Soft sensors made of highly deformable materials are one the enabling technologies to various soft robotic systems, such as mobile robots, wearable and grippers. However, major drawbacks compared with traditional their nonlinearity hysteresis in response, which common especially microfluidic sensors. In this research, we propose address above issues by taking advantage deep learning. We implemented a hierarchical recurrent sensing network, type neural network model, calibration for...
Soft sensors are becoming more popular in wearables as a means of tracking human body motions due to their high stretchability and easy wearability. However, previous research not only was limited certain parts, but also showed problems both calibration processing the sensor signals, which caused by nonlinearity hysteresis soft materials misplacement displacement during motion. Although this problem can be alleviated through redundancy employing an increased number sensors, it will lay...
This study examined complex structural relationships among different organizational constructs affecting performance at the individual level, which included psychological- (meaningfu...
Purpose This paper aims to study the effects of perceived organizational support (POS) on employees’ knowledge sharing intention (KSI). More specifically, this examined whether these are moderated by job characteristics (JCs) and mediated citizenship behavior (OCB). Design/methodology/approach Data for 426 employees were collected via an online questionnaire from four IT companies in South Korea. Combined variable set analyzed using conditional process analyses (Hayes, 2013). Findings The...
This study examined the underlying process through which transformational leaders provide an influence on employees' knowledge sharing intention by concentrating mediating roles of psychological empowerment and commitment to organizations. The direct indirect impacts leadership were explored. In order test proposed hypotheses, structural equation modelling analysis was conducted with a sample 426 full-time employees in South Korea. results this showed significant effect organizational...
Abstract Background Attention-Deficit/Hyperactivity Disorder (ADHD) is a type of neurodevelopmental disorder characterized by inattention, impulsivity, and hyperactivity, associated with adverse long-term functional outcomes. Neurofeedback training as an add-on to medication therapy has been proposed. Aims & Objectives This study aimed evaluate the effectiveness machine learning (ML) models in predicting therapeutic response mobile neurofeedback (MNF) children diagnosed ADHD. Method: A...
A distributed virtual environment (DVE) is a software system that allows users in network to interact with each other by sharing common view of their states. As are geographically over large networks like the internet and number increases, scalability key aspect consider for real-time interaction. Various solutions have been proposed improve DVE systems but they either focused on only specific aspects or customized target application. In this paper, we classify approaches improving into five...
Purpose This study aims to examine the underlying process through which learning organization culture positively influences knowledge sharing. It specifically explored mediating role of social capital, underscoring its critical impact on enhancing both sharing and fostering culture. Design/methodology/approach To test proposed hypotheses, structural equation modeling (SEM) analysis was conducted with a sample 231 employees from manufacturing firm in South Korea. Findings The results this...
Purpose This paper aims to explore a mediating effect of self-efficacy between individuals’ informal learning and their organizational commitment. Informal individuals is critical in the workplace because sharing knowledge expertise directly related employee’s attitude benefits such as enhanced performance productivity. Of many factors affecting commitment, this research focuses on effects role self-efficacy. Design/methodology/approach To address these questions, analyzes survey data 317...
Purpose The purpose of this study is to examine the impact psychological safety on transformative learning in workplace. This focused as a specific practice that may or not independently contribute outcomes. Design/methodology/approach Data was gathered from 132 employees one US manufacturing company through survey asking about perception and experience learning. A mediation analysis conducted test effects processes – social support, attitude toward uncertainty criticality relationship...
About 80-90% of accidents are strongly associated with workers' unsafe behavior. Despite the importance worker behavior measurement, it has not been applied actively in practice due to its time-consuming and painstaking tasks. For measuring analyzing behavior, vision-based motion capture recently proposed as an emerging technique that requires no additional time or cost. In line tracking extracts 3D skeleton models from videos, this paper proposes classification techniques for automatic...
Abstract Large urban school districts often struggle with hierarchy, fragmented processes and cultures whereby organisational silos between central office staff serve as a major barrier for reaching the desired strategic goals of improving student achievement. In addition, district are undergoing change requiring leaders in these organisations to adapt build their capacity support changing demands. However, little attention is paid how necessary systems learning environments building leader...

Various solutions have been proposed improve in DVE systems but they either focused only specific aspects or customized target application. In this paper, we classify approaches improving into four...
Organizations have embraced various technologies to facilitate communications, interactions, and collaborations embody VHRD in recent years. While such integration affords opportunities for relevant HRD practices research, it neglects crucial considerations on technologies’ potential effects overloading employees’ affective cognitive processing capacities. As a result, could impede motivation perform the job. Furthermore, validate as technology-mediated processes that support organizational...
Subjective cognitive decline (SCD) refers to the self-perception of with normal performance on objective neuropsychological tests. SCD, which is first help-seeking stage and last before clinical disease stage, can be considered most appropriate time for prevention treatment. This study aimed compare characteristics between amyloid positive negative groups SCD patients.A cohort identify predictors progression mild impairment (MCI) or dementia from subjective (CoSCo) a multicenter, prospective...
Purpose Drawing on the theories of social capital and leader–member exchange (LMX), authors examined moderated mediation relationships psychological ownership perceived supervisory support organizational knowledge. Design/methodology/approach To test proposed model, collected data from 522 employees working in large corporations South Korea. Findings The found that (a) was positively related to knowledge sharing, (b) supervisor mediated linkage between sharing (c) indirect effect through...
Purpose This paper aims to focus on the relationships between situational/dispositional variables and an individual’s intention knowledge sharing, has theoretical implications for researchers in human resource development management, as well practicing managers organizations. First, this study examines whether integrative model of sharing reveals impact various antecedents individuals, which been rarely explored a single study. In particular, is interested examining two dimensions improve...
The purpose of this study was to assess the validity and reliability Transformative Learning Outcomes Processes Survey (TROPOS) in workplace context. results a confirmatory factor analysis data gathered from 132 employees steel manufacturing company United States have shown that TROPOS is an appropriate instrument for measuring transformative learning Implications research practice will be discussed.
A cavity-backed slot array antenna using a single waveguide fed sub-array is presented. subarray consists of 2/spl times/4 elements backed by cavity. By proper choice dimensions it shown that the proposed has characteristics high radiation efficiency and broad frequency bandwidth. Antenna for with 256 are measured in Ku-band.
We investigated the effects of global leadership competencies on knowledge transfer, and, in particular, moderating role self-efficacy this relationship. Participants ( N = 122) were randomly selected employees South Korean multinational corporations. They working with stakeholders and participating international competency training programs.
