Accurate design models for predicting the shear resistance of headed studs in solid concrete slabs are essential for obtaining economical and safe steel-concrete composite structures. In this study, symbolic regression with genetic programming (GPSR) was applied to experimental data to formulate new descriptive equations for predicting the shear resistance of studs in solid slabs using both normal and lightweight concrete. The obtained GPSR-based nominal resistance equations demonstrated good agreement with the test results. The equations indicate that the stud shear resistance is insensitive to the secant modulus of elasticity of concrete, which has been included in many international standards following the pioneering work of Ollgaard et al. In contrast, it increases when the stud height-to-diameter ratio increases, which is not reflected by the design models in the current international standards. The nominal resistance equations were subsequently refined for use in design from reliability analyses to ensure that the target reliability index required by the Eurocodes was achieved. Resistance factors for the developed equations were also determined following US design practice. The stud shear resistance predicted by the proposed models was compared with the predictions from 13 existing models. The accuracy of the developed models exceeds the accuracy of the existing equations. The proposed models produce predictions that can be used with confidence in design, while providing significantly higher stud resistances for certain combinations of variables than those computed with the existing equations given by many standards.

This study aimed to present pioneering data on the use of Metaverse through a case study on the use of Metaverse by luxury brands and to reveal the intrinsic value of Metaverse in the fashion industry. The study was conducted based on literature data such as various articles and papers related to Metaverse and cases of luxury brands. For luxury brands data, we used Interbrand and LYST. As a result, Gucci, Louis Vuitton, Balenciaga, and Burberry were selected. Examples of the use of luxury brands' Metaverse use include; Gucci actively embraced digital technology and used Metaverse technology for the most diverse purposes such as promoting new products, opening seasons, and experiences. Louis Vuitton and Balenciaga focused on the entertainment and games. Burberry focused on promoting and experimenting with new products. As a result of the study, the intrinsic value of the Metaverse is as follows. First, there are no restrictions on time, scale, and institution. Second, active information acceptance is possible; Information can be selectively accommodated through participation and communication using Metaverse. Third, customers and businesses interact in equal positions. As customers participate and communicate, their ties with companies deepen, thus the can create a brand image together. Through Metaverse fashion, customers experiences are not limited to reality and the can directly access optional information. Based on the above examples and values, we hope those fashion companies and Metaverse media will innovate desings to match the trends and the seasons.

This paper reports a case study of SevenBräu, the first company to acquire a license for small and medium scale beer manufacturing in Korea. This study explores how SevenBräu analyzed its consumers, competition, and environment to set its target market and successfully positioned itself to explore new markets in Korea. The company accomplished this through a mixture of marketing strategies with differentiated products and consumer benefits. SevenBräu has been growing fast and establishing its image as a "high-quality craft beer locally produced in a traditional way" and a "beer with regional characteristics," with young consumers (aged 20 to 35) as the main target. Such remarkable growth of SevenBräu can be attributed to factors such as: (1) product differentiation to satisfy the needs of consumers for taste, flavor, diversity, and freshness, (2) developing brands with regional characteristics and actively communicating its strategy through earned and owned media, and (3) sustainable management, considering both social value creation and environmental performance. Lastly, this case study presents challenges in the areas of brand management, value delivery network, and communication that SevenBräu needs to address in the beer market that faces increasing competition.

Purpose: The study's objective was to examine the impact of brand personality dimensions on consumer behavior for laptop purchases in Nepal. Research Materials and Methods: The study included descriptive and explanatory research designs. A structured questionnaire with a purposive sampling method was employed to gather the necessary information for the study. The survey data were analyzed using a quantitative approach. The study used descriptive statistics to characterize the response conditions. Correlation analysis was used to investigate the relationship between brand personality dimensions and consumer behavior. Regression path analysis was employed to identify the effect of brand personality dimensions and consumer behavior. Results: The result of regression path analysis showed that the three dimensions - competency, ruggedness, and sophistication, have a significant effect on consumer behavior, and the two dimensions- sincerity and excitement do not have a substantial impact on consumer behavior in laptop buying in Nepal. Conclusions and Implications: Such findings can serve as pioneering empirical evidence and provide a framework for marketers and future studies in various scenarios. The study's findings can help marketing managers in handling information management. Manufacturers, wholesalers, and retailers can also use the results in formulating marketing strategies, and marketers need to be aware of such considerations for influencing consumer behavior.

In March 1245, Pope Innocent IV authorized three missions to the Mongols, seeking information about this menace from the East and summoning Eastern Christian support against an anticipated Mongol onslaught. Only one of the missions, led by John of Plano Carpini, reached Mongolia-the first-known Western European party to reach East Asia by a land route. Traveling along the Silk Road's new "Grasslands Route," John and his companion Benedict reached the camp of Güyüg Khan, where they witnessed his installation as the Great Khan. Upon their return to the papal court in 1247, they delivered Güyüg's letter demanding the submission of the pope and all the West's princes. John also presented a detailed report on what he and Benedict had learned. A close reading of it reveals a master intelligence operative at work. In addition to presenting an overview of Mongol history and culture, Friar John's report provides detailed information on the Mongols' grand strategy, their military organization and armaments, and their battle tactics. Turning from intelligence gathering to military operations, he offered practical advice on how to meet and defeat the coming Mongol onslaught, an attack that, providentially for the West, never came. What did occur was a modest but significant migration of Western missionaries and merchants to East Asia in the century following this pioneering journey.

The paper addresses Erik Cohen's pioneering work on tourism in Thailand, specifically his publications on the relations between Thai women and foreign (farang) men in tourist-oriented encounters. Of sociological-anthropological interest is his conceptualization of these relations as "open-ended prostitution as a skilful game of luck" based on his study of a Bangkok soi (lane) in 1981-1984, and his exploration of Thai culture in terms of ambiguity and contradiction. On the basis of recent ethnographic research in the northern Thai tourist hub of Chiang Mai and wide-ranging observations on tourism development in Thailand, we examine continuity and change in these male-female engagements since Cohen's research, especially in the context of the increasing availability of such electronic agencies as social media, messaging, video chat, and internet dating. Whereas Cohen's concept of ambiguity and illusion has tended to disappear from physical spaces, it seems to have resurfaced in virtual space. The complexities of host-guest relations, and particularly the interactions both within the variegated category of "guests" themselves and then between their "hostesses" are explored in terms of sites of tourism-oriented encounters in both physical and virtual space so as to deconstruct these oppositional categories which have been formative in studies of tourism.

Different molecular lines trace different physical environments (with various densities and temperatures) within molecular clouds (MCs). Therefore, multimolecular line observations are crucial to study the physical and chemical structures of MCs. We observed the Orion A and Ophiuchus clouds in six different molecular lines as a Taeduk Radio Astronomy Observatory Key Science Program (TRAO-KSP), "mapping Turbulent properties In star-forming MolEcular clouds down to the Sonic scale" (TIMES; PI: Jeong-Eun Lee). Here, we investigate the characteristic relations between the observed lines by performing the Principal Component Analysis (PCA). We also investigate the correlation between the line intensity distributions and the physical parameters, such as the gas column density and dust temperature. Finally, we will discuss how the correlations among different chemical tracers vary with the star formation environments.
