  • The purpose of the present study was to investigate the effects of age, sex, cognitive style and reward presentation on delay of gratification. The subjects of this study were 120 children 4, 6 and 8 years of age attending preschool and an elementary school in Pusan. They were identified as impulsive or reflective according to their performance on Kagan's Matching Familiar Figures Test. The levels of reward presentation consisted of the reward which was presented physically and the reward which wasn't presented physically. Length of waiting time was recorded as the measure of maintenance of delay of gratification. The data of this study were analyzed with Two-way ANOVA, Duncan's Multiple Range Test. The major finding were as follows: (1) Delay time increased with age. (2) No sex difference is found in delay time. (3) Reflective children delayed longer than impulsive children in all age groups. (4) The reward which wasn't physically presented produced loner delay time than the reward which was physically presented in all age groups.

  • Background: There is strong evidence that delayed diagnosis of breast cancer is associated with poor survival. Our objectives were to determine the frequency of breast cancer patients with delayed presentation, the reasons of delay and its association with different socio-demographic variables in our North Pakistan setting. Materials and Methods: We interviewed 315 histologically confirmed breast cancer patients. Delay was defined as more than 3 months from appearance of symptoms to consultation with a doctor. Questions were asked from each patient which could reflect their understanding about the disease and which could be the likely reasons for their delayed presentation. Results: 39.0 % (n=123) of patients presented late and out of those, 40.7% wasted time using alternative medicines; 25.2 % did not having enough resources; 17.1 % presented late due to painless lump; 10.6% felt shyness and 6.5% presented late due to other reasons. Higher age, negative family history, < 8 school years of education and low to middle socio-economic status were significantly associated with delayed presentation (p< 0.05). Education and socioeconomic status were two independent variables related to the delayed presentation after adjustment for others (OR of 2.26, 2.29 and 95%CI was 1.25-4.10, 1.06-4.94 respectively). Conclusions: Significant numbers of women with breast cancer in North Pakistan experience presentation delay due to their misconceptions about the disease. Coordinated efforts with public health departments are needed to educate the focused groups and removing the barriers identified in the study. Long term impact will be reduced overall burden of the disease in the region.

  • Purpose: A multicenter, observational, cross-sectional study was conducted to assess factors delaying presentation of breast cancer cases. Materials and Methods: Data were collected from a pair of highly specialized referral centers, both located in the center of the Sudanese capital, Khartoum. For a total of 153 eligible respondents, durations of delay, clinicodemographic factors and reasons of referral were collected from our respondents through self-administered questionnaires. Logistic regression analysis and ANOVA were used to test the relation between periods of delay and different factors. Odd ratios (OR's) and their correspondent Confidence intervals (95% CI's). Delay periods were studied with Andersen's model. Results: The average duration of delay in our study was 11.9 (${\pm}11.2$) months. Only a quarter of our patients presented early within the first 3 months after onset of their symptoms. About 47.7% arrived later during the course of the first year, while it took beyond that for the last 27% to come. A prior diagnosis of BC was the only predictor of early presentation (for 3-12 months OR=9.6 (p<0.00), 95% CI 9.55-9.75; for >12 months OR=9.3 (p<0.00), 95% CI 9.33-9.33). Out of the 12 different reasons for delay given by our respondents, none showed a significant difference between patients presenting early or late. Financial incapacity (17.5%), ignorance about BC (14.3), and misinterpreting symptoms (12.7%) were the top three whys of delay. Conclusions: Our findings support existence of a non-uniform pattern of delay among Sudanese BC patients. Changing currently adopted awareness elevating strategies into much more inclusive approaches is strongly recommended.

  • A synchronized multimedia presentation consists of a collection of objects, with each object having one or more rendering intervals within the presentation timeline. These intervals specify the objects' start times and end times relative to the presentation timeline. In this paper we consider the problem of streaming a multimedia presentation from a server to a client over a bandwith-limited communication network. We suppose that each of the static objects is layered-encoded. For a given maximum delay, we consider the problem of finding the optimal number of quality of the presentation. We devise efficient algorithms for determining an optimal policy for several criteria. We also consider the problem of gradual rendering of objects after their start times.

  • Synchronizations of intra${\cdot}$intermedia for the lecture presentation in distributed multimedia environments are difficult to guarantee accurate temporal relationship between media, due to the asynchronous errors such as the delay or loss of transferred data or the transmission characteristics of each media. The jitter phenomenon occurs when the network delay has the media arrival rate abnormal because the intra-media synchronization reflects the presentation rate. And the cumulative effective of jitters on a per media stream basis results in a skew. This phenomenon cause confusion to contents recognition of learners due to network delay and can not provide effective interaction of sender and receiver in the distance education. Therefore, this paper can be solution to problems due to network delay by maintaining the requirements of temporal relationship between more than one media. And this paper enables to suggest the inter-media synchronization method that is subject to be influenced by presentation rate, and to implement lecture presentation system for distance education.

  • Reperfusion delay in patients with acute myocardial infarction leads to increased morbidity and mortality. We sought to measure the rates of reperfusion delay and to identify factors associated with reperfusion delay after arrival to hospitals. We included 360 patients who had acute myocardial infarction with ST-elevation or left bundle branch block on electrocardiogram and received reperfusion therapy from the three participating academic medical centers from 1997 to 2000. Through retrospective chart review, we collected data about time to reperfusion therapy, patient and hospital factors potentially associated with reperfusion delay. Factors independently associated with reperfusion delay were determined by logistic regression analysis. Median door­to­needle time was 60.0 minutes, and median door­to­balloon time was 102.5 minutes. According to recommendation of the American College of Cardiology/American Heart Association Guidelines, 226 out of 264(85.6%) of thrombolytic patients and 43 out of 96(44.8%) percutaneous transluminal coronary angioplasty(PTCA) patients experienced reperfusion delay. The significant factors associated with delay were type of reperfusion therapy, patient factors including hypertension and delayed symptom onset to presentation(>4 hours), and hospital factors including nocturnal presentation(6pm∼8am), weekend, and an individual hospital. A significant proportion of patients experienced reperfusion delay. The identified predictors of reperfusion delay may help design a hospital system to reduce the delay in reperfusion therapy

  • Delay in seeking treatment for breast cancer is a barrier to the early diagnosis and management of the disease, resulting in a poorer prognosis. We here estimated the prevalence of delayed presentation for breast cancer and identified possible influential sociodemographic factors in a cross-sectional study of 250 patients diagnosed with primary breast cancer at the Radiotherapy and Oncology Clinic in Kuala Lumpur Hospital. Data were collected by face-to-face interview using a structured questionnaire and from medical records. We examined associations between delayed presentation (presenting to a physician more than 3 months after self-discovery of a symptom) and sociodemographic characteristics, practice of breast self examination (BSE), history of benign breast disease, family history of breast cancer and type of symptom, symptom disclosure and advice from others to seek treatment using multiple logistic regression. Time from self-discovery of symptom to presentation ranged from tghe same day to 5 years. Prevalence of delayed presentation was 33.1% (95%CI: 27.4, 39.3). A significantly higher proportion of delayers presented with late stages (stage III/IV) (58.3% vs. 26.9%, p<0.001). Divorced or widowed women (OR: 2.23, 95% CI: 1.11, 4.47) had a higher risk of delayed presentation than married women and women who never performed breast self examination were more likely to delay presentation compared to those who regularly performed BSE (OR: 2.74, 95% CI: 1.33, 5.64). Our findings indicate that delayed presentation for breast cancer symptoms among Malaysian women is high and that marital status and breast self examination play major roles in treatment-seeking for breast cancer symptoms.

  • In the area of speech processing, raw signals used to be presented in 2D format and different kinds of algorithms use the format to solve their problems. However, such kinds of presentation methods have limitations to extract characteristics from the signal, even though the algorithms are quiet good. The basic reason is that not much information can be detected from the 2D signal. Strange attractor in the field of chaos theory provides the 3D presentation method. In the area of the recognition problem, signal construction method is very important because good features can be detected from a good shape of attractors. This paper discusses a new presentation method that can be used to construct strange attractor in a different way. Normal strange attractor uses time-delay idea while the new method uses time-delay and vector average. This method provides us good information to be applied to speaker recognition problem.

  • This paper preposes a various policies and experiment results to select streams in a presentation to be transcoded for mobileterminals after distinguishing the characteristics of streams in the presentation. This applies to the presentation composed of various data streams on a PC server. The rationale of the research is that the stream selection polices for transcoding enhances the speed of presentation in mobile terminals considerably faster than in the case when every stream has to be transcoded. Thus, the thesis suggests a stream selection polices for transcoding based on EPOB (End Point of Over Bandwidth) and aims to lower the requiring bandwidth of the presentation to the network bandwidth as well as to minimize early delay time for the presentation to be played in mobile terminals.
