The study group of the study consists of 847 secondary school students’ who study in public schools in Selcuklu central district of Konya province in 2018 2019 academic year. The screening method, one of the quantitative research methods, was used in the research. As data collection tool; “Personal Information Form” developed by the researcher to reach the personal information of secondary school students, “Digital Citizenship Scale” developed by Som-Vural to determine the levels of digital citizenship, and “Digital Literacy Scale” developed by Hamutoglu and others to determine the levels of digital literacy was applied. At the end of the study, it was concluded that the digital citizenship levels of secondary school students were high. It was concluded that there is a significant difference between the levels of digital citizenship of secondary school students and the year of internet use. It is concluded that there was no significant difference between gender, class level, time spent on daily internet time variables and secondary school students' digital literacy levels. There was no significant difference between class level variable and digital literacy level. In the correlation analysis conducted to determine the relationship between digital citizenship levels and digital literacy levels of secondary school students, it was found that there was a positive directional and significant relationship at the, medium-level. In addition, the effect of digital literacy on digital citizenship was found to be positive directional and significant.","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87322078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With these factors threatening human health, the term sustainability gained popularity for restoring the deteriorating ecological balance. This awareness is called green buildings in the construction sector. The purpose of sustainable green buildings is the restoration of corrupted order and utilization of energy effectively. The Life Cycle Assessment method is one of the assessment systems developed for reducing the environmental impacts of products/services in evolving green buildings. Life Cycle Assessment determines the environmental impacts of the process that studies the extraction, use and disposal of the material by taking the life long evaluation of any product. As a result of this study and the in depth review of the literature portrayed the pros and cons, and the applications of the terms sustainability, green buildings and life cycle. The application stages of Life Cycle Assessment are defining the purpose and concept, stock analysis, analysis of effectiveness, evaluation of subfields with a determination of the boundaries as initial, intermediate and final. With the final analysis, the aim is to produce environmentally friendly products/services.

Methods: To enhance a suitable research questionnaire which be composed of with five dimensions questionnaire: excessively use of smartphone (EUS); psychosomatic-social dimension (PSD); well-being dimension (WD); anxiety with smartphones (AS) and high-tech dimension (HTD). A group of 520 university students, with 267 male and 253 female students, at MBSTU students was interviewed. Results: Result showed that 42.87% participants was highly addicted in smartphone and faced PBC problem. In the basis of respective dimensions was found the statistically significant gender distinctions in the addictions of smartphone and most of time prefer in male students. There are significant differences was found by marital status which in prefer in unmarried students and use of the smartphone for greater than or equal to 4 hours in a day, by several hours of casual usage. Highest degree of smartphone addiction were found in Bachelor degree students with compare to Master’s degree students. As like for the monthly earning, statistically significant distinctions in well-being conditions were set up the respondents of the lower monthly earning family. Conclusion: PBC problem among University students in MBSTU are at risk of smartphones addiction; PBC phenomenon is significantly associated with negative or bad effects on daily academic life and performance.","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79420466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While human beings are in a technological production, they have also designed. Design has altered with the effect of developing technology and has sometimes taken advantage of technological possibilities in different periods of history and has guided it with the vision it has created. Thus, design and technology have always been concepts that affect each other, and the application forms of art and design have changed and developed with technology. In time, the expression of artistic products and computer technologies with hardware and software has created art in digital environment. Just as every technological development is reflected in art and design as new possibilities of use, every new digital work has become a subject that contributes to the development of this new medium from different angles. In this article, the new possibilities brought to the fields of art and design by the digital medium that emerged with the computer technologies that mankind has reached through various periods are discussed with an approach that investigates how traditional methods and techniques are affected by new technologies.

{"title":"β-galactosidase and Annexin V/PI Assays as QC Tests for Manufacturing cGMP-Grade Wharton Jelly Derived Mesenchymal Stem Cells","authors":"Gulnaz Yildirim Koken","doi":"10.7176/jstr/6-12-07","DOIUrl":"https://doi.org/10.7176/jstr/6-12-07","url":null,"abstract":"Background: According to the guidelines for cGMP, strictly regulated procedures and quality control (QC) tests are required. However, none of the regulations by authorities suggested have β-galactosidase and Annexin V/PI assays as QC tests. In this study, we aimed to demonstrate the feasibility of Annexin V and β-galactosidase assays as valid cGMP-compliant QC tests. Methods: Wharton’s Jelly derived mesenchymal stem cells (WJ-MSCs) were isolated, characterized and screened as valid QC tests. In this study, in addition to routine QC tests, β-gal assays were performed to confirm telomerase activity and Annexin V methods were used to confirm cell viability assays. Results: It was concluded that one donor (WJ-MSC-3) has higher telomerase activity and it has lowest β-gal activity at the same time (p<0,001). Only one donor showed significant difference in annexin V viability tests, indicating the importance of using automatic devices and Annexin V to manual tests for cell viability analysis (Muse: 92,48 ± 0,487% Flow Cytometry: 90,76 ± 1,116% p<0,01). Conclusion: With these existing data, telomerase activity and senescence levels may correlate and affect MSC quality in cell based therapy. In order to determine the viability values by adding Annexin V based automated methods could give more guaranteed results. characteristics and differentiation capacity of MSCs Age related differences are minimal in WJ derived MSCs samples as compared to other adult sources. MSCs harvested from the WJ are considered “young”, much more proliferative, immunosuppressive, and even more therapeutically active than those isolated from ‘’older’’, adult tissue sources 44]. Our results together with the previously reported studies in the literature suggest that adult-derived mesenchymal stem cells will have more significant differences in senescence levels. Surprisingly, although RTA level of 3 of 4 different WJ-MSCs were very close to each other; telomerase activity of WJ-MSC-3 is significantly higher than others. With the present data in mind, telomerase activity and senescence levels may correlate and also may affect MSC quality in cell based therapy.","PeriodicalId":14256,"journal":{"name":"International Journal of Scientific and Technological Research","volume":"498 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80030643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
