Reliability Improvement of System Reconfiguration by Considering the Time-varying Load with Optimal Scheduling of Distributed Generations

The distributed generation (DG) locations have significant impacts on network configuration and loss. By fixing DGs in suitable optimal locations and by generation power based on the load conditions, the total power loss in the system can be reduced and the system reliability can be improved. Distribution system reliability assessment is able to predict the interruption profile of a distribution system based on system topology and component reliability data. In this paper, Fuzzy algorithm is used to obtain the optimum position and size of DG units in the distribution network in order to reduce network loss at the lowest cost. Also, a time-varying load curve for optimal scheduling of DGs considering active power loss and DG cost is used. The result shows the improvement of bus voltage profile and decrease losses due to install the optimal size of DGs by optimal scheduling of distributed generations. The test system is Yangon 66kv; 45-bus and the results obtained reveal the effectiveness of proposed method

Standardization of Mandalay Personality Type Survey

This study is an attempt to standardize Mandalay Personality Type Survey (MPTS). This scale is an attempt to measure personality, to assess three broad personality dimensions. These dimensions are (1) anti-social type (2) neuroticism and (3) pro-social type. The MPTS contains 180 items, which can be answered in Yes or No form. This scale was constructed by Dr.Htun Than & et al(2005). The reliability of the MPTS is .68 for anti-social, .71 for the neuroticism and .80 for pro-social. The validity of the MPTS is .31 for anti-social, .54 for the neuroticism and .62 for pro-social. The reliability and validity of MPTS is found to be satisfactory. Objectivity is one of the characteristics of a good test. For a test to be objective, it is necessary to assist the reliability, validity of the test and standardize it. By standardizing the test, it can interpret the test results or scores. Thus, the present study is fulfilled this requirement. In this study, „ T score ‟ was used as norms for MPTS. „T scores‟ equivalents for raw scores were presented in table (2). The T scores were classified into five levels. Although there are few limitations in the population sampling for pro-social personality scale, these norms can interpret an evaluation of his or her status in reference to other person. Therefore, these norms can be used for practical purpose in personnel selection

Detection of Class 1 Integron Among Klebsiella Species Isolated from Clinical Samples at No (1) Defence Services General Hospital (1000 Bedded)

Klebsiella species is commonly associated with serious nosocomial infections. Multi-drug resistant Klebsiella species isolates are becoming increasingly prevalent in the clinical and nosocomial environments. The high prevalence of Klebsiella infections is related to the ability of Klebsiella species to acquire and disseminate exogenous genes associated with mobile elements, such as plasmids, transposons and integrons. This study was conducted to find out the presence of class 1 integron and antibiotic susceptibility patterns of Klebsiella species from clinical specimens at No (1) Defence Services General Hospital (1000-Bedded). A laboratory based cross-sectional descriptive study was carried out from January to september, 2020. Identification and antimicrobial susceptibility testing of Klebsiella species was performed by VITEK 2 Compact Analyzer. Class 1 integrons were detected by conventional PCR. In this study, 110 Klebsiella species were isolated from various clinical specimens and most of the isolates were from medical ward (52.3%, 63 isolates). The highest rate of resistance was observed for ampicillin (100%) and Cefotaxime (97.3 %) whereas the lowest antibiotic resistance was to Amikacin (15.5%). Out of 110 Klebsiella isolates, 107 (97.3%) were multidrug resistant (MDR). Forty-four (40%) out of 110 Klebsiella isolates carried int1 gene and all these isolates were MDR. However, there was no association between multidrug resistance and integron positivity (p value = 0.273). The presence of class I integron genes among Klebsiella species highlights the continued monitoring is necessary for prevention of wide dissemination of integrons and infections by MDR pathogens
