EAF Ladle Steel Slag as a Geo-Material: Compaction and Shear Strength Characteristics
No full textİrem Zeynep Yıldırım (MEF Author)##nofulltext##The numerous issues associated with the excess steel slag that is disposed of in landfills every year can be reduced by using it as a geo-material. This paper provides the results of laboratory tests (i.e., sieve, hydrometer, specific gravity, compaction, compaction-particle degradation, and large-scale direct shear with a box size of 30.5 x 30.5 x 20 cm) performed on electric-arc-furnace ladle [EAF(L)] steel slag from a mini-mill in Indiana. Based on standard proctor test results, the maximum dry unit weight values of the EAF(L) steel slag were in the 16.8-to-20 kN/m(3) range at the optimum moisture contents of 11-13%. The results of the large-scale direct shear tests performed on EAF(L) steel slag, compacted at 95-100% relative compaction and sheared with normal stress ranging from 50 to 300 kPa, showed that it has excellent frictional characteristics, with friction angles between 40 and 45 degrees. Based on the results from this study, due to its shear strength characteristics, EAF(L) steel slag has the potential to be utilized as a geo-material to improve the shear strength of various marginal soils.WOS:0004370007000122-s2.0-85048741251Conference Proceedings Citation Index- ScienceProceedings PaperMartYÖK - 2017-1

Abstract
The COVID-19 pandemic outbreak has dramatically worsened people’s psychological well-being. Our aim was to examine for the first time the concurrent and longitudinal relations of family resilience with hedonic and eudaimonic well-being, and the moderating role of socio-demographics. For people having a romantic partner, we also explored whether family resilience and dyadic coping were uniquely related to well-being. One cross-sectional study (N = 325) and one 10-week follow-up study (N = 112) were carried out during the outbreak of the COVID-19 pandemic (April–May 2020) in Northern Italy. Adult participants completed an online questionnaire in both studies. Correlation, multivariate regression, and moderation analyses were carried out with IBM SPSS version 28 and its PROCESS macro. Significance of differences in correlation and regression coefficients was tested through Steiger’s procedure, Wald test, and SUEST method. Family resilience was found to relate more strongly to eudaimonic (versus hedonic) well-being concurrently and to hedonic (versus eudaimonic) well-being longitudinally. The concurrent or longitudinal relations with hedonic well-being were generally stronger for females, part-time workers, and people undergoing multiple stressors. For people having a romantic partner, family resilience was concurrently associated with well-being independently of dyadic coping, whereas dyadic coping was longitudinally related to well-being independently of family resilience. Family resilience was found to protect, in the short term, the psychological well-being of people facing the pandemic outbreak. Its protective role mainly concerned hedonic well-being and was more pronounced for more vulnerable people. For persons having a romantic partner, however, dyadic coping seemed to have equal, if not greater, positive short-term effects

In the research, firstly, the national and international theoretical framework and studies regarding the concepts that make up the variables were examined. Then, the survey technique was used on the subject. In the questionnaire used, the opinions of academicians and teachers on data literacy were taken. From these opinions, ideas were taken while creating the article pool. There are 30 substances in the first process in the created item pool. With the receipt of expert opinions, it was decided to remove 3 items from the scale. The sample group of the research consists of 1200 primary school 4th grade students in Afyonkarahisar central schools. This sample group was selected by stratified sampling method. The first application of the scale, which consists of 27 items, was applied to 600 students and as a result of the exploratory factor analysis, it was decided to keep 17 items in the scale. Data were collected from 600 students in order to perform the confirmatory factor analysis of this new draft scale consisting of 17 items. It was decided not to remove any article in the DFA. When the model fit indices were examined, it was determined that χ 2 /sd, RMSEA, GFI, SRMR, NFI and NNFI values showed acceptable fit, and AGFI and CFI values showed perfect fit. In order to increase the reliability of the study and to learn the distinctiveness of the items, Cronbach's Alpha coefficients, Total item correlations and t and p values of the 27% lower and upper group were calculated. As a result of the analysis, it was concluded that the Data Literacy Scale for Primary School 4th Grade Students, which consists of 17 items, is valid and reliable. When the levels of the sample group belonging to the developed scale were examined, the mean of the scale was calculated as 80, 3517 and it was concluded that the sample group level was at a moderate level
The Traces of Feminism in Essays of Elif Şafak
No full textBu çalışmamızda, Elif Şafak’ın gazete ve dergilerde yayınlanan deneme yazılarını
derlediği dört deneme kitabı, sabit karşılaştırmalı analiz ve söylem analizi yöntemleriyle
incelenerek, bu kitaplarda yer alan yazılardaki kadın-erkek, kadın-kadın ikili karşıtlıkları,
yazarın kadına özgün bakış açısı ve bu bakış açısında yazarın feminist söylemleriyle
çelişen ifadeler olup olmadığı, yazarın egemen ataerkil söylemin yeniden üretilmesine
katkıda bulunup bulunmadığı tespit edilmeye çalışılmıştır.
Sabit karşılaştırmalı analiz yöntemiyle, dört kitap taranmış ve çalışmamıza uygun
olabilecek, tekrar gösteren temalar çerçevesinde metin örnekleri seçilmiş, bu örnekler,
gruplara ayrılarak, yukarıda adı geçen başlıklara ve temalara hizmet edip etmediği,
mevcut teoriler baz alınarak saptanmaya çalışılmış ve eleştirel söylem analizi yöntemi ile
değerlendirilmiştir.
Feminizmin elbette ki tek bir görüşü ya da algısı bulunmamaktadır. Bu konuda üretilmiş
sayısız teori mevcuttur. Bu çalışmada özellikle feminizmin çıkış noktası olarak ele alınan
ikili karşıtlıklar/ikilikler baz alınmıştır. Diğer temalar da ikili karşıtlıklar/ikilikler
üzerinden, yeni karşıtlıklar kümeleri yaratılıp yaratılmadığı, mevcut kümelerin beslenip
beslenilmediği dikkate alınarak şekillendirilmiştir. Sonuçta Şafak’ın kadın erkek ikili
karşıtlıklar kümesine hizmet eden, ataerkil söylemi yeniden üreten, kendi içerisinde yeni
kadınlık kümeleri ya da stereotipler yaratan ve bir kümeyi diğerine ötekileştiren
açıklamaları, karşılaştırmalı örneklerle tespit edilmiştir.In this body of work, four books by Elif Şafak containing her essays published in
various newspapers and magazines are discussed constant comparative analysis and
discourse analysis to derive binary oppositions in male-female & female-female
relationships, the female-centered perspective of the author and consecutive feminist
approach to identify if her point of view conflicts with the feminist rhetoric or
contributes to the reproduction of the dominant patriarchal discourse.
The four books have been dealt with using constant comparative analysis and relevant
repeating themes have been selected and categorized to compare with existing theories,
identify if they serve the feminist discourse and analyze in relation to the topics
mentioned above in the light of critical discourse analysis.
Feminism supersedes any single perspective or perception. A limitless number of
theories have been constructed in this subject. This analysis focuses on binary
oppositions/dualities as a starting point. The rest of the themes have been developed
considering binary oppositions/dualities, whether they reproduce new sets of
oppositions or nurture existing sets of discourse. As a conclusion, examples in Şafak’s
bibliography which complement the set of male-female binary oppositions, reproduce
the patriarchal discourse, produce new sets or stereotypes of femininity or otherize one
set to another have been identified with comparative examples
Gaziantep O?uzeli-Dokuzyol village reuse proposal; Example of Ezogelin Barak culture center
No full textDokuzyol village is a settlement 17 km away from Gaziantep Oǧuzeli district, within the Barak Plain boundaries. The old name of this village is Uruş; it is also known as Ezo Gelin's village because it is the birthplace of the legendary Ezo Gelin in folklore. There are traditional abode buildings in the village, but some have been abandoned, and village people have started to prefer reinforced concrete structures. Rural architecture is an embodiment of cultural heritage; therefore, preserving and transferring it to future generations is an essential cultural continuity element. The main reason for choosing this village is that there are examples of traditional abode architecture. To maintain the Barak Culture, an abode cultural center named Ezo Gelin was built in 2018. Cultural center seldom is used and haven't served its main purpose. The aim of this research is develop a renovation for Ezo Gelin Barak Culture Center, which was built with great investment but not used and to draw attention the abode building in the village. In this research adobe buildings of Dokuzyol village were documented with traditional method and function suggestions for the protection of buildings have been developed within scope of the Interior Architecture education survey course. It has been suggested that some of the unused abode buildings in the village to serve for the new function of Ezo Gelin Barak Culture Center. The proposal developed for Ezo Gelin Barak Cultural Center aims to contribute to rural tourism and cultural heritage. © 2022 Author(s)
Evaluating distance education performance within the scope of architectural education
No full textTurkey is affected by the COVID-19 pandemic widely as well as all around the world. There is also a global impact in the field of education. Several precautions were taken for preventing infection from COVID-19 at a minimal level. One of the taken precautions is launching a distance education system (DES). DES started to practice from primary to higher education easily and swiftly. This system is an alternative to the existing education system. However, universities' architecture departments that have theoretical courses besides applied courses, are known that they are hard to put to set, moreover, most of them hesitate to start distance education due to characteristics of architectural education. Architectural education teaches codifying phenomenon, concepts, thoughts visually with the help of symbols and teach to analyse these codes. This tenet involves different processes from a student's former education life. Therefore, to reach the aims of architectural education features' and actualization level of learning is essential. Professional schools give privileged status to systemic, preferably scientific knowledge, and the schools' prevailing epistemology of practice, treats professional competence as the application ok privileged knowledge to instrumental problems of practice. When architectural education is considered as a process to gain essential skills, it can be seen that how active learning is important. It does not seem possible to perform "active learning"requirements with the distance education system's existing opportunities and architecture students will perform "passive learning"during DES is thought. This study focuses on how DES is made productive for architectural education which started to use due to the COVID-19 pandemic. The main aim of this research is to determine problems of architecture students and instructors related to distance architecture education and offering solutions. Additionally, this research goals to contribute to the limited distance architecture education system. To reach these aims questionnaire forms were constituted toward interviews with both architecture students and instructors and from the literature review. Questionnaires were prepared separately for students and lecturers. This procedure aims to offer an integrated solution by gathering different perspectives of participants. Data of the project were acquired by applying online questionnaires to participants via e-mail. Obtained data were analysed statistically using SPSS 22.0 software. This research will make a remarkable contribution about how active learning at applied courses can be increased during DES at architectural schools by presenting qualitative and quantitative findings. © 2022 Author(s)
Self‐Regulation: Relations with Theory of Mind and Social Behaviour
No full textHarma, Mehmet/0000-0002-3955-1526; Korucu, Irem/0000-0001-7185-2284It is argued that self-regulation skill is necessary both for displaying constructive behaviour and for controlling negative social behaviour, and self-regulation might affect social behaviours by increasing the ability to understand others' minds. In this research, in order to examine different aspects of self-regulation and their similarities and differences in terms of their relations with other constructs, we focused on both effortful control and executive function and investigated their concurrent associations with socially competent and aggressive behaviours and theory of mind (ToM). The participants were 212 preschool children in Turkey. We assessed executive functions with behavioural measures and effortful control with mother reports. We used six tasks for comprehensive assessment of mental state understanding. Children's social competency and aggressive behaviour were assessed with teacher reports. Structural equation modelling results showed that when age and receptive language were controlled, ToM was significantly associated with social competence but not aggressive behaviour. Both effortful control and executive functions were significantly related to social competency and ToM; the pathways from each self-regulation skill were similar in strength. ToM was linked with social competence, but it did not have a mediating role in the relations of self-regulation with social competence. The findings highlighted the importance of self-regulation for socio-cognitive and social development in the preschool years.
