A design file can get larger in size as the complexity of the target object increases. A large design file may reside in a large parallel computing system, such as cloud computing systems, and many designers may work concurrently on the same design file. In such a case, it is obvious that we need some kind of protection mechanism so that each user can access only the area of the file he or she is entitled to. Two approaches can be taken for this problem: one is the traditional access control mechanisms and the other encryption techniques. We take the latter approach to ensure the safety of the file even in public domain such as clouding systems, and in this paper, we suggest an encryption scheme for a file where the file is encrypted in multi-layer so that each user is allowed to access the file only at the layer for which the user has the proper access right. Each layer of the file is encrypted with different keys and these keys are exposed only to those who have the right access permit. The paper explains the necessary file format to achieve this goal and discusses the file manipulation functions to handle this new file format.

HRD professionals should be able to contribute to performance improvement by focusing on strategic business partner activities such as planning, organizational development, and organizational design. Taking a systems view is important in the development of strategy because simply offering specific interventions neither changes nor improves the fundamental systems of an organization. In order to guide the management of organizations as systems, HRD professionals need to not only deal with resistance to change in solution implementation but also identify quantifiable measures to judge the effectiveness of implemented solutions with partnerships with relevant stakeholders. HRD professionals are particularly required to play a critical role in aligning process goals, process design, and process management to improve performance. Adjusting human performance policies and practices to local cultural differences is also among the urgent tasks for HRD professionals.

Teaching and learning research is essential to prepare for the era of the 4th industrial revolution. We must strengthen the creative educational capabilities of prospective teachers by improving the curriculum and teaching-learning model of teacher training colleges. Future education should foster creative thinking based on communication and collaboration. In this study, we improved the future teaching and learning model and applied it to actual classes. In addition, we verified the effectiveness by conducting pre- and post-surveys on the capabilities of future creative teachers. The survey consists of common satisfaction questions and questions about future creative teacher capabilities. As a result of the analysis, we confirmed that the capacity of future creative teachers increased.

The globalization of Korean culture has spurred a steady increase in the participation of domestic fashion designers in global performance art. This study analyzes the formal elements of stage costume designs by fashion designers, and further evaluates the impact of these designers' aesthetic philosophies on overall performance. This analysis seeks to provide a foundation for the development of new directionality in performance art, with an enhanced competitiveness derived from diversity and creativity. The scope of this research spans 15 performances and eight fashion designers' works in the post-2010s era. These performances are characterized by their break from traditional artistic norms, illustrating the modernization of the performing arts and reflecting the designers' aesthetic philosophies. This modernization incorporates inspirations drawn from a diverse selection of movements, such as fusion, culture clash, kitsch, and minimal avant-garde. As a result, in combination with a pure reflection of the designers' aesthetics, these designs heighten overall performance, suggest a new direction for traditional performance art, tap into a popular sensibility to expand communication to a wider audience, and push the boundaries of tradition through artistic innovation.

물류 프로세스내의 상황결정은 전문적인 물류지원 연구의 중요한 목표이다. CBR(Case Based Reasoning)는 기존의 사건이나 경험으로 현재 발생한 문제의 해결책을 발견하기 위한 기술이다. CBR의 주요 역할은 현재 사건에 있는 문제의 상태를 인식하며 이 사건과 유사한 기존 사건 중의 하나를 통하여 현재 사건의 해결책을 추론함으로써 기존 시스템을 업데이트하는 것이다. 이러한 과정에서 가장 중요한 이슈는 유용한 사례베이스를 구축하는 것이다. 온토로지를 이용하여 상황을 모델화하면, 여러 개체들이 협업하에서 상황에 대한 인식을 공유할 수 있게 된다. 본 논문에서는 CBR 사례베이스 구축을 위한 참조로서 물류 온토로지를 디자인하였다.

컴퓨터 프로그래밍에 의해 특정 모티브 이미지를 기반으로 다양한 규칙과 불규칙요인을 포함한 동적구성을 완성한다. 완성된 동적구성에서 타임 슬라이스를 통해 다수의 이미지컷을 생성하고 이를 단독 또는 혼합하여 그래픽디자인의 소스로 사용하는 등 예술적으로 활용하는 것이 본 연구의 목적이다. 이러한 방법을 '프로그래밍아트'라고 칭하고자 한다. 첫번째 시도한 모티브는 색동이다. 조선 복식에서 기쁨과 즐거움의 표현으로 사용된 원색들은 배열의 질서를 갖춰 색동의 형식을 취함으로써 원색 조화의 미를 보여준다. 이제까지 "탈 색동화에 의한 디자인 전개"는 색동의 조형요소를 다양하게 변형시키는 것으로 여러 분야의 디자이너들에 의해 색동의 색이나 색 너비등의 변형으로 시도되고 있다. 색동의 색상과 이미지틀을 유지하면서 변형할 영역을 도출하여 프로그래밍하였고, 몇가지 유형의 그래픽 재료를 생산하고 이를 재가공하였다. 예술의 창의적 과정에서 프로그래밍을 통한 자동화 영역을 찾는 것은 다소 불합리해 보이지만, 창의적인 작업과정을 세부적으로 나누면서 규칙적 영역을 발굴하거나, 그 영역 내에서도 인터랙션을 통해 인간의 의지가 반영될 수 있다. 이는 인간과 컴퓨터가 공조하여 창의성을 추구함으로써 컴퓨터를 또 하나의 생명체로 간주해가는 미래사회 협업의 새로운 유형의 시도라 생각한다.

In the 21st century, the 4th Industrial Revolution is in need of talented people who are equipped with experience and knowledge of various industries. Each university operates a capstone design to nurture the talent needed for practical work and attaches importance to the industry. However, since students in a single major plan as team members, there are limitations in current market situation and environmental awareness, marketing and design. In order to improve the shortcomings of the capstone design, which is carried out at the center level, engineering and design need to collaborate with each other without focusing only on the technical part. In this study, the researcher introduces the engineering and design linkage cases of the Capstone Design Program operated by the Department of Media Software and seeks to improve them. First, the educational purpose and operation plan of capstone design in the engineering field was reviewed and the improvement plan was suggested based on the result of the program case operated by the researcher.

The present investigation is concerned chiefly with new curriculum development at the Department of Mechanical System & Design Engineering at Hongik University with the aim of enhancing creativity, team working and communication capability which modern engineering education is emphasizing on. 'Mechanical System & Design Engineering' department equipped with new curriculum emphasizing engineering design is new name for mechanical engineering department in Hongik University. To meet radically changing environment and demands of industries toward engineering education, the department has shifted its focus from analog-based and machine-centered hard approach to digital-based and human-centered soft approach. Three new programs of Introduction to Mechanical System & Design Engineering, Creative Engineering Design and Product Design emphasize hands-on experiences through project-based team working. Sketch model and prototype making process is strongly emphasized and cardboard, poly styrene foam and foam core plate are provided as working material instead of traditional hard engineering material such as metals material because these three programs focus more on creative idea generation and dynamic communication among team members rather than the end results. With generative, visual and concrete experiences that can compensate existing engineering classes with traditional focus on analytic, mathematical and reasoning, hands-on experiences can play a significant role for engineering students to develop creative thinking and engineering sense needed to face ill-defined real-world design problems they are expected to encounter upon graduation.
