A GENERATIVE APPROACH IN DIGITAL ARCHITECTURE BASED ON TOPOLOGICAL DESIGN

Emine YILDIZ KUYRUKÇU, Hatice Ülkü ÜNAL

Show Abstract

Abstract:

Thanks to the significant changes experienced in architecture at the end of the 20th century and the beginning of the 21st century, numerical algorithms and computational models entered the field of design and a new horizon opened for architects. This new world of architecture not only transformed the design process but also led to the discovery of new methods for design production. In contemporary architectural design, digital media has been increasingly used not as a representational tool for visualization, but as a generative tool for derivation and transformation of form. Approaches of computational and digital architectures to the design problem can be described as deductive and inductive. In the first, a transformation is applied to an object whose result is known. In the second, it is possible to reach the unknown from the data in order to obtain a certain result. Digital modeling software offers a rich repertoire of transformations that a designer can use to further explore the formal potential of an already designed geometry. The end product is topologically the same as the form before deformation. The concept of topology has an important potential for the formation and transformation of form in architecture. The aim of this study is making conceptual analysis of topological design included in the recent design parameters and discussing its place in contemporary and future architecture through architectural examples. In this context, firstly a literature study was conducted, the examples of topological design processes reflected in today's architectural discipline were examined and the results were evaluated.

A QUANTITATIVE ASSESSMENT METHOD RECOMMENDED FOR THE STATE UNIVERSITIES IN TURKEY

Hasan TOSUN

Show Abstract

Abstract:

The university ranking systems have been utilized for academic performance of higher education system in the World since beginning of 2000’s years. These systems, which considered the common parameters, have quickly followed with their own hierarchical measures by higher education organizations. However, these ranking systems never consider  country’s special conditions. This paper mentions the main principles of a new system for state universities performance in Turkey. The quantitative assessment method depends to six separate parameters such as number of publications and projects, teaching quality, teaching income, teaching structure,  the index for entrepreneurial and innovative university and student satisfaction. The technique provides data for well-balanced and justice decision for the national state universitiesthroughout the country. Summation of all numerical values resulted from six parameters represents total score for the related university. The total score obtained for an university also gives its place in the ranking system of higher education in the country. It is possible the central budget to be shared to all state universities in Turkey by means of this method.

A RESEARCH STUDY ON THE EXPANSION OF STATE UNIVERSITIES IN TURKEY

Hasan TOSUN

Show Abstract

Abstract:

The university is a field of science and education where knowledge is produced and transferred to the sectors, teaching is done and individuals are given a profession to use in their lives. For all of these studies, students, faculties and staffs are needed in a higher education institution.   However, in order for studies in the academic field to be carried out correctly, these members must be presented at the University with the appropriate rates. In recent years, the number of students in the universities of Turkey has increased without conforming to some qualification ratios. This study depends on the data of 2010 to 2014.  The number of total students range from 1 741 719 to 2 397 188 within this period.  In this paper, the number of students as university stakeholders are presented according to the university categories, and the effect of student numbers on education quality are evaluated on the basis of different levels of study (pre-undergraduate, undergraduate, graduate) in Turkey.  The study indicates that the rate of expansion to Turkish universities is quite high, when compared with those of the developed countries.

DEVELOPMENT OF ANTIBACTERIAL TOOTHPASTE FORMULATION USING NATURAL RAW MATERIALS

Duygu ÅžAHÄ°N, Burak SAKA

Show Abstract

Abstract:

New treatment methods are very important in the treatment of oral cavity diseases such as tooth decay, gingivitis, and general oral infections. Essential oils have long been used as antibacterial agents due to having biologically active compounds with important health effects. This study aimed to assess the antibacterial and antibiofilm effects of toothpastes with clove and thyme essential oils and propolis extract against bacteria associated with oral diseases. Toothpastes were formulated with 3% concentrations of the clove and thyme essential oils and propolis extract and evaluated for antibacterial and antibiofilm activities. For this purpose, antibacterial activity of toothpastes against Staphylococcus aureus ATCC6538 bacteria were determined and maximum antibacterial activity was observed with clove oil.

THE ADAPTATION AND VALIDITY OF SARC-F SCALE IN INDIVIDUALS OVER THE AGE OF 65

H. Cansın KIŞ, K. Esen KARACA

Show Abstract

Abstract:

This study aimed to investigate the effects of eating habits on sarcopenia in individuals over 65, to adapt the SARC-F scale which is used for the early diagnosis of sarcopenia into Turkish and to investigate the validity of the scale in individuals over 65. The research was conducted with 91 subjects, including 45 females and 46 males, who presented to Mersin Private Akademi Hospital. A questionnaire that consists of general information, anthropometric measurements, MNA screening test and the SARC-F scale was administered to all participants. Relationship between the MNA screening test, which is used to evaluate nutritional status, and the SARC-F scale, which is used for the early diagnosis of sarcopenia, was found to be statistically significant (p=0.001). Evaluating the MNA test and SARC-F scale according to gender, it was found that there was a statistically significant relationship between the SARC-F score and gender (p=0.004), whereas there was no relationship between the MNA score and the same (p>0.05). According to the sarcopenia risk status, there was a statistically significant difference in terms of body weight, height, fat-free mass, hand grip strength and finger grip strength. Statistical evaluation that was conducted to check the reliability of the SARC-F screening test revealed a Cronbach's Alpha value of 0.60. Evaluation of validity showed that the KMO value was higher than 0.50 and the factor analysis was reliable since the Bartlett's Test provided statistically significant results. In conclusion, eating habits that involve a sufficient and balanced diet have positive effects on the prevention and treatment of sarcopenia and the Turkish version of the SARC-F scale is valid and reliable.

TRACKING BUSINESS INTELLIGENCE RESEARCH TRENDS: A BIBLIOMETRIC APPROACH

Ardita DORTI, Ömür AKDEMIR

Show Abstract

Abstract:

Business intelligence is considered as a fundamental necessity for any type of organization. The field of business intelligence has shown continuous enhancements and has kept pace with rapidly changing business environments. The purpose of this study is to explore research trends in scientific articles pertaining to business intelligence. The data set was extracted from the Web of Science and bibliometric method was used to analyze keywords. After the identification of research trends based on frequency, co-occurrence analysis was used to construct and visualize a bibliometric network. The results comprise twenty-nine research trends and four visualizations of the network based on frequency of occurrences, average publication year and densities. Practitioners and scholars may benefit from this study to gain an understanding of the past research in business intelligence field.
