Formerly, it was called a tent and now, it is called membrane structure. If saying a tent, it imagines the tent of Bedouin, Mongolia and North American Indian. It became clear from the excavated wall painting that have been covered with the retractable roof of the canvas on the auditorium at the amphitheater in Pompeii and became a topic. These tents were made of the animal skins or fabric woven with the flax plants, and these tents are still used. However, if saying membrane material at present, it says the one to have applied a coating resin to the textile. Because the base fabric of membrane material is a woven fabric, the relation between the stress and the strain is different to the direction of the weaving thread. Moreover, the tensile force must always occur in the membrane surface. From these reasons, because the membrane structure corresponds to the particular building material and the construction method about the Building Standard Law, it must be examined specially that the membrane structural building have the same or any more safety as the provisions which was set to the Building Standard Law. Therefore, the technical standards about the membrane structural building became indispensable. In the paper, the kinds of the membrane materials, which are used for the membrane structural buildings, and technical standards process of the creating for the membrane structure buildings are introduced. Lastly, some of the soccer stadiums for 2002 FIFA World Cup KOREA/JAPAN which be covered with the roof of the membrane structures are presented.

The french modernist garden of the 1920-30s, significant when studying the history of gardens, has been disregarded in landscape architecture studies. This study aims to review and examine the main characteristics of the French modernist garden in relation to Cubism. In addition this study seeks to recover an unnoticed phase from landscape architecture history and lies in a same thread with studies on the theory of Modernism in landscape architecture. The french modernist garden is closely connected with Cubism, as Cubist garden is a popular synonym for the French modernist garden. used simplified and geometrical forms like Cubist painters. In spacial composition, the French modernist garden offered images of various views in one space, much like the Cubist paintings which showed various aspects of an object simultaneously on the canvas. In the French modernist garden, gorgeous colors and various textures were emphasized, much like the synthetic Cubism. Moreover, in the history of landscape architecture, the state of the French modernist garden which tried to change the traditional gardens into a space more suited to the new life style, is similar to that of Cubism as an art movement in the history of art of the early 20th century.

The purpose of the present study is to identify the drying cylinder model in paper plants and to analyze characteristics of process responses for changes in input variables. The model developed in this work is based on actual plant operation data where the steam pressure applied to the cylinder behaves as the major variable. It is found that heat transfer coefficients from the condensate to the canvas could be represented as empirical relations based on heat conductivities and operation data. The effectiveness of the cylinder model is demonstrated by the measured moisture contents and web temperature. Stability of the drying process is analyzed based on the transfer functions derived from the cylinder model.

This paper presents the design and implementation of virtual aquarium by generating 3D models of fishes that are colored by viewers in an aim to create interaction among viewers and aquarium. The virtual aquarium system is composed of multiple texture extraction modules, a single interface module and a single display module. The texture extraction module recognize the QR code on the canvas to get information of the predefined mapping table and then extract the texture data for the corresponding 3D model. The scanned image is segmented and warp transformed onto the texture image by using the mapping information. The extracted texture is transferred to the interface module to save on the server computer and the interface module sends the fish code and texture information to the display module. The display module generates a fish on the virtual aquarium by using predefined 3D model with the transmitted texture. The fishes on the virtual aquarium have three different swimming methods: self-swimming, autonomous swimming, and leader-following swimming. The three different swimming methods are discussed in this paper. The future study will be the implementation of virtual aquarium based on storytelling to further increase interactions with the viewer.

Oil painting shows a wide variety of damages due to differentcohesiveness between materials and different responses to temperature and humidity. The deforming flatness of canvas is a major cause of deterioration. The heat, pressure and moisture, and classical materials which had been traditionally used to correct the deformation of supports have caused damages to the paintings. In modern restoration of paintings, new methods have been developed to avoid the use of such potentially harmful elements. In this paper the correcting of deformed support with the use of low-pressure table, deformation correction frame and new materials, which has been developed both to protect the works and to maximize the effect of restoration.

This article was written in order to understand rockers of today and to provide basic data of their designs and manufacture studying pattern changes in the West. This article contains, the characteristics of the style of the Adirondack rockers, the Mission style rockers in America and the European rockers. Adirondack rockers ($1850{\sim}1940$) were made in various styles out of the mingling of rustic sensibilities with the formalism of Victorian designs. They were Old Hickory chair Co. style, Westport style, bentwood rocker style of two shape and Mottville rocker style. Mission style denoted American furniture design style of the early 20th century especially the work of Gustav Stickley and Roycroft Community. Mission style rockers had a simple, rectilinear style with exposed construction techniques, unpretentious materials (usually oak, with covering of leather, canvas or plain cloth) and little or no decoration. European rockers ($1660{\sim}1918$) have come to mean rockers from the English regional chair, Thonet, J&J Kohn, Henry Van de Velde and Hoffmann. The modernism of modern furniture was affected by the characteristics of the Adirondack rockers, the Mission style rockers and European rockers.

The subject of this study is to find out the characteristics of spacial expression in 'Le Carceri' of Giovannibattista Piranesi. Piranesi was the classicist from using classical motif. But for using itself he was not absolute canon of classical but playing tool. Because his etchings of perspective were presented the modernity not fixed the frame. The etchings of Le Carceri were characterized the dark, deep, heavy and devastating. In conclusion, the characteristics of spacial composition in his etchings were presented the simultaneity of time both classic and contemporary time. And it could represented the nonexistent of structurality for visual rationality. Architectural & de-architectural elements of his drawing were become in fragments. So the fragmented elements, his etchings have shawn the off-center to cast off the classical concept. And also the body of human was become the thing of object in his drawing. That is, it was inverted the subject and the object and the function of prison depicted in canvas is disappeared. This is the point of evocation in Piranesi' idea.

Due to COVID19 pandemic, most of educational institutions and schools changed the traditional way of teaching to online teaching and learning using well-known Learning Management Systems (LMS) such as Moodle, Canvas, Blackboard, etc. Accordingly, LMS started to generate a large data related to students' characteristics and achievements and other course-related information. This makes it difficult to teachers to monitor students' behaviour and performance. Therefore, a need to support teachers with a tool alerting student who might be in risk based on their recorded activities and achievements in adopted LMS in the school. This paper focuses on the benefits of using recorded data in LMS platforms, specifically Moodle, to predict students' performance by analysing their behavioural data and engagement activities using data mining techniques. As part of the overall process, this study encountered the task of extracting and selecting relevant data features for predicting performance, along with designing the framework and choosing appropriate machine learning techniques. The collected data underwent pre-processing operations to remove random partitions, empty values, duplicates, and code the data. Different machine learning techniques, including k-NN, TREE, Ensembled Tree, SVM, and MLPNNs were applied to the processed data. The results showed that the MLPNNs technique outperformed other classification techniques, achieving a classification accuracy of 93%, while SVM and k-NN achieved 90% and 87% respectively. This indicates the possibility for future research to investigate incorporating other neural network methods for categorizing students using data from LMS.

The prefix 'bio' with the meaning of 'life,' has been used for biotechnology, biochemistry, bioengineering, biomedicine, bioethics, bio-information as well as 'bio art' since 1990s. Bio art is an art as life itself and a kind of new direction in contemporary art that manipulates the processes of life. Bio artists use the properties of life and materials as scientists in laboratory of biology, and change organisms within their own species, of invents life with new characteristics. Technologically and socio-culturally, bio art has been connected with bioengineering. This essay is on the bio art that use vegetables, and on the specified gaze of so-called 'Sci-Artists.' Not only the genetically modified vegetables like works of George Gessert, Ackroyd & Harvey, and Eduardo Kac, but also the works made from the critical viewpoint like those of Paul Vanouse, Natalie Jeremijenko, and Amy Youngs, have 'the molecular gaze'(Suzanne Anker and Dorothy Nelkin's concept) of the genetic age in their art works. As the art history have showed, artists' gazes have insights about social problems that surround us. Bioartists' gazes reveal their insights about social and ethical problems, possibly concealed by science itself. Those problems are about results from practical discoveries of the sequencing of the genome, genetic engineering, cloning and reproduction of human and animals, body transformation, and the commercialization of cell and genes etc. We can find the significance of bioart in the molecular gaze about those problems, and we can rethink the identity of human, the reception of social influences from bio-technology and medicine.
