Effective Use

Building Information Modelling (BIM) is a complex process of managing not only design documentation in 3D form but it also includes all the consecutive stages of the design analysis, followed by construction management, and including facility management after the site completion. The success in the collaboration to unite common efforts of architects, constructors and HVAC engineers would make the work of all involved stakeholders more productive because the existing information technologies provide this option already for a long time. The training for effective use of this relatively new and very complex approach from the very beginning of the building lifecycle in the construction industry is even a more complex task. Universities have to join the promotion of BIM ideas not only to the designers and engineers, but to a much wider public than at present. The history of BIM teaching and the approaches used at Riga Technical University (RTU) are outlined in this paper. RTU along with several other universities from Lithuania have joined the EU sponsored Leonardo da Vinci project BIMTRAIN initiated by regional software distributer and developer AGA-CAD which facilitates the BIM implementation through the training.

In recent years, many efforts have been invested in the cultural heritage digitization: surveying, modelling, diagnostic analysis and historic data collection. Nowadays, this effort is finalized in many cases towards historical building information modelling (HBIM). However, the architecture, engineering, construction and facility management (AEC-FM) domain is very fragmented and many experts operating with different data types and models are involved in HBIM projects. This prevents effective communication and sharing of the results not only among different professionals but also among different projects. Semantic web tools may significantly contribute in facilitating sharing, connection and integration of data provided in different domains and projects. The paper describes this aspect specifically focusing on managing the information and models acquired on the case of vaulted systems. Information is collected within a semantic based hub platform to perform cross correlation. Such functionality allows the reconstructing of the rich history of the construction techniques and skilled workers across Europe. To this purpose an ontology-based vaults database has been undertaken and an example of its implementation is presented. The developed ontology-based vaults database is a database that makes uses of a set of ontologies to effectively combine data and information from multiple heterogeneous sources. The defined ontologies provide a high-level schema of a data source and provides a vocabulary for user queries.

The role of monetary factor in generating inflationary processes in Russia has stimulated various debates in social and scientific circles for a relatively long time. The authors show that identification of the specificity of relationship between money and inflation requires a complex approach based on statistical modeling and involving a wide range of indicators relevant for the price changes in the economy. As a result a model of inflation for Russia implying the decomposition of inflation dynamics into demand-side and supply-side factors is suggested. The main conclusion drawn is that during the recent years the volume of inflationary pressures in the Russian economy has been determined by the deviation of money supply from money demand, rather than by money supply alone. At the same time, monetary factor has a long-run spread over time impact on inflation.

Introduction. The organization of transport links and the bridge building in cities located on the banks of wide rivers has always been one of the most important tasks of the local administration. The study of the history of bridge building allows not only to trace the process of modernization of different regions of the country, but also to help in solving similar problems of our time. Nevertheless, the history of Russian bridge building is poorly studied. The purpose of the article is to determine the characteristics and features of the organization of bridge building in big cities of the European North of Russia as a way to solve one of the problems of urban infrastructure in the early XX century. Materials and Methods. The sources for this study are the documents of the State archive of the Arkhangelsk region, published documents on the history of Vologda, articles in the local periodicals of the early XX century. The analysis of the studied problem used a systematic approach, the method of economic analysis, historical and historical-comparative methods. Results and Discussion. The building of permanent bridges was a need for the development of Arkhangelsk and Vologda. In Vologda the two wooden bridges were built in the middle of XIX century on city funds and in the future these bridges were repaired or rebuilt. The Arkhangelsk city authorities did not hurry to solve a problem of city infrastructure by own efforts and a long time they used the floating bridge. The lack of experience in the building of large bridges and the desire to save money led to the rapid destruction of the first permanent bridge in Arkhangelsk. Conclusion. The Development of trade and industry in cities of the European North of Russia, such as Arkhangelsk and Vologda, led to the expansion of their territory and the emergence over time, the so-called third parts of the cities. Despite the comparable size of the population of the districts located across the river, the process of connecting them with bridges to the rest of the city went at different rates, which depended on the attitude of the local administration to the problem of urban infrastructure.

شهد تاريخ الأمة الإسلامية حضارة ونهضة عالمية في جميع مجالات الحياة الإنسانية، ومما كان له كبير الأثر في ذلك هو الأوقاف التي بدأت مع سيد البشرية محمد صلى الله عليه وسلم واستمرت بتنوع وشمولية إلى عصرنا الحالي؛ ولكن ما تعرضت إليه الأوقاف من إهمال وإقصاء وضياع يرجع لأسباب عديدة من أهمها غياب التوثيق الوقفي. تقوم الدراسة على تتبع مفهوم الوقف والتوثيق، والوقف في الإمارات العربية المتحدة ول سيما في إمارة الشارقة. توصلت الدراسة إلى نتائج منها: أن الأوقاف قائمة منذ زمن بعيد، وأن رغبة الواقف بالوقف وإقدامه عليها لم ينقصها سوى وثيقة، وأنه لا وثائق لها ولا مستندات، كما أن العرض الموجز لنشأة دائرة الأوقاف بالشارقة وسعيها لإحياء سنة الوقف ونشر ثقافته نراه يتضح شيئاً فشيئاً من خلال تفعيل مواد القانون والبحث حول الأنسب والأصح لحماية الأوقاف، ولم يكن هذا الاهتمام بالوقف إلا انعكاساً لتوجه الواقفين وتماشياً لرؤية الحكام وامتثالاً لنهج خير الأنام ورغبة في تكافل الأرواح وحباً للسلام. الكلمات المفتاحيّة: الوقف، التوثيق، المقارنة، الشارقة. Abstract The history of Islamic nation has witnessed a global civilization and it has had a great impact in all areas of human life, including the endowments that began with the master of humankind; Muhammad S.A.W. and it was continuing in diversity and comprehensively until our epoch. However, there are some problems related to endowment management such as negligence, exclusion and loss that due to many reasons. Among the most important reasons is the absence of endowment documentations. Therefore, the study aims to discuss the concept of endowment and documentation, as well as the endowment in United Arabic Emirates, especially in the Emirate of Sharjah. The study concluded that the practice of endowment has been existed for a long time, yet there are in need of endowment documentations. This study also found that the information related to the establishment of institution of endowment in Sharjah and its role has   spread widely to the people through the enforcement of the law and the implementation of the research related to the practice of endowment in order to sustain them in a good way. This documentation system was only a reflection of what has  stated in Shariah laws regarding the practice of endowment among the donors, so that it will be in line with the approach of good intentions and love of peace.

At the present stage, Kazakh musical culture is heterogeneous. It represents traditions coexisting at the same time and interacting with each other: Kazakh ethnic and newly established composer school (tradition). Examining changes in cultural landscapes of the 20th century I reveal the peculiarities of interaction and dialogue between two kinds of culture: ethnic and global (endogenous and exogenous). The procedures include the complex study of the history of Kazakh culture in the 20th century, stylistic analysis of traditional and composer’s music, semiotic approach to intercultural interaction, as far as a comparative analysis of oral and written music of 19th and 20th centuries. On one hand, dramatic changes in the structure of music culture were caused by external objective reasons: new industrial and postindustrial civilization phases (urbanization and information technologies); intensification of interaction with western (mainly Russian) cultures, etc. On the other hand, some changes were inspired by inner factors: diverse development of local song and kui (dombyra piece) traditions; Soviet cultural policy. As a result new type (or layer) of national culture – Kazakh composers’ music – appeared. It was connected with the formation of a national style based on transcriptions and borrowing. Traditional music was influenced by new social institutions (philharmonic halls, theatres, radio, conservatoire) that caused changes in the creative process (decrease of oral transmission, lack of traditional social context) as well as in the style (virtuoso performance, new genres of songs).

вопросы взаимодействия моды и сферы искусства, аспекты сближения их позиций в области репрезентации базовых эстетических установок конца XIX – начала XX вв. долгое время оставались вне поля исследовательского внимания культурологов и искусствоведов. Между тем, для преподавания курса мировой художественной культуры (МХК) анализ динамики взаимопроникновения моды и искусства в период модерна, выявление параллелей в развитии фэшн-трендов и художественных направлений конца XIX – начала ХХ в. имеет принципиальное значение. Обосновать необходимость включения учебного материала по вестиментарным фэшн-трендам в курс МХК – наша задача. questions of interaction between fashion and art, aspects of convergence of their positions in the field of representation of basic aesthetic attitudes of the late XIX – early XX centuries for a long time remained out of the field of attention of researchers. Meanwhile, for teaching the history of world culture, the analysis of the dynamics of the interpenetration of fashion and art in the modern period, the identification of parallels in the development of fashion trends and artistic trends of the late XIX – early XX century is of fundamental importance. Our task is to justify the need to include educational material on vestigial fashion trends in the course of world art culture.

In recent years, the use of digital twins (DT) to improve maintenance procedures has increased in various industrial sectors (e.g., manufacturing, energy industry, aerospace) but is more limited in the construction industry. However, the operation and maintenance (O&M) phase of a building’s life cycle is the most expensive. Smart buildings already use BIM (Building Information Modeling) for facility management, but they lack the predictive capabilities of DT. On the other hand, the use of extended reality (XR) technologies to improve maintenance operations has been a major topic of academic research in recent years, both through data display and remote collaboration. In this context, this paper focuses on reviewing projects using a combination of these technologies to improve maintenance operations in smart buildings. This review uses a combination of at least three of the terms “Digital Twin”, “Maintenance”, “BIM” and “Extended Reality”. Results show how a BIM can be used to create a DT and how this DT use combined with XR technologies can improve maintenance operations in a smart building. This paper also highlights the challenges for the correct implementation of a BIM-based DT combined with XR devices. An example of use is also proposed using a diagram of the possible interactions between the user, the DT and the application framework during maintenance operations.

Neurofibroma is a rare nerve sheath tumor of neuroectodermal origin, especially the huge and isolated neurofibroma located in the inguinal region. To our knowledge, no such case has previously been reported. We report a case of 34-year-old male patient with a 4-year history of progressive enlargement of the medial root mass in his left thigh with sitting and standing disorders along with pain. The tumor was completely removed by operation, and pathological diagnosis showed neurofibroma. There was no obvious neurologic defect after surgery, and no recurrence tendency was found in the follow-up of 2 years. For a large solitary mass with slow growth and no malignant clinical manifestations for a long time, clinicians cannot rule out the hypothetical diagnosis of neurofibroma, even though its growth site is very rare, such as this case of a huge tumor located in the groin. For neurogenic tumors, early operation should be performed, and the prognosis of patients after tumor resection is excellent.

The Impact

Recent years have witnessed an increase in the number of academic studies on the impact of technological advancements on human life, including possible transformations and changes in human sexuality following the development of sex-related devices, such as sex robots. In this context, terms such as posthuman sexuality, digisexuality, and techno-sexuality have emerged, signaling possible new understandings of sexual, intimacy, and emotional practices. It is important to note that ancient history shows that humankind has for a long time been fascinated with their relationship to non-living things, mostly human-like figures, such as dolls. The Ningyo (人形, the Japanese term for doll) has a long history of usage, and has deep religious and animistic significance in the Japanese context—there are records of sexual use as early as the 18th century. With this context in mind, this paper focuses on three Japanese examples, aiming to shine a light on beyond-human relationships, which include a Japanese man’s marriage to a digital character, sex dolls, and communicative robots, from both a sexual and emotional perspective. In a new horizon of sexual and romantic possibilities, how will humans respond, and what can emerge from these interactions?

Mitochondrial biogenesis is a complex process. It necessitates the contribution of both the nuclear and the mitochondrial genomes and therefore crosstalk between the nucleus and mitochondria. It is now well established that cellular mitochondrial content can vary according to a number of stimuli and physiological states in eukaryotes. The knowledge of the actors and signals regulating the mitochondrial biogenesis is thus of high importance. The cellular redox state has been considered for a long time as a key element in the regulation of various processes. In this paper, we report the involvement of the oxidative stress in the regulation of some actors of mitochondrial biogenesis.
