Validated RP-HPLC Method for Quantification of Phenolic Compounds in Methanol Extracts of Aerial Parts and Roots of Thymus sipyleus and Evaluation of Antioxidant Potential

Purpose: To evaluate the total phenolic content and antioxidant potential of the methanol extracts of aerial parts and roots of Thymus sipyleus Boiss and also to determine some phenolic compounds using a newly developed and validated reversed phase high performance liquid chromatography (RP-HPLC) method.Methods: The total phenolic concentration of the extracts were determined using Folin Ciocalteu method. The antioxidative potential of the samples was evaluated using DPPH and ABTS assays. Phenolics responsible for the antioxidant activity of the plant were quantified by a newly developed and validated RP-HPLC method for the first time.Results: The total phenolic concentration of the aerial parts and roots were 215.1 ± 2.24 and 152.25 ± 2.31 mg GAE/g extracts, respectively. The extract obtained from the aerial parts reduced DPPH with a half-maximal inhibition concentration (IC50) of 0.703 ± 0.027 mg/mL, while the IC50 obtained from ABTS assay was 0.869 ± 0.066 mg/mL. IC50 values of Trolox used as standard for DPPH and ABTS radical scavenging assays were 0.0430 ± 0.0001 and 0.0420 ± 0.0001 mg/mL, respectively. The results revealed that T. sipyleus contains remarkable amounts of rosmarinic acid in the aerial parts (0.8887 ± 0.0016 g/100g dw) and in the roots (0.3454 ± 0.0006 g/100g dw) which is believed to be mostly responsible for the observed activity.Conclusion: T. sipyleus is a major potential antioxidant source for the food, pharmaceutical and cosmetic industry due to its high contents of rosmarinic acid and total phenolics.Keywords: Thymus sipyleus, Rosmarinic acid, Chlorogenic acid, Caffeic acid, Apigenin, Antioxidan

Revisión de cuentos populares Turcochipriotas sobre desarrollo infantil

Tales are among the most important literary genres of child literature which plays an essential role in the development of pre-school children. In addition to entertaining children, tales also prepare them for life, and are frequently used by both pedagogues and families as an extremely important genre. The child, who identifies himself with the hero in the fairy tale, gains the spirit of struggle knowing that there is a solution to the difficulties he may see in life. In addition, fairy tales play an important role in developing children's imagination and in providing them with listening and speaking skills. Therefore, the educational functions of fairy tales are important in every country and it is emphasized that the growth of children with fairy-tales especially in pre-school period is very important for their social and psychological development. Despite these important benefits of tales, it is a known fact that not all tales can be told to children. Therefore, the tales to be used in the education of children should be carefully selected. First of all, fairy tales should be chosen according to the level and development of the child. In addition, as in every country's tales, Turkish Cypriot folk tales have elements that can adversely affect the psychological and social development of children. Families and teachers should take due care and be selective. In this research, 15 Turkish Cypriot folk tales selected by random method were examined and effort is paid to determine and evaluate elements that could be harmful to children.Los cuentos son uno de los tipos literarios más importantes de literatura infantil que desempeña un papel esencial en el desarrollo de los niños en edad preescolar. Además de entretener a los niños, los cuentos también los preparan para la vida, y los educadores y las familias los usan con frecuencia como un género extremadamente importante. El niño, que se identifica con el personaje principal del cuento de hadas, adquiere el espíritu de lucha sabiendo que hay una solución a las dificultades que puede encontrar en la vida real. Además, los cuentos de hadas juegan un papel importante en el desarrollo de la imaginación de los niños y en proporcionarles habilidades para escuchar y hablar. Por lo tanto, las funciones educativas de los cuentos de hadas son importantes en todos los países y se enfatiza que el crecimiento de los niños con cuentos de hadas, especialmente en el período preescolar, es muy importante para su desarrollo social y psicológico. A pesar de estos importantes beneficios de los cuentos, es un hecho conocido que no todos los cuentos se pueden contar a los niños. Por lo tanto, los cuentos que se utilizarán en el proceso educativo de los niños deben seleccionarse cuidadosamente. En primer lugar, los cuentos de hadas deben elegirse de acuerdo con el nivel y el desarrollo apropiados del niño. Además, como en los cuentos de cada país, los cuentos populares Turcochipriotas tienen elementos que pueden afectar negativamente el desarrollo psicológico y social de los niños. Las familias y los maestros deben tener el debido cuidado y ser selectivos. En esta investigación, se examinaron 15 cuentos populares Turcochipriotas seleccionados al azar y se hizo un esfuerzo para determinar y evaluar elementos que podrían ser perjudiciales para los niños

Valores socio-culturales proporcionados a niños preescolares utilizando juegos tradicionales para niños

With the development of technology, traditional games which had an essential place in the lives of children began to lose their importance and were replaced by computer games. An examination of developed countries shows that their unique traditional games are being protected and, thanks to conscious families are nurtured by national values; thus, they serve an extremely important function in terms of shaping national conscience. The value of traditional children’s games can be better understood considering the possibility that especially pre-school children can be affected by the artificial and virtual culture imposed by technological devices. Pre-school period is a period when value education in children begins. Information on values is gained at every stage of life. However, the earliest information is acquired through traditional games in the period when personality begins to develop. In this study, 25 children were presented with Cypriot Turkish children’s games such as hide-and-seek, house, blind man’s buff, dodge ball and duck duck goose. Then children were urged to play these games and observations were made which was followed by interviews with children to obtain their opinions on games and game processes. In the study, it was seen that children acquired several values required by social life such as respect, courtesy, helping each other, courage, love, protection, honesty, forgiveness, respect for the environment, patience, and obeying rules.Con el desarrollo de la tecnología, los juegos tradicionales, que tienen un lugar importante en la vida de los niños, han comenzado a perder su importancia en el proceso y su lugar ha sido reemplazado por juegos de computadora. Cuando se mira a los países desarrollados, se ve que los juegos tradicionales están protegidos, y se ve que estos juegos los juegan los niños a través de familias conscientes y maestros. Dado que los niños en edad preescolar pueden verse influenciados por la cultura artificialvirtual a través de medios tecnológicos de comunicación, el valor de los juegos infantiles tradicionales se comprenderá mejor en este punto. El período preescolar es un período en el que la educación en valores comienza en los niños. Mientras que la información sobre los valores se obtiene en cada período de la vida, la primera información se obtiene mediante los juegos tradicionales en el período en que la personalidad comienza a formarse. En este estudio, a 25 niños se les presentaron juegos de niños turcos chipriotas como escondite, casa, aficionado a ciegos, dodge ball y pato pato ganso. Luego se instó a los niños a jugar estos juegos y se hicieron observaciones, seguidas de entrevistas con niños para obtener sus opiniones sobre los juegos y los procesos de juego. En el estudio, se observó que los niños adquirían varios valores requeridos por la vida social, como respeto, cortesía, ayuda mutua, valor, amor, protección, honestidad, perdón, respeto por el medio ambiente, paciencia y obediencia a las reglas

The Impact of a Research Methods Course on Teacher Candidates’ Epistemological Beliefs

The epistemological beliefs of teachers impact both their in-class practices and the perceptions and beliefs of the students whose learning is the responsibility of teachers. Therefore, this study aims to investigate and discuss the impact of a course entitled “research methods” which is taught in education faculties in Turkey, on the epistemological beliefs of teacher candidates. The study adopted the mixed-methods sequential explanatory design. Forty-three teacher candidates participated in the study. The data for the study were collected through the “Scientific Epistemological Beliefs Scale (SEBs)”, a semi-structured interview form, and another form that included the written opinions of teacher candidates. The findings revealed that the research methods taught to teacher candidates do not have a statistically significant impact on their epistemological beliefs. But the analysis of the semi-structured interviews with teacher candidates and their written comments revealed that the teacher candidates explained the nature of knowledge, its sources, and the way scientists work through the traditional understanding of science

EXAMINATION OF THE ENVIRONMENTAL AWARENESS PRIMARY SCHOOL STUDENTS AND THEIR ATTITUDES TOWARDS THE ENVIRONMENT

In this study, it is aimed to determine the environmental awareness of primary school students and their attitudes towards the environment. The environmental awareness and attitudes towards the environment of 4th grade primary school students have been examined according to the variables of gender, mother's education level, and father's education level. Relational survey model, one of the quantitative research methods, was used in the research. The study group of the research consists of 90 primary school students (54 girls, 36 boys) studying in a public school in the Central Black Sea Region in the 2020-2021 academic year. The research data has been collected using the "Primary School Environmental Awareness Scale" developed by Yıldız Yılmaz and Mentiş Taş (2017) and the "Primary School Environmental Attitude Scale" developed by Artvinli and Demir (2018). Pearson Correlation Analysis was used to find the relationship between students' environmental awareness and attitudes towards the environment in the data obtained in the study. In order to determine whether primary school students' environmental awareness and attitudes towards the environment change according to the determined variables, the distribution of the data was examined and Pearson Product-Moment Correlation, Two-Factor ANOVA for Unrelated Samples, Mann-Whitney U Tests from Non-Parametric Test methods were applied. According to the research findings, it was determined that the general averages of environmental awareness and the environmental responsibility in the sub-dimension of primary school students were at a high level, the sub-dimensions of life in nature and the recyclable energy sources and their usage were at a very high level, and the sub-dimension of the continuity of living things was at a moderate level. It has been found out that the environmental awareness of primary school students has not changed according to the variables of gender, mother's education level, and father's education level. It has been determined that the attitudes and sub-dimensions of primary school students towards the environment are at a moderate level. There was no statistically significant difference in the attitudes towards the environment and its sub-dimensions according to the educational status of the mother. A significant difference has been found in the positive environmental behaviors sub-dimension, which is one of the environmental attitude sub-dimensions, according to the educational status of the father. There was no statistically significant difference between primary school students' environmental awareness and their attitudes towards the environment. In order to increase students' environmental awareness and attitudes towards the environment, it is recommended to plan theoretical and applied activities by associating them with different courses.  Article visualizations
