Healthcare waste management at primary health centres in Mon State, Myanmar: the comparisons between hospital and non-hospital type primary health centres
No full text2019-02Improper healthcare waste management (HCWM) poses a serious public health problem worldwide. Primary health centres (PHCs) provide public health and medical care services as the basic structural and functional units of healthcare services in Myanmar. However, no study has been conducted in Myanmar about HCWM at PHCs. This study aims to assess the practice of HCWM at PHCs in Mon State, Myanmar. A cross-sectional study was conducted in all ten townships in Mon State, Myanmar. In total, 93 PHCs (71 non-hospitals and 22 hospitals) were selected using simple random sampling. The observational checklist which was developed based on the World Health Organization’s standard guideline procedure of HCWM was used to determine the practice of HCWM at PHCs. Binary logistic regression was used for final data analysis. The burning in pits method was used as the final disposal method of healthcare waste in 78.5% of PHCs. Non-hospital type PHC were more likely not to have colour coding system for HCWM (odds ratio [OR] 7.54; 95% confidence interval [CI] 2.15–26.52), did not have equipment for accidental spillage of healthcare waste (OR 3.92; 95% CI 1.3–11.77) and did not have separate staff for HCWM (OR 8.27; 95% CI 2.77–24.64), relative to hospitals. Non-hospital type PHCs practices poorly on the colour coding for waste segregation, assigning separate staff for HCWM, and possessing equipment for accidental spillage of healthcare waste than hospital type PHCs. The Ministry of Health and Sports should issue technical guidelines of safe HCWM as a compulsory policy for both hospitals and non-hospital type PHCs.departmental bulletin pape

Data Consistency of Distributed Transaction for Order Management
No full textThe general elements of transaction processing are data capture and validation, transaction-dependent processing steps and database maintenance. Database Management Systems (DBMS) are among the most complicated applications. While DBMS maintains all information in the database, applications can access this information through statements made in Structured Query Language (SQL), a language for specifying high-level operations. This paper intends to build a distributed transaction management system for store ordering with recovery control to guarantee the consistency of database. When the server crashes or connection fails, the uncommitted transaction is saved at the client store as the recoverable objects and will undo at the next time for database consistency
Graph-based Household Matching for Linking Census Data
No full textHistorical censuses consist of individual facts about a community. It provides knowledge concerned with the nation’s population. These data apply the reconstruction features of a specific period to trace their ancestors and families changes over time. Linking census data is a difficult task as common names, data quality and household changes over time. During the decades, a household may split multiple households due to marriage or move to another household. This paper proposes a graph-based approach to link households, which takes the relationship between household members. Using individual record linking results, the proposed method builds household graphs, so that the matches are determined by attribute similarity and records relationship similarity. According to the experimental results, the proposed method reaches an F-score of 0.974on Ireland Census data, outperforming all alternative methods being compared
International Journal of Electronics and Computer Science Engineering 101 Available Online at www.ijecse.org ISSN- 2277-1956 Speech De-noising and Compression using Wavelet Transform
No full textAbstract- Speech compression is an area of digital processing that is focusing on reducing bit rate of the speech signal for transmission or storage without significant loss of quality. The focus of this paper is to compress the digital speech using wavelet transform. The uncompressed digital speech requires huge amount of memory. The main idea behind the speech compression algorithm is to represent this uncompressed speech with minimum number of bits and optimum speech quality. Wavelet transform has been recently proposed for signal analysis. The wavelet transform is useful to remove redundancies and irrelevancies present in the speech signal for the compact representation. The classical subband coding method also known as filter bank method is used in which signal is decomposed into basis of wavelet functions using high pass and low pass filters. Speech coding is a lossy scheme and is implemented here to compress one-dimensional speech signal. Basically, this scheme consists of three operations which are the transform, threshold techniques (by level and global threshold), and run-length encoding operations. Finally the compressed signal is reconstructed. The speech compression using filter bank method is implemented and simulated by using wavele

Network Reconfiguration for Loss Reduction and Voltage Profile Improvement of 110-Bus Radial Distribution System Using Exhaustive Search Techniques
No full textNowadays, the electricity demand is increasing day by day and hence it is very important not only to extract electrical energy from all possible new power resources but also to reduce power losses to an acceptable minimum level in the existing distribution networks where a large amount of power dissipation occurred. In Myanmar, a lot of power is remarkably dissipated in distribution system. Among methods in reducing power losses, network reconfiguration method is employed for loss minimization and exhaustive technique is also applied to achieve the minimal loss switching scheme. Network reconfiguration in distribution systems is performed by opening sectionalizing switches and closing tie switches of the network for loss reduction and voltage profile improvement. The distribution network for existing and reconfiguration conditions are modelled and simulated by Electrical Transient Analyzer Program (ETAP) 7.5 version software. The inputs are given based on the real time data collected from 33/11kV substations under Yangon Electricity Supply Board (YESB). The proposed method is tested on 110-Bus, overhead AC radial distribution network of Dagon Seikkan Township since it is long-length, overloaded lines and high level of power dissipation is occurred in this system. According to simulation results of load flow analysis, voltage profile enhancement and power loss reduction for proposed system are revealed in this paper
