Full textAbstract:
The aim of the work is a theoretical study of the efficiency of heat supply based on a software package that includes mathematical models of a real CHPP, a real heating network and real heat consumers with a high share of hot water supply load using extended and reduced temperature schedules of heating regulation. The set aim is achieved by solving the following problems: choosing a method for calculating various schedules of regulating heat supply from CHPPs; construction of initial, reduced and extended temperature schedules and schedules of delivery water consumption; determination of optimal energy costs and heat-transfer agent costs. The most important of the results achieved is the carried analysis of the energy and economic efficiency indicators changes during the transition from the traditional to lowered and extended schedules of heat-supply system regulation. The total fuel savings at CHPP during the transition from the initial design temperature schedule with a maximum delivery water temperature of 150°C to the most energy efficient schedules reaches about 2%, which should be recognized as very significant. The significance of the obtained results lies in the fact that they allow calculating the energy effect in the form of fuel savings at CHPPs compared to their operation with the design temperature schedule. It is shown that the use of these technologies will increase the efficiency of district heating that will ensure a reliable and high-quality supply of heat energy to consumers and reduce its cost.

Full textAbstract:
In cold regions, weather introduces a great deal of uncertainty to weather-sensitive construction activities, resulting in project schedules that deviate from plans. To maximize construction process productivity, decisions regarding process execution planning and sequence of work need to be made, based on reliable plans and schedules. Faced with winter weather uncertainty in cold regions, this task becomes quite challenging. This paper follows the framework that was proposed in the literature for simulating weather-sensitive construction projects executed under cold weather conditions. In the literature, the authors applied the framework steps to enable simulating and planning pipeline construction activities under severe cold weather. The proposed framework sets out a work breakdown structure of activities to account for and quantify weather impact on the project schedule. The steps outlined in the framework are followed to enable simulating and planning tunnelling construction activities executed under severe cold weather conditions. Relevant simulation findings, which clarify the impact of cold weather events on construction projects and can assist in project planning and decision support, are reported.

Full textAbstract:
The current study reexamined the factor structure of the Lifetime and Recent scales of the Schedule of Sexist Events (SSE; Klonoff & Landrine, 1995 ) and conducted the first factor analysis of the SSE-Appraisal scale ( Landrine & Klonoff, 1997 ). Factor analyses conducted with data from 245 women yielded, for SSE-Lifetime and SSE-Appraisal scales, two reliable factors that can be scored as “Intimate and Personal Experiences of Sexist Events” and “Unfair Treatment Across Public Contexts” subscales. Data from the SSE-Recent scale yielded three factors that can be scored as “Sexist Degradation and Its Consequences,” “Unfair and Sexist Events at Work/School,” and “Unfair Treatment in Distant and Close Relationships” subscales. Recommendations are made for the future use of these proposed subscales in conjunction with total scale scores in research using the SSE to examine links between reported experiences of sexist events and women's health and well-being.

Full textAbstract:
Purpose Good planning is key to good project performance. However, for the sub-class of round-the-clock projects requiring mixed mode planning a suitable planning approach does not exist. The purpose of this paper is to develop and validate such an approach. Design/methodology/approach Development of the approach builds on a synthesis and extensions of previous work related to projects with round-the-clock schedules, containing multiple workflows (sequential/cyclical). This approach considers the interdependence among shift-schedule, productivity, calendar duration, and risk registers. It quantifies the confidence in those strategies using a Monte Carlo and a multi-dimensional joint confidence limit (JCL) simulation platform. Findings n of workflows and their interdependencies. Also, the platform results show that the deviation between the deterministic outcomes and the simulated ones are a good indicator when dealing with projects with minimal tolerance for possible imposed mitigation strategies (e.g. round-the-clock projects). Research limitations/implications The validation of the approach is limited to a multi-billion dollar nuclear refurbishment case study and functional demonstration. The applicable class of projects is limited, and includes those for which failure of cost, schedule, or quality implies project failure. Originality/value It is anticipated that the proposed approach will assist with developing a realistic planning strategy by incorporating various factors and constraints under the impact of risks and uncertainty. This may lead to a more reliable determination of outcomes for round-the-clock projects.

Full textAbstract:
In Hungary, public water facilities - drinking water works and wastewater disposal and treatment plants - are operated by companies with a valid water utility licence. During operation, the operator must ensure an organised working schedule, on-call and stand-by service which, in addition to a continuous and reliable service, enables it to intervene immediately in the event of a fault in order to remedy or mitigate operational and environmental damage and to restore service as soon as possible. In many cases, these unplanned interventions can be classified as work with boarding, such as work in manholes or pipelines, repair operations on hydroglobuses (water towers), or even unplanned interventions in waterworks reservoirs. In the course of our work, we summarise the regulation of boarding work in Hungary. We describe the possibilities of employer measures that are part of the regulation. We also compile a list of the most common operations in the water utilities sector and the dangers of boarding, which can be of great help to both those who authorise boarding and those who carry it out.

Full textAbstract:
Effective task scheduling in human-robot collaboration (HRC) scenarios is one of the great challenges of collaborative robotics. The shared workspace inside an industrial setting brings a lot of uncertainties that cannot be foreseen. A prior offline task scheduling strategy is ineffective in dealing with these uncertainties. In this paper, a novel online framework to achieve a resilient and reliable task schedule is presented. The framework can deal with deviations that occur during operation, different operator skills, error by the human or robot, and substitution of actors, while maintaining an efficient schedule by promoting parallel human-robot work. First, the collaborative job and the possible deviations are represented by AND/OR graphs. Subsequently, the proposed architecture chooses the most suitable path to improve the collaboration. If some failures occur, the AND/OR graph is adapted locally, allowing the collaboration to be completed. The framework is validated in an industrial assembly scenario with a Franka Emika Panda collaborative robot.

Full textAbstract:
While the primary goal of this symposium is to demonstrate the utility of psychophysiological measures in the evaluation of work schedules, the more general goal is to promote the use of psychophysiological measures in organizational design and management research. There are several good reasons to include psychophysiological measures in ergonomic evaluations. Foremost among these is that the information provided about worker well-being and performance capabilities cannot be obtained in other ways. Psychophysiological measures provide continuous, non-invasive, and objective measurement of an individual's response to work activities. Because of known relationships between physiological mechanisms and behavior, work-induced changes in physiological response can be used to monitor the effects of organizational design on work demand or recovery. Most would agree, however, that psychophysiological measures are seldom meaningful unless they are collected and analyzed in conjunction with other measures. In particular, psychophysiological measures can provide crucial information about worker well-being when subjective reports of distress or discomfort are biased by psychosocial factors, and also when workers compensate for increases or decreases in work demand by drawing on reserve capacity. In cases where performance measures or subjective reports are more reliable, measurement of psychophysiological responses can provide convergent results that add to the scientific validity of the research investigation. This explains why all researchers in this symposium use a balanced approach and analyze performance and/or subjective ratings in combination with psychophysiological measures. Beyond the scientific rationale for including psychophysiological measures in ergonomics research, many of the practical difficulties researchers faced in the past have been eliminated by recent technological advances. Modern heart rate monitoring systems, for example, have noise suppression features that improve signal quality and allow data collection in real work settings. Portable data loggers enable researchers to monitor multiple physiological response measures over 24-hour periods. Handling large data sets is no longer a problem because the digital storage capability of small computers is nearly unbounded. Data analysis software, such as time series analysis, has become more sophisticated and easier to use. What all this means in practical terms is that it is no longer necessary to dedicate a major portion of one's career to surmount the technical problems associated with psychophysiological research. The wide range of work scheduling topics covered in this symposium is a good example of the utility of psychophysiological measures in ergonomics research. Specific work scheduling topics include: appropriate rest break length at different times of the work day to ensure adequate recovery from sustained cognitive demand (Boucsein and Thum), methods for verifying the health and safety of underground miners working 12-hour shifts in shortened work weeks (Duchon and Smith), the impact of self-managed rest breaks on well-being during continuous computer work (Henning, Callaghan, Guttman, and Braun), and how assessing work efficiency during a cognitive task can be used to evaluate the effectiveness of work/rest schedules (Meijman). While the specific goals of these studies may differ, in each case the use of psychophysiological measures enhances the scientific validity of the research and provides important information about the relationship between work schedule design and worker well-being.

The purpose of this study is to adapt the STSIS Scale to Turkish and to investigate its psychometric qualities. The scale comprises 22 items and three variables (self-silencing, divided self, and putting the teacher first).The study participants comprised 298 young adults with a mean age of 21.09 years. Utrecht Work Engagement Scale-Student Form, Negative Affect Schedule, and Perception Form for Life Skills were used to evaluate the scale's criterion validity. The construct validity was investigated using confirmatory factor analysis. In addition, test-retest and internal consistency coefficients were examined to evaluate the scale's reliability. The Turkish version of the scale consisted of three subdimensions related to the Negative Affect Schedule and Perception Form for Life Skills. In addition, reliability values for the scale were satisfactory. The internal consistency coefficient was .89, the composite reliability was .97, and the test-retest validity coefficient was .86. According to these findings, the Turkish version of the STSIS Scale is a valid and reliable tool for use with young adults.

Full textAbstract:
The work has a dual purpose (1) to know satisfaction in BPE-CLIL (Bilingual Physical Education in Content and Language Integrated Learning) and (2) to know if students’ satisfaction can be conditioned by gender and/or age. A non-linguistic discipline as Bilingual Physical Education assumes that it is necessary to take into account objectives of two types (contents and linguistic) and students’ satisfaction has a fundamental role. A quantitative analysis is done using a Sport Satisfaction Instrument (SSI) to collect data from Primary Education learners under a CLIL methodology. The questionnaire has been validated for bilingual Physical Education in Spain and it was applied to 350 students (5th and 6th grades of Primary Education) belonging to bilingual schools in the autonomous community of Castilla-La Mancha. It is a strong and reliable instrument since the internal consistency has indicated a high Cronbach's alpha regarding fun and boredom. Satisfaction indexes have been different regarding age and not regarding gender in Bilingual Physical Education in Primary Education.

Full textAbstract:
The quality of data and its sensing cost is the important concern for task allocation in crowd sensing. The sensing capabilities of a device to send the collection of sensor data to a cloud requires crowd sensing in order to receive reliable data. Crowd sensing is used in many areas such as traffic monitoring, smart cities, health care, transportations, environmental monitoring and many more. Most of existing works are only based on assumptions in task scheduling about the number of candidate users and are mainly performed optimization of single task allocation. If the candidate users are few, then the completion of task with in the schedule can be difficult for many sensor applications. In this work, we proposed a social network-based task allocation scheme for the optimization of multi task allocation. The main idea of the proposed work is to maximize the task completion within the allocated schedule. It is evident that the task scheduling algorithms are NP-hard and we introduced a decreasing threshold task allocation (DTT) and fast greedy selections (FGS) algorithms along with Crow COOT Foraging Optimization (CCFO) algorithm to allocate the tasks parallelly with maximum efficiency. The proposed algorithms such as C-DTT (CCFO-DTT) and C-FGS (CCFO-FGS_ are used for the efficient allocation of tasks. The combination of these algorithms can be helpful in selecting the candidate users who will perform the completion of maximum tasks. Due to the selection of proper users in each round, the time consumption of the tasks to be completed is greatly reduced. The experimental results also indicates that the proposed work performs well in the optimization of multi task allocation than the other state of the art models.

A program for refining the energy spectra of neutron radiation in the neutron trap, core and reflector of the SM-3 reactor after modernization using the certified equipment and verified methods is presented in the article. The relevance of the article lies in familiarization with the experimental implementation of the methods in order to compare the experimental neutron-physical characteristics of the reactor before and after the last reconstruction. During the program creation, the previous experience of spectrometric measurements was taken into account, as well as experiments were carried out under conditions close to those of spectrometry after reconstruction. The results of the research are necessary for the planning of irradiation experiments and verification of calculation methods for determining the neutron-physical characteristics. The results of the described researches cover most science and technology areas, many aspects of human practice, including healthcare. The authors presented results of accompanying experiments, which made it possible to work out the regulations and features of short-term measurements. The developed and optimized program of neutron spectrometry in the SM-3 reactor channels will allow to obtain reliable information on the density of neutron fluxes for the first time after modernization to verify analytical data and to optimize the use of the SM-3 reactor facility to increase the production of transplutonium elements and radionuclide products.

Objective: The aim of this project was to develop an appropriate and valid instrument for assessment by medical professionals in Japanese palliative care settings.Methods: We developed a Japanese version of the Support Team Assessment Schedule (STAS-J), using a back translation method, and tested its reliability and validity. In the reliability study, 16 nurses and a physician who work in a palliative care unit evaluated 10 hypothetical cases twice at 3-month intervals. For the validity study, external researchers interviewed 50 patients with matignancy and their families and compared the results with ratings by the nurses in the palliative care unit.Results: Our results with hypothetical cases were: interrater reliability weighted κ = 0.53–0.77 and intrarater reliability weighted κ = 0.64–0.85. In the validity study comparing nurse evaluations and the results of interviews with patients and families, complete agreement was 36–70%, and close agreement (±1) was 74–100%. As a whole, weighted κ were low: between −0.07 and 0.51. Our results were similar to those in the United Kingdom and Canada.Significance of results: Although this research was conducted under methodologically limited conditions, we concluded that the STAS-J is a reliable tool and its validity is acceptable. The STAS-J should become a valuable tool, not only for daily clinical use, but also for research.

Full textAbstract:
As railroad infrastructure becomes older and older and rail transportation is developing towards higher speed and heavier axle, the risk to safe rail transport and the expenses for railroad maintenance are increasing. The railroad infrastructure deterioration (prediction) model is vital to reducing the risk and the expenses. A short-range track condition prediction method was developed in our previous research on railroad track deterioration analysis. It is intended to provide track maintenance managers with two or three months of track condition in advance to schedule track maintenance activities more smartly. Recent comparison analyses on track geometrical exceptions calculated from track condition measured with track geometry cars and those predicted by the method showed that the method fails to provide reliable condition for some analysis sections. This paper presented the enhancement to the method. One year of track geometry data for the Jiulong-Beijing railroad from track geometry cars was used to conduct error analyses and comparison analyses. Analysis results imply that the enhanced model is robust to make reliable predictions. Our in-process work on applying those predicted conditions for optimal track maintenance scheduling is discussed in brief as well.

Full textAbstract:
IEEE 802.15.4e time-slotted channel hopping (TSCH) is one of the most reliable resources of the Industrial Internet of Things (IIoT). TSCH operates on the slot-frame structure consisting of multiple channel-offsets and multiple slot-offsets. It is gaining acceptance due to its simple architecture and consume low power in industrial applications. The performance of TSCH is mainly dominated by the media access control (MAC) mechanism, which covers the refitment, enumeration, composition, and data transmission. However, in many cases, the data transmission schedules are not accurately prescribed. Therefore, most researchers are trying to define many pragmatic scenarios of scheduling. Their fundamental approach is to schedule TSCH network in a centralized way while framing scheduling based on network performance such as throughput and delay. In this work, a deep learning (DL)-based scheme has been proposed. TSCH network schedules for links to cell assignment of a slot-frame can be constructed as a maximum edge weighted bipartite matching approach. In this paper, we design bipartite edge weight to be composed of throughput and delay, and we use the Hungarian algorithm for proper cell assignment. With the Hungarian scheduling algorithm, we generate the training data and train a deep neural network (DNN) accordingly. In the simulation, we consider a simple TSCH network with 5 nodes where 12 links are formulated, and we consider 16 cells for the link assignment. The simulation results show that the proposed deep learning-based scheduling scheme can provide performance similar to the Hungarian algorithm-based scheduling scheme with above 90% accuracy and nearly 80% execution time reduction.

Full textAbstract:
The study of olive trees water requirements allows a better water management by using more accurate methods including maximum parameters of the continuum soil-plant- atmosphere. The Penman-Monteith equations is consideredas the most rational approach and the most reliable for calculating evapotranspiration. Only this approach necessarily requires an important number of climate parameters. The use of other equations, less complicated and using less climate parameters may be a reliable and efficient alternative. This experimental study was carried out on two cultivars cv. "Meski" and cv. "Chemlali" conducted in the intensive system in different bioclimatic stages (Subhumid, Semi-Arid and Arid) in Tunisia. This work aims to estimate olive trees water needs using evapotranspiration calculation in three different bioclimatic stages. For that, we compared the Penman-Monteith formula with Blaney-Criddel, Hargreaves-Temperature, Hargreaves- Radiation and Priestley-Taylor formulas to estimate reference evapotranspiration (ET0). Results show that ET0 values calculated by Priestley-Taylor and Blaney-Criddel formulas were more or less similar to Penman-Monteith. The ET0 values found by Hargreaves-Temperature and Hargreaves-Radiation were twice the values calculated by Penman-Monteith formula. We also found good correlations between the reference evapotranspiration calculated by the Penman-Monteith equation and that calculated by Priestley-Taylor and Blaney-Criddel equations in all bioclimatic stages (R2 more than 0.85, p < 1%). The ET0 sensitivity analysis has shown that solar radiation and air temperature (energetic climatic parameters) have the dominant effect on the ET0 at the level of the different climatic regions. Accordingly, in the case of lack of some climatic parameters and in sub-humid, semi-arid and arid conditions and for the different phenological stages of the olive tree, we can use Priestley-Taylor and/or Blaney-Criddle formulas to estimate water needs.

Full textAbstract:
Background: The World Health Organization Disability Assessment Schedule (WHODAS-II) is a widely used generic assessment instrument for health and disability. However, a specific psychometric evaluation for this scale in multiple sclerosis (MS) is lacking. This study is aimed at the assessment of the psychometric properties of the WHODAS-II in MS with Cronbach’s α and modern Rasch-model analyses. Methods: The WHODAS-II was administered to 136 consecutively recruited MS patients. Several indexes of fit to the Rasch model were evaluated in order to assess internal construct validity. Internal consistency was assessed with Cronbach’s α and the Person Separation Index (PSI). External validity was evaluated by analyzing correlations between the WHODAS-II and the Multiple Sclerosis Quality of Life-54 (MSQoL-54). Results: Classical reliability indexes (Cronbach’s α and intraclass correlation) showed good to excellent reliability for most of the subscales and for the total scale (α = 0.93). The total scale both with (36 items) or without (32 items) work items reached good fit to the Rasch model (PSI = 0.83). However, analysis of the subscales could resolve only four subscales out of seven. Conclusions: The WHODAS-II is a reliable and valid instrument for the assessment of patient-reported disability in MS, with some limitations including some item redundancy and questionable reliability of some subscales.

The questionnaire was online accessible for a 45-day period (15/8-30/9/2020).Results:The responses of 503 adult people with RD (M/F/NA 94/408/1), were available for analysis. Their age was stratified in decades (18-20 0.6%,21-30 5.99%, 31-40 22.36%, 41-50 38.92%, 51-60 22.16% and over 60 9.58%); totally, 83.44% were in the “work-reproductive” period. The predominant RD types were RA 30.3%, SLE 22.8%, AS 20.2% and PsA 20.2%, respectively. Nearly 90% were on medication, namely 40% on biologics, 33% on methotrexate (as a monotherapy or combined therapy), 16.2% on steroids. A minority were either on alternative therapies (2.8%) or off medication (7.5%), respectively. Most of the people were still employed (72.9%) on a full-time schedule (57.7%) and 4.8% on a part-time one, due to their RD. The rest of them (27.1%) were out of work either due to RD (17%) or retirement (1.7%) or for unrelated to the RD reasons (8.4%). The main source of financial income was personal work (52.4%), followed by a family member support (31.1%), while 11% had either a state pension (8%) or a subsidy (3.2%). In respect to the daily house-keeping, half of them (59.3%) had a varying difficulty (mild 36.3%, severe 23%) and 0.8% considered themselves as “unable”. The diagnosis was mostly established (81%) prior to the work onset. Post-diagnosis, RD had not affected their working schedule in 47.2%, 17% continued to work with respective adaptations but 30% had quitted or resigned from their work 1-7 years later. RD was notified to the work environment by 85%. As for a compassionate work management, 46% reported no change, 28% an improved policy but 28% a worse one. The development of relative adaptations in the work setting (as chairs, devices, flexible schedule) were considered as favorite factors easing the work by 85%. 17% reported an employer’s knowledge on RD related working legislation, 43% the contrary and another 38.7% wished for a future employer’s awareness. Most of the participants (58.9%) had no personal information on this field but were eager to get it. The uneventful impact of RD on finding or keeping a job was registered by 77.4% and 66.9%, respectively. During COVID, most of the participants (53%) have not asked for an RD-related leave and only 24.2% chose to telework, a policy that raised mutual satisfaction in 19%. Of note, the working conditions have not mainly been altered (67%) after the end of the 1st quarantine.Conclusion:This study highlighted that although RD predominate in females, women are more willing to participate in such projects (F 90%). The financial income was mainly based on a personal or a family member work reimbursement (83%), while 11% depended on a state pension or subsidy. The majority has notified the RD to their work environment (85%) while another 85% considered as favorite factors easing the work, several adaptations in the work setting such as chairs, devices, flexible schedule etc. Interestingly, 60% of the participants were unaware of the beneficial legal work rights and nearly 70% of them believe that RD is an obstacle for employment or working maintenance. COVID has not dramatically impaired their work life although the use of teleworking should be strengthened.Disclosure of Interests:None declared.

Many of the tasks involved in looking for a job these days involve sharing and storing digital data. Digital technology is now required for job seekers to research employers, store resumes, complete applications, and schedule interviews. What is the employment process for people who are living on the poverty line, without reliable access to the Internet or mobile phones? We focus on technology maintenance, the continuous work required to stay digitally connected, to understand how low-income job seekers in northern California manage the circulation and storage of information. We incorporate the concept of delegation from Latour to explore how people consciously consider who or what entities are responsible for technology maintenance, as this varies by government policies related to digital subsidies. This article draws novel connections between the influence of government policy on technology maintenance and how both the policies and digital inequalities shape impoverished job seekers’ choices around sharing and storage practices.

Abstract Over the last decade the number of studies on public transit accessibility has significantly increased. The aim of the study was to analyse the scope of application of measurements of the dynamic time accessibility in transportation systems for evaluation purposes. It was assumed that the indicator is a feasible measure for basic analysis however additional indicators are needed for reliable assessment. The study included assessing access to the global centre of Warsaw and to local and district centres in particular units. Public transit accessibility was analysed using schedule-based travel time and the population data statistic. The results of the study confirm the dynamic character of public transit time accessibility and its usefulness as a measure. Spatial and transit barriers were identified in local distribution centres and public transit operation. The work presented in the paper highlights the relevance of the in-depth evaluation of the public transit system in relation to the major congestion problems in Warsaw.

The management of oil-product pipelines represents a critical task in the daily operation of petroleum supply chains. Efficient computational tools are needed to schedule pipeline operations in a reliable and cost-effective manner. This work presents a novel discrete event simulation system for the detailed scheduling of a multiproduct pipeline consisting of a sequence of pipes that connects a single input station to several receiving terminals. The pipeline is modeled as a non-traditional multi-server queuing system involving a number of servers at every pipe end that perform their tasks in a synchronized manner. By using alternative priority rules, the model decides which server should dispatch the entity waiting for service to the associated depot. Also, the model deals with the timely fulfillment of terminal demands and the system response to unexpected events. In combination with optimization tools, the proposed simulation technique permits to easily manage real-world pipelines operations with low computational effort.

This paper describes how AI is used to plan, schedule, and optimise nightly engineering works for both the commuter and rapid transit lines in Hoag Kong. The MTR Corporation Limited operates and manages all the rail lines in Hong Kong. Its Engineering Works and Traffic Information Management System (ETMS) is a mission critical systemthat manages all information related to engineering works and their related track possessions and engineering train movements. The Al Engine described in this paper is a component of this ETMS. In Hong Kong, the maintenance, inspection, repair, or installation works along the rail lines are done during the very short non-traffic hours (NTH) of roughly 4 to 5 hours each night. These engineering works can be along the running tracks, track-side, tunnel, freightyards, sub-depots, depot maintenance tracks, etc. The proper scheduling of necessary engineering works is crucial to maintaining a reliable and safe train service during normal hours. The Al Engine optimizes resource allocation to maximize the number of engineering works that can be performed, while ensuring all safety, environment, and operational rules and constraints are met. The work described is part of a project to redesign and replace the existing ETMS, deployed in 2004 with an updated technology platform and modern IT architecture, to provide a more robust and scalable system that potentially can be deployed to other cities around the world.

Abstract Introduction While up to 52% of heavy vehicle crashes are drowsiness-related, the contributions of schedule factors to real-time objective drowsiness in heavy vehicle drivers (HVDs) have not been studied. Eye-blink parameters are a reliable indicator of driver drowsiness. This study aimed to examine the relationship between work-related factors and objective drowsiness in HVDs. Methods HVDs (all males, aged 49.5 ± 8 years) undertook 5- weeks of sleep-wake monitoring (Philips Actiwatch, N=15), and 4-weeks of infrared oculography (Optalert, Melbourne, Australia) to monitor their eye-blink parameters (averaged each minute) while driving their own vehicle (N=12). Participants slept for 5.75± 1.4 hours before the drives. Drowsiness events were defined as any Johns Drowsiness Scores (JDS) scores larger than 2.6 based on prior research. The relationships of schedule factors and drowsiness events per hour were assessed via mixed linear regression models. Results Drowsiness event rates were 3–5 times greater between 22:00 and 03:00 hours compared to between 16:00 and 17:00 hours (17- 25 events/h vs 5 events/h, P= 0.0001 to 0.007). The frequency of drowsiness events at night varied with shift start time and time into shift (P= 0.0001 to 0.001). Compared to the first hour of driving, drowsiness event rates rose significantly during the 13th to the 21st hours into the shift (13- 59 events/h vs 5.5 events/h, P= 0.0001 to 0.007). During sequential night shifts drowsiness events were 1.8 times more common compared to 1–3 sequential day shifts (9 events/h vs 5 events/h, P= 0.012 to 0.019). Conclusion Driving at night, for more than 12 hours and sequential night shifts increase real-time drowsiness in HVDs, with these factors interacting resulting in even higher rates of drowsiness events. Longitudinal studies in larger populations will further define how these factors interact to inform the work scheduling of HVDs to reduce the risk of drowsiness. Support This research was supported by the CRC for Alertness, Safety and Productivity.

e18073 Background: Electronic Medical Records (EMR) were born as a result of medicine digitalization. Healthcare information systems (HIS) hold great value to the workflow management and patient care. New technologies not only allow us work with a faster and more reliable medical history, but also understand how health professionals think and work. Time consumption is one of the biggest issues that geriatric assessment (GA) has to deal with. Hurria et al. developed a brief tool which requires minimal resources and time spent (≈30 mins) by healthcare providers. On the other hand, patients´ medical history review, writing reports or tumor board discussions are often underestimated on daily time schedule. The aim of this study is to analyse the effective working time (EWT) invested in geriatric assessment in our centre by Big Data analytics. Methods: From 1 March 2018 to 31 december 2018, > 70 years-old patients were prospectively recruited from the outpatient oncology practices at Basurto University Hospital. Nurse-guided geriatric assessment was scheduled 45 mins before oncologist’s first visit, and functional status, comorbidity, cognitive function, psychological state, social support, polypharmacy, nutritional status, and nurse interventions were measured. Patterns of nurse and medical behaviors from EMRs were tracked. The model to figure out active behaviour in HIS was defined as > 23 events/hour. EWT was established as time spent between first and last access to HIS. Isolated events and interventions by users other than oncologists and nurses were excluded. Results: 280 patients were enrolled, 54.3% men. Geriatric assessment detected: cognitive impairment 17 pts (6.9%), mental health alteration 78 pts (27.8%), Poor social support 10 pts (3,7%), polypharmacy 239 pts (89,28%), and severe malnutrition 34 pts (13.2%). Nurse specific intervention was made in 90 pts (32,6%). The median EWT by nurses for a GA was 39 minutes (SD 0:21), and 46 mins (SD 0:17) by oncologists´global evaluation. Nurses started in average 3 mins (SD 0:27) before scheduled visit, and oncologists 9 mins (SD 0:28) after. Conclusions: Big data analytics show an assumable effective working time for a geriatric assessment in our patients. HIS users behavior analysis could help in the management of our healthcare systems.

Abstract Construction progress tracking and monitoring is a complex process that is crucial for the successful execution of projects and the delivery of a high-quality product to the client. However, these tasks remain mostly manual - time-consuming and error prone, which often leads to suboptimal quality, cost and schedule overruns. The present research proposes the use of an autonomous rover for the data collection from construction site. The objective is to create a hybrid data processing system using point clouds from the Simultaneous Localization and Mapping (SLAM) algorithm used for robot navigation, and beacons’ data integrated with BIM, to track construction progress and provide project managers with reliable information in quasireal time. The paper is composed of four parts: first, a literature review of best practices regarding the technology used for progress tracking is performed. Second, we propose a framework for automated data collection and information processing for automated progress tracking and monitoring. Third, we present a real-world case study partially implementing the framework by using data acquired by an autonomous rover and BIM, and simulate a real-time reconstruction of the construction site status. Finally, the results are discussed, and future work is identified.

The purpose of the study was to establish the effects of teachers’ collegiality on learners’ academic performance in public secondary schools of Baringo North Sub-County, Kenya. The study employed mixed methods approach which utilized questionnaires and interview schedules. It adopted a descriptive research design in carrying out the study. The target population comprised 27 principals and 216 teachers in the 27 public secondary schools of Baringo North Sub County. A simple random sampling technique was used to select 138 teachers while 24 principals were purposively selected. From these populations, two schools were selected to pilot the research tools where a reliable Cronbach’s Alpha coefficient of 0.77 was obtained upon computation. Validity of the research instruments was carried out by the University supervisor and necessary revision done. Questionnaires were used to collect quantitative data from teachers while interview schedule was used to collect qualitative data from principals. Quantitative data were analysed to obtain means, percentages, and standard deviation. Qualitative data on the other hand were analysed and presented thematically alongside the quantitative data. Inferential statistics were run to test the null hypothesis using Pearson’s Linear Correlation Coefficient. The findings established that teachers’ collegiality influences learners’ KCSE academic performance in public secondary schools of Baringo North Sub-County. However, there was a weak positive correlation between teachers’ collegiality and learners’ academic performance. It also established that though collegiality was not fully practiced there was a strong synergy among teachers to improve learners’ performance. The study recommends that teachers need to be supported by headteachers to collaborate to offer the best services to their learners and create more meaningful work. School headteachers should enhance teamwork among teachers to perform their best and staff members should meet or interact regularly, share ideas and expertise to attain higher performance.

In regulated environments, which have impacts on the society, standards are adopted to determine rules to be followed, since the society expects to receive safe and reliable products and services. Regulatory agencies usually require adherence to requirements established in norms and standards so the product can be approved. In this context, space programs Quality Assurance standards are applicable to satellite projects with a wide responsibility range, from experimental small satellites to manned spaceships. Applying the full contents of these standards may be unfeasible to small missions with low responsibility, considering the cost and schedule constraints inherent to this type of project. Therefore, a customization of the requirements must be conducted in a thoughtful and disciplined manner, considering the project characteristics. The tailoring process presented in this work includes the analysis of the risk to the mission due to the reduction of the set of requirements. Each requirement was evaluated in view of its maintenance, modification, or elimination. This paper presents a process of tailoring mission-specific requirements, using a mission risk rating and the risk analysis tool FMECA. The result was a structured process for tailoring requirements, which provided a subset of Quality Assurance requirements applicable to small satellite projects.

Trust/Mistrust in God have turned out to be two constructs that have great relevance in the study of the relationship between religion, spirituality, and health. In Spain, there are no instruments adapted to measure trust/mistrust in God, which limits the work of researchers interested in these aspects. Therefore, the aim of this study was to validate the Brief Trust/Mistrust in God Scale (BTMGS) in Spanish. The scale translated into Spanish was applied in a sample of 178 oncologic patients together with the Positive and Negative Affect Schedule (PANAS) and the significant others subscale of the Multidimensional Scale of Perceived Social Support, due to the existing evidence of relationships between the variables evaluated by these measures. Internal consistency, structural validity, convergent and discriminant validity were evaluated. The Spanish adaptation of the BTMGS obtained high internal consistency, both for trust subscale (α = 0.95) and for the mistrust subscale (α = 0.86). Furthermore, the correlations found between the BTMGS and the measures of positive and negative emotions and social add evidence of convergent and discriminant validity. These results suggest that the Spanish version of the BTMGS is a valid and reliable measure to be used in research on religion, spirituality and health in Spanish-speaking contexts.

Make-to-order production needs flexibility, quality and synchronicity of planning. Numerous types of products and complex control parameters lead to high requirements for safety, stability and continuity of the production process, as well as strict requirements for instant production management. The need for a high reaction rate to changes in the production system, adaptability and traceability, must be ensured by methods of accurate and reliable control and management of production. The most difficulty is the stage of making a schedule for make-to-order multi-nomenclature productions. Existing systems of scheduling are often not connected in real time with the current production process, all this leads to a high level of unfinished orders. It is necessary to take a new look at the existing planning systems and search for an approach with the possibility of analyzing and optimizing the operational and production plan, taking into account the actual implementation of the provided production process. The research is aimed at developing a synchronous scheduling method suitable for a multi-nomenclature make-to-order production with a variable number of products, and designed to reduce order fulfillment time, reduce inventory and improve work efficiency by adapting to fluctuations in production and product life cycle and implementing an optimal production plan.

Full textAbstract:
The methodology of development of building project schedules, proposed in the article, is based on an attempt to combine two independent approaches in order to increase the probability of fulfillment of time limits planned in the CPM schedules during the performance of construction works. The analysis of the risk associated with the planned building project will allow for the determination of those tasks which are most threatened by the exceeding of the planned duration time. The application of time buffers, their proper location in the schedule and the determination of their duration, taking into account the expected risk of delays, allow to develop the schedules that contain the appropriate time reserves to compensating for the possible delays. Such a schedule may serve not only as a reliable basis for the determination of the expected deadline for completion of construction works, but also for the management of these works during performance. Selected components of MOCRA and MP-KP methods were proposed in the article.

Full textAbstract:
Construction projects have faced serious schedule delays caused by rework risks. However, it appears that traditional methods are of limited value in developing applicable project schedules. This study presents an analysis on construction projects schedule development under rework scenarios by a novel method named the improved critical chain design structure matrix (CCDSM). Research data are collected from a real estate development project in China. As a result, predictions of project completion duration and probability have been made. A reliable schedule considering information interactions has been developed and visualized. Rework impact areas of activities have been examined to quantitatively record the impact on project duration. To meet different demands, the method generates two more schedules setting different rework buffers. Furthermore, these activities have the potential of causing rework and have been quantified based on the calculation of two criticalities, providing an identification of rework-intensive works that should be payed close importance to, which have not be realized by previous methods. The results proved the feasibility and effectiveness of this method in developing a schedule for construction projects disturbed by rework, helping practitioners adopt measures to avoid rework-caused schedule delays and achieve sustainable development of such projects.

Full textAbstract:
Abstract Chandra Asri, the largest integrated petrochemical company in Indonesia, requires a reliable electrical system to ensure production. Electrical power was supplied by the grid from PT. PLN through a 150 kV system in parallel with captive generation. The electrical system uses the Emergency Shutdown System (ESD) to protect against various disturbances that can cause equipment damage and work accidents. ESD will only work if things happen according to a logic diagram that has been designed according to the needs. One time, there was a power outage due to the active ESD. This causes huge losses for the company. The results of the investigation showed that there were no disturbances to either the grid or the captive generator. It is suspected that there is a false signal that causes the ESD to activate from the DC charger signal. For this reason, efforts are needed to eliminate the possibility of this nuisance signal occurring in the future by redesigning the logic and signal source of AC power failure by considering the existing secondary selective electrical system. Modification of the ESD system is carried out in 5 stages, namely 1) fault analysis, 2) modification of logic diagram design, 3) system development, 4) testing, and 5) evaluation. The results of the redesign decided that modifications should be made to the ESD system and carried out on the next Turn Around Maintenance schedule because this modification requires an offline electrical system. The analysis and simulation results show that the ESD system is safe against similar disturbances. It is hoped that the redesign and modification of the ESD system can prevent signal interference in the AC Power Failure Signal.

Purpose: With this work, we intend to promote research on the application of Operations Management tools in order to assist with decision-making in health crisis situations. During the first six weeks of the COVID-19 crisis in Spain, we have contacted a large number of hospital and health department managers in the Valencian Community and other regions of Spain. The result is that very few, at least when contact was made and at the time of writing this article, had consulted staff members in the Operations Management area for advice on this situation, and they are quite reluctant to do so. This is in spite of the fact that some medical sources also consider this crisis to be one of resources, not merely a medical crisis. Our opinion is that Operations Management can make a useful and valuable contribution to anticipate and improve the management of scarce resources, even in times of crisis. If those responsible for public health or heads of hospitals do not see this usefulness, then there is a huge gap between research and practice in Operations Management and what is transmitted to the healthcare sector. Our aim is to help reduce this gap.Design/methodology/approach: In the first part of the article, we will justify that this crisis, besides being a medical crisis, is also a crisis in terms of resources. We will briefly review some of the Operations Management tools that we believe are appropriate for managing this crisis. We will focus on those that we will illustrate in the second part of the article as a practical example of the action research protocol (only the action planning phase), in which we are currently involved.Findings: Due to the peculiarities of the COVID-19 epidemic, it is reasonable to think that the evolution and duration of each outbreak, and the way it is dealt with, will be different in each hospital and/or each health department. Anticipating the number of patients who will require care and forecasting the consumption of resources over time is complex, due to the long and variable incubation times and the uncontrolled evolution of the treatments needed by each patient. Furthermore, since the evolution of new patient admissions is not homogeneous, the forecasting of requirements is difficult. Providing real-time support and detecting with a certain degree of anticipation the potential levels of demand for health care will enable hospitals to define what stages of the contingency plan to apply and how to (re)assign the available resources in the most efficient way possible.Research limitations/implications: Hardly any current data are available, not only publicly, but also through public health ministries and managers; those that are available are not very reliable and come from studies with non-representative samples. For this reason, all forecasts must be taken with a note of caution, and in particular, designing review mechanisms every time a new set of updated reliable data becomes available (something that occurs on a weekly basis).Originality/value: In this work, we will show an example of a proposal for the practical application of Operations Management tools. Our proposal may be useful to hospital managers and public administrators in the healthcare sector (regional ministries or their equivalents). Each health department, hospital or hospital group will generate the aggregate data that facilitate the calculation of needs as input parameters for the model (available and occupied beds, daily admissions, mean lengths of stay in each healing phase and the percent of patients who evolve from one stage to another in the progression of the disease/healing process) and will be able to analyze how the system responds and evaluate different strategies or mitigating actions. These tools have been shown to be useful and reliable in manufacturing and service contexts that show a strong seasonal demand (both occasional and recurring) requiring a great deal of resources. We believe these situations are analogous to those faced by hospitals and the healthcare system in an epidemic like COVID-19. With them, we could facilitate the aggregate planning of resources for hospital administrators in order to provide them operational support during the COVID-19 contingency plan. However, the array of useful tools for this crisis is not limited to those that we will illustrate. Our intent is to encourage the Operations Management academic community to demonstrate how they contribute to the service of society in this COVID-19 epidemic, providing knowledge that can be extrapolated to other similar situations in the future that we may be unfortunate enough to experience.

Purpose Resilience is defined as the ability to face adversities with positive outcomes. Various scales have been utilized, including 25-item Connor-Davidson Resilience Scale (CD-RISC), to evaluate resilience among populations. Resilience research is scarce, particularly in Lebanon as no such scales have been validated. Thus, in the present work, we aimed to assess the psychometric properties of the Arabic version of CD-RISC. Patients and methods The study was conducted at the Women’s Health Center at the American University of Beirut Medical Center among Lebanese women presenting to the obstetrics and gynecology clinics. Internal validity of the Arabic CD-RISC was examined. Pearson’s correlation coefficients between the scores of the Arabic version of CD-RISC and the other related constructs (Rosenberg Self-Esteem Scale, Dispositional Hope Scale, Life Orientation Test, and Positive and Negative Affect Schedule) were assessed to evaluate its divergent and convergent validity. We collected responses from a total of 63 Lebanese women. Results The studied scale displayed a high internal consistency. Adequate correlation coefficients were manifested by the significant positive moderate to strong and negative moderate correlations between the Arabic CD-RISC and the other related constructs. Conclusion This is the first study to validate the Arabic version of the CD-RISC in a sample of Lebanese women. The findings of this study provide evidence that the Arabic version of CD-RISC is a reliable and valid tool for the evaluation of resilience among Lebanese women.

Full textAbstract:
The problems of managing complex project management systems are associated with numerous parameters that characterize their state. Most modern methods of forecasting project activity are based on the use of statistical modeling of individual processes and tools, for example, a work schedule, which requires both the justification of the adopted laws for the distribution of random work durations and the planning of a certain organizational and technological sequence of work. The collection and processing of data on all parameters is a complex and expensive procedure, and a complete justification of all project characteristics can lead to the information complexity of the system under consideration. However, it is impossible to refuse this due to the need to obtain relevant and reliable data for the adoption and implementation of management decisions. Thus, it is necessary to look for ways and means to reduce the number of controlled parameters, create algorithms that allow predicting the presence of undesirable processes in a controlled system, and develop recommendations for a more detailed analysis of individual project management subsystems. To overcome the informational complexity of predictive models, it is proposed to use a phenomenological approach that is associated with the definition of entropy, which allows using a minimum of information about the planned and updated course of the project. The concept of entropy is one of the key concepts of thermodynamics and information theory, and also finds its application in a number of other sciences, the subject of research and study of which are complex stochastic systems. The possibilities of using entropy and entropy modeling are currently being actively explored in the theory of project management. The paper considers an entropy approach to modeling project management systems, in which, on the basis of mathematical procedures arising from K. Shannon's information theory, information phenomenological models are created. The IPMA ICB 4.0 standard is considered as an example. The developed tool creates the prerequisites for the effective use of the entropy approach to assessing complex economic and social systems.

Full textAbstract:
<abstract><p>In the last decades, cities have increased the number of activities and services that depends on an efficient and reliable electricity service. In particular, households have had a sustained increase of electricity consumption to perform many residential activities. Thus, providing efficient methods to enhance the decision making processes in demand-side management is crucial for achieving a more sustainable usage of the available resources. In this line of work, this article presents an optimization model to schedule deferrable appliances in households, which simultaneously optimize two conflicting objectives: the minimization of the cost of electricity bill and the maximization of users satisfaction with the consumed energy. Since users satisfaction is based on human preferences, it is subjected to a great variability and, thus, stochastic resolution methods have to be applied to solve the proposed model. In turn, a maximum allowable power consumption value is included as constraint, to account for the maximum power contracted for each household or building. Two different algorithms are proposed: a simulation-optimization approach and a greedy heuristic. Both methods are evaluated over problem instances based on real-world data, accounting for different household types. The obtained results show the competitiveness of the proposed approach, which are able to compute different compromising solutions accounting for the trade-off between these two conflicting optimization criteria in reasonable computing times. The simulation-optimization obtains better solutions, outperforming and dominating the greedy heuristic in all considered scenarios.</p></abstract>

Full textAbstract:
A power-down system has an on-state, an off-state, and a finite or infinite number of intermediate states. In the off-state, the system uses no energy and in the on-state energy it is used fully. Intermediate states consume only some fraction of energy but switching back to the on-state comes at a cost. Previous work has mainly focused on asymptotic results for systems with a large number of states. In contrast, the authors study problems with a few states as well as systems with one continuous state. Such systems play a role in energy-efficiency for information technology but are especially important in the management of renewable energy. The authors analyze power-down problems in the framework of online competitive analysis as to obtain performance guarantees in the absence of reliable forecasting. In a discrete case, the authors give detailed results for the case of three and five states, which corresponds to a system with on-off states and three additional intermediate states “power save”, “suspend”, and “hibernate”. The authors use a novel balancing technique to obtain optimally competitive solutions. With this, the authors show that the overall best competitive ratio for three-state systems is 9 5 and the authors obtain optimal ratios for various five state systems. For the continuous case, the authors develop various strategies, namely linear, optimal-following, progressive and exponential. The authors show that the best competitive strategies are those that follow the offline schedule in an accelerated manner. Strategy “progressive” consistently produces competitive ratios significantly better than 2.

The smallest of the nation's uniformed armed services, the United States Coast Guard's basic missions relate to maritime safety, mobility, and security; national defense, and natural resources protection. It is responsible for enforcement of maritime laws and marine environmental pollution response. The Coast Guard offers many career opportunities for enlisted personnel, including Marine Science Technician (MST). MSTs conduct marine-safety activities such as investigating pollution incidents and monitoring pollution clean-ups. Possible scientific duties include responding to oil and hazardous-materials spills, observing and forecasting weather. An increasing number of civilian employers are becoming more aware of the unique strengths former military personnel can bring with them to a consultant position. A consultant is someone who has expertise in a specific area or areas and offers unbiased opinions and advice for a fee. There are many reasons why the private and public sector need consultants for problem solving. One very important reason; Government regulatory compliance. Government regulations at all levels are constantly changing, and companies are frequently not prepared or trained to comply. Consultants may be retained to provide expertise to assist a company in complying economically, efficiently, and with the least amount of trauma to the organization. They can also be hired to provide in-house training to keep staff informed of new management and supervisory techniques or technical knowledge and to improve employee safety. Successful consultants often possess certain attributes. They can be identified with good physical and mental health, professional etiquette and courtesy, stability of behavior and self-confident. In addition to these skills, here are two military-related attributes that most companies find attractive and will help any organization simplify the task at hand. Loyalty to the Team. Military personnel bring with them an intrinsic understanding of how loyalty adds to team proficiency and builds trust in a work environment. For business leaders looking to make an improvement in their company, military personnel often outperform other candidates as proven team players, as demonstrated by hard work, motivation, and dedication. Reliable Work Ethic. Knowing the importance of adhering to a schedule and consistently performing well at work demonstrates professional maturity. One of the most difficult challenges to hiring professionals is being able to accurately judge candidates in these areas. Through service, training, and lifestyle, former military personnel will typically have the work ethic that any business owner would be thrilled to replicate in all of the organization's employees.

Full textAbstract:
Safety-critical automation often requires redundancy to enable reliable system operation. In the context of integrating sensors into such systems, the one-out-of-two (1oo2) sensor architecture is one of the common used methods used to ensure the reliability and traceability of sensor readings. In taking such an approach, readings from two redundant sensors are continuously checked and compared. As soon as the discrepancy between two redundant lines deviates by a certain threshold, the 1oo2 voter (comparator) assumes that there is a fault in the system and immediately activates the safe state. In this work, we propose a novel fault prognosis algorithm based on the discrepancy signal. We analyzed the discrepancy changes in the 1oo2 sensor configuration caused by degradation processes. Several publicly available databases were checked, and the discrepancy between redundant sensors was analyzed. An initial analysis showed that the discrepancy between sensor values changes (increases or decreases) over time. To detect an increase or decrease in discrepancy data, two trend detection methods are suggested, and the evaluation of their performance is presented. Moreover, several models were trained on the discrepancy data. The models were then compared to determine which of the models can be best used to describe the dynamics of the discrepancy changes. In addition, the best-fitting models were used to predict the future behavior of the discrepancy and to detect if, and when, the discrepancy in sensor readings will reach a critical point. Based on the prediction of the failure date, the customer can schedule the maintenance system accordingly and prevent its entry into the safe state—or being shut down.

Full textAbstract:
The state estimation of lithium-ion battery is the basis of an intelligent battery management system; therefore, both model-based and data-driven methods have been designed and developed for state estimation. Rather than using complex partial differential equations and the complicated parameter tuning of a model-based method, a machine learning algorithm provides a new paradigm and has been increasingly applied to cloud big-data platforms. Although promising, it is now recognized that big data for machine learning may not be consistent in terms of data quality with reliable labels. Moreover, many algorithms are still applied as a black box that may not learn battery inner information well. To enhance the algorithm generalization in realistic situations, this paper presents a fractional-order physics-informed recurrent neural network (PIRNN) for state estimation. The fractional-order characteristics from battery mechanism are embedded into the proposed algorithm by introducing fractional-order gradients in backpropagation process and fractional-order constraints into the convergence loss function. With encoded battery knowledge, the proposed fractional-order PIRNN would accelerate the convergence speed in training process and achieve improved prediction accuracies. Experiments of four cells under federal urban driving schedule operation conditions and different temperatures are conducted to illustrate the estimation effects of the proposed fractional-order PIRNN. Compared to the integer-order gradient descent method, the fractional-order gradient descent method proposed in this work can optimize network convergence and obtains regression coefficient larger than 0.995. Moreover, the experimental results indicate that the proposed algorithm can achieve 2.5% estimation accuracy with the encoding fractional-order knowledge of lithium-ion batteries.

Full textAbstract:
The residential sector is a major contributor to the global energy demand. The energy demand for the residential sector is expected to increase substantially in the next few decades. As the residential sector is responsible for almost 40% of overall electricity consumption, the demand response solution is considered the most effective and reliable solution to meet the growing energy demands. Home energy management systems (HEMSs) help manage the electricity demand to optimize energy consumption without compromising consumer comfort. HEMSs operate according to multiple criteria, including electricity cost, peak load reduction, consumer comfort, social welfare, environmental factors, etc. The residential appliance scheduling problem (RASP) is defined as the problem of scheduling household appliances in an efficient manner at appropriate periods with respect to dynamic pricing schemes and incentives provided by utilities. The objectives of RASP are to minimize electricity cost and peak load, maximize local energy generation and improve consumer comfort. To increase the effectiveness of demand response programs for smart homes, various demand-side management strategies are used to enable consumers to optimally manage their loads. This study lists out DSM techniques used in the literature for appliance scheduling. Most of these techniques aim at energy management in residential sectors to encourage users to schedule their power consumption in an effective manner. However, the performance of these techniques is rarely analyzed. Additionally, various factors, such as consumer comfort and dynamic pricing constraints, need to be incorporated. This work surveys most recent literature on residential household energy management, especially holistic solutions, and proposes new viewpoints on residential appliance scheduling in smart homes. The paper concludes with key observations and future research directions.

Full textAbstract:
(1) Introduction and Objective: Upper tract urothelial carcinoma (UTUC) is an uncommon disease, only accounting for 5–10% of all urothelial carcinomas. Current clinical practice guidelines encourage a risk-adapted approach to UTUC management, including lymph node dissection (LND) in patients with muscle-invasive or high-risk tumors. If pathological characteristics could be more accurately predicted from preoperative data, we could optimize perioperative management strategies and outcomes. The aim of this article is to present a detailed revision of preoperative predictors for muscle-invasive UTUC, locally advanced or advanced UTUC, as well as current indications, technique variations, and the reasons as to why LND should be offered to these patients. (2) Methods: We included any kind of studies related to information concerning UTUC, nephroureterectomy, LND, risk factors for recurrence, prediction tools and models for risk stratification. A literature search was conducted following medical subject headings (MeSh), Emtree language, Decs, and text words related. We searched through MEDLINE (OVID), EMBASE (Scopus), LILACS, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to May 2021. Evidence acquisition was presented according to the PRISMA diagram. (3) Results: Preoperative risk factors for either muscle-invasive UTUC (≥pT2), extra urothelial recurrence (EUR), locally advanced disease, or high-risk UTUC can either be derived from ureteroscopic (URS) findings, urine cytology, URS biopsy, or from preoperative radiologic findings. It seems reasonable that LND may provide not only staging and prognostic information but also play a therapeutic role in selected UTUC patients. The patients who benefit the most from LND appear to be those with ≥ pT2 disease, because patients with tumors ≤ pT1 rarely metastasized to LNs. UTUC has characteristic patterns of lymphatic spread that are dependent on tumor laterality and anatomical location. Choosing the right patients for LND, designing and standardizing LND templates based on tumor location and laterality is critical to improve LN yield, survival outcomes, and to avoid under-staging or overtreatment. (4) Conclusions: Patients with muscle-invasive or non-organ-confined UTUC have an extremely high risk for disease recurrence and cancer-specific mortality (CSM). Preoperative factors and prediction models must be included in the UTUC management pathway in our clinical practice to improve the accurate determination of high-risk groups that would benefit from LND. We recommend offering LND to patients with ipsilateral hydronephrosis, cHG, cT1 at URS biopsy and renal sinus fat or periureteric fat invasion. The role of lymphadenectomy in conjunction with radical nephroureterectomy (RNU) is still controversial, given that it may result in overtreatment of patients with pTa-pT1 tumors. However, a clear benefit in terms of recurrence-free survival (RFS) and cancer-specific survival (CSS) has been reported in patients with ≥pT2. We try to avoid LND in patients with cLG, cTa, and no ipsilateral hydronephrosis if the patient is expected to be compliant with the follow up schedule. There is still plenty of work to do in this area, and new molecular and non-invasive tests are necessary to improve risk stratification.

Full textAbstract:
Abstract Introduction Wearable electroencephalogram (EEG) monitoring has a remarkable potential, it is safe, scalable and can track neural signatures for long periods. One such signature is the power spectra of non-rapid-eye-movement (NREM) sleep which has been shown to demonstrate a trait-like characteristic. Changes in personalized signatures has been associated with biomarkers of Alzheimer’s disease and is of great interest for early detection and clinical management. This work investigates monitoring of signatures using a wearable device that records EEG from the ear (ear-EEG) and compares the intra- and inter-individual similarity of the neural signatures with that from central scalp-EEG. Methods We initiated a two phased in-home study, monitoring 20 subjects for 4 nights (A), followed by a delayed but continued monitoring of 10 subjects for 12 nights (B). In A, subjects wore a dry-electrode ear-EEG system and a partial PSG, in B the subjects wore only the ear-EEG system. Subjects were instructed to follow their usual time schedule and lifestyle. Sleep stages were scored manually according to AASM in A and automatically in B. The grand average power spectra of NREM2 sleep were computed and log-transformed prior to calculating the cosine similarity for determination of the intra- and inter-individual similarity. Results The ear-EEG and scalp-EEG analysis showed that mean intra-individual similarity was higher than mean inter-individual similarity. Permutation tests indicate that the observed mean difference is statistically significant p<0.01 for both montages. Comparing the distributions of intra-individual similarities for ear-EEG and scalp-EEG, the observed mean difference is statistically significant p<0.05, in favor of a more stable ear-EEG signature. Comparing ear-EEG signatures between A and B, considering nights from A as reference, all subjects from B were most similar with its own reference signature. Considering signatures from individual nights the accuracy paring subjects from A and B were 88% correct. Conclusion Nocturnal ear-EEG measures trait-like characteristics as reliable as scalp-EEG. The neural signature is stable over time within healthy subjects and demonstrated its ability as a personalized signature. Support (if any):

Описаны технологические подходы, применяемые для создания распределенных информационных систем поддержки научных исследований. Рассмотрены архитектурные решения, разработанные для создания таких систем и принципы интеграции этих систем с внешними источниками. Определены функциональные требования к модели такой информационной системы, которые обусловлены, во-первых, информационными потребностями исследователей, а во-вторых, необходимостью обеспечения надежного и долговременного хранения информации. Рассмотрены правила представления и преобразования метаданных. Описан и реализован прототип такой системы. The article addresses the description of technological approaches used to create distributed information systems for supporting scientific research. We describe the developed architectural solutions which are intended to create such systems and the principles for integrating of these systems with the external sources. The functional requirements for the model of such an information system are determined. These requirements are determined, firstly, by the information needs of researchers, and secondly, by ensuring a reliable and long-term storage of information. The considered model of SIS is implemented in the form of a prototype of the Electronic Library Management System (ELMS IRIS). ELMS IRIS operates with electronic collections. The electronic collection is considered as a set of information objects, united on a semantic basis and having the same structure (data schema). An ELMS allows to work with two types of collections which are the catalogs and the thesauri. The rules of representation and transformation of metadata are discussed. In order to organize metadata exchange between repositories and a metadata server (as well as with other systems with an extended profile), a special service is created that converts metadata from the internal schema into other metadata schemes. The OAI-PMH service is implemented, which periodically synchronizes the metadata of the repository and the metadata server in accordance with the schedule in batch mode. To fill the “Main metadata catalog”, in accordance with the metadata schemas created, managed dictionaries are used from the reference support block. To ensure data interoperability, the application server based on ZooPARK-ZS is also implemented, which provides access to system metadata via Z39.50 and SRW/SRU protocols. The developed model can be used as a model of the system for working with documents related to scientific and educational activities, since it solves the main tasks for these systems which are to provide a system for reliable long-term storage of digital (electronic) documents while preserving all the semantic and functional characteristics of source documents as well as ensuring “transparent” search and access of users to documents. These actions are necessary both for familiarization and for the analysis of the facts contained therein; and organization of collection of information on remote digital repositories supporting protocols OAI-PMH, SRW/SRU, Z39.50.
