The study aimed to investigate whether heart-type fatty acid binding protein (H-FABP) measurement provides additional diagnostic value to that of conventional cardiac markers in acute myocardial infarction (AMI) within first 6 h after the onset of symptoms. The study included 120 subjects: 60 AMI cases and 60 age and sex matched controls. The cases and controls were further divided into 2 subgroups depending on the time since onset of chest pain as (1) subjects within 3 h and (2) between 3 and 6 h of onset of chest pain. In all the cases and controls, serum H-FABP concentration was measured by Immunoturbidimetric method, serum Troponin I and myoglobin concentrations by Chemiluminescence immunoassay and serum CK-MB concentration by Immuno-inhibition method. The sensitivity, specificity, positive and negative predictive values of H-FABP were significantly greater than CK-MB and myoglobin but were lesser than Troponin I in patients with suspected AMI in both within 3 h and 3–6 h groups. Receiver operating characteristic curves demonstrated greatest diagnostic ability for Troponin I (AUC = 0.99, p < 0.001) followed by H-FABP (AUC = 0.906, p < 0.001) within 3 h and 3–6 h after the onset of chest pain. In conclusion, the diagnostic value of H-FABP is greater than CK-MB and myoglobin but slightly lesser than troponin I for the early diagnosis of AMI within first 6 h of chest pain. H-FABP can be used as an additional diagnostic tool for the early diagnosis of AMI along with troponin I.  相似文献

The main aim of the study was to evaluate trainee teachers working commitment in their teaching practicum. There were seven component teaching practices and eleven demographic factors. The instrument of the study was extracted from various sources to suit the research design based on Units, Treatments, Observing, and Surveying (UTOS) model modification. The reliability index obtained for both research instruments were reasonably good ranging from 0.7030 to 0.9053. A total of 276 trainee teachers who were doing their practical teaching in one of the state in Malaysia (Kelantan). Stratified random sampling was used. They made their self-assessment by using the working commitment instrument. At the same time, their teaching processes were guided through conferences, observations and finally evaluations to get their comparative scores of teaching performance. The data were analyzed by using statistical multiple regression at significant ofp 〈 0.05. As a result, a linear equation of trainee teachers' commitment comprises contribution of work load, work satisfaction, study opportunities, teachers' prospect, marital status, teaching practices, planning and preparation teaching procedure, and religious studies. Furthermore the findings of this study led to some suggestions for future teachers development and become more efficient and adaptive.  相似文献

The Faculty of Electrical Engineering, University Technology Malaysia is currently moving towards a Problem-Based Laboratory implementation rather than the conventional instructional-based laboratory for final year students. The laboratory has commenced session with about 500 students' registration in the 2007/08/1. The Problem-Based Laboratory requires each group of four or five students to solve three given problems in three different laboratories per semester. Each problem has to be solved by conducting the related experiment within four weeks. As they are various evaluation criteria that need to be considered, a web-based evaluation system is proposed in determining the final grade of the students. The evaluation system allows the laboratory coordinators to log in as administrators in order to monitor the evaluation process, which involves both the laboratory technicians and students. The developed web-based evaluation system has proven its capability in working interactively with the users. From the uploading of student's information, group division, marks insertion and total marks calculation for the final grade. It is anticipated that the web-based evaluation system can ensure reliability and security in determining a student's grade in a Problem-Based Laboratory in a shorter time especially when dealing with a large number of students.  相似文献

ObjectivesTo gain consensus among an ethnically and linguistically diverse group of international child protection experts on the structure and content of a new survey tool for retrospective measurement of child abuse, and to determine the performance of the instrument through an international field trial with young adults.MethodsThe questionnaire was developed through focus group discussions with international experts, and then subjected to a Delphi study in two waves to determine the perceived importance and translatability of items. The resultant questionnaire was translated into six languages and field tested in seven countries with convenient samples of young adults aged 18–26 years (N = 842).ResultsChild maltreatment experts from 28 countries provided input to questionnaire development. Satisfactory agreement on draft item inclusion and exclusion and the translatability of items was gained. The tool includes 15 primary questions about potentially abusive physical, sexual and emotional events, with follow-up questions about perpetrator characteristics, frequency of acts and periods in childhood when the recalled abuse occurred. The field test revealed lifetime prevalence per item usually exceeded 10% (11/15 items; range 2.1–49.5%). Internal consistency (Cronbach's alpha) was moderate to high for each of three item sub-sets (between .61 and .82) and the rates of missing data were low (less than 1.5% for 14 of 15 items). The great majority of respondents nominated either peer and/or adult perpetrators (between 82.3% and 98.2% depending upon the item), and among these, child/adolescent peers and non-family adults (including teachers for emotional and physical acts) were nominated often.ConclusionsThe ICAST-R is based on consensus from international experts, translates clearly and has satisfactory properties for adoption as a survey tool to estimate prevalence and describe perpetrators and other contextual aspects of child abuse.Practice implicationsThis tool can be utilized in a broad range of cultures and languages and may contribute to improved research practice. Although the core items are limited to just 15 acts of maltreatment, if these behaviorally specific questions are adopted as key indicators and incorporated into comprehensive local, national or regional surveys, eventually there should be greater comparability in survey estimates.  相似文献

Career indecision particularly among college and undergraduate students is a concern of counselors and psychologists. This concern has led to numerous research studies related to career indecision and factors that influence it, such as family relationships. In this regard, several studies have reported a significant relationship between career indecision and parental attachment. However, little research has been undertaken on the influence of this factor in regard to career indecision for Iranian students. For this purpose, 158 Iranian freshmen and sophomores who had completed the ‘Career Decision Scale’ (Osipow et al., Journal of Vocational Behavior 9:233–243, 1976) and had been identified as career-undecided, completed the ‘Inventory of Parents and Peer Attachment-Revised’ (Armsden & Greenberg, Journal of Youth and Adolescence 16:427–453, 1987). The results revealed that a significant negative relationship was found between career indecision and attachment to mother, whilst the relationship between career indecision and attachment to father was not significant. However, regression analysis showed parental attachment did not significantly predict career indecision of students. Implications and recommendations for further research are discussed.  相似文献

Web‐based learning is becoming prevalent in science learning. Some use specially designed programs, while others use materials available on the Internet. This qualitative case study examined the process of acquisition of integrated science process skills, particularly the skill of controlling variables, in a web‐based learning environment among grade 5 children. Data were gathered primarily from children’s conversations and teacher–student conversations. Analysis of the data revealed that the children acquired the skill in three phases: from the phase of recognition to the phase of familiarization and finally to the phase of automation. Nevertheless, the acquisition of the skill only involved the acquisition of certain subskills of the skill of controlling variables. This progression could be influenced by the web‐based instructional material that provided declarative knowledge, concrete visualization and opportunities for practise.  相似文献

This article aims to describe the differences between research-focused and teaching-focused (non-research) universities in terms of usage of web-based library services, as discovered by way of questionnaires and statistical analyses. It was found that the type of university within the country of Malaysia correlates to significant differences in usage of e-journals and Web-based library services in general. Factors such as library budget allocations, research productivity, and extrinsic motivations for using Web-based library services are surmised to have influenced the usage. The results also suggest that library programs at both types of universities are ineffective in creating awareness of the services. This article discusses several aspects of usage in both types of university and makes several suggestions to remedy identified problems.  相似文献
