Distributed Object Medical Imaging Model

Abstract- Digital medical informatics and images are commonly used in hospitals today,. Because of the interrelatedness of the radiology department and other departments, especially the intensive care unit and emergency department, the transmission and sharing of medical images has become a critical issue. Our research group has developed a Java-based Distributed Object Medical Imaging Model(DOMIM) to facilitate the rapid development and deployment of medical imaging applications in a distributed environment that can be shared and used by related departments and mobile physiciansDOMIM is a unique suite of multimedia telemedicine applications developed for the use by medical related organizations. The applications support realtime patients’ data, image files, audio and video diagnosis annotation exchanges. The DOMIM enables joint collaboration between radiologists and physicians while they are at distant geographical locations. The DOMIM environment consists of heterogeneous, autonomous, and legacy resources. The Common Object Request Broker Architecture (CORBA), Java Database Connectivity (JDBC), and Java language provide the capability to combine the DOMIM resources into an integrated, interoperable, and scalable system. The underneath technology, including IDL ORB, Event Service, IIOP JDBC/ODBC, legacy system wrapping and Java implementation are explored. This paper explores a distributed collaborative CORBA/JDBC based framework that will enhance medical information management requirements and development. It encompasses a new paradigm for the delivery of health services that requires process reengineering, cultural changes, as well as organizational changes

The success factors for government information sharing (GIS) in natural disaster management and risk reduction

The frequency of natural disasters has been increasing for the last 30 years in the world, having caused great damages/losses. Among those damages/losses, about 90 % are concentrated in the Asian region where natural disasters are one of the serious issues not only for humanitarian but also for economic and industrial point of view. These bring about the loss of lives, property, employment and damage to the physical infrastructure and the environment. Disaster management (DM) including risk reduction efforts aim to minimize or avoid the potential losses from hazards, assure prompt and appropriate assistance to victims of disaster, and achieve rapid and effective recovery. While information, knowledge and resources sharing can enhance the process of DM, there is a perceived gap in government collaboration and coordination within the context of natural DM. Identifying potential success factors will be an enabler in managing disasters. The objective of this paper is to present the literature findings on success factors that ensure government information sharing quality in supporting effectively DM. Accordingly the identified factors were classified into major categories, namely political leadership support, inter-agency collaboration, individual agency capacity including ICT, and agency benefits

Preparation and characterization of hydrogels from grafting of vinyl pyrrolidone onto carboxymethyl cellulose

In this work, hydrogels were prepared from carboxymethyl cellulose (CMC) and 1-vinyl-2-pyrrolidone (VP) by Electron Beam irradiation in the presence of N,N’-methylenebisacrylamide (BIS) as a crosslinking agent. The parameters studied include stirring time and percentage of crosslinking agent. Hydrogels were characterized using Fourier Transform Infrared (FTIR) spectroscopy and Scanning Electron Microscopy (SEM). VP and BIS were found be effective as reinforcement materials to improve the properties of CMC. Meanwhile, the optimum conditions were 5% BIS and 3 hours of stirring time. The gel fraction increased when irradiation dose was increased. FTIR confirmed the crosslinking reaction between CMC and VP after the irradiation process by using BIS as the crosslinking agent. TGA thermograms showed changes in the thermal properties of CMC-VP hydrogels in the presence of different amounts of BIS

The sketch nation: psychological evaluation of architectural appreciation through the means of urban sketching towards increasing public awareness of sustainable development

The theme of the research will resolve around the two main subject, the art of urban sketching and architectural narrative through the study of psychology, philosophy and anthropology. The title is suggesting a development of the ‘sketch nation’ as a way to increase architectural appreciation and awareness on sustainable development of the public societies by engaging them with the sketching culture in their community. In this way, they will be more aware of their surrounding & social responsibilities towards a better approach of Sustainable Development Goals (SDG) coined by the United Nation (UN). The research concentrates on how does urban sketching relates to develop the knowledge of architecture in public societies towards increasing awareness of sustainable development. The evaluation is done through analyzing theory of perception in cognitive psychology and cross-referencing it with the ‘urban sketching manifesto’ to understand the process of how an urban sketcher absorbs their surrounding while sketching in an architectural setting as well as understanding how an architectural built informs the end ends user to highlight on the efforts implemented for sustainable development

Visual communication in Queen of Langkasuka (Film) / Mohd Haizra Hashim…[et.al]

In the movie Queen of Langkasuka, there is a correlation between visual communication and the characters portrayed. The strength of the images is transformed into verbal aspects that make the visualization as storyteller. The weight of any film is dependent on the broad aspects of its cinematography. In this film, visual communication is elaborated by focusing on the visual aspects and the close relationship between the characters and the space composition in conveying certain messages. In the field of cinematography, the beauty of a film is relying on how its film making process shapes the characters through the visual space composition without the need to describe other characters. A film shoot requires sensitivity in the internal narrative content so that only symbolic visuals and images would communicate with the audience

Purification and characterization of a novel amylase enzyme from red pitaya (Hylocereuspolyrhizus) peel

An amylase enzyme from red pitaya (Hylocereuspolyrhizus) peel was purified 234.2 folds with 72.1% recovery using ammonium sulphate precipitation, gel filtration and ion exchange chromatography. Gel filtration chromatography and SDS-PAGE revealed that the enzyme is monomeric with a molecular weight of 42.1 kDa. The apparent Kmand Vmaxof the amylase were 2.7 mg/ml and 34.30 u/min/mg of protein, respectively. The enzyme was highly active and stable over a wide pH range from pH 3 to pH 11.0, with optimum activity being observed at pH 5.0. The enzyme was highly selective for soluble starch, amylopectin, glycogen and pulullan. The purified amylase did not require calcium and displayed extreme stability with regard to surfactants and oxidizing agents. EDTA, a powerful chelating agent, did not have any significant effect on the stability of the enzyme. Such characteristics have not been previously reported for this type of enzyme from fruit peel. This enzyme, which possesses unique properties, could be widely used in different types of industries, especially in food and biotechnological applications

A novel aqueous two phase system composed of a thermo-separating polymer and an organic solvent for purification of thermo-acidic amylase enzyme from red pitaya (Hylocereus polyrhizus) peel

The purification of thermo-acidic amylase enzyme from red pitaya (Hylocereus polyrhizus) peel for the first time was investigated using a novel aqueous two-phase system (ATPS) consisting of a thermo-separating copolymer and an organic solvent. The effectiveness of different parameters such as molecular weight of the thermo-separating ethylene oxide-propylene oxide (EOPO) copolymer and type and concentration of organic solvent on the partitioning behavior of amylase was investigated. In addition, the effects of phase components, volume ratio (VR), pH and crude load of purification factor and yield of amylase were evaluated to achieve the optimum partition conditions of the enzyme. In the novel ATPS method, the enzyme was satisfactorily partitioned into the polymer-rich top phase in the system composed of 30% (w/w) EOPO 2500 and 15% (w/w) 2-propanol, at a volume ratio of 1.94 and with a crude load scale of 25% (w/w) at pH 5.0. Recovery and recycling of components was also measured in each successive step of the ATPS process. The enzyme was successfully recovered by the method with a high purification factor of 14.3 and yield of 96.6% and copolymer was also recovered and recycled at a rate above 97%, making the method was more economical than the traditional ATPS method

Relationship between the microstructure and property of Al-0.21wt% Mg-0.41wt% Si alloy

In this study, the relationships between microstructure and property have been investigated for Al­ 0.21wt%Mg-0.41wt%Si alloy. JMatPro calculations was used to predict the phase relationships as a function of temperature. The effects of solution treatment (ST) and artificial ageing (AA) as well as natural ageing at room temperature (NA) were studied. A comparison of the alloy ageing response was made at different ageing temperatures using Vickers hardness test. Tensile test was carried out to evaluate the strength and ductility of the alloy. The microstructures of as received and solution treated alloys were observed by polarized light optical microscopy. The morphology of the precipitates formed was monitored using transmission electron microscopy (TEM). Results indicate that needle-shaped precipitates are responsible for hardening the alloy. The higher density of precipitates in the alloy enhanced the precipitates strengthening. It was found that the tensile strength results for the alloy that aged at room temperature and 185°C followed the hardness graphs trends. The most possible particles observed in the solution treated alloy were suspected to be a or 13-A1FeSi and a-AlMnSi. The results of TEM-EDX analysis were verified by JMatPro calculations
