Optimal locations and computational frameworks of FSR and IMU sensors for measuring gait abnormalities

Neuromuscular diseases cause abnormal joint movements and drastically alter gait patterns in patients. The analysis of abnormal gait patterns can provide clinicians with an in-depth insight into implementing appropriate rehabilitation therapies. Wearable sensors are used to measure the gait patterns of neuromuscular patients due to their non-invasive and cost-efficient characteristics. FSR and IMU sensors are the most popular and efficient options. When assessing abnormal gait patterns, it is important to determine the optimal locations of FSRs and IMUs on the human body, along with their computational framework. The gait abnormalities of different types and the gait analysis systems based on IMUs and FSRs have therefore been investigated. After studying a variety of research articles, the optimal locations of the FSR and IMU sensors were determined by analysing the main pressure points under the feet and prime anatomical locations on the human body. A total of seven locations (the big toe, heel, first, third, and fifth metatarsals, as well as two close to the medial arch) can be used to measure gate cycles for normal and flat feet. It has been found that IMU sensors can be placed in four standard anatomical locations (the feet, shank, thigh, and pelvis). A section on computational analysis is included to illustrate how data from the FSR and IMU sensors are processed. Sensor data is typically sampled at 100 Hz, and wireless systems use a range of microcontrollers to capture and transmit the signals. The findings reported in this article are expected to help develop efficient and cost-effective gait analysis systems by using an optimal number of FSRs and IMUs

Aspek Hukum Kebijakan Geothermal Di Indonesia

Penelitian ini bertujuan untuk mengetahui aspek hukum kebijakan pemerintah Indonesia dalam menguasai, mengatur hingga mengelola Geothermal Energi dalam bentuk kebijakan. Selain itu juga untuk menguraikan upaya hukum apa yang telah dilakukan yang berdasarkan berdasarkan peraturan Perundang-undangan yang berlaku dikaitkan dengan rangka pembangunan ketahanan energi nasional. Penelitian ini menggunakan metode pendekatan yuridis normatif, dengan jenis penelitian eksplanatoris, serta menggunakan sumber data sekunder yaitu dari peraturan Perundang-undangan yang berlaku dan bahan lain penjelas dari peraturan tersebut. Metode pengumpulan data dilakukan melalui studi literatur atau melalui studi kepustakaan untuk mendapatkan bahan hukum primer, sekunder maupun tersier. Hasil penelitian menunjukan bahwa upaya pemerintah Indonesia dalam memanfaatkan Geothermal Energi masih belum optimal sehingga belum dapat mendukung ketahanan energi nasional. pemanfaatan geothermal energi dalam rangka ketahanan energi nasional belum sepenuhnya maksimal jika dikaitkan dengan upaya hukum yang dilakukan oleh pemerintah selama ini. Energy panas bumi hanya termanfaatkan sejulam 05 % dari keseluruhan sumberdaya panas bumi yang dimiliki oleh pemerintah Indonesia. Kedepan, sudah saatnya pemerintah mulai mengoptimalkan pengelolaan Geothermal Energi demi terwujudnya pembangunan ketahanan energi nasional

Kecerdasan Emosi Dan Agresivitas Pada Remaja Akhir

If late adolescence has a good emotional intelligence, he/she will be able to control his/herreactions or behavior, including the aggression. The aim of this research is to gaindescription about emotional intelligence and aggresion in late adolescence, the correlation ofemotional intelligence and aggresion, the contribution of emotional intelligene dimensions toaggression, and the difference of emotional intelligence and aggresion in late adolescence.The participants of this research are 92 male and female late adolescents from 16-18 yearsold. The result shows negative correlations between emotional intelligence and aggresion inmale and female late adolescents. The other findings are only emphaty, self-awareness, andself-controll that have good impact on controlling the aggression. It reratas, the otherdimensions such as self-motivation and social skills only have small impact in controllingaggression. Furthermore, there is differentiation between male and female late adolescents inemotional intelligence and aggresion

Effect of In-ovo Injection of L-Arginine on Hatchability, Chick Quality, Performances and Muscle Histology of Native Chicken

This study aimed to determine the effect of in-ovo injection of L-arginine on hatchability, chick quality, performances, and muscle histology of native chicken. In-ovo injection was carried out on the 10th day. A total of 375 fertile eggs with an average weight ranged  39-43 g were grouped into 5 treatments. The first treatment was without injection (negative control), the second treatment was injection of NaCl solution 0.9% (positive control), the third treatment was injection of L-arginine solution 0.5 g per 100 ml of NaCl 0.9% (0.5%, m/v) The fourth treatment was injection of 1.0 g L-arginine solution per 100 ml of NaCl 0.9% (1.0%, m/v), and the fifth treatment was injection of 1.5 g L-arginine solution per 100 ml of NaCl 0.9% (1.5%, m/v). The injection was carried out at the pointed area of the egg in a vertical position (pointed below, blunt above). The Injection was carried out with a depth of 10 mm from the eggshell using an automatic injector. The results showed that all treatments produced the same hatchability. In-ovo injection of L-arginine has a beneficial effect on chick quality and post-hatch performance, the concentration of L-arginine solution used did not cause embryo death. In-ovo injection of 0.5% L-arginine increased hatching weight, weekly body weight, muscle mass, and myofiber size
