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.

In this paper, we present efficient six-connected contour coding algorithms which can uniquely reconstruct any contour image and efficiently compress the contour data. We first design chain difference codes using two onward direction states, based on the fact that the probability distribution of the direction vectors of horiwntal/vertical direction state is different from that of the direction vectors of diagonal direction state. In order to increase coding efficiency, we also design chain difference codes using five states which are classified according to current and previous onward direction vectors. In addition, we also remove the END codeword to reduce total codeword occurrency. Experimental results show that when using 2 states and 5 states without END codeword total entropy decreases by about 12% and 14% for real images and by about 10% and 26% for a synthetic image, respectively.

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.

The purpose of this paper is to study the direction of improving kiosk design for convenient use by all users by increasing the usability of kiosks based on universal design principles. The direction of design improvement was studied by deriving essential improvements through additional surveys verifying the results of age-specific surveys and analysis related to the use of kiosks. The results of the study are as follows. High contrast between kiosk screen background and design elements, yellow color, and outline design elements increase readability. Then, reduce and enlarge the font based on 10pt. In addition, in consideration of wheelchair passengers, the area where the lower part cannot be designed and the minimum height of adjusting the height of the kiosk were derived. In the future, kiosk design requires a design and system that can diversify the functions of kiosks according to individual characteristics, and design should be focused on the application of universal design. Since this study has limited research subjects, further studies on various samples are required, and verification studies related to color and readability will also be conducted.

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.
