of these light ; hypernuclei have also investigated. The calculated results are 3.24 fm for ; - 12C, 3.11 fm for ; - 14N and 3.02 fm for ; - 16O respectively. It is also found that 3D and 4F states are only pure ; - atomic states while the other S and P states are Coulomb-assisted nuclear ; -bound states called hybrid states

    The purpose of this research is to examine the relationship between school climate and teachers’ performance in high schools. Descriptive survey method was applied for this study. There are nine Basic Education High Schools in Pale Township. In this study, the samples were (9) principals, (236) teachers and (712) students from all Basic Education High Schools. The questionnaires were used as instruments to collect the appropriate data. There is one instrument for principals and students and two instruments for teachers. The first instrument for teachers (Q1) includes Organizational Climate Description Questionnaire (OCDQ) developed by Haplin and Croft (1963, cited in Chen, 1990). The second instrument for principals, students and teachers (Q2) is to measure teachers’ performance developed by Raza (2010) in order to obtain information for the study. In order to analyze the data obtained, Pearson-product moment correlation coefficient and descriptive statistics were computed. The result of the study indicated that the perception of the teachers on school climate was at high level. With regard to teachers’ performance, the perception of principals, students and teachers were also high level. According to ANOVA result, there was significant difference between principals, students and teachers’ perception on teachers’ performance. It was found that there was significant relationship between school climate and teachers’ performance with Pearson r of .658 at 0.001 level. The effect size of r = .658 was considered large effect size. According to simple linear regression, it can be concluded that 43% of teachers’ performance can be predicted from school climate. These results indicate that school climate is one factor that increases teachers’ performance in high schools

    This paper investigates the effectiveness of Orthogonal Frequency Division Multiplexing (OFDM) as a modulation technique for wireless radio applications. The main aim was to assess the suitability of OFDM as a modulation technique for a fixed wireless phone system for rural areas of Myanmar. The performance of OFDM was assessed by using computer simulations performed using MATLAB. Most third generation mobile phone systems are proposing to use Code Division Multiple Access (CDMA) as their modulation technique. For this reason, CDMA was also investigated so that the performance of CDMA could be compared with OFDM. OFDM was found to have total immunity to multipath delay spread provided the reflection time is less than the guard period used in the OFDM signal. The performance of the OFDM signal was found to be the same as for a single carrier system, using the same modulation technique
