This study's purpose is to revive pre-construction situation earlier than construction of media facade using light-emitting diode, and analyze the strong and weak points of simulation image making process and technology, including lots of expressing methods. Exterior building decoration that was originated from Super Graphic led to the LED construction with a trend of increased night activities of these days. Initial Super Graphic was just in the level of deciding what to do with simple CAD drawings, but today's media facade construction is not so simple as the previous ones. This is because of the problems that should think about balances between neighboring environment and buildings, including high construction costs. According to survey results, media facade construction simulation's various expressing methods, its processes of analysis, and its strong & weak points will suggest standards for its size of construction and simulation purpose, including recommending suggestions that can respond rapidly by clients' diverse demands.

The practice of identifying the potential zones for mineral exploration in a speedy and low-cost method includes the use of satellite imagery analysis as a part of remote sensing techniques. It is challenging to explore the iron mineralization of a region through conventional methods which are a time-consuming process. The current study utilizes the Hyperion satellite imagery for mapping the iron mineralization and associated geological features in the Irikkur region, Kannur, Kerala. Along with the remote sensing results, the field study and laboratory-based analysis were conducted to retrieve the ground truth point and geochemical proportion to verify the iron ore mineralization. The MC simulation showed for shielding properties indicate an increase in the linear attenuation coefficient with raising the Fe₂O₃+SiO₂ concentrations in the investigated rocks where it is varied at 0.662 MeV in the range 0.190 cm^-1 - 0.222 cm^-1 with rising the Fe₂O₃+SiO₂ content from 57.86 wt% to 71.15 wt%. The analysis also revealed that when the γ-ray energy increased from 0.221 MeV to 2.506 MeV, sample 1 had the largest linear attenuation coefficient, ranging from 9.33 cm1 to 0.12 cm^-1. Charnockite rocks were found to have exceptional shielding qualities, making them an excellent natural choice for radiation shielding applications.

Rather the ballot paper design could influence voting behavior, there is less study upon the designing ballot paper and the importance of information design. This study examines the possibility of error occurring in the ballot paper design under the rules of Public Official Election Act. To do this, we conducted a heuristic evaluation method to review regulations, and an empirical experiment with closed groups. From this, we found that (1) diverse cases of ballot paper can be produced, and (2) various fonts, sizes, and materials can be used. Accordingly, it is inevitable to deliver regulations on (1) the usage of chromaticity and image, (2) the applying universal designed-typography, and (3) the margin for the spacing between ballot boxes. This study, at the end, suggests institutional measures for securing the validity and legitimacy on the decision-making process to remove latent ambiguity in ballot paper designing.

The digital environment, which has been rapidly developing since the beginning of the 21^st century, has become more specific due to COVID-19, and marketing strategies are rapidly changing to suit purchasing activities of Generation MZ, whose online purchases are becoming the center of their lives. A public relations agency is generally responsible for all aspects of making a client's product or service visible to the public through various forms of media. Among them, a company that performs only fashion-related tasks is called a "fashion PR agency". Now, the fashion industry is also centered on the e-commerce environment, and various digital marketing strategies have been developed and directly related to sales. This study examined the current status of online media and digital marketing, analyzes the aspects of fashion brand promotion strategies and methods in the e-commerce era, focusing on the work of fashion PR agencies, and suggests the direction of new online and offline promotion methods based on marketing and technological aspects. As a result of the study, first, theories on strategies for online media and digital marketing were examined, and found that the amount of online promotion has recently increased and become more specialized. Second, this study examines the concept of fashion PR agencies and analyzed their main tasks through interviews with fashion PR professionals. Third, based on successful online fashion promotion cases, the study analyzed fashion promotion strategies and methods that are being integrated online and offline in the e-commerce era. The main methods included SNS strategy, content strategy, performance strategy, influencer strategy, and event strategy, and it is suggested that integrated management is necessary for consistent brand image management, and an IMC (Integrated Marketing Communication) strategy, which intensively manages all strategies, should be employed.

The purpose is to derive its aesthetic characteristics by objectifying the visual image of the YouTube campaign into adjectives. As a result, we intend to identify advertising strategies that use them as basic data for setting fashion design concepts. A group of experts in fashion majors watched each of them, wrote adjectives, and collected 75 adjectives. By analyzing the frequency of adjectives, aesthetic characteristics were derived with adjectives recording the upper number of times, and the results were obtained that they had the characteristics of deconstruction. The conclusions of this study are as follows. First, Tamburin's Jenny appeared to be strange, scary, rambling and charming. Among the internal meanings of deconstruction due to spatial, social, and psychological distance from consumers, it can be said that T.P.O's mutual textuality and play of interaction. Second, Gucci Cruise be chosen rural, strange, wild, unharmonious, and difficult, which is a mixture of intertextuality and play of T.P.O. Third, The Excise Gucci Campaign parodies that juxtaposes six films directed by Stanley Kubrick, making them strange, retro, difficult, interesting, and wrong. Deconstructionist de-genre and de-boundary Fourth, Kenzo World is weird, dynamic, wrong, difficult, difficult, and confused, which correspond to T.P.O's interactive textuality, play of the second half, and destruction and decomposition among the external expressions of deconstruction. Fifth, Burberry Hero emphasized the aesthetic value of traditional men, so it was ostensibly wild, free, powerful, sensual, and fantastic. Compared to the lifestyle of men who usually work at work, this corresponds to play of second best.

This paper proposes a patent discovery method and strategy for Generative AI-related patents by utilizing qualitative evaluation indicators established based on the core components of the technology. Currently, the evaluation of patent quality relies on quantitative indicators, but existing quantitative indicators cannot represent the characteristics of Generative AI technology, making it difficult to accurately evaluate. Therefore, there is a need for additional qualitative indicators that consider technical characteristics based on patent claims, which can reveal the actual strength of the patent. In this paper, we propose a new evaluation index considering the technical characteristics of Generative AI. Core patents were selected using the proposed evaluation index, and the appropriateness of the proposed index was verified through the existing quantitative evaluation method for the selected core patents.

This study finds that the South Korean government's public diplomacy efforts have focused on promotional activities such as the "K-wave" or responses to controversial historical issues. However, the South Korean government needs to be more prepared for strategic responses to unexpected crises and subsequent communications. This paper attempts to apply crisis communication research developed in the field of public relations to public diplomacy. To do so, this research reviewed theories in crisis communication, an essential area of public relations, and developed a crisis communication model. The model was then applied to several crisis case studies to suggest how to develop response strategies and conduct communications. As a result, this research developed an Ongoing Public Diplomacy Crisis Communication Model (PDCCM) that can be applied to public diplomacy research and practice. The model identifies four crisis communication principles (be quick, be open, be consistent, be authentic) that should be applied in six phases. Following continuous social listening and monitoring, governments should analyze crisis situations using sense-making, develop short- and long-term crisis response objectives, response strategies, and communication messages depending on the level of responsibility, implement crisis communication, and conduct post-crisis evaluation.

Copper Filter Dryer (CFD) are responsible for removing impurities from the circulation of refrigerant in refrigeration and cooling systems to maintain clean refrigerant, and defects in CFD can lead to product defects such as leakage and reduced lifespan in refrigeration and cooling systems, making quality assurance essential. In the quality inspection stage, human inspection and defect judgment methods are traditionally used, but these methods are subjective and inaccurate. In this paper, YOLOv7 object detection algorithm was used to detect defects occurring during the CFD Shaft pipe and welding process to replace the existing quality inspection, and the detection performance of F1-Score 0.954 and 0.895 was confirmed. In addition, the cause of defects occurring during the welding process was analyzed by analyzing the sensor data corresponding to the Timestamp of the defect image. This paper proposes a method for manufacturing quality assurance and improvement by detecting defects that occur during CFD process and analyzing their causes.
