AbstractAttention is a complex cognitive function that is necessary for learning, for following social norms of behaviour and for effective performance of responsibilities and duties. It is especially important in sensitive occupations requiring sustained attention. Improvement of dietary diversity (DD) is recognised as an important factor in health promotion, but its association with sustained attention is unknown. The aim of this study was to determine the association between auditory and visual sustained attention and DD. A cross-sectional study was carried out on 400 women aged 20–50 years who attended sports clubs at Tehran Municipality. Sustained attention was evaluated on the basis of the Integrated Visual and Auditory Continuous Performance Test using Integrated Visual and Auditory software. A single 24-h dietary recall questionnaire was used for DD assessment. Dietary diversity scores (DDS) were determined using the FAO guidelines. The mean visual and auditory sustained attention scores were 40·2 (sd35·2) and 42·5 (sd38), respectively. The mean DDS was 4·7 (sd1·5). After adjusting for age, education years, physical activity, energy intake and BMI, mean visual and auditory sustained attention showed a significant increase as the quartiles of DDS increased (P=0·001). In addition, the mean subscales of attention, including auditory consistency and vigilance, visual persistence, visual and auditory focus, speed, comprehension and full attention, increased significantly with increasing DDS (P<0·05). In conclusion, higher DDS is associated with better visual and auditory sustained attention.

Background. One of the most problematic regions for endosseous implants is the posterior maxilla, not only having poor bone density, but also lacking adequate vertical height as a result of sinus pneumatization. The purpose of the present study was a radiologic, histological, and histomorphometrical evaluation, in humans, of specimens retrieved from sinuses augmented with decellularized bovine compact particles, after a healing period of 6 months. Methods. Four patients, with atrophic resorbed maxillas, underwent a sinus lift augmentation with decellularized bovine compact bone from bovine femur. The size of the particles used was 0.25–1 mm. A total of four grafts and 5 biopsies were retrieved and processed to obtain thin ground sections with the Precise 1 Automated System. Results. The mean volume after graft elevation calculated for each of the 4 patients was 2106 mm3 in the immediate postoperative period (5–7 days), ranging from 1408.8 to 2946.4 mm3. In the late postoperative period (6 months) it was 2053 mm3, ranging from 1339.9 to 2808.9 mm3. Histomorphometry showed that newly formed bone was 36±1.6% and marrow spaces were 34±1.6%, while the residual graft material was 35±1.4%. Conclusion. In conclusion, based on the outcome of the present study, Re-Bone® can be used with success in sinus augmentation procedures and 6 months are considered an adequate time for maturation before implant placement.

The purpose of this study is to compare presentation methods for use in the validation of the Trust in Selfdriving Vehicle Scale (TSDV), a questionnaire designed to assess user trust in self-driving cars. Previous studies have validated trust instruments using traditional videos wherein participants watch a scenario involving an automated system but there are strong concerns about external validity with this approach. We examined four presentation conditions: a flat screen monitor with a traditional video, a flat screen with a 2D 180 video, an Oculus Go VR headset with a 2D 180 video, and an Oculus Go with a 3D VR video. Participants watched eight video scenarios of a self-driving vehicle attempting a right-hand tum at a stop sign and rated their trust in the vehicle shown in the video after each scenario using the TSDV and rated telepresence for the viewing condition. We found a significant interaction between the mean TSDV scores for pedestrian collision and presentation condition. The TSDV mean in the Headset 2D 180 condition was significantly higher than the other three conditions. Additionally, when used to view the scenarios as 3D VR videos, the headset received significantly higher ratings of spatial presence compared to the condition using a flatscreen a 2D video; none of the remaining comparisons were statistically significant. Based on the results it is not recommended that the headset be used for short scenarios because the benefits do not outweigh the costs.

Development and practical implementation of the enterprise industrial safety management system considering the new requirements of the legislation on creation of the state system for monitoring, remote control, technical certification, and diagnostics of technical devices at hazardous production facilities supervised by Rostechnadzor is discussed in the article. To perform automated collection, recording, generalization, systematization, and evaluation of the information on the parameters that characterize safety of the enterprise hazardous equipment as a whole and each technical device, a block diagram of the enterprise automated industrial safety management system is proposed. The basics are suggested for creating the automated system containing a database that includes all the technical documentation, certificates and expert opinions, repair documentation and accompanying documents (orders, instructions, audit conclusions, etc.) for the efficiency of tracking the technical condition in real time considering changes in all the controlled parameters of the enterprise technological complexes. It is noted in the article that the assessment of the technical condition and life of single and unique technical devices that make up the bulk of equipment in hazardous production should be carried out already at the manufacturing stage by combining technical control with technical diagnostics, and their results should be included in the technical passport of the device. The need in this information for the operators is invaluable, especially after working out the manufacturer’s designated period of safe operation and for evaluating the actual technical condition and comparing it with its original, which was documented during fabrication. Data on the initial state allows to qualitatively assess the degradation processes that are developing during operation and consider them when evaluating the life of a technical device and conduct a qualitative audit of the industrial safety management system.

AbstractBackground: Despite of the use of tangential beam directions during the irradiation of mammary carcinomas, a dose reduction of the heart cannot always be achieved. This is decivise for the increased risk of heart diseases and the associated mortality. Especially affected is the cardiac apex. However, by using respiratory gated treatment techniques, like the deep inspiration breath-hold (DIBH), a dose sparing of this area can be reached.Material and Methods: The Elekta ABC system was used to control the respiratory stop of early staged breast cancer patients. The treatment planning was implemented by a 3D and VMAT technique. The focus was the optimization of irradiation plans and the evaluation of the respective dose exposure to the heart, the left ventricle and the left anterior descending coronary artery (LAD artery). A planning concept of 28 x 2,25 Gy in the SIB and 28 x 1,8 Gy in the left breast was used.Results: The results showed that a dose reduction of 30-40% in mean and maximal in all structures is possible by using the VMAT technique in combination with the ABC system. In the case of 3D irradiation planning, a substantial relief can only be seen at the mean dose exposure of approximately 50%. Also, only a maximum dose reduction of 13% could be achieved.Conclusion: The mean dose reduction was mainly achieved by the increased distance between the heart and the thorax wall. The maximum dose was reduced by the volumentric optimization algortihm of the VMAT and the resulting steeper dose fall-off at the inner thoracic wall. Due to the lack of this optimization and thus the greater dose drop, the maximum dose of the 3D plans could only reduced by 13%.

Abstract Data were gathered, during a study on the development of an automated system for the extraction, cleanup, and quantitation of mycotoxins in corn, to determine if it was scientifically sound to reduce the analytical sample size. Five, 10, and 25 g test portions were analyzed and statistically compared with 50 g test portions of the same composites for aflatoxin concentration variance. Statistical tests used to determine whether the 10 and 50 g sample sizes differed significantly showed a satisfactory observed variance ratio (Fobs) of 2.03 for computations of pooled standard deviations; paired f-test values of 0.952, 1.43, and 0.224 were computed for each of the 3 study samples. The results meet acceptable limits, since each sample’s r-test result is less than the published value of the |t|, which is 1.6909 for the test conditions. The null hypothesis is retained since the sample sizes do not give significantly different values for the mean analyte concentration. The percent coefficients of variation (CVs) for all samples tested were within the expected range. In addition, the variance due to sample mixing was evaluated using radioisotopelabeled materials, yielding an acceptable CV of 22.2%. The variance due to the assay procedure was also evaluated and showed an aflatoxin B, recovery of 78.9% and a CV of 11.4%. Results support the original premise that a sufficiently ground and blended sample would produce an analyte variance for a 10 g sample that was statistically comparable with that for a 50 g sample.

Abstract We have automated a manual test for detection of heterozygotes of Tay-Sachs disease by assay of hexosaminidase A in serum, based on pH inactivation [Clin. Chim. Acta 43, 417 (1973)]. The same manifold is used both for the total hexosaminidase and pH-inactivation (hexosaminidase B) procedures. Automation expedites mass screening of the Ashkenazi Jewish population for carriers of the Tay-Sachs gene (prevalence rate, 1:30), because 100 or more tests can be performed daily. The mean percentage value and range (±2 SD) of hexosaminidase A for normal adults is 68.6 (58-79) and for carriers is 48.8 (39-59) with the automated pH-inactivation procedure. "Presumed carriers" (&lt;53% hexosaminidase A) and individuals in the uncertain range (53 to 58%) should be retested by using leukocytes, to avoid the effect of certain physical ailments, before being labeled as carriers. The same automated system used for this assay can also be used to detect carriers of at least seven other sphingolipidoses for which artificial fluorogenic substrates are available.

A practical implementation of generalized multimodal pushover analysis is presented in this study, where the number of pushovers is reduced significantly in view of the number of modes contributing to seismic response. It has been demonstrated in two case studies that the reduced procedure for generalized push-over analysis is equally successful in estimating the maximum member deformations and forces under a ground excitation with reference to nonlinear response history analysis. It is further shown that the results obtained by using the mean spectrum of a set of ground motions are almost identical to the mean of the results obtained from separate generalized pushover analyses. These results are also very close to the mean results of the nonlinear response history analyses, hence motivating the implementation of generalized pushover analysis with design spectrum.

Abstract   At the present stage of development of any state, an important aspect of occupational health and public health is undoubtedly the protection of workers' health. In view of this, we have developed an automated system and algorithm for the approach to assessing professional risks. It is proposed to implement a campaign to manage occupational health risks for workers through the automated system “Software complex for monitoring and managing occupational health risks for workers at an industrial enterprise” developed in the Republic of Kazakhstan. This complex performs the necessary actions to create the foundations for making management decisions, it consists of the following components, which were analyzed and used at the industrial enterprise Joint Stock Company ‘Kostanay Minerals' in the Republic of Kazakhstan: 1) analysis of current information based on the definition and systematization of the information bases of the enterprise. Such databases include data on employees, working conditions, cases of injuries, morbidity, medical examinations, occupational morbidity and personal protective equipment; 2) the analytical component, carried out on the basis of statistical data, mathematical methods of information processing, conducts an analysis of professional risk both for each worker and for each enterprise. The analysis of the data is presented by the system in the form of reports received by the interested person of the enterprise by specifying a sample of data in any form, with the specification of the conditions for sampling from the stored data in the database of the automated system. The developed and implemented approach to occupational risk management is aimed at the practical implementation of a comprehensive risk assessment at workplaces, allowing not only to identify risks, but also to manage them during the work shift, throughout the entire work experience, which is the basis for ensuring the safety and health of industrial workers. Key messages The introduction of new technologies in industry will lead to a sharp decrease in the intensity of production factors and occupational pathology and to conduct a correct assessment of health risks. Professional risk monitoring consists in informing employees, employers, the public, administrative authorities about the risk factors at work and the necessary and applied measures to reduce it.

Abstract We have evaluated the Technicon SMA 12/60 modification of a glucose oxidase/peroxidase-3-methyl-2-benzothiazolinone hydrazone-N, N-dimethylaniline method, and find it acceptable. Added bilirubin, creatinine, dextrans, and uric acid did not interfere. We compared values for patients’ sera by this method to those by the glucose oxidase/peroxidase-2,2'-azinodiethylbenzothiazoline-6-sulfonic acid, neocuproine, o-toluidine, ferricyanide, and hexokinase methods. For comparisons to the hexokinase method (which we used as a reference method), n = 371, slope = 1.00, y-intercept = 1.57 mg/dl, and bias = 2.05 mg/dl. For the method being evaluated, the run-to-run average monthly standard deviation was 2.9 mg/dl for a control product for which the mean was 85 mg of glucose per deciliter, and 4.3 mg/dl for a product for which the mean was 240 mg/dl. All six methods were compared for effects of uremic sera, icteric sera, and sera from patients receiving ascorbic acid therapy or hypoglycemic drugs.
