The paper reports the result of a 2-year long research conducted by CTBUH on the design possibilities enabled by the Ropeless and Multidirectional elevator systems, investigating how such a significant innovation (or better to say revolution) in the vertical transportation could affect tall buildings first and cities then. The purpose of the study is to prefigure the adoption of ropeless and multidirectional cabins for tall buildings mobility, with the aim to overcome the evolutionary bottleneck of the high-rise building type due to the exclusively vertical direction of transport, which limited, over the years, the design possibilities in terms of height, shape and relations with the surrounding environment. CTBUH research team, together with professionals in the field and supporting academic advisors, developed a series of design considerations on plan organizations, dispatching alternatives and on the integration of horizontal direction in the circulation, with the aim of anticipating potential and criticality arising from the application of ropeless and multidirectional systems.

The purpose of this study is to examine the principles of clothing design and the way of design approach in Lamanova. She caused a revolution in the art of dress and created the foundation for costume design theory. She Addressed Art in everyday life to self-taught dressmakers. The distinguishing feature of the design is simplicity and functionality. In an article "The Russian Style", Lamanova raised the question of the new Soviet costume and traditional costume. In "On Contemporary Costume" she classified the new forms of clothes into everyday and holiday attire, showed the principles of costume, and analyzed in detail the necessity of constructing a costume to suit the individual figure. In "On the Rationality of Costume", she found a basis theory for clothing design which is for whom, from what, and for what purpose. Lamanova's theory was made public in full in 1928 and was presented at the exhibition of Handmade Textiles and Embroidery in Women's Contemporary Costume. The main contents are the costume's purpose, it's material, the figure of its wearer, and its form. She argued that the new costume could be in line with the new life and her theory could be the creed of clothing designers. The principles of Lamanova's theory can still be applied today, not only in Russian traditional and contemporary costume, but in contemporary world fashion.

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.

The Fourth Industrial Revolution, centered on intelligence and information, began to take hold in 2016. This study uses virtual reality technology, which is the most popular technology of the Fourth Industrial Revolution. The purpose of this study is to explore a Virtual Walk-through method, which can be easily applied to landscape architecture. At present, virtual reality technology is widely used in the fields of games, emergency training, and architectural design. However, in the field of landscape architecture, it is still in the development stage. In addition, most of the traditional ways to display virtual reality use 2D images, but such methods have some limitations. Therefore, this research addresses the three stages of "design-exhibition-experience" and puts forward a new simple method called 'Virtual Walk-through' that breaks from traditional landscape design exhibitions. The results show that compared with traditional methods, virtual reality has many advantages, such as the freedom of experience, a diversity of viewing angles, information supply, interaction, etc. It can show high quality images and effects, which are suitable for landscape design. It provides an evaluation method for garden design that can be utilized in the future. It is simple and has value as it can reflect the method and the expected effects. Virtual reality technology can bring an infinite number of prospects to the development of landscape architecture.

This study will focus on research and analysis covering the period of time since the creation of the People's Republic of China to current day China, with an emphasis on 20-something year-old women living in Shanghai. In conducting this research, historical evidence of fashion was derived from books, photographs, and Internet resources pertaining to the specific periods of interest. Furthermore, each set of data has been organized in approximately decade-long segments that best reflect the transformation of Chinese fashion from 1949 to 2000. As a result of the countrywide emphasis placed on revitalization of the newly created Chinese state during the period of 1949 to 1965, detail to fashion was largely ignored, in preference to the successful upstart of a working economic foundation. This neglect of fashion is evident by the scarcity of new and daring styles during this period. The following the period of 1966 to 1977 ushered in a cultural revolution that was aptly demonstrated in the changing fashion tastes. When compared with the previous period, the blandness of clothing, authorized by the Chinese government clearly reflected the rules and regulations strictly enforced by a government mandate of conformity and obedience. These orthodox changes were so drastic, that women wearing these clothes could hardly be differentiated from men in the same style wear. After Mao Ze Dong's death in 1976 and the end of the sternest period of the Chinese Revolution, a new era of Chinese culture and fashion was made possible by a more lax and tolerant government. During the later palt of the seventies through the eighties, this new governmental policy fostered more openness and self-expression, both of which led to a newfound interest in expressing one's desires and personality through the clothes he or she chose to wear.

Since the 18th century the museums in Europe have accepted the social demand of the publicity and have played a role of social education and it lasted to the present. Recently, the society began to change it's direction. It is from the Universalism to the Pluralism. The Universalism is due to democratic society after 'the Civil Revolution' and standardized social system after 'the Industrial Revolution' The Pluralism that starts with the decrease of the modern society is about the diversity and the activation of identity which has been disregarded since the Modernism. This study is to analyze and to clarify how the museum's educational environment which had begun since the 18th century has been changed since 1990 and how these are related to the social alteration from the Universalism to the Pluralism. As a result of this study, it was confirmed that there had been a simple circulation system and a unified spatial experience in the museum of Europe since 18th century to 1980's(phl) while there had been a complex circulation system and a diverse spatial experience in the museum of Europe after 1990's(ph2). These mean that the museum of phl gave a unified social education to the visitors and they came to have a similar knowledge and emotion after their seeing the exhibition material while the museums of 'ph2' gave a diverse one and the visitor came to have a different knowledge and emotion to the same exhibition material. The museum which gives a unified social education is to produce a unified thoughts of people and it is because the social direction is the Universalism. In addition to this, the museum of diverse social education is to produce people of diversity and it is related to the Pluralism.

Nowadays, Korean consumers prefer drum-type washing machines to pulsator-type washers. Washing is a complex process involving the interaction of numerous physical and chemical influences. The main factors in the washing operations are the washing chemistry of the detergent along with the mechanical input, the wash temperature, and the time provided by the washing machine. Heavy-duty detergents that are used in drum-type washing machines contain different components from those used in vertical-axis washing machines. The bath ratio and the mechanical actions to which laundry is subjected are different between the drum-type and the vertical-axis washing machines. In this study we examined the effects of wash temperature, wash time, detergent concentration, and revolution speed on the removal of soils from artificially soiled cloths in a drum-type washing machine with heavy-duty commercial detergent. We used multiple regression analyses to find the relative importance of the factors and the optimum washing conditions. The results of these experiments showed that the washing temperature was the most important factor in the effective removal of most soils. This was followed by the washing time, the detergent concentration, and finally the revolution speed. In this study it was found that superfluous amounts of detergent did not sufficiently increase the soil removal rate. Koreans who are used to washing with cold water should increase the wash time to launder more efficiently.
