  • With HTTP/1.0, a single request means a single HTTP connection so that the granular unit of dispatching is the same as real load. But with persistent HTTP connection, multiple requests may arrive on a single TCP connection. Therefore, a scheme that dispatches load at the granularity of individual requests constrains the feasible dispatching policies In this paper we propose a new connection dispatching polity for supporting HTTP/1.1 persistent connections in cluster-based Web servers. When the request of a base html file arrives, the dispatcher gets the subsequent load arriving on that connection using the embedded objects information. After the dispatcher stores the load information in Load Table, the dispatcher employs the connection aging strategy on live persistent connections on the passage of time. The results of simulation show about $1.7\%\~16.8\%$ improved average response time compared to existing WLC algorithm.

  • At atmosphere photoluminescence(PL) of porous silicon(PSi) decreases and peak wave number of PL is shifted to blue region. When PS is used light detector, the ageing effects are negative phenomena. For controling ageing effects, this paper uses Polymers.

  • An initial starting voltage, ignition time, glow current and blink of the flow starter are changed rapidly in initial using. therefore an ageing is required to stabilize the initial characteristics. According to the experiments, it is proved that the ageing time for the starting voltage and glow current takes 3 minutes and 5 minutes for ignition time and blink.

  • The purpose of this study was to establish planning criteria and development of type for the senior citizen who lives alone in home for the elderly at rural and fishing villages. In order to take most suitable co-housing, this analysis is progressed various building types based on aging in place and aging in health; self care, nono care, service care and community care. This paper is to suggest collective housing with 10 types in large scale and extracted 19 types in detail scale. The basis of classification are location condition; aging in place, building condition, health care condition; aging in health and possession & operation condition. In viewpoint of dwelling welfare 'Home for the Elderly' is to concerned with systematic methodology and architectural typology for senior citizen who lives alone in the rural and fishing village.

  • This study attempts to provide implications for developing more efficient and effective community-based support system with AIP perspective for the elderly in Korea. The main purpose of this study is to analyze Japan's community-based integrated care system that respond to the concept of aging in place (AIP) and its cases. In Japan, they have offered Community-Based Service since 2005, and the advanced system which include integrated support categories and consolidated community/local resources will started in 2015 by The revision of Long-term Care Insurance policy, 2012. The result of policy analysis and case studies are as follows: 1) The suggestion for ideal support system model promoted a relationship of multiple agents include private sectors even resident and senior and specified responsibility sharing, 2) the system proposed Not only health and medical care support, living care and residence are also addressed as a comprehensive support. and 3) the amount of available community resource is different by each local government, but the effort to get the understanding of community residents and to connect with a potential community resource is also essential aspect to set effective community-based support system.

  • This paper discusses the physical properties of permeable high quality concrete using blast furnace slag or steel slag as a part of aggregate. In the case of steel slag, aging treatment was adopted to prevent the volume expansion. With high range water reducing agent, the concrete using slag aggregate showed compressive strength up to 24MPa at the age of 28 days and the water permeability of the concrete was over the level of 0.1 m/s in this experiment. Also, there was no expansion problem in the concrete substituted with aged slag as a part of aggregate.

  • 이동 환경에서의 서비스가 대중화 되면서 문제가 되고 있는 것이 바로 이동 호스트의 전력 제어 문제이다. 이동 호스트는 충분한 전력을 얻기 힘들기 때문에 데이터 전송을 받지 않는 경우에는 최소한의 정보만을 교환하는 상태로의 전의가 필수적이다. 현재 IETF의 Seamoby Working Group에서 논의되고 있는 IP 페이징 프로토콜의 경우에는 요구사항과 논리적인 구조만이 정의되어 있다. 현재 정의되어 있는 구조의 문제점은 유휴 (formant) 모드에 있는 이동 호스트에 데이터를 전송하기 위해서는 Dormant Monitoring Agent(DMA)로 전송된 데이터에 대하여 버퍼링이 수행되어야만 한다. 버퍼링의 목적은 이동 호스트의 유휴 모드에서 활성 (active) 모드로 전의 되는 시간 동안의 데이터의 손실을 방지하기 위함이다. 따라서, 하나의 DMA해서 관리해야 하는 이동 호스트가 많은 경우에는 대회의 양이 문제가 된다. 즉, 확장성 문제점이 존재하게 된다. 본 논문은 이러한 문제점을 줄이기 위하여 Domain Name Server(DNS)를 이용한 IP 페이징 제공 방안을 제안한다. 본 메커니즘은 송신자가 DNS에 호스트의 IP주소를 얻고자 하는 경우 IP 페이징 프로토콜을 먼저 이동 호스트의 페이징 에이전트에 전송함으로써 미리 이동 호스트를 활성 모드로 변경하게 함으로써 이전 메커니즘에서 적용되어야 하는 버퍼의 크기를 줄일 수 있는 메커니즘이다.
