Static restoration mechanism during hot interrupted deformation of Cu-Zn alloy was studied in the temperature range from $550^{\circ}C$ to $750^{\circ}C$ and at a constant strain rate of 0.1/sec. At a given temperature, the hot interrupted deformations were performed with variation of interrupted time $t_i$ form 1 to 50 sec and of interrupted strain ${\varepsilon}_i$ from 0.15 to 0.90. From the analysis of the values of the critical strain of ${\varepsilon}_c$ for tje initiation of dynamic recrystallization and the peak strain of${\varepsilon}_p$, the relationship ${\varepsilon}_c{\fallingdotseq}0.7{\varepsilon}_p$ was obtained. It was clarified that the softening of the interrupted deformation was mainly the static recrystallization and the fractional softening(FS) which was over 30% mostly confirmed this result. The fractional softening of the interrupted time $t_i$ especially and pre-strain. The FS increased with increasing strain rate, interrupted time and pre-strain. The change of microstructures after hot deformation could be predicted by the FS. when the FS was 30~100%, static recrystallization was happened and grain growth was observed at the condition which was $750^{\circ}C$ deformation temperature, 0.45 prestrain and this condition's FS value was over 100%.

The key feature of GMPLS is the provision of network resources and the automatic set-up of a path. And the mechanism of protection and restoration of a path is presented when network component fails. This paper suggests CR-LDP Static Detour Mechanism and Dynamic Detour Mechanism. CR-LDP Detours are a mechanism to set up detour paths automatically at every node to protect working path. Hence suggested mechanism performance is compared with existing mechanisms by computer simulation.

The texts of "Hwangjenaegyeong(黃帝內經)" explains Hakjil(瘧疾) in detail, especially in the "Jahak(刺瘧)" chapter, where bloodletting treatment is applied in many cases. The following paper categorized and organized Hakjil(瘧疾) cases treated by bloodletting methods, then analyzed applicable subjects and appropriate time for the procedure based on the texts. Afterwards, the mechanism for the cessation of Hakjil(瘧疾) seizures was examined. The findings of this research are as follows. 1. In the contents of "Hwangjenaegyeong(黃帝內經)", the appropriate time for acupuncture and bloodletting procedure is when Hakjil(瘧疾) seizures start to present themselves. 2. When a seizure takes place as a symptom of the body getting rid of the Hak(瘧) pathogen, Yanggi(陽氣) rushes to the locus of the pathogen, causing congestion of Gi(氣) and Blood(血) resulting in static blood[瘀血]. Therefore, bloodletting at the time of seizure initiation helps the flow of Gi(氣) and Blood(血), preventing the rush of Yanggi(陽氣). This is a restoration of the balancing function of Eum(陰) and Yang(陽), which indicates that bloodletting not only promotes smooth flow of Gi(氣) and Blood(血), but extends its effects to mental functions that balances Eum(陰) and Yang(陽). 3. Although Hakjil(瘧疾) seizures are presented in terms of Gi(氣) and Blood(血) in symptoms such as chill and fever[寒熱], static blood[瘀血], pain, etc., a fundamental disturbance in mental functions that control cold and heat seems to be present.

Multiprotocol Label Switching (MPLS) has been developed as a key technology to enhance the reliability, manageability and overall quality of service of core If networks with connection-oriented tunnel LSP and traffic engineering such as constraint-based routing, explicit routing, and restoration. In this paper, we propose a control bandwidth borrowing scheme that maximizes the utilization of tunnel LSPs or physical links by an extension to the RSVP-TE label distribution protocol. MPLS-based core switching network and VPN services rely on the establishment of connection-oriented tunneled LSPs that are configured or predefined by network management systems. The mechanism of network management system varies from (i) a relatively static LSP establishment accounting, to (ii) a dynamic QoS routing mechanisms. With the use of hierarchical LSPs, the extra bandwidth that is unused by the trunk (outer) LSPs should be fully allocated to their constituent end-to-end user traffic (inner) LSPs in order to maximize their utilization. In order to find out the unused extra bandwidth in tunnel LSP or physical link and redistribute these resources to constituent LSPs, we expend the functionality of RSVP-TE and the found unused extra bandwidth is redistributed with a weight-based recursive redistribution scheme. By the extended RSVP-TE and proposed recursive redistributed scheme, we could achieve the instantaneous maximized utilization of tunnel LSP or physical link suffering from the potential under-utilization problem and guarantee the end-to-end QoS requirements. With the proposed scheme, network manager can manage more effectively the extra available bandwidth of hierarchical LSPs and maximize the instantaneous utilization of the tunneled LSP resources.
