Middle School Fifth-Grade Students' Level of Understanding the Concept of Condensation in Different Contexts
No full textEvaporation, condensation, and boiling are fundamental concepts taught in science and chemistry classes, closely linked to daily life. These concepts are vital for students to grasp the transformation and conservation of matter, the particulate nature of matter, and related principles. This study evaluated fifth-grade students' comprehension of condensation across various contexts. The research involved 80 male and 59 female students from a public school in a qualitative phenomenological study. Data analysis utilized the content analysis method. As a result of the study, it was revealed that the students who participated in the research did not understand the concept of condensation sufficiently and could not explain this concept at the desired level in different contexts. Based on the findings, incorporating real-life contexts when teaching the concept of condensation can enhance the understanding of the topic. Moreover, it highlights the significance of an investigative approach to learning new concepts.The authors did not receive support from any organization for the submitted work
Relación entre la conciencia de madres y padres sobre el abuso sexual y las habilidades de los niños para decir «no»
No full textIntroduction: Child sexual abuse is a global and multidimensional social problem and causes devastating and permanent psychological, emotional, cognitive, behavioural, physical, sexual and interpersonal sequelae. This study examines the relationship between the ability to say > and parental awareness of sexual abuse in 4th grade primary school students. Methods: The study was conducted between April 2022 and June 2022 in primary schools in the central district of a province in north-eastern Turkey. The sample consisted of 310 students enrolled in 4th grade and their parents. We collected the data through a personal information form, the ability to say > scale for children and the sexual abuse awareness scale for parents. Results: There was a weak positive correlation between the mean maternal scores of sexual abuse awareness and the mean scores of refusal and resistance in children (P < .05), as well as a weak positive correlation between the mean paternal scores of sexual abuse awareness and the mean scores of refusal and resistance in children (P < .05). Conclusion: As mothers' and fathers' awareness of sexual abuse myths and of teachings and actions to combat sexual abuse increased, the refusal of children also increased. Also, as fathers' awareness of the signs of sexual abuse increased, children's refusal increased. (c) 2024 Asociaci & oacute;n Espa & ntilde;ola de Pediatr & iacute;a.

Global attractors in a two-species chemotaxis system with two chemicals and variable logistic sources
No full textThis paper deals with the higher dimension quasilinear parabolic-parabolic chemotaxis model involving a source term of logistic type (formula presented), subject to the homogeneous Neumann boundary conditions in a ? ? RN (N ? 1) with smooth boundary. It is shown that for the attractionrepulsion case with ?2 ? 0, the global boundedness of solutions can be ensured by µ1, µ2 > 0 without any other assumptions, due to the contribution of the logistic sources included in addition to the repulsion mechanism. While for the attraction-attraction case with ?2 > 0, the global boundedness of solutions has to require logistic coefficients µ1, µ2 > 0 such that µ2 properly large. © 2024, Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan.

Siyasal katılma farklı düzeylerde ve farklı biçimlerde ortaya çıkmaktadır. Birey, hangi dünya görüşüne sahip olursa olsun siyaset karşısında bir tavır takınmaktadır. Çeşitli gerekçelerle siyasete katılmaktadır. Siyasal katılma, bireyin sahip olduğu bilinç düzeyinden ülkenin sahip olduğu yönetim anlayışına kadar birçok hususla yakından ilgilidir. Farklı siyasal kültüre sahip toplumlarda doğal olarak farklı siyasal katılma pratikleri gerçekleşmektedir. Bu çalışmada siyasal katılma düzeyleri konu edinilmiştir. Bu kapsamda İzmir ile Bayburt illerinin siyasal katılma düzeyleri karşılaştırılmıştır. Çalışmada nicel araştırma yöntemi uygulanmış, 807 kişi araştırmaya dahil edilmiştir. Verilerin toplanmasında demografik bilgi formu ve demokratik katılım ölçeğinin siyasal katılım boyutu kullanılmıştır. Veriler SPSS 25.00 paket programı ile analiz edilmiştir. Tanımlayıcı sonuçlar incelendiğinde hizmet ve politika takibi (3.62 = yüksek), siyasi tartışma (2.78 = orta), toplam siyasal katılım puanı (2.30 = düşük), seçim mitingleri (1.61 = çok düşük), gösteri ve yürüyüşler (1.52 = çok düşük) ve düşünce ve önerileri paylaşma (1.48 = çok düşük) olacak şekilde siyasal katılımın alt boyutlarından alınan puanların çok yüksek olmadığı, siyasal katılımın birçok boyutta çok düşük kaldığı belirlenmiştir. İzmir ve Bayburt ilinde yaşayan katılımcıların siyasal katılım düzeyleri karşılaştırıldığında tüm alt boyutlarda ve toplam siyasal katılımda İzmir ilinin lehine anlamlı bir farklılık belirlenmiştir. Çalışma sonucunda ilerleyen çalışmaların siyasal katılımı düşüren değişkenlere daha derinlemesine araştırması önerilmektedir. Ayrıca siyasal katılımı artırıcı faktörlerin belirlenip bu konuda politikalar geliştirilmesi de önemli görülmektedir.Political participation is the actions taken by individuals to determine and influence the political sphere. Political participation occurs at different levels and in different forms. Regardless of the worldview the individual has, he/she takes a stance against politics. He participates in politics for various reasons. Political participation is closely related to many issues, from the level of consciousness of the individual to the management approach of the country. Naturally, different political participation practices occur in societies with different political cultures. In this study, political participation levels are discussed. In this context, the political participation levels of Izmir and Bayburt provinces were compared. Quantitative research method was applied in the study and 807 people were included in the study. A demographic information form and the political participation dimension of the democratic participation scale were used to collect data. The data were analyzed with the SPSS 25.00 package program. When the descriptive results are examined, service and policy following (3.62 = high), political debate (2.78 = medium), total political participation score (2.30 = low), election rallies (1.61 = very low), demonstrations and marches (1.52 = very low) and It was determined that the scores obtained from the sub-dimensions of political participation, such as sharing thoughts and suggestions (1.48 = very low), were not very high, and political participation remained very low in many dimensions. When the political participation levels of the participants living in Izmir and Bayburt were compared, a significant difference was determined in favor of Izmir in all sub-dimensions and total political participation. As a result of the study, it is recommended that future studies investigate more deeply the variables that reduce political participation. It is also considered important to identify factors that increase political participation and develop policies on this issue
Ultrasound-assisted deep eutectic solvent extraction of bioactive compounds from persimmon calyx
No full textThis study aimed to investigate the ultrasound-assisted extraction of bioactive compounds from persimmon (Diospyros kaki) calyx by deep eutectic solvents (DES) with different molar ratios. For this reason, the prepared DES extracts' total phenolic-flavonoid compounds and antioxidant activities (1,1-diphenyl-2-picrilhydrazyl radical scavenging activity [DPPH center dot], Cupric Reducing Antioxidant Capacity (CUPRAC), and ferric reducing antioxidant power [FRAP]) were investigated as a result of the experimental design and optimization study conducted for this purpose. A sonication time of 20 min was determined as the optimal condition. Under these conditions, a molar ratio of 1.9:1 (lactic acid:choline chloride) and a water ratio of 70% provided the highest phenolic/flavonoid compounds and antioxidative activity. Correlations among water ratio, molar ratio, and sonication time were determined using principal component analysis (PCA). In conditions where total flavonoid compound, FRAP, and DPPH center dot are high due to PCA, it can be concluded that the sonication time is at high level; on the contrary, the water and molar ratios are at low level. In conclusion, ultrasound-assisted extraction using DES proved effective in persimmon calyx. Therefore, it can be recommended to use these environmentally friendly green solvents as an alternative to organic solvents in preparing extracts in various fields. Practical Application: This study shows the effectiveness of the ultrasound-assisted green extraction method using persimmon calyx specified as waste. These findings are compelling in the food industry in terms of consumers being now aware of green technology and the discovery that calyx is a good source of bioactive compounds

No full text3rd International Conference on Research of Agricultural and Food Technologies, I-CRAFT 2023 -- 4 October 2023 through 6 October 2023 -- Adana -- 196444Energy in agriculture and in food production have vital importance that affect directly the cost and the quality of the products. Micro cogeneration plants are widely used in the World to produce heat and electricity at the same time in a same plant. The aim of this study, to analyze the performance of the production of power and heat for the food production process and the agricultural needs. For that reason, a basic cogeneration plant is taken to analyze the performance by using 1st and 2nd laws of thermodynamics and exergy analysis method. The electric-heat exergy rates, the energy and exergy efficiencies, the combustion chamber and the gas turbine outlet temperatures, the total electric and heat energies and exergies, and the specific works were calculated for various ambient temperatures and for various excess air rates of the basic cogeneration plants fueled with methane. The effects of the various ambient temperatures and the various excess air rates on the performance of the basic cogeneration plants were obtained, discussed and analyzed. For the best performance and for the best working conditions of the basic cogeneration plants in agriculture and food production process and food industry recommendations were done. It was found that, lower ambient temperatures give higher electric efficiency, but lower heat efficiency. However, an optimum excess air rates for the best performance was found at the value 2.3 of the excess air rates of the basic cogeneration plants fueled with methane. © The Authors, published by EDP Sciences
The Roles of Personality Traits, AI Anxiety, and Demographic Factors in Attitudes toward Artificial Intelligence
No full textThe present study adapted the General Attitudes toward Artificial Intelligence Scale (GAAIS) to Turkish and investigated the impact of personality traits, artificial intelligence anxiety, and demographics on attitudes toward artificial intelligence. The sample consisted of 259 female (74%) and 91 male (26%) individuals aged between 18 and 51 (Mean = 24.23). Measures taken were demographics, the Ten-Item Personality Inventory, the Artificial Intelligence Anxiety Scale, and the General Attitudes toward Artificial Intelligence Scale. The Turkish GAAIS had good validity and reliability. Hierarchical Multiple Linear Regression Analyses showed that positive attitudes toward artificial intelligence were significantly predicted by the level of computer use (beta = 0.139, p = 0.013), level of knowledge about artificial intelligence (beta = 0.119, p = 0.029), and AI learning anxiety (beta = -0.172, p = 0.004). Negative attitudes toward artificial intelligence were significantly predicted by agreeableness (beta = 0.120, p = 0.019), AI configuration anxiety (beta = -0.379, p < 0.001), and AI learning anxiety (beta = -0.211, p < 0.001). Personality traits, AI anxiety, and demographics play important roles in attitudes toward AI. Results are discussed in light of the previous research and theoretical explanations

Bugünlerde hemen hemen bütün problemli alanlara dair düzenlenmiş olan uluslararası çevre sözleşmelerinin, gerek bu problemlerin çözümü için siyasi oluşuma gerekse meselenin çözümünde hukuksal olarak bir dayanak oluşturması yönünden mühim fonksiyonları bulunmaktadır. Üstelik bu sözleşmeler taraflara kendi çevre politikalarını oluşturma ve uygulama hususunda da kılavuz olmaktadır. Söz konusu sözleşmelerin uygulanması aşamasındaki sorunlar uluslararası çevre sözleşmelerinin başarılı olmasına engel oluşturmakta ve bunların esas gayesi olan çevre meselelerinin çözümündeki etkileri tartışılmaktadır. Sözleşmelerin uygulanmasında önem taşıyan etkenlerin başında söz konusu sözleşmenin yapısı gelmektedir. Bundan dolayı bu çalışmada uluslararası çevre sözleşmelerinin uygulanabilirliği incelenmektedir Buna bağlı olarak bunların ana nitelikleri genel olarak değerlendirilmektedir. Sonra ise Birleşmiş Milletler İklim Değişikliği Çerçeve Sözleşmesi kapsamında, iklim değişikliğinin uyarlanması, azaltılması ve finansmanı hakkındaki Paris Anlaşması analiz edilmektedir. Paris Anlaşması'nın hem kapsamı hem de hukuksal yapısı incelenerek anlaşmaya dair uyum problemleri ortaya koyulmaya çalışılmıştır. Son bölümde ise ülkemizin uluslararası çevre sözleşmeleri ve Paris anlaşmasına uyumu değerlendirilmiştir.International environmental agreements, which have become a very important tool of global environmental management, are legal regulations that enable joint solutions to global environmental issues through international cooperation. Today, international environmental agreements on almost all problematic areas have important functions in terms of both the political formation for the solution of these problems and the legal basis for the solution of the issue. Moreover, these agreements also guide the parties in creating and implementing their own environmental policies. The problems in the implementation phase of the said conventions, which is a very important term in global environmental management, prevent the success of international environmental conventions and their effects on the solution of environmental issues, which are their main purpose, are discussed. The most important factor in the implementation of contracts is the structure of the contract in question. Therefore, in our study, the applicability of international environmental conventions is examined. Accordingly, their main characteristics are evaluated in general. Then, the Paris Agreement on climate change mitigation, adaptation and financing is analyzed within the scope of the United Nations Framework Convention on Climate Change (UNFCCC). By examining both the scope and legal structure of the Paris Agreement, harmonization problems related to the agreement were tried to be revealed. In the last part, our country's compliance with the international environmental conventions and the Paris agreement has been evaluated
