The purpose of this study is to develop a platform tentatively named the Korean Integrated Disaster Evaluation Simulator (K-IDES) to assess building risk during disasters. In this study, the first step includes an analysis of FEMA’s risk management series in the USA for precedent research. Among them, FEMA IRVS is selected as the case study for the development of the K-IDES framework and through the comparative analysis of domestic building design guides, codes, and special acts related to disasters. The next step is to develop a risk assessment methodology to yield quantitative results. This methodology consists of classification systems, calculation methods, and grade ratings. Based on it, K-IDES will establish a management system that can systematically integrate the collected information by using assessment techniques for elements except legal standards to measure risks in response to various disasters and present a classification system of evaluation factors, criteria for evaluation items, and risk assessment methods. In the next study, and through the simulation of the selected buildings by using this risk assessment, a check-list will be verified. The final goal of this study is to build a platform to be used as an integrated risk management method against a complex disaster by the expansion to other types of buildings through continuous data scaling and management systematization.
本研究的目的是开发一个平台,暂定名为韩国综合灾害评估模拟器(K-IDES),以评估灾害期间的建筑风险。在本研究中,第一步包括分析美国联邦应急管理局的风险管理系列,以进行先例研究。其中,选择FEMA IRVS作为K-IDES框架开发的案例研究,并通过对国内建筑设计指南、规范和与灾害相关的专项法案的比较分析。下一步是发展一种风险评估方法以产生定量结果。该方法包括分类系统、计算方法和等级评定。以此为基础,K-IDES将建立除法律标准以外的其他要素评价技术,将收集到的各种灾害危险性评价信息进行系统整合的管理体系,并提出评价要素、评价项目标准、危险性评价方法等分类体系。在接下来的研究中,我们将通过使用该风险评估对选定的建筑物进行模拟,从而验证检查清单。本研究的最终目标是通过持续的数据缩放和管理系统化,构建一个平台,作为针对复杂灾害的综合风险管理方法,扩展到其他类型的建筑物。

Evaluating the Emission of CO2 at Traffic Intersections with the Purpose of Reducing Emission Rate, Case Study: The University of Nigeria, Nsukka 以降低排放率为目的的交通路口二氧化碳排放评估,案例研究:尼日利亚大学,恩苏卡

Traffic congestion is a major problem around the world that results in slower speeds, increased trip time, and a longer queuing of vehicles. The production and use of fuels for vehicles results in emissions of greenhouse gases (GHSs), besides carbon dioxide, which include methane and nitrous oxide. Traffic lights that wirelessly keep track of vehicles could reduce journey time and fuel consumption thereby reducing carbon emissions. In view of the importance of vehicles as an emitter of GHGs, namely CO2, with the growing concern about climate change, this paper aims to explore the emission of CO2 from vehicles at a traffic intersection for the purpose of reducing emission rate. Realizing this reduction, points to the implementation of an Advanced Traffic Management System (ATMS) with Wireless Sensor Networks (WSNs) on the road network of a region will be discussed. With such a technology, a region can experience lower queue lengths at an intersection and therefore lower CO2 emission surrounding the area. The University of Nigeria, Nsukka (UNN) is used as a case study in exploring this phenomenon which over the years has seen a drastic increase on the amount of cars on the campus area. With the assumption that an ATM system with WSNs is deployed on the UNN campus area, the paper looks into the traffic dynamics that makes it possible to evaluate CO2 emission at traffic light intersections to ensure a cleaner environment. Throughout the paper, it will be made clear that with the relevant equation of CO2 emission and the arrival time per vehicle, CO2 emission rate can be evaluated at a traffic intersection depending on the volume of cars at the intersection. With such evaluation, further analysis can be made on ways to actually reduce CO2 emission and techniques for implementation with an ATM system.
交通拥堵是世界范围内的一个主要问题,它导致速度变慢,旅行时间增加,车辆排队时间延长。车辆燃料的生产和使用除了二氧化碳外,还会排放温室气体(ghs),其中包括甲烷和一氧化二氮。无线跟踪车辆的交通信号灯可以减少行驶时间和燃料消耗,从而减少碳排放。鉴于车辆作为温室气体,即CO2的排放源的重要性,随着人们对气候变化的日益关注,本文旨在探讨交通路口车辆的CO2排放量,以降低排放率。为了实现这一减少,我们将讨论在一个地区的道路网络上使用无线传感器网络(wsn)的高级交通管理系统(ATMS)。有了这样的技术,一个地区可以在十字路口经历更短的排队时间,从而减少该地区周围的二氧化碳排放。尼日利亚恩苏卡大学(UNN)被用作研究这一现象的案例,近年来校园内的汽车数量急剧增加。本文假设在UNN校园区域部署了一个带有WSNs的ATM系统,研究交通动态,从而可以评估交通灯十字路口的二氧化碳排放,以确保更清洁的环境。在本文中,我们将通过CO2排放量和每辆车到达时间的相关方程,通过交叉口的车辆数量来评估交叉口的CO2排放量。通过这样的评估,可以进一步分析实际减少CO2排放的方法和使用ATM系统实现的技术。

Using systems thinking and ecologically-reflexive planning, this study examines conceptual opportunities for resilience and regeneration of the historic northwestern Hungarian municipality of Kőszeg and its surrounding bio-region. It will explain how the town and bio-region's socio-cultural and socio-technical systems —its historic heritage coupled with existing and new industrial, commercial, and infrastructural services (energy, water, sanitation, and waste)—can be placed into a regional development scheme that optimizes the vitality and resiliency of these collective systems, following the principles of a circular economy. This study assessed opportunities for Kőszeg, as one example in the region; to revitalize its economy and its local environment based upon attaining a high level of integration among its multi-dimensional resources. Conceptual strategies for practical solutions to town and bio-regional revitalization and resiliency are discussed.

The current state of the electrical sector in Praia (Cape Verde capital city) is characterized by the high cost of electricity and high levels of technical and commercial losses which is caused by the lack of resources of fossil origin. It is also aggravated by an inadequate investment policy forcing a deep restructuring of the entire sector. In order to take advantage of the existing local natural resources and to have a more efficient, robust, and a fair electric system, it seems inevitable to bet on innovative, intelligent, and secure technology which allows tight integration of renewable energy –mainly wind and photo-voltaic energy. In this regard, the present article discusses the economic, social, and environmental impacts of a smart grid for Praia city. Based on a proposed SG architecture that integrates the existing endogenous resources and technologies, it was possible to identify the main advantages and challenges that the implementation of SG technologies would have for the city.
普拉亚(佛得角首都)电力部门的现状特点是电力费用高,由于缺乏矿物来源的资源而造成的技术和商业损失高。不充分的投资政策迫使整个行业进行深度重组,也加剧了这种局面。为了利用当地现有的自然资源,并拥有一个更高效、更稳健、更公平的电力系统,似乎不可避免地要把赌注押在创新、智能和安全的技术上,这些技术可以使可再生能源(主要是风能和光伏能源)紧密结合起来。在这方面,本文讨论了智能电网对普拉亚城市的经济、社会和环境影响。基于集成了现有内部资源和技术的拟议SG架构,可以确定SG技术的实施将为城市带来的主要优势和挑战。

Pub Date : 2018-12-31 DOI: 10.21625/ESSD.V3ISS2.379
Yingyi Zhang, M. Schnabel
The concept of Form-Based Code is of central importance in American New Urbanism. There is an increasing concern on Form-Based Code’s components and adoptions in cities and countries in the USA. This paper aims to extend Form-Based Code’s study to high-density cities of Asia. It explores the methodology of embedding parametric thinking into the multi-scenario evaluation of Form-Based Code. The methodology framework is developed by taking advantage of parametric modelling instruments which visualizes the coding procedure on software interfaces. Using Tsim Sha Tsui, Hong Kong as the experimental site, the paper concludes with a parametric evaluation system towards a walkable and accessible environment in the volumetric urban morphology of high-density cities.

Green infrastructure has been used for environmental conservation and management with many similar concepts such as green-space network, green-link network, and green-ways network based on the objectives of the cities for greening. Seoul established the 2030 Seoul City Master Plan that contains green-link network projects to connect critical green areas within the city. However, the plan does not have detailed analysis for the green infrastructure to incorporate land-cover information to many structural classes. This study maps green infrastructure networks of Seoul for complementing their green plans with identifying and ranking green areas. Hubs and links that are the main elements of green infrastructure have been identified through incorporating cadastral data of 967,502 parcels to 135 of land use maps using Geographic Information System. The study extracted 1,365 of green areas that represent an area of 24,530 ha within the city and buffered these areas to identify districts as critical green areas that have hubs and links. At a city scale, the study used 103,553 of parcel data for ranking extracted 20 districts, and 17,860 of parcel data for ranking extracted 42 links connecting the districts. At a district scale, this study used 87,826 of parcel data for analyzing the status of potential links within the districts and ranking these districts for green infrastructure. This assessment analyzes the main elements of green infrastructure and suggests site prioritization for green infrastructure under variable scenarios of green and developed areas in a metropolitan city.

Adaptive Strategies for Mud Shell Robotic Fabrication 泥壳机器人制造的自适应策略
Pub Date : 2018-12-31 DOI: 10.21625/essd.v3iss2.382

The digital fabrication of monolithic shell structures is presenting some challenges related to the interface between computational design, materialist, and fabrication techniques. This research proposes a singular method for the sequential robotic spray deposition in layers of diverse clay mixes over a temporary fabric form-work pulled in between peripheral and cross section arches. This process relies mainly on the continuity of the construction phases for stability and durability but has encountered some challenges in physical tests related to sagging, displacement, and deformations during the robotic deposition of the material. Adaptive strategies during the digital fabrication stages are proposed for a sequential exploration of the geometry, structural analysis, and construction techniques. Alternative adjustments of protocols for the robotic material deposition include both predictable and unsuspected behaviors preventing the structure to reach non-viable geometric thresholds. Two case studies of physical tests describe, analyze, and simulate some of these strategies and identify specific parameters inquiring the sequential adjustments of the robotic material deposition. These strategies will drive future full-scale tests within a sustainable use of materials and adaptive construction methods, seeking an optimized structural performance that could open a new chapter for the digital fabrication of earthen shells.
单片壳体结构的数字制造在计算设计、材料和制造技术之间的接口方面提出了一些挑战。这项研究提出了一种单一的方法,连续的机器人喷雾沉积在不同的粘土混合层在一个临时织物形式工作拉在外围和横断面拱门之间。该工艺主要依赖于施工阶段的连续性,以确保稳定性和耐久性,但在机器人沉积材料期间,在与下垂、位移和变形相关的物理测试中遇到了一些挑战。在数字化制造阶段提出了自适应策略,以对几何、结构分析和施工技术进行顺序探索。机器人材料沉积方案的可选调整包括可预测和不可预测的行为,以防止结构达到不可行的几何阈值。物理测试的两个案例研究描述、分析和模拟了其中的一些策略,并确定了询问机器人材料沉积顺序调整的具体参数。这些策略将推动未来在材料可持续使用和适应性施工方法方面的全面测试,寻求优化的结构性能,为土壳的数字化制造打开新的篇章。

This paper proposes the synergistic method as an alternative approach that embraces urban complexity and reverses it to a set of mutually reinforcing improvement strategies. After illustrating the general idea of synergistic improvement by examining the correlation among a number of urban issues, this paper uses the case study to explore this inter-connectivity in further details. Hikifune in Tokyo was selected as a case study because of its distinct atmosphere, historical background, and fragility in terms of demographics, natural hazards, and economics. Relevant literature, along with the empirical and statistical data, is the primary method used in this research. Relying on the discovered findings, the conclusion returns the discussion to the necessity for a synergistic improvement.

Relying on the discovered findings, the conclusion returns the discussion to the necessity for a synergistic improvement.","PeriodicalId":137433,"journal":{"name":"International Journal of Environmental Science & Sustainable Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127463487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors, starting from the examination of the historic data of Palermo landscapes on the south-east side, draws up an analysis of the landscape by illustrating the environmental characteristics and the intervention of man in its transformations. Therefore, determined by a certain point to refer to, the author, on the basis of archival, literary, and existing graphic documentation, has therefore sought to illustrate the evolution of the landscape in the geographical area of Maredolce while still presenting relations with the territory of Palermo. Examining the diaries at the end of the eighteenth century with the help of the water colored planks of the sites taking into account the great patrimony left by landscape painters of the period brought a great deal of information. In this sense it is possible to evaluate the transformation of Maredolce from swampy and abandoned land of the last seventeenth century (end of sugary activity) to that of new irrigation agriculture. Transformation that is common to the entire territory of Palermo, with which numerous comparisons are also carried out on the basis of archival documentation. With the introduction of the industrial economy of the citrus which has wiped out any past historical stratification; before being swept by the cementation of the ‘Conca d’Oro’ which still lasts and of which Maredolce (historic palace and its garden) is the last environmental and cultural heritage as a holistic ecosystem that should absolutely be saved by using integrated urban planning with responsible architectonic restoration approaches.
作者从研究巴勒莫东南侧景观的历史数据开始,通过说明环境特征和人类在其转变中的干预,对景观进行了分析。因此,由于确定要提及某一点,作者在档案、文学和现有的图形文件的基础上,试图说明Maredolce地理区域景观的演变,同时仍然呈现与巴勒莫领土的关系。在18世纪末的日记中,借助这些遗址的水彩木板,考虑到这一时期风景画家留下的巨大遗产,带来了大量的信息。从这个意义上说,我们有可能评估马雷多尔奇从17世纪晚期的沼泽和废弃土地(糖活动的结束)到新灌溉农业的转变。这是巴勒莫整个领土的共同变化,在档案文件的基础上也进行了许多比较。随着柑橘工业经济的引入消除了过去任何历史上的分层;在被“Conca d’oro”加固之前,它仍然存在,Maredolce(历史宫殿及其花园)是最后的环境和文化遗产,作为一个整体生态系统,绝对应该通过综合城市规划和负责任的建筑修复方法来保存。
