Efficient recovery assistance for individual households is one of the inevitable issues in management after a disaster. Discussion on how the assistance should be provided to them, however, has been put aside whereas amount or contents of it have been disputed every time a disaster happens. Public support system in a time of disaster in Japan is very complicated because many laws are related to recovery support and each law covers just a part of total recovery needs of affected household. It is difficult to see whole picture of the system for affected households. Therefore, households must have many interactions with various sections in charge of particular assistance service to know the contents of each assistance and requirements to receive it to decide combination of supports they use. It is crucial for efficient recovery assistance operation to manage those customer relations since considerable part of troubles in individual recovery came from failure in each interactions caused by lack of common understanding on each recovery process between them. In this paper, I want to introduce how support system in Japan is fragmented, a case of Anamizu town which adopted a customer-oriented framework of information management system for their assistance operation after Mar. 2007 Noto peninsula earthquake and what was learned from the case.

During the past 25 years, in the context of probabilistic safety assessment, efforts have been directed towards establishment of comprehensive pipe failure event databases as a foundation for exploratory research to better understand how to effectively organize a piping reliability analysis task. The focused pipe failure database development efforts have progressed well with the development of piping reliability analysis frameworks that utilize the full body of service experience data, fracture mechanics analysis insights, expert elicitation results that are rolled into an integrated and risk-informed approach to the estimation of piping reliability parameters with full recognition of the embedded uncertainties. The discussion in this paper builds on a major collection of operating experience data (more than 11,000 pipe failure records) and the associated lessons learned from data analysis and data applications spanning three decades. The piping reliability analysis lessons learned have been obtained from the derivation of pipe leak and rupture frequencies for corrosion resistant piping in a raw water environment, loss-of-coolant-accident frequencies given degradation mitigation, high-energy pipe break analysis, moderate-energy pipe break analysis, and numerous plant-specific applications of a statistical piping reliability model framework. Conclusions are presented regarding the feasibility of determining and incorporating aging effects into probabilistic safety assessment models.

This study examined the regulation status on wastewater treatment in agro-food processing and a case study on effluent treatment m ethods was carried out to evaluate any change after the mitigation of regulation. First, in order to clarify the area of investigation, the definition of small-scale agro-processing facilities was reviewed through literature survey and local government ordinance. The current law were separately analyzed into four areas; effluent treatment facilities, development of agro-processing industries, land use and food processes equipment. The exclusion clauses on wastewater discharging facility in the enforcement regulation were defined in detail, which can be served in practice. Site survey, after the questionnaire survey of the person in charge of the local unit, was carried out. As the result, this survey confirmed the positive effects of the deregulation on promoting sewer system service in rural areas, introducing the new processing construction and so on. In addition, it was found that some matters to be considered to determine whether to introduce wastewater treatment plan for public food processing facilities.

Open-cross-section composite beam (OCB) tends to suffer vortex-induced vibration (VIV) due to its bluff aerodynamic shape. A cable-stayed bridge equipped with typical OCB is taken as an example in this paper to conduct sectional model wind tunnel test. Vortex-induced vibration is observed and maximum vibration amplitudes are obtained. CFD approach is employed to calculate the flow field around original cross sections in service stage and construction stage, as well as sections added with three different countermeasures: splitters, slabs and wind fairings. Results show that flow separate on the upstream edge and cause vortex shedding on original section. Splitters can only smooth the flow field on the upper surface, while slabs cannot smooth flow field on the upper or lower surface too much. Thus, splitters or slabs cannot serve as valid aerodynamic means. Wind tunnel test results show that VIV can only be mitigated when wind fairings are mounted, by which the flow field above and below the bridge deck are accelerated simultaneously.

The rapidly aging trend of Korea is a major factor that threatens the sustainability of the long-term care insurance system. Therefore, looking at how Japan and Germany mitigated the financial burden when they managed similar long-term care insurance systems will provide important implications for improving the Korean system in the future. The study was conducted using the literature review method, and the "country" was set as a unit for the case analysis. The three countries selected are Korea, Japan, and Germany. Recently in Korea, the insurance premium rates of all subjects have been rapidly rising, which can exacerbate the issue of intergenerational equity. On the other hand, Japan has responded to the aggravating finances for long-term care insurance due to aging by raising coinsurance for selected groups like the wealthy elderly. Germany is selectively raising the insurance premium rates by additionally increasing the premium rate for childless recipients. A more preventive and quality-oriented care service plan can be promoted by referring to the recent changes in Japan and Germany. In addition, a more effective and selective increase in payment burden in Japan and Germany could be considered in response to a recent equity issue in Korea.

The effective management of damage in tunnels is crucial for ensuring their safety, longevity, and operational efficiency. In this paper, we propose an educational management model tailored specifically for addressing damage in tunnels, utilizing numerical solution techniques. By leveraging advanced computational methods, we aim to develop a comprehensive understanding of the factors contributing to tunnel damage and to establish proactive measures for mitigation and repair. The proposed model integrates principles of tunnel engineering, structural mechanics, and numerical analysis to facilitate a systematic approach to damage assessment, diagnosis, and management. Through the application of numerical solution techniques, such as finite element analysis, we demonstrate the efficacy of the proposed model in simulating various damage scenarios and predicting their impact on tunnel performance. Additionally, the educational component of the model provides valuable insights and training opportunities for tunnel management personnel, empowering them to make informed decisions and implement effective strategies for ensuring the structural integrity and safety of tunnel infrastructure. Overall, the proposed educational management model represents a significant advancement in tunnel management practices, offering a proactive and knowledge-driven approach to addressing damage and enhancing the resilience of tunnel systems.
