Observation of the effect of one-to-one education on high-risk cases of diabetic foot

BACKGROUND Diabetes is a common chronic disease,and its global incidence is on the rise.The disease is directly attributed to insufficient insulin efficacy/secretion,and patients are often accompanied by multiple complications.Diabetic foot is one of the most common complications of diabetes.Diabetic feet have ulcers and infections,which can eventually lead to amputation.Basic nursing care,such as lowering blood pressure and preventing foot skin infections in clinical nursing work,has positive significance for the prevention and control of diabetic feet.AIM To explore the positive significance of one-to-one education in high-risk cases of diabetic foot.METHODS This observation included 98 high-risk cases of diabetic foot in our hospital during the period from August 2017 to October 2019,and these patients were randomly divided into the basic nursing group and the one-to-one education group with 49 patients per group.The basic nursing group only received routine basic nursing,while the one-to-one education group gave patients one-to-one education on the basis of basic nursing.After nursing,the self-care ability and compliance behavior of the two groups were evaluated and compared between these two groups.The knowledge mastery of the patient and the satisfaction of nursing were accounted.RESULTS The assessment results of patients(self-care responsibility,self-care skills,selfconcept and self-care knowledge)were significantly higher in the one-to-one education group than in the basic nursing group.The scores of compliance behaviors(foot bathing,shoes and socks selection,sports health care)in the oneto-one education group were significantly higher than those in the basic nursing group.Patients in the one-to-one education group had a significantly higher level of knowledge mastery and satisfaction of nursing than the basic nursing group.CONCLUSION One-to-one education for high-risk cases of diabetic foot is helpful to improve the cognition and self-care ability of patients with diabetic foot,to ensure that patients follow the doctor’s advice of self-care and to improve their nursing satisfaction.

A Fast LDL-factorization Approach for Large Sparse Positive Definite System and Its Application to One-to-one Marketing Optimization Computation

LDL-factorization is an efficient way of solving Ax = b for a large symmetric positive definite sparse matrix A. This paper presents a new method that further improves the efficiency of LDL-factorization. It is based on the theory of elimination trees for the factorization factor. It breaks the computations involved in LDL-factorization down into two stages： 1） the pattern of nonzero entries of the factor is predicted, and 2） the numerical values of the nonzero entries of the factor are computed. The factor is stored using the form of an elimination tree so as to reduce memory usage and avoid unnecessary numerical operations. The calculation results for some typical numerical examples demonstrate that this method provides a significantly higher calculation efficiency for the one-to-one marketing optimization algorithm.

Effectiveness of one-to-one feedback methods of teaching with proper metered-dose inhaler technique and correcting errors in chronic obstructive lung disease patients

Objective:To determine the most common mistakes made during the use of a metered-dose inhaler(MDI),and the effect of the repeated trainings performed with demonstration method by providing one-to-one feedback on these mistakes.Methods:This is a quasi-experimental study with a control group.A total of 100 chronic obstructive pulmonary disease(COPD)patients(50 in the control group and 50 in the experimental group)were included in the research.“Patient Information Form(PIF)”(to determine the descriptive characteristics of patients)through the face-to-face interview method,using“MDI Skill Assessment Form”(MDISAF)(it is composed of 10 skill steps about the use of MDI)through observation method was used.Patients in both the groups were asked to use MDI and their abilities regarding use of MDI were assessed.Then in the intervention group,usage of MDI was explained by a nurse via demonstration and placebo MDI.Trainings were repeated on days 1,3,and 5 as from hospitalization of the patient.In the intervention group,three methods were used in this study:“face-to-face training,”“one-to-one,”and“with feedbacks and repeated.”Routine training regarding use of MDI was given by the nurses in the clinic to patients in the control group.The use of an MDI was assessed using MDISAF before training and after the training on the first,third and fifth days of hospitalization.On the seventh day,the last measurement was performed.Percentage,chi square,and mean were used to assess the data.Results:After repetitive training with one-to-one feedback,several differences between the groups in favor of the experimental group were found in 7 of the 10 skill levels of the MDI.There was a significant difference after“training”between the groups in the third,fourth,fifth,sixth,seventh,eighth and ninth MDI steps in posttest measurement(P<0.05).Evaluating the skills of the groups to use MDI from pretest to posttest,it was determined that while the intervention group made less mistakes in steps in which mistakes were made mostly,the control group continued to make mistakes.Conclusions:Inhaler technique intervention with repeated,face to face,and one-to-one feedback trainings can significantly enhance the MDI techniques in COPD patients.The patients in the intervention group made less mistakes during MDI application and their application skills improved.It may be asser ted that the training provided to the intervention group was effective for using the device correctly,while the training provided in the clinic for the control group was inadequate.

An Analysis of Diplomatic Escort Interpreting from the Perspective of Contextual Adaptation

Verschueren's Theory of Adaptation argues that the process of using language is the result of the language users consciously make continuous linguistic choices and adapt to the contexts, consciously or unconsciously, for language-internal and/or language-external reasons. The contextual adaptation well explains the characteristics of dynamic contextual development in diplomatic escort interpreting. It is helpful for interpreters to understand that the choice-making was constrained by different contexts in diplomatic interpreting. In addition, interpreters should adapt to the various factors of the context thus can make flexible and appropriate choices in delivering target language in order to promote the quality of interpretation and achieve the satisfactory communicative effect.

US“Maximum pressure”From the Perspective of Bottom-Line Thinking-Taking the Persian Gulf Escort Coalition as an Example

This article attempts to take the formation of the Persian Gulf Escort Coalition after the oil tanker attack and detention as the starting point to discuss the bottom-line thinking of the parties involved in and the dilemma of US“maximum pressure”.The“maximum pressure”is the product of zero-sum thinking.In the case of"maximum pressure",the allies may predict the worst outcome out of bottom-line thinking,which will change their support for the US,resulting in not only being unable to isolate their opponents,but also isolating the US itself.And in the case of"maximum pressure",the opponent will also prepare for the worst out of bottom-line thinking,which will easily make the contradictions more intensified and cause unnecessary strong backlash from the opponent.Under the guidance of bottom-line thinking,out of consideration of history or other factors,allies or opponents may make choices that are different from expectations,leading to the risk of strategic-misjudgment.In summary,the formation of the Escort Coalition in the Persian Gulf was an unsuccessful act of"maximum pressure",and the"maximum pressure"strategy that time did not achieve the expected results because of the bottom-line thinking of the allies.

Ethical Problems in MTI Students’Escort Interpreting from the Perspective of Chesterman’s Models on Translation Ethics

The professionalization of translation has been discussed by many scholars in recent years,which has inspired the intense discussion of translation ethics.Drawing upon Chesterman’s models on translation ethics,this paper intends to examine the ethical problems in MTI students’escort interpreting for Vanuatu Sport Technical Assistance Project for the Pacific Mini Games in 2017 and China-ASEAN International Capacity Cooperation Forum in 2016.The data was collected by the methods of participant observation and informal interviews in the process of the two interpreting projects,especially the six-month assistance project.The ethical problems in the escort interpreting and the reasons that caused the problems were analyzed through case study.It is found that the major ethical problems that occurred are related to the ethics of communication,the norm-based ethics,and the ethics of commitment.These ethical problems were mainly related to the student escort interpreters’language proficiency,professional qualities,and intercultural/interpersonal communication competence.Some solutions are suggested based on Chesterman’s models on translation ethics.It is hoped that the research findings can provide some references to the implementation of the similar interpreting programs in the future,and enhance interpreting teaching and training programs.
