The time reversal mirror (TRM) method for underwater communications has been developed to improve transmission performance with low complexity. However, digital communication parameters for TRM have not been researched deeply. This paper demonstrates that the TRM scheme obtains spatial diversity gain similar to multiple antennas, and proposes design methodologies of symbol interval, frame duration and transmission protocol for time reversal mirror transmission. Simulation results show that spatial diversity gain is achieved and the effect of ISI decreases as the number of transducer increases.

Museum Architecture, passing through modem times, have been requested to make changes in order to respond to the necessities of current times as well, so that they come to develop various kinds of programs other than a mere exhibition. That is, museum began recognizing the diversity of activities available in the spaces and the openness to the public. And tried to keep up with the changes by linking the museum buildings with local community in urban architecture as a result. Conversion design is methodology aims at reforming old buildings into a museum or revitalizing buildings of historical significance into exhibition center, so that it made possible to utilize the texts of historical, cultural cities, which in turn contribute to the diversity of urban architecture and protection of buildings in environmental crisis. In the sense, the paper analyzes the life-long contribution and dedication of Carlo Scarpa, an Italian architect, in the conversion of museum architecture, and studies the style, techniques, and features witnessed from his architectural works, and finally offers an insight and a directing post to take advantage of diverse ways likely applicable in our urban architectures. Scarpa's features in his museum architecture are classified as follows: First, contrasting expression of reiteration and side by side to express the continuity of time Second, he conveyed implicated meanings through inserting contracted factors of the locality and traditionality. Third, his interest in formative works and handicraft had an influence on shaping conversion space Finally, expression of accidentally to change of a point of view.

This study aims to suggest a direction for interior space design for fashion flagship stores in the future where the brand identity can become correctly recognized by the consumers, and consumers can have various and differentiated experiences. As research method, theoretical concept review and case study on brand communication and VMD were used. Specifically, for review on brand communication, concept, strategies, and space types were explored, and, for review on VMD, concept, purpose, and expressive elements were researched. Also, the study looked at the relevance between and importance of strategy types of brand communication and VMD. Through these reviews, strategy types of brand communication and analysis criteria for VMD application were written based on the research and analysis of 8 cases in Korean and elsewhere. The results of this study is as follows: Based on marketing-oriented thinking with understanding of VMD, the plan must accurately understand the image and identity pursued by the brand, take into account the store layout, atmosphere, product concept, trend, and display, so that the store can communicate with the customers with cognitive consistency, diversity of senses, and differentiation from other companies. Currently, fashion flagship stores in Korea are concentrated on sales in expressing VMD, and, therefore, are difficult to deliver brand identity to consumers and they require diversity in expressive elements in doing so. Therefore, in the interior space design of fashion flagship stores in Korea, brand communication must enhance cognitive, behavioral, relationship, and culture marketing, and, requires confirming VMD expression in details by linking with brand communication and specific expressions based on it.

The purpose of this study is to analyze the design characteristics of external appearances of Hundertwasser's housing projects through both literature review and field study, and to understand how Hundertwasser's architecture philosophy was embodied in the design of external appearances so such projects. The subjects of the analysis are: Hundertwasser House; In the Meadow Bad Soden; The Forest Spiral Darmstadt; and The Green Citadel Magdeburg. The conclusion of the study is as follows. The fundamental architecture philosophy of Hunderwasser is the close linkage between mankind and nature. He has proven, through his four housing projects mentioned above, that it is possible to build houses without destroying and in harmony with nature. Hundertwasser had identified vitality, irregularity and diversity as being the source of beauty of nature. Using the human creativity, he had embodied such elements into his housing projects, thus suggesting an ideal housing environment whereby humanity is respected. Hundertwasser made use of organic curved line and spiral shapes that exist in nature when designing his housing projects. His creativity was articulated through vitality, diversity, and irregularity in colour schemes and a wide range of form. Indeed, he was an architect pursuing the underlying nature of both human and nature. The current living environment in Korea can be characterized as being standardized and desolate, which is a result of housing projects being focused too much on functionalism. Through its analysis of Hundertwasser's housing projects, one of the objectives of this study is to contribute to a new design paradigm being called for today, including for housing projects to be more ecological and environmental-friendly. By motivating architects and appealing to their clients, this study hopes to motivate those involved in various housing projects to think progressively. Such an attitude change could assist in transforming and thus enhancing the overall living environment in Korea.

It is important to design the high-speed communication system in the hostile channel. Due to the frequency diversity, FD-OFDM that can be used for the high-speed communication is more robust to the noise or interference than ordinary OFDM. However, even the FD-OFDM becomes degraded in th ε strong narrow band interference channel. In this paper, we propose an AFD-OFDM system and analyze the communication performances in order to find out the more robust communication system in the hostile channel. So, the AFD-OFDM system can cover the drawback of the FD-OFDM and improve the BER performance than FD-OFDM. From the simulation results, FD-OFDM shows better performance than the ordinary OFDM. Furthermore, AFD-OFDM shows more excellent performance than FD-OFDM in the strong narrow interference channel.

Recently to introduce new services of ultra-high speed wireless access and systems beyond the 3rd generation mobile communication, 5 GHz band has been highly interested. As a way of getting the required frequency, it is considered that microwave relay bands below 6 GHz, which shows a slow decrease in demand and less cost-effectiveness, should be moved to other bands above 6 GHz. In this paper, as a tool for analyzing microwave link design and its service quality, the outage prediction based upon Vigants & Barnett＇s model is reviewed. To show outage and availability calculation, simulations are performed for the operating 4 GHz radio sites, and some results and features regarding frequency movement to 6.7 as well as 8 GHz are also discussed in terms of diversity techniques, bit error rate, and availability As the results, it is confirmed that only the diversity techniques of space or space and frequency can satisfy the annual objective of availability irrespective of frequency movement.

Modular furniture's colors, materials, finishing materials and quantities are determined by users' tastes and it's diverse functions, shapes and sizes are determined by the spaces of users. That is, modules satisfy the diversity of consumers, meet differentiated individuals' tastes and enable communications with consumers rather than delivering one-way messages of designers. The contemporary spaces of the 21st century have been gradually shifting from uniform spaces attaching weight on individuals' individuality and tastes and along with it, the consumption of expensive custom-made furniture and foreign branded furniture is increasing to satisfy those small numbers of consumers who want to express diversified individuality. The modular furniture as a concept which is the most suitable to Mass Customization can be produced in large quantities while considering the diverse needs and tastes of individuals and it does not have absolute shapes or sizes. The concept of modular furniture shows similarities to the creation of fractals that forms shapes by self similarities, repeats and similar transformations which is in the same context as the characteristics of a modular design that presents diversity with scales, materials and jointing points. Fractals will be combined with the digital media of today to present great plasticity and influence designers more heavily. Pursuit of new modeling is a requisite for the creation of future spaces and it will require continuous creativity and the transformable modular furniture will contribute to the satisfaction of diverse consumers' needs. This study is to propose the modular furniture that considers the diversity of the public in the 21st century and their individuality and that will enable interactions between designers and consumers.

In this paper, we present the performance analysis and design of a multi-path searcher operating over Rayleigh fading channels when multiple transmit antennas are employed in the down-link of W-CDMA system. The simulation results for the receiver operating characteristics (ROC) for 1, 2, and 4 transmit antennas are presented to corroborate the theoretical analyses. We also propose a procedure to find the optimum parameters of double-dwell serial searcher according to the number of the multiple transmit antennas. Our analyses and simulations indicate that post-detection integration is not necessary when the number of transmit antennas is more than two. Finally, we found that increasing transmit diversity order does not necessarily improve the detection performance when the received pilot signal strength is relatively low. Therefore, this gives us a practical criterion on increasing transmit diversity order.

In the context of a globalized society where diversity, equity, and inclusion (DE&I) have emerged as pivotal values, the fashion industry is undergoing scrutiny for its practices related to body DE&I. This study examines the nature of the discourse surrounding body DE&I within the fashion industry, focusing on how such discussions are shaped, disseminated, and manifested in both the industry and broader society. Critical discourse analysis is applied by utilizing, content from the New York Times and leveraging Fairclough's analytical framework encompassing textual, discursive, and social practices. The findings indicate that the New York Times emphasizes diversity, with a significant focus on the shapes and sizes of women's bodies, developing a narrative centered around women's bodies through visible and representative domains. The analysis suggests conflicted discourse, with prevailing critiques against the fashion industry's standardization of beauty and superficial inclusivity efforts. Moreover, the industry's adaptation to social demands for body DE&I is observed as sporadic, often leveraging non-normative bodies as a marketing strategy rather than genuinely embracing diversity. This study highlights the importance of continuous, in-depth discourse and social practices regarding DE&I within the fashion industry, as well as the need for systemic changes and policies that genuinely reflect societal demands for inclusivity. The findings provide a foundation for future investigations into the multifaceted relationship between fashion discourse, DE&I, and social practices, advocating for a more inclusive and critically aware fashion industry.
