Purpose: The purpose of this research was to examine the effect of the sensoryscape (sport fans' stadium experiences via the five senses) on connectedness and elation that sport fans have about their teams. Research design, data, and methodology: To achieve this purpose, structural equation modeling was conducted with a total of 417 KBO baseball fans. Results: The results of the research are as follows. First, stadium experiences via sport fans' sight, sound, and touch had positive effects on connectedness that consists of passion, nostalgia, supportive, and connected. Second, stadium experiences via sport fans' sight, sound, and taste had positive effects on elation that consists of happy, excited, pleased, proud, optimistic, and entertained. Conclusions: This research provides the first empirical evidence of the effects of sport fans' sensory experiences on emotions associated with sport teams. In order to maximize connectedness and elation that sport fans have about their teams, sport marketers need to develop specific sensory strategies that affect stadium experiences. Further implications were discussed.

This paper shows how the environmental parameters(temperature, humidity) in the greenhouse are influenced by air movement produced by air circulation fans. When the fans were used, they could make indoor temperature and humidity homogenious, but there was no significant difference in the location and number of fans. When the fans were not used during the night time, there was no significant difference in the temperature and humidity, but the standard deviation was reduced by using the fans.

There are practicality, ornamentality and symbolic in a folding fan among Western accessories, and that is a little tool to enhance the overall harmony of a dress. The purpose of this study was to examine Western folding fans in an effort to shed light on the history, culture, fashion and life of different ages in which folding fans had been used. It's specifically meant to look into the mentality of people who had used folding fans. The meaning and function of folding fans were investigated, and their diverse types and characteristics were analyzed. As a result, it's found that in the West, a folding fan was one of major accessories that had an inseparable relation to popular clothes in each age and were necessary for a perfect coordination. Folding fans had been used as ornaments for Western noble women since the 16th century. After a certain period of time passed by, the 18th century became the heyday of folding fans. At that time, folding fans were one of aesthetic art works that even served as a means of mental exchange.

In order to improve thermal comfort in the Rotunda, which is high and wide visiting space of the new national museum of Korea, eight ventilating fans were installed near the ceiling of Rotunda. It has been analyzed thermal comfort of Rotunda with/without ventilating fans by numerical simulation. To evaluate thermal comfort of the Rotunda, well-known indices, PMV and PPD were introduced. The results of present investigation show that temperature distribution of the case with fans is closer to target temperature than the case with-out fans at the breathing zone. In the case without fans, thermal stratification with 16$^{\circ}C$ of temperature difference occurs along the height of the Rotunda which makes the thermal environment worse and the PPD values reach up to 50% in the 6th floor connection passage. In the case with fans, however, the vertical temperature difference were reduced to 9$^{\circ}C$ and the PPD values were lower below 20%. Consequently, the ventilating fans adopted on this study are effectively used for improving the thermal comfort in large space structure with thermal stratification.

Despite the enormous success in Japan of Korean popular culture, including TV dramas and K-pop, over the past few decades, anti-Korean sentiment in the country has become increasingly visible and intense. In this article, we examine how young Japanese female fans of Korean popular culture engage with the Korean Wave discourse while also engaging with―or, rather, disengaging from―anti-Korean movements and hate speech. Whereas previous scholarship on the Korean Wave has emphasized the power of active fans' agency, this paper investigates how the fans who passionately and self-reflexively consume Korean popular culture understand and react to the growing anti-Korean sentiment in Japan. Through in-depth interviews with 15 of these fans in their 20s and 30s, we show how they have navigated the discursive space between appreciation for Korean culture and anti-Koreanism in Japan.

This research outlines the motivations behind the fan-lead marketing and promotional endeavours undertaken by musical group BTS's fan community, also known as ARMY. In highlighting the reciprocity in intimacy between the group and their fans, I argue that ARMY's desire to elevate BTS is embedded within structures of affect, despite the financial nature of the benefits the group and their company may reap. These fan-lead initiatives represent efforts towards a common goal, where success, whether it comes in the form of money or not, is a gift of gratitude and a show of mutual understanding from fans to BTS. Based on data from 22 interviews with fans, this research explores the motivations behind fan-lead marketing by looking at the affective properties of music consumption, the parasocial relationship, fan community dynamics, and the purchase of intimacy. Within these contexts, the promotion surrounding BTS's music, as organized by the fans, mimics profit-oriented behaviours but is ultimately a gesture towards the exchange of intimacy between fans and artist.

The fans installed in standard Hanwoo loose barns (room size : 10 m (width) $\times$ 5 m (length)) are frequently used to reduce Hanwoo's heat stress during hot weather and to dry the wet floor. However, the most effective method of installing fans has not been suggested yet. Therefore, this study was carried out to evaluate two methods of installing fans under the ceiling of Hanwoo loose barn by using CFD (Computational Fluid Dynamics) code, FLUENT and to recommend the optimum fan installing method. The fan installation options were fan tilting angles of $45^{\circ}$ and $0^{\circ}$ (horizontal). The fans of 1 m diameter were installed at 3 m above floor. A velocity scale on 10 cm and 110 cm above floor and air flow pattern were used as the parameters to evaluate the fan installing methods. The fans tilted at $45^{\circ}$ angle produced higher wind at 10 cm and 110 cm above floor and more uniform air flow pattern, compared with the fans installed horizontally. Based on these results, fans tilted at $45^{\circ}$ angle may help to reduce Hanwoo's heat stress and will dry the floor better than fans installed horizontally. Therefore, it is suggested that the fans of 1 m diameter in a standard Hanwoo loose barn should be installed at a $45^{\circ}$ tilt angle and 3 m above floor with spacing of 5 m at the center of a room column.
