111 Daw Ohnmar Win USING GRAPH DATAASE FOR EFFECTIVE VISUALIATION IN LEARNING ASIC UDDHIST VOCAULARY Graph databases have a long academic tradition. At the heart of any graph database lies an efficient representation of entities and relationships between them. All graph database models have, as their formal foundation, variations on the basic mathematical definition of a graph, for example, directed or undirected graphs, labeled or unlabeled edges and nodes, hypergraphs, and hypernodes. More recently, semantic relations have become a major theme of interest of Computational Linguistics. Semantic relations among words have captured the interest of various brands of philosophers, cognitive psychologists, linguists, early childhood and second language educators, computer scientists, literary theorists, cognitive neuroscientists, psychoanalysts - investigators from just about any field whose interests involve words, meaning or the mind. The Pi Canon is the complete scripture collection of the Theravda school. Buddhist monks and scholars studied the Pi language mainly to gain access to the Buddhist Canon and many religious works were written using the Pi language. The objective of this study is to support for new Buddhist vocabulary learner to alternative view by using graph database, Neo4j. 2018
112 Yi Mon Win COMPARATIVE ANALYSIS OF RELATIONAL AND OECT ORIENTED APPROACHES FOR GIS DATAASE Objects can be many things varying from an actual feature which can be extracted from a scene to more abstract entities which are associated with those features. There are a variety of database structures which can be used to store data about spatial features. These include RDBMS (Relational Database Management Systems), OODBMS (Object Oriented Database Management Systems) and ORDBMS (Object Relational Database Management Systems). All of these have retrieval systems based on SL (Structured uery Language) and OL (Object uery Language). The aim of this research is to compare the storage structure, retrieving data of RDBMS, ORDBMS and OODBMS storing the GIS (Geographic Information System) data of some Yangon Regions townships. This research presents a study that investigates the current scope deployment of an effective and efficient geographical information system (GIS) based approach to the representation, organization and access of these databases by Yangon Region information. 2018
113 Wint Pa Pa Kyaw MASSIVELY PARALLEL POPULATION-ASED MONTE CARLO METHODS WITH MANY-CORE PROCESSORS This research presents the utility of graphics cards to perform massively parallel simulation of advanced Monte Carlo methods. Graphics cards, containing multiple Graphics Processing Units (GPUs), are selfcontained parallel computational devices that can be housed in conventional desktop and laptop computers and can be thought of as prototypes of the next generation of many-core processors. For certain classes of populationbased Monte Carlo (MC) algorithms they offer massively parallel simulation, with the added advantage over conventional distributed multicore processors that they are cheap, easily accessible, easy to maintain, easy to code, dedicated local devices with low power consumption. On a canonical set of stochastic simulation examples including population-based Markov chain Monte Carlo (MCMC) methods and Sequential Monte Carlo (SMC) methods, speedups are found from 35 to 500 fold over conventional single-threaded computer code. These findings suggest that GPUs have the potential to facilitate the growth of statistical modelling into complex data rich domains through the availability of cheap and accessible many-core computation. 2018
114 Thet Htwe Aung THE MORPHOLOGICAL CHARACTERISTICS OF OTOLITHS OF SOME ESTUARINE FISHES IN THE MOUTH OF THANLWIN RIVER AND ITS ADACENT COASTAL AREAS Based on the external morphologies of fish, a total of 20 species of estuarine fishes selected from the mouth of Thanlwin River were identified and the sagittae otoliths were taken out from fish. The result of this study showed that otoliths of pelagic fishes compared with otoliths of demersal fishes are smaller and thinner. Furthermore otoliths of different species can have similarities in appearance but they have enough differences to be distinguished from each other. In this study, different shapes of otoliths are recorded in the fishes caught from the river mouth area of Thanlwin. These included elliptic, square, discoid, rectangle, lanceolate, triangle, pistalform and spindle shapes. 2018
115 Soe Myint Aye LEAF ARCHITECTURAL STUDY ON SOME MEMERS OF CONVOLVULACEAE IN MANDALAY AND PYIN OO LWIN AREA Leaf architectural characteristics of the Family Convolvulaceae in Mandalay and Pyin oo lwin area were collected and studied during the year 2016 – 2017 . According to the identification 21 species of 7 genera were recorded in study area. The resulting species were one species of Evolvulus, Jacquemontia, Operculina and Porana, two species of Argyreia, five species of Merremia and ten species of Ipomoea. The leaves samples were decolorized by Method of Mishra et al. (2010) in Department of Botany, University of Mandalay. The qualitative features and the venation pattern of cleared leaves samples were characterized. It was found that the leaves were variously observed in shape, base, apex and margin. The margins were entire or 3-lobed. The primary veins were stout or massive and predominant tertiary vein angles were Right Right (RR), Acute Obtuse (AO), Obtuse Acute (OA), Right Obtuse (RO), Acute Right (AR), Right Acute (RA), or Acute Acute (AA). The marginal ultimate venations were looped, incomplete, or fimbriate. The primary vein categories are pinnate, actinodromous basal and actinodromous suprabasal. The secondary vein categories were brochidodromous, weak brochidodromous, cladodromous, weak cladodromous and actinodromous. Stoma types were anisocytic, anomocytic and paracytic. According to the quantitative characteristics, leaf areas were found to be variously between 40 mm2 and 460 mm2. The smallest leaf area was observed in Evolvulus nummularis (L.) L. and the largest one was in Argyreia laxiflora (Prain) Prain. The number of secondary veins along one side was variously observed between 4 and 13. The angle between primary and secondary vein, number of areoles per mm2, veinlets entering areoles per mm2, and highest vein order were different among the species. According to the different qualitative and quantitative characteristics, the leaf arichitecture provides valuable data for practical identification on members of Convolvulaceae. 2018
116 Taik Paing STUDY ON ANTIFUNGAL ACTIVITY OF ENDOPHYTIC FUNGI ON PATHOGENIC FUNGI FROM SUNFLOWER SEEDS AND IDENTIFICATION OF SELECTED ENDOPHYTIC AND PATHOGENIC FUNGI In the isolation of endophytic fungi, 5 different plant sources were collected in Pathein Area and10 kinds of endophytic fungi (TP-01,02,03,04,05,06,07,08,09,10) were isolated. For the antifungal activities, the pathogenic fungi were isolated from the seeds of sunflower grown in Hinthada Area. Three kinds of pathogenic fungi ( PF-01,PF-02,PF-03 ) were isolated by serial dilution methods. Ten kinds of isolated endophytic fungi were tested for antifungal activities. Among them, 4 kinds of endophytic fungi (TP-01,08,09,10 ) showed the antifungal activities (15 mm, 14 mm, 17 mm and 21 mm of inhibitory zones) on pathogenic fungus ( PF-03 ) of sunflower seeds. According to these inhibitory zones, the biggest zone (21 mm) of endophytic fungus from Polygonum barbatum L. (suzat-pan) belonging to the family of Polygonaceae was selected for further investigation. Selected endophytic fungus ( TP-10 ) and pathogenic fungus ( PF-03 ) were identified by using reference keys. These selected fungus were important for all farmers because the seed-borne fungi were deterioration in sunflower oil and lost yield. . 2018
