Kepuasan kerja menjadi masalah yang cukup menarik dan penting, karena terbukti memiliki pengaruh yang besar bagi individu maupun perusahan. Kepuasan kerja merupakan suatu sikap seseorang terhadap pekerjaan yang berhubungan dengan situasi kerja, kerja sama antara karyawan, imbalan yang diterima dalam kerja, dan hal-hal yang menyangkut fisik dan psikologis. Tujuan penelitian ini untuk mengidentifikasi kepuasan kerja perawat di bangsal medikal bedah. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis penelitian deskriptif. Adapun teknik analisa data dalam penelitian ini dengan analisa univariat untuk mendeskripsikan karekteristik dari variabel yang ada. Teknik pengambilan sampel menggunakan penyebaran kuesioner kepada perawat yang bekerja di rumah sakit tertentu di Kabupaten Timur Tengah Selatan dan Kota Kupang, sampel yang di ambil berjumlah 89 sampel. Hasil yang didapat dari penelitian ini rata-rata kepuasan kerja perawat berada pada kategori netral yang artinya perawat merasa apa yang sudah diterima sesuai dengan pekerjaan yang sudah mereka lakukan hal ini dilihat dari Sembilan kategori yang di telliti yaitu gaji, supervisi, tunjangan tambahan, penghargaan, kondisi kerja, promosi, sifat kerja dan komunikasi kecuali rekan kerja. Saran untuk peneiliti kedepannya agar dapat menggunakan variabel yang lain seperti well-being terhadap kepuasan kerja perawat yang bekerja di rumah sakit.   Kata kunci : kepuasan kerja, perawat   IDENTIFICATION OF NURSE WORK SATISFACTION THAT WORKED IN THE MEDICAL SURGERY OF SURGERY   ABSTRACT Job satisfaction is a problem that is quite interesting and important, because it has proven to have a great influence for individuals and for companies. Job satisfaction is a person's attitude towards work related to work situations, cooperation between employees, rewards received in work, and matters relating to physical and psychological. The purpose of this study was to identify job satisfaction of nurses in the surgical medical ward. This study uses a quantitative approach with a type of descriptive research. The data analysis techniques in this study were carried out by univariate analysis to describe the characteristics of the variables. The sampling technique used questionnaires to nurses who worked in certain hospitals in South Middle East District and Kupang City, the samples taken were 89 samples. . The results obtained from this study mean that the average job satisfaction of certain hospital nurses in East Tengah Selatan District and Kupang City is in the neutral category, which means nurses feel that what they have received is in accordance with the work they have done. telliti namely salary, supervision, additional benefits, rewards, working conditions, promotions, nature of work and communication except coworkers. Suggestions for future researchers to be able to use other variables such as well-being towards job satisfaction for nurses working in hospitals.   Keywords:  job satisfaction, nurse

Although Atrial Fibrillation (AF) is the most frequent cause of cardioembolic stroke, the arrhythmia remains underdiagnosed, as it is often asymptomatic or intermittent. Automated detection of AF in ECG signals is important for patients with implantable cardiac devices, pacemakers or Holter systems. Such resource-constrained systems often operate by transmitting signals to a central server where diagnostic decisions are made. In this context, ECG signal compression is being increasingly investigated and employed to increase battery life, and hence the storage and transmission efficiency of these devices. At the same time, the diagnostic accuracy of AF detection must be preserved. This paper investigates the effects of ECG signal compression on an entropy-based AF detection algorithm that monitors R-R interval regularity. The compression and AF detection algorithms were applied to signals from the MIT-BIH AF database. The accuracy of AF detection on reconstructed signals is evaluated under varying degrees of compression using the state-of-the-art Set Partitioning In Hierarchical Trees (SPIHT) compression algorithm. Results demonstrate that compression ratios (CR) of up to 90 can be obtained while maintaining a detection accuracy, expressed in terms of the area under the receiver operating characteristic curve, of at least 0.9. This highlights the potential for significant energy savings on devices that transmit/store ECG signals for AF detection applications, while preserving the diagnostic integrity of the signals, and hence the detection performance.

Abstract Background Emphasizing the active use of the arms and coordinating them with the stepping motion of the legs may promote walking recovery in patients with impaired lower limb function. Yet, most approaches use seated devices to allow coupled arm and leg movements. To provide an option during treadmill walking, we designed a rope-pulley system that physically links the arms and legs. This arm-leg pulley system was grounded to the floor and made of commercially available slotted square tubing, solid strut channels, and low-friction pulleys that allowed us to use a rope to connect the subject’s wrist to the ipsilateral foot. This set-up was based on our idea that during walking the arm could generate an assistive force during arm swing retraction and, therefore, aid in leg swing. Methods To test this idea, we compared the mechanical, muscular, and metabolic effects between normal walking and walking with the arm-leg pulley system. We measured rope and ground reaction forces, electromyographic signals of key arm and leg muscles, and rates of metabolic energy consumption while healthy, young subjects walked at 1.25 m/s on a dual-belt instrumented treadmill (n = 8). Results With our arm-leg pulley system, we found that an assistive force could be generated, reaching peak values of 7% body weight on average. Contrary to our expectation, the force mainly coincided with the propulsive phase of walking and not leg swing. Our findings suggest that subjects actively used their arms to harness the energy from the moving treadmill belt, which helped to propel the whole body via the arm-leg rope linkage. This effectively decreased the muscular and mechanical demands placed on the legs, reducing the propulsive impulse by 43% (p < 0.001), which led to a 17% net reduction in the metabolic power required for walking (p = 0.001). Conclusions These findings provide the biomechanical and energetic basis for how we might reimagine the use of the arms in gait rehabilitation, opening the opportunity to explore if such a method could help patients regain their walking ability.

Heavy eye syndrome is an important type of myopia-induced strabismus. We provide an overview of heavy eye syndrome, from its history to its most salient features. The theory of the orbital and rectus muscle pulley system as it relates to heavy eye syndrome and the prevailing theories on the pathophysiology of heavy eye syndrome in the current literature are discussed. We also highlight the presentation of heavy eye syndrome, its typical features on imaging, and differential diagnosis. Finally, we provide an overview on the management of heavy eye syndrome, including a description of several current surgical techniques.

Tissue Abnormalities

Wassel VI radial polydactyly is associated with metacarpal adduction and radial deviation of the metacarpophalangeal joint of the ulnar duplicate. The soft tissue abnormalities responsible for these deformities were characterized using preoperative multi-planar three-dimensional ultrasound and intraoperative observation in four patients. In all patients, the abductor pollicis brevis and superficial head of the flexor pollicis brevis inserted into the radial first metacarpal, whereas the adductor pollicis and deep head of the flexor pollicis brevis inserted into the ulnar thumb. Aberrant location of the flexor pollicis longus and absence of the A1 pulley system was associated with severe radial deviation. An additional superficial thenar muscle along the ulnar metacarpal was associated with minimal metacarpal adduction. Uneven forces on the ulnar duplicate could be associated with these characteristic deformities and joint instability. Knowledge of these abnormalities allows better planning of surgery and further insight into this rare radial polydactyly configuration. Level of evidence: II
