Converting customer needs into specific forms and providing consumers with services are crucial in product design.Currently,conversion is no longer difficult due to the development of modern technology,and various measures can be applied for product realization,thus increasing the complexity of analysis and evaluation in the design process.The focus of the design process has thus shifted from problem solving to minimizing the total amount of information content.This paper presents a New Hybrid Axiomatic Design(AD)Methodology based on iteratively matching and merging design parameters that meet the independence axiom and attribute constraints by applying trimming technology,the ideal final results,and technology evolution theory.The proposed method minimizes the total amount of information content and improves the design quality.Finally,a case study of a rehabilitation robot design for hemiplegic patients is presented.The results indicate that the iterative matching and merging of related attributes can minimize the total amount of information content,reduce the cost,and improve design efficiency.Additionally,evolutionary technology prediction can ensure product novelty and improve market competitiveness.The methodology provides an excellent way to design a new(or improved)product. 展开更多

Combined with equipment activities such as combat readiness,training, exercises and management, it is proposed that the design of equipment in-service assessment subjects should follow the principles of combination, stage and operability. Focusing on the design of equipment in-serviceassessment subjects, a design method for in-service assessment subjects basedon the combination of trial and training mode is proposed. Based on theactual use of high-equipment use management and training and the established indicator system, the army’s bottom-level equipment activity subjectsand bottom-level assessments are combined. The indicators are mapped andanalyzed. Through multiple rounds of iterations, the mapping relationshipbetween in-service assessment indicators and military equipment activitysubjects is established. Finally, the equipment activity subjects whose data iscollected (reflecting the underlying assessment indicators) are generated inservice assessment subjects. The orthogonal test method is used to optimizethe samples in the assessment subjects to form an in-service assessmentimplementation plan. Taking a certain type of armored infantry fightingvehicle as an example, the sample optimization design of the initially generatedin-service assessment subjects is analyzed. It provides methods and ideas tocarry out in-service assessment work. 展开更多

Actually recent investigation in developing semiconducting-superconducting composites based in CdS and Bi-based superconductors has attracted interest in processing thin superconducting films. In this work are reported Bi-Pb-Sr-Ca-Cu-O (BPSCCO) thin films grown on MgO substrates by spray pyrolysis technique from a solution containing Bi(NO3)3, Pb(NO3)2, Sr(NO3)2, Ca(NO3)2 and Cu(NO3)2, with a subsequent solid state reaction for growing the Bi-based superconducting phases. Annealed films were characterized by X-ray diffraction, atomic absorption spectroscopy and resistance measurements. Interdependence between Pb content, annealing time and temperature, in the formation of superconducting phases was studied applying a fractional factorial design 3III4-2. Interrelation between Pb content, ta and Ta exists. The presence of Pb is necessary to stabilize the high-Tc phase but its content depends on the annealing conditions. 展开更多

Objective: To explore the feasibility of the nurse’ s prescription right in China, to develop the requirements for the qualification of the ap-plicant for the prescription right of nurse, and to determine the content of certain prescriptions in the specific circumstances. Methods: Literature review on the relevant articles/material with the contents of the nurse’ s right of prescription home and a-broad. Semi-structured depth interview method was used to interview 18 experts on whether the nurses can participate in the graded nursing decision and whether nurses with certain ability can make the decision. Using the self-made questionnaire“Nur-ses involved in graded nursing decision-recognition questionnaire”, 553 nurses completed questionnaires on willingness to nurse decision-making grading. Using the analytic hierarchy process, the 23 experts’ judgment on the main body of the graded nurs-ing was rated. Using semi-structured depth interview method, 17 experts were interviewed on the graded nursing quality assess-ment and training outline. The form of expert personal judgment and the“grading nursing qualification experts predict question-naire”were used as a preliminary designing tool, 32 experts were asked to predict the graded nursing quality. The relatively im-portant factors that might promote implementation of right of Chinese nurse prescribing weights setting were obtained by analytic hierarchy process. Using Delphi method, 2 rounds of consultation to 291 experts/times were performed, and determined its con-tent on the fields of graded nursing decision, nurses’ job description, decision making nurse in graded nursing work process and related management system, decision-making main body of clinical nursing, nurse authority of prescription application qualifi-cation, clinical nurses, diabetes specialist nurses, tumor specialist nurses, nurses in emergency department, community nurses in certain circumstances writing prescription, and nursing undergraduate added with nurse authority of prescription related courses. Results: The physician is not considered to be the best decision-making main body of clinical nursing work and graded nurs-ing, nurses can participate in the work of decision-making. The qualification of hierarchical decision-making nurse and nurse prescribing applicants have been determined. The hierarchical nursing decision-making nurses’ position description and training outline have been compiled. Experts suggest that clinical nurses with certain qualifications should be given the rights of some prescription form ( independent prescription, prescription, prescription protocol extension) to prescribe specific drugs in high fe-ver, hypoglycemia, hypertension, anaphylactic shock and other 11 specific circumstances. The nurses of the diabetes should be given the right of prescribing sulfonylureas, biguanides, glucosidase inhibitor, and protamine zinc insulin, and the right to write the prescription and consultation for part of medical equipment, health education, and four routine tests, which contains blood sugar monitoring, urine glucose monitoring, glycosylated hemoglobin assay, and oral glucose tolerance test. Tumor specialist nurses should be given the right to write the prescription of 7 specific circumstances including blood routine tests, electrocardio-gram, blood biochemistry and other 9 laboratory tests, constipation, phlebitis, and cancer pain, and the right of 5 tumor emer-gency prescription including chemotherapy drug allergy, hemorrhagic shock, acute upper gastrointestinal bleeding. Nurses in e-mergency department with certain qualification should be given the right to prescribe specific drugs in 15 circumstances which include cardiac arrest, ventricular fibrillation, and acute cardiogenic chest pain. Community nurses with certain qualification should be given the right to write the prescriptions on 14 contents including disinfection and cleaning, sterile infusion type, and wound care products. Experts suggest that nursing undergraduate education in China should be added with 2 courses which are prescription rights related laws and regulations and nursing intervention, and that pharmacology course should be supplemented with related course in order to adapt to the implementation of nurse prescribing rights. Conclusions: China’ s nurses with certain qualification or after special training have the ability to accept and should be given the right of prescriptions in certain circumstance within the scope of their work. 展开更多

As professors are subjected to teaching their classes online due to the recent COVID-19, our local Hong Kong students find it difficult to consult their teachers, and ultimately would fail to achieve the intended learning outcomes, especially for practical-based subjects. In this research, students having online classes of a practical-based fabric design subject were encouraged to self-study from Open Educational Resource (OER) materials for a further and better understanding of their subject. Additionally, online materials were developed to improve students’ understanding via skill of digital literacy. Their learning progress was evaluated and compared to the face-to-face version. The majority of students found online classes combined with self-studying OER materials, potentially be a substitute for face-to-face classes. Most of the students further opined different OER videos assisted them without any face-to-face instructions in practical works, to develop new fabric samples from the inspiration. Analysis of test results, and comparison of students’ final grades with different learning modes, supported these phenomena. 展开更多

The key issues and challenges facing TEFL teachers in China with respect to prospective teacher preparation and professional development are discussed. Drawing upon earlier research on conceptual frameworks, the knowledge base of pre-service teachers is examined through research into the curriculums in TEFL education across diploma, undergraduate and postgraduate levels. A comparative study of the curriculum structures in the education of TEFL teachers reveals a number of key areas of concern: the main hindrance to the development of a stronger knowledge base of pre-service teachers lies in the serious shortage of pedagogical content knowledge, fundamental pedagogical knowledge that are currently available, as well as with the overall inadequacy of practicum hours. It strongly argues for the breadth versus depth in course design and calls for the imperative to reconceptualize the knowledge base of pre-service teachers. 展开更多

The relationship between design and science in architecture continually receives attention from scholars,but to our knowledge,no substantial and systematic literature reviews have been undertaken to generate insights into how the relationship between the two has developed in recent times.As most of the related debate remains theoretical,this paper presents evidence acquired through content analysis of selected 782 peer-reviewed papers published in the last four decades,a period in which design requirements continue to grow in complexity and research efforts increasingly concentrate on design methods.In response,this study departs from the two keywords,architectural science and building science,and develops search strings to support examination of the relationship between science and architectural design since the 1980s,when research that addresses the building environment started to intensify.The analysis employs tools based on machine learning algorithms for text analytics in combination with traditional content analysis methods.The presented research method is fully replicable and stands as one of the contributions of this study.The findings capture the expansion of the research context concerned with the built environment through a careful selection of defining terms,and generate an informed discussion on how the role of science in the architectural design process has changed. 展开更多

Objective: To optimize the ionic liquid based microwave-assisted extraction (IL-MAE) of polyphenolic content from Peperomia pellucida (L) Kunth. Methods: The IL-MAE factors as experimental design parameters, including microwave power, extraction time, ionic liquid concentration, and liquid–solid ratio had been involved. Response surface methodology and Box–Behnken design were used to obtain predictive model (multivariate quadratic regression equation) and optimization of the extraction process. The response surface was analyzed by using the yields of total polyphenolic content as response value. Results: Based on the obtained results the optimum extraction condition, including microwave power of 30% Watts, extraction time of 18.5 min, the ionic liquid concen-tration of 0.79 mol/L, and the liquid–solid ratio of 10.72 mL/g 1-Buthyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) as a solvent was selected. The regression model was obtained to predicts the yields from Peperomia pellucida:Y = 30.250 – 1.356X1 + 2.655X2 + 2.252X3 – 0.565X4 + 0.990 X1X3 – 8.172 X1X4 – 3.439 X3X4 – 4.178 X12 – 3.210 X32 – 6.786 X42 – 7.290 X12X3 + 5.575 X1X32 – 4.843 X32X4 with R2 = 0.82519. Scale-up confirmation test was obtained the maximum yields of total polyphenolics content with the amount of 31.1725μg GAE/g. Conclusions: The IL-MAE method produced a higher extraction polyphenolic and performed rapidly, easily and efficiently. 展开更多

Critical rainfall estimation for early warning of rainstorm-induced flash flood is an inverse rainstorm-runoff process based on warning discharge threshold for a warning station of interest in a watershed; the key aspects of critical rainfall include rainfall amount and rainfall duration. Antecedent moisture content and storm pattern affects highly the estimation of critical rainfall. Using hydrological modeling technique with detailed subbasin delineation and manual for design rainstorm-runoff computation,this study first introduced basic concept and analysis methods on critical rainfall for flash flood early warning,and then investigated the responses of flash flood warning critical rainfall to antecedent moisture content and storm pattern. Taking South Branch Watershed of Censhui in Hunan Province as an example,critical rainfall in scenarios of typical antecedent moisture content and storm patterns was estimated at 3 warning stations of interest in this watershed. This research illustrates that both antecedent and storm pattern play important role in the estimation of critical rainfall and enough attention should also be paid to these factors when a decision to be made on whether a warning to be issued or not. 展开更多
