Under the powerful influence of economical and social transformation, namely Post-Industrialization since the 1980's, old industrial cities in western europe faced a severe urban crisis such as high unemployment rates, demographic decline, urban slums, lack of infrastructures and economic shocks. In order to overcome their urban decline, They had to attempt to find a creative re-modelled and re-imaged Urban Development Strategy for the future. Thus Urban Regeneration has been a serious issue of debate in europe. First of all, Urban Regeneration based on cultural strategy have played an increasingly important role in the Post-Industrial cities and regions since 1980's. The purpose of this study is to find out the organized characteristics of Urban Regeneration based on Cultural Strategy by analyzing successful overseas case "Landesgartenschau in Ruhrgebiet, Germany, where has been changed from an old industrial city to a Culture-Service- based City significantly over last several years. It's inner-city old industrial areas with amount of derelict under-used industrial Heritages have been remodelled and reimaged to a creative and attractive public spaces involving Arts and cultural activity by Urban Regeneration based on Cultural Strategy, namely, "Landesgartenschau".

본 연구는 도시재생 관련 선행연구와 도시재생 사례 분석을 통해 도시재생 유형을 도출하고, 대전시 도시정비사업에 대해 분석한 후, 기존의 물리적 환경에 의해 구분되는 도시정비사업의 문제점을 검토함으로써, 도시재생의 취지에 맞도록 물리적 환경뿐만 아니라 사회, 경제, 문화적 환경의 특성을 고려하는 도시정비사업의 유형화를 제시하는 데 목적을 두고 있다. 이를 위하여 대전광역시를 사례대상지로 도시정비사업을 중심으로 유형화 실태를 살펴보았으며, 도시정비사업의 문제점과 그를 해결하기 위한 도시정비사업(지구)의 유형화 방안을 제시하였다. 세부내용으로는 도시재생 관련 선행연구와 사례를 통해 정리한 도시재생의 유형을 정리하고, 도시재생의 유형으로 물리 환경 재생, 사회 문화 재생, 경제 산업 재생으로 구분하여 이러한 필요한 공간정보를 구축하기 위한 방법론을 제시하였으며, 이를 기반으로 대전광역시의 도시 및 주거환경정비기본계획의 202개 정비예정구역을 대상으로 적용하였다.

In this paper, the electromagnetic damper (EMD), which is composed of a permanent-magnet rotary DC motor, a ball screw and a nut, is considered to be analyzed as a semi-active damper. The main objective pursued in the paper is to study the two degrees of freedom (DOF) model of the semi-active electromagnetic suspension system (SAEMSS) performance and energy regeneration controlled by on-off and continuous damping control strategies. The nonlinear equations of the SAEMSS must therefore be extracted. The effects of the EMD characteristics on ride comfort, handling performance and road holding for the passive electromagnetic suspension system (PEMSS) are first analyzed and damping control strategies effects on the SAEMSS performance and energy regeneration are investigated next. The results obtained from the simulation show that the SAEMSS provides better performance and more energy regeneration than the PEMSS. Moreover, the results reveal that the on-off hybrid control strategy leads to better performance in comparison with the continuous skyhook control strategy, however, the energy regeneration of the continuous skyhook control strategy is more than that of the on-off hybrid control strategy (except for on-off skyhook control strategy).

The old city centers of local metropolitans have lost their functions as CBD in korea. Those old city centers have an only role as a gate connected to the new CBD. This study aims to present regeneration stratigies of old city centers through Osaka case study. This research has been focused on the physical and environmental factors in urban regeneration. There are 4 strategies for old city centers. First, the strategy to attract people to the old city centers is high-density and mixed-use development having functions like shopping, entertainment, residence. This kind of development makes local metropolitan cities compact cities to protect urban sprawl. Second, strategy to give old city centers an identity is to conserve traditional culture and structures and to revitalize retail market. Third is to make pedestrian-friendly street system. Osaka ism't pedestrian friendly but remodelling the connect the pedestrian path to the culture facilities. Fourth is to have water and green environment. Green space is the strong factor that pull people to old city centers.

This study summarizes the recent cutting-edge approaches for dentin regeneration that still do not offer adequate solutions. Tertiary dentin is formed when odontoblasts are directly affected by various stimuli. Recent preclinical studies have reported that stimulation of the Wnt/β-catenin signaling pathway could facilitate the formation of reparative dentin and thereby aid in the structural and functional development of the tertiary dentin. A range of signaling pathways, including the Wnt/β-catenin pathway, is activated when dental tissues are damaged and the pulp is exposed. The application of small molecules for dentin regeneration has been suggested as a drug repositioning approach. This study reviews the role of Wnt signaling in tooth formation, particularly dentin formation and dentin regeneration. In addition, the application of the drug repositioning strategy to facilitate the development of new drugs for dentin regeneration has been discussed in this study.

this study was focused on the effects of fire on spatial change of vegetation landscape in rural region. Fire types recognized as erown fire, severe surface fire and light surface fire in order of increasing intensity were described in a fire map. GIS was introduced to understand the relationship between fire types and topographic conditions or vegetation types. We also investigated land-use type and regeneration strategies after burning. Fire intensity depended on topographic conditions and vegetation types. Special land-use type in this area was collection of edible mushroom (Tricholoma matsutake). Mushrooms had been obtained from Pinus densiflora forests existing as edaphic climax or managed artificially. Regeneration strategy in burned areas was to make sprouts from burned oak stumps. A higher density and growth rate of sprouts, as compared to those on unburned areas, facilitated vegetation succession from P. densiflora forest to oak forest and consequently led to change of landscape pattern.

Conversion of the building can be a core strategy to activate the urban regeneration. Especially in the decayed district, the conversion or retrofit of old building can be a core catalyst to stimulate the urban regeneration. Throughout the case study, a conversion from office to dwelling, there were figured out the design strategies to respond to spatial, functional requirements. The results are as follows ; 1) The main design strategy is to articulate the space by embedding the wall, mass in the rectangular space. 2) to respond to the small size of space, the flexible, movable wall system Is adopted. This gives the selectiveness to the use of space. 3) to secure the livability of interior space, the buffer zone, a terrace space, is fully utilized. This space acts as thermal buffer zone as well as a semi-interior space.

Evidence shows that nerve injury triggers mitochondrial dysfunction during axonal degeneration. Mitochondria play a pivotal role in axonal regeneration. Therefore, normalizing mitochondrial energy metabolism may represent an elective therapeutic strategy contributing to nerve recovery after damage. Photobiomodulation (PBM) induces a photobiological effect by stimulating mitochondrial activity. An increasing body of evidence demonstrates that PBM improves ATP generation and modulates many of the secondary mediators [reactive oxygen species (ROS), nitric oxide (NO), cyclic adenosine monophosphate (cAMP), and calcium ions (Ca²⁺)], which in turn activate multiple pathways involved in axonal regeneration.
