In this study, I wanted to propose the design direction of the furniture and products in bathroom space so that the elderly's life is well supported to meet such aging societies that are getting older. Therefore, I have drawn the elders' needs by investigating their characteristics through literature research and used such needs as a frame of analysis to analyze the bathroom furniture and products made in Korea and foreign countries. The analysis results indicate:First, the elders need entertainment, health care, environment-friendly, convenience, good accessibility, chair-based bath and space separation; second, both Korean-made and foreign-made bathroom products are difficult to be controlled, invisible of font, hard to sustain the elders' bodies, inconvenient to be used and etc; and third, the design to solve such problems should be with intuitive user interface, easy control, better accessibility, the elders' moving patterns and living habits considered, health care, pro-environmental product. This study puts emphasis on the reflection of socio-cultural characteristics in designing bathroom furniture & items for aging society and requires more bathroom products with various designs in the foreseeable future.

본 논문에서는 복호화시 정확한 복원이 가능하며 윤곽 상태에 따라 효율적으로 부호화하는 여섯 방향 윤곽부호화 기법을 제안하였다. 먼저 방향벡터의 확률적 분포가 수평 수직 진행 방향과 대각선 진행 방향에서 서로 다르다는 사실에 근거하여 현재의 진행 방향을 두 상태로 나누고, 각 상태별로 다른 코드를 이용하여 부호화하였다. 그리고 부호화 효율을 더욱 높이기 위해 윤곽 상태를 현재 방향벡터와 이진 진행 방향벡터에 따라 다섯 가지로 구분하여 부호화하였다. 또한, 단말 코드워드를 제거함으로써 전체 코드워드 발생 횟수를 줄였다. 실험을 통하여 단말 코드를 제거하고 두 상태 및 다섯 상태로 나누었을 때 전체 엔트로피는 실영상에 대해서는 각각 12%, 14%정도, 합성영상에 대해서는 각각 10%, 26%정도로 크게 감소함을 확인할 수 있었다.

The purpose of this study is to find the proper width of fabric which can bring high efficiency on productivity. We focus on the marking method by comparing and analyzing the marking efficiency of A-line skirt. This study employs 4 criteria to mark the A-line skirt, which are cutting method, angle, width, and direction, respectively. There can be 2 different cutting methods(fold pattern and add seam pattern at the front and back center line), and 2 different angles(warp angle and bias angle). Also, width of the fabric can be classified into 2 groups(110cm, 150cm), and marking direction can be grouped into 2(one direction marker and one direction per each size marker). These 4 criteria make 16($2^*2^*2^*2$) cases for this study. Main findings are follows. First, the skirt with folded at the center line had higher efficiency rate than the skirt with add seam at the center line. Second, the skirt with the 150cm width has higher efficiency rate than that of 110cm. Third, fixing the warp angle has higher efficiency rate than that of fixing the bias angle at the front and back center line. Finally, one direction per each size marker has much higher efficiency than the one direction marker.

As consumption pattern and fashion communication become digitalized, fashion houses are being inherited by creative directors owing to their expanding role. While the roles and responsibilities of creative directors have been changing extensively along with the dynamic nature of the fashion industry, researches on creative directions have mostly focused on luxury brands. This study examined the creative direction of John Galliano for Maison Margiela, a conceptual brand to be maintained by a creative director. To analyze this, the authors established a creative direction analysis model constituting five elements: brand heritage, trend, democratization, brand status, and persona, drawing on the luxury brand architecture by Kapferer and Bastien. Thus, Galliano has maintained anonymity as a heritage of Maison Margiela, expanding the existing Replica lines, and introduced fashion shows focusing on current issues or social phenomena. As a democratization strategy, he directed the brand to associate with more popular brands or expanded diffusion lines to secure broader customer base, while demonstrating couturier-like showmanship in the media and establishing his own persona. His direction for Maison Margiela recreates and expands brand heritage by transforming the brand philosophy. Therefore the new creative direction communicates with the wider public and diversifies customer bases through democratization strategies, while building Galliano's own persona.

본 논문은 유니버설 디자인 원칙을 바탕으로 키오스크의 사용성을 높여 모든 사용자가 편리하게 사용하기 위한 키오스크 디자인 개선 방향을 연구하는 것이 목적이다. 키오스크 사용과 관련한 나이별 설문조사와 분석결과를 검증하는 추가 설문조사를 통해 필수 개선점을 도출하여 디자인 개선 방향을 연구하였다. 연구결과는 다음과 같다. 키오스크 화면 배경과 디자인 요소 간 높은 대비, yellow 계열의 색상, 아웃라인화 한 디자인 요소의 사용으로 가독성을 높인다. 그리고 10pt를 기준으로 폰트의 축소와 확대가 가능하도록 한다. 또한, 휠체어 탑승자를 고려하여 하단부 설계가 불가능한 영역과 키오스크가 낮추어져야 할 최소 높이를 도출하였다. 향후 키오스크 디자인 시에는 개인의 특성에 따라 키오스크의 기능이 다변화할 수 있도록 하는 디자인과 시스템이 필요하며 유니버설 디자인의 적용에 중점을 두어 디자인해야 한다. 본 연구는 연구대상이 한정적이므로 다양한 표본을 대상으로 한 추후 연구가 필요하며 색상과 가독성에 관련한 검증 연구도 추후 진행할 계획이다.

It is reported that the amount of reinforcements for domestic PSC box girder bridges is used two times more that those for foreign PSC box girder bridges, which is considered to be irrational and uneconomical. Therefore, we have come to the conclusion through this study that the advanced design direction can reduce the amount of reinforcements under the condition that the static load test and the nonlinear analysis for the specimen of the PSC box girder bridge with reduced reinforcements which is designed by advanced design direction was carried out in order to verify the validity of the advanced design direction.

In this paper feasible direction method which is one of the optimization method is adopted to natural frequency optimization. In order to find the optimum design of structures that have characteristic natural frequency range, a numerical optimization method to solving eigenvalue problems is a widely used approach. However most cases, it is difficult to decide the accurate thickness and shape of structures that have allowable natural frequency in design constraints. Parallel analysis algorithm involving the feasible direction optimization method and Rayleight-Ritz eigenvalue solving method is developed. The method is implemented by using finite element method. It calculated the optimal thickness and the thickness ratio of each element of 2-D plane element through the parallel algorithm method which satisfy the design constraint of natural frequency.

This paper focuses on codebook-based precoding for space-division multiple access/orthogonal frequency-division multiple access (SDMA-OFDMA) systems aiming to guarantee high throughput for their users as well as to mitigate interference to fixed satellite service (FSS). A systematic design of SDMA codebook for subband-based OFDMA is proposed, which forms multiple orthogonal beams with common spatial null in the direction of a victim FSS earth station (ES). The design enables both transmitter and receiver to independently construct identical codebook by sharing only on the direction angle of an FSS ES, which takes fewer overhead bits than Gram-Schmidt process, a general method satisfying our design criterion. A system-level throughput evaluation shows that the proposed precoding provides superior performance over existing spectrum sharing method, that is, subband deactivation. The spectrum sharing analysis shows that the proposed precoding, even with an estimation error of the direction angles of an FSS ES, causes lower interference than existing precoding, knockdown precoding.
