Spatial planning includes various decisions that guide the formulation of land policies, such as planned urbanisation, environment-nature-culture protection, and safe agriculture. Land Administration Systems (LASs) should also include spatial planning decisions as they play a role in facilitating the implementation of land policies. In this study, the Turkish spatial planning system's role in the land administration is discussed. The paper presents the necessity of designing and standardising the spatial planning system as data model. This data model design includes not only spatial plan decisions but also documents that guide spatial planning and land development decisions caused by planning. Therefore, this study aims to present a standardised model of the Turkish spatial planning system and the land use rights, restrictions and responsibilities established by spatial plans. Designing spatial planning system information as a conceptual data model within the Land Administration Domain Model is expected to support land administration system-based improvements.

In Turkey, during the realisation of the land registry and cadastre transactions, manually checking the official documents exceeding 20 million annually causes some problems in document management and security. This study focuses on managing the official documents as online requested by the land registry and cadastre directorates from the other institutions during these transactions. Therefore, a general external data model based on the LADM has been proposed to manage requested documents during transactions. If web-based applications support the proposed model, access to documents will be faster and easier, and security risk will be reduced.

Cadastre in Turkey is executed as two-dimensional (2D) and parcel-based. The third dimension (3D) on land and real estate is shown in 2D on the map with permanent rights. The use of underground spaces cannot be registered. There are various problems in the registration and mapping of real estates that are under or above these excluded places. The research was motivated by some problems that have taken place in the Turkey 3D cadastre due to the inadequate spatial information systems. For this purpose, it is aimed to design a 3D cadastre country profile that takes into account the Turkish National Spatial Data Infrastructure (TUCBS in Turkish) land registry and cadastral data model and is compatible with the Land Administration Domain Model (LADM), which is defined within ISO 19152. In this study presents a detailed overview of the Turkish legal cadastre system and a proposal for realisation based on international standards.

The concepts of three-dimensional cadastre (3D) and property ownership led to increased interest in land use management and research towards the end of the 90s. Within the scope of these studies, international standards and definitions have been realised. In Turkey, there are some academic studies available. However, there are not many studies conducted on an institutional basis. Turkey cadastre carried out by the General Directorate of Land Registry, and Cadastre (GDLRC) are kept. In this context, a 3D RRR (Right, Restriction and Responsibility) for Turkey-based cadastral data model design and development is essential in terms of not constitute a base for the study. The fact that these studies are in the context of LADM and ISO standards and OGC is very important in terms of the fact that the cadastral system is related to international standards..

Investigation of the attitudes of teachers who smoke and those who do not smoke is important in terms of their status for being a role model for their students and for intervention and prevention of smoking in a society. This study investigated the behavior and attitudes about smoking among teachers in a province (Şanlıurfa) in Turkey. The data were collected from 546 teachers from public schools. The participants consisted of 291 female (53.3%) and 255 male (46.7%) teachers. These data were collected by convenience sampling. We used the attitude scale towards smoking. This study indicates that half of the participants were smokers and there were more male smokers than female smokers. Smoker teachers had more positive inclination towards smoking than the non-smokers. Male teachers displayed more favorable attitudes towards smoking than female teachers. The attitude of teachers towards smoking varied according to their cigarette smoking status. Their behavior and attitudes about smoking corresponded well with cognitive dissonance theory.

We conducted microtremor array surveys for shallow S-wave velocity profiles at 20 sites in Bursa, Yalova and Kocaeli provinces in the north-western part of Turkey to provide fundamental data to assess the seismic hazard in the area. All of the measurement sites were positioned very close to strong motion stations belonging to the Disaster and Emergency Management Presidency of Turkey (AFAD) in order to further understand site amplification factors in strong motion records. Of the 20 study sites, two were located in Yalova, four in Bursa and 14 in Kocaeli.We temporarily installed two small arrays to obtain simultaneous records of vertical microtremors. Then, the spatial autocorrelation method was applied to retrieve Rayleigh wave phase velocity curves in a frequency range from 1 to 30 Hz from the array records. The phase velocities in the western part of the Kocaeli area are low across a wide frequency range, while relatively high phase velocities are found in the eastern part of the Kocaeli province. The phase velocities in the Yalova and Bursa provinces are widely distributed suggesting large variations in soil conditions. The observed phase velocity curve at each site was inverted to a one-dimensional (1D) S-wave velocity profile to a depth of 100 m, using a hybrid heuristic inversion method. All the S-wave velocity profiles in the eastern Kocaeli area are similar; however, the sites in the western Kocaeli and Yalova-Bursa areas have profiles with different features from the others.Finally, we discuss amplification factors for S-waves using the inverted profiles. The dominant fundamental periods of the amplification factors were distributed in a frequency range from 0.7 to 5 Hz. The profiles obtained are also used to map average S-wave velocities in the study area, with an addition of existing data at strong motion stations of the AFAD.
