The abstract should summarize the contents of the paper and written below the author information. Use the word "Abstract" as the title, in 12-point Times New Roman, boldface type, italicized, centered relative to the column, initially capitalized, fixed-spacing at 13 pt., 12 pt. spacing before the text and 6 pt. after. The abstract content is to be in 11-point, italicized, single spaced type. Leave one blank line after the abstract, and then begin the keywords. All manuscripts must be in English. When it comes to the issue of "virtual and real" in traditional Chinese painting, the first impression is to describe the problems of painting strokes and ink, layout of pictures, etc., but it runs through the initial conception of the work, creation in the middle and aesthetic appreciation of the work. It exists in the whole process of artistic creation and appreciation. In essence, it is a problem of aesthetic thinking and philosophical thinking. Because the traditional Chinese painting theory is influenced by Taoism, when the concept of "virtual and real" is implemented in the specific picture of Chinese painting, it is contained in the specific shape of "physics", that is, the painting theory research of "blank space" in the picture. Based on the traditional Taoist philosophy of China, this paper takes the "virtual and real" view in Lao Zhuang's thought as the research object, deeply analyzes and compares its relationship with the "virtual and real" in Chinese landscape painting, and finds out their artistic spirit, essential characteristics and how to present them. This paper mainly discusses the internal relationship between Taoist philosophy and "virtual and real" in Chinese landscape painting from the following aspects. The introduction expounds the origin, purpose, significance, innovation and research methods of the topic. This paper analyzes the philosophical thoughts about landscape in the philosophical thoughts represented by Lao Tzu and Zhuangzi. The development of Chinese traditional aesthetics theory is closely related to Taoist philosophy, which has laid the foundation and pointed out the direction for the development of Chinese painting theory since ancient times. It also discusses the influence of the Taoist philosophy of "the combination of the virtual and real" on the emergence and development of the artistic conception of landscape painting. Firstly, through the analysis of the artistic conception of landscape painting and its constituent factors, it is pointed out that the artistic conception is affected by the personality and the painting artistic conception. Secondly, through the Taoist thought of "the combination of the virtual and real" in landscape painting, so as to reflect that it is the source of the artistic conception of Chinese landscape painting. It is the unique spiritual concept of "Yin and Yang" and "virtual and real" that creates the unique "blank space" aesthetic realm of Chinese painting in the composition of the picture. Finally, it focuses on the "nothingness" in Taoist philosophy and the "blank space" in Chinese landscape painting. The connotation of the "blank space" in Chinese painting exceeds its own expressive significance, which makes the picture form the aesthetic principle of emotional blending, virtual and real combination and dynamic and static integration. Through the "blank space", it deepens the artistic characteristics of the picture and sublimates the expression of "form" in Chinese painting.

This paper presents the bytecode-to-SIL translator which enables the execution of the java program in EVM(Embedded Virtual Machine) environment without JVM(java Virtual Machine), translating bytecodes produced by compiling java programs into SIL(Standard Intermediate Language) codes. EVM, what we are now developing, is a virtual machine solution that can download and execute dynamic application programs written in sequential languages like C language as well as object oriented languages such as C#, Java, etc. EVM is a virtual machine mounted on embedded systems such as mobile device, set-top box, or digital TV, and converts the application program into SIL, an assembly language symbolic form, and execute it. SIL is a virtual machine code for embedded systems, based on the analysis of existing virtual machine codes such as bytecode, MSIL, etc. SIL has such features as to accommodate various programming languages, and in particularly has an operation code set to accept both object-oriented languages and sequential languages. After compiling, a program written in java language is converted to bytecode, and also executed by JVM platform but not in other platform such as .NET, EVM platform. For this reason, we designed and implemented the bytecode-to-SIL translator system for programs written in java language to be executed in the EVM platform without JVM. This work improves the execution speed of programs, enhances the productivity, and provides an environment for programmers to execute application programs at various platforms.

Training is one of the representative application fields of virtual reality technology where users can have virtual experience in a training task and working environment. Widely used in the medical and military fields, virtual-reality-based training systems are also useful in industrial fields, such as the aerospace industry, since they show superiority over real training environments in terms of accessibility, safety, and cost. The shipbuilding industry is known as a labor-intensive industry that demands a lot of skilled workers. In particular, painting jobs in the shipbuilding industry require a continuous supplement of human resources since many workers leave due to the poor working environment. In this paper, the authors present a virtual-reality-based training system for spray painting tasks in the shipbuilding industry. The design issues and implementation details of the training system are described, and also its advantages and shortcomings are discussed based on use cases in actual work fields.

The revolution of digital fashion continues along with the development of technology. In particular, after COVID-19, fashion design development, exhibitions, and fashion shows using the metaverse space are being actively developed. In particular, as research on 3D virtual costumes becomes active, creative ideas are needed to develop creative virtual costumes. The purpose of this study is to examine the geometric formative characteristics of constructivism in art and fashion design and to develop 3D virtual works using them. Geometric form is a logical and rational basic form that includes the order of nature as an artistic material that has been constantly studied along with the creation of mankind a long time ago, and it has become a motif of many artworks and fashion. In this paper, we studied the application of the costume design of geometric shapes according to the 3D Clo, virtual-wear production software, and understood the effect of the combination of geometric shapes on costume styling. As the formative characteristics of constructivist art, three types of overlap, asymmetry, and simplicity were derived, and the geometric form was visually simple, clear, and concise. The first work produced virtual costumes that reflected the overlapping elements of constructivism. The second costume was produced by reflecting the asymmetric formative characteristics of constructivism. The third costume was a jacket that applied the simplicity of constructivist art.

가상환경이란 사용자들에게 실감나는 감각적 체험과 인터랙션을 제공하여 마치 실제 공간에 있는 것 같은 느낌을 주는 멀티미디어 환경을 일컫는다. 이런 가상환경에 일반 사용자들에게 친숙한 2차원 인터페이스를 활용하여 사용자 인터랙션을 쉽게 도와주는 연구가 많았는데, 주로 특정 가상환경에서만 사용할 수 있고 일반적으로 적용하기 어려운 문제가 있었다. 이런 점을 개선하기 위해 가상환경을 위한 2차원 사용자 인터페이스 저작 프레임워크 개발 시도가 있었으나 사용성이나 유연성이 부족했다. 본 연구에서는 XML과 스크립트 언어를 활용하고 동적으로 모듈을 적재하고 설정하는 기능과 이벤트 처리 메커니즘을 제공하여 사용성과 유연성을 지원하는 새로운 가상현실 인터페이스 제작 툴킷인 HIVE 프레임워크를 만들었다. 본 논문에서는 먼저 HIVE프레임워크에 대해 설명하고, HIVE를 이용하여 다양한 인터페이스를 개발한 예를 보여주며, 향후 연구방향에 대해 논한다.

Fault management of virtualized network environments using user-driven network provisioning systems (NPSs) is crucial for guaranteeing seamless virtual network services irrespective of physical infrastructure impairment. The network service interface (NSI) of the Open Grid Forum reflects the need for a common standard management API for the reservation and provisioning of user-driven virtual circuits (VCs) across global networks. NSI-based NPSs (that is, network service agents) can be used to compose user-driven VCs for mission-critical applications in a dynamic multi-domain. In this article, we first attempt to outline the design issues and challenges faced when attempting to provide mission-critical applications using dynamic VCs with a protection that is both user-driven and trustworthy in a dynamic multi-domain environment, to motivate work in this area of research. We also survey representative works that address inter-domain VC protection and qualitatively evaluate them and current NSI against the issues and challenges.
