For this reason, a national air quality monitoring network has been developed providing air quality indices. By this network, the quality of the air has been continuously monitored and an important information system has been constructed in order to take precautions for preventing a dangerous situation. The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.

There is an evident correlation between the topographic and climatic properties of a location and the air pollution and air quality on that location. As the variation of air quality is dependent on location, air quality information should be acquired, utilised, stored and presented in form of Geo-Information. On the other hand, as this information is related with the health concerns of public, the information should be available publicly, and needs to be presented through an easily accessible medium and through a commonly used interface. Efficient storage of time-varying air quality information when combined with an efficient mechanism of 3D web-based visualisation would help very much in dissemination of air quality information to public. This research is focused on web-based 3D visualisation of time-varying air quality data. A web based interactive system is developed to visualise pollutant levels that were acquired as hourly intervals from more than 100 stations in Turkey between years 2008 and 2017. The research also concentrated on visualisation of geospatial high volume data. In the system, visualisation can be achieved on-demand by querying an air pollutant information database of 10.330.629 records and a city object database with more than 700.000 records. The paper elaborates on the details of this research. Following a background on air quality, air quality models, and Geo-Information visualisation, the system architecture and functionality is presented. The paper concludes with results of usability tests of the system.

The problem of providing and sustaining compatibility of websites with devices on the market has led to the development of new approaches. As a result of this situation, a responsive web design approach that solves the problem of hardware compatibility has been developed in addition to software and software development methods that allow for the application of this approach. This design approach, which has been more frequently used since 2011, has been preferred by both individuals and companies because it is more sustainable and easier to use. Responsive web design principles and the reasons behind their necessity have been analyzed in this paper. Furthermore, the frameworks that have been developed based on this design approach were analyzed and their characteristics and qualities were compared in reference to responsive web design principles. The criteria necessary for choosing a powerful and effective framework have been laid out.

Research paper thumbnail of An Investigation On The Attitudes Towards Adopting The Design By Coding Paradigm

A/Z : ITU journal of Faculty of Architecture, 2017

In order to manage this new paradigm where the design is becoming more digital, the designer needs to utilize his/her analytical abilities in an effective manner as this is the only way for precise representation of concepts in the actual design itself. The parametric design is a holistic process. A key element of this is the development of design through coding. In this context, the aim of the study was understanding the attitudes of architects and architecture students towards adoption of analytical/algorithmic methods and specifically the object oriented paradigm and design-by-coding. In the first stage a randomly selected group of volunteers were provided training in object oriented programming concepts and design-by-coding over 15 weeks (and a total of 45 hours). Later in this study two data collection tools were utilised to understand the attitudes of the participants towards design-by-coding. The first tool used was an attitude scale, while the second tool used was a web based questionnaire survey. The results indicate that the participants did not show a significant positive attitude towards design by coding. This result might have been caused by the difficulties faced during the study, as the participants were experiencing a design-by-coding exercise as the first time. In fact, it is also observed that algorithmic thinking and parametric design abilities of the designers can be enhanced by training on design-by-coding concepts.

One of the most important reasons for this is the inadequacy in establishing social and environmental relations. This is caused by difficulties in comprehending and identifying the surrounding environment by inhabitants. Comprehensibility of space is essential for establishing a healthy relationship between individuals and the space. In the urban framework, the historical context, spatial relationships and natural / artificial unique features need to be internalized entirely to strengthen the feelings related to relationship and belonging. Thus, the key question can be phrased as “how can the awareness of permanent and temporary inhabitants and comrehensibility of the urban environment be promoted?” Based on this question, this study focused on increasing the awereness and sense of belonging of inhabitants with the help of infographics.

The biggest handicap in the network is the data access problem for instant and time series data acquisition and processing because of its proprietary structure. Currently, there is no service offered by the current air quality monitoring system for exchanging information with third party applications. Within the context of this work, a web service has been developed to enable location based querying of the current/past air quality data in Turkey. This web service is equipped with up-todate and widely preferred technologies. In other words, an architecture is chosen in which applications can easily integrate. In the second phase of the study, a web-based application was developed to test the developed web service and this testing application can perform location based acquisition of air-quality data. This makes it possible to easily carry out operations such as screening and examination of the area in the given time-frame which cannot be done with the national monitoring network.

There is an evident correlation between the topographic and climatic properties of a location and the air pollution and air quality on that location. As the variation of air quality is dependent on location, air quality information should be acquired, utilised, stored and presented in form of Geo-Information. On the other hand, as this information is related with the health concerns of public, the information should be available publicly, and needs to be presented through an easily accessible medium and through a commonly used interface. Efficient storage of time-varying air quality information when combined with an efficient mechanism of 3D web-based visualisation would help very much in dissemination of air quality information to public. This research is focused on web-based 3D visualisation of time-varying air quality data. A web based interactive system is developed to visualise pollutant levels that were acquired as hourly intervals from more than 100 stations in Turkey between years 2008 and 2017. The research also concentrated on visualisation of geospatial high volume data. In the system, visualisation can be achieved on-demand by querying an air pollutant information database of 10.330.629 records and a city object database with more than 700.000 records. The paper elaborates on the details of this research. Following a background on air quality, air quality models, and Geo-Information visualisation, the system architecture and functionality is presented. The paper concludes with results of usability tests of the system.

In order to manage this new paradigm where the design is becoming more digital, the designer needs to utilize his/her analytical abilities in an effective manner as this is the only way for precise representation of concepts in the actual design itself. The parametric design is a holistic process. A key element of this is the development of design through coding. In this context, the aim of the study was understanding the attitudes of architects and architecture students towards adoption of analytical/algorithmic methods and specifically the object oriented paradigm and design-by-coding. In the first stage a randomly selected group of volunteers were provided training in object oriented programming concepts and design-by-coding over 15 weeks (and a total of 45 hours). Later in this study two data collection tools were utilised to understand the attitudes of the participants towards design-by-coding. The first tool used was an attitude scale, while the second tool used was a web based questionnaire survey. The results indicate that the participants did not show a significant positive attitude towards design by coding. This result might have been caused by the difficulties faced during the study, as the participants were experiencing a design-by-coding exercise as the first time. In fact, it is also observed that algorithmic thinking and parametric design abilities of the designers can be enhanced by training on design-by-coding concepts.

One of the most important reasons for this is the inadequacy in establishing social and environmental relations. This is caused by difficulties in comprehending and identifying the surrounding environment by inhabitants. Comprehensibility of space is essential for establishing a healthy relationship between individuals and the space. In the urban framework, the historical context, spatial relationships and natural / artificial unique features need to be internalized entirely to strengthen the feelings related to relationship and belonging. Thus, the key question can be phrased as “how can the awareness of permanent and temporary inhabitants and comrehensibility of the urban environment be promoted?” Based on this question, this study focused on increasing the awereness and sense of belonging of inhabitants with the help of infographics.
