  • This paper presents a state-of-the-art review on the design, research and education aspects of fire safety engineering (FSE) with a particular concern on high-rise buildings. FSE finds its root after Great Fire of Rome in 64 AD, followed by Great London Fire in 1666. The development of modern FSE is continuously driven by industry revolution, insurance community and government regulations. Now FSE has become a unique engineering discipline and is moving towards performance-based design since 1990s. The performance-based fire safety design (PBFSD) involves identification of fire safety goals, design objectives, establishment of performance criteria, and selection of proper solutions for fire safety. The determination of fire scenarios and design fires have now become major contents for PBFSD. To experience a rapid and positive evolution in design and research consistent with other engineering disciplines, it is important for fire safety engineering as a profession to set up a special educational system to deliver the next-generation fire safety engineers. High-rise buildings have their unique fire safety issues such as rapid fire and smoke spread, extended evacuation time, longer fire duration, mixed occupancies, etc., bringing more difficulties in ensuring life safety and protection of property and environment. A list of recommendations is proposed to improve the fire safety of high-rise buildings. In addition, some source information for specific knowledge and information on FSE is provided in Appendix.

  • High-rise buildings with vertical setback are widely used in practice. From the field investigation of the past earthquakes, it was found that such kind of vertically irregular high-rise building structures easily suffer severe damage during strong earthquakes. This paper presents an extensive study on the earthquake responses of moment-resisting frame structures (MFS) popularly applied in high-rise buildings with vertical setback. Four groups of MFS are designed, including three groups of structures with vertical setback and one group of structures with the lateral stiffness varying along the building height but without vertical setback. The numerical models of the structures are established, and the time history analysis of the structures under different levels of earthquakes is conducted. The earthquake responses of the structures are compared. The influence of the ratio between the horizontal setback dimension and the previous plan dimension, the eccentricity of setback, and the position where the setback occurs on the seismic performance of structures is studied. The rationality of the provisions for the structures with vertical setback specified in the current design codes is checked by the findings from this study.

  • The article clarifies the conditions for information, digital and educational accessibility for higher education seekers with disabilities in terms of distance learning caused by quarantine restrictions. It is established that such conditions are regulated by international and Ukrainian legal documents (The Standard Rules on the Equalization of Opportunities for Persons with Disabilities, Convention on the Rights of Persons with Disabilities, Sustainable Development Goals, Law of Ukraine "On Education", Law of Ukraine "On Higher Education", Strategy for the Development of Higher Education in Ukraine 2021-2031, Development Strategy areas of innovation for the period up to 2030, Development strategy of the sphere of innovation activity for the period up to 2030). As a part of information barrierlessness, Higher Education Institutions (HEI) should provide access to information in various formats and using technologies, in particular Braille script, large-type printing, audio description (audio descriptive commenting), sign language interpretation, subtitling, a format suitable for reading by screen access programs, formats of simple speech, easy-to-read formats, means of alternative communication. The experience of Pavlo Tychyna Uman State Pedagogical University is described. In particular, special attention is paid to the study of sign language: in view of this, the initiative group implemented the project "Learning to hear and overcome social isolation together" with the financial support of the British Council in Ukraine. Within the framework of digital accessibility, the official website of the Faculty of Social and Psychological Education has been adapted for the visually impaired in accordance with WCAG 2.0 World Standards. In 2021, Pavlo Tychyna Uman State Pedagogical University implemented the project "Cultural, Recreational and Tourist Cherkasy Region: Inclusive Social 3D Map" funded by the Ukrainian Cultural Foundation; a site with available content for online travel in the region to provide barrier-free access to the historical and cultural heritage of Cherkasy region was created. Educational accessibility is achieved by increasing the number of people with special educational needs, receiving education in inclusive groups; activities of the Center for Social and Educational Integration and Inclusive Rehabilitation Social Tourism "Bez barieriv" ("Without barriers"); implementation of a research topic for financing the Ministry of Education and Science of Ukraine: "Social and psychological rehabilitation of children and youth with special educational needs by means of inclusive tourism"; implementation of the project "Social inclusion of distance educational process"; development of information campaigns to popularize the ideas of accessibility, the need for its implementation, ongoing training programs and competitions, etc.

  • High-rise buildings are increasingly viewed as having both technical and economic advantages, especially in areas of high population density. Increasingly taller buildings are being built worldwide. Increased heights entail increasing flexibility, which can result in serviceability problems associated with significant displacements and accelerations at higher floors. The purpose of this paper is to present the concept of a versatile vibration control technology (MR dampers with bracings) that can be used in super tall buildings. The proposed technology is shown to be effective, from a serviceability point of view, as well as resulting in dramatically reduced design wind loads, thus creating more resilient and sustainable buildings.

  • We have various understandings regarding health. Various medical systems being practiced in India other than conventional medicine i.e. Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy have defined health in their own way. From physical level up to spiritual level health has so many aspects which affect our overall personality. Some says that one who is established in self is healthy but some other says that in a perfect state of health physical homeostasis and mental equanimity occur in a balanced and healthy harmony. Another concept believes that health is normal and harmonious vibration of the elements and forces composing the human entity on the physical, mental, moral and spiritual planes of living in accordance with the constructive principles in Nature. At one place it is stated that good health means existence in harmony with evolution. The authors have reviewed various concepts and definitions of health and trying to conclude that health is a feeling which may be experienced only if you are really healthy. So, health is more and more balancing of all elements of your life in harmony with the universe.

  • An extracellular limonoate dehydrogenase was purified 10-fold from a cell-free extract of Rhodococcus fascians by ammonium sulfate precipitation, dialysis, and ultrafiltration. This purified dehydrogenase catalyzed the conversion of limonoate to 17-dehydrolimonoate. The enzyme showed optimum activity at pH 8.0 and $40^{\circ}C$, with $K_m$ value of 0.9$\muM$, and requires Zn ions and sulfhydryl groups for catalytic action. The enzyme activity was inhibited by $Hg^{2+}\;and\;NaN_3$ ions. The degradation of limonin (66%) in Kinnow mandarin juice was successfully demonstrated with partially purified limonoate dehydrogenase. With scale-up preparation of limonoate dehydrogenase, a successful debittering operation of fruit juices appears feasible.

  • For an $m{\times}n$ nonnegative integral matrix A, a generalized inverse of A is an $n{\times}m$ nonnegative integral matrix G satisfying AGA = A. In this paper, we characterize nonnegative integral matrices having generalized inverses using the structure of nonnegative integral idempotent matrices. We also define a space decomposition of a nonnegative integral matrix, and prove that a nonnegative integral matrix has a generalized inverse if and only if it has a space decomposition. Using this decomposition, we characterize nonnegative integral matrices having reflexive generalized inverses. And we obtain conditions to have various types of generalized inverses.

  • This study was designed to determine the level of nutrition knowledge of 3,390 elementary school children in Seoul and Kangnung, and to examine the relationship of demographic characteristics of children to nutrition knowledge. Nutrition knowledge was measured by modified NATs (Nutrition Achievement Tests developed by National Dairy Council and Iowa State University). Higher nutrition knowledge, correlated with increasing parental educational level, lower parental age, and higher socioeconomic status. However, there was no difference in total test scores between children in Seoul and Kangnung. Item scores indicated children had more knowledge about 'physiological facts' and 'food handling', and limited knowledge about 'nutrients' and 'nutrition and society'. Children, both in Seoul and Kangnung, lacked an undestanding of many basic principles of nutrition. These results suggest several areas to emphasize when developing nutrition education materials. Modified NATs in this study may be used to assess nutrition education needs of children, to evaluate the effectiveness of nutrition education program, and to compare nutrition achievement of different groups.

  • Doping of boron atoms in graphite has been well known method to increase the discharge capacity as the negative electrode material for lithium secondary battery. Herein, the boron-doped graphites are prepared by mixing 1, 2.5, 5, and 7 wt. % of boron carbide in carbon during the graphitizing process. The structural states of boron in boron-doped graphites are investigated by solid-state 11B NMR spectroscopy. The resonance lines for substitutional boron atoms are identified as the second order quadrupolar powder pattern with the quardrupole coupling constant, QCC = 3.36(2) MHz. The quantitative analysis of 11B NMR spectra with boron-doped graphite has also been performed via simulation.

  • When Cole Porter wrote the song "Anything Goes" in 1934, he did not include skyscraper examples. The recently completed Chrysler and Empire State buildings followed decades of tall building development in a logical and predictable line. Today, dramatic improvements in materials and methods of analysis, design and fabrication have given architects and engineers freedom to imagine, and contractors to build, towers in configurations never seen before. If writing now, Porter would surely have mentioned such designs to demonstrate anything goes. Or does it? This article explores the possibilities and challenges of tall building structural design through current and proposed projects. Examples include engineering buildings with outward forms that appear structurally unfavorable and taking advantage of load reduction through shaping opportunities.
