With the globalization of economy, industries are facing increasingly greater challenges. Business integration, both internally and externally, is undoubtedly an important topic. However, how does an enterprise create its own value will be the key to an enterprise's success in the future. Therefore, this study bases on the evaluation of company value to assess the key factors and competitive strategies of an enterprise. Yet, only with stable enterprise performance can the company value be correctly evaluated. This will be an important issue for enterprise performance and business strategy. Subject of this study are mainly small and medium-sized (enterprises (SMEs). Model construction for SME value assessment is established through the system dynamics approach. Scholars' opinions on literature validation and application of Delphi Method are explored through literature review on local and foreign studies, in order to compile the relevant perspectives and indices for enterprise value creation. Hence model construction of the value creation system is established, and the correlation between the perspectives and related factors is explored to understand the overall dynamics model of SMEs' value creation system. Consequently, a research method based on the system dynamics perspective is provided for the study of enterprise value creation is provided, as policy reference for improvement of decision-making and value creation.

<P>We present the electronic characterization of single-layer 1H-TaSe2 grown by molecular beam epitaxy using a combined angle-resolved photoeinission spectroscopy, scanning tunneling microscopy/spectroscopy, and density functional theory calculations. We demonstrate that 3 x 3 charge-density-wave (CDW) order persists despite distinct changes in the low energy electronic. structure highlighted by the reduction in the number of-bands crossing the Fermi energy and the corresponding modification Of Fermi surface topology. Enhanced, spin-orbit coupling and lattice distortion in the single-layer play a crucial role in the formation of CDW order. Our findings provide a deeper understanding of the nature of COW order in the two-dimensional limit.</P>

Waterlogging is one of the major environmental challenges that can adversely impact squash growth, development, and productivity. Nevertheless, studies on the physiological changes of squash to waterlogging stress are scarce. Previously, we reported that the Cucurbita moschata (Cmo) Early Price (Ep) cultivar showed higher chlorophyll content (CC) and spectral refl ectance compared to the Cucurbita maxima (Cma) OK-101 (Ok) cultivar after waterlogging. In the present work, we further examined more physiological parameters in eight cultivars of Cmo and Cma, and studied whether these non-destruc tive indices could effi ciently identify various waterlogging-tolerant genotypes and were consistent with visual evaluations. Moreover, we investigated the eff ects of waterlogging on the antioxidant system of cucurbit species, and evaluated dynamic changes occurring in these plants during varying waterlog periods by determining physiological characteristics. The activ ity of ascorbate peroxidase (APX) and superoxide dismutase (SOD) showed a signifi cant increase in Ep plant leaves and roots after 72 h and 6 h of waterlogging, respectively, compared to Ok plants. In addition, Ep exhibited a higher tolerance to waterlogging than Ok in terms of enhanced root length, values in CC, spectral refl ectance, and APX and SOD activity, plus decreased levels of electrolyte leakage, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging, and hydrogen peroxide levels. This study provides a comprehensive understanding of the physiological variations in response to waterlogging stress and can potentially be used to breed cucurbit species with waterlogging tolerance for a wetter future climate.

Objective: Autonomic imbalance is considered a psychopathological mechanism underlying major depressive disorder (MDD). Heart rate variability (HRV) is an index for autonomic activation. Poor sleep quality is common among patients with MDD. HRV biofeedback (BF) has been used for regulating autonomic balance among patients with physical illness and mental disorders. The purpose of present study was to examine the effects of HRV-BF on depressive symptoms, sleep quality, pre-sleep arousal, and HRV indices, in patients with MDD and insomnia. Methods: In this case-controlled study, patients with MDD and Pittsburgh Sleep Quality Index (PSQI) score higher than 6 were recruited. The HRV-BF group received weekly 60-minute protocol for 6 weeks, and the control group who have matched the age and sex received medical care only. All participants were assessed on Beck Depression Inventory-II, Back Anxiety Inventory, PSQI, and Pre-Sleep Arousal Scale. Breathing rates and electrocardiography were also performed under resting state at pre-testing, and post-testing conditions and for the HRV-BF group, also at 1-month follow-up. Results: In the HRV-BF group, symptoms of depression and anxiety, sleep quality, and pre-sleep arousal were significantly improved, and increased HRV indices, compared with the control group. Moreover, in the HRV-BF group, significantly improved symptoms of depression and anxiety, decreased breathing rates, and increased HRV indices were detected at post-testing and at 1-month follow-up, compared with pre-testing values. Conclusion: This study confirmed that HRV-BF is a useful psychosocial intervention for improving autonomic balance, baroreflex, and symptoms of depression and insomnia in MDD patients.
