Short Test

In developing the Accident Proneness Prediction Test to measure motor control skills related to safety aptitudes subjects were instructed to draw on a sheet of paper as many circles as possible within a limited amount of time. The responses were scored in terms of the speed and quality (irregularities) of the produced circles. Although 103 accident-prone drivers produced more circles than the 178 good drivers, the quality of performance of the accident-prone drivers was poorer than that of the good drivers. Based on this validity study, we proposed these predictive criteria for further testing of accident proneness.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor.

Most modern agricultural machines and tools consist of components, the main parameters, design features of which were justified in the first half of the twentieth century. Slowly and evolutionarily, these technical means are developing. (Research purpose) The research purpose is in identifying general trends in the technical and technological level of steam cultivators in the first quarter of the XXI century. (Materials and Methods) For the study there was analyzed the data of the short test reports of the selected machines. The production of steam cultivators in the Russian Federation is gradually increasing. (Results and discussion) For ten years of the beginning of the XXI century, only 27 machines were provided for testing, and from 2014 to 2017 – more than 40, while for "old" cultivators, the weighted average value of the tractor traction class was 2.8, for new ones it is about of four. For the study period (on average 10 years) the quality of soil cultivation in terms of such parameters as deviation from the specified depth of cultivation, crumbling and combing of the field surface has not changed much. The productivity of cultivator units increased by 7-21 percents, which is explained not only by an increase in the power of tractors, but also by an increase in the utilization rate of charge time on average from 0.72 to 0.77. The specific weight of the "new" cultivators was on average 22 kilogram-meters less than that of the "old" analogues, which can be explained by the evolution of their designs. (Conclusions) Increasing the class of tractors by one "level" the specific material consumption of the cultivators aggregated with them increases by about 58 kilogram-meters for both "old" and " new " cultivators. With an increase in the width of the tools from 4 to 16 meters, their weight will increase by 8 times, which affects the cost and operational and environmental characteristics of wide-reach cultivators.

Theoretical Proposal

Adopting a strictly motor approach to linguistic organization, the theoretical proposal called Molde e Conteúdo (Davies & Macneilage 1995; Macneilage & Davies 1966) argues that the first child production akin to adult speech – canonical babbling – can be seen as a motor correlate of the molde silábico. Moldes constitute a rhythmic basis catalyzing specific syllabic or segmental sequences. The independent motor control of such elements emerges gradually from jaw/tongue synergies with which the child initiates a type of vocal production similar to the adult’s. In the acquisition of speech production skills, then, changes in the quality of sounds in an utterance are initially based in changes in the amplitude of the jaw opening/closing cycle, i.e., they determine intra-syllabic organization. Syllables sequences, in turn, comprise vocalic and consonantal qualities produced in homorganic articulation places (i.e. front consonants with front vowels; back consonants with back vowels), as demonstrated child data derived from six different linguistic communities – English, Swedish, French, Japanese (in the Stanford database), Brazilian Portuguese (Teixeira & Davies 1999) e Equatorial Quichua (Gildersleeve-Neumann, doctoral dissertation in preparation, U. Texas, Austin). In general, the data on Brazilian Portuguese acquisition are comparable to production universal patterns reported for children in different languages, but also show specific characteristics due to the ambient language pressure.

Hasil analisis multivariat menggunakan uji regresi logistik prediksi menunjukkan adanya hubungan yang signifikan antara proses organisasi dengan efektivitas organisasi, baik pada pendekatan sentralisasi maupun desentralisasi (p< 0,05, α= 0,05). Pada aspek efektivitas, hasil penelitian menunjukkan hasil 31,7% pada pendekatan sentralisasi dan 42,3% pada pendekatan desetnralisasi. Untuk itu, pihak manajemen rumah sakit perlu mengupayakan berbagai strategi manajemen keperawatan untuk meningkatkan efektivitas dan mutu pelayanan keperawatan di rumah sakit. AbstractThe objective of this research is to find out the relationship within organizational process (communication, decision making, career socialization, and career opportunity) and the effectiveness of the organization in giving nursing care using centralization approach and decentralization approach in Hospital. The questioners were given to a total sample of 104 respondents; they were associate nurses who were chosen using inclusion criteria. The relationship between independent and dependent variable, and the test to differentiate each variable in both centralization and decentralization approach were tested using chi-square analysis. The multivariate analysis using logistic regression prediction test showed that there was a significant relationship between organizational process and the effectiveness of the organization, both in centralization and decentralization approach (p< 0,05; α= 0,05). Moreover this study also showed that the effectiveness in centralization approach was 31.7%, whilst in the decentralization approach was 42.3%. It is recommended that the hospital's management should apply several strategies of management in nursing in order to increase the effectiveness and the quality of nursing services in hospital.

Questionnaire Assessment

The purpose of the paper is a functional assessment of post-mastectomy patients who underwent latissimus dorsi breast reconstruction (LDBR), and of healthy women, through an analysis of selected muscle function parameters, including motor control assessment. Twenty participants were included in the study (ten LDBR-procedure individuals and ten healthy controls). The research consisted of a DASH (The Disabilities of the Arm, Shoulder and Hand) questionnaire assessment, shoulder area static assessment, shoulder mobility assessment, latissimus dorsi flexibility assessment and shoulder motor control assessment. LDBR-procedure individuals—when compared to healthy controls—exhibited a decrease in physical aspects of quality of life, shoulder area postural alterations, limitations in shoulder mobility and decrease in shoulder motor control. LDBR procedure may have an influence on limiting shoulder active mobility, as well as on decrease of shoulder motor and postural control. Standard functional assessment diversified on motor control assessment of post-mastectomy patients qualified for the LDBR procedure seems to be necessary.

Abstract BackgroundMillions of individuals suffer from upper extremity paralysis caused by neurological disorders including stroke, traumatic brain injury, spinal cord injury, or other medical conditions. In order to restore motor control and enhance the quality of life of these patients, daily exercises and strengthening training are necessary. Robotic hand exoskeletons can substitute for the missing motor control and help to restore the functions performed in daily operations. They can also facilitate neuroplasticity to help rehabilitate hand function through routine use. However, most of the hand exoskeletons are bulky, stationary, and cumbersome to use.Methods We have utilized a recent design of a hand exoskeleton (Tenoexo) and modified the design to prototype a motorized, lightweight, fully wearable rehabilitative hand exoskeleton by combining rigid parts with a soft mechanism capable of producing various grasps needed for the execution of daily tasks. We have tested the performance of our developed hand exoskeleton in restoring hand functions in two quadriplegics with chronic cervical cord injury.ResultsMechanical evaluation of our exoskeleton showed that it can produce fingertip force up to 8 N and can cover 91.5 degree of range of motion in just 3 seconds. We further tested the robot in two quadriplegics with chronic hand paralysis, and observed immediate success on independent grasping of different daily objects. ConclusionsThe results suggest that our exoskeleton is a viable option for hand function assistance, allowing patients to regain lost finger control for everyday activities.
