This study aims to provide basic understanding for evaluating the quantitative and qualitative progress of national protected areas, through the theoretical review of Aichi Biodiversity Target 11 in order to comply with recommendations of international community and to conserve biodiversity. As a result of the study, Aichi Biodiversity Target 11 sets out the specific contents that the Parties should achieve for protected areas by identifying them as temporal and spatial goals. The temporal goal, the time schedule for achieving the goal, is 2020, and the spatial goal is divided into quantitative expansion goals and qualitative improvement goals. The quantitative expansion goals present the target coverage of protected areas separately terrestrial and marine. The qualitative improvement goals include the target areas for conservation and five conservation considerations. The conservation targets focus on the important areas with regard to biodiversity and ecosystem services. The five conservation considerations mean effective management, equitable management, ecological representativeness, connectivity, and integration into the landscape and seascape for protected areas. Finally, it suggests that two tracks of protected areas and other effective area-based conservation measures(OECMs) should be used as conservation measures to build an integrated system. The results of this study can be applied to quantitative and qualitative evaluation methods for protected areas and it can contribute to achieve quantitative expansion goals and qualitative improvement goals for them.

The Environmental Conservation Value Assessment Map (ECVAM) is a five grade assessment map created with nationally integrated environmental information and environmental values. The map is made through the evaluation of 67 items, including greenbelt area and bio-diversity. The ECVAM assesses the stability of the community using forest maps. However, the existing assessment method is problematic because the assessment grades are evaluated using higher than practical values; in part because it uses even-valued overlay and minimal indicator methods. This study was performed in order to suggest an integrated assessment method that could complement the stability evaluation based on existing methods. Accordingly, this study added forest type information, including whether the forest was natural or artificial, to the overlay method using forest diameter maps and forest density maps. As a result, the proposed ECVAM indicated a drastic grade change. After applying the method in South Korea, Grade I areas decreased 12.1%, from 52.6% to 40.6%, Grade II areas increased 11.9%, from 17.4% to 29.2%, and Grade III areas increased 0.2%, from 17.1% to 17.4%, respectively. From the results of the field survey, we found differences between natural forest and planted forest with regard to the number of mortality, species of shrubs, and vine cover. This means that natural forests are more stable than planted forests. This study suggests an improved assessment methodology to complement the existing EVCAM method. The results are expected to be used in environmental evaluations and forest conservation value assessments in ecology and environmental fields.

This study was carried out on scientific conservation treatment based on material characteristics, provenance interpretation, and deterioration diagnosis for seven-storied Jungwon Tappyeongri stone pagoda in Chungju. As a result, main rock of the pagoda is biotite granite with magnetite-series (average $5.86{\times}10^{-3}$ SI unit), containing partly basic xenolith, pegmatite veinlet and feldspar phenocryst. As a result of the provenance presumption of the host rock, a rock around the Songgang stream was identified the same origin. Therefore the rock is appropriate for materials of the pagoda restoration. The deterioration assessment suggested that the pagoda was seriously exfoliated (2.7 to 5.5%), discolored (39.8 to 58.9), and contaminated with repair materials (3.5 to 9.4%), and bioorganisms (19.3 to 24.4%). Accordingly, conservation treatment was carried out based on preliminary investigation for stable conservation of the pagoda. Overall processes were sequentially proceeded by restoration of the replacement stone, cleaning, joining and consolidation. This study sets up an integrated conservation system from preliminary investigation to conservation treatment of the pagoda. Also, the study will contribute for establishing the future-oriented customized conservation treatment.

Purpose and Method: Despite benefits of building energy simulations, practitioners seem to be reluctant to use simulations for design decision making. By means of survey and interviews, this study aims to investigate domestic hindrance against increasing simulation usability, and to collect user requirement to enhance technical functionality of the simulation. Also this study compares the Information Sharing Workflow by Stantec and general domestic design process in order to identify a direction of the Integrated Design Process. Result: Finally this study wraps up with suggestions of how simulation functionality and use protocol should be in order to satisfy user requirement and also to gather more users.

This study was performed to develop an information processing system for the sound conservation of soil and groundwater resources. The system contains the geographic information system, and the numerical model of groundwater flow and contamination. Numerical models (MODFLOW,MOC3D) and GIS (ArcView) were integrated for the construction of an integrated management system of subsurface environment. The developed system was applied to the management of three mineral water companies located in clean mountain area. The impact of pumping over the overall catchment basin was modeled using the developed system for the decision of future management criteria.

Railway transport of goods and passengers is effective in terms of energy conservation and travel time savings. Safety and ride quality have become important issues as train speeds have increased. Due to increased speeds, minor damage to railway structures and abnormal interactions between trains and structures have given rise to increasingly serious accidents. Therefore, structural health and operational conditions must be monitored continuously in all service environments. Currently, various health and operation management systems are being developed and these are reducing both maintenance frequency and costs associated with disassembly. In this review, major damage and malfunctions and their locations are first analyzed based on numerous references. Then advanced train health and operation management technologies are classified into wayside detection methods and advanced integrated sensor methods and their operating principle and functions are reviewed and analyzed.

The North Korean laws on natural environments, land and infrastructure were comprehensively analyzed in order to help establish the legal system to solve problems of ecosystem and land management in North Korea. The citizen's environmental rights in North Korean Constitutional Law emphasize the aspect of conservation of the natural environments. The laws on the managements of natural environments and land are relatively integrated in North Korea. In the management of natural environments, ecosystem conservation is centered on designation of natural protected areas. Priority for infrastructure construction is emphasized in land management. The economic and technical support is needed to build advanced legal systems for the conservation of natural environments and ecological land management and to improve their performance of law enforcement.

In this paper, a general Weighted Essentially Non-Oscillatory (WENO) interpolation is proposed and applied to a semi-Lagrangian method. The proposed method is based on the conservation law, and characteristic curves are used to complete the semi-Lagrangian method. Therefore, the proposed method satisfies conservation of mass and is free of the CFL condition which is a necessary condition for convergence. Using a several standard examples, the proposed method is compared with the third order Strong Stability Preserving (SSP) Runge-Kutta method to verify the high-order accuracy.
