Structures consisting of concrete and steel parts, which are irregular in damping ratios are investigated. This investigation is a code-based seismic design of such structures. Several practical difficulties encountered, due to inherent differences in the nature of dynamic response of each part, and the different damping ratios of the two parts. These structures are irregular in damping ratios and have complex modes of vibration so that their analysis cannot be handled with the readily available commercial software. Therefore, this work aims to provide simple yet sufficiently accurate constant values of equivalent damping ratios applied to the whole structure for handling the damping irregularity of such structures. The results show that the equivalent damping ratio changes with the height of the building and the kind of the structural system, but it is constant for all accelerations values. Thus, available software SAP2000 applied for seismic analysis, design and the provisions of existing seismic codes. Finally, evaluation of different kinds of structural system used in this research to find the most energy dissipating one found by finding the best value of quality coefficient.

This study considers the expressive types of 'Glocalism' trends and its inherent aesthetic characteristics through the analysis of flight attendants' uniform design. The following is the conclusions regarding the glocalism trend according to the analysis of airline uniform design that reflect it. First, the design approach was developed appropriating the whole or parts of traditional attire and applying decorative items in terms of a formal aspect. Secondly, the colors of the airline's homeland symbols or natural environment were used while, thirdly, the fabrics represent glocalism by employing folk elements of the region and patterns of nature for a uniform design. Induced from these design analyses, the aesthetic characteristics of airline uniforms reflecting glocalism are traditionality, naturality, and compromisability. To begin with, traditionality is what is realized in interpreting the historical aesthetics in a contemporary perspective, contributing in inspiring the historical value of the homeland and contributing to the establishment of identity by applying forms and colors of traditional garments with folk patterns on a uniform design. In addition, naturality means the reorganization of unprocessed pure nature, expressing the image of nature through colors taken from the natural environment or motifs of the regional plants. Finally, combining general sensibilities with diverse cultural features, compromisability is realized as a modern design which combines a standardized uniform with the aesthetic components of the local environment and traditional garments.

This paper considers some significances and limitations in application of Rawls' liberal theory of justice to conceptualization of environmental and ecological justice. It first reviews Rawls' liberal theory of justice, then examines how his theory of justice considers natural resources and can be applied to develop distributive theory of environmental justice, and finally explores what kinds of problems would be generated when Rawls' theory of justice is to be extended to animals and other natural components. In Rawls' theory of justice the status of natural resources is described as a objective condition for justice, but it is argued that natural resources should be seen as a substantial component of just production and distribution. It also can be stressed that his theory of justice does not secure a just result of resource distribution, even though it has a great significance for just procedure of distribution. Finally, it seems hardly possible to extend Rawls' theory of justice to animals and other natural components to develop a Rawlsian theory of ecological justice, because liberalism and Western tradition of science on the basis of which Rawls' theory of justice has developed presuppose an ontological dualism of human beings and other natural components, and hence cannot recognize the inherent value of nature.

This research aimed at investigating Kim Gyoshin's recognition on Korean traditional ideology and harmony of Christian idea and traditional idea through the writing and diary in "Bible Joseon". Kim Gyoshin expressed positive interest in Korean traditional idea and traditional religion, and intended to localize Christian belief through communicating with them. He expressed infinite respect for national cultural asset of Buddhism, intending to research Korean Buddhism. He paid utmost attention to Confucianism among traditional ideas. He had a strong affection for learning(好學), benevolence(仁義), conscience(良心) of Confucianism as patriotic character. He calmly practiced caution and solitary(愼獨) of sincere(誠), solemnity(敬) of Confucianism through his life, however he chose Christian belief by accepting atonement belief realizing human sinful nature fundamentally inherent in human being. He personally respected Confucius and lived after the model of him, however he searched the spirit of life to renew the people from Christianity. Academically, he respected Confucius, and believed in Jesus in religion. He highly evaluated the attitude of patriot(志士), which highly regarded the academic attitude of learning(好學) and benevolence(仁義), in this regard, criticized blind and non-intellectual belief. He had an open attitude toward Korean traditional idea with no prejudice. As human individuals have their own inherent moral value, he viewed that each people would have their inherent ethnicity and mission. He considered that Korean Peninsula where contradiction and yoke of the world history are inherent is the center of East Asia that would purify injustice of the world. He viewed that Korean people had owned their original good heart[仁] even before Buddhism and Confucianism had been transmitted to the country. He determined that Korean people were good people, who received goodness from the heaven. However, while Uchimura created Japanese style Christianity by adapting Japanese knighthood to Christian idea, Kim Gyoshin lacked sharp critical mind regarding how to establish Korean style Christianity by adapting which of Korean traditional idea to Christian idea.

This study attempted to investigate the plasticity of Korean paper expressed in contemporary fashion after general inquiry into Korean paper and examine the aesthetic beauty of fashion design using Korean paper. It used the literature review and empirical data analysis together. Korea-paper fashion design, the object of actual investigation, was for Korean-paper fashion from the 1990s to the present. As a result of analysis, the following findings were obtained: First, the natural, warm and soft texture seen as pureness in Korean paper enables us to elicit naturalness from liberalness. In addition, Korean paper not only has the tough characteristic of its material but also has the natural characteristic of abandoning its original nature and complying and adhering to its a given nature. Korean-paper fashion design, using this natural beauty and frank nature, bears the pure image of excluding decoration. Second, the overlapping of the surface on the surface expressed in Korean-paper fashion design forms one space with the sense of depth because of its transparency and expresses temporality through repetition. And the work of folding it with other materials and pasting them up with together demonstrates the effect of reflection because its original transparency. This effect is the specificity created in the collage technique using Korean paper and is the advantage of coming to obtain a wider freedom of expression. Korean-paper fashion design expresses transparency using this repetition and overlapping, Third, Korean paper has the simple rather than luxurious aspect. Owing to this nature, fashion design looks as if there were the greed inherent behind the work made from Korean paper though the complex technique applied to it. And it expresses the restraint of Korean paper using its original white color, the exclusion of decoration and simple design. Fourth, Korean paper is more likely to be changed by the outside influence because of formation. It has its peculiar aesthetic value and original artistry to an extent that it is regarded as one artistic work. The quality and texture of Korean paper diversely vary according to the artist's working process. Like this, Korean paper is easily fused into some object without exclusivity though it may be added to it. Korean-paper fashion design has the beauty of creation that is to create a new world because Korean paper is fused into another material due to its soft nature.

Due to increasing spectrum demand for new wireless devices applications, cooperative spectrum sensing (CSS) paradigm is the most promising solution to alleviate the spectrum shortage problem. However, in the interweave cognitive radio (CR) system, the inherent nature of CSS opens a hole to Byzantine attack, thereby resulting in a significant drop of the CSS security and efficiency. In view of this, a weighted differential sequential single symbol (WD3S) algorithm based on MATLAB platform is developed to accurately identify malicious users (MUs) and benefit useful sensing information from their malicious reports in this paper. In order to achieve this, a dynamic Byzantine attack model is proposed to describe malicious behaviors for MUs in an interweave CR system. On the basis of this, a method of data transmission consistency verification is formulated to evaluate the global decision's correctness and update the trust value (TrV) of secondary users (SUs), thereby accurately identifying MUs. Then, we innovatively reuse malicious sensing information from MUs by the weight allocation scheme. In addition, considering a high spectrum usage of primary network, a sequential and differential reporting way based on a single symbol is also proposed in the process of the sensing information submission. Finally, under various Byzantine attack types, we provide in-depth simulations to demonstrate the efficiency and security of the proposed WD3S.

This paper starts out with a review of the concepts of naturalism and natural clothes. Based on these concepts, the paper aims to create nature-friendly and high-value modem designs by grafting natural images from butterflies into human bodies. The images of butterflies are combined to show distinguished luxury and diversity with natural materials such as denim. As for the design technology, Adove Illustrator 10, Photoshop 7.0, and Prima Vision Textile Design System are used since they are very popular in the CAD system. The followings are the main findings of our research. Naturalism displays its objectivity based on its inherent interest in human nature and its factual description in scientific approaches with an intention to find a true meaning of human life in nature. Natural clothes can be defined as the clothes of natural silhouette which are made of pure materials in natural colors and dyes from natural motifs such as animals, plants or natural phenomena. We have realized that the visually distinguished looks of butterflies are indeed far more luxurious than those of any other insects and this visual distinction can be utilized to attract the attention from designers. Lastly, it turns out that the digital printing technique can create more variety in colors and design forms than the manual printing, thereby providing designers with more options and practicality.

This study used a Chatbot, a generative artificial intelligence (AI), to analyze the interaction between the Chatbot and students when exploring critical minerals from an epistemological aspect. The results, issues to be kept in mind in the teaching and learning process using AI were discussed in terms of the role of the teacher, the goals of education, and the characteristics of knowledge. For this study, we conducted a three-session science education program using a Chatbot for 19 high school students and analyzed the reports written by the students. As a result, in terms of form, the students' questions included search-type questions and non-search-type questions, and in terms of content, in addition to various questions asking about the characteristics of the target, there were also questions requiring a judgment by combining various data. In general, students had a questioning strategy that distinguished what they should aim for and what they should avoid. The Chatbot's answer had a certain form and consisted of three parts: an introduction, a body, and a conclusion. In particular, the conclusion included commentary or opinions with opinions on the content, and in this, value judgments and the nature of science were revealed. The interaction between the Chatbot and the student was clearly evident in the process in which the student organized questions in response to the Chatbot's answers. Depending on whether they were based on the answer, independent or derived questions appeared, and depending on the direction of comprehensiveness and specificity, superordinate, subordinate, or parallel questions appeared. Students also responded to the chatbot's answers with questions that included critical thinking skills. Based on these results, we discovered that there are inherent limitations between Chatbots and students, unlike general classes where teachers and students interact. In other words, there is 'limited interaction' and the teacher's role to complement this was discussed, and the goals of learning using AI and the characteristics of the knowledge they provide were also discussed.

Meat quality is a very difficult term to define because it means different things to different people. When purchasing beef, consumers in the United States are likely to consider color, price, marbling level, subcutaneous fat trim, or cut thickness when determining the quality of beef. Once consumers have consumed the product, meat quality becomes exponentially more difficult to define due to the subjective nature of this term. Traditionally, tenderness, juiciness, and flavor have been considered the three most important factors that determine the palatability of beef. Therefore, American meat science beef research and industry focus has turned to measuring and quantifying these 3 attributes objectively and subjectively, and to determining what influences them. In reviewing the scientific literature, attempting to meaningfully summarize the findings of the thousands of studies on beef meat quality is impossible due to the inherent differences in the objective and methodology of studies. Fortunately, the United States beef industry and their national trade association, the National Cattlemen's Beef Association (NCBA), have conducted numerous surveys and audits to characterize the quality of the products being produced and marketed by their cattlemen and the palatability perceptions of their consumers. The data produced by these studies is quite large and impossible to summarize in entirety in this review. Therefore, this review concentrates on the most important attributes that determine the value of a beef carcass and objectively measured and consumer-assessed palatability characteristics of fresh meat from these carcasses from 1987 through 2010.

The fashion industry analyzes the value of its essence with ecological design and is expressed as an innovative sculpture using digital technology. Accordingly, this study explores ecological images and digital technologies, categorizes types and derives their meanings through analysis of ecological images shown in modern digital fashion. A literature survey was conducted on ecological images and digital technology as a theoretical background. To analyze the expression type and internal meanings of ecological images, designs with ecological formability were selected and analyzed from related journals, books, and internet sites. The finding are as follows: The expression type was first identified as organic curved garment silhouettes of a non-material liquid with digital retouching. Second, ecological fashion design includes structural shape that applies the silhouette of an organism and patterning of the ecosystem. Third, ecosystems consist of interactions between components of an ecosystem that appear in the interactive type. Accordingly, the internal meanings of ecological images in modern digital fashion are: first, digital fashion can encircle the inherent concepts of nature as organic collections of individuals; second, digital ecological images emphasize a sense of community with coexistence and harmony, playing a complementary role; and finally, the images express perceptual features by providing people with transcendent experiences. This study is significant as it analyzes new formative features based on ecological systems in the digital fashion environment, establishes an aesthetic system through internal meanings, and enhances awareness of human-natural relationships.
