With improving computing performance, various digital platforms are being developed to enable easily utilization of high-performance computing environments. EDISON 1.0 is an online simulation platform widely used in computational science and engineering education. As the research paradigm changes, the demand for developing the EDISON 1.0 platform centered on simulation into the EDISON 2.0 platform centered on data and artificial intelligence is growing. Herein, a data framework, a core module for data-centric research on EDISON 2.0 digital platform, is proposed. The proposed data framework provides the following three functions. First, it provides a data repository suitable for the data lifecycle to increase research reproducibility. Second, it provides a new data model that can integrate, manage, search, and utilize heterogeneous data to support a data-driven interdisciplinary convergence research environment. Finally, it provides an exploratory data analysis (EDA) service and data enrichment using an AI model, both developed to strengthen data reliability and maximize the efficiency and effectiveness of research endeavors. Using the EDISON 2.0 data framework, researchers can conduct interdisciplinary convergence research using heterogeneous data and easily perform data pre-processing through the web-based UI. Further, it presents the opportunity to leverage the derived data obtained through AI technology to gain insights and create new research topics.

Over the past ten years, numerous industries have undergone upheavals that have significantly altered how businesses interact with their clients and how goods are created and produced bySMEs. Many cutting-edge technologies have recently been created and implemented to enhance business models, facilitate sustainability features for organizations, and boost business capabilities. This essay seeks to understand how digital entrepreneurship functions in developing nations. The results of this study show the effectiveness of digital transformation in the context of SMEs is greatly influenced by aspects including the change of managerial intensity and the involvement and perception of workers, customers, and shareholders. One of the needs that business owners showcased in this study in terms of digitization is infrastructure resources to support digitization such as devices, the Internet, and funds, but also the ability to use digital media for business development. Practical skills that business people want to learn such as product design and management of their social media accounts. There are also aspects of time and self-motivation of the business actor that can speed up or slow down the digitization process. Finally, government support that is structured in encouraging MSMEs is also one of the supporters and drivers of digitalization in the blue economy.

디지털 애니메이션의 환영(幻影-illusion) 이미지를 만드는 과정은 테크놀로지의 수공예적인 수작업(手作業) 즉, 애니메이션 과정, 이미지의 덧붙임, 보정(補整) 등을 통해 만들어진다. 본 논문은 디지털 애니메이션이 전통 예술의 수공예적인 측면을 디지털 제작 과정으로 부활시켜 새로운 예술 개념을 획득하고 있음을 주장하고 있다. 이를 구체화하기 위해서 본 논문은 다음의 단계로 이루어진다. 첫 째는 영화의 복제와 혼성이다. 예술의 '아우라'를 강조 해왔던 예술사에서 기계에 의한 복제는 피할 수 없는 것이 되었고, 디지털로 저장된 다양한 그림 정보와 짜깁기된 영상작업들은 복제와 혼성으로 새로운 영상 작업을 쉽게 할 수 있는 계기가 되었다. 둘째, 디지털 애니메이션의 예술 영역의 확장이다. 이제 디지털 애니메이션은 극사실의 환영성을 통해 새로운 창조적 예술로 인정받고 있다. 결과적으로, 디지털 애니메이션의 제작과정으로 과거의 미디어가 이루지 못한 상상력을 복원하는 새로운 미디어 예술의 특성을 보여주면서 디지털 애니메이션의 새로운 예술로써의 가능성을 획득하고 있다

이 논문에서 필자는 가장 오래된 남성폭력의 기술화 버전이라 할 수 있는 디지털 성폭력에 대한 철학적 담론을 개진해보고자 한다. 첫 번째로 불법 도촬 카메라의 전방위적 공간성의 작동방식과 디지털 데이터 베이스로 전환된 새로운 시간성의 구조를 분석할 것이다. 나아가 디지털 성폭력과 사이버 성폭력 개념이 혼용되어 사용되고 있는 현재 담론지형에 개입해 들어가 볼 것이다. 두 번째로 정보통신기술의 발달과 사물 인터넷에 기반한 초연결성을 통해, 불법 도촬 카메라의 설치와 촬영이라는 물리적 공간에서의 활동이 사이버 공간이라는 디지털 매트릭스로 즉각 편입이 가능해짐으로써 여성신체이미지가 디지털 재화로 기능하는 측면을 분석할 것이다. 세 번째로 필자는 디지털 성폭력이라는 피해경험을 재언어화하기 위해, 새로운 감정구조를 고안해보고자 한다. 즉 성적 수치심이 아닌, 성적 불쾌감, 사회적 분노감이라는 다층화된 감정구조로의 이행을 통해, 피해자다움이라는 프레임에 갇힌 약자의 전형화에서 벗어나도록 한다. 새로운 감정 양식은 저항적, 도전적 신체 감응 양식의 창출을 도모함으로써 더 이상 사라져야할 자는 피해자가 아닌, 가해자들임을, 수치의 몫은 피해자가 아닌 가해자에게 부과해야하는 것임을 낱낱이 드러낼 것이다. 나아가 디지털 성폭력에 대한 대항실천은 한 개인의 문제가 아닌 공공성의 문제이자 정치적 시민권의 실행에 관한 문제로서 접근되어야한다.

Advances in the technology of computational design are giving architects and engineers the opportunity to analyze buildings with complex geometries. This study explores the optimization and automation process using the parametric design method, and uses digital tools to achieve surface representation and panelization for curved shaped office buildings. In this paper, we propose parametric algorithms of dimensional and geometric constraints using the Knowledge-ware scripts embedded in Gehry Technologies' Digital Project. The knowledge-based design methods proposed in this study can be used to systemize the knowledge possessed by experts in the form of data. Such knowledge is required to promote collaboration between designers and engineers in the process of CAD/CAE/CAM. The aim of this study is to integrate the process into design, which establishes an integrated process. This integration enables two-way feedback between design and construction data by combining the methods used in designing, engineering, and construction.

The success of movie 'Avatar' make people be interested in 3D stereoscopic movie, and government and 3D industry acknowledge that it is another opportunity to develop 3D market since 1920s. However, despite much interest little research to evaluate the effect of 3D stereoscopic exists. The present research aimed to disclose 3D effect compared to 2D by assumption of the importance of 3D stereoscopic and little evaluation to that as well. When audience are exposed to 3D stereoscopic, many outcomes are supposed to be differentiated from when to 2D. From this hypothesis, this paper examined mood, attitude, and presence as dependent variables. Using polarized stereoscopic projection display, 30 participants watched 2D and another 30 watched 3D stereoscopic movie which were the same content. On conclusion, the two groups were not significantly different and this involved much insight.

According to the statistics revealed by Bank of Korea on March, 2007, Internet banking transactions outnumbered face-to-face banking services in Korea. Internet banking is becoming essential in every financial service sectors. For people with disabilities, Internet banking is more meaningful because they do not need to visit the bank, thereby saving inconvenient trips. Governments in many countries are working on setting standards and laws on the web accessibility for people with disabilities. Korea government enacted Korea Disability Discrimination Act in 2007. This paper examined the web accessibility compliance of Internet banking sites. Twenty one Internet banking sites were selected from the list in the Korea Federation of Banks's Web sites. We examined four major checkpoints that are considered crucial among the fourteen checkpoints in "Internet Web Contents Accessibility Guidelines" which was amended by Ministry of the information and Communication in 2005. The results showed that all of the twenty one Internet banking sites didn't meet the four major checkpoint requirements. Moreover, only one banking site satisfied alt-text requirement that is considered the most fundamental among the checkpoints.
