This study is about the research of recognition for deinstitutionalization and independent living of the disabled living in residential facilities for the people of family. The survey was conducted in October to September 2018 and 810 cases were used in the final analysis. In this study, we confirmed that about half of the families of groups and those who perceived In accordance with the enactment deinstitutionalization were divided into half. and consent to cegislation, local government efforts, independence, consent to deinstitutionalization family perceptions of disagreement of independence were identified as having no low information provided. These results indicate that there was a lack of provision of services or information related to independent living of the disabled living in residential facilities, and it was confirmed that proper information transfer education on policies and services is needed to have accurate understanding and awareness. In addition, the agreement on legislation, local government efforts, Independence, consent to deinstitutionalization were found to have a significant effect on preparation for independent living. Therefore, it was confirmed that systematic information education support are needed to ensure proper recognition of user's family in residential facilities and to ensure healthy independence of users.

We share the critical mind about the decolonization of Library & Information Science(LIS) and Political Science in Korea. We did a bibliographical study on the decolonization discourse in the Political Science of Korea. Concretely, we traced the decolonization discourse of the scholars of the Political Science in Korea, and wrote their abstracts. Finally, this study provided the general view of their decolonization discourse. This study covers the decolonization discourse from 1945 to 2005. This bibliographical review may show the possibility of communication between LIS and social sciences in Korea, and can support the development of the decolonization discourse in the Political Science of Korea.

Devolatilization characteristics of municipal wood waste were measured by using an isothermal thermogravimetric analyzer(TGA) and discussed. Volatile matter was mainly released at temperatures between $250^{\circ}C$ and $350^{\circ}C$. The volatile content increased with an increase of temperature but levelled off at temperatures ${\geq}527^{\circ}C$. The rate of devolatilization could be expressed by a shrinking particle model which was ruled by the reaction rate. The activation energy ranged from 13.1 to 18.5 kJ/g mol.

The purpose of this article is to re-interpretate 'Post Catch-up Studies' on the Korean innovation system with the framework of 'Transition Studies'. The viewpoints of the vision, research area and system innovation process of Post Catch-up studies are reviewed and reconfigurated. The Transition Studies concepts of Sustainability, Coevolution of industry and society, and transition management are introduced into the Post-catch up Studies and discussed. It is suggested that Post catch-up studies should support sustainability system transition and make use of transition management tools for the sustainable post catch-up innovation and policy.

This paper aims to analyse post catch-up innovation activities of Korean firms. Traditional approach focused on incremental innovation through fast catch-up process. Recently, Korean firms present new patterns of innovation activities. It includes the development of state-of-the-art frontier products in capital intensive manufacturing sector, the achievement of architectural innovation through adopting newly developed components and the creation of new market based on the basic technological capabilities. This paper attempts to formulate conceptual framework for analysing post catch-up innovation activities and to analyse stylized facts of post catch-up activities based on the case studies on technology based small and medium Korean firms.

We proposed a three-dimensional holographic display technique without twin image noise by converting a complex hologram to an off-axis hologram. To implement the proposed technique we record the complex hologram of a three dimensional object that is composed of two slides located with different depth locations. We added spatial carrier to the complex hologram and after that, extract the real part of the spatial-carrier-added hologram. This converts the complex hologram to an off-axis hologram. We also reconstruct the off-axis hologram using a spatial light modulator for three dimensional display.

외국 기술을 모방하여 그 궤적을 따라가는 추격형 기술혁신모델의 한계가 노정되면서 새로운 기술혁신모델의 필요성이 증대하고 있다. 본 연구에서는 모방에 의거한 추격형 혁신활동을 넘어서는 탈추격형(post catch-up)기술혁신활동의 특성을 조감하는 작업을 수행했다. 특히 분석대상을 중소기업에 맞추어져 이들의 탈추격형 혁신활동 사례를 살펴보았다. 기술집약형 중소기업의 혁신활동의 활성화는 그 자체가 대기업 중심의 한국혁신체제의 전환을 보여주는 의미 있는 현상이기 때문이다.

When a man is called a person crossing borders(PCB), he is a man who pursues communication, coexistence and combination beyond visible and/or invisible borders of nations and disciplinaries. This paper examines Leibniz as a PCB in his life and learning, and how his metaphysics, the pre-established harmony, enabled him to be a PCB.

블록체인 기술의 발전과 중앙집중형 금융서비스의 취약성과 불신에 대한 우려가 커지면서 탈중앙화 금융(DeFi)과 탈중앙화 거래소(DEX)가 유망한 대안으로 떠올랐다. 본 논문에서는 특히 Uniswap에 초점을 맞춰 DeFi 내의 과제와 문제를 살펴본다. 우리는 DeFi 및 DEX의 현재 상태에 대한 배경 지식을 제공하여 MEV(Maximal Extractable Value) 공격에 대한 취약성을 강조한다. 우리의 접근 방식에는 MEV 공격 패턴을 식별하고 분석하기 위한 Uniswap에 구조 분석이 포함된다. 이 연구는 DEX 보안을 강화하고 MEV 위험을 완화하기 위한 귀중한 지침을 제공하여 DeFi 생태계의 이해관계자에게 필수적인 리소스 역할을 한다.

본 논문은 휠체어의 탑승자의 구동력과 BLDCM(Brushless DC Motor) 에서 출력되는 보조력인 전기적인 구동력을 동시에 사용하는 탈부착형 수전동 휠체어의 제어기를 제안한다. 제안된 방식에서는 탈부착형 수전동 휠체어 제어기는 휠체어의 기울기와 휠체어의 상관관계를 바탕으로, 탑승자의 휠체어 림 구동 상태를 추정하여 휠체어의 전동력을 전달하는 BLDCM에서 구동력을 사용자의 지령에 따라 보조하도록 제어한다. 사용자의 요구 상태는 림의 구동에 따른 휠체어의 상태를 가속도, 자이로 센서를 이용해 측정을 하게 되고, 이를 상보필터를 사용해 각도를 보정하여, 지령치를 계산하고, 구동부는 지령치에 따라 휠체어에 필요한 전동력을 발생하게 된다. 탈부착형 수전동 휠체어의 제어방식은 시뮬레이션을 통해 가능성을 검증하였다.
