As a result, the relative study of definite article THE acquisition has been one of the the most significant tasks of second language acquisition all the time. For English majors, the acquisition of definite articles THE runs through the whole process of language learning and application. Learner' s version of foreign language, known as interlanguage, is a kind of language that exists between the mother tongue (Chinese) and the target language (English). Interlanguage is a systematic unit which changes and develops constantly. Since definite article THE has rather complex and frequently altered usage, it is inevitable that there are a throng of misuse and problems for English majors when they are using definite article THE. This paper intends to do a survey focusing on English majors' application situation of definite article THE. Through analyzing the common misuse and mistakes appeared when English majors are using definite article THE, this paper aims to summerize the FAQ (frequently asked questions) and causes of those misuses. At the same time, the 100 experimental subjects of this survey are equally and randomly chosen from freshmen and third year students of foreign languages college, OUC (Ocean University of China). By comparing the experimental results of two different grade English major students, this paper aims to demonstrate the influence of different grades on the mastering of definite articles THE of English majors.展开更多

Results of a survey among primary care physicians/internists have been supplemented by a comparison with the literature. Methods: In the period from October 5-20, 2015, a survey was sent to 414 primary care physicians/internists in four German cities (n = 10 were undeliverable). The response rate was 58% (n = 235). 34 original works on MPH abuse worldwide were found in the literature and are used in the analysis of the present data situation. The literature published before November 9, 2015 is considered in this paper. Results: 14% of the doctors who took part in the survey said that they had been asked for MPH prescriptions without any medical indication. The most frequent reason given for the request (42%) was adult attention deficit/hyperactivity disorder (ADHD) not verified by documents. According to the comparison with the literature, university students had a lifetime prevalence of MPH misuse ranging from 0.8% to 16.6% and school children had a misuse rate of 4.0%. In the civilian US population, the misuse rate was 4.2%. Among patients in possession of a current MPH prescription due to a diagnosis, the lifetime prevalence was 29% and among adolescents with suspected alcohol and/or drug problems 20%. Conclusions: MPH misuse is a major problem which has not been studied sufficiently. MPH misuse not only plays a role in the field of psychiatry, but also in other disciplines. Misuse particularly following a therapeutic prescription should be taken into account.展开更多

The use of such medications carries significant risk, including intestinal dysmotility and potential for addiction. However, the rates of narcotic use and misuse in patients with UC have not been studied extensively. Functional gastrointestinal disorders(FGID) are prevalent in patients with UC, and have been shown to increase the risk of narcotic use and misuse in patients with Crohn's disease. We hypothesized that patients with UC and a concurrent diagnosis of FGID would have increased rates of both opioid use and misuse in our patient cohort.AIM To evaluate the prevalence of chronic opioid use and misuse in UC.METHODS A retrospective chart review of UC patients seen at the University of Virginia Digestive Health Center was performed on all patients evaluated between 2006 and 2011. Patient demographics, medical, surgical, and medication histories were obtained from the electronic medical record. Concomitant diagnosis of FGID was also noted at the time. The electronic prescription monitoring program was accessed to obtain prescription opioid filling histories. Prescription opioid misuse was defined as opioid prescriptions filled from four or more prescribers and four or more different pharmacies in a 12-mo period.RESULTS A total of 497 patients with UC were included. Patients with UC and FGID were more likely to be female, but no other demographic variables were associated with FGID. Of the UC patients who had FGID, a greater proportion were found to be using opioids chronically(36% with FGID vs 9% without FGID, P < 0.0001)and were misusing prescription opioids(12.8% vs 1.3%, P < 0.001). Multivariate logistic regression demonstrated a significant association with FGID and chronic opioid use(OR = 4.50; 95%CI: 1.91-10.59) and opioid misuse(OR = 5.19; 95%CI1.04-25.76). Tobacco use(OR 2.53; 95%CI: 1.06-6.08) and anxiety(OR 3.17; 95%CI:1.08-9.26) were other variables associated with an increased risk of chronic narcotic use.CONCLUSION FGID was associated with a 4.5-fold increase in chronic opioid use and a 5-fold increased risk of opioid misuse in this patient cohort with UC.展开更多

Initiatives for safe prescribing practices for opioid medications include risk assessment for current and future opioid misuse. A clinical screening tool that can be universally applied to all patient populations is currently not available. Our objective was to provide a brief narrative review on opioid misuse from a Canadian perspective as well as a critical appraisal of the available clinical screening tools for detecting aberrant behaviors associated with opioid misuse. The Drug Abuse Screening Test, Addiction Behaviors Checklist, Diagnosis, Intractability, Risk and Efficacy Inventory, Pain Assessment and Documentation Tool, Prescription Drug Use Questionnaire, Prescription Opioid therapy Questionnaire, Screener and Opioid Assessment for Patients with Pain(SOAPP), Revised SOAPP, Pain Medication Questionnaire, Opioid Risk Tool and Current Opioid Misuse Measure were included in the following review. Overall, a wide variability in quality, sensitivity and specificity was observed between screening tools. There is an overall lack of applicability to diverse patient populations as the majority of screening tools have been validated in pain clinic populations only. To conclude, there is a great need for a validated and convenient aberrant behaviors risk assessment tool that can be applied to a diverse patient population in a clinical setting.展开更多

Security requirements rely on the interactions among normal system execution (use cases), attacks (misuse cases), and necessary security strategies (mitigation use cases), but previous approaches only use a high-level of abstraction. We use refinement to uncover details of each case and the relationships among them before integrating them. We identify and model “includes” and “extends” relationships within each refined case type, and use a condition-driven process that maintains these relationships as refinement continues. We then systematically identify and model “threatens” and “mitigates” relationships to integrate the cases at a detailed level.展开更多

Errors made when they are using English verbs are analyzed from the aspect of the similarities and differences between English verbs and Chinese verbs in this thesis. We can conclude that the most obvious cause of the misuse seems to be the interference of the first language (L1), that is, interlingual errors affect the English output of Chinese students. At last, the author calls for more input of the difference between L1 and L2 in L2 teaching and acquisition so that the same mistakes can be avoided.展开更多

A deterministic mathematical model for assessing the impact of daily intravenous drug misuse on the transmission dynamics of HCV is presented and analyzed. A threshold quantity known as the reproductive number has been computed. Stability of the steady states has been investigated. The dynamical analysis reveals that the model has globally asymptotically stable steady states. The impact of daily intravenous drug misuse on the transmission dynamics of HCV has been discussed through the basic reproductive number and numerical simulations.展开更多

Psychoactive drugs are some of the drugs more commonly abused, also, antibiotics and other medications too can be misused. Drug abuse and misuse can lead to serious social, medical and emotional harm to the patients, and antibiotic resistance that makes treatment harder are also likely complications. Method: Patients in both male and female wards of the Orthoepaedics Department of ATBUTH, Bauchi were interviewed using a structured questionnaire and their responses were recorded and data were analyzed using the SPSS version 29. Results: A total of 112 patients were interviewed, 76 males and 36 females. Thirty-two (28.6%) patients had taken various kinds of unprescribed medications while on admission: 9 patients had taken unprescribed tramadol, 4 patients had taken codeine, 6 Ampiclox, 5 flagyl and about 8 patients had taken different kinds of traditional medications while on admission. Among the 32 patients, 23 (72%) are aged less than 30 years, 5 (16%) are aged between 30 and 50 years and 4 (12%) are aged above 50 years. Sixteen (50%) had such medications brought to them by relatives or friends, 10 (30%) were given by other patients on admission, 5 (15%) brought or bought the drugs by themselves while 1 (5%) were given by a non-clinical staff of the hospital. Conclusion: Drug misuse and abuse is a very serious, deleterious practice with destructive consequences in its wake, such consequences as drug dependency with all its antecedent effects, antibiotic resistance and difficulties in controlling/managing infections are but a few. So, it’s very important to both educate patients about these terrible practices and cope with the spread of them in our wards and hospitals.展开更多

While the unprecedented advance in human embryo gene editing research has great potential in next-generation therapeutics, it raises various ethical concerns that need to be addressed before being translated for clinical use. Here, we discuss the current and potential applications of CRISPR/Cas9 technology and its limitations in clinical applications, as well as ethical and legal considerations in the treatment, disease prevention or disability in somatic cells or human embryo via gene editing.展开更多

This results in an increased emergence of resistance to most common bacteria, higher cost of treatment, prolonged hospitalization and adverse drug reactions. Interventions measures have been instituted to avert the problem but it still persists. A systematic review was conducted to determine the effect of different interventions (education, managerial, diagnostic tests, regulatory, economic and multifaceted) on misuse of AB drugs in developing countries. A total of 722 articles were retrieved and 55 were reviewed. About 10.9% of the studies were from Africa, 63.6% from Asia, 9.1% from Latin America, and 16.4% from Southeastern Europe. A total of 52.7% of the studies were from hospital settings, 5.5% from outpatient departments, 21.8% were from public health care facilities, 12.7% from private pharmacies/drug stores, and 7.3% from the communities. Education intervention had 27.3% studies, managerial had 20%, managerial/education had 3.6%, regulatory had 9.1%, education/regulation had 9.1% and diagnostic had 3.6% studies. Multifaceted intervention had 27.3% studies, with 63% improvement in appropriate AB doses prescribed, 2.6% mean number of AB encounter reduction, 23% AB prescription reduction, 18.3% generic AB prescription improvement, 32.1% reduction in AB use, 89% reduction in AB use in acute respiratory infection, 82% in surgery, 62.7% mean reduction in deliveries, 39% in STDs, 36.3% mean reduction in diarrhea, 14.6% mean reduction AB use in malaria, and 6%-11% in the cost of treating bacteria-resistant organisms. Also noted was 6.3% reductions in mean AB encounters after 1 month of intervention, and then increased to 7.7% after 3 months thus lacking sustainability. Multifaceted interventions were effective in reducing irrational AB drug use in the various health facilities and communities as well as reduction in the emergence of resistance to the commonest bacteria in the developing countries though there was lack of sustainability or continuity of rational drug use over the time.展开更多

文摘Objectives: This paper deals with the methylphenidate (MPH) misuse by adults in Germany. Results of a survey among primary care physicians/internists have been supplemented by a comparison with the literature. Methods: In the period from October 5-20, 2015, a survey was sent to 414 primary care physicians/internists in four German cities (n = 10 were undeliverable). The response rate was 58% (n = 235). 34 original works on MPH abuse worldwide were found in the literature and are used in the analysis of the present data situation. The literature published before November 9, 2015 is considered in this paper. Results: 14% of the doctors who took part in the survey said that they had been asked for MPH prescriptions without any medical indication. The most frequent reason given for the request (42%) was adult attention deficit/hyperactivity disorder (ADHD) not verified by documents. According to the comparison with the literature, university students had a lifetime prevalence of MPH misuse ranging from 0.8% to 16.6% and school children had a misuse rate of 4.0%. In the civilian US population, the misuse rate was 4.2%. Among patients in possession of a current MPH prescription due to a diagnosis, the lifetime prevalence was 29% and among adolescents with suspected alcohol and/or drug problems 20%. Conclusions: MPH misuse is a major problem which has not been studied sufficiently. MPH misuse not only plays a role in the field of psychiatry, but also in other disciplines. Misuse particularly following a therapeutic prescription should be taken into account.
文摘BACKGROUND Patients with ulcerative colitis(UC) may be exposed to opioids over their disease duration. The use of such medications carries significant risk, including intestinal dysmotility and potential for addiction. However, the rates of narcotic use and misuse in patients with UC have not been studied extensively. Functional gastrointestinal disorders(FGID) are prevalent in patients with UC, and have been shown to increase the risk of narcotic use and misuse in patients with Crohn's disease. We hypothesized that patients with UC and a concurrent diagnosis of FGID would have increased rates of both opioid use and misuse in our patient cohort.AIM To evaluate the prevalence of chronic opioid use and misuse in UC.METHODS A retrospective chart review of UC patients seen at the University of Virginia Digestive Health Center was performed on all patients evaluated between 2006 and 2011. Patient demographics, medical, surgical, and medication histories were obtained from the electronic medical record. Concomitant diagnosis of FGID was also noted at the time. The electronic prescription monitoring program was accessed to obtain prescription opioid filling histories. Prescription opioid misuse was defined as opioid prescriptions filled from four or more prescribers and four or more different pharmacies in a 12-mo period.RESULTS A total of 497 patients with UC were included. Patients with UC and FGID were more likely to be female, but no other demographic variables were associated with FGID. Of the UC patients who had FGID, a greater proportion were found to be using opioids chronically(36% with FGID vs 9% without FGID, P < 0.0001)and were misusing prescription opioids(12.8% vs 1.3%, P < 0.001). Multivariate logistic regression demonstrated a significant association with FGID and chronic opioid use(OR = 4.50; 95%CI: 1.91-10.59) and opioid misuse(OR = 5.19; 95%CI1.04-25.76). Tobacco use(OR 2.53; 95%CI: 1.06-6.08) and anxiety(OR 3.17; 95%CI:1.08-9.26) were other variables associated with an increased risk of chronic narcotic use.CONCLUSION FGID was associated with a 4.5-fold increase in chronic opioid use and a 5-fold increased risk of opioid misuse in this patient cohort with UC.

文摘We investigate security at the same time as the functional requirements by refining and integrating use, misuse, and mitigation use cases. Security requirements rely on the interactions among normal system execution (use cases), attacks (misuse cases), and necessary security strategies (mitigation use cases), but previous approaches only use a high-level of abstraction. We use refinement to uncover details of each case and the relationships among them before integrating them. We identify and model “includes” and “extends” relationships within each refined case type, and use a condition-driven process that maintains these relationships as refinement continues. We then systematically identify and model “threatens” and “mitigates” relationships to integrate the cases at a detailed level.

文摘Background: The use of drugs for purposes other than those for which they are meant to be used or in excess amounts. Psychoactive drugs are some of the drugs more commonly abused, also, antibiotics and other medications too can be misused. Drug abuse and misuse can lead to serious social, medical and emotional harm to the patients, and antibiotic resistance that makes treatment harder are also likely complications. Method: Patients in both male and female wards of the Orthoepaedics Department of ATBUTH, Bauchi were interviewed using a structured questionnaire and their responses were recorded and data were analyzed using the SPSS version 29. Results: A total of 112 patients were interviewed, 76 males and 36 females. Thirty-two (28.6%) patients had taken various kinds of unprescribed medications while on admission: 9 patients had taken unprescribed tramadol, 4 patients had taken codeine, 6 Ampiclox, 5 flagyl and about 8 patients had taken different kinds of traditional medications while on admission. Among the 32 patients, 23 (72%) are aged less than 30 years, 5 (16%) are aged between 30 and 50 years and 4 (12%) are aged above 50 years. Sixteen (50%) had such medications brought to them by relatives or friends, 10 (30%) were given by other patients on admission, 5 (15%) brought or bought the drugs by themselves while 1 (5%) were given by a non-clinical staff of the hospital. Conclusion: Drug misuse and abuse is a very serious, deleterious practice with destructive consequences in its wake, such consequences as drug dependency with all its antecedent effects, antibiotic resistance and difficulties in controlling/managing infections are but a few. So, it’s very important to both educate patients about these terrible practices and cope with the spread of them in our wards and hospitals.

文摘Model checking based on linear temporal logic reduces the false negative rate of misuse detection.However,linear temporal logic formulae cannot be used to describe concurrent attacks and piecewise attacks.So there is still a high rate of false negatives in detecting these complex attack patterns.To solve this problem,we use interval temporal logic formulae to describe concurrent attacks and piecewise attacks.On this basis,we formalize a novel algorithm for intrusion detection based on model checking interval temporal logic.Compared with the method based on model checking linear temporal logic,the new algorithm can find unknown succinct attacks.The simulation results show that the new method can effectively reduce the false negative rate of concurrent attacks and piecewise attacks.
文摘Patients with chronic pancreatitis often experience severe,unrelenting abdominal pain,which can significantly impact their quality of life.Pain control,therefore,remains central to the overall management of chronic pancreatitis.Most of the strategies aimed at treating the pain of chronic pancreatitis are based on expert opinion and vary from one institution to another,as there are no uniform guidelines to direct a stepwise approach towards achieving this goal.In this editorial,we comment on best practice strategies targeted towards pain control in chronic pancreatitis,specifically highlighting the use of opioid medications in this patient population.We discuss various safe and efficacious prescription monitoring practices in this article.
文摘The recently developed RNA-guided clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated 9 (Cas9) nuclease system has progressed to be an invaluable technology for genome manipulation in somatic cell types and germline model organisms. While the unprecedented advance in human embryo gene editing research has great potential in next-generation therapeutics, it raises various ethical concerns that need to be addressed before being translated for clinical use. Here, we discuss the current and potential applications of CRISPR/Cas9 technology and its limitations in clinical applications, as well as ethical and legal considerations in the treatment, disease prevention or disability in somatic cells or human embryo via gene editing.
文摘Irrational antibiotics/antibacterial (AB) drug use is a global problem, especially in developing countries. This results in an increased emergence of resistance to most common bacteria, higher cost of treatment, prolonged hospitalization and adverse drug reactions. Interventions measures have been instituted to avert the problem but it still persists. A systematic review was conducted to determine the effect of different interventions (education, managerial, diagnostic tests, regulatory, economic and multifaceted) on misuse of AB drugs in developing countries. A total of 722 articles were retrieved and 55 were reviewed. About 10.9% of the studies were from Africa, 63.6% from Asia, 9.1% from Latin America, and 16.4% from Southeastern Europe. A total of 52.7% of the studies were from hospital settings, 5.5% from outpatient departments, 21.8% were from public health care facilities, 12.7% from private pharmacies/drug stores, and 7.3% from the communities. Education intervention had 27.3% studies, managerial had 20%, managerial/education had 3.6%, regulatory had 9.1%, education/regulation had 9.1% and diagnostic had 3.6% studies. Multifaceted intervention had 27.3% studies, with 63% improvement in appropriate AB doses prescribed, 2.6% mean number of AB encounter reduction, 23% AB prescription reduction, 18.3% generic AB prescription improvement, 32.1% reduction in AB use, 89% reduction in AB use in acute respiratory infection, 82% in surgery, 62.7% mean reduction in deliveries, 39% in STDs, 36.3% mean reduction in diarrhea, 14.6% mean reduction AB use in malaria, and 6%-11% in the cost of treating bacteria-resistant organisms. Also noted was 6.3% reductions in mean AB encounters after 1 month of intervention, and then increased to 7.7% after 3 months thus lacking sustainability. Multifaceted interventions were effective in reducing irrational AB drug use in the various health facilities and communities as well as reduction in the emergence of resistance to the commonest bacteria in the developing countries though there was lack of sustainability or continuity of rational drug use over the time.

文摘In recent years,following the development of space commutation,space information has become a critical part in space information network and will play a very significant role in winning future information war.A space information network with characteristics such as complex structure,special communication requirement,long delay,dependence on remote maintenance,and fragile ecological environment contains enormous security risks.Therefore,ensuring space information network safety is important.Intrusion-detection model as an important part of a network security system becomes a hot issue in space network security.We propose an intrusion-detection method that integrates anomaly with misuse,which supports automatic updates from a remote ground,and design a distributed intrusion-detection model of space information network.
文摘It is found in the study that there is a big difference concerning the overall frequency of Do with Hong Kong students using much more DO in their writings than native speakers.Besides,Hong Kong university students tend to overuse the verbal operator DO,which is contrary to Qi Yan's study(2006).At the same time,they also misuse Do;When Do is used as de-lexical verb,Hong Kong students share the same characteristics with the study of Fu zhuqin(2006),that is,they allow more freedom to collocate with more Nouns,some of which are inappropriate collocates in native English.The potential reasons for these problems might be illustrated as overgeneralization,mother-tongue interference,and lack of vocabulary etc.Based on the findings,the paper presents two pedagogical implications about vocabulary teaching and learning:the content of vocabulary teaching should be extended and enriched,and the corpus-based vocabulary teaching methodology should be integrated into class practices.
