ONTOLOGY-BASED METADATA FOR COMPUTER TERMINOLOGY

Nowadays,Information Technology is rapidly improving to provide possibilities for integration among applications using various databases. It involves retrieving and integrating information from multiple data sources. The method how to easily retrieve the information and knowledge are needed. Therefore, information retrieval system should provide advanced searching facilities to retrieve information. To organize large information repositories and access these repositories efficiently, metadata can be used. Closely related to metadata is ontology. Ontology is the key component of the Semantic Web. Ontology is used not only in semantic web but also in databases and applications that need to share domain information (specific area of knowledge). Ontology comprises as the concept, properties and restrictions on properties. This paper intends take the facilities of ontology in the building of a computer terminology.This system accepts the query as input and retrieves the relevant definition, image, etc. This system is implemented by using Java API for RDF (Resource Description Framework) called Jena package

Data Consistency and Concurrency Controlling in Air Ticket Selling in Different Sites by Using Notification- Reread Method (NRM)

In the database management systems,concurrency control is an important problem forthe simultaneous execution of transaction over ashared database can create several data integrityand consistency problem. In order to operatetransactions concurrently on a shared database, aconcurrency control algorithm must be adopted tocoordinate their activities. The concurrencycontrol of a distributed system is to ensure that theconsistency of the database. Nowadays, travellingindustry become stronger, enforcing travellingcompanies to run new branches in differentlocations.If users access a database concurrency,they may interfere with each other by attemptingto read or write the same data items. Therefore, itis important to handle the order of each branch.When a user updates some data that have beenaccessed by other users in database, or execute anundo/redo operation, data consistency willprobably be destroyed. In this system, a“Notification-Reread Method (NRM)” isintroduced to solve the problem caused byconcurrent processing

Paleogeographic Evolution of Southeast Asia: Geochemistry and Geochronology of the Katha-Gangaw Range, Northern Myanmar

The Mogok continental foreland region and Katha-Gangaw range (KGR) are located in the north-central section of the Myanmar plate, which is a component of the Eurasian plate. The origin of KGR, exposed along northern Myanmar (SE Asia), is still up for argument, despite numerous prior studies. Based on the petrography, geochemistry, and detrital zircon U-Pb geochronology of metamorphic rock samples, the current study focuses on the tectonic evolution of the KGR. The study also emphasizes the phenomenon of microcontinents rifting from the Gondwanan supercontinent and their subsequent amalgamation with Asia. Detrital zircon ages from four samples in the southern region of KGR peak at 634 Ma, 525 Ma, 290 Ma, and 248 Ma, and two samples yielded > 40% of the grains of younger than 400 Ma. Similar results were obtained from three samples (out of six) from the central region of the KGR. All of the samples from the northern part of KGR are older than 400 Ma, with the exception of MT-02A, which contains nearly all of the younger grains. These younger peaks are identical to the zircon U-Pb ages of the Indochina block, the Sibumasu block, and the Pane Chaung Formation of the Myanmar plate, as well as the Langjiexue Formation (southeastern Tibet). This similarity raises the possibility of either these units being a source region of strata in northern Myanmar or sharing a similar source. The geochemistry of metamorphic rocks samples from KGR revealed loss-on-ignition (LOI) values of 0.29–4.18 wt%, emphasizing the modest to moderate alteration. The samples are enriched in large-ion lithophile elements (LILEs), and depleted in high-field strength elements (HFSEs). All metamorphic samples are peraluminous, indicating the linkage with collisional orogenies. This result is most comparable to upper continental crustal provenance. Hence, the metamorphic rocks in KGR regions must be associated with the crustal materials

Consumption of fruits and vegetables and associations with risk factors for non-communicable diseases in the Yangon region of Myanmar: A cross-sectional study

OBJECTIVES: To explore the intake of fruits and vegetables in the Yangon region, Myanmar, and to describe associations between intake of fruits and vegetables (FV) and established risk factors for non-communicable diseases. DESIGN: 2 cross-sectional studies, using the STEPs methodology. SETTING: Urban and rural areas of the Yangon region of Myanmar. PARTICIPANTS: 1486, men and women, 25-74 years, were recruited through a multistage cluster sampling method. Institutionalised people, military personnel, Buddhist monks and nuns were not invited. Physically and mentally ill people were excluded. RESULTS: Mean intake of fruit was 0.8 (SE 0.1) and 0.6 (0.0) servings/day and of vegetables 2.2 (0.1) and 1.2 (0.1) servings/day, in urban and rural areas, respectively. Adjusted for included confounders (age, sex, location, income, education, smoking and low physical activity), men and women eating ≥2 servings of fruits and vegetables/day had lower odds than others of hypertriglyceridaemia (OR 0.72 (95% CI 0.56 to 0.94)). On average, women eating at least 2 servings of fruits and vegetables per day had cholesterol levels 0.28 mmol/L lower than the levels of other women. When only adjusted for sex and age, men eating at least 2 servings of fruits and vegetables per day had cholesterol levels 0.27 mmol/L higher than other men. CONCLUSIONS: A high intake of FV was associated with lower odds of hypertriglyceridaemia among men and women. It was also associated with cholesterol levels, negatively among women and positively among men
