The Influence Of Human Resource Policy On Job Satisfaction In Predicting Organizational Commitment
Purpose: This research aims to explore the relationship among human resource policy, job satisfaction and organizational commitment through the perception of employees working in small and medium enterprises in Vietnam.
Theoretical framework: The human resource functions and related distinct processes that help attract, develop, and retain a company's human resources. They involve employees and guide them to help carry out activities aimed at achieving organizational goals employees (Jahanian et al., 2012). Business leaders are always cautious when reviewing existing human resource policies and constantly improving to make employees satisfied with their jobs, thereby helping them improve their productivity and commitment to the organization.
Design/methodology/approach: The qualitative method is based on an overview of previous studies, the research team builds the first scale, then the questionnaire is sent to the experts and conducts a trial survey with 30 employees to control the survey, edit and complete the concepts of the questionnaire. For the quantitative research, data was collected using convenience sampling method from a total of 400 employees and managers who are working at SMEs in Viet Nam. The method of and Confirmatory Factor Analysis (CFA), Structural Equation Modeling (SEM) were carried out to measure the influence of latent variables on organizational commitment.
Findings: The research results show that employees' perceptions of HR policies include selection and recruitment; training and improvement; evaluation of employees’ tasks; stability and promotion in work, remuneration and reward, and encouragement of participation and innovation. These HR policies have a direct positive impact on job satisfaction and commitment to the organization. In addition, job satisfaction has a significant positive effect on organizational commitment. Therefore, it is necessary to improve the implementation of HR policies to promote employee job satisfaction, which helps to increase commitment to the organization.
Research, Practical & Social implications: We recommend future research that expands on other components for a comprehensive assessment of HR policies. In addition, it is necessary to analyze in detail the components of organizational commitment such as affective commitment, Continuance commitment, Normative commitment.
Originality/value: The results of standardized estimation of the parameters of the research model show that the relationship between the concepts in the formal research model is statistically significant (p<0.05). HR policies have been shown to have the most positive impact on job satisfaction in SMEs. 
A Novel Approach for Pill-Prescription Matching with GNN Assistance and Contrastive Learning
Medication mistaking is one of the risks that can result in unpredictable
consequences for patients. To mitigate this risk, we develop an automatic
system that correctly identifies pill-prescription from mobile images.
Specifically, we define a so-called pill-prescription matching task, which
attempts to match the images of the pills taken with the pills' names in the
prescription. We then propose PIMA, a novel approach using Graph Neural Network
(GNN) and contrastive learning to address the targeted problem. In particular,
GNN is used to learn the spatial correlation between the text boxes in the
prescription and thereby highlight the text boxes carrying the pill names. In
addition, contrastive learning is employed to facilitate the modeling of
cross-modal similarity between textual representations of pill names and visual
representations of pill images. We conducted extensive experiments and
demonstrated that PIMA outperforms baseline models on a real-world dataset of
pill and prescription images that we constructed. Specifically, PIMA improves
the accuracy from 19.09% to 46.95% compared to other baselines. We believe our
work can open up new opportunities to build new clinical applications and
improve medication safety and patient care.Comment: Accepted for publication and presentation at the 19th Pacific Rim

Chronic scrotal heat stress causes testicular interstitial inflammation and fibrosis: An experimental study in mice
Background: Chronic heat stress is a risk factor that adversely affects the reproduction system. Inflammation and fibrosis are 2 important response processes to damaged tissues.
Objective: This study investigates the association of chronic scrotal heat stress with testicular interstitial inflammation and fibrosis in mice.
Materials and Methods: For all experiments, 8-10 wk old male Swiss mice (Mus musculus) (20-23 gr) were divided into 3 groups (n = 10/each). The heat-stress groups were submerged in a water bath at 37°C and 40°C, while the control group was treated at 25°C. The testicular tissues underwent hematoxylin and eosin staining, picro sirius red staining, and immunohistochemistry for intercellular adhesion molecule-1, fibroblast-specific protein 1, F4/80, collagen I, and Ki-67 staining to determine the testicular interstitial inflammation and fibrosis.
Results: Chronic scrotal heat stress impairs spermatogenesis and reverses testicular histological structure. In this study, heat stress significantly induced increased interstitial cell proliferation and upregulation of intercellular adhesion molecule-1 expression in the interstitial testicular tissue. In the interstitial testicular tissue, the number of F4/80-positive macrophages and the number of fibroblast-specific protein 1- positive fibroblasts were significantly increased in the heat-exposed groups compared to those in the control group. The heat exposed groups had substantially increased extracellular matrix collagen accumulation in their testicular interstitial tissues.
Conclusion: Heat stress adversely affects the testicular structure and spermatogenesis, causes inflammation, and leads to testicular interstitial fibrosis.

zk-SNARKs from Codes with Rank Metrics
Succinct non-interactive zero-knowledge arguments of knowledge (zk-SNARKs) are a type of non-interactive proof system enabling efficient privacy-preserving proofs of membership for NP languages. A great deal of works has studied candidate constructions that are secure against quantum attackers, which are based on either lattice assumptions, or post-quantum collision-resistant hash functions. In this paper, we propose a code-based zk-SNARK scheme, whose security is based on the rank support learning (RSL) problem, a variant of the random linear code decoding problem in the rank metric.
Our construction follows the general framework of Gennaro et al. (CCS\u2718), which is based on square span programs (SSPs). Due to the fundamental differences between the hardness assumptions, our proof of security cannot apply the techniques from the lattice-based constructions, and indeed, it distinguishes itself by the use of techniques from coding theory. We also provide the scheme with a set of concrete parameters

The nexus among green financial development and renewable energy: investment in the wake of the Covid19 pandemic
Environmental protection has become a significant issue around
the globe. The extensive use of renewable energy and green
finance is considered as the solution to this dramatic issue, especially in the Covid-19 lockdown. To answer this demand, the present study examines the impact of green financial development
such as green credit, green investment, and green securities
along with corporate social responsibility (CSR) in reporting
renewable energy investment based on evidence from an emerging economy. Economic growth was used as the control variable
of the study. The data was gathered from the central bank and
World Development Indicators (WDI) from 1976 to 2020. The error
correction model (ECM) was used to test the nexus among the
variables. The findings revealed that green credit, green investment, and green securities along with CSR reporting and economic growth have a significant positive nexus with renewable
energy investment in the selected emerging economy. These outcomes are helpful for new arrivals to investigate this area in the
future along with regulators who want to formulate policies
related to green finance and renewable energy usage and investment in the context of emerging and developing countries

Study Structure and Properties of Nanocomposite Material Based on Unsaturated Polyester with Clay Modified by Poly(ethylene oxide)
In recent years, polymer clay nanocomposites have been attracting considerable interests in polymers science because of their advantages. There are many scientists who researched about this kind of material and demonstrated that when polymer matrix was added to little weight of clay, properties were enhanced considerably. Because clay is a hydrophilic substance so it is difficult to use as filler in polymer matrix having hydrophobic nature, so clay needs to be modified to become compatible with polymer. In this study, poly(ethylene oxide) was used as a new modifier for clay to replace some traditional ionic surfactants such as primary, secondary, tertiary, and quaternary alkyl ammonium or alkylphosphonium cations having the following disadvantages: disintegrate at high temperature, catalyze polymer degradation, and make nanoproducts colorific, and so forth. In order to evaluate modifying effect of poly(ethylene oxide), modified clay products were characterize d by X-ray spectrum. Then organoclay was used to prepare nanocomposite based on unsaturated polyester. Morphology and properties of nanocomposites were measure d by X-ray diffraction, transmission electron microscopy, tensile strength, and thermal stability. The results showed that clay galleries changed to intercalated state in the nanocomposites. Properties of nanocomposites were improved a lot when the loading of the organoclay was used at 1 phr
