Research of Publish and Subscribe Model Based on WS-Notification  [PDF]
Huilian FAN, Guangpu ZEN, Xianli LI
Journal of Software Engineering and Applications (JSEA) , 2009, DOI: 10.4236/jsea.2009.24038
Abstract: WS-Notification bundle of standards, WS-BaseNotification, WS-Topics, and WS-BrokeredNotification, can be used as a general purpose publish/subscribe interface for Service Oriented Architectures. We provide an overview of the WS-Notification specification and describe a modified publish and subscribe model based on WS-Notification. The model is an adaptive policy-driven notification framework that can help enterprises to meet the flexibility and respon-siveness requirements of the enterprise. With the modified publish/subscribe model, information consumers can dy-namically and declaratively create and configure entities on their behalves to manage their distribution requirements.

Abstract: The WS-Notification specification and the WS-Resource Framework (WSRF) provide a scalable publish/ subscribe (pub/sub) messaging model and the ability to model stateful resources using Web services. In this paper, the relationhip between OGSI and the WSRF is introduced first. WSRF can be viewed as a straightforward re factoring of the concepts and interfaces developed in the OGSI version 1.0 specification. WSRF tries to model Stateful Re- sources with Web Services Resource approach to declaring and implementing the association between a Web service and one or more named typed state components. An approach is described for making the properties of a WS-Re- source accessible through its Web service interface and for managing a WS-Resource's lifetime. The discussion on how a pub/sub notification mechanism (WS-Notification) can be built on top of the WS Resource framework is also given. Finally,this paper also presents a summary of WSRF and WS-Notification briefly and a simple discussion on the future research.
Notification Oriented Paradigm (NOP) and Imperative Paradigm: A Comparative Study  [PDF]
Jean M. Sim?o, Cesar A. Tacla, Paulo C. Stadzisz, Roni F. Banaszewski
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.56047
Abstract: This paper presents a new programming paradigm named Notification Oriented Paradigm (NOP) and analyses performance aspects of NOP programs by means of an experiment. NOP provides a new manner to conceive, structure, and execute software, which allows better performance, causal-knowledge organization, and entity decoupling than standard solutions based upon current paradigms. These paradigms are essentially Imperative Paradigm (IP) and Declarative Paradigm (DP). In short, DP solutions are considered easier to use than IP solutions thanks to the concept of high-level programming. However, they are considered slower to execute and lesser flexible to program than IP. Anyway, both paradigms present similar drawbacks like causal-evaluation redundancies and strongly coupled entities, which decrease software performance and processing distribution feasibility. These problems exist due to an orientation to monolithic inference mechanism based upon sequential evaluation by means of searches over passive computational entities. NOP proposes another manner to structure software and make its inferences, which is based upon small, smart, and decoupled collaborative entities whose interaction happen by means of precise notifications. This paper discusses NOP as a paradigm and presents certain comparison of NOP against IP. Actually, performance is evaluated by means of IP and NOP programs with respect to a same application, which allow demonstrating NOP superiority.

Abstract: This paper presents a new programming paradigm named Notification-Oriented Paradigm (NOP) and analyses the performance aspects of NOP programs by means of an experiment. NOP provides a new manner to conceive, structure, and execute software, which would allow causal-knowledge organization and decoupling better than standard solutions based upon current paradigms. These paradigms are essentially Imperative Paradigm (IP) and Declarative Paradigm (DP). In short, DP solutions are considered easier to use than IP solutions due to the concept of high-level programming. However, they are considered slower in execution and lesser flexible in development. Anyway, both paradigms present similar drawbacks such as redundant causal-evaluation and strongly coupled entities, which decrease software performance and processing distribution feasibility. These problems exist due to an orientation to a monolithic inference mechanism based on sequential evaluation searching on passive computational entities. NOP proposes another way to structure software and make its inferences, which is based on small, collaborative, and decoupled computational entities whose interaction happens through precise notifications. This paper presents a quantitative comparison between two equivalent implementations of a sale system, one developed according to the principles of Object-Oriented Paradigm (OOP/IP) in C++ and other developed according to the principles of NOP based on a NOP framework in C++. The results showed that NOP implementation obtained quite equivalent results with respect to OOP implementation. This happened because the NOP framework uses considerable expensive data-structures over C++. Thus, it is necessary a new compiler to NOP in order to actually use its potentiality.

Abstract: This paper presents a new programming paradigm named Notification-Oriented Paradigm (NOP) and analyses the performance aspects of NOP programs by means of an experiment. NOP provides a new manner to conceive, structure, and execute software, which would allow better performance, causal-knowledge organization, and decoupling than standard solutions based upon usual paradigms. These paradigms are essentially Imperative Paradigm (IP) and Declarative Paradigm (DP). In short, DP solutions are considered easier to use than IP solutions due to the concept of high-level programming. However, they are considered slower in execution and less flexible in development. Anyway, both paradigms present similar drawbacks such as redundant causal-evaluation and strongly coupled entities, which decrease the software performance and the processing distribution feasibility. These problems exist due to an orientation to a monolithic inference mechanism based upon sequential evaluation by searching on passive computational entities. NOP proposes another way to structure software and make its inferences, which is based upon small, collaborative, and decoupled computational entities whose interaction happens through precise notifications. In this context, this paper presents a quantitative comparison between two equivalent implementations of a computer game simulator (Pacman simulator), one developed according to the principles of Object-Oriented Paradigm (OOP/IP) in C++ and other developed according to the principles of NOP. The results obtained from the experiments demonstrate, however, a quite lower performance of NOP implementation. This happened because NOP applications are still developed using a framework based on C++. Besides, the paper shows that optimizations in the NOP framework improve NOP program performance, thereby evidencing the necessity of developing a NOP language/compiler.

Abstract: Objectives: The aim of the study was to examine the process of community maternal, neonatal deaths and still births notification within the Bangladesh government health structure using the Maternal and Neonatal Death Review (MNDR) system. The study also explored the feasibility and acceptance of community death notification in the MNDR system. Methods: The study was under-taken in the Thakurgaon district of Bangladesh during 2010. During the study a mix of both qualitative and quantitative information was collected. A review of the documentation process of community death notification was undertaken and focus group discussions (FGDs) with community members, health care providers and managers in a sub-district were conducted, with in-depth interviews (IDIs) with district heath and family planning managers. Quantitative data were collected from community death notifications in the district during January to December 2010. Results: The death notification process was implemented by the government health care system within the Thakurgaon district. Field level health and family planning staff collected maternal and neonatal death information, recorded the death on the notification form and reported back to the Upazila (sub-district of the district) focal point at the Upazila health complex (primary health care centre). Community people were encouraged to share their death information to field level health staff. The health and family planning managers in the district periodically discussed the maternal and neonatal deaths and prepared remedial action plans in high death notified areas. In 2010, 59 maternal deaths, 739 neonatal deaths and 633 still births were reported in Thakurgaon district. District health and family planning departments performed community death notification as part of their routine daily work and integrated these procedures with other field level activities. Conclusion: Community death notification under the MNDR system was found to be achievable and acceptable at the district level using the existing government health system. The simple death notification process used to capture community level maternal, neonatal deaths and still births provides a guide for planning corrective actions for better health outcomes for the community.

Abstract: To assess completeness and timeliness of TB notification, potential TB cases diagnosed by health care facilities in the year 2005-2007 were identified using the reimbursement database of national health insurance (NHI), which has 99% population coverage in Taiwan. Potential TB patients required notification were defined as those who have TB-related ICD-9 codes (010-018) in the NHI reimbursement database in 2005-2007, who were not diagnosed with TB in previous year, and who have been prescribed with 2 or more types of anti-TB drugs. Each potential TB case was matched to the national TB registry maintained at Taiwan Centers for Disease Control (CDC) by using national identity number or, if non-citizen, passport number to determine whether the patients had been notified to local public health authorities and Taiwan CDC. The difference in the number of days between date of anti-tuberculosis treatment and date of notification was calculated to determine the timeliness of TB reporting.Of the 57,405 TB patients who were prescribed with 2 or more anti-tuberculosis drugs, 55,291 (96.3%) were notified to National TB Registry and 2,114 (3.7%) were not. Of the 55,291 notified cases, 45,250 (81.8%) were notified within 7 days of anti-tuberculosis treatment (timely reporting) and 10,041(18.2%) after 7 days (delayed reporting). Factors significantly associated with failure of notification are younger age, previously notified cases, foreigner, those who visited clinics and those who visited health care facilities only once or twice in 6 months.A small proportion of TB cases were not notified and a substantial proportion of notified TB cases had delayed reporting, findings with implication for strengthening surveillance of tuberculosis in Taiwan. Countries where the completeness and timeliness of TB notification has not yet been evaluated should take similar action to strengthen surveillance of TB.Tuberculosis (TB) remains a major public health problem in Taiwan. In 2009, a total of

Abstract: the legally protected occupational pathology consists of work accidents and occupational diseases. diseases are considered to be occupational when there is a relationship of demonstrable causality between exposure to a determinate occupational risk and a specific disease. to facilitate recognition, different organisations (international labour organisation, european community) draw up, update and recommend the use of lists that are voluntarily adopted by member states. in the case of the spanish state, the system of the closed list has been adopted. the current list was published in 1978 and the system of notification and registration currently in use is in need of urgent reform, which has been started. it is frequently difficult to identify the work-related origin of occupational diseases and they are often treated in the public health care system without their relation to work being recognised. knowledge of some basic aspects of the labour legislation by the health workers and the inclusion of a few questions during the anamnesis of patients would make their identification and adequate treatment possible.

Abstract: As the development of web service (WS), applications based on web services (WS), which are convent and platform-independent, have become increasingly popular in recent years. However, how to identify, generate and compose services has become an open issue recently. This paper proposes a method based on program slicing to realize the generation and composition of web services. This paper introduces the method about how to generate a WSDL file and a SOAP message from source codes as well as the theory of function dependence graph (FDG). In addition, this paper gives the way to generate a proxy service for each service, which allows users to easily call a service. The results of experiments show that our generation and composition methods of WS are feasible and flexible.
