Prevalence and correlates of parkinson’s disease among elderly patients attending Neurology Clinic at Serdang Hospital in 2016

Introduction Parkinson’s disease (PD) is the second most common neurodegenerative disease after Alzheimer’s disease (AD) and the most frequent sub-cortical degenerative disease, characterized by universal progressive disorder of the nervous system that affects movement. This cross sectional study aimed to determine the prevalence and correlates of PD among elderly attending the neurology clinic in Serdang Hospital. Methods A total of 150 records of patients attended the clinic from January to December 2016 were randomly selected. Data was collected using a proforma form seeking information related to age, gender, race, locality, and presence of comorbidity particularly diabetes mellitus. The data was analysed using the Statistical Package for Social Science (IBM SPSS) version 22.0. Results The prevalence of PD among the elderly involved in the study was 34%. Majority of the respondents were aged 60 to 70 years old (54.7%), male (53.3%), Chinese (56.7%), from urban locality (93.0%) and were not diabetic (69.3%). The inferential statistics showed no significant association between all the factors with PD. However, the associations between age and diabetes mellitus with PD were almost significant with p values of 0.07 and 0.08 respectively. Conclusions Overall, the prevalence of PD among elderly who attended the neurology clinic in year 2016 was less than half with none of the factors under study were significantly associated with PD. However with bigger sample size, possible significant association may be obtained between age and diabetes mellitus

An?lisis del impacto de la acci?n siete del plan de acci?n BEPS de la OCDE en el concepto de establecimiento permanente en la legislaci?n peruana

Las empresas, para obtener mayores utilidades netas, buscan reducir su carga impositiva y utilizan estructuras corporativas generando la erosi?n de la base imponible y el traslado de beneficios fuera del pa?s de la fuente. En respuesta a ello, la Organizaci?n para la Cooperaci?n y el Desarrollo Econ?mico (OCDE), cre? el Proyecto BEPS (Base erosion and profit shifting), el mismo que consta de 15 acciones. La Acci?n 7, tiene como objetivo impedir la elusi?n artificiosa del estatuto de Establecimiento Permanente. Para el Per? este Proyecto es importante porque tiene un v?nculo con la OCDE desde el a?o 2014, con la firma del ?Programa Pa?s?. Este trabajo de investigaci?n, expone el posible impacto de las recomendaciones dadas por la OCDE mediante la Acci?n 7 del Plan BEPS en el concepto de Establecimiento Permanente en la legislaci?n de Per?. Primero, se analiza la propuesta general planteada por la OCDE mediante su Proyecto BEPS y la Acci?n Siete del Plan BEPS, con casos internacionales. Luego, analiza los alcances de la figura del Establecimiento Permanente recogida en la Ley del Impuesto a la Renta y su Reglamento. Finalmente, se expone la problem?tica de la actual regulaci?n de Establecimiento Permanente en el Per? y conclusiones

Emotional Intelligence Skills: Is Nurses' Stress and Professional Competence Related to their Emotional Intelligence Training? A quasi experimental study

Introduction: Emotional intelligence is a social skill that controls stress and affects one's ability to cope with the demands and environmental pressures; it so can improve professional competence in health care providers such as nursing students. Training on emotional intelligence increases the mental health and influences the mutual relationships, stress, depression and aggression. This study aimed to determine the effect of emotional intelligence skills training program on the stress and academic success of nursing students in a higher education health complex. Methods: This study is a quasi-experimental study with an educational intervention. The participants included 100 students of nursing selected by stratified random sampling from both genders. They were randomly categorized into two intervention and control groups including 50 subjects, respectively. We used Meyer and Salvia model in Emotional Intelligence training in the intervention group. During the training sessions in the intervention group, the control group did not receive any intervention. Academic stress and professional competence in both groups were measured before and two weeks after the experiment. SPSS version 21 was used to analyze the data, using Paired t-test, independent t-test, Wilcoxon, Mann-Whitney and Chi-Square tests. Results: The mean age of the participants was 20 +/- 2.14 years old. According to the results, the mean difference of the changes in the professional competence (P<0.001), total academic stress (P<0.001), and the four areas of academic stress such as emotional response (P<0.001), physical response (P<0.001) and physiological response (p<0.001) were significant. The intervention group, as compared with the control group, showed no significant effect on the other factors of academic stress such as frustration, conflict, academic pressure, changes and self-imposed stress. Conclusion: The education of emotional intelligence components can improve the efficiency of nursing care services and professional competence due to deceased stress

Comparison between the use of uniform and non-uniform light absorption profiles in modelling organic photovoltaics

Abstract To avoid complexity, a uniform light absorption profile is usually used when modelling organic photovoltaic cells (OPVs). However, the actual light absorption profile is not uniform. It is found that a uniform light absorption profile can be used as a replacement for the actual non-uniform light absorption profile in modelling an OPV provided that the actual light absorption profile inside the OPV has a peak absorption value that is roughly less than twice its average absorption value. Nevertheless, the use of a uniform light absorption profile in investigating the effect of a certain parameter (e.g. the active layer thickness) on the performance of OPVs should still be used with care if variations in the value of the said parameter lead to different light absorption profiles.</jats:p

An improved model for describing the net carrier recombination rate in semiconductor devices

Carrier recombination is a process that significantly influences the performance of semiconductor devices such as solar cells, photodiodes, and light-emitting diodes (LEDs). Therefore, a model that can accurately describe and quantify the net carrier recombination rate in semiconductor devices is important in order to further improve the performance of relevant semiconductor devices. The conventional model for describing the net carrier recombination rate is derived based on the condition that there is no electric current in the considered semiconductor, which is true only when the semiconductor is not part of a device, and hence, is not connected to an external circuit. The conventional model is adopted and used for describing the net carrier recombination rate in semiconductors that are part of devices (i.e., in semiconductor devices). In this paper, we derive and propose a new model for describing the net carrier recombination rate in semiconductor devices. The newly proposed model is an improvement to the currently used model by considering the fact that electric currents can flow in the semiconducting materials of semiconductor devices. We employ organic solar cells (OSCs) to validate the proposed recombination model and show that the proposed model can be crucial for modeling OSCs. Since the proposed recombination model is derived for general semiconductor devices, we expect that the use of the proposed model can also be crucial for modeling and analyzing the performance of other semiconductor devices, particularly optoelectronic devices such as LEDs and perovskite solar cells
