Spatial plans and strategies ensure that urbanization takes place according to predetermined scientific and technical criteria. Urbanization that takes place without taking into account these legal and technical bases lead to the emergence of informal, risky and dysfunctional settlements. Over time, these settlements become increasingly vulnerable due to their failure to meet social and technical requirements, making their sustainability increasingly challenging, and inevitably becoming subjects of urban renewal activities. Google Earth Engine (GEE) platform's archive of satellite images provides temporal monitoring of urbanization on Earth for about 50 years and analysis of changes in the cloud environment. This study investigates whether the GEE platform can use to detect the impact of the areas where settlement activities are carried out without a development plan in the current urban transformation projects in Istanbul. Land use/cover maps classified with the Random Forest algorithm correlate urbanization activities in urban renewal areas with the entry into force date of the spatial plans that guide the settlement. The classification results evaluated in conjunction with statistical tests and spatial plan decisions demonstrate that unplanned urbanization is a serious obstacle to the sustainability of settlements. Additionally, the study results show the performance of the GEE platform in detecting the effects of factors in the urbanization period. The GEE platform can serve as a facilitative tool for deriving lessons from urbanization experiences to inform policymaking. [ABSTRACT FROM AUTHOR]

It is pointed out that even though Land Administration Domain Model (LADM) standards offers a conceptual scheme defining the legal and geometrical components of real estate, it is important to be compatible with other databases (e.g. with land cover data, archive data, land valuation data and taxation data) that may be related to the model. In the model, the archive data model, which is defined as one of the external data structures, provides a class structure in which the information and documents necessary for land registry and cadastral transactions are represented. According to this class structure, necessary information and documents are kept in archive. Thanks to this structure which enables follow-up of transactions, similar transactions are prevented from being repeated. The General Directorate of Land Registry and Cadastre (GDLRC) performs 25 different land registry and cadastral transactions. During these transactions, some documents (e.g. power of attorney, real estate value statement, building occupancy permit, authority certificate, etc.) are requested from various external institutions (e.g. Municipality, Notary, Governor's Office, Court, etc.). Considering the fact that 8 million transactions are made annually, approximately 20 million documents are manually controlled. The manual control of such an amount of documents can cause waste of time and paper and some forgery. There is a need for external data management in accordance with LADM that enables data sharing between institutions to check whether the documents requested from external institutions during the transactions have up-to-date and correct information content. This study focuses on the online management of the information and documents requested by the GDLRC from the Municipality during the land registry and cadastral transactions. In this context, an external data model for the management of relevant information and documents is proposed. A web-based application was developed to prove that the proposed model is feasible. The application made possible the online exchange and inquiry of information and documents in the digital environment. As a result, it has been observed that thanks to the application, the time for the transaction was shortened, no document in paper form was required as the documents were inquired in a digital environment and fraud was reduced.

This study aimed to identify the current land management and cadastre system in Turkey and determine the most appropriate strategy for integrating the current structure with the principles of the Cadastre 2034 vision. In this work, the legal, institutional, and technical (LIT) status of the existing land management and cadastre system in Turkey was determined using a method based on S trengths, W eaknesses, O pportunities, and T hreats (SWOT) and Analytic Hierarchy Process (AHP). Initially, the advantages or weaknesses of the existing land management and cadastre system in Turkey in terms of LIT aspects, opportunities, and threats arising from the external environment were determined by the SWOT matrix. Then, the information obtained concerning the existing land management and cadastre system in Turkey using this matrix was integrated into AHP and the most appropriate strategy was determined in terms of LIT aspects. For the existing land management and cadastre system in Turkey, from the legal point of view, the best strategy with a weighting of 30% was to ‘update the land administration legislation according to the conditions of the day ’ . The best strategy in terms of institutionalization was to ‘disseminate in-vocational training for the training of qualified personnel (28% weighting)’ and the best strategy from the technical perspective was identified as, ‘the use of technical and technologically advanced measurement techniques in spatial data collection (38% weighting)’. The goal in implementing the AHP-Based SWOT method is to improve the quantitative information basis of strategic planning processes. So, SWOT provides the basic outline within which to perform an analysis of the decision situation, and the AHP assists in carrying out SWOT more analytically and in elaborating the analysis so that alternative strategic decisions can be prioritised.

Abstract: This study presents the exergoeconomic analysis and evaluation in order to provide cost based information and suggests possible locations/components in a GDHS (geothermal district heating system) for improving the cost effectiveness. The analysis is based on the SPECO (specific exergy costing) method, and used to calculate exergy-related parameters and display cost flows for all streams and components. As a real case study, the Afyon GDHS in Turkey is considered based on actual operational data. The obtained results show that the unit exergy cost of heat produced by the Afyon GDHS is calculated as average 5624 $/h. The HEX (heat exchanger)-III among all components should be improved quickly due to the high total operating cost rate and relative cost difference. The HEX-I and PM (pump)-V have the highest exergoeconomic factors among all other system components due to the high owning and operating costs of these components. The heat production costs per exergy unit for all the HEXs decrease due to the high exergy destruction cost rate of the system, while the well head temperature and ambient temperature increase. The SPECO method may be used to improve the cost effectiveness according to exergy rates in GDHSs as a thermal system. [Copyright &y& Elsevier]

Multiple Land Administration Domain Model (LADM) related studies have been carried out in two decades. ISO 19152 LADM is an international standard and an abstract, conceptual model covering the land administration domain (including those over land and water and elements above and below the earth's surface). The LADM is considered an important component for managing and developing land administration systems worldwide. In the context of this study's, scientific publications related to LADM are examined to carry out a bibliometric analysis on LADM research from 2012 to 2020. The extent of this investigation is limited to the Scopus database for scientific publications. All databases belong to the most extensive peer-reviewed summary and citation databases. It is noted that this study is based on the same principles as the research published by Paulsson and Paasch (2015), building on existing knowledge and aiming to add value in support to the current development of Edition II of the LADM. In this study, which covers 2012–2020, 175 LADM related scientific publications were found in the Scopus database. When the distribution of publications in journals is examined, Land Use Policy has the most published manuscripts related to ISO 19152 LADM. This analysis considers author identification, type of paper, organisational issues, and bibliometric analysis components. The analysis considered articles, books, and proceedings directly related to the LADM and included in the Scopus database or conference and workshop proceedings. For this, articles and books were selected from the Scopus database. Also, the proceedings were selected from those presented in the International Federation of Surveyors (FIG) events and workshops on LADM. Overall, this paper aims to arrange and present the global scientific production on LADM-based research. • International standards (LADM and ISO) play a vital role in the development of cadastral systems. • This paper aims to determine Global scientific production on LADM-Based research using bibliometric analysis from 2012 to 2020. • At a crucial time for LADM, during its revision process and with several publications since its vote as ISO standard, this bibliometric analysis provides important background for the research carried out so far. Covering an international context and taking into account publications in well-recognised sources, i.e. Scopus and FIG events, the analysis considered criteria according to their content.

• Good governance is required for public administration. • Land administration and its sub-groups are important areas where good governance can be applied. • Good governance index is higher in developed countries. Within the scope of the developments in public administration after the 1990s, "Good Governance" approach has been preferred instead of the traditional public management approach. Good Governance is a fair, impartial and egalitarian management model that is based on co-management and envisages the participation of all actors (e.g. public and private sector, civil society) in decision-making processes. With this new management model, public institutions in Turkey began to realise good governance based reforms, especially in areas where they establish a close relationship with citizens. In this article, changes in the public administration in Turkey together with good governance and the effects. The effects change on the land registry and cadastre processes are discussed. In this regard, a situation is evaluated in the context of the future Government 3.0 process by discussing the successful and incomplete aspects of good governance in land registry and cadastre practice in Turkey.

Abstract: Malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The present study aimed for the first time, to investigate malaria in “donors deferred for malaria risk” and to determine the regional rates of malaria deferral in Turkey. Blood samples were collected from several Blood Banks of southeastern provinces where local malaria cases still exist and from Blood Bank of Ege University Medical School (EUMS) located in western Turkey where malaria is eradicated decades ago. Plasmodium spp. and specific antibodies were investigated by stained smears, antigen detection, PCR and ELISA. Among the donors deferred for malaria risk, Plasmodium spp. were not detected by microscopy, PCR or antigen detection. Seroprevalances were 2% and 3.92% in western and southeastern regions, respectively. Rate of donor deferral for malaria risk was 0.9% in EUMS and deferrals were exclusively because of travel to southeastern Turkey. In southeastern provinces, deferrals were mainly due to malaria like fever history. The present study first time assessed regional rates of donor deferral due to malaria risk in Turkey. Previously, malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The results of the study showed that 97% of the deferrals were unnecessary. In conclusion, to reduce unnecessary donor deferrals in Turkey, in addition to comprehensive questioning for malaria history, the usage of a malaria antibody screening method should be initiated prior to deferral decision.

Abstract: In the present study, to discover how teaching of renewable energy sources in Turkey is carried out at the university level, a questionnaire was developed and applied at different universities in Turkey. The analyses conducted on the data obtained from the questionnaire revealed that education about geothermal, solar and wind energy is given at master’s level, other renewable energy sources are taught at the undergraduate level within the curriculum of some engineering courses. The teaching performed about renewable energy sources is in Turkish and at encyclopedic level. As preparing and obtaining the required materials are costly, some problems are encountered in the teaching of renewable sources. In Turkish universities, no degree about renewable energy sources is granted. Hence, the country must make use of the people having engineering degree to capitalize on its renewable energy sources. As there is no program specializing on providing training about the renewable energy sources, it seems to be difficult to find experts about this issue. The current state of renewable energy sources education seems to be inadequate and it should be expanded and strengthened. [ABSTRACT FROM AUTHOR]
