Recently, the exhibition industry based on digital archive has been rapidly growing and the industry sees an innovative change with diverse digital archive exhibition venues emerging. Enabling visitors to enjoy new and varied exhibition provides a turning point to the exhibition environment. In today's world where IT (Information Technology) leads social changes, new framework and contents are required to establish digital culture that connects traditional culture with advanced information telecommunications. The objective of this study is to identify factors that influence the audience in a digital archive exhibition venue and to analyze impacts of these factors on exhibition success based on immersion and satisfaction. The study presents a research model that applies significant variables of emotional response theory in which fundamental psychological desire of humans is emphasized. To empirically verify the research model, the author conducted a survey for students of S university in Seoul and for ordinary people who have been to digital archive exhibition venues.

기술의 발전과 가상현실의 세계에서 즐기는 디지털 여가에 대한 수요와 관심이 증대되고 있다. 그런 디지털 여가 활동의 하나로 도심형 디지털 테마파크가 부상하고 있다. 그에 따라 국내에서 다양한 디지털 테마파크가 제작되었지만, 성공적인 흥행을 이루지 못하며 후발 주자를 이끌지 못하고 있다. 따라서 본 논문에서는 이런 현상을 인간의 욕구를 단계에 따라 만족시켜 무아의 경지인 절경경험을 이뤄낸다는 매슬로의 욕구이론과 조셉캠벨의 영웅의 여정단계를 바탕으로 테마파크의 공간 및 게임 요소에 대한 분석을 시도하였다. 본 연구에서 게임기반 테마파크 분석을 위해 사용되는 모형은 향후 다양한 도심형 디지털 테마파크 발전의 초석이 될 것이다.

Various properties of digital covering spaces have been substantially used in studying digital homotopic properties of digital images. In particular, these are so related to the study of a digital fundamental group, a classification of digital images, an automorphism group of a digital covering space and so forth. The goal of the present paper, as a survey article, to speak out utility of digital covering theory. Besides, the present paper recalls that the papers [1, 4, 30] took their own approaches into the study of a digital fundamental group. For instance, they consider the digital fundamental group of the special digital image (X, 4), where X := $SC^{2,8}_4$ which is a simple closed 4-curve with eight elements in $Z^2$, as a group which is isomorphic to an infinite cyclic group such as (Z, +). In spite of this approach, they could not propose any digital topological tools to get the result. Namely, the papers [4, 30] consider a simple closed 4 or 8-curve to be a kind of simple closed curve from the viewpoint of a Hausdorff topological structure, i.e. a continuous analogue induced by an algebraic topological approach. However, in digital topology we need to develop a digital topological tool to calculate a digital fundamental group of a given digital space. Finally, the paper [9] firstly developed the notion of a digital covering space and further, the advanced and simplified version was proposed in [21]. Thus the present paper refers the history and the process of calculating a digital fundamental group by using various tools and some utilities of digital covering spaces. Furthermore, we deal with some parts of the preprint [11] which were not published in a journal (see Theorems 4.3 and 4.4). Finally, the paper suggests an efficient process of the calculation of digital fundamental groups of digital images.

In this paper, as a survey paper, we review many works related to fixed point theory for digital spaces using Lefschetz fixed point theorem, Banach fixed point theorem, Nielsen fixed point theorem and so forth. Besides, we refer some properties of the fixed point property of a digital k-retract.

Purpose The purpose of this study is to identify the role of digital shadow work(DSW) in the psychological mechanism that controls using and purchasing digital device accessories. More specifically, it is to reveal how the digital device user's perception of DSW is formed and how the formed DSW affects purchase and what results it will bring. Design/methodology/approach Ground theory method(GTM), one of qualitative appoaches, is adopted as research methodology. By interviewing total twenty five users, the data are analyzed by open coding amd axis coding. Two core codes are selected by selective coding and interpreted by DSW theory. Findings We find concern for potential DSW and generation of new DSW. Concern for potential DSW lead to the purchase of accessorie which would be supposed to reduce potential DSW. During purchasing accessories, quest type DSW, which provices flow experience and expertise, could be genterated. This means that there would be dynamics of DSW in the purchase process of digital device accessories.

본 논문에서는 그래프 이론에 기초를 둔 GFDD를 사용하여 디지털논리시스템을 구성하는 한가지 방법을 제안하였다. 제안한 방법은 먼저 유한체와 그래프 이론의 수학적 성질을 논의하였으며, 단일변수에 대한 동작영역과 함수영역간의 변환을 용이하게 하기 위한 변환행렬 $\psi$GF(P)(1)과 $\xi$GF(P)(1)을 논의하였다. 그리고 디지털스위칭함수를 구하기 위한 Reed-Muller 확장을 논의하였으며, 이를 다변수인 경우로 확장하기 위해 Kronecker Product를 논의하였다.

This paper was conducted to improve understanding of how the start-up process affects the local community and how young entrepreneurs build and grow their businesses in the process through analysis of young people who started businesses in the region. The research method was conducted through in-depth interviews with 10 young entrepreneurs who started businesses in the western Gyeongsangnam-do region, where population decline is prominent, and the collected data was analyzed through a grounded theory approach to derive common and meaningful themes between each case. proceeded. As a result of the study, insights were derived about the background of entrepreneurs settling in the region, the motivation for starting a business using local resources, the impact of government and local government support, business strategies for sustainable growth, and the entrepreneurs' personal performance. Through this analysis, we hope to provide important insights into the positive impact local entrepreneurship has on the community and how young entrepreneurs contribute to local development.

The purpose of our this research, based on the Media Selection Theory, the Technology Acceptance Model, and the Social Influence Theory, is to investigate the influential factors that affect media selection in banking transactions. Analyses showed that for location sensitive bank window's and ATMs (automatic teller machines), defined as offline-based transaction channels, convenience was the variable affecting media selection. However, in the case of online media not related to location, (phone banking, internet banking, and mobile banking) reliability was the significant variable influencing use. The findings show that banking organizations may benefit from identifying traits of media affecting use, and should differentiate customer services for competitive advantage.

The paper studies an existence problem of a (generalized) universal covering space over a digital wedge with a compatible adjacency. In algebraic topology it is well-known that a connected, locally path connected, semilocally simply connected space has a universal covering space. Unlike this property, in digital covering theory we need to investigate its digital version which remains open.
