Advances in science and technology have led the development of the times, and provide abundant technological means, new tools, and new angles of thought to art and new media, and become an important driving force for creativity and rigidity in art. This study, starting from the trend of convergence creativity between art and science and technology, focuses on the new characteristics of new media art, and combines examples of works in several areas such as characteristics. It has a certain reference value for understanding the characteristics of the times and its development trend to deeply grasp the current new media art while analyzing it in detail.

전통적인 멀티캐스트는 유니캐스트 방식에 비해 네크워크자원 이용 및 전송 측면에서 매우 효율적이지만 라우터에서 각 멀티캐스트 그룹의 상태 유지, 복잡한 네트워크 운영, 멀티캐스트를 위한 준비된 IP 주소 공간의 부족, 네트워크 변경의 제한 등의 문제점이 제기되어 왔다. 본 연구에서는 전통적인 멀티캐스트의 문제점을 최소화하기 위하여 효율적인 호스트 기반의 멀티캐스트 트리 알고리즘을 적용하여 호스트 기반 멀티캐스트 시스템을 설계 한다.

We demonstrate that the finite rate of dielectric relaxation in liquid crystals which has been ignored previously causes profound effects in the fast dielectric reorientation of the director. The phenomenon is relevant for submillisecond switching of the director when the switching rate approaches the rate of dielectric relaxation through the reorientation of the molecular dipoles. A submillisecond switching ($15-400\;{\mu}s$ for an optical retardation shift $0.3-2.2\;{\mu}m$ in $10-15\;{\mu}m$ thick cells) is demonstrated for dual frequency nematic cells with high pretilt that maximizes the dielectric torque acting on the director. We propose the theory of dielectric response in which the electric displacement depends not only on the present (as in the standard theory) but also on the past values of electric field and director. We design an experiment in which the standard "instantaneous" model and our model predict effects of opposite signs; the experimental data support the latter model.

초해상은 저해상도의 영상을 고해상도 영상으로 합성하는 기술이다. 이 기술에 딥러닝이 적용되어, 2014년에는 SRCNN(Super Resolution Convolutional Neural Network) 모델이 발표됐다. 이후에는 SRCAE(Super Resolution Convolutional Autoencoders)와 GAN(Generative Adversarial Networks)을 기반으로 한 SRGAN(Super Resolution Generative Adversarial Networks) 등, SRCNN의 성능을 능가하는 모델들이 발표됐다. ESRGAN(Enhanced Super Resolution Generative Adversarial Networks)은 SRGAN 모델의 성능을 개선했지만, 완벽한 성능을 내지 못하는 문제점이 있다. 이에 본 논문에서는 판별자(Discriminator) 구조를 변경하여 ESRGAN의 성능을 개선한다. 실험 결과, 제안하는 모델이 ESRGAN보다 더 높은 성능을 보일 것으로 기대된다.

In this research, hybrid method with case-based reasoning and rule-based reasoning is applied. Using case-based reasoning, design experts'experience and know-how are effectively represented in order to obtain a proper configuration of midship section in the initial ship design stage. Since there is not sufficient domain knowledge available to us, traditional case-adaptation algorithms cannot be applied to our problem, i.e., creating the configuration of midship section. Thus, new case-adaptation algorithms not requiring any domain knowledge are developed antral applied to our problem. Using the knowledge representation of DnV rules, rule-based reasoning can perform deductive inference in order to obtain the scantling of midship section efficiently. The results from the case-based reasoning and the rule-based reasoning are examined by comparing the results with various conventional methods. And the reasonability of our results is verified by comparing the results wish actual values from parent ship.

The emergence of environmental and social issues has led to global discussions for the realization of sustainable development. The purpose of this study is to propose a method of sustainable fashion design using waste Hanbok, focusing on men's Hanbok with cultural values. The study utilizes literature research and fashion design development. From the literature study, reform was judged to be a higher concept encompassing reduction, recycling, and upcycling. Reduction is a design method through removal, and recycling design transforms from its original form into a completely different product. Upcycling design focuses on improvement and change in functionality. Accordingly, nine redesigns using men's Hanbok were developed from which three were produced. Consequently, the reduction design demonstrated a small range of variation without changing the item, and cultural sustainability was confirmed through the design that removed the components and recombined the Hanbok. Second, recycling redesign can be reconstituted into a different item. Third, upcycling enables various designs through module assembly, which prolongs the lifespan of the product and confirms its value as a raw material for waste Hanbok. This study is meaningful in realizing sustainable fashion and suggesting practical measures for the sustainability of Korean traditional culture and creative fashion design planning.

This study reviews recently developed perspectives within Science and Technology Studies (STS) and engineering education including engineering ethics and engineering design, focusing on defining why interdisciplinary collaboration between those two areas is required and how it can be realized. The disconnection between those areas is closely related to the chronic diseases that has brought the mono-disciplinary, segmented educational system of 20th century: fragmented perception of reality and gradual loss of academic influence. This study consists of two sections: the first section reviews new movements among STS, engineering ethics and engineering design; the second section analyses how their combination is developing and what significance it represents. Recently, some scholars attach more importance to scalable scholarship of STS, that is, strategic expansion of the range of STS. This kind of attempts is gradually producing satisfactory results as it is combined with innovative efforts arising from the field of engineering education. This study emphasizes that, when STS and engineering education are combined and interact more with each other, it will broaden our prospects about engineering and society; it will, particularly, contribute to enhance our engineering education.

오늘날 인터넷 환경에서의 망은 유무선의 환경이 통합된 하나의 망으로 달수 있다. 일반적인 TCP에서는 무선망에서의 핸드오프나 비트오류 등으로 인한 패킷 손실이 발생하는 경우에도 흔잡제어 알고리즘으로 손실된 패킷을 복구하게 되며 이러한 복구는 혼잡윈도우를 줄이게 됨으로 인해 현저히 TCP의 처리량을 감소시키게 된다. 본 논문에서는 유무선이 통합된 망에서 데이터 전송 효율을 높일 수 있는 알고리즘을 제시하고자 한다. 이 알고리즘에서는 홈서버를 사용하여 무선망에서 발생한 패킷 손실이 종단간의 재전송이 아닌 홈서버에서 지역 재전송을 함으로써 유무선망의 부하를 줄이고 흔잡제어 알고리즘이 실행되는 것을 방지하여 TCP의 성능향상을 가져올 수 있으며 캐쉬메모리에 재전송 패킷을 보관하여 재전송함으로써 보다 빠른 재전송효과를 얻을 수 있다.
