In this paper, the stress, buckling and vibration analyses have been performed for several case with the spot weld stiffened rear side frame, the unstiffened rear side frame and the dual thickness laser weld rear side frame. For stress and vibration analyses, the clamped boundary condition with spring supports are used. But for the buckling analyses, the both ends simply supported boundary conditions are used. For the nummerical analyses, ANSYS 5.0 code is adopted. Maximum stress of the spot weld stiffened rear side frame occurs in the main frame and is 80.9 MPa. Maximum strain is 501 .mu.. The maximum stress of the dual thickness laser weld rear side frame of 1.8mm thickness structure is equal with the stress of spot weld stiffened frame. The weight of dual thickness laser weld frame can be reduced about 17.2%. For the stiffened spot weld rear side frame with both ends simply supported boundary conditon, the bucking load is 52.54 kN. When the thickness of the dual thickness laser weld rear side frame become 1.9mm thickness structure, the buckling load of the stiffenerd rear side frame is equal to that of dual thickness laser weld frame. The reduction of the structure weight is about 5%. The fundamental natural frequency of the stiffened spot weld rear side frame for bending mode is 163.6 Hz and that of the dual thickness laser weld rear side frame is 179.8 Hz.

The purpose of this study is to find the way of enhancing readability with Anti-Aliasing in digital media environment. Subjects of this paper were established analyzing Anti-Aliasing & Multiple Anti-Aliasing. First, this study is to find a actual condition of using Anti-Aliasing in digital media environment. Then Gathered the information of Multiple Anti-Aliasing samples from internat. I made enhancing readablity result with that information and tested this result for finding the best result for readability. This study will present the guid line for the person who is working as a designer in field to find the best result for readability with Multiple Anti-Aliasing. Also, will show us a readablity's possibility of using Multiple Anti-Aliasing for next verson of graphic software.

The importance of barrier free is being highlighted worldwide. This study attempted to identify barrier-free research trends using text mining. Through this, it was intended to help with research and policies to create a barrier free environment. The analysis data is 227 papers published in domestic academic journals from 1996 when barrier free research began to 2022. The researcher converted the title, keywords, and abstract of an academic thesis into text, and then analyzed the pattern of the thesis and the meaning of the data. The summary of the research results is as follows. First, barrier-free research began to increase after 2009, with an annual average of 17.1 papers being published. This is related to the implementation guidelines for the barrier-free certification system that took effect on July 15, 2008. Second, results of barrier-free text mining i) As a result of word frequency analysis of top keywords, important keywords such as barrier free, disabled, design, universal design, access, elderly, certification, improvement, evaluation, and space, facility, and environment were searched. ii) As a result of TD-IDF analysis, the main keywords were universal design, design, certification, house, access, elderly, installation, disabled, park, evaluation, architecture, and space. iii) As a result of N-Ggam analysis, barrier free+certification, barrier free+design, barrier free+barrier free, elderly+disabled, disabled+elderly, disabled+convenience facilities, the disabled+the elderly, society+the elderly, convenience facilities+installation, certification+evaluation index, physical+environment, life+quality, etc. appeared in a related language. Third, as a result of the CONCOR analysis, cluster 1 was barrier-free issues and challenges, cluster 2 was universal design and space utilization, cluster 3 was Improving Accessibility for the Disabled, and cluster 4 was barrier free certification and evaluation. Based on the analysis results, this study presented policy implications for vitalizing barrier-free research and establishing a desirable barrier free environment.

셀프 인테리어와 '온라인 집들이' 열풍은 DIY 문화의 확산, 1인 가구의 증가, SNS를 통한 이미지 공유의 증가 등 다양한 문화 현상의 교차 지점에 위치한다. 본 연구는 대표적인 인테리어 정보 공유 및 커머스 플랫폼인 '오늘의 집'에 게시된 온라인 집들이의 구체적 예시를 통해 청년 1인 가구의 셀프 인테리어에 대해 고찰하였다. 경제적, 공간적, 주거 방식의 제약은 이들의 셀프 인테리어 스타일을 형성하는 데 영향을 미쳤다. 낮고, 단순하며, 가벼운 가구, 작고 저렴한 소품 및 장식들은 '내추럴' 혹은 '모던' 이라고 불리는 스타일로 포장되었다.

본 연구에서는 (1) 인테리어에 대한 감성어휘모형을 도출하고, (2) 거실 인테리어의 주요 배색을 추출한 후, (3) 거실 공간의 배색 감성모형을 개발하였으며, (4) 연구결과를 토대로 거실 인테리어 디자인을 위한 배색기법을 제시하였다. 이를 위하여 인테리어를 기술하는 감성어휘를 수집하고 이들로부터 대표적 감성어휘를 추출, 감성어휘척도를 구성하였다. 감성조사분석을 통해 '따뜻하다-차갑다'(제 1차원), '고급스럽다-소박하다(제 2차원)', '현대적이다-고전적이다'(제3차원)의 세 차원축이 도출되었고, 이렇게 도출된 감성공간 상에 감성어휘들을 대응시키고, 9개의 감성 범주로 구분함으로써 감성어휘모형을 개발하였다. 한편, 거실 인테리어의 주요 배색을 추출하여 배색자극물을 개발하고, 감성어휘모형과의 관계분석을 통해 거실 공간의 배색 감성모형을 개발하였다. 최종적으로, 배색 감성모형에서 도출된 9개의 감성범주와 그에 대응하는 배색을 기반으로 하여 거실용 인테리어 디자인의 핵심이미지에 따른 배색지침을 제시하였다.

모바일 입력솔루션 전문업체 크루셜텍이 에어리어(Area) 방식 지문인식(BTP, Biometric TrackPad) 솔루션을 개발했다. 에어리어 방식은 손가락을 훑어 내리며 지문 정보를 합성해 분석하는 스와이프 방식과 달리 일정 영역에 손가락을 대면 지문이 읽혀 상대적으로 인식률이 높은 것이 장점이다.
