- چکیده: ارزیابی و پایش برنامههای مدیریت خطرپذیری از شاخصهای مدیریت هوشمند شهری است. در این تحقیق ضمن تأکید بر الزامات شهر هوشمند، به نقش کلیدی مدیریت هوشمند در پشتیبانی از تصمیمگیری برای پیشگیری، آمادگی و کاهش خطرپذیری کالبدی یک شهر برای زمینلرزه اشاره میگردد. روش مطالعه از نوع کتابخانهای و شامل گردآوری اطلاعات و سوابق موضوع، غربالگری، دستهبندی و تحلیل توصیفی میباشد. بدین منظور از مفهوم پشتیبان تصمیمگیری هوشمند استفاده گردید. نتایج نشان داد با اعمال مدیریت هوشمند و به کارگیری فنآوریهای نوین میزان مخاطرات زمینلرزه کاهش مییابد. شیوههای سنتی از انعطافپذیری، خوداصلاحی و تطابقپذیری لازم برای مواجهه کارآمد با زمینلرزه برخوردار نیستند. کارآمدی الگوی مدیریت هوشمند از طریق مداخله در نظام برنامهریزی کالبدی شهر مستلزم بهرهمندی از سامانههای هوشمند اطلاعرسانی وقوع زمینلرزه و پایش زیرساختهای شهر است که میتوان با طراحی سامانهای، میزان مداخلهپذیری مدیریت شهری را به صورت هوشمندانه در یک شهر و قبل از وقوع زمینلرزه تعیین نمود.
- چکیده انگلیسی: Abstract
Quantitative and qualitative Assessment and monitoring of risk managed planning and crisis management and their examining their effectiveness reveals need for intelligent urban management in terms of physical planning, especially management of natural disasters such as earthquake. Study of strong earthquakes happening in large urban areas that highlight positive effect of crisis management explicitly indicate an intelligent management model with regard to urban physical planning. Present modern cities with a large extent of complexity and intertwined network of connection under the umbrella of high-tech information technology as well as electronic technologies require a revision of traditional approaches together with creative intelligent management. This study not only emphasizes the necessity for the requirements of intelligent cities, including employing digital information systems versus analogue information and inevitability of updating as well as integrating urban physical data, but also elaborates the key role of intelligent management in supporting any kind of decision making in order to prevent, prepare for, and mitigate risk associated with physical fabric in a city in the event of earthquakes. The methodology employed in this study includes literature review, including gathering information and history of the field, screening of this information, and ultimately its categorization as well as descriptive analysis. To this end, theoretical fundamentals of intelligent decision support are taken into consideration. The results show that by employing intelligent management through incorporating physical planning along with modern technology into urban infrastructures, hazards of earthquakes can be mitigated. Using this management approach in urban physical planning is necessary due to rapid expansion of cities. Furthermore, other approaches lack flexibility, self correction, and adaptation required effectively and efficiently to cope with seismic crises. Efficiency of intelligent urban managing model through intervention in physical planning requires benefitting smart seismic-alarm systems and monitoring vital urban infrastructures, where the extent of intervention in urban management within urban physical fabric can be determined in an intelligent fashion and prior to occurrence of earthquakes. The application of intelligent management within the framework of physical planning is an efficient and excellent way of preventing, preparing, coping and relief and rebuilding a city against earthquake crises. Because using the concept of urban intelligent management, decision making for earthquake interventions to confront the earthquake has self-improvement capabilities, flexibility and adaptation to urban variable needs. In this model, an assessment of various urban criteria is undertaken to prevent, prepare and reduce the risk to earthquakes. An analysis of the relationship between physical planning and urban land use and the communication and infrastructure network with the degree of earthquake vulnerability is considered as one of the intelligent management policies in reducing vulnerability. So that any crisis decision, requires intelligent arrangements to support the continuous monitoring of indicators and self-improvement, supporting a variety of methods, replacing indices and creating productivity (flexibility) and supporting Establish future studies and adaptation at all times (adaptability), in order to finally identify the effective variables in the city's vulnerability and create the integrity between intelligent management of efficiency for prevention and preparedness against earthquakes.- انتشار مقاله: 11-10-1348

- چکیده: پراکندهرویی پدیدهای است که تأثیراتی بر کیفیت زندگی دارد. این پژوهش به بررسی رابطه بین کیفیت زندگی با پراکندگی و فشردگی شهری در شهر خرمدره میپردازد. برای انجام پژوهش از روشهای قیاسی، اسنادی و نرمافزارهای GIS، SPSS، LISREL 8.5 و برای تحلیل دادهها از آزمونهای منویتنی، t و تحلیل عاملی استفادهشده است. محلههای شهر خرمدره در دو حوزه پراکنده و فشرده دستهبندی شدند که چهار محله بهصورت تصادفی ساده انتخاب شدند و حجم نمونه برای سنجش آن بر اساس فرمول کوکران 130 عدد محاسبه شد. نتایج نشان میدهد که کیفیت زندگی در حوزه پراکنده بالاتر از حوزه فشرده با اطمینان 95 درصد قرار دارد.
- چکیده انگلیسی: This paper examines the relationship between urban Sprawl and urban compaction with quality of life.
By technology progress and the use of fast means of transportation, the deployment of citydwellers was possible in rural areas around the city. However, due to problems in urban centers (such as high price of housing and land, over population jamming, etc.) population is poured into the suburb and on the other side due to the existence of highways, they were able to meet their requirements easily by refering to urban centers where it was caused spread cities horizontally.
Urban sprawl event was stared at the united states in twentieth century then it was taken in to place in other countries like Iran. And surely conseques of this event have had some effect on quality of life (positive or negative). The purpose of this study is to investigate the effects of urban sprawl on the quality of life and the sample is Khoramdareh city. The main question in this study is that if the urban sprawl affects on the quality of life and how much is it?
Therefore, after the study and examination of the theories, concepts and approaches to the phenomenon of urban sprawl and quality of life, the global experiences in respect of sprawl and quality of life and indicators of their measurement was investigated. First in the evaluation of case study, causing factors of dispersion in Khoramdareh was analyzed and then urban sprawl was investigated by examining 13 factors in 12 urban district. It was divided into sprawl district (1, 2, 3, 4, 10, 11, 12 neighborhoods) and compact districts (5, 6, 7, 8, 9 neighberhoods). Then urban neighberhoods of Khoramdareh gradation based on sprawl from 1 until 12 dirges (11, 12, 10, 1, 4, 2, 3, 5, 7, 8, 9 and 6 neighberhoods). Also quality of life by 18 indexes and questionnaire design by 18 indexes and by filling it in Khoramdeh selected neighberhoods (1 and 11 neighborhoods from sprawl district and 6 and 8 neighborhoods from compact district) were evaluated.
The number of questionnaires was calculated by Cochran formula and the number rose to 130 in the four neighberhoods of Khoramdeh and by Using of this technique, the samples were made to collect data. Then the questionnaire data were analyzed and summarized by using of descriptive statistics tools (tables and charts) and finally analyzed by using of inferential statistical techniques and the results was granted with a certain confidence level of extension. Used analysis includes: Mann-Whitney Test and t Test by using of SPSS16 software and exploratory factor analysis by using the LISREL 8.5 software.
The results show that the quality of life in 1 and 11 neighborhoods (ave = 2/5) is upper than the quality of life in 6 and 8 neighborhoods (Average = 2/22), with 95 percent confidence level.
And then by this 95 percent confidence level, it can be said that quality of life in sprawl neighberhoods is upper than the quality of life in compact neighborhoods.- انتشار مقاله: 01-05-1397
