While clothing is produced and consumed rapidly, it strives to create appropriate forms and to create appropriate identities by giving correct messages; therefore, it is one of the most important fields requiring art and design education. The fashion design student, who forms the infrastructure with basic art education and figure drawing, not only transfers the imagination to the two-dimensional plane with the fashion drawing lesson but also transfers it to the two-dimensional plane; at the same time, he takes art and design education, which is aesthetic education, and feeds his visual vision and mind. In this research, the Fashion Drawing Lesson has been examined in detail in terms of determining the place, position, importance, processing and content of the Fashion Drawing Lesson in the official fashion design curriculum and a comprehensive literature search has been conducted; then the matter has been tried to be examined thanks to a link has been established between education, fashion, art and design disciplines. The course syllabus in Turkey and some of fashion design course programs in the world were examined; the experts providing fashion formal education and the students who received fashion formal education were interviewed face-to-face to obtain information first-hand. First of all, the study started by determining the fashion design undergraduate programs in the OSYM (Assessment Selection and Placement Center) placement guide and examining the course hours, course times and course contents of the fashion formal courses in these programs. The researcher visited the designated universities for the purpose of on-site observation and interview, and conducted semi-structured interview questions and face-to-face interviews with experts and students and recorded them. The transcribed interviews were analyzed using content analysis method and the findings were interpreted within the framework of the research questions. The findings were interpreted and discussed, and after the results were written, suggestions about the study were included. As a result, it has been determined that the admission of students to the fashion design program should be made with the combination of central examination system and talent exam suitable for fashion design education. It was seen that the time granted for the program was not sufficient in mean of implementation of the fashion drawing lessons properly in the fashion design education programs.

The problem of constructing an n-dimensional metric differential geometry based on the idea of a two-dimensional area has given rise to several publications, notably by A. Kawaguchi and S. Hokari (1), E. T. Davies (2), and R. Debever (3). In this geometry the area of a two-dimensional plane element is defined by a fundamental function L(xi, uhk), where the xi are point coordinates and the uhk are the coordinates of the simple bivector representing the plane element. L is supposed to be a positive homogeneous function of the first degree with respect to the variables uij, and to possess continuous partial derivatives up to and including those of the fourth order. With these assumptions the problem of the construction of the metric differential geometry splits into two problems; the first of these is the problem of constructing a metric tensor gij(xr, uhk), and the second is the problem of constructing an affine connexion. We deal with the first problem only in this paper.

Vibration-based diagnostic methods are used for the detection of the presence of cracks in beams and other structures. To simulate such a beam with an edge crack, it is necessary to model the beam using finite elements. Cracked beam finite elements, being one-dimensional, cannot model the stress field near the crack tip, which is not one-dimensional. The change in neutral axis is also not modeled properly by cracked beam elements. Modeling of such beams using two-dimensional plane elements is a better approximation. The best alternative would be to use three-dimensional solid finite elements. At a sufficient distance away from the crack, the stress field again becomes more or less one-dimensional. Therefore, two-dimensional plane elements or three-dimensional solid elements can be used near the crack and one-dimensional beam elements can be used away from the crack. This considerably reduces the required computational effort. In the present work, such a coupling of dissimilar elements is proposed and the required transition element is formulated. A guideline is proposed for selecting the proper dimensions of the transition element so that accurate results are obtained. Elastic deformation, natural frequency and dynamic response of beams are computed using dissimilar elements. The finite element analysis of cracked rotating shafts is complicated because of the fact that elastic deformations are superposed on the rigid-body motion (rotation about an axis). A combination of three-dimensional solid elements and beam elements in a rotating reference is proposed here to model such rotors.
