Social Sciences and Humanities Open 2023年第1期7卷

作者： De Sousa, Nelson Monteiro Oliveira, Clóvis Bosco Cunha, Darliane Postgraduate Program in Energy and Environment Federal University of Maranhão Brazil Electrical Engineering Department Federal University of Maranhão Brazil Department of Accounting and Administration Federal University of Maranhão Brazil

Photovoltaic (PV) energy production is a promising and mature technology for producing renewable energy. By contrast, solar panel disposals can generate problems for waste management, given that the amount of PV solar energy e-waste is more significant than other types of e-waste, given that this waste contains abundant metals and toxic materials, and given that this energy is being increasingly used. Local solutions need to be discussed and evaluated so that the PV industry can provide sustainable renewable energy. This paper discusses the environmental impacts of PV solar energy and PV panel recycling in Brazil. More efficient technological solutions and process developments will be needed to adequately treat problems arising at the end of the useful life cycle of PV systems. However, more than these technological solutions and process developments are required. Political mechanisms and regulatory structures will also need to be developed and implemented at the end of the life cycle stage to prepare, encourage, and develop appropriate industrial waste treatment applications. The advent of sector agreements for electrical and electronic equipment in Brazil has partially dealt with these waste problems. Sector agreements list equipment and devices that must have defined reverse logistics systems. © 2023 The Authors

Journal of Physics: Conference Series 2019年第1期1360卷

作者： M Limbong Postgraduate Program for Education Administration Universitas Kristen Indonesia Jakarta Indonesia

This research is conducted by thorough observation and anecdotal notes taken during the field research. The data was analysed with SWOT, resulting these points: teachers' educational background is S1/D4; the teachers are discipline; the schools are provided with sufficient facilitations and are free tuition. The identified barriers are no sufficient trainings for the teachers; the places (schools) are isolated; and lack of local government's attention. The schools have the opportunities to receive school operation fund from central government, called BOS (Bantuan Operasional Sekolah) and have internet connection provided by the company. On the other hands, there are many issues which need to be solved: teachers are lack of trainings; there's a possibility that. The school operation fund is stopped by government; some company policies which may not support school programs; and disorganized school management because students can leave before the school year ends. There are some underpin points to be done to increase the quality of teaching-learning process and school management, they are to give the teachers opportunities have external and internal trainings, and to provide facilities needed step by step.

The present work aims to demonstrate that the use of computational intelligence in judicial provision can bring speed and legal certainty to judicial decisions. The possibility of using a technological tool based on processing in natural language and textual classification will be created and then evaluated for the simultaneous application of judicial precedents. With this, it will be sought to prove that the judicial decision can be rendered more quickly. Through the use of computational intelligence, we carried out the reading of the initial petition of processes distributed with the Special Courts of the District of Palmas-Toin Brazil in the years 2019 to 2022, focusing in the binding precedents edited by the STF and ST J. We seek the possible incidence and application of the binding precedent in the specific case and thus demonstrate that the judge could know, right after the filing of the action, that the object of the inaugural claim already had a manifestation of the STF or STJ and therefore it would be up to the judgment of injunction, and thus prove the possibility of obtaining speed and legal certainty in the jurisdictional provision with the combined use of technology with binding precedents.

The Use of Hypnotics for Insomnia Disorder in Saudi Arabia: A Survey of Patients’ Experiences and Perceptions

引用

Sleep and Vigilance 2021年第2期5卷 235-244页

作者： Dobia, Ali M. Ryan, Kath M. BaHammam, Ahmed S. Abutaleb, Mohammed H. Alwadani, Rawaah Y. Edwards, Alexander D. Senior Pharmacist General Administration of Medical Services Ministry of Interior Riyadh Saudi Arabia Professor of Social Pharmacy Reading School of Pharmacy University of Reading United Kingdom Director of the University Sleep Disorders Center College of Medicine King Saud University King Saud Riyadh Saudi Arabia Consultant Clinical Pharmacist and Director of Postgraduate Clinical Pharmacy Residency Program King Fahd Central Hospital Jazan Saudi Arabia Board Member Saudi Scientific Council of Pharmacy Saudi Commission for Health Specialties Riyadh Saudi Arabia General Administration of Medical Services Ministry of Interior Riyadh Saudi Arabia Associate Professor in Biomedical Technology Reading School of Pharmacy University of Reading United Kingdom

Purpose: This study investigated the experiences and perceptions of Saudi patients with insomnia disorder. Method: A cross-sectional design study (July 2019) using a self-administered questionnaire survey. Results: Sixty-eight patients with insomnia disorder participated (53% male, 47% female;60% were younger than 45 years and a majority had a university-degree education level). Of the respondents, 64.7% were dissatisfied with their knowledge of insomnia and 97% wanted more information about its treatment. Approximately 59% used prescribed sleep medicines from the first instance and only 6% were referred to a psychologist for counselling. Benzodiazepines and Z-drugs were prescribed for 16% and 19% of respondents, respectively. A majority of respondents were given antihistamines or over-the-counter herbs. While 60% of patients used medications for long periods, 87% were not involved in treatment decisions. For those on long-term use, 80% were not seen regularly by doctors and 93% were provided with no plan for medicine discontinuations. More than 60% of respondents said that sleeping pills were best for treating insomnia and 31% believed that they are safe and would continue taking them. More than 45% would not prefer non-pharmacological treatments (e.g., counselling). Conclusions: Responses to the survey indicate a lack of knowledge about insomnia disorder and its treatment among Saudi patients. Prescribing hypnotics is the most common treatment, non-pharmacological treatments are seldom used, and responses indicated inappropriate and long-term use of hypnotics. Patients should be better educated about insomnia and its treatment. Physicians should consider using non-pharmacological treatments and the Saudi Ministry of Health should develop country-specific guidelines. © 2021, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

This research offers an alternative for health workers to monitor the rehabilitation of a patient's Range of Motion (ROM) without using a goniometer instrument and attaching various sensors to the patient's body, based on a detection system using the MediaPipe library. The developed detection system measures angles concerning the patient's body ROM patterns. The algorithm in the MediaPipe library helps to produce line graphs of landmark pose which are then processed using the trigonometric gradient equation so that it can have to measure angles from ROM. The angle of ROM measured includes Flexion-Extension and Abduction-Adduction movements of the arms, legs, and body. The results of testing the detection system between the goniometer measurements and the detection results differ from the Right Arm Elbow Flexion-Extension movement to the Trunk Flexion-Extension movement having an angle difference. The most significant angle difference is in the Right Arm Elbow Abduction - Adduction movement of 9.1388°, and the minor difference is in the Right Leg Hip Abduction - Adduction movement of 2.15°. The most significant overall system error is in the Left Arm Elbow Flexion - Extension movement, with a general system error of 27%. The minor system error in Left Arm Elbow Abduction - Adduction movement is 11 %.

Student score and responses to the analogy approach in learning physics in terms of gender and parents' work

引用

Journal of Physics: Conference Series 2021年第1期1816卷

作者： H Sahidu Susilawati M Zuhdi J Rokhmat Department of Physics Education Faculty of Teacher Training and Education Universitas Mataram Indonesia Department of Science Education Postgraduate Program Universitas Mataram Indonesia Department of Education Administration Postgraduate Program Universitas Mataram Indonesia

This study aims to identify the types of analogy approaches required in learning physics and analyze physics scores of students based on gender and parent's occupation. This research uses quantitative and qualitative approaches. Quantitative data is in the form of primary and secondary data. Primary data were collected using a questionnaire, while secondary data were from a teacher. Meanwhile, the qualitative data were collected using an open questionnaire. Quantitative analysis use using non-parametric statistics (Mann-Whitney) with the help of IBM SPSS version 24, while qualitative analysis is descriptive. The results of the study (with a significance of 0.05) showed that gender (sig.-value = 0.584 for PA and 0.874 for physical grades, greater than 0.05) and the type of work of parents (sig.-value = 0.303 for PA and 0.528 for physics scores, greater than 0.05) did not affect student responses about the analogy approach and to the students' physics scores. Meanwhile, the the open questionnaire results generally stated that the students were happy, interesting, motivated, easier, clearer, more meaningful, more understanding of concepts, effective, and efficient in learning physics. The recommendation is that this analogy approach needs to be developed on other physics concepts and implemented in physics learning.
