The popularization of artificial intelligence (AI) technologies has also begun to transform library services. In this research, a survey was conducted to determine the adjustments that university libraries in Turkey have made and plan to make during the development process of AI technologies and applications, and to identify the services they have developed specific to the relevant period. The survey was carried out with the participation of 111 university library managers from 208 university libraries in Turkey. Through the analysis of the data, the status, knowledge, and awareness levels of university libraries regarding AI technologies and applications were determined, and measures and recommendations were presented to improve deficiencies and weaknesses. This research is the first and most comprehensive study conducted in Turkey by obtaining opinions and suggestions from university library managers on artificial intelligence. The research findings revealed that university libraries use AI applications such as ChatGPT, Gemini, and Grammarly to a certain extent; however, they have needs in developing institutional policies, enhancing personnel competencies, and planning related to AI. © 2024 University and Research Librarians Association (UNAK).

İlin farklı bölgelerinde özellikle yoğun yerleşimin bulunduğu alanlarda, Selçuklu Dönemi’ne ait 12. ve 14. yüzyıllar arası yapılmış çok sayıda cami, kümbet ve medrese türü tarihi esere rastlamak mümkündür. Kültürel miras niteliğindeki bu eserler çoğunlukla yakın çevrede yoğun olarak bulunan farklı renk ve dokudaki ignimbirit türü kaya malzemesi kullanılarak inşa edilmişlerdir. Genel olarak düşük dayanıma sahip ve su etkilerine karşı hassas olan bu ignimbiritler zaman içerisinde atmosferik etkenler, hava kirliği, vandalizm vb. gibi olaylar sonucunda bozunmakta ve ilksel özelliklerini kaybetmektedirler. Bu çalışmada Kayseri il merkezindeki Roma ve Selçuklu dönemlerine ait tarihi eserler ile bu eserlerde zaman içinde meydana gelen bozunma etkileri incelenmiştir. Bozunma etkilerinin gözlemsel olarak incelenmesinin yanı sıra, eserlere herhangi bir zararı bulunmayan tahribatsız deney yöntemlerinden İğne Penetrometresi, Schmidt Çekici ve P-dalga hızı deneylerinden faydalanılmıştır. Bunun yanı sıra, bozunmuş ignimbirit bloklarına ait yerinde deneylerle belirlenen değerler, aynı malzemeye ait taze örneklerin fiziko-mekanik özellikleri ile karşılaştırılmıştır. Yapılan değerlendirmeler sonucunda tarihi eserlerin taban bölümlerinde özellikle kılcallık sebebiyle pullanma ve kavlaklanma türü bozunmaların geliştiği ve ignimbiritlerin bu bölümlerde dayanımlarını önemli ölçüde kaybettiği tespit edilmiştir. İncelenen kümbetlerin bazılarına uygulanan iyileştirme çalışmalarında ise kümbetlerin çevresinde bulunan yüzey suyu drenajlarının yeterli ölçüde yapılamadığı ve yağmur ile biriken suların tarihi eserlerin daha fazla bozunmasına sebep olduğu saptanmıştır. Kültürel miras olarak değerlendirilen bu tarihi yapıların korunup gelecek nesillere aktarılması amacıyla, ignimbirit yapılarının yüzeysularına karşı duyarlılığı dikkate alınarak tarihi kümbetlerin çevresinde su drenajı iyileştirme çalışmaları yapılması önerilmektedir.Article Atatürk’ün Esir Aldığı Yunan General Nikolaos Trikupis ve Talas Üsera Garnizonu(Sabit Dokuyan, 2023-06-26) Karataş, Murat; Metin, MehmetAfter the First World War, especially with the support of England, the Greek army invaded Anatolian lands on the way to realize Megali Idea (Greater Greece). The regular army of the Turkish Grand National Assembly established on the Western Front dealt the final blow to the Greek army with The Great Offensive and the Battle of the Commander –in-Chief. In addition to the Greek soldiers captured in the wars before this victory, many Greek soldiers, as well as the commander –in-chief of the Greek army, General Trikupis, and her entourage were also captured after the said victory. As the number of prisoners increased rapidly after The Great Offensive and the Battle of the Commander –in-Chief, the captive officers were transferred to Afyon, Kırşehir and Kayseri. Other military and civilian prisoners were transferred to different parts of Anatolia. Greek prisoners of war were kept in the prisoner garrisons until the implementation of the document on the mutual release of prisoners signed between the states of Turkey and Greece at the Lausanne Peace Conference. Only Greek Officers remained in Talas Prisoner Garrison, one of these prisoner garrisons. The Talas Prisoner Garrison was inspected twice by international Committee of the Red Cross. The delegation prepared reports on the condition of the prisoners and the garrison. In this study, the captivity of General Trikupis on the battlefield, the Talas Prisoner Garrison and situation of the captive Greek officers staying here, the aid of the Red Crescent Society to the prisoners will be emphasized. The Study was planned to be prepared by making use archival resources, memoirs, newspapers and copyright-reviewed works. © 2023 Elsevier B.V., All rights reserved.Article Citation - Scopus: 10Kaya Tutma Hendek Performansının 3-Boyutlu Kaya Düşme Analizleriyle Değerlendirilmesi: Akköy (Ürgüp) Örneği(TMMOB - Jeoloji Muhendisleri Odasi jmo@jmo.org.tr, 2019-12-15) Akin, Mutluhan; Dinçer, İsmail; Orhan, Ahmet H.; Ok, Ali Özgün; Akin, Muge K.; Topal, TamerRockfall ditches or areas can be constructed in order to protect against rockfalls in settlements that are in danger of rockfalls when the population density is not high. Nevertheless, in the design of such protection structures, essential site-specific engineering studies and analyzes are often not carried out appropriately. Therefore, rockfallditches are occasionally not capable of preventing rockfalls. Within the scope of this study, the performance of a 2 m-deep and 1 km-long rockfall ditch excavated at the upper elevation of touristic Akköy (Ürgüp) settlement in 2012 in order to prevent the entrance of falling rocks to the residential area was evaluated on the basis of 3-dimensional rockfall analyses. According to the rockfall risk classification, the settlement is under moderate rockfall risk. The digital surface model used in 3-dimensional rockfall analyses was generated by point cloud data obtained from photogrammetric images taken by unmanned aerial vehicle. During field observations, it was determined that the dimension of the previously fallen ignimbrite blocks could reach up to 2 m. On the other hand, the high persistency of discontinuities in the source zone indicates that the dimensions of the potential rockfall blocks may be large. As a result of the 3-dimensional rockfall analyses carried out in RocPro3D software, it was defined that the falling blocks are generally caught by the ditch excavated between the source zone and the settlement, but in some sections of the ditch those blocks may continue to roll over the rockfall ditch. Eventually, Akköy settlement is still partially under the danger of rockfalls. If the rockfall ditch is not periodically cleaned in the course of time, the extent of danger will enlarge with the decrease in the capacity of the trench. © 2020 Elsevier B.V., All rights reserved.Article Citation - Scopus: 1Düzce Kent Merkezi Zeminlerinin Sıvılaşma Potansiyelinin Değerlendirilmesi(TMMOB - Jeoloji Muhendisleri Odasi jmo@jmo.org.tr, 2019-06-15) Akin, Muge K.Soil liquefaction is one of the ground deformations occurred during an earthquake which may cause serious damages such as settlement and tilting of structures due to loss of bearing capacity of foundations. Düzce and its surrounding settle on a plain which consists of silty and sandy layers with shallow groundwater level. Besides, the North Anatolian Fault Zone is a major seismic source which is capable of producing large magnitude earthquakes. All these data point out that the ground deformations like liquefaction and lateral spreading may occur during a probable large earthquake around Düzce and its close vicinity. In this study, the geotechnical data of 40 boreholes drilled to determine the local ground conditions and the groundwater level in Düzce were considered. Based on the field studies, it was aimed to evaluate the liquefaction potential considering the fact that the groundwater level is shallow as well as the subsurface soil is composed of loose alluvium. Liquefaction Potential Index (LPI) and Liquefaction Severity Index (LSI) methods were taken into account and the liquefaction potential of Düzce province was determined and mapped with respect to various earthquake scenarios in GIS environment. These maps are compared on the basis of different scenarios. Accordingly, it is concluded that the liquefaction potential is high-very high in the south and south-eastern sections of the study area where the construction of new residential buildings progressively continues. © 2019 Elsevier B.V., All rights reserved.Article Manganzı Demir Cevherinden Manganın Çözündürülmesinde Farklı İndirgeme Maddelerinin Etkisi(Chamber of Mining Engineers of Turkey, 2022-06-26) Top, S.; Altiner, Mahmut; Kursunoglu, SaitIIn this paper, the manganese extraction from a manganiferous iron ore was investigated using reductive leaching. Various chemicals were used as a reducing agent to leach manganese selectively from the ore in the presence of sulfuric acid (H2SO4) solution. Firstly, optimum dissolution values were determined for selective manganese dissolution without using a reducing agent. As it was aimed at the selective extraction of manganese from the ore, the reductive leaching tests were conducted by adding the reducing agents under the following optimal parameters: a leaching time of 1 h, a stirring speed of 300 rpm, a temperature of 70°C, a sulfuric acid concentration of 1 M where the ore was leached with an extraction ratio of 11.54% Mn and 2.16% Fe. Manganese was dissolved with high efficiencies (up to 97.46%) from the ore by using different organic compounds (tartaric acid (C<inf>4</inf>H<inf>6</inf>O<inf>6</inf>), oxalic acid (C<inf>2</inf>H<inf>2</inf>O<inf>4</inf>), citric acid (C<inf>6</inf>H<inf>8</inf>O<inf>7</inf>), glucose (C<inf>6</inf>H<inf>12</inf>O<inf>6</inf>), sucrose (C<inf>12</inf>H<inf>22</inf>O<inf>11</inf>), and maleic acid (C<inf>4</inf>H<inf>4</inf>O<inf>4</inf>)) as the reducing agents. © 2022 Elsevier B.V., All rights reserved.Article Citation - Scopus: 2Kalsitik ve Dolomitik Kireçtaşlarının Çimentolu Macun Dolgunun Çevresel Davranışına Etkisi(Chamber of Mining Engineers of Turkey, 2022-03-07) Yılmaz, Tekin; Ercikdi, BayramTo enhance the strength and stability of cemented paste backfill (CPB), many alkaline materials are utilised as replacement or additive to binder or tailings in CPB. However, the effect of these materials on groundwater pollution of CPB needs to be comprehensively investigated. In this study, effects of the utilization of calcitic and dolomitic limestone (CL and DL) as replacement (10 wt.%) to sulphide mine tailings (S-MT) in CPB mixture on the long-term environmental behaviour of CPB were investigated. For this purpose, CPB samples (CPBs) were subjected to dynamic tank leaching tests over 360-days and the analyses of pH, sulphate (SO4 2-) and heavy metals (HMs) on the leachates were carried out. The effects of mineralogy and microstructure on the environmental behavior of CPBs were also examined by X-ray diffractometry and porosity tests. The findings showed that with the utilization of CL and DL, the pH of leachates remained at alkaline levels and the release of SO4 2- was significantly reduced. Furthermore, the denser microstructure in CPBs of CL and DL contributed to be prevented or be remarkably reduced the HMs-releases (except Cu, Mo and Pb). The results reveal that the mechanical properties of CPB as well as its impact on the groundwater pollution should be carefully evaluated. © 2022 Elsevier B.V., All rights reserved.Article An Opportunity for Nuri Demirağ the National Development Party the Transition to Multiparty Life in Turkey(Osman Kose, 2023) Karatas, Murat; Solak, YeterThe political life in Turkey during the period of 1923-1945 showed a single-party characteristic. Turkey, which did not enter the Second World War in 1939-1945, faced some negativities brought by the war both during and after the war. These negativities have had a compelling effect on the government to switch to a multi-party system with the effect of external and internal factors. Nuri Demira & gbreve; founded the National Development Party while he was preparing to take a step towards a multiparty system in Turkey, forced by both domestic and foreign conditions. Although the party could not show an active presence in our political life, its establishment made an important contribution to the establishment of democracy culture and the Despite all the efforts of Nuri Demira & gbreve; as the founder and chairman of the party, the inconsistency in the party and the evaluation of party activities from the wrong points led to the party's indifference in political life. In 1957, the existence of the National Development Party in our political life came to an end quietly due to the fact that the party committee could not convene after the death of the party chairman, Nuri Demira & gbreve;.In this sense, our study aims to contribute to the literature by aiming to discuss the political adventure of the National Development Party, which stands at an important point in terms of the democratization process in our political life, and to reveal the role of its founder, Nuri Demirag, in this process.Article Citation - Scopus: 4Türkiye’de Yapılan Kuraklık Analiz Çalışmaları Üzerine Bir Derleme(Ankara University, 2022-10-31) Deniz Öztürk, Yasemin; Ünlü, Ramazan; Öztürk, Yasemin DenizDrought has become one of the most studied disaster issues by scientists, especially after the 2000s, with the importance of climate change. Many scientific publications on drought have been produced, due to many different methods on drought and the study of drought by many disciplines of science. In the study, theses, national and international articles, which include drought analysis by using any statistical method over meteorological data in Turkey, were compiled. A total of 270 studies, including 73 master's and Ph.D. theses, 107 national articles, and 90 international articles, written between 1943-2021 were examined. These studies were classified according to the year of publication, the drought analysis methods used, in publication, the scientific field of the first author, and the region examined in the study, and their frequency distributions were revealed. The main conclusions of this study are as follows: Although the first published studies on drought analysis in Turkey were made in 1943, 1956, and 1965, studies on drought started to increase after 2000 and the total number of publications reached 37 in 2019, 43 in 2020, and 64 in 2021. Publications in the period of 2019-2021 correspond to 53% of all publications. This rapid increase in recent years has led to a logarithmic increase in the number of publications. Although 63 different methods are used in drought analysis in the studies, the standardized precipitation index is the dominant method with a usage rate of 56%. Most of the studies were carried out on the basins (113). In 41 studies, the whole of Turkey was examined. Other studies were carried out for geographical regions, provinces, and smaller settlements. According to the scientific fields, it is seen that the Civil Engineering (131 units) and Geography (41 units) departments are the scientific fields that carry out the most drought analysis studies. © 2025 Elsevier B.V., All rights reserved.
