Space perception and art: The case of Anish Kapoor
No full textMimari eserin deneyiminde, insan ve mekan arasında öznel bir iletişim gerçekleşir; insan, mekanı ve boşluğu, duyuları ile algılar ve mantıksal bir değerlendirmeye varır. Mekan, fiziksel ve zihinsel yapıları bütünleştirirken, bireyin varoluşsal deneyimine sağlamlık ve anlam katar. Mimari me-kanın, çevresinden bağımsız bir varlık olmadığı savunulurken; mekan ve çevresi arasındaki ayrımlar ve bütünleşmeler, boşluklar ile tanımlanmaktadır. Mekansal deneyim şahsi bir durumdur; konu (nesne) ile ilişkili öz (değerlendirme) ise, mekana verilen tepkilerle tezahür eder. Bu anlamda, bedenimiz ve düşünsel deneyimimiz mekansal gerçek olarak kabul edilen imgenin, oluşumunda önemli bir rol oynar. Mimari mekan sınırları olsa da dünyayı temsil eder; bu nedenle dünyaya dair algımız önce mekanda başlar. Bu söylemlere göre, yapılı çevrenin sorumluluğu, varoluşumuzu dün-yada anlama açısından büyük önem taşır. Türk Dil Kurumu’nun tanımına göre mekan "Yer, bulunulan yer, ev, yurt ve uzay" anlamına gelmektedir. Bu tanıma göre mekan kapalı, açık, yarı açık veya uzay gibi boşluğun oldukça sonsuz olduğu bir ortam bile anlam olarak mekanı işaret etmektedir. Bu araştırma, mekan ve boşluk kavramlarını güzel sanatların bir kolu olan heykel sanatı ile birlikte değerlendirilerek, söz konusu boşluğu doldurmaktaki anlamı sorgulamayı hedeflemektedir. Bu amaçla, mekanda boşluk algısını cesur bir ölçek ve yenilikçi malzeme tercihi ile uygulayan, heykelle-rinde malzeme, renk, taşıyıcılık özelliklerine dikkat çeken, sanatçı Anish Kapoor'un çalışmaları, mimari ile kurduğu bağ, tasarım kabulleri yönün-den irdelenecektir. Çalışmanın alt yapısında, mimarlıkla bağlantılı, iç me-kan tasarımı, peyzaj mimarlığı, kentsel düzenleme, malzeme ve yapım tekniği gibi alanlara da değinilecektir.Subjective communication between human and space takes place in the experience of an architectural work; humans perceive and evaluate space and emptiness through their senses and come to a logical conclusion. While space integrates physical and mental structures, it adds solidity and meaning to the individual's existential experience. It is argued that architec-tural space is not an independent entity from its surroundings; distinctions and integrations between space and its environment are defined by emptiness. Spatial experience is a personal state; the subject, object, or value associated with an object is manifested in reactions to the space. In this sense, our body and mental experience play an important role in the formation of the image that is considered spatial reality. Although architectural space has boundaries, it represents the world; therefore, our perception of the world begins in space. According to the definition of the Turkish Language Association, space means "place, location, home, homeland, and space". According to this definition, any environment, even if it is a space such as open, closed, semi-open, or infinite, in terms of emptiness, refers to space. This study aims to question the meaning of filling the void by evaluating the concepts of space and emptiness together with the branch of fine arts, sculpture. For this purpose, the works of the artist Anish Kapoor, who ap-plies the perception of emptiness in space with a bold scale and innovative material choice, and who pays attention to the material, color, and carrying capacity properties in his sculptures, will be examined in terms of its con-nection with architecture and its design concepts. The groundwork of the study will also touch on fields related to architecture, such as interior design, landscape architecture, urban planning, material, and construction technology
Diagnosis and treatment planning with aligners
No full textOrtodontide muayene, tanı ve tedavi planı oluşturmak uzmanlık becerilerinin en önemlileridir. Kişiye özel doğru tedaviyi planlamak için tedavi mekanikleri bilgisi ötesinde hastanın özgün anatomi ve fizyolojisini iyi incelemek ve buradaki bulgulardan yola çıkarak tedavi bilgilerimizi özelleştirerek kullanmak esastır. Şeffaf plaklarla yapılacak tedavilerde rutin ortodonti muayenesi sırasında dikkat edilmesi gereken ve bu teknikle düzeltilmesi zor ya da olanaksız olan problemlerin belirlenmesi önemlidir. Şeffaf plaklarla yapılacak tedavilerde, tedavi planı baştan sonra tüm diş hareketlerinin tam olarak belirlenmesi demektir. Ortodonti uzmanı karşı dişlerin ilişkilerinin öngörüldüğü gibi gerçekleşebilmesi için uygun ankraj planlaması yapmalıdır.Examination, diagnosis and creating a treatment plan are the most important specialist skills in orthodontics. In order to plan the right personalized treatment, beyond the knowledge of treatment mechanics, it is essential to examine the patient's unique anatomy and physiology, and to customize and use our treatment expertise based on the findings. In treatment with aligners, during routine orthodontic examination, it is important to identify problems that need to be taken into consideration that are difficult or impossible to correct with this technique. Using aligners, the treatment plan dictates all tooth movements are precisely determined from start to finish. The orthodontist must make appropriate anchorage planning so that the relationship of the opposing teeth can occur as predicted
Efficacy of laser-activated irrigation with the SWEEPS modality in removing calcium hydroxide from simulated internal resorption cavities
No full textAim: To compare the efficacy of shockwave-enhanced emission photoacoustic streaming (SWEEPS), sonic activation with EDDY, and passive ultrasonic irrigation (PUI) in the removal of calcium hydroxide medicaments from artificial internal resorption cavities. Methodology: Ninety mandibular premolars with single oval canals were prepared to size 50/0.04 and split longitudinally. Standardized cavities were prepared in the apical third of the root canal and filled with calcium hydroxide. The root halves were reassembled and divided into three groups (n = 30) according to the removal methods used. The amount of residual calcium hydroxide was evaluated using a four-grade scoring system. The differences between the groups were analyzed using the Kruskal–Wallis H test (p < 0.05). Results: SWEEPS removed significantly more calcium hydroxide than PUI (p < 0.003) and EDDY (p < 0.035). There was no significant difference between the EDDY and PUI groups (p = 1.000). Conclusion: None of the systems tested were able to completely remove the calcium hydroxide paste from the simulated internal resorption cavities; however, SWEEPS removed more calcium hydroxide than the EDDY and PUI techniques
Evaluation of the validity of mental foramen USG measurements by comparison with CBCT and determination of blood flow
No full textObjectives: To examine mental foramen (MF) morphology and morphometry in comparison with ultrasonography (USG) and cone-beam computed tomography (CBCT), and to determine the relationship between mental artery blood flow parameters and age, gender, dental status, alveolar crest height, mandibular cortical index (MCI) with USG. Methods: A total of 120 MF and mental arteries of 60 patients (21 males and 39 females), including 20 patients in each group, aged 18-39, 40-59, and 60 years and above, were evaluated. The horizontal and vertical diameter of the MF and the distance between it and the alveolar crest were evaluated with USG and CBCT. In addition, mental artery blood flow parameters were examined by USG. Results: When the horizontal diameter values of MF were compared in USG and CBCT measurements; the diameter was significantly lower in the measurements obtained by USG (p 0.05). Conclusions: Considering that CBCT images are used as gold standard in our study, it may be said that USG is not as reliable as CBCT in evaluating the MF dimensions in the maxillofacial region. Nevertheless, USG is a suitable technique for determining the visualizing and blood flow of the MF

Reflexões sobre o gerenciamento do tempo na área de enfermagem
No full textTime is a valuable asset that must be used correctly and cautiously. Time management improves professional performance through analysis and planning. The health sector is one of the fastest undergoing changes and innovations around the world, so the health needs of individuals are increasingly varied and must be met quickly and efficiently. Health professionals, especially nurses, must keep up with these changes and strive to manage time in order to provide efficient and effective care. Staff nurses and nurse managers struggle to perform their various roles under the pressure of time. This article aimed to reflect on the importance of time management for nursing. It was determined that despite the notorious importance of time management for nursing, very little is done for nurses to develop knowledge and skills to better manage time. The nursing team can save time, extend the available time and avoid waste of time through efficient communication, adequate use of technologies, sufficient interaction with patients, division of labor, and knowledge of the routine of the unit. Administrators of health institutions and especially nurse managers should pay attention to the importance of training nursing professionals in time management. Therefore, nurse managers themselves must have the knowledge to better analyze situations and plan their tasks so that time is used effectively and efficiently. It is essential to use time correctly, because every second of life is part of a great fortune, and in the health field, a second can represent the difference that will save someone’s life
