Attribute Level De-duplication Backup System for Relational Database

Efficient storage utilization is very important fortoday’s business organizations to maintain businesscontinuity and reduce the operational costs. Most ofenterprises need large amount of data to operatetheir daily transactions. Data availability andintegrity are becoming necessary for such systemsfor the extension of data retention periods in disk. So,we present the disk-based backup system in whichrelational database files are stored by using data deduplicationtechnology. Our system applies attributelevelbackup strategy in reducing the replicated dataamong records of a relation (intra-database) andalso inter-database. It reduces more redundantvalues than record-level and file-level de-duplicationand other traditional backup methods, especially instorage consumption. We only need lower space for alarge amount of files including more redundant databecause this system eliminates redundant data notonly within a file but also among different files. Ourstorage mechanism also supports to the purpose ofrecovery from accidentally damages. We use MySQLdata set of one food mart. The result depends mainlyon how much data duplication in our data set used.Our result reduces at least 25% in a little amount ofduplication and more for larger duplicated datavolume

A STUDY ON THE STRAY DOG POPULATIONS CONTROL ACTIVITIES IN YANGON REGION (CASE STUDY ON SANCHAUNG TOWNSHIP)

With the purpose to resolve the existence of stray dogs and its related public problems in Yangon, the stray dog populations control practices by key performer, YCDC and other stakeholders are studied by using descriptive method. The data and facts about different kinds of control practices such as neutering, vaccinating, sheltering, educating the public about the responsible ownership guided by the World Organization for Animal Health (OIE) and vaccination campaign program with international organizations from 2014 to 2018 updated are presented. In this study, the KII interview and the selected township household survey on Sanchaung Township are conducted to explore different perspectives and perceptions of multi-stakeholders upon stray dog existence and its control practices in Yangon Region. It is founded that poor people participation with key performers, wrong feeding practices and relatively inefficient control practices are the highest controversial rooted causes for stray dog populations controls. It can be seen that the efficiency of stray dog practices could not reach up to the welfare maximizing level but acceptable to some extent as the progressive plans are being implemented. In this study, the lack of mutual understanding, communication and weaken cooperation between public and key performers are the epidemic critical constraints of stray dog populations control practices in Yangon. All in all, it is founded that the accountability and responsibility gaps between public and key performers can only be filled with the mutual trust building and the cooperation enhancing

Evaluation of Nanofluidics Technology for High-Throughput SNP Genotyping in a Clinical Setting

The current need for high-throughput genotyping platforms for targeted validation of disease-associated single nucleotide polymorphisms (SNPs) motivated us to evaluate a novel nanofluidics platform for genotyping DNA extracted from peripheral blood and buccal wash samples. SNP genotyping was performed using a Fluidigm 48.48 Dynamic Array biochip on the BioMark polymerase chain reaction platform and results were compared against standard TaqMan assays and DNA sequencing. Pilot runs using these dynamic arrays on 90 samples against 20 SNP assays had an average call rate of 99.7%, with 100% call rates for 16 of the assays. Manual TaqMan genotyping of these samples against three SNPs demonstrated 100% correlation between the two platforms. To understand the influence of DNA template variability, three sources of blood samples (CH-1, n = 20; CH-2, n = 47; KK, n = 47) and buccal washes (n = 37) were genotyped for 24 SNPs. Although both CH-1 and CH-2 batches showed good base calling (≥98.8%), the KK batch and buccal wash samples exhibited lower call rates (82.1% and 94.0%). Importantly, repurification of the KK and buccal wash samples resulted in significant improvements in their call rates (to ≥97.9%). Scale-up for genotyping 1698 cases and controls for 24 SNPs had overall call rates of 97.6% for KK and 99.2% for CH samples. The Dynamic Array approach demonstrated accuracy similar to that of TaqMan genotyping, while offering significant savings in DNA, effort, time, and costs
