OKUL ÖNCESİ ÖĞRETMENLERİNİN ERKEN OKURYAZARLIK BİLEŞENLERİ HAKKINDA FARKINDALIKL

This research aims to reveal preschool teachers' awareness of early literacy skills in the process of developing early literacy components and to determine what in-class activity practices are in this context. This research features a qualitative study design. The questionnaire form of the correspondence technique, which is one of the qualitative data collection techniques, was used in the data collection process. The Early Literacy Components Awareness and Practice Identification Questionnaire Form, which was created by the researchers as a correspondence technique form, consists of two parts, which include the personal information of the participants and questions for the purpose of the study. In the first part of the form, the demographic information of the participants such as professional seniority, educational status, early literacy course and special education and inclusion courses in undergraduate or in-service training were included. In the second part, there were questionnaire questions to determine the thoughts of the participants about the concept of early literacy and early literacy components (early literacy, phonological awareness, print awareness, verbal language development, letter knowledge) and their practices in the book centers in their classrooms. With the data obtained, content analysis was conducted in line with the participants' views on early literacy, phonological awareness, print awareness, verbal language development, letter knowledge and book center practices in their classrooms. This research, which was carried out with 32 preschool teachers, was carried out on a voluntary basis. The data obtained according to the answers given by the participants were subjected to content analysis. With the obtained data, codes and categories were reached. As a result of the research, it was determined that although preschool teachers do not seem sufficient in terms of knowledge, they provide these skills to children by performing early literacy activities on a practical basis. The study also determined that the teachers did not have a good command of the components of early literacy and that they increased the quantity of the book center instead of increasing its quality. Based on the results of the study, it is important that teachers who receive pre-school education are equipped with both practice and knowledge starting from their undergraduate education, and it is recommended that teachers who do not take the relevant course in undergraduate programs should be informed about early literacy through in-service training. In addition, it is recommended that book centers that support early literacy skills should be provided with the necessary physical equipment for qualified pre-school education in classrooms

Design and Emulation of Physics-Centric Cyberattacks on an Electrical Power Transformer

Malware that attack the electrical power grid consist of exploits and operations modules. The exploits are similar to those of traditional malware. These malware hack into an industrial computer and subsequently deploy operational modules. Some operational modules penetrate the operating system of the compromised industrial computer to take over computing functions and hence facilitate further attacks. Examples include interception of cryptographic keys, and generation of deceptive status data that indicate normal operation of a power transformer, while in reality the transformer is in distress due to the attacks. Other operational modules are designed to recognize and disrupt the physics of the physical equipment. We refer to these operations modules as physics-centric modules. The subject of this research is how physics-centric modules of malware can cause physical damage to power grid equipment. This research simulates a power transformer and a set of its protection algorithms. We make several contributions in this research, namely: i) we emulate in Python the protection algorithms that run on an industrial computer and monitor and protect a power transformer from a variety of faults; ii) we leverage these emulations to analyze the cyberattack surface of a power transformer; iii) with these insights at hand, we devise attack modus operandi that malware could use against a power transformer; and iv) we emulate these cyberattacks in Python to empirically observe and quantify their destructive effects on a power transformer. Our overall research findings in this paper serve the purpose of informing better defense against the physics-centric modules of malware that attack the electrical power grid.

Energy Management in Cloud Through Green Cloud Technologies

To address the issue of storage and processing of large-scale data, Cloud Computing has gained swift progression in the field of technology. Though offering solutions to many problems, cloud computing is still in the early stage of research and implementa-tion. It suffers from many challenges namely security, standardization and energy con-sumption. In this paper, we focus on the issue of energy consumption through cloud computing and the technology known as Green Cloud Computing to tackle the said issue. Green Cloud Computing plans to lessen the immense energy utilization, the re-quirement of physical equipment, destructive fossil fuel byproducts and so on. To shield our current circumstances from cloud technology’s adverse consequences, the cloud framework should be updated toward green registering. Green cloud computing broad-ly centers around the planning of effective clouds with green qualities like efficient en-ergy management, virtualization, load balancing, green servers, reusability, grid com-puting and recyclability.

Outlier‐robust set‐membership estimation for discrete‐time linear systems

AbstractIn many industrial applications, physical equipment for measuring may suffer from transient malfunctions, which can cause data outliers. This article addresses the problem of guaranteed set‐membership estimation of uncertain linear systems subject to outliers in measurements. To solve this problem, a robust set‐membership estimator is designed using the forward‐backward contraction procedure and a zonotopic filter. The setting up of these techniques offers two main advantages. On the one hand, outliers can be identified and discarded, which helps to resume the guaranteed property and avoid deadlock situations. On the other hand, the proposed method uses set‐inversion to fuse the available historical data, so as to attenuate the effect of uncertainties. Numerical examples are provided to show the efficiency of the proposed estimator.

Recent developments in engineering design for the quasi-axisymmetric stellarator CFQS

A quasi-axisymmetric stellarator, the CFQS, has been designed as a joint project of the National Institute for Fusion Science and Southwest Jiaotong University to prove intrinsic advantages of quasi-axisymmetry. Principal parameters of the CFQS are as follows: the major radius is 1 m, the magnetic field strength is 1 T, the aspect ratio is 4, and the toroidal periodic number is 2. The magnetic field configuration is designed based on that of the CHS-qa. Enhanced confinement properties within the context of neoclassical theory are achieved by its quasi-axisymmetric configuration. In the entire radial range, the magnetic well is retained to keep favourable stability features in the magnetohydrodynamic equilibrium. A magnetic field coil system was designed for the CFQS, which consists of 16 modular coils, 12 toroidal field coils, and 4 poloidal field coils. The supporting structure is designed to withstand strong electromagnetic force under 1 T operation, maintaining enough space for heating and diagnostic systems. The mock-up modular coil with the most complicated shape was constructed by Hefei Keye Electro Physical Equipment Manufacturing Co., Ltd. to check manufacturability and the achieved accuracy. A heat-run test was performed to check the temperature rise of conductors, and the capability of 1 T operation was confirmed. After various tests for the mock-up coil, construction of actual modular coils and the vacuum vessel has begun.

Managing the techno-economic impacts of partial string failure in multistring energy storage systems

The role of energy storage systems (ESSs) is becoming increasingly important for today’s electric power systems. Unavailability of an ESS assigned to critical grid services may cause unwanted disruption of those services and hence, may have a significant techno-economic impact. Like any physical equipment, an ESS is vulnerable to various types of faults. Failure of one or more strings in a multistring ESS does not have to be the cause of shutting down the entire ESS. It can still operate with a partial number of strings and continue providing critical services to the grid, if there are no reliability or safety issues and is acceptable under applicable standards. However, it is important to make sure that the control strategies are adaptable to the changes in ESS capacity caused by failed strings. Also, depending on the previous operation and type of failure, the reallocation of duty cycle burden among available strings could be non-uniform. These complexities suggest that mitigation of the impact of partial failure in multistring ESSs is not trivial and needs careful consideration. This is the topic of this paper. The proposed work investigates the impact of partial failure of a large multistring ESS on the assigned service and develops strategies to adjust the ESS control duty cycles for reducing such impacts. In doing so, the paper proposes a novel two-stage framework that plans for the multistring failure using robust optimization theory and then adjusts in real-time using a rule-based algorithm, based on the real-time information on the power availability of the string. Illustrations provided in this work are based on frequency regulation use-case, which is a common application for many utility-scale ESSs. A 750 kilowatt (kW)/1500 kilowatt-hour (kWh) 3-string ESS is used for the demonstration in this work and the efficacy of the proposed method is demonstrated and compared against methods that do not incorporate string failure in their strategy. In particular, we show that revenue loss of 93% can be incurred when partial string failure is not included in operation and planning. These losses in revenue are reduced by 60% with the proposed method.

The Study of Bending and Twisting Input Modalities in Deformable Interfaces

The deformable input provides users with the ability of physical operation equipment to interact with the system. In order to facilitate further development in flexible display interactive technology, we devised FlexSheet, an input device that can simulate the deformation environment. This paper presents two forms of deformation input, bending and twisting, with regard to three selection techniques. We conduct a controlled experiment to select discrete targets by combining two input forms and three selection strategies, taking into account the influence of visual feedback. Further, we use the deformation angle to reflect the degree of deformation and map it to the experimental variables. In accordance with the experimental results, we analyze the experimental performance under three evaluation indexes and prove the viability of our selection technology in bending and twisting input modes. Finally, we provide suggestions on the control level in bending and twisting input modes, respectively.

Current and Future Photography Techniques in Aesthetic Surgery.

BackgroundThe rapidly increasing modalities and mediums of clinical photography, use of 3-dimensional (3D) and 4-dimensional (4D) patient modeling, and widening implementation of cloud-based storage and artificial intelligence (AI) call for an overview of various methods currently in use as well as future considerations in the field.ObjectivesThrough a close look at the methods used in aesthetic surgery photography, clinicians will be able to select the modality best suited to their practice and goals.MethodsReview and discussion of current data pertaining to: 2-dimensional (2D) and 3D clinical photography, current photography software, augmented reality reconstruction, AI photography, and cloud-based storage.ResultsImportant considerations for current image capture include a device with a gridded viewing screen and high megapixel resolution, a tripod with leveling base, studio lighting with dual-sourced light, standardized matte finish background, and consistency in patient orientation. Currently, 3D and 4D photography devices offer advantages such as improved communication to the patient on outcome expectation and better quality of patient service and safety. AI may contribute to post-capture processing and 3D printing of postoperative outcomes. Current smartphones distort patient perceptions about their appearance and should be used cautiously in an aesthetic surgery setting. Cloud-based storage provides flexibility, cost, and ease of service while remaining vulnerable to data breaches.ConclusionsWhile there are advancements to be made in the physical equipment and preparation for the photograph, the future of clinical photography will be heavily influenced by innovations in software and 3D and 4D modeling of outcomes.

Contextual factors influencing a training intervention aimed at improved maternal and newborn healthcare in a health zone of the Democratic Republic of Congo

Maternal and neonatal mortality and morbidity in the Democratic Republic of Congo (DRC) are among the highest worldwide. As part of a quality improvement programme in a health zone in the DRC aimed at contributing to reduced maternal and neonatal mortality and morbidity, a three-pillar training intervention around childbirth was developed and implemented in collaboration between Swedish and Congolese researchers and healthcare professionals. The aim of this study is to explore contextual factors influencing this intervention. A qualitative research design was used, with data collected through focus group discussions (n = 7) with healthcare professionals involved in the intervention before and at the end (n = 9). Transcribed discussions were inductively analysed using content analysis. Three generic categories describe the contextual factors influencing the intervention: i) Incentives motivated participants' efforts to begin a training programme; ii) Involving the local health authorities was important; and (iii) Having physical space, electricity, and equipment in place was crucial. This study and similar ones highlight that incentives of various types are crucial contextual factors that influence training interventions, and have to be considered already in the planning of such interventions. One such factor is expectations of monetary incentives. To meet this in a small research project like ours would require a reduction of the scale and thus limit the implementation of new evidence-based knowledge into practice aimed at reducing maternal mortality and morbidity.

Are autonomous vehicles better off without signals at intersections? A comparative computational study

We model and analyze a futuristic intersection that serves only connected, autonomous and centrally managed vehicles. Under consideration are three control strategies that aim to minimize the total system delay by choosing an optimal trajectory for each vehicle. The first two abandon the concept of signal timing all together whereas the third strategy keeps it. The difference between the two signal-free strategies has to do with a fail-safe buffer requirement introduced to provide redundancy. Each control strategy leads to a unique version of a trajectory-based autonomous intersection management (T-AIM) problem, which is formulated as a mixed integer linear program and solved using both a commercial solver and a specialized heuristic algorithm. We find the signal-free strategy holds an overwhelming advantage over the signal-based strategy in terms of efficiency. However, its success is fragile and dependent on the faith in the safety and reliability of the system. When the fail-safe buffer is introduced, the efficiency of the signal-free strategy degrades to a level comparable to that of a properly optimized signal-based strategy. Surprisingly, the signal-free strategy with redundancy tends to arrange vehicles in groups that take turns to cross the intersection together. This “signal-like behavior” manifests itself whenever congestion rises to a certain threshold. In addition, solving the T-AIM problem based on signal timing enjoys significant computational benefits, because it eliminates many conflicts. Thus, the basic logic of signal timing – if not the physical equipment – may survive even after humans are no longer allowed to drive.

A Randomized Feasibility Trial of a Fundamental Motor Skill Parent-Mediated Intervention for Children with Autism Spectrum Disorders.

The purpose of this pilot study was to examine the feasibility of a fundamental motor skills (FMS) intervention with two groups on the acquisition of FMS of children with autism spectrum disorders (ASD). We randomly assigned families (n = 15) of children with ASD aged 4–11 years into two groups (a workshop or a home-based group) focused on FMS development. Both groups participated in a 10-week intervention and were given the same instructional manual and adapted physical activity equipment. The workshop group also attended four in-person workshops targeting the needs of children with ASD and their parents. Children were tested on their FMS using the third edition of the Test of Gross Motor Development at the start and end of the intervention and then three months following the intervention. The recruitment rate was 50%, and the retention rate was 80% for all participants. The intervention for groups was safe and accepted by the participants as evaluated by post-program interviews. The outcomes of this pilot study suggest that parents can facilitate the acquisition of FMS of their children with ASD. Although these results are positive, there is a need to further identify effective interventions for FMS development in children with ASD.
