Türkiye’nin Doğu Akdenizi’nde Chrysopid’lerin (Neuroptera: Chrysopidae) ekolojik dağılımı ve mevsimselliği

This study was conducted to establish Chrysopidae fauna and assess habitat preferences and diversity of species in the East Mediterranean Region of Turkey. The specific family (Neuroptera: Chrysopidae) in this region is poorly known and this survey. Traps (sweeping net, light traps) were used to catch of Chrysopidae species from all study sites at the four provinces (Adana, Hatay, Mersin, Osmaniye) in the East Mediterranean Region of Turkey between the years 2012 and 2013. The most abundant species were Nineta flava (Scopoli, 1763). From all sites a total of 1841 Neuroptera were trapped, representing 18 species. All the species were found in all sites while species Chrysopa dorsalis Burmeister, 1839, Chrysopa viridana Schneider, 1845, Chrysopa astarte Hölzel, 1967 were confined to 3 sites. All the species reached peak abundance respectively in the June and July. The appearance and distribution of the Chrysopidae species were strongly linked with seasonal changes.Bu çalışma; Türkiye’nin Doğu Akdeniz Bölgesindeki Chrysopid’lerin fauna, habitat tercihleri ve tür çeşitliliğini değerlendirmek amacıyla yürütülmüştür.

The presence of R. sumatrae (Weber, 1801) in Vietnam is confirmed. An updated key to all recorded species of the genus Ropalidia from Vietnam is also provided

INVESTIGATION OF SELF CONFIDENCE LEVELS OF SECONDARY SCHOOL STUDENTS ENGAGED İN INDIVIDUAL AND TEAM SPORTS

Introduction and aim: In sports, self-confidence can be characterized by high-grade achievement expectation. In this context, the aim is to determine whether is any difference between the self-confidence levels of middle school students who do individual sports and those who are engaged in team sports. Age groups and gender as well as differences in self-esteem levels are also analyzed.Method: The study group consisted of 96 students who were engaged in individual and team sports in 5 secondary schools in Istanbul. "Coopersmith Self-Esteem Inventory", developed by Coopersmith (1967), was used in order to determine self-esteem levels and the personal information form was prepared to collect participants' age, gender and sport type data. First, the Shapiro Wilk test was performed to test the distribution of the data and it was found that the data provided a normal distribution. Independent sample t-test was conducted to determine whether self-esteem levels differed significantly in terms of gender and age variables.Findings: At the end of the study, the findings obtained from the data analysis showed that there was no significant difference in the self-confidence levels of the secondary school students compared to the sports types (p> 0,05). In the data obtained from other variables, it was determined that the level of self-esteem did not show any significant difference according to age and sex (p> 0,05).Discussion: There was no significant difference between the presented study and the mean scores of confidence, age, sport type and gender (p> 0,05). It can be said that no definite decision has been reached on whether this self-confidence is influential or not according to the results of this sample and the results of the researches made. It is advisable to add lessons such as communication skills, human relations in order to improve curriculum self- confidence building levels in schools.  Article visualizations

COMPARISON OF TURKEY'S ACADEMIC PUBLICATION PERFORMANCE IN ASTRONOMY EDUCATION WITH OTHER COUNTRIES ACCORDING TO WEB OF SCIENCE DATABASE

In this study, a bibliometric evaluation of the articles published between 1975 and 2020 in astronomy education in the Web of Science database is aimed to reveal the trend in this field and to compare the articles from Turkey with other countries. During the article search process, the keyword "astronomy" was scanned both in the title and content of the articles. A total of 284 articles were reviewed under the Education/Educational Research category. VOSviewer (V1.6.15) package program was used to create and visualize bibliometric network maps of the articles examined within the scope of the study. In the findings, it was seen that approximately four-fifths of the articles published in the field of astronomy education have been published in the last ten years. It was determined that the most effective country in which publications are made on astronomy education is the USA, and Turkey is in the second place with 25 articles. It is noteworthy that while the average number of citations per publication for all the articles examined is 14.62, the average number of citations for articles originating from Turkey is 3.56. Based on such findings, Turkey's academic publication performance in astronomy education has been tried to be revealed

Development of electrochemical biosensor platforms for determination of environmental viral structures

Infectious diseases caused by viruses (such as influenza, Zika, human immunodeficiency, Ebola, dengue, hepatitis, and COVID-19 virus) are diseases that have been on the agenda of the whole world for the last quarter of a century and have become one of the most important problems for people. Urgent identification of the people infected with a disease will allow these people who have contracted the disease to be treated effectively. In this context, the polymerase-chain-reaction (PCR)-based methods have been the most common and widely used method that responds with sensitivity. However, due to some disadvantages encountered in PCR applications (in particular, the test protocol is comprehensive, not fast in terms of time, not economical, requires user expertise, is not suitable for field/on-site measurements, etc.), a new generation (which can give fast results, are economical, sensitive, suitable for on-site application, etc.) of systems that can provide solutions are needed. On the subject of different test-diagnostic applications used in a large number of test-based analysis methods and techniques, electroanalytical systems have some advantages. Within the scope of this presentation, low-cost, miniaturized electrochemical platforms for surface-printed electrodes by using appropriate biochemical and viral structures of the electrode surfaces decorated with suitable agents are explained. These platforms can be used in the determination of some particular viral proteins for the understanding of viral pathogenic diseases. In this study, a copper-modified graphite electrode was developed and characterized with SEM. Afterwards, an antibody of the N protein of COVID-19 was decorated surrounding this electrode to measure the amount of that protein in the samples. The square wave voltammetry (SWV) technique was used for the electrochemical detection of SARS-CoV-2. When the results of the analyses were examined, the best analytical sensitivity and linearity were obtained by incubating the antibody-modified electrode and virus antigen for 10 min. The measurements showed linearity with a high correlation coefficient (R2 = 0.9917). The detection limit (LOD) was calculated as 508 pg/mL. The measurement limit (LOQ) was calculated as 1.54 ng/mL. With the pencil tip, which is an easily accessible material for the modified electrode system we designed, a very precise measurement was provided for the rapid detection of the N protein of the SARS-CoV-2 virus at very low concentrations

An analysis on the corrosion of a cultural heritage

Many historical landmarks and cultural heritage are being constantly destroyed through natural events and human actions. It is important to conduct corrosion analysis and two and three-dimension documentation studies to restore and transfer these landmarks to the new generations. It is particularly important to record, keep these historical heritages digitally and take precautions against the potential corrosion due to the wars, natural disasters and climatic factors that continue to the present. In this study, the corrosion in Çanlı Church (ÇanlıKilise) located in Akhisar village of the province of Aksaray in Turkey was determined and the reasons were examined. By using close-range photogrammetry method, three-dimension models and facade charts of three facades (North, West, South) of Çanlı Church have been acquired, as a result of measurements performed in four different times (2006, 2010, 2016, 2019). Overlapping all these charts in the same scale, the corrosions occurred on the facades of Çanlı Church have been examined. The meteorological data within the period when the measurements were performed were reviewed. As a result, corrosion on the North, West and South facades of Çanlı Church have been found at the level of 8%, 3%, 13% respectively. It was concluded that the storm has greater effect on the corrosion
