Mitochondrial dysfunction is an important part of the aging process. As the cells age, the efficiency of the respiratory chain decreases, electron leakage increases and ATP formation decreases. Different cell types have different numbers of mitochondria, and since they have their own DNA, they can divide independently of the cell they are in. In other words, mitochondrial replication is not dependent on cell division. During reproduction, half of a child's DNA comes from their father and half from their mother. However, the child always receives their Mitochondrial DNA (mtDNA) from their mother. The majority of mitochondrial diseases are caused by mutations in nuclear DNA that affect products that cause mitochondria. These mutations can be hereditary or spontaneous. When the mitochondria stop working, the cell they are in is deprived of energy. Therefore, symptoms can vary greatly depending on the type of cell. Cells that need the greatest amount of energy, such as heart muscle cells and nerves, are most affected by faulty mitochondria. 62 years ago, Harman suggested that aging is mediated by macromolecular damage caused by reactive oxygen species (ROS). ROS is produced in mitochondria as a byproduct of energy production, and these structures damage DNA, fats, and proteins. It is now focused on the target mitochondria in aging. Studies reveal that oxidative stress, mitochondrial DNA mutations, and a decrease in mitochondrial turnover mediate cellular aging. In this review, it is aimed to review the role of mitochondria in the human aging process on the basis of recent findings.</p> <p><strong>Key Words:</strong> Mitochondrial DNA; mitochondrial; aging; free radicals; oxidative stres</p> <p>&nbsp;</p> 2020-12-17T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/116 THE ROLE OF INFORMAL STRUCTURES IN ARCHITECTURAL DESIGN EDUCATION 2020-10-24T14:01:22+06:00 Huseyin Ozdemir hozdemir@ktun.edu.tr Gokce Ketizmen Onal gonal@ogu.edu.tr Aysen Celen Ozturk acozturk@ogu.edu.tr <p>Informal education contributes to the development of the student's design skills and the performance of architecture education by addressing subjects that do not fall directly into the curriculum. This study is mainly about the development of students' design thinking skills in informal education. In order to make an assessment, a case study was conducted on the Bademlik Design Festival (BTF), which can be described as an important example in the field of informal education. By adhering to the method, surveys were applied to the instructors and students participating in the BTF. The concepts obtained according to the survey results are based on a detailed conceptual framework. Then, by interpreting this conceptual framework, students' learning outcomes are revealed. As a result, it is observed that the students in the workshops conducted at the BTF gain design thinking skills such as “interaction, free and original thinking, innovation, communication and dialogue”.</p> 2020-12-17T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/128 Adsorption of carbon dioxide on MIL53(Al), CuBTC and K- NaX zeolite 2020-11-11T02:00:30+06:00 Fehime Cakicioglu-Ozkan fehimeozkan@iyte.edu.tr <p>CO<sub>2</sub> adsorption on K exchanged NaX zeolites, and metal organic frameworks (MOFs), namely Cu-BTC and MIL53 (Al) was studied at 5 °C and 25 °C.&nbsp; Exchange via ultrasonic and traditional methods, was conducted at 50 °C and 70 °C. The maximum replacement of Na<sup>+</sup> ion with K<sup>+</sup> ion in the extra framework of zeolite was increased from 76% to 83% with increasing temperature from 50 °C to 70 °C in the ultrasonic method which is more effective than traditional one. Compared with the zeolites, the MOF adsorbents used in this work have higher Langmuir specific surface area values namely 1278, 1473 and about 1000 m<sup>2</sup>/g for MIL 53, Cu-BTC and zeolite adsorbents respectively. The resulting CO<sub>2 </sub>isotherms can be well represented by the Toth equation. Comparison of the isosteric heat of adsorption at zero loading shows that CO<sub>2 </sub>was adsorbed more weakly on MOFs than zeolites.</p> 2020-12-17T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/131 COINCIDENCE AND COMMON FIXED POINT THEOREMS IN Ƒ-METRIC SPACES 2020-12-09T22:24:42+06:00 Demet Binbaşıoğlu demetbinbasi@gmail.com <p>Recently, the concept of Ƒ metric space has been introduced and have been defined a natural topology in this spaces by Jleli and Samet[6]. Furthermore, a new style of Banach contraction principle has been given in the Ƒ metric spaces. In this paper, we prove some coincidence and common fixed point theorems in Ƒ metric spaces.</p> 2020-12-17T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/133 A SAFE NAVIGATION PROPOSAL FOR KANAL ISTANBUL: INTEGRATED TUG-BARGE SYSTEM 2020-12-19T03:13:29+06:00 İrşad BAYIRHAN ibayirhan@istanbul.edu.tr <p>"Canal Istanbul", officially announced in 2011; is an alternative waterway project to the Strait of Istanbul, designed to relieve ship traffic. The main intention of relieving the ship traffic is to transfer the tanker traffic, which poses a significant risk to the Istanbul metropolis, to Canal Istanbul. On the basis of the criticisms made to the project in line with the determined dimensions, another risk factor, the issue of safe navigation opportunities and the economic criterion of the lower tonnage transportation that arises in this sense come to the fore.</p> <p>In fact, in all artificial canals in the world, before the project is created compared to natural water passages (channels), similar concerns are experienced among the parties of maritime transport and the necessary projection studies are carried out. Likewise, such studies have been carried out for Canal Istanbul and the simulations have been verified in terms of navigation. The main issue that causes concern here is the question of to what extent a ship with the dimensions based on simulations will be commercially and technically effective compared to the existing fleet. However, the optimum usage of such a water passage can be solved by a set of transportation engineering strategies and a system that puts the competitive and environmentalist side of canal use in the foreground.</p> <p>In this study, the integrated tugboat-barge system (ITBS) is thought to be the most ideal transportation system for Canal Istanbul, whose has not been completed yet. The contribution of the ITBS system, which is widely used in world canal and water transport, to the optimum use of existing waterways and its being environmentally friendly, has been the main motivation for this study. A detailed literature study has been made on the subject, the examples of this form of transportation in the world have been examined and the form usable for Canal Istanbul has been specified. In addition, the criticisms made about Canal Istanbul formed the set of problems in the study, and reasonable solutions were offered to these problems with the usefulness of the proposed transportation system, and the advantages of the system were explained.</p> 2020-12-18T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/134 TERMS RELATED TO PRACTICE RULES AND REGULATIONS OF ORGANIC BEEKEEPING PRODUCTION IN TURKEY 2020-12-27T02:30:26+06:00 Lale Taş alina.amanzhol07@gmail.com <p>Organic farming production; To the extent permitted by the regulation, it is a production in which chemical drugs are used that are friendly to human health and nature, and do not harm the environment and human health; It is a form of production that gives priority to the quality of the product rather than the amount of manufacture, and every stage is checked and certified by control and certification.</p> <p>Organic Beekeeping, on the other hand, does not apply chemical drugs and artificial nutrition to bees at every stage from production to consumption, It is a production that is carried out on intact natural flora or organic farming areas and is controlled and certified by control certification companies.</p> <p>Beekeeping; producers with low income, especially in rural areas, both in European countries and in our country and it is an important source of income for producers who do not have land. With this aspect, it adds added value at the micro-level in the rural areas and at the macro level in the country's economy.</p> <p>The products obtained from bees are faced with the threat of risk factors that negatively affect food safety during the process of taking their place on the market shelves from production. For this reason, the importance of organic beekeeping increases as the aim is to increase the quality of organic beekeeping.</p> <p>According to the Organic Agriculture Information System (OTBİS) of the Ministry of Agriculture and Forestry, in 2019, There are 249 enterprises engaged in organic beekeeping in Turkey. Organic beekeeping, the total number of organic hives is 50.100 and the total organic honey production is 576.76 tons.</p> <p>Moreover according to the Organic Agriculture Information System of the Ministry of Agriculture and Forestry, in 2019, 159 enterprises engaged in beekeeping in the transition process in Turkey present, it has a total of 21 484 hives in transition.</p> <p>To increase this potential of our country and to ensure its sustainability, It can be achieved by producing reliable and better quality organic beekeeping products. For this, the production and consumption of organic beekeeping products should be expanded.</p> 2020-12-27T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL http://icontechjournal.com/index.php/iij/article/view/135 CHANGES IN THE ONLINE FOOD AND MEAT SHOPPING HABITS OF TURKISH ADULTS DURING COVID-19 PANDEMIC 2021-01-05T18:00:23+06:00 Güliz HASKARACA gyaldirak@sakarya.edu.tr Esra BOSTANCI esra.bostanci@beun.edu.tr <div><span lang="TR">In the current study, food and meat shopping/online shopping behavior of Turkish adults were investigated and analyzed comprehensively, during COVID-19 pandemic. For that purpose, a survey with 19 questions was administered with the attendance of 494 people from Turkey. According to the findings, 42.8% of the participants did online shopping for food and 28.5% of them bought meat and meat products online, before the COVID-19 pandemic. These figures rose to 44.7% and 44.32%, respectively, after the COVID-19 pandemic. Online meat shopping has increased during COVID-19 pandemic. However, more than half of the participants did not prefer to buy meat products online, because of the concerns about the spoilage of meat until the products were delivered. If there was a mobile tracking system which allows users to track the conditions of the product during transportation, 56% of the participants who did not initially prefer to do online meat shopping reported that they would have ordered meat online. This study has shown that; it is very important to implement mobile tracking systems in terms of the continuity of the food chain in processes such as pandemics. This study will contribute to the creation of mobile tracking systems to be established in the future, for the food industry</span></div> 2020-12-17T00:00:00+06:00 Copyright (c) 2020 ICONTECH INTERNATIONAL JOURNAL
