In an effort to pursue a green synthesis approach, the biosynthesis of nano-silver (nAg) using plant extracts has garnered significant attention, particularly for its antimicrobial resistance and medical applications, which have been the focus of numerous studies. However, there remains a gap in surface catalytic studies, especially regarding the hydrogenation of 4-nitrophenol. While some studies have addressed catalytic kinetics, thermodynamic aspects have been largely overlooked, leaving the catalytic mechanisms of biosynthesized nAg unclear. In this context, the present work offers a straightforward, eco-friendly, and efficient protocol to obtain nano-silver inspired by Musa paradisiaca L. peel extract. This nAg serves multiple purposes, including antimicrobial resistance and as an eco-catalyst for hydrogenation. Predominantly consisting of zero-valent silver with anisotropic polyhedral shapes, mainly decahedra with an edge length of 50 nm, this nAg demonstrated effective antimicrobial action against both S. aureus and E. coli bacteria. More importantly, both kinetic and thermodynamic studies on the hydrogenation of 4-nitrophenol to 4-aminophenol catalyzed by this bio-inspired nAg revealed that the rate-limiting step is not diffusion-limited. Instead, the adsorbed hydrogen and 4-nitrophenolate react together via electron transfer on the surface of the nAg. The activation energy of 26.24 kJ mol -1 indicates a highly efficient eco-catalyst for such hydrogenation processes., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

With the development of Computer Vision, we can effectively and accurately identify trees, fruit or object images. But to build a high-performance image dataset for tree identification problems in Agriculture is a challenge. Realizing that Vietnam is a country with strong agriculture with many tropical fruits grown widely such as Dragon fruit, Mangosteen, Mango, Orange, Lychee, Longan … We chose the Dragon Fruit tree for the data set. of my proposed images, all images will be collected using the close-up method, including tasks such as taking photos of Dragon Fruit trees from many angles and in different conditions (weather, temperature, light, …). In this article, we want to improve the data quality of the collected images so we have applied image processing techniques such as noise filtering (using Gaussian filter), image quality enhancement (image rotation), flip the image, zoom out, zoom in, etc.). From the collected Dragon Fruit tree data set, we will propose to use the Faster R-CNN model for this data set to build a tree and Dragon Fruit identification system., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

In educational settings, the notion of 'achieving optimal best' in a subject matter (e.g., an elementary school student's achievement in her Year 6 Science project) is relevant for educators to consider. Optimal best, or optimal functioning, reflects the proactivity, positivity, and motivation of a person. How does a student achieve optimal best in Calculus? Our extensive research of optimal best has recognized the potency of the process of human optimization , which may operate to explain a person's successful experience and achievement of optimal best. Recently, researchers have considered another theoretical concept, which is termed as 'goals of best practice' (i.e., abbreviated as 'GsBP'). Goals of best practice, in brief, are personal goals that a person may construct and set for a particular context. Specifically, however, a 'personal goal' may indicate and espouse a person's plan of intent to either remain on course without any desire or aspiration (i.e., 'goal of actual best', denoted as 'GAB') or, alternatively, to strive for maximization (i.e., 'goal of optimal best', denoted as 'GOB'). This article is theoretical and conceptual, reflecting the use of the paradigm of philosophical psychology to advance the study of the concept of GsBP. Specifically, we contend that our conceptual analysis of GsBP, entailing both GAB and GOB may provide a logical basis and rationale for the proposition of educational implications for consideration and inquiries for continuing research development., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).)

Life education , also known as life and death education , is an important subject in Taiwan. Life education is more than just the study of a person's development throughout the lifespan (e.g., cognitive development). Within the learning and sociocultural contexts of Taiwan, interestingly, the study of life and death education is concerned with the premise of the promotion and fulfillment of life qualities (e.g., a person's state of contentment), and the meaningful understanding of the nature of death. To facilitate appreciation and deep, meaningful understanding of the subject, and to emphasize its uniqueness, educators have included in their teaching the importance of Eastern-derived philosophical beliefs and religious faiths (e.g., Buddhism). For example, relatively significant in its emphasis, the teaching of this subject involves detailed examination of theoretical accounts of spiritual cultivation and its positive effect on a person's interpretation and enlightenment of life wisdom. The study of life education, or life and death education, we contend, is of significance as it provides life-related insights and theoretical understanding into the intricate nature of life and death. One notable aspect of the subject entails a person's acquired life wisdom, which in turn may shape his/her life practice on a daily basis (e.g., the proactive engagement in Buddhist meditation). Importantly, the study of life education may assist individuals with their coping of grief, and to approach death with a sense of peace, calmness, and dignity. In this analysis, coupled with Buddhist faith (or any other religious faith for that matter) and facilitated by spiritual cultivation (e.g., the belief in the notion of transcendence experience ), a person may overcome grief by believing in the possibility that there is some form of post-death experience and the presence of a loved one's spiritual being. Given this emphasis, we consider an important focus for discussion in this article: to explore the significance of life and death education and to determine how its 'positive nature' could potentially yield two comparable implications for development: (i) to engage in appropriate pedagogical practices that would encourage and promote the study of life and death education, and (ii) to advance innovative research inquiries, theoretical, methodological, and/or empirical, which could highlight the significance of life education for life purposes (e.g., the significance of Chinese ideograms, such as )., Competing Interests: The authors declare no conflict of interest., (© 2021 The Author(s).)

We recently advanced the study of positive psychology by introducing the theory of optimization , which explains the underlying process of optimal best. Our continuing research interest has led us to a newly developed concept, termed as 'optimal efficiency'. Optimal efficiency , we contend, focuses on the utilization of resources as well as the amount of time and effort that a person would have to expend during the course of his/her learning. How much time and effort, for example, should a student expend before it is perceived as being 'inefficient'? Optimal efficiency, in this analysis, is concerned with an important relationship - namely: the minimization of expenditure of time, effort, resources, etc. versus the maximization in productivity. Perceived efficiency is related to the teaching and training of judgment, decision making, autonomy, and self-determination - for example, in terms of successful schooling, a student has to decide whether it is worthwhile to expend so much time and effort on a given task when he/she may not necessarily pass. In our conceptual analysis and proposition of optimal efficiency, we consider the impact of cognitive load theory , which places emphasis on calculated investment and subsequent use of cognitive resources to process information for the purpose of achieving effective learning in a subject matter. Using cognitive load theory as a basis, we attempt to validate the concept of optimal efficiency by taking into account three main types of cognitive load imposition: extraneous, intrinsic, and germane. For example, we consider the possibility that a reduction in extraneous cognitive load imposition could instill a perception of efficiency, resulting in a person's achievement of optimal best. Emphasis on encouragement of germane cognitive load, in contrast, could be perceived as being more efficient, likewise yielding exceptional outcomes in a subject matter., Competing Interests: The authors declare no conflict of interest., (© 2021 The Author(s).)

Positive psychology has attracted extensive interests from educators, researchers, and organizations. Many would recognize the work of Martin Seligman (e.g., Seligman, 2010) and Mihaly Csikszentmihalyi (e.g.,Csíkszentmihályi, 2014b). In its summarized form, positive psychology is concerned with a person's state of flourishing, his/her perceived sense of resilience and inner virtues, and a desire to have positive outlooks in life. Positive psychology is significant, forming the basis for other research inquiries - for example, the advancement of the theory of optimization (Fraillon, 2004; Phan, Ngu and Yeung, 2019b). Considering this evidence, we develop and offer an alternative theoretical model for discussion, which we termed as 'holistic psychology'. Holistic psychology , the main focus of this theoretical-conceptual article, is significant for its emphasis on the existence of life experiences, which may exist on a continuous spectrum without distinction between negativity and positivity. This testament, we contend, reflects the importance of inclusiveness and that one could consider maladaptive and negative life experiences (e.g., school disengagement) as sources of vitality, motivating and governing a person to seek for improvement, resulting in a state of flourishing. Our conceptualization in this sense is philosophical, grounded in the main premise of optimization (Fraillon, 2004; Phan et al., 2019b) in which we propose a key tenet for consideration - namely, the 'transformation' of negative life experiences into a source of 'energy' (i.e., denoted as E) for subsequent enactment. In detail for discussion, our proposed model of holistic psychology consists of four major stages: (i) personal reflection, (ii) the sub-process of transformation, (iii) enactment of energy, and (iv) arousal and sustaining an improved state of functioning., (© 2020 The Author(s).)

Predicting and enhancing positive emotions, reflecting the tenets of positive psychology, is of considerable importance for educators. Positive emotions may consist of a person's indication of happiness, joy, and love. In school and university settings, as research has shown, positive emotions play a pivotal role in helping students adjust, make friends, and engage in proactive social relationships with others. It is imperative for us to consider the design and development of educational programs that could assist in the facilitation of positive emotions. The present study involved examination of an inquiry into the prediction of positive emotion of university students, via means of data drawn from Taiwan. The main question for consideration is to determine the extent to which both social (e.g., the social milieu) and personal (e.g., personal resolve) influences could predict positive emotions. Structural equation modelling yielded support for our proposed a priori model: (a) the direct predictive effects of the social milieu, personal resolve, relating to others, and academic liking experience, and (b) the potential mediating roles of relating to others, and academic liking experience. Overall, the concept of emotions plays a central role and is accounted for by different types of personal and social contextual influences., (© 2019 The Author(s).)
