  • Nowadays the research of energy saving on the IP networks have been studied the various methods in many research institutes. This paper suggests the energy saving method in IP networks which have the various energy profiles, and analyzes its energy saving characteristics in detail. Especially this paper proposes the energy profile based OSPF routing method which have the selectable weighted value in OSPF metric and energy consumption in IP network. This paper analyzes the energy saving effects of the various situations to minimize the energy consumption using the various weighted value on the proposed scheme. The results show that the energy saving efficiency can get about 67% at in ingress input load ${\rho}=0.5$ by using random energy profiles in IP networks. Although the number of hops is a slight increased due to routing the paths for the minimum energy consumption in the algorithm of this method, the increment hop number is limited the mean 1.4 hops. This paper confirms that the energy profile of core router has the large effects of energy saving than the energy profile of edge router, and the proposed method has the excellent energy saving characteristics in IP networks.

  • Purpose: The purpose of this study is to identify the real condition of urinary incontinence(UI), interstitial cystitis(IC), atrophic viginitis(AV) for elderly women and analyze the cognition of traditional korean medicine(TKM) for them. Methods: We utilized questionnaire from May to June, 2010. Questionnaires were taken from 125 women using senior welfare center and nursing home, aged over 65 up to 92. The data were analyzed by $X^2$-test using SPSS/PC ver 18.0 program. Results: The prevalences of UI, IC and AV symptoms were 50.4%, 40.8%, 56%, respectively. The average I-QoL score for UI was $82.62{\pm}21.16$, and the average ICSI score for IC was $8.16{\pm}2.50$. After adjustment for each of the variables considered in this study, alcohol was associated with UI and age, BMI(body mass index) were associated with IC. Most of respondents have no experience(94.4%) or don't know (79.2%) about TKM for UI, IC and AV. 44 women(37.3%) indicated that they weren't willing to use TKM for UI, IC and AV. Reasons for not taking TKM were because of 'no knowledge of TKM(34.1%)' and 'more accustomed to western treatment(34.1%)'. Conclusion: Although the prevalence of UI, IC, AV for elderly women was high, the actual percentage of treatment for these diseases was low, furthermore, patients were not aware of TKM and had very few experiences of TKM for these diseases. The development and increased promotion about TKM program for elderly women's urogenital diseases is needed.
