Comparing the effects of acupressure at LI4 and BL32 points on intramuscular injection pain

Introduction The effectiveness of some acupressure techniques in relieving the acute pain of intramuscular injection pain has been assessed in previous studies. However, the effects of acupressure at LI4 point have still remained unknown. The aim of this study was to compare the effects of acupressure at LI4 and BL32 points on intramuscular injection pain. Methods This after-only interventional study was made on 90 women were who referred to the injection unit of the Central Emergency Department, Kashan, Iran, in 2015 for receiving an intramuscular injection of penicillin. The women were randomly allocated to three 30-person groups, namely control, LI4 acupressure, and BL32 acupressure groups. After intramuscular injection of penicillin, the level of intramuscular injection pain of all women was assessed by using a 0–10 visual analog scale. Data were analyzed through doing the Kruskal–Wallis, the Chi-square, and the Fisher's exact tests, and Spearman correlation coefficient. Results The means of pain intensity in the control, LI4 acupressure, and BL32 acupressure groups were 2.76 ± 1.75, 2.33 ± 1.80, and 1.76 ± 2.45, respectively. In other words, the mean pain intensity in the control group was significantly higher than the LI4 and BL32 acupressure groups by 0.43 and 1.0 points, respectively (p = 0.011). Except for educational status, intramuscular injection pain was not significantly correlated with the participants’ other demographic characteristics as well as injection time. Conclusion Acupressure can significantly relieve intramuscular injection pain. This simple, cost-effective, and easily applicable therapy can be used in all healthcare settings for relieving intramuscular injection pain

Relationship between attitude to career and technology course with technological and entrepreneurship attitude of high school students in district one of Tabriz

Background and Objectives: Developing a positive attitude toward the subject under study is one of the common educational goals today. Teachers as well as parents believe that the student's attitude toward the subject matter affects the student's success in school. High school students' perceptions regarding technology learning may influence their decision to study in a field at the university and work in the context of science, technology, engineering, and mathematics which are considered to be the basis of economic development in developed countries. During the past decades, there has been a growing gap between the scientific and technical skills offered by the schools and the economic demand in this area, and the number of the learners and those who have been trained in technology and science has decreased in some cases. Since the main objectives of the field of education and learning  of the work and technology curriculum in the Fundamental Document of Transformation of Education for the first  year of high school is obtaining  the merits and positive attitude towards technology and entrepreneurship, the aim of this study  is investigating the relationship between attitude toward  work and technology with technological attitude and entrepreneurship of high school students in destrict one of Tabriz in the academic year 2018-2019.   MethodS: This study was a correlational research using structural equation modeling method. Data were analyzed using least squares method. This method tests the pattern in two steps which include the measurement and structural pattern test. The measurement model examines the validity and reliability of measurement tools and research structures and tests the structural pattern of hypotheses and relationships of latent variables. The statistical population consisted of 15386 high school boys and girls in district one of Tabriz who were studying in the academic year 2018-2019. The sample was selected by proportional random sampling method (the seventh, eighth, and ninth grade) and since the original questionnaire had 40 components, 10 subjects were selected for each component and on the whole, 402 subjects were selected. Data were collected using the Liou and Kuo Technological Attitude Questionnaire (2014), Athayde Entrepreneurial Attitude Questionnaire (2009), and a researcher-made attitude to career and technology c­­­ourse Questionnaire. To test the hypotheses, structural equation analysis using Smart PLS 3 software was used. Findings: The findings showed that there was a very close relationship between career and technology course, attitude to technology and entrepreneurship. Hypotheses were significant at 0.001 level and t-statistic was significant as it was higher than 1.96. Attitude to career and technology course explains  self-efficacy of learning technology as 0.44, the value of earning technology as 0.56, strategies of learning technology  as 0.56, goal orientation of learning technology as 0.63, environmental stimulus of learning technology  as 0.64, self-regulation-triggering of learning technology as 0.54, self-Regulation Implementation of learning technology as  0.68, others’ leadership as 0.40, achievement as 0.56, personal control as 0.30, creativity as 0.42, and intuition as 0.38. Conclusion: Attitude to career and technology course explained the components of technological attitude and the components of attitude to entrepreneurship. The high significance of a positive attitude to the career and technology course lies in having a positive relationship with valuable components such as self-efficacy, learning value, strategies of learning, goal orientation, environment stimulus, creating self-regulation, leadership of others, achievement, self-control, creativity and intuition; therefore, it is recommended to prioritize this course. Knowing the attitude factors and their relationship to the subjects of courses can help teachers to improve the curriculum and the effectiveness of teaching methods so that students can be more successful in learning their lessons, academic performance, and career. ===================================================================================== COPYRIGHTS  ©2021 The author(s).

Towards battery-free machine learning and inference in underwater environments

This paper is motivated by a simple question: Can we design and build battery-free devices capable of machine learning and inference in underwater environments? An affirmative answer to this question would have significant implications for a new generation of underwater sensing and monitoring applications for environmental monitoring, scientific exploration, and climate/weather prediction. To answer this question, we explore the feasibility of bridging advances from the past decade in two fields: battery-free networking and low-power machine learning. Our exploration demonstrates that it is indeed possible to enable battery-free inference in underwater environments. We designed a device that can harvest energy from underwater sound, power up an ultra-low-power microcontroller and on-board sensor, perform local inference on sensed measurements using a lightweight Deep Neural Network, and communicate the inference result via backscatter to a receiver. We tested our prototype in an emulated marine bioacoustics application, demonstrating the potential to recognize underwater animal sounds without batteries. Through this exploration, we highlight the challenges and opportunities for making underwater battery-free inference and machine learning ubiquitous

Interference temperature measurements and spectrum occupancy evaluation in the context of cognitive radio

This paper presents a refined radio spectrum measurement platform specifically designed for spectrum occupancy surveys in the context of Cognitive radio. Cognitive radio permits the opportunistic usage of licensed bands by unlicensed users without causing harmful interference to the licensed user. In this work, a study based on the measurement of the 800 MHz to 2.4 GHz frequency band at two different locations inside Universiti Teknologi Malaysia (UTM), Johor Bahru campus, Malaysia is presented. Two Tektronix RSA306B spectrum analyzer are set up to conduct simultaneous measurements at different locations for a 24 hours period. The analysis conducted in this work is based on the real spectrum data acquired from environment in the experimental set up. Busy and idle channels were identified. The channels subject to adjacent-channel interference were also identified, and the impact of the detection threshold used to detect channel activities was also discussed. The consistency of the observed channel occupation over a range of thresholds and a sudden drop has good characteristics in determining an appropriate threshold needed in order to avoid interference
