By the end of 2016, there were 231 million people over the age of 60 in China, accounting for 16.7% of the total population. About 150 million people aged 65 and over make up 10.8 percent of the total population. China is expected to enter the peak period of population aging by 2035. Therefore, the government as a single pension service main body management pattern already can not adapt to our country entered the aging society, mobilize and fostering social organizations to participate in the pension services is to build perfect endowment service system, satisfy people pension service demand model of a kind of indispensable. In view of the development of social organizations has just started in our country, there exist many problems and difficulties, so this article USES the ISM method, for social organizations to participate in research and analyze influence factors of pension services, and then find out the social organization in the process of participation in pension service problems, put forward effective solutions.展开更多

These operations are time-consuming, labor & budget-intensive and error-prone if activated manually. Hence new approaches have to be designed and applied to meet those demands in a cost-effective way, Self-organizing networks (SON), is a promising approach to handle manual tasks with autonomous manners. More specifically the self-directed functions (self-planning, self-deployment, self-configuration, self-optimization and self-healing) are aid to reduce capital expenditure (CAPEX), implementation expenditure (IMPEX) and operational expenditure (OPEX). In this study, first we investigate the aforementioned impact factors of cost combined with self-functions. Then, we analyze the relative cost benefits causing from deploying the SON functions, using the economical method to have more precise results concerning those potential benefits. At last, the result shows that there is a significant difference in expenses and revenues of WSP with and without SON after enabling self-functions in wireless network.展开更多

The trustworthiness of web service is defined as customized multi-dimensional trust metrics and the user preference is embodied in the weight of each trust metric. A service selection method combining AHP (analytic hierarchy process) and PROMETHEE (preference ranking organization method for enrichment evaluations) is proposed. AHP is used to determine the weights of trust metrics according to users' preferences. Hierarchy and pairwise comparison matrices are constructed. The weights of trust metrics are derived from the highest eigenvalue and eigenvector of the matrix. to obtain the final rank of candidate services. The preference functions are defined according to the inherent characteristics of the trust metrics and net outranking flows are calculated. Experimental results show that the proposed method can effectively express users' personalized preferences for trust metrics, and the trustworthiness of service ranking and selection is efficiently improved.展开更多

Different research project outputs (field survey and workshop reports) produced during the implementation of GFCS APA are reviewed to assess the contribution of GFCS APA programme in the establishment and implementation of NAP process in Tanzania. It is found that the implementation of GFCS-APA programme in Tanzania has improved the availability, accessibility, and applicability of climate information to different stakeholders. This has in turn attributed to significant use of climate information in planning and decision making in target sectors: agriculture and food security, disaster risk reduction, energy, health and water resource management. This has increased the adaptation capacity of vulnerable communities from the impacts of climate variability and change. Furthermore, it is evident that the aims and objectives of establishments of NAP process in Tanzania have been addressed through implementation of GFCS APA Programme. Moreover, since the GFCS APA in Tanzania is implemented within its five pillars namely: observation and monitoring, research, modeling and prediction, climate information systems, user interface platform and capacity development. The achievement made in each pillar contributed in enhancement of resilience of vulnerable communities to climate variability and change hence addressing the aims and objectives of NAP process in Tanzania. Therefore, it is recommended that achievements of GFCS APA Programme in Tanzania to be used as a guide to the development and implementations of the NAP process in Tanzania.展开更多

Previously, we defined an intra-organizational workflow specification model, Process LANguage (PLAN). PLAN, with associated tools, allowed a user to describe a graph specification for processes, artifacts, and participants in an organization. PLAN has been successfully implemented in Agentflow to support workflow (Agentflow) applications. PLAN, and most current WfMSs are designed to adopt a centralized architecture so that they can be applied to a single organization. However, in such a structure, participants in Agentflow applications in different organizations cannot serve each other with workflows. In this paper, a service-oriented cooperative workflow model, Cooperative Agentflow Process LANguage (CA-PLAN) is presented. CA-PLAN proposes a workflow component model to model inter-organizational processes. In CA-PLAN, an inter-organizational process is partitioned into several intra-organizational processes. Each workflow system inside an organization is modeled as an Integrated Workflow Component (IWC). Each IWC contains a process service interface, specifying process services provided by an organization, in conjunction with a remote process interface specifying what remote processes are used to refer to remote process services provided by other organizations, and intra-organizational processes. An IWC is a workflow node and participant. An inter-organizational process is made up of connections among these process services and remote processes with respect to different IWCs. In this paper, the related service techniques and supporting tools provided in Agentflow systems are presented.展开更多

Studies and public education focusing on mental health remain low, leading to poor knowledge and awareness of mental health among the population. <strong>Objective:</strong> The overall aim of this study was to provide a systematic description of mental health services in Ghana. <strong>Methods:</strong> A snowball technique was used to select a total of 42 mental health professionals from six hospitals for interviews. A structured questionnaire was used for data collection. <strong>Results:</strong> Major findings of this study include inadequate human and material resources;poor knowledge of mental health among the population;weak coordination between general practitioners and mental health professionals;inadequate mental health services in schools and prisons. Additionally, 54.8% of respondents reported limited mental health educational materials, and most schools (54.8%) lacking trained resident mental health professionals. The main interventions for service delivery are taking over activities of daily living by nurses, problem assessment, and psychological interventions which achieved the same results (69%). A tendency to consult faith-based healers and prayer camps;a lack of mental health research capacity, specifically research focusing on policies;and weakness in the organization and decentralization of mental health services in Ghana are among the common challenges to seeking care. <strong>Conclusion: </strong>Public mental health education on available resources and services is important. Capacity research focusing on dissemination and implementation of mental health policies can serve as the basis for addressing mental health challenges and improving service delivery in Ghana.展开更多
