The professional alliance between disciplines of architecture and furniture design in the interwar years as displayed in the prominent architectural exhibitions of the era is interesting in the context of professionalization of American architecture. The way furniture design gradually became part of the architectural shows not only reflected but provided the practical field in which the architectural institution sought, under the new social order since the mid 1910s, a new professional cast-departing from the former milieu in the realm of high-art by the Beaux-Arts Movement. Exhibitions held by the Architectural League of New York in the 1920s revealed that the early impetus for reformation toward efficiency had been subsumed by the system of Beaux-Arts. By contrast, "The Architect and the Industrial Arts" show of the Metropolitan Museum of Art, in which the most prominent architects of the era exercised their professional expertise in the design of "Moderne Style" interior furnishings, clearly shows how architects, in the milieu of expanding commercial market, sought to align their profession as industrial designers.

K/DA is a K-pop virtual idol based on the game character. This study analyzed the creation process, characteristics and existential meaning of virtual idols from the perspective of Pataphysics. K/DA is a character with both characteristics of game character and K-pop girl group. Also, virtual character and real idol share the body through motion capture and augmented reality(AR). As a result, K/DA crosses virtual and reality, and at the same time becomes a pataphysical subject that does not belong to either virtual or reality. K/DA is suggested a third zone where digital subjects will be located in the future.

Korea's famous soccer players are steadily performing well in international leagues, which led to higher interests of Korean fans in the international leagues. Reflecting the growing social phenomenon of rising interests on international leagues by Korean fans, the study examined the overall consumer perception in the consumption of uniform by domestic soccer fans and compared the changes in perception following the transfers of the players. Among others, the paper examined the consumer perception and purchase factors of soccer fans shown in social media, focusing on periods before and after the recruitment of Heung-Min Son to English Premier League's Tottenham Football Club. To this end, the EPL uniform is the collection keyword the paper utilized and collected consumer postings from domestic website and social media via Python 3.7, and analyzed them using Ucinet 6, NodeXL 1.0.1, and SPSS 25.0 programs. The results of this study can be summarized as follows. First, the uniform of the club that consistently topped the league, has been gaining attention as a popular uniform, and the players' performance, and the players' position have been identified as key factors in the purchase and search of professional football uniforms. In the case of the club, the actual ranking and whether the league won are shown to be important factors in the purchase and search of professional soccer uniforms. The club's emblem and the sponsor logo that will be attached to the uniform are also factors of interest to consumers. In addition, in the decision making process of purchase of a uniform by professional soccer fan, uniform's form, marking, authenticity, and sponsors are found to be more important than price, design, size, and logo. The official online store has emerged as a major purchasing channel, followed by gifts for friends or requests from acquaintances when someone travels to the United Kingdom. Second, a classification of key control categories through the convergence of iteration correlation analysis and Clauset-Newman-Moore clustering algorithm shows differences in the classification of individual groups, but groups that include the EPL's club and player keywords are identified as the key topics in relation to professional football uniforms. Third, between 2002 and 2006, the central theme for professional football uniforms was World Cup and English Premier League, but from 2012 to 2015, the focus has shifted to more interest of domestic and international players in the English Premier League. The subject has changed to the uniform itself from this time on. In this context, the paper can confirm that the major issues regarding the uniforms of professional soccer players have changed since Ji-Sung Park's transfer to Manchester United, and Sung-Yong Ki, Chung-Yong Lee, and Heung-Min Son's good performances in these leagues. The paper also identified that the uniforms of the clubs to which the players have transferred to are of interest. Fourth, both male and female consumers are showing increasing interest in Son's league, the English Premier League, which Tottenham FC belongs to. In particular, the increasing interest in Son has shown a tendency to increase interest in football uniforms for female consumers. This study presents a variety of researches on sports consumption and has value as a consumer study by identifying unique consumption patterns. It is meaningful in that the accuracy of the interpretation has been enhanced by using a cluster analysis via convergence of iteration correlation analysis and Clauset-Newman-Moore clustering algorithm to identify the main topics. Based on the results of this study, the clubs will be able to maximize its profits and maintain good relationships with fans by identifying key drivers of consumer awareness and purchasing for professional soccer fans and establishing an effective marketing strategy.

The purpose of this study is to provide the basic information necessary to develop sports uniform design by comparing and analyzing the color features and images of professional football uniforms in Korea and foreign countries. The subjects of this study were limited to 5 top leagues in Europe (Premier League, Primera Liga, Bundesliga, Serie A, and Ligue 1) as well as J-League, and K-League. This study was done using the 2012/2013 season home and away uniforms for European leagues and 2013 season home and away uniforms for Korean and Japan leagues. Using the Adobe photoshop CS2 eyedropper tool, color chips and RGB values were extracted from digital images and converted into HV/C of Munsell Conversion. Finally, a total of 735 colors were used for the analysis. The color image scale by Shigenobu Kobayashi was used to position the color images. The results are as follows. First, the color analysis of professional football uniforms in leagues suggested that chromatic color (53.7%) was more prevalent than achromatic color (46.3%). The two most common colors of the ten chromatic colors were R(19.7%) and PB(18.0%), followed by Y(5.4%), RP(2.0%), G(1.9), GY(1.8%), B(1.6%), YR(1.5%), P(1.1%), and BG(0.7%). Second, for the color tone comparison and analysis of professional football uniforms in leagues, the most commonly used color tone was W(28.4%), followed by v(25.5%), Bk(16.3%), s(5.8%), dk(5.2%), b/lt(5.2%), dp(3.0%), sf(2.0%), ltGy(1.0%), p(0.5%), G/dkGy(0.4%), and ltg/mGy (0.1%). Third, for the comparison and analysis of color and color tone of professional football uniforms in leagues, W(28.4%), R(v)(17.7%), and Bk(16.3%) were commonly used. Finally, for the comparison and analysis of color images of professional football uniforms in leagues, the most commonly used color image was a casual image(31.8%), followed by modern image(26.5%), dynamic12.8%), cool casual(12.0%), gorgeous(9.3%), clear(6.6%), chic(3.5%), and elegant images.

Major League Baseball (MLB) records and releases the trajectory data for every baseball pitch, called the PITCHf/x, using three high-speed cameras installed in every stadium. In a previous study, the quality of the pitch was assessed as the expected number of bases yielded using PITCHf/x data. However, the number of bases yielded does not always lead to baseball scores, or runs. In this paper, we assess the quality of a pitch by combining baseball analytics metric Run Expectancy and Run Value using a Random Forests model. We compare the quality of pitches evaluated with Run Value to the quality of pitches evaluated with the expected number of bases yielded.

The purpose of this study was to estimate the determinants of victory and defeat through analyzing records of Korean men pro-basketball. Statistical models of victory and defeat were established by collecting present basketball records (2010-2011, 2011-2012 season). Korea Basketball League (KBL) informs records of every pro-basketball game data. The six offence variables (2P%, 3P%, FT%, OR, AS, TO), and the four defense variables (DR, ST, GD, BS) were used in this study. PASW program was used for logistic regression and Answer Tree program was used for the decision tree. All significance levels were set at .05. Major results were as follows. In the logistic regression, 2P%, 3P%, and TO were three offense variables significantly affecting victory and defeat, and DR, ST, and BS were three significant defense variables. Offensive variables 2P%, 3P%, TO, and AS are used in constructing the decision tree. The highest percentage of victory was 80.85% when 2P% was in 51%-58%, 3P% was more than 31 percent, and TO was less than 11 times. In the decision tree of the defence variables, the highest percentage of victory was 94.12% when DR was more than 24, ST was more than six, and BS was more than two times.

This research is dedicated to slope stability analysis using novel intelligent models. By coupling a neural network with spotted hyena optimizer (SHO), salp swarm algorithm (SSA), shuffled frog leaping algorithm (SFLA), and league champion optimization algorithm (LCA) metaheuristic algorithms, four predictive ensembles are built for predicting the factor of safety (FOS) of a single-layer cohesive soil slope. The data used to develop the ensembles are provided from a vast finite element analysis. After creating the proposed models, it was observed that the best population size for the SHO, SSA, SFLA, and LCA is 300, 400, 400, and 200, respectively. Evaluation of the results showed that the combination of metaheuristic and neural approaches offers capable tools for estimating the FOS. However, the SSA (error = 0.3532 and correlation = 0.9937), emerged as the most reliable optimizer, followed by LCA (error = 0.5430 and correlation = 0.9843), SFLA (error = 0.8176 and correlation = 0.9645), and SHO (error = 2.0887 and correlation = 0.8614). Due to the high accuracy of the SSA in properly adjusting the computational parameters of the neural network, the corresponding FOS predictive formula is presented to be used as a fast yet accurate substitution for traditional methods.
