To better understand Nonaka’s SECI model of knowledge creation and its constraints, we revisit the fundamental points of tacit knowledge in the model and provide a critical review on the role of tacit knowledge in business organization. First, the “tacitness” of knowledge is broken down into two parts: implicitness and real tacitness. We argue that the tacit dimension of knowledge in the context of the model is different from that in Polanyi’s original context; it actually includes considerable “implicitness” idiosyncratic in Japanese context. The separation of implicitness from real tacitness suggests carefully considering the potentialities of “unveiling” the secrets of tacit knowledge in different contexts. Second, considering most cases for the model mainly came from certain Japanese manufacturing companies that more or less relates to assemble lines, it is necessary to be cautious when the model is extended for a broader application.

The outbreak of infectious diseases such as COVID-19 causes an urgent need for abundant personal protective equipment (PPE) which leads to a huge shortage of raw materials. Additionally, the inappropriate disposal and sterilization of PPE may result in a high risk of cross-contamination. Therefore, the exploration of antimicrobial materials possessing both microbe interception and self-decontamination effects to develop reusable and easy-to-sterilize PPE is of great importance. Herein, an aggregation-induced emission (AIE)-active luminogen-loaded nanofibrous membrane (TTVB@NM) sharing sunlight-triggered photodynamic/photothermal anti-pathogen functions are prepared using the electrospinning technique. Thanks to its porous nanostructure, TTVB@NM shows excellent interception effects toward ultrafine particles and pathogenic aerosols. Benefiting from the superior photophysical properties of the AIE-active dopants, TTVB@NM exhibits integrated properties of wide absorption in visible light range, efficient ROS generation, and moderate photothermal conversion performance. A series of antimicrobial evaluations reveal that TTVB@NM could effectively inactivate pathogenic aerosols containing bacteria (inhibition rate: >99%), fungi (~88%), and viruses (>99%) within only 10 min sunlight irradiation. This study represents a new strategy to construct reusable and easy-to-sterilize hybrid materials for potential bioprotective applications.

Bioprinting is one of several newly emerged tissue engineering strategies that hold great promise in alleviating of organ shortage crisis. To date, a range of living biological constructs have already been fabricated in vitro using this technology. However, an in vitro approach may have several intrinsic limitations regarding its clinical applicability in some cases. A possible solution is in vivo bioprinting, in which the de novo tissues/organs are to be directly fabricated and positioned at the damaged site in the living body. This strategy would be particularly effective in the treatment of tissues/organs that can be safely arrested and immobilized during bioprinting. Proof-of-concept studies on in vivo bioprinting have been reported recently, on the basis of which this paper reviews the current state-of-the-art bioprinting technologies with a particular focus on their advantages and challenges for the in vivo application.

KM is increasingly imperative as it is regarded as the key determinant of a firm, industry or country for survival and growth in knowledge era. Varieties of disciplines have made contributions to knowledge and knowledge management. Research focuses on one or more specific fields, but to understand which levels of knowledge processes knowledge management should concentrate on, should be more fundamental than advocacy of knowledge management. Knowledge-related matters were examined from the viewpoint of systems science. Using critical systems thinking, soft systems thinking etc., a new systematic perspective on knowledge was proposed, aiming to provide a new way of thinking and a useful toolbox on different levels and phases of knowledge management for practical knowledge users.

Background: Lung cancer is very common in China. The low cure rate, limited overall survival, and continuous therapies lead the patients to experience considerable psychological distress. Traditional Chinese medicine therapy is one unique treatment method in China. Nevertheless, most patients in the existing studies on anxiety and depression were treated in western medical hospitals. Therefore, it is necessary to identify the prevalence and risk factors of these emotional disorders in lung cancer patients treated in traditional Chinese medical hospitals. These findings may assist in clinical intervention. Patients and methods: A total of 315 patients with lung cancer were enrolled. Individuals completed the Hospital Anxiety and Depression Scale to assess their levels of anxiety and depression. Demographic and clinical data were also collected. Binary logistic regression analysis was used to identify factors that significantly predicted anxiety and depression. Results: The anxiety and depression prevalence rates of lung cancer patients were 43.5% and 57.1%, respectively. In the univariate analysis, patients without surgery, who were young, or who received radiotherapy were more likely to experience anxiety. Patients without surgery, who were young, or who had late-stage cancer, were more likely to experience depression. Binary logistic regression analysis showed that the risk factors of both anxiety and depression were lack of surgery and young and middle age (＜65, especially 45–65 years). Conclusion: Anxiety and depression were very common in lung cancer patients. Lack of surgery, young, and middle age, were independent risk factors for anxiety and depression. Therefore, medical workers should pay close attention to the emotional changes of young or middle-aged patients, or patients without the chance to undergo surgery.

Magnolia zenii is a critically endangered species known from only 18 trees that survive on Baohua Mountain in Jiangsu province, China. Little information is available regarding its molecular biology, with no genomic study performed on M. zenii until now. We determined the complete plastid genome of M. zenii and identified microsatellites. Whole sequence alignment and phylogenetic analysis using BI and ML methods were also conducted. The plastome of M. zenii was 160,048 bp long with 39.2% GC content and included a pair of inverted repeats (IRs) of 26,596 bp that separated a large single-copy (LSC) region of 88,098 bp and a small single-copy (SSC) region of 18,757 bp. One hundred thirty genes were identified, of which 79 were protein-coding genes, 37 were transfer RNAs, and eight were ribosomal RNAs. Thirty seven simple sequence repeats (SSRs) were also identified. Comparative analyses of genome structure and sequence data of closely-related species revealed five mutation hotspots, useful for future phylogenetic research. Magnolia zenii was placed as sister to M. biondii with strong support in all analyses. Overall, this study providing M. zenii genomic resources will be beneficial for the evolutionary study and phylogenetic reconstruction of Magnoliaceae.

The inevitable bleeding during tumor resection greatly increases the risk of tumor recurrence caused by metastasis of cancer cells with blood, and hemostasis and prevention of post‐operation tumor recurrence is still a challenge. However, a biomaterials approach for rapid hemostasis during tumor resection and simultaneous prevention of tumor recurrence is rarely reported. Here, zeolitic imidazolate framework (ZIF‐8) nanoparticle‐enhanced multinetwork cryogels are proposed which provide an integrated treatment regimen for rapid hemostasis through intraoperative blood trigger shape recovery and enhanced coagulation, and prevention of postoperative cancer recurrence via sonodynamic anticancer in a hepatocellular carcinoma model. A series of antibacterial shape memory multifunctional cryogels are synthesized based on glycidyl methacrylate‐functionalized quaternized chitosan (QCSG), dopamine‐modified hyaluronic acid (HA‐DA), and hematoporphyrin monomethyl ether (HMME)‐loaded dopamine‐modified ZIF‐8 (ZDH). Blood loss in different bleeding models confirms good hemostasis of ZIF‐8 loading cryogels. Besides, in vitro tests confirm that QCSG/HA‐DA/ZDH (QH/ZDH) cryogels significantly killed cancer cells by generating reactive oxygen species under ultrasound. Finally, significantly reduced tumor recurrence after the resection of ectopic hepatocellular carcinoma further confirms the good effect of QH/ZDH cryogels in preventing recurrence by a coordinated strategy of intraoperative hemostasis and postoperative sonodynamic therapy by pH‐responsive HMME release, showing great potential in clinical application.
