Determination of misconceptions in cooking methods and chopping techniques in culinary education
(Ebru Bagci, 2025) Sökmen, Cevdet; Sarıoğlan, Mehmet
This study aims to determine the misconceptions
that students enrolled in the culinary program have
regarding cooking methods and cutting techniques.
Within the scope of the research, a three-stage misconception determination test was administered to
first- and second-year students enrolled in the Culinary Program at Söğüt Vocational School. Concept
maps related to the subject were prepared for the
students before the test was administered. The test
results were analysed in terms of general misconceptions and positive and negative misconceptions.
The findings from the analysis of misconceptions
showed that students had the most misconceptions
about techniques such as “blanching”, “braising”
and “stir frying”. When examining the findings on
chopping techniques, the same results emerged for
the concepts of “paysanne chopping”, “medium
dice chopping” and “oblique cuts”. The high level
of confidence in the answers chosen by the students
indicates that the misconceptions are persistent.
The results indicate the need to develop educational strategies for concept teaching in culinary education.
Determination of phenolic content and antioxidant activity of Inula viscosa L. Aiton
(İzmir University of Democracy, 2025) Berber, Çiğdem; Kılıç, Turgut
The phenolic profile of three distinct extracts (petroleum ether (IVPE), acetone (IVA) and methanol (IVM)) derived from the aerial parts of the medicinal species Inula viscosa L. Aiton was determined using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS). In this study, the analysis of phenolic compounds in petroleum ether and acetone extracts and the total phenolic content (TPC) for I. viscosaspecies were reported for the first time. Based on the results, IVA extract was found to be the richest in phenolic content (3189.14 mg/kg) followed by IVM (2509.39 mg/kg) and IVPE (184.37 mg/kg). Rhamnocitrin, dihydrokaempferol, isosakuranetin, nepetin, nepetin-7-glucoside, acacetin, quercetin, verbascoside, and taxifolin were the most prevalent phenolic compounds; the IVA extract contained the highest concentrations of these. In summary, I. viscosa extracts demonstrate significant phenolic content and considerable antioxidant activity. Furthermore, the TPC of these extracts was quantified using the FolinCiocalteu reagent, with IVA showing the highest phenolic content value (440.4 ± 0.001mg GAE/g), followed by IVM (273.7 ± 0.001mg GAE/g), and the lowest value was determined in IVPE (51.8 ± 0.001 mg GAE/g). The antioxidant capacities of the extracts were assessed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the cupric ion (Cu²⁺) reducing capacity (CUPRAC) method. According to the DPPH results, IVA exhibited moderate-to-high radical scavenging activity at all concentrations and had the highest CUPRAC value (0.62±0.04), consistent with its elevated phenolic content. The results showed that I. viscosa extracts are rich in phenolic compounds and exhibit strong
antioxidant properties.
Mühendislik öğrencilerinin programlama öz-yeterlikleri algı düzeylerinin belirlenmesi ve öğrencilerin programlama hakkındaki görüşleri
(Çanakkale Onsekiz Mart University, 2025) Yavuz, Fırat; Karamete, Ayşen
Computer programming is a critical skill for engineering students, and self-efficacy in this domain directly influences their learning. This study examined engineering students' self-efficacy levels in computer programming and their opinions about the programming course. A mixed-methods approach was adopted in a study conducted at the Faculty of Engineering of a state university in Turkey during the 2022-2023 Spring Semester. Accordingly, two-stage data were collected, comprising quantitative data from 355 students and qualitative data from 12 students. The Computer Programming Self-Efficacy Scale and a semi-structured interview form were used as data collection tools. Findings indicated that students had a moderate overall level of self-efficacy (X=63.86). While cooperation and logical thinking dimensions had high scores, algorithm development scored relatively low. Gender did not significantly affect self-efficacy; however, department, computer ownership, and number of programming courses taken did. Qualitative findings emphasized the importance of algorithm design, debugging, and collaboration in developing self-efficacy. The study highlights the need to revise curricula to strengthen students' algorithmic thinking and practical skills in programming.
Solar energy for greenhouse drying: Performance evaluation of parabolic trough solar collector with two-axis tracking system
(Elsevier Ltd, 2025) Pektezel, Oğuzhan; Şimşek, Mithat; Daş, Mehmet
This study was conducted to develop a solution for the efficient and sustainable use of solar energy in food drying
in response to the depletion of fossil fuels, environmental concerns, and increasing energy demand. The moti
vation is to improve energy efficiency and provide environmentally friendly alternatives in food drying appli
cations. This study experimentally evaluated the performance of a greenhouse dryer equipped with a parabolic
trough solar collector (PTSC) with an air-fluidized, dual-axis solar tracking system (STS). The experiments were
conducted between June 12 and June 17, 2023, in Tokat, Turkey, located between 39◦51′–40◦55′ North latitudes
and 35◦27′–37◦39′ East longitudes, between 10:00 a.m. and 5:00p.m. each day. In the apple drying experiments,
solar radiation was continuously directed to the collector at an optimum angle with STS, and energy efficiency
and exergy efficiency increased by 28.7 % and 36.2 %, respectively. Drying time decreased by 57.2 %, and the
product surface temperature reached 76.1 ◦C. With the effect of STS, solar radiation on the system increased by
an average of 18.8 %, and drying efficiency improved by 47.2 %. The study’s originality is using air-fluid in the
tube system, which is equipped with a dual-axis, fully automatic solar tracking mechanism. In the literature,
water-based and single-axis systems have generally been studied. This study introduces an innovation that en
hances the efficiency and sustainability of solar energy usage in food drying. It offers a transformative approach
to integrating energy systems within agricultural practices, paving the way for a more effective and environ
mentally friendly future in food drying.
A study on subsequent expansions of the operators 𝑺(𝑨), algebraic sum, and geometric product over IVTNFSS
(American Scientific Publishing Group (ASPG), 2025) Rajesh, K.; Kausar, Nasreen; Kaviyarasu, M.; Koma, Behzad Omidi
In this work, subsequent expansions of the operators 𝑆(𝐴), algebraic sum and geometric product over IVTNFs.
The first of 𝑆(𝛼, 𝛽) is called the shrinking operator and the second, which is an extension of the first, is called
(𝛼, 𝛽) - shrink operator. The membership values & the values of non-membership be not completion our for all
time possible, although in the branch of IVTNFS, it plays an additional significant character at this time, since the
interval valued temporal neutrosophic fuzzy sets provides the best solution for finding the shortest distance in
deciding one's career, judgment making and image processing and many more areas. Especially in medical
diagnosis, when using this concept, there is a real chance that there will be a non-zero fraction of hesitation at any
point in the assessment.
