Conference Object Citation Count: 0A case study on measuring course learning outcomes in software engineering education;(CEUR-WS, 2017) Karakaya,M.; Turhan,C.; Yazici,A.One of the most critical outcomes in the MÜDEK accreditation system which plays an important role in the evaluation and assessment of the quality of education in higher education institutions is evaluating how much students have achieved the course outcomes. This study aims to compare two methods utilized to measure course outcomes in the Software Engineering department of Atilim University. In the most general sense, these two methods are based on indirect and direct measurement techniques. The results of the analysis show a high degree of differentiation between the direct measurement and indirect measurement results. In light of the results obtained, some recommendations have been offered for course outcome assessment methods to be developed in the scope of MÜDEK accreditation.Conference Object Citation Count: 1Comfort based investigation on historic libraries for user satisfaction and preservation of paper-based collections(IOP Publishing Ltd, 2021) Turhan, Çiğdem; Topan,C.; Turhan, Cihan; Goksal Ozbalta,T.; Gok en Akkurt,G.; Software Engineering; Energy Systems EngineeringHistoric libraries preserve cultural heritage values while housing rare manuscripts and paper-based collections. The collections in the libraries are deteriorated chemically, biologically and mechanically due to inappropriate indoor environment conditions such as temperature and relative humidity fluctuations and microbiological conditions. Apart from preserving vulnerable paper-based collections, accommodating of a considerable thermal comfort level for visitors is essential in historic libraries. The aim of this study is to analyse indoor environment of a historic library in terms of thermal comfort and preventive conservation of paper-based collections. Izmir National Library, built in 1933, is selected as a case study. Indoor air temperature, relative humidity and air velocity in the library were monitored with a one-year measurement campaign. Meanwhile, thermal comfort of the visitors was assessed with PMV/PPD indices and thermal sensation surveys. The results show that high chemical degradation risk is detected in the library while biological and mechanical degradations are in the low risk zone. On the other hand, 87% and 93% of the visitors feel thermally satisfied in heating and cooling seasons, respectively. © Published under licence by IOP Publishing Ltd.Article Citation Count: 10A comprehensive assessment plan for accreditation in engineering education: A case study in Turkey(Tempus Publications, 2015) Turhan,C.; Sengul,G.; Koyuncu,M.This paper describes the procedure followed by Computer Engineering and Software Engineering programs at Atilim University, Ankara, Turkey, which led to the granting of five years of accreditation by MUDEK, the local accreditation body authorized by The European Network for Accreditation of Engineering Education (ENAEE) to award the EUR-ACElabel, and a full member signatory of Washington Accord of International Engineering Alliance(IEA).

Therefore, the importance of classification has increased to understand and analyze the data more easily, and this made emotion analysis a necessity. Research in this area shows that emotion is a key tool in analyzing texts. However, there are very limited studies conducted on the text in Turkish language. The purpose of this study is to detect emotions in Turkish texts by analyzing the results of earlier studies in this scope. The following research questions are aimed to be answered: What are the years and count of publications What are the techniques used in the emotion analysis on texts What are the main data sets Which types of emotion are detected Which tools are used in emotion analysis For this reason, a systematic mapping study is performed to categorize and summarize the existing literature on emotion analysis. To ensure relevant papers in this field, an automated search process is performed for this study. Web of Science and Scopus databases are used for searching current and past research in emotion analysis on texts. There are 66 articles found on this subject. Then, by using filtering, irrelevant studies are removed. According to a set of inclusion and exclusion criteria, 9 relevant papers are selected in this field. The machine learning method is used for text analysis that automatically identifies the patterns and makes decisions about emotions. © 2022 IEEE.Article Citation Count: 0Integration of social media into engineering education: A comparative study on perceptions of faculty and students(Tempus Publications, 2018) Turhan,C.; Akman,I.For a number of years, the effects of incorporating social media into education systems has invoked the interest of researchers, academicians and students. Yet, the enthusiasm of students in utilizing social media for learning is met with reluctance on the faculty's part in abandoning the traditional ways of teaching. This study compares the students' and faculty's acceptance of the utilization of social media in engineering education from different perspectives. A survey approach has been used for this purpose and 57 faculty and 85 students from the engineering faculties participated in the study. The research model used was tested using the least square regression technique. The results show existence of significant diversity between the faculty and students in the factors affecting the ethical usage. Concerning the general usage, this diversity exists in only the awareness. These results are expected to provide insight into the issues that act as barriers towards a more open, collaborative and learner-centered higher education platform. © 2018 TEMPUS Publications.Conference Object Citation Count: 0Investigation of the Relationship between Tension Level and Thermal Sensation. A Case Study of University Study Hall(EDP Sciences, 2023) Özbey, Mehmet Furkan; Alkan, Neşe; Turhan, Çiğdem; Turhan, Cihan; Mechanical Engineering; Department of Psychology; Software Engineering; Energy Systems EngineeringThe adaptive thermal comfort model steps forth against Fanger's Predicted Mean Vote/ Percentage of Dissatisfied model because of considering the psychological and behavioural adjustments in addition to environmental and personal parameters in mixed-mode and non-air-conditioned buildings. Among behavioural and psychological adjustments, human behaviour is more investigated than psychological adjustments in aspects of thermal sensation and comfort in the studies. To meet the deficit in the literature on how psychological adjustments affect thermal sensation, an experimental investigation was conducted to explore the effects of tension level on the Thermal Sensation Votes (TSV) of the students. Profile of Mood States (POMS) questionnaire was used to determine the tension level of the students. Experiments were conducted in a university study hall which is in the warm-summer Mediterranean climate (Csb) zone according to Köppen-Geiger Climate Classification. A total of 1159 students participated in the study, and the relation between the tension level and TSVs of the students were investigated for each gender. To test the associations between the nine quantitative subscales of tension level and the TSV, Pearson's correlation coefficient was computed. Based on results, "anxious"were considerable for the TSVs of both genders where the p-values were <0,001 for male and 0,044 for female students. In addition, while "shaky"(p=0,001) and "uneasy"(p<0,001) were found significant for the TSVs of male, "nervous"(p=0,013) were discovered noteworthy for the TSVs of the female students. © The Authors, published by EDP Sciences, 2023.Article Citation Count: 0Modeling the mood state on thermal sensation with a data mining algorithm and testing the accuracy of mood state correction factor(Elsevier Ltd, 2025) Yerlikaya-Özkurt,F.; Özbey,M.F.; Turhan,C.Psychology is proven as an influencing factor on thermal sensation. On the other hand, mood state is one of the significant parameters in psychology field. To this aim, in the literature, mood state correction factor on thermal sensation (Turhan and Özbey coefficients) is derived utilizing with data-driven black-box model. However, novel models which present analytical form of the mood state correction factor should be derived based on the several descriptive variables on thermal sensation. Moreover, the result of this factor should also be checked with analytical model results. Therefore, this study investigates the modelling of mood state correction factor with a data mining algorithm, called Multivariate Adaptive Regression Splines (MARS). Additionally, the mood state is also taken as a thermal sensation parameter besides environmental parameters in this algorithm. The same data, which are collected from a university study hall in a temperate climate zone, are used and the model results are compared with the thermal sensation results based on mood state correction factor which is driven via black-box model. The results show that coefficient of correlation “r” between the MARS and black-box model is found as 0.9426 and 0.9420 for training and testing. Hence, the mood state is also modelled via a data mining algorithm with a high accuracy, besides the black-box model. © 2024 Elsevier LtdArticle Citation Count: 3Online Learning Perceptions amid COVID-19 Pandemic: The Engineering Undergraduates' Perspective(Tempus Publications, 2022) Eryilmaz,M.; Kalem,G.; Kilic,H.; Tirkes,G.; Topalli,D.; Turhan,C.; Yazici,A.The COVID-19 pandemic caused face-to-face education in just about all universities worldwide to shift to online education. For most students, this educational model was a compulsory first experience. In this study, the survey results are analyzed and discussed related to a group of students in the Engineering Faculty of a university in Turkey regarding their online education perceptions. Briefly summarized, the findings of the study indicate that: (a) most of the students still prefer face-to-face learning, which is also favored if accompanied by distance learning; (b) the concentration level ol the students has dropped due to the concerns about the COVID-19 pandemic which affects their learning negatively; and (c) around half of the students participating in the study feel that the online exams conducted without a secure exam software, is considered unsafe. Additionally, the study's results were further extended to evaluate the questionnaire results an reported along with the suggestions of necessary actions in emergency online learning (EOL). © 2022 Tempus Publications.

Requirement analysis, which is one of the initial stages of the life cycle, can be considered as the most important stage of a project. Incorrectly defined, analyzed, and incorporated, requirements can lead to errors or even project failure in the later stages of the project. Considering the existence of software products in almost every field today, we can say that different requirements have arisen in a wide variety of fields. The use of appropriate technologies can yield much more efficient results than manual analysis of these relatively large numbers of different requirements. One of them is ontology-based approaches. In this research, the use of ontologies in software requirement analysis has been investigated. Systematic mapping was chosen as the research method. At the end of the study, it was found that technologies that adopt an ontology-based approach increase efficiency and accuracy in software requirements analysis. © 2022 IEEE.Conference Object Citation Count: 2Utilization of Online Collaborative Tools in Software Engineering: An Empirical Study on Review Meetings(Institute of Electrical and Electronics Engineers Inc., 2021) Turhan, Çiğdem; Turhan,C.; Turhan, Cihan; Hacaloğlu, Tuna; Software Engineering; Energy Systems Engineering; Information Systems EngineeringSoftware development involves a significant amount of team effort where collaboration and communication of the team members are crucial. The team meetings are core activities in all stages of the software development process. Even though these meetings often are conducted face-to-face (F2F) with a lackof technology utilization, changing global conditions such as the COVID-19 pandemic require other solutions urgently without interrupting the software development schedule. For this purpose, online collaborative tools provide new opportunities for software teams to work together avoiding waste in time and resources and the relevant literature is immature. This study aims to assess the factors affecting the integration of online collaborative tools to SE practices with a special reference to review meetings. For this purpose, a sample of 73 SE sophomore and junior students who are future software professionals participated in experimental review meetings based on predefined scenarios. The findings indicate that the utilization of OCT's has positive effects on the participants' actual performance and improves the interaction between team members compared to F2F meetings. © 2021 IEEE
