IDENTITIES ARISING FROM GAUSS SUMS FOR SYMPLECTIC AND ORTHOGONAL GROUPS
채희준,김대산 대한수학회 2010 대한수학회지 Vol.47 No.2
We express Gauss sums for symplectic and orthogonal groups over finite fields as averages of exponential sums over certain maximal tori. Together with our previous results, we obtain some interesting identities involving various classical Gauss and Kloosterman sums.

Background Building on the colloquial misunderstanding of South Korean album cover designs from 1994 to 2002 as mimicking American and Japanese visual styles, this paper examines the social, historical, economic, and technological contexts of that period. By expanding the design context to include political, economic, and technological dimensions, this research considers these factors as influential forces in the design process. The forces of globalization created a cycle of influence and export that shaped the design of this period. Methods To identify the problem of album cover design and image productions from the period of 1994 to 2002 as imitations, historical research was conducted alongside a thorough examination of the development of the K-pop music industry during this period. The research was then organized into three distinct impact factors that influenced K-pop album cover design and image production: 1) sociopolitical and economic factors, 2) influence on and of the K-pop music industry, and 3) technological change and the impact of the digital marketplace. A cultural research approach was taken in order to connect broader factors to the process of designing album covers and creating images for the K-pop industry. Results The results of this study create a holistic picture of the forces at work in the development of the K-pop music industry during the time period of 1994 to 2002. When considering the infrastructure of the K-pop music industry as a system of cultural production, album cover design and image production are heavily affected by the impact factors outlined in the research. The research reveals the push and pull of globalizing forces where the K-pop industry received influence from the United States and Japan, then exported its globalized image abroad to the rest of Asia. Conclusions This research allows for a deeper understanding of album cover design and image production as integral facets of the K-pop music industry. The study explains the specific influences, particularly from African American and Japanese sources, that shaped the industry as a system, as well as the resulting designs and images of artists. The conclusive aim of this research is to expand the scholarship on K-pop to include design and image production as significant areas of research.
행위자 네트워크 이론을 기반으로 한 케이팝 상품 분석 - 포토카드와 케이팝 팬을 중심으로
채희준,김상규 한국예술종합학교 한국예술연구소 2023 한국예술연구 Vol.- No.40
The K-pop music industry has had global success on many levels, but notably it has shown increasing physical album sales that appears to counter media trends. The photo card is a unique part of the physical album package sold by K-pop groups and their record labels. The photo card has become an incredibly successful merchandising product within the K-pop music industry, motivating feverish consumption amongst fans. This presents a peculiar phenomenon within the music industry, which continues to struggle to motivate profitable physical album sales. This study attempts to explore the symbolic significance of photo cards within the K-pop product infrastructure and shed light on the motivations of fans in collecting photo cards. To examine this subject, the research applies the Actor Network Theory as a method to examine the material culture of K-pop merchandise, and the particular behaviors that fans exhibit when collecting photo cards. 케이팝 음악 산업은 여러 측면에서 세계적인 성공을 거두었는데 특히 미디어 트렌드를 역전시킬 만큼 실물 앨범 판매량이 증가하고 있다. 포토카드는 케이팝 그룹과 음반사에서 판매하는 실물 앨범 패키지의 독특한 부분이다. 포토카드는 케이팝 음악 산업에서 매우 성공적인 머천다이징 상품이 되었으며 팬들 사이에서 소비 열풍을 불러일으키고 있다. 이는 수익성 있는 실물 앨범 판매를 유도하는 데 어려움을 겪고 있는 음악 산업 내에서 특이한 현상으로 나타난다. 본 연구는 케이팝 상품 인프라 내에서 포토카드가 갖는 상징적 의미를 탐구하고 팬들이 포토카드를 수집하는 동기를 조명하고자 한다. 이를 위해 본 연구에서는 행위자 네트워크 이론을 적용하여 케이팝 굿즈의 물질적 문화와 팬들이 포토카드를 수집할 때 보이는 특정 행동을 조사한다.
프랜차이즈 본부의 가맹비용이 기업영속성에 미치는 영향: 가맹만족과 경영성과의 순차 매개효과

Purpose: This study is to investigate the causal relationship between franchise headquarters’ franchise cost and franchise satisfaction and management performance, and to verify the structural relationship between franchise cost and corporate permanence. Research design, data and methodology: The data were collected from 200 medium-sized franchisees in Seoul and analyzed using confirmatory factor analysis (CFA) to test the validity of the measurement model and the structural equation model (SEM) to identify the impact of franchise costs on corporate performance with the Amos 28.0 program. Result: Franchise costs were found to have a negative effect on franchise satisfaction and corporate permanence. It was confirmed that franchise satisfaction had a significant positive effect on management performance and corporate permanence. Franchise costs had a sequential mediating effect on franchise satisfaction and management performance, which had a significant impact on corporate permanence. Conclusions: This study expanded the theoretical scope by applying the expectation confirmation theory to corporate transactions. In addition, the franchise headquarters proposes ways to create a culture of franchise business with trust by presenting appropriate franchise costs to improve management performance and corporate permanence through franchise satisfaction.
MOTIVICITY OF THE MIXED HODGE STRUCTURE OF SOME DEGENERATIONS OF CURVES
채희준,전병흡 대한수학회 2010 대한수학회보 Vol.47 No.3
We consider a degeneration of genus 2 curves, which is opposite to maximal degeneration in a sense. Such a degeneration of curves yields a variation of mixed Hodge structure with monodromy weight filtration. The mixed Hodge structure at each fibre, which is different from the limit mixed Hodge structure of Schmid and Steenbrink, can be realized as H1 of a noncompact singular elliptic curve. We also prove that the pull back of the above variation of mixed Hodge structure to a double cover of the base space comes from a family of noncompact singular elliptic curves.
