This paper is to investigate the influence of driving patterns of slow and high speed vehicles on the performance of continuously regenerating diesel particulate filter(DPF) system matched with operating conditions in field application. The DPF performance test for field application was carried out for two identical DPFs installed to slow and high speed vehicles. A slow speed vehicle was selected among local buses which have driving patterns to repeat running and stop frequently, while a high speed vehicle was prepared to have long route of high speed over 60km/h like inter-city buses. In this test, the regeneration performance on the DPF of slow speed vehicle deteriorated because of high soot load index(SLI) in spite of same balance point temperature(BPT) distribution for high speed vehicle. The DPF of slow speed vehicle melted in the end because the rapid increase of back pressure caused high temperature over $1200^{\circ}C$ in the ceramic wall of DPF. The PM components like ash collected to the filter in the DPF were analyzed in order to investigate the cause of the defect and provide an operation performance of DPF system. In the result of the analysis, high levels of lubrication oil ash(Ca, Mg, P, Zn) were detected.

Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade $plant{\acute{e}}e$ and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

Being the origin of Shanghai City, the Old Town presents a high-density spatial texture, a characteristic of local living conditions in the Shanghai context. However, the Old Town is faced with competing interests: the preservation of historic urban features and the improvement of contemporary living conditions. In view of its high density and poor living conditions, this paper focuses on two types of blocks for urban design research, and proposes two spatial regeneration strategies, as "overlapping lilong" and "texture continuity". It is expected to inherit the regional characteristics of urban space, improve the plot ratio and supplement the mix of functions, through the translation of the traditional lilong typology and the reproduction of historical streets and alleys, so as to provide operable spatial strategies and design methods for the organic renewal of Old Town and other historic districts.

Accoring to the worldwide interest to control CO$_2$ which contributes to global warming 50%, new techniques to reduce CO$_2$ are under development. Therefore, this study investigated that CO$_2$ absorption/regeneration of Sodium-based dry sorbent and the effect of SO$_2$ concentration in the fixed bed reactor. The dry sorbents were prepared in the condition of different PVA contents and calcination temperatures. As the results of this study, BET surface area showed 832.79 m$^2$/g and SEM result showed possibility as dry sorbent due to having of much micropore distribution. Also, the fixed bed reactor showed decreased CO$_2$ absorption capacity with SO$_2$ injection, because of the generation of $Na_2SO_3$ and $Na_2SO_4$.

The reality which cannot protect existing tangible intangible modern cultural heritage in Daejeon is makes historical value and identity of a city weakened and then, this leads to absence of the foundation of urban regeneration based on the history. References as recording inheritance indicates characteristics or identity of the area and they represent the physical mental symbol of the area; images of diverse structures or sceneries with historical or cultural characteristics are contents of urban regeneration based on history and culture, which can be utilized as historical sources to verify realness of disappearing modern cultural heritage. Therefore, understanding and utilization of modern cultural heritage through this study on regional archiving can be deemed to be the first stage to bring community spirit, affection and pride to local residents. In this connection, this study intends to suggest a policy direction not only to maintain realness of modern cultural heritage through preservation and utilization but also to expect formation of settling and fellowship as well as cultural economical effect from the viewpoint of urban regeneration.

This study was conducted to analyze problems related to non-water-soluble sanitary products during the treatment of water regeneration centers in E.T.F. and S.T.F. at a time when the demand and supply of non-water-soluble sanitary products are increasing. As a result, the improvement plan of the W.R.C. should focus on pretreatment facilities. When replacing facilities in the future, various dust removers suitable for the facility's reality will be installed in the pretreatment of S.T.F., and it is proposed to link a bar-racks screen with a comprehensive treatment device or install a comprehensive treatment device for impurities alone in the pretreatment of E.T.F.. In addition, a microscreen screen must be installed on the front end of the excretory treatment unit. to separate non-water-soluble materials, and it is necessary to secure a maintenance space for the excretory treatment unit.

The purpose of this study is to derive the linkage between urban regeneration and district unit planning, in order to supplement the limitations of the spread of the effects of individual urban regeneration projects. To this end, institutional changes and previous studies with theoretical backgrounds were reviewed, the urban regeneration strategic plan and district unit plan cases in the spatial scope of Jeju Island were analyzed, and a unified administrative procedure to strengthen linkages was proposed. In addition, when selecting priorities for active regions, we reviewed how to use the indicators of involvement of residents, which enabled the project to be performed smoothly by grasping the participation of residents and the elements of complaints. Also a hypothetical target site was set up and suggested how to establish a district unit plan by type. Depending on the circumstances and environment of the site, the use of the land use plan and the regulation and mitigation of the district unit plan may be appropriately used to expect the inhabitants to expand their participation and revitalization. This study suggests ways to revitalize decayed areas beyond systematic urban planning in connection with systematic plans, to improve administrative procedures, and to promote bottom-up projects.

The purpose of this study is to analyze the cases related to the multi-dimensional urban planning and its related systems that can contribute to the urban regeneration as the policies and projects for stereoscopic city increase. Through the case analysis, urban regeneration function and role of multi-dimensional urban planning are identified as connection of places, activation of local economy, expansion of infrastructure and supply of housing. In the institutional sector, private participation is hindered due to the ban on the establishment of the right to hold state property. In addition, it is difficult to utilize the three-dimensional urban space without land securing at a certain rate based on uniform installation standards of the two-dimensional land use plan, and the problem of insufficient interconnection between law and institution is derived. In conclusion, it should actively support and promote the promotion of the three-dimensional facility with the aim of diversifying the regional infrastructure structure and strengthening the urban function. In addition, development of stereoscopic and compound development should be promoted for old urban areas, and parking lots, underground shopping malls, parking lots, etc. should be installed using the subspaces of parks, schools, roads and traditional markets of old residential areas. Finally, cooperation between the central government, the municipalities and the private sector is necessary for the realization of these urban regeneration projects.

Nosong-dong is used to be center of the administration, education and transportation in Jeonju. It has ironically been the location of the city's prostitution quarter 'called Seonmichon'. This place is recently selected as an area of urban regeneration by Jeonju. The project has involved numerous programs which gradually transfer this place for the women's rights and arts. This paper focuses on exploring the socio-cultural meanings of a community museum, an archive for gender equality, and an exhibition site for local artists. The Seonmichon quarter has long been stigmatized as an area of ill repute and regarded with contempt by the surrounding neighborhood. It is space where polarized interests are entangled. City authority has tried to reflect this by presenting a variety of perspectives on the Seonmichon district. An initiative of the community museum has been its hosting of several exhibitions around the themes of women's rights and community arts. The most remarkable aspect of the exhibitions that have taken place in the heart of the Seonmichon district has been the active participation of local community residents as a catalyst for progressive social change. The paper's overall purpose is to provide an introduction and analyze the process of development of the exhibition initiative, and further examine the social role and meaning of the community museum in Nosong-dong, as well as its future tasks and directions.
