What is a Fairy Tale? Defined in the Turkish Language Association Turkish Dictionary as "a literary genre that is generally created by the public, based on imagination, living in oral tradition, and describing extraordinary events experienced by mostly humans, animals, witches, demons, giants, fairies, etc.", fairy tales are an important cultural wealth of oral literature that has been passed down from generation to generation. Fairy tales help develop the imagination, attention, memory, language skills and vocabulary of the listeners, as well as helping them gain reading and listening habits. It is also known that children who grow up with fairy tales are more curious and ask questions. We the Atatürk Cultural Centre, an affiliated institution of the Atatürk Supreme Council for Culture, Language and History, protect Turkish Fairy Tales. We have achieved a first in the history of Republic of Türkiye. Our entire collection of fairy tales from the pre-Islamic period to the present day is presented to our people through a database with the technology required by the age. We are taking ownership of our own fairy tales with a comprehensive corpus study. We took an important step in this regard with the Turkish Fairy Tale Collection Project that we started approximately five years ago. With this project, known as TÜMAK in short and supported by our Presidency, we first started to compile fairy tales within Türkiye. The fairy tales collected from all over the country with the technological means required by the age were first examined by editors who are experts in the field, and then fairy tale texts with the characteristics of their genres were selected and written unity was ensured among them. Finally, the fairy tales were made accessible through www.masal.gov.tr with the approval of the Project Scientific Board, which consists of distinguished scientists in the field. The most beautiful Turkish tales were selected from the texts compiled within the scope of TÜMAK using a scoring rubrik. Some of the selected tales were rewritten, illustrated, made into audiobooks and published under the supervision of an expert committee. Within the scope of the Selections from Turkish Tales for Children Project, 25 stories, completed in three stages, were distributed to children free of charge. Our Application, "Stories of Türkiye" We wanted to read our children and grandchildren to sleep and raise them with our own fairy tales. We offered our fairy tales to parents with the technological possibilities required by the age. Thanks to the mobile application we named "Stories of Türkiye", developed by our institution's IT experts, we grouped our fairy tales according to their provinces of origin and their types. We shared fairy tale texts for those who love reading fairy tales. We provided audiobook versions for each of our fairy tales for those who love listening to fairy tales. We prepared the opportunity for our fairy tales to be listened to not only in Istanbul Turkish but also in the dialect of the region they belong to for the first time in Türkiye. In this way, we tried to draw attention to fairy tale telling with local colors and keep the tradition alive. We would like to thank our Esteemed President, Minister, our Supreme Council and Presidency Presidents, who have always supported the realization of this project and mobile application. On the other hand, we would like to thank the Project Implementation Committee, who have worked hard for five years in an insistent and consistent manner in the implementation of this project, all the personnel of our Institution and our scholarship holders.

Independent trainer for the four NERC System Operator Certification exams: RC, BT, TO and BI. Scored against the cut score, never a percentage. 1,224 original questions, timed mock papers, a control-room simulator. Power Grid Operator Exam Prep covers the four System Operator Certification examinations of the North American Electric Reliability Corporation (NERC): Reliability Coordinator (RC); Balancing, Interchange and Transmission (BT); Transmission Operator (TO); and Balancing and Interchange (BI). One bank, four credentials All four examinations are drawn from the same six content domains and 31 knowledge areas; only the number of scored questions per area changes, and that table is published. Pick your credential and the app re-weights your readiness estimate, weak areas and mock papers. Scored the way the examination is NERC passes candidates on an absolute cut score, not a percentage: 92 of 120 for RC and BT, 76 of 100 for TO and BI. So the headline figure is a projected score out of the paper, and weak areas are ranked by how many scored questions they are costing you. Mock papers sampled to the outline A mock paper draws exactly the questions the content outline lists for each of the 31 knowledge areas, plus the 20 unscored trial items a real paper carries: 140 questions in three hours (120 on TO and BI). Flag and return, no feedback until you submit, then a full review with a reference on every question. The control-room simulator Take a shift at the BA, TOP or RC desk in nine scenarios, from a unit trip at the evening peak and an IROL exceedance to EEA 3, a lost EMS, voice paths down and an evacuated control room. One model runs the system and the clock stops at each decision: read the live displays, choose what to do or answer a three-part communication, then watch it play out. The debrief counts, never as a percentage, the obligations you met or missed against the standards' own clocks, and explains every decision. Every number is tagged as a NERC figure, a value your company or RC sets, or a model assumption. New numbers every run. Home opens on a scenario for your credential: one tap starts a shift. Generated displays, new every time A six-bus one-line with flows, ratings and an N-1 contingency analysis report: find the worst contingency and decide what it obliges you to do. A Balancing Authority AGC control board, with the ACE left for you to calculate. Plus twenty calculation drills. 1,224 original questions Written from freely published sources (content outlines, the NERC Glossary and the enforceable Reliability Standards). Each is tagged recall, application or analysis. One free shift, then one payment Try it free: 50 practice questions in any mode, one full mock paper, one simulator run of any scenario, and every Library card. Full Access is a single in-app purchase that unlocks every question, unlimited mock papers on all four credentials, every trainer and all nine scenarios. One-time, no subscription, on your iPhone, iPad and Mac. The rest of the app 31 Library cards, each with seven must-know numbers and a short essay. Keyboard shortcuts on iPad and Mac. Spaced repetition brings back what you miss. Works offline and syncs through your own iCloud, with no account and no data collected. Light and dark, with a manual override.
