The quality of bearing production has an impact not only on their reliability and lifetime, but also on the dynamic load of the working and living environment by excessive vibration and thus also noise. The intensity of the noise emitted by a bearing which is perceived by man characterizes the quality of its production. Reducing the dynamic load of mechanical systems and their components is reflected in the working environment by reducing noise emissions and immissions. The article proposes an objective method of bearing quality assessment based on measuring vibro-acoustic parameters of dynamic load of a new bearing using FFT analysis and the magnitude of the amplitude of bearing vibration acceleration and compares it with a subjective method that also uses the human auditory organ to assess bearing quality. The results of vibro-acoustic measurements were analysed in terms of vibration intensity and the noise of the produced bearings. The proposed objective methodology was compared with the subjective evaluation of the quality of bearings and the results of this methodology matched. The proposed methodology is applicable to all types of bearings, and it is possible to automate this methodology in the production process.

SummaryWe are still confronted by numerous different nosographic models and problems concerning the objective evaluation of patients progress during treatment. It is interesting to consider the consequences of this situation in psychiatry which still involves a relative diversity of practical methods used in clinical trials. The recommendations of the USA Food and Drug Administration, on the one hand, constitute a highly structured and precise reference. The World Health Organization, on the other hand, promulgates general recommendations resulting from a compromise designed to satisfy the greatest number of clinicians.Despite the apparently diverse principles and the different practical methods they propose, both those sets of recommendations have been useful in inspiring clinicians to reflect upon these different methodological approaches. The qualities of the inclusion criteria used in the study of patients and the sensitivity of the different measuring instruments have allowed psychotropic drug users as well as producers to recognize the need for a certain rigour in clinical trials.The FDA and WHO guidelines have certainly improved the quality of clinical trials in psychopharmacology. However, they also represent a source of resistance to innovation.A series of consensus meetings to first reconcile US and European points of view and later to include new techniques in the recognized sets of methods would therefore be helpful.

Abstract INTRODUCTION This study presents the first steps and results towards the development of a system for predicting the quality of surgical performance and workload in laparoscopic training. MATERIAL AND METHODS Surgeons wore a smartwatch which recorded their heart rate and hand motion during each laparoscopic procedure. Data was then correlated with both the Surgery Task Load Index (SURG-TLX) subjective questionnaire and the Global Operational Assessment of Laparoscopic Skills (GOALS) objective evaluation tool. Statistical analysis was conducted in order to study the relationship between parameters and to compare the results according to the surgeons’ level of experience. RESULTS Nine laparoscopic surgeons participated in this study, five gynecologists and four digestive surgeons. Gynecological surgeons showed a positive correlation between their level of experience, heart rate, hand motion, and GOALS score, except for bimanual dexterity. The reduction in the variability of hand accelerations led to improved tissue handling. Digestive surgeons showed a negative correlation between their level of experience and the reported temporal demand and complexity of the procedure. Novice digestive surgeons reported increased workload during surgery, mainly in mental, physical, and temporal workload. In both surgical specialties, it was observed that reduction in surgical workload was associated with improved GOALS score. CONCLUSIONS Preliminary results showed that bimanual dexterity is independent of the experience of gynecological surgeons. During laparoscopic surgical procedures, reduced variability in hand accelerations leads to better tissue manipulation. In addition, in gynecological and upper gastrointestinal procedures, reduced surgical workload is associated with improved surgical performance.

BACKGROUND: Preservation of quality of life regarding fecal continence after abdominoperineal excision (APE) in cancer is challenging. Simultaneous soft tissue coverage and restoration of continence mechanism can be provided through an interdisciplinary collaboration of colorectal and plastic reconstructive surgery. OBJECTIVE: Evaluation of surgical procedure and outcome combining soft tissue reconstruction using a central perforated vertical rectus abdominis myocutaneous flap (VRAM), implementing a perineostoma and restoring anorectal angle augmenting the levator ani by neurostimulated graciloplasty. METHODS: 14 Patients underwent APE due to cancer. In all patients coverage was achieved by pedicled VRAM and simultaneous pull-through descendostomy (perineostoma). 10 of those patients received a levator augmentation additionally. Postoperative complications, functional measures of continence as well as quality of life were obtained. RESULTS: Perineal minor complication rate was 43% without need of surgical intervention. All but one VRAM survived. Continence measures and disease specific life quality showed a good preservation of continence in most patients. CONCLUSION: The results present a complex therapy option accomplished by a collaboration of two highly specialized partners (visceral and plastic surgery) after total loss of the sphincter function and consecutive fecal insufficiency after APE.

The article deals with the results of the analysis of international and domestic experience in the use of network services, which can independently evaluate the quality of electronic publications and scientists’ publication activity. It can be achieved by the analysis of the values of scientometric indicators included in the bibliometric open electronic systems. This approach is associated with certain risks of objective evaluation of researchers’ scientific activity efficiency. The conditions for the inclusion of scientific publications in the search systems like Google Scholar are considered. It is concluded that the scientometric base, which is today an international and widely used in practice, should be developed to provide a more adequate reflection of the character and level of scientists’ scientific activity, as well as their personal contribution to the development of certain areas of science.

Before And After

Objectives: This study investigates the effect of electro-acupuncture on aphasia after stroke.Methods: A search of OASIS, NDSL, PubMed, Cochrane, and CNKI was executed between 4 January 2021 and 4 February 2021, with no limitation on publication year. Extraction and selection from the studies were made by 3 authors. The quality of the studies was evaluated using Cochrane’s risk of bias (RoB) tool.Results: 10 studies met the selection criteria. As the treatment site for electro-acupuncture, GV20 (Baihui) was used the most. In all studies, the region located on the head was used for treatment without distinguishing between acupoints and areas of scalp acupuncture, and the stimulation was organized into 3 conditions: speed, intensity, and time. The outcome indicators used before and after treatment focused on the evaluation of language function and the degree of aphasia. The results showed that using electro-acupuncture with speech rehabilitation therapy for aphasia after stroke was more effective than using speech rehabilitation therapy alone.Conclusions: In this review, electro-acupuncture for aphasia after stroke was found to have a significant effect compared to the previous treatment alone. However, because of limitations, information was not reliable enough. Additional research is needed to produce more objective evidence.

Sentiment analysis is a natural language processing (NLP) task of identifying orextracting the sentiment content of a text unit. This task has become an active research topic since the early 2000s. During the two last editions of the VLSP workshop series, the shared task on Sentiment Analysis (SA) for Vietnamese has been organized in order to provide an objective evaluation measurement about the performance (quality) of sentiment analysis tools, and encouragethe development of Vietnamese sentiment analysis systems, as well as to provide benchmark datasets for this task. The rst campaign in 2016 only focused on the sentiment polarity classication, with a dataset containing reviews of electronic products. The second campaign in 2018 addressed the problem of Aspect Based Sentiment Analysis (ABSA) for Vietnamese, by providing two datasets containing reviews in restaurant and hotel domains. These data are accessible for research purpose via the VLSP website vlsp.org.vn/resources. This paper describes the built datasets as well as the evaluation results of the systems participating to these campaigns.
