Selaginella austrotibetica, a new spikemoss species from China, is described. The species is epipetric and was found on a moss-covered rocky cliff by a riverbank. Morphologically, it is unlike any anisosporophyllous species in the genus Selaginella. However, it resembles species of the S. sanguinolenta group, especially similar to S. sajanensis in gross morphology, except for the characters of strobilus. The molecular phylogenetic analysis clearly showed that S. austrotibetica was nested within the anisosporophyllous species clade, forming a sister relationship with the clade of S. vaginata and S. xipholepis, and distinct from the S. sanguinolenta group, including S. sajanensis. Although S. austrotibetica is sister to the clade of S. vaginata and S. xipholepis, the species can be clearly distinguished by its sparse leaves on branches, dorsal leaves that are broad-ovate, base obtuse to rounded, margin denticulate or very shortly sparsely ciliolate, and leaves that are slightly thick and shiny. Therefore, we described Selaginella austrotibetica as a new species and discuss its phylogenetic relationships within the genus Selaginella.

Purpose: This study aims to fill the existing gap in the existing literature by investigating the mediating effect of psychological empowerment between leadership and motivation for workers at retail stores, and to extend the previous research to determine the preferences of the researchers and practitioners in leadership and employee motivation in retail through a systematic approach. Research design, data and methodology: This study used a systematic approach to the mediation effect of psychological empowerment on the relationship between leadership and employee motivation in retail stores. To ensure completeness, systematization, and transparency, the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach was applied. Results: The research findings (Total Four Mediating Roles) suggest that psychological empowerment may mediate between leadership and employee motivation. These mediation roles (Empowering Leadership Styles, Organizational Culture and Psychological Empowerment, Customer Psychological Empowerment, and High-Performance Work Systems (HPWS) and Psychological Empowerment) will help practitioners comprehend how these empowerment and motivation leadership styles are interconnected in the retail industry.

BACKGROUND/OBJECTIVES: Mushroom consumption, rich in diverse nutrients and bioactive compounds, is suggested as a potential significant contributor to preventing cardiometabolic diseases (CMDs). This systematic review aimed to explore the association between mushrooms and cardiometabolic health outcomes, utilizing data from prospective cohort studies and clinical trials focusing on the general population, with mushrooms themselves as a major exposure. SUBJECTS/METHODS: All original articles, published in English until July 2023, were identified through searches on PubMed, Ovid-Embase, and google scholar. Of 1,328 studies, we finally selected 5 prospective cohort studies and 4 clinical trials. RESULTS: Existing research is limited, typically consisting of 1 to 2 studies for each CMD and cardiometabolic condition. Examination of articles revealed suggestive associations in some cardiometabolic conditions including blood glucose (both fasting and postprandial), high-density lipoprotein cholesterol related indices, high-sensitivity C-reactive protein, and obesity indices (body weight, body mass index, and waist circumference). However, mushroom consumption showed no association with the mortality and morbidity of cardiovascular diseases, stroke, and type 2 diabetes, although there was a potentially beneficial connection with all cause-mortality, hyperuricemia, and metabolic syndrome. CONCLUSION: Due to the scarcity of available studies, drawing definitive conclusions is premature. Further comprehensive investigations are needed to clarify the precise nature and extent of this relationship before making conclusive recommendations for the general population.

Purpose: The purpose of this study is to investigate systematic and comprehensive explanation about safety behavior by applying integrated model of Theory of Planned Behavior (TPB) and Social Cognitive Theory (SCT). By showing the interrelationship of effects of factors affecting safety behavior in a single model, comprehensive understanding regarding safety behavior will be possible. Research design, data, and methodology: This study try to integrate the two theory, TPB and SCT, to introduce background factors, such as safety culture, affecting cognitive factors of subjective norm, safety attitude, perceived behavioral control, safety consciousness, which are again affecting behavior intention of the TPB. We composed 73 questionnaire to analyse the relationship among factors affecting safety behavior. The questionnaire were distributed to stewards and stewardesses of KAL, ASIANA, and LCCs. 422 were collected and used for analysis. Factor analysis, regression analysis, and control effect analysis were conducted using SPSS windows version 2.0. Results: The safety culture, safety atmosphere, and safety education/training were turned out to affect subjective norm, safety attitude, perceived behavioral control, safety consciousness. And the cognitive factors also showed to affect safety intention significantly. The results that safety intention affects safety behavior was found. Also there are control effect of cost consciousness and punishment while safety intention affects safety behavior. Conclusions: Safety is the virtue that should be given first priority to in our daily life. To secure safety, everyone in an organization should have high level of safety intention and conduct safety behavior. The study results provide systematic and comprehensive understandings on the relationship among factors affecting cabin crews' safety behavior. The results will help design safety related regulations, education/training, and support employees to engage in safety behavior related activities.

In this paper, a practical design criteria for judgement of crack occurrence in weldments is presented as a function of typical welding parameters, such as diffusible hydrogen, restraint intensity, and preheating temperature. The elastic analyses using the finite element techniques are employed in order to quantify the restraint intensities, numerically. Systematic experiments are also conducted in order to investigate the propensity of crack to typical welding parameters. The results of numerical estimation using the proposed method for the experimental specimens show the usefulness as a practical tool in welding induced crack problems with extensive uncertainties.
