http://ijaers.com/ Open Access international Journal to publish research paper en-us August The objective of all this was to evaluate the risks of using drugs in the weight loss process. This research aims to show the importance of using correct medications, prescribed by doctors in a controlled manner, in the weight loss process, encouraging the patient to use non-pharmacological methods to achieve success in weight loss. Methodology: A literature review study was carried out, using the ABNT standards, through the databases, SCIELO (Scientific Electronic Library On-line), MEDLINE, LILACS, Google Scholar, Bireme, Ebsco Host, Pubmed, books and articles published between 2011 and 2021 in Portuguese, English and Spanish, articles that met the following criteria were included: (1) studies that focus on the use of weight loss drugs and their risks (2) studies that are available in full text. Incomplete and unavailable articles were excluded from the bibliographic search. Conclusion: The indiscriminate use of weight loss drugs can cause adverse effects, such as anxiety, heart problems, confusion, insomnia, mood swings and violent behavior. In addition to these disorders, there are psychiatric disorders, including delusions, visual and auditory hallucinations, and delusions. http://ijaers.com/detail/the-risks-of-using-medication-for-weight-loss/ Clara Barros de Souza, Nathan Pedro Saraiva Oliveira, Milena Soares Corrêa, Eugênio Maria Gomes, Kaio Vieira Ramos, Paulo Pereira de Souza, Rafaela trindade Souza, Arthur Martins Freitas, Wanessa Soares Luiz Silva, Daniel Rodrigues Silva http://ijaers.com/uploads/issue_files/1IJAERS-08202310-TheRisks.pdf The purpose of the study, conducted from August 8th to 12th, 2022, in Gabon’s Lékédi National Park, was to assess elephant movement in relation to the availability of Moabi tree fruit. The goal was to understand the close connection between fluctuating temperatures and elephant movement toward human habitations. A questionnaire was utilized to gather insights from 53 individuals, primarily adults residing around Lékédi National Park. Statistical analysis of the collected data revealed a significant correlation between the percentage of individuals noticing changes in Moabi tree productivity and variations in mean annual temperature. The mean annual temperature had increased by +0.06°C over the two consecutive 5-year intervals between 2011 and 2020 (study period). The survey indicated that 56.6% of respondents perceived the Moabi fruit harvest as average in the last two years, and around 90% of people had witnessed their own or a relative’s field being devastated by elephants during the same period. Notably, 96.23% of respondents believed that present-day elephants are getting closer to human dwellings, compared to 3.77% who thought they were moving farther away. The lack of available Moabi fruit would encourage elephants to venture into secondary forests, thereby escalating the risk of human-elephant conflict. http://ijaers.com/detail/a-temperatures-variation-favor-human-elephant-conflict-in-gabon-s-l-k-di-national-park/ Djes-Frésy Bilenga Moukodouma, Donald Romarick Rotimbo Mbourou, Christiane Atteke Nkoulembene, Christophe Denis http://ijaers.com/uploads/issue_files/2IJAERS-0720236-Atemperatures.pdf One of the production processes for making weaving from doyo leaf fiber is the process of softening the dry leaf fiber before it is spun into yarn. This softening process is done so that the dried leaf fibers become more flexible and elastic so they can be easily spun into yarn. One aspect of machine design is reviewing machine design from ergonomic factors so that the machines used by workers are safer and more comfortable. This study aims to design a doyo leaf fiber softener machine in terms of the ergonomics of the machine's products. The analysis used in this study is an ergonomic analysis using anthropometric data tables using the sex of adult women, aged 18-45 years with a size of 50 percentile, from the Indonesian ethnic group. The results of the analysis show that the ergonomic machine height for workers is 100 cm, with a width of 100 cm and a machine height of 70 cm. The contribution of this research is to provide a design and build of doyo leaf fiber softener machine to the softener machine manufacturing industry so that the machine becomes ergonomic for the safety and comfort of the user. http://ijaers.com/detail/ergonomics-and-anthropometry-in-the-design-of-doyo-leaf-fiber-softener-machine/ Dwi Cahyadi, Suparno, Ratna Wulaningrum, Imam Rojiki, Ferry Bayu Setiawan http://ijaers.com/uploads/issue_files/3IJAERS-0720238-Ergonomics.pdf The present work had as a line of research "The ludic in early childhood education" as a general objective to show the work of teachers in early childhood education regarding playfulness, such as playing and developing and the activities developed in municipal schools in Porto Nacional - TO , in the morning period of the pre-school that serves students aged between four and six years old. Twenty-three teachers collaborated for the field research in three schools. This research had a qualitative approach, with a descriptive and explanatory nature. In the first moment, there were collections of data obtained based on the application of the questionnaire, and the second part was to tabulate the data, generate the graphs and obtain the results and discussion. It is concluded that the tasks developed in the classroom regarding the ludic is valued by the pedagogues, they are specific methods, activities developed in the educational space are necessary for the student's reality and for the pedagogue who is as a mediator. The analysis of the results indicates that the teachers, in turn, work with the games, but the lack of adequate spaces makes the ludic pedagogical practices unsatisfactory. http://ijaers.com/detail/playfulness-in-early-childhood-education/ Renata Dias de Freitas, Angelo Ricardo Balduino http://ijaers.com/uploads/issue_files/4IJAERS-0820231-Playfulness.pdf This work evaluated the possibility of generating electricity from flared gases through the application of combined power cycle (Organic Rankine and Brayton circle) which was simulated using Aspen Hysys. The data for the stimulation was obtained from literature in terms of the process plant operating conditions. The results obtained from the simulation were presented in terms of material balance, energy balance, costing, sensitivity analysis and exergy analysis, which is otherwise known as energy availability. The major equipment in the plants were: pump, heat exchanger, compressor, combustion chamber (conversion reactor), and an expender modeled as a gas and steam turbine respectively in Aspen Hysys simulation. The condenser was modeled as a cooler. The material and balance results were in agreement with the principles of conservation of mass and energy for a stead state process. The costing of the plant in terms of total capital cost, total operating cost, total utility cost, equipment cost and total installation cost were: $16,762,100.00, $70,661,490.00, $4,745,230.00, $11,323,700.00 and $12,359,400.00 correspondingly. The sensitivity analysis results revealed that efficiency of the gas turbine increase with an increase in exhaust gas pressure (kPa), signifying that the efficiency increased from 81.5% to 85% when the exhaust gas pressure was raised from 100 kPa to 500 kPa. The efficiency of the steam turbine increased from 72.6% to 74.2% when the outlet pressure was raised from 100 kPa to 900 kPa. Finally, the exergy result for gas turbine in terms of total exergy inlet and outlet are 14187 kW and 3710 kW respectively. This indicates an exergy efficiency of 26.15% or 10,477 kW exergy destruction. Similarly, the exergy result for steam turbine in terms of total exergy inlet and outlet are 1,856 kW and 1,357 kW respectively. This indicates an exergy efficiency of 73.12% or 498kW exergy destruction http://ijaers.com/detail/the-possibility-of-using-flared-gas-to-generate-electricity-using-combined-power-cycle/ Ubong Nsikak Ubong, Prof. Emenike Wami, Dr. E.

Ehirim, Prof Etim U Ubong http://ijaers.com/uploads/issue_files/5IJAERS-0820233-ThePossibility.pdf In this work a combination of type 2 fuzzy logic and nonsingular fast sliding mode technique is proposed to design a robust controller for a robotic system. Indeed, a nominal type 2 fuzzy model is used to contract the equivalent control signal. The switching signal is designed using adaptive type 2 fuzzy systems to overcome the knowledge of the upper bounds of uncertainties and external disturbances. Several simulation results are given to show the efficiency of the proposed approach. http://ijaers.com/detail/a-fuzzy-robust-controller-for-robotic-systems/ Lafi Alnufaie http://ijaers.com/uploads/issue_files/6IJAERS-08202312-AFuzzy.pdf
