AbstractNature inspired swarm based meta-heuristic optimization technique is getting considerable attention and established to be very competitive with evolution based and physical based algorithms. This paper proposes a novel Buyer Inspired Meta-heuristic optimization Algorithm (BIMA) inspired form the social behaviour of human being in searching and bargaining for products. In BIMA, exploration and exploitation are achieved through shop to shop hoping and bargaining for products to be purchased based on cost, quality of the product, choice and distance to the shop. Comprehensive simulations are performed on 23 standard mathematical and CEC2017 benchmark functions and 3 engineering problems. An exhaustive comparative analysis with other algorithms is done by performing 30 independent runs and comparing the mean, standard deviation as well as by performing statistical test. The results showed significant improvement in terms of optimum value, convergence speed, and is also statistically more significant in comparison to most of the reported popular algorithms.

The anthropometric reference data used to examine the growth pattern of children in Spain are obtained from studies carried out several years ago. In the region of Extremadura, the tables obtained by the Faustino Obergozo Foundation, which date back to 2004, are used. The first objective of this work is to develop growth tables and graphs that accurately reflect the somatometric variables of children in Extremadura. Secondly, the averages of these variables by sex will be compared to determine if there are significant differences between them. A database provided by the General Directorate of Planning, Training, and Health and Social Quality of the Regional Government of Extremadura was used, which contains the measurements of height, weight, and body mass index (BMI) of boys and girls in Extremadura between the years 2006–2016. The database was analyzed using the Statistical Package for the Social Sciences (SPSS) version 23 and the R software version 3.5.1, considering a cross-sectional study. As a result, the tables and growth graphs of Extremadura’s population base for weight and height are presented, from birth to 10 years, as well as comparisons of the average values of the analyzed variables between boys and girls. We found that there are significant differences in the mean values, according to sex, of the height and weight. On the other hand, BMI progressed normally when comparing the results of the Extremadura population with those reflected by the World Health Organization (WHO). Differences were found when comparing the results with those obtained by the Faustino Orbegozo Foundation.

Diabetic erectile dysfunction (DED) is one of the most frequently occurring complications of diabetes mellitus (DM) in men, and past studies have usually overlooked the effect DED has on quality of life (QoL). The objectives of this study are to determine the prevalence of DED and to investigate QoL, and the factors that influence QoL, in Thai men who are living with DED. Five hundred and eighty-two Thai men living with diabetes who enrolled in the diabetic and general medical outpatient clinic at a tertiary hospital in the northern part of Thailand were surveyed to determine the prevalence of DED, as well as QoL and its influencing factors, for men living with DED. The average age of the men was 58.2 years old (±SD = 10.1, range = 34.3 - 80 years old). DED was found in 417 out of the 582 men (71.5 %). The International Index of Erectile Function (IIEF-5) mean score was 17.03 (±SD = 3.47). The QoL was found to be at a moderate level (= 95.42 ±SD = 11.39). The QoL domains found to be at a good level were the psychological (= 23.84 ±SD = 3.42) and environmental domains (= 31.4 ±SD = 3.98), while domains found to be at a moderate level were the social relationships (= 10.77 ±SD = 1.93) and physical domains (= 24.9 ±SD = 3.13). The mean score of the QoL of men living with DED was lower than that of men without DED. The most important factor associated with poor QoL was severity of DED, while men who have a good QoL tend to have a higher education level and more frequent sexual intercourse (p < 0.05). The study showed that the prevalence of erectile dysfunction in Thai men living with DED was high. DED has a moderate impact on QoL, especially on the social relationship domain. The results suggest the importance of screening for DED in clinical settings for early detection of, and creating supportive strategies for treating men with, diabetes mellitus.

The Impact

Background: The presence of cancer has a profound psychological impact on the quality of life of patients and their families, on family and social relationships, and on role functioning. Aim of the study: Assess the impact of childhood cancer on patients and their families. Subjects and methods: A Prospective questionnaire-based study, for 151 patients, had malignancy identified by tumor registry of Children Welfare Teaching Hospital. The information was taken from the parent(s) in the presence of the patient who sometimes answered some questions during the interview. Result: There was an interview with 151 families of children with cancer in the outpatient clinic. Sixty-two (41%) patients have leukemia while 89 (59%) have solid tumors. Boys were more than girls. Regarding patients, the mean age at the time of the interview was 10.2 years, while the mean age at diagnosis was 7.1 years. The majority of the parents accepted the diagnosis (89.4%), the rest of the parents (10.6%) were skeptical and tried to re-evaluate the condition elsewhere. More than one-half of the parents started to have quick temper (54%) after diagnosis. Most of them had sleep difficulties (83.2%) after diagnosis. Neglection of other siblings in the family was reported in more than one-half of the interviewed families (52.1%). Most of the parents lost their emotional control (69.2%) with the surrounding people after knowing the diagnosis. After an initial period of treatment, there was a decrease in the social activity of the families in 42% of cases. There was a high concern of the parents about the patient’s future marriage (69%), conception (62%), and career (52%). Conclusions: The establishment of a multidisciplinary cancer care team including social workers, teachers, psychologists, and others to support the child and family is seems to be mandatory during the whole period of treatment and thereafter.

This paper proposes a novel hybrid arithmetic–trigonometric optimization algorithm (ATOA) using different trigonometric functions for complex and continuously evolving real-time problems. The proposed algorithm adopts different trigonometric functions, namely sin, cos, and tan, with the conventional sine cosine algorithm (SCA) and arithmetic optimization algorithm (AOA) to improve the convergence rate and optimal search area in the exploration and exploitation phases. The proposed algorithm is simulated with 33 distinct optimization test problems consisting of multiple dimensions to showcase the effectiveness of ATOA. Furthermore, the different variants of the ATOA optimization technique are used to obtain the controller parameters for the real-time pressure process plant to investigate its performance. The obtained results have shown a remarkable performance improvement compared with the existing algorithms.

Modern Approach

Economic load dispatch plays an important role of power system operation & control by using different soft techniques that have been used to solve convex and non-convex economic load dispatch (ELD) problems. This paper presents a new global optimization algorithm to the economic load dispatch problems for minimization of fuel cost of generations with different constraints such as ramp rate limits, valve-point loading and prohibited operating zones of large-scale thermal plants. Power transmission loss has also been considered in few cases. Group leader optimization algorithm (GLOA) is a relatively new optimization technique. Mathematical models of this algorithm demonstrate the efficiency, quality of solution and convergence speed of the method and successful application of the algorithm on ELD problems. Simulation results found that the proposed approach outperforms several other existing optimization techniques in terms quality of solution obtained and computational efficiency. Results also be confirmed the robustness of the proposed methodology.

Observance of patients' rights is a significant indicator in evaluating the quality of healthcare services. The COVID-19 pandemic has become a global crisis and affected the interactions between healthcare providers and patients. This study examined the COVID-19 patients’ viewpoint about the observance of their rights by physicians and nurses. This study is a descriptive cross-sectional work of research conducted on the COVID-19 patients in Zanjan Province, Iran, in September 2020. The subjects were selected through convenience sampling, and data was collected using a two-section questionnaire consisting of a demographic characteristics survey and a Likert-type scale for evaluating patients' rights observance. The validity and reliability of the questionnaire were found to be acceptable, and the collected data was analyzed in SPSS v.26 using descriptive statistics, independent t-test, and ANOVA test. The mean score of observance of patients' rights was 69.60±7.36, representing a moderate level. The highest and lowest scores for the observance of patients' rights were related to the dimensions of courteous communication and responsibility, respectively. A significant relationship was found between the observance of patients’ rights and their marital status, health insurance, and education level (P<0.05). This study showed that the observance of the COVID-19 patients' rights has not been affected by the social agitation caused by this disease.
