DETERMINING LEARNING SUCCESS of kNN ALGORITHM on ZOO DATASET

People learn by examining, observing and researching their environment. They actually gains experience from what they have learned. By using the experience they have gained, they can adapt to the new situation they encounter and make decisions. People always make decisions by comparing their previous knowledge while describing objects and classifying them. Similarities and differences to previously learned objects are very effective in decision making. It has been shown in the studies that the experiential learning method can also be used on machines. Intelligent machines and devices that use machine learning methods in their structure are widely used in many areas. Machine learning can be performed using different algorithms. These algorithms use the attributes of the objects in the data set when making decisions. Similarities and differences in the attributes of objects are obtained by comparing them with previous experiences. As a result of the comparison, a decision is made and predictions are made about the classes of the objects. In this study, kNN machine learning algorithm, which is a supervised learning method, was used on the Zoo dataset. In this data set, there are attributes of common living things. By using these attributes, the classes of living things in the data set are determined. The “k” neighbor value and weight parameter selected in the kNN algorithm affect the learning success. In this study, the effect of two parameters used in the kNN algorithm on learning success is shown. According to the results obtained, the "k=1" neighbor value and the "Distance Weight" parameter were selected and the highest success result was obtained.

EFFECT OF DIFFERENT SALINITY AND LIGHT INTENSITY ON THE GROWTH OF PORPHYRIDIUM CRUENTUM

In the study, Porphyridium cruentum was cultured under laboratory conditions at 20±2°C, 16:8 (light:dark) photoperiod and continuous aeration to different salinity (20‰, 30‰, 40‰) and two different light intensities (37 µmol m-2s-1 photon and 110 µmol m-2s-1 photon) and growth was determined. Dry matter, optical density and chlorophyll a parameter were used to determine growth. The best growth was determined in culture with a salinity of 30‰ at 110 µmol m-2s-1 photon light intensity. In this group, the optical density (OD) was 1.504±0.003 and the dry matter amount was 1.327gl-1. In the case of 37µmol µmol m-2s-1 photon light intensity, the optical density values were found to be similar in groups with 30‰ and 50‰ salinity and were found to be 1.234±0.004 and 1.215±0.002, respectively. The amounts of dry matter were also similar; 1.168gl-1 and 1.159gl-1, respectively. While the lowest growth was in the culture at 37 µmol m-2s-1 photon light intensity and 20‰ salinity. The optical density obtained on the last day of this group was 1.165±0.004 and the dry matter amount was determined as 0.986gl-1. The amount of chlorophyll a was determined in the cultured groups at the best 37 µmol m-2s-1 photon light intensity.

ENERGY EFFICIENT IMPROVEMENT OF HISTORIC BUILDINGS: A CASE STUDY IN SINOP

Although historical buildings are ecological with their construction systems and materials, they cannot provide necessary performance in today's comfort conditions and therefore they are abandoned and remain in a damaged or dysfunctional state. Energy efficient improvement works are carried out in historical buildings in order to bring the historical buildings today's conditions, re-use and ensure their sustainability. However, there are many limitations in these studies due to the heritage characteristics of historical buildings. With these limitations, the works to be done should be carried out with the least intervention without damaging the heritage values of the historical buildings. For this reason, it is necessary to specially select the applications to be realized within the scope of energy efficiency in historical buildings and scaling the physical effects of the applications relative to each other. In this context, in this study, it is aimed to reveal the appropriate improvement methods in order to reach the maximum energy efficiency with the least physical intervention, with the techniques suitable for the historical texture by preserving the original qualities in the historical buildings. Based on the Historic England intervention evaluation scale developed in this framework, 5 scenarios, including the current situation and 4 different design scenarios, including interventions from small to large impacts, were created on a sample historical residential building, and the data of each scenario in terms of energy consumption were obtained. Models created within the framework of the scenarios were evaluated with the Design Builder simulation program, and annual heating and cooling loads and the amount of energy consumed per total m² were obtained. Evaluations were made by comparing the energy efficiency of applications at different degrees with the graphics and tables prepared in the light of these data. As a result, suggestions have been developed regarding the interventions to be made to historical buildings according to the intervention effect sizes in the context of energy efficiency with the evaluations made.

The aim of this study was to determine the perspectives of the students of the physiotherapy and rehabilitation department towards the disabled and their attitudes towards the education of the disabled. Sixty-eight volunteer students (50 females, 18 males) studying at Pamukkale University School of Physical Therapy and Rehabilitation and taking the Psychosocial Rehabilitation course in the Spring Semester of the 2020-2021 Academic Year participated in the study. The Attitude Toward Disabled Persons Scale (ATDPS) was used to evaluate the positive and negative attitudes of the students towards the disabled individuals, and the Attitude Scale for the Training of Individuals with Disabilities (ASTID) was used to determine their views on the education of the disabled individuals. Evaluations were made at the beginning and end of the relevant semester. The mean age of the students was 19.44±1.07 years. In the first evaluation, the mean of ATDPS was 50.75±13.92 and the total score of ASTID was 51.04±18.42 points. At the last evaluation, the ATDPS score increased to 78.36±13.77 and the ASTID total score to 93.13±7.48 (p=0.0001). Providing students with basic information about various disability groups and their rehabilitation will increase the level of awareness towards people with disabilities. It is important to develop positive attitudes towards the disabled throughout society in order for the disabled to feel themselves as a part of social life and to increase their participation in social life. It will contribute to the increase of the social awareness of the organizations to be organized regarding the education of the disabled and disabled people. Organizations to be held regarding disabled people and the education of the disabled will contribute to the increase of social awareness.

INITIAL EVALUATIONS OF NATURAL (226Ra, 232Th AND 40K) AND ARTIFICIAL (137Cs) RADIO ISOTOPE ACTIVITIES IN ARZULAR-YITIRMEZ-DÖLEK (GÜMÜSHANE) MINERALIZATION/ALTERATION FIELDS

Within the scope of this study, the first evaluations of natural (226Ra, 232Th and 40K) and artificial (137Cs) radio isotope activities of the Arzular-Yitirmez-Dölek (Gümüşhane) mine/alteration site were carried out. Measurements were carried out with Poptop Ortec gamma rays detector on 22 soil samples collected from the field. When the natural 232Th, 226Ra and 40K activities of the area are compared with the weighted world averages, it has been determined that the 40K and 226Ra activities exceed the world averages in most of the sampling points, and the 232Th activities are below the weighted world average except for a few sampling points. It was observed that the artificial 137Cs activities in the field were above the detection limit and exceeded 2 Bq/kg except for a few sampling points. It has been evaluated that the high 137Cs activities in the field may be associated with a human-induced effect, especially the accident at the Chernobyl nuclear power plant. Parameters such as radiological hazard indices, Ra equivalent activity value, absorbed dose rate and annual effective dose rate were also calculated for the field. Considering the results obtained from these parameters, it was concluded that it would be beneficial to study the Arzular-Yitirmez-Dölek mineralization/alteration field in more detail in terms of natural and artificial radioisotope activities.

HEALTH RISKS THAT CAT SCRATCH DISEASE CREATES IN HUMANS, CONTROL AND TREATMENT CHOICES

It is concluded that animal health affects directly human health considering the fact that major part of diseases in humans result from animals. Bartonella agents are isolated from humans, rodents, rabbits, dogs, ruminants, wild and domestic cats. Bartonella infections are most commonly seen in domestic cats. Cats are considered primary mammalian reservoir in the transmission of zoonotic Bartonella (B.) henselae and B. clarridgeiae infections. Bartonella, vector-borne pathogen commonly appeared in our country and the world, can cause from mild flu signs to severe diseases such as endocarditis, myocarditis, arthritis, hepatitis in humans and animals. After Bartonella infections are transmitted by fleas to cats, cats may remain chronically infected with bacteria for months or years and especially they can transmit the infection to humans by bites or scratches. Cats infected by Bartonella spp. without any clinical signs can transmit the infection to humans. In the context of this review in the light of mentioned knowledge, data were presented for prevalence situations belonging to regions and countries that Bartonella infection commonly occurs in Turkey and the world. In addition, knowledge was given obtained from recent scientific sources for transmission ways of bartonellosis, clinical signs that it causes in humans and animals, diagnosis methods, treatment and control.

RENUMBERING IN CITY WITH HIERARCHICAL CLUSTERING METHOD OF BUS STATION NUMBERS: THE CASE OF KAHRAMANMARAŞ PROVINCE

Bus stations are one of the most widely used components of the public transportation system by citizens. Many critical information, such as the list of bus lines passing through the station, the station-based schedule of the bus lines and when the vehicle operating in the transportation system will pass through the station, are calculated and published according to the station number. For this reason, the station number is being memorable by the citizens and the station numbers of the bus stations, which are spatially close to each other, are numerically very close to each other, are very important in terms of easy learning of the station number. Bus station numbers are usually numbered according to the order in which the line routes pass through the stations. However, considering this case, there is a huge difference between the inconsistency in the station numbers and the station numbers of the stations that are spatially close to each other, when the line route is changed or when the station numbers and the order of passing from the stations are different for different lines passing through the same station. In this study, a hierarchical clustering-based new approach has been proposed to eliminate the problems in bus station numbers and to set bus station numbers that are spatially close to each other. The proposed approach was carried out using the real bus line route and bus station data of Kahramanmaraş Metropolitan Municipality. In the experimental evaluations, the difference between the bus station numbers created by the classical method and the difference of the bus station numbers created by the hierarchical clustering method that spatially close to each other were compared. Experimental results show that the proposed hierarchical-based clustering method creates a closer number of station that are spatially close to each other when compared to the classical method.

INVESTIGATION OF MECHANICAL PROPERTIES OF PIPES WITH BUTT CURVED LAP JOINTS SUBJECTED TO TORSION

In this study, the mechanical properties of steel pipe joints bonded with an acrylic adhesive under torsion were investigated by considering different overlap lengths and curvilinear radii. For this purpose, St-37 galvanized steel pipes with ØD = 21.3 mm outer and Ød = 15.9 mm inner diameters were modeled in three dimensions by creating 8, 10, 12 mm overlapping lengths in male and female form and 30, 40 and 50 mm curvilinear radii on the forehead regions. Numerical analyzes of the created models were performed in the ANSYS Workbench program, and samples with an overlap length of 10 mm were prepared on the CNC (Computer Numerical Control) bench to verify the numerical analysis. The prepared male and female specimens were joined using an acrylic-based DP810 structural adhesive resistant to humid environments, curable at room temperature, and validation experiments were carried out. After the study, obtained numerical and experimental data showed that pipe lap joints subjected to torsional moment with the same lap length but different curvilinear radius have been observed to vary significantly in the amount of load they carry. In addition, as the overlap length increased, the amount of load they carried increased. Also, in this study was compared by performing stress analyzes according to the overlap length and radii of curvature.
