“Ageing in Place” Policy in Japan: Association Between the Development of an Integrated Community Care System and the Number of Nursing Home Placements Under the Public Long-Term Care Insurance Program Among Municipal Governments

In Japan, an “Integrated Community Care” model has been introduced into the public long-term care insurance (LTCI) system to help persons ageing in place. The aim of the present study was to examine the association between the development of an Integrated Community Care system and the number of nursing home placements under the LTCI program among municipal governments in Japan. Development of the Integrated Community Care system was assessed by a paper questionnaire distributed to each municipality. The annual number of elderly nursing home placements was obtained from published national statistics data over a 10-year period from 2001 to 2010. The sample consisted of 612 municipalities (35.1 % of all municipalities) that responded to the questionnaire. A multilevel linear regression analysis for panel data revealed significantly smaller annual numbers of nursing home placements per 1000 elderly persons among municipalities that had larger number of agencies joining in multiple service networks of the Integrated Community Care system. A significantly greater number of nursing home placements was also observed among municipalities that had a larger elderly population rate, lower annual number of elderly individuals in intermediate care per 1000 elderly persons, and smaller number of elderly individuals in congregate housings per 1000 elderly persons. The national “ageing in place” policy should explore a revised model of the Integrated Community Care system that is applicable for areas with limited resources.

An Improved Optimization Model of Internet Charging Scheme in Multi Service Networks

This paper will analyze new improved charging scheme with base price, quality premium and QoS networks involved. Sain and Herpers [5] already attempted to obtain revenue maximization by creating charging scheme of internet. The plan is attempted to solve multiple service networks scheme as an optimization model to obtain revenue maximization using our improved model based on [2] and [5]. The results show that improved model can be solved optimally using optimization tool to achieve better revenue maximization. DOI: http://dx.doi.org/10.11591/telkomnika.v10i3.623

Threshold impact in CAC for wireless multi-service networks

The optimal adaptive multi-threshold (OpAMT) call admission control (CAC) scheme for multiple service networks has been developed. Analysis reveals that the threshold should be applied to low priority services instead of traditional high priority services. This investigation shows that the adaptive threshold helps to improve the network performance by 43%.

Converged services over MPLS

As network traffic showed explosive growth in the 1990s, layer 2 services became a significant revenue source for providers. Unfortunately, since technology development did not progress in a timely and synchronized manner, many providers now need to manage multiple that are optimized for different services (voice, ATM, IP, etc.). In addition, these may share part of their resources in a layered manner, adding one network on top of the other one (e.g., IP over ATM), which results in overly complicated operation and inefficient use of network resources. Multiprotocol label switching provides a scalable solution for evolving providers' multiple service networks into a unified multiservice network. To make this transition happen, the one critical evolutionary process necessary is to carry the existing layer 1 TDM and layer 2 (ATM, frame relay, and Ethernet) traffic across MPLS core networks. This has been made possible by standardization work in the Internet Engineering Task Force (http://www.ictf.org), and has been successfully deployed by a number of providers around the world. In this article the pre-MPLS methods of network operation for multiple services are addressed, followed by an introduction to MPLS, and the layer 1 and layer 2 over MPLS architecture is provided in detail
