In this study, die turning injection(DTI) mold design for manufacturing reservoir fluid tanks used for cooling in-vehicle batteries, inverters, and motors was conducted based on multi-field CAE. Part design, performance evaluation, and mold design of the reservoir fluid tank was performed. The frequency response characteristics through modal and harmonic response analysis to satisfy the automotive performance test items for the designed part were examined. Analysis of re-melting characteristics and structural analysis of the driving part for designing the rotating die of the DTI mold were performed. Part design was possible when the natural frequency performance value of 32Hz or higher was satisfied through finite element analysis, and the temperature distribution and deformation characteristics of the part after injection molding were found through the first injection molding analysis. In addition, it can be seen that the temperature change of the primary part greatly influences the re-melting characteristics during the secondary injection. The minimum force for driving the turning die of the designed mold was calculated through structural analysis. Hydraulic system design was possible. Finally, a precise and efficient DTI mold design for the reservoir fluid tank was possible through presented multi-field CAE process.

Regeneration of abandoned industrial facilities can heighten the availability through potential values that cannot be found in newly-built buildings and through the sense of overscale space. Furthermore, backward regions can be activated by assigning their identity and establishing social-cultural infrastructures. The aim of the present study is to analyze and integrate of characteristics of design expression based on a case of creative space in Shanghai. A research on the creative space in Shanghi designedly proceeded according to government's extensive administrative support and policy. We keep appearances of industrial buildings as close as possible to their original condition, thereby revealing symbolism and forming unique characteristics that distinguish them from those of other areas. While keeping the shape characteristics of the bridge8, M50, Red Town, 2577 Greative Garden and 1933 Shanghai, we designed spaces in terms of spacial variability, oneness, accessibility and continuity and activated areas by inducing residents' participation and fostering art and cultural oriented facilities. These characteristics of design expression are factors to be considered in regenerating abandoned industrial facilities internally and hopefully they are used as a reference of design plan.

This study aims to investigate the socio-cultural background of Poulaines, which influenced fashion and contemporary shoe design. Analyzing the characteristics of the Poulaines provided basic data for different shoes. The study method utilized previous studies to explore the concept and characteristics of Poulaines. In the empirical analysis, shoe design data mainly came from collections that illustrate formative elements of contemporary shoe design from the 2010 S/S season to the 2020 S/S season. A total of 709 photo materials were collected and analyzed. The results showed that the morphological characteristics of Poulaines were exaggerated to symbolize classes of the past and sexual expression. The expanding structure was divided into the fore nose, heel, and top-line and featured a design that expressed the formative beauty of Poulaines. Additionally, the decorative desire to represent wealth and class using various materials introduced new designs into contemporary shoe designs while showing extreme decorativeness through over-trimming and color contrast. Furthermore, the heterogeneous characteristics that come from the change and harmony of the shoes' body and heel that deviated from the existing shoe shapes were classified into the dissolution of shapes and mixing and matching. Thus, they broke the monotonous silhouette of shoes and gave variety delicately.

This study aims to understand the concept of pixel, the most important factor in constituting a digital image, draw the formative characteristics of pixelation image expressed through non-digital media, and develop fashion design reflecting the characteristics. As a research method, the literature review was conducted in the present study by involving domestic and foreign publications, related academic journals, and theses and dissertations on the pixel and pixelation image based on a qualitative research process. In addition, through an analysis of the cases that borrowed pixelation images in non-digital media like contemporary art and design, etc., an attempt was made to draw the formative characteristics of the pixelation image. Apparently, six fashion design looks are presented in the present study. The formative characteristics of the pixelation image include: first, the repeatability that repeats the minimum unit; second, the incompleteness of the shape appearing through the phenomenon of aliasing due to the characteristics of the pixel; and third, the combination that completes the shape through the combination of individual independent pixels. The results of the expression through reflecting them in fashion design are as follows: first, this study chose one small geometric formative element and presented repeatability by repetitively expressing that element in a textile pattern; second, for incompleteness, this study expressed an incomplete form, handling the edge part of the shape with the method of disentangling the strand; and third, the combination by completing a single look through overlapping of independent textiles and the combination of different independent individuals is expressed.

Rider jackets were once reserved for military uniforms but have become an important styling item in recent fashion trends. The design characteristics of the rider jacket are rooted in symbolism, and the image associated with a rider jacket is in line with the challenging of authority and being a member of the rebellious youth subculture. Usually, young people with anti-social tendencies wore jackets, and some styles were used as a medium to express their emotional homogeneity, and they received favorable responses as the items represented them. The design characteristics of a rider jacket can be largely divided into resistance against the older generation, violence, challenging cultural norms, sexuality, and resistance, as well as embodying violent characteristics, including strength, courage. and male chauvinism. The reason for the development of these challenging characteristics are disparagement and anger of the lower class, who were excluded from mainstream society. Rider jackets can be viewed negatively due to the kind of message it is conveying against mainstream society. Among the sexual features were leather pants, short-length leather rider jackets, glossy metal accessories, and belt buckles, which also highlighted gay and decadent images that came to be associated with the jackets. The drapery created various kinds of wrinkles according to the way of dressing, and it had beautiful expressiveness while serving to express the body more beautifully. Drapery can be classified according to the aesthetic characteristics or expression techniques, and if the type of drapery is classified according to the morphological characteristics, it can be classified into variable and fixed structures, depending on whether the part to which the drapery is applied is fluid or not. In other words, it depends on the dressing method or the intention, and if the drapery technique is directly applied to the garment or is attached to the form. This fashion design proposal may have the greatest significance in that it sought to propose a new style incorporating a drapery technique with a strong feminine image to a rider jacket, which traditionally was associated with a masculine image.

A detailed computational fluid dynamics (CFD) simulation analysis model was developed using ANSYS CFX 16.1 and analyzed to simulate the basic design and internal flow characteristics of a 180 MW small modular reactor (SMR) with a natural circulation flow system. To analyze the natural circulation phenomena without a pump for the initial flow generation inside the reactor, the flow characteristics were evaluated for each output assuming various initial powers relative to the critical condition. The eddy phenomenon and the flow imbalance phenomenon at each output were confirmed, and a flow leveling structure under the core was proposed for an optimization of the internal natural circulation flow. In the steady-state analysis, the temperature distribution and heat transfer speed at each position considering an increase in the output power of the core were calculated, and the conceptual design of the SMR had a sufficient thermal margin (31.4 K). A transient model with the output ranging from 0% to 100% was analyzed, and the obtained values were close to the T_hot and T_cold temperature difference value estimated in the conceptual design of the SMR. The K-factor was calculated from the flow analysis data of the CFX model and applied to an analysis model in RELAP5/MOD3.3, the optimal analysis system code for nuclear power plants. The CFX analysis results and RELAP analysis results were evaluated in terms of the internal flow characteristics per core output. The two codes, which model the same nuclear power plant, have different flow analysis schemes but can be used complementarily. In particular, it will be useful to carry out detailed studies of the timing of the steam generator intervention when an SMR is activated. The thermal and hydraulic characteristics of the models that applied porous media to the core & steam generators and the models that embodied the entire detail shape were compared and analyzed. Although there were differences in the ability to analyze detailed flow characteristics at some low powers, it was confirmed that there was no significant difference in the thermal hydraulic characteristics' analysis of the SMR system's conceptual design.

This paper describes a 3-phase Line-Interactive APF system and analyzes its operating characteristics considering LC Filter output characteristics. Topology of APF is similar to that of Off-Line UPS in the point of parallelly operating inverter system. So it is possible to be multi-functioned active compensating system according to power condition. Likewise this actively operating system from APF to UPS and vice versa is often to be called Line-Interactive system. And more than that Line-Interactive system needs precise design of LC filter on converter output side to make this system fully operate in both APF and UPS modes. The problem in this point is how to design LC Filter to be contented with two different system characteristics so this paper analyzes this problem and proposes its design procedures. Then suggested filter design is verified to be contented by the simulations and experimental results

The design methods of mechanical systems are largely classified into deterministic methods and stochastic methods. In deterministic methods, design parameters are assumed to have fixed values. On the other hand, in stochastic methods, design parameters are assumed to be statistically distributed. When a stochastic method is employed, statistical characteristics of the populations of design variables are assumed to be known. However, very often, it is almost impossible or very expensive to obtain the statistical characteristics of the populations. Therefore a sample survey method is usually employed for stochastic methods. This paper describes the procedure of estimating the statistical characteristics of populations by employing sample data sets. An example of AFM micro cantilever beam is employed to show the effectiveness of the procedure.
