PRELIMINARY REVIEW OF MULTISCALE FRET AS INNOVATION OF ERGONOMIC GUITAR

The development of multiscale fret as innovation of ergonomic guitar concept aims to make this innovation applied more by guitar luthiers in designing a guitar signature that is modern and ergonomic. This concept has its own advantages, not only producing specific and organic tones, but also has benefits that can minimize the risk of repetitive strain injuries that are often experienced by guitar players. Therefore, multiscale fret has begun to be widely developed and has become one of the alternative innovations that can be applied by guitar luthiers that still adopt conventional fret concept. This paper conducts an preliminary information of the innovation of multiscale fret in a guitar that is associated with aspects of ergonomic comfort. In further research, this is expected to be a reference to understand the basic of multiscale fret and a stepping stone in conducting more systematic review regarding the effectiveness of the performance of human-centered musical instruments.

Design, Optimization and Analysis of Lifting Tackle using Ansys software

Lifting of heavy products and machinery’s is one of the major causes of injury in the working place or station. One of the incidents which took place in 2001, the Bureau of labor statics reported that over 28-35 percentage of disaster injuries were shoulder & back injuries. • Musculoskeletal injuries (MSIs) to arms, legs and joints and repetitive strain injuries of various sorts. • Overexertion. • Cumulative trauma. The above stated problems are the biggest factors in the injuries, which are noticed in labours while lifting and moving of heavy parts or machineries. • For detailed & more information about the injuries caused during lifting of heavy parts is mentioned in the site which is in bibliography. When an employee makes use of smart lifting practices, which are in means of mechanical gears or elements and electronics configuration which makes ease to lift any heavy products or machineries.

Engram: A Systematic Approach to Optimize Keyboard Layouts for Touch Typing, With Example for the English Language

Most computer keyboard layouts (mappings of characters to keys) do not reflect the ergonomics of the human hand, resulting in preventable repetitive strain injuries. We present a set of ergonomics principles relevant to touch typing, introduce a scoring model that encodes these principles, and outline a systematic approach for developing optimized keyboard layouts in any language based on this scoring model coupled with character-pair frequencies. We then create a keyboard layout optimized for touch typing in English by constraining key assignments to reduce lateral finger movements and enforce easy access to high-frequency letters and letter pairs, applying open source software to generate millions of layouts, and evaluating them based on Google’s N-gram data. We use two independent scoring methods to compare the resulting Engram layout against 10 other prominent keyboard layouts based on a variety of publicly available text sources. The Engram layout scores consistently higher than other keyboard layouts.

Development and calibration of drum-based rolling resistance testing machine for manual wheelchair components

BACKGROUND: Manual wheelchair users are at a high risk of repetitive strain injuries, carpal tunnel syndrome, and rotator cuff tears due to propelling their wheelchair for mobility. Rolling resistance (RR) is one of the key forces that leads to increased propulsion forces and risk of injuries. OBJECTIVE: To better understand the factors contributing to RR, we iteratively designed, developed, and validated a drum-based testing machine and test method. METHODS: As part of the validation of the system, we tested and compared 4 manual wheelchair wheels under a range of conditions including camber, toe in/out, tire pressure, surfaces, and speed. A treadmill was employed to simulate flat ground RR. RESULTS: A machine was effectively design, developed, and tested to measure RR. Tire type, surfaces, and toe were found to be the largest contributors to RR. Comparison of the drum-based system to flat ground revealed that an offset can be used to calculate overground RR from drum measurements. CONCLUSIONS: Ongoing work includes performing a comprehensive analysis of the degree to which each factor contributes to RR of commonly used casters and rear-wheels so that the wheelchair sector can work to reduce RR and the associated risk of repetitive strain injuries.

Covid-19 and E- consultation in Orthopaedics: Experience on delineating the spectrum of Orthopaedic disorders amenable to treatment via Tele-consultation

Context: Covid-19 pandemic and lockdown scenario has forced to shut down the Outpatient consultation in hospitals and clinics. It was challenging to help out the patient population who were routine health care seekers for maintenance and follow-up.Aims: To tackle the prevailing routine Orthopaedic health care issue due to Covid-19 lockdown strategy through Tele-consultation and to delineate the spectrum of Orthopaedic disorders that were amenable to treatment by e-Consultation.Methods and Material: We executed two Tele consultation designs (Call based and App based) for our institution to reach out to the patients. The Orthopaedic patient characteristics and disease management was documented and analyzed.Results: A total of 468 consultations with diverse Orthopaedic disorders including Congenital lesions, Developmental and Metabolic disorders, Infective disorders, inflammatory disorders, Traumatic disorders, Tumours, Degenerative disorders and Repetitive Strain Injuries were addressed.Conclusions: Clinical decision making through Tele-consultation in Orthopaedics is demanding. However, majority of routine Orthopaedic disorders are amenable to management.

Hubungan Durasi Penggunaan PlayStation dengan De Quervain’s Syndrome pada Pemain PlayStation di Rental PlayStation Kelurahan Puncak Sekuning Palembang Tahun 2016

De Quervain’sSyndrome adalah nyeri pada daerah prosesus stiloideus bagian distal tulang radius akibat inflamasi pembungkus tendo otot abductor pollicis longus dan extensor pollicis brevis yang disebabkan repetitive strain injuries (RSI) ataupun overuse, dengan tanda-tanda klasik positif tes Finkelstein. Pengguna PlaysStation melakukan kegiatan berulang (repetitive) yang berpotensi menyebabkan RSI. Penelitian ini dilakukan untuk mengetahui hubungan penggunaan PlayStation dengan De Quervain’s Syndrome pada pemain PlayStation di rental PlayStation Kelurahan Puncak Sekuning Palembang. Penelitian ini merupakan penelitian analitik observasional dengan desain cross-sectional yang dilakukan pada bulan Agustus-November 2016. Sampel penelitian ini berjumlah 97 pengguna PlayStation yang di ambil dengan cara consecutive sampling. Data didapatkan dari wawancara dan pemeriksaan tes Finkelstein. Hasil yang diperoleh dianalisis dengan uji statistik Chi-Square.Dari penelitian ini didapatkan 69 (71,1%) kasus De Quervain’s Syndrome. Uji statistik menunjukkan variabel durasi penggunaan PlayStation (p=0,034) memiliki pengaruh yang bermakna terhadap kejadian De Quervain’s Syndrome.Terdapat hubungan yang bermakna antara durasi penggunaan PlayStation terhadap De Quervain’s Syndrome.
