“…Obesity poses a significant threat to health and is associated with various diseases such as coronary artery disease, hypertension, and stroke as well as respiratory disorders including sleep apnea [1][2][3]. Traditional methods for evaluating obesity, such as waist circumference and other body measurements, have limitations in providing comprehensive clinical insights.…”

This paper presents the development and evaluation of the i Series BIA (bioelectrical impedance analysis) device (models i20, i25, i30, i35, i50, i55), by MEDIANA Co., Ltd. The device utilizes a tetra-polar electrode method incorporating 8-point electrodes to improve the accuracy and reliability of body composition analysis. This paper employs a multi-frequency segmental measurement method with a wide range of measurement frequencies from 1 kHz to 1000 kHz. In comparing the correlation between Dual Energy X-ray Absorptiometry (DEXA) and BIA devices for fat-free mass (FFM) and muscle mass measurements, the results demonstrated a high correlation, with a coefficient of determination (R) of 0.984 for fat-free mass and 0.983 for muscle mass, respectively.

“…He applied the research of intelligent image sensor to real life, but the research is not comprehensive enough, and the scope of application is relatively small. Lee et al improved the performance of traditional image sensors, making it meet the requirements of high resolution and high compression ratio of images in hardware design [8]. His research has added a lot of help to the application of image sensors, but the hardware requirements are also relatively high, resulting in higher costs.…”

English cross-cultural communication is crucial in global trade, technology circulation, and cultural exchange, because not only is the difference between different cultures in language, but the knowledge requirements for cross-cultural communication are even higher. However, in the decades of English teaching development, is still difficult for the research on cross-cultural communication teaching to get rid of the test-taking mode, which makes it difficult for most people to apply it to real life after learning English. In order to solve the problem that English learning is not thorough enough in cross-cultural communication and lacks practicality, this paper starts with the selection of intelligent image sensors, based on CMOS image sensors, sets the sensor parameters and characteristics, and builds multimedia teaching equipment at the same time. Through these methods, it forms an English teaching system for cross-cultural communication and proposes classroom teaching procedures and methods. After four months of teaching experiments with this system, the educated students have made remarkable progress in cross-cultural communication. They have improved to varying degrees in four aspects: cross-cultural communication skills, mastery of cultural knowledge, accuracy of English expression, and ability to adapt to cultural situations. Among them, the accuracy of English expression improved the most in different cultures, and the average score increased by 16 points. In terms of comprehensive performance, the average level of students improved by 17% from preexperiment to postexperiment. Therefore, the teaching system in this paper can help students to have better performance in cross-cultural English communication.

“…This amount of raw image data is not suitable for sending via wireless communication and, thus, the amount of raw data must first be reduced by applying an appropriate method. A popular image compression scheme is joint photographic experts group (JPEG) compression [11,12]. JPEG is a lossy compression scheme that can convert a two-dimensional image pixel to frequency components and coefficients.…”

In this paper; a technique is proposed for reducing the energy consumption of microcontroller-based sensor nodes by switching the operating clock between low and high frequencies. The proposed concept is motivated by the fact that if the application codes of the microcontroller unit (MCU) consist of no-wait state instruction sets, it consumes less energy when it operates with a higher frequency. When the application code of the MCU consists of wait instruction sets; e.g., a wait acknowledge signal, it switches to low clock frequency. The experimental results confirm that the proposed technique can reduce the MCU energy consumption up to 66.9%.
