Research on Time Optimization Algorithm of Aircraft Support Activity with Limited Resources

Reading and writing difficulties (RWD) in learners pose significant challenges not just for children but also for parents. While there is limited support available for children with RWD and their parents in Mauritian schools, research may reveal areas of parental need that speech-language therapists may address. The aim was to determine parents’ perspectives regarding their Grade 4 children with RWD in mainstream government schools in Mauritius. Teachers identified children with RWD with the Screening Tool for Learning Disorder, and parents were requested to participate in the study. Sixty-seven parents completed a questionnaire investigating their perspectives on the symptoms and causes of their child’s RWD and the ways in which they assist their child. The screening tool differentiated between children at risk of specific learning disorder (SLD) and children who indicated clear symptoms of SLD. The results of the tool did not correspond closely with the participants’ satisfaction with their child’s academic performance. The majority of participants could, however, identify RWD in their children when descriptions were given. Parents mostly cited laziness as the main cause of their child’s RWD. The results showed that participants had limited information about the causes and symptoms of RWD and SLD. There is a lack of awareness about the role of speech-language therapists in the intervention of RWD. There are limited resources and support for children with RWD, despite an inclusive education policy in Mauritius. Speech-language therapists and teachers should collaborate to support children with RWD and their parents using inclusive education strategies.

The considerable increase in the complexity associated with the formulation of maintenance plans has enabled the development of new techniques to bring maintenance scheduling optimization models to more realistic environments. In this sense, a previous optimization model was proposed considering the use of time windows for the formation of grouping schemes under an opportunistic strategy for maintenance activities considering non-negligible execution times, thus offering the possibility of analysing scenarios with limited resources. This article proposes a risk analysis based on the failure probability of each component involved in the maintenance scheduling optimization model, which has the particularity of enabling a greater number of combinations of grouped PM activities. Moreover, it seeks to identify the general behaviour of the optimization model against different scenarios of periodicities and execution times of each maintenance activity. The proposed optimization model is formulated under a mixed integer linear programming (MILP) paradigm and its objective function seeks to minimize the unavailability of the system associated with the execution times of the activities developed, generating different experimental cases, and varying the start time scheduling under a tolerance factor from 0% up to a maximum of 25% for advance or delay. Results show in contrast with the base optimization model, an 8% less unavailability when the tolerance factor is 10%. Finally, it was possible to quantify the risk present in each maintenance schedule, at the same time a behaviour towards advancing PM activities is evidenced by the optimization model proposed over the delay.

Glucometrics (defined as the systemic analysis of blood glucose data) can be used as a benchmarking tool/ quality indicator of glycemic control in hospital or a patient care unit of the hospital.1,2 Metrics generated are utilized to compare the quality of care provided to patients along with other indicators like rates of pressure sores and catheter related blood stream infections.2 The study of glucometrics entails use of automated glucometers3 and automated data management systems.4 In hospitals with limited internal information technology (IT) resources and capability, accessing and assessing the large amount of glucose data generated, remains a challenge. In our hospital with resource limited IT capability, we wanted to evaluate if chart abstraction technique,5 can be used to effectively generate glucometrics. We also studied use of the generated metrics to evaluate in-patient glycemic control in ICU patients and its use as a benchmarking tool, to compare it with other hospitals and centers of excellence. Indoor records of all patients admitted to ICU of our hospital from July 2011 to September 2011 were evaluated. Data regarding blood glucose level (BSL), its timing, its relation to feeding, as well as insulin dose and type given at that time, along with patient characteristics were noted. All this data was entered into a spreadsheet and then analyzed to generate metrics. A Glucometrics Report (Table 1) was prepared for the period of assessment. The glucometrics data was compared with data from other hospitals.4 Table 1. Glucometrics Report of Our Study. The data required to generate glucometrics for a hospital or unit of the hospital can be collected by the following methods: Analysis of the actual medical records (chart abstraction technique):5 Pros: BSL values can be correlated with meal timings and with treatment given. Cons: labor-intensive. Analysis of data from automated lab information systems:3-5 Pros: more efficient, large amount of data analyzed in a much shorter time, data from all patients can be analyzed. Cons: need for automated glucometers and laboratory information systems; cannot correlate BSL with meals and action taken. Hospitals with limited IT resources can connect to and import their data to external data management systems.4 For hospitals with limited IT resources and who are unable to connect to these external data management systems due to their geography or other limitations, the chart abstraction technique remains the only option. As the process is labor-intensive, only a convenience sample of records can be analyzed. But, this technique offers a chance for institutes to assess their in-patient glycemic control. The glucometrics report offers a glimpse into the world of glycemic control at that hospital during the period of the study and to compare it with results from other hospitals and centers of excellence.4 The limitations of our study are that it was a single unit study, with a small sample size. Thus, in hospitals with limited IT support, chart abstraction technique can be used to generate these metrics. Even in the United States, more than half (59%) of the hospitals do not have an automated capability to extract and analyze glucose data.6 Our study can be useful for all these hospitals.

Colon Cancer Screening Models: Lessons and Challenges

PurposeThis study examined the relationship between Physical Activity and Sitting Time Balance Index (PASTBI) and mortality outcomes, including all-cause, cardiovascular diseases (CVD)-, and cancer-specific mortality, in a nationally representative cohort of US cancer survivors.MethodsData were derived from the National Health and Nutrition Examination Survey 2007–2018. The PASTBI was calculated using information from the Global Physical Activity Questionnaire, with mortality data obtained through linked databases. Cox proportional hazards models with survey sample weights were applied to estimate hazard ratios (HRs) for all-cause, CVD-related, and cancer-related mortality, adjusting for potential confounders.ResultsThe analysis included 3334 cancer survivors, with an average follow-up of 72.02 months. Compared with quartile 1, participants in quartile 4 (highest PASTBI) had significantly lower mortality risks, including 62% lower all-cause mortality [HR = 0.38; 95% CI = 0.29–0.50], 55% lower CVD mortality [HR = 0.45; 95% CI = 0.23–0.86], and 56% lower cancer mortality [HR = 0.44; 95% CI = 0.27–0.71]. Additionally, while both quartile 1 and quartile 2 reported no physical activity time, individuals in quartile 2, who had shorter sedentary time, exhibited lower mortality risks [all-cause mortality HR = 0.62; 95% CI = 0.49, 0.79; CVD mortality HR = 0.54; 95% CI = 0.35, 0.84; cancer mortality HR = 0.75; 95% CI = 0.54, 1.06].ConclusionA higher PASTBI score, reflecting a better balance of physical activity and sedentary time, was associated with lower risks of all-cause, CVD-, and cancer-related mortality. Reducing sedentary time, even modestly, offers significant health benefits, independent of physical activity levels.

continues. The experiences from the Decade of Action will help us to define an effective roadmap for the next decade. Vehicle safety has been one the areas that has been subjected to significant changes over the past decade with advancements in technology, especially in the field of active safety. This change in the field has been more tangible in High Income Countries (HICs). This note suggests a path to determine the effect of vehicle safety in Iran as a Low/Middle Income Country (LMIC), considering the road safety management structure of the country and introduces the priorities that need to be the subject of focus in further stages. As the “Safe System Approach for Road Safety” focuses on reducing the fatalities and injuries, the interactions between human body and the surrounding area, the vehicle becomes an important issue. Therefore, vehicle designs that meet modern safety standards, with the goal of reducing the risk of occurrence of crashes and ensuing injuries become more prominent. As these advancements in active and passive safety features are being introduced in HICs, the nature of these technologies and limited resources in LMICs, require a deeper understanding of the effectiveness of these technologies would help us set more effective strategies in such countries. A profound understanding of the causes of crashes and the following injuries, is an essential step in setting precise strategies to continue reducing fatalities. This issue has been one of the targets during the decade of action, but a structured regime with independence from involved key stakeholders, must be established to precisely determine the role and details of the involvement of vehicle design and technical aspects in occurrence of the crashes and following injuries. As utilizing advanced technologies for upcoming future is a must to enhance the vehicle safety, considering the economic status of the country besides the evidences in the trend of crashes in Iran suggest effective interventions to achieve results in the shortest time, it would be important to examine the possibility of introducing some of the technologies in the shortest possible time, for example: New Car Assessment Program (NCAP) ratings for new car models. ABS/Combined Braking systems and daytime running lights for powered two-wheelers. Automatic Emergency Braking Systems for cars. Electronic stability control systems (ESC) Such interventions can also be considered as a platform that practices the utilization of new processes in LMICs that can improve in the next stages

Animal aggregations can occur for a variety of abiotic factors, such as resource limitation, or biotic factors, including group foraging and protection from predators. In our study, we examined whether time, sex, body size or shelter availability affected aggregation behavior of the maritime earwig, Anisolabis maritima (Order Dermaptera), an insect found globally at high densities under driftwood. Specifically, we monitored the distribution of two individuals in arenas with either two shelters (no habitat limitation) or one shelter (habitat limitation) to determine their propensity for cohabitation at times of peak activity and times of quiescence. Females, whose high levels of aggression are often associated with maternal care, were particularly averse to cohabitation, whereas males were generally more tolerant of other earwigs. Females initially preferred not to cohabitate when placed with a male, but were more tolerant of cohabitation later, regardless of the number of shelters. Same-sex pairs, on the other hand, were less likely to cohabitate with only one shelter present, but males were again more tolerant of conspecifics than females regardless of habitat limitation. When competition for one shelter did not lead to cohabitation, the lone occupant was more likely to be the larger individual in same-sex trials and females in mixed-sex trials. Understanding the tolerance for close proximity under these varying conditions may provide insight into aggregative behavior and spatial distribution patterns in the maritime earwig.

This research aims to analyze the factors inhibiting the implementation of e-government in public service particularly in the application of SIAKAD Program in STAIN Ponorogo. First, it describes how e-government becomea national policy since the issuance of Presidential Instruction Number 3 of 2003 was applied in STAIN Ponorogo, particularly in SIAKAD program. The factors that affected the implementation of e-government are explained using theory of policy implementation adapted from Edwards and Van Horn Van Meter’s model. This case study concludes that the implementation of e-government in public service were constrainedby poor communication between executors, limited resource available and limited support from the bureaucratic structure of the SIAKAD Program.

This study investigates the implementation of Project-Based Learning (PBL) as a means to improve critical thinking skills in early childhood. The research was conducted at Nurul Hikmah Integrated Islamic Kindergarten (TKIT) and Handayani III Kindergarten (TK) in Penajam Paser Utara District, with the aim of supporting the implementation of the independent curriculum. This study uses a qualitative research design, using data collection techniques such as interviews, observations, and document studies. while data collection techniques are carried out by condensing data, displaying data, and drawing conclusions. The research findings show that PBL has proven to be an effective approach in improving early childhood critical thinking skills. Through the implementation of carefully planned PBL activities, children showed significant progress in their ability to identify problems, generate creative solutions, and consider different perspectives. In addition, PBL encourages the development of social skills, collaboration and creativity through teamwork and group discussions. Based on the research findings, it is recommended that the implementation of PBL in early childhood education follows a structured process. This includes defining clear learning objectives, selecting interesting and relevant project topics, setting realistic time frames, defining assessment criteria, providing necessary materials and resources, and offering guidance and support throughout the learning process. This research contributes to the existing literature by providing insights into the effective implementation of PBL to enhance critical thinking skills in early childhood education. The findings underscore the importance of well-structured planning, implementation, and evaluation to maximize the benefits of PBL. Further research is encouraged to explore additional factors and strategies that can further improve PBL implementation and outcomes in early childhood education settings. This study also identified several supporting factors that influence the successful implementation of PBL, including: the presence of creative and visionary teachers, a conducive learning environment, relevant learning content and the availability of resources. Conversely, inhibiting factors such as limited support from families, rigid curriculum constraints, limited resources and time constraints were also recognized.

Time has always been considered as a limited resource. People distribute the limited 24 hours in a day to various activities to fulfill their needs. Leisure activities, also known as discretionary activities, include social activities such as meeting friends and family and recreational activities such as going to the cinema. People distribute the 24 hours in each day to each of these activity types based on their wants and needs. Every person uses different resources to produce goods, which provide them their earnings. In the simplest terms, multitasking could be defined as doing multiple things simultaneously. The term was first used to describe the simultaneous execution of computer activities, after which it was co-opted and is now being commonly used concerning people’s activity participation and time allocation behavior. Travel is one of the few activities which provide the scope of unrestricted participation in multitasking activities.

Human resource development professionals serve many diverse populations of learners in the workplace. They do so with limited resources which leads to a dilemma: How to most effectively and efficiently meet the needs of all learners in the workplace, given the different job duties, backgrounds, skills and abilities of each learner. This empirical study examines job training satisfaction among customer and technical service employees in nine different organizations in the US and Canada. The study concluded that there were no differences in job training satisfaction when examined with dimensions of diversity such as age groups, gender and race/ethnicity. There were differences in job training satisfaction, however, when examined with job type, job status, and job tenure.

When some household appliances are running, the electrical quantities such as active power and reactive power will change slowly for a long time, which will affect the feature extraction of event-based non-intrusive load identification, resulting in low accuracy of load identification results. In view of this situation, a feature extraction method is proposed. Its core idea is that there is a certain law in the change of active power and reactive power in a very short time, and the curve can be fitted to speculate the values of these electrical quantities in the next time, so as to eliminate the influence. Based on this, a feature extraction method applied to non-intrusive load identification is realized. The test results show that this method can effectively improve the accuracy of non-intrusive load identification feature extraction data, and has good application value.

Abstract. Early diagnosis and treatment are vital to improving lung cancer patients’ quality of life and survival rate. This study aimed to investigate the value of dynamic enhanced scanning examination by computed tomography (CT) in early lung cancer diagnosis. One hundred and twenty patients with isolated lung nodules were selected to analyze this diagnostic method, using pathological diagnostic results of cancer as the gold standard. Of the 120 pa-tients with isolated pulmonary nodules, the diagnosis was confirmed by patho-logical examination in 96 patients with early lung cancer (adenocarcinoma of the lung) and 24 patients with benign lung lesions. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT dynamic enhancement scans for the diagnosis of early-stage lung cancer were 93.75%, 83.33%, 91.67%, 95.74%, and 76.92%, respectively. Early-stage lung cancer had significantly less blood volume and a noticeably shorter mean time to passage than benign lung lesions (p<0.01). Blood flow and surface permeability were higher in early-stage lung cancer than in benign lung lesions (p<0.05). The ar-eas under the receiver operating characteristic (ROC) curves for blood volume, blood flow, surface permeability, and mean time to passage for the diagnosis of early-stage lung cancer were 0.737, 0.724, 0.779, and 0.946, respectively. In conclusion, CT dynamic enhancement scan has good application value in diag-nosing early lung cancer and is worth promoting in clinical practice.
