To systematize knowledge management process for future computer-aided DR applications, a prerequisite is to provide the measure for the DR knowledge. In this paper, a new knowledge network evaluation method for DR management is presented. The method characterizes the DR knowledge value from four perspectives, namely, the design rationale structure scale, association knowledge and reasoning ability, degree of design justification support and degree of knowledge representation conciseness. The DR knowledge comprehensive value is also measured by the proposed method. To validate the proposed method, different style of DR knowledge network and the performance of the proposed measure are discussed. The evaluation method has been applied in two realistic design cases and compared with the structural measures. The research proposes the DR knowledge evaluation method which can provide object metric and selection basis for the DR knowledge reuse during the product design process. In addition, the method is proved to be more effective guidance and support for the application and management of DR knowledge.展开更多

It must be incorporated and applied all throughout the nursing process. The impact of patients’ positive outcomes relies on how nurses are effective in clinical reasoning and put into action once clinical decision making occurs. Thus, nurses with poor clinical reasoning skills frequently fail to see and notice patient worsening condition, and misguided decision making arises that leads to ineffective patient care and adding patients suffering. Clinical judgment on the other hand denotes on the outcome after the cycle of clinical reasoning. Within this context, nurses apply reflection about their actions from the clinical decision making they made. The process of applying knowledge, skills and expertise in the clinical field through clinical reasoning is the work of art in the nursing profession in promoting patient safety in the course of delivering routine nursing interventions. Nurses must be guided with their sound clinical reasoning to have an optimistic outcome and prevent iatrogenic harm to patients. Nurses must be equipped with knowledge, skills, attitude and values but most importantly prepared to face the bigger picture of responsibility to care for every patient in the clinical field.展开更多

A project Mem-ory concerns the representation and the identification of the experience acquired during projects realization. The main feature of this approach is that the semantic annotation is used to build a continuous semantic design rationale process. We propose in this paper, a semantic traceability in four stages (identifying, structuring, annotating and integrating). The identification and the structuring phases use a model called Extended Marguerite model which fully considers the objectives of the project memory. The annotation phase exploits the results of precedent phase to prepare the final phase. Examples are presented from a case study in an Algerian firm called ENMTP. The architecture supporting the modelling engine is presented. Finally, an evaluation of the degree of the semantic annotation brought by proposed process is given.展开更多

A number of jurisdictions, including China, are considering the approach that they will adopt. This article seeks firstly to consider the justifications for the legal recognition of same-sex relationships by the state. Three main, compelling rationales are identified which are rooted in notions of the equality of all persons, the dignity and liberty of individuals to form close personal relationships, and the social benefits of recognizing close, personal relationships of same-sex couples. The second part of this article then turns to consider the maimer in which same-sex relationships should be recognized. Four models are identified： a ＂Partial Rights＂ model; a ＂Civil Partnerships＂ model; a ＂Marriage Equality＂ model, and a ＂Diversity of Relationships＂ model. Reasons for and against these particular models will be examined. In the conclusion, it shall be argued that the choice of model that has been adopted can be seen to depend on a number of factors： the manner in which equality is conceived in that society; the understanding of same-sex relationships therein, and the religious and cultural opposition to same-sex relationships in that society. The models are also not states of affairs that are fixed for all time and many countries have progressed from less extensive forms of recognition to wider recognition over time. Ultimately, it shall be argued that the rationales underlying the recognition of close personal relationships in the law support the ＂Marriage Equality＂ model or the ＂Diversity of Relationships＂ model. This article thus seeks to provide an understanding of the rationales and models for recognizing same-sex relationships that have been adopted around the world： Its focus is thus comparative but may, in this way, be useful to lawmakers and advocates for legal reform in this area in China and other jurisdictions around the world.展开更多

文摘Carotenoid cleavage dioxygenase 4(CCD4)controls the rate-limiting step ofβ-ionone biosynthesis,making it a valuable target for healthcare and pharmaceutical applications.Nicotiana tabacum,a carotenoid-richd crop species,is a promising source forβ-ionone production.This study aimed to modify CCD4 activity to increaseβ-ionone yield in tobacco.We identified two isoforms of CCD4 in N.tabacum,NtCCD4a and NtCCD4b,with NtCCD4a exhibiting significantly higher expression levels than NtCCD4b.Using solid-phase microextraction gas chromatography-mass spectrometry(SPME-GC–MS),we demonstrated that NtCCD4a effectively catalyzes the cleavage ofβ-carotene to produceβ-ionone.To improve its enzymatic activity,we applied structure-based rational design to reconstruct the active pocket of NtCCD4a,followed by high-throughput screening of mutant variants.Three single base mutants,F181G,F184L,and F337M,in NtCCD4a showed enhancedβ-ionone production compared to the wild-type,with F337M yielding the highest amount.No synergistic effects were observed among the three mutants.Transgenic tobacco plants expressing the F181G,F184L,and F337M mutations had acceleratedβ-carotene cleavage and increasedβ-ionone production relative to the wild-type NtCCD4a.Our results establish a framework for the design of CCD4 in major crop species through genome editing technology.

文摘The von Hippel-Lindau tumor suppressor(VHL)has been extensively used to develop degraders targeting numerous proteins of interest.However,studies on the rational design of VHL-proteolysis-targeting chimeras(PROTACs)remain scarce.This study aimed to develop strategies to investigate VHL-recruiting PROTACs connecting with varying attachment sites on VHL ligands,which could be utilized for KRAS^(G12C) degraders development and expanded to additional targets.We developed a molecular dynamics(MD)-based strategy to explore the stability of ternary complexes induced by KRAS^(G12C) PROTACs with four distinct attachment sites of VH032.We found a potent degrader namely YN14-H,linked to hydroxyl group on VH032 benzene ring,exhibited the most superior ability of inducing ternary complexes,reflected by the lowest dissociation constant(Kd)for ternary complex induction and the highest AlphaScreen(AS)-based interaction.YN14-H inhibited cell growth with low nanomolar half maximal inhibitory concentration(IC_(50))and half maximal degradation concentration(DC_(50))values as well as>98%of maximum degradation(D_(max))in NCI-H358 and MIA PaCa-2 cells harboring KRAS^(G12C)-mutation.Mechanistically,YN14-H significantly induced apoptosis and inhibited the migratory capacity.Notably,YN14-H demonstrated favorable pharmacokinetic properties and excellent antitumor activity in vivo.Furthermore,bromodomain-containing protein 7(BRD7)and Bruton tyrosine kinase(BTK)degraders attached to distinct sites on VH032 further verified the rationality and universality of our MD-based strategies.Our findings demonstrated that YN14-H could serve as a promising candidate for the treatment of tumors with KRAS^(G12C)-mutation and present a strategy for the rational design of VHL-recruiting PROTACs that target additional proteins at distinct attachment sites.
文摘This paper is a product of intensive reading teaching reform practice held in Shantou Universityin 1998,under the instruction of Mr.Black(professor of New York City University).It summarises therational and procedures we used in the teaching practice of intensive reading.Modes of top-down and bot-tom-up processing are introduced,procedures such as skimming,scanning,careful reading,writing,role-playing,presentation and practice are described,particular importance is attached to group work orpair work.The rationale and procedures we put forward in this paper are not revolutionary but a combi-nation of traditional Chinese teacher-centred mode with contemporary western student-centred approachin the teaching of intensive reading in China.However,they have been proved highly efficient and prac-tical,which makes this paper worth reading.

文摘Injection sclerotherapy is most effective for internal hemorrhoids,especially for patients with bleeding.Howev-er,traditional sclerotherapy via anoscope may cause iatrogenic risk and complications due to misplaced injections.[1]The flexible endoscopic sclerotherapy for internal hemorrhoids using a short needle without cap assistant was first reported in 1991 in the United States.[2]The flexible endoscopic injection using a short needle with cap assistant was reported in 2014 in Japan.[3]Cap-assisted endoscopic sclerotherapy(CAES)primarily using a long needle was reported in 2015[4]as an emerging flexible endoscopic therapy,and has been widely used for internal hemorrhoids and some prolapse in China.A panel of experts aimed to develop expert recommendations for CAES and derived guidelines on the key issues in hemorrhoidal disease,including rationale,new positioning methods for anus,indications,contraindications,techniques,post-procedure management,and core outcome set for evaluation[Figure 1].
