Asynchrony between tactile and auditory feedback (action-sound latency) when playing a musical instrument is widely recognized as disruptive to musical performance. In this paper we present a study that assesses the effects of delayed auditory feedback on the timing accuracy and judgments of instrument quality for two groups of participants: professional percussionists and non-percussionist amateur musicians. The amounts of delay tested in this study are relatively small in comparison to similar studies of auditory delays in a musical context (0 ms, 10 ms, 10 ms ± 3 ms, 20 ms). We found that both groups rated the zero latency condition as higher quality for a series of quality measures in comparison to 10 ms ± 3 ms and 20 ms latency, but did not show a significant difference in rating between 10 ms latency and zero latency. Professional percussionists were more aware of the latency conditions and showed less variation of timing under the latency conditions, although this ability decreased as the temporal demands of the task increased. We compare our findings from each group and discuss them in relation to latency in interactive digital systems more generally and experimentally similar work on sensorimotor control and rhythmic performance.

Speech Control

Forty stutterers and 40 nonstutterers were tested for susceptibility to delayed auditory feedback (DAF) while reading passages under amplified delay conditions. Susceptibility to DAF of stutterers was significantly higher than that of nonstutterers. In the nonstuttering group, men were more susceptible to DAF than women, but in the stuttering group, there was no significant difference between sexes. There was also no significant difference in DAF susceptibility between stuttering men and nonstuttering men. Nonstuttering women were least susceptible to DAF. A Susceptibility Index (SI) was found to discriminate speaker sensitivity to DAF and was interpreted to suggest that stutterers rely on auditory feedback for speech control more than nonstutterers.

Binaurally asynchronous delayed auditory feedback (DAF) was compared with synchronous DAF in 80 normal subjects. Asynchronous DAF (0.10 sec difference) did not yield results different from those obtained under synchronous DAF with a 0.20 sec delay interval, an interval characteristically resulting in maximum disruptions in speech.

Quality of work life is the major factor to be considered in working environment of any organization. The performance of employees and the organization lies on the ability of the employees based on working environment. The QWL leads to better working environment which improves the performance of organization. The present study has made an attempt to find the level of factors causing QWL and the impact of outcome of QWL in banks. Since the profile of the banks may be associated with the level of outcomes of QWL, the present study has made an attempt to examine it with the help of one way analysis of variance and t-test. The included outcomes of QWL are job satisfaction, job stress, organizational climate, organizational commitment, employees retention behaviour, service quality employees and service productivity of employees. The highly associated determinants of QWL and the significant difference among the PUSBs and PRSBs have been noticed. The significantly associating important profiles of the banks regarding the existence of outcome of QWL are identified.

Background: The criteria set of assessing hospital quality in Vietnam in 2016 was revied from the criteria set in 2013 by the Ministry of Health in order to help hospitals to self-assess towards improvinge quality of hospitals in the international integration context. The study aimed to assess the quality of public hospitals in Can Tho City according to the revised criteria set of the Ministry of Health in 2016 and compare the quality among three hospital ranks (including grade I, grade II, and grade III) via to 5 groups of quality criteria. Methods: A cross-sectional study, using secondary data analysis was applied to assess the service quality of 7 general public hospitals in Can Tho City. Results: The average total score of 7 hospitals is 245 and the average for the criteria of 7 hospitals is 2.99, which is just satisfactory. In the criterion of quality, criterion D and E had the lowest scores compared to the other three groups. There was no statistically significant difference (p = 0.076) among the mean scores for the three hospital categories. Conclusion: The quality of public hospitals in Can Tho city in 2016 only reached moderately good level (2.99). Interventions should be developed to improve the quality of hospitals, with particular emphasis on improving the quality of criteria groups D and E.

SummaryAim: Assessment of the clinical benefit of i.v. contrast enhanced diagnostic CT (CE-CT) compared to low dose CT with 20 mAs (LD-CT) without contrast medium in combined [18F]-FDG PET/CT examinations in restaging of patients with lymphoma. Patients, methods: 45 patients with non-Hodgkin lymphoma (n = 35) and Hodgkin's disease (n = 10) were included into this study. PET, LD-CT and CECT were analyzed separately as well as side-by-side. Lymphoma involvement was evaluated separately for seven regions. Indeterminate diagnoses were accepted whenever there was a discrepancy between PET and CT findings. Results for combined reading were calculated by rating indeterminate diagnoses according the suggestions of either CT or PET. Each patient had a clinical follow-up evaluation for >6 months. Results: Region-based evaluation suggested a sensitivity/specificity of 66/93% for LD-CT, 87%/91% for CE-CT, 95%/96% for PET, 94%/99% for PET/LD-CT and 96%/99% for PET/CE-CT. The data for PET/CT were obtained by rating indeterminate results according to the suggestions of PET, which turned out to be superior to CT. Lymphoma staging was changed in two patients using PET/ CE-CT as compared to PET/LD-CT. Conclusion: Overall, there was no significant difference between PET/LD-CT and PET/CE-CT. However, PET/CE-CT yielded a more precise lesion delineation than PET/LD-CT. This was due to the improved image quality of CE-CT and might lead to a more accurate investigation of lymphoma.

The Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.

In recent years, breast cancer (BC) is the most common cancer pathology and the most common cause of disability among women in developed countries. Finding the most effective ways of interaction between the patient and the doctor creates the preconditions for the necessary analysis of the treatment process from an objective and subjective point of view. Therefore, an important indicator to be taken into account is the quality of life of a patient. To compare the indicators of a comprehensive assessment of the quality of life of patients to the adverse locally advanced forms (LA) of breast cancer before and after systemic intravenous polychemotherapy (SPCTx) and selective endolymphatic polychemotherapy (ELPCTx) in neoadjuvant mode. The study was conducted on the basis of a random analysis of outpatient cards from 112 patients with LA BC T4A-DN0-3M0 who received a comprehensive antitumor treatment on the basis of the Donetsk regional antitumor center and the University Clinic of the Odessa National Medical University from 2000 to 2017, which was proposed a questionnaire at various stages of preoperative treatment. The first (control) group consisted of 65 patients (58 %) with inoperable forms of LA BC, which was performed in neoadjuvant mode by SPCTx. The second (study group) included 47 patients (42 %) with inoperable forms of LA BC, which was performed as a neoadjuvant course ELPCTx. According to the integral indicators of quality of life and quality of health between patients in the control and study groups, there was no statistically significant difference. In a detailed analysis of the indicators of symptomatic scales, the difference between the groups did not exceed the critical. Based on the results of a study conducted among patients receiving endolymphatic chemotherapy in a neoadjuvant mode, the subjective evaluations of treatment in absolute numbers have better reference values without statistical superiority. The study of the integrative indicator of quality of life and its discrete elements is an ergonomic and economical means of heuristic assessment of the health of patients in order to further develop more rational and convenient ways of solving urgent issues of modern oncology by increasing compliance and finding a compromise between the physician and the patient.
