Derleme ve vaka çalışması

Yas süreci ve depresyon, Freud’un (1915/2000) Yas ve Melankoli üzerine makalesinden bu yana, birbiri ile ilişkili olarak değerlendirilmiş ve iki süreci ayrıştıran özellikler, kuramcılar ve klinisyenler tarafından ilgi odağı olmuştur. Son dönemde, komplike yas kavramı, araştırmalar temelinde, kendine özgü bazı belirtileri kapsayacak şekilde tanımlanmıştır. Literatürdeki yaygın ismi ile komplike yas, süreğen kompleks yas bozukluğu olarak DSM-V tanı kitabına dahil edilmiştir. Bu tanının DSM-V’e dahil edilmesi, gelecekteki çalışmaları arttırmak ve onlara yön vermek amacı taşımaktadır. Bu makalede, literatürdeki araştırmalara paralel olarak “komplike yas” kavramı kullanılmış; kaybın inkarı, ölen kişiye dair sürekli zihinsel meşguliyet, yoğun hasret ve kaybedilenle bir araya gelmek amacıyla intihar düşünceleri gibi belirtileri niteleyen bu kavramın, normal yas sürecinden farkına, komplike yasa yol açabilecek bazı faktörlere, komplike yasın bilişsel kavramsallaştırması ile bu temelde ilerleyen bir vaka çalışmasına yer verilmiştir.Publisher's Versio

Seismic Assessment of the Historical Sütlü Minaret Mosque

Historical masonry structures that connecting the past to the present have great importance because they represent the experiences and characteristics of various cultures. Therefore, the protection of historical structures is important. In this study, the structural response of the historical masonry Mosque was evaluated through dynamic analyses. For this purpose, the Sütlü Minaret Mosque which is located in Malatya, Turkey, was investigated. The three-dimensional model of the historical mosque was generated with ANSYS software. The material properties of the mosque were obtained with experimental tests. The time history analyses were used to obtain the seismic behavior of masonry mosque. In the time history analyses, six different strong ground motion records, including the 2020 Elazığ earthquake, were used. After the analysis, displacement and stress values in the mosque were given. The absolute peak displacement value among these earthquake records was obtained from the 1999 Düzce earthquake and the highest principal compressive and tensile stress values were determined for the 2010 Darfield earthquake. Also, the crack regions which occurred in the mosque after the 2020 Elazığ earthquake were compared with the dynamic analysis result of the 2020 Elazığ earthquake. The crack regions formed after the Elazığ earthquake are similar to the possible crack regions formed after the dynamic analysis

INVESTIGATION OF PREVENTIVE MEASURES TAKEN BY FACULTY OF DENTISTRY STUDENTS IN CLINICAL PRACTICES AND PERCEIVED STRESS LEVELS DURING THE EPIDEMIC PERIOD

Objectives: This study aimed to examine the prevention measures applied by dentistry students in clinical conditions according to various variables and their perceived stress levels during the COVID-19 epidemic. Methods: The study was performed on 4th and 5th -grade students studying at RTEU Faculty of Dentistry. In the research, the whole count method was used, and data were collected from 168 students through an online questionnaire. The questionnaire consisted of demographic information, questions about prevention measures taken in clinical practice, and perceived stress scale questions. Normality test (Shapiro-Wilk) was applied to the data and T-Test and Chi-Square Analysis were used for statistical analysis. Significance was determined as p≤0.05. Results: The perceived stress levels of female students were found to be significantly higher than that of male students, and the perceived stress levels of 5th-grade students were significantly higher than that of 4th-grade students. The perceived stress levels of the students who used rubber dams were found to be significantly lower than the students who did not use rubber dams and the students who paid attention to social distance in the clinic compared to those who did not pay attention to social distance. Moreover, the perceived stress levels of students who knew which institution to contact with a suspected COVID-19 patient were found to be significantly lower than those who did not know (p<0.05). Conclusion: It was determined that taking preventive measures in clinical practices was effective on students' perceived stress levels. Besides, it was observed that the perceived stress level of the students differed according to gender and grade level

A Study on the venom gland and the venom of the spider Alopecosa fabrilis (Clerck, 1757) (Araneae, Lycosidae)

Alopecosa fabrilis (Clerck, 1757) örümceğinin zehir bezinin morfolojik yapısı taramalı elektron mikroskobun (SEM)’da incelenmiştir. Prosomada yer alan zehir bezi bir çift olup silindir şeklindedir. Bezin tüp şeklinde bir gövde kısmı ve bununla bağlantılı bir kanaldan meydana geldiği görülmüştür. Bezin etrafı ise çizgili kas lifleri ile kuşatılmıştır. Zehir bezinde üretilen zehir gerek insanlar gerekse de diğer canlılar için toksiktir. Na+ ve Ca++ elementlerince zengin olduğu bulunmuştur. Bu analiz sonuçları zehir içeriğinin sinir ve kas sistemi üzerine etkili olduğunu göstermiştir. Anahtar Kelimeler: Alopecosa fabrilis, elementer analiz, taramalı elektron mikroskop (SEM), zehir bezi.The venom glands vary in shape and position. The size of the venom gland is not necessarily related to the size of the spider. In this study the morphological structure of the venom gland of the spider Alopecosa fabrilis (Clerck, 1757) was studied using scanning electron microscope (SEM). Alopecosa fabrilis has a small body, the size of its venom gland is rather large.  The venom gland situated at the prosoma has a pair and has cylindrical in shape. The glands were determined to be one lobed. and  observed to be composed of a stem part being similar to tube in shape and a channel connected with it. The dorsal surfaces of the glands are surrounded by numerous spirally arranged straite musculer fiber.When the spider bites,the venom fang moves out of the groove and penetrates the prey. At the same time, the venom is injected into the prey from a tiny opening at the tip of the venom fang. Venom is produced in a pair of venom glands situated in the interior portion of the prosoma. The venom produced in the venom gland is toxic for humans and other living things. However the spider venom is obtained for use in medical treatment of diseases such as cardiac disturbance and for production of new antibacterial reagent.  At elementary  analysis of the venom content, it was found to be rich for Na+ and Ca++ elements. These analysis results were demostrated that content of the venom has effective on nervous and muscular system. Keywords: Alopecosa fabrilis, elementarical analysis, scanning electron microscope (SEM), venom glands

Accuracy survey in photogrammetric data generation with unmanned aerial vehicles in mountainous, rough terrain: Example of Yusufeli Dam

İnsanların ulaşmakta güçlük çektiği eğimli, engebeli arazilerde insansız hava araçlarının (İHA) yardımı ve fotogrametrik yöntemlerle araziyi modellemek, diğer yöntemlere göre maliyet ve zaman açısından daha avantajlıdır. Bu çalışmada dağlık, engebeli arazilerde fotogrametrik modellemenin doğruluğu ve yer kontrol noktalarının (YKN) dağılımının konum doğruluğuna etkisi incelenmiştir. Bu kapsamda Artvin-Yusufeli barajı inşaat sahası çalışma bölgesi olarak seçilmiştir. Bölgeye YKN tesis edilmiş ve konumları yersel ölçme yöntemleri ile tayin edilerek uçuş aşamasına geçilmiştir. İHA ile elde edilen bindirmeli görüntülerle Pix4d yazılımında, YKN’lerin konumları baz alınarak koordinatlı üç boyutlu modeller oluşturulmuştur. İlk etapta YKN’ler, yatayda ve düşeyde homojen olarak dağıtılmış, daha sonra farklı yükseltilerde farklı dağılım biçimleri uygulanarak YKN’lerin konum doğruluğuna etkisi incelenmiştir. Sonuç olarak, yatayda ve düşeyde homojen YKN dağılımı ile maksimum hata miktarının 5 cm’nin altında olduğu görülmüş, çalışma bölgesinin sınırlarını yatayda ve düşeyde üç boyutlu olarak çevreleyen, arazinin topografik yapısını yansıtan bir YKN dağılımının gerekliliği açıkça ortaya konmuştur.Modeling the terrain with the help of photogrammetric methods and unmanned aerial vehicles (UAV) on sloping and uneven area where people have difficulty to enter is more advantageous than other methods in terms of cost and time consumed. In this study, the accuracy of photogrammetric modeling in mountainous and rough areas and the effect of the distribution of ground control points (YKN) on location accuracy were investigated. For this purpose, the Artvin-Yusufeli dam construction site has been selected as the study area. GCPs have been established in the region and their locations have been determined with local measurement methods and then the flight phase has been started. Coordinated three-dimensional models were created based on the location of the GCPs with overlap images obtained by UAV. It was done with the help of Pix4d software. In the first stage GCPs were distributed homogeneously in three dimensions, and then the effect of GCPs on position accuracy was examined by applying different distribution patterns at different elevations. As a result, with the use of homogeneous GCP distribution horizontally and vertically it has been discovered that the maximum error is less than 5 cm. It has been clearly demonstrated that GCP distribution should encompass the boundaries of the working area homogeneously in three dimensions horizontally and vertically representing the topography of the area

Triple X Syndrome with a Rare Finding: Cleft Palate

Triple X syndrome (trisomy X) is a sex chromosomal anomaly caused by the presence of an extra X chromosome. The patients with Triple X syndrome have a wide range of phenotypic variability. Some individuals are only mildly affected or asymptomatic. Epicanthal folds, clinodactyly, tall stature and hypotonia are the most commom phenotypic features. Patients also may have seizures, genitourinary abnormalities and premature ovarian failure. We report a patient with Triple X syndrome and cleft palate. By describing this case, we want to draw attention to the association between cleft palate and Triple X syndrome
