Although the concept of family functioning has gained recent popularity, the terms "family functioning" and "family resilience" are sometimes confused and used interchangeably. The aim of this concept analysis was to clarify what is meant by family functioning in the context of diabetes self-management by assessing specific attributes, antecedents, and consequences. A concept analysis model by Walker and Avant was applied. The identified attributes of family functioning in a diabetes self-management context included problem-solving, communication, roles, affective responsiveness, affective involvement, and behavioral control. Antecedents included family structure, socioeconomic status, family functioning relationships, family stage, and life events. Consequences included family satisfaction, family cohesion, and family relationships. This analysis provided a deeper understanding of a family functioning concept within a diabetes self-management context. It is recommended that health care providers should be aware of antecedent factors that could inhibit outcome improvement. Further research is needed to explain family functioning attributes in relation to antecedents and potential consequences. 展开更多

Basketball, as against the competition activities for colleges and universities is very important, one can improve the athletes’ body function, on the other hand can cultivate the team cooperation consciousness and competitive consciousness of athletes. As the basis of basketball, good physical ' tness can to a certain extent, improve the athlete basketball skills and avoid injury, with abundant physical ' tness for basketball game winning advantage. So we must fully implement the function training concept, through a variety of ways to strengthen the basketball ' tness training of athletes, enhance physical ability quality. 展开更多

This paper makes a case study on lines from Disney animation picture Mulan in the light of functional concept of translation. And it draws a conclusion that in the process of film translation, the translator is allowed to make some adaptations to make the translated version more appropriate in the original context, and that the translator is supposed to have both "semantic awareness" and "functional awareness", to achieve the equivalence between the SL text and TL text functionally. 展开更多

Bariatric and metabolic surgeries have gained extensive popularity and trust due to their documented efficacy and safety in managing not only obesity but also associated comorbidities such as diabetes mellitus, hypertension, dyslipidemia, sleep apnea, and joint pain. Traditionally, bariatric surgeries have been categorized into hypoabsorptive, restrictive, or hybrid approaches. However, these classifications inadequately reflect the complex anatomical and physiological alterations associated with modern surgical methodologies. This paper explores the evolution of metabolic surgeries, emphasizing the integration of physiological concepts into classic procedures to provide more tailored and effective treatment options for obesity and its comorbidities. Finally, the proposal for a new classification based on current metabolic concepts will facilitate communication among patients, doctors, and healthcare professionals. Additionally, it will enable a more didactic and standardized approach to data collection for conducting studies and publications. 展开更多

Main goal of this paper is to discuss specific problem which is occurring during the creation of modem complex soRware systems, particularly at the design stage. Many of modem architectural styles are promoting building composite software systems compounded with reusable and flexible units. Because of high speed of contemporary software system evolution which is related to initial process changes, it is very significant to have ability to do related refactoring tasks. Sometimes, when structure if software system is monolithic, modification process takes a long time and in worse cases it is impossible. On the other hand flexible composite systems are easy to govern. Our work is related to complex process decomposition into small simple sub-processes at the architectural level of designing stage. 展开更多

Translation is a trans-cultural communication activity which related to two languages. The main goal of translation is,no doubt, to establish a particular type of correspondence between the source text and the target text. The nature of the correspondence has been referred to"faithfulness"or"fidelity", or more predominantly, the notion of"equivalence".This issue attempts to analyze the brief introduction of the Da Yan Pagoda, which is a famous scene in Xian from the point of functional translation equivalence's view. 展开更多

The air traffic management system(ATM)has the task of ensuring safe,orderly and expeditious flow of air traffic.The ATM system architecture is very much dependent on the concept of operations(ConOps).Over the years the evolution in ConOps has resulted in changes in the ATM′s physical architecture,improving its physical infrastructure,increasing the levels of automation and making operational changes to improve air traffic flow,to cope with increasing demand for air travel.However,what is less clear is the impact of such changes in ConOps on the ATM′s functional architecture.This is vital for ensuring optimality in the implementation of the physical architecture components to support the ATM functions.This paper reviews the changes in the ConOps over the years,proposes a temporally invariant ATM functional model,and discusses some of the main key technologies expected to make significant improvements to the ATM system. 展开更多
