Title: The Woman’s Role in the Contemporary World<br/><br/>Authors: Glouhtcheva, Tania<br/><br/>Abstract: In the XXI - st century the woman still doesn’t know where she stands in the world. What’s her role? To be a housewife? Or a caring mother and good wife? Or someone seeking career? Or does she do all this at the same time? According to many people the feminist movements which began at the end of the XIX –th century and had a key role during all the next century – are part of the past. The populist far right – wing parties blame them for causing more problems than giving benefits. Is it there fault that the European population is mainly old? Which are the good practices that should be preserved? The aim of the following paper is to give answers to the questions above by using the comparative analysis – to compare the feminist’s and the far right-wing populist politics, content analysis, the interdisciplinary method and the deductive method.The work will show where the Bulgarian woman stands compared to the European woman. The topic is very important nowadays and there are still not many researches made, that’s why the paper will put a start to future scientific work in this field.<br/><br/>Description: През XXI век мястото на жената в света продължава да бъде неясно. Каква й е ролята? На домакиня? На любяща майка и добра съпруга? На кариеристка? Или да изпълнява всички тези роли накуп? Според мнозина времето на феминистките движения, които започват в края на XIX век и имат ключова роля през цялото следващо столетие – вече е отминало. Крайнодесните популистки партии ги обвиняват в нанасяне на повече вреди, отколкото ползи. На тях ли се дължи застаряващото население в Европа? Кои полезни практики трябва да се запазят? Настоящият доклад има за цел да отговори на гореспоменатите въпроси посредством сравнителен анализ на феминистките и крайнодесните популистки политики; контентанализ, интердисциплинарния метод и дедуктивен подход. Трудът ще проследи и мястото, което заема българската жена в сравнение с европейската. Темата е актуална и все още не е много изследвана, затова докладът ще постави основите на бъдеща изследователска дейност в тази сфера.Theopsychological Interpretation of Stress

Title: Theopsychological Interpretation of Stress<br/><br/>Authors: Valkov, Ivan<br/><br/>Abstract: The article argues that any study of stress only on a mental and physical level is complete. Recent research in medicine and psychology complements the analysis, but is not sufficient to formulate workable solutions. There are five directions in the study of stress reactions: biological, medical, psychological, socio-psychological, to which in this text we add theo-psychological. Stress has deep psychophysiological and psycho-spiritual roots, although only in the last century its influence, causes and results have been talked about by psychologists, physicians and educators. The author examines the history of stress from a theological perspective, focusing on its spiritual dimension. Based on the available psycho-spiritual external and internal stressors, stress is defined as a complex human response to external and internal stimuli that cause tension and shock in the human mind, soul and body. From the moment of the severance of the relationship with God, on a subconscious level in man there is a constant feeling of guilt, fear of unexpected and unknown danger. This psycho-spiritual fixation is triggered in extreme situations caused by external stimuli, the reason being lack of support, confidence on a spiritual, mental and physical level. The Bible describes this pattern as follows: "The wicked flees when no one pursues him; but the righteous is bold as a lion" (Proverbs 28: 1). The object of the theopsychological study of stress in the article is the reaction of the human spirit and soul to the historical changes of the spiritual and moral atmosphere and of man himself, from Creation, through knowledge of the law of sin and death to the present day. The set natural defense mechanisms as a response to stress are: rationalization, projection, repression, identification, compensation, hypercompensation, fantasizing, dominant ideas. They have advantages and disadvantages, which is why in our study we seek to focus on conscious psycho-spiritual defense mechanisms, shown in personalities described in the Bible.<br/><br/>Description: Статията застъпва тезата, че всяко изследване на стреса само на психическо и физическо ниво е лишено от пълнота. Последните изследвания в медицината и психологията допълват анализа, но не са достатъчни за формулиране на работещи решения. Съществуват пет направления в изучаването на стресови реакции: биологично, медицинско, психологично, социално-психологично, към които в този текст добавяме и тео-психологично. Стресът има дълбоки психофизиологични и психодуховни корени, въпреки, че едва в последното столетие за неговото влияние, причини и резултати заговориха психолози, медици и педагози. Авторът разглежда историята на стреса от богословска перспектива, с фокус върху неговото духовно измерение. Като се изхожда от наличните психодуховни външни и вътрешни стресогенни фактори, стресът се дефинира като комплексна ответна реакция на човека на външни и вътрешни дразнители, които предизвикват напрежение и потрес в духа, душата и тялото на човека. От момента на прекъсването на отношенията с Бога, на подсъзнателно ниво в човека постоянно присъства чуство на вина, страх от неочаквана и неизвестна опасност. Тази психодуховна фиксация се задейства при екстремални ситуация, предизвикани от външни дразнители, като причината е липса на опора, увереност на духовно, психическо и физическо ниво. Обект на теопсихологическото изследване на стреса в статията е реакцията на човешките дух и душа спрямо историческите изменения на духовно-нравствената атмосфера и на самия човек, от Сътворението, през познаването на закона на греха и смъртта до днес. Заложените природни защитни механизми като ответна реакция на стреса са: рационализация, проекция, изтласкване, идентификация, компенсация, хиперкомпенсация, фантазиране, доминиращи идеи. Те имат предимства и недостатъци, поради което в нашето изследване търсим се фокусираме на осъзнати психодуховни защитни механизми, показани в личности, описани в Библията.The West Reads the South-East: (in)Gratitude in Catholic and Orthodox Political Theologies

Title: The West Reads the South-East: (in)Gratitude in Catholic and Orthodox Political Theologies<br/><br/>Authors: Telarico, Fabio Ashtar<br/><br/>Abstract: This paper deals with the role of gratitudue in Catholicism’s political theology in search for an equivalent in the power relations involving the Bulgarian and Serbian Orthodox Churches through the cults of Ivan Rilski and the canonised monk Sava. To do so, it analyses Medieval West Europe’s theology of gratitude starting from Marsilius of Padua’s Defensor Pacis (1324). The text concludes that Marsilius’s criticism have little pertinence to South-East Europe for both theological and political reason, paving the way to a better mutual understanding of Eastern and Western European histories and culture.3D Printing in Education – Innovative Approaches to Learning through Modern 3D Technologies

Title: Mathematical Model of Forest Fire and Its Relationship with Simulations and Serious Games (SSG)<br/><br/>Authors: Ikonomov, Nikolay<br/><br/>Abstract: Forest fires are readily available, but data is not. We present our abstract mathematical model of a forest fire in Bulgaria, without any real-world data. Our main thesis is that it looks realistic. Our calibration techniques are limited to integer values, with a hint of real numbers. Our visualization technique is fixed function pipeline OpenGL implementation, but it does the job. Our programmer staff is limited to two people, both experts in their fields, that managed to make two distinct software products, that have as a base the same solid mathematical algorithm.Student Attitudes Toward Basic Characteristics of Mobile Learning
