The field of sports has traditionally been a domain that practices and reinforces masculinity. However, in contemporary literature, observations and experiences of males in sports have expanded their ideas on masculinity as well as gender identity. Furthermore, there is an increase in males participating in non-orthodox masculine physical activities, most of which are known as "gender appropriate" for females such as cheerleading, dance, gymnastics, etc. Recently, pole dance – a stigmatized female-oriented activity – has become a newly introduced activity in the sports scene and one in which males are gradually engaging in worldwide. In the case of Korea, the phenomenon of men taking part in female-concentrated activities is not common; however, there are a rising number of male pole dancers visible through national competitions and media sources. Therefore, this study explores the experiences of Korean male exotic pole dance practitioners to understand how they define gender identity whilst participating in a highly female-oriented activity. It was found that research participants articulated beyond their biological sex and practice not to conform to social gender roles, and rather emphasized their manifested identity of individual self. Despite Korea's cultural and traditional aspects of gender norms, this study establishes a broader segment of gender ideas and expands the understanding of various identities spoken among male polers.

The primary purpose of this study is to explore the experiences of South Korean women "doing serious leisure" in what is widely known as a stigmatized activity, pole dance. It seeks to understand the experiences of South Korean women participating in pole dance and to investigate the strategies that are used to cope with the stigma that is experienced during participation. A qualitative research method was applied with an "insider" approach to collecting data. Data were collected through participation observations and in-depth interviews. The findings suggest that South Korean pole participants construct unstigmatized identities through their engagement in pole with its social stereotypes and stigma. Participants' identities have been firmly embedded as "pole dancers", "pole athletes", or "polers", which they do not feel the need to elucidate to those who are not active members. Their identities are surrounded and intertwined with their rationalized reason for participating in pole dance as serious leisure, along with their individual dedication which manifests their commitment by entering competitions and upgrading their pole skills. Participants and the pole dance community create a social atmosphere where their participation is not taken with stigma but rather with serious dedication to form their own interpretation of pole dance.

Recently, machine-learning algorithms and existing financial data-analysis methods have been actively studied. Although the term structure of government bonds has been well-researched, the majority of studies only analyze the characteristics of one country in detail using one method. In this paper, we analyze the term structure and determine the common factors using principal component analysis (PCA) and an autoencoder (AE). We collected data on the government bonds of three countries with major currencies (the US, the UK, and Japan), extracted features, and compared them. In the PCA-based analysis, we reduced the number of dimensions by converting the normalized data into a covariance matrix and checked the first five principal components visually using graphs. In the AE-based analysis, the model consisted of two encoder layers, one middle layer, and two decoder layers, and the number of nodes in the middle layer was adjusted from one to five. As a result, no significant similarity was found for each country in the dataset, and it was appropriate to extract three features in both methods. Each feature extracted by PCA and the AE had a completely different form, and this appears to be due to the differences in the feature extraction methods. In the case of PCA, the volatility of the datasets affected the features, but in the case of AE, the results seemed to be more affected by the size of the dataset. Based on the findings of this study, this topic can be expanded to compare the results of other machine-learning algorithms or countries.

Recently, there has been a significant increase in female audiences and fans at professional sport events in South Korea (hereafter Korea), particularly women's volleyball. This growth in higher viewer ratings and stadium attendance is attributed to elements such as athletes' sportsmanship and their dynamic athletic performances. However, there is little known about the Korean women's volleyball league's fanbase. Previous studies have focused on the experiences of male and female fans' interpretations of sport fan characteristics, experiences of female fans, or those of traditionally male-dominant sports such as ice hockey and football. Therefore, this study explores the experiences of self-identified women fans of women's professional volleyball in Korea. We seek to understand how research participants were introduced to volleyball, how they express their fanship, and how they define sport fans. According to the findings, a combination of structural systems in higher education and media streaming during pandemic restrictions has allowed volleyball content to become more accessible to research participants. Furthermore, the study examines how dukjil and fan service play significant roles in maintaining fanship, and the influence of generational characteristics on how women fans perceive and define sport fans.

We examined the influence of physical education activity on peer acceptance in adolescents over time, and how this influence changes based on gender and motivation climate in class. Participants were 157 middle school freshman students (81 boys, 76 girls) at a school in South Korea.
Results of hierarchical linear modeling showed that peer acceptance among girls decreased over the 12-week period of our study, but there were no significant changes in peer acceptance among boys. Furthermore, peer acceptance decreased when boys participated in physical education activity
more diligently, but this negative relationship weakened when the class was instructed in a noncontrolling climate. However, physical education activity and class climate did not significantly affect peer acceptance among girls. The results imply that the role of physical education teachers
is important in the formation of peer acceptance at the beginning of the school year.

We consider spin-polarized transport in a quantum spin Hall antidot system coupled to normal leads. Due to the helical nature of the conducting edge states, the screening potential at the dot region becomes spin dependent without external magnetic fields nor ferromagnetic contacts. Therefore, the electric current due to voltage or temperature differences becomes spin polarized, its degree of polarization being tuned with the dot level position or the base temperature. This spin-filter effect arises in the nonlinear transport regime only and has a purely interaction origin. Likewise, we find a spin polarization of the heat current, which is asymmetric with respect to the bias direction. Interestingly, our results show that a pure spin current can be generated by thermoelectric means: when a temperature gradient is applied, the created thermovoltage (Seebeck effect) induces a spin-polarized current for vanishingly small charge current. An analogous effect can be observed for the heat transport: a pure spin heat flows in response to a voltage shift even if the thermal current is zero. ; This research was supported by MINECO under Grant No. FIS2011-23526, the Kavli Institute for Theoretical Physics through NSF Grant No. PHY11-25915 and the National Research Foundation of Korea (NRF) grants funded by the Korea government (MSIP) (Grant No. 2011-0030046). ; Peer Reviewed

Nonlinear transport coefficients do not obey, in general, reciprocity relations. We here discuss the magnetic-field asymmetries that arise in thermoelectric and heat transport of mesoscopic systems. Based on a scattering theory of weakly nonlinear transport, we analyze the leading-order symmetry parameters in terms of the screening potential response to either voltage or temperature shifts. We apply our general results to a quantum Hall antidot system. Interestingly, we find that certain symmetry parameters show a dependence on the measurement configuration. © IOP Publishing and Deutsche Physikalische Gesellschaft. ; SYH and ML were supported by the National Research Foundation (NRF) grant funded by the Korea government (MSIP) (no. 2011-0030046).
