The purpose of this study is to investigate the mediating role of proactive behaviors in the mechanism which job crafting affects organizational effectiveness. Through this study, we tried to contribute to the following theoretical and practical aspects. First, we tried to extend the theoretical discussion by identifying the relationship between job crafting, proactive behavior, and organizational effectiveness. Second, we provide practical implications for Korean organizational members based on proven job crafting, proactive behavior, and organizational effectiveness, and contribute to creating a work environment that enhances job satisfaction and reduces turnover intention. The results of this study are as follows. First, increasing structural job resource, increasing social job resource and increasing challenging job demand, which are sub-factors of job crafting, had a positive effect on job satisfaction. Second, increasing structural job resource, increasing social job resource and increasing challenging job demand, which are sub-factors of job crafting, had a negative effect on turnover intention. Third, job crafting had a positive effect on proactive behavior. Fourth, proactive behavior mediated the relationship of increasing structural job resource, increasing social job resource, increasing challenging job demand, and job satisfaction. Fifth, proactive behavior mediated the relationship of increasing structural job resource, increasing social job resource and turnover intention. This study provides an understanding of the impact of job crafting on organizational effectiveness and is expected to contribute to future research on job crafting.

Individuals with special needs include those with behavioral issues, developmental disorders, cognitive disorders, congenital or genetic disorders, or systemic disease. These conditions may place them at increased risk for oral diseases. Dental management of patients with special needs require in-depth understanding of the background of disability and available behavioral guidance theories. Therefore dental team members need more training in the theory and practice of behavior management principles, which might lead to a clinical experience that is more respectful of the dignity and independence of patients with special needs. The dental professional should be flexible to modify the behavior management approach according to the individual patients needs. Also a family/care-giver centered approach based on their preferences and concerns, the patient's challenging behaviors, and related medical problem can serve to improve the treatment planning and oral health management of dental patients with special needs. This article focuses on uncooperative behavior and behavior management, which help practicing dentists to understand their role in the care of patients with special needs.

Surveillance systems play a pivotal role in ensuring the safety and security of various environments, including public spaces, critical infrastructure, and private properties. However, detecting abnormal human behavior in lowlight conditions is a critical yet challenging task due to the inherent limitations of visual data acquisition in such scenarios. This paper introduces a spatiotemporal framework designed to address the unique challenges posed by low-light environments, enhancing the accuracy and efficiency of human abnormality detection in surveillance camera systems. We proposed the pre-processing using lightweight exposure correction, patched frames pose estimation, and optical flow to extract the human behavior flow through t-seconds of frames. After that, we train the estimated-action-flow into autoencoder for abnormal behavior classification to get normal loss as metrics decision for normal/abnormal behavior.

Design and maintenance of large span roof structures require an analysis of their static and dynamic behavior depending on the physical parameters defining the structures. Therefore, it is highly desirable to estimate the parameters from observations of the system. In this paper we study the parameter estimation problem for damped shallow arches. We discuss both symmetric and non-symmetric shapes and loads, and provide theoretical and numerical studies of the model behavior. Our study of the behavior of such structures shows that it is greatly affected by the existence of critical parameters. A small change in such parameters causes a significant change in the model behavior. The presence of the critical parameters makes it challenging to obtain good estimation. We overcome this difficulty by presenting the Parameter Estimation Algorithm that identifies the unknown parameters sequentially. It is shown numerically that the algorithm achieves a successful parameter estimation for models defined by arbitrary parameters, including the critical ones.

Immune system is composed of multiple cells with distinct functions, and immune responses are orchestrated by complex and dynamic cell-cell interactions. Therefore, each cell behavior and function should be understood under right spatio-temporal context. Studying such complexity and dynamics has been challenging with conventional biological tools. Recent development of new technologies such as state of art imaging instruments and microfabrication techniques compatible with biological systems have provided many exciting opportunities to dissect complex and dynamic immune cell interactions; new microscopy techniques enable us to observe stunning dynamics of immune system in real time. Microfabrication permits us to manipulate microenvironments governing molecular/cellular dynamics of immune cells to study detailed mechanisms of phenomena observed by microscopy. Also, microfabrication can be used to engineer microenvironments optimal for specific imaging techniques. In this presentation, I am going to present an example of how these two techniques can be combined to tackle challenging problems in immunology. Obviously, this strategy can readily be applied to many different fields of biology other than immunology.

The purpose of this study was validate the Preschool and Kindergarten Behavior Scale-2(PKBS-2) and develop the Korean version PKBS-2(K-PKBS-2) through the phases of concept and statistical review. For this purpose, this study conducted PKBS-2 for teachers with 1,119 young children in Jeonbuk province. During the factor structure review, according to the results of exploratory factor analysis, 30 items and 4 factors(social interaction, social cooperation, social compliance, and social independence) in social skills scale and 40 items and 4 sub-factors of 3 factors(internalizing behavior, externalizing behavior, and interpersonal emotional behavior) in problem behavior scale were extracted. In addition, confirmatory factor analysis, the model fits of social skills and problem behavior scales were higher than the original test and very high reliability and internal consistency were produced. During external factor review, convergent validity and discriminant validity were verified. After cultural specificity and cultural universality between PKBS-2 and K-PKBS-2 were discussed, K-PKBS-2 was presented as e scale which is very useful for the screening, prevention, and intervention program plan of challenging behavior behaviors in young children in Korea.

In today's highly unpredictable marketing environment, where the consumer demands and behaviors are continuously and rapidly changing therefore various factors of consumer impulse buying behavior are proving to be challenging for the existing and new business organizations. Shopping has become a relaxing and rejoicing activity for the consumers making impulsive buying as a socially acceptable and common practice. So by taking into account all these aspects, the objective of this study was to understand the factors affecting impulse buying behavior of the consumer. Store atmosphere and fashion involvement were selected as independent variables while consumer impulse buying behavior was taken as dependent variable for this study. Likewise, impulse buying behavior of consumers with different monthly household income was also analyzed in this study. Primary data was collected through a questionnaire from 250 respondents of district Faisalabad, and then it was analyzed by using various statistical techniques. The results indicated a significant positive impact of store atmosphere and fashion involvement on consumer impulse buying behavior. The study also revealed that among consumer groups with different household incomes; at least one group differed from others in impulse buying behavior. These results were consistent with previous literature. These results could provide information to the marketers and retailers for planning and execution of various marketing techniques. Moreover, educators could expand on the findings by developing new studies examining consumer impulse buying behavior.

Developing accurate prediction models for deterioration behavior represents a challenging but essential task in comprehensive Infrastructure Management Systems. The challenge may be a result of the lack of historical data, impact of unforeseen parameters, and/or the past repair/maintenance practices. These realities contribute heavily to the noticeable variability in deterioration behavior even among similar components. This paper introduces a novel approach to predict the deterioration of any infrastructure component. The approach is general as it fits any component, however the prediction is custom for a specific item to consider the inherent impacts of expected and unexpected parameters that affect its unique deterioration behavior.

Discrete event systems interact with the external environment to decide which action plan is adequate. Some of these interactions are not predictable in the modelling phase and require consequently an adaptation of the system to the metamorphosed behavior of the environment. One of the challenging issues is to guarantee safety behavior when failures tend to derive the system from normal status. In this paper we propose a framework to combine diagnose technique with adaptive control to avoid unsafe sate an maintain the normal behavior as long as possible.
