To overcome the TV model＇s disadvantageous tendency of uniformly penalizing the image gradient and over smoothing the low-contrast structures, an iterative algorithm based on the l0-norm optimization of the DGT is proposed. In order to rise to the challenges introduced by the l0-norm DGT, the algorithm uses a pseudo-inverse transform of DGT and adapts an iterative hard thresholding （IHT） algorithm, whose convergence and effective efficiency have been theoretically proven. The simulation demonstrates our conclusions and indicates that the algorithm proposed in this paper can obviously improve the reconstruction quality.展开更多

They care for their sick relatives at home and in hospital. Some views of family members indicate that they get satisfaction from participating in nursing care of their sick relative. The aim of this study was to describe the views of family members about nursing care of psychiatric patients admitted at a mental hospital in Malawi. A qualitative study design was used and data were collected from ten participants through in-depth interviews. Ethical approval was granted by relevant authorities. Data were analysed using Colaizzi method. The findings fell into the following four themes that emerged: family participation in nursing care;nurses’ skills and experience in caring;respect for psychiatric patients and interactions and information sharing. This study offers valuable information about the views of families regarding nursing care of psychiatric patients. They are involved in the care of their sick relatives although there is lack of effective cooperation between them and nurses. The lack of collaboration made families receive inadequate information about their sick relative. Therefore, it is imperative that nurses are competent in implementing family involvement in nursing care.展开更多

She is called the"human bridge"for the communication between China and the world outside. She won the Nobel Prize for her rich and genuine description of Chinese peasant life and masterpiece of biography. Being a woman writer, she expressed her great concern to women's life, which could be seen from her famous works. Owing to the special experience in bilingual culture and the assertion of the equality of any cultures in the world, she was a woman with double cultural view: both of Western and Chinese, which must have decided the formation of her feminist views with the Western and Chinese culture basis. In this thesis, her unique feminist views will be illustrated in detail.展开更多

The method for generati ng 3D conic edges from 2D projection conic curves is emphasized especially, whic h is the pivotal work for reconstructing curvilinear objects from three orthogra phic views. In order to generate 3D conic edges, a five-point method is firstly utilized to obtain the algebraic representations of all 2D-projection curves i n each view, and then all algebraic forms are converted to the corresponding geo metric forms analytically. Thus the locus of a 3D conic edge can be derived from the geometric forms of the relevant conic curves in three views. Finally, the w ireframe model is created after eliminating all redundant elements generated in previous reconstruction process. The approach extends the range of objects to be reconstructed and imposes no restriction on the axis of the quadric surface.展开更多

The progress in the establishment of GP OOHs services is considered by the Health Service Executive (HSE) to be a highly significant quality initiative for patient care, and the health service as a whole. Outside of normal GP surgery hours, parents of children can call a dedicated telephone number, to have their urgent health concerns assessed and to be advised about the appropriate level of care. Experienced nurses, who are often based in a GP OOHs centre, assess the call over the telephone and provide advice to the callers. The spur for conducting this study arose from my personal and professional experience which, I believe, underscores the need for exploring and understanding parents’ views of GP OOHs services, in order to bring about change in nurses’ practice of delivering advice over the telephone. The overall aim of the study is to explore and understand the views of parents of children, aged two years and under, following telephone advice received from nurses in the context of a GP out-of-hours service. A qualitative, exploratory, and descriptive design was used to examine the views and experiences of parents of children aged two years and under, who used a GP out-of-hours service provider in Ireland. Nine parents who had received phone advice from a nurse were purposively sampled to take part in the study. Data were collected using semi-structured interviews by telephone. Data were transcribed and analysed thematically. Themes included parents’ perceptions of illness in children with the need to be heard, parents’ views about accessibility to GP OOHs, parents’ expectations that the service would offer guidance and reassurance, parents’ satisfaction with the nurse’s advice, and parents’ experiences of hospital emergency departments (EDs). Suggestions for improving the GP OOHs service were made across these themes. The suggestions include: higher staffing levels, wanting a quicker call back, preference for face-to-face assessment over telephone advice and a preference for a children’s area in the GP OOHs. The study revealed that parents are satisfied with the GP OOHs service and the parental decision-making model has the potential to provide an opportunity to continue the progress of the establishment of GP OOHs services in Ireland.展开更多

We searched for the same term in three different languages, i.e. “Μακεδονíα”, “Macedonia” and “Македонска - Македониjа”, since we are primarily interested in views from Greece and FYROM without excluding views from other regions. We use methods from Social Network Analysis (SNA) in order to create networks of users, calculate some main network metrics, measure user importance and investigate the presence of possible fragmentations—communities among them. We furthermore proceed to a form of content analysis, using pairs of words within tweets, in order to obtain main ideas, trends and public views that circulated over the network.展开更多

This is the reason why a lot of research has been conducted in the literature over the last two decades on their design, refreshment and optimization. The manipulation of hypercubes (cubes) of data is a frequently used operation in the design of multidimensional data warehouses, due to their better adaptation to OLAP (On-Line Analytical Processing). However, the updating of these hypercubes is a very complicated process due mainly to the mass and complexity of the data presented. The purpose of this paper is to present the state of the art of works based on multidimensional modeling using the hypercube as a unit of presentation of data stores. It starts with the base of this process which is the choice of the views (cubes) forming our data warehouse base. The objective of this work is to describe the state of the art of research works dealing with the selection of materialized views in decision support systems.展开更多
