In this study, a general perturbation method is presented to reanalysis dynamic response of base-isolated systems. The perturbation is expanded to general order and which provide the formulation of perturbed solutions. in which eigensolutions of non-modified system are treated as unperturbed solutions. The accuracy of present method is tested using a 2-DOF system with isolator, where the stiffness and damping coefficients of isolator are changed, respectively, The reanalyzed eigensolutions and response using perturbed solutions are successfully approached to exact ones after just first perturbation. Supposing the practical criterion as ${\pm}5%$ error, the modification range of -50%~30% from original system can be allowed for the first order perturbation. Using higher order solutions, the applicable range will be wide.

현재 증강현실 인터페이스 상의 정보시각화는 공간과 사용자 그리고, 구조를 적절히 반영하여 제공되고 있지 못한 실정이다. 증강현실이 만들어낸 현실과 가상의 병치된 공간 안에서, 인터페이스는 우리가 생활하는 물리적 공간 그 자체가 된다. 따라서 증강현실을 위한 UI를 구조화 할 때, 기존 인터페이스가 가진 특성을 AR공간안에서 재해석 할 필요가 있다. 본 연구에서는 증강현실 상 지능적 정보 시각화에 있어 고려해야 할 요소를 정보디자인의 설계 과정을 토대로 추출하여 AR공간에 특화된 UI구축의 방법론으로 제안하고자 한다.

애니메이션 영웅 캐릭터는 캐릭터의 한 카테고리로서 캐릭터 특유의 특징과 함께 전통적 이데올로기를 암묵적으로 전달하고 있다. 이들 애니메이션 영웅이 전달하는 전통적 메시지는 문화적 개성에 대한 심벌을 재해석하여 관객들에게 전통문화가 거부감없이 쉽게 받아들여지도록 하는 것이다. 애니메이션 <백사(White Snake, 2019)>는 중국에서 잘 알려진 백소정과 허선의 사랑이야기를 소재로 한것으로서 전통사상과 전통의상을 살리면서도 스토리텔링과 이미지 컨셉, 애니메이팅등의 시각적 요소들을 글로벌한 공감대를 얻을 수 있도록 노력한 흔적들을 보여주고 있다. 본문에서는 동양 애니메이션에서의 히어로 캐릭터와 디즈니 캐릭터 간의 차이점과 그 가치를 애니메이션<백사>를 통해 분석해보고 이를 통해 애니메이션 창작에 미치는 영향과 역할을 도출해보려 하였다.

In 2017, 100 aftershocks with a magnitude of 2.0~3.0 and 615 minor earthquakes in Pohang in Korea caused the collapse and destruction of aggregate, tile, glass, and other structural components of multi-family houses constructed as finishing materials for buildings, causing damage to vehicles and casualties. Based on this factor, seismic design standards were established for non-structural elements of buildings that were applied only to past structures. Therefore, this study reinterpreted various vibration response spectra transmitted to waterproof layers as well as the definition and concept of the waterproof layer demand response spectrum derived by developing various vibration response test evaluation devices through a new testing apparatus.

This study investigates what older adults give meaning of ageism with relation to their self-identity. The main findings are as follows. The participants' response to daily life ageism is divided in four types: 'denial', 'evasion', 'acceptance', 'problematic proposal', and 'isolation'. In conclusion, this study contributes to understanding ageism in-depth. The findings of this study discover tension and suppression within society regarding ageism from the perspectives of the older participants, and reveal the latent dimension which is not caught with the language.

This study aims to explore a biological interpretation of farming practices mentioned in 'Sallimgyeongje(山林經濟)', an agricultural literature published in late 18C, in order to substantiate its scientific practicality and suggest the sustainable direction of modern agriculture. First, the research revealed that weeds and pests were effectively controlled by interspecies interactions such as allelopathy, mutualism, and interplanting. Second, qualified seeds were selected without dependence on chemical treatments by using specific gravity and cold water immersion. Third, the literature proposed plowing methods based on the properties of the soil, which implicated an establishment of healthy landscape mosaic by imitating the succession and introducing the moderate disturbance. Fourth, the genotypes of 37 native rice varieties were speculated based on six phenotype standards, and some of them are expected to have high nutritional value and abiotic stress resistance.

The present study is about a brand development strategy that utilizes Korean traditional patterns. The global culturenomics phenomenon confirms the value of the cultural aspects of design when a national brand is established. People succeed with their unique aesthetic sense and reinterpret it in a modern view, and this design acts as today's national brands. In this way, people used traditional patterns and original designs, along with regional characteristics and formative style, in developing their designs. However, due to recent changes in the global environment, modern people live in an "untact" world, and consumption culture shifted toward online marketing. In this environment, where one is isolated from social activities, there needs to be a strong image that can dramatically change the mood of one's home. I would like to re-examine the Dan-Chung pattern, whose painting depends on the aesthetic characteristics of architecture to protect the wooden members of the framework in traditional architecture. The pattern and color of Dan-Chung, coated in traditional architecture, differs by the type of construction used, which includes a palace, a Buddhist temple, and a Confucianism Dan Chung. The Geummoon pattern contains aesthetic factors to add solemnity to the Main Buddhist Halls, which contain Buddha. This is a new medium that continues the current traditions instead of remaining in the past. Among different Dan Chung patterns, Geummoon has magnificent decoration consisting of the highest grade materials and unique composition; therefore, it is suitable to be reinterpreted in modern terms. The same pattern can be interpreted in different ways with different colors, so there is a great aesthetic impression in the Geummoon pattern. The value of preservation for exploration and theoretical study of the traditional pattern is important, but recreating the pattern into modern formative art can present a new angle of view and national brand, bearing pride in our cultural assets. The study used multidimensional molding methods for realistic presentation after going through the two-dimensional design process. The significant value of Korean molding beauty which hangs onto the past will play a crucial role in establishing our national brand.

This paper critically examines the role and function of religion prior to the full-out advent of the 4th industrial revolution. We can understand 'The vision of Daesoon Jinrihoe (大巡眞理會)' as a mission to foresee and create a prospective figure for a future society in the person of the Lord on High, Jeungsan (甑山) as a religious dimension. However, the existence ground of religion relies on giving positive meaning to the present time after reinterpreting religious doctrine to reflect changing realities. Jeungsan (甑山) said that the age to come is 'the age of the human majesty (人尊)'. This means that humans will take the lead and control the revolution of scientific technology to progress and benefit humanity. Problems such as 'human alienatio', 'increased polarization', and 'destruction of the environment' still arise and deepen because the motive of 'the Industrial Revolution' was built upon 'knowledge' within the context of a Knowledge-Based Society. Therefore, we can say that the role of religion will newly rise to the forefront in the era of the 4th industrial revolution. Consequently, religion should face matters squarely and suggest viable alternatives. This paper deals with reinterpreting the concept of 'the resolution of grievances for mutual beneficence (解冤相生)', one of the four teachings of Daesoon Jinrihoe, within the context of the coming era of the 4th industrial revolution. My research is divided into the following three parts: First, I determined the teachings of Daesoon Jinrihoe and the original meaning of 'the resolution of grievances for mutual beneficence', and then I disclosed the way we can reinterpret the general meaning of this concept for application in the ear of the 4th industrial revolution. Second, from the perspective of the religious dimension, I inquired into factors regarding alienation and conflict in the era of the 4th industrial revolution. I focused on human alienation from labor, identity confusion, potential conflicts between humans and post-humans, and the characteristics of the 4th industrial revolution. Third, I examined potential cures for alienation and conflict through the principle of the resolution of grievances for mutual beneficence. I tried to enlarge the interpretive prospects of Daesoon's main teaching in light of the era of the 4th industrial revolution through a new interpretation and application that employs the concept of 'the resolution of grievances for mutual beneficence (解冤相生)' in order to cure the alienation and conflict.
