Design and Development of Hybrid Maximum Power Point Tracking Algorithm for Photovoltaic Cell

Photovoltaic system (PV systems) uses solar panels to convert sunlight into electricity. Maximum Power Point Technique (MPPT) is mostly used to measure the efficiency PV system. The main objective of MPPT is to process data (Voltage and current) accumulated from the PV array and propose the proper resistance to get maximum power under any environmental conditions. In this paper we have designed and developed new algorithm for finding the Maximum Power Point of PV cell by hybridizing the usual techniques for finding the maximum power point that are “Perturb and Observe” and “Incremental conductance” to overcome their advantages and disadvantage which they have over each other. Moreover designed algorithm is developed using matlab and will be validate using real time data from the PV cell and the output will be compared with current algorithms

Competencies for Successful Middle Managers in Healthcare and Medical Education

The Kingdom of Saudi Arabia (KSA) and the Kingdom of Bahrain (KB) are currently in the process of the rapid transformation of health care to a self-sustained autonomous system. Middle managers play a pivotal role in achieving this goal. The aim of this study is to develop a feasible, reliable, and valid scale for measuring the leadership and managerial competencies of MM in KSA and KB. Zhou’s (2019) conceptual framework using a mixed-method approach was followed. After procuring ethical clearance from concerned authorities and informed consent from all the participants (n = 27), semi-structured interviews were conducted across three groups: Top Management (TM), Middle Management comprising of Middle Managers (MM), and Lower Management (LM) for the creation of items for the scale, which were later approved by five experts. Two hundred two participants from medical education (ME) and health care (HC) responded to the new scale. Cronbach\u27s alpha and exploratory and confirmatory factor analysis were performed to confirm internal consistency and validity. The model fit was adequate with a good GFI (0.90), TLI (0.96), and RMSEA (0.06). Seven major themes emerged from the thematic analysis, while a structural model with three inter-related constructs—“professionalism and problem solving,” “team management and adaptation,” and “time management and expertise” were recognized based on factor analysis. Both TM and LM identified the ability to motivate (70.8%) as comprising one of the most significant characteristics of MM. TM also indicated that concern and consideration of subordinates (68.8%) were important. LM considered being active (71.6%) as important for MM. Interestingly, MM had scored these attributes lower, illustrating the different ways in which MM is perceived across the three levels of management. Importantly, MM acknowledged concern for employee well-being, relationship, communication, and being active as crucial competencies, representing a mix of all competencies identified by the three levels of management. The “Leadership and Managerial Competency Scale for Middle Managers in Gulf Region (LMCS-MM Gulf Region)” developed under this study reflects what people in the three levels of management (lower, middle, and top) across ME and HC value in a (hypothetical) middle manager. This scale has several implications for the selection, training, and appraisal of MM in ME and HC.

A Comparison Study of Communication Skills between General Surgery and General Practice Residents on First-time Patient Visits

Background: There is little published research about differences in doctor-patient communication of different specialties. Accordingly, we compared doctor-patient communication skills in two different specialties, general surgery (GS) and general practice (GP). Methods: Twenty residents training at the Bahrain Defence Force Hospital (10 men and 10 women; mean age 28 years; 10 GS and 10 GP) participated in 200 patient first visit consultations. The consultations were video-recorded and analysed by four trained observers using the MAAS Global scale. Results: 1) Internal consistency reliability of the MAAS Global (> 0.91) and Ep2 = 0.84 for raters was high, 2) GP residents spent more time (12 minutes) than GS residents (7 minutes), in the visits, 3) There were several differences on the MAAS Global items between GP and GS residents (GS > GP, p < 0.05 on history taking, diagnosis and medical aspects; GP > GS, p < 0.05 on information giving), and 4) The present participants performed well compared to normative samples as well as to criterion-referenced cut-off scores. The general level of communication skills in both specialties, however, was ‘unsatisfactory’ and ‘doubtful’, as it is for normative samples. Conclusion: Excellent doctor-patient communication is essential but does not appear to receive the amount of attention that it deserves in practice settings. There are some differences between specialties as well as unsatisfactory communication skills for both specialties, since residents from both programs spent less time than recommended on each consultation. Our findings emphasize the need to improve the communication skills of physicians in general and for surgeons in particular.

News vs Sentiments: Impact of Monetary Policy Announcement on Developed and Developing Countries’ Market Performance

This paper investigates the impact of monetary policy announcements on the performance of the stock market in twenty countries (10 Developed and 10 developing). Exchange rate changes and changes in bond yield were taken as control. Daily basis Panel data was used with daily frequency for five (5) years (2014 – 2018).  An impact of these selected independent variables on the stock market index is estimated using the regression model and Panel Least Square model. Monetary policy data has been run in three different lags i.e. lag (0), lag (-1, -2, -3, -4), and lag (1, 2, 3, 4) in order to check the availability of monetary policy impact in pre and post announcement dates also, while the other variables run on a single lag. It is observed that the stock market of developed countries has a significant relation with monetary policy announcements, however, these announcements showed an insignificance relation with the stock market index in the case of developing countries. Moreover, exchange rates seem to have a significant effect on markets of both developing and developed countries, whereas bond yield seems to have a significant effect on the stock market of Developing countries only Keywords: monetary policy announcements, stock market index, exchange rates, bond yields, cross country, news, sentiments DOI: 10.7176/JESD/11-7-05 Publication date: April 30th 202

Measurement of Impairment among Children with Attention Deficit Hyperactivity Disorder as Part of Evaluating Treatment Outcome

Objectives: This study assesses the impairment and treatment outcome of children with attention deficit hyperactivity disorder (ADHD) in an outpatient child psychiatry clinic, using multiple sources, including the Children Global Assessment Scale (C-GAS). Methods: A total of 20 children, aged 4 to 16 years, were recruited serially in 2010 from the Child Psychiatric Unit of the Psychiatric Hospital, Manama, Bahrain. The children received a diagnosis of ADHD using the Diagnostic and Statistical Manual of Mental Disorders Text Revision (DSM-IV-TR). The children were assessed with the C-GAS by a blinded investigator, initially at the beginning of the treatment and then one year later. Results: The parents of the patients reported improvement in all cases; the improvement in impairment after one year, assessed using the C-GAS, was significant for all of the cases (P = 0.001) and low for those with comorbidity (P = 0.07). Conclusion: Measurement of improvement using the C-GAS was a suitable method of collecting data, and hence should be included in routine clinical practice for both ADHD diagnosis and outcome measurement

What leads to Employee Engagement in Pharmaceutical Sector of Pakistan?
