The Effect of Childcare Teachers’ Emotional Intelligence on Turnover Intention: The Mediating Effect of Job Stress and Job Satisfaction
Authors:   Academic Society of Global Business Administration, Park Sun-Hee , Shin Ho-Chul
Published: March 2023

In order to help the healthy development of infants and young children, the role of childcare teachers who affect infants and young children is important. However, the high turnover rate of childcare teachers can lead to a deterioration in the quality of childcare services. In this study, in order to lower the turnover rate of childcare teachers, emotional intelligence was noted as the cause of turnover intention. In addition, the mediating role of job stress and job satisfaction was verified to identify the process through which the relationship between emotional intelligence and turnover intention is connected. In this study, 224 childcare teachers working in daycare centers were surveyed, and 203 of them were used for analysis. As a result of the analysis, it was confirmed that the emotional intelligence of childcare teachers had a significant effect on turnover intention. In addition, it was found that job stress and job satisfaction had a significant partial mediating effect between emotional intelligence and turnover intention. The theoretical implications of this study confirmed the theoretical model predicting the effect of emotional intelligence on turnover intention. Also, the sequential process of emotional intelligence affecting turnover intention through job stress and job satisfaction was identified. These results are meaningful in that they provide practical implications for preparing a plan to reduce the turnover intention of childcare teachers. Based on these research results, the limitations of this study and future research directions were presented.
Impact of audit efforts of the avoid losses firms on accounting transparency: Focused on audit time and audit fees
Authors:   Academic Society of Global Business Administration, Han Jiyeon , Jung Kyoung Chol
Published: March 2023

This study confirms whether the effect of lowering accounting transparency was mitigated when the audit effort of the avoid losses firms was high. Firms in the avoid losses section may have lower accounting transparency, but the purpose is to confirm that the moderating effect on the auditor's characteristics(audit time, audit fee) can alleviate the effect of lowering accounting transparency. As a result of the analysis, we confirm that accounting transparency was alleviated as the audit effort (audit fee, audit time) of the avoid losses firms increased. This can be interpreted as an increase in audit efforts of the avoid losses firms alleviated the decrease in accounting transparency by complying with accounting and audit standards by fully exercising their monitoring and supervisory functions. In addition, it can be seen that the same result was found when the deficit avoidance section was analyzed as a company from a narrow section to a wide section as part of robustness. This results imply that accounting transparency varies depending on the audit efforts of the avoid losses firms. Through this, it is contributing to the verification that the impact of the avoid losses firms on accounting transparency acts differently depending on audit time and audit fees. These results suggest changes in the audit environment in Korea to improve the accounting transparency of firms in the crisis of deficit.

AbstrackEarly Childhood Education is the level of education given before children enter the basic education level. This level carries out learning activities for early childhood. In this age range, children are in the golden age, which is a period where the child's brain can develop very rapidly both in physical growth and mental development. Therefore, early childhood needs to be given educational stimuli that are appropriate to their age level so that all children's potentials grow and develop optimally. There are six aspects of development that must be stimulated in order to achieve the standard of development achievement. This article attempts to describe developmental achievements for children aged 5-6 years using the study literacy method from several similar journals that have existed previously as a reference. Based on the research conducted, the stages of achievement of the growth and development of children aged 5-6 years in every aspect can be maximized by providing educational stimulation that pays attention to the principles of early childhood learning, through fun learning and playing experiences.  Keyword: Proposal, STPPA, 5-6 years.

RESIDENTIAL SPATIAL DIFFERENTIATION AT THE COMMUNITY LEVEL IN HANGZHOU, CHINA
Authors: Zhang Ling , Wu Baihong
Published: March 2023

Residential spatial differentiation is an important social issue for every large city to explore. The “subcultural” clusters formed by the subjective choices of a city’s residents divide the living spaces of the city and create residential differentiation. A study of this phenomenon would help to facilitate the allocation of urban resources and the formulation of relevant development strategies. In recent years, Hangzhou, one of the major developed cities in China, has seen a gradual increase in the proportion of its non-local population. Employing principal component analysis and K-means clustering, this study investigated the city’s spatial differentiation of living spaces at the community level and identified the social clustering areas. The Shannon-Wiener index and the index of dissimilarity were used to examine the degree of residential segregation in each administrative district. The results showed that the functional distinctions among the districts of Hangzhou were pronounced and had certain degrees of class solidification. A certain spatial coupling was observed between residential differentiation and housing prices. More reasonable allocations of social resources would help to ameliorate the negative effects caused by the spatial differentiation of living spaces.
Prospects for Extending the Core-collapse Supernova Detection Horizon Using High-energy Neutrinos
Authors: Valtonen-Mattila Nora , O’Sullivan Erin
Published: March 2023

Large neutrino detectors like IceCube monitor for core-collapse supernovae using low-energy (MeV) neutrinos with a detection reach from a supernova neutrino burst to the Magellanic Cloud. However, some models predict the emission of high-energy neutrinos of GeV–TeV from core-collapse supernovae through the interaction of ejecta with circumstellar material with energies of TeV–PeV produced through choked jets. In this paper, we explore the detection horizon of IceCube for core-collapse supernovae using high-energy neutrinos from these models. We examine the potential of two high-energy neutrino data samples from IceCube, one that performs best in the northern sky and one that has better sensitivity in the southern sky. We demonstrate that, by using high-energy neutrinos from core-collapse supernovae, the detection reach can be extended to the megaparsec range, far beyond what is accessible through low-energy neutrinos. Looking ahead to IceCube-Gen2, this reach will be extended considerably.
New Determinations of the Surface Abundances of HD 1280
Authors: Monier Richard
Published: March 2023

New abundances for several chemical elements are measured for HD 1280 using updated atomic data and spectrum synthesis. The abundances of calcium and scandium are solar whereas strontium is mildly overabundant. The abundances of helium, magnesium, titanium, chromium, manganese, iron and barium are in good agreement with a former abundance analysis. This reinforces the status of HD 1280 as a normal rapidly rotating A star with essentially normal abundances of elements lighter than iron and mild overabundances of heavier elements which may actually have been present in the environment where the star was born.

We identify evidence of activity in observations of 238P in 2021, and find similar inferred activity onset times and net initial mass-loss rates for 238P during perihelion approaches in 2010, 2016, and 2021. P/2016 J1-A and P/2016 J1-B are also found to be active in 2021 and 2022, making them collectively the tenth MBC confirmed to be recurrently active near perihelion and therefore likely to be exhibiting sublimation-driven activity.

Inhibition of absence seizures in a reduced corticothalamic circuit via closed-loop control
Authors: Xie Yan , Zhu Rui , Tan Xiaolong , Chai Yuan
Published: March 2023

Inhibition of spike-wave discharges (SWD) was thought to be associated with remission of seizure symptoms in absence epilepsy. In the previous studies, pulse stimulation was applied directly to the brain as an effective means to inhibit SWD. However, this method not only failed to provide a real-time tracking control of the disease, but also caused incalculable damage to the patient's brain tissue. To fill the gap, this work studied the mitigation and elimination effects of SWD by applying single-pulse coordinated resetting stimulation (SCRS) to three different neurons, firstly. Secondly, based on the 2I:2O cortical-thalamic model (2I:2O SCT model), four kinds of m:n on-off SCRS with the same period were compared, and the control efficiency and impulse energy consumption were combined to investigate these different stimulations. Finally, we further optimized the regulation strategies, including the weighted structure of stimulation and closed-loop control. Simulation results show that the weighted stimulation and closed-loop control strategy proposed here further improve control performance by reducing energy consumption, which may be more reliable in applications. Moreover, this study provides a new method for optimizing SCRS by the weighted processing and closed-loop control of electrical pulses to alleviate the absence epileptic state.

By constructing a Savitzky-Golay-TCN deep convolutional neural network, the systemic risk indicators of China's financial market are predicted, and their accuracy and reliability are analyzed. The research found that: 1) Savitzky-Golay-TCN deep convolutional neural network has a strong generalization ability, and the prediction effect on all indices is stable. 2) Compared with the three control models (time-series convolutional network (TCN), convolutional neural network (CNN), and long short-term memory (LSTM)), the Savitzky-Golay-TCN deep convolutional neural network has excellent prediction accuracy, and its average prediction accuracy for all indices has increased. 3) Savitzky-Golay-TCN deep convolutional neural network can better monitor financial market changes and effectively predict systemic risk.
Integrated-Flexible Research Methodology
Authors: Saliya Candauda Arachchige
Published: March 2023

The research process is not a smooth process that moves from one stage to another, or a sequential process growing from the roots of ontology and epistemology towards the data collection and analytical techniques and interpretations. The existentialist position of the interpretive / reformist paradigm is that reality is subjective and multiple, that it does not exist independently in the human mind. Their epistemological stance is that the available knowledge depends on the researcher's thoughts and desires. That is, “knowledge” is created by the seeker and deploying a specific methodology which is not necessarily a sequential set of “stages”, a “step-by-step” course or a “layer-by-layer” peeling activity like peeling-off an onion.
Social Science Philosophy Behind Data Analysis With Special Reference to Philosophical Perception
Authors: Peprah Kenneth
Published: March 2023

Philosophy is a science of knowledge, and it concentrates on epistemology, ontology, axiology, and methodology. However, researchers have understated the role of philosophy, even though it is very interwoven with research. This chapter is to position data analysis in philosophy and show its epistemological and ontological underpinnings using the philosophy of perception. The methods are a desk study, literature reviews, and lecture notes. Traditionally, the definition of knowledge is ‘justified true belief' (JTB). The JTB is placed in the context of empiricism, rationalism, and/or dualism. These are further linked to ontological materialism, idealism, and dualism. The chapter has tried to draw a relationship with perception's direct realism, indirect realism, and dualism respectively. In conclusion, knowledge is justified by good evidence (empiricism) and reason (rationalism). The chapter recommends researchers utilise the philosophy of the sciences in order to improve on their research.
Analytical Network Process in Decision Making
Authors: Jayawardena Thantirige Sanath Siroshana , Jayawardena Chandimal Sanjeewa
Published: March 2023

Analytic Network Process (ANP) is a generalized form of the Analytical Hierarchical Process (AHP). AHP is an objective theory of deriving the decision makings on absolute scale values starting from subjective relative measurements perhaps on tangible or intangible or a mix of both rated by the experts. A consistency measure of the relative ratings is verified with a consistency ratio to assure the ratings of the experts are consistent. The clustering of criteria/sub-criteria with inner and outer dependencies as well as feedback is taken into account in ANP. In ANP rather than a hierarchical process, a network structure is assumed and all nodes in the network are treated equally with interaction between nodes and grouping into clusters. A super-matrix is constructed, then normalized it to get weighted super matrix and raised it to a sufficient power to converge this into a unique eigen vector representing the final weights in limit super-matrix. Step by step iterations of ANP was demonstrated with a selection of car example.

Businesses must prioritize customer complaints because they highlight critical areas where their products or services may be improved. The goal of this study is to use machine learning approaches to anticipate and evaluate customer complaint data. The current study used logistic regression and support vector machine (SVM) to predict customer complaints, and evaluated the datasets using machine learning techniques after collecting five distinct length datasets from the Consumer Financial Protection Bureau (CFPB) website and cleaning the data. Both logistic regression and SVM can accurately predict customer complaints, according to this study, but SVM gives the greatest accuracy. The current study also found that SVM provides the highest accuracy for a one-month dataset and Logistic regression provides for a three-month dataset. In addition, machine learning codes were utilized to display and tabulate consumer complaints across many dimensions.

Every participant in the system has the opportunity to become a member of the holding committee and have sufficient anonymity. During the life cycle of serving as the holding committee members, they only send one message in the protocol without excessive interaction, and achieve receiver strong anonymity with a capability-based encryption scheme different from most public-key encryption schemes, at present named RiddleEncryption, which is also proposed in this paper. In RiddleEncryption the sender does not need to pay attention to the specific identity of the receiver but focuses on what kind of capability the receiver should have. Nobody can determine this kind of capability at the beginning of the system establishment. This article aims at depositing a secret in a distributed manner (e.g., blockchain) without excessive trust and to emphasize more anonymity and capability. The scheme can be used in the dynamic groups, authentication management, rights abuse prevention, and so on.
Epsilon-Greedy-Based MQTT QoS Mode Selection and Power Control Algorithm for Power Distribution IoT
Authors: You Xinhong , Zhang Pengping , Liu Minglin , Lin Lingqi , Li Shuai
Published: March 2023

Employing message queuing telemetry transport (MQTT) in the power distribution internet of things (PD-IoT) can meet the demands of reliable data transmission while significantly reducing energy consumption through the dynamic and flexible selection of three different quality of service (QoS) modes and power control. However, there are still some challenges, including incomplete information, coupling of optimization variables, and dynamic tradeoff between packet-loss ratio and energy consumption. In this paper, the authors propose a joint optimization algorithm named EMMA for MQTT QoS mode selection and power control based on the epsilon-greedy algorithm. Firstly, the joint optimization problem of MQTT QoS mode selection and power control is modeled as a multi-armed bandit (MAB) problem. Secondly, the authors leverage the online learning capability of the epsilon-greedy algorithm to achieve joint optimization of MQTT QoS mode selection and power control. Finally, they verify the superior performance of the proposed algorithm through simulations.
Classification of Tweets Into Facts and Opinions Using Recurrent Neural Networks
Authors: Pattusamy Murugan , Kanth Lakshmi
Published: March 2023

In the last few years, the growth rate of the number of people who are active on Twitter has been consistently spiking. In India, even the government agencies have started using Twitter accounts as they feel that they can get connected to a greater number of people in a short span of time. Apart from the social media platforms, there are an enormous number of blogging applications that have popped up providing another platform for the people to share their views. With all this, the authenticity of the content that is being generated is going for a toss. On that note, the authors have the task in hand of differentiating the genuineness of the content. In this process, they have worked upon various techniques that would maximize the authenticity of the content and propose a long short-term memory (LSTM) model that will make a distinction between the tweets posted on the Twitter platform. The model in combination with the manually engineered features and the bag of words model is able to classify the tweets efficiently.
Lipoteichoic Acid Inhibits Lipopolysaccharide-Induced TLR4 Signaling by Forming an Inactive TLR4/MD-2 Complex Dimer
Authors: Watanabe Sachiko , Zenke Kosuke , Muroi Masashi
Published: March 2023

LPS interacts with TLR4, which play important roles in host-against-pathogen immune responses, by binding to MD-2 and inducing an inflammatory response. In this study, to our knowledge, we found a novel function of lipoteichoic acid (LTA), a TLR2 ligand, that involves suppression of TLR4-mediated signaling independently of TLR2 under serum-free conditions. LTA inhibited NF-κB activation induced by LPS or a synthetic lipid A in a noncompetitive manner in human embryonic kidney 293 cells expressing CD14, TLR4, and MD-2. This inhibition was abrogated by addition of serum or albumin. LTAs from different bacterial sources also inhibited NF-κB activation, although LTA from Enterococcus hirae had essentially no TLR2-mediated NF-κB activation. The TLR2 ligands tripalmitoyl-Cys-Ser-Lys-Lys-Lys-Lys (Pam3CSK4) and macrophage-activating lipopeptide-2 (MALP-2) did not affect the TLR4-mediated NF-κB activation. In bone marrow–derived macrophages from TLR2−/− mice, LTA inhibited LPS-induced IκB-α phosphorylation and production of TNF, CXCL1/KC, RANTES, and IFN-β without affecting cell surface expression of TLR4. LTA did not suppress IL-1β–induced NF-κB activation mediated through signaling pathways shared with TLRs. LTAs including E. hirae LTA, but not LPS, induced association of TLR4/MD-2 complexes, which was suppressed by serum. LTA also increased association of MD-2, but not TLR4 molecules. These results demonstrate that, under serum-free conditions, LTA induces association of MD-2 molecules to promote formation of an inactive TLR4/MD-2 complex dimer that in turn prevents TLR4-mediated signaling. The presence of LTA that poorly induces TLR2-mediated activation but inhibits TLR4 signaling provides insight into the role of Gram-positive bacteria in suppressing inflammation induced by Gram-negative bacteria in organs such as the intestines where serum is absent.
Example Application of a Standard Approach to Identifying and
Defining Functions for Systems Development and Safety
Assessments
Authors: Darrah Paul D.
Published: March 2023

The Safety Assessment Process defined by SAE ARP4761 [1] and associated regulatory guidance and the system
development process defined by SAE ARP4754 [2] are built on an understanding of the functions performed by a
system or systems. SAE Technical Paper 2022-01-0008 [3] proposes a process to assist the system or product
developer with identifying and describing functions at each level of abstraction
used in describing the architecture.

This paper walks through the process described in SAE Technical Paper
2022-01-0008, examining some of the issues and considerations encountered using
this approach, and resulting in an example function list for a passenger
aircraft. The example aircraft is typical except that an autonomous operating
mode is included.

Laser Cladding Technology

Published: March 2023

This paper will illustrate the surface treatment coating that forms a strong
metallurgical bond between the titanium alloy matrix regarding the high friction
properties and challenging lubricating of titanium alloys. In this research, TC4
has been selected as a base material instead of TiC. Then Ni-composite coating
was employed as the surface treatment of TC4 by laser cladding (LC) process. The
Ni-based alloy coating material powder is good self-fluxing, has
high-temperature resistance, and is analytically pure with 200 mesh. The
chemical properties of Ni composite coating include 31.2 % Chromium, 8%Titenium,
and 3.6% Carbon. Overall characterization and microstructure analysis of the
prepared coating utilizing OM, XRD, SEM, EDS, and EPMA with different
laser-specific energies (LSP) performance impact. It is evident that an
excellent coating can be employed at the LSP of about 12.5kJ/cm2. The
TiC ceramic particle reinforced phase is dispersed into a two-phase solid
solution of β-Ti and γ-Ni. The micro-hardness of the employed coating is greater
than the base alloy. This research also optimized that laser power is
proportional to the coating structure. This research has practical value in the
modern aerospace and automobile industry to increase the application of titanium
alloy.
Newtons vs Teslas: The Dependence of Reactionless Drive Thrust on a
Stationary Magnetic Field: Part 1
Authors: Chen Ed , Cronin Tara
Published: March 2023

The reactionless drive is an internal momentum engine which until recently has
been deemed impossible under the laws of physics. In this paper, the authors
will extend the equation for reaction less propulsion =
F=−μq2/6πcmr2v×dBdt+B×dvdt

and derive an additional equation, which we call “The Sektet Equation” governing
the system of motion,
FSek=−μq2/6πcmr2∗2B∗dBdt.

The results of the paper show that significant thrusts can be generated on
relatively low voltages and energy inputs. It applies this equation to explain
how NASA’s EM drive likely produces thrust via the “Sektet Equation” using a
three circuit analysis of the Sektet Force.
Experimental and Computational Study of Auto-ignition in the New
Prototype Engine with Focusing Compression due to Supermulti-Jets
Colliding

Published: March 2023

We have proposed a new compressive combustion principle leading to the
auto-ignition of fuel by focusing compression due to the collision of the pulsed
supermulti-jets. This principle has the potential of nearly-complete air
insulation due to encasing burned gas around the center of the combustion
chamber and a high compression ratio around the chamber center while suppressing
vibration and noise levels. We have developed the first prototype engine having
a very small combustion chamber of a diameter of 18 mm and also 14 side passages
for the supermulti-jets colliding at the chamber center. Combustion experimental
results indicating air insulation effect and high thrust over 100 N were
obtained as basic data for various types of applications, including automobiles
and aerospace usage such as for rockets. However, it was found that higher
compression due to more jets is necessary to get stabler combustion. Therefore,
by using a metal 3D printer, we have developed the second engine with 24 side
passages of gas jets colliding, while performing direct injection of liquid fuel
at injection pressure over 5 MPa into the combustion chamber. In our previous
report, the experiment without combustion and its computational simulation show
that the second engine enables a higher compression ratio than that of the first
prototype engine. In this research, we conduct fundamental combustion
experiments using the second engine with a direct injection system, purposing to
achieve stable multi-cycle combustion with auto-ignition of the fuel by focusing
compression due to the collision of supermulti-jets. As a result, a stabler
occurrence of combustion is confirmed for the second engine. Experimental data
of wall pressure obtained also indicate that auto-ignition occurs due to
collision of the supermulti-jets while showing a possibility of higher thrust
over 300 N. Furthermore, we qualitatively perform computations of reacting flows
for the second engine, while showing liquid fuel spray atomized strongly by the
gas jets.
Designing and Innovating for Circularity: An Engineering Life Cycle
Approach for Complex and Certified Products
Authors: Meldrum Rebecca
Published: March 2023

The concept of the circular economy provides a framework for a more efficient
closed-loop economy. Much literature has been published focusing on circular
business models and assessing environmental impact throughout the life cycle. A
move towards more circular business models, where the focus transitions to the
delivery of a capability rather than the delivery of a product, presents new
challenges to manufacturers of complex or certified engineered products. The
aviation industry has established several engineering disciplines, life cycle
design, and certification approaches that (while not designed with the circular
economy in mind) underpin the principles of the circular economy. This paper
provides a new conceptual framework for the circular economy that integrates the
engineering principles that drive circularity around the life cycle for
designing, producing, and operating complex and certified engineering systems.
It also identifies the engineering and operational principles that support the
implementation of circular economy principles for complex and certified
engineering systems, those already established, and those that would benefit
from further research and development. Then goes on to explore how these
principles, when applied by companies, industry ecosystems, and policymakers,
can underpin the move from linear to circular principles and broadly apply to
industries producing complex or certified engineering products.
