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.

Brain tumor segmentation problem has challenges in the tumor diversity of location, imbalance, and morphology. Attention mechanisms have recently been used widely to tackle medical segmentation problems efficiently by focusing on essential regions. In contrast, the fusion approaches enhance performance by merging mutual benefits from many models. In this study, we proposed a 3D dual fusion attention network to combine the advantages of fusion approaches and attention mechanisms by residual self-attention and local blocks. Compared to fusion approaches and related works, our proposed method has shown promising results on the BraTS 2018 dataset.

Purpose - Social commerce is a certain way of how people buy some products together with others through the internet sites with mutual interactions among customers with the benefits of SNS when buying some products. At present, China market has some problems due to its rapid growing. However, empirical research or academic approach to social commerce has not been made enough. So, it is important for Chinese social market to develop and enlarge the customers with stability under the reliability and satisfaction. Also it is important for them to have repurchase intention. Nowadays, it is necessary to find the factors on customer satisfaction and trust, whereas consumers' dissatisfaction and unreliability are increasing on social commerce recently. In addition, researches on social commerce have been actively pursued by a variety of domestic and foreign scholars. However, researches on social commerce and Chinese market are short of, and they have some limitations because of the rapid growth of the market even though it is the early stage. The current situation requires researches on consumers' repurchase intention for continuing growth in the future according to the growth of Chinese social commerce. Research design, data, and methodology - The literature and the empirical studies are combined in order to achieve the purpose of the study. Deriving social commerce features and consumer properties as factors affecting the repurchase intention through the literature, and these factors have modeled a series of assumptions about the impact on satisfaction and trust, and have established hypotheses to verify them. The survey which is conducted to test the hypothesis and questionnaires are derived based on the variables discussed in the previous study. Appropriate measures were developed and tested on 227 respondents in China with a cross-sectional questionnaire survey. The path relationships of the research model were analyzed by SPSS 23.0 and Amos 23.0. Results - Research results about social commerce characteristics and factors affecting the repurchase intention are presented to Chinese market companies that adopt business models and consumer characteristics. In addition, this study focuses on the characteristics of social commerce, from two-dimensional characteristics of the consumer satisfaction, trust and the impact on the repurchase. Therefore, social commerce features and consumer properties based on the results of this study may lead the strategic implications that may increase the repurchase intention. Conclusions - The classification reviewing the previous findings related to social commerce and social commerce features affects social commerce repurchase (price discount, interactivity) and consumer characteristics (impulsivity, innovation, collectivism). It affects repurchase on factors and analyzes empirically. The empirical results identify major characteristics (social commerce characteristics, attributes) that affect the repurchase intention, and give the practical implications as well as the business strategies that are able to enhance social commerce repurchase consumers. Social commerce is a certain way of how people buy some products together with others through the internet sites with mutual interactions among customers with the benefits of SNS when buying some products.

The purpose of this research is to confirm how the determinant factors for shopping mall selection (proximity, parking facility, benefits, mutual interaction effects, physical environment, surroundings) affect attractiveness (image and appraisal) of the traditional markets and revisit intention and suggest strategic methods for revitalization of the traditional markets. Results of this research are drawn from a survey of customers who visit any of the twenty-two traditional markets in the Seoul area at least twice a week. Moreover, the theory is verified through the structural equation model analysis using the SPSS win 18.0 and AMOS 18 version statistics package. From the determinant factors of visiting traditional markets, parking facility, physical environment, and the surroundings were significant in image attractiveness; benefits, mutual interaction effects, and physical environment showed significant effects on appraisal attractiveness. Additionally, image attractiveness was not significantly influential in retention proneness while appraisal attractiveness was a key factor in deciding whether or not to revisit. Therefore, improvement in image is important but appraisal aspects like product reliability that customers can personally assess, are more essential for revitalization of traditional markets.

Recently, Li and Hwang scheme proposed a biometrics-based remote user authentication scheme using smart card. It is asserted that this scheme has very excellent benefits by the operation cost efficiency based on the smart card, one-way function and biometrics using random numbers. But this scheme cannot provide the properly authentication, especially, it is analyzed as the vulnerable security scheme for Denial-of-Service(DoS) attacks by impersonate attacks. The attacker controls the insecure channel, they can easily fabricate messages to pass the user's or server's authentication, and the malicious attacker can impersonate the user to cheat the server and can impersonate the server to cheat the user without knowing any secret information. This paper proposes the strong improved scheme which can respond to multiple attacks by supplementing the function of integrity check from the server which applied variable authenticator and OSPA without exposing the user's password information. It is supplemented pregnable of disguise attack and mutual authentication of Li and Hwang scheme.

The aim of this study is to analyze the effect of the growing activities of large purchasing enterprises on the trust of small and medium size contractors, which is mediated by 'purchase accompany activity'. This subject study includes the first and second contractor companies in Korea. The results of this study are as follow. First, the knowledge and cost price sharing activities of major purchase vendor with cooperative company had a positive effect on the trust of cooperative company, however this was not so with the information sharing activities in that case. Second, the trust of contractors on large purchasing enterprises was positively influenced by sharing activities with purchasing activities of major company. Third, the knowledge and cost price sharing activities of purchasing enterprise with contractors on the sharing activities were mediated by the trust of contracting company on the large purchase enterprise. According to this study, the mediated effect of trust relationship can influence a contracting company. Whereas preceding studies of sharing activities were conducted about unidirectional instruct of large purchase enterprises to small and medium size contracting companies, this study was conducted on bidirectional effects, which included knowledge, cost price, information sharing activities between contracting companies and large purchasing enterprises. Conclusively, this study showed the possibility of spreading cognitive and change about mutual benefits strategy between small and medium size contracting company and large purchasing enterprise.

This paper proposes a secure and efficient anonymous authentication scheme for health information push service based on indoor location in hospital. The proposed scheme has the following benefits: (1)It is just based on a secure one-way hash function for avoiding complex computations for both health care operations users and health care centers. (2)It does not require sensitive verification table which may cause health care centers to become an attractive target for numerous attacks(e.g., insertion attacks and stolen-verifier attacks), (3)It provides higher security level (e.g., secure mutual authentication and key establishment, confidential communication, user's privacy, simple key management, and session key independence). As result, the proposed scheme is very suitable for various location-based medical information service environments using lightweight-device(e.g., smartphone) because of very low computation overload on the part of both health care operations users and health care centers.

Conditional Access System (CAS) is a core security mechanism of IPTV SCP (Service and Content Protection) which enables only authenticated user to be able to watch the broadcasting contents. In the past, it was general that CAS was built in Set-Top Box (STB) as hardware or as a detachable cable card. However, numerous researches in Downloadable CAS (DCAS), where users can download CAS code in their STB through their network, have been recently conducted widely due to the lack of security and scalability problem. In this paper, the security requirements of OpenCable based DCAS which is typical example of downloadable IPTV SCP will be derived, the novel authentication and key management scheme will be proposed by using the Authentication Proxy (AP) which is the core DCAS. Also, the benefits of the proposed system will be evaluated by comparison and analysis with preceding research.

The study derives various anticipated benefits resulting from locating small and medium sized IT service firms in a specific industrial cluster area. The study also derives IT service agility factors to obtain competitive advantages vital to real-time global enterprises. The anticipated benefits were then used to analyze how they improve the firms' agility. Using questionnaire data, factor analyses were used to figure out eight anticipated benefit factors including coordination, information sharing, business costs, speciality, communication, trust improvement, mutual business understanding, and reciprocity. The eight empirically derived benefit factors were then used to examine how they affect the IT service agility including flexibility, speed, responsiveness, and lean efficiency. The results of regression analyses showed that each one of the anticipated benefit factors except communication influence one or more IT service agility factors.
