THE UNBEARABLE LIGHTNESS OF GLASS: TRANSPARENT ARCHITECTURE

The heaviness or lightness effect of a building that left to the user changes according to some different features such as its form, relation to topography, structure, fullness-emptiness rate of mass,organization and etc. The organization which gives the best lightness effect is transparency that is provided both with fullness-emptiness and material. The most valid material of transparency thatprovides lightness effect on the perception of façade is glass. Glass which made progress parallel to the development of technology in modern period turns into the skin of building now. In this studyfirstly, the development process of building façades on the basis of material from past to present –from heavy to light- is discussed. Then, the glass buildings that built in both new and historicalenvironments are evaluated in terms of the heavy-light effect

Anthropometric Evaluation of the Crèches Children Furniture in Turkey

The dimensions of the living and working space and buildings, the types of material and different riggings should be designed to conform to the users’ anthropometric measures. The first requirement to design on ergonomic system is to measure the human being who will work and live in that system. Because of this, anthropometric measures are the most frequently used ergonomic data during the design process. In this research paper, we attempt to organize a new data base of anthropometric data to use in the design of children’s equipment and furniture used in crèches. A starting point for research on the proper dimensions of crèche furniture is to investigate how the dimensions of furniture reflect the body dimensions and the functional needs of the children using furniture. The anthropometric data of 3, 4 and 5 year-old-children in crèches was used. We report the results of the measurements of 18 anthropometric characteristics of children which constitute a set of basic data for the design of functional spaces and furniture

Anthropometry of Male and Female Children in Crèches in Turkey

This paper presents the results of an anthropometrical survey conducted on male and female children aged 3, 4 and 5 years in Turkey. A set of 18 body dimensions was taken from 154 males and 132 females. It is considered that the 18 parameters are necessary for the design of school furniture, fittings and equipment in order to minimize musculoskeletal, visual and circulatory problems resulting from badly designed elements. This study identified significant gender differences in a set of 18 anthropometrical measures in this subject group

Uygulamalı Bilimler ve Mühendislik

Bir yapının kullanıcı üzerinde bıraktığı ağırlık ya da hafiflik etkisi; yapının formu, topografya ile ilişkisi, strüktürü, kütlenin doluluk-boşluk oranı, yapı yüzeyinin organizasyonu gibi farklı bir takım özelliklere bağlı olarak değişmektedir. Tüm bu özellikler içinde hafiflik etkisini en iyi veren organizasyon, gerek doluluk-boşlukla gerekse malzeme ile sağlanan saydamlıktır. Cephe algısında hafiflik etkisi sağlayan saydamlığın en geçerli malzemesi ise camdır. Modern dönemde teknolojinin gelişmesine paralel olarak aşama kaydeden cam, günümüzde yapı kabuğuna dönüşmüş durumdadır. Bu çalışmada öncelikle geçmişten günümüze yapı cephelerinin malzemeye dayalı olarak -ağırdan hafifenasıl bir süreç geçirdiği ele alınmıştır. Daha sonra camın, gerek yeni gerekse tarihi çevrelerdeki uygulamaları algı üzerindeki hafiflik-ağırlık etkisi açısından değerlendirilmişti

A SUSTAINABLE APPROACH TO MUSEOLOGY FOR THE FUTURE OF CULTURAL HERITAGE: ECOMUSEUM

WOS: 000591682500022The second half of the 20th century has witnessed many social, political, and economic developments on a global scale and affected people. These developments affected the understanding of museology especially after the 1970s and brought sustainability to the fore in the context of preserving and transferring cultural heritage to the next generations. Maintaining and protecting a country's cultural heritage is essentially a political vision, but with the support of the architectural community, arousing a qualified traditional and cultural awareness will bring the architectural productions to a high level in the country. Therefore, the conservation of cultural heritage and transferring it to other generations is very important in terms of cultural sustainability, collective memory formation. the study deals with the "ecomuseum" concept, which stands out as a sustainable method for the preservation and survival of the natural and cultural heritage of traditional settlements. For this purpose, the ecomuseum concept has been researched in literature and its theoretical framework has been determined. Then, a total of 12 ecomuseums operating in different countries of the world were selected by the survey method. When determining the examples, firstly, ecomuseums, which attract attention with their traditional architectural texture, host a remarkable heritage in this sense and are active today, were preferred. the samples were analyzed with qualitative data analysis and evaluated in the context of founders, operators, exhibition spaces, exhibition objects, and the number of visitors. Besides, the strengths, weaknesses, opportunities, and threats of the ecomuseums, in general, were revealed through SWOT analysis. It has been determined that more than 600 ecomuseums are active around the world today. Although the ecomuseums have the same principles and goals, it has been observed that they differ from each other in the context of their establishment, operation methods, and the heritage resources they exhibit. These differences between ecomuseums should not be perceived as polyphony, but as the richness of different experiences, by this means they can guide new initiatives. However, in some ecomuseums, it is seen that the local people tend to obtain financial benefits before preserving their heritage due to the lack of sufficient knowledge of what the ecomuseum means. This situation is dangerous for the future of the ecomuseums. For this reason, the lack of awareness of the public -both local people and tourists- was considered as the weakest aspect of organizing the ecomuseum. in ecomuseum initiatives, this problem should be resolved immediately. It is essential in terms of eliminating many weaknesses and threats such as damage or harm caused by lack of knowledge, inability to own, unconscious consumption, and adjustment problems. Although the local people do not take an active role in the initial stage in most cases, they get involved in the process and adopt it as the level of their awareness increases. the well-preserved heritage is a powerful resource not only for tourists but also for local communities to appreciate their heritage and for the transmission of traditional practices and intergenerational knowledge. This is a situation adopted by the ecomuseum because the main target group of an ecomuseum is its local people and its main purpose is to support and empower a community to develop and manage its cultural heritage. As a result, an ecomuseum is a flexible tool where local people can manage their cultural heritage, first by preserving their traditions and resources, and then by obtaining financial benefits through attracting everyone to their lands to see, learn and experience. in this context, it is thought that the study will present a different perspective on how settlements that have this potential in our country, especially those that have been abandoned or used limitedly for economic reasons can participate in life and how their cultural heritage can be sustained

Cardioprotective effect of metformin against doxorubicin cardiotoxicity in rats

Objective: The clinical use of doxorubicin, which is a strong antineoplastic agent, is limited due to its cardiotoxic side effects. Metformin is a drug with antihyperglycemic effects, and it has been shown to have a cardioprotective effect on left ventricular function in experimental animal models of myocardial ischemia. The present study investigated the cardioprotective effect of metformin in rats with doxorubicin cardiotoxicity

Piccolo in transcatheter PDA closure multi-centre study from premature to adolescent children.

In this multi-centre study, the mid- to long-term efficacy and safety of the Amplatzer Piccolo Occluder in patent ductus arteriosus closure in premature and term infants as well as children were discussed. Methods. Between 2016 and 2021, 645 patients, 152 of whom were less than 1 month old, underwent ductus closure with the Piccolo device from five different centres in Turkey. The median age of the patients was 2.2 years, and the mean narrowest point of duct diameter was 1.8 mm. Sixty-two patients weighed ≤ 1.5 kg, 90 patients 1.5-3 kg, and the mean follow-up was 20.4 months. In 396, the duct was closed by the retrograde route. Ductal anatomy was Type A in 285, C in 72, E in 171, and F in 64 patients. Fluoroscopy duration was 6.2 min. The procedure success rate was 99.1%. Device embolisation occurred in 13 patients (2%), and 11 were retrieved with a snare. Cardiac perforation and death developed in one premature baby. The left pulmonary artery and the descending aorta stenosis were observed in 3 (0.4%) and in 5 patients (0.5%). Results. Piccolo device is safe and effective in closing ductus in all age groups. It has low profile for use in premature and newborn babies, a small embolisation risk, and a low residual shunt rate after closure. Conclusion. The Piccolo device can be considered as close an ideal occluder. The lower profile, smaller delivery catheter size, and symmetry of this device allow for a venous or arterial approach
